RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has disrupted multiple health services, including human immunodeficiency virus (HIV) testing, care, and treatment services, jeopardizing the achievement of the Joint United Nations Programme on HIV/AIDS 90-90-90 global target. While there are limited studies assessing the impact of the COVID-19 pandemic on people living with HIV (PLHIV) in Latin America, there are none, to our knowledge, in Venezuela. This study aims to assess the impact of the COVID-19 pandemic among PLHIV seen at the outpatient clinic of a reference hospital in Venezuela. METHODS: We conducted a cross-sectional study among PLHIV aged 18 years and over seen at the Infectious Diseases Department of the University Hospital of Caracas, Venezuela between March 2021 and February 2022. RESULTS: A total of 238 PLHIV were included in the study. The median age was 43 (IQR 31-55) years, and the majority were male (68.9%). Most patients (88.2%, n = 210) came for routine check-ups, while 28 (11.3%) were newly diagnosed. The majority of patients (96.1%) were on antiretroviral therapy (ART), but only 67.8% had a viral load test, with almost all (95.6%) being undetectable. Among those who attended regular appointments, 11.9% reported missing at least one medical consultation, and 3.3% reported an interruption in their ART refill. More than half of the patients (55.5%) had received at least one dose of the COVID-19 vaccine, while the rest expressed hesitancy to get vaccinated. Most patients with COVID-19 vaccine hesitancy were male (65.1%), younger than 44 years (57.5%), employed (47.2%), and had been diagnosed with HIV for less than one year (33%). However, no statistically significant differences were found between vaccinated patients and those with COVID-19 vaccine hesitancy. Older age was a risk factor for missing consultations, while not having an alcoholic habit was identified as a protective factor against missing consultations. CONCLUSION: This study found that the COVID-19 pandemic had a limited impact on adherence to medical consultations and interruptions in ART among PLHIV seen at the University Hospital of Caracas, Venezuela.

RESUMO

International migration is increasingly characterized by the need to evade threats to survival. Nevertheless, demographic understandings of how families-rather than individuals alone-decide to migrate or separate in response to threats remain limited. Focusing on the recent humanitarian crisis in Venezuela, we analyze 2012-2016 data on Venezuelans in Venezuela and 2018-2020 data on UNHCR (United Nations High Commissioner for Refugees)-registered Venezuelans in nine receiving countries to illuminate the evolution of threats Venezuelans sought to evade, how threat evasion transformed households away from previous norms, the selection of migrants into different receiving countries and household structures, and demographic disparities in migrants' odds of reporting changes to their household because of specific migration-related processes (e.g., leaving someone in Venezuela, leaving someone in another country). Results underscore a simultaneous escalation of economic, safety, and political concerns that informed Venezuelans' increasing intentions to out-migrate. Where Venezuelans migrated and who ended up in their households abroad varied by demographic background and migration experiences. Among UNHCR-registered Venezuelans, 43% left family members in Venezuela, and more than 10% left or were left behind by members in another country. Such household separations, however, were unevenly distributed across factors such as age, gender, and country of reception.

RESUMO

BACKGROUND: Despite nearly a quarter of Venezuelans remaining unvaccinated against coronavirus disease 2019 (COVID-19), the factors contributing to vaccine hesitancy in the country have not been thoroughly investigated. METHODS: A cross-sectional study was conducted from October 15th to 30th, 2022, using a knowledge, attitudes, and practices (KAP) survey to identify factors associated with COVID-19 vaccine hesitancy. RESULTS: The study analyzed data from 1,930 participants from all 24 states of Venezuela. The majority (93.4%) were vaccinated. The mean age was 40 years, predominantly female (67.3%), and held a university degree (70.6%). The mean KAP score was significantly higher among vaccinated individuals compared to unvaccinated ones (7.79 vs. 3.94 points for knowledge, 40 vs. 24 points for attitudes, and 16 vs. 10 points for practices, all p < 0.001). Increases in the scores for KAP were associated with increased odds of being vaccinated (84.6%, 25.6%, and 33% respectively for each one-point increase, all p < 0.001). Certain demographic factors such as marital status, occupation, religious beliefs, monthly income, and location influence COVID-19 vaccine knowledge. Higher income and certain occupations decrease the odds of low knowledge, while residing in specific states increases it. Attitudes towards the COVID-19 vaccine are influenced by age, health status, vaccination status, and location. Higher income and absence of certain health conditions decrease the odds of negative attitudes. Lastly, age, occupation, monthly income, and location affect vaccine practices. Advanced age and higher income decrease the odds of inappropriate practices, while residing in La Guaira state increases them. CONCLUSION: Factors such as age, education level, occupation, monthly income, and location were found to be associated with knowledge and attitudes towards COVID-19 vaccine among the surveyed Venezuelans.

