Comparing freshwater mussel responses to stress using life-history and Dynamic Energy Budget theory.

Freshwater mussels are experiencing severe population declines, affecting their critical role in freshwater ecosystems. A thorough assessment of threats posed by various stressors is needed; however, the large number of species to be considered and significant data gaps, especially for listed species, hinder the process. We combined a traits-based approach to represent multiple species grouped into three life-history categories - Equilibrium, Opportunistic, and Periodic - with the Dynamic Energy Budget modeling principles to capture the physiological mechanisms driving individual-level responses.

The associations between calorie tracking, body image dissatisfaction, eating disorders, and menstrual cycle characteristics in resistance-trained athletes.

Background: While body image dissatisfaction (BID) and eating disorders (EDs) are relatively common in athletes (ranging from 11% to 67% of athletes, depending on the sport) [1], they are also prevalent in weight-class restricted sports (a common format in strength sports), and among physique athletes [2]. These athletes manipulate their nutrition to reach aesthetic or body weight standards and, in that process, may undergo prolonged periods of low energy availability. Low energy availability, defined as consuming insufficient energy for one's lean mass and exercise activity, can lead to Relative Energy Deficiency in sport (REDs), a syndrome that can impact menstrual cycle (MC) symptoms (and many other aspects of physiology and psychology) [3].

Utilization of Potassium Binders for the Management of Hyperkalemia in Chronic Kidney Disease: A Position Statement by US Nephrologists.

Two potassium (K) binders-patiromer sorbitex calcium and sodium zirconium cyclosilicate-are recommended by international guidelines for the management of hyperkalemia. There is, however, no universally accepted best practice for how to appropriately utilize K binders in the long-term clinical management of CKD. A panel of eight US-based nephrologists convened in October 2022 to develop a consensus statement regarding utilizing K binders in clinical practice to help manage patients with nonemergent, persistent/recurrent hyperkalemia in CKD.

Open laminectomy vs. minimally invasive laminectomy for lumbar spinal stenosis: a review.

Objectives: Lumbar spinal stenosis (LSS) refers to a narrowing of the space within the spinal canal, which can occur at any level but is most common in the lumbar spine. Open laminectomy and minimally invasive laminectomy (MIL) procedures are the most common surgical gold standard techniques for treating LSS. This study aims to review clinical and biomechanical literature to draw comparisons between open laminectomy and various MIL techniques.

Tranexamic Acid in Rhytidectomy: A Split-Face Multi-Institutional Study.

Tranexamic acid (TXA) has the ability to reduce intraoperative bleeding and facilitate hemostasis in addition to its anti-inflammatory properties that can potentially aid in recovery among patients who underwent rhytidectomy. To compare postoperative ecchymosis in patients who underwent rhytidectomy with TXA added to the tumescent anesthetic. A multi-institutional, single-blind study was performed on patients who underwent rhytidectomy.

Health disparities and health literacy challenges experienced by individuals with hearing loss: A scoping review.

Objective: The purpose of this scoping review is to explore health disparities and health literacy challenges encountered by U.S. adults with hearing loss when trying to seek specialized care and access to medical devices such as hearing aids.

Digital Image Processing to Detect Adaptive Evolution.

In recent years, advances in image processing and machine learning have fueled a paradigm shift in detecting genomic regions under natural selection. Early machine learning techniques employed population-genetic summary statistics as features, which focus on specific genomic patterns expected by adaptive and neutral processes. Though such engineered features are important when training data are limited, the ease at which simulated data can now be generated has led to the recent development of approaches that take in image representations of haplotype alignments and automatically extract important features using convolutional neural networks.

Localization of brain neuronal IL-1R1 reveals specific neural circuitries responsive to immune signaling.

Interleukin-1 (IL-1) is a pro-inflammatory cytokine that exerts a wide range of neurological and immunological effects throughout the central nervous system (CNS) and is associated with the etiology of affective and cognitive disorders. The cognate receptor for IL-1, Interleukin-1 Receptor Type 1 (IL-1R1), is primarily expressed on non-neuronal cells (e.g.

A Conservative Restorative Approach for a Patient With Cleft Palate: Replacing a Lateral Incisor and Enhancing Esthetics.

Young patients often times are poor candidates for implant-supported restorations due to ongoing jawbone development. This case report describes a viable restorative option for a 16-year-old patient who had a large cleft defect and a hopeless prognosis for the right lateral incisor. The clinician utilized a combination of a fixed bonded ceramic restoration to replace tooth No.

The Associations of Kratom (Mitragynine), Opioids, Other Substances, and Sociodemographic Variables to Drug Intoxication-related Mortality.

Introduction: The US age-adjusted drug overdose rate increased by 298%, with fentanyl being the main contributor to drug overdose deaths. The contribution of kratom to drug overdoses or intoxication is seldom reported despite its increasing use and detection among overdose decedents.

