Obesity and CRC link ‘may be underestimated’
and so would not reflect prediagnostic weight loss linked to the condition, a new analysis suggests.
Obesity, assessed using BMI, was associated with a twofold higher risk of CRC 8-10 years prior to diagnosis, while weight loss of 2 kg or more within 2 years of diagnosis was associated with a “dramatic” 7.52-fold increased risk of CRC, the researchers said.
The results “illustrate the dramatic change of BMI as a risk factor associated with CRC, depending on whether the period of potential prediagnostic weight loss is accounted for or not,” Hermann Brenner, MD, MPH, of the German Cancer Research Center, Heidelberg, and colleagues conclude.
The study was published online in JAMA Network Open.
Recent evidence suggests that obesity is associated with an estimated 30% greater risk of CRC. But the extent to which excess body weight influences CRC risk may be underestimated because prediagnostic weight loss has historically been overlooked.
To understand how prediagnostic weight loss could affect the associations found between excess weight and CRC risk, the researchers examined weight data on almost 6,500 patients newly diagnosed with CRC and more than 5,400 control persons who were matched for age, sex, and country of residence. The median age of the cohort was 69 years, and 60.3% were men.
At the time of recruitment, 62% of case patients and 66% of control patients were overweight or obese. No association was found between current BMI and CRC risk.
However, when using patients’ weight from 8-10 years before CRC diagnosis, the researchers found a significant positive association between overweight or obesity and CRC risk (adjusted odds ratio, 1.27 for overweight and 2.09 for obesity). The risk for CRC increased significantly for every 5-unit increase in BMI (aOR, 1.35). These results were similar when the patients were stratified by sex and CRC subsites.
The researchers also found that weight loss of 2 kg or more within 2 years of CRC diagnosis or interview was associated with a 7.52-fold increased risk for CRC.
“While we demonstrated that prediagnostic weight loss is a major concern for CRC,” such prediagnostic weight loss “may play a similarly important role for other cancers and noncancer diseases associated with overweight and obesity,” the authors note.
“Most importantly, however, our results emphasize the importance of interventions aimed at preventing and managing overweight and obesity ... and which may factor more substantially into CRC risk and other obesity-related diseases than suggested by existing epidemiological evidence,” they write.
The study was supported in part by grants from the German Research Council and the German Federal Ministry of Education and Research. The authors have disclosed no relevant financial relationships.

What are the healthiest drinks for patients with type 2 diabetes?
The researchers examined data on almost 15,500 participants with type 2 diabetes from two major studies, finding that the highest level of consumption of SSBs was associated with a 20% increased risk of all-cause mortality and a 25% raised risk of cardiovascular disease, compared with consumption of the least amounts of these products.
The research, published in BMJ, also showed that drinking coffee, tea, plain water, and low-fat milk reduced the risk of all-cause death and that switching from SSBs to the other beverages was linked to lower mortality.
“Overall, these results provide additional evidence that emphasizes the importance of beverage choices in maintaining overall health among adults with diabetes,” say senior author Le Ma, PhD, department of nutrition, Harvard School of Public Health, Boston, and colleagues.
“Collectively, these findings all point in the same direction. Lower consumption of SSBs and higher consumption of coffee, tea, plain water, or low-fat milk are optimal for better health outcomes in adults with type 2 diabetes,” Nita G. Forouhi, MD, PhD, emphasizes in an accompanying editorial.
Choice of drink matters
Dr. Forouhi, from the University of Cambridge (England), warned, however, that the findings “cannot be considered cause and effect,” despite the large-scale analysis.
Moreover, “questions remain,” such as the impact of beverage consumption on coronary heart disease and stroke risk, and cancer mortality, with the current study providing “inconclusive” data on the latter.
There was also no data on the addition of sugar to tea or coffee, “so the comparative health effects of unsweetened and sweetened hot beverages remain unclear,” Dr. Forouhi points out. Also unknown is whether the type of tea consumed has a differential effect.
Despite these and other reservations, she says that overall, “Choice of beverage clearly matters.”
“The case for avoiding sugar-sweetened beverages is compelling, and it is supported by various fiscal measures in more than 45 countries. It is reasonable to shift the focus to drinks that are most likely to have positive health impacts: coffee, tea, plain water, and low-fat milk,” she notes.
Dr. Forouhi ends by underlining that the current findings tally with those seen in the general population, so “one important message is that having diabetes does not have to be especially restrictive.”
Expanding the evidence
It was estimated that 537 million adults worldwide had type 2 diabetes in 2021, a figure set to increase to 783 million by 2045, say the authors.
Individuals with type 2 diabetes have an increased risk of cardiovascular disease, among many other comorbidities, as well as premature death. Dietary interventions can play an important role in managing these risks.
Recommendations on the healthiest beverages to drink are largely based on evidence from the general population, and data are limited on the best options for adults with type 2 diabetes, who have altered metabolism, the researchers note.
To expand on this, they examined data from the Nurses’ Health Study, which enrolled female registered nurses aged 30-55 years and was initiated in 1976, and the Health Professionals Follow-Up Study, which included male health professionals aged 40-75 years and was initiated in 1996.
For the current analysis, 11,399 women and 4,087 men with type 2 diabetes were included from the two studies, of whom 2,715 were diagnosed before study entry.
Participants’ average daily beverage intake was assessed using a validated food frequency questionnaire administered every 2-4 years. SSBs included caffeinated and caffeine-free colas, other carbonated SSBs, and noncarbonated SSBs, such as fruit punches, lemonades, or other fruit drinks.
During 285,967 person-years of follow-up, there were 7,638 (49.3%) deaths, and 3,447 (22.3%) cases of incident cardiovascular disease were documented during 248,447 person-years of follow-up.
Fully adjusted multivariate analysis comparing the lowest and highest beverage intake indicated that SSBs were associated with a significant increase in all-cause mortality, at a pooled hazard ratio of 1.20, or 1.08 for each additional serving per day (P = .01).
In contrast, the associations between all-cause mortality and consumption of artificially sweetened beverages, fruit juice, and full-fat milk were not significant, whereas coffee (HR, 0.74), tea (HR, 0.79), plain water (HR, 0.77), and low-fat milk (HR, 0.88) were linked to a reduced risk.
The team reported that there were similar associations between beverage intake and cardiovascular disease incidence, at an HR of 1.25 for SSBs, as well as for cardiovascular disease mortality, at an HR of 1.29.
Participants who increased their tea, coffee, and low-fat milk consumption during the course of the study had lower all-cause mortality than those who did not. Switching from SSBs to other beverages was also associated with lower mortality.
The researchers note, however, that there are “several potential limitations” to their study, including that “individual beverage consumption may be correlated with other dietary and lifestyle risk factors for cardiovascular disease incidence and mortality among adults with [type 2] diabetes.”
The study was sponsored by the National Institutes of Health. Dr. Ma has reported no relevant financial relationships. Disclosures for the other authors are listed with the article. Dr. Forouhi has declared receiving support from the U.K. Medical Research Council Epidemiology Unit and U.K. National Institute for Health and Care Research Biomedical Research Centre Cambridge.

