AbstractOestradiol, an important hormone in follicular development and endometrial receptivity, is closely related to clinical outcomes of fresh in vitro fertilization-embryo transfer (IVF-ET) cycles. A supraphysiologic E2 level is inevitable during controlled ovarian hyper-stimulation (COH), and its effect on the outcome of IVF-ET is controversial. The aim of this retrospective study is to evaluate the association between elevated serum oestradiol (E2) levels on the day of human chorionic gonadotrophin (hCG) administration and neonatal birthweight after IVF-ET cycles. The data of 3659 infertile patients with fresh IVF-ET cycles were analysed retrospectively between August 2009 and February 2017 in First Hospital of Zhengzhou University. Patients were categorized by serum E2 levels on the day of hCG administration into six groups: group 1 (serum E2 levels ≤ 1000 pg/mL, n = 230), group 2 (serum E2 levels between 1001 and 2000 pg/mL, n = 524), group 3 (serum E2 levels between 2001 and 3000 pg/mL, n = 783), group 4 (serum E2 levels between 3001 and 4000 pg/mL, n = 721), group 5 (serum E2 levels between 4001 and 5000 pg/mL, n = 548 ), and group 6 (serum E2 levels > 5000 pg/mL, n = 852). Univariate linear regression was used to evaluate the independent correlation between each factor and outcome index. Multiple logistic regression was used to adjust for confounding factors. The LBW rates were as follows: 3.0% (group 1), 2.9% (group 2), 1.9% (group 3), 2.9% (group 4), 2.9% (group 5), and 2.0% (group 6) (P = 0.629), respectively. There were no statistically significant differences in the incidences of neonatal LBW among the six groups. We did not detect an association between peak serum E2 level during ovarian stimulation and neonatal birthweight after IVF-ET. The results of this retrospective cohort study showed that serum E2 peak levels during ovarian stimulation were not associated with birth weight during IVF cycles. In addition, no association was found between higher E2 levels and increased LBW risk. Our observations suggest that the hyper-oestrogenic milieu during COS does not seem to have adverse effects on the birthweight of offspring after IVF. Although this study provides some reference, the obstetric-related factors were not included due to historical reasons. The impact of the high estrogen environment during COS on the birth weight of IVF offspring still needs future research.

The properties of fibrinogen and fibrin, the levels of fibrincpeptide A (FPA) and fibrin(ogen) degradation products (FDP) were studied in 34 patients with AMI who were undergoing thrombolytic and heparin therapy. They were classified into 6 groups accordingto their stage of treatment: group 1, before intravenous administration of 800.000 U streptokinase over 30 min; group 2, after a<Mnistraticn of SK but before adninistraticn of heparin; group 3, during 24 h ofthe 5 ng/h heparin continuous infusion; group 4, during 48-72 h of the 16.6 ng/h heparin continuous infhsion; group 5, after 1 week of administration of SK and with a bolus inyection of 50 rg heparin every 4 h; group 6, patients who were undergoing only heparin treatment. The Fg 1/ Fg II ratio varies during treatment with SK and heparin. In group 1 a sligjnt increase (2.5) is observed. Group 2 shows a significantdecrease (0.6) as a result of fibrinolysis. In group3 the ratio reaches normal value (1.8) while in the fourth group it is twice the normal value (4). The value for group 5 is nearly normal (2.1), and in group 6 it reaches values similar to those obtained in group 4, which implies that the rise in the Fgl/Fgll ratio is not a result of fibrinolytic treatment. TheFPA level shows and increase in patients with AMI (group 1,126 ng/ml). When SK treatment is applied (group 2), FPA decreases to 52 ng/ml. Later treatment with heparin (group-3, 82; group-4, 44 and group-5, 81ng/ml) does not neutralize thrcmbinic activity. Patients treated only with heparin (group 6) show an FPAvalue of 19 ng/ml, which is lower than in the other groups. All of this indicates that thrombin is activated after fibrinolytic treatment. FDP values show asignificant increase in the six groups (1, 53; 2, 430; 3, 128; 4, 270; 5, 139 and 6, 141 ug/ml), which indicates that during treatment with heparin the fibrinolytic activity persists. he formation of highly cross-linked fibrin is altered in groups 1,2,3 and 4,as a consequence of circulating FDP effect and fibrincgeno- lysis.The permeability of the fibrin clotdecreases in groups 1 (0.42), 2 (1.3), 4 (1.1) and 5(0.5 ml/s/ng) and increases in group 2 (23.2 ml/s/nig) with respect to the normal plasma value (3.2 ml/s/nrg). The decrease in permeability must be related to the existence of hypercoagulability resistant to heparinization. FPA values, tine Fgl/Fgll ratio, andfibrin permeability can be used to evaluate the degree of thrcmbin activity during thrombolytic treatmentinAMI.

