RESUMO

BACKGROUND: Understanding why patients experience loss to follow-up (LTFU) is essential for TB control. This analysis examines the impact of travel distance to RR-TB treatment on LTFU, which has yet to be analyzed within South Africa. METHODS: We retrospectively analyzed 1436 patients treated for RR-TB at ten South African public hospitals. We linked patients to their residential ward using data reported to NHLS and maps available from the Municipal Demarcation Board. Travel distance was calculated from each patient's ward centroid to their RR-TB treatment site using the georoute command in Stata. The relationship between LTFU and travel distance was modeled using multivariable logistic regression. RESULTS: Among 1436 participants, 75.6% successfully completed treatment and 24.4% were LTFU. The median travel distance was 40.96 km (IQR: 17.12, 63.49). A travel distance > 60 km increased odds of LTFU by 91% (p = 0.001) when adjusting for HIV status, age, sex, education level, employment status, residential locale, treatment regimen, and treatment site. CONCLUSION: People living in KwaZulu-Natal and Eastern Cape travel long distances to receive RR-TB care, placing them at increased risk for LTFU. Policies that bring RR-TB treatment closer to patients, such as further decentralization to PHCs, are necessary to improve RR-TB outcomes.

RESUMO

Tuberculosis (TB) stigma is one barrier to TB testing, treatment uptake and treatment completion. Therefore, stigma measurement must be approached through rigorous scientific methodology in order to accurately and reliably estimate the impact of TB stigma on treatment outcomes. The aim of this systematic review is to evaluate the methods and instruments used to measure TB stigma and interrogate strategies used to culturally validate measures of TB stigma in global research. Two reviewers used the PRISMA method to extract and analyze the existing body of literature on TB stigma in Sub-Saharan Africa. A thorough search was performed using three data bases generating 2,302 independent studies. After systematic screening, this review includes 28 studies. Of those studies, 13 used a psychometrically validated instrument while 15 used informal questionnaires or proxy variables to measure stigma. Psychometric appraisal was limited due to the number of studies that measured stigma using unvalidated questionnaires or proxy variables. The Patient and Community Perceptions of TB scales validated by Van Rie et al. were the most commonly used instruments to measure TB stigma; additionally, many instruments were not culturally or linguistically validated in Sub-Saharan Africa. Our appraisal emphasizes the need for reliable and valid instruments to measure TB stigma in low- and middle-income countries most affected by TB.

RESUMO

BACKGROUND: Almost twenty percent of adults with COVID-19 develop Long COVID, leading to prolonged symptoms and disability. Understanding the supportive needs of people with Long COVID is vital to enacting effective models of care and policies. DESIGN/METHODS: This qualitative sub-study explored the experiences of people with Long COVID and their unmet needs. Participants enrolled in a larger study to evaluate the post-acute cardiovascular impacts of COVID-19 were invited to participate in subsequent in-depth interviews. Participants were enrolled purposively until saturation at 24 participants. Data were analyzed using thematic content analysis. RESULTS: Participants focused on adaptations to life with Long COVID and their unmet needs in different life spheres. Three domains, 1) occupational and financial; 2) healthcare-related; and 3) social and emotional support, emerged as areas affecting quality of life. Although participants were motivated to return to work for financial and personal reasons, Long COVID symptoms often resulted in the inability to perform tasks required by their existing jobs, and unemployment. Those who maintained employment through employer accommodations still needed additional support. Participants encountered diagnostic challenges, challenges in accessing specialty appointments, insurance loopholes, high healthcare costs, and medical skepticism. Existing social networks provided support for completing daily tasks; however, those with Long COVID typically turned to others with similar lived experiences for emotional support. Participants found government support programs inadequate and difficult to access in all three domains. DISCUSSION: We propose a five-pronged policy approach to support persons with Long COVID. These overarching recommendations are (1) improve public awareness of Long COVID; (2) improve clinical care quality and access; (3) implement additional school and workplace accommodations; (4) strengthen socioeconomic benefits and social services; and (5) improve research on Long COVID.

