Objectives. Nowadays, the use of flow-cytometry for the screening of urine samples is extended, but appropriate cut-off points for each population group are yet to be established. The objective of this study was to evaluate the Sysmex UF-1000i® cytometer as a screening method for detection of asymptomatic bacteriuria (AB) and Group B Streptococcus (GBS) in pregnant women.
Material and methods. Urine samples obtained during pregnancy between January-July 2019 were both processed with the Sysmex UF-1000i® and also cultured. Demographic data, flow-cytometry parameters and the result of the urine culture were collected. To assess the performance of the flow-cytometer for detection of AB and GBS, receiver operating characteristic (ROC) curves for the BACT/μL variable were applied.
Results. A total of 33,687 urine samples were received, among which 1,443 (4.3%) belonged to pregnant women. Urine culture was positive in 82 (5.7%) samples, 1,295 (89.7%) were negative and 66 (4.6%) were considered contaminated. GBS was isolated in 69 (4.8%) patients and 46 (66.7%) with a microbial count below 10E4 CFU/mL. For AB detection, the cut-off point of 550 BACT/μL yielded a sensitivity of 91.5%, a negative predictive value of 99.3% and could avoid culturing 74.1% of the samples. No cut-off value could be established for GBS detection.
Conclusions. Although the Sysmex UF-1000i® system is a valid screening method for the AB detection in pregnant population, it is not useful for the identification of GBS bacteriuria in our area. Therefore, the conventional urine culture is still required during pregnancy.

Introduction. Bloodstream Infections has become in one of the priorities for the antimicrobial stewardship teams due to their high mortality and morbidity rates. Usually, the first antibiotic treatment for this pathology must be empirical, without microbiology data about the microorganism involved. For this reason, the population studies about the etiology of  bacteremia are a key factor to improve the selection of the empirical treatment, because they describe the main microorganisms associated to this pathology in each area, and this data could facilitate the selection of correct antibiotic therapy.
Material and methods. This study describes the etiology of bloodstream infections in the Southeast of Spain. The etiology of bacteremia was analysed by a retrospective review of all age-ranged patients from every public hospital in the Autonomous Community of Valencia (approximately 5,000,000 inhabitants) for five years.
Results. A total of 92,097 isolates were obtained, 44.5% of them were coagulase-negative staphylococci. Enterobacteriales was the most prevalent group and an increase in frequency was observed along the time. Streptococcus spp. were the second microorganisms more frequently isolated. Next, the most prevalent were Staphylococcus aureus and Enterococcus spp., both with a stable incidence along the study. Finally, Pseudomonas aeruginosa was the fifth microorganism more frequently solated.
Conclusions. These data constitute a useful tool that can help in the choice of empirical treatment for bloodstream infections, since the knowledge of local epidemiology is key to prescribe a fast and appropriate antibiotic therapy, aspect capital to improve survival.

JERÓNIMO JAQUETI AROCA, PAULA RAMIRO MARTÍNEZ, LAURA M MOLINA ESTEBAN, ALBA M. FERNÁNDEZ GONZÁLEZ, ISABEL GARCÍA-ARATA, SANTIAGO PRIETO MENCHERO

Objectives. Vulvovaginal candidiasis (VVC) is a common vaginal infection. Risk factors include diabetes, antibiotic use and pregnancy. Candida albicans is the most common species identified but non-C. albicans species appear to be more commonly associated with VVC in some Asian and African countries. We had studied the distribution of Candida species in Spanish and immigrants’ women residents in Spain.
Material and methods. Retrospective study of vaginal yeast cultures between 2015 and 2018.
Results. A total of 2,283 vaginal yeast cultures were collected. Candida spp. was detected in 25.7% from Spanish women and in 28.5% from immigrants (no significant differences). Immigrants have higher rates of vaginal candidiasis compared other studies in Spain. C. albicans was the most common species isolated (82.4%).
Conclusions. There were no differences in vaginal candidiasis rate between Spanish and immigrants’ women. Immigrants consulted proportionally more compared with the Spanish women.

Objective. Evaluation of the effectiveness of a standard dose of cefalozin 2 grams for surgical site infection (SSI) prevention in obese patients compared to non-obese patients. There is no still controversy surrounding which is the best dosage of this antibiotic in obese patients for surgical prophylaxis.
Material and methods. Retrospective review of men who received prophylactic cefazolin between January 1st, 2019 and June 30th, 2019 in a traumatology department of a university hospital. Patients were stratified into 2 groups: obese (≥ 100 kg and body mass index (BMI)> 30 kg / m2) and non-obese. Patients without a 90 days follow-up after surgery and/or with an active infection at the time of surgery and/or treated with immunosuppressants were excluded. Demographic data, height, real weight, smoking, diabetes, concomitant use of immunosuppressants, surgery data and presence of infection until day 90 were collected.
Results. A total of 57 patients underwent traumatic surgery with prophylactic cefazolin, 26 non-obese and 23 obese, were studied. Both groups presented statistically significant differences in weight, BMI and post-surgery use of cefazolin. No significant differences were observed in the other variables. Two obese (8.7%) and two non-obese (7.7%) patients developed SSIs after 63 days post-surgery on average, following the difference between the groups being statistically non-significant.
Conclusion. This study shows that there is no significant difference in SSI with a standard prophylactic dose of two grams of cefazolin between obese and non-obese patients.

Remdesivir, the antiviral hope against SARS-CoV-2   

JORDI REINA

Published: 1 April 2020

http://www.doi.org/10.37201/req/028.2020

On December 31, 2019 a pneumonia outbreak caused by a new coronavirus (SARS-CoV-2) was detected in the city of Wuhan (China). Due to the high capacity of diffusion and human infection it has become a new zoonotic pandemic. The absence of a vaccine has determined the search for antiviral drugs with the capacity to inhibit the replication of the new virus. Among them, remdesivir, an analogue of adenosine, is what seems to have a more promising future. This drug has shown in vitro and in animals a high capacity to block infection and viral replication with attainable concentrations in human plasma. Although all studies have been carried out with SARS-CoV and MERS-CoV, it seems that by virological and functional analogy, remdesivir is one of the few antiviral drugs with proven efficacy.However, studies and clinical trials in humans are required to know the result of their application in them.
