Get PDFA comparative cross-sectional study of psychological distress, fatigue, and physical activity in patients with rheumatoid arthritis, systemic lupus erythematosus, and Sjögren's disease
Get PDFIntroduction Anxiety and depression are common in patients with rheumatic diseases, but their impact across conditions like rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and primary Sjögren's disease (SjD) is still not well understood. This study aims to compare depression, anxiety, and fatigue, and their effects on disease activity and physical activity in these conditions. Methods From January 2019 to March 2021, patients with RA, primary SjD and SLE were assessed consecutively in a monocentric cross-sectional study at the rheumatology outpatient clinic of the Hannover Medical School. Standardized questionnaires were used to assess depression, anxiety, fatigue, disease activity, functional impairment, and physical activity in these patients. Results Of 445 patients, 36.9% had RA, 32.8% SLE, and 30.3% SjD, with most being female (RA 76.2%, SLE 85.6%, SjD 87.4%). Depression (28.5%) and anxiety (31.2%) were common, particularly in SLE (28.8%) and SjD (36.3%) vs. RA (22%, p 0.002). Physical inactivity was higher in SLE (44.5%) and SjD (44.4%) than in RA (39.0%), especially in depressed patients (p 0.011). A significant proportion of patients retired early, especially in SLE (85%) and SjD (66%) vs. RA (49%, p 0.001). Disease activity correlated with psychological status (p < 0.05). Conclusions Depression and anxiety are highly prevalent in RA, SLE, and SjD, particularly in SLE and SjD. The study highlights the need for early psychological evaluation and integrated care involving rheumatologists and mental health professionals to address these issues and improve physical and mental well-being
Investigating the associations between early labour onset symptoms and self-diagnosed labour onset in a cohort study of primiparas.
Get PDFObjective The early recognition of possible labour onset symptoms may be pivotal to identifying the beginning of early labour and are usually recognised by the birthing women themselves. The present study illustrates the interrelationship among five labour-onset symptoms and explores the association of these labour-onset symptoms with the self-diagnosed labour onset of primiparas. Methods A prospective cohort study on a sample of 69 primigravida in Giessen, Germany, expecting spontaneous onset of labour at term. The participants filled in a diary from ≥37 + 0 weeks gestation until self-diagnosed labour onset. Descriptive, bivariate and inferential analysis explored association of labour onset symptoms with self-diagnosed labour onset while accounting for maternal and newborn characteristics. Results Self-diagnosed labour onset was positively associated with all symptoms and clinical characteristics, apart from irregular pain and maternal weight and age. Moreover, regular pain was negatively correlated with irregular pain; having regular pain increased the odds of self-diagnosed labour onset substantially (OR: 10.18, 95 % CI: 2.39-66.27), followed by gastrointestinal symptoms (OR: 2.07, 95 % CI: 0.40-13.10) and emotional symptoms (OR: 2.05, 95% CI: 0.30-13.98). Conclusion Being the initiator of intrapartum care without any birth experience, primiparas are prone to experiencing dissatisfaction in care and may enter professional care too late or too early. The present study showed that regular pain may signify primiparas to self-diagnose labour onset within 24 h and indicate early labour symptoms that may be relevant for a self-diagnosed labour onset
Local inconsistency detection using the Kullback-Leibler divergence measure.
Get PDFBackground The standard approach to local inconsistency assessment typically relies on testing the conflict between the direct and indirect evidence in selected treatment comparisons. However, statistical tests for inconsistency have low power and are subject to misinterpreting a p-value above the significance threshold as evidence of consistency. Methods We propose a simple framework to interpret local inconsistency based on the average Kullback-Leibler divergence (KLD) from approximating the direct with the corresponding indirect estimate and vice versa. Our framework uses directly the mean and standard error (or posterior mean and standard deviation) of the direct and indirect estimates obtained from a local inconsistency method to calculate the average KLD measure for selected comparisons. The average KLD values are compared with a semi-objective threshold to judge the inconsistency as acceptably low or material. We exemplify our novel interpretation approach using three networks with multiple treatments and multi-arm studies. Results Almost all selected comparisons in the networks were not associated with statistically significant inconsistency at a significance level of 5%. The proposed interpretation framework indicated 14%, 66%, and 75% of the selected comparisons with an acceptably low inconsistency in the corresponding networks. Overall, information loss was more notable when approximating the posterior density of the indirect estimates with that of the direct estimates, attributed to indirect estimates being more imprecise. Conclusions Using the concept of information loss between two distributions alongside a semi-objectively defined threshold helped distinguish target comparisons with acceptably low inconsistency from those with material inconsistency when statistical tests for inconsistency were inconclusive
Language bias in orthodontic systematic reviews: A meta-epidemiological study.
Get PDFBackground Orthodontic systematic reviews (SRs) include studies published mostly in English than non-English languages. Including only English studies in SRs may result in a language bias. This meta-epidemiological study aimed to evaluate the language bias impact on orthodontic SRs. Data source SRs published in high-impact orthodontic journals between 2017 and 2021 were retrieved through an electronic search of PubMed in June 2022. Additionally, Cochrane oral health group was searched for orthodontic systematic reviews published in the same period. Data collection and analysis Study selection and data extraction were performed by two authors. Multivariable logistic regression was implemented to explore the association of including non-English studies with the SRs characteristics. For the meta-epidemiological analysis, one meta-analysis from each SRs with at least three trials, including one non-English trial was extracted. The average difference in SMD was obtained using a random-effects meta-analysis. Results 174 SRs were included in this study. Almost one-quarter (n = 45/174, 26%) of these SRs included at least one non-English study. The association between SRs characteristics and including non-English studies was not statistically significant except for the restriction on language: the odds of including non-English studies reduced by 89% in SRs with a language restriction (OR: 0.11, 95%CI: 0.01 0.55, P< 0.01). Out of the sample, only fourteen meta-analyses were included in the meta-epidemiological analysis. The meta-epidemiological analysis revealed that non-English studies tended to overestimate the summary SMD by approximately 0.30, but this was not statistically significant when random-effects model was employed due to substantial statistical heterogeneity (ΔSMD = -0.29, 95%CI: -0.63 to 0.05, P = 0.37). As such, the overestimation of meta-analysis results by including non-English studies was statistically non-significant. Conclusion Language bias has non-negligible impact on the results of orthodontic SRs. Orthodontic systematic reviews should abstain from language restrictions and use sensitivity analysis to assess the impact of language on the conclusions, as non-English studies may have a lower quality
