RESUMEN
Low socioeconomic status (SES) is associated with a higher risk of fragility fractures, as well as higher mortality in the first-year post-fracture. The SES variables that have the greatest impact are educational level, income level, and cohabitation status. Significant disparities exist among racial and ethnic minorities in access to osteoporosis screening and treatment. In Spain, a higher risk of fractures has been described in people with a low-income level, residence in rural areas during childhood and low educational level. The civil war cohort effect is a significant risk factor for hip fracture. There is significant geographic variability in hip fracture care, although the possible impact of socioeconomic factors has not been analyzed. It would be desirable to act on socioeconomic inequalities to improve the prevention and treatment of osteoporotic fractures.

RESUMEN
PURPOSE: The aim of the present study, conducted by a working group of the Italian Association of Medical Physics (AIFM), was to define typical z-resolution values for different digital breast tomosynthesis (DBT) models to be used as a reference for quality control (QC). Currently, there are no typical values published in internationally agreed QC protocols. METHODS: To characterize the z-resolution of the DBT models, the full width at half maximum (FWHM) of the artifact spread function (ASF), a technical parameter that quantifies the signal intensity of a detail along reconstructed planes, was analyzed. Five different commercial phantoms, CIRS Model 011, CIRS Model 015, Modular DBT phantom, Pixmam 3-D, and Tomophan, were evaluated on reconstructed DBT images and 82 DBT systems (6 vendors, 9 models) in use at 39 centers in Italy were involved. RESULTS: The ASF was found to be dependent on the detail size, the DBT angular acquisition range, the reconstruction algorithm and applied image processing. In particular, a progressively greater signal spread was observed as the detail size increased and the acquisition angle decreased. However, a clear correlation between signal spread and angular range width was not observed due to the different signal reconstruction and image processing strategies implemented in the algorithms developed by the vendors studied. CONCLUSIONS: The analysis led to the identification of typical z-resolution values for different DBT model-phantom configurations that could be used as a reference during a QC program.

The public health emergency caused by the Covid-19 outbreak in March 2020 encouraged worldwide initiatives to monitor the genetic diversity and features of the SARS-CoV-2 circulating variants, mainly based on the genomic surveillance. However, due to the impossibility to carry out extensive sequencing in resource-limited hospitals, other PCR-based strategies could be applied to efficiently monitor the circulating variants without the need to greatly expand the sequencing capacity. In our case, overpassing the technical limitations inherent to a second level hospital, we were able to characterize the weekly distribution of SARS-CoV-2 by the RT-qPCR amplification patterns visualization, single nucleotide polymorphism genotyping, and sequencing of randomly selected samples. All these molecular approaches allowed us to trace the epidemiology of SARS-CoV-2 viruses circulating in Ibiza and Formentera (Balearic Islands, Spain) during the third to the sixth pandemic waves (January 2021-July 2022), in which three major lineages that were considered as VOCs (Alpha, Delta, and Omicron), and many other non-VOC variants were detected and tracked.

Introduction: The "postural control system" acts through biomechanical strategies and functional neuromuscular adaptations to maintain body balance under static and dynamic conditions. Postural stability and body weight distribution can be affected by external sensory inputs, such as different visual stimuli. Little information is available about the influence of visual receptors on stabilometric and plantar pressure parameters. The aim of this study was to analyze variability, correlations, and changes in these parameters under open- (OE) and closed-eye (CE) conditions. Methods: A total of 31 stabilometric and plantar pressure parameters were acquired in 20 young and healthy adults during baropodometric examination performed in bipedal standing under both visual conditions. Variability of parameters was evaluated via the coefficient of variation, correlation analysis via Pearson's R2, and statistical differences via the Wilcoxon test. Results: High intra-subject repeatability was found for all plantar pressure parameters and CoP-speed (CV < 40%) under OE and CE conditions, while CoP-sway area (CoPsa) and length surface function (LSF) showed larger variability (CV > 50%). Mean and peak pressures at midfoot and total foot loads showed the least number of significant correlations with other parameters under both visual conditions, whereas the arch-index and rearfoot loads showed the largest number of significant correlations. The limb side significantly affected most plantar pressure parameters. A trend of larger LSF and lower CoPsa and mean and peak pressures at the right forefoot was found under the CE condition. Discussion: The present study provides a deeper insight into the associations between postural stability and foot load. Interesting postural adaptations, particularly with respect to different visual stimuli, the effect of the dominant side, and the specific role of the midfoot in balance control were highlighted.
