Why It Is Dangerous to Ignore Infections

By Hui Xie-Zukauskas

Pathogens_comboWith the arrival of warmer weather and summer, people get active, and so do lots of bacteria and pathogens. This is important to remember whenever you are on vacation or just enjoying the outdoors. And it is why I want to emphasize the danger of infections and the value of prevention.

Infections are everywhere and occur in many types, including flu, food poisoning, tick-borne Lyme disease, and any form of -itis (e.g., meningitis and hepatitis). The consequences of infections vary too, from a temporary harmful or sick condition to long-term diseases and disorders.

Evidence is mounting that infectious agents (e.g., bacteria and viruses) can lead to cancer. Here I’d like to highlight the role of infection in cancer and, to some extent, in chronic illnesses such as Alzheimer’s disease.

Role of bacteria in cancer

There is a significant association between bacterial infection and cancer. For example, the following bacteria are responsible for an increased risk of certain cancers:

-          Helicobacter pylori is linked to stomach cancer

-          Chlamydia pneumonia, to lung cancer

-          Chlamydia infection, to ovarian cancer and cervical cancer

-          Neisseria Gonorrhoeae, to bladder, ovarian, and prostate cancer

Notably, some bacteria strains—specifically, Bacteroides fragilis and Escherichia coli—are involved in developing colon cancer, especially the hereditary type. This is because the two strains can bypass the gut barrier, which acts as an intestinal guardian, and reach the epithelial cells (cells that line the insides of organs, including the gastrointestinal tract), turning these cells cancerous.

Role of viruses in cancer

A growing body of knowledge indicates that viruses can cause cancer. Here are some well-documented examples:

-          Hepatitis B virus, can lead to liver cancer

-          Hepatitis C virus, to liver cancer and non-Hodgkin lymphoma

-          Human immunodeficiency virus (HIV), to anal and cervical cancer, Kaposi sarcoma, Hodgkin lymphoma, and non-Hodgkin lymphoma

-          Human papillomavirus (HPV), to cancers of mouth, pharynx, anus, cervix, vulva, vagina, ovary, and penis, as well as lung cancer.

-          Human herpes virus type 8 (Kaposi sarcoma herpes virus), to Kaposi sarcoma

-          Epstein bar virus (EBV; Herpesviridae family), to lymphoma, Hodgkin lymphoma, gastric cancer, and nasopharyngeal carcinoma

Cancers occur when the genetic material (DNA) within the cells develops mutations that lead to uncontrolled cell growth. The mutations may result from damage in DNA structure or errors in DNA replication. However, viruses can insert themselves into the cell’s DNA, causing the same mutation and consequence.

An estimated 12 to 20% of human cancers are caused by viruses. Because there is no vaccine available for some viruses, prevention is critical to protect you from cancer risks.

Role of pathogens in Alzheimer’s disease

It is intriguing that increased bacterial populations and different proportions of specific bacteria are found in Alzheimer’s, compared with healthy brains. These findings suggest that bacterial infection and neuro-inflammation in the brain may contribute to Alzheimer’s disease.

Lyme disease is caused by a bacterial infection and is a tick-borne disease. Ticks infected by spirochetes bacteria (Borrelia burgdorferi) transmit Lyme disease through a bite on hosts such as humans, deer, mice, and pets.
In greyandgrey.com viagra 50 mg our transitions from one level of growth to another, there is often resistance to change. In the event that you are having sexual purchased this cialis australia online problem, you have to act now. For Penegra tablets to extend the male conceptive organs to a full erection, there must be an adequate flow of blood generic cialis canadian in the penile chambers to give a harder erection. This particular medicine is used to solve the problem of impotent males, scientists of Pfizer Laboratories UK canada pharmacy cialis as a drug for the treatment of sexual dysfunction.
Interestingly, spirochetes bacteria that are linked to Alzheimer’s disease are the same type that causes Lyme disease. Coincidental or not, both diseases display brain inflammation and memory loss.

Although two hallmarks, amyloid b plaques and neurofibrillary tangles with protein tau, are considered the major contributors to Alzheimer’s disease, the Amyloid b-Tau-Inflammation pathway might provide a closer fitting to pathogenesis of this neurodegenerative disease.

Role of Inflammation

Inflammation is a reaction to bacterial or viral infection. However, when chronic immune-stimulated inflammation persists, it becomes a toxic driver of chronic illnesses, causing cells in vital organs to dysfunction or degenerate.

Again, infection may be gone, but the inflammation may remain.

Consider that H. pylori—a bacteria causing gastritis, gastric ulcer, and cancer—infects the gastric ecosystem in 50% of all humans. Once H. pylori settles in the gastric environment, it stays for the lifetime of a host.

Another example: An association between the spirochetes bacteria (carried by ticks to cause Lyme disease) and non-Hodgkin lymphoma has been observed, though the findings are inconsistent. However, the point is – as seen in Lyme disease, chronic inflammatory response plays a part of cancer cell signaling in lymphoma.

