PRUDENT is anticipated to strengthen capacities for better oral care financing in the EU and worldwide.

Predictors of whole exome sequencing in dystonic cerebral palsy and cerebral palsy-like disorders

INTRODUCTION

Cerebral palsy (CP) is a group of permanent disorders attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. Cerebral palsy-like (CP-like) disorders may clinically resemble CP but do not fulfill CP criteria and have often a progressive course and/or neurodevelopmental regression. To assess which patients with dystonic CP and dystonic CP-like disorder should undergo Whole Exome Sequencing (WES), we compared the rate of likely causative variants in individuals regarding their clinical picture, co-morbidities, and environmental risk factors.

METHOD

Individuals with early onset neurodevelopmental disorder (ND) manifesting with dystonia as a core feature were divided into CP or CP-like cohorts based on their clinical picture and disease course. Detailed clinical picture, co-morbidities, and environmental risk factors including prematurity, asphyxia, SIRS, IRDS, and cerebral bleeding were evaluated.

RESULTS

A total of 122 patients were included and divided into the CP group with 70 subjects (30 males; mean age 18y5m±16y6m, mean GMFCS score 3.3 ± 1.4), and the CP-like group with 52 subjects (29 males; mean age 17y7m±1y,6 m, mean GMFCS score 2,6 ± 1,5). The WES-based diagnosis was present in 19 (27.1%) CP patients and 30 CP-like patients (57.7%) with genetic conditions overlap in both groups. We found significant differences in diagnostic rate in CP individuals with vs. without risk factors (13.9% vs. 43.3%); Fisher's exact p = 0.0065. We did not observe the same tendency in CP-like (45.5% vs 58.5%); Fisher's exact p = 0.5.

CONCLUSION

WES is a useful diagnostic method for patients with dystonic ND, regardless of their presentation as a CP or CP-like phenotype.

Oral Health Care in Europe: Financing, Access and Provision

With growing awareness of the large burden of oral diseases and how limited coverage affects both access and affordability, oral health policy has been receiving increased attention in recent years. This culminated in the adoption of the WHO resolution on Oral Health in 2021, which urges Member States to better integrate oral health into their universal health coverage and noncommunicable disease agendas. This study investigates major patterns and developments in oral health status, financing, coverage, access, and service provision of oral health care in 31 European countries. While most countries cover oral health care for vulnerable population groups, the level of statutory coverage varies widely across Europe resulting in different coverage and financing schemes for the adult population. On average, one third of dental care spending is borne by public sources and the remaining part is paid out-of-pocket or by voluntary health insurance. This has important ramifications for financial protection and access to care, leaving many dental problems untreated. Overall, unmet needs for dental care are higher than for other types of care and particularly affect low-income groups. Dental care is undergoing various structural changes. The number of dentists is increasing, and the composition of the health workforce is starting to change in many countries. Dental care is increasingly provided in group practices and by practices that are part of private equity firms. Although there are early signs of a shift towards more prevention of oral diseases, dental care overall remains focused on treatment. A lack of data affects all areas of oral health care and impede to inform policy-making on the underlying causes and the prevalence of oral disease, as well as the effectiveness of community preventive activities and oral health services.

Overview of innovative skill-mix changes in nursing across Europe

Background

Many countries in Europe and worldwide have implemented new professional for nurses or are in the process of implementation, yet, an overview of the evidence on skill-mix changes has been missing. This study has analysed skill-mix innovations in nursing, evidence on outcomes and lessons for implementation.

Methods

An overview of systematic reviews, following a protocol plus country case studies, as part of an international study. The literature search was performed in six databases, with search terms covering skill-mix whereby the nursing profession played a key role. Screening was performed by three researchers after high interrater reliability rates were achieved. Analyses were performed for the nursing professions, a typology of skill-mix changes (task-shifting and role expansion) and evidence on outcomes.

Results

A total of 42 systematic reviews were identified on nurses working in new roles. The roles varied considerably, ranging from nurse prescribing to advanced practice nursing and nurse-led clinics. Nurse-led chronic care programmes were frequently identified, with overall positive outcomes on several health outcomes, e.g., for patients with diabetes or cardiovascular diseases. Nurses were also working in advanced roles in health promotion and prevention, e.g., performing screening programmes, showing equivalent quality of care compared with doctors if adequately trained. Several skill-mix models to enhance care coordination and integration were identified, suggesting that when tailored to the needs of specific population groups, particularly for vulnerable groups, may improve health outcomes or access to services.

