ABSTRACT

DNA polymerase (pol) kappa is a Y-family translesion DNA polymerase conserved throughout all domains of life. Pol kappa is special6 ized for the ability to copy DNA containing minor groove DNA adducts, especially N2-dG adducts, as well as to extend primer termini containing DNA damage or mismatched base pairs. Pol kappa generally cannot copy DNA containing major groove modifications or UV-induced photoproducts. Pol kappa can also copy structured or non-B-form DNA, such as microsatellite DNA, common fragile sites, and DNA containing G quadruplexes. Thus, pol kappa has roles both in maintaining and compromising genomic integrity. The expression of pol kappa is altered in several different cancer types, which can lead to genome instability. In addition, many cancer-associated single-nucleotide polymorphisms have been reported in the POLK gene, some of which are associated with poor survival and altered chemotherapy response. Because of this, identifying inhibitors of pol kappa is an active area of research. This review will address these activities of pol kappa, with a focus on lesion bypass and cellular mutagenesis.

ABSTRACT

Este consenso fue ideado por el Director del Programa Nacional de Prevención Cardiovascular del M.S P. y B.S. (Paraguay) a raíz de que se necesitaba un documento actualizado que sirva como guía a los profesionales de la salud de todos los niveles de atención incluyendo a las diferentes especialidades, que tratan la hipertensión arterial y sus complicaciones agudas y crónicas. A través del convenio entre el Programa Nacional de Prevención Cardiovascular y la Sociedad Paraguaya de Cardiología de realizar actualizaciones de las Guías o documentos para difusión de manejo de patologías cardiovasculares y factores de riesgo asociados, se ha decidido elaborar y lanzar este material, que será utilizado como guía oficial en todo el territorio nacional. Con mesas de trabajo de varios días y la colaboración de representantes de sociedades científicas afines y asesores internacionales se ha logrado esta guía. Se presentan recomendaciones para facilitar el manejo de los pacientes con hipertensión arterial y sus complicaciones, con el propósito de disminuir la morbimortalidad cardiovascular. Han sido elaboradas según las evidencias científicas y conocimiento de expertos, con un enfoque práctico y sencillo. Todos los participantes aprobaron las decisiones finales. Los autores reconocen que la publicación y difusión de directrices serán siempre una guía práctica y que permitirá a los médicos ampliar los conocimientos con las recomendaciones propuestas, detectar precozmente el daño de órganos blancos y mejorar la calidad de vida de los pacientes hipertensos.


This consensus was conceived by the Director of the National Program of Cardiovascular Prevention of the M.S P. y B.S. (Ministry of Public Health and Social Welfare, Paraguay) because an updated document was necessary as a guide for health professional of all care levels including different specialties that treat arterial hypertension and its acute and chronic complications. Through this consensus between the National Program of Cardiovascular Prevention and the Paraguayan Cardiology Society of updating Guides or documents for the dissemination of the management of cardiovascular pathologies and associated risk factors it was decided to elaborate and launch this material that will be used as an official guide in the national territory. This guide was achieved after working tables held during several days and the collaboration of representatives of related scientific societies and international advisers. Recommendations for facilitating the management of patients with arterial hypertension and its complications are presented in order to reduce the cardiovascular morbidity and mortality. They have been elaborated according to scientific evidence and knowledge of experts with a practical and simple approach. All the participants approved the final decisions. The authors recognize that the publications and dissemination of guidelines will always be a practical guide that will allow physicians to increase their knowledge with the proposed recommendation in order to early detect the damage of target organs and improve the quality of life of the hypertensive patients.

ABSTRACT

Background: Cardiovascular diseases are the current leading causes of death and disability globally. Objective: To assess the effects of a basic educational program for cardiovascular prevention in an unselected outpatient population. Methods: All participants received an educational program to change to a healthy lifestyle. Assessments were conducted at study enrollment and during follow-up. Symptoms, habits, ATP III parameters for metabolic syndrome, and American Heart Association’s 2020 parameters of cardiovascular health were assessed. Results: A total of 15,073 participants aged ≥ 18 years entered the study. Data analysis was conducted in 3,009 patients who completed a second assessment. An improvement in weight (from 76.6 ± 15.3 to 76.4 ± 15.3 kg, p = 0.002), dyspnea on exertion NYHA grade II (from 23.4% to 21.0%) and grade III (from 15.8% to 14.0%) and a decrease in the proportion of current active smokers (from 3.6% to 2.9%, p = 0.002) could be documented. The proportion of patients with levels of triglycerides > 150 mg/dL (from 46.3% to 42.4%, p < 0.001) and LDL cholesterol > 100 mg/dL (from 69.3% to 65.5%, p < 0.001) improved. A ≥ 20% improvement of AHA 2020 metrics at the level graded as poor was found for smoking (-21.1%), diet (-29.8%), and cholesterol level (-23.6%). A large dropout as a surrogate indicator for low patient adherence was documented throughout the first 5 visits, 80% between the first and second assessments, 55.6% between the second and third assessments, 43.6% between the third and fourth assessments, and 38% between the fourth and fifth assessments. Conclusion: A simple, basic educational program may improve symptoms and modifiable cardiovascular risk factors, but shows low patient adherence. .


Fundamentos: As doenças cardiovasculares são, atualmente, as maiores causas de óbito e incapacitação em todo o mundo. Objetivos: Avaliar os efeitos de um programa educativo básico para prevenção cardiovascular em uma população de pacientes ambulatoriais não selecionados. Métodos: Todos os participantes frequentaram um programa educativo de mudança para um estilo de vida saudável. Foram realizadas avaliações à admissão no estudo e durante o acompanhamento. Foram avaliados sintomas, hábitos, parâmetros do ATP III para síndrome metabólica e parâmetros da American Heart Association 2020 para saúde cardiovascular. Resultados: Foram incluídos no estudo 15.073 participantes com idade ≥ 18 anos. Foi feita a análise de dados dos 3.009 pacientes que completaram a segunda avaliação. Foram documentados perda de peso (de 76,6 ± 15,3 para 76,4 ± 15,3 kg, p = 0,002), melhora da dispneia aos esforços graus II-NYHA (de 23,4% para 21,0%) e III (de 15,8% para 14,0%), e redução na proporção de fumantes ativos atuais (de 3,6% para 2,9%, p = 0,002). Houve melhora na proporção de pacientes com níveis de triglicérides > 150 mg/dL (de 46,3% para 42,4%, p < 0,001) e de colesterol LDL > 100 mg/dL (de 69,3% para 65,5%, p < 0,001). Houve melhora ≥ 20% na métrica AHA 2020 no nível classificado como ruim para tabagismo (-21,1%), alimentação (-29,8%), e nível de colesterol (23,6%). Foi documentada grande evasão como indicador substituto para baixa adesão de paciente nas primeiras 5 consultas, sendo 80% entre a primeira e a segunda avaliação, 55,6% entre a segunda e a terceira, 43,6% entre a terceira e a quarta, e 38% entre a quarta e a quinta. Conclusão: Um programa educativo básico e simples pode melhorar os sintomas e fatores de risco cardiovasculares modificáveis, mas conta com pouca adesão por parte dos pacientes. .
