Visualizing RNA structure ensembles by single-molecule correlated chemical probing.

RNA molecules fold to form complex internal structures. Many of these RNA structures populate ensembles with rheostat-like properties, with each state having a distinct function. Until recently, analysis of RNA structures, especially within cells, was limited to modeling either a single averaged structure or computationally-modeled ensembles.

Patient Satisfaction With a Coach-Guided, Technology-Based Mental Health Treatment: Qualitative Interview Study and Theme Analysis.

Background: Technology-based mental health interventions address barriers rural veterans face in accessing care, including provider scarcity and distance from the hospital or clinic. webSTAIR is a 10-module, web-based treatment based on Skills Training in Affective and Interpersonal Regulation, designed to treat posttraumatic stress disorder and depression in individuals exposed to trauma. Previous work has demonstrated that webSTAIR is acceptable to participants and effective at reducing symptoms of posttraumatic stress disorder and depression when delivered synchronously or asynchronously (over 5 or 10 sessions).

Understanding Prescribing Practices and Patient Experiences with Renin Angiotensin System Inhibitors Use in Chronic Kidney Disease: A Qualitative Study.

Introduction: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) improve outcomes but are underutilized in patients with chronic kidney disease (CKD). Little is known about reasons for discontinuation and lack of reinitiating these medications. We aimed to explore clinicians' and patients' experiences and perceptions of ACEI/ARB use in CKD.

Synthesis of findings from the literature and a qualitative research study on the impacts of gender, disability, and ethnicity in Neglected Tropical Diseases programs.

Introduction: Act to End NTDs | West, a USAID-funded program that supports national governments to eliminate or control five neglected tropical diseases (NTDs) in West Africa including trachoma, lymphatic filariasis (LF), onchocerciasis, schistosomiasis and soil-transmitted helminthiasis, conducted a gender and social inclusion analysis to determine how NTDs differentially impact various populations and how gender and social norms impact NTD programs to inform future programming.

Methods: The study used a mixed methods approach including a literature review; primary qualitative data collection; and monitoring data in Côte d'Ivoire, Sierra Leone, and Ghana.

Results: Women and girls face additional health risks from many NTDs compared to men and boys.

Documented Adverse Drug Reactions and Discontinuation of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers in Chronic Kidney Disease.

Introduction: Angiotensin-converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) are frequently discontinued in patients with chronic kidney disease (CKD). Documented adverse drug reactions (ADRs) in medical records may provide insight into the reasons for treatment discontinuation.

Methods: In this retrospective cohort of US veterans from 2005 to 2019, we identified individuals with CKD and a current prescription for an ACEi or ARB (current user group) or a discontinued prescription within the preceding 5 years (discontinued group).

A Scoping Review of Oral Pre-exposure Prophylaxis for Cisgender and Transgender Adolescent Girls and Young Women: What Works and Where Do We Go from Here?

Adolescent girls and young women (AGYW) are disproportionately affected by HIV, and oral pre-exposure prophylaxis (PrEP) can reduce HIV acquisition. The purpose of this scoping review was to synthesize results from interventions along the PrEP continuum for AGYW to inform research and programs. We searched electronic databases for studies published between January 2012-July 2021 and conducted secondary reference searching.

Two mental models of integrated care for advanced liver disease: qualitative study of multidisciplinary health professionals.

Objectives: The purpose of this paper is to present two divergent mental models of integrated advanced liver disease (AdvLD) care among 26 providers who treat patients with AdvLD.

Setting: 3 geographically dispersed United States Veterans Health Administration health systems.

Participants: 26 professionals (20 women and 6 men) participated, including 9 (34.

RNA-Ligand Interactions Quantified by Surface Plasmon Resonance with Reference Subtraction.

Structured RNAs bind ligands and are attractive targets for small-molecule drugs. A wide variety of analytical methods have been used to characterize RNA-ligand interactions, but our experience is that most have significant limitations in terms of material requirements and applicability to complex RNAs. Surface plasmon resonance (SPR) potentially overcomes these limitations, but we find that the standard experimental framework measures notable nonspecific electrostatic-mediated interactions, frustrating analysis of weak RNA binders.

The chosen and the unchosen: How eligibility for liver transplant influences the lived experiences of patients with advanced liver disease.

Advanced liver disease is often uncurable and fatal. Liver transplant is the only curative option for patients with advanced, irreversible liver disease, but the need for new livers far exceeds the supply. Patients with the greatest need as well as the greatest likelihood of benefit, based on a complex array of biomedical and psychosocial considerations, are prioritized for transplant.

Discovery of a large-scale, cell-state-responsive allosteric switch in the 7SK RNA using DANCE-MaP.

7SK is a conserved noncoding RNA that regulates transcription by sequestering the transcription factor P-TEFb. 7SK function entails complex changes in RNA structure, but characterizing RNA dynamics in cells remains an unsolved challenge. We developed a single-molecule chemical probing strategy, DANCE-MaP (deconvolution and annotation of ribonucleic conformational ensembles), that defines per-nucleotide reactivity, direct base pairing interactions, tertiary interactions, and thermodynamic populations for each state in RNA structural ensembles from a single experiment.

Prognosis conversations in advanced liver disease: A qualitative interview study with health professionals and patients.

Advanced Liver Disease (AdvLD) is common, morbid, and associated with high likelihood of death. Patients may not fully understand their prognosis and are often unprepared for the course of illness. Little is known about how and when to deliver prognosis-related information to patients with AdvLD, who should participate, and what should be discussed.

