    Abstract Background: Hernias, particularly inguinal, femoral, and abdominal, present a global health challenge. While the global burden of disease (GBD) study offers insights, systematic analyses of hernias remain limited. This research utilizes the GBD dataset to explore hernia implications, combining current statistics with 2030 projections and frontier analysis.
    Methods: We analyzed data from the 2019 GBD Study, focusing on hernia-related metrics: prevalence, incidence, deaths, and disability-adjusted life years (DALYs) across 204 countries and territories, grouped into 21 GBD regions by the socio-demographic index (SDI). Data analysis encompassed relative change calculations, as well as annual percentage change (APC) and average annual percentage change (AAPC), both of which are based on joinpoint regression analysis. The study additionally employed frontier analysis and utilized the Bayesian age-period-cohort model for predicting trends up to 2030. Analyses utilized R version 4.2.3.
    Results: From 1990 to 2019, the global prevalence of hernia cases surged by 36%, reaching over 32.5 million, even as age-standardized rates declined. A similar pattern was seen in mortality and DALYs, with absolute figures rising but age-standardized rates decreasing. Gender data between 1990 and 2019 showed consistent male dominance in hernia prevalence, even as rates for both genders fell. Regionally, Andean Latin America had the highest prevalence, with Central Sub-Saharan Africa and South Asia noting significant increases and decreases, respectively. Frontier analyses across 204 countries and territories linked higher SDIs with reduced hernia prevalence. Yet, some high SDI countries, like Japan and Lithuania, deviated unexpectedly. Predictions up to 2030 anticipate increasing hernia prevalence, predominantly in males, while age-standardized death rates and age-standardized DALY rates are expected to decline.
    Conclusions: Our analysis reveals a complex interplay between socio-demographic factors and hernia trends, emphasizing the need for targeted healthcare interventions. Despite advancements, vigilance and continuous research are essential for optimal hernia management globally.

    Abstract Background: Hiatal hernias negatively damage patients' health and life quality. Laparoscopic hiatal hernia repair is currently the gold standard for the treatment of hiatal hernia (LHHR). Numerous clinical trials on laparoscopic hiatal hernia repair have been done, but the published findings are highly variable due to the lack of unique outcome sets. Basic outcome sets have ever been established over the previous decade for a few procedures, but not for hiatal hernia repair yet. This protocol outlines the procedure to develop a core outcome set for laparoscopic hiatal hernia repair COS-LHHR). COS-LHHR will provide a unique criteria for clinical investigations.
    Methods: This study will be conducted in four phases: (1) scoping reviews of existing qualitative studies and outcome reporting in randomized controlled trials to develop a list of potential outcome domains; (2) qualitative interviews with patients to explore the impact of laparoscopic hiatal hernia repair and the outcomes that they care most; (3) a multi-round e-Delphi study to achieve preliminary consensus on the core outcome set; and (4) an evidence-based consensus on a core outcome set will be achieved through a structured group consensus meeting, recommending best assessment outcome sets.
    Discussion: The development the COS-LHHR will guide clinical research of laparoscopic hiatal hernia repair with unique outcome assessment. This would improve comparative analyses among studies.

