RESUMO

This paper describes the results of the study I Want More! The Lives of Sex Workers During the COVID-19 Pandemic, which is part of the EPIC community research program. The study analyzed the effects of the pandemic on the lives of cis, trans and travesti sex workers in nine Brazilian states and 11 cities throughout 2020 and 2021. This article focuses on the qualitative component of the study, which was based on semi-structured, remote and face-to-face interviews carried out with 43 sex workers, and its comparison with the quantitative component. The effects are analyzed in relation to the Brazilian pandemic framework, considering the social, economic and political dimensions of the COVID-19 virus. Some of the key themes of the analysis are cases of illness, specific social isolation practices, prevention and care management practices, individual vaccination and collective vaccination strategies. We also share the daily and activist responses drawn up by sex workers in a political agenda that opposes the individualistic, familialist, domestic, and neoliberal logic of isolation by adopting community care perspectives, which was the only line of health action for this work category during the pandemic. Collective actions reposition sex work at the interface between public health and human rights and take as their principle the "street knowledge", from activism, and the workers' power of decision over their own bodies.


Este trabalho apresenta os resultados do estudo Eu Quero é Mais! A Vida de Profissionais do Sexo Durante a Pandemia da COVID-19, integrante do programa de investigação comunitária EPIC. O estudo analisou os efeitos da pandemia nas vidas de trabalhadoras sexuais cis, trans e travestis em nove Unidades da Federação e 11 cidades brasileiras ao longo de 2020 e 2021. O artigo tem como foco o componente qualitativo do estudo baseado em entrevistas semiestruturadas realizadas de forma presencial e remota com 43 trabalhadoras sexuais, e seu cotejamento com o componente quantitativo. Os efeitos são analisados em relação com o marco pandêmico brasileiro, considerando as dimensões sociais, econômicas e políticas do vírus da COVID-19. Entre as temáticas chaves da análise, se destacam: casos de adoecimento, práticas localizadas de isolamento social, práticas de prevenção e gerenciamento de cuidado, vacinação individual e estratégias coletivas de vacinação. Compartilhamos também as respostas cotidianas e ativistas traçadas por trabalhadoras sexuais numa agenda política que se contrapõe à lógica individualista, familiarista, doméstica e neoliberal de isolamento, por meio de perspectivas comunitárias de cuidado, o que se desenhou como a única linha de ação em saúde para a categoria durante a pandemia. As ações coletivas reposicionam o trabalho sexual na interface entre a saúde pública e os direitos humanos e tomam como princípio os conhecimentos das ruas, desde os ativismos, e o poder de decisão delas próprias sobre seus corpos.

RESUMO

Yeast and fibrolytic enzymes serve as additives incorporated into the nutrition of ruminants to regulate rumen fermentation and increase the digestibility of fiber, thereby enhancing the efficiency of rumen fermentation. Two experiments were conducted to assess the impact of five diets: a control diet without additives, diets with yeast (Saccharomyces cerevisiae) or exogenous fibrolytic enzymes (EFE), and diets with a blend of 0.7yeast + 0.3EFE or 0.7EFE + 0.3Yeast (based on recommended levels in g/kg of total DM). In the first experiment, 40 five-month-old Santa Ines lambs (mean weight 25.0 ± 1.3 kg) were distributed in a completely randomized design (5 treatments and 8 lambs) for 81 days to evaluate performance, ingestive behaviour, and serum metabolites. In the second experiment, 25 Santa Ines male lambs weighing 25.7 ± 4.1 kg were housed in metabolic cages, in a randomized design with 5 treatments and 5 lambs, evaluating digestibility, nitrogen balance, and rumen pH. EFE supplementation increased intakes of dry matter (DM), total digestible nutrients (TDN), and apNDF (mean of 38.1, 5.26, and 27%, respectively) compared to yeast or the 0.7yeast-0.3EFE blend. Feed conversion was most efficient (mean of 27.1%) in lambs fed Yeast, 0.7EFE + 0.3yeast, and the control diet. Lambs fed 0.7yeast + 0.3EFE spent less time eating (mean of 16.5%) and more time idling (mean of 10.75%), whereas EFE-fed lambs spent more time eating (mean of 19.73%), and 0.7EFE + 0.3yeast-fed lambs spent more time ruminating (mean of 20.14%). Control group lambs chewed and ruminated less (means of 24.64 and 17.21%, respectively) compared to other treatments. Lambs on the 0.7yeast + 0.3EFE blend had higher eating and rumination efficiency rates for DM and apNDF (mean of 19.11 and 17.95%, respectively) compared to other additive treatments or individual additives. They also exhibited lower (means 7.59 g/d) urinary N excretion, with improved N retention (mean 3185 g/d) compared to the control group. There were significant effects on serum albumin and cholesterol concentrations, with the 0.7yeast + 0.3EFE blend showing higher albumin (mean 4.08 g/dL) levels, while diets without additives and yeast-EFE blends had higher cholesterol (mean of 62.51 g/dL) concentrations. Including Saccharomyces cerevisiae yeast along with 0.7 yeast + 0.3 EFE blend is recommended when feeding similar lamb diets to those used herein because it improves the efficiency of intake, rumination of DM and NDF, and nitrogen utilization without affecting the lamb performance.

