In addition to cellular damage, ischemia-reperfusion (IR) injury induces substantial damage to the mitochondria and endoplasmic reticulum. In this study, we sought to determine whether impaired mitochondrial function owing to IR could be restored by transplanting mitochondria into the heart under ex vivo IR states. Additionally, we aimed to provide preliminary results to inform therapeutic options for ischemic heart disease (IHD). Healthy mitochondria isolated from autologous gluteus maximus muscle were transplanted into the hearts of Sprague–Dawley rats damaged by IR using the Langendorff system, and the heart rate and oxygen consumption capacity of the mitochondria were measured to confirm whether heart function was restored. In addition, relative expression levels were measured to identify the genes related to IR injury. Mitochondrial oxygen consumption capacity was found to be lower in the IR group than in the group that underwent mitochondrial transplantation after IR injury (p < 0.05), and the control group showed a tendency toward increased oxygen consumption capacity compared with the IR group. Among the genes related to fatty acid metabolism, Cpt1b (p < 0.05) and Fads1 (p < 0.01) showed significant expression in the following order: IR group, IR + transplantation group, and control group. These results suggest that mitochondrial transplantation protects the heart from IR damage and may be feasible as a therapeutic option for IHD.

Background: Loss of companion animals can result in various psychological reactions, including complicated grief, depression, anxiety, and insomnia. However, research on the prevalence of patients requiring clinical intervention is limited. Moreover, research examining the relationship between childhood trauma and psychological symptoms after pet loss is lacking. Therefore, this study aimed to investigate the rates of clinically significant psychological distress after pet loss and the impact of childhood trauma on adults who have experienced pet loss. Methods: An online survey was conducted with non-clinical adult participants who had experienced the loss of a companion animal. Psychiatric characteristics were evaluated using standardized assessments, including the Inventory of Complicated Grief (ICG), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7), and the Insomnia Severity Index (ISI). Childhood trauma was evaluated using the Childhood Trauma Questionnaire (CTQ). Results: In a sample of 137 individuals who had experienced pet loss, the percentages of those who exceeded the cutoff points were 55% for the ICG, 52% for the PHQ-9, 40% for the GAD-7, and 32% for the ISI. The group that reported childhood trauma exhibited significantly higher scores on the ICG (t = 2.16, P = 0.032), PHQ-9 (t = 3.05, P = 0.003), GAD-7 (t = 2.61, P = 0.010), and ISI (t = 2.11, P = 0.037) than in the group without childhood trauma.For participants who experienced pet loss for less than one year, there was no significant difference in the ICG between the trauma and non-trauma groups, as both had extremely high scores. However, the trauma group had a significantly higher PHQ-9 (t = 2.58,P = 0.012) than the non-trauma group. In contrast, for participants who experienced pet loss for more than one year, the trauma group had a significantly higher ICG (t = 2.22, P = 0.03) than the non-trauma group, while there was no significant difference in the PHQ-9. Additionally, the emotional abuse scores on the CTQ were most significantly correlated with the ICG scores even after controlling for depressive symptoms. Conclusion People who experienced pet loss had significant psychological symptoms, ranging from 32% to 55%. Childhood trauma experiences affect complicated grief, depressive symptoms, anxiety symptoms, insomnia and prolonged grief disorder after pet loss. After pet loss, people with childhood trauma may require more psychological help than those without trauma.

Fecal incontinence (FI) undoubtedly reduces quality of life and adversely affects the social life of the affected individual. FI has a higher prevalence with age and has an equivalent prevalence to urinary incontinence in patients with genitourinary disease, but is often not confirmed in these cases. A thorough investigation is needed to diagnose FI, with the common etiology of this condition in mind, and several questionnaires can be used to identify symptoms. The physical examination contains digital rectal examination carries out to identify the patient’s condition. Ultrasound, colonoscopy, and rectum pressure test can be performed. Patients educated in diet-related issues, bowel movements, and defecation mechanism. Nonoperative options such as diet control and Kegel exercise should be performed at first. Surgical treatment of FI is considered when conservative management and oral medications produce no improvement. Surgical options include less invasive procedures like bulking agent injections, and more involved approaches from sacral nerve stimulation to invasive direct sphincter repair and artificial bowel sphincter insertion. Good outcomes in FI cases have also recently been reported for barrier devices.