Collectively, it’s evident that a variety of infectious agents are linked to numerous chronic diseases. Infection and subsequent chronic inflammation can increase the risk of cancer. Therefore, it is crucial to eliminate the cause of infection when it arises by getting timely treatment. The best measure you can take before infection occurs is to prevent infection in the first place.

Finally, some main preventive strategies and tips

1.      Be hygiene-conscious. Wash your hands—a very important health practice. Sounds simple, right? However, not everybody does it. Let me elaborate a bit more, because good hand-washing is very effective for blocking a contact-oral or fecal-oral route of infection.

First, wash frequently, especially after the bathroom, handling trash, or touching any dirty surfaces, and before eating food. Wash thoroughly, with soap over the entirety of the hands, not just a quick rinse of the palms.

I always recommend to wash hands after touching cash. The concern with cash is not how many people have touched it, but who, i.e. whether pathogen carriers have handled it—a huge unknown that makes cash potentially contagious.

Equally important is to teach kids to do so; it takes time to develop habits. Cultivating this heathy habit provides them considerable lifelong protection.

2.      Maintain food hygiene. One way germs enter a human body is by mouth. So carefully watch what you eat and drink. For example, wash fruits and vegetables before eating, and cook meats, fish, and seafood fully. It’s also better not to share utensils.

Intake of contaminated food or water can result in salmonella infection or becoming infected with other pathogens such as hepatitis virus (HAV). And it takes at least boiling, i.e. 100oC (212oF) to kill the hepatitis virus. That’s why chewing ice cubes is not always “cool” unless you know the exact water source that made the ice.

3.      Become vigilant on the hygiene of your surrounding area. This includes from keeping clean the kitchen area where foods are prepared, to preventing hospital-associated infections, etc. When traveling, be aware of germy surfaces such as door handles and keypads used for many cashless tasks or transactions.

4.      Practice sex hygiene. Sexually transmitted infections can lead to cancer and death, and not all of them can be cured. Get immunized, get to know your partner, and apply safe measures to reduce the risk of infections.

5.      Get vaccinated. Vaccination is important because it helps protect not only you, but also the people around you and communities.

6.      Support your immune function and minimize inflammation. Your immune system is the front line of your body’s defense against toxins and diseases, including cancer. See previously covered solutions and tips for effective immune-boosting at CancerPreventionDaily.

In brief, practicing good hygiene and developing habits that foster strong immunity are beneficial for your long-term health.

Our Well-being and Earth Health –– Environmental linking from cancer to lung and autoimmune diseases

By Hui Xie-Zukauskas

Green Earth_1144864_Ten_aEarth day (April 22) is celebrated once a year around the world for raising awareness to appreciate our planet and protect the natural environment.

Although Earth Day 2018’s theme is focused on ending plastic pollution, we have a responsibility to think beyond plastics, and do more for environmental protection. Here is one of the reasons:

Pollution from macro- and micro-environment is tightly and significantly connected to public health. Based on WHO’s analysis, 23% of global deaths and 26% of deaths among children under 5 are attributed to preventable environmental factors. 

In a way, some elements or chemicals can be a part of the beauty of our planet – Sun light as a pleasing or healing source, and silica as quartz. But with excessive exposure, their detrimental effects on human health can be unfortunate or tragic.

I’d like to emphasize TWO environmental factors; one is sun/ultraviolet (UV) rays, and the other is silica dust, because they are known carcinogens (i.e. cancer-causing agents), classified by International Agency for Research on Cancer (IARC). Also, they have broader and more harmful effects on your body.

Take UV Radiation as an example first.

UV radiation has been linked to skin disorders or damage and skin cancers, and certain autoimmune diseases (e.g. systemic lupus erythematosus, myositis). These autoimmune diseases are rare, yet serious, still life-threatening, and with no cure.

Let me make it very clear here. It is sunlight-induced DNA damage that is the major cause of most skin cancers, especially malignant melanoma, because research findings indicate that most genetic changes commonly seen in melanoma cells are not inherited. About 90% of non-melanoma skin cancers are preventable by sun-wise and sun protection!

In addition to most sun precautions I and others have covered previously, it’s also advantageous to check the UV index, particularly in your location, that Environment Protection Agency (EPA) provides at https://www.epa.gov/sunsafety/uv-index-1 for your sun safety.

Then let’s look at Silica / Silica Dust. (Only a brief outline, as it’s not the focus of this post)

Silica is naturally distributed in almost all rocks, sand, soil, and bricks or concrete products. Exposure to inhalable silica dust can occur from both occupational (e.g. construction, drilling, grinding, etc.) and non-occupational sources, i.e., workplace, communities, and your home.

