Resumen: 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.

Abstract: 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.

Resumo: Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas. Isso aumenta o risco de complicações relacionadas ao seu uso, portanto, podem ser evitáveis. 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 foi 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.

Abstract Background: Urinary tract infections (UTIs) are the second most common cause of graft dysfunction, accounting for significant morbidity, and are associated with poor graft and patient survival. This study aimed to assess the association between post-renal transplant UTI and graft outcomes. Methods: We examined the effect of UTIs on graft outcomes in patients who underwent renal transplantation surgery between January 2010 and December 2022. The study population included 349 renal transplantations, of which 74 experienced 140 UTI events. Based on the number of UTI episodes, patients were categorized into three groups. Results: Of the 349 recipients, 275 (74.4%) had no UTI, 47 (18.8%) had non-recurrent UTIs (NR-UTIs), and 27 (6.8%) had recurrent UTIs (R-UTIs). Kaplan-Meier survival analysis showed that post-KT UTI status was a significant factor in graft survival, death-censored graft survival, and patient survival after a follow up of 5 years (log rank, P < 0.001). R-UTIs were associated with very poor graft survival and patient survival when compared with no UTI after a follow up of 5 years (hazard ratio [HR], 1.506; 95% confidence interval [CI], 1.233–1.840; P < 0.001 & HR, 1.529; 95% CI, 1.227–1.905; P = 0.001). R-UTIs were more likely to be associated with multi-drug resistant Gram-negative organisms (Klebsiella pneumonia or Escherichia coli) with resistance to nitrofurantoin (RR, 2.753; 95% CI, 1.257–6.032; P = 0.01) and carbapenem (RR, 2.064; 95% CI, 0.988–4.314; P = 0.05). Conclusion: Compared to no UTI, R-UTIs were associated to worse graft and patient outcomes after a follow-up of 5 years, whereas NR-UTIs were associated with poor graft and patient outcomes in the long term.

Resumo Histórico: Infecções do trato urinário (ITU) são a segunda causa mais comum de disfunção do enxerto, responsáveis por morbidade significativa, sendo associadas à baixa sobrevida do enxerto e paciente. O objetivo deste estudo foi avaliar associação entre ITU pós-transplante renal e desfechos do enxerto. Métodos: Examinamos o efeito das ITU nos desfechos do enxerto em pacientes submetidos ao transplante renal entre janeiro/2010 e dezembro/2022. A população do estudo incluiu 349 transplantes renais, dos quais 74 apresentaram 140 eventos de ITU. Baseado no número de episódios de ITU, categorizamos os pacientes em três grupos. Resultados: Dos 349 receptores, 275 (74,4%) não apresentaram ITU, 47 (18,8%) apresentaram ITU não recorrentes (ITU-NR) e 27 (6,8%) apresentaram ITU recorrentes (ITU-R). O método de Kaplan-Meier mostrou que o status da ITU pós-TR foi um fator significativo na sobrevida do enxerto, sobrevida do enxerto censurada para óbito e sobrevida do paciente após acompanhamento de 5 anos (log rank, P < 0,001). ITU-R foram associadas à sobrevida muito baixa do enxerto e sobrevida do paciente comparadas com nenhuma ITU após acompanhamento de 5 anos (razão de risco [RR], 1,506; IC 95%, 1,233–1,840; P < 0,001 & RR, 1,529; IC 95%, 1,227–1,905; P = 0,001). ITU-R apresentaram maior probabilidade de serem associadas a organismos Gram-negativos multirresistentes (Klebsiella pneumonia ou Escherichia coli) resistentes à nitrofurantoína (RR, 2,753; IC 95%, 1,257–6,032; P = 0,01) e carbapenem (RR, 2,064; IC 95%, 0,988–4,314; P = 0,05). Conclusão: Em comparação com ausência de ITU, ITU-R foram associadas a piores desfechos do enxerto e paciente após acompanhamento de 5 anos, enquanto ITU-NR foram associadas a piores desfechos do enxerto e paciente em longo prazo.

