Abstract
Background Trans* people's life satisfaction is correlated with established legal frameworks for gender recognition and access to trans*-specific health care (Transgender Europe [TGEU], 2021). TGEU's guidelines to human rights-based principles of trans*-specific health care highlight bodily integrity/autonomy, free self-determination of gender, quality, specialized and decentralized care, and the right to determine reproductive paths as important pillars of gender affirming health care. We conducted a policy comparison across Europe regarding access to gender-affirming health care to assess how adherence to human rights-based principles could be strengthened. Methods We compared access to health care across four main domains: legal framework (e.g., legally recognised genders), insurance coverage (e.g., out of pocket costs), access barriers (e.g., legal requirements to access gender-affirming surgery), and health care offers (e.g., hormone replacement therapy). Criteria were developed in guided brainstorming sessions. Three researchers rated 28 countries across 28 items based on available policy documents. Results The majority of European countries prescribes a medicalised gender-affirming process rather than a self-decided process. Psychiatric diagnosis is also required in most countries to access gender-affirming health care. Gender-affirming health care is partly financed by statutory health insurance in most of the countries. Not all countries authorise full gender-affirming health care. Especially where statutory health insurance-covered gender-affirming health care relied centralised on single outpatient clinics or hospitals, waiting times between 6-24 months are found. Conclusions Many European countries fail to fully comply with TGEU's guidelines to human rights-based principles of trans* health care. Given the negative impact of access barriers on life satisfaction, European countries should target these shortfalls in ensuring gender-affirming health care. Key messages • Non- or only partly covered trans* health care contributes to health inequality. • Regarding trans* people, European countries need to strengthen human-rights based access to gender-affirming health care.

Abstract
Three-dimensional (3D) culture systems have been developed that can re-capitulate organ level responses, simulate compound diffusion through complex structures, and assess cellular heterogeneity of tissues, making them attractive models for advanced in vitro research and discovery. Organoids are a unique subtype of 3D cell culture that are grown from stem cells, are self-organizing, and closely replicate in vivo pathophysiology. Organoids have been used to understand tissue development, model diseases, test drug sensitivity and toxicity, and advance regenerative medicine. However, traditional organoid culture methods are inadequate because they are low throughput and ill-suited for single organoid imaging, phenotypic assessment, and isolation from heterogenous organoid populations. To address these bottlenecks, we have adapted our tissue culture consumable and instrumentation to enable automated imaging, identification, and isolation of individual organoids. Organoids grown on the 3D CytoSortⓇ Array can be reliably tracked, imaged, and phenotypically analyzed using brightfield and fluorescent microscopy as they grow over time, then released and transferred fully intact for use in downstream applications. Using mouse hepatic and pancreatic organoids, we have demonstrated the use of this technology for single-organoid imaging, clonal organoid generation, parent organoid subcloning, and single-organoid RNA extraction for downstream gene expression or transcriptomic analysis. The results validate the ability of the CellRaft AIRⓇ System to facilitate efficient, user-friendly, and automated workflows broadly applicable to organoid research by overcoming several pain points: 1) single organoid time-course imaging and phenotypic assessment, 2) establishment of single cell-derived organoids, and 3) isolation and retrieval of single organoids for downstream applications.

Abstract
There is increasing interest in using modern 'omics technologies, such as whole transcriptome sequencing, to inform decisions about human health safety and chemical toxicity hazard. High throughput methodologies using in vitro assays offer a path forward in reducing or eliminating animal testing. However, many aspects of these technologies need assessment before they will gain the trust of regulators and the public as viable alternative test methods for human health and safety. We used a high throughput whole transcriptome sequence assay (TempO-Seq) to assess the use of three widely used cancer cell lines (HepG2, MCF7, and Ishikawa cells) as in vitro systems for determination of cellular modes of action for two well studied compounds with canonical liver responses: ketoconazole and phenobarbital. We evaluated transcriptomic data to infer points of departure for use in risk analyses of compounds. Both compounds displayed shortcomings in evidence for canonical liver-related responses in any cell line, despite a strong dose response in all three. This raises questions about the competence of simple, mono-cultured cancer cell lines as appropriate surrogates for some adverse effects or toxic endpoints. Points of departure derived from benchmark doses were highly consistent across all three cell lines however, indicating the use of transcriptomic BMD analyses for such purposes would be a reliable and consistent approach.