Abstract Aim The purpose of this study was to evaluate the fracture resistance of endodontically treated maxillary central incisors restored with quartz fiber posts, composite cores, and crowns when different types of ferrule designs were incorporated. Methods and Materials Sixty maxillary incisors were divided into six groups: Group 1 (control): teeth with root canal treatments having a full crown prosthesis; Group 2: teeth with a 2 mm circumferential ferrule; Group 3: teeth with a 2 mm ferrule only in the vestibular region; Group 4: teeth with a 2 mm ferrule only in the palatal region; Group 5: teeth with a 2 mm ferrule in the vestibular and palatal region, having cavities in both proximal areas; and Group 6: teeth with no ferrule. The teeth in the experimental groups were restored with quartz fiber posts-composite cores and full metallic crowns. All experimental teeth were subjected to an increasing compressive force with a crosshead speed of 1 mm/min, until fracture occurred. Results The median fracture values of groups were as follows: Group 1: 574.4 N, Group 2: 472.4 N, Group 3: 474.3 N, Group 4: 480.7 N, Group 5: 463.1 N, and Group 6: 297.9 N. A statistically significant difference was found between Group 1 and Group 6 (p< 0.01). Conclusion It was concluded different ferrule designs did not have any influence on the fracture resistance of teeth with fiber posts. The results of this study indicate fiber posts can safely be used for their reinforcing properties. Furthermore, there is no significant change in the resistance of teeth with fiber posts regardless of which ferrule design is incorporated. The property of these types of posts is an additional advantage in clinical practice. Citation Dikbas I, Tanalp J, Ozel E, Koksal T, Ersoy M.

Abstract Aim: To establish the correlation between intraocular pressure (IOP) and thickness of extraocular muscles (EOM), the severity and activity of thyroid-associated orbitopathy (TAO). Materials and methods: 50 patients with TAO were included in the study. They all underwent a thorough ophthalmic examination, Goldmann tonometry (mm Hg) and computer tomography of the orbits, the muscle thickness sum (MTS) of each eye being measured in millimeters. According to the activity of TAO, the patients were divided into two groups – with and without activity, and according to the severity of the disease – into 6 groups: Group 1 (‘O’) had only subjective symptoms, group 2 (‘S’) had soft tissue symptoms, group 3 (‘P’) – proptosis, group 4 (‘E’) – ocular motility disorders, group 5 (‘C’) – corneal damage, and group 6 (‘Si’) – visual impairment; Results: TAO activity was registered in 21 patients (42 eyes, 42%) with MTS 23.39±3.81 and IOP 18.43±4.16. Twenty-nine patients (58 eyes, 58%) with MTS 19±3.21 and IOP 15.98±4.59 showed no TAO activity. The IOP within the groups, in terms of severity, was as follows: group 1 – 19.92+4.05; group 2 – 14.5±2.55; group 3 – 18.04±4.51; group 4 – 18.2±5.05; group 5 – 20.5±4.5; group 6 – 21.5±4.95. A correlation between the IOP and MTS was found. Conclusions: The IOP in patients with TAO depends on the thickness of the EOM, as well as on the activity and severity of the disease.

Background Dilute Russell’s viper venom time (dRVVT) is indispensible in lupus anticoagulant (LA) detection yet commercial reagents from different suppliers perform variably, no gold standard assays exist and therapeutic anticoagulation interference is problematic. Objective The objective of this study was to compare a new formulation dRVVT with two currently available dRVVTs. Materials and methods Life Diagnostics (LD) dRVVT and Stago PTT-LA were routinely used for lupus anticoagulant detection, plus Taipan snake venom time/ecarin time (TSVT/ET) for patients on warfarin or rivaroxaban. Siemens dRVVT and the new HYPHEN BioMed (HBM) dRVVT were tested with 193 patient samples. Group 1, 59 non-anticoagulated patients (NAPs) LA-positive in LD dRVVT; Group 2, 15 PTT-LA-positive/dRVVT-negative NAPs; Group 3, 24 LA-positive warfarinized patients; Group 4, 13 patients on rivaroxaban; Group 5, 62 LA-negative thrombotic NAPs; Group 6, 20 warfarinized, non-antiphospholipid syndrome patients. Results Accepting that the Life Diagnostics reagents were acting as a pseudo-gold standard, Siemens dRVVT detected 56/59, (95%) Group 1 LA and HBM dRVVT 46/59, (76%), one each from Group 2, and Siemens dRVVT detected one in Group 5. The lower HBM dRVVT detection rate mainly concerned weaker LA, where between-reagent concordance is problematic. All Group 3 patients appeared LA-positive in undiluted plasma with Siemens dRVVT, as did 16/24 (67%) with HBM dRVVT but the fewer LA-positives in mixing tests better mapped to clear LA-positives with LD dRVVT. LD and Siemens dRVVTs exhibited 87% and 95% false-positivity for Group 6 whilst HBM dRVVT had none. Increasing the cut-off improved accuracy. Applying higher cut-offs improved accuracy in Group 4 patients. Conclusion HBM dRVVT exhibited improved specificity, mainly due to less interference by anticoagulation, but reduced sensitivity, compared to the other dRVVTs employed.

