Bottom Line: Researchers found no evidence of an "obesity paradox" (some studies have suggested overweight or obese patients have lower mortality rates than underweight or normal weight patients) in patients with stroke.

COLUMBIA, Mo. –The majority of adults aged 65 and older remains inactive and fails to meet recommended physical activity guidelines, previous research has shown. However, these studies have not represented elders living in retirement communities who may have more access to recreational activities and exercise equipment.
Fishing vessels have a far bigger ecological footprint than previously thought, according to research which tracked the movement and behaviour of seabirds using GPS devices.
A team of scientists led by the University of Exeter discovered that northern gannets change their behaviour in response to the presence of large vessels such as trawlers, suggesting each boat can significantly influence the distribution and foraging patterns of these and other marine predators.
AUGUSTA, Ga. – Obese, Caucasian females over age 50 with diabetes and on dialysis because their kidneys have failed are among those at highest risk for the rare and deadly condition calciphylaxis, according to an analysis of the United States Renal Data System.
Calciphylaxis occurs when calcium and phosphorus bind to form a biological cement that blocks and inflames small blood vessels, putting patients at risk for major infection and skin ulcers as well as patches of dying skin, said Dr. Lu Huber, nephrologist at the Medical College of Georgia at Georgia Regents University.
LOS ANGELES (STRICTLY EMBARGOED UNTIL 7:30 A.M. EDT on JUNE 1, 2014 - ASCO Abstract No. 2005) – A multicenter team of investigators, led by researchers from the Cedars-Sinai Department of Neurosurgery, the Cedars-Sinai Maxine Dunitz Neurosurgical Institute and Dana-Farber Cancer Institute in Boston, have found in a Phase II clinical trial that an immune system-boosting therapy slowed the recurrence of glioblastoma multiforme, or GBM, the most common and deadly malignant brain tumor.
Pilocytic astrocytoma (PA) is a primarily pediatric brain tumor caused mainly by mutations in the BRAF gene. In fact, there are two specific mechanisms for activation of BRAF implicated in PA formation: by fusion of the gene with nearby gene KIAA1549 (K:B fusion) or by point mutations of the BRAF gene itself. Research presented at the American Society for Clinical Oncology (ASCO) Annual Meeting 2014 used a newly designed test for K:B fusion to show that point mutations lead to a more dangerous form of the disease than does K:B fusion.
CHICAGO — Molecular sequencing could identify ovarian cancer patients who are most likely to benefit from treatment with bevacizumab (Avastin), a Mayo Clinic-led study has found. Results of the research were presented today at the 2014 American Society of Clinical Oncology Annual Meeting.
An Emeritus Professor of medical ethics at Imperial College London will deliver a presentation at this year's Euroanaesthesia meeting titled 'Escalating care for the comorbid elderly-where do we stop?". Raanan Gillon, who is President of the UK's Institute of Medical Ethics, will argue that a patient's age should not in itself be considered an ethically relevant criterion for deciding 'where to stop'.
A systematic review and meta-analysis of hospital data worldwide, presented as this year's Euroanaesthesia meeting in Stockholm, adds further evidence that patients admitted to hospital at weekends have higher mortality than those admitted on weekdays. The study is by Dr Hiroshi Hoshijima, Tohoku University, Sendai, Japan, and colleagues.
The analysis included 72 studies from various world regions, covering 55,053,719 participants. The authors found that weekend admission was associated with increased morality of between 15% and 17% depending on the statistical technique used.
COLUMBUS, Ohio – In a head-to-head comparison of two Food and Drug Administration-approved drugs for the treatment of relapsed chronic lymphocytic leukemia (CLL), ibrutinib significantly outperformed ofatumumab as a second-line therapy, according to a multicenter interim study published in the OnLine First edition of the New England Journal of Medicine. Ibrutinib (Imbruvica) is the first drug designed to target Bruton's tyrosine kinase (BTK), a protein essential for CLL-cell survival and proliferation.
CHICAGO, IL (May 30, 2014)—Fox Chase Cancer Center researchers have carried out the first retrospective analysis of adjuvant chemotherapy's impact on overall survival in patients with stage III soft tissue sarcomas (STS), adjusted for socioeconomic status and other variables. The findings show that regardless of socioeconomic status and comorbidities, adjuvant chemotherapy improved survival by approximately 23 percent in stage III STS.
CHICAGO, IL (May 30, 2014)—More than a quarter of HIV+ patients are also infected with the Hepatitis C virus (HCV), which may complicate treatment and care decisions after a cancer diagnosis. The specifics of those complications haven't been well-researched in the past. Results from a new Fox Chase Cancer Center study on this patient population may start filling in that gap.
CHICAGO, IL (May 30, 2014)—Patients with AIDS-related lymphomas (ARL) may face an increased risk of central nervous system involvement (CNSi) compared to other lymphomas. The effect of CNSi on survival outcomes, however, hasn't been thoroughly examined until now.
A study of 338 patients with coronary artery disease has identified a gene expression profile associated with an elevated risk of cardiovascular death. Used with other indicators such as biochemical markers and family history, the profile – based on a simple blood test – may help identify patients who could benefit from personalized treatment and counseling designed to address risk factors.
Mothers of daughters with polycystic ovary syndrome (PCOS) have a significantly increased risk of death, particularly if they also have diabetes, when compared to the general population, according to new research.
