Clinics (Sao Paulo) 2023; 78:100269. [PMID: 37557004 PMCID: PMC10432905 DOI: 10.1016/j.clinsp.2023.100269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 07/25/2023] [Accepted: 07/27/2023] [Indexed: 08/11/2023] Open
Abstract
OBJECTIVES The authors evaluated mortality and indices of cost of care among inpatients with Atrial Fibrillation (AF) and a diagnosis of a Temperature-Related Illness (TRI). The authors also assessed trends in the prevalence of TRIs among AF hospitalizations. METHODS In this cross-sectional study, the authors used discharge data from the Nationwide Inpatient Sample (NIS) collected between January 2005 and September 2015 to identify patients with a diagnosis of AF and TRI. Outcomes of interest included in-hospital mortality, invasive mechanical ventilation, hospital length of stay, and cost of hospitalization. RESULTS A total of 37,933 encounters were included. The median age was 79 years. Males were slightly overrepresented relative to females (54.2% vs. 45.8%, respectively). Although Blacks were only 6.6% of the cohort, they represented 12.2% of the TRI cases. Compared to non-TRI-related hospitalizations, a diagnosis of a TRI was associated with an increased likelihood of invasive mechanical ventilation (16.5% vs. 4.1%, p < 0.001), longer length-of-stay (5 vs. 4 days, p < 0.001), higher cost of care (10,082 vs. 8,607, in US dollars p < 0.001), and increased mortality (18.6% vs. 5.1%, p < 0.001). Compared to non-TRI, cold-related illness portends higher odds of mortality 4.68, 95% Confidence Interval (4.35-5.04), p < 0.001, and heat-related illness was associated with less odds of mortality, but this was not statistically significant 0.77 (0.57-1.03), p = 0.88. CONCLUSION The occurrence of TRI among hospitalized AF patients is small but there is an increasing trend in the prevalence, which more than doubled over the decade in this study. Individuals with AF who are admitted with a TRI face significantly poorer outcomes than those admitted without a TRI including higher mortality. Cold-related illness is associated with higher odds of mortality. Further research is required to elucidate the pathogenic mechanisms underlying these findings and identify strategies to prevent TRIs in AF patients.

Abstract
The need to improve access to health services for the transgender community has become evident, especially concerning cardiovascular risk, which is higher compared to the general population. Surgical procedures and hormone therapies are common in this population to affirm gender identity, but they pose challenges as they are associated with disruptions in lipid metabolism, body fat concentration, and insulin resistance. Additionally, there is an increased risk of adverse cardiovascular events such as venous thromboembolism, stroke, and myocardial infarction. The influence of sex hormones on the electrophysiological properties of the heart has been studied, highlighting gender differences that may predispose the transgender population to cardiac arrhythmias. Exogenous hormone therapy, for both transgender women and men, can affect the QT interval and increase the risk of arrhythmias, including atrial fibrillation. Although the incidence of arrhythmias in the transgender population is not entirely clear, evidence suggests the need for careful cardiovascular monitoring and consideration of risk factors before initiating hormone therapies.