The value of peer support for self-management of diabetes among veterans in the Empowering Patients In Chronic care intervention.

Aim: To examine the value of peer support in the self-management of diabetes among veterans in an integrated health care system.

Methods: We conducted semi-structured in-depth interviews with veterans and clinicians 6 months after their participation in Empowering Patients in Chronic Care (EPIC), a group-based diabetes intervention with a peer-support component. Interviews elicited clinicians' narratives of how peer support unfolded in the groups and veterans' experiences of giving and receiving support from their peers.

Gender and neglected tropical disease front-line workers: Data from 16 countries.

Background: Delivery of preventive chemotherapy (PC) through mass drug administration (MDA) is used to control or eliminate five of the most common neglected tropical diseases (NTDs). The success of an MDA campaign relies on the ability of drug distributors and their supervisors-the NTD front-line workers-to reach populations at risk of NTDs. In the past, our understanding of the demographics of these workers has been limited, but with increased access to sex-disaggregated data, we begin to explore the implications of gender and sex for the success of NTD front-line workers.

Integrated Model for Patient-Centered Advanced Liver Disease Care.

Advanced liver disease (AdvLD) is a high-risk common condition with a progressive, highly morbid, and often fatal course. Despite effective treatments, there are substantial shortfalls in access to and use of evidence-based supportive and palliative care for AdvLD. Although patient-centered, chronic illness models that integrate early supportive and palliative care with curative treatments hold promise, there are several knowledge gaps that hinder development of an integrated model for AdvLD.

Barriers and Facilitators to the Use of Genomic-Based Targeted Lung Cancer Therapies in the VA: Qualitative Findings.

Reflexive testing, standardization of the mutation test ordering procedure and results reporting, and elimination of the preauthorization requirements could facilitate the utilization of targeted therapies.

Synthesis of Enantiomerically Pure 6-Substituted-Piperazine-2-Acetic Acid Esters as Intermediates for Library Production.

The piperazine heterocycle is broadly exploited in FDA-approved drugs and biologically active compounds, but its chemical diversity is usually limited to ring nitrogen substitutions, leaving the four carbon atoms underutilized. Using an efficient four-step synthesis, chiral amino acids were transformed into 6-substituted piperazine-2-acetic acid esters as diastereomeric mixtures whose cis and trans products could be chromatographically separated. From six amino acids (both antipodes), a complete matrix of 24 monoprotected chiral 2,6-disubstituted piperazines was obtained, each as a single absolute stereoisomer in multigram quantities.

Utilization of genomic testing in advanced non-small cell lung cancer among oncologists in the Veterans Health Administration.

Current national guidelines recommend genomic testing on all stage 4 non-small cell lung cancers (NSCLC) of adenocarcinoma histology. Mutations are most often found among young, Asian, females without a history of smoking. As these characteristics are uncommon in the Veterans Health Administration (VHA) patient population, we sought to understand oncologists' decision-making processes regarding utilization of genomic testing in the VHA.

Qualitative findings on building a partnered approach to implementation of a group-based diabetes intervention in VA primary care.

Objective: Conduct a formative evaluation to inform the implementation of 'Empowering Patients in Chronic Care' (EPIC), an evidence-based interdisciplinary group medical appointment intervention to improve collaborative goal-setting in patients with treated but uncontrolled diabetes.

Design: The formative evaluation involved qualitative, in-depth interviews with clinicians, structured according to the Promoting Action on Research in Health Services framework. Interviews elicited (1) participants' knowledge regarding interdisciplinary group self-management and goal-setting programmes and how well clinicians embrace these interventions (evidence), (2) physical and social climate at each target facility and how the intervention can best be embedded into routine primary care (context) and (3) site-specific needs to be addressed by our implementation team and clinicians' preparedness and intentions to participate in the intervention (facilitation).

Veterans' Perspectives on Benefits and Drawbacks of Peer Support for Posttraumatic Stress Disorder.

Peer support has been increasingly utilized within the Department of Veterans Affairs and offers an opportunity to augment existing care for posttraumatic stress disorder (PTSD). The current study sought to examine Veterans' perspectives on the potential benefits and drawbacks of peer support for PTSD. A sample of 23 Veterans with substantial treatment experience completed one-time qualitative interviews that were transcribed and coded for thematic content using grounded theory methodology.

Changing Gender Norms and Reducing HIV and Violence Risk Among Workers and Students in China.

Global evidence demonstrates that inequitable gender norms negatively influence key health outcomes (e.g., violence, HIV/STI), and the importance of male involvement in prevention efforts.

Veterans' perspectives on initiating evidence-based psychotherapy for posttraumatic stress disorder.

Evidence-based psychotherapies (EBP) for posttraumatic stress disorder (PTSD) are effective at reducing symptoms and improving quality of life. Despite their effectiveness, few veterans receive EBP. To examine veterans' experiences initiating EBP for PTSD, we conducted qualitative interviews with those who completed at least 8 sessions of prolonged exposure (PE) or cognitive processing therapy (CPT).

Factors influencing the acquisition and correct and consistent use of the top-lit updraft cookstove in Uganda.

This study looked at the effects of select behavior change interventions on the purchase and the correct and consistent use of a locally fabricated top-lit updraft (TLUD) stove in Uganda. Behavior change interventions included training of community sales agents and village health team volunteers on household air pollution and correct use, referral of interested community members to sales agents, community cooking demonstrations, information flyers, and direct sales of TLUDs and processed wood. Qualitative and quantitative research methods shaped interventions and were used to understand attitudes and practices related to TLUD stove acquisition and use.
