Reliability of a Screening Method Using Antibiotic Disks to Detect Carbapenemases in Glucose-Nonfermenting Gram-Negative Microorganisms From Clinical Samples of a Regional Hospital in Southeastern Spain.

BACKGROUND: Infections by glucose-nonfermenting gram-negative bacilli (NFGNB) pose a major public health problem due to multiresistance to beta-lactam antibiotics, especially plasmid-borne carbapenemases. Their detection by microbiology laboratories is challenging, and there is a need for easy-to-use and reliable diagnostic techniques. Our objective was to evaluate an in-house screening method to presumptively detect carbapenemases in NFGNB in a simple and clinically useful manner. METHODS: The study included 175 NFGNB isolates from urinary, respiratory, and rectal samples. In a triple assay, isolates were incubated at 37°C for 24 h on three solid-culture media: MacConkey II Agar, 5% Sheep Blood Columbia Agar and Mueller Hinton II Agar; meropenem (MEM) and cefepime (FEP) disks were employed for screening. Studies were then performed on the inhibition halo diameter, scanning effects, and the appearance of mutant colonies, which were compared with those observed using the colorimetric Neo-Rapid CARB Kit and immunochromatography (NG5-Test Carba and K-Set for OXA-23). Receiver operating characteristic curves were constructed for these data. RESULTS: Carbapenemases were expressed by 79/175 (45.1%): 19 Pseudomonas aeruginosa and 60 Acinetobacter baumannii. Optimal inhibition halo diameter cutoffs to detect this resistance on 5% sheep blood agar were as follows: 6 mm (MEM) and 6.5 mm (FEP) for P. aeruginosa (in the absence of scanning effects and mutations) and 10.5 mm (MEM) and 16 mm (FEP) for A. baumannii (even in the presence of scanning effects). CONCLUSION: The combined utilization of MEM and FEP antibiotic disks in 5% sheep blood agar, measuring their inhibition haloes, offers an effective method to predict the presence of carbapenemases as resistance mechanism in P. aeruginosa and A. baumannii.

Preliminary reading of antibiogram by microdilution for clinical isolates in urine culture.

PURPOSE: We evaluated a modification of automated antibiograms in urine cultures designed to facilitate the early interpretation of minimum inhibitory concentrations (MICs) and accelerate the targeted treatment of urinary tract infections (UTIs), METHODS: A prospective study was conducted of 309 isolates (219 Enterobacteriaceae, 75 Enterococcus spp., and 15 non-fermenting Gram-negative bacilli (NFGNB), and a retrospective study of 9 carbapenemase-producing clinical isolates from urine cultures. Colonies grown on conventional isolation plates were inoculated in MicroScan Walkaway system panels and incubated for 7 h, using a MicroScan AutoScan-4 plate reader for preliminary MIC determination by turbidimetry. Resulting antibiograms were compared with definitive antibiograms obtained after incubation for 17 h. RESULTS: Preliminary and definitive readings were concordant for 86.7% of Gram-positive cocci isolates (65/75), 61.6% of Enterobacteriaceae (135/219), and 53.3% of NFGNB. The agreement rate was greater than 90% for most antimicrobials against Gram-positive cocci (94.7% or more) and Enterobacteriaceae, (97.2% or more for 10 of 17 antibiotics) except with nitrofurantoin (89%). The agreement rate was 86.7% or more for most antibiotics against NFGNB apart from piperacillin/tazobactam, aztreonam, amikacin, and ciprofloxacin. Gram-negative bacilli showed the highest differences in MIC values between preliminary and definitive readings. CONCLUSIONS: A preliminary antibiogram reading may be useful in urine cultures to reduce the delay before targeted antibiotherapy, especially against Enterobacteriaceae and Gram-positive cocci, but not in cases of carbapenemase-producing NFGNB. Further local studies are warranted to evaluate the usefulness of this approach in relation to resistance rates.

Antibiotic resistances of Pseudomonas aeruginosa and Acinetobacter baumannii in urine cultures: experience in a hospital of Southeast Spain.

