Despite potentially devastating complications, free foreign substance injections for feminizing breast augmentation remain common among transgender women. To date, the literature regarding surgical treatment of these deformities among transgender women remains limited. The authors present a case series of transgender women presenting for surgical management of granulomatous breast deformities secondary to free foreign substance injections between January of 2016 and February of 2020. Seven transgender women presented for surgical management of complications secondary to free foreign substance injections of the breast. These patients ranged in age from 29 to 53 years, all identified as Hispanic/Latinx, and five were primarily Spanish speakers. All were recipients of public insurance. Six of the seven patients received free foreign substance injections outside of the United States, with an average time from initial injections to presentation of 19.3 ± 15.7 years. Three patients presented with a history of prior revisions by other surgeons. Four underwent staged reconstruction at the authors' institutions. Patients were followed for, on average, 10.7 ± 12.6 months after their initial surgery. There were no major complications. The most common minor complication was delayed wound healing. In the present series, the authors illustrate that, with careful consideration and patient selection, it is possible to perform safe and successful breast reconstruction for the management of foreign substance granulomas in transgender women. They also provide an algorithm based on patient-specific factors to guide treatment decisions in this patient population. Further research is needed to determine the generalizability and applicability of this algorithm.Therapeutic, IV.

Leadership development programs are integral to the future success of public health and healthcare organisations. Despite low-and middle-income countries (LMICs) bearing a greater burden of unmet medical needs, fewer professional development opportunities exist in these settings. This study aims to provide a comprehensive understanding of available leadership development programs for healthcare professionals in LMICs.This study conforms to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis-P systematic review and traditional meta-analyses guidelines. Articles were identified through five academic databases: Embase, PubMed, Web of Science, ERIC, and Business Source Complete. Eligibility criteria included original research published in peer-reviewed journals on non-clinical, leadership development programs offered to healthcare professionals in LMICs worldwide.Forty-one peer-reviewed articles met inclusion criteria, of which physicians, nurses, and public health professionals were the most common types of providers to attend leadership development programs; no programs exclusively targeted surgeons. The greatest proportion of programs were short-term interventions (ranging from 1 day to 12 weeks). Communication, organizational structure and leadership, and personal development were identified as the three most common leadership themes in the review. Regionally, leadership programs were reported most commonly in Africa, specifically in Anglophone countries. Other regions worldwide, including Latin America and the Caribbean, were underrepresented in the review.The findings from this review identify gaps in leadership development programs for certain groups of healthcare professionals from certain geographical regions, supporting the need for further provision of and participation in these opportunities in LMICs.

Background Firearm violence is a unique public health crisis in the USA (US). A majority of U.S. physicians believe they should discuss firearm safety with patients. However, little education on firearm injury prevention and counseling exists in medical school. We sought to address this gap by creating a curriculum on firearm violence as a part of a required preclinical medical school course focused on health policy issues. Methods The Kerns 6-step model for curriculum development was used to define the problem and assess learner needs. The two-hour small group session was co-authored by a student and faculty member to address the course theme of health policy as applied to firearm violence. The Issue-Attention Cycle, history of firearm policy, and US politics were incorporated from published literature, with a patient counseling role-play added in 2019. Results The ‘Current Case in Health Policy – Firearm Violence’ small group was implemented in 2018 and 2019 for all first-year medical students. Of the 2018 student evaluations, 57% selected this small group as the most valuable in the course. In a follow-up survey in 2020, 78% of the respondents agreed that they felt more confident counseling patients on firearm safety following the role-play. Conclusion Students broadly endorsed the incorporation of firearm policy and counseling skills into medical education. This curriculum can be adapted for learners at all stages of training, especially given the limited exposure to this topic in medical education.

This study investigated the association of HIV infection and cocaine dependence with cerebral white matter integrity using diffusion tensor imaging (DTI). One hundred thirty-five participants stratified by HIV and cocaine status (26 HIV+/COC+, 37 HIV+/COC-, 37 HIV-/COC+, and 35 HIV-/COC-) completed a comprehensive substance abuse assessment, neuropsychological testing, and MRI with DTI. Among HIV+ participants, all were receiving HIV care and 46% had an AIDS diagnosis. All COC+ participants were current users and met criteria for cocaine use disorder. We used tract-based spatial statistics (TBSS) to assess the relation of HIV and cocaine to fractional anisotropy (FA) and mean diffusivity (MD). In whole-brain analyses, HIV+ participants had significantly reduced FA and increased MD compared to HIV- participants. The relation of HIV and FA was widespread throughout the brain, whereas the HIV-related MD effects were restricted to the corpus callosum and thalamus. There were no significant cocaine or HIV-by-cocaine effects. These DTI metrics correlated significantly with duration of HIV disease, nadir CD4+ cell count, and AIDS diagnosis, as well as some measures of neuropsychological functioning. These results suggest that HIV is related to white matter integrity throughout the brain, and that HIV-related effects are more pronounced with increasing duration of infection and greater immune compromise. We found no evidence for independent effects of cocaine dependence on white matter integrity, and cocaine dependence did not appear to exacerbate the effects of HIV.

