There is no strong evidence of a protective effect of exclusive breastfeeding for at least 3 months against AD, even among children with a positive family history.

A large number of epidemiological studies have provided conflicting results about the relationship between tea consumption and ovarian cancer. This study aimed to clarify the association between tea consumption and ovarian cancer. A literature search of the MEDICINE, Scopus, PubMed, and Web of Science databases was performed in April 2016. A total of 18 (11 case-control and 7 cohort) studies, representing data for 701,857 female subjects including 8,683 ovarian cancer cases, were included in the meta-analysis. A random-effects meta-analysis was used to compute the pooled relative risks (RR), meta regression, and publication bias, and heterogeneity analyses were performed for the included trials. We found that tea consumption had a significant protective effect against ovarian cancer (relative risk [RR] = 0.86; 95% confidence interval [CI]: 0.76, 0.96). The relationship was confirmed particularly after adjusting for family history of cancer (RR = 0.85; 95% CI: 0.72, 0.97), menopause status (RR = 0.85; 95% CI: 0.72, 0.98), education (RR = 0.82; 95% CI: 0.68, 0.96), BMI (RR = 0.85; 95% CI: 0.70, 1.00), smoking (RR = 0.83; 95% CI: 0.72, 0.93) and Jadad score of 3 (RR = 0.76; 95% CI: 0.56, 0.95) and 5 (RR = 0.74; 95% CI: 0.59, 0.89). The Begg's and Egger's tests (all P > 0.01) showed no evidence of publication bias. In conclusion, our meta-analysis showed an inverse association between tea consumption and ovarian cancer risk. High quality cohort-clinical trials should be conducted on different tea types and their relationship with ovarian cancer.

Hong M, Lu CJ. Efficacy observation on acupuncture-moxibustion for urinary retention after surgery for cervical cancer. AbstractObjective: To observe the efficacy of acupuncture-moxibustion therapy in treating urinary retention after surgery for cervical cancer. Methods: Fifty eligible patients were randomized into a treatment group and a control group by their visiting sequence, 25 in each group. The control group was intervened by indwelling urethral catheter after gynecological surgery; while the treatment group started to receive acupuncture-moxibustion and cupping treatment at the 7th day after surgery, in addition to the intervention given to the control group. The residual urine volume and total effective rate of the two groups were detected. Results: After 7-day treatments, the total effective rate was 92.0% in the treatment group versus 72.0% in the control group, and the difference was statistically significant (P＜0.05). Conclusion: Acupuncture-moxibustion treatment plus cupping based on the conventional intervention is effective for urinary retention after surgery for cervical cancer, worth promoting in clinic.

Objectives This study evaluated the Human T‐lymphotropic virus (HTLV) screening policy impact on the HTLV seroprevalence from 2009 to 2018 as well as the differences between administrative districts in terms of prevalence distribution in Taiwan. Background Since February 1996, the Taiwan Blood Services Foundation (TBSF) had conducted HTLV screening of blood donors. The HTLV seroprevalence was 0.032% in 1999. Materials and Methods This cross‐sectional study included donors' data collected from blood donation centres across Taiwan from 2009 to 2018. Enzyme immunoassay and Western blot assay were used for screening and confirmation of HTLV infections. In this study, the researchers calculated the trends in the HTLV rates of first‐time and repeat donors across time as well as the HTLV prevalence distribution across the 22 administrative districts of Taiwan. Results Amongst 17 977 429 employed blood donations, 739 HTLV‐seropositive donations (4.11 per 100 000 donations) were identified. The HTLV‐positive donors were aged between 17 and 64 years, with a median age of 49 years. The overall seropositivity rates of first‐time and repeat donors were 34.36/100 000 and 1.27/100 000. HTLV seroprevalence in first‐time blood donors significantly decreased by 57% (crude odds ratio [95% confidence interval] (crude OR [95% CI]) = 0.43 [0.28–0.64]) within 10 years. A slight decline was also identified in repeat donors (crude OR [95% CI] = 0.73 [0.4–1.32]). Donors from different districts showed significantly varied prevalence. Most districts with high prevalence are situated in eastern Taiwan, for both donation types. Older blood donors were more likely to be infected with HTLV than younger ones in first time and repeat donors. Middle age donors (50–65 years) had an 18.47–39.65 greater risk than those aged <20 years. Significant higher risk of female was observed in both donation types. Amongst different age groups, first‐time female donors increase 1.31–1.88 times infection risk and female in repeat donor group had 1.55–3.43 times greater risk. Conclusion Over years of implementation of the HTLV blood donor screening policy by the TBSF, the HTLV seroprevalence of first‐time donors has decreased consistently. Moreover, the HTLV seroprevalence of repeat donors has dropped considerably. This implies that the screening policy provides continued benefit. Females and older blood donors were more likely infected with HTLV than males and younger blood donors. The influence of age on infection was greater amongst first‐time donors than amongst repeat donors. Therefore, appropriate measures should be taken to ensure public safety.
