No Nicotine? No Problem for Vascular Harm 

The study underscores the immediate risks of vaping on vascular health, reinforcing the call to avoid both smoking and vaping.

United States: An imaging study shows that even if the e-cigarettes don’t contain any nicotine, their impact on the blood vessels is immediate. 

Study Overview 

“For years, e-cigarettes have been advertised as a safer form of tobacco smoking,” said Dr. Marianne Nabbout, a resident at the University of Arkansas for Medical Sciences leading a new study to determine the impacts of vaping, with or without nicotine, as reported by HealthDay. 

Key Findings 

A cross-sectional study was carried out at the University of Pennsylvania that involved a total of 31 vapers and smokers of 21-49 yrs.  

Each underwent an MRI twice. They were imaged both before and once after using three types of smoke: Tobacco cigarettes, e-cigarette aerosol with nicotine, and e-cigarettes without nicotine. 

They were given a cuff on their upper thigh to minimize the amount of blood that was supplied to their lower limbs. Once this was deflated, the blood flow rate in the large femoral artery and the percentage of oxygen in the blood that was returned to the heart after providing for the tissues was determined. 

In the process of studying the blood flow, a specific type of MRI named phase-contrast was employed. 

Next, the findings of the researchers were matched with ten non-smoker and non-vaper subjects aged between 21 and 33 years. 

The findings were telling: When exhaling each of the vapes or smokes, the reductions in the blood flow in the femoral artery were equal to those observed in smoking. The major artery of the lower limbs originates from the abdominal aorta and extends to the thigh, carrying oxygenated blood to the entire lower limbs. 

Vein function was found to deteriorate least when using e-cigarettes containing pure nicotine.  

Upcoming Presentation 

The findings will be presented on December 2 at the Radiological Society of North America’s annual meeting in Chicago. 

The researchers also noted that vapers had less oxygen in their blood – implying that there was a reduction in oxygen availability right after vaping. They aim to share the results on December 2 in Chicago during the Radiological Society of North America meeting. 

Expert Advice 

“If the acute consumption of an e-cigarette can have an effect that is immediately manifested at the level of the vessels, it is conceivable that the chronic use can cause vascular disease,” Nabbout said in a meeting news release, as reported by HealthDay. 

Her advice for users? “Refraining from smoking and vaping is always recommended,” she said.

New Discovery: 5 Blood Proteins Could Foreshadow Liver Illness Over a Decade Early 

A study pinpoints five elusive blood proteins that can flag severe liver illness up to 16 years before symptoms strike, offering a chance of prolonged health.

Forecasting ailments long before their grip tightens could shift the medical realm from reactive to preventative. A group of researchers has spotlighted five subtle yet potent blood proteins capable of forewarning an individual’s odds of enduring an advanced liver malady—well over a decade before it manifests. These transformative revelations, slated for unveiling at Digestive Disease Week (DDW) 2025, unlock avenues for swifter detection, swifter actions, and, perhaps, superior outcomes. 

Silent Surge of MASLD 

This research zeroes in on metabolic dysfunction-associated steatotic liver disease (MASLD), a silent epidemic now reigning as the foremost liver disease worldwide. The frequency of MASLD continues to swell, dragging along a fatality risk that towers nearly twofold over those untouched by it. 

Whispers from Within: The Biomarker Breakthrough 

“Picture having foresight into MASLD’s threat long before it stirs,” shared Dr. Shiyi Yu, a resident in gastroenterology at Guangdong Provincial People’s Hospital, China. “Most only recognize liver peril after it clenches tight. There’s a dire craving for reliable biomarkers and forecasting blueprints. Our endeavor uncovers plasma proteins as harbingers of hope,” according to SciTechDaily.com. 

Drilling into over 50,000 blood specimens from the UK Biobank and tracing participants for 16+ years, researchers scrutinized over 2,700 distinct proteins. From this biological sea, five proteins surfaced as early harbingers: CDHR2, FUOM, KRT18, ACY1, and GGT1—biochemical whispers of liver calamity to come. 

Numbers That Speak Volumes 

This protein ensemble demonstrated a startling foresight: an 83.8 percent predictive edge five years out, tapering only slightly to 75.6 percent at the 16-year mark. When meshed with day-to-day markers like body mass and physical movement, the model’s accuracy surged—hitting 90.4 percent at five years and 82.2 percent across sixteen. 

Dr. Yu added, “Our model echoed its precision in an entirely different group in China, underscoring its resilience and broad applicability,” as per SciTechDaily.com. 

Still Waters Run Deep 

Despite its brilliance, the study remains observational—it detects links, not causes. But with pathways still being explored, this discovery ushers in a fresh frontier, where blood murmurs truths long before pain speaks.

Beloved Spice Could Secretly Sabotage Your Medications, Study Warns – Are You at Risk? 

A recent study reveals cinnamon’s core compound could hasten drug metabolism, undermining the efficacy of prescription medications. Discover the hidden risks behind this cherished spice.

A recent scientific study has flagged an unsuspecting pantry staple as a potential troublemaker in your body’s drug-handling mechanics — cinnamon. 

Beneath its warm aroma and nostalgic taste, researchers at the University of Mississippi have identified cinnamaldehyde — the chief aromatic in cinnamon — as a molecular agitator. This compound can awaken certain cellular gateways (receptors) that speed up how your body clears specific medications, possibly rendering them less potent than intended. 

