    Tempos ansiosos


    (1) Saber lidar com as preocupações se tornou uma característica desejada, porque a ansiedade foi relegada ao posto de vilã do mundo moderno. Apesar de ser essencial para a sobrevivência, ela ganhou o estigma de atrapalhar as relações pessoais, a competência no trabalho e todo tipo de situação delicada.

    “Se o candidato não consegue dominar a ansiedade na hora da seleção de emprego, já questionamos como ele agirá no ambiente de trabalho”, diz Adriana Vilela, analista de recursos humanos da RHBrasil, empesa que recruta candidatos para o mercado de trabalho. É muito comum, aliás, as pessoas reclamarem que são ansiosas demais e os especialistas chamarem os nossos tempos de “era da ansiedade”.

    (2) Mas essa noção de que vivemos numa época especialmente estressante é coisa ultrapassada, na verdade. A ideia de “era da ansiedade” nasceu antes da internet e do computador. Apareceu pela primeira vez em 1947, num poema do inglês Hugh Auden, que, desiludido com a humanidade depois da 2ª. Guerra Mundial, criticou o homem e sua busca sem sentido por significado.

    Desde então, há pelo menos uma obra por década que afirma que o ser humano está passando pelos tempos mais difíceis de sua história e que, coitados de nós, sofremos demais com a ansiedade.

    More than half your body is not human


    Human cells make up only 43% of the body's total cell count. The rest are microscopic colonists.

    Understanding this hidden half of ourselves - our microbiome - is rapidly transforming understanding of diseases from allergy to Parkinson's.

    No matter how well you wash, nearly every nook and cranny of your body is covered in microscopic creatures.

    This includes bacteria, viruses, fungi and archaea (organisms originally misclassified as bacteria). The greatest concentration of this microscopic life is in the dark murky depths of our oxygen-deprived bowels.

    The human genome - the full set of genetic instructions for a human being - is made up of 20,000 instructions called genes.

    But add all the genes in our microbiome together and the figure comes out between two and 20 million microbial genes.

    Prof Sarkis Mazmanian, a microbiologist from Caltech, argues: "We don't have just one genome, the genes of our microbiome present essentially a second genome which augment the activity of our own.

    Science is rapidly uncovering the role the microbiome plays in digestion, regulating the immune system, protecting against disease and manufacturing vital vitamins.

    It is a new way of thinking about the microbial world. To date, our relationship with microbes has largely been one of warfare.

    Antibiotics and vaccines have been the weapons unleashed against the likes of smallpox, Mycobacterium tuberculosis or MRSA.

    That's been a good thing and has saved large numbers of lives.

    But some researchers are concerned that our assault on the bad guys has done untold damage to our "good bacteria".

    Prof Knight has performed experiments on mice that were born in the most sanitised world imaginable.

    He says: "We were able to show that if you take lean and obese humans and take their faeces and transplant the bacteria into mice you can make the mouse thinner or fatter depending on whose microbiome it got."

    "This is pretty amazing right, but the question now is will this be translatable to humans"

    This is the big hope for the field, that microbes could be a new form of medicine. It is known as using "bugs as drugs".

    TEXTO 1


    A realidade da saúde no Brasil.


