Why eating yogurt may help lessen the risk of breast cancer

In continuation of my update on yogurt

One of the causes of breast cancer may be inflammation triggered by harmful bacteria say, researchers.

Scientists say their idea- as yet unproven—is supported by the available evidence, which is that bacterial induced inflammation is linked to cancer.

The paper in the journal Medical Hypotheses is by Lancaster University medical student Auday Marwaha, Professor Jim Morris from the University Hospitals of Morecambe Bay NHS Trust and Dr. Rachael Rigby from Lancaster University's Faculty of Health and Medicine.

The researchers say that: "There is a simple, inexpensive potential preventive remedy; which is for women to consume natural yoghurt on a daily basis."

Yoghurt contains beneficial lactose fermenting bacteria commonly found in milk, similar to the bacteria—or microflora- found in the breasts of mothers who have breastfed.

Dr. Rigby said: "We now know that breast milk is not sterile and that lactation alters the microflora of the breast.

"Lactose fermenting bacteria are commonly found in milk and are likely to occupy the breast ducts of women during lactation and for an unknown period after lactation."

Their suggestion is that this lactose fermenting bacteria in the breast is protective because each year of breast feeding reduces the risk of breast cancer by 4.3%.

Several other studies have shown that the consumption of yoghurt is associated with a reduction in the risk of breast cancer, which the researchers suggest may be due to the displacement of harmful bacteria by beneficial bacteria.

There are approximately 10 billion bacterial cells in the human body and while most are harmless, some bacteria create toxins that trigger inflammation in the body.

Chronic inflammation destroys the harmful germs but it also damages the body. One of the most common inflammatory conditions is gum disease or periodontitis which has already been linked to oral, oesophageal, colonic, pancreatic, prostatic and breast cancer.

The researchers conclude that: "The stem cells which divide to replenish the lining of the breast ducts are influenced by the microflora, and certain components of the microflora have been shown in other organs, such as the colon and stomach, to increase the risk of cancer development.

"Therefore a similar scenario is likely to be occurring in the breast, whereby resident microflora impact on stem cell division and influence cancer risk."

FDA Approves Adhansia XR (methylphenidate hydrochloride) Extended-Release Capsules for the Treatment of ADHD

In continuation of my update on methylphenidate

Adlon Therapeutics L.P., a subsidiary of Purdue Pharma L.P., announced that the U.S. Food and Drug Administration (FDA) approved Adhansia XR (methylphenidate hydrochloride) extended-release capsules CII, a central nervous system (CNS) stimulant, for the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in patients six years and older. In a simulated Adult Workplace Environment (AWE) study, Adhansia XR demonstrated statistically significant improvement over placebo at 1, 2, 5, 8, 11, and 16 hours post-dose, but not at hour 14 post-dose.1

“Methylphenidate medications, when used as prescribed and in conjunction with behavioral therapy and lifestyle interventions, are one of the preferred first-line treatments for certain patients diagnosed with ADHD,” said Marcelo Bigal, MD, PhD, chief medical officer, Purdue Pharma, and general manager, Adlon Therapeutics. “We are pleased to receive FDA approval for Adhansia XR, a new option for appropriate patients with ADHD who may benefit from a treatment with efficacy demonstrated at one hour and 16 hours post-dose in adults, and we look forward to making it available later this year.”

The Full Prescribing Information for Adhansia XR contains a boxed warning for abuse and dependence. CNS stimulants, including Adhansia XR, other methylphenidate-containing products, and amphetamines have a high potential for abuse and dependence. Healthcare professionals should assess the risk of abuse prior to prescribing Adhansia XR and monitor for signs of abuse and dependence while patients are on therapy.

“Some of my patients with ADHD, especially those who are balancing school or work and participating in social or civic activities, require the ability to sustain attention throughout the day,” said Andrew J. Cutler, MD, chief medical officer, Meridien Research, and an investigator on Adhansia XR clinical studies. “The approval of Adhansia XR offers a methylphenidate treatment option with a longer duration of efficacy, which may be appropriate for these patients.”

Adhansia XR is not appropriate for all patients, and healthcare professionals should work with their patients to determine the most appropriate treatment option. Additionally, Adhansia XR is contraindicated in patients with a known hypersensitivity to methylphenidate or product components, as well as patients receiving concurrent treatment with a monoamine oxidase inhibitor (MAOI) or who have used an MAOI within the preceding 14 days.

The Full Prescribing Information for Adhansia XR, including Boxed Warning, is available at this link. Additionally, please see Important Safety Information for Adhansia XR below, including the Boxed Warning, Contraindications, Warnings and Precautions including the potential for abuse and dependence, serious cardiovascular events, blood pressure and heart rate increases, psychiatric adverse reactions, priapism, peripheral vasculopathy, long-term suppression of growth, allergic-type reactions, and Adverse Reactions.