Animal models for adhesion induction are heterogeneous and often poorly described. We compare and discuss different models to induce peritoneal adhesions in a randomized, experimental in vivo animal study with 72 female Wistar rats. Six different standardized techniques for peritoneal trauma were used: brushing of peritoneal sidewall and uterine horns (group 1), brushing of parietal peritoneum only (group 2), sharp excision of parietal peritoneum closed with interrupted sutures (group 3), ischemic buttons by grasping the parietal peritoneum and ligating the base with Vicryl suture (group 4), bipolar electrocoagulation of the peritoneum (group 5), and traumatisation by electrocoagulation followed by closure of the resulting peritoneal defect using Vicryl sutures (group 6). Upon second look, there were significant differences in the adhesion incidence between the groups (P<0.01). Analysis of the fraction of adhesions showed that groups 2 (0%) and 5 (4%) were significantly less than the other groups (P<0.01). Furthermore, group 6 (69%) was significantly higher than group 1 (48%) (P<0.05) and group 4 (47%) (P<0.05). There was no difference between group 3 (60%) and group 6 (P=0.2). From a clinical viewpoint, comparison of different electrocoagulation modes and pharmaceutical adhesion barriers is possible with standardised models.

Abstract Abstract 3378 Chronic Myelogenous Leukemia (CML) originates in the Philadelphia chromosome, a reciprocal translocation creating the fusion oncogene BCR-ABL. In 1–2% of CML cases, breakpoints fall outside the M-BCR gene on chromosome 22, leading to the synthesis of a variety of atypical BCR-ABL transcripts [shortened: e1a2 (m-BCR), e6a2, e8a2, b2a3 (e13a3), b3a3 (e14a3), or elongated transcripts: e19a2 (m-BCR)] and to the synthesis of different molecular weight BCR-ABL proteins that might have different tyrosine kinase activities. Thus, clinical phenotypes and BCR-ABL inhibition by tyrosine kinase inhibitors might be different and lead to different prognostic features. We retrospectively analysed at the national level, the clinical characteristics and the responses to imatinib (IM) of 63 patients with CML harbouring atypical BCR-ABL transcripts: 22 e1a2 [Group 1 (G1)], 20 e19a2 [Group 2 (G2)], 5 e8a2 [Group 3 (G3)], 4 e6a2 [Group 4 (G4)], 5 b2a3 [Group 5 (G5)], and 3 b3a3 [Group 6 (G6)] BCR-ABL transcripts. The general characteristics of the patients and their best response to IM are depicted in Table 1: Table 1 Group 1(e1a2) Group 2 (e19a2) Group 3 (e8a2) Group 4 (e6a2) Group 5 (b2a3) Group 6 (b3a3) n 22 20 5 8 5 3 M/F 7/15 6/14 4/1 4/4 5/0 0/3 Median age (years) 70 69 43 57 62 47 CP/AccP/MBC 20/0/2 17/1/2 5/0/0 4/1/3 4/1/0 2/1/0 Sokal (L/H/I/Ukn)* 6/8/2/4 1/3/9/4 3/1/0/1 1/2/1/0 1/2/0/1 0/2/0/0 Leukocytes (G/l, median) 60.85 28.3 55 28.4 93 82.4 Hemoglobin (g/dl, median) 12 10.2 11.7 10.95 11.1 10.2 Platelets (G/l, median) 303 848 253 259 167 363 Monocytes (G/l median) 4.8 0.8 2.34 0.05 1.08 0.825 Additional Clonal Abnormalities at diag (% of patients) 20 28 0 29 25 0 IM duration (median, years) 1.55 1.38 1.58 0.8 1.13 1.42 Interval Diagnosis-IM (median, years) 1.31 1.48 1 1.17 0.87 1.66 Best response to IM* No response 20 0 0 0 0 0 CHR (%) 13 32 0 0 0 0 Minor CyR (%) 47 0 0 0 0 0 PCyR (%) 0 10 20 10 25 67 CCyR (%) 13 32 60 50 0 0 MMR (%) 7 26 20 40 75 33 Follow-up since diag (median, years) 3.24 1.57 1.6 3.82 1.5 1.68 (CP states for Chronic phase, AccP for accelerated phase, MBC for myeloid blast crisis, L for Low, I for intermediate, H for High, Ukn for Unknown, * For CP patients only) Surprisingly, e1a2 and e19a2 transcripts seem significantly more frequent in females than in males conversely to typical BCR-ABL transcripts (p=0.01) and occurring more often in the elderly (p=0.05). The majority of the patients presented with typical cytological CML features, however, a significant monocytosis was observed in e1a2 and e8a2 atypical transcripts (p=0.0002). The median time on IM and the interval between diagnosis and IM were not statistically different between the 6 groups. Overall, there was no significant difference in the (hematologic, cytogenetic, molecular) responses to IM, but e1a2 transcripts seem less sensitive to this agent. The overall survival since diagnosis or since IM initiation was not different between atypical transcripts (p=0.55 and p=0.73 respectively), however, the progression-free survival (PFS) since diagnosis with e1a2 transcripts was