Women express low decision regret after preimplantation testing for aneuploidy
undergoing fertility treatment, research suggests.
In a report published in Human Reproduction, researchers did an anonymous survey of 69 patients undergoing their first cycle of autologous preimplantation genetic testing for aneuploidy (PGT-A) at a single fertility center.
“Despite the known distress associated with many aspects of assisted reproductive technology (ART) and the many opportunities for distress among patients pursuing PGT-A, little is known about the associated patient experience and psychological risks,” wrote Dr. Kara N. Goldman of New York University Langone Fertility Center, and coauthors.
“A ‘failure’ after PGT-A can present in many forms well before other IVF losses may be experienced: Embryos may not meet criteria for biopsy, PGT-A may result in an all-aneuploid embryo cohort, or a euploid embryo may fail to implant,” the authors continued.
The mean overall decision regret scale score was 8.5 on a scale of 0-100 – with a median of 0 – and 61% of respondents said they had no regrets about undergoing preimplantation genetic testing for aneuploidy; the remaining 39% reported “any degree of regret.”
This “one-third of respondents reported some degree of regret, suggesting an important opportunity for pretest counseling and support among patients pursuing PGT-A,” Dr. Goldman and associates emphasized.
Of the respondents who then underwent euploid embryo transfer, and who had a known pregnancy outcome, the 36 with an ongoing or delivered pregnancy had significantly less decision regret than the 24 who experienced a negative pregnancy test or a miscarriage.
The study found no differences in decision regret between those aged under or over 35 years of age, those with different levels of educational attainment, or between patients who paid exclusively out of pocket compared with those with any insurance coverage.
However, greater levels of decision regret were seen in patients who had experienced a longer time since retrieval of oocytes and those who said they would consider pregnancy with donor oocytes if they were unsuccessful with IVF and PGT-A.
“Completing a cycle of IVF with PGT-A and obtaining no usable, euploid embryos results in distress, but this distress must be weighed against the alternative scenario in which a patient invests valuable time, energy, and resources into a futile embryo transfer cycle resulting in a negative pregnancy test, miscarriage, or aneuploid gestation,” the authors wrote.
When assessing the dependence of the decision regret score on demographic factors, the researchers found that patients who had learned about PGT-A from their physicians, rather than from other sources such as friends or the Internet, had the highest levels of decision regret.
There was no external funding. One coauthor declared personal fees and other support from the fertility and pharmaceutical sector. No other conflicts of interest were declared.

Split-dose oxycodone protocol reduces opioid use after cesarean
A retrospective study reviewed medical records of 1,050 women undergoing cesarean delivery, 508 of whom were treated after a change in protocol for postdelivery oxycodone orders. Instead of a 5-mg oral dose given for a verbal pain score of 4/10 or below and 10 mg for a pain score of 5-10/10, patients were given 2.5-mg or 5-mg dose respectively, with a nurse check after 1 hour to see if more of the same dosage was needed.
The split-dose approach was associated with a 56% reduction in median opioid consumption in the first 48 hours after cesarean delivery; 10 mg before the change in practice to 4.4 mg after it. There was also a 6.9-percentage-point decrease in the number of patients needing any postoperative opioids.
While the study did show a slight increase in average verbal pain scores in the first 58 hours after surgery – from a mean of 1.8 before the split-dose protocol was introduced to 2 after it was introduced – there was no increase in the use of nonsteroidal anti-inflammatory drugs, acetaminophen, or gabapentin, and no difference in peak verbal pain scores.
“Our goal with the introduction of this new order set was to use a patient-centered, response-feedback approach to postcesarean delivery analgesia in the form of split doses of oxycodone rather than the traditional standard dose model,” wrote Jalal A. Nanji, MD, of the department of anesthesiology and pain medicine at the University of Alberta, Edmonton, and coauthors. “Involving patients in the decision for how much postcesarean delivery analgesia they will receive has been found to reduce opioid use and improve maternal satisfaction.”
The number of patients reporting postoperative nausea or vomiting was halved in those treated with the split-dose regimen, with no difference in mean overall patient satisfaction score.
Dr. Nanji and associates wrote that women viewed avoiding nausea or vomiting after a cesarean as a high priority, and targeting the root cause – excessive opioid use – was preferable to treating nausea and vomiting with antiemetics.
