    What is "evidence-based medicine"?   Most recommendations and clinical practices are based on the lowest level of evidence: essentially opinion-based therapy.

  • For all TT prescription subjects combined, the post/pre prescription rate ratio for MI (RR)was 1.36
  • In men aged 65 years and older the RR was 2.19 (1.27, 3.77), while in men under age 65 years the RR was 1.17
  • increasing RR with increasing age.
  • ...20 more annotations...
  • The RRs were 0.95 (0.54, 1.67) under 55 years
  • 1.35 (0.77, 2.38) at 55–59
  • 1.29 (0.71, 2.35) at 60–64,
  • 1.35 (0.44, 4.18) at 65–69, 1.62
  • 3.43 (1.54, 7.66) at 75 years and older
  • The adjusted post/pre RR for PDE5I across all ages was 1.08
  • For TT prescription, in men under age 65 years, the RR was 2.90 (1.49, 5.62) for those with a history of heart disease and 0.90 (0.61, 1.34) for those without
  • In men aged 65 year and older, the RR was 2.16 (0.92, 5.10) for those with a history of heart disease and 2.21 (1.09, 4.45) for those without.
  • Among men aged 65 years and older, we observed a two-fold increase in the risk of MI in the 90 days after filling an initial TT prescription
  • Among younger men with a history of heart disease, we observed a two to three-fold increased risk of MI in the 90 days following an initial TT prescription and no excess risk in younger men without such a history
  • Among older men, the two-fold increased risk was associated with TT prescription regardless of cardiovascular disease history
  • our own findings appear consistent with a higher frequency of thrombotic events following TT prescription among men with more extensive coronary vascular disease.
  • Our findings are consistent with a recent meta-analysis of placebo-controlled randomized trials of testosterone therapy lasting 12 or more weeks among mainly older men, which reported that testosterone therapy increased the risk of adverse cardiovascular-related events (OR = 1.54, 95%CI:1.09, 2.18), as well as serious adverse cardiovascular-related events (OR = 1.61, 95%CI:1.01, 2.56) which included myocardial infarction along with other conditions
  • This association appeared unrelated to average baseline testosterone level (p = 0.70) but varied by source of funding (p = 0.03), with a stronger summary effect in a meta-analysis of studies not funded by the pharmaceutical industry (OR = 2.06, 95%CI:1.34, 3.17) compared with studies funded by the pharmaceutical industry

      This supports prior analysis that studies done by pharmaceutical corps will be more favorable to their product(s) than those independently funded.  This is called bias.
  • the evidence supports an association between testosterone therapy and risk of serious, adverse cardiovascular-related events–including non-fatal myocardial infarction–in men
  • there is some evidence that low endogenous testosterone levels may also be positively associated with cardiovascular events
  • effects of endogenous and exogenous testosterone may differ. Exogenous testosterone (TT) is associated with physiologic changes that predispose to clotting and thrombotic disorders including increased blood pressure [18], polycythemia [19], reductions in HDL cholesterol [18], [20], and hyperviscosity of the blood and platelet aggregation. [20]–[23]; TT also increases circulating estrogens [24], [25] which may play a role in the observed excess of adverse cardiovascular-related events, given that estrogen therapy has been associated with this excess in both men and women
  • did not include information on the serologic or diagnostic indications for treatment.
  • no association between PDE5I prescriptions and the risk of MI
  • Recently TT has been increasing extraordinarily rapidly, including among younger men and among those without hormone measurement

    There are alot of problems with evidence-based medicine.  Don't for one minute think that a "study" can be without major flaws and biases.  In fact, alot  of the studies reported by the press are based on poorly designed and manipulated studies.  Probably 50% of the studies that I read I disgard after evaluating the study design and statistics.

  • consumption of this particular diet for at least a 2-month period helped to reduce the outcomes of both acute and chronic inflammation induced by LPS.
  • chronic inflammation compromised both glucose and insulin tolerance, which is normally seen in certain chronic metabolic diseases
  • LPS resulted in an increase in neopterin levels, which is a marker for immune system activation
  • ...6 more annotations...
  • diet enriched in fruits and vegetables (and consequently phytochemicals) was able to reverse the process and maintain and even elevate insulin sensitivity and glucose tolerance
  • LPS-mediated effects are related to an increase in TLR4 levels that triggers the activation of nuclear factor-kB (NF-kB), a transcription factor that activates a cascade of inflammatory mediators [41]. These factors control the transcription of inflammatory mediators, such as IL-1β, IL-6, TNF-α, TNF-β, INF-α, INFβ, INF-γ
  • Inflammation can alter insulin action and give rise to diabetes and obesity by blocking insulin receptor downstream events, impairing insulin receptor substrate 1 (IRS-1) activation and phosphatidylinositol 3-kinase-dependent (PI3K) pathways, therefore compromising insulin signaling
  • systemic inflammation (generated by LPS) also increased neopterin levels in the urine and resulted in altered neuronal activity by decreasing dopamine (DA) metabolism
  • an increase in neopterin levels has been recognized a sensitive biomarker for immune system activation
  • Our experiments denoted that these diets were able to diminish inflammatory mediators and oxidative damage

    low exposure to glyphosate-based herbicide (round up) decreases Testosterone production by 35%.   This occurs at very low exposure levels of 1 ppm.  In a rat study, large doses causes ACUTE rat TESTICULAR TOXICITY. I think both men and women should be very careful around this chemical

