Cobalt-associated asthma investigated Posted: 29 Mar 2010 05:00 PM PDT The risk for asthma caused by occupational exposure to cobalt increases with increasing levels of exposure, and respiratory symptoms may persist after exposure has ceased, Finnish study results show.

COPD prevalence in Canada increasing Posted: 29 Mar 2010 05:00 PM PDT The prevalence of chronic obstructive pulmonary disease has increased significantly in recent years, particularly among women, results from a Canadian study suggest.

Vitamin D supplements may reduce childhood influenza A risk Posted: 29 Mar 2010 05:00 PM PDT Vitamin D supplementation may reduce the risk for seasonal influenza A infection and asthma attacks in children, study results suggest.

Subjective working memory test validated in schizophrenia Posted: 29 Mar 2010 05:00 PM PDT Patients with schizophrenia who report working memory deficits on a self-assessed scale show reductions in left and right frontal lobe volumes relative to their peers with fewer deficits, a magnetic resonance imaging study has shown.

Criteria for childhood bipolar disorder diagnosis questioned Posted: 29 Mar 2010 05:00 PM PDT The incidence of DSM-IV-defined bipolar disorder is very low in children and adolescents, according to the results of an epidemiological study.

Researchers create novel antithrombotic agent Posted: 28 Mar 2010 05:00 PM PDT A selective factor XIIa inhibitor created by fusing recombinant human albumin with Infestin-4, a protein cloned from the midgut of a blood-sucking insect, has the potential to protect patients from thrombotic events without increased bleeding risk, German researchers report.

Mexican Americans with stroke less likely than Whites to call emergency services Posted: 28 Mar 2010 05:00 PM PDT Mexican Americans are 40% less likely than non-Hispanic White Americans to call 9-1-1 and be taken to hospital by ambulance for stroke, according to the findings of a population-based study in south Texas.

Prostate brachytherapy effective intermediate- as well as low-risk cancer treatment Posted: 28 Mar 2010 05:00 PM PDT Research has confirmed the success of permanent prostate brachytherapy for low-risk prostate cancer, and indicates its efficacy in intermediate-risk cases.

High-dose chemotherapy may compromise postoperative radiotherapy delivery Posted: 28 Mar 2010 05:00 PM PDT Patients treated with high-dose chemotherapy for breast cancer are less likely to initiate and complete local-regional radiotherapy than those treated with intermediate-dose chemotherapy, study findings indicate.

Women with infertility at risk for sexual dysfunction Posted: 28 Mar 2010 05:00 PM PDT Female infertility is associated with an increased risk for sexual dysfunction, say researchers, who call for this complex interrelationship to be investigated further.

Acupuncture ‘without benefit’ during assisted conception Posted: 28 Mar 2010 05:00 PM PDT Acupuncture and Chinese herbal medicine do not enhance the effectiveness of fertility treatment, a review of the available evidence has found.

Ectopic pregnancy more common after fresh than frozen or donor ET Posted: 28 Mar 2010 05:00 PM PDT Fresh embryo transfer after controlled ovarian stimulation results in a higher rate of ectopic pregnancy than cycles using donated oocytes or thawed embryos, say researchers.

Cumulative pregnancy rates are best indicator for overall IVF success Posted: 28 Mar 2010 05:00 PM PDT Cumulative pregnancy rates after one cycle of controlled ovarian hyperstimulation may be a better marker for IVF success than fresh or frozen embryo transfer rates alone, say researchers.

‘Good prognosis donors’ improve success of ART Posted: 28 Mar 2010 05:00 PM PDT Study results have revealed a subset of best-prognosis oocyte donors who produce a higher oocyte-to-baby ratio than standard oocyte donors, raising the possibility of improved assisted reproductive technology success rates.

<i>APOC3</i> variants linked to NAFLD and insulin resistance Posted: 28 Mar 2010 05:00 PM PDT Polymorphisms in the apolipoprotein C3 gene are linked to non alcoholic fatty liver disease and insulin resistance, report US researchers.

Pre-eclampsia could be a marker of future cardiovascular or metabolic disease Posted: 28 Mar 2010 05:00 PM PDT Development of pre-eclampsia may act as a marker for future cardiovascular or metabolic disease, say Chinese researchers.

Soluble plant fiber can lower LDL cholesterol in hypercholesterolemic patients Posted: 28 Mar 2010 05:00 PM PDT A soluble plant fiber can lower low-density lipoprotein cholesterol levels more than placebo in patients with mild-to-moderate hypercholesterolemia, trial findings suggest.

<i>APOC3</i> variants linked to NAFLD and insulin resistance Posted: 28 Mar 2010 05:00 PM PDT Polymorphisms in the apolipoprotein C3 gene are linked to non alcoholic fatty liver disease and insulin resistance, report US researchers.

Bariatric surgery resolves Type 2 diabetes in many moderately obese patients Posted: 28 Mar 2010 05:00 PM PDT Results from a systematic review suggest that bariatric surgery resolves symptoms of Type 2 diabetes in most patients with a body mass index below 35 kg/m2, without excessive weight loss.

Coronary arteries develop from reprogrammed venous endothelial cells Posted: 28 Mar 2010 05:00 PM PDT Scientists have discovered that coronary arteries arise mainly from venous endothelial cells during development of the embryonic heart.

Study finds no significant effect of PPI-clopidogrel interaction on CV events Posted: 28 Mar 2010 05:00 PM PDT Another observational study has found no clear evidence that use of a proton pump inhibitor blunts the ability of clopidogrel to protect against cardiovascular events.
