Molecular epidemiology of circulating clinical isolates is crucial to improve prevention strategies. The Spanish Working Group on multidrug resistant tuberculosis (MDR-TB) is a network that monitors the MDR-TB isolates in Spain since 1998. The aim of this study was to present the study of the MDR-TB and extensively drug-resistant tuberculosis (XDR-TB) patterns in Spain using the different recommended genotyping methods over time by a national coordinated system. Based on the proposed genotyping methods in the European Union until 2018, the preservation of one method, MIRU-VNTR, applied to selected clustered strains permitted to maintain our study open for 20 years. The distribution of demographic, clinical and epidemiological characteristics of clustered and non-clustered cases of MDR/XDR tuberculosis with proportion differences as assessed by Pearson's chi-squared or Fisher's exact test was compared. The differences in the quantitative variables using the Student's-t test and the Mann-Whitney U test were evaluated. The results obtained showed a total of 48.4% of the cases grouped in 77 clusters. Younger age groups, having a known TB case contact (10.2% vs 4.7%) and XDR-TB (16.5% vs 1.8%) were significantly associated with clustering. The largest cluster corresponded to a Mycobacterium bovis strain mainly spread during the nineties. A total of 68.4% of the clusters detected were distributed among the different Spanish regions and six clusters involving 104 cases were grouped in 17 and 18 years. Comparison of the genotypes obtained with those European genotypes included in The European Surveillance System (TESSy) showed that 87 cases had become part of 20 European clusters. The continuity of MDR strain genotyping in time has offered a widespread picture of the situation that allows better management of this public health problem. It also shows the advantage of maintaining one genotyping method over time, which allowed the comparison between ancient, present and future samples. The molecular methods applied in this work were supported by the Carlos III Health Institute in the context of two consecutive Grants FIS15/0317 and 18/0336 and JC was awarded a scholarship by the Government of Aragon / European Social Fund, “Building Europe from Aragon”.

AIMS: The role of revascularization in chronic coronary syndrome (CCS) and the value of ischaemia vs. anatomy to guide decision-making are in constant debate. We explored the potential of a combined assessment of ischaemic burden by vasodilator stress cardiovascular magnetic resonance (CMR) and presence of multivessel disease by angiography to predict the effect of revascularization on all-cause mortality in CCS. METHODS AND RESULTS: The study group comprised 1066 CCS patients submitted to vasodilator stress CMR pre-cardiac catheterization (mean age 66 ± 11 years, 69% male). Stress CMR-derived ischaemic burden (extensive if >5 ischaemic segments) and presence of multivessel disease in angiography (two- or three-vessel or left main stem disease) were computed. The influence of revascularization on all-cause mortality was explored and adjusted hazard ratios (HRs) with the corresponding 95% confidence intervals were obtained. During a median 7.51-year follow-up, 557 (52%) CMR-related revascularizations and 308 (29%) deaths were documented. Revascularization exerted a neutral effect on all-cause mortality in the whole study group [HR 0.94 (0.74-1.19), P = 0.6], in patients without multivessel disease [n = 598, 56%, HR 1.12 (0.77-1.62), P = 0.6], and in those with multivessel disease without extensive ischaemic burden [n = 181, 17%, HR 1.66 (0.91-3.04), P = 0.1]. However, compared to non-revascularized patients, revascularization significantly reduced all-cause mortality in patients with simultaneous multivessel disease and extensive ischaemic burden (n = 287, 27%): 3.77 vs. 7.37 deaths per 100 person-years, HR 0.60 (0.40-0.90), P = 0.01. CONCLUSIONS: In patients with CCS submitted to catheterization, evidence of simultaneous extensive CMR-related ischaemic burden and multivessel disease identifies the subset in whom revascularization can reduce all-cause mortality.

BACKGROUND: Stress cardiac MRI permits comprehensive evaluation of patients with known or suspected chronic coronary syndromes (CCS). The impact of sex on the use of invasive cardiac angiography (ICA) after vasodilator stress cardiac MRI is unclear.; PURPOSE: To evaluate the impact of sex on ICA use after vasodilator stress cardiac MRI.; STUDY TYPE: Retrospective.; POPULATION: A total of 6229 consecutive patients (age [mean±standard deviation] 65.2±11.5years, 38.1% women).; FIELD STRENGTH/SEQUENCE: A 5-T; a steady-state free-precession cine sequence; stress first-pass perfusion imaging; late enhancement imaging.; ASSESSMENT: Patients underwent vasodilator stress cardiac MRI for known or suspected CCS. The ischemic burden (at stress first-pass perfusion imaging) was computed (17-segment model).; STATISTICAL TESTS: Multivariate logistic regression was used to evaluate the potential differential association between ischemic burden and use of cardiac MRI-related ICA across sex.; RESULTS: A total of 1109 (17.8%) patients were referred to ICA, among which there were significantly more men (762, 19.7%) than women (347, 14.6%). Overall, after multivariate adjustment, female sex was not associated with lower use of ICA (odds ratio [OR]=0.99; confidence interval [CI] 95%: 0.84-1.18, P=0.934). However, significant sex differences were detected across ischemic burden. Whereas women with nonischemic vasodilator stress cardiac MRI (0 ischemic segments) were less commonly submitted to ICA (OR=0.49; CI 95%: 0.35-0.69) in patients with ischemia (>1 ischemic segment), adjusted use of ICA was more frequent in women than men (OR=1.27; CI 95%: 1.1-1.5).; DATA CONCLUSIONS: In patients with known or suspected CCS submitted to undergo vasodilator stress cardiac MRI, cardiac MRI-related ICA may be overused in men without ischemia. Furthermore, ICA referral in patients with negative ischemia resulted in greater odds of revascularization in men.; EVIDENCE LEVEL: 3 TECHNICAL EFFICACY: Stage 5. © 2022 International Society for Magnetic Resonance in Medicine.

