Larrea divaricata a native Argentine plant with potential activity against SARS-CoV-2? / ¿Larrea divaricata una planta nativa argentina con actividad potencial sobre SARS-CoV-2?

Larrea divaricata Cav. is an autochthonous South American plant popularly used in inflammatory and infectious diseases with reported anti - inflammatory, immunomodulatory, antimicrobial and antioxidant activities. Covid - 19 is an infection ca used by the severe acute respiratory syndrome coronavirus 2 (SARS - CoV - 2). This virus can cause pneumonia and even death in about 5% of the cases. The objective of the article was to demonstrate, through a literature review, that L. divaricata has sufficie nt attributes to be assayed against SARS - CoV - 2. For this, the chemical composition, reported activities and docking studies were taken into account. This review demonstrated that the plant extracts are capable of inhibiting the proliferation of fungi, bact eria and viruses and that they exert anti - inflammatory and immunomodulatory actions in different " in vitro " and " in vivo " models. These results suggest that the plant is a good candidate to be studied for the prevention and/or treatment of SARS - CoV - 2.

El Covid - 19 es una infección causada por una cepa de coronavirus, SARS - CoV - 2 (coronavirus tipo 2 causante del síndrome respiratorio agudo severo). Este virus puede originar neu monía e incluso la muerte en alrededor del 5% de los casos. Nuestro objetivo fue demostrar, a través de una revisión bibliográfica, que esta planta tiene atributos suficientes para ser ensayada en estudios contra SARS - CoV - 2. Se tuvo en cuenta la composici ón química, los antecedentes científicos y los estudios de acoplamiento molecular. Esta revisión permitió demostrar que extractos de la planta son capaces de inhibir la proliferación de hongos, bacterias y virus y que presentan acción anti - inflamatoria en diferentes modelos " in vitro " e " in vivo ", lo que los hace candidatos a ser estudiados en la prevención y/o tratamiento de la infección contra SARS - CoV - 2.

Vicenin-2 and vitexin participate in the in vitromodulation of the anti-inflammatory and antioxidant activities exerted by two Urtica circularisextracts / Participación de vicenina-2 y vitexina en la modulación de la actividad anti-inflamatoria in vitro y en la actividad antioxidante de dos extractos de Urtica circularis

Urtica circularis is an Argentinean species traditionally used to treat inflammation symptoms and oxidative stress-related diseases. Considering the uses in folk medicine, the purpose of this work was to evaluate and compare the anti-inflammatory and antioxidant activities of two different U. circularisextracts. The contribution of vicenin-2 and vitexin, two compounds identified in the phytochemical analysis, in the biological activity of the extracts was evaluated. The anti-inflammatory activity of the extracts and the isolated compounds was tested on lipopolysaccharide (LPS)-stimulated macrophages, while the antioxidant activity was evaluated through the 2,2 ́ diphenyl-1-picrylhydrazyl (DPPH) radical and 2,2 ́-azinobis(3-ethylbenzthiazoline-6-sulfonic acid) diammonium salt (ABTS) scavenging activities. The popular uses of both extracts were validated, i.e., the use of U. circularis ethanol extract for the treatment of inflammation, and the use of the aqueous extract to treat oxidative stress related-diseases. The differences in the biological activities observed between the extracts are probably due to qualitative and/or quantitative differences in the chemical composition and/or the occurrence of synergism between compounds.

Urtica circularis es una especie argentina utilizada para tratar los síntomas de la inflamación y enfermedades relacionadas con el estrés oxidativo. El objetivo de este trabajo fue evaluar y comparar las actividades anti-inflamatoria y antioxidante de dos extractos teniendo en cuenta su uso popular. Además, se analizó la participación de vicenina-2 y vitexina, compuestos identificados en el análisis fitoquímico, en la actividad de los extractos. La actividad anti-inflamatoria fue evaluada en macrófagos activados con lipopolisacárido (LPS). Se midió su actividad antioxidante con los métodos del 1,1,difenil-2-picril-hidrazilo (DPPH) y del ácido2,2 ́azinobis-3 etilbenzotialzolin-6-sulfónico (ABTS). Los usos populares de ambos extractos fueron validados: el extracto etanólico para la inflamación y el extracto acuoso para el tratamiento de enfermedades relacionadas con el estrés oxidativo. Las diferencias en las actividades biológicas observadas entre los extractos están probablemente relacionadas con diferencias cualitativas y/o cuantitativas en su composición química y/o a la presencia de sinergismo entre compuestos

