RESUMO

OBJECTIVES: To compare the safety of Janus kinase inhibitors (JAKi) with that of tumour necrosis factor inhibitors (TNFi) and determine drug persistence among patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA). METHODS: We analysed data from patients included in BIOBADASER 3.0 and treated with JAKi or TNFi from 2015 to 2023 and estimated the incidence rate ratio (IRR) of adverse events and persistence. RESULTS: A total of 6826 patients were included. Of these, 52% had RA, 25% psoriatic arthritis and 23% axial SpA. Treatment was with TNFi in 86%. The mean duration of treatment was 2.2±2.0 years with TNFi versus 1.8±1.5 with JAKi. JAKis were prescribed in older patients with longer term disease, greater comorbidity and later treatment lines and more frequently as monotherapy. The IRR of all infections and gastrointestinal events was higher among patients with RA treated with JAKi. Drug persistence at 1, 2 and 3 years was 69%, 55% and 45% for TNFi and 68%, 54% and 45% for JAKi. Multivariate regression models showed a lower probability of discontinuation for JAKi (HR=0.85; 95% CI 0.78-0.92) and concomitant conventional synthetic disease-modifying antirheumatic drugs (HR=0.90; 95% CI 0.84-0.96). The risk of discontinuation increased with glucocorticoids, comorbidities, greater disease activity and later treatment lines. CONCLUSIONS: Infections, herpes zoster and gastrointestinal adverse events in patients with RA tended to be more frequent with JAKi. However, prognosis was poor in patients receiving JAKi. Persistence was similar for TNFi and JAKi, although factors associated with discontinuation differed by diagnostic group.

RESUMO

OBJECTIVE: The persistence of biologic (b) and targeted synthetic (ts) disease-modifying antirheumatic drugs(DMARDs) in monotherapy versus in combination with conventional synthetic (cs) DMARDs is still a controversial topic in rheumatic diseases. To clarify this issue, the retention of the initial treatment strategy of b/tsDMARD in combination with csDMARD versus monotherapy in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) patients under real-life conditions was evaluated. Factors associated with maintenance of the initial strategy were analysed. METHODS: Nested cohort study within the Spanish BIOBADASER III registry. Bivariate comparisons and multivariate Cox proportional hazards models were used for the analyses. RESULTS: A total of 2521 patients were included in the study. In the multivariate model, the initial strategy of combination therapy was associated with shorter persistence in patients with RA (hazard ratio [HR] 1.58;95% confidence interval [CI] 1.00-2.50; p = .049), PsA (HR 2.48; 95% CI 1.65-3.72) and AS (HR 16.77; 95% CI 7.37-38.16; p < .001), regardless of sex, time of disease progression, baseline disease activity, glucocorticoid use or type of b/tsDMARD. Overall, the combination strategy was associated with an increased incidence of adverse events (incidence rate ratio [IRR] 1.13; 95% CI 1.05-1.21). CONCLUSIONS: In this real-life study, the strategy of combining a b/tsDMARD with a csDMARD is associated with lower persistence and worse safety profile compared to monotherapy in RA and especially in PsA and AS, suggesting that combination therapy should be rethought as first choice in RA patients, but especially in PsA and AS patients.

RESUMO

OBJECTIVE: To analyze the long-term survival of subcutaneous biosimilar tumor necrosis factor inhibitors compared to the originator molecules in patients with rheumatic diseases, as well as the factors associated with drug discontinuation. METHODS: Retrospective analysis of BIOBADASER, the Spanish multicenter prospective registry of patients with rheumatic disease receiving biologic and targeted disease-modifying antirheumatic drugs. Patients who started etanercept (ETN) or adalimumab (ADA) from January 2016 to October 2023 were included. The survival probabilities of biosimilars and originators were compared using Kaplan-Meier estimating curves. To identify factors associated with differences in the retention rates, hazard ratios (HR) were estimated using Cox regression models for all and specific causes (inefficacy or adverse events [AEs]) of discontinuation. RESULTS: A total of 4162 patients received 4723 treatment courses (2991 courses of ADA and 1732 courses of ETN), of which 722 (15.29%) were with originator molecules and 4001 (84.71%) were with biosimilars. The originators were more frequently discontinued than biosimilars (53.32% vs 33.37%, respectively). The main reason for discontinuation was inefficacy (60.35% of the treatments). The risk of overall discontinuation was lower for biosimilars (adjusted HR 0.84, 95% CI 0.75-0.95). Female sex, obesity, and second or later treatment lines increased the risk of discontinuation, whereas disease duration and the use of concomitant methotrexate were associated with a greater survival. When assessing cause-specific reasons of discontinuation, excluding nonmedical switching, the results from the crude and adjusted analyses showed no significant differences in the retention rate between biosimilars and originators. CONCLUSION: No significant differences were found between treatments in long-term survival due to inefficacy or AEs.

