AflaB2® and osteoarthritis: a multicentric, observational, post-marketing surveillance study in Indian patients suffering from knee osteoarthritis

Background: Osteoarthritis (OA) is one of the most debilitating chronic degenerative joint disorder characterized by pain, inflammation and stiffness of joints with wear and tear of the cartilage. Recent evidences suggest the involvement of the immune pathway in OA development. This study was conducted to evaluate the efficacy and safety of AflaB2® capsules containing Aflapin® and native collagen type II in knee OA patients.Methods: Total 40 knee OA subjects were enrolled at the out-patient department (OPD) of three different sites under supervision of physicians as per the inclusion and exclusion criteria of the study. Subjects were instructed to consume AflaB2® capsules once daily orally for three months. They were informed to visit the respective study center as per the schedule visits to assess and record the efficacy and safety.Results: AflaB2® treatment showed significant reduction in pain and stiffness with improvement in physical functions compared to the baseline. The reduction in pain score was observed from 2nd visit on visual analogue scale (VAS). The VAS score was reduced to 1.63±1.23 (p<0.001) from its baseline score 6.0±1.04 at the end of the treatment. The WOMAC Total Score was reduced to 18.1±6.04 (p<0.001) from its baseline score 74.4±8.07 at the end of the treatment. The improvement was observed in WOMAC pain, stiffness and physical functions score. No significant side-effect was reported with AflaB2® treatment throughout the study.Conclusions: The present study provides the evidence in support of the potential efficacy and excellent tolerability of oral intake of AflaB2® capsules in reducing OA symptoms

Determining crystal structures through crowdsourcing and coursework

We show here that computer game players can build high-quality crystal structures. Introduction of a new feature into the computer game Foldit allows players to build and real-space refine structures into electron density maps. To assess the usefulness of this feature, we held a crystallographic model-building competition between trained crystallographers, undergraduate students, Foldit players and automatic model-building algorithms. After removal of disordered residues, a team of Foldit players achieved the most accurate structure. Analysing the target protein of the competition, YPL067C, uncovered a new family of histidine triad proteins apparently involved in the prevention of amyloid toxicity. From this study, we conclude that crystallographers can utilize crowdsourcing to interpret electron density information and to produce structure solutions of the highest quality

Functional outcome of diaphyseal fractures of femur managed by closed intramedullary interlocking nailing in adults

Objective: To study the effectiveness, advantages, disadvantages and failure rates of closed intramedullary interlocking nailing of daiphyseal fractures of the femur in adults. Materials and Methods: A total of 30 cases of diaphyseal femur fractures in adults, who have been treated with closed intramedullary interlocking nailing were studied from 2008 - 2010. Data was analyzed both with regards to the clinical and radiological outcome to evaluate the effectiveness, functional outcome and morbidity associated with the procedure. Results: Average age of the patient was 27.4 years with male preponderance. Road traffic accidnents were the most common mode of injury; middle third shaft fractures were most commonly seen (56.66%); comminuted and transverse fractures (63.33%) were the commonest fracture pattern. The union rate was 96.6%. Five patients had superfi cial infection, four had shortening of limb, and in two cases union was delayed. Excellent to good results were seen in 86.6% cases as per modifi ed Klaus and Klemm criteria. Consclusion: Closed intramedullary interlocking nailing has now become the treatment of choice for closed diaphyseal fractures of femur in adults, especially those with high comminution, long spiral, and segmental fractures. Interlocking nail offers the added advantages of early joint mobilization, early weight bearing, early muscle rehabilitation, shortened hospital stay, and most importantly early return to work and prefracture state
