Sorry for the long absence of posting, I just needed a media break.
Below is a review of a very interesting study showing that in mice who had aggressive breast cancer ANY surgery caused an increase in tumor activity. Use of NSAIDs-drugs such as Ibuprofen, lowered this effect, though did not eliminate the risk. This is important in decision making for all non essential surgery after a cancer diagnosis. It also informs the possible use of NSAIDs in the setting of any post cancer diagnosis surgery.
Surgery Might Promote Growth of Metastases
Anthony L. Komaroff, MD reviewing Krall JA et al. Sci Transl Med 2018 Apr 11.
In a mouse model, surgery of any type promoted growth of tumor cells at secondary locations.
Clinical lore says that resection of a primary tumor can cause previously inapparent metastatic deposits to flare. In a mouse model of breast cancer, researchers tested whether and how this phenomenon might occur.
In a series of experiments in 273 mice that had not developed breast cancer naturally, aggressive mouse breast cancer cells were implanted in various locations (i.e., “pseudo-metastases”). Initially, the tumor cells grew, but then they entered a period of dormancy. This dormancy occurred only in mice with intact immunity, not in immunodeficient mice, which suggests that the immune system contains (but doesn't eliminate) pseudo-metastases. Surgery of any type (not just resection of a primary tumor) led to the aggressive growth of pseudo-metastases in 60% of animals, compared with 10% of control animals that did not undergo surgery. Surgical procedures caused systemic inflammatory responses: Activated monocytes from the marrow traveled to the sites of the pseudo-metastases and became tumor-associated macrophages. These macrophages suppressed the immune system near the tumor, thereby awakening the pseudo-metastases from their dormancy. Treating the animals with nonsteroidal anti-inflammatory drugs before and immediately following surgery greatly attenuated growth of pseudo-metastases. ... See MoreSee Less
It is not 'All in your head" if you are experiencing withdrawal symptoms when you try and stop anti-depressants. "Discontinuation syndrome" as they prefer it to be called, is common.
"The drugs initially were approved for short-term use, following studies typically lasting about two months. Even today, there is little data about their effects on people taking them for years, although there are now millions of such users."
I have seen them be very helpful in the short term. But often difficult to stop, and sadly they are way too often prescribed. ... See MoreSee Less
A very interesting article. If you can stay with the very confusing chart you will see that high fiber diets result in LESS food absorption --less fat and overall nutrient intake (this sounds bad, but it all about balance) thus less weight gain. Along the way it improves insulin and gut health-impacting your immune system positively.
Many know that I have been advocating a low carb diet for mid life and beyond women. It is truly an elegant way to lose weight and enjoy fat....However, I have found it very difficult to eat adequate fiber. I am sure one could do so, but I found it difficult. In the absence of adequate fiber, constipation is commonly a problem on the low carb diet. Clearly inadequate fiber has many other health risks as are well documented in this article.
I have came back full circle. Life is ever humbling. While I think fat is important in the diet, I do believe that small amounts of healthy fats--Olive oil (good quality), fish oils (non polluted), eggs (not commercial) and quality dairy products (ideally raw and hormone free) are adequate. Focus your diet on veggies, legumes, fruit, whole grain bread, and whole grains-rice/barley etc. With some additional healthy fish,lean meats as healthy as you can afford (hormone and antibiotic free poultry and grass fed beef as a base and ideally local and free range as you can afford).
If weight loss is an objective, reign in the quantity of bread, grains and fats (but you need some fat, just not lots). If you need guidance and structure, I do believe that the current Weight Watchers recommendations are solid. They are recommending unlimited veggies and fruits, lean poultry and eggs with controls on the the rest--cutting out excess grains, sugar and fats.
It's not rocket science, but at times it sure feels like it... ... See MoreSee Less