2021 clinical practice guidelines in the evaluation and management of pediatric community-acquired pneumonia

Preface@#The Clinical Practice Guidelines (CPG) for the Diagnosis and Management of Pediatric Community-Acquired Pneumonia (PCAP) was initiated by the Philippine Academy of Pediatric Pulmonologists, Inc. (PAPP) and the Pediatric Infectious Disease Society of the Philippines (PIDSP), in cooperation with Philippine Pediatric Society, Inc. (PPS) way back in 2004. Several CPG updates were then undertaken by the PAPP PCAP CPG Task Force from 2008 to 2016. Clinically-relevant research questions were answered with recent and current recommendations based on evidence from local and international data. The 2021 PCAP CPG initiative was envisioned in March 2018 upon the recommendations of the 2018 PAPP Board for the purpose of updating the evidence in the PCAP CPG 2016 clinical questions. This led to the collaboration of PAPP and PIDSP to develop this CPG. Individual members were identified from each society as content experts to form the Steering Committee along with a clinical epidemiologist and technical writer as review experts. The committee identified the scope and target end user of the CPG as well as additional clinical questions to be included in the 2021 update aside from the questions on the previous CPGs. Selected members from the two societies formed the Technical Working Group (TWG) who did the literature search, appraisal of evidences, and formulation of recommendations. These recommendations were then presented to the stakeholders who became part of the consensus panel. There was no identified conflict of interest among the CPG developers, TWG members and stakeholders. A survey to determine potential competing interests were conducted during the development of this CPG. This initiative was fully funded by the PAPP and PIDSP societies. The 2021 PCAP CPG significantly differs from the previous CPGs in several aspects. First, the current guideline is a consensus between two pediatric societies. Second, much of the literature review has been centered on meta-analyses or systematic reviews instead of individual studies. Finally, appraisal of published literature was based on Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria. Such methodological differences may provide difficulties in defining evolution of care through the years. As identified in the previous CPG updates, there is lack of local data hence most of the evidences gathered came from international studies. The applicability of such data to the local setting needs to be critically assessed for its value and relevance. Corollary to this, several gaps in knowledge are identified and these may serve as a guide for future research.

Internal consistency of the Strengths and Difficulties Questionnaire in Amazonian children / Consistência interna do Questionário de Capacidades e Dificuldades em crianças amazônicas

ABSTRACT OBJECTIVE: To describe the frequency of behavioral problems and the internal consistency of the parent version of the Strengths and Difficulties Questionnaire (SDQ-P) in Amazonian preschool children during the covid-19 pandemic. METHODS: Data from the Maternal and Child Health and Nutrition in Acre (MINA-Brazil) study, a population-based birth cohort in the Western Brazilian Amazon, were used. The SDQ-P was applied in 2021 at the five-year follow-up visit to parents or caregivers of 695 children (49.4% of which were girls). This instrument is a short behavioral screening questionnaire composed of 25 items reorganized into five subscales: emotional symptoms, conduct problems, hyperactivity/inattention, peer relationship problems, and prosocial behavior. Cases of behavioral problems were defined according to the original SDQ cut-offs based on United Kingdom norms. Moreover, cut off points were estimated based on the SDQ-P percentile results of our study sample. Internal consistency was assessed by calculating Cronbach's alpha coefficient and McDonald's omega for each scale. RESULTS: According to the cut-offs based on our studied population distribution, 10% of all children had high or very high total difficulty scores, whereas it was almost twice when the original SDQ cut-offs based on United Kingdom norms, were applied (18%). Differences were also observed in the other scales. Compared to girls, boys showed higher means of externalizing problem and lower means of prosocial behavior. The five-factor model showed a moderate internal consistency of the items for all scales (0.60 ≤ α ≤ 0.40), except for total difficulty scores, which it considered substantial (α > 0.61). CONCLUSIONS: Our results support the usefulness of SDQ in our study population and reinforce the need for strategies and policy development for mental health care in early life in the Amazon.

