Psoriasis is a chronic multisystemic inflammatory skin disease with a worldwide prevalence of 2% to 3%.¹ Psoriasis can be accompanied by other conditions such as psoriatic arthritis, obesity, metabolic syndrome, diabetes mellitus, hypertension, dyslipidemia, atherosclerotic disease, inflammatory bowel disease, and anxiety/depression. It is important to manage comorbidities of psoriasis in addition to treating the cutaneous manifestations of the disease.¹

Obesity is a major public health concern worldwide. Numerous observational and epidemiologic studies have reported a high prevalence of obesity among patients with psoriasis.² Current evidence indicates that obesity may initiate or worsen psoriasis; furthermore, it is important to note that obesity may negatively impact the effectiveness of psoriasis-specific treatments or increase the incidence of adverse effects. Therefore, managing obesity is crucial in the treatment of psoriasis.³ Numerous studies have investigated the association between psoriasis and obesity, and they commonly conclude that both conditions share the same genetic metabolic pathways.^2-4 However, it is important to consider environmental factors such as dietary habits, smoking, alcohol consumption, and a sedentary lifestyle—all of which are associated with psoriasis and also can contribute to the development of obesity.⁵ Because of the effects of obesity in psoriasis patients, factors that impact the development of obesity have become a popular research topic.

Eating disorders (EDs) are a crucial risk factor for both developing and maintaining obesity. In particular, two EDs that are associated with obesity include binge eating disorder and bulimia nervosa.⁶ According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition,⁷ binge eating disorder can be diagnosed when a patient has at least 1 episode of binge eating per week over a 3-month period. Bulimia nervosa can be diagnosed when a patient is excessively concerned with their body weight and shape and engages in behaviors to prevent weight gain (eg, forced vomiting, excessive use of laxatives).⁷ Psychiatrists who specialize in EDs make diagnoses based on these criteria. In daily practice, there are several quick and simple questionnaires available to screen for EDs that can be used by nonpsychiatrist physicians, including the commonly used 26-item Eating Attitudes Test (EAT-26).⁸ The EAT-26 has been used to screen for EDs in patients with inflammatory disorders.⁹

The aim of this study was to screen for EDs in patients with psoriasis to identify potential risk factors for development of obesity.

Materials and Methods

This study included patients with psoriasis who were screened for EDs at a tertiary dermatology clinic in Turkey between January 2021 and December 2023. This study was approved by the local ethics committee and was in accordance with the Declaration of Helsinki (decision number E-93471371-514.99-225000079).

Study Design and Patient Inclusion Criteria—This quantitative cross-sectional study utilized EAT-26, Dermatology Life Quality Index (DLQI), Attitude Scale for Healthy Nutrition (ASHN), and Depression Anxiety Stress Scale-21 (DASS-21) scores. All the questionnaire scales used in the study were adapted and validated in Turkey.^8,10-12 The inclusion criteria consisted of being older than 18 years of age, being literate, having psoriasis for at least 1 year that was not treated topically or systemically, and having no psychiatric diseases outside an ED. The questionnaires were presented in written format following the clinical examination. Literacy was an inclusion criterion in this study due to the absence of auxiliary health personnel.

Study Variables—The study variables included age, sex, marital status (single/divorced or married), education status (primary/secondary school or high school/university), employment status (employed or unemployed/retired), body mass index (BMI), smoking status, alcohol-consumption status, Psoriasis Area Severity Index score, presence of nail psoriasis and psoriatic arthritis, duration of psoriasis, family history of psoriasis, EAT-26 score, ASHN score, DLQI score, and DASS-21 score. Body mass index was calculated by taking a participant’s weight in kilograms and dividing it by their height in meters squared. The BMI values were classified into 3 categories: normal (18.5–24.9 kg/m²), overweight (25.0–29.9 kg/m²), and obese (≥30 kg/m²).¹³

Questionnaires—The EAT-26 questionnaire includes 26 questions that are used to detect EDs. Responses to each question include Likert-type answer options (ie, “always,” “usually,” “often,” “sometimes,” “rarely,” and “never.”) Patients with scores of 20 points or higher (range, 0–78) are classified as high risk for EDs.⁸ In our study, EAT-26 scores were grouped into 2 categories: patients scoring less than 20 points and those scoring 20 points or higher.

The DLQI questionnaire includes 10 questions to measure dermatologic symptoms and qualiy of life. Responses to each question include Likert-type answer options (ie, “not at all,” “a little,” “a lot,” or “very much.”) On the DLQI scale, the higher the score, the lower the quality of life (score range, 0–30).¹⁰

The ASHN questionnaire includes 21 questions that measure attitudes toward healthy nutrition with 5 possible answer options (“strongly disagree,” “disagree,” “undecided,” “agree,” and “strongly agree”). On this scale, higher scores indicate the participant is more knowledgeable about healthy nutrition (score range, 0–78).¹¹

The DASS-21 questionnaire includes 21 questions that measure the severity of a range of symptoms common to depression, anxiety, and stress. Responses include Likert-type answer options (eg, “never,” “sometimes,” “often,” and “almost always.”) On this scale, a higher score (range of 0–21 for each) indicates higher levels of depression, anxiety, and stress.¹²

Statistical Analysis—Descriptive statistics were analyzed using SPSS software version 22.0 (IBM). The Shapiro-Wilk test was applied to determine whether the data were normally distributed. For categorical variables, frequency differences among groups were compared using the Pearson χ² test. A t test was used to compare the means of 2 independent groups with a normal distribution. One-way analysis of variance and Tukey Honest Significant Difference post hoc analysis were used to test whether there was a statistically significant difference among the normally distributed means of independent groups. Pearson correlation analysis was used to determine whether there was a linear relationship between 2 numeric measurements and, if so, to determine the direction and severity of this relationship. P<.05 indicated statistical significance in this study.

Results

Study Participant Demographics—This study included 82 participants with a mean age of 44.3 years; 52.4% (43/82) were female, and 85.4% (70/82) were married. The questionnaire took an average of 4.2 minutes for participants to complete. A total of 57.3% (47/82) of patients had completed primary/secondary education and 59.8% (49/82) were employed. The mean BMI was 28.1 kg/m². According to the BMI classification, 26.8% (22/82) participants had a normal weight, 36.6% (30/82) were overweight, and 43.9% (36/82) were obese. A total of 48.8% (40/82) of participants smoked, and 4.9% (4/82) consumed alcohol. The mean Psoriasis Area and Severity Index score was 5.4. A total of 54.9% (45/82) of participants had nail psoriasis, and 24.4% (20/82) had psoriatic arthritis. The mean duration of psoriasis was 153 months. A total of 29.3% (24/82) of participants had a positive family history of psoriasis. The mean EAT-26 score was 11.1. A total of 12.2% (10/82) of participants had an EAT-26 score of 20 points or higher and were considered at high risk for an ED. The mean ASHN score was 72.9; the mean DLQI score was 5.5; and on the DASS-21 scale, mean scores for depression, anxiety, and stress were 6.3, 8.7, and 10.0, respectively (Table).

Comparative Evaluation of the BMI Groups—The only statistically significant differences among the 3 BMI groups were related to marital status, EAT-26 score, and anxiety and stress scores (P=.02, <.01, <.01, and <.01, respectively)(eTable 1). The number of single/divorced participants in the overweight group was significantly (P=.02) greater than in the normal weight group. The mean EAT-26 score for the normal weight group was significantly (P<.01) lower than for the overweight and obese groups; there was no significant difference in mean EAT-26 scores between the overweight and obese groups. The mean anxiety score was significantly (P<.01) lower in the normal weight group compared with the overweight and obese groups. There was no significant difference between the overweight and obese groups according to the mean depression score. The mean stress and anxiety scores were significantly (P<.01) lower in the normal weight group than in the overweight and obese groups. There was no significant difference between the overweight and obese groups according to the mean anxiety score.

Comment

Eating disorders are psychiatric conditions that require a multidisciplinary approach. Nonpsychiatric medical departments may be involved due to the severe consequences (eg, various skin changes¹⁴) of these disorders. Psoriasis is not known to be directly affected by the presence of an ED; however, it is possible that EDs could indirectly affect patients with psoriasis by influencing obesity. Therefore, this study aimed to examine the relationship between ED risk factors and obesity in this population.

