Acupuncture for common cold: A systematic review and meta-analyze protocol

Prevalence of Antibiotic Resistance Genes in Air-Conditioning Systems in Hospitals, Farms, and Residences

High-throughput quantitative PCR combined with Illumina sequencing and network analysis were used to characterize the antibiotic resistance gene (ARG) profiles in air-conditioning filters from different environments. In total, 177 ARGs comprising 10 ARG types were determined. The detectable numbers and the relative abundance of ARGs in hospitals and farms were significantly higher than those in city and village residences. Compared to hospitals, farms had a higher level of tetracycline, multidrug, integrase, and macrolide⁻lincosamide⁻streptogramin (MLS) B resistance genes but a lower level of beta-lactam resistance genes. The bl3_cpha gene was the most abundant resistance gene subtype in hospital samples with an abundance of 2.01 × 10^-4 copies/16S rRNA, while a level of only 5.08 × 10^-12 copies/16S rRNA was observed in farm samples. There was no significant difference in bacterial diversity among the hospitals, farms, and residences, and Proteobacteria was the most abundant phylum. Network analysis revealed that Proteobacteria and Actinobacteria were possible hosts of the beta-lactam, MLSB, aminoglycoside, multidrug, sulfonamide, and tetracycline resistance genes. The results demonstrate that ARGs exist in indoor environments and that farms and hospitals are important sources. This study provides a useful reference for understanding the distribution patterns and risk management of ARGs in indoor environments.

Soshiho-tang for treating common cold in children younger than 12 years: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Soshiho-tang (SST) is widely used to treat common cold in East Asian countries. Many clinical trials assessing the efficacy and safety of SST formulas for the treatment of pediatric common cold have been reported. The aim of this systematic review is to assess the available clinical evidence on the use of SST formulas in the treatment for common cold in children younger than 12 years.

METHODS

Fifteen databases will be searched from their inception until March 2019. We will be including the randomized controlled trials (RCTs) assessing all types of SST formulas used in the treatment of common cold in children younger than 12 years. The methodological qualities of the RCTs will be assessed using the Cochrane Collaboration tool for assessing the risk of bias, while confidence in the cumulative evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation instrument.

ETHICS AND DISSEMINATION

This systematic review will be published in a peer-reviewed journal and will also be disseminated electronically and in print. The review will be updated to inform and guide health care practices.
