Objectives: This study aimed to determine the prevalence and correlates of sexual intercourse among junior secondary and high school students in Indonesia from the 2015 Global School-based Health Survey (GSHS). Methods: The survey was conducted among 11 110 students from 75 schools in Indonesia using a self-administered questionnaire. Univariate and multivariate analyses were conducted to explore associations between sexual intercourse and socio-demographic variables, substance use, mental distress, and protective factors. Results: Overall, 5.3% of students reported having ever had sex (6.9% of boys and 3.8% of girls). Of students who engaged in sexual intercourse, 72.7% of boys and 90.3% of girls had an early sexual debut (before reaching the age of 15) and around 60% had multiple sex partners. Sexual intercourse was associated with gender, school grade, smoking, alcohol consumption, drug use, suicidal ideation, truancy, peer support, and parental supervision. Conclusions: These findings indicate a pressing need to develop more comprehensive sexual health education in the national curriculum. An effective strategy should also address other risky behaviours.

Objective: To compare dentoalveolar and skeletal changes produced by the pendulum appliance (PA) and the distal screw appliance (DS) in Class II patients. Methods: Forty-three patients (19 men, 24 women) with Class II malocclusion were retrospectively selected for the study. Twenty-four patients (mean age, $12.2{\pm}1.5years$) were treated with the PA, and 19 patients (mean age, $11.3{\pm}1.9years$) were treated with the DS. The mean distalization time was 7 months for the PA group and 9 months for the DS group. Lateral cephalograms were obtained at T1, before treatment, and at T2, the end of distalization. A Mann-Whitney U test was used for statistical comparisons of the two groups between T1 and T2. Results: PA and DS were equally effective in distalizing maxillary molars (4.7 mm and 4.2 mm, respectively) between T1 and T2; however, the maxillary first molars showed less distal tipping in the DS group than in the PA group ($3.2^{\circ}$ vs. $9.0^{\circ}$, respectively). Moreover, significant premolar anchorage loss (2.7 mm) and incisor proclination ($5.0^{\circ}$) were noted in the PA group, whereas premolar distal movement (1.9 mm) and no significant changes at the incisor ($0.1^{\circ}$) were observed in the DS group. No significant sagittal or vertical skeletal changes were detected between the two groups during the distalization phase. Conclusions: PA and DS seem to be equally effective in distalizing maxillary molars; however, greater distal molar tipping and premolar anchorage loss can be expected using PA.

The endocrinology of type 2 diabetes (T2D) and its predisposing factors have been studied extensively while its skeletal effects have received negligible research despite this being a global disease. The cellular and molecular association between proximal humeral fractures and T2D has not been fully elucidated. We aimed to study bone cell quantities and immunolabel osteogenic and antiosteogenic cytokines. The study used 12-week-old rats (23 males) consisting of 8 Sprague Dawley (SD) and 15 Zucker Diabetic Sprague Dawley (ZDSD). Weekly mass measurements were taken while fasting blood glucose levels were recorded every 2 weeks with oral glucose tolerance tests conducted once every 4 weeks. Upon termination at the age of 28 weeks, humeri were fixed in 10% buffered formalin, prior to decalcification in ethylenediaminetetraacetic acid. The bone samples were then processed in ascending grades of alcohol using an automatic processor before embedding in paraffin wax. Sections were cut at 5 ㎛ thickness in a series for Haematoxylin and Eosin stain, and immunohistochemistry was performed with the anti-tartrate-resistant acid phosphatase (TRAP), anti-alkaline phosphatase (ALP), anti-bone morphogenetic protein 3 (BMP3), anti-transforming growth factor beta 1 (TGFβ1), anti-aged glycation end product (AGE) antibodies in the sequence. ZDSD rats had more adipocytes, BMP3 and AGEs expression with higher numbers of TRAP positive osteocytes and fewer ALP cells although no differences were found in TGFβ1 immunopositivity. We also found that T2D increases the number of AGEs immuno-positive cells, as well as its extracellular expression, thus providing a conducive environment for the interaction of the osteogenic cytokine and its antagonist to suppress osteoblastogenesis. ZDSD groups had higher adipocyte numbers therefore increased marrow adiposity in T2D.