Abstract Background: In institutionalized elderly people, urinary tract infections are the most common, involving 12% to 30% of this population, with at least one episode per year, where several risk factors influence their occurrence. Objective: To determine the prevalence of urinary tract infections in older people institutionalized in a private institution of social solidarity and to identify the risk factors. Methodology: This is a cross-sectional, observational, and epidemiological study conducted on a convenience sample of people who are institutionalized in a private institution of social solidarity and belong to three different services. Data was collected over 8 months, and the number of patients in the different services was recorded (n = 171). Results: The institution had a urinary tract infection prevalence of 18.1%. Although more cases occurred in women (p = 0.641) and people older than 75 years (p = 0.269), there were no significant differences. Location of hospitalization was identified as a risk factor for developing a urinary tract infection (p = 0.024). Conclusion: Out of the 171 people who were institutionalized, 31 developed a urinary tract infection. It is important to adopt educational and preventive measures.

Abstract: Urinary tract infections (UTIs) are one of the most frequent bacterial conditions in children, being enterobacteria the predominant etiologic agents. Streptococcus pneumoniae is an exceptional cause of UTI in the pediatric population. Objective: To report the case of a UTI caused by Streptococcus pneumoniae, and to discuss the need for urinary tract imaging studies based on a literature review. Clinical Case: A 2-year-old girl with megaureter and left hydronephrosis diagnosed in the context of a recurrent UTI, with poor adherence to prophylactic treatment, was hospitalized due to a new episode of febrile UTI without response to outpatient treatment with a broad-spectrum antibiotic. Streptococcus pneumoniae was isolated in the urine culture. She received parenteral therapy with ceftriaxone with good clinical course and, due to UTI caused by an atypical germ added to her history of renal malformation, prophylaxis was reinitiated and imaging studies were completed. Voiding cystourethrogram showed left grade V vesicoureteral reflux. Renal scintigraphy showed severe functional compromise of the left kidney, thus, surgical indication was considered. This case, along with 16 additional cases identified in a literature review, revealed that 12 of them (70%) showed concomitant renal-urological conditions. Conclusion: UTIs caused by Streptococcus pneumoniae are frequently associated with renal-urological alterations, which suggest the need to study the urinary tract in these patients.

Resumen: Las infecciones del tracto urinario (ITU) constituyen una de las afecciones bacterianas más frecuentes en pediatría, siendo las enterobacterias los agentes etiológicos predominantes. El Streptococcus pneumoniae es una causa excepcional de ITU en la población pediátrica. Objetivo: Comunicar un caso de ITU por Streptococcus pneumoniae, y discutir la necesidad de realizar estudios de imágenes de la vía urinaria en base a una revisión narrativa. Caso Clínico: Niña de 2 años portadora de megauréter e hidronefrosis izquierda diagnosticados en contexto de estudio de ITU recurrente, con poca adherencia al tratamiento profiláctico, que se hospitalizó por nuevo episodio de ITU febril sin respuesta a tratamiento ambulatorio con antibiótico de amplio espectro. En el urocultivo se aisló Streptococcus pneumoniae. La paciente fue tratada con ceftriaxona parenteral con buena evolución clínica y por el hallazgo del germen atípico sumado a su antecedente de malformación renal se reinició profilaxis y se completaron los estudios de imágenes. La cistouretrograña miccional mostró reflujo vesicoureteral izquierdo grado V. El centellograma renal mostró el riñón izquierdo con grave compromiso funcional, por lo que se planteó la indicación quirúrgica. El presente caso, junto a los 16 casos adicionales identificados en la revisión bibliográfica, reveló que 12 de ellos (70%) presentaban afecciones nefrourológicas concomitantes. Conclusión: Las ITUs por Streptococcus pneumoniae se asocian con alta frecuencia a alteraciones nefrourológicas, lo que sugiere la necesidad de estudiar la vía urinaria en estos pacientes.