    (1) A crise da saúde no Brasil vem de longa data e continua presente. Frequentemente, nos deparamos com notícias de filas de pacientes nos hospitais públicos, além da falta de leitos, equipamentos etc. E, no meio da crise, está a população que precisa de atendimento, e estão os médicos que, quase sempre, atuam em condições precárias.
    (2) Independente do jogo de empurra-empurra, há escassez de recursos financeiros, materiais e humanos, para manter os serviços de saúde operando com eficiência. Problemas, como atraso no repasse dos pagamentos do Ministério da Saúde, baixos valores pagos pelo SUS aos procedimentos médico-hospitalares consolidam o entrave no setor. O mundo econômico da saúde é cruel. Segundo estatísticas oficiais, são gastos R$ 31 bilhões para cuidar de 35 milhões de segurados, enquanto todo o SUS, para suprir o direito à saúde de mais de 145 milhões de brasileiros, gasta quase a mesma quantia. Por essas razões, nos encontramos no 124º lugar no ranking da OMS em qualidade de saúde.
    (3) É difícil para qualquer especialista apontar apenas um motivo para tal crise. Mesmo com a evolução do contexto político-social pelo qual o Brasil passou, pouco mudou. Na realidade, em 500 anos de Brasil, independentemente do regime vigente, a saúde nunca ocupou lugar de destaque. Só se olhou atentamente para o setor quando certas epidemias representaram eminentes ameaças à sociedade.
    (4) É assim desde o Brasil Colônia, quando o país não dispunha de um modelo de atenção à saúde e nem mesmo do interesse em criá-lo, por parte do governo colonizador. As noções empíricas (a cargo dos curandeiros) eram a opção. Com a vinda da família real ao Brasil, se fez necessária a organização de uma estrutura sanitária mínima, capaz de dar suporte ao poder que se instalava no Rio de Janeiro. A carência de médicos no Brasil Colônia e no Brasil Império era enorme. Para se ter uma ideia, no Rio, em 1789, só existiam quatro médicos exercendo a profissão. Em outros estados, eram mesmo inexistentes, o que fez com que proliferassem pelo país os Boticários, a quem cabia a manipulação das fórmulas prescritas pelos médicos.
    (5) Veio a República, e o Brasil continuou o mesmo. No início do século passado, a cidade do Rio apresentava um quadro sanitário caótico, com doenças graves que acometiam a população, como varíola, malária e febre amarela. Isso gerou sérias consequências tanto para a saúde coletiva quanto para o comércio exterior, já que navios estrangeiros evitavam atracar no porto do Rio. Poderíamos escrever muito mais sobre o tema e chegaríamos à mesma conclusão: em pleno século XXI, no Brasil, pouco se evoluiu em política de saúde.
    (6) Dados do Conselho Federal de Medicina revelam que a má distribuição de médicos no país ainda persiste. São 65,9% deles atuando nas regiões Sul e Sudeste, onde se concentra apenas cerca de 25% da população.
    (7) É a saúde continuando um sistema embrionário e contraditório, pois nos destacamos mundialmente por nossas pesquisas pioneiras, no combate a Aids, por exemplo, mas não conseguimos dar atendimento básico à maioria do povo.

    The Healing Power of Music


    What better “medicine” than a “treatment” that has only positive side effects and “therapy” that is actually enjoyable? Music is shown to have the ability to help organize the brain; especially vital to those who are afflicted with Alzheimer’s.

    Studies have shown that the results of a musical therapy session last for several hours afterward. Positive results include elevated mood, increased socialization and appetite and reduction in agitation. These benefits are attributed to the stimulation the brain receives during a music therapy session, a sort of “cognitive workout”.

    As speech, writing and traditional forms of communication are compromised, music provides an alternative means of maintaining a connection, thereby helping to normalize interaction between caregiver and patient. Music used therapeutically creates an environment where the patient can be nurtured and cared for in a way that is safe, gentle and appropriate. Music is central to maintaining human bonds when those with dementia have lost the ability to initiate communication or to respond verbally.

    The powers of music when focused and used therapeutically are many. Critical to maintaining quality of life for those with Alzheimer’s is management of emotions and preserving the connection with others. Music is conducive to keeping those connections strong as long as possible while helping the participant to focus, increase awareness and orient to the environment. A number of research studies have looked at music therapy as an important adjunct to medical treatment and findings suggest a possible link between the use of music and slowing the progression of dementia.

    Music is primal to life and expressed by each of us every day whether through dancing to a favorite tune, keeping rhythm with a pencil or remembering a special time when hearing a forgotten melody. It is central to our lives and is embedded in our culture, defining how we acknowledge milestones, rites of passage and celebrations as well as providing comfort, transformation and inspiration.

    Yellow Fever — Once Again on the Radar Screen in the Americas


    Over the past several weeks, a fifth arbovirus, yellow fever virus, has broken out in Brazil, with the majority of the infections occurring in rural areas of the country. These are referred to as sylvatic, or jungle, cases, since the typical transmission cycle occurs between forest mosquitoes and forest-dwelling nonhuman primates, with humans serving only as incidental hosts. In this ongoing outbreak, health authorities have reported 234 confirmed infections and 80 confirmed deaths as of February 2017. Confirmed infections have occurred in the Brazilian states of Minas Gerais, Espírito Santo, and São Paulo, and hundreds of additional cases remain under investigation. The high number of cases is out of proportion to the number reported in a typical year in these areas.


    Although there is currently no evidence that human-tohuman transmission through Aedes aegypti mosquitoes (urban transmission) has occurred, the outbreak is affecting areas in close proximity to major urban centers where yellow fever vaccine is not routinely administered. This proximity raises concern that, for the first time in decades, urban transmission of yellow fever will occur in Brazil.