RESUMO

In 2017, Morocco became the first Arab country to incorporate pre-exposure prophylaxis (PrEP) in its HIV-prevention program. Yet no research has been published on PrEP from Morocco. Although female sex workers are one of the target populations of PrEP in Morocco, their enrollment in PrEP is lower than men who have sex with men. In this study, we conducted 38 semi-structured interviews with female sex workers, physicians who prescribe PrEP, policymakers, and community advocates to identify problems associated with access to and use of PrEP. We also investigated preferences for daily oral, vaginal ring, and long-acting injectable PrEP. A reflexive thematic analysis revealed seven themes: PrEP stigma; stigmatization and criminalization of sex work; one size doesn't fit all; knowledge and misconceptions about PrEP; economic burden; inconvenience of PrEP pills; and preferred PrEP modalities. This paper discusses the implications of the findings for increasing access and use of PrEP in Morocco.


Factors that Influence Uptake of Oral PrEP among Female Sex Workers One of the most recent scientific advancements in the history of the HIV pandemic was the introduction of pre-exposure prophylaxis (PrEP). However, the uptake of PrEP in the Arab world is low. In this paper we interviewed female sex workers, physicians who prescribe PrEP, policymakers, and community advocates to identify problems associated with access to and use of PrEP. Several barriers were identified including stigma attached to PrEP, misconceptions about PrEP, and financial burden. Although most female sex workers in our study were interested in using PrEP, the delivery methods of PrEP should be tailored to fit the lifestyle and personal circumstances of potential users.

RESUMO

Little is known about the adaption of community-based organizations (CBOs) during the COVID-19 crisis. This study aimed to study how HIV CBOs and their community health workers (CHWs) faced the COVID-19 outbreak. Semi-structured interviews (n = 53) were conducted among CHWs in Burundi, Mauritania, and Lebanon in 2021. A thematic content analysis was performed. Results showed that CBOs had succeeded in maintaining HIV services and integrated COVID-19 prevention and awareness in their activities. COVID-19 led to innovation in terms of HIV services (eg, telemedicine and online psychosocial support) and to opportunities to try new modalities of antiretroviral therapy dispensation. Field workers (a specific group among CHWs) were negatively impacted by the COVID-19 crisis and showed resilience in their adaptation to ensure the continuity of their activities. Considering the essential role of field workers during the crisis, their status and the sustainability of their activities should be clearly supported by health policies and programs.


Role of community health workers during the COVID-19 pandemicThis study explores how HIV community-based organizations (CBOs) and their community health workers (CHWs) adapted during the COVID-19 pandemic. We conducted interviews with 53 CHWs from Burundi, Mauritania, and Lebanon in 2021 to understand their experiences. We found that despite the challenges posed by COVID-19, CBOs managed to continue providing essential HIV services. They also incorporated COVID-19 prevention and awareness efforts into their work. The pandemic prompted innovation, such as the use of telemedicine and online psychosocial support, and provided opportunities to explore new ways of dispensing antiretroviral therapy (ART). However, field workers, a specific group of CHWs, faced significant negative impacts due to the pandemic. Despite these challenges, they showed remarkable resilience and adapted to ensure the continuity of their services. Given the critical role of field workers during the crisis, it is important for health policies and programs to support their status and ensure the sustainability of their activities.