RESUMEN Introducción: el lupus eritematoso sistémico (LES) se conoce como una enfermedad autoinmune multisistémica, cuya causa es desconocida, se caracteriza por la presencia de complejos inmunes y autoanticuerpos. En series internacionales se describe una presentación de procesos infecciosos en estos pacientes hasta en un 75 % de los casos, las infecciones ocurren tanto al inicio de la enfermedad como en etapas tardías, y son causa directa de muerte en 30 % a 60 % de los casos y motivo de hospitalización hasta de 30 %. Objetivos: determinar los procesos infecciosos más frecuentes en pacientes con lupus eritematoso sistémico internados en el Servicio de Clínica Médica del Hospital Nacional en el periodo 2022-2023. Metodología: diseño observacional, descriptivo de corte transversal de pacientes con diagnóstico de lupus eritematoso sistémico según criterios de European League Against Rheumatism (EULAR)-2019 que se encuentran internados en el servicio de Clínica Médica del Hospital Nacional (Itaugua-Paraguay) en el periodo de 2022-2023. Resultados: la edad media de los pacientes fue de 34 años, con predominio del sexo femenino en el 88.18 %. Las infecciones del aparato respiratorio fue la más frecuentemente diagnosticada en 50 (45.45 %) pacientes, seguido por la infección de vías urinarias 47 (42.38 %) pacientes, el condicionante de riesgo predominante fue el uso de corticoides en un total 105 (96.40 %) pacientes, se estableció en un total de 97 (88.18 %) pacientes con antibioticoterapia, dentro del aspecto demográfico de la zona urbana 56 (50.90 %) pacientes y rural 54(49.1 %). Conclusión: la infección del aparato respiratorio fue la infección más frecuente, el condicionante de riesgo predominante es el uso de corticoides y recibieron antibioticoterapia la cual en monoterapia fue la más utilizada

ABSTRACT Introduction: systemic lupus erythematosus (SLE) is known as a multisystem autoimmune disease, whose cause is unknown, and is characterized by the presence of immune complexes and autoantibodies. In international series, presentation of infectious processes is described in these patients in up to 75 % of cases. Infections occur both at the beginning of the disease and in late stages, and are a direct cause of death in 30 % to 60 % of patients. Cases and reason for hospitalization up to 30 %. Objectives: determine the most frequent infectious processes in patients with systemic lupus erythematosus admitted to the Medical Clinic Service of the Hospital Nacional in the period 2022-2023. Methodology: observational, descriptive cross-sectional design of patients with a diagnosis of systemic lupus erythematosus according to criteria of European League Against Rheumatism (EULAR)-2019 who are admitted to the Medical Clinic service of the Hospital Nacional (Itauguá-Paraguay) in the period of 2022-2023. Results: the average age of the patients was 34 years, with a predominance of the female sex in 88.18 %. Respiratory system infections were the most frequently diagnosed in 50 (45.45 %) patients, followed by urinary tract infection in 47 (42.38 %) patients. The predominant risk factor was the use of corticosteroids in a total of 105 (96.40 %) patients, it was established in a total of 97 (88.18 %) patients with antibiotic therapy, within the demographic aspect of the urban area 56 (50.90 %) patients and rural 54 (49.1 %). Conclusion: respiratory tract infection was the most frequent infection, the predominant risk factor is the use of corticosteroids and they received antibiotic therapy, which in monotherapy was the most used.

ABSTRACT Background: The constant increase of factors associated with the presence of resistant strains, makes empirical antibiotic selection a challenge in patients hospitalized for community-acquired urinary tract infection. Aim: We characterized the bacteria and their antimicrobial susceptibility pattern in cultures obtained from adult patients that needed hospitalization for this disease in two tertiary hospitals in Santiago, Chile. Methods: We conducted a prospective cross-sectional study in adults hospitalized for community-acquired urinary tract infection between 2017 and 2022. All patients with positive urine cultures were included in the analysis. Results: A total of 830 patients were included. Escherichia coli was the most frequent infectious agent (68.1%), followed by Klebsiella spp. (17.7%) and Enterococcus faecalis (6.7%). Among Enterobacteriaceae strains, 35.2%, 19.7% and 27.2% were resistant to first, second and third-generation cephalosporin, respectively. 36.9% were resistant to ciprofloxacin and 1.8% to amikacin. Gram-positive bacteria were resistant to oxacillin and ampicillin in 25% and 18%, respectively. Conclusion: We detected a high prevalence of community-acquired urinary tract infections caused by bacteria resistant to commonly used antibiotics in adult patients that need to be hospitalized.

