RESUMO
A total of 381 specimens of the tilapia Oreochromis mossambicus collected monthly from May 2017 to May 2018 in the Laguna de Los Patos, Cumaná, Venezuela, to evaluate reproductive parameters of this non-native species. Significant differences were found in relation to average height and weight between males and females, with the highest values in males. The sex ratio was 1:1.5 (males:females), which deviates significantly from the expected 1:1 ratio. The mean length of sexual maturity (Lm50) was 18.0 cm in females and 20.1 cm in males, reflecting that females mature at smaller sizes than males. The monthly variations of the gonadosomatic index (GSI) and the stages of sexual maturity show two reproductive peaks during the study, in October 2017 and April 2018, coinciding with the rainy and dry seasons in the region respectively. The condition factor (CF) showed significant differences between months, but not between sexes, with an average of 1.87 in females and 1.84 in males. The average absolute fecundity was 921 ± 604.6 eggs per fish, with a relative fecundity of 8.36 ± 3.09 eggs per gram of fish. Differences in oocyte size in mature females confirm that the species can spawn repeatedly over a period, which is considered an important factor for the establishment of tilapia in non-native environments.

Cardiac amyloidosis (CA) is an infiltrative disease characterized by the deposition of misfolded proteins in cardiac interstitial tissue. Interest towards studying this pathology has been growing in the last decade, as new epidemiological insights have revealed that it is not as uncommon as previously believed. Likewise, advances in non-invasive diagnostic approaches and the identification of molecules that modify its long-term progression, even in terms of mortality, have also bolstered interest in CA. Despite this global panorama, in Venezuela, limitations remain regarding the diagnosis of CA, partly associated with a lack of knowledge of the disease. Therefore, additional efforts are necessary for clinical cardiologists to hone their diagnostic skills regarding this disease, as opportune identification is an essential step for its effective management.

[ABSTRACT]. Objective. To evaluate the implementation of HEARTS strategies in a community in the Bolivarian Republic of Venezuela. Methods. Quasi-experimental study evaluating the cascade of care, driving factors, and maturity and performance indicators four months after implementation of the HEARTS initiative in 52 patients with high blood pressure (BP) in the community of La Marroquina. The data were processed using SPSS® Statistics, version 25.0. Student's t-distribution and chi-square tests were applied to determine statistical significance. Results. Fifty patients, 63.5% of them with a low educational level and low or very low socioeconomic status, completed the four-month monitoring period. At baseline, 11.5% had controlled BP and 40.4% initiated monotherapy. By the fourth month, 100% of patients with high BP had been diagnosed, 92% had received treatment, and 52% had achieved control of their BP. Seventy-two percent were receiving combined therapy. Seventy percent of the hypertensive individuals maintained blood pressure levels <140/90 mmHg. The maturity index score was 4 of 5, and the performance index was classified as incipient. Conclusion. This work shows that, in a short time, a good maturity index was achieved through the implementation, by medical and supervised non-medical personnel, of a standardized protocol for diagnosis, treatment, and monitoring of high blood pressure in a rural population. Rates of diagnosis, treatment, and BP control improved, with incipient performance results. Sustaining this initiative will have a major impact on the health of this population. Its implementation as a national public health policy is recommended.

Leptospirosis is a common but underdiagnosed zoonosis. We conducted a 1-year prospective study in La Guaira State, Venezuela, analyzing 71 hospitalized patients who had possible leptospirosis and sampling local rodents and dairy cows. Leptospira rrs gene PCR test results were positive in blood or urine samples from 37/71 patients. Leptospira spp. were isolated from cultured blood or urine samples of 36/71 patients; 29 had L. interrogans, 3 L. noguchii, and 4 L. venezuelensis. Conjunctival suffusion was the most distinguishing clinical sign, many patients had liver involvement, and 8/30 patients with L. interrogans infections died. The Leptospira spp. found in humans were also isolated from local rodents; L. interrogans and L. venezuelensis were isolated from cows on a nearby, rodent-infested farm. Phylogenetic clustering of L. venezuelensis isolates suggested a recently expanded outbreak strain spread by rodents. Increased awareness of leptospirosis prevalence and rapid diagnostic tests are needed to improve patient outcomes.

