ABSTRACT
INTRODUCTION: The bidirectional relationship between the brain cortex and cardiovascular diseases (CVDs) remains inadequately explored. METHODS: This study used bidirectional Mendelian randomization (MR) analysis to explore the interactions between nine phenotypes associated with hypertension, heart failure, atrial fibrillation (AF), and coronary heart disease (CHD), and brain cortex measurements. These measurements included total surface area (SA), average thickness (TH), and the SA and TH of 34 regions defined by the Desikan-Killiany atlas. The nine traits were obtained from sources such as the UK Biobank and FinnGen, etc., while MRI-derived traits of cortical structure were sourced from the ENIGMA Consortium. The primary estimate was obtained using the inverse-variance weighted approach. A false discovery rate adjustment was applied to the p-values (resulting in q-values) in the analyses of regional cortical structures. RESULTS: A total of 1,260 two-sample MR analyses were conducted. Existing CHD demonstrated an influence on the SA of the banks of the superior temporal sulcus (bankssts) (q=0.018) and the superior frontal lobe (q=0.018), while hypertension was associated with changes in the TH of the lateral occipital region (q=0.02). Regarding the effects of the brain cortex on CVD incidence, total SA was significantly associated with the risk of CHD. Additionally, 16 and 3 regions exhibited significant effects on blood pressure and AF risk, respectively (q<0.05). These regions were primarily located in the frontal, temporal, and cingulate areas, which are associated with cognitive function and mood regulation. CONCLUSION: The detection of cortical changes through MRI could aid in screening for potential neuropsychiatric disorders in individuals with established CVD. Moreover, abnormalities in cortical structure may predict future CVD risk, offering new insights for prevention and treatment strategies.
ABSTRACT
BACKGROUND AND AIMS: The novel sex-specific anthropometric equation relative fat mass (RFM) is a new estimator of whole-body fat %. The study aimed to investigate the predictive role of RFM in cardiometabolic abnormalities, cardiovascular disease (CVD), all-cause and cardiovascular mortality, and explored potential sex differences. METHODS AND RESULTS: The study analyzed data from 26,754 adults in NHANES 1999-2010, with a median follow-up of 13.8 years. The correlation between RFM and body composition as well as fat distribution assessed by dual-energy X-ray absorptiometry was investigated. Weighted multivariable generalized linear models, Cox proportional hazards models and restricted cubic spline were applied to investigate the predictive role of RFM in metabolic markers, cardiovascular risk factors, CVD, all-cause and cardiovascular mortality. RFM exhibited a robust correlation with both whole-body fat % and trunk fat %. Higher RFM exhibited a stronger association with impaired glucose homeostasis, serum lipids, the incidence of hypertension, and coronary heart disease in males, while a stronger association with C-reactive protein in females. A U-shaped association between RFM and all-cause mortality was observed only in males. The hazard ratio (HR) of all-cause and cardiovascular mortality in males increased rapidly when RFM exceeded 30. However, in females, the HR of all-cause and cardiovascular mortality fluctuated until RFM exceeded 45, after which it increased rapidly. CONCLUSION: RFM was a sex-specific estimator for both general and central obesity, sex-specific differences in predicting cardiometabolic abnormalities and adverse events using RFM might be partially attributed to differences in body composition and fat distribution between sexes.

BACKGROUND: To examine the safety and efficacy of ZelanteDVT™ catheter rheolytic thrombectomy in the treatment of patients with iliac vein stent thrombosis. METHODS: A retrospective analysis method was conducted by means of collecting the data of 32 patients who had completed the treatment of iliac vein stent thrombosis with ZelanteDVT catheter rheolytic thrombectomy from March 2019 to March 2023. Data on clinical characteristics, technical success, clinical success, complications, and early follow-up were analyzed. RESULTS: The technical success rates were 100%, intraoperatively, in which 22 cases were improved to thrombus clearance Grade II (50-90%), 10 were Grade III (>90%). There were 21 cases treated with subsequent catheter-directed thrombolysis, and the average urokinase administration of (120.90 ± 29.63)∗10Ë4 units. The clinical success rates were 100% and the swelling of the affected limbs were significantly improved, a significant difference in the pre/postoperative between-thigh circumference difference [(5.16 ± 1.08) vs. (1.75 ± 0.84), P < 0.000]. The pre/postoperative Venous Clinical Severity Score was [(12.94 ± 1.70) vs. (7.44 ± 1.31), P < 0.000]. No serious complications occurred during the perioperative period. The postoperative and 12-month stent patency rate was 100.00% (32/32) and 71.88% (23/32), respectively. CONCLUSIONS: The ZelanteDVT catheter rheolytic thrombectomy seems to have a promising application prospect for the treatment of patients with iliac vein stent thrombosis.

