RESUMEN

BACKGROUND: Initiatives employing medical students' volunteerism and idealism, such as the Student-Run Free Clinics (SRFC) program, are prevalent in US medical schools. Many studies evaluated various aspects of volunteering, sometimes resulting in conflicting evidence. This study simultaneously sought to identify the characteristics of volunteers vs. non-volunteers, and to characterize the volunteers' perception of the SRFC. METHODS: We administered a survey to the Long School of Medicine (LSOM) Class of 2018 before their third year of medical school. The authors compared and contrasted the findings of the SRFC volunteers with their non-volunteering counterparts by analyzing their demographics, volunteering history, academic performance, and clinical skills. The volunteers were also asked about their SRFC experiences. RESULTS: While most volunteers were female (62 %) and non-traditional students (67 %), the difference was not statistically significant (p = 0.15 and p = 0.38, respectively). Additionally, there were no statistically significant differences between the two groups in measures of academic performance (p = 0.25). Most of the volunteers learned about the SRFC program prior to starting medical school. Further, while SRFC volunteers were more likely to engage in additional local volunteering initiatives, the difference was not statistically significant (p = 0.03, prespecified  α= 0.006). Importantly, volunteers agreed/strongly agreed that SRFC volunteering emphasized aspects that were missing or underemphasized in the formal medical school curriculum. CONCLUSIONS: Medical students' age, gender, undergraduate major, and non-traditional status were not statistically different between volunteers vs. non-volunteers. However, there may be tendencies for volunteers to be female, non-traditional, and locally engaged. Further, the timing of knowledge of the SRFC program may not affect student involvement in the SRFC, either. Most importantly, however, while volunteering does not affect the students' academic performance, it may provide improvements in clinical competencies.

RESUMEN

We designed and implemented a collaborative immersion in Ethiopia as a service learning experience for a team of interprofessional (IP) learners. The IP team of four dental students, one dental faculty, nine medical students, two medical student leaders, and one global health faculty fully experienced this immersion. The setting was in rural Ethiopia, and the immersive experience included ecological accommodations by the Common River Non-Governmental Organization (CR-NGO).

RESUMEN

Educational efforts to reduce global rates of adolescent pregnancy vary widely with a significant deficiency found in the domain of sex education facilitator training. In this study, we sought to establish a pilot approach to comprehensive sex education facilitator training as applied in Riobamba, Ecuador. The approach was aligned with UNESCO recommendations for training facilitators using an adapted version of the U.S.-based Big Decisions curriculum. Four internationally recruited bilingual instructors led a six-day (27-hour) intensive training-of-facilitators programme with twenty trainees using the Big Decisions sex education curriculum. Quantitative and qualitative analyses were conducted using various approaches: anonymised and pre/post-self-assessments, daily feedback surveys of self and instructors, and facilitation practice evaluations. Responses to anonymised surveys indicated improved self-perceived confidence in teaching each curriculum section. More objective pre- and post-teach-back evaluations showed improved ability to teach randomly assigned lessons as assessed by trainers. The pedagogy of facilitator training in comprehensive sex education seeks to combine evidence-informed and culturally appropriate approaches to training facilitators under unique local conditions using adapted assessment tools. This project revealed important culturally relevant insights that would be beneficial to the future training of comprehensive sex education facilitators working within culturally conservative communities, and Latin America in particular.

