Despite the prevalence of teams in research, there is a lack of a good understanding of how their size and diversity affects their performance. We develop a theoretical framework that distinguishes two dimensions of research performance for an academic paper: impact (i.e., subsequent citations) and prestige (i.e., ranking of the journal where research is published). We propose that, while larger teams will enhance linearly the impact of research, they will affect its prestige in a nonlinear fashion. We further contend that these effects will be moderated by knowledge and international diversity of the teams. We test these hypotheses using bibliometric data between 1990 and 2020 on more than 1.4 million papers and 18 million citation counts across 22 subfields in management. Our results confirm significant benefits for research impact from both team size and diversity, but also highlight drawbacks when teams become very large and heterogeneous. Moreover, we find a nonlinear positive effect of team size on research prestige that can be offset only by high levels of knowledge diversity. These findings are robust to a variety of proxies, controls, and estimation techniques, including instrumental variables and propensity score matching. We discuss practical implications for stimulating research performance in business schools. [ABSTRACT FROM AUTHOR]

This paper investigates how investments in automation affect the gender pay gap. The evidence of the effects of automation on the labor market is growing; however, little is known about the implications of automation for the gender pay gap. The data used in this paper are from a matched employer–employee dataset incorporating detailed information on firms, their imports, and employee–level data for Estonian manufacturing and service employers for the period of 2006–2018. Through the use of the imports of automation goods as a proxy for the introduction of automation at the firm level, this paper estimates the effect of automation using simple Mincerian wage equations. The causality of the effect is further validated using propensity score matching (PSM). We find that introducing automation enlarges the gender pay gap, and PSM confirms that this also has a higher causal effect on the wages of male employees than female employees. The results imply that a higher representation of women in higher-paid positions does not guarantee a reduction in the gender pay gap in the presence of automation, and appropriate measures in education and retraining are needed to tackle the effect of automation on gender inequality.

This study investigates the relationship between corporate site visits (CSVs) and firms' real earnings management. Using a unique dataset of site visits to Chinese firms listed on the Shenzhen Stock Exchange from 2009 to 2016, we find that such visits are negatively associated with firms' real earnings management. The results are robust to using alternative CSV measures, controlling for alternative communication channels, and using the propensity score matching method. In cross-sectional analyses, we find that the negative association between site visits and real earnings management is stronger for more complex firms and firms with greater information asymmetry. In addition, we find that CSVs are negatively associated with both management and corporate misconduct but not with accrual-based earnings management or restatements. [ABSTRACT FROM AUTHOR]

Background: Creating activity-friendly communities (AFCs) is an important strategy to increase physical activity (PA). While cross-sectional links between community environments and PA are well documented, their causal relationships remain insufficiently explored. Methods: Using the accelerometer and survey data collected from adults who moved to an AFC (cases) and similar non-AFC-residing adults who did not move (comparisons), this pre–post, case-comparison study examines if moving to an AFC increases PA. Data came from 115 participants (cases = 37, comparisons = 78) from Austin, Texas, who completed 2 waves of 1-weeklong data collection. Difference-in-difference analyses and fixed-effect models were used to test the significance of the pre–post differences in moderate-to-vigorous PA (MVPA) between cases and comparisons, for the full sample and the subsample of 37 pairs matched in key covariates using the Propensity Score Matching method. Results: Average treatment effect generated based on Propensity Score Matching and difference-in-difference showed that moving to this AFC led to an average of 10.88 additional minutes of daily MVPA (76.16 weekly minutes, P =.015). Fixed-effect models echoed the result with an increase of 10.39 minutes of daily MVPA after moving to the AFC. We also found that case participants who were less active at baseline and had higher income increased their MVPA more than their counterparts. Conclusions: This study showed that, among our study sample, moving to an AFC increased residents' PA significantly when compared to their premove level and the comparison group. This causal evidence suggests the potential of AFCs as sustainable interventions for PA promotion. [ABSTRACT FROM AUTHOR]

This paper investigates the impact of China's bilateral currency swap agreements (BSAs) on bilateral direct investments (BDIs). We treat signing China's BSAs as a quasi-natural experiment and employ the gravity model with a staggered difference-in-differences (DID) method to explore the relationship between signing China's BSAs and BDIs. Our empirical results suggest that signing China's BSAs and increasing their value can effectively boost BDIs. The findings remain robust after utilizing the propensity score matching DID (PSM-DID) method, the instrumental variable method, adding additional explanatory variables, and eliminating interference from critical events. In addition, we find that the impact of China's BSAs on BDIs varies significantly depending on partner country features, such as level of development, whether to sign the Belt and Road Initiative (BRI), trade relations with China, and the degree of capital account openness. Moreover, the governance quality in the host country has a positive moderating effect on the impact of China's BSAs on the country's FDI. Our study has vital policy implications for governments worldwide that have signed China's BSAs and those that want to promote BDIs by signing China's BSAs. [ABSTRACT FROM AUTHOR]

Summary: Background: Optimal glycaemic control has well‐established health benefits in patients with diabetes mellitus (DM). It is uncertain whether optimal glycaemic control can benefit liver‐related outcomes. Aims: To examine the association of optimal glycaemic control with hepatocellular carcinoma (HCC) and liver‐related mortality. Methods: In a population‐based cohort, we identified patients with newly diagnosed DM between 2001 and 2016 in Hong Kong. Optimal glycaemic control was defined as mean haemoglobin A1c (HbA1c) <7% during the 3‐year lead‐in period after DM diagnosis. By applying propensity score matching to balance covariates, we analysed glycaemic control via competing risk models with outcomes of interest being HCC and liver‐related mortality. Results: We identified 146,430 patients (52.2% males, mean age 61.4 ± 11.8 years). During a median follow‐up duration of 7.0 years, 1099 (0.8%) and 978 (0.7%) patients developed HCC and liver‐related deaths. Optimal glycaemic control, when compared to suboptimal glycaemic control, was associated with reduced risk of HCC (subdistribution hazard ratio [SHR] 0.70, 95% CI 0.61–0.79). The risk of HCC increased with incremental HbA1c increases beyond >7% (SHR 1.29–1.71). Significant associations with HCC were also found irrespective of age (SHR 0.54–0.80), sex (SHR 0.68–0.69), BMI <25 or ≥25 kg/m2 (SHR 0.63–0.75), smoking (SHR 0.61–0.72), hepatic steatosis (SHR 0.67–0.68) and aspirin/statin/metformin use (SHR 0.67–0.75). A lower risk of liver‐related mortality in relation to optimal glycaemic control was also observed (SHR 0.70, 95% CI 0.61–0.80). Conclusions: Glycaemic control is an independent risk factor for HCC and liver‐related mortality, and should be incorporated into oncoprotective strategies in the general DM population.

This study aimed to compare the efficacy and safety of combining first-line chemoimmunotherapy with radiation therapy versus chemoimmunotherapy alone in patients with stage IVB esophageal squamous cell carcinoma (ESCC). We retrospectively examined 409 patients with stage IVB ESCC who received first-line chemotherapy and anti-PD-1 antibody, with or without radiation therapy of ≥40 Gy radiation dose to primary lesion, from 4 academic cancer centers between October 2018 and December 2022. Propensity score matching was conducted to minimize the potential confounding effects. In the overall cohort of 409 patients, the group that received additional radiation therapy had superior overall survival (OS) (hazard ratio [HR], 0.51; 95% CI, 0.39-0.66; P <.001) and progression-free survival (PFS) (HR, 0.52; 95% CI, 0.40-0.66; P <.001) compared to the group that received chemoimmunotherapy alone. After 1:1 propensity score matching, matching age, tumor location, and metastatic sites, a total of 250 patients were selected for further analysis. The results remained consistent and showed that the addition of radiation therapy significantly improved OS and PFS (median OS, 24.9 vs 14.6 months; P =.003; median PFS, 14.2 vs 10.6 months; P =.002). Multivariate Cox analysis including tumor location, T stage, metastatic sites, and treatment modality, revealed that radiation therapy was an independent prognostic factor for both OS (HR, 0.57; 95% CI, 0.41-0.81) and PFS (HR, 0.63, 95% CI, 0.47-0.86). Subgroup analyses revealed significant OS prolongation in patients with nonregional lymph node metastases only who received radiation therapy (HR, 0.49; 95% CI, 0.34-0.70). No OS survival benefit was observed in those with distant organ metastases (HR, 0.72; 95% CI, 0.46-1.13). Regarding safety, the group receiving additional radiation therapy had higher incidences of grade 3 to 4 lymphopenia (74.4% vs 17.7%, P <.001) and esophagitis (11.2% vs 2.4%, P =.006). The addition of radiation therapy to chemoimmunotherapy improved the survival of stage IVB ESCC patients with nonregional lymph node metastasis. [ABSTRACT FROM AUTHOR]

A before and after study framework measures the outcomes in a group of participants before introducing an intervention, and then again afterward. In this study, a before and after study framework is adopted to evaluate the effectiveness of transportation policies and emerging technologies. Generally, the outcome of every before and after study will help decision-makers to monitor and understand the effects of interventions and to make sound decisions. However, many factors such as seasonal factors, holidays, and lane closures might interfere with the evaluation process by inducing variation in traffic volume during the before and after periods. In practice, limited effort has been made to eliminate the effects of these factors. In this study, an extreme gradient boosting (XGBoost)-based propensity score matching (PSM) method is proposed to reduce the biases caused by traffic volume variation during the before and after periods. In order to evaluate the effectiveness of the proposed method, a corridor in the City of Chandler, Arizona where an advanced traffic signal control system has been recently implemented was selected. The results indicated that the proposed method can effectively eliminate the variation in traffic volume caused by the COVID-19 during the evaluation process. In addition, the results of the t-test and Kolmogorov-Smirnov (KS) test demonstrated that the proposed method outperforms other state-of-the-art PSM methods. The application of the proposed method is also transferrable to other before and after evaluation studies and can significantly assist transportation engineers to eliminate the impacts of traffic volume variation on the evaluation process.

