Item The Influence of Different Sugammadex Doses on Neural Tube Development in Early-Stage Chick Embryos(2023) Ayhan, Asude; Efe, Ekin; Fidan, Pinar A.; Efe, Oguzhan E.; Ates, Eylem Gul; Sahinturk, Fikret; Ayhan, Selim; 0000-0002-6166-2601; 0000-0001-6955-9839; 0000-0002-3243-7843; 0000-0003-3047-0305; 0000-0002-0471-3177; 37565787; HGE-9282-2022; AAJ-2057-2021; AAJ-4728-2021; W-7908-2019; ABG-5365-2020; AAI-7972-2021Background: Sugammadex is a modified gamma-cyclodextrin that has been developed with the goal of reversing the steroidal neuromuscular blocking agents. The aim of the present study is to investigate the effects of different sugammadex doses on embryologic and neural tube development in an early-stage chick embryo model. Methods: A total of 100 specific pathogen-free, fertilized domestic chicken eggs were randomly divided into five groups (n = 20, each), and placed in an automatic cycle incubator. The eggs in the "control (C)" group were incubated without administration of any drug till the end of the experiment. Subblastodermic administration of 0.9% NaCl as vehicle control (VC) and different doses of sugammadex solutions prepared with the latter [2 mg/mL (LD), 4 mg/mL (MD), 16 mg/mL (HD)] were performed at 30 hr of incubation. All embryos were removed from the eggs at 72 hr when they were expected to reach Hamburger-Hamilton (HH) stages 19-20, then they were fixed, and evaluated histo-morphologically. Results: Embryonic development was not observed in 11 eggs (1 in C, 1 in VC; 3 in LD, 3 in MD, and 3 in HD). All the developed embryos were compatible with the HH stages 19-20. A neural tube closure defect was detected in one embryo in the HD group. No statistically significant difference was found between the groups in terms of embryonic and neural tube developments. Conclusions: No significant association was found between the drug and adverse outcomes; however, a trend with dosing was seen. Further studies are required before conclude on safety and extrapolate these results to human beings.Item Fertility Outcomes of Patients with Early Stage Endometrial Carcinoma(2014) Parlakgumus, Huriye Ayse; Kilicdag, Esra Bulgan; Simsek, Erhan; Haydardedeoglu, Bulent; Cok, Tayfun; Aytac, Pinar Caglar; Bagis, Tayfun; Erkanli, Serkan; https://orcid.org/0000-0002-0942-9108; https://orcid.org/0000-0003-1244-7419; 24033512; AAK-8872-2021; AAH-5686-2020; AAC-9940-2020AimThree to five percent of endometrial carcinoma patients are younger than 40 years and may desire fertility. Conservative treatment can be employed in these cases. We aimed to review treatment outcomes of patients who were diagnosed with endometrial carcinoma and who wanted to preserve their fertility. Material and MethodsWe reviewed nine patients who were diagnosed with early stage endometrial carcinoma and wanted to spare their fertility. The patients were followed up at Baskent University Adana Research Center from January 2004 to December 2011. ResultsIn all patients the carcinoma presented as polyps, which were resected by hysteroscopy. After being informed about both surgical and medical therapies, four patients preferred surgery and five preferred medical treatment. The mean number of in vitro fertilization trials after conservative treatment was 3.25. One woman, who was on medroxyprogesterone acetate, delivered a healthy term baby from a fresh cycle. Another woman, who was on dydrogesterone, got pregnant from a thawing cycle, which later ended up in a missed abortus. Of all the patients who chose medical treatment, three had surgery at the end. One woman developed an ovarian tumor during the follow-up; one woman had a recurrence of endometrial carcinoma on dilatation and curettage for missed abortus and one woman tried in vitro fertilization several times and could not get pregnant, thus decided to have surgery. Two women had stage IA endometrial carcinoma and one had stage IIB ovarian carcinoma. ConclusionConservative treatment of endometrial carcinoma is safe in most cases. However, patients should be well-informed about the risks of conservative treatment because delaying definitive treatment sometimes worsens the prognosis.Item The Use of ERCP during Pregnancy: Is it Safe and Effective?