Objective: To determine whether medical students significantly impact preceptor physicians"™ clinic volume and work after clinic (WAC), we compared the time to note completion and the number of patients seen per hour (PPH) for outpatient neurologists with and without students present in their clinic. Methods: Outpatient neurologists (n = 47) involved in the Johns Hopkins Neurology Clerkship from 2015 to 2017 were included. WAC for each patient encounter was calculated as the interval between the date and time of a scheduled patient appointment and the time of clinic note completion. The number of patient encounters per scheduled clinic hour (PPH) was also calculated for each preceptor. Measurements were compared for each preceptor, serving as their own control, to account for variability in efficiency between preceptors. Results: There was no statistically significant difference in WAC or PPH for individual preceptors with and without students (WAC p-value = 0.837; PPH p-value = 0.139). Preceptors did see significantly more patients per day with students than without (6.28 with students, 5.07 without students, p-value <0.001). Conclusions: In this study, assigning a student to an outpatient ambulatory clinic did not significantly increase work after clinic. In addition, students did not significantly alter the number of patients faculty saw per hour. Public Interest Summary: Both medical students and educators have highlighted the importance of greater student involvement in clinic in providing a valuable outpatient educational experience, but it is often difficult for academic programs to recruit physician preceptors willing to teach and actively involve students in outpatient clinics. This study shows that medical student presence in clinic does not delay physician preceptors"™ note completion and is not associated with less patients seen. To further optimize the outpatient educational and efficiency model, it is important for future investigations to evaluate training programs that enhance the efficacy of a student in clinic, particularly for students with less outpatient experience. This could encourage more preceptors to involve medical students in their clinic, potentially increasing student competence and interest in outpatient medicine.

Unwanted sexual incidents on university campuses pose significant public health and safety risks for students. This study explored survivors' perspectives on secondary prevention of campus sexual assault and effective strategies for intervention programs for unwanted sexual incidents in university settings. Twenty-seven student survivors of unwanted sexual experiences participated in semi-structured in-depth interviews. Data were analyzed using thematic analysis and a constructionist perspective. The findings were contextualized using the ecological model. Barriers to reporting included concerns about one's story not being believed, personal minimization of the incident, belief that no action will be taken after reporting, confidentiality concerns, and other perceived costs of reporting. Survivors provided valuable insight on potentially effective prevention and intervention strategies to address the problem of unwanted sexual incidents on university campuses. These findings may be useful for prevention and intervention policies and programs in university settings and for providers who assist survivors of unwanted sexual experiences.

Chronic pain (CP) and opioid use disorder (OUD) remain challenging complex public health concerns. This is an updated review on the relationship between CP and OUD and the use of stepped care models for assessment and management of this vulnerable population. A literature search was conducted from 2008 to the present in PubMed, Embase, and PsycInfo using the terms pain or chronic pain and opioid-related disorders, opiate, methadone, buprenorphine, naltrexone, opioid abuse, opioid misuse, opioid dependen*, heroin addict, heroin abuse, heroin misuse, heroin dependen*, or analgesic opioids, and stepped care, integrated services, multidisciplinary treatment, or reinforcement-based treatment. Evidenced-based data exists on the feasibility, implementation, and efficacy of stepped care models in primary care settings for the management of CP and opioid use. Although these studies did not enroll participants with OUD, they included a sub-set of patients at risk for the development of OUD. There remains a dearth of treatment options for those with comorbid CP and OUD. Future research is needed to explore the aetiology and impact of CP and OUD, and greater emphasis is needed to improve access to comprehensive pain and substance use programmes for high-risk individuals.

BACKGROUND:African American adults achieve smaller amounts of weight loss than their white counterparts when exposed to the same intervention and are more likely to regain weight during long-term follow-up. OBJECTIVE:To identify perceived motivators, barriers, and facilitators to weight loss and behavior change among African American adults. METHODS:Two focus groups were conducted between April and May 2015 at an urban community health center in Baltimore City, Maryland. A total of 13 participants took part in the discussions. Eligible participants were obese (BMI 30+) African American adults aged 21-70 who had at least one obesity-related comorbidity. Discussion questions were designed to identify the personal, social, and environmental factors that influence weight loss and behavior change among urban minority populations. RESULTS:Statements were first classified as a motivator, barrier, or facilitator, then divided further as a personal, social, or environmental factor influencing weight loss and behavior change. Among the findings, several novel motivators (reducing or eliminating medication, improving physical intimacy) and barriers (personal transportation, lack of access to scales) emerged that were not previously characterized in the existing literature. CONCLUSIONS:This study was intended to provide preliminary evidence that may be used to guide the development of innovative and culturally relevant weight-loss interventions in the future. Results are applicable to similar urban minority populations.

Acinetobacter baumannii has quickly become one of the most insidious and prevalent nosocomial infections. Recently, the reverse-amide class of 2-aminoimidazole compounds (RA-2AI) was found both to prevent A. baumannii biofilm formation and also to disperse preexisting formations, putatively through interactions with cytosolic response regulators. Here we focus on how this class of antibiofilm agent traverses cellular membranes. Following the discovery of dosage-dependent growth rate changes, the cellular effects of RA-2AI were investigated using a combination of molecular assays and microscopic techniques. It was found that RA-2AI exposure has measureable effects on the bacterial membranes, resulting in a period of increased permeability and visible structural aberrations. Based on these results, we propose a model that describes how the structure of RA-2AI allows it to insert itself into and disrupt the fluidity of the membrane, creating an opportunity for increased molecular permeability.
