PURPOSE: This study aimed to develop a smartphone overdependence prevention program for college students based on the self-determination theory (SDT) and evaluate its effectiveness.METHODS: A non-equivalent control group repeated measures design was used for the study. Participants were 64 university freshmen (experimental group: 29, control group: 35). The developed program consists of eight sessions conducted twice a week. The program was designed to promote autonomy, competence, and relatedness the three elements of the basic psychological needs of self-determination theory. The participants were assessed before the program, immediately after, and 1 and 3 months after the program. Data were collected from April 23 to September 14, 2018 and analyzed by performing a Chi-square test, Fisher's exact test, independent t-test, and repeated measures ANOVA using SPSS/WIN 23.0.RESULTS: This study showed improvement in the basic psychological needs (F=3.90, p =.010) in the experimental group compared to the control group. Specifically, competence (F=2.93, p =.035), relatedness (F=2.89, p =.045), and self-regulatory ability (F=3.11, p =.028) improved significantly.CONCLUSION: Study findings indicate thatthe smartphone overdependence prevention program based on the Self-determination theory could be an effective intervention for improving basic psychological needs and self-regulation ability. Therefore, this program could be an efficient strategy for smartphone overdependence prevention in university students.

Percutaneous pulmonary valve implantation (PPVI) is recognized as a feasible and low risk alternative to surgery to treat dysfunctional right ventricular outflow tract (RVOT) in usually pluri-operated patients. Evolving technology allowed to develop different kind of prosthesis and to go from an initial treatment exclusively of stenotic conduit to an actual approach extended also to wide native RVOT. The Melody transcatheter pulmonary valve (TPV) and the Edwards Sapien valve are nowadays the most commonly implanted prostheses. However, other devices have been developed to treat large RVOT (i.e., the Venus p-valve, the Medtronic Harmony TPV, the Alterra Adaptive Prestent, and the Pulsta valve). Indications for PPVI are the same as for surgical interventions on pulmonary valve, with limits related to the maximum diameter of the available percutaneous prosthesis. Therefore, an accurate preoperative evaluation is of paramount importance to select patients who could benefit from this procedure. The overall periprocedural mortality incidence is around 1.4%, while freedom from RVOT reintervention ranges from 100% at 4 months to 70% at 70 months, according to the different published studies.

Freedom from adverse aortic events (aortic dissection or rupture, reoperation, or sudden death) at 10 years was 97.9%. No significant dilation at the level of the sinuses of Valsalva (0.069 mm/year, p=0.524) or ascending aorta (0.152 mm/year, p=0.124) was observed. Significant dilation occurred at the proximal aortic arch (0.343 mm/year, p=0.006). Subgroup analysis with a multivariable linear mixed model identified initial ascending aortic diameter to be a significant predictor of proximal arch dilation (p=0.032). Receiver operating characteristic curve analysis revealed that the cut-off for the prediction of proximal arch redilation was an initial mid-ascending aortic diameter of 47.0 mm (area under the curve 0.747, 90% confidence interval 0.613–0.881, p=0.023).CONCLUSION: Aortic wrapping could be considered as a safe and long-term therapeutic option. Redilation of the proximal arch should be carefully observed during long-term follow-up.]]>

PURPOSE: With continuous positive airway pressure (CPAP) being the treatment of choice for Obstructive Sleep Apnea (OSA), adherence rates to CPAP are still low without a clear consensus of causes. The Self-Determination Theory (SDT) is a general theory of human motivation that emphasizes the extent to which behaviors are relatively autonomous based on the psychological needs that are critical to supporting the process of internalization and the development of optimal motivation. This study sought to determine whether the implementation of an SDT-based intervention is effective in improving: (1) perceived competence, (2) treatment self-regulation, (3) CPAP treatment adherence, and (4) Apnea–hypopnea index (AHI) of OSA patients. METHODS. Using a true experimental pretest-posttest design, 30 purposively selected participants were randomly allocated to experimental and control groups. The SDT-based intervention included group sessions, individual sessions, and follow up phone calls in three weeks. Written permission to conduct the study was obtained from the Institutional Review Board of the University of the East - Ramon Magsaysay Memorial Medical Center, Inc. (UERMMMCI) and the Lung Center of the Philippines. Participation was voluntary and all participants had the right to refuse or discontinue their participation at any time during the study. Data were analyzed using two way repeated-measures ANOVA, student's T-test, and chi-square. RESULTS AND CONCLUSION: The participants in the experimental group have increased adherence rates from Time 1 (60%) to Time 2 (92.9%) and Time 3 (85.7%). Although, when compared to the control group, no significant difference was noted across the different periods of measurement (p=0.70810, p=0870, p=0.2403). There were higher proportions of patients who eventually became adherent in the experimental group compared to the control group immediately after and 5 weeks after the intervention (p=0.0001). The experimental group had significantly better improvement in AHI compared to the control group immediately after (p=0.0152) and 5 weeks after the intervention (p=0.0022). Considering the importance of CPAP adherence in effectively treating OSA, measures to improve adherence such as SDT-based intervention could be usefully incorporated into OSA patients' treatment plans.

