Metrics of HIV Pre-exposure Prophylaxis (PrEP) Implementation Before and After a Multidisciplinary Task Force at an Academic Institution.

BACKGROUND AND OBJECTIVES: There is a paucity of guidance on HIV pre-exposure prophylaxis (PrEP) implementation in an academic medical center. The objectives of this study were to describe interventions by a multidisciplinary PrEP task force at an academic medical center and compare metrics of PrEP implementation pre- and post-creation of this entity. METHODS: The interventions of the task force are described within the rubric of the PrEP care continuum. Participants were adults prescribed PrEP for greater than or equal to 30 days at 9 clinical sites across a university health system. Metrics of PrEP implementation were compared over 12-month intervals before and after the creation of the task force. RESULTS: An increased proportion of participants had HIV testing within 7 days of new PrEP prescriptions (92% vs 63%, P < .001) and were prescribed PrEP in increments of 90 days or shorter (74% vs 56%, P < .001) after the creation of the task force. There were higher rates of testing for bacterial sexually transmitted infections in men who had sex with men and transgender women in the post-intervention compared with pre-intervention period. CONCLUSIONS: A multidisciplinary team that focuses on optimizing PrEP delivery along each step of the care continuum may facilitate PrEP scale-up and best practices in an academic setting.

Injection Reactions after Administration of Sustained-release Meloxicam to BALB/cJ, C57BL/6J, and Crl:CD1(ICR) Mice.

The sustained-release formulation of meloxicam (MSR) is a compounded NSAID that may provide pain relief for as long as 72 h after administration. MSR injection-site skin reactions have occurred in several species but have not previously been observed in mice. We investigated the development and progression of localized skin reactions after a single injection of MSR in Crl:CD1(ICR), C57BL/6J, and BALB/cJ mice. Each mouse received a subcutaneous injection of MSR (n = 60), standard-formulation meloxicam (MEL; n = 24) or saline (control; SC; n = 24) and was scored daily according to a 5-point system for erythema and mass characteristics. Mice were euthanized at either 7 or 14 d after injection and underwent postmortem analysis. MSR-treated mice had more erythematous and mass reactions than did MEL and SC mice. Mass lesions developed in 49 MSR mice (82%; 95% CI, 70% to 90%), 5 MEL animals (21%; 95% CI, 7% to 42%), and 1 SC mouse. MSR-treated BALB/cJ developed erythematous lesions less frequently than similarly treated Crl:CD1(ICR) or C57BL/6J. Lesions often were ventrolateral to the injection site. The median times to the appearance of mass and erythematous lesions were 2 d and 3 d, respectively. Histologically, the erythematous and mass reactions correlated with necrotizing to pyogranulomatous injection-site panniculitis. Inflammation severity scores at 7 and 14 d after injection were greater in the MSR-treated group than the other 2 groups. No strain- or sex-associated differences emerged except that inflammation severity scores at day 14 were higher in Crl:CD1(ICR) females than males. The character of the inflammatory response in MSR-treated mice did not differ between 7 and 14 d after injection, indicating that MSR-induced inflammation is slow to resolve. The ventral migration and delayed onset of MSR injection-site reactions could result in their being attributed to another cause or not being identified. Researchers and clinicians should be aware of the potential for slowly resolving injection-site reactions with MSR.

Injection-site Reactions to Sustained-release Meloxicam in Sprague-Dawley Rats.

An extended-release formulation of the NSAID meloxicam (MSR) is used to provide 72 h of continuous analgesia in many species, including rodents. Although standard formulations of meloxicam are frequently used in rats with no observable injection-site reactions, the potential adverse effects from MSR have not been characterized sufficiently nor has a prospective study of these effects been performed in rats. To address this deficiency, we evaluated injection-site reactions after a single subcutaneous administration of MSR (n = 16) or sterile saline (SC, n = 6) in the flank of age- and sex-matched Sprague-Dawley rats. Mass and erythema scores were measured daily for 2 wk, and injection sites were collected for histopathology after euthanasia. Rats were randomly selected for euthanasia at 7 d (n = 12) or 14 d (n = 10) after injection to capture the subacute and chronic phases of mass and erythematic lesion formation. No rats in the SC group developed lesions, whereas all 16 MSR-treated rats developed masses. The median time to first mass in the MSR treatment group was 3 d (95% CI, 2-3 d), and nearly 8 d for erythema (95% CI, 6.7-9.1 d). The trajectory of mass lesion severity showed rapid progression from score 1 at onset (day 2 or 3) to score 2 for almost all animals by day 5 or 6. Histopathology was characterized by localized inflammation with central necrosis and peripheral fibrosis, with some sections showing developing draining tracts. Given the high prevalence and severity of localized skin reactions, MSR analgesia should be considered carefully for Sprague-Dawley rats.

