Background: Pseudomonas.aeruginosa is among the most common opportunistic hospital pathogens, which exhibit an innate resistance and has developed increasing resistance to many useful antimicrobial agents over the last decades. This study investigated the occurrence of important types of ESBLs and MBLs in association with potential important virulence factors among P. aeruginosa isolates from feces of Jordanian infants.   Methods: A total of 302 feces samples were obtained randamely from neonates and infants admitted to Pediatric Clinic and the Neonate Intensive Care Unit (NICU)/Jordan University Hospital (JUH), over a  9-months period(2016- 2017). Fecal samples were cultured for P.aeruginosa and their growth was identified and tested using microbiological and antibiotic susceptibility methods. Additionly,  virulence factors, antimicrobial resistance genes and genotypes were detected using Polymerase Chain Reaction (PCR). Results: A total of 16/302 (5.3%) of P. aeruginosa isolates were recovered from feces samples. Antimicrobial susceptibility of the isolates ranged between the lowest 18.75% to meropenem and highest of 87.5% to azetreonam among 9 tested drugs. The percentage of specific genes of ESBLs and MBLs in 16 P.aeruginosa isolates were the following: blaOXA-50, blaTEM, blaCTX-M , blaVIM ,blaKPC , blaSHV ,blaGES, and blaVEB were detected at the rate of  13(81.2%), 13(81.2%), 12(75%), 12(75%), 11(68.7%), 10(62.5%), 2(12.5),1(6.2%), respectively. The percentage of the potential virulence genes in the same isolates were detected as follow:  lasB, algD , toxA, exo S and exo U at the rate of 100%, 87.5% , 81.2%, 81.2%,31.2, respectively. All P.aeruginosa isolates observed to develop beta-hemolysis on both human and sheep blood agar, and to produce either pyoverdin ((56.3%) or pyocyanin (43.7%).  Conclusions: The present study demonstrates high occurrence of multidrug resistant P.aeruginosa isolates in infant feces which carried high rates of important genes of ESBLs and MBLs and potential virulence factors.

Record Review

ObjectiveInfections with multidrug-resistant organisms (MDROs) such as Gram-negative bacteria have high morbidity and mortality with limited treatment options. Colistin, an antibiotic active against MDRO, was rarely used due to frequent adverse effects, but its use has now been recommended among adults. In this study, we determined the efficacy of colistin for the treatment of sepsis in neonates.Design/setting/patients/outcomesWe conducted a retrospective record review of all neonates admitted to the neonatal intensive care unit of Aga Khan University Hospital, Karachi, Pakistan, between June 2015 and June 2018, who had sepsis and received colistin by intravenous, inhalation and/or intrathecal routes. Predictors of colistin efficacy, for neonatal survival and microbial clearance, were assessed using multiple logistic regression.Results153 neonates received colistin; 120 had culture-proven sepsis; and 93 had MDR-GNB (84 colistin-sensitive). 111 (72.5%) neonates survived and were discharged from hospital; 82.6% had microbial clearance. Neonates with colistin-sensitive bacteria (adjusted OR (AOR)=3.2, 95% CI 2.8 to 4.0), and those in which colistin therapy started early (AOR=7.2, 95% CI 3.5 to 13.6) were more likely to survive. Neonates with increased gestational age (AOR=1.9, 95% CI 1.5 to 3.0), higher weight (AOR=5.4, 95% CI 3.3 to 11.8) and later onset of sepsis (AOR=4.3, 95% CI 2.0 to 9.0) had higher survival. Adverse events included nephrotoxicity in 5.2%; 13.7% developed seizures and 18.3% had electrolyte imbalance.ConclusionsColistin therapy was associated with survival among neonates suffering from MDR-GNB sepsis. The frequency of side effects was moderate.

