RESUMO

BACKGROUND: The prevalence of teenage pregnancy in Colombia is higher than the worldwide average. The identification of socio-geographical disparities might help to prioritize public health interventions. AIM: To describe variation in the probability of teenage maternity across geopolitical departments and socio-geographical intersectional strata in Colombia. METHODS: A cross-sectional study based on live birth certificates in Colombia. Teenage maternity was defined as a woman giving birth aged 19 or younger. Multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) was applied using multilevel Poisson and logistic regression. Two different approaches were used: (1) intersectional: using strata defined by the combination of health insurance, region, area of residency, and ethnicity as the second level (2) geographical: using geopolitical departments as the second level. Null, partial, and full models were obtained. General contextual effect (GCE) based on the variance partition coefficient (VPC) was considered as the measure of disparity. Proportional change in variance (PCV) was used to identify the contribution of each variable to the between-strata variation and to identify whether this variation, if any, was due to additive or interaction effects. Residuals were used to identify strata with potential higher-order interactions. RESULTS: The prevalence of teenage mothers in Colombia was 18.30% (95% CI 18.20-18.40). The highest prevalence was observed in Vichada, 25.65% (95% CI: 23.71-27.78), and in the stratum containing mothers with Subsidized/Unaffiliated healthcare insurance, Mestizo, Rural area in the Caribbean region, 29.08% (95% CI 28.55-29.61). The VPC from the null model was 1.70% and 9.16% using the geographical and socio-geographical intersectional approaches, respectively. The higher PCV for the intersectional model was attributed to health insurance. Positive and negative interactions of effects were observed. CONCLUSION: Disparities were observed between intersectional socio-geographical strata but not between geo-political departments. Our results indicate that if resources for prevention are limited, using an intersectional socio-geographical approach would be more effective than focusing on geopolitical departments especially when focusing resources on those groups which show the highest prevalence. MAIHDA could potentially be applied to many other health outcomes where resource decisions must be made.

RESUMO

Genes encoding B lineage-restricted transcription factors are frequently mutated in B-lymphoid leukemias, suggesting a close link between normal and malignant B-cell development. One of these transcription factors is early B-cell factor 1 (EBF1), a protein of critical importance for lineage specification and survival of B-lymphoid progenitors. Here, we report that impaired EBF1 function in mouse B-cell progenitors results in reduced expression of Myc. Ectopic expression of MYC partially rescued B-cell expansion in the absence of EBF1 both in vivo and in vitro. Using chromosome conformation analysis in combination with ATAC-sequencing, chromatin immunoprecipitation-sequencing, and reporter gene assays, six EBF1-responsive enhancer elements were identified within the Myc locus. CRISPR-Cas9-mediated targeting of EBF1-binding sites identified one element of key importance for Myc expression and pro-B cell expansion. These data provide evidence that Myc is a direct target of EBF1. Furthermore, chromatin immunoprecipitation-sequencing analysis revealed that several regulatory elements in the Myc locus are targets of PAX5. However, ectopic expression of PAX5 in EBF1-deficient cells inhibits the cell cycle and reduces Myc expression, suggesting that EBF1 and PAX5 act in an opposing manner to regulate Myc levels. This hypothesis is further substantiated by the finding that Pax5 inactivation reduces requirements for EBF1 in pro-B-cell expansion. The binding of EBF1 and PAX5 to regulatory elements in the human MYC gene in a B-cell acute lymphoblastic leukemia cell line indicates that the EBF1:PAX5:MYC regulatory loop is conserved and may control both normal and malignant B-cell development.

RESUMO

B lymphocyte development is dependent on the interplay between the chromatin landscape and lineage-specific transcription factors. It has been suggested that B lineage commitment is associated with major changes in the nuclear chromatin environment, proposing a critical role for lineage-specific transcription factors in the formation of the epigenetic landscape. In this report, we have used chromosome conformation capture in combination with assay for transposase-accessible chromatin sequencing analysis to enable highly efficient annotation of both proximal and distal transcriptional control elements to genes activated in B lineage specification in mice. A large majority of these genes were annotated to at least one regulatory element with an accessible chromatin configuration in multipotent progenitors. Furthermore, the majority of binding sites for the key regulators of B lineage specification, EBF1 and PAX5, occurred in already accessible regions. EBF1 did, however, cause a dynamic change in assay for transposase-accessible chromatin accessibility and was critical for an increase in distal promoter-enhancer interactions. Our data unravel an extensive epigenetic priming at regulatory elements annotated to lineage-restricted genes and provide insight into the interplay between the epigenetic landscape and transcription factors in cell specification.

