Researchers Use AI Tools to Uncover Connections Between Radiotherapy for Lung Cancer and Heart Complications
Researchers from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, have used artificial intelligence tools to accelerate the understanding of the risk of specific cardiac arrhythmias when various parts of the heart are exposed to different thresholds of radiation as part of a treatment plan for lung cancer. Their results are published in JACC: CardioOncology.
“Radiation exposure to the heart during lung cancer treatment can have very serious and immediate effects on a patient’s cardiovascular health,” said corresponding author Raymond Mak, MD, of the Department of Radiation Oncology at Brigham and Women’s Hospital. “We are hoping to inform not only oncologists and cardiologists, but also patients receiving radiation treatment, about the risks to the heart when treating lung cancer tumors with radiation.”
The emergence of artificial intelligence tools in health care has been groundbreaking and has the potential to positively reshape the continuum of care, including informing treatment plans for patients with cancer. Mass General Brigham, as one of the nation’s top integrated academic health systems and largest innovation enterprises, is leading the way in conducting rigorous research on new and emerging technologies to inform the responsible incorporation of AI into care delivery.
For patients receiving radiation therapy to treat non-small cell lung cancer (NSCLC), arrhythmias or irregular rhythms of the heart can be common. Because of the close proximity of the heart to the lungs and with NSCLC tumors being near or around the heart, the heart can receive collateral damage from radiation dose spillage meant to target the cancer tumors. Prior studies have found that this type of exposure to the heart is associated with general cardiac issues. However, this nuanced study demonstrated that the risk for different types of arrhythmias can vary significantly based on the pathophysiology and cardiac structures that are exposed to different levels of radiation.
In order to classify the types of arrhythmias that are associated with cardiac substructures receiving radiation, researchers conducted a retrospective analysis on 748 patients in Massachusetts, who were treated with radiation for locally advanced NSCLC. The arrhythmia subtypes cataloged included atrial fibrillation, atrial flutter, other supraventricular tachycardia, bradyarrhythmia, and ventricular tachyarrhythmia or asystole.
The team’s statistical analyses indicated that about one out of every six patients experienced at least one grade 3 arrhythmia with a median time of 2.0 years until the first arrhythmia. Grade 3 classifications are considered serious events that likely need intervention or require hospitalization. They also found that almost one-third of patients who experienced arrhythmias also suffered from major adverse cardiac events.
The arrhythmia classes outlined in the study did not entirely encompass the range of heart rhythm issues that are possible, but the authors note that these observations still create a better understanding of the possible pathophysiology pathways and potential avenues for minimizing cardiac toxicity after receiving radiation treatment. Their work also offers a predictive model for dose exposure and the type of expected arrhythmia.
For the future, the researchers believe that radiation oncologists should collaborate with cardiology experts to better understand the mechanisms of heart injuries and their connection to radiation treatment. In addition, they should take advantage of modern radiation treatment to actively sculpt radiation exposure away from the specific cardiac regions that are at high risk for causing arrhythmias. According to Mak, this study, alongside previous research, will help with surveillance, screening, and informing radiation oncologists on which parts of the heart to limit radiation exposure to, and in turn, mitigate complications.
“An interesting part of what we did was leverage artificial intelligence algorithms to segment structures like the pulmonary vein and parts of the conduction system to measure the radiation dose exposure in over 700 patients. This saved us many months of manual work,” said Mak. “So, not only does this work have potential clinical impact, but it also opens the door for using AI in radiation oncology research to streamline discovery and create larger datasets.”

