BACKGROUND Neuraminidase inhibitors were widely used during the 2009-10 influenza A H1N1 pandemic, but evidence for their effectiveness in reducing mortality is uncertain. We did a meta-analysis of individual participant data to investigate the association between use of neuraminidase inhibitors and mortality in patients admitted to hospital with pandemic(More)
OBJECTIVE Vitamin D insufficiency is prevalent in various populations worldwide but with scarce data on physically active individuals. Vitamin D is important to athletes, affecting bone mass, immunity, and physical performance. This study evaluated the prevalence of vitamin D insufficiency and deficiency among young athletes and dancers. DESIGN(More)
BACKGROUND Attention deficit-hyperactivity disorder (ADHD) is the most common neuro-developmental disorder in childhood. Its pharmacologic treatment mostly includes methylphenidate, yet many parents seek alternative, "natural," therapeutic options, commonly omega-3 fatty acids. Previous studies of supplementation with fish oil or long-chain omega-3 fatty(More)
INTRODUCTION Colchicine is used mainly for the treatment and prevention of gout and for familial Mediterranean fever (FMF). It has a narrow therapeutic index, with no clear-cut distinction between nontoxic, toxic, and lethal doses, causing substantial confusion among clinicians. Although colchicine poisoning is sometimes intentional, unintentional toxicity(More)
BACKGROUND Selective serotonin reuptake inhibitors (SSRI) are commonly used to treat depression in pregnant women. Several adverse effects of prenatal SSRI exposure on the offspring have been described, including decreased growth. SSRI use by adults decreases bone mineral density, but this effect had not been examined in infants. AIM To examine growth(More)
BACKGROUND Kingella kingae is a gram-negative coccobacillus, increasingly recognized as an invasive pediatric pathogen. To date, only few small series of invasive K. kingae infections have been published, mostly from single medical centers. A nationwide multicenter study was performed to investigate the epidemiologic, clinical, and laboratory features of(More)
Observational studies identified associations between vitamin D insufficiency (serum 25(OH)D < 30ng·ml-1) and risk of upper respiratory infection (URI). Swimmers are highly prone to URIs, which might hinder their performance. The aim of this study was to examine if vitamin D3 supplementation reduces URI burden in vitamin D-insufficient swimmers. Fifty-five(More)
We performed a cross-sectional study in 450 nonreferred preschool children aged 4 to 6 years to assess the association between hyperactivity/inattention with adiposity and lifestyle characteristics. Measurements included scores of hyperactivity/inattention, adiposity, objectively measured physical activity, television viewing, and eating habits. Higher(More)
INTRODUCTION Studies have shown that physical activity (PA) is superior to many other environmental factors in determining bone mineral density (BMD), but none has examined the independent relationship between PA and vitamin D status. PURPOSE The aim of this study was to assess the relationship among amount of PA, vitamin D (25(OH)D), and BMD. METHODS A(More)
QUESTION Several pregnant patients have asked recently whether media reports of children's intelligence quotients' increasing with increased intake of essential fatty acids are meaningful enough to be worth the effort of supplementation. What advice should they be given? ANSWER Existing evidence from interventional studies is sparse and conflicting and(More)
