RESUMO
Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.
Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.
Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas.

O objetivo deste estudo é conhecer as características do uso do cateterismo urinário em pacientes internados em enfermarias de cuidados moderados de um hospital universitário terciário, determinar a frequência, duração e indicações mais frequentes, bem como avaliar a presença de complicações associadas ao mesmo. Metodologia: Estudo transversal, realizado em quartos de cuidados moderados de um hospital terciário e universitário em Montevidéu, Uruguai, em 21 de dezembro de 2022. Foram incluídos pacientes que apresentaram ou apresentaram sonda vesical durante a internação atual e a coleta de variáveis ââfoi concluída .revisando o histórico médico. Resultados: Dos 155 pacientes admitidos em enfermarias de cuidados moderados, 26 (16,7%) tiveram um cateter urinário colocado. A idade média foi de 61 anos, 80% eram do sexo masculino. A mediana de internação foi de 22 dias. Em todos os doentes foi utilizada sonda vesical e 54% foram internados no Serviço de Urgência. Em 46% dos pacientes, nenhuma indicação escrita para colocação foi encontrada na história clínica. Em 50% dos casos não é especificado o motivo da indicação da sonda vesical, enquanto as indicações mais frequentes identificadas foram controle da diurese (27%) e desobstrução do trato urinário inferior (23%). A duração do cateterismo foi em média de 13,5 dias, enquanto 27% dos pacientes o utilizaram por mais de 30 dias. 35% dos pacientes apresentaram complicações relacionadas ao cateter vesical, em sua maioria não infecciosas (27%) e 15% apresentaram infecção urinária. Esses pacientes tiveram uma duração mais longa de cateterismo do que aqueles sem complicações (23 vs 10 dias, p=0,411). Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.
RESUMO
Overuse of antimicrobials has greatly contributed to the increase in the emergence of multidrug-resistant bacteria, a situation that hinders the control and treatment of infectious diseases. This is the case with urinary tract infections (UTIs), which represent a substantial percentage of worldwide public health problems, thus the need to look for alternatives for their control and treatment. Previous studies have shown the usefulness of autologous bacterial lysates as an alternative for the treatment and control of UTIs. However, a limitation is the high cost of producing individual immunogens. At the same time, an important aspect of vaccines is their immunogenic amplitude, which is the reason why they must be constituted of diverse antigenic components. In the case of UTIs, the etiology of the disease is associated with different bacteria, and even Escherichia coli, the main causal agent of the disease, is made up of several antigenic variants. In this work, we present results on the study of a bacterial lysate composed of 10 serotypes of Escherichia coli and by Klebsiella pneumoniae, Klebsiella aerogenes, Enterococcus faecalis, Proteus mirabilis, Citrobacter freundii, and Staphylococcus haemolyticus. The safety of the compound was tested on cells in culture and in an animal model, and its immunogenic capacity by analysing in vitro human and murine macrophages (cell line J774 A1). The results show that the polyvalent lysate did not cause damage to the cells in culture or alterations in the animal model used. The immunostimulatory activity assay showed that it activates the secretion of TNF-α and IL-6 in human macrophages and TNF-α in murine cells. The obtained results suggest that the polyvalent lysate evaluated can be an alternative for the treatment and control of chronic urinary tract infections, which will reduce the use of antimicrobials.

