Neonatal jaundice is associated with increased risks of congenital anomalies of the kidney and urinary tract and concomitant urinary tract infection.

The link between neonatal jaundice and urinary tract infection (UTI) remains debated, with congenital kidney and urinary tract anomalies (CAKUT) potentially playing a role. This population-based study aimed to analyze the correlations between neonatal jaundice, CAKUT, and concomitant UTI. The study cohort consisted of 2,078,122 live births from 2004 to 2014. We linked several population-based datasets in Taiwan to identify infants with unexplained neonatal jaundice and their mothers. The primary outcome was the rate of CAKUT occurring within 3 years after delivery, and the presence of concomitant UTI during neonatal jaundice hospitalization. Infants with neonatal jaundice had a significantly higher risk of CAKUT (adjusted odds ratio [aOR] 1.24, 95% confidence interval [CI] 1.11-1.39) during early childhood. Among the subtypes of CAKUT, obstructive uropathy, vesicoureteral reflux and other CAKUT were associated with an increased risk of neonatal jaundice. Infants who underwent intensive phototherapy, had a late diagnosis (> 14 days of postnatal age) or underwent a prolonged duration of phototherapy (> 3 days) exhibited a higher risk of concomitant UTI compared to other infants with jaundice. Our findings indicate a notable association between neonatal jaundice and increased risks of UTIs in the context of CAKUT. This study underscore the importance of vigilant monitoring and timely interventions for neonates presenting with jaundice, while acknowledging the complexity and variability in the progression of CAKUT and its potential connection to UTIs.

Evaluation of urinary tract infections in neonatal indirect hyperbilirubinemia.

BACKGROUND: We have evaluated urinary tract infections (UTI) in neonatal indirect hyperbilirubinemia. Urine culture is not routinely requested in patients with indirect hyperbilirubinemia. However, debates continue about the frequency and investigation of UTI in neonatal indirect hyperbilirubinemia patients. The aim of this study was to determine the prevalence of UTI in neonates admitted to the hospital due to pathological indirect hyperbilirubinemia and whether a routine urine culture test is necessary in patients. METHODS: In this retrospective study, we analyzed data from 1390 patients hospitalized to the Neonatal Unit due to pathological indirect hyperbilirubinemia. One hundred and eleven of these patients with detected bacterial agents in the urine cultures were evaluated. The type of the pathogens grown in urine culture, the number of colonies, and the antibiotic resistance status were evaluated. RESULTS: Among 1390 patients screened, 111 (8%) were found to have UTI, 68 of whom (61.3%) were male. Out of the microorganisms that grew, Escherichia coli was the dominant microorganism with 36.1%, which was followed by Klebsiella species (23.4%), and Enterococcus species (18%), respectively. CONCLUSIONS: The prevalence of UTI is high in the neonatal period as in all childhood and especially in patients admitted to the Neonatal Unit due to indirect hyperbilirubinemia. Escherichia coli and Klebsiella species are the most common bacterial agents that grow. Missing the diagnosis of urinary tract infection in neonates may cause renal problems. Therefore, we recommend requesting a urine culture in routine examinations of neonates who are diagnosed with pathological indirect hyperbilirubinemia and admitted to the hospital due to the need for phototherapy.

Resistência antimicrobiana na infecção urinária em unidade de terapia intensiva / Antimicrobial resistance in urinary tract infection in the intensive care unit / Resistencia a los antimicrobianos en la infección del tracto urinario en la unidad de cuidados intensivos

A infecção do trato urinário (ITU) nada mais é do que o acometimento das vias urinárias por microrganismo. Entre as infecções hospitalares de maior incidência está a infecção do trato urinário, acometendo mais mulheres do que homens. Uma das possíveis causas dessa infecção, em pacientes na unidade de terapia intensiva (UTI), é o uso de cateter vesical. Seu tratamento inadequado pode ocasionar uma pielonefrite, podendo adentrar à circulação sanguínea, gerando uma infecção sistêmica e levar o paciente a óbito. A resistência antimicrobiana é uma das principais dificuldades encontrada em UTI sendo considerado um problema de saúde pública. O objetivo deste trabalho foi realizar um breve relato, baseado na literatura, sobre a resistência antimicrobiana na infecção urinária em unidade de terapia intensiva adulta. Em ambientes hospitalares o principal microrganismo causador de ITU é Escherichia coli, sendo 55,5% das culturas positivas estão associadas a procedimentos invasivos, como as sondas vesicais de demora, como consequência este é o microrganismo que mais apresenta resistência aos antimicrobianos utilizados como a ampicilina, trimetoprima e ciprofloxacino. O uso indiscriminado de antibióticos deixa em evidência a necessidade de análise criteriosa da real necessidade de qual antimicrobianos usar, tempo de uso e forma correta de administração. Portanto é necessária a ação dos profissionais de saúde frente a atenção ao paciente, desde a higiene das mãos, uso do cateter, quando necessário observar a real necessidade do uso do antimicrobianos e que esse seja feito após cultura e antibiograma.