The present paper comprises a systematic survey of helminths (trematodes, an acanthocephalan and nematodes) found in nine species of freshwater fishes in Ecuador collected in March 1999 and those (a trematode and acanthocephalans) collected from an amphibian and two species of freshwater fishes in Venezuela in 1992, 1996 and 2001. The following 17 helminth species were recorded: Trematoda: Prosthenhystera ornamentosa sp. n., P. obesa (Diesing, 1850), Crassicutis intermedius (Szidat, 1954), C. cichlasomae Manter, 1936 and Glypthelmins eleutherodactyli sp. n. Acanthocephala: Quadrigyrus torquatus Van Cleave, 1920, Gracilisentis variabilis (Diesing, 1851) and Neoechinorhynchus (Neoechinorhynchus) ecuadoris sp. n. Nematoda: Cosmoxynema vianai Travassos, 1949, Travnema travnema Pereira, 1938, Touzeta ecuadoris Petter, 1987, Sprentascaris hypostomi Petter et Cassone, 1984, Sprentascaris sp., Contracaecum sp. Type 1 larvae, Contracaecum sp. Type 2 larvae, Procamallanus (Procamallanus) peraccuratus Pinto, Noronha et Rolas, 1976 and Procamallanus (Spirocamallanus) sp. juv. Nearly all of these parasites are reported from Ecuador or Venezuela for the first time and many of these findings represent new host records. The new species P. ornamentosa sp. n. was collected from the gall-bladder of an unidentified anostomid (Anostomidae, Characiformes) in Ecuador, G. eleutherodactyli sp. n. from the digestive tract of the frog Eleutherodactylus sp. (Eleutherodactylidae, Anura) in Venezuela and N. (N.) ecuadoris sp. n. from the intestine of Lebiasina sp. (Lebiasinidae, Characiformes) in Ecuador. Most parasites are briefly described and illustrated and problems concerning their morphology, taxonomy, hosts and geographical distribution are discussed.

Objetivo: Analizar las barreras de acceso a la atención de la salud según la nacionalidad peruana venezolana, en puérperas de un Hospital Público del Perú, 2022 - 2023. Métodos: Estudio observacional, analítico, prospectivo y transversal; incluyó una muestra de 284 puérperas de nacionalidad peruana y venezolana, del Hospital San Juan de Lurigancho, seleccionadas por muestreo estratificado. La técnica de recolección de datos fue una encuesta y el instrumento un cuestionario válido y confiable. La prueba chi cuadrado de Pearson o exacta de Fisher se usó para determinar la diferencia. La asociación se evaluó con la prueba de regresión de Poisson y el sentido de esta mediante la razón de prevalencia cruda y ajustada. Resultados: El 87,3 % de puérperas fueron peruanas y 12,7 % venezolanas. Las barreras de acceso a la atención de salud más frecuentes en peruanas fueron de disponibilidad: el no contar con todos los servicios necesarios para una atención (p < 0,001) y el de aceptabilidad: sentir que sus creencias o costumbres fueron afectadas (p < 0,001). Las puérperas venezolanas reportaron como barreras de aceptabilidad: haber recibido un trato diferente por ser migrante (p < 0,001) y haber sentido discriminación durante la atención (p = 0,007). Conclusión. Existe diferencia significativa en las barreras de acceso a la atención de la salud en puérperas, presentándose barreras de disponibilidad y aceptabilidad en peruanas y la última en venezolanas(AU)
Objective: Analyze the barriers to access to health care according to Peruvian - Venezuelan nationality in postpartum women in a Public Hospital of Peru 2022 2023. Methods: Observational, analytical, prospective and cross-sectional study; included a sample of 284 postpartum women of Peruvian and Venezuelan nationality, from the San Juan de Lurigancho Hospital, selected by stratified sampling. The data collection technique was a survey and the instrument was a valid and reliable questionnaire. Pearson's chi-square or Fisher's exact test was used to determine the difference. The association was assessed using the Poisson regression test and the sense of regression using the crude and adjusted prevalence ratio. Results: 87,3 % of postpartum women were Peruvian and 12,7 % Venezuelan. The most frequent barriers to access to health care in Peruvians were availability: not having all the services necessary for care (p < 0,001) and acceptability: feeling that their beliefs or customs were affected (p < 0,001). Venezuelan postpartum women reported as barriers to acceptability: having received different treatment for being a migrant (p < 0,001) and having felt discrimination during care (p = 0,007). Conclusions: There is a significant difference in the barriers to access to health care in postpartum women, with availability and acceptability barriers occurring in Peruvian women and the latter in Venezuelan women(AU)

