    Patients’ blood oxygen saturation is an important parameter to monitor during surgery, but it’s currently clinically impossible if the patient is still in the womb of its mother. At Rice University a team of engineering students has developed a prototype device, called WombOX, that is a pulse oximeter that can be delivered inside the womb and gently attached to the arm or leg of a fetus.

    The pulse oximeter is integrated with a nitinol wire loop that is compressed when inside the delivery sheath. Once pushed out and exposed to the heat of the body, the nitinol expands and the loop opens up. It is then wrapped around the arm or leg of the fetus and tightened. LEDs within the device work along with a light detector to sense blood oxygenation just like in existing oximeters. It can be brought back into the sheath and removed following a procedure.

    Here’s a video with the Rice student team discussing the device.

    The prevalence of surgically confirmed endometriosis is less than 25 percent among women undergoing hysterectomy for chronic pelvic pain, according to a study published in the June issue of Obstetrics & Gynecology.

    Erika L. Mowers, M.D., from the University of Michigan in Ann Arbor, and colleagues conducted a retrospective cohort study involving 9,622 women who underwent laparoscopic or abdominal hysterectomy for benign indications. The prevalence of surgically confirmed endometriosis was determined by review of the operative report and surgical pathology for the entire cohort and for subgroups with or without chronic pelvic pain or endometriosis.

    The researchers found that 15.2 percent of the patients undergoing hysterectomies had endometriosis at the time of hysterectomy. Fewer than one in four of the 3,768 women with a preoperative indication of chronic pelvic pain had endometriosis (21.4 percent). Many of those with preoperative indication of endometriosis did not actually have endometriosis at the time of hysterectomy (42.8 percent). Among women without preoperative indication of chronic pelvic pain or endometriosis, the rate of unexpected endometriosis was 8 percent. Among the women with a preoperative indication of chronic pelvic pain, endometriosis was more common in those with younger age, white race, and lower body mass index and for those who had previously failed another treatment.

    "Fewer than 25 percent of women undergoing laparoscopic or abdominal hysterectomy for chronic pelvic pain have endometriosis at the time of surgery," the authors write.

    (HealthDay) - Risk factors have been identified for 30-day readmission following hysterectomy, according to a study published in the May issue of the American Journal of Obstetrics & Gynecology.

    Malinda S. Lee, M.D., from Brigham and Women's Hospital/Massachusetts General Hospital in Boston, and colleagues examined risk factors for 30-day readmission following hysterectomy for 1,649 women with nongravid hysterectomies conducted from 2008 through 2010 (1,009 for benign indications and 640 for malignancy).

    The researchers found that 6 percent of the women were readmitted within 30 days, with a mean time to readmission of 13 days. For women undergoing hysterectomy with benign indications, the odds of readmission were increased with a history of a laparotomy (including cesarean delivery) (adjusted odds ratio [aOR], 2.12) and a perioperative complication (aOR, 2.41).

    For women undergoing hysterectomy for malignancy, the odds of readmission were increased with an American Society of Anesthesiologists Physical Status Classification of III or IV (aOR, 1.92), a longer length of initial hospitalization (three days: aOR, 7.83), and an estimated blood loss of >500 mL (aOR, 3.29); the risk of readmission was reduced for women who underwent a laparoscopic hysterectomy (aOR, 0.32) and for those who were discharged on postoperative day one (aOR, 0.16).

    "These findings can serve to develop interventions to allow gynecologic surgeons to appropriately stratify patients at highest risk for readmission at the time of hysterectomy," the authors write.

    Campaign urges health care professionals and patients and loved ones to keep hands clean

    MONDAY, May 9, 2016 (HealthDay News) -- The U.S. Centers for Disease Control and Prevention has introduced a new campaign, "Clean Hands Count," to encourage health care professionals, patients, and patients' families to keep their hands clean in order to prevent health care-associated infections.

    Studies show that some health care professionals do not follow CDC hand hygiene recommendations, with health care professionals cleaning their hands less than half of the time they should.

    The new campaign promotes health care provider adherence to CDC recommendations, addressing misperceptions about hand hygiene, such as the belief that alcohol-based hand sanitizer contributes to antibiotic resistance and is damaging to hands versus soap and water. Patients and their loved ones should check whether their health care team members have washed their hands.

    "Patients depend on their medical team to help them get well, and the first step is making sure health care professionals aren't exposing them to new infections," CDC Director Tom Frieden, M.D., M.P.H., said in a statement. "Clean hands really do count and in some cases can be a matter of life and death."
