Chronic inorganic nitrate supplementation does not improve metabolic health and worsens disease progression in mice with diet-induced obesity.

Inorganic nitrate (NO3-) has been proposed to be of therapeutic use as a dietary supplement in obesity and related conditions including the Metabolic Syndrome (MetS), type-II diabetes and metabolic dysfunction associated steatotic liver disease (MASLD). Administration of NO3- to endothelial nitric oxide synthase-deficient mice reversed aspects of MetS, however the impact of NO3- supplementation in diet-induced obesity is not well understood. Here we investigated the whole-body metabolic phenotype and cardiac and hepatic metabolism in mice fed a high-fat high-sucrose (HFHS) diet for up to 12-months of age, supplemented with 1 mM NaNO3 (or NaCl) in their drinking water. HFHS-feeding was associated with a progressive obesogenic and diabetogenic phenotype, which was not ameliorated by NO3-. Furthermore, HFHS-fed mice supplemented with NO3- showed elevated levels of cardiac fibrosis, and accelerated progression of MASLD including development of hepatocellular carcinoma in comparison with NaCl-supplemented mice. NO3- did not enhance mitochondrial b-oxidation capacity in any tissue assayed and did not suppress hepatic lipid accumulation, suggesting it does not prevent lipotoxicity. We conclude that NO3- is ineffective in preventing the metabolic consequences of an obesogenic diet and may instead be detrimental to metabolic health against the background of HFHS-feeding. This is the first report of an unfavorable effect of long-term nitrate supplementation in the context of the metabolic challenges of overfeeding, warranting urgent further investigation into the mechanism of this interaction.

The effects of longitudinal joint assembly imperfections on the internal forces in segmental linings

AbstractDuring the assembly of concrete segments into a tunnel lining, small geometric imperfections are unavoidable. In the longitudinal joints, they lead to contact deficiencies, which affect the eccentricities of the forces transferred through them. This influences the development of internal forces along the lining's circumference. However, it is often not realistically considered in structural calculations. In this paper, the effects of longitudinal joints assembly imperfections on the lining's internal forces were investigated by employing finite element models for various lining configurations. The results show that assembly imperfections have an unfavorable effect on the internal forces in most cases. Depending on the loading situation, this can lead to more required reinforcement and higher utilization ratios in the segments field and joints compared to perfectly assembled linings. Stiffer and less deformable configurations are at higher risk of experiencing more severe effects. In systems at risk, an individual assessment is recommendable. Therefore, a simplified method is introduced that requires a significantly reduced modeling effort and calculation time and lower software capabilities.

Social isolation during the covid-19 pandemic impaired vitamin d concentrations, motor performance and physical fitness in adolescents

This study aims to verify the effect of social isolation arising from the Coronavirus pandemic (COVID-19) severe acute respiratory syndrome (SARS-CoV-2) on vitamin D (25(OH)D) concentrations, motor performance, and cardiorespiratory fitness (CRF) in adolescents. This research method is Case-control study, which included 34 boys, aged 12-16 years. In the pre-pandemic period, 17 schoolchildren were evaluated in December 2019, classified according to body mass index Z-score (BMI-z) as: eutrophic (n=8) and overweight (n=9). The post-pandemic group was composed of 17 boys, evaluated in March 2022, matched with the same BMI-z characteristics. Stature, body mass, fat mass (FM), fat free mass (FFM), flexibility (FLEX), 25(OH)D, absolute CRF (CRFabs) and relative (CRFrel) were assessed. The Supine-to-Stand test (STSTIME) execution time was used to assess motor performance and motor competence by the motor patterns used in execution (STSMC). considering p<0.05 significant. The results showed that, post-pandemic, there were impairment on 25(OH)D, FLEX, STSTIME e CRF (p<0.05). Both eutrophic and overweight groups reduced 25(OH)D concentrations (p<0.001) and increased STSTIME (p=0.02) but did not modify STSMC. Regarding CRF, eutrophic individuals showed lower CRFabs and CRFrel values (p≤ 0.005), however no changes in the overweight group. We conclude that social isolation impaired the 25(OH)D concentrations and motor performance of adolescents. However, it stands out that the eutrophic were the most impacted with social isolation, as they showed unfavorable effect also on CRF.

