Georgia Receives More Than $60M In Ryan White Funding
Georgia has received $63.9 million in Ryan White Program grants to fund treatment and other services for people living with HIV, the Atlanta Journal-Constitution reports. Grant recipients include county health departments and community organizations. The funding will be used to provide outpatient health services, health insurance coverage and support services, such as transportation and housing. According to the Journal-Constitution, more than $1.79 billion in Ryan White funding was allocated nationwide. Several HIV/AIDS organizations said that the funding is necessary to continue providing services for people living with the disease. Tracy Elliot, executive director of AID Atlanta, said that the funding is "critical," noting that more than 18,000 HIV/AIDS cases have been reported in Georgia. He continued, "We would have a lot of deaths without [the funding]. There would be significantly more illnesses without it and significantly more transmission of the disease without it." According to Elliot, "[m]edical treatment and medications are of no value if people cannot have access to them" (Poole, Atlanta Journal-Constitution, 5/19).

A Potential Treatment For Gastric Motility Disorders

GES or pacing has been under investigation as a potential therapy for gastrointestinal motility disorders. Conventionally, GES is performed using a single pair of electrodes or single-channel GES. However, few studies have investigated the effects of two-channel GES with trains of pulses on gastric motility, such as gastric slow waves and gastric emptying. The research team led by Prof. Chen from University of Texas Medical Branch studied the effects of two-channel GES with trains of pulses on gastric slow waves and gastric emptying in healthy dogs. Most previous studies showed that long pulse GES was able to entrain gastric slow waves in human and animals. None of previous studies have investigated the effect of GES with trains of pulses on gastric slow waves. It has been indicated that GES with trains of short pulses was able to improve symptoms, such as nausea and vomiting of gastroparesis, but was not capable of entraining gastric slow waves or normalizing gastric dysrhythmias. In this study, we have shown that GES with trains of pulses is able to entrain gastric slow waves when the pulses in the train are of a width of 4ms or higher. Recently, a few studies were performed to investigate the efficiency of multi-channel GES on gastric emptying and entrainment of slow waves. Some studies indicated that multi-channel stimulation with long pulses was more efficient than single-channel stimulation for the entrainment of slow waves and the acceleration of gastric emptying. To date, no study has investigated the effects of multi-channel GES with trains of pulses on gastric emptying. In our experiment, we found two-channel but not single-channel GES with trains of pulses significantly accelerated gastric emptying. The results of our study suggest that 2-channel GES with trains of pulses may be applicable for the treatment of gastroparesis and normalization of gastric dysrhythmia. GES with trains of pulses is technically more attractive than long pulse GES. Currently, most of commercially available implantable stimulators use trains of pulses. However, none of available implantable stimulators are capable of generating pulses with a width equal to or larger than 4ms. Therefore, new hardware design and development are needed.
