The role of body composition on cardio-respiratory fitness in futsal competitive athletes

Futsal is an intermittent high intensity sport which has become popular worldwide. Body composition and physical fitness have been studied in different sports disciplines. However, little is known regarding body composition and cardio-respiratory performance in competitive futsal players. Body composition parameters were analyzed by electrical impedance body composition analyzer in 31 competitive male futsal players. All participants performed spirometry, handgrip strength and cardiopulmonary exercise testing. Significant correlations were observed between muscle mass and spirometry parameters and peak VO2 (p≤0.05). Fat mass resulted inversely correlated with peak VO2% predicted and hand grip strength (p≤0.05). Regression analysis showed that muscle mass significantly predicts respiratory parameters (p<0.01) and reduced fat mass is associated with increased peak VO2 % predicted and handgrip strength (p<0.01). In futsal competitive athletes increased muscle mass is associated with higher spirometry parameters and fat mass is inversely associated with lower cardiorespiratory fitness

Bagaço de mandioca com ou sem complexo enzimático em dietas de frangos de corte

The present work was conducted to evaluate the use of cassava bagasse (BM) in rations with enzyme complex (CE) as supplement for broilers in two phases. Two experiments were conducted to assess the weight gain (GP), feed intake (CR) and feed conversion (CA) in the phases 1-21 and 22-40 days of age, of broilers receiving diets containing 0 and 20 % of BM and, with or without CE. The experiments were conducted in a completely randomized block design with 8 replicates and 20 broiler per experimental unit using a 2x2 factorial arrangement (0 and 20 % of BM, with or without CE). There was no interaction between treatments, inclusion of BM and CE. The inclusion of BM decreased CR and GP in both phases. Whereas the inclusion of CE improved GP and CA at the initial stage did not affect the performance at 22-40 days of age, the cost of feed per kilogram of weight gain was lower and the rates of economic efficiency and cost for both phases was better in animals subjected to diets with 0 % of cassava bagasse inclusion with the enzymatic complex.Objetivou-se avaliar a utilização de bagaço de mandioca (BM) em rações suplementadas com complexo enzimático (CE) para frangos de corte em duas fases. Foram avaliados o ganho de peso (GP), consumo de ração (CR) e conversão alimen- tar (CA) de frangos de corte nas fases de 1 a 21 e 22 a 40 dias, alimentados com rações contendo 0 e 20 % de inclusão de BM com e sem adição de CE. Os experimentos foram realizados num delineamento experimental em blocos casualizados com 4 tratamentos utilizando um arranjo fatorial 2x2 (0 e 20 % de BM, com e sem CE) com 8 repetições e 20 aves por unidade experimental. Não foi observada interação entre os tratamentos, inclusão de BM e CE. A inclusão do BM diminuiu o CR e o GP em ambas as fases de criação. Enquanto que a inclusão do CE melhorou o GP e a CA das aves na fase inicial, não afetando o desempenho na fase de 22 a 40 dias de idade, já menor custo de ração por quilograma de ganho de peso e os melhores índices de eficiência econômica e de custo para ambas as fases foi encontrado para os animais que foram submetidos a rações com 0 % de inclusão de bagaço de mandioca com adição de complexo enzimático

A Cross-Sectional Study of Untoward Reactions Following Homologous and Heterologous COVID-19 Booster Immunizations in Recipients Seventeen Years of Age and Older

A booster dose after primary COVID-19 vaccination series was considered crucial after the emergence of the B.1.617.2 (Delta) and B.1.1.529 (Omicron) variants. Active surveillance was used to investigate reporting of adverse events post-booster dose of either of the licensed mRNA Comirnaty (Pfizer/BioNTech) or Spikevax (Moderna) vaccines in adult (17 years and older) recipients in central Italy. Eligible participants were enrolled and interviewed via phone using a structured questionnaire. Primary outcomes related to the occurrence of adverse events post-booster were stratified by vaccine, and frequency of local/systemic, mild/moderate/severe events. Of a total of 622 participants interviewed, 554 (89.1%) reported at least one adverse event (88.2% and 92.9% after the Comirnaty or Spikevax vaccine, respectively): 63.4% were female, and 78.5% aged 17 to 64 years, regardless of vaccine. 87.7% and 68.2% of all recipients described at least one local or systemic reaction, respectively: 97.3, 38.6 and 4.7% reported mild, moderate, or severe events, respectively. The most frequent adverse reactions were pain, redness, or swelling at the injection site and fatigue, while malaise and fever significantly occurred after the Comirnaty, and vomiting after the Spikevax booster. Compared to the primary vaccination, lymphadenopathy was more common after the booster (p < 0.001), especially after Comirnaty vaccine. The study findings revealed no serious or unexpected adverse events, and are in agreement with data available on booster dose for both mRNA vaccines. The transient, mild to moderate, and common to very common side reactions reported should be used to reassure potential recipients of the lack of safety concerns

Níveis de inclusão da torta de babaçu em rações de frangos de corte na fase inicial Levels of inclusion of babassu coconut in diets for broiler chickens