South Africa is experiencing a growing methamphetamine problem, and there is concern that methamphetamine use may accelerate HIV transmission. There has been little research on the HIV prevention needs of methamphetamine users receiving substance abuse treatment in South Africa. This study assessed the prevalence and correlates of HIV risk behaviors among 269 methamphetamine users entering substance abuse treatment in two clinics in Cape Town. The prevalence of sexual risk behaviors was high among sexually active participants: 34 % multiple partners, 26 % unprotected intercourse with a casual partner, and 24 % sex trading for money/methamphetamine. The strongest predictor of all sexual risk behaviors was concurrent other drug use. Over half had not been HIV tested in the past year, and 25 % had never been tested, although attitudes toward HIV testing were overwhelmingly positive. This population of primarily heterosexual, non-injecting methamphetamine users is a high-risk group in need of targeted HIV prevention interventions. Substance abuse treatment is an ideal setting in which to reach methamphetamine users for HIV services.

HIV infection can cause direct and indirect damage to the brain and is consistently associated with neurocognitive disorders, including impairments in decision-making capacities. The tendency to devalue rewards that are delayed (temporal discounting) is relevant to a range of health risk behaviors. Making choices about delayed rewards engages the executive control network of the brain, which has been found to be affected by HIV. In this case-control study of 18 HIV-positive and 17 HIV-negative adults, we examined the effects of HIV on brain activation during a temporal discounting task. Functional MRI (fMRI) data were collected while participants made choices between smaller, sooner rewards and larger, delayed rewards. Choices were individualized based on participants' unique discount functions, so each participant experienced hard (similarly valued), easy (disparately valued), and control choices. fMRI data were analyzed using a mixed-effects model to identify group-related differences associated with choice difficulty. While there was no difference between groups in behavioral performance, the HIV-positive group demonstrated significantly larger increases in activation within left parietal regions and bilateral prefrontal regions during easy trials and within the right prefrontal cortex and anterior cingulate during hard trials. Increasing activation within the prefrontal regions was associated with lower nadir CD4 cell count and risk-taking propensity. These results support the hypothesis that HIV infection can alter brain functioning in regions that support decision making, providing further evidence for HIV-associated compensatory activation within fronto-parietal cortices. A history of immunosuppression may contribute to these brain changes. Hum Brain Mapp 37:2455-2467, 2016. © 2016 Wiley Periodicals, Inc.

Author(s): Kesavan, Kalpashri; Frank, Paul; Cordero, Daniella M; Benharash, Peyman; Harper, Ronald M | Abstract: BackgroundApnea of Prematurity (AOP) is common, affecting the majority of infants born at l34 weeks gestational age. Apnea and periodic breathing are accompanied by intermittent hypoxia (IH). Animal and human studies demonstrate that IH exposure contributes to multiple pathologies, including retinopathy of prematurity (ROP), injury to sympathetic ganglia regulating cardiovascular action, impaired pancreatic islet cell and bone development, cerebellar injury, and neurodevelopmental disabilities. Current standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and methylxanthine therapy; these interventions are inadequate, and not optimal for early development.ObjectiveThe objective is to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements trigger reflexive facilitation of breathing.MethodsPremature infants (23-34 wks gestational age), with clinical evidence of AOP/IH episodes were enrolled 1 week after birth. Caffeine treatment was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in 6 hour ON/OFF sequences for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2), and breathing pauses were continuously collected.ResultsFewer respiratory pauses occurred during vibration periods, relative to baseline (pl0.005). Significantly fewer SpO2 declines occurred with vibration (pl0.05), relative to control periods. Significantly fewer bradycardic events occurred during vibration periods, relative to no vibration periods (pl0.05).ConclusionsIn premature neonates, limb proprioceptive stimulation, simulating limb movement, reduces breathing pauses and IH episodes, and lowers the number of bradycardic events that accompany aberrant breathing episodes. This low-cost neuromodulatory procedure has the potential to provide a non-invasive intervention to reduce apnea, bradycardia and intermittent hypoxia in premature neonates.Trial registrationClinicalTrials.gov NCT02641249.
