The benefits of data sharing are well-established and an increasing number of policies require that data be shared upon publication of the main study findings. As data sharing becomes the new norm, there is a heightened need for additional resources to drive efficient data reuse. This article describes the development and implementation of the Data and Specimen Hub (DASH) by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) to promote data sharing from NICHD-funded studies and enable researchers to comply with NIH data sharing policies...

BACKGROUND: Solid organ transplant recipients (SOTR) with pretransplant malignancies (PTM) have worse overall survival (OS) compared to recipients without history of malignancy. However, it is unknown whether the increased risk of mortality is due to recurrent cancer-related deaths. METHODS: All SOTR in Ontario between 1991 and 2010 were identified and matched 1:2 to recipients without PTM using a propensity score. OS was compared using the Kaplan-Meier estimator and Cox proportional hazard models...

OBJECTIVE: In this multicenter study, we sought to evaluate comparative safety and efficacy of combined IV thrombolysis (IVT) and mechanical thrombectomy (MT) vs direct MT in emergent large vessel occlusion (ELVO) patients. METHODS: Consecutive ELVO patients treated with MT at 6 high-volume endovascular centers were evaluated. Standard safety and efficacy outcomes (successful reperfusion [modified Thrombolysis in Cerebral Infarction IIb/III], functional independence [FI] [modified Rankin Scale (mRS) score of 0-2 at 3 months], favorable functional outcome [mRS of 0-1 at 3 months], functional improvement [mRS shift by 1-point decrease in mRS score]) were compared between patients who underwent combined IVT and MT vs MT alone...

We were encouraged to investigate the reasons for large amounts of foam observed in bloodlines during hemodialysis (HD). Foam was visible in the venous air trap within the Artis Gambro dialysis device. Estimates of the extent of foam were graded (0-no foam, 10-extensive foam) by two persons that were blind to the type of dialyzer used. Thirty-seven patients were involved in the dialysis procedures. Consecutive dialyses were graded using dialyzers from Fresenius Medical Care (CorDiax dialyzers that were used for high flux HD-FX80 and FX100, and for hemodiafiltration-FX1000)...

Background: Vulvodynia is an idiopathic vulvovaginal pain condition that has significant sexual and relational consequences. Most women with vulvodynia continue to have intercourse, possibly because of a desire to approach positive outcomes (e.g., intimacy) and avoid negative outcomes (e.g., partner disappointment). Purpose: This study examined daily associations between approach and avoidance sexual goals and women's pain during intercourse and couples' sexual and relational well-being, as well as the mediating role of sexual cues...

Comparison of the genome of the Gram negative human pathogen Haemophilus quentini MP1 with other Haemophilus species revealed that, although it is more closely related to Haemophilus haemolyticus than Haemophilus influenzae, the pathogen is in fact genetically distinct, a finding confirmed by phylogenetic analysis using the H. influenzae multilocus sequence typing genes. Further comparison with two other H. quentini strains recently identified in Canada revealed that these three genomes are more closely related than any other Haemophilus species, however there is still some sequence variation...

Genome-wide association studies (GWAS) have identified approximately 100 breast cancer risk loci. Translating these findings into a greater understanding of the mechanisms that influence disease risk requires identification of the genes or non-coding RNAs that mediate these associations. Here, we use Capture Hi-C (CHi-C) to annotate 63 loci; we identify 110 putative target genes at 33 loci. To assess the support for these target genes in other data sources we test for associations between levels of expression and SNP genotype (eQTLs), disease-specific survival (DSS), and compare them with somatically mutated cancer genes...

The aim of this study is to link polytetrafluoroethylene (PTFE) surface characteristics with its wetting properties in the nanoscale. To do this using Molecular Dynamics (MD) simulation three series of rough PTFE surfaces were generated by the annealing and compressing, and next characterized by the application of the MD version of the Atomic Force Microscopy (AFM) method. The values of specific surface areas were additionally calculated. The TIP4P/2005 water model was used to the study of wetting properties of obtained PTFE samples...

BACKGROUND: Breast cancer patients experience various side effects during cancer therapy, often resulting in reduced quality of life and poor adherence to treatment. A limited range of proven interventions has been developed to target such side effects. While Tai Chi offers benefits for the health and well-being of breast cancer survivors, the effectiveness of Tai Chi across the treatment continuum has not been evaluated. Improved patient education and support has been suggested as a priority for breast cancer care...

A proportion of cutaneous melanomas display neval remnants on histologic examination. Converging lines of epidemiologic and molecular evidence suggest that melanomas arising from nevus precursors differ from melanomas arising de novo. In a large, population-based study comprising 636 cutaneous melanomas subjected to dermatopathology review, we explored the molecular, host and environmental factors associated with the presence of neval remnants. We found nevus-associated melanomas were significantly associated with younger age at presentation, non-brown eye color, trunk site, thickness <0...

Preterm birth (PTB) can lead to lifelong complications and challenges. Identifying and monitoring molecular signals in easily accessible biological samples that can diagnose or predict the risk of preterm labour (PTL) in pregnant women will reduce or prevent PTBs. A number of studies identified putative biomarkers for PTL including protein, miRNA and hormones from various body fluids. However, biomarkers identified from these studies usually lack consistency and reproducibility. Extracellular vesicles (EVs) in circulation have gained significant interest in recent years as these vesicles may be involved in cell-cell communication...

Unicompartmental knee arthroplasty (UKA) is a bone conserving and ligament-sparing procedure that reliably restores normal knee kinematics and function for arthritis limited either to the medial or the lateral compartment of the knee. Although there is enough evidence to demonstrate that the UKA offers good medium to long-term success given the correct patient selection, prosthesis design, and implantation technique, there are several reports to suggest inferior survival rates in comparison with the total knee arthroplasty (TKA)...

Biological and engineering applications of superhydrophobic surfaces are limited by the stability of the wetting state determined by the transition from the Cassie-Baxter (CB) state to the Wenzel state (C-W transition). In this paper, we performed water droplet squeeze tests to investigate the critical conditions for the C-W transition for solid surfaces with periodic micropillar arrays. The experimental results indicate that the critical transition pressure for the samples with varying micropillar dimensions are all significantly higher than the theoretical predictions...

BACKGROUND: Our goal is to determine short- and long-term outcomes of simple gastroschisis (SG) and complicated gastroschisis (CG) patients including quality of life (QoL) measures, surgical reoperation rates, and residual gastrointestinal symptom burden. MATERIALS AND METHODS: Retrospective chart review of patients who underwent surgical repair of gastroschisis between January 1, 2009, and December 31, 2012, was performed at a quaternary children's hospital. Parent telephone surveys were conducted to collect information on subsequent operations and current health status as well as to assess QoL using two validated tools...

Although mutations in more than 90 genes are known to cause CMT, the underlying genetic cause of CMT remains unknown in more than 50% of affected individuals. The discovery of additional genes that harbor CMT2-causing mutations increasingly depends on sharing sequence data on a global level. In this way-by combining data from seven countries on four continents-we were able to define mutations in ATP1A1, which encodes the alpha1 subunit of the Na+ ,K+ -ATPase, as a cause of autosomal-dominant CMT2. Seven missense changes were identified that segregated within individual pedigrees: c...

BACKGROUND: The amount of bone accrued during adolescence is an important determinant of later osteoporosis risk. Little is known about the influence of dietary patterns (DPs) on the bone during adolescence and their potential long-term implications into adulthood. We examined the role of adolescent DPs on adolescent and young adult bone and change in DPs from adolescence to young adulthood. METHODS: We recruited participants from the Saskatchewan Pediatric Bone Mineral Accrual Study (1991-2011)...