The objectives of this study were to perform a systematic review of publications between 2010 and 2021 on the antibiotic resistance of Pseudomonas aeruginosa and Acinetobacter baumannii from urinary tract infections and to analyze changes over time in hospital urine cultures from 2016 through 2021. The literature was searched, and a retrospective cross-sectional descriptive study was performed in the hospital. Out of 21 838 positive urine cultures, 3.86% were due to P. aeruginosa and 0.44% were due to A. baumannii. For P. aeruginosa, lower resistance rates were observed to virtually all tested antibiotics than were obtained in the systematic review, and the present series of hospital samples showed an in vitro resistance rate <10% to ceftazidime, cefepime, meropenem, piperacillin-tazobactam, amikacin, tobramycin, and colistin. For A. baumannii, the resistance rates to almost all antibiotics were higher in the present series than in the systematic review, being lowest to colistin (10%). Both microorganisms show reduced in vitro susceptibility to some antibiotics during the years of the COVID-19 pandemic in comparison to previous years. In our setting, both piperacillin-tazobactam and meropenem can be recommended for the empirical treatment of UTIs by P. aeruginosa, whereas only colistin can be recommended for UTIs by A. baumannii.

Aislamiento de Haemophilus no ducreyi en muestras del aparato genital de varones: relación con la clínica / Isolation of Haemophilus no ducreyi in samples from the genital tract of men: Its clinical relationship

Introducción: Con el avance de los métodos microbiológicos, cada vez es más frecuente el aislamiento de patógenos menos típicos en cuadros de infección uretral y rectal, además de los agentes etiológicos clásicos. Uno de ellos está formado por especies de Haemophilus no ducreyi (HND). El objetivo de este trabajo es describir la frecuencia, la sensibilidad antibiótica y las características clínicas de las uretritis y proctitis por HND en varones. Pacientes y métodos: Se realizó un estudio observacional descriptivo y retrospectivo, a partir de los resultados emitidos por el Laboratorio de Microbiología del Hospital Universitario Virgen de las Nieves de Granada, de los aislamientos, entre 2016 y 2019, de HND en episodios infecciosos genitales y rectales de varones adultos. Resultados: Se aisló HND en 135 (7%) episodios. La especie más frecuente fue H. parainfluenzae (34/45; 75,6%). Los síntomas más frecuentes de las proctitis fueron: tenesmo rectal (31,6%) y adenopatías (10,5%); en aquellos con uretritis, fueron disuria (71,6%), supuración uretral (46,7%) y lesiones en el glande (27%), siendo manifestaciones similares a las infecciones provocadas por los genitopatógenos habituales. Un 43% de los pacientes eran VIH positivos. Las tasas de resistencia a antibióticos de H. parainfluenzae fueron elevadas a levofloxacino, ampicilina, tetraciclina y azitromicina. Conclusión: Las especies de HND deberían tenerse en cuenta como posibles agentes etiológicos en episodios de infección uretral y rectal en varones, sobre todo en los casos con pruebas de detección negativas para agentes productores habituales de infecciones de transmisión sexual. Su detección microbiológica es fundamental para la instauración de un tratamiento efectivo dirigido. (AU)

Introduction: With the advancement of microbiological methods, the isolation of less typical pathogens in cases of urethral and rectal infection is more frequent, apart from the classic etiological agents. One of them is formed by species of Haemophilus no ducreyi (HND). The objective of this work is to describe frequency, susceptibility to antibiotics, and clinical features of HDN urethritis and proctitis in adult males. Patients and methods: This is an observational retrospective descriptive study of the results obtained by the Microbiology laboratory of the Virgen de las Nieves University Hospital on the isolates of HND in genital and rectal samples from males between 2016 and 2019. Results: HND was isolated in 135 (7%) of the genital infection episodes diagnosed in men. H. parainfluenzae was the most commonly isolated (34/45; 75.6%). The most frequent symptoms in men with proctitis were rectal tenesmus (31.6%) and lymphadenopathy (10.5%); in those with urethritis, dysuria (71.6%), urethral suppuration (46.7%) and gland lesions (27%), so differentiating it from infections caused by other genitopathogens is difficult. 43% of patients were HIV positive. Antibiotic resistance rates for H. parainfluenzae were high to quinolons, ampicillin, tetracycline and macrolides. Conclusion: HND species should be considered as possible etiologic agents in episodes of urethral and rectal infection in men, especially in cases with negative screening tests for agents that cause sexually transmitted infections (STIs). Its microbiological identification is essential for the establishment of an effective targeted treatment. (AU)

Clinical Outcomes of First-line Therapies for Advanced Non-Small Cell Lung Cancer: A Systematic Review of Trials Published Between 2010 and 2020.

