TEN RECOMMENDATIONS FOR PREVENTING CANCER: WORLD CANCER RESEARCH FUND SAYS THIS IS WHAT YOU CAN AVOID DOING AND EATING TO LOWER RISK OF CANCER EXPERT



TEN RECOMMENDATIONS FOR PREVENTING CANCER: WORLD CANCER RESEARCH FUND SAYS THIS IS WHAT YOU CAN AVOID DOING AND EATING TO LOWER RISK OF CANCER EXPERT PANEL COMES DOWN HARD ON PROCESSED MEATS HOT DOGS BACON


The Anti Cancer Report Created by an Expert Panel Gives a Thumbs Down to Processed Meats and Salt, Ham, Bacon, Pastrami and Salami, as well as Hot Dogs and Sausages





A study released by the American Institute for Cancer Research (AICR) says that excess body fat as well as consumption of alcohol, red meat and processed meats like bacon, hot dogs and so on increase your risk of developing cancer".














  • Limit consumption of red meats (such as beef, pork and lamb) and avoid processed meats.(they say to stay away from things like hot dogs and bacon)
    "To reduce your cancer risk, eat no more than 18 oz. (cooked weight) per week of red meats, like beef, pork and lamb and avoid processed meat such as ham, bacon, salami, hot dogs and sausages."

    "Red meat refers to beef, pork and lamb, - foods like hamburgers, steak, pork chops and roast lamb. The term processed meat refers to meats preserved by smoking, curing or salting, or by the addition of preservatives. Examples include ham, bacon, pastrami and salami, as well as hot dogs and sausages.



    "The evidence from the Expert Report that red meat is a cause of colorectal cancer is convincing. This evidence is much stronger now than it was in the mid-1990s. Red meat contains substances that are linked to colon cancer. For example, heme iron, the compound that gives red meat its color, has been shown to damage the lining of the colon.Studies also show that people who eat a lot of red meat tend to eat less plant-based foods, so they benefit less from their cancer-protective properties".



    There is also convincing evidence that choosing processed meat increases the chances of colorectal cancer. The expert panel advises limiting red meat and avoiding processed meat. Studies show we can eat up to 18 ounces a week of red meat without raising cancer risk. Research on processed meat shows cancer risk starts to increase with any portion.



    "When meat is preserved by smoking, curing or salting, or by the addition of preservatives, cancer-causing substances (carcinogens) can be formed. These substances can damage cells in the body, leading to the development of cancer".




  • Be as lean as possible without becoming underweight.

  • Be physically active for at least 30 minutes every day.

  • Avoid sugary drinks. Limit consumption of energy-dense foods (particularly processed foods high in added sugar, or low in fiber, or high in fat).

  • Eat more of a variety of vegetables, fruits, whole grains and legumes such as beans.



  • If consumed at all, limit alcoholic drinks to 2 for men and 1 for women a day.

  • Limit consumption of salty foods and foods processed with salt (sodium). (You will be shocked when you look at a food label of some processed foods and see how much sodium they contain)."Consuming too much salt can be harmful to our health, increasing our risk of stomach cancer as well as high blood pressure".



    Our daily intake of salt should be less than 2,400 milligrams. We actually need much less than this. Most people in the Untied States currently consume more than 2,400 mg, but there are simple ways to cut down on our intake.



  • More About High Salt Sodium Intake at healty medical Blog



    "The Expert Panel found that salt and salt-preserved foods probably increase the chance of developing stomach cancer. Studies have shown that high salt intakes can damage the lining of the stomach. This is one way in which it might increase the risk of stomach cancer".



    "Most of the salt in our diets comes from processed foods. We are not always aware that these foods are high in salt because they may not taste ‘salty,’ so make sure to read the sodium content on the Nutrition Facts label. Watch out for breakfast cereals, bread, frozen meals, pizza and chips. Also, check the amount of sodium in canned products, such as soups and sauces, and avoid processed meats. Even sweet foods like cookies can contain high levels of salt".



  • Don't use supplements to protect against cancer.

    Special Population Recommendations

  • It is best for mothers to breastfeed exclusively for up to 6 months and then add other liquids and foods.

