Purpose: Many evidence-based studies have indicated that cinnamon has therapeutic effects. However, it may not be entirely safe and its adverse effects may be ignored. The present umbrella review was conducted to elucidate the safety of cinnamon.Methods: Pertinent meta-analyses and systematic reviews of randomized controlled trials on cinnamon use in humans were identified by searching PubMed, EMBASE, and the Cochrane Library from their inception to September 15, 2021. All meta-analyses and systematic reviews on the safety or adverse effects of cinnamon were considered. PRISMA 2020 was used as the standard of reporting (PRISMA registration ID: 286746).Results: We identified three meta-analyses and one systematic review that described the safety of cinnamon. The quality of the meta-analysis and systematic reviews was evaluated using “Assessing the Methodological Quality of Systematic Reviews.” Their quality was rated as low in two (50%) instances and moderate in two (50%). There were no significant toxic- or side effects between cinnamon group and placebo group regardless of dose and duration.Conclusion: There is evidence to support that the use of cinnamon has no adverse reactions. It can improve the health status of patients as an adjuvant treatment. Future studies exploring better profile risks and protective factors for cinnamon use-related adverse effect are needed, in order that preventive approaches can be developed.

Aim: The objective of this study was to assess whether an elderly patient’s frailty was associated with acute kidney injury (AKI) and to examine whether severe frailty group had an increased risk of AKI than mild–moderate group. Methods: We searched The Cochrane Library, PubMed, and EMBASE for relevant studies without language limitations before 1 March 2019 with a priori defined inclusion and exclusion criteria. Five population-based cohort studies were included for systematic review and meta-analysis. Results: Compared with the control group, the frailty group is significantly associated AKI (Odds Ratio = 2.05; 95% CI: 1.23–3.43). The moderate-severe frailty group has an increased risk of AKI than mild frailty group (Hazard Ratio = 2.87; 95% CI: 1.60–5.17. Conclusion: In conclusion, the available best evidence support an association between frailty and AKI among elder patients, thus relevant interventions should be taken among elderly under potential risk of AKI.

Background It remains unknown whether child-oriented asthma education is associated with better health outcomes. This meta-analysis investigated the effects of asthma education on hospitalisation and emergency department and clinic visits. Methods We searched the Cochrane Library, PubMed and EMBASE for relevant studies from inception to 4 July 2021, and selected studies that reported hospitalisation or emergency department or clinic visits as outcomes. The participants were only children. Two authors independently selected the studies, assessed the quality of the included studies and retrieved the data. A third senior author was engaged to resolve disagreements. Fifteen longitudinal studies were included for the systematic review and meta-analysis. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 was used as the standard of reporting (PRISMA registration ID is 284509). Findings Compared with the control group, the asthma education group had 54% lower hospitalisation risk (95% CI 0.32 to 0.66), and 31% lower emergency department visit risk (95% CI 0.59 to 0.81). Sensitivity analysis showed that the asthma education group had a reduced clinic visit risk (risk ratio (RR)=0.80, 95% CI 0.67 to 0.97). Subgroup analysis showed that asthma education involving both children and parents/guardians was associated with fewer hospitalisations (RR=0.38, 95% CI 0.24 to 0.59) and emergency department visits (RR=0.69, 95% CI 0.57 to 0.83). Asthma education in hospitals or non-hospitals can reduce the risk of hospitalisation and emergency department visits. However, only education in the hospitals was associated with the reduction of clinical visits (RR=0.45, 95% CI 0.22 to 0.92). Interpretation Education is effective for controlling asthma, especially for reducing hospitalisation and emergency department and clinic visits. Education involving both children and parents/guardians is more effective than that involving only children. The setting of asthma education does not impact its effect to a large extent.

Parental vaccine-hesitancy can lead to delays or refusal to vaccinate children despite the availability of vaccines. This is a population-based, cross-sectional study investigating whether parents in China are hesitant to vaccinate their children with a COVID-19 vaccine booster. Parents in Taizhou, China, responded to a self-reported online questionnaire on their hesitancy to vaccinate their children with a COVID-19 vaccine booster. Of the 1252 parents who were invited to answer the structured questionnaire, 514 (41.1%) samples had valid data for data analysis. A total of 41.8% of participants were hesitant to give their children a COVID-19 vaccine booster. After adjusting for confounders, parental gender (female vs. male parent, OR=0.56 95% CI: 0.32–0.87), parental opinion (yes vs. no, OR=0.17, 95% CI: 0.09–0.30), parental attitudes (yes vs. no, OR=0.28, 95% CI: 0.16–0.50), the presence of people around them who are generally hesitant to receive COVID-19 booster vaccines for children (yes vs. no, OR=0.14, 95%CI: 0.08–0.23), the individual hesitancy of people around them to administer booster COVID-19 vaccines to children (yes vs. no, OR=0.02, 95%CI: 0.02–0.22), and parents’ hesitancy to receive a booster vaccine for their children showed significant correlation. The disparity of factors related to booster vaccine-hesitancy for children between fathers and mothers was also found. We found that a moderate proportion of parents reported that they were hesitant to give their children a COVID-19 vaccine booster. The results suggest that an in-depth, dynamic assessment and further health education planning are necessary to reduce Chinese parents’ hesitancy to vaccinate their children.

Following COVID-19 vaccination, several herpes zoster cases have been reported, making it critical to explore the association between herpes zoster and COVID-19 vaccination. This is especially true...

In recent years, online consumer credit in China has boomed. Many Chinese undergraduates are interested in utilizing online consumer credit to meet their increasing consumption needs. However, the explosion in online loans to students has created many problems. Based on a survey of 286 undergraduate students from four universities in Beijing, the capital of China, this study provides an empirical analysis of the economic and social determinants of undergraduates’ consumer credit. The estimation results indicate that online consumer credit demand is positively related to years of schooling, monthly living expenses, financial support from the student’s university, and consumption preferences. However, other factors, including major field of study, highest level of parental education, and advertisements in the media and on campus, have negative influences on undergraduates’ online consumer credit. The findings have significant practical and policy implications. Specifically, it is necessary and important for the government, universities, and families to coordinate to guide and educate college students to utilize online loans properly and wisely.
