HDAC Inhibition Suppresses the Senescence-Associated Secretory Phenotype
The research materials here cover the recent work of one of many groups digging deeper in the mechanisms of cellular senescence, in search of novel ways to make senescent cells less harmful to surrounding tissues, or means to selectively destroy them outright. The accumulation of senescent cells with age is now well proven to contribute to aging, generating chronic inflammation and disrupting tissue function via a potent mix of signals known as the senescence-associated secretory phenotype, or SASP. The scientists involved here have discovered that HDAC inhibitors can to some degree suppress the SASP, and this intervention...

In conclusion, the recently demonstrated protective effects of NMN treatment on neurovascular function can be attributed to multifaceted sirtuin-mediated anti-aging changes in the neurovascular transcriptome. Our present findings taken together with the results of recent studies using mitochondria-targeted interventions suggest that mitochondrial rejuvenation is a critical mechanism to restore neurovascular health and improve cerebral blood flow in aging.

The role of our minds in the avoidance of falls
A few years ago, my grandmother suffered a fall and broke her hip. She has never fully recovered and is now constantly fearful of falling, and has significantly limited her activities to prevent a fall from ever happening again. As a scientist focused on translational research in mobility and falls in older adults, of course I asked her how she fell. She stated that she was standing in the kitchen and reading a recipe when the phone rang. When she turned and started to walk over to the phone, her feet “weren’t in the right spot.” She fell sideways and unfortunately, her hip was unable to absorb the impact without bre...

Embolic stroke of undetermined source (ESUS)
Cryptogenic Stroke/ESUS International Working Group defined embolic stroke of undetermined source (ESUS) as a non-lacunar brain infarct without proximal arterial stenosis or cardioembolic sources, with a clear indication for anticoagulation [1]. They presumed that as emboli are more likely to be thrombi, recurrence may be better prevented by anticoagulation rather than antiplatelet agents. Randomized trials with directly acting oral anticoagulants were suggested to test this hypothesis.
But two randomised trials testing this aspect, NAVIGATE ESUS (Rivaroxaban Versus Aspirin in Secondary Prevention of Stroke and Prevention...

Five healthy habits net more healthy years
Are healthy habits worth cultivating? A recent study suggests healthy habits may help people tack on years of life and sidestep serious illnesses, such as diabetes and cancer. After all, if you’re going to gain an extra decade of life on this earth, you want to enjoy it!
What did this research focus on?
Researchers from the Harvard T.H. Chan School of Public Health looked at data from more than 73,000 women enrolled in the Nurses’ Health Study (NHS) who were followed for 34 years, and more than 38,000 men enrolled in the Health Professionals Follow-up Study (HPFS) who were followed for 28 years.
In a previous study usi...

Good news for those with type 2 diabetes: Healthy lifestyle matters
Type 2 diabetes (T2D) is a metabolic disorder of insulin resistance — a reduced sensitivity to the action of insulin — which leads to high blood sugar, or hyperglycemia. Approximately 12% of American adults have T2D, and more than one-third of Americans have prediabetes, a precursor to T2D. This is a major public health concern, as T2D dramatically increases risk for heart disease, including heart attacks, atrial fibrillation, and heart failure.
The development and progression of T2D is affected by many factors. Some, such as a person’s race/ethnicity, age, and gender cannot be modified. Others, including body weight...

In conclusion, the concept of an epigenetic clock is compelling, but caution should be taken in interpreting associations with age acceleration. Association tests of age acceleration should include age as a covariate.

In conclusion, this study suggests that epigenetic age acceleration is significantly associated with lung function in women older than 50 years. We hypothesised that this could be due to menopause. However, we have observed that menopause has minimal effect and therefore there is possibility of other unknown physiological factors at older age in females mediating the epigenetic age acceleration effect on lung function. While, it is still unknown what exactly epigenetic aging from DNA methylation measures, this study suggests it can be utilised as one of the important factors to assess women's lung health in old age. DNA me...

Are you getting enough sleep … or too much? Sleep and stroke risk
This study found an association between stroke risk and longer sleep, longer midday napping, or poor sleep quality. But an association is not the same as causation. Rather than longer sleep duration causing strokes, there are other possible explanations for the findings. For example, people who sleep more at night or nap more during the day may have other risk factors for stroke, such as:
A higher incidence of depression. Excessive sleeping or poor sleep quality may be symptoms of depression, and prior studies have noted higher stroke rates among depressed individuals.
A more sedentary lifestyle. Those who are not active ...

Premature Menopause Correlates with Greater Later Incidence of Chronic Disease
Undergoing earlier menopause is a sign of a greater burden of age-related damage and dysfunction, so it should not be surprising to see that this correlates with a greater incidence of chronic disease in the years thereafter. People with a greater burden of cell and tissue damage tend to exhibit all of the manifestations of aging earlier than their less damaged peers. These variations in damage burden and consequences from individual to individual are near all the results of lifestyle choices, particularly smoking, weight, and exercise, and environmental factors such as exposure to chronic viral infection. Genetics plays o...

LDL cholesterol: How low can you (safely) go?
In this study, there was no increased risk of adverse outcomes (including muscle aches, liver dysfunction, new onset of diabetes, cancer, and bleeding strokes), even when LDL was lowered to as low as 20 mg/dL. Although statin medications themselves have been linked to side effects, especially at high doses, it appears that extremely low LDL concentrations are not responsible for side effects.
In other words, lowering LDL beyond our previous target of 70 mg/dL appears to be not only safe but beneficial, in patients with CVD.

Long-Term Effect of Binge Drinking on the Body
Most people know about the damaging effects that binge drinking can bring to someone’s life. Loss of enjoyment of life, losing family relationships, financial and career struggles, homelessness, and legal consequences are just the tip of the iceberg. However, it can be more difficult to realize the long-term effect of binge drinking on the body, because you cannot always see it. Frequent binge drinking poses many dangerous health risks, and many of them can lead to death.

Menopause and insomnia: Could a low-GI diet help?
Sleep disturbances such as insomnia are extremely common, especially in women after menopause. According to data from the National Institutes of Health, sleep disturbance varies from 16% to 42% before menopause, from 39% to 47% during perimenopause, and from 35% to 60% after menopause.
Insomnia is a serious medical problem defined by frequent difficulty falling or staying asleep that impacts a person’s life in a negative way. Hormone changes around menopause can lead to sleep problems for many reasons, including changing sleep requirements, increased irritability, and hot flashes.
What menopausal women eat could have an ...
