The prevalence of monotherapy and combination therapy in hypertension in China from 2019 to 2021: A nationwide population-based cross-sectional study.

There are no nationwide surveys on antihypertensive drugs in China. In order to assess the current status of antihypertensive drug therapy in patients with hypertension and analyzed factors that may affect combination therapy, using convenience sampling, we recruited 305,624 patients with hypertension from the Chinese Cardiovascular Association Database-Hypertension Center between January 2019 and December 2021. Chi-squared test was performed to analyze the administered antihypertensive drug types and their combinations in different hospital settings. Logistic regression was used to assess the factors influencing combination therapy. We found around 33.1% of the participants had stage 2 and above hypertension, of which 67.9% were treated with combination therapy. In community or general hospitals, the most common monotherapy was calcium channel blockers (CCB), angiotensin-converting enzyme inhibitor/angiotensin II receptor inhibitor (ACEI/ARB) and diuretic were the main single-pill combinations (SPCs), and ACEI/ARB and CCB were the main free combination. From 2019 to 2021, the rates of combination therapy increased (58.8%-64.1%) with SPCs from 25.9% to 31.0% and free combination from 31.9% to 32.6%. Patients aged < 60 years, with stage 2 and above hypertension, with an education level of high school and above, visiting general hospitals, living in the eastern region of China, with hypertension risk factors and comorbidities, and without anxiety or depression were more likely to receive combination therapy (all P < .05). The combination therapy use rate increased yearly and the rate of SPCs rose obviously. Individual, hospital, and regional differences in patients with hypertension influenced combination therapy.

Identification of diabetic retinopathy classification using machine learning algorithms on clinical data and optical coherence tomography angiography.

BACKGROUND: To apply machine learning (ML) algorithms to perform multiclass diabetic retinopathy (DR) classification using both clinical data and optical coherence tomography angiography (OCTA). METHODS: In this cross-sectional observational study, clinical data and OCTA parameters from 203 diabetic patients (203 eye) were used to establish the ML models, and those from 169 diabetic patients (169 eye) were used for independent external validation. The random forest, gradient boosting machine (GBM), deep learning and logistic regression algorithms were used to identify the presence of DR, referable DR (RDR) and vision-threatening DR (VTDR). Four different variable patterns based on clinical data and OCTA variables were examined. The algorithms' performance were evaluated using receiver operating characteristic curves and the area under the curve (AUC) was used to assess predictive accuracy. RESULTS: The random forest algorithm on OCTA+clinical data-based variables and OCTA+non-laboratory factor-based variables provided the higher AUC values for DR, RDR and VTDR. The GBM algorithm produced similar results, albeit with slightly lower AUC values. Leading predictors of DR status included vessel density, retinal thickness and GCC thickness, as well as the body mass index, waist-to-hip ratio and glucose-lowering treatment. CONCLUSIONS: ML-based multiclass DR classification using OCTA and clinical data can provide reliable assistance for screening, referral, and management DR populations.

A mapping-knowledge-domain analysis of ERP research on language processing.

The event-related potentials (ERPs) technique represents a newly developed methodology in cognitive neuroscience and has significantly extended the scope of linguistic studies, offering valuable insights into cognitive processes related to language. While extant literature reviews have addressed specific facets of ERP research on language processing, a comprehensive overview of this domain remains notably absent. This study aims to fill this gap by pioneering a mapping-knowledge-domain analysis of ERP research on language processing using Citespace, a visualized bibliometric software. The current study conducted a meticulous survey and evaluation of relevant literature extracted from the Web of Science core collection. Initially, this study outlines the spatial-temporal distribution within this domain. Subsequently, employing document co-citation analysis, keyword co-occurrence analysis, cluster analysis, and burst detection analysis, this study delved deeper into the research landscape. Findings reveal that key areas in ERP research on language processing predominantly focus on sentence comprehension, reading comprehension, and mismatch negativity, with notable emphasis on topics such as speech perception, temporal dynamics, and working memory. The current study advocates for future investigations to concentrate on larger linguistic units, explore the integration of ERP components and their functional significance, and scrutinize individual differences among participants. These directions are imperative for advancing the understanding of language processing mechanisms.

