RESUMO

BACKGROUND: Overdose is a leading cause of morbidity and mortality among people who inject drugs. Illicitly manufactured fentanyl is now a major driver of opioid overdose deaths. METHODS: Semi-structured interviews were conducted with 23 participants (19 persons who inject drugs and 4 service providers) from rural southern Illinois. Data were analyzed using constant comparison and theoretical sampling methods. RESULTS: Participants were concerned about the growing presence of fentanyl in both opioids and stimulants, and many disclosed overdose experiences. Strategies participants reported using to lower overdose risk included purchasing drugs from trusted sellers and modifying drug use practices by partially injecting and/or changing the route of transmission. Approximately half of persons who inject drugs sampled had heard of fentanyl test strips, however fentanyl test strip use was low. To reverse overdoses, participants reported using cold water baths. Use of naloxone to reverse overdose was low. Barriers to naloxone access and use included fear of arrest and opioid withdrawal. CONCLUSIONS: People who inject drugs understood fentanyl to be a potential contaminant in their drug supply and actively engaged in harm reduction techniques to try to prevent overdose. Interventions to increase harm reduction education and information about and access to fentanyl test strips and naloxone would be beneficial.

RESUMO

The landscape of human immunodeficiency virus (HIV) epidemiology and treatment is ever-changing, with the widespread and evolving use of antiretroviral therapy (ART). With timely ART, people living with HIV (PLWH) are nearing the life expectancies and the functionality of the general population; nevertheless, the effects of HIV and ART on cardiovascular health remain under investigation. The pathophysiology of HIV-related cardiomyopathy and heart failure (HF) have historically been attributed to systemic inflammation and changes in cardiometabolic function and cardiovascular architecture. Importantly, newer evidence suggests that ART also plays a role in modulating the process of HIV-related cardiomyopathy and HF. In the short term, newer highly active ART (HAART) seems to have cardioprotective effects; however, emerging data on the long-term cardiovascular outcomes of certain HAART medications, i.e., protease inhibitors, raise concerns about the potential adverse effects of these drugs in the clinical course of HIV-related HF. As such, the traditional phenotypes of dilated cardiomyopathy and left ventricular systolic failure that are associated with HIV-related heart disease are incrementally being replaced with increasing rates of diastolic dysfunction and ischemic heart disease. Moreover, recent studies have found important links between HIV-related HF and other clinical and biochemical entities, including depression, which further complicate cardiac care for PLWH. Considering these trends in the era of ART, the traditional paradigms of HIV-related cardiomyopathy and HF are being called into question, as is the therapeutic role of interventions such as ventricular assist devices and heart transplantation. In all, the mechanisms of HIV-related myocardial damage and the optimal approaches to the prevention and the treatment of cardiomyopathy and HF in PLWH remain under investigation.

RESUMO

Background: Disparities in treatment and outcomes of infective endocarditis (IE) between people who use drugs (PWUD) and non-PWUD have been reported, but long-term data on cardiovascular and cerebrovascular outcomes are limited. We aim to compare 5-year rates of mortality, cardiovascular and cerebrovascular events after IE between PWUD and non-PWUD. Methods: Using data from the TriNetX Research Network, we examined 5-year cumulative incidence of mortality, myocardial infarction, heart failure, atrial fibrillation/flutter, ventricular tachyarrhythmias, ischemic stroke, and intracranial hemorrhage in 7132 PWUD and 7132 propensity score-matched non-PWUD patients after a first episode of IE. We used the Kaplan−Meier estimate for incidence and Cox proportional hazards models to estimate relative risk. Results: Matched PWUD were 41 ± 12 years old; 52.2% men; 70.4% White, 19.8% Black, and 8.0% Hispanic. PWUD had higher mortality vs. non-PWUD after 1 year (1−3 year: 9.2% vs. 7.5%, p = 0.032; and 3−5-year: 7.3% vs. 5.1%, p = 0.020), which was largely driven by higher mortality among female patients. PWUD also had higher rates of myocardial infarction (10.0% vs. 7.0%, p < 0.001), heart failure (19.3% vs. 15.2%, p = 0.002), ischemic stroke (8.3% vs. 6.3%, p = 0.001), and intracranial hemorrhage (4.1% vs. 2.8%, p = 0.009) compared to non-PWUD. Among surgically treated PWUD, interventions on the tricuspid valve were more common; however, rates of all outcomes were comparable to non-PWUD. Conclusions: PWUD had higher 5-year incidence of cardiovascular and cerebrovascular events after IE compared to non-PWUD patients. Prospective investigation into the causes of these disparities and potential harm reduction efforts are needed.