They also noted that input from nursing staff was vital in developing the new split-order set, not only because it directly affected nursing work flow but also to optimize the process.
“With the opioid epidemic on the rise and the increase in efforts by physicians to decrease outpatient opioid prescriptions, this study is extremely relevant and timely,” commented Marissa Platner, MD, an assistant professor in maternal-fetal medicine at Emory University, Atlanta.
“Although this study is retrospective and, therefore, there are inherent biases and an inability to control all contributing factors, it clearly demonstrates that, overall, there seem to be improved outcomes with split-dose protocol of opioid administration during the postoperative period in terms of overall patient satisfaction, opioid consumption, and postoperative nausea and vomiting. The patient-centered nature and response-feedback design of this study also contributes to its strength and improves its generalizability. In order to encourage others to considering adapting protocol in other institutions, it should be evaluated via a randomized controlled trial," Dr. Platner said in an interview.*
"The premise and execution of this study were novel and interesting," commented Katrina Mark, MD, associate professor of obstetrics, gynecology & reproductive sciences at the University of Maryland School of Medicine. "The authors found that by decreasing the standard doses of oxycodone ordered after a cesarean section and asking women if they desired better pain control, rather than reacting only to a pain score, patients’ overall postoperative usage of opiates also decreased. In decreasing the amount of opiates used, the authors also observed a decrease some of the side effects associated with opiate use, which is promising.
"This study, among other recent studies, highlights the fact that postoperative prescribing standards are not evidence-based and may lead to overprescribing of opiates. Improving prescribing practices is a noble and important goal. In this study, a change in clinical practice among both nurses and prescribers is likely what caused the greatest change. The use of a protocol which prescribed oxycodone based on asking if a woman desired improved pain control, rather than prescribing only based on her pain score response, makes a lot of intuitive sense. Decreasing opioid consumption requires education of healthcare providers and patients, and protocols like this one will help to encourage that conversation," she noted in an interview.
"Before the findings of this study can be widely adopted, however, there are two major points that will need to be addressed," Dr. Mark emphasized. "The first is patient satisfaction. The peak pain scores were not different between the groups, but the mean pain scores were. The authors deemed this clinically insignificant, which it may be. However, without the patients’ perspective on this new protocol, it is difficult to tell if the opioid usage decreased because women actually needed less opiates or if it decreased because the system discouraged opioid use and made it more challenging for them to obtain the medicine they needed to achieve adequate pain control. The desire to decrease opioid prescribing is warranted, and likely completely appropriate, but there is certainly a role for opioids in pain management. We should not be so motivated to decrease use that we cause unnecessary suffering. The second point that will need to be addressed is the effect on nursing practice. There was no standardized evaluation of the impact that this protocol had on the nursing staff, and it is unclear if this protocol would require greater resources than may be readily available at all hospitals."**
The study was supported by the department of anesthesiology, perioperative, and pain medicine at Stanford (Calif.) University. One author declared travel funding from a university. No other conflicts of interest were declared. Dr. Platner and Dr. Mark also had no relevant financial disclosures.*

Risk of cardiac events jumps after COPD exacerbation
particularly in older individuals, new research has found.
In Respirology, researchers report the outcomes of a nationwide, register-based study involving 118,807 patients with chronic obstructive pulmonary disease (COPD) who experienced a major adverse cardiac event after an exacerbation.
They found that the risk of any major cardiac adverse event increased 270% in the 4 weeks after the onset of an exacerbation (95% confidence interval, 3.60-3.80). The strongest association was seen for cardiovascular death, for which there was a 333% increase in risk, but there was also a 257% increase in the risk of acute MI and 178% increase in the risk of stroke.
The risk of major adverse cardiac events was even higher among individuals who were hospitalized because of their COPD exacerbation (odds ratio, 5.92), compared with a 150% increase in risk among those who weren’t hospitalized but were treated with oral corticosteroids and 108% increase among those treated with amoxicillin with enzyme inhibitors.
The risk of a major cardiac event after a COPD exacerbation also increased with age. Among individuals younger than 55 years, there was a 131% increase in risk, but among those aged 55-69 years there was a 234% increase, among those aged 70-79 years the risk increased 282%, and among those aged 80 years and older it increased 318%.