  • After treatment, cancer survivors should follow the recommendations for cancer prevention.

  • And always remember – do not smoke or chew tobacco.


  • Put down the Bacon! Report Emphasizes Cancer-fat Links

    PENICILLIN:WHO INVENTED PENICILLIN HOW PENICILLIN WAS DEVELOPED WHO CREATED AND MADE PENICILLIN FLOREY FLEMING CHAIN


    How A Cantaloupe in Peoria Led to a Fruitful Discovery.The Manufacture of Penicillin Had More Twists and Turns Than A Six Flags Roller Coaster








    In March,1942, a 31 year old woman, Anne Miller,lay in a New Haven,CT hospital dying of blood poisoning subsequent to a miscarriage. Her temperature swung between 103 and 106 for weeks.Nothing was able to control the strepococcus that had infected her blood.Her doctor felt like he was running out of options when he recalled a conversation with another doctor who spoke of work on an almost unknown substance called penicillin.
















    That substance, a bacteria killer, seemed the woman's last chance.A round of phone calls resulted in getting some of the precious penicillin for the woman.Within one day, the woman who had high fever for weeks had none.



  • Anne Miller, First Patient Who Was Saved by Penicillin


    "Although Sir Alexander Fleming, the Scottish biologist, was the first to recognize the therapeutic potential of penicillin through a chance discovery at St. Mary's Hospital in London in 1928, nearly a dozen years passed before scientists fully appreciated its significance and were able to produce it for experimental use in humans. Largely forgotten, it came to the fore only when researchers picked up on it again at Oxford University at the outbreak of World War II."

    "Before Mrs. Miller's doctors succeeded in saving her life, only a few experiments had been conducted with penicillin in mice and people, with results mixed and largely disheartening".




    Eric Lax unfolds the amazing story of the discovery and development of penicillin in his book "The Mold in Dr. Florey's Coat". The publisher is Henry Holt and Company.


    Penicillin easily qualifies as a wonder drug, having saved countless millions from a horrible fate. Steven Speilberg, in scouting for movie material would be hard pressed to find a more fascinating assortment of characters, action and human interest. Everything from an Einstein look alike Jewish refugee from the Nazis to a young woman saved at the last minute by the miracle drug to the search for ways to manufacture penicillin that led to a cantaloupe in Peoria, Illinois.



  • Fun Facts About Fungi

    From that first serendipitous moment when Alexander Fleming noticed that a mold in his lab could stop bacterial growth the story of penicillin has taken more twists and turns then a roller coaster.


    Alexander Fleming noted that something in a mold growing on a dish in his lab could kill bacteria but he wasn't able to isolate what that "something" was. He stopped working on the problem. Several people tried to isolate the antibacterial agent but penicillin languished until others came along and did the heavy lifting.


    It would be left to a number of scientists including a refugee from the Nazis who resembled Einstein,named Ernst Chain , an Oxford scientist named Howard Florey and Norman Heatley to assemble the puzzle pieces and make penicillin a life saver.



  • Ernst Boris Chain

  • Howard Florey

    Rubbing Mold In Their Coats To Escape the Nazis


    The Second World War gave a new impetus to the search for penicillin. Chain had been driven to England by the war. The scientists at Oxford who worked on the problem were concerned about an imminent German invasion. As a result they prepared to destroy their research lest it fall into enemy hands but they had a plan to save Penicillin. They rubbed Penicillin mold spores in their clothes so that those who might escape could carry it to a new land and proceed. Luckily, they never had to flee England but the search for methods of mass production led to America and a lab in Peoria,Illinois. U.S. Army Transport Command flew mold strain samples from all over the world to a laboratory in Peoria in a search for the best growth medium for penicillin. Amazingly it turned out that the mold strain that was most powerful was on a cantaloupe from a market in Peoria.

