WEDNESDAY, Oct. 16, 2019 — Giant dinosaurs, such as long-necked sauropods, evolved special cooling systems to prevent overheating and brain damage, according to a new study.
“Small dinosaurs could have just run into the shade to cool off, but for those giant dinosaurs, the potential for overheating was literally inescapable,” said study co-author Lawrence Witmer, a professor of anatomy at Ohio University in Athens, Ohio. “They must have had special mechanisms to control brain temperature, but what were they?”
The answer was found in everyday experience: Air-conditioners use evaporation, and it’s the evaporative cooling of sweat that keeps people comfortable in summer. So, not surprisingly, when researchers examined modern-day relatives of dinosaurs — birds and reptiles — they found that evaporation of moisture in the nose, mouth and eyes cooled blood on its way to the brain.
The investigators used 3D imaging of fossils to reveal multiple heat exchangers in dinosaur heads.
Lead author Ruger Porter, an assistant professor of anatomical instruction, said, “The handy thing about blood vessels is that they basically write their presence into the bones. The bony canals and grooves that we see in modern-day birds and reptiles are our link to the dinosaur fossils. We can use this bony evidence to restore the patterns of blood flow in extinct dinosaurs and hopefully get a glimpse into their thermal physiology and how they dealt with heat.”
The study was published Oct. 16 in the journal Anatomical Record.
Sharon Swartz of the National Science Foundation, which funded the research, said the findings show how the physical constraints imposed by specific environmental conditions shaped dinosaurs’ evolution.
“Using a combination of technological innovation and biological expertise, these researchers were able to take a direct reading from the fossil record that provides new clues about how dinosaur skeletal form and function evolved,” she said.

If you are a CBD user, you should know that a lot of factors can affect the way your body processes CBD. There is only one clear thing – it will not stay in your body for longer than one week. At the moment, scientists are still conducting studies to learn more about it.
CBD may remain longer in your body in case you have a slow metabolism. Factors such as frequency of use, dosage, method of administration can also influence the presence of CBD in your body.
If you are about to pass a drug test, you should start flushing out the drug toxins as soon as possible. There are a lot of home remedies that can help you pass the test. First of all, you should drink plenty of water, tea, and cranberry juice to urinate as often as possible.
Secondly, start eating high-fibre foods, including vegetables and fruits. Besides that, you should do some aerobic exercises, try hiking, jogging, or biking. Some experts also recommend going to the sauna in order to start sweating.
If you are not sure whether you still have CBD in your body, consider using synthetic urine for the test.
Quick fix 6.2 can help you avoid undesired consequences. The best thing is that it comes with heating pads inside of the package – it makes the product warm and authentic.

THURSDAY, July 18, 2019 — More than 3 million kids are hospitalized in the United States every year. Whether it’s for a planned test or surgery or an injury or other emergency, knowing how to be involved in your child’s care can help you get through what’s often a stressful event.
The single most important thing you can do is be an active member of your child’s health care team, taking part in every decision, according to the Agency for Healthcare Research and Quality. Learn as much as you can about your child’s condition and needed tests and treatments from the medical staff and other reliable sources. Ask if the doctor’s recommendations are based on the latest scientific evidence.
Get to know all the members of the care team, especially the lead physician, and make sure each has all of your child’s important health information — from allergies to what vitamins and prescription drugs, if any, he or she takes.
If you have a choice, use a hospital with a lot of experience in the procedure or surgery your child needs — research shows that this leads to better results.
While your child is in the hospital, don’t be afraid to speak up if you see something out of the norm or even if health care workers neglect to wash their hands, an important way to prevent the spread of infections.
Ask why each test or procedure is being done, how it can help and when results will be available so that you’re not stressed over how long it’s taking. If your child is having surgery, make sure that you, your child’s doctor and the surgeon all agree and are clear on exactly what will be done. On the other hand, be prepared to answer the same questions over and over — it may seem tedious but it helps prevent mistakes.
Before your child goes home, ask the team to go over his or her care plan, including any needed medication and/or restrictions on their activities. Speak up if you have any questions. Take notes or ask a loved one to do it for you.
The U.S. Department of Health and Human Services has more tips on preventing hospital errors to help parents safeguard their children.
FRIDAY, May 10, 2019 — While it’s a regular ritual, spring cleaning can become a dangerous chore for your health, experts warn.