RESUMO

The use of non-invasive liquid biopsy-based cell-free DNA (cfDNA) analysis is an emerging method of cancer detection and intervention. Different analytical methodologies are used to investigate cfDNA characteristics, resulting in costly and long analysis processes needed for combining different data. This study investigates the possibility of using cfDNA data converted for methylation analysis for combining the cfDNA fragment size with copy number variation (CNV) in the context of early colorectal cancer detection. Specifically, we focused on comparing enzymatically and bisulfite-converted data for evaluating cfDNA fragments belonging to chromosome 18. Chromosome 18 is often reported to be deleted in colorectal cancer. We used counts of short and medium cfDNA fragments of chromosome 18 and trained a linear model (LDA) on a set of 2959 regions to predict early-stage (I-IIA) colorectal cancer on an independent test set. In total, 87.5% sensitivity and 92% specificity were obtained on the enzymatically converted libraries. Repeating the same workflow on bisulfite-converted data yielded lower accuracy results with 58.3% sensitivity, implying that enzymatic conversion preserves the cancer fragmentation footprint in whole genome data better than bisulfite conversion. These results could serve as a promising new avenue for the early detection of colorectal cancer using fragmentation and methylation approaches on the same datasets.

RESUMO

PURPOSE: Our aim was to assess oncologic, safety, and quality of life-related outcomes of focal therapy with irreversible electroporation in men with localized prostate cancer. MATERIALS AND METHODS: This was a single-center, phase II study. INCLUSION CRITERIA: prostate cancer International Society of Urological Pathology grade 1-2, prostate specific antigen ≤15 ng/ml, ≤cT2b. Patients were selected based on multiparametric magnetic resonance imaging and transperineal systematic and targeted magnetic resonance imaging-ultrasound fusion-guided biopsy. Ablation of index lesions with safety margin was performed. Primary end point was cancer control, defined as the absence of any biopsy-proven tumor. A control transperineal biopsy was planned at 12 months and when suspected based on prostate specific antigen and/or multiparametric magnetic resonance imaging information. Quality of life was assessed using Expanded Prostate Cancer Index Composite Urinary Continence domain, International Index of Erectile Function, and International Prostate Symptom Score. RESULTS: From November 2014 to July 2021, 41 consecutive patients were included with a median follow-up of 36 months. Thirty patients (73%) had International Society of Urological Pathology grade 1 tumors, 10 (24%) grade 2, and 1 (2.4%) grade 3. Recurrence was observed in 16 of 41 (39%) of the whole cohort, and 16 of 33 (48.4%) who underwent biopsy. In-field recurrence was detected in 5 (15%) and out-of-field in 11 (33.3%). Ten of 41 (24.6%) including 3 of 5 (60%) with in-field recurrences had significant tumors (Gleason pattern 4-5; more than 1 core or any >5 mm involved). Median recurrence-free survival was 32 months (95% CI 6.7-57.2). Twenty-six patients (63.4%) were free from salvage treatment. All patients preserved urinary continence. Potency was maintained in 91.8%. CONCLUSIONS: Irreversible electroporation can achieve satisfactory 3-year in-field tumor control with excellent quality of life results in selected patients.