significantly worse than for all other atypical transcripts (p=0.02) as shown in Figure 1: The PFS since IM initiation was somewhat worse for e1a2 transcripts, but close to significance (p=0.09), but the follow-up is not very long yet. Fifteen patients among 63 had second generation TKIs (TKI2), 7 in group 1, 3 in group 2, 1 in groups 3, 4, 5, and 2 in group 6. Only one patient (b3a3 transcript) developed a MBC being on IM. Two patients developed a T315I BCR-ABL mutation (1 e1a2, and 1 e6a2). Two patients got allo-transplanted (1 e1a2 alive and well at last follow-up, 1 e19 a2 died from GVHD). In conclusion, atypical BCR-ABL transcripts induce a particular molecular and subsequent clinical phenotypes, particularly e1a2 transcripts showing in this study poor prognosis features. The response of atypical BCR-ABL transcripts to IM might vary from that what it is for classical M-BCR transcripts, but a longer follow-up is needed. Disclosures: No relevant conflicts of interest to declare.

BACKGROUND: The circle of Willis (CW) is an important network of collaterals that provide compensatory redistribution of hemodynamic load. Several studies showed that the CW is open in approximately 50%90% of cases, and the number of missing segments correlates with low brain tolerance to ischemia in internal carotid artery (ICA) compression. Currently, studies dedicated to the relationship of different configurations of CW with the risk of ischemic brain damage. AIM: The analyze the immediate results of eversion carotid endarterectomy (CEA) in patients with different configurations of the structure of the CW. MATERIALS AND METHODS: We included 641 patients with hemodynamically significant stenosis of the internal carotid arteries (ICA) in a study period from 2010 to 2020. All patients underwent multispiral computed tomography with angiography of the extracranial and CW arteries. Based on the structural variants of the CW, six groups of patients were studied: group 1 (64.9%, n = 416) closed posterior part (CPP) with the existence of posterior communicative artery (PCA) and P1 segment of the posterior cerebral artery (PCerA); group 2 (27%, n = 173) an intermediate structure of the posterior part (IPP) with hypoplasia of the PCA or PCerA; group 3 (8.1%, n = 52) open posterior part (OPP) with the absence of PCA or PCerA; group 4 (85.95%, n = 551) closed anterior part (CAP) with the presence of the anterior communicating artery (ACA) and A1 segment of the anterior cerebral artery (ACerA); group 5 (7.95%, n = 51) an intermediate structure of the anterior part (IAP) with hypoplasia of ACA or ACerA; group 6 (6.1%, n = 39) open anterior part (OAP) with the absence of ACA or ACerA. To assess the compensatory potentials of the brain, all patients underwent measurement of the retrograde pressure in the ICA and intraoperative cerebral oximetry. RESULTS: In the postoperative period, 1 death was recorded in group 4 (CAP) due to a hemorrhagic transformation in the zone of ischemic stroke, on the background development of hyperperfusion syndrome. The largest number of ischemic strokes of the cardioembolic subtype was diagnosed in the ACerA territory in the presence of an unstable atherosclerotic plaque: group 1 (CPP) 0%; group 2 (IPP) 0%; group 3 (OPP) 0.24%, n = 1; group 4 (CAP) 0.18%, n = 1; group 5 (IAP) 1.96%, n = 1; group 6 (OAP) 5.1%, n = 2; p 0.9999. The probable cause was embolization against the background increase in the arterial pressure before ICA clamping. In turn, the majority of ischemic strokes of the hemodynamic subtype developed in the territory of PCerA: group 1 (CPP) 0%; group 2 (IPP) 1.73%, n = 3; group 3 (OPP) 3.8%, n = 2; group 4 (CAP) 0.18%, n = 1; group 5 (IAP) 0%; group 6 (OAP) 2.56%, n = 1; p 0.9999. This pattern coincided with the largest number of patients with CW of the IPP and OPP types among all open variants of the structure. CONCLUSION: Parameters of retrograde pressure in the ICA and intraoperative cerebral oximetry do not always demonstrate the need for a temporary shunt (TS). Due to the opened structure of CW, the redistribution of blood flow occurs with the formation of zones of hypo- and hyperperfusion, causing ischemic alterations in the brain matter. Thus, in order to maintain adequate cerebral hemodynamics, to mitigate the effect of hypo- and hyperperfusion, and reduce the risk of ischemic stroke, the open variant of the CW structure should be considered as an indication for a TS.