Background: Colorectal cancer (CRC) is a major global health concern, with a rising incidence in young individuals. Early-onset CRC displays unique clinicopathological and molecular characteristics, necessitating a closer examination of prognosis, particularly in the context of adjuvant chemotherapy. This study aimed to investigate the prognosis of early-onset CRC patients (< 50 years) diagnosed at stage II/III compared to older counterparts, utilizing propensity score matching to minimize heterogeneity. Methods: A retrospective analysis of 3324 stage II/III CRC patients aged < 70 years was conducted, focusing on age-based subgroups (< 50 vs. ≥ 50 years). Propensity score matching balanced clinical characteristics. Relapse-free survival (RFS) and overall survival (OS) were analyzed. Results: In stage II CRC, age of onset did not impact prognosis after adjuvant chemotherapy, with no significant differences in RFS (5-year RFS rates: 80% in both groups, p = 0.98) and OS (5-year OS rates: 96% vs. 92%, p = 0.17). In stage III, a trend suggested slightly poorer OS in patients aged < 50 years than those ≥ 50 years (5-year OS rates: 85% vs. 88%, p = 0.077). However, in a propensity score-matched cohort, age-dependent differences were attenuated (5-year OS rates: 85% vs. 88%, p = 0.32). Conclusion: In the context of stage II/III CRC patients receiving adjuvant chemotherapy, age was not an independent predictor of prognosis. Age alone should not be the sole factor guiding treatment decisions. [ABSTRACT FROM AUTHOR]

Since the turn of the millennium, levels of recidivism following a prison term have declined in Sweden. The composition of the inmate population has changed, which provides a partial explanation. This study examines whether prison service interventions, such as the provision of treatment, education, and work, might have contributed to the decline in recidivism. The study sample comprises women and men who were released from Swedish prisons between 2012 and 2015. Data have been collected from the Prison and Probation Service registers and the Convictions Register. The analysis employs propensity score matching and regression analysis. The results show that the interventions examined have a positive effect on reducing recidivism, but that their explanatory power is limited. [ABSTRACT FROM AUTHOR]

Purpose: Surgical manipulation of the lungs increases the number of circulating tumor cells and the subsequent risk of metastasis in patients with lung cancer. This study investigated whether or not ligating the tumor-draining pulmonary vein first during lobectomy could improve the prognosis of these patients. Methods: We retrospectively evaluated patients who underwent curative lobectomy for solitary nonsmall-cell lung carcinoma between January 2012 and December 2016. We divided the patients into the vein-first group, in which all associated pulmonary veins were dissected and severed before cutting the pulmonary artery, bronchus, or pulmonary fissure, and the other procedure group. Results: Overall, we included 177 and 413 patients in the vein-first and other procedure groups, respectively. Propensity score matching yielded 67 pairs of patients. The 5-year overall survival (85.6% [95% confidence interval, 77.3–94.8%] vs. 69.4% [58.7–81.9%], P = 0.03%) and recurrence-free survival (73.4% [63.3–85.1%] vs. 53.5% [42.5–67.3%], P = 0.02) were significantly better in the vein-first group than in the other procedure group. The cumulative recurrence rate at 5 years post-surgery was significantly lower in the vein-first group than in the other procedure group (21.7% vs. 38.3%, P = 0.04). Conclusion: Our study suggests that ligating the pulmonary vein first during lobectomy for lung cancer can improve the overall survival, recurrence-free survival, and cumulative recurrence rate.

Introduction: International guidelines recommend definitive combination antibiotic therapy for the management of serious infections involving carbapenem-resistant Acinetobacter (CRAB) species. The commonly available combination options include high-dose sulbactam, polymyxins, tetracyclines, and cefiderocol. Scanty prospective data exist to support this approach. Methods: Patients with CRAB bacteraemia, ventilator-associated pneumonia (VAP), or both were categorized based on whether they received combination therapy or monotherapy. The 30-day mortality was compared between the two groups. Inverse probability treatment weighting (IPTW) was done using propensity score (PS) for a balanced comparison between groups. Results: Between January 2021 and May 2023, of the 161 patients with CRAB bacteraemia (n = 55, 34.2%), VAP (n = 46, 28.6%), or both (n = 60, 37.3%) who received appropriate intravenous antibiotic therapy, 70% (112/161) received monotherapy, and the rest received combination therapy. The overall 30-day mortality was 62% (99/161) and not different (p = 0.76) between the combination therapy (31/49, 63.3%) and monotherapy (68/112, 60.7%) groups. The propensity score matching using IPTW did not show a statistical difference (p = 0.47) in 30-day mortality for receiving combination therapy with an adjusted odds ratio (OR) P of 1.29 (0.64, 2.58). Conclusion: Combination therapy for CRAB infections needs further study in a randomised controlled trial, as this observational study showed no difference in 30-day mortality between monotherapy and combination therapy.

Comparisons between single-sex (SS) and coeducational (CE) schools are often limited in design. Associations between SS schooling and gender cognitions remain especially unclear. We compared gender cognitions in students from SS versus CE high schools. A longitudinal design addressed long-term reciprocal effects, and propensity score matching addressed preexisting (confounding) differences between SS and CE students. During the final year of high school (N = 667) and again following graduation (N = 463), students completed measures of gender salience, gender stereotypes, felt pressure for gender conformity, and exposure to gender equality. Before graduation, SS students were more gender salient about self, reported more exposure to gender equality, and had less pressure for gender conformity. The magnitudes of these SS–CE differences were small but did not change significantly over time. However, gender salience about self did not predict or mediate other gender cognitions as often hypothesized, and there were no differences in gender salience about others or in gender stereotypes. We conclude that SS schooling is related to some gender-related cognitions both prior to and following high school graduation. However, findings are neither consistently supportive nor critical of either type of schooling. SS schooling was positively related to students' attention to their own gender, but how this attention relates to other gender cognitions may vary across individuals in ways that need further research. Our design innovations and inclusion of debated yet understudied outcomes contribute to a fuller evaluation of SS versus CE schooling by examining long-term development and by expanding the outcomes evaluated. Educational Impact and Implications Statement: We employed a novel rigorous design that followed students longitudinally before and after their high school graduation and examined understudied outcomes (i.e., gender cognitions) to evaluate single-sex versus coeducational schooling more fully. Single-sex, compared to coeducational, high school students are slightly more conscious of their gender but are no more or are less gender-typed in some other gender cognitions. High school students' gender cognitions undergo temporal changes regardless of school type. [ABSTRACT FROM AUTHOR]

Background and Aims: The impact of hepatitis C virus (HCV) eradication via direct‐acting antiviral (DAA) therapy on overall mortality, particularly non‐liver‐related mortality, is understudied. Methods: We recruited 4180 patients with chronic HCV infection who achieved sustained virological response (SVR) (HCV eradication) through DAA therapy (n = 2501, SVR group) or who did not receive antiviral therapy (n = 1679, non‐SVR group); 1236 from each group were chosen using propensity score matching. Causes of death and all‐cause mortality, including non‐liver‐related diseases, were investigated. Results: Of the 4180 patients, 592 died during the follow‐up period. In the SVR group, the mortality rates from liver‐related and non‐liver‐related diseases were 16.5% and 83.5%, respectively. Compared to the non‐SVR group, mortality rates from liver‐related and non‐liver‐related diseases were 50.1% and 49.9%, respectively (p <.001). In non‐cirrhotic patients, multivariable analysis revealed that SVR was an independent factor associated with both liver‐related (hazard ratio [HR],.251; 95% confidence interval [CI],.092–.686) and non‐liver‐related (HR,.641; 95% CI,.415–.990) mortalities. In cirrhotic patients, multivariable analysis revealed that SVR remained an independent factor significantly associated with liver‐related mortality (HR,.151; 95% CI,.081–.279). In propensity score‐matched patients, the eradication of HCV (SVR group) decreased both liver‐related (p <.001) and non‐liver‐related mortality (p =.008) rates compared to persistent HCV infection (non‐SVR group). Conclusions: The elimination of HCV via DAA therapy reduced not only liver‐related mortality but also non‐liver‐related mortality in patients with chronic HCV. [ABSTRACT FROM AUTHOR]

