We aimed to make a meta-analysis regarding the effect of bariatric surgery on thyroid function in obese patients. PubMed, EMBASE, CENTRAL, and four Chinese databases were searched for clinical studies. Data were pooled using Review Manager 5.3, and subgroup and sensitivity analyses were performed if necessary and feasible. As a result, 24 articles were included into meta-analysis. Bariatric surgery was associated with significant decrease in TSH, FT3, and T3 levels. However, FT4, T4, and rT3 levels were not significantly changed postoperatively. In addition, bariatric surgery had a favorable effect on overt and subclinical hypothyroid, with reduction of thyroid hormone requirements postoperatively. In conclusion, TSH, FT3, and T3 decrease are expected following bariatric surgery, as well as non-significant change of T4, FT4, and rT3 levels.
Nutritional deficiencies are common in Chinese bariatric surgery candidates. Similar deficiencies were also seen after RYGB and SG. Routine evaluation and related corrections of preoperative nutritional abnormity could contribute to postoperative nutrient balance.
The aim of this study was to screen strongly-antioxidant fruits and vegetables and supply practical diet guidance for the public. We used 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric-reducing antioxidant potential (FRAP), 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) and total reducing power (TRP) assays to investigate antioxidant activities in 110 fruits and vegetables. To analyze the correlation between antioxidant capacities and main reducing substance contents, total phenolic, flavonoid and vitamin C contents were assessed. The results showed great variation in antioxidant activity, and fifteen fruits and vegetables possessed the strongest antioxidant capacities: Toona sinensis, hawthorn, jujube, lotus root, persimmon, red plum, black plum, chilli pepper, star fruit, strawberry, blueberry, cherry, peach, pomegranate and great burdock. Total phenolic contents showed higher correlation with antioxidant capacity when using FRAP and TRP assays than when using the DPPH or ABTS assay. Phenolics and flavonoids, rather than vitamin C, contributed to antioxidant potential in most fruits and vegetables.
The mortality caused by cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) ranks second among female malignant tumour deaths, but their diagnostic and therapeutic targets are still limited. N6‐methyladenosine (m6A) is the most common and extensive modification in mRNA molecules, and its methylation regulators participate in regulating the occurrence and development of many tumours. However, whether m6A RNA methylation regulators can be used as independent prognostic indicators of CESC remains unknown. This study unveiled differential expression of 20 m6A RNA methylation regulators between normal and CESC tumour samples, which RNA sequence data and clinical information were obtained from TCGA database. As a result, five m6A RNA methylation regulators (FTO, HNRNPA2B1, RBM15, IGF2BP1, IGF2BP3) were identified to be significantly linked to CESC tumour status. After Lasso cox regression analysis, six m6A RNA methylation regulators (YTHDC2, YTHDC1, ALKBH5, ZC3H13, RBMX, YTHDF1) were chosen to construct a risk signature. CESC patients were then classified as high‐risk and low‐risk group based on the median risk score. The overall survival (OS) of the CESC patients in high‐risk group was significantly lower than that in low‐risk group, and the area under curve (AUC) is 0.718. Moreover, the risk model can be an independent prognosis factors for CESC patients and can predict OS of CESC patients with different clinical factors. In conclusion, m6A RNA methylation regulators are closely correlated with CESC clinical characteristics and the selected six m6A RNA methylation regulators may be useful for CESC patients personalized treatment.
Background: Scarce data exists about the effect of peer support on individuals with overweight or obesity. This study aimed to conduct a meta-analysis regarding the effect of peer support on weight, BMI, waist circumference, blood pressure, quality of life, social support and depressive symptoms in individuals with overweight and obesity.
Methods: PubMed, Embase, and CENTRAL were searched for relevant studies from their inceptions to 1 Mar 2020, and 14 randomized controlled trials (RCTS) were included. Data were pooled with Review Manager 5.3.
Results: Significantly small improvement in weight (-0.78 kg) was found in individuals who received peer support than those who received usual care (MD= -0.78 kg, 95% CI-1.33 to -0.22, P=0.02). And peer support appeared to be associated with significant decrease in BMI levels (MD= -0.16 kg/m2, 95% CI -0.32 to -0.01, P=0.04). However, there was no statistically significant improvement in the levels of waist circumference, systolic blood pressure, diastolic blood pressure, quality of life, social support and depressive symptoms after peer support.
Conclusion: Peer support appears to be associated with decreased weight and BMI levels in individuals with overweight and obesity. However, additional research is warranted due to insufficient evidence for the effects of peer support on the other health indicators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