RESUMO

BACKGROUND: The last decade saw the emergence of a new significant migration corridor due to the mass migration of Venezuelans to neighboring countries in South America. Since 2018, Brazil became the third host country of Venezuelan displaced populations. Little is known about how migratory processes affect needs, access to social programs, and public health services of migrant women. The goal of this study is to shed light on the socio-economic profile, living conditions, and use of health services of Venezuelan migrant women in two main reception cities in Brazil. METHODS: A survey was conducted using respondent-driven sampling (RDS) in the cities of Boa Vista (Roraima), and Manaus (Amazonas). The study included 2012 Venezuelan migrant women aged between 15 and 49 years old who migrated from Venezuela to Brazil between 2018 and 2021. Relative prevalence was calculated, and the χ2 test was used to analyse the homogeneity of proportions. All analyses considered the complex sampling. RESULTS: The main reasons for migrating relate to difficulties obtaining food (54%) and accessing health services (37.8%) in their country of origin. They were young and mixed race (65.7%) and had high school education (69.9%). In Manaus, 3.7% of the interviewees declared that they had no family income in the last month, while in Boa Vista, it was higher (66.2%) (p-value < 0.001). Almost one-third of them sought health care in the last 15 days, and 95% of them received care. The residents of Boa Vista arrived more recently and family income and access to paid work improved with time of residence in Brazil. CONCLUSIONS: Given the increasing flow of Venezuelan migrants crossing to Brazil, a reception system was established for the provision of food, shelter, access to health services, and income transfer programs to migrants. This was the case despite high unemployment and poverty levels and income inequality, particularly in the city of Boa Vista. However, the majority had legal migrant status and had access to the public and universal healthcare system in Brazil (SUS). The use of the SUS was similar in both cities, acting as a buffer for the differences in opportunities offered.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV) infection and sexually transmitted infections (STIs) are major global public health issues. Migrants represent a vulnerable group that faces multiple barriers to access to healthcare services, including HIV/STI testing. This study aimed to assess the factors associated with access to HIV/STI testing in male and female Venezuelan migrants in Peru. METHODS: This was a cross-sectional study involving secondary data analysis of the 2022 Venezuelan Population Residing in Peru Survey. The study was conducted in the eight most populated cities inhabited by Venezuelan migrants and refugees. For each city, the sampling design was probabilistic, stratified, and independent. The outcome variable was whether participants had access to HIV or other STI testing during their stay in Peru. Statistical analysis was stratified by sex owing to potential effect modification. Crude and adjusted prevalence ratios were calculated using generalized linear models Poisson family with log link function. Confidence intervals were calculated to 95%. RESULTS: A total of 3,723 male and 3,984 female migrants were included. Access to HIV/STI testing among male and female migrants was 19.85% and 25.16%, respectively. Among male migrants, being LGBTI, health insured, and married or cohabiting were associated with increased access to HIV/STI testing. Among females, those aged 18-44 years, those who were married or cohabiting and were health insured, and those residing for more than 1 year in Peru were significantly more likely to have access to HIV/STI testing. Moreover, physical/mental disability and unemployed status were associated with a lower probability of HIV/STI testing in females. CONCLUSIONS: Only two in ten Venezuelan migrants and refugees in Peru were screened for HIV/STI, with fewer males than females. Sex-specific sociodemographic, health-related, and migration-related variables were independently associated with access to HIV/STI testing.

