RESUMEN

BACKGROUND: Over the last two centuries nurses have been practicing, teaching, and conducting research on social factors that contribute to health and the language has evolved over this time. PURPOSE: To explore how social factors that contribute to health are described by nurse authors and how that use has changed over time. METHODS: A scoping review using the JBI Manual for Evidence Synthesis, Cochrane Handbook, and PRISMA guidelines was completed. FINDINGS: From 1967 to 2021, nurses used the term "social factors" most commonly and there was a shift from demographic to social factors. DISCUSSION: As the language that nurses use has shifted from demographic descriptions to the social factors that may be associated with those descriptions, nurses have an opportunity to promote the use of non-deterministic language for health promotion and research.

RESUMEN

BACKGROUND: Women living with HIV (WLWH) report low engagement in health care, missed office visits, and less engagement in the clinical encounter. Strengthening the clinical encounter for WLWH may improve health outcomes and quality of life. The Adaptive Leadership Framework for Chronic Illness offers specific adaptive leadership strategies for providers to improve patient-provider interactions. The purpose of this study was to examine adaptive leadership behaviors that contribute to the development of effective patient-provider communication from the perspectives of WLWH. METHODS: The descriptive, cross-sectional and qualitative study conducted interviews with 22 WLWH to assess perceptions of the clinical encounter related to HIV-related stigma, engagement in care, medical distrust, and experiences with discrimination and quality of life. Members of the study team using a set of a priori codes analyzed data using NVivo 12.0. RESULTS: Participants described two primary themes and subthemes of each for adaptive leadership behaviors. The primary theme for adaptive leadership of providers was "my provider cares about me"; subthemes were communication, trust building takes time, and supportive providers are trusted. The primary theme for adaptive leadership of WLWH themselves was "I care about me; subthemes were self-advocacy and self-empowerment. CONCLUSIONS: Providers can use adaptive leadership behaviors during clinical encounters to support WLWH, improve patient-provider communication, enhance trust, and improve patient outcomes.

RESUMEN

BACKGROUND: Few studies have examined long-term outcomes among persons who initiate preexposure prophylaxis (PrEP) in the South, including PrEP discontinuation and sexually transmitted infection (STI) rates. METHODS: Care discontinuation (>6 months without a PrEP appointment) and incident STIs were evaluated for patients at 2 PrEP clinics in Durham, NC. We tested for predictors of discontinuation as a binary variable using logistic regression. Model covariates included age, race/ethnicity, sex, known HIV-positive partner, commercial sex work, men who have sex with men (MSM) versus not MSM, type of insurance, and clinic site. A similar analysis was completed for STI incidence, controlling for days in the study. RESULTS: Among 271 patients, mean age was 33.2 years, 46.9% were Black and 11.1% were Latino, 81.2% were MSM, and 32% were uninsured. Preexposure prophylaxis was discontinued in 47%, and another 11% had intermittent care. Sexually transmitted infection incidence was 45.4/100 person-years, and 5 patients were diagnosed with HIV at baseline or in follow-up. Men who have sex with men were less likely to discontinue PrEP relative to non-MSM (odds ratio [OR], 0.26; 95% confidence interval [CI], 0.10-0.64). Baseline STI was associated with a higher likelihood of incident STI (OR, 8.19; 95% CI, 3.69-19.21), whereas care discontinuation was associated with a lower likelihood of STI (OR, 0.28; 95% CI, 0.11-0.65). CONCLUSIONS: Preexposure prophylaxis programs in the Southern United States are reaching uninsured and predominantly Black and Latino MSM, but discontinuation rates are high despite elevated rates of incident STI and HIV. Further work is required to elucidate causes of PrEP discontinuation and encourage persistence in care.

RESUMEN

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, but many primary care physicians (PCPs) have not incorporated PrEP into practice. While PrEP may be a key strategy to reducing high HIV transmission rates in the southern US, knowledge about PrEP prescribing patterns among PCPs in this region is lacking. An online survey was sent to a large network of PCPs at an academic medical center in North Carolina in October 2015. The survey was repeated in September 2016, after an educational intervention that included on-site trainings at 14 PCP offices. Chi-square tests were used to compare PrEP prescribing patterns among providers. The initial survey was sent to 389 PCPs, with 115 (30%) responding. Of these, 78% reported seeing men who have sex with men (MSM). Only 17% had prescribed PrEP. The most frequently identified barrier was lack of knowledge (60%). When the survey was repeated after the educational initiative, 79 PCPs (20%) responded. Of these, 90% reported seeing MSM, and 35% had prescribed PrEP. PCPs who had attended a training were more likely to have prescribed PrEP (OR 4.84, CI 1.77-13.21). In conclusion, PrEP prescribing among PCPs in the southern US is low. A survey among PCPs identified lack of knowledge as a barrier to prescribing, motivating an institutional-wide educational campaign in response. Further efforts are needed to continue to raise awareness and educate PCPs in the South about PrEP.

