Comportamentos de risco para os transtornos alimentares em jovens atletas de voleibol: o estilo de liderança do treinador é um fator interveniente?
The aim of this study was to analyze the influence of coach’s leadership style on eating disorders (ED) in female volleyball athletes. This is a prospective study with 73 participants of sub-17 state of Pernambuco Championship. The Eating Attitudes Test was applied to evaluate ED. The perception of the coach’s leadership style was evaluated with Leader Sport Scale subscales. Triceps and subscapular skinfolds were measured to estimate body fat percentage. The findings showed no influence of “Training-Instruction” on ED (F(3, 70)=45.02; R2=0.12; p=0.34). The “Social Support” subscale showed statically significant influence on ED (F(4, 69)=59.77; R2=-0.16; p=0.02). However, the results indicated no statically significant relationship of “Reforce” subscale with ED (F(5, 68)=52.40; R2=0.13; p=0.17). The “Democratic” subscale so showed no influence on ED F(6, 67)=49.08; R2=0.10; p=0.21). Finally, the “Autocratic” subscale showed influence on ED (F(7, 66)=67.23; R2=0.18; p=0.01). We concluded that the coach’s leadership style (social support and autocratic) influenced the adoption of DEB in young female volleyball athletes.O objetivo da investigação foi analisar a influência do estilo de liderança do treinador sobre os comportamentos de risco para os transtornos alimentares (CRTA) em atletas de voleibol do sexo feminino. Trata-se de uma investigação com delineamento prospectivo (follow-up de 3 meses) desenvolvida com 73 atletas participantes do campeonato Pernambucano da categoria sub-17. Para avaliar os CRTA foi aplicado o Eating Attitudes Test. A fim de se avaliar a percepção do estilo de liderança do treinador, foram utilizadas as subescalas da versão percepção-atleta da Escala de Liderança no Desporto. Foram aferidas as dobras cutâneas triciptal e subescapular para a estimativa do percentual de gordura corporal. Os achados não revelaram influência da subescala “Treino-Instrução” sobre os CRTA (F(3, 70)=45,02; R2=0,12; p=0,34). A subescala “Suporte Social” demonstrou influência estatisticamente significante nos CRTA (F(4, 69)=59,77; R2=-0,16; p=0,02). Todavia, os resultados não indicaram relação estatisticamente significante da subescala “Reforço” com os CRTA (F(5, 68)=52,40; R2=0,13; p=0,17). Do mesmo modo, a subescala “Democrático” também não demonstrou influência sobre os CRTA (F(6, 67)=49,08; R2=0,10; p=0,21). Por fim, a subescala “Autrocrático” apontou influência sobre os CRTA (F(7, 66)=67,23; R2=0,18; p=0,01). Concluiu-se que o estilo de liderança do treinador (suporte social e autocrático) influenciou na adoção de CRTA em jovens atletas de voleibol do sexo feminino

Molecular and Biotechnological Approaches in the Diagnosis of Leprosy
Leprosy is a worldwide health problem, which needs the development of new and innovative strategies to be controlled. Early diagnosis of leprosy is an important contribution to reducing the incidence of the disease; thus, the development of biotechnology platforms, which include the mapping of antigens with potential to be used in immunodiagnostic and molecular methods for the detection of Mycobacterium leprae, is an important tool to confirm the clinical diagnostic. Molecular biology and biotechnological methods have been used to assist in the diagnosis of this disease, each one with its advantages and drawbacks. Enzyme-linked immunosorbent assay (ELISA) is the used method for leprosy diagnosis, and it allows the detection of infection-related antigens. Alternatively, due to their versatility to perform the same functions as the protein and non-protein natural antigens, mimetic peptides are considered an important tool. On the other hand, lateral flow assay (LFA) and optical and electrochemical biosensors are rapid and portable methods, capable of performing diagnosis in the field without sample preparation. This chapter presents such techniques, their uses in the diagnosis and detection of M. leprae, as well as the potential for the development of new techniques and strategies that can help to control and understand mycobacteriosis
Mixed-Thickness Tunnel Access (MiTT) through a linear vertical mucosal incision for a minimally invasive approach for root coverage procedures in anterior and posterior sites: technical description and case series with 1-year follow-up
