A fast second-order absorbing boundary condition for the linearized Benjamin-Bona-Mahony equation
Authors: Zheng Zijun , Pang Gang , Ehrhardt Matthias , Liu Baiyili 
Published: October 2023

Abstract
In this paper, we present a fully discrete finite difference scheme with efficient convolution of artificial boundary conditions for solving the Cauchy problem associated with the one-dimensional linearized Benjamin-Bona-Mahony equation. The scheme utilizes the Pad\'e expansion of the square root function in the complex plane to implement the fast convolution, resulting in significant reduction of computational costs involved in the time convolution process. Moreover, the introduction of a constant damping term in the governing equations allows for convergence analysis under specific conditions. The theoretical analysis is complemented by numerical examples that illustrate the performance of the proposed numerical method.

Published: October 2023

Abstract
Background
Intermittent exotropia is the most common childhood strabismus, typically developing in early childhood. Preschool-aged children often struggle to articulate their symptoms. Caregivers of these children play a vital role in monitoring visual health, interpreting emotions, and making medical decisions. However, there is limited research on the experiences of caregivers, particularly during the preschool years. This study explores the lived experiences, emotions, and disease management strategies of caregivers for preschoolers with intermittent exotropia.
Methods
A descriptive phenomenological approach was employed for this study. Semi-structured interviews were conducted with 15 caregivers of children aged 5–7 years diagnosed with intermittent exotropia. Participants were selected through purposive sampling from a medical center's ophthalmology clinic in Taiwan, and Giorgi's descriptive phenomenological method was utilized.
Results
The findings revealed that primary caregivers' experience of caring for preschool children with intermittent exotropia is akin to a process of "energy conversion." In this process, caregivers convert energy in different caring stage to help their children and themselves face adversity and get through this journey. This process encompassed six themes: "Awareness of differences," "Seeking answers," "Struggling with their own emotions," "Prioritizing the child's emotional well-being," "Worries," and "Rising to challenges."
Conclusions
This qualitative study represents the first of its kind in Asia, shedding light on the experiences of primary caregivers caring for children with intermittent exotropia. Caregivers face numerous challenges in providing care, and their emotions are diverse and complex. The impact on the child's well-being generates worry and fatigue. Nevertheless, over time, caregivers rise to these challenges and assist children in achieving satisfactory adaptation to the disease.
Environment influences the genetic structure and genetic differentiation of Sassafras tzumu (Lauraceae)
Authors: Liu Qian , Liu Xiang , Gong Xi , Guan Bicai 
Published: October 2023

Abstract
Background
Sassafras tzumu , an elegant deciduous arboreal species, belongs to the esteemed genus Sassafras within the distinguished family Lauraceae. With its immense commercial value, escalating market demands and unforeseen human activities within its natural habitat have emerged as new threats to S. tzumu in recent decades, so it is necessary to study its genetic diversity and influencing factors, to propose correlative conservation strategies.
Results
In this investigation, we employed genotyping-by-sequencing technology to scrutinize the genetic diversity and structure of 106 individuals of S. tzumu, carefully gathered from 13 naturally occurring habitats in China. The primary results could be summarized as follows: the genetic diversity of S. tzumu was inferior to those of most other woody plants. Moreover, S. tzumu exhibited a moderate level of genetic differentiation (FST=0.103), with the preponderance of genetic variation residing within populations (71%). Our findings unveiled that the 13 populations could be categorically classified into four distinct genetic clusters (K = 4). Notably, the populations from Mount Hengshan (HS) and Mount Shaoshan (SS) coalesced into a single genetic cluster, while the populations from Mount Lushan (LS) and Mount Meiling (ML) formed another genetic cluster, with the remaining two populations occupying unique genetic clusters. Utilizing the multiple matrix regression with randomization (MMRR) analysis method, we unveiled that genetic distance was concurrently influenced by both geographical distance and environmental distance (r = 0.57, p < .01). However, it was noteworthy that the regression coefficient of environmental distance was nearly threefold greater than that of geographical distance, thus underscoring the prominence of environmental distance in shaping genetic distance (βE = 0.46, p < .01; βD = 0.16, p < .01).
Conclusions
S. tzumu had a moderate level of genetic differentiation and low genetic diversity in our study. The environmental distance of S. tzumu had a greater impact on its genetic diversity than geographical distance. It is of utmost significance to formulate and implement meticulous management and conservation strategies to safeguard the invaluable genetic resources of S. tzumu.

