Hypothalamic VMHdm neurons are activated by predator cues and are necessary and sufficient for instinctive defensive responses. However, such data do not distinguish which features of a predator encounter are encoded by VMHdm neural activity. To address this issue, we imaged VMHdm neurons at single-cell resolution in freely behaving mice exposed to a natural predator in varying contexts.

Background: Individual kidney tubule biomarkers are associated with risks for chronic kidney disease (CKD) progression and mortality in persons with diabetes. Integrating multiple kidney biomarkers using a latent variable method of exploratory factor analysis could define distinct dimensions of kidney health, and their associations with adverse outcomes.

Methods: We conducted a factor analysis of 17 candidate urine and plasma biomarkers in 1,256 participants with diabetes and estimated glomerular filtration rate (eGFR) <60ml/min/1.

Introduction: BNT162b2 immunogenicity wanes with time and we investigated association between gut microbiota and longer-term immunogenicity.

Methods: This cohort study prospectively recruited adult BNT162b2 two-dose recipients from three vaccination centers in Hong Kong. Blood samples were collected at baseline and day 180 after first dose, and tested for neutralizing antibodies (NAb) against receptor-binding domain (RBD) of wild type SARS-CoV-2 virus using chemiluminescence immunoassay.

Purpose: Alternating electric fields (AEF) therapy in addition to temozolomide chemoradiotherapy (TMZ CRT) is increasingly being recommended as first-line treatment for patients with newly-diagnosed WHO grade 4 astrocytoma. However, few have validated this treatment with real-world evidence.

Methods: Consecutive adult patients with newly-diagnosed WHO grade 4 astrocytoma treated with adjuvant TMZ CRT across all neuro-oncology centers in Hong Kong were reviewed.

Purpose: Contracture is stiffness and reduction in how much a joint and muscle can move and may impact on self-care and functional ability. We outline the development of the first comprehensive Logic-Model of the problem for contracture development, to inform prevention and treatment.

Method: The initial Logic-Model was developed based on the literature by the research team.
