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 ...

Surgical Patch Alerts to Intestinal Leaks
Scientists at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have developed an advanced surgical sealant that can alert clinicians to the presence of an intestinal leak after gastrointestinal surgery. Such leaks can be very dangerous, but until now clinicians had few ways to detect them before they start causing symptoms. This new polymer patch reacts to pH changes in the presence of leaked intestinal fluid, and produces small bubbles within its structure in response, often within minutes or hours of a leak starting. This physical change in the patch can be visualized using ultrasound or CT scan...

The inspirational journey of an 82-year-old WWII veteran battling cancer
He was 82 years old when he came into our ER, writhing in excruciating abdominal pain. After an ultrasound and a subsequent CT scan, the devastating diagnosis was revealed—end stage pancreatic and liver cancer. Despite enduring a pain level of 10, he managed to maintain his sense of humor, joking about “biting the bullet.” However,

Age-Related Dysfunction of Water Homeostasis
https://www.fightaging.org/archives/2023/06/age-related-dysfunction-of-water-homeostasis/
Dehydration can be an issue in older people. As in every complex system in the body, the mechanisms by which hydration is regulated become dysfunctional with advancing age. Researchers here look at the brain region responsible for regulating some of the response to dehydration, cataloging altered gene expression in search of the more important mechan...

Myocardial Insulin Resistance
Myocardial insulin resistance is said to occur in about 60% of patients with type 2 diabestes mellitus and is associated with higher cardiovascular risk compared to those with insulin sensitive myocardium [1]. It is known that systemic insulin resistance is an independent risk factor for heart failure and cardiovascular death [2]. Myocardial insulin resistance occuring along with systemic insulin resistance is characterized by ineffecient energy metabolism and contributes to post ischemic heart failure. Myocardial insulin resistance can also be caused by myocardial hypertrophy, independent of systemic insulin resist...

Smart Sutures Sense Inflammation, Deliver Drugs, Cells
Researchers at MIT have developed smart sutures with a hydrogel coating that contains sensing and drug delivery components, and could even be used to implant therapeutic cells. The sutures are made using pig tissues that have been decellularized with detergents to reduce the possibility that they could provoke an immune reaction. The surrounding hydrogel layer contains microparticles that can release peptides when enzymes involved in inflammation are present, and other microparticles that allow for controlled release of drugs. Another potential cargo is therapeutic stem cells that can assist with tissue repair. So far, the...

The Future of Telemedicine Transformed by Large Language Models
Conclusion
Integrating AI, particularly large language models, into telemedicine holds immense potential for transforming healthcare delivery and improving patient outcomes. By acknowledging and navigating the associated risks and challenges, AI-driven telehealth solutions can lead to a more accessible, efficient, and personalized healthcare experience.
As we continue to improve and develop and refine these technologies, it is crucial to maintain a strong focus on ethical considerations and inclusivity to ensure a future of equitable and responsible AI-driven telehealth services. (Source: EMR and HIPAA)

A 30-something woman with intermittent CP, a HEART score of 2 and a Negative CT Coronary Angiogram on the same day
This was sent by a colleague.A 34 yo woman with a history of HTN, h/o SVT s/p ablation 2006, and 5 months post-partum presented with intermittent central chest pain and SOB. She had one episode of pain the previous night and two additional episodes early on morning the morning she presented. Deep breaths are painful and symptoms come and go. She had one BP that was measured at 160/120, uncertain when and what the BP was at other moments. Home meds were labetalol and nifedipine. There are T-wave inversions in precordial leads. The patient is pain free, so it is qu...

The Hidden Barrier to Better Healthcare
The following is a guest article by Josh Miller, Co-Founder & CEO at Gradient Health.
As a global society, we have never spent more on healthcare. We have never been more informed. We’ve never been more advanced. Yet there is a great divide between what we have accomplished scientifically, and what patients actually get access to.
This is not something spoken about a lot, because the focus is of course on developing life-saving medical devices and diagnostics. However, despite new innovations being created, funded, and announced every week, the speed with which these new technologies are being adopted is slow if they...

6 Healthcare Examples Of Virtual, Augmented And Mixed Reality
Lately, there has been a tendency in the tech world to adopt “new” realities in their midst. Meta has a branch dedicated to developing virtual reality (VR) hardware and software; earlier this year HTC unveiled its new augmented reality (AR) glasses; while Apple is reportedly gearing up to launch a mixed reality (MR) headset.
Collectively, VR, AR and MR fall under the umbrella term of extended reality (XR), which analysts believe holds the potential to be the next major computing platform. Such potentials have spillover effects into the medical field through digital health approaches, and healthcare practice is...

Don ’ t neglect the power of clinical examinations in modern medicine
I intended to write an essay endorsing the clinical examination (CE), but recent personal events have made me reconsider. I had outpatient sinus surgery and developed chest pain the next day, leading me to my local rural hospital’s emergency department (ED). The ED physician diagnosed atrial fibrillation, and a CT scan revealed a small pulmonary

Antibacterial Smart Sutures Visible in CT Scans
Researchers at RMIT University in Australia have developed ‘smart stitches’ that can fight bacteria and reveal the location of the sutured area in CT scans. The sutures have been developed to reduce the chances of surgical site infections and also make life a little easier for clinicians, as the material shows up in CT scans, allowing for identification of the location of the sutures in the body and quick assessment if they are performing as required. In particular, the researchers envisage the sutures as a replacement for vaginal meshes that are used to treat prolapses, for which surgical site infection rates tend to ...

Regional wall motion abnormalities in LAD territory on echocardiography.
Echocardiography is one of the simplest investigations to assess the myocardial regional wall motion abnormalities in coronary artery disease. Regional wall motion abnormalities can also be assessed by nuclear imaging and cine CT (computed tomography) scan / MRI (magnetic resonance imaging). The wall motion is scored from 1 to 4 depending on whether it is normal wall motion, hypokinesia, akinesia or dyskinesia. Hypokinesia means reduced contraction, akinesia means absence of contraction and dyskinesia means bulging out in systole. In order to standardize the reporting of wall motion abnormalities, American Society of Echo...
