The effect of foot bath on sleep quality in the elderly: a systematic review.

INTRODUCTION: Population aging is a problem that has affected most countries in the world. Poor-quality sleep is a common complaint among the elderly. Foot baths are a method of heat therapy and are performed as an independent nursing care in different departments. The present study was conducted with the aim of investigating the effects of foot baths with spa on improving the sleep quality of the elderly. METHODS: This research is a systematic review. We systematically searched six databases, including Google Scholar, PubMed, Web of Science, Scopus, Embase, and the World Health Organization databases, to retrieve the related articles based on the keywords used in our search strategy from 2010 to March 2023. RESULT: Finally, 10 articles were included in this study. All studies were randomized controlled trial (RCTs) and semi-experimental. In all 9 studies, the positive effects of the foot bath were reported. In 9 studies, the effect of foot baths with water above 40 degrees Celsius was reported. The PSQR questionnaire was used in most of the studies. CONCLUSION: The total findings of this study showed that due to the high prevalence of sleep problems in the elderly, foot baths with warm water can be used as an easy, simple, and safe nursing intervention to improve sleep quality. Therefore, it can be used in nursing homes and hospitals. It is also a non-pharmacological and inexpensive nursing intervention that can be implemented by the elderly themselves after training by community health nurses.

Combined dandelion extract and all-trans retinoic acid induces cytotoxicity in human breast cancer cells.

Breast cancer is one of the most prevalent and deadly cancers among women worldwide. Recently, natural compounds have been widely used for the treatment of breast cancer. Present study evaluated antiproliferative and anti-metastasis activities of two natural compounds of dandelion and all-trans-retinoic acid (ATRA) in human MCF-7 and MDA-MB231 breast cancer cells. We also evaluated the expression of MMP-2, MMP-9, IL-1ß, p53, NM23 and KAI1 genes. Data showed a clear additive cytotoxic effect in concentrations of 40 µM ATRA with 1.5 and 4 mg/ml of dandelion extract in MCF-7 and MDA-MB231 cells, respectively. In both cell lines, compared with the untreated cells, the expression levels of MMP-9 and IL-1ß were significantly decreased while p53 and KAI1 expression levels were increased. Besides, MMP-2 and NM23 had different expressions in the two studied cell lines. In conclusion, dandelion/ATRA co-treatment, in addition to having strong cytotoxic effects, has putative effects on the expression of anti-metastatic genes in both breast cancer cells.

Effects of milk protein concentrate supplementation on metabolic parameters, adipocytokines and body composition in obese women under weight-loss diet: study protocol for a randomised controlled trial.

INTRODUCTION: Obesity impairs metabolic function and increases the risk of cardiovascular disease and type 2 diabetes mellitus. Evidence suggests that high-protein diets help to increase weight loss and protect against weight gain. Milk protein concentrate (MPC) is a dairy product with a high protein content with a ratio of casein and whey protein similar to skim milk. This trial aims to evaluate the effect of MPC supplementation in obese women under a weight-loss diet. METHODS AND ANALYSIS: We will conduct a 2-month open-label, parallel-group, randomised controlled trial to determine the effect of MPC supplementation on levels of glycaemic and lipid profile, leptin, adiponectin, appetite, waist circumference, body mass index and body composition in 44 premenopausal obese women on a weight-loss diet. ETHICS AND DISSEMINATION: This protocol, approved by the Medical Ethics Committee of Ahvaz University of Medical Sciences, is in accordance with the Declaration of Helsinki (approval number: IR.AJUMS.REC.1399.795). The trial results will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: Iranian Registry of Clinical Trials (IRCT20201223049804N1).

Effect of Green Tea on Anthropometric Indices and Body Composition in Patients with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis.

AIM: Previous studies that investigated the effect of green tea/green tea extract on anthropometric indices among type 2 diabetes mellitus (T2DM) patients found inconsistent results. Thus, in order to clarify the efficacy of green tea supplementation on anthropometric indices and body composition, we conducted a systematic review and meta-analysis to sum up the evidence of randomized controlled trials. METHODS: A systematic search was conducted in the Scopus, ISI Web of Science and PubMed to find the related articles, up to June 2019. Meta-analysis was performed using the random effects model, and the I2 index was used to evaluate the heterogeneity. RESULTS: Eleven articles were eligible. Our meta-analysis indicated that green tea consumption significantly decreased body weight, body mass index (BMI), and body fat (BF). The beneficial effect of green tea intake was observed in long-term intervention (>8 weeks), at lower doses of green tea (dosage ≤800 mg/day), and in overweight patients. CONCLUSION: This study revealed the beneficial effects of green tea consumption in reducing body weight, BMI, and BF in T2DM patients. It should be noted that green tea was effective in long-term intervention, at lower doses of green tea, and in overweight patients.

Effects of Concurrent Omega-3 and Cranberry Juice Consumption Along with Standard Antibiotic Therapy on the Eradication of Helicobacter pylori, Gastrointestinal Symptoms, Some Serum Inflammatory and Oxidative Stress Markers in Adults with Helicobacter pylori Infection: A Study Protocol for a Randomized Controlled Trial.

