emigration

HLA studies in Crete show that this population is related to North Africans and also Iberians. This may be a reflection of a common prehistoric first Europeans relationships with North Africans and drying Saharan emigration after 10,000 years BC; it may be specifically represented by a primitive and early cult to the bull in both Cretan (Minoan) and Iberian populations. In the present study, unrelated Cretans representing different Island parts have been studied for class II HLA-DRB1 and -DQB1 alleles...

AbstractIn species with resource-defense mating systems (such as most temperate-breeding songbirds), male dispersal is often considered to be limited in both frequency and spatial extent. When dispersal occurs within a breeding season, the favored explanation is ecological resource tracking. In contrast, movements of male birds associated with temporary emigration, such as polyterritoriality (i.e., defense of an additional location after attracting a female in the initial territory), are usually attributed to mate searching...

Hispanics in the United States (U.S.) have previously exhibited lower guideline-concordant colorectal cancer (CRC) screening uptake than non-Hispanic (NH) Whites, with disparities accentuated in foreign-born Hispanics, however it is unclear whether nativity-related CRC screening disparities have changed in the last two decades and whether these disparities are attenuated after adjusting for socioeconomic and demographic characteristics. We evaluated CRC screening adherence in foreign- and U.S.-born Hispanics compared to U...

The ubiquity and ease with which microbial cells disperse over space is a key concept in microbiology, especially in microbial ecology. The phenomenon prompted Baas Becking's famous "everything is everywhere" statement that now acts as the null hypothesis in studies that test the dispersal limitation of microbial taxa. Despite covering the content in lectures, exam performance indicated that the concepts of dispersal and biogeography challenged undergraduate students in an upper-level Microbial Ecology course...

Covid-19 has challenged health systems around the world and increased the global competition for medical professionals. This article investigates if the pandemic and its management became an important push factor influencing the migration intentions of medical students and junior doctors and how this factor compared in importance to others. A mixed methods study-a survey and in-depth interviews-was conducted with final-year students at public medical universities in Poland, a country already suffering from a significant emigration of medical staff...

Reliable population estimates are important for making informed management decisions about wildlife species. Standardized survey protocols have been developed for monitoring population trends of the wood turtle (Glyptemys insculpta), a semi-aquatic freshwater turtle species of conservation concern throughout its distribution in east-central North America. The protocols use repeated active search surveys of defined areas, allowing for estimation of survey-specific detection probability (p) and site-specific abundance...

BACKGROUND: As a vulnerable group in HIV control programs, immigrants face various obstacles to HIV testing. Despite the effectiveness of peer interventions on health promotion in HIV testing, relatively little is known about how these interventions work. This realist review aims to understand why, how, and under what conditions peer interventions can improve immigrants' HIV testing uptake. METHODS: We followed the steps suggested by Pawson and colleagues for conducting the realist review...

A large body of research has documented racial/ethnic disparities in childhood obesity in the United States (US) but less work has sought to understand differences within racial groups. Longitudinal studies are needed to describe BMI trajectories across development, particularly for Black children from immigrant families who have been underrepresented in childhood obesity research. The current study utilizes BMI data collected longitudinally from ages 5 to 8 years and growth mixture modeling to (1) identify and visualize growth patterns among Black children from primarily Caribbean immigrant families, and (2) to compare these patterns to growth trajectories among Black children from US-born families...

Suicide remains a major public health problem, with nearly 1 million deaths per year. The number tends to increase over time and factors leading to suicide suicidal behaviors are complex. However, there is a paucity of evidence on suicidal behaviors and the associated factors among people living with HIV (PLWH) in Indonesia. Therefore, this study aimed to estimate the prevalence and associated factors of suicidal behavior between indigenous and non-indigenous living with HIV who were on Dolutegravir and Efavirenz therapies...

Foreign-born (FB) persons represent a large proportion of adults with chronic hepatitis B (CHB) in Canada due to higher prevalence rates in countries of birth for FB persons. Suboptimal awareness and low rates of hepatitis delta virus (HDV) testing contribute to underdiagnosis and gaps in accurate estimates of Canada HDV prevalence. We aim to provide an assessment of CHB and HDV prevalence in Canada using a comprehensive literature review and meta-analysis. A comprehensive literature review of articles reporting HBsAg seroprevalence and anti-HDV prevalence was conducted to calculate country-specific rates and pooled prevalence of CHB and HDV using meta-analyses...