Objective: Plant-based diets have multiple health benefits for cancers; however, little is known about the association between plant-based dietary patterns and esophageal cancer (EC).This study presents an investigation of the prospective associations among three predefined indices of plant-based dietary patterns and the risk of EC. Methods: We performed endoscopic screening for 15,709 participants aged 40-69 years from two high-risk areas of China from January 2005 to December 2009 and followed the cohort until December 31, 2022. The overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI), were calculated using survey responses to assess dietary patterns. We applied Cox proportional hazard regression to estimate the multivariable hazard ratios (HRs) and 95% confidence intervals (95% CIs) of EC across 3 plant-based diet indices and further stratified the analysis by subgroups. Results: The final study sample included 15,184 participants in the cohort. During a follow-up of 219,365 person-years, 176 patients with EC were identified. When the highest quartile was compared with the lowest quartile, the pooled multivariable-adjusted HR of EC was 0.50 (95% CI, 0.32-0.77) for hPDI. In addition, the HR per 10-point increase in the hPDI score was 0.42 (95% CI, 0.27-0.66) for ECs. Conversely, uPDI was positively associated with the risk of EC, and the HR was 1.80 (95% CI, 1.16-2.82). The HR per 10-point increase in the uPDI score was 1.90 (95% CI, 1.26-2.88) for ECs. The associations between these scores and the risk of EC were consistent in most subgroups. These results remained robust in sensitivity analyses. Conclusions: A healthy plant-based dietary pattern was associated with a reduced risk of EC. Emphasizing the healthiness and quality of plant-based diets may be important for preventing the development of EC.
ABSTRACT
Background: The prognostic significance of QRS duration (QRSd) in patients with dilated cardiomyopathy (DCM) and a left ventricular ejection fraction (LVEF) between 30% and 50% is unclear, resulting in questions regarding eligibility for cardiac resynchronisation therapy. This study aimed to explore the prognostic role of QRSd in patients with DCM and a LVEF 30-50% or LVEF < 30. Methods: Patients hospitalised at Fuwai hospital with DCM who had a LVEF ≤ 50% were prospectively included. The primary outcomes were a composite of death, heart transplantation, and rehospitalisation for worsening heart failure. Results: Among the 633 patients included, 302 (47.7%) had a LVEF of 30-50%. The multivariable hazard ratio (HR) for QRSd ≥ 120 ms was 1.65 (95% confidence interval [CI] 1.29-2.11, p < 0.001) for overall DCM patients, 2.8 (95% CI 1.82-4.30, p < 0.001) for patients with LVEF 30-50%, and 1.41 (95% CI 1.02-1.94, p = 0.036) for patients with LVEF < 30%. QRSd ≥ 120 ms tended to be more strongly associated with outcome in patients with LVEF 30-50% than in those with LVEF < 30% despite the non-significant interaction (p = 0.067). DCM patients with QRSd ≥ 120 ms and LVEF 30-50% did not experience a significantly better outcome than those with LVEF < 30% and QRSd < 120 ms after propensity-score matching (HR 0.91, 95% CI 0.61-1.36, p = 0.645). Conclusions: QRSd independently predicts prognosis in DCM patients irrespective of LVEF and identifies a group of high-risk patients who may benefit from device implantation despite the absence of severely reduced LVEF.
ABSTRACT
Urbanization and globalization are changing the conventional constraints of seasonality and geography on food consumption, such as that of fresh cherries. The rising demand for year-round cherry consumption in China is currently satisfied by open-field, greenhouse-produced, and imported products. This study conducted a spatial-temporal life cycle evaluation of the environmental performance of cherry consumption behaviors during different seasons of the year. Moreover, based on the definitions of global and local seasonality, the additional environmental costs of out-of-season cherry consumption were estimated. Results show that seasonality was an important factor affecting the environmental burdens of cherry consumption. Eating cherries imported from Chile by air in October resulted in the highest greenhouse gas (GHG) emissions of 6.38 kg CO2-eq/kg, while eating domestic open-field cherries during May to July (the natural harvest season) was a relatively environmentally beneficial option. The total cherry consumption in China in 2019 generated GHG emissions of 126.99 × 104 t CO2-eq. Under the definitions of global and local seasonality, the out-of-season consumption led to additional environmental costs of 57.59 × 104 and 85.67 × 104 t CO2-eq, accounting for 45.35% and 67.46% of total emissions, respectively. Furthermore, the time-environment trade-off effect of cherry consumption illustrates the higher environmental costs are exchanged for satisfying the appetite for out-of-season fresh foods. Our findings emphasize the meaningful implications for developing a sustainable consumption pattern for all stakeholders involved in the entire food chain.