Comparison of bleb morphologies between phacoemulsification combined with Ex-PRESS mini shunt implantation, phacotrabeculectomy and trabeculectomy alone: a two-year retrospective in vivo confocal microscopy study.

BACKGROUND: To compare the bleb morphologies of phacoemulsification combined with Ex-PRESS implantation (Phaco-ExPRESS), phaco trabeculectomy (Phaco-Trab), and trabeculectomy (Trab) in postoperative two years. METHODS: Patients with primary open-angle glaucoma (POAG) with or without cataracts were included in this study. All patients underwent surgeries of either Phaco-ExPRESS, Phaco-Trab, or Trab. The morphologic structures of the filtering bleb, including microcysts area, hyperreflective dot density, and stromal connective tissue under in vivo confocal microscope (IVCM), were compared between the three groups. The data were collected preoperatively and postoperatively at 2 weeks, 1 month, 3 months, 6 months, 12 months, 18 months, and 24 months. RESULTS: Eighty-nine eyes from 89 patients were enrolled, including 32 in the Phaco-ExPRESS group, 25 in the Phaco-Trab group, and 32 in the Trab group. In a 24-month follow-up, bleb morphologies in Phaco-ExPRESS were similar to the Trab group. The area of epithelial microcysts was significantly increased in Phaco-ExPRESS and Trab groups while significantly decreased in Phaco-Trab. At postoperative 24 months, the complete success rate was 65.1% in Phaco-ExPRESS, 32.0% in Phaco-Trab, and 59.4% in the Trab group (P = 0.03). The phaco-Trab group had more postoperative anti-glaucoma medications than the other two groups (P < 0.05). CONCLUSIONS: Phaco-ExPRESS group and Trab group had similar blebs morphologies in IVCM, with larger microcyst area, looser connective tissue, and less inflammation than Phaco-Trab, indicating that the function of blebs in the Phaco-ExPRESS and Trab group, was more potent than that of Phaco-Trab. All these surgical methods provided adequate IOP control, but Phaco-Trab required more anti-glaucoma medications.

Global, regional and national burden of retinopathy of prematurity among childhood and adolescent: a spatiotemporal analysis based on the Global Burden of Disease Study 2019.

BACKGROUND: This study aimed to provide a comprehensive assessment of burden estimates and the secular trend of vision loss due to retinopathy of prematurity (ROP) among people younger than 20 years, at the global, regional and national levels. METHODS: Data were obtained from the Global Burden of Disease Study 2019 database. The average annual percentage change (AAPC) was calculated to quantify the temporal trends in the measures of vision loss. RESULTS: In 2019, the global age-standardised rates (ASRs) of prevalence per 100 000 population was 86.4 for vision loss, specifically, 35 for moderate vision loss, 19.9 for severe vision loss, 31.6 for blindness due to ROP among people younger than 20 years. Moreover, the ASR of years lived with disability per 100 000 was 10.6 for vision loss, specifically, 1.1 for moderate vision loss, 3.6 for severe vision loss, 5.9 for blindness, respectively. From 1990 to 2019, the ASR of prevalence of blindness and vision loss due to ROP significantly increased, while its burden slightly decreased. Males showed higher ASR of prevalence than females in 2019, whereas females have larger increasing trend than males from 1990 to 2019. The global highest ASR of disease burden was observed in South Asia and Southern sub-Saharan Africa, as well as low sociodemographic index (SDI) regions in 2019. CONCLUSIONS: Globally, although the burden decreased, the prevalence of childhood and adulthood vision loss due to ROP continues to increase. Reasonable resource allocation and advanced intervention are recommended to prevent and control the vision loss due to ROP.

Extent of surgical resection for radiologically subsolid T1N0 invasive lung adenocarcinoma: When is a wedge resection acceptable?