RESUMO

OBJECTIVES: Self-assessment instruments are commonly used in audiological rehabilitation. However, several studies highlight the lack of multidimensionality in existing outcome measures, with the consequence that they only partially capture aspects of functioning in everyday life for people living with hearing loss. This study aimed to develop and investigate the content validity of a self-assessment instrument based on the validated Brief International Classification of Functioning, Disability, and Health Core Set for Hearing Loss. DESIGN: The design was a two-part instrument development study. The first part focused on the item-generation process of the instrument, named the Hearing and Functioning in Everyday Life Questionnaire (HFEQ) during an experts' workshop. The second part focused on international content validation of the instrument using group interviews. Strategic sampling was used and 30 adults with hearing loss from India, South Africa, and the United States participated in the group interviews. RESULTS: The expert's workshop resulted in the first version of the HFEQ containing 30 items. The results from group interviews show that the content of the HFEQ was considered to be valid concerning its relevance, comprehensiveness, and comprehensibility. A majority (73%) of the HFEQ items were perceived by the participants as relevant and easy to comprehend. For the remaining 27% of the items, the content was perceived to be relevant in all countries, but some terms and expressions were reported to require rewording or clearer examples. These modifications will be made in the next step of the development process. CONCLUSION: Content validation of the HFEQ demonstrates promising results, with participants perceiving the content as relevant and comprehensible. Further psychometric validation is required to investigate other psychometric properties, such as construct validity and reliability. The HFEQ has the potential to become a valuable new instrument for assessing everyday functioning in people with hearing loss in audiological rehabilitation and in research.

RESUMO

Maturation of lymphoid cells is controlled by the action of stage and lineage-restricted transcription factors working in concert with the general transcription and chromatin remodeling machinery to regulate gene expression. To better understand this functional interplay, we used Biotin Identification in human embryonic kidney cells to identify proximity interaction partners for GATA3, TCF7 (TCF1), SPI1, HLF, IKZF1, PAX5, ID1, and ID2. The proximity interaction partners shared among the lineage-restricted transcription factors included ARID1a, a BRG1-associated factor complex component. CUT&RUN analysis revealed that ARID1a shared binding with TCF7 and GATA3 at a substantial number of putative regulatory elements in mouse T cell progenitors. In support of an important function for ARID1a in lymphocyte development, deletion of Arid1a in early lymphoid progenitors in mice resulted in a pronounced developmental arrest in early T cell development with a reduction of CD4+CD8+ cells and a 20-fold reduction in thymic cellularity. Exploring gene expression patterns in DN3 cells from Wt and Arid1a-deficient mice suggested that the developmental block resided in the DN3a to DN3b transition, indicating a deficiency in ß-selection. Our work highlights the critical importance of functional interactions between stage and lineage-restricted factors and the basic transcription machinery during lymphocyte differentiation.

RESUMO

BACKGROUND AND AIMS: Elevated circulating levels of CathepsinD (CatD) have been linked to metabolic deviations including liver inflammation. We investigated 1) whether supplementation with probiotics and/or fish oil affects CatD and 2) whether the CatD concentration would associate with gestational diabetes (GDM), low-grade inflammation, lipid metabolism, body fat % and dietary composition. METHODS AND RESULTS: Overweight/obese pregnant women (n = 438) were randomized into fish oil + placebo, probiotics + placebo, fish oil + probiotics or placebo + placebo groups. Fish oil contained 1.9 g docosahexaenoic acid and 0.22 g eicosapentaenoic acid and probiotics were Lacticaseibacillusrhamnosus HN001 (formerly Lactobacillusrhamnosus HN001) and Bifidobacteriumanimalis ssp. lactis 420, 1010 colony-forming units each). Serum CatD levels were analysed by ELISA, GlycA and lipid metabolites by NMR, high sensitive C-reactive protein (hsCRP) by immunoassay, and intakes of energy yielding nutrients and n-3 and n-6 fatty acids from food diaries at both early and late pregnancy. GDM was diagnosed by OGTT. CatD concentrations did not differ between the intervention groups or by GDM status. Multivariable linear models revealed that body fat % and GlycA affected CatD differently in healthy women and those with GDM. CONCLUSION: The serum CatD concentration of pregnant women was not modified by this dietary intervention. Serum CatD was influenced by two parameters, body fat and low grade inflammation, which were dependent on the woman's GDM status. CLINICAL TRIAL REG.