In our study, we aimed to assess the long-term risk of gastric cardia adenocarcinoma (GCA) for patients with different histological cardia lesions to inform future guidelines for GCA screening in China. We conducted a population-based prospective study among 9740 subjects who underwent upper endoscopy screening during 2005 to 2009 and followed until December 2017. Cumulative incidence and mortality rates of GCA were calculated by the baseline histological diagnoses, and the hazard ratios (HRs), overall and by age and sex, were analyzed by Cox proportional hazards models. During a median follow-up of 10 years, we identified 123 new GCA cases (1.26%) and 31 GCA deaths (0.32%). The age-standardized incidence and mortality rates of GCA were 128.71/100 000 and 35.69/100 000 person-years, and cumulative incidence rate in patients with cardia high-grade dysplasia (CHGD), cardia low-grade dysplasia (CLGD) and atrophic carditis (AC)/cardia intestinal metaplasia (CIM) was 25%, 3.05% and 1.58%, respectively. The progression rate and cancer risk of GCA increased monotonically with each step in Correa's cascade. Individuals aged 50 to 69 years had 4.4 times higher GCA incidence than those aged 40 to 49 years. Patients with CLGD had a significantly higher 3-year GCA incidence than the normal group, while patients with AC/CIM had a comparable GCA risk during 3-year follow-up but a higher risk at 5-year intervals. Our results suggested a postponed starting age of 50 years for GCA screening, immediate treatment for patients with CHGD, a 3-year surveillance interval for patients with CLGD, and a lengthened surveillance interval of 5 years for patients with AC/CIM.

OBJECTIVE: Research on generalized anxiety disorder (GAD) and its association with esophageal cancer (EC) is sparse. The study aimed to explore the association between GAD and EC. METHODS: A multicenter, population-based study in high-risk regions for EC (ECHRRs) was conducted from 2017 to 2019. All participants received free endoscopy screening. If the esophageal endoscopy results were suspicious, the pathological biopsy was performed to confirm normal, esophagitis, low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia (HGIN), and EC. Information on participants' exposure to risk factors was collected. GAD was assessed with Generalized Anxiety Disorder Scale-7. RESULTS: With esophageal endoscopy, 25,650 participants in ECHRRs were examined, 9586 of whom were suspicious and confirmed by esophageal pathology. The detection rate of EC and precancerous lesions was 6.83% (1751/25,650), with 1377 LGIN (5.37%), 272 HGIN (1.06%), and 102 EC (0.40%) cases. The overall mean GAD score (95% CI) and prevalence among 25,650 participants with endoscopy were 1.96 (1.93-1.99) and 16.90%, respectively. The mean GAD score and prevalence among 9586 participants with pathology were 1.96 (1.91-2.02) and 17.98%, respectively. The mean GAD scores of patients confirmed with normal, esophagitis, LGIN, HGIN, and EC were 1.73 (1.62-1.85), 1.91 (1.85-1.97), 1.94 (1.80-2.08), 3.98 (3.73-4.23). and 2.97 (2.49-3.45), respectively (p < 0.001). The corresponding prevalence of GAD were 5.21%, 18.72%, 17.72%, 43.75%, and 36.27%, respectively (p < 0.001). The age- and gender-adjusted odds ratios (ORs) between GAD and each esophageal lesion type were 1.02 (0.99-1.04), 1.01 (0.98-1.04), 1.27 (1.21-1.33), and 1.16 (1.08-1.24), respectively. The ORs (95% CIs) of the positive associations were 1.08 (1.05-1.12), 1.03 (0.99-1.07), 1.35 (1.29-1.42), and 1.19 (1.10-1.29) after further adjustment for potential confounders (all p < 0.001). Sensitivity analysis showed that the positive association persisted. CONCLUSIONS: GAD was significantly higher in patients with EC and precancerous lesions. Focusing on and alleviating anxiety in high-risk groups (including patients with HGIN and EC) may be an effective strategy for EC prevention and control. Further prospective studies are warranted to validate the results.