    WHAT SHOULD I DO ABOUT THE MEDTRONIC IMPLANTABLE DEFIBRILLATOR AND WHAT IS AN IMPLANTABLE DEFIBRILLATOR


    WHAT SHOULD I DO ABOUT THE MEDTRONIC IMPLANTABLE DEFIBRILLATOR PROBLEM AND WHAT IS AN IMPLANTABLE DEFIBRILLATOR





    It sounds like a cliche but things that were hardly dreamed of in the not so distant past have come to exist at the intersection of technology with medicine. I doubt if any doctor in the 1950's ever dreamed of a miraculous device such as the implantable defibrillator. When it senses a dangerous electrical rhythm in the heart the defibrillator delivers a life saving jolt of electricity.






    Video from the FDA About Sprint Fidelis Recall Click the Arrow to Start










    "Two months after Medtronic warned doctors and nearly a quarter-million patients that a wire, or lead, connecting their electronic defibrillators to their hearts might break, a 48-year-old patient had the lead and defibrillator removed and replaced. He described his fears and agreed to let a reporter observe the procedure on the condition that his identity remained private."

"The wire connects the heart to a defibrillator, a device that shocks faltering hearts back into normal rhythm. The company is urging all of the estimated 235,000 patients with the Fidelis, to see their doctors to make sure it has not developed a fracture that can make the device to misread heart-rhythm data.

    WHAT CAN I DO TO PREVENT METHICILLIN RESISTANT STAPH AUREUS INFECTION


    WHAT CAN I DO TO PREVENT METHICILLIN RESISTANT STAPH AUREUS MRSA INFECTION


    MRSA Antibiotic Resistant Bacteria Staph aureus is again in the news some common sense steps to lower chance of infection with Staph aureus and bacteria in general






    How can you lower the chances of MRSA Staph Aureus infection? The 64 million dollar question. It's all over the news, what you ask, is happening? Methicillin is a form of penicillin antibiotic that has been used to treat bacteria such as staphylococcus aureus infections that are resistant to regular penicillins.

















    Methicillin was kind of a second line of defense aginst these bacteria, sort of a second line of trenches for the enemy to cross. But bacterial strains have developed that can resist methicillin, the so called MRSA, methicillin resistant staph aureus. Staph aureus is very common, it is found on the skin.



    Staph has been around for a long time but now we are hearing more about the resistant staphylococcus. So what can you do to lessen your chances of getting staph? (and of course other bacterial infections).













  • Don't ignore a seemingly minor cut or scrape, get medical attention

    "To avoid transmission, the Center for Disease Control recommends

  • frequent hand-washing
  • showering after exercise
  • covering cuts and abrasions with bandages until healed
  • not sharing personal items like razors and towels that come into contact with bare skin
  • placing barriers between skin and shared equipment like weight-lifting benches
  • sanitization of frequently touched surfaces".

    "Perhaps the greatest threat posed by MRSA is its ease of transmission. MRSA can pass from person to person through simple touch, or the sharing of personal objects. It can navigate its way into the body through breaks in the skin, even microscopic ones, and through nasal passages.



    "Not surprisingly, community outbreaks have occurred in places where people gather in close quarters and where they may have physical contact, like schools, prisons, military barracks and storm shelters".

    Some settings have factors that make it easier for MRSA to be transmitted.

  • These factors, referred to as the 5 C's, are as follows: Crowding, frequent skin-to-skin Contact, Compromised skin (i.e., cuts or abrasions), Contaminated items and surfaces, and lack of Cleanliness.



  • Locations where the 5 C's are common include schools, dormitories, military barracks, households, correctional facilities, and daycare centers.

    GAMES AND ONLINE VIDEO GAMES DESIGNED TO HELP PEOPLE REDUCE AND COPE WITH STRESS INCREASE SELF CONFIDENCE

    GAMES AND ONLINE VIDEO GAMES DESIGNED TO HELP PEOPLE REDUCE AND COPE WITH STRESS


    VIDEO GAMES that lower stress increase confidence lower anxiety: Game to find smiling faces and get happier? People with lower self esteem focus on negative







    I like this computer game where you are presented with pictures of many people and you have to find the faces that are smiling. It's not as simple as it sounds.








