Reactions: WHO estimates 35 million new cancer cases worldwide by 2050

By 2050, there will be more than 35 million new cases of cancer worldwide, an increase of 77% from the 20 million cases reported in 2022. These are projections made by the WHO's International Agency for Research on Cancer (IARC), which has published the latest estimates of the global burden of cancer. Using data from 185 countries, IARC estimates that in 2022 lung cancer was the most common cancer worldwide, with female breast cancer in second place, followed by colorectal, prostate and stomach cancer. The authors stress the urgent need to address inequalities around these diseases.

Reactions: 38% of dog owners say they give cannabinoids to their dogs, according to Danish survey

In an anonymous online survey of dog owners in Denmark, 38% of respondents said they administered cannabinoid products - such as cannabidiol drops - to their pets without a prescription, even though their use is not legal in animals. Reasons given included pain, behavioural problems and allergies in their dogs. Some 2,000 people responded to the survey, the results of which are published in the journal PLoS ONE.

Reactions: five cases of Alzheimer's described that may have been transmitted by growth hormone treatments from cadavers

Researchers have described five cases of people in the UK who developed Alzheimer's-like dementia after being treated as children with growth hormone from cadavers. The treatment was administered between 60 and 40 years ago. This suggests that the disease could be transmitted. However, the authors point out that this is a very rare occurrence and could have been caused by repeated exposure to a type of hormone that is no longer used. The results are published in the journal Nature Medicine.

Reaction: Colorectal cancer death rates among 25-49 year olds in the EU to rise by 2024

International research estimates that by 2024 there will be approximately 1,270,800 deaths from different types of cancer in the European Union (EU) as a whole. In the specific case of colorectal cancer, the researchers estimate that mortality rates will increase among people aged between 25 and 49 in the EU. In Spain, the increase will be 5.5 % in men. The authors of the research, published in the Annals of Oncology, attribute this increased mortality to overweight, obesity and alcohol consumption in this age group.

Reactions: study links heavy metals to ovarian ageing

Heavy metals - including arsenic, cadmium and mercury - may adversely affect the ovaries of women approaching menopause, a study claims. Those with high levels of metals in their urine had lower levels of anti-Müllerian hormone, indicating diminished ovarian reserve - fewer oocytes in the ovaries compared to other women of that age. The authors, whose study is published in The Journal of Clinical Endocrinology & Metabolism, used urine data from more than 500 women in the US up to 10 years before their last menstrual period.

Reaction: researchers study indicators that can predict a migraine using data from an app

US researchers have analysed data from 477 people who, using a mobile app, recorded their moods, energy levels and migraine occurrence four times a day for two weeks. Morning attacks were associated with poorer self-rated sleep quality and less energy the day before. Stress and high-energy states were linked to headaches in the afternoon, adds the study, which is published in the journal Neurology.

Reaction: gene responsible for heart malformations in people with Down syndrome identified

People with Down syndrome often have heart problems, which can affect their life expectancy. However, the genes responsible among the 230 possible candidates were not known. A team of researchers used human tissue and mouse embryonic hearts and concluded that an extra copy of the DYRK1A gene is important in the process. In addition, they have tested a treatment in early gestation in mouse models that reduces its consequences. The research is published in Science Translational Medicine.

Reaction: study suggests that pregnant women who follow vegan diets are at increased risk for preeclampsia and low birth weight babies

Women who follow vegan diets during pregnancy may have an increased risk of developing preeclampsia and giving birth to underweight newborns, suggests an observational study published in Acta Obstetricia et Gynecologica Scandinavica. In the investigation, more than 65,000 women identified themselves as omnivores, more than 800 as vegetarians -in some of their different modalities- and 18 as vegans.

Reaction: Weight loss alone has little effect on diabetes control, study finds

Researchers at the University of Hong Kong have analysed data from more than 37,000 patients with type 2 diabetes followed for several years. Although some clinical trials have shown that weight loss can be quite effective in controlling the disease, the study data indicate that in the long term and 'in the real world' this is only achieved in 6% of patients. The results are published in the journal Plos Medicine.

Reactions: possible markers found in the blood of persistent covid patients

A study published in the journal Science has analyzed the set of proteins present in the blood of 113 people with covid-19 and 39 healthy people. According to their results, patients with persistent covid had a higher amount of proteins related to complement activation, a system involved in the inflammatory and immune response. In addition, there was an increase in antibodies against cytomegalovirus and Epstein-Barr virus. According to the authors, "available therapies targeting the terminal complement pathway could offer new treatment strategies for persistent covid."