The relationship between psoriasis and obesity has been a popular research topic in dermatology since the 1990s.¹⁵ Epidemiologic and observational studies have reported that patients with psoriasis are more likely to be overweight or have obesity, which is an independent risk factor for psoriasis.^3,16 However, the causal relationship between psoriasis and obesity remains unclear. In a comprehensive review, Barros et al¹⁷ emphasized the causal relationship between obesity and psoriasis under several headings. Firstly, a higher BMI increases the risk for psoriasis by promoting cytokine release and immune system dysregulation. Secondly, a Western diet (eg, processed foods and fast food) triggers obesity and psoriasis by increasing adipose tissue. Thirdly, the alteration of the skin and gut microbiota triggers chronic inflammation as a result of bacterial translocation in patients with obesity. Fourthly, a high-fat diet and palmitic acid disrupt the intestinal integrity of the gut and increase the risk for psoriasis and obesity by triggering chronic inflammation of bacterial fragments that pass into the blood. Finally, the decrease in the amount of adiponectin and the increase in the amount of leptin in patients with obesity may cause psoriasis by increasing proinflammatory cytokines, which are similar to those involved in the pathogenesis of psoriasis.¹⁷ Additionally, psoriatic inflammation can cause insulin resistance and metabolic dysfunction, leading to obesity.¹⁸ The relationship between psoriasis and obesity cannot be solely explained by metabolic pathways. Smoking, alcohol consumption, and a sedentary lifestyle all are associated with psoriasis and also can contribute to obesity.⁵ Our study revealed no significant difference in smoking or alcohol consumption between the normal weight and overweight/obesity groups. Based on our data, we determined that smoking and alcohol consumption did not affect obesity in our patients with psoriasis.

Observational and epidemiologic studies have shown that patients with psoriasis experience increased rates of depression, anxiety, and stress.¹⁹ In studies of pathogenesis, a connection between depression and psoriatic inflammation has been established.²⁰ It is known that inflammatory cytokines similar to those in psoriasis are involved in the development of obesity.¹⁸ In addition, depression and anxiety can lead to binge eating, unhealthy food choices, and a more sedentary lifestyle.⁵ All of these variables may contribute to the associations between depression and anxiety with psoriasis and obesity. Zafiriou et al²¹ conducted a study to investigate the relationship between psoriasis, obesity, and depression through inflammatory pathways with a focus on the importance of IL-17. Data showing that IL-17–producing Th17-cell subgroups play a considerable role in the development of obesity and depression prompted the authors to suggest that psoriasis, obesity, and ­anxiety/depression may be interconnected manifestations of immune dysregulation, potentially linked to IL-17 and its associated cells.²¹ Mrowietz et al²² also suggested that metabolic inflammation may contribute to obesity and depression in patients with psoriasis and highlighted the importance of several cytokines, including tumor necrosis factor α, IL-6, IL-8, IL-17, and IL-23. Our study revealed no significant differences in depression scores between BMI groups. Another meta-analysis reported conflicting findings on the incidence of depression in obese patients with psoriasis.²³ Some of the studies had a small number of participants. Compared to depression, anxiety has received less attention in studies of patients with obesity with psoriasis. However, these studies have shown a positive correlation between anxiety scores and BMI in patients with psoriasis.^24,25 In our study, similar to the findings of previous studies, overweight patients and those with obesitywho have psoriasis had significantly (P<.01) greater anxiety and stress scores than did normal weight patients with psoriasis.

Obesity should be assessed in patients with psoriasis via a biopsychosocial approach that takes into account genetic, behavioral, and environmental factors.²⁶ Eating disorders are considered to be one of the factors contributing to obesity. Numerous studies in the literature have demonstrated a greater incidence of EDs in patients with obesity vs those without obesity.^5,6,27 Obesity and EDs have a bidirectional relationship: individuals with obesity are at risk for EDs due to body dissatisfaction, dieting habits, and depressive states. Conversely, poor eating behaviors in individuals with a normal weight can lead to obesity.²⁸

There are few studies in the literature exploring the relationship between psoriasis and EDs. Crosta et al²⁹ demonstrated that patients with psoriasis had impaired results on ED screening tests and that these scores deteriorated further as BMI increased. Moreover, Altunay et al³⁰ demonstrated that patients with psoriasis and metabolic syndrome had higher scores on the ED screening test. In this study, patients with higher scores also exhibited high levels of anxiety.³⁰ In our study, similar to the findings of previous studies, patients with psoriasis who were overweight or had obesity had significantly (P<.01) greater EAT-26 scores than those in the normal weight group. Patients with high EAT-26 scores also exhibited elevated levels of depression, anxiety, and stress. Additionally, EAT-26 scores were positively correlated with BMI, anxiety, depression, and stress scores. Our study as well as other studies in the literature indicate that additional research is needed to determine the associations between EDs and obesity in psoriasis.

Conclusion

Managing obesity is crucial for patients with psoriasis. This study showed that EAT-26 scores were higher in patients with psoriasis who were overweight or had obesity than in those who were normal weight. Participants with high EAT-26 scores (≥20 points) were more likely to be female and have higher anxiety and stress scores. In addition, EAT-26 scores were positively correlated with BMI as well as depression, anxiety, and stress scores. Eating disorders may contribute to the development of obesity in patients with psoriasis. Although our study was limited by a small sample size, the results suggest that there is a need for large-scale multicenter studies to investigate the relationship between psoriasis and EDs.

Responses to each question include Likert-type answer options (ie, “not at all,” “a little,” “a lot,” or “very much.”) On the DLQI scale, the higher the score, the lower the quality of life (score range, 0–30).¹⁰

The ASHN questionnaire includes 21 questions that measure attitudes toward healthy nutrition with 5 possible answer options (“strongly disagree,” “disagree,” “undecided,” “agree,” and “strongly agree”). On this scale, higher scores indicate the participant is more knowledgeable about healthy nutrition (score range, 0–78).¹¹

The DASS-21 questionnaire includes 21 questions that measure the severity of a range of symptoms common to depression, anxiety, and stress. Responses include Likert-type answer options (eg, “never,” “sometimes,” “often,” and “almost always.”) On this scale, a higher score (range of 0–21 for each) indicates higher levels of depression, anxiety, and stress.¹²

Statistical Analysis—Descriptive statistics were analyzed using SPSS software version 22.0 (IBM). The Shapiro-Wilk test was applied to determine whether the data were normally distributed. For categorical variables, frequency differences among groups were compared using the Pearson χ² test. A t test was used to compare the means of 2 independent groups with a normal distribution. One-way analysis of variance and Tukey Honest Significant Difference post hoc analysis were used to test whether there was a statistically significant difference among the normally distributed means of independent groups. Pearson correlation analysis was used to determine whether there was a linear relationship between 2 numeric measurements and, if so, to determine the direction and severity of this relationship. P<.05 indicated statistical significance in this study.

Results

Study Participant Demographics—This study included 82 participants with a mean age of 44.3 years; 52.4% (43/82) were female, and 85.4% (70/82) were married. The questionnaire took an average of 4.2 minutes for participants to complete. A total of 57.3% (47/82) of patients had completed primary/secondary education and 59.8% (49/82) were employed. The mean BMI was 28.1 kg/m². According to the BMI classification, 26.8% (22/82) participants had a normal weight, 36.6% (30/82) were overweight, and 43.9% (36/82) were obese. A total of 48.8% (40/82) of participants smoked, and 4.9% (4/82) consumed alcohol. The mean Psoriasis Area and Severity Index score was 5.4. A total of 54.9% (45/82) of participants had nail psoriasis, and 24.4% (20/82) had psoriatic arthritis. The mean duration of psoriasis was 153 months. A total of 29.3% (24/82) of participants had a positive family history of psoriasis. The mean EAT-26 score was 11.1. A total of 12.2% (10/82) of participants had an EAT-26 score of 20 points or higher and were considered at high risk for an ED. The mean ASHN score was 72.9; the mean DLQI score was 5.5; and on the DASS-21 scale, mean scores for depression, anxiety, and stress were 6.3, 8.7, and 10.0, respectively (Table).

