Charting the Etanercept Journey: Tracing Cost Dynamics in Poland's Off-Patent Market from Reference Drug Rivalry to Biosimilar Monopoly.

OBJECTIVES: To evaluate the pricing of etanercept (ETN) reference and biosimilar drugs in a changing competitive to monopolized market. METHODS: We conducted a comprehensive, retrospective analysis of ETN market competition, specifically changes in tender price based on shifts in market monopoly, including the effects on cost evolution, in the off-patent market in Poland. We included a total of 473 tenders for ETN purchase in dedicated biologic drug reimbursement programs, covering both pre-filled syringes and automatic injectors. This study covers the timeframe from November 2017 to December 2023, throughout which we evaluated a unique setting of ETN market re-monopolization from the perspective of payer, hospital and patient benefits resulting from changing cost calculations. RESULTS: Between 2017 and 2022, Erelzi was recorded as having the largest total tender volume (59%), with a mean price [per ETN daily defined dose (DDD)] of €7.28, followed by Enbrel (31%, €8.34) and Benepali (10%, €9.45), respectively. Over the last 6 months of waning market competition, the mean price for winning bids was estimated at €5.69. After market re-monopolization by an ETN biosimilar, the mean price of winning bids increased to €8.09, and continued to increase (€9.71) in the last 6 months of available follow-up. In contrast to the competitive era, no significant relationship between tender volume and winning price was recorded after re-monopolization. In the most recent tenders, mean ETN prices increased up to €15.82, nearly tripling the lowest prices of the competitive market period. In the early re-monopolization market, mean annual treatment cost per patient is estimated at over €3800, which exceeds therapy costs in the prior competitive market years, and is expected to increase to over €6200 based on the most recent tenders. On a healthcare system level, this corresponds to over €3.42 million excess costs due to market monopoly. Higher ETN prices resulted in downstream failure of regulatory incentives to promote affordable biologics. Due to higher pricing, hospitals lost over an estimated €2.52 million, with possible risk of treatment restrictions. For the same reason, the public payer achieved comparable savings, allowing for partial coverage of higher reimbursement expenses. CONCLUSIONS: This nation-level scenario of market re-monopolization by a biosimilar drug confirms net loss and excess costs for the healthcare payer, as can be expected from economic theory. The upwards drug repricing and restriction of treatment availability occurs much more rapidly than the decrement in a period of market competition.

COVID-19 prophylaxis, diagnostics, and treatment in patients with rheumatic diseases. The Polish experts panel opinion.

As severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) evolves, infection management in vulnerable populations requires formalized guidance. Although low-virulence variants of SARS-CoV-2 remain predominant, they pose an increased risk of severe illness in adults with rheumatic and musculoskeletal diseases (RMDs). Several disease-specific (chronic long-grade inflammation, concomitant immunosuppression) and individual (advanced age, multimorbidity, pregnancy, vaccination status) factors contribute to excess risk in RMD populations. Various post-COVID-19 manifestations are also increasingly reported and appear more commonly than in the general population. At a pathogenetic level, complex interplay involving innate and acquired immune dysregulation, viral persistence, and genetic predisposition shapes a unique susceptibility profile. Moreover, incident cases of SARS-CoV-2 infection as a trigger factor for the development of autoimmune conditions have been reported. Vaccination remains a key preventive strategy, and encouraging active education and awareness will be crucial for rheumatologists in the upcoming years. In patients with RMDs, COVID-19 vaccines' benefits outweigh the risks. Derivation of specialized diagnostic and therapeutic protocols within a comprehensive COVID-19 care plan represents an ideal scenario for healthcare system organization. Vigilance for symptoms of infection and rapid diagnosis are key for introducing antiviral treatment in patients with RMDs in a timely manner. This review provides updated guidance on optimal immunization, diagnosis, and antiviral treatment strategies.

Rheumatoid arthritis epidemiology: a nationwide study in Poland.

