STUDY DESIGN Cross-sectional study. OBJECTIVE To determine the prevalence and potential risk factors of vitamin D deficiency and insufficiency among Malaysian children with spina bifida. SETTING Four Malaysian tertiary hospitals. METHODS Children with spina bifida were assessed for potential demographic, disease severity and lifestyle risk factors for vitamin D deficiency and insufficiency. Blood for 25-hydroxy vitamin D (25(OH)D) was taken. Vitamin D deficiency was defined as 25(OH)D levels ≤ 37.5 nmol/L and insufficiency as 37.6-50 nmol/L. RESULTS Eighty children aged 2-18 years (42 males) participated in the study. Vitamin D levels ranged from 14 to 105 nmol/L (mean 52.8, SD 19.1). Vitamin D deficiency was identified in 18 (22.5%) and insufficiency in 26 (32.5%) children. Logistic regression analysis showed that skin exposure to sunlight ≤ 21% body surface area (OR 6.2, CI 1.7-22.9) and duration of sun exposure ≤ 35 min/day (OR 4.0, CI 1.2-14.1) were significant risk factors for vitamin D deficiency and insufficiency, respectively. CONCLUSIONS Over half (55%) of Malaysian children with spina bifida seen in urban tertiary hospitals have vitamin D insufficiency and deficiency. Lifestyle sun exposure behaviours were risk factors for vitamin D deficiency and insufficiency.STUDY DESIGN A retrospective chart review. OBJECTIVES Total en bloc spondylectomy (TES) has been reported to decrease the rate of local recurrence and increase survival. Although it is important to achieve early recovery of physical functions after surgery, no studies have evaluated rehabilitation outcomes during the acute phase after TES. This study evaluated ambulatory functions and activities of daily living (ADLs) after surgery and analyzed the prognostic significance of variables affecting rehabilitation outcomes at 1 month after TES. SETTING University hospital in Kanazawa, Japan. METHODS This study included 140 patients with spinal tumors who underwent TES between April 2010 and April 2017. Demographic characteristics, neurological functions, perioperative complications functional status as measured by the Functional Independent Measure, and independent indoor walking based on the Spinal Cord Independent Measure were extracted from medical records. Tamoxifen Multivariate analyses were performed to assess factors associated with the recovery of ambulation and ADL at 1 month after TES. RESULTS Preoperative neurological deficits were observed in 51 patients (36%), and postoperative neurological deterioration was found in 41 patients (29%). Multivariate analyses indicated that preoperative neurological deficits (odds ratio [OR], 5.23; 95% confidence interval [CI], 2.07-15.99), postoperative cerebrospinal fluid leakage (OR, 13.42; 95% CI, 2.93-78.82), surgical site infections (OR, 15.27; 95% CI, 2.26-127.7), and postoperative neurological deterioration (OR, 4.86; 95% CI, 1.33-19.99) were risk factors for walking ability and recovery of ADL (P  less then  0.01). CONCLUSIONS This study identified preoperative neurological dysfunction and perioperative complications as independent risk factors for poor recovery of ambulation and ADL early after TES.Genetic cardiomyopathy is a group of intractable cardiovascular disorders involving heterogeneous genetic contribution. This heterogeneity has hindered the development of life-saving therapies for this serious disease. Genetic mutations in dystrophin and its associated glycoproteins cause cardiomuscular dysfunction. Large animal models incorporating these genetic defects are crucial for developing effective medical treatments, such as tissue regeneration and gene therapy. In the present study, we knocked out the δ-sarcoglycan (δ-SG) gene (SGCD) in domestic pig by using a combination of efficient de novo gene editing and somatic cell nuclear transfer. Loss of δ-SG expression in the SGCD knockout pigs caused a concomitant reduction in the levels of α-, β-, and γ-SG in the cardiac and skeletal sarcolemma, resulting in systolic dysfunction, myocardial tissue degeneration, and sudden death. These animals exhibited symptoms resembling human genetic cardiomyopathy and are thus promising for use in preclinical studies of next-generation therapies.Wolfram Syndrome 1 (WFS1) protein is an endoplasmic reticulum (ER) factor whose deficiency results in juvenile-onset diabetes secondary to cellular dysfunction and apoptosis. The mechanisms guiding β-cell outcomes secondary to WFS1 function, however, remain unclear. Here, we show that WFS1 preserves normal β-cell physiology by promoting insulin biosynthesis and negatively regulating ER stress. Depletion of Wfs1 in vivo and in vitro causes functional defects in glucose-stimulated insulin secretion and insulin content, triggering Chop-mediated apoptotic pathways. Genetic proof of concept studies coupled with RNA-seq reveal that increasing WFS1 confers a functional and a survival advantage to β-cells under ER stress by increasing insulin gene expression and downregulating the Chop-Trib3 axis, thereby activating Akt pathways. Remarkably, WFS1 and INS levels are reduced in type-2 diabetic (T2DM) islets, suggesting that WFS1 may contribute to T2DM β-cell pathology. Taken together, this work reveals essential pathways regulated by WFS1 to control β-cell survival and function primarily through preservation of ER homeostasis.While the past decade has seen meaningful improvements in clinical outcomes for multiple myeloma patients, a subset of patients does not benefit from current therapeutics for unclear reasons. Many gene expression-based models of risk have been developed, but each model uses a different combination of genes and often involves assaying many genes making them difficult to implement. We organized the Multiple Myeloma DREAM Challenge, a crowdsourced effort to develop models of rapid progression in newly diagnosed myeloma patients and to benchmark these against previously published models. This effort lead to more robust predictors and found that incorporating specific demographic and clinical features improved gene expression-based models of high risk. Furthermore, post-challenge analysis identified a novel expression-based risk marker, PHF19, which has recently been found to have an important biological role in multiple myeloma. Lastly, we show that a simple four feature predictor composed of age, ISS, and expression of PHF19 and MMSET performs similarly to more complex models with many more gene expression features included.
