Periodontitis y Alzheimer: posibles mecanismos de vinculación: revisión de la literatura / Periodontitis and Alzheimer: possible linking mechanisms: a review of the literature

La periodontitis es una enfermedad inflamatoria, crónica que afecta a los tejidos de soporte de los dientes y puede repercutir en la salud general, afectando la calidad de vida del paciente. La enfermedad de Alzheimer es una condición neurodegenerativa y progresiva que va disminuyendo la memoria, el lenguaje y aprendizaje de los pacientes. El objetivo de la investigación es realizar una revisión bibliográfica para comprender la posible vinculación entre la periodontitis y el Alzheimer. Los microorganismos periodontopatógenos producen una respuesta inflamatoria que, por vía sistémica, puede desencadenar un mecanismo inflamatorio dentro del sistema nervioso central. La respuesta del hospedero es liberar gran cantidad de moléculas proinflamatorias que comprometen la barrera hematoencefálica sobreestimulando a las células microgliales, esto conduce a la destrucción de neuronas vitales y al mantenimiento de la inflamación crónica que contribuye a la progresión del Alzheimer. Por otra parte, la periodontitis puede favorecer la formación de placas ateromatosas que afectan la integridad vascular siendo éste un factor a considerar en el desarrollo de la patología cerebrovascular. A pesar que son pocos los estudios clínicos experimentales, ya se puede sugerir la correlación entre ambas enfermedades (AU)

Periodontitis is a chronic inflammatory disease that affects the supporting tissues of teeth, affecting the systemic health and quality of life of the patient. Alzheimer's disease is a neurodegenerative and progressive condition that decreases memory, speech and learning of patients. The objective of this literature review was to report the possible link between periodontitis and Alzheimer's disease. Periodontopathogens produce an inflammatory response that, systemically, can trigger an inflammatory mechanism within the central nervous system. Due to this attack, the host releases a great quantity of proinflammatory molecules that compromise the blood-brain barrier by over- stimulation microglial cells, this produces destruction of vital neurons and maintenance the chronic inflammation in CNS and that contribute to the progression of Alzheimer's disease. On the other hand, periodontitis can favor the formation of atheromatous plaques that affect vascular integrity, being a factor to consider in the development of the cerebrovascular disease. Although there are few experimental clinical studies, the correlation between both diseases can already be suggested (AU)

The Retirement Process from the Perspective of Meaningful Social Networks of Retirees / O Processo de Aposentadoria na Perspectiva das Redes Sociais Significativas de Aposentados / El Proceso de Jubilación en la Perspectiva de las Redes Sociales de Jubilados

Abstract Research on retirement have traditionally been centered on the individual perspective of the phenomenon. This qualitative study aimed at understanding the relational dynamics in meaningful social networks during the retirement process, as perceived by members of retirees' networks. Nine people indicated by retirees as members of their social networks (spouses, siblings, friends, and former coworkers) participated in this study. Data collection was performed through the Focus Group technique, and field notes were recorded. Data organization and analysis were based on the Grounded Theory and aided by the Atlas.ti software - Mac version 1.6.0. Results show that retirement triggers a recursive process to break, maintain, or redevelop bonds, with repercussions on the relational issues and proposals among the network of retirees. The study data suggest that the relational dimension greatly affects the retirees' experience as well as their relational network.

Consensus of Chinese stomatological multidisciplinary experts on maintaining periodontal health (First edition) / 中华口腔医学杂志

Periodontal disease is the main cause of tooth loss in adults, and it is also one of the major factors affecting oral and general health. In the process of diagnosing and treating the oral diseases, many subspecialties of stomatology will involve in the maintenance of periodontal tissue health. The Chinese Stomatological Association organized a number of experts in related disciplines to thrash out the present expert consensus in order to enhance the awareness of dental clinicians to maintain the health of periodontal tissues and to standardize the procedures of diagnosis and treatment. The clinicians' abilities in prevention and treatment of oral diseases will be hopefully elevated if the clinicians, especially in such disciplines as prosthodontics, orthodontics, oral implantology, operative dentistry and endodontics, can early recognize and identify the periodontal disease and the damage degree of periodontal tissues, adopt the appropriate intervention measures and predict the prognosis scientifically.

