Objective To explore the correlation between asymptomatic bacteriuria(AB)and surgical site infection(SSI)in middle-aged and elderly women undergoing open hysterectomy.Methods The clinical data of 1469 middle-aged and elderly women undergoing open hysterectomy in the Third Affiliated Hospital of Guizhou Medical University from June 2011 to August 2018 were retrospectively analyzed.Factors associated with SSI after operation were analyzed by univariate and multivariate regression models to identify the relationship of AB with SSI after open hysterectomy.Results Of these 1469 patients,101(6.88%)had SSI and 124 had AB[including 14 patients(11.29%)with infections].In addition,1345 patients had no AB,among whom 87(6.47%)had infections.Thus,the infection rate in patients with AB was significantly higher than that in patients without AB(=4.123,=0.042).Univariate analysis showed AB,history of diabetes mellitus,surgical procedure,length of stay(>15 d),season(summer and autumn),body mass index(≥25 kg/m ),nature of lesions(malignant tumors),ASA grade(>grade Ⅱ),incision length(≥10 cm),and operative time(≥3 h),bleeding volume(≥1000 ml),serum albumin concentration(<30 g/L),blood glucose(≥10 mmol/L),and hemoglobin concentration(<90 g/L)were associated with SSI(all <0.05).Multivariate analysis showed that AB,nature of lesions(malignant tumors),blood glucose(≥10 mmol/L),operative time(≥3 h),and ASA grade(>grade Ⅱ)were risk factors for SSI in these patients(all <0.05). Conclusions AB is one of the risk factors for SSI in middle-aged and elderly women undergoing open hysterectomy.Screening and treatment of AB before surgery can reduce the risk of SSI.ASA grading shall be performed before surgery before corresponding preparation was offered.Effective control of blood glucose,improved surgical skills,and shorter operative time are helpful for lowering postoperative SSI.

Periprosthetic joint infection (PJI) is one of the most serious complications after total joint arthroplasty (TJA). The prevalence of urinary tract infection (UTI) is common, particularly among elderly women, a group for whom TJA may be required. The association between preoperative UTI and increased risk of PJI after TJA is unclear. We reviewed key articles concerning the relationship between UTIs and PJI, and summarized recommendations of international consensus on PJI, which was established in Philadelphia in July of 2018. In addition, we distinguish between symptomatic UTI and asymptomatic bacteriuria, because their causative effects on PJI are quite different.

Urinary tract infections (UTIs) are infectious diseases that commonly occur in communities. Although several international guidelines for the management of UTIs have been available, clinical characteristics, etiology and antimicrobial susceptibility patterns may differ from country to country. This work represents an update of the 2011 Korean guideline for UTIs. The current guideline was developed by the update and adaptation method. This clinical practice guideline provides recommendations for the diagnosis and management of UTIs, including asymptomatic bacteriuria, acute uncomplicated cystitis, acute uncomplicated pyelonephritis, complicated pyelonephritis related to urinary tract obstruction, and acute bacterial prostatitis. This guideline targets community-acquired UTIs occurring among adult patients. Healthcare-associated UTIs, catheter-associated UTIs, and infections in immunocompromised patients were not included in this guideline.

The efficacy of antibiotic prophylaxis in radical prostatectomy (RP) remains to be established. We retrospectively compared the occurrence of perioperative infections after RP between the 2 different antibiotic protocols. This study involved 428 cases of laparoscopic radical prostatectomy (LRP). After excluding patients who had no perioperative urine culture data, 313 consecutive patients who underwent LRP for prostate carcinoma were classified into 2 groups according to the duration of antimicrobial prophylaxis. To group 1 (153 patients), a second-generation cephalosporin was administered for less than 2 days, whilst the remaining 160 patients in group 2 were administered the drug for more than 2 days. The overall incidence of postoperative bacteriuria was 50.8%, being significantly higher in group 1 (56.9%) than in group 2 (45%). The incidence of surgical site infection (SSI) was significantly higher in group 1 (5.2%) than in group 2 (0.6%). Multivariate analysis revealed that old age, duration of antibiotics for more than 2 days, and duration of Foley catheter placement were independently associated with postoperative infectious complications (all, P < 0.05). Multivariate analysis revealed that duration of antibiotics for more than 2 days, duration of Foley catheter placement, and duration of surgical drain placement were independently associated with postoperative SSI (all, P < 0.05). The incidence of postoperative bacteriuria and SSI were higher in patients who received antibiotics for a short duration. Based on our results, we demonstrated that the outcome of postoperative infectious complications is dependent on old age, short antibiotic administration duration, and prolonged Foley catheterization. Prolonged drain placement is associated with SSI, whilst a longer duration of antibiotics use and prolonged Foley catheterization are associated with a decrease in the incidence of SSI.