Urinary tract infection (UTI) is nothing more than the involvement of the urinary tract by a microorganism. Among the hospital infections with the highest incidence is urinary tract infections, affecting more women than men. One of the possible causes of this infection in patients in the intensive care unit (ICU) is the use of a bladder catheter. Its inadequate treatment can cause pyelonephritis, which can enter the bloodstream, generating a systemic infection and leading the patient to death. Antimicrobial resistance is one of the main difficulties encountered in ICUs and is considered a public health problem. The objective of this study was to present a brief report, based on the literature, on antimicrobial resistance in urinary tract infections in an adult intensive care unit. In hospital environments, the main microorganism that causes UTI is Escherichia coli, and 55.5% of positive cultures are associated with invasive procedures, such as indwelling urinary catheters, as a consequence, this is the microorganism that is most resistant to antimicrobials used, such as ampicillin, trimethoprim and ciprofloxacin. The indiscriminate use of antibiotics highlights the need for a careful analysis of the real need for which antimicrobials to use, time of use, and correct form of administration. Therefore, it is necessary for the action of health professionals in the care of the patient, from the hygiene of the professional to, the use of the catheter, when necessary to observe the real need for the use of antimicrobials and that this is done after culture and antibiogram.

La infección del tracto urinario (ITU) no es más que la afectación de las vías urinarias por un microorganismo. Entre las infecciones hospitalarias con mayor incidencia se encuentra la infección del tracto urinario, que afecta más a mujeres que a hombres. Una de las posibles causas de esta infección en pacientes en la unidad de cuidados intensivos (UCI) es el uso de una sonda vesical. Su tratamiento inadecuado puede causar pielonefritis, la cual puede ingresar al torrente sanguíneo, generando una infección sistémica y llevando al paciente a la muerte. La resistencia a los antimicrobianos es una de las principales dificultades encontradas en las UCI y se considera un problema de salud pública. El objetivo de este estudio fue presentar un breve informe, basado en la literatura, sobre la resistencia antimicrobiana en infecciones del tracto urinario en una unidad de cuidados intensivos de adultos. En ambientes hospitalarios, el principal microorganismo causante de ITU es Escherichia coli, y el 55,5% de los cultivos positivos están asociados a procedimientos invasivos, como sondas vesicales permanentes, por lo que este es el microorganismo más resistente a los antimicrobianos utilizados, como la ampicilina. ., trimetoprima y ciprofloxacino. El uso indiscriminado de antibióticos pone de relieve la necesidad de un análisis cuidadoso de la necesidad real de qué antimicrobianos utilizar, el momento de uso y la forma correcta de administración. Por lo tanto, es necesaria la actuación de los profesionales de la salud en el cuidado del paciente, desde la higiene del profesional, uso del catéter, cuando sea necesario observar la necesidad real del uso de antimicrobianos y que este se realice previo cultivo y antibiograma.

Distal renal tubular acidosis presenting with an acute hypokalemic paralysis in an older child with severe vesicoureteral reflux and syringomyelia: a case report.

BACKGROUND: Distal renal tubular acidosis (dRTA) is the most common type of renal tubular acidosis (RTA) in children. Pediatric dRTA is usually genetic and rarely occurs due to acquired issues such as obstructive uropathies, recurrent urinary tract infections (UTIs), and chronic kidney disease (CKD). Although persistent hypokalemia frequently occurs with dRTA, acute hypokalemic paralysis is not frequently reported, especially in older children. CASE PRESENTATION: An eight-year-old girl presented with an acute first episode of paralysis. A physical examination revealed normal vital signs, short stature consistent with her genetic potential, and decreased muscle strength of her upper and lower extremities. Preexisting conditions included stage 4 CKD due to recurrent UTIs, severe vesicoureteral reflux and bilateral hydronephrosis, neurogenic bladder, and multisegment thoracic syringomyelia. Her laboratory work-up revealed hypokalemic, hyperchloremic metabolic acidosis with a normal anion gap. She also had a urine osmolal gap of 1.9 mOsmol/kg with a high urine pH. Intravenous potassium replacement resulted in a complete resolution of her paralysis. She was diagnosed with dRTA and discharged with oral bicarbonate and slow-release potassium supplementation. CONCLUSIONS: This case report highlights the importance of considering dRTA in the differential diagnosis of hypokalemic acute paralysis in children. Additionally, in children with neurogenic lower urinary tract dysfunction and recurrent UTIs, early diagnosis of spinal cord etiology is crucial to treat promptly, slow the progression of CKD, and prevent long-term complications such as RTA.

