Dysregulated Genes, MicroRNAs, Biological Pathways, and Gastrocnemius Muscle Fiber Types Associated With Progression of Peripheral Artery Disease: A Preliminary Analysis.

Background Peripheral artery disease (PAD) is associated with gastrocnemius muscle abnormalities. However, the biological pathways associated with gastrocnemius muscle dysfunction and their associations with progression of PAD are largely unknown. This study characterized differential gene and microRNA (miRNA) expression in gastrocnemius biopsies from people without PAD compared with those with PAD.

Training the next generation of learning health system scientists.

Introduction: The learning health system (LHS) aligns science, informatics, incentives, stakeholders, and culture for continuous improvement and innovation. The Agency for Healthcare Research and Quality and the Patient-Centered Outcomes Research Institute designed a K12 initiative to grow the number of LHS scientists. We describe approaches developed by 11 funded centers of excellence (COEs) to promote partnerships between scholars and health system leaders and to provide mentored research training.

Development of a learning health system science competency assessment to guide training and proficiency assessment.

Introduction: Learning health systems (LHS) science is fundamentally a transdisciplinary field. To capture the breadth of the competencies of an LHS scientist, AHRQ and national experts defined a series of 42 competencies across seven domains that support success. Clinicians, researchers, and leaders who are new to the LHS field can identify and prioritize proficiency development among these domains.

Trajectories of Depressive and Anxiety Symptoms Across Pregnancy and Postpartum in Selective Serotonin Reuptake Inhibitor-Treated Women.

Objective: Tracking perinatal mood and anxiety disorders is championed by the American Psychiatric Association and the International Marcé Society for Perinatal Mental Health. We conducted this study to examine trajectories of monthly depressive and anxiety symptoms through pregnancy and postpartum.

Methods: This is a prospective longitudinal observational cohort study of pregnant women interviewed at baseline (≤18th gestational week), every four weeks through delivery and at 6 and 14 weeks postpartum at three urban academic medical centers ( = 85) and a single rural health center ( = 3) from 2016 to 2020.

Left Atrial Function and Arrhythmias in Relation to Small Vessel Disease on Brain MRI: The Multi-Ethnic Study of Atherosclerosis.

Background Atrial fibrillation (AF) is associated with increased stroke risk and accelerated cognitive decline, but the association of early manifestations of left atrial (LA) impairment with subclinical changes in brain structure is unclear. We investigated whether abnormal LA structure and function, greater supraventricular ectopy, and intermittent AF are associated with small vessel disease on magnetic resonance imaging of the brain. Methods and Results In the Multi-Ethnic Study of Atherosclerosis, 967 participants completed 14-day ambulatory electrocardiographic monitoring, speckle tracking echocardiography and, a median 17 months later, magnetic resonance imaging of the brain.

Emergency department care transition barriers: A qualitative study of care partners of older adults with cognitive impairment.

Introduction: After emergency department (ED) discharge, persons living with cognitive impairment (PLWCI) and their care partners are particularly at risk for adverse outcomes. We sought to identify the barriers experienced by care partners of PLWCI during ED discharge care transitions.

Methods: We conducted a qualitative study of 25 care partners of PLWCI discharged from four EDs.

Time-Dependent Risk of Cardiovascular Events Following an Exacerbation in Patients With Chronic Obstructive Pulmonary Disease: Post Hoc Analysis From the IMPACT Trial.

Background The association between chronic obstructive pulmonary disease exacerbations and increased cardiovascular event risk has not been adequately studied in a heterogenous population with both low and high cardiovascular risk. Methods and Results This post hoc analysis of the IMPACT (Informing the Pathway of COPD Treatment) trial (N=10 355 symptomatic patients with chronic obstructive pulmonary disease at risk of exacerbations) evaluated time-dependent risk of cardiovascular adverse events of special interest (CVAESI) following exacerbations and impact of exacerbation history, cardiovascular risk factors, and study treatment on this association. Risk (time-to-first) of CVAESI or CVAESI resulting in hospitalization or death was assessed during and 1 to 30, 31 to 90, and 91 to 365 days after resolution of moderate or severe exacerbations.

Racial Disparity in Referral for Catheter Ablation for Atrial Fibrillation at a Single Integrated Health System.

Background Guidelines recommend catheter ablation of atrial fibrillation (AFCA) as an option for rhythm control. Studies have shown that Black patients are less likely to undergo AFCA compared with White patients. We investigated whether differences in referral patterns play a role in this observed disparity.

Blood-Based Fingerprint of Cardiorespiratory Fitness and Long-Term Health Outcomes in Young Adulthood.

Background Cardiorespiratory fitness is a powerful predictor of health outcomes that is currently underused in primary prevention, especially in young adults. We sought to develop a blood-based biomarker of cardiorespiratory fitness that is easily translatable across populations. Methods and Results Maximal effort cardiopulmonary exercise testing for quantification of cardiorespiratory fitness (by peak oxygen uptake) and profiling of >200 metabolites at rest were performed in the FHS (Framingham Heart Study; 2016-2019).

