Initiation of student participation in practice:An audio diary study of international clinical placements

Background: Differences in professional practice might hinder initiation of student participation during international placements, and thereby limit workplace learning. This study explores how healthcare students overcome differences in professional practice during initiation of international placements. Methods: Twelve first-year physiotherapy students recorded individual audio diaries during the first month of international clinical placement. Recordings were transcribed, anonymized, and analyzed following a template analysis approach. Team discussions focused on thematic interpretation of results. Results: Students described tackling differences in professional practice via ongoing negotiations of practice between them, local professionals, and peers. Three themes were identified as the focus of students’ orientation and adjustment efforts: professional practice, educational context, and individual approaches to learning. Healthcare students’ initiation during international placements involved a cyclical process of orientation and adjustment, supported by active participation, professional dialogue, and self-regulated learning strategies. Conclusions: Initiation of student participation during international placements can be supported by establishing a continuous dialogue between student and healthcare professionals. This dialogue helps align mutual expectations regarding scope of practice, and increase understanding of professional and educational practices. Better understanding, in turn, creates trust and favors meaningful students’ contribution to practice and patient care

Lessons learned spanning 17 years of experience with three consecutive nationwide competency based medical education training plans

IntroductionCurricula for postgraduate medical education have transformed since the introduction of competency based medical education (CBME). Postgraduate training plans offer broader training with different competencies and an outcome-based approach, in addition to the medical technical aspects of training. However, CBME also has its challenges. Over the past years, critical views have been shared on the potential drawbacks of CBME, such as assessment burden and conflicts with practicality in the workplace. Recent studies identified a need for a better understanding of how the evolving concept of CBME has been translated to curriculum design and implemented in the practice of postgraduate training. The aim of this study was to describe the development of CBME translations to curriculum design, based on three consecutive postgraduate training programs spanning 17 years.MethodWe performed a document analysis of three consecutive Dutch gynecology and obstetrics training plans that were implemented in 2005, 2013, and 2021. We used template analysis to identify changes over time.ResultsOver time, CBME-based curriculum design changed in several domains. Assessment changed from a model with a focus on summative decision to one with an emphasis on formative, low-stakes assessments aimed at supporting learning. The training plans evolved in parallel to evolving educational insights, e.g., by placing increasing emphasis on personal development. The curricula focused on a competency-based concept by introducing training modules and personalized authorization based on feedback rather than on a set duration of internships. There was increasing freedom in personalized training trajectories in the training plans, together with increasing trust towards the resident.ConclusionThe way CBME was translated into training plans has evolved in the course of 17 years of experience with CMBE-based education. The main areas of change were the structure of the training plans, which became increasingly open, the degree to which learning outcomes were mandatory or not, and the way these outcomes were assessed

Love thy neighbour?-Spatial variation in density dependence of nest survival in relation to predator community

Aim: In many species, density-dependent effects on reproduction are an important driver of population dynamics. However, it is rarely considered that the direction of density dependence is expected to vary over space and time depending on anti-predator behaviour and predator community. Aggregation may allow for effective group mobbing against avian nest predators while aggregation may also attract mammalian predators, causing negative density dependence. We aim to quantify spatial variation in the effect of conspecific breeding density on nest survival in a mobbing bird species (Eurasian oystercatcher; Haematopus ostralegus) and identify whether this variation in density dependence can be explained by the predator community. Location: Country-wide (The Netherlands). Methods: We integrated reproductive data with breeding territory maps of Eurasian oystercatchers and occupancy maps of avian and mammalian predator species across the Netherlands for a 10-year period. Results: Spatial variation in the composition of the predator community explained the effects of neighbour density, showing decreasing nest survival when both conspecific density and mammalian dominance increased. Also, heterospecific density (from breeding godwits and lapwing) has an additional effect on the oystercatcher nest survival. Strikingly, this pattern did not extend to mammal-free island populations. Main conclusions: Our study provides evidence that both the strength and sign of density dependence can vary spatially within species, implying that it is dangerous to generalize results from a single local population to large-scale management implications and modelling exercises. The study also suggests that conservation actions that aim to attract breeding birds should be prioritized in areas with fewer mammalian predators, but this idea requires further testing on island populations

Plasma glial fibrillary acidic protein is elevated in cognitively normal older adults at risk of Alzheimer’s disease