    Yellow fever is the most severe arbovirus ever to circulate in the Americas, and although vaccination campaigns and vector-control efforts have eliminated it from many areas, sylvatic transmission cycles continue to occur in endemic tropical regions. The most recent outbreak in Brazil highlights this phenomenon. If the current outbreak leads to urban spread through A. aegypti mosquitoes, clinicians should adopt a high index of suspicion for yellow fever, particularly in travelers returning from affected regions. As with all potentially reemerging infectious diseases, public health awareness and preparedness are essential to prevent a resurgence of this historical threat.

    Death of The Death Care Industry


    Death is a dying industry with an economic phenomenon. As Americans perceived value of “traditional” funerals diminish, the cost of funerals have increased nearly 1,328% in just four decades. In 1960 the average cost of a funeral was $706 when only 3.56% of bodies were cremated. Today the average traditional funeral costs between $8,000 and $10,000, and about 42% of people are cremated. The US funeral industry accounts for about $20 billion in annual economic activity, with around 130,000 employees that make a living on the 1.5 million people that go to rest each year. 

    Many communities have turned a blind eye to what goes on inside funeral homes, as many people prefer not to know the ins and out of the business. In addition, grieving customers in need of funeral goods and services may not be in a healthy state of mind to make financial decisions. Grief has similar side effects of alcohol consumption, such as numbness, guilt, and depression, resulting in less alert and price sensitive customers. In addition, the funeral industry is somewhat taboo in the sense that communities in general don’t communicate with one another about what are acceptable practices in this industry. 

    Some funeral service providers have taken advantage of this by encouraging the lack of transparency in the industry, charging exorbitant prices for funeral goods and services and charging people who appear to be wealthy higher prices. After Jessica Mitford published The American Way of Death in 1963, to expose the abuses in the funeral industry, a groundswell of support for government  intervention followed. Under President Ronald Reagan The Funeral Rule was first enacted to protect consumers from deceptive practices, but the rule has yet to put the nail in the coffin.

    Global sleeping patterns revealed by app data.
    It showed the Dutch have nearly an hour more in bed every night than people in Singapore or Japan.
    The study, published in Science Advances, also found women routinely get more sleep than men, with middle-aged men getting the least of all.
    The researchers say the findings could be used to deal with the "global sleep crisis".
    The study found people in Japan and Singapore had an average of seven hours and 24 minutes sleep while the people in the Netherlands had eight hours and 12 minutes.
    People in the UK averaged just under eight hours - a smidgen less than the French.
    The later a country stays up into the night, the less sleep it gets. But what time a country wakes up seems to have little effect on sleep duration.
    Prof Daniel Forger, one of the researchers, said there was a conflict between our desire to stay up late and our bodies urging us to get up in the morning.
    The study also showed women had about 30 minutes more per night in bed than men, particularly between the ages of 30 and 60.
    And that people who spend the most time in natural sunlight tended to go to bed earlier. A strong effect of age on sleep was also detected. A wide range of sleep and wake-up times was found in young people but "that really narrows in old age," said Prof Forger.
    "It highlights that although our body clocks are programming us to do certain things, we can't as we're ruled by social circumstances.
    "We won't know the long-term consequences of this for many years."

    An accident took her sight 21 years ago; another just gave it back
    After a car accident injured her spine in 1995, Mary Ann Franco lost her vision. But after being blind for 21 years, the Florida woman fell in her home and hurt her neck ... and woke up from the ensuing spinal surgery on April 6 with the ability to see. "Out the window, I could see the trees. I could see the houses and stuff," Franco tells WPBF. Oddly, Franco was colorblind before her car accident, and now she can also see colors. The neurosurgeon who operated on her says he has no scientific explanation for what happened— Dr. John Afshar tells ABC News it's a "true miracle"—but he has an idea. If an artery in Franco's spine was "kinked" in the car accident, restricting the flow of blood to the part of her brain that handles vision, he may have inadvertently "unkinked" the same artery during the recent surgery, he theorizes. "And when we gave that extra amount of blood flow by unkinking the vessel, it could have reestablished the blood flow," he tells WPBF, though he notes that none of this is certain. But an explanation doesn't matter much to Franco: "The sun is coming through the trees," she said on a recent morning. "Oh God, it’s so wonderful to see." Nature isn't the only sight for her to behold: Franco has seven grandchildren and two great grandchildren who WPBF notes she has hugged and kissed but never seen.

