Pulmonary Arterial Hypertension (PAH) is overrepresented in People Living with Human Immunodeficiency Virus (PLWH). HIV protein gp120 plays a key role in the pathogenesis of HIV-PAH. Genetic changes in HIV gp120 determine viral interactions with chemokine receptors; specifically, HIV-X4 viruses interact with CXCR4 while HIV-R5 interact with CCR5 co-receptors. Herein, we leveraged banked samples from patients enrolled in the NIH Lung HIV studies and used bioinformatic analyses to investigate whether signature sequences in HIV-gp120 that predict tropism also predict PAH. Further biological assays were conducted in pulmonary endothelial cells in vitro and in HIV-transgenic rats. We found that significantly more persons living with HIV-PAH harbor HIV-X4 variants. Multiple HIV models showed that recombinant gp120-X4 as well as infectious HIV-X4 remarkably increase arachidonate 5-lipoxygenase (ALOX5) expression. ALOX5 is essential for the production of leukotrienes; we confirmed that leukotriene levels are increased in bronchoalveolar lavage fluid of HIV-infected patients. This is the first report associating HIV-gp120 genotype to a pulmonary disease phenotype, as we uncovered X4 viruses as potential agents in the pathophysiology of HIV-PAH. Altogether, our results allude to the supplementation of antiretroviral therapy with ALOX5 antagonists to rescue patients with HIV-X4 variants from fatal PAH.

Background: Caring for patients after a neurovascular incident is common for advanced practice registered nurses (APRNs). Most neurological readmission studies focus on a small subset of neurovascular incident groups, but advanced practice nurses in primary care attend to a diverse neurovascular population and lack time to adequately search hospital records. Purpose: The aim of this study was to determine readmission risk factors after a neurovascular incident to guide APRNs in the primary care setting. Methodology: The study is a retrospective observational study that used a crude single predictor model to determine potential risks for readmission. Results: A total of 876 neurovascular participants were studied. Of these, only 317 experienced at least one hospital readmission, with 703 readmissions within 1 year, indicating some were readmitted more than once. Risks for readmission varied across neurovascular events. The main reasons for readmission were because of neurological, cardiovascular, and musculoskeletal complications. Conclusions: Stroke readmission rates are high and require intervention by APRNs. To prevent readmission includes timely follow-up within 30 days and should also include longitudinal follow-up beyond 90 days to prevent hospital readmission. Implications: Future studies are needed to create guidelines for APRNs that implement rehabilitation strategies to decrease hospital readmission for the neurovascular population that focus on interdisciplinary communication.

Objective To pilot test an infographic-based health communication intervention that our team rigorously designed and explore whether its implementation leads to better health outcomes among Latino persons with HIV (PWH). Materials and Methods Latino PWH (N  = 30) living in New York City received the intervention during health education sessions at 3 study visits that occurred approximately 3 months apart. At each visit, participants completed baseline or follow-up assessments and laboratory data were extracted from patient charts. We assessed 6 outcomes (HIV-related knowledge, self-efficacy to manage HIV, adherence to antiretroviral therapy, CD4 count, viral load, and current and overall health status) selected according to a conceptual model that describes pathways through which communication influences health outcomes. We assessed changes in outcomes over time using quantile and generalized linear regression models controlling for the coronavirus disease 2019 (COVID-19) research pause and new patient status (new/established) at the time of enrollment. Results Most participants were male (60%) and Spanish-speaking (60%); 40% of participants identified as Mixed Race/Mestizo, 13.3% as Black, 13.3% as White, and 33.3% as "other" race. Outcome measures generally improved after the second intervention exposure. Following the third intervention exposure (after the COVID-19 research pause), only the improvements in HIV-related knowledge and current health status were statistically significant. Discussion and Conclusion Our infographic-based health communication intervention may lead to better health outcomes among Latino PWH, but larger trials are needed to establish efficacy. From this work, we contribute suggestions for effective infographic use for patient-provider communication to enhance patient education in clinical settings. [ABSTRACT FROM AUTHOR]

