Risk factors for predicted refractive error after cataract surgery in clinical practice. Retrospective observational study.

OBJECTIVES: To describe the preoperative characteristics of patients undergoing cataract surgery in our hospital, to determine the final visual and refractive results and to determine the preoperative characteristics that conditioned the presence of a residual refractive error (RRE) greater than one diopter. METHODS: Retrospective analysis of cataract surgeries performed at Araba University Hospital between February 2017 and December 2019. Sociodemographic, eye comorbidity, biometric, surgical and post-surgical characteristics were collected. RESULTS: A total of 1419 patients and 1578 surgeries were included for analysis. Of these, 9.07% had preoperative legal blindness, 31.69% eye comorbidity and 4.18% had previous surgery. Overall, 95.82% of patients achieved a corrected final visual acuity (VA) ≥ 0.5 Snellen decimal and 63.12% ≥ 1, and 96.70% of patients improved VA after surgery. RRE was between ±0.5 diopters in 77.82% of patients and between ±1 diopter in 94.74%. The most prominent risk factors that conditioned the presence of RRE greater than 1 diopter were the use of ultrasonic contact biometer, a history of glaucoma surgery, the presence of white or hard cataract, and prior legal blindness. CONCLUSIONS: The visual results of cataract surgery were excellent, with 63.12% of patients obtaining corrected VA ≥ 1 and an RRE of ±1 diopter in 94.74%. Different risk factors influenced the achievement of poor refractive outcomes: preoperative conditions (previous surgeries, white/hard cataract, previous VA) and biometrics.

Objetivos: Describir las características preoperatorias de la población intervenida de cataratas en nuestro hospital, determinar los resultados visuales y refractivos finales y determinar las características previas a la intervención que condicionan la presencia de un error refractivo residual (ERR) mayor de una dioptría.MétodosEstudio retrospectivo de cirugías de catarata realizadas en el Hospital Universitario Araba, entre febrero de 2017 y diciembre de 2019. Se recogieron características sociodemográficas, de comorbilidad ocular, biométricas, quirúrgicas y postquirúrgicas.ResultadosSe incluyeron 1.419 pacientes y 1.578 cirugías para su análisis. El 9,07% presentaron ceguera legal preoperatoria, el 31,69% comorbilidad ocular y el 4,18% había sido previamente intervenido. El 95,82% de los pacientes alcanzaron una agudeza visual (AV) final corregida ≥ 0,5 Snellen decimal y el 63,12% ≥ 1. El 96,70% de los pacientes mejoraron la agudeza visual (AV) tras la intervención. El ERR estuvo entre ± 0,5 dioptrías en el 77,82% de los pacientes y entre ± 1 dioptría en el 94,74%. Los factores de riesgo más destacados que condicionan la presencia de ERR mayor de una dioptría fueron la utilización de biómetro ultrasónico de contacto, el antecedente de cirugía de glaucoma, la presencia de catarata blanca o dura y una AV previa de ceguera legal.ConclusionesLos resultados visuales de la cirugía de cataratas fueron excelentes, alcanzando el 63,12% de los pacientes una AV corregida ≥ 1 y quedando un ERR entre ± 1 dioptría en el 94,74%. Diferentes factores de riesgo influyen en la consecución de peores resultados refractivos: condiciones preoperatorias (intervención previa, catarata blanca/dura, AV previa) y biométricas (AU)

[Inpatient candiduria: etiology, susceptibility to antifungal drugs and risk factors]. / Candiduria en pacientes hospitalizados: etiología, sensibilidad a los fármacos antifúngicos y factores de riesgo.

OBJECTIVE: Candida could become the second most frequent cause of nosocomial urinary tract infection. Although Candida albicans is the most important species, others have arisen as emerging pathogens. The aim of this study was to analyze the presence of candiduria in inpatients. METHODS: We performed a retrospective study of Candida isolates from adult inpatient urocultures over five years, gathering and tabulating data on: the species; susceptibility to fluconazole, amphotericin B, and voriconazole (Vitek2, BioMerieux); presence of catheter; hospital department of origin; and patient age and sex. RESULTS: We detected 289 yeast episodes, observing an annual increase: 134 (46.4%) were non-C. albicans yeasts, with 57 (19.7%) being Candida glabrata, 37 (12.8%) Candida tropicalis, 25 (8.6%) Candida parapsilosis, and 10 (3.5%) Candida lusitaniae. Most isolates derived from catheterized (240, 83.0%) and Internal Medicine Department (118, 40.8%) patients, observing an annual increase; 152 (52.6%) isolates were from males, and the mean age was >65 years. Susceptibility to antifungals was >85%. CONCLUSIONS: Inpatient urocultures should include data on the presence of Candida, which is more prevalent in Internal Medicine Department inpatients, in those with urinary catheter, and in over 65-year-olds. Almost half of the isolates were non-C. albicans yeasts, and we recommend complete identification of the species involved.

Clinical interest of Streptococcus bovis isolates in urine.

OBJECTIVE: Streptococcus bovis includes variants related to colorectal cancer and non-urinary infections. Its role as urinary pathogen is unknown. Our objective was to assess the presence of urinary infection by S. bovis, analysing the patients and subsequent clinical course. METHODS: Observational study, with longitudinal data collection, performed at our centre between all the cultures requested between February and April 2015. Clinical course of the patients and response to treatment were analysed. RESULTS: Two thousand five hundred and twenty urine cultures were analysed, of which 831 (33%) had a significant microbial count. S. bovis was isolated in 8 patients (0.96%). In 75% of these cases the urine culture was requested because of urinary tract infection symptoms; the remaining 25% because of fever of uncertain source; during the follow-up period no evidence of cancer or endocarditis was detected. S. gallolyticus subspecie pasteurianus was the only variant observed (100%). The clinical response to initial treatment was favourable in all cases. CONCLUSIONS: S. bovis bacteriuria may have clinical significance, especially when S. gallolyticus subspecies pasteurianus is isolated in cases with underlying urinary tract disease.
