Obicetrapib exhibits favorable physiochemical and pharmacokinetic properties compared to previous cholesteryl ester transfer protein inhibitors: An integrated summary of results from non-human primate studies and clinical trials.

Anacetrapib, a cholesteryl ester transfer protein (CETP) inhibitor previously under development, exhibited an usually extended terminal half-life and large food effect and accumulated in adipose tissue. Other CETP inhibitors have not shown such effects. Obicetrapib, a potent selective CETP inhibitor, is undergoing Phase III clinical development.

Mixed-valence state in the dilute-impurity regime of La-substituted SmB.

Homogeneous mixed-valence (MV) behaviour is one of the most intriguing phenomena of f-electron systems. Despite extensive efforts, a fundamental aspect which remains unsettled is the experimental determination of the limiting cases for which MV emerges. Here we address this question for SmB, a prototypical MV system characterized by two nearly-degenerate Sm and Sm configurations.

Differences Between RSV A and RSV B Subgroups and Implications for Pharmaceutical Preventive Measures.

Introduction: Understanding the differences between respiratory syncytial virus (RSV) subgroups A and B provides insights for the development of prevention strategies and public health interventions. We aimed to describe the structural differences of RSV subgroups, their epidemiology, and genomic diversity. The associated immune response and differences in clinical severity were also investigated.

Teaching and Learning About the Transgender Population: Student Reflections.

Background: Decreasing the disparities in health care for transgender people requires nursing to expand its knowledge base about the population. There is limited research and information about curricula integration inclusive of this population, yet much is written about the gap in nursing knowledge and education. There may be insufficient opportunities to expose students to the population as patients; therefore, creative education strategies are necessary.

Respiratory Syncytial Virus Sequelae Among Adults in High-Income Countries: A Systematic Literature Review and Meta-analysis.

Introduction: Respiratory syncytial virus (RSV) can cause severe respiratory infections in adults; however, information on associated sequelae is limited. This systematic literature review aimed to identify sequelae in adults within 1 year following RSV-related hospitalization or resolution of acute infection.

Methods: Studies were identified from Embase, MEDLINE, LILACS, SciELO, and grey literature.

Autonomous micro-focus angle-resolved photoemission spectroscopy.

Angle-resolved photoemission spectroscopy (ARPES) is a technique used to map the occupied electronic structure of solids. Recent progress in x-ray focusing optics has led to the development of ARPES into a microscopic tool, permitting the electronic structure to be spatially mapped across the surface of a sample. This comes at the expense of a time-consuming scanning process to cover not only a three-dimensional energy-momentum (E, kx, ky) space but also the two-dimensional surface area.

Attributable Cost of Adult Respiratory Syncytial Virus Illness Beyond the Acute Phase.

Background: Estimates of the cost of medically attended lower respiratory tract illness (LRTI) due to respiratory syncytial virus (RSV) in adults, especially beyond the acute phase, is limited. This study was undertaken to estimate the attributable costs of RSV-LRTI among US adults during, and up to 1 year after, the acute phase of illness.

Methods: A retrospective observational matched-cohort design and a US healthcare claims repository (2016-2019) were employed.

Rates of Lower Respiratory Tract Illness in US Adults by Age and Comorbidity Profile.

Introduction: While it is widely recognized that older adults, adults with chronic medical conditions (CMC), and adults with immunocompromising conditions (IC) are at increased risk of lower respiratory tract illness (LRTI), evidence of the magnitude of increased risk is limited. This study was thus undertaken to characterize rates of hospitalized and ambulatory LRTI among United States (US) adults by age and comorbidity profile.

Methods: A retrospective cohort design and US healthcare claims database (2016-2019) were employed.

Systematic Literature Review of Risk Factors for Poor Outcomes Among Adults With Respiratory Syncytial Virus Infection in High-Income Countries.

Unlabelled: Identification of risk factors for severe respiratory syncytial virus (RSV) disease in adults could facilitate their appropriate vaccine recommendations. We conducted a systematic literature review (last 10 years in PubMed/Embase) to identify quantitative estimates of risk factors for severe RSV infection outcomes in high-income countries. Severe outcomes from RSV infection included hospitalization, excess mortality, lower respiratory tract infection, or a composite measure: severe RSV, which included these outcomes and others, such as mechanical ventilation and extended hospital stay.