    Abstract Background: Inguinal, femoral, and abdominal hernia repairs are the most common surgical procedure worldwide. However, studies on hernia disease burden are notably limited, in both developed and low-income and middle-income countries (LMICs). We investigated temporal trends in the incidence and prevalence of inguinal, femoral, and abdominal hernias at global, regional, and national levels in 204 countries and territories from 1990 to 2019 using data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019).
    Materials and methods: Annual incident cases, prevalent cases, age-standardized incidence rates (ASIRs), and age-standardized prevalence rates (ASPRs) of inguinal, femoral, and abdominal hernias between 1990 and 2019 were extracted from the GBD 2019 study and stratified by sex, age, and location. Percentage changes in incident cases and prevalent cases, and the estimated annual percentage changes of ASIRs and ASPRs were calculated to quantify the trends in the incidence and prevalence of inguinal, femoral, and abdominal hernias. Data analysis for the present study was conducted from 15 June 2022 to 15 July 2022.
    Results: Globally, there were 32.53 million [95% uncertainty interval (UI): 27.71-37.79] prevalent cases and 13.02 million (10.68-15.49) incident cases of inguinal, femoral, and abdominal hernias in 2019, which increased by 36.00% and 63.67%, respectively, compared with 1990. Eighty-six percent of the incident cases were males, the male-to-female ratio was 6 : 1, and most patients were aged 50-69 years. India (2.45 million), China (1.95 million), and Brazil (0.71 million) accounted for more than one-third (39%) of the incident cases worldwide. From 1990 to 2019, the ASIR and ASPR showed a decreasing trend worldwide, except in Central Sub-Saharan Africa, which had an increasing trend in ASIR and ASPR.
    Conclusion: The global incident cases and prevalent cases of inguinal, femoral, and abdominal hernias increased substantially from 1990 to 2019, with a heavier burden observed in males, older adults, and in LMICs such as India and China. In addition, the ASIR and ASPR increased substantially in Central Sub-Saharan Africa. More efforts are warranted for hernia management to reduce the burden of inguinal, femoral, and abdominal hernias, such as by providing safe hernia surgical treatment for males, older adults, and LMICs.

    Abstract Background: The utilization of laparoscopic and open inguinal hernia repair in China remains unclear. We aim to investigate the rates of laparoscopic and open inguinal hernia repairs and its associated factors at a large hernia center.
    Methods: Data were obtained from the front sheet of medical records of Beijing Chaoyang hospital. Adult inguinal hernia inpatients who underwent hernia repairs between 2013 and 2020 were included. We calculated the overall rates of laparoscopic and open inguinal hernia repairs and compared the rate of laparoscopic repairs between different sex, age groups, types, and sides of inguinal hernias. Multivariable logistic regression was used to examine factors associated with the rate of laparoscopic repairs.
    Results: 14,481 inpatients with inguinal hernia were included. 91.78% were male, 75.43% were more than 50 years, 75.20% were unilateral inguinal hernia, and 64.57% were indirect inguinal hernia. Overall, 49.47% underwent laparoscopic repairs and 50.53% underwent open repairs. Women had lower rate of laparoscopic repair than men, especially in those with unilateral hernias. Bilateral and direct inguinal hernia had higher rates of laparoscopic repair than unilateral and indirect inguinal hernia. Multivariable logistic regression showed that inpatients who were women, > 70 years, pantaloon inguinal hernia, with obstruction, and more comorbidities were less likely to have laparoscopic repairs.
    Conclusion: Around 50% of inguinal hernia patients at a large hernia center underwent laparoscopic repairs, which was more commonly performed in male, young, bilateral inguinal hernia, and inpatients without comorbidities. More efforts were needed to increase the safe and effective laparoscopic utilization among female patients with inguinal hernias.

    Abstract Background: Water uptake is essential for seed germination. However, Gleditsia sinensis seeds have a water-impermeable seed coat, which is beneficial for its adaption to the environment, but prohibits its germination without treatment. This feature may be associated with the structure of the seed coat. Thus, the aim of this research was to identify and describe the initial water uptake site and water movement and to determine the relationship between seed coat structure and water absorption.
    Results: A water temperature of 80 °C was optimal to break the hardseededness of G. sinensis seeds. Scanning electron microscopy (SEM) images revealed that the seed coat consisted of a palisade layer and light line that can hinder water entry into the seed. Also, a structure of vascular bundles existed in the hilar region. Hot water treatment caused the tightly closed micropyle to open and the cavity beneath it expanded; the layer of palisade cells in the lens was raised. The embryo dye-tracking tests showed that the radicle tip was the initial region to be stained red. After staining for 24 h, the red-stained area on the vascular bundle side of cotyledon was more extensive than that on the other side. Further studies by MRI maps indicated that the micropyle was the initial site for water imbibition. Some water then migrated along the space between the seed coat and the endosperm to the chalazal; simultaneously, the rest of the water reached the embryonic axis and spread into cotyledons. The maps of 20-24 h showed that water was unevenly distributed within the cotyledons in a way that the edge parts were more hydrated than the center. Blocking tests showed that the hilar region was the initial and an important region during seed imbibition. The medial region and chalazal portion were capable of imbibing water when the hilar region was blocked, but water absorption was later and slower than that through the hilar region.
    Conclusion: MRI technology provides a promising and non-invasive technique to identify the water gap and the path of water movement in the seed. Combined with the results of SEM, the relation between seed coat and its imbibition can be inferred.