RESUMO

BACKGROUND: Current literature reports better short-term mortality rates in mitral valve repair over replacement in elderly patients. However, valve durability, postoperative complications, and reintervention rates in these cohorts remain understudied. As such, we aimed to investigate 5-year rates of mortality and reoperation after initial mitral repair or replacement in elderly patients. METHODS: Using the TriNetX Research Network database, we identified patients aged ≥70 who underwent mitral valve repair or replacement for nonrheumatic mitral insufficiency between January 2010 and December 2020. We 1:1 propensity score-matched cohorts for 33 covariates including demographics, comorbidities, and surgical history. After matching, we compared 5-year mortality and reoperation rates between cohorts using Kaplan-Meier estimates and multivariable Cox proportional hazards models. RESULTS: We compared 823 mitral valve repair patients to a propensity score-matched cohort of 823 mitral valve replacement patients over a 5-year follow-up period. All variables of interest were adequately matched. Cumulative 5-year mortality rate was significantly lower among mitral valve repair patients (17.0% vs. 24.9%; hazard ratio [HR]: 0.66, 95% confidence interval [95% CI]: 0.51-0.87, p < 0.0025). Reoperation rates at 5-year did not differ (2.6% vs. 2,1%; HR: 1.34, 95% CI: 0.67-2.68, p = 0.401). CONCLUSIONS: We observed lower 5-year mortality rates and nonsignificantly different reoperation rates among elderly patients with mitral regurgitation undergoing mitral valve repair compared to replacement. Our data support the current understanding that mitral valve repair should be considered as the first treatment line whenever possible, even in elderly patients.

RESUMO

BACKGROUND: Data on the efficacy of endovascular thoracic endovascular aneurysm repair (TEVAR) versus open surgical repair for chronic aortic pathology in patients with connective tissue disorders are limited. In particular, few studies have examined outcomes of TEVAR versus open repair for intact descending thoracic aortic aneurysms (DTAA) in this subset of patients beyond index hospitalization. Therefore, we investigate 5-year outcomes of TEVAR and open surgical repair of intact DTAAs in patients with known connective tissue disorders. METHODS: Using the TriNetX Data Network, a global federated database of over 75 million patients, we conducted a retrospective cohort study of patients with connective tissue disorders and intact DTAAs, treated initially with either TEVAR or open surgery. Eligible patients were 1:1 propensity score-matched for several preoperative co-variates including demographics, surgical history, and comorbidities. We calculated and compared 5-year cumulative incidence and hazards of death, re-intervention, aortic dissection, renal failure, stroke, intracranial hemorrhage, paraplegia, and limb ischemia using the Kaplan-Meier method and Cox proportional hazards models. RESULTS: We identified 55 patients treated with TEVAR and 200 treated with open surgery. After matching, we compared 46 patients in each cohort. After matching, only incidence of re-intervention via endovascular approach was significantly higher among patients in the TEVAR cohort (27.1% vs. 4.8%, P = 0.009). Rates and hazards of other outcomes were higher in the TEVAR group, however, differences were not statistically significant. CONCLUSIONS: Patients treated with TEVAR had numerically higher rates of adverse outcomes compared to open surgical patients, however only the difference in re-intervention rate was statistically significant. Given the evolving landscape of endovascular intervention, greater-powered studies are needed to determine the safety and efficacy of TEVAR for intact DTAAs in a select subset of connective tissue disorder patients.

