Differences in intraoperative and surgical outcomes between normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs) and hypertensive PPGLs: results from the PHEO-RISK STUDY.

PURPOSE: To compare the intraoperative and surgical outcomes of normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs), hypertensive PPGLs and non-PPGL adrenal lesions. METHODS: This a retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. A control group of histologically confirmed adrenocortical adenomas (non-PPGL group) was selected to compare intraoperative and surgical outcomes with of the normotensive PPGLs. RESULTS: Two hundred and ninety-six surgeries performed in 289 patients with PPGLs were included. Before surgery, 209 patients were classified as hypertensive PPGLs (70.6%) and 87 as normotensive PPGLs. A higher proportion of normotensive PPGLs than hypertensive PPGLs did not receive alpha presurgical blockade (P = 0.009). When we only considered those patients who received presurgical alpha blockers (200 hypertensive PPGLs and 76 normotensive PPGLs), hypertensive PPGLs had a threefold higher risk of intraoperative hypertensive crisis (OR 3.0 [95% 1.3-7.0]) and of hypotensive episodes (OR 2.9 [95% CI 1.2-6.7]) than normotensive PPGLs. When we compared normotensive PPGLs (n = 76) and non-PPGLs (n = 58), normotensive PPGLs had a fivefold higher risk of intraoperative complications (OR 5.3 [95% CI 1.9-14.9]) and a six times higher risk of postoperative complications (OR 6.1 [95% CI 1.7-21.6]) than non-PPGLs. CONCLUSION: Although the risk of intraoperative hypertensive and hypotensive episodes in normotensive PPGLs is significantly lower than in hypertensive PPGLs, normotensive PPGLs have a greater risk of intraoperative and postoperative complications than non-PPGL adrenal lesions. Therefore, it is recommended to follow the standard of care for presurgical and anesthetic management of PPGLs also in normotensive PPGLs.

Prevalence, risk factors and evolution of diabetes mellitus after treatment in primary aldosteronism. Results from the SPAIN-ALDO registry.

PURPOSE: To evaluate the prevalence, risk factors and evolution of diabetes mellitus (DM) after targeted treatment in patients with primary aldosteronism (PA). METHODS: A retrospective multicenter study of PA patients in follow-up at 27 Spanish tertiary hospitals (SPAIN-ALDO Register). RESULTS: Overall, 646 patients with PA were included. At diagnosis, 21.2% (n = 137) had DM and 67% of them had HbA1c levels < 7%. In multivariate analysis, family history of DM (OR 4.00 [1.68-9.53]), the coexistence of dyslipidemia (OR 3.57 [1.51-8.43]) and advanced age (OR 1.04 per year of increase [1.00-1.09]) were identified as independent predictive factors of DM. Diabetic patients were on beta blockers (46.7% (n = 64) vs. 27.5% (n = 140), P < 0.001) and diuretics (51.1% (n = 70) vs. 33.2% (n = 169), p < 0.001) more frequently than non-diabetics. After a median follow-up of 22 months [IQR 7.5-63.0], 6.9% of patients developed DM, with no difference between those undergoing adrenalectomy and those treated medically (HR 1.07 [0.49-2.36], p = 0.866). There was also no significant difference in the evolution of glycemic control between DM patients who underwent surgery and those medically treated (p > 0.05). CONCLUSION: DM affects about one quarter of patients with PA and the risk factors for its development are common to those of the general population. Medical and surgical treatment provides similar benefit in glycemic control in patients with PA and DM.

B Cell Receptor Genes Associated With Tolerance Identify a Cohort of Immunosuppressed Patients With Improved Renal Allograft Graft Function.