To assess the incidence and prevalence of rheumatoid arthritis (RA) in Poland for the period 2013-2021, total and dependent on gender, age, region and serological status. Information on reported National Health Fund (NHF) health services and reimbursed prescriptions were used, defining an RA patient as a person who had at least two visits in different quarters with ICD-10 code M05 or M06 and at the same time filled at least one reimbursed prescription for a drug whose active substance is methotrexate, sulfasalazine, leflunomide or was treated with biologic disease-modifying anti-rheumatic drugs (bDMRDs) or targeted synthetic DMARDs (tsDMARDs) as part of a drug program financed by the National Health Fund. The nationwide standardised incidence rate of RA in 2021 was 29 persons per 100,000 population (18 per 100,000 population of seropositive vs. 11 per 100,000 population of seronegative RA). The prevalence of RA in Poland in 2021 was 689.0 people per 100,000 population, a total of 0.7% (1.1% in women and 0.3% in men). The incidence of seronegative RA was approximately 38%. The majority of new RA diagnoses were in the sixth and seventh decades of life, irrespective of patients' gender. The results allow RA to be classified as a disease with a significant social impact. A trend of later onset of RA has been observed, which requires special consideration of the needs of patients over 55 years of age.

Access to biologics and Janus kinase inhibitors for treatment of rheumatic diseases in the biosimilars era in Poland: a nation-level study.

INTRODUCTION: By reducing treatment costs, biosimilars provide an opportunity to improve accessibility to highly effective drugs. OBJECTIVES: This study aimed to evaluate access to biologic disease-modifying antirheumatic drugs (bDMARDs) and Janus kinase inhibitors (JAKis) among patients with rheumatic musculoskeletal diseases within a 10 year timeframe in Poland. PATIENTS AND METHODS: We performed a retrospective analysis using a nationwide public payer database. RESULTS: By 2022, 11 102, 6602, and 4400 patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) were treated with bDMARDs or JAKis. Peak drug utilization was observed for adalimumab, followed by etanercept and tocilizumab. Within the study timeframe, the estimated access to innovative drugs increased from 0.8%, 1.4%, and 0.8% to 3.2%, 8.7%, and 3.5% for RA, PsA, and axSpA patients, respectively. Affordable tumor necrosis factor inhibitors (TNFis) still predominate among innovative therapeutics, but their market share declined from 87% to 46%. The number of patients treated with other bDMARDs/JAKis almost doubled within the prespecified timeframe. Overall, the average annual treatment cost per patient decreased by 60%, from 7315 EUR to 2886 EUR. Despite recent safety warnings, JAKis appear to be increasingly utilized. Additional analyses regarding the COVID­19 pandemic showed impaired access to intravenous therapies, but not subcutaneous or oral formulations. CONCLUSIONS: In Poland, biosimilars­related savings improved availability of higher­priced innovative drugs rather than less costly TNFis. Data­driven resource allocation and dedicated policy solutions facilitating access to affordable biologics are recommended.

Budget impact analysis and treatment availability with biosimilar TNF inhibitors in rheumatic diseases in Poland: real-world evidence using a nationwide database.

OBJECTIVES: Although several years have passed since biologic disease modifying antirheumatic drugs were introduced to the market, considerable disparities in access still remain. Tumour necrosis factor inhibitors (TNFi) have proven to be highly effective and safe for treating patients with rheumatic musculoskeletal diseases (RMDs). The emergence of biosimilars is promising for cost reduction and more equitable, widespread access. METHODS: A retrospective budget impact analysis based on final drug prices was conducted using 12 687 treatment courses for infliximab, etanercept and adalimumab. Estimated and real-life savings for public payer were calculated from an 8-year perspective of TNFi use. Data on the treatment cost and on the evolution in the number of patients treated was provided. RESULTS: From a public payer perspective, the estimated total savings amount to over €243 million for TNFi, with over €166 million attributed to treatment cost reduction in RMDs. Real-life savings were calculated as €133 million and €107 million, respectively. The rheumatology sector generated between 68% and 92% of total savings across models, depending on the adopted scenario. The overall decrease in mean annual cost of treatment ranged between 75% and 89% in the study frame. If all budget savings were spent on reimbursement of additional TNFi, a hypothetical total of almost 45 000 patients with RMDs could be treated in 2021. CONCLUSIONS: This is the first nation-level analysis that shows estimated and real-life direct cost-savings for TNFi biosimilars. Transparent criteria for reinvesting savings should be developed on both a local and an international levels.