Cost-effectiveness of Robotic-assisted hepatectomy compared to the open approach is scrutinized. We compared the costs of robotic versus open hepatectomy at a large cancer center. Patients undergoing hepatectomy (1/2019-2/2022) were collected from a prospectively maintained database and 1:1 propensity score matched for 61 robotic and 61 open hepatectomy patients by complexity, tumor diagnosis, and age >65. Financial data was collected and converted to a ratio of service cost to average OR cost. Short-term and economic outcomes were compared. Median length of stay (2 vs. 3 days), major complication rates (0% vs. 8.2%), and 90-day readmission rates (3.3% vs. 11.5%) were lower for robotic hepatectomy (all p < 0.05). Total 90-day perioperative costs were lower by 19.5% for the robotic cohort (mean 6.89 vs 8.56; p < 0.01). Intraoperative costs were higher in the robotic cohort (mean 2.75 vs. 2.44; p < 0.01). Cost reduction drivers during postoperative care were supplies (mean 0.26 vs. 0.75), laboratory (mean 0.27 vs. 0.49), regular surgery unit (mean 0.19 vs. 0.32), recovery room (mean 0.26 vs. 0.29) and pharmacy cost (median 0.21 vs. 0.32; all p < 0.05). Hospital costs of robotic hepatectomy were lower than those of open hepatectomy due to significantly reduced postoperative costs. [Display omitted] [ABSTRACT FROM AUTHOR]

Background: The role of viral agents in the development of head and neck cancers has remained controversial. While markers of viral origin have been isolated from oral cancer tissues, a causative relationship has yet to be shown. The aim of this study was to evaluate the relationship between head and neck cancers and Herpes simplex virus, one of the most common viral infections of the oral orifice. Methods: Here, we conducted a retrospective analysis of two age‐ and gender‐matched cohorts extracted from the real‐world database TriNetX on March 10th, 2023, each consisting of 249,272 patients with and without Herpes simplex infections (ICD‐10: B00). The diagnoses C00‐C14 were analyzed, and risk analysis and Kaplan‐Meier survival statics were computed. Results: The strongest association was found for lip cancer (ICD‐10: C00) with a hazard ratio [HR (CI 95% low‐high)] of 3.08 (1.77–5.35). A significant association with HR of 1.17 (1.02–1.34) was found for the entire group of head and neck cancers. Confounders like smoking and alcohol dependence were considered using propensity score matching. Conclusion: The surprisingly strong correlation with lip, oral cavity, and pharynx neoplasms sheds new light on supposedly harmless herpes simplex infections, suggesting them as a possible new factor for risk stratification.

Background: Spinal cord lesions in multiple sclerosis (MS) have considerable impact on disability. High-efficacy disease-modifying treatments (hDMTs) are associated with greater reduction of relapses and new brain lesions compared to low-efficacy treatments (lDMTs). Knowledge on the impact of DMTs on cord lesion formation is limited as these outcome measures were not included in MS treatment trials. This study aims to investigate whether hDMTs reduce the formation of cord lesions more effectively than lDMTs. Methods: Patients with relapse-onset MS, a cord magnetic resonance imaging (MRI) within 6 months before/after initiation of their first DMT and ≥1 cord MRI at follow-up (interval > 6 months) were extracted from the MSBase registry (ACTRN12605000455662). Patients treated with hDMTs ≥90% or lDMTs ≥90% of follow-up duration were considered the hDMT and lDMT groups, respectively. Matching was performed using propensity scores. Cox proportional hazards models were used to estimate the hazards of new cord lesions, brain lesions and relapses. Results: Ninety-four and 783 satisfied hDMT and lDMT group criteria, respectively. Seventy-seven hDMT patients were matched to 184 lDMT patients. In the hDMT group there was no evidence of reduction of new cord lesions (hazard ratio [HR] 0.99 [95% CI 0.51, 1.92], p = 0.97), while there were fewer new brain lesions (HR 0.22 [95% CI 0.10, 0.49], p < 0.001) and fewer relapses (HR 0.45 [95% CI 0.28, 0.72], p = 0.004). Conclusion: A potential discrepancy exists in the effect of hDMTs over lDMTs in preventing spinal cord lesions versus brain lesions and relapses. While hDMTs provided a significant reduction for the latter when compared to lDMTs, there was no significant reduction in new spinal cord lesions. [ABSTRACT FROM AUTHOR]

Background: There is interest in using bladder-preserving therapy as an alternative definitive therapy for muscle invasive bladder cancer in certain high-risk groups such as the elderly. Objective: To determine if bladder-preserving therapy represents a safer alternative to surgical intervention in elderly patients with muscle invasive bladder cancer. Methods: We surveyed the Surveillance, Epidemiology and End Results database (SEER) for cases of non-metastasized malignant bladder cancer in patients aged 80+. Survival outcomes with radical cystectomy (RC) with or without chemotherapy were compared to those after chemotherapy and radiation without cystectomy. We performed log-rank tests and Kaplan-Meier and cox regression and hazard analyses before and after propensity score matching. Results: A total of 2995 patients were identified, with 49.98% treated with RC only, 8.65% treated with RC/chemotherapy, and 41.37% treated with chemotherapy and radiation without RC. Median overall survival for the RC only, RC/chemotherapy and chemotherapy/radiation groups were 31.4, 44.1, and 24.6 months, respectively. On multivariate analysis, hazard ratios (reference: RC/chemotherapy group) were RC Only (HR = 1.408 (95% CI 1.188–1.669), p < 0.0001) and chemotherapy/radiation (HR = 1.650 (95% CI 1.390–1.959), p < 0.0001). After matching the chemotherapy/radiation and RC/chemotherapy groups, the former continued to show survival hazard (HR = 1.744 (95% CI 1.414–2.155), p < 0.0001). Conclusions: Octogenarians should be offered definitive local therapy for their localized bladder cancer including RC and chemotherapy. Bladder-sparing alternatives should be reserved for patients unfit for surgery. [ABSTRACT FROM AUTHOR]

• Patients with PD with constipation had more serious motor and non-motor symptoms. • Emotional and cognitive impairments are related to constipation in patients with PD. • PD patients with constipation have abnormal brain functional activity & connectivity. • Insula and orbitofrontal cortex are involved in the regulation of constipation in PD. Constipation frequently occurs in patients with Parkinson's disease (PD) and may be related to cognitive and emotional disorders. The aim of this study is to investigate the clinical and brain functional characteristics of patients with PD presenting with constipation. The motor and non-motor symptoms of patients with PD were evaluated, and a resting-state functional magnetic resonance imaging (RS-fMRI) study was conducted based on propensity score matching. Alterations in brain function were analyzed using regional homogeneity (ReHo) and functional connectivity (FC). Compared with patients without constipation (PD-NC group), patients with constipation (PD-C group) had more serious motor and non-motor symptoms (including cognitive and emotional disorders along with visual hallucinations). Further, emotional and cognitive disorders were correlated with the occurrence of constipation in patients with PD. Compared with the PD-NC group, the PD-C group showed a reduced ReHo of the right insula and bilateral orbitofrontal cortex (OFC), increased ReHo of the left postcentral gyrus, and enhanced FC between the right OFC and the left middle temporal gyrus (MTG) and middle occipital gyrus (MOG). Additionally, the activity of the OFC and insula was significantly correlated with the constipation, mood, and cognitive levels of patients with PD. Constipation in patients with PD is closely related to emotional and cognitive impairments, abnormal activity and FC of brain regions such as the right insula and bilateral OFC may play an important role in this.