RESUMO

OBJECTIVE: This scoping review investigated key findings about hearing loss (HL) in the working life (WL) from a well-being perspective. DESIGN: A scoping review protocol was used to search the literature and to explore and extract key findings. A narrative analysis of key findings was used to group the data into themes. Study sample: Fifty-three articles from 29 different journals were included in the analysis. RESULTS: The narrative analysis identified three broad themes; individual aspects, work environment and work organisation. Individual aspects concerned problems that workers with HL experienced in their working lives, strategies they used to manage their working lives and different aspects of health in relation to WL. Work environment focussed on the physical, organisational and social work environment. Work organisation identified aspects related to division of labour and employment status. CONCLUSIONS: Several of the included papers revealed lots of findings but did not substantially discuss the findings from a WL perspective. HL and well-being in WL is a multidimensional phenomenon due to the interplay between the individual and the environment. This interplay is rarely discussed in the included papers. Furthermore, intersectional aspects are infrequently highlighted and need to be further explored in future research.

RESUMO

OBJECTIVE: Hearing loss (HL) affects the everyday functioning of millions of people worldwide. The Brief International Classification of Functioning Disability and Health (ICF) core sets for HL was developed to meet the complex health care needs of adults with HL. Because the brief core set for HL has not yet been validated internationally, this study aimed to investigate its validity from an international perspective. DESIGN: A cross-sectional validation study based on data from structured interviews with adults with HL. STUDY SAMPLE: Participants (n = 571) from India, South Africa, Sweden and the US were included. RESULTS: A six-factor solution explained 71% of the variance, focussing on issues related to communication, the social environment, participation in society, health care services, support, relationships and emotions (α = 0.915). Three ICF categories demonstrated low reliability - temperament and personality functions, seeing functions and school education. CONCLUSION: The Brief ICF core set for HL is valid for adults with HL internationally. However, to further increase its international validity, we recommend adding the categories d920 recreation and leisure and replacing d850 school education with the more inclusive block, d810-d839 education.

RESUMO

OBJECTIVE: Complement components, including C4d, can be found on activated platelets, a process associated with vascular disease in SLE. We investigated whether platelet C4d (PC4d) adds additional value to traditional and known lupus-associated risk factors when identifying SLE patients with vascular disease. METHODS: This cross-sectional study included 308 well-characterized SLE patients and 308 matched general population controls. PC4d deposition was analysed using flow cytometry. Values >95% of controls were considered as PC4d positive (+). aPL were determined by Luminex, and the LA test was performed by DRVVT. History of vascular disease (composite and as separate outcomes) was defined at inclusion. RESULTS: SLE patients had increased PC4d deposition as compared with population controls (50 vs 5%, P < 0.0001). PC4d+ positively associated with any vascular events, and separately with venous and cerebrovascular events, and also with all investigated aPL profiles. The association for any vascular event remained statistically significant after adjustment for traditional and SLE-associated risk factors (odds ratio: 2.3, 95% CI: 1.3, 4.3, P = 0.008). Compared with patients negative for both PC4d and LA, patients with double positivity were more likely to have vascular disease (odds ratio: 12.3, 95% CI: 5.4, 29.3; attributable proportion due to interaction 0.8, 95% CI: 0.4, 1.1). CONCLUSION: PC4d+ is associated with vascular events in SLE, independently of traditional and SLE-associated risk factors. Concurrent presence of PC4d and LA seem to interact to further increase the odds for vascular events. Prospective studies should examine whether the aPL/PC4d combination can improve prediction of vascular events in SLE and/or APS.

RESUMO

Natural IgM autoantibodies have been proposed to convey protection from autoimmune pathogenesis. Herein, we investigated the IgM responses in 396 systemic lupus erythematosus (SLE) patients, divided into subgroups based on distinct autoantibody profiles. Depressed IgM levels were more common in SLE than in matched population controls. Strikingly, an autoreactivity profile defined by IgG anti-Ro/La was associated with reduced levels of specific natural IgM targeting phosphorylcholine (PC) antigens and malondialdehyde (MDA) modified-protein, as well as total IgM, while no differences were detected in SLE patients with an autoreactivity profile defined by anti-cardiolipin/ß2glycoprotein-I. We also observed an association of reduced IgM levels with the HLA-DRB1*03 allelic variant among SLE patients and controls. Associations of low IgM anti-PC with cardiovascular disease were primarily found in patients without antiphospholipid antibodies. These studies further highlight the clinical relevance of depressed IgM. Our results suggest that low IgM levels in SLE patients reflect immunological and genetic differences between SLE subgroups.