Purpose: The goal of this article was to introduce a new root coverage (RC) technique, the mixed-thickness tunnel access (MiTT) technique, which approaches a full-split design and intends to augment soft tissues coronal to the gingival margin. It was shown step-by-step, and the results were presented in a case series. Methods: Healthy individuals (non-diabetics) and non-smokers with gingival recession (GR) type 1 or 2 (RT1 or RT2) were included. After evaluation, prophylaxis was performed 14 days before the surgical procedure. During the surgical appointment, one or two vertical incision(s) on the mucosa (around 1–2 mm apical to the MGJ), lateral to the papilla base, was/were performed after anesthesia. Initially, there was a partial incision to detach the mucosa of the muscles (split design). It was permitted (but not mandatory) to perform intrasulcular incisions. Through the vertical incision, internally, subperiosteal access from the MGJ toward the gingival margin (coronally) was performed to create a full-thickness tunnel. Then, communication from the vertical incision with the gingival sulcus and the papilla base occurred, keeping the papilla tip intact. A connective tissue graft was harvested and inserted through the linear incision or intrasulcularly. There were interrupted sutures. An adjunctive material may be applied (e.g., Endogain). The root coverage was measured using a periodontal probe and considered fully covered when the gingival margin was 1 mm coronal to the cementum–enamel junction (CEJ). Results: Nine healthy individuals (seven females and two males) aged 19 and 43 were enrolled. They were treated following the MiTT steps. Four cases had a single GR; two patients had two teeth involved; and three others had three or four GR. There were seven cases of RT1 and two RT2. All RT1 cases achieved 100% RC, while the mean RC obtained for RT2 was around 80%. Conclusion: The MiTT technique can be considered a more straightforward approach for minimally invasive surgical techniques, which is a feasible option to treat RC with a high success rate, predictability, and esthetic preservation. Therefore, there is a technical sensitivity to performing the full-split design procedure.info:eu-repo/semantics/publishedVersio
Efeito de um período de polimento na potência e capacidade anaeróbia de atletas de tae-kwon-do
The aim of the study was to analyze the effect of a tapering period on anaerobic power and capacity of tae-kwon-do athletes. Thirty-one male tae-kwon-do participants of the Brazilian Championship were selected in a non-probabilistic way. Subjects were randomly divided into two groups, namely: experimental group (EG, n = 15) and control group (CG, n = 17). Both groups followed the same training protocol up to the tapering stage. CG was submitted to training loads contained in the last two weeks of the macrocycle. Only EG was submitted to tapering. Tapering had 2 weeks duration, adopting the linear tapering method. Taekwondo Anaerobic Test was performed by athletes before the start of the season, which was named as pre-intervention, and the last week of each mesocycle [Prep I, Prep II and Tapering (only EG)]. Group vs. time effect interaction (p < 0.01) was identified for alactic anaerobic power, with an increase only in EG in tapering (p = 0.01). A significant group vs. time interaction (p <0.01) was revealed to fatigue index, improved anaerobic capacity being checked in EG only after the tapering period (p = 0.01). It was concluded that two weeks of linear type tapering optimized the anaerobic power and capacity of male tae-kwon-do athletes.O objetivo do estudo foi analisar o efeito de um período de polimento sobre a potência e capacidade anaeróbia de atletas de tae-kwon-do. Trinta e um atletas de tae-kwon-do do sexo masculino participantes do campeonato brasileiro de tae-kwon-do foram selecionados de forma não probabilística. Os atletas foram separados aleatoriamente em dois grupos, a saber: experimental (GE, n = 15) e controle (GC, n = 17). Ambos os grupos seguiram o mesmo treinamento até a fase do polimento. O GC manteve as cargas de treinamento constantes nas últimas duas semanas do macrociclo. Somente o GE realizou o polimento. O polimento teve duração de 2 semanas, adotando-se o método de polimento linear. O Taekwondo Anaerobic Test foi realizado pelos atletas antes do