Background: Urinary tract infections (UTIs) are very common worldwide. According to their symptomatology, these infections are classified as pyelonephritis, cystitis, or asymptomatic bacteriuria (AB). Approximately 75-95% of UTIs are caused by uropathogenic Escherichia coli (UPEC), which is an extraintestinal bacterium that possesses virulence factors for bacterial adherence and invasion in the urinary tract. In addition, UPEC possesses type 6 secretion systems (T6SS) as virulence mechanisms that can participate in bacterial competition and in bacterial pathogenicity. UPEC UMN026 carries three genes, namely, ECUMN_0231, ECUMN_0232, and ECUMN_0233, which encode three uncharacterized proteins related to the T6SS that are conserved in strains from phylogroups B2 and D and have been proposed as biomarkers of UTIs. Aim: To analyze the frequency of the ECUMN_0231, ECUMN_0232, ECUMN_0233, and vgrG genes in UTI isolates, as well as their expression in Luria Bertani (LB) medium and urine; to determine whether these genes are related to UTI symptoms or bacterial competence and to identify functional domains on the putative proteins. Methods: The frequency of the ECUMN and vgrG genes in 99 clinical isolates from UPEC was determined by endpoint PCR. The relationship between gene presence and UTI symptomatology was determined using the chi2 test, with p < 0.05 considered to indicate statistical significance. The expression of the three ECUMN genes and vgrG was analyzed by RT-PCR. The antibacterial activity of strain UMN026 was determined by bacterial competence assays. The identification of functional domains and the docking were performed using bioinformatic tools. Results: The ECUMN genes are conserved in 33.3% of clinical isolates from patients with symptomatic and asymptomatic UTIs and have no relationship with UTI symptomatology. Of the ECUMN+ isolates, only five (15.15%, 5/33) had the three ECUMN and vgrG genes. These genes were expressed in LB broth and urine in UPEC UMN026 but not in all the clinical isolates. Strain UMN026 had antibacterial activity against UPEC clinical isolate 4014 (ECUMN-) and E. faecalis but not against isolate 4012 (ECUMN+). Bioinformatics analysis suggested that the ECUMN genes encode a chaperone/effector/immunity system. Conclusions: The ECUMN genes are conserved in clinical isolates from symptomatic and asymptomatic patients and are not related to UTI symptoms. However, these genes encode a putative chaperone/effector/immunity system that seems to be involved in the antibacterial activity of strain UMN026.

We assessed 160 patients who received imipenem/cilastatin/relebactam for ≥2 days. At treatment initiation, the median Charlson Comorbidity Index was 5, 45% were in the intensive care unit, and 19% required vasopressor support. The in-hospital mortality rate was 24%. These data advance our understanding of real-world indications and outcomes of imipenem/cilastatin/relebactam use.

BACKGROUND: The association between obesity and infectious diseases is increasingly reported in the literature. There are scarce studies on the association between obesity and urinary tract infection after kidney transplantation (KTx). These studies defined obesity based on body mass index, and their results were conflicting. The present study aimed to evaluate this association using bioelectrical impedance analysis for body composition evaluation, and obesity definition. METHODS: A single-center cohort study was conducted. Demographic, clinical, anthropometric, and laboratory data were collected at KTx admission, and bioelectrical impedance analysis was performed to measure the visceral fat area, waist circumference, and total fat mass. The occurrence of urinary tract infection (symptomatic bacteriuria and/or histological evidence of pyelonephritis) was evaluated within three months after KTx. RESULTS: Seventy-seven patients were included in the cohort, and 67 were included in the final analysis. Urinary tract infection was diagnosed in 23.9% of the transplanted patients. Waist circumference (HR: 1.053; 95% CI 1.005-1.104; p = 0.032), visceral fat area (HR: 1.015; 95% CI 1.003-1.027; p = 0.014), and total fat mass (HR: 1.075; 95% CI 1.008-1.146; p = 0.028) were associated with urinary tract infection occurrence after KTx, using Cox regression models. Patients with high waist circumference (above 102 cm for men and above 88 cm for women) had a 4.7 times higher risk of a urinary tract infection than those with normal waist circumference (HR: 4.726; 95% CI 1.267-17.630; p = 0.021). Kaplan-Meier curves showed that patients with high waist circumference, high visceral fat area, and high total fat mass had more urinary tract infections (Log-rank test p = 0.014, p = 0.020, and p = 0.018, respectively). Body mass index was not able to predict urinary tract infection in the study sample. CONCLUSIONS: Waist circumference, visceral fat area, and total fat mass, assessed by bioelectrical impedance analysis, were predictors of urinary tract infection risk within the first three months after KTx.