    It's quite rapid. It certainly focuses your attention. You can try it for free at the MindHabits web site (see below). Researchers at McGill University say that online and video games where you find a smiley face can help reduce stress and increase confidence.
    "The McGill research team has developed the MindHabits Trainer game, in which one exercise shows a grid of faces, with 15 of them frowning and one smiling.The player must find the smiling face as quickly as possible."It's harder than it sounds," said McGill psychology professor Mark Baldwin, who led the team.





    Speaking about the computer games for stress. "Our starting point is past research showing that insecurity feelings and daily stress arise, in large part, from anxieties about whether one will be liked, accepted, and respected by one's peers and significant others .Sometimes people are aware of these concerns, but often social insecurities of this type influence people's thoughts and feelings "automatically", without a lot of deliberate thought and sometimes even entirely outside of their awareness. All they experience are negative reactions to the self or to social situations".









    The idea is that through repetitive playing, the mind is trained to focus on the positive aspects of life.



    In a field test, a sample group of telemarketers was asked to play the game everyday for a week just before their shift. A control group spent five to 10 minutes playing another game, without smiling faces, before their shift started.



    At the end of the week, the group that played the "find the smile" exercise reported feeling less stressed, had higher self esteem, made more sales, and were rated as being more confident in their phone calls. Most remarkably, said Balwin, they had 17 percent lower levels of the stress hormone cortisol".



    As they write in the blog Mindhabits "I urge you to get a copy of the October 2007 issue of the prestigious Journal of Personality and Social Psychology. There you’ll find our lab’s latest findings on how specially-designed videogames can help people cope with stress".



  • Playing social-intelligence game reduces stress hormone by 17 percent


    "This five-study project was part of my former graduate student Stéphane Dandeneau’s PhD dissertation at McGill University. The findings have been generating a lot of interest, so I’d like to summarize them here".



    "We wanted to see if specific patterns of social information processing might contribute to stress; if these patterns could be changed with the help of specially-designed computer games; and if the development of new habits of thought might lead to lowered stress levels in day-to-day life".



    "To make a long story short, whereas people with lower self-esteem tended to show a pronounced attentional bias toward threat, this tendency was essentially removed if they first played the find-the-smile game. This suggests that attentional habits can indeed be trained by practicing the ability to orient toward positive and away from negative social feedback".

    Managed Health Care... Here I come!

    Some news! I've packed in the stethoscope & otoscope. Handed the snotty noses over to someone else. And have moved into managed healthcare. Hot damn! What a rush!

    It's sad to be leaving some of the patients - who I really liked. I realised the other day how much of an influence I had (all Doctors have) in some people's lives. I'll miss hearing about the progress. And when I say progress, I don't mean medical. Who got their drivers license, picked a school for their kids or got the job they'd been hunting for size months. You get close.

    But we must move on. Doing:

    A) What makes us happy

    B) What challenges us

    C) Something which allows us to make the most impact.

    Sometimes I felt like I was wheelspinning in General Practice. Now, I have a chance to affect the bigger picture. And that thrills me.

    More on the job later... Give me a while to settle in, and I'll have some controversial views as usual. I must say... It's interesting to be "on the other side". I've been screamed at by no less than 10 doctors in the first week. I'm usually the one doing the screaming.

    NIGHT CONTACT LENS TO HALT NEARSIGHTEDNESS MYOPIA POSSIBLY IN CHILDREN





    CONTACT LENSES TO SLOW DOWN OR STOP NEARSIGHTEDNESS ESPECIALLY IN CHILDREN


    Optometrists Are Fitting Children and Adults With Contact Lens to Wear At Night To Try and Reshape the Eye Possibly Slowing Down or Halting Myopia





    A contact lens worn at night is being studied for a possible ability to reshape the cornea of the eye. Possibly slowing down nearsightedness, myopia, if the reshaping becomes permanent. But the technique is not without controversy.




    "Nearsightedness is caused by a steepening of the cornea, the transparent tissue in front of the colored part of the eye. Night time contacts apply a slight pressure to the center of the eye, flattening the cornea."




  • Watch Videos Explaining Night Contact Lenses to Correct Vision




    "Adult users must wear the lenses every night, or their corneas will revert to their original shapes, and nearsightedness will return.In children, however, a few small studies suggest the reshaping benefits might be permanent". There are possible problems, indeed all contact lenses wearers have to be very cautious. There is a recent report of problems in Taiwan.