Associations between sexuality, body image and health-related quality of life in patients treated for diffuse large B-cell lymphoma: A cross-sectional study

PurposeSexuality and body image are closely related to health-related quality of life (HRQoL), but these factors are less investigated in patients treated for lymphoma.Therefore, the aim of this study was to describe and explore the associations between sexuality, body image, comorbidities and HRQoL in patients treated for diffuse large B-cell lymphoma. MethodsA cross-sectional study with 257 patients (25% response rate) was conducted in 2019 using measures for sexuality, HRQoL and body image and data from the Swedish National Quality Registry for Leukemia–Subregistry for Lymphoma. ResultsThe participants had a mean HRQoL of 69.75 on a 1 to 100 scale, and the functional scales ranged from 68.50 for Role to 80.82 for Social functioning. The symptoms ranged from 5.56 for nausea and vomiting to 37.73 for fatigue. Regarding body image, the participants scored a total of 14.47 (reference values 10–40). The total score for Sexual adjustment was 3.02 (fair), and for the subscales Sexual Interest 2.63 (low), Sexual Relation 2.72 (low), Sexual Function 3.62 (high) and Sexual Satisfaction 3.50 (high). HRQoL was positively associated with Sexual Relation; however, negative body image and comorbidities showed negative associations. The model explains 39.6% of the variation in HRQoL. ConclusionThe positive impact of sexual relationships on HRQoL was highlighted, which emphasised the unfavourable effect of negative body image and comorbidities on HRQoL for lymphoma patients. Cancer nurses should address these topics with patients to improve their long-term well-being.

Clinical phenotyping and treatment response in patients with chronic heart failure: a latent class analysis from a Japanese multicentre registry

Abstract Background There are diversities of pathophysiology and co-morbidities in patients with chronic heart failure (HF), irrespective of left ventricular ejection fraction (LVEF). Therefore, the identification of subgroups with different outcomes and treatment response patterns may help to tailor strategies to each individual HF patient. Purpose We sought to identify phenogroups of patients with different prognosis and response to medical therapies in patients with chronic HF. Methods A total of 1565 patients with a broad spectrum of LVEF in a prospective multicentre registry of patients with chronic HF were enrolled between January 2020 and December 2023. Latent class analysis was performed in each subgroup using 80 features including patients’ demographics, laboratory, and echocardiographic data. The optimal number of phenogroups was determined using the first minimum of the Bayesian information criterion. The primary outcome was a composite of all-cause death and hospitalisation due to worsening HF. Results The analysis subclassified patients into six phenogroups. Patients in phenogroup A (young non-ischaemic cardiomyopathy, n = 242, 15.5%) were the youngest and had lower LVEF and lowest prevalence of coronary artery disease (CAD) and other comorbidities. Phenogroup B (atrial fibrillation [AF] and small left atrium, n = 282, 18.0%) had higher proportion of AF but smaller left atrium volume. Phenogroup C (ischaemic cardiomyopathy, n = 204, 13.0%) had the highest proportion of CAD and lower LVEF. Phenogroup D (classical HF with preserved ejection fraction [HFpEF], n =308, 19.7%) had the highest age, proportion of female, LVEF and thickness of LV wall. Phenogroup E (elderly and AF , n = 235, 15.0%) had higher age, the highest proportion of AF and largest left atrium volume. Phenogroup F (biventricular failure and multiple comorbidities, n = 294, 18.8%) had the highest proportion of co-morbidities and the lowest LVEF, right ventricular systolic function and renal function. During a median follow-up period of 538 (interquartile range 286-701) days, the incidence of the primary outcome significantly differed among the phenogroups (P < 0.001, Figure 1). Regarding treatment response for renin-angiotensin system blockers and beta blockers, there were no significant associations between the use of renin-angiotensin system blockers and the risk of the primary outcome among the phenogroups whereas the use of beta-blockers was significantly associated with increased risk of the primary outcome in patients classified to phenogroup D (classical HFpEF) (hazard ratio 1.83 95% confidence interval 1.05-3.19) among the phenogroups (Figure 2). Conclusion We identified six phenogroups with distinct clinical outcomes in patients with chronic HF, and the use of beta-blockers might have unfavorable effect in the classical HFpEF phenogroup. This phenotyping provides novel risk stratification and may aid in clinical decision making.Clinical outcomes among the phenogroupsTreatment effect among the phenogroups

