Reliability of Uroflowmetry Pattern Interpretation in Adult Women.

Uroflowmetry is often used to assess lower urinary tract symptoms (LUTS). Criteria for characterization of flow patterns are not well established, and subjective interpretation is the most common approach for flow curve classification. We assessed the reliability of uroflowmetry curve interpretation in adult women. Uroflowmetry studies were obtained in 296 women who participated in an observational cohort study. Four investigators with expertise in female LUTS and urodynamics reviewed and categorized each tracing for interrater reliability. A random subset of 50 tracings was re-reviewed by each investigator for intrarater reliability. The uroflowmetry tracings were rated using categories of continuous, continuous fluctuating, interrupted, and prolonged. Other parameters included flow rate, voided volume, time to maximum flow, and voiding time. Agreement between raters is summarized with kappa (k) statistics and percentage where at least three raters agreed. The mean age of participants was 44.8 ± 18.3 years. Participant age categories were 18-24 years: 20%; 25-34 years: 17%; 35-64 years: 42%; 65+ years: 18%. Nine percent described their race as Asian, 31% Black, 62% White, and 89% were of non-Hispanic ethnicity. The interrater reliability was highest for the continuous flow category (k = 0.65), 0.47 for prolonged, 0.41 for continuous fluctuating, and 0.39 for interrupted flow curves. Agreement among at least three raters occurred in 74.3% of uroflow curves (69% for continuous, 33% for continuous fluctuating, 23% for interrupted, and 25% for prolonged). For intrarater reliability, the mean k was 0.72 with a range of 0.57-0.85. Currently accepted uroflowmetry pattern categories have fair to moderate interrater reliability, which is lower for flow curves that do not meet "continuous" criteria. Given the subjective nature of interpreting uroflowmetry data, more consistent and clear parameters may enhance reliability for use in research and as a screening tool for LUTS and voiding dysfunction.

Evidence Synthesis and Clinical Recommendations for Supporting School Students With Sensory Processing Challenges: A Rapid Review.

Children with sensory processing challenges often need supports to access, participate in, and achieve at school. However, research on best practice is varied, presenting difficulty for practitioners to assess the appropriateness of each support. To provide evidence-informed recommendations regarding best practices in school-based supports for students with sensory processing challenges via a Rapid Evidence Assessment of current literature. Searches were run in CINAHL Complete, Education Research Complete, ERIC, MEDLINE, PsycINFO, and Scopus (for articles published 2010 to 2023). Informed by a 2010 review, articles citing publications identified in the prior review were also included. A reviewer screened the title and abstract of each article for inclusion, and another screened the full texts, with 10% of each reviewer's articles assessed by the other. Interrater reliability was excellent. The review included 61 articles, with only 15% constituting good evidence (38% provided adequate evidence, 31% provided poor evidence, and 16% were reviews). No support could be wholly recommended without caveats, but there was some evidence that sound amplification systems, alternate seating, and multisensory environments may be beneficial in certain conditions or with certain populations. The use of weighted vests is not recommended. Most research had small sample sizes and inconsistent protocols, highlighting the importance of ongoing research. Evidence-informed practitioners should review research findings carefully and integrate evidence from comprehensive clinical assessment and understanding of the child, school, and family contexts when assessing the appropriateness of a support for each student. Plain-Language Summary: Children with sensory processing challenges often need supports to access, participate in, and achieve at school. Occupational therapists provide school-based supports for children with sensory processing challenges with the goal of enabling access, participation, and achievement. It is difficult, however, for practitioners to assess the appropriateness of each support because research on best practice varies. This review of the current literature provides practitioners with evidence on supports for school children with sensory processing challenges to inform decision-making and the selection of appropriate supports for their clients. When assessing the appropriateness of a support for a student, practitioners should carefully review current research findings and integrate evidence from comprehensive clinical assessments along with an understanding of the student, school, and family contexts.

Curved multiplanar reformatting allows the accurate histological delineation of hippocampal subfields.