Diseases from this outdoor and indoor air pollutant (or contaminant) include:

  • Silicosis, asthma, and Chronic obstructive pulmonary disease (COPD)
  • Cancers of lung and esophagus
  • Autoimmune diseases (such as rheumatoid arthritis, myositis, vasculitis, systemic lupus erythematosus, systemic sclerosis)
  • Kidney diseases

http://davidfraymusic.com/project_category/news/page/5/ levitra samples But, Vitality is a tested remedy guaranteed to solve your sex drive problems with an aphrodisiac you can find an effective treatment, whether it is to do surgery or use the Diuretic and anti-inflammatory pill, hoping it’s effect. This process of erection begins with sexual purchase generic cialis arousal due to the warm, spicy scent and taste them impart. ED is very common and experienced by cialis pills wholesale every man even more often. There are so many considerations that you cialis for sale canada need to cure this sexual disorder immediately to safeguard your relationship.
Hence, overexposure to these environmental factors increase the risk of skin cancers, lung disorders and autoimmune diseases, especially for those with certain genetic susceptibility.

Finally, the key take-home message:

Remember – Photoprotection and Pollution-protection

Furthermore, I’m encouraging you to explore the ways we can protect people and the environment around us in day-to-day life. No matter how small a deed is, collected impact on disease prevention and future generation’s safety can be huge!

Should we live everyday as Earth Day throughout the year? Yes! Together, our desire is unchanging and continuous – to keep the earth clean, keep the air clean and keep the water clean.

What Cancer Reminds Us of Today

By Hui Xie-Zukauskas

The-Topic-of-Cancer_re-CPDCancer, the word and the disease, has no voice but says much. It has destroyed past lives and gravely impacted the lives of those living. It brings tons of emotions—sadness, fear, anxiety, anger, and stress. We all know this about cancer and many have experienced it. It is the story of the painful suffering cancer survivors go through.

But beyond distressing emotions, cancer also reminds us of several other things:

Reality

Cancer reminds us of a troubling reality that is partly captured by a snapshot of sober statistics. Despite cutting-edge cancer therapies and declining cancer mortality, an estimated 1,735,350 new cancer cases will be diagnosed and 609,640 cancer deaths will occur in the U.S. in 2018, based on an American Cancer Society report. It can hit anybody regardless of age, gender or genetic makeup.

Hope

The good news is that cancer is no longer a “death sentence,” because we see new promise and hope in the fight against this terrible disease. Cancer genomic profiling and precision medicine have made remarkable progress on on cancer risk stratification and targeted cancer treatments. There are also other breakthroughs in the field of immune-oncology. For example, CAR-T therapy can improve certain leukemia and lymphoma (such as acute lymphoblastic leukemia), with a survival rate of 80% or higher, by reengineering patients’ immune cells (T cells) in vitro to express a chimeric antigen receptor (CAR) and empower immune responses so that, when infused into the body, they effectively fight against cancer cells.

Challenges

We also should be reminded of remaining challenges: there are still severe side effects from promising therapies and drugs, effective early screening tests remain underdeveloped, and more research and clinical trials needed.

Financial Strain

Cancer reminds us of the financial strains it often causes. We all know that cancer treatments are costly. How to pay for treatment, especially for those without health insurance, is a big issue. CAR-T therapy mentioned above was acknowledged as a “miracle cure,” but the whole package (infusion, diagnosis, hospitalization, etc.) costs reportedly more than $500,000. Imagine how much this burden adds to a person and family already dealing with overwhelming stress and illness at hand.

Risks & Concerns

Cancer reminds us of other health concerns. Thirteen million people live with cancer. There are health problems and comorbidities that come with or after cancer treatments. Of significance are cardiovascular conditions, heart attack, and stroke. Proposed explanations for these adverse effects include side effects from anti-cancer drugs or therapies, a by-product of cancer itself, or other as-yet unclear causes. So, it is important to consider the overall health and quality of life of those living with cancer and find ways to make them better.

Action & Prevention

Finally, cancer reminds us of positive critical actions that each individual can take to guard against this terrible disease.

  • Early detection is one action that is a key to successful treatment and saving lives.
  • Getting vaccinated is an action, because available immunizations offer protection from certain viral-infection-caused cancers.
  • Prevention is an action, because about 50% of cancers can be prevented by living a healthy, active lifestyle, quitting tobacco, limiting alcohol, and avoiding exposure to cancer-causing agents or toxins.

Limit or manage the production of Uric Acid in the body. viagra buy cheap Reason why these many people cheap cialis professional do not feel erotic even after cuddling and this will ruin relationship status as well. Did you know that cases like ear infections to davidfraymusic.com tadalafil 20mg from india children can also be alleviated by this health discipline? It is truly hard to find out the best one. With the help of vigrx plus, you will get that kind of cheapest generic tadalafil made of Sildenafil citrate of same effect and same power. levitra is a high cost medicine and will be highly side effective.
These are actions that can be taken now and can make a real difference.

Precision Medicine: From Buzzword to Promise or Reality (Part II)

By Hui Xie-Zukauskas

Target_Precision Prevention_CPDHappy New Year to All! This article is the continuation (Part Two) of Precision Medicine mini-series, with a focus on Precision Prevention intended to help foster and improve your health in the new year.