Mette Reilev, from the department of public health at the University of Southern Denmark, Odense, and coauthors suggested that acute exacerbations were associated with elevated levels of systemic inflammatory markers such as fibrinogen and interleukin-6, which were potently prothrombotic and could potentially trigger cardiovascular events.
“Additionally, exacerbations may trigger type II myocardial infarctions secondary to an imbalance in oxygen supply and demand,” they wrote.
The authors raised the question of whether cardiovascular prevention strategies should be part of treatment recommendations for people with COPD, and suggested that prevention of COPD exacerbations could be justified even on cardiovascular grounds alone.
“Studies investigating the effect of cardiovascular treatment on the course of disease among COPD exacerbators are extremely scarce,” they wrote. “Thus, it is currently unknown how to optimize treatment and mitigate the increased risk of [major adverse cardiovascular events] following the onset of exacerbations.”
However, they noted that prednisolone treatment for more severe exacerbations may have a confounding effect, as oral corticosteroids could induce dyslipidemia, hypertension, and hyperglycemia, and increase long-term cardiovascular risk.
Six authors declared funding from the pharmaceutical industry – three of which were institutional support – unrelated to the study.

Increased cancer death linked to radioactive iodine therapy
Radioactive iodine therapy for hyperthyroidism may be associated with an increased risk of death from cancer, according to a longitudinal cohort study published in the July 1 issue of JAMA Internal Medicine.
The study followed 18,805 individuals whose hyperthyroidism was treated with radioactive iodine in the United States and United Kingdom between 1946 and 1964.
Researchers found positive dose-response relationships between radioactive iodine therapy and most of the solid cancers that were evaluated. However these only attained statistical significance in the case of female breast cancer – where there was a 12% increase in the risk of death from breast cancer from a 100-mGy tissue- or organ-absorbed dose – or for all solid cancers combined, where a 100-mGy dose to the stomach was associated with a 6% increase in death from all solid cancers.
Based on this, the authors estimated that 8% of solid cancer deaths, including 14% of breast cancer deaths, could be attributed to the radiation. When combined with current US mortality rates, that translated to around 13 excess solid cancer deaths, including three deaths from breast cancer, for every 1000 patients receiving a 100 mGy absorbed dose to the stomach or breast at age 40 years.
However they noted that patients with Graves disease are now recommended to receive higher doses, and calculated that for 150-mGy, 200-mGy and 250-mGy dosages there would be 19-32 excess solid cancer deaths per 1000 patients treated at age 40 years.
“To our knowledge, this is the first study to characterize the dose-response relationship between RAI treatment and site-specific cancer mortality in patients with hyperthyroidism using reliable estimates of absorbed dose to exposed organs or tissues,” wrote Cari M. Kitahara, PhD, from the Division of Cancer Epidemiology and Genetics at the National Cancer Institute, and co-authors.
Radioactive iodine therapy did not appear to be associated with an increased risk of death from leukemia, non-Hodgkin lymphoma or multiple myeloma.
The authors noted that this was unexpected given previous findings of an elevated risk of leukemia in patients with thyroid cancer who received higher levels of radiation. They suggested that the greater uncertainty in calculation of red bone marrow exposure compared to that of other organs and tissue, as well as the relatively small number of leukemia deaths, may have limited their ability to detect a dose-response relationship.
The study was funded by the National Cancer Institute. One author declared membership of a consortium supported by the pharmaceutical sector.

Social media use linked to acceptance of cosmetic surgery
Use of social media platforms such as Tinder, Snapchat, and Instagram, particularly in conjunction with photo-editing applications, may increase an individual’s acceptance of cosmetic surgery, a new study suggests.
In JAMA Facial Plastic Surgery, researchers report the outcomes of a web-based survey study involving 252 participants, 73.0% of whom were female. The survey asked participants about their use of social media, photo-editing tools such as Photoshop, VSCO, and Snapchat filters, and answered questionnaires to assess their self-esteem, self-worth, and attitudes toward cosmetic surgery.
All participants used at least one social media platform, with a mean of seven, and used a mean of two photo-editing applications; the analysis found that those who used more social media platforms were more likely to consider cosmetic surgery.
People who used Tinder and Snapchat – with or without photo filters – showed greater acceptance of cosmetic surgery, while those who used the photography mobile app VSCO and Instagram photo filters showed greater consideration but not acceptance of cosmetic surgery, compared with nonusers.
