The influence of delay elimination communication on the prevalence of primary nocturnal enuresis-a survey from Mainland China.

AIMS: A pilot survey shows that primary nocturnal enuresis (PNE) prevalence has increased significantly during the past decade in Mainland China. Whether it is related to the delay of elimination communication (EC) is unclear. This study retrospectively investigated the influence of delayed EC on the PNE prevalence in children and adolescents in mainland China. METHODS: A cross-sectional study of PNE prevalence was performed by distributing 19 500 anonymous self-administered questionnaires to parents in five provinces of mainland China from July 2017 to October 2017. The questionnaires included sociodemographic data, family caregivers' information, and details about the disposable diapers (DD) usage, EC commencement date, psychological disorders, lower urinary tract symptoms, and family history of PNE in children and adolescents. The 2017 PNE prevalence was compared with that of 2006 in Mainland China. RESULTS: The total response rate was 97.04% (18 631 of 19 500) and 92.39% (18 016 of 19 500) qualified for statistical analysis. The PNE prevalence in 2017 has increased significantly compared to that of 2006 (7.30% vs 4.07%, P < 0.001). The PNE prevalence in children with EC starting before 6 months of age was significantly lower than those who start after 12 months of age. The longer DD were used and the later the beginning of EC, the higher the PNE prevalence was found. CONCLUSIONS: The PNE prevalence in Mainland China has increased significantly during the past 10 years. A longer use of DD and later onset of EC may be risk factors for PNE.

Comparison of Pressure- and Volume-Controlled Ventilation in Laparoscopic Surgery: A Meta-analysis of Randomized Controlled Trial.

PURPOSE: Volume-controlled ventilation (VCV) has been the traditional mechanical ventilation mode in laparoscopic surgery. Pressure-controlled ventilation (PCV) has been used more frequently in recent years, especially for patients with complicated conditions; however, evidence on whether PCV is superior to VCV is still lacking. A meta-analysis was used to compare the effects of PCV and VCV on respiratory and hemodynamic parameters during laparoscopic surgery. METHODS: PubMed and Embase were each searched from their inception to December 2014 for randomized controlled trials comparing the effects of PCV and VCV on respiratory and hemodynamic parameters during laparoscopic surgery. Standard mean difference (SMD) with 95% confidence interval (CI) was calculated using a random effect model. Outcomes were assessed at three times: preoperative (T1), intraoperative (T2) and postoperative (T3). Respiratory mechanics (including peak airway pressure, plateau pressure, mean airway pressure, compliance, airway resistance, minute volume, end-tidal CO2 tension and tidal volume) and hemodynamic parameters (including heart rate and mean arterial pressure) were calculated. RESULTS: Eight randomized controlled trials with a total of 428 participants, 214 cases using PCV and 214 cases using VCV, were included in the meta-analysis. No significant differences were detected between the groups in terms of hemodynamic parameters. In contrast, with respiratory mechanics, PCV was slightly but significantly associated with lower peak airway pressure, higher compliance, lower airway resistance at T1, lower peak airway pressure, higher compliance, higher mean airway pressure at T2, lower peak airway pressure, lower mean airway pressure and higher end-tidal CO2 tension at T3. For the rest of respiratory parameters, there were no statistical differences between the groups. Subgroup analysis by morbidly obese, type of operations and quality of studies, showed similar results. CONCLUSIONS: Our meta-analysis suggests that hemodynamic parameters are similar in patients who underwent laparoscopic surgery with PCV and VCV, but patients who had PCV exhibited mildly better respiratory data.

Effectiveness of combining plasma exchange with plasma perfusion in acute fatty liver of pregnancy: a retrospective analysis.

BACKGROUND/AIMS: Acute fatty liver of pregnancy (AFLP) is a severe liver failure condition that has limited therapeutic approaches. We aimed to evaluate the efficacy of combining plasma exchange (PE) and plasma perfusion (PP) with conventional therapy for the treatment of AFLP using a retrospective analysis. METHODS: Among 22 patients with AFLP, 16 cases were treated with conventional treatment (CT group), while the other 6 cases were treated with PE and PP in addition to conventional therapy (CT+PE+PP group). Treatment efficacy was based primarily on survival and secondarily on liver and kidney functions 2 weeks after treatment. Adverse effects were also assessed at the same time point. RESULTS: In the CT+PE+PP group, 5 (83.3%) patients improved, while 1 (16.7%) patient died of multiple organ dysfunction syndrome. In the CT group, 3 (18.75%) patients improved, while 13 (81.2%) patients died of complications. Liver and kidney functions and survival were significantly improved in the CT+PE+PP group (p < 0.05) compared to the CT group. CONCLUSIONS: Timely application of PE and PP in the early phase of AFLP may be a promising treatment to halt or reverse the progression of AFLP.

Evaluating ECG-aided tip localization of peripherally inserted central catheter in patients with cancer.

OBJECTIVE: To evaluate ECG-aided tip localization of peripherally inserted central catheter (PICC) in the patients with cancer. METHODS: Between September and December 2014, 170 patients undergoing PICC were divided into observation group and control group (each group with 85 patients). In observation group, patients received ECG-aided tip localization of PICC. In control group, PICC was performed with conventional method. After PICC was performed, all patients took orthophoria chest radiograph (OCR) to check whether the tip position of PICC was appropriate. Finally, successful rate of the first PICC was compared between the two groups. RESULTS: In observation group, OCR showed that the tip of PICC was located in middle and low one-third of superior vena cava in 85 patients. In control group, OCR showed that the tip of PICC was located between superior vena cava and right atrium in 75 patients. The successful rate of the first PICC was significantly higher in observation group than in control group (P < 0.05). CONCLUSION: ECG-aided tip localization of PICC is accurate and safe, and is worth clinically recommending.

Comparison of short-term efficacy and safety of TIROX and DCF regimens for advanced gastric cancer.

OBJECTIVE: To compare the short-term efficacy and safety profile of the S-1 + irinotecan + oxaliplatin (TIROX) and docetaxel + cisplatin + flurouracil (DCF) anticancer regimens in patients with advanced gastric cancer. METHODS: Patients with recurrent or metastatic gastric cancer diagnosed by pathology were randomly divided into two groups to receive six cycles of either the TIROX regimen (21-day cycle) or the DCF regimen (21-day cycle). After six chemotherapy cycles, the short-term efficacy was evaluated according to the Response Evaluation Criteria in Solid Tumors guidelines and adverse reactions were recorded according to National Cancer Institute Common Toxicity Criteria 2.0 standards. RESULTS: A total of 60 patients were enrolled in the study. The response rate (complete response + partial response) was significantly higher in the TIROX group (18/30 patients; 60.0%) compared with the DCF group (10/30 patients; 33.3%). The rates of grade III-IV leucopenia and neurotoxicity were significantly higher in the TIROX group than the DCF group. CONCLUSION: The TIROX regimen was effective for the treatment of advanced gastric cancer, but it was associated with leucopenia and neurotoxicity.