Methods: Our cross-sectional study utilized deidentified data from the Florida Department of Law Enforcement, 2020-2021 (N = 30,845).

Registered report: Cognitive ability, but not cognitive reflection, predicts expressing greater political animosity and favouritism.

Liberals and conservatives both express political animosity and favouritism. However, less is known about whether the same or different factors contribute to this phenomenon among liberals and conservatives. We test three different relationships that could emerge among cognitive ability, cognitive reflection and political group-based attitudes.

An update to the American Radium Society's appropriate use criteria of lower grade gliomas: Integration of IDH inhibitors.

The ARS brain committee recommends that vorasidenib may be appropriate for recurrent or residual IDH-mutant grade 2 oligodendroglioma or astrocytoma. Vorasidenib is usually not appropriate for completely resected grade 2 oligodendroglioma or astrocytoma, any grade 3 oligodendroglioma or astrocytoma, or combined with radiotherapy and/or chemotherapy for any grade 2-3 glioma.

Effects of Tirzepatide on the Clinical Trajectory of Patients with Heart Failure, a Preserved Ejection Fraction, and Obesity.

Background: Patients with heart failure, a preserved ejection fraction (HFpEF), and obesity have significant disability and suffer frequent exacerbations of heart failure. We hypothesized that tirzepatide, a long-acting agonist of glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors, would improve a comprehensive suite of clinical endpoints, including measures of health status, functional capacity, quality of life, exercise tolerance, patient well-being, and medication burden in these patients.

Methods: 731 patients in class II-IV heart failure, ejection fraction ≥50%, and body mass index ≥30 kg/m were randomized(double-blind) to tirzepatide(titrated up to 15mg subcutaneously weekly)(n=364) or placebo(n=367), added to background therapy for a median of 104 weeks (Q1=66, Q3=126 weeks).

Structural and social determinants of health: The multi-ethnic study of atherosclerosis.

Background: Researchers have increasingly recognized the importance of structural and social determinants of health (SSDOH) as key drivers of a multitude of diseases and health outcomes. The Multi-Ethnic Study of Atherosclerosis (MESA) is an ongoing, longitudinal cohort study of subclinical cardiovascular disease (CVD) that has followed geographically and racially/ethnically diverse participants starting in 2000. Since its inception, MESA has incorporated numerous SSDOH assessments and instruments to study in relation to CVD and aging outcomes.

Tirzepatide for Heart Failure with Preserved Ejection Fraction and Obesity.

Background: Obesity increases the risk of heart failure with preserved ejection fraction. Tirzepatide, a long-acting agonist of glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors, causes considerable weight loss, but data are lacking with respect to its effects on cardiovascular outcomes.

Methods: In this international, double-blind, randomized, placebo-controlled trial, we randomly assigned, in a 1:1 ratio, 731 patients with heart failure, an ejection fraction of at least 50%, and a body-mass index (the weight in kilograms divided by the square of the height in meters) of at least 30 to receive tirzepatide (up to 15 mg subcutaneously once per week) or placebo for at least 52 weeks.

A platform of ADAPTive scaffolds: development of CDR-H3 β-hairpin mimics into covalent inhibitors of the PD1/PDL1 immune checkpoint.

Aberrant and dysregulated protein-protein interactions (PPIs) drive a significant number of human diseases, which is why they represent a major class of targets in drug discovery. Although a number of high-affinity antibody-based drugs have emerged in this therapeutic space, the discovery of smaller PPI inhibitors is lagging far behind, underscoring the need for novel scaffold modalities. To bridge this gap, we introduce a biomimetic platform technology - adaptive design of antibody paratopes into therapeutics () - that enables the paratope-forming binding loops of antibodies to be crafted into large β-hairpin scaffolds ().

Effects of tirzepatide on circulatory overload and end-organ damage in heart failure with preserved ejection fraction and obesity: a secondary analysis of the SUMMIT trial.

Patients with obesity-related heart failure with preserved ejection fraction (HFpEF) display circulatory volume expansion and pressure overload contributing to cardiovascular-kidney end-organ damage. In the SUMMIT trial, patients with HFpEF and obesity were randomized to the long-acting glucose-dependent insulinotropic polypeptide receptor and glucagon-like peptide-1 receptor agonist tirzepatide (n = 364, 200 women) or placebo (n = 367, 193 women). As reported separately, tirzepatide decreased cardiovascular death or worsening heart failure.

Sequential Grafting of the Left Internal Thoracic Artery to the Left Anterior Descending Artery and Graft Failure.

Background: There is concern that left internal thoracic artery (LITA)-to diagonal (D)-to left anterior descending artery (LAD) grafts may be more susceptible to failure compared with single LITA-LAD grafts.

Methods: Pooled individual patient data from 8 clinical trials with systematic graft imaging were analyzed to assess the incidence of sequential LITA-D-LAD vs single LITA-LAD grafts. Mixed-effects multivariable logistic regression, adjusting for patient characteristics and clustering within trials, was used.