The aim of this study was to evaluate the effect of inappropriate therapy in adult patients with community-acquired pyelonephritis caused by Escherichia coli receiving empirical treatment with cefuroxime during hospital stay and readmission. A retrospective cohort study was performed. Inappropriate treatment was considered treatment for a nonsusceptible isolate according to the results of the urine culture. Adjustment for confounding factors was performed with propensity score-derived inverse probability of treatment weighting. Between 2013 and 2020, 747 patients were included, 102 (13.7%) of whom received inappropriate therapy. Compared to appropriate therapy, inappropriate therapy was associated with a shorter length of stay in the adjusted analysis (Hazard Ratio = 0.34; 95% CI = 0.23-0.49). After 735 patients were discharged from the hospital, 66 were readmitted in the following 30 days. In comparison with appropriate therapy, inappropriate antimicrobial therapy was not related to readmission (OR 1.47; 95% CI = 0.35-2.79). Inappropriate therapy was not related to a longer hospital stay or readmission due to pyelonephritis after adjusting for confounders and covariates.
RESUMO
OBJECTIVE: This study aimed to compare the effects of bladder diverticula smaller than 30 (SD) mm and larger than 30 mm (LD) on bladder functions and urodynamics. MATERIALS AND METHODS: Our retrospective analysis involved a cohort of 40 pediatric patients diagnosed with primary bladder diverticula. RESULTS: The predicted mean bladder capacity (MBC) was 197.7 ± 95.8 mL, whereas the observed MBC was lower at an average of 170.1 ± 79.6 mL. This indicates that the observed MBC was 88.2 ± 12.9% of the predicted value (percentage). The mean diverticula diameter recorded was 33 ± 19.5 mm, and the diverticula to MBC ratio were calculated to be 0.25 ± 0.18. The distribution of urinary tract infections (UTIs) differed significantly between the groups (p < 0.001). Upper UT dilatation was significantly more common in the LD group (60%, n = 12) than in the SD group (15%, n = 3) (p = 0.003). The mean detrusor pressure (P[detrusor]) was significantly higher in the LD group (137.2 ± 24.1 cm H2O) than in the SD group (63.9 ± 5.8 cm H2O) (p = 0.001). In addition, the mean peak flow rate (Qmax) was significantly higher in the SD group (20.7 ± 7.9 mL/s) compared to the LD group (12.7 ± 3.8 mL/s) (p < 0.001). CONCLUSION: Bladder diverticula size is a significant factor in the clinical presentation and management of primary bladder diverticula in pediatric patients.

MATERIALES Y MÉTODOS: Nuestro análisis retrospectivo involucró una cohorte de 40 pacientes pediátricos diagnosticados con divertículos vesicales primarios. RESULTADOS: Capacidad vesical media predicha (MBC) fue de 197.7 ± 95.8 mL, mientras que MBC observada fue menor con promedio de 170.1 ± 79.6 mL. Esto indica que MBC observada fue del 88.2 ± 12.9% del valor predicho (porcentaje). Diámetro medio de divertículos registrados fue de 33 ± 19.5 mm, y se calculó que relación entre los divertículos y la MBC era de 0.25 ± 0.18. Distribución de infecciones del tracto urinario (ITU) difirió significativamente entre grupos (p < 0.001). Dilatación del tracto urinario superior (UT) fue significativamente más común en grupo LD (60%, n = 12) que en grupo SD (15%, n = 3) (p = 0.003). Presión media del detrusor (P[detrusor]) fue significativamente mayor en grupo LD (137.2 ± 24.1 cm H2O) que en grupo SD (63.9 ± 5.8 cm H2O) (p = 0.001). Además, tasa de flujo máximo promedio (Qmax) fue significativamente mayor en grupo SD (20.7 ± 7.9 mL/seg) en comparación con grupo LD (12.7±3.8 mL/seg) (p < 0.001). CONCLUSIONES: Tamaño de divertículos vesicales es factor significativo en presentación clínica, manejo de divertículos vesicales primarios en pacientes pediátricos.