RESUMEN El constante aumento de factores asociados a la presencia de cepas resistentes en pacientes hospitalizados por infección del tracto urinario adquirida en la comunidad (ITU-AC), hace que la selección empírica de antibióticos sea un desafío. Objetivo: caracterizar el tipo de bacterias y su patrón de susceptibilidad antimicrobiana, en cultivos obtenidos de pacientes adultos que requirieron hospitalización por ITU-AC en dos hospitales terciarios de Santiago, Chile. Material y Método: Se realizó un estudio de corte transversal prospectivo en adultos hospitalizados por ITU-AC entre los años 2017 y 2022. Todos los pacientes con urocultivos positivos fueron incluidos en el análisis. Resultados: Se incluyeron un total de 830 pacientes. Escherichia coli fue el agente infeccioso más frecuente (68.1%), seguido por Klebsiella spp. (17.7%) y Enterococcus faecalis (6.7%). Entre las cepas de Enterobacteriaceae, el 35.2%, el 19.7% y el 27.2% fueron resistentes a cefalosporinas de primera, segunda y tercera generación, respectivamente. El 36.9% fue resistente a ciprofloxacino. Sólo el 1.8% fue resistente a amikacina. Las bacterias Gram positivas fueron resistentes a oxacilina y ampicilina en un 25% y un 18%, respectivamente. Conclusión: Se detectó una alta prevalencia de ITU-AC causadas por bacterias resistentes a antibióticos comúnmente utilizados en pacientes adultos que necesitan hospitalización.

Resumo Introdução: Os inibidores do co-transportador de sódio-glicose 2 (iSGLT2) são fármacos cada vez mais utilizados no tratamento da diabetes mellitus tipo 2 (DM2) por apresentarem benefícios em doentes com comorbilidades como doença renal crónica e insuficiência cardíaca. Existe evidência que suporta a relação entre a terapêutica com iSGLT2 e o aumento do risco de infeções genitais. Em relação à sua associação com infeções do trato urinário (ITU) existem algumas incongruências na literatura. Objetivos: Avaliar se os utentes com DM2 medicados com iSGLT2 estão em risco aumentado de terem ITU e infeções genitais, numa amostra de doentes com DM2 seguidos numa Unidade de Saúde e Familiar (USF), em comparação com utentes sob terapêutica com outros grupos farmacológicos de antidiabéticos, que não os iSGLT2. Métodos: Estudo caso-controlo, com uma população com DM2 inscritos numa USF do Norte de Portugal. Foram comparados os registos, do ano de 2021, de ocorrência de cistite, pielonefrite/ pielite, balanite, prostatite, vaginite, candidíases e tricomoníase em utentes medicados com iSGLT2 com um grupo não medicado com estes fármacos (variável grupo: caso ou com iSGLT2 vs controlo ou sem iSGLT2). Foram efetuados modelos de regressão logística (simples e múltiplos) de forma a estudar a associação entre a terapêutica com iSGLT2 e as infeções mencionadas. Resultados: Amostra final: 953 utentes. Para a ocorrência de cistite, o grupo iSGLT2 mostrou-se protetor para este outcome, com um OR de 0,47 [0,24; 0,90]. Quando a variável grupo foi ajustada para os fatores de risco potencialmente confundidores perdeu a significância no modelo final 0,54 [0,27; 1,07]. Para o desenvolvimento de pielonefrite, balanite, vaginite e tricomoníase, a variável grupo não se mostrou significativamente associada. Conclusão: Este estudo parece favorecer a segurança a nível de infeções urinárias e genitais na utilização dos iSGLT2 que possam limitar a prescrição destes fármacos.

