In patients with symptomatic femoroacetabular impingement syndrome, bilateral hip pain has been reported to occur in high frequency. However, not all patients require bilateral hip arthroscopy.

To determine the incidence, patient-specific variables, and postoperative outcomes in patients who presented with bilateral hip pain at the time of index hip arthroscopy and underwent subsequent contralateral arthroscopic hip surgery.

Case series; Level of evidence, 4.

Patients who presented with bilateral hip pain, underwent primary hip arthroscopy between January 2012 and June 2018 for indication of femoroacetabular impingement syndrome, and had minimum 2-year follow-up were retrospectively analyzed. Baseline descriptive data, preoperative hip range of motion, and radiographic measurements were recorded with pre- and postoperative patient-reported outcomes (PROs). Independent samples
test was used to compare continuous variables, and chi-square test was used to compare categorical variables between patientents undergoing bilateral surgery reported significantly improvement in PROs at minimum 2-year follow-up.Vaccination coverage in the Federation of Bosnia and Herzegovina, in Bosnia and Herzegovina, has been declining since 2014. This qualitative study aimed to identify barriers and drivers to childhood vaccination for parents. The COM-B (capability-opportunity-motivation-behavior) model was the underpinning theoretical framework. Face-to-face interviews with 22 parents of fully (n = 6), delayed/partially vaccinated (n = 9) and unvaccinated (n = 7) children were conducted. Interviews explored individual factors (capability-knowledge and skills; motivation-attitudes, confidence and trust) and context factors (physical opportunity-information, access, health systems; and social opportunity - social support, norms). Data were analyzed in NVivo using content analysis exploring differences in COM factors by vaccination status and location. Parents of fully vaccinated children typically reported individual and context drivers to vaccination. They accepted vaccination, trusted health workers, and were content with services. Parents of delayed/partially vaccinated children fell into two subgroups (1) Those who accepted vaccination and attributed delays to their organizational skills or frustration with appointment times. (2) Those fitting the profile of "vaccine hesitant" - generally valuing vaccination and health worker advice, yet with concerns often triggered by media/social media. Parents of unvaccinated children mentioned individual and context barriers to vaccination, notably significant concerns about safety, some distrust of health workers and resentment of mandatory vaccination. Urban/rural differences included urban parents being more likely to report experiences with vaccine shortages and very few had received information leaflets. The study identified complex and inter-related barriers and drivers to parents' childhood vaccination behaviors. These insights have informed the development of tailored interventions to improve coverage.Objective To examine the efficacy, safety, and tolerability of methylphenidate extended-release orally disintegrating tablets (MPH XR-ODT) for the treatment of attention-deficit/hyperactivity disorder (ADHD) during the open-label dose-optimization/stabilization period of a phase 3 laboratory classroom study. Methods Children (6-12 years) diagnosed with ADHD were enrolled. Treatment was initiated with MPH XR-ODT 20 mg daily. Doses were adjusted weekly by 10-20 mg during the 4-week dose-optimization period (visits 2-5) until an optimal dose was reached. The optimal dose was sustained during a 1-week stabilization period (visits 6-7). Efficacy was assessed using the ADHD Rating Scale-IV (ADHD-RS-IV) score and the Clinical Global Impression-Improvement (CGI-I) score. Adverse events (AEs) were recorded throughout the study. A secondary subgroup analysis by baseline ADHD-RS-IV score, sex, age, and weight was also performed. Results The mean (standard deviation [SD]) final optimized MPH XR-ODT daily dose was 41.8 (14.6) mg and ranged from 20 to 60 mg. Final optimized dose was higher for children with more severe baseline ADHD-RS-IV total scores. ADHD-RS-IV total scores decreased progressively during dose optimization, with a mean (SD) change from baseline at visit 7 of -21.4 (8.9). CGI-I scores shifted from "minimally improved" (mean [SD] 3.1 [1.1]) at visit 3 to "much improved" (1.6 [0.6]) at visit 7. Baseline ADHD-RS-IV total score was highest for participants optimized to 40 mg (mean [standard error] 40.0 [1.4]) and lowest for those optimized to 20 mg (34.8 [2.1]). By visit 6, mean ADHD-RS-IV score was comparable for all optimized dose groups. Common treatment-emergent AEs (≥5% of participants) included decreased appetite, upper abdominal pain, headaches, and insomnia. Conclusions Dose optimization of MPH XR-ODT led to a reduction in ADHD symptoms, indicated by a decrease in ADHD-RS-IV and CGI-I scores. AEs were consistent with those of other MPH products.

Although critical bone loss for anterior instability is well defined, a clinically significant threshold of posterior bone loss has not been elucidated.

