Health-Related Quality of Life and Perceived Stigma in Eosinophilic Esophagitis: A Real-World, US, Web-Based Survey.

Background And Aims: Eosinophilic esophagitis (EoE) is associated with impaired health-related quality of life (HRQoL) and stigma perceptions. Therefore, we examined the real-world impact of EoE on the daily life and ability to function in adolescents (caregiver-reported) and adults with EoE in the United States of America in a noninterventional, cross-sectional, web-based survey.

Methods: HRQoL was assessed using the Short Form Health Survey (domains: vitality and social functioning) and the European Health Interview Survey (domain: sleep).

Primary auditory thalamus relays directly to cortical layer 1 interneurons.

Inhibitory interneurons within cortical layer 1 (L1-INs) integrate inputs from diverse brain regions to modulate sensory processing and plasticity, but the sensory inputs that recruit these interneurons have not been identified. Here we used monosynaptic retrograde tracing and whole-cell electrophysiology to characterize the thalamic inputs onto two major subpopulations of L1-INs in the mouse auditory cortex. We find that the vast majority of auditory thalamic inputs to these L1-INs unexpectedly arise from the ventral subdivision of the medial geniculate body (MGBv), the tonotopically-organized primary auditory thalamus.

Knowledge, Attitudes, and Practices Regarding Herpes Zoster Vaccination Among Specialists.

Recombinant zoster vaccine has been recommended by the US Advisory Committee on Immunization Practices (ACIP) for the prevention of herpes zoster (HZ) in immunocompetent adults aged at least 50 years since 2018. In January 2022, this was extended to immunodeficient/immunosuppressed adults aged at least 19 years. Key study objectives were to assess specialists' knowledge of the ACIP HZ vaccination recommendations, their attitudes toward HZ vaccination, and HZ vaccination practices/barriers.

United States Physicians' Knowledge, Attitudes, and Practices Regarding Meningococcal Vaccination for Healthy Adolescents and Young Adults.

Purpose: The United States Advisory Committee on Immunization Practices (ACIP) recommends vaccination against meningococcal serogroups A, C, W, and Y (MenACWY) for all 11-12-year-olds, with a booster dose for 16-year-olds, and against meningococcal serogroup B (MenB) for 16-23-year-olds under shared clinical decision-making (SCDM). However, uptake of the MenB vaccine and the MenACWY booster dose is low. This study investigated United States physicians' knowledge, attitudes, and practices regarding recommending MenB and MenACWY vaccines to non-high-risk older adolescents and young adults.

Physician Awareness of the Safe Use of Cyproterone Acetate in Europe: A Survey on the Effectiveness of Additional Risk Minimization Measures.

Background: Cyproterone acetate (CPA) is a synthetic progesterone derivative introduced in the 1970s and prescribed as antiandrogenic therapy for inoperable prostate cancer, sexual deviations in men, and signs of androgenization in women. In 2020, the CPA summary of product characteristics (SmPC) was revised to include an updated special warning and precaution about (1) the risk of meningioma with increasing cumulative dose and (2) contraindication in patients with meningioma or history of meningioma. A Direct Healthcare Professional Communication (DHPC) was distributed.

Hepatitis A and B vaccination in adults at risk: A survey of US healthcare providers' attitudes and practices.

This study aimed to evaluate the attitudes and practices of US healthcare professionals (HCPs) regarding the Advisory Committee on Immunization Practices (ACIP) vaccination recommendations on HepA and HepB for adult patients at risk of contracting these infections or experiencing complications of hepatitis disease. This cross-sectional, web-based survey of 400 US HCPs, which included nurse practitioners and family medicine, internal medicine, infectious disease, emergency department, and gastroenterology physicians, assessed HCPs' attitudes and practices regarding the ACIP recommendations for adult patients at risk for hepatitis disease. HCP participants were identified via a survey research panel.

Dopamine transporter trafficking and Rit2 GTPase: Mechanism of action and impact.

Following its evoked release, dopamine (DA) signaling is rapidly terminated by presynaptic reuptake, mediated by the cocaine-sensitive DA transporter (DAT). DAT surface availability is dynamically regulated by endocytic trafficking, and direct protein kinase C (PKC) activation acutely diminishes DAT surface expression by accelerating DAT internalization. Previous cell line studies demonstrated that PKC-stimulated DAT endocytosis requires both Ack1 inactivation, which releases a DAT-specific endocytic brake, and the neuronal GTPase, Rit2, which binds DAT.

Oral Lefamulin vs Moxifloxacin for Early Clinical Response Among Adults With Community-Acquired Bacterial Pneumonia: The LEAP 2 Randomized Clinical Trial.

Importance: New antibacterials are needed to treat community-acquired bacterial pneumonia (CABP) because of growing antibacterial resistance and safety concerns with standard care.

Objective: To evaluate the efficacy and adverse events of a 5-day oral lefamulin regimen in patients with CABP.

Design, Setting, And Participants: A phase 3, noninferiority randomized clinical trial conducted at 99 sites in 19 countries that included adults aged 18 years or older with a Pneumonia Outcomes Research Team (PORT) risk class of II, III, or IV; radiographically documented pneumonia; acute illness; 3 or more CABP symptoms; and 2 or more vital sign abnormalities.

Preferences for Adult Pneumococcal Vaccine Recommendations Among United States Health Care Providers.

