RESUMEN
Background: Endometrial cancer (EC) is a kind of common gynecological tumor. Further study on the markers related to the prognosis of endometrial cancer is important for women worldwide. Methods: The Cancer Genome Atlas (TCGA) database was used to obtain the transcriptome profiling and clinical data. A model was built using packages based on R software. Immune-related databases were employed to analyze the infiltration of immunocytes. Quantitative real-time PCR (qRT-PCR), cell counting kit-8 (CCK-8), and transwell assays were utilized to investigate the role of CFAP58-DT in EC. Results: Following Cox regression analysis, 1,731 ferroptosis-related long non-coding RNA (lncRNA) were screened, and a 9-related lncRNA prognostic model was constructed. Patients were classified as high- and low-risk according to their expression spectrum. Kaplan-Meier (KM) analysis showed that the prognosis of low-risk patients was poor. Operating characteristic curves, decision curve analysis, and a nomogram suggested the model could independently guide prognostic evaluation, with higher sensitivity, specificity, and efficiency than other common clinical characteristics. Gene Set Enrichment Analysis (GSEA) was conducted to determine the enriched pathways among the two groups and evaluation of the immune-inï¬ltrating conditions were performed to help improve immune therapy. Finally, we conducted cytological studies on the model's most important indicators. Conclusions: Overall, we identified a prognostic ferroptosis-related lncRNA model based on CFAP58-DT for predicting the prognosis and immune-inï¬ltrating conditions in EC. We concluded that the potential oncogenic role of CFAP58-DT can further guide immunotherapy and chemotherapy.
RESUMEN
The objective of this study was to systemically and comprehensively evaluate the associations between smoking and disease outcomes in patients with ankylosing spondylitis (AS). Information on smoking, clinical features, and sociodemographic characteristics was collected by a questionnaire administered directly to the patient. Group differences were analyzed by t test or chi-square test. Logistic regression analysis was conducted with the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), C-reactive protein, and erythrocyte sedimentation rate as the dependent variables and different stratification of smoking duration, smoking intensity, and cumulative smoking as independent variables. In order to compare our results with previous studies, meta-analysis was performed to calculate standardized mean difference (SMD) for relationship between outcomes and smoking status. A total of 1178 AS patients were analyzed. Compared with non-smokers, the risk of having active disease (BASDAI ≥ 4) was higher in patients who smoked at least 15 years, or 15 cigarettes per day, or 15 pack-years (OR = 1.70 [1.06, 2.73], 1.75 [1.08, 2.82], and 1.97 [1.06, 3.67], respectively); and smokers had increasing risk of BASDAI ≥ 4 with increasing years of smoking, or cigarettes per day, or pack-years (p-trend = 0.010, 0.008 and 0.006, respectively). The risk of having active disease was higher in patients who smoked at least 15 cigarettes per day or 15 pack-years (OR = 1.74 [1.06, 2.84] and 2.89 [1.56, 5.35], respectively), with increasing number of cigarettes per day and pack-years. Smokers had an increased risk of BASFI ≥ 4 (p-trend = 0.040 and 0.007, respectively). By meta-analysis, current, former and ever smokers had significantly higher BASDAI (SMD = 0.34 [0.18, 0.48], 0.10 [0.01, 0.19], and 0.27 [0.20, 0.34], respectively) and BASFI (SMD = 0.35 [0.16, 0.55], 0.30 [0.22, 0.39], and 0.35 [0.21, 0.50], respectively) compared to non-smokers. Smoking is a risk factor for greater disease activity and worse functioning in AS patients.

AIM: A Mendelian randomization study (MRS) can be linked to a "natural" randomized controlled trial in order to avoid potential bias of observational epidemiology. We aimed to study the possible association between serum urate (SU) and total bilirubin (TBIL) using MRS. MATERIALS AND METHODS: An observational epidemiological study using ordinary least squares (OLS) regression and MRS using two-stage least square (TLS) regression was conducted to assess the effect of SU on TBIL. The comparison between the OLS regression and the TLS regression was analyzed by the Durbin-Hausman test. If the p value is significant, it suggests that the OLS regression cannot evaluate the relationship between exposure and outcome, and the TLS regression is precise; while if the p value is not significant, there would be no significant difference between the two regressions. RESULTS: A total of 3,753 subjects were analyzed. In OLS regression, there was no significant association between SU and TBIL in all subjects and subgroup analysis (all p > 0.05). However, MRS revealed a negative correlation between SU and TBIL after adjustment for confounders (beta = -0.021, p = 0.010). Further analysis was conducted in different SU subgroups, and results show that elevated SU was associated with a significant reduction in TBIL after adjustment for hyperuricemic subjects (beta = -0.053, p = 0.027). In addition, the results using the Durbin-Hausman test further confirmed a negative effect of SU on TBIL (p = 0.002 and 0.010, respectively). CONCLUSIONS: This research shows for the first time that elevated SU was a potential causal factor in the reduction of TBIL and it provides strong evidence to resolve the controversial association between SU and TBIL.
RESUMEN
PURPOSE: High levels of serum uric acid can predict the progression of stage I and II chronic kidney disease (CKD), but whether serum urate is an independent risk factor or has causal impact on serum creatinine (SCr) and renal function remains unclear. METHODS: Mendelian randomization was used to determine whether serum uric acid had a causal effect on renal function, represented by estimated glomerular filtration rate (eGFR), with potential confounding factors, in 3734 subjects from the Taizhou Longitudinal Study. In the two-stage least squares method of Mendelian randomization, serum uric acid level was selected as the exposure, genetic risk score of uric acid transporters was selected as the instrumental variable, and SCr and eGFR were selected as the outcomes. RESULTS: The result of the analysis showed that increased serum uric acid was not a causal effect on renal function, but it was a causal effect on reducing estimated glomerular filtration rate in both the female population and the subjects who were under 65 years old. We also found that increased serum uric acid levels led to impaired renal function only in the subjects with normal eGFR values. In addition, the serum uric acid was a risk factor for renal function in the subjects with relatively high levels of fasting glucose or who were currently smokers. CONCLUSIONS: Although serum urate is not an independent risk factor for renal dysfunction, it has a causal effect on renal dysfunction in either female or individuals of under 65, or normal eGFR, or high level of fasting glucose, or current smokers.