Abstract Introduction: Sodium-glucose co-transporter 2 inhibitor (iSGLT2) drugs are being increasingly used in type 2 diabetes mellitus (DM2), due to their benefit in chronic kidney disease and heart failure - frequent comorbidities in patients with DM2. Evidence has been found linking iSGLT2 usage to an increased risk of genital infections. Regarding iSGLT2’s association with urinary tract infections (UTI), the findings are inconsistent. Aim: Determine in a sample taken from a primary care center, to determine whether DM2 patients treated with iSGLT2 are at an increased risk of UTI and genital infections when compared to DM2 patients treated only with other antidiabetic drugs. Methods: A case-control study, of a population of DM2 patients from a primary care center in the north of Portugal. Records from the year 2021 of cystitis, pyelonephritis/pyelitis, balanitis, prostatitis, vaginitis, candidiasis, and trichomoniasis, of iSGLT2 medicated DM2 patients were compared to those without this treatment (group variable: case with iSGLT2 vs control without iSGLT2). Logistic regression models were utilized to derive the association between iSGLT2 usage and previously mentioned infections. Results: Final sample: 953 patients. The group iSGLT2 was protective of the outcome cystitis, with an OR=0.47 [0.24; 0.90]. After adjusting for potential confounding factors this association was no longer significant - OR=0.54 [0.27; 1.07]. There was no significant association found between iSGLT2 usage and pyelonephritis/pyelitis, balanitis, prostatitis, vaginitis, candidiasis, and trichomoniasis. Conclusion: The present study seems to favor iSGLT2 safety regarding urinary and genital infections that may limit the prescription of these drugs.

Abstract 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.

Conclusiones: Tamaño de divertículos vesicales es factor significativo en presentación clínica, manejo de divertículos vesicales primarios en pacientes pediátricos.

SUMMARY OBJECTIVE: This study was designed to determine the effect of cranberry extract used in patients with single urinary tract infections. METHODS: Patients with simple-type urinary tract infections were divided into two groups. Treatment with fosfomycin or cranberry tablet was started. On days 1, 3, and 7 of the treatment, whether there was a decrease in the complaints was evaluated with a Likert-type scale. The recovery status of urinary tract infections and the well-being of patients were compared via antibiotic and cranberry groups. RESULTS: After the treatment, the leukocyte levels of the cranberry users were at the same level as those of the other group, and the rate of well-being and the portion of patients that reported to be “very well” on days 3 and 7 in the cranberry group was significantly higher compared with the fosfomycin group (p<0.05). CONCLUSION: Considering the results of this study, it was determined that the patient's complaints decreased from day 3 and their well-being increased with the use of cranberry only. Specifically, on day 7, the well-being of the cranberry group was higher than that of the fosfomycin group. For this reason, cranberry is a favorable alternative to antibiotics in uncomplicated and simple urinary tract infections.

Abstract Objectives To compare the efficacy and safety of larotrectinib with those of infigratinib in adult glioma patients with tyrosine kinase alterations. Methods Patients received oral infigratinib 125 mg (IN cohort, n = 125) or oral larotrectinib (LB cohort, n = 105) until unacceptable toxicity or disease progression. Results Duration of treatment was longer in the LB cohort than in the IN cohort (8 [9.5-6.25] months vs. 5.5 [6-5.25] months, p < 0.0001). Patients with partial responses (p = 0.0424) and overall survival (p = 0.03) were higher in the IN cohort than those in the LB cohort. The number of patients with disease progression was higher in the LB cohort (p = 0.0015). All the patients reported diarrhea, fatigue, vomiting, constipation, and decreased appetite. Patients in the IN cohort reported hyperphosphatemia, hyperlipasemia, stomatitis, dry skin, alopecia, dyspepsia, onycholysis, palmar-plantar erythrodysesthesia, nail disorders, and dry eyes. Patients in the LB cohort reported upper respiratory tract infections, pyrexia, cough, anemia, bacterial/viral infections, conjunctivitis, urinary tract infections, headaches, ataxia, dizziness, and muscle tremors. A total of 30 (24 %) and 40 (38 %) patients from the IN and the LB cohorts died at the follow-up of 18 months (p = 0.03). Patients who received bevacizumab initial therapy had higher overall survival (p = 0.048). Conclusions Infigratinib has higher efficacy and overall survival than larotrectinib but has higher adverse effects in the management of both glioma and tyrosine kinase alterations after failure of initial therapies. Initial bevacizumab therapy is associated with a higher overall survival. 12 105 8 ( 9.56.25 95625 9.5 6.25 9 5 6 25 [9.5-6.25 vs 55 5. 65.25 6525 5.25 [6-5.25 0.0001. 00001 0.0001 . 0 0001 0.0001) 0.0424 00424 0424 0.03 003 03 0.0015. 00015 0.0015 0015 0.0015) diarrhea fatigue vomiting constipation appetite hyperphosphatemia hyperlipasemia stomatitis skin alopecia dyspepsia onycholysis palmarplantar palmar plantar erythrodysesthesia disorders eyes infections pyrexia cough anemia bacterialviral bacterial viral conjunctivitis headaches ataxia dizziness tremors 3 24 (2 % 4 38 (3 followup follow up 1 0.03. 0.048. 0048 0.048 048 0.048) therapies 10 56 9.56.2 9562 95 9. 625 6.2 2 [9.5-6.2 65 65.2 652 525 5.2 [6-5.2 0000 0.000 000 0.042 0042 042 0.0 00 0.001 001 004 0.04 04 9.56. 956 62 6.