Charge density wave induced nodal lines in LaTe.

LaTe is a non-centrosymmetric material with time reversal symmetry, where the charge density wave is hosted by the Te bilayers. Here, we show that LaTe hosts a Kramers nodal line-a twofold degenerate nodal line connecting time reversal-invariant momenta. We use angle-resolved photoemission spectroscopy, density functional theory with an experimentally reported modulated structure, effective band structures calculated by band unfolding, and symmetry arguments to reveal the Kramers nodal line.

Pediatric Respiratory Syncytial Virus Diagnostic Testing Performance: A Systematic Review and Meta-analysis.

Background: Adding additional specimen types (eg, serology or sputum) to nasopharyngeal swab (NPS) reverse transcription polymerase chain reaction (RT-PCR) increases respiratory syncytial virus (RSV) detection among adults. We assessed if a similar increase occurs in children and quantified underascertainment associated with diagnostic testing.

Methods: We searched databases for studies involving RSV detection in persons <18 years using ≥2 specimen types or tests.

Obicetrapib plus ezetimibe as an adjunct to high-intensity statin therapy: A randomized phase 2 trial.

Background: Obicetrapib, a selective cholesteryl ester transfer protein (CETP) inhibitor, reduces low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), lipoprotein particles, and apolipoproteins, when added to high-intensity statin in patients with dyslipidemia.

Objective: To evaluate the safety and lipid-altering efficacy of obicetrapib plus ezetimibe combination therapy as an adjunct to high-intensity statin therapy.

Methods: This double-blind, randomized, phase 2 trial administered 10 mg obicetrapib plus 10 mg ezetimibe (n = 40), 10 mg obicetrapib (n = 39), or placebo (n = 40) for 12 weeks to patients with LDL-C >70 mg/dL and triglycerides (TG) <400 mg/dL, on stable high-intensity statin.

In Situ Exfoliation Method of Large-Area 2D Materials.

2D materials provide a rich platform to study novel physical phenomena arising from quantum confinement of charge carriers. Many of these phenomena are discovered by surface sensitive techniques, such as photoemission spectroscopy, that work in ultra-high vacuum (UHV). Success in experimental studies of 2D materials, however, inherently relies on producing adsorbate-free, large-area, high-quality samples.

Underascertainment of Respiratory Syncytial Virus Infection in Adults Due to Diagnostic Testing Limitations: A Systematic Literature Review and Meta-analysis.

Background: Most observational population-based studies identify respiratory syncytial virus (RSV) by nasal/nasopharyngeal swab reverse transcriptase real-time PCR (RT-PCR) only. We conducted a systematic review and meta-analyses to quantify specimen and diagnostic testing-based underascertainment of adult RSV infection.

Methods: EMBASE, PubMed, and Web of Science were searched (January 2000-December 2021) for studies including adults using/comparing >1 RSV testing approach.

Lipid lowering effects of the CETP inhibitor obicetrapib in combination with high-intensity statins: a randomized phase 2 trial.

Global guidelines for the management of high-cardiovascular-risk patients include aggressive goals for low-density lipoprotein cholesterol (LDL-C). Statin therapy alone is often insufficient to reach goals and nonstatin options have limitations. Here, we tested the lipid-lowering effects of the cholesteryl ester transfer protein (CETP) inhibitor drug obicetrapib in a randomized, double-blind, placebo-controlled trial in dyslipidaemic patients (n = 120, median LDL-C 88 mg dl) with background high-intensity statin treatment (NCT04753606).

Urinary excretion profile of prednisolone and prednisone after rectal administration: Significance in antidoping analysis.

The rectal administration of glucocorticoids, as well as any injectable, and oral ones, is currently prohibited by the World Anti-Doping Agency when occurs "in competition." A reporting level of 100 ng/ml for prednisolone and 300 ng/ml for prednisone was established to discriminate the allowed and the prohibited administration. Here, the urinary excretion profiles of prednisone and prednisolone were evaluated in five volunteers in therapy with glucocorticoid-based rectal formulations containing prednisone or prednisolone caproate.

