In the news
According to the American Heart Association (AHA), there is no numerical recommendation of cholesterol intake from food, as the AHA finds no link between dietary cholesterol and cardiovascular risk. Although you have long heard that dietary cholesterol is generally not good for the cardiovascular health, you might be surprised to know the studies have shown no relationship between dietary cholesterol and cardiovascular disease.
Changing dietary recommendations
Based on this and other data, specific dietary cholesterol target recommendations were removed in recent guidelines. It has raised questions about the role of dietary cholesterol with respect to cardiovascular disease. This advisory was developed after a review of human studies on the relationship of dietary cholesterol with blood lipids, lipoproteins, and cardiovascular disease risk to address questions about the relevance of dietary cholesterol guidance for heart health. Evidence from observational studies conducted in several countries generally does not indicate a significant association with cardiovascular disease risk. Learn more...
Analysis: why our traditional understanding about dietary cholesterol was wrong
According to Prab R. Tumpati, MD, founder, WikiMD, and W8MD weight loss, sleep and medspa centers]], founder of W8MD medical weight loss, sleep and medspa and WikiMD, the discrepancy was likely due to the often missed fact that up to 70% of our entire bodies cholesterol is manufactured by the liver in our body from blood sugar and only about 30% comes from the diet.
Inflammation, not cholesterol is key
It is the inflammation that is the risk factor for cardiovascular disease, not as much from cholesterol. Unfortunately, the traditional dietary recommendations assumed that most of our cholesterol in the blood comes from the diet which is not the case. And worse yet, most of the traditional dietary recommendations such as the now withdrawn Food pyramid from the USDA did more harm than good by promoting low fat, low cholesterol but high starchy foods which in turn increased starch (sugar) in our diet, leading to a new problems such as insulin resistance and metabolic syndrome. Since insulin is the hormone that promotes liver production of cholesterol which is the 70% pathway for cholesterol production, strangely, the low cholesterol diet (read high starch diet) leads to what is called insulin resistance which in turn leads to higher insulin levels as a compensation.
This high insulin then causes excess cholesterol production in the liver thus the low fat, low cholesterol traditional food pyramid based diet indirectly contributed to high blood cholesterol, and higher inflammation (via increased belly fat that produces inflammatory cytokines) thus strangely increasing the risk of heart disease.

Current projects
Cardio-oncology is an evolving field in cardiology that provides cardiac care for cancer patients and its survivors. It deals with early detection , reducing the adverse cardiovascular side effects , treating and preventing the cardiovascular effects of cancer therapies , such as radiation , chemotherapy , targeted molecular therapy and newly emerged Immunotherapy.
Leading causes of mortality
Heart disease and cancer are the two main causes of mortality globally, accounting for 46.1% of deaths worldwide.1-2
Due to current advancement in cancer treatment, there has been decrease in mortality in cancer patients. However, the cancer therapy-related cardiovascular complications are a major cause of morbidity and mortality in people living with or surviving cancer. Cancer related cardiovascular complications are in particular chemo-therapy and radiation therapy-induced cardio toxicitiesRead more on Cardio-oncology

Back pain
Pain the back or back pain, is a common health problem affecting 8 out of 10 people at some point during their lives. Back pain can range from a dull, constant ache to a sudden, sharp pain. Acute back pain comes on suddenly and usually lasts from a few days to a few weeks. Back pain is called chronic if it lasts for more than three months. Most back pain goes away on its own, though it may take awhile. Taking over-the-counter pain relievers and resting can help. However, staying in bed for more than 1 or 2 days can make it worse. If your back pain is severe or doesn't improve after three days, you should call your health care provider. You should also get medical attention if you have back pain following an injury. Sometimes it can come on suddenly—from an accident, a fall, or lifting something heavy. In other cases, it can develop slowly due to age-related changes to the spine. Treatment for back pain depends on what kind of pain you have, and what is causing it. It may include hot or cold packs, exercise, medicines, injections, complementary treatments, and sometimes surgery.
Who Gets Back Pain?
Although anyone can have back pain, a number of factors increase your risk. They include:
- Age: Back pain becomes more common with age, with the first attack typically between ages 30 and 40.
- Fitness level: Back pain is more common among people who are not physically fit. For example, weak back and stomach muscles may not properly support the spine. Back pain is also more likely if you exercise a lot after being inactive for a while.
- Diet: A diet high in calories and fat, combined with an inactive lifestyle, can lead to obesity. This can put stress on the back.
- Heredity: Genetics play a role in some disorders that cause back pain.
- Race: African American women are more likely than white women to develop spondylolisthesis, a condition in which bones in the lower spine slip out of place. Learn more
Wiki is the way to go for Medicine
According to Peter Frishauf, founder of Medscape, something like Wikipedia For Medicine is The Future! "For readers, Wikipedia is a win. In traditional publishing, readers must wade through many articles on a subject, each written by a few experts, published at 1 moment in time. In Wikipedia you read 1 living article written by many, continually updated by many. Who needs 50 articles on avian flu when 1 will do? And Wikipedia content is often the best on the Web, which means the best anywhere. For writers, Wikipedia offers neither authorship, recognition, reward, nor punishment. Articles aren't indexed, but with Google and Yahoo!, who needs it? The motivation for writing is love of information and a desire to share it. I say a variant of Wikipedia for medicine is the future -- and it's good."
The vision of WikiMD is exactly that! I.e. To be a comprehensive and free source of medical information for all with articles on everything related to medicine and linking everything related to health on the internet. Join us in this unique effort and contribute to wikiMD.