RESUMEN

BACKGROUND AIMS: Umbilical cord blood (CB) is being used as a source of hematopoietic stem cells (HSCs) and immune cells to treat many disorders. Because these cells are present in low numbers in CB, investigators have developed strategies to expand HSCs and other immune cells such as natural killer (NK) cells. The initial step in this process is to enrich mononuclear cells (MNCs) while depleting unwanted cells. The manual method of MNC enrichment is routinely used by many centers; however, it is an open system, time-consuming and operator dependent. For clinical manufacturing, it is important to have a closed system to avoid microbial contamination. METHODS: In this study, we optimized an automated, closed system (Sepax) for enriching MNCs from cryopreserved CB units. RESULTS: Using Sepax, we observed higher recovery of total nucleated cells (TNC), CD34+ cells, NK cells and monocytes when compared to manual enrichment, despite similar TNC and CD34+ viability with the two methods. Even though the depletion of red blood cells, granulocytes and platelets was superior using the manual method, significantly higher CFU-GM were obtained in MNCs enriched using Sepax compared to the manual method. This is likely related to the fact that the automated Sepax significantly shortened the processing time (Sepax: 74 - 175 minutes versus manual method: 180 - 290 minutes). The use of DNAse and MgCl2 during the Sepax thaw and wash procedure prevents clumping of cells and loss of viability, resulting in improved post-thaw cell recovery. DISCUSSION: We optimized enrichment of MNCs from cryopreserved CB products in a closed system using the Sepax which is a walk away and automated processing system.

RESUMEN

BACKGROUND: Sexually transmitted infection (STI) diagnosis after diagnosis of acute HIV infection (AHI) indicates ongoing high-risk sexual behavior and possible risk of HIV transmission. We assessed predictors of STI acquisition and the effect of time since care entry on STI incidence in patients with AHI in care and receiving consistent risk-reduction messaging. METHODS: Data on incident gonorrhea, chlamydia, trichomoniasis, primary/secondary syphilis, demographic, and clinical risk factors were abstracted from medical charts for patients diagnosed as having AHI and engaged in care. Poisson regression models using generalized estimating equations were fit to estimate incidence rates (IRs), IR ratios, and robust 95% confidence intervals. RESULTS: Among 185 patients with AHI, 26 (14%) were diagnosed as having at least 1 incident STI over 709.4 person-years; 46 STIs were diagnosed during follow-up (IR, 6.8/100 person-years). The median time from HIV care entry to first STI diagnosis was 609 days (range, 168-1681 days). Men who have sex with men (P = 0.03), a shorter time between presentation to medical care and AHI diagnosis (P = 0.06), and STI diagnosis before AHI diagnosis (P = 0.0003) were predictors of incident STI. Sexually transmitted infection IR greater than 1 year after entering care was double that of patients in care 1 year or less (IR ratio, 2.0; 95% confidence interval, 0.8-4.9). HIV viral load was above the limits of detection within 1 month of 11 STI diagnoses in 6 patients (23.1%) (median, 15,898 copies/mL; range, 244-152,000 copies/mL). CONCLUSIONS: Despite regular HIV care, STI incidence was high among this primarily young, men who have sex with men AHI cohort. Early antiretroviral initiation may decrease HIV transmission given ongoing risk behaviors despite risk-reduction messaging.

