Density of Yang-Lee zeros for the Ising ferromagnet
The densities of Yang-Lee zeros for the Ising ferromagnet on the
square lattice are evaluated from the exact grand partition functions
(). The properties of the density of Yang-Lee zeros are discussed as
a function of temperature and system size . The three different classes
of phase transitions for the Ising ferromagnet, first-order phase transition,
second-order phase transition, and Yang-Lee edge singularity, are clearly
distinguished by estimating the magnetic scaling exponent from the
densities of zeros for finite-size systems. The divergence of the density of
zeros at Yang-Lee edge in high temperatures (Yang-Lee edge singularity), which
has been detected only by the series expansion until now for the square-lattice
Ising ferromagnet, is obtained from the finite-size data. The identification of
the orders of phase transitions in small systems is also discussed using the
density of Yang-Lee zeros.Comment: to appear in Physical Review

Development of a Postburn Pruritus Relief Protocol
Background Postburn pruritus is a syndrome of stressful symptoms that is pervasive and occurs in over 90% of burn patients and continues for years after the burn has healed. Postburn pruritus is experienced by burn survivors that may require medical management and effective interventions.
Purpose This article shows how to effectively relieve postburn pruritus by developing a postburn pruritus relief protocol.
Design A descriptive literature review was conducted, and relevant empirical articles written during the years 2000ā2014 were appraised to create a postburn pruritus relief protocol. Twenty-six of 79 articles were selected using preestablished inclusion criteria: any age group experiencing burn-related pruritus after second- or third-degree burns. Databases were Cochrane Central Register of Controlled Trials, CINAHL, EBSCO, PubMed, the National Guideline Clearinghouse, Google Scholar, and the American Burn Association website.
Conclusions This protocol included both nonpharmacological and pharmacological interventions that have been delineated for use and was developed to apply based on the healing stage: prehealing, healing, and posthealing

Nursing Students\u27 Willingness to Care for Older Adults
The older adult population has increased and is projected to grow. This population usually has chronic disorders that need continuous care. However, it has been reported nurses and nursing students have negative attitude towards older adults. This descriptive study aimed at investigating factors influencing nursing studentsā willingness to care for older adults. This study was conducted among 270 nursing students at the university in the United States from February 1 to February 28, 2017. Study participants answered the survey about quality and frequency of contact with older adults, anxiety about aging, empathy, attitude, and willingness to care for older adults. Tools in the study included; quality and frequency of contact with older adults; anxiety of aging scale; interpersonal reactivity index; attitude towards older adults; and willingness to care for older adults. The result showed factors influencing nursing studentsā willingness to care for older adults; the year (e.g. first, second, and third year) of nursing program, anxiety of aging, and empathy towards older adults. Therefore, this study recommends the nursing program be revised to improve nursing studentsā willingness to care for older adults by increasing empathy and quality of contact with older adults and decreasing anxiety about aging throughout the program

Building Confidence, Diminishing Stress: A Clinical Incivility Management Initiative for Nursing Students
Objective: The aim of this study was to evaluate the effectiveness of an interactive program designed to reduce nursing studentsā perceived stress and improve self-efficacy and readiness to professionally address incivility during clinical practice. Background: Incivility in clinical settings adversely impacts learners, educators, institutions, and healthcare systems, undermining safety and the teachingālearning process. Despite its increasing global prevalence, effective interventions remain largely unexplored. Methods: Our mixed-methods study, conducted from March to April 2024, involved senior baccalaureate pre-licensure nursing students (N = 35) from a California State University. The three-week, one-hour-per-week, interactive clinical incivility management program was developed through an extensive literature review. Pre- and post-intervention differences were assessed using a 10 min self-administered online survey that included the Uncivil Behavior in Clinical Nursing Education (UBCNE; 12 items), Perceived Stress Scale (PSS; 10 items), General Self-Efficacy Scale (GSE; 10 items), and a sample characteristics questionnaire (11 items). A one-hour face-to-face focus group (n = 11) then provided qualitative data on personal experiences of clinical incivility. Quantitative data were analyzed using SPSS version 27, while qualitative data were analyzed using Colaizziās method. Results: Clinical incivility prevalence was 71.4% (n = 25 out of 35). No statistically significant differences were found in UBCNE, PSS, and GSE scores between pre- and post-intervention. However, professional responses to clinical incivility significantly improved after the intervention (t = ā12.907, p \u3c 0.001). Four themes emerged from the qualitative data: (a) uncivil behaviors or language from nurses, (b) emotional discouragement and low self-confidence, (c) resource and personnel shortages at clinical sites for education, and (d) the necessity for interventions to manage clinical incivility. Conclusions: Nursing schools and clinical agencies should collaborate to establish monitoring systems, enhance communication, and implement evidence-based policies and interactive interventions to prevent and manage clinical incivility experienced by nursing students from clinical sites