Comparative Evaluation of the BMI Groups—The only statistically significant differences among the 3 BMI groups were related to marital status, EAT-26 score, and anxiety and stress scores (P=.02, <.01, <.01, and <.01, respectively)(eTable 1). The number of single/divorced participants in the overweight group was significantly (P=.02) greater than in the normal weight group. The mean EAT-26 score for the normal weight group was significantly (P<.01) lower than for the overweight and obese groups; there was no significant difference in mean EAT-26 scores between the overweight and obese groups. The mean anxiety score was significantly (P<.01) lower in the normal weight group compared with the overweight and obese groups. There was no significant difference between the overweight and obese groups according to the mean depression score. The mean stress and anxiety scores were significantly (P<.01) lower in the normal weight group than in the overweight and obese groups. There was no significant difference between the overweight and obese groups according to the mean anxiety score.

Comment

Eating disorders are psychiatric conditions that require a multidisciplinary approach. Nonpsychiatric medical departments may be involved due to the severe consequences (eg, various skin changes¹⁴) of these disorders. Psoriasis is not known to be directly affected by the presence of an ED; however, it is possible that EDs could indirectly affect patients with psoriasis by influencing obesity. Therefore, this study aimed to examine the relationship between ED risk factors and obesity in this population.

The relationship between psoriasis and obesity has been a popular research topic in dermatology since the 1990s.¹⁵ Epidemiologic and observational studies have reported that patients with psoriasis are more likely to be overweight or have obesity, which is an independent risk factor for psoriasis.^3,16 However, the causal relationship between psoriasis and obesity remains unclear. In a comprehensive review, Barros et al¹⁷ emphasized the causal relationship between obesity and psoriasis under several headings. Firstly, a higher BMI increases the risk for psoriasis by promoting cytokine release and immune system dysregulation. Secondly, a Western diet (eg, processed foods and fast food) triggers obesity and psoriasis by increasing adipose tissue. Thirdly, the alteration of the skin and gut microbiota triggers chronic inflammation as a result of bacterial translocation in patients with obesity. Fourthly, a high-fat diet and palmitic acid disrupt the intestinal integrity of the gut and increase the risk for psoriasis and obesity by triggering chronic inflammation of bacterial fragments that pass into the blood. Finally, the decrease in the amount of adiponectin and the increase in the amount of leptin in patients with obesity may cause psoriasis by increasing proinflammatory cytokines, which are similar to those involved in the pathogenesis of psoriasis.¹⁷ Additionally, psoriatic inflammation can cause insulin resistance and metabolic dysfunction, leading to obesity.¹⁸ The relationship between psoriasis and obesity cannot be solely explained by metabolic pathways. Smoking, alcohol consumption, and a sedentary lifestyle all are associated with psoriasis and also can contribute to obesity.⁵ Our study revealed no significant difference in smoking or alcohol consumption between the normal weight and overweight/obesity groups. Based on our data, we determined that smoking and alcohol consumption did not affect obesity in our patients with psoriasis.

Observational and epidemiologic studies have shown that patients with psoriasis experience increased rates of depression, anxiety, and stress.¹⁹ In studies of pathogenesis, a connection between depression and psoriatic inflammation has been established.²⁰ It is known that inflammatory cytokines similar to those in psoriasis are involved in the development of obesity.¹⁸ In addition, depression and anxiety can lead to binge eating, unhealthy food choices, and a more sedentary lifestyle.⁵ All of these variables may contribute to the associations between depression and anxiety with psoriasis and obesity. Zafiriou et al²¹ conducted a study to investigate the relationship between psoriasis, obesity, and depression through inflammatory pathways with a focus on the importance of IL-17. Data showing that IL-17–producing Th17-cell subgroups play a considerable role in the development of obesity and depression prompted the authors to suggest that psoriasis, obesity, and ­anxiety/depression may be interconnected manifestations of immune dysregulation, potentially linked to IL-17 and its associated cells.²¹ Mrowietz et al²² also suggested that metabolic inflammation may contribute to obesity and depression in patients with psoriasis and highlighted the importance of several cytokines, including tumor necrosis factor α, IL-6, IL-8, IL-17, and IL-23. Our study revealed no significant differences in depression scores between BMI groups. Another meta-analysis reported conflicting findings on the incidence of depression in obese patients with psoriasis.²³ Some of the studies had a small number of participants. Compared to depression, anxiety has received less attention in studies of patients with obesity with psoriasis. However, these studies have shown a positive correlation between anxiety scores and BMI in patients with psoriasis.^24,25 In our study, similar to the findings of previous studies, overweight patients and those with obesitywho have psoriasis had significantly (P<.01) greater anxiety and stress scores than did normal weight patients with psoriasis.

Obesity should be assessed in patients with psoriasis via a biopsychosocial approach that takes into account genetic, behavioral, and environmental factors.²⁶ Eating disorders are considered to be one of the factors contributing to obesity. Numerous studies in the literature have demonstrated a greater incidence of EDs in patients with obesity vs those without obesity.^5,6,27 Obesity and EDs have a bidirectional relationship: individuals with obesity are at risk for EDs due to body dissatisfaction, dieting habits, and depressive states. Conversely, poor eating behaviors in individuals with a normal weight can lead to obesity.²⁸

There are few studies in the literature exploring the relationship between psoriasis and EDs. Crosta et al²⁹ demonstrated that patients with psoriasis had impaired results on ED screening tests and that these scores deteriorated further as BMI increased. Moreover, Altunay et al³⁰ demonstrated that patients with psoriasis and metabolic syndrome had higher scores on the ED screening test. In this study, patients with higher scores also exhibited high levels of anxiety.³⁰ In our study, similar to the findings of previous studies, patients with psoriasis who were overweight or had obesity had significantly (P<.01) greater EAT-26 scores than those in the normal weight group. Patients with high EAT-26 scores also exhibited elevated levels of depression, anxiety, and stress. Additionally, EAT-26 scores were positively correlated with BMI, anxiety, depression, and stress scores. Our study as well as other studies in the literature indicate that additional research is needed to determine the associations between EDs and obesity in psoriasis.

Conclusion

Managing obesity is crucial for patients with psoriasis. This study showed that EAT-26 scores were higher in patients with psoriasis who were overweight or had obesity than in those who were normal weight. Participants with high EAT-26 scores (≥20 points) were more likely to be female and have higher anxiety and stress scores. In addition, EAT-26 scores were positively correlated with BMI as well as depression, anxiety, and stress scores. Eating disorders may contribute to the development of obesity in patients with psoriasis. Although our study was limited by a small sample size, the results suggest that there is a need for large-scale multicenter studies to investigate the relationship between psoriasis and EDs.

“Petechial rash often prompts further investigation into hematological, dermatological, or vasculitis causes. However, if the above investigations are negative and skin biopsy has not revealed a cause, there is a Renaissance-era diagnosis that is often overlooked but is easily investigated and treated,” wrote Andrew Dermawan, MD, and colleagues from Sir Charles Gairdner Hospital in Nedlands, Australia, in BMJ Case Reports. The diagnosis they highlight is scurvy, a disease that has faded from common medical concern but is reemerging, partly because of the rise in bariatric surgery.

Diagnosing Scurvy in the 2020s

In their article, Dermawan and colleagues present the case of a 50-year-old man with a bilateral petechial rash on his lower limbs, without any history of trauma. The patient, who exhibited no infectious symptoms, also had gross hematuria, microcytic anemia, mild neutropenia, and lymphopenia. Tests for autoimmune and hematological diseases were negative, as were abdominal and leg CT scans, ruling out abdominal hemorrhage and vasculitis. Additionally, a skin biopsy showed no causative findings.

The doctors noted that the patient had undergone sleeve gastrectomy, prompting them to inquire about his diet. They discovered that, because of financial difficulties, his diet primarily consisted of processed foods with little to no fruits or vegetables, and he had stopped taking supplements recommended by his gastroenterologist. Further tests revealed a vitamin D deficiency and a severe deficiency in vitamin C. With the diagnosis of scurvy confirmed, the doctors treated the patient with 1000 mg of ascorbic acid daily, along with cholecalciferol, folic acid, and a multivitamin complex, leading to a complete resolution of his symptoms.
 

