BACKGROUND
Metabolic syndrome (MetS) is a global health concern, and it is particularly harmful to middle-aged and elderly individuals. Life Element Eight (LE8), a measure to improve cardiovascular health, may offer benefits for MetS. Herein, we examined the relationship between LE8 and MetS among middle-aged and elderly individuals, and elucidated the role of biological aging and inflammation in this process.
METHODS
We obtained the LE8 scores of 2,901 Americans, along with their biological aging indicators (Biological age, Phenotypic age, Serum Klotho), and computed their inflammatory indicators SII, DII. Using logistic regression model, we assessed the association among inflammatory markers, Biological aging, LE8 and MetS. Additionally, we generated restricted cubic spline (RCS) plots to display trends in significant variables in logistic regression. Using parallel mediation analysis, we evaluated the possible mediating role of various factors in the risk relationship between LE8 and MetS.
RESULTS
Our examination revealed that higher LE8 scores were associated with a lower incidence of MetS in a fully adjusted model. The high LE8 subgroup had a 79.73% reduction in the risk of MetS compared to the low subgroup with an OR = 0.2027 (95% Cl 0.0871, 0.4714), with similar correlations between health factor scores and MetS risk. Biological aging mediated the associations between LE8, health behaviors and health factor scores and MetS risk.
CONCLUSION
A rise in the LE8 score among middle-aged and elderly individuals is a protective factor for MetS, and this association may be partially mediated by biological aging, suggesting that LE8 may reduce the risk of MetS by ameliorating aging.

Previous research has suggested that dyslipidemia may be a risk factor for rotator cuff syndrome (RCS), and lipid-lowering drugs may aid in its treatment, though conclusions have not been definitive. Mendelian randomization is a statistical method that explores the causal relationships between exposure factors and diseases. It overcomes the confounding issues inherent in traditional observational studies, thereby providing more reliable causal inferences. We employed this method to investigate whether hyperlipidemia is a risk factor for rotator cuff syndrome and whether lipid-lowering drugs can effectively treat this condition. Genetic variations linked to lipid traits low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and total cholesterol (TC) were acquired from the UK Biobank and the Global Lipids Genetics Consortium (GLGC). Data on genetic variation in rotator cuff syndrome were obtained from FinnGen, including 24,061 patients and 275,212 controls. In the next step, we carried out two-sample Mendelian randomization analyses to determine whether lipid traits correlate with rotator cuff syndrome risk. Additionally, we performed drug-target Mendelian randomization (MR) analyses on 10 drug targets related to rotator cuff syndrome. For the drug targets that showed significant results, further analysis was done using Summary-data-based Mendelian Randomization (SMR) and colocalization techniques. We performed a mediation analysis to identify potential mediators between HMG-CoA reductase (HMGCR) and RCS. No causative link was established between these lipid traits and rotator cuff syndrome. However, a significant association has been identified where HMGCR inhibition corresponds to a reduced risk of rotator cuff disease (OR = 0.68, [95% CI, 0.56-0.83], = 1.510 × 10). Additionally, enhanced expression of HMGCR in muscle tissues is also linked to a decreased risk of rotator cuff syndrome (OR = 0.88, [95% CI, 0.76-0.99], = 0.03). Body mass index (BMI) mediated 22.97% of the total effect of HMGCR on RCS. This study does not support low-density LDL-C, TG, and TC as risk factors for rotator cuff syndrome. HMGCR represents a potential pharmaceutical target for preventing and treating rotator cuff syndrome. The protective action of statins on the rotator cuff syndrome might not be associated with their lipid-lowering properties.

Review
The lung is an important site of extramedullary platelet formation, and megakaryocytes in the lung participate in immune responses in addition to platelet production. In acute lung injury and chronic lung injury, megakaryocytes and platelets play a promoting or protective role through different mechanisms. The authors reviewed the role of megakaryocytes and platelets in common clinical lung injuries with different course of disease and different pathogenic factors in order to provide new thinking for the diagnosis and treatment of lung injuries.

Autoimmunity Dec 2024Rheumatoid arthritis (RA) is a chronic autoimmune disease, and understanding its genetic and molecular basis is crucial for early diagnosis, treatment, and prevention.
BACKGROUND
Rheumatoid arthritis (RA) is a chronic autoimmune disease, and understanding its genetic and molecular basis is crucial for early diagnosis, treatment, and prevention.
OBJECTIVE
This study aims to explore the association between polymorphisms (rs2227284, rs2243267, rs2243270, and rs2243283) and RA risk.
METHODS
The four polymorphisms were genotyped in 493 RA patients and 493 healthy controls using Agena MassARRAY. Logistic regression analysis calculated odds ratio (OR) and 95% confidence interval (CI) to estimate the relationship between polymorphisms and RA risk.
RESULTS
Overall analysis revealed that rs2243267 (GG vs. CC: OR = 0.26, FDR- = .032; Recessive: OR = 0.27, FDR- = .048) and rs2243270 (AA vs. GG: OR = 0.26, FDR- = .024; Recessive: OR = 0.27, FDR- = .024) were associated with a decreased risk of RA. Stratified analysis indicated that rs2243267 and rs2243270 were correlated with reduced RA risk in female, smoking, BMI <24, and drinking population; rs2227284 was associated with a decreased RA risk in BMI <24 and drinking population. Moreover, rs2243267 and rs2243270 were significantly associated with reduced ACPA positivity.
CONCLUSIONS
Our findings suggest that polymorphisms (rs2227284, rs2243267, and rs2243270) act as protective factors for RA in the Chinese Han population.