    IS IT BELLS PALSY OR SOMETHING ELSE? ONE SIDED FACIAL PARALYSIS IS OFTEN BELLS PALSY BUT NOT ALWAYS


    Although One Sided Facial Paralysis is Often Bells Palsy Sometimes It Isn't As This Man Learned the Hard Way






    Bells Palsy is common.The sudden problem smiling or closing an eye on one side of the face happens to an estimated 40,000 people in the U.S. annually. Dr. Bell described it in 1882 yet Bells Palsy is still somewhat mysterious. Bells can be scary but it usually has a good outcome with treatment. You need to see a doctor pronto. Bell's palsy is a form of temporary facial paralysis resulting from damage or trauma or inflammation to one of the facial nerves. There is evidence of a virus causing Bells Palsy possible reactivated herpes.



  • Bells Palsy Interactive Tutorial

    Symptoms of Bell's Palsy


    Symptoms include:


  • twitching, weakness, or paralysis
  • drooping eyelid or corner of the mouth,drooling
  • dry eye or mouth, impairment of taste
  • excessive tearing in the eye.




    You and your doctor shouldn't always assume that facial paralysis is Bell's Palsy. The newspapers carried a story about a man who had facial paralysis. He went to several doctors who thought he had garden variety Bells Palsy. When things didn't improve other doctors determined that he had a tumor pressing on a facial nerve. He needed surgery to correct the problem.

    MicroRNA and CANCER METASTASIS





    The most lethal property of cancer cells is that they grow and spread from one location in the body to another. The cancer cell spreading is called metastasis. What makes cancer cells grow and why do cancer cells spread? Robert Weinberg and friends have spent a lifetime asking that question. It's the one trillion dollar question. People who unlock the secrets of cancer growth and metastasis(cancer cells spreading from one area to another) will have solved the greatest mystery in medicine and saved millions of lives.

    Newsweek had a fascinating article about how cancer research is done and what works in cancer treatment or at least produce more practical results. And also how some things in science and medicine are sometimes decided in decidedly unscientific ways. According to the article, "there is no more common refrain among critics of how the war on cancer has been waged than that innovative ideas, ideas that might be grand slams but carry the risk of striking out, are rejected by the National Cancer Institute in favor of projects that promise singles...Part of the answer is that the infrastructure of cancer is to keep things moving along as they have been and to reward people doing safe research."

    MAMMOGRAMS: DIAGNOSTIC AND SCREENING MAMMOGRAMS. A CLEAR EXPLANATION OF MAMMOGRAMS IN A BLOG BY A SURGEON AND WHAT ABOUT AN MRI




    Mammograms.Do you know the difference between a screening and diagnostic mammogram? For a test that is supposed to clarify things, the whole topic of mammograms and what they are used for is rather opaque.



    "Mammography can show changes in the breast up to two years before a patient or physician can feel them. Cure rates are much higher when the breast cancer can be found at this stage. Current guidelines from the U.S. Department of Health and Human Services (HHS), the American Cancer Society (ACS), the American Medical Association (AMA) and the American College of Radiology (ACR) recommend screening mammography every year for women, beginning at age 40".



    "The National Cancer Institute (NCI) adds that women who have had breast cancer and those who are at increased risk due to a genetic history of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and about the frequency of screening"

    .

    "Diagnostic mammography is used to evaluate a patient with abnormal clinical findings such as a breast lump or lumps that have been found by her or her doctor. Diagnostic mammography may also be done after an abnormal screening mammography in order to determine the cause of the area of concern on the screening exam".



    Video about Recommendation for MRI for Breast Cancer Click the Arrow










    What is a screening mammogram?



    A screening mammogram is an x-ray of the breast used to detect breast changes in women who have no signs or symptoms of breast cancer. It usually involves two x-rays of each breast. Mammograms make it possible to detect tumors that cannot be felt. Mammograms can also find microcalcifications (tiny deposits of calcium in the breast) that sometimes indicate the presence of breast cancer.


    How are screening and diagnostic mammograms different?