Multicenter evaluation of tofacitinib retention and safety in rheumatoid arthritis - why cardiovascular risk factors do not equate to overt risk.

Introduction: This multicenter, real-world, retrospective cohort study aimed to assess the effectiveness and safety of tofacitinib (TOFA) in rheumatoid arthritis (RA). Material and methods: Two hundred nine patients with active RA treated with TOFA, unresponsive to at least 2 conventional synthetic disease-modifying drugs, were recruited. Clinical characteristics were extracted from an electronic registry and supplemented with manual chart review and data linkage with ambulatory care. Drug retention and reasons for discontinuation were evaluated. Results: Median (interquartile range) follow-up in the whole sample was 16.9 (5.93-31.7) months. Mean (standard deviation) age was 51.44 (±11.84) years, with female predominance (n = 168, 80.4%). Only 30 patients (14.4%) had no pre-existing traditional cardiovascular (CV) risk factor at TOFA initiation. Tofacitinib retention rates were high, with median survival estimated at 89.3% at 6 months, 82.4% at 12 months, and 60.4% at 24 months. Ineffectiveness was the primary cause of discontinuation (n = 50). The rate of adverse events (AEs) was relatively low, with lipid abnormalities, blood count alterations, and infectious events among the most common. No major adverse CV event was reported. The incidence rate of AEs necessitating treatment switch was 60.34 (95% CI: 37-92) per 1,000 person-years of follow-up. Presence of multiple (> 3) CV risk factors was associated with lower odds of TOFA retention and treatment effectiveness. Conclusions: Tofacitinib demonstrated high retention rates and a favorable safety profile in RA patients, including those with traditional CV risk factors. Tofacitinib may be a valuable treatment option for RA patients when combined with individualized CV risk management. Further studies are warranted to explore the long-term effects of TOFA and its CV impact in larger populations.

Newly developed cardiovascular risk factors in rheumatoid arthritis patients initiating biologic treatment.

Introduction: Rheumatoid arthritis (RA) is a risk factor (RF) for cardiovascular (CV) disease, a leading cause of mortality in RA patients. Material and methods: Consecutive records of RA patients with high disease activity screened upon biologic therapy initiation were reviewed between January 2001 and 2018. Patients with at least 6-month follow-up and baseline disease activity scores were enrolled (n = 353) and stratified into manifest CV disorder ("overt CVD"), any traditional CV risk factor ("atCVrisk") and no CV risk factor ("vlCVrisk") groups. Results: Overall, mean (SD) patient age was 51.4 (±12.2) years, and 291 (82.4%) subjects were female. Median follow-up was 41.9 (IQR 18.6, 80) months. Overall, 89 (25.2%) individuals developed at least one new CV RF, of which 65 (18.4%) acquired one and 24 (6.8%) two or more. Incident lipid disorders (42, 11.9%), followed by hypertension (14, 4%), atrial fibrillation (17, 4.8%) and venous thromboembolism (VTE) (16, 4.5%), were common. Incident major adverse cardiac events (MACE) were not reported in the vlCVrisk group, in contrast to atCVrisk (n = 8, 4.2%) or overt CVD (n = 4, 18.2%). Age was a significant predictor of incident CV risk factor (HR 1.04, 95% CI: 1.02-1.07; p < 0.01). In age-adjusted analyses, only baseline body mass index (BMI) (HR 1.11, 95% CI: 1.04-1.18; p < 0.01), but not ever smoking (p = 0.93), male sex (p = 0.26), positive RF (p = 0.24), positive ACPA (p = 0.90), or baseline disease activity (p = 0.19), were independent predictor of incident CV risk factors. Conclusions: Patients with RA initiating biologics should be screened for cardiometabolic risk factors, especially at an older age. The presence of at least one risk factor may be linked to a worse long-term prognosis.

Drug Retention and Safety of Secukinumab in a Real-World Cohort of Ankylosing Spondylitis and Psoriatic Arthritis Patients.