BACKGROUND
Investigating novel therapeutic strategies for colorectal cancer (CRC) is imperative. However, there is limited research on the use of drugs to target peripheral blood immune cells in this context. To address this gap, we performed a two-sample Mendelian randomization (MR) analysis to identify potential therapeutic targets for CRC.
METHODS
We applied two-sample MR to identify the causal relationship between peripheral blood immune cells and CRC. GWAS data were obtained from the IEU OPEN GWAS project. Based on the implications from the MR results, we conducted a comprehensive database search and genetic analysis to explore potential underlying mechanisms. We predicted miRNAs for each gene and employed extensive research for potential therapeutic applications.
RESULTS
We have identified causal associations between two peripheral immune cells and colorectal cancer. Activated & resting Treg %CD4 + cell was positively associated with the risks of CRC, while DN (CD4-CD8-) %leukocyte cell exhibited a protective role in tumor progression. NEK7 (NIMA related kinase 7) and LHX9 (LIM homeobox 9) expressed in Treg cells were positively associated with CRC risks and may play a vital role in carcinogenesis.
CONCLUSIONS
This study identified causal relationship between peripheral immune cell and CRC. Treg and DN T cells were implicated to own promoting and inhibiting effects on CRC progression respectively. NEK7 and LHX9 in Treg cells were identified as potential biotarget for antitumor therapies.

BACKGROUND
Civilian war and internal conflicts increase the incidences of mental health conditions among war survivors. It is crucial to assess war-related psychological consequences in war-affected areas in Ethiopia to intervene in the future. Thus, this study aimed to determine the magnitude of psychological distress and associated factors of psychological distress among war survivor women in Northern, Ethiopia.
METHODS
A community-based cross-sectional survey was conducted, and 1596 war survivor women were recruited to participate using a face-to-face interviews with a census sampling technique from May 1-30, 2022. The psychological distress was assessed using a Kessler psychological distress scale (K10). Bi-variable and multi-variable logistic regression analyses were used, and variables with a p-value less than 0.05 in the multivariable analyses were considered statistically significant.
RESULT
In this study, the response rate was 100% and the prevalence of psychological distress was 44.90% at a 95% CI: (42.40, 47.40). Psychological distress was significantly associated with the education of ability to read and write (AOR = 2.92; 95% CI: 2.12, 4.01), primary education and above (AOR = 3.08; 95% CI: 2.09, 4.54), housewife (AOR = 5.07; 95%CI: 2.64, 9.74), farmer (AOR = 8.92; 95%CI: 4.03, 19.70), emotional violence (AOR = 1.52; 95%CI: 1.05, 2.18), physical violence (AOR = 3.85; 95%CI: 2.37, 6.26) and sexual violence (AOR = 3.25; 95%CI: 1.98, 5.33) whereas being separate was protective for psychological distress (AOR = 0.38; 95%CI: 0.16, 0.92).
CONCLUSION
The prevalence of psychological distress was found to be high. Therefore, women who are housewives, married, farmers, educated, and who have experienced violence must be the focus of governmental and private collaborative interventions to prevent war-related psychological morbidity and mortality.

BACKGROUND
Smoking cessation is a dynamic process that often involves a series of unsuccessful quit attempts before long-term abstinence is achieved. To implement interventions that lead to long-term abstinence, it will be necessary to understand the determinants of smoking cessation. Therefore, the main objective of the present study was to determine the effect of factors influencing both smoking cessation attempts and successful smoking cessation in the general population of Iran.
METHODS
The data of 1293 participants whose information was obtained through a national cross-sectional study entitled "Survey of Risk Factors of Noncommunicable Diseases in 2016" were analyzed. There were three response levels: "quit attempt and successful quit", "quit attempt and unsuccessful quit", and "no quit attempt and unsuccessful quit". A multinomial logistic regression model was used to assess the effect of covariates on response.
RESULTS
The mean (sd) age of all participants was 47.21 (13.65) years. According to the results, 883 people (68.29%) did not attempt to quit smoking, and of those who attempted to quit smoking, only 64 (15.61%) men were successful. The factors of living in an urban area (OR = 1.71) and past smoking intensity (OR = 1.967) were associated with no quit attempt and unsuccessful quitting. In addition, physician recommendation to quit smoking was a protective factor for no quit attempt and unsuccessful quit (OR = 0.599). Alcohol consumption was also a protective factor against successful quitting for both attempters (OR = 0.351) and nonattempters (OR = 0.359).
CONCLUSIONS
Tobacco control programs should be implemented with a greater focus on heavy smokers and alcohol users. In addition, the role of health professionals in encouraging smokers to quit smoking should not be ignored.

