OBJECTIVE: Explore participants' perceptions of urban gardens and peer nutritional counseling intervention for people with HIV and food insecurity on antiretroviral therapy in the Dominican Republic. METHODS: Semistructured endline interviews (n = 21) with intervention participants about their perceptions of diet, health, and quality of life. A codebook was applied to verbatim transcripts, and coded data were analyzed using matrices to identify themes. RESULTS: Participants were mostly Dominican (86%; 14% Haitian); 57% were men; the mean age was 45 years...

BACKGROUND: Health inequalities in African American communities have been further exacerbated by COVID-19. Public health departments and other safety-net providers across the United States have partnered with community-based organizations to address barriers to COVID-19 testing in disproportionately impacted communities. This narrative review summarizes lessons learned from published examples of these community-based COVID-19 testing efforts. METHODS: We searched online databases for peer-reviewed articles on community-based COVID-19 testing interventions in the United States aimed at increasing COVID-19 testing among African American populations...

It is well established that oxaliplatin, one of the three Pt(II) anticancer drugs approved worldwide, and phenanthriplatin, an important preclinical monofunctional Pt(II) anticancer drug, possess a different mode of action from that of cisplatin and carboplatin, namely, the induction of nucleolar stress. The exact mechanisms that lead to Pt-induced nucleolar stress are, however, still poorly understood. As such, studies aimed at better understanding the biological targets of both oxaliplatin and phenanthriplatin are urgently needed to expand our understanding of Pt-induced nucleolar stress and guide the future design of Pt chemotherapeutics...

This study investigated community empowerment as a means of addressing food insecurity amongst underserved neighborhoods by increasing available and affordable food choices through Clementine Collective stands in Staten Island, New York (Richmond County), one of the 5 Boroughs of New York City. Given the growing complexity of food insecurity, inclusive and equitable action must be taken that incorporates the voices, perspectives and needs of those most impacted. Through methods of community engagement and empowerment, the Clementine Collective collaborates with local community residents to introduce sustainable solutions that address food insecurity...

BACKGROUND: Faith-based interventions are promising for promoting healthy behaviors among adults, but their ripple effects on participants' children are unknown. This study is one of the first to assess the effects of a faith-based multilevel obesity intervention on adult participants' children. METHODS: We analyzed quantitative data from a cluster randomized controlled trial with two African American and two Latino churches in South Los Angeles, California, which invited adult participants to enroll one child (5-17 years) in a sub-study...

In the context of a couples cohort established to evaluate an optimised couples-focused behavioural intervention in rural South Africa, we examined: (1) Is couples' relationship quality (RQ) associated with couples HIV testing and counselling (CHTC) uptake? (2) Does CHTC uptake or the intervention components uptake improve subsequent RQ? Enrolled couples, ( n  = 218), previously naïve to couples HIV testing, were invited to two group sessions and offered four couples counselling sessions (CS1-CS4), as part of the intervention and administered a questionnaire individually at baseline, four weeks, and four months, which included item-scales to measure RQ: satisfaction, intimacy, dyadic trust, conflict, and mutual constructive communication...

Latinos have high rates of type 2 diabetes mellitus (T2DM) yet are characterized as having health-promoting social networks. The impacts of COVID-19 on personal networks were complex, especially in urban areas with high proportion of immigrants such as the Bronx in NYC. Our objective was to test the extent to which network characteristics increase vulnerability or resiliency for glycemic control based on data gathered from Mexican-origin Bronx dwellers. We used two-wave panel study analyzing self-reported personal social networks (n=30participants ; 600network members ) and HbA1c levels via dried blood spots in 2019, before the COVID-19 pandemic, and in 2021, a time after initial lockdowns and when the pandemic was still ravaging the community of study...

BACKGROUND: Immune-related adverse events (irAEs) are major barriers of clinical management and further development of immune checkpoint inhibitors (ICIs) for cancer therapy. Therefore, biomarkers associated with the onset of severe irAEs are needed. In this study, we aimed to identify immune features detectable in peripheral blood and associated with the development of severe irAEs that required clinical intervention. METHODS: We used a 43-marker mass cytometry panel to characterize peripheral blood mononuclear cells from 28 unique patients with melanoma across 29 lines of ICI therapy before treatment (baseline), before the onset of irAEs (pre-irAE) and at the peak of irAEs (irAE-max)...

Since response to antigen-based immunotherapy relies upon the level of tumor antigen expression we developed an antigen quantification assay using ABC values. Antigen quantification as a clinical assay requires methods for quality control and for interlaboratory and inter-cytometer platform standardization. A single lot of Cytotrol™ Lyophilized Control Cells (Beckman Coulter) used for all studies. The variability in antigen quantification across 4 different instrument platforms in 2 separate laboratories was evaluated...

