RESUMEN
Objectives: This study aimed to estimate the disease burden of BSIs caused by gram-negative bacteria (GNB-BSIs) in a Brazilian hospital from 2015 to 2019, measured in disability-adjusted life-years (DALYs). Methods: A retrospective cohort study of adult patients with GNB-BSI was conducted from April 01, 2015 to March 31, 2019. This study was carried out in a 356-bed private hospital with a 68-bed medical intensive care unit located in Salvador, Brazil. Demographic and clinical data were collected through a review of medical records. DALYs were estimated using Monte Carlo Simulations, using life tables for Brazilians estimated for 2020 and the Global Burden of Diseases 2010 (GBD 2010). Results: A total of 519 GNB-BSI episodes in 498 individuals were identified. The mean age was 59.92 ± 17.97 years, with 61.1% being male. The most common bacterial infections were Klebsiella pneumoniae and Escherichia coli (66.5%), whereas carbapenem-resistant gram-negative bacteria (CR-GNB) accounted for 32.7% of cases. The highest overall DALYs were observed in 2018 (752, 95% confidence interval [CI]: 520-1021 with Brazilian Life Tables and 782, 95% CI: 540-1062 with GBD 2010). Infections due to CR-GNB had the highest DALYs, particularly, in 2017, reaching 7050 (95% CI: 3200-12,150 with Brazilian Life Tables and 7350, 95% CI: 3350-12,700 with GBD 2010) DALYs per 1000 patient days and an estimated mortality rate of 40% per 1000 patient days. Conclusions: The persistently high DALYs associated with CR-GNB raise alarming concerns, potentially leading to over 300 deaths per 1000 patient days in the coming years. These findings underscore the urgency of addressing GNB-BSI as a significant public health issue in Brazil. These results are expected to provide helpful information for public health policymakers to prioritize interventions for infections due to antibiotic-resistant bacteria.
RESUMEN
Objective: This study aimed to assess the association of body mass index (BMI) with anal high-risk human papillomavirus (HR-HPV) and biopsy-confirmed histologic anal high-grade squamous intraepithelial lesions (HSIL) among a clinic-based sample of Hispanics in Puerto Rico. Methods: This cross-sectional study evaluated medical records of adults who received services at the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center between October 2014 and December 2022. The study included 543 records with complete clinical information regarding anal HR-HPV and anal HSIL status. Chi-square and logistic regression analyses were performed. Results: Mean age of participants was 44.10 ± 13.24 years, 65.2% were men, 71.7% were HIV-infected, 74.4% had anal HR-HPV infection, and 37.9% had biopsy-confirmed HSIL. Regarding BMI, 2.4% were underweight, 31.9% normal weight, and 39.0 % overweight; while 17.3 % had class I, 5.2% class II, and 4.2% class III obesity. No significant association was observed between BMI and anal HR-HPV infection in adjusted analyses. Lower odds of anal HSIL were observed among overweight individuals (OR: 0.63, 95% CI: 0.41 - 0.99) and those with class II/III obesity (OR: 0.48, 95% CI: 0.22 - 1.01) compared to adults with underweight/normal BMI, after adjusting for potential confounders. No significant association was observed for class I obesity. Conclusion: BMI was not associated with anal HR-HPV infection. Overweight and obese individuals had lower odds of having anal HSIL than adults with underweight/normal BMI. This finding could suggest underdiagnosis of HSIL among overweight/obese individuals, or reduced risk in this group.