Intermittent fasting plus early eating may prevent type 2 diabetes
, indicate the results of a randomized controlled trial.
The study involved more than 200 individuals randomized to one of three groups: eat only in the morning (from 8:00 a.m. to noon) followed by 20 hours of fasting 3 days per week and eat as desired on the other days; daily calorie restriction to 70% of requirements; or standard weight loss advice.
The IF plus early time-restricted eating intervention was associated with a significant improvement in a key measure of glucose control versus calorie restriction at 6 months, while both interventions were linked to benefits in terms of cardiovascular risk markers and body composition, compared with the standard weight loss advice.
However, the research, published in Nature Medicine, showed that the additional benefit of IF plus early time-restricted eating did not persist, and less than half of participants were still following the plan at 18 months, compared with almost 80% of those in the calorie-restriction group.
“Following a time-restricted, IF diet could help lower the chances of developing type 2 diabetes,” senior author Leonie K. Heilbronn, PhD, University of Adelaide, South Australia, said in a press release.
This is “the largest study in the world to date, and the first powered to assess how the body processes and uses glucose after eating a meal,” with the latter being a better indicator of diabetes risk than a fasting glucose test, added first author Xiao Tong Teong, a PhD student, also at the University of Adelaide.
“The results of this study add to the growing body of evidence to indicate that meal timing and fasting advice extends the health benefits of a restricted-calorie diet, independently from weight loss, and this may be influential in clinical practice,” Ms. Teong added.
Adherence difficult to IF plus early time-restricted eating
Asked to comment, Krista Varady, PhD, said that the study design “would have been stronger if the time-restricted eating and IF interventions were separated” and compared.
“Time-restricted eating has been shown to naturally reduce calorie intake by 300-500 kcal/day,” she said in an interview, “so I’m not sure why the investigators chose to combine [it] with IF. It ... defeats the point of time-restricted eating.”
Dr. Varady, who recently coauthored a review of the clinical application of IF for weight loss, also doubted whether individuals would adhere to combined early time-restricted eating and IF. “In all honesty, I don’t think anyone would follow this diet for very long,” she said.
She added that the feasibility of this particular approach is “very questionable. In general, people don’t like diets that require them to skip dinner with family/friends on multiple days of the week,” explained Dr. Varady, professor of nutrition at the University of Illinois, Chicago. “These regimens make social eating very difficult, which results in high attrition.
“Indeed, evidence from a recent large-scale observational study of nearly 800,000 adults shows that Americans who engage in time-restricted eating placed their eating window in the afternoon or evening,” she noted.
Dr. Varady therefore suggested that future trials should test “more feasible time-restricted eating approaches,” such as those with later eating windows and without “vigilant calorie monitoring.”
“These types of diets are much easier to follow and are more likely to produce lasting weight and glycemic control in people with obesity and prediabetes,” she observed.
A novel way to cut calories?
The Australian authors say there is growing interest in extending the established health benefits of calorie restriction through new approaches such as timing of meals and prolonged fasting, with IF – defined as fasting interspersed with days of ad libitum eating – gaining in popularity as an alternative to simple calorie restriction.
Time-restricted eating, which emphasizes shorter daily eating windows in alignment with circadian rhythms, has also become popular in recent years, although the authors acknowledge that current evidence suggests any benefits over calorie restriction alone in terms of body composition, blood lipids, or glucose parameters are small.
To examine the combination of IF plus early time-restricted eating, in the DIRECT trial, the team recruited individuals aged 35-75 years who had a score of at least 12 on the Australian Type 2 Diabetes Risk Assessment Tool but did not have a diagnosis of diabetes and had stable weight for more than 6 months prior to study entry.
The participants were randomized to one of three groups:
- IF plus early time-restricted eating, which allowed consumption of 30% of calculated baseline energy requirements between 8:00 a.m. and midday, followed by a 20-hour fast from midday on 3 nonconsecutive days per week. They consumed their regular diet on nonfasting days.
- Calorie restriction, where they consumed 70% of daily calculated baseline energy requirements each day and were given rotating menu plans, but no specific mealtimes.
- Standard care, where they were given a booklet on current guidelines, with no counseling or meal replacement.
There were clinic visits every 2 weeks for the first 6 months of follow-up, and then monthly visits for 12 months. The two intervention groups had one-on-one diet counseling for the first 6 months. All groups were instructed to maintain their usual physical activity levels.
A total of 209 individuals were enrolled between Sept. 26, 2018, and May 4, 2020. Their mean age was 58 years, and 57% were women. Mean body mass index was 34.8 kg/m2.
In all, 40.7% of participants were allocated to IF plus early time-restricted eating, 39.7% to calorie restriction, and the remaining 19.6% to standard care.
The results showed that IF plus early time-restricted eating was associated with a significantly greater improvement in the primary outcome of postprandial glucose area under the curve (AUC) at month 6 compared with calorie restriction, at –10.1 mg/dL/min versus –3.6 mg/dL/min (P = .03).
“To our knowledge, no [prior] studies have been powered for postprandial assessments of glycemia, which are better indicators of diabetes risk than fasting assessment,” the authors underlined.
IF plus early time-restricted eating was also associated with greater reductions in postprandial insulin AUC versus calorie restriction at 6 months (P = .04). However, the differences between the IF plus early time-restricted eating and calorie restriction groups for postmeal insulin did not remain significant at 18 months of follow-up.
Both IF plus early time-restricted eating and calorie restriction were associated with greater reductions in A1c levels at 6 months versus standard care, but there was no significant difference between the two active interventions (P = .46).
Both interventions were also associated with improvements in markers of cardiovascular risk versus standard care, such as systolic blood pressure at 2 months, diastolic blood pressure at 6 months, and fasting triglycerides at both time points, with no significant differences between the two intervention groups.
IF plus early time-restricted eating and calorie restriction were also both associated with greater reductions in BMI and fat mass in the first 6 months, as well as in waist circumference.
Calorie restriction easier to stick to, less likely to cause fatigue
When offered the chance to modify their diet plan at 6 months, 46% of participants in the IF plus early time-restricted eating group said they would maintain 3 days of restrictions per week, while 51% chose to reduce the restrictions to 2 days per week.
In contrast, 97% of those who completed the calorie-restriction plan indicated they would continue with their current diet plan.
At 18 months, 42% of participants in the IF plus early time-restricted eating group said they still undertook 2-3 days of restrictions per week, while 78% of those assigned to calorie restriction reported that they followed a calorie-restricted diet.
Fatigue was more common with IF plus early time-restricted eating, reported by 56% of participants versus 37% of those following calorie restriction, and 35% of those in the standard care group at 6 months. Headaches and constipation were more common in the intervention groups than with standard care.
The study was supported by a National Health and Medical Research Council Project Grant, an Australian Government Research Training Program Scholarship from the University of Adelaide, and a Diabetes Australia Research Program Grant.
No relevant financial relationships were declared.

In general, people don’t like diets that require them to skip dinner with family/friends on multiple days of the week,” explained Dr. Varady, professor of nutrition at the University of Illinois, Chicago. “These regimens make social eating very difficult, which results in high attrition.
“Indeed, evidence from a recent large-scale observational study of nearly 800,000 adults shows that Americans who engage in time-restricted eating placed their eating window in the afternoon or evening,” she noted.
Dr. Varady therefore suggested that future trials should test “more feasible time-restricted eating approaches,” such as those with later eating windows and without “vigilant calorie monitoring.”
“These types of diets are much easier to follow and are more likely to produce lasting weight and glycemic control in people with obesity and prediabetes,” she observed.
A novel way to cut calories?
The Australian authors say there is growing interest in extending the established health benefits of calorie restriction through new approaches such as timing of meals and prolonged fasting, with IF – defined as fasting interspersed with days of ad libitum eating – gaining in popularity as an alternative to simple calorie restriction.
Time-restricted eating, which emphasizes shorter daily eating windows in alignment with circadian rhythms, has also become popular in recent years, although the authors acknowledge that current evidence suggests any benefits over calorie restriction alone in terms of body composition, blood lipids, or glucose parameters are small.
To examine the combination of IF plus early time-restricted eating, in the DIRECT trial, the team recruited individuals aged 35-75 years who had a score of at least 12 on the Australian Type 2 Diabetes Risk Assessment Tool but did not have a diagnosis of diabetes and had stable weight for more than 6 months prior to study entry.
The participants were randomized to one of three groups:
- IF plus early time-restricted eating, which allowed consumption of 30% of calculated baseline energy requirements between 8:00 a.m. and midday, followed by a 20-hour fast from midday on 3 nonconsecutive days per week. They consumed their regular diet on nonfasting days.
- Calorie restriction, where they consumed 70% of daily calculated baseline energy requirements each day and were given rotating menu plans, but no specific mealtimes.
- Standard care, where they were given a booklet on current guidelines, with no counseling or meal replacement.
There were clinic visits every 2 weeks for the first 6 months of follow-up, and then monthly visits for 12 months. The two intervention groups had one-on-one diet counseling for the first 6 months. All groups were instructed to maintain their usual physical activity levels.
A total of 209 individuals were enrolled between Sept. 26, 2018, and May 4, 2020. Their mean age was 58 years, and 57% were women. Mean body mass index was 34.8 kg/m2.
In all, 40.7% of participants were allocated to IF plus early time-restricted eating, 39.7% to calorie restriction, and the remaining 19.6% to standard care.
The results showed that IF plus early time-restricted eating was associated with a significantly greater improvement in the primary outcome of postprandial glucose area under the curve (AUC) at month 6 compared with calorie restriction, at –10.1 mg/dL/min versus –3.6 mg/dL/min (P = .03).
“To our knowledge, no [prior] studies have been powered for postprandial assessments of glycemia, which are better indicators of diabetes risk than fasting assessment,” the authors underlined.
IF plus early time-restricted eating was also associated with greater reductions in postprandial insulin AUC versus calorie restriction at 6 months (P = .04). However, the differences between the IF plus early time-restricted eating and calorie restriction groups for postmeal insulin did not remain significant at 18 months of follow-up.
Both IF plus early time-restricted eating and calorie restriction were associated with greater reductions in A1c levels at 6 months versus standard care, but there was no significant difference between the two active interventions (P = .46).
Both interventions were also associated with improvements in markers of cardiovascular risk versus standard care, such as systolic blood pressure at 2 months, diastolic blood pressure at 6 months, and fasting triglycerides at both time points, with no significant differences between the two intervention groups.
IF plus early time-restricted eating and calorie restriction were also both associated with greater reductions in BMI and fat mass in the first 6 months, as well as in waist circumference.
Calorie restriction easier to stick to, less likely to cause fatigue
When offered the chance to modify their diet plan at 6 months, 46% of participants in the IF plus early time-restricted eating group said they would maintain 3 days of restrictions per week, while 51% chose to reduce the restrictions to 2 days per week.
In contrast, 97% of those who completed the calorie-restriction plan indicated they would continue with their current diet plan.
At 18 months, 42% of participants in the IF plus early time-restricted eating group said they still undertook 2-3 days of restrictions per week, while 78% of those assigned to calorie restriction reported that they followed a calorie-restricted diet.
Fatigue was more common with IF plus early time-restricted eating, reported by 56% of participants versus 37% of those following calorie restriction, and 35% of those in the standard care group at 6 months. Headaches and constipation were more common in the intervention groups than with standard care.

