Relation of poverty with treatment-seeking behavior and antibiotic misuse among UTI patients in Pakistan.

Objective: The current study aimed to assess the relation between multi-dimension poverty, treatment-seeking behavior, and antibiotic misuse among urinary tract infection (UTI) patients. Method: A cross-sectional approach was utilized to recruit patients who had a history of UTI in the previous month from two provinces of Pakistan. The treatment-seeking behavior and antibiotic misuse data were collected on a self-developed questionnaire, whereas the poverty data were collected on a modified multi-dimension poverty index (MPI). Descriptive statistics were applied to summarize the data. The logistic regression analysis was carried out to assess the association of multi-dimension poverty with patient treatment-seeking behavior and antibiotic misuse. Results: A total of 461 participants who had UTI symptoms in the previous month were recruited. Most of the participants in the severely deprived stage treated the UTI (p < 0.001); however, there was a high proportion of the participants who consulted with friends and family for UTI treatment (p < 0.001). The patients with deprivation status (deprived and severely deprived) were less associated with formal consultation. The poorer subgroups were less likely to practice antibiotic course completion. Conclusion: The current study highlighted that poverty plays an important role in antibiotic misuse. Poorer subgroups were associated with informal consultations and the incompletion of the antibiotic course. Further studies are needed to explore the potential role of poverty in treatment-seeking behavior and antibiotic misuse.

Assessment of interleukin 17A and 23 in the course of bladder cancer and selected benign urological diseases.

Several cytokines have been indicated to be significantly involved in urological diseases. Interleukin 17A (IL-17A) and interleukin 23 (IL-23) have recently received attention for their involvement in inflammatory diseases and cancers. The aim of the study was to show changes in the level of pro-inflammatory interleukins IL-17A and IL-23 in patients with bladder cancer (BC) and selected urological diseases. An important cognitive aspect was to study the interdependencies between the studied interleukins and to assess their diagnostic value for such diseases. The material for the study was urine sample from patients with BC, urinary tract infection (UTI), urolithiasis, benign prostatic hyperplasia (BPH), US (urethral stricture), which was compared to the urine sample of healthy people without urological disorders. Interleukin concentrations were measured by the immunoenzymatic method. The levels of IL-17A and IL-23 in the urine of patients with BC, UTI, BPH and US were significantly higher compared to the control group. Statistically significant differences were found in the level of both interleukins compared to the control group in all diseases except urolithiasis. IL-17A and IL-23 correlated with each other in patients with all urological diseases except urolithiasis. The results of the conducted studies showed that selected urological diseases changed the levels of IL-17A and IL-23 in the urine of patients. The observations made confirmed the participation of these interleukins in the course of the urological diseases, especially in BC, and allowed to classify them as potentially useful parameters for diagnostic purposes.

Does post acute care reduce the mortality of octogenarian and nonagenarian patients undergoing hip fracture surgery?

BACKGROUND: With the increasing number of elderly individuals worldwide, a greater number of people aged 80 years and older sustain fragility fracture due to osteopenia and osteoporosis. METHODS: This retrospective study included 158 older adults, with a median age of 85 (range: 80-99) years, who sustained hip fragility fracture and who underwent surgery. The patients were divided into two groups, one including patients who joined the post-acute care (PAC) program after surgery and another comprising patients who did not. The mortality, complication, comorbidity, re-fracture, secondary fracture, and readmission rates and functional status (based on the Barthel index score, numerical rating scale score, and Harris Hip Scale score) between the two groups were compared. RESULTS: The patients who presented with fragility hip fracture and who joined the PAC rehabilitation program after the surgery had a lower rate of mortality, readmission rate, fracture (re-fracture and secondary fracture), and complications associated with fragility fracture, such as urinary tract infection, cerebrovascular accident, and pneumonia (acute coronary syndrome, out-of-hospital cardiac arrest, or in-hospital cardiac arrest. CONCLUSIONS: PAC is associated with a lower rate of mortality and complications such as urinary tract infection, bed sore, and pneumonia in octogenarian and nonagenarian patients with hip fragility fracture.

Epithelial development of the urinary collecting system in the human embryo.

