Screening for cognitive impairment in systemic lupus erythematosus: Application of the Montreal Cognitive Assessment (MoCA) in a Greek patient sample.

BACKGROUND: Cognitive impairment (CI) is one of the most frequent neuropsychiatric manifestations of systemic lupus erythematosus (SLE). Given that extensive neuropsychological testing is not always feasible in routine clinical practice, brief cognitive screening tools are desirable. The aim of this study was to evaluate the Montreal Cognitive Assessment (MoCA) as a screening tool for CI in SLE. METHODS: Consecutive SLE patients followed at a single centre were evaluated using MoCA and an extensive neuropsychological test battery (NPT), including the Digits Forward and Digits Backwards, Rey Auditory Verbal Learning Memory Test, Trail Making Test, Stroop Colour-Word Test, Semantic and Phonetic Verbal Fluency tests and a 25-problem version of the General Adult Mental Ability test. The criterion validity of MoCA was assessed through receiver operating characteristic (ROC) analyses using three different case definitions: i) against normative population data, ii) and iii) against average performance of a comparison group of rheumatoid arthritis (RA) patients, to adjust for possible confounding effects of chronic illness and inflammatory processes on cognitive performance. The effect of patient-related (age, years of education, anxiety, depression, fatigue and pain) and disease-related (activity, damage, age at diagnosis, disease duration, use of glucocorticoid, psychotropic and pain medication) parameters on the MoCA was examined. RESULTS: A total of 71 SLE patients were evaluated. MoCA significantly correlated with all NPT scores and was affected by education level (p < 0.001), but not by other demographic or clinical variables. The optimal cutoff for detecting CI, as defined on the basis of normative population data, was 23/30 points, demonstrating 73% sensitivity and 75% specificity. A cutoff of 22/30 points, using neuropsychological profiles of the RA group as inflammatory disease controls, exhibited higher sensitivity (100%, based on both definitions) and specificity (87% and 90%, depending on the definition). The standard cutoff of 26/30 points displayed excellent sensitivity (91-100%) with significant expenses in specificity (43-45%). CONCLUSION: The MoCA is an easily applied tool, which appears to be reliable for identifying CI in SLE patients. The standard cutoff score (26/30) ensures excellent sensitivity while lower cutoff scores (22-23/30) may, also, provide higher specificity.

In an early SLE cohort the ACR-1997, SLICC-2012 and EULAR/ACR-2019 criteria classify non-overlapping groups of patients: use of all three criteria ensures optimal capture for clinical studies while their modification earlier classification and treatment.

OBJECTIVES: Classification criteria are biased towards classifying long-standing disease. We compared the European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR)-2019, Systemic Lupus International Collaborating Clinics (SLICC)-2012 and ACR-1997 criteria in an early (median 48 months) systemic lupus erythematosus (SLE) cohort. METHODS: Patients diagnosed with SLE (n=690) or control diseases (n=401). Sensitivity, specificity of the criteria and time-to-classification were calculated. Modified classification algorithms were derived from a random 80% and validated in the remaining 20% of the dataset running multiple iterations. RESULTS: At last assessment, sensitivities of ACR-1997, SLICC-2012 and EULAR/ACR-2019 criteria were 85.7%, 91.3% and 88.6%, with specificities 93.0%, 93.8% and 97.3%, respectively. Both SLICC and EULAR/ACR enabled earlier classification. Only 76.7% of patients with SLE met all three criteria suggesting non-overlapping groups. Notably, unclassified patients had high prevalence of British Isles Lupus Assessment Group moderate/severe manifestations (43.3%-60%) and SLICC/ACR organ damage (30%-50%). At diagnosis, criteria missed 25.6%-30.5% of patients. Modification of EULAR/ACR and SLICC algorithms to include hypocomplementaemia and/or positive anti-phospholipid antibodies as alternative entry criterion, and/or allow classification with fewer clinical criteria from multiple organs, increased their sensitivity at diagnosis (median 82.0% and 86.2%) and overall (93.7% and 97.1%) with modest decreases in specificity. Importantly, patients who were still missed by the modified criteria had lower incidence of major organ involvement, use of immunosuppressive/biological therapies and organ damage. CONCLUSIONS: The SLICC and EULAR/ACR are more sensitive than the ACR and the EULAR/ACR criteria have superior specificity in early SLE, although patients with significant disease can be missed. Combination and/or modification of the classification algorithms may enhance their sensitivity, allowing earlier classification and treatment of more patients with high disease burden.