Abstract
Live-cell imaging is a common data acquisition technique used by biologists to analyze cell behavior. Since manually tracking cells in a video sequence is extremely time-consuming, many automatic algorithms have been developed in the last twenty years to accomplish the task. However, none of these algorithms can yet claim robust tracking performance at the varying of acquisition conditions (e.g., cell type, acquisition device, cell treatments). While many visualization tools exist to help with cell behavior analysis, there are no tools to help with the algorithm's validation. This paper proposes CellTrackVis, a new visualization tool for evaluating cell tracking algorithms. CellTrackVis allows comparing automatically generated cell tracks with ground truth data to help biologists select the best-suited algorithm for their experimented pipeline. Moreover, CellTackVis can be used as a debugging tool while developing a new cell tracking algorithm to investigate where, when, and why each tracking error occurred.

Abstract
Lassa virus (LASV), a Risk Group-4 zoonotic haemorrhagic fever virus, affects sub-Saharan African countries. Lassa fever, caused by LASV, results in thousands of annual deaths. Although decades have elapsed since the identification of the Natal multimammate mouse (Mastomys natalensis) as a natural reservoir of LASV, little effort has been made to characterize LASV infection in its reservoir. The natural route of infection and transmission of LASV within M. natalensis remains unknown, and the clinical impact of LASV in M. natalensis is mostly undescribed. Herein, using an outbred colony of M. natalensis, we investigate the replication and dissemination dynamics of LASV in this reservoir following various inoculation routes. Inoculation with LASV, regardless of route, resulted in a systemic infection and accumulation of abundant LASV-RNA in many tissues. LASV infection in the Natal multimammate mice was subclinical, however, clinical chemistry values were transiently altered and immune infiltrates were observed histologically in lungs, spleens and livers, indicating a minor disease with coordinated immune responses are elicited, controlling infection. Intranasal infection resulted in unique virus tissue dissemination dynamics and heightened LASV shedding, compared to subcutaneous inoculation. Our study provides important insights into LASV infection in its natural reservoir using a contemporary infection system, demonstrating that specific inoculation routes result in disparate dissemination outcomes, suggesting intranasal inoculation is important in the maintenance of LASV in the natural reservoir, and emphasizes that selection of the appropriate inoculation route is necessary to examine aspects of viral replication, transmission and responses to zoonotic viruses in their natural reservoirs.

Abstract
Abstract
Background
Various groups face difficulties in access to, and usage of health care. Research on marginalization in health care, and programs aiming to reduce inequalities usually focus on one single group at a time. Regarding the heterogeneity of groups defined by a few social characteristics, our aim was to question the specificity of barriers, and similarities between different groups.
Methods
The results of a mixed methods study focusing on elderly people with Turkish migration background were compared to the interim results of a qualitative study focusing on transgender persons, and the interim results of a qualitative study focusing persons with trauma related psychiatric diagnoses.
Results
1) While relevant barriers in access to, and usage of health care seem to be group-specific at the first view, their underlying mechanisms of emergence are analogous. 2) Beside more obvious similarities, 3) further barriers arise by the combination of more than the mainly addressed characteristics of the different groups.
Conclusions
Barriers analogous or similar among different groups lead to underlying structural or professionality-related issues. If different dimensions of marginalization intersect, they may be disguised by a concentration on single characteristics. To target health inequalities on the long term, a closer look on similarities between groups facing health inequalities could improve the development of programs for a broader range of persons.
Key messages
The comparison of different marginalized groups is useful to identify and target systematic inequalities in health care. Researchers and stakeholders should consider mechanisms of multiple marginalization.

