Article Abstract

Traditionally, walnuts have occupied an imperative position in the functional food market with consistently recognized nutritious and functional properties. In the past years, the lipid profile of walnuts has brought much scientific attention via linking a cascade of biological attributes and health-promoting effects. Over time, researchers have focused on diversified composition (polyphenols and vitamins) of different parts of walnut (flower, pellicle, and kernel) and emphasized their physiological significance. Consequently, a plethora of reports has emerged on the potential role of walnut consumption against a series of diseases including cancer, gut dysbiosis, cardiovascular, and neurodegenerative diseases. Therefore, we accumulated the updated data on composition and classification, extraction methods, and utilization of different parts of walnuts as well as associated beneficial effects under in vivo and clinical studies. Altogether, this review summarized the ameliorative effects of a walnut-enriched diet in chronic diseases which can be designated to the synergistic or individual effects of walnut components mainly through anti-oxidative and anti-inflammatory role.

Background And Aims: We explored whether changes in serum proteomic profiles differed between participants with distinct brain aging trajectories, and whether these changes were influenced by dietary intervention.

Methods: In this secondary analysis of the 18-month DIRECT PLUS trial, 294 participants were randomized to one of three arms: 1) Healthy dietary guidelines (HDG); 2) Mediterranean (MED) diet (+440 mg/day polyphenols from walnuts); or 3) low red/processed meat green-MED diet (+1240 mg/day polyphenols from walnuts, Mankai plant, and green tea). We measured 87 serum proteins (Olink-CVDII).

Background: Tissue-based inguinal hernia repairs (IHRs), such as the Shouldice technique, are an acceptable alternative to mesh-based repairs in appropriately selected patients; however, they are often thought to be more painful than tension free repairs in the early postoperative period. We aimed to compare short-term pain and quality of life (QoL) between the Shouldice and Lichtenstein techniques for IHR.

Methods: The Abdominal Core Health Quality Collaborative (ACHQC) database was queried for patients who underwent open IHR between January 2017 and April 2023.