We previously reported that two B cell receptor genes, IGKV1D-13 and IGKV4-1, were associated with tolerance following kidney transplantation. To assess the potential utility of this "signature," we conducted a prospective, multicenter study to determine the frequency of patients predicted tolerant within a cohort of patients deemed to be candidates for immunosuppressive minimization. At any single time point, 25-30% of patients were predicted to be tolerant, while 13.7% consistently displayed the tolerance "signature" over the 2-year study. We also examined the relationship of the presence of the tolerance "signature" on drug use and graft function. Contrary to expectations, the frequency of predicted tolerance was increased in patients receiving tacrolimus and reduced in those receiving corticosteroids, mycophenolate mofetil, or Thymoglobulin as induction. Surprisingly, patients consistently predicted to be tolerant displayed a statistically and clinically significant improvement in estimated glomerular filtration rate that increased over time following transplantation. These findings indicate that the frequency of patients consistently predicted to be tolerant is sufficiently high to be clinically relevant and confirm recent findings by others that immunosuppressive agents impact putative biomarkers of tolerance. The association of a B cell-based "signature" with graft function suggests that B cells may contribute to the function/survival of transplanted kidneys.

Infectious encephalitis: utility of a rational approach to aetiological diagnosis in daily clinical practice.

In this study we attempt to assess the utility of a simplified step-wise diagnostic algorithm to determinate the aetiology of encephalitis in daily clinical practice and to describe the main causes in our setting. This was a prospective cohort study of all consecutive cases of encephalitis in adult patients diagnosed between January 2010 and March 2015 at the University Hospital Vall d'Hebron in Barcelona, Spain. The aetiological study was carried out following the proposed step-wise algorithm. The proportion of aetiological diagnoses achieved in each step was analysed. Data from 97 patients with encephalitis were assessed. Following a simplified step-wise algorithm, a definite diagnosis was made in the first step in 53 patients (55 %) and in 12 additional cases (12 %) in the second step. Overall, a definite or probable aetiological diagnosis was achieved in 78 % of the cases. Herpes virus, L. monocytogenes and M. tuberculosis were the leading causative agents demonstrated, whereas less frequent aetiologies were observed, mainly in immunosuppressed patients. The overall related mortality was 13.4 %. According to our experience, the leading and treatable causes of encephalitis can be identified in a first diagnostic step with limited microbiological studies. L. monocytogenes treatment should be considered on arrival in some patients. Additional diagnostic effort should be made in immunosuppressed patients.

Longitudinal studies of a B cell-derived signature of tolerance in renal transplant recipients.

Biomarkers of transplant tolerance would enhance the safety and feasibility of clinical tolerance trials and potentially facilitate management of patients receiving immunosuppression. To this end, we examined blood from spontaneously tolerant renal transplant recipients and patients enrolled in two interventional tolerance trials using flow cytometry and gene expression profiling. Using a previously reported tolerant cohort as well as newly identified tolerant patients, we confirmed our previous finding that tolerance was associated with increased expression of B cell-associated genes relative to immunosuppressed patients. This was not accounted for merely by an increase in total B cell numbers, but was associated with the increased frequencies of transitional and naïve B cells. Moreover, serial measurements of gene expression demonstrated that this pattern persisted over several years, although patients receiving immunosuppression also displayed an increase in the two most dominant tolerance-related B cell genes, IGKV1D-13 and IGLL-1, over time. Importantly, patients rendered tolerant via induction of transient mixed chimerism, and those weaned to minimal immunosuppression, showed similar increases in IGKV1D-13 as did spontaneously tolerant individuals. Collectively, these findings support the notion that alterations in B cells may be a common theme for tolerant kidney transplant recipients, and that it is a useful monitoring tool in prospective trials.

Effects of region of birth, educational level and age on late presentation among men who have sex with men newly diagnosed with HIV in a network of STI/HIV counselling and testing clinics in Spain.

This paper analyses late presentation (LP) of HIV infection, and its determinants, among men who have sex with men (MSM) in Spain, newly diagnosed with HIV (2003-2011) in 15 sexually transmitted infection/HIV counselling and testing clinics. LP was defined as <350 CD4 cells/µL or AIDS. In total, 3,081 MSM were included (2,499 having CD4/AIDS); overall LP was 25.3%. LP was higher in men older than 34 years, those not previously HIV-tested (adjusted odds ratio (aOR):3.1; 95% confidence intervals (CI):2.3-4.2) , and those tested > 12 months before diagnosis (12-24 months (aOR:1.4; 95% CI:1.0-2.0); > 24 months (aOR:2.2; 95% CI:1.7-3.0)). LP was less likely in MSM reporting a known HIV-infected partner as infection source or symptoms compatible with acute retroviral syndrome. 'Region of birth' interacted with 'educational level' and 'steady partner as infection source': only African and Latin-American MSM with low educational level were more likely to present late; Latin-American men attributing their infection to steady partner, but no other MSM, had LP more frequently. In Spain, HIV testing among MSM should be promoted, especially those > 34 years old and migrants with low educational level. The current recommendation that MSM be tested at least once a year is appropriate.