Introduction: In 2014, the Advisory Committee on Immunization Practices (ACIP) of the US Centers for Disease Control and Prevention (CDC) recommended 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) for all adults aged ≥ 65 years, with a commitment to revisit the recommendation for PCV13 because of declining vaccine-type disease. The Evidence-to-Recommendation framework used by the ACIP includes review of evidence regarding feasibility and stakeholder acceptability, but no surveys of vaccinator preferences have been published in the literature.

Methods: Physicians (N = 700), physician assistants (N = 100), pharmacists (N = 100), and nurse practitioners (N = 100) who recently prescribed, administered, or recommended adult pneumococcal vaccine were surveyed in March 2018.

Conditional, inducible gene silencing in dopamine neurons reveals a sex-specific role for Rit2 GTPase in acute cocaine response and striatal function.

Dopamine (DA) signaling is critical for movement, motivation, and addictive behavior. The neuronal GTPase, Rit2, is enriched in DA neurons (DANs), binds directly to the DA transporter (DAT), and is implicated in several DA-related neuropsychiatric disorders. However, it remains unknown whether Rit2 plays a role in either DAergic signaling and/or DA-dependent behaviors.

Efficacy and Safety of Intravenous-to-oral Lefamulin, a Pleuromutilin Antibiotic, for the Treatment of Community-acquired Bacterial Pneumonia: The Phase III Lefamulin Evaluation Against Pneumonia (LEAP 1) Trial.

Background: Lefamulin, a pleuromutilin antibiotic, is active against pathogens commonly causing community-acquired bacterial pneumonia (CABP). The Lefamulin Evaluation Against Pneumonia (LEAP 1) study was a global noninferiority trial to evaluate the efficacy and safety of lefamulin for the treatment of CABP.

Methods: In this double-blind study, adults with CABP of Pneumonia Outcomes Research Team risk class ≥III were randomized 1:1 to receive lefamulin at 150 mg intravenously (IV) every 12 hours or moxifloxacin at 400 mg IV every 24 hours.

Adjuvant treatment patterns and outcomes in patients with stage IB-IIIA non-small cell lung cancer in France, Germany, and the United Kingdom based on the LuCaBIS burden of illness study.

Objectives: To inform health-technology assessments of new adjuvant treatments, we describe treatment patterns in patients with complete resection of stage IB-IIIA non-small cell lung cancer (NSCLC) in France, Germany, and the United Kingdom (UK).

Materials And Methods: Data were collected via medical record abstraction. Patients were aged ≥18 years with completely resected stage IB-IIIA NSCLC, diagnosed between 01 January 2009 and 31 December 2011.

Economic burden of resected (stage IB-IIIA) non-small cell lung cancer in France, Germany and the United Kingdom: A retrospective observational study (LuCaBIS).

Objectives: New adjuvant treatments are being developed for patients with resected non-small cell lung cancer (NSCLC). Due to scarcity of real-world data available for treatment costs and resource utilization, health technology and cost-effectiveness assessments can be limited. We estimated the burden and cost-of-illness associated with completely resected stage IB-IIIA NSCLC in France, Germany and the United Kingdom (UK).

Convergent Balancing Selection on the Mu-Opioid Receptor in Primates.

The mu opioid receptor is involved in many natural processes including stress response, pleasure, and pain. Mutations in the gene also have been associated with opiate and alcohol addictions as well as with responsivity to medication targeting these disorders. Two common and mutually exclusive polymorphisms have been identified in humans, A118G (N40D), found commonly in non-African populations, and C17T (V6A), found almost exclusively in African populations.

Dopamine Transporter Amino and Carboxyl Termini Synergistically Contribute to Substrate and Inhibitor Affinities.

Extracellular dopamine and serotonin concentrations are determined by the presynaptic dopamine (DAT) and serotonin (SERT) transporters, respectively. Numerous studies have investigated the DAT and SERT structural elements contributing to inhibitor and substrate binding. To date, crystallographic studies have focused on conserved transmembrane domains, where multiple substrate binding and translocation features are conserved.

Evidence-based medicine, appropriate-use criteria, and sports medicine: how best to develop meaningful treatment guidelines.

We propose using appropriate-use criteria (AUC) as the methodology of choice for formulating and disseminating evidence-based medicine guidelines in sports medicine and arthroscopy. AUC provide a structured process for integrating findings from the scientific literature with clinical judgment to produce explicit criteria for determining the appropriateness of specific treatments. The use of AUC will enable surgeons to treat patients in a more consistent manner based on expert clinical consensus and evidence-based medicine.

Naturally occurring, physiologically normal, primate chimeras.

Callitrichids, South American primates including marmosets and tamarins, have evolved a unique physiology. Twins share a placenta during gestation and exchange stem cells, resulting in naturally occurring chimeric adults. Our study used a quantitative PCR-based assay to address whether this chimerism was restricted to blood and other cells of the hematopoietic lineage or whether it extended to other somatic tissues.

Quantitative molecular assessment of chimerism across tissues in marmosets and tamarins.

Background: Marmosets are playing an increasingly large and important role in biomedical research. They share genetic, anatomical, and physiological similarities with humans and other primate model species, but their smaller sizes, reproductive efficiency, and amenability to genetic manipulation offer an added practicality. While their unique biology can be exploited to provide insights into disease and function, it is also important that researchers are aware of the differences that exist between marmosets and other species.
