Neighborhood-level Determinants of Delayed HIV Diagnosis and Survival among HIV-positive Latinos, Florida 2000-2011

The purpose of this study was to estimate disparities in late human immunodeficiency virus (HIV) diagnosis and all-cause mortality among varying populations of HIV-positive Latinos, and to identify neighborhood-level predictors. Florida HIV surveillance data for years 2000–2011 were merged with 2007–2011 American Community Survey (ACS) data. Multilevel logistic regressions were used to estimate adjusted odds ratios (aOR) for late HIV diagnosis (acquired immunodeficiency syndrome within 3 months of HIV diagnosis). Multilevel weighted Cox regressions were used to estimate adjusted hazard ratios (aHR) for mortality. Of 5522 Latinos diagnosed 2007–2011, males were at increased odds of late diagnosis compared with females (aOR 1.37, 95% confidence interval [CI] 1.13-1.67). Associated factors included residing in the lowest quartile of neighborhood education for females, and in the 3 highest quartiles of unemployment for males. Foreign-born compared with United States (US)-born Latinos were also at risk (aOR 1.24, 95% CI 1.08-1.42). Among foreign-born, residing in areas wit

Black–White Latino Racial Disparities in HIV Survival, Florida, 2000–2011

This research aimed to estimate Black/White racial disparities in all-cause mortality risk among HIV-positive Latinos. Florida surveillance data for Latinos diagnosed with HIV (2000–2008) were merged with 2007–2011 American Community Survey data. Crude and adjusted hazard ratios (aHR) were calculated using multi-level Cox regression. Of 10,903 HIV-positive Latinos, 8.2% were Black and 91.9% White. Black Latinos were at increased mortality risk compared with White Latinos after controlling for individual and neighborhood factors (aHR 1.40, 95% confidence interval (CI) 1.21–1.62). In stratified analyses, risk factors for Black Latinos included: age ¥60 years compared with ages 13–19 (aHR 4.63, 95% CI 1.32–16.13); US birth compared with foreign birth (aHR 1.56, 95% CI 1.16–2.11); diagnosis of AIDS within three months of HIV diagnosis (aHR 3.53, 95% CI 2.64–4.74); residence in the 3rd (aHR 1.82, 95% CI 1.13–2.94) and 4th highest quartiles (aHR 1.79, 95% CI 1.12–2.86) of neighborhood poverty compared with the lowest quartile; and residence in neighborhood with 25%–49% (aHR 1.59, 95% CI 1.07–2.42) and ¥50% Latinos compared with \u3c25% Latinos (aHR 1.58, 95% CI 1.03–2.42). Significant racial disparities in HIV survival exist among Latinos. Differential access to—and quality of—care and perceived/experienced racial discrimination may be possible explanations

Neighborhood Latino ethnic density and mortality among HIV- positive Latinos by birth country/region, Florida, 2005–2008

OBJECTIVE: Lower mortality for Latinos has been reported in high Latino density areas. The objective was to examine the contribution of neighborhood Latino density to mortality among HIV-positive Latinos. METHODS: Florida HIV surveillance data for 2005–2008 were merged with 2007–2011 American Community Survey data using zip code tabulation areas. Hazard ratios (HR) were calculated using multi-level weighted Cox regression and adjusted for individual-level factors and neighborhood poverty. RESULTS: Of 4649 HIV-positive Latinos, 11.8% died. There was no difference in mortality risk across categories of Latino ethnic density for Latinos as a whole. There were subgroup effects wherein mortality risk differed by ethnic density category for Latinos born in some countries/regions. Residing in an area with ≥50% Latinos compared with <25% was associated with increased mortality risk for Latinos born in Puerto Rico (HR 1.67; 95% CI [1.01–2.70]). Residing in an area where Mexicans were the majority Latino group was associated with increased mortality risk for Latinos born in Mexico (HR 3.57; 95% CI [1.43–10.00]). CONCLUSIONS: The survival advantage seen among the Latino population in high Latino density areas was not seen among HIV-positive Latinos. Research is needed to determine if this may be related to stigma or another mechanism

Individual and neighborhood predictors of mortality among HIV-positive Latinos with history of injection drug use, Florida, 2000–2011

BACKGROUND: The objectives are to examine disparities in all-cause mortality risk among HIV-positive Latinos with injection drug use (IDU) history, and to identify individual- and neighborhood-level predictors. METHODS: Florida surveillance data for persons diagnosed with HIV 2000–2008 were merged with 2007–2011 administrative data from the American Community Survey. Hazard ratios (HR) were calculated using multi-level weighted Cox regression adjusting for individual and neighborhood (ZCTA-level) factors. RESULTS: Of 10,989 HIV-positive Latinos, 10.3% had IDU history. Latinos with IDU history were at increased mortality risk compared with Latinos without IDU history after controlling for individual and neighborhood factors (adjusted HR [aHR] 1.61, 95% confidence interval [CI] 1.43–1.80). Factors associated with mortality for those with IDU history included: being 40–59 (aHR 6.48, 95% CI 1.41–121.05) and ≥60 years (aHR 18.75, 95% CI 3.83–356.45) compared with 13–19 years of age; being diagnosed with AIDS within 3 months of HIV (aHR 2.31, 95% CI 1.87–2.86); residing in an area with ≥50% Latinos compared with <25% Latinos (aHR 1.56, 95% CI 1.19–2.04); and residing in a rural compared with an urban area at the time of diagnosis (aHR 1.73, 95% CI 1.06–2.70). Race and neighborhood poverty were not predictors among those with IDU, but were among those without. CONCLUSION: HIV-positive Latinos with IDU history are at increased mortality risk and have unique contributing factors. Tertiary prevention strategies should target those who are older, diagnosed at later stages, and those who live in predominantly Latino and rural areas

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
