Toxoplasma gondii infections are prevalent in humans and animals all over the world. The aim of the study was to estimate the occurrence of T. gondii oocysts in fruits and vegetables and determine the genotype of the parasites. A total number of 216 fruits and vegetables samples were taken from shops and home gardens located in the area of northern Poland. Oocysts were recovered with the flocculation method. Then, real-time polymerase chain reaction (PCR) targeting the B1 gene was used for specific T. gondii detection and quantification. Toxoplasma DNA was found in 21 samples. Genotyping at the SAG2 locus showed SAG2 type I and SAG2 type II. This is the first investigation describing T. gondii DNA identification in a large number of fruits and vegetables samples with rapid molecular detection methods. The results showed that fruits and vegetables contaminated with T. gondii may play a role in the prevalence of toxoplasmosis in Poland.

Exploring the textural characteristics of foods preferred by Chinese elderly individuals based on IDDSI levels.
PLoS One
January 2025
Department of Clinical Nutrition, West China Hospital, Sichuan University, Chengdu, China.
Objective: This study aimed to investigate the textural characteristics of foods preferred by elderly Chinese individuals and their suitability based on the International Dysphagia Diet Standardization Initiative (IDDSI) framework. The goal was to provide objective data to support the development of safe and nutritious diets tailored to the swallowing abilities of the elderly.
Methods: A cross-sectional observational study was conducted, using web-scraping technology to identify 26 commonly preferred food ingredients among elderly individuals across seven regions of China.
Food Insecurity Is Common in the Orthopaedic Trauma Population.
J Am Acad Orthop Surg
January 2025
From the Department of Orthopedics and Rehabilitation, University of Iowa Hospitals and Clinics, Iowa City, IA (Willey, Miller, Temperly, Martin, Leary, Marsh, and Glass), Slocum Research and Education Foundation, Eugene, OR (Owen, Fitzpatrick, and Kirkpatrick), the Department of Health Policy and Management, Johns Hopkins Bloomberg school of Public Health, Baltimore, MD (Reider), and the Department of Orthopedic Surgery, Vanderbilt University Medical Center, Nashville, TN (Trochez, Wrenn, and Ponce).
Introduction: Food insecurity is the condition of limited access to healthy and safe food. Malnutrition resulting from food insecurity is a concern particularly in the surgical population due to the association with impaired healing. This aim of this study was to report the incidence and risk factors for food insecurity in the orthopaedic trauma population.

Consumption of plant-based food is steadily increasing and follows an augmented trend owing to their nutritive, functional, and energy potential. Different bioactive fractions, such as phenols, flavanols, and so on, contribute highly to the nutritive profile of food and are known to have a sensitivity toward higher temperatures. This limits the applicability of traditional thermal treatments for plant products, paving the way for the advancement of innovative and non-thermal techniques such as pulsed electric field, microwave, ultrasound, cold plasma, and high-pressure processing.

Objective: To characterize food group consumption, assess the contribution of food groups to energy and micronutrient intake, and estimate usual nutrient intake among adults in rural Sri Lanka.
Design: A baseline survey (Dec 2020-Feb 2021) was conducted as part of an agriculture-based, nutrition-sensitive resilience program evaluation. Dietary intake was assessed using telephone-based 24-hour recalls (n=1283), with repeat recalls from 769 participants.
