Depression and anxiety in patients with multiple sclerosis treated with interferon-beta or fingolimod: Role of indoleamine 2,3-dioxygenase and pro-inflammatory cytokines.

Depression/anxiety (D/A) occurs in up to 50% of multiple sclerosis (MS) patients. Proinflammatory cytokines induce classical symptoms of depression. Activation of the inflammatory response also triggers production of indoleamine 2,3-dioxygenase (IDO), which catabolizes tryptophan, the amino acid precursor of serotonin and melatonin.

The impact of physical functions on depressive symptoms in people with multiple sclerosis.

Background: Multiple sclerosis (MS) is an immune-mediated disease that affects the central nervous system. The impact of MS transcends physical functions and extends to psychological impairment. Approximately 50% of people with MS develop depressive symptoms during their lifetime and depressive symptoms may predict impairment of physical functions.

Opportunistic tropical infections in immunosuppressed patients.

Autoimmune and autoinflammatory diseases are associated with severe morbidity, and represent an impactful health and economic burden worldwide. The treatment of these diseases can include a course with detrimental side effects. Immunosuppression increases the risk of opportunistic infections, but in some cases, the abrupt discontinuation of these medications can result in immune reconstitution inflammatory syndrome.

Prospective evaluation of hypromellose 2% for punctal occlusion in patients with dry eye.

Purpose: The aim of this study was to evaluate the effectiveness of punctal occlusion using hypromellose 2% in patients with dry eye.

Methods: In this prospective, randomized single-blinded clinical trial, we evaluated 76 eyes of 38 patients (36 women and 2 men) with dry eye secondary to rheumatic diseases. In each patient, the lower lacrimal punctum of 1 eye was occluded using hypromellose 2%, whereas the contralateral eye underwent a simulation of the procedure (control group).

Occurrence of Autoimmune Diseases Related to the Vaccine against Yellow Fever.

Yellow fever is an infectious disease, endemic in South America and Africa. This is a potentially serious illness, with lethality between 5 and 40% of cases. The most effective preventive vaccine is constituted by the attenuated virus strain 17D, developed in 1937.

Adele Bloch-Bauer (1881-1925): Possible diagnoses for Gustav Klimt's Lady in Gold.

One of the most famous works by the Austrian symbolist painter Gustav Klimt and one of the most widely reproduced works of art worldwide, Adele Bloch-Bauer I which portrays the beautiful wife of Austrian magnate Ferdinand Bloch-Bauer. Adele was the only woman painted by Klimt on more than one occasion. Apart from the beauty and value of the painting, the daring sea of gold that surrounds Adele and the gentle intimacy with which her fragile figure is portrayed have shrouded the history of this painting in mystery.

The physician, the Emperor and the fibromyalgia: Charles-Édouard Brown-Séquard (1817-1894) and Dom Pedro II (1825-1891) of Brazil.

The physician Charles-Édouard Brown-Séquard was a neurologist of considerable importance. In 1846 his thesis 'Researches and Experiments on the Physiology of the Spinal Cord' brought out knowledge about the sensory pathways which remains until today. The Emperor, Dom Pedro II was the second and last Emperor of Brazil, reigning for 49 years and remembered for defending the nation's integrity, the end of slavery, support for education and culture, diplomacy and relations with international personalities.

Exercise and fatigue in rheumatoid arthritis.

Fatigue, the enduring sensation of weakness, lack of energy, tiredness or exhaustion, is described by 40%-80% of patients with rheumatoid arthritis as their most disabling symptom with wide-ranging consequences for quality of life. Little attention has been paid to its multidimensional nature or to its reliability as a measure to evaluate progression of the disease. Low impact aerobic exercise affects the level of fatigue, and this same level of fatigue influences the exercise itself.

Haptoglobin and myeloperoxidase (- G463A) gene polymorphisms in Brazilian sickle cell patients with and without secondary iron overload.

We aimed to investigate the influence of haptoglobin (Hp) and myeloperoxidase (MPO - G463A; dbSNP rs2333227) gene polymorphisms on 78 sickle cell patients of a public hospital in the Federal District/Brazil with and without iron overload, to evaluate a possible association between these polymorphisms and clinical variability, response to treatment and prognosis. Data were obtained through laboratory tests, questionnaires, research in medical records and analyses of polymorphisms using PCR-based methods. Positive correlations were found between Hp and ferritin levels, hydroxyurea treatment, hospitalisation for and sequelae from stroke; and between MPO and number of hospitalizations in the past 12 months and splenectomy.

Low dynamic muscle strength and its associations with fatigue, functional performance, and quality of life in premenopausal patients with systemic lupus erythematosus and low disease activity: a case-control study.

Background: The purpose of the present study was to compare dynamic muscle strength, functional performance, fatigue, and quality of life in premenopausal systemic lupus erythematosus (SLE) patients with low disease activity versus matched-healthy controls and to determine the association of dynamic muscle strength with fatigue, functional performance, and quality of life in SLE patients.

Methods: We evaluated premenopausal (18-45 years) SLE patients with low disease activity (Systemic lupus erythematosus disease activity index [SLEDAI]: mean 1.5 ± 1.

Effectiveness of exercise on cognitive impairment and Alzheimer's disease.

Physical activity has a protective effect on brain function in older people. Here, we briefly reviewed the studies and results related to the effects of exercise on cognitive impairment and Alzheimer's disease. The main findings from the current body of literature indicate positive evidence for structured physical activity (cardiorespiratory and resistance exercise) as a promising non-pharmacological intervention for preventing cognitive decline.

The quality of life of patients with lupus erythematosus influences cardiovascular capacity in 6-minute walk test.