RESUMO

PURPOSE: To highlight the influence of preocular and ocular vascular circulatory dynamics on the vascular density (VD) of retinal capillary plexuses (RCPs) and choriocapillaris (CC) in patients with and without cardiovascular risk (CVR) factors. METHODS: A retrospective observational study in patients with and without CVR factors (type 1 and 2 diabetes, arterial hypertension, and hypercholesterolemia). Fluorescein (FA) and indocyanine (ICGA) angiography circulatory times were arterial time (FAAT), start (FAstartLF) and end (FAendLF) of laminar flow, and arterial time (ICGAAT), respectively. OCT angiography VDs were superficial (VDSCP) and deep (VDDCP) RCPs and CC (VDCC) VDs. Correlation and regression analysis were performed after adjusting for confounding factors. RESULTS: 177 eyes of 177 patients (mean age: 65.2 ± 15.9 years, n = 92 with and 85 without CVR) were included. VDSCP and VDDCP were significantly inversely correlated with FAAT, FAstartLF and FAendLF likewise VDCC with ICGAAT. Correlations were stronger in patients without CVR than with CVR. CVR, FAAT, FAstartLF and FAendLF were more strongly correlated with VDDCP than VDSCP. FAAT, FAstartLF and FAendLF significantly impacted VDSCP and VDDCP, likewise ICGAAT impacted VDDCP. VDDCP was most strongly impacted by FAAT and FAstartLF. CONCLUSION: Ocular and pre-ocular circulatory dynamics significantly impacted RCPs and CC VDs, especially deep RCP.

RESUMO

The COVID-19 crisis had a global impact and many marginalised groups, such as people who use or inject drugs, are more vulnerable to the SARS-CoV-2 virus and its consequences due to their pre-existing health inequalities. Moreover, people who use/inject drugs are also criminalised in some countries such as Algeria. This analysis aimed to explore the psychosocial experience of the COVID-19 crisis among people who use/inject drugs in Algeria. Twenty-nine qualitative interviews were conducted in 2021 with a community-based approach. Results of the thematic content analysis showed the intersectional effects of the COVID-19 crisis among people who use or inject drugs through the experience of a double crisis: one related to COVID-19 and the second to their specific difficulties related to drug use. Addressing social inequalities in health of people who use or inject drugs, through better recognition of their rights and needs, is crucial to improving their health.

RESUMO

Supplementation with CBM588, a bifidogenic live bacterial product, has been associated with improved clinical outcomes in persons with metastatic renal cell carcinoma (mRCC) receiving nivolumab and ipilimumab. However, its effect on those receiving tyrosine kinase inhibitor-based combinations is unknown. In this open-label, randomized, investigator-initiated, phase 1 study, 30 participants with locally advanced or mRCC with histological confirmation of clear cell, papillary or sarcomatoid component were randomized in a 2:1 fashion to receive cabozantinib (an inhibitor of vascular endothelial growth factor receptor, MET and AXL) and nivolumab (anti-programmed cell death protein 1) with or without CBM588 as first-line treatment. Metagenomic sequencing was performed on stool samples to characterize their gut microbiome at baseline and 13 weeks into treatment. The primary endpoint was a change in the relative abundance of Bifidobacterium spp.; secondary endpoints included objective response rate (ORR), progression-free survival (PFS) and toxicity profile. The primary endpoint of the study was not met and the addition of CBM588 to cabozantinib and nivolumab did not result in a difference in the relative abundance of Bifidobacterium spp. or alpha diversity (as measured by the Shannon index). However, ORR was significantly higher in participants treated with CBM588 compared to those in the control arm (14 of 19, 74% versus 2 of 10, 20%; P = 0.01). PFS at 6 months was 84% (16 of 19) and 60% (6 of 10) in the experimental and control arms, respectively. No significant difference in toxicity profile was seen between the study arms. Our results provide a preliminary signal of improved clinical activity with CBM588 in treatment-naive participants with mRCC receiving cabozantinib and nivolumab. Further investigation is needed to confirm these findings and better characterize the underlying mechanism driving this effect.ClinicalTrials.gov identifier: NCT05122546.