OBJECTIVES: To analyze the evolution of clinical outcomes derived from clinical trials on first-line therapies for advanced or metastatic non-small cell lung cancer (NSCLC) published between 2010 and 2020, focusing on how these outcomes impact survival rates and management of patients. METHODS: A systematic review of phase III and pivotal phase II clinical trials was conducted by a structured search on Medline and Embase. A comprehensive set of variables was collected to assess their influence on survival rates. We also estimated the clinical benefit by applying the ESMO-MCBS v1.1 and extracted the authors' conclusions. RESULTS: Sixty-six studies involving 34,951 patients were included. Best survival outcomes were found for nonsquamous non-small cell lung cancer (OS and progression-free survival medians: 19.4 and 10.2 mo) and for those expressing molecular targets (OS and progression-free survival medians: 23.8 and 11.0 mo). No significant influence on survival rates was observed for industry funding and disease stage (IIIB/IV vs. IV). ESMO-MCBS v1.1 was applied in 45 positive studies and resulted in a meaningful clinical benefit score in 37.8%. Quality of life (QoL) was reported in 57.6% of the original publications and showed statistical significance favoring the experimental arm in 33.3%. Positive authors' conclusions (75.7% of trials) were based on OS and/or QoL in 34% and on surrogate endpoints in 66%. CONCLUSIONS: Extended survival times and a steady improvement in QoL have been observed. However, there were more than twice as many studies reporting positive authors' conclusions as studies meeting the ESMO threshold for meaningful clinical benefit.

Antibiotic Resistance Changes in Gram-Positive Bacteria from Urine Cultures: Development Analysis in a Health Area of South-East Spain.

This study analyzed the epidemiology and antibiotic susceptibility profile of significant bacteriuria and assessed the impact of adopting EUCAST criteria on antibiotic resistances. A systematic review was performed on publications in English or Spanish between 1 January 2010 and 30 June 2021 on the susceptibility of Gram-positive bacteria isolated in urinary samples in Europe. A retrospective descriptive study was also conducted on the results of 21,838 urine cultures with presumptive urinary tract infection (UTI) obtained during the past five years by the Department of Microbiology of the Virgen de las Nieves University Hospital (Granada, Spain). The activity of various antibiotics was determined, differentiated among various populations, and interpretations compared according to the application of EUCAST or CLSI criteria. Among 21,838 cases of significant bacteriuria, 27.69% were by Gram-positive bacteria, which were Enterococcus faecalis in 19.04% and Enterococcus faecium in 3.92%. The susceptibility profile remained stable for most antibiotics except for levofloxacin for E. faecalis and Staphylococcus aureus and nitrofurantoin for E. faecium. The resistance of Enterococcus spp. and Staphylococcus spp. to glycopeptides was exceptionally low in our setting. No significant difference in the prevalence of methicillin-resistant Staphylococcus aureus was observed between hospital (26.67%) and community (28.85%) samples. Resistances in our local setting remain stable and appear to be lower than reported in other studies. The adoption of EUCAST vs. CLSI criteria did not produce a general change in resistance rates. Findings suggest the need to revise certain empirical criteria, such as aminoglycoside synergy for Enterococcus and for community-origin S. aureus.

Follow-up of health-related quality of life and pain in a cohort of patients with rheumatoid arthritis before and after COVID-19.

BACKGROUND: The foot is one of the anatomical structures of the body most affected in rheumatoid arthritis (RA), associated with the disability of patients, even more during COVID-19. The aim of this study was to analyse whether the period of physical inactivity during COVID-19 is an influential factor on health-related quality of life and foot pain in patients with RA. METHODS: 162 patients with foot pain and RA, recruited from the Hospital Virgen de las Nieves, Granada (Spain) were included. Data was collected during two different periods: January - December 2018 in person and June - September 2021 by phone. Patients were asked to complete the Spanish adapted version of the 12-Item Short Form Survey (SF-12) and the Visual Analogue Scale (VAS). RESULTS: The results from the SF-12 questionnaires were divided between its two subscales (i.e., mental, and physical component). The physical component shows an improvement between 2018 and 2021, from 32.05 in 2018-35.18 in 2021 (p < 0.05). The opposite happened with the mental component, showing a deterioration, from 39.69 in 2018-34.48 in 2021 (p < 0.05). Regarding pain, VAS shows higher levels of pain with statistically significant differences, both in general pain (from 6 in 2018-7 in 2012) and in foot pain (from 5 to 7), (p < 0.05). CONCLUSION: Mental quality of life and pain, both general and foot pain, are influenced by the period of physical inactivity during COVID-19. LEVEL OF EVIDENCE: Level II.