The interplay of technology anxiety and digital health literacy in determining e-health readiness

Abstract Background The assessment of e-health readiness (eHR) is used to assess the ability of selected groups of citizens and patients, as well as society as a whole, to adopt e-health support. This study aimed to understand the main determinants of eHR in adult Internet users in Poland. Methods The analysis was conducted using data from a computer-based web-based interviewing (CAWI) survey carried out in June 2023 in a representative sample of 1661 Polish Internet users. The eHR score was established based on the e-Health Readiness Scale. Uni- (ULRM) and multivariable (MLRM) models were developed for eHR. Independent variables included technology anxiety (TA), digital health literacy (DHL), Internet (IU) and social media use (SMU), self-assessed health status, and sociodemographic variables. Results ULRMs revealed that TA, DHL, IU, SMU, an array of sociodemographic variables, and self-assessed health status (SAHS) were significant predictors of eHL. ULRMs with TA and DHL explained, respectively, 30.1% and 23.9% of the eHR variability. In MLRM developed with all predictors confirmed in ULRMs, only TA, DHL SMU, age, and income level maintained their significant effect on eHR. MLRM explained 42.8% of TA variability. Higher TA was associated with lower eHR (B, 95% confidentiality interval (95%CI): -0.30, -0.33 - -0.27). Respondents with higher DHL demonstrated higher eHR (B, 95%CI: 0.42, 0.37 - 0.48). Older persons were more likely to accept e-health solutions (B, 95%CI: 0.03, 0.003 - 0.05). More frequent SMU was associated with higher eHR (B, 95%CI: 1.87, 0.94 - 2.80). Finally, those who refused to reveal their level of income showed significantly lower eHR than those who revealed it (B, 95%CI: -0.84, -1.58 - -0.10). Conclusions TA and DHL are the main predictors of eHR. SMU also accounts for eHR. Unexpectedly, older age is a positive predictor of eHR. Finally, variables reflecting health status do not exert a significant effect on eHR. Key messages • Technology anxiety should be treated as an important determinant of the successful implementation of e health solutions. • The development of society’s digital health literacy may be a countermeasure to the unfavorable effect of technology anxiety on e-health readiness.

Non-consumable gamma-cyclodextrin additive constructing anti-solvation interphase realizing dendrites free and high-performance lithium metal batteries

Relying on surpassing high theoretical capacity (3,865 mAh/g) and the lowest relative electrode potential (0 V vs. metallic Li), lithium metal batteries (LMBs) have been regarded as the “holy grail” of next-generation energy storage technology. Whereases, the instability of pristine solid electrolyte interphase (SEI) layers and the disorderly growth of lithium dendrites are still significant challenges to the commercialisation of LMBs. In this study, a novel approach is introduced to homogenise Li deposition by incorporating an environmentally friendly electrolyte additive, gamma-cyclodextrin (γ-CD), in ether-based electrolytes. Through host-guest interactions, γ-CD additives not only form inclusion complexes to improve Li+ transference number to 0.86 but also encapsulate TFSI- anions and other solvent molecules within the “cavity effect” to relieve unfavourable solvent effect. Electrochemical characterisations demonstrate that introducing 1 wt% γ-CD elevates the oxidation decomposition voltage of ether electrolytes to 4.15 V, thereby inhibiting the decomposition of ether electrolytes and reducing the fracture of SEI layers. According to reduce the nucleate potential, the Li//Cu half battery exhibits improved stability for 100 cycles, with an improved average Coulombic efficiency (CE) maintained above 98.4 %. Even if applied at high current densities of 5.0 mA cm−2 for a capacity of 1.0 mAh cm−2, the Li//Li symmetric battery can cycle for over 800 h, and the Li//Li4Ti5O12 (LTO) full battery retains 98.8 % of the initial capacity after 1,400 cycles.

