Comparing the effect of zinc gluconate and placebo in the treatment of tachypnea, dyspnea and fever in children aged 2 to 23 months with acute bronchiolitis

Background:Acute viral bronchiolitis is the most common infection of the lower respiratory tract in infants under 2 years and is one of the reasons for their admission all around the world. The aim of this study was comparing the effect of zinc gluconate and placebo in the treatment of tachypnea, dyspnea and fever in children aged 2to 23 months with acute bronchiolitis.Methods:This randomized clinical trial study has been done on 100 infants aged 2to 32 months with the diagnosis of bronchiolitis who divided in two groups. 50 patients received zinc gluconate and 50 patients received placebo. The symptoms and sign of the disease at baseline and then at 24, 72, and 7 days after starting treatment and duration of hospitalization were compared between the two groups.Results:The treatment and placebo groups were similar in respect to mean age and gender distribution. Two groups were similar in terms of clinical symptoms and signs at the time of admission. Bronchiolitis recovery was better in the treatment group than in the placebo group. This positive effect was statistically significant for vising (p=0.023) and rhinorrhea (p=0.027) at 72 hours after starting treatment. The mean duration of hospitalization was significantly less in the treatment group than in the placebo group (4.14±1.21 versus 4.64±1.2 days; p=0.016). Conclusions: Results showed that the use of zinc gluconate as a zinc supplement in infants with acute bronchiolitis could improve their clinical symptoms and signs and decrease the duration of hospitalization

Effect of piglet castration with nonsurgical sterilant on the zootechnical performance and pork carcass quality / Efeito da castração de leitões com esterilizante não cirúrgico no desempenho zootécnico e na qualidade da carcaça suína

A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per animal and feed conversion. The slaughter of the animals and the assessment of the carcass and meat quality and hormone levels were carried out in a slaughterhouse and the municipality of Campinas (SP). The study demonstrated that the use of NSS was a viable alternative in relation to the zootechnical performance and the carcass quality. In relation to the meat quality there was no significant difference in the majority of the assessed parameters.(AU)

Foi utilizado esterilizante não cirúrgico (ENC) com o objetivo de se avaliar o desempenho zootécnico e a qualidade de carcaça, de carne e de níveis hormonais. Foram selecionados 90 leitões machos de peso entre 1,5kg e 2,0kg ao nascimento. O grupo controle foi constituído por 45 machos castrados pelo método cirúrgico convencional, ao sétimo dia de idade, e o grupo tratado foi constituído por 45 machos castrados com ENC (princípio ativo de gluconato de zinco na concentração de 26,2mg/mL associado ao dimetil sulfóxido a 0,5%), com primeira dose de aplicação ao sétimo dia de idade e a segunda dose ao 14° dia de idade. As avaliações consistiram de: ganho de peso nos períodos por animal e conversão alimentar. O abate dos animais e a avaliação da carne e de níveis hormonais foram realizados em um frigorífico, na cidade de Campinas (SP). O uso de ENC foi uma alternativa viável em relação ao desempenho zootécnico e à qualidade da carcaça. Em relação à qualidade da carne, não houve diferença significativa na maioria dos parâmetros avaliados.(AU)

Methods A random, double-blind and placebo-controlled study was conducted in a total of 901 healthy male recruits, who were randomized into 2 groups, experiment group and control group, by using a random-number table. The experiment group, consisted of 447 recruits, was given zinc gluconate nasal spray, and the control group, consisted of 454 recruits, with placebo for one month. During the course of the experiment, 61 in trial group and 67 in control group were eliminated. The incidence of upper respiratory infection, influenza-like illness, and the incidence of all the symptoms were documented after treatment for one month. Results Seven hundred and seventy-three recruits completed the schedule finally up to standard, among them 386 recruits were in experiment group and 387 in placebo group. The incidence of upper respiratory infection and influenza-like illness were lower in experiment group (26.94% and 0.26%, respectively) than in control group (34.37% and 2.06%, respectively; ?2=5.010 for upper respiratory infection, P
