Microbiological and microstructural analysis of indwelling bladder catheters and urinary tract infection prevention.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo analyze the microbiological and microstructural part of indwelling urinary catheters and their association with urinary tract infection prevention.
methodThis is a cross-sectional study, from June to December 2020, in which 42 indwelling urinary catheter tips and sterile urine samples were collected for analysis of crystals in optical microscopy and biofilms in scanning electron microscopy. Culture analysis and specification of the type of bacteria were performed.
resultsIt was found that 35.71% of the samples had mature biofilm adhered to the catheter tip. Biofilms of Proteus mirabilis, Enterococcus faecalis, Staphylococcus epidermidis, Enterococcus faecium and Enterobacter cloacae stood out. The presence of magnesium-ammonium-phosphate crystal was associated with the presence of urinary tract infection and with Proteus mirabilis. There was a significant association (p = 0.001) between the use of prophylactic antibiotics versus urine culture >105 CFU/mL.
conclusionThe analyzes contributed to clinical practice, as it reinforces the development of effective and monitored strategies on cultures and urinary tract infection prevention associated with indwelling urinary catheters.