Hypoglycemia after Bariatric Surgery in Mice and Optimal Dosage and Efficacy of Glucose Supplementation.

The Roux-en-Y Gastric Bypass (RYGB) mouse model is a vital tool for studying the pathophysiology of bariatric surgery and contributes greatly to research on obesity and diabetes. However, complications including postsurgical hypoglycemia can have profoundly negative effects. Unlike in humans, blood glucose (BG) is not typically managed in postoperative rodents, despite their critical role as translational models; without this management, rodents can experience hypoglycemia, potentially impairing wound healing, decreasing survivability, complicating interpretation of research data, and limiting translational utility. In this project, we sought to identify an optimal method for minimally invasive administration of dextrose in C57BL/6N (n = 16; 8 male, 8 female) mice. To do so, we characterized BG pharmacokinetic profiles after subcutaneous and oral-transmucosal (OTM) administration of dextrose. Compared with OTM dosage, the subcutaneous route provided more consistent and reliable delivery of glucose and did not cause significant adverse reactions. We then evaluated the frequency of hypoglycemic events after RYGB in C57BL/6N mice (n = 16; 8 male, 8 female) and the effects of subcutaneous dextrose supplementation on morbidity and mortality. BG measurement and behavioral pain assessment (grimace test) were performed for 3 d after surgery. Hypoglycemic (BG ≤ 60 mg/dL) animals were assigned to dose (5% dextrose SC) or no-dose treatment groups. Nearly all (87%) mice became hypoglycemic; 2 of these mice died. No significant intergroup difference in grimace score or mortality was detected. Overall, our results demonstrate that hypoglycemia is a frequent adverse event after RYGB in mice and that subcutaneous injection of dextrose is a safe and effective way to manage hypoglycemia. Further studies are necessary to optimize the intervention threshold and optimal dosage; regardless, we recommend glycemic management after RYGB surgery in mice.

Spinal epidural abscess caused by Gardnerella vaginalis and Prevotella amnii.

We report a case of spinal epidural abscess (SEA) in a 58-year-old woman who had recently been diagnosed with gonococcal infection, but did not receive guideline-recommended therapy. She presented with back pain and signs and symptoms of pelvic inflammatory disease (PID). MRI of the spine demonstrated epidural abscess extending from L4-L5 to T10. She underwent T10-L1 and L3-L4 laminectomies for evacuation of the abscess and Gardnerella vaginalis and Prevotella amnii were isolated from the abscess fluid cultures. Our case demonstrates SEA as a rare, but morbid complication of PID and highlights the pathogenic potential of the anaerobic flora associated with PID.

Barriers and facilitators to patient retention in HIV care.

BACKGROUND: Retention in HIV care improves survival and reduces the risk of HIV transmission to others. Multiple quantitative studies have described demographic and clinical characteristics associated with retention in HIV care. However, qualitative studies are needed to better understand barriers and facilitators. METHODS: Semi-structured interviews were conducted with 51 HIV-infected individuals, 25 who were retained in care and 26 not retained in care, from 3 urban clinics. Interview data were analyzed for themes using a modified grounded theory approach. Identified themes were compared between the two groups of interest: patients retained in care and those not retained in care. RESULTS: Overall, participants identified 12 barriers and 5 facilitators to retention in HIV care. On average, retained individuals provided 3 barriers, while persons not retained in care provided 5 barriers. Both groups commonly discussed depression/mental illness, feeling sick, and competing life activities as barriers. In addition, individuals not retained in care commonly reported expensive and unreliable transportation, stigma, and insufficient insurance as barriers. On average, participants in both groups referenced 2 facilitators, including the presence of social support, patient-friendly clinic services (transportation, co-location of services, scheduling/reminders), and positive relationships with providers and clinic staff. CONCLUSIONS: In our study, patients not retained in care faced more barriers, particularly social and structural barriers, than those retained in care. Developing care models where social and financial barriers are addressed, mental health and substance abuse treatment is integrated, and patient-friendly services are offered is important to keeping HIV-infected individuals engaged in care.

Lesbian, Gay, Bisexual, and Transgender Patient Care: Medical Students' Preparedness and Comfort.