In 2021, an RDS survey was conducted among Venezuelan migrant women of reproductive age who migrated to two Brazilian cities (Manaus and Boa Vista) from 2018 to 2021. To start the RDS recruitment, we chose seeds non-randomly in both cities. The study variables were age, educational level, self-rated health, pregnancy, migratory status and use of health services. We estimated the prevalence, confidence intervals and homophily effects by variable category. We used a multivariate logistic regression model to identify the main factors associated with healthcare use. A total of 761 women were recruited in Manaus and 1268 in Boa Vista. Manaus showed more irregular migrants than Boa Vista. The main reasons for using health services were as follows: illness, disease prevention and prenatal care. The logistic regression model showed the use of health services was associated with educational level and healthcare needs but not with migratory status. The social inclusion of Venezuelan migrants is extremely relevant, although many challenges must be overcome. The strategy of the Brazilian Federal Government for providing humanitarian assistance to Venezuelan migrants should be expanded to include and facilitate their integration into labor markets, access to healthcare and education, benefiting both migrants and the Brazilian people by reducing social inequality.

The economic, social, and health crisis in Venezuela has resulted in the largest forced migration in recent Latin American history. The general scenario in host countries influence migrants' self-perception of quality of life, which can be understood as an indicator of their level of integration. The COVID-19 pandemic has exacerbated socioeconomic and health vulnerabilities, especially for forced migrants. We hypothesized that the adverse circumstances faced by Venezuelan migrants during the pandemic have deepened their vulnerability, which may have influenced their perception of quality of life. This study aims to evaluate the quality of life of Venezuelan migrants in Brazil during the COVID-19 pandemic. We assessed the quality of life of 312 adult Venezuelan migrants living in Brazil using the World Health Organization WHOQOL-BREF quality of life assessment, which was self-administered online from October 20, 2020, to May 10, 2021. The associations of quality of life and its domains with participants' characteristics were analyzed via multiple linear regression models. Mean quality of life score was 44.7 (±21.8) on a scale of 0 to 100. The best recorded mean was in the physical domain (66.2±17.8) and the worst in the environmental domain (51.1±14.6). The worst quality of life was associated with being a woman, not living with a partner, lower household income, and discrimination based on nationality. Factors associated with overall quality of life and respective domains, especially income and discrimination, were also observed in other studies as obstacles to Venezuelan migrants. The unsatisfactory quality of life among Venezuelans living in Brazil may have been worsened by the pandemic during the study period.

Self-rated health is an indicator that can be easily identified in health surveys, widely used to measure physical, social, mental, and health aspects of the population, and predict premature mortality. In Venezuela, this information only began to be collected recently, in the National Survey of Living Conditions (ENCOVI). In this context, our study aims to analyze the demographic and socioeconomic factors associated with non-positive self-rated health among Venezuelan adults. The ENCOVI 2021 (n = 16,803) was used as a data source, assessing a probability stratified sample with questions about health, education, emigration, and other social and economic aspects. Crude and adjusted prevalence ratio analyses were performed using Poisson regression models with robust variance. The prevalence of fair/bad self-rated health among Venezuelans was 17.8%. The results indicated a strong association between outcome prevalence and age group, 3.81 times higher (95%CI: 3.29-4.41) among individuals aged 60 or more when compared to individuals aged 18 to 29 years. Also, participants experiencing severe food insecurity had a prevalence 2 times higher (95%CI: 1.61-2.47) than those who did not have any level of food insecurity. Factors such as poverty, education, recent emigration of family members, and sex also showed a significant influence, also when analyzed independently. The results show that special attention should be dedicated to the health of individuals facing hunger and of the older people.

