Morphological and molecular characterization of amblyomma scutatum (acari: ixodidae) accidentally introduced in italy
J Parasitol. 2024 Apr 1;110(2):155-158. doi: 10.1645/20-69.ABSTRACTEight ticks were found in Comacchio (FE), Italy parasitizing a young black iguana (Ctenosaura similis) that had been accidentally transported in a commercial plant container from Costa Rica. Specimens were identified morphologically as Amblyomma scutatum and then confirmed by the barcoding of the mitochondrial cytochrome c oxidase subunit 1 gene. Amblyomma scutatum is a common tick known to infest reptiles in Central America, Mexico, and Venezuela, but not in Europe. In Italy, the possibility for this tick to become endemic is unlikely because of the absenc...

Online xenophobia and mental health among Venezuelan migrant youth in Colombia: The interplay with "in-person" discrimination
Am J Orthopsychiatry. 2024 Apr 11. doi: 10.1037/ort0000730. Online ahead of print.ABSTRACTEmerging research provides insights into migration-related cultural stress experiences and mental health among Venezuelan migrants; however, prior studies have not considered the critical distinction between online xenophobia and in-person discrimination. To address this gap, we assess the psychometric properties of an abbreviated version of the Perceived Online Racism Scale (PORS) with Venezuelan migrant youth and examine the interplay between online xenophobia, in-person discrimination, and mental health. Survey data were collected ...

Heart Transplant in an Immigrant in Brazil: A Learning Experience of a Worldwide Ethical, Legal and Cultural Challenge
Introduction: Guaranteeing basic social rights such as access to healthcare to immigrants is an oncoming challenge triggered by the increase in migration flows worldwide. Although more than 1 million immigrants live in Brazil, transplant in this population is underreported. Herein, we describe the successful heart transplant of an immigrant from Venezuela in the South of Brazil. (Source: The Journal of Heart and Lung Transplantation)

Evaluation of bird-adapted self-amplifying mRNA vaccine formulations in chickens
In this study, we engineered two Tembusu virus (TMUV; family Flaviviridae) replicons encoding varying capsid gene lengths and compared these to the benchmark VEEV replicon in vitro. The TMUV replicon system exhibited a robust and prolonged transgene expression compared to the VEEV replicon system in both avian and mammalian cells. Moreover, the TMUV replicon induced a lesser cytopathic effect compared to the VEEV replicon RNA in vitro. DNA-launched versions of the TMUV and VEEV replicons (DREP) were also developed. The replicons successfully expressed the AIV haemagglutinin (HA) glycoproteins and the IBDV capsid protein (p...

Experiences of pregnant Venezuelan migrants/refugees in Brazil, Ecuador and Peru: a qualitative analysis
It is estimated that since 2014, approximately 7.3 million Venezuelan migrants/refugees have left the country. Although both male and female migrants/refugees are vulnerable, female migrants/refugees are more ... (Source: BMC Pregnancy and Childbirth)

The search for the underlying mutations causing VWD in 13 Venezuelan families
Von Willebrand disease (VWD) is the most common inherited bleeding disorder due to quantitative or qualitative deficiencies of von Willebrand factor (VWF). Six main types of VWD have been described [1]. Relative quantitative deficiencies of functionally normal VWF (VWF levels 0.7) correspond to type 1 (OMIM ID #193400) with dominant inheritance, or complete deficiency to severe VWD type 3 (OMIM ID #277480), with recessive inheritance (VWF:Ag (Source: Thrombosis Research)

IJERPH, Vol. 21, Pages 166: Task Sharing and Remote Delivery of Brief Interpersonal Counseling for Venezuelan Migrants and Refugees Living in Peru during the COVID-19 Pandemic: A Mixed-Methods Pilot Study

Refugees and migrants experience an elevated risk for mental health problems and face significant barriers to receiving services. Interpersonal counseling (IPC-3) is a three-session intervention that can be delivered by non-specialists to provide psychological support and facilitate referrals for individuals in need of specialized care. We piloted IPC-3 delivered remotely by eight Venezuelan refugee and migrant women living in Peru. These counselors provided IPC-3 to Venezuelan refugee and migrant clients in Peru (n = 32) who reported psychological distress. Clients completed assessments o...

South ‐to‐South parental migration patterns and excess weight among children: Insights from a national cross‐sectional study in Colombia
ConclusionColombian children with return migrant parents from Venezuela experienced less excess weight than children with non-migrant parents, but higher rates of food insecurity in migrant households might partially explain this difference. This study calls attention to two serious public health concerns for Colombian children —those who have excess weight and those who lack sufficient food, particularly among migrant returnees (a situation that may have worsened since the COVID-19 pandemic).
