Consenso mexicano sobre dolor torĂĄcico no cardiaco
IntroducciĂłn: Dolor torĂĄcico no cardĂaco (DTNC) se define como un sĂndrome clĂnico caracte-rizado por dolor retroesternal semejante a la angina de pecho, pero de origen no cardiaco ygenerado por enfermedades esofĂĄgicas, osteomusculares, pulmonares o psiquiĂĄtricas.Objetivo: Presentar una revisiĂłn consensuada basada en evidencias sobre definiciĂłn, epidemio-logĂa, fisiopatologĂa, diagnĂłstico y opciones terapĂ©uticas para pacientes con DTNC.MĂ©todos: Tres coordinadores generales realizaron una revisiĂłn bibliogrĂĄfica de todas las publi-caciones en inglĂ©s y espaËnol sobre el tema y elaboraron 38 enunciados iniciales divididosen tres categorĂas principales: 1) definiciones, epidemiologĂa y fisiopatologĂa; 2) diagnĂłstico,y 3) tratamiento. Los enunciados fueron votados (3 rondas) utilizando el sistema Delphi, y losque alcanzaron un acuerdo > 75% fueron considerados y calificados de acuerdo con el sistemaGRADE.
Resultados y conclusiones: El consenso final incluyĂł 29 enunciados Todo paciente que debutacon dolor torĂĄcico debe ser inicialmente evaluado por un cardiĂłlogo. La causa mĂĄs comĂșn deDTNC es la enfermedad por reflujo gastroesofĂĄgico (ERGE). Como abordaje inicial, si no existensĂntomas de alarma, se puede dar una prueba terapĂ©utica con inhibidor de bomba de pro-tones (IBP) por 2-4 semanas. Si hay disfagia o sĂntomas de alarma, se recomienda hacer unaendoscopia. La manometrĂa de alta resoluciĂłn es el mejor mĂ©todo para descartar trastornosmotores espĂĄsticos y acalasia. La pHmetrĂa ayuda a demostrar exposiciĂłn esofĂĄgica anormal alĂĄcido. El tratamiento debe ser dirigido al mecanismo fisiopatolĂłgico, y puede incluir IBP, neu-romoduladores y/o relajantes de mĂșsculo liso, intervenciĂłn psicolĂłgica y/o terapia cognitiva,y ocasionalmente cirugĂa o terapia endoscĂłpica.
ABSTRACT
Introduction: Non-cardiac chest pain is defined as a clinical syndrome characterized by retros-ternal pain similar to that of angina pectoris, but of non-cardiac origin and produced byesophageal, musculoskeletal, pulmonary, or psychiatric diseases.Aim: To present a consensus review based on evidence regarding the definition, epidemiology,pathophysiology, and diagnosis of non-cardiac chest pain, as well as the therapeutic options forthose patients.
Methods: Three general coordinators carried out a literature review of all articles published inEnglish and Spanish on the theme and formulated 38 initial statements, dividing them into 3 maincategories: (i) definitions, epidemiology, and pathophysiology; (ii) diagnosis, and (iii) treatment.The statements underwent 3 rounds of voting, utilizing the Delphi system. The final statementswere those that reached > 75% agreement, and they were rated utilizing the GRADE system.Results and conclusions: The final consensus included 29 statements. All patients presentingwith chest pain should initially be evaluated by a cardiologist. The most common cause ofnon-cardiac chest pain is gastroesophageal reflux disease. If there are no alarm symptoms, the initial approach should be a therapeutic trial with a proton pump inhibitor for 2-4 weeks. Ifdysphagia or alarm symptoms are present, endoscopy is recommended. High-resolution mano-metry is the best method for ruling out spastic motor disorders and achalasia and pH monitoringaids in demonstrating abnormal esophageal acid exposure. Treatment should be directed at thepathophysiologic mechanism. It can include proton pump inhibitors, neuromodulators and/orsmooth muscle relaxants, psychologic intervention and/or cognitive therapy, and occasionallysurgery or endoscopic therapy

Vocabulario de la sociedad civil, la ruralidad y los movimientos sociales en América Latina
El Vocabulario de la Sociedad Civil, la Ruralidad y los
Movimientos Sociales en América Latina tiene como
objetivo desarrollar vocablos relacionados con temas
de gran trascendencia para la vida colectiva de la
poblaciĂłn Latinoamericana; pretende introducir a
estudiantes, personas del åmbito académico y activistas
en la comprensiĂłn de estas categorĂas de anĂĄlisis.
A través de la mirada de 70 especialistas que
participaron en este vocabulario, es posible comprender
muchos de los términos que se utilizan dentro de
la investigaciĂłn social y ĂĄreas relacionadas con las
ciencias polĂticas, ambientales y rurales, a partir de
una mayor explicaciĂłn y detalle. Es por ello que se
inserta este trabajo desde una mirada colectiva y
amplia de los conceptos que se exponen.
En este libro podrĂĄ encontrar las ideas de varios autores
y autoras de distintas universidades, con una visiĂłn
multi, inter y transdisciplinaria. El esfuerzo que se
realizó para conjuntar varios términos y analizar su
compleja red de interpretaciones, permitirĂĄ que este
manuscrito pueda ser consultado por estudiantes,
personas del ĂĄmbito cientĂfico-acadĂ©mico, y ciudadanĂa;
porque contiene el estado del arte, la historia del
paulatino avance de mĂșltiples conceptos y su vigencia

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and lowâmiddle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of âsingle-useâ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for lowâmiddle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both highâ and lowâmiddleâincome countries

Memoria del segundo congreso internacional sobre paz, democracia y desarrollo.
Los textos presentados reflejan el espĂritu del encuentro que los reuniĂł. Juntos expresan un ejercicio de interdisciplinariedad, pluralidad, debate de ideas, y difusiĂłn de diferentes puntos de vista, sobre temas relacionados con la cultura de paz, la violencia, el desarrollo y la democracia. Y contribuyen a la comprensiĂłn sobre los lĂmites, heterogeneidades y lagunas del proceso de instauraciĂłn y consolidaciĂłn de las instituciones democrĂĄticas de los paĂses de AmĂ©rica Latina. TambiĂ©n analizan la marginaciĂłn, la desigualdad, la inequidad, la violencia, la inseguridad cotidiana y otros asuntos relacionados con la falta de recursos y opciones para los habitates de la regiĂłn