Some cleaning supplies — air fresheners, rug cleaners, bleach, oven cleaners and floor polish — have dangerous chemicals such as volatile organic compounds.
These chemicals become vapors that can irritate the nose, throat, eyes and lungs, said Dr. Timothy Craig, an allergist and immunologist at Penn State Health.
“The nose provides a helpful warning signal,” he added in a health system news release. “If someone’s nose becomes irritated while cleaning, it’s safe to assume his or her lungs will be irritated, too.”
“For most people, using chemical cleaners occasionally would not create clinically significant reductions in lung function,” Craig said.
“But repeated exposure to harmful chemicals over a lifetime could lead to significant disability later in life, especially for people with asthma, chronic obstructive pulmonary disease [COPD] or Alpha 1 antitrypsin deficiency, a genetic disorder that may cause lung or liver disease,” he warned.
“We all clean with bleach and other chemicals from time to time,” said Dr. Ann Bogdan, a family health physician from Penn State Health Medical Group-Mechanicsburg. “But I encourage my patients to be careful when doing so.”
The doctors offer these six safety precautions while spring cleaning.
Don’t combine chemical cleaners. “In particular, never mix ammonia and bleach,” Bogdan said. This can result in dangerously toxic vapors.
While cleaning, be sure to have proper ventilation by opening a window or running a fan.
Wear rubber gloves. “Without them, you run the risk of developing redness or rashes on your hands,” Craig said.
Try using old-fashioned cleaners. “Diluted vinegar works well to clean windows, and baking soda gives you scrubbing power,” Bogdan said.
Read labels and look for volatile organic compounds and other potential irritants, even in products labeled as “green” or “healthy.”
Look for products with the “Safer Choice” logo, which the U.S. Environmental Protection Agency deems as “safer for human health and the environment.”
And their final advice: If you develop coughing, wheezing, throat soreness or eye watering while using chemical cleaners, step into another room or walk outside. If the symptoms persist even after leaving the room, call a doctor.
Many people wonder just how long does weed stay in your system? The short answer is that it varies depending on how much of it is in your system. Today I’ll break down the facts behind the question that many people have as well as offer up some solutions to get weed out of your system.
The Facts About Weed (Marijuana) Being In Your System
Pot, mary jane, dope, weed, marijuana, or cannabis. Call it what you want, but the facts remain the same – it’s detectable in your bodily fluids for a span of one to 30 days after the last time you used it. In some cases, it may be able to be detected for up to many months. This all depends on how much you ingest (or smoke), as well as how frequent you are doing this. It shouldn’t be of any surprise to you that the more you do it, and the higher dose you ingest, the longer it’ll stay in your system and be detectable.
If you use it daily, you can expect the cannabis to be detectable for many months after the last time it’s used. Some detection times will span beyond 90 days in length.
I’m also going to break down urine, blood, saliva, and hair and share with you what I know about the detection windows for finding it in your system, so pay close attention and you can rest assured I’ll share with you some game changing tips that can benefit you as you go through corporate drug testing.
How Long is Marijuana Detectable in Drug Testing?
When you perform drug tests, it’s important that you know they are designed to measure and record marijuana and it’s by-products, also called metabolites. The latter will be found in your system way after you get the high from weed, which let’s be honest, is a big reason many people smoke it.
Drug tests measure marijuana and its by-products, or metabolites. These metabolites remain in your system long after weed’s effects have worn off.
Marijuana can be detected in your urine for the below amounts of time. (Each one is based on the last use date.)
Chronic heavy users (using many occasions throughout daily life) : more than 30 days
Chronic users (usage on a daily basis) : 1 to 2 weeks
Moderate users (four to seven days per week) : 5 to 7 days
Occasional users (up to three times weekly) : 3 days
Did you know that urine testing is the most common testing method?
If you are ever asked to take a blood test for marijuana, rest assured that it only really stays in your blood stream for up to two days in most cases. Sure, there are the outliers that will cite that it has been found after 25 days, but that’s a rarity and also coincides with chronic heavy use.
Once you inhale weed, it’ll be in your bloodstream in mere seconds as it’s already made it’s way to the tissues. Parts of it will be absorbed into your blood and broken down.
If you are ever sent to a laboratory to get a marijuana test, this is where they’d look for the weed. It’s not a very common type of testing.
You can actually have marijuana find it’s way into your saliva through the mere exposure to smoke, so be very careful of who you hang around leading up to a saliva test for weed. Of course, if you do smoke it, you’ll find that it’ll be detectable up to 29 days if you are a chronic user and just three days if you smoke occasionally.
