RESUMO
Obesity is the most common medical problem in women of reproductive age. The surgical applications for this population, many of who are interested in current or future fertility, are critical to safe and effective evaluation and management of issues that impact the reproductive system. As rates of obesity continue to rise worldwide, it is projected that one in two individuals will have obesity by 2030 leading to increasing numbers of individuals affected by a disease process that has implications for their gynecologic surgical care, fertility-related assessment, and infertility treatment. Offering patients with obesity access to safe reproductive surgery is a cornerstone of reproductive autonomy. This review will summarize current recommendations regarding surgical concepts for the operating room, office hysteroscopy, oocyte retrieval, and embryo transfer in female patients with obesity.

PURPOSE: Contact tracing elicits probable contacts from COVID-19 cases. Our student-led contact tracing initiative promoted isolation of both confirmed and probable cases and quarantine of contacts to reduce disease in Central Pennsylvania. METHODS: Close contacts of COVID-19 cases were contacted by tracers, advised to quarantine, and monitored for 14 days for symptoms. Symptomatic contacts were classified as probable cases and advised to isolate. Data was collected from March 24, 2020 to May 26, 2020. Poisson regression and linear regression were utilized to examine the relationships between case and number of contacts and proportion of symptomatic contacts. RESULTS: Study sample comprised of 346 confirmed and 157 probable cases. Our results indicate a significant difference in percent of household contacts who became symptomatic between confirmed and probable cases (22% vs. 3%; adjusted P<.01). Similarly, probable cases had significantly fewer non-household contacts compared to confirmed cases (0.87 vs. 0.55; adjusted P<.01). CONCLUSIONS: Timely notification of exposure to a COVID-19 positive individual by student contact tracers allowed for probable cases to quarantine early in the disease process. Our data suggests that early quarantine and/or isolation may have directly contributed to probable cases having fewer non-household contacts and a smaller proportion of symptomatic household-contacts compared to confirmed cases.

Purpose Marijuana use has been increasing in the adolescent population. Our objective was to examine the prevalence of marijuana use among a sample of adolescents and young adults, determine an association with risk-taking behaviors, identify reported medical symptoms, and delineate common beliefs about marijuana use. Methods A questionnaire was administered to a sample of patients aged between 12 and 23 years old presenting to the emergency department of Penn State Hershey Medical Center, Hershey, Pennsylvania. Data were stratified by marijuana users and non-users, and further stratified by traditional (vape, pipe, edibles) and non-traditional (oils/concentrates, topical creams) use. Results The analysis was based on 200 questionnaires. Thirty-nine percent (n=78) reported marijuana use. Marijuana users were more likely to report previous sexual intercourse (79.5% vs. 32.8%; p=<0.0001), as well as the use of alcohol (50.0% vs. 10.7%; p=<0.0001), cigarettes (41% vs. 8.2%; p=<0.0001), prescription pain medications (20.5% vs. 4.1%; p=0.002), and cocaine (14.1% vs. 0.8%; p=0.0017). Users more likely reported texting while driving (41.0% vs. 13.1%; p=0.005) and experienced physical or electronic victimization due to bullying (43.6% vs. 19.7%; p=0.002). Users were more likely to report gastroesophageal reflux disease (GERD), attention deficit disorder (ADD), anxiety, and depression. The most common symptoms associated with marijuana use were anxiety (65.4%), headache (61.6%), nausea/vomiting (53.8%), cough (51.3%), and abdominal pain (47.4%). Sixty-nine percent of respondents believed marijuana was "safer than other drugs". Conclusion Based on our sample, we identified risk-taking behaviors, medical symptoms, and beliefs associated with marijuana use. Healthcare professionals may use these data to provide screening and anticipatory guidance to adolescents who use marijuana and consider marijuana use in their differential diagnosis.
RESUMO
Resurgence is defined as an increase in the frequency of a previously reinforced target response when an alternative source of reinforcement is suspended. Despite an extensive body of research examining factors that affect resurgence, the effects of alternative-reinforcer magnitude have not been examined. Thus, the present experiments aimed to fill this gap in the literature. In Experiment 1, rats pressed levers for single-pellet reinforcers during Phase 1. In Phase 2, target-lever pressing was extinguished, and alternative-lever pressing produced either five-pellet, one-pellet, or no alternative reinforcement. In Phase 3, alternative reinforcement was suspended to test for resurgence. Five-pellet alternative reinforcement produced faster elimination and greater resurgence of target-lever pressing than one-pellet alternative reinforcement. In Experiment 2, effects of decreasing alternative-reinforcer magnitude on resurgence were examined. Rats pressed levers and pulled chains for six-pellet reinforcers during Phases 1 and 2, respectively. In Phase 3, alternative reinforcement was decreased to three pellets for one group, one pellet for a second group, and suspended altogether for a third group. Shifting from six-pellet to one-pellet alternative reinforcement produced as much resurgence as suspending alternative reinforcement altogether, while shifting from six pellets to three pellets did not produce resurgence. These results suggest that alternative-reinforcer magnitude has effects on elimination and resurgence of target behavior that are similar to those of alternative-reinforcer rate. Thus, both suppression of target behavior during alternative reinforcement and resurgence when conditions of alternative reinforcement are altered may be related to variables that affect the value of the alternative-reinforcement source.