Assessment of inbreeding coefficients and inbreeding depression on complex traits from genomic and pedigree data in Nelore cattle.

Nelore cattle play a key role in tropical production systems due to their resilience to harsh conditions, such as heat stress and seasonally poor nutrition. Monitoring their genetic diversity is essential to manage the negative impacts of inbreeding. Traditionally, inbreeding and inbreeding depression are assessed by pedigree-based coefficients (F), but recently, genetic markers have been preferred for their precision in capturing the inbreeding level and identifying animals at risk of reduced productive and reproductive performance. Hence, we compared the inbreeding and inbreeding depression for productive and reproductive performance traits in Nelore cattle using different inbreeding coefficient estimation methods from pedigree information (FPed), the genomic relationship matrix (FGRM), runs of homozygosity (FROH) of different lengths (> 1Mb (genome), between 1 and 2Mb - FROH 1-2; 2-4 Mb FROH 2-4 or > 8 Mb FROH >8) and excess homozygosity (FSNP). The correlation between FPed and FROH was lower when the latter was based on shorter segments (r = 0.15 with FROH 1-2, r = 0.20 with FROH 2-4 and r = 0.28 with FROH 4-8). Meanwhile, the FPed had a moderate correlation withFSNP (r = 0.47) and high correlation withFROH >8 (r = 0.58)and FROH-genome (r = 0.60). The FROH-genome was highly correlated with inbreeding based on FROH>8 (r = 0.93) and FSNP (r = 0.88). The FGRM exhibited a high correlation with FROH-genome (r = 0.55)and FROH >8 (r = 0.51) and a lower correlation with other inbreeding estimators varying from 0.30 for FROH 2-4 to 0.37 for FROH 1-2. Increased levels of inbreeding had a negative impact on the productive and reproductive performance of Nelore cattle. The unfavorable inbreeding effect on productive and reproductive traitsranged from 0.12 to 0.51 for FPed, 0.19-0.59 for FGRM, 0.21-0.58 for FROH-genome, and 0.19-0.54 for FSNP per 1% of inbreeding scaled on the percentage of the mean. When scaling the linear regression coefficients on the standard deviation, the unfavorable inbreeding effect varied from 0.43 to 1.56% for FPed, 0.49-1.97% for FGRM, 0.34-2.2% for FROH-genome, and 0.50-1.62% for FSNP per 1% of inbreeding.The impact of the homozygous segments on reproductive and performance traits varied based on the chromosomes. This shows that specific homozygous chromosome segments can be signs of positive selection due to their beneficial effects on the traits. The low correlation observed between FPed and genomic-based inbreeding estimates suggests that the presence of animals with one unknown parent (sire or dam) in the pedigree does not account for ancient inbreeding. The ROH hotspots surround genes related to reproduction, growth, meat quality, and adaptation to environmental stress. Inbreeding depression has adverse effects on productive and reproductive traits in Nelore cattle, particularly on age at puberty in young bulls and heifer calving at 30 months, as well as on scrotal circumference and body weight when scaled on the standard deviation of the trait.

Funding Strategies used by Hispanic Churches in South Florida

The congregations in the United States need help with attendance. A decline in church membership results in a decrease in funds. This unfavorable effect on the institution's finances can affect the congregation's operations. This article seeks to assess and recommend a funding strategy for Hispanic Churches in South Florida. Correspondingly, Churches and other faith-based institutions require solid financial management to attain financial sustainment. Congregation administrators should focus on external and internal factors, financial planning, and developing and maintaining collaborations with external entities to grow their finances.

Calibration Method for Relativistic Navigation System Using Parallel Q-Learning Extended Kalman Filter.

