Does voice endorsement by supervisors enhance or constrain voicer's personal initiative? Countervailing effects via feeling pride and feeling envied.

While the previous research has examined antecedents of supervisors' voice endorsement, it has generally overlooked its effects on voicers' affective and behavioral reactions, probably because of the underlying assumption that supervisors' voice endorsement is inherently beneficial and likely to encourage more proactive behaviors in the future. In this research, we offer a theoretical model of the double-edged effects of supervisors' voice endorsement on voicers' subsequent personal initiative. Drawing on cognitive appraisal theory and related research, we proposed that supervisors' voice endorsement prompts two different cognitive appraisal processes in voicers that evoke two distinct emotional experiences-feeling pride and feeling envied-with countervailing effects on voicers' subsequent personal initiative. Specifically, voice endorsement results in voicers not only feeling pride, which enhances their subsequent personal initiative, but also in their feeling envied, which reduces their later personal initiative. Moreover, we extend the cognitive appraisal theory of emotion from a social constructionist approach by incorporating coworker support-an important relational context-as a contingent factor shaping the effects of voice endorsement on feeling pride and feeling envied and on voicers' subsequent personal initiative. The results from two field studies-a weekly experience sampling study with 574 observations from 119 employees and an event-based daily experience sampling study with 787 observations from 180 employees-largely support our theoretical model. This research suggests the importance of considering the perspectives of all the stakeholders in the proactivity triad (i.e., the focal employee, the supervisor, and coworkers) in order to sustain employee proactivity.

[Effects of α1-antitrypsin on motor function in mice with immature brain white matter injury]. / α1-æŠ—èƒ°è›‹ç™½é ¶å¯¹æœªæˆç†Ÿè„‘ç™½è´¨æŸä¼¤å°é¼ è¿åŠ¨åŠŸèƒ½çš„å½±å“.

OBJECTIVES: To investigate the effects of α1-antitrypsin (AAT) on motor function in adult mice with immature brain white matter injury. METHODS: Five-day-old C57BL/6J mice were randomly assigned to the sham surgery group (n=27), hypoxia-ischemia (HI) + saline group (n=27), and HI+AAT group (n=27). The HI white matter injury mouse model was established using HI methods. The HI+AAT group received intraperitoneal injections of AAT (50 mg/kg) 24 hours before HI, immediately after HI, and 72 hours after HI; the HI+saline group received intraperitoneal injections of the same volume of saline at the corresponding time points. Brain T2-weighted magnetic resonance imaging scans were performed at 7 and 55 days after modeling. At 2 months of age, adult mice were evaluated for static, dynamic, and coordination parameters using the Catwalk gait analysis system. RESULTS: Compared to the sham surgery group, mice with HI injury showed high signal intensity on brain T2-weighted magnetic resonance imaging at 7 days after modeling, indicating significant white matter injury. The white matter injury persisted at 55 days after modeling. In comparison to the sham surgery group, the HI+saline group exhibited decreased paw print area, maximum contact area, average pressure, maximum pressure, paw print width, average velocity, body velocity, stride length, swing speed, percentage of gait pattern AA, and percentage of inter-limb coordination (left hind paw → left front paw) (P<0.05). The HI+saline group showed increased inter-paw distance, percentage of gait pattern AB, and percentage of phase lag (left front paw → left hind paw) compared to the sham surgery group (P<0.05). In comparison to the HI+saline group, the HI+AAT group showed increased average velocity, body velocity, stride length, and swing speed (right front paw) (P<0.05). CONCLUSIONS: The mice with immature brain white matter injury may exhibit significant motor dysfunction in adulthood, while the use of AAT can improve some aspects of their motor function.

Lenvatinib combined with sintilimab plus transarterial chemoembolization as first-line treatment for advanced hepatocellular carcinoma.

