It is generally considered that fragment fixation with bone pegs (FFBP) for osteochondritis dissecans (OCD) of the humeral capitellum can be indicated for stages I and II according to the International Cartilage Repair Society (ICRS) classification of OCD and it is difficult to obtain complete bone union for advanced lesions. However, the clinical and radiologic results of FFBP with cancellous bone graft for ICRS-OCD stage III with lateral wall involvement have not been described in detail. Good bone union can be achieved with the lateral wall fragment of the capitellum by FFBP in combination with refreshing the sclerotic surface at the base of the lesion and cancellous bone grafting even in ICRS-OCD stage III lesions.
In total, 10 adolescent baseball players with a diagnosis of OCD, a median age of 13.5 years at the time of surgery, and 26.7 months of postoperative follow-up were included. Preoperative imaging showed that all patients had lesions in the late detached stage and of the lateral-widespread tdiographic and clinical outcomes of FFBP for lateral wall fragments with cancellous bone graft were satisfactory, showing that the indications for this procedure could be extended to ICRS-OCD stage III.
We hypothesize that ulnohumeral joint space distance due to gravity valgus stress may not be related to pain in the medial elbow of the dominant arm in baseball players.
Thirty-one male baseball players were divided into an ulnar collateral ligament (UCL) injury group (n= 16) and a Healthy group (n= 15). The injury groups were diagnosed with UCL injury by magnetic resonance imaging, and was defined as having pain during throwing. The medial elbow of each player's throwing arm was imaged by ultrasonography under valgus stress. The ulnohumeral joint space was measured for horizontal and vertical distances. The examiner added resistance force on the subject in order to produce isometric contraction of the forearm pronator muscles (FPMs). Measurements were taken at rest and at FPM isometric contraction. The Mann-Whitney
test was used to compare data between the dominant and nondominant sides, and between the UCL injury group and the Healthy group.
The horizontal and vertical distance at rest on the dominant side was not significantly different between 2 groups. The vertical distance during contraction of the flexor carpi radialis (FCR), flexor carpi ulnaris (FCU), and pronator teres (PT) muscles was significantly different between the UCL injury group and the Healthy group (
< .05) and was shifted laterally. A shift in the lateral direction indicates an increase in valgus instability.
The dominant side suggested that the space in the ulnohumeral joint space was wider, with or without pain. It was suggested that players with medial elbow pain may have impaired FCR, FCU, and PT function.

Primary repair of chronic distal biceps tendon ruptures may not be possible because of tendon retraction, and there remains no clear consensus on the type of reconstruction technique used. The purpose of this study was to report the clinical outcomes and complication rates following reconstruction of chronic distal biceps tendon ruptures.
A systematic review was performed following PRISMA guidelines. The following databases were searched Embase, MEDLINE, and Cochrane Central Register of Controlled Trials. The primary outcomes of interest included range of motion, strength, and functional outcome scores. Secondary outcomes included complication, reoperation, and revision rates. Outcomes and complication rates of each graft type and fixation technique were aggregated and compared with nonparametric Wilcoxon signed rank and rank sum tests. Spearman rank coefficients were calculated for time from injury to surgery on all outcomes.
There were no significant differences found between the graft type or fixatio weave cohorts; more than half of the complications related to the use of autograft were associated with donor site morbidity. No specific graft type was identified as superior, although this may be due to the small patient numbers included within this study.
Distal humerus fracture open reduction and internal fixation (ORIF) represents a substantial cost burden to the health care system. The purpose of this study was to describe surgical encounter cost variation for distal humerus ORIF, and to determine demographic-, injury-, and treatment-specific factors that influence cost.
We retrospectively identified adult patients (≥18 years) treated for isolated distal humerus fractures between July 2014 and July 2019 at a single tertiary academic referral center. For each case, surgical encounter total direct costs (SETDCs) were obtained via our institution's information technology value tools, which prospectively record granular direct cost data for every health care encounter. Costs were converted to 2019 dollars using the personal consumption expenditure indices for health and summarized with descriptive statistics. Univariate and multivariate linear regression models were used to identify factors influencing SETDC.
Surgical costs varied widely for the 47 includr as it is confounded by fracture severity and operative time, this may suggest that surgeons should try to use an olecranon osteotomy judiciously. Although complexity of the fracture pattern was statistically insignificant, it is confounded by the need for an olecranon osteotomy and increased surgical time and likely is a clinically relevant and nonmodifiable driver of surgical cost. These findings highlight opportunities to reduce cost variation, and potentially improve the value of care, for distal humerus ORIF patients.
Understanding mid-term kinetics of immunity to SARS-CoV-2 is the cornerstone for public health control of the pandemic and vaccine development. However, current evidence is rather based on limited measurements, losing sight of the temporal pattern of these changes.
We conducted a longitudinal analysis on a prospective cohort of COVID-19 patients followed up for >6months. Neutralizing activity was evaluated using HIV reporter pseudoviruses expressing SARS-CoV-2S protein. IgG antibody titer was evaluated by ELISA against the S2 subunit, the receptor binding domain (RBD), and the nucleoprotein (NP). Statistical analyses were carried out using mixed-effects models.
We found that individuals with mild or asymptomatic infection experienced an insignificant decay in neutralizing activity, which persisted 6months after symptom onset or diagnosis. Hospitalized individuals showed higher neutralizing titers, which decreased following a 2-phase pattern, with an initial rapid decline that significantly slowed after day 80. Despite this initial decay, neutralizing activity at 6months remained higher among hospitalized individuals compared to mild symptomatic. The slow decline in neutralizing activity at mid-term contrasted with the steep slope of anti-RBD, S2, or NP antibody titers, all of them showing a constant decline over the follow-up period.
Our results reinforce the hypothesis that the quality of the neutralizing immune response against SARS-CoV-2 evolves over the post-convalescent stage.