RESUMO

Increased production of autoantibodies is a characteristic feature of systemic lupus erythematosus (SLE) and there is evidence that several of these autoantibodies may contribute to increased cardiovascular disease (CVD) in SLE. Autoantibodies against the apolipoprotein (apo) B-100 peptides p45 and p210 have been associated with a lower CVD risk in non-SLE cohorts. The aim of the present study was to investigate how SLE affects the occurrence of these potentially protective autoantibodies. The study cohort consisted of 434 SLE patients and 322 age- and sex-matched population controls. Antibodies against native and malondialdehyde (MDA)-modified p45 and p210 were measured by enzyme-linked immunosorbent assay (ELISA). SLE patients had significantly lower levels of p210 immunoglobulin (Ig)G and p45 IgM (both the native and malondialdehyde (MDA)-modified forms). SLE patients with manifest CVD (myocardial infarction, ischaemic cerebrovascular disease or peripheral vascular disease) had lower levels p210 IgG and p45 IgM than SLE patients without CVD. Decreased levels of these autoantibodies were also observed in SLE patients with permanent organ damage, as assessed by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (ACR) Damage Index (SDI). The present findings show that patients with SLE, a condition generally characterized by abundance of autoantibodies of multiple specificities, have reduced levels of antibodies against the apo B-100 antigens p45 and p210 and that the levels of these antibodies are reduced further in SLE patients with CVD. These observations suggest the possibility that an impaired antibody-mediated removal of damaged LDL particles may contribute to the development of vascular complications and organ damage in SLE.

RESUMO

OBJECTIVE: Smoking can induce autoantibodies in persons who are genetically predisposed to rheumatoid arthritis. We investigated the association between smoking and antiphospholipid antibodies (aPL) in systemic lupus erythematosus (SLE), a question not previously addressed. Further, we explored the relationship between smoking, aPL and vascular events (arterial and venous, VE). METHODS: In this cross-sectional study, clinical evaluation and questionnaire data were collected from 367 prevalent SLE patients. At the same time, we measured aPL (anticardiolipin (aCL), anti-ß2 glycoprotein-1 (aß2GP1) antibodies IgG/IgM/IgA, and lupus anticoagulant (LA)), and a large set of other SLE-associated autoantibodies for comparison. Association analyses using logistic regression models with smoking, (ever, former and current with never as reference) and antibody status as outcome variable were performed. As a secondary outcome, we investigated the associations between aPL, smoking and VE. RESULTS: In multivariable-adjusted models ever, and in particular former, cigarette smoking was associated with the most pathogenic aPL; LA, aCL IgG and aß2GP1 IgG. Other SLE-associated autoantibodies were not associated with smoking. The combination of smoking and aPL was strongly associated with VE. We noted a positive interaction between smoking-LA and smoking-'triple aPL' positivity for previous VE. CONCLUSIONS: We investigated a large set of commonly occurring autoantibodies in SLE, but only aPL were positively associated with a history of smoking. This association was especially apparent in former smokers. Among ever regular smokers who were aPL positive, we observed a strikingly high frequency of former VE. The underlying mechanisms and temporality between smoking, aPL and VE need further investigations.

RESUMO

BACKGROUND: Persons with hearing loss (HL) are a vulnerable group in working life. Studies have shown that they are more likely than the general population to be in part-time work, to be unemployed, receive disability pension, and to be on sick leave. Many workers with HL also experience unhealthy work conditions, such as jobs where they experience high demands combined with low control as well as safety concerns and social isolation. There is a lack of studies that focus on factors that promote a healthy, sustainable work situation for the target group. OBJECTIVE: To investigate health factors that contribute to a sustainable work situation for employees with HL. METHODS: The current study was a comparative, observational study with a cross-sectional design including a clinical population of adults with HL. Comparisons were made between workers with HL "in work" and workers with HL on "HL-related sick leave". RESULTS: Seven health factors were identified. Those "in work" experienced a healthier work environment as well as lower levels of mental strain, hearing-related work characteristics and content, cognitively demanding work content, hearing-related symptoms, energy-demanding activities, and bodily aches and pain than those on "HL-related sick leave". CONCLUSION: The results demonstrate a clear pattern regarding health factors for a sustainable working life. The type of job was not related to whether an individual was on sick leave or working. Rather, the work climate and the content of the work mattered.

