Blend of secondary metabolites from mesquite to improve nutrient digestibility, microbial protein, efficient use of nitrogen, ruminal parameters, and blood metabolites in sheep.

Although chemical additives are able to improve the efficiency of ruminal fermentation, they can leave residues in the meat. However, a blend of secondary metabolites can improve ruminal fermentation without harming the population welfare. Five levels (0.0, 1.5, 3.0, 4.5, and 6.0 g/day) of a blend of secondary metabolites from mesquite extract in sheep feed to promote increases in the nutritional value, ruminal parameters, nitrogen (N) use efficiency, microbial protein (MP) synthesis, and blood metabolites. Ten intact male Santa Inês sheep with average body weight of 55 ± 9.81 kg were used in a 5 × 5 Latin square design, replicated twice. There was a quadratic response of the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), and total digestible nutrients (TDN). Microbial protein concentrations, MP synthesis efficiency, propionic acid levels, and acetic/propionic acid ratio also showed a quadratic response. The blend promoted a quadratic effect on plasma glucose and lactate levels. On the other hand, it decreased the concentrations of ammoniacal nitrogen, plasma urea, and plasma cholesterol. It is recommended to supply a blend of secondary metabolites at 3.43 g/day.

General aspects of the COVID-19 pandemic / Aspectos gerais da pandemia de COVID-19

Abstract Objectives: to review the available literature on the general aspects of SARS-CoV-2 infec-tion. Methods: this is a narrative literature review carried out from March to September 2020. Results: COVID-19 caused by the new coronavirus or SARS-CoV-2, grows with devas-tating effects worldwide. The literature describes epidemiological data and mortality risk groups of the disease, which presents a high rate of transmission. Prevention is the most effective way to fight the disease, persisting the absence of strong evidence on the treatment. Vaccines are not yet available. Dexamethasone is effective in reducing mortality in severe forms. Conclusions: despite great efforts, as the number of confirmed cases increases, evidence on transmission, incidence, disease progression, lethality, effects and outcomes remain limited and without any high levels of evidence. Studies are still necessary for all aspects of the disease.

Resumo Objetivos: revisar a literatura disponível sobre os aspectos gerais dainfecção por SARS-CoV-2. Métodos: trata-se de uma revisão narrativa de literatura realizada nos meses de março asetembro de 2020. Resultados: a COVID-19, causada pelo novo coronavírus ou SARS-CoV-2, cresce com efeitos devastadores em todo o mundo. A literetura descreve dados epidemiológicos e sobre grupos de riscos para mortalidade da doença, a qual apresenta uma alta velocidade de trans-missão. A prevenção é a forma mais eficaz de combate à doença, persistindo ausências de fortes evidências sobre o tratamento. Vacinas ainda não estão disponíveis A dexametasona é efetiva para redução da mortalidade nas formas graves. Conclusão: apesar dos grandes esforços, à medida que o número de casos confirmados aumenta, evidências sobre transmissão, incidência, evolução da doença, letalidade, efeitos e os desfechos permanecem limitados e sem grandes níveis de evidência. Estudos ainda são necessários sobre todos os aspectos da doença.

COVID-19 and Pregnancy / COVID-19 e Gravidez

Abstract Objectives: reviewing the available literature on COVID-19 infection and the maternal and perinatal outcomes. Methods: this is a narrative review of the literature carried out from March to September 2020, usingthe MESH: coronavirus, Covid 19, SARS-CoV-2, pregnancy, gravidity, pregnancy complications and pregnancy complications infectius. All study designs, reviews, recommendations and technical notes were included, without distinction of language and that would bring the approach of the new coronavirus in the gestational and perinatal scenario. Results: the COVID-19 pandemic has had devastating effects, affecting millions of people and claiming almost a million lives worldwide. Initially, pregnant women were not seen as a risk group for the disease, however as the proportion of women affected during the pregnancy-puerperal cycle increased, several studies were published showing an increased risk of complications. Brazilian studies have also warned of a high number of maternal deaths, associated with the presence of comorbidities but, above all, with the social determinants of the disease and serious failures in care. Conclusion: the need for new studies with an adequate research design was observed, as many studies are only letters or small series of cases, in addition expert recommendations, without the necessary scientific rigor.