“ADHD affects a significant number of adolescents and adults and, when not optimally treated, can negatively impact various aspects of their lives. A subset of these patients experience impairment throughout the day. While Adhansia XR is not appropriate for all patients, a methylphenidate medication available in a single daily dose that, in adults, demonstrated efficacy at one hour and at 16 hours post-dose, has the potential to address the needs of certain individuals with ADHD,” said Craig Landau, MD, president and CEO, Purdue Pharma. “We are committed to providing information on safe prescribing practices for this medication and initiatives to support the responsible use, storage, and disposal of all medications in this class."

The FDA approval of Adhansia XR was based on four clinical studies evaluating the efficacy and safety of Adhansia XR in patients who met DSM-5 criteria for ADHD. Eight hundred and eighty-three (883) patients were exposed to Adhansia XR during 1- to 4-week long, controlled treatment periods (434 adult patients and 449 pediatric patients [156 (6 to 12 years); 293 (12 to 17 years)] from two clinical studies in adults, one analog classroom trial over a 13-hour study day in pediatric patients ages 6 to 12 years, and one safety and efficacy study in pediatric patients ages 12 to 17 years). The safety data for adult patients are based on two randomized, double-blind, placebo-controlled studies in doses of 25 mg to 100 mg per day. The safety data for pediatric patients (6 to 17 years) are based on randomized, double-blind, placebo-controlled studies in doses of 25 mg to 85 mg per day.

A double-blind, randomized, placebo-controlled crossover AWE study evaluated Adhansia XR in adult patients with ADHD. Efficacy assessments were conducted at pre-dose and 1, 2, 5, 8, 11, 14, and 16 hours post-dose. The primary endpoint was the mean Permanent Measure of Performance Total scores (PERMP-T), averaged across all time points compared to placebo. PERMP-T, an objective, validated skill-adjusted math test, is the combined score obtained by adding PERMP-A (number of math problems attempted) and PERMP-C (number of math problems answered correctly).

While receiving Adhansia XR, adults achieved statistically significant improvement over placebo, achieving greater mean PERMP-T scores averaged across all time points on the AWE days (post-dose score of 281.3 vs. 254.5; difference of 26.80, 95% CI [15.19, 38.41]). The secondary efficacy endpoints were onset and duration of clinical effect, as assessed by the treatment difference in PERMP-T scores at post-dose time points. Adhansia XR demonstrated statistically significant improvement over placebo at 1, 2, 5, 8, 11, and 16 hours post-dose, but not at hour 14 post-dose.

In this study, 10% of Adhansia XR-treated patients discontinued due to adverse reactions compared to 0% of placebo-treated patients. The following adverse reactions led to discontinuation at a frequency of 2% of Adhansia XR-treated patients: nausea, bronchitis, viral gastroenteritis, viral infection, increased blood pressure, and hypomania.

Sudden death, stroke and myocardial infarction have occurred in patients treated with CNS stimulants at recommended doses. Additional information about serious cardiovascular risks can be found in the Important Safety Information section below.

Adhansia XR will be available in six capsule strengths (25, 35, 45, 55, 70, and 85 mg), allowing for flexible dosing. The recommended starting dose of Adhansia XR for patients six years or older is 25 mg once daily. Healthcare professionals should titrate the dose in increments of 10 mg to 15 mg at intervals of no less than five days. Adhansia XR should be taken orally once daily in the morning, with or without food. Capsules may be taken whole or, for patients who have difficulty swallowing, capsules may be opened and the entire contents sprinkled onto a tablespoon of applesauce or yogurt. The entire mixture should be consumed without crushing or chewing, immediately or within 10 minutes. If the mixture is not consumed within 10 minutes after mixing, it should be discarded and not stored. The dose of a single capsule should not be divided and patients should not take anything less than one capsule per day. In the event of a missed dose, patients should not take their medication later in the day.

Prior to initiating treatment with Adhansia XR, healthcare professionals should also assess for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam). Healthcare professionals should assess the risk of abuse prior to prescribing Adhansia XR and monitor for signs of abuse and dependence while patients are on therapy. After prescribing and while patients are on therapy, healthcare professionals should maintain careful prescription records, educate patients and their families about abuse and proper storage and disposal of CNS stimulants, and periodically re-evaluate the need for Adhansia XR use.

Dosages above 85 mg daily in adults and 70 mg and above daily in pediatric patients are associated with disproportionate increases in the incidence of certain adverse reactions. If paradoxical aggravation of symptoms or other adverse reactions occur, healthcare professionals should reduce the dosage, or, if necessary, discontinue treatment with Adhansia XR. Treatment with Adhansia XR should also be periodically discontinued to assess the patient's condition. If improvement is not observed in a patient after appropriate dosage adjustment over a one-month period, healthcare providers should discontinue treatment with Adhansia XR.1 Healthcare professionals should refer to the Full Prescribing Information for additional Dosage and Administration information.