BACKGROUND: Diabetic patients are at increased risk of acute kidney injury (AKI) following surgery. The significance of uncontrolled diabetes on kidney function after coronary artery bypass grafting (CABG) remains controversial. Our aim was to study the association between pre-operative hemoglobin A1c (HbA1c) and severe cardiac surgery-associated AKI (CSA-AKI) following CABG. METHODS: A single-center, retrospective cohort study including patients who underwent isolated CABG from 2010 to 2018 was performed...

Formation of active HIV-1 reverse transcriptase (RT) proceeds via a structural maturation process that involves subdomain rearrangements and formation of an asymmetric p66/p66' homodimer. These studies were undertaken to evaluate whether the information about this maturation process can be used to identify small molecule ligands that retard or interfere with the steps involved. We utilized the isolated polymerase domain, p51, rather than p66, since the initial subdomain rearrangements are largely limited to this domain...

INTRODUCTION: To examine risk factors for new-onset postoperative atrial fibrillation (POAF) after cardiac surgery. METHODS: Patients enrolled in the Cardiothoracic Surgical Trials Network multicenter, randomized trial of rate control versus rhythm control for POAF were included. Predictors of POAF were determined using multivariable logistic regression. RESULTS: Among the 2104 patients who were enrolled preoperatively, 695 developed POAF (33...

Primrose syndrome is a rare autosomal dominant disorder that is characterized by recognizable facial phenotype, sensorineural hearing loss, hypotonia, and developmental delay. All reported probands show de novo ZBTB20 pathogenic variant. Since its discovery in 1982, Primrose syndrome has remained an underdiagnosed condition. Awareness of presentation and prompt diagnostic workup are crucial for early identification and proper management. In this case report, we discuss a case of Primrose syndrome diagnosed in an infant born at Wellspan Hospital in York, PA...

OBJECTIVE: Food security interventions with people living with HIV (PLHIV) are needed to improve HIV outcomes. This process evaluation of a pilot intervention involving urban gardening and peer nutritional counselling with PLHIV assesses feasibility, acceptability and implementation challenges to inform scale-up. DESIGN: Mixed methods were used, including quantitative data on intervention participation and feasibility and acceptability among participants ( n 45) and qualitative data from a purposive sample of participants ( n 21)...

Pt(ii) chemotherapeutic complexes have been used as predominant anticancer drugs for nearly fifty years. Currently there are three FDA-approved chemotherapeutic Pt(ii) complexes: cisplatin, carboplatin, and oxaliplatin. Until recently, it was believed that all three complexes induced cellular apoptosis through the DNA damage response pathway. Studies within the last decade, however, suggest that oxaliplatin may instead induce cell death through a unique nucleolar stress pathway. Pt(ii)-induced nucleolar stress is not well understood and further investigation of this pathway may provide both basic knowledge about nucleolar stress as well as insight for more tunable Pt(ii) chemotherapeutics...

PURPOSE/OBJECTIVE(S): Patients treated with Tumor Treating Fields (TTFields) therapy for glioblastoma (GBM) have array layouts planned by NovoTAL. NovoTAL requires morphometric inputs and maximizes field intensity at the tumor. Patient-specific segmentation-based treatment planning (SBTP) software uses segmentation-based plans to maximize power density at defined regions of interest (ROIs). This technical analysis compared expected local minimum power density (LMiPD; mW/cm3) and local minimum field intensity (LMiFI; V/cm) delivered to ROIs with array layouts planned with SBTP vs NovoTAL...

HIV-related stigma can affect health by compromising coping and social support. Gender differences in stigma experiences and social support are underexplored, particularly in the Caribbean. We conducted semi-structured interviews (N = 32) with patients at two HIV clinics in the Dominican Republic. Transcripts were coded using qualitative content analysis (deductive and inductive approaches) to identify themes regarding stigma experiences and social support, which were then compared across men and women participants to identify gender differences...

Vincamine is a naturally occurring indole alkaloid showing antioxidant activity and has been used clinically for the prevention and treatment of cerebrovascular disorders and insufficiencies. It has been well documented that antioxidants may contribute to cancer treatment, and thus, vincamine has been investigated recently for its potential antitumor activity. Vincamine was found to show cancer cell cytotoxicity and to modulate several important proteins involved in tumor growth, including acetylcholinesterase (AChE), mitogen-activated protein kinase (MAPK), nuclear factor-κB (NF-κB), nuclear factor erythroid 2-related factor 2 (Nrf2), and T-box 3 (TBX3)...

We present a laser system for performing single-photon atom interferometry on the 698 nm clock transition in ultracold strontium. We coherently combine the power of two titanium:sapphire lasers and demonstrate chirps of 200 MHz in 2.5 ms while phase-locked to an optical reference. Moreover, we demonstrate a novel, to the best of our knowledge, scheme to deliver 4 W pulsed beams to the atoms via a mode-cleaning optical fiber using active noise cancellation.