RESUMO

Many patients diagnosed with cancer adopt dietary changes and supplement use, and a growing body of evidence suggests that such modifications can affect outcomes to cancer therapy. We sought to assess the prevalence of these practices and the surrounding physician-patient dialogue among patients with metastatic renal cell carcinoma. An online survey was administered by Kidney Cancer Research Alliance (KCCure), interrogating dietary modification patterns, supplement usage, out-of-pocket expenditure related to supplements, and patients' views toward alternative medicine practices. Patients with metastatic renal cell carcinoma receiving combination therapy were actively solicited. In total, 289 unique responses were collected. The most common first-line treatments were nivolumab/ipilimumab (32.4%) and axitinib/pembrolizumab (13.1%). Within the cohort, 147 (50.9%) started using supplements following diagnosis of renal cell carcinoma; the most utilized supplements were probiotics, cannabidiol (CBD) oil/marijuana, and Vitamin C, reported by 70 (47.6%), 61 (41.4%), and 54 (36.7%), respectively. Dietary modifications following cancer diagnosis were reported by 101 (34.9%) respondents, of which 19.8% followed the Mediterranean diet and 18.8% adopted a ketogenic diet. Most respondents (71.3%) noted that they consistently report supplement usage to their physicians. A substantial proportion of patients with metastatic renal cell carcinoma utilize dietary modification and supplements as an adjunct to antineoplastic therapy. Considering the widespread adoption of these practices and the reported effects on cancer treatment, it is crucial for healthcare providers to engage in discussions with patients regarding supplement use.

RESUMO

With a national prevalence of 0.9%, Burundi is close to achieving UNAIDS' 2025 targets. Despite this, different types of crises periodically disrupt its HIV health services. The community-based program EPIC measured the impact of the COVID-19 health crisis on people living with HIV (PLHIV) in Burundi in 2021. Specifically, it assessed ART interruption and associated factors since the beginning of the pandemic. The study questionnaire was administered to PLHIV in three cities between October and November 2021. Participants were recruited using convenience sampling. Logistic regression models helped identify factors associated with ART interruption. Of the 317 respondents, 37 (11.7%) reported interruption. The majority (79.2%) self-identified as belonging to key populations. Interruption was significantly associated with: fewer HIV medical follow-up visits (adjusted Odds Ratio, aOR = 7.80, p = 0.001) and forced HIV status disclosure (aOR = 4.10, p = 0.004). It was inversely associated with multi-month ART dispensing (aOR = 0.36, p = 0.017) since the beginning of the pandemic and the perception of not having been sufficiently informed by the HIV medical team about the risk of COVID-19 infection (aOR = 0.11, p < 0.001). Our results highlight the importance of multi-month ART dispensing, enhanced communication, and voluntary disclosure of one's HIV status in preventing ART interruption in times of crises in Burundi.

RESUMO

BACKGROUND AND OBJECTIVE: The impact of time of metastasis onset with respect toprimary renal cell carcinoma (RCC) diagnosis on survival outcomes is not well characterized in the era of immune checkpoint inhibitor (ICI)-based combinations. Herein, we assessed differences in clinical outcomes between synchronous and metachronous metastatic RCC (mRCC). METHODS: Data for patients with mRCC treated with first-line ICI-based combination therapies between 2014 and 2023 were retrospectively collected. Patients were categorized as having synchronous metastasis if present within 3 mo of RCC diagnosis; metachronous metastasis was defined as metastasis >3 mo after primary diagnosis. Time to treatment failure (TTF), overall survival (OS), and the disease control rate (DCR) were assessed. KEY FINDINGS AND LIMITATIONS: Our analysis included 223 eligible patients (126 synchronous and 97 metachronous). Median TTF did not significantly differ between the synchronous and metachronous groups (9 vs 19.8 mo; p = 0.063). Median OS was significantly shorter in the synchronous group (28.0 vs 50.9 mo; p = 0.001). Similarly, patients with synchronous metachronous metastasis (58.7% vs. 78.4%; p = 0.002). On multivariable analyses, synchronous metastasis remained independently associated with worse OS and DCR. CONCLUSIONS AND CLINICAL IMPLICATIONS: In this hypothesis-generating study, patients with mRCC with synchronous metastasis who were treated with first-line ICI-based combinations have a poorer OS and worse DCR than those with metachronous mRCC. If these results are externally validated, time to metastasis could be included in prognostic models for mRCC. PATIENT SUMMARY: Our study demonstrates that patients treated with current first-line immunotherapies, who present with metastasis at the initial diagnosis of kidney cancer have worse overall survival compared to those who develop metastasis later. These results can help physicians and patients understand life expectancy.