© 2021, The Author(s). Glial fibrillary acidic protein (GFAP), an astrocytic cytoskeletal protein, can be measured in blood samples, and has been associated with Alzheimer’s disease (AD). However, plasma GFAP has not been investigated in cognitively normal older adults at risk of AD, based on brain amyloid-β (Aβ) load. Cross-sectional analyses were carried out for plasma GFAP and plasma Aβ1–42/Aβ1–40 ratio, a blood-based marker associated with brain Aβ load, in participants (65–90 years) categorised into low (Aβ−, n = 63) and high (Aβ+, n = 33) brain Aβ load groups via Aβ positron emission tomography. Plasma GFAP, Aβ1–42, and Aβ1–40 were measured using the Single molecule array (Simoa) platform. Plasma GFAP levels were significantly higher (p \u3c 0.00001), and plasma Aβ1–42/Aβ1–40 ratios were significantly lower (p \u3c 0.005), in Aβ+ participants compared to Aβ− participants, adjusted for covariates age, sex, and apolipoprotein E-ε4 carriage. A receiver operating characteristic curve based on a logistic regression of the same covariates, the base model, distinguished Aβ+ from Aβ− (area under the curve, AUC = 0.78), but was outperformed when plasma GFAP was added to the base model (AUC = 0.91) and further improved with plasma Aβ1–42/Aβ1–40 ratio (AUC = 0.92). The current findings demonstrate that plasma GFAP levels are elevated in cognitively normal older adults at risk of AD. These observations suggest that astrocytic damage or activation begins from the pre-symptomatic stage of AD and is associated with brain Aβ load. Observations from the present study highlight the potential of plasma GFAP to contribute to a diagnostic blood biomarker panel (along with plasma Aβ1–42/Aβ1–40 ratios) for cognitively normal older adults at risk of AD

Samenwerken en zakendoen via het Internet

In de Internetwereld zien we een nieuwe paradigma ontstaan: de ‘retailer’. Ook al is niet helemaal duidelijk wie deze rol gaat invullen, duidelijk is wel dat eindgebruikers een éénduidige ingang wensen voor een scala aan diensten. Transparantie van, onder andere, kosten is hierbij gewenst. Een dienstenaanbieder wil zich ook niet langer zorgen hoeven maken over generieke functionaliteit zoals authenticiteit en autorisatie van gebruikers, transacties, ‘application hosting’, betaling, of andere zaken die de zogenoemde retailer voor hem kan oplossen. Zo’n retailer past in een dienst-, in plaats van productgerichte aanpak. Het retailer paradigma wordt ondersteund door technische ontwikkelingen rondom het ASP model, de programmeertaal Java, ‘interoperabiliteit’, component software (hergebruik) en ‘netwerkcomputers’. Gebaseerd op het bovenstaande paradigma heeft FRIENDS een geïntegreerd platform ontwikkeld dat ondersteuning biedt aan zowel eindgebruikers, als ontwikkelaars, als aanbieders van on-line gedistribueerde diensten

Factorial validity and internal consistency of the PRAFAB questionnaire in women with stress urinary incontinence

<p>Abstract</p> <p>Background</p> <p>To investigate the factor structure, dimensionality and construct validity of the (5-item) PRAFAB questionnaire score in women with stress urinary incontinence (stress UI).</p> <p>Methods</p> <p>A cross validation study design was used in a cohort of 279 patients who were randomly divided into Sample A or B. Sample A was used for preliminary exploratory factor analyses with promax rotation. Sample B provided an independent sample for confirming the premeditated and proposed factor structure and item retention. Internal consistency, item-total and subscale correlations were determined to assess the dimensionality. Construct validity was assessed by comparing factor-based scale means by clinical characteristics based on known relationships.</p> <p>Results</p> <p>Factor analyses resulted in a two-factor structure or subscales: items related to 'leakage severity' (protection, amount and frequency) and items related to its 'perceived symptom impact' or consequences of stress UI on the patient's life (adjustment and body (or self) image). The patterns of the factor loadings were fairly identical for both study samples. The two constructed subscales demonstrated adequate internal consistency with Cronbach's alphas in a range of 0.78 and 0.84 respectively. Scale scores differed by clinical characteristics according to the expectations and supported the construct validity of the scales.</p> <p>Conclusion</p> <p>The findings suggest a two-factorial structure of the PRAFAB questionnaire. Furthermore the results confirmed the internal consistency and construct validity as demonstrated in our previous study. The best description of the factorial structure of the PRAFAB questionnaire was given by a two-factor solution, measuring the stress UI leakage severity items and the perceived symptom impact items. Future research will be necessary to replicate these findings in different settings, type of UI and non-white women and men.</p