Hippocampal subfields perform specific roles in normal cognitive functioning and have distinct vulnerabilities in neurological disorders. However, measurement of subfields with MRI is technically difficult in the head and tail of the hippocampus. Recent studies have utilized curved multiplanar reconstruction (CMPR) to improve subfield visualization in the head and tail, but this method has not yet been applied to histological data. We utilized BigBrain data, an open-source database of serially sectioned histological data for our analyses. The left hippocampus was segmented according to histological criteria by two raters in order to evaluate intra- and inter-rater reliability of histology-based segmentation throughout the long axis. Segmentation according to our previous protocol for the hippocampal body was then compared to these histological measurements to evaluate for histological validity. Agreement between segmentations was evaluated using Dice similarity coefficients (DSCs). Intra-rater reliability (DSCs) of histological segmentation was excellent for all subfields: CA1 (0.8599), CA2 (0.7586), CA3/CA4/DG (0.8907), SLM (0.9123), subiculum (0.8149). Similarly, inter-rater reliability analysis demonstrated excellent agreement (DSCs) for all subfield locations: CA1 (0.8203), CA2 (0.7253), CA3/CA4/DG (0.8439), SLM (0.8700), subiculum (0.7794). Finally, histological accuracy (DSCs) for our previous protocol was excellent for all subfields: CA1 (0.8821), CA2 (0.8810), CA3/CA4/DG (0.9802), SLM (0.9879), subiculum (0.8774). When subfields in the hippocampus head, body, and tail were analyzed independently, DSCs also showed excellent agreement. CMPR allows reliable subfield segmentation based on histological criteria throughout the hippocampal head, body, and tail. Our previous protocol for the hippocampal body can be applied to provide histologically valid subfield measurements throughout the entire hippocampal long axis.

Evaluation of Intervertebral Disc Space Width Between 10th and 11th Thoracic Vertebrae in Cats Using Radiography and Magnetic Resonance Imaging.

It is well known that the T10-T11 intervertebral disc space is usually narrower than the adjacent intervertebral disc spaces in most dogs. However, whether the T10-T11 disc space is narrower than the adjacent disc spaces is not well-established in cats. To measure the intervertebral disc space width of the T10-T11 disc space and to compare it with that of the adjacent disc spaces using radiography and magnetic resonance imaging (MRI). In Groups 1 (101 clinically normal cats) and 2 (32 cats without spinal diseases from T8 to T13), dorsal width (DW), central width (CW) and ventral width (VW) of the T8-T13 disc spaces were measured by radiography or MRI. Significant differences of the DW, CW and VW among disc spaces measured by radiography and MRI were evaluated. Intra- and interobserver reliabilities were measured by intraclass correlation coefficient. In Groups 1 and 2 using radiography, the DW and CW of the T10-T11 disc space were significantly narrower than those of adjacent disc spaces (p<0.05). The DW of the T8-T12 disc spaces was significantly narrower than that of the T12-T13 disc space in Group 1 using radiography. In Groups 1 and 2 using radiography, the CW and VW of the T8-T11 disc spaces were significantly narrower than those of the T11-T13 disc spaces. In Group 2 using MRI, the DW of the T10-T11 disc space was significantly narrower than that of the T11-T13 disc spaces. The VW of the T8-T11 disc spaces was significantly narrower than that of the T11-T13 disc spaces. The T10-T11 intervertebral disc space on radiography is statistically narrower than the adjacent intervertebral disc spaces in normal cats. The cranial thoracic intervertebral disc spaces (T8-T11) are usually narrower than the caudal thoracic intervertebral disc spaces (T11-T13) on radiography and MRI.

Modification of McGill Oximetry Score in Improving the Diagnostic Capability of Paediatric OSA.

This study aimed to devise a modified oximetry scoring system and calculate its diagnostic accuracy in detecting paediatric obstructive sleep apnoea syndrome (OSAS). This prospective diagnostic accuracy study was divided into two phases. The study was conducted at a quaternary teaching hospital. Polysomnograms performed from 1 April 2014 to 31 December 2021 were included. In Phase 1, the parameters of 95 oximetry trend graphs were evaluated, and a modified scoring system was constructed. In Phase 2, the modified scoring system was employed in 272 oximetry trend graphs, and its diagnostic accuracy was determined. A logistic regression model was used to assess the ability of each scoring system to predict paediatric OSAS. A total of 367 patients were recruited. In Phase 1, a four-tier severity classification system was constructed. In Phase 2, its diagnostic accuracy was found to be 53.3% sensitive, 97% specific, with positive predictive value of 98.5% and negative predictive value of 34.6%. The lowest detectable apnoea-hypopnoea index (AHI) was 4.5. The inter-rater reliability calculated was 80%. Logistic regression was applied to assess associations of the modified McGill score (MMS) or McGill oximetry score (MOS) with OSAS. The area under the receiver operating characteristic curve was higher for the MMS than for MOS (0.78 [95% CI 0.73-0.84] vs. 0.59 [95% CI 0.51-0.66]). This study demonstrated that our modified scoring system had increased sensitivity at detecting OSAS at a much lower AHI and showed a much greater ability to predict paediatric OSAS.