The urinary collecting system (UCS) consists of organized ducts that collect urine from the nephrons and transport it to the ureter and bladder. Understanding the histogenesis of the UCS is critical. Thirty human embryos between the Carnegie stages (CS) 18 and 23 were selected from the Congenital Anomaly Research Center, Kyoto, Japan. Epithelia of the UCS, ureter, and bladder of each sample were randomly selected. Histological findings of the epithelia were analyzed according to the following criteria: type of epithelium, presence or absence of glycogen, percentage of migrated nuclei, percentage of cells in mitosis, and the surrounding mesenchyme. A thickened epithelium lining a narrow luminal cavity was observed in the pre-expanded pelvic specimens at CS18-CS23. At CS23, after pelvic expansion, the UCS showed a thin epithelium with a large luminal cavity mainly located on the early branches, whereas the epithelium covering the subsequent branches had medium thickness. Histological characteristics differed depending on the UCS part and sample stage. The degree of differentiation was evaluated, revealing that in CS18-CS23 pre-expanded pelvis specimens, the undifferentiated epithelium was found in the zeroth to third/fifth generation, whereas at CS23, after pelvic expansion, a differentiated epithelium covered the UCS zeroth to seventh generation. In a comparison of the urothelial epithelium between the UCS, ureter, and bladder, we found that urinary tract differentiation may be initiated in the bladder, followed by the ureter, UCS zeroth to seventh generations, and finally, UCS eighth to end generations. An understanding of the histogenesis of embryonic stage UCS can aid in the clinical management of congenital urinary tract defects and other diseases.

Impact of Polypharmacy and Risk Factors for Exacerbation of Lower Urinary Tract Symptoms in Patients with Urological Conditions: A Retrospective Study in a Japanese Municipal Hospital.

Polypharmacy exacerbates lower urinary tract symptoms (LUTS). Japan exhibits a higher prevalence of concomitant medication use in drug therapy than other countries. Previous age- and sex-specific reports exist; however, none include patients of all ages. Therefore, this retrospective study determined the impact of polypharmacy and its associated risk factors on LUTS exacerbation in outpatients with urological conditions. We included patients receiving medication who visited the Department of Urology at the Gifu Municipal Hospital (Gifu, Japan) between January, 2018 and December, 2018. The association between LUTS and polypharmacy and the risk factors for LUTS exacerbation were investigated. Patients were categorized into two groups according to their polypharmacy status. We performed propensity score matching and compared the International Prostate Symptom Score (IPSS) between the groups using the unpaired t-test. Multiple logistic regression analysis was performed to examine the risk factors, including "polypharmacy" and "taking multiple anticholinergic medications" for LUTS exacerbation. When comparing the IPSS between the groups, the polypharmacy group was found to have significantly higher scores than the non-polypharmacy group in six items, including "total score" and "storage score." Multiple logistic regression analysis results showed high significance in three items, including "polypharmacy" (odds ratio (OR) = 1.67, 95% confidence interval (CI): 1.03-2.71) and "taking multiple anticholinergic medications" (OR = 8.68, 95% CI: 1.05-71.7). In conclusion, this study revealed that "polypharmacy" and "taking multiple anticholinergic medications" were risk factors for LUTS. Particularly, "polypharmacy" is associated with storage symptom exacerbation. Therefore, eliminating "polypharmacy" and "taking multiple anticholinergic medications" is expected to improve LUTS.

The Diagnosis and Treatment of Adult Urinary Tract Infections in the Emergency Department.

Emergency medicine has been called the art of "making complicated clinical decisions with limited information." This description is particularly relevant in the case of diagnosis and treatment of urinary tract infections (UTIs). Although common, UTIs are often challenging to diagnose given the presence of non-specific signs and symptoms and over-reliance on laboratory findings. This review provides an interdisciplinary interpretation of the primary literature and practice guidelines, with a focus on diagnostic and antimicrobial stewardship in the emergency department.

Kidney and urogenital abnormalities in Down syndrome: a meta-analysis.

