Purpose To compare the diagnostic performance of a short dual-pulse sequence magnetic resonance (MR) imaging protocol versus a standard six-pulse sequence multiparametric MR imaging protocol for detection of clinically significant prostate cancer. Materials and Methods This HIPAA-compliant study was approved by the regional ethics committee. Between July 2013 and March 2015, 63 patients from a prospectively accrued study population who underwent MR imaging of the prostate including transverse T1-weighted; transverse, coronal, and sagittal T2-weighted; diffusion-weighted; and dynamic contrast material-enhanced MR imaging with a 3-T imager at a single institution were included in this retrospective study...

OBJECTIVE: The Dietary Inflammatory Index (DII)TM, which was developed to characterize the inflammatory potential of a person's diet, has been shown to be associated with inflammatory conditions such as cancer. The present study aimed to investigate the association between DII scores and colorectal adenoma (CRA), a pre-cancerous condition. DESIGN: Responses to baseline dietary questionnaires were used calculate DII scores. In a cross-sectional study design, the association between DII scores and CRA prevalence was determined in men and women separately using logistic regression models...

BACKGROUND: High doses of corticosteroids are considered the standard treatment for pemphigus. Because long-term corticosteroid treatment can cause severe and even life-threatening side-effects in patients with this disease, we assessed whether first-line use of rituximab as adjuvant therapy could improve the proportion of patients achieving complete remission off-therapy, compared with corticosteroid treatment alone, while decreasing treatment side-effects of corticosteroids. METHODS: We did a prospective, multicentre, parallel-group, open-label, randomised trial in 25 dermatology hospital departments in France (Ritux 3)...

During starvation, intra-mitochondrial sirtuins, NAD(+) sensitive deacylating enzymes that modulate metabolic homeostasis and survival, directly adjust mitochondrial function to nutrient availability; concomitantly, mitochondria elongate to escape autophagic degradation. However, whether sirtuins also impinge on mitochondrial dynamics is still uncharacterized. Here we show that the mitochondrial Sirtuin 5 (Sirt5) is essential for starvation induced mitochondrial elongation. Deletion of Sirt5 in mouse embryonic fibroblasts increased levels of mitochondrial dynamics of 51kDa protein and mitochondrial fission protein 1, leading to mitochondrial accumulation of the pro-fission dynamin related protein 1 and to mitochondrial fragmentation...

Diet and inflammation have been suggested to be important risk factors for oral and pharyngeal cancer. We examined the association between dietary inflammatory index (DII) and oral and pharyngeal cancer in a large case-control study conducted between 1992 and 2009 in Italy. This study included 946 cases with incident, histologically confirmed oral and pharyngeal cancer, and 2492 controls hospitalized for acute non-neoplastic diseases. The DII was computed based on dietary intake assessed by a valid 78-item food frequency questionnaire and was adjusted for non-alcohol energy intake using the residual approach (E-DII)...

Sequences from the DNA barcode region of the mitochondrial COI gene are an effective tool for specimen identification and for the discovery of new species. The Barcode of Life Data Systems (BOLD) (www.boldsystems.org) currently hosts 4.5 million records from animals which have been assigned to more than 490,000 different Barcode Index Numbers (BINs), which serve as a proxy for species. Because a fourth of these BINs derive from Lepidoptera, BOLD has a strong capability to both identify specimens in this order and to support studies of faunal overlap...

Background Hereditary angioedema is a disabling, potentially fatal condition caused by deficiency (type I) or dysfunction (type II) of the C1 inhibitor protein. In a phase 2 trial, the use of CSL830, a nanofiltered C1 inhibitor preparation that is suitable for subcutaneous injection, resulted in functional levels of C1 inhibitor activity that would be expected to provide effective prophylaxis of attacks. Methods We conducted an international, prospective, multicenter, randomized, double-blind, placebo-controlled, dose-ranging, phase 3 trial to evaluate the efficacy and safety of self-administered subcutaneous CSL830 in patients with type I or type II hereditary angioedema who had had four or more attacks in a consecutive 2-month period within 3 months before screening...

