Screening and risk assessment for coronary artery disease in HIV infection: an unmet need

Construction and validation of conceptual and operational definitions of the defining characteristics of the nursing diagnosis "Ineffective health self-management" in people living with HIV/AIDS

PURPOSE

Build and validate the content of conceptual and operational definitions of the defining characteristics of the nursing diagnosis of NANDA-I "Ineffective health self-management" in people living with HIV/AIDS.

METHODS

Methodological study, with a quantitative approach. The validation was performed by 26 specialist nurses selected through the Lattes do Brazil platform. The process followed two steps: (a) proposal of new defining characteristics to the Nursing Diagnosis "Ineffective Health Self-Management" and elaboration of conceptual and operational definitions; (b) content validation of the new defining characteristics of the Nursing Diagnosis "Ineffective Health Self-Management" and the conceptual and operational definitions. Data were collected between October 2020 and May 2021.

FINDINGS

The researchers included six defining characteristics as components of the diagnosis, adding to the 10 already existing in the NANDA-I version (2021-2023). Then, the experts judged these components and 13 defining characteristics were validated using the binominal test with adequacy ratio above 85% and p value <0.05. After this stage, the conceptual and operational definitions of these defining characteristics were constructed, validating them by the content validation index ≥0.80 by the expert nurses.

CONCLUSIONS

Three new defining characteristics for Ineffective health self-management were proposed and validated by specialists. Conceptual and operational definitions of the new and current defining characteristics were elaborated and validated for people living with HIV/AIDS.

IMPLICATIONS FOR NURSING PRACTICE

The knowledge and study of the conceptual and operational definitions of nursing diagnoses can contribute to good nursing practices, assisting in the care and evaluation of nurses in the provision of care to people living with HIV/AIDS, and can avoid misunderstandings and inappropriate interpretations and can guarantee assertive clinical judgment.

Exercise ECG for coronary artery disease screening in people living with HIV

BACKGROUND

Coronary artery disease (CAD) is one of the leading causes of death among people living with HIV (PLWH). We evaluated ECG stress testing (EST) for detecting CAD in PLWH with multiple cardiovascular risk factors.

METHODS

CORDIS was a cross-sectional study conducted in PLWH. Inclusion criteria were men at least 50 years or postmenopausal women, HIV-1 RNA less than 50 copies/ml and at least one of the following cardiovascular risk factor: familial history of CAD, smoking, hypertension, hypercholesterolemia or diabetes. Patients with a previous diagnosis of CAD or with cardiac symptoms were excluded. EST was performed concomitantly with bilateral carotid color-Doppler ultrasonography (CDU) and evaluated by a cardiologist. Results were described by median (interquartile range) or frequency (%). Logistic regression was applied to evaluate predictive factors of inducible myocardial ischemia (IMI).

RESULTS

EST and CDU were performed in 309 individuals; IMI prevalence was 7.4% [95% confidence interval (CI): 5.0-11.0%]. Among patients with a normal CDU, no cases of IMI were observed. In people with abnormal CDU, IMI prevalence increased accordingly with the atherosclerotic cardiovascular disease (ASCVD) risk score: 10.2%, 16.9%, 19.7%, 27.8% and 30.4% among individuals with ASCVD score 7.5% or less, more than 7.5%, more than 10%, more than 15% and more than 20%, respectively (P for trend: 0.02). At multivariate analysis, ASCVD risk score was associated with EST suggestive of IMI (adjusted odds ratio for 1% increase = 1.08; 95% CI: 1.02-1.13, P = 0.005) and with confirmed IMI (adjusted odds ratio for 1% increase = 1.11; 95% CI: 1.04-1.19, P = 0.003).

CONCLUSION

Prevalence of IMI was 7.4% in the CORDIS study. We suggest EST as first-line screening for CAD in PLWH without cardiac symptoms, with an abnormal CDU and a high ASCVD risk score.