  • TLRs are functionally inducible and associated with downstream NF-B activation and proinflammatory cytokine production.
  • TLRs represent a family of receptors that are critical to the innate immune response against foreign pathogens and microorganisms
  • LPS has been shown to induce proinflammatory chemokine gene expression in differentiated human adipocytes through TLR and NF-B action
  • ...2 more annotations...
  • Stimulation of TLRs initiates intracellular signaling cascades resulting in downstream NF-B and mitogen-activated protein kinase activation and production of proinflammatory chemokines associated with mechanisms of metabolic dysfunction and cardiovascular disease progression.
  • Elevated fatty acids levels associated with obesity activate TLR4 signaling in fat cells and macrophages, and induce insulin resistance in murine models
  • Nathan Goodyear on 19 Jan 12
     
    TLR, especially TLR-4, is directly involved in NF-KappaB activation and release of inflammatory cytokines

  • Cisplatin and 5-FU or CAP (cisplatin, doxorubicin, and cyclophosphamide) regimens can be used for combination chemotherapy
  • patients with advanced salivary gland malignancy treated with the CAP regimen achieved partial response (PR) or stable disease (SD) rates of 67% (8 out of 12 patients)
  • Agents commonly given as monotherapy for treating ACC are cisplatin, mitoxantrone, epirubicin, vinorelbine, paclitaxel, and gemcitabine. However, few of these agents have shown efficacy
  • ...23 more annotations...
  • single agent mitoxantrone or vinorelbine were recommended as reasonable choices
  • ACC is subdivided into 3 histological groups based on solid components of the tumor including cribriform, tubular, and solid
  • Cribriform and tubular ACCs usually exhibit a more indolent course, whereas the solid subtype is associated with worse prognosis
  • ACC consists of two different cell types: inner luminal epithelial cells and outer myoepithelial cells
  • epithelial cells express c-kit, cox-2 and Bcl-2
  • myoepithelial cells express EGFR and MYB
  • a balanced translocation of the v-myb avian myeloblastosis viral oncogene homolog-nuclear factor I/B (MYB-NFIB) is considered to be a signature molecular event of ACC oncogenesis
  • As a transcription factor, MYB is known to modulate multiple genetic downstream targets involved in oncogenesis, such as cox-2, c-kit, Bcl-2 and BclX
  • Various signaling cascades are essential for cancer cells to survive and grow. The PI3K/Akt/mTOR pathway is one of them
  • This pathway regulates cell survival and growth and is upregulated in many cancers
  • Mutations in genes associated with DNA repair are frequently found in familial cancer syndromes, such as hereditary breast-ovarian cancer syndrome (HBOC), hereditary non-polyposis colorectal cancer (HNPCC, also called Lynch syndrome) and Li-Fraumeni syndrome [30, 31]. These mutations were also reported in non-hereditary cancers
  • 70% of ACC samples (58 of 84) were found to have genetic alterations in the MYB/MYC pathway, indicating that changes in this pathway are crucial in ACC pathogenesis
  • The second most frequently mutated pathway was involved in chromatin remodeling (epigenetic modification), a pathway that includes multiple histone related proteins, and was altered in 44% of samples
  • C-kit
  • VEGF, iNOS and NF-κB were noted to be highly expressed in ACC cells as compared to normal salivary gland cells
  • members of the SOX family, such as SOX 4 and SOX10, are overexpressed in ACC
  • FABP7 (Fatty acid binding protein 7) and AQP1 (Aquaporin 1) tend to be overexpressed in ACC cell lines
  • considerable variability in HER2 overexpression ranging from 0–58% in patients with ACC
  • the study with cetuximab and concurrent chemoradiation or chemotherapy showed the highest ORR (total 43%, 9.5% CR and 33% PR), but this regimen was only given to the EGFR positive patients
  • Cancer immunotherapy can be classified into 3 major groups. Active immunization using anti-tumor vaccines to induce and recruit T cells, passive immunization based on monoclonal antibodies, and adoptive cell transfer to expand tumor-reactive autologous T cells ex vivo and then reintroduce these cells into the same individual
  • LAK cells showed cytotoxicity against ACC cells
  • cytokine-induced cell apoptosis and the cytotoxic effect of the LAK cells contributed to tumor regression
  • molecular finding of the MYB-NFIB fusion gene has the greatest potential to target what appears to be a fundamental event in disease pathogenesis