Its microbiological identification is essential for the establishment of an effective targeted treatment.

Evolution of Antibiotic Resistance in Escherichia coli and Klebsiella pneumoniae from Urine Cultures.

OBJECTIVE: Determine the evolution of antibiotic resistance of symptomatic bacteriuria caused by Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) in Granada. MATERIAL AND METHOD: A descriptive retrospective study was carried out, including antibiograms of urine cultures in which microorganisms identified as E. coli and K. pneumoniae, were isolated in the Microbiology laboratory of the Hospital Universitario Virgen de las Nieves (Granada, Spain) between January 2016 and June 2021. RESULTS: E. coli was the most frequent isolate (10,048) and its resistance to ampicillin (59.45%) and ticarcillin (59.59%), and the increase to cefepime (15.07%) and amoxicillin-clavulanic acid (17.67%) is noteworthy. K. pneumoniae (2222) is notable for resistance to Fosfomycin (27.91%) and an increase to ciprofloxacin (37.79%) and amoxicillin-clavulanic acid (36.63%). Resistance is generally higher in hospitalized patients, males, and adults. CONCLUSIONS: Antibiotic resistance to the studied Enterobacteriaceae is on the rise, requiring empirical treatment targeted to the population area.

Cambios en la resistencia antibiótica en episodios de bacteriospermia sintomática: Evolución en un área de salud del sudeste español / Antibiotic resistance changes in episodes of symptomatic bacteriospermia: development in a health area of southeast Spain

Objetivo: La prostatitis crónica bacteriana (PCB) es una entidad de difícil diagnóstico clínico y tratamiento, siendo el estudio microbiológico del semen la principal prueba diagnóstica. Este estudio tuvo como objetivo determinar la etiología y la resistencia antibiótica en pacientes con bacteriospermia sintomática (BPS) en nuestro medio. Material y métodos: Se ha realizado un estudio descriptivo, transversal y retrospectivo, en un Hospital Regional del sudeste español. Los participantes fueron pacientes asistidos en las consultas del Hospital con clínica compatible con PCB entre 2016 y 2021. Se recogieron y analizaron los resultados del estudio microbiológico de la muestra de semen. Se evaluó la etiología y la tasa de resistencia antibiótica de los episodios de BPS. Resultados: El principal microorganismo detectado es Enterococcus faecalis (34,89%), seguido por Ureaplasma spp. (13,74%) y Escherichia coli (10,98%). La tasa de resistencia antibiótica de E. faecalis a las quinolonas (11%) es inferior a estudios previos, mientras que, para E. coli ha sido superior (35%). Destaca la baja tasa de resistencia que muestran E. faecalis y E. coli a fosfomicina y nitrofurantoína. Conclusiones: En las BPS las bacterias grampositivas y las atípicas se establecen como los principales agentes causales de esta entidad. Esto obliga a replantear la estrategia terapéutica utilizada, lo cual evitará el aumento en las resistencias antibióticas, las recidivas y la cronicidad de esta patología. (AU)

Background: Chronic bacterial prostatitis (CBP) is an entity of difficult clinical diagnosis and treatment, being the microbiological study of semen the main diagnostic test. This study aimed to determine the etiology and antibiotic resistance in patients with symptomatic bacteriospermia (SBP) in our environment. Material and methods: A cross-sectional and retrospective descriptive study has been carried out from a Regional Hospital of the Spanish Southeast. The participants were patients assisted in the consultations of the Hospital with clinic compatible with CBP, between 2016 and 2021. The interventions were collection and analysis of the results derived from the microbiological study of the semen sample. The main determinations were the etiology and rate of antibiotic resistance of BPS episodes are analyzed. Results: The main isolated microorganism is Enterococcus faecalis (34.89%), followed by Ureaplasma spp. (13.74%) and Escherichia coli (10.98%). The rate of antibiotic resistance of E. faecalis to quinolones (11%) is lower than previous studies, while for E. coli it has been higher (35%). The low rate of resistance shown by E. faecalis and E. coli to fosfomycin and nitrofurantoin stands out. Conclusions: In the SBP, gram-positive and atypical bacteria are established as the main causative agents of this entity. This forces us to rethink the therapeutic strategy used, which will avoid the increase in antibiotic resistance, recurrences, and chronicity of this pathology.

