Aims:The study aimed to identify the risk factors for catheter-associated urinary tract infection among hospitalized patients. We also tried to explore its potential effect on patient outcomes if possible.Background: Catheter-associated urinary tract infection accounts for a large proportion of healthcare-associated infections and remains a considerable threat to patient safety worldwide.Design: A systematic review and meta-analysis of observational studies. Data sources:We conducted an electronic search in PubMed, EMBASE, Web of Science, and the Cochrane Review methods: Two reviewers searched the articles and extracted the data independently. The quality of the studies was assessed with the Newcastle-Ottawa Scale. RevMan 5.3 was used to perform the meta-analysis.Results: Ten studies involving a total of 8785 participants with or without catheterassociated urinary tract infection were included. The average incidence of catheterassociated urinary tract infection was 13.79 per 1000 catheter days, with a prevalence rate of 9.33%. The meta-analysis demonstrated that patients at high risk for catheter-associated urinary tract infection were female, had a prolonged duration of catheterization, had diabetes, had previous catheterization, and had longer hospital and ICU stays. Additionally, catheter-associated urinary tract infection was also accompanied by an increase in mortality. Conclusions:Healthcare staff should focus on the identified risk factors for catheter-associated urinary tract infection. Further research is needed to investigate the microbial isolates and focus on the intervention strategies of catheter-associated urinary tract infection, so as to reduce its incidence and related mortality.

Microcantilever with integrated piezoresistor has been applied to in situ surface stress measurement in the field of biochemical sensors. It is well known that piezoresistive cantilever-based sensors are sensitive to ambient temperature changing due to highly temperature-dependent piezoresistive effect and mismatch in thermal expansion of composite materials. This paper proposes a novel method of temperature drift compensation for microcantilever-based sensors with a piezoresistive full Wheatstone bridge integrated at the clamped ends by subtracting the amplified output voltage of the reference cantilever from the output voltage of the sensing cantilever through a simple temperature compensating circuit. Experiments show that the temperature drift of microcantilever sensors can be significantly reduced by the method.

PURPOSE: The purpose of this study was to describe staff nurses' intestinal ostomy care practice in primary and secondary hospitals in China and their ostomy-related training needs. SUBJECTS AND SETTING: The target population for this study was first-line staff nurses working in general surgical departments in primary and secondary care hospitals in Luzhou, located in Sichuan Province, Southwest China. Hospitals in China are divided into 3 tiers; first tier facilities are usually located in townships and have fewer than 100 inpatients beds; secondary hospitals are usually found in medium-sized cities or districts and have between 100 and 500 inpatient beds. DESIGN: Descriptive, cross-sectional. METHODS: Participants were recruited through a stratified cluster sampling method based on hospital tier and the presence of general surgical department. Data were collected via a questionnaire that comprised 3 sections; the first section queried demographic and professional practice data, the second queried practice related to patients with intestinal ostomies, and the third queried nurses' stoma-related training needs. Links to the electronic survey were distributed through e-mail. RESULTS: Three hundred and eighteen nurses were invited to participate in the survey, and 280 questionnaires were returned, yielding a response rate of 88.05%. Review of data found that 214 questionnaires were sufficiently complete to be used in our data analysis. The mean intestinal ostomy practice score was 26.61 ± 7.98, indicating less than optimal engagement in ostomy care. Lack of manpower in the workplace and heavy workload of daily nursing were identified as leading barriers to continuing education in this area of practice. CONCLUSIONS: The ostomy-related practice of first-line staff nurses in Chinese primary and secondary hospitals showed less than optimal engagement in ostomy practice. We recommend creating additional ostomy-related continuing education targeted for nurses practicing in primary and secondary tier hospitals and removal of barriers to this education in order to improve ostomy care in primary and secondary tier hospitals in China.

Background: Gastrointestinal malignant tumors are the most common malignant tumors in elderly people in China, resulting in an increasing trend of morbidity and mortality. We conducted a non-randomized controlled trial to compare the effect of enhanced recovery after surgery (ERAS) versus Routine care on clinical outcomes in elderly patients after colorectal cancer surgery. Methods: This is a single center, non-random, parallel-controlled clinical trial, 60 patients aged ≥65 years will be randomized for Case group ERAS and Control group (routine care). Results: This study will help to evaluate the clinical feasibility, safety and effectiveness of ERAS in elderly patients undergoing colorectal resection compared with routine care.
