"With better temperatures you have more mosquitoes feeding more regularly and having a more threat of obtaining infection. and then the virus replicates faster as it's hotter, therefore the mosquitoes can transmit earlier of their life," stated entomologist invoice Reisen of the college of California Davis.

some sufferers broaden paralysis

some of Zika sufferers in Brazil have also advanced a unprecedented autoimmune condition referred to as Guillain-Barré syndrome, which can purpose as a minimum brief paralysis.

One survivor informed CBS news, "i used to be paralyzed, I could not stroll. All of my joints felt like lead weights."

This isn't always euthanasia, when a doctor gives a affected person a deadly injection. it's illegal in all 50 states. resource-in-loss of life, or what warring parties call "assisted suicide" and supporters call "loss of life with dignity," relies on human beings taking the medication themselves. Oregon have become the primary kingdom to legalize it 18 years in the past, however because a nurse or physician is not often gift, it's remained ordinarily a personal affair, practiced behind closed doorways. We desired to listen from patients and family contributors who have skilled it and are combating to make it legal nationwide.

Brittany Maynard had been married much less than a 12 months when the headaches commenced. This MRI discovered a lethal mass -- it turned out to be brain most cancers so competitive docs gave her best six months to stay.

[Brittany Maynard, CBS News interview: All evidence points to the fact that this cancer will kill me.]

three weeks earlier than she died, Brittany, bloated by medication used to manipulate brain swelling, defined in an interview with CBS news why she was grateful to find a prison way to cease her life.

Brittany Maynard: Being capable of take a medication that permits me to slip into a nap in five minutes and skip away maximum probably in the 1/2 hour sounds a lot higher to me simply as a human being, as a daughter, as a wife. and i think it sounded better to my own family than analyzing approximately the alternative.

The opportunity, husband Dan Diaz says, changed into for Brittany to undergo weeks of agonizing decline.

Dan Diaz: Brittany said, "i'm now not afraid to die. At this point i am not scared of death. but i am frightened of being tortured to loss of life."

Dr. Jon LaPook: What did she suggest by way of being tortured, mainly? What turned into she frightened of?

Dan Diaz: So those signs that she knew become coming for her, the torture for her would've been dropping her eyesight and no longer knowing now who's within the room. I imply, the seizures had been awful enough because it become.

Dr. Jon LaPook: How about pain?

Dan Diaz: pain become simply constant.

sudden cardiac arrest can also have warning signs and symptoms after all

surprising cardiac arrest, a lethal circumstance that occurs whilst the heart  stops beating, has long been a conundrum for coronary heart medical doctors. It kills more than 300,000 americans every year, and was generally believed to strike with out warning.

however a new take a look at inside the Annals of inner medication shows that surprising cardiac arrest might also have warning symptoms after all.

Senior writer Dr. Sumeet Chugh said their research, which blanketed 839 sufferers among the a long time of 35 and sixty five, determined that many sufferers revel in warning signs and symptoms inside the days or weeks before having a unexpected cardiac arrest.

"We used to think surprising demise occurs without caution, or little or no caution -- a couple of minutes or an hour," said Chugh, the clinical director of the coronary heart Rhythm center within the Cedars-Sinai heart Institute, and the Pauline and Harold fee Chair in Cardiac Electrophysiology studies.

Their look at made the unexpected discovery that about half of of patients who've a sudden cardiac arrest first revel in signs like intermittent chest pain and stress, shortness of breath, palpitations, or ongoing flu-like signs such as nausea and abdominal and returned pain.

yet eighty percent of them ignore their pre-arrest signs.

"when those signs and symptoms appear, in approximately 1/2 the people who have SCA [sudden cardiac arrest], the sizable majority don't act upon the signs, and that is very puzzling," Chugh informed CBS news.

He said those who did respond to the early signs and symptoms regarded to have a better final results than people who did not.

With surprising cardiac arrest, the pumping motion of the coronary heart stops, inflicting blood flow to the relaxation of the frame to forestall. it's far deadly approximately 90 percent of the time.

surprising cardiac arrest is different from a heart attack, Chugh stated, which occurs when there are blockages in the blood vessels that nourish your coronary heart. A heart attack can every so often cause an electrical disturbance that ends in sudden cardiac arrest.

