RESUMO
Purpose: This study examined the effectiveness and safety of a home-based pulmonary rehabilitation (HBPR) program in Veterans. Methods: Patients were evaluated from five Veteran Affairs facilities that enrolled in the 12-week program. Pre- to postchanges were completed on clinical outcomes using paired t-tests and the Wilcoxon signed rank sum test. Descriptive statistics were used for patient demographics, emergency room visits, and hospitalizations. Results: Two hundred eighty-five patients with a mean age of 69.6 ± 8.3 years enrolled in the HBPR program from October 2018 to March 2020. There was a 62% (n = 176) completion rate of both pre- and post assessments. Significant improvements were detected after completion of the HBPR program in dyspnea (modified Medical Research Council: 3.1 ± 1.1 vs. 1.9 ± 1.1; p < 0.0001); exercise capacity (six-minute walk distance: 263.1 m ± 96.6 m vs. 311.0 m ± 103.6 m; p < 0.0001; Duke Activity Status Index: 13.8 ± 9.6 vs. 20.0 ± 12.7; p < 0.0001; self-reported steps per day: 1514.5 ± 1360.4 vs. 3033.8 ± 2716.2; p < 0.0001); depression (patient health questionnaire-9: 8.3 ± 5.7 vs. 6.4 ± 5.1); nutrition habits (rate your plate, heart: 45.3 ± 9.0 vs. 48.9 ± 9.2; p < 0.0001); multicomponent assessment tools (BODE Index: 5.1 ± 2.5 vs. 3.4 ± 2.4; p < 0.0001), GOLD ABCD Assessment: p < 0.0009); and quality of life (chronic obstructive pulmonary disease assessment test: 25.4 ± 7.7 vs. 18.7 ± 8.5; p < 0.0001). No adverse events were reported due to participation in HBPR. Conclusions: The HBPR program is a safe and effective model and provides an additional option to address the gap in pulmonary rehabilitation access and utilization in the Veterans Affairs.
RESUMO
Sakis (genus Pithecia) commonly live in socially monogamous groups, but data from wild populations on group dynamics and on the turnover of reproductive-age animals are rare. Here we describe the replacement of the adult male in one group of sakis in the Ecuadorian Amazon following the death of the initial resident. We use 354 h of focal behavioral data to describe differences in the spatial relationships among group members before and after the replacement and to examine changes in the rate of male-to-female grooming, aggression, scent marking and vocalization. Interactions with extra group individuals within the group's home range were more frequent during and after the replacement than before. The presence of such additional animals during periods of reproductive turnover may explain at least some reported observations of saki groups with more than 1 reproductive-age male or female.