Abstract
Abstract
A method for the simultaneous determination of methyldibromo glutaronitrile, bronopol, and broni-dox in cosmetics, based on liquid chromatography with electrochemical detection, is described. The method is suitable for both aqueous products and emulsions. The detection limit is better than 0.002% for all analytes. Recoveries from an emulsion, spiked to concentrations of 0.03% of the analytes, were 100.4% for bronopol [relative standard deviation (RSD), 0.43%], 97.1% for bronidox (RSD, 0.83%), and 98.4% for methyldibromo glutaronitrile (RSD, 1.7%). Repeatabilities were calculated from 10 replicate analyses of commercial samples. The repeatability for bronopol from an emulsion containing 0.047% bronopol was 0.0027% (RSD, 1.99%); for bronidox from a lotion containing 0.027% bronidox, 0.0014% (RSD, 1.86%); and for methyldibromo glutaronitrile from an emulsion containing 0.031% methyldibromo glutaronitrile, 0.0019% (RSD, 2.16%). A ruggedness test showed that sample amount influenced the results for all 3 analytes. The results obtained for bronidox also depended on detection parameters and composition of extraction solvent. The method was applied to 138 cosmetic products and performed trouble free during these analyses. Bronopol was found in 14 samples, and bronidox was found in 4 samples, including a baby hair lotion, in which it is prohibited. Methyldibromo glutaronitrile was present in 27 samples, including creams, lotions, and sun protection cosmetics.

Abstract
Abstract
A collaborative study was conducted for the determination of paralytic shellfish poisoning (PSP) toxins in shellfish. The method used liquid chromatography with fluorescence detection after prechromatographic oxidation of the toxins with hydrogen peroxide and periodate. The PSP toxins studied were saxitoxin (STX), neosaxitoxin (NEO), gonyautoxins 2 and 3 (GTX2,3; together), gonyautoxins 1 and 4 (GTX1,4; together), decarbamoyl saxitoxin (dcSTX), B-1 (GTX5), C-1 and C-2 (C1,2; together), and C-3 and C-4 (C3,4; together). B-2 (GTX6) toxin was also included, but for qualitative identification only. Mussels, both blank and naturally contaminated, were mixed and homogenized to provide a variety of PSP toxin mixtures and concentration levels. The same procedure was followed with clams, oysters, and scallops. Twenty-one test samples in total were sent to 21 collaborators who agreed to participate in the study. Results were obtained from 18 laboratories representing 14 different countries. It is recommended that the method be adopted First Action by AOAC INTERNATIONAL.

Abstract
Abstract
Background
Many elderly people of Turkish origin choose a transnational lifestyle and commute between Germany and Turkey every few months. These circular migrants often suffer from chronic diseases. The transnational lifestyle can lead to discontinuities in long-term medication and irregular check-ups. If continuity of care is not ensured transnationally, health risks arise.
Methods
In a mixed-methods study 8 expert-interviews with general practitioners and 25 guideline interviews were conducted with circular migrants to analyze their medication adherence. Additional quantitative analyses were conducted based on data from a German statutory health insurance popular with migrants to investigate discontinuities of prescribed medication.
Results
Cross-border care involves different health risks with regard to medication adherence. For example, patients in Germany rarely receive the amount of medication they need for their stay in Turkey and there are discontinuities in medication delivery. The multi-perspective insight into the patients’ experiences of medical care and the view of general practitioners shows strong variations of preferred strategies to handle the challenges of transnational medication management. Single strategies, such as leaving the health insurance card in one state for prescription and sending of medication through family members or asking for higher amounts of medication to store before travel, lead to frustration both at GPs’ and patients’ sides. GPs experience high pressure by the health system’s structure in providing good care for the patients, especially in providing enough time for information transfer between GPs and patients.
Conclusions
Transnational solutions for health care, and in particular medication care, such as an interprofessional collaborative care across borders or transnational e-health records need to be developed.
Key messages
A transnational lifestyle can lead to discontinuities in the provision of medication. Transnational, inter-professional cooperation is needed to ensure continuity of health care for circular migrants.

Abstract
Abstract
Background
General practitioners (GPs) have a gatekeeping function in the healthcare system. Research shows that patients of Turkish origin in Germany manage to access specialist care less often than non-immigrant patients. Underlying could be problems related to interactions with the GP. Focusing on interaction instead of individual patients’ characteristics might help identifying underappreciated barriers in health care.
Methods
We conducted a scoping review to identify research on interaction-related aspects of GP consultations of people of Turkish origin. Goffman’s interactional theory was used for operationalisation. Analysis focused on the process of consultation from the perspectives of patients, GPs, and interpreters. Additionally, noticeable issues in researchers’ perspectives on migrants’ utilization of health care were identified.
Results
Patients of Turkish origin expect similar professional performances from their GPs as patients without a migration background. If informal interpreters take part, misinformation might remain unrecognised. Frequently, GPs experience insecurity, which sometimes results in lower empathy and prejudice-based, unprofessional reactions or misdiagnoses. Researchers’ interpretations refer partly to unfounded explanations such as a homogeneous Turkish culture or somatization tendencies of Turkish patients.
Conclusions
Difficulties in GP care of patients of Turkish origin, and access barriers to specialist care, arise less from culture-bound performances of these patients as from culturalising expectations and performances of GPs. Researchers often show similar expectations and interpretations. Such culturalising interpretations should be avoided in future research.

