Background This study aimed to assess malnutrition using the Global Leadership Initiative on Malnutrition (GLIM) criteria and Subjective Global Assessment (SGA) at baseline and determine the GLIM criteria that best predicted unplanned hospitalization in outpatients with unintentional weight loss (UWL). Methods We performed a retrospective cohort study of 257 adult outpatients with UWL. The GLIM criteria and SGA agreement were reported using the Cohen kappa coefficient. Kaplan‐Meier survival curves and adjusted Cox regression analyses were used for survival data. Logistic regression was used for the other correlation analysis. Results This study collected data from 257 patients for 2 years. Based on the GLIM criteria and SGA, malnutrition prevalence was 79.0% and 72.0%, respectively (κ = 0.728, P < 0.001). Using the SGA as a standard, GLIM had a sensitivity of 97.8%, a specificity of 69.4%, a positive predictive value of 89.2%, and a negative predictive value of 92.6%. Malnutrition was associated with higher rates of unplanned hospital admission independent of other prognostic factors (GLIM: hazard ratio [HR]=2.85, 95% CI=1.22–6.68; SGA: HR=2.07, 95% CI=1.13–3.79). Of the five GLIM criteria–related diagnostic combinations, disease burden or inflammation was the most important to predict unplanned hospital admission in multivariable analysis (HR=3.27, 95% CI=2.03–5.28). Conclusion There was good agreement between the GLIM criteria and the SGA. GLIM‐defined malnutrition, as well as all five GLIM criteria–related diagnosis combinations, had the potential to predict unplanned hospital admissions in outpatients with UWL within 2 years.

BackgroundLung cancer is a common comorbidity of heart failure (HF). The early identification of the risk factors for lung cancer in patients with HF is crucial to early diagnosis and prognosis. Furthermore, oxidative stress and immune responses are the two critical biological processes shared by HF and lung cancer. Therefore, our study aimed to select the core genes in HF and then investigate the potential mechanisms underlying HF and lung cancer, including oxidative stress and immune responses through the selected genes.MethodsDifferentially expressed genes (DEGs) were analyzed for HF using datasets extracted from the Gene Expression Omnibus database. Functional enrichment analysis was subsequently performed. Next, weighted gene co-expression network analysis was performed to select the core gene modules. Support vector machine models, the random forest method, and the least absolute shrinkage and selection operator (LASSO) algorithm were applied to construct a multigene signature. The diagnostic values of the signature genes were measured using receiver operating characteristic curves. Functional analysis of the signature genes and immune landscape was performed using single-sample gene set enrichment analysis. Finally, the oxidative stress–related genes in these signature genes were identified and validated in vitro in lung cancer cell lines.ResultsThe DEGs in the GSE57338 dataset were screened, and this dataset was then clustered into six modules using weighted gene co-expression network analysis; MEblue was significantly associated with HF (cor = −0.72, p &lt; 0.001). Signature genes including extracellular matrix protein 2 (ECM2), methyltransferase-like 7B (METTL7B), meiosis-specific nuclear structural 1 (MNS1), and secreted frizzled-related protein 4 (SFRP4) were selected using support vector machine models, the LASSO algorithm, and the random forest method. The respective areas under the curve of the receiver operating characteristic curves of ECM2, METTL7B, MNS1, and SFRP4 were 0.939, 0.854, 0.941, and 0.926, respectively. Single-sample gene set enrichment analysis revealed significant differences in the immune landscape of the patients with HF and healthy subjects. Functional analysis also suggested that these signature genes may be involved in oxidative stress. In particular, METTL7B was highly expressed in lung cancer cell lines. Meanwhile, the correlation between METTL7B and oxidative stress was further verified using flow cytometry.ConclusionWe identified that ECM2, METTL7B, MNS1, and SFRP4 exhibit remarkable diagnostic performance in patients with HF. Of note, METTL7B may be involved in the co-occurrence of HF and lung cancer by affecting the oxidative stress immune responses.

Background Health education is one of the crucial part of general practitioners’ (GPs’) responsibility. There are few instruments for measurements of health education quality. This study aimed to develop and validate an instrument to measure the health education quality. Methods The questionnaire is a 6-item scale developed in a multi-level process following a literature review and consultations with specialists. The scale was applied in a sample of N = 152 general practitioners (GPs) in Zhejiang, eastern China. Items and properties were analyzed by determining item reliability as well as performing a confirmatory factor analysis (CFA) to test the instruments dimensionality. The association of health education quality with respondents’ characteristics and attitudes were analyzed by analogue non-parametric test. Spearman correlation analysis was used to clarify the factors related to the quality of health education. Results The HEQ scale demonstrated good internal consistency(α = 0.945). CFA verified a 5-factor structure of the scale. The mean score of the health education quality of participants is 102.78/150. There were significant differences in health education quality and health education attitude between GPs in different level of public healthcare institutions (P<0.05). The score of GPs in healthcare stations (94.58/150) was lower than others. Spearman correlation analysis revealed a significant association between each items and the final HEQ score, and the HEQ score was also significant associated with self-cognition of health education sufficiency(ρ = 0.556,P<0.05), health education skill༈ρ = 0.551,P<0.05). Conclusion The HEQ is a valid scale to assess the extent of the health education quality of GPs, and the health education quality of GPs in Zhejiang province is relatively good. GPs’ health education quality is related to their attitudes toward patient health education. Specific measures should be taken to further improve the health education quality of GPs.
