Relating the outcome of HCV infection and different host SNP polymorphisms in a Majorcan population coinfected with HCV–HIV and treated with pegIFN-RBV

Hepatitis C virus (HCV) is one of the major causes of chronic hepatitis, cirrhosis, and hepatocellular carcinoma, and the development of HCV-related disease is accelerated in individuals coinfected with human immunodeficiency-1 virus (HIV). In the present study, we correlated different host single-nucleotide polymorphisms (SNPs) in the IL28B, CTLA4, LDLr, and HFE genes and mitochondrial DNA (mtDNA) haplogroups with the outcome of HCV infection and the response to pegylated-interferon plus ribavirin (pegIFN-RBV) treatment. Our study population consisted of 63 Majorcan patients coinfected with HCV and HIV and 59 anonymous unrelated controls. Whereas the population frequency of IL28B alleles was similar to that found in a North-American cohort of European descent, the frequency of the rs12979860 C allele was lower than that determined in other cohorts from Spain. The frequencies of CTLA4 and LDLr polymorphisms were comparable to those reported in other populations. Significant differences between cases and control cohorts occurred only for the H63D mutation of the HFE gene. There were no other differences in the frequencies of other polymorphisms or mtDNA haplogroups. The IL28B rs12979860 CC genotype was shown to be associated with a rapid virological response, and the spontaneous viral clearance rate for HCV was higher in patients with the CTLA4+49 G allele. There was no relationship between SNPs in the LDLr and HFE genes and mtDNA haplogroups and the response to treatment. Our results suggest that the host genetic background plays a significant role in the pegIFN-RBV response of patients coinfected with HCV and HIV.

Hospitalizações por condições cardiovasculares sensíveis à atenção primária em municípios goianos

OBJETIVO: Analisar taxas de hospitalização por condições cardiovasculares sensíveis à atenção primária. MÉTODOS: Estudo ecológico com 237 municípios do Estado de Goiás, de 2000 a 2008, utilizando dados do Sistema de Informação Hospitalar e Sistema de Informação da Atenção Básica. As taxas de hospitalização foram calculadas pela proporção entre o número de hospitalizações por condições cardiovasculares e a população acima de 40 anos. Foram avaliadas em triênios: A (2000-2002), B (2003-2005) e C (2006-2008), segundo sexo, faixa etária, porte populacional, pertencimento à região metropolitana, macrorregião de saúde, distância da capital, Índice de Condições de Vida e Saúde e cobertura de Estratégia Saúde da Família. A cobertura populacional potencial da Saúde da Família foi calculada conforme diretrizes do Ministério da Saúde. A variabilidade das taxas foi avaliada segundo teste t e ANOVA. RESULTADOS: Ocorreram 253.254 internações (17,2% do total) por condições cardiovasculares sensíveis à atenção primária. As taxas de hospitalização diminuíram entre os triênios: A (213,5, dp = 104,6), B (199,7, dp = 96,3) e C (150,2, dp = 76,1), com diferença entre os períodos A-C e B-C (p < 0,001). Porte populacional municipal não influenciou o comportamento das taxas. Municípios próximos à capital e aqueles da região metropolitana apresentaram maiores taxas (p < 0,001). Em todos os percentis do Índice de Condições de Vida e Saúde, houve redução das taxas (p < 0,001), exceto no percentil 1. Redução foi também observada em todas as macrorregiões, exceto na região nordeste do estado. A redução das taxas ocorreu independentemente da cobertura da Saúde da Família. CONCLUSÕES: As taxas de hospitalização por condições cardiovasculares sensíveis à atenção primária diminuíram nesses municípios, independentemente da cobertura da Saúde da Família

Strategies to reengage patients lost to follow up in HIV care in high income countries, a scoping review

Background: Despite remarkable achievements in antiretroviral therapy (ART), losses to follow-up (LTFU) might prevent the long-term success of HIV treatment and might delay the achievement of the 90-90-90 objectives. This scoping review is aimed at the description and analysis of the strategies used in high-income countries to reengage LTFU in HIV care, their implementation and impact. Methods: A scoping review was done following Arksey & O'Malley's methodological framework and recommendations from Joanna Briggs Institute. Peer reviewed articles were searched for in Pubmed, Scopus and Web of Science; and grey literature was searched for in Google and other sources of information. Documents were charted according to the information presented on LTFU, the reengagement procedures used in HIV units in high-income countries, published during the last 15 years. In addition, bibliographies of chosen articles were reviewed for additional articles. Results: Twenty-eight documents were finally included, over 80% of them published in the United States later than 2015. Database searches, phone calls and/or mail contacts were the most common strategies used to locate and track LTFU, while motivational interviews and strengths-based techniques were used most often during reengagement visits. Outcomes like tracing activities efficacy, rates of reengagement and viral load reduction were reported as outcome measures. Conclusions: This review shows a recent and growing trend in developing and implementing patient reengagement strategies in HIV care. However, most of these strategies have been implemented in the United States and little information is available for other high-income countries. The procedures used to trace and contact LTFU are similar across reviewed studies, but their impact and sustainability are widely different depending on the country studied