Introduction: Diabetic retinopathy (DR), a microvascular complication of type 2 diabetes mellitus (T2DM), is a leading cause of blindness and has detrimental effects on patients' quality of life. We compared the risk of DR diagnosis with sodium-glucose cotransporter-2 inhibitors (SGLT2i) versus dipeptidyl peptidase-4 inhibitors (DPP-4i) in patients with T2DM in Japan. Methods: This Japanese retrospective cohort study used the JMDC Claims Database (data collected from January 2015 to September 2022). Patients with T2DM and no record of microvascular or macrovascular diseases who were newly treated with an SGLT2i (23,061 patients) or a DPP-4i (53,986 patients) were matched 1:1 using propensity score (10,166 per matched group). Incidence rates (IRs) and cumulative IRs of DR diagnosis were calculated for each treatment group; hazard ratio (HR) and its 95% confidence interval (CI) were calculated using Cox proportional hazard models to compare the risk between the groups. Results: The IR of DR diagnosis was 46.23 and 57.12 per 1000 person-years in the SGLT2i and DPP-4i groups, respectively, with a significantly lower risk in the SGLT2i group than in the DPP-4i group (HR 0.83, 95% CI 0.75–0.92, P = 0.0003). Conclusions: In this study, the risk of DR diagnosis was lower with SGLT2i compared with DPP-4i in patients with T2DM without microvascular and macrovascular diseases in Japan. Findings suggest that early SGLT2i treatment may be beneficial in preventing DR development in early-stage T2DM. Graphical abstract available for this article. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to investigate the prognostic value of systematic inflammatory response in patients with lymph node-negative colorectal cancer. Methods: We retrospectively investigated 245 patients with lymph node-negative colorectal cancer who underwent curative resection and evaluated the prognostic impact of systematic inflammatory response, which was represented by neutrophil-to-lymphocyte ratio (NLR), prognostic nutritional index (PNI), and C-reactive protein-to-albumin ratio (CAR). Then, the prognostic significance of the systematic inflammatory response on survival was analyzed using the Kaplan-Meier method in patients selected by propensity score matching (PSM) analysis. Results: In the multivariate analysis, CAR ≥ .081 (P = .004) was independent predictors of disease-free survival, while American Society of Anesthesiologists physical status ≥3 (P = .049) and CAR ≥ .081 (P < .001) were independent predictors of overall survival. By PSM analysis, PSM-high-CAR was significantly associated with worse disease-free survival (P = .043) and overall survival (P = .041) in patients with lymph node-negative colorectal cancer. Conclusions: C-reactive protein-to-albumin ratio may be a significant indicator of poor long-term outcomes in patients with lymph node-negative colorectal cancer. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to investigate the characteristics of patients with colorectal mucinous adenocarcinoma (MAC) who benefit from postoperative chemotherapy (POCT) and to develop effective postoperative survival nomograms for predicting overall survival (OS) in colorectal MAC patients. Methods: Data of colorectal MAC patients who underwent surgery from the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2020 were collected. Patients were grouped based on POCT, and intergroup analysis was performed using 1:1 propensity score matching (PSM). Kaplan-Meier (K-M) curves were used to compare the prognosis between the 2 groups. Cox analysis was employed to identify factors associated with OS in patients with colorectal MAC who underwent POCT. The variance inflation factor (VIF) and bilateral stepwise regression were used to determine factors included in the model. Additionally, a nomogram was constructed to predict postoperative survival outcomes for patients. The discriminative ability of the nomograms was evaluated using the C-index and calibration curve analysis, the decision curve analysis (DCA) assessed the clinical utility of the nomogram, and the receiver operating characteristic (ROC) curve evaluated the nomograms' performance. Results: This study encompassed 6829 patients with colorectal MAC, among whom 2258 received POCT, and 4571 did not. Whether pre or post PSM, patients in the POCT group consistently exhibited a superior median OS compared to those in the postoperative non-chemotherapy group (P < .0001). For colorectal MAC patients undergoing POCT, OS was correlated with factors such as patient age, carcinoembryonic antigen levels, tumor deposits, perineural invasion (PNI), lymph node examination count, T staging, and Grade staging. Notably, a significant chemotherapy advantage was observed in patients without perineural invasion, those with lymph node examination counts exceeding 12, and patients with moderately differentiated tumors. The overall colorectal MAC patient postoperative OS predictive nomogram demonstrated a C-index of .74, with a calibration curve near the diagonal and a DCA curve indicating positive net benefits. In comparison to TNM staging, the ROC curves of the nomogram at 1 year, 3 years, and 5 years demonstrated superior predictive capabilities (AUC: .80 vs .71, .78 vs .71, .77 vs .70). Conclusion: This study revealed the characteristics of colorectal MAC patients who benefit from POCT and established effective prognostic nomograms, which can aid clinicians in designing personalized treatment plans for individual patients and promote precision medicine.

Background: The association between surgical approach and post-hepatectomy liver failure (PHLF) in cirrhotic patients is poorly understood. We hypothesize that patients will have similar rates of liver failure regardless of whether they undergo minimally invasive liver resection (MILR) or open liver resection (OLR) in major liver resections. In contrast, there will be lower rates of PHLF in patients undergoing minor hepatectomy via the MILR approach.Methods: Propensity score matching was used to analyze regression by matching the MILR to the OLR cohort. Patient demographics from the American College of Surgeons National Surgical Quality Improvement Program, including race, age, gender, and ethnicity, were matched. Chronic obstructive pulmonary disease, congestive heart failure, smoking, hypertension, diabetes, renal failure, dyspnea, dialysis dependence, body mass index, and American Society of Anesthesiologists (ASA) classification (>ASA III) were among the preoperative patient characteristics subject to matching. PHLF (Grade A vs B. vs C) was our primary outcome measure.Results: A total of 2129 cirrhotic patients were included in the study. In the minor hepatectomy group, patients undergoing an OLR were more likely to get discharged to a facility (7.0% vs 4.4%; P = .03), had greater hospital length of stay (5 vs 3 days; P = .02), and had a greater need for invasive postoperative interventions (10.7% vs 4.6%; P < .01). They were also noted to have higher rates of organ space superficial surgical infections (SSIs) (7.3% vs 3.7%; P = .003), Clostridium difficile infection (.9% vs .1%; P = .05), renal insufficiency (2.1% vs .1%; P < .01), unplanned intubations (3.1% vs 1.4%; P = .03), and Grade C liver failure (2.3% vs .9%; P = .03).Conclusion: A higher incidence of PHLF grade C was found in patients undergoing OLR in the minor hepatectomy group. Therefore, in cirrhotic patients who can tolerate minimally invasive approaches, MILR should be offered to prevent postoperative complications as part of their optimization plan.

Background: Proximal gastrectomy (PG) is one of function-preserving gastrectomy (FPG). In this study, we compared the long-term results of proximal gastric cancer (PGC) patients undergoing proximal gastrectomy and total gastrectomy (TG). Method: Patients diagnosed with PGC and receiving PG or TG between 2004 and 2020 were selected from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was applied to minimize confounding factors. Kaplan-Meier analysis and log-rank test were used to compare overall survival (OS) and cancer-specific survival (CSS) between the PG and TG groups. Univariate and multivariate Cox regression analyses were performed to identify independent risk factors affecting OS. Result: A total of 3916 patients were recruited according to the inclusion and exclusion criteria, with 2614 undergoing PG and 1302 undergoing TG. After 1:1 PSM matching, 912 pairs of data were included for analysis. Before PSM matching, PG group tended to have better OS and CSS outcomes. However, after PSM matching, both surgical approaches showed similar long-term results. Conclusion: PG for PGC yields comparable long-term outcomes to TG and demonstrates safety in terms of oncologic outcomes. [ABSTRACT FROM AUTHOR]

Background: Congenital heart disease (CHD) is one the most common congenital anomalies, with a prevalence of 8-10 cases per 1000 live births in the United States. Congenital heart disease has been recognized as a risk factor for poor perioperative and postoperative outcomes in non-cardiac surgery. We aimed to determine if documentation of CHD-related diagnosis codes was associated with similar risks for trauma surgery. Methods: Data were acquired from the 2010-2019 American College of Surgeons' Trauma Quality Programs Participant Use Files. This study included trauma patients of all ages with one or more surgical procedures and at least one documented non-trauma (comorbidity) International Classification of Diseases code. Patients were stratified based on presence of CHD-related comorbidity codes vs any other comorbidity. Outcomes included mortality, hospital length of stay (LOS), discharge disposition, and in-hospital complications. Results: Using 1:1 propensity score matching, we matched 215 cases with CHD-related comorbid diagnoses to non-CHD controls. Compared to patients with other comorbidities, patients with CHD-related comorbidites were less likely to be discharged home to self-care (odds ratio: 0.44, 95% confidence interval [CI]: 0.25, 078 P = .005) and tended to have prolonged hospital LOS (incidence rate ratio [IRR]: 1.06, 95% CI: 1.001, 1.13, P = .046). Conclusions: We present the first quantitative multicenter analysis correlating documentation of comorbid CHD-related diagnoses with higher risk of adverse outcomes after trauma surgery. These results support the need to routinely acknowledge and document CHD as comorbidity in trauma admissions that could lead to surgical intervention and for trauma centers to prepare for patients with a possible CHD comorbidity.

