PurposeThe paper aims to investigate the factors influencing cancer-related fatigue (CRF) in lung cancer patients and construct a CRF risk prediction model, providing effective intervention strategies for clinical medical staff.MethodsThis paper employs convenience sampling to select 400 lung cancer patients who visited a tertiary hospital in Dazhou, Sichuan Province, from January 2021 to January 2022. A questionnaire survey was conducted using the Revised Piper Fatigue Scale (PFS-R), Pittsburgh Sleep Quality Index (PSQI), and Hospital Anxiety and Depression Scale (HADS) to collect data on patient demographics and sociological characteristics, disease-related information, physiological indicators, sleep quality, mental health, and other relevant factors. To explore the factors influencing CRF in lung cancer patients, single-factor analysis and multiple logistic regression analysis were performed. A CRF risk prediction model was then established, with its predictive performance and calibration evaluated using ROC curves.FindingsThe results of multivariate logistic regression analysis showed that gender, age, education level, living status, daily exercise, clinical stage, course of disease, treatment mode, chronic disease, BMI, hemoglobin, serum albumin, blood glucose, potassium concentration, magnesium concentration, PSQI score and HAD score were the influencing factors of CRF in lung cancer patients (P0.05 of the model construction group and χ2 = 8.120, P=0.320>0.05 of the model validation group indicated that the model had high prediction accuracy.Originality/valueThe risk prediction model for CRF holds significant clinical value. It can help medical staff to promptly identify high-risk patients, develop personalized intervention strategies, alleviate fatigue symptoms, and improve overall patient quality of life.

Background: Metabolic Syndrome (MS), a known risk factor for Cardiovascular Disease (CVD) and type II diabetes is an emerging epidemic in China. Studies carried out on the general population indicate a varied clustering of cardiovascular risks in many parts of the country. However, there is limited data on its prevalence in the working population. Workplace can serve as an important place for prevention, control and management of CVD risks. The aim of this study was to investigate the prevalence of MS and its components among University workers, and determine how the prevalence varied according to sex and occupation. Methods: This was a cross-sectional study of 2,428 University employees (22-60 years) who received an annual clinical examination at the University hospital. Anthropometric measurements, blood pressure, Fasting Plasma Glucose (FPG), and lipid profiles were measured. MS was defined according to the National Cholesterol Education Program Adult Treatment panel III modified criteria. Results: Overall prevalence of MS was 6.1%, higher in males (5.1%) than females (1.1%), and increased with age. The most prevalent MS components in all workers were hypertension (37.9%) and hypertryglyceridemia (20.8%), corresponding rates in males were 28.3% and 16.1% while females had a prevalence of 9.6% and 4.7%. After adjustment for age, administrative work was associated (p0.05) between the two occupations in both sexes. Conclusions: Prevalence of MS and its components was higher in male workers than in females, increased with age, and were more common in administrative workers. The findings support the need for gender and occupation specific health interventions to prevent CVDs and type II diabetes in the workplace.

In the title coordination polymer, [Sm(C10H13N2O8)(H2O)]n, each samarium(III) centre is nine-coordinated by six O and two N atoms from three N′-(carboxymethyl)ethylenediamine-N,N,N′-triacetate ligands and one O atom of a water molecule, forming polymeric chains running parallel to the a axis. The packing is governed by intermolecular O—H...O hydrogen-bonding interactions.

Background: Oxidative stress plays a role in the pathogenesis of many chronic diseases. It is recognized in overt hypothyroidism while its existence in subclinical hypothyroidism (SCH) is not well established. The aim of this study was to determine whether there was increased oxidation of lipids and proteins in SCH, and examine their association with lipids and thyroid hormones. Methods: Male adults (35-59 years) with SCH (n=467) and euthyroid controls (n=190) were studied. Anthropometric measurements, plasma lipids, thyroid stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), total antioxidant capacity (T-AOC), lipid peroxidation products, malondialdehyde (MDA), advanced oxidation protein products (AOPP) and dityrosine concentrations were measured. Results: Plasma concentrations of MDA were significantly higher (p<0.05) in SCH (8.11±1.39 nmol/mL) compared with euthyroid controls (7.34±1.31 nmol/mL) while AOPP, dityrosine and T-AOC levels were not different. MDA was not associated with TSH (ß=-0.019, P=0.759), FT4 (ß=-0.062, P=0.323) and FT3 (ß=-0.018, P=0.780) in SCH while levels increased with elevated total cholesterol (ß=0.229, P=0.001), LDL (ß=0.203, P=0.009) and triglycerides (ß=0.159, P=0.036) after adjustment for ageand body mass index. T-AOC reduced (ß=-0.327, P=0.030) with increased MDA in euthyroid controls and not in SCH (ß=-0.068, P=0.349), while levels increased with elevated triglycerides in both groups. Conclusion: Oxidative stress was increased in subclinical hypothyroidism as evidenced by the elevated lipid peroxidation product, malondialdehyde, while protein oxidation was absent. Thus, reduction of oxidative stress may be beneficial in patients with subclinical hypothyroidism. [ABSTRACT FROM AUTHOR]
