RESUMO
This review focuses on three major aspects of oncoviruses' role in cancer development. To begin, we discuss their geographic distribution, revealing that seven oncoviruses cause 20% of all human cancers worldwide. Second, we investigate the primary carcinogenic mechanisms, looking at how these oncogenic viruses can induce cellular transformation, angiogenesis, and local and systemic inflammation. Finally, we investigate the possibility of SARS-CoV-2 infection reactivating latent oncoviruses, which could increase the risk of further disease. The development of oncovirus vaccines holds great promise for reducing cancer burden. Many unanswered questions about the host and environmental cofactors that contribute to cancer development and prevention remain, which ongoing research is attempting to address.
RESUMO
BACKGROUND: This study determined the prevalence of aggressive (molar-incisor pattern) (Ag/MI) periodontitis and assessed the associated subgingival bacterial-herpesvirus microbiota in Pueblo Indian adolescents in the southwestern United States. METHODS: The study included 240 Pueblo Indian adolescents, aged 13-20 years old, residing in three Rio Grande River villages in New Mexico and the Hopi Pueblo reservation in Arizona. Adolescents with Ag/MI periodontitis or periodontal health provided subgingival samples for culture of bacterial pathogens and for polymerase chain reaction detection of periodontal herpesviruses. RESULTS: Ag/MI periodontitis was detected in 22 (9.2%) Pueblo Indian adolescents, with 21 exhibiting a localized molar-incisor breakdown pattern. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and other red/orange complex bacterial pathogens predominated in Ag/MI periodontitis, whereas periodontal health yielded mainly viridans streptococci and Actinomyces species. Periodontal herpesviruses demonstrated a 3.5 odds ratio relationship with Ag/MI periodontitis. The only adolescent with generalized Ag/MI periodontitis harbored viral co-infection by cytomegalovirus plus Epstein-Barr virus Type 1, in addition to A. actinomycetemcomitans, P. gingivalis, and several other periodontopathic bacteria. CONCLUSIONS: Pueblo Indian adolescents showed an unusually high prevalence of early-age Ag/MI periodontitis predominated by periodontopathic bacteria and herpesviruses suspected to be major etiologic agents of the disease.
RESUMO
Periodontitis has significant public health implications, affecting individuals' overall health, well-being, and quality of life. This study aimed to assess the risk factors associated with the extent of clinical attachment loss (CAL) in a population diagnosed with periodontitis. Six hundred and sixty-seven patients with different degrees of CAL (mild, n = 223; moderate, n = 256; and advanced, n = 188) were enrolled. Socio-demographics, lifestyle, microbiological profiles, specific immune response, obesity, and single-nucleotide polymorphism of the IL1 gene were determined. Unconditional logistic regression models were conducted to determine the factors associated with the extent of CAL. Aging, smoking, microbial factors, plaque index, and IgG2 antibodies against Aggregatibacter actinomycetemcomitans were associated with advanced CAL. IgG2 antibodies against A. actinomycetemcomitans (OR 1.50; CI 95% 1.23-1.81), plaque accumulation (OR 2.69; CI 95% 2.20-3.29), Porphyromonas gingivalis (OR 1.93; CI 95% 1.35-2.76), Tanerella forsythia (OR 1.88; CI 95%1.30-2.70), and current smoking (OR 1.94; CI 95% 1.31-2.87) were associated with advanced CAL. Gene IL polymorphisms, obesity, and stress were not associated with the extent of CAL. Aging, plaque accumulation, smoking, and having antibodies against A. actinomycetemcomitans were the most critical factors associated with advanced CAL. In contrast, obesity, stress, and gene polymorphisms were not associated with the extent of CAL.

Introducción: El consumo de bebidas azucaradas y alimentos no saludables es un problema de Salud Pública y de las Políticas Públicas que buscan reducir el impacto de las Enfermedades No Trasmisibles (ENT) en América Latina. Objetivo: identificar las Políticas Públicas generadas en Colombia, Argentina y Chile para la regulación del consumo de azúcar y comida chatarra. Materiales y Métodos: Análisis exploratorio a través de una revisión de literatura y revisión de documentos normativos. Resultados: Colombia en el año 2021 sancionó la Ley 2120 denominada "Ley de Comida Chatarra", que promueve el acceso a información necesaria para fomentar entornos alimentarios saludables y prevenir las ENT, que incluye nuevas normas para el etiquetado de alimentos y describir sus características al consumidor y así limitar el consumo de alimentos procesados y ultraprocesados. Chile fue pionero en el desarrollo de los sellos de advertencia y desde el año 2014, aplica un impuesto adicional a las bebidas no alcohólicas. Argentina en 2021, sancionó la ley que obliga a la industria de alimentos a disponer de etiquetas en los envases que alerten al consumidor sobre los excesos de azúcares, grasas y sodio Conclusiones: Los tres países investigados cuentan con políticas de etiquetado de alimentos procesados, y en Chile existen impuestos a las bebidas azucaradas. Es importante estudiar el impacto de dichas políticas en la prevalencia y severidad de las ENT y de la caries.
