ounteracting the behavioral and functional alterations associated with psychiatric disorders, which supports the promising role of the redox system as a novel therapeutic target for the improved treatment of brain disorders. PURPOSE The intraoral stent (IOS) is an individualized mouth opening device that can be used during radiotherapy (RT) for head and neck cancer to prevent unnecessary irradiation to normal tissues. The purpose of the present study was to compare the severity of oral mucositis (OM) between patients using and not using an IOS during RT for maxillary and nasal cavity cancer. PATIENTS AND METHODS We designed and implemented a retrospective cohort study. The study sample included patients with maxillary and nasal cavity cancer who had undergone RT. The primary predictor variable was IOS application, and the outcome variable was the grade of OM. RESULTS The IOS group included 18 patients with an IOS and the control group, 16 patients without an IOS. The parameters of the dose-volume histogram included the median dosage covering 1 mL (D1mL) for the tongue and the mean dosage. The D1mL (36.2 vs 65.4 Gy) and mean dosage (4.9 Gy vs 25.9 Gy) were both significantly lower in the IOS group than in the control group (P less then .005). The incidence of OM using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0, were significantly different between the oral stomatitis grade and the use of an IOS (P = .028). A significant difference was found in opioid use between the IOS and control groups (P = .009). CONCLUSIONS The use of an IOS decreased the radiation dosage to the tongue, the grade of OM, and opioid usage during RT. OBJECTIVE Competing events are often ignored in epidemiological studies. Conventional methods for the analysis of survival data assume independent or non-informative censoring, which is violated when subjects that experience a competing event are censored. Because many survival studies do not apply competing risk analysis, we explain and illustrate in a non-mathematical way how to analyse and interpret survival data in the presence of competing events. STUDY DESIGN AND SETTING Using data from the Longitudinal Aging Study Amsterdam, both marginal analyses (Kaplan-Meier method and Cox proportional hazards regression) and competing risk analyses (cumulative incidence function (CIF), cause-specific and subdistribution hazard regression) were performed. We analysed the association between sex and depressive symptoms, in which death prior to the onset of depression was a competing event. RESULTS The Kaplan-Meier method overestimated the cumulative incidence of depressive symptoms. Instead, the CIF should be used. As the subdistribution hazard model has a one-to-one relation with the CIF it is recommended for prediction research, whereas the cause-specific hazard model is recommended for etiologic research. CONCLUSION When competing risks are present, the type of research question guides the choice of the analytical model to be used. In any case, results should be presented for all event types. INTRODUCTION In cases of sacral nerve avulsion injuries, proximal nerve stumps are not available because of its protected position in pelvis, and results of nerve repair or graft are unsatisfactory. Nerve transfer can reduce the regeneration time and improve the results of recovery. HYPOTHESIS The obturator nerve transfer to the tibial nerve via saphenous nerve graft is possible and feasible. MATERIALS AND METHODS Ten male adult cadaveric lower limbs dissected to identify the location of the anterior branch of obturator nerve, the saphenous nerve and the medial gastrocnemius branch. The saphenous nerve was cut from its origin and transferred to the anterior branch of obturator nerve. As well, it was cut distally and transferred to the medial gastrocnemius branch. After nerve coaptation, surface area and fascicle count were determined by histological methods. RESULTS In all limbs, the proximal and distal stumps of saphenous nerve were reached the anterior branch of obturator and the medial gastrocnemius branch, respectively without tension. The mean of fascicle number in the anterior branch of obturator nerve, proximal and distal stump of the saphenous nerve and stump of medial gastrocnemius nerve branch were 2.90±0.99, 4.50±2.70, 4.00±2.26 and 4.30±1.25, respectively. DISCUSSION This study showed that it is possible to transfer the obturator nerve to the medial gastrocnemius branch via saphenous nerve bridge; and their histological parameters are match in a good manner. Therefore, this technique is suggested for patients with sacral nerve avulsion injuries. LEVEL OF EVIDENCE IV, case series of cadaveric study. BACKGROUND Small fracture fragments of the palmar lunate facet of the distal radius can be difficult to stabilize and may cause loss of reduction and even subluxation of the radiocarpal joint. Itacnosertib chemical structure MATERIAL & METHODS The aims of the study were to investigate fracture patterns of the intermediate column in 101 intra-articular distal radius fractures with three-dimensional computed tomography, and to determine the prevalence of palmar lunate facet fracture fragments. The size of the fragments was measured to find out how many fragments were small. RESULTS The palmar lunate facet fragment was present in 61 fractures. Mean length of the palmar cortex measured 13.5mm (range 3 to 26.9) and mean area of the lunate facet 115 mm2 (range 31 to 267). Seventeen percent of intra-articular distal radius fractures had a palmar lunate facet fragment with a short palmar cortex. CONCLUSION With accurate analysis of the preoperative computed tomography scans the typical fracture patterns of the palmar lunate facet are recognisable and adequate fixation technique can be chosen to avoid loss of reduction. LEVEL OF EVIDENCE IV. Treatment with valproate is associated with hepatic steatosis, but the mechanisms are not fully elucidated in human cell systems. We therefore investigated the effects of valproate on fatty acid and triglyceride metabolism in HepaRG cells, a human hepatoma cell line. In previously fatty acid loaded HepaRG cells, valproate impaired lipid droplet disposal starting at 1 mM after incubation for 3 or 7 days. Valproate increased the expression of genes associated with fatty acid import and triglyceride synthesis, but did not relevantly affect expression of genes engaged in fatty acid activation. Valproate impaired mitochondrial fatty acid metabolism by inhibiting β-ketothiolase and the function of the electron transport chain, which was associated with increased mitochondrial reactive oxygen species production. Valproate increased the mitochondrial DNA copy number per HepaRG cell, possibly as a consequence of impaired mitochondrial function. Valproate decreased the hepatocellular mRNA and protein expression of the fatty acid binding protein 1 (FABP1) and of the microsomal triglyceride transfer protein (MTTP) at 1 mM and increased the hepatocellular concentration of free fatty acids.
