    When is Someone at Risk for Suicide?

    We are asking ourselves: When is someone at risk for suicide? This year’s National Suicide Week was from Sept. 4 through 10, 2022. Every day of each year it is important to be aware of signs and symptoms of impending suicide. However, the purpose of the yearly National Suicide Week is to really bring it to everyone’s attention how common deaths by suicides are. We all can contribute to improve the situation by increasing our awareness.

    Some suicide statistics

    In the US alone nearly 46,000 persons died by suicide in 2020. This means that there is one death by suicide every 11 minutes. In 2020 nearly 800,000 died by suicide worldwide. About 1.2 million attempted it. The hope is that the public will learn through education to recognize the signs of an impending suicide. This way the suicidal person can get counselling and hopefully not commit suicide.

    Abnormal behaviors to watch out for  

    People who are getting suicidal may practice with guns, overdosing with pills or handle potentially lethal items. Other behavioral red flags could be giving away cherished items. The suicidal person may sleep too much or not enough. Isolation or withdrawal may be another pointer in a previously sociable person that he or she is becoming suicidal. Revenge thinking, reckless driving, agitation can all be pointers as well that the person is preparing for suicide. Justin Baker is the clinical director of The Suicide and Trauma Reduction Initiative for Veterans at The Ohio State University Wexner Medical Center. He said: ”A lot of times people need to kind of work up to that actual making an attempt because it’s a biologic thing you have to go against, your own survival”.

    Watch what people say

    When people become suicidal their words often indicate what they want to do. It is a warning sign, if someone is talking about wanting to die, by suicide or otherwise. Some people state that they feel like they have no reason to live. This is an alarm signal that they may be suicidal. Some people say that they feel like they are a burden for the people living around them. Other problematic statements are: “You don’t need me for this anymore” or “I feel like it’d be better if I just wasn’t here.” Someone uttering statements like these should get counseling. This allows them to vent their feelings and to reassess their situation.

    Suicide risk factors

    Hopelessness: People may express that they feel the future won’t be any better. Or they do not see a way out of the pain that they are in.

    Obsession with death and dying: Some people ruminate about dying and they develop a plan what they may want to do to themselves.  

    Extreme mood swings: When somebody who usually is depressed and stressed behaves calm or cheery, this is an alarm sign that the person may be suicidal. They may have struggled with their decision to kill themselves, but when they accepted that this is what they want to do it calms their mind.

    Past trauma: Abuse, trauma and neglect in the past are risk factors for suicide in the future.

    Drug abuse: substance abuse predisposes a person towards being suicidal later on in life.

    More suicide risk factors

    Severe chronic illness with chronic pain: when a person has a chronic illness, and it is difficult to treat, people lose hope and they feel trapped. At this point suicide appears to be an option.

    Mental disorders: people with schizophrenia, anxiety, depression or personality disorders are at a higher risk to turn suicidal. This is particularly so when they did not receive treatment and their mental condition deteriorates.

    Family history, other factors and teen suicides

    Family history of suicide: when there is a family history of suicide or a personal history of failed attempt of suicides the risk of suicide is much bigger than in the general population.

    Other factors: There are many more factors that all can have a bearing on the risk for suicide. Financial loss and loss of a job are examples, but also prolonged stress from bullying or harassment. Divorce, breakup of a relationship, insufficient social support and many other negative emotions can contribute to a risk for suicide as well. A lot depends on the emotional make-up and the resilience of a person.

    Teens: Teens are particularly vulnerable to commit suicide. It is important to listen to the teen in trouble and to arrange for counseling and support. More on teen suicide here.

    What to do when faced with a person who contemplates suicide?

    There are several crisis phones that are important to remember. In 2019 congress in the US has proposed to establish crisis lines with a simple 3-digit number: 988. But not all states have this number activated yet. The national crisis line in the US is: 1-800-273-TALK (1-800-273-8255).

    In Canada the crisis hotline is: 1-833-456-4566.

    There are counselors who have experience in listening to people in distress and talk to them.

    When a person wants to commit suicide call 911. Sometimes a person in mental distress needs to be hospitalized and treated by a psychiatrist. Some people may benefit from electroconvulsive therapy, others from antidepressants. Cognitive therapy and behavioral therapy have a place as well in treating depressed patients. Close follow-up is important to prevent a relapse.

    When is Someone at Risk for Suicide?

    When is Someone at Risk for Suicide?

    Conclusion

    This year’s National Suicide Week was from Sept. 4 through 10, 2022. In the US alone nearly 46,000 persons died by suicide in 2020, nearly 800,000 died by suicide worldwide. It is important to recognize the signs of impending suicide. There are several high-risk factors that point to impending suicide, such as hopelessness, obsession with death and dying and extreme mood swings. There are certain constellations that are associated with a high risk for suicide: a history of a mental disorder, a break-up of a relationship, a severe illness with chronic pain and others. It is important to get the person at risk to a counselor or psychiatrist.

    Treatment intervention for suicidal person

    By talking it out, the pain of suffering gets eased. If there is an underlying depression it can be treated with various treatment modalities. Cognitive behavior therapy may help to change the negative thought patterns. It is important to intervene early. Close follow-up to prevent a relapse is also important.

    Ultra-Processed Food and Dementia

    Researchers are more and more concerned about an association between ultra-processed food and dementia. A new study found that when you consume more than 20% of you daily food intake as processed food, you can start developing cognitive decline. Eating just 2 cookies per day, which have about 100 calories, will lead to cognitive decline.

    What is processed food?

    Foods such as instant noodles, hot dogs and ice cream are not healthy. There is too much salt, sugar and unhealthy fat in them that undermine your health. If you consider breakfast granola as “healthy”, you’d better take a look at the ingredients: sugar is one of them! Frozen meals, sugary drinks, take-out pizzas, deep-fried chicken and French fries also belong to unhealthy foods. Unless you buy fresh ingredients and make your own Mediterranean-style meals, you will struggle staying healthy. Processed foods lead to weight gain, which is difficult to shed unless you give up processed food.