Abstract: The consumption of sugar-sweetened beverages and unhealthy foods is a public health problem that has become a regulatory issue for the public policies aimed at reducing the impact of Non Communicable Diseases (NCDs) in Latin America. Objective: to identify the Public Policies in Colombia, Argentina and Chile for the regulation of the consumption of sugar and junk food. Materials and methods. Exploratory analysis through a literature and policy documents review. Results: In 2021, Colombia approved the Law 2120 called "Junk Food Law" promoting public access to information for a healthy food environment to prevent NCDs. It includes food labeling for overweight and obesity prevention and establishes a specific labeling regulation for processed and ultra-processed food and sweet drink products. Chile was pioneer in the development of warning stamps on food packages and since 2014 also taxes sweet non-alcoholic beverages. In 2021, Argentina approved a law to add labels on food packages to alert consumers about excess of sugars, fats and sodium. Conclusions: The three investigated countries have labeling policies for processed food, and Chile puts taxes on sugary drinks. It is important to study the impact of these policies on NCD prevalence, severity and on dental caries.

This case series included a tomographic, microbiological, and histopathological description of 15 secondary apical periodontitis (SAP) lesions obtained by apical microsurgery performed in 10 patients to better understand the etiology and pathogenesis of SAP. Preoperative tomographic analyses were performed through Cone beam computerized tomography - Periapical index (CBCT-PAI), and apical microsurgeries were then carried out. The removed apices were used for microbial culturing and for molecular identification using PCR for the detection of 5 strict anaerobic bacteria (P. gingivalis, P. intermedia, P. nigrescens, T. forsythia, and T.denticola) and 3 viruses Herpes simplex viruses (HSV), Cytomegalovirus (CMG) and Epstein-Barr Virus (EBV) by nested PCR. The removed apical lesions were histologically described. Univariate statistical analyses were performed by using STATA MP/16 (StataCorp LLC, College Station, TX, United States). CBCT-PAI analyses revealed PAI 4 and PAI 5 score lesions that involved cortical plate destruction. Eight SAPs were positive by culture, while nine SAP lesions were positive by PCR. Fusobacterium species were the most frequently cultured organisms in 7 SAP lesions, followed by D. pneumosintes in 3. In contrast, by single PCR, T. forsythia and P. nigrescens were detected in 5 lesions, T. denticola in 4 lesions, and P. gingivalis in 2 lesions. Twelve periapical lesions were granulomas, and the remaining three SAP lesions were radicular cysts. In conclusion, this case series study revealed that secondary apical lesions presented tomographic involvement of PAI 3 to 5, and that most SAP lesions were apical granulomas containing anaerobic and facultative microorganisms.

Resumo Esta série de casos incluiu uma descrição tomográfica, microbiológica e histopatológica de 15 lesões de periodontite apical secundária (SAP) obtidas por microcirurgia apical realizada em 10 pacientes para melhor compreender a etiologia e patogénese do SAP. As análises tomográficas pré-operatórias foram realizadas através de tomografia computadorizada de feixe cônico - índice Periapical (CBCT-PAI), e as microcirurgias apicais foram então realizadas. Os ápices removidos foram utilizados para a cultura microbiana e também para a identificação molecular por PCR para a detecção de 5 bactérias anaeróbias rigorosas (P. gingivalis, P. intermedia, P. nigrescens, T. forsythia, e T.denticola) e 3 vírus Herpes simplex (HSV), Cytomegalovirus (CMG) e Epstein-Barr Virus (EBV) por PCR aninhada. As lesões apicais removidas foram descritas histologicamente. Foram realizadas análises estatísticas univariadas utilizando STATA MP/16 (StataCorp LLC, College Station, TX, Estados Unidos da América). As análises CBCT-PAI revelaram lesões PAI 4 e PAI 5 que envolveram a destruição da placa cortical. Oito SAPs foram positivos por cultura, enquanto nove lesões de SAP foram positivas por PCR. As espécies de Fusobacterium foram os organismos mais frequentemente cultivados em 7 lesões SAP, seguidas por D. pneumosintes em 3. Em contraste, por PCR simples, T. forsythia e P. nigrescens foram detectados em 5 lesões, T. denticola em 4 lesões, e P. gingivalis em 2 lesões. Doze lesões periapicais foram granulomas, e as restantes três lesões SAP foram cistos. Em conclusão, este estudo de série de casos revelou que as lesões apicais secundárias apresentavam envolvimento tomográfico de PAI 3 a 5, e que a maioria das lesões de SAP eram granulomas apicais contendo microrganismos anaeróbios e facultativos.
