Given the ubiquitous nature of love, numerous theories have been proposed to explain its existence. One such theory refers to love as a commitment device, suggesting that romantic love evolved to foster commitment between partners and enhance their reproductive success. In the present study, we investigated this hypothesis using a large-scale sample of 86,310 individual responses collected across 90 countries.

Background: Pathologic tissue remodeling with scarring and tissue rigidity has been demonstrated in inflammatory, autoimmune, and allergic diseases. Eosinophilic esophagitis (EoE) is an allergic disease that is diagnosed and managed by repeated biopsy procurement, allowing an understanding of tissue fibroblast dysfunction. While EoE-associated tissue remodeling causes clinical dysphagia, food impactions, esophageal rigidity, and strictures, molecular mechanisms driving these complications remain under investigation.

Introduction: Previous consensus-based long COVID research has focused on establishing research priorities, developing clinical definitions, core outcomes and a list of recommendations of patient-reported outcome measures that can be used to assess and characterise long COVID. Complementing and extending this work, the proposed study will bring together diverse knowledge users to prioritise concepts of care, quality of life and symptoms to inform a national patient registry on long COVID.

Methods And Analysis: We will conduct a Delphi process involving Canadians with lived experiences and/or professional expertise with long COVID (including clinicians, policymakers, caregivers and community leaders).

Article Synopsis
  • The introduction of immune checkpoint blockade (ICB) has greatly improved treatment outcomes for advanced melanoma, but many patients still become resistant to it due to unclear reasons.
  • Although combining different ICB therapies has been shown to enhance response rates, it also comes with increased toxicity for patients.
  • An analysis of tumor samples from ICB-naïve patients revealed that high genomic heterogeneity and low ploidy can identify those who are intrinsically resistant to aPD-1, leading to a predictive model that may help tailor treatment strategies.

Article Synopsis
  • NPIs significantly reduced asthma exacerbations and viral infections in pediatric patients during their enforcement from March 2020 to December 2022.
  • A total of 5,758 asthma exacerbations were recorded, with a 50% decline during NPIs, while 87% of the 70,682 respiratory tests returned positive for pathogens but showed decreased rates for some viruses.
  • After the NPIs ended, asthma exacerbations returned to pre-pandemic levels, and an unexpected spike in respiratory syncytial virus infections highlighted the importance of ongoing monitoring.
