Um estudo descritivo dos resultados obstétricos e neonatais em dois modelos de assistência ao parto em primíparas

Introduction: In the 20th century, childbirth went from being attended at home to the hospital setting. Inappropriate and unnecessary interventions were uncritically adopted, leading to a dehumanization of childbirth. This is the model that currently exists in most Spanish hospitals, which has been questioned by the World Health Organization as early as 1996. Objective: The aim is to describe the differences in obstetrical and neonatal results across two different models of maternity care (biomedical model and humanised birth). Method: A correlational descriptive and multicenter study was carried out. A convenience sample of 205 primiparous women, 110 biomedical model and 95 humanised model, were recruited. Obstetrical and neonatal results were compared in two hospitals with different models of maternity care in Spain. Results: The humanised model of maternity care produces better obstetrical outcomes (spontaneous beginning of labour, normal vaginal birth, intact perineum and I degree tear and less episiotomies) than the biomedical model. There were no differences in neonatal outcomes. Conclusion: The benefits of implementing a humanised model of delivery care should be considered by health policy makers and reflected in the woman and her baby.Introducción: En el siglo XX el parto pasó de ser atendido en casa al ámbito hospitalario. Se adoptaron de forma acrítica intervenciones inapropiadas e innecesarias que condujeron a una deshumanización del parto. Este es el modelo que existe actualmente en la mayoría de los hospitales españoles y que fue cuestionado por la OMS ya en 1996. Objetivo: Describir las diferencias que existen en los resultados obstétricos y neonatales en primíparas en dos modelos distintos de asistencia al parto (biomédico y humanizado). Método: Se llevó a cabo un estudio descriptivo, de corte transversal. Se obtuvo una muestra por conveniencia de 205 primíparas, 110 del modelo biomédico y 95 del humanizado. Se compararon los resultados obstétricos y neonatales en dos hospitales con modelos diferentes de asistencia al parto en España. Resultados: En el modelo humanizado de asistencia al parto se obtuvieron unos mejores resultados obstétricos (inicio espontáneo, parto eutócico, periné íntegro o desgarro de I grado y menos episiotomías) que en el biomédico. No hubo diferencias en los resultados neonatales. Conclusión: Los beneficios de instaurar un modelo humanizado de asistencia al parto deberían ser considerados por los responsables de políticas sanitarias y reflejados en la mujer y su criatura.Introdução: No século XX, o parto deixou de ser realizado em casa para ser realizado no ambiente hospitalar.

Não houve diferença nos resultados neonatais. Conclusão: Os benefícios da implementação de um modelo humanizado de assistência ao parto devem ser considerados pelos formuladores de políticas de saúde e refletidos na mulher e em seu bebê

The Application of a System of Eye Tracking in Laparoscopic Surgery: A New Didactic Tool to Visual Instructions

Introduction: Laparoscopic surgery is an increasingly used technique, but it requires a high degree of learning, and communication between the operating room crew is considerably difficult. The use of eye tracking has been proposed as a didactic and evaluation tool in several settings, including in laparoscopy in simulators.Objectives: This study aimed to evaluate the usefulness of the use of eye tracking systems (Tobii glasses 2) in laparoscopic surgery as a didactic and assessment tool to improve communication in the operating room and improve patients' security.Methodology: An anonymous survey was sent to the students and medical teachers of a faculty of medicine and practicing doctors and residents. The message contained an explanation about the use of the Tobii glasses, a link to watch the video showing its use in a laparoscopic surgery, and the survey to complete after watching the video.Results: The survey was answered by 113 participants (51.3% medical students, 27.4% medical teachers, 18.6% practicing doctors, and 2.7% medicine residents). Eighty-three percent agreed with the usefulness of the “Tobii glasses” in the operating room for improving communication between the main surgeon and the assistant, for learning complex surgery techniques, for obtaining didactic videos, and for indicating anatomical structures. The item scored worst was the price of the glasses.Conclusions: It is possible to record and project expert gaze patterns in the operating room in real time using the Tobii glasses. This device allows improving communication among the surgical crew and the learning of residents and also improving the security of surgical patients

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Evaluación del riesgo del puesto de trabajo de un operario de taller de vehículos a motor y medidas de adaptación ante el diagnóstico reciente de epilepsia