Risk Factors Then and Now

Scurvy can present with a range of symptoms, including petechiae, perifollicular hemorrhage, ecchymosis, gingivitis, edema, anemia, delayed wound healing, malaise, weakness, joint swelling, arthralgia, anorexia, neuropathy, and vasomotor instability. It can cause mucosal and gastric hemorrhages, and if left untreated, it can lead to fatal bleeding.

Historically known as “sailors’ disease,” scurvy plagued men on long voyages who lacked access to fresh fruits or vegetables and thus did not get enough vitamin C. In 1747, James Lind, a British physician in the Royal Navy, demonstrated that the consumption of oranges and lemons could combat scurvy.

Today’s risk factors for scurvy include malnutrition, gastrointestinal disorders (eg, chronic inflammatory bowel diseases), alcohol and tobacco use, eating disorders, psychiatric illnesses, dialysis, and the use of medications that reduce the absorption of ascorbic acid (such as corticosteroids and proton pump inhibitors).

Scurvy remains more common among individuals with unfavorable socioeconomic conditions. The authors of the study emphasize how the rising cost of living — specifically in Australia but applicable elsewhere — is changing eating habits, leading to a high consumption of low-cost, nutritionally poor foods.

Poverty has always been a risk factor for scurvy, but today there may be an additional cause: bariatric surgery. Patients undergoing these procedures are at a risk for deficiencies in fat-soluble vitamins A, D, E, and K, and if their diet is inadequate, they may also experience a vitamin C deficiency. Awareness of this can facilitate the timely diagnosis of scurvy in these patients.

TOPLINE:

Venetoclax-obinutuzumab combination therapy for untreated chronic lymphocytic leukemia (CLL) shows a 6-year progression-free survival (PFS) rate of 53%. The time-to-next-treatment (TTNT) rate is 65%, with improved quality of life reported by patients.

METHODOLOGY:

• A total of 432 patients with previously untreated CLL and coexisting conditions were enrolled in the study.
• Participants were randomized 1:1 to receive either 12 cycles of venetoclax with 6 cycles of obinutuzumab or 12 cycles of chlorambucil with 6 cycles of obinutuzumab.
• The primary endpoint was PFS, with secondary endpoints including TTNT, overall survival (OS), and adverse events.
• Minimal residual disease was assessed in peripheral blood and bone marrow at the end of treatment and at several follow-up points.
• The study was conducted across multiple centers and was registered with clinical trial identifiers NCT02242942 and EudraCT 2014-001810-24.

TAKEAWAY:

• The 6-year PFS rate was significantly higher in the venetoclax-obinutuzumab group (53%) than in the chlorambucil-obinutuzumab group (21.7%) (P < .0001).
• The TTNT rate was 65.2% in the venetoclax-obinutuzumab group vs 37.1% in the chlorambucil-obinutuzumab group (P < .0001).
• The OS rate at 6 years was 78.7% in the venetoclax-obinutuzumab group and 69.2% in the chlorambucil-obinutuzumab group (P = .052).
• Patients in the venetoclax-obinutuzumab group reported better quality of life and less fatigue than those in the chlorambucil-obinutuzumab group.

IN PRACTICE:

“Patients treated with the venetoclax-obinutuzumab combination showed a statistically significant sustained prolongation of PFS, compared with patients treated with chlorambucil-obinutuzumab (76.2 vs 36.4 months). Overall, the PFS rate was 53% in the venetoclax-obinutuzumab group vs 21.7% after chlorambucil-obinutuzumab,” the study’s authors wrote.

In a related article, Silvia Deaglio, University of Turin in Italy, noted: “A second important observation of the study is that in the venetoclax-obinutuzumab arm, patients who relapsed more frequently presented with unmutated IGHV genes, deletion of 17p, or TP53 mutations.”

LIMITATIONS:

This study’s limitations included the relatively small sample size and the short duration of follow-up for some endpoints. Additionally, the study population was limited to older adult patients with coexisting conditions, which may limit the generalizability of the findings to a broader CLL population.

DISCLOSURES:

This study was supported by F. Hoffmann-La Roche and AbbVie. Al-Sawaf disclosed receiving grants from BeiGene, AbbVie, Janssen, and Roche. Additional disclosures are noted in the original article.

TOPLINE:

Higher plasma levels of omega-6 and omega-3 fatty acids are associated with a lower incidence of cancer. However, omega-3 fatty acids are linked to an increased risk for prostate cancer, specifically.

METHODOLOGY:

• Researchers looked for associations of plasma omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) with the incidence of cancer overall and 19 site-specific cancers in the large population-based prospective UK Biobank cohort.
• They included 253,138 participants aged 37-73 years who were followed for an average of 12.9 years, with 29,838 diagnosed with cancer.
• Plasma levels of omega-3 and omega-6 fatty acids were measured using nuclear magnetic resonance and expressed as percentages of total fatty acids.
• Participants with cancer diagnoses at baseline, those who withdrew from the study, and those with missing data on plasma PUFAs were excluded.
• The study adjusted for multiple covariates, including age, sex, ethnicity, socioeconomic status, lifestyle behaviors, and family history of diseases.

TAKEAWAY:

• Higher plasma levels of omega-6 and omega-3 fatty acids were associated with a 2% and 1% reduction in overall cancer risk per SD increase, respectively (P = .001 and P = .03).
• Omega-6 fatty acids were inversely associated with 14 site-specific cancers, whereas omega-3 fatty acids were inversely associated with five site-specific cancers.
• Prostate cancer was positively associated with omega-3 fatty acids, with a 3% increased risk per SD increase (P = .049).
• A higher omega-6/omega-3 ratio was associated with an increased risk for overall cancer, and three site-specific cancers showed positive associations with the ratio. “Each standard deviation increase, corresponding to a 13.13 increase in the omega ratio, was associated with a 2% increase in the risk of rectum cancer,” for example, the authors wrote.

IN PRACTICE:

“Overall, our findings provide support for possible small net protective roles of omega-3 and omega-6 PUFAs in the development of new cancer incidence. Our study also suggests that the usage of circulating blood biomarkers captures different aspects of dietary intake, reduces measurement errors, and thus enhances statistical power. The differential effects of omega-6% and omega-3% in age and sex subgroups warrant future investigation,” wrote the authors of the study.

SOURCE:

The study was led by Yuchen Zhang of the University of Georgia in Athens, Georgia. It was published online in the International Journal of Cancer.

LIMITATIONS:

The study’s potential for selective bias persists due to the participant sample skewing heavily toward European ancestry and White ethnicity. The number of events was small for some specific cancer sites, which may have limited the statistical power. The study focused on total omega-3 and omega-6 PUFAs, with only two individual fatty acids measured.

TOPLINE:

Higher plasma levels of omega-6 and omega-3 fatty acids are associated with a lower incidence of cancer. However, omega-3 fatty acids are linked to an increased risk for prostate cancer, specifically.

METHODOLOGY:

• Researchers looked for associations of plasma omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) with the incidence of cancer overall and 19 site-specific cancers in the large population-based prospective UK Biobank cohort.
• They included 253,138 participants aged 37-73 years who were followed for an average of 12.9 years, with 29,838 diagnosed with cancer.
• Plasma levels of omega-3 and omega-6 fatty acids were measured using nuclear magnetic resonance and expressed as percentages of total fatty acids.
• Participants with cancer diagnoses at baseline, those who withdrew from the study, and those with missing data on plasma PUFAs were excluded.
• The study adjusted for multiple covariates, including age, sex, ethnicity, socioeconomic status, lifestyle behaviors, and family history of diseases.

