Objectives: The purpose of this non interventional study was to define changes in anxiety, depression, and sleep quality of medical students in their first two years of medical school while considering potential risk factors of self-reported chronic disease, sleep quantity, year of medical school and exercise habits. Since this study was ongoing during the COVID-19 pandemic, its effect was also evaluated. Participants: /METHODS: A cohort of 197 medical students was evaluated longitudinally using survey methods to quantify changes from pre-medical school and summer break to each semester in medical school throughout years one and two. This study was performed from July 2019 through June 2021. Data was analyzed using Generalized Linear Mixed Models (GLMMs) on the numeric responses of General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Sleep Quality (SQ-3) and Pittsburg Sleep Quality Index (PSQI). Additional assessments evaluated exercise habits, chronic disease, and impact of COVID-19 Pandemic. The COVID-19 Pandemic was evaluated directly in the model (pre- and post-COVID-19 period variable), and through additional questions on their perceived effect. Results: Depression, anxiety, and sleep habits displayed a cyclical change that was associated with the academic/seasonal cycle. The COVID-19 pandemic was never found significant. Medical students who had a chronic disease diagnosis and fewer hours of sleep had increased severity. Exercise did not play a role. Conclusion: Based on our sample, the main driver for depression, anxiety, and poor sleep quality appears to be the academic/seasonal cycle, while the COVID-19 pandemic did not have an impact on mental health.

Context: Updated data on the use of Osteopathic Manipulative Treatments (OMT) by osteopathic physicians in the United States is overdue. This data would provide an up-todate point of reference for evaluating the current use of OMT as a distinguishing feature of the osteopathic profession. Objective: To determine the prevalence of OMT use, barriers to its use, and factors that correlate with increased use. Methods: The American Osteopathic Association (AOA) distributed its triannual survey on professional practices and preferences of osteopathic physicians, including questions on OMT, to a random sample of 10,000 osteopathic physicians in August 2018 through Survey Monkey (San Mateo, CA). Follow-up efforts included a paper survey mailed to nonrespondents one month after initial distribution and three subsequent email reminders. The survey was available from August 15, 2018 to November 5, 2018. The OMT questions focused on frequency of OMT use, perceived barriers, and basic demographic information of osteopathic physician respondents. Statistical analysis (including a one sample test of proportion, chi-square, and Spearman's rho) was performed to identify significant factors influencing OMT use. Results: Of 10,000 surveyed osteopathic physicians, 1,683 (16.83%) responded. Of those respondents, 1,308 (77.74%) reported using OMT on less than 5% of their patients, while 958 (56.95%) did not use OMT on any of their patients. Impactful barriers to OMT use included lack of time, lack of reimbursement, lack of institutional/practice support, and lack of confidence/proficiency. Factors positively correlated with OMT use included female gender, being full owner of a practice, and practicing in an office-based setting. Conclusion: Our data suggest that OMT use among osteopathic physicians in the US continues to decline. Barriers to its use appear to be related to the difficulty that most physicians have with successfully integrating OMT into the country's insurance-based system of healthcare delivery. Follow-up investigations on this subject in subsequent years will be imperative in the ongoing effort to monitor and preserve the distinctiveness of the osteopathic profession.

Vaccination is one of the most effective preventative health measures in modern times. It has positively affected the incidence and prevalence of a myriad of diseases, as well as improved both their morbidity and mortality. It is essential that health care providers understand the value of this intervention, promote comprehensive immunization coverage within their community, and recognize the underlying principles that guide decisions regarding vaccination. Factors important to consider before immunization administration include the type of vaccination, its recommended timing and intervals, and the presence of contraindications, precautions, or other special considerations.
