FROM SURVIVAL TO QUALITY OF LIFE: WHY OUTCOMES ARE BEING REDEFINED THE FUNDAMENTAL SHIFT IN MEDICINE For decades, medicine measured success through a singular lens: survival. Did the patient live? Did the procedure work? While these metrics remain important, healthcare is undergoing a profound transformation that redefines what "winning" actually means[1]. The new standard is no longer just extending life—it's enabling patients to live purposefully, functionally, and with dignity[2]. This shift reflects a critical insight: surviving is not the same as living well. WHY OUTCOMES ARE BEING...

Ai in Medicine Tool Partner or Problem
PodcastDX
AI in medicine is best understood as a powerful tool and a conditional partner that can enhance care when tightly supervised by clinicians, but it becomes a problem when used as a replacement, deployed without oversight, or embedded in biased and opaque systems. Whether it functions more as a partner or a problem depends on how health systems design, regulate, and integrate it into real clinical workflows. Where AI Works Well Decision support and diagnosis: AI can read imaging, ECGs, and lab patterns with very high accuracy, helping detect cancers, heart...

Medicine in Transition:
PodcastDX
Medicine has transitioned due to massive tech adoption (Electronic Health Records EHRs, Artificial Intelligence AI, Telehealth), shifting patient expectations (consumerism, convenience), the rise of value-based care, new treatments (precision medicine), and increased focus on population health and prevention, all while grappling with rising costs, data security, and persistent access/equity gaps, making healthcare more data-driven, personalized, and digitally integrated but also more complex and fragmented. We try to break it down to try and understand the changes and how they might...

A Primer on Stem Cells
PodcastDX
This week we discuss stem cells. Having great therapeutic and biotechnological potential, stem cells are extending the frontier in medicine. Not only replace dysfunctional or damaged cells, the so-called regenerative medicine, stem cells may also offer us new perspectives regarding the nature of aging and cancer. This review will cover some basics of stem cells, their current development, and possible applications in medicine. Meanwhile, important remaining challenges of stem cell research are discussed as well. Stem cells are unique, unspecialized cells that can divide to create...

Functional Fitness
PodcastDX
This week we will discuss the topic of "functional fitness" With the new year upon us many people want to add fitness or getting healthy as goals and we are here to help! Functional fitness is a simple, effective way to keep your body moving and reduce restlessness. It focuses on exercises that help you perform everyday activities more easily and safely—like getting up off the floor, carrying groceries, or reaching for items on a shelf. By training your muscles to work the way you actually use them in daily life, functional fitness reduces injury risk and improves overall quality of...

Why New Year Resolutions Often Fail
PodcastDX
By the end of the first week of the new year, nearly 77% of New Year’s resolutions have already failed (Norcross, 1988). That’s discouraging—but it doesn’t mean you should stop trying. It means most of us are setting resolutions in ways that don’t work. You aren’t weak or lazy. More often, the problem is a misaligned system—one that relies too heavily on willpower and short-lived motivation. Motivation naturally fades over time, even when our intentions are good. Think about how often you enthusiastically agree to plans weeks in advance, only to feel tired or unmotivated when...

The Lymphatic System
PodcastDX
The lymphatic system, or lymphoid system, is one of the components of the circulatory system, and it serves a critical role in both immune function and surplus extracellular fluid drainage. Components of the lymphatic system include lymph, lymphatic vessels and plexuses, lymph nodes, lymphatic cells, and a variety of lymphoid organs. The pattern and form of lymphatic channels are more variable and complex but generally parallel those of the peripheral vascular system. The lymphatic system partly functions to convey lymphatic fluid, or lymph, through a network of lymphatic channels,...

Pancreatic Cancer
PodcastDX
This week we are talking about Pancreatic cancer. This is a type of cancer that begins as a growth of cells in the pancreas. The pancreas lies behind the lower part of the stomach. It makes enzymes that help digest food and hormones that help manage blood sugar. The most common type of pancreatic cancer is pancreatic ductal adenocarcinoma. This type begins in the cells that line the ducts that carry digestive enzymes out of the pancreas. Pancreatic cancer rarely is found at its early stages when the chance of curing it is greatest. This is because it often doesn't cause symptoms until...

Diabetes Type 1 & 2
PodcastDX
This week we discuss diabetes mellitus, a group of diseases that affect how the body uses blood sugar (glucose). Glucose is an important source of energy for the cells that make up the muscles and tissues. It's also the brain's main source of fuel. The main cause of diabetes varies by type. But no matter what type of diabetes you have, it can lead to excess sugar in the blood. Too much sugar in the blood can lead to serious health problems. Chronic diabetes conditions include type 1 diabetes and type 2 diabetes. Potentially reversible diabetes conditions include prediabetes and gestational...

Mast Cell Activation Syndrome MCAS
PodcastDX
Mast cell activation syndrome (MCAS) is when you have unexplained episodes of severe symptoms like swelling, diarrhea, vomiting, flushing and itching. Unlike that happen with a specific exposure, MCAS episodes happen without a clear trigger. In some cases, mast cell activation can cause , a severe allergic condition that can be life-threatening. It can cause you to have trouble breathing and drop your to dangerously low levels. Call 911 (or your local emergency service number) or go to the nearest emergency room if you’re experiencing severe anaphylaxis. are a type of immune cell...

Bartonella is a genus of Gram-negative bacteria. It is the only genus in the family Bartonellaceae. Facultative intracellular parasites, Bartonella species can infect healthy people, but are considered especially important as opportunistic pathogens. Bartonella species are transmitted by vectors such as fleas, sand flies, and mosquitoes. At least eight Bartonella species or subspecies are known to infect humans. Bartonella henselae is the organism responsible for cat scratch disease.
History
Bartonella species have been infecting humans for thousands of years, as demonstrated by Bartonella quintana DNA in a 4000-year-old tooth. The genus is named for Alberto Leonardo Barton Thompson (1871–October 26, 1950), a Peruvian scientist.
Infection cycle
Though some studies have found "no definitive evidence of transmission by a tick to a vertebrate host," Bartonella species are well-known to be transmissible to both animals and humans through various other vectors, such as fleas, lice, and sand flies. Bartonella bacteria are associated with cat-scratch disease, but a study in 2010 concluded, "Clinicians should be aware that ... a history of an animal scratch or bite is not necessary for disease transmission." All current Bartonella species identified in canines are human pathogens.
SUMMARY
Bartonella is a type of bacteria that can make people very sick. There are three main kinds that cause most of the infections: B. henselae, B. quintana, and B. bacilliformis.
Some of these bacteria are found all over the world (like B. henselae), but others only live in certain places (like B. bacilliformis).
People can catch Bartonella in different ways:
-
B. henselae – usually from a cat scratch or bite.
-
B. quintana – spread by body lice.
-
B. bacilliformis – spread by sand flies.
Once the bacteria get into the body, they infect red blood cells and cause the blood vessels to grow abnormally. This can lead to symptoms like long-lasting fever, swollen lymph nodes, and enlarged liver or spleen.
Doctors figure out if someone has Bartonella using lab tests. They might grow the bacteria in a culture, look for antibodies in the blood (serology), or look at tissues under a microscope. Special tests called PCR can find Bartonella DNA in blood or tissue samples, including heart valves.
Treatment usually involves antibiotics, but the exact medicine depends on which type of Bartonella you have and how sick you are. In some cases, like with cat-scratch disease, a doctor may need to use a needle to drain swollen lymph nodes.