Prior influenza vaccine is not a risk factor for bacterial coinfection in patients admitted to the ICU due to severe influenza.

Objective: To determine whether the prior usage of the flu vaccine is a risk factor for bacterial co-infection in patients with severe influenza.

Design: This was a retrospective observational cohort study of subjects admitted to the ICU. A propensity score matching, and logistic regression adjusted for potential confounders were carried out to evaluate the association between prior influenza vaccination and bacterial co-infection.

Immune Response to COVID-19 and mRNA Vaccination in Immunocompromised Individuals: A Narrative Review.

Immunocompromised individuals are at high risk of poor coronavirus disease 2019 (COVID-19) outcomes and demonstrate a lower immune response to COVID-19 vaccines, including to the novel mRNA vaccines that have been shown to elicit high neutralizing antibody levels. This review synthesized available data on the immune response to COVID-19 and critically assessed mRNA COVID-19 vaccine immunogenicity in this vulnerable subpopulation. Patients with various immunocompromising conditions exhibit diverse responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19 severity and mortality, and available vaccines elicit lower immune responses, particularly in solid organ transplant recipients.

Evaluation of COVID-19 vaccine breakthrough infections among immunocompromised patients fully vaccinated with BNT162b2.

Objective: To evaluate COVID-19 vaccine breakthrough infections among immunocompromised (IC) individuals.

Methods: Individuals vaccinated with BNT162b2 were selected from the US HealthVerity database (10 December 2020 July 2021). COVID-19 vaccine breakthrough infections were examined in fully vaccinated (≥14 days after 2nd dose) IC individuals (IC cohort), 12 mutually exclusive IC condition groups, and a non-IC cohort.

Burden of invasive group B Streptococcus disease in non-pregnant adults: A systematic review and meta-analysis.

Background: Streptococcus agalactiae or group B Streptococcus (GBS) has emerged as an important cause of invasive disease in adults, particularly among the elderly and those with underlying comorbidities. Traditionally, it was recognised as an opportunistic pathogen colonising and causing disease in pregnant women, neonates, and young infants. Reasons for the upsurge of invasive GBS (iGBS) among the elderly remain unclear, although it has been related to risk factors such as underlying chronic diseases, immunosenescence, impaired inflammatory response, and spread of virulent clones.

5α-reductase inhibitors: Evaluation of their potential confounding effect on GC-C-IRMS doping analysis.

5α-reductase inhibitors (5-ARIs) are considered by the World Anti-doping Agency as potential confounding factors in evaluating the athlete steroid profile, since they may interfere with the urinary excretion of several diagnostic compounds. We herein investigated 5α-reductase inhibitors from a different perspective, by verifying their influence on the carbon isotopic composition of 5α- and 5β-reduced testosterone and nandrolone metabolites. The GC-C-IRMS analysis was performed on a set of urine samples collected from three male Caucasian volunteers after the acute and chronic administration of finasteride in combination with the intake of 19-norandrostenedione, a nandrolone precursor.

Prior influenza vaccine is not a risk factor for bacterial coinfection in patients admitted to the ICU due to severe influenza.

Objective: To determine whether the prior usage of the flu vaccine is a risk factor for bacterial co-infection in patients with severe influenza.

Design: This was a retrospective observational cohort study of subjects admitted to the ICU. A propensity score matching, and logistic regression adjusted for potential confounders were carried out to evaluate the association between prior influenza vaccination and bacterial co-infection.

Unusual reversibility in molecular break-up of PAHs: the case of pentacene dehydrogenation on Ir(111).

In this work, we characterize the adsorption of pentacene molecules on Ir(111) and their behaviour as a function of temperature. While room temperature adsorption preserves the molecular structure of the five benzene rings and the bonds between carbon and hydrogen atoms, we find that complete C-H molecular break up takes place between 450 K and 550 K, eventually resulting in the formation of small graphene islands at temperatures larger than 800 K. Most importantly a reversible temperature-induced dehydrogenation process is found when the system is annealed/cooled in a hydrogen atmosphere with a pressure higher than 5 × 10 mbar.