RESUMO
Purpose: To conduct a systematic literature review with meta-analysis to identify whether antibiotic prophylaxis after removal of the indwelling urinary catheter reduces posterior infections. Methods: A systematic literature review was conducted in the databases PubMed, Embase, Cochrane, Google Scholar, and Latin American and Caribbean Health Sciences Literature, using the keywords "antibiotics" AND "prostatectomy" AND "urinary catheter." Results: Three articles were identified having the scope of our review, with 1,040 patients, which were subjected to our meta-analysis revealing a marginally significant decrease in the risk of urinary infection after indwelling urinary catheter removal (odds ratio-OR = 0.51; 95% confidence interval-95%CI 0.27-0.98; p = 0.04; I2 = 0%). No difference was found regarding the presence of bacteriuria (OR = 0.39; 95%CI 0.12-1.24; p = 0.11; I2 = 73%). Conclusions: In our meta-analysis, there was a significant decrease in urinary tract infection with antibiotic prophylaxis after indwelling urinary catheter removal following radical prostatectomy.

Introduction: Urinary tract infections (UTI) are the most frequent infection in kidney transplant (KT) patients. The main objective was to determine the clinical and microbiological characteristics of UTIs that occur during the first year after KT. Methods: Retrospective cohort study that included patients over 18 years of age who received KT between 2009-2020 in two hospitals in Córdoba city, Argentina. Patients were followed up during the first year after the transplant by recording them in the medical records, and those who presented at least one episode of UTI were analyzed. Results: During the study period, 568 KTs were performed, of which 207 (36.4%) had at least one episode of UTI. In total, there were 419 UTI episodes, 6 (1.4%) polymicrobial UTI episodes, so a total of 426 microorganisms were identified in the urine cultures. Of the total number of episodes, 206 (49.2%) occurred between 31 and 180 days post-transplant. The main etiological agent was E. coli with 225 isolates (52.8%) followed by Klebsiella sp. with 94 (22.1%). 52.1% of all episodes were caused by multi-resistant microorganisms (MRM). Among the E. coli isolates, 94 (41.8%) were MRM. In the multivariate analysis, the risk factors associated with UTI due to MRM were a history of recurrent UTI (Odds ratio 2.43; 95% CI: 1.37-4.30) and induction with basiliximab (Odds ratio 1.53; 95% CI: 1.029-2.29). Main conclusion: UTIs occurred in more than a third of kidney transplant patients, being slightly more than half caused by MOR.

Metodología: Estudio de cohorte retrospectivo, donde se incluyeron pacientes mayores 18 años que recibieron un TR entre 2009-2020 en dos hospitales de la ciudad de Córdoba. A través del registro en las historias clínicas se realizó seguimiento de los pacientes durante el primer año postrasplante y se analizaron los que presentaron al menos un episodio de ITU. Resultados: En el período de estudio, se realizaron 568 TR, de los cuales 207(36,4%) tuvieron al menos un episodio de ITU. En total hubo 419 episodios de ITU, 6(1,4%) episodios de ITU polimicrobianos, se identificaron un total de 426 microorganismos en total en los urocultivos. Del total de episodios 206(49,2%) ocurrieron entre los 31-180 días postrasplante. El principal agente etiológico fue E. coli con 225 aislamientos (52,8%) seguido de Klebsiella sp. con 94(22,1%). El 52,1% del total de episodios fueron causados por microorganismos multirresistentes (MOR). Entre los aislamientos de E. coli, 94(41,8%) fueron MOR. En el análisis multivariado los factores de riesgo asociados a ITU por MOR fueron el antecedente de ITU recurrente (Odds ratio 2.43; IC95%: 1.37-4.30) e inducción con basiliximab (Odds ratio 1.53; IC95%: 1.029-2.29). Conclusión: Las ITU se presentaron en más de un tercio de los pacientes trasplantados renales siendo un poco más de la mitad causados por MOR.