BACKGROUND: Recently, combination therapy has shown a better trend towards improved tumour response and survival outcomes than monotherapy in patients with hepatocellular carcinoma (HCC). However, research on triple therapy [lenvatinib + sintilimab + transarterial chemoembolization (TACE)] as a first-line treatment for advanced HCC is limited. AIM: To evaluate the safety and efficacy of triple therapy as a first-line treatment for advanced HCC. METHODS: HCC patients with Barcelona Clinic Liver Cancer stage C treated with triple therapy were enrolled. All patients were treated with lenvatinib every day and sintilimab once every 3 wk. Moreover, TACE was performed every 4-6 wk if necessary. The primary outcome of the study was overall survival (OS). The secondary outcomes were the objective response rate (ORR), disease control rate (DCR), and incidence of adverse events. RESULTS: Forty HCC patients who underwent triple therapy were retrospectively analysed from January 2019 to January 2022. With a median follow-up of 8.5 months, the 3-, 6-, and 12-mo OS rates were 100%, 88.5%, and 22.5%, respectively. The ORR and DCR were 45% and 90%, respectively. The median progressive free survival and median OS were not reached. Common complications were observed in 76% of the patients (grade 3, 15%; grade 4, 2.5%). CONCLUSION: Combination therapy comprising lenvatinib, sintilimab and TACE achieved promising outcomes in advanced HCC patients and had manageable effects.

Non-coding RNAs regulating endothelial progenitor cells for venous thrombosis: promising therapy and innovation.

Venous thromboembolism, which includes deep venous thrombosis (DVT) and pulmonary embolism, is the third most common vascular disease in the world and seriously threatens the lives of patients. Currently, the effect of conventional treatments on DVT is limited. Endothelial progenitor cells (EPCs) play an important role in the resolution and recanalization of DVT, but an unfavorable microenvironment reduces EPC function. Non-coding RNAs, especially long non-coding RNAs and microRNAs, play a crucial role in improving the biological function of EPCs. Non-coding RNAs have become clinical biomarkers of diseases and are expected to serve as new targets for disease intervention. A theoretical and experimental basis for the development of new methods for preventing and treating DVT in the clinic will be provided by studies on the role and molecular mechanism of non-coding RNAs regulating EPC function in the occurrence and development of DVT. To summarize, the characteristics of venous thrombosis, the regulatory role of EPCs in venous thrombosis, and the effect of non-coding RNAs regulating EPCs on venous thrombosis are reviewed. This summary serves as a useful reference and theoretical basis for research into the diagnosis, prevention, treatment, and prognosis of venous thrombosis.

Causal relationship between linoleic acid and type 2 diabetes and glycemic traits: a bidirectional Mendelian randomization study.

Objective: To investigate the causal relationships between linoleic acid and type 2 diabetes, and between linoleic acid and glycemic traits in European populations. Methods: This study employed a two-sample Mendelian randomization approach to infer causality between linoleic acid and type 2 diabetes, as well as between linoleic acid and glycemic traits, leveraging genetic variations. Data were sourced from genome-wide association study summary datasets. Random-effects inverse-variance weighted, weighted median, and MR-Egger methods were used for the two-sample Mendelian randomization analyses. Results were presented as odds ratios with a 95% confidence interval. Multiple sensitivity analyses were conducted to assess result robustness. Results: MR findings indicated a correlation between linoleic acid levels and the risk of type 2 diabetes, fasting blood glucose, and glycated hemoglobin (HbA1c), but not with fasting insulin. Specifically: type 2 diabetes (OR: 0.811, 95% CI: 0.688-0.956, P=0.013<0.05),fasting blood glucose (ß_IVW): -0.056, 95% CI: (-0.091,-0.021), P=0.002< 0.0125), glycated hemoglobin (ß_IVW: -0.032, 95% CI: (-0.048,-0.015), P=0.0002< 0.0125) and Fasting insulin (ß_IVW: -0.024, 95% CI: (-0.056,-0.008), P=0.136 >0.05).Reverse MR analyses showed a correlation between type 2 diabetes and reduced levels of linoleic acid (ß_IVW: -0.033, 95% CI: (-0.059,-0.006), P=0.014<0.05). Multiple sensitivity analyses also detected study heterogeneity but found no evidence of horizontal pleiotropy. Conclusion: High levels linoleic acid can reduce the risk of type 2 diabetes, fasting blood glucose, and glycated hemoglobin, but has no significant relation with fasting insulin. Type 2 diabetes can lower linoleic acid levels; however, no significant causal relationship was observed between the three glycemic traits and reduced levels of linoleic acid.