Real-life data that support effectiveness of secukinumab (SEC), an interleukin 17A inhibitor, in Poland are few. We aimed to evaluate SEC effectiveness based on drug retention and safety measures reported in electronic medical records (EMRs) of patients with psoriatic arthritis (PsA) and ankylosing spondylitis (AS) from two tertiary-care centers in the region of Lesser Poland. A total one-hundred eighty seven (127 PsA and 60 AS) first (n = 112), second (n = 59) and third-line SEC users were enrolled. The mean (SD) age of the sample was 45.7 (12.9), and 48% were male. All patients were classified with active and severe disease prior to initiation. Administrative delays for SEC users last a median 2 weeks. Median delay from symptom onset to diagnosis was 4 years (IQR 8), and differed by predominant disease subtype. The inefficacy rate was 10.7% and 18.6% for first and second-line users with median (IQR) drug maintenance estimated at 1.22 years (1.46) and 1.51 (1.38), respectively. First-year drug loss defined as drug switch due to inefficacy or adverse event was rare, with median estimates of 0.91 (95% CI; 0.85, 0.97) and 0.86 (95% CI; 0.77, 0.95) for first and second-line, respectively.

Guidelines of the Polish Respiratory Society on the Diagnosis and Treatment of Progressive Fibrosing Interstitial Lung Diseases Other than Idiopathic Pulmonary Fibrosis.

The recommendations were developed as answers to previously formulated questions concerning everyday diagnostic and therapeutic challenges. They were developed based on a review of the current literature using the GRADE methodology. The experts suggest that PF-ILD be diagnosed based on a combination of different criteria, such as the aggravation of symptoms, progression of radiological lesions, and worsening of lung function test parameters. The experts recommend a precise diagnosis of an underlying disease, with serological testing for an autoimmune disease always being included. The final diagnosis should be worked out by a multidisciplinary team (MDT). Patients with an interstitial lung disease other than IPF who do not meet the criteria for the progressive fibrosis phenotype should be monitored for progression, and those with systemic autoimmune diseases should be regularly monitored for signs of interstitial lung disease. In managing patients with interstitial lung disease associated with autoimmune diseases, an opinion of an MDT should be considered. Nintedanib rather than pirfenidon should be introduced in the event of the ineffectiveness of the therapy recommended for the treatment of the underlying disease, but in some instances, it is possible to start antifibrotic treatment without earlier immunomodulatory therapy. It is also admissible to use immunomodulatory and antifibrotic drugs simultaneously. No recommendations were made for or against termination of anti-fibrotic therapy in the case of noted progression during treatment of a PF-ILD other than IPF. The experts recommend that the same principles of non-pharmacological and palliative treatment and eligibility for lung transplantation should be applied to patients with an interstitial lung disease other than IPF with progressive fibrosis as in patients with IPF.

Deep dive into achieving the therapeutic target: results from a prospective, 6­month, observational study nested in routine rheumatoid arthritis care.

INTRODUCTION: Achieving remission or lowdisease activity (LDA) is an integral principle of treat­to­target (T2T) strategy in rheumatoid arthritis (RA). Prior studies have reported that achieving T2T therapeutic goals may be realistic only for a fraction of patients. Prospective, real­world data on achieving target disease control in ambulatory care populations are limited for Central and Eastern European countries. OBJECTIVES: The aim of the study was to analyze the efficacy of treatment and determine simple predictors of achieving T2T therapy goals in daily RA practice. PATIENTS AND METHODS: This multicenter, 6­month study evaluated therapy outcomes and clinical characteristics of 791 consecutive RA outpatients, meeting the preset criteria of inadequate disease control. RESULTS: Only 9% of RA patients achieved remission or LAD after 3 months and 35% after 6 months. Achieving treatment targets after 6 months was associated with lower rates of pain, disability, presenteeism and absenteeism, which reflected improved quality of life. Provider views on adherence appeared discordant with patient claims, and did not predict target achievement. Never smoking, lower body mass index, and lower prednisone dose (<7.5 mg daily) were independently associated with a higher likelihood of achieving T2T therapeutic goals after 6 months. CONCLUSIONS: A combination of clinical characteristics and provider treatment decisions shapes the "profile" of a patient failing to achieve T2T goals. Low­dose steroid equivalent, never smoking, and lower body mass index appear as individual characteristics independently associated with achieving LDA / remission at 3 and 6 months.

Exploring the Diverse Immune and Genetic Landscape of Psoriatic Arthritis.