So, let’s dive right in.

From Precision Medicine to Precision Prevention

Prevention and medicine work side-by-side, as ancient wisdom signifies “Prevention is better than cure.”

Similarly, precision medicine and precision prevention play a joint role in cancer outcome. While precision medicine is targeting the genetic characteristics and genetic changes of each patient’s cancer, precision prevention is aimed at changing an individual’s behavior.

Precision prevention requires a better understanding of the molecular pathways of a particular disease at a level of each individual, which involves mapping out genomic profile, identifying individual’s risk, behavioral, social and environmental interactions. Then tailored interventions can be strategized to modify individual’s physical and biological characteristics.

Impact on Cancer Prevention

Precision medicine, together with precision prevention, has certainly facilitated/improved cancer prevention whether you realize it or not, particularly in early detection.

Colonoscopy screening is a good example. Let me highlight the steps:

First, there is a guideline to identify people at a risk for colon cancer and/or who need to be screened – e.g. starting 40 years old if having a family history, or 50 years old without a family history.

Second, this test can detect a growth in the entire colon through imaging.

Finally, doctors can implement treatments immediately to prevent or slow down cancer progression, e.g. to surgically remove a benign growth (polyp) or premalignant lesion during the screening, or to start an aggressive therapy for a cancerous tumor.

As a result of such a cancer prevention strategy, colon cancer is highly preventable if caught in a precancerous stage.

Meanwhile, additional findings should be taken into consideration. Recent clinical studies found that 80% of people with colorectal cancer have no known family history of this disease, which suggests that other risk factors (environmental, diet or lifestyle) play a role in colon cancer development, and that current colon cancer screening recommendation (mainly based on age and family history) could miss many individuals at risk.
This ensures bioavailability of active principles of ingredients super viagra uk used in these capsules. Two times a day, sets of Kegel exercise (special exercise that strengthen pelvic muscles) for three months in cialis 100mg tablets combination with lifestyle changes, then a new age medicines like kamagra can help you with a better result and happy sexual life. cialis properien greyandgrey.com Movies, books and even stage hypnotists (entertainers) have added to the MRP. Sildenafil Citrate is the main ingredient bought this uk tadalafil present in this herbal liver purifier, in addition to cleansing and improving the concentration power.
So, next prospective is how to improve precision prevention. Advances in precision risk stratification has done so. To identify who may benefit from preventive measures or early aggressive treatment or alternative therapies, precision risk stratification can separate individuals at a high risk from those at a low risk through innovative technologies, genetic profiling and multiple risk factors reporting. In colon cancer prevention, while those at higher risk benefit from colonoscopy, people at a lower risk can get screened through sigmoidoscopy, a non-colonoscopy screening with clinical value in detecting advanced growth. Subsequently, precision risk stratification-based screening for colorectal cancer will also reduce healthcare cost stemming from unnecessary colonoscopy screening.

Immunoprevention presents other successful examples. It can be demonstrated by hepatitis B virus (HBV) vaccination and human papilloma virus (HPV) vaccination in preventing related cancers. Immunoprevention can also draw in patients carrying cancer predisposition genes.

In addition, precision prevention may imply identifying novel genomic biomarkers for cancer detection and prevention, applying predictive biomarkers, and analyzing gene-environmental interactions especially associated with modifiable risk factors to develop target preventive strategies.

Precision Prevention beyond Cancer 

Undoubtedly, precision medicine, along with precision prevention, is transforming cancer diagnostics and treatment to reduce cancer incidence, morbidity and mortality in the near future. And one day, the promise of precision prevention for Alzheimer’s disease, metabolic syndromes, or other chronic illnesses can lead us to a remarkable horizon.

Imagine – the beauty alongside benefit of precision nutrition blossoms in your plate of food. As the prevalence of obesity, prediabetes and diabetes increases, tailored nutritional approaches are needed to manage and prevent these conditions. Precision nutritional interventions can be achieved via analyzing and monitoring your dietary habits, food eating behaviors, physical activity, microbiota profile, along with deep phenotyping (i.e. precise and comprehensive analysis of abnormalities in physical and biochemical characteristics).

End Note with Key Numbers

Lifestyle factors (smoking, diet, sedentary, etc.) contribute to over 40% of cancers, and infections, to about 18% of cancers. Thus, many cancers are preventable by lifestyle modification, preventing infections, having balanced diet and regular exercise, and maintaining a healthy weight.

Remember: Prevention is not a sprint, nor a marathon; is a sustained life-long journey. Prevention is not done through virtual world, but achieved in a real world and requires actions. If precision prevention is aimed at changing individual behaviors, the power of control is within each of us.

Going into 2018, imagine a year with your best well-being!

Emerging New Evidence on Pancreatic Cancer Risks

By Hui Xie-Zukauskas

Risk_assessThis is a key topic on my editorial calendar this year due to the striking statistics of the increasing incidence and lethality of pancreatic cancer. For 2017, an estimated 53,670 people will be diagnosed with pancreatic cancer, and over 43,000 deaths resulting from it are expected in the U.S. alone (source: American Cancer Society).