For the relativistic navigation system where the position and velocity of the spacecraft are determined through the observation of the relativistic perturbations including stellar aberration and starlight gravitational deflection, a novel parallel Q-learning extended Kalman filter (PQEKF) is presented to implement the measurement bias calibration. The relativistic perturbations are extracted from the inter-star angle measurement achieved with a group of high-accuracy star sensors on the spacecraft. Inter-star angle measurement bias caused by the misalignment of the star sensors is one of the main error sources in the relativistic navigation system. In order to suppress the unfavorable effect of measurement bias on navigation performance, the PQEKF is developed to estimate the position and velocity, together with the calibration parameters, where the Q-learning approach is adopted to fine tune the process noise covariance matrix of the filter automatically. The high performance of the presented method is illustrated via numerical simulations in the scenario of medium Earth orbit (MEO) satellite navigation. The simulation results show that, for the considered MEO satellite and the presented PQEKF algorithm, in the case that the inter-star angle measurement accuracy is about 1 mas, after calibration, the positioning accuracy of the relativistic navigation system is less than 300 m.

Inhibiting the Formation of Toxic HCN Induced by C3H6 Coexistence and Enhancing C3H6 Resistance of Cu-Zeolite in the NH3-SCR Reaction.

The presence of light hydrocarbons (HCs) in diesel exhaust, specifically C3H6, significantly affects the performance of the state-of-the-art Cu-SSZ-13 zeolite NH3-SCR catalysts. It also leads to the formation of highly toxic HCN, posing risks to the environment and human health. In this work, the highly toxic HCN formation is inhibited, and the C3H6 resistance of Cu-SSZ-13 is improved by secondary metal modification via doping with rare earth/transition metal elements. Upon introduction of C3H6, the activity of Cu-SSZ-13 significantly decreases at medium-high temperatures. This is primarily due to the competitive reaction between C3H6 and NH3, which compete for the NH3 reductant required in the NH3-SCR reaction, resulting in the production of HCN. The unfavorable effect is alleviated on the modified catalysts due to their enhanced oxidation capabilities toward C3H6 and the HCHO intermediate, facilitating the complete oxidation of C3H6 to COx. This inhibits the undesirable partial oxidation reaction between C3H6 and NH3, thereby improving the activity of Cu-SSZ-13 at medium to high temperatures and significantly reducing the formation of highly toxic HCN.

A Dose-Response Study on the Relationship between White Meat Intake and Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) in Southern Italy: Results from the Nutrihep Study.

(1) Background: Metabolic dysfunction-associated liver disease (MASLD) is one of the most important causes of liver disease worldwide. Meat consumption is a growing trend and white meat has been shown to have beneficial effects on cardiometabolic risk factors. The aim of this study was to investigate the dose-response relationship between white meat intake and MASLD at survey level in a Southern Italy setting. (2) Methods: This cross-sectional study encompassed 1192 subjects (509 males, 42.7%) without missing data from the second wave of the NUTRIHEP cohort (2014-2016). Adjusted dose-response modeling was employed for statistical analysis; (3) Results: There were 587 subjects with MASLD (49.2%), i.e., 278 males (54.6%) and 309 females (45.2%). By increasing the intake, an unfavorable influence of white meat on MASLD was significantly revealed in females, whereas a protective effect of white meat was detectable in males. Male sex was shown to be involved in other associations in this study, such as influencing the preference for specific foods such as poultry and chicken skin. (4) Conclusions: Our data suggest that white meat does not have a clear-cut independent dose-response effect on MASLD, but sex may be a trigger moderator for age and BMI, with an increasing unfavorable effect of white meat in women, and a favorable effect in men.

Developing and validating a framework to explain cruise travel intention in the United States: a crisis management perspective

PurposeThis study aims to extend the cognitive appraisal theory by developing and validating a conceptual framework to illustrate how travelers' behavioral intention is generated via a multi-stage evaluation of health-related variables.Design/methodology/approachSEM and moderator analysis were conducted to examine the theoretical framework (post-intervention event travel intention) and to investigate how the appraisal process differs across travelers with various attitudes toward vaccination.FindingsThis study found that cruise travel intention was positively influenced by the perceived hedonic value and perceived trustworthiness and negatively influenced by perceived infection risk. Furthermore, whereas perceived hedonic value, perceived trustworthiness and perceived risk of infection were all predicted by crisis management, the dimensions of crisis management operated differently. In addition, vaccination attitudes amplified the unfavorable effect of perceived risk on intention.Originality/valueDrawing on the CAT, this study developed and validated a conceptual framework to integrate crisis management with customers' behavioral intentions. This study extends existing cruise travel intention theory by demonstrating how post-pandemic travelers' behavioral intention is generated via a multi-stage appraisal-reappraisal process based on the evaluations of infection risks and cruise line crisis management.

