“…(Table 2) After calculating the annual mean serum ferritin, a state of depletion of this marker was observed in only 1.96% (n=1) of the players, which may be related to the training load, because as the load increases, there is a tendency for levels of ferritin, which is considered a marker of training tolerance in endurance athletes and is related to gradual depletion of iron stores, to drop. 21 Among the players assessed in this study, 4.9% had high TIBC values in comparison to the reference range, which may be associated with the iron depletion that occurred in some of the athletes, since when there is a drop in iron and transferrin saturation levels, the TIBC values increase. 21 An important result was found in this study in which BF% above 16% was correlated with iron depletion (p=0.01).…”

This result can be explained by the need to decrease the body fat percentage and the implementation of a restrictive and inadequate diet, which, together with strenuous training and competitions, contribute to nutrient deficiency.…”

Introduction: Soccer players may experience hematological changes that could be detrimental to their health status. In addition, inadequate body composition may impair performance. Objective: To assess body composition and hematological changes over a year in soccer players. Methods: A retrospective observational study was conducted. Age, weight, height, body composition, blood count, serum iron, serum ferritin, serum transferrin and total iron binding capacity data were collected from the athletes’ medical records in the months of January, May and August of 2015 and January of 2016. Body mass index was also calculated. For the statistical analyses, the Anova and post-hoc Tukey’s post-hoc tests were used for the quantitative variables and the Chi-square test for the qualitative variables. The significance level adopted was p<0.05. Results: Data were evaluated for 51 athletes with a mean age of 23.53 ± 3.11 years, 77.10 ± 6.56 kg, 1.80 ± 0.07 and 15.6 ± 2.89% body fat (BF). We observed significant (p<0.05) changes in mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, cell size and eosinophils during the period evaluated. Among the athletes, 21.6% had decreased hematocrit levels and 3.9% had hemoglobin levels below the reference range. A BF% greater than 16% was significantly related to serum iron depletion (p = 0.01). Conclusion: Small significant hematological changes during the competitive year were observed, but without significant changes in body composition. Level of Evidence III; Study of nonconsecutive patients; without consistently applied reference ‘‘gold’’ standard.

“…Quando as reservas de ferro estão baixas, qualquer declínio adicional no ferro corporal é acompanhado por uma redução na concentração do ferro sérico. Devido às alterações diárias do nível de ferro sérico (21), este teste isoladamente apresenta valor limitado, devendo ser analisado em combinação com a saturação da transferrina e a ferritina sérica (22).…”

Iron deficiency anemia may impair learning ability in children aged 02 to 06 years. This disease may produce behavioral effects such as lack of attention, fatigue and tiredness that can lead to poor school performance. The aim of this study was to determine the number of children 02 to 06 years who performed the measurements of ferritin, serum iron and hemogram in a clinical laboratory in Belo Horizonte/MG, in the first half 2011, seeking to evaluate the results of these examinations and to establish the prevalence of iron deficiency in studied subjects. We conducted a descriptive cross-sectional observational study. Through software-BI SADIG, used for data management of the clinical laboratory, we selected 363 children from 02 to 06 years who performed the measurements of ferritin, serum iron and hemogram during the period from January first to July thirty-one, two thousand and eleven. The male children had plasma ferritin levels significantly lower when compared with female children (p<0.05). There were no significant differences between participants of both sexes for serum iron and hemoglobin. Nine children (2.5%) had anemia (Hb ≤ 11.0 g/dL and ferritin ≤ 12 ng/mL). There was a low prevalence of iron deficiency anemia in children. The most important finding of this study was nearly five times greater risk of developing iron deficiency anemia in children who had plasma ferritin levels below or equal to 12 ng/mL, suggesting that this may be considered the best cutoff point for the population studied.KEY WORDS: iron deficiency anemia; children; ferritin. RESUMOEm crianças pré-escolares a anemia ferropriva pode comprometer a capacidade de aprendizagem, além de produzir efeitos comportamentais como a falta de atenção, fadiga e cansaço que podem levar ao baixo rendimento escolar. O objetivo deste estudo foi verificar o número de crianças de 02 a 06 anos que realizaram as dosagens de ferritina, ferro sérico e hemograma, com suspeita de anemia ferropriva, num laboratório clínico, no primeiro semestre de 2011, buscando avaliar os resultados dos referidos exames e estabelecer a prevalência de anemia ferropriva nos indivíduos estudados. Foi conduzido um estudo observacional descritivo do tipo transversal. Através do software SADIG-BI, utilizado para gerenciamento de dados, foram selecionadas 363 crianças de 02 a 06 anos que realizaram os exames ferritina, ferro sérico e hemograma no período de 01/01/2011 a 31/07/2011. As crianças do sexo masculino apresentaram níveis plasmáticos de ferritina significativamente mais baixos quando comparadas com as crianças do sexo feminino (p<0,05). Com relação aos parâmetros ferro sérico e hemoglobina, não foram observadas diferenças significativas entre os participantes dos dois sexos. Das 363 crianças estudadas, 9 (2,5%) apresentavam anemia ferropriva (Hb ≤11,0 g/dL e Ferritina ≤12 ng/mL). Foi observada uma baixa prevalência de anemia ferropriva nas crianças estudadas. O achado mais importante deste estudo foi o risco quase cinco vezes maior do desenvolvimento de anemia ferrop...