Combined genetic and transcriptome analysis of patients with SLE: distinct, targetable signatures for susceptibility and severity.

OBJECTIVES: Systemic lupus erythematosus (SLE) diagnosis and treatment remain empirical and the molecular basis for its heterogeneity elusive. We explored the genomic basis for disease susceptibility and severity. METHODS: mRNA sequencing and genotyping in blood from 142 patients with SLE and 58 healthy volunteers. Abundances of cell types were assessed by CIBERSORT and cell-specific effects by interaction terms in linear models. Differentially expressed genes (DEGs) were used to train classifiers (linear discriminant analysis) of SLE versus healthy individuals in 80% of the dataset and were validated in the remaining 20% running 1000 iterations. Transcriptome/genotypes were integrated by expression-quantitative trail loci (eQTL) analysis; tissue-specific genetic causality was assessed by regulatory trait concordance (RTC). RESULTS: SLE has a 'susceptibility signature' present in patients in clinical remission, an 'activity signature' linked to genes that regulate immune cell metabolism, protein synthesis and proliferation, and a 'severity signature' best illustrated in active nephritis, enriched in druggable granulocyte and plasmablast/plasma-cell pathways. Patients with SLE have also perturbed mRNA splicing enriched in immune system and interferon signalling genes. A novel transcriptome index distinguished active versus inactive disease-but not low disease activity-and correlated with disease severity. DEGs discriminate SLE versus healthy individuals with median sensitivity 86% and specificity 92% suggesting a potential use in diagnostics. Combined eQTL analysis from the Genotype Tissue Expression (GTEx) project and SLE-associated genetic polymorphisms demonstrates that susceptibility variants may regulate gene expression in the blood but also in other tissues. CONCLUSION: Specific gene networks confer susceptibility to SLE, activity and severity, and may facilitate personalised care.

In early arthritis patients, high HAQ at baseline and DAS28 at three months predict suboptimal outcomes at two years: a retrospective cohort study.

OBJECTIVES: Early arthritis clinics (EAC) aim to improve rheumatoid arthritis (RA) outcomes by tailoring treatment targeting to remission. Our aim was to analyse disease course and relevant predictors over 2 years in early arthritis; we also assessed the applicability of the "treat-to-target approach" in a real-life EAC. METHODS: Patients with early arthritis recruited at the EAC of the University Hospital of Heraklion were followed prospectively according to a follow-up protocol for two years, without implementing a pre-specified treatment protocol, to capture real-life practices. Early predictors of "suboptimal outcomes" (high disease activity or HAQ>1.0 at 2 years) and biologic DMARD (bDMARD) initiation were evaluated with multivariate logistic regression. Intensification of treatment at 3 and 6 months and subsequent long-term outcome were also assessed. RESULTS: 251 patients [RA (n=188), undifferentiated arthritis (n=63)] were included. Although both DAS28 and HAQ at 2 years improved significantly compared to baseline in RA patients [mean (SD) DAS28 and median (IQR) HAQ 3.70 (1.32) and 0.44 (0.75) at 2 years, p<0.001 for both compared to baseline], 43.7% still had moderate and 18.8% high disease activity. The most powerful predictor of suboptimal outcomes or bDMARD initiation in RA was high disease activity at three months (adjusted odds ratio 2.22 and 2.62, respectively). At three and six months 72.8% and 62.4% of patients with medium/high disease activity received treatment intensification, which resulted in significant decrease in disease activity at 2 years (p<0.001 for ΔDAS28). CONCLUSIONS: DAS28 at three months was the most powerful predictor of suboptimal disease outcome during a 2-year follow-up in early RA. Despite significant DAS reductions, more than 50% of patients have active disease at two years. Failure to fully implement the treat-to-target strategy in our cohort could account for the low remission rates.