BACKGROUND: Given the physiological changes during pregnancy, pregnant women are likely to develop recurrent urinary tract infections (UTIs) and pyelonephritis, which may result in adverse obstetric outcomes, including prematurity and low birth weight preeclampsia. However, data on UTI prevalence and bacterial profile in Latin American pregnant women remain scarce, necessitating the present systematic review to address this issue. METHODS: To identify eligible observational studies published up to September 2022, keywords were systematically searched in Medline/PubMed, Cochrane Library, Embase, Web of Science, and Bireme/Lilacs electronic databases and Google Scholar. The systematic review with meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the quality of studies was classified according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. The meta-analysis employed a random-effects method with double-arcsine transformation in the R software. RESULTS: Database and manual searches identified 253,550 citations published until September 2022. Among the identified citations, 67 met the inclusion criteria and were included in the systematic review, corresponding to a sample of 111,249 pregnant women from nine Latin American countries. Among Latin American pregnant women, the prevalence rates of asymptomatic bacteriuria, lower UTI, and pyelonephritis were estimated at 18.45% (95% confidence interval [CI]: 15.45-21.53), 7.54% (95% CI: 4.76-10.87), and 2.34% (95% CI: 0.68-4.85), respectively. Some regional differences were also detected. Among the included studies, Escherichia coli (70%) was identified as the most frequently isolated bacterial species, followed by Klebsiella sp. (6.8%). CONCLUSION: Pregnant women in Latin America exhibit a higher prevalence of bacteriuria, UTI, and pyelonephritis than pregnant women globally. This scenario reinforces the importance of universal screening with urine culture during early prenatal care to ensure improved outcomes. Future investigations should assess the microbial susceptibility profiles of uropathogens isolated from pregnant women in Latin America. TRIAL REGISTRATION: This research was registered at PROSPERO (No. CRD42020212601).

INTRODUCTION AND HYPOTHESIS: Dysuria is a common symptom present in several urological and gynecological conditions. Management relies on the underlying disease but may require additional symptomatic treatment. This study evaluated the combination of methenamine 250 mg and methylthioninium chloride 20 mg in the treatment of dysuria versus phenazopyridine. METHODS: This was a multicenter, single-blind, randomized, superiority clinical trial, including individuals over 18 with dysuria and a score ≥ 5 points on the pre-treatment categorical scale for pain. The primary outcome was the proportion of participants presenting excellent clinical response within 24 h after treatment. Improvement up to 72 h, time to reach improvement, sustained healing, investigators' opinion, and safety were also evaluated. RESULTS: Three hundred and fifteen participants were evaluated. Demographic characteristics and symptoms of dysuria were comparable between groups at baseline. The difference in the excellent response rate between treatments within 24 h was 12.7% (95% CI 6.16, 19.21) for pain, 9.4% (95% CI 3.32, 15.39) for burning, and 12.7% (95% CI 6.37, 18.99) for burning on urination, all in favor of the test drug, which was also superior from 36 to 48 h. Treatments were similar concerning time to reach the absence of symptoms and in the percentage of participants with sustained healing after 72 h. CONCLUSIONS: The association of methenamine with methylthioninium is superior to phenazopyridine in the treatment of dysuria.

Background: Urinary tract infections (UTIs) are the most prevalent in pregnant women. There are associated risk factors that predispose the acquisition of a UTI in pregnancy, which can cause serious complications for mother and child. Objective: To determine the prevalence of UTI and associated risk factors in pregnant women at the Hospital Básico de Sangolquí. Material and methods: Observational, cross-sectional, analytical study conducted in 570 pregnant women from January 1 2021 to August 30 2022. The prevalence and risk factors associated with UTI were analyzed through 95% confidence intervals (95% CI) and odds ratio (OR) calculation. Results: The global prevalence of UTI in pregnant women was 37.7% (IC 95% 33.7-41.7). The most frequent etiology was Escherichia coli (65.4%), followed by Staphylococcus spp. (21.8%). The age of pregnant women ranged from 12 to 45 years, with an average of 27.55 ± 7 years, out of which those with a previous history of UTI were at greater risk of presenting UTI (OR 4.05; 95% CI 2.65-6.18), followed by diabetes mellitus (OR 2.25; 95% CI 2.48-3.44), and overweight (OR 1.48; 95% CI 1.05-2.10). Regarding gestational age, the third trimester was a protective factor for UTI (OR 0.65; 95% CI 0.46-0.92]). Conclusions: The prevalence of UTI for pregnant women was 37.7%. The most frequent etiology was Escherichia coli. A history of UTI prior to pregnancy was the main risk factor.
