Abstract
PURPOSE A new high-resolution next-generation sequencing (NGS)-based method was established to type closely related European type II Toxoplasma gondii strains. METHODS T. gondii field isolates were collected from different parts of Europe and assessed by whole genome sequencing (WGS). In comparison to ME49 (a type II reference strain), highly polymorphic regions (HPRs) were identified, showing a considerable number of single nucleotide polymorphisms (SNPs). After confirmation by Sanger sequencing, 18 HPRs were used to design a primer panel for multiplex PCR to establish a multilocus Ion AmpliSeq typing method. Toxoplasma gondii isolates and T. gondii present in clinical samples were typed with the new method. The sensitivity of the method was tested with serially diluted reference DNA samples. RESULTS Among type II specimens, the method could differentiate the same number of haplotypes as the reference standard, microsatellite (MS) typing. Passages of the same isolates and specimens originating from abortion outbreaks were identified as identical. In addition, seven different genotypes, two atypical and two recombinant specimens were clearly distinguished from each other by the method. Furthermore, almost all SNPs detected by the Ion AmpliSeq method corresponded to those expected based on WGS. By testing serially diluted DNA samples, the method exhibited a similar analytical sensitivity as MS typing. CONCLUSION The new method can distinguish different T. gondii genotypes and detect intra-genotype variability among European type II T. gondii strains. Furthermore, with WGS data additional target regions can be added to the method to potentially increase typing resolution.

Abstract
Tick-borne diseases (TBDs) have become a significant public health concern in the United States over the past few decades. The increasing incidence and geographical spread of these diseases have prompted the implementation of robust surveillance systems to monitor their prevalence, distribution, and impact on human health. This comprehensive review describes key disease features with the geographical distribution of all known tick-borne pathogens in the United States, along with examining disease surveillance efforts, focusing on strategies, challenges, and advancements. Surveillance methods include passive and active surveillance, laboratory-based surveillance, sentinel surveillance, and a One Health approach. Key surveillance systems, such as the National Notifiable Diseases Surveillance System (NNDSS), TickNET, and the Tick-Borne Disease Laboratory Network (TBDLN), are discussed. Data collection and reporting challenges, such as underreporting and misdiagnosis, are highlighted. The review addresses challenges, including lack of standardization, surveillance in non-human hosts, and data integration. Innovations encompass molecular techniques, syndromic surveillance, and tick surveillance programs. Implications for public health cover prevention strategies, early detection, treatment, and public education. Future directions emphasize enhanced surveillance networks, integrated vector management, research priorities, and policy implications. This review enhances understanding of TBD surveillance, aiding in informed decision-making for effective disease prevention and control. By understanding the current surveillance landscape, public health officials, researchers, and policymakers can make informed decisions to mitigate the burden of (TBDs).

Abstract
Collective spin excitations in magnetically ordered crystals, called magnons or spin waves, can serve as carriers in novel spintronic devices with ultralow energy consumption. The generation of well-detectable spin flows requires long lifetimes of high-frequency magnons. In general, the lifetime of spin waves in a metal is substantially reduced due to a strong coupling of magnons to the Stoner continuum. This makes metals unattractive for use as components for magnonic devices. Here, we present the metallic antiferromagnet CeCo2P2, which exhibits long-living magnons even in the terahertz (THz) regime. For CeCo2P2, our first-principle calculations predict a suppression of low-energy spin-flip Stoner excitations, which is verified by resonant inelastic X-ray scattering measurements. By comparison to the isostructural compound LaCo2P2, we show how small structural changes can dramatically alter the electronic structure around the Fermi level leading to the classical picture of the strongly damped magnons intrinsic to metallic systems. Our results not only demonstrate that long-lived magnons in the THz regime can exist in bulk metallic systems, but they also open a path for an efficient search for metallic magnetic systems in which undamped THz magnons can be excited.