Due to the rarity of lung cancer with cystic imaging manifestations, we explore the clinical features and survival prognosis of such tumors. Imaging characteristics were used to categorize 3,556 patients who underwent surgery for isolated primary lung cancer into one of three groups: those with cystic lung cancer (149), solid lung cancer (1,399), and ground-glass lung cancer (1,160). Propensity score matching by sex and age was performed to analyze the differences in clinical characteristics of lung cancer among the three groups and the correlation between clinical characteristics of cystic lesions and progression-free survival (PFS). The three groups of patients differed in various aspects, including pathological type, smoking history, tumor stage, type of surgery, histological grading, and PFS (P < 0.05). The results of the multifactorial analysis indicated that lung cancer type, pathological type, lymph node metastasis, tumor stage, and histologic grading were independent prognostic factors for lung cancer (P < 0.05). After comparison, there was a difference in prognosis between cystic lung cancer and ground-glass lung cancer (P < 0.05). The clinical features of cystic lung cancer are significantly different from those of ground-glass lung cancer and solid lung cancer. Cystic lesions are independent influencing factors affecting lung cancer, and the prognosis of cystic lung cancer is worse than that of ground-glass lung cancer. • LCCAs have different clinical features from other types of lung cancer. • Prognosis of LCCAs is statistically different from ground-glass lung cancer. • Cystic lesions are an independent influence on non-small cell lung cancer.

Background: Seasonal variations in systemic immunity have been reported. This study aimed to evaluate whether seasonality affects the efficacy of anticancer immunotherapy. Methods: A total of 604 patients with lung cancer receiving single anti–programmed cell death (ligand) 1 (anti–PD‐[L]1) inhibitors from two prospective observational cohorts were screened. Primary outcomes were progression‐free survival (PFS) and overall survival (OS). Patients were classified into two groups according to the season when the treatment started: winter (November–February) and other seasons (March–October). Kaplan–Meier analysis and Cox proportional hazards models were fitted to evaluate the impact of seasonality on survival. For validation, propensity score matching was performed. Results: A total of 484 patients with advanced non–small cell lung cancer were included. In an unmatched population, multivariable analysis demonstrated that the winter group (n = 173) had a significantly lower risk of progression or death from immunotherapy than the other group (n = 311) (PFS: hazard ratio [HR], 0.77 [95% confidence interval (CI), 0.62–0.96]; p =.018; OS: HR, 0.77 [95% CI, 0.1–0.98]; p =.032). In a propensity score–matched population, the winter group (n = 162) showed significantly longer median PFS (2.8 months [95% CI, 1.9–4.1 months] vs. 2.0 months [95% CI, 1.4–2.7 months]; p =.009) than the other group (n = 162). The winter group's median OS was also significantly longer than that of the other group (13.4 months [95% CI, 10.2–18.0 months] vs. 8.0 months [95% CI, 3.6–8.7 months]; p =.012). The trend toward longer survival in the winter group continued in subgroup analyses. Conclusions: Starting an anti–PD‐(L)1 inhibitor in winter was associated with better treatment outcomes in patients with lung cancer compared to other seasons. Patients with lung cancer who started anti–programmed cell death (ligand) 1 inhibitor treatment in the winter season from November to February showed significantly better survival outcomes than those who started treatment in the other seasons. This observation was validated in further analysis via propensity score matching. [ABSTRACT FROM AUTHOR]

Background: Limited evidence exists to support any specific medication over others to prevent dementia in older patients with type 2 diabetes (T2D). We investigated whether treatment with sodium‐glucose cotransporter 2 (SGLT‐2) inhibitors is associated with a lower risk of incident dementia and all‐cause mortality, relative to dipeptidyl peptidase‐4 (DPP‐4) inhibitors and glucagon‐like peptide‐1 receptor agonists (GLP‐1 RA). Methods: In this retrospective, active‐comparator cohort study, we used data from the TriNetX electronic health records network. Our primary cohort comprised patients with T2D aged ≥50 years, registered between January 2012 and December 2022. Patients with a history of dementia were excluded. We used Kaplan–Meier survival analysis to estimate the incidence of dementia and all‐cause mortality in our cohort after they had used glucose‐lowering drugs for at least 12 months. Propensity score matching was performed to balance the SGLT‐2 inhibitor, DPP‐4 inhibitor and GLP‐1 RA cohorts. Subgroup analyses for sex and age were also conducted. Results: Our first cohort comprised 193 948 patients treated with metformin and SGLT‐2 inhibitors and an equal number of patients treated with metformin and DPP‐4 inhibitors. In this cohort, the risk of dementia and all‐cause mortality was lower in patients treated with SGLT‐2 inhibitors than in those treated with DPP‐4 inhibitors (hazard ratio [HR]: 0.62, 95% confidence interval [CI]: 0.59–0.65, for dementia; HR: 0.54, 95% CI: 0.52–0.56, for all‐cause mortality). Our second cohort comprised 165 566 patients treated with metformin and SGLT‐2 inhibitors and an equal number of patients treated with metformin and GLP‐1 RAs. In this cohort, the risk of dementia and all‐cause mortality was lower in those treated with SGLT‐2 inhibitors than in those treated with GLP‐1 RAs (HR: 0.92, 95% CI: 0.87–0.98, for dementia; HR: 0.88, 95% CI: 0.85–0.91, for all‐cause mortality). Conclusions: The use of SGLT‐2 inhibitor was associated with a lower risk of incident dementia and all‐cause mortality in older adults with T2D compared to DPP‐4 inhibitor and GLP‐1 RA.

Aim: To investigate whether the physician‐encounter interval for patients with type 2 diabetes (T2D) can be optimized from 2–3 to 4–6 months among those with a calculated 10‐year cardiovascular disease (CVD) risk score of less than 20% without compromising their long‐term outcomes. Materials and Methods: Using territory‐wide public electronic medical records in Hong Kong, we emulated a target trial to compare the effectiveness of the physician‐encounter intervals of 4‐6 versus 2‐3 months for T2D patients without prior CVDs and with a predicted risk for CVDs of less than 20% (i.e. those patients not in the high‐risk category). Propensity score matching was used to emulate the randomization of participants at baseline, where 42 154 matched individuals were included for analysis. The marginal structural model was applied to estimate the hazard ratio (HR) for CVD incidence and all‐cause mortality, the incidence rate ratio of secondary and tertiary care utilization, as well as the between‐group differences in HbA1c, blood pressure and cholesterol levels. Results: During a follow‐up period of up to 12 (average: 5.1) years, there was no significantly increased risk of CVD in patients with physician‐encounter intervals of 4‐6 months compared with those patients with physician‐encounter intervals of 2‐3 months (HR [95% confidence interval {CI}]: 1.01 [0.90, 1.14]; standardized 10‐year risk difference [95% CI]: −0.1% [−0.7%, 0.6%]), nor for all‐cause mortality (HR: 1.00 [0.84, 1.20]; standardized 10‐year risk difference: −0.1% [−0.5%, 0.3%]). Additionally, there was no observable difference in the utilization of secondary and tertiary care or key clinical parameters between these two follow‐up frequencies. Conclusions: For T2D patients with a calculated 10‐year CVD risk of less than 20%, the interval of regular physician encounters can be optimized from 2–3 to 4–6 months without compromising patients' long‐term outcomes and saving substantial service resources in primary care.

Aim: We aimed to investigate the long‐term impact of glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) on thyroid function, cardiovascular health, renal outcomes and adverse events in individuals with obesity and without type 2 diabetes (T2D). Materials and Methods: In this observational cohort study, we used propensity score matching to construct comparable cohorts of individuals with obesity and without T2D who were new to GLP‐1 RA treatment and those who did not receive glucose‐lowering medications. In total, 3,729,925 individuals with obesity were selected from the TriNetX Global Network, with an index event between 1 January 2016 and 31 March 2024. The primary outcomes were safety, cardiovascular, thyroid and clinical biochemical profile outcomes occurring within 5 years following the index event. Results: After propensity score matching, the study included 12,123 individuals in each group. GLP‐1 RA treatment was associated with a significantly lower risk of all‐cause mortality (hazard ratio 0.23; 95% confidence interval 0.15–0.34) and several cardiovascular complications, including ischaemic heart disease, heart failure, arrhythmias, hypertension, stroke and atrial fibrillation (all p < 0.05). GLP‐1 RAs were also associated with a lower risk of acute kidney injury and allergic reactions. These protective effects were consistent across various subgroups and regions. Conclusions: In this large observational study, GLP‐1 RAs showed long‐term protective effects on cardiovascular health, renal outcomes and adverse events in individuals with obesity and without T2D. Our findings suggest that GLP‐1 RAs may offer a comprehensive approach to managing obesity and its related comorbidities, potentially improving overall health and survival in this population.