RESUMO
Previous studies have suggested that graphene oxide (GO) has some antiviral capacity against some enveloped viruses, including SARS-CoV-2. Given this background, we wanted to test the in vitro antiviral ability to GO using the viral plaque assay technique. Two-dimensional graphene oxide (GO) nanoparticles were synthesized using the modified Hummers method, varying the oxidation conditions to achieve nanoparticles between 390 and 718 nm. The antiviral activity of GO was evaluated by experimental infection and plaque formation units assay of the SARS-CoV-2 virus in VERO cells using a titrated viral clinical isolate. It was found that GO at concentrations of 400 µg/mL, 100 µg/mL, 40 µg/mL, and 4 µg/mL was not toxic to cell culture and also did not inhibit the infection of VERO cells by SARS-CoV-2. However, it was evident that GO generated a novel virus entrapment phenomenon directly proportional to its concentration in the suspension. Similarly, this effect of GO was maintained in assays performed with the Zika virus. A new application for GO nanoparticles is proposed as part of a system to trap viruses in surgical mask filters, air conditioning equipment filters, and air purifier filters, complemented with the use of viricidal agents that can destroy the trapped viruses, an application of broad interest for human beings.
RESUMO
Durante dos años y medio, tanto en Colombia como en el resto del mundo, hemos enfrentado la pandemia generada por el SARS-CoV-2, agudizando los múltiples problemas de salud pública que venían cursando a manera de sindemias. Tal es el caso de las enfermedades crónicas no transmisibles asociadas, entre otros factores, a los malos hábitos alimenticios, especialmente por el gran consumo de alimentos ultraprocesados y bebidas azucaradas. En julio del 2021, se aprobó la Ley 2120, por medio de la cual se adoptaron medidas para fomentar entornos alimentarios saludables. Entre estas medidas, también se promueve que los alimentos empacados, procesados y que afectan negativamente la salud humana, tengan un sello que identifique sus componentes y valor nutricional para informar a los consumidores sobre el producto que están comprando o consumiendo. Entre las enfermedades más prevalentes en Colombia que afectan la salud bucal, se encuentran las caries y las periodontitis, ambas con factores de riesgo comunes con las enfermedades crónicas no transmisibles. Dados sus costos y prevalencia, dichas enfermedades crónicas no transmisibles resultan primordiales desde un enfoque de gestión del riesgo en salud pública, siendo, quizá, su gravedad mayor durante la pandemia generada por el SARS CoV-2. Asimismo, se especula que la población confinada pudo llegar a consumir más comida chatarra durante la pandemia del COVID-19 en comparación con otros períodos, además, porque en aquellos con enfermedades crónicas no transmisibles, el confinamiento obligado se asocia con mayor sedentarismo y con un menor número de controles médicos regulares, asuntos que se han reportado previamente. La promulgación de la ley de comida chatarra no va a cambiar los hábitos de alimentación de los colombianos "de la noche a la mañana" y, por esto, se necesita con urgencia implementar procesos de educación y sensibilización frente a los efectos adversos de los alimentos procesados y ultraprocesados en la salud.

For more than one year and a half, Colombia and the world have been facing the effects caused by the pandemics of SARS CoV-2 with concomitant and aggravating deterioration of multiple public health problems such as noncommunicable diseases. Noncommunicable diseases are frequently associated with poor eating habits and regular consumption of processed and ultra-processed foods, among other important risk factors related to culture, genetics, and sedentarism. In July, 2021, Colombia ratified the Law 2120 that promotes healthy food habits and recreational environments, by forcing food producers to include nutritional advertisement seals on processed food packages, with explanatory guidelines for consumers about calories and nutritional value. This editorial note highlights the importance in Odontology of promoting and implementing this Law through education and sensitization of populations, in order to cope with some of the adverse risk factors of the hypercaloric diet.

OBJECTIVE: Describes dental, occlusal, and craniofacial characteristics of 3 children aged 3 to 4 years with microcephaly due to congenital Zika infection in Cali Valle del Cauca, 2020. DESIGN: Three children case report with congenital Zika virus microcephaly. SETTING: Institutional. PATIENTS: Three children with maternal viral infection confirmed by polymerase chain reaction during first trimester of pregnancy were included and were born from 2016 to 2017. INTERVENTIONS: Oral and mouth functional examination was performed including soft tissue examination; lingual and labial frenulum; evaluation of swallowing and chewing; craniofacial analysis; dimension of dental arch; intercanine and intermolar distance, palate form; relationship and growth of maxilla, mandible, and facial dental midline using plaster models; and complementary image analysis. MAIN OUTCOME MEASURES: Child and mother sociodemographic features, craniofacial measurements; dental and oral features; maxillary and mandibular measures; and speech, swallowing, and chewing disorders. RESULTS: Small head circumference at birth and at the time of clinical evaluation was compared to normal children of approximately their age. Upper third of the face was short, and presence of hypertonic masticatory muscles with hypotonic swallowing muscles, dysphagia, dyslalia, bruxism, lip incompetence, tongue interposition, and hypersalivation and epilepsy were the main medical problem. They have complete primary dentition with normal dental morphology, tooth eruption altered, dental caries, and dental malocclusion was identified. CONCLUSION: There are no changes in the dental formula and dental morphology in the deciduous dentition. They present severe chewing and speaking limitation, facial disproportion, and occlusal problems that warrant dental and medical attention.