Resistance is generally higher in hospitalized patients, males, and adults. Conclusions: Antibiotic resistance to the studied Enterobacteriaceae is on the rise, requiring empirical treatment targeted to the population area (AU)

Antibiotic Resistances of Enterobacteriaceae with Chromosomal Ampc in Urine Cultures: Review and Experience of a Spanish Hospital.

The Enterobacteriaceae Citrobacter freundii, Enterobacter cloacae, Klebsiella aerogenes, Morganella morganii, Providencia stuartii, and Serratia marcescens (CESPM group) produce numerous urinary tract infections (UTIs) which are difficult to treat due to their high multiresistance rate. The objectives of this study were to carry out a systematic review of antibiotic resistances by UTIs and to determine changes over time in urine cultures from a reference hospital in southern Spain. The literature was searched for European data on the resistance rates of each microorganism, and a retrospective cross-sectional descriptive study was performed in samples with suspicion of UTI from patients in Virgen de las Nieves University Hospital (Granada, Spain) between 2016 and the first half of 2021. Among 21,838 positive urine cultures, 1.85% were caused by E. cloacae, 0.77% by M. Morganii, 0.65% by K. aerogenes, 0.46% by C. freundii, 0.29% by P stuartii, and 0.25% by S. marcescens. The lowest resistance rates by microorganism were: E. cloacae to amikacin (3.47%) and imipenem (5.28%); M. morganii to piperacillin-tazobactam (1.79%), cefepime (4.76%), and tobramycin (7.74%); K. aerogenes to tobramycin (3.55%), gentamicin (4.25%), trimethoprim-sulfamethoxazole (4.96%), imipenem (5.75%), and cefepime (6.43%); C. freundii to imipenem (no resistance), nitrofurantoin (1.96%), fosfomycin (2.80%), and ertapenem (6.12%); P. stuartii to cefepime (3.28%) and ceftazidime (3.28%); and S. marcescens to gentamicin (1.8%), ciprofloxacin (3.64%), cefepime (3.70%), piperacillin-tazobactam (3.70%), and trimethoprim-sulfamethoxazole (5.45%). In our setting, CESMP Enterobacteriaceae showed the lowest resistance to piperacillin-tazobactam, cefepime, imipenem, gentamicin, and colistin, which can therefore be recommended for the empirical treatment of UTIs. The COVID-19 pandemic may have had a clinical impact in relation to the increased resistance of E. cloacae and M. morgani to some antibiotics.

Presence and Relevance of Emerging Microorganisms in Clinical Genitourinary Samples.

Microorganisms responsible for genitourinary infections increasingly include species other than conventional etiological agents that are of clinical and pathogenic relevance and therapeutic interest. This cross-sectional descriptive study selected samples from clinical genitourinary episodes between January 2016 and December 2019 in which emerging microbiological agents were detected. The patients' epidemiological characteristics, clinical presentation, antibiotic treatment, and outcome were studied to identify their pathogenic role. The emerging microorganisms most frequently detected in urinary tract infections were Streptococcus bovis (58.5%) and Gardnerella spp. (23.6%) in females and S. bovis (32.3%), Aerococcus urinae (18.6%), and Corynebacterium spp. (16.9%) in males, while the most frequently detected in genital infections were S. viridans (36.4%) in females and C. glucuronolyticum (32.2%) and Gardnerella spp. (35.6%) in males. All cases in female children were produced by S. bovis. Symptomatic episodes were more frequent with Aerococcus spp. and S. bovis and the presence of leukocytosis more frequent with Aerococcus spp. Quinolones and doxycycline were most often prescribed antibiotics for genital infections and quinolones and amoxicillin-clavulanic acid for urinary infections. Urinary infection by Aerococcus spp. was more frequent in males of advanced age, Corynebacterium spp. was more frequent in permanent vesical catheter carriers, and episodes of asymptomatic bacteriuria by Gardnerella spp. were more frequent in patients with kidney transplant and chronic consumers of corticosteroid therapy. Lactobacillus spp. should be considered in urinary infections of patients of advanced age and with a previous antibiotic load. Genital infection by Gardnerella spp. was significantly associated with a history of risky sexual relations.