Published: October 2023

Abstract
Background
Retention of new nurses has become a major challenge for medical institutions. Job embeddedness has been shown to be a good predictor of nurse turnover, but more details of it are rarely disclosed, especially among new nurses. This study aims to investigate the job embeddedness level of new nurses and to reveal the influence of the nursing work environment, head nurse leadership and presenteeism on job embeddedness in this population from a theoretical point of view.
Method
A cross-sectional multicentre study involving 436 participants from 10 cities and 33 hospitals was conducted over 4 months. Samples were selected using a two-stage convenience sampling method. A sequential mediation model performed with SPSS-PROCESS was used to analyse the relationships among the nursing work environment, head nurse leadership, presenteeism and job embeddedness.
Results
The job embeddedness of new nurses was moderate (25.33 ± 4.51), which is lower than that of senior nurses (t=-5.441, p < 0.001). The nursing work environment (r = 0.731, p < 0.01) and head nurse leadership (r = 0.632, p < 0.01) positively correlated with job embeddedness. Presenteeism (r=-0.349, p < 0.01) negatively correlated with job embeddedness. Nursing work environment can not only directly affect the job embeddedness of new nurses, but also indirectly affect it through the sequential mediating effect of head nurses' leadership and presenteeism (R2 = 0.535, F = 82.160, p < 0.001).
Conclusions
We call on managers to focus on the job embeddedness of new nurses within two years of entry. Managers should avoid the "embedding dilemma" when cultivating new nurses' job embeddedness. The pathway to excellence aims to improve nursing work environment, head nurse leadership and to avoid presenteeism to cultivate "active embeddedness" replace "forced embeddedness " in new nurses, so as to stabilize the new nurse team.

Abstract
Background Multidisciplinary therapy centered on antitumor drugs is indicated in patients with unresectable pancreatic neuroendocrine neoplasms (PNENs). However, the criteria for selection of optimal therapeutic agents is controversial. The aim of this study was to assess the malignancy of PNENs for optimal therapeutic drug selection.Methods 47 patients with PNENs who underwent surgery were reviewed retrospectively, and immunohistochemical characteristics, including expression of GLUT1, SSTR2a, SSTR5, Survivin, XIAP, and Caspase3 in the resected specimens, were investigated. Relapse-free survival (RFS) and overall survival (OS) were evaluated with regard to the characteristics using the Kaplan-Meier method and compared with the log-rank test.Results GLUT1 expression showed significant correlation with sex (p = 0.036) and mitotic rate (p = 0.048). Survivin and XIAP expression showed significant correlation with tumor size (p = 0.008 and 0.009), T factor (p = 0.014 and 0.009), stage (p = 0.028 and 0.045), and mitotic rate (p = 0.023 and 0.007). XIAP expression also significantly influenced OS (p = 0.044).Conclusions Survivin and XIAP correlated with grade of malignancy, and expression of XIAP in particular was associated with a poor prognosis. Expression of these proteins may be a useful indicator to select optimal therapeutic agents in PNENs.

Published: October 2023

Abstract
Objective:
The primary aim of this study was to examine the correlation between the time to surgery (TTS) and overall survival(OS)rates in stage I-III colon cancer patients in China.
Methods:
A retrospective cohort of 1188 consecutive patients with stage I-III CC who underwent radical resection between September 2008 and September 2017 was collected. The time to surgery(TTS) was defined as the interval between diagnosis and surgical intervention. The study primarily concentrated on OS contingent on distinct TTS thresholds (1 to 2 weeks, 3 to 4 weeks, and beyond 4 weeks). Both univariate and multivariate analyses were utilized to evaluate the prognostic implications of TTS.
Results:
The study incorporated 1188 patients (700 (58.90%) females and 488 (41.10%) males) with a mean age of 58.5 ± 11.88 years. The median (IQR) time to surgery was 10 (7 - 15) days. Patients with a TTS of 1 to 2 weeks had a 5-year overall survival rate of 82% (n = 866), compared to 90% (n = 282) for those with a TTS of 3 to 4 weeks (p = 0.003). Multivariable Cox-regression analyses indicated that a TTS exceeding 4 weeks bore no association with overall survival, whereas a TTS of 1 to 2 weeks emerged as a significant independent risk factor for decreased overall survival in the entire cohort (hazard ratio (HR), 1.93; 95% confidence interval: 1.28 - 2.62).
Conclusions:
The optimal timing for definitive resection in colon cancer is situated between 3 and 4 weeks subsequent to the initial diagnosisin China.

