The impact of antifungal prophylaxis in lung transplant recipients.
This study evaluated the effect of antifungal prophylaxis on all-cause mortality and invasive fungal infections (IFI) on lung transplant recipients. Administrative claims data was used to identify adult patients who underwent lung transplantation between 2005 and 2018. The authors identified 662 lung transplant recipients. All-cause mortality was found to be significantly lower in those receiving antifungal prophylaxis compared to those who did not. Patients receiving antifungal prophylaxis also had a lower rate of IFI, but it was not statistically significant.

A consensus approach to the primary prevention of food allergy through nutrition: guidance from the American Academy of Allergy, Asthma, and Immunology; American College of Allergy, Asthma, and Immunology; and the Canadian Society for Allergy and Clinical
This paper provides a consensus approach to the primary prevention of pediatric food allergy through nutrition using data from a number of high-impact randomized controlled trials. Recommendations from the American Academy of Allergy, Asthma, and Immunology, American College of Allergy, Asthma, and Immunology, and the Canadian Society for Allergy and Clinical Immunology are to introduce peanut and egg around age 6 months, but not before 4 months as well as introducing other allergens. Maternal exclusion of allergens during pregnancy and/or breastfeeding to prevent food allergy is not recommended. No association was found between exclusive breast-feeding and the primary prevention of any specific food allergy.

Masks for prevention of respiratory virus infections, including SARS-CoV-2, in health care and community settings : a living rapid review.
This study examined the effectiveness of N95, surgical, and cloth masks in community and health care settings for preventing respiratory virus infections, including coronavirus. The effects of reuse or extended use of N95 masks was also studied. The authors used multiple electronic databases, including the World Health Organization COVID-19 database and medRxiv preprint server (2003 through 2020), and reference lists. Randomized trials of masks and risks for respiratory virus infection were included. The studies were abstracted and methodological limitations were assessed by one reviewer, with a second reviewer providing verification. Thirty-nine studies with 33,867 participants were included. No studies were found that evaluated reuse or extended use of N95 masks. The studies showed that COVID-19 and MERS probably decreased with use versus nonuse and possibly decreased with N95 versus surgical mask use. Random trials in community settings found not much difference between N95 versus surgical masks. The studies’ findings were not definitive.

Mind the gaps: clinical trial concepts to address unanswered questions in aeroallergen immunotherapy-an NIAID/AHRQ workshop.
A joint AHRQ and National Institute of Allergy and Infectious Diseases (NIAAD) workshop was held to develop trial concepts that could improve the use and effectiveness of aeroallergen immunotherapy (AAIT). Four different expert groups were formed to propose different study designs. These study designs would create clinical trials of long duration and would need highly characterized patient populations.

Effectiveness of respiratory syncytial virus immunoprophylaxis in reducing bronchiolitis hospitalizations among high-risk infants.
This retrospective cohort study examined the effectiveness of respiratory syncytial virus (RSV) prophylaxis for infants born between 1996 and 2008. The infants were enrolled in the Kaiser Permanente Northern California integrated health system. Infants who ever received RSV immunoprophylaxis had a 32% decreased risk of bronchiolitis hospitalization and finants with chronic lung disease (CLD) had a 52% decreased risk. The 2014 American Academy of Pediatrics (AAP) guidelines changed recommendations for RSV immunoprophylaxis which made 48% of infants no longer eligible but nearly all infants with CLD would remain eligible.