Interesting Fact: if you find yourself in a jurisdiction where weed is legal, your oral fluid can be used for roadside sobriety testing. Keep that in mind before you go to Colorado or other legal States and just start smoking and driving, please.
This is the one you’ll want to really pay attention to. First off, because the hair test for marijuana is a common one. Secondly, and perhaps more importantly, because I’ve found a fool proof solution to the hair follicle testing that can help you beat it.
You’ll see marijuana use showing up in your hair tests for up to 90 days because the marijuana finds the hair follicles by coming through minute blood vessels.
When a hair follicle test is done, they will sample a 1.5-inch strand of hair plucked from the scalp to look at marijuana use over the last 90 days.
How Long Before the Marijuana Metabolizes?
We all understand that the active ingredient in marijuana is THC, right?
That should be basic knowledge, but I like to refresh things for people who may be learning about this for the first time. THC is short for delta-9 tetrahydrocannabinol. It enters your body and makes it’s way into the bloodstream. Some is stored for a while in fatty tissues and organs. Once it’s entered your kidneys, it can be reabsorbed into your bloodstream.
With over 90 metabolites, THC gets broken down in your liver. As I touched on earlier, most drug tests look for metabolites.
Over time, THC and it’s metabolites are pushed out of your system through your stool and urine.
What Determines How Long Weed Remains In Your System?
There are a few things that will come into play to help determine how long this will stay in your system.
Body Mass Index (BMI)
While these aren’t related to the drug, they all have a hand in processing the drug.
Of course, the number one factor is frequency. If you are a heavy user, and use a huge dose, obviously it’ll stay in your system a longer time versus the occasional use of a small dosage.
When you smoke a stronger weed with a lot of potency, it has the chance of staying in your system longer as well.
How You Can Speed up The Process
I already know what you are thinking, how can I make marijuana metabolize through my system faster?
Many blogs will tell you to steam out, sweat out the marijuana through exercise, drink water, and be healthy, but while those all help you naturally detox, it won’t necessarily push weed through your system any quicker.
The only way to really help the cause is to use a detox kit.
How Long Before You Feel the Effects of Weed?
Sort of unrelated, but have you ever thought of the time it takes to get high versus the time it takes to rid your body of weed and it’s metabolites?
I have always been curious as to how you can get high so fast, but can’t get weed out of your system for days, and often times, a month.
The average person gets high 15 to 30 minutes after smoking weed, and up to two hours after ingesting it.
What are the Short Term Effects of Being High?
enhanced well being
feeling of relaxation
time feels like it stops
feeling of humor and talkativeness
altered state of mind
While those affects deal with the “high” of weed, these ones are more like side effects that most people will agree aren’t enjoyable:
lack of focus
desire to eat more
hard to sleep
feeling of restlessness
increased heart rate
dry eyes and “cottonmouth”
Of course, in some situations people can go off the deep end and even hallucinate or become paranoid. Don’t worry, as the short term effects of weed will wear off in just one to three hours.
Weed stays in your system for a variety of time frames depending on many factors. If you are having to pass a drug test, it’s best that you stay away from marijuana entirely leading up to the test for 90 days. Of course, should you make a mistake, we recommend this vendor. They sell every type of kit you need to pass any test mentioned above, and even have at home drug testing kits you can use to test yourself prior.
WEDNESDAY, Jan. 9, 2019 — Many doctors may worry about giving their hospital patients a flu shot, but a new study suggests they can relax.
“We know rates of inpatient flu vaccination are low, often due to physician concerns that the vaccine could complicate healing or delay hospital discharge,” explained study author Sara Tartof, from the Kaiser Permanente Southern California department of research and evaluation.
“Our findings demonstrate that not vaccinating patients during a hospitalization may be a missed opportunity,” Tartof said in a Kaiser news release. “Right now, only 28 percent of patients not already vaccinated prior to hospitalization are being vaccinated before they leave the hospital.”
In the study, the researchers analyzed data from more than 250,000 patients, aged 6 months and older, who were hospitalized in a Kaiser Permanente hospital in Southern California during any of three flu seasons between 2011 and 2014.
People who received a flu shot while in the hospital had no increased risk of outpatient visits or hospital readmission within seven days after leaving the hospital. They also had no increased risk of fever or laboratory tests for infection, the findings showed.