RESUMEN

Introduction: COVID-19 challenged our healthcare systems and unsurprisingly, so did its vaccine. Chief among these were the uniquely politicized nature and logistical difficulties surrounding its deployment. Understanding provider attitudes toward the COVID-19 vaccines and their willingness/ability to deliver them is essential to developing an ideal vaccine distribution plan for Bexar County, Texas. Methods: An electronic survey was sent to providers serving adult patients across Bexar County. Membership includes representation from local hospitals, Bexar County Medical Society, and the San Antonio Metropolitan Health District's vaccination program. The survey measured provider attitudes toward the vaccines and asked logistical questions regarding patient hesitancy and clinic infrastructure. Results: Responses were collected from 66 ZIP codes (90% of ZIP codes in the county), and 377 providers answered the survey. Respondents who were unlikely to recommend the vaccine (3%) shared concerns involving distrust of the vaccine manufacturing process. Recommendations made by physicians to support their vaccine administration efforts included broadening the reporting timeframe (n=35), providing trained support staff (n=18), and improving logistical support (n=14). Furthermore, responses showed that only 14.44% of provider facilities were able to meet originally published refrigeration requirements to store Pfizer's vaccines compared with 87.47% for Moderna's vaccines. Conclusions: Survey results were used to improve the efficiency of vaccination programs and address vaccine hesitancy through various avenues of information delivery. It is recommended to replicate the outcomes and applications of this study in other populations to improve the efficiency of vaccination programs and reduce vaccine hesitancy.

RESUMEN

PROBLEM: Residents may experience mistreatment by faculty, peers, nurses, or patients. While faculty are reportedly the primary contributors to mistreatment, residents can also be offenders, which merits study. Forum theatre (FT) is an experiential learning modality requiring a peer group to develop problem-solving strategies. FT was piloted to address mistreatment among residents. The objective was to determine whether FT was feasible, acceptable to resident learners, and could lead to self-reported changes in perceptions or behaviors, providing program directors a focused option to address professionalism as a competency. APPROACH: This initiative was conducted from September 2019 through February 2021 in obstetrics-gynecology and urology residencies at UT Health San Antonio and consisted of 3 phases: a focus group to identify mistreatment experienced by residents, resident volunteers to create and act out the FT scenario, and enactment of the FT scenario during didactic time. Residents completed anonymous retrospective pre- and postsurveys, as well as at 6-8 months after, to assess knowledge, attitudes, and self-reported and observed behaviors. Wilcoxon rank-sum tests and 2-sample t tests for proportions were used to compare variables between groups. OUTCOMES: The FT was completed successfully in both departments during didactic time. Twenty-six residents participated, 24 (92%) responded. Most respondents (23, 96%) would recommend FT to colleagues for teaching professionalism. Behavior changes were reported by 15 (63%) participants after the program. After 6-8 months, self-reported mistreatment behaviors had decreased, including "making fun of others" (15 (63%) to 10 (38%), P = .04) and sending "disparaging texts" (13 (54%) to 7 (27%), P =.02). NEXT STEPS: The use of FT during regularly scheduled didactic times was feasible and well received among residents. The evaluation demonstrated sustained self-reported behavior changes. Plans are ongoing to expand this approach to other medical specialties and professions institutionally.

RESUMEN

Suppression of dendritic cell function in cancer patients is thought to contribute to the inhibition of immune responses and disease progression. Molecular mechanisms of this suppression remain elusive, however. Here, we show that a fraction of blood monocyte-derived myeloid dendritic cells (MDCs) express B7-H1, a member of the B7 family, on the cell surface. B7-H1 could be further upregulated by tumor environmental factors. Consistent with this finding, virtually all MDCs isolated from the tissues or draining lymph nodes of ovarian carcinomas express B7-H1. Blockade of B7-H1 enhanced MDC-mediated T-cell activation and was accompanied by downregulation of T-cell interleukin (IL)-10 and upregulation of IL-2 and interferon (IFN)-gamma. T cells conditioned with the B7-H1-blocked MDCs had a more potent ability to inhibit autologous human ovarian carcinoma growth in non-obese diabetic-severe combined immunodeficient (NOD-SCID) mice. Therefore, upregulation of B7-H1 on MDCs in the tumor microenvironment downregulates T-cell immunity. Blockade of B7-H1 represents one approach for cancer immunotherapy.