OBJECTIVE: To evaluate whether wedge resection (WR) was appropriate for the patients with peripheral T1 N0 solitary subsolid invasive lung adenocarcinoma. METHODS: Patients with peripheral T1N0 solitary subsolid invasive lung adenocarcinoma who received sublobar resection were retrospectively reviewed. Clinicopathologic characteristics, 5-year recurrence-free survival, and 5-year lung cancer-specific overall survival were analyzed. Cox regression model was used to elucidate risk factors for recurrence. RESULTS: Two hundred fifty-eight patients receiving WR and 1245 patients receiving segmentectomy were included. The mean follow-up time was 36.87 ± 16.21 months. Five-year recurrence-free survival following WR was 96.89% for patients with ground-glass nodule (GGN) ≤2 cm and 0.25< consolidation-to-tumor ratio (CTR) ≤0.5, not statistically different from 100% for those with GGN≤2 cm and CTR ≤0.25 (P = .231). The 5-year recurrence-free survival was 90.12% for patients with GGN between 2 and 3 cm and CTR ≤0.5, significantly lower than that of patients with GGN ≤2 cm and CTR ≤0.25 (P = .046). For patients with GGN≤2 cm and 0.25

Recycling Waste Glyceroborate to Aqueous Lubricant for Tribological Applications.

The present study attempts to explore the direct recyclability of glyceroborate from medicine pharmaceutical production wastewater into an aqueous lubricant instead of conventional waste processing methods from the tribological view. In order to determine the tribological feasibility, the physicochemical properties of crude pharmaceutical wastewater are investigated and compared with those of pure glycerol to access their potential lubrication properties. The results demonstrated that the crude pharmaceutical wastewater has better friction-reducing and antiwear properties under the same working conditions. Besides outstanding lubricating properties, the friction-induced formation of borate tribo-film and intermediate FeOOH compound favors lowering of the shear stress between the rubbing surfaces. This finding better provides an alternative to transform glyceroborate from medicine pharmaceutical production wastewater after simple distillation processing to a potential aqueous lubricant.

Associations of concomitant retinopathy and depression with mortality in a nationally representative population.

OBJECTIVE: To evaluate the interaction effects between retinopathy and depression on mortality risks in genral population and subpopulation with diabetes. METHODS: Prospective analyses were conducted on data from the National Health and Nutrition Examination Surveys study. Associations of retinopathy, depression and their interaction with all-cause, cardiovascular disease (CVD)-specific, cancer-specific and other-specific mortality risk were estimated using Kaplan-Meier curves and multivariate Cox proportional hazards models. RESULTS: Among 5367 participants, the weighted prevalence of retinopathy and depression was 9.6 % and 7.1 %, respectively. After a follow-up period of 12.1 years, 1295 deaths (17.3 %) occurred. Retinopathy was associated with an increased risk of all-cause (hazard ratio [HR]; 95 % confidence interval [CI]) (1.47; 1.27-1.71), CVD-specific (1.87; 1.45-2.41), and other-specific (1.43; 1.14-1.79) mortality. Similar relationship was observed between depression and all-cause mortality (1.24; 1.02-1.52). Retinopathy and depression had a positive multiplicative and additive interaction effect on all-cause (Pinteraction = 0.015; relative excess risk of interaction [RERI] 1.30; 95 % CI 0.15-2.45) and CVD-specific mortality (Pinteraction = 0.042; RERI 2.65; 95 % CI -0.12-5.42). Concomitant retinopathy and depression was more markedly associated with all-cause (2.86; 1.91-4.28), CVD-specific (4.70; 2.57-8.62), and other-specific mortality risks (2.18; 1.14-4.15) compared to those without retinopathy and depression. These associations were more pronounced in the diabetic participants. CONCLUSIONS: The co-occurrence of retinopathy and depression increases the risk of all-cause and CVD-specific mortality among middle-aged and older adults in the United States, especially in population with diabetes. Focus on diabetic patients and active evaluation and intervention of retinopathy with depression may improve their quality of life and mortality outcomes.

Bleeding-related re-exploration following pulmonary resection: a report of a single-center experience.