Assessing quality of systematic reviews in dermatology from the Philippines using AMSTAR 2 Part 1: Methodologic quality of dermatological systematic reviews from the Philippines

@#BACKGROUND: Quality systematic reviews (SRs) are essential in the practice of evidence-based dermatology. We assessed the methodologic quality of SRs in dermatology from the Philippines. METHODS: We searched databases (MEDLINE, CDSR, PROSPERO, HERDIN; from inception until June 30, 2019), and secondary sources. We included SRs, authored by Filipino primary authors, which included clinical trials on any intervention for the treatment or prevention of a dermatologic disease or for maintenance of healthy skin, hair or nails. Two reviewers independently extracted data and appraised the methodological quality of each included SR using the AMSTAR 2. The 16-item AMSTAR 2 has 7 critical items and 9 non-critical items. The number of critical items mainly determine the overall confidence in the results of the review. Descriptive analysis using means and standard deviation for continuous data, and frequency and percentage distribution for categorical data were employed. RESULTS: Twenty SRs were included in this review, and were mostly published in the 2010s. Majority of SRs had three authors, who belonged to a single institution, with at least one dermatologist. The most common topic was infections and both oral and topical interventions were used. Majority had 5 included studies in the SRs, with a median number of 425 participants. The median number of critical flaws in the included SRs was 4.5, and non-critical flaws, 5. Overall confidence was critically low in majority (19/20 ) of included reviews, with only one review rated as low. CONCLUSION: The methodologic quality of the dermatology SRs from the Philippines based on the AMSTAR 2 tool was poor with a rating of critically low in majority. There is a need to improve quality of conduct and reporting through dissemination of the reporting guidelines such as the PRISMA

Manutenção de Aedes aegypti e Culex quinquefasciatus (Diptera: culicidae) em condições de laboratório: uma revisão sistemática / Maintenance of Aedes aegypti and Culex quinquefasciatus (Diptera: culicidae) in laboratory conditions: a systematic review

O crescimento populacional no mundo, junto com o aumento desenfreado dos grandes centros urbanos, com condições precárias de saneamento e infraestrutura, favorecem o desenvolvimento e a proliferação de algumas espécies de mosquitos. O comportamento e fácil adaptação de Ae.aegypti favoreceram sua dispersão pelos mais diferentes tipos de ambientes, sendo encontrado principalmente no intra e peridomicílio, onde há elevada presença humana, abrigos e criadouros potenciais. As fêmeas possuem hábito alimentar diurno, sendo os picos de maior atividade no amanhecer e durante o crepúsculo vespertino. Entretanto, podem picar o homem e outros animais a qualquer hora do dia, pois são muito oportunistas. No Brasil, a grande importância de Ae. aegypti se dá ao fato de ser considerado o principal vetor da febre amarela urbana, dengue, chikungunya e Zika. Já o mosquito Culex quinquefasciatus geralmente está relacionado em áreas de saneamento precário, próximo às zonas periféricas. As fêmeas também são hematófagas e estão associadas aos locais de habitações humanas, onde encontram abrigo, criadouros e fontes de alimentação. Possuem hábitos noturnos e crepusculares e, eventualmente, podem picar durante o dia. A presença deste mosquito na área urbana gera desconforto ao ser humano, causando irritação e diminuição da qualidade de vida, devido ao incômodo causado pelas picadas e perturbação noturna. Além disso, algumas áreas infestadas por Cx. quinquefasciatus são propícias a problemas relacionados com saúde pública, pois esse mosquito é considerado vetor de agentes patogênicos, como a filaríase bancroftiana, causada pelo verme Wuchereria bancrofti. A manutenção de insetos em laboratório, assim como outros animais, possibilita entender melhor sua biologia, dinâmica de populações, desenvolvimento das espécies e melhores condições para confinamento e reprodução. Procedimentos de alimentação, reprodução e acondicionamento de mosquitos são alguns dos principais elementos para o desenvolvimento de colônias em larga escala em laboratório, além das condições ambientais, como temperatura, umidade e fotoperíodo. Formas imaturas de Ae. aegypti e Cx. quinquefasciatus podem ser mantidas para desenvolvimento nos mais variados tipos de recipientes. A manutenção de mosquitos adultos em laboratório é realizada através do confinamento destes insetos em gaiolas teladas, que podem variar de tamanho e material. A fonte alimentar para machos e fêmeas adultas de mosquitos se dá a partir de soluções açucaradas. Para reprodução de mosquitos em laboratório é essencial o fornecimento de alimentação sanguínea para fêmeas adultas, pois somente dessa forma haverá a maturação dos ovos. Alimentadores artificiais vêm sendo desenvolvidos e utilizados constantemente em procedimentos para manutenção de mosquitos em laboratório, sendo alguns mais complexos e outros mais simples. Estes alimentadores, normalmente, são compostos por um ou mais reservatórios sanguíneos, onde é estocado o volume de sangue para alimentação das colônias de insetos. Geralmente, estes reservatórios são cobertos por membranas finas que facilitam a penetração e alimentação dos mosquitos. Nesta revisão, foi observado que a maioria das técnicas para alimentação sanguínea artificial de mosquito, apresentaram bons resultados em relação a taxa de alimentação, fecundidade e sobrevivência dos insetos, sendo assim, uma boa alternativa para manutenção de colônias de Ae.aegypti e Cx.quinquefasciatus em laboratório.