RESUMO

PURPOSE: We analyzed the association between salivary melatonin rhythm and prostate cancer (PCa). MATERIALS AND METHODS: A total of 40 PCa cases and 41 controls from the CAPLIFE study were analyzed to determine the salivary melatonin rhythm through 6 saliva samples. Amplitude (maximum melatonin peak) was categorized as low or high using the cutoff point median of the controls. Acrophase (time of maximum melatonin peak) was classified as early or late using the same criteria. In addition, the following data were collected: characteristics related to sleep habits, and clinical and sociodemographic information. Melatonin rhythms were represented for cases and controls and analyzed according to urinary symptoms, tumor aggressiveness and tumor extension. Variations in melatonin levels were estimated using generalized estimating equations on the ln-transformed values. To estimate the association between amplitude, acrophase and PCa, adjusted odds ratio (aOR) and 95% CI were calculated using logistic regression models. RESULTS: The mean age was 67.0 years (SD 7.3) for cases and 67.5 (SD 5.5) for controls. Melatonin levels were always lower in PCa cases than in controls. On average, melatonin levels in cases were -64.0% (95% CI -73.4, -51.4) than controls. PCa cases had lower amplitude, 26.0 pg/ml (SD 27.8) vs 46.3 pg/ml (SD 28.2; p <0.001). A high amplitude was associated with a decreased risk of PCa, aOR=0.31 (95% CI 0.11, 0.86), while a late acrophase could be increased risk of PCa, aOR=2.36 (95% CI 0.88, 6.27). CONCLUSIONS: Patients with PCa always had lower melatonin levels than men without PCa, independent of urinary symptomatology or extension and aggressiveness of the tumor.

RESUMO

The management and screening of prostate cancer (PC) is still the main problem in clinical practice. In this study, we investigated the role of aggressiveness genetic markers for PC stratification. We analyzed 201 plasma samples from PC patients and controls by digital PCR. For selection and validation, 26 formalin-fixed paraffin-embedded tissues, 12 fresh tissues, and 24 plasma samples were characterized by RNA-Seq, immunochemistry, immunofluorescence, Western blot, and extracellular-vesicles analyses. We identified three novel non-invasive biomarkers; all with an increased expression pattern in patients (PCA3: p = 0.002, S100A4: p ≤ 0.0001 and MRC2: p = 0.005). S100A4 presents the most informative AUC (area under the curve) (0.735). Combination of S100A4, MRC2, and PCA3 increases the discriminatory power between patients and controls and between different more and less aggressive stages (AUC = 0.761, p ≤ 0.0001). However, although a sensitivity of 97.47% in PCA3 and a specificity of 90.32% in S100A4 was reached, the detection signal level could be variable in some analyses owing to tumor heterogeneity. This is the first time that the role of S100A4 and MRC2 has been described in PC aggressiveness. Moreover, the combination of S100A4, MRC2, and PCA3 has never been described as a non-invasive biomarker for PC screening and aggressiveness.

RESUMO

OBJECTIVES: To determine cardiovascular (CV) mortality and incidence of the first CV event (CVE) in patients with chronic inflammatory rheumatic diseases (CIRD) after 5 years of follow-up. METHODS: This is an analysis of the CARdiovascular in rheMAatology (CARMA) study after 5 years of follow-up. It includes patients with RA (n = 775), AS (n = 738) and PsA (n = 721), and individuals without CIRD (n = 677) attending outpatient rheumatology clinics from 67 public hospitals in Spain. Descriptive analyses were performed for the CV mortality at 5 years. The Systematic COronary Risk Evaluation (SCORE) function at 5 years was calculated to determine the expected risk of CV mortality. Poisson models were used to estimate the incidence rates of the first CVE. Hazard ratios of the risk factors involved in the development of the first CVE were evaluated using the Weibull proportional hazard model. RESULTS: Overall, 2382 subjects completed the follow-up visit at 5 years. Fifteen patients died due to CVE. CV deaths observed in the CIRD cohort were lower than that predicted by SCORE risk charts. The highest incidence rate of CVE [7.39 cases per 1000 person-years (95% CI 4.63, 11.18)] was found in PsA patients. However, after adjusting for age, sex and CV risk factors, AS was the inflammatory disease more commonly associated with CVE at 5 years [hazard ratio 4.60 (P =0.02)], compared with those without CIRD. CONCLUSIONS: Cardiovascular mortality in patients with CIRD at 5 years of follow-up is lower than estimated. Patients with AS have a higher risk of developing a first CVE after 5 years of follow-up.