As the elderly population increases, so does the prevalence of urinary tract infections in the elderly population in long-term care facilities and the associated medical costs. Screening tests and treatment for asymptomatic bacteriuria in elderly residents in the community or in long-term care facilities are not recommended. However, febrile urinary tract infections should be treated with proper antibiotics. Patients who have risk factors for urinary tract infections require prompt therapy. Catheter-associated bacteriuria is the most common hospital-acquired infection. The most important risk factor associated with an increased likelihood of developing catheter-associated bacteriuria is the duration of catheterization. Long-term catheter indwelling should be avoided, and it is necessary to reduce unnecessary catheter insertion. Most patients are asymptomatic, and they do not require treatment. Symptomatic catheter-associated infections should be treated. The best strategy for reducing catheter-associated infections involves careful aseptic insertion of the catheter and maintenance of a closed dependent drainage system. Steps must be taken to reduce urinary tract infections and urinary catheter-related infections in light of the increasing elderly population.

PURPOSE: The aim of this study was to analyze the incidence and microbiological characteristics of urinary tract infection in infants aged younger three months and to compare with other infection with positive urine culture. METHODS: We retrospectively reviewed the medical records of 425 infants with a tympanic temperature >37.6℃, aged younger than three months, who were admitted to Cheil General Hospital in Seoul, Korea, from January 2013 to December 2016. Demographic and clinical features, laboratory findings, respiratory virus PCR and the pathogens of a urine culture were analyzed. RESULTS: A total of 88 infants (63 males, 25 females) had urinary pathogens detected in the urine culture test. The incidence of UTI in febrile infants aged younger 3 months was 11%. The most common pathogen which causes UTI was E. coli as same as in previous studies. They were divided into a UTI group (n=48) and a non-UTI group (n=40). In comparison of both group, leukocytosis, C-reactive protein level, Absolute neutrophil count level, peak temperature is statistically significant. In both group, there were co-infections with viral pathogens in some cases, and the odd ratio of non-UTI group with viral infection was 3.28. CONCLUSION: The study determined the incidence and pathogen of UTI in febrile infants, aged younger three months. E. coli was responsible for the majority UTI. There were some viral co-infections in febrile infants with bacteriuria and incidence was higher in non-UTI group. WBC count, ANC count and CRP level were the differentiating factors of UTI from non-UTI group.

Urinary tract infection (UTI) is common in patients with diabetes mellitus. Furthermore, UTI is more severe, more often caused by resistant pathogens, and produces worse outcomes in those with diabetes mellitus. Although some patients may have altered clinical signs, symptoms of UTI are similar in patients with or without diabetes mellitus. Treatment depends on severity of systemic symptoms, results of urine culture, and underlying diseases of patients. There are no definite indications to treat asymptomatic bacteriuria in patients with diabetes mellitus.

OBJECTIVES: The present study was undertaken to study the maternal risk factors for preterm birth (PTB) and low birth weight (LBW) with a special emphasis on assessing the proportions of maternal genitourinary and periodontal infections among Indian women and their association with adverse pregnancy outcomes. METHODS: A hospital-based prospective study comprising 790 pregnant women visiting the obstetrics clinic for a routine antenatal check-up was undertaken. Once recruited, all study participants underwent clinical and microbiological investigations for genitourinary infections followed by a dental check-up for the presence of periodontitis. The study participants were followed up until their delivery to record the pregnancy outcomes. Infectious and non-infectious risk factors for PTB and LBW were assessed using univariate and multivariate Cox regression analysis. Independent risk factors for PTB and LBW were reported in terms of adjusted relative risk (ARR) with the 95% confidence interval (CI). RESULTS: Rates of PTB and LBW in the study population were 7.6% and 11.4%, respectively. Previous preterm delivery (ARR, 5.37; 95% CI, 1.5 to 19.1), periodontitis (ARR, 2.39; 95% CI, 1.1 to 4.9), Oligohydramnios (ARR, 5.23; 95% CI, 2.4 to 11.5), presence of Nugent’s intermediate vaginal flora (ARR, 2.75; 95% CI, 1.4 to 5.1), gestational diabetes mellitus (ARR, 2.91; 95% CI, 1.0 to 8.3), and maternal height <1.50 m (ARR, 2.21; 95% CI, 1.1 to 4.1) were risk factors for PTB, while periodontitis (ARR, 3.38; 95% CI, 1.6 to 6.9), gestational hypertension (ARR, 3.70; 95% CI, 1.3 to 10.8), maternal height <1.50 m (ARR, 2.66; 95% CI, 1.3 to 5.1) and genital infection during later stages of pregnancy (ARR, 2.79; 95% CI, 1.2 to 6.1) were independent risk factors for LBW. CONCLUSIONS: Our study findings underscore the need to consider screening for potential genitourinary and periodontal infections during routine antenatal care in developing countries.