Introducción La prevención de riesgos laborales es una acción necesaria que se ha de realizar en todos los trabajadores y que el empresario debe garantizar. Debe ser cuidadosamente realizada en personas con un elevado riesgo como los trabajadores especialmente sensibles a determinados riesgos, entre los que se incluyen los trabajadores diagnosticados de epilepsia. Sin embargo, esta enfermedad conlleva importantes despidos y marginamiento en el ámbito laboral. El objetivo de este trabajo es revisar la normativa vigente y las limitaciones que la enfermedad conlleva para poder realizar de forma apropiada una valoración del riesgo de su puesto de trabajo y aplicarla de forma práctica a un caso hipotético en el que a un mecánico de vehículos a motor se le diagnostica de epilepsia. Resultados: Para poder realizar de forma apropiada la valoración del riesgo del trabajador, hay que conocer el tipo de crisis de cada trabajador, la etiología de su epilepsia si es posible y su control con el tratamiento. Además, habrá que realizar una apropiada valoración del riesgo del puesto de trabajo y contrastar si las actividades a realizar están permitidas, dado que algunas tareas implican riesgo para sí mismos y para terceros. Conclusiones El diagnóstico de epilepsia no debe ir acompañado de discriminación y limitaciones para realizar la actividad laboral, sino que debe iniciarse un proceso combinado por parte de los organismos públicos, Servicios de Prevención y servicios sanitarios para conseguir una buena valoración del riesgo del puesto de trabajo y la correspondiente adaptación del mismo

A “Episiotomia” se identificou erroneamente como protetor do períneo por ginecologistas e MIR (p = 0.003). Conclusão: O grau de conhecimento e uso dos métodos de proteção do períneo dos profissionais não se corresponde com as recomendações da Organização Mundial da Saúde.Objective: To analyse the knowledge and use of perineal protection methods during the expulsive stage by health professionals involved in childbirth and whether they correspond to the World Health Organization’s recommendations. Method: This was a cross-sectional descriptive study aimed at health workers involved in births in Spain. Results: Fifty-seven professionals participated in the study: midwives (47%), gynaecologists (25%), nurse residents (14%) and resident physicians (14%) in obstetrics and gynaecology. The degree of knowledge and use of perineal protection methods differed according to the position held and was very limited among gynaecologists and resident physicians. The only method recognized by all positions was “hands on” (p = 0.05). “Hands off ” (p = 0.002), “delayed pushing” (p = 0.0001) and “maternal posture” (p = 0.03) were only known to midwives and nurse residents. “Flexion technique” (p = 0.035) and “delayed pushing” (p = 0.011) were used effectively by midwives and nurse residents. “Episiotomy” was erroneously identified as a method to protect the perineum by gynaecologists and resident physicians (p = 0.003). Conclusion: The degree of knowledge and use of perineal protection methods by health care professionals does not correspond to the recommendations of the World Health Organization

Heavy flavour decay muon production at forward rapidity in proton–proton collisions at √s=7 TeV

The production of muons from heavy flavour decays is measured at forward rapidity in proton–proton collisions at √s=7 TeV collected with the ALICE experiment at the LHC. The analysis is carried out on a data sample corresponding to an integrated luminosity Lint=16.5 nb−1. The transverse momentum and rapidity differential production cross sections of muons from heavy flavour decays are measured in the rapidity range 2.5<y<4, over the transverse momentum range 2<pt<12 GeV/c. The results are compared to predictions based on perturbative QCD calculations

Measurement of electrons from semileptonic heavy-flavour hadron decays at midrapidity in pp and Pb–Pb collisions at √sNN = 5.02 TeV

The differential invariant yield as a function of transverse momentum (pT) of electrons from semileptonic heavy-flavour hadron decays was measured at midrapidity in central (0–10%), semi-central (30–50%) and peripheral (60–80%) lead–lead (Pb–Pb) collisions at √sNN = 5.02 TeV in the pT intervals 0.5–26 GeV/c (0–10% and 30–50%) and 0.5–10 GeV/c (60–80%). The production cross section in proton–proton (pp) collisions at √s = 5.02 TeV was measured as well in 0.5 < pT < 10 GeV/c and it lies close to the upper band of perturbative QCD calculation uncertainties up to pT = 5 GeV/c and close to the mean value for larger pT. The modification of the electron yield with respect to what is expected for an incoherent superposition of nucleon–nucleon collisions is evaluated by measuring the nuclear modification factor RAA. The measurement of the RAA in different centrality classes allows in-medium energy loss of charm and beauty quarks to be investigated. The RAA shows a suppression with respect to unity at intermediate pT, which increases while moving towards more central collisions. Moreover, the measured RAA is sensitive to the modification of the parton distribution functions (PDF) in nuclei, like nuclear shadowing, which causes a suppression of the heavy-quark production at low pT in heavy-ion collisions at LHC

Coherent J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at √sNN=2.76 TeV

The ALICE Collaboration has made the first measurement at the LHC of J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at sNN=2.76 TeV. The J/ψ is identified via its dimuon decay in the forward rapidity region with the muon spectrometer for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 55 μb−1. The cross section for coherent J/ψ production in the rapidity interval −3.6<y<−2.6 is measured to be dσJ/ψcoh/dy=1.00±0.18(stat)−0.26+0.24(syst) mb. The result is compared to theoretical models for coherent J/ψ production and found to be in good agreement with those models which include nuclear gluon shadowing
