METHODS: The literature search was implemented in four following databases: Web of Science, Scopus, PubMed/Medline, and Google Scholar, thus, determining studies that measured the effects of walnut consumption on adiponectin, leptin, and glycemic biomarkers levels from 2004 up to December 2019.
RESULTS: Fourteen trials were include in the meta-analysis, with an intervention period ranging from 5 weeks to 12 months.Walnut intake increased leptin (weighted mean difference (WMD): 2.502 ng/mL; 95 % CI: 2.147-2.856, p
DESIGN: Randomised trial.
SETTING: University Hospital, Malaysia: April 2016-April 2017.
POPULATION: One hundred and sixty women hospitalised for HG.
METHOD: Women were randomised upon admission to fasting for 12 hours or expedited oral feeding. Standard HG care was instituted.
MAIN OUTCOME MEASURE: Primary outcome was satisfaction score with overall treatment at 24 hours (0-10 Visual Numerical Rating Scale VNRS), vomiting episodes within 24 hours and nausea VNRS score at enrolment, and at 8, 16 and 24 hours.
RESULTS: Satisfaction score, median (interquartile range) 8 (5-9) versus 8 (7-9) (P = 0.08) and 24-hour vomiting episodes were 1 (0-4) versus 1 (0-5) (P = 0.24) for 12-hour fasting versus expedited feeding, respectively. Repeated measures analysis of variance of nausea scores over 24 hours showed no difference (P = 0.11) between trial arms. Participants randomised to 12-hour fasting compared with expedited feeding were less likely to prefer their feeding regimen in future hospitalisation (41% versus 65%, P = 0.001), to recommend to a friend (65% versus 84%, P = 0.01; RR 0.8, 95% CI 0.6-0.9) and to adhere to protocol (85% versus 95%, P = 0.04; RR 0.9, 95% CI 0.8-1.0). Symptoms profile, ketonuria status at 24 hours and length of hospital stay were not different.
CONCLUSION: Advisory of 12-hour fasting compared with immediate oral feeding resulted in a non-significant difference in satisfaction score but adherence to protocol and fidelity to and recommendation of immediate oral feeding to a friend were lower. The 24-hour nausea scores and vomiting episodes were similar.
TWEETABLE ABSTRACT: Women hospitalised for hyperemesis gravidarum could feed as soon, as much and as often as can be tolerated compared with initial fasting.
DESIGN, PATIENTS AND MEASUREMENTS: Patients with AI on twice-daily hydrocortisone, who had low or moderate risk and intended to fast, were recruited. Patients were converted to prednisolone 5 mg once daily taken at sahur (predawn) and Ramadan education given. Weight, sleep duration, biochemical parameters and quality of life measures (SF-36 questionnaire) were analysed at the end of Ramadan and compared against baseline.
RESULTS: Twenty patients (13 men) were recruited, with a mean age of 59.9 ± 15.0 years. All patients were on hydrocortisone 15 mg daily (in divided doses) as pre-Ramadan glucocorticoid replacement. Half had type 2 diabetes with low IDF-DAR risk. Eighty-five percent of patients completed the full 29 days of fasting with no complications. There was a significant reduction in weight (-1.1 ± 1.6 kg, p = .005), with no significant change in blood pressure or sleep duration. There was a significant increase in urea (0.80 ± 1.1 mmol/L, p = .005) and haematocrit, (0.011 ± 0.019 L/L, p = .019) and decrease in serum sodium (-1.6 ± 3.0 mmol/L, p = .028), with no change in serum creatinine or liver function. Quality of life measures were preserved in all domains with significant improvement in role limitation due to physical health (15.3 ± 21.6, p = .005) and bodily pain (8.8 ± 16.3, p = .031).
CONCLUSIONS: This study has demonstrated that converting patients with AI who are fasting for Ramadan from twice-daily hydrocortisone to prednisolone 5 mg daily at sahur was safe, with no major short-term adverse effects. Despite the higher equivalent glucocorticoid doses, patients experienced weight loss and no clinically significant change in blood pressure, sleep, biochemical parameters or quality of life. This study paves the way to trial even lower doses of prednisolone once daily in patients fasting for Ramadan with AI.
METHODS: A comprehensive systematic search was performed in Web of Science, PubMed/MEDLINE, Cochrane, SCOPUS and Embase from inception until June 2019. All clinical trials investigating the effects of fasting and energy-restricted diets on leptin and adiponectin in adults were included.
RESULTS: Twelve studies containing 17 arms and a total of 495 individuals (intervention = 249, control = 246) reported changes in serum leptin concentrations, and 10 studies containing 12 arms with a total of 438 individuals (intervention = 222, control = 216) reported changes in serum adiponectin concentrations. The combined effect sizes suggested a significant effect of fasting and energy-restricted diets on leptin concentrations (WMD: -3.690 ng/ml, 95% CI: -5.190, -2.190, p ≤ 0.001; I2 = 84.9%). However, no significant effect of fasting and energy-restricted diets on adiponectin concentrations was found (WMD: -159.520 ng/ml, 95% CI: -689.491, 370.451, p = 0.555; I2 = 74.2%). Stratified analyses showed that energy-restricted regimens significantly increased adiponectin (WMD: 554.129 ng/ml, 95% CI: 150.295, 957.964; I2 = 0.0%). In addition, subsequent subgroup analyses revealed that energy restriction, to ≤50% normal required daily energy intake, resulted in significantly reduced concentrations of leptin (WMD: -4.199 ng/ml, 95% CI: -7.279, -1.118; I2 = 83.9%) and significantly increased concentrations of adiponectin (WMD: 524.04 ng/ml, 95% CI: 115.618, 932.469: I2 = 0.0%).
CONCLUSION: Fasting and energy-restricted diets elicit significant reductions in serum leptin concentrations. Increases in adiponectin may also be observed when energy intake is ≤50% of normal requirements, although limited data preclude definitive conclusions on this point.
RESULTS: We found that cumulative food intake was not changed in the group with 12 h daily fasting, but significantly decreased in the 16 and 20 h fasting groups. The composition of gut microbiota was altered by all these types of intermittent fasting. At genus level, 16 h fasting led to increased level of Akkermansia and decreased level of Alistipes, but these effects disappeared after the cessation of fasting. No taxonomic differences were identified in the other two groups.
CONCLUSIONS: These data indicated that intermittent fasting shapes gut microbiota in healthy mice, and the length of daily fasting interval may influence the outcome of intermittent fasting.
