AI Article Synopsis
- Rheumatoid arthritis (RA) is an autoimmune disease that can cause inflammation and lead to anemia, and this study explores how certain soluble receptors are affected in different RA patient subgroups based on anemia types and iron levels.
- The findings show higher levels of sRAGE and sRANKL in patients with anemia of chronic disease combined with iron deficiency anemia (ACD/IDA), while OPG levels decreased, indicating potential differences in disease effects between anemia types.
- The study concludes that soluble receptors like sRAGE, sRANKL, and OPG could serve as biomarkers in RA patients, helping to identify those at risk for anemia and better understand the condition's progression.
Article Abstract
Rheumatoid arthritis (RA) is an inflammatory autoimmune disease with articular and systemic manifestations, and one of the most common is anemia. This study aims to investigate whether the levels of the soluble receptors sRAGE, sRANKL, and OPG are affected by the distribution of RA patients in subgroups according to soluble transferrin receptor/log ferritin (sTfR-F index) and hemoglobin (Hb) levels and to examine their correlation with indicators of iron metabolism, disease activity, and autoimmune and inflammatory changes. The levels of sRANKL and sRAGE were significantly higher in the subgroup of anemia of chronic disease combined with iron deficiency anemia (ACD/IDA) compared to the ACD group: < 0.0001 and < 0.0001. The level of OPG tended to decrease in ACD/IDA ( = 0.053). sRAGE was positively correlated with prohepcidin, RF and anti-CCP antibodies, sRANKL, CRP, and IL-6 only in the ACD group. A negative correlation was found between sRAGE, sRANKL, and serum iron only in the ACD/IDA group. sRANKL was positively correlated with OPG, prohepcidin, CRP, IL-6, RF, anti-CCP antibodies, and DAS28 only in the ACD group. Positive correlations were observed between OPG and ferritin, sTfR, CRP, IL-6, RF, and DAS28, and a negative correlation was observed with serum iron only in the ACD group. Therefore, the investigated soluble receptors may serve as reliable biomarkers involved in the pathogenesis of RA and may contribute to the identification of patients at risk of developing combined anemia.

Introduction: The clinical, research and advocacy communities for Rett syndrome are striving to achieve clinical trial readiness, including having fit-for-purpose clinical outcome assessments. This study aimed to (1) describe psychometric properties of clinical outcome assessment for Rett syndrome and (2) identify what is needed to ensure that fit-for-purpose clinical outcome assessments are available for clinical trials.
Methods: Clinical outcome assessments for the top 10 priority domains identified in the Voice of the Patient Report for Rett syndrome were compiled and available psychometric data were extracted.

CNN-based techniques have achieved impressive outcomes in medical image segmentation but struggle to capture long-term dependencies between pixels. The Transformer, with its strong feature extraction and representation learning abilities, performs exceptionally well within the domain of medical image partitioning. However, there are still shortcomings in bridging local to global connections, resulting in occasional loss of positional information.

The objective was to study the incidence of acute primary angle closure (acute PAC) during pharmacologic mydriasis before cataract surgery and changes in anterior chamber angle parameters in patients with primary angle closure diseases (PACD) with and without prophylaxis laser peripheral iridotomy (LPI). This was a prospective, comparative study of cataract patients with PACD with and without prophylaxis LPI presented at the Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand during June 2022 to December 2023. The incidence of acute PAC during pharmacologic mydriasis prior to cataract surgery was recorded.

Purpose: To explore the significance of changes in anterior chamber depth (ΔACD) and astigmatism between 4 and 8 weeks following uneventful phacoemulsification.
Patients And Methods: Anterior chamber depth (ACD, mm), autorefractometry and subjective refraction were monitored in pseudophakic eyes implanted with non-toric IOLs (group 1, SA60AT, n=36; group 2, SN60WF, n=34; group 3, ICBOO, n=16) and phakic control group (n=30, group 4a, for ACD and autorefractometry) over four weeks. Changes in subjective refractions were compared with repeatability in normal phakic eyes (n=30, group 4b).
