• 19:24 Authors with financial conflicts reporting negative outcomes in major orthopaedic journals

  Read the story at PhysOrg
  In a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers completed a systematic review of three major orthopaedic journals – the Journal of Bone and Joint Surgery (American and British editions) and the Journal of Arthroplasty (JOA) – for all articles related to metal-on-metal total hip replacement between October 1999 and May 2011. As a conflict of interest can increase the potential for research bias and study outcomes, the AAOS and major orthopaedic journals require all presenters and authors to disclose potential professional conflicts.

• 19:24 Drug halts organ damage in inflammatory genetic disorder

  Read the story at PhysOrg
  A new study shows that Kineret (anakinra), a medication approved for the treatment of rheumatoid arthritis, is effective in stopping the progression of organ damage in people with neonatal-onset multisystem inflammatory disease (NOMID). This rare and debilitating genetic disorder causes persistent inflammation and ongoing tissue damage. The research was performed by scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health.

• 19:24 Hovering not hard if you're top-heavy, researchers find

  Read the story at PhysOrg
  Top-heavy structures are more likely to maintain their balance while hovering in the air than are those that bear a lower center of gravity, researchers at New York University's Courant Institute of Mathematical Sciences and Department of Physics have found. Their findings, which appear in the journal Physical Review Letters, are counter to common perceptions that flight stability can be achieved only through a relatively even distribution of weight—and may offer new design principles for hovering aircraft.

• 19:24 Molecular profiling reveals differences between primary and recurrent ovarian cancers

  Read the story at PhysOrg
  There is a need to analyze tumor specimens at the time of ovarian cancer recurrence, according to a new study published in Molecular Cancer Therapeutics. Researchers used a diagnostic technology called molecular profiling to examine the differences in the molecular characteristics of primary and recurrent ovarian tumors and found significant changes for some biomarkers. This is the first study that examined potential differences in a broad biomarker panel in patient-matched primary versus recurrent ovarian cancers and underscores the importance of analyzing the most current tumor tissue in order to make the most informed decisions about treatment for recurrence.

• 19:24 Night, weekend delivery OK for babies with birth defects

  Read the story at PhysOrg
  Weekday delivery is no better than night or weekend delivery for infants with birth defects, according to a new study presented today at The Pregnancy Meeting, the Society for Maternal-Fetal Medicine's annual conference. The finding is good news for all parties – moms, babies and healthcare teams – and suggests that this high-risk population of women should deliver when their bodies are ready to deliver, regardless of the day or time.

• 17:24 Domestic consumption main contributor to Africa's growing e-waste

  Read the story at PhysOrg
  West Africa faces a rising tide of e-waste generated by domestic consumption of new and used electrical and electronic equipment, according to a new United Nations report. Domestic consumption makes up the majority (up to 85 percent) of waste electronic and electrical equipment produced in the region, according to the study. The E-waste problem in West Africa is further exacerbated by an ongoing stream of used equipment from industrialized countries, significant volumes of which prove unsuitable for reuse.