"The diagnosis for unexpected cardiac arrest is sincerely dismal," said CBS news scientific contributor Dr. Tara Narula, a heart specialist at Lenox Hill sanatorium in ny. "It strikes people within the high of their life, across the age of sixty five. or even after they get better, many are left with neurological harm," including hypoxic mind damage from lack of oxygen.

"The maximum important component isn't always to reduce or ignore the signs," Narula said, "mainly if they're signs and symptoms like chest ache or shortness of breath, and in particular when you have danger elements for coronary heart sickness, which reasons 70 percent of cardiac arrest."

Chugh said a great deal extra research needs to be executed; they don't have sufficient records but to provide concrete prevention techniques the manner doctors have for, say, diabetes, wherein sufferers can take protective steps whilst caution symptoms and signs first start to appear.

but figuring out the caution signs and symptoms is an critical first step.

"this is bankruptcy one. We really want to send out the message that there is an opportunity here we never knew existed. We idea whilst SCA occurs, you name 911 and it is curtains for ninety percent of human beings. irrespective of how speedy we get there, on the maximum, we store 10 percentage of humans who have a cardiac arrest. there is no circumstance regarded to man wherein you have the risk of death within 10 mins," he stated.

"that is what human beings don't apprehend. As each minute is going by using, there may be a ten percentage less hazard of survival. If the paramedics get there in 10 minutes, you are gone."

Chugh stated the intention isn't to create panic about symptoms that could suggest some thing greater minor in most patients.

"All we are able to say very widely is, those who are acknowledged to have coronary heart sickness, in the event that they have sudden out-of-everyday signs and symptoms, they must are seeking for health care," and that a mixture of heart disease, genetic traits, and triggers are likely at play, he stated.

"This new studies suggests for a variety of human beings, not simplest can we have 4 hours however we might even have four weeks."

Colo. college students attend first pot-targeted education path

the scholars are seventh graders within the first pot-focused schooling route in Colorado, created through faculty counselor Molly Lotz and instructor Sarah Grippa, co-founders of the Marijuana education Initiative.

Its message to the kids -- that pot can harm your nonetheless-growing brain -- is crucial, Grippa said, and the students get that.

"you believe you studied they may be antique enough to mention or maybe to care, like, what's occurring to my mind?" CBS information correspondent Barry Petersen asked her.

"I suppose they're," Grippa said.

For over than 30 years, advertising campaigns and applications like DARE preached the risks of marijuana and other drugs. however in Colorado, pot is now criminal for recreational use through adults and may be prescribed by way of medical doctors as a remedy even for youngsters -- which leaves Colorado students surrounded by means of mixed messages.

"We nonetheless do have a couple mother and father here and there that... assume it is a little too early to start having the communique," very wellRidge superintendent Darci Mohr said.

but Mohr said that is when kids are starting to experiment.

"So between 5th and 6th grade is when we are starting to see that kids are really talking about it," Mohr said.

"you're virtually looking to be preemptive approximately this," Petersen said.

"Oh, definitely. We usually should live one step in advance of the children. if you don't, then you've misplaced the struggle," she said.

Pot training is supported proper up to the pinnacle.

"You cannot teach youngsters at too early an age. We see sanatorium visits -- plenty of the edibles that we are having troubles with -- medical institution visits are very young kids," Colorado Gov. John Hickenlooper stated.

Taxes on marijuana assist pay for the direction, and its cognizance is kept slender.

"we are now not imparting morality. we are just trying to provide reality-primarily based, technology- and studies-backed facts so that teenagers can try and navigate this very hard and new environment," Grippa said.

high times can mean confusing new instances for young human beings, and those instructors desire know-how can be a kid's quality protection.

Gov. Hickenlooper is expected to review a invoice this week that might permit a few students use medical marijuana products in colleges. The measure would require campuses to permit non-smokable marijuana drug treatments like oils and capsules, but best if the drug is supplied by way of a determine, guardian or scientific professional.

Does swaddling babies boost chance of SIDS?