Abstract
BACKGROUND The development of highly active anti-retroviral therapy (HAART) has markedly prolonged the life expectancy of individuals with human immunodeficiency virus (HIV). The prevalence of age-related cardiovascular disease (CVD) and arrhythmias is therefore expected to increase among the HIV-positive population. OBJECTIVES We aimed to assess the trends in prevalence, and inpatient outcomes among patients with HIV and atrial fibrillation (AF). METHODS Using ICD-9-CM coding, we identified 38,252,858 HIV-negative and 31,224 HIV-positive encounters with AF from the National Inpatient Sample (NIS) database from January 2005 to September 2015. Trends in prevalence of HIV in AF patients, length and cost of hospital stay, and inpatient mortality, were determined. t-Test was used for continuous variables and Chi-square test for categorical variables. Final multivariable logistic regression models were constructed to determine predictors of outcomes. RESULTS Among the 31,224 HIV-positive encounters, 78.6% were males. The median age was 56 years for HIV-positive patients and 78 years for HIV-negative patients. Black patients were markedly overrepresented among HIV-positive as compared to HIV-negative hospitalisations (48.6 vs. 7.6%). The prevalence of alcohol and drug use, smoking, chronic kidney disease, chronic liver disease, and cancer was higher among HIV-positive as compared to HIV-negative patients. The prevalence of HIV among the AF hospitalisations increased from 2005 to 2015. As compared to HIV-negative patients, individuals with HIV demonstrated increased inpatient mortality (9.2 vs. 5.1%), longer length of stay (6 [3-11] vs. 4 [2-7] days), and increased cost of treatment ($12,464 vs. $8606). CONCLUSION The prevalence of HIV among patients with AF increased between 2005 and 2015. As compared to HIV-negative individuals with AF, a diagnosis of HIV was associated with increased inpatient mortality, length of stay, and cost of care. Future research on the underlying mechanisms of these findings is warranted to inform the treatment of AF in patients with HIV.

Cardiovascular outcomes in transgender individuals in Sweden after initiation of gender-affirming hormone therapy. Eur J Prev Cardiol 2022; 29:2017-2026. [PMID: 35778824 DOI: 10.1093/eurjpc/zwac133] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 06/22/2022] [Accepted: 06/28/2022] [Indexed: 11/12/2022]
Abstract
AIMS We compared the incidence of cardiovascular disease (CVD) in transgender participants with a diagnosis of gender dysphoria (GD) with and without gender-affirming hormone therapy (GAHT) to the incidence observed in the general population. METHODS AND RESULTS The population-based cohort included all individuals >10 years in Sweden linked to Swedish nationwide healthcare Registers (2006-2016). Two comparator groups without GD/GAHT were matched (1:10) on age, county of residence, and on male and female birth-assigned sex, respectively. Cox proportional models provided hazard ratios (HR) and 95% confidence intervals (CI) for CVD outcomes. Among 1779 transgender individuals (48% birth-assigned males [AMAB], 52% birth-assigned females [AFAB]) 18 developed CVD, most of which were conduction disorders. The incidence of CVD for AFAB individuals with GD was 3.7 per 1000 person-years (95%CI: 1.4-10.0). AMAB individuals with GD had an incidence of CVD event of 7.1 per 1000 person-years (95%CI: 4.2-12.0). The risk of CVD event was 2.4 times higher in AMAB individuals (HR: 2.4, 95%CI: 1.3-4.2) compared to cisgender women, and 1.7 higher compared to cisgender men (HR: 1.7, 95%CI: 1.0-2.9). Analysis limited to transgender individuals without GAHT yielded similar results to those with GAHT treatment. CONCLUSION The incidence of CVD among GD/GAHT individuals was low, although increased compared to matched individuals without GD and similar to the incidence among GD/no GAHT individuals, thus not lending support for a causal relationship between treatment and CVD outcomes. Larger studies with longer follow-up are needed to verify these findings, as well as possible effect modification by comorbidity.

Abstract
Significant variations from the normal QT interval range of 350 to 450 milliseconds (ms) in men and 360 to 460 ms in women increase the risk for ventricular arrhythmias. This difference in the QT interval between men and women has led to the understanding of the influence of sex hormones on the role of gender-specific channelopathies and development of ventricular arrhythmias. The QT interval, which represents the duration of ventricular repolarization of the heart, can be affected by androgen levels, resulting in a sex-specific predilection for acquired and inherited channelopathies such as acquired long QT syndrome in women and Brugada syndrome and early repolarization syndrome in men. Manipulation of the homeostasis of these sex hormones as either hormonal therapy for certain cancers, recreational therapy or family planning and in transgender treatment has also been shown to affect QT interval duration and increase the risk for ventricular arrhythmias. In this review, we highlight the effects of endogenous and exogenous sex hormones in the physiological and pathological states on QTc variation and predisposition to gender-specific pro-arrhythmias.
