O eletroencefalograma (EEG) registra a atividade
elétrica gerada pelo cérebro. De acordo com a sua
frequência, as ondas elétricas cerebrais podem ser
classificadas em cinco tipos. Se o gráfico a seguir
representasse uma onda cerebral, ela seria
classificada como uma onda do tipo:
Um atleta de 60,0 kg realiza um teste ergométrico.
Durante 10 minutos, ele corre sobre uma esteira que
faz um ângulo θ com a horizontal, a uma velocidade
média de 6,0 km/h. Sabe-se que sen(θ) = 0,20 e que a
aceleração da gravidade vale 10 m/s2
. Considere que
a energia bioquímica dos músculos do atleta,
consumida durante o teste, é equivalente à variação
da sua energia potencial gravitacional ao subir, com a
mesma velocidade média, uma rampa com a mesma
inclinação da esteira. Calcule a energia bioquímica que
o atleta consumiu neste teste ergométrico, em kJ (1 kJ
= 103
J).
Suponha que 10% das pessoas de uma população
sejam usuárias de drogas. Um teste para detectar a
presença de drogas produz resultados positivos
corretos para 95% dos usuários de drogas que se
submetem ao teste, e produz resultados negativos
corretos para 95% dos não usuários de drogas. Se
uma das pessoas da população é escolhida ao acaso,
e o resultado do teste é positivo, qual a probabilidade
percentual de a pessoa ser usuária de drogas?
Uma nova terapia, que aumenta as chances de cura e
diminui o tempo de tratamento aos pacientes com
hepatite C, estará disponível no Sistema Único de
Saúde (SUS) no próximo ano. Composto pelos
medicamentos daclatasvir, simeprevir e sofosbuvir, o
novo tratamento vai beneficiar 30 mil pessoas em
2016. Se o governo aumentar a compra destes
medicamentos em 20%, cumulativamente, em cada
ano seguinte a 2016, em quantos anos, contados a
partir de 2016, o número total de beneficiados atingirá
dois milhões? Indique o valor inteiro mais próximo do
obtido. Dados: use as aproximações ln(43/3) 2,70
e ln(1,2) 0,18.
Uma enfermeira deve administrar soro fisiológico
intravenoso em um paciente. O recipiente de soro
possui inicialmente 100 mL. Considere que cada gota
de soro tem volume de 0,050 mL. Logo após o início
da administração do soro, a enfermeira precisa se
ausentar do quarto do paciente por 20 minutos. Qual é
a taxa média de administração do soro que permite
que a enfermeira volte ao quarto no instante em que o
recipiente se esvazia completamente?
A figura a seguir ilustra a maçaneta horizontal de uma
porta. A porta se abre quando uma força vertical para
baixo é aplicada no ponto A, com módulo maior ou
igual a 12 N. Se a força vertical para baixo for aplicada
no ponto B, qual é o seu menor módulo capaz de abrir
a porta?
Hematócrito é a porcentagem de volume ocupada
pelos glóbulos vermelhos no volume total de sangue.
Se uma mulher tem 42% de hematócrito e um volume
total de sangue de 4,8 litros, quantos litros do seu
sangue é formado por glóbulos vermelhos?
Um princípio ativo está disponível em concentrações
de 15% e 24%. Misturando as concentrações
disponíveis, pretendemos obter 90 ml deste princípio
ativo com concentração de 20%. Quanto deve ser
usado da concentração de 15%?
Segundo a Organização Mundial da Saúde (OMS), o
consumo diário de açúcar, sem incluir o açúcar
presente nas frutas, legumes e no leite, não deve
ultrapassar 50 g, sob o risco de criar sérios problemas
para a saúde. Se uma colher de açúcar pesa 4 g, e
uma pessoa adoça um cafezinho usando uma colher e
meia de açúcar, qual o número máximo de cafezinhos
que esta pessoa pode tomar diariamente, de modo a
não ultrapassar o limite recomendado pela OMS?
Indique o valor inteiro mais próximo do obtido.
A endocrinologista Dra. Paula prescreveu dois gramas
diários da droga Glifage XR para um paciente. A
Farmácia Popular do Ministério da Saúde disponibiliza
o Glifage XR em comprimidos de 500 mg. Quantos
comprimidos mensais do Glifage XR devem ser
disponibilizados na Farmácia Popular ao paciente?
Admitindo que o mês tem trinta dias.

OBESITY
Is it a disease or a lifestyle problem?
Obesity is a serious health problem in the United States and
increasingly around the world. Costs and associated
diseases continue to increase. Recent studies into the
causes of obesity indicate that the problem is more
complex, and may have less to do with “willpower” and other
such issues, than previously thought. Many obesity experts
hope this research will help physicians and others rethink
the way they understand and treat the problem. Skeptics,
however, continue to blame inactivity and overeating for
obesity. While the World Health Organization (WHO) and
others call for a reduction in sugar consumption to combat
obesity, the food industry says it is being unfairly targeted.
The planet’s population is getting fatter. Once a problem
largely confined to high-income regions, overweight and
obesity are on the rise in low- and middle-income
countries. According to the World Health Organization
(WHO), obesity has more than doubled worldwide since
1980. In 2014 more than 1.9 billion adults (39 percent of
Earth’s adult population) were overweight. That includes
600 million who were obese.
Among children, overweight and obesity are increasing
more than 30 percent faster in lower-and middle-income
countries than in developed countries. In 2013, 42 million
children under the age of 5 worldwide were overweight or
obese.

Treating Alzheimer’s Disease
Are scientists close to finding a cure?
The number of Americans suffering from Alzheimer's, a degenerative brain disease, is projected to more than double by 2050, from 5.3 million today to 13.8 million. At the same time, as Baby Boomers age and medical expenses rise, the cost of treating and caring for people with the disease is expected to rise fivefold to $1.1 trillion. No treatment can yet prevent or cure Alzheimer's. However, advances in brain science and diagnostic technologies are creating breakthroughs unimagined even a few years ago. Rapidly expanding knowledge in genetics, neuroscience, biology and computing is leading to clinical trials on potential new drug therapies, research on how to prevent the disease and new tests to help diagnose it — perhaps even before symptoms appear. Scientists are debating whether the main hypothesis of what causes the disease — a buildup of amyloid protein into plaques that kill nerve cells in the brain — is correct. Patient advocates say federal Alzheimer's research is underfunded, but Congress is clearing the way for more research funds.