RESUMO

The migration of health workforces tends to be economically based benefiting high-income countries, while draining lower-income countries of workers and skills However, national instability or civil conflict may also have the effect of forcing out health workers. However, few articles focus on the experiences of these types of migrants. Peru has become the second largest Latin American destination for Venezuelan forced displaced migrants, a number of which are health workers. While the exact numbers of these workers is unknown, it is estimated that 4000 and 3000 doctors and about 2500 nurses and health technicians from Venezuela reside in Peru. These workers find entry into the heath system difficult due to bureaucratic and costly registration and qualification validation procedures. However, during Covid-19 these conditions were relaxed, and a large number of these heath workers entered the heath workforce. These workers were primarily doctors and worked in urban medical facilities, though there was some distribution across the country's departments. This avenue to the health workforce allowed the mobilisation of dormant health skills and lifted workforce density numbers. Nonetheless, it is too early to see if there have been sustainable improvements, and it remains uncertain how these policies have contributed to the country's UHC goals. Peru's experiences raise the issue of how to mobilise dormant displaced health worker migrants.

RESUMO

Documentation of Echinorhinus brucus, (Bonnaterre, 1788) in the western Atlantic primarily relies on chance observations. Georeferenced records in this area remain notably scarce. This study contributes the second Venezuelan and seventh Caribbean Sea specimens, increasing the western Atlantic count to 15 individuals. All specimens gathered here were sexually mature, with a slight dominance of females. Our bramble shark record appears to be driven more by the interplay of its biology and environmental factors than being a deliberate deep-sea fishery activity, which likely occurs in the Southern Caribbean area.

RESUMO

We report a case of Dirofilaria immitis nematode infection in a dog imported from Venezuela that had been living for 2 years in Santiago, Chile, where this parasite had not been reported before. Our findings warrant surveillance for all dogs imported to Chile, given that suitable conditions exist for establishing this parasite.

RESUMO

It is challenging to quantitatively measure the health vulnerability and risk factors of refugees and migrants residing outside of formal settlement settings. For hard-to-reach populations without available sampling frames, researchers have increasingly turned to novel sampling and statistical methods, like respondent-driven sampling (RDS). "Standard" RDS is typically conducted face-to-face at fixed sites. However, during the coronavirus disease 2019 (COVID-19) pandemic, face-to-face survey methods and recruitment approaches posed high potential risk of virus transmission and infection, making remote RDS approaches optimal. In this paper, we explore the feasibility of implementing telephone and Internet RDS strategies to assess challenges faced by Venezuelan refugees and migrants in the city of Bogotá, Colombia's capital, and the department of Norte de Santander, the main Venezuelan-Colombian border crossing site. We describe RDS assumptions, survey design, formative research, and the implementation of both strategies and present diagnostics for determining whether assumptions are met. Phone-based recruitment strategies in both locations and the Internet strategy in Bogotá achieved their calculated sample size; however, the Internet strategy in Norte de Santander did not. Most RDS assumptions were sufficiently met at sites where sample sizes were reached. These surveys provide valuable lessons for implementing innovative remote strategies with which to study hard-to-reach populations such as refugees and migrants.