Psoriatic arthritis (PsA) is characterized by delays in diagnosis and modest effect of treatment in terms of joint response. An understanding of molecular pathomechanisms may aid in developing diagnostic and prognostic models. Genetic susceptibility (e.g., HLA class I genes, IL-23-related genes) can be responsible for the pattern of psoriatic manifestations and affinity for tissue involvement. Gene expression analysis indicates an inflammatory profile that is distinct for PsA, but disparate across tissues. This has clinical implications, as for example, dual blockade of IL-17A and IL-17F can lead to superior clinical effects if there is differential expression of IL-17 receptors in tissues. Structural and functional impairment of barrier tissue, including host-microbiome interactions, may be the source of immune activation. Interplay between different cell populations of innate and adaptive immunity is emerging, potentially providing a link between the transition of skin-to-joint disease. Th17 subsets, IL-17A, IL-17F and IL-23 are crucial in PsA pathogenesis, with both clinical and experimental evidence suggesting a differential molecular landscape in cutaneous and articular compartments.

Real-World Data from a Multi-Center Study: Insights to Psoriatic Arthritis Care.

INTRODUCTION: Real-world data indicate disparities in biologic access across Europe. OBJECTIVES: To describe the national structure of PsA care in Poland, with a particular focus on the population of inadequate responders (IRs) and difficulties associated with biologic therapy access. METHODS: A pool of rheumatologic and dermatologic care centers was created based on National Health Fund contract lists (n = 841), from which 29 rheumatologic and 10 dermatologic centers were sampled randomly and successfully met the inclusion criterium. Additionally, 33 tertiary care centers were recruited. For successful center recruitment, one provider had to recruit at least one patient that met the criteria for one of the four pre-defined clinical subgroups, in which all patients had to have active PsA and IR status to at least 2 conventional synthetic disease-modifying drugs (csDMARDs). Self-assessment questionnaires were distributed among physicians and their patients. RESULTS: Barriers to biologic DMARD (bDMARD) treatment are complex and include stringency of reimbursement criteria, health care system, logistic/organizational, and personal choice factors. For patients who are currently bDMARD users, the median waiting time from the visit, at which the reimbursement procedure was initiated, to the first day of bDMARD admission was 9 weeks (range 2-212; 32% < 4 weeks, 29% 5-12 weeks, 26% 13-28 weeks, 13% with >28 weeks delay). Out of all inadequate responder groups, bDMARD users are the only group with "good" therapeutic situation and satisfaction with therapy. Patient satisfaction with therapy is not always concordant with physician assessment of therapeutic status. CONCLUSIONS: Despite the fact that over a decade has passed since the introduction of biologic agents, in medium welfare countries such as Poland, considerable healthcare system barriers to biologic access are present. Out of different IR populations, patient satisfaction with treatment is often discordant with physician assessment of disease status.

Management of rheumatoid arthritis in Poland - where daily practice might not always meet evidence-based guidelines.

INTRODUCTION: International recommendations are intended to help rheumatologists in the effective management of rheumatoid arthritis (RA) through an evidence-based approach. This research aimed to evaluate management patterns and associated difficulties encountered by rheumatologists in daily practice. MATERIAL AND METHODS: Interviewers recruited 101 Polish rheumatologists in a random quota-based, nationwide sample of outpatient clinics. Quantitative data were input online using a computer-assisted web interview tool. RESULTS: Disease-modifying antirheumatic drugs (DMARDs) are not initiated at the time of diagnosis in 15% of RA patients, most often due to difficulties in patient-provider communication. The RA activity is assessed every 4 to 6 months by 30% of rheumatologists, and 64% of patients are reported to never achieve remission. Composite indices are the most reliable indicators of remission only for 38% of responders. Despite inadequate disease control with ≥ 2 treatment schedules with synthetic DMARDs, 34% of these patients are not considered for biological DMARDs (bDMARDs). Contraindications and reimbursement barriers are the most frequently stated reasons. Therapy with glucocorticoid (GC) lasting over 3 months is reported by 70% of rheumatologists. International recommendations are stated as the most common basis for treatment decisions. CONCLUSIONS: Awareness of recommendations is not sufficient to ensure their application in clinical practice. Inadequate management of RA is quite prevalent, with a substantial contribution of non-medical factors. Daily practice mainly deviates from guidelines regarding frequency and mode of monitoring measures, time to DMARD initiation, and duration of GC treatment. Education programs and policy changes may significantly narrow the gap between evidence and practice.