Adaptation to inflammatory rheumatic disease: Do illness representations predict patients' physical functioning over time? A complex relationship.

Patients with an inflammatory rheumatic disease (IRD), are often faced with significant limitations in physical functioning. Illness representations are a key-factor of their illness-related experience. Our aim was to examine (a) whether illness representations can predict or only reflect IRD patients' physical functioning over time, and (b) the specific pathways through which representations and physical functioning at baseline are associated with representations and functioning at follow-up. Patients with rheumatoid arthritis (N = 54) or systemic lupus erythematosus (N = 58) participated in the two phases of the study, 1 year apart. According to the results, illness representations were rather predicted by physical functioning than the other way around. At the same time, illness representations at baseline and at follow-up seemed to form a chain that mediated the relation between physical functioning at baseline and 1 year later. These findings may help us better delineate the interplay between the ways patients understand their condition and adaptation to illness.

Epidemiology and burden of systemic lupus erythematosus in a Southern European population: data from the community-based lupus registry of Crete, Greece.

OBJECTIVES: Several population-based studies on systemic lupus erythematosus (SLE) have been reported, yet community-based, individual-case validated, comprehensive reports are missing. We studied the SLE epidemiology and burden on the island of Crete during 1999-2013. METHODS: Multisource case-finding included patients ≥15 years old. Cases were ascertained by the ACR 1997, SLICC 2012 criteria and rheumatologist diagnosis, and validated through synthesis of medical charts, administrative and patient-generated data. RESULTS: Overall age-adjusted/sex-adjusted incidence was 7.4 (95% CI 6.8 to 7.9) per 100 000 persons/year, with stabilising trends in women but increasing in men, and average (±SD) age of diagnosis at 43 (±15) years. Adjusted and crude prevalence (December 2013) was 123.4 (113.9 to 132.9) and 143 (133 to 154)/105 (165/105 in urban vs 123/105 in rural regions, p<0.001), respectively. Age-adjusted/sex-adjusted nephritis incidence was 0.6 (0.4 to 0.8) with stable trends, whereas that of neuropsychiatric SLE was 0.5 (0.4 to 0.7) per 100 000 persons/year and increasing. Although half of prevalent cases had mild manifestations, 30.5% developed organ damage after 7.2 (±6.6) years of disease duration, with the neuropsychiatric domain most frequently afflicted, and 4.4% of patients with nephritis developed end-stage renal disease. The ACR 1997 and SLICC 2012 classification criteria showed high concordance (87%), yet physician-based diagnosis occurred earlier than criteria-based in about 20% of cases. CONCLUSIONS: By the use of a comprehensive methodology, we describe the full spectrum of SLE from the community to tertiary care, with almost half of the cases having mild disease, yet with significant damage accrual. SLE is not rare, affects predominantly middle-aged women and is increasingly recognised in men. Neuropsychiatric disease is an emerging frontier in lupus prevention and care.

Practice Recommendations for the Management of MASLD in Primary Care: Consensus Results.