Surgeon Review of 4D CT for Identification of Parathyroid Adenomas.

Preoperative localization of parathyroid adenomas aids surgical planning for patients with hyperparathyroidism. This study explores the diagnostic accuracy of surgeon-reviewed 4D computed tomography (4D CT) scans for localization of parathyroid adenomas. A retrospective review of 95 patients with hyperparathyroidism who underwent parathyroidectomy at a tertiary care center was performed. The sensitivity, specificity, positive and negative predictive values, accuracy of identifying abnormal glands by surgeon, and interrater reliability between two head and neck surgeons was assessed. The sensitivity of surgeon localization of all glands was 71% (95% CI, 63%-78%), improving to 76% when combined with radiology reads. The specificity was 98% (95% CI, 95%-99%), the positive predictive value was 95% (95% CI, 90%-99%), and the negative predictive value was 84% (95% CI, 79%-88%) for all abnormal glands. Interrater reliability between surgeons was κ = 0.771. The diagnostic accuracy of surgeon localization of abnormal glands on the 4D CT scan was substantial. Improvement with radiology report integration highlights the benefits of multidisciplinary collaboration. Interrater reliability between two fellowship-trained surgeons was moderate. These findings support the importance of surgeons developing proficiency in reading 4D CT scans to engage in interdisciplinary communication and improve patient outcomes.

Variability of pre-test probability for obstructive coronary artery disease between referring primary care physicians and estimations from the referral letters

Abstract Background Estimation of Pre-Test Probability (PTP) for obstructive Coronary Artery Disease (CAD), derived from sex, age and characterization of chest pain or dyspnea, is recommended by European guidelines to guide further investigation. When Coronary Computed Tomography Angiography (CCTA) was introduced as first line investigation in patients with PTP &amp;lt;15%, in the primary care of a catchment area of ~470 000 inhabitants in Sweden, attachment of PTP was made compulsory to the referral. The interrater variability, or consistency of agreement, of PTP estimation is not known. The validity of PTP to guide healthcare decisions depends to some extent on the reliability of estimations. Appropriate prioritization of invesigations is reliant on the information included in referral letters. Purpose The purpose was to study the interrater variability of estimations of PTP. We hypothesized: 1) the interrater variability of PTP estimations to be less than excellent (ICC &amp;lt; 0.9), and 2) not statistically different among PTP classes; 3) a significant difference between clinical estimations and estimations made from the referral letters. Methods We studied the 545 patients referred for CCTA from primary care, 1st of June 2021 to 7th of Dec. 2022, with available PTP estimations. The interrater variability, expressed as Intraclass Correlation Coefficients (ICC), was determined for estimations of PTP by the referring physicians (RP) and three external raters (ER). The latter were physicians practising in primary care who rated PTP based on the referral letters to CCTA, independently and blinded. Each rater assessed multiple patients and each patient was assessed by all raters. ICC with a two-way random consistency model for single raters was calculated and evaluated according to a proposed standard(1). Results The ICC for PTP estimations between the RP and the median of three ER was 0.75 (CI 95 % 0.71-0.83, p&amp;lt;0.001). ICC was higher for PTP class &amp;gt; 15% compared to the lower classes: &amp;lt;5% (n = 65, ICC ≈ 0); 5-15% (n = 343, ICC 0.48, CI 95 % [0.39-0.56]); &amp;gt;15% (n = 137, ICC 0.71, CI 95 % [0.62-0.78]) (Figure 1). The ICC for PTP estimations was significantly higher between the three ER (0.88, SE 0.009, CI 95% [0.86-0.89]) than when the RP was added as a rater (ICC 0.80, SE 0.012, CI 95 % [0.77-0.82]). Adding a fixed effect of the difference in ratings between RP and ERs to the ICC model did not change model output (R = 0.80 (SE 0.012, CI 95 % [0.77-0.82]). Conclusions There is a good repeatability, in estimation of PTP based on medical history as described in referral letters, between blinded independent reviewers of CCTA referrals. The repeatability between the external raters and the referring physicians’ compulsory entered PTPs is lower, yet good. The variability of PTP estimations, speculatively from disagreement on main symptom and inconsistency in characterization of chest pain, may impact patient selection and outcomes and is understudied.

