RESUMO

RESUMEN Introducción: El Índice de Severidad del Embolismo Pulmonar (PESI) se utiliza para categorizar el riesgo de mortalidad en el tromboembolismo pulmonar agudo (TEP). Por definición, los pacientes con cáncer siempre presentarán un puntaje PESI simplificado alto y serán considerados de mayor riesgo. Existe información limitada respecto de si los pacientes con PESI intermedio o alto (≥86 puntos) y cáncer activo, tienen mayor riesgo de presentar una evolución desfavorable respecto de aquellos sin cáncer. Objetivos: Determinar si, en pacientes con TEP y un puntaje PESI ≥86 puntos, la presencia de cáncer activo se asocia a una evolución desfavorable respecto de aquellos sin cáncer. Material y métodos: Análisis retrospectivo en pacientes con TEP y un puntaje PESI ≥86, entre los años 2008 y 2022. Se evaluó la ocurrencia de muerte intrahospitalaria (MIH), uso de drogas vasopresoras (DV) y necesidad de asistencia respiratoria mecánica (ARM) en los pacientes con vs. sin cáncer. Resultados: Se analizaron 209 pacientes. La población con cáncer, respecto de aquella sin cáncer, resultó ser más joven (65 vs. 70 años; p=0,006), presentó valores de PESI simplificado altos con mayor frecuencia (100 % vs. 84 %; p<0,001), tuvo menor requerimiento de ARM (9 % vs. 34 %; p=0,005) y menor uso de DV (11 % vs. 23 %; p=0,019), aunque no se observaron dife rencias en las tasas de MIH (12,7 % vs. 8 %; p=NS). Conclusiones: Los pacientes con TEP y un puntaje PESI ≥86 con cáncer no presentaron mayor MIH e incluso tuvieron menor requerimiento de ARM y DV. En la población estudiada, los pacientes con TEP y cáncer no tuvieron mayor riesgo de presentar una evolución desfavorable.

ABSTRACT Background: The Pulmonary Embolism Severity Index (PESI) is used to categorize the risk of death in acute pulmonary em bolism (PE). By definition, cancer patients will always have a high simplified PESI score and will be considered at high risk. There is limited information regarding whether patients with an intermediate or high PESI score (≥86 points) and cancer are at greater risk of an unfavorable progression versus those without cancer. Objectives: To determine whether the presence of active cancer in patients with a PESI score ≥86 points is associated with an unfavorable progression versus those without cancer. Methods: A retrospective analysis in patients with PE and a PESI score ≥86, between 2008 and 2022. The occurrence of in-hospital mortality (IHM) the use of vasopressor drugs (VDs), and the need for mechanical ventilatory support (MVS) were evaluated in patients with vs. without cancer. Results: 209 patients were analyzed. The population with cancer was younger than patients without cancer (65 vs 70 years; p=0.006), showed high simplified PESI values more frequently (100% vs 84%; p<0.001), had lower MVS requirement (9% vs 34%; p=0.005), and used fewer VDs (11% vs 23%; p=0.019). However, no difference was observed in IHM rates (12.7% vs 8%; p=NS). Conclusions: Patients with PE and a PESI score ≥86 who have cancer did not show higher IHM and also had lower MVS and VDs requirement. Therefore, in the studied population, patients with PE and cancer had no greater risk of having an unfavorable progression.

RESUMO

ABSTRACT Background: Pan-immuno-inflammation value is a new and comprehensive index that reflects both the immune response and systemic inflammation in the body. Objective: The aim of this study was to investigate the prognostic relevance of pan-immuno-inflammation value in predicting in-hospital mortality in acute pulmonary embolism patients and to compare it with the well-known risk scoring system, pulmonay embolism severity index, which is commonly used for a short-term mortality prediction in such patients. Methods: In total, 373 acute pulmonary embolism patients diagnosed with contrast-enhanced computed tomography were included in the study. Detailed cardiac evaluation of each patient was performed and pulmonary embolism severity index and pan-immuno-inflammation value were calculated. Results: In total, 60 patients died during their hospital stay. The multivariable logistic regression analysis revealed that baseline heart rate, N-terminal pro-B-type natriuretic peptide, lactate dehydrogenase, pan-immuno-inflammation value, and pulmonary embolism severity index were independent risk factors for in-hospital mortality in acute pulmonay embolism patients. When comparing with pulmonary embolism severity index, pan-immuno-inflammation value was non-inferior in terms of predicting the survival status in patients with acute pulmonay embolism. Conclusion: In our study, we found that the PIV was statistically significant in predicting in-hospital mortality in acute pulmonay embolism patients and was non-inferior to the pulmonary embolism severity index.

