Diabetes management in a Primary Care Network (PCN) of private general practitioners in Singapore: An observational study.

A Primary Care Network (PCN) is a virtual network of general practitioners (GPs), sharing common resources and common clinical governance framework for effective chronic disease management. In this study, we analyzed the frequency of assessment as well as control of HbA1c, blood pressure (BP), and low-density lipoprotein (LDL) over time among adult patients with diabetes managed by a group of private GPs under PCN.Data, including clinical measurements of HbA1c, BP, and LDL from 2012 to 2015, of 943 subjects at 9 GP clinics that piloted PCN in Singapore in 2012 was obtained from the chronic disease register for this analysis.

Human health risk assessment based on trace metals in suspended air particulates, surface dust, and floor dust from e-waste recycling workshops in Hong Kong, China.

This study investigated health risks exerted on electronic waste (e-waste) recycling workers exposed to cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), mercury (Hg), and zinc (Zn) in Hong Kong. E-waste recycling workshops were classified into eight working areas: 1 = office, 2 = repair, 3 = dismantling, 4 = storage, 5 = desoldering, 6 = loading, 7 = cable shredding, and 8 = chemical waste. The aforementioned metal concentrations were analyzed in suspended air particulates, surface dust and floor dust collected from the above study areas in five workshops.

Cancer risk assessments of Hong Kong soils contaminated by polycyclic aromatic hydrocarbons.

The aim of this study was to evaluate soils from 12 different land use types on human cancer risks, with the main focus being on human cancer risks related to polycyclic aromatic hydrocarbons (PAHs). Fifty-five locations were selected to represent 12 different types of land use (electronic waste dismantling workshop (EW (DW)); open burning site (OBS); car dismantling workshop (CDW) etc.).

A material flow analysis on current electrical and electronic waste disposal from Hong Kong households.

A material flow study on five types of household electrical and electronic equipment, namely television, washing machine, air conditioner, refrigerator and personal computer (TWARC) was conducted to assist the Government of Hong Kong to establish an e-waste take-back system. This study is the first systematic attempt on identifying key TWARC waste disposal outlets and trade practices of key parties involved in Hong Kong. Results from two questionnaire surveys, on local households and private e-waste traders, were used to establish the material flow of household TWARC waste.
