TP53 Wild-type, HPV-independent Anal Growth/(intra)Epithelial Lesion (ANGEL): a Potential Precursor of Anal Squamous Cell Carcinoma.

Human papillomavirus (HPV) underpins approximately 90% of squamous cell carcinomas (SCC) of the anus and perianal region. These tumors usually arise in association with precursor lesions such anal intraepithelial neoplasia/ high-grade squamous intraepithelial lesion (AIN 3/ HSIL), whereas a small subset of HPV-negative cancers may harbor mutations in TP53. Recently, vulvar lesions termed differentiated exophytic vulvar intraepithelial lesion/vulvar acanthosis with altered differentiated (DEVIL/VAAD) have been recognized as HPV-independent, TP53 wild-type precursors for vulvar carcinoma; however, analogous anal lesions have not been described.

In Vitro and In Vivo Antioxidant and Immune Stimulation Activity of Wheat Product Extracts.

Background/objectives: Inflammation and oxidative stress are the main pathogenetic pathways involved in the development of several chronic degenerative diseases. Our study is aimed at assessing the antioxidant and anti-inflammatory activity of hydroalcoholic extracts obtained from wheat and its derivatives.

Methods: The content of total phenolic and total flavonoid compounds and antioxidant activity were carried out by ABTS and DPPH assays.

Unusual Manifestation of Vitamin K Deficiency, Nodular Purpura: A Case Series.

Vitamin K deficiency is a common entity in infancy characterized by bleeding from various sites, intracranial bleeding being the most commonly reported feature. Nodular purpura is an uncommon manifestation of vitamin K deficiency in infancy with a few reported cases in literature. We present four cases of infants presenting with nodular purpura as a manifestation of late-onset vitamin K deficiency bleeding (VKDB).

Exploring the barriers and enablers to the standardized and routine use of patient-rated outcomes for clients presenting with hand injuries at an Australian public hospital.

Background: The utilization of standardized patient-rated outcome measures (PROMs) by hand therapists is essential to evaluate treatment and clinical outcomes and underpins evidence-based and patient-centered practice. However, research indicates that the routine use of PROMs is inconsistent in clinical practice.

Purpose: To explore the barriers and enablers experienced by hand therapists in the routine use of standardized and valid PROMs.

Primary care in the COVID-19 pandemic and beyond: Lessons from Ontario.

Objective: To understand the role of primary care in the COVID-19 pandemic to provide insight into its functioning and inform potential reforms.

Composition Of The Committee: The now dissolved Ontario COVID-19 Science Advisory Table (Science Table) was formed in July 2020 to provide decision makers and the public with a synthesis of rapidly evolving evidence related to COVID-19. The Science Table was based at the Dalla Lana School of Public Health at the University of Toronto, and supported by Public Health Ontario.