BACKGROUND AND OBJECTIVE: Human cytomegalovirus (HCMV) has been associated with periodontitis and apical periodontitis. The objective of this systematic review was to evaluate the association between HCMV and periodontitis, and apical periodontitis of endodontic origin. MATERIAL AND METHODS: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines and registered in the International prospective register of systematic reviews (PROSPERO). The search for potential studies was performed in MEDLINE via PubMed, Scopus, and SciELO. A quality assessment of the studies, publication bias analysis, and meta-analysis was performed. The results are presented in odds ratio with 95% confidence interval with the corresponding Forest plot. Sensitivity analysis was performed to evaluate the consistency of the results. RESULTS: Thirty-two studies were included in the quantitative and qualitative analyses. Of these, 26 were in periodontitis patients and 6 in apical periodontitis patients. Forest plot of combined studies revealed significant increased odds for periodontitis when subgingival HCMV was detected (OR 5.31; 95% CI 3.15-8.97). Sensitivity analysis based on quality of the included studies, showed consistent results. In contrast, the odds ratio for apical periodontitis when HCMV was detected from apical lesions was not statistically significant (OR 3.65; 95% CI 0.49-27.10). CONCLUSIONS: The results from the meta-analysis indicate that HCMV is significantly associated with periodontitis. In contrast, HCMV infection is not associated with apical periodontitis.

Periodontitis pathogenesis involves activation of host immune responses triggered by microbial dysbiosis. Therefore, controlling periodontal pathogens in-vivo is a main goal of periodontal therapy. New antimicrobials might help to control periodontal infection and improve treatment outcomes at "the dark times" of increasing antibiotic resistance. Here, we determined the biological activity of collinin and isocollinin against 8 bacterial strains. Antimicrobial activity of collinin and isocollinin, chlorhexidine digluconate (CHX) and sodium hypochlorite (NaClO) was evaluated against clinically relevant periodontal bacteria, like Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum, Prevotella intermedia, Dialister pneumosintes strains and superinfectants like Escherichia coli, Staphylococcusaureus, and Pseudomonasaeruginosa strains. A broth microdilution test was carried out to determine the minimum inhibitory concentration of collinin and isocollinin against those strains, and bacterial viability was determined by resazurin assay at diverse concentration and exposure times. P. gingivalis was the most susceptible strain to collinin and isocollinin (MIC 2.1 µg/mL and 4.2 µg/mL respectively). Other periodontal pathogens showed MICs <17 µg/mL for collinin and MICs between 20 and 42 µg/mL for isocollinin, whereas CHX and NaClO showed MICs of 62 and 326 µg/mL, respectively. Collinin and isocollinin also exhibited antimicrobial activity against superinfectant bacteria (MIC < 21 and < 42 µg/mL, respectively). Overall, collinin and isocollinin showed a remarkable antibacterial activity against relevant periodontal and superinfective bacteria, especially against P. gingivalis (MIC 2.1 µg/mL and 4.2 µg/mL respectively) and the highly virulent P. aeruginosa (MIC 5.2 and 20.8 µg/mL, respectively).