If toddlers are swaddled at some point of sleep, their chance of demise from SIDS is better, specifically if they're positioned on their stomachs, new studies shows.

Swaddling is defined in various approaches, but it commonly refers to wrapping a child snugly in a blanket or cloth, with head exposed however fingers inside. Swaddling is concept to have a calming influence on babies that facilitates them sleep.

but, swaddling can be volatile, the brand new take a look at finds.

"toddlers who were swaddled were 50 to 60 percent much more likely to die of SIDS," stated lead researcher Dr. Rachel Moon, a professor of pediatrics on the university of Virginia faculty of medicine.

Moon's crew analyzed the results of 4 previously posted studies. The research spanned two decades and included regions of england, Tasmania in Australia, in addition to Chicago.

at the same time as the general SIDS danger changed into increased with swaddling, the risk was even greater when swaddled infants were located on their stomachs to sleep, Moon stated. those toddlers, compared to the ones now not swaddled, had about 13 times the risk of loss of life from SIDS, additionally known as sudden infant demise syndrome, she stated.

The chance also accelerated as infants approached 6 months of age, Moon stated, when they're possibly so as to roll over by means of themselves. most toddlers can try this by using round four months of age, she referred to.

Moon said she could not give an explanation for the hyperlink, and the study couldn't prove a motive-and-effect dating between swaddling and SIDS risk.

The evaluation also had a few boundaries, including the reality that swaddling was described in a different way within the four research.

SIDS killed approximately 1,500 youngsters within the usa in 2014, according to the U.S. centers for ailment manipulate and Prevention. it is the leading purpose of loss of life in toddlers below 1 12 months of age. it's miles described as a unexpected loss of life in an toddler that can not be explained after a thorough research, which includes an post-mortem.

in the research reviewed, 760 babies who died of SIDS were in comparison with 1,759 who did not.

The findings appear to support cutting-edge scientific recommendation to avoid setting toddlers on their stomach or facet to sleep, Moon stated.

"The take-home messages are, if the infant is getting older sufficient wherein they could roll, they shouldn't be swaddled," and that they shouldn't sleep on their stomachs or facets, Moon stated.

but, another professional sees a slightly distinct take-domestic message.

"I generally do not suggest swaddling to place them to sleep for the night time," said Dr. Gloria Riefkohl, a pediatrician at Nicklaus children's medical institution in Miami.

"I think swaddling should be executed [only with observation]," she stated. "Any swaddling need to be done with the toddler on your palms, or [while] gazing the child."

even if the child "co-sleeps" with the parents, Riefkohle does not propose swaddling for nighttime sleep in any respect.

60-12 months-antique is working example: "fitness has no age"

new york --Being in Ruth Hernandez's fitness magnificence, you can't assist however note she's bursting with electricity, short on her ft, and has a ardour for health.

One factor you now not won't wager right away? Her age. Hernandez is 60, but appears to have the stamina of a 20 12 months old. She credits a number of that to workout.

"It just gives you a lot electricity. i will wake up in the morning and, bing, I soar up," said Hernandez.

As human beings get older, muscular tissues, tissues and bone have a tendency to become worse and energy diminishes, a method that accelerates after age 50 or 60. however regular exercising "can definitely sluggish that deterioration," Metzl said. "It makes a large distinction for a way you age."

One thing medical doctors are getting to know extra about is the have an impact on of inflammation on a extensive range of illnesses.

"in case you exercise more than four to five times a week you have a good deal decrease levels of circulating infection on your body. So pretty a whole lot every sickness you may consider -- coronary heart ailment, diabetes, you call it -- is affected by persistent inflammation. And if you're exercising frequently it's lower," said Metzl.

"there is no drug this is as powerful and certainly to be had to each unmarried character as exercising. it really works for anyone, old and young alike," he brought.

Hernandez wanted to do some thing changed into within her manage to keep away from health troubles as she elderly. She decided around the time her mother handed away seven years ago that she was going to make health her lifestyle. Her mom had various health troubles, some of which Hernandez said could have been helped by being energetic and staying fit.

"She passed on and i decided I failed to need to be like that. I need to be healthy, healthy. not medical doctors. clinical-loose in each manner," stated Hernandez.

