In conclusion, our study demonstrated that elevated cumulative SBP or DBP was independently associated with increased risk of CVD in the Chinese population. Among participants with 15-year cumulative BP levels higher than the median, that is, 1970.8/1239.9 mmHg-year for cumulative SBP/DBP, which was equivalent to maintaining SBP/DBP level higher than 131/83 mmHg in 15 years, the CVD risk would increase significantly irrespective of whether or not the BP measurements at one examination was high. Our findings emphasize the importance of cumulative BP level in identifying individuals with high risk of CVD in the future. ...

Cardiology MCQs
Modified Blalock-Taussig shunt is: End to side anastomosis of subclavian artery to a pulmonary artery Side to side anastomosis of main pulmonary artery to aorta Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit Anastomosis of superior vena cava to right pulmonary artery Correct answer: 3. Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit In classic Blalock-Taussig shunt, the subclavian artery is divided and anastomosed to the pulmonary artery as an end to side anastomosis. In modified Blalock – Taussig shunt, a Gore – Tex graft is used to connect th...

How Big Pharma Bought Big Media for  $6 Billion: The Unintended Consequences of Direct-to-Consumer Drug Advertising
Media, whether broadcast, streamed, or print, is a lifeline of information for most Americans. Updates on the pandemic, results of an election, knowing whether you are in the path of an oncoming hurricane or snowstorm—we are alerted by news reports and thereby dependent on the factual information they provide. Media informs, shapes opinions, keeps us out of harm’s way. Despite the public pummeling media has received over the past few years, media remains the means through which Americans view much of their world. What the media reports—or does not report—is therefore crucial to shaping opinion and behavior.  There...

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.

Progress on Understanding Why Human Growth Hormone Receptor Variants are Associated with Greater Longevity
A few years back, researchers noted that a common growth hormone receptor gene variant was associated with greater life expectancy in humans. There was some theorizing as to possible mechanisms at the time, following the usual paths for anything that touches on growth hormone or its receptor. In short-lived mammals such as mice, loss of function in growth hormone or its receptor produces small body size and increased healthy longevity. The present record for mouse longevity is held by a growth hormone receptor knockout lineage. In humans, members of the small Laron syndrome population exhibit an analogous disruption of gro...

In conclusion, iMSC-sEVs could rejuvenate the senescence of NPCs and attenuate the development of IVDD. Cell Signaling via Exosomes in the Development of Vascular Calcification https://www.fightaging.org/archives/2021/05/cell-signaling-via-exosomes-in-the-development-of-vascular-calcification/ Vascular calcification is a feature of aging, a process in which cells in the blood vessel wall take on inappropriate identities and activities that are more appropriate to bone tissue. Evidence of recent years implicates chronic inflammation and the presence of senescent cells in this process. Senescent cells caus...

In conclusion, we showed that addition of resistance exercise training, but not dietary EAAs, to the myostatin inhibition further increased muscle mass through the attenuation of muscle protein breakdown with proportionate improvements in muscle strength. Interestingly, addition of dietary EAAs to the myostatin inhibition with or without resistance exercise training improved muscle quality. Thus, dissection of the underlying mechanisms behind the combined positive effect of dietary EAAs and resistance exercise training on muscle mass and quality can shed light on the discovery of effective therapeutics against muscle wasti...

This study is consistent with previous evidence showing that inflammaging, or age-related inflammation, is naturally heightened in the nervous system. Moreover, the authors disproved their hypothesis that anti-inflammatory microglia-specific genes are responsible for the elevated inflammatory response in aged brains since the expression of anti-inflammatory mediators was elevated in middle-aged brains following infection. Thus, the cause for the increase in pro-inflammatory genes remains to be elucidated. Mixed Results in Animal Studies of Gene Therapy Targeting Axonal Regrowth https://www.fightaging.org/archiv...

This study suggests that some of those changes contribute to age-related hypertension, providing yet another reason to put resources into the near term development of therapies that can reverse the aging of the gut microbiome, such as flagellin vaccination or fecal microbiota transplantation. "Previous studies from our lab have shown that the composition of the gut microbiota in animal models of hypertension, such as the SHRSP (spontaneously hypertensive stroke-prone) rat model, is different from that in animals with normal blood pressure. Further, transplanting dysbiotic gut microbiota from a hypertensive animal ...

VITAL trial on vitamin D
Role of vitamin D in cardiovascular disease has been suggested by observational studies. Low blood levels of vitamin D was found to be associated with higher risks of heart disease, stroke, hypertension and diabetes mellitus [1]. But the 2011 Institute of Medicine (United States) guidance concluded that the evidence is inconsistent and inconclusive, not meeting the criteria for a cause effect relationship [2]. VITAL study was a randomized placebo controlled trial of vitamin D3 (cholecalciferol) at a dose of 2000 IU per day and omega-3 fatty acids at a dose of 1 g per day for prevention of cancer and cardiovascular diseas...

In conclusion, the MR exhibited the protective effects against age-related behavioral disorders, which could be partly explained by activating circulating FGF21 and promoting mitochondrial biogenesis, and consequently suppressing the neuroinflammation and oxidative damages. These results demonstrate that FGF21 can be used as a potential nutritional factor in dietary restriction-based strategies for improving cognition associated with neurodegeneration disorders.

Women, alcohol, and COVID-19
Excessive alcohol use is a common response to coping with stress. Alcohol use increased following the September 11th terrorist attacks and Hurricanes Katrina and Rita. The COVID-19 pandemic is following this same path. However, this pandemic is different in its scope and duration. COVID-19 is associated with both negative health and economic impacts, as well as grief, loss, and prolonged stress and uncertainty. The emotional impact of COVID-19 on women According to the U.S. National Pandemic Emotional Impact Report, compared to men, women reported higher rates of pandemic-related changes in productivity, sleep, mood, healt...
