Here is the news:

Prophylactic Antibiotic Improves Instrumented Vaginal Deliveries 

Women who give birth via a vaginal delivery that requires an instrumental assist using either forceps or a gentle vacuum benefit from a single dose of a common antibiotic.  A just published study from the University of Oxford in The Lancet journal shows a significant reduction in post-partum infection after one intravenous dose of amoxicillin-clavulanic acid, better known as Augmentin.

 

The randomized, blinded study looked at nearly 3500 women who gave birth in 27 British obstetric units.  The group that received a single dose of antibiotic enjoyed a 42% reduction in postpartum infection.  The antibiotic advantage was somewhat greater for those women requiring forceps versus vacuum assist.  There also appeared to be an antibiotic advantage for those women requiring an episiotomy despite the lack of need for instrumentation. 

 

Prophylactic antibiotics are currently recommended by the World Health Organization for all women delivering by c-section.  This study suggests the same recommendation should be extended to women who require either a forceps or vacuum assist for their vaginal delivery. 

 

Meanwhile, if you or a woman you love is having a vaginal delivery with instrumentation or requiring an episiotomy, ask the managing physicians to consider a dose of Augmentin as soon as possible after delivery.

How Much Coffee Is Too Much

More than 6 cups of coffee a day drives blood pressure to dangerous levels and bumps up the risk of heart disease by 22%.   A new study from the University of South Australia derives this conclusion from a review of data from 347,000 Aussies between the ages of 37 and 73 years.

 

Coffee has many beneficial effects including waking us up, boosting our energy, and focusing our thinking, but, as is the case with many things in our lives, more is less.  An estimated 3 billion cups of coffee are consumed daily worldwide.  Do make sure that your consumption reflects the principle of moderation and amounts to fewer than 6 cups a day.

Sunscreens Won’t Lower Your Vitamin D But May Be Toxic

With the rates of skin cancer including the deadly melanoma escalating, sunscreen is a must for beach goers and particularly vital for those with light complexions.  Since sunlight is a driver for Vitamin D synthesis in our bodies, some worry that sunscreen use will create a Vitamin D shortfall.

 

A study just published in the British Journal of Dermatology shows that sunscreen use does not prevent Vitamin D synthesis despite protecting against sunburn and cancerous skin cell mutations.   Those sunscreen formulations with a high UVA protection factor allowed more Vitamin D production.

 

Sunscreen overuse can be harmful, however, as application and reapplication can drive absorption of sun-blocking chemicals into the body.  A study from the FDA shows that 4 daily applications of sunscreen by spray, lotion, or cream drives absorption of the most common sunscreen chemicals, oxybenzone, octocrylene, and ecamsule to levels deemed possibly toxic.

 

The bottom line is that you should use sunscreen but avoid exposure to the chemicals.  One way to do this is to use unblocking mineral creams such as zinc oxide or tandem dioxide.  If you do use chemical sunscreens, minimize reapplications by limiting your time in the sun.

Meditation Could Backfire

Meditation is designed to relax you, but a new study from University College London finds that one in every four persons who regularly meditates experiences a decidedly unpleasant experience on a regular basis. The investigators surveyed more than 1200 persons who had regularly meditated for at least 2 months.

 

The unpleasant experiences included anxiety, fear, distorted emotions or thoughts, and an altered sense of self or the world.  Those most likely to have negative meditation experiences were those subjects who had been at a meditation retreat, those practicing deconstructive meditation, and those without deep religious beliefs.  Bad meditation trips were slightly more likely for men than women.

 

Meditation can have very positive effects.  Just be aware, though, that it may trigger negative sensations so buyer beware!

Losing Your Appendix May Bump Up Your Parkinson’s Risk

A study of 62 million persons in 26 US health systems shows that those who had an appendectomy for any reason were three times more likely to develop Parkinson’s Disease.  These results are being presented at the Digestive Disease Week 2019 meeting this month.

 

This study represents yet another link between the gastrointestinal tract and the brain.  This is only an association, and further investigations must reveal the how and why appendectomy could affect the development of Parkinson’s Disease. 

 

This data is ammunition for those who recommend a conservative approach to appendicitis using antibiotics and dietary modification.  It is also food for thought before undergoing a prophylactic appendectomy if you are having other abdominal surgery. 

 

 Until we know more, if you can, hold on to your appendix.

Recreational Sports Improve Grades

Ok college students!  Looking to bump up your GPA?  Get yourself signed up for intramural sports ASAP!

 

A study of some 1800 Michigan State University freshmen revealed that those playing intramural sports earned a GPA average of 3.25 compared with the 3.07 GPA earned by the couch potatoes.  In addition, the data revealed that the athletes were less likely to drop of fail a course and were 40% more likely to advance and become sophomores during their second year at MSU.  The students in each group were matched by high school GPA, gender, race, socioeconomic status, and legacy status.