UNLABELLED: Phenomenon: Lesbian, gay, bisexual, and transgender (LGBT) individuals face significant barriers in accessing appropriate and comprehensive medical care. Medical students' level of preparedness and comfort caring for LGBT patients is unknown. APPROACH: An online questionnaire (2009-2010) was distributed to students (n = 9,522) at 176 allopathic and osteopathic medical schools in Canada and the United States, followed by focus groups (2010) with students (n = 35) at five medical schools. The objective of this study was to characterize LGBT-related medical curricula, to determine medical students' assessments of their institutions' LGBT-related curricular content, and to evaluate their comfort and preparedness in caring for LGBT patients. FINDINGS: Of 9,522 survey respondents, 4,262 from 170 schools were included in the final analysis. Most medical students (2,866/4,262; 67.3%) evaluated their LGBT-related curriculum as "fair" or worse. Students most often felt prepared addressing human immunodeficiency virus (HIV; 3,254/4,147; 78.5%) and non-HIV sexually transmitted infections (2,851/4,136; 68.9%). They felt least prepared discussing sex reassignment surgery (1,061/4,070; 26.1%) and gender transitioning (1,141/4,068; 28.0%). Medical education helped 62.6% (2,669/4,262) of students feel "more prepared" and 46.3% (1,972/4,262) of students feel "more comfortable" to care for LGBT patients. Four focus group sessions with 29 students were transcribed and analyzed. Qualitative analysis suggested students have significant concerns in addressing certain aspects of LGBT health, specifically with transgender patients. Insights: Medical students thought LGBT-specific curricula could be improved, consistent with the findings from a survey of deans of medical education. They felt comfortable, but not fully prepared, to care for LGBT patients. Increasing curricular coverage of LGBT-related topics is indicated with emphasis on exposing students to LGBT patients in clinical settings.

Sexual and gender minority identity disclosure during undergraduate medical education: "in the closet" in medical school.

PURPOSE: To assess identity disclosure among sexual and gender minority (SGM) students pursuing undergraduate medical training in the United States and Canada. METHOD: From 2009 to 2010, a survey was made available to all medical students enrolled in the 176 MD- and DO-granting medical schools in the United States and Canada. Respondents were asked about their sexual and gender identity, whether they were "out" (i.e., had publicly disclosed their identity), and, if they were not, their reasons for concealing their identity. The authors used a mixed-methods approach and analyzed quantitative and qualitative survey data. RESULTS: Of 5,812 completed responses (of 101,473 eligible respondents; response rate 5.7%), 920 (15.8%) students from 152 (of 176; 86.4%) institutions identified as SGMs. Of the 912 sexual minorities, 269 (29.5%) concealed their sexual identity in medical school. Factors associated with sexual identity concealment included sexual minority identity other than lesbian or gay, male gender, East Asian race, and medical school enrollment in the South or Central regions of North America. The most common reasons for concealing one's sexual identity were "nobody's business" (165/269; 61.3%), fear of discrimination in medical school (117/269; 43.5%), and social or cultural norms (110/269; 40.9%). Of the 35 gender minorities, 21 (60.0%) concealed their gender identity, citing fear of discrimination in medical school (9/21; 42.9%) and lack of support (9/21; 42.9%). CONCLUSIONS: SGM students continue to conceal their identity during undergraduate medical training. Medical institutions should adopt targeted policies and programs to better support these individuals.

Sexual and Gender Minority Identity Disclosure During Undergraduate Medical Education: "In the Closet" in Medical School: MEDSCAPE 2/18/2015.

OVERVIEW: Of sexual minority respondents, 29.5% said they concealed their sexual identify in medical school. Although most (67.5%) were "out" about their identity, the authors note that this is not all that much better than the estimate of 44% 2 decades ago. (Some respondents declined to answer this question).Sexual identity concealment was lowest among gay and lesbian (14.7%) and queer (22.2%) respondents. Most bisexuals (53.9%) and questioning (92.0%) respondents reported concealing their sexual identify in medical school. PURPOSE: To assess identity disclosure among sexual and gender minority (SGM) students pursuing undergraduate medical training in the United States and Canada.

Melanoma in situ treated successfully using imiquimod after nonclearance with surgery: review of the literature.

BACKGROUND: The standard of care for melanoma in situ (MIS) is surgical removal by surgical excision with a 5-mm margin or Mohs micrographic surgery, but as more and more MIS is diagnosed in the head and neck region, surgeries may not be an option for patients when the lesions are large or less well defined. In addition, when negative margins cannot be achieved without grossly disfiguring the patient or when patients have medical comorbidities that preclude a surgical option, other treatment modalities may be considered. Recently, topical treatment with an immunomodulator, imiquimod, has been proposed as an alternative treatment for MIS. OBJECTIVE: We report a case of MIS successfully treated with topical imiquimod cream. In addition, because there has not been any comprehensive review of the use of topical imiquimod on melanoma and MIS, we conducted an extensive literature search and reviewed the topic in detail. MATERIALS AND METHODS: Using the keywords "imiquimod," "melanoma," "melanoma-in-situ," and "lentigo maligna," we searched the literature using PubMed in an attempt to find all relevant articles on the use of imiquimod on MIS or melanoma. RESULTS: There were 46 reports involving 264 patients on the use of imiquimod on MIS or lentigo maligna. Twenty-three reports were published on the use of imiquimod on metastatic melanoma involving 55 patients, and two articles were on melanoma, with two patients in total. In addition, there were two articles on the use of imiquimod on dysplastic or atypical nevi with a total of 13 subjects. CONCLUSION: Imiquimod appears to be beneficial in the treatment of MIS and melanoma metastases when surgical options are not feasible. Imiquimod should not be used for removal of dysplastic or atypical nevi. The treatment regimens varied from study to study, and there are no randomized controlled trials in the literature. More studies are needed to develop a reliable and reproducible treatment regimen, to fully elucidate the role of imiquimod in the treatment of MIS and melanoma, and to determine the prognostic predictors for favorable responses to imiquimod.