Clinical effectiveness of beta-lactams versus fluoroquinolones as empirical therapy in patients with diabetes mellitus hospitalized for urinary tract infections: A retrospective cohort study.

BACKGROUND: Diabetic patients are at risk of severe urinary tract infections (UTIs). Due to the emerging resistance rates to fluoroquinolones and ß-lactams, we aimed to evaluate the effectiveness of ß-lactams versus fluoroquinolones as empirical therapy for diabetic patients hospitalized for UTIs. METHODS: A retrospective cohort study was conducted in a medical center in Taiwan between 2016 and 2018. Patients with type 2 diabetes, aged ≥20 and hospitalized for UTIs were enrolled. Patients with UTI diagnosis within one year before the admission, co-infections at the admission, or ≥2 pathogens in the urine cultures were excluded. The primary outcome was empiric treatment failure. RESULTS: 298 patients were followed for at least 30 days after the admission. Escherichia coli (61.07%) was the most common pathogen. The resistance rates of the pathogens to levofloxacin were 28.52% and 34.22% according to the historical Clinical and Laboratory Standards Institute (CLSI) breakpoints and the updated 2019 CLSI breakpoints, respectively. The resistance rates of ceftazidime and cefepime were 21.81% and 11.41%, respectively. Empirical ß-lactams were associated with less treatment failure compared to fluoroquinolones (adjusted OR = 0.32, 95% CI = 0.17-0.60). Beta-lactams were associated with less treatment failure than fluoroquinolones when appropriatness was determined by the pre-2019 CLSI breakpoints but not the 2019 CLSI breakpoints. CONCLUSIONS: In diabetic patients hospitalized for UTIs, ß-lactams were associated with less empiric treatment failure compared to fluoroquinolones when the resistance rate to fluoroquinolone is higher than ß-lactams. The updated 2019 CLSI breakpoint for fluoroquinolone was better than pre-2019 CLSI breakpoints to correlate with treatment outcomes for hospitalized UTIs in diabetic patients.

The change of antibiotic susceptibility in febrile urinary tract infection in childhood and adolescence during the last decade.

PURPOSE: The purpose of this study was to clarify the pattern of antibiotic resistance in pediatric urinary tract infections (UTIs). MATERIALS AND METHODS: We analyzed the data of entire urine culture tests and antibiotic susceptibility tests performed on hospitalized patients for febrile UTI at the Uijeongbu St. Mary's Hospital during 2010-2020. A retrospective analysis was performed using medical records of urine culture results and antibiotic susceptibility results in patients with UTIs. RESULTS: We performed urine cultures from 2,491 patients, and identified bacterial types in 1,651 cases. We found that the resistance rates to ampicillin, ampicillin/sulbactam, cefazolin, gentamicin, piperacillin, tobramycin, and trimethoprim/sulfamethoxazole were already over 20% in 2010. The resistance rates to many other antibiotics also steadily increased over time. Among the antibiotics tested in 2020, only amikacin, cefoxitin, imipenem, piperacillin/tazobactam, and tigecycline showed the resistance rates below 20%. Noticeably, ciprofloxacin also showed an increase in the resistance rate from 7.3% in 2010 (S 139 vs. R 11) to 27.78% in 2019 (S 104 vs. R 40) and even over 30% (33.96%) in 2020 (S 35 vs. R 18). CONCLUSIONS: Antibiotic resistance is a serious problem in pediatric UTIs. In the treatment of pediatric UTIs, more caution is needed in the use of antibiotics. It may be necessary to apply appropriate antibiotic management programs such as antibiotics steward program for pediatric patients. Failure of a proper response strategy coping with antibiotic resistance may accelerate the resistance crisis.

[Risk factors for postoperative long-term hematuria in patients with benign prostatic hyperplasia].

