ReviewAge-Related Differences in Immunological Responses to SARS-CoV-2.
There is a striking age-related disparity in the prevalence and severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 infections, which might be explained by age-dependent immunological mechanisms. These include age-related physiological differences in immunological responses, cross-neutralizing antibodies, and differences in levels and binding affinity of angiotensin-converting enzyme 2, the SARS-CoV-2 target receptor; antibody-dependent enhancement in adults manifesting with an overexuberant systemic inflammation in response to infection; and the increased likelihood of comorbidities in adults and the elderly. ⋯ Understanding the mechanisms through which pediatric patients are protected from severe novel coronaviruses infections will provide critical clues to the pathophysiology of coronavirus disease 2019 infection and inform future therapeutic and prophylactic interventions. Asymptomatic carriage in children may have major public health implications, which will have an impact on social and health care policies on screening and isolation practices, school reopening, and safe distancing requirements in the community.

ReviewClinician Wellness During the COVID-19 Pandemic: Extraordinary Times and Unusual Challenges for the Allergist/Immunologist.
The global spread of coronavirus disease 2019 (COVID-19) has caused sudden and dramatic societal changes. The allergy/immunology community has quickly responded by mobilizing practice adjustments and embracing new paradigms of care to protect patients and staff from severe acute respiratory syndrome coronavirus 2 exposure. Social distancing is key to slowing contagion but adds to complexity of care and increases isolation and anxiety. ⋯ Realizing early warning signs of anxiety, depression, substance abuse, and posttraumatic stress disorder is important to access safe and confidential resources. Implementing wellness strategies can improve flexibility, resilience, and outlook. Historical parallels demonstrate that perseverance is as inevitable as pandemics and that we need not navigate this unprecedented time alone.

ReviewDiagnosis and Management of Patients with the α-Gal Syndrome.
The galactose-α-1,3-galactose (α-Gal) syndrome has many novel features that are relevant to diagnosis and management. In most cases, the diagnosis can be made on a history of delayed allergic reactions to mammalian meat and the blood test for IgE to the oligosaccharide α-Gal. In general, the diagnosis also dictates the primary treatment, that is, avoiding mammalian meat and also dairy in some cases. ⋯ Some mammalian-derived products such as heart valves, gelatin-based plasma expanders, and pancreatic enzymes are relevant to only select patient groups. A minority of cases may benefit from avoiding a wide range of products that are prepared with mammalian-derived constituents, such as gelatin. This review focuses on the nature of the syndrome, common challenges in diagnosis and management, and also gaps in our current knowledge that would benefit from additional investigation.

The telemedicine industry and adoption of services have grown exponentially in the last 5 years, and the market is expected to reach more than $130 billion by 2025. Most US health institutions and hospital systems are currently using some form of telehealth, and more than 90% of health care executives surveyed across the United States have virtual care on their roadmap for growth. Telemedicine has been proposed as a way to expand the reach of allergy services and allow more patients to manage their disease with an allergy specialist. ⋯ Remote monitoring, specialist second opinions, and synchronous and asynchronous encounters offer opportunities to streamline routine care, especially as smart hardware such as digital inhalers hit the market and reimbursement for telehealth services evolve. To date, allergy care has been a significant area of interest for direct-to-consumer telemedicine solutions, although the care has mainly been offered by nonallergists. Quality assurance and adherence to evidence-based standards, particularly in the self-pay direct-to-consumer space, warrant attention.

Meta AnalysisCross-Reactivity to Cephalosporins and Carbapenems in Penicillin-Allergic Patients: Two Systematic Reviews and Meta-Analyses.
There is no recent systematic review on the risk of cross-reactivity to cephalosporins and carbapenems in penicillin-allergic patients despite many new studies on the subject. All past reviews have several limitations such as not including any patient with a T-cell-mediated penicillin allergy. ⋯ Although it remains possible that these meta-analyses overestimated the risk of cross-reactivity, clinicians should consider the increased risk of cross-reactivity associated with aminocephalosporins, and to a lesser extent with intermediate-similarity-score cephalosporins, compared with the very low risk associated with low-similarity-score cephalosporins and all carbapenems when using beta-lactams in patients with a suspected or proven penicillin allergy.
