  • In longitudinal studies, decreased levels of total testosterone and SHBG predicted an increased incidence of metabolic syndrome in nonobese men
  • Free testosterone level is not associated with the prevalence of metabolic syndrome in middle-aged and older men
  • Levels of free, bioavailable and total testosterone are lower in men with T2DM than in age-matched controls,34, 35 and decreased total testosterone level predicts incident T2DM in middle-aged men.
  • men with T2DM commonly have low total or free testosterone levels
  • Total, bioavailable and free testosterone levels are inversely correlated with fasting insulin level and insulin resistance in middle-aged men without T2DM
  • total testosterone is positively correlated with insulin sensitivity in men with normal or impaired glucose tolerance or T2DM
  • low SHBG level is more strongly associated with metabolic syndrome than low total testosterone in aging men
  • the recognized association between low SHBG level and insulin resistance
  • Low levels of SHBG are also associated with smaller, denser LDL-cholesterol molecules in nondiabetic men,58 and were found to predict increased cardiovascular disease mortality in one study of older men
  • Low levels of SHBG might reflect obesity, insulin resistance and overall poor health
  • Compared with those who have normal testosterone levels, men aged 40 years or more with total testosterone levels <9.8 nmol/l or elevated LH level have greater CIMT
  • In men aged 73–94 years, total testosterone was inversely correlated with CIMT
  • a prospective analysis of men aged 73–91 years, progression of CIMT was not related to total testosterone level, but it was inversely related to free testosterone level
  • A study of men aged 55 years or more found that those with total and bioavailable testosterone levels in the highest tertile had a lower risk of severe aortic atherosclerosis (detected by radiography as abdominal aortic calcification) than those with the lowest testosterone levels.
  • a large study of men aged 69–80 years, those with total or free testosterone in the lowest quartile had increased odds of lower-extremity peripheral arterial disease
  • the possibility of reverse causation has to be considered, as systemic illness can result in decreased testosterone levels
  • previous case–control studies and longitudinal studies have failed to identify low testosterone levels as strong predictors of clinically significant coronary disease
  • Reviews of trials on testosterone therapy in men with either low or low-to-normal testosterone levels have not shown consistent beneficial effects either on lipid profiles or on actual cardiovascular events.24, 54, 55 These trials, however, have not been designed or powered to detect treatment-related differences in cardiovascular outcome

    Observational study finds BMI increase of 0.375 in both men and women per year.  The waist circumference also increased by 0.37% per year in women compared to 0.27% in men.  There was a significant reduction in physical activity over the same time period.  In women, the reporting of physical inactivity increased to 52% FROM 19% compared to 44% FROM 11% in men.  The authors found no association with change in calories.  However, an assessment in quality of calories would have likely shown a glaring difference.  Clear causation can not be concluded due to the fact that the study was observational.

    young children have a different set of needs than adults. Aesthetically, devices designed for kids are often sleek and colorful, and functionally, they are typically lightweight and adjustable. As any parent knows, young people don't stay the same size for long and since a wheelchair is a major purchase -- don't want a simple growth spurt to render it useless. Wheelchair category offers models that feature seat width and depth adjustability, elevating legrests, and other versatile features. As a weight-bearing activity is critical to proper physical and mental function-which is why children with cerebral palsy, who may sit for stretches in a wheelchair and typically are unable to stand on their own, can benefit greatly from pediatric standers as part of a comprehensive pediatric rehabilitation program. Pediatric standers are offered in passive, active and mobile formats: Passive standers stay in one place and feature a support surface, active standers allow reciprocal movement of the extremities while in a standing position, and mobile standers enable users to self-propel.

    Cerebral palsy (CP) is a group of conditions caused by medical abnormalities in the development of a fetus or the early life of a child. These lead to damage or delayed development in the brain. The disorder is permanent and, though it does not worsen with age, the level of functionality of a person with cerebral palsy varies widely: in some cases, effects may be very minor, while in others, movement is impaired to the extent that a wheelchair is required. Common complications associated with CP vary by the type of CP disorder but can include vision problems, seizures, learning disabilities, and issues speaking, writing, and performing other tasks. Cerebral palsy causes problems with muscle tone, movement, balance and/or coordination. Symptoms and effects range from mild to severe. In some infants, problems are evident soon after birth. In others, diagnosis comes in later infancy or toddlerhood. Cerebral Palsy Wheelchair Description: The model designed for cerebral palsy child only. Ultra light weight aluminium alloy frame.

