RESUMO
Despite the robust correlation between metabolic disorders and heavy metals, there has been limited research on the associations between nickel levels and non-alcoholic fatty liver disease (NAFLD) as well as liver fibrosis. This study aimed to examine the associations among urinary nickel, NAFLD, and liver fibrosis. The data utilized in this study were obtained from the National Health and Nutrition Examination Survey 2017-2020. A comprehensive screening process was conducted, resulting in the inclusion of a total of 3169 American adults in the analysis. The measurement of urinary nickel was conducted through inductively coupled-plasma mass spectrometry. Vibration-controlled transient elastography was employed to assess the controlled attenuation parameter and liver stiffness measurement as indicators for NAFLD and liver fibrosis, respectively. Multivariable logistic regression models were employed to evaluate the associations among urinary nickel, NAFLD, and liver fibrosis. Restricted cubic splines were employed to explored the nonlinear associations. After adjusting for all covariates, the correlation between the highest quartile of urinary nickel and NAFLD was found to be significant (OR = 1.65; 95% CI, 1.19-2.27). Subgroup analysis revealed that the correlation was significant only in men. A significant association occurred between the second quartile of urinary nickel and liver fibrosis (OR 1.88; 95% CI, 1.22-2.90). Restricted cubic spline showed that the relationship was linear between urinary nickel and NAFLD and non-monotonic, inverse U-shaped between urinary nickel and liver fibrosis. This cross-sectional study indicated that the risk of NAFLD is associated with urinary nickel, and this correlation was only present among males.
RESUMO
Background: Immunotherapy has provided a novel therapeutic option for lung cancer but studies involving patients with advanced non-small cell lung cancer (NSCLC) coupled with various degrees of comorbid chronic obstructive pulmonary disease (COPD) are limited. Thus, we performed a retrospective cohort study to optimize the use of immunotherapy in this special population. Methods: We enrolled a total of 99 patients with advanced (stage IIIB/C-IV) NSCLC with comorbid COPD who had received immune checkpoint inhibitors (ICIs) according to the inclusion and exclusion criteria. They were divided into four groups according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guideline criteria as follows: no COPD group (n1=19), mild COPD group (n2=24), moderate COPD group (n3=31), and severe COPD group (n4=25). Routine blood, imaging characteristics, related cytokines including interleukin (IL)-6, IL-8, IL-10, etc., Krebs Von den Lungen (KL)-6, and corresponding indicators of immune-related adverse events (irAEs), incidence of irAEs, objective response rate (ORR), disease control rate (DCR) and progression-free survival (PFS) were recorded and analyzed. Comparability of baseline factors above and clinical characteristics were evaluated. Results: There were statistically significant differences in the incidence of irAEs among the four groups (P=0.003). The incidence of irAEs in patients with no COPD (n1, 21.1%) and mild to moderate COPD (n2/3, 8.3%, 32.3%) was lower than that in patients with severe COPD (n4, 56.0%) (P=0.003). The median PFS of the mild to moderate COPD group was significantly longer than the severe COPD group (19.0 vs. 8.00 months, log-rank P=0.004). A significant increase of both ORR (P=0.004) and DCR (P=0.037), as well as higher IL-6 (P=0.000), IL-8 (P=0.026), and IL-10 (P=0.010) levels, have been observed in the mild to moderate COPD group compared with severe COPD group. IL-6 level was an independent factor influencing PFS [P=0.007, 95% confidence interval (95% CI): 1.000-1.002] and COPD grading was an independent predictor of irAEs (P=0.037, 95% CI: 1.035-3.039). Conclusions: Immunotherapy should be selected with caution for advanced NSCLC patients with comorbid severe COPD, considering the limited efficacy and the increased risk of immune-related adverse events related to the immune-checkpoint inhibitors administration in this special population.
RESUMO
Depressive symptoms are major public health problems. Leisure-time Physical activity (LPA) and dietary inflammatory preference are emerging factors that tends to affect the mental health status. There is limited evidence regarding the joint influence of LPA and dietary status on the prevalence of depression. This study was a cross-sectional study, which used a nationwide represented sample from the National Health and Nutrition Examination Survey (NHANES) to assess the relationship among LPA, diet status and depression. Depression and LPA status was reported by the 9-item Patient Health Questionnaire (PHQ-9) and Physical Activity Questionnaire (PAQ), respectively. To assess dietary inflammatory preferences, dietary inflammatory index (DII) was applied based on a 24-h dietary recall interview. A total of 11,078 subjects was included in this study and weighted participants were 89,682,020. Weighted multivariable linear regression showed that DII was negatively associated with LPA after full adjustment, with ß (95% CI): -0.487 (-0.647, -0.327). Weighted multivariable logistic regression showed that LPA was significantly associated with depressive symptoms after full adjustment, with odds ratios OR (95% CIs): 0.986 (0.977, 0.995). By DII stratification analysis, this phenomenon was also existed in groups with anti-inflammatory diet. Mediation effect analysis was further performed, which showed that DII significantly mediating the association between LPA and depression with proportion mediated as 3.94%. Our findings indicated the mediating role of DII in the association between LPA condition and incident depression. More well-designed studies are still needed to validate the causal relationship.
RESUMO
BACKGROUND: Patients with non-small cell lung cancer (NSCLC) complicated with chronic obstructive pulmonary disease (COPD) with poor performance status (PS) are common in clinical practice with few related studies. Present studies have found that weekly low-dose docetaxel or gemcitabine combined with platinum is suitable for elderly or poor PS patients with advanced NSCLC. METHODS: Untreated advanced driver mutation-negative NSCLC patients with COPD and PS ≥2 were enrolled in this double-blind randomized trial. Both groups controlled their COPD symptoms according to the GOLD guidelines. The anti-tumor regimens included docetaxel (37.5 mg/m2, D1, D8)/carboplatin (AUC 5.0) (DC group) and gemcitabine (1,000 mg/m2, D1, D8)/carboplatin (AUC 5.0) (GC group) were used every 3 weeks with continuous chemotherapy for 4-6 cycles or until disease progression. The primary endpoints were progression-free survival (PFS), and overall survival (OS). RESULTS: Among the 52 patients (DC, n=25; GC, n=27), the median follow-up time was 12.3 months. There was no significant difference in tumor overall response rate (ORR; DC, 20.0% vs. GC, 22.2%, P=0.845) and disease control rate (DCR; DC, 72.0% vs. GC, 74.1%, P=0.064) between the 2 groups. The median PFS (GC, 6.5 vs. DC, 5.5 months; P=0.296) and the median OS (GC, 14.9 vs. DC, 12.3 months; P=0.548) of the GC group was slightly longer than the DC group. The main adverse reactions were myelosuppression and there were few adverse reactions of grade 3-4. Compared with the anti-tumor therapy only group in previous literature, the median PFS in this study was longer (6.2 months, 95% CI: 3.533-6.733 vs. 3.5 months, 95% CI: 2.432-4.568; P=0.589). There was also no significant difference in median OS and median PFS between the 2 groups (14.0 vs. 15.0 months, P=0.718). Chemotherapy cycle (P<0.001) was an independent prognostic factor for PFS, while chemotherapy cycle (P=0.011) and PS (P=0.041) were independent prognostic factors for OS. CONCLUSIONS: Weekly low-dose docetaxel or gemcitabine combined with carboplatin chemotherapy regimens can yield survival benefits and a tolerable safety profile in patients with driver mutation-negative advanced NSCLC and poor PS complicated with COPD, with no significant difference between the two regimens.
