PURPOSE: Pelvic floor muscles play an important role in female sexual function. Urinary incontinence is one of the complex symptoms of pelvic floor relaxation. The purpose of the present study was to evaluate the effects of behavioral treatment on the sexual life variables and quality of life in stress urinary incontinent women. MATERIALS AND METHODS: Fifty women with clinically and urodynamically proven stress urinary incontinence were randomly selected, and treated with functional electrical stimulation (FES) -Biofeedback. The FES-Biofeedback treatment was performed for 20 min per session, 2 sessions a week, for 6 weeks. The treatment consisted of electrical stimulation (35Hz and 50Hz, simultaneously) for 24 seconds, and the biofeedback, composed of 3 phases of contraction, lasted for 32 seconds. The outcome measures on the sexual life variables and quality of life scales were assessed by the Bristol Female Lower Urinary Tract Symptoms questionnaire and a self-developed questionnaire, based on the Brief index of sexual Functioning for women (BISF-W). RESULTS: The general quality of life scores were significantly improved after 6 weeks of FES-Biofeedback (p<0.05). The quality of orgasms, sexual interest, sexual activity and sexual anxiety were significantly improved after the FES-Biofeedback (p<0.05). Changes in the scores for the degree of satisfaction in those variables also showed statistical significance (p<0.05). CONCLUSIONS: Women with incontinence were dissatisfied with their sexual life due to various symptoms associated with their urinary symptoms or symptoms that result from pelvic floor relaxation. The FES-Biofeedback therapy showed positive effects on improving, not only stress incontinence, but also sexual life variables and the life quality.

Purpose: This study was conducted to develop a unified structural model that defines relationships among the factors that affect happiness in adolescents in South Korea. Methods: This study was performed using the dataset from the 2018 Korean Children and Youth Panel Survey (KCYPS). The study participants were 2590 adolescents recruited through probability proportional to size (PPS) sampling. The data were analyzed using descriptive statistics, Pearson’s correlation coefficient, and structural equation modeling to determine the factors that influence adolescents' happiness. Results: Our proposed structural model demonstrated a fine fitness level. Our proposed structural model was also able to describe happiness for adolescents with 68.2% accuracy. Positive social support, high self-esteem, and low depression were confirmed as key factors that influence happiness among adolescents. Meanwhile, physical symptoms were not shown to influence happiness for adolescents in South Korea. Conclusion We suggest that intervention is required to increase happiness in adolescents. Specifically, there is a need for combinational interventions that help adolescents in South Korea increase their social support and self-esteem while reducing their depression.

PURPOSE: Authors develop a unified structural model that defines multirelationships between systematic factors causing excessive use of smartphones and the corresponding results. METHODS: A survey was conducted with adolescents who live in Seoul, Pusan, Gangneung, Donghae, and Samcheok from February to March 2016. Authors used SPSS, version 22.0, and AMOS, version 22.0, to analyze the survey results at a .05 significance level. To investigate demographic characteristics of the participants and their variations, descriptive analysis was used. The maximum likelihood estimate method was adopted to verify the fitness of the hypothetical model and the hypotheses therein. Authors used χ² statistics, goodness-of-fit index, adjusted goodness-of-fit index, comparative fit index, normed fit index, incremental fit index, root mean square residual, and root mean square error of approximation to verify the fitness of our structural model. RESULTS: (1) The proposed structural model demonstrated a fine fitness level. (2) The proposed structural model could describe the excessive use of a smartphone with 88.6% accuracy. (3) The absence of the family function and relationship between friends, impulsiveness, and low self-esteem were confirmed as key factors that cause an excessive use of smartphones. (4) Furthermore, impulsiveness and low self-esteem are closely related to the absence of family functions and relations between friends by 68.3% and 54.4%, respectively. CONCLUSION: Authors suggest that nursing intervention programs from various angles are required to reduce adolescents' excessive use of smartphones. For example, family communication programs would be helpful for both parents and children. Consultant programs about relationships with friends would also be helpful.

