Factors associated with willingness to perform basic life support in the community setting in Yogyakarta, Indonesia.

Background: Cardiac arrest is one of the fatal medical emergencies which need to be treated immediately. Poor survival rates in the community settings are common because of limited and ineffective bystander basic life support (BLS). This study aimed to identify factors that are associated with the willingness to perform BLS in communities in Yogyakarta, Indonesia METHODS: A descriptive study was conducted with a cross-sectional design.

Enantiomeric quantification of (S)-(+)-methamphetamine in urine by an immunoaffinity column and liquid chromatography-electrospray-mass spectrometry.

A method using an immunoaffinity column (IAC) and liquid chromatography-electrospray ionization mass spectrometry (LC/MS) for on-line detecting the presence of MA in the effluent was developed for the quantitative and enantiomeric determination of (S)-(+)-methamphetamine (d-MA) in urine. The IAC was made in our laboratory and utilized in the LC/MS to simultaneously extract and separate enantiomers of MA from urine samples. An aqueous ammonium acetate buffer was used as the mobile phase.