Hace cincuenta años el 4 de junio de 1970, fue creado el Departamento de Estomatología adscrito a la División de Salud, el cual dio origen en 1990 a la Escuela de Odontología, que estará celebrando medio siglo de creación y desarrollo, en el 2020 (1). Inicialmente, el 27 de Febrero de 1957 se había nombrado un comité para estudiar la creación de la Facultad de Odontología en la Universidad del Valle. Dicho comité incluyó, entre otros, a los médicos Luis María Borrero y Pablo Barreto Reyes, y a los odontólogos Itamar Alcalay, Gustavo Ulloa Iragorry y Jaime Ángel. Sin embargo, aunque la propuesta presentada en el Primer Plan Quinquenal de Desarrollo de la Facultad de Medicina auspiciada por las Fundaciones Rockefeller y Kellogg permitió el fortalecimiento y expansión de los Departamentos de Ciencias Básicas Médicas de la Facultad, este no contó con la aprobación para crear un programa de odontología, debido al alto costo de la propuesta, asociado a la dotación de infraestructura y equipos para los laboratorios, preclínicas y clínicas (2). Este articulo pretende recopilar los mas relevantes hitos de un largo camino que se inicio oficialmente con la creación en 1965 del Comité Universitario Pro Facultad de Odontología CUPFO, integrado por los odontólogos José Fernando Barreto y Jaime Álvarez entre otros. Dicho comité impulsó la creación del Departamento de Estomatología, el de Junio de1970. Para entonces un selecto grupo de profesionales de la Odontología de Cali liderados por el doctor José Fernando Barreto le propusieron a la Organización Panamericana de la Salud-OPS y a los Ministerios de Salud y de Educación la creación de dos programas revolucionarios para la época, un pregrado en Odontología de cuatro años de duración, el cual al ser finalizado daba la posibilidad de continuar con estudios de Magister en Estomatología con dos años adicionales de estudio; el servicio social obligatorio contaría como uno de los años de la Maestría. Ambos programas de estudios estaban apoyados por trabajos previos en donde, se destacan los programas de auxiliares de Odontología, cuyo espectro contemplaba desde los niveles mas básicos del personal de apoyo a los servicios de odontología representadas en las auxiliares de consultorio, niveles intermedios de complejidad como el programa de auxiliares de higiene oral o higienista, y un programa novedoso para Colombia y América Latina como eran los auxiliares de Odontología social que tenia funciones de operatorista y que trabajarían con la supervisión del odontólogo y/o estomatólogo, y cuya función era incrementar el acceso al cuidado de la salud bucal, una necesidad real de los Colombianos para esa época. La auxiliar de Odontología Social, se derivaba del programa o enfermera dental en Nueva Zelanda (1). Los principales principios del nuevo profesional de la Odontología eran: 1. Tener un fuerte conocimiento y uso de las ciencias básicas biomédicas para fortalecer su trabajo clínico; 2. Poseer la capacidad de implementar y supervisar programas de estomatología social y/o comunitaria en los puestos, centros de salud y hospitales de la red publica, a nivel departamental, con enfoque de atención primaria de la salud y en donde lo primordial es intervenir los riesgos en salud del grupo familiar, con el apoyo de las auxiliares de Odontología, 3. Fortalecer la promoción de la salud, el uso de los equipos de odontología simplificado y el trabajo a cuatro manos con auxiliares de consultorio, auxiliares de higiene oral, y auxiliares de odontología social para masificar la promoción de la salud y la atención en salud entre la población, 4. Consolidar al estomatólogo (médico de la boca), como el líder de la pirámide del equipo de salud bucal con fortalezas en el diagnostico, prevención y tratamiento de las principales patologías bucales y su relación son la salud general, con capacidad resolutiva y las competencias para la dirección y coordinación de los equipos de salud para trabajar en el ámbito gubernamental, en los puestos de salud y centros hospitales del Departamento del Valle y en el área de influencia del sur-occidente Colombiano (1,2).
RESUMO
INTRODUCTION: In 2016, the World Health Organization reported that more than 2 billion adults were overweight, of whom 600 million were obese, 347 million had diabetes mellitus type II, and people with hypertension had increased from 600 million in 1980 to 1 billion in 2010. Additionally, 20% of the world's adult population will develop metabolic syndrome during their lifespan with tremendous effects for their wellbeing and the health systems. OBJECTIVE: To identify social, biological, and behavioral factors associated with the metabolic syndrome in adults to help in the design of health policies in urban environments. MATERIALS AND METHODS: We included 300 cases and 675 controls. For cases, the waist circumference (abdominal obesity) in men was ≥94 cm and ≥88 cm in women, and other two factors should be present including hypertension, high glycated hemoglobin, high triglycerides, and low HDL levels. Controls presented only one or none of these risk factors. RESULTS: The total prevalence of metabolic syndrome was 30.2%, 33.6% in females, and 25.6% in males. Therefore, females had a higher risk of developing a metabolic syndrome (OR=1.70; 95% CI 1.17-2.47). Being a mestizo also increased the risk of having metabolic syndrome (OR=1.55; 95% CI 1.10-2.19). In contrast, frequent fruit consumption and being a housekeeper were protective factors: OR=0.83; 95% CI 0.69-1.00, and OR=0.58; 95% CI 0.36-0.92, respectively. Logistic regression showed that obesity had the strongest association with metabolic syndrome (OR=7.52; 95% CI 4.79-11.80). Increasing age yielded a linear trend with regard to metabolic syndrome: the OR for the 40 to 49-year-old group was 4.24 (95% CI 2.20-8.16), for the 50 to 59-year-old group, 4.63 (95% CI 2.40-8.93), and for those over 80 years of age, 5.32 (95% CI 1.92-14.71). CONCLUSION: Obesity was the main risk factor associated with the metabolic syndrome. Our findings can help health policy makers to design interventions for metabolic syndrome control in urban populations in Colombia.