RESUMEN
BACKGROUND: Objective mobility measurement of Nepali prosthesis users is lacking. OBJECTIVE: The objective of this study was to cross-culturally adapt, translate and evaluate construct validity of the Prosthetic Limb Users Survey of Mobility (PLUS-M™/Nepali-12 Short Form (SF)) instrument in lower limb prosthesis users residing in Nepal. METHODOLOGY: Two forward translations, review and reconciliation, back translation, expert review, developer review to create the PLUS-M™/Nepali-12SF. Psychometric testing for internal consistency, test-retest reliability and construct validity against the Two-Minute Walk Test (2MWT) and Amputee Mobility Predictor with Prosthesis (AMPPRO) were performed on sixty-six lower limb prosthesis users. FINDINGS: The majority of populations were with transtibial amputation 45 (68%), with transfemoral amputation 15 (23%), with knee disarticulation 5 (7.5%) and with syme's amputation 1 (1.5%). The most common cause of amputation among the population was trauma and the least was tumor. Chronbach's alpha for the PLUS-M™/Nepali-12SF was 0.90, mean T-Score was 52.90, test-retest intraclass correlation coefficient (ICC) was 0.94 (95% confidence interval 0.90-0.96). Construct validity with the 2MWT was good (r = 0.62, p< 0.001) and moderately positive with the AMPPRO (r = 0.57, p< 0.001). CONCLUSION: Our research evidenced that the PLUS-M™/Nepali-12SF had excellent reproducibility. The significance of this work is that it may allow for the measurement of mobility in austere locations of Nepal.
RESUMEN
BACKGROUND: The choice of prosthetic socket interface material significantly affects user comfort and satisfaction. The Affordable Ethylene-Vinyl Acetate Roll-On (AERO) liner was created with the aim of improving functionality and streamlining the wearing process for users. OBJECTIVE: The purpose of this study was to comprehensively assess user satisfaction, comfort, and durability of the AERO liner and compare it with the common soft Pe-Lite liner. METHODOLOGY: Fourteen individuals with transtibial amputation participated in this three-month randomized crossover trial study. The Prosthesis Evaluation Questionnaire (PEQ), Expanded Socket Comfort Score (ESCS), and liner thickness measurements were used to comprehensively compare the AERO and Pe-Lite liner. FINDINGS: The AERO liner demonstrated notable improvements in prosthetic comfort and functionality over Pe-Lite liner. After three months use, there was a significant reduction in reported frustration with the AERO liner (p=0.023, r=0.604) in the PEQ subscale. Specific aspects, such as walking with the prosthesis (p=0.030, r=0.601) and odor perception (p=0.024, d=0.579), favored the use of the AERO liner. The expanded socket comfort score (ESCS) revealed significant superiority for the AERO liner "at best" (p=0.04) and "on average" (p=0.02) after one and three months, respectively. Liner thickness analysis showed significant reductions at the mid-patellar tendon location for the AERO liner at one (0.57±0.48) and three months (0.90±0.69, p=0.01) and in the posterior region after three months (0.63±0.64, p=0.05). CONCLUSION: Our study highlights the potential advantages of the AERO liner in enhancing comfort and satisfaction. Yet, durability and thinning of the liner when compared to Pe-Lite may be a concern which may eventually affect socket fit. These findings contribute to ongoing efforts to optimize prosthetic interventions and improve the quality of life of individuals with lower limb prosthesis in resource-limited environments.
RESUMEN
BACKGROUND: There is a dearth of literature evaluating the accuracy of Air Displacement Plethysmography (ADP) compared to Dual-energy X-ray Absorptiometry (DXA) for assessing body composition in individuals with lower limb amputations. Validity of ADP in persons with lower limb amputations must be established. OBJECTIVE: The objective of this study was to compare body composition in persons with lower limb amputations using the BOD POD® and DXA. METHODOLOGY: Body composition was performed on eleven lower limb prosthesis users (age 53.2±14.3 years, weight 81.9±22.3kg) using ADP and DXA with and without prosthesis. FINDINGS: Repeated measures ANOVA indicated no significant difference in body composition among and between trials, F(3,8)= 3.36, p= 0.075. There were no significant differences in Body Fat (BF) percentage with and without prostheses on the BOD POD (28.5±15.7% and 33.7±12.1%, respectively) nor the DXA (32.9±10.6% and 32.0±9.9%, respectively). Association between the BOD POD and DXA were greatest when prostheses were not worn compared to when they were worn. Bland-Altman plots indicate agreement between BOD POD® and DXA was greatest while wearing the prosthesis. CONCLUSION: This study is a first to compare total body fat percent between the BOD POD® and DXA in lower limb prosthesis users. BOD POD® report valid indices of BF%. Future work will utilize the BOD POD® in intervention studies for monitoring body composition changes across the continuum of rehabilitation.