Abstract
Titin (TTN) has multifunctional roles in sarcomere assembly, mechanosignaling transduction, and muscle stiffness. TTN splicing generates variable protein sizes with different functions. Therefore, understanding TTN splicing is important to develop a novel treatment for TTN-based diseases. The I-band TTN splicing regulated by RNA binding motif 20 (RBM20) has been extensively studied. However, the Z- and M-band splicing and regulation remain poorly understood. Herein, we aimed to define the Z- and M-band splicing in striated muscles and determined whether RBM20 regulates the Z- and M-band splicing. We discovered four new Z-band TTN splicing variants, and one of them dominates in mouse, rat, sheep, and human hearts. But only one form can be detected in frog and chicken hearts. In skeletal muscles, three new Z repeats (Zr) were detected, and Zr4 to 6 exclusion dominates in the fast muscles, whereas Zr4 skipping dominates in the slow muscle. No developmental changes were detected in the Z-band. In the M-band, two new variants were discovered with alternative 3' splice site in exon363 (Mex5) and alternative 5' splice site in intron 362. However, only the sheep heart expresses two new variants rather than other species. Skeletal muscles express three M-band variants with altered ratios of Mex5 inclusion to Mex5 exclusion. Finally, we revealed that RBM20 does not regulate the Z- and M-band splicing in the heart, but does in skeletal muscles. Taken together, we characterized the Z- and M-band splicing and provided the first evidence of the role of RBM20 in the Z- and M-band TTN splicing.

Abstract
Titin (TTN) is a major disease-causing gene in cardiac muscle. Titin (TTN) contains 363 exons in human encoding various sizes of TTN protein due to alternative splicing regulated mainly by RNA binding motif 20 (RBM20). Three isoforms of TTN protein are produced by mutually exclusive exons 45 (Novex 1), 46 (Novex 2), and 48 (Novex 3). Alternatively splicing in Novex isoforms across species and whether Novex isoforms are associated with heart disease remains completely unknown. Cross-species exon comparison with the mVISTA online tool revealed that exon 45 is more highly conserved across all species than exons 46 and 48. Importantly, a conserved region between exons 47 and 48 across species was revealed for the first time. Reverse transcript polymerase chain reaction (RT-PCR) and DNA sequencing confirmed a new exon named as 48′ in Novex 3. In addition, with primer pairs for Novex 1, a new truncated form preserving introns 44 and 45 was discovered. We discovered that Novex 2 is not expressed in the pig, mouse, and rat with Novex 2 primer pairs. Unexpectedly, three truncated forms were identified. One TTN variant with intron 46 retention is mainly expressed in the human and frog heart, another variant with co-expression of exons 45 and 46 exists predominantly in chicken and frog heart, and a third with retention of introns 45 and 46 is mainly expressed in pig, mouse, rat, and chicken. Using Rbm20 knockout rat heart, we revealed that RBM20 is not a splicing regulator of Novex variants. Furthermore, the expression levels of Novex variants in human hearts with cardiomyopathies suggested that Novexes 2 and 3 could be associated with dilated cardiomyopathy (DCM) and/or arrhythmogenic right ventricular cardiomyopathy (ARVC). Taken together, our study reveals that splicing diversity of Novex exons across species and Novex variants might play a role in cardiomyopathy.

Abstract
SmB6 is a strongly correlated mixed-valence Kondo insulator with a newly discovered surface state, proposed to be of non-trivial topological origin. However, the surface state dominates electrical conduction only below T∗ ≈ 4 K (ref. ), limiting its scientific investigation and device application. Here, we report the enhancement of T∗ in SmB6 under the application of tensile strain. With 0.7% tensile strain we report surface-dominated conduction at up to a temperature of 240 K, persisting even after the strain has been removed. This can be explained in the framework of strain-tuned temporal and spatial fluctuations of f-electron configurations, which might be generally applied to other mixed-valence materials. We note that this amount of strain can be induced in epitaxial SmB6 films via substrate in potential device applications.

