Pulmonary Arterial Hypertension: Unraveling Its Impact On Heart And Lungs
Conclusion Navigating the complexities of Pulmonary Arterial Hypertension (PAH) might seem daunting. However, with the right knowledge and proactive approach, it’s possible to manage the condition and maintain a good quality of life. PAH, a unique type of high blood pressure affecting the arteries in the lungs, can put extra strain on the heart. Over time, this can lead to heart failure. The condition’s root cause may vary, from genetic factors to other health issues like heart defects, liver disease, or autoimmune diseases. Remember, sometimes the cause remains unknown, resulting in idiopathic pulmonary ...

Conclusion Use of the Khavinson peptides and melatonin in combination in this way, at this dose, negatively impacts the thymus, producing a reduction in active tissue and increase in atrophy to fatty tissue. The degree to which this atrophy occurred is greater than one would expect to take place over nine months of aging at this stage of life. Why did this outcome occur, given the animal studies showing thymic regrowth, and the studies showing reduced later life mortality following use of thymogen? We can only speculate. Firstly, the dose makes the poison, and the dosing here may have been too high, too frequ...

In conclusion, a number of high-income countries, changes in health expectancies over time have not kept pace with the growth in life expectancy. That is, people are living longer but disability and poor health are occupying an increasing proportion of later life. Our findings suggest that countries still need to make significant progress to achieve the WHO's Decade of Healthy Ageing goal of healthier, longer lives for all.

In conclusion, it remains unclear if brain-specific regional and temporal changes occur in the expression of the different APP variants during AD progression. Since APP is also found in blood cells, assessing the changes in APP mRNA expression in peripheral blood cells from AD patients has been considering an alternative. However, again the quantification of APP mRNA in peripheral blood cells has generated controversial results. Brain APP protein has been analyzed in only a few studies, probably as it is difficult to interpret the complex pattern of APP variants and fragments. We previously characterized the soluabl...

The Story of an American Mask Distributor
By SAURABH JHA Seven weeks before President Trump declared COVID-19 a federal emergency heralding the economic lockdown, Jesse’s customers began cutting their orders. Jesse sells garments and cotton, imported predominantly from India, to wholesalers and retailers, big and small, in malls across the North East corridor.  His business had a good January. December was like any December. But February was different.  His customers, reassuring him that it wasn’t personal, were predicting a falling demand for their products because of COVID-19. They may be over reacting, but better shortage than glut, they felt. J...

I Joined Twitter to Teach
I joined Twitter to teach. In May 2016, I started tweeting “questions of the day” for my inpatient hospital medicine team at Thomas Jefferson University Hospital from @RJmdphilly. #GreenQOD (“Green” is our teaching service, and “QOD” for question of the day) was born in the days of only 140 characters per tweet (now expanded to 280), which placed a potentially daunting onus on brevity in phrasing—and answering—clinical questions. My inaugural question? “What’s the real story with beta blockers in reactive airway disease? If increase risk is real, how do you balance risk/benefit?” Rules of t...

What ’s a diagnosis about? COVID-19 and beyond
By MICHEL ACCAD Last month marked the 400th anniversary of the birth of John Graunt, commonly regarded as the father of epidemiology.  His major published work, Natural and Political Observations Made upon the Bills of Mortality, called attention to the death statistics published weekly in London beginning in the late 16th century.  Graunt was skeptical of how causes of death were ascribed, especially in times of plagues.  Evidently, 400 years of scientific advances have done little to lessen his doubts!  A few days ago, Fox News reported that Colorado governor Jared Polis had “pushed back against recen...

The objective is to start treating chronic diseases from the root and not the symptoms of the disease. As we are starting to enroll patients in "senolytics-clinical trials," it will be imperative to assess if senolysis efficiently targets the primary cause of disease or if it works best in combination with other drugs. Additional basic science research is required to address the fundamental role of senescent cells, especially in the established contexts of disease.

The (Sober) State of Artificial Intelligence in the Fight Against COVID-19
If you ask us at The Medical Futurist about the importance of artificial intelligence in healthcare, we will have a lot to talk about. We’ve seen how it could solve alarm fatigue in hospitals. We’ve analyzed the unusual associations the technology discovered in medicine. We believe it will usher the real era of the Art of Medicine. Dr. Meskó even embarked on a journey to better understand the language of A.I. So of course, with the COVID-19 pandemic, we had to explore the contribution of A.I. in this public health crisis. We came across promising endeavours involving such algorithms from mining for insights through...

False Negative: Testing ’s Catch-22
By SAURABH JHA, MD In a physician WhatsApp group, a doctor posted he had fever of 101° F and muscle ache, gently confessing that it felt like his typical “man flu” which heals with rest and scotch. Nevertheless, he worried that he had coronavirus. When the reverse transcription polymerase chain reaction (RT-PCR) for the virus on his nasal swab came back negative, he jubilantly announced his relief.  Like Twitter, in WhatsApp emotions quickly outstrip facts. After he received a flurry of cheerful emojis, I ruined the party, advising that despite the negative test he assume he’s infected and quarantine for ...

Can AI diagnose COVID-19 on CT scans? Can humans?
Vidur Mahajan Vasanth Venugopal By VASANTH VENUGOPAL MD and VIDUR MAHAJAN MBBS, MBA What can Artificial Intelligence (AI) do? AI can, simply put, do two things – one, it can do what humans can do. These are tasks like looking at CCTV cameras, detecting faces of people, or in this case, read CT scans and identify ‘findings’ of pneumonia that radiologists can otherwise also find – just that this happens automatically and fast. Two, AI can do things that humans can’t do – like telling you the exact time it would take you to go from point A to point B (i.e. Google maps), or like in this case, diagnose C...

The ACR Encourages Limiting CT and CXR for COVID-19 Patients
The American College of Radiology (ACR) is urging radiologists to steer clear of CT scans and chest radiographs (CXR) as their first line of diagnostic defense of COVID-19 diagnosis and treatment, according to a recently issued statement. With the unpredictability of available testing kits and early reports of test sensitivity from China, health care providers are turning to imaging devices to detect infection symptoms. However, the ACR encourages healthcare providers to stick to viral testing, and explains why CT and CXR should be used at a minimum. Here are some takeaways from the official recommendation:The results from...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...