RESUMO

OBJECTIVES: We aimed to investigate the association between the different antiphospholipid antibodies (aPL) and both systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) manifestations. METHODS: Patients from the RELESSER registry, a Spanish retrospective, cross-sectional, forty-five hospital registry of adult SLE patients, were included. RESULTS: Out of a total of 3,658 SLE patients, 1372 were aPL positive (555 of them fulfilled criteria for APS). All aPL types showed a negative association with cutaneous SLE manifestations. Lupus anticoagulant (LA) and anticardiolipin antibodies (aCL) were both associated with haematological, ophthalmological and neuropsychiatric manifestations. IgG isotypes were associated with a higher risk of lupus manifestations compared with IgM. We found that the risk of neuropsychiatric and ophthalmological manifestations significantly increased with a higher number of positive aPL whereas the risk of cutaneous symptoms showed a negative correlation. All types of aPL, and more strongly LA, were associated with non-criteria antiphospholipid syndrome (APS) manifestations such as thrombocytopenia and haemolytic anaemia. Moreover, LA and aCL (particularly IgG isotype) were also associated with Libman-Sacks endocarditis and cognitive impairment. This association was stronger with more than one positive aPL. All types of aPL were also associated with classic APS manifestations, although LA, IgG isotypes, and patients with more than one aPL displayed a higher risk. CONCLUSIONS: There is a hierarchy for aPL and the risk of APS and SLE manifestations. aCL, and especially LA, confer a higher risk for major organ involvement in SLE. IgG isotypes seem to have a more important role. The load of aPL confer a higher risk for APS and certain SLE manifestations.

RESUMO

AIMS: To identify the definition for urinary continence (UC) after radical prostatectomy (RP) which reflects best patients' perception of quality of life (QoL). METHODS: Continence was prospectively assessed in 634 patients, 12 months after RP using the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) and the number of pads employed in a 24-hour period (pad usage). We used the one-way ANOVA technique with posthoc pairwise comparisons according to Scheffé's method (homogeneous subsets) for assessing the degree of QoL deficit related to urinary incontinence (UI). RESULTS: The continence prevalence is 64.4%, 74.1%, 88.3%, and 35.8% using "0 pads," "1 safety pad," "1 pad," and "ICIQ score 0" definitions, respectively. Pad usage is moderately strongly associated with ICIQ 1, 2, and 3 (ρ = 0.744, 0.677, and 0.711, respectively; p < 0.001). Concordance between classical UC definitions is acceptable between "0 pads-ICIQ score 0" (K = 0.466), but poor for "1 safety pad" and "1 pad" (K = 0.326 and 0.137, respectively). Patients with "0 pad usage" have better QoL related to urine leakage than patients with "1 safety pad" or "1 pad" (1.41 vs. 2.44 and 3.11, respectively; p < 0.05). There were no significant differences found regarding QoL between patients with ICIQ score 0 and ICIQ score 2 (1.01 vs. 1.63; p = 0.63). CONCLUSIONS: Pad usage and the ICIQ-SF's answers provide useful information. We propose a combined definition (0 pads and ICIQ score ≤2) as it is the definition with the least impact on daily QoL.

RESUMO

INTRODUCTION: Antiphospholipid antibodies (aPL) have been associated with organ damage and certain features in systemic lupus erythematosus(SLE) patients. Our aim was to investigate the differences between SLE patients according to the presence of aPL and/or clinical antiphospholipid syndrome (APS). MATERIALS AND METHODS: Patients from the RELESSER-T registry were included. RELESSER-T is a Spanish multicenter, hospital-based, retrospective, SLE registry. RESULTS: We included 2398 SLE patients, 1372 of whom were positive for aPL. Overall 1026 patients were classified as SLE, 555 as SLE-APS and817 as SLE-aPL. Regarding cardiovascular risk factors, SLE-APS patients had higher rates of hypertension, dyslipidemia and diabetes than those with SLE-aPL and SLE (p < 0.001). SLE-APS patients showed higher rates of neuropsychiatric, cardiac, pulmonary, renal and ophthalmological manifestations than the other groups (p < 0.001). SLE-APS patients presented greater damage accrual with higher SLICC values (1.9 ± 2.2 in SLE-APS, 0.9 ± 1.4 in SLE-aPL and 1.1 ± 1.6 in SLE, p < 0.001) and more severe disease as defined by the Katz index (3 ± 1.8 in SLE-APS, 2.7 ± 1.7 in SLE-aPL and 2.6 ± 1.6 in SLE, p < 0.001). SLE-APS patients showed higher mortality rates (p < 0.001). CONCLUSIONS: SLE-APS patients exhibited more severe clinical profiles with higher frequencies of major organ involvement, greater damage accrual and higher mortality than SLE-aPL and SLE patients.