RESUMEN
Cheeses are able to serve as suitable matrices for supplying probiotics to consumers, enabling appropriate conditions for bacteria to survive gastric transit and reach the gut, where they are assumed to promote beneficial processes. The present study aimed to evaluate the microbiological, immunological, and histological changes in the gut of Salmonella Enteritidis-challenged rats fed goat cheese supplemented with the probiotic strain Lactobacillus rhamnosus EM1107. Thirty male albino Wistar rats were randomly distributed into 5 experimental groups with 6 animals each: negative (NC) and positive (PtC) control groups, control goat cheese (CCh), goat cheese added with L. rhamnosus EM1107 (LrCh), and L. rhamnosus EM1107 only (EM1107). All animals, except NC group were challenged with Salmonella Enteritidis (109 cfu in 1 mL of saline through oral gavage). Microbial composition was assessed with high-throughput 16S rRNA sequencing by means of Illumina MiSeq (Illumina, San Diego, CA). Nuclear factor kappa B (NF-κB) from the animal cecum tissue was determined by real-time PCR and interleukins (TNF-α, IL-1ß, IL-10, and IFN-γ) by means of ELISA. Myeloperoxidase and malondialdehyde levels were determined biochemically. The administration of the L. rhamnosus EM1107 probiotic strain, either as a pure culture or added to a cheese matrix, was able to reduce Salmonella colonization in the intestinal lumen and lessen tissue damage compared with rats from PtC group. In addition, the use of cheese for the probiotic strain delivery (LrCh) was associated with a marked shift in the gut microbiota composition toward the increase of beneficial organisms such as Blautia and Lactobacillus and a reduction in NF-κB expression. These findings support our hypothesis that cheeses might be explored as functional matrices for the efficacious delivery of probiotic strains to consumers.

BACKGROUND & AIMS: In the absence of methodologically sound randomized controlled trials (RCTs), current recommendations for timing and amount of enteral nutrition (EN) in critically ill children are based on observational studies. These studies have associated achievement of a higher EN intake in critically ill children with improved outcome. Inherent to the observational design of these underlying studies, thorough insight in possible confounding factors to correct for is essential. We evaluated the associations between EN intake and 1) patient and daily clinical characteristics and 2) clinical outcomes adjusted for these patient and clinical characteristics during the first week of critical illness with a multivariable mixed model. METHODS: This secondary analysis of the multicentre PEPaNIC RCT investigated a subgroup of critically ill children with daily prospectively recorded gastrointestinal symptoms and EN intake during the first week with multivariable analyses using two-part mixed effect models, including multiple testing corrections using Holm's method. These models combined a mixed-effects logistic regression for the dichotomous outcome EN versus no EN, and a linear mixed-effects model for the patients who received any EN intake. EN intake per patient was expressed as mean daily EN as % of predicted resting energy expenditure (% of EN/REE). Model 1 included 40 fixed effect baseline patient characteristics, and daily parameters of illness severity, feeding, medication and gastrointestinal symptoms. Model 2 included these patient and daily variables as well as clinical outcomes. RESULTS: Complete data were available for 690 children. EN was provided in 503 (73%) patients with a start after a median of 2 (IQR 2-3) days and a median % of EN/REE of 38.8 (IQR 14.1-79.5) over the first week. Multivariable mixed model analyses including all patients showed that admission after gastrointestinal surgery (-49%EN/REE; p = 0.002), gastric feeding (-31% EN/REE; p < 0.001), treatment with inotropic agents (-22%EN/REE; p = 0.026) and large gastric residual volume (-64%EN/REE; p < 0.001) were independently associated with a low mean EN intake. In univariable analysis, low mean EN intake was associated with new acquired infections, hypoglycaemia, duration of PICU and hospital stay and duration of mechanical ventilation. However, after adjustment for confounders, these associations were no longer present, except for low EN and hypoglycaemia (-39%EN/REE; p = 0.018). CONCLUSIONS: Several patient and clinical characteristics during the first week of critical illness were associated with EN intake. No independent associations were found between EN intake and clinical outcomes such as mortality, new acquired infection and duration of stay. These data emphasize the necessity of adequate multivariable adjustment in nutritional support research and the need for future RCTs investigating optimal EN intake.