Creation and Validation of the Facial Diplegia Scale for Assessment of Bilateral Facial Palsy.

Objectives: House-Brackmann (HB) classification and the Sunnybrook Facial Grading System (SFGS), both reference tools for the assessment of facial palsy, are not suitable for bilateral facial palsy. The aim of this study was to develop, standardize, and validate the Facial Diplegia Scale (FDS). Methods: The FDS was standardized in a healthy population (n = 111) and validated in 40 patients with diplegia. Correlations with the SFGS were sought to prove its criterion validity. The comparison between healthy subjects and patients with diplegia was used to test the construct validity. The diagnostic performance of the FDS was verified using an ROC curve based on the HB classification. Internal and external consistency were investigated. Results: The FDS and the SFGS were significantly correlated for the right hemiface [F(39) = 51.51, p < 0.0001, R2 = 0.575] as well as for the left one [F(39) = 95.10, p < 0.0001, R2 = 0.714]. A significant difference between control subjects and patients with diplegia was found [t(149) = -9.95, p < 0.0001]. Good specificity and sensitivity were confirmed. Finally, internal consistency, inter-rater reliability, and test-retest reliability were largely proven. Conclusions: The FDS has been standardized and validated for the subjective assessment of facial diplegia in adults to improve comprehensive assessment.

Development of a tool to assess the compliance of canteen menus with the Mediterranean Diet

Abstract The Mediterranean Diet (MD) is one of the healthiest food patterns associated with important health benefits. Acknowledging this, it’s important to understand how the dietary patterns of the consumers align with the MD. Over time, different authors have formulated several indexes for this purpose. However, current indexes lack standardization, and they only evaluate the quality of the diet of individuals to be used by health professionals and political decision-makers. Although there are indexes to assess the food options at the restaurants, none of them assess the menu compliance with the MD. Due to the importance of the food services in the food choices and dietary patterns of the consumers, this research developed an index to assess the alignment of the food availability with the MD key points. To address this gap, after reviewing the existing indexes in the literature, the authors created a tool that assesses the degree of compliance of menus with the MD - MedCIn. This index is divided into 4 dimensions, the first one assesses the availability (part A) and variety (part B) of the food/food groups. The second dimension assesses the nutritional quality of the menus based on the nutritional declaration, the third dimension assesses the food portions and culinary options, and the fourth dimension allows the verification of the previous information on site. Although the use of all dimensions allows for a more comprehensive menu evaluation, dimension one can be used as a first approach MD compliance. The index is meant to be applied in a 4-week cycle, though it can be adapted for each food service. Validation of this tool included construct validity, internal consistency and inter-rater reliability, all of which returned high values (alpha-Cronbach=0.88; Coheńs Kappa=0.92). The researchers consider this a reliable tool to easily assess compliance of menus with MD key points, allowing for the identification of issues to be addressed and improved

Aortic integral distensibility based on the auto-segmented dynamic motion of the aortic wall

Abstract Background Aortic stiffness is important in cardiovascular diseases and predicting outcomes. Echocardiography is a widely used noninvasive imaging modality for assessing aortic stiffness, but its accuracy can be limited by the low spatial resolution of ultrasound-based images and the subjectivity of manual measurements of aortic dimensions. Automated segmentation analysis can provide a more accurate and objective measure. Objective An automated algorithm and software have been developed for segmenting the aortic wall. A new measurement technique called "Aortic Integral Distensibility (AID)" has been formulated using this framework. This method overcomes limitations of traditional method focusing solely on the two positions of Aortic Distensibility (AD). Method In this particular investigation, 112 participants were subjected to echocardiography in order to quantify the dynamics of the aortic wall. An automated algorithm was devised to delineate the aortic wall by utilizing an M-mode echocardiography scan. The statistical analysis encompassed the measurement of AD and AID before and after the age of 65 group. This analysis was conducted considering various risk factors, including age, gender, weight, BMI, smoking, and blood pressure. Additionally, clinical parameters, specifically AIx @75 (Augmentation Index) and Framingham Risk Score (FRS), were evaluated as well. Inter-rater reliability was conducted between the traditional AD and the newly implemented AID. Results The results indicate that the group under 65 had more distensibility than the group over 65, and AID measurements were slightly higher than AD measurements. SBP showed a strong correlation with AID, rather than AD. AIx @75 and FRS had a negative relationship with distensibility. In the 65 years or older group, there was a significant negative correlation observed between AIx @75 and AID (r = -0.4, p = 0.012). Furthermore, a strong correlation was also observed between FRS and AID (r = -0.53, p = 0.002). Bland-Altman analysis demonstrated that the automated methodology had better reproducibility and less variability in distensibility measurements than the manual methodology. Conclusion The study suggests that AID could be valuable for assessing aortic stiffness. AID could help clinicians diagnose and manage cardiovascular diseases more accurately. The automatic approach provides reliable measurements for aortic distensibility and strain, which has clinical implications.Schematic Chart of the Study Process

Tiktok as a Source of Education and Misinformation in Lichen Sclerosus.

