Meta AnalysisErtapenem versus ceftriaxone for the treatment of complicated infections: a meta-analysis of randomized controlled trials.
Ertapenem has been demonstrated to be highly effective for the treatment of complicated infections. The aim of this study was to compare the efficacy and safety of ertapenem with ceftriaxone. ⋯ Ertapenem can be used as effectively and safely as ceftriaxone for the treatment of complicated infections. It is an appealing option for the treatment of these complicated infections.

Comparative study of mutation spectrums of MT-RNR1 m.1555A>G, GJB2, and SLC26A4 between familial and sporadic patients with nonsyndromic sensorineural hearing loss in Chinese Han.
The mutation frequencies of three common deafness genes (MT-RNR1 m.1555A>G, GJB2, and SLC26A4) among patients with nonsyndromic sensorineural hearing loss (NSHL) were different in previous studies. Inconsistent selection criteria for recruiting patients could have led to differences in estimating the frequencies of genetic mutations thus resulting in different mutation frequencies among these studies. The aim of this study was to reveal the differences in the mutation spectrums of the three common genes between familial and sporadic Chinese Han patients. ⋯ It is necessary to reveal the differences in gene mutation frequencies between patients of different sources or characteristics by comparative studies in order to avoid selection bias. The mutations of GJB2, SLC26A4, and MT-RNR1 m.1555A>G are the most important etiological factors in Chinese Han patients, among which SLC26A4 might be the most frequent.

High expression of follicle stimulating hormone receptor in testicular tissue of idiopathic azoospermic patients with severe spermatogenic defects.
Follicle stimulating hormone is necessary for normal reproduction in men. The biochemical actions of follicle stimulating hormone result from binding to the follicle stimulating hormone receptor in the plasma membrane of Sertoli cells. Here, we investigated the expression of the follicle stimulating hormone receptor in different testicular histological phenotypes of patients with idiopathic azoospermia. ⋯ Different serum follicle stimulating hormone levels and follicle stimulating hormone receptor expression were found in the different testicular histology phenotypes in azoospermic patients. Differential follicle stimulating hormone receptor expression in testicular tissue of patients with idiopathic azoospermia may be associated with the degree of spermatogenesis.

Review Meta AnalysisPerformance of K-ras mutation analysis plus endoscopic ultrasound-guided fine-needle aspiration for differentiating diagnosis of pancreatic solid mass: a meta-analysis.
Difficulties persist in differentiating pancreatic ductal adenocarcinomas (PDAC) from pancreatic inflammatory masses (PIM). Auxiliary diagnostic techniques which enhance the endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) diagnostic yield have been attempted, for example, K-ras mutation analysis. We aimed to evaluate the accuracy of K-ras mutation analysis combined with EUS-FNA for the differential diagnosis of PDAC and PIM by pooling data of existing trials. ⋯ Combining K-ras mutation analysis with routine cytology moderately improves the ability of EUS-FNA to differentially diagnose between PDAC and PIM, especially for patients with suspected PDAC yet inconclusive EUS-FNA findings, and may prove to be a valuable supplemental method to EUS-FNA.
