Patient Partnerships Transforming Sleep Medicine Research and Clinical Care: Perspectives from the Sleep Apnea Patient-Centered Outcomes Network.

Due to an ongoing recent evolution in practice, sleep medicine as a discipline has been compelled to respond to the converging pressures to reduce costs, improve outcomes, and demonstrate value. Patient "researchers" are uniquely placed to participate in initiatives that address the specific needs and priorities of patients and facilitate the identification of interventions with high likelihood of acceptance by the "customer." To date, however, the "patient voice" largely has been lacking in processes affecting relevant policies and practice guidelines.

Maximal cardiac output determines 6 minutes walking distance in pulmonary hypertension.

Purpose: The 6 minutes walk test (6MWT) is often shown to be the best predictor of mortality in pulmonary hypertension (PH) probably because it challenges the failing heart to deliver adequate cardiac output. We hypothesised that the 6MWT elicits maximal cardiac output as measured during a maximal cardiopulmonary exercise testing (CPET).

Methods: 18 patients with chronic thromboembolic pulmonary hypertension (n = 12) or pulmonary arterial hypertension (n = 6) and 10 healthy subjects performed a 6MWT and CPET with measurements of cardiac output (non invasive rebreathing device) before and directly after exercise.

Acute stress reactions following the assassination of Mexican presidential candidate Colosio.

Considerable evidence suggests that exposure to traumatic events increases the risk of developing anxiety-spectrum disorders in response to later traumatization. We conducted a survey in Guadalajara, Mexico to assess factors associated with acute stress reactions to the assassination of a political figure. Participants included 86 adults who completed the Stanford Acute Stress Reaction Questionnaire (SASRQ) and measures of the perceived impact of the assassination, exhibited emotional behavior following the assassination, and had exposure to a specific prior disaster (a gas pipeline explosion).