The purpose of this study is to evaluate the content, delivery, and quality of medical information for vulvar lichen sclerosus on the social media platform TikTok. This is a descriptive, cross-sectional study. Using the third-party data scraping tool Apify, TikTok videos tagged with #lichensclerosus or "lichen sclerosus" were identified and sorted by view count. A sample of 100 videos was reviewed by 2 independent reviewers, excluding those not discussing lichen sclerosus. Videos were assessed using a coding document, the Patient Educational Materials Assessment Tool, and the DISCERN instrument. Interrater reliability was measured, and statistical analyses included Fleiss' kappa, intraclass correlation coefficient, t tests, and Wilcoxon rank sum test with Holm-Bonferroni correction. Content creators included patients (46%), health care professionals (30%), and others. Topics focused on clinical disease (52%) and treatment (48%). Evidence-based medicine was discussed in 71.7% of treatment-related videos, while 51.7% included nonevidence-based approaches, with a neutral or positive sentiment. Videos discussing topical steroids often had negative sentiments. Quality assessment revealed 61% of videos were understandable, 27% actionable, and 46% contained misinformation. Videos by health care professionals had less misinformation and higher quality scores compared to patient-generated content. Commercially biased videos were more understandable but contained more misinformation. TikTok serves as a significant platform for sharing information on lichen sclerosus, but nearly half of the content contains misinformation. Health care professionals need to engage in social media to provide accurate information and counteract misinformation. Enhanced collaboration with patient advocates and careful resource sharing can improve the quality and reliability of medical information available online.

Assessment of meniscal extrusion with ultrasonography: a systematic review and meta-analysis

BackgroundMagnetic resonance imaging (MRI) is the imaging of choice for meniscal extrusion (ME). However, they may underappreciate the load-dependent changes of the meniscus. There is growing evidence that weight-bearing ultrasound (WB US) is more suitable, particularly in revealing occult extrusion. We therefore perform a systematic review and meta-analysis on the validity and reliability of US in diagnosing extrusion. Furthermore, we explored whether it detects differences in extrusion between loaded and unloaded positions and those with pathological (osteoarthritis and meniscal injury) and healthy knees.MethodsThe Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Data pertaining to intra- and interrater reliability of US in measuring meniscal extrusion (ME), its correlation with magnetic resonance imaging (MRI), and head-to-head comparison of potential factors to influence ME were included [loading versus unloading position; osteoarthritis (OA) or pathological menisci (PM) versus healthy knees; mild versus moderate–severe knee OA]. Pooled data were analyzed by random or fixed-effects models.ResultsA total of 31 studies were included. Intraclass correlation coefficients (ICC) for intra- and interrater reliability were minimum 0.94 and 0.91, respectively. The correlation between US and MRI was (r = 0.76). US detected ME to be greater in the loaded position in all knees (healthy, p < 0.00001; OA, p < 0.00001; PM, p = 0.02). In all positions, US detected greater extrusion in OA (p < 0.0003) and PM knees (p = 0.006) compared with healthy controls. Furthermore, US revealed greater extrusion in moderate–severe OA knees (p < 0.00001).ConclusionsThis systematic review suggests ultrasonography can play an important role in the measurement of meniscal extrusion, with results comparable to that of MRI. However, to what extent it can differentiate between physiological and pathological extrusion requires further investigation, with an absolute cutoff value yet to be determined. Nevertheless, it is an appropriate investigation to track the progression of disease in those with meniscal pathologies or osteoarthritis. Furthermore, it is a feasible investigation to evaluate the meniscal function following surgery.Level of evidence: IV, Systematic review of level III–IV evidence.

