Characteristics of Urinary Tract Infections and the Use of Cranberry Products in Patients With Urinary Diversions: A Narrative Review.

PURPOSE: The aim of this narrative literature review was to summarize evidence regarding bacteriuria and urinary tract infections (UTIs) in patients living with a urinary diversion and the use of cranberry products for the prevention of these infections. METHODS: We searched for articles in the English language and available in full text to address the role of cranberry products in the management of UTIs in those with urinary diversions. We searched the electronic databases of MEDLINE, PubMed, and the Cochrane Central Register of Controlled Trials between January 2003 and December 2023. Thirty-two elements were read in full and 9 elements that evaluated UTIs and/or the role of cranberries in preventing UTIs are included in this narrative review. RESULTS: Research indicates no significant difference in UTI rates, microbiology, or antibiotic sensitivity and resistance patterns between the different types of urinary diversions (orthoptic diversions, ileal conduit diversions, and continent cutaneous diversions). Similar to persons with an intact urinary tract, Escherichia coli (a prevalent coliform bacteria) was the most prevalent pathogen resulting in symptomatic UTIs. In addition, we found that E. coli strains persisted in urinary diversions involving reconstructed intestinal segments for prolonged periods of time despite antibiotic treatment. We found sparse evidence suggesting that cranberry products are effective for the prevention of UTIs after ileal conduit urinary diversion. CONCLUSIONS: There are inconsistencies in the definition of bacteriuria in the literature making it difficult to compare findings among the studies. Clinical guidance discussing the optimal method for obtaining a urine specimen from a urinary diversion and its management is limited. Research studies on the use of cranberry products to treat UTIs in persons living with a urinary diversion are urgently needed.

Uro-pathogens: Multidrug resistance and associated factors of community-acquired UTI among HIV patients attending antiretroviral therapy in Dessie Comprehensive Specialized Hospital, Northeast Ethiopia.

BACKGROUND: Urinary tract infections are common bacterial and fungal infections in humans, occurring both in the community and in immunocompromised patients in healthcare settings. Urinary tract infections have a significant health impact on HIV-infected patients. Nowadays, drug-resistant pathogens are widespread poses a serious clinical risk, and causes urinary tract infection. The common agents of bacteria and fungi that cause urinary tract infection are Escherichia coli followed by Klebsiella pneumonia, Staphylococcus saprophyticus, Enterococcus faecalis, group B streptococcus, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus and Candida. albicans. This study aimed to investigate uro-pathogen, multidrug resistance pattern of bacteria, and associated factors of community-acquired urinary tract infection among HIV-positive patients attending antiretroviral therapy in Dessie comprehensive specialized hospital, Northeast Ethiopia from February 1, 2021, to March 30, 2021. METHODS: An institutional-based cross-sectional study was conducted at Dessie Comprehensive Specialized Hospital. Socio-demographic and clinical data were collected by using structured questionnaires from HIV patients suspected of community-acquired urinary tract infections. About 10 ml of clean-catch midstream urine was collected and inoculated into Blood agar, MacConkey, and Cysteine lactose electrolyte deficient media. Yeasts were identified by using Gram stain, germ tube test, carbohydrate fermentation, assimilation tests, and chromogenic medium. Gram stain and biochemical tests were performed to identify isolates and an antimicrobial susceptibility pattern was performed on disc diffusion techniques. Data were entered and analyzed using SPSS version 25. Both bivariate and multivariable logistic regression analysis was performed and a P value of < 0.05 with an adjusted odds ratio with their 95% confidence interval (CI) was used as statistically significant associations. RESULTS: From the total 346 study participants, 92 (26.6%) were culture positive 75 (81.52%) were bacterial and 17 (18.48%) were fungal pathogens. From a total of 75 bacteria isolates 51(68%) were Gram-negative bacteria and the most commonly isolated bacteria were E. coli 16 (21.33%) followed by K. pneumoniae 11(14.67%) and enterococcus species 10(10.87. Of the 17 fungal isolates of fungi, 8(47.1%) were represented by C. tropicalis. Of the isolated bacteria, 61(81.3%) were resistant to three and above classes of antibiotics (drug classes). About 13 (81.3%) of E. coli, 9(81.8%) of K. pneumoniae, 8(80%) of Enterococcus species, 7 (77.8%) of P. aeruginosa, and CoNs 7(87.5%) were the most frequently exhibited three and above classes of antibiotics (multi-drug resistance). Amikacin and gentamicin were effective against Gram-negative Uro-pathogens. Participants aged>44year, female, being daily labor, being farmer, unable to read and write, patients with CD4 count of ≤ 200 cells/mm3 and CD4 count of 201-350 cells/mm3, who had chronic diabetics, patients having a history of hospitalization and who had urgency of urinations were statistically significant association with significant urinary tract infections. CONCLUSION: The burden of community-acquired urinary tract infections among HIV patients is alarmingly increased. Therefore, behavior change communications might be considered for promoting the health status of HIV patients. Moreover, CD4 level monitoring and therapeutics selection based on microbiological culture are quite advisable for the management of urinary tract infections of HIV patients.