Quartzite caves located on table-top mountains (tepuis) in the Guyana Shield, are ancient, remote, and pristine subterranean environments where microbes have evolved peculiar metabolic strategies to thrive in silica-rich, slightly acidic and oligotrophic conditions. In this study, we explored the culturable fraction of the microbiota inhabiting the (ortho)quartzite cave systems in Venezuelan tepui (remote table-top mountains) and we investigated their metabolic and enzymatic activities in relation with silica solubilization and extracellular hydrolytic activities as well as the capacity to produce antimicrobial compounds. Eighty microbial strains were isolated with a range of different enzymatic capabilities. More than half of the isolated strains performed at least three enzymatic activities and four bacterial strains displayed antimicrobial activities. The antimicrobial producers Paraburkholderia bryophila CMB_CA002 and Sphingomonas sp. MEM_CA187, were further analyzed by conducting chemotaxonomy, phylogenomics, and phenomics. While the isolate MEM_CA187 represents a novel species of the genus Sphingomonas, for which the name Sphingomonas imawarii sp. nov. is proposed, P. bryophila CMB_CA002 is affiliated with a few strains of the same species that are antimicrobial producers. Chemical analyses demonstrated that CMB_CA002 produces ditropolonyl sulfide that has a broad range of activity and a possibly novel siderophore. Although the antimicrobial compounds produced by MEM_CA187 could not be identified through HPLC-MS analysis due to the absence of reference compounds, it represents the first soil-associated Sphingomonas strain with the capacity to produce antimicrobials. This work provides first insights into the metabolic potential present in quartzite cave systems pointing out that these environments are a novel and still understudied source of microbial strains with biotechnological potential.

In the Americas, onchocerciasis has been eliminated in 11 of 13 endemic foci by mass administration of ivermectin. The remaining at-risk population resides in a contiguous cross-border transmission zone located in the Amazon jungle in northwest Brazil and southern Venezuela, known as the Yanomami Focus Area. Here, we describe the development and implementation of a data-driven tool, called the Scorecard Approach (SCA), for the 393 communities that comprise the Venezuela South Focus. The SCA was first applied in 2018 and is reassessed on an annual basis. This operational strategy seeks to prioritize communities with low ivermectin coverage while taking into account the nature and variation of other epidemiological and logistical variables. Numeric scores are assigned for each factor and added together to yield a composite score for each community that is categorized as high, medium, or low priority. In this way, the SCA serves as a valuable and comprehensive strategy for planning, monitoring, and maximizing programmatic efficiency. In addition, it has allowed the country to face the main challenges of this endemic area: its remoteness, its large areas of territory to cover, the semi-nomadic nature of the Yanomami people, and their continuous cross-border movements. For 2022, the SCA categorized 54 (13.7%), 108 (27.5%), and 231 (58.8%) communities as high, medium, and low priority, respectively. The results presented here show that prioritizing communities at risk and with greatest needs increases the feasibility of interrupting the transmission of onchocerciasis by 2025 in the last endemic focus in the Americas.