Capability of ChatGPT to support the screening process of scoping reviews: A feasibility study

Abstract Background The time-consuming screening phase in health-related evidence syntheses is increasingly supported by artificial intelligence (AI). However, scoping reviews have not benefited as much as systematic reviews from such AI tools as they utilize conceptual rather than keyword-specific search strategies to address broad research questions. Context-understanding chatbots based on large language models could potentially enhance the efficiency of scoping review screenings. This study evaluates the performance of ChatGPT against an open-access AI tool used for abstract screening in systematic reviews and the costs involved. Methods Leveraging data from a prior scoping review, we compared the performance of ChatGPT 4.0 and 3.5 against Rayyan, using human researchers’ decisions as a benchmark. A random set of 50 included and 50 excluded abstracts was used to train Rayyan’s algorithm and to develop ChatGPT’s prompt. ChatGPT 4.0’s evaluation was repeated after 5-7 days to assess response consistency. We computed performance metrics including sensitivity, specificity, and accuracy. Results ChatGPT 4.0 and 3.5 achieved 68% accuracy, 11% precision, 99% negative predictive value, and 67% specificity. Sensitivity was high at 88-89% for ChatGPT 4.0 and 84% for ChatGPT 3.5. ChatGPT 4.0 showed a substantial interrater reliability between the two evaluations and moderate reliability compared to ChatGPT 3.5. The cost of deployment varied, with Rayyan being free, ChatGPT 3.5 costing $9.06 and ChatGPT 4.0 $505.72. Conclusions Given the exponential increase in publications, effective mechanisms to support the screening phase of scoping reviews are needed. Our feasibility study using ChatGPT to decide on abstracts’ inclusion or exclusion achieved good performance metrics. Given further positive evaluation, such chatbots might be incorporated in the standard screening process, possibly replacing a second screener, saving time and costs, and accelerating evidence synthesis. Key messages • ChatGPT performs well in supporting screening for scoping reviews, outperforming a traditional AI tool at reasonable costs. • Employing chatbots like ChatGPT could potentially cut costs and time in scoping reviews.

Patient-reported outcomes (PROs) programs for monitoring symptoms among patients treated with immunotherapy: A scoping review.

Monitoring toxicities among patients receiving immune checkpoint inhibitors (ICIs) using patient-reported outcome (PRO) measures (PROMs) is relatively recent. This scoping review aims to guide decision-making in the development of PROMs ICI programs. Four electronic databases were searched from inception to January 2024. Data on PROMs ICI programs (eg, PROMs used, frequency) were extracted. Two authors with established inter-rater reliability screened titles, abstracts, and full texts. A narrative synthesis identified patterns in the data. 22 articles described 16 unique multicomponent, electronic PRO programs, mainly developed for remote monitoring of toxicities between appointments. Patients typically completed 18-26 items from the PRO-CTCAE or CTCAE weekly, with high adherence/satisfaction. Commonly monitored symptoms were diarrhea, fatigue, shortness of breath, cough, nausea, decreased appetite, rash, joint pain, pain, and mood. Other features of PROM programs included clinician alerts, with some program only flagging symptoms that had an impact on treatment. Some program also or only sent alerts to patients to contact their clinicians and gave access to symptom management information. In terms of efficacy, the only consistent finding was an increase in QOL. The findings of this scoping review provide some indication as to which components of a PROM program are promising. However, as the evidence-based for PROMs among patients receiving ICIs is growing, many questions remain, including which symptoms to monitor, using which PROM, and at what frequency. More trials are needed to answer these questions and to determine how best to implement PROM ICI programs in clinical practice.

Assessing the return-to-work mode of Dutch precarious workers with mental health issues

Abstract Background Mental health issues are highly prevalent among precarious workers, often leading to sickness absence, work disability, and job loss. Return to work (RTW) is more challenging for these workers, as they often lack a job to return to and have limited access to occupational health care. Perceptions and attitudes about RTW are important determinants and can be categorized into three modes within the RTW process: a passive, an ambivalent and an active RTW-mode. To identify the RTW mode, we developed the RE-MODE tool. This study aimed to assess occupational health professionals’ agreement on the RTW-mode of sick-listed precarious workers with mental health issues using RE-MODE. Methods In a vignette study, 71 occupational health professionals from a Dutch social security institute viewed six videos of consultations between insurance physicians and precarious workers. They then used RE-MODE to assess the RTW mode and need for RTW-support. They also provided feedback on the tool’s validity and usability. We used a generalized linear mixed model to analyze inter-rater agreement, inter-item consistency, and the contribution level of each item. Additionally, we calculated the content validity index and the system usability scale. Results The agreement on the RTW mode with RE-MODE is high (ICC 0.86, 95% CI 0.64-0.95) and on the workers’ need for RTW-support moderate (0.61, 95% CI 0.31-0.84). Furthermore, the content-validity (Scale-CVI 0.83), usability (SUS 0.75), and inter-item consistency (Cronbach’s Alpha 0.70) show favorable results. We are currently analyzing the contribution of each item to the total score. The items with the best overall performance will be included in RE-MODE 2.0. Conclusions REMODE is a valuable tool for occupational health professionals to identify precarious workers with mental health issues at risk of long-term disability. Then they can arrange targeted RTW-support. Based on the study results, RE-MODE 2.0 is in development. Key messages • RE-MODE is a valuable tool for the assessment of the RTW-mode of precarious workers with mental health issues. • RE-MODE’s reliability, content-validity and usability is satisfactory.