RESUMO

Onychomycosis is the most frequent nail disorder, but unfortunately, curative treatment is still a challenge, and commonly the infection recurs. A widely disseminated system to accurately assess and classify the severity of this disease, such as the MASI score for melasma or PASI for psoriasis, is lacking in the literature. In 2011, Carney et al. established and successfully validated the Onychomycosis Severity Index (OSI), proving it to be a simple and reproducible tool. To validate the Onychomycosis Severity Index in a Brazilian population. Four experienced dermatologists were taught how to use the OSI system, and then evaluated photographs of 24 nails. There was no consultation between the dermatologists, and the results were evaluated by an impartial third party. A statistically significant (p<0.001) high degree of agreement was observed between the evaluators and overall OSI score (mild, moderate or severe) as well as its subcategories (area of involvement, proximity to the nail matrix and presence of dermatophytoma or hyperkeratosis). OSI is a very useful tool to improve the clinical assessment of onychomycosis and support clinical trial inclusion criteria (p<0.001). It also provides important prognostic data and allows for a better follow-up of treatment efficacy.

RESUMO

OBJECTIVE: The objective of this study was to evaluate the agreement of smartwatch-derived single-lead electrocardiogram (ECG) recordings with 12-lead ECGs for diagnosing electrocardiographic abnormalities. STUDY DESIGN: A 12-lead ECG and an ECG using Apple Watch were obtained in 110 children (aged 1 week to 16 years) with normal (n = 75) or abnormal (n = 35) 12-lead ECGs (atrioventricular block [7], supraventricular tachycardia [SVT] {5}, bundle branch block [12], ventricular preexcitation [6], long QT [5]). In children aged <6 years, the ECG recording was performed with the active participation of an adult who applied the neonate or child's finger to the crown of the watch. In older children, tracings were obtained after brief teaching without adult guidance. All 12-lead ECGs were independently evaluated by 2 blinded cardiologists. Apple Watch ECGs were independently evaluated by another blinded cardiologist. RESULTS: In 109 children (99.1%), the smartwatch tracing was of sufficient quality for evaluation. Smartwatch tracings were 84% sensitive and 100% specific for the detection of an abnormal ECG. All 75 normal tracings were correctly identified. Of the 35 children with abnormalities on 12-lead ECGs, 5 (14%) were missed, most often because of baseline wander and artifacts. Rhythm disorders (atrioventricular block or SVT) and bundle branch blocks were correctly detected in most cases (11 of 12 and 11 of 12, respectively); preexcitation and long QT was detected in 4 of 6 and 4 of 5, respectively. CONCLUSION: Smartwatch ECGs recorded with parental assistance in children aged up to 6 years and independently in older children have the potential to detect clinically relevant conditions.

RESUMO

Substance use disorder (SUD) assessment and measurement in Brazil, as well as in many other countries, face significant shortcomings. The Measurement in the Addictions for Triage and Evaluation (MATE) was developed as a public domain tool, drawing from validated scales and incorporating World Health Organization International Classification of Functioning, Disability, and Health (ICF) framework. The Brazilian version of the MATE (MATE-pt-BR) was evaluated for its reliability and validity, with a total of 239 subjects participating in the study, and data collected between 11/01/2021 and 09/01/2022. The majority were male (79.2%), with diverse racial backgrounds. The substances most prevalently used in the last 30 days were. Alcohol (73.2%), nicotine (63.6%), and cocaine (44.2%). The mean scores for MATE modules showed variations, with Module Q2 assessing psychological well-being having high internal consistency (Cronbach's alpha = 0.92). MATE-pt-BR demonstrated robust internal consistency, with Module 6 (personality) and Module 2 (medical and psychiatric consultation indicators) being exceptions. MATE-pt-BR exhibited significant correlations among its sections and strong discriminant validity. Moreover, the paper compares MATE-pt-BR with the Addiction Severity Index (ASI-6), which is considered the gold-standard measure for SUD assessments. MATE-pt-BR offers a valuable tool for assessing substance use and related functional impairments in the Brazilian context.