[Pharmacokinetics, pharmacodynamics, and tissue distribution of oral co-loaded puerarin/daidzein mixed micelles in rats].

This study investigated the drug delivery performance of oral co-loaded puerarin(PUE) and daidzein(DAZ) mixed micelles(PUE/DAZ-FS/PMMs) from the perspectives of pharmacokinetics, pharmacodynamics, and tissue distribution. The changes in PUE plasma concentration in rats were evaluated based on PUE suspension, single drug-loaded micelles(PUE-FS/PMMs), and co-loaded micelles(PUE/DAZ-FS/PMMs). Spontaneously hypertensive rats(SHR) were used to monitor systolic blood pressure, diastolic blood pressure, and mean arterial pressure for 10 weeks after administration by tail volume manometry. The content of PUE in the heart, liver, spleen, lung, kidney, brain, and testes was determined using LC-MS/MS. The results showed that compared with PUE suspension and PUE-FS/PMMs, PUE/DAZ-FS/PMMs significantly increased C_(max) in rats(P<0.01) and had a relative bioavailability of 122%. The C_(max), AUC_(0-t), AUC_(0-∞), t_(1/2), and MRT of PUE/DAZ-FS/PMMs were 1.77, 1.22, 1.22, 1.17, and 1.13 times higher than those of PUE suspension, and 1.76, 1.16, 1.08, 0.84, and 0.78 times higher than those of PUE-FS/PMMs, respectively. Compared with the model control group, PUE/DAZ-FS/PMMs significantly reduced systolic blood pressure, diastolic blood pressure, and mean arterial pressure in SHR rats(P<0.05). The antihypertensive effect of PUE/DAZ-FS/PMMs was greater than that of PUE suspension, and even greater than that of PUE-FS/PMMs at high doses. Additionally, the distribution of PMMs in various tissues showed dose dependency. The distribution of PMMs in the kidney and liver, which are metabolically related tissues, was lower than that in the suspension group, while the distribution in the brain was higher than that in the conventional dose group. In conclusion, PUE/DAZ-FS/PMMs not only improved the bioavailability of PUE and synergistically enhanced its therapeutic effect but also prolonged the elimination of the drug to some extent. Furthermore, the micelles facilitated drug penetration through the blood-brain barrier. This study provides a foundation for the development of co-loaded mixed micelles containing homologous components.

Getting under the skin? Influences of work-family experiences on personality trait adaptation and reciprocal relationships.

The literature on personality trait development has mainly focused on influences of life experiences in one single life domain (e.g., work or family) separate from one another and has primarily examined personality development in early life stages. Thus, less attention has been devoted to influences from interplays across different life domains and personality development in middle and late adulthood. Synthesizing the literature on personality science and organizational research, we built a theoretical model and investigated what, how, and why the interplay between two central life domains-work and family-may be related to personality trait development of people at their middle and late life stages, and more important, change-related reciprocal relationships between personality traits and work-family experiences. Generally, convergent findings with data from two longitudinal studies (National Survey of Midlife in the United States, maximum N = 3,192, three waves; and Health and Retirement Study, maximum N = 1,133, three waves except anxiety) revealed that work-to-family conflict, family-to-work conflict, work-to-family facilitation, and family-to-work facilitation mostly had lagged effects on changes of Conscientiousness, Extraversion, and Neuroticism, and the influences were generally channeled through changes of anxiety. Personality traits also had lagged influences on changes of work-family experiences, with some influences deteriorating over time. Change-related reciprocal relationships were recorded mainly between Neuroticism and Extraversion with work-family experiences. Some selection effects were larger than socialization effects. Our research contributes to the personality and the work-family literature and represents a useful example of cross-fertilization of research in different areas of psychology to advance personality research.

The controlling nutritional status score predicts postoperative mortality in patients with ruptured abdominal aortic aneurysm: a retrospective study.

