SPORTS MEDICINE: Vitamin D more vital than ever | John Doherty

The best opportunity for preventive care, according to Wojtys, occurs in the teenage years, decades before diagnosis. “Peak bone mass is dependent on 5 main factors: sex, race, hormones, nutrition and physical activity,” he wrote. “Sex and race are nonmodifiable, while nutrition, physical activity and hormones are.

“While all the first 20 years of life are important in bone development, approximately 40% to 60% of adult bone mass is achieved during adolescence. Interestingly, 25% of peak bone mass is acquired during the two-year span around peak height velocity: 12.5 years of age for girls and 14 years of age for boys. Nearly all (90%) peak bone mass will have accrued by the age of 18 years, often determining our fracture risk for the rest of our lives.”

Dietary calcium is key for developing strong bones.

Wojtys advises teenagers get 1,300 mg per day for optimal growth. “Keeping in mind that

SPORTS MEDICINE: National Sudden Cardiac Arrest Month a time to look back | John Doherty

When the season did resume for the Blues, though, in a bubble in Edmonton in July, the team announced that Bouwmeester was not going to be with them.

It is unlikely he will ever be with the Blues — or any other NHL team — again. Yet, the former Olympic gold medalist (Sochi 2014) should still be thankful. The presence of medical professionals and their swift use of the AED made his chance of survival much greater.

A study published in 2018 in Sports Health identified 132 cases of SCA suffered among athletes age 11 to 27 between 2014 and 2016. Survival to discharge from a hospital was the result for 64, or 48% of the victims. However, if an AED was present and used promptly, the survival rate increased to 89%. Furthermore, whether an AED was available or not, if an athletic trainer was in attendance, the survival rate

Notre Dame president Rev. John Jenkins tests positive for coronavirus after White House SCOTUS ceremony

Jenkins was the latest prominent leader to announce an infection Friday, a day that began with the revelation that Trump and the first lady had tested positive.

During his self-quarantine this week, Jenkins learned that a colleague with whom he had been in regular contact tested positive for the virus, according to an announcement sent to campus Friday afternoon. Jenkins was tested and found to be positive as well, so he is beginning “an extended period of isolation as indicated by University medical personnel and county health officials,” the announcement said.

In the statement to campus, Jenkins said, “My symptoms are mild and I will continue work from home. The positive test is a good reminder for me and perhaps for all of how vigilant we need to be.”

A spokeswoman for the university said they would have no further comment.

Last month, the prestigious Catholic university in Indiana switched

Brisbane doctor John Robert Ullman, 52, accused of supplying drugs to bikies

A Brisbane doctor accused of supplying and trafficking drugs to outlaw motorcycle gang members has been suspended from practising medicine by the Health Ombudsman.

Chermside skin cancer doctor John Robert Ullman, 52, was arrested and slapped with more than 160 charges last week relating to allegations he supplied testosterone, diazepam and other drugs to at least 39 different people over a two-year period.

As part of his bail application, Ullman’s lawyer Tyronne Thomas argued the doctor should be released because he was the only GP rostered on to work during the school holidays at the skin cancer clinic.

“He also within the next couple of weeks he also has patients that require skin cancer treatment,” Mr Thomas told the court on Wednesday last week.

“I’m instructed he’s the only general practitioner working at the clinic over the school holidays.”

SPORTS MEDICINE: Current chaos in keeping with 2020 | John Doherty

It is bad enough that the stands are empty. At this rate, the NFL’s rosters will soon be empty of stars.

While soft tissue injuries seem to be out of control among the pros, at least the NFL has a handle on COVID-19. Just ask the five head coaches fined $100,000 by the league for not wearing masks during their games. Pete Carroll (Seahawks), Vic Fangio (Broncos), Jon Gruden (Raiders), Sean Payton (Saints), and Kyle Shanahan (49ers) all have lighter wallets.

Meanwhile, Notre Dame has a lighter schedule — at least for now, thanks to the postponement of Saturday’s game with Wake Forest, the result of 23 players being unavailable, infected with COVID-19 or quarantined thanks to contact tracing.

The Irish are not alone at the college level. As the Big Ten and Mid-American Conference attempt to start an abbreviated season (with no bye weeks built in to accommodate COVID-related