RESUMO

Abstract BACKGROUND: Psoriasis is a systemic, immune-mediated disease characterized by inflammatory manifestations in the skin and joints. Vitamin D deficiency is currently considered a pandemic and is associated with comorbidities including psoriasis and psoriatic arthritis (PsA). OBJECTIVES: To determine the prevalence of hypovitaminosis D [25(OH)D] in patients with plaque psoriasis, with and without PsA, and of independent predictors of serum 25(OH)D levels. DESIGN AND SETTING: Retrospective cross-sectional study conducted among 300 patients at an outpatient clinic in a university center in Juiz de Fora, Minas Gerais, Brazil. METHODS: Demographic and clinical data (psoriasis area and severity index [PASI], family history, age at onset, disease duration, and the presence of PsA according to Classification Criteria for Psoriatic Arthritis), skin phototype, and season of the year were reviewed. RESULTS: Hypovitaminosis D (< 30 ng/mL) was highly prevalent in patients with psoriasis with and without PsA (82.2% and 74.9%, respectively). An inverse correlation between PASI and vitamin D was found (without PsA r = -0.59 and, PsA r = -0.52, P < 0.001), and multivariate regression revealed that hypovitaminosis D was associated with disease severity, season, and phototype. It was confirmed by binary logistic regression between PASI and vitamin D deficiency (< 30 ng/mL), (odds ratio, OR 1.78 CI: -0.20-0.53, P < 0.001). CONCLUSION: Hypovitaminosis D (< 30 ng/mL) was highly prevalent in psoriatic patients with and without PsA. Season and skin phototype were associated with 25(OH)D levels. An inverse association between PASI and serum 25(OH)D levels was established.

RESUMO

BACKGROUND: Psoriasis is a chronic disease that seriously impacts quality of life. There are known genetic and environmental factors that influence its onset and progression. Even though there is no cure for it, there are a variety of treatments available today to control its symptoms, although many of them fail to do so substantially. OBJECTIVE: To identify the association of multiple sociodemographic, clinical, and pharmacological factors with therapeutic failure. METHODS: Observational, descriptive, cross-sectional, retrospective, and analytical study of therapeutic failure in patients with moderate or severe psoriasis between 2020 and 2021 was performed. RESULTS: In total 1051 patients with moderate or severe psoriasis were evaluated. Gender (ORa: 0.579 CI 95%: 0.382-0.878), type of therapy (biologic or non-biologic; ORa: 1.939 CI 95%: 1.242-3.027), age (ORa: 1.018 CI 95%: 1.003-1.034), days of treatment (ORa: 1 CI 95%: 0.999-1) and DLQI (ORa: 1.212 CI 95%: 1.172-1.253) are significantly associated with therapeutic failure. CONCLUSION: Being male and receiving biologic therapy are associated with a higher incidence of therapeutic failure in the treatment of moderate or severe psoriasis. The increase in DLQI increase in the probability of failure, and mayor age or days of treatment decrease in the probability of failure.

RESUMO

OBJECTIVE: The purpose of this study was to asess the efficacy of an intensive outpatient treatment (IOT) for substance use disorder (SUD) using a multidimensional approach. METHODS: All the patients consecutively admitted to a private institution between May 2019 and May 2020 were invited to participate in the study. The program consisted in a 12-month set of psychosocial, medical and recreative interventions requiring an attendance of at least 9 hours per week. Efficacy was evaluated at admission and every three months by the Addiction Severity Index (ASI). Quality of life was evaluated at admission and at the end of the treatment by the WHOQOL-Bref questionnaire. A comparison of parameters obtained at admission between the group that completed and the one that abandonned the treatment was also performed to detect potential predictors of early dropout. Six months after the end of the treatment, the participants were contacted in order to repeat an evaluation through the ASI and the WHOQOL-Bref scales. RESULTS: 41 participants (73% male, age 42.8 ± 16 years) were included. 14 participants dropped out at a median time of 88 days. Among those who completed the treatment improvements were observed in different clinical dimensions: in alcohol and drug consumption (3 months), in medical problems (6 months), in family/social relationships (9 months), in psychological scores (12 months) and in the four dimensions of WHOQOL-Bref. No changes were observed in legal problems and in the employment status. Only legal problems and family/social relationships at admission were significantly different among patients who completed versus those who dropped-out. Six months after discharge, no differences in WHOQOL-Bref scores were observed in the 15 participants who could be located and accepted the assessment. A little but statistically significant worsening was observed in the psychological problems dimension of the ASI in post-discharge follow-up. The rest of the ASI dimensions remained unchanged 6 months after concluding the treatment. CONCLUSION: This is one of the few studies performed in a latinamerican setting assessing the efficacy of a long-term IOT for SUD. It confirms previous works from developed countries, showing the potential benefits of IOTs implementation in our region.