 

Lest you think that more extracurriculars were better, the study reported that between 4 to 6 was the ideal number.

Avocado Kills Hunger

If you’re looking to suppress your hunger without “pigging out” and bumping up your daily calorie count, try substituting avocados for carbs in your diet.  Nutrition scientists at the Illinois Institute of Technology studied some 31 overweight and obese subjects and modified their diets.

 

They replaced carbohydrate calories with fat calories from avocados on a calorie-for-calorie basis.  They used either whole avocados or half avocados to create dose-response data.

 

The final results demonstrated that avocados can suppress hunger and increase the hormones typically released when a person feels full.  The fats and fiber contained in avocados are healthy additions to anyone's diet, and this soft fruit is a useful weapon in the battle against obesity and diabetes.

Skin-sparing Mastectomy A Safe Alternative

A new Mayo Clinic study shows that many breast cancers may be safely and completely removed without sacrificing the overlying skin and nipple.  This study is being presented to the American Society of Breast Surgeons annual meeting this month.

 

The study looked at skin and nipple-sparing mastectomies in 769 women undergoing a total of 1300 surgeries.  At one year following surgery, the technique was considered a success in 97% of cases both in terms of cancer eradication and breast reconstruction.

 

Longer-term followup data will be necessary to determine whether or not skin- and nipple- sparing will become the norm.  Even at this point, though, this information from Mayo suggests that such conservative surgery should be considered an option for many women.

Cialis Helps Heart Failure

Tadalafil, marketed as Cialis, is one of the popular drugs used for erectile disfunction (ED).  Now a study at Britain’s University of Manchester shows that cialis slows or reverses the progression of congestive heart failure.

 

The study, just published in the journal Scientific Reports, was carried out in sheep since their hearts are physiologically similar to the human heart.  Heart failure was induced in the sheep using pacemakers to overdrive and exhaust their hearts.

 

When the sheep were given Cialis at a dose equivalent to that taken by humans for ED, their heart function improved and their hearts were again capable of responding to adrenaline, a key signaling agent in both sheep and humans.  Cialis and drugs like it including Viagra work in part by dilating blood vessels, and this effect may reduce the resistance against which the heart must pump, the so-called after load, permitting it to function better.

 

More studies are needed to explain the exact mechanism of action, but if you or a family member experiences drug-resistant congestive heart failure, a trial of cialis may be useful.  The drug is generally well-tolerated with few side effects.

Nuts to High Blood Pressure

Eating walnuts instead of other sources of fat in a diet can lower your blood pressure.  This conclusion comes from a study of 45 overweight or obese subjects by nutritionists at Penn State just published in the Journal of the American Heart Association.

 

The investigation found that eating walnuts to replace at least 5 percent of the typical 12 percent saturated fat that most Americans consume significantly lowered the body’s central diastolic or resting blood pressure. A normal diastolic pressure level is key for preventing heart disease and stroke.  The walnuts did not lower either systolic blood pressure or arterial stiffness.

 

The next time you’re looking for a heart healthy snack, skip the potato chips and reach instead for the can of walnuts.  For an even greater effect, replace those french fries you know you always order with walnuts and green beans.  Your heart and circulation will be glad you did.

An Early Diagnosis of Autism Is Possible

Neuroscientists at the University of California-San Diego’s Autism Center of Excellence now report that autism may be reliably diagnosed in babies as young as 14 months thereby permitting effective, early intervention.  The researchers studied more than 1200 toddlers who were first evaluated between their first and third birthdays and were then followed with at least one additional thorough assessment later in childhood.

 

The ability to reliably diagnose autism or autism spectrum diagnosis occurs by 14 months of age.  Diagnostic reliability is only 50% at 12 months, rises to 79% by 14 months, and is 83% by 16 months.  Only 2% of those first diagnosed with autism during infancy later had that diagnosis dropped.

 

The mean age at diagnosis for autism is currently between 3 and 4 years.  Research studies suggest that autism in its many shades develops in utero during the first or second trimesters, and this new information confirms that a reliable, earlier diagnosis is definitely possible.  

 

Many children are diagnosed early because of parental observation. The Autism Awareness Center lists 7 signs that your baby may have autistic tendencies:

  • No social smiling.

  • Lack of eye contact.

  • No response to name.

  • No social anticipation to being picked up or playing Peek-a-boo.

  • Poor visual tracking.

  • Lack of social babbling.

  • Fixation on unusual objects such as parts of toys and floor/ceiling patterns.

 

If you notice these signs, speak with your pediatrician about a formal diagnostic evaluation.

Morning Workouts Drive Better Thinking

Starting the day with a moderate-intensity walking exercise session does help your mind function better.  The latest Australian study, just published in the British Journal of Sports Medicine, looked at more than 65 subjects of all genders and 55 to 80 years of age.

