The Multifactorial Relationship Between Bone Tissue Water and Stiffness at the Proximal Femur.

Bone mechanical function is determined by multiple factors, some of which are still being elucidated. Here, we present a multivariate analysis of the role of bone tissue composition in the proximal femur stiffness of cadaver bones (n = 12, age 44-93). Stiffness was assessed by testing under loading conditions simulating a sideways fall onto the hip.

Patient-centered outcomes for clinical trials in chronic rhinosinusitis with or without nasal polyps and allergic fungal rhinosinusitis.

Background: Chronic rhinosinusitis (inclusive of subtypes with nasal polyps [CRSwNP], without nasal polyps [CRSsNP], and allergic fungal rhinosinusitis [AFRS]) causes inflammation of the nose mucosa and paranasal sinuses. Unfortunately, evidence supporting use of clinical outcome assessments (COAs) in regulated clinical trials to assess key measurement concepts of these conditions is limited.

Objective: To identify key disease-related symptoms and impacts, potential outcomes of interest for new treatments, and COAs available to measure those outcomes among adult and adolescent individuals living with CRSwNP, CRSsNP, and AFRS.

Examination of Gallbladders at Military Treatment Facilities: Is Histologic Analysis Necessary?

Introduction: Gallbladder specimens from cholecystectomy procedures are a common specimen evaluated by military pathologists. These are often removed for inflammatory causes. Previous studies show that the incidence of gallbladder carcinoma (GBC) is around 3%.

Evolution of sleep disordered breathing in infants with achondroplasia.

Purpose: Children with achondroplasia (ACH) are at risk for sudden death in infancy due to sleep disordered breathing (SDB) and foramen magnum stenosis (FMS). Sleep studies and neuroimaging are performed in infants with ACH, but interpretation of infant studies is challenging. We sought to describe baseline data on polysomnography (PSG) indices in infants with achondroplasia as well as effects of age and surgery on these parameters.

Treatment of both bone forearm fractures with 2.7Â mm plates: a non-inferiority study.

Objectives: To determine the effectiveness of 2.7 mm plates in treating both bone forearm fractures (BBFFs) compared to the current gold standard of 3.5 mm fixation.

The interactive role of microRNA and other non-coding RNA in hepatitis B (HBV) associated fibrogenesis.

One of the outstanding features of chronic hepatitis B infection (CHB) is its strong association with liver fibrosis. CHB induced inflammation and injury trigger multiple biochemical and physical changes that include the promotion of a wide range of cytokines, chemokines and growth factors that activate hepatic stellate cells (HSCs) CHB induced activation of hepatic stellate cells (HSCs) is regarded as a central event in fibrogenesis to directly promote the synthesis of myofibroblasts and the expression of a range of materials to repair injured liver tissue. Fibrogenesis is modulated by the mainstream epigenetic machinery, as well as by non-coding RNA (ncRNA) that are often referred to as an ancillary epigenetic response to fine tune gene expression.

PARP12-mediated ADP-ribosylation contributes to breast cancer cell fate by regulating AKT activation and DNA-damage response.

Breast cancer represents the primary cause of death of women under 65 in developed countries, due to the acquisition of multiple drug resistance mechanisms. The PI3K/AKT pathway is one of the major regulating mechanisms altered during the development of endocrine resistance and inhibition of steps in this signalling pathway are adopted as a key strategy to overcome this issue. ADP-ribosylation is a post-translational modification catalysed by PARP enzymes that regulates essential cellular processes, often altered in diseases.

Impact of preoperative frailty status on decision regret following elective hernia repair.

Purpose: Decision regret following hernia repair is common, particularly for patients who experience complications. Frailty is a risk factor for complications, but whether frailty is independently associated with regret remains unknown.

Methods: We retrospectively reviewed the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry, a representative sample of adult patients from > 70 hospitals across Michigan.

Quantitative analysis of Δ- and Δ-tetrahydrocannabinol metabolites and isomers: a rapid assay in urine by LC-MS/MS.

An increasing number of cannabis-related products have become available and entered the market, particularly those containing cannabidiol (CBD) and Δ-tetrahydrocannabinol (Δ-THC). Analytical methods for cannabinoids in urine have been described extensively in the literature. However, methods providing good resolution for distinguishing interferences from THC positional isomers are needed.

Active targeting of type 1 diabetes therapies to pancreatic beta cells using nanocarriers.

Type 1 diabetes is an autoimmune disease characterised by the destruction of pancreatic beta cells, resulting in lifelong insulin dependence. Although exogenous insulin can maintain glycaemic control, this approach does not protect residual or replacement pancreatic beta cells from immune-mediated death. Current therapeutics designed to protect functional beta cell mass or promote beta cell proliferation and regeneration can have off-target effects, resulting in higher dose requirements and adverse side effects.

A physiologically based pharmacokinetic (PBPK) model describing the kinetics of a commercial mixture α-, β-, and γ-hexabromocyclododecane exposure in mice.

Hexabromocyclododecane (HBCD) is a brominated flame retardant, that is added, but not chemically bonded, to consumer products. HBCD is sold as a commercial-grade HBCD mixture containing three major stereoisomers: alpha (α), beta (β), and gamma (γ), with relative amounts of 12% for α-HBCD, 6% for β-HBCD, and 82% for γ-HBCD. HBCDs are widely measured in the environment and in biological matrices.

Catalyst-derived hierarchy in 2D imine-based covalent organic frameworks.

