Objective: Previous studies have reported a correlation between coronavirus disease-2019 (COVID-19) and asthma. However, data on whether asthma constitutes a risk factor for COVID-19 and the prevalence of asthma in COVID-19 cases still remain scant. Here, we interrogated and analyzed the association between COVID-19 and asthma.
Methods: In this study, we systematically searched PubMed, Embase, and Web of Science databases for studies published between January 1 and August 28, 2020. We included studies that reported the epidemiological and clinical features of COVID-19 and its prevalence in asthma patients. We excluded reviews, animal trials, single case reports, small case series and studies evaluating other coronavirus-related illnesses. Raw data from the studies were pooled into a meta-analysis.
Results: We analyzed findings from 18 studies, including asthma patients with COVID-19. The pooled prevalence of asthma in COVID-19 cases was 0.08 (95% CI, 0.06-0.11), with an overall I of 99.07%, < 0.005. The data indicated that asthma did not increase the risk of developing severe COVID-19 (odds ratio [OR] 1.04 (95% CI, 0.75-1.46) = 0.28; I=20%). In addition, there was no significant difference in the incidence of asthma with age in COVID-19 infections [OR] 0.77(95% CI, 0.59-1.00) = 0.24; =29%).
Conclusion: Taken together, our data suggested that asthma is not a significant risk factor for the development of severe COVID-19.

The immune system plays fundamental roles in maintaining physiological homeostasis. With the increasing prevalence of obesity-a state characterized by chronic inflammation and systemic dyshomeostasis-there is growing scientific and clinical interest in understanding how obesity reshapes immune function. In this review, we propose that obesity is not merely an altered metabolic state but also a fundamentally altered immunological state.

Introduction: Allergic rhinitis is the specific inflammation against allergen by immune defense cells on the nasal mucosa, which can lead to chronic nasal symptoms such as sneezing, itching, runny nose, and nasal congestion. It is associated with high morbidity including sinusitis, asthma, otitis media, hypertrophied inferior turbinate, and nasal polyps. Despite its complications, it remains poorly recognized and tracked.

An important aspect of precision medicine focuses on characterizing diverse responses to treatment due to unique patient characteristics, also known as heterogeneous treatment effects (HTE) or individualized treatment effects (ITE), and identifying beneficial subgroups with enhanced treatment effects. Estimating HTE with right-censored data in observational studies remains challenging. In this paper, we propose a pseudo-ITE-based framework for analyzing HTE in survival data, which includes a group of meta-learners for estimating HTE, a variable importance metric for identifying predictive variables to HTE, and a data-adaptive procedure to select subgroups with enhanced treatment effects.

To reduce chronic school absenteeism and morbidity and mortality among school-aged children, the prompt administration of albuterol sulfate in schools remains vital. School-based stock inhaler programs are a practical approach to ensure equitable access to life-saving rescue medication for students. School and community partnerships can potentially strengthen program implementation and fidelity by integrating evidence-based practices into routine care.

Background: Food allergy has been shown to negatively impact children's mental health and quality of life. However, its impact on school performance is unknown.
Objective: We aimed to investigate whether food allergy, severe and nonsevere, is associated with school performance when accounting for measured and unmeasured familial factors.