RESUMO OBJETIVO: Descrever a frequência de problemas de comportamento e a consistência interna da versão para os pais do Questionário de Capacidades e Dificuldades (SDQ-P) em crianças pré-escolares da Amazônia durante a pandemia de covid-19. MÉTODOS: Foram utilizados dados do estudo de saúde e nutrição Materno-Infantil no Acre (MINA-Brasil), uma coorte de nascimentos de base populacional na Amazônia Ocidental Brasileira. O SDQ-P foi aplicado aos pais e cuidadores em 2021 na visita de acompanhamento de cinco anos de 695 crianças (49,4% das quais eram meninas). Esse instrumento é um breve questionário de rastreamento comportamental composto por 25 itens reorganizados em cinco subescalas: sintomas emocionais, problemas de conduta, hiperatividade/desatenção, problemas de relacionamento com colegas e comportamento pró-social. Os casos de problemas de comportamento foram definidos de acordo com os pontos de corte originais do SDQ, baseados nas normas do Reino Unido. Além disso, os pontos de corte foram estimados com base nos percentis dos resultados do SDQ-P da amostra do nosso estudo. A consistência interna foi avaliada pelo cálculo do coeficiente alfa de Cronbach e ômega de McDonald para cada escala. RESULTADOS: De acordo com os pontos de corte baseados na distribuição da população estudada, 10% de todas as crianças apresentaram escores totais de dificuldade elevados ou muito elevados, o que quase dobrou quando os pontos de corte originais do SDQ, baseados nas normas do Reino Unido, foram utilizados (18%). Este estudo também encontrou diferenças nas demais escalas. Comparados às meninas, os meninos apresentaram maiores médias de problemas de externalização e menores médias de comportamento pró-social. O modelo de cinco fatores apresentou consistência interna dos itens moderada para todas as escalas (0,60 ≤ α ≤ 0,40), exceto para a escala de pontuação total de dificuldades, a qual foi considerada substancial (α > 0,61). CONCLUSÕES: Nossos resultados apoiam a utilidade do SDQ em nossa população de estudo e reforçam a necessidade de estratégias e desenvolvimento de políticas para o cuidado em saúde mental no início da vida na Amazônia.

A holistic approach to evaluating Parkinson's disease, using the Delphi method: a linear evaluation index / Un enfoque holístico para evaluar la enfermedad de Parkinson con el método Delphi: un índice evaluativo lineal

ABSTRACT Background: Parkinson's disease (PD) is a chronic disease that presents a multitude of symptoms, with symptoms of both motor and nonmotor nature. The Delphi method is widely used to create consensuses among experts in a field of knowledge. Objective: In order to reach a consensus on the values that should be assigned to the different motor and nonmotor manifestations of Parkinson's disease, a linear evaluation index (LEI) was created. Subsequently, the metric properties of this index were studied. Methods: 120 consecutive patients with a Parkinson's diagnosis were chosen in accordance with the UKPDSBB criteria. The Delphi method was used to reach a consensus among experts regarding the values of each of the manifestations included. Subsequently, the following attributes were analyzed: quality and acceptability of the data; reliability, in terms of internal consistency, reliability index, Cronbach's alpha and standard error of measurement; and validity, in terms of convergent validity and validity for known groups. Results: Twenty-five experts participated. The importance factor did not differ between the first round and the second round (chi-square test). We analyzed the responses that assigned percentage values to the 10 dimensions of the LEI. Both in the first and in the second round, the values of the scattering coefficient Vr were always close to 0. The homogeneity index was 0.36; the corrected-item total correlation values ranged from 0.02 to 0.7; Cronbach's α was 0.69; and the SEM was 4.23 (55.1%). Conclusions: The LEI was obtained through rigorous recommended methodology. The results showed adequate metric properties.

