Short-term adverse event rates and risk factors following total elbow arthroplasty for fracture and arthropathy: a matched analysis of nationally representative data.

Background: Total elbow arthroplasty (TEA) is a mainstay treatment for elbow arthropathy and elbow fracture that can relieve pain and restore functional motion. The purpose of this study was to determine the role of surgical indication in the incidence of short-term adverse events and risk factors influencing complications in TEA to treat arthropathy compared to TEA for fracture. Matched cohorts were created to better isolate the impact of the surgical indication.

Setting: controlled laboratory.

Female Sex, Older Age, Earlier Surgery, Anticoagulant Use, and Meniscal Repair Are Associated With Increased Risk of Manipulation Under Anesthesia or Lysis of Adhesions for Arthrofibrosis After Anterior Cruciate Ligament Reconstruction: A Systematic Review.

Purpose: To determine what patient or surgical factors are associated with an increased risk of arthrofibrosis requiring manipulation under anesthesia (MUA) or lysis of adhesions (LOA) after anterior cruciate ligament reconstruction (ACLR).

Methods: A systematic review was performed in adherence to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Cochrane, Embase, and Medline databases were searched for studies published through February 2023.

Knee extensor torque-velocity relationships following anterior cruciate ligament reconstruction.

Background: The inherent nature of the torque-velocity relationship is the inverse nature between the velocity of muscle contraction and torque production and is an indication of muscle function. The purpose of this study was to characterize the torque-velocity relationship in the quadriceps following anterior cruciate ligament reconstruction compared to healthy limbs.

Methods: 681 participants were included, 493 of which were patients at least four months following anterior cruciate ligament reconstruction (23.

Hip Strength Recovery After Anterior Cruciate Ligament Reconstruction.

Background: Return-to-play (RTP) assessment after anterior cruciate ligament reconstruction (ACLR) rarely includes hip strength.

Hypothesis: It was hypothesized that (1) patients after ACLR will have weaker hip abduction (AB) and adduction (AD) strength compared with the contralateral limb, with larger deficits in women, (2) there will be a correlation between hip and thigh strength ratios and patient-reported outcomes (PROs), and (3) hip AB and AD strength will improve over time.

Study Design: Descriptive laboratory study.

Acute Kidney Injury: Iterative Development of an Audit Tool for Trauma Patients.

Background: Acute kidney injury is a low-volume, high-risk complication in trauma patients and is associated with prolonged hospital length of stay and increased mortality. Yet, no audit tools exist to evaluate acute kidney injury in trauma patients.

Objective: This study aimed to describe the iterative development of an audit tool to evaluate acute kidney injury following trauma.

Age-, Sex-, and Graft-Specific Reference Values From 783 Adolescent Patients at 5 to 7 Months After ACL Reconstruction: IKDC, Pedi-IKDC, KOOS, ACL-RSI, Single-Leg Hop, and Thigh Strength.

To describe age-, sex-, and graft source-specific reference values for patient-reported, physical function, and strength outcome measures in adolescents at 5 to 7 months after anterior cruciate ligament reconstruction. Cross-sectional study. Data were collected at 3 universities and 2 children's hospitals.

Localized Spin Dimers and Structural Distortions in the Hexagonal Perovskite BaCaMoO.

Extended solid-state materials based on the hexagonal perovskite framework are typified by close competition between localized magnetic interactions and quasi-molecular electronic states. Here, we report the structural and magnetic properties of the new six-layer hexagonal perovskite BaCaMoO. Neutron diffraction experiments, combined with magnetic susceptibility measurements, show that the MoO dimers retain localized character down to 5 K and adopt nonmagnetic spin-singlet ground states.

Rectal Injury After Foreign Body Insertion: Secondary Analysis From the AAST Contemporary Management of Rectal Injuries Study Group.

Background: Retained rectal foreign bodies are a common but incompletely studied problem. This study defined the epidemiology, injury severity, and outcomes after rectal injuries following foreign body insertion.

Methods: Twenty-two level I trauma centers retrospectively identified all patients sustaining a rectal injury in this AAST multi-institutional trial (2005-2014).

Concomitant bladder and rectal injuries: Results from the American Association for the Surgery of Trauma Multicenter Rectal Injury Study Group.

Background: Combined traumatic injuries to the rectum and bladder are rare. We hypothesized that the combination of bladder and rectal injures would have worse outcomes than rectal injury alone.

Methods: This is an American Association for the Surgery of Trauma multi-institutional retrospective study from 2004 to 2015 traumatic rectal injury patients who were admitted to one of 22 participating centers.