RESUMO

PURPOSE: The aim of the current study was to explore the construct validity and internal consistency reliability of the International Classification of Functioning, Disability and Health (ICF)-based original English version of the Hearing and Functioning in Everyday Life Questionnaire (HFEQ) and to revise the HFEQ based on the results. METHOD: This study used a cross-sectional survey design. The data were collected using an online survey. Adults with self-reported hearing disability (n = 513) from the United States were included. The ICF components of body functions, activity and participation, and environmental factors were tested as the underlying structure of the HFEQ using confirmatory factor analysis and then adjusted by triangulation with previous content validation. RESULTS: The results of the current study confirmed the ICF components of body functions, activity and participation, and environmental factors as underlying constructs of the HFEQ. However, after triangulation with previous content validation, fine adjustments were made. The revised version of the HFEQ includes two removed items and a fine-tuned factor structure. CONCLUSION: The results confirm that the structure of the HFEQ aligns with the ICF, and the overall results indicate that HFEQ has acceptable construct validity and internal consistency.

RESUMO

BACKGROUND AND OBJECTIVES: Vascular disease is common in systemic lupus erythematosus (SLE) and patients with antiphospholipid antibodies (aPL) are at high risk to develop arterial and venous thrombosis. Since HLA class II genotypes have been linked to the presence of pro-thrombotic aPL, we investigated the relationship between HLA-DRB1 alleles, aPL and vascular events in SLE patients. METHODS: 665 SLE patients of Caucasian origin and 1403 controls were included. Previous manifestations of ischaemic heart disease, ischaemic cerebrovascular disease (ICVD) and venous thromboembolism (together referred to as any vascular events (AVE)) were tabulated. aPL were measured with ELISA. Two-digit HLA-DRB1 typing was performed by sequence-specific primer-PCR. RESULTS: HLA-DRB1*04 was more frequent among SLE patients with ICVD compared to unaffected patients. This association remained after adjustment for known traditional cardiovascular risk factors. HLA-DRB1*13 was associated with AVE. All measured specificities of aPL-cardiolipin IgG and IgM, ß2-glycoprotein-1 IgG, prothrombin (PT) IgG and a positive lupus anticoagulant test were associated with HLA-DRB1*04-while HLA-DRB1*13 was associated with IgG antibodies (ß2-glycoprotein-1, cardiolipin and PT). In patients with the combined risk alleles, HLA-DRB1*04/*13, there was a significant additive interaction for the outcomes AVE and ICVD. CONCLUSIONS: The HLA-DRB1*04 and HLA-DRB1*13 alleles are associated with vascular events and an aPL positive immune-phenotype in SLE. Results demonstrate that a subset of SLE patients is genetically disposed to vascular vulnerability.

RESUMO

OBJECTIVES: To evaluate the agreement and performance of two tests for aPLs with regard to association with manifestations of the APS in patients with SLE. METHODS: We investigated 712 SLE patients and 280 population controls. Cardiolipin and ß(2) glycoprotein-I antibodies were measured with routine ELISA and a new automated method. Three positivity cut-offs (99%, 90% of controls and recommended cut-off by manufacturers) were used. Associations with previous thrombotic events, thrombocytopenia and, in a subgroup of patients, obstetric morbidity (n = 296) were evaluated. Results were compared with the LA test, performed in 380 patients. RESULTS: Inter-test agreement was moderate (demonstrated by κ-values 0.16-0.71). Performance of the two tests was similar: at the 99th percentile cut-off, sensitivity for any thrombotic event ranged from 3.7% to 24.8%, while specificity was 84.7-97.7%. Regardless of assay, IgG isotypes were associated with venous thrombosis and ischaemic cerebrovascular disease, whereas aPLs of IgM isotype were weakly associated with ischaemic heart disease. Associations were greatly affected by aPL level. LA performed better than the specific aPL tests. LA was associated with any thrombotic event, odds ratio 5.4 (95% CI 3.1, 9.4), while the specific aPL tests ranged from non-significant to an odds ratio of 1.9 (95% CI 1.03, 3.4) using criteria cut-off. LA was also convincingly associated with other APS manifestations. CONCLUSION: In relation to thrombotic manifestations, there was moderate agreement but no clear advantages when comparing a routine aPL ELISA with an automated method. APL isotype and titre as well as LA positivity are important for risk assessment in SLE patients.