The current evidence for the use of nanoparticle albumin-bound paclitaxel (nab-PTX) for adjuvant breast cancer chemotherapy is insufficient. The present study aimed to assess the efficacy and toxicity of nab-PTX in comparison with solvent-based paclitaxel (sb-PTX) in postoperative adjuvant breast cancer treatment. A total of 345 patients were included in the study and separated into nab-PTX (n=289) and sb-PTX (n=56) groups based on the type of taxane used in the adjuvant chemotherapy regimen. The study evaluated the baseline characteristics in both groups and the risk factors for postoperative recurrence of mammary cancer. Furthermore, data concerning disease-free survival (DFS) and adverse effects were obtained and analyzed, and group confounding variables were addressed using 1:2 propensity score matching (PSM). Comparisons before PSM revealed significant differences in baseline characteristics including age, underlying disease, lymph node involvement, vascular invasion, human epidermal growth factor receptor 2 and axillary surgery (P<0.05). Following PSM, there were 90 patients in the nab-PTX group and 56 in the sb-PTX group, with no significant differences in the baseline differences (P>0.05). Before PSM, the 73-month DFS rate was 97.9% in the nab-PTX group compared with 91.1% in the sb-PTX group. However, there were no significant differences between the groups before or after PSM (P=0.15 and P=0.49, respectively). Additionally, Cox regression analysis demonstrated a significantly lower chance of recurrence in patients aged >45 years [hazard ratio (HR), 0.197; 95% confidence interval (CI), 0.052-0.753; P=0.018], whereas underlying disease (HR, 5.352; 95% CI, 1.310-21.854; P=0.019) and lymph node infiltration (HR, 8.930; 95% CI, 1.121-71.161; P=0.039) significantly increased the risk of recurrence. Regarding safety, the sb-PTX group had a significantly greater incidence of anaphylaxis, whereas the nab-PTX group had significantly increased rates of anemia and peripheral neuropathy (P<0.05). In summary, the 73-month DFS rate of the nab-PTX cohort exceeded that of the sb-PTX cohort, but no significant difference was detected between them. Underlying disease, lymph node metastasis and an age of ≤45 years are significant predictors of postoperative recurrence of breast cancer. [ABSTRACT FROM AUTHOR]

Introduction: Psychiatric disorders are common during pregnancy, affecting up to 16% of pregnant women. Severe depression and anxiety have significant negative effects on the health of both the mother and the developing fetus. Electroconvulsive therapy (ECT) is considered a treatment option for pregnant women with severe psychiatric disorders when other treatments have been ineffective or pose risks to the fetus. Knowledge of the safety and efficacy of ECT during pregnancy, however, remains limited. Methods: Data were obtained from nationwide registries of pregnant women in Sweden who received ECT for a severe psychiatric disorder from January 2008 to December 2021. ECT‐related outcomes in pregnant women were compared by propensity score matching with a group of non‐pregnant women who also received ECT. Pregnancy‐related outcomes were compared with two additional control groups: one consisting of the same group of women who did not receive ECT during another pregnancy and the other composed of pregnant women admitted to inpatient psychiatric care but who did not receive ECT, matched based on propensity score. Results: Ninety‐five pregnant women received ECT during the study period, accounting for 97 pregnancies. The response rate to ECT in pregnant women (n = 54) was similar to the matched control group of non‐pregnant women (74% vs. 65%; OR 1.61; 95% CI 0.79–3.27). Rates of adverse events related to ECT were similar to those in the control group. There were no pre‐term births or severe adverse outcomes related to the pregnancy, that were close in time to ECT. Therefore, no adverse outcomes related to pregnancy and childbirth could be directly attributed to ECT. The likelihood of premature birth and a 5‐min Apgar score <7 in the newborn were both significantly higher in the ECT group, compared with the matched non‐ECT group (OR 2.33, 95% CI 1.15–4.73, p = 0.008, and OR 3.68, 95% CI 1.58–8.55, p < 0.001, respectively). By contrast, no significant differences were observed when women in the pregnant ECT group were compared with the same group lacking ECT during another pregnancy. Conclusions: ECT was associated with a positive treatment response in pregnant women with severe psychiatric disorders. The response rate to ECT was similar in pregnant and non‐pregnant women. Nevertheless, the risks of premature birth and of a slightly poorer condition in newborns were higher in women who did than did not receive ECT, emphasizing the need for increased attention to severe psychiatric disorders during pregnancy.

Several data sets have demonstrated a correlation between lymphovascular invasion (LVI) and locoregional recurrence (LRR). Whether the observation of "extensive LVI" is a further and incremental determinant of LRR risk is unknown. We describe clinical outcomes in women with invasive breast cancer stratified by (1) absence of LVI (neg), (2) LVI focal or suspicious (FS-LVI), (3) usual (nonextensive) LVI (LVI), and (4) extensive LVI (E-LVI). Between December 2009 and August 2021, 8837 patients with early-stage breast cancer were treated with curative intent and were evaluable. Clinical-pathologic details were abstracted by retrospective review. The description of LVI was abstracted from pathology reports. Recurrence and survival outcomes were compared based on the extent of LVI. A matched propensity score analysis compared outcomes between patients with LVI versus E-LVI. Of the 8837 patients studied, 5584 were negative, 461 had FS-LVI, 2315 had LVI, and 477 had E-LVI. Patients with E-LVI had an adverse risk profile compared with the other groups. The 5- and 10-year LRR cumulative incidence estimates in patients with E-LVI were 9.6% (95% CI, 7.1-13) and 13% (95% CI, 10-17), respectively, which were significantly higher than those observed in the usual LVI group (6.8% [5.7-7.9] and 10% [8.8-12], respectively). A statistically significant difference in LRR was demonstrated in univariable (HR, 1.4; 95% CI, 1.03-1.89; P =.029) and multivariable regression analysis (HR, 1.62; 95% CI, 1.15-2.27; P =.005) compared with nonextensive LVI. In an alternative approach, we performed a 2:1 propensity score matching analysis comparing patients with LVI to those with E-LVI. The hazard ratio for LRR (HR, 1.47; CI 1.02-2.14; P =.041) was suggestive of a higher risk associated with E-LVI. Our work suggests that patients with E-LVI are at a higher risk for LRR than those with usual LVI. For patients who are borderline candidates for regional nodal irradiation or post-mastectomy radiation therapy, the finding of E-LVI might be decisive in favor of intensified treatment.

Since the appropriate antibiotic duration for uncomplicated Staphylococcus aureus (S. aureus) bacteremia (u-SAB) in an immunocompromised state is still unclear, physicians are likely to extend antibiotic therapy from 2 weeks to 4–6 weeks. To examine the appropriate duration of antibiotic therapy for u-SAB, we performed this study. We reviewed all patients with u-SAB at our institute seen between January 2020 and August 2023. A total of 51 patients were enrolled, and they were divided into the following two groups by antibiotic duration: longer duration group ≥28 days after blood culture negativity, and shorter duration group. Then, the patients were matched by a propensity score using the covariates of age, sex, qSOFA, and CCI. The primary outcome was to identify the prognosis by duration of antibiotic treatment. After propensity score matching, all-cause 30-day mortality was 0 % in both groups. Hence, there was no significant difference in all-cause 90 days mortality (19.0% vs 9.5%, p = 0.33) or recurrence (9.5%% vs 0%, p = 0.22). Before propensity-score matching, we found that a serum level of CRP 2.0 mg/dL and greater after intravenous antibiotic treatment was one of the poor prognostic factors. The cut-off value of serum CRP level was 2.0 mg/dL with a sensitivity of 82.1% and a specificity of 75.0%. We suggested that 4–6 weeks of antibiotic treatment for immunodeficient u-SAB patients was unnecessary. Moreover, the serum level of CRP after completion of IV antibiotic treatment could be a prognostic marker for u-SAB. [ABSTRACT FROM AUTHOR]

The global energy era is accelerating ahead of schedule. At the urban level, can large-scale utilization of renewable energy in cities promote energy consumption reduction and economic cost saving, improving energy economic efficiency (EEE)? Based on balanced panel data for 260 prefecture-level cities in China from 2010 to 2020, we used data envelope analysis (DEA) window analysis and difference-in-differences and propensity score matching to evaluate the effect of the New Energy Demonstration City Program on urban EEE. We found that the policy promoted the improvement of urban EEE. However, there is specific regional heterogeneity in the policy effects, with this policy having a more significant effect on EEE improvements in the Northeast, cities with high pollution levels, and cities with high-tech innovation levels. These findings have significant policy implications for supporting the country in promoting the development and utilization of new energy sources to improve EEE. [ABSTRACT FROM AUTHOR]

