Social Reintegration Experiences of Young Adult Cancer Survivors

This study uses the Q methodology to investigate the subjective perceptions of social reintegration among cancer survivors in their 20s and 30s. We organised a Q population through a pilot study and interviews and finalised 40 Q sample items. For P sample representativeness, we used purposive sampling and selected 12 individuals by age and cancer type. After a Q sorting process, we conducted a key factor analysis using Ken-Q Analysis Desktop Edition. We identified four types of P samples based on their perceptions and noted the main characteristics of each type. We characterised Type 1 as “recovery of presence through social reintegration seeking”, Type 2 as “confusion in social reintegration due to social prejudices”, Type 3 as “psychosocial support in the process of social reintegration”, and Type 4 as “blessing in disguise for post-traumatic growth”. The results suggest a need for practical and institutional support reflecting cancer survivors’ characteristics by type. This study provides basic data that researchers could use to develop coaching and counselling services to support the social reintegration of cancer survivors in their 20s and 30s.

Does the type of aortic pathology affect periprocedural outcomes in patients undergoing thoracic endovascular aortic repair?

Aim: To examine whether the type of aortic pathology affects periprocedural outcomes in patients undergoing thoracic endovascular aortic repair (TEVAR). Material and Methods: This retrospective observational cohort study included 47 TEVAR patients in total. Based on the kind of aortic pathology, the patients were categorized into three groups: Group 1 (n=23) included patients with type B aortic dissection (TBAD), Group 2 (n=14) included patients with descending thoracic aortic aneurysm (DTAA), and Group 3 (n=10) included patients with thoracic aortic mural thrombus (TAMT). Preprocedural basic clinical features, procedural data, and postprocedural outcomes and complications were compared between the groups. Results: The study population consisted of 36 males and 11 females, with a mean age of 62.48±14.2 years. Most of the patients in Groups 1 and 2 were male (82.6% and 92.8%), while 40% of the patients in Group 3 were male, and this difference was statistically significant. Compared to patients in other groups, individuals in Group 2 were significantly older and exhibited a higher incidence of chronic obstructive pulmonary disease and coronary artery disease. Group 3 required thromboembolectomy more frequently during the postprocedural period. In terms of other postprocedural outcomes, complications and mortality, there were no significant differences between the groups. Conclusion: Our study demonstrated that the type of aortic pathology did not significantly influence periprocedural outcomes in patients undergoing thoracic endovascular aortic repair (TEVAR). The TEVAR procedure can be effectively performed in suitable patients with various pathologies of the descending thoracic aorta.

Effects of Temperature, Dissolved Oxygen Concentration, and Photosynthetic Photon Flux Density on the Growth of the Sea Bivalve Tridacna crocea in Combination with the Symbiotic Alga Zooxanthella

The sea bivalve clam Tridacna crocea inhabiting the shallow sea of tropical and subtropical zones lives with the symbiotic alga zooxanthella in its mantle. Zooxanthellae algae perform photosynthesis and supply nutrients to T. crocea. Recently, the abundance of T. crocea has decreased rapidly due to overfishing in coastal areas in Okinawa, Japan. T. crocea culture systems for mass production will contribute to the conservation of T. crocea and thus marine ecosystems. Environmental control methods for T. crocea culture have not been established because of a lack of knowledge about the appropriate environmental conditions for T. crocea growth. The present study was initiated to obtain basic data for developing environmental control methods for T. crocea land-based aquaculture. The effects of water temperature, dissolved oxygen concentration, and photosynthetic photon flux density (PPFD) on the O2 exchange rates of the symbiotic system of T. crocea and zooxanthella, which are indicators of photosynthesis and respiration in the system, and the effect of daily integrated PPFD on T. crocea growth were investigated. Basic knowledge was obtained for the development of optimal environmental control technology for T. crocea clam culture. The optimum water temperature and dissolved oxygen concentration for photosynthesis in this symbiotic system were 28 °C, 5–6 mgO2 L−1 and 500 μmol m−2 d−1, respectively. The optimum daily integrated PPFD for clam growth was 20 mol m−2 d−1.