Introducción: las infecciones de tracto urinario (ITU) son las más prevalentes en embarazadas. Existen factores de riesgo asociados que predisponen a la adquisición de una ITU en el embarazo, las cuales pueden causar complicaciones graves para la madre y el hijo. Objetivo: determinar la prevalencia de ITU y factores de riesgo asociados en mujeres embarazadas del Hospital Básico de Sangolquí. Material y métodos: estudio observacional, transversal, analítico realizado en 570 embarazadas del 1 de enero de 2021 al 30 de agosto de 2022. La prevalencia y los factores de riesgo asociados a ITU se analizaron con intervalos de confianza del 95% (IC 95%) y razones de momios (RM). Resultados: la prevalencia global de ITU en embarazadas fue de 37.7% (IC 95%: 33.7-41.7). La etiología más frecuente fue la Escherichia coli (65.4%), seguida por Staphylococcus spp. (21.8%). La edad de las mujeres gestantes osciló entre 12 y 45 años, promedio de 27.55 ± 7 años, de las cuales presentaron mayor riesgo de ITU aquellas con antecedentes de esta infección (RM 4.05; IC 95% 2.65-6.18), seguidas por aquellas con diabetes mellitus (RM 2.25; IC 95% 2.48-3.44) y sobrepeso (RM 1.48; IC 95% 1.05-2.10). En cuanto a la edad de gestación, el tercer trimestre fue un factor protector ante las ITU (RM 0.65; IC 95% 0.46-0.92). Conclusiones: la prevalencia de ITU de las gestantes fue de 37.7%. La Escherichia coli fue la etiología más frecuente. El antecedente de ITU previa al embarazo fue el principal factor de riesgo.

Introducción: El síndrome de la bolsa orina púrpura es una condición llamativa, que rara vez se presenta en la práctica clínica. Aparece en el contexto de infecciones urinarias en ancianos, pluripatológicos, con sonda vesical y factores de riesgo asociados. Se produce por una reacción química entre la orina, el material plástico de la bolsa colectora y enzimas sulfatasas/fosfatasas de bacterias que generan el color violáceo característico. Objetivo: Reportar un caso con síndrome de la bolsa orina púrpura, como forma de presentación inusual de infección urinaria. Caso Clínico: Paciente femenina, de 76 años de edad, con antecedentes de constipación habitual, acudió a urgencias por pérdida del conocimiento y hemiparesia derecha. Se realizó tomografía axial computarizada de cráneo y se diagnosticó una enfermedad cerebrovascular. Como parte de la conducta se indicó sonda vesical y 14 días después apareció orina de color violeta en la bolsa colectora. Se diagnosticó infección urinaria por Escherichia coli y se trató con ceftriaxona. Se normalizó el color de la orina al tercer día de tratamiento, la paciente evolucionó de forma favorable. Conclusiones: Aunque se puede identificar con facilidad, sin requerir exámenes costosos, constituye un reto para los médicos que atienden a pacientes geriátricos. Conocer este trastorno es fundamental, porque, aunque es infrecuente, puede ser la única manifestación de infección urinaria en pacientes con cateterismo uretral.