Identifying facile strategies for hierarchically structuring crystalline porous materials is critical for realizing diffusion length scales suitable for broad applications. Here, we elucidate synthesis-structure-function relations governing how room temperature catalytic conditions can be exploited to tune covalent organic framework (COF) growth and thereby access unique hierarchical morphologies without the need to introduce secondary templates or structure directing molecules. Specifically, we demonstrate how scandium triflate, an efficient catalyst involved in the synthesis of imine-based COFs, can be exploited as an effective growth modifier capable of selectively titrating terminal amines on 2D COF layers to facilitate anisotropic crystal growth.

Skeletal muscle elastic modulus in marathon distance runners.

Skeletal muscle shear elastic modulus is a non-invasive surrogate for early detection of muscle damage and soreness consequent to unaccustomed eccentric muscle work. We investigated the influence of marathon distance running on skeletal muscle shear elastic modulus. Shear modulus of the rectus femoris was measured via ultrasound shear wave elastography in 80 participants (30 female, 50 male) before and after running a World Marathon Major.

The Brussels consensus for non-invasive ICP monitoring when invasive systems are not available in the care of TBI patients (the B-ICONIC consensus, recommendations, and management algorithm).

Background: Invasive systems are commonly used for monitoring intracranial pressure (ICP) in traumatic brain injury (TBI) and are considered the gold standard. The availability of invasive ICP monitoring is heterogeneous, and in low- and middle-income settings, these systems are not routinely employed due to high cost or limited accessibility. The aim of this consensus was to develop recommendations to guide monitoring and ICP-driven therapies in TBI using non-invasive ICP (nICP) systems.

ACTB::ZMIZ2-rearranged adnexal carcinoma: a second case.

A case of cutaneous adnexal neoplasm with unusual squamoid morphology and harboring an in frame ACTB::ZMIZ2 fusion transcript was recently described. Herein, we report a second case of adnexal carcinoma harboring similar morphology and an identical in frame ACTB::ZMIZ2 fusion transcript. This 2.

Pediatric cancer predisposition syndromes involving non-central nervous system solid pediatric tumors: a review on their manifestations with a focus on histopathology.

Germline genetic alterations and their associated cancer predisposition syndromes (CPS) are an important cause of pediatric cancer. Early recognition is of great importance for targeted surveillance, early detection, and prompt (personalized) therapeutic interventions. This review provides an overview of non-central nervous system solid pediatric tumor types, in relation to their associated CPS, with an emphasis on their histology.

Cushing's syndrome related to higher rates and earlier onset of cataract: A nationwide retrospective cohort study.

Purpose: To investigate the risk of cataract in patients with Cushing's syndrome (CS) and evaluate whether disease onset occurs at an earlier age compared to general population.

Methods: A nationwide retrospective matched-cohort study including individuals diagnosed with endogenous CS from 2000 to 2023. Patients with CS were matched in a 1:5 ratio with a control group individually matched for age, sex, socioeconomic status, and body mass index.

Hypopituitarism Screening in Patients with Traumatic Brain Injury in the Primary Care Setting at the Minneapolis Veterans Affairs Health Care System.

Introduction: Traumatic brain injury (TBI) is a significant health issue among veterans and poses a substantial risk for pituitary injury. Consensus guidelines recommend that patients who have sustained a TBI should undergo a baseline pituitary hormonal evaluation after the primary brain insult. Patients with abnormal screening test results or with symptoms of hypopituitarism should be referred to endocrinology for a full assessment.

Entropy stabilized form chirality in curved rod nematics: structure and symmetries.

Monte Carlo molecular simulations of curve-shaped rods show the propensity of such shapes to polymorphism revealing both smectic and polar nematic phases. The nematic exhibits a nanoscale modulated local structure characterized by a unique, polar, -symmetry axis that tightly spirals generating a mirror-symmetry-breaking organization of the achiral rods-form chirality. A comprehensive characterization of the polarity and its symmetries in the nematic phase confirms that the nanoscale modulation is distinct from the elastic deformations of a uniaxial nematic director in the twist-bend nematic phase.

Impact of a community-based lifestyle intervention with initial sedentary reduction or physical activity increasing goals on self-reported health-related quality of life.

Background: In previous efforts, health-related quality of life (HRQoL) improved for individuals at high risk of type 2 diabetes and cardiovascular disease after participation in community-based lifestyle interventions (LI) with a moderate-to-vigorous physical activity (MVPA) movement goal.

Purpose: It is unknown whether HRQoL improves with LI when the primary movement goal is to reduce sedentary behavior. HRQoL changes were examined among adults with overweight and prediabetes and/or metabolic syndrome randomized to a 12-month Diabetes Prevention Program-based Group Lifestyle Balance (DPP-GLB) community LI work with goals of weight-loss and either increasing MVPA (DPP-GLB) or reducing sedentary time (GLB-SED).

Jan and mini-Jan, a model system for potato functional genomics.

Potato (Solanum tuberosum) is the third-most important food crop in the world. Although the potato genome has been fully sequenced, functional genomics research of potato lags behind that of other major food crops, largely due to the lack of a model experimental potato line. Here, we present a diploid potato line, 'Jan,' which possesses all essential characteristics for facile functional genomics studies.

Prognostic utility of assessing ventricular-arterial coupling in arterial hypertension and cardiovascular diseases.

The assessment of myocardial function and its coupling with the arterial system, called ventricular-arterial coupling (VAC), is of paramount importance in many clinical fields, from arterial hypertension, which is the main cause of cardiovascular diseases and death, to heart failure. VAC has been the subject of studies for several decades both from an energetic cost and the impact it can exert on cardiovascular performance. Although more attention has been paid to the relationship between the left ventricle and the left arterial circuit in compromised hemodynamic stages, VAC has aroused interest in many other aspects of study, from its application in pathologies of the right sections of the heart to its clinical impact in prevention and cardiovascular risk factors.