Abstract
Dental caries lesions are a clinical manifestation of disease, preceded by microbial dysbiosis, which is poorly characterized and thought to be associated with saccharolytic taxa. Here, we assessed the associations between the oral microbiome of children and various caries risk factors such as demographics and behavioral and clinical data across early childhood and characterized over time the salivary and dental plaque microbiome of children before clinical diagnosis of caries lesions. Children (N = 266) were examined clinically at ~1, 2.5, 4, and 6.5 y of age. The microbiome samples were collected at 1, 2.5, and 4 y. Caries groups consisted of children who remained caries free (International Caries Detection and Assessment System [ICDAS] = 0) at all time points (CFAT) (n = 50); children diagnosed with caries (ICDAS ≥ 1) at 6.5 y (C6.5), 4 y (C4), or 2.5 y of age (C2.5); and children with early caries or advanced caries lesions at specific time points. Microbial community analyses were performed on zero-radius operational taxonomic units (zOTUs) obtained from V4 of 16S ribosomal RNA gene amplicon sequences. The oral microbiome of the children was affected by various factors, including antibiotic use, demographics, and dietary habits of the children and their caregivers. At all time points, various risk factors explained more of the variation in the dental plaque microbiome than in saliva. At 1 y, composition of saliva of the C4 group differed from that of the CFAT group, while at 2.5 y, this difference was observed only in plaque. At 4 y, multiple salivary and plaque zOTUs of genera Prevotella and Leptotrichia were significantly higher in samples of the C6.5 group than those of the CFAT group. In conclusion, up to 3 y prior to clinical caries detection, the oral microbial communities were already in a state of dysbiosis that was dominated by proteolytic taxa. Plaque discriminated dysbiotic oral ecosystems from healthy ones better than saliva.

Abstract
Neuroendocrine liver metastases (NELM) are very heterogeneous with respect to the clinical presentation and the prognosis. The treatment of NELMs requires a multidisciplinary approach and patients with NELM should be referred to a specialized center. When possible, the resection of NELMs provides the best long-term results. The general selection criteria for liver resection include an acceptable general physical condition for a large liver operation, tumors with a favorable differentiation grade 1 or 2, a lack of extrahepatic lesions, a sufficient residual liver volume and the possibility to resect at least 70% of the metastases. Supplementary treatment, including simultaneous liver ablation, are generally safe and can increase the number of patients who can be considered for surgery. For patients with resectable NELM, the resection of the primary tumor is recommended either in a 2-stage or combined procedure. In selected patients with nonresectable NELM a liver transplantation can be carried out, which can be associated with excellent long-term results.

Abstract
Abstract
Study question
What changes occur in the endometrium during ageing and how they may affect fertility?
Summary answer
The endometrial transcriptome of women of advanced maternal age is significantly different from the young women, indicating specific pathways involved in endometrial ageing.
What is known already
A woman’s peak reproductive years are considered in her twenties. Trending postponed family planning, unfortunately, brings more women in their late forties to fertility specialists to seek for assisted conception. In vitro fertilization (IVF) using donated oocytes is a common approach to overcome the impact of maternal age on ovarian reserve. However, even with the implementation of embryo that underwent pre-implantation genetic testing, the IVF success rate drops significantly in the late forties. It still remains unclear which age-related molecular processes take place in the endometrium and whether it may impact the ability to support embryo implantation.
Study design, size, duration
Endometrial transcriptome profiling was done in 44 women undergoing endometrial receptivity evaluation at hormonal replacement therapy before IVF. Patients younger than 29 were considered as young maternal age group (YMA, age 23-27) and women older than 45 were considered as advanced maternal age group (AMA, age 47-50).
Participants/materials, setting, methods
Endometrial biopsies were obtained on day 5 of progesterone treatment and RNA was extracted. All endometrial samples were evaluated as receptive based on the expression of 57 common endometrial receptivity markers. Study group samples (12 YMA + 12 AMA) were subject to Illumina RNA sequencing. The sequences were annotated using the RefSeq database and differential expression analysis was performed using DeSeq2.We validated our results (10 YMA + 10 AMA) usingquantitative-PCR and histological validation.
Main results and the role of chance
A total of 37228 mRNA transcripts were expressed in the analyzed endometrial samples. After multiple testing corrections, 144 significantly differentially expressed(DE) transcripts (92 up-regulated, 52 down-regulated) were identified in the endometrium of the AMA versus YMAgroup. Overexpressed genes were associated with decidualization (ALDH3A1), endometrial receptivity (EML5, GALNT12), cell cycle (CDKN2A) and signal transduction, while down-regulated genes included sugar metabolism and inflammation (C2CD4B, NFKB), cellular motility (SPAG6)and progesterone signaling (RPL9). The pathways most affected by age were cellular remodeling, cell motility and migration, and immune response. Interestingly, some of the identified DE genes have been previously associated with ageing. Our results suggest the involvement of p16-associated cellular senescence and the suppression of metabolic and inflammatory processes essential for endometrial preparation for embryo transfer.
Limitations, reasons for caution
The study includes only patients undergoing hormonal replacement therapy and it is unclear whether the same processes are affected by age in the natural cycles.
Wider implications of the findings
These findings allow us to explain the age-related molecular changes that take place in the endometrial tissue. Understanding these alterations and using them in assisted reproductive technology may help to improve infertility management in women with advanced reproductive age.

