Adding vortexing to the Maki technique provides no benefit for the diagnosis of catheter colonization or catheter-related bacteremia.

BACKGROUND: A previous study compared vortexing and Maki techniques for the diagnosis of catheter-related bloodstream infection (CRBSI), and concluded that vortexing was not superior to Maki method. AIM: To determine whether the combined use of vortexing and Maki techniques provides profitability versus the Maki technique for the diagnosis of catheter tip colonization (CTC) and CRBSI. METHODS: Observational and prospective study carried out in an Intensive Care Unit. Patients with suspected catheter-related infection (CRI) and with one central venous catheter for at least 7 days were included. The area under the curve (AUC) of the Maki technique, the vortexing technique and the combination of both techniques for the diagnosis of CTC and CRBSI were compared. RESULTS: We included 136 episodes of suspected CRI. We found 21 cases of CTC of which 10 were also CRBSI cases. Of the 21 CTC episodes, 18 (85.7%) were diagnosed by Maki technique and vortexing technique, 3 (14.3%) only by the technique of Maki, and none only by technique of vortexing. Of the 10 CRBSI episodes, 9 (90.0%) were diagnosed by the techniques of Maki and vortexing, 1 (10.0%) was diagnosed only by the technique of Maki, and none only by the technique of vortexing. We no found differences in the comparison of AUC between the technique of Maki and the combination of Maki and vortexing techniques for the diagnosis of CTC (P = 0.99) and CRBSI (P = 0.99). CONCLUSION: The novel finding of our study was that the combined use of vortexing and Maki techniques did not provide profitability to the technique of Maki alone to CRBSI diagnosis of.

Identification and antibiogram of Enterobacterales from direct urine samples using matrix assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) technology and disk-plate diffusion technique.

Identification and antibiogram of uropathogenic microorganisms from direct urine samples present a great clinical impact. Here, we present a combined procedure to determine identification (IDd) of bacteria through MALDI-TOF-MS technology and antibiogram (ATBd) using disk-plate diffusion technique, of UTI-producing Enterobacterales against the most used antibiotics. Ninety-four urine samples with presence of pyuria and Gram-negative bacilli were selected. The IDd showed a high success rate (90%). ATBd procedure showed a high correlation for tested antibiotics. This simplified, low cost and reduced work time two-step procedure significantly reduces results turnaround time and benefit the clinical management of patients with UTI.

Epidemiología y prevalencia de Mycoplasma genitalium y resistencia a azitromicina en el Área Norte de Tenerife, Islas Canarias

Introducción: La infección y resistencia antimicrobiana de Mycoplasma genitalium está infradiagnósticada en nuestra comunidad ya que no es una Enfermedad de Declaración Obligatoria y requiere técnicas de biología molecular, no siempre disponibles. Objetivo: Estudiar la epidemiología y prevalencia de M. genitalium y la tasa de resistencia frente a azitromicina en nuestra Área de Salud. Métodos: Estudio retrospectivo, desde abril de 2019 a julio de 2020, realizado en el Área de Salud del Norte de Tenerife, la cual atiende el Hospital Universitario Canarias. Para el diagnóstico de las infecciones de transmisión sexual (ITS) se utilizó la RT-PCR Allplex™ STI Essential Assay (Seegene, South Korea). Las muestras en las que se detectó M. genitalium fueron congeladas a −80°C para posteriormente realizar estudio de resistencia a azitromicina con la RT-PCR Allplex™ MG y AziR Assay (Seegene, South Korea). Resultados: Se identificaron 111/3.849 (prevalencia de 2,8%) pacientes con M. genitalium, de los cuales la mayoría, 59(53,1%) eran hombres con una mediana de 32 años (15-74) y cuyas muestras procedían principalmente de Atención Primaria: 55 (49,5%). Para la detección de resistencia a azitromicina, de los 111 pacientes solo se pudo analizar las muestras de 79, detectándose resistencia in vitro en 15(18,3%): 10 con A2059G, 4 con A2058G y 1 con ambas. La resistencia a azitromicina fue más frecuente en hombres 12 (15,8%). Discusión y Conclusiones: Con este estudio se pone de manifiesto la importancia de la prevalencia de M. genitalium en nuestro entorno, así como su alta tasa de resistencia a azitromicina por lo que se hace necesario vigilar dicha resistencia en nuestro Área de Salud para su adecuado tratamiento.