RESUMO

BACKGROUND: Malaria-endemic areas are not spared from the impact of coronavirus disease 2019 (COVID-19), leading to co-infection scenarios where overlapping symptoms impose serious diagnostic challenges. Current knowledge on Plasmodium spp. and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) co-infection in pregnant women remains limited, especially in Latin America, where Plasmodium vivax infection is highly prevalent. METHODS: This is a case series of five pregnant women with P. vivax and SARS-CoV-2 co-infection hospitalized in two main malaria referral centers of the Capital District and Bolivar state, Venezuela between March 13, 2020 and December 31, 2021. RESULTS: Clinical and laboratory data from five pregnant women with a mean age of 22 years were analyzed; three of them were in the third trimester of pregnancy. Comorbidities included obesity in two cases, hypertension in one, and asthma in one. Three out of five patients had severe to critical COVID-19 disease. Dry cough, fever, chills, and headache were the most frequent symptoms reported. Laboratory analyses showed elevated aspartate/alanine aminotransferase and creatinine levels, thrombocytopenia, and severe anemia as the most relevant abnormalities. The mean period between symptom onset and a positive molecular test for SARS-CoV-2 infection or positive microscopy for Plasmodium spp. was 4.8 ± 2.5 days and 2.8 ± 1.6 days, respectively. The mean hospital stay was 5.4 ± 7 days. Three women recovered and were discharged from the hospital. Two women died, one from cerebral malaria and one from respiratory failure. Three adverse fetal outcomes were registered, two miscarriages and one stillbirth. CONCLUSION: This study documented a predominance of severe/critical COVID-19 disease and a high proportion of adverse maternal-fetal outcomes among pregnant women with malaria and COVID-19 co-infection. More comprehensive prospective cohort studies are warranted to explore the risk factors, management challenges, and clinical outcomes of pregnant women with this co-infection.

RESUMO

BACKGROUND: Viral hepatitis (VH) is a leading contributor to morbidity and mortality worldwide, constituting a public health problem associated with the level of human development. In recent years, Venezuela has experienced a political, social, and economic crisis and has been impacted by natural disasters that have led to the deterioration of sanitary and health infrastructures modifying the determinants of VH. Despite epidemiological studies conducted in specific regions of the country or populations, the national epidemiological behaviour of VH remains unclear. METHODS: This is a time series study involving records of morbidity and mortality by VH in Venezuela reported during the period from 1990 to 2016. The Venezuelan population was taken as the denominator of the morbidity and mortality rates, according to the Venezuelan National Institute of Statistics and the 2016 population projections from the latest census published on the website of the responsible Venezuelan agency. RESULTS: During the study period, 630,502 cases and 4,679 deaths from VH in Venezuela were analysed. Most of the cases (n = 457,278; 72.6%) were classified as unspecific VH (UVH). The deaths were mainly attributed to VHB (n = 1,532; 32.7%), UVH (n = 1,287; 27.5%), and sequelae of VH (n = 977; 20.8%). The mean rates of cases and deaths from VH in the country were 95 ± 40.4 cases per 100,000 inhabitants and 0.7 ± 0.1 deaths per 100,000 inhabitants, respectively, showing a large dispersion that is evident from the calculation of the coefficients of variation. There was document a strong correlation between UVH and VHA cases (0.78, p < 0.01) morbidity rates. VHB mortality rate was very strongly correlated with sequelae of VH (-0.9, p < 0.01). CONCLUSIONS: VH is a major burden of morbidity and mortality in Venezuela with an endemic-epidemic trend and an intermediate prevalence for VHA, VHB, and VHC. Epidemiological information is not published in a timely manner and diagnostic tests are insufficient in primary health services. There is an urgent need to resume epidemiological surveillance of VH and to optimise the classification system for a better understanding of UVH cases and deaths due to sequelae of VHB and VHC.

