RESISTIVIDADE ELÉTRICA EM CONCRETO DE MISTURA PROLONGADA

Este trabalho teve como objetivo avaliar o comportamento da resistividade elétrica volumétrica e superficial em concreto endurecido proveniente de misturas prolongadas por até 8 horas, no qual foram utilizados três tipos distintos de cimentos CP II E 32, CP III 40 RS e CP V ARI. Pode-se concluir que o tipo de cimento influência nos resultados da resistividade elétrica do concreto e que quanto maior for o tempo de mistura, maior será a propensão de corrosão das armaduras protegidas pelo concreto de mistura prolongada

Pilomatricoma Maligno em ovino nativo do Estado de Mato Grosso do Sul

Até o presente momento, são raras as publicações que tratam da ocorrência de pilomatricoma em animais. O pilomatricoma é um tumor que pode ser de origem benigna ou maligna, sendo descrito inicialmente como “epitelioma necrosante e calcificante de Malherbe”. É um tumor de evolução lenta e progressiva, de formato variável, com origem a partir da matriz pilosa. Este relato descreve o caso de uma ovelha de origem nativa, com lesão de aspecto tumoral, de localização na narina direita com consistência firme, coloração vermelho-azulada e 2,5 cm de diâmetro. O exame histopatológico identificou a presença de células tumorais de origem epitelial, com áreas de degeneração. Discreto pleomorfismo, em contraste com alto índice mitótico, dominava o padrão morfológico da lesão. O estroma foi constituído por tecido conectivo, infiltrado por um pequeno número de células inflamatórias. O padrão histopatológico observado no presente caso permitiu caracterizar a massa como pilomatricoma maligno

Análise Multicritério como Suporte a Decisão em Situação de Escassez Hídrica: Estudo de Caso da Sub-Bacia Hidrográfica do Rio Seridó - Rio Grande do Norte - Brasil

A gestão de recursos hídricos em contextos de escassez tem se ampliado e influenciado os mais diversos setores da sociedade. No Brasil, dentre outros estados, o Rio Grande do Norte tem se destacado como um estado inserido, em sua maior parte, no semiárido e com pressões históricas marcando o setor público, de modo a exigir cada vez mais rigor em medidas que possam de forma coerente contribuir para a gestão de um recurso natural que, em secas mais severas, tem se tornado cada vez mais essencial. O presente artigo apresenta a análise e aplicação do método Promethee II como subsídio para gestão da sub-bacia hidrográfica do Rio Seridó – RN (Rio Grande do Norte) - Brasil; percebe-se que tal metodologia pode ser uma alternativa para ser reaplicada em contextos semelhantes ao redor do mundo

Evaluation of genotype on fatty acid profile and sensory of meat of indigenous Pantaneiro sheep and Texel or Santa Inês crossbred finished on feedlot

The genetic diversity of the local breeds can contribute to the maintenance of traits that are economically important to the genetic improvement of sheep. The objective of this study was to evaluate the effect of genotype and sex on the fatty acid profile, shear force, and sensory traits of the longissimus lumborum muscle of lambs. Ninety-six lambs with a weaning weight of 15.21 ± 1.25 kg were finished in feedlot until they reached the slaughter weight of 32 kg. Lambs Pantaneiro male (uncastrated) and female, Texel×Pantaneiro, and Santa Inês×Pantaneiro were used in a completely randomized 2×3 factorial design. Pantaneiro lambs had a higher proportion of C14:0 than Texel×Pantaneiro and Santa Inês×Pantaneiro, while Texel×Pantaneiro had a higher proportion of C18:3ω6. Males had a higher proportion of polyunsaturated fatty acids (PUFA) and ω3. Generally, the meat from all lambs showed high proportion of unsaturated fatty acids (UFA). There was interaction between genotype and sex for C14:1 and C16:1. Santa Inês×Pantaneiro males had a higher proportion of C14:1than Pantaneiro females and Texel×Pantaneiro males and females. Pantaneiro males had a higher C16:1 than Texel×Pantaneiro males and females. The sex had an effect only for tenderness, with tender meat for females. Based on the fatty acid profile, the genotypes were discriminated with high accuracy, with 88.9%, 90.1% and 100% classified correctly for Pantaneiro, Santa Inês×Pantaneiro, and Texel×Pantaneiro, respectively. The use of Pantaneiro sheep for meat production provides the same fatty acids and sensory traits, and the crossbreeding shows a tendency to reduce the proportion of C14:0, C14:1, and C16:1, and to increase the proportion of C18:3ω6, highlighting the Texel×Pantaneiro lambs.info:eu-repo/semantics/publishedVersio