PURPOSE: Postoperative bleeding is a potentially fatal complication after lung surgery and usually requires re-operation. The aim of this study was to analyze the characteristics of bleeding-related re-exploration following pulmonary resection and reduce the incidence of this complication. METHODS: From January 2016 to December 2020, 14,104 patients underwent pulmonary resection for lung cancer or pulmonary nodule at Fudan University Shanghai Cancer Center, China. We evaluated cases with bleeding-related re-exploration, and analyzed the relationship between postoperative bleeding and clinical characteristics. We further developed a protocol to reduce the proportion of bleeding-related re-exploration in our center. RESULTS: Bleeding-related re-exploration occurred in 85 (0.60%) out of 14,104 patients. The sources of postoperative bleeding included surgical incision (20, 23.53%), parietal pleura (20, 23.53%), bronchial artery (14, 16.47%), lung parenchyma (13, 15.29%), pulmonary vessel (5, 5.88%) and rare source of bleeding. There were various patterns of postoperative bleeding. Open thoracotomy had a significantly higher bleeding rate than video-assisted thoracoscopic surgery (VATS) (1.27% vs 0.34%, p < 0.0001). The bleeding rate of pneumonectomy, lobectomy, segmentectomy and wedge resection was significantly different (1.78%, 0.88%, 0.46% vs 0.28%, p < 0.0001). All patients were discharged successfully except for one patient died of respiratory failure. A protocol based on these findings was developed to reduce the proportion of bleeding-related re-exploration in our center. CONCLUSION: Our findings revealed that the source of bleeding, surgical approach and procedure affected the pattern of postoperative bleeding. Postoperative bleeding could be managed properly on the timely decision of re-exploration considering its origin, severity, onset and risk factors.

Associations of COVID-19 lockdown with gestational length and preterm birth in China.

BACKGROUND: The effects of COVID-19 lockdown measures on maternal and fetal health remain unclear. We examined the associations of COVID-19 lockdown with gestational length and preterm birth (PTB) in a Chinese population. METHODS: We obtained medical records of 595,396 singleton live infants born between 2015 and 2020 in 5 cities in Guangdong Province, South China. The exposed group (N = 101,900) included women who experienced the COVID-19 Level I lockdown (1/23-2/24/2020) during pregnancy, while the unexposed group (N = 493,496) included women who were pregnant during the same calendar months in 2015-2019. Cumulative exposure was calculated based on days exposed to different levels of emergency responses with different weighting. Generalized linear regression models were applied to estimate the associations of lockdown exposure with gestational length and risk of PTB (< 37 weeks). RESULTS: The exposed group had a shorter mean gestational length than the unexposed group (38.66 vs 38.74 weeks: adjusted ß = - 0.06 week [95%CI, - 0.07, - 0.05 week]). The exposed group also had a higher risk of PTB (5.7% vs 5.3%; adjusted OR = 1.08 [95%CI, 1.05, 1.11]). These associations seemed to be stronger when exposure occurred before or during the 23rd gestational week (GW) than during or after the 24th GW. Similarly, higher cumulative lockdown exposure was associated with a shorter gestational length and a higher risk of PTB. CONCLUSIONS: The COVID-19 lockdown measures were associated with a slightly shorter gestational length and a moderately higher risk of PTB. Early and middle pregnancy periods may be a more susceptible exposure window.

DDX56 modulates post-transcriptional Wnt signaling through miRNAs and is associated with early recurrence in squamous cell lung carcinoma.

BACKGROUND: Early recurrence is a major obstacle to prolonged postoperative survival in squamous cell lung carcinoma (SqCLC). The molecular mechanisms underlying early SqCLC recurrence remain unclear, and effective prognostic biomarkers for predicting early recurrence are needed. METHODS: We analyzed primary tumor samples of 20 SqCLC patients using quantitative proteomics to identify differentially-expressed proteins in patients who experienced early versus late disease recurrence. The expression and prognostic significance of DDX56 was evaluated using a SqCLC tumor tissue microarray and further verified using different online databases. We performed in vitro and in vivo experiments to obtain detailed molecular insight into the functional role of DDX56 in SqCLC. RESULTS: We found that DDX56 exhibited increased expression in tumors of patients who experienced early versus late disease recurrence. Increased DDX56 expression in SqCLC tumors was subsequently confirmed as an independent prognostic factor of poor recurrence-free survival in independent SqCLC cohorts. Functionally, DDX56 promotes SqCLC cell growth and migration in vitro, and xenograft tumor progression in vivo. Mechanistically, DDX56 post-transcriptionally promotes expression of multiple Wnt signaling pathway-related genes, including CTNNB1, WNT2B, and represses a subset of miRNAs, including miR-378a-3p, a known suppressor of Wnt signaling. Detailed analysis revealed that DDX56 facilitated degradation of primary miR-378a, leading to down-regulation of mature miR-378a-3p and thus derepression of the target gene WNT2B. CONCLUSION: We identified DDX56 as a novel independent prognostic biomarker that exerts its oncogenic effects through miRNA-mediated post-transcriptional regulation of Wnt signaling genes to promote early SqCLC recurrence. DDX56 may assist in identifying SqCLC patients at increased risk of early recurrence and who could benefit from Wnt signaling-targeted therapies.