Postpartum depression is a major psychiatric disorder associated with maternal suicide and child developmental disturbances. In this study, we aimed to investigate whether general anesthesia for cesarean delivery is associated with a higher rate of new-onset depression after delivery than neuraxial anesthesia. This is a nationwide retrospective cohort study using data retrieved from the National Health Insurance Research Database between 2014 and 2018. Women who had cesarean delivery under general or neuraxial anesthesia were enrolled. After 1:4 propensity score matching, there were 4544 and 18,176 women under the general and neuraxial anesthesia groups, respectively. The primary outcome was new-onset depression diagnosed after delivery in a time-to-event analysis setting. After propensity-score matching, the rate of new-onset depression diagnosed within 1 year was 1.10 % (50/4488) and 0.86 % (157/18176) after cesarean delivery under general and neuraxial anesthesia, respectively. For depression diagnosed within 90 days of delivery, significant difference between the two groups was noted (0.51 % vs. 0.30 %, P = 0.031). In the time-to-event analysis with Cox regression model, women who delivered under general anesthesia were associated with significantly higher risk of postpartum depression within 90 days (Hazard ratio [HR], 1.71; 95 % CI, 1.05–2.79) compared with those under neuraxial anesthesia. The observational design only allows asserting association, rather than establishing causality between exposure and outcomes. Women who underwent cesarean delivery under general anesthesia had a higher risk of subsequent depression within 90 days than those under neuraxial anesthesia. Early screening for depressive disorders might facilitate timely management. [Display omitted] • Postpartum depression may lead to serious consequences, including maternal suicide. • Effect of neuraxial and general anesthesia on subsequent depression was compared. • C-section under general anesthesia may be associated with subsequent depression.

Limited evidence exists on the association between malnutrition diagnosis using the Global Leadership Initiative on Malnutrition (GLIM) criteria in hospitalized acute care patients and their outcomes; several aspects still require clarification. This study aimed to evaluate the relationship between malnutrition, as defined by the GLIM criteria, at the time of acute hospital admission and discharge to home. This retrospective observational study was conducted at a hospital that provides acute care in Japan. Adult patients admitted between July 2023 and April 2024 were included in this study. The primary outcome was the number of patients discharged to home, with in-hospital mortality as the secondary outcome. To ensure the reliability of the cohort-wide results, background factors were adjusted using propensity score matching. The two groups were compared based on the presence or absence of malnutrition, as defined by the GLIM criteria at admission. Furthermore, multiple logistic regression analysis was conducted, with the outcome as the dependent variable and malnutrition, diagnosed using the GLIM criteria, as the explanatory variable, adjusting for covariates. A total of 1007 patients were included in the final analysis, of whom 492 (49 %) were diagnosed without malnutrition, while 515 (51 %) were diagnosed with malnutrition according to the GLIM criteria. In the multivariate logistic regression analysis after matching, malnutrition defined by the GLIM criteria emerged as an independent factor associated with discharge to home (odds ratio [OR] = 0.37, 95 % confidence interval = 0.25–0.56, P < 0.001) when adjusting for age, sex, and various comorbidities. Among the GLIM sub-criteria, reduced muscle mass, reduced food intake or assimilation, and disease burden or inflammation were independently associated with discharge to home. Notably, disease burden/inflammation exhibited the lowest OR among the GLIM sub-criteria for discharge. Malnutrition diagnosed using the GLIM criteria upon admission in patients admitted to a regional hospital providing acute care was associated with decreased rates of discharge to home and increased in-hospital mortality. Specifically, attention should be paid to the criteria for reduced muscle mass and disease burden or inflammation within the GLIM framework. [ABSTRACT FROM AUTHOR]

Objective: This study aims to investigate how arthritis, including osteoarthritis and rheumatoid arthritis, affects the incidence of nocturia in adults aged 20–59. Methods: This study utilized data from the National Health and Nutrition Examination Survey from 2005 to 2020, involving 18 745 adults aged 20–59. Arthritis, including osteoarthritis and rheumatoid arthritis, was considered as the exposure factor, with nocturia as the outcome variable. We first compared the baseline characteristics of individuals with and without nocturia. The impact of arthritis on nocturia was assessed using weighted multivariate logistic regression models. To ensure the stability of the results, propensity score matching analysis and subgroup analyses were conducted. Results: The incidence of nocturia was approximately 22.31%, and the incidence of arthritis was about 15.32% (2871/18 745), with osteoarthritis accounting for 35.49% (1019/2871) and rheumatoid arthritis accounting for 20.20% (580/2871). Adjusted multivariate logistic regression analysis revealed that the risk of nocturia was increased by arthritis (odds ratio [OR] = 1.45, 95% confidence interval [CI]: 1.28–1.65, p < 0.0001), including osteoarthritis (OR = 1.45, 95% CI: 1.18–1.78, p < 0.001) and rheumatoid arthritis (OR = 1.51, 95% CI: 1.14–2.00, p = 0.004). After propensity score matching using nearest neighbor methods at a 1:1 ratio, this relationship still exists. Subgroup analyses showed no significant differences in the interactions between arthritis and the risk of nocturia across various factors, such as age, family income to poverty ratio, education level, body mass index, smoking status, hypertension, and diabetes. However, significant differences were observed across different sex groups and sleep trouble groups. Conclusions: This study revealed that arthritis, including osteoarthritis and rheumatoid arthritis, increased the risk of nocturia in adults under the age of 60. [ABSTRACT FROM AUTHOR]

Purpose: Historically, most CEOs were promoted from within the organization. The internal candidates offer continuity, are well known to the Board, and have deep institutional knowledge. However, if the Board is seeking changes to the firm's strategy, operations, or culture, they turn to outside candidates with proven track records. Shareholders react positively to the announcement of an external successor but the longer-term evidence on the performance front is mixed. Most empirical studies have tended to focus on a narrow aspect of the hiring choice, whereas we undertake a more holistic examination involving various elements. Design/methodology/approach: We consider the salience of the CEO hiring choice from several perspectives: educational background, gender, compensation, and firm performance. We use a propensity score matching approach to ensure comparability between internally promoted and externally hired CEOs. The observed covariates for the matching algorithm include firm size, CEO tenure, and industry sector. Findings: We find that external CEOs are significantly more likely to have received their undergraduate degree from an elite institution, majored in a STEM discipline, and earned an MBA credential. They earn higher total compensation (with a higher proportion of equity-linked performance pay) but do not outperform in terms of the ROA or Tobin's Q metrics. Gender does not appear to play a distinguishing role in the internal versus external hiring choice. We also do not detect significant differences in firm performance outcomes associated with educational pedigree, a STEM education, or an MBA credential, whether the CEO is internally promoted or hired externally. Originality/value: Our paper contributes by providing novel evidence on the impact of educational background on external CEO hiring decisions. Our findings carry implications for testing hypotheses stemming from signaling theory and exploring the significant role of social networks associated with elite educational institutions. Also, the finding that externally appointed CEOs do not outperform their internally promoted counterparts may be noteworthy for corporate boards' hiring committees, especially when reviewing candidates who are edge cases.

This study examines how natural catastrophes affect corporate philanthropic activities in China. Firms located in areas experiencing severe seismic losses increase charitable donations. The effect is stronger when firms demonstrate stronger social responsibility, operate in higher-mortality regions, and are led by female or elder CEOs, supporting the mortality salience hypothesis. We address endogeneity issues with an instrumental variable and a propensity score matching approaches. Furthermore, firms with higher charitable donations experience a more positive stock market reaction around the 2008 Wenchuan Earthquake. Overall, our findings suggest that natural catastrophes amplify financial market participants' mortality salience and affect their economic decisions. [ABSTRACT FROM AUTHOR]

Objectives: To estimate how many offenses are averted through the incapacitation of first-time incarcerated offenders with sentences of two years or less. Methods: The counterfactual challenge of estimating criminal acts that would have been committed had the offender not been incarcerated is approached utilizing a matching design. Data comprise all offenders convicted in Sweden in 2018, matched on a vector of time-stable and time-varying covariates drawn from an extensive set of Swedish registers. Each incarcerated offender is matched to a nonincarcerated offender whose offending frequency is used to infer the incapacitation effect. Full sample estimates are provided as well as subgroup estimates for males, females, and various risk groups. Results: The annual incapacitation effect for first-time incarcerated offenders is estimated to be 0.53 when measured as the number of averted convictions and 1.14 when measured as the number of averted offenses that would have resulted in a conviction. For males, the annual number of convictions averted through incapacitation is 0.51, and for females 0.37. For the highest risk group, the annual number of averted convictions is 1.22, and the number of averted offenses resulting in conviction is 2.55. For offenders in the low-to-medium risk groups, the corresponding figures are approximately 0.31 averted convictions and approximately 0.68 averted offenses. Conclusion: For first-time incarcerated offenders, the incapacitation effect is modest and the heterogeneous effects found across different risk groups warrant considering whether the crime-preventive effect is sufficiently large for low-risk inmates and whether noncustodial sanctions might constitute an alternative that would ease overcrowding without producing any considerable risk for costs in terms of recidivism.