RESUMO

Ureaplasma parvum is the most prevalent genital mycoplasma in women of childbearing age. There is debate around the relevance of its presence in male or female genitals for disease development and as a cofactor. The objective of this study was to determine the prevalence of colonization/infection by U. parvum and its possible relationship with reproductive tract infections. We retrospectively analyzed the presence of U. parvum in patients referred by specialist clinicians for suspicion of genitourinary tract infection. U. parvum was detected in 23.8% of samples, significantly more frequently in females (39.9%) than in males (6%). Among the males, U. parvum was found alone in 68.4% of episodes, with Ct < 30. Among the females, U. parvum was detected in 88.6% of cases, with Ct < 30, including 22 cases with premature rupture of membranes and 6 cases with threat of preterm labor. Co-infection was significantly more frequent in females (62.6%) than in males (31.6%). Given the high prevalence of U. parvum as sole isolate in males and females with genitourinary symptoms, it should be considered in the diagnosis and treatment of genital infections, although its pathogenic role in some diseases has not been fully elucidated.

RESUMO

OBJECTIVES: To assess the plasma apolipoprotein B/apolipoprotein A1 ratio and its potential association with cardiovascular events (CVE) in patients with rheumatoid arthritis (RA). METHODS: A baseline analysis was made of the CARdiovascular in rheuMAtology Project (CARMA), a 10-year prospective study evaluating the presence of at least one CVE in 775 Spanish patients with RA. Of them, 29 had already experienced CVE prior to the inclusion in the study. We assessed the association between the elevation of the apoB/apoA1 ratio with the presence of CVE according to a logistic regression model for possible confounding factors. We also analysed the main parameters of activity of RA and parameters related to lipid metabolism. RA patients were classified according to treatment: patients treated with disease-modifying anti-rheumatic drugs without biologics and those undergoing biologic therapy (anti-TNF-α, anti-IL-6 receptor, and other biologic agents). RESULTS: The apoB/apoA1 ratio of patients who had experienced CVE was higher than that of patients without previous CVE (0.65 vs. 0.60). However, the difference between both subgroups did not reach statistical significance (p=0.197). It was also the case after the multivariate analysis [OR: 1.48 (95% CI: 0.15-14.4); p=0.735]. RA patients from the group with CVE were more commonly receiving lipid-lowering treatment with statins than those without CVE history (41.4% vs. 20%, p=0.005). High HAQ and high atherogenic index were significantly associated with the presence of CVE. There was no statistical association between the type of biologic therapy used in RA and the presence of CVE. CONCLUSIONS: No association between ApoB/apoA1 ratio and CVE was found at the baseline visit of patients with RA from the CARMA study.

RESUMO

OBJECTIVES: Cardiovascular (CV) disease is one of the main causes of morbi-mortality in spondyloarthritis (SpA), partially explained by traditional CV risk factors. Information on lipoprotein(a) [Lp(a)], a non-conventional risk factor, in SpA is scarce. In this study we assessed the prevalence of hyperlipoproteinaemia(a) in SpA patients and analysed the possible related factors. METHODS: A baseline analysis was made of ankylosing spondylitis (AS) and psoriatic arthritis (PsA) patients and controls included in the CARMA project (CARdiovascular in RheuMAtology), a 10-year prospective study evaluating the risk of CV events in chronic inflammatory rheumatic diseases. A multivariate logistic regression model was performed using hyperlipoproteinaemia(a) (Lp(a) >50 mg/dl) as a dependent variable and adjusting for confounding factors. RESULTS: 19.2% (95% CI: 16.80-22.05) of the SpA patients [20.7% (95% CI: 16.91-24.82) of those with AS and 17.7% (95% CI: 14.15-21.75) of those with PsA] and 16.7% (95% CI: 13.23-20.86) of the controls had hyperlipoproteinaemia(a) (p=0.326). Adjusting for age and sex, SpA patients were more likely to have hyperlipoproteinaemia(a) than controls (OR: 1.43, 95%CI: 1.00-2.04; p=0.05), especially those with AS (OR: 1.81, 95%CI: 1.18-2.77; p=0.007). In the adjusted model, apolipoprotein B in all patients, non-steroidal anti-inflammatory drugs in AS, and female sex in PsA, were associated with hyperlipoproteinaemia(a). No disease-specific factors associated with hyperlipoproteinaemia(a) were identified. CONCLUSIONS: SpA patients show a moderately increased risk of hyperlipoproteinaemia(a) compared to controls, especially those with AS. Lp(a) determination may be of interest to improve the CV risk assessment in SpA patients.

