Many new circulating recombinant forms (CRFs) and unique recombinant forms (URFs) of HIV-1 have been found in men who have sex with men (MSM) in recent years, in China. In this study, a unique HIV-1 recombinant genome (SN153) was characterized from an HIV-positive male infected through homosexual behavior in Shaanxi, China. The mosaic pattern had a complex intersubtype recombinant structure with six breakpoints, with three subtype C segments inserted into subtype B backbone. And three similar breakpoints with CRF07_BC were observed in the pol gene...

Adolescent and young adult (AYA) patients with hematological malignancy aged 15 to 39 years are recognized as a separate entity, and the efficacy and safety of unrelated cord blood transplantation (CBT) for chronic myeloid leukemia (CML) in AYA patients has not been reported. From March 2002 to June 2015, total of 106 CML patients received allogeneic hematopoietic cell transplantation (allo-HCT) in our center. Included in the present study were CML patients aged 15 to 39 years who received unrelated CBT or sibling allo-HCT, and 74 consecutive AYA patients with CML enrolled in this analysis...

BACKGROUND & METHODS: The ICONIC project has developed an automated high-throughput pipeline to generate HIV nearly full-length genomes (NFLG, i.e. from gag to nef) from next-generation sequencing (NGS) data. The pipeline was applied to 420 HIV samples collected at University College London Hospitals NHS Trust and Barts Health NHS Trust (London) and sequenced using an Illumina MiSeq at the Wellcome Trust Sanger Institute (Cambridge). Consensus genomes were generated and subtyped using COMET, and unique recombinants were studied with jpHMM and SimPlot...

Studies have shown that Raman spectroscopic analysis of fingernail clippings can help differentiate between post-menopausal women who have and who have not suffered a fracture. However, all studies to date have been retrospective in nature, comparing the proteins in nails sourced from women, post-fracture. The objective of this study was to investigate the potential of a prospective test for hip fracture based on spectroscopic analysis of nail tissue. Archived toenail samples from post-menopausal women aged 50 to 63 years in the Nurses' Health Study were obtained and analysed by Raman spectroscopy...

Graft versus host disease (GVHD) is a common complication after hematopoietic cell transplantation (HCT) and associated with significant morbidity and mortality. Preventing GVHD without chronic therapy or increasing relapse is a desired goal. Here, we report a benchmark analysis to evaluate the performance of six GVHD prevention strategies tested at single institutions compared to a large multicenter outcomes database as a control. Each intervention was compared to the control for the incidence of acute and chronic GVHD and overall survival and against novel composite endpoints: acute and chronic GVHD, relapse-free survival (GRFS) and chronic GVHD, relapse-free survival (CRFS)...

PURPOSE: To compare transplant outcomes in patients with advanced myelodysplastic syndrome (MDS) after CD34+ selected or unmodified allografts. PATIENTS AND METHODS: This analysis included initially 181 patients; 60 underwent CD34+ selected transplant and 121 had an unmodified transplant. Due to significant differences in disease characteristics, the analysis was limited to patients who had <10% blasts prior to transplant (N=145). Two groups were defined: (1) low risk: good and intermediate risk cytogenetics (CD34+, N=39; unmodified, N=46), and (2) high risk: poor and very poor risk cytogenetic (CD34+, N=19; unmodified, N=41)...

Reduced-intensity conditioning (RIC) and t-cell depletion (TCD) through CD34+ selection without the use of post-transplant immunosuppression are 2 strategies used to reduce non-relapse mortality (NRM) in older patients after allogeneic hematopoietic cell transplantation (allo-HCT). To compare the efficacy of both approaches (RIC and TCD), we evaluated the outcomes of AML and MDS patients > 50 years who underwent allo-HCT from an HLA-matched donor with one of these strategies. Baseline characteristics were comparable between patients receiving TCD (n=204) and RIC (n=151) except for more unrelated donors (68% vs...

Nutrients released into soils from uncoated fertilizer granules are lost continuously due to volatilization, leaching, denitrification, and surface run off. These issues have caused economic loss due to low nutrient absorption efficiency and environmental pollution due to hazardous emissions and water eutrophication. Controlled-release fertilizers (CRFs) can change the release kinetics of the fertilizer nutrients through an abatement strategy to offset these issues by providing the fertilizer content in synchrony with the metabolic needs of the plants...

Currently, complex HIV-1 recombination among the B', C, and CRF01_AE genotypes have frequently arisen in Yunnan, China. A novel HIV-1 complex circulating recombinant form (CRF) consisting of B', C, and CRF01_AE (CRF96_cpx) was recently characterized from three epidemiologically unlinked individuals. Two strains of them were isolated from the injecting drug users in this study, the remaining one strain (JL. RL01) obtained from a previous report in Jilin province. Phylogenetic analysis based on near full-length genome (NFLG) revealed that CRF96_cpx formed a distinct monophyletic cluster supported by a high bootstrap value of 100%, distantly related to all known HIV-1 subtypes/CRFs...

