Mouse embryo production by superstimulation is a multifactorial process. To minimize the number of sacrificed animals and to maximize the results of the superstimulatory treatment, it should be possible to predict the risk of do not get embryos from such a treated animal. This work aimed to evaluate if the variables - hormone concentration and the timing of its administration, the copulatory plug presence and individual male used to mating – could be predictive factors on the mouse embryo production. Females were distributed in four groups (cross-over design) related to scheduled superstimulation treatment (1300h or 1700h) and eCG/hCG administered concentration (5 or 10IU). After the hCG treatment, females were put to mate. On the next morning it was verified the presence of a copulatory plug (D0.5). Embryo recovery was performed from D2.5 to D4.5 by flushing the oviducts and uterine horns. Total structures recovered (TSR) and the viable embryos (VE) were classified by its morphology. Viability rate (VR) was calculated with VE in relation to TSR (x100). Group comparison was analyzed with 5% of significance. There were no significant differences among groups, even when only main effects were analyzed (hormone concentration and timing of its administration). There was significant difference in VR from animals with or without plug and from the worst and best males used. It was concluded that neither the hormone concentration nor timing of its administration - or their association – was significant as predictive factors for the embryo production. However, the plug presence was related to higher VR.

In order to reduce the sedentarism and to improve population's health condition, many physical activity incentive programs have been stimulated. As a result, many people have adhered to street racing, but their health condition is almost always ignored. The aim of this study was to evaluate street racers' health condition, identifying the presence of cardiovascular risk factors as well as problems associated to street racing. The study case was composed by 111 racers from the town of Bauru (94 men and 17 women) aged in average 39±13 years old, who were evaluated in 4 street race competitions. The subjects answered to an anamnesis with questions about their socioeconomic status, medicine use, cardiovascular risk, physical exercise practices, and issues related to racing and injury. Weight (kg) and height (m) were measured to calculate the body mass index (BMI, kg/m²) as well as systolic and diastolic blood pressure (BP), heart rate (HR), abdominal circumference (AC), and flexibility. It could be observed that the majority of racers were Caucasian, married and belonged to social classes over C. The prevalent age was between 18 and 35 years old (42%). Among the participants, 38.7% have already undergone some kind of surgery and 13% declared having some health problem. The questionnaire pointed out that 36% had low and moderate cardiovascular risk. It could be noticed from the AC that 10% of men and 18% of women had high cardiac risk. Among the tested, 43.2% (24.3% altered and 18.9% borderline) showed high BP on the day of the test, but only 2.7% had self-declared hypertensive. In relation to injury, 36% had already had lesions of some kind, 27.5% of which had occurred in the last 8 months. 66.6% had derived from training or racing competitions and the knee was the mostly affected body part. Only 43% had professional orientation by a physical education teacher during their training and the main reasons for them to begin racing practice were...

Identificar fatores de risco para complicações respiratórias após adenotonsilectomia em crianças ≤ 12 anos com apneia obstrutiva do sono encaminhadas à UTI pediátrica (UTIP). Estudo de coorte histórica com corte transversal que analisou 53 crianças após adenotonsilectomia que preencheram os critérios pré-estabelecidos para encaminhamento à UTIP em um hospital escola de nível terciário. Foram utilizados o teste t de Student, o teste de Mann-Whitney e o teste do qui-quadrado para identificar os fatores de risco. Das 805 crianças submetidas à adenotonsilectomia entre janeiro de 2006 e dezembro de 2012 no hospital escola, 53 foram encaminhadas à UTIP. Vinte e uma crianças (2,6% do total de submetidas à adenotonsilectomia e 39,6% das que foram encaminhadas à UTIP) apresentaram complicações respiratórias, sendo 12 do gênero masculino e a idade média de 5,3 ± 2,6 anos. Maior índice de apneia-hipopneia (IAH; p = 0,0269), maior índice de dessaturação de oxigênio (IDO; p = 0,0082), baixo nadir da SpO2 (p = 0,0055), maior tempo de intubação orotraqueal (p = 0,0011) e rinopatia (p = 0,0426) foram preditores independentes de complicações respiratórias. Foram observadas complicações respiratórias menores (SpO2 entre 90-80%) e maiores (SpO2 ≤ 80%, laringoespasmos, broncoespasmos, edema agudo de pulmão, pneumonia e apneia). Em crianças de até 12 anos e com apneia obstrutiva do sono, aquelas que têm maior IAH, maior IDO, menor nadir da SpO2 e/ou rinopatia são mais predispostas a desenvolver complicações respiratórias após adenotonsilectomia do que aquelas sem essas características.

Neoplasias of the head and neck correspond to the fifth most common cancer in the world, with high mortality and morbidity. The aim of this study was to show, through a literature review, a little about the epidemiology, risk factors, diagnosis and therapy of the most common malignant tumors of each anatomical region of the head and neck. The research of the articles was made in MEDLINE data base, with a total of 52 articles used. In this review, we analyze the main aspects related to the tumors of oral cavity, pharynx, larynx and salivary glands. Almost all cancers of the head and neck affecting the mucosa of the upper aerodigestive tract are derived from squamous cells. Therefore, the risk factors between the various types of tumors are similar, with alcohol and tobacco being the main ones. To be composed of several distinct structures, the head and neck tumors deserve a diagnostic and therapeutic approach individualized for each anatomical region. Controllingthe risk factors and doing the right approach, it is expected that the incidence of cancers of the head and neck decreases, thereby reducing mortality from malignant neoplasms worldwide

Neoplasm, tumor or cancer generic synonymies are used to designate a group of diseases that affect any part of the body.Their main common feature is the abnormal cell proliferation, usually rapid, uncontrolled and unrestrained. According to World HealthOrganization (WHO) cancer is the leading cause of death worldwide. In 2005, a total of 58 million deaths, 7.6 million (or 13%) of all of them were cancer. Among the factors that favor its development, the tobacco is considered one of the main villains. Therefore, this article, we will discuss the basics and updates about oral cancer and tobacco consumption.

Obesity is fundamentally a problem of energy balance that develops when the energy intake is greater than the total energy expenditure (TEE). TEE is composed by the sum of resting energy expenditure (REE), thermal effect of foods and thermal effect of physical activity. Many factors can affect energy expenditure and energy homeostasis. Historically, the energy expenditure has been measured by indirect calorimetry. However, more recently, the use of doubly labeled water has allowed the assessment of energy expenditure in a 24 hour period, which expanded the knowledge on energy metabolism. Factors such as gender, age, thyroid disorders, physical activity and body composition affect REE as already established in the literature. However, there has been speculation whether other factors, such as adipocytokines and diet composition, which might be involved in the genesis of obesity by decreasing the REE. So, this paper aims to review the factors that can alter the energy metabolism.