Participants whose self-worth was more closely tied to their appearance showed greater acceptance of cosmetic surgery. When it came to self-esteem, participants who used YouTube, WhatsApp, VSCO, and Photoshop had lower self-esteem scores, compared with nonusers.
Overall, nearly two-thirds of survey participants said they used photo-editing applications to change the lighting of images, but only 5.16% said they used these applications to make changes to face or body shape. This distinction was also seen in their acceptance of cosmetic surgery scores: Those who said they made changes to face and body shape showed higher acceptance scores than nonusers, but this was not seen in those who only used it for lighting adjustments.
“The rising trend of pursuing cosmetic surgery based on social media inspiration highlights the need to better understand patients’ motivations to seek cosmetic surgery,” wrote Jonlin Chen, a medical student at Johns Hopkins University, Baltimore, and coauthors.
Commenting on the association between YouTube use, lower self-esteem, and higher acceptance of cosmetic surgery, the authors suggested that the platform may generate appearance comparisons between users by allowing them to access beauty-related videos and connect with other users interested in cosmetics.
Michael J. Reilly, MD, department of otolaryngology–head and neck surgery and Keon M. Parsa, MD, from the department of psychiatry at MedStar Georgetown University Hospital in Washington, commented in an accompanying editorial that the findings of this study illustrate an increased trend seen by facial plastic surgeons (JAMA Facial Plast Surg. 2019 June 27. doi: 10.1001/jamafacial.2019.0419). The study “shows the importance of understanding the underlying motives and characteristics of individuals seeking cosmetic surgery.” They noted that facial plastic surgeons can play a role in helping patients to improve their self-esteem, but it is also important to be aware of the clinical signs of depression, anxiety, and social isolation and refer for appropriate nonsurgical support when there are mental health concerns that go beyond the knife and needle.
The authors of the study did note that their choice of a web-based survey meant the demographic was likely to be skewed toward a younger, more social media–savvy demographic, and may not necessarily represent the broader population of individuals seeking cosmetic surgery.
No funding or conflicts of interest were declared.

Substantial reductions in HPV infections, CIN2+ after vaccination
The introduction of the human papillomavirus
according to a meta-analysis of data from more than 60 million individuals worldwide.Mélanie Drolet, PhD, from the Centre de recherche du CHU de Québec–Université Laval, and coauthors of the HPV Vaccination Impact Study Group reported the results of a systematic review and meta-analysis of 65 studies showing pre- and postvaccination frequency of at least one HPV-related endpoint published in the Lancet. The studies were conducted in 14 high-income countries, 12 of which were vaccinating only women and girls, with the results at 5-8 years published in the Lancet.
At 5-8 years after a vaccination program was implemented, there was a significant 83% reduction in the prevalence of HPV 16 and 18, both of which are targeted by the vaccine, among girls aged 13-19 years; a 66% reduction among women aged 20-24 years; and a 37% reduction in women aged 25-29 years, even though most of these women were unvaccinated.
There also were significant decreases at 5-8 years in the prevalence of HPV subtypes 31, 33, and 45, which are not included in the vaccine but against which the vaccine appears to offer cross-protection. Among girls aged 13-19 years, there was a significant 54% reduction in the prevalence of these subtypes, among women aged 20-24 years there was a nonsignificant 28% decrease, but among women aged 25-29 years, there was no significant decrease.
The analysis also found significant declines in the prevalence of cervical intraepithelial neoplasias (CINs) of grade 2 or above. At 5-9 years after vaccination was introduced, CIN2+ decreased by 51% among girls aged 15-19 years who also were screened for cervical cancer, and by 31% among women aged 20-24 years.
However, over the same time period, the rates of CIN2+ increased by a significant 19% among mostly unvaccinated women aged 25-29 years and 23% among mostly unvaccinated women aged 30-39 years, despite both groups being screened for cervical abnormalities.
While most of the countries in the study vaccinated only girls and women, two studies did find nonsignificant decreases in the prevalence of HPV 16, 18, 31, 33, and 45 among boys aged 16-19 years, but not among men aged 20-24 years.
HPV vaccination also was associated with significant declines in the incidence of anogenital warts among both males and females. In the first 4 years alone, vaccination was associated with significant reductions in anogenital wart diagnoses among females aged 15-29 years, as well as nonsignificant but “substantial” reductions in unvaccinated boys aged 15-19 years.