Impact of selective vs routine midline episiotomy and lacerations of the anal sphincter

Introduction: Obstetric anal sphincter tear (OAST) is associated with anal incontinence. Episiotomy was proposed as a form of protection of the anal sphincter at delivery; however, several studies have shown that routine use of episiotomy does not reduce the risk of OAST. Objective: This study aims to analyse whether the reduction in the rate of episiotomy in a school hospital in Brazil was associated with an increase in the incidence of obstetric lacerations of the anal sphincter, in addition to associated factors. Methods: Observational, cross-sectional and retrospective study. We included all vaginal deliveries of single pregnancies, cephalic presentation, from 34 weeks of gestational age, performed in 2011-2012 (liberal episiotomy) and 2015-2016 (restricted episiotomy), and compared in relation to the rate of mediolateral episiotomy and OAST. Results: 4268 births were analysed (2043 in 2011-2012 and 2225 in 2015-2016). The episiotomy rate decreased from 59.4% to 44.2% (p ≤ 0.0001). In 2011-2012, there were 10 obstetric anal sphincter lacerations in 2043 births (0.48%), while in the period 2015-2016 there were 31 lacerations in 2225 births (1.39%). There was interaction when comparing the two periods in relation to the episiotomy and the occurrence of OAST (p ≤ 0.0001). Factors associated with OAST were labor induction and shoulder dystocia. Conclusion: There was an increase in the rate of lacerations of the anal sphincter with use of restrictive episiotomy. However, this increase occurred both in deliveries with and in deliveries without episiotomy

Lesions associated with subclinical laminitis and digital radiographic exam in holstein cows in the transitional period

A laminite subclínica é responsável por grandes prejuízos na pecuária leiteira, sendo o seu diagnóstico de grande relevância para evitar reflexos negativos na produção. Portanto, o objetivo deste trabalho foi relacionar lesões associadas à laminite subclínica no período de transição de vacas da raça Holandês com a ocorrência ou não de sinais radiográficos vinculados a essa enfermidade. As vacas foram avaliadas durante o período de transição e divididas em dois grupos (com e sem sinais de laminite subclínica) de acordo com as lesões associadas a essa enfermidade subclínica. A dinâmica radiológica foi realizada em dois momentos durante o período de transição, com o propósito de determinar possíveis alterações de posicionamento capsular e degeneração óssea da terceira falange (F3). Não foram observados efeitos da presença de lesões associadas à laminite subclínica frente ao posicionamento da terceira falange à cápsula do casco (p>0,05). Diferenças radiográficas significativas (p0,05). Assim, neste estudo, vacas leiteiras no período de transição com lesões associadas à laminite subclínica não apresentaram sinais radiográficos de desalinhamento falangeano ao estojo córneo digital.Subclinical laminitis has been responsible for economic losses in dairy industry; thus, its diagnostic is very important to prevent negative responses to milk production industry. The aim of this study was to identify lesions associated with subclinical laminitis during the transition period with presence or absence of radiographic signs linked to this disease in Holstein cows. The cows were evaluated during the transition period and categorized into two groups (with and without laminitis) according to the lesions associated with this subclinical disease. The radiological dynamic was performed in two target points during the transition period (prepartum and postpartum), with the objective of determining capsular position possible alterations and third phalanx bone degeneration (F3). There was no effect of the presence of lesions associated with subclinical laminitis regarding the position of the third phalanx to the hoof wall (p>0.05). Significant radiographic angular differences (p0.05). Overall, this study did not show radiographic signs of phalangeal misalignment in the hoof of dairy cows with lesions associated with subclinical laminitis during the transition period

