    A multi-institutional analysis of sequential versus 'sandwich' adjuvant chemotherapy and radiotherapy for stage IIIC endometrial carcinoma
    (2019) Onal, Cem; Sari, Sezin Yuce; Yildirim, Berna Akkus; Yavas, Guler; Gultekin, Melis; Guler, Ozan Cem; Akyurek, Serap; Yildiz, Ferah; 0000-0002-2742-9021; 30887753; D-5195-2014
    Objective: To analyze the outcomes of sequential or sandwich chemotherapy (ChT) and radiotherapy (RT) in patients with node-positive endometrial cancer (EC). Methods: Data from 4 centers were collected retrospectively for 179 patients with stage IIIC EC treated with postoperative RT and ChT (paclitaxel and carboplatin). Patients were either treated with 6 cycles of ChT followed by RT (sequential arm; 96 patients) or with 3 cycles of ChT, RT, and an additional 3 cycles of ChT (sandwich arm; 83 patients). Prognostic factors affecting overall survival (OS) and progression-free survival (PFS) were analyzed. Results: The 5-year OS and PFS rates were 64% and 59%, respectively, with a median followup of 41 months (range, 5-167 months). The 5-year OS rates were significantly higher in the sandwich than sequential arms (74% vs. 56%; p=0.03) and the difference for 5-year PFS rates was nearly significant (65% vs. 54%; p=0.05). In univariate analysis, treatment strategy, age, International Federation of Gynecology and Obstetrics (FIGO) stage, pathology, rate of myometrial invasion, and grade were prognostic factors for OS and PFS. In multivariate analysis, non-endometrioid histology, advanced FIGO stage, and adjuvant sequential ChT and RT were negative predictors for OS, whereas only non-endometrioid histology was a prognostic factor for PFS. Conclusion: Postoperative adjuvant ChT and RT for stage IIIC EC patients, either given sequentially or sandwiched, offers excellent clinical efficacy and acceptably low toxicity. Our data support the superiority of the sandwich regimen compared to the sequential strategy in stage IIIC EC patients for OS.

    The Effect of the Cause of Delivery on Neonatal Outcomes in Early Preterm Deliveries
    (2019) Baran, Safak Yilmaz; Torer, Birgin; Kalayci, Hakan; Durdag, Gulsen Dogan; 0000-0001-5874-7324; 0000-0002-5505-8707
    The aim of this study was to evaluate the effect of causes of delivery on short-term neonatal morbidities and mortality in EPD (< 34 gestational weeks). We retrospectively analysed the deliveries occurring between 23 + 0 and 33 + 6th gestational weeks at our tertiary center during 2014-2018. A total of 290 deliveries were evaluated, and 369 newborns [singletons (56.4%), twins (36.6%) and triplets (7.1%)] were included in the study. The causes of deliveries were defined as spontaneously preterm birth (n = 107, 29%), preterm premature rupture of membranes (PPROM) (n = 131, 35.5%) or iatrogenic preterm birth (n = 131, 35.5%). The rate of neonatal respiratory distress syndrome (RDS), patent ductus arteriosus, bronchopulmonary dysplasia (BPD), intraventricular haemorrhagia (IVH), necrotising enterocolitis, retinopathy of prematurity, neonatal resuscitation, sepsis and death were similar between groups. However; neonatal RDS, BPD, IVH and sepsis were found to be higher in cases with chorioamnionitis, which could be considered as subcategory of PPROM. Preterm deliveries have an adverse effect on perinatal outcomes. Also, such causes of labor might be related to varied neonatal morbidities. However, splitting to early preterm deliveries into subgroups, according to cause of delivery, did not provide further information to predict such complications except chorioamnionitis.

    Effectiveness of continuous versus pulsed short-wave diathermy in the management of knee osteoarthritis: A randomized pilot study
    (2019) Ozen, Selin; Doganci, Ekin B.; Ozyuvali, Ayla; Yalcin, Ayse Peyman; 31814942
    Background: Short-wave diathermy (SWD) is an electrotherapeutic modality used in the conservative treatment of knee osteoarthritis (KOA). Electromagnetic radiation delivered in continuous (cSWD) or pulse (pSWD) mode provides a deep heating effect on tissues. There is no consensus on outcomes of treatment with cSWD versus pSWD in KOA. The aim of this study was to compare the effects of cSWD versus pSWD on pain, functionality and walking distance in KOA. Methods: 34 female patients aged 49-65 with KOA were randomized into two groups. A total of 27 patients completed the study. One group (n=11) was treated with cSWD, the other (n=16) with pSWD for three weeks. Patients were assessed before, after and at one month post therapy. Outcome measures included visual analogue scale (VAS) for knee pain, Western Ontario and Mcmaster University Osteoarthritis Index (WOMAC) and a six-minute walking test (6MWT). Results: Based on the minimal clinically important improvement (MCII), there was a reduction in VAS and WOMAC scores in both cSWD and pSWD groups post treatment (-37.3mm, 31.2mm respectively for VAS and 26%, 23% respectively for WOMAC) and at one month post treatment. There was no difference in pre and post treatment VAS for pain, WOMAC or 6MWT scores between the two groups. There was a small post treatment effect size on between- group 6MWT scores (Cohen's d: 0.238). Conclusion: Both treatment options appear to be efficacious in reducing pain and improving functionality in KOA. There was no between-group difference. A larger study must be conducted to consolidate these findings.