Colombia hosts the largest number of refugees and migrants fleeing the humanitarian emergency in Venezuela, many of whom experience high levels of displacement-related trauma and adversity. Yet, Colombian mental health services do not meet the needs of this population. Scalable, task-sharing interventions, such as Group Problem Management Plus (Group PM+), have the potential to bridge this gap by utilizing lay workers to provide the intervention. However, the current literature lacks a comprehensive understanding of how and for whom Group PM+ is most effective. This mixed methods study utilized data from a randomized effectiveness-implementation trial to examine the mediators and moderators of Group PM+ on mental health outcomes. One hundred twenty-eight migrant and refugee women in northern Colombia participated in Group PM+ delivered by trained community members. Patterns in moderation effects showed that participants in more stable, less marginalized positions improved the most. Results from linear regression models showed that Group PM+-related skill acquisition was not a significant mediator of the association between session attendance and mental health outcomes. Participants and facilitators reported additional possible mediators and community-level moderators that warrant future research. Further studies are needed to examine mediators and moderators contributing to the effectiveness of task-shared, scalable, psychological interventions in diverse contexts.

OBJECTIVES: A growing body of research points to a relationship between exposure to migration-related cultural stress and mental health problems. However, such research is often conducted with the tacit assumption that postmigration experiences are the primary-if not singular-driver of psychological distress. In the present study, we aim to extend the cultural-stress paradigm by examining the influences of both premigration crisis exposure and postmigration cultural stress on depression in a sample of Venezuelan crisis migrants in Colombia. METHOD: Survey data for the present study were collected from Venezuelan youth (N = 429, ages 12-17, Mage = 14.0 years, 49% female) and adults (N = 566, ages 18+, Mage = 35.1 years, 82% female) in Bogota and Medellin, Colombia between April and June 2023. RESULTS: Both crisis exposure and discrimination were independently related to depressive symptoms. However, when examined in a multivariate model along with discrimination, crisis exposure was not a significant predictor of depressive symptoms among youth, and its influence weakened considerably among adults. Among both youth and adults, a Crisis Exposure × Discrimination interaction term significantly predicted depressive symptoms, indicating that discrimination was a more robust predictor of depressive symptoms among those endorsing lower levels of crisis exposure than among those reporting high levels of crisis exposure. CONCLUSION: Our research provides new insights into the experiences of Venezuelan migrant youth and adults in Colombia. It provides further support for the importance of drawing from a crisis-informed cultural-stress framework when working with crisis migrant populations.

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.

Introduction: The emigration of Venezuelans has seen a significant increase in recent years. The aim of this study was to identify factors associated with access to contraceptives in migrant women from Venezuela residing in Peru. Methods: An exploratory cross-sectional study was conducted using data from the Second Survey of the Venezuelan Population Residing in Peru. Access to contraceptives (yes/no) was established as the dependent variable. A Poisson regression model was performed for complex samples, and crude (PRc) and adjusted (PRa) prevalence ratios were reported. Results: A total of 3617 migrant women were analyzed, with 50.12% reporting access to contraceptives. Factors associated with greater access to contraceptives included being between 20 to 29 years old, having a university education, the entry period after the declaration of COVID-19 quarantine was associated with lower access to contraceptives. Conclusions: Access to contraceptives for Venezuelan migrants should be provided to all, as it is a free service in Peru. Additionally, education and family planning should be provided from the basic or middle school level to prevent unintended pregnancies in the future. Complete coverage should be provided regardless of the time of entry into Peru.

