Project description:Pentastomiasis is an emerging snake-borne parasitic zoonosis in the tropics. We describe a molecular and morphological study to diagnose a cluster of asymptomatic abdominal human infections caused by Armillifer grandis. The findings may indicate a silent epidemic in a rural area where severe symptomatic ocular cases with the same parasite species have recently surfaced. Molecular diagnostics are of increasing importance when patient material from remote areas cannot be thoroughly examined locally for logistic reasons.

Project description:BackgroundThe healthy immigrant effect is a phrase that has been used for decades to describe better cardiometabolic health in African immigrants than African Americans. The recent global increase in cardiometabolic diseases raises the possibility that immigrant health may be changing. Therefore, a new assessment of cardiometabolic health in African immigrants is warranted.MethodsGlucose tolerance status, blood pressure, and visceral adipose tissue (VAT) volume were compared in 214 self-identified healthy men comprised of 138 African immigrants, 76 African Americans, mean age 36±9 years [mean±standard deviation (SD); range 20-64 years]. Insulin resistance was defined by the lowest quartile of the insulin sensitivity index (SI≤2.28 mU/L(-1)·min(-1)). The waist circumference (WC) which predicts insulin resistance was determined using receiver operating characteristic curves and the Youden index.ResultsBody mass index (BMI) and WC were lower in African immigrants than African Americans (BMI, 27.4±3.8 vs. 29.3±5.5 kg/m(2), P<0.01; WC, 91±11 vs. 97±16 cm, P<0.01). However, blood pressure, fasting glucose, and 2-hr glucose were higher in the African immigrants (all P<0.01). In addition, African immigrants had a higher prevalence of previously undiagnosed diabetes (8% vs. 0%, P<0.01) and prediabetes (35% vs. 22%, P<0.01). After adjusting for WC, African immigrants had more visceral adipose tissue (VAT) than African Americans (P<0.01). Consequently, the WC that predicted insulin resistance was 92 cm in African immigrants but 102 cm in African Americans.ConclusionAfrican immigrants were less obese than African Americans but had worse cardiometabolic health, specifically higher glucose levels, more hypertension, and greater visceral adiposity. Overall, the healthy immigrant effect may no longer be valid.

Project description:Visceral pentastomiasis in humans is caused by the larval stages (nymphs) of the arthropod-related tongue worms Linguatula serrata, Armillifer armillatus, A. moniliformis, A. grandis, and Porocephalus crotali. The majority of cases has been reported from Africa, Malaysia, and the Middle East, where visceral pentastomiasis may be an incidental finding in autopsies, and less often from China and Latin America. In Europe and North America, the disease is only rarely encountered in immigrants and long-term travelers, and the parasitic lesions may be confused with malignancies, leading to a delay in the correct diagnosis. Since clinical symptoms are variable and serological tests are not readily available, the diagnosis often relies on histopathological examinations. This laboratory symposium focuses on the diagnosis of this unusual parasitic disease and presents its risk factors and epidemiology.

Project description:Prostate cancer (PCa) is the second leading cause of cancer-related death among Black men who present with higher incidence, mortality, and survival compared to other racial groups. African immigrant men, however, are underrepresented in PCa research and thus this research sought to address that gap. This study applied a social determinants of health framework to understand the knowledge, perceptions, and behavioral tendencies regarding PCa in African immigrants. African immigrant men and women residing in different parts of the country (California, Texas, Colorado, Oklahoma, and Florida) from various faith-based organizations, African community groups, and social groups were recruited to participate in key informant interviews (n = 10) and two focus groups (n = 23). Four themes were identified in this study: (a) PCa knowledge and attitudes-while knowledge is very limited, perceptions about prostate health are very strong; (b) culture and gender identity strongly influence African health beliefs; (c) preservation of manhood; and (d) psychosocial stressors (e.g., financial, racial, immigration, lack of community, and negative perceptions of invasiveness of screening) are factors that play a major role in the overall health of African immigrant men. The results of this qualitative study unveiled perceptions, attitudes, beliefs, and knowledge of PCa among African immigrants that should inform the planning, development, and implementation of preventive programs to promote men's health and PCa awareness.

Project description:While recent literature in Germany has compared predictors of welfare use between EU and non-EU immigrants, refugees have yet to be added to the analysis. Using survey data of approximately 4,000 immigrants living in Germany, I examine the determinants of basic unemployment benefits receipt for intra-EU immigrants, refugees, and third country immigrants. In particular, I investigate how education affects the likelihood of welfare use for each immigrant group. Even after controlling for human capital factors, sociodemographic characteristics, and factors related to migration such as legal status and age at migration, refugees remain significantly more likely to receive benefits. Results demonstrate that higher education significantly decreases the likelihood of welfare receipt for EU and third country immigrants, but much less so for refugees. These findings may indicate that refugees' education is not being used to its full potential in the labor market or that they face additional challenges hindering their labor market integration. A further and unanticipated finding is that immigrants who hold permanent residency or German citizenship are less likely to receive unemployment benefits, pointing either to positive effects of a secure residency or selection into permanent residency and citizenship among those with the greatest labor market success. Overall, this research shows that challenges beyond human capital deficiencies and sociodemographic characteristics must be considered when studying immigrants' receipt of social benefits, that not all educational credentials are valued equally, and that the experiences of refugees differ in significant ways from those of other immigrant groups.