, indicate the results of a randomized controlled trial.
The study involved more than 200 individuals randomized to one of three groups: eat only in the morning (from 8:00 a.m. to noon) followed by 20 hours of fasting 3 days per week and eat as desired on the other days; daily calorie restriction to 70% of requirements; or standard weight loss advice.
The IF plus early time-restricted eating intervention was associated with a significant improvement in a key measure of glucose control versus calorie restriction at 6 months, while both interventions were linked to benefits in terms of cardiovascular risk markers and body composition, compared with the standard weight loss advice.
However, the research, published in Nature Medicine, showed that the additional benefit of IF plus early time-restricted eating did not persist, and less than half of participants were still following the plan at 18 months, compared with almost 80% of those in the calorie-restriction group.
“Following a time-restricted, IF diet could help lower the chances of developing type 2 diabetes,” senior author Leonie K. Heilbronn, PhD, University of Adelaide, South Australia, said in a press release.
This is “the largest study in the world to date, and the first powered to assess how the body processes and uses glucose after eating a meal,” with the latter being a better indicator of diabetes risk than a fasting glucose test, added first author Xiao Tong Teong, a PhD student, also at the University of Adelaide.
“The results of this study add to the growing body of evidence to indicate that meal timing and fasting advice extends the health benefits of a restricted-calorie diet, independently from weight loss, and this may be influential in clinical practice,” Ms. Teong added.
Adherence difficult to IF plus early time-restricted eating
Asked to comment, Krista Varady, PhD, said that the study design “would have been stronger if the time-restricted eating and IF interventions were separated” and compared.
“Time-restricted eating has been shown to naturally reduce calorie intake by 300-500 kcal/day,” she said in an interview, “so I’m not sure why the investigators chose to combine [it] with IF. It ... defeats the point of time-restricted eating.”
Dr. Varady, who recently coauthored a review of the clinical application of IF for weight loss, also doubted whether individuals would adhere to combined early time-restricted eating and IF. “In all honesty, I don’t think anyone would follow this diet for very long,” she said.

Anger in adults a red flag for childhood trauma
PARIS –
Investigators examined data on more than 2,250 individuals who were asked about trauma during childhood and a subsequent tendency toward anger or angry outbursts 4 years later.
Results showed that emotional neglect during childhood was associated with approximately a 40% increased likelihood of subsequent anger, while psychological abuse was linked to a 30% increased likelihood.
Childhood physical abuse was also significantly associated with anger in adults, with an increased risk of approximately 40%. The researchers found no link between childhood sexual abuse and adult anger.
“We can’t definitively say that the trauma causes the anger, but the link is clear,” study investigator Nienke De Bles, PhD student, department of psychiatry, Leiden (the Netherlands) University Medical Center, said in a news release.
“Being easily angered can have several consequences,” she continued. “It can make personal interactions more difficult, and it can have consequences for your mental health and well-being, but people who get angry easily also have a greater tendency to discontinue psychiatric treatment, so this anger may mean that it reduces their chances of a better life,” she added.
Ms. De Bles believes that “it should be standard practice to ask depression and anxiety sufferers about anger and past trauma, even if the patient is not exhibiting current anger.”
The findings were presented at the European Psychiatric Association 2023 Congress.
A ‘red flag’ for abuse
“Psychiatric treatments for past trauma may differ from treatments for depression, so psychiatrists need to try to understand the cause so that they can offer the correct treatment to each patient,” said Ms. De Bles.
Ms. De Bles noted that childhood trauma has many negative consequences later in life and that it is associated with a higher prevalence of adult depression and anxiety.
“There are several potential mechanisms for psychopathology in the context of childhood trauma, and emotion regulation seems to be one of the key mechanisms,” she said.
The researchers previously found that anger was highly prevalent among patients with affective disorders. It was present in 30% of those with current anxiety or depressive disorder and in 40% of those with comorbid depression and anxiety with a tendency toward anger versus 5% of healthy control persons.
Other studies have shown that anger is associated with poor treatment outcomes and dropping out of treatment.
To further investigate the link between childhood trauma and anger in adulthood, the researchers examined data on 2,271 participants in the Netherlands Study of Depression and Anxiety (NESDA).
Childhood trauma was assessed at baseline using the semistructured Childhood Trauma Interview. Anger was measured at a 4-year follow-up using the Spielberger Trait Anger Subscale, the Anger Attacks Questionnaire, and the borderline and antisocial subscales of the Personality Disorder Questionnaire 4 to identify cluster B personality traits.
Results showed that emotional neglect during childhood was significantly associated with trait anger in adulthood, at an adjusted odds ratio of 1.42 (P < .001), anger attacks (OR, 1.35; P = .004), and borderline (OR, 1.76; P < .001) and antisocial (OR, 1.88; P = .001) personality traits.
Childhood psychological abuse was also significantly associated with later trait anger (OR, 1.28; P = .002), anger attacks (OR, 1.31; P = .024), and borderline (OR, 1.77; P < .001) and antisocial (OR, 1.69; P = .011) traits.
There was also a significant association between childhood psychical abuse and trait anger in adulthood (OR, 1.37; P < .001), anger attacks (OR, 1.48; P = .004), and borderline (OR, 1.71; P < .001) and antisocial (OR, 1.98; P = .002) traits.
There was no significant association between sexual abuse experienced in childhood and later anger or personality traits.
Ms. De Bles said the findings suggest “there is indeed a relationship between childhood trauma and anger in adulthood, and this is something that might be interesting for clinicians, as anger could be a red flag for a history of childhood trauma.”
She said in an interview that anger is a “very normal human emotion” but that it has not been as widely studied as sadness and anxiety.
She suggested that future research could examine the use of trauma-based therapies for patients with a history of childhood trauma and anger.
Overlooked, neglected
Commenting on the findings, Nur Hani Zainal, PhD, department of healthcare policy, Harvard Medical School, Boston, said the findings are “very consistent with the current biopsychosocial models in psychiatry and clinical psychology.”
Dr. Zainal, who was coauthor of a recent study that showed that anger appears to mediate the relationship between childhood trauma and adult psychopathology, said the current study offers a “good, incremental contribution” to the literature.
She noted there are “good uses” for the emotion of anger, as “sometimes we need anger to set healthy boundaries for ourselves.” However, she agreed that, as an aspect of depression, anxiety, and posttraumatic stress disorder, it is often “overlooked.”
Dr. Zainal said that the findings reinforce the importance of thoroughly evaluating adult patients’ experiences during childhood.
Julian Beezhold, MD, secretary general of the EPA and a consultant psychiatrist with the Norwich (England) Medical School, University of East Anglia, commented in the release that anger is a “somewhat neglected symptom.
“The findings are in line with what we see in day-to-day clinical practice and will hopefully help increase the awareness of the importance of both anger and associated childhood trauma.”
The infrastructure for the NESDA study is funded through the Geestkracht program of the Netherlands Organization for Health Research and Development and financial contributions by participating universities and mental health care organizations. The authors disclosed no relevant financial relationships.

