Impact of COVID-19 on liver disease: From the experimental to the clinic perspective.

Coronavirus disease 2019 (COVID-19) has caused a global pandemic unprecedented in over a century. Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a predominantly respiratory infection, various degrees of liver function abnormalities have been reported. Pre-existing liver disease in patients with SARS-CoV-2 infection has not been comprehensively evaluated in most studies, but it can critically compromise survival and trigger hepatic decompensation. The collapse of the healthcare services has negatively impacted the diagnosis, monitoring, and treatment of liver diseases in non-COVID-19 patients. In this review, we aim to discuss the impact of COVID-19 on liver disease from the experimental to the clinic perspective.

Enfermedad de Wilson

[EN] Wilson's disease (WD) is an uncommon hereditary disorder caused by a deficiency in the ATP7B transporter. The protein codified by this gene facilitates the incorporation of the copper into ceruloplasmin. Therefore, WD accumulates copper primary in the liver and secondary in other organs, such as the central nervous system. It represents a wide spectrum of disease, ranging from being asymptomatic in some patients to promote an acute liver failure in others. The diagnosis requires a combination of clinical signs and symptoms, as well as some diagnostic tests such as the measurement of serum ceruloplasmin, the urinary excretion of copper, the liver biopsy or the genetic testing. The treatment must be maintained lifelong and includes some drugs such as chelating agents (penicillamine and trientine) and inhibitors of the copper absorption (zinc salts). Lastly, the liver transplant should be an option for patients with end-stage liver disease.[ES] La enfermedad de Wilson (EW) es una enfermedad hereditaria rara causada por la deficiencia del trasportador ATP7B. La proteína codificada por este gen facilita la incorporación del cobre a la ceruloplasmina. Por lo tanto, la EW condiciona una acumulación de cobre principalmente en el hígado y en el sistema nervioso central. Su espectro clínico es amplio, desde pacientes asintomáticos hasta enfermedad hepática crónica, fallo hepático agudo o síntomas neurológicos. El diagnóstico se establece mediante la combinación de signos y pruebas diagnósticas como medición de ceruloplasmina, excreción urinaria de cobre, cuantificación de cobre en tejido seco y estudio genético. Las terapias farmacológicas deben ser mantenidas de por vida e incluyen fármacos quelantes del cobre como la D-penicilamina o la trientina e inhibidores de la absorción de cobre como las sales de zinc. El trasplante hepático debe ser una opción en la enfermedad hepática terminal.Peer reviewe

Wilson's disease: Revisiting an old friend

Wilson's disease (WD) is a rare condition caused by copper accumulation primarily in the liver and secondly in other organs, such as the central nervous system. It is a hereditary autosomal recessive disease caused by a deficiency in the ATP7B transporter. This protein facilitates the incorporation of copper into ceruloplasmin. More than 800 mutations associated with WD have been described. The onset of the disease frequently includes manifestations related to the liver (as chronic liver disease or acute liver failure) and neurological symptoms, although it can sometimes be asymptomatic. Despite it being more frequent in young people, WD has been described in all life stages. Due to its fatal prognosis, WD should be suspected in all patients with unexplained biochemical liver abnormalities or neurological or psychiatric symptoms. The diagnosis is established with a combination of clinical signs and tests, including the measurement of ceruloplasmin, urinary copper excretion, copper quantification in liver biopsy, or genetic assessment. The pharmacological therapies include chelating drugs, such as D-penicillamine or trientine, and zinc salts, which are able to change the natural history of the disease, increasing the survival of these patients. In some cases of end-stage liver disease or acute liver failure, liver transplantation must be an option to increase survival. In this narrative review, we offer an overview of WD, focusing on the importance of clinical suspicion, the correct diagnosis, and treatment

Ciencia y persuasión social en la medicalización de la infancia en España, siglos XIX-XX Science and social persuasion in the medicalization of childhood in 19th- and 20th-century Spain

Este trabajo indaga la conversión en rutinaria de la visita del médico de niños en España. Estudia la sustitución de modelos de atención al embarazo, parto y crianza, tradicionalmente opacos para varones y objeto de cuidados mediante agentes populares, por otros accesibles a la medicina académica. A partir de la situación existente a nivel popular en el último tercio del siglo XIX, exploramos la repercusión de campañas de divulgación científica - entendidas como crítica sin cuartel a lo que se construyó como cultura popular - y la proliferación de dispositivos asistenciales gratuitos. La oferta de vigilancia sobre la alimentación de lactantes permitió familiarizar a las madres con la asistencia facultativa en la enfermedad, hasta que, en la segunda mitad del siglo XX, la Pediatría se centró preferentemente en las patologías y la Puericultura dejó de ser especialidad médica para convertirse en identidad profesional subalterna.<br>The article explores how childhood visits to doctors first became routine in Spain. The introduction of new models of prenatal care, childbirth, and childrearing required the extension of academic medicine into a terrain traditionally occupied by practitioners of popular medicine. Focusing on the status quo for most of the population in the final third of the nineteenth century, the study examines the repercussion of the era's scientific outreach campaigns (expressions of harsh criticism of what popular culture had constructed) and the spread of free health assistance. In particular, it highlights how attention to the nutritional needs of nursing mothers helped these women gain familiarity with the medical assistance available in the case of illness - so much so that by the second half of the twentieth century, the issues of health education and promotion had been relegated to a secondary plane within the medical profession

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P &lt; 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
