Sleep-disordered breathing linked to behavior problems in asthmatic children Posted: 13 Jul 2009 05:00 PM PDT Sleep-disordered breathing is associated with a significantly increased risk for behavior problems among children with asthma, US research shows.

CPAP improves survival in hypoxemic COPD patients with OSAS Posted: 13 Jul 2009 05:00 PM PDT Results of a Brazilian study show that continuous positive airway pressure improves survival for hypoxemic chronic obstructive pulmonary disease patients with moderate-to-severe obstructive sleep apnea syndrome.

Filaggrin gene defects linked to allergies Posted: 13 Jul 2009 05:00 PM PDT People with defects in the filaggrin gene face an increased risk for allergic sensitization and a number of allergic diseases, results of a UK study suggest.

Schizophrenia homicide rates related to total homicide rates Posted: 13 Jul 2009 05:00 PM PDT The number of homicides committed by patients with schizophrenia is strongly associated with total homicide rates, suggesting that both types of homicide have common etiological factors, show results from an Australian study.

Cognitive impairments, subsyndromal depression linked to poor long-term outcome in BD Posted: 13 Jul 2009 05:00 PM PDT Study results suggest that cognitive impairments and the amount of time spent with subsyndromal depression may be illness features associated with poorer long-term functional outcome in patients with bipolar disorder.

Negative complete compression ultrasound rules out DVT Posted: 12 Jul 2009 05:00 PM PDT A single negative complete compression ultrasound in an ambulatory office setting provides sufficient evidence to rule out deep vein thrombosis, say French researchers.

Subarachnoid hemorrhage fatality rates declining Posted: 12 Jul 2009 05:00 PM PDT Over the past three decades, case fatality rates after aneurysmal subarachnoid hemorrhage have decreased, despite the age of affected patients increasing, a meta-analysis has shown.

PSA velocity ‘does not assist prostate cancer diagnosis’ Posted: 12 Jul 2009 05:00 PM PDT Prostate-specific antigen velocity does not predict prostate cancer diagnosis or features in patients with persistently elevated PSA levels despite previously negative biopsy findings, say US scientists.

Positive surgical margin length predicts prostate cancer recurrence Posted: 12 Jul 2009 05:00 PM PDT Biochemical recurrence following robotic radical prostatectomy is predicted by the length of the positive surgical margin, with margins less than 1 mm conferring no additional risk, US study findings indicate.

Dasatinib and doxorubicin are synergistic in breast cancer cells Posted: 12 Jul 2009 05:00 PM PDT The Src inhibitor dasatinib synergizes with doxorubicin to inhibit growth, migration, and invasion of breast cancer cells, a biochemical study indicates.

Healthy diet during pregnancy linked to stronger bones in children Posted: 12 Jul 2009 05:00 PM PDT Study results show that mothers with a well balanced healthy diet during pregnancy have children with stronger bones, reflected by increases in bone size, bone mineral density, and bone mineral content.

Childhood cancer survivors at increased risk for adverse pregnancy outcome Posted: 12 Jul 2009 05:00 PM PDT Study results suggest that survivors of childhood cancer have an increased risk for postpartum hemorrhage and premature delivery, and should therefore be closely monitored during pregnancy and delivery.

TVU ‘inaccurate’ for ovarian lesion detection in asymptomatic postmenopausal women Posted: 12 Jul 2009 05:00 PM PDT Transvaginal ultrasound is an inaccurate diagnostic tool for detection of ovarian lesions in asymptomatic postmenopausal women, due to difficulty visualizing the ovaries and misidentification of benign lesions, show study results.

Omega-6 fatty acid supplements improve body fat, glucose control in obese postmenopausal women Posted: 12 Jul 2009 05:00 PM PDT Study results show that conjugated linoleic acid and safflower oil supplements can reduce body fat, increase lean tissue mass, and improve glycemic control in obese postmenopausal women with Type 2 diabetes.

High LOC, young age at menarche associated with low survival in ovarian cancer Posted: 12 Jul 2009 05:00 PM PDT Survival among women with ovarian cancer is influenced by age of menarche and total number of lifetime ovulatory cycles, show study results.

Tamoxifen does not increase ovarian cancer risk in BRCA1 mutation carriers Posted: 12 Jul 2009 05:00 PM PDT Study results show tamoxifen treatment for breast cancer does not increase the risk for ovarian cancer in BRCA1 mutation carriers.

Vaginal contraceptive ring offers good cycle control Posted: 12 Jul 2009 05:00 PM PDT Study results show that using the vaginal ring with an extended regimen for contraception offers good cycle control.

LNG-IUS prevents endometrial polyps in women using tamoxifen Posted: 12 Jul 2009 05:00 PM PDT Study results show that the levonorgestrel intrauterine system induces benign endometrial changes and prevents endometrial polyps in women taking tamoxifen for up to 4.5 years.

Childhood lipid profile changes vary by gender and ethnicity Posted: 12 Jul 2009 05:00 PM PDT The changes in lipid profile seen as children age are influenced by gender and ethnicity, report US researchers involved in Project Heartbeat!

ABCA1 function differs across smooth muscle cell types Posted: 12 Jul 2009 05:00 PM PDT Expression of the ATP-binding cassette transporter is reduced in intimal smooth muscle cells but not medial cells thereby promoting the formation of foam cells in the intima, say scientists.

Electronic decision-support ‘improves diabetes care’ Posted: 12 Jul 2009 05:00 PM PDT A personalized, web-based decision-support system can improve the management of patients with diabetes in the primary care setting, a randomized trial suggests.

Type 2 diabetes imbalances cholesterol homeostasis Posted: 12 Jul 2009 05:00 PM PDT The reciprocal relationship between cholesterol absorption and cholesterol synthesis in men with metabolic syndrome is lost in the presence of Type 2 diabetes, indicating that diabetes causes an imbalance in cholesterol homeostasis, researchers report.

Genetic variants linked to cardiac structure Posted: 12 Jul 2009 05:00 PM PDT Five genetic loci harbor common variants associated with cardiac structure and function, researchers report in the Journal of the American Medical Association.

CT angiography reduces hospital stay, costs in low-risk cardiac patients Posted: 12 Jul 2009 05:00 PM PDT Patients admitted to an emergency department with low-risk chest pain should be assessed with computed tomography angiography to help reduce length of stay and overall cost, US researchers say.