Is the incorporation of the newborn examination in the pre-registration curriculum acceptable in clinical practice? A qualitative study.

The objectives of this qualitative study were to describe the experiences of currently practicing newborn examiner midwives who had accessed their training post registration; explore their views on the inclusion of newborn examination in the pre-registration curriculum and invite them to identify strategies to achieve practical implementation of the inclusion of the newborn examination in pre-registration in the practice setting. Data were collected through semi-structured interviews and analysed using Thematic Analysis with an inductive approach. Three main themes were identified; experiences of the role, views of the newborn examination being incorporated into the pre-registration midwifery curriculum and practical considerations.

Aminoacidemia following ingestion of native whey protein, micellar casein, and a whey-casein blend in young men.

We examined the aminoacidemic, glycemic, and insulinemic responses following ingestion of 25 g of native whey protein, micellar casein, and a 1:1 blend of whey and casein in randomized order in young adult men. Blood samples were drawn at baseline and at regular intervals for 6 h following ingestion. Area under curve and peak plasma essential amino acid concentrations after the ingestion of the protein blend were similar to whey and greater compared with casein.

Bacterial Burden in Critically Injured Ventilated Patients Does Not Correlate with Progression to Pneumonia.

Background: Ventilator-associated pneumonia (VAP) is common in critically injured patients. The pathogenesis of VAP is not completely understood. We hypothesized that mechanically ventilated trauma patients who develop pneumonia have a progressive increase in pathogen burden over the course of ventilation until a threshold for symptomatic pneumonia is reached, leading to clinical suspicion of VAP.

Contemporary management of rectal injuries at Level I trauma centers: The results of an American Association for the Surgery of Trauma multi-institutional study.

Introduction: Rectal injuries have been historically treated with a combination of modalities including direct repair, resection, proximal diversion, presacral drainage, and distal rectal washout. We hypothesized that intraperitoneal rectal injuries may be selectively managed without diversion and the addition of distal rectal washout and presacral drainage in the management of extraperitoneal injuries are not beneficial.

Methods: This is an American Association for the Surgery of Trauma multi-institutional retrospective study from 2004 to 2015 of all patients who sustained a traumatic rectal injury and were admitted to one of the 22 participating centers.

Factors influencing the sustainability of volunteer peer support for breast-feeding mothers within a hospital environment: An exploratory qualitative study.

Objectives: the objectives of this study were to explore breast feeding peer supporters' motivation to volunteer within a hospital environment, to describe their experiences of volunteering within a hospital environment, to examine the relationships between peer supporters and ward staff, and to identify factors contributing to the future sustainability of the service.

Design: a qualitative study; peer supporters and clinical ward staff were interviewed using a semi-structured schedule and data were analysed using Thematic Analysis with an inductive approach.

Setting And Participants: six peer supporters and ten ward staff, whose role included giving breast feeding support, working on a maternity ward in one consultant-led unit in England that had been hosting breast feeding peer support volunteers for the previous three years.

Measurement of cord insulin and insulin-related peptides suggests that girls are more insulin resistant than boys at birth.

Objective: We aimed to examine sex differences in insulin and insulin propeptide concentrations at birth using validated cord blood collection.

Research Design And Methods: We tested the impact on insulin and insulin propeptides of taking 13 cord blood samples in heparin and EDTA and then centrifuging and separating plasma after 1, 2, 24, or 48 h at room temperature (heparin) or 4 degrees C (EDTA). Cord plasma insulin and insulin propeptides concentrations were measured in 440 babies and correlated with offspring anthropometry measured at birth.

1,25-Dihydroxyvitamin D3/VDR-mediated induction of FGF23 as well as transcriptional control of other bone anabolic and catabolic genes that orchestrate the regulation of phosphate and calcium mineral metabolism.

1,25-Dihydroxyvitamin D(3) (1,25D) is known primarily as a regulator of calcium, but 1,25D also promotes phosphate absorption from intestine, reabsorption from kidney, and bone mineral resorption. FGF23 is a newly discovered phosphaturic hormone that, like PTH, lowers serum phosphate by inhibiting renal reabsorption via Npt2a. We show that 1,25D strongly upregulates FGF23 in bone.

Effect of prepubertal body weight gain and breed on carcass composition at puberty in beef heifers.

Fourteen prepubertal Angus heifers, all of which reached puberty, and 11 Santa Gertrudis (SG) heifers, eight of which reached puberty, were divided into two treatment groups. There was no breed difference in age at puberty for those that reached puberty. Treatment 1 (T1) heifers, fed to gain .