Objectives: To determine the impact of exposure to second hand smoking on fetal birth weight and length. Study Design: Comparative Cross Sectional study. Setting: Physiology Department of Shaikh Zayed Postgraduate Medical Institute. Period: December 2015 to May 2016. Material & Methods: Non-probability convenience sampling was used to collect data from 120 women and their neonates, who were further divided in four equal groups based on level of exposure to second hand smoking. A self-administered questionnaire was used to collect data regarding level of exposure of mothers, while weight and length of neonates were measured objectively. Results: Mean birth weight (kg) in group-1 was 3.31 ± 0.50, in group-2 was 3.00 ± 0.28, in group-3 was 2.92 ± 0.48 and in group-4 was 2.66 ± 0.41. The p-value calculated by one way ANOVA was 0.001 which shows that birth weight was significantly different in all the groups. Mean birth weight of neonates showed inverse relation with SHS exposure of the mothers. Mean length (cm) of neonates in group-1 was 49.30 ± 1.70, in group-2 was 48.77 ± 1.47, in group-3 was 49.40 ± 2.12 and in group-4 was 48.53 ± 1.65. It was seen that there was no significant difference in length of neonates belonging to different groups. Incidence of low birth weight among all the groups was 11.6%. Conclusion: Second hand smoking of mothers affects birth weight of neonates which in turn influence the intellectual abilities and developmental milestones of neonates. Awareness should be made in society in this regard to prevent the burden of the disease in silent victims of smoking.

Background: We hypothesized that perioperative HbA1c influenced the pattern and outcomes of Lower Extremity Amputation (LEA). Methods: A retrospective analysis was conducted for all patients who underwent LEA between 2000 and 2013. Patients were categorized into 5 groups according to their perioperative HbA1c values [Group 1 (<6.5%), Group 2 (6.5-7.4%), Group 3 (7.5-8.4%), Group 4 (8.5-9.4%) and Group 5 (≥9.5%)]. We identified 848 patients with LEA; perioperative HbA1c levels were available in 547 cases (Group 1: 18.8%, Group 2: 17.7%, Group 3: 15.0%, Group 4: 13.5% and Group 5: 34.9%). Major amputation was performed in 35%, 32%, 22%, 10.8% and 13.6%, respectively. Results: The overall mortality was 36.5%; of that one quarter occurred during the index hospitalization. Mortality was higher in Group 1 (57.4%) compared with Groups 2-5 (46.9%, 38.3%, 36.1% and 31.2%, respectively, p=0.001). Cox regression analysis showed that poor glycemic control (Group 4 and 5) had lower risk of mortality post-LEA [hazard ratio 0.57 (95% CI 0.35-0.93) and hazard ratio 0.46 (95% CI 0.31-0.69)]; this mortality risk persisted even after adjustment for age and sex but was statistically insignificant. The rate of LEA was greater among poor glycemic control patients; however, the mortality was higher among patients with tight control. Conclusion: The effects of HbA1c on the immediate and long-term LEA outcomes and its therapeutic implications need further investigation.
