Elderly men over 65 years of age with late-onset hypogonadism benefit as much from test... - 0 views

  • The benefits of restoring serum testosterone in men with LOH were not significantly different between men older than 65 years of age and younger men. There were no indications that side effects were more severe in elderly men. The effects on prostate and urinary function and hematocrit were within safe margins.
  • obesity, but also impaired general health, are the more common causes of low testosterone in aging men
  • Severe LOH is associated with substantially higher risks of all-cause and cardiovascular mortality,
  • ...30 more annotations...
  • advanced age, obesity, a diagnosis of metabolic syndrome, and poor general health status were predictors of LOH
  • Diabetes mellitus was correlated with hypogonadism in most studies
  • coronary heart disease, hypertension, stroke, and peripheral arterial disease did not predict hypogonadism, they did correlate with the incidence of low testosterone
  • LOH can be defined by the presence of at least three sexual symptoms associated with a total testosterone level of less than 11 nmol/L (3.2 ng/mL) and a free testosterone level of less than 220 pmol/L (64 pg/mL)

      the European Male Aging study defined low T as total < 320 ng/dl and free < 64 pg/ml.  
  • Mean weight decreased
  • Waist circumference decreased
  • Total cholesterol decreased
  • Low-density lipoprotein decreased
  • Triglycerides decreased
  • High-density lipoprotein (HDL) increased
  • ratio of total cholesterol to HDL improved
  • Prostate volume increased
  • PSA increased
  • The benefits for men older than 65 years of age were compared with those of younger men, and the improvements in body weight, metabolic factors, psychological functioning, and sexual functioning were of the same magnitude in both age groups
  • weight loss was progressive over the 6-year period, effects of testosterone on lipids and on psychological and sexual functioning reached a plateau after approximately 3 years and these effects were sustained
  • Effects of testosterone on hematopoiesis, on the prostate, and on bladder function were not more severe in older men than in younger men
  • observe a mild increase in prostate volume and serum PSA over time, which is a normal finding in aging men. Maybe somewhat surprising, postvoiding residue and the IPSS did not deteriorate with aging but showed a degree of improvement
  • the severity of the metabolic syndrome is associated with the severity of lower urinary tract symptoms
  • The symptoms of the metabolic syndrome improve upon testosterone treatment and testosterone may thus have a favorable effect on lower urinary tract symptoms
  • it seems reasonable to conclude that the risks of testosterone administration to elderly men are not disproportionately higher in elderly men than in younger men.
  • Despite evidence to the contrary, physicians still harbor a wrongful association between testosterone and the development of prostate pathology (prostate cancer and benign prostate hyperplasia)
  • Not surprisingly, the incidence of prostate cancer was higher in older men; however, it was lower than expected in both groups
  • These observations suggest that the incidence of prostate cancer in patients receiving testosterone therapy, both in the younger and in the older group, was not greater than in the general population not receiving testosterone treatment
  • The historical fear that raising testosterone levels will result in more prostate cancer has been dispelled, particularly by the work of Abraham Morgentaler
  • Higher serum testosterone levels fail to show an increased risk of prostate cancer, and supraphysiological testosterone does not increase prostate volume or PSA in healthy men
  • This apparent paradox is explained by the "saturation model,"
  • Recent studies indicate no increased risk of prostate cancer among men with serum testosterone in the therapeutic range
  • In the present observational study, no cases of major adverse cardiovascular events occurred.
  • the benefits of testosterone therapy are fully achieved only by long-term treatment
  • To achieve maximal benefits, good patient adherence is a prerequisite
  •  
    Study finds new difference in Testosterone benefits and/or side effects between men < 65 with low T and men > 65 with low T.

Treatment of Men for "Low Testosterone": A Systematic Review - 0 views

  • Of 47 studies that assessed sexual function or satisfaction, 23 studies reported beneficial effects of testosterone treatment for at least 1 measure of sexual function or satisfaction,[6, 26, 35, 37, 40, 43–60] and 24 studies did not show testosterone-associated improvements in any sexual function endpoint
  • Of 31 studies that evaluated erectile function, 15 found no improvement with testosterone therapy
  • Twelve studies included men with ED; 8 found no benefit of testosterone over placebo
  • ...2 more annotations...
  • Of 23 studies that specifically reported changes in libido, 13 found that testosterone treatment increased libido,[26, 35, 37, 45, 46, 54, 56, 60, 63, 65, 70, 77, 79] eight found no effect,
  • Eleven studies used the Aging Males’ Symptoms scale, which includes 3 questions on libido and sexual function. Five studies found no difference between testosterone and placebo on total scores,[26, 54, 57, 72, 76] and 4 studies found a benefit of testosterone
  •  
    A systemic review of Testosterone benefit in men stirs the pot.  I can't say that I agree with the majority of their conclusions.  What I do agree with them on is that the majority of men on Testosterone therapy likely don't need it and are simply using Testosterone as a drug.

Sexual Function in Older Women After Oophorectomy : Obstetrics & Gynecology - 0 views

  •  
    Here is my problems with "statistics".  The statement "No significant difference in the report of sexual ideation was found..."  If you are the one women that had decreased sexual function after having your ovaries removed: isn't it comforting to know you are not statistically significant.  Come on.  Some did, and that is enough and should be considered significant.  This is a permanent change to these woman's lives and marriage.