Objetivo: Nuestro estudio tiene como objetivo principal valorar la evolución de los niveles de esclerostina en pacientes con trasplante hepático, e investigar su relación con otros marcadores de remodelado óseo. Material y método: Estudio observacional prospectivo. Se incluyeron 83 pacientes con trasplante hepático. Se determinaron los valores de esclerostina, β-crosslaps, fosfatasa alcalina ósea, osteocalcina y proteína C reactiva la semana anterior al trasplante y posteriormente, a los 1, 3, 6 y 12 meses. Se determinaron basalmente la 25 hidroxi-vitamina D y la paratohormona. En cada revisión se evaluó la existencia de fracturas. La evolución de los marcadores respecto del valor basal se determinó mediante la prueba t-Student. Un valor de p inferior a 0,05 se consideró estadísticamente significativo. Resultados: 56 varones y 27 mujeres (edad media: 56,2±10,4 años). Los niveles basales de esclerostina (0,76±0,35 ng/ml) disminuyeron de forma significativa precozmente (0,55±0,22 ng/ml en el primer mes, p=0,034), tendencia que se mantuvo hasta los 12 meses (0,62±0,22 ng/ml, p=0,047). Al contrario, los niveles basales de osteocalcina (17±10,3 ng/ml) y β-crosslaps (0,44±0,3 ng/ml) se incrementaron significativamente a los largo del estudio; en el caso de la osteocalcina, hasta los 12 meses (37,27±26,84 ng/ml, p<0,01) y el β-crosslaps, hasta los 6 meses (0,62±0,34 ng/ml, p<0,01), con un descenso posterior (0,47±0,31 ng/ml, p=0,2). Conclusiones: Tras el trasplante hepático existe un descenso de los niveles de esclerostina, opuesto a la elevación de otros marcadores de remodelado, β-crosslaps y osteocalcina. Son necesarios más estudios para determinar si estos cambios tienen un impacto en la aparición de osteoporosis en pacientes sometidos a trasplante
Objetive:Our main objective was to evaluate the development of sclerostin levels in patients with liver transplantation,and to investigate their relationship with other bone remodeling markers.Material and method:Prospective observational study of 83 patients with liver transplantation. Sclerostin, β‐crosslaps,bone alkaline phosphatase, osteocalcin and C‐reactive protein values were determined the week before the transplantand subsequently, at 1, 3, 6 and 12 months. The hydroxy‐vitamin D and the paratohormone were determined basally. Ineach revision, the existence of fractures was evaluated. The development of the markers compared to the baseline valuewas determined by the t‐Student test. A p‐value less than 0.05 was considered statistically significant.Results:56 men and 27 women (mean age: 56.2±10.4 years). Baseline sclerostin levels (0.76±0.35 ng/ml) decreasedsignificantly early (0.55±0.22 ng/ml in the first month, p=0.034), a trend that remained until 12 months (0.62±0.22ng/ml, p=0.047). On the contrary, the basal levels of osteocalcin (17±10.3 ng/ml) and β‐crosslaps (0.44±0.3 ng/ml) in‐creased significantly throughout the study; in the case of osteocalcin, up to 12 months (37.27±26.84 ng/ml, p<0.01) andβ‐crosslaps, up to 6 months (0.62±0.34 ng/ml, p<0.01), with a subsequent decrease (0.47±0.31 ng/ml, p=0.2).Conclusions:There is a decrease in the levels of sclerostin after liver transplantation, as opposed to the elevation ofother markers of remodeling, β‐crosslaps and osteocalcin. More studies are needed to determine if these changes havean impact on the occurrence of osteoporosis in patients undergoing transplantation

Nowadays, the use of wild and culture harvest seaweed in food industry is a booming productive sector. In this context, a radiological characterization of five globally common seaweed species that were collected in arrival on Gran Canaria coast was carried out. The studied algae species were Cymopolia barbata, Lobophora variegata, Sargassum vulgare, Dictyota dichotoma and Haliptilon virgatum. Radionuclides analysed by alpha and gamma spectrometry were 238U, 234U, 235U, 210Po, 234Th, 226Ra, 210Pb, 228Th, 224Ra, 40K and 7Be. Activity concentrations, ratios, and concentration factors (CF) were determined for all samples collected. The CF in algae was higher for reactive-particle radionuclides (210Po, 234Th, 228Th and 210Pb) than for conservative ones (40K and the uranium isotopes). 210Po, 228Th and 234Th CF were one or two orders of magnitude higher than those recommended by the IAEA. L. variegata, C. barbata and S. vulgare showed a clear preference for 210Pb and 210Po, for uranium radioisotopes, and for 40K and 234Th, respectively. A dosimetry assessment due to seaweed ingestion showed considerable values of annual committed effective dose for H. virgatum (605⯱â¯19⯵Sv/y), L. variegata (574⯱â¯17⯵Sv/y) and D. dichotoma (540⯱â¯30⯵Sv/y). Hence, this study suggests that an algae radiological characterization is recommended as part of the product valorising process.