After 5-8 years, anogenital wart diagnoses decreased by 67% among girls aged 15-19 years, significantly by 54% among women aged 20-24 years, and 31% among women aged 25-29 years – all significant changes. Among boys aged 15-19 years, anogenital wart diagnoses decreased by a significant 48%, and among men aged 20-24 years they decreased by a significant 32%.
The decreases in anogenital wart diagnoses were even greater in countries that implemented vaccination among multiple cohorts simultaneously and achieved high vaccination coverage, compared with countries that vaccinated only one cohort at a time or had low routine vaccination coverage.
“Our study is the first to show the real-world additional benefit of multicohort HPV vaccination and high routine vaccination coverage, and the fast and substantial herd effects of vaccination in countries which implement these measures,” wrote Dr. Drolet and coauthors. “The greater impact of multicohort vaccination was similar when restricting the analyses to countries with high routine vaccination coverage.”
They pointed to the World Health Organization’s recently revised position on HPV vaccination, which now recommends vaccination of multiple cohorts of girls aged 9-14 years, although they raised the question of what might be the optimal number of age cohorts. “Number needed to vaccinate and cost-effectiveness analyses in high-income countries suggest that vaccinating multiple cohorts of individuals up to 18 years of age is highly efficient and cost effective.”
This analysis by Drolet et al. “provides compelling evidence for HPV vaccine efficacy on all outcomes explored and for almost all age strata,” Dr. Silvia de Sanjose, of PATH in Seattle, and Dr. Sinead Delany-Moretlwe of the Wits Reproductive Health and HIV Institute at the University of Witwatersrand in Johannesburg, said in an accompanying editorial (Lancet. 2019 Jun 26. doi: 10.1016/ S0140-6736[19]30549-5). This study shows just how effective HPV vaccination can be across a range of outcomes and ages, and also demonstrates the herd immunity benefits, particularly when multiple cohorts are vaccinated and there is high vaccination coverage.
One key limitation of this analysis is the lack of data from low- and middle-income countries. The data by Drolet et al. “emphasise the importance of redoubling our efforts to tackle the fiscal, supply, and programmatic barriers that currently limit HPV vaccine programmes; with these efforts, HPV vaccination could become a hallmark investment of cancer prevention in the 21st century,” Dr. de Sanjose and Dr. Delany-Moretlwe concluded.
The study was funded by WHO, Canadian Institutes of Health Research, and Fonds de recherche du Québec–Santé. No conflicts of interest were declared.
Dr. de Sanjose declared previous institutional support from Merck.

Key clinical point: Significant declines in HPV infections, CIN2+, and anogenital warts have occurred after the introduction of HPV vaccine programs, some because of herd effects.

Barrett’s esophagus endoscopies are undersampled
As many as one in five endoscopies in patients with Barrett’s esophagus are not being done according to accepted protocol, say the authors of a study published online in Gastrointestinal Endoscopy.
The Seattle biopsy protocol, which is recommended in nondysplastic Barrett’s esophagus to pick up esophageal adenocarcinoma, calls for four-quadrant biopsies at 2-cm intervals in patients without dysplasia and 1-cm intervals in patients with prior dysplasia, as well as targeted biopsies of any mucosal abnormalities.
Sachin Wani, MD, from the University of Colorado at Denver, Aurora, and coauthors used registry data to examine procedures and outcomes in 58,709 esophagogastroduodenoscopies in 53,541 patients with an endoscopic finding of, or screening indication for, Barrett’s esophagus.
They assessed protocol adherence by dividing the Barrett’s esophagus length by the number of pathology jars. A ratio of two or less was considered adherent, and the authors also allowed for a lenient rounding down, or stringent rounding up.
Just over half the procedures in the study (51.1%) resulted in a recorded, pathology-confirmed diagnosis of Barrett’s esophagus, and the mean length of Barrett’s esophagus was 2.3 cm.
Overall, 87.8% of endoscopies were adherent according to the lenient criteria, and 82.7% were adherent by the stringent definition.