Objetivou-se avaliar os níveis de inclusão da torta de babaçu (0, 4, 8 e 12%) na alimentação de frangos de corte no período de um a 21 dias de idade. Utilizou-se 200 pintos de corte da linhagem Hubbard, distribuídos em um delineamento experimental inteiramente casualizado, com quatro tratamentos e cinco repetições de 10 aves por unidade experimental. Os tratamentos consistiram de rações experimentais que continham níveis crescentes de inclusão da torta de babaçu (0, 4, 8, 12%), formuladas para serem isoenergéticas e isoprotéicas. As variáveis de desempenho avaliadas foram o consumo de ração, ganho de peso e conversão alimentar. Para a determinação de energia metabolizável aparente corrigida, retenção diária de energia, matéria seca e nitrogênio das rações experimentais realizou-se coleta de excretas de cada repetição por três dias consecutivos, e estas foram analisadas juntamente com as rações quanto ao teor de matéria seca, energia bruta e nitrogênio. A inclusão da torta de babaçu não afetou nenhuma das variáveis de desempenho avaliadas. Da mesma forma não foi observado efeito dos níveis de inclusão da torta de babaçu sobre a energia metabolizável corrigida e sobre o coeficiente de retenção de energia bruta. Concluiu-se que a torta de babaçu pode ser utilizada como ingrediente em rações de frangos de corte de um a 21 dias até o nível de 12%.<br>The objective of this study was to evaluate the levels of inclusion of babassu coconut (0, 4, 8 and 12%) in diets for broiler chickens from 1 to 21 days old. 200 Hubbard chicks were distributed in a completely randomized design with four treatments and five replications, being each experimental unit composed of 10 birds. The treatments consisted in experimental diets containing increasing levels of inclusion of babassu coconut (0, 4, 8 and 12%), formulated to contain the same nutritional level. The performance of variables evaluated were feed intake, weight gain and feed conversion. The apparent metabolizable energy, diary retention of gross energy, dry matter and nitrogen of experimental diets was determined by total collection of excreta for three consecutive days, which are analyzed together with the feed for dry matter, gross energy and nitrogen contents. The inclusion of the babassu not affected any of the evaluated variables. Likewise, there was no effect of inclusion levels of babassu coconut on the apparent metabolizable energy and the diary of retention of gross energy. On this basis, the babassu coconut can be used as an ingredient in diets of broilers from 1 to 21 days until the level of 12%

Técnicas de avaliação dos valores energéticos e dos coeficientes de digestibilidade de alguns alimentos para emas (Rhea americana) em crescimento

Avaliaram-se os valores de energia metabolizável aparente e aparente corrigida (EMA e EMAn, respectivamente), os coeficientes de metabolização da energia bruta (CMEB e CMEBn) e da digestibilidade da MS e MO (CDAMS e CDAMO) de alguns alimentos para emas (Rhea americana) de sete meses de idade, utilizando-se as técnicas de coleta total de excretas e do óxido de cromo como indicador. Utilizou-se o delineamento experimental inteiramente ao acaso, em esquema de parcelas subdivididas, com seis tratamentos, cada um com três repetições. O experimento foi realizado três vezes, seqüencialmente. Os valores dos CDAMS, CDAMO, EMA, EMAn, CMEB e CMEBn dos alimentos, determinados por meio da técnica de coleta total de excretas, foram, de modo geral, superiores aos determinados pela técnica do óxido de cromo. A técnica do óxido de cromo mostrou-se inadequada para determinar os CDAMS, CDAMO, EMA, EMAn, CMEB e CMEBn dos alimentos para emas em comparação à técnica de coleta total de excretas. Recomenda-se a realização de ensaios similares envolvendo outras técnicas indiretas para estimar parâmetros de digestibilidade nesta espécie

Safety of mRNA BNT162b2 COVID-19 (Pfizer-BioNtech) vaccine in children aged 5-11 years: Results from an active pharmacovigilance study in central Italy

This survey investigated on adverse events after vaccination with mRNA BNT162b2 (Comirnaty, Pfizer-BioNTech) vaccine in children aged 5–11 years in central Italy through active surveillance reporting. During December 2021–January 2022, parents of children who undergone vaccination were interviewed using a structured questionnaire. 197 out of 208 contacted parents participated (94.7% response rate), of whom 166 (84.3%) had one child. Of the 229 children, the mean age was 8.9 years, 50.7% were female. 193 (84.3%) had at least one adverse event after the first dose (mean age 9.1 years; 54.4% female), and 146 (73.4%) of 199 after the second (mean age 8.9 years; 54.8% female), which was not administered to 30 children due to previous COVID-19 history. Local symptoms after the first and second dose occurred in 183 (94.8%) and 141 (96.6%) recipients (p = .435), respectively, while systemic reactions in 62 (32.1%) and 34 (23.3%) (p = .074). Mild events were reported by 81.7% and 69.8% children after the first and second dose, followed by moderate (3.9% and 10.6%) and severe (1.3% and 0.5%). After each dose, injection site reactions (79.5% and 68.8%) were the most frequent, followed by headache (13.1%) and lymphadenopathy (8.5%) after the first and second dose, respectively. The adverse events were reported to pediatricians only for 5.7% and 3.9% of children and treated for 17.6% and 15.8%. This is the first report about safety profile through active surveillance of mRNA BNT162b2 among children in Italy, revealing temporary and mild-to-moderate symptoms with no serious events after each vaccine dose

A SARS-CoV-2 Outbreak Among Nursing Home Residents Vaccinated with a Booster Dose of mRNA COVID-19 Vaccine

This study describes a SARS-CoV-2 outbreak caused by the Delta (B.1.617.2) variant in a nursing home in Central Italy during October–November 2021. Trained interviewers collected data from residents, staff, and administration officers with an agreed informed consent procedure. Thirty-two (44.5%) out of 72 residents (median age 89 years) and six (26.1%) of 23 healthcare workers were found to be infected with SARS-CoV-2. Infections occurred more often among residents with a higher index of independence in daily living activities, suggesting an increased risk for those with more interactions. Twenty-five infected residents (78.1%) received the booster dose of mRNA anti-COVID-19 vaccine > 7 days before SARS-CoV-2 onset. Half of the infected residents had mild symptoms, and only three required hospitalisation, one of whom died from COVID-19 complications. The study underlines the effectiveness of a booster dose in providing a high protection against severe disease and hospitalisation even among vulnerable individuals infected with the Delta variant of concern