Introducción. En el 2016, la Organización Mundial de la Salud reportó la existencia de casi 2000 millones de adultos con sobrepeso, de los cuales más de 600 millones presentaban obesidad, 347 millones tenían diabetes mellitus de tipo 2, y las personas con hipertensión habían aumentado de 600 millones en 1980 a mil millones en el 2010. Además, 20 % de los adultos desarrollaría el síndrome metabólico con los consecuentes efectos negativos en sus vidas y en los servicios de salud. Objetivo. Determinar los factores de riesgo en la esfera social, biológica y de comportamiento asociados con el síndrome metabólico. Materiales y métodos: Se seleccionaron 300 casos y 675 controles. Los casos se definieron como los hombres con una circunferencia de cintura (obesidad abdominal) de ≥94 cm y las mujeres con ≥88 cm y que presentaran, además, otros dos factores entre los siguientes: hipertensión arterial sistémica, hemoglobina 'glicosilada' alta, triglicéridos altos y bajos niveles de colesterol de baja densidad. Los controles eran personas que no presentaban ninguno de los factores de riesgo o solo uno de ellos. Resultados. La prevalencia del síndrome metabólico fue de 30,2 %: 33,6 % en mujeres y 25,6 % en hombres. Las mujeres presentaron un mayor riesgo, con una odds ratio (OR) de 1,70 (IC95% 1,17-2,47), seguidas por los mestizos con una OR de 1,55 (1,10-2,19). El consumo regular de frutas y el ser ama de casa fueron factores protectores, con una OR de 0,83 (IC95% 0,69-1,00) y de 0,58 (IC95% 0,36-0,92), respectivamente. La obesidad fue el factor de riesgo con la mayor asociación (OR=7,52; IC95% 4,79-11,80). El síndrome metabólico aumentó con la edad, así, las personas entre 40 y 49 años presentaron una OR de 4,24 (IC95% 2,20-8,16), la de 50 a 59 años, una de 4,63 (IC95% 2,40-8,93) y los mayores de 80 años, una de 5,32 (IC95% 1,92-14,71). Conclusiones. Estos hallazgos pueden facilitar la implementación de medidas de intervención para el control del síndrome metabólico.

Abstract Introduction: In 2016, the World Health Organization reported that more than 2 billion adults were overweight, of whom 600 million were obese, 347 million had diabetes mellitus type II, and people with hypertension had increased from 600 million in 1980 to 1 billion in 2010. Additionally, 20% of the world's adult population will develop metabolic syndrome during their lifespan with tremendous effects for their wellbeing and the health systems. Objective: To identify social, biological, and behavioral factors associated with the metabolic syndrome in adults to help in the design of health policies in urban environments. Materials and methods: We included 300 cases and 675 controls. For cases, the waist circumference (abdominal obesity) in men was ≥94 cm and ≥88 cm in women, and other two factors should be present including hypertension, high glycated hemoglobin, high triglycerides, and low HDL levels. Controls presented only one or none of these risk factors. Results: The total prevalence of metabolic syndrome was 30.2%, 33.6% in females, and 25.6% in males. Therefore, females had a higher risk of developing a metabolic syndrome (OR=1.70; 95% CI 1.17-2.47). Being a mestizo also increased the risk of having metabolic syndrome (OR=1.55; 95% CI 1.10-2.19). In contrast, frequent fruit consumption and being a housekeeper were protective factors: OR=0.83; 95% CI 0.69-1.00, and OR=0.58; 95% CI 0.36-0.92, respectively. Logistic regression showed that obesity had the strongest association with metabolic syndrome (OR=7.52; 95% CI 4.79-11.80). Increasing age yielded a linear trend with regard to metabolic syndrome: the OR for the 40 to 49-year-old group was 4.24 (95% CI 2.20-8.16), for the 50 to 59-year-old group, 4.63 (95% CI 2.40-8.93), and for those over 80 years of age, 5.32 (95% CI 1.92-14.71). Conclusion: Obesity was the main risk factor associated with the metabolic syndrome. Our findings can help health policy makers to design interventions for metabolic syndrome control in urban populations in Colombia.
Resumen Introducción. En el 2016, la Organización Mundial de la Salud reportó la existencia de casi 2000 millones de adultos con sobrepeso, de los cuales más de 600 millones presentaban obesidad, 347 millones tenían diabetes mellitus de tipo 2, y las personas con hipertensión habían aumentado de 600 millones en 1980 a mil millones en el 2010. Además, 20 % de los adultos desarrollaría el síndrome metabólico con los consecuentes efectos negativos en sus vidas y en los servicios de salud. Objetivo. Determinar los factores de riesgo en la esfera social, biológica y de comportamiento asociados con el síndrome metabólico. Materiales y métodos. Se seleccionaron 300 casos y 675 controles. Los casos se definieron como los hombres con una circunferencia de cintura (obesidad abdominal) de ≥94 cm y las mujeres con ≥88 cm y que presentaran, además, otros dos factores entre los siguientes: hipertensión arterial sistémica, hemoglobina 'glicosilada' alta, triglicéridos altos y bajos niveles de colesterol de baja densidad. Los controles eran personas que no presentaban ninguno de los factores de riesgo o solo uno de ellos. Resultados. La prevalencia del síndrome metabólico fue de 30,2 %: 33,6 % en mujeres y 25,6 % en hombres. Las mujeres presentaron un mayor riesgo, con una odds ratio (OR) de 1,70 (IC95% 1,17-2,47), seguidas por los mestizos con una OR de 1,55 (1,10-2,19).El consumo regular de frutas y el ser ama de casa fueron factores protectores, con una OR de 0,83 (IC95% 0,69-1,00) y de 0,58 (IC95% 0,36-0,92), respectivamente.