The study aimed to determine whether unique clinical patterns of AS may exist in China, specifically to explore the different clinical manifestations caused by gender, HLA-B27 status, and age at disease onset. The multicenter cross-sectional survey was conducted and 1251 patients were enrolled across China, representing a broad spectrum of Chinese AS patients. The mean age at onset and diagnosis were 29.2 (11.4) and 33.5 (12.6) years, respectively. The male/female ratio was 2.7:1. Acute anterior uveitis (AAU) was experienced in 10.3% of AS patients and 9.1% patients had juvenile-onset AS (JoAS). Men were significantly younger at onset and diagnosis and showed a higher frequency of HLA-B27 positivity, JoAS, and AAU than women. HLA-B27-positive patients had a younger age of onset than HLA-B27-negative patients. HLA-B27-positive patients were nearly three times as likely to develop AAU than negative patients (P = 0.04). JoAS patients had a family history of AS more often than adult-onset AS (AoAS) patients, and 4.9% of JoAS patients underwent surgical treatments, a rate more than six times that of AoAS patients (P = 0.01). Men had higher levels of C-reactive protein than women, as did HLA-B27 positives compared to negative patients, and JoAS compared to AoAS (all P < 0.05). The clinical patterns of our AS patients were similar to those in other studies in non-Chinese cohort: (1) the age at onset was 29.2 (11.4) years, which was older than found in other studies; (2) men were more likely be HLA-B27 carriers than women; and (3) AAU was less common in Chinese patients.

Gout is a common inflammation disease resulting from an increase in serum uric acid. Nearly 70% of uric acid is excreted via the kidneys. To date, evidence for an association between genetic loci and gout is absent, equivocal or not replicated. Our study aims to test variants in two genes abundantly expressed in the kidney, LRP2 and COMT, for their association with uric acid and gout. In total, 1318 Chinese individuals were genotyped for rs2544390 in LRP2 and rs4680 in COMT. These LRP2 and COMT gene polymorphisms showed no significant effect on uric acid (P = 0.204 and 0.188, separately); however, rs2544390 in LRP2 did influence uric acid levels in individuals with BMI ≥ 25 (P = 0.009). In addition, the allele frequency distributions of the two loci showed a significant difference between gout patients and healthy controls. A missense variation in rs4680 (G > A) decreased the risk of gout (OR = 0.77, P = 0.015), whereas the T allele of rs2544390 was associated with gout pathogenesis risk (OR = 1.26, P = 0.020). The present study provides the first evidence for an association between COMT and gout. Rs2544390 in LRP2 only influenced uric acid levels in individuals with BMI ≥ 25, which might explain the discrepant results among previous studies. In addition, we are the first to identify the association between LRP2 and gout in a Chinese population and to confirm this association in Asians.

OBJECTIVE: To investigate the prevalence and influencing factors related to abuse and negligence against the elderly in the rural areas. METHODS: 975 elderly over 60 years from 41 counties in Anhui province were included. All participants completed an anonymous questionnaire including items as: educational background, marital condition, income, child-discipline, rude action to parents, daily activities, physical functions, having chronic illness, abuse and negligence against the elderly, etc. RESULTS: In the last year, rates of common physical abuse, serious physical abuse, emotional abuse, financial exploitation, negligence, overall abuse and negligence against the elderly were 4.5%, 1.5%, 26.9%, 4.9%, 7.2%, 29.9% respectively. Among the 281 victims, 80.4% reported that they were suffered more than 3 times of abuse and neglect episodes, and 34.9% reported that they were suffered more than 2 forms of abuse and negligence. The primary sadism was carried out by the daughter-in-law or son-in-law (43.2%) of the elderly. Low activity on daily life and having chronic illness were the risk factors causing common physical abuse while better education was the protective factor to it. Low ability in managing daily activity of living was the risk factor causing serious physical abuse. Less active on daily life and having rude action to parents were the risk factors to emotional abuse, but being strict with their children was the protective factor to emotional abuse. Less active on daily life, often beating their children and having rude action to parents were the risk factors related to financial exploitation. Less active on daily life, having rude action to parents and having bad physical functions were the risk factors causing negligence. Less active on daily life and having rude manner to parents were the risk factors of overall elderly abuse and negligence, but being strict with their children was protective factor to the abuse and negligence against the elderly. CONCLUSION: High prevalence on abuse and negligence against the elderly was seen in the rural areas of China. Different forms on elderly abuse and negligence were affected by different factors that called for more attention to be paid to those elderly with lower ability in managing their daily life.