Choice of the initial antiretroviral treatment for HIV-positive individuals in the era of integrase inhibitors

BACKGROUND: We aimed to describe the most frequently prescribed initial antiretroviral therapy (ART) regimens in recent years in HIV-positive persons in the Cohort of the Spanish HIV/AIDS Research Network (CoRIS) and to investigate factors associated with the choice of each regimen. METHODS: We analyzed initial ART regimens prescribed in adults participating in CoRIS from 2014 to 2017. Only regimens prescribed in >5% of patients were considered. We used multivariable multinomial regression to estimate Relative Risk Ratios (RRRs) for the association between sociodemographic and clinical characteristics and the choice of the initial regimen. RESULTS: Among 2874 participants, abacavir(ABC)/lamivudine(3TC)/dolutegavir(DTG) was the most frequently prescribed regimen (32.1%), followed by tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC)/elvitegravir(EVG)/cobicistat(COBI) (14.9%), TDF/FTC/rilpivirine (RPV) (14.0%), tenofovir alafenamide (TAF)/FTC/EVG/COBI (13.7%), TDF/FTC+DTG (10.0%), TDF/FTC+darunavir/ritonavir or darunavir/cobicistat (bDRV) (9.8%) and TDF/FTC+raltegravir (RAL) (5.6%). Compared with ABC/3TC/DTG, starting TDF/FTC/RPV was less likely in patients with CD4100.000 copies/mL. TDF/FTC+DTG was more frequent in those with CD4100.000 copies/mL. TDF/FTC+RAL and TDF/FTC+bDRV were also more frequent among patients with CD4<200 cells//muL and with transmission categories other than men who have sex with men. Compared with ABC/3TC/DTG, the prescription of other initial ART regimens decreased from 2014-2015 to 2016-2017 with the exception of TDF/FTC+DTG. Differences in the choice of the initial ART regimen were observed by hospitals' location. CONCLUSIONS: The choice of initial ART regimens is consistent with Spanish guidelines' recommendations, but is also clearly influenced by physician's perception based on patient's clinical and sociodemographic variables and by the prescribing hospital location

Attitudes and beliefs about obesity among healthcare professionals in Spain : European Congress on Obesity (ECO Online 2021). 28th Congress, 10-13 May, 2021. ABSTRACTS

Introduction: Excess use of digital devices and time spent with screens might negatively influence several lifestyle behaviors in adolescents which in turn can cumulatively increase the risk of obesity(1-3). A better understanding of these associations will help to focus interventions to improve present and future health outcomes of adolescents. We conducted this study to examine the associations of screen time with eating habits, physical activity levels, sleep patterns, and adiposity measures in a sample of 10-17 years old adolescents in Mumbai, India. Methods: Cross-sectional study design. Adolescents (n=772) were selected from six public and six private schools and two junior colleges using a stratified random sampling method. Screen time, physical activity levels, and sleep patterns were assessed using a researcher-designed screen time questionnaire, Physical Activity Questionnaire for Children and Adolescents (PAQ-C/-A), and Pittsburg Sleep Quality Index (PSQI) respectively. Two non-consecutive 24h dietrecalls and a 35-item validated food frequency questionnaire determined the eating habits and energy and nutrient intakes. Body mass index (BMI) z scores > 1 and waist to height ratio (WHtR) > 0.5 were defined as measures of adiposity. Multivariate logistic regression models predicted the associations between screen time and lifestyle factors, stratified by sex. Results: The mean age of adolescents was 14.6 (2.4) years, 28.4% were overweight, 47.8% had WHtR > 0.5 and 76.1% reported their daily screen time to be > 2 hours. The PAQ scores were significantly higher in boys (p 0.032) and the mean sleep duration declined with age (p 2h/d was associated with unhealthy snack consumption (OR = 1.34, 95% CI = 1.03-1.72), lower fruit consumption (OR = 1.8, 95% CI = 1.54-2.01) and higher mean carbohydrate intakes (OR = 1.51, 95% CI = 1.44-1.67). The odds of insufficient sleep duration (2h/d and an overall screen time > 4 h/d predicted lower mean PAQ summary scores (OR = 4.1, 95% CI = 3.78-4.24). Attending private schools (OR = 1.63 (95% CI = 1.04-1.99), watching television while eating > 2h/d (OR = 1.34 (95% CI = 1.03-1.72) and having higher sleep related daytime dysfunction scores (OR = 1.25 (95% CI = 1.13-2.09) predicted higher WHtR. Additionally, being overweight was significantly associated with higher screen addiction scores (p < 0.001). Conclusion: In adolescents, excess screen time predicted unhealthy eating habits, reduced sleep duration, and greater adiposity. Results support a need to develop interventions targeted at reducing screen time to leverage better lifestyle behaviors and lower obesity risk in adolescents