BACKGROUND: Transtibial prosthesis socket trim lines have remained fairly consistent over the past decade, and based on methods such as a supracondylar cuff suspension. However, with vacuum suspension methods, trim lines can change. OBJECTIVE: An objective of this technical note was to inform practitioners how to fabricate a socket in a better way. A step-by-step fabrication guide is provided for the prosthetist. METHODS: A unilateral transtibial amputee was selected for this technical note. We provide a detailed description of the different steps of fabrication as well as patient feedback. The fabrication involved fabrication of a vacuum socket using Pre-preg carbon fiber and anti-bacterial Ethylene-Vinyl-Acetate (EVA), as a proximal flexible brim. FINDINGS: The properties of EVA and Pre-preg carbon fiber allow for fabrication of a transtibial socket with a flexible proximal brim. The new design resulted in greater comfort and increased range of motion in the patient studied. The patient subjectively noted enhanced squatting and cycling capabilities while using the updated socket and flexible proximal brim. CONCLUSION: This technical note presented a fabrication guide for a new style of socket and preliminary patient feedback. Clinical studies evaluating functional and biomechanical effects of this new socket design are needed.
RESUMEN
Objetivo: Determinar la prevalencia de aneurisma de aorta abdominal (AAA), definido por un diámetro arterial ≥30mm, en pacientes con alto o muy alto riesgo cardiovascular (RCV) y evaluar sus características clínicas. Pacientes y métodos: Estudio observacional, transversal y multicéntrico realizado en servicios de Medicina Interna del país a varones con edad >55años y mujeres >65años que tenían un RCV alto o muy alto reclutados durante 24meses. Resultados: Se incluyeron 659 pacientes. La prevalencia de AAA fue del 8% (53 pacientes). El 76,9% fueron varones, con edad media de 71±8,7años. El análisis multivariante demostró asociación entre AAA y la edad (OR: 1,06; IC95%: 1,02-1,1; p<0,01), el sexo masculino (OR: 5,6; IC95%: 1,6-18,8; p=0,01), el tabaquismo activo (OR: 3,22; IC95%: 1,16-8,93; p=0,024) y la arteriopatía periférica (OR: 3,51; IC95%: 1,73-7,09; p<0,01), siendo la diabetes mellitus un factor protector independiente (OR: 0,41; IC95%: 0,22-0,78; p=0,06). Los pacientes con dilatación subaneurismática de la aorta (diámetro de la aorta abdominal 25-29,9mm) presentaban similares características que los pacientes con AAA. Conclusiones: La prevalencia de AAA en pacientes de alto RCV es elevada. El cribado ecográfico puede ser realizado por médicos generalistas. Pueden beneficiarse de un cribado oportunista los varones de más de 65años, con RCV elevado, especialmente si presentan tabaquismo activo o arteriopatía periférica
Background: To determine the prevalence of abdominal aortic aneurysm (AAA) (arterial diameter ≥30mm), in patients with high or very high cardiovascular risk (CVR) and to evaluate their clinical features. Patients and methods: Observational, cross-sectional and multicentric study conducted in Spanish Internal Medicine Services. We enrolled men with age >55years and women >65years who had a high or very high CVR. Results: The study included 659 patients. The prevalence of AAA was 8% (53 patients). 76.9% were male with a mean age of 71±8.7years. The multivariate analysis showed an association between AAA and age (OR: 1.06; 95%CI: 1.02-1.1; P<.01), male sex (OR: 5.6; 95%CI: 1.6-18.8; P=.01), active smoking (OR: 3.22; 95%CI: 1.16-8.93; P=.024) and peripheral arterial disease (OR: 3.51; 95%CI: 1.73-7.09; P<.01). Diabetes mellitus was an independent protective factor (OR: 0.41; 95%CI: 0.22-0.78; P=.06). Those with subaneurysmal dilatation of the abdominal aorta (diameter 25-29.9mm) presented similar features as patients with AAA. Conclusions: The prevalence of AAA in patients with high CVR is high. Ultrasound screening can be performed by general practitioners. Men >65years with elevated CVR could benefit, particularly in the presence of active smoking or peripheral arterial disease