Background: The risk of cardiac disease mortality has recently become a focal point of concern within the medical community for patients with prostate cancer (PCa). Given that radical prostatectomy (RP) and external beam radiation therapy (EBRT) are the main treatment modalities for localized PCa, their specific impact on cardiovascular-specific mortality (CSM) remains unclear. This study explored the specific effects of RP and EBRT on CSM risk to guide clinical treatment decisions. Methods: Data from patients aged 45–74 years, who were diagnosed with T1-2N0M0 stage PCa from the SEER database (2010–2015), were used. Multivariate statistical methods, including propensity score matching (PSM), competing risk regression, COX regression analysis, and Fine-Gray testing, were applied to assess the impact of RP and EBRT on CSM risk. Results: Among 146,082 T1-2 stage PCa patients, cardiac disease emerged as the primary cause of death, surpassing PCa itself. Multifactorial COX regression and competing risk regression analyses indicated that local treatments do not increase CSM risk. Further analysis revealed a significant increase in CSM risk for patients undergoing only EBRT compared with those undergoing only RP (hazard ratio [HR] = 2.71, 95% confidence interval [CI] 1.96–3.74, P < 0.001), with subsequent PSM adjustment, further confirming a significantly reduced risk in the RP treatment group (HR 0.23, 95% CI 0.13–0.40, P < 0.001). Conclusions: T1-2 stage PCa patients face a significant risk of CSM, with RP offering a potential advantage over EBRT in reducing this risk. These findings encourage clinicians to comprehensively consider the potential impact on cardiac health when formulating treatment plans, providing crucial guidance for optimizing treatment strategies.

This article presents the one‐sided intellectual influence of Economics on Urban Studies & Planning, the case of two social science disciplines with different epistemologies and approaches to policy advice. Subsequently, it presents the emergence of the so‐called evidence based policy (EBP) approach in Economics, comprising experimental (randomized control trial) and quasi‐experimental (difference‐in‐differences and propensity score matching) methods. The article shows that even though EBP claims to be exempt from normative/political, and even theoretical, considerations, it builds upon two features of neoclassical economics: sufficiency and separability. These conditions comprise its normative neoclassical theory background. We discuss the neoliberal turn in development narratives and their influence on urban planning, which coincides with the emergence of EBP. We analyze some EBP examples in the urban planning scholarship. [ABSTRACT FROM AUTHOR]

Based on the Shanghai-Hong Kong stock connect and the Shenzhen-Hong Kong stock connect (China Connect), we use the difference-in-differences combined with propensity score matching method to investigate firm's response in innovation activity to stock market openness. Our findings reveal that the stock market openness has a positive impact on innovation quality. Moreover, the China Connect improves the innovation quality through relaxing financial constraint and improving stock liquidity. Our research shows that the stock market openness plays an important role in shaping the innovation ability of real economy. [ABSTRACT FROM AUTHOR]

This article empirically analyzes the impact of hedge fund activism on audit quality in emerging markets represented by China. It is found that hedge fund holding can significantly improve the audit quality of listed companies, but the above-mentioned effect is limited to private enterprises and companies with dispersed equity, yet not significant in state-owned enterprises (SOEs) and companies with concentrated equity. In addition, hedge fund activism becomes more prominent when auditors and analysts fail to play a governance role. Further tests show hedge funds influence audit quality through certain activism campaigns. We also use instrumental variable (IV) and propensity score matching method (PSM) to alleviate the endogeneity problem. The conclusion of this article contributes empirical evidence from emerging markets to the controversial topic of hedge fund activism. [ABSTRACT FROM AUTHOR]

Objective Methods Results Conclusions Surgical treatment for renal cell carcinoma (RCC) has drastically evolved for the past 30 years. However, survival outcomes of RCC according to times have not been fully elucidated, especially in the real‐world setting. This study aimed to assess the survival improvement over time in RCC treated with nephrectomy by analyzing a longitudinal cohort using propensity score matching (PSM).We retrospectively reviewed 960 patients with RCC who underwent radical or partial nephrectomy between 1981 and 2018. Patients were divided into two groups according to the time of surgery (1981–1999 vs. 2000–2018). Using PSM, overall survival (OS), cancer‐specific survival (CSS), and recurrence‐free survival (RFS) were compared between the two groups.Overall, 255 and 705 patients underwent surgery in the earlier (1981–1999) and recent (2000–2018) eras, and PSM derived a matched cohort of 466 patients (233 patients per each group). All patients in the earlier era cohort received open surgeries, whereas about a half (47.4%) of patients in the recent era cohort received minimally‐invasive (laparoscopic/robotic) surgeries. After PSM, 137 (29.4%) patients developed recurrence, 105 (22.5%) died of RCC, and 113 (24.2%) died from other causes, with a median follow‐up period of 90 months. The recent era cohort had significantly longer OS, CSS, and RFS than the earlier era cohort.Patients with RCC treated in the recent era (2000–2018) showed significantly longer survival than those treated in the earlier era (1981–1999). The improved survival might be attributable to the prevalence of minimally‐invasive (laparoscopic/robotic) surgeries. [ABSTRACT FROM AUTHOR]

Background: While physicians are considered to be more susceptible to developing depressive symptoms, empirical data are lacking. The study aims to compare the risk of depressive symptoms between emergency physicians and the general population in China based on national data. Methods: This was a national cross-sectional study. 10 457 emergency physicians and 101 120 participants from the general population were investigated from July 2018 to August 2018 and January 2019 to February 2019, respectively. PHQ-9 was used to measure depressive symptoms, and a score ≥ 10 indicates major depression. Propensity score matching was adopted to balance the characteristics between emergency physicians and the general population. Multinomial logistic regression model was used to examine the association between occupational groups and the severity of depressive symptoms. Binary logistic regression model was performed to explore the risk factors of major depression among emergency physicians. Results: The prevalence of major depression among emergency physicians was 35.7%, whereas among the general population was 13.9%. Emergency physicians had a 3.65 times higher risk of major depression than the general population. And emergency physician was significantly associated with mild (OR: 3.12, 95% CI 2.95–3.30), moderate (OR: 4.94, 95% CI 4.60–5.30), moderately severe (OR: 9.48, 95% CI 8.61–10.44), and severe depressive symptoms (OR: 14.18, 95% CI 12.47–16.13) compared with none depressive symptoms. Even after matching, the results remained consistent. Factors associated with major depression among emergency physicians included bachelor degree or above (OR: 1.22, 95% CI 1.06–1.40), worked long years (OR: 1.26, 95% CI 1.08–1.46 for 1–5 years; OR: 1.56, 95% CI 1.32–1.84 for ≥ 6 years), experienced workplace violence (OR: 2.51, 95% CI 2.16–2.94), worked more night shifts per month (OR: 1.33, 95% CI 1.16–1.51 for 6–10 times; OR: 1.83, 95% CI 1.58–2.11 for ≥ 11 times), smoked (OR: 1.64, 95% CI 1.47–1.84), and effort-reward imbalance (OR: 4.18, 95% CI 3.62–4.85). Conclusions: Emergency physicians had a higher risk of depressive symptoms than the general population. There is a need for greater awareness of the mental health issues faced by emergency physicians. [ABSTRACT FROM AUTHOR]

Objective Patients and Methods Results Conclusions This study sought to compare the risks and outcomes associated with category I cesarean section procedures performed in the delivery room versus those performed in the operating room.The analysis included 126 singleton pregnant women who underwent inpatient delivery at the Second People's Hospital of Nanning between January 2021 and May 2024. Following propensity score matching, 21 cases were in the delivery room group, and 105 cases were in the operating room group. Parameters under investigation encompassed decision‐to‐delivery interval, incision‐to‐delivery interval, surgical duration, intraoperative blood loss, postoperative antibiotic duration, postoperative hospital stay length, postoperative fever incidence, adverse neonatal outcomes, and blood routine parameters.The decision‐to‐delivery interval was significantly shorter in the delivery room group than in the operating room group. Conversely, the delivery room group exhibited longer surgical durations, higher blood loss, prolonged postoperative antibiotic usage, extended hospital stays, and elevated white blood cell counts with statistical significance (p < 0.05). Nevertheless, no notable variations were observed between the groups in maternal and neonatal outcome indicators, such as adverse neonatal outcomes and postoperative fever rates.The outcomes suggest that the delivery room group showed increased risks compared with the operating room group, potentially indicating heightened vulnerabilities to bleeding and infection. Hence, it is advisable for patients to undergo surgery in the operating room unless the delivery room is equipped with sterile surgical facilities or in cases of urgent necessity.
