Purpose: Increasing life expectancy and advances in cancer treatment will lead to more patients needing both radiation therapy (RT) and cardiac implantable electronic devices (CIEDs). CIEDs, including pacemakers and defibrillators, are essential for managing cardiac arrhythmias and heart failure. Telemetric monitoring of CIEDs checks battery status, lead function, settings, and diagnostic data, thereby identifying software deviations or damage.

- Fluorinated organic compounds (FOCs) are durable synthetic chemicals with strong carbon-fluorine bonds that resist environmental breakdown, raising concerns about their ecological impact, especially in lithium-ion batteries (LiBs).
- The study examines two specific fluorinated compounds, tris(pentafluorophenyl)borane (TPFPB) and tris(pentafluorophenyl)phosphine (TPFPP), using various laboratory techniques to assess their transformation and degradation in the environment.
- Results showed that TPFPB produced a large number of harmful transformation products, including toxic dioxins, while TPFPP degraded only under severe conditions, suggesting that the use of FOCs in LiBs poses significant environmental risks
Polyphosphate (polyP) is an intriguing molecule that is found in almost any organism, covering a multitude of cellular functions. In industry, polyP is used due to its unique physiochemical properties, including pH buffering, water binding, and bacteriostatic activities. Despite the importance of polyP, its analytics is still challenging, with the gold standard being P NMR.

- Aging can lead to health problems, so it's important to find healthy eating habits that help us age well.
- The study looked at how two different eating patterns affected the mineral levels in older people between 50-80 years old over two years.
- Results showed both eating patterns initially had low zinc and selenium, but while zinc levels went down over time, levels of selenium, manganese, and magnesium increased in some participants.
Ergot alkaloids (EAs) formed by fungi are one of the most common food contaminants worldwide, affecting cereals such as rye, wheat, and barley. To accurately determine the level of contamination and to monitor EAs maximum levels set by the European Union, the six most common EAs (so-called priority EAs) and their corresponding epimers are quantified using high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The quantification of EAs in complex food matrices without appropriate internal standards is challenging but currently carried out in the standard method EN 17425:2021 due to their commercial unavailability.