    A diagnostic mammogram is an x-ray of the breast that is used to check for breast cancer after a lump or other sign or symptom of breast cancer has been found. Signs of breast cancer may include pain, skin thickening, nipple discharge, or a change in breast size or shape. A diagnostic mammogram also may be used to evaluate changes found during a screening mammogram, or to view breast tissue when it is difficult to obtain a screening mammogram because of special circumstances, such as the presence of breast implants. A diagnostic mammogram takes longer than a screening mammogram because it involves more x-rays in order to obtain views of the breast from several angles. The technician may magnify a suspicious area to produce a detailed picture that can help the doctor make an accurate diagnosis.

    CHICAGO MARATHON: WHAT TO WATCH OUT FOR WHEN RUNNING OR JOGGING IN THE HEAT: BRUTAL CHICAGO MARATHON TEACHES PEOPLE EXERCISE STREET SMARTS




    WHAT TO WATCH OUT FOR WHEN RUNNING OR JOGGING IN THE HEAT: BRUTAL CHICAGO MARATHON TEACHES PEOPLE EXERCISE STREET SMARTS






    Forty five thousand people signed up to race in the Chicago Marathon 2007. Only 35,000 of the masses that had converged on Chicago from the four corners of the Earth actually started. As the wail of ambulance sirens filled the air it soon became apparent that this Marathon was going to be different. A new entrant in the Marathon would throw a wrench in the works. She was Mother Nature.



    The October Marathoners were confronted by a record combination of heat and humidity for which many were not well prepared.




    The Chicago Tribune wrote "As athletes work harder, blood that should be sent to the skin's surface to cool through sweating is instead used to keep the muscles working, said Mark Gorelick, assistant professor in San Francisco State's Department of Kinesiology. This leads the body to sacrifice its ability to reduce its core temperature". ( A doctor at a downtown ER said he had seen a Marathon patient with a core temperature of 107 degrees).



    "There are three major heat illnesses: heat cramps, heat exhaustion and heatstroke. Dehydration is the main culprit".




    "HEAT CRAMPS cause sharp, stabbing pain and muscle aches, said Terry Vanden Hoek, associate professor in emergency medicine at the University of Chicago.HEAT EXHAUSTION is characterized by dizziness, fatigue, nausea, vomiting, headache and signs of confusion. When the body reaches the most severe level, HEATSTROKE, its cooling mechanism has shut down, Vanden Hoek said. The body temperature reaches 103 or 104 degrees, which can cause seizures, loss of consciousness, coma, cardiac arrest and death".

  • MANY CAUGHT UNPREPARED: IT FELT LIKE AUGUST BUT RUNNERS DIDN'T PREPARE FOR HEAT


    Trying to make up for lost body fluids during running people can actually over drink water and dilute their blood. This can result in HYPONATREMIA (low sodium level in the blood). The concentration of sodium in the blood falls below normal levels. This is called dilutional hyponatremia. Syptoms of hyponatremia include:
  • headache
  • confusion and fatigue
  • stomach aches
  • swelling

    "A practical approach is to focus on the things you would like to do anyways. We compiled a list of fun things you can do, which generally seem to be good for the brain. Remember that this is not comprehensive - there are other components critical to a healthy lifestyle - but these are some pain-free ways to brain gain".

    WHAT ARE SHINGLES HOW DO YOU TREAT SHINGLES AND A VACCINE FOR SHINGLES


    WHAT ARE SHINGLES HOW DO YOU TREAT SHINGLES AND A VACCINE FOR SHINGLES




    You get an itchy even painful rash on your back. You think maybe you scratched yourself or something bit you. You look in the mirror and you see that on one side of your back you have a line of blisters and a rash along the line. Welcome to the wonderful world of Shingles.





    What are Shingles?



    Shingles is a common name for a rash caused by the Chickenpox virus, a.k.a Herpes Zoster aka Varicella. Frequently the rash arises on one side of your body and seems to follow a line. This is because the Chickenpox virus is inside the nerves under the skin. When the Shingles "erupt" they follow the lines of the nerves.







    Wow! Do I have Herpes?