Sex-associated differences in baseline urinary metabolites of healthy adults.
The biological basis for gender variability among disease states is not well established. There have been many prior efforts attempting to identify the unique urine metabolomic profiles associated with specific diseases. However, there has been little advancement in investigating the metabolomic differences associated with gender, which underlies the misconception that risk factors and treatment regimens should be the same for both male and female patients. This present study aimed to identify biologically-meaningful baseline sex-related differences using urine samples provided by healthy female and male participants. To elucidate whether urinary metabolic signatures are globally distinct between healthy males and females, we applied metabolomics profiling of primary metabolism with comprehensive bioinformatics analyses on urine samples from 60 healthy males and females. We found that levels of Ī±-ketoglutarate and 4-hydroxybutyric acid increased 2.3-fold and 4.41-fold in males compared to females, respectively. Furthermore, chemical similarity enrichment analysis revealed that differentially expressed metabolites, such as saturated fatty acids, TCA, and butyrates, were significantly related to the gender effect. These findings indicate that there are baseline sex-related differences in urinary metabolism, which should be considered in biomarker discovery, diagnosis, and treatment of bladder diseases, such as interstitial cystitis

The Effects of Fall Health Belief and Knowledge of Fall on the Prevention of Fall in the Elderly: Mediating and Moderating Effects of Fall Fear
Purpose: This descriptive study investigated the mediating and moderating effects of fear of fall on the relationships between health belief on fall, fall-related knowledge and fall prevention behaviors among older adults Methods: We enrolled 229 older adults residing in a senior citizen hall and community welfare center, and investigated their health belief on fall, fall-related knowledge, fall prevention behavior, and fear of fall. Descriptive statistics, ANOVA and t-test were used to analyze differences in variables. Pearson correlation and multiple regression were used to investigate mediating and moderating effects of the fear of fall on the relationships between health belief on fall, fall-related knowledge, and fall prevention behaviors. Results: The fear of fall significantly mediated the health belief on fall and fall prevention behaviors, but there was no significant mediation between knowledge of fall and fall prevention behaviors. The fear of fall did not have a moderating effect on the relationships between health belief on fall, knowledge of fall, and fall prevention behaviors. Conclusion: It is important to investigate and implement health belief on fall and fear of fall among older adults to improve their fall prevention behaviors

Risks for Depression Among Ostomates in South Korea
AIM:
This study explored the factors that are associated with the depressive status among older adult ostomates in South Korea. METHODS:
The study was a secondary analysis of data from a cross-sectional study with 217 ostomates who were aged ā„55 years from September 2, 2013 to October 30, 2013. The general characteristics, daily routines, and depressive status were assessed in order to identify the factors that were contributing to a depressed mood among the older adult ostomates in South Korea. The general characteristics included their sex, age group, educational level, financial status, employment, outing hours, perceived social isolation, leisure activity, and perceived health status. The daily routines included living environment inconvenience, leisure activity satisfaction, body image satisfaction, sleep satisfaction, exercise involvement, intimacy with a spouse, sexual satisfaction, and satisfaction with quality of life. RESULTS:
The prevalence of depressive status in older adult ostomates was 50.7%, but 40.8% in the same-age population without an ostomy. The factors that were associated with a depressed mood among the older adult ostomates in South Korea were social isolation, perceived poor health status, perceived low quality of life, dissatisfaction with leisure activities, and poor financial status. The participants\u27 sex, age, and educational level were not associated with depression. CONCLUSION:
Nurses need to encourage older adults with an ostomy to reduce their social isolation and to increase leisure activities by helping them to use resources, such as support groups and psychological support, in collaboration with interdisciplinary team members