Abstract

Objective Given that the trial operation of CHS-DRG reform, the study aimed to explore how hospitals can manage diseases with strong technological reputation but suffer losses in DRG payments.
Methods Taking UPPP for OSA patients in Hospital C as an example, the study analyzed whether there were changes in cost reduction, cost structure, patient disease severity, and medical quality before and after payment reform.
Results Hospital C did not experience phenomena such as referral of difficult patients (CCI index, AHI index, and lowest SPO2 did not significantly decrease), staged surgery (hospitalization was not decomposed for patients requiring two surgeries for combined nasal diseases), increased costs for out-of-town medical insurance patients (out-of-town medical insurance patients significantly decreased), and reduced medical quality (recent efficacy and long-term benefits did not significantly change) during the reform. However, there were behaviors such as transferring preoperative examinations to outpatient clinics and controlling high-value medicine consumption.
Conclusions By adjusting clinical pathways and transferring costs to outpatient clinics, Hospital C actively responded to the losses of UPPP patients and achieved the expected goal of quality control, cost reduction, and efficiency improvement. However, under the pressure of actual losses, hospitals should establish a mechanism of hospital-physician-patient win-win situation, strengthen refined management within the hospital, and improve the financial data performance within the hospital. The medical security department should also actively explore DRG accurate payment and even value-based payment, to help hospitals achieve high-quality development rather than become a constraint.

Abstract
Pancreaticoduodenectomy procedures were performed early in young individuals, with a few days about the risk and survival after robotic pancreaticoduodenectomy.
Our goal was to report the results of robotic pancreaticoduodenectomy in patients older than 50 years.
Methods
Our patients were divided into two groups: younger patients (less than 50 years) and older patients (> 50 years). A total of 1110 patients were included in this study:1004 (90.5%) in the elderly group and 106 (9.5%) in the young group.
Results
In younger demographics, the prevalence of periampullary cancer is 32.1% as opposed to 76.5%.
2. Tumors biological (15.1% versus 3.6%).
3. Pseudocapillary and solid malignancies (9.4% and 1.0%, respectively).
4. The tissues soft of the pancreas (77.4% vs. 62.5%).
There was a higher prevalence of non-dilated (≤ 3 mm) ducts within the pancreas (77.4% vs. 46.3%) in the younger group.
6. Young people group's hospitalization was less (median, 16 vs. 20 days).
7- The younger group fared better after treatment for total periampullary cancers of the with a 5-year prognosis of 76.4% compared to 46.7% in the older category.
8. The results of the other surgeries didn't vary significantly.
Conclusions
Robotic pancreaticoduodenectomy is associated with favorable survival outcomes for periampullary cancer in younger people (<50 years) and equivalent surgical outcomes compared to older individuals (≥50 years). These outcomes show that robotic pancreaticoduodenectomy is safe and effective in a subset of pediatric patients.
Following pancreaticoduodenectomy, the number of juvenile robotic tumor adenocarcinomas

Published: October 2023

Abstract
A highly sensitive hydrogen gas sensor operating at room temperature made of macroporous silicon (MPS) coated with a thin NiO film was realized. Macroporous silicon (MPS) layer was shaped by electrochemical anodization on an n-type Si surface. Thereafter, p-type NiO film was deposited onto the MPS surface by electrodeposition method. The morphology of the NiO/MPS sample was characterized by scanning electron microscopy (SEM). Al electrical contacts for further measurements were deposited onto the structure NiO/MPS by evaporation technique under vacuum. Gas sensing performances were measured to various H2 concentrations ranging from 122 to 1342 ppm at room temperature. The results showed that electrical behaviour of synthesized NiO/MPS sensor is similar to that of diode which can be used to detect H2 gas at low concentrations which reveal high sensitivity, fast response and recovery times working at room temperature.

Published: October 2023

Abstract
Diabetic patients are at high risk of developing lacrimal gland dysfunction, and the antimalarial drug artesunate (ART) was recently used to treat type 1 diabetes mellitus. This study’s objective is to investigate the effect of ART on the rat exorbital lacrimal gland and eyeball tissues and tear secretion in a type 1 diabetic dry eye animal model. Forty rats were divided into five groups (8 rats/group): healthy control group (HC), diabetic group (DM), 50 mg/kg ART intervention diabetic group [DM + ART (50 mg/kg)], 100 mg/kg ART intervention diabetic group [DM + ART (100mg/kg)] and 6 U/ kg Insulin intervention diabetic group (DM + INS). External lacrimal gland and eyeball tissues were harvested and for histopathological examination, electronic microscopic examination, NFκB1, and TNF-α protein expression evaluation by immunohistochemistry and mRNA expression analysis by RT-PCR. Histopathological and ultrastructural changes suggest ART intervention has an improved structural effect. Protein expression of NFκB1 in DM + ART (100 mg/kg) group was decreased. TNF-α significantly decreased on DM + ART (50 mg/kg) and insulin group. We concluded that ART improves structural changes on lacrimal gland in diabetic rats. The present study provides further evidence that the therapeutic effect of ART on lacrimal gland of diabetic rats by decreased expression of NFκB1 and TNF-α.