Background: Ruptured abdominal aortic aneurysms (rAAAs) are challenging for vascular surgeons because they have a high mortality rate. In many diseases, nutritional status is closely associated with prognosis. The Controlling Nutritional Status (CONUT) screening tool score is a prognostic factor in some malignant and chronic diseases; however, the impact of nutritional status on rAAA has not yet been reported. In this study, we explored the relationship between the CONUT score and the postoperative prognosis of patients with rAAA. Methods: This was a retrospective review of 39 patients with rAAA who underwent surgical treatment from March 2018 to September 2021 at one center. Patient characteristics, nutritional status (CONUT score), and postoperative status were recorded. The patients were divided into groups A and B based on the CONUT score. The baseline characteristics of the two groups were compared, and Cox proportional hazards and logistic regression analyses were used to determine independent predictors of mid-term mortality and complications, respectively. Results: The overall mid-term mortality rate was 28.21% (11/39). Compared with group A, group B had higher intraoperative (P = 0.047) and mid-term mortality (P = 0.033) rates. The univariate analysis showed that age [hazard ratio (HR), 1.098; 95% confidence interval (CI), 1.019-1.182; P = 0.014], CONUT score (HR, 1.316; 95% CI, 1.027-1.686; P = 0.03), and surgical procedure (HR, 0.127; 95% CI, 0.016-0.992; P = 0.049) were associated with mid-term mortality, whereas the multivariate analysis showed that the CONUT score (HR, 1.313; 95% CI, 1.009-1.710; P = 0.043) was an independent predictor of mid-term mortality. The multivariate logistic regression analysis did not reveal any associations with complications. The Kaplan-Meier curves showed that group B had a lower mid-term survival rate (log-rank P = 0.024). Conclusion: Malnutrition is closely associated with the prognosis of patients with rAAA, and the CONUT score can be used to predict mid-term mortality.

Update on the genetic diversity and population structure of Echinococcus granulosus in Gansu Province, Tibet Autonomous Region, and Xinjiang Uygur Autonomous Region, Western China, inferred from mitochondrial cox1, nad1, and nad5 sequences.

The identification of additional Echinococcus granulosus sensu lato (s.l.) complex species/genotypes in recent years raises the possibility that there might be more variation among this species in China than is currently understood. The aim of this study was to explore intra- and inter-species variation and population structure of Echinococcus species isolated from sheep in three areas of Western China. Of the isolates, 317, 322, and 326 were successfully amplified and sequenced for cox1, nad1, and nad5 genes, respectively. BLAST analysis revealed that the majority of the isolates were E. granulosus s.s., and using the cox1, nad1, and nad5 genes, respectively, 17, 14, and 11 isolates corresponded to Elodea canadensis (genotype G6/G7). In the three study areas, G1 genotypes were the most prevalent. There were 233 mutation sites along with 129 parsimony informative sites. A transition/transversion ratio of 7.5, 8, and 3.25, respectively, for cox1, nad1, and nad5 genes was obtained. Every mitochondrial gene had intraspecific variations, which were represented in a star-like network with a major haplotype with observable mutations from other distant and minor haplotypes. The Tajima's D value was significantly negative in all populations, indicating a substantial divergence from neutrality and supporting the demographic expansion of E. granulosus s.s. in the study areas. The phylogeny inferred by the maximum likelihood (ML) method using nucleotide sequences of cox1-nad1-nad5 further confirmed their identity. The nodes assigned to the G1, G3, and G6 clades as well as the reference sequences utilized had maximal posterior probability values (1.00). In conclusion, our study confirms the existence of a significant major haplotype of E. granulosus s.s. where G1 is the predominant genotype causing of CE in both livestock and humans in China.

Three-Dimensional Printing to Guide Fenestrated/Branched TEVAR in Triple Aortic Arch Branch Reconstruction With a Curative Effect Analysis.