BACKGROUND: Esophageal cancer (EC) is one of the leading contributors to the global burden of cancer, and the underlying mechanism is still unknown. Recently, there has been a growing interest in understanding modifiable psychosocial risk factors, particularly depression, to prevent EC and reduce morbidity and mortality. However, related research is sparse and has been ignored. The study was designed to assess the association between depression and EC in China. METHODS: From 2017 to 2019, a population-based multicenter study was conducted in high-risk regions of EC. Participants underwent a free endoscopy screening. If the endoscopic results were suspicious, a pathological biopsy was applied to confirm. Depression was measured with Patient Health Questionnaire-9 (PHQ-9). In addition, information on demographic characteristics and risk factors was collected from participants by trained interviewers using uniform questionnaires. RESULTS: After Endoscopy and pathologic diagnosis, 15,936 participants in high-risk regions of EC (ECHRRs) were enrolled, 10,907 (68.44%) of which were diagnosed health, 4048 (25.40%) with esophagitis, 769 (4.83%) with low-grade intraepithelial neoplasia (LGIN), 157 (0.99%) with high-grade intraepithelial neoplasia (HGIN), and 55 (0.35%) with EC, respectively. The overall prevalence of depression symptoms of participants was 4.16% (health: 4.63%, esophagitis: 2.99%, LGIN: 2.99%, HGIN: 5.73%, and EC: 9.09%). Multiple logistic regression analyses revealed that the unadjusted OR (95% CI) between depression and each esophageal pathology grades were esophagitis 0.93 (0.92-0.95), LGIN 0.97 (0.94-0.99), HGIN 1.05 (1.00-1.10), and EC 1.04 (0.97-1.14), respectively. However, after adjustment for potential confounders (age, gender, region, alcohol consumption, BMI), no statistically significant associations between depression and EC (adjusted OR = 1.10, 0.99-1.21) and esophageal lesions (esophagitis: adjusted OR = 1.02, 0.99-1.04; LGIN: adjusted OR = 0.98, 0.95-1.01; HGIN: adjusted OR = 1.04, 0.98-1.11) were observed in this study. CONCLUSIONS: No significant association was observed between depression and EC in the study. Future prospective cohort studies are needed to verify this preliminary finding.

INTRODUCTION: Data on the associations between esophageal histological lesions and risk of esophageal squamous cell carcinoma (ESCC) in general populations are limited. We aimed to investigate these associations in a large Chinese general population to inform future Chinese ESCC screening guidelines. METHODS: We performed endoscopic screening of 21,111 participants aged 40-69 years from 3 high-risk areas of China in 2005-2009, and followed the cohort through 2016. Cumulative incidence and mortality rates of ESCC were calculated by baseline histological diagnosis, and hazard ratios of ESCC, overall and by age and sex, were assessed using the Cox proportional hazards models. RESULTS: We identified 143 new ESCC cases (0.68%) and 62 ESCC deaths (0.29%) during a median follow-up of 8.5 years. Increasing grades of squamous dysplasia were associated with the increasing risk of ESCC incidence and mortality. The cumulative ESCC incidence rates for severe dysplasia/carcinoma in situ, moderate dysplasia (MD), and mild dysplasia were 15.5%, 4.5%, and 1.4%, respectively. Older individuals (50-69 years) had 3.1 times higher ESCC incidence than younger individuals (40-49 years), and men had 2.4 times higher ESCC incidence than women. DISCUSSION: This study confirmed that increasing grades of squamous dysplasia are associated with increasing risk of ESCC and that severe dysplasia and carcinoma in situ require clinical treatment. This study suggests that in high-risk areas of China, patients with endoscopically worrisome MD should also receive therapy, the first screening can be postponed to 50 years, and endoscopic surveillance intervals for unremarkable MD and mild dysplasia can be lengthened to 3 and 5 years, respectively.

BACKGROUND AND AIM: This study aimed to evaluate effects of endoscopic screening method in different starting age groups and further confirm the optimum starting age for esophageal squamous cell cancer (ESCC) screening. METHODS: This study received institutional review board approval, and 6825 residents aged 40 to 69 years in high prevalence communities were assigned to the screening group or the control (non-screening) group from Hebei, China. Cumulative mortalities during the 14-year period, relative risk for participants who underwent screening, and numbers needed to invite for screening to save one life were compared between the screening group and the control group of different starting age groups at 14-year follow-up. RESULTS: The 14-year risks of ESCC mortality were one in 55, one in 17, and one in 9 for a person screened in the starting age group of 40, 50, and 60 years old. The cumulative mortalities of ESCC in screening groups were significantly lower than control groups in starting age groups of 40 years (1.42% vs 2.38%, P = 0.033) and 50 years (4.18% vs 7.13%, P = 0.005). Relative risks for participants who underwent screening were 0.60 and 0.59 for the starting age groups of 40 and 50 years. Numbers needed to invite for screening to save one life were 104 and 34 for participants in 40 years old group and 50 years old group, respectively. CONCLUSIONS: In conclusion, people in high prevalence area of ESCC should have endoscopy screening once at their 50 years. Forty years will be preferably defined as the starting age for screening in areas with sufficient health resources.

