INTRODUCTION: Recent genome-wide association studies have identified 103 adult obesity risk loci; however, it is unclear if these findings are relevant to East-Asian childhood body mass index (BMI) levels. METHODS AND RESULTS: We evaluated for paediatric obesity associations at these risk loci utilizing genome-wide data from Chinese childhood subjects in the Singapore Cohort study Of the Risk factors for Myopia study (N = 1006). A weighted gene-risk score of all adult obesity risk loci in the Singapore Cohort study Of the Risk factors for Myopia study showed strong associations with BMI at age 9 (p-value = 3...

Symbiotic nitrogen (N) fixation is the major N input to many ecosystems. Although temperate forests are commonly N limited, symbiotic N-fixing trees ("N fixers") are rare and decline in abundance as succession proceeds-a challenging paradox that remains unexplained. Understanding demographic processes that underlie N fixers' rarity and successional decline would provide a proximate answer to the paradox. Do N fixers grow slower, die more frequently, or recruit less in temperate forests? We quantified demographic rates of N-fixing and non-fixing trees across succession using U...

In cases of Dengue fever, late hospital admission can lead to treatment delay and even death. In order to improve early disease notification and management, it is essential to investigate the factors affecting the time of admission of Dengue cases. This study determined the factors associated with the time of admission among notified Dengue cases. The study covered the period between 2008 and 2014 in Region VIII, Philippines. The factors assessed were age, sex, hospital sector, hospital level, disease severity based on the 1997 WHO Dengue classification, and period of admission (distinguishing between the 2010 Dengue epidemic and non-epidemic time)...

BACKGROUND: Neonatal hypoglycaemia is common, affecting up to 15% of newborns, and can cause brain damage. Currently, there are no strategies, beyond early feeding, to prevent neonatal hypoglycaemia. Our aim was to determine a dose of 40% oral dextrose gel that will prevent neonatal hypoglycaemia in newborn babies at risk. METHODS AND FINDINGS: We conducted a randomised, double-blind, placebo-controlled dose-finding trial of buccal dextrose gel to prevent neonatal hypoglycaemia at two hospitals in New Zealand...

For musculoskeletal complaints (MSCs) among adults, several risk factors are known, but the most important determinant is an earlier episode of MSCs. Research has shifted to younger ages, showing a high prevalence of MSCs among children and adolescents. Our purpose was to evaluate the prevalence of MSCs among those growing up from age 11 to 14 and to explore the role of several sociodemographic, growth and development, psychosocial, and lifestyle factors. Data collected at age 11 (n = 2651) and age 14 (n = 2522) in the ongoing Dutch Prevention and Incidence of Asthma and Mite Allergy (PIAMA) birth cohort study were used...

In obstetric practice, each pregnant woman presents with a composite of maternal and fetal characteristics that can alter the risk of significant harm without cesarean intervention. The hospital's availability of resources and the obstetrician's training, experience, and skill level can also alter the risk of significant harm without cesarean intervention. This paper proposes a clinical ethical framework that takes these clinical and organizational factors into account, to promote a deliberative rather than simplistic approach to decision-making and counseling about cesarean delivery...

Heart valves are currently under thorough investigation in tissue engineering (TE) research. Mechanical and biological heart valve prostheses which are recently used have several shortcomings. While allogenic and xenogenic biological prostheses are related to graft rejection, degeneration and thrombosis, resulting in a high rate of reoperation. Mechanical prostheses on the other hand are based on metallic, carbon, and polymeric components, and require continuous treatment with anticoagulant, which result in adverse reactions, e...

Allergic rhinitis (AR) is a common chronic inflammatory condition of the nasal mucosal tissue. Platycodin D (PLD), a triterpenoid saponin isolated from the root of Platycodon grandiflorum, has anti-inflammatory effects in a mouse model of allergic asthma. However, the anti-inflammatory effects of PLD in the nasal mucosa have not been deeply investigated. The objective was to investigate the effect of PLD on inflammatory cytokines and mucus production from nasal epithelial cells. Our study showed that PLD inhibited the levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) and eotaxin in interleukin (IL)-13-stimulated RPMI2650 cells...

As indicated by research on the long-term effects of adverse childhood experiences (ACEs), maltreatment has far-reaching consequences for affected children. Effective prevention measures have been elusive, partly due to difficulty in identifying vulnerable children before they are harmed. This study employs Risk Terrain Modeling (RTM), an analysis of the cumulative effect of environmental factors thought to be conducive for child maltreatment, to create a highly accurate prediction model for future substantiated child maltreatment cases in the City of Fort Worth, Texas...

Animals with hemophilia are models for gene therapy, factor replacement, and inhibitor development in humans. We have actively sought dogs with severe hemophilia A that have novel factor VIII mutations unlike the previously described factor VIII intron 22 inversion. A male Old English Sheepdog with recurrent soft-tissue hemorrhage and hemarthrosis was diagnosed with severe hemophilia A (factor VIII activity less than 1% of normal). We purified genomic DNA from this dog and ruled out the common intron 22 inversion; we then sequenced all 26 exons...

Preoperative diagnosis of ischemic bowel in patients with small bowel obstruction (SBO) is a clinical challenge. The aim of this study was to identify preoperative variables associated with ischemic bowel found at operative exploration. We performed a 5-year retrospective review of patients admitted to a university affiliated, county funded hospital who underwent exploratory laparoscopy or laparotomy for SBO. Patients were excluded if they had a known preoperative malignancy or hernia on physical examination...

Atopic dermatitis (AD) is a complex, chronic inflammatory skin disorder affecting more than 10% of UK children and is a major cause of occupation-related disability. A subset of patients, particularly those with severe AD, are persistently colonised with Staphylococcus aureus (S. aureus) and exacerbation of disease is commonly associated with this bacterium by virtue of increased inflammation and allergic sensitisation, aggravated by skin barrier defects. Understanding the complex biology of S. aureus is an important factor when developing new drugs to combat infection...

Muscle contractures are common in patients with central motor lesions, but the mechanisms responsible for the development of contractures are still unclear. Increased or decreased neural activation, protracted placement of a joint with the muscle in a short position and muscle atrophy have been suggested to be involved, but none of these mechanisms are sufficient to explain the development of muscle contractures alone. Here we propose that changes in tissue homeostasis in the neuro-muscular-tendon-connective tissue complex is at the heart of the development of contractures, and that an integrated physiological understanding of the interaction between neural, mechanical and metabolic factors, as well as genetic and epigenetic factors, is necessary in order to unravel the mechanisms that result in muscle contractures...

Infertility, defined by the inability of conceiving a child after one year is estimated to concern approximately 50 million couples worldwide. As the male gamete is readily accessible and can be studied by a simple spermogram it is easier to subcategorize male than female infertility. Subjects with a specific sperm phenotype are more likely to have a common origin thus facilitating the search for causal factors. Male infertility is believed to be often multifactorial and caused by both genetic and extrinsinc factors, but severe cases of male infertility are likely to have a predominant genetic etiology...

Alzheimer's disease (AD) is the most common type of progressive neurodegenerative disorder, and is responsible for the most common form of dementia in the elderly. Inflammation occurs in the brains of patients with AD, and is critical for disease progression. In the present study, the effects of rapamycin (RAPA) on neuroinflammation lipopolysaccharide (LPS)-induced were investigated. SH‑SY5Y human neuroblastoma cells were treated with 20 µg/ml LPS and 0.1, 1 or 10 nmol/l RAPA, and were analyzed at various time points (6, 12 and 24 h)...