RESUMO

OBJECTIVE: To evaluate the factors associated with food insecurity (FI) among Venezuelan migrants residing in Peru. Secondarily, to evaluate the psychometric properties of the Food Insecurity Experience Scale (FIES). DESIGN: A cross-sectional study based on secondary data analysis of the 2022 Venezuelan Population Residing in Peru Survey (ENPOVE-2022, from the Spanish acronym) was conducted. FI was measured with the FIES, whose properties were tested using the Rasch model. Multinomial logistic regression was performed to estimate relative prevalence ratios with their corresponding 95 % confidence intervals. SETTING: This survey was conducted in February and March 2022 in the eight cities most populated by Venezuelan migrants and refugees in Peru. PARTICIPANTS: Venezuelan migrants and refugees over the age of 18 years living in Peru. RESULTS: A total of 7727 participants were included. Rasch reliability was adequate (0·73). The prevalence of mild, moderate and severe FI was 36·71 %, 31·14 % and 10·48 %, respectively. Being aged 25-34 and 35-44 years, unemployed, uninsured, having no formal education or secondary, illegal status, living in a dwelling with 2-4 and more than 4 people, presenting one or more than one chronic disease, residing in Peru for 0-6 months and perceived discrimination were associated with a higher probability of moderate FI. Furthermore, having secondary education, being unemployed, uninsured, never married, illegal, residing in Tumbes, presenting one or more than one chronic disease and perceived discrimination were significantly associated with severe FI. CONCLUSION: Four out of ten Venezuelan migrants residing in Peru presented moderate to severe FI. The FIES showed adequate psychometric properties. Differences in the socio-demographic, health and migratory factors associated with FI levels were found. Inter-sectoral and multi-sectoral interventions are needed and should be focused on addressing the determinants of FI.

RESUMO

It is estimated that 6-7 million people worldwide are infected with Trypanosoma cruzi, the parasite that causes Chagas disease. In Venezuela, Chagas disease remains a public health problem. In this work, T. cruzi isolates from six species of triatomines and mammals of the orders Didelphimorphia and Xenarthra, captured in rural communities of Monagas, underwent parasitological and molecular characterization. A total of 471 triatomines and 17 mammals were captured, with a natural infection rate of 41.4% and 70.6%, respectively. In the male NMRI mouse model used for parasitological characterization (prepatent period, parasitemia curve, mouse mortality, and tissular parasitism), T. cruzi isolates exhibited high lethality due to their pronounced virulence, irrespective of the parasite load in each mouse, resulting in a mortality rate of 75%. Among the vector isolates, in the mouse model, only 2 out of 6 remained alive, while the rest perished during the evaluation. Conversely, the isolates from mammals proved fatal for all the inoculated mice. All isolates were identified as belonging to DTU TcI, based on the molecular markers such as the intergenic region of the miniexon, D7 divergent domain of the 24Sα rDNA, size-variable domain of the 18S rDNA, and hsp60-PCR-RFLP-EcoRV. This study demonstrates the presence of vectors and mammalian reservoirs naturally infected with T. cruzi in communities of Monagas, the 9th largest and 9th most populous state in Venezuela. This situation represents a neglected epidemiological problem demanding urgent attention and imperative health care intervention.