Abstract
Background Perioperative analgesia can improve the quality of postoperative recovery in thoracoscopic patients. Nevertheless, traditional analgesic effects are not ideal. Therefore, we intend to afford a fresh approach to managing postoperative pain in patients by dint of probe into the efficacy and safety of local ozone injection.Methods The sequence marked 87 patients subject to downwards video-assisted thoracoscopic lobectomy, divided into the ozone group (n = 44) and control group (n = 43). Primary observation indexes included the resting pain visual analog scale at 6 h, 24 h, 48 h, and 72 h as well as the postoperative three-month simplified McGill pain questionnaire. The statistical software SPSS 20.0 was used to analyse the similarity and dissimilarity in data.Results The Visual Analogue Scale scores (6 h, 24 h, 48 h, 72 h) of the ozone group after surgery were allegedly lower than those of the control group (p < 0.01). However, there were no significant differences in the sensory item score and affective item score in Pain Rating Index, Visual Analogue Scale score, or Present Pain Intensity score between the two groups in the third month after surgery (p > 0.05).Conclusions Local ozone injection for video-assisted thoracoscopic pulmonary lobectomy effectively lowers postoperative pain scores, facilitates incision healing, reduces postoperative acute adverse reactions, and enhances patients' short-term quality of life after surgery. Therefore, local ozone injection through a surgical incision is practical, safe, and feasible for postoperative pain relief in patients undergoing thoracoscopic lobectomy.Trial Registration ChiCTR2000037691(http://www.chictr.org.cn/showproj.aspx?proj=59038)registered on 30/8/2020

Published: October 2023

Abstract
Background: Bangladesh had not previously experienced epidemics such as SARS or MERS, and it is clear that its public healthcare systems were not readily prepared for COVID-19 vaccine uptake.
Objective: The aim of this research was to evaluate the level of knowledge, attitudes, and practices concerning COVID-19 vaccination and its determinants in Chittagong District, Bangladesh.
Methods: This descriptive cross-sectional study of 2,882 men and women was conducted in Chittagong, Bangladesh, from October 2021 to April 2022.
Results: A total of 850 men and women’s information was obtained, of which Group A = 205 (24.12%) for men and women who had been vaccinated, and Group B = 645 (75.88%) for men and women who had not been vaccinated. There were group or independent variables that entered the equation for subgroup analysis. Sensitivity analysis showed that the majority of the men and women who had been vaccinated had a good level of knowledge, attitudes, and practices regarding COVID-19 vaccination with (OR=0.166, 95% CI: 0. 113~0.245) and (OR=0.191, 95% CI: 0. 113~0.245), respectively. In addition, most of the men and women who were unvaccinated had poor/bad levels of knowledge, attitudes, and practices regarding COVID-19 vaccination with (OR=0.228, 95% CI: 0.154~0.336) and (OR=0.239, 95% CI: 0.154~0.336), respectively. Most of the participants were aged between 40-49 years, were Muslims, had secondary school level of education, and were employed.
Conclusion: The results suggest that the epidemic has significantly increased the level of knowledge, attitudes, and practices concerning COVID-19 vaccination.
Validation of the Arabic version of the Gratitude Questionnaire (GQ-4) in a sample of non-clinical adults
Authors: Obeid Sahar 
Published: October 2023

Abstract
Background
Although gratitude is a culturally-sensitive construct, it has yet received very little research attention in Arab countries; hence hindering the understanding of its features, correlates, and cross-cultural specificities. To fill this gap, we sought to examine the psychometric properties of an Arabic translation of the 6-item Gratitude Questionnaire (GQ) in an Arabic-speaking sample of adults from the general population of Lebanon.
Method
We conducted a web-based survey including 601 participants (mean age 29.91 ± 12.61; 62.7% females). The forward-backward translation method was used for the translation and adaptation of the GQ-6 into the Arabic language.
Results
Findings indicated that a four-item version of the GQ achieved adequate fit statistics; with the removal of the two reverse-scored items 3 and 6. We found a McDonald Omega coefficient for the total 4-item GQ (GQ-4) scores of .88, thus attesting for the good reliability of the scale. Multiple-group Confirmatory Factor Analysis showed that the scale structure was invariant across male and female respondents at the configural, metric, and scalar levels. Females exhibited significantly higher gratitude scores compared to males. Finally, discriminant validity of the Arabic GQ-4 was evidenced through positive significant correlations with social support levels.
Conclusion
The Arabic adaptation of the GQ showed good psychometric qualities; suggesting that it is suitable for measuring people’s disposition toward gratitude in Arab backgrounds. Offering the Arabic GQ-4 as a brief, simple, cost-effective, valid, and reliable measure of gratitude to the Arabic-speaking community could help raise awareness about gratitude as a key component for achieving good mental health and wellbeing in Arab contexts.
