Pretreatment of urine samples with SDS improves direct identification of urinary tract pathogens with matrix-assisted laser desorption ionization-time of flight mass spectrometry
[EN]We pretreated with SDS 71 urine samples with bacterial counts of >10(5) CFU/ml and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) identification scores of <2, in order to minimize failure rates. Identification improved in 46.5% of samples, remained unchanged in 49.3%, and worsened in 4.2%. The improvement was more evident for Gram-negative (54.3%) than for Gram-positive (32%) bacteria
Indicators of Good Practices of Service-Learning University
The proliferation of innovative experiences in university education has been confirmed in different forums, as well as the evidence of their impact in research. However, the available tools are limited when trying to address the quality assessment of University Service-Learning (USL) projects. We present a tool for the evaluation of your SL projects. The goal of the Matrix is to specify the essential and secondary indicators needed to develop good practices in USL: IM_USL.
A protocol is established to carry out its assessment. Dimensions and phases indicators of a project are specied, as well as the agents or people involved in it. This tool tries to guide the development of USL projects and to specify different points to improve. The application of the IM_USL will allow you to explore, exhaustively, each of the dimensions and indicators that make up a USL project, regarding both the AGENTS involved and the PHASES that make up a programme. In order to gather information on the reality of the projects, the phases and agents involved in a USL project will be reviewed in particular, determining the level of achievement of the indicators that compose it and of the dimensions that specify the particularities of each indicator. Finally, a series of questions are proposed to guide the process of analysis and reflection on the quality of the evaluated project. As a result, we will be able to obtain an X-ray of the quality of the project and the possible aspects for improvement.Funding: Spanish Ministry of Science and Innovation.

Intensive care unit discharge to the ward with a tracheostomy cannula as a risk factor for mortality: A prospective, multicenter propensity analysis
To analyze the impact of decannulation before intensive care unit
discharge on ward survival in nonexperimental conditions. DESIGN: Prospective,
observational survey. SETTING: Thirty-one intensive care units throughout Spain.
PATIENTS: All patients admitted from March 1, 2008 to May 31, 2008.
INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: At intensive care unit
discharge, we recorded demographic variables, severity score, and intensive care
unit treatments, with special attention to tracheostomy. After intensive care
unit discharge, we recorded intensive care unit readmission and hospital
survival. STATISTICS: Multivariate analyses for ward mortality, with Cox
proportional hazard ratio adjusted for propensity score for intensive care unit
decannulation. We included 4,132 patients, 1,996 of whom needed mechanical
ventilation. Of these, 260 (13%) were tracheostomized and 59 (23%) died in the
intensive care unit. Of the 201 intensive care unit tracheostomized survivors, 60
were decannulated in the intensive care unit and 141 were discharged to the ward
with cannulae in place. Variables associated with intensive care unit
decannulation (non-neurologic disease [85% vs. 64%], vasoactive drugs [90% vs.
76%], parenteral nutrition [55% vs. 33%], acute renal failure [37% vs. 23%], and
good prognosis at intensive care unit discharge [40% vs. 18%]) were included in a
propensity score model for decannulation. Crude ward mortality was similar in
decannulated and nondecannulated patients (22% vs. 23%); however, after
adjustment for the propensity score and Sabadell Score, the presence of a
tracheostomy cannula was not associated with any survival disadvantage with an
odds ratio of 0.6 [0.3-1.2] (p=.1). CONCLUSION: In our multicenter setting,
intensive care unit discharge before decannulation is not a risk factor
Late gadolinium enhancement distribution patterns in non-ischemic dilated cardiomyopathy: Genotype-phenotype correlation.
AIMS
Late gadolinium enhancement (LGE) is frequently found in patients with dilated cardiomyopathy (DCM), there is little information about its frequency and distribution pattern according to underlying genetic substrate. We sought to describe LGE patterns according to genotype and to analyze the risk of major ventricular arrhythmias (MVA) according to patterns.
METHODS AND RESULTS
Cardiac magnetic resonance findings and LGE distribution according to genetics was performed in a cohort of 600 DCM patients followed at 20 Spanish centers. After exclusion of individuals with multiple causative gene variants or with variants in infrequent DCM-causing genes, 577 patients (34% females, mean age 53.5 years, LVEF 36.9 ± 13.9%) conformed the final cohort. A causative genetic variant was identified in 219 (38%) patients and 147 (25.5%) had LGE. Significant differences were found comparing LGE patterns between genes (P < 0.001). LGE was absent or rare in patients with variants in TNNT2, RBM20 and MYH7 (0%, 5% and 20%, respectively). Patients with variants in DMD, DSP and FLNC showed predominance of LGE subepicardial pattern (50%, 41% and 18%, respectively) whereas patients with variants in TTN, BAG3, LMNA and MYBPC3 showed unspecific LGE patterns. Genetic yield differed according to LGE pattern. Patients with subepicardial, lineal midwall, transmural, right ventricular insertion points or with combination of LGE patterns showed increased risk of MVA compared with patients without LGE.
CONCLUSION
LGE patterns in DCM has a specific distribution according to the affected gene. Certain LGE patterns are associated with increased risk of MVA and with increased yield of genetic testing.This study has been funded by Instituto Salud Carlos III (ISCIII) through the