AIMS/HYPOTHESIS: Children and adults born preterm have an increased risk of type 1 diabetes. However, there is limited information on risk patterns across the full range of gestational ages, especially after extremely preterm birth (23-27 weeks of gestation). We investigated the risk of type 1 diabetes in childhood and young adulthood across the full range of length of gestation at birth. METHODS: Data were obtained from national registers in Finland, Norway and Sweden...

The period described in this chapter reflects activity prior to the establishment of surgical centers in Europe in the twelfth century. It is a kind of prologue to the reintroduction of high-quality surgical practice. Religious squabbles within Christianity led to European medicine and surgery, the principles of which were written in Greek, being transported eastwards into the region newly dominated by Islam. There the works were translated into Arabic and during three to four hundred years, the works were not only retained but were enriched by contributions from within Arab culture...

People from refugee and asylum seeker backgrounds resettling in Australia often experience intersecting risks for poor mental and physical health. Physical activity can promote better health outcomes, however there are limited programs tailored for this population. Therefore, understanding how to support refugees and asylum seekers to engage in physical activity is crucial. This paper aims to describe how the experience-based co-design (EBCD) process was used to identify priorities for a new physical activity service for refugees and asylum seekers...

To control immune responses, regulatory CD4+ CD25+ Foxp3+ T cells (Treg) maintain their wide and diverse repertoire through continuous arrival of recent thymic emigrants (RTE). However, during puberty, the activity of RTE starts to decline as a natural process of thymic involution, introducing consequences, not completely described, to the repertoire. Type 1 diabetes (T1D) patients show quantitative and qualitative impairments on the Treg cells. Our aim was to evaluate peripheral Treg and RTE cell frequencies, in T1D patients from two distinct age groups (young and adults) and verify if HLA phenotypes are concomitant associated...

How has the COVID-19 pandemic affected public attitudes toward immigration? Long-term evidence in Europe and the United States suggests attitudes to immigration are relatively stable and, in some cases, becoming more favorable with high volatility instead of the perceived importance of the issue. However, theoretically a global pandemic could exacerbate people's fears of outsiders or that migration may contribute to the disease. By contrast, attitudes could remain stable if their distal drivers prove to be robust enough to withstand the shock of COVID-19...

Emerging evidence suggests that the COVID-19 pandemic has extracted a substantial toll on immigrant communities in the United States, due in part to increased potential risk of exposure for immigrants to COVID-19 in the workplace. In this article, we use federal guidance on which industries in the United States were designated essential during the COVID-19 pandemic, information about the ability to work remotely, and data from the 2019 American Community Survey to estimate the distribution of essential frontline workers by nativity and immigrant legal status...

Every government in the world introduced restrictions to human mobility - that is, the movement of persons across and within state borders - in response to the COVID-19 pandemic. Such restrictions thus constituted a global phenomenon, but they were by no means globally uniform; rather, they varied significantly between and within states, as well as over time. This research note presents different data sources for studying the drivers and outcomes of mobility restrictions, highlighting specific ways in which the data can be used...

The nursing shortage is a multi-causal phenomenon that affects all countries and currently a global concern. The shortage of nurses jeopardizes the sustainability of health systems and the population health outcomes. Spain has historically had no difficulties in attracting new generations of nurses. The shortage of nurses is caused by the precarious working conditions and lack of professional development that have led to episodes of high international migration and abandonment of the profession. In this paper we focus on the evolution of different indicators of the working conditions of non-specialist nurses, who make up the bulk of the profession...

Inadequate comprehension of healthcare information contributes to poor health outcomes. Ethnic minorities are one of the populations most affected by low health and oral health literacy (OHL). The hypothesis of the current study was that an oral health education program (OHEP) can improve the OHL, oral health awareness and behaviors of refugees. We also hypothesized that there will be a difference between OHL in English and native language in the Pre-intervention phase. Fifty-two adult refugees participated in an educational program that included a comprehensive and culturally sensitive PowerPoint presentation and hands-on learning activities on oral health topics...

Recognizing the inequities in developmental screening and services for children in immigrant families, a pediatric primary care clinic in partnership with a community-based early childhood program co-created a bicultural, bilingual early childhood developmental (ECD) family navigator program in Seattle, Washington. The primary aim of this study is to explore caregivers' perspectives about this program. Twenty-seven caregivers of young children participated in semi-structured interviews that were thematically analyzed...