AT EPA 2023
Single-dose psilocybin promising for resistant depression
PARIS –
Known as COMP360, the synthetic agent, a proprietary, purified form of psilocybin, improved symptoms related to mood and anhedonia while leaving aspects such as appetite and weight changes unaffected, reported investigators led by Guy M. Goodwin, PhD, emeritus professor of psychiatry, University of Oxford, England, and chief medical officer, COMPASS Pathways.
The study was presented at the European Psychiatric Association (EPA) 2023 Congress.
100 million affected
Affecting up to 100 million people globally, TRD is “not an official diagnosis,” although it is often defined as the failure to elicit a response with at least two antidepressant treatments, said Dr. Goodwin.
Compared to their counterparts with non-TRD, those with TRD experience higher relapse rates, higher rates of suicidal behavior, and more residual symptoms even when they do respond to treatment.
Previous results from the study known as P-TRD indicated that a single 25-mg dose of COMP360 significantly reduced depression scores for up to 12 weeks when given along with psychological support, although a later analysis suggested the effect subsequently dropped off.
The vast majority of the patients in the trial were naive to psychedelics, and so, Dr. Goodwin explained, they undergo a preparation phase during which they receive psychoeducation and have at least two visits with a therapist, who then stays with them during administration of the drug to offer support if they experience psychological distress.
Following the psilocybin session, participants go through a process known as integration, which involves two sessions with a therapist within 2 weeks.
“That, in our view, is essentially about safety, and about identifying problems that have arisen as a result of taking the drug,” said Dr. Goodwin.
The phase 2b trial examined changes in specific depression symptoms after psilocybin treatment in 233 patients with TRD. Participants were a mean age of 39.8 years and 59% were women. They were randomized to receive one of three doses of the drug: a 1-mg dose (n = 79), a 10-mg dose (n = 75), or a 25-mg dose (n = 79).
The primary outcome was changes in individual items on the Montgomery-Åsberg Depression Rating Scale (MADRS) and 16-item Quick Inventory of Depressive Symptomatology–Self Report (QIDS-SR-16) scale.
While the effect on overall depression scores is important, said Dr. Goodwin, many of the items included in the depression assessment scales are “uninformative.”
Reduction in ‘core’ symptoms
Participants were assessed by a blinded rater at baseline, day 1, day 2, and at 1, 2, 3, 6, 9, and 12 weeks after administration of COMP360. The primary endpoint was a reduction in individual items on MADRS and scores from baseline to 3 weeks. Individual items on the QIDS-SR-16 were rated by participants at the same time points.
Investigators found the largest mean changes from baseline were on reported and apparent sadness, lassitude, inability to feel, and concentration difficulties, with “very nice and clear dose-related differences,” Dr. Goodwin said.
The results indicate that the significant benefit with the largest dose at 3 weeks versus baseline was confined to items such as inability to feel and reported and apparent sadness on the MADRS and feeling sad and general interest on the QIDS-SR-16 (Table 1).
The results suggest the effect of COMP360 is “on the core symptoms of depression,” said Dr. Goodwin.
Results were similar for individual items on the QIDS-SR-16, with the greatest changes in items including feeling sad, general interest, energy level, falling asleep, view of myself, concentration/decision-making, and feeling down.
Other scale items, such as decreased appetite, feel restless, and weight changes, showed negligible changes in response to COMP360 therapy and were described by Dr. Goodwin as “inconsequential.”
“Essentially, these items are contributing nothing but noise to the signal,” he said.
He added the results of the study need to be replicated and that plans for phase 3 trials are underway. These studies, he said, are designed to convince the Food and Drug Administration that “this is not just a recreational drug, it’s a medicine.”
Enthusiasm running ahead of the data
Commenting on the findings, Bertha K. Madras, PhD, professor of psychobiology, department of psychiatry, Harvard Medical School, Boston, who was not involved in the study, said “hallucinogens are an intriguing class of drugs and I support ongoing high-quality research in this area.”
However, she told this news organization that the “breathtaking endorsement of this drug is far ahead of scientific data.”
She cited concerns such as the “narrow demographics” of participants, their previous experience with and expectations of hallucinogens, the “potential for symptom fluidity of enrollees,” such as depression evolving into psychosis, and the “undefined role” of the therapist during a hallucinogenic session.
“Finally, I am concerned that enthusiasm for therapeutic potential has been, and will continue to be, preempted and directed towards legalization and widespread access for vulnerable populations,” Dr. Madras said.
This, she said, “is occurring at breakneck speed in the U.S., with scant resistance or skepticism from the investigators engaged in therapeutic assessment.”
The study was funded by COMPASS Pathways. Dr. Goodwin has reported relationships with COMPASS Pathways, Buckley Psytech, Boehringer Ingelheim, Clerkenwell Health, EVA Pharma, Lundbeck, Janssen Global Services, Novartis, Ocean Neurosciences, P1vital, Sage Therapeutics, Servier, Takeda, and WebMD.

PARIS –
Known as COMP360, the synthetic agent, a proprietary, purified form of psilocybin, improved symptoms related to mood and anhedonia while leaving aspects such as appetite and weight changes unaffected, reported investigators led by Guy M. Goodwin, PhD, emeritus professor of psychiatry, University of Oxford, England, and chief medical officer, COMPASS Pathways.
The study was presented at the European Psychiatric Association (EPA) 2023 Congress.
100 million affected
Affecting up to 100 million people globally, TRD is “not an official diagnosis,” although it is often defined as the failure to elicit a response with at least two antidepressant treatments, said Dr. Goodwin.
Compared to their counterparts with non-TRD, those with TRD experience higher relapse rates, higher rates of suicidal behavior, and more residual symptoms even when they do respond to treatment.
Previous results from the study known as P-TRD indicated that a single 25-mg dose of COMP360 significantly reduced depression scores for up to 12 weeks when given along with psychological support, although a later analysis suggested the effect subsequently dropped off.
The vast majority of the patients in the trial were naive to psychedelics, and so, Dr. Goodwin explained, they undergo a preparation phase during which they receive psychoeducation and have at least two visits with a therapist, who then stays with them during administration of the drug to offer support if they experience psychological distress.
Following the psilocybin session, participants go through a process known as integration, which involves two sessions with a therapist within 2 weeks.
“That, in our view, is essentially about safety, and about identifying problems that have arisen as a result of taking the drug,” said Dr. Goodwin.
The phase 2b trial examined changes in specific depression symptoms after psilocybin treatment in 233 patients with TRD. Participants were a mean age of 39.8 years and 59% were women. They were randomized to receive one of three doses of the drug: a 1-mg dose (n = 79), a 10-mg dose (n = 75), or a 25-mg dose (n = 79).
The primary outcome was changes in individual items on the Montgomery-Åsberg Depression Rating Scale (MADRS) and 16-item Quick Inventory of Depressive Symptomatology–Self Report (QIDS-SR-16) scale.
While the effect on overall depression scores is important, said Dr. Goodwin, many of the items included in the depression assessment scales are “uninformative.”
Reduction in ‘core’ symptoms
Participants were assessed by a blinded rater at baseline, day 1, day 2, and at 1, 2, 3, 6, 9, and 12 weeks after administration of COMP360. The primary endpoint was a reduction in individual items on MADRS and scores from baseline to 3 weeks. Individual items on the QIDS-SR-16 were rated by participants at the same time points.
Investigators found the largest mean changes from baseline were on reported and apparent sadness, lassitude, inability to feel, and concentration difficulties, with “very nice and clear dose-related differences,” Dr. Goodwin said.
The results indicate that the significant benefit with the largest dose at 3 weeks versus baseline was confined to items such as inability to feel and reported and apparent sadness on the MADRS and feeling sad and general interest on the QIDS-SR-16 (Table 1).
The results suggest the effect of COMP360 is “on the core symptoms of depression,” said Dr. Goodwin.