BACKGROUND: It seems alternative treatments such as antioxidant intervention and anti-inflammatory intervention adjuvant to antibiotic regimens may enhance cancer prevention approaches and decrease adverse side effects related to therapeutic antibiotic regimens. So, we will evaluate the effects of concurrent omega-3 and cranberry juice supplementation along with standard antibiotic therapy on the eradication of Helicobacter pylori, gastrointestinal symptoms, some serum inflammatory and oxidative stress markers in adults with HP infection. METHODS: We will conduct a 4-week double-blinded randomized clinical trial. The subjects will be randomly stratified according to sex and BMI using a permuted block randomization procedure by Random Allocation Software (RAS). They will be assigned to one of the four study groups: (1) cranberry juice fortified with omega-3 Intervention (n=23), (2) cranberry juice intervention group (n=23), (3) placebo beverage fortified with omega-3 intervention group (n=23), and (4) placebo beverage intervention (control group) (n=23). All statistical analyses will be performed using IBM SPSS Statistics software. DISCUSSION: A combination of alternative therapies may have a synergistic effect compared to a single approach. It could potentially be more effective in promoting the efficacy of standard antibiotic therapy in eradicating HP infection.

Whey protein supplementation reducing fasting levels of anandamide and 2-AG without weight loss in pre-menopausal women with obesity on a weight-loss diet.

BACKGROUND: Despite the importance of dairy proteins in modifying of metabolic abnormalities, no attention has been given to their effects on endocannabinoids. METHODS: A total number of 60 obese women were recruited in a 2-month randomized clinical trial. Following random allocation, they were assigned to one of the two groups: control (n = 30) and intervention (n = 30). Then, all the subjects followed a hypocaloric diet of 800 kcal below estimated energy needs. The intervention group received isocaloric weight-loss diet and whey protein powders (30 g/day). Baseline and 2-month fasting anthropometric, blood glucose, serum insulin, insulin resistance, lipid profile, AEA, and 2-AG were measured. RESULTS: The study groups were homogenous in terms of baseline characteristics (p > 0.05) except for MUFA intake (p = 0.021). There were no significant differences in energy and macronutrient intakes in the intervention group compared to the control group at the end of the study (p > 0.05). The results of the ANCOVA did not show significant reductions in body weight and BMI of the intervention group compared to the control group (p > 0.05); however, WC, body fat, FBS, AEA, 2-AG, total cholesterol, and triglyceride decreased and HDL-c significantly increased in the intervention group compared to the control group (p < 0.05). CONCLUSIONS: In this study, the effects of simultaneous weight-loss diet and whey protein supplementation on the reduction of endocannabinoids were determined.

Effectiveness of mindfulness based cognitive therapy on weight loss, improvement of hypertension and attentional bias to eating cues in overweight people.

OBJECTIVES: Prevalence rates of overweight and obesity are dramatically ever-increasing across the world. Therefore, this study was to evaluate the effect of mindfulness-based cognitive therapy (MBCT) on weight loss, hypertension, and attentional bias towards food cues in a group of women affected with this condition. METHODS: A total of 45 participants were selected out of women referring to the Nutrition and Diet Therapy Clinic affiliated to Shahid Beheshti University of Medical Sciences, Iran, and then randomized into three groups of 15. The first experimental group was subjected to an energy-restricted diet therapy together with MBCT during 8 sessions, the second group took the diet therapy alone, and the third group received no intervention. Body mass index (BMI), hypertension, and attentional bias towards food cues were correspondingly evaluated before, at the end, and four weeks after the completion of the interventions. RESULTS: The results of this study revealed that MBCT, along with diet therapy, had been significantly more effective in weight loss, decrease in BMI, lower systolic blood pressure (SBP), and attentional bias towards food cues compared with the diet therapy alone (P ≤ 0.01). MBCT had no significant impact on the decline in diastolic blood pressure (DBP) in participants in the follow-up phase. CONCLUSION: This study demonstrated that MBCT along with the conventional diet therapy was more effective in weight loss, decrease in BMI, hypertension control, as well as attentional bias towards food cues than the diet therapy alone.

The effect of green tea on C-reactive protein and biomarkers of oxidative stress in patients with type 2 diabetes mellitus: A systematic review and meta-analysis.

INTRODUCTION: The beneficial effects of green tea on regulating insulin sensitivity and preventing the development of type 2 diabetes mellitus (T2DM) have been identified. OBJECTIVES: We aimed to investigate the effect of green tea on serum levels of C-reactive protein (CRP) and biomarkers of oxidative stress in patients with T2DM. METHODS: A systematic search was performed in the ISI Web of science, PubMed and Scopus to find articles related to the effect of the green tea on CRP, malondealdehyde (MDA) and total antioxidant capacity (TAC) in T2DM patients, up to June 2019. There was no language and time limitation. Meta-analyses were performed using both the random and fixed effects model where appropriate, and I2 index was used to evaluate the heterogeneity. RESULTS: Initial search yielded 780 publications. Eight articles with 614 T2DM patients were eligible. Following green tea consumption, CRP levels significantly decreased (weighted mean difference (WMD): -5.51 mg/dl, 95% CI: -9.18 to -1.83, p = 0.003) compared with the controlled group. Green tea consumption had no significant effect on plasma levels of TAC and MDA (0.02 mg/dl, CI: -0.06 to 0.10; -0.14 mg/dl, CI: -0.40 to 0.12; respectively). CONCLUSION: This systematic review and meta-analysis indicated that green tea significantly reduced the circulating levels of CRP, whereas, it had no significant effect on MDA and TAC. Overall, green tea can be considered as a healthy drink to reduce CRP levels in T2DM patients.
