La responsabilidad internacional del fabricante por productos. A propósito del asunto Honeywell y ACSS

El presente trabajo se centra en el accidente aéreo acaecido la noche del 1 de julio de 2002, fecha en la que tuvo lugar una colisión en espacio aéreo alemán (Überlingen) entre un avión Tupolev modelo TU-154M de la compañía aérea rusa Bashkirian Airlines, cuyo destino era Barcelona (España) y un avión Boeing, explotado por la compañía DHL Airways. Ambas aeronaves estaban provistas del sistema anticolisión TCAS. Los familiares rusos de las víctimas que viajaban en el avión Tupolev interpusieron demanda contra los fabricantes norteamericanos del referido sistema de anticolisión (Aviation Communications and Surveillance Systems y Honeywell Internacional INC), por cuanto consideraron que el producto era defectuoso y había sido causa directa del accidente aéreo. El presente estudio tiene por objeto analizar el asunto expuesto desde una perspectiva de Derecho internacional privado. De este modo, se dará respuesta a dos de los sectores que constituyen el objeto de esta rama del Derecho, la competencia judicial internacional y el Derecho aplicable a la relación jurídica internacional existente entre los familiares de los finados y los fabricantes del sistema anticolisión TCAS

Measuring depression in Primary Health Care in Spain : Psychometric properties and diagnostic accuracy of HSCL-5 and HSCL-10

Depression has a high prevalence among European countries. Several instruments have been designed to assess its symptoms in different populations. The Hopkins Symptom Checklist 25 (HSCL-25) scale has been identified as valid, reproducible, effective, and easy to use. There are short versions of this scale that could be useful in Primary Care (PC) settings, but their psychometric properties are unknown. To assess in PC patients the psychometric properties and diagnostic accuracy of the Spanish version of the HSCL-10 and the HSCL-5 consisting of 10 and 5 items, respectively. A multicenter, cross-sectional study was carried out at six PC centers in Spain. The HSCL-25 was administered to outpatients aged 45-75 who also participated in the structured Composite International Diagnostic Interview (CIDI). HSCL-10 and HSCL-5 were assessed and compared to HSCL-25 regarding total score correlation, internal consistency, and criterion validity against the gold-standard CIDI. This is a methodological study from a secondary data analysis and the primary data has been previously published. Out of 790 patients, 767 completed the HSCL-25 and 736 the CIDI interview (96.0%). Cronbach's Alpha was 0.84 for HSCL-10 and 0.77 for HSCL-5. The known-group method and confirmatory factor analysis were acceptable for the establishment of construct validity. Sensitivity was 79.7% (CI95%, 67.7-88.0%) for HSCL-10, and 78.0% (CI95%, 65.9-86.6%) for HSCL-5, whereas specificity was 83% (CI95%, 80.0-85.7%) for HSCL-10, and 72.8% (CI95%, 69.3-76.0%) for HSCL-5. Area under the curve against CIDI was 0.88 (CI95%, 0.84-0.92%) for HSCL-10, and 0.85 (CI95%, 0.81-0.89%) for HSCL-5. Optimum cutoff point calculated with Youden Index was 1.90 for the HSCL-10 and 1.80 for the HSCL-5. HSCL-10 and HSCL-5 are reliable and valid tools to detect depression symptoms and can be used in PC settings

Structural insights into the intracellular region of the human magnesium transport mediator CNNM4

The four member family of “Cyclin and Cystathionine β-synthase (CBS) domain divalent metal cation transport mediators”, CNNMs, are the least-studied mammalian magnesium transport mediators. CNNM4 is abundant in the brain and the intestinal tract, and its abnormal activity causes Jalili Syndrome. Recent findings show that suppression of CNNM4 in mice promotes malignant progression of intestinal polyps and is linked to infertility. The association of CNNM4 with phosphatases of the regenerating liver, PRLs, abrogates its Mg2+-efflux capacity, thus resulting in an increased intracellular Mg2+ concentration that favors tumor growth. Here we present the crystal structures of the two independent intracellular domains of human CNNM4, i.e., the Bateman module and the cyclic nucleotide binding-like domain (cNMP). We also derive a model structure for the full intracellular region in the absence and presence of MgATP and the oncogenic interacting partner, PRL-1. We find that only the Bateman module interacts with ATP and Mg2+, at non-overlapping sites facilitating their positive cooperativity. Furthermore, both domains dimerize autonomously, where the cNMP domain dimer forms a rigid cleft to restrict the Mg2+ induced sliding of the inserting CBS1 motives of the Bateman module, from a twisted to a flat disk shaped dimer.Gobierno Vasco PI2010-17, IE05-147, IE07-202Diputación Foral de Vizcaya 7/13/08/2006/11, 7/13/08/2005/14Ministerio de Ciencia e Innovación BFU2010-17857, CSD2008-00005Ministerio de Economía y Competitividad BFU2013-47531-R, BES-2014-068464, BFU2016-77408-R, BES-2017-08043