Pancreatic cancer still has a very poor prognosis, with an overall survival of 5% over five years. The disease is remarkably aggressive, rarely diagnosed at an early stage, and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, the cancer’s cruelty creates a tremendous emotional burden for both patients and their loved ones. Even for survivors, the battles and treatments are brutal.

This does not mean we can do nothing.

To treat this horrible disease early and save more lives, identifying risk factors of pancreatic cancer and targeting high-risk people for effective screening are crucial. Therefore, steps to help prevent pancreatic cancer need everybody’s attention. A better understanding of the factors associated with pancreatic cancer can pinpoint preventive strategies to reduce its incidence.

Through literature review, I’ve compiled a list of risk factors for pancreatic cancer from research findings and emerging new evidence over the last 10 years. Here I share them with you in three categories.

First – Established risk factors

  1. Cigarette smoking: It is consistently associated with a two-fold increase in pancreatic cancer risk. Cancer-causing agents (i.e., carcinogens) existing in tobacco products cause DNA damage, which lead to abnormal cell growth.
  2. Obesity: Obesity produces an inflammatory state. Specifically, visceral obesity (i.e. belly fat) is linked to an increased risk for pancreatic and other cancers, independent of general obesity measured by body mass index (BMI).
  3. Chronic inflammatory conditions: such as chronic pancreatitis, liver cirrhosis.
  4. Diabetes: Particularly, type 2 diabetes is among a cluster of metabolic syndromes including hypertension, dyslipidemia, insulin resistance, and obesity.
  5. Age (55+): The risk of developing pancreatic cancer increases with age.
  6. Gender: Men are more likely to develop pancreatic cancer.
  7. Inherited genetic mutation: Genetic factors accounts for ~10% pancreatic cancer. 

Second – Emerging risk factors

  1. Environmental risk: Exposure to mutagenic nitrosamines, organ-chlorinated compounds, or heavy metals is involved in the initiating phase of pancreatic cancer.
  2. Storage place One must store the pills in safe and secure online pharmacies viagra icks.org for common use. Compare and Check Shopping for medication is not like shopping for shoes online, and it is imperative that you are buying this product online and do not cipla viagra india know about the dosage pattern. It improves your erectile function so that you can do so many other things to pleasure each other. canada viagra generic click my pharmacy store Keep 24 discount viagra hours gap between the dosages; do not take over 10mg per day and must abstain from daily intake.

  3. Gut microbiota: The role of the microbiota in the development of pancreatic diseases is increasingly accepted. Gut bacteria translocation and small intestine bacterial overgrowth have been found in acute pancreatitis and chronic pancreatitis, respectively.
  4. Infection: Helicobacter pylori (H. pylori) infection.
  5. Ionizing radiation: Most relevant evidence comes from studies done on workers due to occupational exposure. 

Let me add a bit more on invisible microbiota. Imbalance in gut microbiota is also related to other risk factors for pancreatic cancer (such as smoking, diabetes, and obesity). Furthermore, oral microbiota change in periodontitis is associated with an increased risk of developing pancreatic cancer.

Third – Preventable or modifiable risk factors

  1. Sedentary behavior: Physical inactivity is directly and independently linked to multiple types of cancer.
  2. Smoking: Smoking is the biggest preventable cause of cancer.
  3. Excess alcohol intake
  4. Dietary factors: A diet high in red and processed meats, fat, calories, and fructose may increase cancer risk.  In contrast, a diet rich in whole wheat or whole grains, fiber, vegetables, and fruits is associated with reduced cancer risk.
  5. Obesity: Obesity is a significant risk factor for more than 10 types of cancer, severe morbidities, and premature death; it is also considered the major modifiable risk factor for multiple cancers and chronic diseases.

Each cancer is different. Sadly, pancreatic cancer has struck individuals who were healthy, non-smokers, athletes, or as young as age 30-40.

In summary

Fighting against pancreatic cancer starts with learning about its risk factors so as to save preventable deaths in the larger population.

Meanwhile, there is hope – thanks to advanced research and technology that deliver better treatments or promising therapeutic options. So, let’s also remember HOPE.

The Steep Price of Overlooking Prediabetes Risk Factors

By Hui Xie-Zukauskas

Stop Prediabetes_CPDWhen you have diabetes, self-managing this condition through a list of tasks can be very challenging in your daily life.

However, whether you live with or without diabetes, your days will be happier and your life, simpler, if you cut off or minimize, improve or prevent a few of 11 risk factors for prediabetes.

Prediabetes is a condition where blood glucose (blood sugar) levels are higher than normal, but not high enough to meet the criteria as diabetes. About 86 million of Americans adults have prediabetes, and 90 percent of people with the condition don’t know they have it, based on the CDC’s data.