PURPOSE: Although laparoscopic surgery had been performed in clinical practice for over 30 years, there has not been much improvement on instruments. Several articulating laparoscopic instruments have been developed including the robotic system. A new multi-degree of freedom (DOF) articulating laparoscopic device has been developed. We compared the ability to perform challenging sutures between the new device and the robotic system.METHODS: Five experienced surgeons with over 100 laparoscopic surgery cases performed the suture task with both instruments. Everyone was new at articulating instruments including a robotic system. The suturing task consisted of two vertical sutures, downward and upward vertical direction. The duration of needle grabbing, first surgical tie, square tie, and the final reverse tie was measured.RESULTS: When doing the downward suture, the median time to complete the suture was 127 vs. 136 seconds for ArtiSential® and the robot, respectively (p=0.754). Other measurements such as needle grabbing, first tie, second tie and final knot did not show any significant difference between the two instruments. Upward suture also did not show a significant difference. The total completion time was 127 vs. 112 seconds for for ArtiSential® and the robot, respectively (p=0.675). Time taken in each interval did not show any significant difference.CONCLUSION: Both instruments performed the suturing tasks with no difference in duration. ArtiSential® can be mixed up with usual instruments. Surgeons can choose any device, but when articulation is needed, ArtiSential® could be an alternative choice to the robotic system.

BACKGROUND: This study investigated the current status of communication about death and confidence levels concerning death-related issues among Korean adults.METHODS: A survey was conducted to ascertain the frequency of death related communication, factors promoting and impeding such communication, and confidence levels concerning death-related issues. Data of 112 participants who completed the survey were analyzed using descriptive statistics, a chi square test, and multiple logistic regression.RESULTS: More than half of the participants (52.7%–84.0%) appeared to have infrequent (never/at least one) conversations about death or death-related issues. Owing to socio-cultural aspects, death-related communication was considered a taboo or an unpleasant topic of conversation. Additionally, indifference toward death inhibited people from communicating; however, personal experiences of death or morbidity and favorable social contexts promoted communication. Overall, the confidence levels concerning death-related issues was low. Only 17.9%–32.2% of the participants were confident/very confident about their preferences concerning death-related issues. The more people talked about death, the more likely they were to develop a confident attitude toward death-related issues (odds ratio, 3.45; 95% confidence interval, 1.37–8.69).CONCLUSION: This study confirmed that communication about death is being withheld among Koreans, and this could possibly lower their level of confidence regarding death-related issues. To achieve death with dignity, a ‘death culture’ needs to be promoted alongside legislation and infrastructure.

Focal cortical dysplasia (FCD) is the major cause of intractable focal epilepsy in childhood leading to epilepsy surgery. The overall seizure freedom after surgery ranges between 50–75% at 2 years after surgery and the long-term seizure freedom remain relatively stable. Seizure outcome after surgery depends on a various factors such as pathologic etiologies, extent of lesion, and types of surgery. Therefore, seizure outcome after surgery for FCD should be analyzed carefully considering cohorts' characteristics. Studies of pediatric epilepsy surgery emphasize the early surgical intervention for a better cognition. Early surgical intervention and cessation of seizure activity are important for children with intractable epilepsy. However, there are limited data on the cognitive outcome after surgery in pediatric FCD, requiring further investigation. This paper reviews the seizure and cognitive outcomes of epilepsy surgery for FCD in children. Several prognostic factors influencing seizure outcome after surgery will be discussed in detail.