Movements designed to engage youth in tobacco control have been an important part of tobacco prevention for decades. Today, young people are increasingly diverse, and their primary issues of concern are gun control, racism, mental health, and climate change. To engage today's young people, tobacco control programs need to draw connections between youth's identities, top issues, and tobacco. UpRISE is a social justice youth tobacco control movement that engages diverse youth in identifying the root causes of youth nicotine use. In 2018–2019, 21 youth-serving organizations and schools hosted youth coalitions. Coalitions engaged in a six-session workbook called "Getting to the root cause," and adults were provided training and reflective supervision. Pre/post surveys with youth participants (n = 180) and end-of-year interviews with adult facilitators (n = 22) were used to assess outcomes. The primary outcomes were supportive adult relationships, youth voice in decision-making, anti-tobacco industry attitudes and beliefs, psychological empowerment, critical consciousness, and global belief in a just world. Quantitative measures of supportive adult relationships, youth voice in decision-making, psychological empowerment, and anti-tobacco industry attitudes and beliefs all increased significantly over time (p <.0001, p <.0001, p <.0001, p =.0034, respectively). Critical consciousness and global belief in a just world did not change significantly. During interviews, adults reported learning how: to engage in youth–adult partnerships, the tobacco industry abused its power, to engage in critical reflection about power. Adults also felt empowered. UpRISE may be a promising approach to increase racially diverse youth's engagement in social justice-oriented tobacco control efforts that advance equity.

Objective Human milk (HM) insulin plays many roles for the infant, especially for the newborn. We hypothesized HM insulin in women with type 2 diabetes (T2DM) would be higher than BMI-matched women with either gestational diabetes (GDM) or normal glucose tolerance (NGT). In T2DM, we also assessed macronutrient composition and relationships between maternal glycemic control and HM insulin. Study design HM was characterized at 2-weeks postpartum among three BMI-matched groups: T2DM (n= 12), diet-controlled GDM (n= 12), and NGT (n= 12). In T2DM, additional fasting and postprandial HM samples were collected while wearing a continuous glucose monitor (CGM), as well as fasting and 90-minute postprandial samples after a standardized meal at 1–2 weeks postpartum. Results Fasting HM insulin was two times higher in T2DM compared to GDM and NGT (p < .001), which were not different from each other. Among T2DM, fasting (p < .001) and postprandial (p = .01) HM insulin levels were between 2 and 5× higher than plasma. Postprandial HM insulin (p = .03) and glucose (p < .001) were increased compared to fasting. Mean nocturnal glucose (p < .01) and maternal hemoglobin A1c (p < .01) positively associated with fasting HM insulin. Conclusions These data are the first to show HM insulin concentrations are doubled in T2DM compared to BMI-matched GDM and NGT. In HM of T2DM, insulin increases postprandially, may be concentrated relative to plasma, and is influenced by maternal glycemic control, with potential clinical implications that merit further study.

Supplemental Digital Content is Available in the Text. Background: Over the past 20 years, significant evidence has emerged for collaborative care in the treatment of depression and anxiety disorders in primary care. Purpose: The purpose of this project was to integrate an interprofessional and collaborative care model of behavioral health services into routine nurse-led primary care delivered to vulnerable and underserved populations across the lifespan. Team members included psychiatric nurse practitioners (PMHNPs), a registered nurse, and a case manager. Methods: An Access database was developed to track clients seen by the PMHNPs. Three key outcome measures were tracked over time: Posttraumatic Stress Disorder (PTSD) Checklist Civilian Version, Hamilton Depression Rating Scale (HAM-D), and Bipolar Depression Rating Scale (BDRS). A retrospective analysis of client outcome data from January 2017 through December 2019 was conducted. Results: There were 118 patients included who were mostly female (63.6%), White (90.7%), and not Hispanic (69.5%), with Medicaid as their primary insurance (74.6%). For each outcome, models with linear and quadratic function forms for time were fit. The final model for PTSD Checklist Score had a linear functional form for time and the final models for BDRS and HAM-D had linear and quadratic terms for time. All predictors were significantly associated with the outcome. Implications for practice: This program demonstrated that a patient-centered, nurse-led team approach to the treatment of depression, bipolar depression, and PTSD can be successful in primary care.