    Processed food often contains flavorings, colorings or other additives. White bread and bakery products, fried snacks, crackers, cookies, ice cream, candy, cream cheese and processed cheese, soda and frozen meals fall into this category.

    Conference in San Diego

    At the 2022 Alzheimer’s Association International Conference in San Diego researchers revealed the results of a Brazilian study. 10,000 Brazilians were followed with dietary habits and intermittent cognitive tests for up to 10 years. In the beginning none of the participants had a cognitive deficit. The average age at the time of the beginning of the study was 51 years. When you eat more than 20 % ultra-processed food of your total calorie intake every day, cognitive decline is showing up on the cognitive tests. Specifically, patients who consumed more than 20% calories from ultra-processed food developed 28% faster decline in cognitive tests. They also developed 25% faster decline in executive functioning.

    Comment from a co author

    Co Author Dr. Claudia Suemoto, an assistant professor in the division of geriatrics at the University of São Paulo Medical School stated: “In Brazil, ultra-processed foods make up 25% to 30% of total calorie intake. We have McDonald’s, Burger King and we eat a lot of chocolate and white bread. It’s not very different, unfortunately, from many other Western countries”. She went on to say: “58% of the calories consumed by United States citizens, 56.8% of the calories consumed by British citizens, and 48% of the calories consumed by Canadians come from ultra-processed foods”. She expressed her concern that these statistics show that many more seniors than now will develop Alzheimer’s disease. In the Brazilian study researchers followed their subjects for up to 10 years. After decades of exposure to ultra-processed food the numbers of people with cognitive deficits and Alzheimer’s disease will be much higher.

    Other means to prevent cognitive decline

    A study showed that regular aerobic exercises (running, treadmill, walking) or stretching, balancing and range of motion exercises both prevented cognitive decline. The best is to build some form of exercise into your daily routine. This is particularly important for people who have desk jobs.

    What are healthy foods to eat?

    We need to eat more vegetables, fruit and cut out sugar, omit too many starchy foods, salt and unhealthy fats. So, how does that work? In the following I am giving examples of a healthy breakfast, lunch and dinner.

    Breakfast

    Start the day with fresh fruit, a bowl of rolled oats with milk or a milk alternative. Add a few almonds or chopped nuts or ground flaxseed. You could add raspberries, blackberries, strawberries or blueberries.

    If you want a breakfast with egg, try an omelet with eggs or egg white with mushrooms, onions and chopped greens! No, it does not always have to be kale! Enjoy arugula or spinach. Add some salsa on the side.

    For those who hate to prepare breakfast, take it easy: put 1/2 a banana, a cup of berries, 1 tablespoon almond butter and 3/4 cup of low-fat yoghurt into the blender. Blend at high speed. This takes less than 2 minutes. Enjoy! It does not get much easier than that.

    Lunch

    Assemble some mixed salad greens, 1 sliced tomato, 1 cup of sliced cucumber, half a sliced avocado and 1/2 shredded carrot on a plate or in a bowl. Add 2 slices of cheese or 2 tablespoons of crumbled feta cheese. Add one boiled and sliced egg or alternatively 4 slices of chicken breast. Make a dressing of 2 tablespoons of olive oil and 1 tablespoon of balsamic vinegar. You can prepare this easy lunch the evening before and take it to work.

    If you want a warm lunch, cook a simple Italian-style vegetable soup. Sprinkle it with a tablespoon of grated parmigiano cheese and serve it with a slice of whole-grain bread. A vegetable chili is a good choice for a colder day. Have some fresh fruit for dessert.

    Dinner

    Make vegetables the main event. Do not have a huge steak with an afterthought of vegetables, but build a tasty meal around vegetables with a protein of your choice: lean meats, such as chicken breast, enjoy fish or other seafood or experiment with other protein sources, such as tofu. The latter works well in an Asian-style vegetable stir-fry. And otherwise: breaded and deep-fried chicken or battered fish are not healthy choices, even if you prepare the meal at home! Forget the breading and dip the meat into a tasty marinade instead! If you want to have a quick dessert, make a colorful fruit salad with a dollop of yoghurt on top. For all those who drool over a decadent dessert in a restaurant, go ahead and order that Tiramisu and share it with others of your party. But it should be an exception rather than a regular treat.

    Conclusion

    Researchers are more and more concerned about an association between ultra-processed food and dementia. A new study found that when you consume more than 20% of you daily food intake as processed food, you start developing cognitive decline. Eating just 2 cookies per day, which have about 100 calories, will lead to cognitive decline. It is fairly easy to cut out junk foods from your diet and to adopt healthy eating ha its.

    Meal suggestions

    Start the day with fresh fruit, a bowl of rolled oats with milk or milk alternative. Add a few almonds or chopped nuts or ground flaxseed. You could add raspberries, blackberries, strawberries blueberries. I sweeten everything with stevia extract and avoid sugar completely. For lunch you could have mixed salad greens with 2 slices of cheese or 2 tablespoons of crumbled feta cheese. Add one boiled and sliced egg or alternatively 4 slices of chicken breast. For dinner make vegetables the main event. Do not have a huge steak with an afterthought of vegetables, but build a tasty meal around vegetables with a protein of your choice: lean meats, such as chicken breast, enjoy fish or other seafood or experiment with other protein sources, such as tofu.

    Final remark

    You see, it is fairly easy to avoid ultra-processed foods that lead to cognitive decline. It involves a critical look at your current eating habits and very likely some cleaning-out of less than desirable foods from your pantry.

    New Immunotherapy Approach against Cancer

    A recent publication reported about a new immunotherapy approach against cancer. The model it dealt with was a very vicious brain cancer with the name glioblastoma. The results of this research were subsequently transferred to another vicious cancer, osteosarcoma, which is a form of bone cancer with a very poor prognosis. Researchers have to do further clinical experiments to establish this new immunotherapy in osteosarcoma patients. Physicians completed the following experiments and clinical studies.

