How an Inverted Population Pyramid Affects Society Have you noticed more older adults out and about lately? Maybe you’ve seen an increase in silver-haired shoppers at the grocery store or more seniors enjoying breakfast at your favorite brunch spot. If so, you’re not wrong! The number of older adults is increasing, with nearly one in six people in the United States aged 65 or older. That’s a vast increase from the one in 20 people aged 65 or older just 100 years ago. In some countries, declining birth rates and increased life expectancy have created what’s known as an inverted population pyramid, where older adults outnumber younger generations. But what does this shift mean for society? Let’s explore its implications and how it contrasts with other population structures

Broken Heart Syndrome: Symptoms, Causes and When It Can Be Dangerous Heartbreak is usually thought of as emotional pain. You’re probably familiar with the feeling of discomfort that settles in your chest and feels like it’ll never go away. Most people expect it to fade with time, distractions and a little TLC. But in rare cases, intense emotional or physical stress can affect the heart itself. This condition is known as broken heart syndrome, and despite the poetic name, it’s a real medical diagnosis. What Is Broken Heart Syndrome? Broken heart syndrome, also called stress-induced cardiomyopathy or takotsubo syndrome, is a temporary heart condition triggered by extreme stress. What Are the Symptoms? The symptoms can closely resemble a heart attack, which is why medical evaluation is always important. Common symptoms of broken heart syndrome include: Chest pain Shortness of breath Dizziness Sweating A sudden feeling of weakness or discomfort While these symptoms can feel frightening, broken heart syndrome doesn’t usually cause permanent heart damage when treated promptly. Most people recover fully within weeks or months. Without medical care, however, the heart muscle can weaken, increasing the risk of complications such as heart failure, abnormal heart rhythms or low blood pressure. What Causes Broken Heart Syndrome? Broken heart syndrome is typically caused by a sudden surge of stress hormones, such as adrenaline, which temporarily interfere with the heart’s ability to pump blood effectively. Emotional stressors may include: The loss of a loved one A breakup or major relationship conflict Intense fear, shock or grief In addition, physical stressors like severe injuries or infections can also trigger takotsubo syndrome. Women — particularly post-menopausal women — account for roughly 90% of reported cases, though researchers are still working to understand why. Is Broken Heart Syndrome Dangerous? In most cases, broken heart syndrome is treatable and reversible

How Does the Immune System Fight Pathogens? An Immunophysiology Guide Your immune system is constantly working behind the scenes to protect you from illness. When a pathogen, like a virus or bacteria, enters the body, your immune system recognizes that something doesn’t belong and begins responding to the threat. Some defenses act almost immediately, while others learn to recognize a specific invader and so they can respond faster if it returns. That process is at the heart of immunophysiology, the study of how the immune system functions within the body. Understanding it helps explain why we can fight off some infections quickly, why others keep us in bed for a week (no passing Go, no collecting $200, thank-you-very-much) and how the body can become better prepared for future exposure. So, how does the immune system fight pathogens? Let’s look at what happens once a threat enters the body. What Are Pathogens? Pathogens are microorganisms or other infectious agents that can cause disease

7 Unexpected and Lucrative Careers in Gerontology A major workforce shortage is coming that will immeasurably impact the welfare of our senior citizens. Between 2019 and 2034, the number of Americans aged 65 and older is projected to grow by about 40%, according to the Association of American Medical Colleges (AAMC). During the same period, the AAMC predicts a possible physician shortfall of 124,000. This math is concerning, but it also presents a tremendous opportunity for aspiring gerontologists, geriatricians and other professionals who help older adults. Many of these diverse roles offer the potential of high earnings, and some may surprise you. High-Paying Gerontology Careers Beyond Traditional Roles Careers that promote the well-being of older adults can extend well beyond healthcare roles, including the following examples: Retirement Coach Retiring after a decades-long career can be a major life change, both financially and psychologically. Many soon-to-be retirees can understandably become anxious about the transition.

3 Recent Discoveries in Anatomy Scientists and educators have worked tirelessly for centuries to discover and interpret all of the secrets of human anatomy. We know, for instance, that the body contains 206 bones and approximately 60,000 miles of veins, arteries and capillaries. Yet, thanks to rapid advancements in medical research and technology, new discoveries continue to reveal intricate details about our anatomy, and many breakthroughs are unfolding right before our eyes. Here are examples of recent findings: #1 Protective Barrier in the Brain Scientists at the University of Rochester found a previously unknown compartment in the subarachnoid area of the brain, which acts as the brain’s immune defense system. The layer consists of a thin section between the skull and brain filled with cerebrospinal fluid, and has several responsibilities: Physical protection: Acts as a cushion, protecting the brain from impact. Nutrient and waste transport: Facilitates nutrient delivery and waste removal. Immune surveillance: Enables immune cells to identify and respond to pathogens or abnormal cells. Scientists are optimistic about the impact this newly discovered compartment may play in treating neurological diseases, like multiple sclerosis and Alzheimer’s. Both conditions involve immune dysregulation within the brain, and the hope is that this compartment may play a role in developing targeted therapies that could improve the outlook for both diseases. #2 A New Layer of Muscle in the Jaw Try moving your lower jaw backward, toward your ears