Resumo Objetivos: revisar a literatura disponível sobre a COVID-19 e seus aspectos maternos e perinatais. Métodos: urna revisão narrativa de literatura foi realizada nos meses de março a setembro de 2020, utilizando os descritores, coronavirus, Covid 19, SARS-CoV-2, pregnancy, gravidity, pregnancy complications e pregnancy complications infectius. Foram incluidos todos os desenhos de estudo, revisões, recomendações e notas técnicas, sem distinção de idioma e que trouxessem a abordagem do novo coronavírus no cenárlo gestacional e perinatal. Resultados: a pandemia de COVID-19 vem apresentando efeitos devastadores, acometendo milhões depessoas e ceifando quase um milhão de vidas em todo o mundo. Inicialmente as gestantes não er am vistas como grupo de risco para a doença, porém na medida em que aumentou a proporção de mulheres acometidas durante o ciclo gravídico-puerperal diversos estudos foram publicados demostrando risco aumentado de complicações. Estudos brasileiros também alertaram para um número elevado de mortes maternas, associados à presença de comorbidades, mas, sobretudo, aos determinantes sociais da doença e a falhas graves da assistência. Conclusão: observou-se a necessidade de novos estudos com adequado delineamento de pesquisa, pois muitos estudos são apenas cartas ou pequenas séries de casos, além de recomendações de especialistas, sem o rigor científico necessário.

Perineal Pain Management with Cryotherapy after Vaginal Delivery: A Randomized Clinical Trial.

Introduction Systematic reviews that evaluate the perineal cryotherapy to reduce pain in the vaginal postpartum are inconclusive. Purpose To evaluate clinical effectiveness of cryotherapy in the management of humanized postpartum perineal pain and vaginal edema. Methods A double-bind randomized controlled clinical trial (UTN number: U1111-1131-8433) was conducted in a hospital in Northeastern, Brazil. Women were included following humanized childbirth. All had vaginal deliveries of a single, full-term pregnancy with cephalic presentation. Exclusion criteria included previous perineal lesion, episiotomy during the current delivery, instrumental delivery, uterine curettage and postpartum hemorrhage. In the experimental group, an ice pack was applied six times on the perineum for 20 minutes, reducing the temperature between 10 and 15 ° C, then 60 minutes without exposure to cold. In the non-cryotherapy, a water bag unable to reduce the temperature to this extent was used, compliance with the same application protocol of the first group. Perineal temperature was monitored at zero, 10 and 20 minutes for application in both groups. Evaluations were made immediately before and after the applications and 24 hours after delivery spontaneous, to determine the association between variables. Results A total of 80 women were included in the study, 40 in each group. There was no significant difference in scores of perineal pain and edema between the groups with or without cryotherapy until 24 hours after childbirth. There was no difference between groups when accomplished repeated measures analysis over the 24 hours after delivery, considering the median perineal pain (p = 0.3) and edema (p = 0.9). Perineal cryotherapy did not influence the amount of analgesics used (p = 0.07) and no adverse effect was registered. Conclusion The use of cryotherapy following normal vaginal delivery within the concept of humanized minimally interventionist childbirth had no effect on perineal pain and edema, since it was already substantially lower, nor the need for pain medicaments.

Resumo Introdução Revisões sistemáticas que avaliam a crioterapia perineal para redução da dor no pós-parto por via vaginal são inconclusivas. Objetivo Avaliar a efetividade clínica da crioterapia para controlar a dor e o edema perineais após parto vaginal humanizado. Métodos Ensaio clínico (n° UTN: U1111-1131-8433) randomizado controlado duplocego, realizado em uma maternidade no Nordeste do Brasil. Incluíram-se mulheres após parto vaginal humanizado, de gestação única, cefálica, a termo, e foram excluídas aquelas com lesão perineal prévia, episiotomia no parto atual, parto instrumental e hemorragia perineal ativa. O grupo experimental foi submetido a seis aplicações de bolsa de gelo triturado na região do períneo, por 20minutos, reduzindo a temperatura entre 10 e 15°C, com 60 minutos entre as aplicações. O grupo sem crioterapia recebeu uma bolsa de água, que não reduzia a temperatura a esse nível, respeitando o mesmo protocolo de aplicação do primeiro grupo. Amonitorização da temperatura perineal foi realizada nos minutos zero, 10 e 20 de aplicação, emambos os grupos. Para determinar a associação entre as variáveis, foramrealizadas avaliações imediatamente antes e após as aplicações e 24 horas após o parto. Resultados Foram incluídas 80 puérperas no estudo, sendo 40 em cada grupo. Não houve diferença significativa para os escores de dor e edema perineais entre os grupos comou sem crioterapia até 24 horas após o parto. Não houve diferença entre os grupos quando realizada análise de medidas repetidas em todas as avaliações, considerando a mediana dos escores de dor (p = 0,3) e edema (p = 0,9) perineais. A crioterapia perineal não influenciou na quantidade de analgésicos utilizados (p = 0,07) e nenhum efeito adverso foi registrado. Conclusões A utilização da crioterapia após parto vaginal humanizado, minimamente intervencionista, nãomodifica escores de dor e edema perineais, por já serem, substancialmente, baixos, tampouco altera a necessidade de medicamentos analgésicos.
