Robotic GPS system for early lung cancer detection.
Lung cancer typically is diagnosed at a later stagethan other malignancies, due to the lack of early warning indications. In 2020 it was China’s most common cancer and the leading cause of cancer-associated mortality. LungHealth MedTech, a medical robotics company in Shanghai, has developed a robotic-assisted bronchoscopy platform that can address some of the current diagnostic challenges and treatment limitations.

Keeping bones healthy is important for everyone and especially important for people with Parkinson’s. We share some top tips for keeping your bones in tip top condition.
Bone health really means having ‘healthy bones’. Healthy bones are strong enough to prevent fractures, for example when we have a fall. Our bones are more healthy when we have enough calcium in our diet (from milk, and dairy products like cheese) and when we use our arms and legs (such as with exercise).

Take an animated look inside the neuron, and learn how scientists are addressing brain disease. With approximately 86 billion neurons in the brain, humans contain the most complex communications network imaginable. To address diseases of brain development and degeneration, neuroscientists are investigating how and why this network breaks down, and what can be done to repair it.
One area of study is dendrites, which are the tree-like structures of neurons, that receive electrical impulses. Researchers are carefully mapping out brain circuits and uncovering how connectivity changes can result in defects of the visual system or behavioral problems. The core section of the neuron is the cell body. Genetic engineering tools are revealing how mutations impact brain development and contribute to autism spectrum disorder or rare, inherited forms of neurological disease.
The transmission of nerve impulses occurs along the axon, which is insulated, much like an electrical wire, by a fatty layer called the myelin sheath. Scientists have invented a medicine to stop the immune system from mistakenly attacking this layer, which occurs during multiple sclerosis. Other molecules currently in development instruct the body to regenerate the sheath and repair damage. The axon also transports valuable cellular cargo, such as neurotransmitters, along tracks from one end of the neuron to the other.
Researchers are testing drug candidates for their ability to remove molecular traffic jams when this transport system fails, as often occurs in Parkinson’s and Alzheimer’s disease. The axon terminals make connections called synapses with other cells, using neurotransmitters as signals. Some scientists are evaluating how finely tuning the receptors for these chemicals could ease depression and anxiety.
Others are finding ways to promote the regrowth of lost synapses, which could halt neurodegeneration. From genetics to behavior, neuroscience is accelerating new interventions for the most challenging disorders of the nervous system.

The New England Journal of Medicine is the world’s leading general medical journal.
Continuously published for over 200 years, the Journal publishes peer-reviewed research along with interactive clinical content for physicians, educators, and the global medical community at https://NEJM.org.
COMMENTARY:
This is a very good video well worth watching by general physicians and interested patients. There are several general and some specific comments I would like to make.
First, in my opinion, the best physician is none too good. In any operative or serious procedure, the decision to operate should be made by the patient in conjunction with a physician that does not do the operating. In my case, as a physician, I consulted an electrophysiologist.
Second, in my opinion, a good medicine is better than surgery. For atrial fibrillation, there has been no new medication treatment for decades. The main drugs are still amiodarone and Propafenone. The latter is less consistently effective, but has a better long-term safety profile; amiodarone often produces ‘floaters” in the eye, and Propafenone merely a bitter taste which you’ll get used to.
Third, it must be realized that catheter ablation is often not curative, especially as you get older, which was rather glossed over in this video. Ablation also requires a great deal of expensive equipment, which is constantly evolving, hence the importance of getting your ablation at a major center where it is done all the time. These major centers have less complications such as atrial wall perforation; Yes, you can rarely wind up worse off after any operation.
I am a physician, currently 90 years old. I developed atrial fibrillation of the persistent type when I was in my late 70s. I had a cardioversion to get me into sinus rhythm, and then tried Propafenone, which kept me in sinus rhythm for less than a month. My main motivation to get a radio frequency ablation was to stay off of anticoagulants. I had my ablation, and remained in sinus rhythm, and off anticoagulants, for three years. I could always tell when I went into atrial fibrillation from normal sinus rhythm because I produced a lot of urine and had to go to the bathroom all the time; atrial fibrillation causes release of a hormone called atrial naturetic peptide. I could also tell by taking my own pulse, which was quite irregular in comparison to my very regular sinus rhythm pulse, which ticked along with a rate in the high 50s. I had always thought my rate was low because I exercise a lot. Actually, my EKG shows a second-degree heart block which is probably partially responsible.
After three years, I returned to atrial fibrillation, and needed a another ablation. They found very few areas of abnormal electrical activity, and gave me a “touchup”, which lasted another two or three years after which I went back into atrial fibrillation. Probably as a result of my age, a fibrillated at a slow rate, and at least did not need any extra medication for rate control, although I did, of course, need to take a regular anticoagulant, in my case Eliquis.
In summary, atrial fibrillation is a common electrical storm in the upper chambers of the heart, causing a rapid, irregular beat. AF increases in frequency as you get older. In the video they mention the “substrate”, which is the structure of the atrium. In my own case, this was an enlarged atrium, and probably a tendency towards atrial fibrillation; my brother also has AF. The main complication is stagnation of blood in the atria, resulting in increased tendency toward stroke. Fibrillation therefore requires an anticoagulant.
There is some discussion about the irregular rate causing an inefficiency of cardiac action, contributing to heart failure, This is logical, but not clear cut statistically.

