The Effect of Flipped Instruction on Special Education Preservice Teachers\u27 Perceptions
This study analyzes the flipped instruction model used in three special education educator preparation courses to examine which components preservice teachers perceived most contributed to their content knowledge, motivation, and engagement (n=50). Weekly pre-class asynchronous assignments included the use of educational technology tools such as an interactive e-textbook site, Perusall, and online academic activities such as Khan Academy to strengthen their content knowledge. This allowed more time for a student-centered approach during synchronous instruction to incorporate tools such as Nearpod, Pear Deck, Flipgrid and digital badges to strength-en their motivation and engagement. Data were collected through a post-course survey; results indicate that preservice teachers perceived this model was motivating, engaging, and contributed significantly to their content knowledge. They also identified hands-on activities during class as a significant component of their learning. This article discusses the project, limitations, and implications for future flipped instruction research in special education educator preparation programs

The Effect of Thermal Coefficients on Temperature Condition of the Blank in FE Analysis of Warm Hydro mechanical Deep Drawing Process
A challenge to conduct the most accurate FE simulations in Warm Hydromechanical Deep Drawing (WHDD) process is to predict temperature condition of the blank which was held between the heated dies and cooled punch. This is possible by knowing effects of thermal coefficients in the FE analysis of WHDD process and modeling of the heat transfer between the blank and tools accurately. In this study effects of thermal coefficients on the temperature condition of the blank in the FE analysis of WHDD to conduct accurate FE simulations of the process. So, it can be possible to predict deformation behavior of the materials accurately and determining the proper forming conditions in less time and shorting development time. 
Isolated Small Bowel Transplantation in Turkey: A Single Center Experience Running Title: Isolated Small Bowel Transplantation in Turkey
Background SBTx has become a feasible therapeutic option for patients with irreversible intestinal failure. Increase in the number and in the improvement of the patient and graft survival in SBTx has a slow course when compared to other solid organ transplantation. Aim The aim of this study is to analyze 25 isolated SBTx performed since 2003 at a single center. It also aims to compare the patient and graft survivals rate during the early (before 2010) and late (after 2010) period. Materials and Methods Medical charts of 24 patients were analyzed retrospectively. To compare the center’s experience during a twelve year period, the results were divided into two groups (before (n:7) and after 2010 (n:18)). At the appropriate time, data were reported as mean± standard deviation, median, and range. Kaplan Meier method was used for the survival analysis of the graft and the patients. Results Median age of the patients was 39 (min 6 months, max: 56 yr). Six of them were in the pediatric age group. Compared to before 2010, graft survival rates increased from 28.1% to 53.8% in 3 months, from 28.6% to 35.9% in 6 months, and from 14.3% to 29.9% in one year after 2010. At the same period, patient survival rate increased from 57.1% to 72.2% in 3 months, from 28.6% to 38.9% in 6 months, and from 14.3% to 33.3% in one year. In the pediatric age group, patient and graft survival rates were 85.7% in 3 months, 71.4% in 6 months, and 71.4 % in 1 year. Conclusion SBTx is an effective treatment choice for selected patients with intestinal failure. Although patient and graft survival rates were improved after 2010 in our center, it was inferior. Patient and graft survival rates in pediatric SBTx are favourable and promising
ABNORMALNI TEST OPTEREĆENJA GLUKOZOM I BLAGI GESTACIJSKI DIJABETES
