This weeks thoughts….

This is one of the best descriptions of depression I’ve read….

When you have depression it’s like it snows every day.

Some days it’s only a couple of inches. It’s a pain in the ass, but you still make it to work, the grocery store. Sure, maybe you skip the gym or your friend’s birthday party, but it IS still snowing and who knows how bad it might get tonight. Probably better to just head home. Your friend notices, but probably just thinks you are flaky now, or kind of an asshole. Some days it snows a foot. You spend an hour shoveling out your driveway and are late to work. Your back and hands hurt from shoveling. You leave early because it’s really coming down out there. Your boss notices. Some days it snows four feet. You shovel all morning but your street never gets ploughed. You are not making it to work, or anywhere else for that matter. You are so sore and tired you just get back in the bed. By the time you wake up, all your shoveling has filled back in with snow. Looks like your phone rang; people are wondering where you are. You don’t feel like calling them back, too tired from all the shoveling. Plus they don’t get this much snow at their house so they don’t understand why you’re still stuck at home. They just think you’re lazy or weak, although they rarely come out and say it. Some weeks it’s a full-blown blizzard. When you open your door, it’s to a wall of snow. The power flickers, then goes out. It’s too cold to sit in the living room anymore, so you get back into bed with all your clothes on. The stove and microwave won’t work so you eat a cold Pop Tart and call that dinner. You haven’t taken a shower in three days, but how could you at this point? You’re too cold to do anything except sleep. Sometimes people get snowed in for the winter. The cold seeps in. No communication in or out. The food runs out. What can you even do, tunnel out of a forty foot snow bank with your hands? How far away is help? Can you even get there in a blizzard? If you do, can they even help you at this point? Maybe it’s death to stay here, but it’s death to go out there too. The thing is, when it snows all the time, you get worn all the way down. You get tired of being cold. You get tired of hurting all the time from shoveling, but if you don’t shovel on the light days, it builds up to something unmanageable on the heavy days. You resent the hell out of the snow, but it doesn’t care, it’s just a blind chemistry, an act of nature. It carries on regardless, unconcerned and unaware if it buries you or the whole world. Also, the snow builds up in other areas, places you can’t shovel, sometimes places you can’t even see. Maybe it’s on the roof. Maybe it’s on the mountain behind the house. Sometimes, there’s an avalanche that blows the house right off its foundation and takes you with it. A veritable Act of God, nothing can be done. The neighbors say it’s a shame and they can’t understand it; he was doing so well with his shoveling.



The difference between fermented and unfermented forms of soy protein and their benefits in prostate cancer is an interesting topic with varied research indicating different results.… As noted above recent research indicates that unfermented soy is associated with a decreased risk of PCa while fermented soy shows no associations with risk (Applegate et al., 2018) tempering earlier research that fermented soy may increase risk and cancer progression.

Why the difference between fermented and unfermented varieties? My readings found that, firstly, fermentation sees bacterial β-glucosidases cleave glycosidic linkages akin to digestive enzymes and gut microbiota altering soys structure (Islam et al., 2014). Secondly, a mechanism by which isoflavones exert anticarcinogenic effects is attributed to their antioxidant properties decreasing lipid peroxidation and oxidative DNA damage. Fermented soy generally contains added salt which with fermentation, the loss of oxygen and addition of acid, is causal to antioxidant property loss (Kim et al., 2011).

Contrary to the theory that fermented varieties show no association with risk, prior research indicates that fermented soy may contain nitroso compounds and high nitrate levels. Akin to their association with gastric cancer and via damage to stomach lining (increased permeability) and elevated endogenous N-nitroso formation (Kim et al., 2011) potential association with other forms of cancer including prostate cancer are thought to exist (Wu, Wang, Ho, & Giovannucci, 2013). It is theorised that nitrate may impact prostate cancer tissues where low pH/hypoxic conditions occur (Wu et al., 2013). That is, the conversion of nitrate to nitrite to NO occurs or does not occur as the case may be depending on ph/hypoxic conditions thus either facilitating inflammatory cancer conditions or antitumor effects (Wu et al., 2013)

Playing devil’s advocate even further, recent research also tends to suggest an alternative risk analysis with higher intakes of total isoflavones (genistein, daidzein and glycitein) potentially associated with an increased risk of prostate cancer advancement (Reger, Zollinger, Liu, Jones, & Zhang, 2018).

Research indicates that genistein intervention induces modulation of several genes (NOTCH3, JAG1, ADCY4, NEU1) involved in cell cycle, angiogenesis, immune response and intracellular signal transduction (Bilir et al., 2017). It is thought these genes potentialize molecular targets of genistein in prostate cancer pathways and prostate tumorigenesis (Bilir et al., 2017). This is seemingly further ratified by Reger et al., 2018 (n=27,004) who note that genistein may promote proliferation and metastasis of patient-derived prostate cancer cells by increasing epidermal growth factor receptor phosphorylation. Genistein is  also thought involved in G2/M cell cycle arrest activation and directs its effects at proteins involved in G2/M cancer checkpoints (Mukund, Mukund, Sharma, Mannarapu, & Alam, 2017).

Similarly, Reger et al., 2018 indicate that phytoestrogens may induce an estrogenic response due to structural similarity to 17β-estradiol (Reger et al., 2018) where estrogenic prostate carcinogenesis and prostate cancer progression (especially aggressive forms) manifests in genotoxic metabolites and regulation of estrogen receptor-β expression (Reger et al., 2018). In this instance it is thought the isoflavone daidzein may be causal to prostate cancer advancement due to estrogenic effect on the prostate gland (Reger et al., 2018).

This tends to indicate that potential benefits of soy and soy isoflavones is dependent on the stage and aggressiveness of the cancer and whether it’s application is for the prevention of or treatment of prostate cancer… In this, other recent studies suggest the timing of soy protein intake may impact prostate cancer potential more than the intake of soy itself. Bilir et al., 2017, indicate that higher soy intake during puberty when the prostate undergoes androgen-induced growth is likely more effective in prevention of prostate cancer than soy intake post diagnosis.