RESUMEN Introducción: La enfermedad periodontal (EP) y la artritis reumatoide (AR) son enfermedades inflamatorias crónicas multifactoriales que tienen en común algunos factores etiopatogénicos y la destrucción de los tejidos dentoalveolares y de las articulaciones sinoviales, de tal forma que se han identificado anticuerpos contra microorganismos periodontales en el fluido crevicular, líquido sinovial y en la membrana sinovial. Objetivo: Identificar, recuperar, analizar críticamente y sintetizar la literatura disponible acerca de la prevalencia de microorganismos periodontales en el líquido sinovial de pacientes con AR. Materiales y métodos: Se realizó búsqueda sistemática en Medline, ScienceDirect, SciELO y Google Scholar a través de los descriptores en salud Rheumatoid arthritis, periodontal microorganisms y synovial fluid. Se incluyeron artículos que describieron la presencia de microorganismos periodontales aislados en líquido sinovial de pacientes diagnosticados con AR. La búsqueda se cerró en febrero de 2017 y fue realizada con metodología PRISMA. Se emplearon las fichas de lectura crítica OSTEBA para valorar la validez externa y el nivel de evidencia de cada artículo en función del rigor metodológico. Resultados: Catorce publicaciones describieron la presencia de microorganismos periodontales en líquido sinovial de pacientes con EP y AR. Seis publicaciones realizaron detección de microorganismos periodontales en muestras de líquido sinovial, identificando en todas a P. gingivalis. Conclusiones: Los estudios incluidos evidenciaron la presencia de microrganismos periodontales en el líquido sinovial en sujetos con EP y AR, asociando la prevalencia de P. gingivalis con el aumento de los niveles de anticuerpos anti-CCP, lo que podría exacerbar los procesos inflamatorios y producir reacciones autoinmunes en AR.
ABSTRACT Introduction: Periodontal disease (PD) and rheumatoid arthritis (RA) are multifactorial chronic inflammatory diseases that share similar aetiopathogenic mechanisms that lead to the destruction of both dental-alveolar tissues and synovial joints, in such way that antibodies against periodontal pathogens have been identified in the crevicular fluid and in the synovial fluid and membranes. Objective: To identify, recover, critically analyze and synthesize the available literature on the prevalence of periodontal microorganisms in synovial fluid of patients with RA. Materials and methods: A systematic search was performed in MEDLINE, ScienceDirect, SciELO and Google Scholar using the medical subject headings "Rheumatoid arthritis", "periodontal microorganisms" and "synovial fluid". Articles were included that described the presence of isolated periodontal pathogens in synovial fluid of patients diagnosed with RA. The search was closed in February 2017 and was performed using PRISMA methodology. The OSTEBA critical reading sheets were used to assess the external validity and level of evidence of each article in terms of methodological rigor. Results: A total of 14 publications were included that described the presence of periodontal pathogens in synovial fluid of patients with PD and RA. Seven publications detected periodontal pathogens in synovial fluid, with P. gingivalis being positive in all of them. Conclusions: The included studies provided evidence of the presence of periodontal microorganisms in the synovial fluid in subjects with PD and RA, associating the prevalence of P. gingivalis with increased levels of anti-cyclic citrullinated peptide (anti-CCP) antibodies, which could exacerbate inflammatory processes and produce autoimmune reactions in RA.

Early childhood caries (ECC) affect children less than 71 months of age (1) and it represents a public health problem in countries worldwide (24). The mean ECC prevalence in United Nations Countries was 23.8% in children younger than 36 months and 57.3% in children aged 36 to 71 months. East Asia and Latin America and the Caribbean were the worst affected by ECC among children aged 36 to 71 months (5). Dental caries pertains to a group of diseases that are estimated "complex" or "multifactorial," with no single origin pathway (6) and it is resulted by the interaction of bacteria, mainly Streptococci mutans (SM) and actobacilli (LB), and sugary foods on tooth enamel (6,7). Additionally, there must be a lack of oral hygiene and lack of use of fluoride (8).