Protocol for surveillance of antimicrobial-resistant bacteria causing community-acquired urinary tract infections in low-income countries.

The spread of drug-resistant bacteria into the community is an urgent threat. In most low-middle-income countries (LMICs) settings, community-acquired infection (CAI) is empirically treated with no data to support the choice of antibiotics, hence contributing to resistance development. Continuous antimicrobial resistance (AMR) data on community-acquired pathogens are needed to draft empirical treatment guidelines, especially for areas with limited culture and susceptibility testing. Despite the importance of addressing antibiotic-resistant pathogens in the community setting, protocols for the surveillance of AMR bacterial infections are lacking in most (LMICs). We present a protocol for surveillance of AMR in LMICs using urinary tract infection (UTI) as a proxy for CAI to enable users to quantify and establish the drivers of AMR bacteria causing UTI. The protocol intends to assist users in designing a sustainable surveillance program for AMR in the community involving children above two years of age and adults presenting to a primary health facility for healthcare. Implementation of the protocol requires initial preparation of the laboratories to be involved, surveillance areas, selection of priority bacteria and antimicrobials to be used, and the design of a coordinated sampling plan. Recruitment should occur continuously in selected health facilities for at least 12 months to observe seasonal trends of AMR. At least 10 mL of clean-catch mid-stream urine must be collected into 20 mL calibrated sterile screw-capped universal bottles lined with 0.2 mg boric acid and transported to the testing laboratory. Utilise the data system that generates standard reports for patient care to be shared internally and externally in the regions and the world through global platforms such as the Global Antimicrobial Resistance Surveillance System.

Use of Fever Duration to Guide Management of Urinary Tract Infection.

BACKGROUND: The appropriate duration of antimicrobial therapy for febrile urinary tract infection (fUTI) in children has not been established. This study examined the optimal duration of treatment for fUTI in children. METHODS: We created a protocol that used fever duration to determine the duration of antibiotic administration. Transvenous antibiotics were administered until 3 days after resolution of fever, followed by oral antibiotics for 1 week. Diagnosis of fUTI was based on a fever of 37.5°C or higher and a quantitative culture of catheterized urine yielded a bacteria count of ≥5 × 104. Acute focal bacterial nephritis (AFBN) and pyelonephritis (PN) were diagnosed on the basis of contrast-enhanced computed tomography (eCT) findings. We retrospectively reviewed treatment outcomes. RESULTS: Of the 78 patients treated according to our protocol, data from 58 were analyzed-49 children (30 boys) had PN and nine (three boys) had AFBN. Blood test results showed that patients with AFBN had significantly higher white blood cell counts and C-reactive protein levels than did those with PN; however, urinary findings and causative bacteria did not differ between groups. Time to resolution of fever and duration of intravenous antibiotic administration were significantly longer in patients with AFBN than in those with PN. However, average duration of AFBN treatment was 14.2 days, which was shorter than the previously reported administration period of 3 weeks. No recurrence was observed in AFBN patients. CONCLUSIONS: A protocol that used fever duration to determine the duration of antimicrobial treatment was useful. Invasive examinations, such as eCT, were not required.

