This systematic review assesses the current status of anti-cyclic citrullinated peptide (anti-CCP) and rheumatoid factor (RF) tests in the diagnosis and prognosis of rheumatoid arthritis (RA). We reviewed publications on tests and biomarkers for early diagnosis of RA from English-language MEDLINE-indexed journals and non-MEDLINE-indexed sources. 85 publications were identified and reviewed, inc...

Interest in cognitive pretest methods for evaluating survey questionnaires has been increasing for the last three decades. However, analysing the features of the scientific output in the field can be difficult due to its prevalence in public and private institutes whose main mission is not scientific research.

The cohort is sponsored by the French Society for Rheumatology (Société française de rhumatologie [SFR]). Betwe...

OBJECTIVE To investigate the relationship between science production and the indexation level of low- and middle-income countries (LAMIC) journals in international databases. METHOD Indicators of productivity in research were based on the number of articles produced over the 1994-2004 period. A survey in both Medline and ISI/Thomson was conducted to identify journals according to their countr...

Background: Iran has achieved rapid scientific growth in the past two decades. Considerable growth in scientific publications by Iranian dermatologists matches the pace of Iran’s scientific publications in the previous decade. In this study, we aim to identify the current trends in Iranian dermatology publications and authorship over the past decade.Methods: We compared papers indexed in the ME...

Predatory open access (OA) journals can be defined as non-indexed journals that exploit the gold OA model for profit, often spamming academics with questionable e-mails promising rapid OA publication for a fee. In aquaculture—a rapidly growing and highly scrutinized field—the issue of such journals remains undocumented. We employed a quantitative approach to determine whether attributes of scie...
