Outbreak investigations of and frozen raw breaded chicken: the mitigation of a significant public health issue in Canada.

In May 2017, whole-genome sequencing (WGS) became the primary subtyping method for in Canada. As a result of the increased discriminatory power provided by WGS, 16 multi-jurisdictional outbreaks of associated with frozen raw breaded chicken products were identified between 2017 and 2019. The majority (15/16) were associated with , while the remaining outbreak was associated with Heidelberg.

Plasma Aβ/Aβ is sensitive to early cerebral amyloid accumulation and predicts risk of cognitive decline across the Alzheimer's disease spectrum.

Introduction: The availability of amyloid beta (Aβ) targeting therapies for Alzheimer's disease (AD) is increasing the demand for scalable biomarkers that are sensitive to early cerebral Aβ accumulation.

Methods: We evaluated fully-automated Lumipulse plasma Aβ/Aβ immunoassays for detecting cerebral Aβ in 457 clinically unimpaired (CU) and clinically impaired (CI) Stanford Alzheimer's Disease Research Center (Stanford ADRC) participants and 186 CU in the Stanford Aging and Memory Study (SAMS). Longitudinal change in ADRC plasma Aβ/Aβ and cognition and cross-sectional associations with SAMS memory and tau positron emission tomography (PET) were examined.

A novel AI model for detecting periapical lesion on CBCT: CBCT-SAM.

Objectives: Periapical lesions are not always evident on radiographic scans. Sometimes, asymptomatic or initial periapical lesions on cone-beam computed tomography (CBCT) could be missed by inexperienced dentists, especially when the scan has a large field of view and is not for endodontic treatment purposes. Previously, numerous algorithms have been introduced to assist radiographic assessment and diagnosis in the field of endodontics.

TRPS1 Immunohistochemistry in Salivary Gland Neoplasms: Analysis on Cytology Cell Blocks and Surgical Follow-Up Correlation.

Introduction: In this study we aim to analyze the TRPS1 immunostaining of salivary gland tumors (SGT) on cytology cell blocks and compare the staining pattern on subsequent surgical resections.

Methods: Malignant SGTs, oncocytomas and basal cell adenomas diagnosed on fine needle aspiration were retrieved from 2019 to 2021 database. Cases with surgical follow-up were selected.

Swimming benefits outweigh risks of exposure to disinfection byproducts in pools.

Disinfection of swimming pool water is critical to ensure the safety of the recreational activity for swimmers. However, swimming pools have a constant loading of organic matter from input water and anthropogenic contamination, leading to elevated levels of disinfection byproducts (DBPs). Epidemiological studies have associated increased risks of adverse health effects with frequent exposure to DBPs in swimming pools.