OBJECTIVE: No study has evaluated the impact of a multifaceted intervention on the quality of the antibiotics prescribed more than 5 years later. METHODS: A total of 210 general practitioners (GP) from eight different regions of Spain were asked to participate in two registrations of respiratory tract infections (RTI) in 2008, before, and in 2009, just after a multifaceted intervention including prescriber feedback, clinical guidelines, training sessions focused on appropriate antibiotic prescribing, workshop on rapid tests and provision of these tests in the GP consultation. They were all again invited to participate in a similar registration in 2015. A new group of clinicians from the same areas who had never participated in antimicrobial stewardship courses were also invited to participate and acted as controls. RESULTS: The 121 GPs who continued the study (57.6%) and the 117 control GPs registered 22,407 RTIs. The antibiotic most commonly prescribed was amoxicillin and clavulanic acid, prescribed in 1,801 cases (8.1% of the total), followed by amoxicillin (1,372 prescriptions, 6.2%), being lower among GPs just after the intervention. The third leading antibiotic among GPs just after the intervention was penicillin V (127 cases, 3.3%) whereas macrolides ranked third in the other three groups of GPs. CONCLUSIONS: The use of first-line antibiotic for RTIs wanes over time after an intervention, but their utilisation is still significantly greater among intervened clinicians six years later compared to GPs who have never been exposed to any antimicrobial stewardship programmes.

Los pacientes ancianos con enfermedad urológica de base tienen mayor riesgo de infecciones del trato urinario por patógenos infrecuentes. Previamente se ha infraestimado la enfermedad causada por Aerococcus, pero la espectrometría de masas podría ser un método sencillo para su identificación. En este trabajo se describen 2 casos de infección urinaria por Aerococcus sanguinicola (A. sanguinicola). Se realizó un estudio descriptivo clínico-microbiológico de la presencia de A. sanguinicola produciendo infecciones urinarias. La presencia de A. sanguinicola ocurrió en pacientes ancianos con enfermedad urológica previa y con un recuento significativo en orinas obtenidas mediante sondaje vesical. La identificación fue correcta mediante espectrometría de masas. La evolución clínica fue satisfactoria mediante el uso de amoxicilina y cefuroxima. En este trabajo informamos de la capacidad patógena de A. sanguinicola. En el urocultivo, ante un recuento significativo de microorganismos alfa-hemolíticos, deberíamos descartar que se trate de A. sanguinicola antes de informar un resultado como microbiota urogenital
Elderly patients with underlying urological disease have a greater risk of urinary tract infections due to uncommon pathogens. The disease caused by Aerococcus has been underestimated, but mass spectrometry could be a simple method for identifying this pathogen. In this study, we report 2 cases of urinary tract infection by Aerococcus sanguinicola. A descriptive clinical-microbiological study was conducted on the presence of A. sanguinicola causing urinary tract infections. The presence of A. sanguinicola occurred in elderly patients with previous urological disease and a significant count in urine obtained through bladder catheterisation. Correct identification was achieved through mass spectrometry, and the clinical outcome of administering amoxicillin and cefuroxime was satisfactory. In this study, we also report the pathogenic capacity of A. sanguinicola. When there is a significant number of alpha-haemolytic microorganisms in the urine cultures, A. sanguinicola should be ruled out before reporting a result as urogenital microbiota

The multivariate analysis showed an association between AAA and age (OR: 1.06; 95%CI: 1.02-1.1; P<.01), male sex (OR: 5.6; 95%CI: 1.6-18.8; P=.01), active smoking (OR: 3.22; 95%CI: 1.16-8.93; P=.024) and peripheral arterial disease (OR: 3.51; 95%CI: 1.73-7.09; P<.01). Diabetes mellitus was an independent protective factor (OR: 0.41; 95%CI: 0.22-0.78; P=.06). Those with subaneurysmal dilatation of the abdominal aorta (diameter 25-29.9mm) presented similar features as patients with AAA. CONCLUSIONS: The prevalence of AAA in patients with high CVR is high. Ultrasound screening can be performed by general practitioners. Men >65years with elevated CVR could benefit, particularly in the presence of active smoking or peripheral arterial disease.
