PurposeTwitter is an increasingly popular social media platform within the health care community. The objective of this analysis is to characterize the profile of radiation oncology–related tweets and Twitter users over the past 6 years.Methods and MaterialsUsing the web-based social media analytics platform Symplur Signals, we filtered tweets containing at least 1 of the following hashtags or key words: #radonc, #radiationoncology, "rad onc," or "radiation oncology." We evaluated radiation oncology–related Twitter activity between October 2014 and March 2020 for tweet frequency, tweet content, and individuals or groups posting tweets. We identified the most influential Twitter users contributing to radiation oncology–related tweets.ResultsFrom 2014 to 2020, the quarterly volume of radiation oncology–related tweets increased from 5027 to 29,763. Physicians contributed the largest growth in tweet volume. Academic radiation oncologists comprise 60% of the most influential Twitter accounts responsible for radiation oncology–related content. The number of radiation-oncology resident physicians on Twitter increased from 25 to 328 over the past 6 years, and 20% of radiation-oncology residency programs have a Twitter account. Seventy-one percent of radiation oncology–related tweets generated direct communication via mentions, and 59% of tweets contain links to external sources, including scientific articles.ConclusionsThe number of physicians contributing radiation oncology–related Twitter content has increased significantly in recent years. Academic radiation oncologists are the primary influencers of radiation oncology–related Twitter activity. Twitter is used by radiation oncologists to both professionally network and discuss findings related to the field. There remains the opportunity for radiation oncologists to broaden their audience on Twitter to encompass a more diverse community, including patients. 相似文献
The interlimb coupling, coordination between the limbs, gets hampered in post-stroke hemiparesis. Most of the poststroke motor regimes primarily focus on the more affected limb. 相似文献
Objective: There is a promising perspective regarding the potential effect of resveratrol in preventing and treating metabolic disturbances similar to that of calorie restriction. The aim of this study was to evaluate the effects of calorie-restricted (CR) diet on metabolic parameters and then to investigate whether resveratrol supplementation has beneficial effects similar to CR diet in patients with nonalcoholic fatty liver disease (NAFLD).
Methods: This randomized controlled clinical trial was conducted in 90 patients with NAFLD (males and females) aged 20 to 60 years with body mass index (BMI) ranging from 25 to 35 kg/m2. Participants were assigned to one of three intervention groups as follows: The CR diet group (n = 30) received a prescribed low-calorie diet, the resveratrol group (n = 30) received 600 mg pure trans-resveratrol (2 × 300 mg) daily, and the placebo group (n = 30) received placebo capsules (2 × 300 mg) daily for 12 weeks. Fasting blood samples, anthropometric measurements, and dietary intake and physical activity data were collected for all participants at baseline and at the end of the trial.
Results: CR diet significantly reduced weight (by 4.5%); BMI; waist circumference; waist-to-hip ratio; and serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lipid profiles in participants compared to resveratrol and placebo (all p < 0.05). Significant reductions in weight (by 1.1%) and BMI were found in the resveratrol group compared to the placebo group (p < 0.05). ALT, AST, and lipid profiles did not change significantly in the resveratrol group (all p > 0.05). No significant changes were seen in hepatic steatosis grade, serum glycemic parameters, and high-density lipoprotein cholesterol and sirtuin-1 levels in any group (all p > 0.05).
Conclusions: CR diet with moderate weight loss has favorable effects on NAFLD, and resveratrol supplementation induced weight loss but failed to mimic other aspects of CR diet. Future studies are warranted to evaluate the long-term and dose-dependent effects of resveratrol on metabolic diseases. 相似文献
We aimed to investigate the association of dietary total antioxidant capacity (TAC) with incidence of CKD in subjects with dysglycemia.
Methods
We followed-up 1179 subjects aged ≥30 years with dysglycemia from the Tehran Lipid and Glucose Study (TLGS) for 3 years, who were initially free of CKD. Dietary intakes of TAC, vitamin C, vitamin E, and β-carotene were assessed by a food-frequency questionnaire at the baseline. Dietary TAC was estimated using the oxygen radical absorbance capacity method. Estimated glomerular filtration rate (eGFR) was calculated, using the Modification of Diet in Renal Disease Study equation and CKD was defined as eGFR <60 mL/min/1.73 m2. Odds ratios (ORs) using multivariable logistic regression were reported for the association of incident CKD with dietary TAC.
Results
A total of 197 (16.7%) cases of incident CKD were recorded after 3 years of follow-up. After adjustment for age, sex, smoking, physical activity, body mass index, hypertension, and total energy intake, the top tertile of dietary TAC compared to the bottom was associated with 39% [95% confidence interval (CI) = 0.40–0.93] lower risk of incident CKD (P for trend = 0.025). Furthermore, the highest tertile of vitamin C intake compared to the lowest risk of incident CKD was decreased (OR 0.60; 95% CI 0.38–0.93, P trend 0.023). Intakes of vitamin E and β-carotene were not significantly associated with incident CKD risk.
Conclusion
Our findings suggest that diets high in TAC are associated with a lower risk of incident CKD among subjects with hyperglycemia after 3 years of follow-up.