The study also found that 74 percent of those weren’t vaccinated before or during hospitalization remained unvaccinated throughout the flu season.
The report was published Jan. 8 in the journal Mayo Clinic Proceedings.
Dr. Bruno Lewin is a family practice physician at the Kaiser Permanente Los Angeles Medical Center. He said, “This research backs up what many physicians have known intuitively for some time: Giving patients the flu vaccine while they are hospitalized is convenient and, most important, safe.”
So, Lewin added, “Unless there are contraindications, physicians should have no hesitation to vaccinate patients with the flu vaccine while they are hospitalized.”
Previous research has also found that surgical patients who received the flu vaccine during their hospital stay did not have increased risks of complications or delays in leaving the hospital.
In addition, the U.S. Centers for Disease Control and Prevention recommends that hospitalized patients who are eligible receive the flu vaccine before discharge.

SATURDAY, Jan. 20, 2018 — The growing popularity of snowboarding and skiing has meant more injuries on the slopes, a new review shows.
In 2015, more than 140,000 people were treated in U.S. hospitals, doctors’ offices and emergency rooms for skiing and snowboarding-related injuries, according to the U.S. Consumer Product Safety Commission.
Snowboarders are three times more likely than skiers to be injured. In 1989, snowboarding injuries accounted for 4 percent of all snow sport-related injuries, before rising to 56 percent by 1999, according to the review.
The review was published this month in the Journal of the American Academy of Orthopaedic Surgeons.
“Skiing and snowboarding are associated with a large number of injuries, with specific patterns and anatomic areas affected,” said study author and orthopaedic surgeon Dr. Brett Owens.
“While some injuries are unavoidable, many are caused by skiers and snowboarders exceeding their comfort zone in either speed or technical challenges on the mountain,” Owens said in a journal news release. “It is critical to stay in control and be prepared to slow and stop to avoid contact with another person on the slope.”
The most common skiing and snowboarding injuries are to the spine, pelvis, shoulders, wrists, hands, knees, feet and ankles.
“Snow sport athletes can best prepare for their sport with a general preseason conditioning program, as well as familiarity and maintenance of equipment,” said Owens, who’s also a professor of orthopaedic surgery at Brown University.
He added that skiers and snowboarders should: always wear a helmet; avoid alcohol and drugs; be extremely cautious in poor weather conditions; always obey signs and ski patrol instructions; and never ski out-of-bounds.
MONDAY, June 12, 2017 — As the first major heat wave of the season has much of the eastern United States sizzling, people need to take steps to prevent heat-related illnesses, an emergency doctor says.
Hot temperatures and high humidity are likely from the shores of New England through the Great Plains. Temperatures could reach into the 90s for days, according to The Weather Channel. In some areas, record high temperatures set in the 1800s could be broken, USA Today reported.
“It’s vital to drink plenty of cool fluids, and stay out of the sun during the mid-part of the day [10 a.m. to 2 p.m.] when the sun is typically the strongest,” said Dr. Robert Glatter, an emergency physician at Lenox Hill Hospital in New York City.
“Try to reduce exertion when the heat index climbs — conserve your energy,” he recommended.
“If you will be exercising in the heat for under one hour, make sure you drink cool water before you begin your exercise, as well as after you complete your workout. Under one hour of exercise, sports drinks and salt replenishment are generally unnecessary. That said, the heat index and humidity are important factors in your choice of ideal fluid,” Glatter said.
But if you’re planning to exercise in the heat and humidity for more than an hour, it’s important to consume a sports drink, in addition to water, to replenish the salt loss from sweating, Glatter said. “A few salty pretzels are also a good alternative to a sports drink if you prefer,” he added.
It’s best to stay indoors with air conditioning if possible. If air conditioning isn’t available, you can reduce your temperature by spraying cool mist on your skin and using a fan.
If you go outside, wear loose-fitting and light-colored clothing and a wide-brimmed hat. Put on sunscreen and reapply it every two hours while in the sun, Glatter said.
And never leave a child in a parked car in the summertime. “When it is 90 degrees outside, the temperature can climb to over 150 degrees in the car in as little as 15 to 20 minutes,” Glatter warned.
“Even when it is 70 degrees outside, the temperature can climb to well over 100 degrees in under 30 minutes. The windows in the car trap heat, almost like a greenhouse effect,” he said.
