• 06:00 Rothman at Jefferson researchers show benefits of local anesthesia after knee replacement surgery

  Read the story at EurekAlert
  Researchers at the Rothman Institute at Jefferson have shown that local anesthesia delivered through a catheter in the joint, intraarticularly, may be more beneficial than traditional opioids such as morphine and Oxycontin for pain management following total knee replacement surgery.

• 06:00 Sleep breathing machine shows clear benefits in children with sleep apnea

  Read the story at EurekAlert
  Children and adolescents with obstructive sleep apnea had substantial improvements in attention, anxiety and quality of life after treatment with positive airway pressure -- a nighttime therapy in which a machine delivers a stream of air through a mask into the nose. While commonly used in adults with obstructive sleep apnea, this therapy has seldom been studied in children.

• 06:00 Sonic Cradle lands spot in TED exhibition

  Read the story at EurekAlert
  A Simon Fraser University graduate student project that melds music, meditation and modern technology has landed a rare spot as an exhibit at TEDActive 2012 in Palm Springs, Calif., this month.Jay Vidyarthi's project, Sonic Cradle, allows individuals to use their breathing to shape musical sounds while they sit suspended in a totally dark chamber. The experience is described as "meditation for the non-meditator."

• 06:00 Study finds in women with prior cesarean, optimal gestational age for elective delivery is week 39

  Read the story at EurekAlert
  In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that indicate that for women with prior delivery via cesarean section the optimal timing of elective delivery for mother and baby is 39 weeks even after consideration of the risk with continuing pregnancy.

• 06:00 Study finds massively parallel sequencing can detect fetal aneuploidies, including Down syndrome

  Read the story at EurekAlert
  In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that indicate that massively parallel sequencing can be used to diagnose fetal aneuploidies, including Down syndrome, Edwards syndrome, Patau syndrome and Turner syndrome.

• 06:00 Study finds preterm labor diagnostic markers not universal, diagnosis and interventions should not be generalized

  Read the story at EurekAlert
  In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that indicate that preterm birth interventions should be tailored for underlying risk factors and pathways.

• 06:00 Study finds that red blood cell transfusion decreases fatigue in women with acute postpartum anemia

  Read the story at EurekAlert
  In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that show that in women with acute postpartum anemia, due to excessive blood loss during delivery, red blood cell transfusion led to a statistically significant decrease in physical fatigue.

• 06:00 Study weighs risks and benefits of birthing facilities

  Read the story at EurekAlert
  In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that indicate that the risk of obstetric intervention is lower for women who deliver or intend to deliver outside of hospitals, but there are some higher risks for newborns intended for home births compared to hospital births.

• 06:00 To avoid early labor and delivery, weight and diet changes not the answer

  Read the story at EurekAlert
  One of the strongest known risk factors for spontaneous preterm birth -- any birth that occurs before the 37th week of pregnancy, often without a known cause -- is already having had one. For women in this group who would like to avoid this scenario in their second pregnancy, focusing on weight and dietary changes may not be the best strategy. A new study found no connection between weight gain and the risk of repeat preterm birth.

• 06:00 5-10 percent corn yield jump using erosion-slowing cover crops shown in ISU study

  Read the story at EurekAlert
  The most recent annual results from a four-year Iowa State University study by Ken Moore, Distinguished Professor of agronomy and primary investigator on the project, reveal that using cover crops can lead to higher yields -- by as much as 10 percent . The results are the best yet in the ongoing research. Moore plans to continue on the trials for at least one more growing season.

• 06:00 60 percent of Spanish adolescents state they do not take drugs and rarely drink alcohol

  Read the story at EurekAlert
  Despite the cliches surrounding the habits of adolescents, the results of a study by the University of Seville show that most young people do not fit the risk profile of taking substances. Some 60 percent of Spaniards aged 13 to 18 say they do not take drugs and rarely drink alcohol -- only in moderation -- and at the same time, less than 10 percent admit to have taken some form of illegal drug.

• 06:00 A novel method for simultaneously measuring blood pressure and arterial stiffness

  Read the story at EurekAlert
  Arterial stiffness due to is a major contributor to cardiovascular disease but is very difficult to measure. A new method for measuring arterial stiffness has been reported in BioMed Central's open access journal BioMedical Engineering OnLine. This simple, non-invasive, calculation is able to interpret standard oscillometric measurements to quantify both arterial stiffness and blood pressure simultaneously.

• 06:00 Amazing skin gives sharks a push

  Read the story at EurekAlert
  Shark skin has long been known to improve the fish's swimming performance by reducing drag, but now George Lauder and Johannes Oeffner from Harvard University show that in addition, the skin generates thrust, giving the fish an extra boost. The duo also discovered that Speedo's shark skin-inspired Fastskin® FS II fabric surface does not improve swimming speed, although they point out that the figure hugging costumes probably enhance performance in other ways.

• 06:00 Army studies: High recurrence of shoulder instability, better arthroscopic repair outcomes

  Read the story at EurekAlert
  Two studies on shoulder instability in a military population were presented today by US Army sports medicine surgeons at the American Academy of Orthopaedic Surgeons' annual meeting. Findings in one study suggest patients with a self-reported history of shoulder instability are far more likely to experience future instability, while the second study outlined key factors associated with surgical failure and concluded that arthroscopic surgical intervention has better outcomes than an open shoulder repair.

  Read the story at EurekAlert
  An automated on/off feature built into insulin pump systems can suspend insulin delivery when it detects low blood glucose levels (via continuous glucose monitoring), significantly reducing the severity and duration of hypoglycemia in individuals with Type 1 diabetes, according to a study published in Diabetes Technology & Therapeutics, a peer-reviewed journal from Mary Ann Liebert Inc.