For the beyond 12 months, Hernandez has been coaching a health magnificence for a set of about 30 girls 3 days every week in Queens, ny, thru NYC Parks. She has labored with the branch for 17 years coordinating after-college leisure sports for youngsters. but she had a actual motivation to start helping human beings live match around her age. The ladies in the class are all over 50 and most are retired.

some of the girls instructed CBS information that in the event that they were not in Hernandez's class they would be bored, probably sitting home eating or looking tv. Many said coming to Hernandez's elegance has helped them feel stronger, each physically and mentally. they have got much less tension, more electricity, and revel in the experience of community.

Hernandez said the ladies have nicknamed themselves "The Divas." The ladies push every different to work tougher -- and do not forget themselves like a own family.

There is lots of advantage to running out as a collection, stated Metzl: "people are essentially social animals and they will work tougher and they will be a whole lot extra diligent with their exercise applications if they are in a set."

beyond motivating each different, the ladies locate proposal in just looking Hernandez. The feisty health instructor indicates no mercy as she demonstrates actions and sports with the institution. They squat, carry weights, and work muscle tissues Hernandez stated they wouldn't typically paintings.

It sure would not appearance a "senior health magnificence," and Hernandez makes it that way on motive. She said she desires to be an example "and let them know, 'listen, if i can do this you can do it, too.'"

Her hard-love approach has helped bring about modifications she has personally visible within the group. She has seen the girls come to be happier, have less again and joint ache, and develop extra assured.

on the end of class Hernandez and her college students dance it out, some with weights nevertheless in hand. Hernandez busts out a few dance moves herself, and steals some proud glances at the group round her inside the health club.

What you want to recognize approximately examine on folic acid and autism

a brand new examine indicates a probable hyperlink among high tiers of folic acid in pregnant girls and an improved chance in their children developing an autism spectrum disease.

but CBS news' Dr. Jon LaPook says some headlines had been deceptive, and pregnant girls ought to hold taking folic acid.

"there may be no question that ladies who have too little intake of folic acid for the duration of pregnancy have an expanded danger in having youngsters with severe neurological issues," Dr. LaPook said.

in line with LaPook, the document is still very initial, and loads greater desires to be studied.

"this does not imply that taking an excessive amount of B12 or folate causes autism, it is an affiliation," LaPook stated. "We do not want girls to misinterpret this headline."

Is an excessive amount of folic acid a motive of autism?

for many years, pregnant ladies and women who can also end up pregnant were cautioned to take folic acid to help prevent sure beginning defects.

however a new take a look at suggests it is able to be viable to get too much of an amazing thing -- very excessive levels of the vitamin in mothers' blood on the time of childbirth became related to higher risk of their children developing autism years later.

other studies points to an opposite dating between folic acid and autism, showing that good enough amounts of the nutrition on the time of idea can extensively reduce the danger.

certainly, a few experts raised questions on the brand new studies. They be aware the findings are initial numbers, and based totally on a small number of households seen at best one clinic.

also, the evaluation is based on measures of the vitamin in moms' blood on the time of transport, which might not display tons approximately what became going on inside the girls's body at the time of early fetal mind improvement.

Even the researchers themselves said there is no purpose to trade modern public health suggestions. "We are not suggesting anybody stop supplementation," stated one of the researchers, M. Daniele Fallin of Johns Hopkins university's faculty of public health.

CBS news' chief clinical correspondent Dr. Jon LaPook says a few headlines were misleading, and pregnant women need to preserve taking folic acid.

"there may be no question that women who've too little consumption of folic acid all through being pregnant have an multiplied threat in having kids with excessive neurological troubles," Dr. LaPook said.

in line with LaPook, the record remains very initial, and loads more wishes to be studied.

"this does not suggest that taking an excessive amount of B12 or folate reasons autism, it is an affiliation," LaPook stated. "We do not need girls to misread this headline."

however it increases an intriguing question that have to be explored in other research, Fallin stated. two outside experts agreed.

"it is a finding that has plausibility," said Dr. Ezra Susser, a Columbia university professor of epidemiology and psychiatry. He stated different researchers have puzzled whether or not an excessive amount of folic acid can purpose problems.