Impact of Previous Physical Activity Levels on Symptomatology, Functionality, and Strength during an Acute Exacerbation in COPD Patients

The main objective of this study is to determine the relationship between physical activity (PA) level prior to hospitalization and the pulmonary symptomatology, functionality, exercise capacity, and strength of acute exacerbated chronic obstructive pulmonary disease (COPD) patients. In this observational study, all data were taken during the patient’s first day in hospital. Patients were divided into two groups (a PA group, and a physical inactivity (PI) group), according to the PA level evaluated by the Baecke questionnaire. Cough status was evaluated by the Leicester Cough Questionnaire (LCQ), and dyspnea was assessed using the modified Medical Research Council dyspnea scale (mMRC). Functionality was measured by the Functional Independence Measure (FIM) and the London Chest Activity of Daily Living scale (LCADL). Exercise capacity was evaluated by the two-minute step-in-place (2MSP) test, and strength assessed by dynamometry. A total of 151 patients were included in this observational study. Patients in the PI group obtained worse results compared to the PA group, and significant differences (p < 0.05) were found in all of the variables. Those COPD patients who regularly perform PA have less dyspnea and cough, as well as better functionality, exercise capacity and strength during an exacerbation, without relationship to the severity of the pathology.The author JRT has received financial support through a FPU (“Formación Profesorado Universitario”) grant (FPU:16/01531) of the Spanish Ministry of Education.

Hypoxia matters: comparison of external and internal training load markers during an 8‑week resistance training program in normoxia, normobaric hypoxia and hypobaric hypoxia

Purpose To compare external and internal training load markers during resistance training (RT) in normoxia (N), intermittent hypobaric hypoxia (HH), and intermittent normobaric hypoxia (NH). Methods Thirty-three volunteers were assigned an 8-week RT program in either N (690 m, n = 10), HH (2320 m, n = 10), or NH (inspired fraction of oxygen = 15.9%; ~ 2320 m, n = 13). The RT program (3x/week) consisted of six exercises, with three sets of six to 12 repetitions at ~ 70% of one repetition maximum (1RM) with the first session of each week sed for analysis. 1RM in back squat and bench press was used to evaluate muscle strength before and after the program. External load was assessed by the volume load relative to body mass (RVL, kg·kg−1). Internal load was assessed by the ratings of perceived exertion (RPE) and heart rate (HR). Results Smaller relative improvements were found for the back squat in the N group (11.5 ± 8.8%) when compared to the NH group (22.2 ± 8.2%, P = 0.01) and the HH group (22 ± 8.1%, P = 0.02). All groups showed similar RVL, HR responses and RPE across the program (P˃0.05). However, reduced HR recovery values, calculated as the difference between the highest HR value (HRpeak) and the resting heart rate after a two min rest, were seen in the N and NH groups across the program (P < 0.05). Conclusion It seems that 8 weeks of intermittent RT in hypoxic environments could maximize time-efficiency when aiming to improve strength levels in back squat without evoking higher levels of physiological stress. Performing RT at hypobaric hypoxia may improve the cardiorespiratory response, which in turn could speed recovery.Open access funding provided by Örebro UniversitySpanish Ministry of Science, Innovation and Universities under grant [PGC2018-097388-B-I00-MCI/AEI/FEDER, UE]Andalusian FEDER Operational Program [B-CTS-374-UGR20]FPU pre-doctoral grant [FPU18/00686

Utility of Transient Elastography for the Screening of Liver Disease in Patients with Alpha1-Antitrypsin Deficiency

Deficiència d'alfa1-antitripsina; Malaltia del fetge; Elastografia transitòriaAlpha1-antitrypsin deficiency; Liver disease; Transient elastographyDeficiencia de alfa1-antitripsina; Enfermedad del hígado; Elastografía transitoriaScreening of liver disease in alpha-1 antitrypsin deficiency (AATD) is usually carried out with liver enzymes, with low sensitivity. We conducted a multicenter cross-sectional study aiming to describe the utility of transient elastography for the identification of liver disease in patients with AATD. A total of 148 AATD patients were included. Among these, 54.7% were Pi*ZZ and 45.3% were heterozygous for the Z allele. Between 4.9% and 16.5% of patients had abnormal liver enzymes, without differences among genotypes. Liver stiffness measurement (LSM) was significantly higher in Pi*ZZ individuals than in heterozygous Z (5.6 vs. 4.6 kPa; p = 0.001). In total, in 8 (5%) individuals LSM was >7.5 kPa, considered significant liver fibrosis, and ≥10 kPa in 3 (1.9%) all being Pi*ZZ. Elevated liver enzymes were more frequently observed in patients with LSM > 7.5 kPa, but in 5 out of 8 of these patients all liver enzymes were within normal range. In patients with AATD, the presence of abnormal liver enzymes is frequent; however, most of these patients do not present significant liver fibrosis. Transient elastography can help to identify patients with liver fibrosis even with normal liver enzymes and should be performed in all Z-allele carriers to screen for liver disease.This research was funded by Grifols through an unrestricted grant from the Catalan Center for Research in Alpha-1 antitrypsin deficiency of the Vall d’Hebron Research Institute (VHIR) in the Vall d’Hebron Barcelona Hospital Campus, Barcelona, Spain; from the Madrid Center for Research in Alpha-1 antitrypsin deficiency of the Hospital Clínico San Carlos, Madrid, Spain; from the Galicia Center for Research in Alpha-1 antitrypsin deficiency of the University Hospital Complex of Vigo, Spain; as well as a research grant from Fundació Catalana de Pneumologia (FUCAP)