Outcomes of a postoperative day one call to families after adenotonsillectomy in children.

Objective: To examine the outcomes of a postoperative day one (POD 1) phone call to families of ambulatory surgical patients, as a means of guiding clinical interventions and quality initiatives, with a focus on children undergoing adenotonsillectomy (T&A).

Methods: Retrospective analysis of outcomes of a POD 1 questionnaire completed in children <18 years of age undergoing T&A at a tertiary care children's hospital over a 3-year period (August 14, 2018-August 31, 2021).

Results: Responses to the questionnaire were obtained for a total of 1428/3464 (41.

Psychological Therapies and Mind-Body Techniques in the Management of Dermatologic Diseases: A Systematic Review.

Background: There is a clear link between skin disease and psychological factors and this relationship works both ways: skin diseases can cause psychological distress and psychological issues can worsen skin disease. There are a number of therapies that approach this problem from the psychological side and may be useful, especially as adjunctive therapies in select patients.

Objective: The aim of this review was to determine the efficacy of various psychological therapies and mind-body techniques in the management of common dermatologic diseases in individuals of all ages.

Coronary Artery Calcium Score to Refine the Use of PCSK9i in Asymptomatic Individuals: A Multicohort Study.

Background The value of coronary artery calcium (CAC) in the allocation of PCSK9i (proprotein convertase subtilisin/kexin type 9 inhibitors) among individuals without clinically evident atherosclerotic cardiovascular disease (ASCVD) is unknown for indications that do not require confirmed familial hypercholesterolemia. We aimed to assess the ability of CAC to stratify ASCVD risk under 3 non-familial hypercholesterolemia PCSK9i allocation paradigms. Methods and Results We included participants without clinically evident ASCVD from MESA (Multi-Ethnic Study of Atherosclerosis), CARDIA (Coronary Artery Risk Development in Young Adults) study, DHS (Dallas Heart Study), and HNR (Heinz Nixdorf Recall) study.

Alzheimer's polygenic hazard score in SuperAgers: SuperGenes or SuperResilience?

Introduction: SuperAgers are individuals over age 80 with superior episodic memory, at a level consistent with individuals 20 to 30 years their junior and who seem to show resistance to age-related neurofibrillary degeneration. Here we examine whether low genetic risk for Alzheimer's disease (AD) contributes to SuperAgers' unusually high episodic memory performance in advanced age.

Methods: The AD polygenic hazard score (PHS) was calculated for each SuperAger and cognitively normal participant and compared between groups.

Effects of Walking Exercise at a Pace With Versus Without Ischemic Leg Symptoms on Functional Performance Measures in People With Lower Extremity Peripheral Artery Disease: The LITE Randomized Clinical Trial.

Background In people with peripheral artery disease, post hoc analyses of the LITE (Low Intensity Exercise Intervention in Peripheral Artery Disease) randomized trial were conducted to evaluate the effects of walking exercise at a pace inducing ischemic leg symptoms on walking velocity and the Short Physical Performance Battery, compared with walking exercise without ischemic leg symptoms and compared with a nonexercising control group. Methods and Results Participants with peripheral artery disease were randomized to: home-based walking exercise that induced ischemic leg symptoms; home-based walking exercise conducted without ischemic leg symptoms; or a nonexercising control group for 12 months. Outcomes were change of walking velocity over 4 m and change of the Short Physical Performance Battery (0-12, with 12=best) at 6- and 12-month follow-up.

Effect of ketamine on transcranial Doppler Gosling pulsatility index in children undergoing procedural sedation: A pilot study.

Objectives: There has been controversy over whether ketamine affects intracranial pressure (ICP) in children. Transcranial Doppler ultrasound (TCD) is a validated technique used to assess ICP changes noninvasively. Gosling pulsatility index (PI) directly correlates with ICP changes.

Physician perceptions and use of reduced-dose direct oral anticoagulants for extended phase venous thromboembolism treatment.

Background: The direct oral anticoagulants (DOACs), apixaban and rivaroxaban, have been studied for extended-phase treatment of venous thromboembolism (VTE). Yet, scant evidence exists surrounding clinician practice and decision-making regarding dose reduction.

Aims: Report clinician practice and characteristics surrounding dose reduction of DOACs for extended-phase VTE treatment.

Antibiotic and antitussive prescribing among urgent care and emergency department visits for respiratory diagnoses in a large health system.

Objective: Urgent care centers (UCs) commonly evaluate patients with respiratory infections, and patients increasingly prefer UCs to emergency departments (EDs) because of their customer-centric approach. The aim of this study is to describe antibiotic and opioid prescribing among UC and ED visits with respiratory diagnoses.

Methods: This is a cross-sectional study of visits to 7 EDs and 6 UCs in the greater Chicago area.