Schinus terebinthifolius Raddi (Anacardiaceae), commonly known as “pimenta rosa”, “aroeira da praia”, “aroeira”, “aroeirinha”, and “cabuí” is frequently used in traditional medicine to address various conditions, including skin wounds, ulcers, tumors, diarrhea, arthritis, as well as urinary and respiratory tract infections. This study aimed to develop and validate an analytical method using high-performance liquid chromatography with diode array detector (HPLC-DAD) for quantifying gallic acid (GA) in methanolic extracts of S. terebinthifolius leaves, branches, and fruits. The chromatographic separations utilized a reversed-phase Zorbax Eclipse XDB-C18 column with an isocratic elution mode of acetonitrile/methanol/water acidified with 0.2% formic acid. The flow rate was 0.8 mL min-1, and detection occurred at 254 nm. The developed HPLC-DAD method demonstrated selectivity, with a GA retention time of 5.263 min and absorption maxima at 220 and 271 nm. The method exhibited high linearity (coefficient of 0.9996), precision (relative standard deviation (RSD) values < 5%), and robustness. Accuracy ranged from 100.28 to 111.71%, with an average recovery of 105.41% and an average RSD of 3.46%. These validated results play a crucial role in assessing and standardizing raw materials containing S. terebinthifolius, emphasizing the reliability of the developed HPLC-DAD method for GA quantification in different plant parts.

ABSTRACT Endophthalmitis is a severe form of purulent inflammation caused by the infection of the intraocular tissues or fluids. This infection infrequently occurs through endogenous routes, which are often correlated with major risk factors. Escherichia coli, a gram-negative rod, can cause endophthalmitis through hematogenous spread. We here report a 59-year-old man who presented to our service with acute visual impairment in his left eye, preceded by floaters. He was taking sirolimus and azathioprine for a transplanted kidney, had undergone catheterization for bladder atresia, and had a history of recurrent E. coli urinary tract infections. On evaluation, the left eye exhibited visual acuity of hand motion, anterior chamber reaction (3+/4+), and intense vitritis (4+/4+) with white flake clusters, which prevented appropriate retinal evaluation. Pars plana vitrectomy was performed, and the culture yielded E. coli. The present case highlights the importance of identifying the signs and symptoms of infection early so that diagnosis and treatment of endophthalmitis can be promptly initiated. fluids routes factors gramnegative gram negative rod spread 59yearold yearold 59 year old floaters kidney atresia E infections evaluation motion 3+/4+, 34 3+/4+ , 3 4 (3+/4+) 4+/4+ 44 (4+/4+ clusters performed initiated 5 3+/4 (3+/4+ 4+/4 (4+/4 3+/ (3+/4 4+/ (4+/ 3+ (3+/ 4+ (4+ (3+ (4 (3 (