The present article discusses the New Education Movement pedagogical ideas influence in Chile during the dictatorship of Carlos Ibañez del Campo (1927-1931), a period which saw the opening of several experimental schools (1929-1931). Over a dozen photographs, alongside journalistic and internal records from the archive at the Experimental School for Girls in Santiago are examined. Three dimensions of schooling are brought to focus: 1) Outline of the learning environment; 2) Student involvement; 3) Approaches to learning., CABÁS, Выпуск 27 (1-27) 2022, Pages 137-158

Objectives: To evaluate the potential epidemiologic and economic impact of applying an HIV screening protocol in hospital emergency departments (ED) and compare it to current clinical practice in Spain. Material and methods: We estimated the cumulative incidence of human immunodeficiency virus (HIV) infections and associated costs in Spain for a 20-year time horizon based on a model comprised of various health states with different risks for HIV transmission. The impact of current clinical practices in Spain, in which there is no established protocol for HIV screening, was compared to the potential impact of applying a targeted screening protocol in persons who come to the ED with certain conditions suggestive of HIV infection (diagnosis of a sexually transmitted infection, mononucleosis, herpes zoster infection, community-acquired pneumonia; practice of chemsex, and need for postexposure prophylaxis). Results: Screening all persons with a condition suggestive of HIV infection in hospital EDs would require an investment of epsilon 20 million over 20 years, but it would prevent 13 615 new infections (reducing the incidence by 20.6%, down from 66 265 to 52 650 cases) in comparison with the current diagnostic approaches. Such a reduction in the incidence of HIV infection would potentially save epsilon 4411 million over 20 years, giving a return of epsilon 224 per euro invested. Conclusion: A protocol for targeted screening of persons in circumstances suggestive of risk for HIV infection in Spain would increase diagnoses, avert new infections, and generate savings in comparison with screening practices currently in effect.

Collagen bundle orientation (CBO) in myocardial infarct scars plays a major role in scar mechanics and complications after infarction. We aim to compare four histopathological methods for CBO measurement in myocardial scarring. Myocardial infarction was induced in 21 pigs by balloon coronary occlusion. Scar samples were obtained at 4 weeks, stained with Masson's trichrome, Picrosirius red, and Hematoxylin-Eosin (H&E), and photographed using light, polarized light microscopy, and confocal microscopy, respectively. Masson's trichrome images were also optimized to remove non-collagenous structures. Two observers measured CBO by means of a semi-automated, Fourier analysis protocol. Interrater reliability and comparability between techniques were studied by the intraclass correlation coefficient (ICC) and Bland-Altman (B&A) plots and limits of agreement. Fourier analysis showed an almost perfect interrater reliability for each technique (ICC >= 0.95, p < 0.001 in all cases). CBO showed more randomly oriented values in Masson's trichrome and worse comparability with other techniques (ICC vs. Picrosirius red: 0.79 [0.47-0.91], p = 0.001; vs. H&E-confocal: 0.70 [0.26-0.88], p = 0.005). However, optimized Masson's trichrome showed almost perfect agreement with Picrosirius red (ICC 0.84 [0.6-0.94], p < 0.001) and H&E-confocal (ICC 0.81 [0.54-0.92], p < 0.001), as well as these latter techniques between each other (ICC 0.84 [0.60-0.93], p < 0.001). In summary, a semi-automated, Fourier-based method can provide highly reproducible CBO measurements in four different histopathological techniques. Masson's trichrome tends to provide more randomly oriented CBO index values, probably due to non-specific visualization of non-collagenous structures. However, optimization of Masson's trichrome microphotographs to remove non-collagenous components provides an almost perfect comparability between this technique, Picrosirius red and H&E-confocal.

INTRODUCTION AND OBJECTIVES: The management of elderly patients with chronic coronary syndrome (CCS) is challenging. We explored the prognostic value and usefulness for decision-making of ischemic burden determined by vasodilator stress cardiac magnetic resonance (CMR) imaging in elderly patients with known or suspected CCS. METHODS: The study group comprised 2496 patients older than 70 years who underwent vasodilator stress CMR for known or suspected CCS. The ischemic burden (number of segments with stress-induced perfusion deficit) was calculated following the 17-segment model. Subsequently, we retrospectively analyzed its association with all-cause mortality and the effect of CMR-guided revascularization. RESULTS: During a median follow-up of 4.58 years, there were 430 deaths (17.2%). A higher ischemic burden was an independent predictor of mortality (HR, 1.04; 95%CI, 1.01-1.07 for each additional ischemic segment; P=.006). This association was also found in patients older than 80 years and in women (P