Patients with longer lengths of Barrett’s esophagus were significantly less likely to be biopsied according to the Seattle biopsy protocol guidelines, with a 31% decrease in odds of adherence with every 1-cm increase in Barrett’s esophagus length. Patients with lengths from 0-4 cm were 76.3%-80.6% adherent to biopsy protocols, but those with lengths greater than 8 cm were only 37.9%-40.6% adherent.
“These results are most concerning because we found that dysplasia detection rates also increase with increasing [Barrett’s esophagus] length,” the authors wrote. “Therefore, per unit length, patients who need it most are being biopsied least.
Older and male patients also were less likely to be biopsied according to the protocol, and an American Society of Anesthesiologists classification of three or above was a predictor of nonadherence.
“These findings may be a reflection of a higher number of comorbidities in these patients with [Barrett’s esophagus] and perceived lack of benefit of surveillance endoscopy,” the authors wrote.
They also noted a geographic effect, such that patients living in the Northeast regions were more likely to be biopsied according to protocol than were those living in Western regions.
The study was funded by the University of Colorado department of medicine. Four authors declared consultancies and research grants from the medical device sector and others.

MRI-guided revascularization noninferior to FFR
Myocardial perfusion cardiovascular MRI is as good as invasive angiography and measurement of fractional flow reserve to guide revascularization in patients with angina, research suggests.
In the New England Journal of Medicine, researchers present the outcomes of an unblinded, multicenter, clinical effectiveness trial comparing the two revascularization strategies in 918 patients who had typical angina and either two or more cardiovascular risk factors or a positive exercise treadmill test.
In the fractional flow reserve method, revascularization was recommended in all vessels with an FFR of 0.8 or less. In the MRI-guided method, all patients underwent myocardial perfusion cardiovascular MRI, and patients with clinically significant inducible ischemia then underwent invasive angiography, and revascularization if required.
Significantly fewer patients in the cardiovascular MRI group underwent index revascularization, compared with the fractional flow reserve group (36% vs. 45% respectively; P = .005), and only 48% in the cardiovascular MRI group underwent invasive angiography, compared with 97% of patients in the fractional flow reserve arm.
However, there was no significant difference between the two groups in the incidence of major cardiac adverse events after 1 year, signifying that the MRI approach met the criteria for noninferiority.
There was also no significant difference between the two groups in the percentage of patients who were free from angina after 12 months (49.2% in the MRI group and 43.8% in the FFR group).
“Current guidelines on the management of the care of patients with suspected coronary artery disease separate diagnostic strategies from therapeutic strategies owing to a lack of evidence comparing combined diagnostic and therapeutic pathways,” wrote Eike Nagel, MD, of the Goethe University Frankfurt Institute for Experimental and Translational Cardiovascular Imaging and coauthors. “The MR-INFORM trial closes this knowledge gap by comparing two frequently used, well-defined, standardized, and validated clinical management strategies.”
However, they pointed out that one limitation of their study was the lack of a third group of patients who received medical therapy without planned revascularization. They also noted that the incidence of the primary outcome of major adverse cardiac events was lower than expected at 1 year.
The study was supported by the Guy’s and St. Thomas’ Biomedical Research Centre of the National Institute for Health Research. Three authors declared support from study supporters related to the study, three declared grants, personal fees, and other support from the private sector unrelated to the study. No other conflicts of interest were declared.

No cardiovascular benefit from vitamin D supplementation
There are no benefits from vitamin D supplementation in reducing the risk of major adverse cardiovascular events or all-cause mortality, according to a meta-analysis published in JAMA Cardiology.
Researchers analyzed data from 83,291 patients enrolled in 21 randomized, placebo-controlled clinical trials of at least 1 year of vitamin D supplementation.
They found the incidence of major adverse cardiovascular events was the same among patients taking vitamin D supplements and those taking placebo (risk ratio, 1; P = .85). Even stratifying by age, sex, postmenopausal status, pretreatment vitamin D levels, vitamin D dosage and formulation, chronic kidney disease, or excluding studies that used vitamin D analogues made no significant difference.
However, there was the suggestion of reduced incidence of major adverse cardiovascular events with vitamin D supplementation in individuals of advanced age, but the authors wrote that the finding should be interpreted with caution.
The analysis found no benefit from vitamin D supplementation on the secondary endpoints of MI, stroke, cardiovascular mortality, or all-cause mortality risk.
