Impact of economic problems on depression in single mothers: A comparative study with married women.

OBJECTIVE: The purpose of this study was to investigate the risk factors that influence depression among single mothers. METHODS: Participants were 195 single mothers and 357 married mothers living in an urban community in South Korea. All subjects completed self-report questionnaires that included the following self-rating scales: the Global Assessment of Recent Stress, the Center for Epidemiologic Studies-Depression scale, and the Korean version of the Alcohol Use Disorder Identification Test. Multiple logistic regression analysis was performed to examine independent factors affecting single mothers' depression. RESULTS: The prevalence of depression differed notably between the single mothers and the control group, at 33% and 8%, respectively. In the single mothers, young age, low income, residential instability, high stress, and high alcohol-related problems were determined to be associated with depression. Furthermore, after adjusting for covariates, living in rental housing (OR = 11.46, 95% CI 1.72-76.46) was found to be an independent risk factor of depression in the single mothers, while stress (OR = 1.16, 95% CI 1.09-1.24) was found to have this effect on the married mothers. CONCLUSIONS: Practical services concerning economic stability and parenting support should be provided for single mothers to reduce depression among this demographic.

Psychological and genetic risk factors associated with suicidal behavior in Korean patients with mood disorders.

INTRODUCTION: To prevent suicide, a nationwide important issue in Korea, understanding its etiology is essential. This study aimed to delineate the risk factors for suicidal behavior in mood disorder patients in Korea. METHODS: 216 patients with mood disorders were recruited. We measured suicidal ideation (SI) and suicide attempt (SA) history and the association of six gene polymorphisms with SB: COMT (rs4680), HTR1A (rs6295), TPH1 (rs1800532), BDNF (rs6265), SLC1A3 (rs2269272), and SLC1A2 (rs4755404). RESULTS: Patients in the high-SI and SA groups reported more severe depressive, hopelessness, and anxiety symptoms and lower resilience and used less social support-seeking coping than those in the non-significant SI and non-SA groups. Multivariate logistic analysis revealed that depressive disorder, depressive symptoms, poor social support, and less social support-seeking coping were significant independent predictors of suicidal ideation. After adjustment for covariates, age, alcohol consumption, and the rs4680 AA genotype in the COMT gene were associated with suicide attempt. LIMITATIONS: The modest sample size and a relatively few candidate genes are limitations of the study. In addition, there is no normal control group and the retrospective evaluation of SA limits the interpretation of the causal relationship with factors affecting SA. CONCLUSIONS: Suicidal behavior in Korean patients with mood disorders may be associated with younger age, alcohol consumption, depressive symptoms, poor social support, less social support-seeking coping, and the COMT rs4680 Met/Met genotype.

Mental health among single and partnered parents in South Korea.

OBJECTIVE: This study compares the mental health of single parents relative to partnered parents and assesses the contribution of the social and demographic factors to this difference, examining the gender difference in it. METHODS: We analyzed 12,024 single and partnered subjects, aged 30-59 years, living with children, aged 0-19 years, drawn from the 4th, 5th, and 6th Korea National Health and Nutrition Examination Survey (KNHANES) dataset in South Korea conducted from 2007-2013. Mental health was evaluated by self-reported questionnaires including depressive mood for recent two weeks, presence of suicidal ideation, and the Korean version of the Alcohol Use Disorder Identification Test. Covariates included age, physical illness, socioeconomic status (family income, recipient of national basic livelihood guarantees, educational level, house ownership, job, and residential area), family structure, and support (co-residence of another adult). Multiple logistic regression was carried out and the explained fractions of each covariate was calculated. RESULTS: Single parents had significantly poorer mental health than their partnered counterparts, with odds ratio (OR) of 2.02 (95% confidence interval (CI) 1.56-2.63) for depressive symptoms, 1.69 (95% CI 1.27-2.25) for suicidal ideation, and 1.74 (95% CI 1.38-2.20) for any of the three mental health statuses (suspicious depression, suicidal ideation, and alcohol dependence) after controlling for the covariates. The odds of depressive symptoms (OR = 3.13, 95% CI 2.50-3.93) and suicidal ideation (OR = 2.50, 95% CI 1.97-3.17) among both single fathers and mothers were higher than partnered parents. However, the odds of alcohol dependence were 3.6 times higher among single mothers than partnered mothers (OR = 3.58, 95% CI 1.81-7.08) and were 1.4 times greater among single fathers than partnered fathers (OR = 1.35, 95% CI 0.81-2.25). Socio-economic status explained more than 50% (except for substance use disorders) of the poorer mental health in single parents. These results were more remarkable for single fathers than for single mothers except for alcohol dependence. However, physical illness, family structure, and support made only minor contributions to single parents' mental health. CONCLUSIONS: This study demonstrates that single parents have poorer mental health than partnered parents. Although lower SES is an important factor explaining poorer mental health in single parents, there are other factors we cannot explain about their poor mental health. Therefore, we should pay proper regard to identifying other factors affecting mental health and to establishing policies to support single parents.

