The 193-Member United Nations General Assembly today formally adopted the 2030 Agenda for Sustainable Development, along with a set of bold new Global Goals, which Secretary-General Ban Ki-moon hailed as a universal, integrated and transformative vision for a better world.
Several new fitness trackers, along with heart rate monitors, allow users to constantly measure their heart rate throughout the day. For the average person, this information may be interesting, but it remains to be seen whether it can help make you healthier, experts say.
Heart rate monitors geared toward athletes have been available for years, but recently, fitness trackers aimed at the general public have started to include heart rate as a measure to track along with steps taken, calories burned, distanced walked and sleep.
For example, the Withings Pulse includes a sensor that lets you check your heart rate using your finger, and the Basis B1 has heart rate monitor built into the wristband itself, allowing you to know your rate at any time. (The Basis also graphs this information, so users can see how their heart rate changed during the day or night.)
Knowing your heart rate can be useful when you exercise, because it will help you know whether your exercise is intense enough to provide health benefits, but not so intense that it could cause health problems, said Dr. James Borchers, a sports medicine physician at Ohio State University Wexner Medical Center. This sweet spot is known as the "target zone," which is about 60 to 80 percent of your maximum heart rate, according to the Cleveland Clinic. [The Best Heart Rate Monitor Watches for Exercise]
Neuroscientists have found a key molecular difference between males and females in how synapses are regulated in the hippocampus. The findings suggest that female and male brains may respond differently to drugs, such as endocannabinoids, that target synaptic pathways.
“The importance of studying sex differences in the brain is about making biology and medicine relevant to everyone, to both men and women,” says Catherine S. Woolley, senior author of the study published in the Journal of Neuroscience and a neurobiology professor at Northwestern University. “It is not about things such as who is better at reading a map or why more men than women choose to enter certain professions.”
A drug called URB-597, which regulates a molecule important in neurotransmitter release, had an effect in females that it did not have in males, the research shows. While the study was done in rats, it has broad implications for humans because this drug and others like it are currently being tested in clinical trials in humans.
“Our study starts to put some specifics on what types of molecular differences there are in male and female brains,” Woolley says. “We don’t know whether this finding will translate to humans or not,” Woolley says, “but right now people who are investigating endocannabinoids in humans probably are not aware that manipulating these molecules could have different effects in males and females.”
Background: The vogue of social media has changed interpersonal communication as well as learning and teaching opportunities in medical education. The most popular social media tool is Facebook. Its features provide potentially useful support for the education of medical students but it also means that some new challenges will have to be faced.
Aims: This review aimed to find out how Facebook has been integrated into medical education. A systematical review of the current literature and grade of evidence is provided, research gaps are identified, links to prior reviews are drawn and implications for the future are discussed.
Method: The authors searched six databases. Inclusion criteria were defined and the authors independently reviewed the search results. The key information of the articles included was methodically abstracted and coded, synthesized and discussed in the categories study design, study participants’phase of medical education and study content.
Results: 16 articles met all inclusion criteria. 45-96% of health care professionals in all phases of their medical education have a Facebook profile. Most studies focused on Facebook and digital professionalism. Unprofessional behavior and privacy violations occurred in 0.02% to 16%. In terms of learning and teaching environment, Facebook is well accepted by medical students. It is used to prepare for exams, share online material, discuss clinical cases, organize face-to-face sessions and exchange information on clerkships. A few educational materials to teach Facebook professionalism were positively evaluated. There seems to be no conclusive evidence as to whether medical students benefit from Facebook as a learning environment on higher competence levels.
Discussion: Facebook influences a myriad of aspects of health care professionals, particularly at undergraduate and graduate level in medical education. Despite an increasing number of interventions, there is a lack of conclusive evidence in terms of its educational effectiveness. Furthermore, we suggest that digital professionalism be integrated in established and emerging competency-based catalogues.
Intracerebral hemorrhage remains a serious condition for which early aggressive care is warranted. These guidelines provide a framework for goal-directed treatment of the patient with intracerebral hemorrhage.
The patient was dying and she knew it. In her mid-50s, she had been battling breast cancer for years, but it had spread to her bones, causing unrelenting pain that required hospitalization. Jeremy Force, a first-year oncology fellow at Duke University Medical Center who had never met the woman, was assigned to stop by her room last November to discuss her decision to enter hospice.
Employing the skills he had just learned in a day-long course, Force sat at the end of her bed and listened intently. The woman wept, telling him she was exhausted and worried about the impact her death would have on her two daughters.
US researchers claim to have developed a single test that is able to identify past exposure to every known human virus infection, using a drop of blood.
The technique decodes the infection history imprinted in our immune response.
The scientists hope that the test will eventually provide important insight into how viruses contribute to development of a range of diseases.
The work was published in the journal Science.
During a virus infection, your immune system generates antibodies designed to fight the virus. Each antibody recognises a tiny fragment of the virus and their interaction is very specific - they fit like a lock and key.
Virus-specific antibodies can be long-lived; often persisting many years after an infection has disappeared. So, your antibody repertoire represents a historical record of all of the viruses that have infected you.
This immunological catalogue has been used for years to identify past virus exposure, but the diagnostic tests routinely used have been limited to one, or at most a few, different virus strains.