Plasma lipoproteins: composition, structure and biochemistry - 0 views

  • triacylglycerols
  • The most abundant lipid constituents are triacylglycerols, free cholesterol, cholesterol esters and phospholipids (phosphatidylcholine and sphingomyelin especially ), though fat-soluble vitamins and anti-oxidants are also transported in this way
  • the lipoprotein aggregates should be described in terms of the different protein components or apoproteins (or 'apolipoproteins'
  • ...8 more annotations...
  • Density is determined largely by the relative concentrations of triacylglycerols and proteins and by the diameters of the broadly spherical particles
  • these classes can be further refined by improved separation procedures, and intermediate-density lipoproteins (IDL) and subdivisions of the HDL (e.g. HDL1, HDL2, HDL3 and so forth
  • the main groups are classified as chylomicrons (CM), very-low-density lipoproteins (VLDL), low-density lipoproteins (LDL) and high-density lipoproteins (HDL), based on the relative densities of the aggregates on ultracentrifugation
  • the various lipid components should not be considered as absolute, as they are in a state of constant flux
  • Apo A1 is the main protein component of HDL
  • Apo A2 is the second most important HDL apolipoprotein
  • Lipoproteins are spherical (VLDL, LDL, HDL) to discoidal (nascent HDL) in shape with a core of non-polar lipids, triacylglycerols and cholesterol esters, and a surface monolayer, ~20Å thick, consisting of apoproteins, phospholipids and non-esterified cholesterol, which serves to present a hydrophobic face to the aqueous phase
  • The lipoproteins can be categorised simplistically according to their two main metabolic functions. The principal role of the chylomicrons and VLDL is to transport triacylglycerols ‘forward’ as a source of fatty acids from the intestines or liver to the peripheral tissues. In contrast, the HDL remove excess cholesterol from peripheral tissues and deliver it to the liver for excretion in bile in the form of bile acids (‘reverse cholesterol transport’). While these functions are considered separately here for convenience, it should be recognised that the processes are highly complex and inter-related, and they involve transfer of apoproteins, enzymes and lipid constituents among the heterogeneous mix of all the lipoprotein fractions.

Effect of Testosterone Replacement Therapy on Cognitive Performance and Depression in M... - 0 views

  • Azad et al [15] used single photon emission computed tomography and showed that, after 3~5 weeks of TRT, cerebral perfusion was increased in the midbrain and the superior frontal gyrus in seven men with hypogonadism
  • After 12~14 weeks, increased perfusion was still observed in the midbrain as well as in the midcingulate gyrus
  • TDS patients who received TRT showed significant improvement in cognitive function only if mild cognitive impairment was present at baseline
  • ...4 more annotations...
  • Cherrier et al [17] evaluated a sample of 32 subjects, which included 17 men with mild cognitive impairment and 15 with Alzheimer's disease. At the 6-week follow-up, patients who received TRT showed significantly better scores regarding spatial memory, constructional abilities, and verbal memory compared to those noted in the placebo group. Taken together, these results suggest that TRT has a beneficial effect on cognitive function
  • TRT improved mood and well-being, and reduced fatigue and irritability in hypogonadal men
  • The study by Pope et al [20] involved men with depression refractory to standard anti-depressants, and found that TRT lowered the Hamilton Depression score,
  • depression tends to increase as testosterone levels decrease [21], it is highly likely that TRT improved symptoms of depression by increasing testosterone levels.

Chronic Testosterone Replacement Exerts Cardioprotection against Cardiac Ischemia-Reper... - 0 views

  • In this study, the cardioprotective effects of testosterone in testosterone-deprived rats heart with I/R injury were demonstrated
  • Prior to I/R injury, testosterone replacement provided cardioprotective effects in testosterone-deprived rats as indicated by (1) improved cardiac functions by markedly preserved %EF and %FS, and (2) attenuated cardiac sympathovagal imbalance by a markedly decreased LF/HF ratio
  • Testosterone replacement exerts cardioprotective effects by improving left ventricular function and cardiac sympathovagal balance impaired by testosterone deprivation in ORX rats
  • ...3 more annotations...
  • During the I/R period, testosterone replacement in ORX rats exerted the beneficial effects as indicated by (1) improved left ventricular pressure; (2) markedly decreased infarct size; (3) reduced fatal cardiac arrhythmias by increased time to 1st VT/VF onset and reduced arrhythmia scores; and (4) attenuated cardiac mitochondrial dysfunction caused by I/R injury by reducing ROS production, cardiac mitochondrial swelling and mitochondria membrane depolarization.
  • Chronic testosterone replacement also ameliorates left ventricular dysfunction, and reduces the infarct size and cardiac arrhythmias impaired by I/R injury under testosterone-deprived conditions
  • The mechanisms responsible for these beneficial effects of testosterone could be due to its ability to attenuate cardiac mitochondrial dysfunction and cardiomyocyte apoptosis
  •  
    animal study finds that Testosterone therapy is cardioprotective in a preventative mode and with myocardial injury.  Normalization of Testosterone in these animals with low T reduced infant injury size and improved heart function.