Conclusions

The roles of nurses are increasingly diversifying and expanding internationally. Sharing country experiences on how to effectively educate the workforce to be prepared for these new roles and ensure smooth integration is critical.

A case of novel DYT6 dystonia variant with serious complications after deep brain stimulation therapy: a case report

Background

DYT6 dystonia belongs to a group of isolated, genetically determined, generalized dystonia associated with mutations in the THAP1 gene.

Case presentation

We present the case of a young patient with DYT6 dystonia associated with a newly discovered c14G>A (p.Cys5Tyr) mutation in the THAP1 gene. We describe the clinical phenotype of this new mutation, effect of pallidal deep brain stimulation (DBS), which was accompanied by two rare postimplantation complications: an early intracerebral hemorrhage and delayed epileptic seizures. Among the published case reports of patients with DYT6 dystonia, the mentioned complications have not been described so far.

Conclusions

DBS in the case of DYT6 dystonia is a challenge to thoroughly consider possible therapeutic benefits and potential risks associated with surgery. Genetic heterogeneity of the disease may also play an important role in predicting the development of the clinical phenotype as well as the effect of treatment including DBS. Therefore, it is beneficial to analyze the genetic and clinical relationships of DYT6 dystonia.

Social Health Insurance country responses to the COVID-19 pandemic

Background

Pandemic response is largely also driven by organization and governance of health systems. In countries with social health insurance (SHI) systems, pluralism of actors and decentralisation may represent a particular challenge in crisis times.

Objectives

We aim to present a comprehensive analysis of the health system responses during the COVID-19 pandemic of eight SHI countries: Austria, Belgium, France, Germany, Luxembourg, the Netherlands, Slovenia and Switzerland. The question at the centre of the analysis is how SHI funds and defining characteristics of SHI systems have shaped pandemic response and which lessons to draw from the experiences of the first wave (spring to autumn 2020).

Results

Our analysis highlights key characteristics driving pandemic response common across SHI countries, particular the level of (de)centralization of responsibilities and providers and the role of SHI funds (compared to other actors). Five key themes emerged: governance, SHI fund sustainability, the role of GPs, surveillance strategies and (essential) health service provision. We found that SHI funds were not represented in crisis management teams during the pandemic in the majority of countries analysed. Responsibility partly shifted towards central government and away from the SHI funds.

Conclusions

Decentralization may pose significant challenges among local authorities with regard to the coordination of policies and information system flows. At the same time, decentralized pandemic management may be favourable as it supports bottom-up self-organization of ambulatory care providers. In fact, coordinated ambulatory care often helped avoid overburdening hospitals in the countries analysed.

Atypical presentations of DYT1 dystonia with acute craniocervical onset

DYT1 gene mutations lead to early-onset dystonia that begins with focal limb onset and spreads to other body regions within 5 years, with typical sparing of the oromandibular muscles. In the present study, we describe two patients with an unusual presentation of the disease.

Dental care in Europe: financing, coverage and provision

Background

In Europe, countries have adopted very different approaches to providing publicly subsidized dental insurance coverage. However, little attention has been paid on these variations in the coverage, financing and provision of oral health care and its implications. This cross-country Health Systems in Transition (HiT) Review aims to fill this gap in the field of comparison of oral health systems.

Methods

The comparative HiT draws on multiple data sources. It builds on detailed country information from national HiTs and other international sources (MISSOC, OECD/OBS country profiles). International databases (Eurostat, OECD, EHIS, EU-SILC) are used as main sources to compare available oral health related indicators. National and international policy documents and information by country experts complement this information. The HiT covers all EU members states and countries belonging to the EU's single market (UK, Iceland, Norway, Switzerland).

Results

In almost all countries, dental care is funded to a greater extent by private patient payments than other health care sectors. Overall, contribution of voluntary health insurances (VHI) to dental spending is low, while out-of-pocket spending is substantial in many countries leading to high levels of unmet needs for dental care for financial reasons, mainly for poor households. Comparison of coverage reveals that most countries commit to a minimum scope of basic dental care (emergency care, children), but there is large variation in terms of restriction of service packages ranging from countries with very limited, partial to comprehensive coverage.

