The stent thrombosis in Belgium (STIB) scoring system reliability in Indonesia patients and the modified STIB scoring (M-STIB)

IntroductionClopidogrel is recommended as an alternative to Acetyl Salicylic Acid (ASA), the first-line drug for secondary stroke prevention. Clopidogrel resistance in Indonesia is reportedly 15.8%. The Stent Thrombosis in Belgium (STIB) is a scoring system proposed to assess clopidogrel resistance which has not been tested for the reliability in Indonesian population.ObjectivesThe objective of the study is to test the reliability of the STIB scoring and modified-STIB scoring system in Indonesian population.MethodsThis study was conducted cross-sectionally in Dr. Cipto Mangunkusumo Hospital and Universitas Indonesia Hospital from January 2020 to December 2021. Laboratory examinations of human CYP450 concentration in blood plasma from 112 subjects were carried out using the ELISA method. The clopidogrel resistance test was carried out using the VerifyNow method.ResultsOut of 112 ischemic stroke patients in this study, 14.3% of them did not respond to clopidogrel. Cross-tabulation between the STIB score and clopidogrel resistance showed significant results (p < 0.05) on the Hb variable and a combination of two or three factors involving Hb levels. Both Hb and CYP450 levels can be independent factors predicting clopidogrel resistance. Once combined, the Hb and CYP450 cutoff levels of 458.9 pg/mL had a sensitivity of 100% with a specificity of 30.2%.ConclusionsSTIB scoring system did not prove to be reliable in screening for Clopidogrel resistance in Indonesian population. The modified STIB scoring system proposed in this study showed a promising result. Further research with larger population should be conducted.

Development and validation of an OMERACT ultrasound scoring system for the extent of calcium pyrophosphate crystal deposition at the joint level and patient level.

The Calcium Pyrophosphate Deposition (CPPD) subgroup of the Outcome Measures in Rheumatology (OMERACT) Ultrasound working group was established to validate ultrasound as an outcome measure instrument for CPPD, and in 2017 has developed and validated standardised definitions for elementary lesions for the detection of calcium pyrophosphate crystals in joints. The aim of this study was to develop and evaluate the reliability of a consensus-based ultrasound scoring system for CPPD extent, representing the next phase in the OMERACT methodology. In this study the novel scoring system for CPPD was developed through a stepwise process, following an established OMERACT ultrasound methodology. Following a previous systematic review to gather available evidence on existing scoring systems for CPPD, the novel scoring system was developed through a Delphi survey based on the expert opinion of the members of the OMERACT Ultrasound working group-CPPD subgroup. The reliability of the scoring system was then tested on a web-based and patient-based exercise. Intra-reader and inter-reader reliability of the new scoring system was assessed using weighted Light's κ coefficients. The four-grade semiquantitative scoring system consisted of: grade 0 (no findings consistent with CPPD), grade 1 (≤3 single spots or 1 small deposit), grade 2 (>3 single spots or >1 small deposit or ≥1 larger deposit occupying ≤50% of the structure under examination in the reference image-ie, the scanning view with the highest grade of depositions), and grade 3 (deposits that occupy more than 50% of the structure under examination in the reference image). The score should be applied to the knee (menisci and hyaline cartilage) and the triangular fibrocartilage complex of the wrist. The intra-reader and inter-reader reliabilities on static images were almost perfect (κ 0·90 [95% CI 0·79-1·00] and κ 0·84 [0·79-0·88]), and on the eight patients recruited (four [50%] female and four [50%] male) were substantial (κ 0·72 [95% CI 0·47 to 0·96] and 0·66 [0·61 to 0·71]). This OMERACT ultrasound scoring system for CPPD was reliable on both static images and patients. The scoring system might be a valuable tool for ensuring valid and comparable results in clinical trials and could help monitor the extent of crystal deposition in patients with CPPD in clinical practice.

The Relationship of Olecranon Apophyseal Ossification and Sanders Hand Scores with the Timing of Peak Height Velocity in Adolescents.

The onset of peak height velocity (PHV) guides the timing of interventions in the growing child. The purpose of the present study was to validate the Diméglio olecranon grading system and to compare these scores with the Risser/triradiate closure (TRC), proximal humerus, and Sanders hand scores. Eighty children with annual serial radiographs were selected from the Bolton-Brush collection. The olecranon apophysis was graded with use of lateral radiographs of the elbow. The mean age to PHV was determined for each stage, and reliability was calculated with use of an intraclass correlation coefficient (ICC). Olecranon stage was combined with age, sex, and height in a generalized estimating equation (GEE) model to predict PHV. Predictive performance of this model was evaluated with use of tenfold cross-validation such that the model was trained on 90% of the radiographs and was asked to predict the PHV of the remaining 10%. PHV is closely associated with olecranon stage, with stage 1 occurring 3.0 years before PHV and stage 7 occurring 3.4 years after PHV. Stage 5 was found to occur at PHV. Scoring system reliability was high across an array of observers (ICC = 0.85 ± 0.07). The GEE model showed that this olecranon system outperforms the Risser/TRC system in predicting PHV and is comparable with the humerus and Sanders hand systems. When combined with age and sex, the olecranon system successfully predicted PHV such that 62% of PHV predictions were accurate within 6 months and 90% of PHV predictions were accurate within a year. Our data show that stage 5 occurs at PHV, contrary to previously published data. When combined with age and sex, the olecranon system successfully predicts PHV within a year in 90% of cases, establishing a single lateral view of the olecranon as a simple alternative to more complex grading systems. Last, we describe novel 3 variations in olecranon morphology and provide a guide for accurate olecranon staging. Understanding PHV is critical in the treatment of many pediatric orthopaedic disorders. The revised olecranon staging system will allow for more accurate determination of this variable.

Balance Error Scoring System Reliability and Validity When Performed With Ice Skates

In equipment-heavy sports, there is a growing need to evaluate players in the condition in which they participate. However, the psychometric properties of the Balance Error Scoring System (BESS) while wearing skates remains unknown. Seventy-four adolescent male hockey players completed the BESS with and without skates. A subset was reevaluated at the conclusion of the season. The BESS while wearing skates resulted in a mean of 15 more total errors than the traditional administration (t73 = 14.94, p &lt; .001; ES = 1.95) and demonstrated low test-retest reliability. The BESS should be administered in the traditional manner (without skates).

Re-examination of Koppitz' Developmental Bender Scoring System.

The Koppitz Developmental Scoring System for the Bender-Gestalt test was re-examined using 289 randomly selected children from Grades 1, 3, and 6 of the Northern Arizona area. Data were obtained for scorer reliability and scoring-system reliability. Koppitz items as predictors of the Stanford Achievement Test reading scores were checked. Although significant correlations were obtained between total Koppitz scores and reading achievement, the magnitudes were too low for individual prediction. More than half of the Koppitz items were not discriminators at any one grade, 7 were significant at Grade 1, 2 at Grade 3, and 2 at Grade 6. No items differentiated all grades. Consequently, the Koppitz items should be used carefully and not as the sole indicator of reading problems
