A long-term study published in JAMA Network and reported by Deník followed around 131,000 people from the United Kingdom and the United States for up to 43 years.
The participants, who primarily worked in the healthcare sector, regularly reported their consumption of coffee and tea.
Over the study period, more than 11,000 cases of dementia were recorded, corresponding to 8.4 percent of participants.
The aim was to examine how daily habits may be linked to brain function.
Uncertainty in the results
Researchers and other experts emphasize that the findings cannot be interpreted as a direct causal relationship.
The study is based on observations rather than controlled experiments. In addition, self-reported data may affect accuracy.
It is also noted that the results do not necessarily apply to the entire population, as the participants share a relatively uniform background.
Caffeinated beverages
The findings show that individuals with a moderate intake of caffeinated beverages had a lower incidence of dementia, as well as slightly better performance in memory and cognitive tests.
The lowest risk was observed among those who consumed around two to three cups of coffee or one to two cups of tea per day. This association was not found for decaffeinated coffee.
Moderate daily consumption of coffee or tea may be associated with a lower risk of dementia, but it does not prove a direct protective effect.
Traditionally, colorectal cancer is treated with surgery followed by chemotherapy, but newer clinical data suggest alternative sequencing, writes SciTechDaily.
In a UK phase trial, patients with stage II and III colorectal cancer were treated with immunotherapy before surgery.
Participants received up to nine weeks of treatment with pembrolizumab prior to surgery, after which their disease course was systematically monitored.
The UCL trial included 32 patients with a specific genetic profile, representing a small proportion of colorectal cancer cases.
This subgroup is known to respond differently to treatment compared with other patients.
Biological mechanisms and monitoring
Alongside treatment, individualized blood tests were developed to measure circulating tumor DNA.
These analyses made it possible to identify early signs of treatment response and assess the risk of recurrence.
The results showed a clear correlation between the disappearance of tumor DNA in the blood and the absence of disease over time.
In addition, immunoprofiling of tumor tissue was used to predict which patients were most likely to benefit from the treatment.
Implications for future treatment
Long-term follow-up over 33 months showed no cases of recurrence among participants, a marked contrast to standard treatment courses, where around a quarter of patients experience recurrence within three years.
At the same time, significant tumor reduction prior to surgery was observed in a large proportion of patients.
These results indicate that immunotherapy before surgery may change the prognosis for selected colorectal cancer patients and potentially reduce the need for subsequent treatment.
The timing of treatment may be crucial for long-term disease control in specific patient groups.
The study included both organic and conventional varieties from well-known brands and supermarkets.
Findings in the analyses
The results show that no pesticides were found in the products. However, heavy metals such as mercury, arsenic, and especially cadmium were detected.
According to the study, these substances occur naturally in the environment, but they can also result from human activity. Cadmium was found in all the tested products.
A report from the French food safety authority Anses, cited by BFM, also shows that diet is the largest source of cadmium exposure.
It can account for up to 98 percent of total exposure among non-smokers.
Health risks
Authorities have set a limit on how much cadmium should be consumed per week.
The study shows that a daily portion of oatmeal can make up a large part of this limit, especially if other foods such as rice and chocolate are also consumed.
Mycotoxins were also found in some products. These are substances produced by fungi that can affect the body with long-term intake.
Oatmeal can contribute to the body’s total intake of cadmium and other unwanted substances, even though it is often perceived as healthy.

Novo Nordisk has entered into a collaboration with OpenAI to use artificial intelligence in the development of new medicines, according to the media outlet Il Fatto Alimentare.
The goal is both to discover new compounds and to make production more efficient, following previous issues with medicine supply.
The agreement comes at a time when competition in the obesity drug market is intensifying.
According to analyses, the market could reach very high valuations over the next ten years.
The company has previously implemented major cost-cutting measures, highlighting that the industry is undergoing change.
Technology in research
Researchers from Stanford Medicine have also used artificial intelligence to study how the body regulates appetite, publishing their findings in Nature.
They have identified a new peptide that can influence appetite without the side effects often seen in current treatments.
The research was based on existing knowledge of hormones that affect blood sugar and hunger.
Using a computer program, the scientists analyzed thousands of potential molecules.
They then tested the most promising candidates in the laboratory on brain cells that control hunger and satiety.
This method made it possible to identify relevant candidates more quickly than traditional approaches.
Animal trials
The most promising results were subsequently tested on animals such as mice and pigs.
These trials showed a significant reduction in food intake and an improvement in the body’s metabolism.
No clear side effects were observed in the experiments. At the same time, analyses indicated that the compound works differently from existing medications.