RESUMO

Urbanization in watersheds leads to the introduction of sources of microplastics and other pollutants in water bodies. However, the effect of urbanization on microplastic pollution and the relationship between microplastics and water quality are not well understood. We assessed the distribution of microplastics in tributaries urbanized, non-urbanized and in the receiving lagoon body of Conceição Lagoon watershed. The results show that urbanization significantly affects water quality but does not differentiate tributaries in terms of microplastic concentrations. Microplastic concentrations were lower in the receiving lagoon body compared with the tributaries, highlighting their importance in microplastic pollution in the studied lagoon. Microplastic concentration was correlated with low N:P ratios in the lagoon and associated with high levels of total phosphorus, which indicate the discharge of effluents. The correlations between microplastic concentration, water temperature, and dissolved oxygen in the lagoon were based on the temporal variations of these variables. Precipitation and wind velocity had influence on microplastic distribution in the watershed. Our findings underscore the importance of evaluating water quality parameters and meteorological variables to comprehend the microplastic distribution at small watersheds.

RESUMO

Migrant men who have sex with men (mMSM) from sub-Saharan Africa (SSA) and other regions outside Europe are highly vulnerable to HIV. However, research on the determinants of HIV testing among mMSM from SSA, and how these differ across the categories of mMSM living in Europe, is limited. Using data from the European MSM Internet Survey (EMIS-2017), we assessed HIV testing prevalence and recency in mMSM from SSA and other mMSM residing in ten European countries, as well as the determinants of HIV testing across different mMSM categories with logistic regression analyses. Ever-testing for HIV was slightly higher in mMSM from SSA (83%) compared to other mMSM categories (75-80%), except for mMSM from Latin America and Caribbean region (84%). Overall, 20% of mMSM had never tested. In multivariable analysis, higher age (adjusted odds ratio [AOR] 1.05, 95% confidence interval [CI] 1.01-1.10), higher HIV knowledge (AOR 1.45, 95%-CI 1.11-1.90), and residence in smaller settlements (AOR 0.45, 95%-CI 0.21-0.96) were significantly associated with ever testing for HIV in mMSM from SSA. Comparing mMSM from SSA to mMSM from other regions, we found varying significant similarities (higher age, residence in smaller settlements and HIV knowledge) and differences (lower educational attainment, not identifying as gay, being a student, and limited disclosure of homosexual attraction) in the determinants of ever-testing for HIV. Community-specific interventions addressing identified sociodemographic and behavioral determinants to increase HIV testing uptake in the different mMSM categories and better data for further research are warranted.

RESUMO

Community-based research, that is, the meaningful involvement of affected populations in the production of scientific knowledge that concerns them, is a political struggle and an ethical necessity. Coalition PLUS, an international network of organizations (most of them NGOs) fighting against HIV and hepatitis, created a community-based research laboratory (CBRL) composed of people from more than sixteen countries and various disciplinary fields. The objectives of the CBLR are to build research capacity, ensure collaboration with local and international academic research centers, and develop international research projects. The CBRL acts as a bridge between different partners, reconciling sometimes divergent interests, and must provide mediation and support to promote dialogue, transparency, and a relationship of trust between the communities and academic researchers. However, the need for scientific legitimacy obliges us to continuously seek a balance between responding to the needs of the field and using rigorous scientific methods, while optimizing and prioritizing existing resources. The permanent quest for this balance has led the CBRL to reorganize its mode of operation to optimize existing synergies with academic research laboratories, with a view to asserting its scientific legitimacy and continuing to contribute to social transformation through community-based research that is both innovative and of high quality. This paper provides a critical reflection on the issues, challenges, practices, and solutions of community-based research within the Coalition PLUS network.