The coronavirus disease (COVID-19) pandemic may have negatively affected bystander interventions, emergency medical service (EMS) personnel activities, and patient outcomes after out-of-hospital cardiac arrest (OHCA). This study assessed bystander interventions, EMS activities, and patient outcomes during the COVID-19 pandemic era and compared them with those during the non-COVID-19 pandemic era in Osaka City, Japan, where public-access automated external defibrillators (AEDs) are well established.
We conducted this population-based cohort study that included all cases with non-traumatic OHCA treated by EMS personnel and excluded cases with no resuscitation attempt, traumatic cases, cases occurring in healthcare facilities, or cases witnessed by EMS personnel. Data were compared between the COVID-19 pandemic period (February 1, 2020 to July 31, 2020) and the non-COVID-19 pandemic period (February 1, 2019 to July 31, 2019).
During the study periods, 1687 patients were eligible for analyses (COVID-19 n = 825; non-COVID-19 n = 862). Pemigatinib cell line Patients with OHCA during the COVID-19 pandemic period were significantly less likely to receive bystander cardiopulmonary resuscitation (CPR) (COVID-19 33.0%; non-COVID-19 41.3%; p < 0.001) and public-access AED pad application (COVID-19 2.9%; non-COVID-19 6.1%; p = 0.002) compared with patients during the non-COVID-19 pandemic period. There were no significant differences in 1-month survival with favorable neurological outcomes between the two periods (COVID-19 4.6%; non-COVID-19 6.1%; p = 0.196).
The COVID-19 pandemic period did not affect patient outcomes after OHCA but changed bystander behaviors in Osaka City, Japan.

Previous studies showed the benefit of canonical transient receptor potential 6 (TRPC6) channel deficiency in promoting endothelial healing of arterial injuries in hypercholesterolemic animals. Long-term studies utilizing a carotid wire-injury model were undertaken in wild-type (WT) and TRPC6
mice to determine the effects of TRPC6 on phenotypic modulation of vascular smooth muscle cells (SMC) and neointimal hyperplasia. We hypothesized that TRPC6 was essential in the maintenance or reexpression of a differentiated SMC phenotype and minimized luminal stenosis following arterial injury.
The common carotid arteries (CCA) of WT and TRPC6
mice were evaluated at baseline and 4 weeks after wire injury. At baseline, CCA of TRPC6
mice had reduced staining of MYH11 and SM22, fewer elastin lamina, luminal dilation, and wall thinning. After carotid wire injury, TRPC6
mice developed significantly more pronounced luminal stenosis compared with WT mice. Injured TRPC6
CCA demonstrated increased medial/intimal c modulation may lead to mechanism-based therapies for attenuation of IH.
These results suggest that TRPC6 contributes to the restoration or maintenance of arterial SMC contractile phenotype following injury. Understanding the role of TRPC6 in phenotypic modulation may lead to mechanism-based therapies for attenuation of IH.
To identify novel transcriptomic changes to eutopic endometrium by exposure to chronic mild hypernadrogenemia (testosterone [T]) with/without exposure to an obesogenic Western-style diet (WSD).
Two-by-two factorial arrangement of treatments.
National primate research center.
Rhesus macaque females were chronically exposed to T and/or consumed a WSD from menarche through adulthood. After 4.5 years of treatment, Tru-Cut endometrial biopsies were obtained at the midsecretory phase (n = 6-4/group), and paired-end sequencing of RNA was performed. Several females in the T, WSD, and T+WSD cohorts developed endometriosis within 6 months of biopsy; a separate analysis was performed contrasting diagnosis of endometriosis stage 0-2 versus stages 3 and 4 (American Society for Reproductive Medicine revised criteria).
Chronic exposure to mild elevation of T (~five-fold elevation) and/or WSD from menarche until adulthood.
Limma voom empirical Bayes pipeline was performed to detect differentially expressed RNAs (DEs) significantly impacted by treatments and endometriosis severity.