RESUMO

BACKGROUND AND AIM OF STUDY: The rising rates of drug use and associated cardiovascular complications, particularly infective endocarditis, have led to poorer health outcomes for people who use drugs (PWUD). The objectives of this scoping review were to identify (1) attitudes of cardiac surgeons toward PWUD and (2) challenges faced in the surgical treatment of drug use-related disease. METHODS: A comprehensive literature search of three databases was performed with this assistance of a medical librarian. Articles were screened and analyzed for common themes by two independent authors. After literature review, a scoping review was conducted according to preferred reporting items for systematic reviews and meta-analyses and Joanna Briggs Institute guidelines, summarizing existing evidence. RESULTS: Analysis of 35 qualified articles revealed eight themes regarding the perspectives and practices of cardiac surgeons toward PWUD: (1) need for multidisciplinary care teams (45.7%); (2) insufficient resources for treatment of underlying substanceuse disorders (40.0%); (3) stigma toward PWUD (37.1%); (4) willingness of surgeons to operate (31.4%); (5) incomplete guidelines for surgical management of drug-use related infective endocarditis (17.1%); (6) recognizing the importance of psychosocial factors (14.3%); (7) use of drug abstinence contracts (14.3%); and (8) use of stigmatizing language to describe PWUD and/or sterile injection (40.0%). CONCLUSIONS: Provision of equitable care for PWUD requires effort from multiple disciplines including cardiothoracic surgeons, infectious disease specialists, addiction medicine specialists, and social workers. Additionally, further research is needed to gather sufficient data for evidence-based guidelines in the treatment of cardiac complications in PWUD.

RESUMO

Pre-exposure prophylaxis (PrEP) is a medication that prevents HIV acquisition, yet PrEP uptake has been low among people who inject drugs. Stigma has been identified as a fundamental driver of population health and may be a significant barrier to PrEP care engagement among PWID. However, there has been limited research on how stigma operates in rural and urban settings in relation to PrEP. Using in-depth semi-structured qualitative interviews (n = 57) we explore PrEP continuum engagement among people actively injecting drugs in rural and urban settings. Urban participants had more awareness and knowledge. Willingness to use PrEP was similar in both settings. However, no participant was currently using PrEP. Stigmas against drug use, HIV, and sexualities were identified as barriers to PrEP uptake, particularly in the rural setting. Syringe service programs in the urban setting were highlighted as a welcoming space where PWID could socialize and therefore mitigate stigma and foster information sharing.

RESUMO

Introduction/Objectives: The incidence of hepatitis C (HCV) infection is rising among people who inject drugs (PWID). Even in the context of known HCV prevention and treatment strategies, some PWID remain unengaged in HCV care. This study aimed to identify and characterize experiences and perceptions of PWID regarding the acceptability and effectiveness of HCV testing and treatment at a local syringe service program (SSP). Methods: A total of 36 PWID participated in semi-structured interviews at an SSP in New York City. Interviews were audio-recorded, transcribed, and coded by three coders, following a constructivist grounded theory approach. Relevant themes were identified as they emerged from the data. Results: Interviews with PWID revealed three themes related to the impact of SSPs on HCV care: (1) non-stigmatizing SSP environments, (2) the role of SSPs in improving HCV knowledge, and (3) acceptability of SSPs as sites for HCV care among PWID. Discussion: This paper contributes to the ongoing understanding that SSPs provide a well-accepted source of HCV services for PWID. Participants believed that SSPs are accessible and effective sites for HCV care, and suggested that stigma among PWID continues to affect receipt of HCV care in traditional settings. Conclusions: Understanding attitudes and beliefs of PWID regarding the effectiveness of SSPs as sites for HCV care is crucial for the development of focused strategies to reduce HCV transmission, and to ultimately achieve HCV elimination. Given this, further research is warranted investigating how best to improve HCV care at harm reduction sites such as SSPs.