RESUMO Antecedentes: La enfermedad de Parkinson (EP) es una enfermedad crónica que presenta una multitud de síntomas, tanto de naturaleza motora cuanto no motora. El método Delphi se utiliza ampliamente para crear un consenso entre expertos de un campo del conocimiento. Objetivos: Con el fin de llegar a un consenso sobre los valores que deben asignarse a las diferentes manifestaciones motoras y no motoras de la enfermedad de Parkinson, se creó el "Índice de Evaluación Lineal" (linear evaluation index - LEI). Posteriormente, se estudiaron las propiedades métricas de este índice. Métodos: Se eligieron 120 pacientes consecutivos con diagnóstico de Parkinson según los criterios del UKPDSBB. Se utilizó el método Delfos para llegar a un consenso entre los expertos sobre los valores de cada una de las manifestaciones incluidas. Posteriormente, se analizaron los siguientes atributos: Calidad y aceptabilidad de los datos. Fiabilidad: consistencia interna, índice de fiabilidad, alfa de Cronbach y error estándar de medida. Finalmente, Validez: validez convergente y validez para grupos conocidos. Resultados: Participaron 25 expertos, el factor de importancia entre la primera y la segunda rondas (prueba chi-cuadrado), no fue diferente. Analizamos las respuestas que asignaron valores porcentuales a las 10 dimensiones del LEI; tanto en la primera como en la segunda rondas, los valores del coeficiente de dispersión Vr siempre estuvieron cerca de 0. El índice de homogeneidad fue de 0,36; los valores corregidos de correlación ítem-total variaron de 0,02 a 0,7; alpha de Cronbach fue de 0,69. El SEM fue 4,23 (55,1%). Conclusiones: El LEI se ha obtenido siguiendo una rigurosa metodología recomendada. Los resultados han mostrado propiedades métricas adecuadas.

Continuity of Care Challenges for Professional Nursing Practice / Desafíos en la continuidad de cuidados para la práctica profesional de enfermería / Desafios na continuidade de cuidados para a prática profissional de enfermagem

The transformation of health systems to meet the needs of chronic and multi-pathological patients has turned continuity of care into one of the mainstays of care programs and the design of new resources to care for these patients and their families. In this context, nurses' professional practice poses challenges for the three dimensions of continuity of care: relational, informational, and managerial. Faced with these challenges, nursing research is essential for the profession and necessary to promote innovative quality care.

La transformación de los sistemas sanitarios para dar respuesta a las necesidades del paciente crónico y pluripatológico ha situado la continuidad de cuidados como uno de los pilares en los que se basan los programas de atención y el diseño de nuevos recursos para atender a estos pacientes y a sus familias. En este contexto, la práctica profesional de las enfermeras presenta retos y desafíos en las tres dimensiones de la continuidad de cuidados: relacional, informativa y de gestión. Ante estos desafíos, la investigación en enfermería es fundamental para la profesión y necesaria para promover unos cuidados innovadores y de calidad.

New Rules for Teaching in Dental Schools in the COVID-19 Era

ABSTRACT: The crisis caused by COVID-19 has led to the development of strategies for adapting the undergraduate and postgraduate teaching of dentistry to the new situation, as well as guaranteeing the safety of all staff, students, patient s and persons accompanying them.We reviewed a total of 36 documents, including articles and guidelines or recommendations issued by dental schools, scientific societies and other institutions, in order to take stock of the current evidence available about the impact of the COVID-19 pandemic on dental schools. Additional training is required in the management of infectious diseases and the prevention of their transmission. Dental schools must be prepared and implement the necessary measures according to the level of infection risk during face-to-face activities, especially in clinics, while guaranteeing quality teaching and allo wing research to be carried out. Adapting teaching to new technologies is essential for the development of non-classroom training, a s is conducting questionnaires that collect information on crisis management and assessing the stress level of students, faculty and other staff. The incorporation of new technologies in both training and assessment reduces the chances of contagion and enhances student autonomy. Distance learning competencies must be clear to students and be included in the description of the academic programme. We must not forget that the primary objective of teaching is for students to acquire the necessary skills f or their profession. More than ever, the international cooperation of universities in the elaboration of protocols is essential. T hese protocols must ensure the health of everyone in this pandemic and in possible future scenarios. We must transform this crisis into an opportunity that will revolutionize dental education.