RESUMO

Fusarium wilt of banana (Musa spp.), caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc), is a major constraint to banana production worldwide (Dita et al., 2018). A strain of Foc that affects Cavendish (AAA) bananas in the tropics, called Foc tropical race 4 (TR4; VCG 01213), is of particular concern. Foc TR4 was first detected in Malaysia and Indonesia around 1990 but was restricted to Southeast Asia and northern Australia until 2012. The fungus has since been reported from Africa, the Indian subcontinent, and the Middle East (Viljoen et al., 2020). Foc TR4 was detected in Colombia in 2019 and in Perú in 2021 (Reyes-Herrera et al., 2020). The incursions into Latin America and the Caribbean (LAC) triggered global concerns, as 75% of international export bananas are produced in the region. Banana production in Venezuela, however, is primarily intended for domestic consumption (Aular and Casares, 2011). In 2021 the country produced 533,190 metric tons of banana on an area of 35,896 ha, with an approximate yield of 14,853 kg/ha (FAOSTAT, 2023). In July 2022, severe leaf-yellowing, and wilting, along with internal vascular discoloration of the pseudostem, were noted in Cavendish banana plants cultivar 'Valery' in the states of Aragua (10°11'8″N; 67°34'51″W), Carabobo (10º14'24″N; 67º48'51″W), and Cojedes (9°37'44″N; 68°55'4″W). Necrotic strands from the pseudostems of diseased plants were collected for identification of the causal agent using DNA-based techniques, vegetative compatibility group (VCG) analysis and pathogenicity testing. The samples were first surface disinfected and plated onto potato dextrose agar medium. Single-spored isolates were identified as F. oxysporum based on cultural and morphological characteristics, including white colonies with purple centres, infrequent macroconidia, abundant microconidia on short monophialides, and terminal or intercalary chlamydospores (Leslie and Summerell, 2006). Foc TR4 was identified from five isolates by endpoint and quantitative-PCR using four different primer sets (Li et al. 2013; Dita et al. 2010; Aguayo et al. 2017; Matthews et al. 2020). The same isolates were identified as VCG 01213 by successfully pairing nitrate non-utilizing (nit-1) mutants of the unknown strains with Nit-M testers of Foc TR4 available at Stellenbosch University (Leslie and Summerell, 2006). For pathogenicity testing, 3-month-old Cavendish banana plants cultivar 'Williams' were inoculated with isolates from Venezuela grown on sterile millet seed (Viljoen et al., 2017). Plants developed typical Fusarium wilt symptoms 60 days after inoculation, including yellowing of leaves that progressed from the older to the younger leaves, wilting, and internal discoloration of the pseudostem. Koch's postulates were fulfilled by reisolating and identifying Foc TR4 from the plants by qPCR (Matthews et al., 2020). These results provide scientific proof of the presence of Foc TR4 in Venezuela. The Venezuelan Plant Protection Organization (INSAI) has declared Foc TR4 as a newly introduced pest (January 19, 2023), and infested banana fields were placed under quarantine. Comprehensive surveys are now conducted in all production areas in Venezuela to assess the presence and impact of Foc TR4, and information campaigns were started to make farmers aware of biosecurity protocols. Collaborative initiatives and coordinated actions among all stakeholders are needed to prevent the spread of Foc TR4 to other countries in Latin America, and to develop Foc TR4-resistant bananas (Figueiredo et al. 2023).

RESUMO

Objective: To describe the factors that determine condom use in Venezuelan immigrant sex workers in Colombia. Methods: A qualitative study was conducted with an interpretive hermeneutic approach, using semi-structured interviews developed in the Metropolitan Area of Aburrá Valley, Bogotá, and the Colombian coffee-growing region. Results: Fifty-five interviews were conducted. Of the total number of people interviewed, 60% were cisgender men, 31% were cisgender women, and 9% were transgender women. The average age of the participants was 27 years. Sixty-nine percent were irregular migrants in Colombia. Only 11% were affiliated with the health system. It was observed that condom use is inconsistent among sex workers, depending on personal and social factors. Conclusions: The factors that influence condom use in sex workers of Venezuelan origin in Colombia are determined by various factors, both personal and social. Personal factors relate to knowledge, support networks, and risk perception, while social factors are associated with substance use, stigma and discrimination, and the places where sex work is done. Social factors are the ones that most influence inconsistent condom use in cisgender men and transgender women.

Resultados: Foram realizadas 55 entrevistas. Do total de pessoas entrevistadas, 60% eram homens cisgêneros, 31% mulheres cisgêneros e 9% mulheres transgêneros. A idade média dos participantes foi de 27 anos. Sessenta e nove por cento estão na Colômbia de forma irregular. Em relação à filiação ao sistema de saúde, apenas 11% são filiados. Observou-se que o uso de preservativo em profissionais do sexo é inconsistente, já que depende de fatores pessoais e sociais. Conclusões: Os fatores que influenciam o uso de preservativo por profissionais do sexo de origem venezuelana na Colômbia são determinados por vários aspectos pessoais e sociais. Os aspectos pessoais se referem ao conhecimento, redes de apoio e percepção de risco, enquanto os sociais estão associados ao uso de substâncias psicoativas, ao estigma e à discriminação, e aos locais onde o trabalho sexual é realizado. Esses últimos são os que mais influenciam o uso inconsistente de preservativo por homens cisgêneros e mulheres transgêneros.