Is flexible bronchoscopy necessary in the preoperative workup of patients with peripheral cT1N0 subsolid lung cancer? -a prospective multi-center cohort study.

BACKGROUND: Necessity of flexible bronchoscopy (FB) examination as a routine preoperative work-up for peripheral clinical T1N0 subsolid lung cancer was unknown. METHODS: This was a prospective, multi-center clinical trial (NCT03591445). Patients with peripheral GGO nodules (GGNs) who were candidates for surgical resection were enrolled. FB examination was performed preoperatively. Surgical plan could be changed if any aberrant histologic and anatomic findings were detected by FB examination. Primary endpoint was the rate that surgical plan was changed by positive FB findings. Secondary endpoints were rate of positive FB findings and rate of procedural complications. RESULTS: Six hundred and fifteen patients with peripheral subsolid nodules detected by thoracic CT were enrolled. There were 187 (30.4%) male and 428 (69.6%) female patients, mean age was 54.85±10.41 y (range, 26-78). 262 (42.6%) patients had pure GGNs and 353 (57.4%) patients had part-solid nodules. Mean size of nodules was 13.87±6.37 mm (range, 5-30). FB examinations confirmed one (0.16%) adenocarcinoma, seven (1.14%) bronchial variations, one (0.16%) segmental bronchostenosis, one (0.16%) segmental bronchial occlusion and one (0.16%) bronchial inflammation. No complications of FB examinations occurred. 568 (92.35%) thoracoscopic and 47 (7.65%) open surgeries were performed. No established surgical plan was changed by positive FB findings. Final pathologies revealed 26 (4.2%) adenocarcinoma in situ (AIS), 240 (39%) minimal invasive adenocarcinomas (MIAs), 343 (55.8%) invasive adenocarcinomas (IADs), one (0.2%) adenosquamous cell carcinoma, one (0.2%) squamous cell carcinoma, two (0.3%) atypical adenoid hyperplasia and two (0.3%) inflammations. CONCLUSIONS: FB examination was unnecessary in the preoperative assessment of peripheral clinical T1N0 subsolid lung cancer.

Esophagectomy With Three-Field Versus Two-Field Lymphadenectomy for Middle and Lower Thoracic Esophageal Cancer: Long-Term Outcomes of a Randomized Clinical Trial.

INTRODUCTION: The optimal extent of lymphadenectomy during esophagectomy remains unclear. In this trial, we aim to clarify whether three-field (cervical-thoracic-abdominal) lymphadenectomy improved patient survival over two-field (thoracic-abdominal) lymphadenectomy for esophageal cancer. METHODS: Between March 2013 and November 2016, a total of 400 patients with middle and lower thoracic esophageal cancer were included and randomly assigned to undergo esophagectomy with either three- or two-field lymphadenectomy at a 1:1 ratio. Analyses were done according to the intention-to-treat principle. The primary end point was overall survival (OS), calculated from the date of randomization to the date of death from any cause. RESULTS: Demographic characteristics were similar in the two arms. The median follow-up time was 55 months (95% confidence interval [CI]: 52-58). OS (hazard ratio [HR] = 1.019, 95% CI: 0.727-1.428, p = 0.912) and the disease-free survival (DFS) (HR = 0.868, 95% CI: 0.636-1.184, p = 0.371) were comparable between the two arms. The cumulative 5-year OS was 63% in the three-field arm, as compared with 63% in the two-field arm; 5-year DFS was 59% and 53%, respectively. On the basis of whether the patients had mediastinal or abdominal lymph node metastasis or not, OS was also comparable between the two arms. In this cohort, only advanced tumor stage (pathologic TNM stages III-IV) was identified as the risk factor associated with reduced OS (HR = 3.330, 95% CI: 2.140-5.183, p < 0.001). CONCLUSIONS: For patients with middle and lower thoracic esophageal cancer, there was no improvement in OS or DFS after esophagectomy with three-field lymphadenectomy over two-field lymphadenectomy.