RESUMO

OBJECTIVES: To determine the incidence and risk factors of first cardiovascular event (CVE) in patients with chronic inflammatory rheumatic diseases (CIRD). METHODS: Analysis of data after 2.5 years of follow-up from the prospective study CARMA project, that includes patients with CIRD [rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA)] and matched individuals without CIRD from 67 hospitals in Spain. CVE cumulative incidence per 1000 patients was calculated after 2.5 years from the start of the project. Weibull proportional hazard model was used to calculate hazard ratio (HR) and 95% confidence interval (95% CI) of the risk factors. RESULTS: 2595 (89.1%) patients completed the 2.5 years of follow-up visit. Cumulative incidence of CVE in patients with CIRD was 15.30 cases per 1000 patients (95% CI: 12.93-17.67), being higher in the subgroup with AS; 22.03 (95% CI: 11.01-33.04). Patients with AS (HR: 4.11; 95% CI: 1.07-15.79), those with older age (HR: 1.09; 95% CI: 1.05-1.13), systolic hypertension (HR: 1.02; 95% CI: 1.00-1.04) and long duration of the disease (HR: 1.07; 95% CI: 1.03-1.12) were at higher risk of first CVE during the 2.5 years of follow-up. In contrast, female gender was a protective factor (HR: 0.43; 95% CI: 0.18-1.00). CONCLUSIONS: Among CIRD patients prospectively followed-up at rheumatology outpatient clinics, those with AS show higher risk of first CVE. Besides cardiovascular risk factors, such as hypertension, being a man and older as well as having a long disease duration increase the risk of CVE in patients with CIRD.

RESUMO

The retention rate of a biological drug (percentage of patients remaining on treatment over time) provides an index of a drug's overall effectiveness. The golimumab retention rate as first-line biological therapy was high in clinical trial extensions lasting 5 years. Real-world studies also indicate good retention rates but have been of shorter duration. The probability of retention with golimumab treatment was assessed, as any line of anti-tumor necrosis factor-alpha therapy, for up to 5 years in patients with rheumatoid arthritis (RA), axial spondyloarthritis (SpA) or psoriatic arthritis (PsA), associated factors were analyzed. A retrospective database analysis of the Spanish registry of patients with rheumatic disorders receiving biological drugs (BIOBADASER) was performed. Among 353 patients, 29.8% had RA, 41.6% SpA and 28.6% PsA. Golimumab was the first biological drug in 40.1% of patients, second in 30.1% and third/later in 29.8%. The overall probability of retention of golimumab at years 1, 2, 3, 4 and 5 was 85.9% (95% confidence interval 81.4-89.5%), 73.7% (67.1-79.1%), 68.5% (60.5-75.1%), 60.6% (50.2-69.5%) and 57.1% (44.9-67.5%), respectively. Retention was similar across indications (p = 0.070) but was greater when golimumab was used as the first biological agent compared with later therapy lines (p < 0.001). Factors associated with higher retention of golimumab treatment (Cox regression) were use as a first-line biological and concomitant methotrexate treatment; corticosteroid need was associated with lower retention. The long-term probability of golimumab retention was high in this real-world study of patients with rheumatic diseases, especially when used as the first biological drug.

