Association between Periodontitis, Genetic Polymorphisms and Presence of Coronary Artery Disease in Southern Brazil.

BACKGROUND: Periodontitis and coronary artery disease (CAD) share an inflammatory etiology; there is a recent concern regarding the investigation of an association between these two conditions. Current theories indicate that cytokines and proteins have an important role in this process. C-reactive protein and interleukin-6 are inflammatory derivatives produced in the presence of periodontitis and in the pathophysiology of coronary disease. The polymorphisms of CRP + 1444 C > T and IL6-174 G > C are recognized in the literature as being related to CAD. OBJECTIVE: This study investigates the association between periodontitis and coronary artery disease, through the presence of PCR and IL-6 polymorphisms. METHODS: We selected 80 patients who underwent diagnostic catheterization in the HU of UFSM. The presence of periodontitis was determined by the Community Periodontal Index, whereas the CAD was established by the medical report. DNA was collected from a saliva sample and the presence of polymorphism was determined by PCR and restriction enzymes. A significance level of 5% was adopted. RESULTS: The mean age of all participants (p = 0.035, OR 2.65; 95%CI: (1.02-6.87) male gender (p = 0.012, OR 3.37; 95% CI: (1.28- (p = 0.013, OR 3.66; 95% CI: (1.27-10.5)), PCR polymorphism + 1444C > T (p = 0.001, OR 6.37; 95% CI:, (2.25-17.9)) and IL6 -174 G > C polymorphism (p = 0.025, OR 2.87, 95% CI: (1.09-7.55)) were statistically associated with the presence of CAD. Age > 60 years and presence of the PCR +1444 C > T polymorphism remained independently associated with CAD after adjustment by logistic regression. CONCLUSIONS: The presence of the PCR + 1444 C > T polymorphism in this study was independently associated with the presence of coronary artery disease.

Resumo Fundamento: A periodontite e a doença arterial coronariana (DAC) compartilham uma etiologia inflamatória. Existe preocupação na investigação de associação entre essas duas condições. Há citocinas e proteínas com papel importante neste processo, como a proteína C-reativa (PCR) e a interleucina 6 (IL-6), que são derivados inflamatórios produzidos na presença da periodontite e na fisiopatologia da DAC. Os polimorfismos da PCR+1444 C > T e da IL-6 -174 G > C são reconhecidos na literatura como relacionados à DAC. Objetivo: Este estudo objetiva comprovar a associação entre periodontite e DAC, através da presença dos polimorfismos da PCR e da IL-6. Métodos: Foram selecionados 80 pacientes que se submeteram ao cateterismo diagnóstico no Hospital Universitário da Universidade Federal de Santa Maria (UFSM). A periodontite foi determinada pelo índice periodontal comunitário; a DAC, pelo laudo médico. Foi coletado o ácido desoxirribonucleico (DNA) pela saliva e estabelecido o polimorfismo pela avaliação da PCR/RFLP. Foi adotado um nível de significância estatística de 5%. Resultados: A idade mediana de todos os participantes (p = 0,035; OR 2,65; IC 95% [1,02-6,87]), gênero masculino (p = 0,012; OR 3,37; IC 95% [1,28-8,9]), periodontite (p = 0,013; OR 3,66; IC 95% [1,27-10,5]), polimorfismo da PCR +1444 C > T (p = 0,001; OR 6,37; IC 95% [2,25-17,9]) e polimorfismo da IL-6 -174G > C (p = 0,025; OR 2,87; IC 95% [1,09-7,55]) foram estatisticamente relacionados à DAC. Após ajuste com a regressão logística, mantiveram-se independentemente associadas à DAC a idade maior que 60 anos e o polimorfismo da PCR +1444 C > T. Conclusões: O polimorfismo da PCR +1444 C > T, neste estudo, esteve independentemente relacionado à DAC.