Objectives: The purpose of this study was to assess the incidence of delivery and puerperium complications in South Korea and analyze the correlations between the patient's characteristics and delivery and complications before and after 10 years. Methods: This study used the data from an Korean National Hospital Discharge In-depth Injury Survey. Cases of which the principal diagnosis and second diagnoses were disease classification ICD code O00-O99(Pregnancy, childbirth and the puerperium) were defined as the study subjects, and the first study group was divided as the year of discharge from 2005 to 2007, and the second study group from 2015 to 2017. Results: The number of patients discharged whose principal diagnosis or second diagnoses was O00-O99 was 21,598(Weighted 423,306) from 2005 to 2007 and 19,028(Weighted 364,384) from 2015 to 2017, which decreased by 13.9% compared to 10 years ago. The average age of discharged patients increased by about 2 years and was statistically significant (p<.0001). Factors associating spontaneous delivery, caesarean section and puerperium complication were hospitalization route, bed size, maternal age, length of hospital stay, and the year of discharge. Conclusion: Based on the results of this study, health and education policies and economic support for medical care for high-risk pregnancy and delivery management would be necessary continuously. In addition, policies to strengthen the medical system for high-risk pregnancy management in non-metropolitan areas with high fertility rates would also be needed.

Background: We prospectively compared the response to blind and ultrasound-guided glenohumeral injection of corticosteroids for treatment of shoulder stiffness. Methods: A total of 77 patients with shoulder stiffness between April 2008 and March 2012 were recruited. Patients were randomized to receive either a blind (group 1, n=39) or ultrasound-guided (group 2, n=38) glenohumeral injection of 40 mg triamcinolone. The clinical outcomes and shoulder range of motion (ROM) before injection, at 3, 6, and 12 months after injection and at the last follow-up were assessed. The same rehabilitation program was applied in both groups during the follow-up period. Results: There was no significant difference in demographic data on age, sex, ROM, and symptom duration before injection between groups (p>0.05). There were no significant differences in ROM including forward flexion, external rotation at the side, external rotation at $90^{\circ}$ abduction, and internal rotation, visual analogue scale for pain and functional outcomes including American Shoulder and Elbow Surgeons score, Simple Shoulder test between the two groups at any time point (p>0.05). Conclusions: Based on the current data, the result of ultrasound-guided glenohumeral injection was not superior to that of blind injection in the treatment of shoulder stiffness. We suggest that ultrasound-guided glenohumeral injection could be performed according to the patient's compliance and the surgeon's preference. Once familiar with the non-imaging-guided glenohumeral injection, it is an efficient and reliable method for the experienced surgeon. Ultrasound could be performed according to the surgeon's preference.

Background Reduction mammoplasty or mastopexy is performed as an additional balancing procedure in patients with large or ptotic breasts who undergo breast-conserving surgery (BCS). Radiation therapy on breasts that have undergone surgery may result in changes in the volume. This study presents a comparative analysis of patients who received post-BCS balancing procedures to determine whether volume changes were larger in breasts that received radiation therapy than on the contralateral side. Methods Thirty-six participants were selected among patients who received BCS using the inverted-T scar technique between September 2012 and July 2017, were followed up for 2 or more years, and had pre-radiation therapy computed tomography images and post-radiation therapy images taken between 12 and 18 months after completion. The average age of the participants was 53.5 years, their average body mass index was 26.62 kg/㎡. Results The pre- and post-radiation therapy volumes of the breasts receiving BCS were 666.08±147.48 mL and 649.33±130.35 mL, respectively. In the contralateral breasts, the volume before radiation therapy was 637.69±145.72 mL, which decreased to 628.14±166.41 mL after therapy. The volume ratio of the affected to the contralateral breasts was 1.05±0.10 before radiation therapy and 1.06±0.12 after radiation therapy. Conclusions The ratio of the volume between the two breasts immediately after surgery and at roughly 18 months postoperatively was not significantly different (P=0.98). For these reasons, we recommend a simultaneous single-stage balancing procedure as a reasonable option for patients who require radiation therapy after BCS without concerns regarding volume change.