Concept model and realization of object orientied system with metaprogramming

The purpose of the research is to develop a conceptual model of an object oriented system and implement it using a functional language with metaprogramming support. Methods. A conceptual model of an object oriented system was developed based on a dynamic object system with message passing and dynamic dispatch. The developed object oriented system includes functions for creating and deleting classes, creating and deleting object instances of a class, functions for working with object properties, functions for adding methods to a class and passing messages. Inheritance is also possible, when a child class will have the properties of the parent class and its own properties. Results. The object oriented system was implemented using a set of macros and helper functions. The basic data structure was a hash table with key access capabilities, which was also implemented using macros. When a class is created, an instance constructor is automatically generated, setting the initial values of the object’s fields. Inheritance is implemented as the inclusion of fields of a parent class in a child object. Polymorphism is implemented as dynamic dispatch: when processing a message, a handler method is searched. The resulting object oriented system, together with the hash table module, occupies 97 lines. Conclusion. As a result of the work, a conceptual model of an object oriented system was created and implemented, which includes the main functions of the object oriented programming paradigm. It has been shown that macros can be used to create a compact object oriented system without the need to add any new functions or capabilities to the functional language interpreter.

Structural Stability of Pseudo-Parabolic Equations for Basic Data

This article investigates the spatial decay properties and continuous dependence on the basic geometric structure. Assuming that the total potential energy is bounded and the homogeneous Dirichlet condition is satisfied on the side of the solution within the cylindrical domain, we establish an auxiliary function related to the solution. By extending the data at the finite end forward, we can establish the continuous dependence on the perturbation of base data.

Teachers’ Roles in Coping with School Violence from the Perspectives of Prospective Teachers: A Q Methodological Approach

This study explores prospective teachers’ perceptions of school violence and their role in addressing it. Using a mixed method called Q methodology, we quantitatively analyzed the subjective views of 37 prospective teachers. Based on 33 statements, the study categorizes teachers’ roles in managing school violence and analyzes the characteristics of each role type. The research results provide basic data for prospective teachers to develop their capabilities as experts in dealing with school violence. The study identifies the following three types of teachers: prevention-oriented (Type 1), reality-avoiding (Type 2), and legal-regulation-oriented (Type 3). Type 1 emphasizes that teachers can significantly prevent school violence and believes that trusting relationships between teachers and students are key to reducing school violence. Type 2 teachers tend to ignore school violence out of fear of harm, even though they acknowledge its seriousness. Type 3 emphasizes the strict enforcement of legal responsibilities and rules, believing that clear regulations and punishments are essential for reducing school violence. This study highlights the need for customized educational programs that reflect the characteristics of different teacher types in handling school violence. It suggests incorporating practical strategies for preventing and responding to school violence in teacher training, expanding mental-health education, and promoting cooperative conflict-resolution methods between students and teachers.

Predicting the prognosis of Wilms tumor by peripheral blood cells: a real-world study of more than 30years.

Despite established excellent treatment strategies for Wilms tumor (WT), effective prognostic evaluation methods were lacking. This study aims to examine prognostic factors for WT through real-world peripheral blood cell profiling. Basic data and pre-treatment laboratory indices from WT and non-WT children underwent Wilcoxon test analysis. Chi-square tests assessed the correlation between blood cells and the overall survival (OS) and event-free survival (EFS) of WT. Further the Log-rank test and multivariate Cox were used to identify independent prognostic factors for OS. Traditional accepted factors were included in multi-Cox and the nomogram was constructed to further validate the outcome. Blood cells significantly differed between WT and non-WT groups (P < 0.05). Univariate analysis revealed that NLR above 1.380, stage IV, M below 0.325 × 103/μL were linked with lower OS, and PLR below 94.632, LB above 3.570 × 103/μL, stage IV, M above 0.325 × 103/μL,age ≤ 3years were meaningful for higher EFS (P < 0.05). While in the multifactorial COX, only M (HR:0.220, HR95%CI: 0.080 ~ 0.620, P = 0.004 and HR: 0.437, HR95%CI: 0.202 ~ 0.947, P = 0.036, respectively) and stage IV (HR: 7.890, HR95%CI: 1.650 ~ 37.770, P = 0.010 and HR: 3.720, HR95%CI: 1.330 ~ 10.408, P = 0.012, respectively) were independent prognostic factors for OS and EFS. These two variables also were significant after including recognized risk factors, and were demonstrated the predictability via nomogram. OS and EFS were poorer in WT children with M below 0.325 × 103/μL, suggesting the potential as a prognostic predictor for WT.