OBJECTIVE: To explore the natural history of severe dysplasia/carcinoma in situ (SD/CIS) patients and to evaluate the efficacy of endoscopic treatment to SD/CIS patients. METHODS: Between January 2005 and December 2009, a population-based prospective screening program on esophageal squamous cell carcinoma (ESCC) was performed in Linzhou, China, with endoscopic screening plus iodine staining. All the eligible histologically confirmed SD/CIS patients were followed up through the door-to-door follow-up and local cancer registry. The endpoint was diagnosed as ESCC or the December 31st, 2016. Kaplan-Meier survival analysis and Log-rank test were used to compare the survival rates among treated and untreated patients. RESULTS: A total of 175 SD/CIS patients were enrolled and grouped by whether they received endoscopic treatment. Eleven-year cumulative incidence rates for untreated and treated SD/CIS patients were 10.7% [95% confidence interval (95% CI): 6.9-16.1] and 3.2% (95% CI: 1.4-7.0), respectively. The ESCC incidence free survival rate, and all-cause incidence and mortality free survival rates were all significantly higher in the treated patientsvs. untreated patients (P=0.043, P=0.008 and P=0.015, respectively). The ESCC mortality free survival rate showed no significant differences between the two groups (P=0.847). CONCLUSIONS: The cumulative incidence rate of SD/CIS patients to ESCC was much lower than previously reported. The Kaplan-Meier survival analysis showed that endoscopic treatment could increase the ESCC and all-cause disease-free survival rates of SD/CIS patients significantly.
ABSTRACT
OBJECTIVE: To evaluate the feasibility of DNA image cytometry (DNA-ICM) as a primary screening method for esophageal squamous cell cancer (ESCC). METHODS: A total of 5,382 local residents aged 40-69 years from three high-risk areas in China (Linzhou in Henan province, Feicheng in Shandong province and Cixian in Hebei province) from 2008 to 2011 were recruited in this population-based screening study. And 2,526 subjects declined to receive endoscopic biopsy examination with Lugol's iodine staining, while 9 and 815 subjects were excluded from liquid-based cytology and DNA-ICM test respectively due to slide quality. Finally, 2,856, 5,373 and 4,567 subjects were enrolled in the analysis for endoscopic biopsy examination, liquid-based cytology and DNA-ICM test, respectively. Sensitivity (SE), specificity (SP), negative predictive values (NPV) and positive predictive values (PPV) as well as their 95% confidence intervals (95% CI) for DNA-ICM, liquid-based cytology and the combination of the two methods were calculated. Receiver operating characteristic (ROC) curves were applied to determine the cutoff point of DNA-ICM for esophageal cancer. RESULTS: DNA-ICM results were significantly correlative with esophageal cancer and precancer lesions (χ(2)=18.016, P<0.001). The cutoff points were 5,802, 5,803 and 8,002 based on dissimilar pathological types of low grade intraepithelial neoplasia (LGIN), high grade intraepithelial neoplasia (HGIN), and ESCC, respectively, and 5,803 was chosen in this study considering the SE and SP. The SE, SP, PPV, NPV of DNA-ICM test (cutoff point 5,803) combined with liquid-based cytology [threshold atypical squamous cells of undetermined significance (ASCUS)] were separately 72.1% (95% CI: 70.3%-73.9%), 43.3% (95% CI: 41.3%-45.3%), 22.8% (95% CI: 21.1%-24.5%) and 87.0% (95% CI: 85.7%-88.3%) for LGIN, 85.7% (95% CI: 84.3%-87.1%), 41.3% (95% CI: 39.3%-43.3%), 4.6% (95% CI: 3.8%-5.4%) and 98.9% (95% CI: 98.5%-99.3%) for HGIN, and 96.0% (95% CI: 95.2%-96.8%), 40.8% (95% CI: 38.8%-42.8%), 1.7% (95% CI: 1.2%-2.2%) and 99.9% (95% CI: 99.8%-100.0%) for ESCC. CONCLUSIONS: It is possible to use DNA-ICM test as a primary screening method before endoscopic screening for esophageal cancer.