Maternal unemployment and childhood overweight: is there a relationship?

BACKGROUND: Previous studies have shown a positive association between maternal work hours and childhood overweight. However, it is unclear what role job instability plays in this relationship; therefore, this study examined whether children whose mothers experienced unemployment were more likely to have greater increases in body mass index (BMI) as compared with children whose mothers were stably employed. The effects of unemployment benefits, welfare and number of hours worked were also explored. METHODS: A multiple regression analysis was used to analyse changes in BMI over a 4-year period using the National Longitudinal Survey of Youth. In all, 4890 US children, aged 2-16 at baseline, were included in the analysis. RESULTS: As compared with children of mothers who were employed full-time and did not receive welfare, children of mothers who experienced unemployment and received unemployment benefits were not more likely to have significantly different changes in BMI. Yet children of mothers who experienced unemployment and did not receive unemployment benefits were significantly more likely to have greater increases in BMI. These results were also shown in models which controlled for height. This supports the conclusion that adiposity changes, and not simply growth-rate differences, account for the different BMI changes between groups. CONCLUSION: Aspects of maternal employment other than number of work hours are associated with child BMI, including unemployment events and what type of support a mother receives during the time of unemployment. This has implications for policies that relate to benefits for mothers who lose their jobs.

Lesbian, gay, bisexual, and transgender-related content in undergraduate medical education.

CONTEXT: Lesbian, gay, bisexual, and transgender (LGBT) individuals experience health and health care disparities and have specific health care needs. Medical education organizations have called for LGBT-sensitive training, but how and to what extent schools educate students to deliver comprehensive LGBT patient care is unknown. OBJECTIVES: To characterize LGBT-related medical curricula and associated curricular development practices and to determine deans' assessments of their institutions' LGBT-related curricular content. DESIGN, SETTING, AND PARTICIPANTS: Deans of medical education (or equivalent) at 176 allopathic or osteopathic medical schools in Canada and the United States were surveyed to complete a 13-question, Web-based questionnaire between May 2009 and March 2010. MAIN OUTCOME MEASURE: Reported hours of LGBT-related curricular content. RESULTS: Of 176 schools, 150 (85.2%) responded, and 132 (75.0%) fully completed the questionnaire. The median reported time dedicated to teaching LGBT-related content in the entire curriculum was 5 hours (interquartile range [IQR], 3-8 hours). Of the 132 respondents, 9 (6.8%; 95% CI, 2.5%-11.1%) reported 0 hours taught during preclinical years and 44 (33.3%; 95% CI, 25.3%-41.4%) reported 0 hours during clinical years. Median US allopathic clinical hours were significantly different from US osteopathic clinical hours (2 hours [IQR, 0-4 hours] vs 0 hours [IQR, 0-2 hours]; P = .008). Although 128 of the schools (97.0%; 95% CI, 94.0%-99.9%) taught students to ask patients if they "have sex with men, women, or both" when obtaining a sexual history, the reported teaching frequency of 16 LGBT-specific topic areas in the required curriculum was lower: at least 8 topics at 83 schools (62.9%; 95% CI, 54.6%-71.1%) and all topics at 11 schools (8.3%; 95% CI, 3.6%-13.0%). The institutions' LGBT content was rated as "fair" at 58 schools (43.9%; 95% CI, 35.5%-52.4%). Suggested successful strategies to increase content included curricular material focusing on LGBT-related health and health disparities at 77 schools (58.3%, 95% CI, 49.9%-66.7%) and faculty willing and able to teach LGBT-related curricular content at 67 schools (50.8%, 95% CI, 42.2%-59.3%). CONCLUSION: The median reported time dedicated to LGBT-related topics in 2009-2010 was small across US and Canadian medical schools, but the quantity, content covered, and perceived quality of instruction varied substantially.