    Oncolytic virus Delta-24-RGD can lead to remission in glioblastoma patients

    Researchers at the University of Navarra, Pamplona, Spain together with The University of Texas MD Anderson Cancer Center in the US investigated glioblastoma patients. They found that treatment of glioblastoma patients with oncolytic viruses Delta-24-RGD led to a greater than 3-year remission in 20% of cases. Normally, patients with a glioblastoma survive only 9 months on average. 12% had a greater than 95% reduction in the size of the tumor. This was a phase 1 clinical study with 37 patients who had recurrent malignant glioblastoma. The authors said: “Oncolytic adenoviruses are attractive therapeutic agents because they can kill tumor stem cells and induce cell death by several mechanisms, including direct lysis, expression of toxic proteins, induction of cytokines, and T-cell–mediated immunity.” The particular oncogenic virus that the researchers used was an adenovirus Delta-24-RGD.

    Transferring glioblastoma results to a cure for osteosarcoma

    The same researchers wanted to see whether the cure rates of treating patients with glioblastoma was transferable to other cancer patients. In particular they were interested in patients with osteosarcoma, which is a similarly vicious cancer. Advanced osteosarcoma has a survival rate of 27% after 5 years. The researchers first did experiments with a human osteosarcoma cell line in tissue culture and at the same time a murine osteosarcoma cell line. Later they tested the action of oncolytic viruses Delta-24-RGD in a mouse model.

    Experiments with osteosarcoma cells in tissue culture

    The advantage of such experiments is that you can control all the parameters easily in a Petri dish. But critics say that this is far removed from osteosarcoma behavior in humans. Researchers found that the oncolytic virus Delta-24-RGD killed many osteosarcoma cells in vitro. They also were able to insert a new gene into the oncolytic virus, which was equally effective in killing osteosarcoma cells. They called this virus Delta-24-ACT.

    Curing osteosarcoma in a mouse model

    Next the researchers tested effectiveness of the oncolytic viruses, Delta-24-ACT and Delta-24-RDG in mice. They injected osteosarcoma cells from tissue culture into the tibia of mice. Tumor growth was subsequently measured. The experimental groups were given two oncolytic virus infections, the control group did not. On day 10 and 18 the researchers could see that controls had faster growing tumors compared to the experimental groups. The experimental groups had less tumor side effects. And the experimental mice survived longer than the controls. Further research showed that the oncolytic viruses produced a 4-1BBL protein, which stimulated the animals’ immune system to fight the osteosarcoma.

    New immunotherapy approach against cancer: Effector T cells

    Researchers could prove that in mice treated with oncolytic viruses it was the special protein (4-1BBL) that stimulated T lymphocytes to become killer T cells. They in turn attacked the osteosarcoma cells.

    New immunotherapy approach against cancer: The need for human research

    Doing research in humans is more complicated than in a mouse model. But in order to improve survival rates in patients with osteosarcoma human research is absolutely essential. However, research is complex and the effects of oncolytic viruses is only in the 20% range with regard to increasing survival. This requires more research. It may be that instead of oncolytic viruses a stimulatory protein would arm T cells to become killer T cells that fight the cancer.

    New Immunotherapy Approach against Cancer

    New Immunotherapy Approach against Cancer

    Conclusion

    Glioblastoma patients had a better survival after treatment with oncolytic viruses Delta-24-RGD. Researchers translated this type of research to another cancer, osteosarcoma. This also has a poor prognosis, Researchers did experiments in tissue culture and in a mouse model. They were able to show that oncolytic viruses produced a 4-1BBL protein, which stimulated the animals’ immune system to fight the osteosarcoma. Specifically, the protein armed T lymphocytes and turned them into killer T lymphocytes. These destroyed osteosarcoma cells in tissue culture or in the mouse model. It is encouraging to see positive results in a laboratory setting of a tissue culture. The step further in an animal experiment is also a positive achievement. More research will improve the cure rates of osteosarcoma. The effective treatment of osteosarcoma in humans is still far away! The next step is human research that shows improvements in patients’ survival rates.

    What Electronic Cigarettes Do to You

    A review paper of Canadian researchers showed what electronic cigarettes do to you. They can be an effective smoking cessation aid for motivated smokers who eventually want to quit. But when people continue to inhale electronic cigarettes, their use can cause heart attacks, strokes, high blood pressure and increased heart rates. With regard to the lungs electronic cigarettes can cause vaping-associated lung disease, obstructive pulmonary disease, asthma and chronic cough. A literature review showed that e-cigarettes are less harmful to the heart and the lungs than smoking combustible cigarettes.

    Increased use of e-cigarettes in younger people

    In Canada the 2017 Canadian Tobacco, Alcohol, and Drugs Survey, which included all ages, found that 15.4% tried e-cigarettes. But among adolescents between 15 to 19 years old 22.8% were using e-cigarettes. For young adults aged 20 to 24 the figure of e-cigarette users was 29.3%. In addition, there was a significant increase of Canadian adolescents aged 16 to 19 from 29.3% in 2017 to 37.0% in 2018. Data from the US shows similar trends. E-cigarette use among US high school students increased from 11.7% in 2017 to 27.5% in 2019.

    Some facts about e-cigarettes, cigarette smoking and smoking cessation

    • First, researchers noted that the smoking of e-cigarettes has a 3.62-fold risk of leading to subsequent cigarette smoking.
    • Second, a UK study found that when people used e-cigarettes for smoking cessation, 80% of the e-cigarette group were still smoking e-cigarettes after 1 year. In contrast, only 9% of those who used traditional nicotine replacement therapy (Nicorette etc.) to quit smoking were still using nicotine replacement after 1 year.
    • One study compared heart attack rates in a group of regular cigarette smokers and compared this to e-cigarette smokers. Cigarette smokers had a 2.72-fold higher heart attack rate than non-smokers, while e-cigarette smokers had a 1.79-fold heart attack rate compared to non-smokers.

    Effect of e-cigarette use on heart and lung disease

    Several studies looked at the relationship between e-cigarette use, heart attacks and strokes. There was a 1.4-fold higher incidence of coronary artery disease in e-cigarette smokers in comparison to non-smokers. The e-smokers had a 1.71-fold higher stroke incidence and 1.59-fold higher heart attack rates. In a large metaanalysis done with e-cigarette smokers, researchers noted the following facts: Electronic cigarette smokers were compared to non-smokers. Researchers noted a 2.27-fold increase of the heart attack rates in e-cigarette smokers. There was a 2-fold elevation of the systolic and diastolic blood pressure in e-cigarette smokers.