Introduction: Purple urine bag syndrome is a striking condition that rarely occurs in clinical practice. It appears in the context of urinary infections in the elderly, with multiple pathologies, with a bladder catheter and associated risk factors. It is produced by a chemical reaction between urine, the plastic material of the collection bag and sulfatase/phosphatase enzymes from bacteria that generate the characteristic purple color. Objective: To report a case with purple urine bag syndrome as an unusual presentation of urinary tract infection. Clinical Case: Female patient, 76 years old, health history, usual constipation, attended at Emergency due to loss of consciousness and right hemiparesis. Computed axial tomography of the skull was performed and a cerebrovascular disease was diagnosed. As part of the conduct, a bladder catheter was indicated and after 14 days, purple urine appeared in the collection bag. Urinary infection due to Escherichia coli was diagnosed and treated with ceftriaxone, normalizing the color of the urine on the third day of treatment, with patient favorable evolution. Conclusions: Although it can be easily identified and without requiring costly tests, it is a challenge for physicians who care for geriatric patients. Knowing this disorder is essential because, although rare, it may be the only manifestation of urinary infection in patients with urethral catheterization.
RESUMO
Una niña de 11 años de edad con antecedentes de ano imperforado, infección urinaria y episodios de constipación intermitentes se presentó a la consulta con cólicos abdominales y náuseas de una semana de evolución. Estudios radiológicos revelaron hidrometrocolpos y fusión renal pélvica con uréter único hidronefrótico. El examen vaginal evidenció un tabique transverso no permeable. Se evacuó temporalmente la colección con resolución de los síntomas. La paciente fue programada para cirugía vaginal reconstructiva definitiva. Se destaca en este caso no solo la asociación de malformaciones infrecuentes, sino una sintomatología muy común en la práctica pediátrica a causa de una patología rara vez considerada en el diagnóstico diferencial, y la importancia de una evaluación precoz y completa de este tipo de malformaciones para un tratamiento oportuno.
An 11-year-old girl with a history of imperforate anus, urinary tract infection, and intermittent episodes of constipation presented with abdominal pain and nausea for 1 week. The x-rays revealed hydrometrocolpos and fused pelvic kidney with a single hydronephrotic ureter. The vaginal examination revealed a non-permeable transverse vaginal septum. The collection was temporarily drained and symptoms resolved. The patient was scheduled for definitive vaginal reconstructive surgery. In this case, it is worth noting the association of infrequent malformations and also the signs and symptoms very common in pediatric practice due to a pathology rarely considered in the differential diagnosis, and the importance of an early and complete assessment of this type of malformations for a timely treatment.

Urinary tract infections (UTIs) are the most common infectious diseases worldwide. These infections are common in all people; however, they are more prevalent in women than in men. The main microorganism that causes 80-90% of UTIs is Escherichia coli. However, other bacteria such as Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, Proteus mirabilis, and Klebsiella pneumoniae cause UTIs, and antibiotics are required to treat them. However, UTI treatment can be complicated by antibiotic resistance and biofilm formation. Therefore, medicinal plants, such as spices generally added to foods, can be a therapeutic alternative due to the variety of phytochemicals such as polyphenols, saponins, alkaloids, and terpenes present in their extracts that exert antimicrobial activity. Essential oils extracted from spices have been used to demonstrate their antimicrobial efficacy against strains of pathogens isolated from UTI patients and their synergistic effect with antibiotics. This article summarizes relevant findings on the antimicrobial activity of cinnamon, clove, cumin, oregano, pepper, and rosemary, spices popularly used in Mexico against the uropathogens responsible for UTIs.
RESUMO
Introducción. La condición nutricional de la mujer antes y durante el embarazo es uno de los determinantes del riesgo de morbimortalidad materna. Objetivo. Determinar la relación del incremento del índice de masa corporal y la presencia de infección de las vías urinarias en primigestas. Métodos. Estudio de casos y controles en expedientes de primigestas. Se estudiaron variables sociodemográficas (edad, escolaridad, vida en pareja y ocupación), condiciones obstétricas (riesgo obstétrico, semanas de inicio del control prenatal, semanas de resolución del embarazo y número de consultas prenatales), antropometría al inicio y al final del embarazo (peso, talla, índice de masa corporal y condición nutricional -peso bajo, peso normal, sobrepeso y obesidad-, ganancia de peso y ganancia de índice de masa corporal) y modificación de la condición nutricional al inicio y al final del embarazo. El análisis estadístico se efectuó con porcentajes, promedios, intervalos de confianza para promedios, prueba de chi2, razón de momios, intervalos de confianza para razón de momios, regresión lineal simple y proyección de la ocurrencia del evento. Resultados. Cuando el incremento del índice de masa corporal fue de 5 kg/m2, el promedio de infección de las vías urinarias correspondió a 1,62 y, si el incremento del índice de masa corporal fue 10 kg/m2, el promedio de infección de las vías urinarias fue 2,3. Conclusión. En nuestro estudio, a mayor incremento del índice de masa corporal durante el embarazo de la primigesta, mayor fue su probabilidad de presentar infección de las vías urinarias.
