A new study has found that a combination of two drugs could enhance the immune system to treat one of the most common types of cancer in the world, bowel cancer. Also known as colorectal cancer, despite its widespread presence, the treatment options for this condition are limited. What the study specifically found was that this procedure could shrink the tumours caused by this condition by around 60%.

What Are The Drugs Involved

The trial involved the use of two immunotherapy drugs, botancilimab and balstilumab. It is a monoclonal antibody that works to stimulate the body's immune system to attack cancer. The study is a rather significant find, as it’s the first time that a consistent and durable response to immunotherapy has been reported in patients with solid MSS mCRC tumours.

The study was divided into several phases for more than 6 months. In the US trial, around around 101 patients with microsatile stable metastatic colorectal (MSS-mCRC) tumours showed a decrease . Around 61% of the patients experienced tumour shrinkage or stabilization after combined treatment with votancilumab and balstilumab. When it comes to downsides, diarrhea and fatigue were found to be the most common side effects or side effects of this drug.

These results are interesting and open to exploration. To date, immunotherapy has not been effective in patients with CNS-mCRC tumors. This study demonstrates the potential of the combination of botenlimab and balstilimab in the treatment of CNS mCRC, providing new hope for people diagnosed with colon cancer.

What Could This Mean For Bowel Cancer Treatment In The Future

The study is currently in the final stages of clinical trials, and the US Food and Drug Administration (FDA) hopes to quickly gain approval for its use because of the importance of this area that affects many people. The efficiency shown demonstrates the potential of botansilimab to contribute to broad antitumor immunity.

All in all, the combination of botensilimab and balstilimab represents a promising new direction in the treatment of colorectal cancer. This breakthrough could improve conditions for many patients worldwide and lights a new hope in the fight against this common disease. The results of this study show the effectiveness of immunotherapy in this field and how its potential to transform cancer treatment can only grow in the years to come.

Tiny plastic particles may be making their way into one of the body's most protected organs, the brain, according to new research. This has raised concerns about the long-term health effects of microplastic exposure, particularly on brain health.

In a study published in Nature Medicine, researchers found that microplastics and nanoplastics were present in brain tissue, with significantly higher concentrations than in liver and kidneys.

One of the most important findings is that these particles can cross the blood-brain barrier, a protective shield that normally blocks harmful substances from entering the brain.

The researchers analysed brain tissue samples collected over several years and observed that they contained seven to 30 times more plastic particles than other organs.

They also found an increase in brain plastic concentrations in more recent samples, reflecting the growing burden of plastic pollution worldwide in the last few years.

"Our data suggest a trend of increasing concentrations of micro- and nanoplastics in the brain," the study authors wrote. They stressed that the findings do not prove these particles cause disease.

Could Microplastic Exposure Increase Dementia Risk?

The researchers also reported higher concentrations of plastic particles in brain tissue from people diagnosed with dementia.

However, they cautioned that the study only identified an association and cannot determine whether microplastics contribute to dementia or whether brains diseased with dementia simply accumulate more particles.

Scientists are still trying to understand how these particles do harm once they reach the brain. Proposed theories include triggering inflammation, disrupting communication between nerve cells, or affecting blood flow, but none have yet been confirmed in humans.

How Can Microplastics Get Into The Brain?

Since nanoplastics are extremely small, researchers believe some may pass through the blood-brain barrier and become trapped in brain tissue.

The study found polyethylene, commonly used in food packaging and plastic bottles, was the most abundant type detected in the brain tissue.

Scientists emphasise that it is too early to conclude that microplastics directly damage the human brain.

"The findings are concerning, but they should not be interpreted as proof that microplastics cause neurological disease," the researchers emphasised. More studies are needed to determine whether the particles themselves are harmful or simply markers of environmental exposure.

How To Reduce Exposure To Microplastics?

While eliminating exposure entirely is nearly impossible, experts recommend practical steps that may lower intake:

• Avoid heating food in plastic containers.
• Choose glass or stainless steel for food and water storage when possible.
• Reduce consumption of heavily packaged and ultra-processed foods.
• Improve indoor ventilation and reduce household dust, another potential source of airborne microplastics.

The study adds to mounting evidence that microplastics are no longer just an environmental issue. They are increasingly being detected throughout the human body, including the blood, lungs, placenta and now the brain.

A new study by the US Centers for Disease Control and Prevention (CDC) has found that nearly one in three patients who were hospitalised were diagnosed with invasive mould disease (IMD) died during their hospital stay.

The findings highlighted the urgent need for better surveillance, hygiene, early diagnosis, and greater awareness among healthcare professionals.

The findings come from the surveillance study of invasive mould infections conducted by the CDC across four hospitals in Atlanta and Georgia, between 2020 and 2024.

What Did The Study Find?

Researchers identified 499 confirmed cases of invasive mould disease during the five-year study period. Around 33% of these patients died while hospitalised, while the overall 90-day mortality rate reached 45%.

Nearly half of the patients needed intensive care, and about 50% needed ventilation, highlighting just how severe these infections can turn.

Patients who had a recent or current COVID-19 infection were found to be even worse. Their 90-day mortality rate was 66%, compared with 41% among patients without COVID-19.

"Our findings demonstrate that invasive mold disease is associated with substantial illness and death," the CDC researchers wrote, adding that active surveillance can help improve understanding of how common these infections are and guide prevention efforts.

