Ethanol is one of the most widely used recreational substances in the world and due to its ubiquitous use, ethanol abuse has been the cause of over 3.3 million deaths each year. In addition to its effects, ethanol's primary metabolite, acetaldehyde, is a carcinogen that can cause symptoms of facial flushing, headaches, and nausea. How strongly ethanol or acetaldehyde affects an individual depends highly on the genetic polymorphisms of certain genes. In particular, the genetic polymorphisms of mitochondrial aldehyde dehydrogenase, ALDH2, play a large role in the metabolism of acetaldehyde. Thus, it is important to characterize how genetic variations can lead to different exposures and responses to ethanol and acetaldehyde. While the pharmacokinetics of ethanol metabolism through alcohol dehydrogenase have been thoroughly explored in previous studies, in this paper, we combined a base physiologically-based pharmacokinetic (PBPK) model with a whole-body genome-scale model (WBM) to gain further insight into the ealized form of PBPK modelling that can push the boundaries of precision medicine.Since the 2015 to 2016 outbreak in America, Zika virus (ZIKV) infected almost 900,000 patients. This international public health emergency was mainly associated with a significant increase in the number of newborns with congenital microcephaly and abnormal neurologic development, known as congenital Zika syndrome (CZS). Furthermore, Guillain-Barré syndrome (GBS), a neuroimmune disorder of adults, has also been associated with ZIKV infection. Currently, the number of ZIKV-infected patients has decreased, and most of the cases recently reported present as a mild and self-limiting febrile illness. However, based on its natural history of a typical example of reemerging pathogen and the lack of specific therapeutic options against ZIKV infection, new outbreaks can occur worldwide, demanding the attention of researchers and government authorities. Here, we discuss the clinical spectrum and immunopathological mechanisms underlying ZIKV-induced neurological manifestations. Several studies have confirmed the tropism of ZIKV for neural progenitor stem cells by demonstrating the presence of ZIKV in the central nervous system (CNS) during fetal development, eliciting a deleterious inflammatory response that compromises neurogenesis and brain formation. Of note, while the neuropathology of CZS can be due to a direct viral neuropathic effect, adults may develop neuroimmune manifestations such as GBS due to poorly understood mechanisms. Antiganglioside autoantibodies have been detected in multiple patients with ZIKV infection-associated GBS, suggesting a molecular mimicry. However, further additional immunopathological mechanisms remain to be uncovered, paving the way for new therapeutic strategies.The SARS-CoV-2 Spike protein needs to be in an open-state conformation to interact with ACE2 to initiate viral entry. We utilise coarse-grained normal mode analysis to model the dynamics of Spike and calculate transition probabilities between states for 17081 variants including experimentally observed variants. Our results correctly model an increase in open-state occupancy for the more infectious D614G via an increase in flexibility of the closed-state and decrease of flexibility of the open-state. We predict the same effect for several mutations on glycine residues (404, 416, 504, 252) as well as residues K417, D467 and N501, including the N501Y mutation recently observed within the B.1.1.7, 501.V2 and P1 strains. This is, to our knowledge, the first use of normal mode analysis to model conformational state transitions and the effect of mutations on such transitions. The specific mutations of Spike identified here may guide future studies to increase our understanding of SARS-CoV-2 infection mechanisms and guide public health in their surveillance efforts.

Worldwide, nearly 800,000 individuals die by suicide each year; however, longitudinal prediction of suicide attempts remains a major challenge within the field of psychiatry. The objective of the present research was to develop and evaluate an evidence-based suicide attempt risk checklist [i.e., the Durham Risk Score (DRS)] to aid clinicians in the identification of individuals at risk for attempting suicide in the future.

Three prospective cohort studies, including a population-based study from the United States [i.e., the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) study] as well as 2 smaller US veteran cohorts [i.e., the Assessing and Reducing Post-Deployment Violence Risk (REHAB) and the Veterans After-Discharge Longitudinal Registry (VALOR) studies], were used to develop and validate the DRS. From a total sample size of 35,654 participants, 17,630 participants were selected to develop the checklist, whereas the remaining participants (N = 18,024) were used to validate it.uggest that the DRS represents a significant advancement in suicide risk prediction over traditional clinical assessment approaches. While more work is needed to independently validate the DRS in prospective studies and to identify the optimal methods to assess the constructs used to calculate the score, our findings suggest that the DRS is a promising new tool that has the potential to significantly enhance clinicians' ability to identify individuals at risk for attempting suicide in the future.

El tratamiento estándar de la perforación intestinal es quirúrgico. Sin embargo, se sugiere que la inserción de un drenaje en el abdomen puede ser efectivo para tratar esta afección. Se resumen los resultados de una revisión sistemática Cochrane que compara la efectividad del drenaje peritoneal con la de la laparotomía en neonatos con enterocolitis necrosante perforada.Necrotizing enterocolitis is common in preterm newborns, with consequent intestinal perforation. The standard treatment for intestinal perforation is surgery. However, it is suggested that inserting a drain into the abdomen may be effective in treating this condition. This document summarizes the results of a Cochrane systematic review comparing the effectiveness of peritoneal drainage with laparotomy in neonates with perforated necrotizing enterocolitis.La mucopolisacaridosis es un grupo heterogéneo de enfermedades que se caracterizan por la acumulación lisosomal de sustancias intermedias del metabolismo de los mucopolisacáridos o glucosaminoglucanos. El trastorno respiratorio que caracteriza a los pacientes con mucopolisacaridosis es la enfermedad pulmonar restrictiva crónica, por lo que la rehabilitación pulmonar, cuyo objetivo es mejorar los síntomas respiratorios, y la fisioterapia respiratoria, mejorarán la ventilación pulmonar y la biomecánica respiratoria deteriorada. Es necesario el seguimiento por el neumólogo infantil, quien cuantificará la función pulmonar y vigilará los síntomas de obstrucción nocturna y de restricción pulmonar con ayuda de estudios como la espirometría, la pletismografía y la prueba de la caminata de 6 minutos, por mencionar algunas. También es muy importante realizar un programa individualizado de técnicas de fisioterapia respiratoria y de ejercicios. Todo lo anterior, con el objetivo de evaluar la función pulmonar como un marcfollowed for evaluating lung function as a marker of response to the use of any of the therapies indicated in mucopolysaccharidosis.

La toxoplasmosis congénita continúa siendo un problema de salud pública. Aun cuando existen guías plenamente divulgadas y conocidas, se observa poca implementación de ellas en algunas instituciones de salud y una inadecuada interpretación de las pruebas serológicas en las gestantes. Esto puede generar falta de captación y tratamiento en embarazadas con primoinfección por Toxoplasma gondii.

Se reportan dos casos de toxoplasmosis congénita, uno de ellos con desenlace fatal. En ambos no se siguieron las guías de práctica clínica, lo cual conllevó un diagnóstico tardío y, en consecuencia, un manejo en condiciones inapropiadas con daños graves.

La toxoplasmosis es una infección congénita aún prevalente en algunos países, con secuelas graves, discapacidad neurológica y riesgo de daño ocular, incluso tardío. Además, existen algunas variedades de cepas de T. gondii con un comportamiento más agresivo en Latinoamérica, lo cual empeora la presentación de los casos e incluye mayor riesgo de muerte.

Congenital toxoplasmosis continues to be a public health problem.