Case Studies of Battery Energy Storage System Applications in the Brazilian Transmission System

This paper presents the preliminary results of studies aiming to use a battery energy storage system (BESS) in the Brazilian transmission system. The main objective of the BESS is to solve congestion problems caused mainly by the large increase in variable renewable generation in certain system areas. The studies were conducted based on actual forecasted system scenarios using a full representation of the electric grid available from the Brazilian system operator data base. In this work, only the steady-state modeling was considered as this may be the first stage in the assessment of a new technology. A qualitative economic comparison of the BESS application with other possible solutions to the congestion problems is also included.

Abstract 4114705: Clinical Predictors of Stress Induced Cardiomyopathy

Introduction: Stress Induced Cardiomyopathy is increasingly becoming more prevalent with increasing awareness about disease condition with annual incidence of 30 cases/100000 per year and an incidence of 1-2% in the patients presenting with acute coronary syndrome.[1] Physical and emotional triggers have been linked with occurrence of Stress induced Cardiomyopathy. Methods: We have obtained the National Readmission database for the year of 2020. We have used the ICD 10 code I51.81 for stress induced cardiomyopathy and found 10450 patients in the data base. Total 494 patients had cardiac arrest and 191 patients out of this 494 had died. We have used Binary logistic regression methods to find the odd ratio for physical and emotional risk factors for stress induced cardiomyopathy. Results: Grief disorder with an odd ratio of 7.2, followed by female gender with an odd ratio of 4.1, septic shock with an odd ratio of 3.3, Hemorrhagic stroke with an odd ratio of 1.73, ischemic stroke with an odd ratio of 1.72, depression with an odd ratio of 1.5, followed by asthma exacerbation with an odd ratio of 1.35 and seizure disorder with an odd ratio of 1.34 were among the few predictors for stress induced cardiomyopathy. Incidence of Cardiac Arrest was 4.7% and mortality rate of 1.8% was observed in the patients with stress induced Cardiomyopathy. Discussion: Extreme emotional and physical triggers like stroke, septic shock are among few significant risk factors for the stress induced cardiomyopathy.

Experience of Family Caregivers in Long-Term Care Hospitals During the Early Stages of COVID-19: A Phenomenological Analysis

Background/Objectives: This study investigated the experiences of inpatient family caregivers who experienced restrictions in meeting their family members owing to the changed visitation guidelines of long-term care hospitals during the early stages of the coronavirus disease 2019 (COVID-19). We aimed to deepen our understanding of the nature of these caregivers’ experiences. Methods: The participants were family caregivers of patients in long-term care hospitals during the early stages of the COVID-19 pandemic. We collected data from nine inpatient caregivers from April to July 2021. Individual interviews and data were analyzed using Colaizzi’s phenomenological method. Results: Participants’ experiences were classified into the following three themes: (1) a prison-like long-term care hospital bound by strict COVID-19 prevention rules; (2) growing affection for unreachable parents; and (3) adaptation to a new, safer daily life. Participants had difficulty communicating with their families living under quarantine conditions during COVID-19 due to non-face-to-face situations. However, amid the long-term COVID-19 situation, participants overcame these challenges through efforts to facilitate communication. Conclusions: The results of this study can be used as basic data to support the smooth communication between patients and caregivers in long-term care hospitals in the event of an infectious disease outbreak in the future, to alleviate emotional stress, and to minimize the weakening of families.

Abstract 4128352: Association Between G6PD Deficiency and Congenital Heart Disease Incidence and Hospital Outcomes