The population increase in the world, with the increase in large urban areas, with poor sanitation and infrastructure conditions, favor the development and proliferation of some species of mosquitos. The behavior and easy adaptation of Ae. aegypti favored its dispersion in the most different types of environments, being found mainly within and around the home, where there is a high human presence, shelters and potential breeding sites. Females have diurnal eating habits, with the highest activity peaks at dawn and during evening twilight. However, they can bite man and other animals at any time of the day, as they are very opportunistic. In Brazil, the great importance of Ae. aegypti is due to the fact that it is considered the main vector of urban yellow fever, dengue, chikungunya and Zika. The Culex quinquefasciatus mosquito is generally found in areas of poor sanitation, near to peripheral areas. Females are also hematophagous and are associated with human habitation sites, where they find shelter, breeding grounds and source of food. They have nocturnal and twilight habits and, eventually, they can bite during the day. The presence of this mosquito in the urban area generates discomfort to humans, causing irritation and decreased quality of life, due to the discomfort caused by the bites and night disturbance. In addition, some areas infested by Cx. quinquefasciatus are conducive to problems related to public health, as this mosquito is considered a vector of pathogens, such as bancroftian phyliasis, caused by the Wuchereria bancrofti worm. The maintenance of insects in the laboratory, as well as other animals, makes it possible to better understand their biology, population dynamics, species development and the best conditions for confinement and reproduction. Procedures for feeding, breeding and conditioning mosquitos are some of the main elements for the development of large-scale colonies in the laboratory, in addition to environmental conditions such as temperature, whet and photoperiod. Immature forms of Ae. aegypti and Cx. quinquefasciatus can be kept for development in the most varied types of containers. The maintenance of adult mosquitoes in the laboratory is carried out by confining these insects in screened cages, which can vary in size and material. The food source for adult male and female mosquitoes is from sugary solutions. For reproduction of mosquitoes in the laboratory, it is essential to provide blood supply to adult females, as only in this way will the eggs mature. Artificial feeders have been developed and used constantly in procedures for maintenance mosquitos in the laboratory, some of which are more complex and others simpler. These feeders are usually composed of one or more blood reservoirs, where the volume of blood is stored to feed insect colonies. Generally, these depot are covered by thin membranes that facilitate the penetration and feeding of mosquitoes. In this review, it was observed that most techniques for artificial mosquito blood feeding, showed good results in relation to the feeding rate, fertility and survival of insects, this offer a good option for maintenance colonies of Ae.aegypti and Cx. quinquefasciatus in laboratory.