    Abstract Low temperature is one of the most prominent environmental factors affecting plant growth. As a deciduous arboreal tree, Acer palmatum has considerable ornamental and economic value; however, the molecular mechanisms underlying cold stress regulation in this species have yet to be determined. In this study, we performed Illumina high-throughput sequencing of 18 libraries obtained from A. palmatum subjected to cold treatment and subsequently identified a differentially expressed R2R3-MYB family gene, ApMYB77, which was then cloned and functionally characterized. The expression of ApMYB77 was induced by cold and drought treatments, and overexpression in A. thaliana enhanced the freezing tolerance (− 9 °C for 6 h) of transgenic plants compared with that of wild-type plants. The survival rates of transgenic plants (89% and 92%) were significantly higher than the wild-type plants (52%). Moreover, the transcript abundances of CBF-dependent regulatory pathway genes (AtCBF1, AtCBF2, AtCBF3, AtCBF4, AtCOR6.6A, AtCOR15B, AtCOR78, AtCOR414, and AtKIN1) were found to be significantly up-regulated in the transgenic lines. Enhanced abscisic acid (ABA)-dependent drought tolerance in transgenic plants was a further consequence of the overexpression of ApMYB77 following treatment of 15% polyethylene glycol for 4 d, compared with that in wild-type plants. In contrast, the expressions of genes (AtANAC072, AtDREB2A, AtERD1, AtMYB2, AtRD20, and AtRD29A) positively regulated by ABA were activated. Overall, the findings of this study indicate that ApMYB77 confers both freezing and drought tolerances.

    Abstract Two-dimensional (2D) half-metallic materials that have sparked intense interest in advanced spintronic applications are essential to the developing next-generation nanospintronic devices. Here we have adopted a first-principles calculation method to predict the magnetic properties of intrinsic, Se-doped, and biaxial strain tuning Cr$_2$AsP monolayer. The Janus Cr$_2$AsP monolayer is proved to be an intrinsic ferromagnetic (FM) semiconductor with a exchange splitting bandgap of 0.15 eV at the PBE+U level. Concentration-dependent Se doping such as Cr$_2$As$_{1-x}$Se$_x$P (x = 0.25, 0.50, 0.75) can regulate Cr$_2$AsP from FM semiconductor to FM half-metallicity. Specifically, the spin-up channel crosses the Fermi level, while the spin-down channel has a bandgap. More interestingly, the wide half-metallic bandgaps and spin bandgaps make them have important implications for the preparation of spintronic devices. At last, we also explore the effect of biaxial strain from -14% to 10% on the magnetism of the Cr$_2$AsP monolayer. There appears a transition from FM to antiferromagnetic (AFM) at a compressive strain of -10.7%, originating from the competition between the indirect FM superexchange interaction and the direct AFM interaction between the nearest-neighbor Cr atoms. Additionally, when the compressive strain to -2% or the tensile strain to 6%, the semiconducting Cr$_2$AsP becomes a half-metallic material. These charming properties render the Janus Cr$_2$AsP monolayer with great potential for applications in spintronic devices.