Ineffective health control: concept analysis

OBJECTIVES

to identify and synthesize the concept of Ineffective Health Control.

METHODS

Concept Analysis from the perspective of Walker and Avant, operationalized by an integrative review in the databases Scopus, LILACS, PubMed, CINAHL, Web of Science, Science Direct e Cochrane, using the descriptors: Adhesion to Medication; Cooperation and Adherence to Treatment and Acquired Immunodeficiency Syndrome.

RESULTS

five critical attributes were identified for the concept, namely: patient's refusal to follow the therapeutic plan; abandoning treatment and worsening signs and symptoms; difficulty in reaching agreed goals; difficulty following health professionals' guidelines; multifactorial and dynamic process.

CONCLUSIONS

the concept of Ineffective Health Control is characterized by a multifactorial and dynamic process evidenced by the patient's refusal to follow a therapeutic plan, favouring the abandonment of treatment and resulting in the worsening of signs and symptoms and failure to reach goals.

Análisis de la dislipidemia en adultos que viven con VIH

Introducción: En el contexto de las personas que viven con VIH (PVVIH), la dislipidemia es un tema que se ha venido discutiendo ampliamente, tanto por su origen multifactorial y sus implicaciones cardiovasculares, como por las posibles estrategias de prevención. De este modo, este estudio tiene por objeto evaluar la presencia de la dislipidemia en personas que viven con VIH y su asociación con aspectos sociodemográficos, actitudinales y clínicos. Materiales y Métodos: Estudio analítico, transversal realizado entre 2014 y 2016. Los datos fueron recolectados a través de entrevistas en las que se utilizaban cuestionarios y se consultaban las historias médicas. Para analizar la asociación, se utilizaron las pruebas Chi-Cuadrado y Exacto de Fisher, y la estadística Kappa para análisis de concordancia, con un nivel de significancia de p<0,05. Resultados: Participaron 340 personas en el estudio, de las cuales 59,1%, presentaron valores deseables en términos de colesterol total, 55,9% del HDL y 56,8% de triglicéridos. Las variables asociadas a la dislipidemia fueron: el colesterol total alterado y la edad a partir de 40 años (p=0,02); el HDL-c deseable y el sexo femenino (p=0,007); alteración de los triglicéridos y el tiempo de diagnóstico mayor a diez años (p=0,008); y el HDL-c deseable y la carga viral indetectable (p=0,04). Discusión: Aunque la dislipidemia sea un problema en el contexto del VIH, los valores deseables fueron más prevalentes, lo que se refleja sobre el efecto catalizador de la actividad inflamatoria causada por el VIH sobre las alteraciones lipídicas. Conclusiones: La dislipidemia en las PVVIH presentó, en su gran mayoría, valores deseables para el colesterol total, colesterol HDL y triglicéridos; y hubo una asociación entre los lípidos y los aspectos sociodemográficos y clínicos relacionados con el VIH.

Human Immunodeficiency Virus Organ Transplantation

Human immunodeficiency virus (HIV) has become a chronic disease with a near normal life span resulting in increased risk of organ failure. HIV organ transplantation is a proven and accepted intervention in appropriately selected cases. HIV-positive organ transplantation into HIV-positive recipients is in its nascent stages. Hepatitis C virus, high rates of organ rejection, and immune dysregulation are significant remaining barriers to overcome. This article provides an overview of the transplantation needs in the HIV population focusing on kidney and liver transplants.

Global and regional brain hypometabolism on FDG-PET in treated HIV-infected individuals

OBJECTIVE

To quantitatively measure brain glucose metabolism in treated HIV-positive individuals with [¹⁸F]-labeled fluorodeoxyglucose (FDG) PET/CT.

METHODS

We performed a cross-sectional comparison of FDG uptake in 47 treated HIV+ individuals, 10 age-matched controls (HIV-) sharing many of the comorbid conditions seen in the HIV+ group, and 19 age-matched healthy controls (HCs). We compared whole-brain (WB) and regional FDG standardized uptake values (SUVs) of select subcortical/central structures among the groups and correlated the values to clinical and neuropsychological assessments. A variable selection model was used to predict SUVs in HIV+ (n = 47) and in combined HIV+ and HIV- participants (n = 57).