An estimated 7.7 million Venezuelans have fled a severe humanitarian crisis in their country, most (70%) to other middle-income host countries in the same Andean region. Migration-related exposures during periconception and other critical gestational periods can adversely impact maternal-perinatal outcomes. Emerging evidence suggests that Venezuelan refugee and migrant women (VRMW) who migrate to Andean host countries are at-risk for delivering preterm and low birthweight infants and for Cesarean-sections. However, relatively few studies have examined obstetrical complications that could contribute to these or other short- and longer-term health outcomes of VRMW and/or their offspring. Our exploratory study analyzed four recent years of national hospital discharge data (2018-2021) from Ecuador to compare the primary discharge diagnoses of VRMW (n = 29,005) and Ecuadorian nationals (n = 1,136,796) for ICD-10 O code obstetrical complications related to or aggravated by pregnancy, childbirth, or the puerperium. Our findings indicated that VRMW were hospitalized for 0.5 days longer than Ecuadorian reference group women and they had higher adjusted odds (aOR) for a primary discharge diagnosis for obstetrical complications including preeclampsia (aOR:1.62, 95% CI:1.55,1.69), preterm labor (aOR:1.20, 95% CI:1.11,1.31), premature rupture of membranes (aOR: 1.72, 95% CI:1.63,1.83), oligohydraminos (aOR:1.24, 95% CI:1.12,1.36), obstructed labor (aOR: 1.39, 95% CI:1.31,1.47), perineal lacerations/other obstetric trauma (aOR:1.76, 95% CI:1.63, 1.91), STIs (aOR:2.59, 95% CI:1.29,2.92), anemia (aOR:1.33, 95% CI:1.24,1.42), and ectopic pregnancy (aOR:1.16 95% CI:1.04,1.28). They had similar aOR for diagnosed gestational diabetes and spontaneous abortion (SAB) compared to the reference group but a reduced aOR for genitourinary infections (aOR:0.79, 95% CI:0.74,0.84) and early pregnancy hemorrhage not ending in SAB (aOR:0.43, 95% CI:0.36,0.51). Our findings underscore the vulnerability of VRMW for a number of potentially serious obstetrical complications with the potential to adversely impact the short- and longer-term health of mothers and their offspring. Future studies should collect more detailed information on the migration status, experiences, and exposures of MRMW that influence their risk for obstetrical complications. These are needed to expand our findings to better understand why they have excess risk for these and to inform social and public health policies, programs and targeted interventions aimed at reducing the risk of this vulnerable refugee and migrant group.

OBJECTIVE: To characterize and analyze violence committed against Venezuelan immigrant female sex workers, from the perspective of an intersectional look at social class, gender and race-ethnicity. METHOD: Exploratory study with a qualitative approach. Data sources: interviews with 15 Venezuelan immigrant women sex workers and 37 Brazilian online media reports that addressed the topic. Data were submitted to thematic content analysis, with the support of Qualitative Data Analysis (WebQDA) software. RESULTS: Thematic analysis of data from reports and interviews allowed the emergence of three empirical categories: Structural violence and reasons that led to prostitution: a question of social class; Among the forms of violence, the most feared: physical violence; Violence based on gender and race-ethnicity. CONCLUSION: The study made it possible to recognize that Venezuelan immigrant women who are sex workers in Brazil are subject to different types of violence and exploitation. This scenario is due to a reality of life and work that is based on the exploitation of female workers who experience the consequences of the interweaving of subalternities characteristic of their social insertion of class, gender and race-ethnicity.

Infanticide and adoption have been attributed to sexual selection, where an individual later reproduces with the parent whose offspring it killed or adopted. While sexually selected infanticide is well known, evidence for sexually selected adoption is anecdotal. We report on both behaviors at 346 nests over 27 y in green-rumped parrotlets (Forpus passerinus) in Venezuela. Parrotlets are monogamous with long-term pair bonds, exhibit a strongly male-biased adult sex ratio, and nest in cavities that are in short supply, creating intense competition for nest sites and mates. Infanticide attacks occurred at 256 nests in two distinct contexts: 1) Attacks were primarily committed by nonbreeding pairs (69%) attempting to evict parents from the cavity. Infanticide attacks per nest were positively correlated with population size and evicting pairs never adopted abandoned offspring. Competition for limited nest sites was a primary cause of eviction-driven infanticide, and 2) attacks occurred less frequently at nests where one mate died (31%), was perpetrated primarily by stepparents of both sexes, and was independent of population size. Thus, within a single species and mating system, infanticide occurred in multiple contexts due to multiple drivers. Nevertheless, 48% of stepparents of both sexes adopted offspring, and another 23% of stepfathers exhibited both infanticide and long-term care. Stepfathers were often young males who subsequently nested with widows, reaching earlier ages of first breeding than competitors and demonstrating sexually selected adoption. Adoption and infanticide conferred similar fitness benefits to stepfathers and appeared to be equivalent strategies driven by limited breeding opportunities, male-biased sex ratios, and long-term monogamy.