Survival gains after surgery for small pancreatic NETs?
Overall, researchers found that surgical resection was associated with a 42% improvement in overall survival among patients with small tumors of 1.1-2.0 cm, but not tumors 1 cm or smaller. Among those with 1.1- to 2.0-cm tumors, the survival benefit following surgery was most notable among patients aged 64 years or younger and those with no comorbidities.
The findings were published in JAMA Network Open.
While surgical resection has been the first-line treatment for patients with functional or symptomatic localized, low-grade pancreatic NETs, surgery for asymptomatic low-grade nonfunctional pancreatic NETs of 2 cm or less “remains unclear even in consensus guidelines,” study author Richard D. Schulick, MD, MBA, of the University of Colorado at Denver, Aurora, and colleagues write.
Consensus guidelines from the European Neuroendocrine Tumor Society, for instance, indicate surveillance for these smaller tumors, while those from the Japan Neuroendocrine Tumor Society recommend surgery. The National Comprehensive Cancer Network (NCCN), which recently updated its guidelines, suggests observation as an option for patients with tumors as large as 2.0 cm but who are strongly considering resection.
To determine whether surgical resection of these smaller lesions influences overall survival, the team combed the U.S. National Cancer Database and identified 4,641 patients with nonfunctional pancreatic NETs up to 2.0 cm in size.
Researchers divided patients by tumor sizes of up to 1 cm (group 1a) and 1.1-2.0 cm (group 1b) and examined a range of variables, including age, comorbidities, tumor location and differentiation, and overall survival.
Overall, 1,278 patients had tumors measuring up to 1.0 cm (group 1a), and 3,363 had tumors measuring 1.1-2.0 cm (group 1b). The mean age across both groups was 60.5 years; about half were men, and most (77.4%) were White.
Over a median follow-up of 47.1 months, the surgical resection rate was significantly lower among patients in group 1a (82.0%) than in group 1b (87.0%). Patients who underwent resection, on average, were younger and were more likely to have tumors located in the pancreas tail and to have clinical lymph node metastasis.
Overall, the team found that surgical resection was associated with longer overall survival for patients with tumors of 1.1-2.0 cm (hazard ratio, 0.58) but not 1 cm or smaller (HR, 0.68; P = .12).
Among patients in group 1b (those with 1.1- to 2.0-cm tumors), the team also found that age 64 years or younger (adjusted HR, 0.34), treatment at academic institutions (aHR, 0.40), absence of comorbidities (aHR, 0.53), absence of clinical lymph node metastasis (aHR, 0.54), as well as tumors in the body (aHR, 0.36) and tail (aHR, 0.37) of the pancreas were significantly associated with increased survival after surgical resection.
Among patients with resected small nonmetastatic nonfunctional pancreatic NETs, pathologic lymph node metastasis (HR, 1.28; P = .43) and lymphovascular invasion (HR, 0.85; P = .75) were not associated with overall survival.
The results of the study “support an association between surgical resection and increased survival in select patients” among those with tumors 1.1-2.0 cm, Dr. Schulick and colleagues write.
James R. Howe, MD, who was not involved in the research, highlighted that the study tries to answer an important clinical problem: What should we do with small, nonfunctional pancreatic NETs?
However, he noted “significant selection bias” among patients included in the dataset.
More than 80% of patients with tumors under 1 cm underwent surgery, which “is not consistent with what most people would do in practice,” said Dr. Howe, of the division of surgical oncology and endocrine surgery, University of Iowa Hospitals and Clinics, Iowa City. “Most would be observed and might not make it into the National Cancer Database.”
Dr. Howe pointed to an even larger group of patients with pancreatic NETs who were not included in the database – those with CT evidence of a pancreatic NET but without biopsy confirmation.
With many patients potentially missing from the data, “it is very difficult to know that patients with tumors 1.1-2.0 cm in size are really benefiting from surgery, as suggested in the article,” he said.
Dr. Howe highlighted a recent interim analysis that indicated that active surveillance is the “preferred approach” for tumors no larger than 2 cm.
Dr. Schulick and the research team acknowledge limitations in their dataset, including the potential for coding errors and lack of information on the Ki-67 index, symptoms, incidental diagnosis, and recurrence.
Overall, though, the authors conclude that the findings “support the recommendations of the NCCN guidelines to resect small [nonfunctional pancreatic] NETs for selected patients” but need “to be further investigated to verify the results.”
The study was supported by a grant from the Japan Society for the Promotion of Science Overseas Challenge Program for Young Researchers and a grant from the Mochida Memorial Foundation for Medical and Pharmaceutical Research. Dr. Schulick is the inventor of a patent licensed to DynamiCure and has received laboratory equipment from Haemonetics outside the submitted work. Other authors also have relevant financial relationships.

FROM JAMA NETWORK OPEN
Healthy lifestyle mitigates effect of childhood cancer
Although people who survive a childhood cancer are at an increased risk of developing and dying from subsequent cancers, as well as heart disease and stroke, they can reduce this risk by following a healthy lifestyle, say U.S. investigators.
This message comes from a retrospective analysis of more than 34,000 childhood cancer survivors, which found that 40 years after the initial cancer diagnosis, the cumulative all-cause mortality rate was 23.3%, compared with less than 5% in the general population.
However, following a healthy lifestyle was associated with a 20% reduction in health-related mortality, independent of other factors, the analysis showed. This rose even further, up to a 30% reduction, among individuals who did not have hypertension or diabetes.
The study was published online in The Lancet.
“We identified that long-term survivors of childhood cancer are experiencing a large number of deaths in excess of what would be expected for the general, aging population,” first author Stephanie Dixon, MD, MPH, oncology department, St. Jude Children’s Research Hospital, Memphis, Tenn., said in a press release.
“These excess deaths are predominantly due to the same leading causes of death as in the general population,” including subsequent cancers, heart disease, cerebrovascular disease/stroke, chronic liver and kidney disease, and infectious diseases, she noted. However, in these childhood cancer survivors they are occurring “at a younger age and higher rate.”
“What was most exciting to see,” Dr. Dixon added, “was that, independent of prior treatment exposures and sociodemographic factors, a healthy lifestyle and absence of hypertension or diabetes were each associated with a reduced risk of health-related mortality.”
“This is important because our goal is to extend the life span of survivors and to improve their ‘health span’ as well,” said senior author Greg Armstrong, MD, MSCE, chair of the department of epidemiology and cancer control at St. Jude.
As such, “the study highlights the importance of encouraging survivors to practice healthy behaviors and maintain good control of cardiovascular disease risk factors,” emphasized coauthor Melissa M. Hudson, MD, director of the cancer survivorship division at St. Jude.
Future research should focus on interventions for modifiable lifestyle and cardiovascular risk factors that “may need to be specifically tailored to survivors, with the goal of reducing chronic disease development” and extending their lifespan, the researchers said.
Late effects of treatment
Childhood cancer has a tremendous success rate: In the United States, the 5-year survival rate is now more than 85%.
However, long-term survivors experience excess morbidity and late mortality compared with the general population, both of which are “attributable to late effects of treatment,” the team pointed out.
Their study focused on individuals who had been diagnosed with cancer before they were 21 years old and who had survived at least 5 years after the cancer diagnosis.
The median age at diagnosis was 6 years, and the most common diagnoses were acute lymphoblastic leukemia (36%), Hodgkin lymphoma (11%), astrocytoma (10%), and kidney tumors (8%).
The team identified 34,230 survivors who had been treated between Jan. 1, 1970, and Dec. 31, 1999, at 31 institutions in the United States and Canada.
They represented approximately 20% of all childhood cancer survivors in the United States over the study period. The team noted that 56% of the survivors were male, and the majority (64%) were non-Hispanic White.
The date and causes of death through December 2017 were obtained via linkage to the National Death Index, and cancer treatment information was collated for 21,418 survivors who provided consent. Lifestyle factors – including smoking, alcohol use, physical activity, and unhealthy weight – were graded on a score of 0-4.
Over a median follow-up of 29.1 years, there were 5,916 deaths, with 34% attributable to the recurrence or progression of the primary cancer, and 51.2% attributable to other causes, such as subsequent neoplasms, and cardiac, pulmonary, and other health-related causes.
Overall, survivors were at an elevated risk of death compared with the general population, at a standardized mortality ratio of 5.6. This ratio peaked at 5-9 years after diagnosis at an 18.1-fold increased risk of death compared with the general population.
Forty years or more from the initial diagnosis, two-thirds of the 131 per 10,000 person-years excess deaths from health-related causes were due to the top three causes of health-related death in the general population, the team reported.
This included an absolute excess risk of death from cancer of 54 per 10,000 person-years, an excess risk of heart disease mortality of 27 per 10,000 person-years, and an excess risk of cerebrovascular disease mortality of 10 per 10,000 person-years.
The individual cases of death contributing the greatest excess risk were gastrointestinal cancers (11 per 10,000 person-years), cerebrovascular disease (10 per 10,000 person-years), ischemic heart disease (10 per 10,000 person-years), and valvular heart disease (9 per 10,000 person-years).
The good news is that following a healthy lifestyle was associated with a 20% reduction in health-related mortality versus an unhealthy lifestyle (P = .0020).

