Stomach cancer is a type of cancer that develops in the lining of the stomach. Also, known as Gastric cancer, it affects the elderly more than the adult. According to the American Cancer Society, about 6 of every 10 people diagnosed with stomach cancer each year are 65 or older. Also, the lifetime risk of developing stomach cancer is higher in men (about 1 in 101) than in women (about 1 in 155).

A health expert, speaking to a leading media house, emphasized five common symptoms of stomach cancer that should not be ignored:

1. Unexplained weight loss: Losing weight without trying or experiencing an unexplained drop in appetite, which may signal cancer progression.

2. Pain in the upper part of the abdomen: Persistent or occasional pain in the stomach area, often after eating, can become more severe as the condition progresses.

3. Frequent vomiting after meals: Nausea, sometimes accompanied by vomiting, may occur especially after meals and is linked to cancer blocking or irritating the stomach.

4. Vomiting blood, which may appear coffee-colored: This can indicate bleeding in the stomach, often caused by ulcers or tumors, and requires immediate medical attention.

5. Black, tarry stools: This occurs when blood from the stomach is digested and passed through the intestines, signaling potential internal bleeding

There are also other concerning signs that should not be overlooked such as jaundice, unexplained weight loss, early onset of diabetes, dark stools, and loss of appetite. Health experts strongly advise seeking immediate medical attention if you notice any of these symptoms. If you or a loved one experience these signs, it's crucial to visit a physician for a thorough evaluation to rule out serious underlying health conditions.

How Does Stomach Cancer Spread?

Oncologist Dr Pankaj Kumar Pande, Director–Surgical Oncology, Max Super Specialty Hospital, Shalimar Bagh, Delhi explained that this form of cancer spreads through three main pathways: Direct spread, lymphatic spread, and bloodstream.

1. Direct Spread: In its early stages, stomach cancer can invade nearby tissues and grow into the deeper layers of the stomach or spread to surrounding organs such as the oesophagus, liver, pancreas, or intestines.

2. Lymphatic Spread: Cancer cells can travel through the lymphatic system. The most common areas affected are the regional lymph nodes near the stomach, particularly those around the liver and diaphragm.

3. Bloodstream: "Cancer cells can enter the bloodstream and travel to distant parts of the body," which is a common route for stomach cancer to metastasize to distant organs.

He further explained that cancerous cells spread from the original tumour to other parts of the body through a process called Metastasis. The most common sites for the spread are the liver, lymph nodes, peritoneum, lungs, bones, and ovaries.

With speed, sudden drops and dizzying twists at hundreds of feet in the air, roller coasters are meant to give riders an adrenaline rush and thrill. But a recent incident related to brain bleeding has shed light on the harmful impact of these extreme movements inside the brain.

A recent investigation found discovered that serious brain injuries have been allegedly linked to the X2 roller coaster at Six Flags Magic Mountain in California.

According to CNN, more than 100 people have allegedly suffered brain injuries after riding the attraction over the past two years. Three lawsuits were filed this week against Six Flags.

Two women who rode X2 just six days apart in July suffered severe brain haemorrhages and required emergency surgery. Doctors treating them attributed their injuries to rapid acceleration and deceleration experienced during the ride.

The cases raise the medical question of what happens to the brain when the body is subjected to sudden, powerful changes in speed and direction?

Can Roller Coasters Cause Brain Bleeds?

The brain is surrounded by cerebrospinal fluid, which cushions it against everyday movements and minor impacts. However, this protection has its own limits.

When a roller coaster suddenly accelerates, brakes or changes direction, the head and brain may not always necessarily move at exactly the same speed.

The brain can shift, stretch or rotate within the skull, placing strain on delicate blood vessels and nerve fibres. In extreme circumstances, these forces can tear blood vessels and cause bleeding inside the skull.

So it's not necessary that a person needs to hit their head against a hard surface to sustain a traumatic brain injury. Rapid rotational movements alone can sometimes cause significant damage to the brain.

What Is A Subdural Haematoma?

A subdural haematoma is a life threatening brain injury, in which the blood collects between the brain's outer protective covering, called the dura mater, and the brain's surface.

Sudden acceleration and deceleration can tear the veins that connect the brain to its surrounding structures.

As blood accumulates, pressure inside the skull increases. This can compress brain tissue and, in severe cases, require emergency surgery to remove the blood and relieve pressure.

G-Forces Are Another Factor

G-force means the acceleration experienced by the body relative to Earth's gravity. During sharp turns, steep drops and sudden brakes, roller coaster riders experience changing G-forces. However, G-force alone does not determine whether someone will sustain a brain injury.

The speed and direction of head movements, specially rapid rotation, may also contribute to brain bleeds. A small 2017 study found that roller coasters could produce brain movement and strain comparable to mild football headers. However, the researchers did not find evidence of an immediate risk of acute brain injury on the rides studied.

Warning Signs After Riding A Roller Coaster

Serious neurological injuries associated with roller coasters are considered to be rare. The Six Flags cases do not establish that an ordinary roller coaster rides will have the same risks as X2.

People with existing vascular abnormalities, previous head injuries or those taking blood-thinning medications may face additional risks.

A headache after a roller coaster ride may seem harmless, but certain symptoms require immediate medical attention.

According to the US Centers for Disease Control and Prevention, warning signs of a traumatic brain injury include worsening headaches, repeated vomiting, confusion, slurred speech, seizures, weakness and loss of consciousness. Symptoms can appear immediately or develop hours later.