ABSTRACT Introduction: Considering the rising occurrence of posttranplant diabetes and the elevated cardiovascular burden among transplant recipients, the utilization of SGLT2 inhibitors (SGLT2i) in this group is appealing because of their cardiovascular and renoprotective benefits. Nevertheless, there is a scarcity of evidence for diabetic kidney transplant recipients (DKTRs) owing to concerns about potential renal graft damage and adverse effects. Methods: This retrospective study was devised to assess the effectiveness and safety of SGLT2i in kidney transplant recipients (KTRs). The main focus was on evaluating their impact on parameters such as haemoglobin A1c levels, body mass index (BMI), lipid panel, haemoglobin levels, renal allograft function (estimated glomerular filtration rate) and urirnary protein-to-creatinine ratio. Results: A total of 75 renal transplant patients were included in this investigation. The study spanned a median observation period of 18 (2.0–71.0) months. Median estimated glomerular filtration rate at baseline was 61,9 (26–120) mL/min/1.73 m2 and remained stable throughout the follow-up. Median HbA1cdecreased from 7.5 to 7.0% (95% CI; p<0,002). A significant improvement in BMI (95% CI; p<0,001) and lipid panel (95% CI; p<0,05) were also observed. Median haemoglobin rate at baseline was 13,5g/dL and modestly improved at end of follow-up to 13,7g/dL (p=0,12). Regarding urinary protein:creatinine ratio, levels slightly but not significantly rose [+0.05 g/g (p=0,9)]. In a post-hoc subgroup analysis, the rate of urinary tract infections was low (10%). No other side effects were observed during the treatment course. Conclusions: This study demonstrates that the administration of SGLT2i is viable and well-tolerated, with no notable side effects observed in KTRs. However, the question of whether SGLT2i can effectively lower cardiovascular mortality and enhance allograft survival in these patients remains to be explored in subsequent studies.

RESUMO Introdução: Considerando o aumento da incidência de diabetes pós-transplante e o elevado impacto cardiovascular entre os receptores de transplantes, este facto faz com que o uso de inibidores de SGLT2 nesse grupo seja atrativo devido aos seus benefícios cardiovasculares e renoprotetores. No entanto, há escassez de evidência nos receptores de transplante renal com diabetes devido a preocupações com possíveis danos ao enxerto renal e efeitos adversos. Métodos: Este estudo retrospectivo foi elaborado para avaliar a eficácia e segurança dos inibidores de SGLT2 em receptores de transplante renal (KTRs). O foco principal foi avaliar o seu impacto em parâmetros como níveis de hemoglobina A1c, índice de massa corporal (IMC), perfil lipídico, níveis de hemoglobina, função do enxerto renal (taxa de filtração glomerular estimada) e relação proteína/creatinina urinária. Resultados: Um total de 75 pacientes receptores de transplante renal foram incluídos em nossa investigação. O estudo abrangeu um período de observação mediano de 18 (2,0–71,0) meses. A taxa média de filtração glomerular estimada no início foi de 61,9 (26–120) mL/min/1,73 m2 e permaneceu estável durante o acompanhamento. A mediana da HbA1c diminuiu de 7,5 para 7,0% (IC 95%; p<0,002). A melhora significativa no IMC (IC 95%; p<0,001) e no perfil lipídico (IC 95%; p<0,05) também foram observados. A taxa média de hemoglobina no início foi de 13,5g/dL e melhorou modestamente no final do acompanhamento para 13,7g/dL (p=0,12). Em relação à relação proteína/creatinina urinária, os níveis aumentaram ligeiramente, mas não significativamente [+0,05 g/g (p=0,9)]. Numa análise de subgrupo post-hoc, a taxa de infecções do trato urinário foi baixa (10%). Nenhum outro efeito colateral foi observado durante o curso do tratamento. Conclusões: Este estudo demonstra que a administração de inibidores de SGLT2 é viável e bem tolerada, sem efeitos colaterais notáveis em receptores de transplante renal. No entanto, a questão de saber se a inibição do SGLT2 pode efetivamente reduzir a mortalidade cardiovascular e melhorar a sobrevida do enxerto nesses pacientes permanece a ser explorada em estudos subsequentes.