    Switching from cigarette smoking to e-cigarettes

    Patients who switched from tobacco smoking to chronic electronic cigarette use had a 7-fold reduction of their systolic blood pressure and a 3.65-fold reduction of their diastolic blood pressure. The researchers concluded that switching from cigarette smoking to e-cigarettes had some merit in terms of risk reduction for cardiovascular disease. But the final judgment on this is still pending. Certainly, quitting entirely from cigarette smoking is the best choice. I reported previously that e-cigarette smokers find it difficult to quit completely and if they smoke conventional cigarettes to stop that.

    Effect of e-cigarettes on lungs

    In addition to cardiovascular effects there is a direct effect from e-cigarette smoking on the bronchial tubes and the lungs. The vaped substances from e-cigarettes contain a lot of noxious gases that irritate the lining of the respiratory tract. This syndrome is called EVALI (electronic vaping associated lung illness). In 2019 and 2020 there was a rush of EVALI cases in the US with 2807 hospitalizations and 68 deaths. In Canada there were 19 cases of EVALI, 15 hospital admissions, and no deaths. Patients with EVALI have problems breathing, they cough and they have chest pain. Researchers suspect that vitamin E acetate and tetrahydrocannabinol are the major culprits that cause EVALI. But at this time there is no definite proof for that.

    Poor quality of vaping fluid from the black market

    These substances are not present in commercial e-cigarettes, but when you buy vaping fluid on the black market, it is often mixed in. Prolonged use of e-cigarettes can cause changes on spirometry, such as chronic obstructive pulmonary disease (COPD). Chronic use of e-cigarettes may cause premature onset of COPD.

    What Electronic Cigarettes Do to You

    What Electronic Cigarettes Do to You

    Conclusion

    E-cigarette use is increasing at an alarming rate among youths and persons who never smoked. The emerging evidence from researchers showed that there is a risk when you expose yourself to the smoke of e-cigarettes. There is an association of both heart disease and respiratory disease to e-cigarette smoking, but the risk is less than with exposure to regular cigarette smoke. Some researchers think that a switch from cigarette smoking to e-cigarettes could provide a viable harm reduction strategy for some smokers. But unfortunately, many continue to smoke e-cigarettes instead of quitting altogether. And in this case the risks for heart disease and lung disease remain!

    Stem Cell Therapy Is a New Way to Treat Osteoarthritis

    Traditional treatment for osteoarthritis is not very successful, but stem cell therapy is a new way to treat osteoarthritis.

    Traditional treatment of osteoarthritis

    Osteoarthritis is a common degenerative type of arthritis. Wear and tear are diminishing the hyaline cartilage that coats joint bones. The lubrication of synovial fluid is diminishing as well. The end result is that the patient suffers pain from bone rubbing on bone in affected joints with swelling of the synovial membranes. The physician usually prescribes diclofenac topical solution for the affected joints and also gives anti-inflammatory drugs by mouth (diclofenac or ibuprofen). Unfortunately, the patient may develop side effects of the anti-inflammatory medication, such as kidney damage and gastritis. The end result after years of suffering is that the joints turn stiff and the joint pain becomes unbearable.

    Joint replacement surgery

    This is when the doctor refers the patient to an orthopedic surgeon, and an artificial hip or a knee joint replacement is the next suggestion. These surgical procedures are not without dangers. Postsurgically blood clots can develop and cause pulmonary emboli. Infection and sepsis can also develop. Often the surgery does not solve all of the problems and leaves the patient with a permanent limp.

    Stem cell therapy to treat osteoarthritis

    Regenerative medicine has developed an alternative to the conventional treatment of osteoarthritis. I described this new approach to osteoarthritis before here.

    Stem cells are harvested from fatty tissue of the patient and injected into the affected joint. Stem cell stimulators like platelet rich plasma and low-dose laser therapy activate the stem cells that were lying dormant in the fatty tissue. These type of stem cells are mesenchymal in origin, so they go by the name of mesenchymal stem cells. When injected into a joint with osteoarthritis they can transform into any tissue that is needed to repair the damage of the joint. A defect of the hyaline cartilage is covered by stem cells transforming into cartilage cells and fixing the hyaline cartilage defect.

    What stem cells do

    Stem cells fix any meniscal degeneration in the knee joint by mending what is degenerated.  They can form new tissue that overbridged mini tears in the meniscus. If the synovial membranes that produce joint lubrication are damaged, the stem cells rejuvenate the old tissue and joint lubrication normalizes. The end result following stem cell treatment is that the osteoarthritic joint becomes regenerated with normal function. Stem cell treatment normalizes the osteoarthritic process in the joint, and down the road no joint replacements are necessary. This is a huge advantage in comparison to the conventional treatment of osteoarthritis.

    My own experience with stem cell therapy for osteoarthritis of my left knee

    I have experienced mild left knee arthritis for 5 years. It was not severe enough to treat with anti-inflammatory pills. I used higher amounts of fish oil capsules, which helped somewhat. I heard that Dr. Michael Weber from Lauenförde, Germany treats osteoarthritis with stem cell therapy.

    He had treated my back successfully on several occasions in the past. I had previous stem cell treatment 4 years earlier as summarized here.  Part of this was stem cell therapy for my left knee. During the Covid time I could not go to the gym for a period of time. Instead, I went for long walks on a nature trail that was bumpy and had many roots. This flared up my previous problem with my left knee. But in early June 2022 I made my way back to Dr. Weber’s clinic for more stem cell therapy.

    The following summarizes how he treated my left knee with stem cells.

    Liposuction to harvest stem cells for treatment

    The doctor used a local anesthetic to freeze the skin and subcutaneous tissue on the right flank. Subsequently a solution of normal saline that contained adrenaline and bicarbonate was injected. This allowed Dr. Weber to withdraw fatty tissue easier 20 minutes after the normal saline injection. The generous portion of fatty tissue harvested was brought to a cell separator, which separated stem cells, fat cells and connective tissue. The stem cells were counted by a technician. They were found to be 100% viable and there was a total of 980 million stem cells.