An expert opinion of the Polish Cardiac Society Working Group on Pulmonary Circulation and the Polish Society for Rheumatology on the diagnosis and treatment of pulmonary hypertension in patients with connective tissue disease.

Systemic connective tissue diseases (CTDs) comprise a large group of diseases that are auto-immune in nature and characterized by the involvement of multiple systems and organs. Pul-monary hypertension (PH) of various etiologies may develop in the course of CTD, including pulmonary arterial hypertension (PAH), PH secondary to the lung disease, postcapillary PH in the course of left heart disease, and chronic thromboembolic pulmonary hypertension (CTEPH). In addition, the different forms of PH may coexist with each other. Among patients with CTD, PAH occurs most commonly in those with systemic sclerosis, where it affects ap-proximately 8%-12% of patients. The prognosis in patients with untreated PAH is very poor. It is particularly important to identify the high-risk CTD-PAH population and to perform effi-cient and accurate diagnostics so that targeted therapy of the pulmonary arteries can be intro-duced. Echocardiography is used to screen for PH, but clinical and echocardiographic suspicion of PH always requires confirmation by right heart catheterization. Confirmation of PAH ena-bles the initiation of life-prolonging pharmacological treatment in this group of patients, which should be administered in referral centers. Drugs available for pharmacological management include endothelin receptor antagonists, phosphodiesterase-5 inhibitors, and prostacyclins.

Patient-Centered Care in Psoriatic Arthritis-A Perspective on Inflammation, Disease Activity, and Psychosocial Factors.

Psoriatic arthritis (PsA) is a seronegative spondyloarthropathy characterized by skin lesions, dactylitis, and enthesitis. Patients with PsA suffer from a variety of psychosocial difficulties and nonspecific symptoms early on in the disease course and continue to experience progressive disease due to delays in diagnosis and treatment. Symptoms initially viewed as somatization could lead to undertreatment and promote psychological distress, poor coping, and negative patient-provider relationships. Pain and fatigue are important complaints that affect the patient's perception and may need to be addressed with a multidisciplinary approach. Maladaptive cognitive responses can lead to a negative illness perception and impact patient beliefs and concerns over treatment, as well as nonadherence. An underlying inflammatory component in affective disorders has been examined, though whether and how it may interact mechanistically in PsA warrants interest. Cognitive behavioral therapy represents a nonpharmacological treatment modality that can be combined with cytokine-targeted therapy to address both somatic and psychological complaints. Future directions for research include: (1) Elucidating nonspecific manifestations (e.g., subclinical stage, differential with functional syndromes) of PsA and how they impact diagnosis and management; (2) characterizing immune-mediated components of mood disorders in PsA; and (3) whether a bidirectional approach with abrogating inflammation and psychotherapeutic support leads to improved outcomes.

Evaluation of Risk Factors for Falls in Patients with Rheumatoid Arthritis.

BACKGROUND The aim of our study was to investigate the risk factors for falls in the rheumatoid arthritis (RA) patient population in Poland. This would be a major step towards the development of new fall prevention programs. MATERIAL AND METHODS There were 450 RA patients who met the criteria of the American College of Rheumatology who participated in this study. The average age of patient participants was 54.2 years; the average RA duration was 15.1 years. All patients filled out the study questionnaire regarding falls, medications, and diseases, and they filled out the Polish version of the Health Assessment Questionnaire (HAQ). RESULTS Of the 400 patients, 203 patients (51%) experienced falls. Out of the 268 falls experienced by study patients, 113 falls (42%) were due to an environmental cause, the remainder 155 falls were caused by health conditions. The number of falls positively correlated with HAQ scores (r=0.42, P<0.01) and the duration of RA (r=0.39, P<0.05). For individuals who had fallen 3 or more times, there was a stronger positive correlation between the number of falls and the total HAQ score (r=0.61, P<0.01). The main risk factors for falls in the study group were dizziness (odds ratio [OR]=3.42), the use of hypotensive medication (OR=2.82), foot deformities (OR=4.09), and a high HAQ score (OR=2.59). Other factors such as drug use (e.g., glucocorticoids), pain, and duration of RA were measured using a visual analogue scale, and were found not to have increased the risk for falls and fractures (P>0.05). CONCLUSIONS Knowledge about risk factors can help identify high-risk patients to help decrease their risk of falling, thus preventing fall-related injuries.