Trends in HIV testing, prevalence among first-time testers, and incidence in most-at-risk populations in Spain: the EPI-VIH Study, 2000 to 2009.

During 2000 to 2009, data on people undergoing HIV testing and on those newly diagnosed with HIV were collected in a network of 20 Spanish clinics specialising in sexually transmitted infections and/or HIV testing and counselling. The number of tests performed, overall and disaggregated by different variables, was obtained. HIV prevalence among first-time testers and HIV incidence among repeat testers were calculated. To evaluate trends, joinpoint regression models were fitted. In total, 236,939 HIV tests were performed for 165,745 individuals. Overall HIV prevalence among persons seeking HIV testing was 2.5% (95% CI: 2.4 to 2.6). Prevalence was highest in male sex workers who had sex with other men (19.0% (95% CI: 16.7 to 21.4)) and was lowest in female sex workers (0.8% (95% CI: 0.7 to 0.9)). Significant trends in prevalence were observed in men who have sex with men (MSM) (increasing) and heterosexual individuals (decreasing). The incidence analysis included 30,679 persons, 64,104 person-years (py) of follow-up and 642 seroconversions. The overall incidence rate (IR) was 1.0/100 py (95% CI: 0.9/100 to 1.1/100). Incidence was significantly higher in men and transgender females than in women (1.8/100 py (95% CI: 1.6 to 1.9), 1.2/100 py (95% CI: 0.5 to 2.8) and 0.1/100 py (95% CI: 0.09 to 0.2) respectively) and increased with age until 35­39 years. IRs in MSM and people who inject drugs were significantly greater than in heterosexual individuals (2.5/100 py (95% CI: 2.3 to 2.7), 1.6/100 py (95% CI: 1.1 to 2.2) and 0.1/100 py (95% CI: 0.09 to 0.2) respectively), and an upward trend was observed in MSM. Our results call for HIV prevention to be reinforced in MSM and transgender women in Spain.

Cumulative morbidity of ureteroscopy for upper tract urothelial carcinoma.

OBJECTIVE: To assess complications after ureteroscopy (URS) for upper tract urothelial carcinoma (UTUC) management and to assess its postoperative cumulative morbidity burden using the Comprehensive Complication Index (CCI). MATERIALS AND METHODS: Single center retrospective study including patients submitted to URS for UTUC suspicion. URSs were both diagnostic and operative. Postoperative complications were recorded according to the EAU Guidelines and graded according to Clavien-Dindo Classification (CDC). The cumulative postoperative morbidity burden developed by patients experiencing multiple events was assessed using the CCI. Multivariable logistic regression (MLR) analyses identified factors independently associated with the development of any grade and major postoperative complications. RESULTS: Overall, 360 patients with UTUC suspicion were included with a total of 575 URSs performed. The cumulative number of all postoperative complications recorded was 111. In 86 (15%) procedures, patients experienced at least one postoperative complication, while 25 (4.3%) experienced more than one complication. Of these, 16 (14%) were severe (CDC ≥ IIIa). The most frequent type of complications were urinary (34%), bleeding (30%) and infectious (30%). The higher the CDC grade, the higher the median CCI, with a statistically significant increase in median CCI from CDC II to major complications. Patients who experienced intraoperative complications were at higher risk of developing any grade and major postoperative complications at MLR. CONCLUSIONS: Complications after ureteroscopy for UTUC are relatively uncommon events. Patients who experience intraoperative complications are at higher risk of developing postoperative complications. The comprehensive complication index appeared more representative of the cumulative postoperative morbidity rather than the Clavien-Dindo classification.