BACKGROUND: Despite its high prevalence and impact on health, metabolic dysfunction-associated steatotic liver disease (MASLD) is inadequately addressed in European primary care (PC), with a large proportion of cases going undiagnosed or diagnosed too late. A multi-country European research consortium led a project to design and evaluate a patient-centered, integrated model for MASLD screening, diagnosis, and linkage to specialty care for European PC settings. Based on the lessons from this project, the latest research evidence, and existing guidelines for the management of MASLD, we sought to develop a set of practice recommendations for screening, referral, and management of MASLD in PC. METHODS: The Rand/UCLA modified Delphi panel method, with two rounds, was used to reach consensus on practice recommendations. The international panel consisted of experts from six countries, representing family medicine, gastroenterology, hepatology, cardiology, and public health. Initially, fifteen statements were drafted based on a synthesis of evidence from the literature and earlier findings from our consortium. Prior to the consensus meeting, the statements were rated by the experts in the first round. Then, in a hybrid meeting, the experts discussed findings from round one, adjusted the statements, and reassessed the updated recommendations in a second round. RESULTS: In round one, there was already a high level of consensus on 10 out of 15 statements. After round 2, there were fourteen statements with a high degree of agreement (>90%). One statement was not endorsed. The approved recommendations addressed the following practice areas: risk screening and diagnosis, management of MASLD-lifestyle interventions, pharmacological treatment of MASLD/MASH, pharmacological treatment for co-morbidity, integrated care, surgical management, and other referrals to specialists. CONCLUSIONS: The final set of 14 recommendations focuses on increasing comprehensive care for MASLD in PC. The recommendations provide practical evidence-based guidance tailored to PC practitioners. We expect that these recommendations will contribute to the ongoing discussion on systematic approaches to tackling MASLD and supporting European PC providers by integrating the latest evidence into practice.

Development and implementation of a continuing medical education program on non-alcoholic fatty liver disease for primary care practitioners in Europe.

Background: Primary care has a crucial role to play in the prevention, early detection, referral, and risk factor management of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NAFLD/NASH). In 2021, a team of European collaborators developed a continuing medical education (CME) program on NAFLD/NASH that consolidates evidence and clinical best practices tailored to the primary care setting. This article reports on the methodology used to design and develop the CME and the results of a feasibility study. Methods: An expert advisory group representing both European specialists and general practitioners supported the design of the CME to be implemented in three European settings (Greece, Spain, and Netherlands). The CME features four training modules and problem-based learning using clinical case studies. The CME was tested regarding feasibility and acceptability among a sample of primary care providers (PCPs) in Greece (n = 28) with measurements occurring before, immediately after, and 1 month following the training. Outcome measures included satisfaction with the CME, changes in PCPs' knowledge, attitudes, confidence, and self-reported clinical practices related to NAFLD/NASH. Results: The CME is available as an open-access e-learning course on the European Society for Primary Care Gastroenterology education platform in English, Greek, Spanish, and Dutch. The feasibility study documented high levels of satisfaction, with 96% of PCPs reporting they were extremely or very satisfied with the overall training. Statistically significant increases in PCPs' confidence in NAFLD/NASH-related clinical practices were documented between the pre- and post-assessments. At the follow-up, 62% of GPs reported that the CME had changed their clinical practices related to NAFLD/NASH to a great extent. Conclusion: This CME intervention developed by experts and tailored to PCPs in European settings may serve as an asset for increasing knowledge, confidence, and practice behaviors related to NAFLD/NASH.

High Comorbidity Burden in Patients with SLE: Data from the Community-Based Lupus Registry of Crete.

Comorbidities and multimorbidity, often complicating the disease course of patients with chronic inflammatory rheumatic diseases, may be influenced by disease-intrinsic and extrinsic determinants including regional and social factors. We analyzed the frequency and co-segregation of self-reported comorbid diseases in a community-based Mediterranean registry of patients (n = 399) with systemic lupus erythematosus (SLE). Predictors for multimorbidity were identified by multivariable logistic regression, strongly-associated pairs of comorbidities by the Cramer's V-statistic, and comorbidities clusters by hierarchical agglomerative clustering. Among the most prevalent comorbidities were thyroid (45.6%) and metabolic disorders (hypertension: 24.6%, dyslipidemia: 33.3%, obesity: 35.3%), followed by osteoporosis (22.3%), cardiovascular (20.8%), and allergic (20.6%) disorders. Mental comorbidities were also common, particularly depression (26.7%) and generalized anxiety disorder (10.7%). Notably, 51.0% of patients had ≥3 physical and 33.1% had ≥2 mental comorbidities, with a large fraction (n = 86) displaying multimorbidity from both domains. Sociodemographic (education level, marital status) and clinical (disease severity, neurological involvement) were independently associated with physical or mental comorbidity. Patients were grouped into five distinct clusters of variably prevalent comorbid diseases from different organs and domains, which correlated with SLE severity patterns. Conclusively, our results suggest a high multimorbidity burden in patients with SLE at the community, advocating for integrated care to optimize outcomes.