Atualização na reanimação volêmica no paciente traumatizado / Update on volemic resuscitation in trauma patient

Introdução: O choque hipovolêmico é o principal tipo de choque no trauma. Seu manejo é fundamental visto que é uma das principais causas de mortes evitáveis. Objetivos: Definir conceitos relacionados à reanimação no choque hipovolêmico, como coagulopatia precoce no trauma, controle de danos, hipotensão permissiva, uso de cristaloides e hemoderivados, ácido tranexâmico e protocolo de transfusão maciça. Metodologia: Busca na base de dados bibliográfica Medline/Pubmed e LILACS no período de maio de 2018, incluindo artigos de revisão, revisões sistemáticas e guidelines cuja publicação seja em inglês ou português e remeta os últimos 5 anos. Os descritores foram "permissive hypotension" ou "damage control resuscitation". "hypovolemic shock". Os artigos foram selecionados com busca direta, considerando relevância do tema à proposta e revista com fator de impacto mensurado. Resultados: Foram apresentados 342 resultados da busca de dados, nos quais 15 artigos foram selecionados. Na conduta do choque hipovolêmico, responsável por 30 a 40% das mortes no período de 24 horas após o trauma, adota-se a hipotensão permissiva e preconiza-se o controle de danos. Conclusões: O entendimento da coagulopatia no trauma, do uso limitado de cristaloides, da reanimação balanceada, da hipotensão permissiva, da correta indicação do ácido tranexâmico e da aplicação do protocolo de transfusão maciça é fundamental na reanimação volêmica do paciente traumatizado.

Introduction: The hypovolemic shock is the main type of shock in trauma patients. Its management is fundamental given that hemorrhagic shock is one of the main causes of death that can be avoided. Aims: To define concepts related to resuscitation in hypovolemic shock, such as early coagulopathy in trauma, damage control, permissive hypotension, use of crystalloids and blood derivatives, tranexamic acid and massive transfusion protocol. Methods: Search in the bibliographic database Medline/Pubmed and LILACS in the period of May 2018, including review articles, systematic reviews and guidelines published in either English or Portuguese in the last 5 years. The descriptors were "permissive hypotension" or "damage control resuscitation". Of the 342 results, 15 articles were selected with direct search, considering relevance of the theme to the proposal and reviewed with measured impact factor. Results: From 342 results in database, 10 articles have been selected. The management of hypovolemic shock, responsible for 30-40% of deaths within 24 hours of trauma, permissive hypotension and damage control have been recommended. Conclusion: The understanding of coagulopathy in trauma, of limited use of crystalloids, of balanced resuscitation, of permissive hypotension, of the correct indication of tranexamic acid and of the application of the protocol of massive transfusion is essential in the resuscitation of the trauma patient.

Síndrome pré-menstrual e síndrome disfórica pré-menstrual: aspectos atuais / Premenstrual syndrome and premenstrual dysphoric syndrome: current aspects

A síndrome pré-menstrual (SPM) caracteriza-se por um conjunto de sintomas físicos, emocionais e comportamentais, cíclicos e recorrentes que iniciam na semana anterior à menstruação e aliviam com o início do fluxo, sendo um distúrbio altamente prevalente entre as mulheres em idade fértil. Enquetes epidemiológicas mostram que 75 a 80% das mulheres apresentam sintomas durante o período pré-menstrual. A revisão de literatura, entretanto, mostrou que o assunto está longe de um consenso, com controvérsias sobre fatores de risco, proteção e tratamento. Uma vez confirmado o diagnóstico, modificações no estilo de vida, suplemento de cálcio, vitamina B12 e V. agnus castus são opções não-farmacológicas razoáveis. Os inibidores seletivos de recaptação da serotonina (ISRS) são atualmente considerados a classe farmacológica mais efetiva. Outra opção é o uso de anticoncepcionais orais (ACO) combinados com etinilestradiol (EE) e drospirenona que foram aprovados pela Food and Drug Administration (FDA) para o tratamento da SPM e do transtorno disfórico pré-menstrual (TDPM)

The premenstrual syndrome (PMS) is characterized by a set of physical symptoms, emotional and behavioral, cyclical and recurring that start in the week before menstruation and relieve the beginning of the stream, being a highly prevalent disorder among women of childbearing age. Epidemiological surveys show that 75 to 80% of women experience symptoms during the premenstrual period. The literature review, however, showed that the subject is far from a consensus, with controversies about risk factors, protection and treatment. Once the diagnosis is confirmed, changes in lifestyle, calcium supplement, vitamin B12 and V. agnus castus are pharmacologic reasonable options. The selective serotonin reuptake inhibitors (SSRIs) are currently considered the most effective pharmacological class. Another option is the use of oral contraceptive combined with drospirenone and ethinilestradiol (EE) which were approved by the Food and Drug Administration (FDA) for the treatment of PMS and premenstrual dysphoric disorder (PMDD)