RESUMEN: La crisis originada por la COVID-19 ha obligado a desarrollar estrategias para adaptar la enseñanza pre y postgrado en odontología a la nueva situación, así como para garantizar la seguridad de todo el personal de la facultad, estudiantes, pacientes y acompañantes. Revisamos un total de 36 documentos, incluyendo artículos y guías o recomendaciones facilitadas por facultades de odontología, sociedades científicas y otras instituciones, con el fin de obtener la evidencia científica disponible sobre el impacto de la pandemia de la COVID-19 en las facultades de odontología. Las facultades de odontología deben estar preparadas e implementar las medidas necesarias según el nivel de riesgo de infección de SARS-CoV-2 durante las actividades presenciales, especialmente en clínica, además de garantizar una enseñanza de calidad y permitir el desarrollo de investigación. Es fundamental la adaptación de la docencia a las nuevas tecnologías para el desarrollo de formación no presencial, así como la realización de cuestionarios que recaben información sobre la gestión de la crisis y analicen el estrés de estudiantes, profesores y personal. La incorporación de las nuevas tecnologías tanto en la formación como en la evaluación reduce las posibilidades de contagio y potencia la autonomía del alumno. Las competencias de la educación a distancia deben quedar claras para los estudiantes, e incluirse en la descripción del curso académico siendo objetivo primordial de la docencia la adquisición de las mismas. La cooperación internacional de universidades es esencial en la elaboración de protocolos que garanticen la salud de todos en esta pandemia y en posibles futuros escenarios. Esta crisis supone una oportunidad para revolucionar la educación en odontología.

COVID-19 Safety Protocols in Dental Clinical Education in the Second Wave

ABSTRACT: This second wave of the COVID-19 pandemic has led to the development of strategies for guaranteeing clinical teaching in dental schools and adapt it to this new epidemiological situation protecting the health of all staff, stud ents, patients and persons accompanying them. We reviewed a total of 51 documents, including articles and guidelines or recommendations issued by dental schools, scientific societies and other institutions, in order to take stock of the current evidence available about the impact of the COVID-19 pandemic on dental schools. We describe a series of measures to implement in semi-critical and critical areas of dental schools to guarantee the safety of all and the continuity of the clinic al training of students. These include: mobility circuits, appropriate distancing, patient scheduling, telephone triage, personal protective equipments, measures to reduce viral transmission by air ventilation and several other actions specific to low or high aerosol generating by treatments. Dental schools must be prepared and implement the necessary measures according to the level of infection risk during face-to-face activities, especially in clinics, which provide essential formation and imp ossible to acquire online. Dental schools should focus on prioritizing preventive and minimally invasive dentistry minimizing aerosol generating procedures whenever possible. More than ever, the international cooperation among universities for the elaboration of protocols is essential. These protocols must ensure the health of everyone in this new second wave of the pandemic and in possible future epidemiological scenarios.

