Bakgrunn: Pasienter i sykehjem har et sammensatt og komplekst sykdomsbilde. Pasientsikkerhetsprogrammet anbefaler bruk av verktøy for å systematisere kliniske observasjoner og sikre felles strukturerte rapporter mellom helsepersonell.
Formål: Hensikten med denne intervensjonsstudien var å utforske sykepleiere i sykehjem sine erfaringer med og utbytte av ferdighetstrening og simulering som metoder for kompetanseutvikling.
Metode: Intervensjonen inneholdt en kombinasjon av undervisning, ferdighetstrening og simulering kombinert med bruk av systematiske verktøy. Studien har et kvalitativt forskningsdesign der fokusgruppeintervjuer er valgt som metode for datasamling. Utvalget besto av 10 sykepleiere fra ett sykehjem.
Resultat: Ifølge deltakerne ga opplæringsintervensjonen økt faglig bevissthet og bedre kontroll i krevende situasjoner. Systematiske verktøy bidro til bedre samarbeid og kommunikasjon. En forutsetning for bred implementering av ny praksis er videre ferdighetstrening, deling av kunnskap og at nødvendig utstyr er tilgjengelig.
Konklusjon: Sykepleiere i sykehjem opplever stort behov for økt kompetanse i kartlegging og behandlingen av komplekse kliniske symptombilder hos pasientene. Studien viser at ferdighetstrening og simulering kombinert med bruk av systematiske verktøy synes å øke deltakernes kliniske observasjonsferdigheter.

Abstract

In this systematic review and meta-analysis, we compared the spatial navigation performance of older adults with mild cognitive impairment (MCI), Alzheimer’s Disease (AD), and other dementias, using healthy older adults as controls. In addition, we evaluated the possible influence of the environment type (virtual and real), protocol (object- or environment-based), and the navigation mode (active and passive navigation) on spatial navigation task performance. In total, 1372 articles were identified and 24 studies were included in the meta-analysis. We found a large effect size on the spatial navigation performance of patients with cognitive decline (statistical mean difference (SMD) = 0.87, confidence interval (CI95%) = 0.62-1.09, p < 0.001), especially amnestic MCI (SMD = 1.10, CI95% = 0.71-1.49, p < 0.001) and patients with AD (SMD = 1.60, CI95% = 1.25-1.95, p < 0.001). However, the tasks did not identify mixed and vascular dementia (SMD = 0.92, CI95% = -0.33-2.18, p = 0.15 and SMD = 0.65, CI95% = -0.67-1.97, p = 0.33, respectively). Spatial navigation ability assessed using the Floor Maze Test showed the largest effect size in differentiating healthy older adults and patients with cognitive decline (SMD = 1.98,CI95% = 1.00-2.97, p < 0.001). In addition, tasks that require walking showed the greatest differences between the two groups. These results suggest that spatial navigation impairment is important, but disease-specific behavioral biomarker of the dementia pathology process that can be identified even in the early stages.

Background: There is a lack of tools for selecting patients with advanced lung cancer who benefit the most from systemic treatment. Patient-reported physical function (PRPF) has been identified as a prognostic factor in this setting, but little is known about the prognostic value in advanced non-small-cell lung cancer (NSCLC). The aim of this study was to investigate if measured physical performance was an independent or stronger prognostic factor than PRPF in patients with advanced NSCLC receiving platinum-doublet chemotherapy.
Methods: We analyzed patients from a randomized trial comparing immediate and delayed pemetrexed therapy in stage III/IV NSCLC (n = 232) who performed timed up and go (TUG) and 5 m walk test (5 mWT) and reported physical function on the EORTC QLQ-C30 before chemotherapy commenced.
Results: Overall, 208 patients performed TUG and 5 mWT and were included in the present study. Poor physical function was significantly associated with poor survival (TUG: HR 1.05, p < 0.01, 5 mWT: HR 1.05, p = 0.03, PRPF: 1.01, p < 0.01), but only PRPF remained an independent prognostic factor in multivariable analyses adjusting for baseline characteristics (HR 1.01, p = 0.03).
Conclusions: Patient-reported, but not measured, physical performance was an independent prognostic factor for survival in patients with advanced NSCLC receiving platinum-doublet chemotherapy.

Background: There is limited knowledge regarding the process of deprescribing psychotropic drugs to people with dementia (PwD) conducted by general practitioners (GP). We investigated the impact of a multicomponent intervention, emphasizing medication reviews, on psychotropic drugs and behavioral and psychological symptoms (BPSD) in home-dwelling PwD and quantified change in patient-GP communication evaluated by their informal caregivers.

Methods: LIVE@Home.Path is a stepped-wedge closed-cohort cluster randomized controlled trial for people with mild to moderate dementia aged ≥65 and their informal caregivers (dyads) in Norway. Complementary to health care as usual (control condition), municipal coordinators implemented the multicomponent LIVE intervention: Learning, Innovation, Volunteer support, and Empowerment (including medication review by the PwD’s regular GPs). Block-randomization was used to allocate dyads in three groups receiving the intervention sequentially in periods of 6 months duration. Prepandemic data from the first period is reported, resulting in a 1:2 intervention-to-control ratio. Primary outcome was change in psychotropic drug use. Secondary outcomes were changes in BPSD by Neuropsychiatric Inventory and Cornell Scale of Depression in Dementia and patient-GP communication by an adaption of the Clinical Global Impression of Change.

