A Prospective Study

Abstract Objective The evaluation of physical activity for chronic hemodialysis patients is a new approach for patient global care. The objective of this work is to evaluate the physical activity in chronic hemodialysis patients and identify the risk factors associated with reduced physical activity. This is a prospective study for 6 months including 150 chronic hemodialysis patients in the Guelmim-Oued Noun Regionin Moroccan Sahara. We use Baecke's survey, translated and validated in Arabic local language. The socio-demographic, clinical, and biological data were completed during the interrogation and from the medical records of the patients. Results The mean age of our patients was 54.6 ± 16.4 years, with male predominance (59%). Most patients have a low education level and 60% were illiterate. Hypertension was found in 54% of our patients, diabetes in 39%, and cardiovascular disease in 10% of patients. Low Physical activity was associated with gender (OR = 4.05), age (OR = 1.03) and high education level (OR = 0.2). Our work has met the various pre-established objectives, however other more specific studies must be conducted to better characterize the profile of physical activity in chronic hemodialysis patients.

Abstract Background COVID-19 lockdowns may lead to physical inactivity, a major risk factor for non-communicable diseases. This study aims to determine: 1) the trajectory in daily step counts before, during and after the lockdown in China, and 2) the characteristics associated with the trajectories. Methods From December 2019 to July 2020, smartphone-based step counts were continuously collected in 815 Chinese adults residing in Shanghai over 202 days across three phases: before, during, and after the lockdown. Participant characteristics were reported, and height, weight and body composition measured before the lockdown. A ‘sharp’ regression discontinuity design with cluster robust standard errors was used to test the effect of the lockdown and reopening on daily steps and a linear mixed model was used to examine the characteristics associated with trajectories during the observed period. Results Based on 164,630 person-days of data, we found a sharp decline in daily step counts upon the lockdown (24/01/2020) by an average of 3796 (SE = 88) steps, followed by a significant trend of increase by 34 steps/day (SE = 2.5; p < .001) until the end of the lockdown (22/03/2020). This increasing trend continued into the reopening phase at a slower rate of 5 steps per day (SE = 2.3; p = 0.029). Those who were older, married, university educated, insufficiently active, had an ‘at risk’ body composition, and those in the control group, were slower at recovering step counts during the lockdown, and those who were older, married, without university education and with an ‘at risk’ body composition recovered step counts at a slower pace after the reopening. Conclusions Despite later increases in step counts, COVID-19 lockdown led to a sustained period of reduced physical activity, which may have adverse health implications. Governments and health professionals around the world should continue to encourage and facilitate physical activity during the pandemic.

Women drastically loose bone during and after menopause leading to osteoporosis, a disease characterized by low bone mass increasing the risk of fractures with minor trauma. Existing therapies mainly reduce bone resorption, however, all existing drugs have severe side effects. Recently, the focus is to identify alternative medicines that can prevent and treat osteoporosis with minimal or no side effects. We usedCissus quadrangularis(CQ), a medicinal herb, to determine its effects on bone loss after ovariectomy in C57BL/6 mice. Two-month old mice were either sham operated or ovariectomized and fed CQ diet. After eleven weeks, mice were sacrificed and the long bones scanned using pQCT andμCT. In the distal femoral metaphysis, femoral diaphysis, and proximal tibia, control mice had decreased cancellous and cortical bone, while CQ-fed mice showed no significant differences in the trabecular number, thickness, and connectivity density, between Sham and OVX mice, except for cortical bone mineral content in the proximal tibia. There were no changes in the bone at the tibio-fibular junction between groups. We conclude that CQ effectively inhibited bone loss in the cancellous and cortical bones of femur and proximal tibia in these mice.

Background: Reduced physical activity can cause obesity and metabolic syndrome, leading to fibrosis in cardiac muscles and premature cardiac aging. Physical activity, along with herbal supplements, can have a synergistic effect on preventing cardiac muscle proteolysis. Objectives: In this study, the effects of curcumin and resistance training were assessed on cardiac muscle atrophy in obese rats. Methods: Twenty-four male Sprague rats were categorized into four groups, including the placebo, resistance training, curcumin, and resistance training + curcumin. Resistance training was performed three times a week with three sets in each session, repeated five times for eight weeks. During this time, 150 mg/kg curcumin was administered through gavage. Twenty-four hours after finishing resistance training, surgery was performed on the cardiac muscle, and gene expressions of PGC1-α, FOXO1, Murf-1, Atrogin, Collagen1, and Collagen 3 were assessed with real-time PCR. Results: The expression of PGC1-α and FOXO1 genes in both resistance training and resistance training+curcumin groups significantly increased and decreased, respectively, compared to the control group (P = 0.001). The MuRF1 expression in the curcumin+resistance training group decreased significantly (P = 0.013) compared to the placebo and curcumin groups. The expression of collagen type 1 and type 2 in all the three treatment groups had significant decreases compared to the placebo group (P < 0.05). Conclusions: Considering the results of this study, resistance training and curcumin supplement each alone can prevent cardiac muscle atrophy. However, the simultaneous use of curcumin supplement and resistance training can lead to synergistic effects.