    Intravenous stem cells

    Dr. Weber administered one portion of the total stem cell harvest intravenously. I was told that this ensured that stem cells would be delivered to tissues that needed renewal through stem cell therapy. There are several methods to stimulate stem cells. One of these methods is to give oxygen intravenously with a device with the name Oxyven (from Swiss Medica) . This procedure took 20 minutes. A second method to stimulate stem cells is with low-dose laser therapy. Dr. Weber used intravenous red, green, blue and yellow lasers, for 20 minutes each.

    The laboratory kept the rest of the stem cells overnight at room temperature. Dr. Weber told me that it would have been a mistake to keep the stem cells in the refrigerator overnight as the cold temperature kills all of the stem cells!

    Targeted stem cell therapy

    The following day I received treatments with my stem cells harvested the day before. The doctor drew blood up first, which underwent centrifugation. The interface between the red blood cell portion and the plasma contains PRP (platelet rich plasma). Dr. Weber mixed PRP in with the stem cells. PRP is a powerful stimulator of stem cells.

    Dr. Weber inserted a needle into my left knee and injected stem cells (and PRP) into the left knee. Following this he inserted a thin sterile fiberglass applicator. This served to introduce four laser lights into the knee, namely red, green, blue and yellow low-dose laser beams. Dr. Weber connected each for 20 minutes. He explained that the laser light activates the stem cells, similar to PRP and to oxygen (Oxyven, Swiss Media).

    Lower cervical spine, upper thoracic spine and lower lumbar spine also treated

    I get monthly chiropractic manipulations to my spine to stabilize it. My chiropractor told me that it would help to have stem cell therapy in the C4 to T4 area of the upper spine and in the L4 to S1 region in the lower spine. Dr. Weber concentrated his treatments on exactly these levels of my spine. He placed interstitial needles over the facet joints bilaterally in the lower cervical spine, upper thoracic spine and lower lumbar spine. Subsequently he injected the stem cell/PRP mix and followed this up with the four laser lights for 20 minutes each.

    Follow up after the stem cell treatments

    There was a lot of swelling in my left knee during the first two days after the stem cell treatment. I also experienced pain with walking. But on the third day the swelling disappeared completely. After 1 week the previous mild left knee pain improved significantly. After 1 month the left knee no longer ached with stairs or uneven ground. Presently I am still completely pain-free. My back pain also disappeared within 2 to 3 weeks.

    Stem Cell Therapy Is a New Way to Treat Osteoarthritis

    Stem Cell Therapy Is a New Way to Treat Osteoarthritis

    Conclusion

    When it comes to the treatment for osteoarthritis, conventional medicine offers topical and oral anti-inflammatory medicine. Usually, the physician also recommends active exercises and heat applications by a physiotherapist. When anti-inflammatories no longer work and bone rubs on bone in a hip or knee joint, total hip or total knee replacement by an orthopedic surgeon is usually the next step. Unfortunately, these surgical procedures have a certain complication rate. They often do not lead to perfect end results with residual pain and possibly a limp

    Stem cell therapy is usually not what a family practitioner recommends. But when the physician does stem cell therapy at an early stage, the success rate is good and as in my case you can always do another stem cell therapy to improve the knee or hip joint further. There are three procedures that help to stimulate stem cells: platelet rich plasma (PRP), intravenous oxygen (Oxyven, Swiss Media) and low-dose laser activation. In my case Dr. Weber applied all of these methods together with stem cell therapy. Improvement in my case was very rapid, and it was a delight to witness the result of stem cell therapy as a patient.

    Can Surgery Help with Snoring?

    Snoring is a common problem in people, and so the question is: can surgery help with snoring? About 25% of adults snore regularly, 45% snore occasionally. You are more likely to snore when you are overweight. Other factors are being a middle-aged or older male or a postmenopausal woman. Over the last decades various surgical procedures were in development in an attempt to cure snoring.

    Obstructive sleep apnea

    A person with obstructive sleep apnea has a problem of a relaxed rooftop in the mouth, where the uvula drops down. At the same time the tongue is falling backwards and together with the relaxed rooftop this leads to intermittent obstruction of the airway. The end result is loud snoring, which can lead to intermittent cessation of breathing. A positive pressure device is a common remedy for this condition, which keeps the airway open during your sleep. It is called continuous positive airway pressure (CPAP). However, this system is somewhat noisy, and about 50% of patients find it disturbing and cannot tolerate it. Many patients prefer a surgical, permanent solution.

    Classification of snoring

    Most snorers have primary snoring. Among these patients there is a minority who stop breathing periodically, which lowers the blood oxygen content. The patient awakes from this and tightens the muscles in the palatine-pharyngeal area and then breathes normally again for a while. These patients have obstructive sleep apnea (OSA). However, when deeper sleep is reached in OSA patients the cycle repeats itself. A clinical test how to distinguish between primary snoring and OAS is a polysomnography study, which also goes by the name of a sleep study.

    Uvulopalatopharyngoplasty

    This sounds like a tongue twister! In lay terms it is a surgical procedure which removes the uvula and the adjacent tissues of the palate and throat walls. There are side effects like swallowing problems, throat changes and the permanent feeling of a foreign body in the throat. Since the original design several modifications were introduced, which reduce the side effects of this procedure, but do not entirely eliminate them.

    Somnoplasty or radiofrequency ablation

    For patients with primary snoring, who do not have OSA a new procedure utilizes low levels of radiofrequency heat energy to create finely controlled localized burns in the lining of the soft tissues of the palate. This tightens the palate tissue and avoids the vibrations that cause snoring. The procedure can be done in the office setting under local anesthetic. It takes only about 30 minutes. When researchers compared pre-treatment scores with scores after three years following two ablation radiofrequency treatments there was a significant reduction of the snoring activity. Somnoplasty is another name for the FDA approved ablation radiofrequency treatment. This treatment works well for patients with primary snoring, but is not so successful for patients with OSA.

