Evaluation of a national programme to improve shared decision-making skills among junior medical doctors in Denmark: a mixed methods study of satisfaction, usefulness, and dissemination of learning outcomes in clinical practice.

BACKGROUND: Shared decision-making (SDM) is a cornerstone in patient-centred care and there has been an increase in programmes aiming to improve clinicians' abilities to engage in it. However, the evidence for such programmes' effectiveness on clinicians' use of SDM in clinical practice is sparse. The SDM Ambassador course, developed and facilitated by the Danish Association of Junior Doctors in Denmark (Junior Doctors Denmark) is a Danish SDM training programme for junior medical doctors (JMDs). This study aims to evaluate the SDM Ambassador course, with a focus on satisfaction, usefulness, and dissemination of learning outcomes in clinical practice. METHODS: This is a mixed methods study, consisting of an online survey followed by semi-structured interviews. The participants were JMDs who had trained to be SDM ambassadors between May 2016 and September 2020 (n=185). The ambassadors were invited to participate in the survey and 112 ambassadors completed it, corresponding to a response rate of 61%. Descriptive statistics and χ2-tests were conducted. Subsequently, purposive sampling was used to identify 10 ambassadors for interviews. The interviews were transcribed, encoded, and subsequently analysed thematically. Finally, the quantitative and qualitative results were integrated. RESULTS: Overall, the ambassadors were satisfied with their learning outcomes and experienced a greater capacity to unfold the perspectives of their patients. A majority (79%) reported that they had used SDM in their clinical practice with patients, and 59% had disseminated SDM to their colleagues. The usefulness and dissemination of learning outcomes in the clinic were shaped by the ambassadors' perceptions of their moderate professional experience as junior doctors, and constrained by structural and cultural conditions in the context of their clinical practice. CONCLUSIONS: Despite overall satisfaction with their learning outcomes, several ambassadors experienced conditions constraining the translation of their learning outcomes into clinical practice. To improve the efficacy of the training programme, continuous refresher courses should be added, while enhanced support at organisational and political levels is necessary for SDM to become an integral feature of the clinical encounter.

Bone morphogenetic protein 4 inhibits insulin secretion from rodent beta cells through regulation of calbindin1 expression and reduced voltage-dependent calcium currents.

AIMS/HYPOTHESIS: Type 2 diabetes is characterised by progressive loss of pancreatic beta cell mass and function. Therefore, it is of therapeutic interest to identify factors with the potential to improve beta cell proliferation and insulin secretion. Bone morphogenetic protein 4 (BMP4) expression is increased in diabetic animals and BMP4 reduces glucose-stimulated insulin secretion (GSIS). Here, we investigate the molecular mechanism behind this inhibition. METHODS: BMP4-mediated inhibition of GSIS was investigated in detail using single cell electrophysiological measurements and live cell Ca(2+) imaging. BMP4-mediated gene expression changes were investigated by microarray profiling, quantitative PCR and western blotting. RESULTS: Prolonged exposure to BMP4 reduced GSIS from rodent pancreatic islets. This inhibition was associated with decreased exocytosis due to a reduced Ca(2+) current through voltage-dependent Ca(2+) channels. To identify proteins involved in the inhibition of GSIS, we investigated global gene expression changes induced by BMP4 in neonatal rat pancreatic islets. Expression of the Ca(2+)-binding protein calbindin1 was significantly induced by BMP4. Overexpression of calbindin1 in primary islet cells reduced GSIS, and the effect of BMP4 on GSIS was lost in islets from calbindin1 (Calb1) knockout mice. CONCLUSIONS/INTERPRETATION: We found BMP4 treatment to markedly inhibit GSIS from rodent pancreatic islets in a calbindin1-dependent manner. Calbindin1 is suggested to mediate the effect of BMP4 by buffering Ca(2+) and decreasing Ca(2+) channel activity, resulting in diminished insulin exocytosis. Both BMP4 and calbindin1 are potential pharmacological targets for the treatment of beta cell dysfunction.

Microbial Safety and Sensory Analyses of Cold-Smoked Salmon Produced with Sodium-Reduced Mineral Salts and Organic Acid Salts.

Cold-smoked (CS) salmon contains high levels of sodium salts, and excess dietary sodium intake is associated with an array of health complications. CS salmon may also represent a food safety risk due to possible presence and growth of the foodborne pathogen Listeria monocytogenes which may cause fatal human infections. Here we determine how reformulated CS salmon using commercial sodium-reduced salt replacers containing KCl (e.g., Nutek, Smart Salt, SOLO-LITE) and acetate-based preservative salts (Provian K, proviant NDV) affect sensory properties, quality, and microbial safety. Initial sensory screening of sodium-reduced CS salmon was followed by L. monocytogenes growth analyses in selected variants of reformulated CS salmon, and finally by analyses of CS salmon variants produced in an industrial smokehouse. Projective mapping indicated overall minor sensory changes in sodium-replaced samples compared with a conventional product with NaCl. Growth of L. monocytogenes was temperature-dependent (4 °C vs. 8 °C storage) with similar growth in sodium-reduced and conventional CS salmon. The addition of 0.9% of the preservative salts Provian K or Provian NDV gave up to 4 log lower L. monocytogenes counts in both sodium-reduced and conventional cold-smoked salmon after 29 days of chilled storage. No changes in pH (range 6.20−6.33), aw levels (range 0.960−0.973), or weight yield (96.8 ± 0.2%) were evident in CS salmon with salt replacers or Provian preservative salts. Analyses of CS salmon produced with selected mineral salt and preservative salt combinations in an industrial salmon smokery indicated marginal differences in sensory properties. Samples with the preservative salt Provian NDV provided L. monocytogenes growth inhibition and low-level total viable counts (<2.8 log/g) dominated by Photobacterium and Carnobacterium during storage. Production of sodium-reduced CS salmon with inhibiting salts provides a simple method to achieve a healthier food product with increased food safety.