New research has shown for the first time that traces of our poor lifestyles, environmental stressors and trauma can be passed down to future generations through our DNA, potentially making our children more prone to conditions such as mental illness and obesity.
Scientists already knew that significant traumatic events such as famine could leave their mark on future generations, but this is the first time they’ve been able to observe the mechanism by which this happens. And they've found that, contrary to previously assumed, our genetic slate doesn't get completely wiped clean for our offspring.
The team have now been able to describe this epigenetic erasing process in humans - which occurs between weeks two and nine of an embryo's development - for the first time, and have shown that not all of these environmental changes get wiped clean. In fact, around 5 percent of our DNA is resistant to reprogramming, and can carry our mistakes onto the next generation, their research revealed.
These erase-resistant genes are particularly active in brain cells, and are associated with conditions such as schizophrenia, obesity and metabolic disorders, according to the researchers.
Here are just a few of the things you can use social to do:
1. Build your healthcare brand. Social media can help raise awareness of your brand in your community—whether that's local, regional or national.
2. Highlight your staff and services. Quality healthcare is more important than ever. And social media channels are a great place to highlight your expertise. For example, you might promote blog posts written by specialists, post videos about your service lines, or host Q&A sessions about important health topics.
3. Deepen connections. Social media gives you a chance to commune with healthcare consumers. You can hear—and share—personal and powerful stories and connect directly. And social can give people an everyday look at who you really are—highlighting your caring staff and culture.
4. Discover positives—and problems. People are probably talking about your hospital or health plan on social media already. Maybe they're raving about your classes or the healthcare their loved ones received. But they could be grumbling too. If you're not available on social, you won't know about these conversations. That means you'll miss the opportunity to see successes and show off your great customer service when someone has a complaint.
5. Share trustworthy and valuable health content. Let's face it: Social media can be a hotbed for bad health information that can spread and cause harm, from fad diets to false claims. You can help counter that. By sharing reliable, reader-friendly materials and tips, you can help serve and protect your community—and become a go-to source when people need answers or help.
6. Support your other marketing channels. Looking to bring more people to your website? Hoping to up your hospital or health plan's e-newsletter subscriptions? Social media can get the word out.
7. Communicate with your followers during a crisis. When a tragedy strikes, people often turn to social media to get news and connect with others who are affected. As a healthcare leader, your hospital or health plan can be a valuable voice in those discussions, providing up-to-date information and trustworthy advice.
Health in All Policies (HiAP) is a collaborative approach that integrates and articulates health considerations into policymaking across sectors to improve the health of all communities and people. HiAP recognizes that health is created by a multitude of factors beyond healthcare and, in many cases, beyond the scope of traditional public health activities.
“Once you really understand the truth behind the lies in a given arena, then you can finally back up far enough and see the actual reasons for the lies. You can see the secret program the lies are protecting. You can see why the program is being pushed. You can see what most people would rather not see.”
In many previous articles, I have established a number of facts about vaccines.
They are not safe. They are not effective. They were not responsible for the major decline in so-called contagious diseases.
In most if not all cases, the diseases they are supposed to prevent affect only a tiny fraction of the people claimed to be at risk.
In some instances, (e.g., seasonal flu, Swine Flu, SARS), the “outbreaks” have virtually nothing to do with the viruses touted as the cause of illness. Therefore, even if vaccines were safe and effective, they would have no relevant effect, because they are targeting viruses which are not causing illness.
The rabid claim that unvaccinated children pose a threat to vaccinated children is, on its face, a lunatic self-contradiction, since those who are vaccinated are supposed to be protected.
Having established these points, it’s possible to assess the real reasons for the push to vaccinate every human on the face of the Earth...
Allergies are on the rise across the developed world and hay fever and eczema have trebled in the last 30 years. Yet allergies are an area of much confusion and concern. Although 40% of people report having a food allergy, in fact only 1-5% do, and allergists commonly report spending most of their consultations refuting firmly held beliefs that have no scientific foundation.
Theories about allergy – some from medical research and some from lifestyle “gurus” – have led to conflicting information, making it hard to know what to believe. Because of this, Sense About Science worked with me and a number of allergists, immunologists, respiratory scientists and pharmacists to produce Making Sense of Allergies, a guide tackling the many myths and misconceptions about allergies. One common myth – something that I work on – is the link between allergies and exposure to microbes.
So here is a hygiene and allergy reality fact check:
Alzheimer’s disease may have evolved alongside human intelligence, researchers report in a paper posted this month on BioRxiv.
The study finds evidence that 50,000 to 200,000 years ago, natural selection drove changes in six genes involved in brain development. This may have helped to increase the connectivity of neurons, making modern humans smarter as they evolved from their hominin ancestors. But that new intellectual capacity was not without cost: the same genes are implicated in Alzheimer's disease.
Kun Tang, a population geneticist at the Shanghai Institutes for Biological Sciences in China who led the research, speculates that the memory disorder developed as ageing brains struggled with new metabolic demands imposed by increasing intelligence. Humans are the only species known to develop Alzheimer's; the disease is absent even in closely related primate species such as chimpanzees.
Tang and his colleagues searched modern human DNA for evidence of this ancient evolution. They examined the genomes of 90 people with African, Asian or European ancestry, looking for patterns of variation driven by changes in population size and natural selection.