Individualized Traditional Chinese Medicine treatment antibiotics for recurrent urinary tract infections: a multicenter, randomized controlled study.

OBJECTIVE: To systematically assess the effects of individualized Chinese medicines on recurrent urinary tract infections (rUTIs). METHODS: This study recruited 230 adult female patients in the remission phase of rUTIs from five hospitals in China. The patients were randomly allocated to two groups: an individualized Chinese medicine group (n = 114) and a control group (n = 116). Patients in the Chinese medicine group received individualized Chinese herbs, which were evaluated for syndrome differentiation. Patients in the control group received antibiotic treatment combined with a Chinese medicine placebo. The duration of treatment was three courses of four weeks each, with a three-month subsequent follow-up. UTI recurrence rate, Traditional Chinese Medicine (TCM) syndrome scores, 36-item Short Form Survey (SF-36) score, and urine secretory immunoglobulin A (SIgA) were measured and analyzed before and after treatment in each group. RESULTS: Patients from the Chinese medicine group exhibited significant decreases in both short- and long-term UTI recurrence rates compared with the control group (P < 0.05). The changes in TCM syndrome scores between the Chinese medicine and control groups were significant (P < 0.05). The changes in the average SF-36 quality-of-life scores in the Chinese medicine group were also significantly higher than those in the control group after treatment (P < 0.05). The Chinese medicine group also demonstrated a significant increase in urine SIgA expression. CONCLUSION: Taken together, compared to the often-used long-term antimicrobial prophylaxis during the remission stage of rUTIs, treating patients with an individualized Chinese medicine decoction by syndrome differentiation could effectively reduce the recurrence rate, improve the patients' TCM syndrome scores and quality of life, and enhance immunity, which in turn helps to prevent antibiotic resistance.

Prevalence of urinary tract infections in pregnant women and antimicrobial resistance patterns in women in Riyadh, Saudi Arabia: a retrospective study.

BACKGROUND: Urinary tract infections (UTIs) are one of the most common health problems worldwide and mainly affect women. This study aimed to evaluate the prevalence of UTIs in pregnant women and determine the antimicrobial resistance patterns of bacterial pathogens isolated from pregnant and nonpregnant women in Riyadh, Saudi Arabia. METHODS: This retrospective cohort study was conducted at an academic medical center in Riyadh, Saudi Arabia, from January to June 2022. The study included all urine cultures performed for adult women during the study period. We excluded urine culture performed for women on antibiotics prescribed for any infection, children, and men. Using the SPSS (version 27) package, descriptive statistics and chi-square tests were used to analyze the data, and p < 0.05 was considered to indicate statistical significance. RESULTS: A total of 2,418 urine cultures performed during the study period were included (985 and 1,433 for pregnant and nonpregnant women, respectively). The overall prevalence of UTIs in pregnant women was 5% (95% CI 3.6-6.4); 10 (1%) women were symptomatic, and 40 (4%) women were asymptomatic. Of the entire cohort, 244 (10.1%) women were diagnosed with UTIs based on bacterial cultures. The predominant bacteria in both pregnant and nonpregnant women were Escherichia coli (134, 54.9%), followed by Klebsiella pneumoniae (48, 19.6%). The antibiotic susceptibility criteria for Escherichia coli and Klebsiella pneumoniae were as follows: nitrofurantoin (94% and 18.8%, respectively), amoxicillin-clavulanic acid (82.8% and 70.8%, respectively), ciprofloxacin (65.7% and 83.3%, respectively), trimethoprim-sulfamethoxazole (65.7% and 79.2%, respectively) and cephalothin (47% and 68.8%, respectively). CONCLUSION: Compared to the findings of other similar studies, the prevalence of UTIs was lower in pregnant women. This may be because the patient population was composed of healthy and educated women who received prenatal education and underwent prenatal assessment as per institutional guidelines. Nitrofurantoin and amoxicillin-clavulanic acid are recommended for use as an empirical therapy for UTIs in pregnant and nonpregnant women because bacteria have the least amount of resistance to these drugs.