PURPOSE: To summarize experience with and the efficacy of fenestrated/branched thoracic endovascular repair (F/B-TEVAR) using physician-modified stent-grafts (PMSGs) under 3D printing guidance in triple aortic arch branch reconstruction. MATERIALS AND METHODS: From February 2018 to April 2022, 14 cases of aortic arch aneurysms and 30 cases of aortic arch dissection (22 acute aortic arch dissection and 8 long-term aortic arch dissection)were treated by F/B-TEVAR in our department, including 34 males and 10 females, with an average age of 59.84 ± 11.72 years. Three aortic arch branches were affected in all patients. A 3D-printed model was made according to computed tomography angiography images and used to guide the fabrication of PMSGs. All patients were followed up. RESULTS: A total of 132 branches were successfully reconstructed with no case of conversion to open surgery. The average operation time was 4.97 ± 1.40 hours, including a mean 44.05 ± 7.72 minutes for stent-graft customization, the mean postoperative hospitalization duration was 9.91 ± 4.47 days, the average intraoperative blood loss was 480.91 mL (100-2810 mL), and the mean postoperative intensive care unit monitoring duration was 1.02 days (0-5 days). No deaths occurred within 30 days of surgery. Postoperative neurological complications occurred in 1 case (2.3%), and retrograde type A dissection occurred in 1 case (2.3%). CONCLUSION: Compared with conventional surgery, triple aortic arch branch reconstruction under the guidance of 3D printing is a minimally invasive treatment method with the advantages of accurate positioning, rapid postoperative recovery, few complications, and reliable short- to mid-term effects. CLINICAL IMPACT: At present the PMSG usually depend on imaging data and software calculation. With the guidance of 3D printing technology, image data could be transformed into 3D model, which has improved the accuracy of the positioning of the fenestrations. The diameter reduction technique and the internal mini cuff technique have made a complement to the slimed-down fenestration selection process and the low rate of endoleak. As reproducible study, our results may provide reference for TEVAR in different cases.

3D Printing-guided endovascular repair of enormous twisted thoracoabdominal aortic aneurysm with branch stenosis and occlusion.

A 67-year-old male patient was admitted with an enormous twisted thoracoabdominal aortic aneurysm (TAAA) with multiple branch arteries stenosis and occlusion. Three-dimensional (3D) printing technology combined with mechanics was used for developing a transparent model of lesion to simulate the segment of diseased aorta. A stent graft was deployed in the 3D model to make a physician-modified stent graft (PMSGs) on table. The locations of the opening of branches were marked twice during operation. The PMSG was successfully deployed during the surgery and repaired the TAAA, with no endoleak and all the branched arteries patency in follow-up. This technique could offer precision individualized therapy and could simplify the procedure process greatly.

Transarterial chemoembolization combined with radiofrequency ablation in the treatment of large hepatocellular carcinoma with stage C.

BACKGROUND: The combination therapy of transarterial chemoembolization and radiofrequency ablation (TACE-RFA) shows promising efficacy in large hepatocellular carcinoma (HCC). Data on the clinical efficacy and safety of TACE-RFA for large HCC with barcelona clinic liver cancer (BCLC) stage C are lacking in China. AIM: To determine the safety and efficacy of TACE-RFA for large, advanced HCC. METHODS: Patients of HCC with BCLC stage C who were treated with TACE-RFA or TACE alone at our institute from August 2008 to January 2017 were retrospectively reviewed. The complications were observed. The associations between overall survival (OS) and treatment method were analysed. RESULTS: Data were collected from 102 HCC patients. Among them, 64 underwent TACE-RFA and 38 underwent TACE. The combination of TACE and RFA was safe. All complications were controllable. The median OS in the TACE-RFA group was significantly longer than that in the TACE group (8.0 mo vs 4.0 mo, P = 0.000). The 6-, 12- and 24-mo survival rates of the combination group were 68.8%, 34.4%, and 10.9%, respectively, while those of the TACE group were 36.8%, 7.9%, and 0% (P < 0.05). CONCLUSION: TACE-RFA has an advantage over TACE alone in improving OS in large HCC patients with BCLC stage C.

Case report: Remedial surgical treatment of aorto-duodenal fistula with infected aneurysm after endovascular aortic repair.

Aorto-duodenal fistula (ADF) is a rare cause of upper gastrointestinal bleeding, but it is associated with high mortality. It usually occurs in patients with prior aortic surgery or who have undergone aortic graft placement. Abdominal aortic aneurysm (AAA) might be a cause of primary ADF, which could develop into sudden shock. Because ADF is difficult to diagnose, surgery to correct it has a poor outcome. We here report the successful treatment of an ADF complicated with infected AAA after endovascular repair of a ruptured aneurysm of the iliac artery.

CT-guided percutaneous chemical ablation combined with radiofrequency ablation for hepatocellular carcinomas in high-risk locations: lobaplatin vs. ethanol.

