Neural Processing of Odors with Different Well-Being Associations-Findings from Two Consecutive Neuroimaging Studies.

Much is known about the effect of odors on mood, cognition and behavior, but little is known about the relationship between odors and well-being. We investigated the neural processing of odors with different degrees of association with well-being (WB) through two large independent datasets. The study encompassed pre-testing and fMRI. During pre-testing, 100 and 80 (studies 1 and 2) young, healthy subjects participated, rating intensity, valence, and WB association for 14 (study 1) and 8 (study 2) different odors. Pre-testing resulted in the selection of two odors with high WB association (WB-associated) and two odors with lower WB association (neutral odors) for each study. Odors were delivered intranasally to the subjects who underwent fMRI scanning (44 and 41 subjects, respectively, for studies 1 and 2). We assessed brain activity for subjects when they experienced WB-associated versus neutral odors. In study 1, WB-associated odors showed increased activation in the right angular gyrus whereas in study 2, increased activity in the left angular gyrus existed, together with increased activity in the anterior cingulate cortex and posterior orbitofrontal cortex. The increased activity of higher-order cognitive and emotional regions during the processing of WB-associated odors in the two independent studies suggests a role of odors in influencing individual well-being. Moreover, the consistent activation of the angular gyrus might suggest its key role in shifting attention toward relevant emotional stimuli.

Chronic-Care-Management Programs for Multimorbid Patients with Diabetes in Europe: A Scoping Review with the Aim to Identify the Best Practice.

AIM: This scoping review is aimed at providing a current descriptive overview of care programs based on the chronic care model (CCM) according to E. H. Wagner. The evaluation is carried out within Europe and assesses the methodology and comparability of the studies. METHODS: A systematic search in the databases PubMed, Embase, and MEDLINE via OVID was conducted. In the beginning, 2309 articles were found and 48 full texts were examined, 19 of which were incorporated. Included were CCM-based programs from Belgium, Cyprus, Germany, Italy, Switzerland, and the Netherlands. All 19 articles were presented descriptively whereof 11 articles were finally evaluated in a checklist by Rothe et al. (2020). In this paper, the studies were tabulated and evaluated conforming to the same criteria. RESULTS: Due to the complexity of the CCM and the heterogeneity of the studies in terms of setting and implementation, a direct comparison proved difficult. Nevertheless, the review shows that CCM was successfully implemented in various care situations and also can be useful in single practices, which often dominate the primary care sector in many European health systems. The present review was able to provide a comprehensive overview of the current care situation of chronically ill patients with multimorbidities. CONCLUSIONS: A unified nomenclature concerning the distinction between disease management programs and CCM-based programs should be aimed for. Similarly, homogeneous quality standards and a Europe-wide evaluation strategy would be necessary to identify best practice models and to provide better care for the steadily growing number of chronically multimorbid patients.

Incidence of Diabetic Ketoacidosis of New-Onset Type 1 Diabetes in Children and Adolescents in Different Countries Correlates with Human Development Index (HDI): An Updated Systematic Review, Meta-Analysis, and Meta-Regression.

Type 1 diabetes mellitus (T1DM) is usually diagnosed by insulin deficiency at a young age. Diabetic ketoacidosis (DKA) represents a severe complication occurring before the first diagnosis of T1DM. Actually, the data situation is still unsettled in assessing the current state of diagnosis. This study summarizes the latest rates of DKA of new-onset T1DM in children and adolescents in different countries available over the last five years. Different T1DM-related, geographical and socioeconomic moderators are suitable to explain the heterogeneity of observed DKA rates. A systematic literature search using PubMed, EMBASE*, and MedLine* (*via OVID) was conducted to extract worldwide DKA rates covering publications from April 2011 to May 2016. We define DKA consistently by pH<7.3 or bicarbonate<15 mmol/l. We identified 34 suitable studies covering DKA rates in 25 countries. Overall DKA rates were compared to earlier studies to identify a temporal trend. We further applied a random effects meta-analysis and used meta-regression to reveal moderators of DKA rate heterogeneity. This review evaluating 34 studies includes 47 000 children and adolescents in total. DKA rates varied from 14.7% (Denmark) to 79.8% (Saudi Arabia). DKA rates are still high but a decline can also be recognized. The meta-regression shows that latitude (p<0.000) and human development index (HDI) (p<0.000) are moderators of DKA rates. The frequency of DKA rates occurrence varies widely for different countries. Both latitude and HDI partially explain the observed heterogeneity, while other moderators such as density of physicians showed no obvious correlation.
