RESUMEN
BACKGROUND: Postoperative complications have a great impact on the postoperative course and oncological outcomes following major cancer surgery. Among them, infective complications play an important role. The aim of this study was to evaluate whether postoperative infective complications influence long-term survival after liver resection for hepatocellular carcinoma (HCC). METHODS: Patients who underwent resection with curative intent for HCC between July 2003 and June 2016 were identified from a multicentre database (8 institutions) and analysed retrospectively. Independent risk factors for postoperative infective complications were identified. After excluding patients who died 90 days or less after surgery, overall survival (OS) and recurrence-free survival (RFS) were compared between patients with and without postoperative infective complications within 30 days after resection. RESULTS: Among 2442 patients identified, 332 (13·6 per cent) had postoperative infective complications. Age over 60 years, diabetes mellitus, obesity, cirrhosis, intraoperative blood transfusion, duration of surgery exceeding 180 min and major hepatectomy were identified as independent risk factors for postoperative infective complications. Univariable analysis revealed that median OS and RFS were poorer among patients with postoperative infective complications than among patients without (54·3 versus 86·8 months, and 22·6 versus 43·2 months, respectively; both P < 0·001). After adjustment for other prognostic factors, multivariable Cox regression analyses identified postoperative infective complications as independently associated with decreased OS (hazard ratio (HR) 1·20, 95 per cent c.i. 1·02 to 1·41; P = 0·027) and RFS (HR 1·19, 1·03 to 1·37; P = 0·021). CONCLUSION: Postoperative infective complications decreased long-term OS and RFS in patients treated with liver resection for HCC.

BACKGROUND: Whether preoperative bodyweight is associated with long-term prognosis in patients after liver resection for hepatocellular carcinoma (HCC) is controversial. This study aimed to investigate the relationship of patient weight with long-term recurrence and overall survival (OS) after curative liver resection for HCC. METHODS: Data for patients with HCC who underwent curative liver resection between 2000 and 2015 in five centres in China were analysed retrospectively in three groups according to their preoperative BMI: underweight (BMI 18·4 kg/m2 or less), normal weight (BMI 18·5-24·9 kg/m2 ) and overweight (BMI 25·0 kg/m2 or above). Patients' baseline characteristics, operative variables and long-term survival outcomes were compared. Univariable and multivariable Cox regression analyses were performed to identify risk factors for OS and recurrence-free survival (RFS) after resection. RESULTS: Of 1524 patients, 107 (7·0 per cent) were underweight, 891 (58·5 per cent) were of normal weight and 526 (34·5 per cent) were overweight. Univariable analyses showed that underweight and overweight patients had poorer OS (both P < 0·001) and RFS (both P < 0·001) than patients of normal weight. Multivariable Cox regression analysis also identified both underweight and overweight to be independent risk factors for OS (hazard ratio (HR) 1·22, 95 per cent c.i. 1·19 to 1·56, P = 0·019; and HR 1·57, 1·36 to 1·81, P < 0·001, respectively) and RFS (HR 1·28, 1·16 to 1·53, P = 0·028; and HR 1·34, 1·17 to 1·54, P < 0·001). CONCLUSION: Underweight and overweight patients appear to have a worse prognosis than those of normal weight following liver resection for HCC.

This study was conducted to estimate the prevalence and antimicrobial resistance rate of Ureaplasma spp. and Mycoplasma hominis that were isolated from the semen samples of infertile males in Shanghai, China from 2011 to 2016. A total of 5016 infertile males and 412 healthy male controls were examined. The cultivation, identification, and antimicrobial susceptibilities of Ureaplasma spp. and M. hominis were assessed by using a Mycoplasma IST kit that was performed in parallel to selective solid agar cultivation. The positive rate of genital Mycoplasma infections in infertile men from 2011 to 2016 was 30-55%, which initially decreased during the first four years and then increased in the last two. Two distinct high-risk age ranges of Mycoplasma infections were observed: 26-30 years (37.8%) and 31-35 years (30.7%). Semisynthetic tetracyclines and macrolide antibiotics were the most effective agents against Ureaplasma spp. Among the fluoroquinolones, sparfloxacin and levofloxacin were also effective. Antibiotic resistance of Ureaplasma spp. against tetracyclines and macrolide antibiotics in the last six years did not vary significantly. However, the rate of resistance to fluoroquinolones (except norfloxacin) and spectinomycin decreased in the last two years. The rate of genital Mycoplasma presence in infertile patients between the ages of 26 and 35 years in Shanghai was high. The prevalence of genital Mycoplasma decreased during the first four years and then increased, with a peak in 2016. Doxycycline, minocycline, josamycin, and sparfloxacin can be recommended for first-line empirical treatment of Mycoplasma infections in infertile men in Shanghai, China.

OBJECTIVES: To determine the performance of a rapid Chlamydia trachomatis (CT) test (Clearview Chlamydia MF) compared to the current "gold standard" (Roche Amplicor CT assay) test, and to assess acceptability of the tests to patients. METHODS: A total of 1497 women at sexually transmitted diseases (STD) clinics or re-education centres in six urban cities (Shanghai, Nanjing, Shenzhen, Guangzhou, Chengdu and Fuzhou) in China participated in the study. Three vaginal and three cervical swabs were collected from each participant. Rapid CT tests were performed locally on the first vaginal and cervical swabs and the results were read independently by two staff members. The second and third swabs were randomised for performing the Roche CT assay at the National STD Reference Laboratory. Acceptability of the rapid tests to patients was determined by asking patients in clinics about their willingness to wait for the results. RESULTS: The prevalence of CT was 13.2% (197/1497), as determined by the Roche assay with cervical specimens. CT was detected in 78 vaginal and 127 cervical specimens by the rapid test and the positive rates determined with cervical specimens were significantly higher than those with vaginal specimens (p<0.001). There was good agreement between the results read by two independent staff for either vaginal or cervical specimens (both kappa = 0.98, p<0.001). Sensitivities for vaginal and cervical specimens were 32.8% and 49.7%, respectively, and specificities were 99.2% and 97.9%, respectively. The positive predictive value was 85.7% for vaginal and 78.4% for cervical specimens. The vast majority of the patients (99.1%) were willing to wait up to two hours for the results. CONCLUSION: Clearview Chlamydia MF, while yielding a rapid result and requiring minimal laboratory facilities, had unacceptably low sensitivity compared to a nucleic acid amplification test. Rapid tests yielding results within one hour are generally accepted by the clients.