Objectives: Adolescent suicide is a serious national issue in Korea. Recently, life satisfaction has been recognized as a major factor related to this issue. The main purpose of this study was to identify the domains of life satisfaction that affect suicidal behavior in adolescence. Methods: Data were collected from eight middle schools in Incheon, Korea. A total of 1297 students answered questions regarding their demographic characteristics, happiness, self-related life satisfaction domains (appearance, leisure time, physical health, and mental health), depressive symptoms, and suicidal behavior. Results: In the Spearman correlation analysis, female sex, perceived socioeconomic status (SES), happiness, and all four self-related satisfaction scores showed significant correlations with depression and suicidality. Multivariate regression analysis suggested that suicidality was significantly affected by perceived SES, satisfaction with appearance, mental health satisfaction, and depression. Finally, depression was identified as a partial mediator of the association between mental health satisfaction and suicidality, and a complete mediator of the association between female sex and suicidality. Conclusion Perceived SES, satisfaction with appearance, and mental health satisfaction significantly affected students’ suicidality, with or without the effect of depression. Health authorities, educators, and family members must be aware of this to identify adolescents at suicide risk earlier.

Objectives: Adolescent suicide, a major cause of adolescent death, is affected by various factors, including attitudes toward suicide.This study investigated the association between parenting style and adolescents’ attitudes toward suicide and the mediating role of attitude toward suicide between parenting style and suicidal ideation. Methods: We surveyed 1,071 adolescents from eight middle schools in Incheon, Korea. The survey included sociodemographic information, attitudes toward suicide, perception of parenting style, depression severity, and suicidality. Results: Students in the authoritarian parenting group had a more permissive attitude toward suicide compared with the democratic and permissive parenting groups. These students considered that suicide is justified in certain situations and that choosing suicide is an individual’s right. They also had a negative attitude toward talking about suicide or intervening in others’ suicide. This association remained statistically significant after adjusting for the impact of confounding factors that could affect attitudes toward suicide, except for suicidal processes and preparedness to prevent suicide. In the mediation analysis, we observed that some factors of the attitudes toward suicide mediated between authoritarian parenting attitudes and suicidal ideation, namely, suicide as a right, preventability, suicide as normal/common, preparedness to prevent suicide, and resignation. Conclusion This study revealed the significant impact of parenting style on children’s attitudes toward suicide. Educating parents about the appropriate parenting attitudes–sympathetic and rational–can help prevent youth suicide.

Background: Infrabrow blepharoplasty has become a common surgical method used to rejuvenate aged upper eyelids in Asians. In this paper, we describe the parallel excision method for infrabrow blepharoplasty as a useful alternative to the conventional elliptical excision method. The authors’ experience over a 3-year period is presented and reviewed. Methods: A retrospective review of parallel excision infrabrow blepharoplasty cases at our hospital between 2014 and 2017 was performed. Three oculoplastic surgeons compared preoperative and postoperative photographs using the Strasser grading system. Results: From the medical records of 123 patients, a total of 93 patients with moderate-to-severe bilateral dermatochalasis were selected as subjects. The exclusion criterion was levator function less than 8 mm. The total mean follow-up period was 2 years (range, 0.5–3.5 years). The mean skin excision height and width were 9.75 mm (range, 5–16 mm) and 58.51 mm (range, 42–75 mm), respectively. All patients who underwent surgery recovered without major complications, and all patients had high levels of satisfaction and improvements in their visual field. In the Strasser evaluation performed by the oculoplastic surgeons, most patients were found to have excellent results. Conclusions The parallel excision method for infrabrow blepharoplasty is a safe and effective technique that yields more natural- and youthful-looking eyelids than the conventional elliptical excision method. In our method, more effective manipulation of the orbicularis oculi muscle led to a reduction in frontalis compensation, resolution of sunken eyelids, and correction of lateral hooding.

BACKGROUND AND PURPOSE: A substantial proportion of patients with atrial fibrillation (AF) are not treated optimally; however, the inappropriateness of drug therapy has never been evaluated before or after a stroke event. We investigated the adherence to guidelines for therapy in AF patients hospitalized with acute ischemic stroke (AIS) before stroke onset and at discharge, with the aim of identifying the factors associated with inappropriate therapy. METHODS: AIS patients with AF hospitalized within 7 days of onset were identified from a prospective nine-center stroke registry database. Two cohorts were defined: patients diagnosed with AF prior to the stroke event (admission cohort) and patients diagnosed with AF at discharge from hospital (discharge cohort). Any of the following conditions were regarded as nonadherence to guidelines in this study: use of anticoagulant or nonuse of antithrombotics with CHADS2 score=0, nonuse of antithrombotics with CHADS2 score=1, or nonuse of anticoagulant with CHADS2 score > or =2. RESULTS: Overall, 406 patients were enrolled in the admission cohort and 518 in the discharge cohort. The rates of nonadherence before a stroke event and at discharge were 77.8% and 33.3%, respectively. These rates varied widely for both cohorts, with interhospital differences being statistically significant. Multivariable analysis revealed that old age, stroke history, and congestive heart failure were associated with nonadherence before stroke. At discharge, males, coronary heart disease, inappropriate antithrombotic use before stroke, and functional disability at discharge were associated with nonadherence. CONCLUSIONS: This study shows that antithrombotic use in AIS patients with AF might be not optimal before and after stroke in Korea.