Avaliação imunológica promovida pelo consumo de kombucha em camundongos diabéticos / Immunologic evaluation promoted by the consumption of kombucha in diabetic mice

O kombucha é uma bebida fermentada tradicional, originária da China, preparada pela fermentação de chá preto adoçado com cultura mista de bactérias e leveduras chamada Simbiotic Culture of Bacteria and Yeast (SCOBY). Tem sido alegado que o mesmo possui propriedades funcionais, tais como recuperação ou manutenção de peso corporal, atividade antihiperglicêmica, entre outras. Por não existirem estudos suficientes que as comprovem, este trabalho teve por objetivo avaliar a influência do consumo de kombucha como tratamento alternativo para amenizar e/ou retardar sintomas e complicações do Diabetes Mellitus e identificar as possíveis modificações metabólicas, morfológicas e imunológicas ocorridas em camundongos com diabetes tipo 1. De acordo com os resultados obtidos, observou-se que, apesar de ter havido recuperação de massa corpórea próxima daquela que se tinha antes da indução da diabetes, esse efeito não foi exclusivo do kombucha e, embora a influência no controle glicêmico tenha sido maior nos camundongos normoglicêmicos que diabéticos, acredita-se que a administração por um período prolongado pudesse indicar melhores resultados, uma vez que as avaliações histológicas e morfométricas do intestino demonstraram resultados satisfatórios quanto ao aumento da superfície de mucosa e diminuição do infiltrado inflamatório, favorecendo a modulação imunológica. Logo, considera-se necessária a realização de mais trabalhos para comprovação da capacidade funcional do kombucha e elucidação de sua eficácia enquanto tratamento exclusivo e/ou complementar do diabetes

Kombucha is a traditional Chinese fermented beverage prepared by fermenting sweetened black tea with mixed bacterial and yeast culture called Simbiotic Culture of Bacteria and Yeast (SCOBY). It has been claimed that it has functional properties such as body weight recovery or maintenance, antihyperglycemic activity, among others. Because there are not enough studies to prove them, this study aimed to evaluate the influence of kombucha consumption as an alternative treatment to alleviate and/or delay symptoms and complications of Diabetes Mellitus and to identify possible metabolic, morphological and immunological changes in mice with type 1 diabetes. According to the results obtained, it was observed that, although there was a recovery of body mass close to the one obtained before diabetes induction, this effect was not unique to kombucha, and although the influence on glycemic control was greater in normoglycemic rather than diabetic mice, it is believed that administration over a prolonged period could indicate better results, since histological and morphometric evaluations of the intestine showed satisfactory results in terms of mucosal surface enlargement and decreased inflammatory infiltrate, favoring immune modulation. . Therefore, further work is considered necessary to prove the functional capacity of kombucha and to elucidate its effectiveness as an exclusive and / or complementary treatment of diabetes

Estudos funcionais e biológicos associados à interação de DUSP3 com a proteína HNRNPC1/C2 / Functional and biological studies associated to DUSP3 and HNRNPC1/C2 protein inte ractions

A regulação da fosforilação/desfosforilação das proteínas é o eixo central de muitas cascatas de sinalização. A fosfatase DUSP3, constituída apenas por um único domínio catalítico, desempenha papéis fundamentais na proliferação e senescência celular. Nas células HeLa, submetidas ao estresse genotóxico, o DUSP3 interage fisicamente com as proteínas HNRNPC, mas o efeito dessa função molecular ainda é desconhecido. Aqui demostramos que a ausência de DUPS3 mantem a proteína HNRNPC1/C2 num estado hiperfosforilado. Para entender melhor o envolvimento da interação DUSP3-HNRNPC nas funções biológicas da HNRNPC1/C2, foram estudadas células de fibroblasto deficientes de DUSP3. Foi analisado o efeito da deficiência de DUSP3 na biogênese dos ribossomos através do ensaio de perfil de polirribossomos e quantificação dos rRNAs com RT-qPCR. Os resultados mostraram que a deficiência de DUSP3 não afeta a maturação das subunidades ribossômicas, mas teria um impacto na transcrição dos pré-rRNAs e no acumulo das espécies 47S/45S. A expressado de genes contendo sequencias IRES foi analisado através do RT-qPCR e sua tradução ao longo do ciclo e em condições de estresse. Da expressão, não existe nenhuma diferença nos níveis de transcrição dos genes c-myc e xiap nas células normais e deficientes de DUSP3 em condições basais. Embora a síntese destas proteínas é maior nas células deficientes, mantendo um nível maior de tradução ao longo de todo o ciclo. Sob condições de estresse, esta duas proteínas sempre mantem uma maior expressão nas células Knockdown para DUSP3. Neste trabalho também foi estabelecido a presença de DUSP3 nos complexos da subunidade 40S, através do analise das frações obtidas do ensaio de polirribossomos e interação in vitro (Co-IP). A presença de DUSP3 nas subunidades 40S, os monossomas 80S e polissomos poderia ser através da interação direta com proteínas que possuem um domínio RRM e seria dependente dos complexos formados pelas proteínas e seus RNAs alvos. Aqui mostramos a interação in vitro de DUSP3 com a proteína PABP (com quatro domínios RRM), proteína que tem um papel importante na manutenção da taxa global de tradução, esta interação é enfraquecida na ausência de RNAs. A deficiência de DUSP3 também teria um impacto na interação das proteínas HNRNPC1/C2 e P53 in vitro. A ausência de DUSP3 diminui a interação HNRNPC-P53 através da hiperfosforilação da proteina HNRNPC1/C2. A perda desta interação, aumentaria os níveis da proteína P53 na célula deficiente de DUSP3 e poderia gerar parada no ciclo celular. Através de ensaios de imunofluorescência, se observo uma maior taxa de transcrição global na célula deficiente de DUSP3. Por fim, aqui demostramos que a interação direta de DUSP3 e HNRNPC1/C2 vai permitir a regulação das funções biológicas desta proteína, e a ausência de DUSP3 vai ter efeitos pleiotrópicos na homeostase da célula