    Maxillomandibular advancement (MMA)

    The physician orders this fairly invasive surgery for patients with OSA who cannot tolerate continuous positive airway pressure. The goal of the surgery is to remove the two obstruction points where the patient chokes at night. This occurs most often behind the palate and behind the tongue. MMA was introduced more than 35 years ago. On the plus side, the success rate is about 90%. The minus side is the fact that it is major invasive surgery where the surgeon moves both the upper and lower jaws forward opening up the two choke points in the back. The surgery lasts about 6 hours and it takes approximately 6 weeks for it to heal.

    Hypoglossal nerve stimulation

    An alternative for patients with moderate to severe OSA is the use of hypoglossal nerve stimulation. Patients with OSA have a weakness in the muscle tone of the muscles that push the tongue forward. When they fall asleep the tongue tends to fall backwards obstructing the airways. This can be remedied with the use of hypoglossal nerve stimulation that stimulates the muscles that push the tongue forward.

    Results with hypoglossal nerve stimulation devices were encouraging, as more than 80% of patients with OAS who had this device inserted had a successful treatment outcome. 4 years later, in the same patients there was still effectiveness of the hypoglossal nerve stimulator and the improvement in quality of life remained the same.

    Can Surgery Help with Snoring?

    Conclusion

    There are several procedures that can help patients with primary snoring or patients with an obstructive sleep apnea (OSA). For patients with primary snoring, who do not have OSA a new procedure utilizes low levels of radiofrequency heat energy to create finely controlled localized burns in the lining of the soft tissues of the palate. This tightens the palate tissue and avoids the vibrations that cause snoring. In patients with obstructive sleep apnea a continuous positive airway pressure device (CPAP) is a common remedy for this condition, which keeps the airway open during their sleep. But only about 50% of patients tolerate this procedure.

    More surgical procedures

    The uvulopalatopharyngoplasty can help a certain number of patients. Here the ear/nose/throat surgeon removes the uvula and the adjacent tissues of the palate and throat walls. The surgeon does this under general anaesthesia, and patients will take about two weeks to fully recover. Another more invasive procedure is the maxillomandibular advancement (MMA). The goal of the surgery is to remove the two obstruction points where the patient chokes at night. This occurs most often behind the palate and behind the tongue. The surgical procedure is in use for more than 35 years and the success rate is about 90%. However the surgery will take several hours, and recovery of the patient will take about 6 weeks.

    Tick Bites Can Render You Allergic to Red Meat

    Tick bites can render you allergic to red meat. This comes from the alpha-gal syndrome, which is a type of food allergy. It is a tick with the name of Lone Star tick that transmits this syndrome in the southeastern United States.

    Deer carries the Lone Star tick into other parts of the US. The bite of the tick transfers a sugar molecule called alpha-gal into the person’s body. Subsequently the person develops a sensitivity to red meat, like beef, pork and lamb. Red meat membranes are rich in the sugar alpha-gal. The allergy can also be directed against other mammal-related products like milk protein. Often the person is unaware of this type of allergy, alpha-gal syndrome. In this case people continue to get exposed to red meat and mammal products, and the immune reactions become more severe over time. Anaphylactic reactions that are not due to food allergies have a high probability to be due to alpha-gal syndrome.

    More details about the alpha-gal syndrome

    Alpha-gal is the abbreviation for Galactose-alpha-1,3-galactose, which is a carbohydrate. It is part of most mammalian cell membranes, except for primates. The immune system in humans recognizes it as a foreign body and produces anti-alpha-gal antibodies. It is the bite of the lone star tick in North America or the castor bean tick in Sweden that can start the allergy to alpha-gal. If a person has frequent anaphylactic reactions, the physician should think of alpha-gal syndrome, which could be the underlying cause.

    Sensitization of the human host

    When the lone star tick bites mice, rabbits or deer it takes up alpha-gal sugar. Subsequently, when the tick bites a human, the alpha-gal sugar is injected into the human host together with its saliva. This alarms the immune system and antibodies are produced. When the human host later consumes meals with red meat, the body reacts to the previous sensitization to alpha-gal sugar by the tick bite. The antibody response to alpha-gal sugar from further red meat meals becomes even stronger than before. The only relief for human host from immune reactions is to switch to a diet that is free of red meat.

    Allergic symptoms

    The alpha-gal allergy can manifest itself by skin rashes, welts, skin itchiness, swelling, shortness of breath, headaches, belly aches, diarrhea and vomiting. In serious cases an anaphylactic reaction can occur, which in some cases can be lethal.

    Protein allergies versus carbohydrate allergies

    Until 2009 medical science believed that allergies would only be due to proteins. One such example are allergic reactions to peanuts. It is the peanut protein that can cause allergies. Subsequently, the alpha-gal allergy became known, which involves the sugar galactose-alpha-1,3-galactose. This was the first sugar molecule that researchers could demonstrate to mount an allergic reaction, from which the human host could turn sick.

    Tick Bites Can Render You Allergic to Red Meat

    Tick Bites Can Render You Allergic to Red Meat

    Conclusion

    The Lone Star tick in the southeastern US carries the sugar galactose-alpha-1,3-galactose (for short alpha-gal) which originates from bites of mammals that are not primates (cattle, pigs and lambs). When the tick bites a human, the immune system produces antibodies against alpha-gal. This can produce skin rashes, welts, skin itchiness, swelling, shortness of breath, headaches, belly aches, diarrhea and vomiting. But when the person recovers from the tick bite, a lifelong sensitivity against reed meats remains. Every time a sensitized person consumes a red meat meal the same symptoms, as originally experienced from the tick bite, return.

    Abstinence from red meat

    The only remedy for the alpha-gal syndrome is to abstain from red meat. The cell membranes of the muscle of red meat contain the sugar alpha-gal. Seafood, chicken, eggs and turkey meats are OK for consumption. But the patient has to be diligent about not making any dietary mistakes. If intermittent red meat exposure continues, a more severe allergy can develop. These have the name of “anaphylactic reactions”, where the patient is in danger of suffocating or even die from it.

