A Bidirectional Relationship Between Chronic Stress And Sleep Problems shown by study
According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, people with chronic stress report shorter sleep duration, worse sleep quality, and more daytime functioning impairments. Conversely, daytime functioning impairments and shorter sleep duration demonstrated a predictive relationship with habitual stress complaints.

Washington Post Examines Lack Of Information About Stillbirths, Bill To Expand Data Collection
Centers for Disease Control and Prevention data show that stillbirth occurs in about one in every 160 pregnancies in the U.S., but physicians rarely warn pregnant women or their partners about the possibility, Washington Post staff writer Alan Goldenbach writes in an article discussing his experience when his wife"s pregnancy ended in stillbirth. In the U.S., the clinical definition for stillbirth is the death of a fetus after 20 weeks" gestation or weighing 350 grams if the age is unknown.There are about 26,000 stillbirths annually in the U.S., according to CDC. Goldenbach writes that this is "10 times the number of deaths attributed to sudden infant death syndrome, which has been identified as a key public health issue, and four times the incidence rate of Down syndrome, for which prenatal testing has become almost ritual." He continues that many doctors told him and his wife "that they don"t see any point in discussing stillbirth, that it"s a catch-all term for an event, and one that is frequently unexplained." Doctors contend that if they knew the causes or signs of stillbirth, they would warn patients or take preventive action, he adds. Noting that awareness of SIDS spurred research into preventive measures, Goldenbach writes that "[w]e can"t know if improved technology or more stringent standards of monitoring can lower stillbirth rates unless we do the research."Ruth Fretts, an assistant professor of obstetrics and gynecology at Harvard Medical School and chair of the scientific committee for the International Stillbirth Alliance, said, "It"s a trade-off -- you are going to frighten a lot of people" by discussing stillbirths. According to Fretts" research, the leading cause of fetal death after 28 weeks" gestation is an unexplained . Goldenbach writes, "Several doctors told us privately that many ob-gyns fear charges of malpractice following a stillbirth, leading them to avoid citing a cause of death."Stillbirth Legislation in Development Sen. Frank Lautenberg (D-N.J.) is drafting legislation similar to a stillbirth prevention bill that then-Sen. Barack Obama (D-Ill.) introduced in June 2008. According to s familiar with the bill, it will be brought to the Senate floor before the August recess. The legislation will expand stillbirth registries already in operation in Iowa and metropolitan Atlanta. The bill"s supporters hope to have as many as 12 states participating in the registry and installing a standard protocol for data collection after each stillbirth. Another provision would create a campaign to increase public awareness and strengthen grief support services, Goldenbach writes (Goldenbach, Washington Post, 7/6).

King Khalid University Hospital Links State-Of-The-Art Medical Imaging Applications With Aruba Networks' 802.11n Solution From ASACO-IT

Aruba Networks, Inc. (NASDAQ: ARUN), a global leader in wireless LANs and secure mobility solutions, announced that Saudi Arabia"s King Khalid University Hospital (KKUH), the teaching hospital of King Saud University, has deployed Aruba"s high-speed 802.11n Wi-Fi and security solutions for PACS, RIS, and HIS applications at its facilities in Riyadh. KKUH is the largest teaching hospital in the Kingdom, with more than 800 beds and 500 medical specialists. The network was deployed by ASACO-IT (Ahd Al-Saudia Company), an authorized Aruba partner in Saudi Arabia. The hospital required a single wireless network capable of simultaneously delivering staff and guest Internet access, PACS and RIS based medical imaging, HIS data, and e-mail. PACS data consist of medical images from positron emission tomography, magnetic resonance, ultrasound, computed tomography, and other medical imaging instruments. RIS is used to schedule and track radiology patients, while HIS encompasses patient, clinical, and administrative records. Data from all three systems are needed by mobile physicians and staff on an on-going basis. Aruba and ASACO-IT were selected for the project after demonstrating that the proposed 802.11n solution offered the throughput, low latency, and data integrity required for such data-intensive applications. "The large physical size of our institution demands that we deploy a Wi-Fi network that could deliver uniform, high quality coverage but would not require constant attention from the IT department," said Dr Ahmed Albarrak, Director of Computer and Informatics at King Saud University Hospitals. "Healthcare facilities are complex environments in which to transmit radio signals. We wanted the network to adjust itself, without any manual intervention, to free our staff to work on patient-facing initiatives. The Aruba network enables our PACS, RIS, HIS, and e-mail applications to run without disruption -- at a patient"s bedside, in physicians" offices, in the operating theatres. Regardless of where medical staff are working on our campus, they know they can access key services wirelessly -- and this is all accomplished without any day-to-day impact on the IT department." The reliable performance of Aruba"s 802.11n solution in such a challenging environment is attributable to the Adaptive Radio Management (ARM) technology. ARM delivers a best-in-class wireless experience by automating site surveys and using infrastructure-based controls to optimize the performance of Wi-Fi clients in real-time. Acting on their own, Wi-Fi clients do not always work cooperatively with other clients, or select the optimal band, channel, and access point. These issues are exacerbated in settings with metal shielding and reinforced concrete walls such as imaging centers and laboratories. By controlling how Wi-Fi clients interact, ARM ensures that data, voice, and video applications have sufficient network res, including airtime, to operate properly. "The critical nature of healthcare-related applications means that their wireless networks must be fast, agile, and very reliable -- all strengths of Aruba"s 802.11n solution," said Ammar Enaya, sales director of Aruba MEA. "802.11n has the potential to provide pervasive coverage across a large and varied site such as KKUH, however, by itself 802.11n is not enough. Automatic management of the RF environment, identity-based security for data integrity, and centralized management to minimize IT overhead are all needed to enable 802.11n to reach its full potential. Aruba integrates all three within a single system, and that is what allows customers like KKUH to rely on Wi-Fi as their primary form of network access." Aruba Networks