Abstract
Abstract
Study question
Is the microRNA content different in uterine fluid (UF) from women with recurrent implantation failure (RIF) compared to healthy fertile women?
Summary answer
The miRNA content is altered in the UF of women with RIF compared to healthy fertile women.
What is known already
Previous studies indicate that microRNAs secreted from endometrial cells into the UF are involved in endometrial receptivity and embryo implantation. Moreover, endometrial miRNAs are dysregulated in women with RIF and poor endometrial receptivity has been suggested as a putative cause of the condition.
Study design, size, duration
This is a descriptive experimental case-control study where microRNA abundancy in UF was compared between women with RIF (n = 34) and healthy fertile women (n = 17). Study participants were recruited at two university clinics in Stockholm, Sweden, and Tartu, Estonia. UF samples were collected vaginally in the receptive phase on day LH + 7-9 by flushing the uterine cavity with sterile saline. RIF was defined as three failed in vitro fertilization (IVF) cycles with good-quality embryos.
Participants/materials, setting, methods
To identify miRNAs in UF we performed small RNA sequencing. Differential expression analysis (DESeq2) was used to compare the abundancy of miRNAs in UF between the two groups. Dysregulated miRNAs were externally validated using relevant published datasets and further analyzed using tools such as target gene prediction (miRTarBase) and biological KEGG pathway analysis (g:Profiler). Technical validation was performed on two miRNAs with quantitative real-time PCR (RT-PCR).
Main results and the role of chance
In total, we identified 61 differentially abundant UF microRNAs with a false discovery rate of < 0.05 and fold change (FC) of -2 or 2. Out of these, 34 were up-regulated and 27 were down-regulated. External validation based on published literature showed that several of the dysregulated miRNAs are expressed in endometrial epithelial cells and have been described in extracellular vesicles from the endometrium and in the context of endometrial receptivity and RIF. Using publicly available single-cell transcriptome data, we found that the predicted target genes of our microRNAs are expressed both in the trophectoderm of human blastocysts and in epithelial cells of mid-secretory endometrium. Furthermore, the predicted miRNA target genes were significantly enriched in 25 pathways critical for endometrial receptivity and embryo implantation. Technical validation of hsa-miR-486-5p (FC -20.32; p-value=0.004) and hsa-miR-92b-3p (FC -9.72; p-value=0.004) were successfully in line with the sequencing data.
Limitations, reasons for caution
The sample size of this descriptive study was limited. A larger study cohort should be used to validate the differentially abundant microRNAs. Moreover, further in-vitro and in-vivo studies are needed to establish the role of identified miRNAs and their predicted target genes and enriched pathways in the pathogenesis of RIF.
Wider implications of the findings
RIF represents a true challenge in the IVF clinic. We show that total miRNAs can be comprehensively mapped in UF and constitute a promising source of non-invasive biomarkers for RIF that could be further evaluated for its clinical utility. Our findings also give insight into the molecular mechanisms of RIF.