To retrospectively compare the clinical efficacy and safety of CT-guided percutaneous injection of lobaplatin vs. ethanol for chemical ablation combined with radiofrequency ablation (RFA) in patients with hepatocellular carcinomas (HCCs) in high-risk locations. From January 2017 to June 2018, a total of 41 patients with HCCs in high-risk locations were enrolled and divided into two groups: percutaneous lobaplatin injection (PLI+RFA) group and percutaneous ethanol injection (PEI+RFA) group. The mixture of lobaplatin or ethanol was accurately injected into the high-risk part of the tumors, while RFA ablated the non-high-risk part. The efficacy and safety were compared between the two groups. 41 patients had 51 lesions in high-risk locations, including 24 cases with 30 lesions in PLI+RFA group and 17 cases with 21 lesions in PEI+RFA group. The complete ablation rate was 93.3% (28/30) in PLI+RFA group and 90.5% (19/21) in PEI+RFA group (P=1.000). The 2-year local tumor progression rate of PLI+RFA group and PEI+RFA group was 20.0% (6/30) and 19.0% (4/21), respectively (P=1.000). No significant differences were found in time to progression and overall survival between the two groups (P=0.501 and P=0.424, respectively). The incidence and severity of adverse events between the two groups were similar (P > 0.05). No severe complications were observed in both groups. Percutaneous lobaplatin injection combined with RFA in the treatment of HCC in high-risk locations may achieve the complete ablation rate similar to percutaneous ethanol injection combined with RFA, but further research is needed to confirm.

The regulatory role of exosomes in venous thromboembolism.

Exosomes are nanoscale endocytic vesicles, 30-150 nm in diameter, secreted by most cells. They mainly originate from multivesicular bodies formed by intracellular invagination of lysosomal microparticles, and released into the extracellular matrix after fusion of multivesicular bodies with cell membrane. Studies have shown that exosomes contain a variety of active molecules, such as proteins, lipids and RNAs (such as mRNA, miRNA, lncRNA, circRNA, etc.), which regulate the behavior of recipient cells and serve as circulating biomarkers of diseases, including thrombosis. Therefore, exosome research is important for the diagnosis, treatment, therapeutic monitoring, and prognosis of thrombosis in that it can reveal the counts, surface marker expression, protein, and miRNA cargo involved. Recent studies have shown that exosomes can be used as therapeutic vectors for tissue regeneration and as alternative vectors for drug delivery. In this review, we summarize the physiological and biochemical characteristics, isolation, and identification of exosomes. Moreover, we focus on the role of exosomes in thrombosis, specifically venous thromboembolism, and their potential clinical applications, including as biomarkers and therapeutic vectors for thrombosis.

[Establishment of a predictive nomogram model for predicting the death of very preterm infants during hospitalization]. / 极早产儿住院期间死亡的列线图预测模型的建立.

OBJECTIVES: To establish a nomogram model for predicting the risk of death of very preterm infants during hospitalization. METHODS: A retrospective analysis was performed on the medical data of 1 714 very preterm infants who were admitted to the Department of Neonatology, the Third Affiliated Hospital of Zhengzhou University, from January 2015 to December 2019. These infants were randomly divided into a training cohort (1 179 infants) and a validation cohort (535 infants) at a ratio of 7∶3. The logistic regression analysis was used to screen out independent predictive factors and establish a nomogram model, and the feasibility of the nomogram model was assessed by the validation set. The area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA) were used to assess the discriminatory ability, accuracy, and clinical applicability of the model. RESULTS: Among the 1 714 very preterm infants, 260 died and 1 454 survived during hospitalization. By the multivariate logistic regression analysis of the training set, 8 variables including gestational age <28 weeks, birth weight <1 000 g, severe asphyxia, severe intraventricular hemorrhage (IVH), grade III-IV respiratory distress syndrome (RDS), and sepsis, cesarean section, and use of prenatal glucocorticoids were selected and a nomogram model for predicting the risk of death during hospitalization was established. In the training cohort, the nomogram model had an AUC of 0.790 (95%CI: 0.751-0.828) in predicting the death of very preterm infants during hospitalization, while in the validation cohort, it had an AUC of 0.808 (95%CI: 0.754-0.861). The Hosmer-Lemeshow goodness-of-fit test showed a good fit (P>0.05). DCA results showed a high net benefit of clinical intervention in very preterm infants when the threshold probability was 10%-60% for the training cohort and 10%-70% for the validation cohort. CONCLUSIONS: A nomogram model for predicting the risk of death during hospitalization has been established and validated in very preterm infants, which can help clinicians predict the probability of death during hospitalization in these infants.