Background: Infection and antimicrobial resistance of Mycoplasma genitalium is under-diagnosed in our community as it is not a Notifiable Infectious Disease and requires for its detection molecular biology techniques, which are not always available. Aim: To study the epidemiology and prevalence of M. genitalium and the rate of resistance to azithromycin in our Health Care Area. Methods: We conducted a retrospective study from April 2019 to July 2020 in the Northern Health Care Area of Tenerife, which is attended to the Universitary Hospital Complex of the Canary Islands. The RT-PCR Allplex™ STI Essential Assay (Seegene, South Korea) to diagnose Sexually Transmitted Infections (STI) was used. Samples in which M. genitalium was detected were stored at −80°C for subsequent diagnosis of resistance to azithromycin with the RT-PCR Allplex™ MG and AziR Assay (Seegene, South Korea). Results: Of a total of 111/3,849 (2.8% prevalence) patients diagnosed with M. genitalium, 59 (53.1%) were male with a mean age of 30 (19-61) years and mainly from Primary Care 55 (49.5%). Only 79 samples of the 111 patients could be tested to detect azithromycin resistance, of which 15 (18.3%) were resistant in vitro: 10 with A2059G, 4 with A2058G and 1 with both. Azithromycin resistance was more frequent in men 12 (15.8%) and detected mainly in urine samples 6 (60%). Discussion and Conclusions: This study highlights the prevalence of M. genitalium in our setting as well as the high rate of resistance to azithromycin, making it necessary to detect resistance to azithromycin in M. genitalium for its appropriate treatment in our Health Care Area.

Risk factors for colonization by carbapenemase-producing bacteria in Spanish long-term care facilities: a multicentre point-prevalence study.

BACKGROUND: The emergence of carbapenemase-producing bacteria (CPB) has become a major public health concern. Long-term care facilities (LTCF) are potential reservoirs for multidrug-resistant micro-organisms (MDRO). However, data on CPB is limited. The study aims to determine the prevalence of MDRO and risk factors for CPB colonization among residents of LTCFs. METHODS: A point-prevalence study was conducted at 14 LTCFs in Tenerife (Spain) between October 2020 and May 2021. Nasal and rectal swabs were cultured for methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), carbapenemase-producing Enterobacterales, MDR Acinetobacter baumannii (MDR-Ab) and MDR Pseudomonas aeruginosa. Antimicrobial susceptibility testing and molecular detection of resistance genes were performed. Risk factors for colonization by carbapenemase-producing bacteria (CPB) were determined by univariate and multivariate analysis. RESULTS: A total of 760 LTCF residents were recruited. The prevalence of colonization by CPB was 9.3% (n = 71) with the following distribution: 35 (49.3%) K. pneumoniae, 26 (36.6%) MDR-Ab, 17 (23.9%) E. coli, and 1 (1.4%) C. koseri. In addition, the prevalence of colonization by MRSA was 28.1% (n = 215) and only one case of VRE was isolated. Multivariate analysis identified male sex (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.86-3.11; P = 0.01), having a high health requirement (OR, 6.32; 95% CI, 1.91-20.92; P = 0.003) and previous hospitalization (OR, 3.60; 95% CI, 1.59-8.15 P = 0.002) as independent risk factors for CPB rectal carriage. CONCLUSIONS: LTCFs are an important reservoir for MDRO, including CPB. We have identified some predictors of colonization by CPB, which enable a more targeted management of high-risk residents. Antimicrobial stewardship programmes and infection control preventive measures are needed to stop acquisition and transmission of MDRO.

Prevalence and Characterisation of Multiresistant Bacterial Strains Isolated in Pigs from the Island of Tenerife.

BACKGROUND: Antibiotic-resistant bacteria can circulate among human and animal populations through direct contact with animals, as well as via food and the environment. The purpose of this study was to examine the prevalence and characterisation of multiresistant bacteria in pig samples. METHODS: 224 samples of pig livestock were taken at the slaughterhouse on the island of Tenerife. A nasal and a rectal sample were collected from each pig. The presence of methicillin-resistant Staphylococcus aureus (MRSA), methicillin-resistant Staphylococcus coagulase-negative (MRCoNS), vancomycin-resistant Enterococcus (VRE), extended-spectrum ß-lactamase-producing Enterobacteriaceae (BLEE), carbapenemase-producing Enterobacteriaceae (CPE), and colistin-resistant Enterobacteriaceae was investigated. The resistance genes of the isolated bacteria were characterised by specific PCRs depending on the microorganism to be studied, and in vitro antimicrobial resistance was determined using the broth microdilution method (Vitek®2 system bioMérieux®, Nurtingen, Germany). RESULTS: MRSA prevalence was 73.21% (164 isolates). MRCoNS prevalence was 9.8% (22 isolates), S. sciuri being the prevalent species. Six isolates presented a 2.7% prevalence of extended-spectrum ß-lactamase-producing Escherichia coli (BLEE) in the CTX-M-1 group. No vancomycin-resistant Enterococcus (VRE), carbapenemase-producing Enterobacteriaceae (CRE), or colistin-resistant Enterobacteriaceae were isolated. CONCLUSION: we found a high presence of multiresistant bacteria, suggesting the need for increased control and surveillance of this type of strains in pig livestock and a better understanding of the possible transmission routes of these microorganisms through livestock products.

