Barcoding of viable peripheral blood mononuclear cells with selenium and tellurium isotopes for mass cytometry experiments.

Barcoding viable cells combined with pooled sample staining is an effective technique that eliminates batch effects from serial cell staining and facilitates uninterrupted data acquisition. We describe three novel and isotopically pure selenium-containing compounds (SeMals) that are useful cellular labeling tools. The maleimide-functionalized selenophenes (SeMal, SeMal, and SeMal) covalently react with cellular sulfhydryl groups and uniquely label cell samples.

The pace of change of summertime temperature extremes.

Summer temperature extremes can have large impacts on humans and the biosphere, and an increase in heat extremes is one of the most visible symptoms of climate change. Multiple mechanisms have been proposed that would predict faster warming of heat extremes than typical summer days, but it is unclear whether this is occurring. Here, we show that, in both observations and historical climate model simulations, the hottest summer days have warmed at the same pace as the median globally, in each hemisphere, and in the tropics from 1959 to 2023.

Barriers and facilitators to implementing evidence-based integrated HIV and behavioral health care: perspectives from seven federal ending the HIV epidemic jurisdictions.

The federal Ending the HIV Epidemic (EHE) initiative was created to reduce new US HIV infections, largely through pre-exposure prophylaxis and HIV treatments that reduce HIV transmissibility to zero. Behavioral health disorders (mental health and substance use) remain significant barriers to achieving EHE goals. Addressing behavioral health (BH) disorders within HIV primary care settings has been promoted as a critical EHE strategy.

Interventions for Integrating Behavioral Health into HIV Settings for US Adults: A Narrative Review of Systematic Reviews and Meta-analyses, 2010-2020.

Mental health and substance use disorders can negatively affect physical health, illness management, care access, and quality of life. These behavioral health conditions are prevalent and undertreated among people with HIV and may worsen outcomes along the entire HIV Care Continuum. This narrative review of tested interventions for integrating care for HIV and behavioral health disorders summarizes and contextualizes findings from systematic reviews and meta-analyses conducted in the past decade.

Observed humidity trends in dry regions contradict climate models.

Arid and semi-arid regions of the world are particularly vulnerable to greenhouse gas-driven hydroclimate change. Climate models are our primary tool for projecting the future hydroclimate that society in these regions must adapt to, but here, we present a concerning discrepancy between observed and model-based historical hydroclimate trends. Over the arid/semi-arid regions of the world, the predominant signal in all model simulations is an increase in atmospheric water vapor, on average, over the last four decades, in association with the increased water vapor-holding capacity of a warmer atmosphere.

A Systematic Review of Intervention Studies That Address HIV-Related Stigmas Among US Healthcare Workers and Health Systems: Applying a Theory-Based Ontology to Link Intervention Types, Techniques, and Mechanisms of Action to Potential Effectiveness.

Background: To end the HIV epidemic, we need to better understand how to address HIV-related stigmas in healthcare settings, specifically the common theoretical bases across interventions so that we can generalize about their potential effectiveness.

Purpose: We describe theory-based components of stigma interventions by identifying their functions/types, techniques, and purported mechanisms of change.

Methods: This systematic review examined studies published by April 2021.

Efficacy of a Dual-Epitope Dendritic Cell Vaccine as Part of Combined Immunotherapy for HER2-Expressing Breast Tumors.

Previous work from our group and others has shown that patients with breast cancer can generate a T cell response against specific human epidermal growth factor 2 (HER2) epitopes. In addition, preclinical work has shown that this T cell response can be augmented by Ag-directed mAb therapy. This study evaluated the activity and safety of a combination of dendritic cell (DC) vaccination given with mAb and cytotoxic therapy.

Predictors of Developmental and Adaptive Behaviour Outcomes in Response to Early Intensive Behavioural Intervention and the Early Start Denver Model.

Many autistic children require support to meet their learning needs. Given the heterogeneity within the autism spectrum it is plausible that different types of support might be better suited to different children. However, knowledge on what interventions work best for which children is limited.

Sexual health services in urban, suburban, and rural outpatient mental healthcare settings in New York: findings from a survey of practices and gaps.

We surveyed all licensed outpatient mental health programs in New York to examine sexual health services and training needs of providers. Gaps were found in processes for assessing whether patients were sexually active, engaging in sexual risk behaviours, and in need of HIV testing and pre-exposure prophylaxis. Significant differences between urban, suburban, and rural settings statewide were found in how the following sexual health services were delivered: education; on-site sexually transmitted infection screenings; and condom distribution and barriers to distribution.

A potential syndemic effect associated with symptoms of depression among men who have sex with men.

Introduction: Globally, depression rates are high among men who have sex with men (MSM). Multiple factors may interact synergistically to increase this risk. This analysis assessed the prevalence of symptoms of depression among MSM in Brazil and synergistic effects of several factors.

Reducing Intersecting Stigmas in HIV Service Organizations: An Implementation Science Model.