Small heat shock proteins (sHsps) prevent aggregation of thermosensitive client proteins in a first line of defense against cellular stress. The mechanisms by which they perform this function have been hard to define due to limited structural information; currently there is only one high-resolution structure of a plant sHsp published, of the cytosolic Hsp16.9. We took interest in Hsp21, a chloroplast-localized sHsp crucial for plant stress resistance, which has even longer N-terminals arms than Hsp16.9, with a functionally important and conserved methionine-rich motif...

Children with cancer and fever are at high risk for sepsis related death. Rapid antibiotic delivery (< 60 minutes) has been shown to reduce mortality. We compared patient outcomes and describe interventions from three separate quality improvement (QI) projects conducted in three United States (US) tertiary care pediatric emergency departments (EDs) with the shared aim to reduce time to antibiotic (TTA) to < 60 minutes in febrile pediatric oncology patients (Temperature > 38.0 C). A secondary objective was to identify interventions amenable to translation to other centers...

INTRODUCTION: Prostate cancer is the most common cancer in men and patients treated with androgen deprivation therapy (ADT) experience unfavourbale changes in body composition and associated metabolic complications, which can increase the risk of cardiovascular disease. We examined the effect of a 6-month program of aerobic and resistance exercise aimed at improving body composition and cardiorespiratory health in this population. METHODS: Ninety-seven men (43-90 years) with localized prostate cancer receiving ADT were randomized to either exercise (EX, n=50) or usual care (CON, n=47)...

When compared to children from the general population, sexually abused children receive more medical services, both for physical and mental health problems. However, possible differences between sexually abused boys and girls remain unknown. The lack of control group in studies that find gender differences also prevents from determining if the differences are specific to sexual abuse or to gender. The objective of the study was to assess differences in physical and mental health between sexually abused boys and girls in comparison to those from the general population...

Mutations in the THAP1 gene encoding the transcription factor THAP1 have been shown to cause DYT6 dystonia. THAP1 contains a highly conserved THAP zinc finger at its N-terminal region which allows specific binding to its target sequences as well as a coiled-coil domain (amino acids 139-190) towards its C-terminus postulated as a protein-protein-binding motif. While several DYT6-causing mutations within the THAP domain were shown to decrease THAP1 activity in transcriptional regulation and DNA-binding, the role of mutations within the coiled-coil domain is rather unknown...

In both colon cancer and type 2 diabetes, metabolic changes induced by upregulation of the Wnt/beta-catenin signaling and downregulation of peroxisome proliferator-activated receptor gamma (PPAR gamma) may help account for the frequent association of these two diseases. In both diseases, PPAR gamma is downregulated while the canonical Wnt/beta-catenin pathway is upregulated. In colon cancer, upregulation of the canonical Wnt system induces activation of pyruvate dehydrogenase kinase and deactivation of the pyruvate dehydrogenase complex...

OBJECTIVE: Create practice guidelines for the appropriate use of red blood cell transfusions in hepatectomy. BACKGROUND: Hepatectomy is associated with a high prevalence of transfusions. A transfusion can be life-saving, but can be associated with important adverse effects. Given the prevalence, the potential for benefit and harm, and the difficulty in conducting clinical trials, transfusion in hepatectomy is well-suited for a study of appropriateness. METHODS: Using the RAND/UCLA appropriateness method, an international, multidisciplinary expert panel in hepatobiliary surgery, anesthesia, transfusion medicine, and critical care rated a series of 468 perioperative scenarios for transfusion appropriateness...

Monotopic proteins exert their function when attached to a membrane surface, and such interactions depend on the specific lipid composition and on the availability of enough area to perform the function. Nanodiscs are used to provide a membrane surface of controlled size and lipid content. In the absence of bound extrinsic proteins, sodium phosphotungstate-stained nanodiscs appear as stacks of coins when viewed from the side by transmission electron microscopy (TEM). This protocol is therefore designed to intentionally promote stacking; consequently, the prevention of stacking can be interpreted as the binding of the membrane-binding protein to the nanodisc...