Natural History of MYH7-Related Dilated Cardiomyopathy
BACKGROUND Variants in myosin heavy chain 7 (MYH7) are responsible for disease in 1% to 5% of patients with dilated cardiomyopathy (DCM); however, the clinical characteristics and natural history of MYH7-related DCM are poorly described. OBJECTIVES We sought to determine the phenotype and prognosis of MYH7-related DCM. We also evaluated the influence of variant location on phenotypic expression. METHODS We studied clinical data from 147 individuals with DCM-causing MYH7 variants (47.6% female; 35.6 +/- 19.2 years) recruited from 29 international centers. RESULTS At initial evaluation, 106 (72.1%) patients had DCM (left ventricular ejection fraction: 34.5% +/- 11.7%). Median follow-up was 4.5 years (IQR: 1.7-8.0 years), and 23.7% of carriers who were initially phenotype-negative developed DCM. Phenotypic expression by 40 and 60 years was 46% and 88%, respectively, with 18 patients (16%) first diagnosed at <18 years of age. Thirty-six percent of patients with DCM met imaging criteria for LV noncompaction. During follow-up, 28% showed left ventricular reverse remodeling. Incidence of adverse cardiac events among patients with DCM at 5 years was 11.6%, with 5 (4.6%) deaths caused by end-stage heart failure (ESHF) and 5 patients (4.6%) requiring heart transplantation. The major ventricular arrhythmia rate was low (1.0% and 2.1% at 5 years in patients with DCM and in those with LVEF of <= 35%, respectively). ESHF and major ventricular arrhythmia were significantly lower compared with LMNA-related DCM and similar to DCM caused by TTN truncating variants. CONCLUSIONS MYH7-related DCM is characterized by early age of onset, high phenotypic expression, low left ventricular reverse remodeling, and frequent progression to ESHF. Heart failure complications predominate over ventricular arrhythmias, which are rare. (C) 2022 The Authors. Published by Elsevier on behalf of the American College of Cardiology Foundation

TRY plant trait database – enhanced coverage and open access
Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20
[1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030
Ferroelectric and Piezoelectric Characterization of Porous (K, Na, Li)(Nb, Ta, Sb)O<sub>3</sub>
Polvo de KNL-NTS con estequiometria (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3 fue preparado siguiendo el método convencional cerámico de mezcla de carbonatos y óxidos. La síntesis del polvo de KNL-NTS fue llevada a cabo en estado sólido a 700 ºC durante 3h. Para obtener muestras cerámicas con diferente porosidad, se llevó a cabo la sinterización de pastillas en un rango de temperaturas entre 1088 y 1125 ºC durante 2h en aire. Las muestras fueron caracterizadas estructural y microestructuralmente mediante DRX y MEB, y se determinó el grado y tipo de porosidad mediante porosimetría de intrusión de mercurio. Se investigó la influencia de la temperatura de sinterización en la porosidad y se evaluó el impacto de la misma en los ciclos de histéresis ferroeléctricos y la respuesta piezoeléctrica de las pastillas. La máxima densificación del material se consigue a 1125 ºC y la mejor respuesta ferroeléctrica, en pastillas sinterizadas a 1112 ºC. Por su parte, se observó que pastillas fabricadas en un rango de temperaturas inferior (1094-1100 ºC) donde la porosidad alcanza valores de hasta 15 % presentan buena respuesta piezo-ferroeléctrica, similar a la encontrada en las pastillas sinterizadas a 1125 ºC.KNL-NTS powder with (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3 stoichiometry was prepared following the conventional ceramic method of mixing carbonates and oxides. KNL-NTS powder synthesis is carried out in solid state at 700°C for 3h. To obtain ceramic samples with different porosity the sintering of pellets is carried out in air at different temperatures between 1088 and 1125°C for 2h. Structural and microstructural characterizations are performed by XRD and SEM and the degree and type of porosity is determined by mercury intrusion porosimetry. The influence of sintering temperature on the porosity and its consequence on both the ferroelectric hysteresis loops and the piezoelectric response was evaluated. The maximum densification is achieved at 1125°C and the best ferroelectric response is achieved in sintered pellets at 1125°C. Meanwhile, it was observed that pellets sintered in a lower temperature range (1094-1100°C) where porosity reaches values up to 15 % have good ferroelectric piezoelectric response, similar to that found in the sintered pellets to 1125°C.Facultad de Ciencias Exacta
