Study: “Anti-Inflamatory” Diet Of Vegetables, Fruits, Coffee & Tea Lowers Heart Disease And Stroke Risks

Dietary patterns with a higher proinflammatory potential were associated with higher CVD risk. Reducing the inflammatory potential of the diet may potentially provide an effective strategy for CVD prevention.

Background

Inflammation plays an important role in cardiovascular disease (CVD) development. Diet modulates inflammation; however, it remains unknown whether dietary patterns with higher inflammatory potential are associated with long-term CVD risk.

Healthy Longevity: ‘The Science Of Aging’ (Salk Institute Video)

“Aging is such a profound part of not only the human experience but all life on Earth,” says Salk Vice President/Chief Science Officer Martin Hetzer. “It’s one of the big, untapped opportunities in biomedical research, particularly around questions on what role exercise, nutrition and cognitive stimulation play in staying healthy throughout life. It is important not to forget that getting older also comes with benefits; we want to take a holistic view of human health at all ages and understand it from all angles.”

Scientists want to answer intriguing questions: Why are some people able to “age well,” trekking up mountain ranges or rafting through white water in their nineties, while others live just as long, disease-free, but grow inexplicably frail decades sooner? Worse yet, why does advanced age sometimes diminish cognitive ability or even lead to dementia?

In numerous diseases, age itself is the major risk factor. Cancer, Alzheimer’s, heart disease and many other afflictions become profoundly more likely the older we get. Aside from extending our life spans, scientists want to know how we can also extend our health during advanced age. What is emerging from research is that aging–loosely defined as a systems-wide deterioration of our cells, organs and genetic material that results in disease or damage–is a collective and complex process in the body.

Health Studies: 80% Of Married Couples Share Heart Disease Risks, Poor Health Lifestyles (JAMA)

OCTOBER 26, 2020

In this cross-sectional study of 5364 couples consisting of employees and spouses (or domestic partners) undergoing an annual employer-sponsored health assessment, 79% of the couples were in the nonideal category of a CV health score. This within-couple concordance of nonideal CV health scores was associated mostly with unhealthy diet and inadequate physical activity.

The study included 10 728 participants (5364 couples): 7% were African American, 11% Hispanic, 21% Asian, and 54% White (median [interquartile range] age, 50 [41-57] years for men and 47 [39-55] for women). For most couples, both members were in the ideal category or both were in a nonideal category.

Concordance ranged from 53% (95% CI, 52%-54%) for cholesterol to 95% (95% CI, 94%-95%) for diet. For the CV health score, in 79% (95% CI, 78%-80%) of couples both members were in a nonideal category, which was associated mainly with unhealthy diet (94% [95% CI, 93%-94%] of couples) and inadequate exercise (53% [95% CI, 52%-55%] of couples). However, in most couples, both members were in the ideal category for smoking status (60% [95% CI, 59%-61%] of couples) and glucose (56% [95% CI, 55%-58%]).

Except for total cholesterol, when 1 member of a couple was in the ideal category, the other member was likely also to be in the ideal category: the adjusted odds ratios for also being in the ideal category ranged from 1.3 (95% CI, 1.1-1.5; P ≤ .001) for blood pressure to 10.6 (95% CI, 7.4-15.3; P ≤ .001) for diet. Concordance differed by ethnicity, socioeconomic status, and geographic location.

Studies: Osteoarthritis Patients Using Exercise Therapy Have Less Pain, Cut Opioid & Analgesic Use

Conclusion Among patients with knee or hip OA using analgesics, more than half either discontinued analgesic use or shifted to lower risk analgesics following an 8-week structured exercise therapy and patient education programme (GLA:D). These data encourage randomised controlled trial evaluation of whether supervised exercise therapy, combined with patient education, can reduce analgesic use, including opioids, among patients with knee and hip OA pain.