Comparison of vessel-Fractional Flow Reserve (vFFR) and Quantitative Flow Ratio (QFR) using instantaneous wave-Free Ratio (iFR) or Resting Full-cycle Ratio (RFR) as reference

Abstract Background Angiography-based functional assessment remains the state of the art to assess the hemodynamic relevance of intermediate coronary stenoses. In addition to fractional flow reserve (FFR), adenosin free indices like instantaneous wave-free ratio (iFR) or resting full-cycle ratio (RFR) are widely used for the invasive evaluation. Although these methods are widely accepted, they are underused in clinical routine due to costs, their invasive nature, longer procedural times, and lack of availability. Vessel-fractional flow reserve (vFFR) and quantitative flow ratio (QFR) are new software-based methods for the evaluation of coronary-physiology. The aim of this study is to compare vFFR and QFR with the established invasive methods iFR or RFR. Methods We prospectively analyzed 95 Patients in our QFR-Registry vFFR- and QFR-computation was performed three-times by two certified, blinded, and independent experts using the QAngio XA 3D 3.2- and CAAS-software, respectively. Results: 101 main epicardial coronary arteries (52 LAD; 19 LCx; 30 RCA) were analyzed using vFFR, QFR and iFR or RFR. vFFR showed a good correlation with adenosine-free indices in all 3 measurements (AUC 0.883 with r=0.672, p&amp;lt;0.001; AUC 0.841 with r=0.618 p&amp;lt;0.001; AUC 0.840 with r=0.592, p&amp;lt;0.001 respectively). The diagnostic accuracy between the three vFFR-measurements and iFR/RFR was 83%; 81% and 79% respectively. QFR-computations showed a similar correlation with iFR/RFR (AUC 0.899 with r=0.720, p&amp;lt;0.001; AUC 0.919 with r=0.649, p&amp;lt;0.001; AUC 0.930 with r=0.703, p&amp;lt;0.001 respectively) with a diagnostic accuracy 88%, 89% and 88% respectively. The intra- and inter-observer reliability for vFFR (intra: mean difference 0.002±0.0568; inter: 0.024±0.054) and QFR (intra: mean difference 0.018±0.071; inter: 0.016±0.075) analyzed in a Bland-Altman Blot showed a good correlation between virtual assessments and invasive measurements with iFR/RFR. Conclusion The data show a good diagnostic agreement between vFFR and QFR and adenosine free invasive assessments. vFFR and QFR appear reasonable alternative approaches for the evaluation of intermediate stenoses. These data provide the rational to prospectively test for a clinical noninferiority of the non-invasive flow measurements.Diagnostic performance of vFFR/cQFR

Validation of a Photonumeric Scale for Evaluation of Telangiectasia in Rosacea.

Telangiectasia is a prominent feature of rosacea leading to a high demand for effective treatment. To ensure consistent clinical and scientific evaluations and assess treatment response accurately, standardized assessment tools are necessary for grading the severity of telangiectasia. However, no validated grading scales for this condition are currently available. To develop and validate a photonumeric scale for assessing the severity of telangiectasia in rosacea patients. The five-point photonumeric Telangiectasia in Rosacea Severity Assessment (TRoSA) scale was developed for the severity of telangiectasia in rosacea. Sixteen experts participated in the validation process, evaluating 50 images of rosacea patients in two rounds. Interrater and intrarater reliability were analyzed using the intraclass correlation coefficient (ICC) and weighted kappa, respectively. Interrater reliability was found to be "almost perfect" in both validation rounds (Round 1: ICC 0.847; Round 2: ICC 0.828). The mean weighted kappa indicated "substantial" intrarater reliability between the two rounds with a weighted kappa of 0.719. A bubble plot of the two rounds illustrated a diagonal order, confirming the consistency of the intrarater agreement. The TRoSA scale demonstrated high interrater and intrarater reliability indicating that it is a consistent and reproducible tool for grading the severity of telangiectasia in rosacea. This scale can standardize clinical assessments, assisting in diagnosis, treatment planning, and evaluation of therapeutic efficacy.