Evaluation of clinical course of gamma (P.1) variant of concern versus lineages in hospitalized patients with covid-19 in a reference center in Brazil

The SARS-CoV-2 variant of concern (VOC) gamma (P.1) has increased transmissibility and resulted in elevated hospitalization and mortality rates in Brazil. We investigated the clinical course of COVID-19 caused by gamma and non-VOCs at a reference hospital in Brazil in a retrospective cohort study with nonelderly hospitalized patients from two periods, before and after the emergence of gamma. Cohort 1 included patients from both periods whose samples would be eligible for whole-genome sequencing (WGS). Cohort 2 was composed of randomly selected patients from Cohort 1 whose samples were submitted to WGS. A total of 433 patients composed Cohort 1: 259 from the first and 174 from the second period. Baseline characteristics were similar, except for a higher incidence of severe distress respiratory syndrome at admission in patients from the second period. Patients from the second period had significantly higher incidence rates of advanced respiratory support (adjusted hazard ratio [aHR]: 2.04; 95% confidence interval [CI], 1.60–2.59), invasive ventilatory support (aHR: 2.72; 95% CI: 2.05–3.62), and 28-day mortality from the onset of symptoms (aHR: 2.62; 95% CI: 1.46–4.72). A total of 86 (43 gamma and 43 non-gamma) patients composed Cohort 2. Patients with confirmed gamma VOC infections had higher advanced ventilatory support and mortality rates than non–gamma-infected patients. Our study suggests that non-elderly patients hospitalized for COVID-19 in the second period (used as a proxy of gamma infection) had a more severe clinical course. This might have contributed to higher hospitalization and death rates observed in the second wave in Brazil

Effectiveness of hybrid robotic rehabilitation system on upper limb recovery of people with central injuries: a systematic review with meta-analysis

The systematic review requires a strict methodology and the best practice is to create and register a protocol, since the systematic review with design and compliance with the protocol has better quality and has less risk for reporting bias. Protocols include the research question, team members, search strategy, databases to search, inclusion and exclusion criteria, quality assessment tool, data extraction template, software, and more. Thereby, the systematic review developed by the CAMIN team “Effectiveness of hybrid robotic rehabilitation system on upper limb recovery of people with central injuries: a systematic review with meta-analysis” created a protocol and published it in the International Prospective Register of Systematic Reviews - PROSPERO an international database of prospectively registered systematic reviews in health and social care. PROSPERO aims to provide a comprehensive listing of systematic reviews registered at inception, to help to avoid unplanned duplication, and to provide transparency in the review process to minimize reporting bias by enabling comparison of the completed review with what was planned in the protocol. Registration in PROSPERO involves the submission and publication of key information about the design and conduct of a systematic review. Key features from the review protocol are recorded and maintained as a permanent record in PROSPERO and records are published on an open-access electronic database. This online database is produced by Centre for Reviews and Dissemination (CRD) at the University of York in England and funded by the National Institute for Health Research (NIHR).Previous studies indicate that hybrid robotic rehabilitation systems (HRRS) may be more effective in improving motor control and functional skills compared to robotic therapy alone in patients with hemiparesis after chronic stroke and compared to traditional physical therapy in individuals with acute stroke. However, although studies prove the potential benefit of this technology, few randomized controlled trials have been conducted so far and no systematic literature review has been carried out. Systematic reviews are necessary because it is the most appropriate and current method for summarizing and synthesizing evidences about the effectiveness and effects of interventions. Therefore, this project investigates systematically the effects of HRRS on central injuries upper limb recovery based on each of the International Classification of Functioning, Disability and Health (ICF) domains. This study contributes to the development of new hybrid neuroprostheses that are proven to be effective for upper limb rehabilitation.This systematic review is done with the participation of physicians, occupational therapists and engineers