ABSTRACT Lower urinary tract abnormalities are directly implicated in the etiology of renal dysfunction in 6 to 24% of dialytic patients. These patients require bladder capacity and compliance readjustment before being considered viable candidates for renal transplantation. Vesical augmentation surgeries often involve the use of intestinal segments. Although these procedures can effectively restore bladder capacity and compliance, they present various issues related to maintaining mucous absorption and secretion capacity. Acidosis, recurrent urinary tract infections, and stone formation are extremely common, leading to frequent hospitalizations and graft function loss. Urinary tissue is certainly ideal for these reconstructions; however, bladder augmentation using ureter and renal pelvis are feasible only in a minority of cases. Experimental studies have been conducted to establish the groundwork for vascularized bladder transplantation. Last year, for the first time, this procedure was performed on a brain-dead patient. During this intervention, cystectomy was performed with preservation the vascular pedicle, followed by organ reimplantation. The graft remained viable for a period of 12 hours post-transplant. However, this intervention utilized a robotic platform, making it less reproducible in a multi-organ procurement setting as well as for most transplant centers. Moreover, it is debatable whether the benefits of exclusive bladder transplantation outweigh the risks associated with immunosuppression. For patients needing renal transplantation and requiring lower urinary tract reconstruction, however, utilizing the donor’s bladder may offer an attractive alternative, avoiding the inherent complications of enterocystoplasty without increasing immunological risk. Combined kidney and bladder transplantation has the potential to emerge as the next frontier in abdominal organ transplants. 24 segments Acidosis infections common loss reconstructions however cases year time braindead brain dead patient pedicle reimplantation 1 posttransplant. posttransplant post transplant. post-transplant However platform multiorgan multi centers Moreover immunosuppression reconstruction donors donor s alternative risk transplants 2

RESUMO As alterações do trato urinário inferior estão diretamente implicadas na etiologia da disfunção renal em 6 a 24% dos pacientes em diálise. Esses pacientes necessitam readequação da capacidade e complacência vesical antes de serem considerados candidatos viáveis para o transplante renal. As cirurgias de ampliação vesical frequentemente envolvem a utilização de segmentos intestinais. Embora estes procedimentos possam reestabelecer de forma eficaz a capacidade e complacência vesical, apresentam diversos problemas relacionados à manutenção da capacidade de absorção e secreção de muco. Acidose, infecções urinárias de repetição e formação de cálculos são extremamente comuns levando a internações frequentes e perda de função do enxerto. O tecido urinário é certamente ideal para estas reconstruções, contudo, ampliações vesicais utilizando ureter e pelve renal são viáveis somente em uma minoria dos casos. Estudos experimentais têm sido conduzidos na busca de se estabelecer os fundamentos para um transplante vascularizado de bexiga. No ano passado, pela primeira vez, este procedimento foi realizado em um paciente em morte encefálica. Nessa intervenção, foi realizada a cistectomia, preservando-se o pedículo vascular, seguida pelo reimplante do órgão. Esse enxerto mostrou-se viável pelo período de 12 horas após o transplante. Entretanto, nesta intervenção, foi utilizada plataforma robótica tornando-o pouco reprodutível em um contexto de captação de múltiplos órgãos bem como para a maioria dos centros transplantadores. Além disso, é discutível se os benefícios do transplante vesical exclusivo compensam os riscos associados à imunossupressão. Para pacientes que precisam ser submetidos a transplante renal e requerem reconstrução do trato urinário inferior, entretanto, a utilização da bexiga do mesmo doador pode representar uma alternativa atraente, evitando as complicações inerentes às enterocistoplastias sem aumento do risco imunológico. O transplante combinado de rim e bexiga tem o potencial de se destacar como a próxima fronteira nos transplantes de órgãos abdominais. 24 diálise intestinais muco Acidose reconstruções contudo casos passado vez encefálica intervenção cistectomia preservandose preservando vascular órgão mostrouse mostrou 1 Entretanto tornandoo tornando transplantadores disso imunossupressão entretanto atraente imunológico abdominais 2