Objective. The status of carbohydrate metabolism of pregnant women with positive glucose challenge test (GCT), but normal oral glucose tolerance test (OGTT) and their neonates are not defined clearly. Study Design. Pregnant women with normal GCT (n: 120), with abnormal glucose challenge test (AGCT) but normal OGTT (n: 67) and with gestational diabetes (GDM, n: 67) were included into the study. Insulin sensitivity was evaluated by fasting insulin level, homeostasis model assessment of insulin resistance index (HOMA-IR); quantitative insulin check index (QUICKI) and ISOGTT. Serum insulin and glucose values during OGTT were documented. Perinatal outcome and delivery modalities were compared. Results. Both GDM (31.6±5.9 yrs) and AGCT groups (29.0±4.0 yrs) were older than controls (28.1±4.9 yrs). Body mass index (BMI) was the predominant factor affecting both AGCT and GDM groups (OR: 3.78 and 5.97 respectively). Despite there was no significance between insulin indices; serum glucose and insulin values were similarly different; macrosomic infant and caesarean section rates were higher than controls in both GDM and AGCT groups in favor of gestational diabetics (6.6% vs. 18.9%; p=0.0001 and 20% vs. 27.7% p=0.0001 respectively). Conclusion. Pregnant woman with abnormal glucose challenge test have impaired carbohydrate metabolism as in gestational diabetics with a lesser severe degree.Cilj istraživanja. Stanje metabolizma ugljikohidrata u trudnica s pozitivnim testom probira (glucose challenge test – GCT), a normalnim testom opterećenja glukozom (OGTT) te njihove novorođenčadi, nije jasno definirano. Način istraživanja. U studiju su uključene trudnice s normalnim GCT-om (n: 120), s abnormalnim GCT-om ali normalnim OGTT-om (n:67 te trudnice s gestacijskim dijabetesom (n: 67). Insulinska osjetljivost je vrednovana jutarnjiom vrijednošću insulina, modelom prosudbe homeostaze indeksom rezistencije na inzulin (HOMA-IR), kvantitativnim indeksom provjere insulina (QUICKI) i ISOGTT-om. Vrijednosti serumske glukoze i inzulina su analizirane. Uspoređen je perinatalni ishod i način poroda. Rezultati. Trudnice s GDM (31,6±5,9 godina) i one s AGCT (29,0±4,0 godina) su bile starije dobi od kontrolnih trudnica (28,1±4,9 godina). Indeks tjelesne težine (BMI) je bio presudni čimbenik u skupini s AGCT i GDM (OR: 3,78 odnosno 5,97). Unatoč tome nije bilo značajnosti među inzuilinskim indeksima; serumske vrijednosti glukoze i inzulina su bile slično različite; makrosomna djeca i stopa carskih rezova su u trudnica s AGCT i OGTT bile češće, posebice u trudnica s GDM (6,6% prama 18,9%, p = 0,0001; 20% prama 27,7%, p = 0,0001). Zaključak. Trudnice s abnormalnim testom probira na glukozu (AGCT) imaju poremećaj metabolizma ugljikohidrata kao i trudnice s gestacijskim dijabetesom (GDM), ali u nešto manjoj mjeri
Practical recommendations of the EAU-ESPU guidelines committee for monosymptomatic enuresis-Bedwetting
Background and Aims The objective of this update of the EAU-ESPU guidelines recommendations for nocturnal enuresis was to review the recent published literature of studies, reviews, guidelines regarding the etiology, diagnosis and treatment options of nocturnal enuresis and transform the information into a practical recommendation strategy for the general practitioner, pediatrician, pediatric urologist and urologist. Material and Methods Since 2012 a monthly literature search using Scopus (R) was performed and the relevant literature was reviewed and prospectively registered on the European Urology bedwetting enuresis resource center (). In addition, guideline papers and statements of the European Society for Paediatric Urology (ESPU), the European Association of Urology (EAU), the National Institute for Health and Care Excellence (NICE) and the International Children Continence Society (ICCS) were used to update the knowledge and evidence resulting in this practical recommendation strategy. Recommendations have been discussed and agreed within the working group of the EAU-ESPU guidelines committee members. Results The recommendations focus to place the child and his family in a control position. Pragmatic analysis is made of the bedwetting problem by collecting voiding and drinking habits during the day, measuring nighttime urine production and identification of possible risk factors such as high-volume evening drinking, nighttime overactive bladder, behavioral or psychological problems or sleep disordered breathing. A questionnaire will help to identify those risk factors. Conclusion Motivation of the child is important for success. Continuous involvement of the child and the family in the treatment will improve treatment compliance, success and patient satisfaction
Are there any benefits of using an inlay graft in the treatment of primary hypospadias in children?:A systematic review and metanalysis