RESUMEN

Previous studies have revealed that HIV-infected individuals possess circulating CD4(+)CD8(+) double-positive (DP) T cells specific for HIV Ags. In the present study, we analyzed the proliferation and functional profile of circulating DP T cells from 30 acutely HIV-infected individuals and 10 chronically HIV-infected viral controllers. The acutely infected group had DP T cells that showed more proliferative capability and multifunctionality than did both their CD4(+) and CD8(+) T cells. DP T cells were found to exhibit greater proliferation and higher multifunctionality compared with CD4 T cells in the viral controller group. The DP T cell response represented 16% of the total anti-HIV proliferative response and >70% of the anti-HIV multifunctional response in the acutely infected subjects. Proliferating DP T cells of the acutely infected subjects responded to all HIV Ag pools with equal magnitude. Conversely, the multifunctional response was focused on the pool representing Nef, Rev, Tat, VPR, and VPU. Meanwhile, the controllers' DP T cells focused on Gag and the Nef, Rev, Tat, VPR, and VPU pool for both their proliferative and multifunctional responses. Finally, we show that the presence of proliferating DP T cells following all HIV Ag stimulations is well correlated with proliferating CD4 T cells whereas multifunctionality appears to be largely independent of multifunctionality in other T cell compartments. Therefore, DP T cells represent a highly reactive cell population during acute HIV infection, which responds independently from the traditional T cell compartments.

RESUMEN

The US National HIV/AIDS Strategy (NHAS) is a comprehensive plan that outlines specific goals for Ending the HIV Epidemic in the United States (EHE) by 2025. The strategy also provides specific strategies to prevent new HIV infections and improve health outcomes for people with HIV. The EHE is a companion document which focuses on achieving the goals of the NHAS in specific US jurisdictions where the HIV epidemic is concentrated. This article provides an overview of the NHAS and EHE and provides examples of programs and strategies that can be used to end the HIV epidemic in the United States.

RESUMEN

ABSTRACT: In the United States, Black cisgender women account for one in five new HIV infections with Black Americans, accounting for 57% of new diagnoses in the South. Pre-exposure prophylaxis (PrEP) is 99% effective at preventing HIV. Still, Black women's uptake remains at 2% due to multiple documented barriers, including lack of awareness and knowledge, mistrust, stigma, and low perceived risk. Culturally relevant interventions leveraging trusted venues, such as beauty salons, can overcome these barriers. This article reports preliminary results of an intervention to improve PrEP knowledge and awareness, PrEP stigma, PrEP trust, and uptake among Black cisgender women. This multilevel, mixed-methods study used a community-engagement approach to develop and pilot a salon-based intervention, Using PrEP and Doing it for Ourselves (UPDOs) Protective Styles. The intervention improved knowledge, awareness, and trust around PrEP among Black cisgender women. PrEP use stigma within interpersonal relationships decreased, but low perceived risk and social stigma remained constant. Culturally and socially acceptable interventions like UPDOs Protective Styles can model health care delivery to improve trust, thus improving uptake over time for this population.

RESUMEN

ABSTRACT: Stigma is a fundamental cause of health inequities. Guided by the Adaptive Leadership Framework for Chronic Illness (ALFCI), this descriptive qualitative study explored the challenges of stigma and disclosure experienced by women with HIV (WWH) in the Southern United States. A convenience sample of 22 WWH aged 36 to 62 years were interviewed for this study. Analysis of participant interviews revealed that WWH face a multitude of stigma-related technical and adaptive challenges, which are consistent with the ALFCI. Once identified, technical challenges, such as recognizing the need for support, lack of trust, and fear of rejection, can be overcome by technical work, including providing assistance with HIV disclosure and building a trusted network. By identifying specific adaptive and technical challenges faced by WWH and engaging in technical and adaptive work, the WWH and the provider can reduce the fear of disclosure and the effect of stigma.

RESUMEN

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.

RESUMEN

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.

RESUMEN

ABSTRACT: Women living with HIV have a higher burden of non-AIDS comorbidities and prevalence of chronic conditions. The Adaptive Leadership Framework for Chronic Illness clarifies living with complex health challenges by delineating the technical work of health care providers as well as the adaptive work and leadership behaviors of patients and their providers. We conducted a descriptive, qualitative study of women residing in the Southern United States who were participating in the Women's Interagency HIV Study in North Carolina. Twenty-two participants (mean age = 52.2 years; 90.9% self-identifying as Black or African American) completed semi-structured qualitative interviews. We identified adaptive challenges (e.g., affective and disclosure challenges) and adaptive work and leadership behaviors. Women learned skills to care for their health and support their families and to work with their providers to manage their care. Findings support the importance of identifying leadership behaviors for the purpose of developing person-centered interventions.

