Grambank reveals the importance of genealogical constraints on linguistic diversity and highlights the impact of language loss

While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here we outline the Grambank database. With over 400,000 data points and 2,400 languages, Grambank is the largest comparative grammatical database available. The comprehensiveness of Grambank allows us to quantify the relative effects of genealogical inheritance and geographic proximity on the structural diversity of the world's languages, evaluate constraints on linguistic diversity, and identify the world's most unusual languages. An analysis of the consequences of language loss reveals that the reduction in diversity will be strikingly uneven across the major linguistic regions of the world. Without sustained efforts to document and revitalize endangered languages, our linguistic window into human history, cognition and culture will be seriously fragmented.Genealogy versus geography Constraints on grammar Unusual languages Language loss Conclusio

Las personas con enfermedad terminal y la necesidad de cuidados paliativos: una deuda pendiente de los servicios de salud

On top of all competences that a healthcare professional should have achieved during his/her training, palliative care is a growing need for patients from different age groups affected with cancer, cardiovascular diseases, degenerative conditions, and the like. Palliative care is a huge challenge for healthcare services, because this requires adequate teamwork, human resources and adequately functioning systems. Management, public health, service integration, ethical dilemmas, and ethical issues are the main barriers that physicians taking care of terminally ill patients must deal with. One of our main strategies for tackling this situation is to consolidate educational programs, so healthcare professionals may become empowered with knowledge; so, they may disclose the need for humanizing healthcare of terminally ill subjects.Los cuidados paliativos, además de ser parte de las competencias que debería haber adquirido un profesional de la salud durante su formación, son una necesidad en crecimiento para pacientes de diferentes grupos etarios, ya sea para enfermedades oncológicas, cardiovasculares, degenerativas, entre otras. Se consideran un reto para los servicios de salud por ser cuidados complejos, que requieren de trabajo en equipo, recursos humanos y sistemas que funcionen adecuadamente. Los aspectos de gestión, salud pública, integración de servicios, dilemas éticos y aspectos legales en transición son las principales barreras a las que se enfrentan los profesionales que atienden personas con enfermedad terminal. Una de las principales armas que tenemos es consolidar programas educativos para empoderar con conocimiento a los profesionales y, de esta forma, que hagan notar la necesidad del manejo humano de la salud de personas con enfermedades terminales

Prognostic performance of neutrophil/lymphocyte ratio and platelet/lymphocyte ratio for mortality in patients with acute stroke

Objective: To evaluate the prognostic performance of the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) for mortality in patients with acute stroke treated at a Peruvian hospital. Design: Retrospective cohort study. Setting: Tertiary care hospital. Patients: Patients aged ≥18 years with a diagnosis of acute stroke and admitted to the hospital from May 2019 to June 2021. Interventions: None. Main variables of interests: Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and mortality. Results: A total of 165 patients were included. The mean age was 66.1 ± 14.2 years, and 59.4% were male. Only NLR had a performance superior to 0.7 (AUC: 0.75; 95%CI: 0.65–0.85), and its elevated levels were associated with an increased risk of mortality (aRR: 3.66; 95%CI: 1.77–8.85) after adjusting for confounders. Conclusion: The neutrophil-to-lymphocyte ratio has an acceptable prognostic performance for mortality in patients with acute stroke. Its use may be considered to stratify patients’ risk and to consider timely alternative care and management.Revisión por pare

Consensus statement on integral management of the newborn with hypoxic-ischemic encephalopathy Consenso sobre manejo integral del neonato con encefalopatía hipóxico isquémica consensus

Neonatal encephalopathy secondary to birth asphyxia, the hypoxic ischemic encephalopathy, remains a major cause of postnatal death and neurological sequelae worldwide. Supportive therapy has been the mainstay of treatment. Recently series of multicenter clinical trials show the benefits of therapeutic hypothermia in this high risk population. The International Liaison Committee on Resuscitation (ILCOR) has recommended hypothermia as a standard of care and a beneficial therapy using the protocols followed in large clinical trials. Our objective was to develop a practical guide to be used at a national level in Chile, compatible with published protocols and standardized on an international basis, practical and compatible with the country's situation, and considering an integral management of the asphyxiated neonates, rescue and neuroprotective therapies. In summary, to establish rescue therapies, with the aim objective of support measures that promote cerebral and systemic oxygenation/p