INTRODUCTION: Dorsal inlay graft urethroplasty (DIGU) has been described as an effective method for hypospadias repair with the proposed advantage of reducing the risk of complications. We aimed to systematically assess whether DIGU has any additional advantages over standard tubularized incised plate urethroplasty (TIPU) repair in children with primary hypospadias. MATERIALS AND METHODS: This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. The a priori protocol is available at the PROSPERO database (CRD42020168305). A literature search was conducted for relevant publications from 1946 until January 10, 2020 in seven different databases. Randomized controlled trials (RCTs), comparative studies (TIPU vs DIGU) and single arm case series (>20 cases) of DIGU were eligible for inclusion. Secondary hypospadias, two-stage repairs, disorders of sex development, significant curvature of >30°, and a mean or median follow-up of less than 12 months were excluded. DISCUSSION: A total of 499 articles were screened and 14 studies (3 RCTs, 5 non-randomized studies (NRSs), and 6 case series) with a total of 1753 children (distal: 1334 (76%) and proximal: 419 (24%)) were found eligible. Mean follow-up of the studies was between 16 and 77 months. DIGU was found superior to TIPU in decreasing meatal/neourethral stenosis (p = 0.02, 95% CI 0.02-0.78). All other parameters were found comparable including overall complications, fistula and glans dehiscence rates. Success rates were similar among the groups ranging between 48% and 96% for DIGU and 43-96% in the TIPU group. The lack of standardization in the definition of complications and success was the major limitation of this study. CONCLUSIONS: Using an inlay graft during primary hypospadias repair decreases the risk of meatal/neourethral stenosis. However, current evidence does not demonstrate superiority of DIGU over TIPU in terms of treatment success and overall complication rates
The effect of suture materials with different absorption times on isthmocele: a retrospective study
Objectives: With the increasing rate of cesarean operations, the formation of niches and related early and late complications have been observed more frequently. In this study, we examined the effects of using a suture material that can be absorbed faster than conventional sutures on the formation of niches.
Material and methods: This study was designed as a retrospective study and completed with a total of 101 patients. During the cesarean operation, the uterus was closed with Rapide Vicryl® in 49 patients and Vicryl® in 52 patients. The uterine niche was measured with a sonohysterogram 6 months after the operation. The primary outcome of the study was determined as uterine niche formation and the secondary outcome was the post-menstrual spotting (PMS) rate.
Results: Duration of surgery, intraoperative/postoperative blood loss, and hospitalization time were similar between the two groups. Niche formation was significantly lower in the Rapide Vicryl group (22.4%) when compared to the Vicryl group (42.3%) (p = 0.046). Also, PMS was observed significantly lower in the Rapide Vicryl group (16.2% and 52.8% in Rapide Vicryl and Vicryl groups, respectively; p = 0.002).
Conclusions: The formation of niches and associated PMS rates were less with suture materials that were absorbed faster
Comparison of prognostic scores and surgical approaches to treat spinal metastatic tumors: A review of 57 cases
Surgical treatment of metastatic spinal cord compression with or without neural deficit is controversial. Karnofsky and Tokuhashi scores have been proposed for prognosis of spinal metastasis. Here, we conducted a retrospective analysis of Karnofsky and modified Tokuhashi scores in 57 consecutive patients undergoing surgery for secondary spinal metastases to evaluate the value of these scores in aiding decision making for surgery. Comparison of preoperative Karnofsky and modified Tokuhashi scores with the type of the surgical approach for each patient revealed that both scores not only reliably estimate life expectancy, but also objectively improved surgical decisions. When the general status of the patient is poor (i.e., Karnofsky score less than 40% or modified Tokuhashi score of 5 or greater), palliative treatments and radiotherapy, rather than surgery, should be considered