Antimicrobial resistance pattern of Uro-Pathogens emphasizing non-lactose fermenting gram negative bacilli.

Objectives: To identify various species of non-lactose fermenting gram-negative bacilli involved in urinary tract infections, and to determine their antimicrobial resistance pattern. METHODS: The retrospective, descriptive, cross-sectional study was conducted from January 1 to April 1, 2022, at the Dow University of Health Sciences, Karachi, and comprised data from the institutional diagnostic laboratory that was related to urine samples regardless of age and gender from January 1, 2020, to December 31, 2021. Data was analysed using SPSS version 25. RESULTS: Of the 103,887 urine samples, 41,280(39.7%) were positive, 51,146(49.2%) showed no bacterial growth, 11,000(10.6%) had non-significant bacterial growth and 461(0.4%) had mixed bacterial growth. Of the positive samples, 18359(44.5%) were positive in 2020, and 22,921(55.5%) in 2021. Gram-negative lactose fermenting bacteria included escherichia coli 23,123(22.3%) and klebsiella pneumoniae 2,993(2.9%), gram-negative non-lactose fermenting bacteria included pseudomonas aeruginosa 1,110(1.07%), and gram-positive bacteria included enterococcus 8,008(7.7%). Pseudomonas aeruginosa was most resistant against tobramycin 880(79.3%) and least resistant against piperacillin-tazobactam 146(13%). CONCLUSIONS: Piperacillin-tazobactam was highly sensitive drug against non-lactose fermenting uro-pathogens.

Comparative Genitourinary Safety of In-class Sodium-Glucose Cotransporter-2 Inhibitors among Patients with Heart Failure with Preserved Ejection Fraction: A Cohort Study.

PURPOSE: The American Heart Association recommended sodium-glucose cotransporter-2 inhibitors (SGLT2i) for the management of heart failure with preserved ejection fraction (HFpEF). However, little is known about their real-world in-class comparative safety in patients with HFpEF. We aimed to assess the comparative safety of SGLT2i in the risk of urinary tract infection (UTI) or genital infection separately or as a composite outcome among patients with HFpEF. METHODS: This cohort study using MarketScan® Commercial and Medicare supplemental databases (2012-2020) included patients aged ≥ 18 years with a diagnosis of HFpEF who initiated SGLT2i therapy. Three pairwise comparison groups were established: cohort 1, dapagliflozin versus canagliflozin; cohort 2, empagliflozin versus canagliflozin; and cohort 3, dapagliflozin versus empagliflozin. After stabilized inverse probability treatment weighting, Cox proportional hazards regression was used to compare the risk of UTI or genital infection separately or as a composite outcome in each cohort. RESULTS: The risk of the composite outcome did not significantly differ between canagliflozin and dapagliflozin (adjusted hazard ratio [aHR] 0.64; 95% confidence interval [CI] 0.36-1.14) or between empagliflozin and canagliflozin (aHR 1.25; 95% CI 0.77-2.05). Similarly, there was no evidence of difference between dapagliflozin and empagliflozin in this risk (aHR 0.76; 95% CI 0.48-1.21). The results of analyses separately assessing UTI or genital infection were similar. CONCLUSIONS: There was no significant difference in the risk of UTI or genital infection among patients with HFpEF who initiated canagliflozin, dapagliflozin, or empagliflozin.

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are used for the management of heart failure with preserved ejection fraction (HFpEF). It is important to assess their comparative risk of urinary tract infection (UTI) or genital infection among patients with HFpEF. We compared patients with HFpEF using SGLT2i in three pairwise groups: cohort 1, dapagliflozin versus canagliflozin; cohort 2, empagliflozin versus canagliflozin; and cohort 3, dapagliflozin versus empagliflozin. We found that there was no significant difference in the risk of genitourinary infections including UTI or genital infections among dapagliflozin, empagliflozin, and canagliflozin.

