A study to determine the progression of individuals throughout time

Distribution of instantaneous glucose slopes of the 55 individuals by years from diabetes onset slopes estimated by GEM. Shown are the 25th, 50th medianand 75th percentiles and range of the glucose rates of change for the individuals in the study. Approximately 6 years before diabetes onset there were no longer any individuals with an overall negative slope, the exponential effect outweighing any initial downward trend.

A study to determine the progression of individuals throughout time

Medicine January 11, By Brenda L. Mooney BOSTON — For the first time, researchers have categorized chronic traumatic encephalopathy CTEthe degenerative brain disease associated with repeated brain trauma in military combat and contact sports, into four stages of severity.

Of the 68 cases of CTE found in males between 17 and 98 years old, 64 were athletes, and 18 of those were also military veterans.

Of the athletes, 34 were professional football players, nine only played college football and six had only played high school football.

The group included three additional veterans who did not have a sports background. Evaluation of one of the study subjects — for whom self-injurious head-banging behavior was the sole environmental exposure — underscored the view that repetitive brain trauma alone is sufficient to trigger CTE in some cases.

CTE, which appears to be slowly progressive in most individuals, is characterized in early stages by the presence of abnormal deposits of a protein called tau in the form of neurofibrillary tangles, glial tangles and neuropil threads throughout the brain.

These tau lesions eventually lead to brain-cell death. Currently, CTE can only be diagnosed postmortem. Researchers also found evidence of the condition in 50 football players, including 33 who played in the National Football League NFLone in the Canadian Football League CFLone semi-professional player, nine college players and six high school football players.

CTE also was identified in four National Hockey League NHL players, one amateur hockey player, seven professional boxers, one amateur boxer, and one professional wrestler.

Based on interviews with families of the deceased donors, researchers were able to develop a list of symptoms common to stages of the disease: While CTE appeared to be slowly progressive in most of the study subjects, it may not progress or progress at the same rate in all patients, study authors noted.

In addition, one-third of the CTE cases were diagnosed with additional neurodegenerative disease, including: Years before the onset of cognitive and behavioral symptoms, most of the individuals with CTE and motor neuron disease CTE-MND had suffered symptoms of motor weakness, atrophy and fasciculations, or muscle twitches, the study notes.

The next goal of researchers is developing methods to diagnose CTE during life, according to co-author Robert Stern, PhD, Boston University professor of neurology and neurosurgery. A study released this summer also found CTE indications in brain tissue from blast-exposed military personnel.

In a worst-case scenario,veterans could be at risk for CTE. The Boston University Center for the Study of Traumatic Encephalopathy said it has permission to release the following names of those who were diagnosed with CTE in this study.

In addition, the BU CSTE obtained permission to release the brain images from an anonymous Marine veteran of the wars in Iraq and Afghanistan, who suffered multiple concussions in combat and in sports. They also have the opportunity to provide a saliva sample for genetic testing.An ultrasound exam is a procedure that uses high-frequency sound waves to scan a woman’s abdomen and pelvic cavity, creating a picture (sonogram) of the baby and placenta.

What is Raynaud’s phenomenon? Raynaud’s phenomenon is a condition that affects your blood vessels. If you have Raynaud’s phenomenon, you have periods of time called “attacks” when your body does not send enough blood to the hands and feet.

This study was the first to evaluate 6-min walk distances and speeds in individuals with RYR1-RM in order to assess disease progression and fatigability over a course of 6 months.

Our findings confirm clinical reports of RYR1 -RM as being a group of stable or slowly progressive diseases.
