Feasibility of Alerting Systems and Family Care Partner Support for Postoperative Delirium Prevention.

Background: The objective of this study was to determine whether postoperative pager alerts to the Hospital Elder Life Program (HELP), a delirium prevention service, would accelerate program enrollment for older surgical patients. This study also tested feasibility of family care partner interventions for delirium prevention.

Methods: This single-center, pilot clinical trial factorially randomized 57 non-cardiac surgical patients ≥70 years of age to 4 arms: (1) standard care, (2) pager alerts to accelerate HELP enrollment, (3) family care partner-based delirium prevention interventions, or (4) a combined arm with both HELP and family interventions.

Standardised and Reproducible Phenotyping Using Distributed Analytics and Tools in the Data Analysis and Real World Interrogation Network (DARWIN EU).

Purpose: The generation of representative disease phenotypes is important for ensuring the reliability of the findings of observational studies. The aim of this manuscript is to outline a reproducible framework for reliable and traceable phenotype generation based on real world data for use in the Data Analysis and Real-World Interrogation Network (DARWIN EU). We illustrate the use of this framework by generating phenotypes for two diseases: pancreatic cancer and systemic lupus erythematosus (SLE).

Assessment and mitigation of bias in influenza and COVID-19 vaccine effectiveness analyses - IVY Network, September 1, 2022-March 30, 2023.

Background: In test-negative studies of vaccine effectiveness (VE), including patients with co-circulating, vaccine-preventable, respiratory pathogens in the control group for the pathogen of interest can introduce a downward bias on VE estimates.

Methods: A multicenter sentinel surveillance network in the US prospectively enrolled adults hospitalized with acute respiratory illness from September 1, 2022-March 31, 2023. We evaluated bias in estimates of VE against influenza-associated and COVID-19-associated hospitalization based on: inclusion vs exclusion of patients with a co-circulating virus among VE controls; observance of VE against the co-circulating virus (rather than the virus of interest), unadjusted and adjusted for vaccination against the virus of interest; and observance of influenza or COVID-19 against a sham outcome of respiratory syncytial virus (RSV).

Dorsal Translocation of the Flexor Pollicis Longus Tendon Following Pediatric Both Bone Forearm Fracture.

Tendon entrapment is a rare complication of closed forearm fractures. A 16-year-old boy sustained a type 1 open both bone forearm fracture after falling from a skateboard. The injury was initially managed with irrigation, debridement, and flexible intramedullary nailing.

Respiratory Viral Infections from 2015 to 2022 in the HIVE Cohort of American Households: Incidence, illness characteristics, and seasonality.

Background: Viral respiratory illnesses are the most common acute illnesses experienced and generally follow a predicted pattern over time. The SARS-CoV-2 pandemic interrupted that pattern.

Methods: The HIVE (Household Influenza Vaccine Evaluation) study was established in 2010 to follow a cohort of Southeast Michigan households over time.

Pediatric Hand Surgery Training: A Spectrum of Educational Resources.

Treatment of children with upper-extremity trauma, congenital hand differences, cerebral palsy, and brachial plexus birth injuries requires specialized training, given the spectrum of pathology and complexities of treating an individual who is still developing. Although a limited number of dedicated pediatric hand surgery fellowships are available, mastering the large breadth of the field should ideally begin early in training and may take several different pathways. The authors seek to provide a comprehensive list of resources for trainees interested in pediatric hand surgery, including training opportunities, educational tools, and networking organizations.

Vascularized Transfer of Second Metacarpal Base for Treatment of Capitate Osteonecrosis.

Background: Capitate osteonecrosis is a rare condition that mainly presents in young patients with chronic wrist pain. Treatment aims to address pain, arthritic changes, or carpal instability.

Methods: We present the surgical technique and outcomes of using a vascularized pedicled second metacarpal base transferred on the second dorsal metacarpal artery to treat capitate osteonecrosis in a 20-year-old female secretary, former gymnast, and a 25-year-old female student with acute lymphoblastic leukemia.

Intraoperative hypoglycemia among adults with intraoperative glucose measurements: a cross-sectional multicentre retrospective cohort study.

Purpose: Intraoperative hypoglycemia is presumed to be rare, but generalizable multicentre incidence and risk factor data for adult patients are lacking. We used a multicentre registry to characterize adults with intraoperative hypoglycemia and hypothesized that intraoperative insulin administration would be associated with hypoglycemia.

Methods: We conducted a cross-sectional retrospective multicentre cohort study.

Comparative Effectiveness Systematic Review and Meta-analysis of Peripheral Nerve Repair Using Direct Repair and Connector-assisted Repair.