ABSTRACT
OBJECTIVE: To understand the distribution of esophageal squamous cell cancer and precursor lesions in high-risk areas of China, and to provide evidence for determining the reference ranges of detection rates in high-risk areas. METHODS: Endoscopy with Lugol's iodine staining was performed on 15 709 local residents aged 40 to 69 years old in Linzhou of Henan province and Feicheng of Shandong province from 2005-2009. 35 cases without accurate pathology diagnosis and 11 cases with vital disease before screening were excluded. 15 663 subjects were enrolled in this study. Compliance was calculated by the percentage of the people who had endoscopic screening among the target population. Chi-square test and trend chi-square test were used to compare the distribution differences in age, gender and areas of esophageal squamous cell cancer and precancer. 95% CI of the detection rates was then employed to represent the reference ranges of esophageal squamous cell cancer and precursor lesions. RESULTS: The compliance rate of screening endoscopy of this study was 49.36% (15 709/31 826) of all, and female's compliance (54.05%, 8 447/15 628) was much higher than that of male (44.83%, 7 262/16 198) (χ(2) = 88.14, P < 0.001). The detection rates of basal cell hyperplasia, low grade intraepithelial neoplasia, high grade intraepithelial neoplasia and esophageal squamous cell cancer of males were 4.17% (302/7 246), 17.22% (1 248/7 246), 1.67% (121/7 246), 0.83% (60/7 246), and were higher than that of females (3.45% (290/8 417), 14.82% (1 247/8 417), 1.41% (119/8 417), 0.48% (40/8 417), respectively). Except for high-grade intraepithelial neoplasia, the detection rates of male were higher than that of female (P values were 0.018, < 0.001, 0.960, 0.006). The detection rates of all grades of precursor lesions increased with age rising (all P values < 0.001), among which the detection rates of the mentioned four lesions for 40-44 years old were 2.69% (94/3 500), 8.11% (284/3 500), 0.40% (14/3 500), 0.14% (5/3 500), and that of 65-69 years old were 5.46% (46/843), 23.25% (196/843), 3.68% (31/843), 2.14% (18/843). The proportion of esophageal precursor lesion of Linzhou were higher than that of Feicheng observably except for esophageal squamous cell cancer (P values were < 0.001, < 0.001, < 0.001, 0.437). The detection rates of the four lesions of Linzhou and Feicheng were 4.90% (504/10 287), 17.37% (1 787/10 287), 1.79% (184/1 0287), 0.60% (62/10 287) and 1.64% (88/5 376), 13.17% (708/5 376), 1.04% (56/5 376), 0.71% (38/5 376). The 95% CI of detection rates of various lesions were, 3.78% (3.48%-4.08%) for basal cell hyperplasia, 15.93% (15.37%-16.50%) for low-grade intraepithelial neoplasia, 12.31% (11.79%-12.82%) for mild dysplasia and 3.62% (3.33%-3.91%) for moderate hyperplasia, 1.53% (1.34%-1.72%) for high-grade intraepithelial neoplasia and 0.64% (0.51%-0.76%) for esophageal squamous cell cancer, respectively. CONCLUSION: Up to 21.88% residents that were asymptomatic were suffered from esophageal squamous cancer or precursor lesions in high-risk areas in China. The distribution of esophageal squamous cell cancer and precursor lesions was closely related to the gender and the age, which suggested that males were supposed to be paid more attention to.

A novel position-sensitive linear winding silicon drift detector (LWSDD) was designed and simulated. On the frontside (anode side), the collecting anodes were set on both sides of the detector, and an S-shaped linear winding cathode strip was arranged in the middle, which can realize independent voltage division and reduce the complexity of external bias resistor chain compared with the traditional linear silicon drift detector. The detectors were arranged in a butterfly shape, which increased the effective area of the detectors and improved the collection efficiency. The linear winding silicon drift detector can obtain one-dimensional position information by measuring the drift time of electrons. The 2D position information of the incident particle is obtained from the anodes coordinates of the readout signal. One-dimensional analytically exact solutions of electric potential and field were obtained for the first time for the linear winding silicon drift detector. The simulation results show that the electric potential distribution inside the detector is uniform, and the "drift channel" inside the detector points to the collecting anodes on both sides, which proves the reasonable and feasible design of the linear winding silicon drift detector.
ABSTRACT
INTRODUCTION: Obesity has previously been correlated with an elevated risk of reproductive system diseases in women. The waist-hip ratio (WHR) has been shown to be correlated with visceral fat, making it one of the most commonly used indicators of abdominal obesity. However, little is known about the relationship between WHR and infertility. Therefore, the aim of this study was to evaluate the effect of the WHR on infertility in women of childbearing age. METHODS: The study used cross-sectional data from women aged 20-45 who participated in the National Health and Nutrition Examination Survey (NHANES), which was conducted between 2017 and 2020. We collected details of their waist circumference, hip circumference, fertility status, and several other essential variables. We used multivariate logistic regression analysis and subgroup analyses to assess the association between WHR and infertility. RESULTS: There were 976 participants, with 12.0% (117/976) who experienced infertility. After adjusting for potential confounding factors, our multivariate logistic regression analysis revealed that every 0.1 unit increase in WHR resulted in a more than 35% higher risk of infertility (odds ratio [OR; 95% confidence interval [CI]: 1.35 [1.01â¼1.81], p = 0.043). Compared to the group with WHR <0.85, the risk of infertility increased in the group with WHR ≥0.85, with an adjusted OR of 1.74 (95% CI: 1.06â¼2.85). When WHR was treated as a continuous variable, it was observed that each 0.1 unit increase in WHR was associated with a relatively high risk in the secondary infertility population after adjusting all covariates, with an OR of 1.66 (95% CI: 1.14â¼2.40, p = 0.01). When WHR was analyzed as a categorical variable, the group with WHR ≥0.85 exhibited a significantly higher risk of secondary infertility than the group with WHR <0.85, with the OR of 2.75 (95% CI: 1.35-5.59, p = 0.01) after adjusting for all covariates. Furthermore, the interaction analysis indicated that there was a significant interaction between age status on WHR and the risk of infertility. CONCLUSION: WHR showed a positive correlation with the risk of infertility. This study highlights the importance of effectively managing abdominal fat and promoting the maintenance of optimal WHR levels to mitigate the progression of infertility, particularly for younger women.