inglêsProtein phosphorylation/dephosphorylation regulation is a central axis of many signaling cascades. DUSP3 phosphatase, consisting only of a single catalytic domain, plays key roles in cell proliferation and senescence. In HeLa cells subjected to genotoxic stress, DUSP3 physically interacts with HNRNPC proteins, but the effect of this molecular function is still unknown. Here we demonstrate that the absence of DUPS3 keeps the HNRNPC1/C2 proteins in a hyperphosphorylated state. To better understand the involvement of DUSP3- HNRNPC interaction on the biological functions of HNRNPC1/C2, DUSP3 deficient fibroblast cells were studied. The effect of DUSP3 deficiency on ribosome biogenesis was analyzed by polyribosome profile assay and RT-qPCR for rRNA quantification. The results showed that DUSP3 deficiency does not affect ribosomal subunit maturation, but would have an impact on transcription of pre-rRNAs and accumulation of 47S / 45S species. The expression of genes containing IRES sequences was analyzed by RT-qPCR and their translation throughout the cycle and under stress conditions. From expression, there is no difference in transcriptional levels of c-myc and xiap genes in normal and DUSP3 deficient cells under basal conditions. Although, the synthesis of these proteins is higher in deficient cells and these maintain a higher level of translation throughout the cell cycle. Under stress conditions, these two proteins always maintain higher expression in Knockdown cells for DUSP3. In this work, the presence of DUSP3 in the 40S ribosomal subunit complexes was also established by analyzing the fractions obtained from the polyribosome assay and in vitro interaction (CoIP). The presence of DUSP3 in the 40S subunits, 80S monosomes and polysomes could be through direct interaction with proteins that have an RRM domain and would be dependent on the complexes formed by the proteins and their target RNAs. Here we show the in vitro interaction of DUSP3 with PABP protein (with four RRM domains), a protein that plays an important role in maintaining the overall translation rate, this interaction is weakened in the absence of RNAs. DUSP3 deficiency would also have an impact on the interaction of HNRNPC1/C2 and P53 proteins in vitro. The absence of DUSP3 decreases HNRNPC-P53 interaction through hyperphosphorylation of the HNRNPC1/C2 proteins. Loss of this interaction would increase P53 protein levels in the DUSP3 deficient cell and could lead to cell cycle arrest. Through immunofluorescence assays, a higher overall transcription rate is observed in the DUSP3 deficient cell. Finally, we demonstrate that the direct interaction of DUSP3 and HNRNPC1/C2 will allow the regulation of the biological functions of this protein, and the absence of DUSP3 will have pleiotropic effects on cell homeostasis

Breakdown of complications related to the use of central venous catheters in intensive therapy units / Desfecho das complicações relacionadas ao uso de cateteres venosos centrais em unidades de terapia intensiva