    Erectile Dysfunction Drugs Pose a Risk to Eyes

    A new study from the University of British Columbia, Vancouver, BC showed that erectile dysfunction drugs pose a risk to eyes. UBC researchers studied 213,000 insurance claims of serous retinal detachment, retinal vascular occlusion, and ischemic optic neuropathy. They found that there was a close association with these eye conditions and the use of drugs like Viagra, Cialis, Levitra, and Stendra that these men used for erectile dysfunction (ED). In the year before these men started to take ED drugs none of them had any of these three eye conditions. Once they started taking these drugs there was an 85% increase in occurrence of one of these eye conditions.

    Explanation of eye conditions

    Serous retinal detachment

    Serous retinal detachment can occur when you develop a tear of the retina. In this case the vitreous fluid from the center of the eye can leak underneath the retina and lead to retinal detachment. If you develop spots or floaters or flashes of light, or if you develop weak vision, this is a sign that you should seek immediate help from an eye-specialist.

    Retinal vascular occlusion

    When a blood clot occurs in either a vein or artery that supplies the retina with blood there can be a sudden loss of vision. This is an emergency and requires a trip to an eye specialist in the hospital.

    Ischemic optic neuropathy

    The optic nerve collects all the signals from the retina and transports this to the brain for further processing. When the blood supply to the optic nerve gets interrupted, there can be a sudden loss of vision. This is an emergency. An eye specialist has to immediately assess the patient in the hospital.

    Eye professor warns to take eye conditions seriously

    Professor Dr. Mahyar Etminan from UBC said: “These are rare conditions, and the risk of developing one remains very low for any individual user. However, the sheer number of prescriptions dispensed each month in the U.S. – about 20 million – means that a significant number of people could be impacted.” He went on to say: “Regular users of these drugs who find any changes in their vision should take it seriously and seek medical attention.”

    Causation versus statistical association

    The study showed a strong statistical association between the ED drug use and these three eye conditions. Patients on the ED drugs were 1.85-fold more likely to develop one of the eye conditions. This was in comparison to controls who were not on ED drugs. Professor Etminan said: “These medications address erectile dysfunction by improving blood flow, but we know that they can also hinder blood flow in other parts of the body”. And he continued: “So although our study doesn’t prove cause and effect, there is a mechanism by which these medications could conceivably lead to these problems. The totality of the evidence points toward a strong link.”

    Erectile Dysfunction Drugs Pose a Risk to Eyes

    Erectile Dysfunction Drugs Pose a Risk to Eyes

    Conclusion

    When men age, they often develop erectile dysfunction (ED). ED drugs were developed that can overcome this problem. But like any drug these can have side effects too. One of the rare side effects are three serious eye conditions. The have the name serous retinal detachment, retinal vascular occlusion, and ischemic optic neuropathy. As these men were older, they likely already had some arteriosclerosis of the blood vessels. This means they were at a higher baseline risk to develop one of these eye conditions. A study showed that they were 1.85-fold more likely to develop one of the eye conditions. This was in comparison to controls who were not on ED drugs. At this point the researchers at UBC Vancouver, BC say that they found the following. There was a strong association between ED drugs and these serious eye conditions. They commented that at the present time, however, they cannot say that ED drugs would have caused them.

    What Works for Permanent Weight Control

    A recent publication examined what works for permanent weight control and what not. The study came from the Queen’s University in Kingston, Ont., AdventHealth, Fla. and the University of Alabama, Birmingham, Ala.

    320 sedentary adults who were overweight or had obesity were treated by monitoring alone or by doing “small change approaches”. Both groups were observed for 3 years. The “small change approach” consisted of increasing their activity by 2000 steps per day and by limiting their food intake by 100 kcal per day. The researchers measured the weight, waist circumference and cardiorespiratory fitness of all the subjects.

    The results at 3, 6, 12 and 15 months from the start showed significant reductions in weight. However, by 24 and 36 months the subjects had regained body weight.

    Results of the study

    Results from both groups, the non-intervention group and the small change group, were stacked against each other. There was no significant difference in terms of weight loss between 24 and 36 months into the trial. The researchers concluded that the approach of small change interventions failed.

    Another approach to permanent weight loss

    Valter Longo, a professor at UCLA, California has established that the fasting mimicking diet can help people to lose the last pounds that are difficult to lose. Patients do a 5 day semi-fast for 5 consecutive days, once per month. They eat three meals per day, but the total daily calorie consumption is only 500 to 800 calories. The calorie deficit leads to a reduction in body mass index between 0.3 and 0.9 for every monthly fasting mimicking diet. I have followed Dr. Longo’s fasting mimicking diet since December 2017. This allows me to keep my body mass index between 21.0 and 22.0.

    Conditions that respond to the FMD

    The following list shows some of the conditions that respond favorably to the FMD.

    • Obesity, because of the weight loss effect
    • Diabetes: insulin resistance becomes lower and blood sugar levels drop.
    • High blood pressure reduced: many patients were able to reduce their medications or discontinue them
    • Prevention of heart attacks and strokes
    • Pain conditions improve as all kinds of pain disappears, an effect for which there is no explanation at this point
    • Autoimmune diseases like MS and rheumatoid arthritis improve, likely because of the effect of increased stem cell circulation
    • Prevention of heart attacks because of reduction of LDL, triglycerides and CRP
    • Cancer cure rates improved by protecting normal cells and bone marrow function
    • Longevity improved in mice with a 3-fold increase of their life span. Telomere length in humans was increased. Increased stem cells will find defective areas that need repair. This effect opens up a new chapter in medicine.

    The above was previously published here.

    Discussion

    The 3-year study that I mentioned at the beginning of this article showed that for the group that made “small changes” for 2 years there was a slight weight loss with a reduction of 100 calories per day. However, the patients got tired of dieting and regained their lost weight between 2 and 3 years. In contrast, the fasting mimicking diet requires a 1200 to 1500 calorie reduction for 5 days of each month. After a few months the patient becomes highly aware what leads to weight gain and what not. I use electronic body composition scales daily where I can determine weight, fat percentage and muscle percentage. It also records calories consumed and the body mass index (BMI).