Mahmoud Barbarawi, MD, from the Hurley Medical Center at Michigan State University, East Lansing, and coauthors commented that previous observational studies have found significant associations between low vitamin D levels and cardiovascular events and all-cause mortality.
“However, observational studies are susceptible to uncontrolled confounding by outdoor physical activity, nutritional status, and prevalent chronic disease, which may influence serum 25-hydroxyvitamin D levels,” they wrote.
This updated analysis extended earlier clinical trial findings and added in some more-recent randomized trial outcomes, including the massive VITAL trial, which showed that neither daily vitamin D nor omega-3 fatty acids reduce cancer or cardiovascular event risk (N Engl J Med. 2019;380[1]:33-44).
Still, the authors noted that most of the trials included in the analysis had not prespecified cardiovascular disease as the primary endpoint and were underpowered to detect an effect on cardiovascular events. They also pointed out that few trials included data on heart failure, and a previous meta-analysis had suggested a potential benefit of supplementation in reducing the risk of this condition.
“Additional trials of higher-dose vitamin D supplementation, perhaps targeting members of older age groups and with attention to other [cardiovascular disease] endpoints such as heart failure, are of interest,” they wrote.
One author reported receiving funding from the National Institutes of Health and in-kind support from the pharmaceutical sector for a vitamin D study. No other disclosures were reported.

The past decade has seen a nearly 100-fold increase in vitamin D testing and supplementation, driven by a widespread fascination with the notion of vitamin D as a panacea. Vitamin D assessments alone are costing the United States an estimated $350 million annually.
Population and cohort studies have shown a clear link between vitamin D status and cardiovascular disease, but this link is complicated by the possibility that low serum 25-hydroxyvitamin D levels may be a result of, rather than the cause of, cardiovascular disease.
The findings of this meta-analysis, that vitamin D supplementation does not reduce the risk of major cardiovascular events and all-cause mortality, should support efforts to reduce unnecessary vitamin D testing and treatment in populations not at risk for deficiency or to prevent cardiovascular disease morbidity and mortality.

Metabolic and work productivity gains follow telemonitored exercise
while also improving productivity and mental health, research suggests.
In the June 13 online edition of Lancet Public Health, Dr. Sven Haufe of the Institute of Sports Medicine at Hannover Medical School in Germany and coauthors report the outcomes of a prospective, parallel-group, assessor-blind study of a telemonitoring-supported exercise intervention in 314 workers at a car factory. Of the participants, 162 did office work, 114 did manual work, and 30 did work that was not classified as falling under the office or manual work categories.
The participants, who had all been diagnosed with metabolic syndrome, were randomized to a 6-month exercise program involving personal counseling, use of a telemonitored activity monitor and regular feedback and consultation with an exercise scientist, or to continue their current lifestyle.
The participants were told to aim to complete 150 minutes of moderately intense physical activity per week for 6 months and to maintain a high level of daily activity. They were asked to maintain an individual heart rate range of 65%-75% relative to measured maximum heart rate when performing activities, such as walking, running, cycling, and using an elliptical trainer.
Participants wore their activity monitor, the Forerunner 35 (Garmin, Germany), on the wrist of their nondominant hand throughout the intervention period and were trained on how to use the device. Wearing time and steps were continuously recorded and recording of time, distance, and heart rate while performing cardiovascular exercise like riding a bicycle could be stopped and started by the participant. “Both continuous and self-started activity data were saved and directly forwarded via an interface from the Garmin server to a server at Hanover Medical school.” Participants also downloaded an application on their smartphones called Rebirth Active, which was specially designed for the study. The purposes of this app were to facilitate a close relationship between the participant and that participant’s supervising exercise scientist and to provide general information on the study, individual training goals, recommended heart rates during activities, tips for increasing physical activity, and the supervisor’s contact information.
Nearly half of the participants in the exercise program achieved at least the scheduled activity target of 150 minutes of physical activity per week, while the mean overall was 147 minutes per week. The researchers observed a significant reduction in mean metabolic syndrome z score in the intervention group – from 0.93 before the start of the study to 0.63 at the end of the program (P less than .0001). The control group’s mean z score level of improvement did not reach statistical significance (P = .167). The intervention was also associated with significant improvements in the metabolic syndrome components waist circumference, fasting glucose concentration, systolic blood pressure, and triglycerides, but not in HDL cholesterol levels. Additionally, the exercise group experienced greater reductions in mean body weight and mean percentage of body fat than the control group.
