Montreal cognitive assessment as a screening instrument for cognitive impairment in systemic lupus erythematosus patients without overt neuropsychiatric manifestations.

Objectives: The Montreal Cognitive Assessment (MoCA) is an increasingly used screening tool for cognitive impairment. The aim of this study was to examine how MoCA performed in identifying cognitive impairment (CI) domains in SLE patients compared with formal standardized neuropsychological testing (NPT). Factors related to SLE disease, immunologic and psychological state associated with CI were also explored.

Mortality and hospitalization outcomes of interstitial lung disease and pulmonary hypertension in the Singapore systemic sclerosis cohort.

Objectives: We compared mortality and hospitalization rates in four groups of patients with systemic sclerosis (SSc) [isolated pulmonary arterial hypertension (PAH) or interstitial lung disease (ILD), concomitant ILD-pulmonary hypertension (PH), and no/mild pulmonary involvement].

Methods: In the Systemic Sclerosis Cohort Singapore (SCORE), ILD was diagnosed by HRCT and significant ILD was defined by forced vital capacity <70% predicted. Patients were classified as PAH if echocardiographic systolic pulmonary artery pressure (sPAP) ≥50 mmHg or right heart catheterization (RHC) mean PAP ≥25 mmHg.

Validation of the UCLA Scleroderma Clinical Trial Consortium Gastrointestinal Tract Instrument 2.0 in English- and Chinese-speaking patients in a multi-ethnic Singapore systemic sclerosis cohort.

The aim of this study was to (1) translate the Gastrointestinal Tract Instrument (GIT) 2.0 from English to Chinese and (2) validate both versions in a multi-ethnic systemic sclerosis cohort in Singapore (SCORE). The English GIT2.

Achieving consensus in ultrasonography synovitis scoring in rheumatoid arthritis.

Objective: Ultrasonography is sensitive for synovitis detection but interobserver variation in both acquisition and image interpretation is still a concern. The objective was to assess if a short collegiate consensus would improve inter-observer reliability in scoring of synovitis.

Methods: Eight rheumatologists (Singapore) participated in a 1-day consensus meeting divided into: (i) still-image interpretation and consensus followed by; (ii) image acquisition and interpretation, according to definitions and synovitis scoring rules endorsed by Outcome Measures in Rheumatology (OMERACT) and TUI (Targeted Ultrasound Initiative).

Major trends in the manifestations and treatment of rheumatoid arthritis in a multiethnic cohort in Singapore.

We analyzed the epidemiological changes of rheumatoid arthritis (RA) over three decades using patients from a single center in Singapore. All patients who fulfill the 1987 American College of Rheumatology criteria for RA were invited to enroll in a prospective disease registry. We analyzed the patient demographics, disease manifestation, management and patient-reported outcomes, including quality of life (QoL), in the three categories according to the year of disease onset: before 1989 (group I), 1990-1999 (group II) and after 2000 (group III).

Urine sVCAM-1 and sICAM-1 levels are elevated in lupus nephritis.

Aim: We sought to evaluate the relationship of urine levels of soluble cellular adhesion molecules sVCAM-1 (vascular) and sICAM-1 (intercellular) in systemic lupus erythematosus (SLE) patients with or without lupus nephritis, and to explore their correlation with renal disease activity.

Methods: Paired serum and urine samples of 121 Asian SLE patients, and urine samples of 19 normal healthy controls were collected. Demographic data, disease activity and damage scores, and selected laboratory parameters, including levels of anti-double stranded DNA antibody, complements C3, C4, and creatinine were captured.