Robot-assisted vs. open radical cystectomy: systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: Several randomized controlled trials (RCTs) have been launched in the last decade to examine the surgical safety and oncological efficacy of robot-assisted (RARC) vs open radical cystectomy (ORC) for patients with bladder cancer. The aim of the study was to perform a systematic review and meta-analysis of RCTs to compare the perioperative and oncological outcomes of RARC vs ORC. METHODS: A literature search was conducted through July 2022 using PubMed/Medline, Embase, and Web of Science databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. The outcomes were intraoperative, postoperative, and oncological outcomes of RARC vs ORC. RESULTS: A total of eight RCTs comprising 1,024 patients met our inclusion criteria. RARC was associated with longer operative time (mean 92.34min, 95% CI 83.83-100.84, p<0.001) and lower blood transfusion rate (Odds ratio [OR] 0.43, 95% CI 0.30-0.61, p<0.001). No differences emerged in terms of 90-day overall (p=0.28) and major (p=0.57) complications, length of stay (p=0.18), bowel recovery (p=0.67), health-related quality of life (p=0.86), disease recurrence (p=0.77) and progression (p=0.49) between the two approaches. The main limitation is represented by the low number of patients included in half of RCTs included. CONCLUSIONS: This study supports that RARC is not inferior to ORC in terms of surgical safety and oncological outcomes. The benefit of RARC in terms of lower blood transfusion rate need to be balanced with the cost related to the procedure.

[Ability of qSOFA1-lactate to predict 30-day mortality in patients seen for infection in the Emergency Department]. / Capacidad del qSOFA1-lactato para predecir mortalidad a 30 días en los pacientes atendidos por infección en urgencias.

OBJECTIVE: To evaluate lactate and the Quick Sepsis-Related Organ Failure Assessment (qSOFA) and compare their ability to predict 30-day mortality in patients treated for infection in emergency departments (ED). METHODS: Prospective multicenter observational cohort study. We enrolled a convenience sample of patients aged 18 years or older attended in 71 Spanish ED from October 1, 2019, to March 31, 2020. Each model's predictive power was analyzed with the area under the receiver operating characteristic curve (AUC), and its values of sensitivity (Se), specificity (Sp), positive predictive value (PPV) and negative (NPV). RESULTS: A total of 4439 patients with a mean (SD) age of 18 years were studied; 2648 (59.7%) were men and 459 (10.3%) died within 30 days. For 30-day mortality, the AUC-COR obtained with the qSOFA = 1 model plus 2 mmol/l lactate was 0.66 (95% CI, 0.63-0.69) with Se: 68%, Es: 70% and NPV:92%, while qSOFA = 1 obtained AUC-COR of 0.52 (95% CI, 0.49-0.55) with a Se:42%, Es:64% and NPV:90%. CONCLUSIONS: To predict 30-day mortality in patients presenting to the ED due to an episode of infection, the qSOFA =1 + lactate≥2 mmol/L model significantly improves the predictive power achieved individually by qSOFA1 and becomes very similar to qSOFA≥2.

Healthcare workers' perception of the usefulness of a healthcare ethics consultation service.

BACKGROUND AND OBJECTIVE: Clinical ethics consultation services (CEC) have arisen from Healthcare Ethics Committees (HEC) to address ethical conflicts in real-time. Our aim was to determine the perception of usefulness of a CEC service among healthcare workers one year after its creation as well as to assess changes in trends in the use of the CEC and HEC between 2015 and 2021. MATERIALS AND METHODS: This observational, cross-sectional study was based on a standardized survey of healthcare workers at an urban tertiary care hospital. The results were also compared to those from an identical survey conducted in the same population in 2015. RESULTS: A total of 213 professionals participated (mean age 44 ± 11 years, 69% women). The professionals were more familiar with the HEC than the CEC service (94% vs 61%; p < 0.001). Forty-five individuals (21%) had consulted the CEC since its implementation; 95% of them found the consultation useful. Physicians knew about and used the CEC more than other groups of professionals. The degree of knowledge of the HEC increased significantly by 2021 compared to 2015 (94% v. 76%; p < 0.001). Some areas for improvement identified were the need for greater dissemination of the service, guaranteeing institutional resources to maintain the service, and encouraging greater participation from different professional groups. CONCLUSIONS: Knowledge of the institutional HEC and CEC services has increased in recent years among healthcare workers, who considered the CEC service to be useful for addressing ethical conflicts in daily practice.