Mental Health Literacy of Non-mental Health Nurses: A Mental Health Survey in Four General Hospitals in Hunan Province, China.

Background: The high numbers of patients with mental illness, especially those who are misdiagnosed or delayed in treatment in China, have imposed a huge burden on the country and the society. This study was designed to investigate the mental health literacy (MHL) of non-mental health nurses. Method: A cross-sectional survey was designed, and a convenient cluster sampling method was applied. We presented evidence on 601 nurses from the non-mental health department in four hospitals in Hengyang city, China. One-third of the vignettes were diagnosed with schizophrenia, depression, or generalized anxiety disorder (GAD). Result: The correct identification rates for schizophrenia, depression, and GAD vignettes reached 38.9, 56.2, and 17.5%, respectively. The majority of the participants deemed that the person in each vignette needed professional help, and most of them preferred professional medical help and lifestyle interventions. As for the likely outcome for the persons described in each vignette, more than half of the participants thought that with professional help, the patients would make a full recovery, but problems would probably recur. Conclusion: The MHL of non-mental health nurses is insufficient in China. This condition is particularly applicable in the case of GAD. Thus, the country must implement more mental health education programs to improve the MHL of non-mental health nurses.

Activated CX3CL1/Smad2 Signals Prevent Neuronal Loss and Alzheimer's Tau Pathology-Mediated Cognitive Dysfunction.

Neurofibrillary tangles likely cause neurodegeneration in Alzheimer's disease (AD). We demonstrate that the CX3CL1 C-terminal domain can upregulate neurogenesis, which may ameliorate neurodegeneration. Here we generated transgenic (Tg-CX3CL1) mice by overexpressing CX3CL1 in neurons. Tg-CX3CL1 mice exhibit enhanced neurogenesis in both subgranular and subventricular zones. This enhanced neurogenesis correlates well with elevated expression of TGF-ß2 and TGF-ß3, and activation of their downstream signaling molecule Smad2. Intriguingly, the enhanced adult neurogenesis was mitigated when Smad2 expression was deleted in neurons, supporting a role for the CX3CL1-TGF-ß2/3-Smad2 pathway in the control of adult neurogenesis. When Tg-CX3CL1 mice were crossed with Alzheimer's PS19 mice, which overexpress a tau P301S mutation and exhibit age-dependent neurofibrillary tangles and neurodegeneration, overexpressed CX3CL1 in both male and female mice was sufficient to rescue the neurodegeneration, increase survival time, and improve cognitive function. Hence, we provide in vivo evidence that CX3CL1 is a strong activator of adult neurogenesis, and that it reduces neuronal loss and improves cognitive function in AD.SIGNIFICANCE STATEMENT This study will be the first to demonstrate that enhanced neurogenesis by overexpressed CX3CL1 is mitigated by disruption of Smad2 signaling and is independent of its interaction with CX3CR1. Overexpression of CX3CL1 lengthens the life span of PS19 tau mice by enhancing adult neurogenesis while having minimal effect on tau pathology. Enhancing neuronal CX3CL1, mainly the C-terminal fragment, is a therapeutic strategy for blocking or reversing neuronal loss in Alzheimer's disease or related neurodegenerative disease patients.

Association of Diabetes With Central Corneal Thickness Among a Multiethnic Asian Population.