Background: G6PD deficiency classically presents with hemolytic anemia, but associations have been described with atherogenesis and coronary artery disease. There are limited data that also suggest a link between G6PD deficiency and the development of congenital heart disease (CHD). Hypothesis: We hypothesize a higher incidence of CHD among individuals with G6PD deficiency as well as worse hospital outcomes for those with CHD and G6PD deficiency. Methods: We reviewed the Vizient® Clinical Data Base (a national, administrative database) from 10/2019-3/2024 for admissions of individuals aged 0-25 years with ICD-10 codes for moderate to severe CHD with and without and G6PD deficiency (D55.0, D75.A) to calculate and compare CHD incidence. Additional data included: demographics, hospital outcomes and costs. Hospital outcomes were compared using t-tests for normally distributed data, Mann-Whitney U test for non-normally distributed data and χ 2 for categorical data. Results: There were 213,708 admissions of individuals with CHD and &lt;1% had G6PD deficiency; findings in Table 1. Of the 6,363 admissions with G6PD, 289 (4.5%) had CHD and of 11,179,670 without G6PD, 213,419 (1.9%) had CHD ( p &lt;0.001). Patients with CHD and G6PD deficiency had male predominance and more Blacks (consistent with known G6PD deficiency epidemiology), longer length of stay and higher hospital costs than those without G6PD deficiency (Table 1). Conclusions: This review of a national database shows a higher incidence of CHD in admissions with G6PD deficiency as well as worse hospital outcomes (longer length of stay, higher costs) for those with CHD and comorbid G6PD deficiency. There were demographic differences, but these reflect the typical inheritance of G6PD deficiency. While there may be potential interplay between race/ethnicity and these outcomes as well, further investigation is needed.

DurdusTools—An Online Genetic Distance Calculation Tool for Efficient Variety Testing in Durum Wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.)

The management of variety collections can be supported by integrating molecular data into Distinctness, Uniformity, and Stability (DUS) testing. DurdusTools is a genetic distance (GD) calculation tool that supports planning field trials in durum wheat. A commercially available single-nucleotide polymorphism (SNP) wheat microarray is used to profile varieties and candidate varieties. Their molecular profiles are stored in a database. SNP markers selected based on quality parameters are used to calculate the pairwise genetic distance (GD) between the varieties. Combining molecular and variety information creates a downloadable, user-friendly Excel-based output. The file shows the pairwise GD of the varieties most similar to the candidate variety of interest and selected variety information. After the first year of field trials, the DUS experts use the phenotypic assessment data together with the GD information to select genotypes to be grown in the field for side-by-side comparisons. The principles of DurdusTools allow for an easy integration of molecular data into DUS testing. Using the tool requires neither specific infrastructure nor molecular expert knowledge and was developed by its users for DUS testing purposes. This makes DurdusTools an easily accessible and user-friendly tool that supports variety selection for DUS field trials through an improved data basis.

The interplay of body mass index, gestational weight gain, and birthweight over 3800 g in vaginal breech birth: A retrospective study.

Optimal counseling of women for vaginal breech birth requires consideration of both established and emerging risk factors for adverse perinatal outcomes. Currently, rising prevalences of maternal obesity and impaired glucose tolerance challenge obstetric care. We aimed to investigate the effects of these parameters on the outcome of vaginal breech birth to improve counseling practices. A total of 361 women (without previous vaginal births) attending vaginal birth of a singleton fetus in breech presesntation between 01/2015 and 11/2021 were included in this retrospective single-center study. Data were derived from the hospital data base. We analyzed the effect of the maternal body mass index (BMI) at birth (compared to pre-pregnancy BMI), excessive weight gain, gestational diabetes, and neonatal birthweight on obstetrical and neonatal short-term outcomes (intrapartum cesarean delivery, performance of obstetric maneuvers (Løvset-, Bracht-, Veit-Smellie maneuver and Bickenbach's arm delivery), admission to the neonatal unit, Apgar score after 5 minutes<7, and arterial cord pH-value <7.10). Multivariable logistic regression was used for analysis and adjustment of variables. Overall, 246 women (68.1%) had a successful vaginal birth. Intrapartum cesarean delivery (n = 115/361; 31.9%) was independently associated with maternal BMI at birth (p = 0.0283, aOR = 1.87 (1.19-3.97)) if birthweight was ≥3800 g. The rate of intrapartum cesarean delivery was also higher in women with gestational diabetes (p = 0.0030, aOR = 10.83 (2.41-60.84)). A significantly higher risk of neonatal acidosis (arterial pH-value <7.10) was observed in women with BMI at birth ≥30 kg/m2 (p = 0.0345, aOR = 1.84 (1.04-3.22)) without affecting other outcomes. Pre-pregnancy BMI, gestational weight gain and BMI-gain did not significantly affect the obstetrical and neonatal birth outcomes. When neonatal birthweight is ≥3800 g, maternal BMI at birth (p = 0.0283; aOR = 1.87 (1.19-3.97)) is independently associated with the rate of intrapartum cesarean delivery. However, pre-pregnancy BMI and BMI-gain during pregnancy were not associated with the need for intrapartum cesarean delivery or other adverse outcomes. Consequently, BMI at the time of birth could be more informative than pre-pregnancy BMI and may improve counseling of women attempting vaginal breech birth.