OBJECTIVE: To explore the risk factors for long-term hematuria after operation in BPH patients. METHODS: We retrospectively analyzed the clinical data on 646 cases of BPH treated by transurethral surgery in Liyang People's Hospital from January 2015 to August 2020. According to the incidence of hematuria at 3 months or longer after surgery, we divided the patients into a hematuria and a non-hematuria group, recorded the related factors, and investigated the independent risk factors for long-term hematuria by univariate and multivariate analyses. RESULTS: Of the 646 BPH patients, 48 were found with and 598 without hematuria after transurethral surgery. Univariate analysis showed that hypertension, diabetes mellitus, residual prostate gland, urinary tract infection, bladder neck contracture, prostate cancer, urethral calculus, urethral stricture, excessive activity and constipation were the influencing factors (P < 0.05), while multivariate logistic regression analysis revealed that hypertension (P < 0.001), diabetes mellitus (P = 0.007), residual prostate gland (P = 0.013), urinary tract infection (P < 0.001), bladder neck contracture (P = 0.032), urethral calculus (P = 0.033) and urethral stricture (P = 0.001) were independent risk factors for long-term hematuria in the BPH patients after surgery. CONCLUSION: Complicated hypertension, diabetes mellitus, residual prostate gland, urinary tract infection, bladder neck contracture, urethral calculus and urethral stricture are independent risk factors for long-term hematuria in BPH patients after transurethral surgery.

TRANSIENT PSEUDOHYPOALDOSTERONISM SECONDARY TO URINARY TRACT INFECTION IN A MALE INFANT WITH UNILATERAL HYDRONEPHROSIS DUE TO PRIMARY OBSTRUCTIVE MEGAURETER: A CASE REPORT.

We present a case of transient form of type 1 pseudohypoaldosteronism (S-PHA) in a 1.5-month-old male infant who presented with lethargy, failure to thrive, severe hyponatremia (Na=118 mmol/L), hypochloremia (Cl=93 mmol/L) and fever due to urinary tract infection. Potassium levels were normal. Markedly elevated serum aldosterone level and elevated serum renin confirmed the diagnosis of pseudohypoaldosteronism. Renal ultrasound showed grade III hydronephrosis on the left kidney while contrast-enhanced voiding urosonography excluded the existence of vesicoureteral reflux, which raised suspicion of obstructive uropathy at the level of vesicoureteral junction. Serum sodium normalized after several days of intravenous fluids and antibiotic therapy, after which oral supplementation of sodium was introduced. The levels of 17-hydroxyprogesterone, adrenocorticotropic hormone, cortisol and thyroid-stimulating hormone were normal. Functional magnetic resonance urography conducted at the age of 3 months confirmed the diagnosis of primary congenital obstructive megaureter and the infant was referred to a pediatric surgeon. Although a rare occurrence, S-PHA can be a potentially life-threatening condition in infants if not recognized and treated appropriately. Therefore, serum concentrations of electrolytes should be obtained in every child diagnosed with obstructive anomaly of the urinary tract and/or acute cystopyelonephritis. On the other hand, every child diagnosed with S-PHA should be evaluated for obstructive anomaly of the urinary tract.

Urinary tract infection in patients with chronic kidney disease under conservative treatment.

OBJECTIVES: to assess the prevalence and associated risk factors for urinary tract infection in patients with chronic kidney disease under conservative treatment and identify the microorganisms isolated in the urine of these patients and the staging of chronic kidney disease. METHODS: a cross-sectional, analytical study carried out at the Conservative Treatment Outpatient Clinic of a university hospital in the city of São Paulo. RESULTS: the prevalence of urinary tract infection is 22%. The risk factors Diabetes Mellitus, hypertension, heart disease, neoplasms and thyroid and autoimmune diseases stand out in the infected group (p < 0.001). Most of the microorganisms found in urine cultures (87.9%) were Gram-negative, being Escherichia coli (50.70%), followed by Klebsiella pneumoniae (23.1%) and Enterococcus spp. (9.7%). CONCLUSIONS: the findings of this investigation reveal the intrinsic association between risk factors and microorganisms for the development of urinary tract infection.

Complicated urinary tract infection in patients with benign prostatic hyperplasia.

Complicated urinary tract infection (UTI) is a symptomatic urinary infection accompanied by functional or structural abnormalities of the genitourinary tract. Benign prostatic hyperplasia (BPH) is a major cause of lower urinary tract obstruction in male patients, and bladder outlet obstruction (BOO) secondary to BPH can lead to UTIs in men. However, no evidence has clearly shown that UTI in the aging male population is associated with either post-void residual urine or BOO. Screening for the presence of bacteriuria is recommended prior to any procedure manipulating the urinary tract, and imaging studies of the upper urinary tract are recommended to identify underlying abnormalities. Recurrent or persistent UTI in men with BPH is an indication for surgical treatment. Asymptomatic bacteriuria should be screened for and treated before transurethral resection of the prostate (TURP). In addition, antibiotic prophylaxis reduced the risk of UTI in patients undergoing TURP. The choice of specific antimicrobial for prophylaxis should be based on local pathogen prevalence and individual antibiotic susceptibility. Patients with severe systemic infections require hospitalization, and empirical therapy should include an intravenous antimicrobial regimen. Further prospective studies are needed to refine the treatment process for complicated UTI in patients diagnosed with BPH.