Usefulness of the 5MPB-Toledo model to predict bacteremia in patients with urinary tract infections in the emergency department.

OBJECTIVE: To analyze the usefulness of a new predictive model of bacteremia (5MPB-Toledo) in patients treated for urinary tract infection (UTI) in the emergency department (ED). METHODS: Prospective and multicenter observational cohort study of the blood cultures (BC) ordered for patients with UTIs in 65 Spanish ED from November 1, 2019, to March 31, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC). The diagnostic performance was calculated with the chosen cut-off point for sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: A total of 1,499 blood cultures were evaluated. True cases of bacteremia were confirmed in 277 (18.5%). The remaining 1,222 cultures (81.5%) were negative. Ninety-four (6.3%) were considered contaminated. The model's area under the ROC curve was 0.937 (95% CI, 0.926-0.949). The prognostic performance with a model's cut-off value of ≥5 points achieved 97.47% (95% CI, 94.64-98.89) sensitivity, 76.68% (95% CI, 74.18-79.00) specificity, 48.65% (95% CI, 44.42-52.89) positive predictive value and 99.26% (95% CI, 98.41-99.67) negative predictive value. CONCLUSION: The 5MPB-Toledo score is useful for predicting bacteremia in patients with UTIs who visit the ED.

Description of the experience of a clinical ethics consultation service from 2019 to 2021.

INTRODUCTION: Clinical ethics consultation services (CEC) are useful model for ethical counselling, albeit with scarce implementation in European countries. This article shares the experience of one of the first ethics consultation services in Spain. MATERIALS AND METHODS: This work is a retrospective, observational study of all consultations received by the CEC service at La Princesa University Hospital (Madrid, Spain) from September 1, 2019 to August 31, 2021. The demographic, logistic, and ethical variables of the cases were analyzed. RESULTS: A total of 63 cases were analyzed in which a total of 124 ethical conflicts were identified. Forty-one percent of the cases (n = 26) were emergency consultations and 38% (n = 24) were preferential inquiries. An initial evaluation was performed with 24 h in 50 cases (79%). The department that consulted most often was the Intensive Care Unit (9; 14%). The preferred contact methods were via pager (36; 57%), the electronic medical record system (13; 21%), or direct conversations with consulting team (7; 11%). The most common ethical conflicts were those related to the adequacy of treatment measures (24; 19%), refusal of treatment (19; 15%), communication with the patient or his/her family (29; 23%), or the patient's capacity (13; 11%). CONCLUSION: CEC services provide quick, efficient assistance for resolving ethical problems in daily practice. Their implementation in Spain is feasible.

Genetic variants of antioxidant enzymes and environmental exposures as molecular biomarkers associated with the risk and aggressiveness of bladder cancer.

Bladder cancer (BC) is one of the top 10 most common tumours worldwide; however, no molecular markers are currently available for tumour management and follow-up. BC could benefit from molecular biomarkers in environmental disease, which provide mechanistic understanding of individual susceptibility to exposure-related cancers and allow characterizing genetic alterations in the molecular pathway for malignancy. This case-control study performed a molecular analysis in 99 BC and 125 controls. Buccal swabs were collected to assess SNPs in eleven genes coding for xenobiotic detoxification enzymes, cellular antioxidant defences, and hormone synthesis and signalling (NAT2 (rs1801280), GPX1 (rs1050450 and rs17650792), TXNRD1 (rs7310505), PRDX3 (rs3740562), PON1 (rs662), SOD1 (rs10432782), SOD2 (rs4880), CAT (rs1001179), CYP17A1 (rs743572) and ESR1 (rs746432)). A structured questionnaire was administered to study participants to assess environmental and dietary chemical exposures. Several miRNAs associated with BC and detoxification/antioxidant pathways were analysed in a subsample of the study population, including miR-93-5p, miR-221-3p, miR-126, miR-27a-3p, miR-193b, and miR-193a-5p. Levels of selected environmental pollutants (polycyclic aromatic hydrocarbons and endocrine disrupting chemicals) were determined in urine from a subsample of BC cases and controls. We found that CYP17A1, CAT, SOD1, ESR1, PON1, and GPX1 (rs17650792) were associated with BC risk. Furthermore, exposure to smoke and/or dust, and alcohol intake were identified as risk factors for BC. Increased urinary levels of benzo[a]pyrene and bisphenol A were observed in BC patients relative to controls, along with an increased expression of miR-193b, miR-27a and miR-93-5p in BC. Nevertheless, further studies with a larger sample size are warranted to confirm these exploratory results. This study also shows that the combination of genetic markers (PON1 and CYP17A1) and miRNA (miR-221-3p and miR-93-5p) open a new scenario in the use of non-invasive biomarkers in the stratification of BC to guide personalized medicine, which is extremely urged in the current clinical setting.