(2014) Akcakaya, Adem; Koc, Bora; Adas, Gokhan; Kemik, Ozgur; 24901127Cholangitis and pancreatitis are the most gruesome complications that can be potentially fatal for the mother and fetus. The management of bile stone disease complicated with duct stones during pregnancy is challenging. Conservative treatment instead of surgery has always been advocated due to the increased risk for fetal compromise. Minimally invasive therapy with ERCP has been suggested as an effective therapeutic option for the management of pancreaticobiliary diseases during pregnancy. The main topics of discussion are the risks stemming from the endoscopic procedure itself, drugs used for sedation and the adverse effects of radiation exposure on the fetus. In this manuscript, we want to present the efficiency and feasibility of the ERCP for the management of hepatobiliary and pancreatic diseases in pregnancy.Item Anti-N-Methyl-D-Aspartate Receptor Encephalitis During Pregnancy: A Case Report(2019) Keskin, Ahmet O.; Tanburoglu, Anil; Idiman, Egemen; Ozturk, Vesile; https://orcid.org/0000-0002-2942-323X; https://orcid.org/0000-0001-9627-3502; 30788880; AAJ-2044-2021; AAK-1876-2021Following a generalized tonic-clonic seizure, a previously healthy 27-year-old pregnant woman (18-week pregnancy) was admitted to our emergency department. She experienced lethargy, forgetfulness and persecutory hallucinations the day before hospitalization. Cerebrospinal fluid examination revealed moderate pleocytosis, and abdominal ultrasonography did not detect neoplasia. Orofacial dyskinesia, catatonia and central hypoventilation gradually developed despite medical intervention to ameliorate the symptoms. At 32 weeks of pregnancy, vaginal bleeding and hypotension occurred. Further, owing to septic shock due to fetal demise, the patient died. N-methyl-d-aspartate antibody test results obtained after the patient's death were positive (2++). Currently, no consensus exists on the appropriate treatment and follow-up for pregnant women with anti-N-methyl-d-aspartate receptor encephalitis; however, immunomodulators and teratoma resection may be helpful. Second line immunotherapy (rituximab, cyclophosphamide) and teratoma resection may be necessary in pregnant patients with high N-methyl-d-aspartate receptor antibody titers and inadequate response to first-line treatment.Item Effects of Ciprofloxacin on Fetal Rat Liver During Pregnancy and Protective Effects of Quercetin(2017) Dogan, Z.; Elbe, H.; Taslidere, E.; Soysal, H.; Cetin, A.; Demirtas, S.; 0000-0001-7131-2317; 0000-0003-1723-2556; 28836867; V-5131-2018; ABI-8046-2020; AAL-4660-2020Urinary tract infections are common in pregnant women and ciprofloxacin frequently is used as a broad spectrum antibiotic. It has been suggested that ciprofloxacin causes liver damage in fetuses. Quercetin is a flavonoid with antioxidant properties. We investigated the efficacy of quercetin treatment for preventing fetal liver damage caused by ciprofloxacin. Pregnant rats were divided into four groups: untreated control group (C), 20 mg/kg quercetin for 21 days group (Q), 20 mg/kg twice/day ciprofloxacin for 10 days group (CP), and 20 mg/kg, ciprofloxacin + quercetin for 21 days group (CP + Q). Fetal livers were removed on day 21 of gestation to measure antioxidants and for histological observation. Malondialdehyde (MDA) and glutathione (GSH) levels, and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities were measured in tissue samples. GSH-Px, SOD and CAT activities were significantly lower in the CP group compared to group C. A significant increase in MDA was observed in the CP group compared to group C. There was no significant difference in GSH levels in any group. MDA levels were lower and CAT, SOD and GSH-Px enzyme activities were higher in the CP + Q group compared to group CP. Liver samples of the CP group exhibited central vein dilation, portal vein congestion, pyknotic nuclei and cytoplasmic vacuolization in some hepatocytes. Histological changes were less prominent in the rats treated with quercetin. Use of ciprofloxacin during pregnancy caused oxidative damage in fetal liver tissue. Oxidative stress was ameliorated by quercetin. Quercetin supports the antioxidant defense mechanism and it is beneficial for treating fetal liver damage caused by ciprofloxacin.Item Is Late Adolescence A Real Risk Factor for An Adverse Outcome of Pregnancy?