PURPOSE: The aim of this study was to develop a structural model based on Bronfenbrenner's ecology of human development theory, that illustrates relationships of happiness and associated factors among Korean college students. METHODS: Study participants were 357 college students recruited from five universities throughout the convenience sampling. Self-reported data were collected from November, 2018 to January, 2019. The data were analyzed using descriptive statistics, Pearson's correlation coefficients, and a structural equation modeling in order to identify factors associated with college students' happiness. RESULTS: The tested model demonstrated the acceptable model fit compared to the hypothesized model, that explained college students' happiness with 68.7% accuracy. Positive family function, high self esteem and ego-resilience were significant factors associated with happiness for college students. However, positive friend support was not significant in our model. CONCLUSION: Our study findings suggest that both family and individual interventions are required to reduce negative emotions and increase happiness of college students. In particular, multicomponent interventions should include the concepts of self esteem, ego-resilience, and family function in terms of assessment and intervention contents tailored to Korean college students.

Innovative advances in stem cell research have resulted in the development of organoids, which are widely used as in vitro models of human organ development and for disease. The long-term goals of scientists include the generation of high-quality organoids with properties like those of native organs, and to expand their use to a variety of applications such as drug discovery and organoid-based cell therapy. In particular, the combination of human induced pluripotent stem cell (iPSC)-derived organoids with the recently developed genome engineering, biotechnology serve as an attractive platform in precision medicine. This review briefly summarizes the generation of organoids derived mostly from iPSCs without ethical issues, and describes the applications and technological advances of organoids under their differentiation and culture conditions. We also discuss the approaches to improve the organoid models, and how organoids can recapitulate mature organ systems of the human body for regenerative medicine. Finally, the future perspectives and remaining challenges in the field have been discussed to provide a better understanding of the potential applications of organoids.

Balloon sinuplasty (BSP) is a newly developed catheter-based technique for dilating sinus ostia to improve sinus ventilation and drainage. BSP has been in clinical use since 2005, but there has been many debates and criticism between early movers and mainstream doctors. But, recently, many evidences strongly support its safety, efficacy, and growing popularity among patients and physicians. The objective of this clinical review is to present its theoretical background, technical considerations, and treatment outcomes. BSP will be an additional tool for treating sinusitis, either alone or with conventional sinus surgery technique.

Many of early findings regarding intestinal stem cells (ISCs) and their niche in the human intestine have relied on colorectal cancer cell lines and labor-intensive and time-consuming mouse models. However, these models cannot accurately recapitulate the physiologically relevant aspects of human ISCs. In this study, we demonstrate a reliable and robust culture method for 3D expanding intestinal spheroids (InSexp ) mainly comprising ISCs and progenitors, which can be derived from 3D human intestinal organoids (HIOs). We did functional chararcterization of InSexp derived from 3D HIOs, differentiated from human pluripotent stem cells, and optimization culture methods. Our results indicate that InSexp can be rapidly expanded and easily passaged, and show enhanced growth rates via WNT pathway activation. InSexp are capable of exponential cell expansion and cryopreservation. Furthermore, in vitro-matured HIO-derived InSexp proliferate faster than immature HIO-derived InSexp with preservation of the parental HIO characteristics. These findings may facilitate the development of scalable culture systems for the long-term maintenance of human ISCs and provide an alternative platform for studying ISC biology.

In the patient with extensive burn injury, the occult site of infection such as septic arthritis is easy to be overlooked because a painful hip joint may be confused for painful burn wounds around pelvic area. We describe a extensive burned young adult who experienced a septic hip joint with methicillin resistant Staphylococcus aureus bacteremia A 22 year old male who had full thickness burns of whole body (90%) presented with fever, groin pain, and immobility of right hip joint about 3 months after injury. The physical findings, radiographic findings and bone scan were diagnostic for a septic arthritis. Septic arthritis in the extensive burns may be misdiagnosed for painful burn wounds. Hematogenous septic hip arthritis by sustained bacteremia is rare, but clinical examination combined with appropriate laboratory and radiographic studies can lead to prompt diagnosis and treatment.