OBJETIVO: Evaluar la eficacia de un tratamiento ambulatorio intensivo (TAI) para el trastorno por uso de sustancias (TUS) utilizando un enfoque multidimensional.

RESUMO

Geographic tongue (GT) is a chronic condition of unknown aetiology, with no defined parameters to establish the protocol for evidence-based management. Validation of a newly developed and proposed clinical index to assess the severity of GT could assist in its diagnosis, especially in cases associated with systemic dermatological diseases in the form of psoriasis. OBJECTIVE: To verify the applicability of the geographic tongue area and severity index (GTASI). This involved healthcare professionals from different specialties to evaluate the usefulness of the GTASI in supporting GT classification, as well as the follow-up process. METHODS: One hundred cases of previously diagnosed GT were initially evaluated by three independent, experienced researchers/clinicians to obtain a standardised classification baseline. Subsequently, nine cases of GT were selected, three cases for each category-mild, moderate and severe. These stages were professionally evaluated by 51 healthcare professionals from three groups: 17 dentists (33%), 22 oral medicine specialists (43%) and 12 specialist dermatologists (24%) during a cross-sectional survey. RESULTS: The quantitative and qualitative assessment based on experts' opinions in the cross-sectional survey demonstrated an acceptable, similar level of GT clinical diagnosis (p > 0.05), with coherence between the various groups of professionals critically appraising the GTASI. An apparent divergence was observed for the moderate GT category, as well as in the group of less experienced evaluators. CONCLUSION: Whilst the validation of GTASI applicability was successfully executed, the general dental practitioners, specialists in oral medicine and dermatologists were equally capable of correct GT diagnosis and appropriately rating its severity. These coherent results were especially replicated among the experienced clinicians. The validation of the newly proposed index confirmed its reliability as a feasible instrument in oral medicine, with the prospect of its wider implementation in clinical practice.

RESUMO

Forecasting the severity of plant diseases is an emerging need for farmers and companies to optimize management actions and to predict crop yields. Process-based models are viable tools for this purpose, thanks to their capability to reproduce pathogen epidemiological processes as a function of the variability of agro-environmental conditions. We formalized the key phases of the life cycle of Puccinia kuenhii (W. Krüger) EJ Butler, the causal agent of orange rust on sugarcane, into a new simulation model, called ARISE (Orange Rust Intensity Index). ARISE is composed of generic models of epidemiological processes modulated by partial components of host resistance and was parameterized according to P. kuenhii hydro-thermal requirements. After calibration and evaluation with field data, ARISE was executed on sugarcane areas in Brazil, India and Australia to assess the pathogen suitability in different environments. ARISE performed well in calibration and evaluation, where it accurately matched observations of orange rust severity. It also reproduced a large spatial and temporal variability in simulated areas, confirming that the pathogen suitability is strictly dependent on warm temperatures and high relative air humidity. Further improvements will entail coupling ARISE with a sugarcane growth model to assess yield losses, while further testing the model with field data, using input weather data at a finer resolution to develop a decision support system for sugarcane growers.

RESUMO

INTRODUCTION: In 2016, the Ministry of Health in Jamaica selected the Emergency Severity Index as the triage tool to be used nationally. This study evaluated the effectiveness of this approach by assessing the interrater reliability among new users trained with minimal resources by 2 experienced trainers, 1 local and 1 international. METHODS: A retrospective case series review was conducted within an online learning collaborative framework. After completion of the training, the participants from each of the 19 clinical sites were asked to submit 2 triage cases per month for blinded review by the expert trainers. The triage categories assigned by each reviewer were compared with those assigned by the newly trained Emergency Severity Index providers. A weighted kappa value was calculated to assess the degree of agreement between the sites and the expert trainers. RESULTS: A total of 166 cases were received over the study period. Participation in the learning collaborative was consistently below 50%. The interrater reliability between the expert trainers (κ = 0.48) as well as between each scorer and each accident and emergency department site (κSF = 0.33, κPT = 0.26) was low, although there was improvement over the study period. Incomplete triage documentation limited raters' ability to assign triage categories and assess interrater reliability. DISCUSSION: Despite a rigorous implementation process, the interrater reliability of the Emergency Severity Index skills of Jamaican emergency nurses and doctors when compared with that of the 2 experts was poor. Several areas were identified for strengthening. Considerations for the implementation of the Emergency Severity Index in countries outside of the US were also discussed.

