How can Warfarin be safe “ even in ” first trimester of pregnancy ? The story behind the 5 mg cut-off !
The well known pro-coagulant state of pregnancy is an evolutionary protective process to make blood clot quicker, to save fetal loss in early pregnancy and mitigate postpartum bleeding. Still, in many women, this natural adaptive process confers an enhanced thrombotic risk. The molecular mechanisms for this pro-coagulant state are, there is increased factor VII, fibrinogen, reduced protein S. It is interesting to note, while plasminogen levels are elevated, D-dimer is also increased, indicating an ongoing fight between pro & anticoagulant forces, converting the physiological maternal- placental bed a mini harmless DIC ...

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 ...

In this study, we investigated the effect of NXP032 on neurovascular stabilization through the changes of PECAM-1, PDGFR-β, ZO-1, laminin, and glial cells involved in maintaining the integrity of the blood-brain barrier (BBB) in aged mice. NXP032 was orally administered daily for 8 weeks. Compared to young mice and NXP032-treated mice, 20-month-old mice displayed cognitive impairments in Y-maze and passive avoidance tests. NXP032 treatment contributed to reducing the BBB damage by attenuating the fragmentation of microvessels and reducing PDGFR-β, ZO-1, and laminin expression, thereby mitigating astrocytes and microglia ...

Senescent Cells Appear Involved in Graft-Versus-Host Disease
Now that increasing attention is given to senescent cells in the biology of aging, their involvement in a wide range of conditions has been uncovered. The transient creation of senescent cells is a part of wound healing, a process that is harmed by the growing burden of lingering senescent cells that occurs with advancing age, and the inability of the aged immune system to remove these cells in a timely fashion. Given the role in wound healing, is perhaps not surprising to find senescent cells involved in graft-versus-host disease following surgical transplantation of tissue. Senolytic therapies may prove to be useful here...

The Med List: ACE Inhibitors
Today I’m starting a new series called The Med List. Once or twice a month, I’d like take a closer look at a single class of home medications and explore the medical implications for our patients who take these meds. The patient’s medications list holds a wealth of information. Prescribed medications tell us about the patient’s medical history. They also give us clues to the patient’s possible current condition and presentation. Some medicines can better explain the clinical picture in front of us and others can be red flags regarding treatment options and the patients likely response. Let’s kic...

What is carbon dioxide angiography? Cardiology Basics
Carbon dioxide angiography is done using carbon dioxide injection into the blood vessel. Usually iodine containing radiocontrast dyes  are injected into the blood vessels and continuous X-ray imaging done, to obtain angiograms. Contrast material is needed to visualize the blood vessel separately from the other body tissue. But usual iodinated radiocontrast dyes have a potential risk of causing acute kidney injury. This is more so in those with already impaired renal function. It is in this situation that carbon dioxide angiography is usually considered. Usual angiograms appear dark while carbon dioxide angiogram look...

Fight Aging! Newsletter, May 2nd 2022
In this study, we tested the therapeutic potential of VHHASC and a newly generated VHH against murine ASC (VHHmASC) to target ASC specks in vitro and in vivo. We show that pre-incubation of extracellular ASC specks with VHHASC abrogated their inflammatory functions in vitro. Recombinant VHHASC rapidly disassembled pre-formed ASC specks and thus inhibited their ability to seed the nucleation of soluble ASC. Notably, VHHASC required prior cytosolic access to prevent inflammasome activation within cells, but it was effective against extracellular ASC specks released following caspase-1-dependent loss of membrane integrity, an...

Towards Control of Inflammation as an Important Goal in the Treatment of Aging
Today I'll point out a review article that laments the present state of progress towards the control of inflammation in the human body. While acknowledging that great strides have been made in ways to interfere in inflammatory signaling, benefiting many patients, present tools are crude in comparison to the technologies that will most likely be needed in order to truly control unresolved, chronic inflammation and eliminate its contribution to age-related disease. True control of inflammation would imply the ability to (a) trigger resolution mechanisms with specificity, avoiding impairment of the operation of inflammation w...

This is Not Health Care
By HANS DUVEFELT We use the word health rather loosely in America today. Especially the expression health care, whether you spell that as one word or two, is almost an oxymoron. Health is not simply the absence of disease, even less the pharmaceutical management of disease. The healthcare “industry” is not the major portion of our GNP that it is because there is a lot of health out there, but the opposite. What consumes so much money and generates so much profit is, of course, sick care. The sicker people are, the more money is spent and earned in this market segment. It is a spiral, and a vicious one. Hea...

Autoimmune lung disease: Early recognition and treatment helps
A man who was diagnosed with rheumatoid arthritis (RA) five years ago sees his rheumatologist for a follow-up visit. Fortunately, his arthritis is well controlled through medication. He can walk and do all his daily activities without pain. But over the past six months, he’s been feeling short of breath when climbing stairs. He has an annoying dry cough, too. COVID-19? That’s ruled out quickly. But a CT scan of his chest reveals early fibrosis (scarring) of the lungs, most likely related to rheumatoid arthritis. “I can finally walk normally, and now I can’t breathe when I walk!” says the frustrated patient, whose...

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

Age-Slowing Interventions in the Context of Lung Aging
Researchers here consider a very conservative set of interventions known to modestly slow the progression of aging in laboratory species, largely by altering metabolism to upregulate beneficial cellular stress responses. The researchers look through the lens of lung aging, specifically, reviewing the evidence for these therapies to slow the deterioration in lung function and onset of lung disease in older individuals, or to be the basis for treating established lung disease. To date, the most reliable, best-researched way to extend life span is through the practice of calorie restriction (CR), which involves reduc...

Senolytic Treatment with Dasatinib and Quercetin Confirmed to Reduce the Burden of Senescent Cells in Human Patients
Setting aside the mice genetically engineered to destroy senescent cells, the combination of dasatinib and quercetin is the oldest of the senolytic treatments used in animal studies. Senolytic therapies are those that selectively destroy senescent cells in old tissues in order to produce rejuvenation, turning back the progression of numerous age-related conditions. Unusually for early stage research, these initial senolytics are actually quite effective, considered in the grand scheme of things. Thus they have moved directly to human trials in some cases. The first data on their ability to produce the same outcomes in huma...