Algorithms to Enhance Empiric Antimicrobial Choice for Outpatients With Afebrile Complicated Cystitis Reflects Importance of Status of the Urinary Tract and Patient Place of Residence.

OBJECTIVE: To determine predictive factors for antimicrobial resistance patterns and to develop an antimicrobial treatment algorithm for afebrile outpatients presenting with complicated cystitis. MATERIALS AND METHODS: We performed a retrospective, single-center, cross-sectional study of 2,891 outpatients with a diagnosed afebrile complicated cystitis from 2012 to 2018. For patients with confirmed urinary tract infection and antimicrobial sensitivities, univariate analyses and multivariable regression models were used to determine odds ratios for predicting resistance to trimethoprim-sulfamethoxazole, ciprofloxacin, nitrofurantoin, first-generation cephalosporin, and third-generation cephalosporin for the 2012-2016 data. Antimicrobial choice algorithms were created using 2012-2016 results and tested on 2017-2018 data. RESULTS: For afebrile outpatients presenting with complicated cystitis, overall prevalence of resistance for trimethoprim-sulfamethoxazole, ciprofloxacin, nitrofurantoin, first-generation cephalosporin, and third-generation cephalosporin was 25.6%, 19.5%, 19.1%, 15.0%, and 6.9%, respectively. Consistent predictive factors influencing resistance to all 5 antimicrobials were patient place of residence (ZIP code), status of host urinary tract (complicated vs uncomplicated), and prior resistance to the antimicrobial. Resulting treatment algorithm for complicated cystitis (whether or not prior microbiologic data was available) outperformed real-life provider choice and our previously published algorithm for uncomplicated cystitis. CONCLUSION: Treatment algorithms for urinary tract infections are dependent on patient place of residence (ZIP code), status of the host urinary tract (complicated or uncomplicated), and prior urine culture resistance data. When using our complicated cystitis treatment algorithm regardless of uropathogen, our results outperformed real-life scenario provider choice and our prior published algorithm for uncomplicated cystitis, which can help guide empiric antimicrobial choice.

Clinical management of type C hepatic encephalopathy.

Type-C hepatic encephalopathy is a complex neurological syndrome, characteristic of patients with liver disease, causing a wide and complex spectrum of nonspecific neurological and psychiatric manifestations, ranging from a subclinical entity, minimal hepatic encephalopathy, to a deep form in which a complete alteration of consciousness can be observed: overt hepatic encephalopathy. Overt hepatic encephalopathy occurs in 30-40% of patients. According to the time course, hepatic encephalopathy is subdivided into episodic, recurrent and persistent. Diagnostic strategies range from simple clinical scales to more complex psychometric and neurophysiological tools. Therapeutic options may vary between episodic hepatic encephalopathy, in which it is important to define and treat the precipitating factor and hepatic encephalopathy and secondary prophylaxis, where the standard of care is non-absorbable disaccharides and rifaximin. Grey areas and future needs remain the therapeutic approach to minimal hepatic encephalopathy and issues in the design of therapeutic studies for hepatic encephalopathy.

An evaluation of multidrug-resistant (MDR) bacteria in patients with urinary stone disease: data from a high-volume stone management center.

PURPOSE: To investigate the prevalence of MDR bacteria in patients with urinary stones and the risk factors for its formation. METHODS: A retrospective study was performed among patients with urinary stones in Beijing Tsinghua Changgung Hospital from December 2014 to May 2018. Patients with positive urinary cultures and drug sensitivity results were included. MDR were defined as any bacteria that have resistance to at least one agent in at least three classes of antibiotics. Bacteria distribution and resistance patterns were calculated. RESULTS: 1655 patients with urinary stones were eligible for analysis, among which 367 patients had positive urinary culture, yielding 457 isolates of 45 species. Escherichia coli remained the most common organism with a prevalence of 29.3%, followed by Enterococcus faecalis (12.0%), Proteus mirabilis (10.5%), and Klebsiella pneumonia (6.8%). 44.4% isolates were identified as MDR. The three most common Gram-negative bacteria were Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae, with a MDR rate of 84.33%, 62.5%, and 48.39%, respectively. Drug-resistant rates were different between MDR and non-MDR in ampicillin, cefazolin, ceftriaxone, cefepime, gentamicin, amikacin, and levofloxacin (all with p value < 0.05). In multivariate analysis, indwelling catheters (OR 3.1, 95% CI 1.07-8.98) and antibiotics use in the last 3 months (OR 2.14, 95% CI 1.04-4.38) were significantly associated with MDR formation. CONCLUSIONS: MDR bacteria were common among patients with urinary stones in our center and achieved high drug-resistant rates in ampicillin, first-generation and part of third-generation cephalosporins, and fluoroquinolones. Indwelling catheters and antibiotics used in the last 3 months were independent risk factors for MDR formation. Tailored antibacterial strategies still should be established according to the local bacterial spectrum and patient condition.