Abstract
STUDY QUESTION Do the spectrum and prevalence of comorbidities of endometriosis and irritable bowel syndrome (IBS) overlap? SUMMARY ANSWER Despite several overlapping symptoms, the most significantly associated comorbidities of endometriosis and IBS are different and are rather related to the organ systems primarily involved in the index diagnosis. WHAT IS KNOWN ALREADY Endometriosis and IBS both have several similar unspecific symptoms, such as recurrent abdominal pain, cramping and anxiety, and both diseases affect young women and are associated with a number of comorbidities causing a poor quality of life. However, a detailed study, revealing the full spectrum of endometriosis and IBS comorbidities in the same study population, is lacking. STUDY DESIGN, SIZE, DURATION This article presents a retrospective in silico analysis of the data from a large nationwide biobank-based cohort consisting of 121 773 women. After excluding all first- and second-degree relatives, the data of up to 65 421 women were analyzed. PARTICIPANTS/MATERIALS, SETTING, METHODS International Classification of Disease-10 diagnosis main codes associated with endometriosis (N80) and IBS (K58) diagnoses were identified from the Estonian Biobank dataset by linking with the Estonian Health Insurance Fund and other relevant registries. The associations between N80 and K58 and other diagnosis codes were tested using logistic regression, adjusting for age at recruitment and 10 genetic principal components to account for potential population stratification. Bonferroni correction was applied to account for multiple testing. MAIN RESULTS AND THE ROLE OF CHANCE Both women with endometriosis and IBS suffered from more conditions compared to the control group, with 226 and 428 diagnosis codes statistically significantly more frequent in women with respective diagnosis compared to controls. Women suffering from both conditions had 275 significantly associated comorbidities. A remarkable proportion of women with IBS or endometriosis suffered also from endometriosis (9.0%) or IBS (13.6%), respectively. In endometriosis, the most prevalent diagnoses were related to diseases of the genitourinary system (33 N-category codes) and in women with IBS, the most associated diagnoses were related to digestive disorders and gastrointestinal tract (52 codes from K-category). Among the most significant diagnoses in endometriosis were uterine leiomyomas (D25), menstrual disorders (N92) and infertility (N97) (P < 1 × 10-315 for all), and in IBS, lactose intolerance (E73), gastritis and duodenitis (K29) and functional dyspepsia (K30) were in the top list of most significant comorbidities (P < 1 × 10-315 for all). LIMITATIONS, REASONS FOR CAUTION The information about the severity stages of endometriosis and subtypes of IBS was not available for analysis. The findings may not be fully extrapolated to all female populations, because all participants were from one geographic area and had good access to health services. WIDER IMPLICATIONS OF THE FINDINGS These findings support previous studies that have found a high prevalence of pre-selected comorbidities in women with endometriosis and IBS. However, taking into account the differences in the full spectrum of comorbidities of endometriosis and IBS may aid in diagnosing these disorders. Women and healthcare providers need to be aware that women with endometriosis are at high risks of complications during pregnancy and should be carefully monitored.