Introduction: The nutritional status of women before and during pregnancy is one of the determinants of the risk of maternal morbidity and mortality. Objective: To determine the relationship between the increase in body mass index and the presence of urinary tract infection in primigravidae. Methods: Case-control study in primigravidae records. We studied sociodemographic variables (age, schooling, life as a couple and occupation), obstetric conditions (obstetric risk, weeks of beginning of prenatal control, weeks of pregnancy resolution and number of prenatal visits), anthropometry at the beginning and end of pregnancy (weight, height, body mass index and nutritional condition -underweight, normal weight, overweight and obesity-, weight gain and body mass index gain), and modification of nutritional condition at the beginning and end of pregnancy. Statistical analysis was performed with percentages, averages, confidence intervals for averages, Chi2 test, odds ratio, confidence intervals for odds ratio, simple linear regression, and projection of event occurrence. Results: When the increase in body mass index was 5 kg/m2, the mean urinary tract infection corresponded to 1.62 and, if the increase in body mass index was 10 kg/m2, the mean urinary tract infection was 2.3. Conclusion: In our study, the greater the increase in body mass index during pregnancy of the primigravida, the greater her probability of presenting urinary tract infection.
RESUMO
Resumen ANTECEDENTES: El mielomeningocele es el defecto del tubo neural más frecuente; se registra un caso por cada 1000 nacidos vivos. Es más frecuente en mujeres, que resultan con secuelas discapacitantes, entre ellas las urológicas. Pueden subsanarse con diferentes técnicas quirúrgicas y derivaciones urológicas complejas que las predispone a infecciones de vías urinarias de repetición y, cuando hay embarazo, complicaciones materno-fetales y dificultad para el acceso quirúrgico, en caso de cesárea. CASO CLÍNICO: Paciente con 14 semanas de embarazo, 27 años de edad, con diagnóstico de mielomeningocele y vesicoplastia, con múltiples infecciones urinarias y ruptura de membranas pretérmino. Finalización del embarazo por cesárea a las 33 semanas, por indicación de las condiciones fetales. La técnica de la cesárea se modificó para no dañar la cistoplastia y evitar complicaciones con las adherencias en la pelvis. CONCLUSIONES: El mejor pronóstico materno-fetal en pacientes con derivación urológica compleja se consigue con la búsqueda intencionada de infecciones urinarias y tratamiento oportuno y adecuado, además de una planificación multidisciplinaria al momento de la finalización del embarazo.
Abstract BACKGROUND: Myelomeningocele is the most common neural tube defect; one case per 1000 live births is reported. It is more frequent in females, resulting in disabling sequelae, including urological sequelae. They can be corrected with different surgical techniques and complex urological derivations that predispose them to repeated urinary tract infections and, when there is pregnancy, maternal-fetal complications and difficulty for surgical access, in case of cesarean section. CLINICAL CASE: Patient 14 weeks pregnant, 27 years old, diagnosed with myelomeningocele and vesicoplasty, with multiple urinary tract infections and preterm rupture of membranes. Termination of pregnancy by cesarean section at 33 weeks, due to fetal conditions. The cesarean section technique was modified so as not to damage the cystoplasty and to avoid complications with adhesions in the pelvis. CONCLUSIONS: The best maternal-fetal prognosis in patients with complex urologic diversion is achieved with the intentional search for urinary tract infections and timely and adequate treatment, in addition to multidisciplinary planning at the time of termination of pregnancy.