Background: There have been few studies in Turkey on the incidence of childhood cancers. A mother's knowledge about signs and symptoms of cancer is important for early diagnosis, effective treatment, and improvement of life expectancy. This study was conducted with a group of mothers of children, aged 0-13, at a Family Health Center (FHC) in Turkey's Eastern Black Sea Region, to analyze their knowledge about cancer symptoms in childhood. Materials and Methods: The study group of this descriptive/cross-sectional research comprised 2,061 mothers, ages 19-49, at an FHC in the Eastern Black Sea Region in February 1, 2011 - June 1, 2011. Before the study, permission was obtained from the local ethics board and the institutions concerned. A value of p<0.05 was accepted as statistically significant. Results: Of the mothers, 34.9% were between the ages of 40-47, 40.5% had three children, 73.8% had no experience with children with cancer, 45.9% said they learned about cancer on television, 39.7% stated that the primary reason for childhood cancer was the mother's smoking during pregnancy, 68.8% said that early diagnosis would save a child, and 98% wanted to learn about childhood cancer. Conclusion: It was determined that the mothers' knowledge of cancer was deficient.

Osteoarthritis has been considered a disease of the elderly because it is uncommon before the age of 40 years and is seen in approximately 80% of United States citizens older than 65 years. general population on kuri city in korea revealed that prevalence of knee osteoarthritis is 10.2%, increasing with age. High level of physical activity in men and age, post-menopause and obesity in women can be risk factor. Osteoarthritis is no evidence that a acquired process initiated much earlier in life through mechanical, metabolic, genetic, or other origins. A high tibial osteotomy alters static lower extremity alignment thereby decreasing medial compartment loading. As well, conservative treatment strategies, such as knee braces and valgus heel wedges, affect lover limb mechanics and attempt to reduce medial compartment loading. It was hypothesized that valgus heel wedges and modified orthoses would shift the center of pressure laterally on the foot during level walking, reducing the moment arm of the adduction moment in the frontal plane, thereby resulting in a decrease in the knee adduction moment. In the 1980s, the effect of wearing a laterally wedged insole on osteoarthritic patients with a varus deformity of the knee was firsted, and since then, kinematic and kinetic analyses concerning this condition have mainly focused on a static standing position. Since the early 1990s, the beneficial effect of wearing a laterally wedged insole to treat osteoarthritis of the knee has also been reported in dynamic conditions, but these studies did not answer the question of the kinematic and kinetic mechanisms that resulted in the reduced symptoms in patents with knee osteoarthritis. therefore, the effect of wearing laterally wedged insole has not been sufficiently studied.

The authors examined for risk factors for suicide among psychiatric patients who had committed suicide through the analysis of demographic, clinical and psychological characteristics of the patients. The total number of suicides committed during social adjustment period was 9. Male and female ratio was 5:4 and the highest incidence occurred in the age group of 21-29 years. Of the 9 cases, schizophrenia accounted for two-third of the suicides. Among the committed suicides, 4 were in hospitalization and rest were postdischarge state. We found that 4 of 5(80%) suicides occurred in the first year after discharge, and that three fifth(60%) occurred within three months of discharge. In this result, most of suicides occurred immediately or soon after discharge and some during inpatient care. The major precipitating factors the patients showed before committing suicide were realistic and psychological problems. Consquently, they become dejected, experience feelings of hopelessness, go on to a depressed mood, and, in that case, have suicidal ideas that are eventually acted on. We believe that the ability to recognize risk factors for suicide and develop appropriate interventions is key to suicide prevention.
