Does Testosterone Lower Risk of Heart Attacks and Stroke? | Medical Research News and I... - 0 views

  •  
    This is a short interview of the author on a recent retrospective review that revealed no increase in cardiovascular events in men.  The author rightly points out his data, which is quite different than the previous JAMA and PLOSone publications which showed an increase in cardiovascular events.   However, the lead author points out the main problem with comparisons:  his study group was younger and healthier.  So, the comparison is apples to oranges.  Studies still point to increased risk of Testosterone therapy in men with pre-existing CVD.  This new study does not refute this point at all.   Another serious flaw here, is that only Testosterone was followed.  This logic is seriously flawed as I have previously documented.  The author points out the flaw in the levels in the JAMA study post treatment.  But he fails to account for the the lack of adequate pathway assessment i.e.aromatazation.  Also, no inflammatory cytokine evaluation was performed in that study.  Both of these should have been highlighted.    In contrast, a positive was the length of follow.

Thyroid Replacement Therapy and Heart Failure - 0 views

  • A good biomarker of intracardiac TH signaling would be helpful but has not been identified. In the absence of such a marker, a rational, cautious therapeutic approach might be to restore and maintain over time biochemical euthyroidism as documented by normal circulating levels of TSH, FT4, and FT3.
  • a low-T3 state resulting from altered peripheral TH metabolism secondary to caloric restriction is associated with impaired cardiac contractility
  • Low-T3 syndrome is the central finding and defines the illness in a variety of acute and chronic severe nonthyroidal illnesses with cardiac origin, including MI, HF, and surgically treated cardiac disease.1 Low circulating levels of T3 in the absence of primary thyroid hypofunction have been found in 20% to 30% of patients with dilated cardiomyopathy.

  • FT3 levels were inversely correlated to coronary artery disease
  •  
    Great review of the current understanding of thyroid hormone metabolism in cardiac tissue.  Low T3 and increased rT3 (via increased D3 activity) is CLEARLY associated with poor cardiac performance and post MI and CHF is associated with poor outcomes.  T3 is critical in cardiac remodeling and recovery post MI.  T3 is actually a vasodilatory in the coronary arteries.   Why a endocrinologist would call rT3 useless only points to their ignorance of the literature.

    study finds restoration of HPA in men with low T.  This was performed via clomid therapy at 25 to 50 mg daily for 4 months.  Increase in pulsatile LH, increase in serum Testosterone levels, and increase in sexual function was found.  Clomid restores HPA function that is suppressed from estrogen inhibition.  In this case, clomid is function as an estrogen antagonist.

