Dr. Schaffner discusses the recent increase in the incidence of measles infections.
MedicalResearch.com: What is the background for this study?
Response: The fundamental reason leading to the increase in measles cases in the US is that some parents are withholding their children from routine measles vaccination: Failure to vaccinate. As a result, there are neighborhoods, schools, and communities that now have vaccination rates substantially below the 92% to 95% needed to prevent outbreaks of infection. Measles is the most contagious virus we know, so it takes very high vaccination rates to prevent transmission and to avert outbreaks.
Vaccine hesitancy has many causes: Lack of knowledge of the severity of measles, concern over vaccine side-effects, low trust in public health, a desire to do things more “naturally” and it can also have political overtones, among others.
The measles vaccine is extraordinarily effective; the routine two-dose series confers 97% to 98% protection for life. The rare “breakthrough” infections that occur in vaccinated persons are generally milder, with fewer complications than in persons who are unvaccinated.
The US was certified as having eliminated measles in 2000 because of high vaccination rates across the country. Sadly, the US is likely to lose that designation because of sustained measles transmission, reverting us back to the bad old days. It is particularly sad for any of our children to have to endure measles and its consequences. All these cases could have been prevented by vaccination.
MedicalResearch.com: What roles do a decrease in US immunization rates and/or increased immigration from under-vaccinated area play in this increase?
Response: The substantial majority of unimmunized children in the US were born and raised in this country. They usually are members of middle- or upper-income families. The most frequent importers of measles into the US are our own unimmunized children who travel abroad, encounter measles virus and bring it back to their homes where the virus then spreads among the child’s schoolmates and playmates, creating an outbreak.

MedicalResearch.com: What is the background for this outbreak?
Response: India has reported 2 confirmed (PCR and ELISA) Nipah virus (NiV) cases in West Bengal State where the Kolkata megalopolis is located; the state borders Bangladesh. Symptom onset in both cases was late December 2025 in 2 health care workers. One patient has improved while the other remains in the ICU. All samples from 200 contact persons tested negative for NiV. No further confirmed cases have been detected in West Bengal
Bangladesh has reported 1 confirmed NiV case in Rajshahi Division which neighbors India. Symptom onset was January 21, 2026, and the patient expired on January 28. The patient reported no travel history but reported repeated consumption of raw date palm sap between 5 and 20 January. All 35 contact-persons are being monitored and have tested negative for NiV and no further cases have been detected to date.

Response: Alcohol consumption, especially heavy alcohol consumption, is associated with many health risks and nearly 200 different health conditions and diseases. Reducing alcohol consumption reduces the risks and harms from alcohol. Previous research has demonstrated that people have reduced their alcohol consumption when they have access to cannabis. Cannabis beverages have emerged in States where cannabis is legal for adult or medical use.

MedicalResearch.com: What is the background for this study?
Response: Medical assistance in dying (MAiD) was legalized in Canada in June of 2016 for Canadians who were facing a reasonably foreseeable natural death and met an explicit set of eligibility criteria as determined by qualified health care providers (physicians or nurse practitioners). In 2021, the legislation was extended to include the possibility of MAiD for persons who were suffering from a ‘grievous and irremediable’ medical condition but for whom natural death was not immediately foreseeable. As assisted dying represented a significant change in available options for Canadians with terminal or chronic conditions, requiring significant practice adaptations and including numerous legal, social, ethical, moral implications, the health research community has been working in consultation with clinicians, service providers and governments to generate knowledge that ensures safe, ethical and equitable practice in this regard.

Response: Per- and polyfluoroalkyl substances (PFAS) are a class of artificially synthesized chemicals widely used in industrial production and consumer goods manufacturing. These substances are persistent in the environment, can accumulate through the food chain, and enter the human body and build up over time, posing a potential threat to health. As an important component of the global diet, marine fish may serve as a major source of PFAS intake for humans. However, the contribution of marine fish as a source of PFAS exposure and the associated health risks still lack systematic assessment on a global scale.

Response: While CD19-targeted CAR T cell therapy has garnered clinical success and FDA approval for the treatment of large B cell lymphoma, approximately half of patients suffer from primary resistance or relapse. Increasing evidence suggests that resistance mechanisms are supported by the tumor microenvironment (TME). Cytokines secreted by CAR T cells can remodel the TME, determining the phenotype and function of other immune cells.

MedicalResearch.com: What is the background for this study?
Response: Coronary computed tomography angiography (CCTA) is a non-invasive heart scan used in the first-line investigation of patients with suspected stable coronary artery disease (CAD). While CCTA clearly shows blockages in coronary arteries, it is limited in its ability to estimate reduced blood flow, which is necessary to diagnose angina.
An artificial intelligence-based tool (Heartflow) has been developed that analyses CCTA images and provides an estimate of blood flow: CT-derived fractional flow reserve (FFR-CT). The real-world, retrospective English FISH&CHIPS study demonstrated that including FFR-CT as a decision-making tool in the diagnosis of stable CAD reduces the number of subsequent invasive and non-invasive tests performed.
Whether FFR-CT could also be used prognostically, to predict future major cardiovascular events, was not fully understood. Previous studies have had small patient numbers, short follow-up and investigated combined cardiovascular outcomes. We performed an analysis on the national FISH&CHIPS population, which was large enough to determine if FFR-CT adds incremental value to traditional cardiovascular risk factors in predicting cardiovascular outcomes and death.
