Impact of oral condition on the quality of life of homeless people

OBJECTIVE: To describe the prevalence of oral health impact on quality of life and its association with the dental condition and sociodemographic factors of homeless people. METHODS: The sample was composed of 116 adults, temporarily attended by a public institution in the municipality of Goiânia, state of Goiás. Interviews were carried out including the Oral Impact on Daily Performance instrument and sociodemographic aspects. Clinical examinations were done by a trained examiner considering criteria of the World Health Organization. We evaluated dental caries (DMFT index) and use or need to use some type of prosthesis. For the statistical analysis of data, we used Pearson’s Chi-square and Fisher’s exact tests and Poisson regression with robust variance. RESULTS: Of the total respondents, 81.9% had at least one daily performance affected by dental problems in the six months prior the survey. The most prevalent dental conditions were: need for lower arch (76.7%) and upper arch prosthesis (69.0%); untreated caries (75.9%); and high DMFT (57.8%). In bivariate analysis, only the need for upper prosthesis variable was associated with the impact (high Oral Impact on Daily Performance). In the regression model, adjusted for time in the institution, age, and sex, this association remained significant (p = 0.015). Individuals without need for upper prosthesis had prevalence of high impact on daily performance 55% lower than those in need of this type of prosthesis (p = 0.018). CONCLUSIONS: The prevalence of oral health impact on quality of life of homeless people was high and higher than that verified in the overall Brazilian population. The impact was associated with the need for upper prosthesis, regardless of sociodemographic characteristics of the individuals

Peritonite bacteriana espontânea causada por Listeria monocytogenes em pacientes com cirrose: primeiro relato de caso no Brasil

Two cases of spontaneous bacterial peritonitis (SBP) caused by Listeria monocytogenes in cirrhotic patients are reported. In one of the cases, the microorganism was isolated from pleural effusion and ascites. SBP is a serious and common complication of patients with ascites caused by hepatic cirrhosis and the culture of the ascitic fluid is an important tool for the diagnosis and for the more appropriate treatment. Although a third generation cephalosporin has usually been employed for empiric treatment of SBP, it does not provide adequate coverage against Listeria spp. In such cases the use of ampicillin (with or without sulbactam) or sulfamethoxazole-trimethoprim is recommended. The last one is used for secondary prophylaxis, instead of norfloxacin. To summarize, Listeria monocytogenes infection is a rare cause of SBP, whose treatment should be specific for the bacteria.Foram relatados dois casos de peritonite bacteriana espontânea (PBE) por Listeria monocytogenes em pacientes com cirrose. Em um dos casos isolamos também o agente no líquido pleural. A PBE é uma complicação comum e grave de pacientes com ascite por cirrose e a cultura do líquido ascítico é de grande importância para o diagnóstico e para o tratamento mais adequado. Embora uma cefalosporina de terceira geração seja geralmente utilizada para o tratamento empírico da PBE, ela não oferece cobertura adequada contra a Listeria spp. Nesses casos, recomenda-se o uso de ampicilina (com ou sem sulbactam) ou sulfametoxazol-trimetoprim. Para a profilaxia secundária indica-se o uso deste último, ao invés da norfloxacina. Em resumo, a infecção por Listeria monocytogenes é uma causa rara de PBE e o tratamento específico deve ser administrado

The challenge of long-distance over-the-air wireless links in the ocean: a survey on water-to-water and water-to-land miot communication

Robust wireless communication networks are a cornerstone of the modern world, allowing data to be transferred quickly and reliably. Establishing such a network at sea, a Maritime Internet of Things (MIoT), would enhance services related to safety and security at sea, environmental protection, and research. However, given the remote and harsh nature of the sea, installing robust wireless communication networks with adequate data rates and low cost is a difficult endeavor. This paper reviews recent MIoT systems developed and deployed by researchers and engineers over the past few years. It contains an analysis of short-range and long-range over-the-air radio-frequency wireless communication protocols and the synergy between these two in the pursuit of an MIoT. The goal of this paper is to serve as a go-to guide for engineers and researchers that need to implement a wireless sensor network at sea. The selection criterion for the papers included in this review was that the implemented wireless communication networks were tested in a real-world scenario.cofunded by the project K2D: Knowledge and Data from the Deep to Space with reference POCI-01-0247-FEDER-045941, cofinanced by the European Regional Development Fund (ERDF), through the Operational Program for Competitiveness and Internationalization (COMPETE2020), and by the Portuguese Foundation for Science and Technology (FCT) under the MIT Portugal Program.

Supressão de plantas daninhas pelo efeito da cobertura com Pennisetum purpureum e esterco de aves na cultura do gergelim