RESUMEN

The Community Health Club (CHC) model is a community-based health promotion program that utilizes water, sanitation, and hygiene (WASH) education as the first stage of a longitudinal development process. Although the CHC model has been implemented in fourteen countries over 20 years, this is the first review of the literature describing the model's outcomes and impact. We conducted a review of the literature that provided quantitative or qualitative evidence of CHC interventions focused on WASH in low- and middle-income countries. We identified 25 articles that met our inclusion criteria. We found six major outcomes: WASH behaviors and knowledge, social capital, collective action, health, and cost or cost-effectiveness. The most consistent evidence was associated with WASH behaviors and knowledge, with significant effects on defecation practices, hand washing behaviors, and WASH knowledge. We also found qualitative evidence of impact on social capital and collective action. CHCs catalyze favorable changes in WASH behaviors and knowledge, yielding outcomes commensurate with other WASH promotion strategies. This review provides insights into the model's theory of change, helping identify areas for further investigation. The CHC model's holistic focus and emphasis on individual and collective change offer promising potential to address multiple health and development determinants.

RESUMEN

Misinformation and promotion of well-intended but disproved therapies for COVID-19 have plagued evidence-based shared decision-making throughout the COVID-19 pandemic. In times of crisis, clinicians may feel that their strong inclination to prescribe potentially harmful, unproven therapies on behalf of their patients is supported by beneficence. Clinicians should mindfully identify and avoid commission bias during this pandemic, especially as more data have accumulated to assist with clinically sound decision-making. We describe a more evidence-based approach to treatment of early outpatient COVID-19, stressing the availability of Food and Drug Administration emergency use authorization therapies and considering plausibly beneficial, nonprescription supplements that are generally regarded as safe.

RESUMEN

We conducted a retrospective chart review of human immunodeficiency virus (HIV)-infected patients who died in 1995 and in 1999-2000. We found an increase in the proportion of patients who died from an illness that was not related to acquired immunodeficiency syndrome (AIDS). Although there was a decrease in the prevalence of AIDS-defining illnesses, >85% of patients died with CD4 counts of <200 cells/microL. The leading cause of death was Pneumocystis carinii pneumonia (PCP). Nonadherence to therapy and new diagnosis of HIV infection were the leading reasons why patients were not receiving antiretroviral therapy. The leading causes of non-AIDS-related deaths in 1999-2000 were non-AIDS-defining infections and end-stage liver disease. At our hospital, PCP remains an important cause of death in the highly active antiretroviral therapy (HAART) era, possibly because >50% of HIV-infected patients who died were not receiving HAART. AIDS-defining illnesses continue to be a major cause of mortality in the HAART era in populations where access to care and adherence to HAART is limited.

RESUMEN

Rheumatologists are increasingly asked to see patients with hepatitis C who exhibit a variety of clinical and serologic features that mimic systemic rheumatic disease. Treatment with interferons, now the standard of care, can precipitate a variety of inflammatory conditions, including sarcoidosis. We present a case of a 59-year-old former intravenous drug user who developed systemic sarcoidosis while receiving interferon alpha and ribavirin for the treatment of chronic hepatitis C. Because interferons are increasingly prescribed by specialists in a variety of disciplines, rheumatologists should be aware of their potential to induce sarcoidosis as well as various autoimmune diseases.

RESUMEN

Renal electrolyte disorders, acute renal failure, and a variety of chronic renal diseases are common in HIV-infected patients. Glomerular disorders include IgA nephropathy, cryoglobulinemia, amyloidosis, and a lupus-like immune complex glomerulopathy. The most attention has been focused on collapsing glomerulopathy associated with nephrotic syndrome and progressive renal failure, which appears to be unique for patients with HIV/AIDS, called HIV-associated nephropathy (HIVAN), and it occurs predominantly in African American patients. Investigations in humans and in a transgenic mouse model reveal direct infection of renal epithelial cells by HIV and toxic cellular and immunologic processes mediated by HIV glycoproteins as the principal pathophysiology of HIVAN. Highly active antiretroviral treatment may be associated with an improved renal outcome and even reversal of kidney disease in some patients. Treatment with angiotensin-converting enzyme inhibitors may avert progression of HIVAN to end-stage kidney disease and result in superior patient and kidney survival as compared with untreated patients.

