Brazilian Society of Rheumatology 2020 guidelines for psoriatic arthritis.

Psoriatic arthritis (PsA) is a chronic and systemic immune disease characterized by inflammation of peripheral and/or axial joints and entheses in patients with psoriasis (PsO). Extra-articular and extracutaneous manifestations and numerous comorbidities can also be present. These recommendations replace the previous version published in May 2013. A systematic review of the literature retrieved 191 articles that were used to formulate 12 recommendations in response to 12 clinical questions, divided into 4 sections: diagnosis, non-pharmacological treatment, conventional drug therapy and biologic therapy. These guidelines provide evidence-based information on the clinical management for PsA patients. For each recommendation, the level of evidence (highest available), degree of strength (Oxford) and degree of expert agreement (interrater reliability) are reported.

Brazilian recommendations for the use of nonsteroidal anti-inflammatory drugs in patients with axial spondyloarthritis.

Spondyloarthritis (SpA) is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. Over some decades, nonsteroidal anti-inflammatory drugs (NSAIDs) have been the basis for the pharmacological treatment of patients with axial spondyloarthritis (axSpA). However, the emergence of the immunobiologic agents brought up the discussion about the role of NSAIDs in the management of these patients. The objective of this guideline is to provide recommendations for the use of NSAIDs for the treatment of axSpA. A panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis of randomized clinical trials for 15 predefined questions. The Grading of Recommendations, Assessment, Development and Evaluation methodology to assess the quality of evidence and formulate recommendations were used, and at least 70% agreement of the voting panel was needed. Fourteen recommendations for the use of NSAIDs in the treatment of patients with axSpA were elaborated. The purpose of these recommendations is to support clinicians' decision making, without taking out his/her autonomy when prescribing for an individual patient.

Evaluation of the association between osteoporosis and postural balance in postmenopausal women.

The incidence of osteoporosis has been increasing, as have fractures resulting from falls. Postural balance was evaluated in postmenopausal women with and without lumbar osteoporosis. One hundred and twenty-six postmenopausal women aged 55-65 years were evaluated and separated into two groups according to the bone mineral density values of their lumbar spine: the osteoporosis group and the control group, paired by age (P = 0.219) and physical activity (P = 0.611). There was no difference between the groups (P = 0.139) regarding falls reported in the previous 12 months. Functional mobility was evaluated through the Timed Up and Go Test. Postural balance was evaluated using a portable force platform in standard standing position, with eyes open and closed, for 60s. Muscle strength was evaluated through an isokinetic dynamometer. This study shows that there is no difference in knee muscle strength and functional mobility (P = 0.121), postural balance with eyes open [mediolateral displacement (P = 0.286) and mean velocity of the center of pressure (COP) (P = 0.173)] and with eyes closed [mediolateral displacement (P = 0.163), and the mean velocity of displacement of the COP (P = 0.09)] in both groups. Subjects reporting falls had greater mediolateral displacement (P = 0.028) in both groups. Postmenopausal women aged between 55 and 65 years do not present changes in postural balance irrespective of lumbar osteoporosis. Greater COP mediolateral displacement is related to the occurrence of falls in postmenopausal women in the previous year.

Osteopenia and osteoporosis in people living with HIV: multiprofessional approach.

Increasing bone mineralization abnormalities observed among people living with HIV (PLWHIV) result from various factors relating to the host, the virus, and the antiretrovirals used. Today, HIV infection is considered to be a risk factor for bone mineralization disorders. The test most recommended for diagnosing osteoporosis is measurement of bone mineral density by means of dual energy X-ray absorptiometry at two sites. Osteoporosis treatment has the aims of bone mass improvement and fracture control. A combination of calcium and vitamin D supplementation may reduce the risk of fractures. Antiresorptive drugs act by blocking osteoclastic activity and reducing bone remodeling. On the other hand, bone-forming drugs stimulate osteoblastogenesis, thereby stimulating the formation of bone matrix. Mixed-action medications are those that are capable of both stimulating bone formation and inhibiting reabsorption. Antiresorptive drugs form the group of medications with the greatest quantity of scientific evidence confirming their efficacy in osteoporosis treatment. Physical activity is a health promotion strategy for the general population, but only preliminary data on its real value and benefit among PLWHIV are available, especially in relation to osteoporosis.

Comparaçao da gordura corporal de mulheres idosas segundo antropometria, bioimpedância e DEXA / Comparison of body fat using anthropometry, bioelectrical impedance and DEXA in elderly women

Verificar a concordância e comparar o percentual de gordura corporal (GC) através das medidas de dobras cutâneas (DC), bioimpedância (BIA) e DEXA. Foram availadas vinte mulheres voluntárias (62 a79 anos), utilzando-se duas equaçoes distintas para DC (19,20) e BIA (23) e avaliaçao por DEXA. As estimativas do porciento GC foram comparadas através de análise de variância para medidas repetidas (ANOVA-Bonferroni), a correlaçao foi verificada pelo coef. de Pearson e a concordância pelo procedimento de Bland & Altman (25). O por ciento GC obtido pela BIA apresentou baixa correlaçao (r<0,5) quando comparado com as duas equaçoes de DC. Os valores do por ciento GC variaram de 31,5 ñ 5,5 a 41,2 ñ 6,1 (media e desvio padrao) para Jackson (19) e DEXA, respectivamente. A análise de comparaçao múltipla mostrou que nao foram observadas diferenças significativas (p<0,05) entre os métodos e/ou equaçoes de BIA(RJL-CompCorp) vs. DC-Jackson (19). Para todas as outras comparaçoes, as diferenças foram significativas (p<0,001). Na comparaçao entre RJL-CompCorp vs. Deurenberg (23), foi verificada boa concordância, assim como para DEXA vs. Durning e Womersley, (20). Embora os métodos e/ou equaçoes utilizados nesse estudo sejam da ampla utilizaçao para estimar a GC em indivíduos idosos, nenhuma técnica deve ser aceita como método único de referencia nessa populaçao. Cada método apresenta limitaçoes e a comparaçao pode ser util para a interpretaçao dos resultados obtidos