RESUMO

While stigma experienced by people living with HIV (PLWH) is well documented, intersectional stigma and additional stigmatized identities have not received similar attention. The purpose of this metasynthesis is to identify salient stigmatized intersections and their impact on health outcomes in PLWH in sub-Saharan Africa. Using Sandelowski and Barroso's metasynthesis method, we searched four databases for peer-reviewed qualitative literature. Included studies (1) explored personal experiences with intersecting stigmas, (2) included ≥1 element of infectious disease stigma, and (3) were conducted in sub-Saharan Africa. Our multinational team extracted, aggregated, interpreted, and synthesized the findings. From 454 screened abstracts, the 34 studies included in this metasynthesis reported perspectives of at least 1258 participants (282 men, 557 women, and 109 unspecified gender) and key informants. From these studies, gender and HIV was the most salient stigmatized intersection, with HIV testing avoidance and HIV-status denial seemingly more common among men to preserve traditional masculine identity. HIV did not threaten female identity in the same way with women more willing to test for HIV, but at the risk of abandonment and withdrawal of financial support. To guard against status loss, men and women used performative behaviors to highlight positive qualities or minimize perceived negative attributes. These identity management practices ultimately shaped health behaviors and outcomes. From this metasynthesis, the Stigma Identity Framework was devised for framing identity and stigma management, focusing on role expectation and fulfillment. This framework illustrates how PLWH create, minimize, or emphasize other identity traits to safeguard against status loss and discrimination. Providers must acknowledge how stigmatization disrupts PLWH's ability to fit into social schemas and tailor care to individuals' unique intersecting identities. Economic security and safety should be considered in women's HIV care, while highlighting antiretrovirals' role in preserving strength and virility may improve care engagement among men.

RESUMO

BACKGROUND: Patients with ESKD treated with hemodialysis in the United States have persistently higher rates of nonadherence compared with patients in other developed countries. Nonadherence is associated with an increased risk of death and higher medical expenditure. There is an urgent need to address it with feasible, effective interventions as the prevalence of patients on hemodialysis in the United States continues to grow. However, published adherence interventions demonstrate limited long-term efficacy. METHODS: We conducted a synthesis of qualitative studies on adherence to hemodialysis treatment, medications, and fluid and dietary restrictions to identify gaps in published adherence interventions, searching PubMed, CINAHL, PsychInfo, Embase, and Web of Science databases. We analyzed qualitative data with a priori codes derived from the World Health Organization's adherence framework and subsequent codes from thematic analysis. RESULTS: We screened 1775 articles and extracted qualitative data from 12. The qualitative data revealed 20 factors unique to hemodialysis across the World Health Organization's five dimensions of adherence. In addition, two overarching themes emerged from the data: (1) adherence in the context of patients' whole lives and (2) dialysis treatment as a double-edged sword. Patient-level factors reflected in the qualitative data extended beyond knowledge about hemodialysis treatment or motivation to adhere to treatment. Patients described a profound grieving process over the loss of their "old self" that impacted adherence. They also navigated complex challenges that could be exacerbated by social determinants of health as they balanced treatment, life tasks, and social roles. CONCLUSIONS: This review adds to the growing evidence that one-size-fits-all approaches to improving adherence among patients on hemodialysis are inadequate. Adherence may improve when routine care incorporates patient context and provides ongoing support to patients and families as they navigate the logistical, physical, and psychological hardships of living with dialysis. New research is urgently needed to guide a change in course.

RESUMO

BACKGROUND: The burden and presentation of post-acute sequela of SARS-CoV-2 infection (PASC) are a developing major public health concern. OBJECTIVES: To characterize the burden of PASC in community-dwelling individuals and understand the experiences of people living with PASC. METHODS: This mixed-methods study of COVID-19 positive community-dwelling persons involved surveys and in-depth interviews. Main outcome was self-report of possible PASC symptoms 3 weeks or longer after positive COVID-19 test. In-depth interviews were guided by a semi-structured interview guide with open-ended questions and probes based on emerging literature on PASC and the impact of COVID-19. RESULTS: With a survey response rate of 70%, 442 participants were included in this analysis, mean (SD) age 45.4 (16.2) years, 71% female, 12% Black/African American. Compared to those with no PASC symptoms, persons who reported PASC symptoms were more likely to be older (mean age: 46.5 vs. 42; p = 0.013), female (74.3% vs. 61.2%; p = 0.010), to have pre-existing conditions (49.6% vs. 34%; p = 0.005), and to have been hospitalized for COVID-19 (14.2% vs. 2.9%; p = 0.002). About 30% of the participants experienced severe fatigue; the proportion of persons reporting severe fatigue was 7-fold greater in those with PASC symptoms (Adjusted Prevalence Ratio [aPR] 6.73, 95%CI: 2.80-16.18). Persons with PASC symptoms were more likely to report poor quality of life (16% vs. 5%, p<0.001) and worse mental health functioning (Mean difference: -1.87 95%CI: -2.38, -1.37, p<0.001). Themes from in-depth interviews revealed PASC was experienced as debilitating. CONCLUSIONS: In this study, the prevalence of PASC among community-dwelling adults was substantial. Participants reported considerable coping difficulties, restrictions in everyday activities, invisibility of symptoms and experiences, and impediments to getting and receiving PASC care.