[Translated article] Implementation of a rapid recovery protocol in total knee arthroplasty. A randomised controlled trial.

BACKGROUND: Rapid recovery (RP) in total knee arthroplasty may increase the functionality while reducing costs. The aim of this study is to prove the benefits of a rapid recovery programme compared to our classic protocol. PATIENTS AND METHODS: We performed a RCT (NCT03823573) in patients undergoing otal knee arthroplasty. Intervention group (RP protocol) received local infiltration of levo-bupivacaine in the periarticular tissue and supervized ambulation 4-6h after surgery. Control (C) group received a femoral nerve block with levo-bupivacaine, while a drain was used. Ambulation after its removal. All the patients completed an Oxford Knee Score prior to surgery and 6 months after discharge. An ecodoppler to assess the presence of deep vein thrombosis was made 1 month after discharge. Minimum follow-up was of 6 months. RESULTS: A total of 175 patients were included in the trial (92 patients in the control group, 83 patients in the RP group). There were no differences in sex, age, implanted prosthesis, haemoglobin drop, need for transfusion, range of motion on discharge (C: 82.6°, RP: 85°) and at the end of the follow-up (C: 105.1, RP: 106.6), Oxford knee score improvement (C: 17.5 points; RP: 19.3 points), patient satisfaction or re-admissions at the emergency department (C: 7.6%; RP: 10.8%). Significancy was found on time of ischaemia (C: 81.29min; RP: 85.35min; p=.03), need for morphine shots (C: 19.7%; RP: 38.6%; p=.007), hospital stay (C: 3.84 days; RP: 2.54 days, p<.0001) and time until ambulation (C: 2.46 days; RP: 0.23 days; p<.0001). CONCLUSION: Rapid recovery protocols can reduce hospital stay without increasing complications or need for re-admission.

[Influenza and cardiorespiratory events: a clinical-epidemiological review with a multidisciplinary point of view]. / Gripe y eventos cardiorrespiratorios: una revisión clínico-epidemiológica multidisciplinar.

There is accumulating evidence showing that influenza infection and cardiorespiratory diseases are closely associated. Influenza has been described as a triggering factor capable of both exacerbate underlying chronic diseases as well as inducing the appearance of new respiratory and cardiovascular events. Consequently, influenza infection and its associated comorbidity have a significant impact on the health system. In this document, we extensively reviewed the current literature to describe the most relevant data on the relationship between influenza infection and cardiorespiratory diseases. Likewise, we analyzed the possible pathophysiological mechanisms explaining the connection between influenza infection and cardiac and respiratory events. Finally, reviewed data has been put into perspective to highlight the importance of influenza vaccination as an effective measure in the prevention of cardiorespiratory diseases, especially in the population with underlying chronic diseases.

[Usefulness of the 5MPB-Toledo model to predict bacteremia in patients with community-acquired pneumonia in the Emergency Department]. / Utilidad del modelo 5MPB-Toledo para predecir bacteriemia en el paciente con neumonía adquirida en la comunidad en el Servicio de Urgencias.