A popular organic applesauce has been recalled in the US after routine testing by the US Food and Drug Administration (FDA) revealed high levels of patulin, a toxin produced by certain molds that can grow on apples.

Wakefern Food Corp. voluntarily recalled select containers of Wholesome Pantry Organic Unsweetened Apple Sauce after the patulin levels were found to exceed food safety limits. No illnesses linked to the toxin have been reported yet.

The recall involves 23-ounce plastic jars with UPC 04119005677 and a best-by date of June 16, 2027. The product was sold through ShopRite, Price Rite Marketplace, The Fresh Grocer, Gourmet Garage and Fairway Market.

What Is Patulin?

Patulin is a mycotoxin, meaning it is a toxic chemical produced by certain species of fungi or mold.

The FDA identifies molds from genera including Penicillium, Aspergillus and Byssochylamys as sources of patulin. Apples are one of the best-known sources, particularly when fruit is bruised, damaged, rotten or improperly stored.

When contaminated apples are used to make products like apple juice or applesauce, the toxin can remain it. The pasteurisation does not eliminate patulin, so simply heating an apple product is not a reliable way to get rid of the toxin.

How Dangerous Is Patulin?

The health concern depends on the amount and duration of exposure to patulin. According to the FDA, consuming food or beverages containing high levels of patulin may cause nausea and vomiting, while evidence also indicates that the toxin can damage cells. The agency monitors patulin because prolonged exposure to elevated levels may pose a serious health hazard.

The FDA has established an action level of 50 parts per billion (ppb) for patulin in apple juice, apple juice concentrates and apple juice products.

This does not mean that eating a food once above the regulatory limit automatically causes poisoning. Food safety limits are designed to control exposure and reduce potential health risks, particularly when contamination could occur repeatedly.

Patulin In Applesauce

Molds formed due to patulin can grow on apples that have been bruised, damaged or allowed to rot. Contamination can also happen during storage.

The problem can be difficult to identify simply by looking at the finished food. FDA guidance notes that some contamination can originate from internal problems like core rot that may not be obvious from the outside of an apple. Removing damaged fruit before processing is therefore an important control measure.

So, anyone who has the recalled Wholesome Pantry Organic Unsweetened Apple Sauce at home should not consume it.

Consumers should check the jar for the 23-ounce size, UPC 04119005677 and best-by date June 16, 2027. The company says recalled products can be returned to the store for a refund or replacement.

Stopping GLP-1 drugs such as Ozempic, Wegovy, Mounjaro and Zepbound may cause some of their cardiovascular benefits to fade, a large new study suggests.

Researchers from Washington University in St. Louis found that people who stopped GLP-1 treatment had a progressively higher risk of major cardiovascular events, including heart attack, stroke and death. After two years off treatment, their risk was 22% higher than among those who continued taking the drugs.

The findings, published in BMJ Medicine, are significant as GLP-1 drugs are widely used to treat type 2 diabetes and obesity and have also been shown to provide cardiovascular benefits.

What Did The Study Find?

Researchers analyzed health data from 333,687 US veterans with type 2 diabetes over up to three years. Of these, 132,551 had been prescribed GLP-1 drugs, while 201,136 had been prescribed sulfonylureas, another class of diabetes medicines.

Treatment status was reassessed every six months. About 26% of GLP-1 users stopped treatment completely, while another 23% had a treatment gap of at least six months before restarting.

The longer people remained off treatment, the greater their cardiovascular risk.

After one year without restarting, the risk of major cardiovascular events was 14% higher than among continuous users. After two years, it was 22% higher.

"There is enormous exuberance about starting GLP-1 drugs, but not nearly enough attention to what happens when people stop," said senior author Ziyad Al-Aly, a clinical epidemiologist at Washington University.

Continuous Treatment Showed Greater Benefit

People who remained on GLP-1 drugs throughout the three-year study had an 18% lower risk of major cardiovascular events than those taking sulfonylureas.

That translated to about four fewer major cardiovascular events per 100 people over three years.

Those who remained on treatment for two or 2.5 years before stopping also had lower cardiovascular risk, by 7% and 15%, respectively.

However, people who stopped before 18 months did not have a significant reduction in cardiovascular risk compared with those taking sulfonylureas by the end of the study.

Treatment Gaps May Weaken Heart Protection

Interrupting GLP-1 treatment and later restarting it was associated with less cardiovascular protection. While continuous users had an 18% reduction in major cardiovascular events, those who stopped and later restarted had an average 12% reduction.

Even a six-month treatment gap was associated with a 4% to 8% increase in cardiovascular risk compared with continuous use.

Al-Aly said many patients stop GLP-1 drugs because of "cost, side effects or shortages."

"When they stop, it's not just weight that comes back; they experience a resurgence in inflammation, blood pressure, and cholesterol. Weight regain is visible; the metabolic reversal is not," he said.

"Our data suggest this metabolic whiplash is detrimental to heart health," Al-Aly added.

Can Restarting GLP-1 Drugs Restore The Benefits?

Restarting treatment appeared to restore some cardiovascular protection, but not all of it.

The researchers said the findings suggest that cardiovascular benefits gained during GLP-1 treatment may diminish after treatment is interrupted.

"Clinicians should treat adherence to GLP-1 treatment as an important outcome in its own right -- not an afterthought," Al-Aly said.

He added that healthcare systems should help patients manage side effects, address cost barriers and understand that GLP-1 drugs are used to manage chronic conditions.