Background: HIV-related and intersectional stigmas are key barriers for service delivery, but best practices are nascent for addressing them in high-resource and high-burden contexts such as New York City (NYC). The Stigma Reduction and Resilience (STAR) implementation science (IS) Mapping Project in 2020 identified untested stigma reduction efforts in HIV organizations, highlighting the need for an IS framework.

Setting: Organizations providing HIV prevention and/or care in NYC.

Growing impact of wildfire on western US water supply.

Streamflow often increases after fire, but the persistence of this effect and its importance to present and future regional water resources are unclear. This paper addresses these knowledge gaps for the western United States (WUS), where annual forest fire area increased by more than 1,100% during 1984 to 2020. Among 72 forested basins across the WUS that burned between 1984 and 2019, the multibasin mean streamflow was significantly elevated by 0.

Evaluating the efficacy of a priming dose of cyclophosphamide prior to pembrolizumab to treat metastatic triple negative breast cancer.

Purpose: Triple negative breast cancer (TNBC) is characterized by the presence of immune cells in the tumor microenvironment, however, the response to single-agent immune checkpoint inhibitor (ICI) therapy is modest. Preclinical models have demonstrated that intratumoral regulatory T cells (T) dampen the antitumor response to ICI. We performed a single-arm phase II trial to evaluate the efficacy of a single low dose of cyclophosphamide (Cy) to deplete T administered before initiating pembrolizumab.

Phase II Trial of Pembrolizumab after High-Dose Cytarabine in Relapsed/Refractory Acute Myeloid Leukemia.

Unlabelled: Immune suppression, exhaustion, and senescence are frequently seen throughout disease progression in acute myeloid leukemia (AML). We conducted a phase II study of high-dose cytarabine followed by pembrolizumab 200 mg i.v.

HIV and Intersectional Stigma Reduction Among Organizations Providing HIV Services in New York City: A Mixed-Methods Implementation Science Project.

Stigma remains a pervasive barrier to Ending the HIV Epidemic (EHE) in New York City (NYC). As part of an EHE implementation science planning process, we mapped multi-level HIV-related stigma-reduction activities, assessed their evidence base, and characterized barriers and facilitators. We interviewed and surveyed a convenience sample of 27 HIV prevention and/or treatment services organizations in NYC, March-August, 2020, using an embedded mixed-methods design.

Targeting the IL-2 inducible kinase in melanoma; a phase 2 study of ibrutinib in systemic treatment-refractory distant metastatic cutaneous melanoma: preclinical rationale, biology, and clinical activity (NCI9922).

Background: IL-2 inducible kinase (ITK) is highly expressed in metastatic melanomas and its inhibition suppresses melanoma cell proliferation. We hypothesize that ibrutinib has a direct antitumor effect in melanoma cell lines and that treatment of metastatic melanomas with ibrutinib induces antitumor responses.

Methods: We assessed the ibrutinib effect on melanoma cell proliferation, apoptosis, and motility.

The RESPECT study: a feasibility randomised controlled trial of a sexual health promotion intervention for people with serious mental illness in community mental health services in the UK.

Background: People with serious mental illness (SMI) have sexual health needs but there is little evidence to inform effective interventions to address them. In fact, there are few studies that have addressed this topic for people with SMI outside USA and Brazil. Therefore, the aim of the study was to establish the acceptability and feasibility of a trial of a sexual health promotion intervention for people with SMI in the UK.

Concurrent Definitive Immunoradiotherapy for Patients with Stage III-IV Head and Neck Cancer and Cisplatin Contraindication.

Purpose: Although cisplatin plus radiotherapy is a standard treatment of locally advanced head and neck squamous cell carcinoma (LA-HNSCC), cisplatin contraindication is common. Radiation elicits and promotes tumor-directed immune stimulation, which may potentiate anti-PD-1 therapy. We provide the first efficacy report of combined pembrolizumab and definitive radiotherapy in LA-HNSCC.

Three Decades and Counting: HIV Service Provision in Outpatient Mental Health Settings.

Objective: People with serious mental illness in the United States have higher human immunodeficiency virus (HIV) infection rates than the general U.S. population.

The impact of psychiatric symptoms on condom self-efficacy among people with serious mental illness.

Objective: To determine how psychiatric symptoms affect the self-efficacy of people with serious mental illness to protect themselves and their partners from HIV and other sexually transmitted infections (STIs) by using condoms.

Method: As part of a National Institute of Mental Health-Funded study, people with serious mental illness ( = 467) were recruited in public psychiatric outpatient clinics in Rio de Janeiro, Brazil for an HIV prevention intervention. We examined the effects of psychiatric symptom severity on condom self-efficacy at baseline across 4 symptom clusters: affect, positive, negative, and activation.

Challenges and opportunities in the science of research to practice: lessons learned from a randomized controlled trial of a sexual risk-reduction intervention for psychiatric patients in a public mental health system.

Objective: Human immunodeficiency virus (HIV) prevention efficacy trials with psychiatric patients have been conducted in research settings in high-resourced countries, establishing short-term efficacy for reducing sexual risk behavior. None has been implemented within systems of care. In the last decade, overcoming this research-to-practice gap has become a focus of implementation science.