Emotion regulation contributes to the well-being of patients with autoimmune diseases through illness-related emotions: A prospective study.

This prospective study aimed to examine whether illness-related negative emotions mediate the relationship of cognitive reappraisal and expressive suppression to the well-being of 99 patients with rheumatoid arthritis or multiple sclerosis. After adjusting for disease and patient-related parameters, only cognitive reappraisal was associated with physical and psychological well-being through emotions. Expressive suppression was associated with psychological well-being only for patients reporting less use of cognitive reappraisal. These results underscore the need for prospective studies that will investigate the long-term impact of emotion regulation on adaptation to chronic illness and the conditions under which this impact takes place.

Associations of sense of coherence and self-efficacy with health status and disease severity in COPD.

Sense of coherence and self-efficacy has been found to affect health-related quality of life in chronic diseases. However, research on respiratory diseases is limited. Here we report findings on quality of life (QoL) of COPD patients and the associations with coherence and self-efficacy. This study consists of the Greek national branch of the UNLOCK study, with a sample of 257 COPD patients. Coherence and self-efficacy are positively inter-correlated (Pearson rho = 0.590, p < 0.001). They are negatively correlated with the quality of life (CAT) [Pearson rho: coherence = -0.29, p < 0.001; self-efficacy = -0.29, p < 0.001) and mMRC (coherence = -0.37, p < 0.001; self-efficacy rho = -0.32, p < 0.001)]. Coherence is inversely associated with (Global Initiative for Chronic Obstructive Lung Disease) GOLD 2018-CAT and GOLD 2018-mMRC classification and "having at least one exacerbation in the past year". Findings are stressing the need for their incorporation in primary health care and COPD guidance as it maybe that enhancing coherence and self-efficacy will improve QoL.

Chronic obstructive pulmonary disease and rheumatic diseases: A systematic review on a neglected comorbidity.

BACKGROUND: Although, both chronic obstructive pulmonary disease (COPD) and rheumatic diseases (RDs) are common, and each has significant impact on patients' overall health/quality of life, their co-occurrence has received little attention, while 15% of COPD remains undiagnosed in RDs. OBJECTIVE: To update the information regarding the comorbid state of RD/COPD (prevalence, incidence), to examine whether patients with RD have increased risk of developing COPD and vice versa, and what implications this comorbidity has on patients' outcomes (mortality, hospitalizations, exacerbations). METHODS: We performed a systematic literature review regarding the comorbidity of an RD (rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), systemic lupus erythematosus (SLE), primary Sjogren syndrome disease (pSS), and systemic sclerosis (SSc)) with COPD. From 2803 reports retrieved, 33 articles were further screened. Finally, 27 articles were included. RESULTS: Robust evidence supports that COPD develops up to 68% more frequently in patients with RA, as compared to the general population. Similarly, COPD is increased in every other RD that was studied. Further, self-referred arthritis is more common in COPD patients versus non-COPD controls and a predictor of worst self-rated health status. Patients with inflammatory arthritis/COPD have increased mortality (threefold in RA-COPD, irrespectively of which is first diagnosed), hospitalizations, and emergency visits. CONCLUSION: COPD is more common in patients with RA, AS, PsA, SLE, pSS, and SSc; yet, the association, vice versa, warrants further investigation. Nevertheless, COPD/RDs coexistence has significant prognostic value for worst outcomes; therefore, awareness is required to track early identification, especially in primary care.