The sesame (Sesamum indicum) has great potential for southern Santa Catarina, but the expansion of the crop faces a problem in management, especially due to weed infestation. Therefore, the objective of this work was to evaluate the effect of poultry manure and different layers of napier grass (Pennisetum purpureum) on the suppression of weeds and sesame production components. The treatments were arranged in a factorial scheme (3x2), with factor A composed of different coverage layers (0, 2 and 4cm); and factor B by doses of poultry manure (0 and 3kg m-2). The evaluated variables were: weed identification and weed dry phytomass, at 15 and 30 days after seedling transplanting (DAT); and number of capsules and dry phytomass of crop. The increment of the level of mulching in the soil reduces the weed dry phytomass, increases the number of capsules and the dry phytomass of sesame, while the fertilization of poultry manure (3kg m-2) does not interfere with the evaluated components.O gergelim (Sesamum indicum) apresenta grande potencial para cultivo no sul catarinense, mas a ampliação no plantio é dificultada por problemas de manejo, especialmente relacionados ao controle de plantas daninhas. Diante disso, o objetivo do trabalho foi avaliar o efeito do esterco de aves e diferentes camadas de cobertura de capim-elefante (Pennisetum purpureum) na supressão de plantas daninhas e componentes de produção do gergelim. Os tratamentos foram dispostos em esquema fatorial (3x2), sendo o fator A composto por diferentes espessuras de cobertura vegetal (0, 2 e 4cm); e o fator B por doses de esterco de aves (0 e 3kg m-2). As variáveis avaliadas foram: identificação e fitomassa seca da parte aérea das plantas daninhas, aos 15 e 30 dias após transplante (DAT) das mudas; e contagem do número de cápsulas e fitomassa seca da cultura. O incremento do nível de palha no solo reduz a fitomassa seca da parte aérea das plantas daninhas, aumenta o número de cápsulas e fitomassa seca do gergelim, enquanto que a adubação com esterco de aves (3kg m-2) não interfere nos componentes avaliados

Analgesic action of laser therapy (LLLT) in an animal model

Objectives: To evaluate the analgesic effect of laser therapy on healthy tissue of mice. Study design: Forty-five animals were divided in three groups of 15: A ? infrared laser irradiation (830 nm, Kondortech®, São Carlos, SP, Brazil); B ? red laser irradiation (660 nm, Kondortech®, São Carlos, SP, Brazil); C ? sham irradiation with laser unit off. After laser application, the mice remained immobilized for the injection of 30 µl of 2% formalin in the plantar pad of the irradiated hind paw. The time that the mouse kept the hind paw lifted was measured at 5 min intervals for 30 minutes. Results: Results showed statistically significant differences comparing the control group with the infrared laser group at 5, 20, 25 and 30 accumulated minutes, and with the red laser group at all time points. The analysis of partial times, at each 5 minutes, showed statistically significant differences between the control and the laser groups up to 20 minutes. Conclusions: Laser therapy had an analgesic effect and red laser had the best results

Reconstrução de assoalho orbital com polietileno de alta densidade

Surgical interventions in blow out fractures are generally indicated in cases of alterations in orbital function (e.g. diplopia)and for aesthetic reasons (e.g. enophthalmos). In assessing the severity of the injury, the clinician often uses parameterssuch as changes in visual acuity, patient-reported diplopia, changes in globe position and evaluation of the extraocularmuscles in association with imaging exams. Computed tomography has been the modality of choice for detailed imagingdiagnosis and surgical planning of orbital trauma. High density polyethylene may be successfully used in orbital floorreconstruction to restore function and esthetics. Taking into account the follow up of six months, the availability and theadvantages of high density polyethylene implants, it can be concluded that their use in reconstruction of orbital floordefects is a good choice.Justifica-se intervir cirurgicamente em fraturas do tipo blow out naqueles casos em que haja alterações da função orbital,como a diplopia, ou mesmo por razões estéticas, como a enoftalmia. Clinicamente, as fraturas do tipo blow out revelamalterações estéticas e funcionais que, associadas aos exames complementares por imagem, como a tomografiacomputadorizada, indicam o procedimento cirúrgico reparador. A utilização do polietileno de alta densidade (PAD) nareconstrução do assoalho orbital reduz a morbidade do enxerto autógeno, apresentando estabilidade e biocompatibilidade.Este artigo discute um caso cirúrgico de evolução favorável após seis meses de reconstrução do assoalho orbital com PAD

Componentes do balanço de energia da soja estimada por meio de imagens via satélite.

Existem várias formas para mensurar a evapotranspiração, desde formas diretas, com a utilização de lisímetros, a indiretas como proposto por Penman-Montheith. Esses métodos podem ser considerados limitados, porque estimam valores pontuais de evapotranspiração para um local específico e não para uma escala mais ampla. Em uma nova perspectiva de trabalho, o emprego do algoritmo denominado Surface Energy Balance Algorithm for Land - SEBAL possibilita estimar os componentes do balanço de energia e evapotranspiração, fazendo uso apenas das radiâncias espectrais registradas em sensores de satélites e de um conjunto mínimo de dados meteorológicos. Objetivou-se com o presente trabalho estimar as componentes do balanço de energia numa lavoura de soja, a partir do algoritmo SEBAL, e comparar com a calculada usando o modelo de Penman-Monteith-FAO. Foram utilizadas duas imagens (órbita 220 e ponto 69), do Mapeador Temático do Satélite LANDTSAT 5 (TM-LANDSAT 5), composta de sete bandas espectrais, obtidas em datas distintas do ciclo da cultura da soja: 06 de janeiro e 07 de fevereiro de 2011, em que a mesma encontrava-se nos estádios fenológicos V9 e R2, respectivamente. Avaliou-se por meio de erros estatísticos o desempenho do SEBAL em estimar a evapotranspiração (ET), e os resultados se mostraram satisfatórios, quando consideradas as condições atmosféricas estáveis, podendo auxiliar na otimização e racionalização do uso da água