RESUMEN: Esta segunda oleada de la pandemia COVID-19 ha llevado al desarrollo de estrategias para garantizar la docencia clínica en las facultades de odontología y adaptarla a esta nueva situación epidemiológica protegiendo la salud de todo el personal, estudiantes, pacientes y acompañantes. Revisamos un total de 51 documentos, incluidos artículos y guías o recomendaciones emitidas por escuelas de odontología, sociedades científicas y otras instituciones, con el fin de hacer un balance de la evidencia actual disponible sobre el impacto de la pandemia de COVID-19 en las escuelas de odontología. Describimos una serie de medidas a implementar en áreas semicríticas y críticas de las facultades de odontología para garantizar la seguridad de todos y la continuidad de la formación clínica de los estudiantes. Estos incluyen: circuitos de movilidad, distanciamiento apropiado, programación de pacientes, triaje telefónico, equipos de protección personal, medidas para reducir la transmisión viral por ventilación de aire y varias otras acciones específicas para la generación baja o alta de aerosoles por los tratamientos. Las escuelas de odontología deben estar preparadas e implementar las medidas necesarias de acuerdo al nivel de riesgo de infección durante las actividades presenciales, especialmente en las clínicas, que brindan formación imprescindible e imposible de adquirir en línea. Las escuelas de odontología deben centrarse en priorizar la odontología preventiva y mínimamente invasive minimizando los procedimientos que generan aerosoles siempre que sea posible. Más que nunca, la cooperación internacional entre universidades para la elaboración de protocolos es fundamental. Estos protocolos deben garantizar la salud de todos en esta nueva segunda ola de la pandemia y en posibles escenarios epidemiológicos futuros.

Population pharmacokinetics of vedolizumab in Asian and non-Asian patients with ulcerative colitis and Crohn’s disease

Background/Aims@#Vedolizumab is indicated for moderately-to-severely active ulcerative colitis (UC) and Crohn’s disease (CD). Because multiple factors may result in different pharmacokinetics and clinical efficacies, understanding determinants of vedolizumab clearance may enhance dose and treatment strategies. The aim was to characterize vedolizumab pharmacokinetics in Asian and non-Asian UC and CD patients. @*Methods@#Population pharmacokinetic analysis for repeated measures, using data from 5 studies, was conducted using nonlinear mixed-effects modeling. A Bayesian estimation approach in NONMEM 7.3 was utilized to leverage the predominantly sparse data available for this analysis with results from a prior population pharmacokinetic analysis of vedolizumab. @*Results@#Vedolizumab pharmacokinetics were described by a 2-compartment model with parallel linear and nonlinear elimination. Using reference covariate values, linear elimination half life of vedolizumab was 24.7 days for anti-vedolizumab antibody (AVA)-negative patients and 18.1 days for AVA-positive patients; linear clearance (CLL) was 0.165 L/day for AVA-negative patients and 0.246 L/day for AVA-positive patients; central (Vc) and peripheral compartment volumes of distribution were 3.16 L and 1.84 L, respectively. Interindividual variabilities (percent coefficient of variation) were 30.8% for CLL and 19% for Vc; interoccasion variability on CLL was 20.3%; residual variance was 17.8%. For albumin, body weight and AVA, only extreme values were identified as potentially clinically important predictors of CLL. The effect of race (Asianon-Asian) and diagnosis (UC/CD) on CLL was negligible and likely not of clinical importance. @*Conclusions@#Pharmacokinetic parameters were similar in Asian and non-Asian patients with moderately-to-severely active UC and CD. This analysis supports use of vedolizumab flat-fixed dosing in these patients. (Clinicaltrials.gov Identifiers: NCT00783718 (GEMINI 1); NCT00783692 (GEMINI 2).

Parámetros clínicos, bioquímicos y metabólicos predictores de complicaciones micro y macrovasculares en diabéticos tipo 2 / Clinical, biochemical and metabolic parameters predictive of micro and macrovascular complications in type 2 diabetics / Parâmetros clínicos, bioquímicos e metabólicos preditivos de complicações micro e macrovasculares em diabéticos tipo 2