Importance: Thicker or thinner central corneas may lead to either overestimation or underestimation of intraocular pressure, which is the most important causal and treatable risk factor for glaucoma. However, the findings on the associations between diabetes, random glucose, and glycated hemoglobin A1c (HbA1c) with central corneal thickness (CCT) are conflicting. Objective: To evaluate the associations between diabetes, random glucose, and HbA1c with CCT in a multiethnic Asian population. Design, Setting, and Participants: Cross-sectional analysis of the Singapore Epidemiology of Eye Diseases (SEED) Study conducted from 2004 to 2011. A total of 10 033 Chinese, Malay, and Indian individuals 40 years or older residing in Singapore were recruited. Participants with incomplete information on diabetes status (448 participants), prior refractive or cataract surgery (1940 eyes), and corneal edema or dystrophy (29 eyes) were excluded. A meta-analysis was conducted to estimate the overall association of diabetes with CCT. Exposures: Standardized clinical examinations and interviewer-administered questionnaire to collect information about demographic, systemic, and ocular factors. Main Outcomes and Measures: Measurement of CCT using ultrasound pachymetry. Results: A total of 8846 adults (mean [SD] age, 57.9 [9.9] years; 4447 women [50.3%]) (17 201 eyes) were included in the final analyses. The CCT profile was similar among participants with and without diabetes (mean [SD] CCT, 545.3 [33.7] µm vs 544.8 [33.9] µm; P = .39). Following adjustments of age, sex, ethnicity, corneal curvature, axial length, and body mass index, CCT was a mean (SD) of 4.9 (0.8) µm (95% CI, 3.3-6.5 µm) thicker in patients with diabetes than those without diabetes. Multivariable analyses also showed that thicker CCT was associated with higher random glucose (per 10 mg/dL [to convert to mmol/L, multiply by 0.0555], ß = 0.3; 95% CI, 0.2-0.4) and higher HbA1c (per percentage, ß = 1.5; 95% CI, 1.0-2.1) (all P < .001). These associations were significant in the subgroup with diabetes but not in the subgroup without diabetes. A meta-analysis including 12 previous population- and clinical-based studies showed that CCT was 12.8 µm (95% CI, 8.2-17.5 µm) thicker in eyes of patients with diabetes. Conclusions and Relevance: These findings suggest that diabetes and hyperglycemia were associated with thicker CCT. This study provides useful information on the interpretation of intraocular pressure in patients with diabetes.

Stigmatizing Attitudes Towards Mental Disorders Among Non-Mental Health Professionals in Six General Hospitals in Hunan Province.

Background: There have been few studies on the stigma associated with mental disorders among non-mental health professionals in general hospitals in China. This study seeks to explore mental health-related stigma and the desire for social distance among non-mental health professionals in general hospitals in Hunan Province in China. Methods: The study was carried out with 1123 non-mental health professionals in six general hospitals in Hunan Province by using a questionnaire with a case vignette describing either schizophrenia, depression, or generalized anxiety disorder (GAD). Questions were asked about the attitudes of participants and other people towards individuals with mental disorders and the willingness to come into contact with them. Results: The people described in the vignette were considered dangerous by 84.4% of participants for schizophrenia, 72.0% of participants for depression, and 63.1% of participants for GAD. Besides being dangerous, people with schizophrenia were perceived as unpredictable and as the least suitable for voting for as a politician or employing. Around 50% of participants believed the problems described in the vignette were due to personal weakness. Over 70% of the non-mental health professionals were not willing to have the people described in the vignette marry into their family. The participants had gained their mental health-related knowledge mainly through the media, mostly from newspapers. Conclusions: The current study found a significant stigma towards individuals with mental disorders and a desire for social distance from such people among non-mental health professionals in general hospitals in Hunan Province. Anti-stigma interventions should focus on addressing non-mental health professionals' beliefs on dangerousness and unpredictability.

A B7-CD28 family based signature demonstrates significantly different prognoses and tumor immune landscapes in lung adenocarcinoma.

B7 family ligands and CD28 family receptors have complicated interaction for modulating immune functions. They play a central role in response to immunotherapy and outcome of patients with lung adenocarcinoma (LUAD). Thus, we analyzed B7-CD28 family gene expression profiles in LUAD and generated a signature to predict prognosis and immune host status. B7-CD28 family gene expression profiles and clinical data of LUAD from The Cancer Genome Atlas (TCGA) were analyzed. In the training cohort, prognostic association was assessed and then a prognostic signature was built with stepwise multivariable Cox analysis. The signature was validated by Kaplan-Meier and multivariable Cox analysis in several published gene expression datasets and a Fudan University cohort. Expression of immune cell populations and other immunotherapy predictors was further investigated. In TCGA LUAD cohort, eight B7-CD28 family genes had prognostic association with p values <0.05. Stepwise regression generated a gene signature including two genes, CD28 and CD276. Signature high-risk cases had worse overall survival (OS) and disease-free survival (DFS) in three published gene expression datasets and a Fudan University validation cohort. The B7-CD28 family based signature also significantly stratified OS and DFS in important clinical subsets, including stage I-II and EGFR mutant subsets. Signature high- and low-risk tumor had significantly different expressions of PD-L1 and tumor infiltrating leukocytes. The B7-CD28 family based signature demonstrates significantly different prognoses and tumor immune landscapes in LUAD. Whether it could serve as potential biomarkers for immunotherapy needs further investigation.