    Lack of autonomy and respect threatens 'doctorness,' physicians say.
    Doctors say that “doctorness”—the traditional way that physicians practice medicine—is threatened, a new study reported. These threats include the increasing complexity of the health care landscape, combined with today’s technology-enabled consumer, according to the “Truth About Doctors” study conducted by marketing services firm McCann.
    The study found that the pressures of today’s world have not only stolen time and autonomy from doctors, but have simultaneously demanded they do more on someone else’s agenda.
    “The autonomous, entrepreneurial role the doctor has played in the past has changed dramatically. In the last five years, doctors have gone from being the lynchpin in the health care system to a devalued cog in a larger wheel,” said co-author of the study Hilary Gentile.
    The research involved interviews with 450 doctors across the United States.
    Study co-author Laura Simpson added, “Modern-day doctors have become trapped in a paradoxical standard where they’re expected to forge a warm relationship with patients, yet operate with the cold precision of a machine. In our real-time, know-it-all culture, their authority and respect are eroding right under their feet.”
    In addition to the physician interviews, this research revealed that nearly one-third of Americans between the ages of 18 and 34 think they could be doctors with little or no training.
    “People think that because they can go on WebMD, they understand what we understand,” said one physician quoted in the report. “We have studied and seen so much, but people just don't value or respect that anymore.”
    “Of doctors who said that, on average, technology such as WebMD and wearable devices are bad for patients, the number one risk they cited of this technology is that patients misdiagnose themselves (74%),” Ms. Simpson said. “Fiftyseven percent also said that patients don’t take the doctor’s advice because they think they know better.”

    Stretchable hydrogel can be used as a 'smart bandage' and delivery vehicle for medical devices.
    Engineers at MIT have developed an elastic yet sturdy hydrogel material that can be used as flexible, biocompatible wound dressing and as a smart delivery method for drugs or medical devices.

    The material was designed to be embedded with medicallyuseful electronics, such as conductive wires, semiconductor chips, LED lights, and temperature sensors, according to a study published online December 7, 2015 in the journal Advanced Materials.
    Electronics coated in the hydrogel could be placed not only on the surface of the skin but also inside the body—such as implanted biocompatible glucose sensors or soft, compliant neural probes, the researchers wrote.

    “Electronics are usually hard and dry, but the human body is soft and wet. These two systems have drastically different properties,” said lead investigator Xuanhe Zhao, Associate Professor in MIT’s Department of Mechanical Engineering.

    Dr. Zhao explained, “If you want to put electronics in close contact with the human body for applications such as health care monitoring and drug delivery, it is highly desirable to make the electronic devices soft and stretchable to fit the environment of the human body. That’s the motivation for stretchable hydrogel electronics.”

    Current hydrogels are often brittle and made of degradable biomaterials that don’t last long, he explained. So, his team designed a hydrogel that is not only as flexible as human soft tissues, but can bond strongly to non-porous surfaces such as gold, titanium, aluminum, silicon, glass, and ceramic.

    How stress affects your health

    Stress: We've all felt it. Sometimes stress can be a positive force, motivating you to perform well at your piano recital or job interview. But often — like when you're stuck in traffic — it's a negative force. If you experience stress over a prolonged period of time, it could become chronic — unless you take action.

    Even short-lived, minor stress can have an impact. You might get a stomach-ache before you have to give a presentation, for example. More major acute stress, whether caused by a fight with your spouse or an event like an earthquake or terrorist attack, can have an even bigger impact.

    Multiple studies have shown that these sudden emotional stresses — especially anger — can trigger heart attacks, arrhythmias and even sudden death.

    When stress starts interfering with your ability to live a normal life for an extended period, it becomes even more dangerous. The longer the stress lasts, the worse it is for both your mind and body. You might feel fatigued, unable to concentrate or irritable for no good reason, for example. But chronic stress causes wear and tear on your body, too.

    Stress can make existing problems worse. In one study, for example, about half the participants saw improvements in chronic headaches after learning how to stop the stressproducing habit of “catastrophizing,” or constantly thinking negative thoughts about their pain. Chronic stress may also cause disease, either because of changes in your body or the overeating, smoking and other bad habits people use to cope with stress. Other forms of chronic stress, such as depression and low levels of social support, have also been implicated in increased cardiovascular risk. And once you're sick, stress can also make it harder to recover. One analysis of past studies, for instance, suggests that cardiac patients with so-called “Type D” personalities — characterized by chronic distress — face higher risks of bad outcomes.
