Background: Remission/ low disease activity (LDA) are the main treatment goals in rheumatoid arthritis (RA) patients. Two tools showing the ability to predict golimumab treatment outcomes in patients with RA were published., Objectives: To estimate the real-world accuracy of two quantitative tools created to predict RA remission and low disease activity., Methods: Multicenter, observational study, using data from the Rheumatic Diseases Portuguese Register (Reuma.pt), including biologic naïve RA patients who started an anti-TNF as first-line biologic and with at least 6 months of follow-up. The accuracy of two matrices tools was assessed by likelihood-ratios (LR), sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV) and area under the ROC curve (AUC)., Results: 674 RA patients under first-line anti-TNF (266 etanercept, 186 infliximab, 131 adalimumab, 85 golimumab, 6 certolizumab pegol) were included. The median (IQR) age was 53.4 (44.7-61.1) years and the median disease duration was 7.7 (3.7-14.6) years. The majority were female (72%). Most patients were RF and/or ACPA positive (75.5%) and had erosive disease (54.9%); 58.6% had comorbidities. At 6-months, 157 (23.3%) patients achieved remission (DAS28 ESR < 2.6) and 269 (39.9%) LDA (DAS28 ESR ≤ 3.2). Area under the curve for remission in this real-world sample was 0.756 [IC 95% (0.713-0.799)] and for LDA was 0.724 [IC 95% (0.686 -0.763)]. The highest LR (8.23) for remission state was obtained at a cut-off ≥ 67%, with high specificity (SP) (99.6%) but low sensitivity (SN) (3.2%). A better balance of SN and SP (65.6% and 73.9%, respectively) was observed for a cut-off >30%, with a LR of 2.51, PPV of 43.3% and NPV of 87.6%., Conclusion: In this population, the accuracy of the prediction tool was good for remission and LDA. Our results corroborate the idea that these matrix tools could be helpful to select patients for anti-TNF therapy.

Objective: The aim of the present systematic review and meta-analysis is to know, based on the available randomized controlled trials, if the non-surgical and non-pharmacological interventions commonly used for knee osteoarthritis (OA) patients are effective and which are the most effective ones., Material and Methods: RCTs were identified through electronic databases respecting the following terms to guide the search strategy: PICO (Patients - Humans with knee OA; Intervention - Non-surgical and non-pharmacological interventions; Comparison - Pharmacological, surgical, placebo, no intervention, or other non-pharmacological/non-surgical interventions; Outcomes - Pain, physical function and patient global assessment). The methodological quality of the selected publications was evaluated using the PEDro and GRADE scales. Additionally, a meta-analysis was performed using the RevMan. Only studies with similar control group, population characteristics, outcomes, instruments and follow-up, were compared in each analysis., Results: Initially, 52 RCTs emerge however, after methodological analysis, only 39 had sufficient quality to be included. From those, only 5 studies meet the meta-analysis criteria. Exercise (especially resistance training) had the best positive effects on knee OA patients. Pulsed Electromagnetic Fields and Moxibustion showed to be the most promising interventions from the others. Balance Training, Diet, Diathermy, Hydrotherapy, High Level Laser Therapy, Interferential Current, Mudpack, Neuromuscular Electrical Stimulation, Musculoskeletal Manipulations, Shock Wave Therapy, Focal Muscle Vibration, stood out, however more studies are needed to fully recommend their use. Other interventions did not show to be effective or the results obtained were heterogeneous., Conclusions: Exercise is the best intervention for knee OA patients. Pulsed Electromagnetic Fields and Moxibustion showed to be the most promising interventions from the others options available.

Osteopoikilosis (OPK) is a rare, hereditary, usually asymptomatic disease characterized by the presence of multiple, well-defined sclerotic lesions distributed in peri-articular locations, frequently diagnosed as an incidental finding. Differential diagnosis with osteoblastic metastases is fundamental. This article reports six cases of OPK diagnosed in Portuguese Rheumatology Centers.

Eosinophilic granulomatosis with polyangiitis is a rare multisystemic disorder, characterized by necrotizing vasculitis affecting small to medium-sized vessels, associated with asthma and eosinophilia. Cardiac involvement is the most important predictor of mortality and it seems to be more frequent in anti-neutrophil cytoplasmic antibodies-negative patients. Cardiomyopathy and congestive heart failure can occur but a significant proportion of patients are asymptomatic. We present a case of this condition in a 65-year-old woman with a past medical history of rhinosinusitis and recent episodes of asthma, that developed palpable purpura, sensory deficiency and excruciating pain mainly in the lower limbs. A significant hypereosinophilia and elevated troponin level were found, although she had not cardiac symptomatology. Cardiovascular magnetic resonance revealed late gadolinium enhancement and a severe reduction of the left ventricular ejection fraction. Mononeuritis multiplex was documented and diagnosis was confirmed by biopsy. Complementary cardiac investigation is mandatory in any patient with suspicion of Eosinophilic granulomatosis with polyangiitis. Early detection and the appropriate treatment are crucial due to the possible life-threatening manifestations.

Objective - Update the last known umbrella review and summarize the available high-quality evidence from systematic reviews on the effectiveness of non-pharmacological and non-surgical interventions for patients with knee OA. Methods - The systematic reviews were identified thought electronic databases such as, MEDLINE, Embase, Physiotherapy Evidence Database (PEDro), The Cochrane Library, SciELo, Science Direct, Google Scholar, Research Gate and B-ON. The studies selection respected the following terms to guide the search strategy using the P (humans with knee osteoarthritis) I (non-pharmacological and non-surgical treatments) C (pharmacological, surgical, placebo, no intervention, or other non-pharmacological/ non-surgical conservative treatments) O (pain, functional status, stiffness, inflammation, quality of life and patient global assessment) model. Results - Following the PRISMA statement, 41 systematic reviews were found on the electronic databases that could be included in the umbrella review. After methodical analysis (R-AMSTAR), only 35 had sufficient quality to be included. There is gold evidence that Standard Exercise programs can reduce pain and improve physical function in patients with knee OA. Additionally, there is silver evidence for Acupuncture, Aquatic Exercise, Electroacupuncture, Interferential Current, Kinesio Taping, Manual Therapy, Moxibustion, Pulsed Electromagnetic Fields, Tai Chi, Ultrasound, Yoga, and Whole-Body Vibration. For other interventions, the quality of evidence is low or did not show sufficient efficacy from the systematic reviews to support their use. Conclusion - Comparing to last known umbrella review, similar results were achieved on Acupuncture and Exercise interventions to improve the patients' pain, stiffness, function and quality of life, but it was found different results regarding the utilization of Transcutaneous Electrical Nerve Stimulation and Low-Level Laser Therapy as they do not improved the patients' pain and physical function.