Prescription stimulants, which include methylphenidate, the active ingredient in Adhansia XR, are federally controlled substances (CII) and have a high potential for abuse and dependence.1,2 The selling or giving away of methylphenidate medications may harm others or lead to death, and is against the law. It is important for healthcare professionals to ask patients if they or a family member have ever misused prescription medicines or abused alcohol or street drugs. Patients should be counseled that they should not give Adhansia XR to anyone else, and to keep methylphenidate medications in a safe place, such as a locked cabinet, to help prevent accidental exposure, diversion, and abuse.  They should also be advised to dispose of remaining, unused, or expired Adhansia XR by a medicine take-back program at authorized collection sites such as pharmacies or law enforcement locations, if available. If no take-back program or authorized collector is available, patients should mix Adhansia XR with an undesirable, nontoxic substance to make it less appealing to children and pets, place the mixture in a container such as a sealed plastic bag, and discard of it in the household trash.1 Patients should be encouraged to read the Medication Guide that accompanies their stimulant prescription, which contains the most important FDA-approved information that a patient should know about the medication

Intestinal bacteria can be used to reduce cancer risk, reveals UCLA study

Researchers have shown that various types of intestinal bacteria might be factors in both causing and preventing obesity, and in other conditions and diseases. Now, a UCLA study suggests that it could also potentially be used to reduce the risk for some types of cancer.

The research, published online April 13 in the peer-reviewed journal PLOS ONE, offers evidence that anti-inflammatory "health beneficial" gut bacteria can slow or stop the development of some types of cancer.

Ultimately, doctors might be able to reduce a person's risk for cancer by analyzing the levels and types of intestinal bacteria in the body, and then prescribing probiotics to replace or bolster the amount of bacteria with anti-inflammatory properties, said Robert Schiestl, professor of pathology, environmental health sciences and radiation oncology at UCLA and the study's senior author.

"It is not invasive and rather easy to do," he said.

Over millions of years, gut bacteria have evolved into both good and bad types: The good ones have anti-inflammatory properties and the bad ones promote inflammation. The human body typically contains about 10 trillion bacterial cells, compared with only 1 trillion human cells.

Schiestl and his colleagues isolated a bacterium called Lactobacillus johnsonii 456, which is the most abundant of the beneficial bacteria, and which has some pretty useful applications outside of medicine. "Since it is a Lactobacillus strain, it makes excellent yogurt, kefir, kombucha and sauerkraut."

In the UCLA study the bacterium reduced gene damage and significantly reduced inflammation — a critical goal because inflammation plays a key role in many diseases, including cancer, neurodegenerative diseases, heart disease, arthritis and lupus, and in the aging process.

Previous research led by Schiestl presented the first evidence of a relationship between intestinal microbiota and the onset of lymphoma, a cancer that originates in the immune system. The new study explains how this microbiota might delay the onset of cancer, and suggests that probiotic supplements could help keep cancer from forming.

For both studies, Schiestl and his team used mice that had mutations in a gene called ATM, which made them susceptible to a neurologic disorder called ataxia telangiectasia. The disorder, which affects 1 in 100,000 people, is associated with a high incidence of leukemia, lymphomas and other cancers.

The mice were divided into two groups — one that was given only anti-inflammatory bacteria and the other that received a mix of inflammatory and anti-inflammatory microbes that typically co-exist in the intestines.

In the Cancer Research paper, Schiestl and his team showed that in the mice with more of the beneficial bacteria, the lymphoma took significantly longer to form.

In the new study, the researchers analyzed the metabolites — molecules produced by the gut's natural metabolic action — in the mice's urine and feces. The scientists were surprised to find that the mice that were receiving only the beneficial microbiota produced metabolites that are known to prevent cancer. Those mice also had more efficient fat and oxidative metabolism, which the researchers believe might also lower the risk for cancer.

Intestinal bacteria can be used to reduce cancer risk, reveals UCLA study: Researchers have shown that various types of intestinal bacteria might be factors in both causing and preventing obesity, and in other conditions and diseases. Now, a UCLA study suggests that it could also potentially be used to reduce the risk for some types of cancer.

Health Benefits of Ragi | Medindia

Finger millet (Eleusine coracana L.) also known as Ragi in India is one of the important cereals which occupies the highest area under cultivation among the small millets. The state of Karnataka is the largest producer of ragi in India. Ragi is a crop which can withstand severe drought conditions and can be easily grown throughout the year. Nutritionally, when ragi is used as a whole grain, it is higher in protein and minerals in comparison to all other cereals and millets. It is a remarkable source of protein, making it perfect for vegetarian diets.....