TAKEAWAY:

• Higher plasma levels of omega-6 and omega-3 fatty acids were associated with a 2% and 1% reduction in overall cancer risk per SD increase, respectively (P = .001 and P = .03).
• Omega-6 fatty acids were inversely associated with 14 site-specific cancers, whereas omega-3 fatty acids were inversely associated with five site-specific cancers.
• Prostate cancer was positively associated with omega-3 fatty acids, with a 3% increased risk per SD increase (P = .049).
• A higher omega-6/omega-3 ratio was associated with an increased risk for overall cancer, and three site-specific cancers showed positive associations with the ratio. “Each standard deviation increase, corresponding to a 13.13 increase in the omega ratio, was associated with a 2% increase in the risk of rectum cancer,” for example, the authors wrote.

IN PRACTICE:

“Overall, our findings provide support for possible small net protective roles of omega-3 and omega-6 PUFAs in the development of new cancer incidence. Our study also suggests that the usage of circulating blood biomarkers captures different aspects of dietary intake, reduces measurement errors, and thus enhances statistical power. The differential effects of omega-6% and omega-3% in age and sex subgroups warrant future investigation,” wrote the authors of the study.

The study was led by Yuchen Zhang of the University of Georgia in Athens, Georgia. It was published online in the International Journal of Cancer.

LIMITATIONS:

The study’s potential for selective bias persists due to the participant sample skewing heavily toward European ancestry and White ethnicity. The number of events was small for some specific cancer sites, which may have limited the statistical power. The study focused on total omega-3 and omega-6 PUFAs, with only two individual fatty acids measured. Future studies are needed to examine the roles of other individual PUFAs and specific genetic variants.

TOPLINE:

Patients treated for prostate cancer had higher rates of complications, including urinary and sexual issues, than a control group of men. Radiotherapy increases the risk for bladder cancer and radiation-specific complications, according to the new cohort study.
 

METHODOLOGY:

• Researchers conducted a cohort study to try to characterize long-term treatment-related adverse effects and complications in patients treated for prostate cancer, compared with a general population of older males.
• They used data from the Prostate Cancer Prevention Trial and the Selenium and Vitamin E Cancer Prevention Trial, linked with Medicare claims. A total of 29,196 participants were included in the study’s control group. Of 3946 patients diagnosed with prostate cancer, 655 were treated with prostatectomy, and 1056 were treated with radiotherapy.
• Participants were followed for a median of 10.2 years, with specific follow-up durations being 10.5 years and 8.5 years for the prostatectomy and radiotherapy groups, respectively.
• The study analyzed ten potential treatment-related complications using Medicare claims data, including urinary incontinence, erectile dysfunction, and secondary cancers. 
• Multivariable Cox regression was used to adjust for age, race, and year of time-at-risk initiation, with stratification by study and intervention arm. 

TAKEAWAY:

• At 12 years, there was a 7.23 increase in hazard risk for urinary or sexual complications for patients who had prostatectomy, compared with controls (P < .001).
• Radiotherapy-treated patients had a nearly three times greater hazard risk for bladder cancer and a 100-fold increased hazard risk for radiation-specific complications, such as radiation cystitis and radiation proctitis (P < .001).
• The incidence of any treatment-related complication per 1000 person-years was 124.26 for prostatectomy, 62.15 for radiotherapy, and 23.61 for untreated participants.
• The authors stated that these findings highlight the importance of patient counseling before prostate cancer screening and treatment.

IN PRACTICE:

“We found that, after accounting for baseline population rates, most patients with PCA undergoing treatment experience complications associated with worse quality of life and/or new health risks. The magnitude of these risks, compared with the relatively small benefit found by randomized clinical trials of PCA screening and treatment, should be explicitly reflected in national cancer screening and treatment guidelines and be integral to shared decision-making with patients before initiation of PSA screening, biopsy, or PCA treatment,” wrote the authors of the study.
 

SOURCE:

The study was led by Joseph M. Unger, PhD, SWOG Statistics and Data Management Center, Fred Hutchinson Cancer Center in Seattle, Washington. It was published online on November 7, 2024, in JAMA Oncology.
 

LIMITATIONS:

The study did not account for multiple comparisons, which may affect the statistical significance of some findings. Claims data are subject to misclassification and may underreport complications that are not reported to a physician. The study did not differentiate among strategies of prostatectomy or radiotherapy, which may result in different patterns of complications. The cohort comprised men enrolled in large, randomized prevention trials, which may limit the generalizability of the incidence estimates. Confounding by unknown factors cannot be ruled out, affecting the attribution of risks to prostate cancer treatment alone.

Many patients with Crohn’s disease (CD) have a heightened immune response to flagellins expressed by commensal gut bacteria Lachnospiraceae, with seroreactivity appearing up to 5 years prior to development of Crohn’s complications, according to investigators.

These findings suggest that the flagellin cytometric bead array used in the present study could serve as a simple diagnostic and prognostic tool for patients with CD, and point to a new therapeutic target, lead author Qing Zhao, MD, PhD, of the University of Alabama at Birmingham, and colleagues reported.

Qing Zhao

Previously, Zhao and colleagues found that about 30% of patients with CD had elevated IgG responses to multiple Lachnospiraceae flagellins, and stronger reactivity was associated with higher flagellin-specific CD4+ T cells in circulation.

“In this study, we aimed to identify immunodominant B cell peptide epitopes shared among Lachnospiraceae bacterial flagellins in patients with CD and to correlate this immune reactivity with the clinical disease course,” the investigators wrote in Gastroenterology.

To this end, the investigators analyzed serum samples from adult CD patients, pediatric CD patients, and healthy infants without inflammatory bowel disease, with data derived from multiple sources. Adult patients with CD were part of a regional cohort recruited at the University of Alabama at Birmingham, while pediatric patients with CD came from the RISK Stratification Study, a multisite cohort study across the United States and Canada. Samples from healthy infants were collected from three diverse geographic locations: Uganda, Sweden, and the United States, providing a broad comparison of immune responses to Lachnospiraceae flagellin across populations.

Samples were analyzed via two main methods: a flagellin peptide microarray and a cytometric bead array. The microarray, comprising sequential Lachnospiraceae-derived peptides, enabled identification of IgG responses specific to individual bacterial peptides. The cytometric bead array allowed for multiplexed detection of IgG, IgA, and IgM antibodies to these peptides, quantifying immune reactivity and enabling correlation with clinical disease data.

This approach revealed that nearly half of patients with CD — both adults and children — had a strong IgG immune response targeting a specific bacterial peptide in the Lachnospiraceae flagellin hinge region. This response was linked to an increased risk of disease complications over time, suggesting the peptide’s potential as a biomarker for CD severity and progression, according to the investigators.

Of note, healthy infants also exhibited an elevated IgG response to the same bacterial peptide at around 1 year of age, but this response declined as they grew older, in contrast to its persistence in CD patients. This difference points to a possible failure in immune tolerance in CD, where the natural immune response to gut bacteria in infancy may become dysregulated, Zhao and colleagues explained.

“The flagellin cytometric bead array used in this study holds potential for a simplified yet robust diagnostic and prognostic assay for Crohn’s disease,” they concluded. “Given that reactivity to the dominant flagellin epitope is strongly associated with the development of disease complications, this technique may also assist in identifying patients with Crohn’s disease who would benefit from early therapy.”

Zhao and colleagues also called for future studies to characterize the role of flagellin hinge peptide–specific IgG antibodies in CD pathogenesis, and to explore the hinge peptide as a potential therapeutic target.The study was supported by a Synergy Award from the Kenneth Rainin Foundation, a Career Development Award from the Crohn’s and Colitis Foundation, and grants from the Department of Veterans Affairs, National Institute of Allergy and Infectious Diseases, National Institutes of Health, and National Institute of Diabetes and Digestive and Kidney Diseases. One coauthor and the University of Alabama at Birmingham hold a patent on Lachnospiraceae A4 Fla2, licensed for clinical application by Prometheus Laboratories. Four study coauthors have filed a patent for the flagellin peptide cytometric bead array. One coauthor serves as the founder and chief scientific officer of ImmPrev Bio, a company developing an antigen-directed immunotherapy for Crohn’s disease.

On September 27, 2024, UMC Health System in Lubbock, Texas, experienced an IT outage because of a cybersecurity incident that temporarily diverted patients to other healthcare facilities. So far, in 2024, there have been 386 cyberattacks on healthcare organizations. These high-impact ransomware attacks disrupt and delay patient care.