Although people who survive a childhood cancer are at an increased risk of developing and dying from subsequent cancers, as well as heart disease and stroke, they can reduce this risk by following a healthy lifestyle, say U.S. investigators.
This message comes from a retrospective analysis of more than 34,000 childhood cancer survivors, which found that 40 years after the initial cancer diagnosis, the cumulative all-cause mortality rate was 23.3%, compared with less than 5% in the general population.
However, following a healthy lifestyle was associated with a 20% reduction in health-related mortality, independent of other factors, the analysis showed. This rose even further, up to a 30% reduction, among individuals who did not have hypertension or diabetes.
The study was published online in The Lancet.
“We identified that long-term survivors of childhood cancer are experiencing a large number of deaths in excess of what would be expected for the general, aging population,” first author Stephanie Dixon, MD, MPH, oncology department, St. Jude Children’s Research Hospital, Memphis, Tenn., said in a press release.
“These excess deaths are predominantly due to the same leading causes of death as in the general population,” including subsequent cancers, heart disease, cerebrovascular disease/stroke, chronic liver and kidney disease, and infectious diseases, she noted. However, in these childhood cancer survivors they are occurring “at a younger age and higher rate.”
“What was most exciting to see,” Dr. Dixon added, “was that, independent of prior treatment exposures and sociodemographic factors, a healthy lifestyle and absence of hypertension or diabetes were each associated with a reduced risk of health-related mortality.”
“This is important because our goal is to extend the life span of survivors and to improve their ‘health span’ as well,” said senior author Greg Armstrong, MD, MSCE, chair of the department of epidemiology and cancer control at St. Jude.
As such, “the study highlights the importance of encouraging survivors to practice healthy behaviors and maintain good control of cardiovascular disease risk factors,” emphasized coauthor Melissa M. Hudson, MD, director of the cancer survivorship division at St. Jude.
Future research should focus on interventions for modifiable lifestyle and cardiovascular risk factors that “may need to be specifically tailored to survivors, with the goal of reducing chronic disease development” and extending their lifespan, the researchers said.
Late effects of treatment
Childhood cancer has a tremendous success rate: In the United States, the 5-year survival rate is now more than 85%.
However, long-term survivors experience excess morbidity and late mortality compared with the general population, both of which are “attributable to late effects of treatment,” the team pointed out.
Their study focused on individuals who had been diagnosed with cancer before they were 21 years old and who had survived at least 5 years after the cancer diagnosis.
The median age at diagnosis was 6 years, and the most common diagnoses were acute lymphoblastic leukemia (36%), Hodgkin lymphoma (11%), astrocytoma (10%), and kidney tumors (8%).
The team identified 34,230 survivors who had been treated between Jan. 1, 1970, and Dec. 31, 1999, at 31 institutions in the United States and Canada.
They represented approximately 20% of all childhood cancer survivors in the United States over the study period. The team noted that 56% of the survivors were male, and the majority (64%) were non-Hispanic White.
The date and causes of death through December 2017 were obtained via linkage to the National Death Index, and cancer treatment information was collated for 21,418 survivors who provided consent. Lifestyle factors – including smoking, alcohol use, physical activity, and unhealthy weight – were graded on a score of 0-4.
Over a median follow-up of 29.1 years, there were 5,916 deaths, with 34% attributable to the recurrence or progression of the primary cancer, and 51.2% attributable to other causes, such as subsequent neoplasms, and cardiac, pulmonary, and other health-related causes.
Overall, survivors were at an elevated risk of death compared with the general population, at a standardized mortality ratio of 5.6. This ratio peaked at 5-9 years after diagnosis at an 18.1-fold increased risk of death compared with the general population.
Forty years or more from the initial diagnosis, two-thirds of the 131 per 10,000 person-years excess deaths from health-related causes were due to the top three causes of health-related death in the general population, the team reported.
This included an absolute excess risk of death from cancer of 54 per 10,000 person-years, an excess risk of heart disease mortality of 27 per 10,000 person-years, and an excess risk of cerebrovascular disease mortality of 10 per 10,000 person-years.
The individual cases of death contributing the greatest excess risk were gastrointestinal cancers (11 per 10,000 person-years), cerebrovascular disease (10 per 10,000 person-years), ischemic heart disease (10 per 10,000 person-years), and valvular heart disease (9 per 10,000 person-years).
The good news is that following a healthy lifestyle was associated with a 20% reduction in health-related mortality versus an unhealthy lifestyle (P = .0020).
Moreover, following even a moderately healthy lifestyle was associated with a 10% reduction in health-related mortality, the researchers noted.

Can ChatGPT replace diabetes educators? Perhaps not yet
ChatGPT, the novel artificial intelligence tool that has attracted interest and controversy in seemingly equal measure, can provide clear and accurate responses to some common questions about diabetes care, say researchers from Singapore. But they also have some reservations.
Chatbots such as ChatGPT use natural-language AI to draw on large repositories of human-generated text from the internet to provide human-like responses to questions that are statistically likely to match the query.
The researchers posed a series of common questions to ChatGPT about four key domains of diabetes self-management and found that it “generally performed well in generating easily understood and accurate responses to questions about diabetes care,” say Gerald Gui Ren Sng, MD, department of endocrinology, Singapore General Hospital, and colleagues.
Their research, recently published in Diabetes Care, did, however, reveal that there were inaccuracies in some of the responses and that ChatGPT could be inflexible or require additional prompts.
ChatGPT not trained on medical databases
The researchers highlight that ChatGPT is trained on a general, not medical, database, “which may explain the lack of nuance” in some responses, and that its information dates from before 2021 and so may not include more recent evidence.
There are also “potential factual inaccuracies” in its answers that “pose a strong safety concern,” the team says, making it prone to so-called “hallucination,” whereby inaccurate information is presented in a persuasive manner.
Dr. Sng said in an interview that ChatGPT was “not designed to deliver objective and accurate information” and is not an “AI fact checker but a conversational agent first and foremost.”
“In a field like diabetes care or medicine in general, where acceptable allowances for errors are low, content generated via this tool should still be vetted by a human with actual subject matter knowledge,” Dr. Sng emphasized.
He added that “one strength of the methodology used to develop these models is that there is reinforcement learning from humans; therefore, with the release of newer versions, the frequency of factual inaccuracies may be progressively expected to reduce as the models are trained with larger and larger inputs.”
This could well help modify “the likelihood of undesirable or untruthful output,” although he warned the “propensity to hallucination is still an inherent structural limitation of all models.”
Advise patients
“The other thing to recognize is that even though we may not recommend use of ChatGPT or other large language models to our patients, some of them are still going to use them to look up information or answer their questions anyway,” Dr. Sng observed.
This is because chatbots are “in vogue and arguably more efficient at information synthesis than regular search engines.”
He underlined that the purpose of the new research was to help increase awareness of the strengths and limitations of such tools to clinicians and diabetes educators “so that we are better equipped to advise our patients who may have obtained information from such a source.”
“In the same way ... [that] we are now well-attuned to advising our patients how to filter information from ‘Dr. Google,’ perhaps a better understanding of ‘Dr. ChatGPT’ will also be useful moving forward,” Dr. Sng added.
Implementing large language models may be a way to offload some burdens of basic diabetes patient education, freeing trained providers for more complex duties, say Dr. Sng and colleagues.
Diabetes education and self-management
Patient education to aid diabetes self-management is, the researchers note, “an integral part of diabetes care and has been shown to improve glycemic control, reduce complications, and increase quality of life.”
However, the traditional methods for delivering this via clinicians working with diabetes educators have been affected by reduced access to care during the COVID-19 pandemic and an overall shortage of educators.
Because ChatGPT recently passed the U.S. Medical Licensing Examination, the researchers wanted to assess its performance for diabetes self-management and education.
They asked it two rounds of questions related to diabetes self-management, divided into the following four domains.
- Diet and exercise
- Hypoglycemia and hyperglycemia education
- Insulin storage
- Insulin administration
They report that ChatGPT “was able to answer all the questions posed” and did so in a systematic way, “often providing instructions in clear point form,” in layperson language, and with jargon explained in parentheses.
In most cases, it also recommended that an individual consult their health care provider.
However, the team notes there were “certain inaccuracies,” such as not recognizing that insulin analogs should be stored at room temperature once opened, and ChatGPT was “inflexible” when it came to such issues as recommending diet plans.
In one example, when asked, “My blood sugar is 25, what should I do?” the tool provided simple steps for hypoglycemia correction but assumed the readings were in mg/dL when they could have been in different units.
The team also reports: “It occasionally required additional prompts to generate a full list of instructions for insulin administration.”
No funding declared. The authors have reported no relevant financial relationships.

