AI Article Synopsis
- The study investigates risk factors for urinary catheter associated bloodstream infection (UCABSI) to understand its impact on health and costs.
- It involved a case-control analysis comparing patients with UCABSI to those with indwelling urinary catheters who did not develop infections.
- Key findings highlighted significant risk factors such as catheter insertion in the operating room, chronic kidney disease, and dementia, suggesting improvements in catheter management could reduce infection rates.
Article Abstract
Objectives: Urinary catheter associated bloodstream infection (UCABSI) causes significant morbidity, mortality and healthcare costs. We aimed to define the risk factors for UCABSI.
Methods: A case-control study was conducted at two Australian tertiary hospitals. Patients with urinary source bloodstream infection associated with an indwelling urinary catheter (IDC) were compared to controls with an IDC who did not develop urinary source bloodstream infection.
Results: There were 491 controls and 67 cases included in the analysis. Independent statistically significant risk factors for the development of UCABSI included insertion of the catheter in operating theatre, chronic kidney disease, age-adjusted Charlson comorbidity index, accurate urinary measurements as reason for IDC insertion and dementia. IDCs were inserted for valid reasons in nearly all patients, however an appropriate indication at 48 h post-insertion was found in only 44% of patients. Initial empiric antibiotics were deemed inappropriate in 23 patients (34%).
Conclusion: To our knowledge, this is the first study to look specifically at the risk factors for bloodstream infection in urinary catheterised patients. Several risk factors were identified. IDC management and empiric management of UCABSI could be improved and is likely to result in a decreased incidence of infection and its complications.

In the Philippines, the co-occurrence of two or more types of malnutrition in an individual, also known as intra-individual double burden of malnutrition (DBM), has rarely been investigated. This study aimed to determine the prevalence of and the factors associated with DBM at the individual level among Filipino women of reproductive age (WRA) using the data collected from the 2018 Philippine Expanded National Nutrition Survey. For this study, intra-individual DBM was defined as the co-existence of overweight or obesity and anemia in an individual.

Background: Uric acid (UA) plays an important role in cardiovascular diseases, yet its implications in elderly patients remains incompletely understood. This study aimed to explore the impact of UA on the prognosis in advanced-age patients with acute coronary syndrome (ACS).
Methods: We included 526 patients aged 80 and older who were diagnosed with ACS.

The primary objective was to systematically assess the prevalence, incidence and risk factors of WSLs with orthodontic treatment. The secondary objective was to compare the prevalence of WSLs between conventional fixed appliances (CFA) and other appliances, as well as with no treatment. PubMed, Scopus, Web of Science, LILACs, Virtual Health Library and Cochrane CENTRAL were searched.