The ASPCA reminds pet owners that the same advice holds true for your furry companions: don’t leave them in the car. Even with the windows open a bit, a car can get dangerously hot, and dogs don’t cool themselves as well as humans do.
During any periods of high heat and humidity, keep a close eye on seniors and children because both are at increased risk for heat-related illnesses, Glatter said.
“Heat cramps and heat exhaustion are the most common heat-related illnesses. Nausea, dizziness and muscle cramping are most common with this condition. Skin may be cool and moist with profuse sweating,” he said.
Depending on how serious symptoms are, IV fluids may be necessary to help reduce the effects of heat. “A cool air-conditioned environment is also essential to help persons more effectively cool their bodies,” he said.
Heat stroke is even more serious than cramps or exhaustion, and is a medical emergency.
“Patients may develop temperatures up to 106-108 degrees, with confusion and disorientation, and loss of ability to produce sweat to cool the body. Cooling ice baths and misting fans can help reduce core temperatures,” Glatter explained.
“Typical medications such as ibuprofen and acetaminophen are not helpful with such elevated temperatures, and in fact may be harmful,” he said.
The U.S. Centers for Disease Control and Prevention has more on extreme heat.
SATURDAY, Feb. 11, 2017 — Before you head outside to shovel the snow off your sidewalk this weekend, heed some safety advice so you don’t slip on the ice and land in the ER.
It’s important to pay attention and take extra precautions while getting around, University of Illinois safety experts say. Even if snow has been cleared from sidewalks, parking lots and other public areas, there could still be patches of ice.
There are some steps you can take to prevent slips or avoid serious falls during winter. The university experts recommend the following:
Choose the right shoes. Avoid wearing boots or shoes with smooth leather or plastic soles and heels. Footwear made of non-slip rubber or neoprene with grooved soles provide some traction on snow and ice, and will reduce the risk of falling.
See and be seen. It’s important to stay warm on winter days, but don’t let hats and scarves prevent you from hearing and seeing what’s around you. Choose brightly colored or reflective outerwear to help ensure you are visible to drivers. It’s also important to wear sunglasses to reduce glare and avoid potential hazards. If you do slip, a heavy or bulky coat will help break your fall.
Proceed with caution. It’s a good idea to assume that any surfaces that look dark and wet are icy. Dew and water vapor tends to freeze on hard surfaces, creating a thin and invisible layer of ice. To avoid these slick areas, stay in designated walkways whenever possible. It’s not a good idea to opt for shortcuts through areas that haven’t been cleared of snow or ice. If necessary, walk on grassy edges along icy hills or sidewalks to avoid falling.
Stay balanced. Bending slightly and walking flat-footed with your arms out to your sides can help you avoid falling. Be mindful of heavy bags that could cause you to lose your balance. Try to lighten your load and keep your arms free. It’s also a good idea to keep your hands out of your pockets so you can break your fall if you slip.
Take your time. Walk slowly and with shorter steps in slippery conditions. This will give you more time to react and prevent a fall-related injury. Use hand railings and be extra careful getting in and out of cars or other vehicles.
FRIDAY, Jan. 27, 2017 — How many hours you devote to social networking, gaming and other online media may depend on your genes, British researchers report.
People differ significantly in their use of online media, and researchers are trying to determine why. This new study of twins gives DNA some of the credit.
Researchers at King’s College London analyzed online media use by more than 8,500 16-year-old identical and non-identical twins. Identical twins share 100 percent of their genes; non-identical twins share 50 percent of their genes.
The researchers concluded that genes, or heritability, accounted for more than one-third of the differences in use of online entertainment, gaming and educational media.
“Our findings contradict popular media effects theories, which typically view the media as an external entity that has some effect — either good or bad — on ‘helpless’ consumers,” first author Ziada Ayorech said in a college news release.
“Finding that DNA differences substantially influence how individuals interact with the media puts the consumer in the driver’s seat, selecting and modifying their media exposure according to their needs,” said Ayorech, who is in the college’s Institute of Psychiatry, Psychology and Neuroscience.
Environmental factors — namely, access to media devices — played a bigger role than genetics, however.
When the researchers looked at whether only one sibling had a smartphone or parents monitored one twin’s use of social networks more tightly than the other’s, they found such factors accounted for nearly two-thirds of the differences in online media use, the researchers said.
Although the study found a link between genes and online activity, it didn’t establish a cause-and-effect relationship.
The study was published Jan. 23 in the journal PLOS One.
