Experience of primary dental care teams in managing the oral health of oncology patients.

Background: Estimates suggest that one in two people will experience cancer in their lifetime. Cancer and the treatment of cancer can have several impacts on oral health. It is therefore important that dental teams are supported in managing this group of patients especially in primary care dental settings, where most of these patients will first present to dental services.

segcsvd: A Convolutional Neural Network-Based Tool for Quantifying White Matter Hyperintensities in Heterogeneous Patient Cohorts.

White matter hyperintensities (WMH) of presumed vascular origin are a magnetic resonance imaging (MRI)-based biomarker of cerebral small vessel disease (CSVD). WMH are associated with cognitive decline and increased risk of stroke and dementia, and are commonly observed in aging, vascular cognitive impairment, and neurodegenerative diseases. The reliable and rapid measurement of WMH in large-scale multisite clinical studies with heterogeneous patient populations remains challenging, where the diversity of imaging characteristics across studies adds additional complexity to this task.

Outcomes for Younger Patients with Femoral Neck Fractures.

Background: There is a paucity of longer-term outcome data in younger adult patients who undergo fixation for an intracapsular hip fracture. The aims of this study were to evaluate the outcomes for young adult patients undergoing intracapsular hip fracture fixation and to assess factors associated with failure and patient-reported outcome measures (PROMs).

Methods: From 2008 to 2018, 112 consecutive patients ≤60 years of age (mean age, 48 years [range, 20 to 60 years]; 54% male) were retrospectively identified as having undergone fixation of an intracapsular hip fracture.

Colorimetric Hybridization Sensor for DNA Mimic of a SARS-CoV-2 RNA Marker: Direct and Inverse Bioanalysis.

This article presents a colorimetric visual biosensor designed for direct application in undiluted biofluids, which holds significant promise for point-of-need applications. Unlike traditional biosensors that struggle with heavily diluted sample matrices, the presented biosensor does not require any instrumentation or trained personnel, making it highly practical. The sensor features an oligonucleotide probe covalently attached to magnetically separable magnetite (FeO) particles.

Phase II randomized study of dostarlimab alone or with bevacizumab versus non-platinum chemotherapy in recurrent gynecological clear cell carcinoma (DOVE/APGOT-OV7/ENGOT-ov80).

Background: Recurrent gynecological clear cell carcinoma (rGCCC) has a low objective response rate (ORR) to chemotherapy. Previous preclinical and clinical data suggest a potential synergy between immune checkpoint inhibitors and bevacizumab in rGCCC. Dostarlimab, a humanized monoclonal antibody targeting programmed cell death protein 1 (PD-1), combined with the anti-angiogenic bevacizumab, presents a novel therapeutic approach.

Structural insights into the enzymatic breakdown of azomycin-derived antibiotics by 2-nitroimdazole hydrolase (NnhA).

The antibiotic 2-nitroimidazole (2NI) or azomycin, used for treating drug-resistant tuberculosis and imaging tumor hypoxia, requires activation by bacterial nitroreductases for its antibiotic and cytotoxic effect. Mycobacterium sp. JS330 produces 2-nitroimidazole nitrohydrolase (NnhA) that circumvents 2NI activation, conferring 2NI resistance by hydrolysing it to nitrite and imidazol-2-one (IM2O) instead.

Impact of Intracellular Proteins on μ-Opioid Receptor Structure and Ligand Binding.

Chronic pain is a prevalent problem affecting approximately one out of every five adults in the U.S. The most effective way to treat chronic pain is with opioids, but they cause dangerous side effects such as tolerance, addiction, and respiratory depression, which makes them quite deadly.

Supporting equitable cervical cancer elimination for Australia's culturally and linguistically diverse communities: A call for intersectoral action.

Cervical cancer is a preventable disease and is related to persistent health equities. Whilst several priority populations face health inequities related to cervical cancer prevention, my co-authors and I bring special attention to those who identify as culturally and linguistically diverse (CALD). By reflecting on some of our research and work experiences, we propose four ways that governments and policymakers can enact the community engagement goals of the published and proposed cervical cancer prevention and treatment strategies for CALD communities.

A prognostic molecular signature of hepatic steatosis is spatially heterogeneous and dynamic in human liver.

Hepatic steatosis is a central phenotype in multi-system metabolic dysfunction and is increasing in parallel with the obesity pandemic. We use a translational approach integrating clinical phenotyping and outcomes, circulating proteomics, and tissue transcriptomics to identify dynamic, functional biomarkers of hepatic steatosis. Using multi-modality imaging and broad proteomic profiling, we identify proteins implicated in the progression of hepatic steatosis that are largely encoded by genes enriched at the transcriptional level in the human liver.

Sedation during dynamic bronchoscopy for expiratory central airway collapse: Which is the ideal protocol?

Objective: To compare sedation protocols for dynamic bronchoscopy (DB) in the evaluation of expiratory central airway collapse (ECAC).