The Effect of High Hydrostatic Pressure (HHP) Induction Parameters on the Formation and Properties of Inulin-Soy Protein Hydrogels.

The aim of this study was to determine the effect of high hydrostatic pressure (HHP) induction parameters on the formation and properties of inulin-soy protein hydrogels. Solutions containing 20 g/100 g of inulin and 3 or 6 g/100 g of soy protein isolate (3 SPI; 6 SPI) were subjected to HHPs of 150, 300, or 500 MPa for 5, 10, or 20 min. The HHP parameters had no significant impact on the effectiveness of hydrogel formation. In most cases, the time of solution pressurization had no significant effect on the characteristics of hydrogels. However, increasing the induction pressure from 150 to 300 MPa resulted in hydrogels with different characteristics being obtained, e.g., more flattened microstructure; higher stability (only 3 SPI); higher yield stress, firmness, and adhesiveness; and lower spreadability. These changes were more noticeable in the hydrogels with lower protein content. An increase in the induction pressure (to 500 MPa) did not result in a significant strengthening of the hydrogel structure. However, in the case of 6 SPI hydrogels, induction with a pressure of 500 MPa had an unfavorable effect on their stability. The results indicate that HHP (300 MPa) can be used as an effective method for strengthening the structure of inulin-protein hydrogels.

Risk of mortality associated to chronic kidney disease in patients with complete left bundle branch block

Chronic kidney disease (CKD) is associated with cardiac conduction defects and is a strong risk factor for heart failure. Complete left bundle branch block (cLBBB), a cardiac conduction abnormality, may have an unfavorable effect on ventricular mechanical synchrony and lead to the progression of heart failure. Once heart failure develops, it seems to act together with underlying CKD in a vicious circle. Therefore, this study aimed to explore the influence of CKD in patients with cLBBB by assessing the estimated glomerular filtration rate (eGFR). We examined a hospital-based sample of 416 adult patients with cLBBB from 2010 to 2013. The eGFR was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Cox proportional hazard models were used to estimate the hazard ratio for all-cause mortality and cardiovascular mortality. A total of 416 adult patients with a mean age of 71 ± 13 years were enrolled. The median follow-up period was 3.6 years. After adjusting for clinical, electrocardiographic parameters, and medication use, cox regression analysis showed that total mortality was significantly associated with older age (Hazard Ratio (HR) = 1.03, 95% CI = 1.01–1.05, p = 0.002), presence of congestive heart failure (HR = 2.39, 95% CI = 1.63–3.49, p < 0.001), advanced CKD (HR = 2.48, 95% CI = 1.71–3.59, p < 0.001), higher HR (HR = 1.02, 95% CI = 1.01–1.03, p < 0.001) and without use of ACEI/ARB (HR = 0.59, 95% CI = 0.41–0.85, p = 0.005) were independent predictors of the total mortality. Multivariate Cox hazard regression analysis demonstrated that, in comparison to patients lacking cLBBB, the coexistence of CKD (eGFR < 60 mL/min/1.73 m2) among those with LBBB significantly heightened the risks of both total mortality (HR ratio of 5.01 vs. 2.40) and CV death (HR ratio of 61.78 vs. 14.41) even following adjustment for clinical covariates and ECG parameters. In summary, within patients exhibiting cLBBB, the presence of CKD serves as a significant risk factor for all-cause mortality.