Abstract
Introduction Neuroimaging has been a highly utilized technique for studying traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD) independently of one another, however, neuroimaging has increasingly been identified as a useful tool in better understanding TBI-related psychiatric conditions, such as PTSD. Objectives To complete a systematic review of the literature examining neuroimaging findings in TBI-related PTSD and to highlight the current literature’s limitations in order to strengthen future research. Methods A PRISMA compliant literature search was conducted in PubMed (MEDLINE), PsychINFO, EMBASE, and Scopus databases prior to May of 2019. The initial database query yielded 4388 unique articles, which were narrowed down based on specified inclusion criteria (e.g., clear TBI definition, clinician-diagnosed PTSD, statistically analyzed relationship between neuroimaging and PTSD, quantified time interval between TBI and neuroimaging). Results A final cohort of 10 articles met inclusion criteria, comprising the findings of 482 participants with TBI. Key neuroanatomical findings among the included articles suggest that PTSD is associated with significant changes in whole-brain networks of resting state connectivity and disruptions in bilateral frontal and temporal white matter tracts, fronto-limbic pathways, the internal capsule, and the uncinate fasciculus (Figure 1).
Neuroimaging Findings in TBI-related PTSD. ![]() Replicated Neuroimaging Findings in TBI-related PTSD in the Right Uncinate Fasciculus. ![]() Conclusions Additional inquiry with attention to specified imaging timing post-injury, consistent TBI definitions, clinician-diagnosed TBI and PTSD, and control groups is crucial to extrapolating discrepancies between primary and TBI-related PTSD.

Abstract
Introduction Traumatic brain injury (TBI) may alter dementia progression, although co-occurring neuropsychiatric symptoms (NPS) have received less attention. The mild behavioral impairment (MBI) construct relates NPS to underlying neural circuit disruptions, representing an important area of inquiry regarding TBI and dementia. Objectives (1) to examine the influence of prior TBI history (preceding study enrollment) on MBI incidence in all-cause dementia (prior to dementia diagnosis, i.e. MBI’s original definition) and (2) to utilize MBI domains as a construct for examining the influence of TBI on related NPS across the course of dementia onset and progression. Methods Using National Alzheimer’s Coordinating Center data, individuals progressing from normal cognition to all-cause dementia over 7.6±3.0 years were studied to estimate MBI incidence and symptom domains in 124 participants with prior TBI history compared to 822 without. Results Moderate-severe TBI was associated with the social inappropriateness MBI domain (ORadj.=4.034; p=0.024) prior to dementia onset, and the abnormal perception/thought content domain looking across dementia progression (HRadj.=3.703,
p=0.005). TBI (all severities) was associated with the decreased motivation domain looking throughout dementia progression (HRadj.=1.546,
p=0.014). Conclusions TBI history is associated with particular MBI domains prior to onset and throughout progression of dementia. Understanding TBI’s impact on inter-related NPS may help elucidate underlying neuropathology. Disclosure No significant relationships.

Abstract
Introduction
Sleep disturbances are common following traumatic brain injury (TBI) worsening morbidity and other neuropsychiatric symptoms. Post-TBI alterations in sleep architecture require further study.
Objectives
(1) To evaluate polysomnographic measures of sleep architecture in participants with history of TBI compared to controls and as meta-analyses of pooled means. (2) To evaluate effects of timing and severity of TBI on polysomnographic outcomes.
Methods
PRISMA compliant systematic review was conducted of MEDLINE, PsycINFO, EMBASE and Scopus. Inclusion criteria: 1) reporting polysomnography in the context of TBI and 2) operationalizing TBI using clear/formalized criteria. Data were pooled in random-effects meta-analyses with outcomes expressed as mean differences (MD).
Results
In participants with TBI, sleep was comprised of 19.39% REM sleep, 8.13% N1, 51.18% N2, and 17.53% N3, as determined by meta-analyses of single means. Total sleep time was reduced in chronic (>6 months) TBI compared to acute-intermediate TBI (<6 months) (p=0.01). Compared to controls, participants with TBI differed with increased N1 sleep (MD=0.64%; 95%CI=0.02,1.25; p=0.04), reduced sleep efficiency (MD=-1.65%; 95%CI=-3.18,-0.12; p=0.03), and reduced sleep latency on the multiple sleep latency test (MD=-5.90mins; 95%CI=-10.09,-1.72; p<0.01). On sub-group analyses, participants with mild TBI differed from controls with reduced total sleep time (MD=-29.22mins, 95%CI=-54.16,-4.27; p=0.02). Similarly, participants with acute-intermediate TBI exhibited increased sleep latency compared to controls (MD=8.96mins; 95%CI=4.07,13.85; p<0.01) and differed significantly from participants with chronic TBI (X2(1,N=608)=6.54; p=0.01).
Conclusions
Sleep architecture is altered following TBI with potential implications regarding functional outcomes and recovery. These alterations appear to differ based on severity of injury and time since injury.