  • Studies have shown that ED may be an early biomarker of general endothelial dysfunction, atherosclerosis and CVD
  • testosterone treatment of hypogonadal young and older men improves sexual function, increases lean mass and decreases fat mass
  • In men with low serum testosterone (for example, <8 or 230 nmol l−1) with obesity, metabolic syndrome and diabetes mellitus, treatment with testosterone is warranted
  • ...12 more annotations...
  • In obese middle-aged men, testosterone treatment reduced visceral adipocity, insulin resistance, serum cholesterol and glucose levels
  • testosterone replacement has a favorable impact on body mass, insulin secretion and sensitivity, lipid profile and blood pressure in hypogonadal men with the metabolic syndrome as well as type 2 diabetes mellitus
  • Testosterone significantly inhibits lipoprotein lipase activity, which reduces triglycerides uptake into adipocytes in the abdominal adipose tissue
  • testosterone treatment decreased endogenous inflammatory cytokines (tumor necrosis factor-α and IL-1β) and lipids (total cholesterol) and increased IL-10 in hypogonadal men
  • Testosterone treatment reduced leptin and adiponectin levels in hypogonadal type 2 diabetic men after 3 months of testosterone replacement
  • available data clearly show a relationship between obesity, low testosterone levels and ED
  • Obesity adversely affects endothelial function and lowers serum testosterone levels through the development of insulin resistance and metabolic syndrome
  • Metabolic disturbances as well as production of cytokines and adipokines by inflamed fat cells may be causal factors in the development of ED
  • The onset of ED and the associated risk of CVD may be delayed through lifestyle modifications that affect obesity, such as diet and exercise
  • Very low testosterone levels contribute to the development of ED in obesity, metabolic syndrome and type 2 diabetes mellitus
  • Obesity is associated with low total testosterone levels that can be explained at least partially by lower sex hormone-binding globulin (SHBG) in obese men
  • epidemiological studies have shown a negative correlation between BMI and total testosterone and to a lesser extent with free and bioavailable (biologically active) testosterone levels

  • the threshold serum testosterone level below which adverse clinical outcomes occur in the general population is not known

  • Researchers tried to examine whether serum total or free testosterone would be a better/more reliable choice when studying the effect of testosterone. The results were mixed. Some reported significant associations of both serum total and free testosterone level with clinical parameters25, whereas others reported that only serum free testosterone26 or only serum total testosterone6 showed significant associations.

      this equates to a 4 ng/dl decline annually in total Testosterone.
  • In experimental studies, androgen receptor knockout mice developed significant insulin resistance rapidly
  • In mouse models, testosterone promoted differentiation of pluripotent stem cells to the myogenic lineage
  • testosterone decreased insulin resistance by enhancing catecholamine induced lipolysis in vitro, and reducing lipoprotein lipase activity and triglyceride uptake in human abdominal tissue in vivo
  • by promoting lipolysis and myogenesis, testosterone might lead to improved insulin resistance
  • testosterone regulated skeletal muscle genes involved in glucose metabolism that led to decreased systemic insulin resistance
  • In the liver, hepatic androgen receptor signaling inhibited development of insulin resistance in mice
  • independent and inverse association of testosterone with hepatic steatosis shown in a cross-sectional study carried out in humans
  • In short, androgen improves insulin resistance by changing body composition and reducing body fat.
  • Although a low serum testosterone level could contribute to the development of obesity and type 2 diabetes through changes in body composition, obesity might also alter the metabolism of testosterone
  • In obese men, the peripheral conversion from testosterone to estrogen could attenuate the amplitude of luteinizing hormone pulses and centrally inhibit testosterone production
  • leptin, an adipokine, has been shown to be inversely correlated with serum testosterone level in men
  • Leydig cells expressed leptin receptors and leptin has been shown to inhibit testosterone secretion, suggesting a role of obesity and leptin in the pathogenesis of low testosterone