The ICU is a highly complex sector, and among the wide range of interventions performed in the intensive care patient, we highlight the use of the central venous catheter (CVC). Maintaining the CVC requires knowledge and ability to ensure safe and long-lasting vascular access. However, during the permanence time of the device, some complications related to the catheter material, caliber, puncture site, dressing used, type of medication administered and length of stay may occur. Knowing the possible complications that occur with the catheter during its stay and the outcome of these complications favors the health professional in the elaboration of prevention strategies. Therefore, this research aims to elucidate the occurrence of non-elective removal, the main complications and outcomes related to the use of CVC in clients hospitalized in the ICU. This is a descriptive, observational, prospective study with a quantitative approach. The study was carried out in a teaching hospital in Uberaba-MG, from March to August 2016. The population of the study consisted of CVCs inserted in clients hospitalized in the ICUs. As a result, 75 (38.3%) catheters presented complications, being the outcome of 55 (73.3%) non-elective removal when the complication was discovered. The other 121 (61.7%) catheters had the outcome of removal on discharge from the client to the ward 59 (48.7%), death of the client 25 (20.6%), discharge from the client to the ward with the device (Risk benefit) 27 (22.3%) and removal at the physician's discretion 10 (8.2%). The permanence time of the device was 7.65. The greater the number of complications the catheter presented, the greater the chances of catheter loss (63.4). This study emphasizes the importance of conducting other studies that may contribute to the reduction of complications resulting from the use of CVC, and emphasize that complications demand higher expenses for the health system and increase the risk of infection of clients hospitalized in the ICU.

A UTI é um setor de alta complexidade, dentre a vasta gama de intervenções realizadas no cliente dentro da terapia intensiva destacamos o uso do cateter venoso central (CVC). A manutenção do CVC exige conhecimento e habilidade para garantir um acesso vascular seguro e duradouro. No entanto, durante o tempo de permanência do dispositivo algumas complicações relacionadas ao material do cateter, calibre, local de punção, curativo utilizado, tipo de medicamento administrado e tempo de permanência podem acontecer. Conhecer as possíveis complicações que ocorrem com o cateter durante a sua permanência e o desfecho dessas complicações favorece o profissional de saúde na elaboração de estratégias de prevenção. Diante disso, essa pesquisa tem por objetivo elucidar a ocorrência de retirada não eletiva, as principais complicações e os desfechos relacionados à utilização do CVC nos clientes internados na UTI. Trata-se de um estudo descritivo, observacional, prospectivo, com abordagem quantitativa. A pesquisa foi desenvolvida em um Hospital de ensino de Uberaba-MG no período de março a agosto de 2016. A população do estudo foi constituída por CVC inseridos em clientes internados nas UTI's. Como resultado 75 (38,3%) cateteres apresentaram complicações, onde o desfecho de 55 (73,3%) foi à retirada não eletiva frente à descoberta da complicação. Os outros 121 (61,7%) cateteres tiveram como desfecho a retirada na alta do cliente para enfermaria 59 (48,7%), o óbito do cliente 25 (20,6%), a alta do cliente para enfermaria com o dispositivo (risco benefício) 27 (22,3%) e a retirada a critério médico 10 (8,2%). O tempo de permanência do dispositivo foi de 7,65. Quanto maior foi o número de complicações que o cateter apresentou, maiores foram às chances de perda do cateter (63,4). Este estudo vem destacar a importância da realização de outras pesquisas que possam contribuir para redução de complicações advindas do uso do CVC, e ressaltar que as complicações demandam maiores gastos para o sistema de saúde e aumentam os riscos de infecção dos clientes internados na UTI.

Analysis of the Insertion of Particular Photovoltaic Generation in the Low Voltage Installations, Under the Approach to Performance, Safety, Maintenance and Operation of the PVS

ABSTRACT The growing use of Photovoltaic Solar Energy in Brazil, both in power plants and in distributed generation systems, brings with it a series of practical and technical questions that are not limited to the design and project of the systems. Environmental factors and resources related to the use, operation, maintenance, decommissioning and final disposal of the equipment and components that constitute them, should be taken into consideration, so that these systems maintain an adequate performance during their lifespan granting the safety for users, properties and avoid negative environmental impacts. Within the concept of Risk Analysis within the Life Cycle of these systems, the present study addresses a perspective of the growth of the use of Solar Photovoltaic Energy in Brazil and the risks and impacts resulting from the lack of information on how good practices for a maintenance of its facilities, its performance, safety and sustainability of Photovoltaic Solar Power Generation Systems.
