Purpose: This study is descriptive research aiming to identify factors influencing the stigma experienced by college students with coronavirus disease 2019 (COVID-19), focusing on COVID-19 pandemic stress, depression, and fear of negative evaluation as the main variables. Methods: An online survey was administered to 175 college students who had been diagnosed with COVID-19 from January to May 2022 and were enrolled in universities in Seoul, Cheongju, and Daegu, South Korea. The survey collected data on pandemic stress, depression, fear of negative evaluation, and stigma. The data were analyzed using the t-test, ANOVA, the Scheffé test, Pearson’s correlation coefficients, and stepwise multiple regression in SPSS/WIN 26.0. Results: We analyzed differences in stigma scores based on general characteristics of the college students and found significant differences in stigma scores by age, major satisfaction, interpersonal satisfaction, date of COVID-19 confirmation, treatment modality, and recent subjective health condition. Factors influencing stigmatization were identified as COVID-19 pandemic stress, depression, date of COVID-19 confirmation, treatment modality, recent subjective health condition, and major satisfaction, with an overall explanatory power of 37.6%. Conclusion This study is significant as it identifies emotional changes across various aspects of pandemic stress, depression, fear of negative evaluation, and stigma among college students who have been diagnosed with COVID-19. The findings of this study suggest the development of programs to reduce psychological distress and enhance mental health management skills among these students.

Purpose: This study aimed to systematically review studies on the effect of peer tutoring on pediatric nursing education for nursing students and identify its contents and characteristics. Methods: A comprehensive search was conducted from November to December 2023 across databases including PubMed, Embase, CENTRAL, CINAHL, ProQuest, and others. We included both published and unpublished literature in English or Korean. Three reviewers independently screened and selected eligible studies that involved undergraduate nursing students participating in peer tutoring programs focused on pediatric nursing education. We analyzed quantitative outcomes related to learning effects and learner responses. The quality of the studies was assessed using the revised Cochrane risk-of-bias tool for randomized trials and the risk of bias assessment tool for non-randomized studies. Results: Five studies were reviewed, encompassing randomized controlled trials, a non-randomized controlled trial, a cohort study, and a before-after study. These interventions were conducted in school settings or pediatric clinical environments and featured different forms of peer teaching: horizontal, near-peer, and reciprocal. The tutor-to-tutee ratios ranged from 1:3 to 1:36.5. The educational content covered nursing care for major neonatal diseases, communication skills, medication administration, and resuscitation techniques. Significant improvements in cognitive knowledge and communication skills were observed among nursing students. However, there was noticeable variability in the design and reporting of the studies. Conclusion Peer tutoring programs can effectively enhance pediatric nursing education by improving nursing students’ knowledge and skills. For future meta-analyses, more studies in this field reported according to reporting guidelines are needed.

Urinary incontinence (UI), affecting 3%-11% of males and 25%-45% of females globally, is expected to rise with an aging population. It significantly impacts mental health, causing depression, stress, and reduced quality of life. UI can exacerbate psychiatric conditions, affecting treatment compliance and effectiveness. Itis categorized into transient and chronic types. Transient UI, often reversible, is caused by factors summarized in the acronym DIAPPERS: Delirium, Infection, Atrophic urethritis/vaginitis, Psychological disorders, Pharmaceuticals, Excess urine output, Restricted mobility, Stool impaction. Chronic UI includes stress, urge, mixed, overflow, functional, and persistent incontinence. Drug-induced UI, a transient form, is frequently seen in psychiatric treatment. Antipsychotics, antidepressants, and other psychiatric medications can cause UI through various mechanisms like affecting bladder muscle tone, altering nerve reflexes, and inducing other conditions like diabetes or epilepsy. Specific drugs like lithium and valproic acid have also been linked to UI, though mechanisms are not al-ways clear. Managing UI in psychiatric patients requires careful monitoring of urinary symptoms and judiciousmedication management. If a drug is identified as the cause, options include discontinuing, reducing, or adjusting the dosage. In cases where medication continuation is necessary, additional treatments like desmopressin, oxybutynin, trihexyphenidyl, or amitriptyline may be considered.

Aortic dissection during cardiopulmonary bypass for aortic aneurysm surgery is a rare complication. If unrecognized in early time, it would be a fatal consequence. Neurological sequelae remain a well-recognized complication of cardiac surgery. Monitoring of cerebral oxygenation may be a useful technique for identifying vulnerable periods for the development of neurological injury. We report the experience of the decreasing left radial blood pressure and left rSO2 which caused by retrograde aortic dissection during the ascending aortic aneurysm replacement surgery.

OBJECTIVES: There are evidences of apoptotic neuronal cell death in Alzheimer's disease (AD). Recent studies suggested AD pathogenesis in the central nervous system as well as in peripheral lymphocytes. The object of this study is to compare the cell viability and the proliferation activity in AD patients with healthy normal control by using peripheral lymphocytes. METHODS: We analyzed the cell viability and the proliferation activity of phytohemagglutinin (PHA)-activated lymphocytes from 73 AD patients and 31 normal contols. The cell viability and the proliferation activity were measured at baseline (T0), 24 hours (T24), 48 hours (T48), 72 hours (T72), 96 hours (T96), by the tryphan blue method and the BrdU proliferation activity method, respectively. RESULTS: The cell viability of PHA-activated peripheral lymphocytes in AD patients was significantly decreased at T72, T96 compared with healthy controls (F=8.034, p<0.001). In AD patients, the decline of proliferation activity appeared in earlier than healthy normal controls. CONCLUSION: This study suggests that there is a decreased cell viability and the proliferation activity of peripheral lymphocytes in AD patients. These finding may be related with the increased apoptosis in Alzheimer's disease.

OBJECTIVE: Speedy surgical orthodontics (SSO), an innovative orthodontic treatment, involves the application of orthopedic forces against temporary skeletal anchorage devices following perisegmental corticotomy to induce movement of specific dental segments. Herein, we report the biological effects of SSO on the teeth and periodontal structures. METHODS: Five beagle dogs were divided into 2 groups and their 6 maxillary incisors were retracted en masse by applying 500 g orthopedic force against a single palatal mini-plate. Retraction was performed without and with perisegmental corticotomy in groups I and II, respectively. All animals were killed on the 70th day, and their periodontal structures were processed for histologic analyses and scanning electronic microscopy (SEM). The linear distance between the third maxillary incisor and canine was used as a benchmark to quantify the retraction amount. RESULTS: Retraction was markedly faster and retraction amount greater in group II than in Group I. Surprisingly, Group II did not show any root resorption despite extensive retraction, while Group I showed prominent root surface irregularities. Similarly, SEM showed multiple resorption lacunae in Group I, but not in Group II. CONCLUSIONS: SSO is an effective and favorable orthodontic approach for major en masse retraction of the maxillary anterior teeth.