Abstract
Abstract
Background
Labor participation among patients with chronic diseases is lagging behind, particularly in the Netherlands. Most workers with a chronic disease might be able to deal with their disease and work participation, but a specific group needs support preferably. This study focuses on the development of a work-related support intervention in clinical care to promote sustainable work participation of patients with chronic diseases who regularly visit the outpatient clinic.
Methods
The first four steps of the Intervention Mapping (IM) approach were used to develop the intervention for a Dutch university hospital. A needs assessment based on a literature review, expert opinions and experiences, a qualitative study with healthcare professionals (n = 9) and consultation with financial staff (Step 1) was used to formulate objectives of the intervention (Step 2). Guided by theory-based methods and practical applications (Step 3), an intervention program, including training and tools for healthcare professionals (medical specialists and nurse specialists), was developed (Step 4).
Results
The needs assessment revealed the importance of stepped care comprising: screening; risk stratification; and if targeted, a problem assessment and providing tailored work-related support, including follow-up. In order to provide work-related support in clinical care, behavioral change of healthcare professionals is necessary. To change their behavior, a program, two training sessions for healthcare professionals and practical tools (screening list, conversation cards and a map with work-related support options) were developed.
Conclusions
To provide work-related support in clinical care for patients with chronic diseases, healthcare professionals need information, skill building training and tools. Despite providing support in care-as-usual, additional time is needed and must be financed. Cost effectiveness evaluation of the intervention is a necessary next step.
Key messages
Healthcare professionals should discuss ‘work’ with targeted patients. To provide work-related support in clinical care, healthcare professionals need knowledge, skills, tools and time.

Abstract
Abstract
Background
Information about the prevalence of current Major Depressive Episode (MDE) across European countries is essential for its monitoring and for the development of evidence- based mental health policies. The aims were to: 1) estimate the prevalence of MDE by country in Europe; and 2) assess variations in prevalence between countries.
Methods
Data from participants of 27 countries that completed the questionnaire of the second wave of the European Health Interview Survey (EHIS-2) were analysed (n = 258,888). The prevalence of MDE was quantified using the Patient Health Questionnaire-8 (PHQ-8) with a cut-off score of ≥ 10. Prevalence and 95% Confidence Intervals (CI) were estimated for each country. Variation in prevalence (country vs the rest) was evaluated using bivariable and multivariable negative binomial regression models considering the specific country as the main explanatory variable. From these models, crude Prevalence Ratios (PR) and adjusted Prevalence Ratios (aPR) were obtained.
Results
The overall prevalence of current MDE in Europe was 6.38% (6.24%-6.52%). The country with the lowest prevalence was the Czech Republic (2.58%, 2.14%-3.02%) and the country with highest prevalence Iceland (10.33%, 9.33%-11.32%). In all the countries (except for Finland and Croatia) prevalence was higher in women than in men. The countries with the highest aPR were Germany (aPR: 1.80, 95% CI: 1.71-1.89) and Luxembourg (aPR: 1.50, 95% CI: 1.35-1.66), while Slovakia (aPR: 0.28, 95% CI: 0.24-0.33) and the Czech Republic (aPR: 0.32, 95% CI: 0.27-0.38) exhibited the lowest aPR.
Conclusions
Considerable variability in the prevalence of MDE by country in Europe was observed without a clear pattern. These results serve as baseline for monitoring the prevalence of MDE at a European level and suggest a need for developing preventive strategies against depression, particularly in those countries identified with the highest prevalence.
Key messages
The results of this study show that the overall prevalence of MDE is high (6.38%), with important variation across countries (ranging from 2.58% in the Czech Republic to 10.33% in Iceland). The results found could serve as a reference for the monitoring of MDE in Europe and for the development of screening and preventive strategies both at European level as well as at a country level.