RESUMEN

Pseudallescheria boydii is a ubiquitously occurring fungus. While rarely causing opportunistic infection in humans, it is the most common cause of fungal pneumonia in cases of near drowning, and is associated with high mortality. P. boydii typically causes cutaneous mycetomas but may invade the lungs or brain. P. boydii infections are difficult to treat due to amphotericin B resistance and frequent need for surgical resection. Zygomycetous infections, often referred to as "mucormycoses," usually occur in immunocompromised hosts, trauma or burn victims. Like P. boydii, these organisms are found on decaying vegetation and in soil. Zygomycetous infections generally require debridement and prolonged amphotericin B. We report a case of P. boydii pneumonia with a simultaneous brain lesion and cutaneous mucormycosis in a near drowning patient. The pneumonia responded to treatment with voriconazole and the brain lesion resolved without surgery. The cutaneous mucormycosis responded to surgery and amphotericin B. This is the first documented case of simultaneous invasive P. boydii and cutaneous mucormycosis successfully treated with dual systemic antifungal therapy and resection.

RESUMEN

Among HIV-infected persons, chronic hepatitis C virus (HCV) infection causes substantial morbidity and mortality. However, few studies have evaluated the safety and efficacy of interferon alfa (IFN) and ribavirin (RBV) therapy in co-infected persons. Accordingly, a randomized, controlled, open-label, multicenter trial was conducted to establish the safety, tolerability, and efficacy of IFN alfa-2b 3 mIU daily plus RBV 800 mg/d compared with IFN alfa-2b 3 mIU thrice weekly (TIW) plus RBV 800 mg/d in HCV treatment-naive, HIV-infected subjects with compensated liver disease and stable HIV disease. The primary endpoint was sustained virologic response (SVR), defined as an undetectable HCV RNA level 24 weeks after discontinuation of HCV therapy. At study entry, subjects in both groups were similar with respect to age, gender, HCV genotype, and HIV disease status. Of 180 randomized subjects, 162 received at least 1 dose of study medication, constituting the modified intention-to-treat population. After 12 weeks of therapy, 122 (75%) had serum HCV RNA levels assessed; of these subjects, early virologic response (undetectable HCV RNA or >2 log10 decrease from baseline) was observed in 33 (42%) and 13 (16%) of subjects taking daily and TIW IFN, respectively (P < 0.001). SVR was observed in 15 (19.0%) and 7 (8.4%) of subjects taking daily and TIW IFN, respectively (P = 0.05). Adverse events were similar in both groups. However, while no deaths or opportunistic infections were observed, nearly 30% of subjects stopped treatment due to adverse events and 7 subjects experienced a serious adverse event. In conclusion, SVR was achieved in 19% of HIV/HCV coinfected subjects treated with daily IFN plus RBV, but the effectiveness of therapy was substantially diminished by relatively high rates of treatment-related toxicity.

RESUMEN

Performing a liver biopsy in patients infected with HIV and hepatitis C virus (HCV) is considered the standard of practice to assess hepatic involvement but carries risks to patients. This pilot study was designed to identify single photon emission computed tomography (SPECT) parameters that correlate with liver disease stage. HIV-coinfected and HCV-coinfected individuals undergoing a liver biopsy had a SPECT scan performed. The results showed that a number of SPECT parameters were associated with histologic changes in architecture, fibrosis, and cirrhosis, of which two SPECT parameters, the minimum pixel count for spleen region of interest and maximum pixel count for right hepatic lobe, correctly classified 39 of 46 SPECT/biopsy pairs. In conclusion, this pilot trial identified SPECT parameters that correlated with liver histology changes. A larger study is needed to demonstrate whether SPECT parameters alone or with other markers can provide information on fibrosis with the clinical significance obtained through liver biopsy.