Calidad de vida al alta hospitalaria de pacientes con sobrepeso ingresados en servicios de medicina interna / Quality of life at discharge of patients with overweight admitted to internal medicine departments

Objetivo: Evaluar la calidad de vida (CVRS) al alta hospitalaria de pacientes con sobrepeso en los servicios de medicina interna de 4 hospitales españoles. Material y método: Estudio descriptivo transversal con los datos de pacientes con índice de masa corporal ≥25kg/m2, de ≥18 años, no diabéticos, ingresados en cuatro servicios de medicina interna a lo largo de un año. El día del ingreso se les recogió variables sociodemográficas y el Índice de Comorbilidad de Charlson [ICC] el día del alta, la CVRS (cuestionario EQ-5D-5L) y los días de hospitalización. Resultados: muestra final de 168 pacientes. Con la Escala Visual Analógica del EQ-5D-5L, los pacientes del hospital de la ciudad de Granada presentaron una mediana de puntuación de 45, y de 60 en el resto de hospitales (0=peor a 100= mejor estado de salud). En los hospitales de la ciudad de Granada, Baza, Ceuta y Motril se obtuvieron unas medianas de días de estancia de 8, 6, 9 y 8, con unas medianas de edad de 81, 71, 51 y 72 años y unas medianas en el ICC de 5, 3, 0 y 1, respectivamente. No existió correlación entre los días de hospitalización con el Índice de Comorbilidad de Charlson (Coef. -0.57, p=0.48), edad (Coef -0.09, p=0.25), ni escala EVA (Coef. -0.65, p=0.43). Conclusiones: Hay gran heterogeneidad en la CVRS y en casi todas las características estudiadas en los pacientes entre los hospitales incluidos. Los pacientes del hospital de la ciudad de Granada tienen las peores valoraciones en la CVRS, son los de más edad y tienen peor ICC. Los pacientes del hospital de Ceuta son los de menos edad y tienen mejor ICC. Recomendaciones: las intervenciones en atención primaria que tengan en cuenta la CVRS al alta hospitalaria, podría mejorar la gestión clínica y sanitaria. (AU)

Objective: To evaluate the health-related quality of life (HRQoL) at hospital discharge of patients with overweight in internal medicine departments of four Spanish hospitals. Material and Methods: Descriptive cross-sectional study of non-diabetic patients aged ≥18 years with body mass index (BMI) ≥25 Kg/m2 admitted to four internal medicine departments over a one-year period. Data were gathered on sociodemographic variables and Charlson Comorbidity Index (CCI) at admission and on HRQoL (EQ-5D-5L questionnaire) and length of hospital stay at discharge. Results: The final sample included 168 patients. The median EQ-5D-5L visual analog scale score was median of 45 in Granada hospital, and median of 60 in the rest. (0 = worst to 100 = best imaginable). Median lengths of hospital stay were 8, 6, 9, and 8 days in Granada, Baza, Ceuta, and Motril hospitals, respectively, median ages were 81, 71, 51, and 72 years, respectively, and median CCI values were 5, 3, 0, and 1, respectively. No correlation was observed between length of hospital stay and CCI (coefficient -0.57, p=0.48), age (coefficient -0.09, p=0.25), or VAS (coefficient -0.65, p=0.43). Conclusions There is a wide heterogeneity in the HRQoL and almost all studied characteristics among participating centers. Patients in the hospital in Granada city have the worst HRQoL, highest age, and worst CCI value. The patients of the Ceuta hospital have lowest age and the best CCI. Recommendations: primary care interventions that take account of the HRQoL at hospital discharge could improve clinical and health care management. (AU)

Incidence of nephrotoxicity associated with intravenous colistimethate sodium administration for the treatment of multidrug-resistant gram-negative bacterial infections.