RESUMO

Objective: This study seeks to understand the needs associated with the sexual and reproductive health of migrants of Venezuelan origin settled temporarily or permanently in Santiago de Cali, Colombia. Methods: A qualitative study was conducted with Venezuelan migrants between 15 and 60 years old. Participants were selected using the snowball technique. Information was initially gathered from people identified by migrant organizations, followed by information gathering in areas with high concentrations of migrants of Venezuelan origin. In-depth interviews were held, and thematic content was analyzed. Results: Of the 48 migrants who participated, 70.8% did not have legal migratory status and were living in conditions of socioeconomic vulnerability. The participants had scarce economic resources, a lack of job opportunities, precarious human capital, and varying levels of social capital, coupled with weak social integration that limited their awareness and appropriation of their rights. Immigration status constituted an access barrier to health services and other social services. There was a particular need for information on sexual and reproductive health rights, with increased risk among young people 15 to 29 years old and members of the LGBTIQ+ community, due to their greater vulnerability and exposure to unsafe spaces for self-care, personal hygiene, and privacy, in addition to their greater need for health care, treatment of sexually transmitted infections, psychosocial support for violence, substance abuse, family conflicts, and gender transition processes. Conclusions: The sexual and reproductive health needs of Venezuelan migrants are determined by their living conditions and migratory experiences.


Objetivo: Compreender as necessidades associadas à saúde sexual e reprodutiva (SSR) dos migrantes de origem venezuelana estabelecidos temporária ou permanentemente em Santiago de Cali, Colômbia. Método: Foi realizado um estudo qualitativo com migrantes de origem venezuelana entre 15 e 60 anos. Os participantes foram selecionados pela técnica de bola de neve. A coleta de informações começou com pessoas encaminhadas por organizações de migrantes e, posteriormente, percorrendo áreas com alta concentração de migrantes de origem venezuelana. Foram realizadas entrevistas em profundidade e análise de conteúdo temático. Resultados: Participaram 48 migrantes, dos quais 70,8% não tinham sua situação imigratória regularizada e se encontravam em situação de vulnerabilidade socioeconômica. Os participantes tinham poucos recursos econômicos, falta de oportunidades de trabalho, capital humano precário e níveis variáveis de capital social, somados a uma fraca integração social que limitava a efetivação dos direitos dos quais são titulares. O status migratório é uma barreira ao acesso aos serviços de saúde e outros serviços sociais. Destacam-se as necessidades de informação sobre direitos à saúde sexual e reprodutiva, maior risco entre jovens de 15 a 29 anos e na comunidade LGBTIQ+ ­ devido à maior vulnerabilidade e exposição a espaços inseguros para autocuidado, higiene pessoal e privacidade ­, necessidade de cuidados e tratamento de infecções sexualmente transmissíveis, apoio psicossocial em casos de violência, consumo de substâncias psicoativas, conflitos familiares e processos de transição de gênero. Conclusões: As necessidades em matéria de saúde sexual e reprodutiva dos migrantes de origem venezuelana são determinadas por suas condições de vida e trajetórias migratórias.