Does cranberry extract reduce antibiotic use for symptoms of acute uncomplicated urinary tract infections (CUTI)? Protocol for a feasibility study.

BACKGROUND: Consultations in primary care for symptoms of urinary tract infections (UTIs) are common and patients are frequently treated with antibiotics. Given increasing antimicrobial resistance, there has been interest in non-antibiotic treatment options for common infections. One such option is the use of cranberry extract to treat symptoms attributable to UTIs. METHODS: A target of 45 women consulting in primary care, with symptoms suggestive of an uncomplicated UTI for whom the practitioner would normally prescribe antibiotics, will be randomised to receive one of three treatment approaches: (1) immediate prescription for antibiotics; (2) immediate prescription for antibiotics plus a 7-day course of cranberry capsules and (3) cranberry capsules plus a delayed prescription for antibiotics to be used in case their symptoms do not get better, or get worse. Follow-up will be by daily rating of symptoms and recording of treatments used for 2 weeks in an online symptom diary. Interviews will be conducted with around 10-15 study participants, as well as with around 10-15 women who have experienced a UTI but have not been approached to take part in the study. Both groups will be asked about their experience of having a UTI, their thoughts on non-antibiotic treatments for UTIs and their thoughts on, or experience of, the feasibility trial. The primary objective is to assess the feasibility of undertaking a full trial in primary care of the effectiveness of cranberry extract to reduce antibiotic use for symptoms of acute uncomplicated UTI. The secondary objective is to conduct a preliminary assessment of the extent to which cranberry might reduce antibiotic use and symptom burden. DISCUSSION: This feasibility study with embedded interviews will inform the planning and sample size calculation of an adequately powered trial to definitively determine whether cranberry helps to alleviate the symptoms of acute uncomplicated UTIs in women and whether it can safely reduce antibiotic use. TRIAL REGISTRATION: ISRCTN registry, ID: 10399299. Registered on 24 January 2019.

In-Vitro Biofilm Formation and Antimicrobial Resistance of Escherichia coli in Diabetic and Nondiabetic Patients.

BACKGROUND: Diabetic patients are more susceptible to urinary tract infection compared to nondiabetic patients, Escherichia coli being the most common uropathogen causing UTI. Unreasonable and incorrect antibiotic prescription for UTI in these patients may induce the development of antibiotic-resistant urinary pathogens resulting in delayed recovery and longer hospitalization. In addition to these, biofilm forming capacity of the pathogen may worsen the problem. The main aim of this cross-sectional study (conducted from March to September 2015) is to detect the biofilm forming capacity of UTI causing micro-organisms and compare the antibiotic resistance pattern of Escherichia coli, the most common cause of UTI, which will help the physician in choosing the best antibiotic. METHOD: Total of 1,099 clean-catch mid stream urine (CCMSU) was processed by standard microbiological technique; 182 were from the diabetic group and 917 nondiabetic. Following identification, all isolates were subjected to antibiotic susceptibility testing using modified Kirby-Bauer disc diffusion method. In-vitro biofilm forming capacity of the isolates were detected by Microtitre plate method. The data were analyzed using SPSS software 16. RESULT: Urinary tract infection was found to be significantly higher in diabetic patients (42.9%) compared to nondiabetic patients (17.4%) with Escherichia coli as the most common uropathogen in both diabetic and nondiabetic groups. Similarly, UTI was more common in elderly population (29.5%). Imipenem, nitrofurantoin and amikacin were found to be the most effective drug for uropathogenic E. coli in both diabetic and nondiabetic patients, whereas amoxicillin, ciprofloxacin, and cotrimoxazole were least effective. Of the total bacterial isolates, 43.3% showed positive results for in-vitro biofilm production by the Microtitre plate method. A significantly higher resistance rate was observed among biofilm producing E. coli for quinolones, cotrimoxazole, and third generation cephalosporin ceftriaxone. Most of the biofilm producers (79.5%) were found to be MDR (p-value 0.015). CONCLUSION: Elderly populations with diabetes are at a higher risk of UTI. Higher biofilm production and resistance to in-use antimicrobial agents in this study render its inefficacy for empirical treatment and point out the importance of biofilm screening to ensure the effective management of infection.

An overview of reactive arthritis.