Results: Four hundred thirty-eight dyads were screened, 280 included, and 237 participated at 6 months (intervention group n=67; control condition n=170). At baseline, 63% used psychotropic medication regularly: antidementia drugs (47%), antidepressants (13%), hypnotics/sedatives (13%), antipsychotics (5%), and anxiolytics (2%). At 6 months, medication reviews were more frequently conducted in the intervention group compared to control (66% vs 42%, P=0.001). We found no differences regarding a change in drug use and BPSD. Patient-GP communication enhanced in the intervention group (mean score 0.95 [standard deviation 1.68] vs 0.41 [1.34], P=0.022). In the intervention group, control group, and overall sample, the informal caregivers of those who had their medications reviewed reported improved patient-GP communication compared to those who did not.

Conclusions: Change in psychotropic drug use and BPSD did not differ, even though patient-GP communication improved with medication reviews. Restricted psychotropic drug use among PwD likely reflects more judicious prescribing practices in recent years. Nevertheless, medication reviews could be cultivated to optimize pharmacologic treatment for this complex population.

Abstract

Overall progress in life expectancy (LE) depends increasingly on survival in older ages. The birth cohorts now reaching old age have experienced considerable educational expansion, which is a driving force for the social change and social inequality. Thus, this study examines changes in old age LE by educational attainment in the Nordic countries and aims to fnd out to what extent the change in national LEs is attributable to education-specifc mortality and the shifting educational composition. We used national register data comprising total 65+populations in Denmark, Finland, Norway and Sweden to create period life tables stratifed by fve-year age groups (65–90+), sex and educational attainment. Diference in LE between 2001 and 2015 was decomposed into the contributions of mortality changes within each educational group and changes in educational composition. Increasing LE at all ages and in all educational groups coincided with persistent and growing educational inequalities in all countries. Most of the gains in LE at age 65 could be attributed to decreased mortality (63–90%), especially among those with low education, the largest educational group in most countries. The proportion of the increase in LE attributable to improved education was 10–37%, with the highest contributions recorded for women in Norway and Sweden. The rising educational levels in the Nordic countries still carry potential for further gains in national LEs. However, the educational expansion has contributed to uneven gains in LE between education groups, which poses a risk for the future increase of inequalities in LE.

Key features

In the HUNT Study, all residents aged ≥20 years in the Nord-Trøndelag region, Norway, have been invited to repeated surveys since 1984-86. The study data may be linked to local and national health registries.

The HUNT4 survey in 2017-19 included 56 042 participants in Nord-Trøndelag and 107 711 participants in the neighbouring Sør-Trøndelag region.

The HUNT4 data enable more long-term follow-up, studies of life course health trajectories and within-family studies.

New measures include body composition analysis using bioelectrical impedance; a 1-week accelerometer recording; physical and cognitive testing in older adults; measurements of haemoglobin and blood cell counts, HbA1c and phosphatidylethanol; and genotyping.

Researchers can apply for HUNT data access from HUNT Research Centre if they have obtained project approval from the Regional Committee for Medical and Health Research Ethics, see www.ntnu.edu/hunt/data

Objective
To examine whether psychological symptoms and cognitive patterns are associated with self-reported pain and pain sensitization in people with hand osteoarthritis (OA).
Design
In the Nor-Hand study (n ​= ​300), people with hand OA self-reported psychological symptoms (Hospital Anxiety and Depression Scale), cognitive patterns (Pain catastrophizing Scale and Arthritis Self-Efficacy Scale) as well as their pain severity in hands, overall pain and multi-joint pain. Central pain sensitization was measured clinically by temporal summation and pressure pain threshold tests. We examined whether psychological symptoms and cognitive patterns were cross-sectionally associated with pain using linear regression. Beta coefficients (β) per one standard deviation of the independent variable were presented. Stratified analyses were performed in cases of significant interactions (p ​< ​0.10).
Results
Higher levels of anxiety, depressive symptoms and pain catastrophizing and low levels of self-efficacy were statistically significantly associated with higher levels of hand pain by Numeric Rating Scale (β ​= ​0.43, 0.48 and −0.57, respectively). Similar associations were found for overall pain, but not for measures of central pain sensitization. In stratified analyses, anxiety and depressive symptoms were more strongly related with pain in subgroups with younger age and higher comorbidity burden. Pain catastrophizing was more strongly related with pain in subgroups with younger age, overweight/obesity, higher comorbidity burden and poor sleep.
Conclusion
Psychological symptoms and cognitive patterns were associated with self-reported OA pain, especially in people with younger age, overweight/obesity, higher comorbidity burden and poor sleep. No associations were found for psychological symptoms and cognitive patterns with pain sensitization.

Abstract:

The discrepancy between chronological age and the apparent age of the brain based on neuroimaging data – the brain age delta – has emerged as a reliable marker of brain health. With an increasing wealth of data, approaches to tackle heterogeneity in data acquisition are vital. To this end, we compiled raw structural magnetic resonance images into one of the largest and most diverse datasets assembled (n=53542), and trained convolutional neural networks (CNNs) to predict age. We achieved state-of-the-art performance on unseen data from unknown scanners (n=2553), and showed that higher brain age delta is associated with diabetes, alcohol intake and smoking. Using transfer learning, the intermediate representations learned by our model complemented and partly outperformed brain age delta in predicting common brain disorders. Our work shows we can achieve generalizable and biologically plausible brain age predictions using CNNs trained on heterogeneous datasets, and transfer them to clinical use cases.