RESUMO

RESUMEN El Mal de Río Cuarto (MRC) es una de las enfermedades virales más importantes del maíz en Argentina. El índice de severidad de enfermedad (ISE) permite combinar la incidencia y la severidad de una enfermedad en una métrica única. La reacción genotípica a MRC ha sido muy estudiada en poblaciones biparentales, sin embargo este carácter complejo no se ha analizado mediante estudios de mapeo por asociación. El objetivo del presente trabajo es identificar nuevos alelos de resistencia asociados con el ISE de la enfermedad MRC de maíz en un germoplasma exótico del Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT). Una población de líneas de maíz del CIMMYT se evaluó fenotípicamente en ambientes donde la enfermedad es endémica. Los predictores del efecto genotípico (BLUP, best linear unbiased predictor) del ISE de MRC y 78.376 marcadores SNP (Single Nucleotide Polymorphism) se usaron para realizar el mapeo por asociación en 186 líneas de maíz. Los componentes de varianza y los valores de heredabilidad sugieren una amplia variabilidad genotípica en la población de líneas. El mapeo por asociación permitió identificar 11 posibles QTL de resistencia a MRC. La incorporación de germoplasma exótico en los programas de mejoramiento de maíz locales podría contribuir favorablemente a la creación de genotipos híbridos con mayor nivel de resistencia a MRC. La capacidad predictiva de los marcadores asociados con la resistencia a MRC indican que la selección asistida por marcadores es una herramienta recomendable para seleccionar genotipos resistentes a MRC.

ABSTRACT Mal de Río Cuarto (MRC) is one of the most important viral diseases of maize in Argentina. The disease severity index (DSI) allows to combine the incidence and severity of a disease in a single metric. The genotypic reaction to MRC has been extensively studied in biparental populations. However, this complex trait has not been analyzed by genome-wide association studies (GWAS). The aim of this work is to identify new resistance alleles associated with DSI of MRC in an exotic germplasm from the International Maize and Wheat Improvement Center (CIMMYT). A population of maize lines from CIMMYT was phenotypically evaluated in environments in the area where the disease is endemic. The predictors of genetic effects (BLUP, best linear unbiased predictor) and 78,376 SNP markers (Single Nucleotide Polymorphism) were used to perform the GWAS in 186 maize lines. The values of variance components and mean-basis heritability suggest a wide genotypic variability in the population. The GWAS allowed to identify 11 putative QTL of resistance to MRC. The incorporation of exotic germplasm into local maize breeding programs could contribute favorably to the creation of hybrids with a higher level of resistance to MRC. The predictive ability of associated markers with MRC resistance indicates that marker-assisted selection is an advisable tool for selecting MRC resistant genotypes.

RESUMO

Abstract Subclinical ventilatory dysfunction is observed in individuals with spinocerebellar ataxias (SCA). No studies have correlated ventilatory dysfunction to clinical and functional decline in SCA2. Objective: To evaluate the relationship between the values of peak expiratory flow (PEF), maximum inspiratory pressure (MIP), and presence of respiratory complaints with age, disease duration, age at onset of symptoms, balance scores, independence in basic (ADL) and instrumental (IADL) Activities of Daily Living (ADLs), and severity of ataxia (SARA) in individuals with SCA2. Methods: Cross-sectional study evaluating age, disease duration, age at onset of symptoms, scores in the Berg Balance Scale and in the SARA, Functional Independence Measure and Lawton's scale, values of PEF and MIP, and the presence of respiratory complaints. Results: The study included 36 individuals with SCA2, with a mean age of 42.5±2.4 years, disease duration of 7.6±8.2 years, age 33.7±11.5 years at onset of symptoms, and 9.9±10.3 points in the SARA scale. The lowest PEF values correlated with the longer disease duration (p=0.021). The lowest values of PEF and MIP correlated with greater balance impairment (p=0.019 and p=0.045, respectively), increased degree of dependence in the ADL (p=0.006 and p=0.050, respectively) and IADL (p=0.003 and p=0.001, respectively) scales, and highest severity of ataxia (p=0.00 and p=0.017, respectively). Respiratory complaints were observed in 12 (33.3%) individuals and were not related to age, disease duration, age at onset of symptoms, balance, independence, ataxia severity, or PEF and MIP values. Conclusion: Ventilatory dysfunction, even when asymptomatic, is related to balance impairment, independence, and ataxia severity in individuals with SCA2.