 

Finger millet contains important amino acids viz., isoleucine, leucine, methionine and phenyl alanine which are not present in other starchy meals. It has the highest amount of calcium (344 mg %) and potassium (408 mg %). Ragi is a great source of iron making it beneficial for individuals with low hemoglobin levels.        

Millets also contains B vitamins, especially niacin, B6 and folic acid. Some of the health benefits of ragi are attributed to its polyphenol and dietary fiber contents. Due to its high content of polyphenols and dietary fiber ragi exhibits anti-diabetic and antioxidant and antimicrobial properties; it protects against tumors and atherosclerosis (narrowing and hardening of blood vessels). Being low in fat and gluten free, ragi is easy to digest. It is therefore, given as first foods to babies in the form of ragi porridge.

Malted ragi grains are ground and consumed, mixed with milk, boiled water or yogurt. In southern parts of India, it is a recommended food, by doctors, for infants of six months and above because of its high nutritional content. Homemade ragi malt is one of the most popular infant foods till date.  Malting characteristics of finger millet are superior to other millets. On malting the vitamin-C is elaborated, phosphorus availability is increased, digestion is easier and amino acids are synthesized. In south India, the malted ragi flour is extensively used in preparation of weaning foods, instant mixes and beverages.

Despite finger millet's rich nutrient profile, low cost and easy availability recent studies indicate its lower consumption in general by urban Indians. Obesity has become a matter of health concern in India. Unhealthy foods have increasingly become a part of the food choices made by youth. Large populations of children in the country are malnourished and are deficient in calcium and protein. The millet ragi then could be the answer to all the above problems relating to nutrient deficiencies. Ragi is truly a wonder cereal grain and should be consciously incorporated in the diets in one way or the other.

Coffee, Wine Good for Healthy Gut, Sodas May Be Bad

The food you eat and the medicines you take can alter your gut bacteria in ways that either help or harm your health, two new studies suggest.

Foods like fruits, vegetables, coffee, tea, wine, yogurt and buttermilk can increase the diversity of bacteria in a person's intestines. And that diversity can help ward off illness, said Dr. Jingyuan Fu, senior author of one of the studies.

"It is believed that higher diversity and richness [in gut bacteria] is beneficial," explained Fu. She is an associate professor of genetics at the University of Groningen in the Netherlands.

On the other hand, foods containing loads of simple carbohydrates appear to reduce bacterial diversity in the gut, Fu and colleagues found. These include high-fat whole milk and sugar-sweetened soda.

In addition, medications can also play a part in the makeup of your gut bacteria. Antibiotics, the diabetes drug metformin and antacids can cut down on gut bacterial diversity, the researchers found. Smoking and heart attacks also can have a negative effect, the team said.

Each person's intestines contain trillions of microorganisms, which doctors refer to as the "gut microbiome," said Dr. David Johnson. He is chief of gastroenterology at Eastern Virginia Medical School in Norfolk, Va., and a past president of the American College of Gastroenterology.

The gut microbiome plays an essential but little-understood role in human health, said Johnson, who was not involved with the new studies.

"It's the largest immune system in the body," Johnson explained. "These bacteria have a very dramatic and prominent role in determining health and disease."

To study the effect of lifestyle on the gut microbiome, Fu and her colleagues collected stool samples from more than 1,100 people living in the northern Netherlands.

The samples were used to analyze the DNA of the bacteria and other organisms that live in the gut. In addition to stools, the study collected information on the participants' diets, medicine use and health.

In the second study, researchers with the Flemish Gut Flora Project performed a similar analysis on stool samples taken from 5,000 volunteers in Belgium.

Both studies concluded that diet has a profound effect on the diversity of gut bacteria, although, Fu said, the "underlying theories of these dietary factors remain largely unknown."

Johnson added that medicines can have the same effect, and antibiotics actually can kill off some important strains of gut bacteria. "One dose of an antibiotic may disrupt your gut bacteria for a year," he said.

Both sets of researchers emphasized that their studies only help explain a fraction of gut bacteria variation -- roughly 18 percent for the Netherlands study, and about 7 percent for the Flemish study.

However, the findings from the two groups overlapped about 80 percent of the time, indicating that they are on the right track, the researchers said.

The Belgian researchers estimated that over 40,000 human samples will be needed to capture a complete picture of gut bacteria diversity.

Johnson noted that other research has shown that poor sleep, obesity, diabetes and the use of artificial sweeteners also can interfere with gut bacteria.

"The general rule is a balanced diet with high fiber and low carbs tends to drive a better gut health overall," he said.

According to Fu, once researchers have a clearer understanding of the gut microbiome and its effects on health, doctors could be able to help prevent or heal illness by reading or influencing the bacteria within people's bodies.

"The personalized microbiome may assist in personalized nutrition, personalized medicine, disease risk stratification and treatment decision-making," she said.

Both studies were published in the April 29 issue of the journal Science.