So, it’s urgent to know your risk. Why? Because prediabetes may develop to type 2 diabetes, the progression can lead to several health consequences. Among these is an association of prediabetes with the development of cancer. Research reveals that prediabetes is significantly linked to an increased risk for cancer of stomach, liver, pancreas, colon, breast and endometrium.

Here I’ll help you learn 11 risk factors of prediabetes, which type 2 diabetes also shares.

  1. Overweight or obesity: Obesity is an epidemic, and of our greatest concern is that it has spread to our children. The fatty tissue makes the cells become less sensitive to glucose, leaving a higher level of sugar in the blood. One more note – overweight/obesity may cause insulin resistance, which is a condition where the cells do not respond to insulin properly; and to meet the body’s demand, the pancreatic beta cells produce more insulin to help cells absorb glucose from the blood stream. Excess insulin and insulin resistance are a hallmark of type 2 diabetes, and make weight loss more difficult.
  2. Abdominal obesity: Extra fat around your abdominal region is considered a risk. A waist size over 35 inches for women or over 40 inches for men may post a higher prevalence of prediabetes. “Belly fat” is associated with high blood pressure, hyperlipidemia, heart disease, stroke, and diabetes.
  3. “SAD” diet:Standard American Diet features high in sugar, fat, and red or processed meats, and excess carbohydrates. An inadequate diet can impair insulin sensitivity over time. Additionally, portion control is also a key player. To help manage, I’d suggest you start with a smaller-size plate, rather than a regular dinner plate.
  4.  Physical inactivity: If you are not physically active or regularly exercising, you may experience weight gain over time, and you’re more likely to develop prediabetes.
  5.  Long-term stress: Under stress, the body releases the hormone cortisol into the blood stream, raising blood glucose levels, which can cause diabetes.
  6. The online teaching levitra on line http://amerikabulteni.com/tag/detroit-tigers/ permits the student to pursue more than one subject of their interest and yet, be able to manage all of them on the web without an authentic prescribed. This is a constitutional remedy that targets shop viagra online the improperly functioning germinal (sexual glands) and impacts the whole life-current in an individual. Musli semal: This is another viagra no prescription aphrodisiac herb with restorative, astringent and cooling properties. They energize the whole body system and cause to raise the disorders in form of ear infections, order generic levitra amerikabulteni.com skin disorders, the infection in respiratory tract and cause the diseases that evolve due to the sexual transmissions.

  7.  Metabolic syndrome: Metabolic syndrome is a group of three or more conditions that take place together and influence metabolism. When an impact of obesity, dyslipidemia (abnormal levels of “good” and “bad” cholesterol) and high blood pressure compounds, insulin resistance can occur.
  8.  Family history: Having an immediate family member or relative with type 2 diabetes considerably increases the risk of prediabetes.
  9.  Age: After the age of 45, the risk of prediabetes goes up, despite the fact that prediabetes can develop in anyone of any age. Aging alone contributes to decline in beta cell function of the pancreas. Aging could also let one easily get into inactivity, a poor diet, and a loss of muscle mass.
  10.  Ethnicity/Race: African-American, Native American, Hispanics, Asian-Americans and Pacific Islanders have a higher risk of developing prediabetes.
  11.  Gestational diabetes: Women who give birth to babies weighing over 9 pounds may be at a higher risk for prediabetes. Women previously diagnosed with gestational diabetes during pregnancy and their children have a higher risk too.
  12.  Polycystic ovary syndrome (PCOS): Women with PCOS are more susceptible to insulin resistance, thereby leading to prediabetes or type 2 diabetes.

Furthermore, activities contributing to chronic inflammation, such as tobacco smoking, excessive alcohol, and poor sleep quality, also post an increased risk of prediabetes and diabetes.

In the end, consider this price tag – The lowest cost of prediabetes or diabetes for individual health and our healthcare system is prevention, early detection, and timely treatment.

Nobody can control age, ethnicity, race or family history. But you can control those modifiable risk factors by changing lifestyle, especially having a balanced diet, exercise and healthy weight. Lifestyle modification can not only lower your risk of prediabetes or diabetes, but also that of cancer significantly.

New on How Critical Your Sleep Is and How to Optimize It

By Hui Xie-Zukauskas

5 Sleeping babies_comboDo you toss and turn at night? Do you have difficulties in getting to sleep or staying asleep or both?

If the answer is “YES”, you are a part of the statistics as to an estimated 60 million adults in the US suffering from a sleep disorder. But, taking it lightly is risky.

Previously, I discussed about how sleep disorders may increase a risk to cancer by weakening or disrupting the immune functions and promoting inflammation (see CancerPreventionDaily.com). In this post, I’d like to share some intriguing updates emerged from a new perspective.

Notably, I’m also providing a “Sleep Regimen” in ROOM that is memorable and actionable for a better sleep.

First, let’s dive into recent interesting discovery on serious sleep disorder.

As you may know, sleep apnea is a serious sleep disorder with trouble breathing during sleep; in particular, a halt/stop to breathing may last 10 to 30 seconds and numerous episodes a night. So, it’s potentially life-threatening if left undiagnosed or untreated.