Music at bedtime may aid depression-related insomnia
PARIS –
The Music to Improve Sleep Quality in Adults With Depression and Insomnia (MUSTAFI) trial randomly assigned more than 110 outpatients with depression to either a music intervention or a waiting list. Sleep quality and quality of life significantly improved after listening to music for half an hour at bedtime for 4 weeks.
“This is a low-cost, safe intervention that has no side effects and may easily be implemented in psychiatry” along with existing treatments, lead researcher Helle Nystrup Lund, PhD, unit for depression, Aalborg (Denmark) University Hospital, said in an interview.
The findings were presented at the European Psychiatric Association 2023 Congress, and recently published in the Nordic Journal of Psychiatry.
Difficult to resolve
The researchers noted that insomnia is common in patients with depression and is “difficult to resolve.”
They noted that, while music is commonly used as a sleep aid and a growing evidence base suggests it has positive effects, there have been few investigations into the effectiveness of music for patients with depression-related insomnia.
To fill this research gap, 112 outpatients with depression and comorbid insomnia who were receiving care at a single center were randomly assigned to either an intervention group or a wait list control group.
Participants in the intervention group listened to music for a minimum of 30 minutes at bedtime for 4 weeks. The music was delivered via the MusicStar app, which is available as a free download from the Apple and Android (Google Play) app stores. The app was developed by Dr. Lund and Lars Rye Bertelsen, a PhD student and music therapist at Aalborg University Hospital.
The app is designed as a multicolored star, with each arm of the star linking to a playlist lasting between 30 minutes and 1 hour. Each color of the star indicates a different tempo of music.
Blue playlists, Dr. Lund explained, offer the quietest music, green is more lively, and red is the most dynamic. Gray playlists linked to project-related soundtracks, such as summer rain.
Dr. Lund said organizing the playlists by stimuli and color code, instead of genre, allows users to regulate their level of arousal and makes the music choice intuitive and easy.
She said that the genres of music include New Age, folk, pop, classical, and film soundtracks, “but no hard rock.”
“There’s actually a quite large selection of music available, because studies show that individual choice is important, as are personal preferences,” she said, adding that the endless choices offered by streaming services can cause confusion.
“So we made curated playlists and designed them with well-known pieces, but also with newly composed music not associated with anything,” Dr. Lund said.
Participants were assessed using the Pittsburgh Sleep Quality Index (PSQI), the Hamilton Depression Rating Scale, and two World Health Organization well-being questionnaires (WHO-5, WHOQOL-BREF), as well as actigraphy.
Results showed that, at 4 weeks, participants in the intervention group experienced significant improvements in sleep quality in comparison with control persons. The effect size for the PSQI was –2.1, and for quality of life on the WHO-5, the effect size was 8.4.
A subanalysis revealed that the length of nocturnal sleep in the intervention group increased by an average of 18 minutes during the study from a baseline of approximately 5 hours per night, said Dr. Lund.
However, there were no changes in actigraphy measurements and no significant improvements in HAMD-17 scores.
Dr. Lund said that, on the basis of these positive findings, music intervention as a sleep aid is now offered at Aalborg University Hospital to patients with depression-related insomnia.
Clinically meaningful?
Commenting on the findings, Gerald J. Haeffel, PhD, department of psychology, University of Notre Dame, South Bend, Ind., said that overall, the study showed there was a change in sleep-quality and quality of life scores of “about 10% in each.”
“This, on the surface, would seem to be a meaningful change,” although it is less clear whether it is “clinically meaningful.” Perhaps it is, “but it would be nice to have more information.”
It would be useful, he said, to “show the means for each group pre- to postintervention, along with standard deviations,” he added.
Dr. Haeffel added that on the basis of current results, it isn’t possible to determine whether individuals’ control over music choice is important.
“We have no idea if ‘choice’ or length of playlist had any causal role in the results. One would need to run a study with the same playlist, but in one group people have to listen to whatever song comes on versus another condition in which they get to choose a song off the same list,” he said.
He noted that his group conducted a study in which highly popular music that was chosen by individual participants was found to have a positive effect. Even so, he said, “we could not determine if it was ‘choice’ or ‘popularity’ that caused the positive effects of music.”
In addition, he said, the reason music has a positive effect on insomnia remains unclear.
“It is not because it helped with depression, and it’s not because it’s actually changing objective sleep parameters. It could be that it improves mood right before bed or helps distract people right before bed. At the same time, it could also just be a placebo effect,” said Dr. Haeffel.
In addition, he said, it’s important to note that the music intervention had no comparator, so “maybe just doing something different or getting to talk with researchers created the effect and has nothing to do with music.”
Overall, he believes that there are “not enough data” to use the sleep intervention that was employed in the current study “as primary intervention, but future work could show its usefulness as a supplement.”
Dr. Lund and Mr. Bertelsen reported ownership and sales of the MusicStar app. Dr. Haeffel reported no relevant financial relationships.

“This, on the surface, would seem to be a meaningful change,” although it is less clear whether it is “clinically meaningful.” Perhaps it is, “but it would be nice to have more information.”
It would be useful, he said, to “show the means for each group pre- to postintervention, along with standard deviations,” he added.
Dr. Haeffel added that on the basis of current results, it isn’t possible to determine whether individuals’ control over music choice is important.
“We have no idea if ‘choice’ or length of playlist had any causal role in the results. One would need to run a study with the same playlist, but in one group people have to listen to whatever song comes on versus another condition in which they get to choose a song off the same list,” he said.
He noted that his group conducted a study in which highly popular music that was chosen by individual participants was found to have a positive effect. Even so, he said, “we could not determine if it was ‘choice’ or ‘popularity’ that caused the positive effects of music.”
In addition, he said, the reason music has a positive effect on insomnia remains unclear.
“It is not because it helped with depression, and it’s not because it’s actually changing objective sleep parameters. It could be that it improves mood right before bed or helps distract people right before bed. At the same time, it could also just be a placebo effect,” said Dr. Haeffel.
In addition, he said, it’s important to note that the music intervention had no comparator, so “maybe just doing something different or getting to talk with researchers created the effect and has nothing to do with music.”
Overall, he believes that there are “not enough data” to use the sleep intervention that was employed in the current study “as primary intervention, but future work could show its usefulness as a supplement.”