A women’s lifetime risk of developing breast cancer is one in eight. Research has shown that the earlier you detect breast cancer the more options there are for treatment and a better chance for a cure.
A mammogram is a low-dose X-ray of breast tissue. Healthcare providers use mammograms, or mammography, to look for early signs of breast cancer before symptoms develop. This is called a screening mammogram. Providers also use mammography to look for any abnormalities if you develop a new symptom, such as a lump, pain, nipple discharge or breast skin changes. This is called a diagnostic mammogram.
Aside from skin cancer, breast cancer is the most common cancer that affects people assigned female at birth and represents 14% of all new cancer diagnoses in the United States. While breast cancer treatment therapies continue to improve and have contributed to a reduction in cancer-related deaths, early diagnosis through screening mammograms has a greater overall impact on survival rates.

Daniel Wiznia, MD, an orthopaedic surgeon with Yale School of Medicine, is practicing a surgical technique designed to render 10% of hip replacements unnecessary. Regenerative properties from a patient’s own stem cells are responsible for regrowing bone, restoring blood flow, and being able to avoid further interventional surgery.
Osteonecrosis, also known as avascular necrosis, occurs in more than 20,000 Americans each year. As the condition progresses, bone cells known as osteoblasts become unable to repair themselves and sustain the integrity of the bone, and ultimately die. The bone deterioration leads to a decrease in blood flow to the area, further weakening the entire skeletal structure of the upper leg.
If unaddressed, the ball portion of the hip’s ball and socket joint will cave in on itself and collapse, requiring a total hip replacement. The fact that patients often receive this diagnosis during their 30s and 40s presents a particular challenge.
While the lifespan of hip prosthetics has dramatically increased in recent years, a patient who undergoes a total hip arthroplasty, or total hip replacement, at that age will almost certainly require a revision later in life. This redo of the same surgery at an older age comes with an entirely new set of risks and potential complications, making it that much harder to manage down the road.

COMMENTARY:
Hypertension is an elevation of the blood pressure in the arteries. It is measured conventionally by blood pressure cuffs, although a catheter in the artery is more accurate. I’ve had my blood pressure taken countless numbers of times by nurses and doctors who sometimes put the cuff on my arm through a piece of clothing, making it less accurate. Sometimes it is taken by an automatic blood pressure cuff even in the doctors office. The automated cuff can be purchased for $20 or less for you to use it at home, but it’s accuracy is questionable when you have an irregular heartbeat with atrial fibrillation such as I do.
The blood pressure reading which is considered to be normal Is dropping. In the present video, following 2017 guidelines , they state that a systolic reading of more than 120 mmHg is elevated, and anything more than 130 is hypertension. It may be true that studies have been done to show that these slight elevations cause problems, but so can the drugs that are used to lower blood pressure; a cough can be caused by ACE inhibitors. Fatigue and fainting can be caused by an excessive dosage of any blood pressure medication.
Healthy diet, especially avoiding extra salt, Regular exercise and good sleep will go a long way towards keeping your blood pressure at 120 or below on the high reading (systolic), and 80 on the low reading (diastolic).
My systolic blood pressure varies between 120 and 140 systolic, and is usually around 60 diastolic. For a long time I thought the relatively low (diastolic) blood pressure was more important, since diastole is of greater duration than systole, but it has now been determined that the systolic blood pressure reading is the one to worry about. Calcification and lack of elasticities in the arteries as you get older can lead to higher systolic blood pressure.
It used to be thought that the normal systolic blood pressure was 100+ your age in years. Those days are gone, however, and greater life expectancy and health Is one result of carefully monitoring your blood pressure, and working hard to keep it down.