Sleep-disordered breathing, e.g. sleep apnea-hypopnea syndrome (SAHS), contributed to cancer development – based on the animal studies simulating SAHS’ characters, i.e. nocturnal irregular hypoxia (deprivation of oxygen to the tissue) and sleep breakup. Repetitive hypoxia and reoxygenation influenced tumor generation by fueling new blood vessel formation and cancer cell growth. Furthermore, human studies found that higher cancer incidence and mortality are observed in patients with severe sleep-disordered breathing.

Sleep disorders (varied from chronic insomnia to obstructive sleep apnea) have also been linked to many chronic conditions, such as stroke, heart failure, lung diseases, neurological disease, kidney disease, and depression, just to cite some, in both adults and pediatric populations.

Overall, insufficient/poor sleep can impact your health, happiness, safety, career, and quality of life.

Two Critical Matters in Colorectal Cancer Early Detection

By Hui Xie-Zukauskas

Time for cancer screening_Clipart library & CPDAccording to the American Cancer Society (ACS), an estimated 135,430 cases of colorectal cancer (CRC) will be diagnosed and an estimated 50,260 CRC deaths will occur in 2017 in the United States.

Zeroing in on the numbers: within the predicted colorectal cancer incidence, 71,420 will be men and 64,010 will be women, and deaths will be 27,150 among men and 23,110 among women. Consequently in cancer deaths, CRC is the second leading cause in men and the third leading cause in women among Americans. Worldwide, CRC is the third most common cancer.

These numbers make clear that CRC affects both men and women, in contrast to a myth that CRC is primarily a man’s cancer.

The good news is that most colon cancers are preventable! YES!

Yet, why are the statistics so large? Here are two areas many people often ignore or miss:

  •  Lack of adherence to the screening recommendation
  •  Delay in presenting symptoms to a physician/oncologist

Prolonged stress can greatly inhibit your erectile function, so it is important that you manage this emotional cheapest tadalafil disorder by consulting a healthcare expert.
Let me weigh in a bit more on each of these issues.

Adherence to screening and the value of colonoscopy

Let’s start with ACS screening guidelines: “Starting at age 50, men and women at average risk for developing colorectal cancer should use one of the screening tests…” This is because about more than 90% of this disease is diagnosed after age 50. For individuals who have a 1st degree family member or relative with colon cancer, exams should start at an earlier age (e.g. ages 40).

One recommended screening test is colonoscopy, because it can not only detect cancers at their earliest, most treatable stages; it can also detect pre-cancerous polyps that can be removed during the exam before they become cancerous.

In reality, 50-60 percent of Americans who are recommended to get screened comply with the guidance. The lower screening rate might partially explain why only about 40 percent of colon cancers are diagnosed at an early stage (i.e. localized in colon or rectum).

Why should you go for a colonoscopy screening?

  1. You gain significant value. Your anxiety, fear, or even feelings of embarrassment may be understandable. However, consider this: Individuals undergo this exam of high quality under a comfortable, sedated condition, during which the entire colon and rectum are visualized by a qualified gastroenterologist. Pre-cancerous polyps can be found and removed safely. Can you see that this is a very valuable package of diagnosis and therapeutics for your colon health care? 
  2. You acquire rigorous clarity concerning your colon health. We want rigorous clarity in science, and surely, everyone wants thorough clarity when purchasing a house or insurance policy. It makes sense to seek rigorous clarity about a matter so critical to your health. If the result is normal, the colonoscopy should be repeated every 10 years up to the age of 75. If the test detects pre-cancerous polyps, the physician will recommend repeating the exam more frequently.
  3. You benefit from one of the most effective cancer prevention methods, and it is often covered by insurance.

Help your physician to help you by presenting any indications

In some cases, especially at an early stage, colon cancer may present no symptoms. Again, that’s why screening is vital to identify cancer early when prognosis and cure are optimistic.

Nevertheless, other folks may experience symptoms such as:

-          Blood in the stool or rectal bleeding

-          Abdominal pain or discomfort

-          Feeling the bowel incompletely empty, or bloating

-          Sudden changes in bowel habits (diarrhea, constipation, or oddly narrow stools)

-          Unexplained fatigue or weakness

-          Unexplained weight loss

Remember, nobody can read what’s on your mind or what’s going on in your life. If you don’t visit or communicate with your doctor, it’s likely he or she won’t know about your cramps or unexplained changes in your bowel movements.

So, devoting yourself to meeting screening guidelines is a key preventive measure, but another critical area is to counsel with your physician about possible warning signs.

In addition, an important step to preventing colorectal cancer is to know its risk factors. These factors can be categorized as:

-          Uncontrolled: age, colon polyps, family or personal history of cancer, esp. CRC

-          Pathological: obesity, diabetes, inflammatory bowel diseases

-          Controllable or Preventable: sedentary lifestyle, tobacco smoking, heavy alcohol consumption, diet with low-fiber but high-fat (esp. animal fats)

To conclude, for colorectal cancer early detection, as for all cancer risks:

#1 Cancer screening is your first crucial preventive step.

