Background: Chronic cough affects around 10 % of the general adult population, impairing all aspects of quality of life.
Research Question: What are the Leicester Cough Questionnaire's psychometric properties?
Study Design And Methods: Electronic searches of PubMed, CINAHL, and ScienceDirect databases were conducted from inception until October 1rst 2022. All full-text articles, published in French or English, aimed at evaluating the LCQ's content validity or psychometric properties were included.
Coffee is one of the most widely consumed beverages. We performed a genome-wide association study (GWAS) of coffee intake in US-based 23andMe participants (N = 130,153) and identified 7 significant loci, with many replicating in three multi-ancestral cohorts. We examined genetic correlations and performed a phenome-wide association study across hundreds of biomarkers, health, and lifestyle traits, then compared our results to the largest available GWAS of coffee intake from the UK Biobank (UKB; N = 334,659).

- Obsessive-compulsive disorder (OCD) affects about 1% of people and has a strong genetic component, but previous studies have not fully explained its genetic causes or biological mechanisms.
- A large genome-wide association study (GWAS) analyzed data from over 53,000 OCD cases and over 2 million control participants, identifying 30 significant genetic markers related to OCD and suggesting a 6.7% heritability from SNPs.
- The research also found 249 candidate risk genes linked to OCD, particularly in specific brain regions, and showed genetic correlations with various psychiatric disorders, laying the groundwork for further studies and potential treatments.
Article Synopsis
- This study validates the medicinal use of Euphorbia calyptrata through testing its volatile compounds for therapeutic potential using advanced techniques like GC-MS/MS.
- The research demonstrated significant antioxidant capabilities and antimicrobial activity, with the essential oils showing effective inhibition against various bacterial and fungal strains.
- Phytochemical analysis identified key compounds, with molecular docking indicating strong interactions with specific targets, reinforcing the plant's effectiveness in traditional medicine.
Morocco is known for its high plant biodiversity, but many plants are poorly valorized. For this reason, this study aims to valorize the methanolic and aqueous extracts of leaves by studying their antioxidant activity and toxicity. The extracts' antioxidant activity is assessed using the FRAP, DPPH, CAT, and ABTS methods.