Resumo Disfunção ventilatória subclínica tem sido observada em indivíduos com ataxias espinocerebelares (SCA). Não existem estudos relacionando disfunção ventilatória ao declínio clínico e funcional na SCA2. Objetivo: Avaliar a relação dos valores de Pico de Fluxo Expiratório (PFE), Pressão Inspiratória Máxima (PIMAX) e presença de queixas respiratórias com idade, tempo de doença, idade de início dos sintomas, escore de equilíbrio, independência para atividades básicas (AVD) e instrumentais (AIVD) de vida diária e gravidade da ataxia (SARA) em indivíduos com SCA2. Métodos: Estudo transversal, considerando: idade, tempo de doença, idade de início dos sintomas, escores nas Escalas SARA, Equilíbrio de Berg, Medida da Independência Funcional e de Lawton, valores de PFE, PIMAX e queixas respiratórias. Resultados: Foram avaliados 36 indivíduos com SCA2 com média de 42,5±2,4) anos de idade, 7,6±8,2 anos de tempo de doença, 33,7±11,5 anos de idade de início dos sintomas e 9,9±10,3 pontos na escala SARA. Os menores valores de PFE estiveram relacionados ao maior tempo de doença (p=0,021). Os menores valores de PFE e PIMAX estiveram relacionados ao maior comprometimento do equilíbrio (p=0,019; p=0,045, respectivamente), maior dependência para ADV (p=0,006; p=0,050, respectivamente) e AIVD (p=0,003; p=0,001, respectivamente) e maior gravidade da ataxia (p=0,006; p=0,017, respectivamente). Foram observadas queixas respiratórias em 12 (33,3%) indivíduos que não estiveram relacionadas à idade, idade de início dos sintomas, tempo de doença, equilíbrio, independência, gravidade da ataxia, ou valores de PFE e PIMAX. Conclusão: A disfunção ventilatória, mesmo quando assintomática, está relacionada ao comprometimento do equilíbrio, à independência e à gravidade da ataxia em indivíduos com SCA2.

RESUMO

BACKGROUND: Fabry disease (FD) is a lysosomal disease in which mutations affect the GLA gene located on the X chromosome. The defective product, the enzyme alpha-galactosidase A, causes accumulation of substrate and contributes to the disruption of cell function in several organs, with variable severity and consequent damage of tissue or organ function. Patient reported outcomes (PROs) enable patients to provide information regarding the consequences of their disease and its treatment and are often recognized as the most important outcomes for them. OBJECTIVES: To evaluate pain, depression, sleep disturbances, disability and disease impact on quality of life in a cohort of Brazilian FD patients and compare between groups stratified by the Mainz Symptom Severity Index (MSSI) Methods: Thirty-seven genotype confirmed classic FD patients - 16 male and 21 female - (mutations: C142R, A156D, L180F, R227X, W262X, G271A, P293S, Y264SX) were evaluated and answered the following questionnaires: Brief Pain Inventory (BPI), Hamilton Depression Rating Scale (HAM-D), Pittsburgh Sleep Quality Index (PSQI), Health Assessment Questionnaire Disability Index (HAQ-DI), Short-Form Health Survey 36 (SF-36). RESULTS: In FD patients, mean ± SD BPI severity result was 2.78 ± 2.66 for severe; 2.80 ± 2.55 for moderate and 1.55 ± 2.38 for mild severity patients. Mean ± SD BPI interference result was 2.55 ± 2.44 for severe; 2.80 ± 3.18 for moderate and 1.36 ± 2.83 for mild patients. BPI severity and interference values correlated with MSSI scores (r = 0.24; p < .001 / r = 0.25; p < .001). Application of HAM-D indicated depression in 21 patients (56.8%). HAM-D results had positive correlation with MSSI values (r = 0.21; p < .001), with BPI severity (r = 0.54; p < .001) and interference (r = 0.65; p < .001). PSQI depicted sleep disturbances in 22 patients (59.5%). PSQI values correlated with MSSI values (r = 0.25; p < .001), with HAM-D results (r = 0.65; p < .001) and BPI severity (r = 0.47; p < .001) and interference (r = 0.66; p < .001). Mean HAQ-DI result was 0.490 for severe; 0.274 for moderate and 0.157 for mild severity patients. CONCLUSIONS: Depression, sleep disturbances and disability were under-recognized in FD patients. HAQ-DI revealed worse disability according to MSSI severity status. The lowest raw scores from the SF-36 questionnaire were for the domains general health perception and physical role functioning. Standardized assessments should be routine care and started as early as diagnosis of Fabry disease is made.
