Effect of fatigability on sprint time performance and force-velocity profile according to maturity status in young rugby players.

Little is known about the influence of fatigue in repeated overground sprinting on force-velocity properties in children and adolescents, while this ability to repeat sprints is important for future progress in rugby union. Sprint time decline is commonly used to assess fatigability. However, it does not provide data on biomechanical aspects of sprint performance such as maximal power, force, and velocity production.

Insights from a National Survey on Controlled Substance Diversion Practices in U.S. Hospital Pharmacies: Opportunities for Enhanced Surveillance and Compliance.

This study explored controlled substance (CS) diversion surveillance practices within hospital pharmacies across the United States. A survey with questions based on published CS diversion risk points was conducted in May 2024. A total of 66 participants from 31 states responded, with 54.

Development of a validated novel bead extraction method for the detection of anti-PEG antibodies in human serum.

Aims: Polyethylene glycol (PEG) is used in many applications including drug development. Due to exposure to environmental products, there is a high prevalence of preexisting anti-PEG antibodies in the global human population. The presence of anti-PEG antibodies is a concern for potentially reducing the efficacy of therapeutics after administration and represents a risk of safety events after exposure to PEGylated drug products.

Impaired Atrial and Ventricular Strain Predicts Heart Failure in Arrhythmogenic Right Ventricular Cardiomyopathy.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) increases the risk of heart failure (HF) and arrhythmias. Speckle-tracking echocardiography (STE) detects myocardial dysfunction, but its predictive role for HF in this population remains unclear.

Methods: Seventy-one patients with ARVC (age 43.

Impact of an enterprise controlled substance management system on labor and inventory costs.

Disclaimer: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

Activity Identification, Classification, and Representation of Wheelchair Sport Court Tasks: A Method Proposal.

Background: Monitoring player mobility in wheelchair sports is crucial for helping coaches understand activity dynamics and optimize training programs. However, the lack of data from monitoring tools, combined with a lack of standardized processing approaches and ineffective data presentation, limits their usability outside of research teams. To address these issues, this study aimed to propose a simple and efficient algorithm for identifying locomotor tasks (static, forward/backward propulsion, pivot/tight/wide rotation) during wheelchair movements, utilizing kinematic data from standard wheelchair mobility tests.

Association between Left Ventricular Geometry, Systolic Ejection Time, and Estimated Glomerular Filtration Rate in Ambulatory Patients with Preserved Left Ventricular Ejection Fraction.

Introduction: Cardiac function is important to quantify for risk stratification. Although left ventricular ejection fraction (LVEF) is commonly used, and identifies patients with poor systolic function, other easily acquired measures of cardiac function are needed, particularly to stratify patients with relatively preserved LVEF. LV relative wall thickness (RWT) has been associated with adverse clinical outcomes in patients with preserved LVEF, but the clinical relevance of this observation is not known.

Flow cytometry assay modifications: Recommendations for method validation based on CLSI H62 guidelines.

The Clinical and Laboratory Standards Institute (CLSI) H62-Validation of Assays Performed by Flow Cytometry guideline, released in 2021, provides recommendations for platform workflow and quality system essentials, instrument setup and standardization, assay development and optimization and fit-for-purpose analytical method validation. In addition, CLSI H62 includes some recommendations for the validation strategies after a validated flow cytometric method has been modified. This manuscript builds on those recommendations and discusses the impact of different types of assay modifications on assay performance.

PARCCS: A Machine Learning Risk-Prediction Model for Acute Peripartum Cardiovascular Complications During Delivery Admissions.

Background: Maternal mortality in the United States remains high, with cardiovascular (CV) complications being a leading cause.

Objectives: The purpose of this paper was to develop the PARCCS (Prediction of Acute Risk for Cardiovascular Complications in the Peripartum Period Score) for acute CV complications during delivery.

Methods: Data from the National Inpatient Sample (2016-2020) and International Classification of Diseases, Tenth Revision codes to identify delivery admissions were used.

A Machine Learning-Derived Score to Effectively Identify Heart Failure With Preserved Ejection Fraction.

Background: The diagnosis of heart failure with preserved ejection fraction (HFpEF) in the clinical setting remains challenging, especially in patients with obesity.

Objectives: This study aimed to identify novel predictors of HFpEF well suited for patients with obesity.

Methods: We performed a retrospective analysis of a well-characterized cohort of patients with obesity with HFpEF (n = 404; mean body mass index [BMI] 36.

Association of Gestational Diabetes With Subclinical Cardiovascular Disease.

Background: Gestational diabetes mellitus (GDM) is associated with increased long-term risk of cardiovascular disease but the cardiovascular structural and functional changes that contribute to risk are not well understood.

Objectives: The purpose of this study was to determine whether GDM is associated with adverse cardiac remodeling and endothelial dysfunction a decade after delivery, independent of type 2 diabetes.

Methods: Women with deliveries between 2008 and 2009 were initially selected from a prospective clinical cohort.

Virtual cardiovascular magnetic resonance training proves feasible and effective: survey data from international participants of the CMR Academy Berlin, Germany.

Aims: This study aims to evaluate the success of the cardiovascular magnetic resonance (CMR) imaging Academy Berlin's transition from in-person to online CMR imaging training during the global pandemic 2020 and to gather recommendations for future courses.

Methods And Results: We conducted an online survey targeting CMR course participants from both the pre-pandemic, in-person era and the pandemic, online era of the CMR Academy Berlin. The survey primarily used Likert-type questions to assess participants' experiences and preferences.

Implementation of flow cytometry testing on rare matrix samples: Special considerations and best practices when the sample is unique or difficult to obtain.

The publication of Clinical and Laboratory Standards Institute's guideline H62 has provided the flow cytometry community with much-needed guidance on development and validation of flow cytometric assays (CLSI, 2021). It has also paved the way for additional exploration of certain topics requiring additional guidance. Flow cytometric analysis of rare matrices, or unique and/or less frequently encountered specimen types, is one such topic and is the focus of this manuscript.

Towards a more individualised assessment of post-training fatigue in young footballers.

Despite improvements in training load and fatigue monitoring, fatigue status may adversely affect intrinsic risk factors, particularly in young footballers. This study aimed to better individualise the fatigue effects of a 75-min football training session in young elite male players. Eighteen players (15.