Intravenous Fluid Use in Athletes - 0 views

  • Treatment of exercise-associated hyponatremia with hypertonic IV infusion to correct plasma sodium levels is also a standard and accepted use of IV fluid infusions
  • athletes who present for medical care with hypernatremia who cannot tolerate oral fluids can benefit from IV fluids
  • Vaporization of sweat accounts for 80% of heat loss in hot, dry atmospheric conditions. This mechanism of water loss is the major contributor for exercise-associated dehydration
  • ...30 more annotations...
  • The rate of water loss can be quantified through measurement of sweat rate
  • Pre- and postexercise body weight measurements are the most common means to estimate overall water loss but are condition specific
  • It appears that 1% to 2% body weight loss is well tolerated by the exercising athlete
  • Dehydration, defined as greater than 2% loss of body weight, can negatively affect performance
  • In highly trained endurance athletes, plasma volume and sodium serum concentration were preserved despite a 5% body weight loss
  • In Ironman triathletes, dehydration to 5% body weight loss did not correlate with occurrence of medical complications
  • hydration should begin hours prior to exercise, especially if known deficits are present, and fluids should be consumed at a slow, steady rate, with 5 to 7 mL/kg taken 4 hours prior to exercise
  • Sodium concentration did not produce significant changes in the rate of absorption but was primarily dependent on carbohydrate concentration
  • Replacing 150% of body weight loss over 60 minutes has been tolerated without complications
  • IV treatment of severe dehydration (>7% body weight loss), exertional heat illness, nausea, emesis, or diarrhea, and in those who cannot ingest oral fluids for other reasons, is clinically indicated
  • A recent survey of the National Football League teams revealed that 75% (24 of 32) of the teams utilized IV infusion of fluids for prehydration in at least some otherwise healthy individuals
  • In the National Football League, an average of 1.5 L of normal saline was administered approximately 2.5 hours prior to competition
  • after 2 hours of exercise, the rectal temperature was 0.6° higher in the group not receiving IV infusion. Also, stroke volume and cardiac output were 11% to 16% lower in the control group versus the IV infusion group.
  • Recent evidence suggests the etiology of EAMC is related to muscle fatigue and neuronal excitability
  • no correlation between hydration status or electrolyte concentrations with EAMC
  • there may be a subset of muscle cramping that is associated with a loss of both body fluid and sodium
  • Glycerol is the primary agent for oral hyperhydration
  • elevation of plasma volume by 200 to 300 mL via dextran infusion resulted in 15% increase in stroke volume, 4% increase in VO2 max, and an increase in the exercise time to fatigue
  • Neither the tonicity nor mode of hydration resulted in improved speed of rehydration, greater fluid retention, or improved performance
  • There are beneficial anecdotal reports of EAMC treatment in elite and professional-level athletes with IV hydration during the course of an event
  • Plasma volume was better restored during rehydration with IV fluids at preexercise and 5 minutes of exercise. At 15 minutes, there was no difference between IV and oral rehydration
  • More rapid restoration of plasma volume was accomplished in the IV treatment group with no advantages over oral rehydration in physiological strain, heat tolerance, ratings of perceived effort, or thermal sensations
  • No difference was found in exercise time to exhaustion. IV and oral rehydration methods were equally effective. Heart rates were statistically higher in the oral rehydration group through 75 minutes of exercise, and there were higher increases in norepinephrine plasma concentrations
  • No significant differences between the groups were found for time to recovery, number of days with pain, number of days with stiffness, sleep disturbance, fatigue, rectal temperature, and loss of appetite
  • The current data suggest that IV rehydration is faster than oral
  • There may be physiological benefits of decreased heart rate and norepinephrine in athletes rehydrated via IV route
  • Postexercise blood 1 hour and 24 hours showed no differences in circulating myoglobin or creatine kinase
  • The use of IV fluid may be beneficial for a subset of fluid sensitive athletes
  • this should be reserved for high-level athletes with strong histories of symptoms in well-monitored settings.
  • Volume expanders may also be beneficial for some athletes

Testosterone and metabolic syndrome: a meta-analysis study. - PubMed - NCBI - 0 views

  •  
    Men with metabolic syndrome have lower Testosterone levels when compared to "healthy" individuals.  All men with MetS should have a full androgen analysis performed.  This meta-analysis of 20 studies found Testosterone therapy reduced fasting glucose, HOMA, triglycerides, waist circumference by Testosterone in men with MetS.  This study found that Testosterone therapy increased HDL as well.

A Friendly Tricycle For Disabled People - 0 views

  •  
    A tricycle for special needs is made so can go along for the ride in wheelchair or sitting in a special seat, both of which are attached right in front of another adult's trike. Tricycles to accommodate a vast array of special needs. Hand-pedaled recumbent tricycles are available for those without the use of their legs. Children, teens and adults with cerebral palsy and similar disorders can select tricycles specially designed to increase strength and coordination. Caregivers to autistic children can ride with their child on tandem special needs tricycles built to accommodate one adult and one child rider. Accessories are also available to convert standard trikes to suit specific needs. The objective of tricycle design is to produce wheelchairs that perform well and can provide appropriate seating and postural support without compromising strength, durability and safety. A Hand Driven Tricycle, abbreviated to trike is a three-wheeled passenger vehicle, usually carrying a single rider. The tricycle consists of a motorbike and an attached passenger sidecar and should not be confused with the tricycle. The trike is a motorized three-wheeled pedicab. Human-powered trikes are powered by pedals or hand cranks. Motorized trikes use motorcycle or scooter,or electric motors. Tricycles tend to be used for commercial purposes: such as "pedicabs" for transport passengers, and freight trikes for making deliveries. In the adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children and senior adults alike for their apparent stability versus a bicycle; but a conventional trike has poor dynamic lateral stability, and the rider must take care when cornering to avoid tipping the trike over.