PURPOSE: To determine associations of traumatic events and post-traumatic stress disorder (PTSD) with sexual autonomy and identify factors influencing sexual autonomy among female university students of North Korean defectors. METHODS: A cross-sectional, descriptive study was performed with a total of 103 female students who completed a structured online self-report survey from January 7 to March 31, 2018. This study was conducted using questionnaires on interpersonal trauma scale, the Traumatic Scale for North Korean Refugees (TSNKR), and sexual autonomy measurement for college students. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple linear regression with SPSS WIN 23.0 program. RESULTS: Traumatic events, PTSD, and sexual autonomy scores were 3.96±3.07, 31.47±10.75, and 52.66±6.89, respectively. PTSD was positively correlated with traumatic events (r=.22, p=.030). Sexual autonomy was inversely correlated with PTSD (r=−.25, p=.010). Contraceptive use, PTSD, and voluntary sexual debut explained 26% of sexual autonomy of participants. CONCLUSION: To improve sexual autonomy of young women from North Korea, reproductive intervention programs including contraception, sexual assertiveness training, and psychoeducation to reduce PTSD need to be developed and implemented.

BACKGROUND: Optimal graft selection for coronary artery bypass grafting (CABG) in patients with severe left ventricular (LV) dysfunction remains debatable. We report an analysis of our experiences of isolated CABG in patients with severe LV dysfunction and the impact of graft strategy on long-term outcomes. METHODS: We analyzed 209 patients with severe LV dysfunction (ejection fraction [EF] <30%) who underwent primary isolated CABG. Of these, 169 were revascularized with a bilateral internal thoracic arterial (ITA) graft (BITA group) and 40 were revascularized with a single ITA graft (SITA group). The mean follow-up duration was 22±32 months. RESULTS: There were 18 early deaths (8.6%). Overall survival at 5 years was 66.7%. The rate of freedom from cardiac-related death at 5 years was 74.1%, and was significantly higher in patients who underwent off-pump CABG (p=0.005) and in the BITA group (p=0.023). Multivariate analysis demonstrated that old age (hazard ratio [HR], 2.548; 95% confidence interval [CI], 1.134–5.762; p=0.024), off-pump CABG (HR, 0.245; 95% CI, 0.090–0.661; p=0.006), and BITA grafts (HR, 0.333; 95% CI, 0.146–0.757; p=0.009) were correlated with cardiac mortality. CONCLUSION: CABG in patients with severe LV dysfunction (EF < 30%) showed reasonable long-term outcomes. The rate of freedom from cardiac-related death was significantly higher in patients who underwent off-pump CABG and in the BITA group. Off-pump BITA grafting strategies can be accepted as a viable primary option in patients with severe LV dysfunction if performed by an experienced surgeon.

BACKGROUND: Although aortic valve repair can reduce prosthesis-related complications, rheumatic aortic regurgitation (AR) caused by leaflet restriction is a significant risk factor for recurrent AR. In this study, we evaluated the long-term results of the leaflet extension technique for rheumatic AR. METHODS: Between 1995 and 2016, 33 patients underwent aortic valve repair using the leaflet extension technique with autologous pericardium for rheumatic pure AR. Twenty patients had severe AR and 9 had combined moderate or greater mitral regurgitation. Their mean age was 32.2±13.9 years. The mean follow-up duration was 18.3±5.8 years. RESULTS: There were no cases of operative mortality, but postoperative complications occurred in 5 patients. Overall survival at 10 and 20 years was 93.5% and 87.1%, respectively. There were no thromboembolic cerebrovascular events, but 4 late deaths occurred, as well as a bleeding event in 1 patient who was taking warfarin. Twelve patients underwent aortic valve reoperation. The mean interval to reoperation was 13.1±6.1 years. Freedom from reoperation at 10 and 20 years was 96.7% and 66.6%, respectively. CONCLUSION: The long-term results of the leaflet extension technique showed acceptable durability and a low incidence of thromboembolic events and bleeding. The leaflet extension technique may be a good option for young patients with rheumatic AR.