There are several signs that you may not be drinking enough water. These include dark urine, fatigue, headaches, and a sluggish digestive system.
These symptoms occur because the body lacks the fluids it needs to function optimally.
Water needs are not the same for everyone but depend, among other things, on weight, temperature, and activity level, according to the outlet Tua Saúde.
Digestion and absorption
Water plays a role in digestion. It helps the body break down food and absorb nutrients such as vitamins and minerals.
According to a review in Nutrition Reviews, fluid intake affects how the stomach and intestines function.
If the body lacks fluids, absorption may be reduced, which can lead to abdominal discomfort.
Practical recommendations
A common rule of thumb is to drink around 30 to 35 milliliters of water per kilogram of body weight per day.
For a person weighing 70 kilograms, this corresponds to approximately 2 to 2.5 liters daily.
It is best to drink water consistently throughout the day. Needs may increase in hot weather, during exercise, or illness. Fluids can also be obtained from foods such as fruits and vegetables.
Dreams are a natural part of sleep and arise when the brain processes experiences and emotions.
They are often most vivid during REM sleep, when the brain is highly active.
Stress, depression, and poor sleep can make dreams more intense and easier to remember.
During the coronavirus pandemic, many people experienced this, which researchers link to increased mental strain.
The same type of influence is often seen in seriously ill individuals, where both stress and sleep problems play a role.
Recurring patterns
According to a study published in Death Studies and reported by the media outlet Lrytas, based on the experiences of 239 professionals in Italy, many dying patients have similar dreams.
Several describe experiences in which they see deceased family members or move toward symbols such as light, doors, or stairs.
Researchers believe that such dreams may help create calm and understanding in a difficult situation.
At the same time, there are also more unpleasant dreams, which may reflect fear or inner conflicts in patients.
Unresolved answers
Although the patterns recur, the causes are not yet fully understood. Researchers point out that both psychological and cultural factors play a role, but more knowledge is needed.
Many patients do not speak openly about their dreams, making the phenomenon more difficult to study in detail.
These dreams often occur in the final phase of life and may have special significance for the individual.
Brazil nuts have become popular as a nutrient-rich snack with several health benefits.
They contain a range of essential vitamins and minerals that can affect the body in different ways.
Here is an overview of what happens when they become a regular part of your diet, according to EatingWell.
High content of selenium

Researchers from Mass General Brigham and Rush University Medical Center studied 1,338 older individuals over a period of up to 19 years, according to Illustreret Videnskab.
Participants wore a wrist-based activity monitor for 10 days, which recorded their sleep and rest patterns throughout the day.
The results, published in JAMA Network Open, provided precise data on when and for how long participants slept during the daytime.
Timing of naps
The findings revealed clear differences in participants’ sleep patterns.
Individuals who slept longer during the day had higher mortality rates. The same applied to those who took more frequent naps.
In addition, the timing of naps made a notable difference. Morning naps were associated with higher mortality than those taken later in the day.
Link to diseases
The researchers emphasize that the findings do not establish a direct causal relationship, but rather indicate an association.
An increased need for daytime sleep may be linked to conditions such as cardiovascular disease, circadian rhythm disturbances, or neurodegeneration.
It may also reflect more general health issues.
The naps themselves are not necessarily the problem. However, changes in sleep patterns among older adults may serve as an early indicator of illness.
Therefore, such changes could be important to monitor in healthcare and prevention efforts.

Asthma in young children is a common condition, affecting up to one in five. It often presents as coughing, shortness of breath, and recurrent respiratory infections.
Researchers have long suspected that part of the explanation may already be found during pregnancy.
A new study published in Cell Reports Medicine and reported in a press release from Ritzau shows that infants may exhibit differences in their airways early in life.
As early as one month of age, variations in bacteria and immune responses can be measured.
These differences are associated with how often the child develops infections, which in turn may increase the risk of asthma later on.
Not all are affected equally
The study is based on data from several hundred mothers and children who were followed for up to ten years.
Researchers compared blood samples taken during pregnancy with the children’s health outcomes.
The results also show that omega-3 supplements do not have the same effect on everyone.
Some children experience a reduced risk of asthma, while others are not affected.
This suggests that prevention may need to be tailored to the individual rather than applied uniformly.
Fatty acid molecule
Although the researchers cannot yet apply the findings directly in practice, they point to a possible explanation.
A specific fatty acid molecule, known as 12-HETE, appears to play a role.
Children of mothers who did not have this molecule in their blood during pregnancy more often developed asthma and had more respiratory infections.
Conditions during the fetal stage may therefore have significant implications for a child’s health.
In a French Alpine village with only a few hundred residents, 16 people were diagnosed with ALS.
This is an unusually high number for such a small area, reports Göteborgs-Posten.
ALS is a disease that gradually paralyzes the body’s muscles and often leads to death within a few years.
Cause still unknown
Researchers do not yet know exactly why ALS develops. In around 90 percent of cases, there is no clear explanation.
The disease is believed to result from a combination of genetic factors and environmental influences.
For this reason, scientists are also examining whether certain locations or habits may increase the risk.
A toxic mushroom draws attention
A study published in the Journal of the Neurological Sciences in 2021 shows that several of those affected in the village had eaten the false morel mushroom.
The mushroom is toxic and banned in France, but in some parts of the world, such as Sweden, it may be sold if properly prepared.
Nevertheless, authorities advise against consuming it due to health risks.
Researchers believe there may be a link between the mushroom and the disease, but they cannot prove it.
It is likely that several factors interact and that no single cause alone can explain why the disease develops.