Abstract
BACKGROUND Certain glomerulopathies are associated with increased levels of CD80 (B7-1). We measured the urinary excretion of CD80, podocyturia and proteinuria in controls and in subjects with Fabry disease either untreated or on enzyme replacement therapy (ERT). METHODS Cross-sectional study including 65 individuals: controls (n = 20) and Fabry patients (n = 45, 23 of them not on ERT and 22 on ERT). Variables included age, gender, urinary protein/creatinine ratio (UPCR), estimated glomerular filtration rate (eGFR), urinary uCD80/creatinine ratio (uCD80) and podocyturia. CD80 mRNA expression in response to lyso-Gb3, a bioactive glycolipid accumulated in Fabry disease, was studied in cultured human podocytes. RESULTS Controls and Fabry patients did not differ in age, eGFR and gender. However, UPCR, uCD80 and podocyturia were significantly higher in Fabry patients than in controls. As expected, Fabry patients not on ERT were younger and a higher percentage were females. Non-ERT Fabry patients had less advanced kidney disease than ERT Fabry patients: UPCR was lower and eGFR higher, but uCD80 and podocyturia did not differ between non-ERT or ERT Fabry patients. There was a significant correlation between uCD80 and UPCR in the whole population (r 0.44, p 0.0005) and in Fabry patients (r 0.42, p 0.0046). Lyso-Gb3 at concentrations found in the circulation of Fabry patients increased uCD80 expression in cultured podocytes. CONCLUSIONS Fabry disease is characterized by early occurrence of increased uCD80 excretion that appears to be a consequence of glycolipid accumulation. The potential for uCD80 excretion to reflect early, subclinical renal Fabry involvement should be further studied.

Abstract
OBJECTIVE Colocation of mental health screening, assessment, and treatment in primary care reduces stigma, improves access, and increases coordination of care between mental health and primary care providers. However, little information exists regarding older adults' attitudes about screening for mental health problems in primary care. The objective of this study was to evaluate older primary care patients' acceptance of and satisfaction with screening for depression and anxiety. METHODS The study was conducted at an urban, academically affiliated primary care practice serving older adults. Study patients (N = 107) were screened for depression/anxiety and underwent a post-screening survey/interview to assess their reactions to the screening experience. RESULTS Most patients (88.6%) found the length of the screening to be "just right." A majority found the screening questions somewhat or very acceptable (73.4%) and not at all difficult (81.9%). Most participants did not find the questions stressful (84.9%) or intrusive (91.5%); and a majority were not at all embarrassed (93.4%), upset (93.4%), or uncomfortable (88.8%) during the screening process. When asked about frequency of screening, most patients (72.4%) desired screening for depression/anxiety yearly or more. Of the 79 patients who had spoken with their physicians about mental health during the visit, 89.8% reported that it was easy or very easy to talk with their physicians about depression/anxiety. Multivariate results showed that patients with higher anxiety had a lower positive reaction to the screen when controlling for gender, age, and patient-physician communication. CONCLUSIONS These results demonstrate strong patient support for depression and anxiety screening in primary care.

Abstract
Goodpasture's syndrome is a rare disease that involves rapidly progressive kidney failure as well as hemorrhagic lung disease. It is a form of autoimmune disorder with unusual features; marked male preponderance, in contrast with other autoimmune disease in which females are at far greater risk. The autoantibodies are directed again the carboxy-extension non-collagenous (NC1) portion of one of the basement membrane-specific collagen IV alpha 3 chains. Basal laminas throughout the body share this structure, including those in kidney, lung and skin. But curiously, skin is rarely involved in Goodpasture's syndrome. Hyaluronan is a large extracellular matrix carbohydrate polymer. Half of total body hyaluronan occurs in skin. High molecular weight hyaluronan, a potent immunosuppressive polymer, might be functioning as an immune shield for skin in Goodpasture's syndrome, and be the basis for the anomaly. A summary of this putative effect is described, including possible molecular mechanisms involved, and suggestions for testing this hypothesis.