Elevated plasma sclerostin is associated with high brain amyloid-b load in cognitively normal older adults

Osteoporosis and Alzheimer’s disease (AD) mainly affect older individuals, and the possibility of an underlying link contributing to their shared epidemiological features has rarely been investigated. In the current study, we investigated the association between levels of plasma sclerostin (SOST), a protein primarily produced by bone, and brain amyloid-beta (A ) load, a pathological hallmark of AD. The study enrolled participants meeting a set of screening inclusion and exclusion criteria and were stratified into A − (n = 65) and A + (n = 35) according to their brain A load assessed using A -PET (positron emission tomography) imaging. Plasma SOST levels, apolipoprotein E gene (APOE) genotype and several putative AD blood-biomarkers including A 40, A 42, A 42/A 40, neurofilament light (NFL), glial fibrillary acidic protein (GFAP), total tau (t-tau) and phosphorylated tau (p-tau181 and p-tau231) were detected and compared. It was found that plasma SOST levels were significantly higher in the A + group (71.49 ± 25.00 pmol/L) compared with the A − group (56.51 ± 22.14 pmol/L) (P \u3c 0.01). Moreover, Spearman’s correlation analysis showed that plasma SOST concentrations were positively correlated with brain A load (ρ = 0.321, P = 0.001). Importantly, plasma SOST combined with A 42/A 40 ratio significantly increased the area under the curve (AUC) when compared with using A 42/A 40 ratio alone (AUC = 0.768 vs 0.669, P = 0.027). In conclusion, plasma SOST levels are elevated in cognitively unimpaired older adults at high risk of AD and SOST could complement existing plasma biomarkers to assist in the detection of preclinical AD

Plasma amyloid‐beta levels in a pre‐symptomatic dutch‐type hereditary cerebral amyloid angiopathy pedigree: A cross‐sectional and longitudinal investigation

Plasma amyloid‐beta (Aβ) has long been investigated as a blood biomarker candidate for Cerebral Amyloid Angiopathy (CAA), however previous findings have been inconsistent which could be attributed to the use of less sensitive assays. This study investigates plasma Aβ alterations between pre‐symptomatic Dutch‐type hereditary CAA (D‐CAA) mutation‐carriers (MC) and non-carriers (NC) using two Aβ measurement platforms. Seventeen pre‐symptomatic members of a D‐ CAA pedigree were assembled and followed up 3–4 years later (NC = 8;MC = 9). Plasma Aβ1‐40 and Aβ1‐42 were cross‐sectionally and longitudinally analysed at baseline (T1) and follow‐up (T2) and were found to be lower in MCs compared to NCs, cross‐sectionally after adjusting for covari-ates, at both T1(Aβ1‐40: p = 0.001; Aβ1‐42: p = 0.0004) and T2 (Aβ1‐40: p = 0.001; Aβ1‐42: p = 0.016) employing the Single Molecule Array (Simoa) platform, however no significant differences were observed using the xMAP platform. Further, pairwise longitudinal analyses of plasma Aβ1‐40 revealed decreased levels in MCs using data from the Simoa platform (p = 0.041) and pairwise longitudinal analyses of plasma Aβ1‐42 revealed decreased levels in MCs using data from the xMAP platform (p = 0.041). Findings from the Simoa platform suggest that plasma Aβ may add value to a panel of biomarkers for the diagnosis of pre‐symptomatic CAA, however, further validation studies in larger sample sets are required

Consensus guidelines for lumbar puncture in patients with neurological diseases

Introduction Cerebrospinal fluid collection by lumbar puncture (LP) is performed in the diagnostic workup of several neurological brain diseases. Reluctance to perform the procedure is among others due to a lack of standards and guidelines to minimize the risk of complications, such as post-LP headache or back pain. Methods We provide consensus guidelines for the LP procedure to minimize the risk of complications. The recommendations are based on (1) data from a large multicenter LP feasibility study (evidence level II-2), (2) systematic literature review on LP needle characteristics and post-LP complications (evidence level II-2), (3) discussion of best practice within the Joint Programme Neurodegenerative Disease Research Biomarkers for Alzheimer's disease and Parkinson's Disease and Biomarkers for Multiple Sclerosis consortia (evidence level III). Results Our consensus guidelines address contraindications, as well as patient-related and procedure-related risk factors that can influence the development of post-LP complications. Discussion When an LP is performed correctly, the procedure is well tolerated and accepted with a low complication rate
