Abstract
PURPOSE:We investigated the prevalence of asymptomatic bacteriuria and the incidence of symptomatic urinary tract infections in patients with neurogenic lower urinary tract dysfunction undergoing urodynamics. We also assessed predictors of symptomatic urinary tract infections. MATERIALS AND METHODS:We evaluated a prospective consecutive series of 317 patients, including 106 women and 211 men, with neurogenic lower urinary tract dysfunction. Of the patients 111 (35%) voided spontaneously, 141 (44%) relied on intermittent self-catheterization and 65 (21%) relied on an indwelling catheter. Before urodynamics the urine samples were collected by sterile catheterization for dipstick testing and urine culture. We assessed the association of patient characteristics with symptomatic urinary tract infections after urodynamics in patients with asymptomatic bacteriuria and developed a prediction model based on the most important risk factors. RESULTS:Before urodynamics urine cultures were negative in 123 patients (39%) and positive in 194 (61%). Escherichia coli and Klebsiella pneumoniae were the most frequent bacteria, found in 32% and 18% of patients, respectively. Of 194 patients with a positive culture 35 (18%) had at least 1 symptomatic urinary tract infection. In patients with a history of previous urinary tract infections the overall estimated probability of a symptomatic urinary tract infection was 45% regardless of the underlying neurological disorder. CONCLUSIONS:A symptomatic urinary tract infection will develop in the followup year in about 1 of 5 patients with asymptomatic bacteriuria. This rather low overall probability precludes routine antibiotic prophylaxis or treatment in patients with neurogenic lower urinary tract dysfunction who have asymptomatic bacteriuria since 4 of 5 would be overtreated. However, in patients with a history of previous symptomatic urinary tract infections antibiotic prescription might be justified.
摘要
目的: 我们调查了接受尿动力学检查的神经源性下尿路功能障碍患者中无症状性菌尿的患病率和症状性尿路感染的发生率。我们还评估了症状性尿路感染的预测因子。 材料和方法: 我们评估了 317 例神经源性下尿路功能障碍患者的前瞻性连续系列,包括 106 例女性和 211 例男性。111 例 (35%) 患者自发排尿,141 例 (44%) 依赖间歇自我导尿,65 例 (21%) 依赖留置导管。尿动力学检查前,采用无菌导尿法采集尿样进行试纸和尿培养。我们评估了无症状菌尿患者尿动力学后患者特征与症状性尿路感染的相关性,并基于最重要的危险因素开发了预测模型。 结果: 尿动力学检查前尿培养阴性 123 例 (39%),阳性 194 例 (61%)。大肠埃希菌和肺炎克雷伯菌是最常见的细菌,分别在 32% 和 18% 的患者中发现。在 1 94 例培养阳性的患者中,35 例 (1 8%) 至少有 1 例症状性尿路感染。在有既往尿路感染史的患者中,无论潜在的神经系统疾病如何,症状性尿路感染的总体估计概率为 45%。 结论: 5 例无症状性菌尿患者中,约 1 例在随访 1 年内出现症状性尿路感染。这种相当低的总体概率排除了神经源性下尿路功能障碍患者的常规抗生素预防或治疗,因为 5 例中有 4 例会过度治疗无症状菌尿。然而,对于既往有症状性尿路感染史的患者,抗生素处方可能是合理的。

METHODS:PURPOSE:In utero myelomeningocele closure is a valid alternative to postnatal repair with unclear benefits to bladder function. We compared bladder status in patients who underwent fetal myelomeningocele surgery versus postnatal repair. MATERIALS AND METHODS:We retrospectively reviewed our database, with group 1 consisting of in utero surgery and group 2 consisting of postnatal repair. Group 3 was a subgroup of group 2, including patients initially presenting at age less than 12 months. We recorded medical history, radiological investigation with renal ultrasonography, voiding cystourethrography, urodynamic evaluation and clinical outcome of the bladder pattern after treatment. RESULTS:We identified 88 patients in group 1, 86 in group 2 and 38 in group 3. The incidence of urinary tract infection was higher in the postnatal period (45% vs 20%). Hydronephrosis occurred in 20.7%, 22.6% and 28.9% of patients in groups 1, 2 and 3, respectively. Vesicoureteral reflux was diagnosed in 15% in all groups. Urodynamic data showed a higher prevalence of detrusor overactivity in group 1 and no difference in other urodynamic parameters. The high risk bladder pattern at initial evaluation occurred in 56%, 50% and 46% of patients in groups 1, 2 and 3, respectively. There was a trend to decrease the percentages of the high risk bladder pattern and to increase the normal pattern after treatment in all groups. CONCLUSIONS:In utero repair did not improve urological parameters compared to repair in the postnatal period.
METHODS::The development and evolution of antimicrobial resistance (AMR) in pathogens has been reported to be one of the major issues confronting the global health community. The aim of this study was to examine the period prevalence of antibiotic resistance, as well as the trends and patterns in sensitivity profile of enteric bacteria isolated from urine samples of patients with UTIs in a teaching Hospital in south west Nigeria. Urine samples were collected from 77 patients with UTIs from February 2017 to October 2018. Standard laboratory methods were used for urine sample culture and bacterial identification. The Kirby-Bauer disk diffusion method was used to evaluate antimicrobial sensitivity. Predominant enteric bacteria isolates were Escherichia coli (24, 39.3%), Salmonella species (12, 19.7%), Klebsiella species (4, 6.6%), Providencia species (6, 9.8%), Proteus species (8, 13.1%), Serratia species (2, 3.3%), Yersinia species (1, 1.6%) and Morganella species (4, 6.6%). A large proportion (90.2%) of isolates obtained were multi-drug resistant. High resistance in amoxycillin-clavulanate (98%), cefuroxime (92%), erythromycin (90%) and ceftazidime (84%) were recorded. These results emphasize the importance of continuous screening and surveillance programmes for detection of AMR in enteric bacteria of public health importance.
METHODS::Massive generation of health-related data has been key in enabling the big data science initiative to gain new insights in healthcare. Nursing can benefit from this era of big data science, as there is a growing need for new discoveries from large quantities of nursing data to provide evidence-based care. However, there are few nursing studies using big data analytics. The purpose of this article is to explain a knowledge discovery and data mining approach that was employed to discover knowledge about hospital-acquired catheter-associated urinary tract infections from multiple data sources, including electronic health records and nurse staffing data. Three different machine learning techniques are described: decision trees, logistic regression, and support vector machines. The decision tree model created rules to interpret relationships among associated factors of hospital-acquired catheter-associated urinary tract infections. The logistic regression model showed what factors were related to a higher risk of hospital-acquired catheter-associated urinary tract infections. The support vector machines model was included to compare performance with the other two interpretable models. This article introduces the examples of cutting-edge machine learning approaches that will advance secondary use of electronic health records and integration of multiple data sources as well as provide evidence necessary to guide nursing professionals in practice.
尿路感染又称泌尿系统感染,是尿路上皮对细菌侵入导致的炎症反应,通常伴随有菌尿和脓尿。尿路感染根据感染部位分为上尿路感染和下尿路感染。
