Summary: Dried blood spot (DBS) sampling has become the preferred method for newborn screening and therapeutic drug monitoring worldwide. It requires only a small amount of blood and has advantages such as simple collection, low sample storage costs, and microbial deactivation. However, DBS sampling is rarely used in forensic toxicological analyses.

Summary: An LC-MS/MS method was developed and validated for the analysis of vortioxetine in postmortem samples. The method showed acceptable sensitivity, selectivity, linearity, precision, and accuracy in various matrices. The concentrations of vortioxetine found in the authentic case may provide insight into similar cases in the future.

Summary: Oral antidiabetics are drugs used to control blood sugar in diabetic subjects. The greatest risk of using these drugs is hypoglycemia, especially in individuals with no history of exposure to these medications. Hair testing for oral antidiabetics can help differentiate the cause of hypoglycemia and has a large detection window with long-term stability. A liquid-chromatography coupled to tandem mass spectrometry method has been developed and successfully applied to analyze 13 oral antidiabetics in hair samples from diabetic patients.

Summary: An enantioselective method was developed to quantify amphetamine-type chiral illicit drugs in wastewater and surface water samples from a wastewater treatment plant and its effluent-receiving river in Beijing, China. The method showed excellent performance in monitoring the variations of enantiomers in the wastewater treatment process.

Summary: Passive smoking is a concern due to its harmful health risks. We developed a passive sampler coupled with perforated covers to improve sampling accuracy. Furthermore, a highly sensitive nicotine analysis method was developed. The results showed that the developed passive sampler and analytical method are promising tools for monitoring nicotine.

Summary: The study aimed to monitor adherence to antihypertensive medication by developing a quantification procedure for drug concentrations in blood plasma. Results showed that plasma concentration interpretation is more complex than urine screening but can effectively assess adherence. Further data is needed to determine if plasma quantification is superior in assessing adherence to antihypertensive medication.

Summary: The application of therapeutic proteins in pharmaceuticals is expanding, and efficient bioanalytical methods are crucial for their identification and clinical development. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is often used for quantitative protein analysis in complex samples due to its sensitivity, specificity, and throughput. Proper sample preparation is important to minimize interference and enhance the accuracy of LC-MS/MS assays.

Summary: The data reveals that cannabis is the most commonly seized illicit substance in the Arabian Gulf region, while methamphetamine is the most abused illicit drug in Kuwait. Deaths resulting from heroin and benzodiazepine abuse were the highest, with heroin-benzodiazepine combination deaths being most frequent. The lack of information regarding illicit substances in Kuwait highlights the need for further research and enforcement efforts.

Summary: Metabotyping using sweat from fingertips is a promising noninvasive tool for precision medicine, overcoming limitations of traditional metabolic analysis. Dynamic metabolic patterns can be assessed through sweat sampling, which is repeatable and reliable, enabling the monitoring of individual response to stimuli.

Summary: 3DMolMS is a deep neural network model that predicts mass spectra from the 3D conformations of compounds. It achieved an average cosine similarity of 0.691 and 0.478 with experimental MS/MS spectra in positive and negative ion modes, respectively. The model can be fine-tuned to predict spectra acquired by different labs and instruments. Additionally, the molecular representation learned by 3DMolMS can enhance the prediction of chemical properties such as elution time and collisional cross section.
