This study compares clinical, radiographic and patient-reported outcomes among telescoping and traditional screws for the treatment of slipped capital femoral epiphysis (SCFE). We hypothesized that telescoping screws would prevent slip progression and result in preserved femoral neck growth and improved patient-reported outcomes. Traditional screws were compared to telescoping screws in a 21 matched cohort based on age at initial surgery, length of radiographic follow-up and whether or not the hip was pinned prophylactically or as a treatment for SCFE. Neck length and telescoping screw length were measured. The patient-reported outcomes were obtained at routine clinic visits. Total 42 hips were included with a mean follow-up of 24.5 ± 3.3 months. No patients developed avascular necrosis, chondrolysis or needed revision surgical procedures. Telescoping screws increased in length for the entire cohort by a mean of 6.0 ± 4.3 mm. Neck length change was not different in SCFE hips when treated with traditional screws vs. telescoping screws (P = 0.527). However, there was a difference in neck length change between the two groups when comparing prophylactically treated hips (P = 0.001). There were no significant differences in patient-reported outcomes among hips treated with telescoping screws compared to traditional screws. Traditional and telescoping screws are both effective for the treatment of SCFE. Telescoping screws have an advantage when prophylactically treating hips that are at risk of slipping as they don't lead to the coxa breva that is seen with traditional screws. However, both treatment methods had similar patient-reported outcomes. Depression is moderately heritable but there is no common genetic variant which has a major effect on susceptibility. A previous analysis of 50 000 exome-sequenced subjects failed to implicate any genes or sets of genes in which rare variants were associated with risk of affective disorder requiring specialist treatment. A much larger exome-sequenced dataset is now available. Data from 200 632 exome-sequenced UK Biobank participants was analysed. Subjects were treated as cases if they had reported having seen a psychiatrist for 'nerves, anxiety, tension or depression'. Gene-wise weighted burden analysis was performed to see if there were any genes or sets of genes for which there was an excess of rare, functional variants in cases. There were 22 886 cases and 176 486 controls. There were 22 642 informative genes but no gene or gene set produced a statistically significant result after correction for multiple testing. None of the genes or gene sets with the lowest P values appeared to be an obvious biological candidate. The results conform exactly with the expectation under the null hypothesis. It seems unlikely that the use of common, poorly defined phenotypes will produce useful advances in understanding genetic contributions to affective disorder and it might be preferable to focus instead on obtaining large exome-sequenced samples of conditions such as bipolar 1 disorder and severe, recurrent depression.

Epigenetic mechanisms are involved in both vulnerability to suicidal behavior and stress. This is a pilot study of 60 patients with schizophrenia spectrum disorders (36 men and 24 women), with an average age of 43.75 ± 12.24 years. We analyzed the effects of (1) perceived stress and (2) the mediation of genome-wide methylation (~450 000 CpG sites) on suicidal ideation severity. The top CpG site mediating the effect of stress on suicidal ideation was the cg10782349 located in the ZNF701 gene on chromosome 19, facilitating the effect through DNA hypermethylation. Selleck Curzerene These preliminary results indicate that DNA methylation in peripheral tissues can clarify the complex relationship between stress and suicidal ideation in schizophrenia.Valproic acid (VPA) is a powerful antiepileptic drug that was associated with several neurological and hepatic problems especially with increasing its dose and duration. These problems may be metabolic in origin and related to glucose homeostasis. So, the present study investigated the effect of different doses and durations of VPA on the expression of glucose transporters (Glut1 and Glut4), oxidative stress and inflammatory cytokine (IL-6) in the liver and specific brain regions. Seventy-two male Sprague-Dawley rats were randomly allocated into three equal groups (1) saline group, (2) 200 mg VPA group and (3) 400 mg VPA group. By the end of experiments, the expressions of Glut1, Glut4 nuclear factor erythroid-like 2 related factor (Nrf2), IL-6 and oxidative stress markers [malondialdehyde (MDA) and glutathione (GSH)] in the liver, corpus striatum, prefrontal cortex (PFC) and cerebellum were assessed. We found that administration of VPA (200 mg and 400 mg) caused a significant decrease in the Glut1 and Glut4 expression in different tissues in a dose- and time-dependent manner (P less then 0.01). Also, VPA (200 and 400 mg) caused a significant increase in MDA with a decrease in GSH in tissues at different times. Moreover, VPA (200 and 400 mg) caused significant upregulation in IL-6 expression and downregulation in Nrf2 expression (P less then 0.01). The results suggest that increasing the dose and time of VPA therapy downregulates Glut1 and Glut4 in the liver and brain which may impair glucose uptake in these tissues. This effect was associated with enhanced oxidative stress, downregulation of nrf2 and upregulation of IL-6 in liver and brain tissues.