RESUMO

HIV is highly prevalent in men who have sex with men (MSM) in West Africa. Many MSM in the region also have sex with women (MSMW). Accordingly, they are a potential bridge subpopulation for HIV transmission to women. We aimed to evaluate the proportions and characteristics of West African MSMW at high behavioral risk of acquiring HIV from male partners and transmitting it to female partners (HBRMF). The cohort ANRS-12324 CohMSM Study included 630 HIV-negative MSM in Burkina Faso, Cote d'Ivoire, Mali, and Togo. Among MSMW (i.e., with ≥ 1 female partner) in the cohort, HBRMF was identified using trajectory models based on seven at-risk sexual practices with male and female partners, including inconsistent condom use, multiple partnerships, and receptive same-sex anal intercourse. To assess the relevance of using trajectory models, we compared the proportions of participants who seroconverted during the cohort follow-up among those at HBRMF and those not at HBRMF. Factors associated with HBRMF were identified using a generalized estimation equation logistic regression model accounting for longitudinal data. Approximately half (47%) of the 304 MSMW (22% of all CohMSM study participants) were at HBRMF. This group accounted for 75% of the 28 HIV seroconversions observed during follow-up (p = 0.001). HBRMF was positively associated with being aged < 25 years (aOR 95% CI 1.67 [1.23-2.27]), being sexually attracted only to men (1.97 [1.38-2.78]), feelings of loneliness (1.92 [1.38-2.65]), and homonegative violence score (1.22 [1.05-1.41]). HBRMF was negatively associated with having had both stable and casual female partners in the previous 6 months (0.34 [0.20-0.60] vs. only a stable female partner). HBRMF tended to be negatively associated with having ≥ 4 sexual intercourses with female partners in the previous four weeks (0.54 [0.27-1.06] vs. no intercourse). Establishing official relationships with women might be a strategy for young and/or stigmatized MSMW to comply with social pressure to display a heterosexual lifestyle. However, this seems to increase the risk of HIV transmission to female partners. In the present study, almost half of MSMW were at HBRMF. This result stresses the need to adapt HIV research and prevention to MSMW and their female partners.

RESUMO

OBJECTIVES: To characterise the restrictiveness of eligibility criteria in contemporary renal cell carcinoma (RCC) trials, using recommendations from the American Society of Clinical Oncology (ASCO)-Friends of Cancer Research (FCR) initiative. METHODS: vPhase I-III trials assessing systemic therapies in patients with RCC starting between 30 June 2012 and 30 June 2022 were identified. Eligibility criteria regarding brain metastases, prior or concurrent malignancies, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, and human immunodeficiency virus (HIV) infection were identified and stratified into three groups: exclusion, conditional inclusion, and not reported. Descriptive statistics were used to determine the frequency of eligibility criteria. Fisher's exact test or chi-square test were used to calculate their associations with certain trial characteristics. RESULTS: A total of 423 RCC trials were initially identified of which 112 (26.5%) had sufficient accessible information. Exclusion of patients with HIV infection, HBV/HCV infection, brain metastases, and prior or concurrent malignancies were reported in 74.1%, 53.6%, 33.0%, and 8.0% of trials, respectively. In the context of HIV and HBV/HCV infection, patients were largely excluded from trials evaluating immunotherapy (94.4% and 77.8%, respectively). In addition, brain metastases were excluded in trials assessing targeted therapy (36.4%), combined therapy (33.3%), and immunotherapy (22.2%). Exclusion of patients with prior or concurrent malignancies was less frequently reported, accounting for 9.1%, 8.3%, and 5.6% targeted therapy, combined therapy and immunotherapy trials, respectively. CONCLUSION: A substantial proportion of RCC trials utilise restrictive eligibility criteria, excluding patients with fairly prevalent comorbidities. Implementing the ASCO-FCR recommendations will ensure resulting data are more inclusive and aligned with patient populations in the real-world.

RESUMO

Despite PrEP being available and free of charge in France, a gap remains between the estimated number of men who have sex with men (MSM) with high-risk exposure to HIV and the number of MSM PrEP users. The objective of this study is to identify factors associated with non-intention to use PrEP among PrEP-eligible and PrEP-aware MSM in France, "non-intenders".European MSM Internet Survey (EMIS)-2017 was a cross-sectional survey conducted among MSM concerning their HIV prevention needs. Logistic regression models were used to identify factors associated with "non-intenders".Compared to PrEP users, factors associated with non-intention to use PrEP were: age (aOR[95%CI] = 3.80[2.21;6.53]); not being vaccinated against hepatitis B (2.20[1.45;3.34]); self-efficacy (1.84[1.29;2.60]); lower knowledge about on-demand PrEP (11.48[7.37;17.87]) and daily PrEP (2.58[1.27;5.25]); not having a PrEP discussion at a hospital (12.39[8.90;17.27]) or at a community service/drop-in (4.93[3.48;6.97]); living in a department with few PrEP access points (1.70[1.10;2.63]).On-demand PrEP may meet the prevention needs of "non-intenders" who have lower HIV risk perception. Increasing communication from health providers and community health workers to all MSM is needed.