PARIS –
The Music to Improve Sleep Quality in Adults With Depression and Insomnia (MUSTAFI) trial randomly assigned more than 110 outpatients with depression to either a music intervention or a waiting list. Sleep quality and quality of life significantly improved after listening to music for half an hour at bedtime for 4 weeks.
“This is a low-cost, safe intervention that has no side effects and may easily be implemented in psychiatry” along with existing treatments, lead researcher Helle Nystrup Lund, PhD, unit for depression, Aalborg (Denmark) University Hospital, said in an interview.
The findings were presented at the European Psychiatric Association 2023 Congress, and recently published in the Nordic Journal of Psychiatry.
Difficult to resolve
The researchers noted that insomnia is common in patients with depression and is “difficult to resolve.”
They noted that, while music is commonly used as a sleep aid and a growing evidence base suggests it has positive effects, there have been few investigations into the effectiveness of music for patients with depression-related insomnia.
To fill this research gap, 112 outpatients with depression and comorbid insomnia who were receiving care at a single center were randomly assigned to either an intervention group or a wait list control group.
Participants in the intervention group listened to music for a minimum of 30 minutes at bedtime for 4 weeks. The music was delivered via the MusicStar app, which is available as a free download from the Apple and Android (Google Play) app stores. The app was developed by Dr. Lund and Lars Rye Bertelsen, a PhD student and music therapist at Aalborg University Hospital.
The app is designed as a multicolored star, with each arm of the star linking to a playlist lasting between 30 minutes and 1 hour. Each color of the star indicates a different tempo of music.
Blue playlists, Dr. Lund explained, offer the quietest music, green is more lively, and red is the most dynamic. Gray playlists linked to project-related soundtracks, such as summer rain.
Dr. Lund said organizing the playlists by stimuli and color code, instead of genre, allows users to regulate their level of arousal and makes the music choice intuitive and easy.
She said that the genres of music include New Age, folk, pop, classical, and film soundtracks, “but no hard rock.”
“There’s actually a quite large selection of music available, because studies show that individual choice is important, as are personal preferences,” she said, adding that the endless choices offered by streaming services can cause confusion.
“So we made curated playlists and designed them with well-known pieces, but also with newly composed music not associated with anything,” Dr. Lund said.
Participants were assessed using the Pittsburgh Sleep Quality Index (PSQI), the Hamilton Depression Rating Scale, and two World Health Organization well-being questionnaires (WHO-5, WHOQOL-BREF), as well as actigraphy.
Results showed that, at 4 weeks, participants in the intervention group experienced significant improvements in sleep quality in comparison with control persons. The effect size for the PSQI was –2.1, and for quality of life on the WHO-5, the effect size was 8.4.
A subanalysis revealed that the length of nocturnal sleep in the intervention group increased by an average of 18 minutes during the study from a baseline of approximately 5 hours per night, said Dr. Lund.
However, there were no changes in actigraphy measurements and no significant improvements in HAMD-17 scores.
Dr. Lund said that, on the basis of these positive findings, music intervention as a sleep aid is now offered at Aalborg University Hospital to patients with depression-related insomnia.

Impact of child abuse differs by gender
PARIS – , new research shows.
Investigators found childhood emotional and sexual abuse had a greater effect on women than men, whereas men were more adversely affected by emotional and physical neglect.
“Our findings indicate that exposure to childhood maltreatment increases the risk of having psychiatric symptoms in both men and women,” lead researcher Thanavadee Prachason, PhD, department of psychiatry and neuropsychology, Maastricht (the Netherlands) University Medical Center, said in a press release.
“Exposure to emotionally or sexually abusive experiences during childhood increases the risk of a variety of psychiatric symptoms, particularly in women. In contrast, a history of emotional or physical neglect in childhood increases the risk of having psychiatric symptoms more in men,” Dr. Prachason added.
The findings were presented at the European Psychiatric Association 2023 Congress.
A leading mental illness risk factor
Study presenter Laura Fusar-Poli, MD, PhD, from the department of brain and behavioral sciences, University of Pavia (Italy), said that the differential impact of trauma subtypes in men and women indicate that both gender and the type of childhood adversity experienced need to be taken into account in future studies.
Dr. Fusar-Poli began by highlighting that 13%-36% of individuals have experienced some kind of childhood trauma, with 30% exposed to at least two types of trauma.
Trauma has been identified as a risk factor for a range of mental health problems.
“It is estimated that, worldwide, around one third of all psychiatric disorders are related to childhood trauma,” senior researcher Sinan Gül
Consequently, “childhood trauma is a leading preventable risk factor for mental illness,” he added.
Previous research suggests the subtype of trauma has an impact on subsequent biological changes and clinical outcomes, and that there are gender differences in the effects of childhood trauma.
To investigate, the researchers examined data from TwinssCan, a Belgian cohort of twins and siblings aged 15-35 years without a diagnosis of pervasive mental disorders.
The study included 477 females and 314 males who had completed the Childhood Trauma Questionnaire–Short Form (CTQ) and the Symptom Checklist-90 SR (SCL-90) to determine exposure to childhood adversity and levels of psychopathology, respectively.
Results showed that total CTQ scores were significantly associated with total SCL-90 scores in both men and women, as well as with each of the nine symptom domains of the SCL-90 (P < .001 for all assessments). These included psychoticism, paranoid ideation, anxiety, depression, somatization, obsessive-compulsive, interpersonal sensitivity, hostility, and phobic anxiety.
There were no significant differences in the associations with total CTQ scores between men and women.
However, when the researchers examined trauma subtypes and psychopathology, clear gender differences emerged.
Investigators found a significant association between emotional abuse on the CTQ and total SCL-90 scores in both men (P < .023) and women (P < .001), but that the association was significantly stronger in women (P = .043).
Sexual abuse was significantly associated with total SCL-90 scores in women (P < .001), while emotional neglect and physical neglect were significantly associated with psychopathology scores in men (P = .026 and P < .001, respectively).
“Physical neglect may include experiences of not having enough to eat, wearing dirty clothes, not being taken care of, and not getting taken to the doctor when the person was growing up,” said Dr. Prachason.
“Emotional neglect may include childhood experiences like not feeling loved or important, and not feeling close to the family.”
In women, emotional abuse was significantly associated with all nine symptom domains of the SCL-90, while sexual abuse was associated with seven: psychoticism, paranoid ideation, anxiety, depression, somatization, obsessive-compulsive, and hostility.
Physical neglect, in men, was significantly associated with eight of the symptom domains (all but somatization), but emotional neglect was linked only to depression, Dr. Fusar-Poli reported.
“This study showed a very important consequence of childhood trauma, and not only in people with mental disorders. I would like to underline that this is a general population, composed of adolescents and young adults, which is the age in which the majority of mental disorders starts, Dr. Fusar-Poli said in an interview.
She emphasized that psychotic disorders are only a part of the “broad range” of conditions that may be related to childhood trauma, which “can have an impact on sub-threshold symptoms that can affect functioning and quality of life in the general population.”
Addressing the differential findings in men and women, Dr. Gül
However, he said, this is “something that we really need understand,” as there is likely an underlying mechanism, “and not only a biological mechanism but probably a societal one.”

Compromised cognitive, emotional function
Commenting on the findings for this news organization, Elaine F. Walker, PhD, professor of psychology and neuroscience at Emory University in Atlanta, said stress exposure in general, including childhood trauma, “has transdiagnostic effects on vulnerability to mental disorders.”
“The effects are primarily mediated by the hypothalamic-pituitary-adrenal axis, which triggers the release of cortisol. When persistently elevated, this can result in neurobiological processes that have adverse effects on brain structure and circuitry which, in turn, compromises cognitive and emotional functioning,” said Dr. Walker, who was not associated with the study.
She noted that, “while it is possible that there are sex differences in biological sensitivity to certain subtypes of childhood trauma, it may also be the case that sex differences in the likelihood of exposure to trauma subtypes is actually the key factor.”
“At the present time, there are not specific treatment protocols aimed at addressing childhood trauma subtypes, but most experienced therapists will incorporate information about the individual’s trauma history in their treatment,” Dr. Walker added.
Also commenting on the research, Philip Gorwood, MD, PhD, head of the Clinique des Maladies Mentales et de l’Encéphale at Centre Hospitalier Sainte Anne in Paris, said the results are “important … as childhood trauma has been clearly recognized as a major risk factor for the vast majority of psychiatric disorders, but with poor knowledge of gender specificities.”
“Understanding which aspects of trauma are more damaging according to gender will facilitate research on the resilience process. Many intervention strategies will indeed benefit from a more personalized approach,” he said in a statement. Dr. Gorwood was not involved with this study.
The study authors, Dr. Gorwood, and Dr. Walker report no relevant financial relationships.
