BACKGROUND: The most common sites of malignant mesothelioma are the pleura and peritoneum, but little is known about the incidence, prognosis, or treatment of patients with disease in both cavities. Previous series suggest that multimodality treatment improves overall survival for pleural or peritoneal disease, but studies typically exclude patients with disease in both cavities. Despite limitations, this investigation is the only study to broadly examine outcomes for patients with malignant mesothelioma in both the pleural and peritoneal cavities. METHODS: This study retrospectively examined 50 patients with both pleural and peritoneal mesothelioma treated with the intent to prolong survival. The primary end point was overall survival from the initial operative intervention. RESULTS: The median overall survival was 33.9 months from the initial intervention. Female gender and intraperitoneal dwell chemotherapy were independent predictors of overall survival. Within 1 year after the initial diagnosis, second-cavity disease was diagnosed in 52% of the patients. The median time to the second-cavity diagnosis for those with a diagnosis 1 year after the initial diagnosis was 30 months. CONCLUSIONS: Well-selected patients with both pleural and peritoneal mesothelioma have a survival benefit over palliative treatment that is comparable with that seen in single-cavity disease. The presence of disease in both cavities is not a contraindication to multimodality treatment aimed at prolonging survival, whether the disease is diagnosed synchronously or metachronously. Patients with an initial diagnosis of single cavity disease are at the highest risk for identification of second-cavity disease within the first year after diagnosis.

MOTIVATION: Catheter-associated urinary tract infections (CAUTI) are a common and serious healthcare-associated infection. Despite many efforts to reduce the occurrence of CAUTI, there remains a gap in the literature about CAUTI risk factors, especially pertaining to the effect of catheter dwell-time on CAUTI development and patient comorbidities. OBJECTIVE: To examine how the risk for CAUTI changes over time. Additionally, to assess whether time from catheter insertion to CAUTI event varied according to risk factors such as age, sex, patient type (surgical vs medical) and comorbidities. DESIGN: Retrospective cohort study of all patients who were catheterised from 2012 to 2016, including those who did and did not develop CAUTIs. Both paediatric and adult patients were included. Indwelling urinary catheterisation is the exposure variable. The variable is interval, as all participants were exposed but for different lengths of time. SETTING: Urban academic health system of over 2500 beds. The system encompasses two large academic medical centres, two community hospitals and a paediatric hospital. RESULTS: The study population was 47 926 patients who had 61 047 catheterisations, of which 861 (1.41%) resulted in a CAUTI. CAUTI rates were found to increase non-linearly for each additional day of catheterisation; CAUTI-free survival was 97.3% (CI: 97.1 to 97.6) at 10 days, 88.2% (CI: 86.9 to 89.5) at 30 days and 71.8% (CI: 66.3 to 77.8) at 60 days. This translated to an instantaneous HR of. 49%-1.65% in the 10-60 day time range. Paraplegia, cerebrovascular disease and female sex were found to statistically increase the chances of a CAUTI. CONCLUSIONS: Using a very large data set, we demonstrated the incremental risk of CAUTI associated with each additional day of catheterisation, as well as the risk factors that increase the hazard for CAUTI. Special attention should be given to patients carrying these risk factors, for example, females or those with mobility issues.