Background: This clinical literature systematic review and meta-analysis were performed to assess differences in outcomes between nerves repaired with direct repair (DR) and connector-assisted repair (CAR).

Methods: A systematic literature review for DR and CAR was performed. Studies from 1980 through August 2023 were included if DR or CAR repairs were performed in upper extremities with nerve gaps less than 5 mm and reported sensory Medical Research Council Classification (MRCC) outcomes or equivalent.

MORC2 phosphorylation fine tunes its DNA compaction activity.

Variants in the poorly characterised oncoprotein, MORC2, a chromatin remodelling ATPase, lead to defects in epigenetic regulation and DNA damage response. The C-terminal domain (CTD) of MORC2, frequently phosphorylated in DNA damage, promotes cancer progression, but its role in chromatin remodelling remains unclear. Here, we report a molecular characterisation of full-length, phosphorylated MORC2, demonstrating its preference for binding open chromatin and functioning as a DNA sliding clamp.

Effectiveness of Updated 2023-2024 (Monovalent XBB.1.5) COVID-19 Vaccination Against SARS-CoV-2 Omicron XBB and BA.2.86/JN.1 Lineage Hospitalization and a Comparison of Clinical Severity - IVY Network, 26 Hospitals, October 18, 2023-March 9, 2024.

Background: Assessing COVID-19 vaccine effectiveness (VE) and severity of SARS-CoV-2 variants can inform public health risk assessments and decisions about vaccine composition. BA.2.

Co-clustering of EphB6 and ephrinB1 in trans restrains cancer cell invasion.

EphB6 is an understudied ephrin receptor tyrosine pseudokinase that is downregulated in multiple types of metastatic cancers. Unlike its kinase-active counterparts which autophosphorylate and transmit signals upon intercellular interaction, little is known about how EphB6 functions in the absence of intrinsic kinase activity. Here, we unveil a molecular mechanism of cell-cell interaction driven by EphB6.

Severity of Respiratory Syncytial Virus vs COVID-19 and Influenza Among Hospitalized US Adults.

Importance: On June 21, 2023, the Centers for Disease Control and Prevention recommended the first respiratory syncytial virus (RSV) vaccines for adults aged 60 years and older using shared clinical decision-making. Understanding the severity of RSV disease in adults can help guide this clinical decision-making.

Objective: To describe disease severity among adults hospitalized with RSV and compare it with the severity of COVID-19 and influenza disease by vaccination status.

Structural differences contributing to sex-specific associations between FN BMD and whole-bone strength for adult White women and men.

Hip areal BMD (aBMD) is widely used to identify individuals with increased fracture risk. Low aBMD indicates low strength, but this association differs by sex with men showing greater strength for a given aBMD than women. To better understand the structural basis giving rise to this sex-specific discrepancy, cadaveric proximal femurs from White female and male donors were imaged using nano-CT and loaded in a sideways fall configuration to assess strength.

Incident Use of Hydroxychloroquine for the Treatment of Rheumatoid Arthritis and Systemic Lupus Erythematosus During the COVID-19 Pandemic.

Objective: We studied whether the use of hydroxychloroquine (HCQ) for COVID-19 resulted in supply shortages for patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE).

Methods: We used US claims data (IQVIA PHARMETRICS® Plus for Academics [PHARMETRICS]) and hospital electronic records from Spain (Institut Municipal d'Assistència Sanitària Information System [IMASIS]) to estimate monthly rates of HCQ use between January 2019 and March 2022, in the general population and in patients with RA and SLE. Methotrexate (MTX) use was estimated as a control.

Developing a clinical decision support system software prototype that assists in the management of patients with self-harm in the emergency department: protocol of the PERMANENS project.

Background: Self-harm presents a significant public health challenge. Emergency departments (EDs) are crucial healthcare settings in managing self-harm, but clinician uncertainty in risk assessment may contribute to ineffective care. Clinical Decision Support Systems (CDSSs) show promise in enhancing care processes, but their effective implementation in self-harm management remains unexplored.

Update on the Selection Criteria of Plastic Surgery Residents: A Survey of Program Directors and Associate Program Directors.

Background: Plastic and reconstructive surgery (PRS) is recognized as a highly competitive specialty. Since the first assessment of resident selection criteria in 2007, PRS residency programs have adopted holistic review processes and adapted to changes such as a decline in medical schools participating in the Alpha Omega Alpha Honor Medical Society as well as the recent transition to pass/fail grading for the United States Medical Licensing Examination (USMLE) step 1 examination (Schultz et al.
