Provider, Staff, and Patient Perspectives on medical Visits Using Clinical Video Telehealth: A Foundation for Educational Initiatives to Improve Medical Care in Telehealth.

Clinical Video Telehealth (CVT) use is increasing and allows geographically separated care; however, this separation may affect participants behaviors. Using semi-structured in-depth interviews, we asked CVT nurse practitioners (NP), staff and patients at a VA Medical Center about perspectives on how CVT effects communication and identified three themes. They remarked on the complexity of scheduling appointments, local barriers to care, and acutely ill patients. NPs discussed how CVT altered sensory collection during the physical exam and differences in building provider-patient relationships. Patients perceptions mirrored these themes. NPs identified how CVT requires different workflow, behaviors, and use of their senses. Patients expressed similar concerns with CVT.

Superoxide dismutase failed to attenuate allergen-induced nasal congestion in ragweed-sensitized dogs.

We hypothesized that augmentation of antioxidant defenses with exogenous superoxide dismutase (SOD), an enzyme that provides an initial defense against oxidative injury, would attenuate allergen-induced nasal congestion in the canine model of allergic rhinitis. Nasal congestion was evaluated by the measurements of nasal resistance and the volume of the nasal passage. In five nonsensitized dogs, 30,000 U of SOD from bovine erythrocytes delivered by aerosol to the nasal passages before histamine challenge reduced the histamine-induced nasal congestion. At 30 min postchallenge, nasal resistance was 1.14 +/- 0.2 cmH2O.l(-1).min(-1) in the saline pretreatment study vs. 0.36 +/- 0.02 cmH2O.l(-1).min(-1) in the SOD pretreatment study (P < 0.05), and volume of nasal passage was 10.9 +/- 0.5 cm3 vs. 17.4 +/- 1.3 cm3 (P < 0.05), respectively. In five sensitized dogs, however, neither an analogous pretreatment with SOD nor intranasal aerosolized pretreatment with 30,000 U of SOD conjugated to polyethylene glycol attenuated ragweed-induced nasal congestion. Also, systemic application of SOD did not attenuate responses to challenges with histamine and ragweed in nonsensitized and sensitized dogs, respectively. The antioxidant-induced attenuation of nasal congestion in nonsensitized dogs confirms validity of the model and indicates the involvement of free radical-mediated damage in the genesis of the histamine-induced congestion. In sensitized dogs, the data do not support the hypothesis that oxidative stress is a clinically significant component of acute ragweed-induced nasal congestion. The data do not support the use of SOD for acute protection against allergic rhinitis.