Assessing spirituality: is there a beneficial role in the management of COPD?

Here,we report on the role of spirituality assessment in the management of chronic obstructive pulmonary disease (COPD). Although a positive effect of addressing spirituality in health care has been proved in a number of chronic diseases, its potential in COPD has received less attention. Although limited, available evidence suggests that spirituality may play an important role in improving quality of life of patients with COPD. The fruitful results in other long-term conditions may lay the foundation for further research on addressing spirituality in COPD. This should focus where the burden of COPD is greatest, including low-resource settings globally. Implementation research should include exploration of an acceptable consultation process to identify patients who would welcome spiritual discussions; how to integrate spiritual approaches into health care professional curricula so that they are aware of its importance and have the confidence to raise it with patients and how to integrate spiritual approaches into holistic COPD care.

Systemic Lupus Erythematosus in Primary Care: An Update and Practical Messages for the General Practitioner.

Systemic Lupus Erythematosus (SLE) is a complex chronic autoimmune disease that manifests a wide range of organ involvement. Traditionally, the diagnosis and management of SLE is provided at secondary and tertiary centers to ensure prompt initiation of treatment, adequate control of flares and prevention of irreversible organ damage. Notwithstanding, the role of primary care in SLE is also emerging as there are still significant unmet needs such as the diagnostic delay at the community level and the high burden of therapy- and disease-related comorbidities. In the present review, we summarize practical messages for primary care physicians and general practitioners (GPs) concerning early diagnosis and proper referral of patients with SLE. In addition, we discuss the main comorbidities complicating the disease course and the recommended preventative measures, and we also provide an update on the role and current educational needs of GPs regarding the disease.

Update on the epidemiology, risk factors, and disease outcomes of systemic lupus erythematosus.

Obtaining an updated view of the epidemiology, risk factors, and prognosis of systemic lupus erythematosus (SLE) is pivotal to our understanding of the disease burden. Recent community-based studies with comprehensive methodology provided more accurate disease occurrence estimates and suggested that SLE may be more frequent than previously thought. Gender, race, and socioeconomic status are important disease determinants, and there is increasing appreciation of the contribution of family history and environmental exposures in SLE susceptibility. Owing to its systemic nature, assessment of disease activity is challenging, also pertaining to efforts to improve trial endpoints for better discrimination between active drug and placebo. Notably, emerging evidence supports that remission or low disease activity states and prevention of flares are realistic targets in the management of SLE associated with improved prognosis. For the future, we anticipate that high-throughput analyses in patient cohorts will enhance the identification of robust biomarkers for diagnosis, risk stratification, and personalized treatment.

Comparative analysis of the sensitivity and specificity of the classification criteria and correlation with prognosis of disease in patients with Systemic Lupus Erythematosus.

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by significant clinical heterogeneity with early diagnosis being a major challenge, complicated by the absence of formal diagnostic criteria. Instead, classification criteria have been developed to enable the homogenous inclusion of patients in clinical trials, with the most commonly used those of the American College of Rheumatology (ACR 1997) and the Systemic Lupus International Collaborating Clinics Classification Criteria (SLICC 2012). These criteria are widely used in clinical practice as diagnostic tools, although they fail to diagnose up to 20% of patients with SLE or may delay diagnosis. These restrictions have led to the recent (2018) introduction of new classification criteria jointly by the European League Against Rheumatism (EULAR) and ACR. AIMS OF THE STUDY: We will compare the sensitivity and specificity of the earlier and new classification criteria after a systematic analysis (retrospective study) of a group of SLE patients. In addition, we will examine which set of criteria permits the earliest classification of the disease in a prospective cohort of patients with undifferentiated connective tissue disease (UCTD). The prognostic impact (permanent organ damage) of the classification of SLE patients with the three sets of criteria will also be examined. METHODS: Data from the existing Cretan lupus registry will be used to retrospectively include consecutively registered patients aged ≥15 years diagnosed with SLE during 01/2005-12/2016 by an expert physician and followed-up for at least 6 months. All sets of criteria (ACR 1997, SLICC 2012, EULAR/ACR 2018) will be tested at the time of physician-based diagnosis and also at last follow-up. A prospective study arm will include cases with a diagnosis of UCTD and will be followed-up in the outpatient clinic for 3-5 years. ANTICIPATED BENEFITS: This is the first study to include the application of the new criteria (EULAR/ACR 2018) to a group of SLE patients. Determining their diagnostic value in comparison to existing criteria or diagnosis by a specialist will provide important information both for the value of their application at the level of clinical studies and for their use in clinical practice as diagnostic criteria.