RESUMO
Resumen Introducción. La periodontitis es una enfermedad infecciosa que afecta los tejidos de soporte del diente y se asocia con diferentes enfermedades sistémicas, incluida la enfermedad cardiovascular. Los estudios microbiológicos permiten detectar microorganismos a partir de muestras subgingivales y cardiovasculares. Objetivo. Describir la microbiota periodontal cultivable y la presencia de microorganismos en válvulas cardiacas de pacientes sometidos a cirugía de reemplazo valvular en una clínica de Cali. Materiales y métodos. Se analizaron 30 muestras subgingivales y de tejidos valvulares mediante cultivo en medio bifásico, agar de sangre con suplemento y agar tripticasa de soya con antibiótico. Las muestras de las válvulas se analizaron mediante reacción en cadena de la polimerasa (PCR) convencional. Resultados. Los patógenos periodontales aislados de bolsas periodontales fueron Fusobacterium ( 50 % ), Prevotella intermedia/nigrescens (40 %), Campilobacter rectus (40 %), Eikenella corrodens (36,7 %), bacilos entéricos Gram negativos (36,7 %), Porphyromonas gingivalis (33,3 %) y Eubacterium (33,3 %). Los agentes patógenos aislados de la válvula aórtica fueron Propionibacterium acnes (12 %), bacilos entéricos Gram negativos (8 %), Bacteroides merdae (4 %) y Clostridium bifermentans (4 %), y de la válvula mitral, P. acnes y Clostridium beijerinckii. La PCR convencional no arrojó resultados positivos para agentes patógenos orales y solo se detectó ADN bacteriano en dos muestras. Conclusiones. La microbiota periodontal de pacientes sometidos a cirugía de reemplazo valvular estaba conformada por especies Gram negativas que han sido relacionadas con infecciones en tejidos extraorales; sin embargo, no se encontraron agentes patógenos periodontales en los tejidos de las válvulas. Aunque hubo muestras de estos tejidos y subgingivales, positivas para bacilos entéricos Gram negativos, no es posible asegurar que tuvieran el mismo origen filogenético.
Abstract Introduction: Periodontitis is an infectious disease that affects the support tissue of the teeth and it is associated with different systemic diseases, including cardiovascular disease. Microbiological studies facilitate the detection of microorganisms from subgingival and cardiovascular samples. Objective: To describe the cultivable periodontal microbiota and the presence of microorganisms in heart valves from patients undergoing valve replacement surgery in a clinic in Cali. Materials and methods: We analyzed 30 subgingival and valvular tissue samples by means of twophase culture medium, supplemented blood agar and trypticase soy agar with antibiotics. Conventional PCR was performed on samples of valve tissue. Results: The periodontal pathogens isolated from periodontal pockets were: Fusobacterium nucleatum (50%), Prevotella intermedia/ nigrescens (40%), Campylobacter rectus (40%), Eikenella corrodens (36.7%), Gram negative enteric bacilli (36.7%), Porphyromonas gingivalis (33.3%), and Eubacterium spp. (33.3%). The pathogens isolated from the aortic valve were Propionibacterium acnes (12%), Gram negative enteric bacilli (8%), Bacteroides merdae (4%), and Clostridium bifermentans (4%), and from the mitral valve we isolated P. acnes and Clostridium beijerinckii. Conventional PCR did not return positive results for oral pathogens and bacterial DNA was detected only in two samples. Conclusions: Periodontal microbiota of patients undergoing surgery for heart valve replacement consisted of species of Gram-negative bacteria that have been associated with infections in extraoral tissues. However, there is no evidence of the presence of periodontal pathogens in valve tissue, because even though there were valve and subgingival samples positive for Gram-negative enteric bacilli, it is not possible to maintain they corresponded to the same phylogenetic origin.

BACKGROUND: Metabolic syndrome (MetS) is a common chronic condition that increases the cardiovascular disease risk and is also linked to periodontitis. The study aim was to determine if a relationship exists between MetS and chronic periodontitis in adult Colombians. METHODS: Participants were 220 healthy-gingivitis subjects and 431 periodontitis patients coming from the three largest Colombian cities. Periodontal status and MetS were determined in subjects. Univariate analysis and odds ratio were calculated within the 95 % confidence intervals and chi2 test compared the groups. Variables were compared among the clinical periodontal groups and MetS by Wilcoxon and multivariate analysis, and logistic regression was performed for MetS and periodontitis. RESULTS: MetS had higher prevalence in periodontitis group (6.3 %) versus controls (3.2 %). In multivariate analysis, periodontitis was associated with MetS (adjusted OR = 2.72, 95 % CI 1.09-6.79), glucose intolerance with another component of MetS (adjusted OR = 1.78, 1.16 to 2.72), glucose resistance (adjusted OR = 11.46, 95 % CI 1.41-92.88), smoking (OR = 1.72, 95 % CI 1.09-2.71), and city of origin (2.69, 95 % CI 1.79-4.04). CONCLUSION: The study confirmed the positive association between MetS and periodontitis, being glucose sensitivity the strongly associated component. CLINICAL RELEVANCE: MetS must be taken into account by the dentist when evaluating risk factors for periodontitis, being useful for dentists to evaluate glycemia, lipidic profile, central obesity, and high blood pressure in patients. Interdisciplinary treatment must be recommended when a patient with MetS and periodontitis is being treated.
