INTRODUCTION: There is significant morbidity associated with fragile X syndrome. Unfortunately, most maternal carriers are clinically silent during their reproductive years. Because of this, many experts have put forward the notion of preconception or prenatal fragile X carrier screening for females. This study aimed to determine the prevalence of fragile X syndrome pre-mutation and asymptomatic full-mutation carriers in a Chinese pregnant population, and the distribution of cytosine-guanine-guanine (CGG) repeat numbers using a robust fragile X mental retardation 1 (FMR1) polymerase chain reaction assay...

INTRODUCTION: Capacity building approaches are useful in large-scale community-based health promotion interventions. However, models to guide and evaluate capacity building among social service agency staff in community settings are rare in the literature. This paper describes the development and evaluation of a 1-day (7 h) train-the-trainer (TTT) workshop for the "Enhancing Family Well-Being Project". The workshop aimed at equipping staff from different community agencies with the knowledge and skills to design, implement, and evaluate positive psychology-based interventions for their clients in Sham Shui Po, an over-crowded and low-income district in Hong Kong...

BACKGROUND: Routine clinical application of circulating tumour cells (CTCs) for blood based diagnostics is yet to be established. Despite growing evidence of their clinical utility for diagnosis, prognosis and treatment monitoring, the efficacy of a robust platform and universally accepted diagnostic criteria remain uncertain. We evaluate the diagnostic performance of a microfluidic CTC isolation platform using cytomorphologic criteria in patients undergoing lung cancer surgery. METHODS: Blood was processed from 51 patients undergoing surgery for known or suspected lung cancer using the ClearBridge ClearCell FX system(TM) (ClearBridge Biomedics, Singapore)...

PURPOSE: Waiting times remain one of the most vexing patient satisfaction challenges facing healthcare. Waiting time uncertainty can cause patients, who are already sick or in pain, to worry about when they will receive the care they need. These waiting periods are often difficult for staff to predict and only rough estimates are typically provided based on personal experience. This level of uncertainty leaves most patients unable to plan their calendar, making the waiting experience uncomfortable, even painful...

OBJECTIVE: The aim of the study was to evaluate outcomes after resection of colorectal liver metastases (CRLM) and concurrent extrahepatic disease (EHD), and to define prognostic factors. BACKGROUND: There is increasing evidence to support resection of liver metastases and concurrent EHD in selected patients. Long-term survival data are lacking, and prognostic factors are not well defined. METHODS: Retrospective review of 219 patients was undertaken between January 1992 and December 2012, who underwent hepatectomy for CRLM and resection of synchronous EHD...

Fibroblast growth factor receptor 1 (FGFR1) amplification drives poor prognosis and is an emerging therapeutic target. We sought to construct a multigene mRNA expression signature to efficiently identify FGFR1-amplified estrogen receptor-positive (ER(+)) breast tumors. Five independent breast tumor series were analyzed. Genes discriminative for FGFR1 amplification were screened transcriptome-wide by receiver operating characteristic analyses. The METABRIC series was leveraged to construct/evaluate four approaches to signature composition...

BACKGROUND: Recurrence of stroke is common and it affects quality of life, mobility, and mortality rates of stroke survivors. Previous studies have shown a paradoxical association between body mass index (BMI) and post-stroke mortality, and a dose-dependent association between second-hand smoke (SHS) exposure and risk of stroke. But the associations between BMI, SHS exposure, and stroke recurrence are unclear. We aimed to examine these associations in stroke survivors. METHODS: This cross-sectional survey was done in Xi'an, Shantou, and Chongqing...

Despite advances in supportive therapy to prevent complications of sickle cell disease (SCD), access to care is not universal. Hematopoietic cell transplantation is, to date, the only curative therapy for SCD, but its application is limited by availability of a suitable HLA-matched donor and lack of awareness of the benefits of transplant. Included in this study are 1000 recipients of HLA-identical sibling transplants performed between 1986 and 2013 and reported to the European Blood and Marrow Transplant, Eurocord and the Center for International Blood and Marrow Transplant Research...

BACKGROUND: Researchers have developed approaches for the noninvasive prenatal testing of single gene diseases. One approach that allows for the noninvasive assessment of both maternally and paternally inherited mutations involves the analysis of single nucleotide polymorphisms (SNPs) in maternal plasma DNA with reference to parental haplotype information. In the past, parental haplotypes were resolved by complex experimental methods or inferential approaches, such as through the analysis of DNA from other affected family members...

BACKGROUND: Antivirals (eg, oseltamivir) are important for mitigating influenza epidemics. In 2007, an oseltamivir-resistant influenza seasonal A H1N1 strain emerged and spread to global fixation within 1 year. This event showed that antiviral-resistant (AVR) strains can be intrinsically more transmissible than their contemporaneous antiviral-sensitive (AVS) counterpart. Surveillance of AVR fitness is therefore essential. Our objective was to develop a simple method for estimating AVR fitness from surveillance data...

As the health care environment continually changes, radiologists look to the ACR's Imaging 3.0(®) initiative to guide the search for value. By leveraging new technology, a cloud-based image exchange network could provide secure universal access to prior images, which were previously siloed, to facilitate accurate interpretation, improved outcomes, and reduced costs. The breast imaging department represents a viable starting point given the robust data supporting the benefit of access to prior imaging studies, existing infrastructure for image sharing, and the current workflow reliance on prior images...
