RESUMO
OBJECTIVE: To determine if perioperative administration of dexmedetomidine affects postoperative fluid intake in tonsillectomy patients. METHODS: A retrospective chart review was performed at University Medical Center, Texas Tech Health Science Center, Lubbock, Texas. The study identified 534 patients within the last five years who met the criteria. Common indications for the surgeries included recurrent tonsillitis, obstructive sleep apnea, and sleep disordered breathing. Patients with concurrent peritonsillar abscess drainage, microlaryngoscopy, bronchoscopy, supraglottoplasty, and other procedures that may impact fluid intake were excluded. The relationship between dexmedetomidine and fluid intake was evaluated using bivariate analysis as well as multivariable regression to account for possible confounders such as age, concurrent medication, surgery type, and method of surgery using STATA statistical software, version 17.0 (StataCorp LLC, College Station, TX). RESULTS: Administration of dexmedetomidine did not significantly impact the amount of fluid intake, fluid intake per kilogram per hour, or average postoperative pain levels in patients who underwent tonsillectomy or adenotonsillectomy in the bivariate analysis (p = 0.217, 0.489, 0.512 respectively) and multiple regression model (p = 0.156, 0.802, 0.795) CONCLUSION: Dexmedetomidine does not negatively influence postoperative fluid intake levels in patients and should continue to be utilized in appropriately selected patients experiencing anxiety or agitation prior to surgery.
RESUMO
INTRODUCTION: Our goal was to systematically review the most commonly used validated questionnaires in recent global literature on stress urinary incontinence (SUI) treatment. METHODS: PubMed, Embase, and Ovid databases were queried for manuscripts containing "female stress urinary incontinence" AND "diagnosis" AND "treatment" AND "questionnaire." Two independent reviewers screened studies for randomized controlled trials, prospective, and retrospective studies between 2018 and 2023. Exclusion criteria included male participants, non-SUI incontinence, and articles not originally written in English. The review was registered in PROSPERO [465721] and conformed to PRISMA guidelines. RESULTS: In 117 manuscripts meeting study criteria, the median of the mean ages was 52 years, with a median of 164 participants per study. Most studies originated in Europe (59/117). The International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form was the most frequently used (52%), followed by the Patient Global Impression of Improvement (31%), the Urinary Distress Inventory 6 Short Form (25%), the Incontinence Quality of Life (20%), and the Incontinence Impact Questionnaire Short Form (19%). These leading questionnaires were short, translated into several languages, and globally addressed important SUI-related domains, including the presence and severity of SUI, additional lower urinary tract symptoms, and the impact of SUI on quality of life, as well as changes perceived after treatment. CONCLUSIONS: This systematic review of the validated questionnaires used in contemporary SUI management literature could help guide recommendations for incorporating these favored instruments into future SUI treatment outcome documents.
RESUMO
OBJECTIVE: To examine the global literature database on uncomplicated recurrent urinary tract infections (rUTI), this systematic review assesses the availability of rUTI data based on geographic region and elucidates the current state of research and gaps in knowledge. METHODS: The databases PubMed, Embase, WHO Global Index Medicus, and SciELO were searched for keywords related to rUTI between 2000 and 2023. Three independent reviewers screened studies restricted to female participants age ≥18 years with uncomplicated rUTIs. Studies were excluded if they did not provide a definition for rUTI or did not cite or report an estimate for rUTI prevalence. The review was registered in PROSPERO and conformed to PRISMA guidelines. RESULTS: The search yielded 2947 studies of which 124 were ultimately included. Convenience samples were used for 91% of studies and sample sizes were 30% n <50, 29% n = 50-99, 22% n = 100-199, 36% n ≥200. Most studies were conducted in Europe (41%) or North America (39%), were prospective (52%), at tertiary centers (49%) and included all ages ≥18 (60%). The most common definition for rUTI was 2 UTI/6 m or 3 UTI/1y (62%). Regardless of study location, most studies cited prevalence estimates for rUTI derived from U.S.-based populations. CONCLUSION: This study represents the first formal investigation of the global literature base on uncomplicated rUTI. Studies on rUTIs are globally of small scale and definitions used for rUTI are heterogeneous. More studies are needed to ascertain the true prevalence of rUTI outside of North America and Europe.
RESUMO
Urinary tract infections (UTIs), mostly caused by uropathogenic E. coli (UPEC), affect most women, and often recur. Genomic and transcriptomic analyses have not identified a common set of virulence genes, which has suggested complex host-pathogen interactions and multiple virulence mechanisms. One aspect of the host-pathogen interaction is rapid UPEC growth in urine in vivo. When bacterial growth in urine is studied in vitro, urine is pooled, which is assumed to diminish individual variation. We grew one nonpathogenic and two pathogenic E. coli strains in urine from individuals who never had a UTI, had a UTI history but no current infection, and had a UTI history with a current infection. Bacterial growth showed large variations in individual urine samples, and pooled urine often supported significantly more growth than the average growth from individual urine samples. Total nutrient content tended to be higher in current group urine samples than the never and history grouped samples urine. We propose that pooling optimizes a nutrient mixture in the never and history group urine samples, which are often studied, whereas urine from current group individuals may have a more optimal nutrient mixture because of additional nutrient sources. We conclude that a pooled urine is not "an average urine sample," and that the best comparisons of results between labs using pooled urine would also include results with a standardized synthetic urine. IMPORTANCE Urinary tract infections (UTIs) will affect most women, can recur especially in postmenopausal women, and can become antibiotic recalcitrant. Escherichia coli causes most community-acquired UTIs and recurrent UTIs. Current theories of virulence, based on studies of UTI-associated E. coli, propose multiple virulence mechanisms and complex host-pathogen interactions. Studies of bacterial growth in urine samples-one aspect of the host-pathogen interaction-invariably involve pooled urine that are assumed to eliminate variations between individuals. Our results show that a pooled urine is not necessarily an average urine sample, and we suggest that quantitative and qualitative variations in nutrient content are the basis for this discrepancy. Knowledge of growth-promoting urinary components is important for understanding host-pathogen interactions during UTIs and could contribute to developing nonantibiotic-based therapies.