Colistimethate sodium (CMS) is the inactive prodrug of colistin, CMS has a narrow antibacterial spectrum with concentration-dependent bactericidal activity against multidrug-resistant gram-negative bacteria, including Pseudomonas aeruginosa and Acinetobacter baumannii. This study aimed to analyze potential correlations between clinical features and the development of CMS-induced nephrotoxicity. This retrospective cohort study was conducted in a tertiary-care university hospital between 1 January 2015 and 31 December 2019. A total of 163 patients received CMS therapy. 75 patients (46%) developed nephrotoxicity attributable to colistin treatment, although only 14 patients (8.6%) discontinued treatment for this reason. 95.7% of CMS were prescribed as target therapy. Acinetobacter baumannii spp. was the most commonly identified pathogen (72.4%) followed by P. aeruginosa (19.6%). Several risk factors associated with nephrotoxicity were identified, among these were age (HR 1.033, 95%CI 1.016-1.052, p < 0.001), Charlson Index (HR 1.158, 95%CI 1.0462-1.283; p = 0.005) and baseline creatinine level (HR 1.273, 95%CI 1.071-1.514, p = 0.006). In terms of in-hospital mortality, risk factors were age (HR 2.43, 95%CI 1.021-1.065, p < 0.001); Charlson Index (HR 1.274, 95%CI 1.116-1.454, p = 0.043), higher baseline creatinine levels (HR 1.391, 95%CI 1.084-1.785, p = 0.010) and nephrotoxicity due to CMS treatment (HR 5.383, 95%CI 3.126-9.276, p < 0.001). In-hospital mortality rate were higher in patients with nephrotoxicity (log rank test p < 0.001). In conclusion, the nephrotoxicity was reported in almost half of the patients. Its complex management, continuous renal dose adjustment and monitoring creatinine levels at least every 48 h leads to a high percentage of inappropriate use and treatment failure.

Hospital Intervention to Reduce Overweight with Educational Reinforcement after Discharge: A Multicenter Randomized Clinical Trial.

INTRODUCTION: Obesity and overweight affect more than one-third of the world's population and pose a major public health problem. OBJECTIVE: To evaluate the impact of an educational intervention on dietary habits and physical exercise in patients with overweight admitted to departments of internal medicine, comprising a pre-discharge educational session with follow-up and reinforcement by telephone at 3, 6, and, 12 months post-discharge. Outcome variables were weight, systolic (SBP) and diastolic (DBP) blood pressures, health-related quality of life (HRQOL), hospital readmissions, emergency department visits, and death. METHOD: A randomized experimental study with a control group was performed in hospitalized non-diabetic adults aged ≥18 years with body mass index (BMI) ≥25 Kg/m2. RESULTS AND CONCLUSIONS: The final sample included 273 patients. At three months post-discharge, the intervention group had lower SBP and DPB and improved dietary habits (assessed using the Pardo Questionnaire) and VAS-assessed HRQOL in comparison to the control group but a worse EQ-5Q-5L-assessed HRQOL. There were no between-group differences in hospital readmissions, emergency department visits, or mortality at any time point. Both groups evidenced a progressive improvement over the three follow-up periods in weight, SBP, and dietary habits but a worsening of EQ-5D-5L-value-assessed HRQOL. DISCUSSION: The intervention group showed greater improvements over the short term, but between-group differences disappeared at 6 and 12 months. Weight loss and improvements in key outcomes were observed in both groups over the follow-up period. Further research is warranted to determine whether a minimum intervention with an educational leaflet, follow-up phone calls, and questionnaires on overweight-related healthy habits, as in the present control group, may be an equally effective strategy without specific individual educational input.

La asociación entre Fusobacterium nucleatum y el cáncer colorrectal: una revisión sistemática y metaanálisis / The association between Fusobacterium nucleatum and cancer colorectal: a systematic review and meta-analysis

IntroducciónSe desconocen los factores etiológicos exactos del cáncer colorrectal (CCR), aunque se ha intentado relacionar con factores genéticos y ambientales. La posible asociación con Fusobacterium nucleatum podría abrir posibilidades en el diagnóstico precoz.ObjetivoRevisar los estudios que analizan la asociación entre F. nucleatum y el CCR.MétodosSe utilizaron las publicaciones disponibles en la base de datos MEDLINE PubMed hasta el día 1 de enero de 2020, que incluían los términos «cáncer colorrectal» y «Fusobacterium nucleatum». Se realizó un metaanálisis con el software Stata.ResultadosUn total de 57 artículos fueron incluidos en la revisión sistemática. El metaanálisis indicó una mayor presencia de F. nucleatum en muestras de tejido tumoral de CCR, con respecto a muestras control de tejido sano, con una odds ratio de 4,558 (IC 95%: 3,312-6,272), y cuando se utilizaron muestras control de adenomas colorrectales, con una odds ratio de 3,244 (IC 95%: 2,359-4,462).ConclusiónHay una mayor presencia de F. nucleatum en el CCR. Sin embargo, se necesitan estudios que demuestren esta relación.