    Not all Herpes are the same. When people hear the word "herpes" they immediately focus on sexually transmitted disease. There is a big group of viruses called herpesviridae. Herpes Zoster(also called Varicella Zoster)and Herpes Simplex both belong to herpesviridae. But Herpes Zoster is not Herpes Simplex which is associated sometimes with an s.t.d..




    What is the Big Deal About Shingles Anyway?




    1.Well for one thing, the pain can definitely get on your nerves. (excuse the pun).It can be experienced as itching,numbness,tingling,etc.
    2.A Herpes outbreak on the face is a medical emergency since if involves the eye it can damage vision.
    3. Untreated Shingles can lead to Post Herpetic Neuralgia. This is a syndrome of intense pain and discomfort.

    How do they treat Shingles?

    Shingles is treated with anti virus medicines. It is important to start the anti viral treatment as soon as possible after the start of Shingles. Zovirax and Valtrex are two frequently used medications for Shingles.



    I have heard there is a vaccine for Shingles What about the vaccine?



    First of all, if you already have Shingles you need the medication for Shingles. What about preventing Shingles? There is a relatively recent new weapon in the war on Shingles. "The shingles vaccine, Zostavax by Merck, was licensed in May 2006 after a study of more than 38,500 men and women 60 and older showed that it prevented about half of cases of shingles and reduced the risk of Post Herpetic Neuralgia by two-thirds". It still can't guarantee you won't get Shingles but if you do it will probably be a milder case of Shingles.







  • NINDS Shingles Information Page



    "Until the unknowns are resolved, the vaccine is not recommended for those with immune systems weakened by disease or drug treatment, women who are pregnant or might be pregnant and people with active untreated tuberculosis. Nor should the vaccine be given to anyone who has had a life-threatening allergic reaction to gelatin or the antibiotic neomycin".

    CAN YOUR THINKING LESSEN CHANCE OF ALZHEIMERS? ALTER CHEMICALS AND BRAIN PATHWAYS: STUDY SAYS YES

    CAN YOUR THINKING LESSEN CHANCE OF ALZHEIMERS? ALTER CHEMICALS AND BRAIN PATHWAYS: A MORE AWARE ACTIVE CONSCIENTIOUS PERSONALITY SOMEHOW ALTERS THE BRAIN AND LESSEN ALZHEIMER RISK: A STUDY SUGGESTS HOW YOU THINK MAY IMPACT CHANCE OF ALZHEIMER



    During the 1990s, the ranks of (people over 100) nearly doubled, from about 37,000 counted at the start of the decade, to more than an estimated 70,000 (in 2000). And analysts at the Census suggest that this per-decade doubling trend may continue, with the centenarian population possibly reaching 834,000 by the middle of the next century (2050).Census Report Shows Exponential Growth in Number of Centenarians





    A remarkable finding suggests that how you think may have an impact on whether you develop Alzheimers. How does what you think affect your brain? Could your thought affect chemical and neurological pathways in your brain? In a proportional hazards regression model adjusted for age, sex, and education, a high conscientiousness score (90th percentile) was associated with an 89% reduction in risk of Alzheimer disease compared with a low score (10th percentile) "A purposeful personality may somehow protect the brain, perhaps by increasing neural connections that can act as a reserve against mental decline, said study co-author Robert Wilson of Chicago's Rush University Medical Center".

    "This adds to our knowledge that lifestyle, personality, how we think, feel and behave are very importantly tied up with risk for this terrible illness," Wilson said. "It may suggest new ideas for trying to delay the onset of this illness."


    The study
  • Conscientiousness and the Incidence of Alzheimer Disease and Mild Cognitive Impairment is in Archives of General Psychiatry.




    "Renee Goodwin of Columbia University's Mailman School of Public Health was not involved in the new study but has done similar work that found a connection between conscientiousness and better health."It's having self-discipline and energy, doing the healthy things," Goodwin said".

    "The conscientiousness scores were based on how people rated themselves, on a scale of 0 to 4, on how much they agreed with statements such as: "I work hard to accomplish my goals," "I strive for excellence in everything I do," "I keep my belongings clean and neat" and "I'm pretty good about pacing myself so as to get things done on time."