What Is Invasive Mould Disease?

Unlike the mould that grows on damp walls or spoiled food, invasive mould disease occurs when fungal spores enter the body through the lungs, wounds, or contaminated medical equipment and spread into deep tissues, blood vessels, or organs.

The infections are most commonly caused by fungi such as Aspergillus, Mucorales, Fusarium, and Scedosporium. Once inside the body, they can rapidly become life-threatening if not diagnosed and treated early.

Who Is Most At Risk?

The disease rarely affects healthy individuals. Instead, it primarily targets people whose immune systems are already weakened, including:

• Cancer patients undergoing chemotherapy
• Organ transplant recipients
• People taking long-term steroids or immunosuppressive drugs
• Patients in intensive care units
• Individuals recovering from severe COVID-19
• Older adults with multiple illnesses

Why Experts Are Concerned

One of the biggest challenges is that invasive mould disease is not a nationally reportable disease in the United States, meaning health authorities do not routinely collect nationwide data on cases. Researchers believe the actual burden may therefore be underestimated.

The CDC authors noted that active surveillance is essential to estimate disease incidence, identify outbreaks, and improve patient outcomes. They also highlighted that patients with COVID-19 experienced significantly more severe disease, suggesting clinicians should remain vigilant for fungal complications in critically ill patients.

Outside experts have also warned that factors such as climate change, extreme weather events, an ageing population, and rising antifungal drug resistance could contribute to an increase in serious fungal infections in the coming years.

Although invasive mould infections remain relatively uncommon, the study shows they carry an alarmingly high risk of severe illness and death among vulnerable patients. Researchers say increasing awareness, recognising symptoms early, improving hospital surveillance, and developing faster diagnostic tools could help identify infections sooner and improve survival.

Deadly superbug Candida auris remains a critical public health concern in the United States. Between 2022 and 2024, the number of clinical C. auris cases nearly doubled, rising from 2,882 to 6,197, according to the latest surveillance report from the US Centers for Disease Control and Prevention (CDC).

The multidrug-resistant fungal pathogen infected at least 7,000 people across 27 US states by early 2026, according to the CDC. However, the agency's latest Surveillance Summaries report focuses on trends between 2022 and 2024.

The CDC noted that the drug-resistant fungus continues to pose a major challenge for hospitals, nursing homes, and other healthcare facilities because it is difficult to treat and control.

"Candida auris is an emerging yeast that is frequently resistant to antifungal drugs. C. auris can cause invasive infections associated with high mortality and can colonize patients asymptomatically, which facilitates transmission in health care settings," the CDC said.

"Since it was first reported in the United States in 2016, C. auris has been identified in multiple states, with increasing numbers of cases reported annually. Monitoring national trends in cases identified through clinical testing and screening for colonization is critical to guide infection prevention and control efforts," the CDC report said.

Key Findings From the CDC Report

• 13,507 clinical Candida auris cases were reported to the CDC between 2022 and 2024.
• Annual cases increased from 2,882 in 2022 to 4,428 in 2023 and 6,197 in 2024.
• The annual growth rate slowed, falling from 53.7% (2022–2023) to 39.9% (2023–2024), even as total cases continued to rise.
• Adults aged 45 years and older accounted for 87.8% of clinical cases, while 61.0% of cases occurred in males.
• The most common specimen types were urine (31.5%) and blood (30.2%).
• The proportion of blood specimens declined over the study period, from 34.4% in 2022 to 30.2% in 2023 and 25.6% in 2024.
• Most clinical cases were identified in acute care hospitals (76.6%), followed by long-term acute care hospitals (17.8%).

The CDC said the continued increase in cases highlights ongoing transmission in healthcare settings and underscores the need for sustained infection prevention and control efforts, supported by federal, state, and local public health partners.

Why Is Candida auris So Difficult to Control?

Unlike many other infections, Candida auris spreads easily through contaminated medical equipment and direct person-to-person contact. It can also survive on surfaces and is resistant to many commonly used disinfectants, making outbreaks difficult to contain once the fungus enters a healthcare facility.

Health officials say the steady increase in cases each year points to ongoing transmission in healthcare settings.

Candida auris: Symptoms and Health Risks

• Candida auris can infect the bloodstream, wounds, ears, and other parts of the body.
• Symptoms vary depending on the site and severity of the infection
• Some infected people may have no symptoms (asymptomatic infection)

The fungus is especially dangerous in hospitals and nursing facilities because it can survive for long periods on surfaces such as doorknobs, counters, and bed rails. Its resistance to multiple antifungal drugs makes infections difficult to treat and eliminate.

Candida auris: Who's At High Risk?

A 2025 study published by Cambridge University Press found that Candida auris typically enters the body through devices such as catheters, breathing tubes, feeding tubes, or peripherally inserted central catheters (PICC lines).

The study, which included 321 patients, found that people with Candida auris generally had significant underlying illnesses, with an average age of 60–64 years.

More than half of the patients required intensive care unit admission, over one-third needed mechanical ventilation, and more than half required blood transfusions.

People with healthy immune systems are generally better able to fight the infection than those who are elderly or have serious underlying illnesses. The CDC has previously estimated that, based on limited patient data, 30%–60% of people with Candida auris infections have died, although many had severe underlying medical conditions.