An audit of the indications for peripartum hysterectomies performed at a tertiary institution in Johannesburg, South Africa: A retrospective study.

Peripartum hysterectomy (PH), the surgical removal of the uterus during or shortly after childbirth, is a critical procedure in maternal health care. Definitions of PH vary globally, leading to challenges in understanding its occurrence. Our study aimed to provide comprehensive insights into PH in a South African context, investigating indications, demographic characteristics, clinical and histopathological diagnoses, complications, and outcomes. A retrospective record review study design was used, focusing on PH cases at a tertiary facility in Johannesburg, South Africa (SA), between January 2018 and December 2020. Medical records were systematically examined to identify trends, indications, and outcomes associated with PH. Data collection encompassed demographic characteristics, obstetric history, clinical indications, clinical and histopathological diagnoses, and complications. Data analysis used descriptive statistics, interrater reliability tests, and comparative findings with previous SA studies. The study included 56 pregnant women with a median age of 32 years (interquartile range: 25-35) who underwent PH between January 2018 and December 2020 at Charlotte Maxeke Johannesburg Academic Hospital in South Africa. We found that pregnancy-related sepsis (PRS) emerged as the most common indication of PH, as reported among 18 (32.1%) of the women, with an 88.8% histopathological confirmation rate. Abnormal placentation (14/56, 25%) and PPH (8/56, 14%) were other common indications. Clinical and histopathological diagnoses exhibited a strong level of agreement (70.9%), emphasizing the importance of accurate diagnostics. Our study found a shift in the primary historical indications, such as uterine atony and uterine rupture in South Africa, with PRS emerging as the primary indication in recent years(2009-2020). Clinical assessment complemented by histopathological findings remains critical for improved obstetric complication management.

The Development and Reliability of a Surface Electromyography-Based Index for Quantifying Knee Muscle Coactivation During the Lower Quarter Y-Balance Test

This study aimed to develop and evaluate the reliability of a surface electromyography-based (sEMG) index to quantify knee muscle coactivation in healthy recreational athletes during the Lower Quarter Y-Balance Test (YBT-LQ). A prospective observational repeated measures design was used to assess both intra- and inter-rater reliability. Forty males completed three trials, with two raters independently conducting assessments. sEMG signals from the vastus medialis, vastus lateralis, biceps femoris, and semitendinosus muscles were collected to calculate four coactivation indices (CoAIs) for different muscle pairs. The reliability evaluation of these CoAIs was based on intraclass correlation coefficients. The results revealed that the reliability of the CoAIs varied depending on the muscle pair, direction, and limb examined. The highest intra- and inter-rater reliability was noted for the left lower limb in the posterolateral direction. The lowest reliability was found for the right lower limb in the anterior direction. Statistical analyses indicated significant differences in specific CoAIs across different YBT-LQ directions. These findings highlight the potential of sEMG-based CoAIs for assessing knee muscle activity during the YBT-LQ in healthy male recreational athletes. However, choosing CoAIs is critical for reliable clinical and research assessments of knee stability and neuromuscular control.

Inter-rater Agreement for Movement Disorder Classification in Children with Hyperkinetic Movement Disorders.

Accurate classification is essential for addressing childhood movement disorders (MD), but the common coexistence of multiple MDs complicates this process. The aim was to assess inter-rater agreement on classifying hyperkinetic MDs among pediatric neurologists with expertise in MDs. Five pediatric neurologists were requested to examine 112 videos of 66 pediatric patients. Based on the Movement Disorder-Childhood Rating Scale, 3 queries were posed: (Q1) Is there more than 1 MD? (Q2) What is the (predominant) MD? (Q3) What is the other MD (if present)? The final agreement rates were 57.5% for Q1, 66.6% for Q2, and 43.9% for absolute agreement. All videos with absolute agreement at the first evaluation featured 1 MD, whereas only 2 videos with multiple MDs could totally agree in the final review. This study reveals significant discordance in classification even among pediatric neurologists with expertise in MDs and highlights the necessity for a standardized approach.
