A weekly podcast on the latest medical, science and telehealth news.
Technology: AI Offers Window On Heart Health
AI can pick up on subtle clues from a person’s physiological state such as their heart rate, the time differences between each heartbeat or the electrical signals their heart produces in order to identify irregularities that point to medical conditions.
“Being able to detect atrial fibrillation just by wearing a wristwatch all the time, that kind of relatively simple technology could actually have a massive impact,” explained consultant cardiologist Tim Fairbairn, cardiovascular imaging lead at Liverpool Heart and Chest Hospital in the UK.
Diet: What You Need To Know About Cholesterol
Mayo Clinic Minute – What you need to know about cholesterol.
Cholesterol is any of a class of certain organic molecules. A cholesterol is a sterol, a type of lipid. Cholesterol is biosynthesized by all animal cells and is an essential structural component of animal cell membranes. When chemically isolated, it is a yellowish crystalline solid.
Diagnosis: The Causes Of Fever Of Unknown Origin
Fever is just one of the number of symptoms that accompany most infections such as Covid and influenza. When doctors can’t find a diagnosis for the fever, and it lasts for a few weeks, however, it is called fever of unknown origin, or FUO.
There are a bewildering number of illnesses that produce fever, and the mixture of these illnesses is different depending on geographic location, the type of hospital, and socioeconomic conditions.
Just like weight loss of unknown origin, or abdominal discomfort of unknown origin, fever without obvious cause is quite possibly be due to cancer in affluent America, and if you go in early you might have better outcomes with your treatment.
Fever has been known since earliest times, and was often considered a diagnosis on its own. In the past, the great majority of the fevers were infectious, and the outcome grave. In the mid 20th century, when I went to medical school, fevers were still mostly infectious. Antibiotics were the magic bullet, and were unfortunately overused. In underdeveloped countries, infections are still the most common cause, but in the developed world difficult to treat viral infections, autoimmune conditions, and cancer have been gaining in prominence.
When fever becomes excessive, and medication is needed, NSAIDS may be used, and works better on fever from infection than on fever from cancer. The take-home message for me is that if you use Naprosyn for a persistent fever, and isn’t effective, you might notify the doctor.
The motivation for me writing this article came from a very good posting in the New England Journal of medicine. They used a little humor, stating that modern FUO might be called “fever of too many origins”, what with all the indwelling catheters, implanted medical devices, shunts and long hospital stays. There is a separate category made for fever acquired in the hospital.
In people with AIDS, the evaluation is different depending on whether or not they are on treatment.
Tuberculosis is still a very common cause of fever.
Drugs are becoming increasingly responsible for troublesome fevers. In the early days of antibacterial therapy, sulfa was the only drug available, frequently caused fever. Now, sulfa is less used, and the penicillin derivatives are more common causes of fever.
If you have a fever, and have been traveling recently, be sure to tell the doctor. Your fever might be due to a tropical parasite such as malaria, particularly if you’ve been to West Africa.
Fever is an evolutionarily conserved body defense reaction and helps a person recover from an infection. The normal body temperature cycles according to the time of day; it is lowest first thing in the morning, and is higher later in the afternoon. The average body temperature used to be 37°C, or 98.6 F., but has been declining in recent decades, and is now about 36.5°C or 97.6°F. The use of electronic thermometers has cut down the amount of time needed to assess the body temperature, but added variability. I still prefer the old-fashioned thermometer.
Taking your temperature by whatever means you have available still remains a good idea when you don’t feel well.

Clinical: Yale Women’s Heart Health Program
The Women’s Heart and Vascular Program provides state-of-the-art cardiac care for women with heart disease, as well as expert screening of women at risk for heart disease.
Heart disease remains the number one killer of American women and there is a great need for specialized care directed at women’s cardiac needs. The Women’s Heart and Vascular Program is dedicated to screening, educating and treating women at risk for, or with established heart disease.
Under the direction of Lisa A. Freed, MD, FACC, the Women’s Heart and Vascular Program incorporates not only her expertise in cardiology, but also collaborates with experts in diabetes, menopause, nutrition, exercise physiology, and smoking cessation. In addition, Dr. Freed consults with experts in sleep apnea and mental health professionals for intervention with co-existing depression and anxiety.
The program also focuses on clinical research in collaboration with Yale’s Women’s Health Research Center in order to advance the care of women with heart disease.

Blood Circulation: What Is Raynaud’s Phenomenon?
Raynaud’s phenomenon: Not just poor circulation
When you’re exposed to a cold environment, your body reacts by trying to preserve your core temperature. Blood vessels near the surface of your skin constrict, redirecting blood flow deeper into the body. If you have Raynaud’s phenomenon, this process is more extreme, and even slight changes in air temperature can trigger an episode, says rheumatologist Dr. Robert H. Shmerling, senior faculty editor at Harvard Health Publishing and corresponding faculty in medicine at Harvard Medical School.
“Cold weather is the classic trigger for Raynaud’s phenomenon. But it can occur any time of year — for example, when you come out of a heated pool, walk into an air-conditioned building, or reach into the freezer section at the supermarket,” he says. In addition to the hands, Raynaud’s can also affect the feet and, less often, the nose, lips, and ears. During an episode, the small arteries supplying the fingers and toes contract spasmodically, hampering the flow of oxygen-rich blood to the skin. Some of these vessels even temporarily collapse, and the skin becomes pale and cool, sometimes blanching to a stark white color.