Diagnosing and Managing Urinary Tract Infections in Kidney Transplant Recipients.

In the article, the authors review antibiotic treatment options for both acute uncomplicated UTI and complicated UTI. In addition, they review alternative regimens which are needed in the setting of drug-resistant pathogens including vancomycin-resistant Enterococcus, -extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-E), carbapenem-resistant Enterobacterales, and carbapenem-resistant Pseudomonas, which are encountered with more frequency.

Cefepime-taniborbactam and CERTAIN-1: Can we treat carbapenem-resistant infections?

Wagenlehner and colleagues1 demonstrated non-inferiority and superiority with respect to a primary endpoint of composite success (microbiological plus clinical) of cefepime/taniborbactam vs. meropenem in treating complicated urinary tract infections and acute pyelonephritis caused by carbapenem-susceptible gram-negative bacteria in adults. A major area of interest in real-world application of cefepime/taniborbactam is its potential role in treating carbapenem-resistant infections, which deserves further investigation.

Fever lasting 48 hours as a predictive factor of ESBL-producing bacteria in non-critically ill patients with urinary tract infection.

Urinary tract infection (UTI) is the most prevalent urological condition worldwide. Choosing appropriate antibiotics for patients who have fever before receiving a culture result is challenging. This retrospective study enrolled patients 394 patients hospitalized at Gangneung Asan Hospital for UTI from May 2017 to April 2021. Fever at 48 h of hospitalization was the analysis point, as this is when the response to antibiotic therapy manifest, although the results of antibiogram are not available. Multivariate analysis was performed to assess the correlation between ESBL producing bacteria (EPB) and fever at 48 h. Overall, 36.3% of patients had EPB and 27.9% had fever at 48 h. In multivariate analysis, a significant positive association was found between EPB and fever (odds ratio 1.17, 95% CI 1.05-1.30, P = 0.004) Female had negative association with multivariate model (OR 0.83, 95% CI 0.73-0.94, P = 0.004). Diabetes did not demonstrate a significant association with EPB. (OR 1.10, 95% CI 0.99-1.22, P = 0.072). Fever at 48 h is associated with EPB and could be considered a predictive factor for EPB infection in patients with UTI. Antibiotic escalation may be considered in patients with fever at 48 h.

Postpartum infections and antimicrobial resistance of responsible pathogens in Ukraine: results a multicenter study (2020-2022).

OBJECTIVE: Aim: To determine the current prevalence of postpartum infections and antimicrobial resistance and antimicrobial resistance of responsible pathogens in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter prospective cohort study was conducted from January 2020 to December 2022 in fifteen hospitals from twelve regions of Ukraine. Definitions of healthcare- associated postpartum infection were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. Antibiotic susceptibility was done by the disc diffusion test as recommended by EUCAST. RESULTS: Results: Among 21,968 women, 6,175 (28.1%) postpartum infections were observed. Of all postpartum infection cases, 83.1% were detected after hospital discharge. The postpartum infection rates were 17.3% after cesarean section and 10.8% after vaginal delivery. The most common postpartum infection types were endometritis (17.3%), followed by urinary tract Infection (3.5%), mastitis (3.4%), surgical site infection (excluding endometritis) (2.4%), and episiotomy site infection (1.5%). The predominant postpartum infection pathogens in Ukraine were: Escherichia coli (10.4%), Enterococcus spp. (9.6%), Staphylococcus aureus (6.7%), Pseudomonas aeruginosa (5.8%), Enterobacter spp. (5.8%). In our study pathogens of postpartum infection had differently levels of resistance to antibiotics. CONCLUSION: Conclusions: Our results indicate that postpartum infections requiring medical attention are common in Ukraine and that most postpartum infections occur after hospital discharge, so that use of routine inpatient surveillance methods alone will lead to underestimation of postpartum infection rates. Optimizing the antibiotic prophylaxis may reduce the burden of postpartum infection, but prevention is the key element.