início da temporada, o que foi denominado como pre-intervenção, e na última semana de cada mesociclo [Preparatório I, Preparatório II e Polimento (somente para o GE)]. Foi identificado efeito de interação grupo vs. tempo (p < 0,01) para a potência anaeróbia alática, com aumento apenas no GE na fase do polimento (p = 0,01). Uma interação significante grupo vs. tempo (p < 0,01) foi revelada para o índice de fadiga, com melhoria da capacidade anaeróbia sendo verificada no GE somente após a fase de polimento (p = 0,01). Concluiu-se que duas semanas de polimento do tipo linear otimizou a potência e capacidade anaeróbia de atletas de tae-kwon-do do sexo masculino
Managing patients with dengue fever during an epidemic: the importance of a hydration tent and of a multidisciplinary approach
<p>Abstract</p> <p>Background</p> <p>Dengue fever is one of the most common tropical diseases worldwide. Early detection of the disease, followed by intravenous fluid therapy in patients with dengue hemorrhagic fever (DHF) or with warning signs of dengue has a major impact on the prognosis. The purpose of this study is to describe the care provided in a hydration tent, including early detection, treatment, and serial follow-up of patients with dengue fever.</p> <p>Findings</p> <p>The analysis included all patients treated in the hydration tent from April 8 to May 9, 2008. The tent was set up inside the premises of the 2<sup>nd </sup>Military Firemen Group, located in Meier, a neighborhood in Rio de Janeiro, Brazil. The case form data were stored in a computerized database for subsequent assessment. Patients were referred to the tent from primary care units and from secondary city and state hospitals. The routine procedure consisted of an initial screening including vital signs (temperature, blood pressure, heart rate, and respiratory rate), tourniquet test and blood sampling for complete blood count. Over a 31-day period, 3,393 case recordings were seen at the hydration tent. The mean was 109 patients per day. A total of 2,102 initial visits and 1,291 return visits were conducted. Of the patients who returned to the hydration tent for reevaluation, 850 returned once, 230 returned twice, 114 returned three times, and 97 returned four times or more. Overall, 93 (5.3%) patients with DHF seen at the tent were transferred to a tertiary hospital. There were no deaths among these patients.</p> <p>Discussion</p> <p>As the epidemics were already widespread and there were no technical conditions for routine serology, all cases of suspected dengue fever were treated as such. Implementing hydration tents decrease the number of dengue fever hospitalizations.</p
Dietary whey protein lessens several risk factors for metabolic diseases: a review
Obesity and type 2 diabetes mellitus (DM) have grown in prevalence around the world, and recently, related diseases have been considered epidemic. Given the high cost of treatment of obesity/DM-associated diseases, strategies such as dietary manipulation have been widely studied; among them, the whey protein diet has reached popularity because it has been suggested as a strategy for the prevention and treatment of obesity and DM in both humans and animals. Among its main actions, the following activities stand out: reduction of serum glucose in healthy individuals, impaired glucose tolerance in DM and obese patients; reduction in body weight; maintenance of muscle mass; increases in the release of anorectic hormones such as cholecystokinin, leptin, and glucagon like-peptide 1 (GLP-1); and a decrease in the orexigenic hormone ghrelin. Furthermore, studies have shown that whey protein can also lead to reductions in blood pressure, inflammation, and oxidative stress.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Univ Estadual Campinas UNICAMP, Dept Clin Med, BR-13083970 Campinas, SP, BrazilUniv São Paulo, Inst Ciencias Biomed, Dept Fisiol & Biofis, São Paulo, BrazilUniv Extremo Catarinense, Lab Bioquim & Fisiol Exercicio, Criciuma, SC, BrazilUniv Estadual Paulista UNESP, Dept Patol, Botucatu, SP, BrazilUniversidade Federal de São Paulo UNIFESP, Dept Fisiol, São Paulo, BrazilUniversidade Federal de São Paulo UNIFESP, Dept Psicobiol, São Paulo, BrazilUniversidade Federal de São Paulo UNIFESP, Dept Fisiol, São Paulo, BrazilUniversidade Federal de São Paulo UNIFESP, Dept Psicobiol, São Paulo, BrazilWeb of Scienc