Project description:Objective:Immigrants, especially refugees, face unique barriers to accessing health care relative to native born Americans. In this study, we examined how immigration status, health, barriers to access, and knowledge of the health care system relate to the likelihood of having a regular health care provider. Methods:Using logistic regression and data from a community-based participatory study, we estimated the relative likelihood that an African immigrant woman would have a regular health care provider compared with an African American woman. Results:Immigrant status remains a powerful predictor of whether a woman had a regular health care provider after controlling for covariates. African immigrants were 73% less likely to have a regular health care provider than were otherwise similar African American women. Conclusion:Expanding health care educational efforts for immigrants may be warranted. Future research should examine how cultural beliefs and time in residence influence health care utilization among US immigrants.

Project description:Ocular pentastomiasis is a rare infection caused by the larval stage of pentastomids, an unusual group of crustacean-related parasites. Zoonotic pentastomids have a distinct geographical distribution and utilize reptiles or canids as final hosts. Recently, an increasing number of human abdominal infections have been reported in Africa, where pentastomiasis is an emerging, though severely neglected, tropical disease. Here we describe four ocular infections caused by pentastomids from the Democratic Republic of the Congo. Two cases underwent surgery and an Armillifer grandis infection was detected by morphological and molecular approaches. Thus far, 15 other cases of ocular pentastomiasis have been reported worldwide. Twelve cases were caused by Armillifer sp., recorded almost exclusively in Africa, where such infections occur as a consequence of hunting and consuming snakes, their final hosts. Seven further cases were caused by Linguatula serrata, a cosmopolitan pentastomid whose final hosts are usually canids. Intraocular infections caused permanent visual damage in 69% and a total loss of vision in 31% of reported cases. In contrast, ocular adnexal cases had a benign clinical course. Further research is required to estimate the burden, therapeutic options and pathogenesis of this neglected disease.

Project description:IntroductionThe maternal health experiences of African immigrant women, their utilization of health care services, and the effects on maternal health have received limited attention in research. This research explored the maternal health experiences of African immigrant women residing in Clarkston, Georgia, and their use of health services.MethodsFourteen African immigrant women responded to semistructured interviews. An adapted version of the Andersen health care utilization model explained the predisposing factors, enabling factors, and need factors, which influence the use of maternal health care for African immigrant women.ResultsFindings were presented according to the Andersen health care utilization model. Analysis of the interviews resulted in 11 themes. The themes were as follows: (1) Community social structure, (2) community health beliefs, (3) health organization concerning the use of women, infants, and children, (4) social support at the individual level, (5) limited English proficiency, (6) need for better health education, (7) perception of care, (8) health financing, (9) long wait times and lack of transportation, (10) fear of medication and obstetrical interventions, and (11) impact of Female Genital Mutilation/Cutting.DiscussionMaternal health practices of African immigrant women are impacted by environmental and cultural factors. Public health interventions should be implemented to advance African immigrant women's health care utilization practices through required health education and tailored care, which will translate to positive maternal health experiences.

Project description:Migration is a growing phenomenon around the world, including within the African continent. Many migrants, especially African children, face challenges related to health and social inclusion and can face increased health risks. A systematic scoping review of available literature on the health of African migrant children across the globe was conducted to offer insight into these health risks. The review was conducted over a 15-month period from January 2019 to April 2020, yielding 6602 articles once duplicates were removed. This search included electronic databases, reference lists of articles reviewed, and searches of libraries of relevant organisations. A total of 187 studies met the inclusion criteria, of which 159 were quantitative, 22 were qualitative, and 6 used mixed methods. The findings reveal decreased health in this population in areas of nutrition, infectious diseases, mental health, birth outcomes, sexual and reproductive health, physical and developmental health, parasitic infections, oral health, respiratory health, preventative health, endocrine disorders, health care services, and haematological conditions. The findings offer insights into factors influencing the health of African immigrant and refugee children. Further studies, especially qualitative studies, are needed to determine barriers to service access after migration and to investigate other underexplored and overlooked health concerns of African migrant children, including pneumonia and child maltreatment.

Project description:Snakeborne Armillifer pentastomiasis is an emerging human parasitic infection in rural tropical areas where snake meat is eaten. After a series of severe ocular A. grandis larval infections and anecdotal abdominal infection in Sankuru District, Democratic Republic of the Congo, during 2014-2015, we systematically investigated possible pentastomid etiology in patients who underwent surgery in the region. Histologic and molecular analyses by established pentastomid 18S rDNA- and newly developed Armillifer-specific cytochrome oxidase PCRs revealed larval pentastomid lesions in 3.7% of patients. Some persons had A. armillatus and A. grandis co-infections. Another pentastomid larva, Raillietiella sp., was molecularly detected in 1 patient who had concomitant A. grandis and A. armillatus infection. The PCRs used were suitable for detecting pentastomid species even in highly necrotic tissues. Phylogenetic analyses of Armillifer cytochrome oxidase genes detected multiple local strains.
