Article Synopsis
- A study was conducted to determine the frequency of food allergies among Human Medicine students at a private Peruvian university, using observational and retrospective methods.
- The research involved 355 students aged 18-25, revealing that 9.3% reported having a food allergy, with seafood and spices being the most common triggers.
- The findings suggest a notable prevalence of food allergies related to both native Peruvian products and those commonly consumed in the country.
Objective: To specify the association between atopic dermatitis and food allergies in students of Human Medicine in a private university in Lima-Peru.
Methods: An observational, analytical, cross-sectional study that included 355 students of human medicine between the ages of 18 and 25 years, of a private university in Lima-Peru, through a virtual survey. The data were analyzed using Fisher's technique, Student's T test, and Poisson regression.
Silver nanoparticles (AgNPs) are promising antibacterial nanomaterials for diagnostic and treatment of diabetes. However, toxicity and adverse cardiac responses induced by AgNPs related to nitric oxide (NO) and oxidative stress (OS) are described. Moreover, little is known about the diabetes influence upon AgNPs-toxicity.

- Adverse reactions to food have increased globally, with food allergies affecting 2-4% of adults and 6-8% of children, displaying a range of symptoms from mild to severe, necessitating allergen testing.
- The study aimed to profile patients with suspected food allergies in Mexico and analyzed data from 1,971 patients, revealing no gender differences but a bimodal age distribution with peaks at ages 2 and 35.
- Most patients had prior respiratory allergies, 80% experienced symptoms before consultation, and skin reactions were most common, with only 5% reporting anaphylaxis; thus, proper diagnostic confirmation is crucial despite high suspicion.
Background: Two different allergic rhinitis (AR) symptom phenotype classifications exist. Treatment recommendations are based on intermittent-persistent (INT-PER) cataloging, but clinical trials still use the former seasonal AR-perennial AR (SAR-PAR) classification. This study was designed to describe how INT-PER, mild-moderate/severe and SAR-PAR of patients seen by allergists are distributed over the different climate zones in a (sub)tropical country and how these phenotypes relate to allergen sensitization patterns.

We investigated whether sensitization patterns vary in a country with subtropical and tropical regions and if sensitization patterns relate to AR phenotypes or age.
Methods: In a national, cross-sectional study AR patients (2-70 y) seen by allergists underwent blinded skin prick testing with a panel of 18 allergens and completed a validated questionnaire on AR phenotypes.
Background: Evidence regarding the safety profile of drugs may vary depending on study sponsorship. We aimed to evaluate differences between studies funded by the pharmaceutical manufacturer of the drug (PF) and those with no pharmaceutical funding (NoPF) regarding the finding and interpretation of adverse effects of inhaled corticosteroids.
Methods: We assessed the safety reporting of inhaled corticosteroids in 275 PF and 229 NoPF studies identified by a MEDLINE search using prespecified criteria.