RESUMEN
Introducción: La biopsia prostática transrectal ecográficamente dirigida (BPTE) se asocia a complicaciones infecciosas (CI). Las CI están relacionadas con un incremento de la prevalencia de bacterias ciprofloxacino-resistentes (BCR) en la flora rectal. Estudiamos las CI ocurridas en 2 grupos. Grupo de profilaxis antibiótica «dirigida» (GPD) vs. grupo de profilaxis empírica (GPE). Evaluamos el impacto económico que supone la profilaxis antibiótica «dirigida» (PD). Material y métodos: El GPD se estudió prospectivamente (junio 2013-julio 2014). Se recogieron cultivos rectales (CR) antes de BPTE y se sembraron en medios selectivos con ciprofloxacino para determinar la presencia de BCR. Los pacientes con bacterias sensibles recibieron ciprofloxacino. Pacientes con bacterias resistentes recibieron PD según antibiograma del CR. El GPE se estudió retrospectivamente (enero 2011-junio 2009). El CR no se realizó y todos los pacientes recibieron ciprofloxacino como profilaxis. Las CI ocurridas en ambos grupos se registraron en un periodo no superior a 30 días después de BPTE (historia clínica electrónica). Resultados: Trescientos pacientes fueron sometidos a BPTE, 145 recibieron PD y 155 PE. En el GPD, 23 pacientes (15,86%) presentaron BCR en CR. Solo un paciente (0,7%) experimentó ITU. En el GPE, 26 pacientes (16,8%) experimentaron múltiples CI (incluidas 2 sepsis) (p < 0,005). El coste total estimado, incluido el manejo de las CI, fue de 57.076 € con PE vs. 4.802,33 € con PD. El coste promedio/paciente con PE fue de 368,23 € vs. 33,11 € con PD. La PD logró un ahorro total estimado de 52.273,67 €. Es necesario que 6 pacientes se sometan a PD para prevenir una CI. Conclusiones: La PD se asoció a un notable descenso de la incidencia de CI causadas por BCR y redujo los costos de atención sanitaria
Transrectal ultrasound-guided prostate biopsy (TUPB) is associated with infectious complications (ICs), which are related to a greater prevalence of ciprofloxacin-resistant bacteria (CRB) in rectal flora. We examined the ICs that occurred in 2 groups: A guided antibiotic prophylaxis (GP) group and an empiric prophylaxis (EP) group. We assessed the financial impact of GP.: Material and methods: The GP group was studied prospectively (June 2013 to July 2014). We collected rectal cultures (RCs) before the TUPB, which were seeded on selective media with ciprofloxacin to determine the presence of CRB. The patients with sensitive bacteria were administered ciprofloxacin. Patients with resistant bacteria were administered GP according to the RC antibiogram. The EP group was studied retrospectively (January 2011 to June 2009). RCs were not performed, and all patients were treated with ciprofloxacin as prophylaxis. The ICs in both groups were recorded during a period no longer than 30 days following TUPB (electronic medical history). Results: Three hundred patients underwent TUPB, 145 underwent GP, and 155 underwent EP. In the GP group, 23 patients (15.86%) presented CRB in the RCs. Only one patient (0.7%) experienced a UTI. In the EP group, 26 patients (16.8%) experienced multiple ICs (including 2 cases of sepsis) (P < .005). The estimated total cost, including the management of the ICs, was €57,076 with EP versus €4802.33 with GP. The average cost per patient with EP was € 368.23 versus €33.11 with GP. GP achieved an estimated total savings of € 52,273.67. Six patients had to undergo GP to prevent an IC. Conclusions: GP is associated with a marked decrease in the incidence of ICs caused by CRB and reduced healthcare costs