ABSTRACT
BACKGROUND: The diabetic foot is a common cause of disability and death, and comorbid foot infections usually lead to prolonged hospitalization, high healthcare costs, and a significant increase in amputation rates. And most diabetic foot trauma is complicated by lower extremity arteriopathy, which becomes an independent risk factor for major amputation in diabetic foot patients. AIM: To establish the efficacy and safety of endovascular revascularization (ER) combined with vacuum-assisted closure (VAC) for the treatment of diabetic foot. METHODS: Clinical data were collected from 40 patients with diabetic foot admitted to the Second Affiliated Hospital of Soochow University from April 2018 to April 2022. Diabetic foot lesions were graded according to Wagner's classification, and blood flow to the lower extremity was evaluated using the ankle-brachial index test and computerized tomography angiography of the lower extremity arteries. Continuous subcutaneous insulin infusion pumps were used to achieve glycemic control. Lower limb revascularization was facilitated by percutaneous tran-sluminal balloon angioplasty (BA) or stenting. Wounds were cleaned by nibbling debridement. Wound granulation tissue growth was induced by VAC, and wound repair was performed by skin grafting or skin flap transplantation. RESULTS: Of the 35 cases treated with lower limb revascularization, 34 were successful with a revascularization success rate of 97%. Of these, 6 cases underwent stenting after BA of the superficial femoral artery, and 1 received popliteal artery stent implantation. In the 25 cases treated with infrapopliteal artery revascularization, 39 arteries were reconstructed, 7 of which were treated by drug-coated BA and the remaining 32 with plain old BA. VAC was performed in 32 wounds. Twenty-four cases of skin grafting and 2 cases of skin flap transplantation were performed. Two patients underwent major amputations, whereas 17 had minor amputations, accounting for a success limb salvage rate of 95%. CONCLUSION: ER in combination with VAC is a safe and effective treatment for diabetic foot that can significantly improve limb salvage rates. The use of VAC after ER simplifies and facilitates wound repair.
ABSTRACT
BACKGROUND: Although significant advances have been made in the treatment of multiple myeloma (MM), leading to unprecedented response and survival rates among patients, the majority eventually relapse, and a cure remains elusive. This situation is closely related to an incomplete understanding of the immune microenvironment, especially monocytes/macrophages in patients with treatment-naïve MM. The aim of this study was to provide insight into the immune microenvironment, especially monocytes/macrophages, in patients with treatment-naïve MM. METHODS: This study used the single-cell RNA sequencing (scRNA-seq) data of both patients with MM and heathy donors to identify immune cells, including natural killer (NK) cells, T cells, dendritic cells (DCs), and monocytes/macrophages. Transcriptomic data and flow cytometry analysis of monocytes/macrophages were used to further examine the effect of monocytes/macrophages in treatment-naïve MM patients. RESULTS: A significant difference was observed between the bone marrow (BM) immune cells of the healthy controls and treatment-naïve MM patients through scRNA-seq. It is noteworthy that, through an scRNA-seq data analysis, this study found that interferon (IFN)-induced NK/T cells, terminally differentiated effector memory (TEMRA) cells, T-helper cells characterized by expression of IFN-stimulated genes (ISG + Th cells), IFN-responding exhausted T cells, mannose receptor C-type 1 (MRC1) + DCs, IFN-responding DCs, MHCII + DCs, and immunosuppressive monocytes/macrophages were enriched in patients with treatment-naïve MM. Significantly, transcriptomic data of monocytes/macrophages demonstrated that "don't eat me"-related genes and IFN-induced genes increase in treatment-naïve MM patients. Furthermore, scRNA-seq, transcriptomic data, and flow cytometry also showed an increased proportion of CD16 + monocytes/macrophages and expression level of CD16. Cell-cell communication analysis indicated that monocytes/macrophages, whose related important signaling pathways include migration inhibitory factor (MIF) and interleukin 16 (IL-16) signaling pathway, are key players in treatment-naïve MM patients. CONCLUSIONS: Our findings provide a comprehensive and in-depth molecular characterization of BM immune cell census in MM patients, especially for monocytes/macrophages. Targeting macrophages may be a novel treatment strategy for patients with MM.

