A study by Massachusetts General Hospital investigators found that patients believed allergic to penicillin have significantly increased risks of contracting MRSA and C. difficile. The increased risk can be attributed to the use of broad-spectrum alternative antibiotics, which contribute to antibiotic resistance and virulent infections.
A recent study published in The BMJ found that patients with a recorded penicillin allergy are at an increased risk of developing MRSA and C difficile infections. The risk is largely due to the use of broad-spectrum antibiotics as alternatives to penicillin, which may be fueling the development of drug-resistant bacteria.

The CHILD Study also found that early introduction of common allergenic foods may reduce the risk of allergic sensitization and food allergy.
Severe asthma defined as asthma requiring high-dose long-acting B2-agonists and/or additional controller medication or frequent oral corticosteroid use, emphasizing patient adherence verification before diagnosis.
A recent study published in the Journal of Allergy and Clinical Immunology found that breastfeeding may increase the risk of developing hay fever and eczema, while not having a clear effect on asthma. Lifestyle factors such as socioeconomic status and body mass index also played a role in the study.

Participants who took the probiotic reported improvements in quality of life, including fewer nose symptoms and increased comfort during daily activities.
Lyme disease affects approximately 329,000 people annually in the US, with a focus on understanding how Borrelia burgdorferi adapts to survive in tick vectors and mammalian hosts. Dr. Seshu's research seeks to find better solutions to prevent the spread of Lyme disease.
Researchers confirm live Zika virus infects reproductive tract, replicates and causes disease in mouse models. Hormonal injection timing affects vulnerability to infection, with diestrus-infected mice showing no signs of disease despite viral persistence.
A study of 577 children living in Puerto Rico found that closer proximity to major roads was associated with higher levels of interleukin 31, a cytokine promoting allergic inflammation. This increase in IL-31 levels is linked to increased asthma risk and severity in genetically susceptible children.
The American College of Allergy, Asthma, and Immunology recommends introducing peanut-containing foods as early as 4-6 months for high-risk infants with severe eczema and/or egg allergy. Early introduction has been shown to benefit infants who are sensitized to peanuts in studies like LEAP.

Climate change may cause ragweed pollen allergy to more than double in Europe, affecting 77 million people by 2050. The number of people suffering hay fever is already estimated at 40% of Europeans, and the severity of symptoms may increase due to higher pollen concentrations and longer seasons.
A 20-year study shows that probiotic supplementation in newborns can provide long-term protection against allergies. Meanwhile, a new vaccine for cat allergies lasts 8 times longer than existing ones, while research on dairy farm kids' immunity to milk allergies may lead to an asthma vaccine.
A new study from the University of Otago suggests that childhood exposure to microbial organisms through thumb-sucking and nail-biting reduces the risk of developing allergies. The study found that children who engaged in these habits had lower rates of allergy development compared to those who did not.