RESULTS

We found lower WB SUVmax in HIV+ participants compared to HCs but not to HIV- participants. Among the relative SUVmean measurements (regional SUVmean/WB SUVmean), only relative thalamic uptake values were lower in HIV+ compared to HIV- participants. When HIV+ and HIV- participants were grouped, cardiovascular disease risk scores best predicted WB SUVmean and SUVmax, while HIV status best predicted thalamic relative SUVmean.

CONCLUSIONS

We identified an important role for cardiovascular disease in neuronal loss/dysfunction, as measured by FDG-PET, in treated HIV+ patients. This underscores the need for shifting the focus of clinical intervention in this vulnerable population from HIV effects alone to a wider set of comorbid conditions, mainly cardiovascular disease. Only the thalamus showed significantly lower relative uptake in the HIV+ compared to the HC and HIV- groups. This needs to be further evaluated for underlying pathophysiology and potential association with memory, executive functioning, and attention deficits seen in the HIV+ population.

HIV related stigma, perceived social support and risk of premature atherosclerosis in South Asians

Objective

This study sought to determine the association between social support and stigma experienced by HIV-positive patients and presence of subclinical cardiovascular disease.

Methods

We implemented a cross sectional study in 67 HIV-positive patients and 52 controls from a community health care center in central India. The participants underwent an in-depth survey and a clinical and laboratory assessment of cardiovascular risk. Carotid-intimal thickness (CIMT) was used as a marker of subclinical cardiovascular disease.

Results

On comparing the HIV and age and sex-matched control population, HIV patients had lower body weight (P=<0.001), and lower systolic blood pressures (P = 0.002). Despite the lack of higher cardiac risk factor prevalence and lower lipid abnormalities, HIV patients had higher right, left and average CIMT values than controls (P < 0.001 for all). HIV patients also showed higher prevalence of abnormal CIMT (≥ 0.9 mm) than controls (32% vs. 0%, P < 0.001). HIV patients with increased CIMT (n = 37) in comparison with those with normal CIMT (n = 30) were more frequently males (P = 0.023), had higher systolic blood pressures (P = 0.002), lower CD4 counts (P = 0.033) and experienced higher enacted stigma (P = 0.044). On multivariable stepwise logistic regression, systolic blood pressure (odds ratio:1.06, P = 0.002) and stigma score > 25^th percentile value (odds ratio:3.84, P = 0.037) were independent predictors of the abnormal CIMT.

Conclusions

HIV-positive patients from central India have a higher prevalence of abnormal CIMT as a marker of subclinical cardiovascular disease than the general population. This predisposition to increased cardiovascular risk may be related to complex interactions between HIV disease and stigma-related healthcare inequalities.

HIV-related cardiovascular disease: closing the gap in mortality

: This series of review articles outlines the complex cause of HIV-related cardiovascular diseases (CVDs) particularly the interactions of viral factors, complications of antiviral therapy such as metabolic derangement, and chronic systemic inflammation. These factors, directly stemming from chronic HIV infection, are important in the pathogenesis of HIV-related CVD. Addressing each issue has likely underpinned the improved morbidity and increased life expectancy enjoyed by patients in the modern era of HIV management. The global management of HIV-related CVD may, however, be simpler than previously imagined, as the disease likely follows a pathway shared by multiple systemic diseases. Other chronic systemic diseases, including diabetes, rheumatoid arthritis, and autoimmune disease, share numerous pathophysiological mechanisms with HIV and provoke similar cardiac complications. CVD risk management in patients living with HIV (PLHIV) may be optimized by drawing upon existing knowledge of chronic systemic diseases which may open up new concepts in treatment and address the current shortfalls in cardiovascular management of PLHIV.
