Epidemiology of pathogens causing urinary tract infections in an urban community in southern Brazil.

Epidemiology of pathogens causing urinary tract infections in an urban community in southern Brazil. Braz J Infect Dis. 2018 Dec 05;: Authors: Reu CE, Volanski W, Prediger KC, Picheth G, Fadel-Picheth CMT Abstract The frequency of urinary tract infection (UTI) and uropathogens in the community was determined by assessing urine culture results of outpatients at a Brazilian public laboratory in a year period. Patients were classified according to sex and age; women were additionally classified considering pregnancy or diabetes. Cultures were considered positive when growing pure cultures with colony counts>104CFU/mL. Of the 64,562 urine cultures performed 11,122 (17.2%) turned out positive. UTI was significantly more common among women; however, its frequency varied among patient subgroups. The most common uropathogens were Escherichia coli (54.7%), Streptococcus agalactiae (18.8%), and Proteus mirabilis (5.6%). E. coli frequency was higher among women; even though pregnant women showed a lower incidence (41.1%), similar to that observed in adult men (40.9%). S. agalactiae was the second most commonly isolated species among women, with a higher incidence among pregnant women (31.2%). In contrast, P. mirabilis was the most common species recovered from boys (32%). These data indicate that the distribution of uropathogens varies among groups of patients suggesting that host characteristics may be associated with greater susceptibility to specific uropatho...

Conclusions: The constantly increasing prevalence of NAFLD in the general population can contribute to a growing role of NAFLD/NASH in HCC epidemiology. Moreover, some particular challenges specific for patients with liver steatosis may impede proper HCC diagnosis, treatment and follow-up. PMID: 31631714 [PubMed - as supplied by publisher]

CONCLUSIONS: Although consumption of a WPND was associated with a larger estimated GV in this pilot study, a larger study is necessary to conclude whether patients must fast longer than 2 hours after consumption of a WPND. PMID: 31630511 [PubMed - as supplied by publisher]

CONCLUSIONS: In elderly individuals with T1DM, we found associations between dLOC and cognition overall and in men but not women. Underlying sex differences should be considered in future research or interventions on psychosocial characteristics for cognition. PMID: 31633555 [PubMed - as supplied by publisher]

This study also found that Proteus DNA, a genus with many uropathogenic species (Drzewiecka, 2016), was more prevalent in women with OAB compared to asymptomatic controls (Curtiss et al., 2017). IC A recent study by Abernethy et al. suggested that the microbiome may play a role in IC (Abernethy et al., 2017). In this study, 16S rRNA analysis determined the microbiome of catheterized urine from women (n = 40) with IC was not dominated by a single genus and was less likely to contain Lactobacillus compared to asymptomatic women. Abernethy et al. also showed that L. acidophilus was associated with less severe scores on the ...

Discussion Fatigue is a subjective feeling of decreased energy, tiredness or feeling of exhaustion. Lethargy is often used synonymously, but lethargy is a state of being drowsiness or sleepy, and implies mental status changes. Both can cause the person to be apathetic or less active. Fatigue is a common state that almost everyone experiences multiple times in his or her lifetime. For most people it is a relatively acute or short-term chronic problem, often with a relatively easily identifiable problem cause, such as inadequate sleep, acute illness, or overexertion. For some, it can be less readily identifiable such as dep...

Here is a closer look at five of the many benefits of making probiotics a regular part of your diet. 1. Soothes Indigestion Probiotics have been shown to play a role in preventing and relieving various ty...

CONCLUSION: The distribution of germs in our study is comparable to the literature, however, antibiotic resistance is higher in our study, which is probably a result of the inappropriate use of these drugs in our country, therefore it is important for us to create a good strategy to supply and distribute these drugs, as well as the review of the empirical treatment of UTI in our country.