In recent years, many healthcare systems, including Scripps Health, Universal Health Services, Vastaamo, Sky Lakes, and the University of Vermont, have paid millions — even tens of millions — to recover data after a cyberattack or data breach. When healthcare systems come under cyber fire, the impact extends far past disrupting workflows and compromising data, patient safety can be also be compromised, vital information may be lost, and imaging and lab results can go missing or be held for ransom, making physicians’ job difficult or impossible.

In fact, cyberattacks on hospitals are far more common than you may realize. A new report issued by Ponemon and Proofpoint found that 92% of healthcare organizations have experienced a cyberattack in the past 12 months. Even more sobering is that about half of the organizations affected suffered disruptions in patient care.
 

Healthcare Systems = ‘Soft Targets’

Healthcare systems are a “soft target” for hackers for several reasons, pointed out Matthew Radolec, vice president, incident response and cloud operations at Varonis, a data security company. “One, they’re usually an amalgamation of many healthcare systems that are interconnected,” said Radolec. “A lot of hospitals are connected to other hospitals or connected to educational institutions, which means their computer vulnerabilities are shared ... and if they have an issue, it could very easily spread to your network.”

Another factor is the cost of securing data. “[With hospitals], they’ll say that a dollar spent on security is a dollar not spent on patient care,” said Radolec. “So the idea of investing in security is really tough from a budget standpoint…they’re choosing between a new MRI machine or better antivirus, backups, or data security.”

Because of the wealth of private data and healthcare information they maintain, hospitals are considered “high impact” for cybercriminals. Attackers know that if they get a foothold in a hospital, it’s more likely to pay — and pay quickly, Radolec told this news organization. Hospitals are also likely to have cyber insurance to help cover the cost of having their data stolen, encrypted, and ransomed.

The 2024 Microsoft Digital Defense Report also found that the bad actors are more sophisticated and better resourced and can challenge even the best cybersecurity. Improved defenses may not be good enough, and the sheer volume of attacks must be met with effective deterrence and government solutions that impose consequences for cybercriminals.
 

Vulnerable Users

Whether through a phishing email or text, password attack, or web attack, “the moment a ‘threat actor’ gets into your institution and gets credentials ... that’s the Nirvana state of a threat actor,” warned Ryan Witt, chair of the healthcare customer advisory board and vice president of Industry Solutions at Proofpoint, a cybersecurity platform. “They have those credentials and will go into deep reconnaissance mode. It often takes healthcare up to 6 months to even ascertain whether somebody’s actually in the network.” During that time, the hacker is learning how the institution works, what job functions matter, and how best to plan their attack.

“Attackers are getting in because they’re buying databases of usernames and passwords. And they’re trying them by the millions,” added Radolec. “For a sophisticated actor, all it takes is time and motivation. They have the skills. It’s just a matter of how persistent they want to be.”

Certain hospital staff are also more likely to be targeted by cyberhackers than others. “About 10% of a healthcare organization’s user base is much more vulnerable for all sorts of reasons — how they work, the value of their job title and job function, and therefore their access to systems,” said Witt.

High-profile staff are more likely to be targeted than those in lower-level positions; the so-called “CEO attack” is typical. However, staff in other hospital departments are also subject to cybercriminals, including hospice departments/hospice organizations and research arms of hospitals.
 

The Impact of Cyberattacks on Patients 

Physicians and healthcare execs may have considered cybersecurity more of a compliance issue than a true threat to patients in the past. But this attitude is rapidly changing. “We are starting to see a very clear connection between a cyber event and how it can impact patient care and patient safety,” said Witt.

According to the Proofpoint report, cyber breaches can severely affect patient care. In 2024:

• 56% of respondents saw a delay in patient tests/procedures
• 53% experienced increased patient complications from medical procedures
• 52% noted a longer patient length of stay
• 44% saw an increase in patient transfers to other facilities
• 28% had an increase in mortality rate

What Hospitals and Physicians Can Do

Fortunately, hospitals can take measures to better protect their data and their patients. One strategy is segmenting networks to reduce the amount of data or systems one person or system can access. Educating staff about the dangers of phishing and spoofing emails also help protect organizations from ransomware attacks. Having staff avoid reusing passwords and updating logins and passwords frequently helps.

Most hospitals also need more robust security controls. Physicians and healthcare facilities must also embrace the cybersecurity controls found in other industries, said Witt. “Multifactor authentication is one of those things that can cause us frustration,” he said. “The controls can seem onerous, but they’re really valuable overall…and should become standard practice.”

Doctors can also prepare for a ransomware attack and protect patients by practicing some “old-school” medicine, like using paper systems and maintaining good patient notes — often, those notes are synced locally as well as offsite, so you’d be able to access them even during a data breach. “It’s smart to write prescriptions on pads sometimes,” said Radolec. “Don’t forget how to do those things because that will make you more resilient in the event of a ransomware attack.”
 

A Continuing Threat

Cyberattacks will continue. “When you look at the high likelihood [of success] and the soft target, you end up with ... a perfect storm,” said Radolec. “Hospitals have a lot of vulnerabilities. They have to keep operations going just to receive income, but also to deliver care to people.”

That means that the burden is on healthcare organizations — including physicians, nurses, staff, and C-level execs — to help keep the “security” in cybersecurity. “We are all part of the cybersecurity defense,” said Witt. Helping to maintain that defense has become a critical aspect of caring for patients.

On September 27, 2024, UMC Health System in Lubbock, Texas, experienced an IT outage because of a cybersecurity incident that temporarily diverted patients to other healthcare facilities. So far, in 2024, there have been 386 cyberattacks on healthcare organizations. These high-impact ransomware attacks disrupt and delay patient care.

In recent years, many healthcare systems, including Scripps Health, Universal Health Services, Vastaamo, Sky Lakes, and the University of Vermont, have paid millions — even tens of millions — to recover data after a cyberattack or data breach. When healthcare systems come under cyber fire, the impact extends far past disrupting workflows and compromising data, patient safety can be also be compromised, vital information may be lost, and imaging and lab results can go missing or be held for ransom, making physicians’ job difficult or impossible.

In fact, cyberattacks on hospitals are far more common than you may realize. A new report issued by Ponemon and Proofpoint found that 92% of healthcare organizations have experienced a cyberattack in the past 12 months. Even more sobering is that about half of the organizations affected suffered disruptions in patient care.
 

Healthcare Systems = ‘Soft Targets’

Healthcare systems are a “soft target” for hackers for several reasons, pointed out Matthew Radolec, vice president, incident response and cloud operations at Varonis, a data security company. “One, they’re usually an amalgamation of many healthcare systems that are interconnected,” said Radolec. “A lot of hospitals are connected to other hospitals or connected to educational institutions, which means their computer vulnerabilities are shared ... and if they have an issue, it could very easily spread to your network.”

Another factor is the cost of securing data. “[With hospitals], they’ll say that a dollar spent on security is a dollar not spent on patient care,” said Radolec. “So the idea of investing in security is really tough from a budget standpoint…they’re choosing between a new MRI machine or better antivirus, backups, or data security.”

Because of the wealth of private data and healthcare information they maintain, hospitals are considered “high impact” for cybercriminals. Attackers know that if they get a foothold in a hospital, it’s more likely to pay — and pay quickly, Radolec told this news organization. Hospitals are also likely to have cyber insurance to help cover the cost of having their data stolen, encrypted, and ransomed.

The 2024 Microsoft Digital Defense Report also found that the bad actors are more sophisticated and better resourced and can challenge even the best cybersecurity. Improved defenses may not be good enough, and the sheer volume of attacks must be met with effective deterrence and government solutions that impose consequences for cybercriminals.
 

Vulnerable Users

Whether through a phishing email or text, password attack, or web attack, “the moment a ‘threat actor’ gets into your institution and gets credentials ... that’s the Nirvana state of a threat actor,” warned Ryan Witt, chair of the healthcare customer advisory board and vice president of Industry Solutions at Proofpoint, a cybersecurity platform. “They have those credentials and will go into deep reconnaissance mode. It often takes healthcare up to 6 months to even ascertain whether somebody’s actually in the network.” During that time, the hacker is learning how the institution works, what job functions matter, and how best to plan their attack.