Materials And Methods: This observational study included adult patients (≥18 years) referred to Mayo Clinic, Jacksonville, FL, from March 2023 to July 2024, for suspected ECAC. Patients were grouped based on sedation protocols: propofol (Protocol 1), remimazolam (Protocol 2), and remimazolam/fentanyl (Protocol 3).

Protein-coding mutation in Adcy3 increases adiposity and alters emotional behaviors sex-dependently in rats.

Objective: Adenylate cyclase 3 (Adcy3) has been linked to both obesity and major depressive disorder. We identified a protein-coding variant in the transmembrane (TM) helix of Adcy3 in rats; similar obesity variants have been identified in humans. This study investigates the role of a TM variant in adiposity and behavior.

The Estimated Lifetime Risk of Revision After Primary Knee Arthroplasty Is Influenced by Implant Design and Patient Age: Data From the National Joint Registries.

Background: The aim of this study was to determine the lifetime risk of revision surgery after primary knee arthroplasty (KA) according to implant choice and patient age.

Methods: The risk of revision according to the implant type (unicondylar, unconstrained, semiconstrained, and fully constrained) was obtained from the National Joint Registry of England and Wales. Mortality risk according to age was estimated from the Scottish Arthroplasty Project (1998 to 2019).

Anesthetic technique and postoperative pulmonary complications (PPC) after Video Assisted Thoracic (VATS) lobectomy: A retrospective observational cohort study.

Introduction: Thoracic surgery is associated with an 8-10% incidence of postoperative pulmonary complications (PPCs). Introduction of minimally invasive Video-assisted thoracoscopic surgery (VATS) aimed to reduce pain related and pulmonary complications. However, PPCs remain a common cause of morbidity after VATS.

Effects of a novel GABA-B positive allosteric modulator, ASP8062, on alcohol cue-elicited craving and naturalistic alcohol consumption in a multisite randomized, double-blind, placebo-controlled trial.

Background: The γ-aminobutyric acid-B (GABA) receptor is a promising target for the development of new medications to treat alcohol use disorder (AUD). The GABA agonist baclofen has been reported to reduce alcohol consumption but is associated with some undesirable side effects, including sedation. ASP8062 is a novel compound that acts as a positive allosteric modulator at the GABA receptor and may be more tolerable than baclofen.

Operatively Managed Transverse or Short Oblique B1 Periprosthetic Fractures Around a Polished Taper-Slip Femoral Stem Are Associated With Reoperation in One Third of Cases: A Retrospective Cohort Study.

Background: Transverse or short oblique periprosthetic femoral fractures around total hip arthroplasty (THA) stems are typically classified as B1 fractures (stem well-fixed) and usually managed with fixation. These fractures have high non-union rates. This study aimed to identify reoperation rates in patients with operatively managed transverse or short oblique fractures around a cemented polished taper-slip stem and determine any associations with treatment failure.

Exercise-Induced Reduction in Left Ventricular Ejection Fraction in the Absence of Coronary Artery Disease: Clinical Characteristics and Outcomes.

Background: During exercise stress echocardiography (ESE), there are patients with normal left ventricular ejection fraction (LVEF) who paradoxically develop reduced LVEF during exercise despite absence of coronary artery disease (CAD) and a significant hypertensive response. This study sought to describe the clinical features and outcomes of this population.

Methods: Among ESEs performed between 2003 and 2022, patients without CAD by angiogram within 90 days of ESE and resting LVEF ≥50% with a ≥5% LVEF decrease during ESE were included.

Unlocking success: community engagement for enhanced HIV care outcomes.

Background: Though social determinants are the primary drivers of health, few studies of people living with HIV focus on non-clinical correlates of insecure and/or fragmented connections with the care system. Our team uses linked clinical and multisector non-clinical data to study how residential mobility and connection to social services influence the HIV care continuum. We engage a diverse group of individuals living with HIV and other invested community members to guide and inform this research.

Effect of Hypoxia on Siglec-7 and Siglec-9 Receptors and Sialoglycan Ligands and Impact of Their Targeting on NK Cell Cytotoxicity.

Background/objectives: Tumor microenvironmental hypoxia is an established hallmark of solid tumors. It significantly contributes to tumor aggressiveness and therapy resistance and has been reported to affect the balance of activating/inhibitory surface receptors' expression and activity on NK cells. In the current study, we investigated the impact of hypoxia on the surface expression of Siglec-7 and Siglec-9 (Sig-7/9) and their ligands in NK cells and tumor target cells.

Plasma prolactin and postmenopausal breast cancer risk: a pooled analysis of four prospective cohort studies.

Background: Prolactin, a hormone produced by the pituitary gland, regulates breast development and may contribute to breast cancer etiology. However, most epidemiologic studies of prolactin and breast cancer have been restricted to single, often small, study samples with limited exploration of effect modification.

Methods: The Biomarkers in Breast Cancer Risk Prediction consortium includes 8,279 postmenopausal women sampled from four prospective cohort studies, of whom 3,441 were diagnosed with invasive breast cancer after enrollment.