Direct and Indirect Associations Between Diabetes and Intraocular Pressure: The Singapore Epidemiology of Eye Diseases Study.

Purpose: The association between diabetes and IOP is controversial; diabetes is associated with thicker central corneal thickness (CCT), and thicker CCT is associated with higher IOP. We therefore aimed to clarify the diabetes-IOP association, considering CCT as a potential mediator. Methods: We included 8636 participants from the Singapore Epidemiology of Eye Diseases (SEED) Study. Associations of diabetes, serum glucose, or HbA1c with IOP were assessed using regressions models, with adjustments for potential confounding factors. Regression-based mediation (path) analyses were further performed to evaluate the indirect effects of diabetes on IOP through the mediator (CCT), in addition to the direct effect of diabetes on IOP. Results: Of the 8636 participants, 2524 (29.23%) had diabetes. Diabetes, higher serum glucose, or HbA1c levels were all associated with higher IOP (all P < 0.01). The effect of diabetes on IOP was partially and minimally mediated through CCT; the proportion of mediating effect of CCT was 11.09% of the total effect of diabetes on IOP. Axial length and spherical equivalent were not mediating variables in the diabetes-IOP association. Findings were consistent across three ethnicity groups. Conclusions: Diabetes or higher long-term hyperglycemia was associated with higher IOP. CCT contributed a small proportion of mediating effect to the total effect of diabetes on IOP. We conclude that high IOP observed in diabetes is mainly due to the direct association of diabetes and IOP, and this finding may have pathophysiologic significance with respect to the risk of glaucoma among persons with diabetes.

Extended Right Thoracic Approach Compared With Limited Left Thoracic Approach for Patients With Middle and Lower Esophageal Squamous Cell Carcinoma: Three-year Survival of a Prospective, Randomized, Open-label Trial.

OBJECTIVE: To investigate whether survival is improved by using the right thoracic approach (extended lymphadenectomy) compared with the left thoracic approach (limited lymphadenectomy) for esophageal cancer. BACKGROUND: The optimal surgical technique for esophageal cancer remains unclear. METHODS: Between May 2010 and July 2012, 300 patients with middle and lower thoracic esophageal carcinoma were randomized to receive esophagectomy through either the right or left thoracic approach. Of these, 286 patients with squamous cell carcinoma determined by postoperative pathology were included in this analysis. Disease-free survival (DFS) and overall survival (OS) were compared between the right (n = 146) and left thoracic groups (n = 140). RESULTS: The median follow-up was 55.9 months [95% confidence interval (CI): 53.1-58.6]. The 3-year DFS rates were 62% and 52% in the right and left thoracic arms, respectively [hazard ratio (HR) 0.709; 95% CI, 0.506-0.995; P = 0.047, log-rank test]. The 3-year OS rates were 74% and 60%, respectively (HR, 0.663; 95% CI, 0.457-0.961; P = 0.029). Subgroup analyses revealed longer DFS in the right thoracic arm (vs left thoracic arm) in patients with lymph node involvement (HR, 0.632; 95% CI, 0.412-0.969, P = 0.034), but not in patients without lymph node involvement (HR, 0.757; 95% CI, 0.434-1.320, P = 0.325), and in patients with R1-2 resection margins (HR, 0.495; 95% CI, 0.290-0.848, P = 0.009), but not R0 margins (HR, 0.944; 95% CI, 0.603-1.477, P = 0.801). CONCLUSIONS: Compared with the left thoracic approach, the right thoracic approach associated with increased DFS and OS in esophageal squamous cell carcinoma patients, particularly in those with lymph node involvement and/or R1-2 resection margins.