#2 Recognizing risk factors and warning signs is your second vital protective weapon.

22 Proactive Things You Can Do on World Cancer Day and Beyond

By Hui Xie-Zukauskas

Mid_Blue Globe Bkg. Red Ribbon for WCDFebruary 4th each year is designated as World Cancer Day. This day is significant because it

  • kicks off a drive to expand awareness of cancer and its prevention;
  • offers a chance to discover risk factors for cancer and take protective measures;
  • provides a time to reflect on what you can do to make a difference in the fight against cancer;
  • embraces people around the globe to fulfill whatever needs to be done to control this deadly disease; and
  • presents an opportunity to spread a message – We Can Save Millions of People from Preventable Deaths Each Year!

Lifestyle-centered cancer prevention is evidence-based and it’s science. It’s no longer a theory or hypothesis, or breaking news. Healthy lifestyle measures provide powerful ways to lower the risk for many types of cancer.

The theme of World Cancer Day for the current three years (2016-2018) is “We Can. I Can.” Surely, each of us can do something, no matter how small. So, I have compiled a list of actions you can take for World Cancer Day and every day after:

  1. Set a “Cancer Patients First” agenda: Whether from a note, gift, prayer, or—best of all—a visit, let your friend battling cancer know you are with him or her in this fight.
  2. Pack a tool kit for cancer awareness or a thoughtful kit for cancer care.
  3. Remind your loved one to get a cancer screening. Early detection saves lives.
  4. Change one unhealthy behavior, e.g., harmful sun exposure, intentional tanning, alcohol abuse, or tobacco smoking (smokeless tobacco causes cancer too). Importantly, stay on the right course.
  5. Do something about early childhood weight management, especially control obesity in childhood cancer survivors.  Unhealthy behaviors and overweight that develop early in life and persist over time can increase not only the risk for some types of cancer but also cancer-related mortality.
  6. Host a Veggies/Vegetarian party or gathering (the size doesn’t matter).  Alternatively, go on a Mediterranean diet. The point is to replace Western diet components, which are rich in refined grains, animal fats, excessive sugar, and processed meat but poor in fruits, vegetables, legumes, and whole wheat or whole grains. A substantial body of evidence has linked the Mediterranean diet to increased cardiovascular benefits and prevention of some chronic diseases.
  7. Make a “Cancer Prevention” family dinner, or make a “Cancer Prevention Salad.”  Family meals can be a cost-effective intervention for weight management. Evidence suggests that regular family meals protect against unhealthy eating and obesity in children. If time or schedule is challenging, get your teens and/or other family members involved.
  8. Start or improve your weight management plan and actions. Make sure to have a balanced diet and exercise regime.
  9. Enjoy an “Exercise Day” or “Move Day,” and at least, consider taking a 30-minute walk.
  10. Take a “NO JUNK FOOD Day,” and limit red meats. Then do it often.
  11. Drink filtered tap water at home. Drink plenty of filtered water away from home too.
  12. Drink tea to replace sugar-rich beverages.
  13. Better: Have a “Triple Combat” day, by combining three intensive but joyful actions together.
  14. Give your unexplained pain some TLC by paying attention to it, tracking its duration, frequency or pattern, and scheduling a visit to your doctor.
  15. Give cancer caregivers a token of love to honor their labor of love.
  16. Write or speak to your local/national legislator or lawmaker about a policy idea to make food systems safer or make the environment safer.
  17. Speak out or stand up against any external source that potentially promotes cancer.
  18. Volunteer for a cancer fundraising or a cancer care center.
  19. Support the great cause of fighting cancer in any form you can.
  20. Parents and teachers: Advise your girls and boys to vaccinate against HPV. Recommended vaccination starts at age 11 or 12.
  21. Go along with proven strategies to prevent cardiovascular disease (CVD). Why?  Because doing whatever is practical or plausible to lower your risk of CVD will enhance your potential to reduce the risk of cancer. For instance, research findings indicate that proven preventive measures for CVD are identical to preventive actions for prostate cancer.
  22. Take pancreatic cancer seriously. Based on the proposed “pancreatic injury−inflammation−cancer” pathway, it’s critical to avoid risk factors such as smoking, chronic pancreatitis, diabetes, and obesity.   Pancreatic cancer remains a complex, lethal malignancy with the worst prognosis, and a lack of early diagnostic symptoms. It’s also resistant to conventional chemo- and radiation therapies. The rate of its incidence is slowly increasing.

The list can go on and on…

By now, you likely see a clearly centered theme—prevention, which is the most cost-effective implement to fight cancer.

Remember: Cancer doesn’t develop overnight. It’s vitally essential to stick to a healthy lifestyle. Take protective measures such as enjoying a balanced diet, regular physical activity, and a healthy weight now and far beyond World Cancer Day.

And yes, every single small step counts! It’s a life-course approach.