Patients with failed arthroscopic posterior shoulder capsulolabral repair will have increased posterior glenoid bone loss with a defined critical threshold.

Case control study; Level of evidence, 3.

Athletes older than 18 years with unidirectional posterior instability treated with arthroscopic repair were evaluated at 2-year minimum follow-up. Failure was defined as revision surgery, American Shoulder and Elbow Surgeons (ASES) score of <60, or subjective stability score of >5. Magnetic resonance imaging (MRI) measurements from 19 patients with failed arthroscopic posterior shoulder capsulolabral repair were compared with 56 patients whose surgery was successful. MRI measures included glenoid version, labral version, glenoid width, labral width, percentage bone loss using the circle technique, labral height, percent subluxation, and recently des10 times higher surgical failure rate, while a threshold of 15% led to a 25 times higher surgical failure rate. Surgical failure of posterior capsulolabral repair, however, is relatively rare as it is an overall successful intervention.
Risk factors for failure of arthroscopic posterior shoulder capsulolabral repair include smaller glenoid bone width and greater percentage of glenoid bone loss. A threshold of 11% posterior glenoid bone loss implicated a 10 times higher surgical failure rate, while a threshold of 15% led to a 25 times higher surgical failure rate. Surgical failure of posterior capsulolabral repair, however, is relatively rare as it is an overall successful intervention.
Tendons heal by fibrotic repair, increasing the likelihood of reinjury. Animal tendon injury and overuse models have identified transforming growth factor beta (TGF-β) and bone morphogenetic proteins (BMPs) as growth factors actively involved in the development of fibrosis, by mediating extracellular matrix synthesis and cell differentiation.

To understand how TGF-β and BMPs contribute to fibrotic processes using tendon-derived cells isolated from healthy and diseased human tendons.

Controlled laboratory study.

Tendon-derived cells were isolated from patients with a chronic rotator cuff tendon tear (large to massive, diseased) and healthy hamstring tendons of patients undergoing anterior cruciate ligament repair. Isolated cells were incubated with TGF-β1 (10 ng/mL) or BMP-2 (100 ng/mL) for 3 days. Gene expression was measured by real-time quantitative polymerase chain reaction. Cell signaling pathway activation was determined by Western blotting.

TGF-β1 treatment induced
mRNA expression in both cis study suggest that diseased tendon-derived cells respond differently than healthy cells in the presence of TGF-β1 and BMP-2. The altered responses of diseased cells may influence fibrotic repair processes during tendon healing.Objective Although peer difficulties and sluggish cognitive tempo (SCT) are related, studies have yet to examine environmental factors that may advance further understanding of this association. The current study tested whether peer difficulties, specifically social competence and peer victimization, interacted with school support, a component of school climate, in relation to adolescents' SCT symptoms. Further, we explored whether these relations would be differentially associated with SCT in adolescents with and without attention-deficit/hyperactivity disorder (ADHD).Method Adolescents (N = 288; Mage = 14.08, 45% female, 82.6% White; 52% with ADHD) completed measures of social competence, peer victimization, school climate support, and SCT and ADHD inattentive (IN) symptoms. Parents also reported on adolescents' social competence, SCT, and ADHD-IN symptoms.Results Results indicated that adolescent and parent ratings of lower social competence were both associated with higher adolescent-reported SCT symptoms in the context of low, but not high, school support. Relational and nonphysical victimization were associated with higher self-reported SCT symptoms in the context of low school support. Lower adolescent- and parent-reported social competence were also related to higher parent-reported SCT symptoms, with these associations not moderated by school support. These results remained after controlling for demographics and ADHD-IN symptoms and were similar across adolescents with and without ADHD.Conclusions Findings from the current study are the first to provide evidence that peer difficulties and school climate are jointly related to adolescents' self-reported SCT and underscore the importance of continued research investigating social adversity and environmental factors in relation to SCT.
Femoroacetabular impingement (FAI) is a major cause of hip pain in young adults and athletes. Surgical treatment of FAI is recommended in cases of failed nonoperative treatment that have the typical clinical and radiographic findings. At present, the role of risk factors for revision surgery and progression to total hip arthroplasty (THA) in patients with FAI is still unclear.

To investigate the possible association between (1) rate of revision and progression to THA and (2) patient characteristics, type of lesion, family history of hip disease, type of intervention, radiographic parameters, physical examination, and pre- and postoperative scores.

Systematic review; Level of evidence, 4.

The present systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. In October 2020, the main online databases were accessed. All articles concerning surgical correction for selected patients with FAI were accessed. Patient characteristics, type of intervention, radiographic parameters, physical examination, and pre- and postoperative scores were assessed.