Objective: To assess the association between quality of life and distance walked in the 6-minute walk test (6MWT) in Brazilian premenopausal patients with systemic lupus erythematosus (SLE) and compare their results with those of healthy controls.

Methods: Twenty-five premenopausal (18-45 years) patients diagnosed with low-activity SLE (mean SLEDAI: 1.52 ± 1.

Imaging diagnosis of early rheumatoid arthritis.

Early diagnosis of rheumatoid arthritis is essential for its proper management. Currently, the initial phase of rheumatoid arthritis is known to provide a window of therapeutic opportunity. Although the diagnosis is primarily clinical, the development and improvement of laboratory and imaging methods have contributed to earlier diagnosis and determination of procedures in early rheumatoid arthritis.

Pierre-Auguste Renoir (1841-1919) and rheumatoid arthritis.

Pierre-Auguste Renoir (1841-1919), one of the world's most celebrated impressionist painters, suffered from rheumatoid arthritis for most of his life. His symptoms developed when he was in his 50s and they became aggressive at about the age of 60 years that led to almost complete disability when he was 70 years old. Although the deformities he suffered because of the rheumatoid arthritis were disabling, Renoir never stopped painting nor decreased the quality of his work.

Risk of orthopedic surgical site infections in patients with rheumatoid arthritis treated with antitumor necrosis factor alfa therapy.

Introduction. International guidelines recommend interruption of anti-TNF medications in the perioperative period, but there are no randomized trials to support such recommendation. Objectives.

The interactions between hemostasis and resistance training: a review.

Physical inactivity is considered a risk factor for cardiovascular disease and is strongly associated with changes in arterial structure. Regular physical activity and exercise contributes to the prevention of coronary artery disease. Therefore, cardiovascular and resistance training improve hemostatic parameters and promote a less thrombotic blood profile.

Baseline HAQ and SF-36 questionnaire scores cannot predict clinical remission, radiographic progression or the need for biological therapy in a three-year prospective study of a Brazilian early rheumatoid arthritis cohort.

This study evaluates prospectively whether baseline scores [Health Assessment Questionnaire (HAQ) and SF-36] can predict clinical and radiographic evolution in a cohort of early rheumatoid arthritis (RA) during a 3-year follow-up. Forty consecutive early RA patients were followed for 3 years, while receiving standardized treatment according to a pre-established protocol. HAQ and SF-36 were administered at the initial evaluation and at 3, 6, 12, 18, 24 and 36 months.

The presence of anti-citrullinated protein antibodies (ACPA) and rheumatoid factor on patients with rheumatoid arthritis (RA) does not interfere with the chance of clinical remission in a follow-up of 3 years.

Autoantibodies in early rheumatoid arthritis (RA) have important diagnostic value. The association between the presence of autoantibodies against cyclic citrullinated peptide and the response to treatment is controversial. To prospectively evaluate a cohort of patients with early rheumatoid arthritis (<12 months of symptoms) in order to determine the association between serological markers (rheumatoid factor (RF), anti-citrullinated protein antibodies) such as anti-cyclic citrullinated peptide antibodies (anti-CCP) and citrullinated anti-vimentin (anti-Sa) with the occurrence of clinical remission, forty patients diagnosed with early RA at the time of diagnosis were evaluated and followed for 3 years, in use of standardized therapeutic treatment.

Head Up Tilt Testing: An Appraisal of Its Current Role in the Management of Patients with Syncope.

Head up tilt testing (HTT) is now commonly used to investigate otherwise unexplained syncope and presyncope. This test has been used for over 20 years primarily to diagnose neurally mediated syncope, but HTT's exact role in the diagnostic process remains uncertain. Recognized limitations include poor reproducibility, lack of prognostic role, and insufficient randomized studies to guide therapeutic choice.

Fatigue in systemic lupus erythematosus: an association with reduced physical fitness.

Systemic lupus erythematosus (SLE) is an autoimmune disease that is characterized by fatigue; however, little research has been performed to identify non-pharmacological strategies, such as physical exercise, that can be employed in the prevention and treatment of fatigue in patients with SLE. Moreover, it is not clear whether physical fitness (defined here as cardiovascular fitness and muscle strength) and functional capacities are related to SLE-associated fatigue. Here, we review the studies, mechanisms and results that relate to SLE-associated fatigue.

Laboratory characteristics of a cohort of patients with early rheumatoid arthritis.

Introduction/objective: To characterize a population of patients with early rheumatoid arthritis (RA) according to laboratory aspects, comparing it with other similar cohorts.

Methods: Data presented are part of a prospective incident cohort study that evaluated 65 patients with early RA, followed for 36 months from the diagnosis at Early Rheumatoid Arthritis Clinic of Hospital Universitário de Brasília (HUB). We recorded demographics, clinical, and laboratory data relevant to the cohort initial assessment, including red blood cells, evidence of inflammatory activity, and presence of autoantibodies (rheumatoid factor (RF)), cyclic citrullinated peptide antibodies (anti-CCP), and antivimentin citrullinated (anti-Sa).

Prospective evaluation of the quality of life in a cohort of patients with early rheumatoid arthritis.

Introduction: Few studies have prospectively assessed the tools used to measure quality of life, both generic and specific, in patients with early rheumatoid arthritis (RA).

Objective: The objective of this study was to characterize a population of patients with early RA (less than 12 months after symptom onset at the time of the diagnosis) prospectively followed for the pattern of responses to questionnaires addressing quality of life, the Health Assessment Questionnaire (HAQ) and Medical Outcomes Study SF-36 Health Survey (SF-36).

Patients And Methods: Forty patients with early RA at the time of diagnosis, treated with a standard treatment regimen, were prospectively followed for 3 years.