BACKGROUND: Reviews on Down syndrome do not or only marginally address the issue of kidney and urogenital tract abnormalities, and lower urinary tract dysfunctions. Hence, we performed a meta-analysis of the literature.  METHODS: A literature search was undertaken in the Library of Medicine, Web of Science and Excerpta Medica. The search algorithm combined various keywords: (Down syndrome OR trisomy 21 OR mongolism) AND (kidney OR urinary tract OR bladder) AND (malformation OR dysfunction OR anomaly OR abnormality OR size). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used. RESULTS: Eight case-control studies were retained for the final analysis. Three studies addressed the prevalence of kidney and urogenital tract abnormalities: an increased pooled relative risk of 5.49 (95%-CI: 1.78-16.93) was observed in Down syndrome. Penile malformations, obstructive malformations (including urethral valves), dilated urinary tract system, and kidney hypodysplasia were especially common. Three reports addressed the prevalence of lower urinary tract dysfunction: an increased pooled relative risk of 2.95 (95%-CI: 1.15-7.56) was observed. Finally, an autoptic study and an ultrasound study disclosed a reduced kidney size in Down syndrome. CONCLUSIONS: This meta-analysis indicates that abnormalities of the kidney and urogenital tract, lower urinary tract dysfunctions, and a reduced kidney size present with an increased frequency in individuals with Down syndrome.

Healthcare-associated infections in postoperative patients with intracranial aneurysm in Ukraine.

OBJECTIVE: Aim: to investigate the epidemiology, microbiology, and risk factors for healthcare-associated infections (HAIs) in postoperative patients with intracranial aneurysm in Ukraine. PATIENTS AND METHODS: Materials and Methods: Retrospective cohort study was conducted from January 2018 to December 2022 in four tertiary care hospitals of Ukraine. The diagnostic criteria were based on specific HAI site were adapted from the CDC/NHSN case definitions. RESULTS: Results: Of 1,084 postoperative patients with intracranial aneurysm, 128 (11.4%) HAIs were observed. The most common of HAI type was possible ventilatorassociated pneumonia (38.2%) followed by central line-associated bloodstream infections (33.8%), catheter -associated urinary tract infection (18.5%), and surgical site infection (9.6%). Inpatient mortality from HAI was 5.1%. Emergency admission, mechanical ventilation, taking antiplatelet aggregation drugs, albumin reduction, hyperglycaemia, hyponatremia, surgical procedure, operation time > 4 h, mechanical ventilation, urinary catheter, and central venous catheterization were risk factors associated with HAI in patients with intracranial aneurysm surgery. A total of 26% cases of HAIs by MDROs were notified over the study period. Klebsiella spp. - essentially K. pneumoniae - were the most frequent, followed by Enterobacter spp. and Escherichia coli. Carbapenemase production in Enterobacterales constituted the most frequent mechanism of resistance, while ESBL-production in Enterobacterales and meticillin-resistance in Staphylococcus aureus (MRSA) were detected in 65,7% 62,3% and 20% of cases, respectively. CONCLUSION: Conclusions: The present study showed that HAIs is a common complication in postoperative patients with intracranial aneurysm in Ukraine and multidrugresistant organisms the major pathogen causing infection.

Are children with food allergies more likely to have lower urinary tract symptoms? A case-control study.

INTRODUCTION: There are multiple historic reports linking lower urinary tract symptoms (LUTS) in children with food allergies (FA), but contemporary studies are sparse. The objective of this study was to evaluate a potential link between FA and LUTS in the pediatric population. We hypothesized that children with FAs are more likely to have LUTS. MATERIALS AND METHODS: After local IRB approval, pediatric patients (6-17 years [y]) with FAs proven by positive skin prick and/or serum IgE testing were invited to participate. A control group of pediatric patients without FAs was also recruited. All families/legal guardians signed informed consent, and all children signed written assent. Each participant filled out the Vancouver Symptom Score (VSS), a validated questionnaire for dysfunctional elimination syndrome, and the Pediatric Incontinence Questionnaire (PinQ), a validated quality of life assessment for children with bladder dysfunction. Demographic and clinical information were obtained retrospectively. RESULTS: From 2019-2020, 26 children with FAs and 57 without agreed to participate. Mean age was 9.3 y (IQR 7.9 y-13.5 y). There were no differences in gender, age, or race between the two cohorts. There were no significant differences between the two groups in mean VSS score or mean PinQ score. Four children with FAs (15%) and 15 children without (26%) had VSS score ≥ 11 (p = 0.339), indicating dysfunctional elimination. The median PinQ score was 0 (IQR 0-2) in both cohorts. CONCLUSIONS: This study did not identify an association between FAs and LUTS in a population of pediatric patients with laboratory proven FAs.

