Serial capture affinity purification (SCAP) is a powerful method to isolate a specific protein complex. When combined with cross-linking mass spectrometry and computational approaches, one can build an integrated structural model of the isolated complex. Here, we applied SCAP to dissect a subpopulation of WDR76 in complex with SPIN1, a histone reader that recognizes trimethylated histone H3 lysine4 (H3K4me3).

Objectives: Percutaneous vertebroplasty and kyphoplasty are common interventions for osteoporotic vertebral compression fractures. However, there is concern about an increased risk of adjacent-level fractures after treatment. This study aimed to compare the risk of adjacent-level fractures after vertebroplasty and kyphoplasty with the natural history after osteoporotic vertebral compression fractures.

The experience of menopause is not "one size fits all." Instead, biologic, physiologic, and sociocultural factors strongly affect women's experiences of menopause symptoms and the ways in which they would like to manage their care. By providing culturally sensitive and patient-centered care, clinicians may be able to improve menopause experiences for all of their patients.

Quality and process improvement (QI/PI) in children's surgical care require reliable data across the care continuum. Since 2012, the American College of Surgeons' (ACS) National Surgical Quality Improvement Program-Pediatric (NSQIP-Pediatric) has supported QI/PI by providing participating hospitals with risk-adjusted, comparative data regarding postoperative outcomes for multiple surgical specialties. To advance this goal over the past decade, iterative changes have been introduced to case inclusion and data collection, analysis and reporting.

Purpose: To evaluate the effect of general anesthesia on right atrial (RA) pressure measurements during transjugular intrahepatic portosystemic shunt (TIPS) placement using propensity score match analysis.
Materials: A single-institution database was used to identify 664 patients who underwent TIPS creation under either conscious sedation (CS) or general anesthesia (GA) between 2009 and 2018. A propensity-matched cohort was created using logistic regression of sedation method on demographics, liver disease status, and indications.

Background: The objective of this study was to quantify prophylaxis misutilization to identify high-priority procedures for improved stewardship and SSI prevention.
Methods: This was a multicenter analysis including 90 hospitals participating in the NSQIP-Pediatric Antibiotic Prophylaxis Collaborative from 6/2019 to 6/2020. Prophylaxis data were collected from all hospitals and misutilization measures were developed from consensus guidelines.

The effectiveness and safety of direct oral anticoagulants (DOAC) compared with warfarin remains uncertain in obese patients. We assessed the comparative effectiveness and safety of DOACs with warfarin for the treatment of VTE among obese patients. This multi-center retrospective cohort study included adults with a BMI ≥ 35 kg/m or weight ≥ 120 kg prescribed either DOAC (apixaban, dabigatran, edoxaban, rivaroxaban) or warfarin for a VTE diagnosis.

Background: The subdermal application of energy using a helium-based plasma radiofrequency (RF) device has been shown to improve skin laxity. Helium-based plasma RF technology (Renuvion; Apyx Medical, Clearwater, FL) utilizes RF to ionize helium into an electrically conductive plasma capable of coagulating and contracting soft tissue with high precision and minimal thermal spread. This study provides information on the early use of the new generation of electrosurgical generator (APYX-RS3) containing a feature that allows for quantification of the amount of energy delivered to tissue during treatments.

Introduction: While the Dominantly Inherited Alzheimer Network Trials Unit (DIAN-TU) was ongoing, external data suggested higher doses were needed to achieve targeted effects; therefore, doses of gantenerumab were increased 5-fold, and solanezumab was increased 4-fold. We evaluated to what extent mid-trial dose increases produced a dose-dependent treatment effect.
Methods: Using generalized linear mixed effects (LME) models, we estimated the annual low- and high-dose treatment effects in clinical, cognitive, and biomarker outcomes.

Background: Sim Wars is a simulation-based competition wherein teams of medical trainees are presented a clinical scenario and provide patient care in front of a live audience. This non-traditional educational offering is a form of serious games in medical education and allows for experiential learning via direct observation. Although a well-described educational modality within graduate medical education, there is a dearth of literature regarding Sim Wars as an educational tool within undergraduate medical education.

Importance: Use of postoperative antimicrobial prophylaxis is common in pediatric surgery despite consensus guidelines recommending discontinuation following incision closure. The association between postoperative prophylaxis use and surgical site infection (SSI) in children undergoing surgical procedures remains poorly characterized.
Objective: To evaluate whether use of postoperative surgical prophylaxis is correlated with SSI rates in children undergoing nonemergent surgery.

Venous (VTE) and arterial (ATE) thromboemboli are a leading cause of morbidity and mortality in patients with cancer. Patients with hematological malignancies are at an exceptionally high risk of both VTE and ATE. This risk varies based on patient- and disease-specific risk factors and can be predicted using risk prediction models for some types of hematological malignancies.

Purpose: To evaluate the technical success and clinical outcomes of thoracic duct embolization (TDE) using transabdominal antegrade and transcervical retrograde accesses to treat patients with chyle leak.
Materials And Methods: This study was a retrospective, nonblinded, single-institution chart review of all patients aged 18 years or older over a 6-year time frame who underwent lymphangiography with attempted TDE for iatrogenic or spontaneous chyle leaks using transabdominal antegrade and/or transcervical retrograde accesses.
Results: Ninety-nine patients underwent 113 procedures.

Objective: To establish surgical site infection (SSI) performance benchmarks in pediatric surgery and to develop a prioritization framework for SSI prevention based on procedure-level SSI burden.
Background: Contemporary epidemiology of SSI rates and event burden in elective pediatric surgery remain poorly characterized.
Methods: Multicenter analysis using sampled SSI data from 90 hospitals participating in NSQIP-Pediatric and procedural volume data from the Pediatric Health Information System (PHIS) database.

Recent work identified single time points ("events") of high regional cofluctuation in functional Magnetic Resonance Imaging (fMRI) which contain more large-scale brain network information than other, low cofluctuation time points. This suggested that events might be a discrete, temporally sparse signal which drives functional connectivity (FC) over the timeseries. However, a different, not yet explored possibility is that network information differences between time points are driven by sampling variability on a constant, static, noisy signal.

Introduction And Hypothesis: Our primary aim was to describe the incidence of the diagnosis of urosepsis or pyelonephritis during the 60 days following initial evaluation of an uncomplicated urinary tract infection (UTI) among female Medicare beneficiaries ≥ 65 years of age.
Study Design: This was a retrospective cohort study of women ≥ 65 years of age undergoing evaluation for an incident, uncomplicated urinary tract infection (UTI) between the years 2011-2018 included in the Medicare 5% Limited Data Set (LDS). We grouped women into age categories of 65-74 years, 75-84 years, or > 84 years old.
