The probability of having multiple chronic conditions simultaneously, or multimorbidity, tends to increase with age. Immigrants face a particularly high risk of unhealthy ageing. This study investigates the immigrant-native disparities in the speed of age-related chronic disease accumulation, focusing on the number of chronic health conditions; and considers the heterogeneity of this trajectory within immigrant populations by origin and receiving country. We use data from the Survey of Health, Ageing and Retirement in Europe from 2004 to 2020 on adults aged 50 to 79 from 28 European countries and employ both cross-sectional and longitudinal analyses. For longitudinal panel analyses, we use fixed-effects regression models to account for the unobserved heterogeneity related to individual characteristics including migration background. Our results indicate that immigrants report a higher number of chronic conditions at all ages relative to their native-born peers, but also that the immigrant-native differential in the number of chronic conditions decreases from age 65 onwards. When considering differences by origin country, we find that the speed of chronic disease accumulation is slower among immigrants from the Americas and the Asia and Oceania country groups than it is among natives. When looking at differences by receiving country group, we observe that the speed of accumulating chronic diseases is slower among immigrants in Eastern Europe than among natives, particularly at older ages. Our findings suggest that age-related trajectories of health vary substantially among immigrant populations by origin and destination country, which underscore that individual migration histories play a persistent role in shaping the health of ageing immigrant populations throughout the life course.

Background: Patients at risk of breast cancer are submitted to mammography, resulting in a classification of the lesions following the Breast Imaging Reporting and Data System (BI-RADS®). Due to BI-RADS 3 classification problems and the great uncertainty of the possible evolution of this kind of tumours, the integration of mammographic imaging with other techniques and markers of pathology, as metabolic information, may be advisable. Design and Methods: Our study aims to evaluate the possibility to quantify by gas chromatography-mass spectrometry (GC-MS) specific metabolites in the plasma of patients with mammograms classified from BI-RADS 3 to BI-RADS 5, to find similarities or differences in their metabolome. Samples from BI-RADS 3 to 5 patients were compared with samples from a healthy control group. This pilot project aimed at establishing the sensitivity of the metabolomic classification of blood samples of patients undergoing breast radiological analysis and to support a better classification of mammographic cases. Results: Metabolomic analysis revealed a panel of metabolites more abundant in healthy controls, as 3-aminoisobutyric acid, cholesterol, cysteine, stearic, linoleic and palmitic fatty acids. The comparison between samples from BI-RADS 3 and BI-RADS 5 patients, revealed the importance of 4-hydroxyproline, found in higher amount in BI-RADS 3 subjects. Conclusion: Although the low sample number did not allow the attainment of high validated statistical models, some interesting data were obtained, revealing the potential of metabolomics for an improvement in the classification of different mammographic lesions.

Background: Cross-national research shows that although immigrants initially have better health than their native-born counterparts, their health deteriorates over time in their destination countries, converging to natives' health (health convergence). Explanations include acculturation to negative health behaviors, exposure to low socioeconomic status, and social exclusion. Objective: This study is the first to examine how material deprivation, a measure of relative disadvantage that includes elements of SES and social exclusion, interacts with duration of stay to affect immigrants' health convergence. Methods: Using data from Italy (2009), we assess the association between duration of stay and three health outcomes, and we estimate interaction effects of duration of stay with material deprivation. Results: We find immigrants' duration of stay is negatively associated with self-rated health, chronic morbidity, and activity limitations. Immigrants' health converges to natives', net of controls. Convergence is most dramatic for self-rated health, but the pattern is also reflected in chronic morbidity and activity limitations. The health of immigrants who live in conditions of material deprivation is more similar to natives' health at shorter durations of stay, compared to their not-deprived counterparts. Contribution: The paper contributes to a better understanding of the role of social exclusion - measured as material deprivation - on the immigrant-native health convergence process. It is the first to assess the interaction of material conditions and duration of stay in a host country.

Suicidal ideation is a process that is intertwined with suicidal behavior. It begins with the formation of an idea about whether it is worth continuing to live, an idea that can evolve and trigger a series of actions ranging from planning to the execution of the suicidal act. This is a descriptive observational study based on numerical measurements with its respective statistical analysis that established the behavioral patterns of the phenomenon studied. The research proposal was approved by the research committee of the Faculty of Medicine and Surgery, URSE; data collection was performed through the instruments: Beck Suicidal Ideation Scale, Beck Depression Inventory, Abbreviated Scale of School Bullying Questionnaire, Drug Dependence Identification Questionnaire, and Family Apgar. The prevalence of suicidal ideation was 5.4%; 19.7% of the medical students have been victims of bullying in any form; 22.2% reported regular use of alcohol, tobacco, drugs, and other addictive substances; in addition, 17.7% had mild family dysfunction, moderate in 9.9% and severe with 15.3%; depression was recorded to a mild degree with 6.4%, followed by moderate in 1.5% of cases. Suicidal ideation among medical students is of concern; these problems must be addressed comprehensively, promoting a supportive environment that promotes the mental health and well-being of medical students.

Abstract Interactions between multiple genes and environmental factors could be related to the pathogenesis of type 1 diabetes (T1D). The Brazilian population results from different historical miscegenation events, resulting in a highly diverse genetic pool. This study aimed to analyze the mtDNA of patients with T1D and to investigate whether there is a relationship between maternal ancestry, self-reported color and the presence of T1D. The mtDNA control region of 204 patients with T1D residing in three geographic regions of Brazil was sequenced following the International Society for Forensic Genetics (ISFG) recommendations. We obtained a frequency of Native American matrilineal origin (43.6%), African origin (38.2%), and European origin (18.1%). For self-declared color, 42.6% of the patients with diabetes reported that they were White, 50.9% were Brown, and 5.4% were Black. Finally, when we compared the self-declaration data with maternal ancestral origin, we found that for the self-declared White group, there was a greater percentage of haplogroups of Native American origin (50.6%); for the self-declared Black group, there was a greater percentage of African haplogroups (90.9%); and for the Brown group, there was a similar percentage of Native American and African haplogroups (42.3% and 45.2%, respectively). The Brazilian population with diabetic has a maternal heritage of more than 80% Native American and African origin, corroborating the country’s colonization history.