Reactive arthritis, also known as Reiter syndrome, is a spondyloarthropathy that typically follows a urogenital or gastrointestinal infection, and is characterized by conjunctivitis, urethritis, and arthritis. The frequency of reactive arthritis in the United States is estimated at 3.5 to 5 patients per 100,000. Physician assistants (PAs) can manage the condition; therefore, they should be familiar with the disease's signs and symptoms, diagnostic criteria, and treatment regimens. Without proper management, reactive arthritis can progress to a chronic destructive arthritis. Prompt recognition of the condition is key to early intervention and a better patient outcome with fewer complications.

Perinatal risk factors for type 1 diabetes revisited: a population-based register study.

AIMS/HYPOTHESIS: Single-centre studies and meta-analyses have found diverging results as to which early life factors affect the risk of type 1 diabetes during childhood. We wanted to use a large, nationwide, prospective database to further clarify and analyse the associations between perinatal factors and the subsequent risk for childhood-onset type 1 diabetes using a case-control design. METHODS: The Swedish Childhood Diabetes Register was linked to the Swedish Medical Birth Register and National Patient Register, and 14,949 cases with type 1 diabetes onset at ages 0-14 years were compared with 55,712 matched controls born from the start of the Medical Birth Register in 1973 to 2013. After excluding confounders (i.e. children multiple births, those whose mother had maternal diabetes and those with a non-Nordic mother), we used conditional logistic regression analyses to determine risk factors for childhood-onset type 1 diabetes. We used WHO ICD codes for child and maternal diagnoses. RESULTS: In multivariate analysis, there were small but statistically significant associations between higher birthweight z score (OR 1.08, 95% CI 1.06, 1.10), delivery by Caesarean section (OR 1.08, 95% CI 1.02, 1.15), premature rupture of membranes (OR 1.08, 95% CI 1.01, 1.16) and maternal urinary tract infection during pregnancy (OR 1.39, 95% CI 1.04, 1.86) and the subsequent risk of childhood-onset type 1 diabetes. Birth before 32 weeks of gestation was associated with a lower risk of childhood-onset type 1 diabetes compared with full-term infants (OR 0.54, 95% CI 0.38, 0.76), whereas birth between 32 and 36 weeks' gestation was associated with a higher risk (OR 1.24, 95% CI 1.14, 1.35). In subgroup analyses (birth years 1992-2013), maternal obesity was independently associated with subsequent type 1 diabetes in the children (OR 1.27, 95% CI 1.15, 1.41) and rendered the association with Caesarean section non-significant. In contrast to previous studies, we found no association of childhood-onset type 1 diabetes with maternal-child blood-group incompatibility, maternal pre-eclampsia, perinatal infections or treatment of the newborn with phototherapy for neonatal jaundice. The proportion of children with neonatal jaundice was significantly higher in the 1973-1982 birth cohort compared with later cohorts. CONCLUSIONS/INTERPRETATION: Perinatal factors make small but statistically significant contributions to the overall risk of childhood-onset type 1 diabetes. Some of these risk factors, such as maternal obesity, may be amendable with improved antenatal care. Better perinatal practices may have affected some previously noted risk factors over time.

Therapeutic potential of medicinal plants for the management of urinary tract infection: A systematic review.

Urinary tract infection (UTI) is one of the most severe public health problem affecting both sexes but females are more susceptible due to the differences in urogenital and reproductive anatomy, physiology and lifestyle. As in UTI, different parts of the urinary tract are affected and morbidity due to UTI is more common in women of all ages and older men. Due to multi-drug resistant strains and high recurrence rate, UTI has become a major socioeconomic burden. The current review article was aimed to describe the natural therapeutic strategies to manage and cure the UTI. For this purpose, different databases including Google Scholar, Cochrane database, and PubMed etc. were explored. Inclusion criteria were any research article investigating the current therapy of UTI. It was found that microbial infections including Escherichia coli, Enterococcus faecalis and Klebsiella species are the major causes of UTI with different signs and symptoms including painful urination or dysuria, hematuria, urinary urgency, burning micturition, frequent urination, nausea, and vomiting. Antibiotics like trimethoprim, sulfamethoxazole, quinolone etc. as the first choice of the drug are used worldwide. However, due to microbial resistance, several life-threatening side effects, repeated high doses, high cost and low efficacy of these antibiotics motivated the researchers to explore natural remedies for the treatment of UTI. Herbal medicines are effective to combat bacterial resistance with high efficacy, and easy availability with minimal or no side effects. For these reasons it has attained the attention of researchers wanting to explore the herbal treatment of UTI. Vaccinium macrocarpon, Tribulus terrestris, Trachyspermum copticum, Cinnamomum verum and Hybanthusenn easpermus are some common medicinal plants reported to have therapeutic potential for the management and cure of the UTI. Although herbal medicines have more potential over conventional medicine but more discoveries are required to explore the phytoconstituents and their mechanism of action responsible for the management and cure of UTI.

