- Physical activity for obstructive sleep apnea after stroke? A pilot study assessing the contribution of body fluids(2023) FRANGE, Cristina; ELIAS, Rosilene Motta; SIENGSUKON, Catherine; COELHO, Fernando Morgadinho SantosPurpose Obstructive sleep apnea (OSA) and physical inactivity are common after stroke. Physical inactivity can lead to/or exacerbate edema following stroke, and the resultant overnight fluid shift may increase the risk of OSA. We aimed to investigate the effect of physical activity on nocturnal rostral fluid shift, sleep pattern, and edematous state of hemiparetic patients. Methods Neck circumference (tape measured) and arms, legs, and trunk fluid volume (bioelectrical impedance spectrum analyzer) were measured before and after 2 polysomnography (PSG) examinations. In the lab, a whole night PSG was performed after the intervention. The intervention consisted of inactivity (lying down and sitting) or activity (standing, performing calf muscle contractions while standing, walking, and climbing stairs) between 13 and 21 h, after the randomization of the participants. With a 7-day interval, participants crossed over to the other group. Results From 126 eligible participants, 8 with hemiparetic post-first-ever ischemic stroke at the subacute phase were recruited (age: 53.2 +/- 16.2; 6 women). Physical activity reduced AHI from 19 to 13 n degrees/h and wake after sleep onset from 76.5 to 60.3 min and increased fluid volume of paretic and non-paretic arms and trunk before sleep compared to inactivity. Conclusion An acute bout of physical activity reduced OSA classification based on AHI (from moderate to mild) and sleep fragmentation. Our results provide preliminary evidence of a possible link between physical activity in patients after stroke as an intervention to counteract OSA severity and improve sleep.
- Corneal and Coronary Calcification in Maintenance Hemodialysis: The Face Is No Index to the Heart(2023) PESSOA, Maria Beatriz C. N.; SANTO, Ruth Miyuki; DEUS, Aline A. de; DUQUE, Eduardo J.; CRISPILHO, Shirley F.; JORGETTI, Vanda; DALBONI, Maria Aparecida; ROCHITTE, Carlos Eduardo; MOYSES, Rosa M. A.; ELIAS, Rosilene M.Although the eyes are the main site of metastatic calcification in patients with chronic kidney disease (CKD), corneal and conjunctival calcification (CCC) is poorly evaluated in this population. Whether CCC correlates with coronary artery calcification remains unknown since studies so far have relied on methods with low sensitivity. Our objective was to test the relationship between CCC and coronary calcification based on tomography. This was a cross-sectional study that included patients on maintenance dialysis. Clinical, demographic, and biochemical data (calcium, phosphorus, parathormone, alkaline phosphatase, and 25(OH)-vitamin D) were recorded. Hyperparathyroidism was defined as parathyroid hormone (PTH) > 300 pg/mL. CCC was evaluated by anterior segment optical coherence tomography (AS-OCT), and coronary calcium scores (Agatston method) were assessed by computed tomography. We compared no/mild with moderate/severe CCC. Twenty-nine patients were included (49.6 +/- 15.0 years, 62.1% female, on hemodialysis for 5.7 [2.7-9.4] years, 17.2% with diabetes mellitus, 75.9% with hyperparathyroidism). CCC was found in 82.7% of patients, with median scores of 9 (3, 14.5), ranging from 0 to 16. CCC was classified as absent/mild, moderate, and severe in 27.6%, 20.7%, and 51.7%, respectively. Coronary calcification was found in 44.8% of patients, with median scores of 11 (0, 464), varying from 0 and 6456. We found no significant correlation between coronary calcium scores and CCC (r = 0.203, p = 0.282). Hyperphosphatemia was more frequent in patients with moderate/severe CCC than in those with absent/mild CCC. We concluded that CCC was frequent in patients with CKD on dialysis and did not correlate with coronary calcium scores. Hyperphosphatemia appears to contribute to CCC.(c) 2023 The Authors.