While a sprinkle atop your cappuccino likely won’t stir trouble, the study casts a cautionary spotlight on high-dosage consumption, especially via supplements, according to the New York Post. 

Dosing Dangers Lurking in Plain Sight 

“Health hazards may arise if hefty volumes of supplements are ingested without a clinician’s awareness or guidance,” stated Shabana Khan, principal researcher on the project. 

Overindulgence could push your system to purge medications prematurely, sabotaging their intended purpose. 

Notably, the study points out that cinnamon oil — a frequent fixture in flavor additives and personal care products — shows minimal risk in this context. It’s the bark, particularly from Cassia cinnamon, that raises eyebrows. 

Cassia vs. Ceylon: A Spicy Identity Crisis 

Cassia cinnamon — a low-cost variety imported from southern China — harbors coumarin, a naturally occurring compound with blood-thinning traits. This could spell danger for individuals already navigating anticoagulant therapies. 

“Ceylon cinnamon, often dubbed ‘true cinnamon’ and sourced from Sri Lanka, bears far less coumarin, making it a safer bet,” explained Amar Chittiboyina, a co-author and deputy director at the National Center for Natural Products Research

Supermarket shelves mostly carry Cassia, cloaked in generic packaging as simple “ground cinnamon.” 

The Fine Line Between Healing and Harm 

Historically, cinnamon has earned praise for its alleged therapeutic potential — from leveling blood sugar to easing inflammation. But this fresh wave of evidence underscores the shadow side of overuse, as per the NY Post. 

People living with long-term health conditions — diabetes, hypertension, autoimmune disorders, or psychological ailments — should tread especially carefully. 

“Our top-line advice: always consult a health care professional before pairing any supplements with prescribed treatments,” Khan emphasized. “Supplements aren’t cures. They’re not crafted to heal, treat, or offset diseases.” 

Tread Gently With Nature’s Power 

Cinnamon might still spice up your life in meaningful ways — but when taken in heavy doses, it may quietly unravel the work of vital medications. 

As with any potent natural remedy, the key lies in mindful use — not blind enthusiasm.

Your Daily Diet Might Be Deadlier Than You Think — Find Out Why 

A profound study reveals the alarming link between ultra-processed foods and premature deaths across multiple nations, urging critical reevaluation of modern eating habits. 

Published

In a modern world saturated with quick-fix edibles, ultra-processed foods (UPFs) — brimming with excessive sugars, salts, and detrimental fats — now constitute a staggering 70 percent of the American food landscape. 

A fresh dissection of global datasets from the United States and seven other nations sought to gauge how many untimely, avoidable fatalities stem from the habitual ingestion of items like processed meats, packaged sweets, sugary beverages, and artificially sweetened breakfast cereals. 

Carlos Augusto Monteiro, emeritus authority in nutrition and public health at Brazil’s University of São Paulo, shared with CNN, “We scrutinized the peril of dying prematurely — between the ages of 30 and 69 — directly linked to escalating consumption of UPFs,” according to the New York Post

Monteiro’s research unveiled a stark reality: for every 10% augmentation in calorie intake from UPFs, the hazard of an early grave intensifies by nearly 3 percent. These findings surfaced in the latest edition of the American Journal of Preventive Medicine. 

Prior explorations have already tied UPFs to over 32 adverse health predicaments — encompassing heightened dangers of cardiac maladies, oncological disorders, Type 2 diabetes, and psychological afflictions. 

In the year 2018 alone, an estimated 124,000 preventable deaths in the U.S. were traced to UPF consumption, according to Eduardo Augusto Fernandes Nilson, principal investigator of this new revelation. 

From a grim perspective, about 74,000 Americans perished from fentanyl overdoses in 2022. 

Fernandes Nilson’s consortium employed an intricate computational model, examining health data from nearly 240,000 individuals and over 14,000 fatalities, to deduce the share of early deaths tied to UPFs. 

The calculated mortality rates oscillated between 4 percent in Colombia, a nation with minimal UPF consumption, to an unsettling 14 percent in heavy-consuming countries such as the United Kingdom and the United States, as per the New York Post. 

Brazil (low), Chile and Mexico (moderate), and Australia and Canada (high) were also encompassed in the study’s scope. 

“The amassed evidence underscores that UPF intake substantially aggravates the global disease burden. Thus, slashing their consumption must become a cornerstone of national dietary frameworks and public health mandates,” the researchers passionately advocated. 

Nevertheless, skepticism shadowed the findings. Nerys Astbury, a nutrition researcher and associate professor at the University of Oxford — detached from the study — emphasized to CNN that the investigation did not definitively prove causality between UPF ingestion and mortalities. 

Further dissent came from Sarah Gallo, senior vice president for product policy at the Consumer Brands Association, representing the processed food sector. Gallo contended to The Post, “This stands as another bewildering piece of research that could deepen consumer misunderstanding. Presently, no universally accepted scientific delineation of ‘ultra-processed foods’ exists,” as per NY Post. 

She cautioned, “Vilifying accessible, cost-effective, shelf-stable edibles might inadvertently curtail access to vital nutrient-rich foods, jeopardize dietary quality, escalate food-borne risks, and widen health inequities.”