Higher Gestational Choline Levels in Maternal Infection Are Protective for Infant Brain Development.

OBJECTIVE: To assess whether maternal choline decreases effects of mothers' infections on fetal brain circuit development and on expression of infant behavior at 1 year of age. STUDY DESIGN: A cross-sectional study was conducted in a public hospital obstetrics and midwifery service, with prenatal assessments of maternal infection, C-reactive protein, and choline level and postnatal assessments of cerebral neuronal inhibition in 162 newborns. At 1 year, 136 parents completed reports of their child's behavior. RESULTS: Maternal infection at 16 weeks of gestation, experienced by 41% of mothers, raised mean maternal C-reactive protein (d' = 0.47, P = .002) and decreased the development of cerebral inhibition of auditory response at 1 month of age (d' = 0.39, P < .001). Decreased newborn cerebral inhibition manifested as decreased behavioral self-regulation at 1 year. Greater choline levels in mothers with infections were associated with improved newborn inhibition of auditory cerebral response, mitigating the effect of infection (ß = -0.34 [95% CI, -5.35 to -0.14], P = .002). At 1 year of age, children of mothers with infection and greater gestational choline levels had improved development of self-regulation, approaching the level of children of mothers without infection (ß = 0.29 [95% CI 0.05-0.54], P = .03). CONCLUSIONS: Greater maternal choline, recommended by the American Medical Association as a prenatal supplement, is associated with greater self-regulation among infants who experienced common maternal infections during gestation. Behavioral problems with diminished self-regulation often lead to referrals to pediatricians and might lead to later mental illness.

Vitamin A supplementation is effective for improving the clinical symptoms of urinary tract infections and reducing renal scarring in girls with acute pyelonephritis: a randomized, double-blind placebo-controlled, clinical trial study.

INTRODUCTION: It is believed that tubulointerstitial inflammation plays a role in the formation of renal scarring secondary to acute pyelonephritis (APN). Vitamin A is an anti-inflammatory agent that is involved in the re-epithelialization of damaged mucosal surfaces. OBJECTIVE: The aim of this study was to evaluate the efficacy of vitamin A supplementation in combination with antibiotics for improving urinary tract infections (UTIs) symptoms and preventing renal scarring in girls with APN. STUDY DESIGN: This randomized, double-blind, placebo-controlled clinical trial was conducted on 90 girls aged 2 to 12 years old between 2015 and 2017. Patients with UTIs and first episode of APN diagnosed based on 99 mTc-DMSA scintigraphy (uptake defect) were assessed for eligibility. Patients were randomly divided into two groups that either received 10 days of oral vitamin A (intervention group) or 10 days of placebo (control group) in addition to antibiotics during the acute phase of infection. The clinical response was considered as the primary outcome [duration (positive days) of UTI symptoms during trial treatment period] and secondary outcomes (no change, improving and or worsening of 99 mTc-DMSA scan results 6 months after treatment from baseline). P < 0.05 was considered to be statistically significant. RESULTS: Seventy-four patients (vitamin A group: 36 patients, placebo: 38 patients) were included in the analysis. The mean age was 5.25 ± 1 year old. Three patients (7.89%) in the placebo group and 2 patients (5.55%) in the vitamin A group had vesicoureteral reflux (VUR) (p = 0.114). Duration of fever (vitamin A group: 1.8 days, placebo: 3.1 days, p = 0.0026), urinary frequency (1.3 days vs. 2.8 days, p = 0.003) and poor feeding (2.3 days vs. 4.2 days, p = 0.005) were significantly lower in the vitamin A group. Following the second 99 mTc-DMSA scan, worsening of lesions was observed among 8 (22.2%) and 17 (44.7%) patients in the vitamin A and placebo groups, respectively (p = 0.003). 63.8% (23 patients) of the vitamin A group and 21% (8 patients) of placebo group showed lesion improving in the photopenic region. (P < 0.0001) There was no evidence of vitamin A intolerance. DISCUSSION: Our results show the efficacy of vitamin A supplementation on reducing renal scarring secondary to APN and on fever, urinary frequency and poor feeding duration in girls with APN. CONCLUSION: Vitamin A supplementation is effective for improving the clinical symptoms of UTI and reducing renal injury and scarring following APN in girls with first APN. However, larger randomized clinical trials (RCTs) with longer follow up are needed to confirm these effects.