Currently, data on HIV-1 circulating strains among men who have sex with men (MSM) in Argentina is scarce. In South America, the distribution and the prevalence of BF recombinants are dissimilar and exhibit an underappreciated heterogeneity of recombinant structures. Here, we studied for the first time the genetic diversity of HIV-1 BF recombinants and their evolution over time through in-depth phylogenetic analysis and multiple recombination detection methods involving 337 HIV-1 nucleotide sequences (25 near full-length (NFL) and 312 partial pol gene) obtained from Argentinean MSM...

Clinical risk factors for fracture in Southern Brazil are similar to those used in Fracture Risk Assessment Tool (FRAX®). Age-dependent intervention thresholds had higher accuracy than a fixed cut-off point. INTRODUCTION: Access to bone mineral density testing is wanted for a large part of the Brazilian population. The FRAX® has an option to calculate the risk of fracture without this costly evaluation but relies on the clinical risk factors (CRFs) identified in the source cohorts used to generate FRAX...

This study explored the conservation values of communally reserved forests (CRFs), which local indigenous communities deliberately preserve within their area of shifting cultivation. In the current landscape of rural Borneo, CRFs are the only option for conservation because other forested areas have already been logged or transformed into plantations. By analyzing their alpha and beta diversity, we investigated how these forests can contribute to restore regional biodiversity. Although CRFs were fragmented and some had been disturbed in the past, their tree species diversity was high and equivalent to that of primary forests...

BACKGROUND: Gastric fundoplication is the most common noncardiac operation in children with congenital cardiac disease. While prior studies validated safety of laparoscopy in this population, we hypothesize that children with cardiac risk factors (CRFs) are likelier to undergo open fundoplication (OF) but experience greater morbidity than after laparoscopic fundoplication (LF). MATERIALS AND METHODS: Utilizing 2013 National Surgical Quality Improvement Program-Pediatrics Public-Use-File, pediatric patients undergoing LF and OF were stratified to none, minor, major, or severe CRFs...

Features from outside the classical receptive field (CRF) can modulate the stimulus-driven activity of single cells in the primary visual cortex. This modulation, mediated by horizontal and feedback networks, has been extensively described as a variation of firing rate and is considered the basis of processing features as, for example, motion contrast. However, surround influences have also been identified in pairwise spiking or local field coherence. Yet, evidence about co-existence and integration of different neural signatures remains elusive...

OBJECTIVE: We aimed to examine the effects of a dose escalation for prostate cancer patients receiving long-term androgen deprivation therapy (ADT). METHODS: A retrospective analysis of 605 patients treated with radiotherapy (RT) and long-term ADT (National Comprehensive Cancer Network criteria-defined intermediate-risk, minimum 10 months; high-risk and very-high-risk, minimum 20 months) was performed. The median ADT time was 31 months. Cox's proportional hazards models were used to compare biochemical disease-free survival (bDFS), clinical relapse-free survival (cRFS) and overall survival (OS) between the ≥70, <78 Gy group and 78 Gy group in a univariate analysis and to assess the effects of the dose escalation on bDFS in a multivariate analysis...

OBJECTIVES: The estimation of fracture risk using clinical risk factors (CRFs) is of primary concern in osteoporosis management, but only some risk factors have been thoroughly evaluated and incorporated in predictive models. We have launched a large prospective study, the 'Fracture Risk Brussels Epidemiological Enquiry' (FRISBEE), to develop a new predictive model for osteoporotic fractures. The aims of this report are to describe the methodology of the FRISBEE study and to compare the distribution of CRFs in our cohort with those reported in other large studies...

The major objective of preclinical translational epilepsy research is to advance laboratory findings toward clinical application by testing potential treatments in animal models of seizures and epilepsy. Recently there has been a focus on the failure of preclinical discoveries to translate reliably, or even to be reproduced in different laboratories. One potential cause is a lack of standardization in preclinical data collection. The resulting difficulties in comparing data across studies have led to high cost and missed opportunity, which in turn impede clinical trials and advances in medical care...

Accurate and reliable brain tumor segmentation is a critical component in cancer diagnosis, treatment planning, and treatment outcome evaluation. Build upon successful deep learning techniques, a novel brain tumor segmentation method is developed by integrating fully convolutional neural networks (FCNNs) and Conditional Random Fields (CRFs) in a unified framework to obtain segmentation results with appearance and spatial consistency. We train a deep learning based segmentation model using 2D image patches and image slices in following steps: 1) training FCNNs using image patches; 2) training CRFs as Recurrent Neural Networks (CRF-RNN) using image slices with parameters of FCNNs fixed; and 3) fine-tuning the FCNNs and the CRF-RNN using image slices...