RESUMEN

ABSTRACT: Black women living with HIV (WLWH) face individual and sociostructural challenges. Despite these challenges, many exemplify remarkable levels of resilience and coping. Yet, research on resilience and coping in this population is limited. Twenty Black WLWH in the Southern United States completed semi-structured interviews that explored challenges facing WLWH. We identified six themes related to resilience and coping: self-acceptance, disclosure, self-compassion, social support, will to live, and service. Of these, social support was a driving protective element and an essential component to building and sustaining resilience and coping. Women who experienced positive support often expressed a will to live as well as a desire to support other WLWH. Resilience and social support were characterized by patterns of reciprocity, in that they were mutually sustaining, stabilizing, and strengthening.

RESUMEN

We report a case of substantial weight gain in a virologically suppressed patient with HIV after changing his antiretroviral therapy from efavirenz/emtricitabine/tenofovir DF to elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide with subsequent rapid weight loss upon switching back. The role of antiretrovirals in weight gain and loss and patient- and HIV-specific factors are discussed.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate penetration of antiretrovirals into compartments and efficacy of a dual, NRTI-sparing regimen in acute HIV infection (AHI). DESIGN: Single-arm, open-label pilot study of participants with AHI initiating ritonavir-boosted darunavir 800 mg once daily and etravirine 400 mg once daily or 200 mg twice daily within 30 days of AHI diagnosis. METHODS: Efficacy was defined as HIV RNA less than 200 copies/ml by week 24. Optional sub-studies included pharmacokinetics analysis from genital fluids (weeks 0-4, 12, 48), cerebrospinal fluid (CSF) (weeks 2-4, 24 and 48) and endoscopic biopsies (weeks 4-12 and 36-48). Neuropsychological performance was assessed at weeks 0, 24 and 48. RESULTS: Fifteen AHI participants were enrolled. Twelve (80%) participants achieved HIV RNA less than 200 copies/ml by week 24. Among 12 participants retained through week 48, nine (75%) remained suppressed to less than 50 copies/ml. The median time from ART initiation to suppression less than 200 and less than 50 copies/ml was 59 and 86 days, respectively. The penetration ratios for etravirine and darunavir in gut associated lymphoid tissue were 19.2 and 3.05, respectively. Most AHI participants achieving viral suppression experienced neurocognitive improvement. Of the three participants without overall improvement in neurocognitive functioning as measured by impairment ratings (more than two tests below 1 SD), two had virologic failure. CONCLUSION: NRTI-sparing ART started during AHI resulted in rapid viral suppression similar to NRTI-based regimens. More novel and compact two-drug treatments for AHI should be considered. Early institution of ART during AHI appears to improve overall neurocognitive function and may reduce the risk of subsequent neurocognitive impairment. CLINICALTRIALS.GOV:: NCT00855413.

RESUMEN

BACKGROUND: Transmitted drug resistance (TDR) limits antiretroviral options and thus complicates the management of HIV-positive patients. HIV disproportionately affects the southern US, but available national estimates of TDR prevalence principally reflect large metropolitan centres outside this region. METHODS: The Duke/UNC Acute HIV Program has collected data on acute or recent HIV infections (ARHI) in North Carolina since 1998. Acute infections represent antibody-negative, RNA-positive patients. Recent infection was determined by history of HIV testing or concordance between detuned ELISA and antibody avidity assays. Genotypic sequence data from the earliest collected pretreatment plasma samples were analysed with the Stanford HIV Database and screened for surveillance drug resistance mutations (SDRMs). RESULTS: A total of 253 individuals with ARHI between May 1998 and May 2007 had complete genotypic sequence data for analysis; 39.5% were acute infections, 78.7% were male, 64.8% were non-White and 53.8% were men who have sex with men. The overall prevalence of TDR was 17.8%, with SDRMs for non-nucleoside/nucleotide reverse transcriptase inhibitors (NNRTIs) in 9.5% of the cohort. Mutations for nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) were detected in 7.5% and for protease inhibitors (PIs) in 3.2%. K103N was the most common mutation (7.5%). Thymidine analogue mutations were found in 4.7% of samples; the most common PI SDRM was L90M (2.4%). Dual- or triple-class antiretroviral resistance was rare, encountered in only six (2.4%) samples. CONCLUSIONS: The prevalence of TDR in North Carolina is similar to estimates from the US metropolitan areas. These findings have implications for initial regimen selection and secondary prevention efforts outside of large, metropolitan HIV epicentres.
