In addition, we showed that A33D and A259T were biased receptors and defect in constitutive activation of ERK1/2 signaling through MC3R might be a cause for morbid obesity. Our sequencing and co-segregation studies combined with comprehensive functional analysis demonstrated that A259T might be predisposing to obesity. Further investigations in larger cohorts will be needed in order to define this association and the specific phenotypic characteristics resulting from these mutations.

To assess complications of hip endoscopy in patients with subgluteal space pathologies.

This was a retrospective study of patients diagnosed with sciatic nerve entrapment (SNE), ischiofemoral impingement (IFI), and rupture of the proximal origin of the hamstring muscles (RHM) who underwent a hip endoscopy from January 2012 to December 2018, after a minimum of 3 months of conservative management without satisfactory results. Complications were documented and graded using the adapted system of Clavien-Dindo. Revision surgeries were classified as treatment failures. Function was evaluated by the Western Ontario McMaster Universities Osteoarthritis Index before and 12 months after the surgical procedure.

A total of 97 hips with subgluteal space pathologies were treated with hip endoscopy. This total consisted of 77 hips with SNE, 5 with IFI, 12 with SNE+ IFI, and 3 hips with RHM. Minor (Clavien-Dindo I-II) and major (Clavien-Dindo III-V) complications occurred in 7.22% (7) (95% confidence interval 3.54%-14.15%) and 12.37% (12) (95% confidence interval 7.22%-20.39%). Grade II, III, and IV complications were reported in 7.22% (7), 7.22%, and 5.15% (5) hips, respectively. Temporary nerve injury of the sciatic nerve, hematoma, and permanent nerve injury of the posterior femoral cutaneous nerve were the most common grade II, grade III, and grade IV complications, respectively. The revision rate was 6.19% (6) and entrapment of the sciatic nerve was the main cause of reoperation. No statistically significant differences were found between cases with and without complications in the Western Ontario McMaster Universities Osteoarthritis Index scores evaluated before and after surgery (P > .05).

A high rate of complications associated with hip endoscopy were observed in patients with SNE, IFI, and RHM. Sciatic nerve and posterior femoral cutaneous nerve injury were the most frequent events.

The purpose of this study was to compare the outcome of cartilage regeneration between bone marrow aspirate concentrate (BMAC) augmentation and allogeneic human umbilical cord blood-derived mesenchymal stem cell (hUCB-MSCs) transplantation in high tibial osteotomy (HTO) with microfracture (MFX) for medial unicompartmental osteoarthritis (OA) of the knee in the young and active patient.

Between January 2015 and December 2019, the patients who underwent HTO and arthroscopy with MFX combined with BMAC or allogeneic hUCB-MSCs procedure for medial unicompartmental OA with kissing lesion, which was shown full-thickness cartilage defect (≥ International Cartilage Repair Society [ICRS] grade 3B) in medial femoral cartilage and medial tibial cartilage, were include in this study. Retrospectively we compared clinical outcomes, including Hospital for Special Surgery score, Knee Society Score (KSS) pain and function, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score between BMAC and hUCen though the clinical outcomes improved regardless of which treatment was administered.

To investigate patients with generalized joint laxity (GJL) after primary anterior cruciate ligament reconstruction (ACLR) as to the risk of ACLR failure, graft selection success rates, and overall clinical outcomes.

A systematic review of the PubMed and EMBASE databases was performed to identify studies published from the inception of the databases through February 4, 2020. The inclusion criteria were original studies written in English involving outcomes of patients with GJL who had undergone primary ACLR.

Nine studies met the inclusion criteria, which included 1,869 patients. selleck chemical Most underwent isolated bone-patellar tendon-bone (BPTB; n= 1062) or hamstring autograft (n= 696) ACLR. Overall, higher graft failure rates tended to occur in patients with GJL compared with patients without GJL (range per study 6%-30% vs 0%-12.3%). Inferior results were also found patients with GJL in patient-reported outcome measures and postoperative knee stability determined by KT, Lachman, and pivot-shift tests. BPTB autografts tended to have lower failure rates than hamstring autografts in patients with GJL (range per study 6%-21% vs 17.6%-30%). Only 1 study determined outcomes of a combined ACLR and extra-articular augmentation in patients with GJL.

Patients with GJL are at an increased risk of inferior outcomes and graft failure after primary ACLR. BPTB autografts may have more favorable stability outcomes compared with hamstring autografts in patients with GJL. However, the reported stability parameters and KT results, even with a BPTB autograft, remain inferior to non-GJL published results, and the added benefit of an extra-articular procedure to supplement the primary ACLR deserves consideration.

To appraise the available animal and human studies investigating low-intensity pulsed ultrasound stimulation (LIPUS) on tendon, ligament, and bone-soft tissue (B-ST) junction healing.

A systematic review of PUBMED, EMBASE, and the Cochrane Library was performed for animal and human studies investigating the effects of LIPUS on tendon, ligament, and B-ST junction healing. The systematic search was performed using the key term "low intensity pulsed ultrasound" and any of the following "tendon," "ligament," "tendon-bone," and "bone-tendon." Inclusion criteria consisted of (1) randomized controlled trials assessing the effect of LIPUS on bone, tendon, and soft tissue in animals or humans and (2) English-language articles.

A total of 28 animal and 2 human studies met inclusion criteria. Animal studies utilized various models, including Achilles and patellar tendon transections, medial collateral ligament transections, and surgical repair of patellar tendon, rotator cuff tendon, and anterior cruciate ligament, to evaluate the effects of LIPUS.