    Watching your fat percentage and BMI

    I record all this data in a little booklet. Once per month I see that the fasting mimicking diet lowers my body mass index by 0.3 to 0.9 points. There is the negative experience of eating ice cream or a New York cheesecake that within one day shows as an increase in fat and the BMI. On the other hand, it is encouraging to see your elevated BMI melt away in only a few days every month. This motivates you over the years to cut out the big diet offenders and to keep your eating portions smaller. Also, you value the neutral effect of berries and vegetables.

    What Works for Permanent Weight Control

    What Works for Permanent Weight Control

    Conclusion

    An interesting diet study of 3-year duration showed that small caloric reductions of 100 calories per day are ineffective over a longer period of time. In this study the effect of small caloric reductions wore off after two to three years. On the other hand, I experienced the effects of the fasting mimicking diet (FMD) of Dr. Longo for more than 4 years. This helps me to keep my body mass index (BMI) in the 21.0 to 22.0 range. Without the FMD I would slowly slip into the overweight category. Following the FMD every month and recording the body composition scale values daily keeps me motivated to watch what I eat resulting in persistently low BMI values. Knowing that this is also a key to health keeps should keep anybody motivated.

    The Dirty Dozen and the Clean Fifteen

    This article describes the dirty dozen and the clean fifteen.

    The environmental working group (EWG) defined the “dirty dozen” as crops, which farmers pollute by repetitive spraying. Notably, this is a list of the 12 most insecticide-sprayed crops like strawberries, spinach, tomatoes and others. It is important to realize that in the last few years, the EWG added the 15 clean crops. For this reason, if you want to avoid toxins on your food you exchange the 12 dirty dozen for organically grown crops. Specifically, you can also rest assured that the pollution levels in your food is of no concern, when you add the “clean fifteen” since these crops are relatively non-polluted. By all means, I have used this shopping guide for over 10 years and always look for the yearly updates.

    The dirty dozen

    Here is the dirty dozen:

    1. Strawberries
    2. Spinach
    3. Kale, collard & mustard greens
    4. Nectarines
    5. Apples
    6. Grapes
    7. Bells and hot peppers
    8. Cherries
    9. Peaches
    10. Pears
    11. Celery
    12. Tomatoes

    It is important to realize that certain agricultural methods lead to the insecticide contamination of the dirty dozen. It may come as a surprise that not only spinach, strawberries and cherries, but also apples, grapes, celery and tomatoes are very contaminated. I buy only organic equivalent versions of the dirty dozen.

    The list of the clean fifteen

    Here is the list of the clean fifteen:

    1. Avocados
    2. Sweet corn
    3. Pineapple
    4. Onions
    5. Papaya
    6. Sweet peas (frozen)
    7. Asparagus
    8. Honeydew melon
    9. Kiwi
    10. Cabbage
    11. Mushrooms
    12. Cantaloupe
    13. Mangoes
    14. Watermelon
    15. Sweet potatoes

    These are crops that you can buy and eat, because they are not contaminated with insecticide spray. There is a yearly update on the website, which informs you of any changes of the contaminated crops. So far little has changed over several years.

    According to the CNN article cited in the beginning of this article 70% of the clean fifteen list have no detectable residues of pesticides. Just under 5% of this list had two or more pesticide residues. For this reason I would label those as relatively non- polluted.

    Why pesticides are dangerous

    Toxicity of pesticides depends on the chemical configuration. Some are more toxic than others. But in combination pesticides are much more toxic than each one of them alone. Some pesticides irritate the skin, others the eyes. Other chemicals are toxic to the nervous system and the hormone system. And on the long-term pesticides can cause cancer.

    Specific toxins

    • DCPA http://extoxnet.orst.edu/pips/DCPA.htm is a general herbicide that farmers spray on several vegetable crops. It was banned by the European Union in 2009.
    • Nut and fruit tree farms use Chlorpyrifos, a pesticide, which farmers also spray on broccoli and cauliflower. The EPA banned this substance in February 2022. Chlorpyrifos contains an enzyme that causes neurotoxicity in children. It also causes neurodevelopmental effects in children.
    • Organophosphates block acetylcholinesterase, an enzyme that inactivates acetylcholine. Toxicity of organophosphates comes from poisoning with acetylcholine, which overstimulates muscles. https://en.wikipedia.org/wiki/Organophosphate_poisoning#Pathophysiology The brains of babies and children are very sensitive to the toxic effect of organophosphates.
    • A number of pesticides are endocrine-disrupting chemicals. This can have permanent or long-lasting effects on the reproductive development. https://cfpub.epa.gov/si/si_public_record_report.cfm?Lab=NHEERL&dirEntryId=212273

     Complaints of the industry about the EWG

    The industry has repeatedly complained about the EWG that the publication of the dirty dozen would harm the sales of crops. But studies done by the EWG showed that only 1 in 6 consumers are buying less vegetables and fruit. Alexis Temkin, a toxicologist at the EWG with expertise in toxic chemicals and pesticides said: “The study actually shows that just over half of people surveyed said the ‘Dirty Dozen’ list made them more likely to buy fruits and vegetables.”

    Here is what the consumer can do  

    • Rinse fruit and vegetables before you serve it; this removes surface toxins
    • Buy food from a local farmer; you can enquire about his farming practices.
    • Buy produce in season; if you buy organic crops they are most reasonable are that time, and you can prepare or freeze the fruit and vegetables for future use.
    The Dirty Dozen and the Clean Fifteen

    The Dirty Dozen and the Clean Fifteen

    Conclusion

    The environmental working group (EWG) developed the concept of the 12 dirty dozen and the clean fifteen crops. The consumer needs to know the 12 dirty dozen, as he/she has to buy organic crops as a replacement for this. On the other hand, you can buy the 15 clean crops, but you first need to know what is on the list. Knowledge is power, and knowing about these crops ensures that you keep insecticides, fungicides and herbicides out of your body. This information is not only important for adults and youth, but particularly important for babies and small children. Chlorpyrifos, which was banned in February of 2022 in the US causes neurotoxicity in children. But it also causes neurodevelopmental effects in children. The cleaner the crops are that we eat, the healthier our bodies are.