The findings were offered Wednesday at an autism studies conference in Baltimore.

Folate is a diet determined in foods that is critical in cell boom and improvement of the fearful device. A artificial version, folic acid, is utilized in dietary supplements and is used to support flour and cereals.

decades in the past, researchers located sure degrees of folic acid should prevent principal beginning defects of the child's brain and backbone. inside the early 1990s, U.S. health officers began recommending that all ladies who would possibly come to be pregnant must take 400 micrograms of folic acid every day. And in the overdue 1990s, federal guidelines started out mandating that folic acid be brought to flour, bread and other grain merchandise.

those steps are considered one of the first rate public fitness fulfillment testimonies of the remaining 1/2-century. officials estimate that 1,000 beginning defects are avoided each year because of it.

the brand new researchers followed 1,391 children who had been born at Boston university medical center in 1998 via 2013. about a hundred of them have been later diagnosed with an autism spectrum ailment.

The researchers went back and looked at degrees of folate and vitamin B12 in the blood of the children's moms at the time of childbirth. They observed that sixteen of them had very high degrees of folate, and 15 had extraordinarily excessive tiers of nutrition B12.

those are very small numbers of instances. but they constitute extensively higher proportions than had been visible in mothers whose children who didn't increase autism.

If both tiers are extraordinarily high, there is more than a 17-fold greater danger that a child will expand autism, the researchers stated.

maximum of the moms inside the observe said they took multivitamins -- which would encompass folic acid and nutrition B12 -- for the duration of their being pregnant. but the researchers say they do not know why a few girls had such excessive degrees of their blood.

it may be associated with taking too many supplements and ingesting too many fortified meals. Or there will be a genetic reason that brought about a few girls to soak up greater folate than others. Or there could be a combination, they said.

Many studies of autism recognition largely on white youngsters in middle- and top-income households. This one drew specifically from low-income and minority households, the researchers noted.

suppose you're allergic to penicillin? you'll be incorrect

Many those who accept as true with they're allergic to penicillin really aren't, an allergist says.

"allergy reactions are the main trouble within the use of penicillin," said Dr. Thomas Leath, an allergist with the Texas A&M college of medication.

"Many folks that document a penicillin allergic reaction do not even recognise why. it can be due to the fact they'd a reaction once they were very young, or because a family member had an hypersensitivity and informed their kids not to take penicillin," he stated in a college news launch.

individuals who are allergic to penicillin often must take extra pricey antibiotics which could have greater side results, Leath cited.

at the same time as many human beings inform their medical doctor they are allergic to penicillin, a Mayo hospital observe observed that 80 percentage to ninety percent of people who listing a penicillin allergic reaction have no evidence of a true response and keep away from the drug unnecessarily. there may be a skin test for penicillin allergic reaction.

some other cause why humans mistakenly believe they're allergic to penicillin is beside the point prescribing of the drug for conditions it can not treat, which include the flu and colds.

"Penicillin will now not treat viruses like the common cold. while someone is prescribed an antibiotic for an endemic, they'll get away in a rash or revel in other aspect outcomes falsely attributed to penicillin," Leath stated.

A real hypersensitive reaction to penicillin can cause symptoms that consist of hives, nausea, diarrhea, vomiting, swelling of the lips, tongue and throat, and asthma-like signs and symptoms, he said.

"Penicillin hypersensitive reactions can even drop your blood stress, cause dizziness or loss of awareness," Leath stated.

in case you enjoy nearly all of the signs indexed, and on the same time, you are having an anaphylactic [life-threatening] reaction and need to peer a fitness care issuer at once.

"real allergies manifest quick after publicity -- generally inside 10 to fifteen minutes or inside an hour or  of taking the drug. when you have a reaction, like an disenchanted belly, three days after starting a penicillin regimen, you in all likelihood are not allergic," Leath stated.

health practitioner who survived cancer, stroke: "i was there... maybe i can assist"

Ever for the reason that she changed into a little lady developing up within the small town of Rougemont, North Carolina, Cejas knew she desired to be a health practitioner. She earned degrees in biology and physics, a masters degree in public health, got her M.D. from The Howard college college of medicine and did a residency in general pediatrics at Tulane university.