Update: Neuromuscular Blockade during General Anesthesia

The correct use of muscle relaxants and neuromuscular monitoring during anesthesia has been subject of controversial discussions for decades. Particularly important in clinical practice are identification and management of residual neuromuscular blockages and avoidance of associated complications. Despite the differences in the molecular mechanisms of action between depolarizing and non-depolarizing muscle relaxants the blockade of the postsynaptic nicotinic acetylcholine receptor remains a common ending pathway. Due to its unfavorable side effect profile, succinylcholine should only be used in justified exceptional cases. The use of muscle relaxants generally reduces the complication rate in airway management. However, even the single use of muscle relaxants increases the likelihood of postoperative pulmonary complications. These complications associated with the use of muscle relaxants, such as residual neuromuscular blockade, must be anticipated. The application of guideline-based approaches, including continuous neuromuscular monitoring and the application of muscle relaxant reversal agents, may significantly reduce the rate of adverse events associated with the use of muscle relaxants.

Emergency Resection for Colonic Cancer Has an Independent and Unfavorable Effect on Long-Term Oncologic Outcome

BackgroundLong-term outcomes in patients undergoing emergency versus elective resection for colorectal cancer (CRC) remain controversial. This study aims to assess short- and long-term outcomes of emergency versus elective CRC surgery.MethodsIn this single-center retrospective cohort study, patients undergoing emergency or elective colonic resections for CRC from January 2013 to December 2017 were included. Primary outcome was long-term survival. As secondary outcomes, we sought to analyze potential differences on postoperative morbidity and concerning the oncological standard of surgical resection. The Kaplan-Meier curves and Cox proportional hazard model were used to compare survival between the groups.ResultsOverall, 225 CRC patients were included. Of these 192 (85.3%) had an elective and 33 (14.7%) an emergency operation. Emergency indications were due to obstruction, perforation, or bleeding. Patients in the emergency group had higher ASA score (p = 0.023), higher Charlsson comorbidity index (CCI, p = 0.012), and were older than those in the elective group, with median age 70 (IQR 63–79) years and 78 (IQR 68–83) years, for elective and emergency, respectively (p = 0.020). No other preoperative differences were observed. Patients in the emergency group experienced significantly more major complications (12.1% vs. 3.6%, p = 0.037), more anastomotic leakage (12.1% vs. 1.6%, p = 0.001), need for reoperation (12.1% vs. 3.1%, p = 0.021), and postoperative mortality (2 patients vs. 0, p < 0.001). No differences in terms of final pathological stage, nor in accuracy of lymphadenectomy were observed. Overall survival was significantly worse in case of emergency operation, with estimated median 41 months vs. not reached in elective cases (p < 0.001). At the multivariate analysis, emergency operation was confirmed as independent unfavorable determinant of survival (with hazard rate HR = 1.97, p = 0.028), together with age (HR = 1.05, p < 0.001), postoperative major morbidity (HR = 3.18, p = 0.012), advanced stage (HR = 5.85, p < 0.001), and need for transfusion (HR = 2.10, p = 0.049).ConclusionPostoperative morbidity and mortality were increased in emergency versus elective CRC resections. Despite no significant differences in terms of accuracy of resection and pathological stages, overall survival was significantly worse in patients who underwent emergency procedure, and independent of other determinants of survival.

Assessing different metrics of pedigree and genomic inbreeding and inbreeding effect on growth, fertility, and feed efficiency traits in a closed-herd Nellore cattle population

