OBJECTIVE: To determine the complications related to complementary anticoagulation therapy and the probability of risk. METHODS: One-hundred and sixty-three patients who underwent heart valve replacement between 2002 and 2016 with either mechanical or biological prostheses, and who received vitamin K antagonists after hospital discharge, were studied...

In this paper I am arguing for the recognition of the implicit structural and emotional links between the development of mind and psyche and the more-than-human world. I suggest that it is because of this interpenetration that the uncanny experience of displacement anxiety and its effects on our capacities to think and make links is an under-appreciated aspect of our constant 'forgetting' of the building syndrome of our Earth's symptomatology. I make use of my own theory of the 'organizing gestalt' and the thinking of Maturana, Ingold and Colman to offer a framework for the consideration of the uncanny links between what we know about vanishing biodiversity, broken ecosystems and the breaking down of previously integrated Earth systems and the breaking down of our ways of thinking about our relationships with the more-than-human-world...

BACKGROUND: Atrial flutter is a rare condition in pediatrics that usually occurs as a late complication after surgery for congenital heart diseases, although it can also appear in structurally normal hearts. CLINICAL CASES: We conducted a retrospective study of cases of atrial flutter with no structural heart disease diagnosed in a pediatric population (between 0 and 15 years of age) during 2015-2021 in a tertiary hospital. A total of seven cases were diagnosed, with a clear predominance of males (6/7)...

INTRODUCTION: Untreated, severe, symptomatic aortic stenosis is associated with an ominous diagnosis without intervention. This study aims to determine the impact of the COVID-19 pandemic on the mortality of patients with severe stenosis during the first wave and compare it with the same period last year. METHODS: All patients who went to the hospitals in a spanish region during the first wave, and in the same period of previous year, were analysed using Artificial Intelligence-based software, evaluating the mortality of patients with severe aortic stenosis with and without COVID-19 during the pandemic and the pre-COVID era...

The COVID-19 pandemic has imposed several dilemmas for managers in the public sector, with school reopening being among the most complex decisions. The present article presents a microsimulation model of the pandemic course considering various scenarios within the confines of a classroom in the city of Belo Horizonte, Brazil. For that, a susceptible-infectious-recovered (SIR) model was integrated with a random graph model, associating epidemiological characteristics with sociometric and sociodemographic factors...

INTRODUCTION: Predominant polarity (PP) has been proposed as a specifier of bipolar disorder (BD) due to its relationship with clinical and prognostic variables. It is possible that this is due to a different underlying neurobiology, in such a way that the changes found by structural nuclear magnetic resonance imaging (sMRI) in BD are different and specific. OBJECTIVES: To explore findings of structural neuroimaging in patients with BD type I (BD-I) according to PP...

OBJECTIVE: To evaluate the clinical and radiological results of a series of patients with a glenoid bone defect treated by reverse total shoulder arthroplasty associated with a bone graft stabilized with a trabecular titanium glenoid component (Axioma SMR Lima®). MATERIAL AND METHODS: Retrospective descriptive study of 16 consecutive patients with an average age of 68.2years. In 13 cases they were primary arthroplasties and in 3 revision ones. The data included in the study were obtained by reviewing the clinical history...

The pandemic occasioned by COVID-19 has caused, as a sudden and unpredictable need, the introduction of teleworking in the productive systems of most of the countries. Many States have had to resort to old and outdated norms that did not assume the few guarantees of the existing international and supranational instruments. However, other countries have taken advantage of the health emergency situation to reform and update their telework regulations. The purpose of this contribution is to analyze the new regulations that emerged during the pandemic and to carry out a general assessment of their contents to check if they are adapted to the demands and recommendations that, in a digital society, should characterize teleworking...

During the SARS-CoV-2 pandemic, there was a marked requirement for critical care beds, supplies and trained professionals to assist patients with severe respiratory failure.

Resumen:Este estudio se enfoca en cómo un grupo de inmigrantes originarios del estado de Yucatán, en México, y quienes viven en el sur de California, atienden las enfermedades que les aquejan y cómo articulan sus prácticas de atención con sus condiciones socioeconómicas, su estatus migratorio y acceso a los servicios de salud institucionales. La metodología elegida fue de corte cualitativo, a través de entrevistas se recopilaron datos etnográficos analizados con el software MAXQDA12. Las modalidades de las trayectorias en la búsqueda de atención son complejas al ser articulaciones a través de las cuales los entrevistados enfrentan las barreras estructurales para acceder a servicios médicos, y por constituirse al mismo tiempo como una síntesis dinámica de los sistemas de conocimiento científico y del saber popular...

INTRODUCTION: Bipolar disorder (BD) has been associated with a decrease in white matter integrity. Diffusion tensor imaging (DTI) studies have enabled these changes to be elucidated with higher quality. Due to BD's high heritability, some studies have been conducted in relatives of BD patients looking at white matter integrity, and have found that structural connectivity may also be affected. This alteration has been proposed as a potential BD biomarker of vulnerability. However, there are few studies in children and adolescents...

INTRODUCTION: Lithium treatment of bipolar disorder (BD) has been associated with less cognitive impairment and fewer changes in structural brain anatomy compared to other treatments. However, the studies are heterogeneous and few assess whether these effects are related. The objective of this study was to evaluate and relate cognitive performance and structural neuroanatomy in patients treated with and without lithium. METHODS: Cross-sectional study that included 48 subjects with BD-I, of which 22 were treated with lithium and 26 without lithium...