Introduction: Non-neoplastic urinary bladder lesions are not life threatening, but are an important source to cause clinical symptoms and signs. However, neoplasms of the bladder are a source of morbidity, mortality, and exhibit more clinical challenges. Cystoscopy provides overall information about an anatomical/pathological condition of the urinary bladder which will be helpful for patients' management. A cystoscopic biopsy is a primary diagnostic tool for diagnosing urinary bladder cancer. Objectives: The objective of the study was to find the frequency and histomorphological characteristics of urinary bladder lesions in Dhulikhel Hospital, to find the clinical presentation of urinary bladder lesions and to grade the urothelial tumors based on the World Health Organization (WHO)/ International Society of Urological Pathology (ISUP) classification 2004. Methodology: This was a retrospective, cross-sectional, observational study carried out in the Department of Pathology, Dhulikhel Hospital-Kathmandu University Hospital. Convenient sampling was done. All cystoscopy biopsies received from January 2014 to December 2018 were studied. All tissue blocks were retrieved, cut, and stained with Hematoxylin and Eosin. The stained slides were examined under a light microscope by the primary investigator. Result: A total of 70 cystoscopic biopsies were analyzed. The majority of patients 20 (28.6%) were in the age group between 60 and 69 years and males were predominant 43 (61.4%). The neoplastic lesions constituted 40 (57.1%) of all bladder lesions, among them urothelial carcinoma accounted for 38 (54.2%). Similarly, chronic cystitis 27(38.6%) was the most common non-neoplastic lesion. Conclusion: The study found that the neoplastic lesions were commonly encountered in urinary bladder lesions. Among them, lowgrade urothelial carcinoma was the most common bladder tumor. However, most of the non-neoplastic lesions were inflammatory in origin. Cystoscopy combined with histomorphological examination helps in the early detection of bladder lesions.

Abstract Background Early detection of clusters of pathogens is crucial for infection prevention and control (IPC) in hospitals. Conventional manual cluster detection is usually restricted to certain areas of the hospital and multidrug resistant organisms. Automation can increase the comprehensiveness of cluster surveillance without depleting human resources. We aimed to describe the application of an automated cluster alert system (CLAR) in the routine IPC work in a hospital. Additionally, we aimed to provide information on the clusters detected and their properties. Methods CLAR was continuously utilized during the year 2019 at Charité university hospital. CLAR analyzed microbiological and patient-related data to calculate a pathogen-baseline for every ward. Daily, this baseline was compared to data of the previous 14 days. If the baseline was exceeded, a cluster alert was generated and sent to the IPC team. From July 2019 onwards, alerts were systematically categorized as relevant or non-relevant at the discretion of the IPC physician in charge. Results In one year, CLAR detected 1,714 clusters. The median number of isolates per cluster was two. The most common cluster pathogens were Enterococcus faecium (n = 326, 19 %), Escherichia coli (n = 274, 16 %) and Enterococcus faecalis (n = 250, 15 %). The majority of clusters (n = 1,360, 79 %) comprised of susceptible organisms. For 906 alerts relevance assessment was performed, with 317 (35 %) alerts being classified as relevant. Conclusions CLAR demonstrated the capability of detecting small clusters and clusters of susceptible organisms. Future improvements must aim to reduce the number of non-relevant alerts without impeding detection of relevant clusters. Digital solutions to IPC represent a considerable potential for improved patient care. Systems such as CLAR could be adapted to other hospitals and healthcare settings, and thereby serve as a means to fulfill these potentials.

Background. Infertility is both a clinical and a public problem, affecting the life of the couple, the healthcare services, and social environment. Standard semen analysis is the surrogate measure of male fertility in clinical practice.Objective. To provide information about the relationship between semen parameters and spontaneous conception.Methods. We evaluated retrospectively 453 pregnancies that occurred among 2935 infertile couples evaluated at an infertility clinic of a tertiary-care university hospital, between 2004 and 2009.Results. Normal semen analysis was present only in 158 patients; 295 subfertile patients showed alterations in at least one seminal parameter. A reduction in all seminal parameters was observed in 41 patients. Etiological causes of male infertility were identified in 314 patients.Conclusion. Our data highlights the possibility of a spontaneous conception with semen parameters below WHO reference values. Therefore, we support the importance of defining reference values on a population of fertile men. Finally, we analyzed the related ethical issues.

Clinical Culture

Abstract Background Clinical culture results are sometimes used to estimate the burden of multidrug-resistant organisms (MDROs) in hospitals. The association between positive clinical culture results and prevalence of MDROs in the gut is incompletely understood. Methods Rectal swab or stool samples were collected daily from adult medical intensive care unit (MICU) patients and cultured for target MDROs using selective media between January 2017 and January 2018 at Rush University Medical Center, a 676-bed tertiary-care center in Chicago. Resistance mechanisms were confirmed by phenotypic methods and/or polymerase chain reaction. Clinical culture results during MICU stay were extracted from the hospital information system. Target MDROs included vancomycin-resistant Enterococci (VRE), carbapenem-resistant Enterobacteriaceae (CRE), extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL), carbapenem-resistant Pseudomonas aeruginosa (CRPA) and carbapenem-resistant Acinetobacter baumannii (CRAB). Patients with either a study or clinical culture positive for a target MDRO were analyzed. Results We collected 5,086 study samples from 1,661 unique admissions (1,419 patients) and included here data from 413 unique admissions (397 patients) with completed microbiologic analysis. Median (IQR) patient age was 65 (51–75) years and length of MICU stay was 3 (3–4) days. A total of 156 (37.8%) patients had a target MDRO detected from a study sample at any point; 57 (36.5%) patients had >1 MDRO detected. Overall prevalence of these MDROs was found to be 22.5% VRE, 6.5% CRE, 19.8% ESBL, 4.4% CRPA, and 0.7% CRAB. New MDRO acquisition was observed in 58 (14.6%) patients (figure). Once a target MDRO was detected in a study sample, 82.2% of subsequent study samples were positive for that MDRO. Only 13 (5.8%) patients had a positive clinical culture for any target MDRO during their MICU stay (table). Conclusion Clinical cultures capture only the tip of the resistance iceberg and alone are insufficient to guide MDRO-targeted prevention strategies. Universal infection prevention measures are an alternative that may be preferred in settings where overall prevalence of MDROs is moderate or high and patients may be colonized with >1 MDRO.