Health care and social media: What patients really understand.

Background: Low health literacy is associated with decreased patient compliance and worse outcomes - with clinicians increasingly relying on printed materials to lower such risks. Yet, many of these documents exceed recommended comprehension levels. Furthermore, patients look increasingly to social media (SoMe) to answer healthcare questions. The character limits built into Twitter encourage users to publish small quantities of text, which are more accessible to patients with low health literacy. The present authors hypothesize that SoMe posts are written at lower grade levels than traditional medical sources, improving patient health literacy. Methods: The data sample consisted of the first 100 original tweets from three trending medical hashtags, leading to a total of 300 tweets. The Flesch-Kincaid Readability Formula (FKRF) was used to derive grade level of the tweets. Data was analyzed via descriptive and inferential statistics. Results: The readability scores for the data sample had a mean grade level of 9.45. A notable 47.6% of tweets were above ninth grade reading level. An independent-sample t-test comparing FKRF mean scores of different hashtags found differences between the means of the following: #hearthealth versus #diabetes (t = 3.15, p = 0.002); #hearthealth versus #migraine (t = 0.09, p = 0.9); and #diabetes versus #migraine (t = 3.4, p = 0.001). Conclusions: Tweets from this data sample were written at a mean grade level of 9.45, signifying a level between the ninth and tenth grades. This is higher than desired, yet still better than traditional sources, which have been previously analyzed. Ultimately, those responsible for health care SoMe posts must continue to improve efforts to reach the recommended reading level (between the sixth and eighth grade), so as to ensure optimal comprehension of patients.

Patient and partner dispositional optimism as a long-term predictor of illness representations in autoimmune diseases.

We examined whether the dispositional optimism of patients suffering from an autoimmune disease as well as of their partners can predict, at a dyadic level, their representations of illness consequences, and personal and treatment control, assessed 1 year later. Patient optimism predicted several patient and partner illness representations. Partner optimism was unrelated to own or patient illness representations. Results highlight the strong long-term predictive power of patient optimism and underline the importance of the interpersonal function of personality traits. At the same time, study findings indicate that the dyadic effects of optimism are complex and probably conditional on several factors.

Cognitive deficits early in the course of rheumatoid arthritis.

OBJECTIVE: The aim was to examine the severity and prevalence of cognitive difficulties in persons with rheumatoid arthritis (RA) within the first three years of diagnosis. METHOD: One hundred consecutive RA patients aged 28-67 years (90% women) were administered a battery of 6 neuropsychological tests yielding 14 cognitive indices. Self-reported measures of trait anxiety, depression, impact of disease on daily activities, and pain severity were also obtained along with physician-rated disease severity. RESULTS: Twenty percent of RA patients were classified as cognitively impaired, defined as age- and education-adjusted scores at least 1.5 standard deviations below the population mean on 3 or more cognitive indices. Impaired performance, controlling for age, education, and premorbid cognitive capacity, was detected primarily on measures of short-term memory, immediate and delayed episodic recall, and phonemic fluency. There were modest negative associations between cognitive indices and measures of perceived disease severity (pain level, impact of disease on daily functionality, and overall health quality). CONCLUSIONS: Cognitive deficits on several domains are frequently encountered in relatively young RA patients during the first few years of the disease and may need to be taken into account as important correlates of disease severity and progression.