In vitro activity of essential oils against microbial isolates from otitis externa cases in dogs

[EN] Despite the number of studies focused on the potential use of essential oils (EOs) as an alternative to conventional treatments of canine external otitis, there is controversy about their antimicrobial activity which could be explained by differences in technical or biological aspects. This study focuses on the antimicrobial activity of three single EO compounds (thymol, cinnamaldehyde and carvacrol) and two EOs (clove and oregano) against clinical isolates recovered from canine otitis externa cases (14 bacterial isolates belonging to five different genera and six Malassezia pachydermatis isolates). All compounds showed activity and cinnamaldehyde exhibited the highest bactericidal and fungicidal activity. The susceptibility was lower among bacterial isolates than fungal isolates, being this difference more evident for Gram-positive bacteria. No relationship between antibiotic multi-resistant profile and susceptibility to compounds was observed. To sum up, our results provide appropriate information about appropriate concentrations of promising candidates for the topic treatment of canine otitis.SIManuel Gómez-García was supported by grant from Junta de Castilla y León co-financed by the European Social Fund (LE131-18).

Spirometry and respiratory oscillometry: Feasibility and concordance in schoolchildren with asthma

Producción CientíficaObjective:The purpose of this study was to describe the feasibility of respiratory oscillometry (RO) in schoolchildren with asthma, and the concordance of its results with those of spirometry, to determine its clinical usefulness. Methods:RO and spirometry were performed in 154 children (6 to 14-year-old) with asthma, following strict quality criteria for the tests. Their feasibility (probability of valid test, time of execution, number of maneuvers needed to achieve a valid test, and perceived difficulty) was compared. The factors that influence feasibility were analyzed with multivariate methods. FEV1, FEV1/FVC, FVC and FEF25-75 for spirometry, and R5, AX and R5-19 for RO, were converted into z-scores and their concordance was investigated through intraclass correlation coefficients (ICC) and kappa indices for normal/abnormal values. Results:There were no differences in the probability of obtaining a valid RO or spirometry (83.1% vs. 81.8%, p = 0.868). RO required a lower number of maneuvers [mean (SD) 4.2 (1.8) versus 6.0 (1.6), p < 0.001] and less execution time [5.1 (2.7) versus 7.6 (2.4) minutes, p < 0.001], and patients considered it less difficult. Age increased the probability of obtaining valid RO and spirometry. The concordance of results between RO and spirometry was low, and only between zFEV1 and zAX could it be considered moderate (ICC = 0.412, kappa = 0.427). Conclusion:RO and spirometry are feasible in children with asthma. RO has some practical advantages, but the concordance of its results with spirometry is low.Junta de Castilla y León (Gerencia Regional de Salud - Grant/Award Number: 2191/A/2020

Antenatal Fear of Childbirth as a Risk Factor for a Bad Childbirth Experience

Giving birth is one of the most impressive experiences in life. However, many pregnant women suffer from fear of childbirth (FOC) and experience labour in very different ways, depending on their personality, previous life experiences, pregnancy, and birth circumstances. The aim of this study was to analyse how fear of childbirth affects the childbirth experience and to assess the related consequences. For this, a descriptive cross-sectional study was carried out in a sample of 414 women between 1 July 2021 and 30 June 2022. The Birth Anticipation Scale (BAS) was used to measure fear of childbirth and the Childbirth Experience Questionnaire (CEQ-E) was applied to measure satisfaction with the childbirth experience. Fear of childbirth negatively and significantly predicted the childbirth experience. In addition, women who were more fearful of childbirth were found to have worse obstetric outcomes and a higher likelihood of having a caesarean delivery (p = 0.008 C. I 95%). Fear behaved as a risk factor for the birth experience, so the greater the fear, the higher the risk of having a worse birth experience (OR 1.1). Encouraging active listening and support strategies may increase pregnant women's confidence, thus decreasing their fear of the process and improving their childbirth experience