Workers who took part in the exercise program showed significant improvements in their performance on three subscales of the work ability index, including their current work ability, work ability in relation to demands, and mental resources. The control group showed no significant gains in these areas.
The intervention group also achieved gains in the physical and mental component scores of the quality of life questionnaires, which were significantly greater than those of the control group. Both the intervention and control groups had decreases in severity scores for anxiety and depression, but participants in the exercise program showed greater improvements.
“The observation that improvements in exercise capacity and mental health are associated with changes in work ability shows the need to offer similar interventions broadly across the working population,” the authors wrote, “not only to reduce individual risk of disease, but also to possibly ease the health care burden and economic costs arising from metabolic syndrome conditions in an aging population, an issue that should be addressed in further studies.”
The study was supported by Audi BKK health insurance and the German Research Foundation. No conflicts of interest were declared.

Workers who took part in the exercise program showed significant improvements in their performance on three subscales of the work ability index, including their current work ability, work ability in relation to demands, and mental resources. The control group showed no significant gains in these areas.
The intervention group also achieved gains in the physical and mental component scores of the quality of life questionnaires, which were significantly greater than those of the control group. Both the intervention and control groups had decreases in severity scores for anxiety and depression, but participants in the exercise program showed greater improvements.
“The observation that improvements in exercise capacity and mental health are associated with changes in work ability shows the need to offer similar interventions broadly across the working population,” the authors wrote, “not only to reduce individual risk of disease, but also to possibly ease the health care burden and economic costs arising from metabolic syndrome conditions in an aging population, an issue that should be addressed in further studies.”
The study was supported by Audi BKK health insurance and the German Research Foundation. No conflicts of interest were declared.

while also improving productivity and mental health, research suggests.
In the June 13 online edition of Lancet Public Health, Dr. Sven Haufe of the Institute of Sports Medicine at Hannover Medical School in Germany and coauthors report the outcomes of a prospective, parallel-group, assessor-blind study of a telemonitoring-supported exercise intervention in 314 workers at a car factory. Of the participants, 162 did office work, 114 did manual work, and 30 did work that was not classified as falling under the office or manual work categories.
The participants, who had all been diagnosed with metabolic syndrome, were randomized to a 6-month exercise program involving personal counseling, use of a telemonitored activity monitor and regular feedback and consultation with an exercise scientist, or to continue their current lifestyle.
The participants were told to aim to complete 150 minutes of moderately intense physical activity per week for 6 months and to maintain a high level of daily activity. They were asked to maintain an individual heart rate range of 65%-75% relative to measured maximum heart rate when performing activities, such as walking, running, cycling, and using an elliptical trainer.
Participants wore their activity monitor, the Forerunner 35 (Garmin, Germany), on the wrist of their nondominant hand throughout the intervention period and were trained on how to use the device. Wearing time and steps were continuously recorded and recording of time, distance, and heart rate while performing cardiovascular exercise like riding a bicycle could be stopped and started by the participant. “Both continuous and self-started activity data were saved and directly forwarded via an interface from the Garmin server to a server at Hanover Medical school.” Participants also downloaded an application on their smartphones called Rebirth Active, which was specially designed for the study. The purposes of this app were to facilitate a close relationship between the participant and that participant’s supervising exercise scientist and to provide general information on the study, individual training goals, recommended heart rates during activities, tips for increasing physical activity, and the supervisor’s contact information.
Nearly half of the participants in the exercise program achieved at least the scheduled activity target of 150 minutes of physical activity per week, while the mean overall was 147 minutes per week. The researchers observed a significant reduction in mean metabolic syndrome z score in the intervention group – from 0.93 before the start of the study to 0.63 at the end of the program (P less than .0001). The control group’s mean z score level of improvement did not reach statistical significance (P = .167). The intervention was also associated with significant improvements in the metabolic syndrome components waist circumference, fasting glucose concentration, systolic blood pressure, and triglycerides, but not in HDL cholesterol levels. Additionally, the exercise group experienced greater reductions in mean body weight and mean percentage of body fat than the control group.
Workers who took part in the exercise program showed significant improvements in their performance on three subscales of the work ability index, including their current work ability, work ability in relation to demands, and mental resources.
