Testosterone Dose-Response Relationships with Cardiovascular Risk Markers in Androgen-Deficient Women: A Randomized, Placebo-Controlled Trial: The Journal of Clinical Endocrinology & Metabolism: Vol 0, No 0 - 0 views

  •  
    Study finds no worsening in cardiovascular biomarkers in women on Testosterone.  The women in this study were chose due to low Testosterone.  Testosterone was given IM at 4 different doses.  This is in contrast to other studies that have looked at endogenous Testosterone level.  Studies have shown increasing endogenous T levels in women is associated with increased CVD.  Studies on exogenous are lacking.  This points to limited risk associated with CVD and T therapy in women.   One caveat.  Two of the authors of this study have ties to the maker of the Testosterone enanthate used in this study.  Why is this important?  Prior studies have shown significant decrease in adverse event reporting in those funded by pharma--bias.

Short-term testosterone therapy failed to increase CV risk in women | Endocrinology - 0 views

  •  
    24 week study of 71 women post-hysterectomy finds no increase in cardiovascular biomarkers.  Several problems with this study.  First, there was a large drop out--24%.  Second and most important, the women were pretreated with estrogen prior to Testosterone therapies were initiated.  Other studies have proposed that this protects cardiovascular risk in women on Testosterone.  Previous studies show increasing endogenous Testosterone is associated with increasing cardiovascular disease in women.   This study would be much better if no estradiol was prescribed.  That would give an unbiased view of Testosterone in post-hysterectomy women.  Not much can be taken from this study. If you doctor doesn't know this, find another doctor.  Inherent bias in this study as ties to the manufacturer of the Testosterone was disclosed. This study point to the inherent flaws in so much of the medical literature today.  Most would read the headlines and read no further, but the "further" dispels the headline as flawed.

Frequency and level of evidence used in recommendations by the National Comprehensive Cancer Network guidelines beyond approvals of the US Food and Drug Administration: retrospective observational study | The BMJ - 0 views

  •  
    Just the facts: US National Comprehensive Cancer Network (NCCN) recommendations often lack evidence, but financial ties of the NCCN members that create the guidelines do not. I think it is time to start calling out the lack of evdience of some of the so-called creators of evidence-based guidelines.

Hypoxia Regulates Insulin Receptor Substrate-2 Expression to Promote Breast Carcinoma Cell Survival and Invasion | Cancer Research - 0 views

  •  
    IRS-2 expression, but not IRS-1 expression, is increased by hypoxia (HIF-1alpha), which selects for tumor cells with increased metastatic potential. IRS-2 is active to mediate insulin-like growth factor I-dependent signals in hypoxia, and enhanced activation of Akt in hypoxia is dependent on IRS-2 expression. It is Akt that increases insulin receptor expression. This ties hypoxia to increase in insulin signaling and insulin receptor expression. Boom!

Regulation of 11beta-HSD genes in human adipose tis... [Obes Res. 2004] - PubMed - NCBI - 0 views

  •  
    adipocytes increase genetic expression of 11beta-HSD. This increases local cortisol production from cortisone.  This plays a pivotal role in obesity.  Question:  would this play a role in peripheral hypothyroid?  I think so.

Golden Motor Electric Wheelchair - 0 views

  •  
    Powerchairs are generally four-wheeled or six-wheeled and non-folding, however some folding designs exist and other designs may have some ability to partially dismantle for transit. Four general styles of powerchair drive systems exist: front, centre or rear wheel drive and all-wheel drive. Powered wheels are typically somewhat larger than the trailing/castoring wheels, while castoring wheels are typically larger than the castors on a manual chair. Centre wheel drive powerchairs have castors at both front and rear for a six-wheel layout. Angel Wheelchair Electric standing wheelchair Standing up, driving function by power. Head and signal light (controlled by joystick). Adjustable headrest. Adjustable footplate. Detachable backrest Rigid steel framework W/liquid coating Flip-backward armrest Max speed: 9.15KM/H Front castor: 2.80/2.50-4 pneumatic castor (9") Rear wheels: 3.00-8 pneumatic tire (14") Available seat width: A (46 cm), D (42 cm) Max loading: A size: 135 kg Net weight w/o battery: 62.7 kg A powerchairs is a wheelchair that is propelled by means of an electric motor rather than manual power. Power wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for distances or over terrain which would be fatiguing in a manual wheelchair. They may also be used not just by people with 'traditional' mobility impairments, but also by people with cardiovascular and fatigue based condition. An powerwheelchair powers more than just chair. It gives the power to safely travel long distances on own. It empowers to navigate through home, backyard, school, workplace or local park. It gives power to do the things,want to do. It gives power. When accidents occur that leave permanent leg injuries, or as age sets in and joint pain becomes unbearable, the power chair acts as a gateway to continue living life to the fullest. The powerwheelchairs in our lineup are all battery powered, yet each device fills

  • the benefit of cytotoxic chemotherapy may have been overestimated for cancers of oesophagus, stomach,rectum and brain.
  • this reflects the presentation of results as a ‘reduction in risk’ rather than asan absolute survival benefit[89,90]and by exaggerating theresponse rates by including ‘stable disease’