BACKGROUND
Rheumatoid arthritis (RA) is a chronic immune system disease with a high disability rate threatening the living quality of patients. Identifying potential biomarkers for RA is of necessity to improve the prevention and management of RA.
OBJECTIVES
This study focused on miR-146b-3p evaluating its clinical significance and revealing the underlying regulatory mechanisms.
MATERIALS AND METHODS
A total of 107 RA patients were enrolled, and both serum and synovial tissues were collected. Another 78 osteoarthritis patients (OA, providing synovial tissues), and 72 healthy individuals (providing serum samples) were enrolled as the control group. The expression of miR-146b-3p was analyzed by PCR and analyzed with ROC and Pearson correlation analyses evaluating its significance in diagnosis and development prediction of RA patients. In vitro, MH7A cells were treated with TNF-α. The regulation of cell proliferation, motility, and inflammation by miR-146b-3p was assessed by CCK8, Transwell, and ELISA assays.
RESULTS
Significant upregulation of miR-146b-3p was observed in serum and synovial tissues of RA patients, which distinguished RA patients and were positively correlated with the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anti-cyclic citrullinated peptide antibodies (anti-CCP), and rheumatoid factor (RF) of RA patients. TNF-α promoted the proliferation and motility of MH7A cells and induced significant inflammation in cells. Silencing miR-146b-3p alleviated the effect of TNF-α and negatively regulated the expression of HMGCR. The knockdown of HMGCR reversed the protective effect of miR-146b-3p silencing on TNF-α-stimulated MH7A cells.
CONCLUSIONS
Increased miR-146b-3p served as a biomarker for the diagnosis and severity of RA. Silencing miR-146b-3p could suppress TNF-α-induced excessive proliferation, motility, and inflammation via regulating HMGCR in MH7A cells.

Patients with immune-mediated inflammatory diseases are prone to steatotic liver disease (SLD), which has been observed in patients with psoriasis and hidradenitis suppurativa. We aimed to assess whether systemic lupus erythematosus (SLE) was associated with SLD and to define factors associated with SLD in SLE. This was a cross-sectional study, we included 106 consecutive patients with SLE who were seen in the rheumatology clinic between June 2021 and March 2022 and we chose two sex-paired controls for each SLE. All the participants underwent FibroScan and anthropometric assessments. SLD was defined as a controlled attenuation parameter ≥ 275dB/m. Prevalence of SLD was lower in patients with SLE (21.7% vs 41.5%, p < 0.001). Patients with SLE and SLD had a lower frequency of hydroxychloroquine use (65% vs 84%, p = 0.04), and higher C3 levels [123mg/dl (IQR 102-136) vs 99mg/dl (IQR 78-121), p = 0.004]. Factors associated with SLD in SLE were body mass index (BMI), waist circumference, glucose, and C3; hydroxychloroquine use was a protective factor. On univariate analysis, SLE was associated with a reduced risk of SLD (OR 0.39, 95%CI 0.23-0.67); however, after adjusting for age, BMI, waist, glucose, triglycerides, high-density cholesterol, low-density cholesterol, leukocytes, and hydroxychloroquine, it was no longer associated (OR 0.43, 95%CI 0.10-1.91). In conclusion, the prevalence of SLD in patients with SLE was not higher than that in the general population, and SLE was not associated with SLD. The factors associated with SLD were anthropometric data, glucose, hydroxychloroquine, and C3 levels.

Butorphanol is widely used as an anesthetic drug, whether butorphanol could reduce organ injury and protecting lung tissue is unknown. This study explored the effects of butorphanol on ALI and investigated its underlying mechanisms. We established a "two-hit" rat model and "two-hit" cell model to prove our hypothesis. Rats were divided into four groups [control, "two-hit" (OA + LPS), "two-hit" + butorphanol (4 mg/kg and 8 mg/kg) (OA + LPS + B1 and OA + LPS + B2)]. RPMVE cells were divided into four groups [control, "two-hit" (OA + LPS), "two-hit" + butorphanol (4 μM and 8 μM) (OA + LPS + 4 μM and OA + LPS + 8 μM)]. Inflammatory injury was assessed by the histopathology and W/D ratio, inflammatory cytokines, and arterial blood gas analysis. Apoptosis was assessed by Western blotting and flow cytometry. The effect of NF-κB p65 was detected by ELISA. Butorphanol could relieve the "two-hit" induced lung injury, the expression of TNF, IL-1β, IL-6, and improve lung ventilation. In addition, butorphanol decreased Bax and cleaved caspase-3, increased an antiapoptotic protein (Bcl-2), and inhibited the "two-hit" cell apoptosis ratio. Moreover, butorphanol suppressed NF-κB p65 activity in rat lung injury. Our research showed that butorphanol may attenuate "two-hit"-induced lung injury by regulating the activity of NF-κB p65, which may supply more evidence for ALI treatment.