BackgroundThe selection of individuals based on their predicted breeding values and mating of related individuals can increase the proportion of identical-by-descent alleles. In this context, the objectives of this study were to estimate inbreeding coefficients based on alternative metrics and data sources such as pedigree (FPED), hybrid genomic relationship matrix H (FH), and ROH of different length (FROH); and calculate Pearson correlations between the different metrics in a closed Nellore cattle population selected for body weight adjusted to 378 days of age (W378). In addition to total FROH (all classes) coefficients were also estimated based on the size class of the ROH segments: FROH1 (1–2 Mb), FROH2 (2–4 Mb), FROH3 (4–8 Mb), FROH4 (8–16 Mb), and FROH5 (> 16 Mb), and for each chromosome (FROH_CHR). Furthermore, we assessed the effect of each inbreeding metric on birth weight (BW), body weights adjusted to 210 (W210) and W378, scrotal circumference (SC), and residual feed intake (RFI). We also evaluated the chromosome-specific effects of inbreeding on growth traits.ResultsThe correlation between FPED and FROH was 0.60 while between FH and FROH and FH and FPED were 0.69 and 0.61, respectively. The annual rate of inbreeding was 0.16% for FPED, 0.02% for FH, and 0.16% for FROH. A 1% increase in FROH5 resulted in a reduction of up to -1.327 ± 0.495 kg in W210 and W378. Four inbreeding coefficients (FPED, FH, FROH2, and FROH5) had a significant effect on W378, with reductions of up to -3.810 ± 1.753 kg per 1% increase in FROH2. There was an unfavorable effect of FPED on RFI (0.01 ± 0.0002 kg dry matter/day) and of FROH on SC (-0.056 ± 0.022 cm). The FROH_CHR coefficients calculated for BTA3, BTA5, and BTA8 significantly affected the growth traits.ConclusionsInbreeding depression was observed for all traits evaluated. However, these effects were greater for the criterion used for selection of the animals (i.e., W378). The increase in the genomic inbreeding was associated with a higher inbreeding depression on the traits evaluated when compared to pedigree-based inbreeding. Genomic information should be used as a tool during mating to optimize control of inbreeding and, consequently, minimize inbreeding depression in Nellore cattle.

Does ESG disclosure enhance firm performance during COVID-19? Evidence from Nifty 500 firms

Market turmoil caused by COVID-19 has weakened firms’ financial performance, highlighting the prominence of sustainable business practices by incorporating Environmental, Social, and Governance performance and their disclosure. Though past studies investigated COVID-19’s impact on firm performance, there is consensus on the role of firms’ Environmental, Social, and Governance disclosures between firm performance and the pandemic. With this view, the study aims to examine the impact of COVID-19 on firms’ financial performance with the moderating role of Environmental, Social, and Governance performance disclosure. To do so, the study retrieved data of Nifty 500 index companies from the Bloomberg database for a sample period ranging from 2016 to 2022. To this end, the study performed the fixed-effect regression and GMM model. The findings reveal a significant negative impact of the pandemic on Return on Assets (β =-4.812), Return on Equity (β =–.675), and Earnings Per Share (β = –2.875), highlighting the unfavorable effect of the pandemic on firm performance. Further results showed that firms’ Environmental, Social, and Governance performance disclosure positively moderates the connection between COVID-19 and Return on Assets (β = 3.231), Return on Equity (β = 0.032), and Earnings Per Share (β = 1.523), respectively. This indicates that companies actively involved in Environmental, Social, and Governance disclosure are less likely to suffer during the pandemic in terms of financial performance due to their ESG disclosures.

Banking concentration, information sharing and women's political empowerment in developing countries

PurposeThis article analyses the effect of bank concentration on women's political empowerment in 80 developing countries over the period 2004–2020.Design/methodology/approachBanking concentration (BC) is measured by the assets held by the three largest commercial banks as a percentage of total commercial bank assets in a country. We use several indices to measure political empowerment, namely: the political empowerment index, composed of three indices (i.e. the women's civil liberties index, the women's participation in civil society index and the women's political participation index). The empirical evidence is based on the Ordinary Least Squares (OLS) and Fixed Effects (FE) techniques.FindingsThe following findings are established. Banking concentration reduces women's political empowerment. Furthermore, information sharing offices (i.e. public credit registries and private credit bureaus) mitigate the negative effect of bank concentration on women’s political empowerment. Information sharing thresholds that are needed to completely dampen the negative effect of bank concentration on women’s political empowerment are provided. Policy implications are discussed, notably: (1) that governments in developing countries increase competition by easing barriers to entry for potential banks, to facilitate the transition from confiscatory concentration to distributive concentration favorable to all stakeholders; and (2) information sharing offices should be consolidated beyond the established thresholds in order to completely crowd-out the unfavorable effect of bank concentration of women’s political empowerment.Originality/valueThe paper provides new empirical evidence that helps to advance the debate on the effects of banking concentration and information sharing in the banking sector on women's political empowerment in developing countries.