DEFA1A3 DNA gene-dosage regulates the kidney innate immune response during upper urinary tract infection.

Antimicrobial peptides (AMPs) are host defense effectors with potent neutralizing and immunomodulatory functions against invasive pathogens. The AMPs α-Defensin 1-3/DEFA1A3 participate in innate immune responses and influence patient outcomes in various diseases. DNA copy-number variations in DEFA1A3 have been associated with severity and outcomes in infectious diseases including urinary tract infections (UTIs). Specifically, children with lower DNA copy numbers were more susceptible to UTIs. The mechanism of action by which α-Defensin 1-3/DEFA1A3 copy-number variations lead to UTI susceptibility remains to be explored. In this study, we use a previously characterized transgenic knock-in of the human DEFA1A3 gene mouse to dissect α-Defensin 1-3 gene dose-dependent antimicrobial and immunomodulatory roles during uropathogenic Escherichia coli (UPEC) UTI. We elucidate the relationship between kidney neutrophil- and collecting duct intercalated cell-derived α-Defensin 1-3/DEFA1A3 expression and UTI. We further describe cooperative effects between α-Defensin 1-3 and other AMPs that potentiate the neutralizing activity against UPEC. Cumulatively, we demonstrate that DEFA1A3 directly protects against UPEC meanwhile impacting pro-inflammatory innate immune responses in a gene dosage-dependent manner.

Molecular typing and virulence characteristics of Escherichia coli strains isolated from hospital and community acquired urinary tract infections.

BACKGROUND: The main causes of hospital- and community-acquired urinary tract infections (UTIs) are a group of Escherichia coli (E. coli) strains with multiple virulence factors known as uropathogenic E. coli. METHODS AND RESULTS: One hundred E. coli isolates from the urine specimens of hospital- and community-acquired UTI patients were characterized based on their virulence factors and genetic relatedness using PCR and RAPD‒PCR, respectively. Among all, the traT (71%), sitA (64%), ompT (54%), malX (49%), ibeA (44%), tsh (39%), hlyD (18%) and cnf1 (12%) genes had the highest to lowest frequencies, respectively. There was no significant difference between the frequency of tested virulence genes in E. coli isolates from inpatients and outpatients. The frequency of the hlyD gene was significantly greater in E. coli isolates from patients hospitalized in gynecology, dermatology and intensive care unit (ICU) wards than in those from other wards. Eight virulence gene patterns were common among the isolates of inpatients in different wards of the same hospital, of which five patterns belonged to the isolates of inpatients in the same ward. More E. coli isolates with similar virulence gene patterns and greater genetic similarity were found in female patients than in male patients. The analysis of the RAPD‒PCR dendrograms revealed more genetic similarities among the E. coli isolates from inpatients than among those from outpatients. CONCLUSION: Our findings indicate the presence of a wide variety of virulence factors in E. coli isolates and the possibility of spreading the same clones in different wards of the hospital.

Bacteriological profile, antimicrobial susceptibility, and factors associated with urinary tract infection in pregnant women.