(2016) Ozdemirci, Safak; Kasapoglu, Taner; Cirik, Derya Akdag; Yerebasmaz, Neslihan; Kayikcioglu, Fulya; Salgur, Funda; 0000-0001-5502-7751; 26767509; AAE-7154-2021; AAI-8762-2021Objective: To compare the obstetrical and neonatal outcomes of late adolescent (LA) and adult pregnancies.Methods: Between January 2012 and December 2012, a total of 313 late adolescent pregnant aged between 16 and 19 years and 418 adult pregnant women aged between 20 and 35 years having given birth in our maternity service were enrolled into this case-control study. The demographic and clinical data were reviewed from hospital database and patients' medical records.Results: The incidence of preterm birth (PB) in the LA group was significantly higher than in the adult group (p=0.001), while the incidence of gestational diabetes mellitus was significantly lower (p=0.001). The mean birth weight and the rate of delivered macrosomic fetuses in the study group were lower than in the control group (p=0.03). The LA group had significantly higher rate of vaginal delivery when compared to the adult group (p=0.001). Both the rate of pregnancy induced hypertensive disorders and postpartum hemorrhage were not statistically different between the two groups (p=0.31; p=0.38, respectively). The LA group had lower rate of stillbirth when compared to the adult group; however, the difference was statistically insignificant (0.3% versus 1.2%) (p=0.24).Conclusions: The LA pregnancy should be closely followed up during their antenatal care period due to the significantly higher rate of PB.Item Hemolysis, Elevated Liver Enzymes and Low Platelet Syndrome: Outcomes for Patients Admitted to Intensive Care at A Tertiary Referral Hospital(2017) Gedik, Ender; Yucel, Neslihan; Sahin, Taylan; Koca, Erdinc; Colak, Yusuf Ziya; Togal, Turkan; https://orcid.org/0000-0002-7175-207X; https://orcid.org/0000-0001-5845-2614; 27599183; ABI-2971-2020; ABI-3412-2020Purpose: The aim was to assess outcomes for pregnancies in which hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome develops and the patient requires transfer for critical care. Materials and Methods: The cases of women with HELLP syndrome who delivered at our tertiary center or surrounding hospitals and were admitted to the intensive care between January 2007 and July 2012 were retrospectively analyzed. Results were compared for the surviving and non-surviving patients. Results: Among the 77 women with HELLP syndrome, maternal mortality rate was 14% and 24 (30%) of 81 fetuses and newborns died in the perinatal period. The most common maternal complications were disseminated intravascular coagulation (DIC) (n = 22; 29%), acute renal failure (n = 19; 25%), and postpartum hemorrhage (n = 16; 21%). Compared with surviving women, the non-surviving women had higher mean international normalized ratio (INR) (p < 0.0001); higher mean serum levels of aspartate aminotransferase (AST) (p < 0.0001); higher alanine aminotransferase (ALT) (p < 0.0001); higher lactate dehydrogenase (LDH) (p < 0.0001), and higher bilirubin (p = 0.040) levels; and lower platelet count (p = 0.005). Conclusion: DIC is a major risk factor for maternal outcome among patients with HELLP syndrome who require intensive care. Low platelet count; high AST, ALT, LDH, INR; and total bilirubin are associated with high mortality risk in this patient group. In addition, low platelet count; low fibrinogen level; prolonged activated thromboplastin time; high INR; and high total bilirubin, LDH, blood urea nitrogen, and creatinine are associated with high risk for complications in this patient group.Item The Role of Personality Traits on Mode of Delivery(2021) Okten, Sabri Berkem; Gunduz, Anil; Sencelikel, Tugce; Desteli, Guldeniz; Gunduz, Elvan Basak Usta; Bildaci, Tevfik Berk; 0000-0001-7473-761X; 0000-0002-5159-238X; 0000-0002-3883-1964; 33541178Purpose The aim of this study is to understand the motives behind CS requests in nulliparous women in their late pregnancy better and to investigate if specific personality traits affect the maternal decision on mode of delivery. Material and Method This prospective study was conducted with 70 healthy, nulliparous parturient with singleton pregnancies. Women at their 28-32. weeks of gestation were asked to fill a socio-demographic data form and the questionnaires; Personality Belief Questionnaire - Short Form (PBQ-SF) and The Childbirth Attitudes Questionnaire (CAQ). After delivery, all the results of pre-filled questionnaires and women's mode of delivery were analyzed and compared. Results There were significant differences in personality types; dependent (p = 0.033), passive-aggressive (p = 0.031), obsessive-compulsive (p = 0.001), antisocial (p = 0.014), narcissistic (p = 0.014) and borderline (p = 