 

The morning workout was associated with improved attention, concentration, executive function, visual learning, and working memory.  The study also revealed that periodic 3 minute walking breaks during the day further improved test results when compared with those clocked by those who had no additional exercise after the morning session.

 

This study is additional proof that the extra exercise-driven blood flow to your brain and the exercise-induced chemical agents such as endorphins that flow in that blood fine-tune your brain to perform optimally.  Although the study was completed in middle-aged and older persons, the exercise would likely also benefit anyone of any age.

E-Cigarettes Are Contaminated With Bacteria and Fungi

Need more reasons not to use e-cigarettes and to convince your children to avoid them?  Besides the fact that they spew addicting nicotine and toxic flavoring chemicals?   A study from the Harvard School of Public Health now finds bacterial endotoxins and fungal cell wall remnants in 75 popular e-cigarette products from 10 top-selling US brands.

 

The investigators studied 37 e-cigarette cartridges and 38 e-liquid products that are used to refill cartridges.  They demonstrated that 23% of the products contained significant concentrations of gram-negative bacterial endotoxins and a whopping 81% of the products were contaminated with fungal by-products.  

 

Other studies have confirmed that these bacterial endotoxins and fungal glucans trigger acute and chronic respiratory problems.  Asthmatics or those with pre-existing lung disease would be particularly vulnerable.

 

This study joins so many others that underscore what is just common sense: don’t inhale poisons unless you have a death wish.  If the latter is the case, please get some help.

A Simple Test Predicts Lasting Concussion Effects

Pediatric sports medicine specialists at the University of Colorado report that a simple test, the Romberg test, can predict which children will suffer lasting effects from a concussion and would benefit from proactive therapy.  Their study was just published in the Journal of Neurosurgery;Pediatrics.

 

The data from more than 350 children and adolescents with a mean age of nearly 15 years showed that an abnormal Romberg balance test was the best predictor of prolonged symptoms after the traumatic brain injury.  This test was more predictive than other variables including self-reported headache severity, headache frequency, confusion, forgetfulness,  inattention, memory lapses, fatigue, and dizziness failed to correlate with the duration of issues post-concussion.

 

The Romberg test is simple to perform.  The subject stands with feet together and eyes closed.  The test is deemed positive if the individual cannot maintain balance with minimal movement.

 

This finding is important because a positive Romberg test will triage children who have sustained concussions into timely physical and psychological therapy.

Late Pregnancy Ultrasound Benefits Mother, Baby, and the Bottomline

A planned ultrasound at 36 weeks will detect undiagnosed breech presentations in time to allow intervention and prevention of dangerous fetal distress and emergency c-sections.  This recommendation springs from a study by public health specialists at Britain’s University of Cambridge.

 

The investigators screened nearly 3900 women during their first pregnancies with a 36 week ultrasound.  The screening detected a 4.6% incidence of breech presentation more than half of which were unsuspected.  The women were given the choice of attempting to turn the baby, so-called external cephalic version, or a an elective c-section. Those whose babies would not reposition underwent the elective c-section.

 

In the UK, the 36 week ultrasound that costs about 13 pounds or US$17, would prevent about 15,000 undetected breech presentations, more than 4,000 emergency c-sections and 8 baby deaths a year.  The effects are even more dramatic when extrapolated to the US population.

 

If you are pregnant, would might want to ask your obstetrician about a 36 week ultrasound.  It would save much heartache later on.

Children’s Author Roald Dahl Writes About Measles

The author of “Charlie and the Chocolate Factory” and “Matilda,” Roald Dahl, wrote in 1988 about his experience when his daughter developed measles. 

 

"Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything.

 

'Are you feeling all right?' I asked her.

'I feel all sleepy,' she said.

 

In an hour, she was unconscious. In twelve hours she was dead.”

 

Dahl went on: “The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was...in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. 

 

On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunized against measles.

 

...I dedicated two of my books to Olivia, the first was ‘James and the Giant Peach’. That was when she was still alive. The second was ‘The BFG’, dedicated to her memory after she had died from measles. You will see her name at the beginning of each of these books. And I know how happy she would be if only she could know that her death had helped to save a good deal of illness and death among other children." 

 

Now listen to this…. He adds ironically in 1988: “It is not yet generally accepted that measles can be a dangerous illness. Believe me, it is. In my opinion parents who now refuse to have their children immunized are putting the lives of those children at risk.

 

In America, where measles immunization is compulsory, measles like smallpox, has been virtually wiped out.  Here in Britain, because so many parents refuse, either out of obstinacy or ignorance or fear, to allow their children to be immunized, we still have a hundred thousand cases of measles every year. Out of those, more than 10,000 will suffer side effects of one kind or another. Many will develop ear or chest infections. About 20 will die.”

 

Roald Dahl would do anything to bring back his child.  All that you have to do to prevent the same tragedy from befalling your children is to see that they get the MMR vaccine.