Background Hospitalised patients whose inpatient teams rotate off service experience increased mortality related to end-of-rotation care transitions, yet standardised handoff practices are lacking. Objective Develop and implement a multidisciplinary patient-centred handoff intervention to improve outcomes for patients who are critically ill during end-of-rotation transitions. Design, setting and participants Single-centre, controlled pilot study of medical intensive care unit (ICU) patients whose resident team was undergoing end-of-rotation transition at a university hospital from June 2017 to February 2018. Intervention A 4-item intervention was implemented over two study periods. Intervention 1 included: (1) in-person bedside handoff between teams rotating off and on service, (2) handoff checklist, (3) nursing involvement in handoff, and (4) 30 min education session. Intervention 2 included the additional option to conduct bedside handoff via videoconferencing. Main outcome measures Implementation was measured by repeated clinician surveys and direct observation. Patient outcomes included length of stay (LOS; ICU and hospital) and mortality (ICU, hospital and 30 days). Clinician perceptions were modelled over time using per cent positive responses in logistic regression. Patient outcomes were compared with matched control 'transition' patients from 1 year prior to implementation of the intervention. Results Among 270 transition patients, 46.3% were female with a mean age of 55.9 years. Mechanical ventilation (64.1%) and in-hospital death (27.6%) rates were prevalent. Despite high implementation rates--handoff participation (93.8%), checklist utilisation (75.0%), videoconferencing (62.5%), nursing involvement (75.0%)--the intervention did not significantly improve LOS or mortality. Multidisciplinary survey data revealed significant improvement in acceptability by nursing staff, while satisfaction significantly declined for resident physicians. Conclusions In this controlled pilot study, a structured ICU end-of-rotation care transition strategy was feasible to implement with high fidelity. While mortality and LOS were not affected in a pilot study with limited power, the pragmatic strategy of this intervention holds promise for future trials. [ABSTRACT FROM AUTHOR]

Objective: To evaluate patterns of elevations of isotypes of rheumatoid factor (RF) and anti–citrullinated protein antibodies (ACPAs) pre–rheumatoid arthritis (RA) diagnosis and post–RA diagnosis. Methods: Using the Department of Defense Serum Repository we identified 214 RA cases and 210 matched controls. Up to 3 pre–RA diagnosis and 1 post–RA diagnosis serum samples per subject were tested for RF and for IgA, IgG, and IgM ACPAs. The timing and trajectories of elevations of autoantibodies were evaluated. Results: Autoantibody levels were elevated in cases versus controls a mean of 17.9 years before RA diagnosis for IgG ACPA, 14.2 years for IgA‐RF, 7.2 years for IgM‐RF, 6.2 years for IgA ACPA, and 5.0 years for both IgM ACPA and IgG‐RF (P < 0.01 for all comparisons). There were similar relationships for positive or negative autoantibody status, with cases first showing positivity for IgG ACPA 1.9 years pre‐RA and for IgA‐RF 1.7 years pre‐RA, followed by the other isotypes. Only IgA ACPA positivity was significantly increased in post–RA diagnosis samples (19% 0–2 years pre‐RA versus 39% >2 years post–RA diagnosis; P = 0.04). All autoantibody levels demonstrated an early initial elevation, a period of stability, then an increase immediately before RA diagnosis. A pre‐RA endotype of early elevation of autoantibodies was associated with increased use of biologic therapy, and a higher prevalence of sicca symptoms and lung disease post–RA diagnosis. Conclusion: Differences in patterns of elevations of autoantibody isotypes have implications for understanding the pathophysiology of RA development. These include understanding what factors drive initial autoantibody elevations compared to what factors (including mucosal) drive later increases in autoantibody levels and a transition to clinically apparent RA, and how pre‐RA endotypes may influence post–RA diagnosis phenotypes.