0.014) between vaginal delivery and CS groups. The CAQ scores of the mothers who requested CS were significantly higher (p:0.007). Weak but significant positive relation was found between total CAQ scores and avoidant (p = 0.022), dependent (p = 0.034), passive-aggressive (p = 0.040), narcissistic (p = 0,006), schizoid (p = 0.007), paranoid (p = 0.007) and borderline (p = 0.007) personality types. Conclusion This is the first study that investigates the relationship between mode of delivery and personality traits according to the Diagnostic and Statistical Manual of Mental Disorders (DSM) and cognitive behavioral perspective in the literature. These personality traits can be carried at a level that is not clinically significant to create an obvious pathology, yet they might play a role as the motives behind the apparent reasons for women who request CS. Understanding women's motives and attitudes for childbirth during their pregnancy may help healthcare providers to tailor women's approach to childbirth to avoid unnecessary CS.Item How safe is pregnancy after liver transplantation? A large case series study at tertiary referral center in Turkey(2020) Gulumser, Cagri; Kinap, Mahir; Yanik, Filiz Bilgin; Uysal, Nihal Sahin; Moray, Gokhan; Haberal, Mehmet; 0000-0002-3462-7632; 0000-0003-2498-7287; 0000-0001-5385-5502; 0000-0002-4066-9038; 30227751; AAJ-8097-2021; AAE-1041-2021; AAA-9475-2020; C-6543-2018Objective: To investigate pregnancy outcomes and to define preventative measures against to risk factors and complications in pregnancy after liver transplantation. Secondary aim is to report postpartum allograft functions in these patients. Method: This is a case series study. All pregnant women with liver transplantations performed in our hospital were enrolled. Patients' hospital medical records, electronic records Neonatal Intensive Care Unit (NICU) records were used to collect data. Obstetric characteristics and antenatal complications, risk factors, pregnancy and neonatal outcomes, all aspects of liver transplant variables and allograft functions after pregnancy were studied. Results: A total of 11 patients were included in the study. All of them were singleton. Mean maternal age was 29.3 +/- 3.9 years. And mean gestational week of delivery was 37.2 +/- 2.2. 78% of the women were delivered at term (>37 weeks) only two babies were preterm and discharged from NICU without any complications. Birth weight (gr median +/- SD) was 2575 +/- 345. Five (45%) patients were nulliparous, majority of the cases (8/11, 72%) were conceived of pregnant with natural way. Live birth rate was 81% (9/11). Only one patient for each has suffered from fetal growth restriction, maternal anemia, maternal hyperthyroidism, and ulcerative colitis. Vaginal bleeding was seen in five women during the pregnancy. There was no maternal death, stillbirth or neonatal death. The mode of delivery for all live birth pregnancies was C-section. And none of them was emergency C-section. No complication of allograft function was seen after pregnancy. Conclusion: Pregnancy in women with liver transplantation is not associated with poor pregnancy outcomes and complications for both the mother and the neonates when these patients followed up at tertiary referral center with multidisciplinary approaches.Item Reappraisal of the relationship between 24-hour proteinuria and preeclampsia in terms of the maternal and perinatal outcomes(2020) Yilmaz Baran, Safak; Alemdaroglu, Songul; Durdag, Gulsen Dogan; Yetkinel, Selcuk; Yuksel Simsek, Seda; Kalayci, Hakan; Simsek, Erhan; 0000-0003-4335-6659; 0000-0002-5064-5267; 0000-0002-2165-9168; 32037908; AAK-7016-2021; AAK-7016-2021; AAK-7016-2021; AAK-7016-2021; AAK-7016-2021Objective: This study evaluated the association between proteinuria levels and maternal, and perinatal outcomes of preeclampsia patients and determined the cutoff values for predicting severe complications. Methods: We retrospectively evaluated the records of 412 patients with proteinuric preeclampsia. Results: Median proteinuria levels were significantly higher in patients with severe maternal and adverse perinatal outcomes than in those without such outcomes, except in cases of placental abruption and late preterm delivery. Conclusion: Proteinuria levels may aid in diagnosing preeclampsia and indicating early intervention. The revised guidelines do not suggest that proteinuria encountered during pregnancy is clinically insignificant.