Gentamicin loaded niosomes against intracellular uropathogenic Escherichia coli strains.

Urinary tract infections (UTIs) are the most common bacterial infections and uropathogenic Escherichia coli (UPEC) is the main etiological agent of UTIs. UPEC can persist in bladder cells protected by immunological defenses and antibiotics and intracellular behavior leads to difficulty in eradicating the infection. The aim of this paper is to design, prepare and characterize surfactant-based nanocarriers (niosomes) able to entrap antimicrobial drug and potentially to delivery and release antibiotics into UPEC-infected cells. In order to validate the proposed drug delivery system, gentamicin, was chosen as "active model drug" due to its poor cellular penetration. The niosomes physical-chemical characterization was performed combining different techniques: Dynamic Light Scattering Fluorescence Spectroscopy, Transmission Electron Microscopy. Empty and loaded niosomes were characterized in terms of size, ζ-potential, bilayer features and stability. Moreover, Gentamicin entrapped amount was evaluated, and the release study was also carried out. In addition, the effect of empty and loaded niosomes was studied on the invasion ability of UPEC strains in T24 bladder cell monolayers by Gentamicin Protection Assay and Confocal Microscopy. The observed decrease in UPEC invasion rate leads us to hypothesize a release of antibiotic from niosomes inside the cells. The optimization of the proposed drug delivery system could represent a promising strategy to significatively enhance the internalization of antimicrobial drugs.

Bacterial aetiology, antimicrobial susceptibility patterns, and factors associated with urinary tract infection among under-five children at primary health facility, North-Western Tanzania.

BACKGROUND: Urinary tract infections (UTI) are common in under-five children, with significant consequences leading to bacteremia, dehydration, kidney scarring, and renal failure. The incidence of UTI varies with patients' demographics and geographic location. Limited studies have addressed UTI issues, particularly in children. We determined the proportion of UTI, bacterial aetiology, and antimicrobial susceptibility patterns and associated factors among under-five children at the district hospital between March and April 2023. METHODS: We conducted a cross-sectional study using a convenient non-probability sampling technique to collect urine samples from participants with signs and symptoms of UTI. Written informed consent was obtained from parents or guardians. We collected Participants' information using a pretested structured questionnaire. Urine samples were processed at the Regional Referral Hospital. All analyses were conducted using STATA version 15.0. We determined the factors associated with UTI using a modified Poisson model multivariable analysis of the modified Poisson model. The results were presented as a prevalence ratio and 95% confidence interval. The level of significance was specified at 0.05. RESULT: The study recruited 368 under-five children; 194 (52.7%) were males, and the median age (interquartile range) was 24 (13-36) months. Of all, 28.8% (95% CI-24.3-33.6) had culture-confirmed UTI. One hundred and six pathogens were isolated, the majority being Escherichia coli (E. coli), 37 (34.9%), and Staphylococcus aureus (S. aureus), 26 (24.5%). The susceptibility of E. coli to cefepime, piperacillin-tazobactam, nitrofurantoin, and meropenem ranged from 81.1% to 97.3%. S. aureus was most susceptible to nitrofurantoin (96.2%) and ciprofloxacin (92.3%). Multidrug resistance was observed in 33.0% of isolates. The proportion of Methicillin-resistant S. aureus and extended-spectrum beta-lactamases was 23.1% and 25%, respectively. UTI was observed more in patients presenting with vomiting, dysuria, and abdominal pain, patients below 24 months of age, nappy users, and uncircumcised males. CONCLUSION: Our study found a relatively high proportion of UTI among under-five children associated with vomiting, dysuria, abdominal pain, nappy use, and uncircumcision in males. The pathogens were least susceptible to (trimethoprim-sulfamethoxazole, gentamycin, ampicillin, and penicillin) the commonly used antibiotic. We advocate a thorough clinical analysis to detect the predictors of UTI and a periodic review of empirical treatment of UTI based on the antibiotic susceptibility pattern.

What to do about recurrent urinary tract infections: A review of evidence behind emerging therapies.

