This crosslinker-free method to fabricate CMs resulted in spherical, stable, biocompatible CMs, and could be an excellent technique for multiple tissue engineering applications. © 2020 Wiley Periodicals, Inc.While exome sequencing (ES) is commonly the final diagnostic step in clinical genetics, it may miss diagnoses. To clarify the limitations of ES, we investigated the diagnostic yield of genetic tests beyond ES in our Undiagnosed Diseases Network (UDN) participants. We reviewed the yield of additional genetic testing including genome sequencing (GS), copy number variant (CNV), noncoding variant (NCV), repeat expansion (RE), or methylation testing in UDN cases with nondiagnostic ES results. Overall, 36/54 (67%) of total diagnoses were based on clinical findings and coding variants found by ES and 3/54 (6%) were based on clinical findings only. The remaining 15/54 (28%) required testing beyond ES. Of these, 7/15 (47%) had NCV, 6/15 (40%) CNV, and 2/15 (13%) had a RE or a DNA methylation disorder. Thus 18/54 (33%) of diagnoses were not solved exclusively by ES. Several methods were needed to detect and/or confirm the functional effects of the variants missed by ES, and in some cases by GS. These results indicate that tests to detect elusive variants should be considered after nondiagnostic preliminary steps. Further studies are needed to determine the cost-effectiveness of tests beyond ES that provide diagnoses and insights to possible treatment. © 2020 Wiley Periodicals, Inc.INTRODUCTION Evidence-based guidelines suggest a conservative, nonsurgical approach as first-line treatment for knee osteoarthritis. However, previous literature has documented underutilization of the fundamental components of condition management emphasized in the guidelines. The intervention aim is to apply organized conservative components of care for knee osteoarthritis in an evidence-based management program through the translation of research into practice with a target to observe meaningful functional improvement in a distinct population. METHODS The program, modeled after the nonsurgical arm of a randomized, controlled trial, was designed as a single-arm observational cohort study with a pre- and post-program comparison for participants reporting presence of knee osteoarthritis who were attributed to a specific employer's health plan in the United States. The 12-week intervention consisted of condition education, group exercise, and a dietary intervention. RESULTS Ninety-six participants enrolled in the program, of which 72% completed the protocol. The median change in pre- to post-program Knee Injury and Osteoarthritis Outcome Score values was 10.4 ± 0.8 (Z = 210.5, p less then 0.001)-a clinically important change. Secondary outcomes were complementary to the primary outcome. selleckchem CONCLUSIONS Results of the program indicate that the clinically significant 3-month findings in the report by Skou et al. (2015) regarding functional improvement can be replicated in an alternate setting. Organizing and offering fundamental components of condition management in a group format with provider oversight could be a feasible and logical component in the continuum of care for knee osteoarthritis, while complementing other secondary management strategies following diagnosis. © 2020 John Wiley & Sons, Ltd.Betulin is a lupane type pentacyclic triterpenoid, and commonly found in the bark of birch trees. It displays various pharmacological properties, such as antibacterial, anti-inflammation, antitumor, and antiviral. In this report, we attempted to investigate the anti-proliferative and pro-apoptotic effects of betulin on osteosarcoma cell lines. Our results revealed that betulin significantly decreased cell viability and colony formation in osteosarcoma cell lines. Dose-dependent induction of Annexin V positive cells, activated caspase 8, activated caspase 9, activated caspase 3, and the cleavage of poly (ADP-ribose) polymerase were observed after the treatment with betulin, indicating betulin induces apoptosis in osteosarcoma cell lines. mTOR has been identified as a key modulator of autophagy in response to different stresses. In this study, we found that the treatment with betulin suppressed the activation of mTOR, and increased the level of LC 3-II, the autophagy marker, in osteosarcoma cell lines. Co-administration of the autophagy inhibitor chloroquine significantly rescued the cell viability and the clonogenic activity in betulin-treated osteosarcoma cell lines. Our data showed that betulin induced autophagy, and the up-regulated autophagy positively contributed to the apoptosis. Taken together, our findings suggested that betulin may serve as a promising anti-proliferative agent for treating osteosarcoma. © 2020 Wiley Periodicals, Inc.BACKGROUND Pancreatitis secondary to hypertriglyceridaemia is rare, accounting for less than 5% of pancreatitis presentations. We reviewed our institutional experience with triglyceridaemia induced acute pancreatitis to report the clinical presentation, patient demographics and clinical management. METHODS The Acute Surgical Unit database at a high-volume general surgical referral centre was queried to identify cases of acute pancreatitis secondary to hypertriglyceridaemia between 2016 and 2019. Patient demographics, clinical manifestations, biochemical derangements and treatment regimens were analysed. Current related literature was reviewed. RESULTS There were 496 presentations for acute pancreatitis of which 14 presentations (2.8%), amongst 12 patients were due to hypertriglyceridaemia. The mean triglyceride level at presentation was 92.46 (standard deviation 46.9) mmol/L. Ten patients (83%) had poorly controlled type 2 diabetes. All patients were managed using conservative therapy combined with a restricted fat diet and commenced on long-term anti-lipid therapy to manage associated risk factors. In addition, 10 patients received an insulin infusion and one patient received insulin infusion, plasmapheresis and heparin infusion in combination. The median length of hospital stay was 5.5 (range 3-13) days. Two patients (16%) developed a recurrent episode related to non-compliance to medical therapy. CONCLUSION Hypertriglyceridaemia is a rare cause of acute pancreatitis. Successful management involves the treatment of acute pancreatitis in conjunction with long-term anti-lipid therapy and optimisation of associated risk factors. © 2020 Royal Australasian College of Surgeons.