Conclusions

Dental care has become a priority for European policy makers as countries extend statutory dental care coverage recognising the importance of prevention of oral diseases. However, there remain wide variations in the level of coverage resulting in differences of likelihood of dental care use.

An extended comparative analysis using vignettes of dental care coverage

Background

Virtually all European countries state to guarantee universal healthcare coverage to their citizens. However, there is evidence, although scarce, that dental care is a special case as coverage is very limited in some countries and there are major differences across national jurisdictions. This comparative study tries to better understand how dental care is covered in Europe and Canada through the use of five vignettes presenting dental services for specific patients.

Methods

Experts from each country were asked to state whether the following situations were covered by their statutory systems: a) scaling and polishing to remove plaque deposits and calculus for an adult; b) treatment for caries including fillings and root canal treatment for an adult; c) prosthetic rehabilitation for an elderly; d) fillings and repairs for a seven-year old girl with serious tooth decay; e) orthodontic treatment for a 13 old boy.

Results

Preliminary analysis of the vignettes from 10 countries show that there is a large variation between countries in who delivers dental care, how much it costs and who pays for it.

Conclusions

Full coverage of dental care is rare in Europe and the extent of coverage varies greatly across countries in Europe and also in comparison to Canada.

Time trends in the geographical distribution of physicians, nurses and midwives in Europe

Background

Data on the supply of health professionals show large variations in the health workforce density among European countries based on national-level data. However, little attention has been paid to the comparison of health professional density at the regional level. This study aimed to analyse the density of physicians, nurses and midwives at regional level, using a cross-country comparative design and examine time trends.

Methods

Descriptive analysis of Eurostat data on the rate of health professionals per population at national and regional levels (NUTS 2 regions) for 2017 and time trends (2005-2017) and comparison to population density. To improve the cross-country comparability of data a set of criteria was applied, resulting in 15 European countries covered on physicians and eight for nurses and midwives. Changes over time in the regional distribution were analysed, using percentage change and compound annual growth rate (CAGR).

Results

We found a 2.4-fold difference in the physician density between the highest and lowest density countries (Austria: 513, Poland 241.6 per 100.000) and a 3.5-fold difference among nurses (Denmark: 1702.5, Bulgaria: 483). Differences by regions across Europe were higher and varied up to 4.5-fold both for physicians and nurses/midwives and did not improve over time. Results show that in all countries physician density levels are highest in densely populated regions, with capitals and/or major cities, while density of nurses and midwives tends to be higher in less populated areas. Overall, physician rates grew at a faster rate than the density levels of nurses and midwives.

Conclusions

International data should not only cover supply indicators at national level, but routinely collect regional data on the number of health professionals to demonstrate regional differences in workforce supply and to improve monitoring and workforce planning at regional levels.

Key messages

Despite increases in the density levels of physicians, nurses and midwives, time trends over a ten-year period showed no improvement in the geographical distribution within countries. The study is the first of its kind to descriptively analyse geographical density levels and time trends among health professionals across a selection of European countries using Eurostat data.

Theory of rotational columnar structures of soft spheres

There is a growing interest in cylindrical structures of hard and soft particles. A promising new method to assemble such structures has recently been introduced by Lee et al. [Lee, Gizynski, and Grzybowski, Adv. Mater. 29, 1704274 (2017)ADVMEW0935-964810.1002/adma.201704274]. They used rapid rotations around a central axis to drive spheres of lower density than the surrounding fluid towards the axis. This resulted in different structures as the number of spheres is varied. Here, we present comprehensive analytic energy calculations for such self-assembled structures, based on a generic soft sphere model, from which we obtain a phase diagram. It displays interesting features, including peritectoid points. These analytic calculations are complemented by preliminary numerical simulations for finite sample sizes with soft spheres. A similar analytic approach could be used to study packings of spheres inside cylinders of fixed dimensions, but with a variation in the number of spheres.