Social Behavioral Problems and the Health-Related Quality of Life in Children and Adolescents with Epilepsy.

OBJECTIVE: The purpose of this study was to investigate the impact of specific behavioral problems on the health-related quality of life (HRQOL) in children and adolescents with epilepsy. METHODS: Children and adolescents with epilepsy (n=92; age range=6-17 years) and their mothers completed questionnaires about behavioral problems, HRQOL, socio-demographics, and epilepsy-related variables. To determine significant predictor variables of the HRQOL, the stepwise regression analyses and partial correlations were performed to adjust for other behavioral problems and covariates. RESULTS: The analyses revealed that an increase in social behavioral problems and delinquent behavior was associated with a decrease in the HRQOL. Lower levels of maternal education and the number of antiepileptic drugs were also associated with a decline in the HRQOL; the HRQOL and social behavioral problems remained significantly correlated after adjusting for maternal education level, number of antiepileptic drugs, and non-social behavioral problems. CONCLUSION: Parents and practitioners should provide intervention if behavioral problems, particularly social behavioral problems, are observed in children or adolescents with epilepsy.

Reduced birth weight, cleft palate and preputial abnormalities in a cloned dog.

The aim of the present study was to report a novel developmental abnormality in a cloned dog. A fibroblast cell line was established from an 8-year-old male German shepherd dog. In vivo matured oocytes were retrieved from a large breed dog, and the nucleus was removed from each oocyte. A donor cell was injected into an enucleated oocyte, and the oocyte-cell couplet was fused electrically. After chemical activation, the resulting embryos were transferred into a naturally estrus-synchronized recipient dog, and two cloned pups were delivered by Cesarean section 60 days later. One cloned pup (Clone 1) was healthy, but the other (Clone 2) had a birth weight of only 320 g and cleft palate, failure of preputial closure at the ventral distal part, and persistent penile frenulum. Clone 2 was raised by stomach feeding until Day 40 after birth, where palatoplasty was performed. The abnormalities in external genitalia in Clone 2 resulted in persistent penile extrusion that was surgically corrected. This complex developmental abnormality has not been reported in dogs previously.

A Study on Correlation between Anxiety Symptoms and Suicidal Ideation.

OBJECTIVE: In South Korea, the number of deaths from suicide has increased in the last two decades, and suicide has become both a social and political problem. In this study, after controlling the variables influencing suicidal ideation, it was expected that it would be determined if anxiety symptoms are independently related to suicidal ideation. METHODS: Data were obtained from 327 psychiatric outpatients accomplished a self-reported questionnaire that included sociodemographic characteristics and clinical variables as well as self-rating scales for measuring the severity of one's anxiety, depression, and suicidal ideation. Logistic-regression analyses were used to determine the correlation between anxiety symptoms and significant suicidal ideation, adjusting for covariates. RESULTS: The patients with significant suicidal ideation were shown to be less educated, unemployed, never married, divorced, or separated by death, or living alone, and were shown to have a lower income, a drinking habit, a higher number of past suicide attempts, and more family members who committed suicide, than the patients without significant suicidal ideation. After adjusting the covariates influencing significant suicidal ideation, anxiety symptoms were associated with significant suicidal ideation. However, after adjusting for depressive symptoms, only the trait anxiety was associated with significant suicidal ideation. CONCLUSION: These findings suggest that anxiety symptoms are an independent risk factor for suicidal ideation. Clinicians may thus use anxiety symptoms for the screening examination when evaluating suicidal ideation and risk, and will have to actively evaluate and treat the anxiety symptoms of patients with suicidal tendencies.

A Gartner duct cyst of the vagina causing dysuria and dyschezia in a Yorkshire terrier.

A 5 year-old, intact female Yorkshire terrier was referred for dysuria and dyschezia. The radiographic and ultrasound examination showed a round shaped mass caudal to the urinary bladder that contained anechoic fluid within the thin walls. During surgery, the cyst was noted to be attached to the outer wall of the vagina, not connected to the vaginal lumen. Cystic fluid was removed and the cystic wall was resected. Then the remaining cystic wall was omentalized to prevent a recurrence. Histological examination confirmed that the cyst was of Wolffian duct origin. In this case, a large Gartner duct cyst causing urological problems was diagnosed and removed by surgical resection.