RESUMO

BACKGROUND: People who inject drugs (PWID) are a medically and socially vulnerable population with a high incidence of overdose, mental illness, and infections like HIV and hepatitis C. Existing literature describes social and economic correlations to increased health risk, including stigma. Injection drug use stigma has been identified as a major contributor to healthcare disparities for PWID. However, data on this topic, particularly in terms of the interface between enacted, anticipated, and internalized stigma, is still limited. To fill this gap, we examined perspectives from PWID whose stigmatizing experiences impacted their views of the healthcare system and syringe service programs (SSPs) and influenced their decisions regarding future medical care. METHODS: Semi-structured interviews conducted with 32 self-identified PWID in New York City. Interviews were audio recorded and transcribed. Interview transcripts were coded using a grounded theory approach by three trained coders and key themes were identified as they emerged. RESULTS: A total of 25 participants (78.1%) reported at least one instance of stigma related to healthcare system engagement. Twenty-three participants (71.9%) reported some form of enacted stigma with healthcare, 19 participants (59.4%) described anticipated stigma with healthcare, and 20 participants (62.5%) reported positive experiences at SSPs. Participants attributed healthcare stigma to their drug injection use status and overwhelmingly felt distrustful of, and frustrated with, medical providers and other healthcare staff at hospitals and local clinics. PWID did not report internalized stigma, in part due to the availability of non-stigmatizing medical care at SSPs. CONCLUSIONS: Stigmatizing experiences of PWID in formal healthcare settings contributed to negative attitudes toward seeking healthcare in the future. Many participants describe SSPs as accessible sites to receive high-quality medical care, which may curb the manifestation of internalized stigma derived from negative experiences in the broader healthcare system. Our findings align with those reported in the literature and reveal the potentially important role of SSPs. With the goal of limiting stigmatizing interactions and their consequences on PWID health, we recommend that future research include explorations of mechanisms by which PWID make decisions in stigmatizing healthcare settings, as well as improving medical care availability at SSPs.

RESUMO

Cardiovascular disease, the leading cause of death in the USA, poses a unique and multilateral burden to racial/ethnic minorities. The admixture of comorbid conditions, structural barriers, and psychosocial standing complicates the prevention, diagnosis, and management of cardiovascular disease in racial/ethnic minority populations and requires newer approaches to reduce existing disparities. A discussion of the cardiovascular disease risk burden is presented, along with an overview of multi-stratified considerations for improving racial/ethnic minority cardiovascular health via community engagement.

RESUMO

Relatively little research has been conducted on quantitative electroencephalography (QEEG) activity in patients with psychosis÷schizophrenia, especially in populations at-risk for the illness. Further studies are needed, in order to offer a possible endophenotypic marker of the cerebral functioning, associated with psychosis÷schizophrenia, in correlation with the neuroimaging, the neurocognitive, biochemical, molecular genetic tests, clinical aspects and the EEG activity from the same subjects. The aim was to investigate the role the QEEG abnormalities play in the etiology of psychosis÷schizophrenia, whether it can provide an endophenotype for psychosis and to make some correlations with the results obtained through magnetic resonance (MR) spectroscopy, for proper early detection and intervention. The prospective research was performed in the University Clinic of Child and Adolescent Psychiatry, Timisoara, Romania, involving 55 children with schizophrenia or ultra high-risk (UHR) for psychosis (groups 1, 2, 3 and 4) and 55 children as healthy controls (group 5). Groups 1 and 2 (28 children) are diagnosed with schizophrenia, groups 3 and 4 are UHR for psychosis (27 children), and group 5 represents healthy controls. Groups 1 and 3 had convulsive seizures in their personal history. We noticed: through the QEEG, numerous patterns of theta and delta activity, the diminished amplitude of the alpha band waves and the diminished alpha activity; also, the onset of psychosis was earlier at those presenting convulsive seizures in their personal history (groups 1 and 3); also, specific neuroimagistic abnormalities and modifications. The cerebral lesions, appearing during the development, raise the liability for schizophrenia. The high-risk for schizophrenia is correlated with the personal history of epilepsy, as well as with the family risk for psychosis.