Diagnostic exome sequencing in early-onset Parkinson's disease confirms VPS13C as a rare cause of autosomal-recessive Parkinson's disease

Parkinson's disease (PD) is a genetically heterogeneous disorder and new putative disease genes are discovered constantly. Therefore, whole-exome sequencing could be an efficient approach to genetic testing in PD. To evaluate its performance in early-onset sporadic PD, we performed diagnostic exome sequencing in 80 individuals with manifestation of PD symptoms at age 40 or earlier and a negative family history of PD. Variants in validated and candidate disease genes and risk factors for PD and atypical Parkinson syndromes were annotated, followed by further analysis for selected variants. We detected pathogenic variants in Mendelian genes in 6.25% of cases and high-impact risk factor variants in GBA in 5% of cases, resulting in overall maximum diagnostic yield of 11.25%. One individual was compound heterozygous for variants affecting canonical splice sites in VPS13C, confirming the causal role of protein-truncating variants in this gene linked to autosomal-recessive early-onset PD. Despite the low diagnostic yield of exome sequencing in sporadic early-onset PD, the confirmation of the recently discovered VPS13C gene highlights its advantage over using predefined gene panels.

Simulation and observation of line-slip structures in columnar structures of soft spheres

We present the computed phase diagram of columnar structures of soft spheres under pressure, of which the main feature is the appearance and disappearance of line slips, the shearing of adjacent spirals, as pressure is increased. A comparable experimental observation is made on a column of bubbles under forced drainage, clearly exhibiting the expected line slip.

Electronic discharge summaries in cross-border care in the European Union: How close are we to making it happen?

Introduction

The political drive for cross-border care within the European Union and an increasing focus on integrated care both have implications for electronic health records. The hospital discharge summary is a critical component of systems to ensure quality and continuity of care, and in a cross-border setting would particularly benefit from an electronic version. We have explored the extent to which European Union level policy and practice on electronic health records address issues pertinent to the development and implementation of electronic discharge summaries for patients treated outside their own country.

Methods

We approached the topic by analysing data from two different sources: European Union policy documents on topics relevant to electronic health records and deliverables of European Union-funded electronic health record-focused research and development projects. Elements pertinent to different aspects of interoperability – legal, semantic and technical – were extracted from both sources and their content compared to assess the degree of consistency between policy and implementation targets.

Results

We identified 25 policy documents and 14 European Union-funded projects. Our results show that European legislation is increasingly aligned with projects funded through European Union sources and substantial progress has been accomplished in achieving electronic communication across European health systems. Nevertheless, the achievement of a European level interoperable discharge summary is still a distant goal, while inadequate attention has been paid to the coordination of current discharge summary practices in Member States.

Discussion

If the harmonized European Union patient summary is also to function as an electronic discharge summary, further specific steps are needed that address issues of both content and processes related to communication.

The induction of α-helical structure in partially unfolded HypF-N does not affect its aggregation propensity

The conversion of proteins into structured fibrillar aggregates is a central problem in protein chemistry, biotechnology, biology and medicine. It is generally accepted that aggregation takes place from partially structured states of proteins. However, the role of the residual structure present in such conformational states is not yet understood. In particular, it is not yet clear as to whether the α-helical structure represents a productive or counteracting structural element for protein aggregation. We have addressed this issue by studying the aggregation of pH-unfolded HypF-N. It has previously been shown that the two native α-helices of HypF-N retain a partial α-helical structure in the pH-unfolded state and that these regions are also involved in the formation of the cross-β structure of the aggregates. We have introduced mutations in such stretches of the sequence, with the aim of increasing the α-helical structure in the key regions of the pH-unfolded state, while minimizing the changes of other factors known to influence protein aggregation, such as hydrophobicity, β-Sheet propensity, etc. The resulting HypF-N mutants have higher contents of α-helical structure at the site(s) of mutation in their pH-unfolded states, but such an increase does not correlate with a change of aggregation rate. The results suggest that stabilisation of α-helical structure in amyloidogenic regions of the sequence of highly dynamic states does not have remarkable effects on the rate of protein aggregation from such conformational states. Comparison with other protein systems indicate that the effect of increasing α-helical propensity can vary if the stabilised helices are in non-amyloidogenic stretches of initially unstructured peptides (accelerating effect), in amyloidogenic stretches of initially unstructured peptides (no effect) or in amyloidogenic stretches of initially stable helices (decelerating effect).

Outbreak of Streptococcus equi subsp. zooepidemicus infection in a group of rhesus monkeys (Macaca mulatta)

Background  A severe upper respiratory tract infection occurred in a breeding group of rhesus monkeys housed together in one of six indoor/outdoor corals of the German Primate Center. The clinical signs of the disease included severe purulent conjunctivitis, rhinitis, pharyngitis, respiratory distress and lethargy. Six of 45 animals died within a few days after developing signs of infection.