RESUMO

Objectives: To describe the perspectives of health practitioners on the barriers, gaps, and opportunities that Venezuelan migrant women experienced to accessing sexual and reproductive health (SRH) services during the COVID-19 pandemic and how SRH services were affected in Quito, Ecuador. Methods: Health practitioners involved in SRH services at nine public health care facilities in three zones of Quito were surveyed. The Minimum Initial Service Package readiness assessment tool survey, available from the Inter-Agency Working Group on Reproductive Health in Crisis, was adapted for use and data collection in Ecuador. Results: Of 297 respondents, 227 were included in the analysis. Only 16% of the health practitioners agreed that discrimination against migrant Venezuelans women occurred in the health care system. Of those, only 2.3% described specific conditions associated with discrimination, including requiring identification documents (7.5%) and lack of empathy or responsiveness (6.6%). Most (65.2%) respondents reported that the COVID-19 pandemic affected the use of SRH services by women in the general population and by Venezuelan migrant women more so (56.3%) because of more limited access to SRH services, poverty, and vulnerability. There were no differences between perceptions by levels of health care facility, except with regard to the lack of supplies, awareness of discrimination, and the belief that Venezuelan migrant women were affected more negatively than the local population. Conclusion: The perception among health practitioners in Quito was that discrimination occurred infrequently during the COVID-19 pandemic despite affecting the health care system. However, some level of discrimination toward migrant Venezuelan migrant women seeking SRH services was acknowledged and may be underrepresented.

RESUMO

Objective: To identify sexual risk behaviors and barriers to sexual and reproductive health care (SRH) among Venezuelan female sex workers living in the Dominican Republic. Methods: This was a mixed-methods study using four focus group discussions (FGDs) and a cross-sectional quantitative survey with Venezuelan migrant female sex workers. The study was conducted from September through October 2021 in two urban areas (Santo Domingo and Puerto Plata) in the Dominican Republic. Information collected from the FGDs was analyzed using thematic content analysis, and quantitative data were analyzed using univariate descriptive statistics. Data analysis was conducted from 30 November 2021 to 20 February 2022. Results: In all, 40 Venezuelan migrant female sex workers with a median (range) age of 33 (19-49) years participated in the FGDs and survey. The FDGs identified barriers to SRH services, including immigration status and its implications for formal employment and health access, mental wellbeing, quality-of-life in the Dominican Republic, navigating sex work, perceptions of sex work, SRH knowledge, and limited social support. Findings of the quantitative analysis indicated that most participants reported feeling depressed (78%), lonely/isolated (75%), and having difficulty sleeping (88%). Participants reported an average of 10 sexual partners in the past 30 days; 55% had engaged in sexual practices while under the influence of alcohol; and only 39% had used a condom when performing oral sex in the past 30 days. Regarding AIDS/HIV, 79% had taken an HIV test in the past 6 months, and 74% knew where to seek HIV services. Conclusions: This mixed-methods study found that nationality and social exclusion have a multilayered influence on migrant female sex workers, sexual risk behaviors, and access to health care. Recommendations for effective evidence-based interventions to address sexual health knowledge need to be implemented to address risky sexual behaviors, improve access to SRH, and reduce affordability barriers.

RESUMO

An iterative analysis of Imparfinis, combining phylogenetic analysis based on cytochrome oxidase gene and multivariate morphometrics, revealed a new cryptic species from the Andean tributaries of the Orinoco River basin, which is described here. The new species is sister to a clade constituted by Imparfinis hasemani and Imparfinis pijpersi, both from the river basins of the Guiana Shield, being also the most geographically proximate species. Nonetheless, the new species is most similar in general appearance to Imparfinis guttatus from the Madeira and Paraguay River drainages, being almost undistinguishable by conventional characters of external morphology, differing only by morphometric attributes overall. The new species can be distinguished from the remaining congeners by a unique combination of characters, including lower lobe of caudal fin darker than upper lobe, maxillary barbel reaching or surpassing pelvic-fin insertion, 12-15 gill rakers on first gill arch, 40-42 total vertebrae and 9-10 ribs. The new species constitutes the only representative from the Orinoco River basin belonging to Imparfinis sensu stricto.

RESUMO

For the past 10 years, Venezuela has undergone a severe electric crisis. However, not all regions have been equally affected. The city of Maracaibo has endured more blackouts than other cities, and they have now become routine. This article sought to study the impact of electric shortages on the mental health of Maracaibo's inhabitants. Using a sample from all districts in the city, the study sought to test if there are correlations between the number of hours without electricity (per week), and four dimensions of mental health: anxiety, depression, poor sleep quality, and boredom. Results came out showing that there are moderate correlations across all four variables.