INTRODUCTION: Urinary tract infection (UTI) is a common bacterial complication in pregnancy. The study aimed to estimate the prevalence, risk factors, and bacterial etiology of UTI during pregnancy and determine the efficacy of antimicrobial drugs in treating UTIs. METHODOLOGY: Urine specimens and clinical data were collected from pregnant women who attended primary health centers in Erbil, Iraq. All specimens were cultured on appropriate media and identified by standard microbiological methods. The pregnant women were grouped into symptomatic UTI group, asymptomatic bacteriuria group, and the control group. The agar dilution method was used to determine antimicrobial susceptibility. RESULTS: Among the 5,042 pregnant women included in this study, significant bacteriuria was found in 625 (12.40%) of the cases, and 198 (31.68%) had symptomatic UTI, of which 43.59% were diagnosed during the third trimester. Out of the 643 bacteria isolated, 33.28% were symptomatic UTI, of which 43.59% developed during the third trimester. There was a significant difference in the bacterial etiology between symptomatic UTI and asymptomatic bacteriuria (p = 0.002), as well as between cystitis and pyelonephritis (p = 0.017). The most common bacterial species isolated was Escherichia coli, which was susceptible to fosfomycin (100%), meropenem (99.45%), and nitrofurantoin (97.8%). CONCLUSIONS: Pregnant women are more likely to develop UTI in the third trimester. Escherichia coli is the predominant pathogen. The study suggests the use of fosfomycin, meropenem, and nitrofurantoin for the treatment of UTI. No Gram-positive isolates were resistant to daptomycin.

The role of payment sources in the continuation of rehabilitation therapy in tertiary hospitals for patients with traumatic spinal cord injury: a study in Southwest China.

Medical security support for rehabilitation therapy in China is different from that in other countries. We investigated whether the discharge plan to continue rehabilitation therapy in tertiary hospitals for patients after traumatic spinal cord injury (TSCI) was influenced by payment sources or other conditions. This was a cross-sectional, observational study. Information was collected on the general condition, caregiver, types of payment sources for continued rehabilitation, American Spinal Injury Association Impairment Scale (AIS) scores, and discharge plans. In total, 135 patients with TSCI (107 male, mean age 41.00 ± 13.73 years, mean spinal cord injury duration 238.43 ± 345.54 days) were enrolled. Medical insurance (43%) and out-of-pocket payments (27.4%) were the primary payment sources. Although most patients were beyond the acute phase, 40% continued rehabilitation therapy at other tertiary hospitals. The caregiver, payment sources, injury level, AIS level, and complete urinary tract infection (UTI) were different due to discharge plans (p > .05). Patients seemingly consider a higher AIS level and co-UTI as the requirement for tertiary hospital therapy. In non-medical insurance payment source patients, the discharge plan also differed due to the AIS level and co-UTI (p > .05). However, in medical insurance patients, the discharge plan differed only in terms of TSCI duration (p > .05). The restricted duration of medical coverage restricted the continuation of rehabilitation therapy and influenced the discharge plan of most patients with TSCI.

Pathogen-specific alterations in intestinal microbiota precede urinary tract infections in preterm infants: a longitudinal case-control study.

Urinary tract infections (UTIs) are among the most common late-onset infections in preterm infants, characterized by nonspecific symptoms and a pathogenic spectrum that diverges from that of term infants and older children, which present unique diagnostic and therapeutic challenges. Existing data on the role of gut microbiota in UTI pathogenesis in this demographic are limited. This study aims to investigate alterations in gut microbiota and fecal calprotectin levels and their association with the development of UTIs in hospitalized preterm infants. A longitudinal case-control study was conducted involving preterm infants admitted between January 2018 and October 2020. Fecal samples were collected weekly and analyzed for microbial profiles and calprotectin levels. Propensity score matching, accounting for key perinatal factors including age and antibiotic use, was utilized to match samples from UTI-diagnosed infants to those from non-UTI counterparts. Among the 151 preterm infants studied, 53 were diagnosed with a UTI, predominantly caused by Enterobacteriaceae (79.3%) and Enterococcaceae (19.0%). Infants with UTIs showed a significantly higher abundance of these families compared to non-UTI infants, for both Gram-negative and positive pathogens, respectively. Notably, there was a significant pre-UTI increase in the abundance of pathogen-specific taxa in infants later diagnosed with UTIs, offering high predictive value for early detection. Shotgun metagenomic sequencing further confirmed the dominance of specific pathogenic species pre-UTI and revealed altered virulence factor profiles associated with Klebsiella aerogenes and Escherichia coli infections. Additionally, a decline in fecal calprotectin levels was observed preceding UTI onset, particularly in cases involving Enterobacteriaceae. The observed pathogen-specific alterations in the gut microbiota preceding UTI onset offer novel insight into the UTI pathogenesis and promising early biomarkers for UTIs in preterm infants, potentially enhancing the timely management of this common infection. However, further validation in larger cohorts is essential to confirm these findings.