IntroductionThe etiological factors of colorectal cancer (CRC) are not precisely known, although genetic and environmental factors have been implicated. A possible association with Fusobacterium nucleatum may provide opportunities for an early diagnosis.ObjectiveTo review studies that address the association between F. nucleatum and CRC.MethodsThe MEDLINE PubMed database was searched using the terms «colorectal cancer» and «Fusobacterium nucleatum», retrieving publications published up to January 1 2020. Stata software was used for a meta-analysis.ResultsThe systematic review included 57 articles. Meta-analysis results indicated a more frequent presence of F. nucleatum in CRC tumor tissue samples in comparison to control samples of healthy tissue, with an odds ratio of 4.558 (95% CI: 3.312-6.272), and in comparison, to control samples of colorectal adenomas, with an odds ratio of 3.244 (95% CI: 2.359-4.462).ConclusionThere is a more frequent presence of F. nucleatum in the CRC. However, further studies are needed to verify this relationship.

Insomnia Symptoms, Sleep Hygiene, Mental Health, and Academic Performance in Spanish University Students: A Cross-Sectional Study.

BACKGROUND: Insomnia has been associated with decreased academic performance and unhealthy behaviors in university students. Although many studies have analyzed sleep phenomenology among this population, only few have focused on insomnia and its related variables. In addition, such studies do not always include a clinical interview or a specific and validated instrument for measuring insomnia. This study aimed to explore the prevalence of insomnia symptoms and the relationship between insomnia and health habits, mental health, and academic performance in a large university student sample. METHODS: Five hundred and eighty-two students were recruited from the University of Granada, Spain. Data were collected through an online survey with questions on sociodemographic and academic data and health habits as well as the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Sleep Hygiene Index, and Sleepiness, Depression, Anxiety, and Stress Scales. A multiple regression analysis explored the relationship between academic performance, health habits, mood state, and insomnia symptoms. RESULTS: The prevalence of students with symptoms of insomnia was high (39.7%). A multiple logistic regression analysis revealed that depression, sleep hygiene, stress and anxiety were significant predictors of insomnia symptoms. Multivariate analyses revealed that subjective insomnia symptoms, sleep efficiency, and depression were significantly correlated with academic performance in a dependent way. CONCLUSIONS: In university students, anxiety, stress, and poor sleep hygiene are risk factors for insomnia, which plays an important role in academic performance. Promoting sleep and mental health could be a potentially effective way to improve their academic performance.

Emerging Presence of Culturable Microorganisms in Clinical Samples of the Genitourinary System: Systematic Review and Experience in Specialized Care of a Regional Hospital.

The detection of emerging pathogens responsible for genitourinary infections has increased with technological advances. We conducted a systematic review of publications on the involvement of these microorganisms in genitourinary samples, and we also investigated their presence and antibiotic susceptibility in samples from patients at our regional hospital (Granada, Spain). The MEDLINE database was searched up to 31 December 2020, and a cross-sectional descriptive study was performed of results obtained in urine samples and genital exudates from January 2016 through December 2019. The review highlighted the frequent involvement of Neisseria meningitidis in genital infections, while the data on other microorganisms were consistent with findings in our patient series. The emerging microorganisms most often responsible for urinary tract infections were Streptococcus bovis (58.5%) and Gardnerella vaginalis (23.6%) in females, and S. bovis (32.3%), Aerococcus urinae (18.6%), and Corynebacterium spp. (16.9%) in males; those most frequently reported in genital infections were S. viridans (36.4%) in females and C. glucuronolyticum (32.2%) and G. vaginalis (35.6%) in males. In general, emerging pathogens are resistant to conventional antibiotics such as penicillin. However, there has also been an increase in beta-lactam resistance by the S. bovis group and Corynebacterium spp. The systematic review showed that emerging microorganisms are responsible for only a small percentage of genitourinary infections but are of major clinical interest, with a predominance of the S. bovis group, G. vaginalis, Lactobacillus spp., Aerococcus spp., and Corynebacterium spp. in urine samples and of G. vaginalis and C. glucuronolyticum in genital samples. Given the increasing resistance to antibiotics empirically prescribed in patients with genitourinary infections, it is recommended to create an antibiogram in all cases.