RESUMO

ABSTRACT: Men who have sex with men (MSM) and people with HIV (PWH) perceive, internalize, and experience significant stigma from family members, health care providers, and community members because of their sexual behaviors. The current monkeypox (MPX) outbreak is affecting both communities. The pandemic has spread to 89 countries with more than 31,000 confirmed cases, and global agencies are concerned about how the disease is portrayed in the media. This article will introduce MPX and its associated stigmas, providing a brief theoretical perspective on adaptive behaviors and nursing interventions to mitigate stigma. This is followed by a case-based description of the current experiences of an MSM with MPX. We will discuss stigma prevention strategies from an adaptation and mitigation perspective. We conclude with how nurses can contribute to stigma prevention for individuals with MPX.

RESUMO

OBJECTIVES: (1) Summarise and evaluate the current evidence of tuberculosis (TB)-associated pregnancy outcomes, (2) evaluate the state of the science of family planning during TB treatment and (3) provide recommendations to move forward to improve care and outcomes during TB disease. DESIGN: Systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. DATA SOURCES: PubMed, Embase, CINAHL, Cochrane, Web of Science and Scopus were searched from September 2009 to November 2021. ELIGIBILITY CRITERIA: Studies were included if they assessed pregnant women with active TB, drug-resistant TB (DR-TB) or TB/HIV coinfection and examined pregnancy, maternal, fetal/birth and TB or TB/HIV coinfection outcomes. Studies were also included if they examined family planning services among women initiating TB treatment. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data using PRISMA guidelines and conducted quality assessment using the Joanna-Briggs Institute Critical Appraisal Tools. The level of evidence was reported using the Johns Hopkins Evidence-Based Practice guidelines. RESULTS: 69 studies were included in this review. Case reports, case series, case controls, cohort studies, secondary data analyses and a service delivery improvement project conducted in 26 countries made up the totality of the evidence. Most studies reported pregnancy complications for mothers (anaemia, postpartum haemorrhage, deaths) and fetuses or newborns (low birth weight, premature birth, and spontaneous or induced abortions). Few studies discussed the value of offering family planning to prevent adverse pregnancy outcomes. One study examined the effect of a provider training on contraceptive use with reported increased contraceptive use. CONCLUSIONS: Integrating family planning services within a TB treatment programme is essential to reduce adverse TB-associated maternal-child outcomes. Despite well-established adverse pregnancy outcomes, little attention has been paid to family planning to prevent poor pregnancy outcomes for women with TB/DR-TB. Recommendations for clinicians, TB programmes and researchers are provided and reflect evidence presented in this review.

RESUMO

ABSTRACT: Monkeypox is a zoonotic infection that manifests as dermatologic lesions that may be painful or pruritic and can appear on the face, trunk, extremities, genitals, and mucosal surfaces. In 2022, cases of monkeypox increased exponentially and it was declared a public health emergency by the World Health Organization and the U.S. Department of Health and Human Services. Unlike previous monkeypox outbreaks, the current situation has disproportionately affected men who have sex with men and seems to be associated with lower mortality. Options for treatment and prevention are limited. The distribution and availability of vaccines and antivirals has posed challenges for patients, clinicians, and public health systems. Early recognition and management of persons with monkeypox is critical in controlling the spread of this infection. This article reviews key features of monkeypox and highlights current recommendations for clinical management, prevention, and considerations for persons with HIV. Implications for public health and nursing are discussed.

RESUMO

This study combines theory and experiment in an examination of Co-C bonding and reductive Co-C cleavage in cobalt dichlorovinyl complexes. It is motivated by the role of dichlorovinyl complexes as intermediates in the dechlorination of trichloroethylene by cobalamin and cobalamin model complexes. A series of seven cis-1,2-dichlorovinyl(L)cobaloxime complexes were prepared (L = m- and p-substituted pyridines; cobaloxime = bis(dimethylglyoximato)cobalt). The complexes were characterized using 1H NMR, 13C NMR, cyclic voltammetry, and X-ray crystallography. Examination of the metrical parameters of the Co-C=C unit across the series shows very little change in the C=C bond length and a slight increase in the Co-C bond length with increasing electron-donating ability of the pyridine ligand. These structural changes along with electronic structure calculations indicate that Co-C pi-bonding is not important in these complexes. The stronger Co-C bonds of vinylcobaloximes compared to those of alkylcobaloximes are best explained by the higher s character at C. Changes in the reduction potential across the series indicate that the pyridine-bound form is the primary electrochemically active species. Theoretical examination of the Co-C cleavage following reduction supports the direct formation of the cis-1,2-dichlorovinyl anion and not the cis-1,2-dichlorovinyl radical.