Urinary and reproductive tract infection symptoms and menstrual hygiene practices in refugee camps in Jordan: A cross-sectional study.

BACKGROUND: Urinary tract infections and reproductive tract infections pose significant health risks, particularly among women living in challenging conditions. Unhygienic menstrual practices can exacerbate these risks, impacting physical and psychological well-being. OBJECTIVES: This study assessed the association between unhygienic menstrual care and self-reported urinary tract infection/reproductive tract infection symptoms among refugee women. In addition, it explored the association between these symptoms and mental health, specifically depressive symptoms. DESIGN: This study adopted a cross-sectional observational design. METHODS: This study was conducted between January and March 2023, involving 387 reproductive-age refugee women. Data collected included sociodemographic information and urinary tract infection/reproductive tract infection symptoms. In addition, we used the Menstrual Practice Needs Scale to evaluate menstrual hygiene practices and the Patient Health Questionnaire-9 for depressive symptoms. Statistical analysis was performed using Python version 3.9.12. RESULTS: Of 387 refugee women, 92.25% reported having urinary or reproductive tract infection symptoms in the previous 3 months. Factors like older age (odds ratio = 1.764, 95% confidence interval = 1.083-2.873, p-value = 0.023), lower family income (odds ratio = 0.327, 95% confidence interval = 0.138-0.775, p-value = 0.011), lower educational level (odds ratio = 0.222, 95% confidence interval = 0.068-0.718, p-value = 0.012), and being married (odds ratio = 0.328, 95% confidence interval = 0.188-0.574, p-value < 0.001) were significantly associated with urinary or reproductive tract infection risk. Difficulties obtaining menstrual products and thus reusing them increased the odds of urinary or reproductive tract infection diagnosis (odds ratio = 2.452, 95% confidence interval = 1.497-4.015, p-value < 0.001). Women with urinary or reproductive tract infection symptoms exhibited higher Patient Health Questionnaire-9 scores than those without (12.14 ± 5.87 vs 9.99 ± 5.86, p-value < 0.001, respectively). CONCLUSION: This study highlights a high prevalence of urinary or reproductive tract infection symptoms among refugee women residing in camps in Jordan, which was associated with poor menstrual hygiene practices and depressive symptoms. To reduce the urinary tract infection/reproductive tract infection burden in marginalized communities, public health initiatives should enhance healthcare accessibility, provide reproductive education, and promote holistic well-being practices for refugee women.

Rare Urinary Tract Infections in Immunosuppressed Patients: Not Just Anti-Infectives.

Null.

A case report of three people experiencing intractable autonomic dysreflexia following instillation of Uro-Tainer® Polyhexanide 0.02.

INTRODUCTION: Historically, bladder washouts were used to instil therapeutic reagents directly into the bladder. This practice has expanded to include instillation of solutions that deal with catheter issues such as encrustation or formation of bio-film. They appear to provide a promising strategy for people with long term catheters. These products are readily available to purchase, but there is concern that people are using these solutions without a complete understanding of the purpose for the rinse and without clinical guidance to monitor response to treatment. CASE PRESENTATION: These case studies include three people living with spinal cord injury (SCI) who developed severe autonomic dysreflexia (AD) when a catheter rinse was carried out using a particular solution. Each of the cases developed immediate and, in some cases, intractable AD requiring further intervention to resolve symptoms. DISCUSSION: Catheter-associated urinary tract infection is a significant cause of morbidity and mortality in people living with SCI. Long-term catheters provide a vector for opportunistic micro-organisms to form bio-film and create an environment that promotes formation of struvite calculi, thus increasing the risk of chronic catheter blockage and urinary tract infection. Whilst these solutions are used to reduce these risks, they also pose additional risks to people susceptible to AD. These cases highlight the need for judicious patient selection and clinical oversight and management of adverse events when using catheter rinse solutions in certain people living with SCI. This is supported by a decision-making algorithm and a response to AD algorithm. This case report was prepared following the CARE Guidelines (supplementary file 1).