Female circumcision in Russia – exists and is not punished
Every year, millions of women and girls in the world are subjected to the procedure “female circumcision.” In the process of this dangerous practice, women have part or all of their external genitalia removed. Among the victims are also residents of the North Caucasian republics of Russia, and the Russian authorities do not punish the execution of the violent procedure.
How this violent religious-ritual tradition exists in modern Russia, do the authorities and the clergy try to fight it – reveals the Russian publication of Verstka.
What is “female circumcision”
Female circumcision is a procedure that is accompanied by either trauma or partial or complete amputation of the external genitalia. As a result of the procedure, sensitivity is reduced and the woman may lose the ability to have an orgasm.
Not for medical reasons
The procedure is not performed for medical reasons, but for ritual or religious reasons to suppress female sexuality. That is why in the international medical community this term is not used, but is called “female genital mutilation operations”. International law considers them an attack on the health of women and girls, a form of violence and discrimination.
Victims
Victims of female circumcision are girls up to the age of 15. According to data from the World Health Organization (WHO), in 2024, more than 230 million women in the world suffered from such operations. They are mostly carried out in African, Asian, Latin American and Middle Eastern countries. But there are also victims of female circumcision in Russia among the residents of the North Caucasian republics – Dagestan, Ingushetia and Chechnya.
Injuries
The procedure has serious negative consequences for women’s health – from serious injuries to death due to blood loss. In addition to physical trauma and the shock of pain, female circumcision disrupts the natural functioning of the body. Women and girls may suffer from infections, their genitourinary system may be damaged, they may experience pain during sexual intercourse, menstrual disorders may occur, and the risk of complications during childbirth and death of the mother and the newborn increases by 50%.
Why do they do it?
The “necessity” of such operations is justified by honoring traditions or religious motives. In some cultures, it is part of the rite of female initiation or entry into adult life. Female circumcision is often associated with Islam, including in the Russian Federation.
Prevents lust
In the words of Dagestan journalist Zakir Magomedov, “in the local religious press, which is issued by the official clergy, articles are published in which it is written that female circumcision has a beneficial effect on a woman and protects her from lustful thoughts and desires, and is even beneficial for a woman.”
Female circumcision is performed by people without medical training, and old pocket knives or cattle shears are used as tools.
Control over female sexuality
In almost all cases, the purpose of the procedure is defined as control over female sexuality: “not to be hoika”, “not to freak out”. The official clergy of Dagestan include female circumcision in religious duties, although it is not mentioned in the Koran. Some Muslims, in addition to the Koran, are also guided by the Sunnah – traditions from the life of the Prophet Muhammad and statements of authoritative religious figures. Therefore, in some cases, female circumcision among Muslims can be interpreted as permissible, desirable and even mandatory.
Officially, the Russian authorities are against it
“All women should be circumcised so that there is no debauchery on Earth, to reduce sexuality”, this is how the head of the Coordination Council of Muslims of the North Caucasus, Ismail Berdiev, reacted to the revelations of the “Legal Initiative” organization in 2016, which confirmed the existence of practice. Later, Berdiev clarified that “he did not call for female circumcision”, but only spoke about the “problem of debauchery”, with which “something must be done”.
The Russian Ministry of Health condemns the procedure, and the prosecutor’s office of Dagestan conducts an investigation and finds no confirmation of the facts presented in the report of “Legal Initiative.”
The deputy of the State Duma from “United Russia” Maria Maksakova-Igenbergs proposes to introduce the concept of “women’s discrimination on religious grounds” into the Penal Code, and that the punishment for “female circumcision” be 10 years in prison. The Ministry of Justice of Russia does not support Maksakova’s initiative, clarifying that the procedure falls under the Criminal Code of the Russian Federation, and more precisely under the paragraphs on “deliberately causing severe, medium and light harm to health, as well as causing harm to carelessness.”
North Caucasus
According to the “Legal Initiative” organization, in the middle of the last decade in Dagestan, at least 1,240 girls were subjected to the procedure annually. The majority of the men surveyed were categorically against the ban on female circumcision, explaining their motive not only with Islam, but also with local traditions and the desire to control the morality of women. Part of the respondents expressed an opinion against the procedure, arguing that the lack of sensitivity in women lowers the quality of sex in men as well.
And in Moscow
In 2018 one of the Moscow medical clinics announces the service of “female circumcision” for ritual and religious reasons for girls from 5 to 12 years old. On the clinic’s website, it was noted that “the operation should be performed not at home, but in a medical clinic.” After a wide public response, the clinic removed the information from its website, but an investigation was carried out, which found the existence of the procedure and other violations. A warning has been issued and the clinic is still open!
First conviction without penalty
Despite the fact that in its second report the organization “Legal Initiative” notes the disappearance of the practice in Chechnya and Ingushetia, the inhabitants of these regions remain in danger. In the spring of 2020, the father of a 9-year-old girl invited him to Magas (the capital of Ingushetia) for a visit and took him to a vaccine clinic. There, female circumcision was forcibly performed on the child. The value of the “service” is 2000 rubles. The little girl, in her bloodstained dress, was then put on a bus back to Chechnya, where she was hospitalized for severe blood loss. The father explains his motive as follows: “So that he doesn’t get excited.”
A criminal case has been opened against the gynecologist who performed the circumcision for intentionally causing minor harm to health. The case has been going on for a year and a half. The judge called on the parties to reconcile, adding that “the girl cannot be helped anyway”. In the end, the doctor was found guilty and fined 30,000 rubles, but was released from serving the sentence due to the statute of limitations. No criminal proceedings have been initiated against the clinic.
In the same year, the mufti of Dagestan issued a fatwa and recognized the removal of the external genitalia as forbidden in Islam, but clarified that “female circumcision” meant only hudectomy — the removal of the foreskin of the clitoris. This is also a crippling procedure, human rights defenders insist.

Four executed for producing illegal alcohol in Iran
Iranian authorities have executed end of October four people convicted of selling illegal alcohol, which poisoned and killed 17 people last year. More than 190 people who consumed the dangerous drink were hospitalized.
The death sentence against the accused in the case was carried out in the Karaj Central Jail.
According to human rights organizations including Amnesty International, Iran carries out the highest number of executions per year after China.
After the Islamic Revolution in 1979, Tehran banned the production and consumption of alcoholic beverages. Since then, the sale of illegal alcohol on the black market has flourished, leading to mass poisonings. The latest case, reported by Iranian media, has killed around 40 people in northern Iran in recent months.
Only Iran’s recognized Christian minorities, such as the country’s Armenian community, are allowed to produce and consume alcohol, but discreetly and only at home.

What is food neophobia – the fear of trying new dishes
Everyone has heard of anorexia and bulimia. But these eating disorders are far from the only ones.
There are people around the world who can only eat certain colored foods. Still others are addicted to water. About 5% of women between the ages of 15 and 35 are affected by some type of eating disorder. Among them are those with neophobia – the inability to try a new type of food. This problem sometimes also affects young children. For them, experts advise parents not to force them, but to explain to them the benefits of a given product. It is also an option to put them on the table in the company of other children who will set a good example.
Neophobia usually disappears around the age of 6. For some people, however, it remains a problem for much longer.
A possible explanation for this condition could be something happening in the person’s life – like choking on food, for example. As a result, a person may begin to avoid a certain type of food and thus give his phobia a “field of expression”.
The reasons for neophobia may lie not only in the psyche, but also in physical features. This disorder is genetically transmitted.