RESUMEN Introducción: la diabetes mellitus (DM) es una enfermedad endocrino - metabólica, vascular, crónica, producida por una interacción variable de factores genéticos y ambientales. Actualmente la DM2 es considerada por algunos autores como pandémica, sin la existencia de signos de reducción de las tasas de incidencia. Objetivo: identificar los parámetros clínicos, bioquímicos y metabólicos predictores de complicaciones micro y macrovasculares en personas con diabetes mellitus tipo 2. Método: se realizó un estudio analítico de tipo casos y controles con pacientes ingresados en el Centro de Atención al Diabético de Bayamo (CAD), Granma, desde el año 2010 al 2017, 81 con alguna complicación microvascular, 40 con alguna complicación macrovascular y 162 sin ninguna complicación. Resultados: en el análisis univariado se observó que el tiempo de evolución de la enfermedad y la HTA descontrolada fueron los factores de riesgo para el desarrollo de una complicación microvascular, mientras que a estas se le unieron el tabaquismo y le hipercolesterolemia como factores de riesgo para el desarrollo de complicaciones macrovasculares. Las variables que mostraron una relación independiente con el riesgo de desarrollar alguna complicación microvascular fueron el tiempo de evolución de la enfermedad y la HTA descontrolada, mientras que para el desarrollo de complicaciones macrovasculares fueron el tiempo de evolución de la enfermedad y el tabaquismo. Conclusiones: el tiempo de evolución de la diabetes y la HTA descontrolada y el tiempo de evolución de la enfermedad y el tabaquismo se asocian de forma independiente con la aparición de complicaciones microvasculares y macrovasculates respectivamente.

ABSTRACT Introduction: diabetes mellitus (DM) is an endocrine-metabolic, vascular, chronic disease, produced by a variable interaction of genetic and environmental factors. Currently DM2 is considered by some authors as pandemic, without the existence of signs of reduction of incidence rates. Objective: to identify clinical, biochemical and metabolic parameters predictors of micro and macrovascular complications in people with type 2 diabetes mellitus. Method: an analytical case and control study was conducted with patients admitted to the Bayamo Diabetic Care Center (CAD), Granma, from 2010 to 2017, 81 with some microvascular complications, 40 with some macrovascular complications and 162 without any complications. Results: the univariate analysis found that disease progression time and uncontrolled HTA were the risk factors for the development of a microvascular complication, while these were joined by smoking and hypercholesterolemia as risk factors for the development of macrovascular complications. The variables that showed an independent relationship with the risk of developing some microvascular complications were the time of disease evolution and uncontrolled HTA, while for the development of macrovascular complications were the time of disease evolution and smoking. Conclusions: the time of evolution of diabetes and uncontrolled HTA and the time of disease and smoking evolution are independently associated with the emergence of microvascular and macrovasculate complications respectively.

RESUMO Introdução: diabetes mellitus (DM) é uma doença endócrina-metabólica, vascular, crônica, produzida por uma interação variável de fatores genéticos e ambientais. Atualmente o DM2 é considerado por alguns autores como pandemia, sem a existência de sinais de redução das taxas de incidência. Objetivo: identificar preditores de parâmetros clínicos, bioquímicos e metabólicos de complicações micro e macrovasculares em pessoas com diabetes mellitus tipo 2. Método: estudo analítico de caso e controle foi realizado com pacientes internados no Centro de Atendimento Diabético Bayamo (CAD), Granma, de 2010 a 2017, 81 com algumas complicações microvasculares, 40 com algumas complicações macrovasculares e 162 sem complicações. Resultados: a análise univariada constatou que o tempo de progressão da doença e o HTA descontrolado foram os fatores de risco para o desenvolvimento de uma complicação microvascular, enquanto estes foram acompanhados pelo tabagismo e hipercolesterolemia como fatores de risco para o desenvolvimento de complicações macrovasculares. As variáveis que apresentaram relação independente com o risco de desenvolver algumas complicações microvasculares foram o tempo de evolução da doença e HTA descontrolada, enquanto para o desenvolvimento de complicações macrovasculares foi o tempo de evolução da doença e tabagismo. Conclusões: o tempo de evolução do diabetes e do HTA descontrolado e o tempo de evolução da doença e do tabagismo estão independentemente associados ao surgimento de complicações microvasculares e macrovasculadas, respectivamente.