Methods and results  Histopathologic and microbiologic examinations of the dead animals were consistent with a severe fibrinopurulent bronchopneumonia. Microbiology revealed a Lancefield group C streptococcus identified as Streptococcus equi subsp. zooepidemicus as the causative agent of infection.

Conclusions  The infection was passed on from animal to animal but did not spread to the other five breeding groups nearby. Extensive diagnostic testing failed to reveal the consisting presence of copathogens in individual cases. A visitor with upper respiratory disease was suspected as source of infection.

Replication of restless legs syndrome loci in three European populations

BACKGROUND

Restless legs syndrome (RLS) is associated with common variants in three intronic and intergenic regions in MEIS1, BTBD9, and MAP2K5/LBXCOR1 on chromosomes 2p, 6p and 15q.

METHODS

Our study investigated these variants in 649 RLS patients and 1230 controls from the Czech Republic (290 cases and 450 controls), Austria (269 cases and 611 controls) and Finland (90 cases and 169 controls). Ten single nucleotide polymorphisms (SNPs) within the three genomic regions were selected according to the results of previous genome-wide scans. Samples were genotyped using Sequenom platforms.

RESULTS

We replicated associations for all loci in the combined samples set (rs2300478 in MEIS1, p = 1.26 x 10(-5), odds ratio (OR) = 1.47, rs3923809 in BTBD9, p = 4.11 x 10(-5), OR = 1.58 and rs6494696 in MAP2K5/LBXCOR1, p = 0.04764, OR = 1.27). Analysing only familial cases against all controls, all three loci were significantly associated. Using sporadic cases only, we could confirm the association only with BTBD9.

CONCLUSION

Our study shows that variants in these three loci confer consistent disease risks in patients of European descent. Among the known loci, BTBD9 seems to be the most consistent in its effect on RLS across populations and is also most independent of familial clustering.

Genetics of sleep and sleep disorders

Genetic factors affect sleep. Studies in twin pairs demonstrate that the strong hereditary influences on sleep architecture and some sleep disorders are transmitted through families. Evidence like this strongly suggests that sleep regulation receives significant influence from genetic factors. Although recent molecular technologies have revealed evidence that genetic traits or gene products trigger particular changes in sleep electroencephalogram activity, we are still far from finding candidate genes or multiple mutations responsible for individual sleep disorders. Sleep is a very complex phenotype. Genetic susceptibility and environmental factors should be also considered as contributors to sleep phenotype. The aim of this review is to present a current summary and future prospects for genetic studies on sleep and selected sleep-associated disorders.

Multiexponential decay autocorrelation function in dynamic light scattering in near-critical ternary liquid mixture

The dynamic structure factor of a ternary liquid mixture is calculated from the theory of thermodynamic fluctuations with the help of linearized hydrodynamic equations. The theoretical model allows evaluating and classifying the transport properties near a critical solution point of a ternary mixture. In the vicinity of the critical solution point, experimental dynamic light scattering measurements reveal two hydrodynamic relaxation modes with well-separated characteristic relaxation times. From the autocorrelation functions, we can determine two effective diffusivities D(1) and D(2). As theoretically predicted by a model developed in this work, one of these two modes can be associated with thermal diffusion and the other with mass diffusion. In the special case of an incompressible liquid mixture limit, D(1) and D(2) are decoupled, becoming thermodiffusion coefficient D(T) and mutual mass diffusion coefficient D(ij). A possible physical meaning of D(1) and D(2) for a ternary mixture is discussed.

RLS3: Fine-mapping of an autosomal dominant locus in a family with intrafamilial heterogeneity

A new locus for restless legs syndrome (RLS3) was identified on chromosome 9p24-22. The authors analyzed transmission disequilibrium tests (TDTs) and affecteds-only linkage analysis in one large family of Bavarian origin, taking into account age at onset. P values were 0.0054 for marker D9S1810 for TDT and 0.0009 for the affecteds-only linkage analysis, providing a confirmation of RLS3. This study narrows the region containing the autosomal dominant RLS3 locus to 11.1 cM (16.6 Mbp).