“Attackers are getting in because they’re buying databases of usernames and passwords. And they’re trying them by the millions,” added Radolec. “For a sophisticated actor, all it takes is time and motivation. They have the skills. It’s just a matter of how persistent they want to be.”

Certain hospital staff are also more likely to be targeted by cyberhackers than others. “About 10% of a healthcare organization’s user base is much more vulnerable for all sorts of reasons — how they work, the value of their job title and job function, and therefore their access to systems,” said Witt.

High-profile staff are more likely to be targeted than those in lower-level positions; the so-called “CEO attack” is typical. However, staff in other hospital departments are also subject to cybercriminals, including hospice departments/hospice organizations and research arms of hospitals.
 

The Impact of Cyberattacks on Patients 

Physicians and healthcare execs may have considered cybersecurity more of a compliance issue than a true threat to patients in the past. But this attitude is rapidly changing. “We are starting to see a very clear connection between a cyber event and how it can impact patient care and patient safety,” said Witt.

According to the Proofpoint report, cyber breaches can severely affect patient care. In 2024:

• 56% of respondents saw a delay in patient tests/procedures
• 53% experienced increased patient complications from medical procedures
• 52% noted a longer patient length of stay
• 44% saw an increase in patient transfers to other facilities
• 28% had an increase in mortality rate

What Hospitals and Physicians Can Do

Fortunately, hospitals can take measures to better protect their data and their patients. One strategy is segmenting networks to reduce the amount of data or systems one person or system can access. Educating staff about the dangers of phishing and spoofing emails also help protect organizations from ransomware attacks. Having staff avoid reusing passwords and updating logins and passwords frequently helps.

Most hospitals also need more robust security controls. Physicians and healthcare facilities must also embrace the cybersecurity controls found in other industries, said Witt. “Multifactor authentication is one of those things that can cause us frustration,” he said. “The controls can seem onerous, but they’re really valuable overall…and should become standard practice.”

Semaglutide use is associated with an increased risk of retained solid gastric contents, but colonoscopy prep appears to mitigate this issue, according to investigators.

These findings suggest that patients taking GLP-1 receptor agonists (GLP-1RAs) may benefit from a 24-hour liquid fast before anesthetic procedures without the need for a medication hold, reported lead author Haarika Korlipara, MD, of NewYork–Presbyterian/Weill Cornell Medical Center, New York, and colleagues.

“[T]he effects of delayed gastric emptying in patients on long-acting GLP-1RAs are clinically important in the management of anesthetized patients, who may develop periprocedural complications in the setting of retained solid gastric contents,” the investigators wrote in Techniques and Innovations in Gastrointestinal Endoscopy.

NewYork-Presbyterian/Weill Cornell Medical Center

The researchers retrospectively analyzed clinical data from 1,212 patients undergoing upper endoscopy at a tertiary care center. Among them, 602 were on semaglutide for more than four weeks, while 610 were controls not taking the medication.

The primary outcome was the presence of retained solid gastric contents. Secondary outcomes included the need for intubation, early procedure termination, and recommendations for repeat endoscopy.

Semaglutide use was an independent predictor of retained solid gastric contents (odds ratio [OR], 4.74; 95% CI, 2.40-9.35; P less than .0001). Multivariable propensity-matched analysis showed a 6% absolute increase in retained gastric contents in the semaglutide group compared to controls (P less than .0001).

This increase appeared clinically relevant, as semaglutide use was associated with a higher rate of early procedure termination (OR, 3.09; P = 0.02) and recommendations for repeat endoscopies (OR, 3.61; P = 0.02), “indicating the degree of retained solid gastric contents was enough to limit the intended gastric mucosal examination,” the investigators wrote.

However, patients who underwent same-day colonoscopy, which included a 24-hour clear liquid fast leading up to the procedure, were less likely to have retained gastric contents (OR, 0.41; 95% CI, 0.23-0.73; P = 0.003), suggesting that extended fasting protocols may mitigate the risk of procedural complications.

“Patients with a history of gastroparesis are often advised to stop ingesting solid foods and maintain a clear liquid diet for a longer period than standard ASA guidance before anesthetized procedures,” Dr. Korlipara and colleagues wrote. “In our opinion, this recommendation should be considered in patients on long-term GLP-1RA therapy, in response to the findings reported in this study and others about the protective effects of a 24-hour liquid fast.”

Point-of-care gastric ultrasound may also be considered to evaluate patients at higher risk of retained stomach contents, they added, especially in patients with additional risk factors for delayed gastric emptying.

“Previously published data have linked prolonged gastric emptying delays in patients chronically using these medications,” they wrote. “Considering the effect on blood sugar and associated procedural risk, especially in patients taking this medication for diabetes management, more studies are warranted to determine the effect of medication on periprocedural complications and recommend repeat evaluation.”

After this study was released, new clinical guidance on the use of GLP-1RAs before surgery was co-published by AGA and four other societies. The guidance notes that, in most cases, patients can continue to take GLP-1RAs, but individual risk factors for complications should be assessed prior to surgery. The guidance cautions that patients at high risk for significant GI side effects should follow a liquid diet for 24 hours before a procedure and the anesthesia plan be adjusted accordingly. In rare cases, the procedure should be delayed.

Dr. Korlipara disclosed no conflicts of interest.

Although a 2019 World Health Organization (WHO) report concluded that microplastics in drinking water posed no risk to human health, accumulating evidence is beginning to challenge these findings.

Since plastics became widely used in the mid-20th century, they have evolved from a novel substance to an essential component in countless applications, with global production reaching 368 million tons in 2019 and expected to double by 2039. The production and degradation of plastics involve physical, chemical, and biological processes, leading to the formation of tiny fragments known as microplastics (MPs) and nanoplastics (NPs), which accumulate in the environment. Beyond the well-documented environmental harms of MPs and NPs, growing evidence of their presence within the human body raises concerns about their potential to trigger various harmful biological processes. Their detection in the urinary tract and their potential links to kidney and bladder diseases, as shown in animal studies, are particularly alarming.
 

Impacts Becoming Apparent

As the impact of plastic pollution becomes increasingly apparent, the need for standardized international definitions of MPs and NPs is pressing. Government publications reveal notable discrepancies between organizations in defining these fragmented plastics. The lack of consensus among regulatory bodies highlights the challenges in mitigating the environmental and health impacts of MPs and NPs. The International Organization for Standardization offers the most precise classification, defining MPs as solid, insoluble plastic particles ranging from 1 µm to 1 mm and NPs as particles smaller than 1 µm.

The intrusion of MPs and NPs into the human body, whether through inhalation, ingestion, or skin exposure (via wounds, hair follicles, or sweat glands), has been linked to harmful biological effects, including inflammation, alterations in cellular metabolism, physical cellular damage, and reduced cell viability.
 

Urinary Tract Plastics

The detection of MPs and NPs in the human urinary tract, combined with limited understanding of their effects, is a growing concern. An exploratory study published earlier this year aimed to systematically summarize the existing literature regarding the presence of MPs and NPs in the urinary tract and their potential consequences, guided by these research questions:

• What are the characteristics of the plastics detected in the human urinary tract?
• How are MPs and NPs defined in the current literature?
• What methodologies are used to explore the presence and effects of MPs and NPs?
• What are the pathophysiologic consequences of the presence of MPs and NPs in the human urinary tract?

For this study, the “urinary tract” included the kidneys, bladder, ureter, urethra, and urine. By focusing on the urinary tract, the study aimed to consolidate current understanding of MPs and NPs, raise awareness of this emerging issue, and lay the groundwork for further research that could contribute to public health policies and clinical practice guidelines.

The researchers conducted a scoping literature review following the recommendations of the JBI [formerly known as the Joanna Briggs Institute). They systematically searched five databases — PubMed, Scopus, CINAHL, Web of Science, and Embase — as well as gray literature sources.
 