BACKGROUND: Microbiota may be associated with esophageal squamous cell carcinoma (ESCC) development. However, it is not known the predictive value of microbial biomarkers combining epidemiological factors for the early detection of ESCC and precancerous lesions. METHODS: A total of 449 specimens (esophageal swabs and saliva) were collected from 349 participants with different esophageal statuses in China to explore and validate ESCC-associated microbial biomarkers from genes level to species level by 16S rRNA sequencing, metagenomic sequencing and real-time quantitative polymerase chain reaction. RESULTS: A bacterial biomarker panel including Actinomyces graevenitzii (A.g_1, A.g_2, A.g_3, A.g_4), Fusobacteria nucleatum (F.n_1, F.n_2, F.n_3), Haemophilus haemolyticus (H.h_1), Porphyromonas gingivalis (P.g_1, P.g_2, P.g_3) and Streptococcus australis (S.a_1) was explored by metagenomic sequencing to early detect the participants in Need group (low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia and ESCC) vs participants without these lesions as the Noneed group. Significant quantitative differences existed for each microbial target in which the detection efficiency rate was higher in saliva than esophageal swab. In saliva, the area under the curve (AUC) based on the microbial biomarkers (A.g_4 â© P.g_3 â© H.h_1 â© S.a_1 â© F.n_2) was 0.722 (95% CI 0.621-0.823) in the exploration cohort. Combining epidemiological factors (age, smoking, drinking, intake of high-temperature food and toothache), the AUC improved to 0.869 (95% CI 0.802-0.937) in the exploration cohort, which was validated with AUC of 0.757 (95% CI 0.663-0.852) in the validation cohort. CONCLUSIONS: It is feasible to combine microbial biomarkers in saliva and epidemiological factors to early detect ESCC and precancerous lesions in China.

AIMS: This study aimed to investigate the association of soluble suppression of tumorigenicity-2 (sST2) measured by point-of-care testing assay with clinical outcomes in patients hospitalized with heart failure after adjusting for other predictors including N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT). METHODS: A total of 1726 consecutive patients hospitalized with heart failure from July 2015 to December 2021 were enrolled. Baseline serum sST2 concentrations were measured by immunofluorescence assay. Primary endpoint event was the composite of all-cause death, heart transplantation, or left ventricular assist device. RESULTS: During the median follow-up duration of 682 days, 434 patients (25.1%) suffered from primary endpoint events. Baseline sST2 remained an independent predictor of the primary endpoint event in patients hospitalized with heart failure after adjusting for other predictors including NT-proBNP and hs-cTnT [per log (unit) increase, adjusted hazard ratio (HR) (95% confidence interval) (CI): 1.20 (1.09, 1.32), P < 0.001]. And baseline sST2 had a better prognostic value for patients with chronic decompensated heart failure [per log (unit) increase, adjusted HR (95% CI): 1.19 (1.07, 1.31)] than for those with acute new onset heart failure [per log (unit) increase, adjusted HR (95% CI): 1.28 (0.94, 1.75), P value for interaction <0.001], as well as a better prognostic value for patients with New York Heart Association (NYHA) functional class I-II [per log (unit) increase, adjusted HR (95% CI): 1.67 (1.11, 2.52)] than for those with NYHA functional class III-IV [per log (unit) increase, adjusted HR (95% CI): 1.18 (1.07, 1.31), P value for interaction <0.001]. Baseline sST2 was also a good predictor of the primary endpoint event in patients hospitalized with heart failure at 1 month, 3 months, 1 year and 2 years (area under the curve: 0.789, 0.775, 0.736 and 0.733, respectively), and the best cut-off values were 27.2 ng/ml, 27.1 ng/ml, 27.1 ng/ml and 25.1 ng/ml, respectively. Furthermore, baseline sST2 could provide additional prognostic value when added to baseline NT-proBNP and hs-cTnT (all P values <0.05). According to the category of elevated biomarkers (including NT-proBNP, hs-cTnT, and sST2), patients with three elevated biomarkers had a higher risk of the primary endpoint event compared with those with one or two elevated biomarkers (all P values <0.05). CONCLUSIONS: Baseline sST2 remained an independent predictor of adverse events after adjusting for other predictors including NT-proBNP and hs-cTnT, particularly in patients with chronic decompensated heart failure and NYHA functional class I-II. And in the basis of baseline NT-proBNP and hs-cTnT, adding baseline sST2 could provide additional prognostic value for patients hospitalized with heart failure.