“…A avaliação do ferro sérico determina a concentração de ferro circulante no sangue (GROTTO, 2010). O ferro atua nas funções do metabolismo humano, transportando e armazenando oxigênio, e nas reações metabólicas, sendo estocado como ferritina e quando os valores de ferritina estão baixos indicam depleção do estoque de ferro devido à má absorção ou ingestão.…”

RESUMO:Os métodos cirúrgicos estão cada vez mais avançados, considerados eficazes para pacientes com obesidade mórbida. A primeira cirurgia bariátrica a ser realizada para o tratamento de obesidade foi realizada em 1954, por Kremen. Pacientes submetidos a cirurgia bariátrica são acompanhados por equipe multidisciplinar para auxiliar e motivar o tratamento bariátrico. O presente artigo teve como objetivo analisar a importância do papel do farmacêutico no tratamento pré e pós-operatório de pacientes, as formas farmacêuticas utilizadas, principais deficiências nutricionais, e relatos dos pacientes juntamente com suas expectativas e dificuldades. A presente pesquisa é classificada como exploratória, do tipo qualitativa e quantitativa, realizada através de questionário entregue a vinte pacientes de ambos os sexos, entre os meses de fevereiro a maio de 2017, em uma rede de farmácia de Telêmaco Borba-PR. Os dados obtidos foram analisados e agrupados no Microsoft Excel®. Todos os pacientes estavam com o IMC elevado, principal critério para intervenção cirúrgica. As principais técnicas em cirurgia bariátrica foram bypass gástrica em Y de Roux e sleeve. A cirurgia bariátrica tem apresentado grande melhora na obesidade e principalmente na autoestima de pacientes, mas ainda existem dificuldades. O farmacêutico é o profissional habilitado e capacitado para esclarecer qualquer dúvida em relação aos medicamentos, seus efeitos colaterais e demais orientações sobre a cirurgia, devendo estar sempre presente no pré e pós-operatório de pacientes submetidos à cirurgia bariátrica. Palavras-chave: Obesidade; cirurgia bariátrica; farmacêutico. ABSTRACT:Surgical methods are increasingly advanced, considered effective for patients with morbid obesity. The first bariatric surgery to be performed for the treatment of obesity was performed in 1954, by Kremen. Patients submitted bariatric surgery are accompanied by a multidisciplinary team to assist and motivate bariatric treatment. This article aimed to analyze the importance of the role of the pharmacist in the pre and postoperative treatment of patients, the pharmaceutical forms used, the main nutritional deficiencies, and patient reports together with their expectations and difficulties. The present research is classified as exploratory, of the qualitative and quantitative type, performed through a questionnaire delivered to twenty patients of both sexes, between the months of February to May 2017, in a pharmacy network of Telemaco Borba-PR. The obtained data were analyzed and grouped