Conley Index Approach to Sampled Dynamics.

The topological method for the reconstruction of dynamics from time series [K. Mischaikow et al., Phys. Rev. Lett., 82 (1999), pp. 1144-1147] is reshaped to improve its range of applicability, particularly in the presence of sparse data and strong expansion. The improvement is based on a multivalued map representation of the data. However, unlike the previous approach, it is not required that the representation has a continuous selector. Instead of a selector, a recently developed new version of Conley index theory for multivalued maps [B. Batko, SIAM J. Appl. Dyn. Syst., 16 (2017), pp. 1587-1617; B. Batko and M. Mrozek, SIAM J. Appl. Dyn. Syst., 15 (2016), pp. 1143-1162] is used in computations. The existence of a continuous, single valued generator of the relevant dynamics is guaranteed in the vicinity of the graph of the multivalued map constructed from data. Some numerical examples based on time series derived from the iteration of Hénon-type maps are presented.

Physician Adherence to Treat-to-Target and Practice Guidelines in Rheumatoid Arthritis.

Principles of treat-to-target (T2T) have been widely adopted in both multinational and regional guidelines for rheumatoid arthritis (RA). Several questionnaire studies among physicians and real-world data have suggested that an evidence-practice gap exists in RA management. Investigating physician adherence to T2T, which requires a process measure, is difficult. Different practice patterns among physicians are observed, while adherence to protocolized treatment declines over time. Rheumatologist awareness, agreement, and claims of adherence to T2T guidelines are not always consistent with medical records. Comorbidities, a difficult disease course, communication barriers, and individual preferences may hinder an intensive, proactive treatment stance. Interpreting deviations from protocolized treatment/T2T guidelines requires sufficient clinical context, though higher adherence seems to improve clinical outcomes. Nonmedical constraints in routine care may consist of barriers in healthcare structure and socioeconomic factors. Therefore, strategies to improve the institution of T2T should be tailored to local healthcare. Educational interventions to improve T2T adherence among physicians may show a moderate, although beneficial effect. Meanwhile, a proportion of patients with inadequately controlled RA exists, while management decisions may not be in accordance with T2T. Physicians tend to be aware of current guidelines, but their institution in routine practice seems challenging, which warrants attention and further study.

Factors associated with quality of life in systemic sclerosis: a cross-sectional study.

INTRODUCTION: Systemic sclerosis (SSc) is a connective tissue disease characterized by progressive fibrosis of the skin and internal organs, leading to their failure and disturbances in the morphology and function of blood vessels. The disease affects people in different ways, and identifying how the difficulties and limitations are related to quality of life may contribute to designing helpful interventions. The aim of this study was to identify factors associated with quality of life in people with SSc. METHODS: This was a cross-sectional study conducted in 11 rheumatic centres in Poland. Patients diagnosed with SSc were included. Quality of life was measured using the SSc Quality of Life Questionnaire (SScQoL). The following candidate factors were entered in preliminary multivariable analysis: age, place of residence, marital status, occupational status, disease type, disease duration, pain, fatigue, intestinal problems, breathing problems, Raynaud's symptoms, finger ulcerations, disease severity, functional disability, anxiety and depression. Factors that achieved statistical significance at the 10% level were then entered into a final multivariable model. Factors achieving statistical significance at the 5% level in the final model were considered to be associated with quality of life in SSc. RESULTS: In total, 231 participants were included. Mean age (SD) was 55.82 (12.55) years, disease duration 8.39 (8.18) years and 198 (85.7%) were women. Factors associated with quality of life in SSc were functional disability (ß = 2.854, p < 0.001) and anxiety (ß = 0.404, p < 0.001). This model with two factors (functional disability and anxiety) explained 56.7% of the variance in patients with diffuse SSc and 73.2% in those with localized SSc. CONCLUSIONS: Functional disability and anxiety are significantly associated with quality of life in SSc. Interventions aimed at improving either of these factors may contribute towards improving the quality of life of people with SSc.
