BACKGROUND Anemia associated with cardiovascular diseases(CVD) is a common condition in older persons. Prevalence and prognostic role of anemia were extensively studied in patients with myocardial infarction(MI) or congestive heart failure(CHF) whereas limited data were available on patients with atrial fibrillation(AF). This study was conducted to assess the clinical prevalence and prognostic relevance of anemia in elderly patients affected by AF and other *** A total of 866 elderly patients(430 men and 436 women, age: 65-98 years, mean age: 85 ± 10 years) were *** these patients, 267 patients had acute non-ST-segment elevation MI(NSTEMI), 176 patients had acute CHF, 194 patients had acute AF and 229 patients were aged-matched healthy persons(CTR). All parameters were measured at the hospital admission and cardiovascular mortality was assessed during twenty-four months of *** The prevalence of anemia was higher in NSTEMI, CHF and AF patients compared to CTR subjects(50% vs. 15%, P <0.05), with normocytic anemia being the most prevalent type(90%). Adjusted mortality risk was higher in anemic patient versus non-anemic patient in all the groups of patients [NSTEMI: hazard ratio(HR) = 1.81, 95% CI: 1.06-2.13;CHF: HR = 2.49, 95% CI:1.31-4.75;AF: HR = 1.98, 95% CI: 1.01-3.88]. Decreased hemoglobin levels(P = 0.001) and high reticulocyte index(P = 0.023) were associated with higher mortality in CVD *** The significant associations between CVD and anemia and the prognostic relevance of anemia for elderly patients with CVD were confirmed in this study. The presence of anemia in AF patients is associated with a two-fold increased mortality risk compared with non-anemic AF patients. Low hemoglobin and high reticulocyte count independently predict mortality in elderly patients with CVD.

Epidemiological Profile of Men Who Have Sex with Men: First Data about Male Sex Workers in Central African Republic (CAR)

引用

Advances in Sexual Medicine 2024年第1期14卷 1-11页

作者： Hermione Dahlia Mossoro-Kpinde Balekouzou Augustin paola Julienne Demba Henri Saint Calvaire Diemer Direction de la Médecine du Travail Ministère du Travail de l’Emploi de la Protection Sociale et de la Formation Professionnelle Ban-gui République Centrafricaine Comité National de Lutte contre le Sida Bangui République Centrafricaine Faculté des Sciences de la Santé Université de Bangui Bangui République Centrafricaine Département de Santé Publique Faculté des Sciences de la Santé Université de Bangui Bangui République Centrafricaine

Objectives: Sex work is not well documented among African men. The aim of this study was to describe the epidemiological profile of men who have sex with men (MSM) and eventually to determine the proportion of sex workers (SW) among them, as well as the proportion of MSM who have been victims of gender-based violence (GBV). Material and Methods: A cross-sectional study coordinated by the Direction de la Médecine du Travail was carried out at the headquarters of the association ALTERNATIVES in Bangui Bangui from July 1 to October 31, 2021. Consenting MSM present during the study period were systematically included. Sociodemographic variables, those relating to the future vision of the activity and to GBV were collected and analyzed using Epi-Info version 7 software. Results: Forty MSM with an average age of 23 years and mainly secondary education (75.0%) were included. The vast majority of MSM were unemployed (85.0%). 45.0% had been victims of GBV and wanted to stop working as an MSM (47.5%), and almost 2/3 (65.0%) would accept another income-generating activity in exchange for the MSM. Violence was sexual (32.5%), economic (22.5%), physical (20.0%), verbal (12.5%) and psychological (12.5%). Conclusion: The MSM were mainly young, poorly educated, unemployed, and almost half were victims of GBV. The desire to change MSM activity to another income-generating activity alongside that of MSM shows that many of them are SW, workers in the informal sector. This must be taken into account in prevention activities, even if the data needs to be confirmed on a much larger sample.