Impacts of demographic factors and the COVID-19 pandemic on job stress inJapanese childcare workers.

Japan has a shortage of childcare personnel, and the high levels of stress causing turnover in childcare workers must be urgently resolved. However, there is a lack of knowledge regarding the characteristics and influencing factors of job stress in Japanese childcare workers. This study aimed to evaluate the job stress of childcare workers and explore the influence of demographic factors and the COVID-19 pandemic on such stress. The data were collected through an Internet survey from 2,472 respondents. A 23-item version of the Brief Job Stress Questionnaire was used to measure occupational stress in childcare workers. The instrument is recommended in the stress-check program implemented as a mental health measure in workplaces in Japan. The percentage of childcare workers with high stress exceeded that of general workers. Multiple regression analyses showed that the only factor affecting all job stressors and social support was the fear of contracting COVID-19. Job stressors and the COVID-19 pandemic had a significant large effect on stress responses. Additionally, being married and having children moderated childcare workers' stress. This study provided basic data regarding job stress in Japanese childcare workers and compared them with those of other professionals. In the future, it will be necessary to clarify how stress is related to turnover intention and turnover in Japanese childcare workers to promote their career continuity.

Characteristics of Solid Mineral Phase Transitions During Sulfuric Acid Production from Gaseous-Sulphur-Reduced Gypsum

The acid co-production of cement is a prominent research focus for the large-scale, high-value utilization of phosphogypsum in the context of dual-carbon strategies. This paper builds on extensive research conducted by its authors on the co-production of sulphoaluminate cement clinker through acid production from gaseous-sulphur-reduced phosphogypsum. The solid mineral phase transformations occurring in the kiln during this process are systematically studied, and the effects of various calcination regimes (temperature, time, and atmosphere) on the evolution of clinker mineral phases are elucidated. This paper provides basic data support for the gas-sulfur-reduced phosphogypsum-acid cogeneration of sulfoaluminate cement clinker processes, and promotes the realization of the large-scale high-value utilization of phosphogypsum resources. The generation of the clinker mineral phase anhydrous calcium sulphoaluminate (C4A3S̅) begins at 1100 °C. Increasing the calcination temperature and extending the calcination time promote C4A3S̅ formation. However, when the calcination temperature exceeds 1350 °C, C4A3S̅ decomposes, leading to the formation of low-activity C2AS. In a CO atmosphere, the main mineral phases in the clinker transform into C2AS and 12CaO·7Al2O3, owing to the decomposition of CaSO4, which inhibits C4A3S̅ formation. At calcination temperatures exceeding 1300 °C, a significant amount of C2AS appears in the calcined material, and 12CaO·7Al2O3 begins to form.

Effect of femoral prosthesis flexion angle on unicompartmental knee arthroplasty with mobile platform

ObjectiveTo investigate the effect of the flexion angle of a femoral prosthesis on the postoperative clinical outcome of patients with knee osteoarthritis who are undergoing unicompartmental knee arthroplasty.MethodsPatients were divided into three groups according to the flexion angle of the femoral prosthesis following unicompartmental knee arthroplasty. Group A comprised patients with a flexion angle of the femur prosthesis of less than 5°, Group B included those with a flexion angle of 5° to 10°, and Group C consisted of patients with a flexion angle of the femur prosthesis greater than 10°. The basic clinical data, visual analog scale (VAS) score, Hospital for Special Surgery (HSS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and knee range of motion (ROM) were subjected to statistical analysis and comparison between the groups.ResultsNo significant differences were observed in the basic data of the patients in each group. The ROM and VAS scores for the knee in the first month following unicompartmental knee arthroplasty in groups B and C were significantly greater than those in group A. The HSS scores for the knee joint in Group B indicated superior outcomes in the initial postoperative month and the third postoperative month, as evidenced by the WOMAC scores, which demonstrated a statistically significant difference between Group B and the other two groups within the six-month postoperative period.ConclusionThe short-term recovery of patients in Group B was the fastest. These results provide a new reference for the installation of femoral prostheses in unicompartmental knee arthroplasty.
