Radiomics from Various Tumour Volume Sizes for Prognosis Prediction of Head and Neck Squamous Cell Carcinoma: A Voted Ensemble Machine Learning Approach.

Background: Traditionally, cancer prognosis was determined by tumours size, lymph node spread and presence of metastasis (TNM staging). Radiomics of tumour volume has recently been used for prognosis prediction. In the present study, we evaluated the effect of various sizes of tumour volume.

Occurrence of Potential Adverse Drug Events from Prescribing Errors in a Pediatric Intensive and High Dependency Unit in Hong Kong: An Observational Study.

Background: Critically ill pediatric patients are considered at high risk for medication errors. Although much research focuses on the actual errors, equally important are medication errors that, although intercepted, carried the potential for an adverse drug event. The aim of this study was to determine the occurrence of prescribing errors and potential adverse drug events (pADEs) in a local pediatric intensive and critical care unit (PICU) in Hong Kong.

Atmospheric deposition and fluxes of organochlorine pesticides and coplanar polychlorinated biphenyls in aquatic environments of Hong Kong, China.

Concentrations of organochlorine (OC) pesticides and coplanar (dioxin-like) polychlorinated biphenyls (PCBs) in bulk deposition were measured at the Mai Po Marshes Nature Reserve (MPMNR) and A Chau, which are both important habitats for waterbirds in Hong Kong. OC pesticides exempted from the Stockholm Convention were present in greater concentrations than those that have been restricted for use in the region. Among the OC pesticides, HCB, sigmaDDTs, and sigmaHCHs were detected.