      So what is "unequivocal"?
  • Baltimore Longitudinal Study of Aging (BLSA) cohort made up of 3,565 middle-class, mostly Caucasian men from the USA, the incidence of low serum total testosterone increased from approximately 20% of men aged over 60 years, 30% over 70 years, to 50% over 80 years-of-age
  • 30–44% sex hormone binding globulin (SHBG)-bound testosterone and 54–68% albumin-bound testosterone
  • As the binding of testosterone to albumin is non-specific and therefore not tight, the sum of free and albumin-bound testosterone is named bioavailable testosterone, which reflects the hormone available at the cellular level
  • Serum total testosterone is composed of 0.5–3.0% of free testosterone unbound to plasma proteins
  • alterations in SHBG concentration might affect total serum testosterone level without altering free or bioavailable testosterone
  • listed in Table​T
  • A significant, independent and longitudinal effect of age on testosterone has been observed with an average change of −0.124 nmol/L/year in serum total testosterone28. The same trend has been shown in Europe and Australia
  • Asian men residing in HK and Japan, but not those living in the USA, had 20% higher serum total testosterone than in Caucasians living in the USA, as shown in a large multinational observational prospective cohort of the Osteoporotic Fractures in Men Study
  • subjects with chronic diseases consistently had a 10–15% lower level compared with age-matched healthy subjects
  • In Caucasians, the mean serum total testosterone level for men in large epidemiological studies has been reported to range from 15.1 to 16.6 nmol/L
  • Asians, higher values, ranging from 18.1 to 19.1 nmol/L, were seen in Korea and Japan
  • Chinese middle-aged men reported a similar mean serum testosterone level of 17.1 nmol/L in 179 men who had a family history of type 2 diabetes and 17.8 nmol/L in 128 men who had no family history of type 2 diabetes
  • The reduction of total testosterone was 0.4% per year in both groups
  • HK involving a cohort of 1,489 community-dwelling men with a mean age of 72 years, a mean serum total testosterone of 19.0 nmol/L was reported
  • pro-inflammatory factors, such as tumor necrosis factor-α in the testes, could locally inhibit testosterone biosynthesis in Leydig cells47, and testosterone treatment in men was shown to reduce the level of tumor necrosis factor-α
  • In Asians, a genetic deletion polymorphism of uridine diphosphate-glucuronosyltransferase UGT2B17 was associated with reduced androgen glucuronidation. This resulted in higher level of active androgen in Asians as compared to Caucasians, as Caucasians' androgen would be glucuronidated into inactive forms faster.
  • Compared with Caucasians, the frequency of this deletion polymorphism of UGT2B17 was 22-fold higher in Asian subjects
  • Other researchers have suggested that environmental, but not genetic, factors influenced serum total testosterone
  • The basal and ligand-induced activity of the AR is inversely associated with the length of the CAG repeat chain
  • In the European Male Aging Study, increased estrogen/androgen ratio in association with longer AR CAG repeat was observed
  • a smaller number of AR CAG repeat had been shown to be associated with benign prostate hypertrophy and faster prostate growth during testosterone treatment
  • In India, men with CAG ≤19 had increased risk of prostate cancer
  • the odds of having a short CAG repeat (≤17) were substantially higher in patients with lymph node-positive prostate cancer than in those with lymph node-negative disease or in the general population
  • assessing the polymorphism at the AR level could be a potential tool towards individualized assessment and treatment of hypogonadism.
  • In elderly men, there was reduced testicular response to gonadotropins with suppressed and altered pulsatility of the hypothalamic pulse generator
  • a significant, independent and longitudinal effect of age on serum total testosterone level had been observed
  • A significant graded inverse association between serum testosterone level and insulin levels independent of age has also been reported in Caucasian men
  • Low testosterone is commonly associated with a high prevalence of MES
  • most studies showed that changes in serum testosterone level led to changes in body composition, insulin resistance and the presence of MES, the reverse might also be possible
  • MES predicted a 2.6-fold increased risk of development of low serum testosterone level independent of age, smoking and other potential confounders
  • Other prospective studies have shown that development of MES accelerated the age-related decline in serum testosterone level
  • In men with type 2 diabetes, changes in serum testosterone level over time correlated inversely with changes in insulin resistance
  • weight loss by either diet control or bariatric surgery led to a substantial increase in total testosterone, especially in morbidly obese men, and the rise in serum testosterone level was proportional to the amount of weight lost
  • To date, published clinical trials are small, of short duration and often used pharmacological, not physiological, doses of testosterone
  • In the population-based Osteoporotic Fractures in Men Study cohort from Sweden, men in the highest quartile of serum testosterone level had the lowest risk of cardiovascular events compared with men in the other three quartiles (hazard ratio [HR] 0.70
  • low serum total testosterone was associated with a significant fourfold higher risk of cardiovascular events when comparing men from the lowest testosterone tertile with those in the highest tertile
  • Shores et al. were the first to report that low serum testosterone level, including both serum total and free testosterone, was associated with increased mortality
  • low serum total testosterone predicted increased risk of cardiovascular mortality with a HR of 1.38
  • low serum total testosterone increased all-cause (HR 1.35, 95% CI 1.13–1.62, P < 0.001) and cardiovascular mortality (HR 1.25
  • European Association for the Study of Diabetes 2013 suggested there was an inverse relationship between serum testosterone level and acute myocardial infarction
  • Diabetic men in the highest quartile of serum total testosterone had a significantly reduced risk of acute MI when compared with those in the lower quartiles
  • serum total testosterone level in the middle two quartiles at baseline predicted reduced incidence of death compared with having the highest and lowest levels

    Nice review of Testosterone levels and some of the evidence linking Diabetes with low T.  However, the conclusion by the authors regarding what is causing the low T in men with Diabetes is baffling.  The literature does not point to one cause, it is clearly multifactorial--obesity, inflammation, high aromatase activity...I would suggest the authors continue their readings in the manner.
