Assessment of Nutritional Status and Health Perception among Male Inmates in Israeli Prisons.

The nutritional and health perceptions of inmates are crucial to their overall well-being. However, limited research has been conducted on this topic. This study aimed to assess the nutritional and health perception state of male inmates in eleven prisons in Israel. A cross-sectional study was conducted between February and September 2019 with 176 voluntary participants. Structured questionnaires were used to collect data on socio-demographic characteristics, healthy habits, subjective health status, and prison situation variables. The study found that the prevalence of overweight (40%) and obesity (18.1%) among 18-34-year-old inmates was significantly higher than in the reference Israeli population. Short detention periods (up to one year) predicted less weight gain, while older age predicted poorer health status. Better emotional status significantly predicted better subjective health status among male inmates. There is a need for nutrition interventions to improve the health of inmates. The significant weight gain during incarceration and the associated lower health index and stress highlights the importance of increasing knowledge and promoting a healthier lifestyle in incarceration as early as possible and continuing over time.

Racial and Gender Differences in Medical Student Burnout: A 2021 National Survey.

OBJECTIVE: To measure racial and gender differences in medical student burnout and identify possible contributing factors. PATIENTS AND METHODS: Electronic surveys were distributed to medical students at 9 US medical schools from December 27, 2020, through January 17, 2021. Questions covered demographic characteristics, stressors contributing to burnout, and the 2-item Maslach Burnout Inventory. RESULTS: Of 5500 invited students, 1178 (21%) responded (mean age, 25.3 years; 61% identified as female). Fifty-seven percent of respondents identified as White, 26% as Asian, and 5% as Black. Overall, 75.6% of students met the criteria for burnout. Women reported more burnout (78% vs 72%; P=.049). There were no differences in burnout prevalence by race. Students commonly reported that lack of sleep (42%), decreased engagement in hobbies or self-care (41%), stress about grades (37%), feeling socially disconnected (36%), and lack of exercise (35%) contributed to burnout. Compared with students of other races, Black students reported that their feelings of burnout were affected significantly more by lack of sleep and poor diet, and Asian students more by stress about grades, residency, and publishing pressure (all P<.05). Female students were more affected than male students by stress about grades, poor diet, and feelings of social disconnectedness and inadequacy (all P<.05). CONCLUSION: Burnout (75.6%) was higher than historical norms, and female students reported higher burnout than male students. There was no difference in burnout prevalence by race. There were racial and gender differences in self-identified contributors of burnout. Additional research is needed to confirm whether stressors were contributors to or consequences of burnout, as well as how to address them.

Recent Trends in Screening Breast MRI.

OBJECTIVE: The objective of this study was to assess trends in screening breast MRI utilization among privately insured women in the U.S. from 2007 to 2017. METHODS: The utilization of screening breast MRI among women aged 25-64 years from January 1, 2007, to December 31, 2017, was obtained using the MarketScan Commercial Database. We used Current Procedural Terminology codes to exclude breast MRI exams performed in women with a new breast cancer diagnosis and in women imaged to assess response to neoadjuvant therapy in the preceding 90 days. During the 11-year study, 351 763 study-eligible women underwent 488 852 MRI scans. RESULTS: An overall 55.0% increase in screening breast MRI utilization was observed over the study period, with a steadily increasing trend. The greatest annual increase in percent utilization was from 2007 to 2008 at 16.6%. The highest utilization rate was in 2017, in which 0.4% of women aged 25-64 years underwent screening breast MRI. Of the women who underwent screening MRI with sufficient follow-up, 76.5% underwent only one examination during the study period. CONCLUSION: Utilization of screening breast MRI has increased steadily in the past decade to a peak of 0.4% of adult women. However, an estimated 9% of U.S. women are eligible for high-risk breast MRI screening; thus, utilization falls short of optimal compliance. Further studies to evaluate the barriers to screening compliance may help optimize utilization.

Sleep in Populations of Drosophila Melanogaster

The fruit fly Drosophila melanogaster is a diurnal insect active during the day with consolidated sleep at night. Social interactions between pairs of flies have been shown to affect locomotor activity patterns, but effects on locomotion and sleep patterns have not been assessed for larger populations. Here, we use a commercially available locomotor activity monitor (LAM25H) system to record and analyze sleep behavior. Surprisingly, we find that same-sex populations of flies synchronize their sleep/wake activity, resulting in a population sleep pattern, which is similar but not identical to that of isolated individuals. Like individual flies, groups of flies show circadian and homeostatic regulation of sleep, as well as sexual dimorphism in sleep pattern and sensitivity to starvation and a known sleep-disrupting mutation (amnesiac). Populations of flies, however, exhibit distinct sleep characteristics from individuals. Differences in sleep appear to be due to olfaction-dependent social interactions and change with population size and sex ratio. These data support the idea that it is possible to investigate neural mechanisms underlying the effects of population behaviors on sleep by directly looking at a large number of animals in laboratory conditions.
