Following the “hygiene hypothesis” and the increase in the prevalence of atopic diseases such as allergic rhinitis, a plethora of studies have investigated the role of sibship composition as a protective factor, but findings are conflicting. The aim of this study was to synthesize the global literature linking birth order and sibship size (number o...

Obstructive sleep apnea (OSA) affects nearly one billion of the global adult population. It is associated with substantial burden in terms of quality of life, cognitive function, and cardiovascular health. Positive airway pressure (PAP) therapy, commonly considered the first-line treatment, is limited by low compliance and lacking efficacy on long-...

In 2014, the European Academy of Allergy and Clinical Immunology (EAACI) published the first systematic review that summarized the prevalence of food allergy (FA) and food sensitization in Europe for studies published 2000–2012. However, only summary estimates for tree nut allergy (TNA) were feasible in that work. In the current update of that syst...

Background Trajectories of asthma and allergy in children are heterogeneous and commonly derived from parental report of disease or clinical records. This study combined parental‐reported and register‐based dispensed medication data to characterize childhood trajectories of co‐existing asthma, allergic rhinitis, and eczema. Methods From a Swedish...

Background Fractional exhaled nitric oxide (FeNO) is used to differentiate asthma inflammatory phenotypes and guide its management. However, data on FeNO reference values in a representative adult population is limited. Objective To derive reference values and determinants of FeNO in a representative adult population. Methods The West Sweden Asthma...

Background The use of blood eosinophil count (BEC) as a prognostic biomarker in the management of conditions such as asthma and chronic obstructive pulmonary disease (COPD) may be complicated by factors like atopy, age, sex, smoking, and comorbidities. Therefore, we aimed to produce reference values for BEC, considering age, asthma, COPD, and clini...

Introduction Development of asthma and allergies in childhood/adolescence commonly follows a sequential progression termed the ‘atopic march’. Recent reports indicate, however, that these diseases are composed of multiple distinct phenotypes, with possibly differential trajectories. We aim to synthesise the current literature in the field of machin...

The clustering of categorical data is a common and important task in computer science, offering profound implications across a spectrum of applications. Unlike purely numerical datasets, categorical data often lack inherent ordering as in nominal data, or have varying levels of order as in ordinal data, thus requiring specialized methodologies for...

Adequate sleep duration has recently been recognized as a major determinant of cardiovascular health by the American Heart Association. This is a significant step toward recognizing sleep as a major lifestyle factor and pillar of health, along with physical activity and nutrition. However, healthy sleep is not only a matter of duration. Other dimen...

Background: Asthma is a heterogenous airway disease characterized by multiple phenotypes. Unbiased identification of these phenotypes is paramount for optimizing asthma management. Objectives: To identify and characterize asthma phenotypes based on a broad set of attributes using a novel machine learning approach in a representative sample of Swedi...

Background: The 2014 estimates of prevalence of food allergy (FA) in Europe published by the European Academy of Allergy and Clinical Immunology included only the eight so-called big foods (cow's milk/egg/wheat/soy/peanut/tree nuts/fish/shellfish). Those estimates have recently been updated. Complementing this, we sought to identify and estimate t...

In 2014, the European Academy of Allergy and Clinical Immunology published prevalence estimates for food allergy (FA) and food sensitization (FS) to the so‐called eight big food allergens (i.e. cow's milk, egg, wheat, soy, peanut, tree nuts, fish and shellfish) in Europe for studies published between 2000 and 2012. The current work provides 10‐year...

Background Atopic dermatitis and food allergy are two frequently concomitant manifestations of the presence of atopy. A substantial number of studies have been published on the association of birth order and sibship size (number of siblings) with atopic dermatitis, food allergy, and atopy. The present work is the first systematic synthesis of the e...

Background: Following the “hygiene hypothesis”, the role of sibship composition in asthma and wheezing has been extensively studied, but the findings are inconsistent. For the first time, this systematic review and meta-analysis synthesized evidences from studies investigating the association of sibship size and birth order with risk of asthma and...

Background: Due to the high transmissibility of SARS-CoV-2, accurate diagnosis is essential for effective infection control, but the gold standard, real-time reverse transcriptase-polymerase chain reaction (RT-PCR), is costly, slow, and test capacity has at times been insufficient. We compared the accuracy of clinician diagnosis of COVID-19 against...

Following the “hygiene hypothesis”, a plethora of studies have investigated the role of sibship composition in atopic diseases, but findings are largely conflicting. We undertook the first systematic review to synthesize the global literature linking birth order and sibship size to the risk of allergic rhinitis. Fifteen databases were searched from...

Food allergy (FA) is increasingly reported in Europe, however, the latest prevalence estimates were based on studies published a decade ago. The present work provides the most updated estimates of the prevalence and trends of FA in Europe. Databases were searched for studies published between 2012 and 2021, added to studies published up to 2012. In...

Background: Recent reports indicate that the prevalence of food allergy is increasing, but accurate estimates remain a challenge due to cross-reactivity and limited use of precise diagnostic methods. Molecular allergy diagnostics, in which sensitization to individual molecular allergens is measured, is emerging as a promising tool for evaluation o...

Recent reports indiciate that the prevelance of food allergy is increasing, but accurate estimates remain a challenge due to cross-reactivity and limited use of precise diagnostic methods. Component-resolved diagnostics (CRD), in which sensitization to individual molecular components of whole food allergen extracts is measured, is emerging as a pro...

Introduction The hygiene hypothesis suggests that reduced exposure to microbes might have contributed to the increase in prevalence and incidence of asthma and allergy observed during the second half of the last century. Following this proposal, several studies have investigated the role of sibship size and birth order in the development of asthma...