Genetic basis of job attainment characteristics and the genetic sharing with other SES indices and well-being.

Job attainment is an important component of socioeconomic status (SES). There is currently a paucity of genomic research on an individual's job attainment, as well as how it is related to other SES variables and overall well-being at the whole genome level. By incorporating O*NET occupational information into the UK Biobank database, we performed GWAS analyses of six major job attainment characteristics-job complexity, autonomy, innovation, information demands, emotional demands, and physical demands-on 219,483 individuals of European ancestry. The job attainment characteristics had moderate to high pairwise genetic correlations, manifested by three latent factors: cognitive, emotional, and physical requirements. The latent factor of overall job requirement underlying the job attainment traits represented a critical genetic path from educational attainment to income (P < 0.001). Job attainment characteristics were genetically positively correlated with positive health and well-being outcomes (i.e., subject well-being, overall health rating, number of non-cancer illnesses etc. (|rg|: 0.14-0.51), similar to other SES indices; however, the genetic correlations exhibited opposite directions for physical demands (|rg|: 0.14-0.51) and were largely negligible for emotional demands. By adopting a finer-grained approach to capture specific job attainment phenotypes, our study represents an important step forward in understanding the shared genetic architecture among job attainment characteristics, other SES indices, and potential role in health and well-being outcomes.

Genetics, leadership position, and well-being: An investigation with a large-scale GWAS.

SignificanceOur study presents the largest whole-genome investigation of leadership phenotypes to date. We identified genome-wide significant loci for leadership phenotypes, which are overlapped with top hits for bipolar disorder, schizophrenia, and intelligence. Our study demonstrated the polygenetic nature of leadership, the positive genetic correlations between leadership traits and a broad range of well-being indicators, and the unique association of leadership with well-being after accounting for genetic influences related to other socioeconomic status measures. Our findings offer insights into the biological underpinnings of leadership.

[Clinical features of very preterm infants with prelabor rupture of membranes and predictive factors for major adverse outcomes].

OBJECTIVE: To study the clinical features of very preterm infants with prelabor rupture of membranes (PROM) and predictive factors for early-onset sepsis (EOS) and death. METHODS: A retrospective analysis was performed for the clinical data of the very preterm infants with PROM (with a gestational age of < 32 weeks) who were admitted to the neonatal intensive care unit from January 2018 to May 2020. According to the time from membrane rupture to delivery, the infants were divided into four groups: < 18 hours (n=107), 18 hours to < 3 days (n=111), 3 days to < 14 days (n=144), and ≥ 14 days (n=37). According to the presence or absence of EOS, the infants were divided into EOS (n=42) and non-EOS groups (n=357). According to the survival state, the infants were divided into a survival group (n=359) and a death group (n=40). Clinical features were analyzed for very preterm infants with different times of PROM. A multivariate logistic regression analysis was used to investigate the predictive factors for EOS and death in very preterm infants with PROM. RESULTS: There was no significant difference in the incidence rates of major neonatal complications and mortality rate among the very preterm infants with different times of PROM (P > 0.05). Birth weight < 1 000 g (OR=4.353, P=0.042), grade Ⅲ amniotic fluid contamination (OR=4.132, P=0.032), and grade Ⅲ-Ⅳ respiratory distress syndrome (RDS) (OR=2.528, P=0.021) were predictive factors for EOS in very preterm infants with PROM. Lower birth weights (< 1 000 g or 1 000-1 499 g; OR=11.267 and 3.456 respectively; P=0.004 and 0.050 respectively), grade Ⅲ-Ⅳ RDS (OR=5.572, P < 0.001), and neonatal sepsis (OR=2.631, P=0.012) were predictive factors for death in very preterm infants with PROM. CONCLUSIONS: Prolonged PROM does not increase the incidence of neonatal complications and mortality in very preterm infants. Adverse outcomes of very preterm infants with PROM are mainly associated with lower birth weights, lung immaturity, and systemic infection.