OBJECTIVE: To analyse a new risk score to predict bacteremia in the patients with Community-acquired Pneumonia (CAP) in the emergency departments. METHODS: Prospective and multicenter observational cohort study of the blood cultures ordered in 74 Spanish emergency departments for patients with CAP seen from November 1, 2019, to March 31, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC). The prognostic performance for true bacteremia was calculated with the chosen cut-off for getting the sensitivity, specificity, positive predictive value and negative predictive value. RESULTS: A total of 1,020 blood samples wered cultured. True cases of bacteremia were confirmed in 162 (15.9%). The remaining 858 cultures (84.1%) wered negative. And, 59 (5.8%) were judged to be contaminated. The model´s area under the receiver operating characteristic curve was 0.915 (95% CI, 0.898-0.933). The prognostic performance with a model´s cut-off value of ≥ 5 points achieved 97.5% (95% CI, 95.1-99.9) sensitivity, 73.2% (95% CI, 70.2-76.2) specificity, 40.9% (95% CI, 36.4-45.1) positive predictive value and 99.4% (95% CI, 99.1-99.8) negative predictive value. CONCLUSIONS: The 5MPB-Toledo score is useful for predicting bacteremia in the patients with CAP seen in the emergency departments.

Role of IGF2 in the Study of Development and Evolution of Prostate Cancer.

Prostate Cancer (PC) is commonly known as one of the most frequent tumors among males. A significant problem of this tumor is that in early stages most of the cases course as indolent forms, so an active surveillance will anticipate the appearance of aggressive stages. One of the main strategies in medical and biomedical research is to find non-invasive biomarkers for improving monitoring and performing a more precise follow-up of diseases like PC. Here we report the relevant role of IGF2 and miR-93-5p as non-invasive biomarker for PC. This event could improve current medical strategies in PC.

Radiological results of surgical management of fracture of the distal radius treated with volar locking plates.

OBJECTIVES: Distal radius fracture (DRF) is the most common upper extremity fracture. The incidence of complications after surgical treatment still remains high. The objective of our study was to assess functional and radiological results of DRF treated with volar locking plate. METHODS: We conducted a retrospective study including DRF treated by open reduction and internal fixation with a volar locking plate during a period of 8 years (2010-2018). Data were collected from clinical records and included patient demographics, fracture characteristics, radiological parameters (radial inclination, palmar tilt, ulnar variance, articular step-off), range of motion (ROM), complications and reinterventions. RESULTS: A total of 170 patients (63.5% female) met the inclusion criteria with a mean age of 55.9 years [24.1-83.7; 13.76]. High energy injuries were more frequent in younger patients (25.56% vs 3.95%; p < 0.0001). AO classification was: 2R3A: 23.5%, 2R3B: 24.1% and 2R3C: 52.4%. Time until surgery was 8.5 days, longer in extraarticular fractures (AO-2R3A: 12.22 days, AO-2R3B: 7.97 days, AO-2R3C: 7.04 days, p = 0.018). Younger patients had better radial inclination (excellent in 85.1% vs 59.21%, p = 0.001) and radial shortening (excellent in 100% vs 88.15%, p = 0.001). ROM was: flexion 63° [0-90°; 19.73], extension 57.67° [5-90°; 21.61], pronation 78.94° [40-90°] and supination 81.76° [38-90°; 8.87]. We found a weak correlation between ROM in flexion-extension and radial shortening (r = 0.218; p = 0.001) and articular step-off (r = -0.269; p = 0.002). We had 39 complications (21.18% of patients). 10.6% of patients needed a re-operation, being the most frequent hardware removal (6.5%) and tendinous disruptions repairs (2.4%). Reintervention rate was higher in younger patients (14.9% vs 5.3%; p = 0.042), complete articular fractures (AO-2R3A: 2.5%; AO-2R3B: 7.3%; AO-2R3C: 15.7%; p = 0.037) and high energy injuries (8.4% vs 22.2%; p = 0.044). Patients undergoing reintervention had a decreased flexion-extension (94.44° vs 123.83°, p = 0.007). CONCLUSION: Radial shortening and articular step-off seem the most important predictors for postoperative range of motion. Worse radiological outcomes are observed in complete articular fractures and those affecting elder population. Although radiological and functional results are good or excellent in most of cases, the incidence of complications and need for reintervention still remains noticeable. Re-operations were more frequent in younger patients, complete articular fractures and high energy injuries, and it worsened functional outcomes.