Covid-19 Studies: 77% Of Hospitalized Patients Are Overweight Or Obese

SEPTEMBER 11, 2020

But on its own, “BMI [body mass index] remains a strong independent risk factor” for severe COVID-19, according to several studies that adjusted for age, sex, social class, diabetes, and heart conditions, says Naveed Sattar, an expert in cardiometabolic disease at the University of Glasgow. “And it seems to be a linear line, straight up.”

  • For starters, the blood of people with obesity has an increased tendency to clot—an especially grave risk during an infection that, when severe, independently peppers the small vessels of the lungs with clots 
  • Immunity also weakens in people with obesity, in part because fat cells infiltrate the organs where immune cells are produced and stored, such as the spleen, bone marrow, and thymus, says Catherine Andersen, a nutritional scientist at Fairfield University. “We are losing immune tissue in exchange for adipose tissue, making the immune system less effective in either protecting the body from pathogens or responding to a vaccine,” she says.

The impact extends to the 32% of people in the United States who are overweight. The largest descriptive study yet of hospitalized U.S. COVID-19 patients, posted as a preprint last month by Genentech researchers, found that 77% of nearly 17,000 patients hospitalized with COVID-19 were overweight (29%) or obese (48%). (The Centers for Disease Control and Prevention defines overweight as having a BMI of 25 to 29.9 kilograms per square meter, and obesity as a BMI of 30 or greater.)

Studies: “Insomnia / Short Sleep Duration” Is A Type 2 Diabetes “Risk Factor”

Diabetologia  (Sept 8, 2020) – Insomnia with objective short sleep duration has been associated with an increased risk of type 2 diabetes in observational studies [2728]. The present MR study found strong and suggestive evidence of a causal association of insomnia and short sleep duration, respectively, with increased risk of type 2 diabetes.

Conclusions/interpretation

The present study verified several previously reported risk factors and identified novel potential risk factors for type 2 diabetes. Prevention strategies for type 2 diabetes should be considered from multiple perspectives on obesity, mental health, sleep quality, education level, birthweight and smoking.

Health: “Compression Therapy” Reduces Chronic Cellulitis & Leg Edema

New England Journal of Medicine (Aug 13, 2020) – In this small, single-center, nonblinded trial involving patients with chronic edema of the leg and cellulitis, compression therapy resulted in a lower incidence of recurrence of cellulitis than conservative treatment.

The researchers have conducted a single-center, randomized, nonblinded trial that aimed to find out an association between the compression therapy and controlled incidents of chronic edema of the leg and people with cellulitis that can be defined as an infection of the skin that involves subcutaneous tissues or the innermost layer of the skin. Cellulitis can be caused by trauma or scratching of other lesions due to animal or human bites that result in fever, extreme pain, and redness of the skin.

Studies: 4- And 6-Hour Time-Restricted Eating (TRE) Diets, No Food Limits Result In Weight Loss

UIC Chicago Illinois
University of Illinois, Chicago (July 15, 2020)

“The findings of this study are promising and reinforce what we’ve seen in other studies — fasting diets are a viable option for people who want to lose weight, especially for people who do not want to count calories or find other diets to be fatiguing,” Varady said. 

…participants in both daily fasting groups reduced calorie intake by about 550 calories each day simply by adhering to the schedule and lost about 3% of their body weight. The researchers also found that insulin resistance and oxidative stress levels were reduced among participants in the study groups when compared with the control group.

4- And 6-Hour Time Restricted Eating TRE DietsTwo daily fasting diets, also known as time-restricted feeding diets, are effective for weight loss, according to a new study published by researchers from the University of Illinois at Chicago.

The study reported results from a clinical trial that compared a 4-hour time-restricted feeding diet and a 6-hour time-restricted feeding diet to a control group.

“This is the first human clinical trial to compare the effects of two popular forms of time-restricted feeding on body weight and cardiometabolic risk factors,” said Krista Varady, professor of nutrition at the UIC College of Applied Health Sciences and corresponding author of the story.