Sexual behaviour and poor hygiene are related to recent hepatitis a virus community outbreaks

OBJECTIVES: there has been a global increase in the incidence of hepatitis A infection. The aim of this study was to examine the characteristics of the increase in our region and the degree of adherence to the recommended hygienic measures after discharge from hospital. METHODS: demographic, clinical and biochemical variables were collected from patients with acute hepatitis A in our health area. The patients were grouped as follows: January 2010 to December 2016 (historical cohort) and January 2017 to October 2017 (recent cohort). A phylogenetic analysis was also performed in the recent cohort. One month after discharge, bacterial growth was evaluated by a culture of the dominant hand imprint and were compared with a control group. RESULTS: a total of 110 cases were registered with a median age of 36.3 years (range 3-89) and 77.3 % were male. The incidence was 0.82/100,000 inhabitants/year and 22.75/100,000 inhabitants/year in the historical and recent cohorts, respectively. Patients in the recent cohort were more frequently male (52.6 % vs. 82.4 %, p = 0.008) and younger (51.7 [3-89] vs. 33.4 [4-74] years, p < 0.001). In addition, 63.8 % of the recent cohort were men who had sex with other men and had unsafe sexual practices (37.5 %). Phylogenetic analysis showed a predominance of genotype A and a high frequency of the VRD 521-2016 sequence. A higher growth of enterobacteria was observed in patients with hepatitis A compared to the control group (7.3 % vs. 1.2 %, p = 0.005), despite specific hygienic measures given at discharge. CONCLUSIONS: a recent outbreak of hepatitis A in our area was related with gender, younger age and sexual practices. Hepatitis A infected subjects showed a poor adherence to hygienic measures. Our data suggests the need for policies that encourage preventive actions, particularly vaccination in this high-risk group

El servicio de urgencias hospitalario como factor de riesgo de colonización por Staphylococcus aureus resistente a meticilina de los residentes en centros de larga estancia / Hospital emergency health service care as a risk factor for methicillin-resistant Staphylococcus aureus in residents of long-term care facilities

OBJETIVOS: Los residentes de centros de larga estancia (CLE) son población de riesgo para la colonización por Staphylococcus aureus resistente a meticilina (SARM) debido a la morbilidad asociada a la edad y la alta tasa de contactos hospitalarios, especialmente en el servicio de urgencias hospitalario (SUH). El objetivo del estudio fue determinar la prevalencia y los factores asociados a la colonización por SARM en los residentes de CLE. MÉTODO: Se realizó un estudio descriptivo transversal entre abril y junio de 2014. Como criterio de inclusión se consideró ser residente de un CLE del área norte de la isla de Tenerife. Se recogieron variables clínico-epidemiológicas y muestras nasales que se sembraron en agar chromID®MRSA, que discrimina entre colonizados por SARM o no. El tipado molecular se realizó mediante electroforesis en campo pulsante. Se realizó un análisis de regresión logística sobre la variable SARM como dependiente. RESULTADOS: Se incluyeron 624 residentes. La prevalencia de SARM fue del 25,8%. Un total de 64 residentes necesitaron ser atendidos en el SUH en los tres meses previos al estudio. En el análisis multivariante se observó que ser atendido en el SUH en los tres meses previos [odss ratio (OR): 2,05 IC 95%: 1,29-3,26, p = 0,002] y la presencia de lesiones en la piel [OR: 1,65; IC 95% (1,11-2,44), p = 0,013] fueron las variables relacionadas con la colonización por SARM. El clon predominante fue ST-5 SARM-IVa (75,8%), estrechamente relacionado con la asistencia sanitaria. CONCLUSIONES: Los CLE de nuestra área constituyen un importante reservorio de SARM. Haber sido atendido en el SUH se comportó como factor predictor de colonización por SARM, por lo que es necesario de reforzar las medidas preventivas de transmisión cruzada de microorganismos multirresistentes e implantar sistemas vigilancia activa de SARM en el SUH

OBJECTIVES: Residents of long-term care facilities (LTCFs) are at risk for methicillin-resistant Staphylococcus aureus (MRSA) colonization because of age-related illnesses and high rates of hospital use, in particular, of visits to the emergency department (ED). We aimed to determine the prevalence of and risk factors for MRSA colonization in LTCF residents. METHODS: A descriptive cross-sectional study was carried out in 2014 (April-June). LTCF residents in the northern part of the island of Tenerife were eligible for enrolment. We collected clinical and epidemiologic data and took nasal swabs for culture (chromID MRSA agar) to screen for MRSA colonization. Molecular typing was established by pulsed field gel electrophoresis. MRSA colonization was the dependent variable in logistic regression analysis. RESULTS: A total of 624 residents were enrolled. MRSA was detected in 25.8%. Sixty-four of the residents had received care in a hospital ED in the 3 months prior to enrolment. Multivariant regression analysis detected 2 risk factors for MRSA colonization: hospital ED care in the last 3 months (odds ratio [OR], 2.05; 95% CI, 1.29-3.26; P=.002) and the presence of skin lesions (OR, 1.65; 95% CI, 1.11-2.44); P=.013). The health-care-associated, ST5 MRSA-IVa, was the most prevalent (75.8%). CONCLUSIONS: LTCF residents in our area are a significant reservoir of MRSA colonization. Hospital ED care was a predictor of MRSA colonization. We believe that stronger measures to prevent cross-contamination of multidrug resistant microorganisms must be implemented, along with active vigilance systems to detect MRSA in hospitals (AU)