It changed into at some point of her 2nd 12 months of residency that Cejas observed a lump forming on the right aspect of her neck. She notion it is probably a minor contamination and took antibiotics, but they failed to assist. Her med faculty colleagues and doctors instructed her no longer to fear. "Med college students are hypochondriacs," she notion, however something failed to sense right. a few days she turned into light headed and started getting awful headaches. She even fainted multiple instances. subsequently she pressed her primary health practitioner for a CT scan.

The scan confirmed a carotid frame paraganglioma -- a rare form of tumor that bureaucracy close to the carotid artery in the neck. In may of 2012, she had surgical treatment to remove the tumor. "It wasn't a idea that it may be most cancers," Cejas says. "It become a notion that i have this tumor and i should get it out and i am going to have this unsightly scar and that is the end of it."

while Cejas returned some days after surgical treatment to have her stitches removed, docs informed her the tumor became cancerous. It had metastasized to close by lymph nodes and Cejas wished a second surgery -- known as a modified radical neck dissection -- to get rid of the lymph nodes and other tissue under the pores and skin from the right facet of her neck.

"[When] you ultimately recognize what a cancer diagnosis certainly means... you get unhappy, you are burdened, it's lots of anger," says Cejas. "I may want to apprehend it due to the fact i've the clinical background, however it is one factor to know what something is objectively and it's every other issue to ought to address it yourself."

the second one surgery would go away her with a extra outstanding scar, and he or she'd want to move in for regular checkups -- however as soon as the method changed into over, Cejas thought the hardest part of the most cancers enjoy would be at the back of her.

On July 3, 2012, her health practitioner became almost finished with the neck dissection system when he observed her carotid artery became, as he defined it later, "leaky." whilst the health care provider attempted to repair the vessel it fell apart. Vascular surgeons had been known as in but they had been not able to restore the artery and rather installed a graft, or artificial blood vessel. Cejas wakened from the surgical procedure feeling groggy but otherwise first-class.

Later that night, she began to experience confused and indignant. "I don't have a motive to be [angry]," she recalls questioning. "i'm not absolutely in ache, this doesn't make experience... then things form of get hazy from there."

a touch after nighttime on July 4, 2012, Cejas started having a stroke. She changed into rushed to emergency surgery in which doctors found the artery graft had clotted, restricting blood drift to a part of her mind.

This time whilst Cejas awakened, the left aspect of her frame changed into paralyzed. She could not flow her left arm or leg. The side of her face changed into drooping. She could not devour or maybe swallow.

After a surgery, a most cancers analysis, a 2d surgical treatment and a stroke -- Cejas' life had been turned the other way up. just weeks before she were operating grueling 15-hour shifts as part of her residency. Now, she had start re-mastering simple features. She took her clinical know-how, and the dedication that helped her achieve a lot as a health practitioner, and centered it on restoration.

She began intensive remedy at once. within seven days of her stroke, she should flow her left leg, shoulder and wrist. After two weeks she became able to consume and swallow. Her speech got clearer after a month.

Now, she's able to walk, talk and devour commonly. And at the same time as her left hand will usually be slightly impaired, she would not note other symptoms of her stroke until she gets very tired or ill. however the revel in is always with her. "it is each day I take into account that I had a stroke," she says. "it's only a little bit much less frequent now than it turned into earlier than."

A latest MRI confirmed Cejas is likewise most cancers free. Her excessive scientific issues a transient hurdle to overcome as she continues her already staggering career.

She remained in her residency application at Tulane, completing it in 2013, and is now a second-year fellow inside the baby neurology education application on the college of Chicago. all through the first year of her fellowship, she frequently worked with grownup stroke sufferers. lots of them had signs and symptoms similar to her own. She says she's greater knowledge with all of her sufferers than she was. She knows what it's want to be in that bed. She knows how tough it can be. and he or she knows what it takes to get better.

"it may be very overwhelming on occasion to think about all of this stuff that befell," Cejas says. "And now and again managing these patients it puts me proper again there. but I ought to kind of step again and say, 'this is adequate. i was there, now i am not. permit me get you to where i'm. maybe i can help.'"
