Following children with severe or profound intellectual and multiple disabilities and their mothers through a communication intervention: single-case mixed-methods findings.

There is limited research targeting communication interventions for children with severe/profound intellectual and multiple disabilities. This study addressed outcomes from a communication course for parents of children with severe/profound intellectual and multiple disabilities and follows up on a previous publication by Rensfeldt Flink (2020). Potential observable changes in the children's and parents' communicative behavior were studied as well as the parents' experiences of the intervention process and the effect of the course on parent-child communication.

Analysis of nitrogen-based explosives with desorption atmospheric pressure photoionization mass spectrometry.

Rationale: Fast methods that allow the in situ analysis of explosives from a variety of surfaces are needed in crime scene investigations and home-land security. Here, the feasibility of the ambient mass spectrometry technique desorption atmospheric pressure photoionization (DAPPI) in the analysis of the most common nitrogen-based explosives is studied.

Methods: DAPPI and desorption electrospray ionization (DESI) were compared in the direct analysis of trinitrotoluene (TNT), trinitrophenol (picric acid), octogen (HMX), cyclonite (RDX), pentaerythritol tetranitrate (PETN), and nitroglycerin (NG).

Biomechanical evaluation of periprosthetic refractures following distal femur locking plate fixation.

Introduction: Distal femur fractures proximal to total knee femoral component constitutes the most prevalent type of periprosthetic fracture, and plate fixation treatment is associated with a 7.7% incidence of refracture proximal to the plate. The primary objective of this study was to compare proximal fixation techniques of a periprosthetic distal femur fracture plate in an osteoporotic bone model.

[Chronic pain conditions in foot and ankle region].

New starting points are available for the diagnosis, classification and treatment of prolonged pain conditions in the foot and ankle region. Mechanisms maintaining the pain should be clarified, and a comprehensive patient interview must be conducted. Physical examination shall include static observation, functional tests, passive movement tests as well as provocative and mapping tests.

Direct analysis of cannabis samples by desorption atmospheric pressure photoionization-mass spectrometry.

Fast analysis of cannabis samples without prior sample preparation or chromatography was performed using desorption atmospheric pressure photoionization-mass spectrometry (DAPPI-MS). The MS(2) spectra of the molecular ions of tetrahydrocannabinol (THC) and cannabidiol (CBD) formed in DAPPI-MS showed distinct product ions, unlike the protonated molecules formed with other ambient mass spectrometry techniques, making possible the reliable identification of THC from cannabis samples.