RESUMO

BACKGROUND: Information concerning the impact of the COVID-19 health crisis on populations most affected by HIV and hepatitis C virus (HCV; or key populations [KP]), and those working with these populations in community settings, is limited. Community-based organizations working in the field of HIV and viral hepatitis are well placed to identify and meet the new needs of KP owing to the health crisis. OBJECTIVE: This study aims to describe the development and implementation of an exploratory and descriptive multicountry, community-based research program, EPIC (Enquêtes Pour évaluer l'Impact de la crise sanitaire covid en milieu Communautaire), within an international network of community-based organizations involved in the response to HIV and viral hepatitis. The EPIC program aimed to study the impact of the COVID-19 health crisis on KP or people living with HIV or HCV and people working with these populations at the community level (community health workers [CHWs]) and to identify the key innovations and adaptations in HIV and HCV services. METHODS: A general protocol and study documents were developed and shared within the Coalition PLUS network. The protocol had a built-in flexibility that allowed participating organizations to adapt the study to local needs in terms of the target population and specific themes of interest. Data were collected using surveys or interviews. RESULTS: From July 2020 to May 2022, a total of 79 organizations participated in the EPIC program. Across 32 countries, 118 studies were conducted: 66 quantitative (n=12,060 among KP or people living with HIV or people living with HCV and n=811 among CHWs) and 52 qualitative (n=766 among KP or people living with HIV or people living with HCV and n=136 among CHWs). CONCLUSIONS: The results of the EPIC program will provide data to describe the impact of the health crisis on KP and CHWs and identify their emerging needs. Documentation of innovative solutions that were put into place in this context may help improve the provision of services after COVID-19 and for future health crises.

RESUMO

Introducción: La pandemia de COVID-19 afectó significativamente al personal de salud, los estudiantes de medicina tuvieron alta exposición a la infección y reinfección. El objeto del estudio fue determinar la infección y reinfección por SARS-Cov-2 y la cobertura vacunal en los estudiantes de medicina de 1ro a 6to año en el período de enero-febrero 2023. Metodología: Estudio de corte transversal por encuesta vía electrónica. Muestra aleatoria polietápica por azar simple y conglomerados estratificados por nivel académico. Proyecto avalado por La Comisión Nacional de Bioética. Resultados: Se recolectaron 224 respuestas, reportando 334 episodios de infección por SARS-CoV-2, 19 % presentó al menos un episodio de infección en 2020, 40 % en 2021 y 41 % en 2022. El 75,4 % reportó haber estado infectado y reinfectado; de estos, el 70 % presentó entre 2 y 5 reinfecciones. En el 37 % de los episodios se confirmó, por reacción en cadena polimerasa (PCR, por sus siglas en inglés) o prueba de antígenos. Los estudiantes de internado rotatorio y 5to año se infectaron más que los de 1ro a 3er año (p= 0,0037). La vacunación alcanzó 96 % de los estudiantes, la mayoría recibió 2 o más dosis de refuerzo, los alumnos de 4to a 6to año con un número mayor de dosis (p= 0,0067). Las hospitalizaciones fueron bajas 4 %. Conclusiones: las infecciones y reinfecciones son frecuentes en los estudiantes de medicina; la mayoría no presenta complicaciones graves, los estudiantes del área clínica están más expuestos y están mayormente vacunados, que los estudiantes de preclínica.


Introduction: The COVID-19 pandemic significantly impacted healthcare personnel, with medical students having high exposure to infection and reinfection. The study aimed to determine the infection and reinfection rates of SARS-CoV-2 and the vaccination coverage among medical students from 1st to 6th year during the period of January-February 2023. Methodology: This was a cross-sectional study using an electronic survey. A multi-stage random sample was taken with simple random sampling and clusters stratified by academic level. The project was approved by the National Bioethics Commission. Results: A total of 224 responses were collected, reporting 334 episodes of SARS-CoV-2 infection. Nineteen percent reported at least one episode of infection in 2020, 40 % in 2021, and 41 % in 2022. Seventy-five point four percent reported having been infected and reinfected; of these, 70 % had between 2 and 5 reinfections. In 37 % of the episodes, the infection was confirmed by polymerase chain reaction (PCR) or antigen test. Internship students and 5th-year students were more infected than those in 1st to 3rd year (p=0.0037). Vaccination coverage reached 96 % of the students, with most receiving 2 or more booster doses; students in the 4th to 6th years had a higher number of doses (p=0.0067). Hospitalizations were low at 4 %. Conclusions: Infections and reinfections are frequent among medical students; most do not present severe complications. Clinical area students are more exposed to infection and are more vaccinated compared to preclinical students.