Concerning Study Results

Eighteen articles were identified. The authors represent seven countries: Pakistan (n = 1), the Netherlands (n = 1), the US (n = 1), Taiwan (n = 1), Germany (n = 3), China (n = 5), and Italy (n = 6). Among these studies, six investigated and characterized the presence of MPs and NPs in the human urinary tract. MPs and NPs were detected in urine samples (n = 5), kidney cancer samples (n = 2), and bladder cancer samples (n = 1).

Additionally, 12 studies examined the effects of MPs and NPs on human urinary tract cell lines. Their findings suggest that MPs and NPs have cytotoxic effects, increase inflammation, reduce cell viability, and alter mitogen-activated protein kinase signaling pathways.

Raman spectroscopy was the primary method used to detect and characterize MPs and NPs in human samples (five out of six studies; 83%). Alternatively, pyrolysis-gas chromatography-mass spectrometry combined with direct laser infrared spectroscopy was used in one study.
 

Further Research Needed

This exploratory study underscores the urgent need for further research and policy development to address the challenges posed by microplastic contamination. It highlights the rapidly emerging threat of human urinary tract contamination by microplastics, questioning the WHO’s claim that microplastics pose no public health risk. The documented cytotoxic effects of microplastics, and their ability to induce inflammation, reduce cell viability, and disrupt signaling pathways, raise significant public health concerns related to bladder cancer, chronic kidney disease, chronic urinary infections, and incontinence.

Since plastics became widely used in the mid-20th century, they have evolved from a novel substance to an essential component in countless applications, with global production reaching 368 million tons in 2019 and expected to double by 2039. The production and degradation of plastics involve physical, chemical, and biological processes, leading to the formation of tiny fragments known as microplastics (MPs) and nanoplastics (NPs), which accumulate in the environment. Beyond the well-documented environmental harms of MPs and NPs, growing evidence of their presence within the human body raises concerns about their potential to trigger various harmful biological processes. Their detection in the urinary tract and their potential links to kidney and bladder diseases, as shown in animal studies, are particularly alarming.
 

Impacts Becoming Apparent

As the impact of plastic pollution becomes increasingly apparent, the need for standardized international definitions of MPs and NPs is pressing. Government publications reveal notable discrepancies between organizations in defining these fragmented plastics. The lack of consensus among regulatory bodies highlights the challenges in mitigating the environmental and health impacts of MPs and NPs. The International Organization for Standardization offers the most precise classification, defining MPs as solid, insoluble plastic particles ranging from 1 µm to 1 mm and NPs as particles smaller than 1 µm.

The intrusion of MPs and NPs into the human body, whether through inhalation, ingestion, or skin exposure (via wounds, hair follicles, or sweat glands), has been linked to harmful biological effects, including inflammation, alterations in cellular metabolism, physical cellular damage, and reduced cell viability.
 

Urinary Tract Plastics

The detection of MPs and NPs in the human urinary tract, combined with limited understanding of their effects, is a growing concern. An exploratory study published earlier this year aimed to systematically summarize the existing literature regarding the presence of MPs and NPs in the urinary tract and their potential consequences, guided by these research questions:

• What are the characteristics of the plastics detected in the human urinary tract?
• How are MPs and NPs defined in the current literature?
• What methodologies are used to explore the presence and effects of MPs and NPs?
• What are the pathophysiologic consequences of the presence of MPs and NPs in the human urinary tract?

For this study, the “urinary tract” included the kidneys, bladder, ureter, urethra, and urine. By focusing on the urinary tract, the study aimed to consolidate current understanding of MPs and NPs, raise awareness of this emerging issue, and lay the groundwork for further research that could contribute to public health policies and clinical practice guidelines.

The researchers conducted a scoping literature review following the recommendations of the JBI [formerly known as the Joanna Briggs Institute). They systematically searched five databases — PubMed, Scopus, CINAHL, Web of Science, and Embase — as well as gray literature sources.
 

Concerning Study Results

Eighteen articles were identified. The authors represent seven countries: Pakistan (n = 1), the Netherlands (n = 1), the US (n = 1), Taiwan (n = 1), Germany (n = 3), China (n = 5), and Italy (n = 6). Among these studies, six investigated and characterized the presence of MPs and NPs in the human urinary tract. MPs and NPs were detected in urine samples (n = 5), kidney cancer samples (n = 2), and bladder cancer samples (n = 1).

Additionally, 12 studies examined the effects of MPs and NPs on human urinary tract cell lines. Their findings suggest that MPs and NPs have cytotoxic effects, increase inflammation, reduce cell viability, and alter mitogen-activated protein kinase signaling pathways.

Raman spectroscopy was the primary method used to detect and characterize MPs and NPs in human samples (five out of six studies; 83%). Alternatively, pyrolysis-gas chromatography-mass spectrometry combined with direct laser infrared spectroscopy was used in one study.
 

Further Research Needed

This exploratory study underscores the urgent need for further research and policy development to address the challenges posed by microplastic contamination. It highlights the rapidly emerging threat of human urinary tract contamination by microplastics, questioning the WHO’s claim that microplastics pose no public health risk. The documented cytotoxic effects of microplastics, and their ability to induce inflammation, reduce cell viability, and disrupt signaling pathways, raise significant public health concerns related to bladder cancer, chronic kidney disease, chronic urinary infections, and incontinence.

TOPLINE:

About one in six women experience symptoms of postpartum depression (PPD) 2 months after cesarean delivery, with certain obstetric factors such as emergency cesarean delivery before labor, cesarean delivery after labor induction, lack of social support in the operating room, and severe postoperative pain influencing the risk.

METHODOLOGY:

• Researchers conducted a prospective ancillary cohort study of the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial to examine the prevalence of PPD 2 months after cesarean delivery and associated risk factors.
• A total of 2793 women (median age, 33.5 years) were included who had a cesarean delivery at 34 or more weeks of gestation; they completed the Edinburgh Postnatal Depression Scale (EPDS), a self-administered questionnaire, at 2 months after delivery.
• Information about the cesarean delivery, postpartum blood loss, immediate postpartum period, psychiatric history, and memories of delivery and postoperative pain were prospectively collected.
• Medical records were used to obtain details about characteristics of patients; 5.0% had a psychiatric history (2.4% composed of depression).
• The main endpoint was a positive screening for symptoms consistent with this depression — defined as a PPD diagnosis — 2 months after caesarian delivery, with an EPDS score of 13 or higher.

TAKEAWAY:

• The prevalence of a provisional PPD diagnosis at 2 months after cesarean delivery was 16.4% (95% CI, 14.9-18.0) with an EPDS score of 13 or higher and was 23.1% (95% CI, 21.4-24.9%) with a cutoff value of 11 or higher.
• Women who had an emergency cesarean delivery before labor had a higher risk for PPD than those who had a normal cesarean delivery before labor started (adjusted odds ratio [aOR], 1.70; 95% CI, 1.15-2.50); women who had started labor after induction but then had a cesarean delivery also had a higher risk for PPD than those who had a cesarean delivery before going into labor (aOR, 1.36; 95% CI, 1.03-1.84).
• Severe pain during the postpartum stay (aOR, 1.73; 95% CI, 1.32-2.26) and bad memories of delivery (aOR, 1.67; 95% CI, 1.14-2.45) were also risk factors for PPD.
• However, women who had social support in the operating room showed a 27% lower risk for PPD (P = .02).

IN PRACTICE:

“Identifying subgroups of women at risk for PPD based on aspects of their obstetric experience could help to screen for women who might benefit from early screening and interventions,” the authors wrote.

SOURCE:

This study was led by Alizée Froeliger, MD, MPH, of the Department of Obstetrics and Gynecology at Bordeaux University Hospital in France, and was published online in American Journal of Obstetrics & Gynecology.

LIMITATIONS:

The study population was derived from a randomized controlled trial, which may have underestimated the prevalence of PPD. The use of a self-administered questionnaire for PPD screening may not have provided a definitive diagnosis. Moreover, this study did not assess the prevalence of depressive symptoms during pregnancy.

DISCLOSURES:

The TRAAP2 trial was supported by a grant from the French Ministry of Health under its Clinical Research Hospital Program. One author reported carrying out consultancy work and lecturing for Ferring Laboratories, GlaxoSmithKline, and other pharmaceutical companies.