RESUMO

PURPOSE: Gender differences have been found in the outcomes of vocational rehabilitation (VR) and in Supported Employment (SE), therefore, the purpose of this study was to explore employment specialists' (ES) social representations of gender in relation to work and VR and how these social representations influence the ES's work in the VR process according to SE. METHODS: The qualitative method of focus group discussions was employed. Ten focus groups were held with 39 ESs from four categories of SE organizations in Sweden. Topic analysis was applied to the transcribed material from the focus groups. RESULTS: Five themes with different social representations about gender and disability in relation to VR and working life formed in the analysis: (1) differences in personal and health factors among VR-participants, (2) gender norms in society influencing VR, (3) energy-intensive environmental issues influencing VR, (4) gender-specific interactions in VR, and (5) gendered paths in the welfare system. CONCLUSION: Social representations of higher strains on women with disabilities compared to men with disabilities both in private and working life, which reflect the lived experiences of the ESs, is a possible explanation for gender differences in VR and working life for persons with disabilities.IMPLICATIONS FOR REHABILITATIONGender differences in the outcomes of vocational rehabilitation (VR) interventions have been noticed worldwide. In this study, pervasive social representations about gender and disability in relation to VR were found, but also unconsciousness about gender among VR professionals. Therefore, awareness of gender is necessary in VR.Individualized and person-centered approaches to VR like Supported Employment, although considered best practice, might hide structures like gender, which could lead to reproducing discriminating processes and therefore not achieving gender equality in VR. Therefore, knowledge of discrimination is important in VR.Gender-sensitivity in vocational rehabilitation models with a person-centered and individualized approach is needed and there might also be a need to systematically tailor vocational rehabilitation models to reach gender equality in the outcomes of the interventions. Therefore, gender equality indicators are needed for VR models, to evaluate model effectiveness from a gender perspective.

RESUMO

BACKGROUND: Supported Employment (SE) has shown better results in the employment rate for persons with disabilities than other methods within vocational rehabilitation, but how SE affects the employment rate for subgroups in the interventions needs further attention. OBJECTIVE: To examine previous research regarding the influence of intersecting statuses on the employment rate in SE for people with psychiatric, neuropsychiatric, or intellectual disabilities according to type of diagnosis, sex, race/ethnicity, age, level of education and previous work history. METHODS: A systematic literature search was conducted in nine databases including peer-reviewed articles from 2000 to April 2021. Articles presenting the employment rate in SE interventions according to the intersecting statuses listed in the objective were included. RESULTS: The searches identified 3777 unique records, of which 53 articles were included in data extraction. In most of the included articles, intersecting statuses did not affect the employment rate for people in the SE interventions with psychiatric disabilities. Few studies have examined neuropsychiatric and intellectual disabilities. A majority of the studies subjected to full-text analysis were excluded due to a lack of reporting of the effects of intersecting statuses on the employment rate. The studies that reported on the effects of intersecting statuses on the employment rate often had small samples and lacked statistical power. CONCLUSIONS: Intersecting statuses do not appear to affect the employment rate for people receiving SE interventions, but systematic reviews with pooled samples need to be undertaken because of the low reporting rate and underpowered sample sizes in existing studies.

RESUMO

Objective: To investigate and summarize the literature on the validation of International Classification of Functioning, Disability and Health (ICF) core sets from 2001 to 2019 and explore what research methods have been used when validating ICF core sets.Methods: The current study is a scoping review using a structured literature search.Results: In total, 66 scientific articles were included, of which 23 ICF core sets were validated. Most validation studies were conducted in Europe using a quantitative methodology and were validated from the perspective of patients. Analysis methods differed considerably between the studies, and most ICF core sets were validated only once for a single target population or from a single perspective. The comprehensive core sets were validated more often than the brief core sets, and core sets for stroke and low back pain were validated most often.Conclusion: The results of the current study show that only 66% of the existing ICF core sets are validated. Many of the validation studies are conducted in a European context and from a single perspective. More validation studies of ICF core sets from the perspective of both patients and professionals are needed.Implications for rehabilitationICF core sets aim to facilitate assessments in clinical settings and research.Validation studies indicate in general that the ICF core sets are valid and relevant for patients and professionals in the specific areas explored and thus can be used in rehabilitation settings.To improve the quality of ICF core sets, more validation studies are needed for ICF core sets not yet tested and for ICF core sets that have been validated only in one study or for one specific population or target group.