RESUMO

To describe variability in the prescription of biologics (B-DMARDs) for patients with rheumatoid arthritis (RA) in hospitals in Spain, and to explore which characteristics of the patient, the doctor and the hospital are associated with this variability. Cross-sectional multicentric study in 46 rheumatology services of the National Health System. Medical records of 1188 randomly selected patients were reviewed. The association of each variable with B-DMARD prescription was analyzed using simple logistic regressions. Multilevel logistic regression models were created to analyze variability among centers. 36.8% of patients had received B-DMARD. The proportion of patients being treated with B-DMARDs varied between 3.6 and 71.4% depending on the center. Association of prescription of B-DMARD with patient age (OR = 0.958, 95% CI = 0.947-0.968, p < 0.001), longer disease duration (OR = 1.05, 95% CI = 1.032-1.069, p < 0.001), higher CRP levels (OR = 1.022, 95% CI = 1.003-1.042, p = 0.023), and higher number of hospitalizations (OR = 1.286, 95% CI = 1.145-1.446, p < 0.001) was observed. With regard to the center characteristics, the existence of telephone consultations (OR = 1.438, 95% CI = 1.037-1.994, p = 0.03) and the number of beds (OR = 1.045, 95% CI = 1.001-1.091, p = 0.044) were positively associated with prescription of B-DMARDs. Patient variables explained 34.04% of the variability among centers. By adjusting for patient and hospital characteristics, it went up to 83.71%. There is variability in the prescription of B-DMARDs for patients with RA among hospitals which is associated, to a greater extent, with the center characteristics. B-DMARDs prescription could be partly explained by other factors not covered by the current study including the provider's attitudes towards biologics and other hospital characteristics.

RESUMO

BACKGROUND: Gait training for individuals with neurological disorders is challenging in providing the suitable assistance and more adaptive behaviour towards user needs. The user specific adaptation can be defined based on the user interaction with the orthosis and by monitoring the user intentions. In this paper, an adaptive control model, commanded by the user intention, is evaluated using a lower limb exoskeleton with incomplete spinal cord injury individuals (SCI). METHODS: A user intention based adaptive control model has been developed and evaluated with 4 incomplete SCI individuals across 3 sessions of training per individual. The adaptive control model modifies the joint impedance properties of the exoskeleton as a function of the human-orthosis interaction torques and the joint trajectory evolution along the gait sequence, in real time. The volitional input of the user is identified by monitoring the neural signals, pertaining to the user's motor activity. These volitional inputs are used as a trigger to initiate the gait movement, allowing the user to control the initialization of the exoskeleton movement, independently. A Finite-state machine based control model is used in this set-up which helps in combining the volitional orders with the gait adaptation. RESULTS: The exoskeleton demonstrated an adaptive assistance depending on the patients' performance without guiding them to follow an imposed trajectory. The exoskeleton initiated the trajectory based on the user intention command received from the brain machine interface, demonstrating it as a reliable trigger. The exoskeleton maintained the equilibrium by providing suitable assistance throughout the experiments. A progressive change in the maximum flexion of the knee joint was observed at the end of each session which shows improvement in the patient performance. Results of the adaptive impedance were evaluated by comparing with the application of a constant impedance value. Participants reported that the movement of the exoskeleton was flexible and the walking patterns were similar to their own distinct patterns. CONCLUSIONS: This study demonstrates that user specific adaptive control can be applied on a wearable robot based on the human-orthosis interaction torques and modifying the joints' impedance properties. The patients perceived no external or impulsive force and felt comfortable with the assistance provided by the exoskeleton. The main goal of such a user dependent control is to assist the patients' needs and adapt to their characteristics, thus maximizing their engagement in the therapy and avoiding slacking. In addition, the initiation directly controlled by the brain allows synchronizing the user's intention with the afferent stimulus provided by the movement of the exoskeleton, which maximizes the potentiality of the system in neuro-rehabilitative therapies.

RESUMO

PURPOSE: This prospective cohort study assessed the effect of bone quality on the primary and secondary stability of single short implants placed in the posterior region. MATERIALS AND METHODS: A total of 39 short implants (4.1 × 6-mm long) were placed in the posterior region of the maxilla or mandible in 18 patients. Bone quality was classified into type I, II, III, or IV as assessed intrasurgically. Primary implant stability was measured with insertion torque, damping capacity (PTV values), and resonance frequency analysis (ISQ values). Secondary stability was measured by ISQ and PTV at abutment installation. Data were analyzed by using repeated-measures ANOVA and Tukey's test, Kruskall-Wallis test, and Spearman correlation tests. RESULTS: Implants placed in bone type IV had significant lower insertion torque and ISQ values as well as higher PTV values than in bone types I to II (P < 0.05). The mean ISQ values were higher at abutment installation than at implant placement (P < 0.05), regardless the bone type. The assessment methods of implant stability showed a moderate correlation. CONCLUSIONS: Bone quality influences both the primary and secondary stability of single short implants in the posterior region.
