The effects of abdominal "I LOV U" massage along with lifestyle training on constipation and distension in the elderly with stroke.

INTRODUCTION: Constipation and distension are dominant gastrointestinal problems after stroke in the elderly. Always they are treated by the use of laxatives and fibers. Abdominal massage along with a healthy lifestyle can be a solution. PURPOSE: This study aimed to investigate the effect of abdominal massage and lifestyle training on constipation and distention of the elderly with stroke. METHOD: This study was a randomized clinical trial that was conducted on elderly patients with stroke at Qaem hospital of Mashhad, Iran. 68 patients were randomly allocated into control (n = 34) and intervention (n = 34) groups in 2017-2018. Finally 29 elderly in the intervention and 34 in the control group completed the study. Intervention included the abdominal massage by using "I LOV U" method along with lifestyle education. Each abdominal massage lasted for 15 min, twice daily for ten days that was performed at first session by the researcher and then continued by the key care giver. Data were collected by the demographic form, constipation assessment score (CAS), distension measurement tool (meter), and food tolerance evaluation checklist. RESULTS: The results indicated that both groups were homogeneous in demographic variables (P > 0.05). The repeated ANOVA showed a more significant decrease in abdominal circumference of the intervention group during the 10- days study (P = 0.029).The Friedman test showed a significant difference in frequency of defecation in two groups in 10- day study (P < 0.0001). Therefore the CAS Score was significantly decreased in intervention group more than the control group (0.30 < 0.98 < 1.59, P = 0.001, EF = 0.44). The food tolerance frequencies through Gavage (P = 0.20), and also orally (P < 0.001) were significantly improved in the intervention group. CONCLUSION: According to results, the abdominal massage along with lifestyle training could improve constipation and distension and also increase food intake tolerance in the elderly patients with stroke.

Sensitivity of PS/CoPd Janus particles to an external magnetic field.

The dual nature of Janus particles confers fascinating properties such as a response to multiple stimuli. In this communication, we systematically study the sensitivity to a uniform external magnetic field of isolated Janus rod-shaped and spherical particles in water confined to two dimensions. The Janus asymmetry of the particles is given by magnetic [Co(0.28 nm)/Pd(0.90 nm)]8 multilayer films deposited onto monodisperse polystyrene (PS) nanorods and microspheres, respectively. It is shown that the particles dispersed in water respond to weak magnetic field applied in in-plane direction. Here we demonstrate that a precise control of the in-plane particle orientation can be obtained for magnetic field strengths higher than 0.1 mT for microspheres and 0.4 mT for nanorods.