Introduction: The widespread use of tigecycline raises the question of increasing infection rates of Pseudomonas aeruginosa (PA) in ICUs which are not affected by this antibiotic. Objective:  The aim of this study was to determine if treatment with tigecycline is a risk factor for PA infection in ICU patients. Methodology: A retrospective and observational study was conducted at Erciyes University Hospital, Turkey, between 2008 and 2010. The Erciyes University Hospital is a 1300-bed tertiary care facility. The patients included in this study were hospitalized in four adult ICUs. Patients with PA infections (case group) were compared with patients with nosocomial infection other than PA (control group). Results: A total of 1,167 patients with any nosocomial infections were included in the study. Two hundred and seventy eight (23.8%) of the patients had PA infection during their ICU stay. Fifty nine patients (21.2%) in the case group received tigecycline before developing PA infections, which were found to be significantly more frequent than in the controls (p < 0.01). Multivariate analysis showed that risk factors for PA infection were previous tigecycline use (4 times), external ventricular shunt (4.2 times), thoracic drainage catheter (2.5 times) and tracheostomy (1.6 times). Conclusion: Our results contribute to the need for new studies to determine the safety of tigecycline use, especially for the treatment of critically ill patients. Since tigecycline seems to be an alternative for the treatment of multidrug resistant (MDR) microorganisms, rational use of this antibiotic in ICU patients is essential.

Background: The prevalence of multidrug-resistant organisms (MDROs) in acute healthcare settings is increasing worldwide. Active screening for MDROs carriers on admission permits the prompt implementation of the appropriate precautions to decrease the probability of cross transmission to other inpatients. Objective: To report the spectrum of bacterial nasal, axilla, and perianal colonization among in patients at Najah National University Hospital (NNUH) during 2018. Methods: A retrospective observational study was performed at NNUH, a tertiary-care referral university hospital in Nablus, north of Palestine, that includes medical and surgical ICUs for both adults and children from January to August 2018. Nasal, axilla, and perianal swabs were collected within the first 24 hours of admission according to hospital policy. Patients who were referred from another hospital, who were admitted to a hospital for at least 2 nights during the previous 8 months, and who are known to have an MDROs in the past were included. Swab samples were processed for isolation and identification of these multidrug-resistant strains. Transmission-based precautions were implemented if positive results were reported (ie, contact isolation) and decolonization regimens were applied according to the CDC recommendations (muporocin ointment for nasal MRSA, daily bathing with chlorhexidine 2% soap for the rest). A daily isolation list was circulated among bed managers and senior nurses and head of departments for appropriate management of beds and reallocation of patients. The antibiotic susceptibility pattern was assessed using the disc-diffusion method on Mueller–Hinton agar and a Vitek-2 system. Results: During the period of the study, 1,425 nasal swabs, 1,245 axilla swabs, and 300 perianal swabs were collected according to the inclusion criteria. Positive results were reportedin 7%, 4%, and 44% for nasal, axilla, and perianal specimens, respectively. Regarding the distribution of bacterial colonization in the nasal swab, 73% were MRSA; for the axial, 29% were Pseudomonas; and from the perianal swab, the most prevalent pathogen was ESBL (56%) (Figs. 1–3). A discrepancy between the number of nasal or axilla and perianal swabs was observed, which was mainly due to the refusal of many patients to have the sample collected by the nurse. Conclusions: Colonization of the skin and mucous membranes of inpatients with MDROs is considered a risk factor for developing future infections. Therefore, active screening for those pathogens is critical for infection prevention and control programs and patient safety in acute-care settings.Funding: NoneDisclosures: None
