AVALIAÇÃO CLÍNICA DO PERIODONTO EM DENTES RETENTORES DE PRÓTESE PARCIAL REMOVÍVEL / PERIODONTAL CLINICAL EVALUATION OF REMOVABLE PARTIAL DENTURE'S SUPPORTING TEETH

Introdução: A prótese parcial removível é uma opção reabilitadora e representa um dos meios de reabilitação dental mais aceito, sendo um método terapêutico satisfatório biologicamente e de custo acessível. Objetivo: Avaliar clinicamente os efeitos do uso de próteses parciais removíveis sobre os tecidos periodontais nos dentes suportes diretos. Métodos: Estudo transversal em trinta pacientes assistidos na clínica do curso de Odontologia da Universidade Federal do Maranhão. Na avaliação periodontal foi utilizado o índice de placa, o índice gengival, a profundidade de sondagem, o nível clínico de inserção, a recessão gengival e o grau de mobilidade dentária, utilizando-se sonda periodontal milimetrada tipo Michigan. Para a análise dos dados coletados, utilizou-se a análise descritiva. Resultados: Observou-se um maior acúmulo de placa e maior frequência de inflamação gengival nas faces interproximais. Dos dentes avaliados, 55,1% exibiram recessão gengival e 11,9% exibiram mobilidade (a maioria estava em próteses de extremo livre). Com relação à profundidade de sondagem e ao nível clínico de inserção, a maioria dos suportes diretos apresentou-se com saúde periodontal. Conclusão: A prótese parcial removível pode contribuir para a retenção de biofilme e no comprometimento periodontal, mas seu uso não é inviável, desde que sejam tomados os cuidados adequados com planejamento, execução, higienização e manutenção.Palavras-chave: Prótese Parcial Removível. Dente Suporte. Periodonto.AbstractIntroduction: Removable partial denture is a rehabilitative option and represents one of means of dental rehabilitation more accepted. It has been a biologically suitable and affordable therapeutic method. Objective: To evaluate the clinical effects of the use of removable partial dentures on periodontal tissues of the direct supporting teeth. Methods: Cross-sectional study with thirty individuals assisted in the clinic of the dentistry course of the Federal University of Maranhão. Periodontal plaque index, gingival index, probing depth, clinical attachment level, gingival recession and the degree of tooth mobility were used in the periodontal evaluation. The Michigan periodontal probe was used. For data analysis we used the descriptive analysis. Results: There was a greater accumulation of plaque and more gingival inflammation in the interproximal surfaces. Among the teeth evaluated, 55.1% showed gingival recession and 11.9% exhibited mobility (with the most of them in prostheses of distal end free). Regarding probing depth and clinical attachment level, most direct supporting teeth presented with periodontal health. Conclusion: The removable partial denture may contribute to the retention of biofilm and periodontal impairment, but its use is not unfeasible, since there are proper cares of planning, implementation, hygiene and maintenance.Keywords: Removable Partial Denture.

ESTRATÉGIAS DE ANASTOMOSE EM CIRURGIA COLORRETAL: UMA ANÁLISE TÉCNICA E COMPARATIVA

This article presents a technical and comparative analysis of anastomotic strategies in colorectal surgery. Colorectal surgery plays a crucial role in the treatment of various conditions, such as colorectal cancer, diverticular disease, and inflammatory bowel disease. Colorectal anastomoses are fundamental procedures in this context, allowing for the reconstruction of the gastrointestinal tract following the resection of colon or rectal segments. In this article, we discuss the indications for colorectal anastomosis, anastomotic techniques, materials and instruments used, comparison of techniques and clinical outcomes, risk factors and preventive measures, challenges and innovations, postoperative considerations and follow-up, and future perspectives. The adopted methodology was an integrative literature review, using search and selection criteria for articles relevant to the topic of colorectal anastomotic strategies, followed by analysis and synthesis of the findings to provide an overview. Keywords included "colorectal surgery," "intestinal anastomosis," "colorectal anastomosis," "surgical techniques," "intestinal stapling," searching for articles published in databases such as PubMed, Scopus, and Web of Science.Este artigo apresenta uma análise técnica e comparativa das estratégias de anastomose em cirurgia colorretal.

Molecular evidence of Borrelia burgdorferi sensu lato in patients in Brazilian central-western region

Abstract We aimed to detect DNA of Borrelia burgdorferi in whole blood and serum samples of patients with clinical symptoms and epidemiology compatible with Brazilian Lyme-like disease. Four patients with positive epidemiological histories were recruited for the study. Blood samples were collected, screened by serologic testing by ELISA and Western blotting and molecular identification of B. burgdorferi by amplifying a fragment of the conserved gene that synthesizes the hook flagellar flgE. The results showed positive serology and for the first time, the presence of B. burgdorferi sensu lato in humans in the Midwest region of Brazil. The resulting sequences were similar to GenBank corresponding sequences of B. burgdorferi flgE gene. By neighbor-joining the phylogenetic analysis, the flgE sequence of the Brazilian strain clustered in a monophyletic group with the sequence of B. burgdorferi sensu lato under 100% bootstrap support. This study opens up promising perspectives and reinforces the need for additional studies to determine the epidemiological characteristics of the disease, as well as the impact of the prevalence of Brazilian borreliosis in Mato Grosso do Sul State, Brazil

A randomized trial of planned cesarean or vaginal delivery for twin pregnancy

Background: Twin birth is associated with a higher risk of adverse perinatal outcomes than singleton birth. It is unclear whether planned cesarean section results in a lower risk of adverse outcomes than planned vaginal delivery in twin pregnancy.\ud \ud Methods: We randomly assigned women between 32 weeks 0 days and 38 weeks 6 days of gestation with twin pregnancy and with the first twin in the cephalic presentation to planned cesarean section or planned vaginal delivery with cesarean only if indicated. Elective delivery was planned between 37 weeks 5 days and 38 weeks 6 days of gestation. The primary outcome was a composite of fetal or neonatal death or serious neonatal morbidity, with the fetus or infant as the unit of analysis for the statistical comparison.\ud \ud Results: A total of 1398 women (2795 fetuses) were randomly assigned to planned cesarean delivery and 1406 women (2812 fetuses) to planned vaginal delivery. The rate of cesarean delivery was 90.7% in the planned-cesarean-delivery group and 43.8% in the planned-vaginal-delivery group. Women in the planned-cesarean-delivery group delivered earlier than did those in the planned-vaginal-delivery group (mean number of days from randomization to delivery, 12.4 vs. 13.3; P = 0.04). There was no significant difference in the composite primary outcome between the planned-cesarean-delivery group and the planned-vaginal-delivery group (2.2% and 1.9%, respectively; odds ratio with planned cesarean delivery, 1.16; 95% confidence interval, 0.77 to 1.74; P = 0.49).\ud \ud Conclusion: In twin pregnancy between 32 weeks 0 days and 38 weeks 6 days of gestation, with the first twin in the cephalic presentation, planned cesarean delivery did not significantly decrease or increase the risk of fetal or neonatal death or serious neonatal morbidity, as compared with planned vaginal delivery

NEOTROPICAL FRESHWATER FISHES: A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