BACKGROUND: Recurrent urinary tract infections (rUTIs) can be debilitating for patients and pose an increasing challenge in the primary care setting. An efficient approach enables timely access and effective care for patients. Recent research and pharmaceutical developments have provided new avenues for treating this common condition. OBJECTIVE: A narrative review was conducted to provide a targeted overview of contemporary management strategies in rUTIs to assist primary care physicians in managing patients with rUTIs efficiently and effectively. DISCUSSION: Recurrent urinary tract infections require investigation and risk factor identification. Appropriate patient education in the primary care setting, behavioural modifications and commencement of non-antibiotic treatment might reduce rUTI. Certain patients might require referral to a urologist for consideration of other treatment strategies and further investigation.

Endogenous Endophthalmitis from Urinary Tract Infection Caused by Group B Streptococcus: A Case Report.

We present a case of endogenous endophthalmitis with urinary tract infection (UTI) caused by group B Streptococcus (GBS). An 86-year-old female initially presented with ocular pain and sudden visual disturbance of the left eye. The patient did not complain of other symptoms and had no history of recent ocular surgery or trauma. Endogenous endophthalmitis was clinically diagnosed based on ophthalmic examination, history, and lab results showing systemic infection. A few days later, GBS was identified in her aqueous humor, blood, and urine cultures. Intravitreal ceftazidime and vancomycin injections, as well as fortified ceftazidime and vancomycin eye drops, were used immediately after clinical diagnosis. However, the symptoms worsened despite repeated intravitreal injections, so evisceration was performed. Endogenous endophthalmitis caused by GBS is very virulent and may present without evident systemic symptoms. The early recognition of the disease and systemic work up, followed by prompt treatment, is necessary.

Risk factors and economic burden for community-acquired multidrug-resistant organism-associated urinary tract infections: A retrospective analysis.

The spread of multidrug-resistant organisms (MDROs) has resulted in a corresponding increase in the incidence of urinary tract infections (UTIs). The risk factors and hospitalization burden for community-acquired MDRO-associated UTIs are discussed herein. This retrospective study included 278 patients with community-based MDRO-associated UTIs from January 2020 to January 2022. The MDRO (n = 139) and non-MDRO groups (n = 139) were separated based on drug susceptibility results. Community-based MDRO-associated UTIs mainly occurred in the elderly and frail patients with a history of invasive urinary tract procedures. The MDRO group imposed a greater economic burden compared to the non-MDRO group. Independent risk factors for community-based MDRO-associated UTIs were as follows: white blood cell (WBC) count > 10.0 × 109/L (OR = 2.316, 95% CI = 1.316-3.252; P = .018); ≥3 kinds of urinary tract obstructive diseases (OR = 1.720, 95% CI = 1.004-2.947; P = .048); use of 3rd generation cephalosporins (OR = 2.316, 95% CI = 1.316-4.076; P = .004); and a history of invasive urologic procedures (OR = 2.652, 95% CI = 1.567-4.487; P < .001). Days of hospitalization, antibiotic use, and bladder catheter use were significantly greater in the MDRO group than the non-MDRO group (P < .05).

Spontaneous resolution or antibiotic effectiveness? Reflection on a case of pediatric urinary tract infections caused by Enterococcus raffinosus.

Enterococcus raffinosus, named by Collins et al. in 1989, is a cocci-shaped bacterium that typically appears in pairs or short chains. As a Gram-positive and non-motile bacterium, it grows at 10°C-45°C, exhibiting negative peroxidase activity [1]. It is a normal flora in the oropharynx and gastrointestinal tract of domestic cats [2] and can also be isolated from human rectal swabs [3], it belongs to the same genus Enterococcus as Enterococcus faecalis and Enterococcus faecium. Enterococcus faecalis and Enterococcus faecium constitute 90% of clinically isolated strains. However, the incidence of other enterococci, excluding E. faecalis and E. faecium, is on the rise [4]. In this case report, a patient with pediatric urinary tract infections caused by E. raffinosus was presented, and a summary of relevant literature was provided.
