Examining of immigrant entrepreneurship studies in international literature by using social network analysis

Immigrant entrepreneurship is increasingly becoming part of the global economy which is garnering more attention from different academic disciplines. The increase in numbers of immigrants all over the world, especially in recent times, has also led to an increase in the immigrant entrepreneurship. Socio-cultural and economic impacts of this increase begin to draw attention of researchers studying the economy and business. However, analyzing the studies about immigrant entrepreneurship phenomenon systematically is quite limited. In this context, the aim of the study is to reveal knowledge network of immigrant entrepreneurship and show slightly-used paths of this field as suggestions for further studies. To achieve this aim, social network analysis (SNA) providing linkages and connections about immigrant entrepreneurship is used. Likewise SNA method is commonly used in scientific researches to provide a powerful set of tools for describing and linking information. Articles about immigrant entrepreneurship published in journals which are involved in SSCI are evaluated and UCINET software is used for visualizing our research through keywords. The study is expected to contribute to the business literature generally and entrepreneurship literature specifically and lead to researchers who aim to study the immigrant entrepreneurship by means of focusing on gaps and variables which are not discoursed adequately in the field

Maternal-fetal outcome associated with adolescent pregnancy in a tertiary referral center: a cross-sectional study

Objectives: This study was conducted to compare pregnancy outcomes of early-middle adolescent, late adolescent and adult women. Material and methods: The study focused on early-middle adolescent (n = 145), late adolescent (n = 1655) and adult (n = 1585) women who gave birth during 2014 through 2017, utilizing data obtained from the Zeynep Kamil Women and Children’s Health Training and Research Hospital. Pregnancy outcomes were determined according to the rates of preg¬nancy complications, including method of delivery, birth weight, as well as the rate of newborn intensive care admissions. Results: Comparisons between the studied groups for various pregnancy complications showed highest rates of pre¬term deliveries (PD), preterm premature rupture of membranes (PPROM) and neonatal intensive care unit admission in early-middle adolescent group, whereas the highest cesarean section rates were observed in the adult group (p < 0.001). Conclusions: Analysis of the data revealed that adolescent pregnancy, especially the early-middle adolescent pregnancies, is associated with increased risks of adverse pregnancy outcomes

Effectiveness of tranexamic acid on bleeding in conization

Objective: Bleeding is the most common complication of conization of cervix. Hemostatic sutures, intraoperative ferric subsulfate, or vasopressin can be used when intraoperative bleeding occurred, whereas oral tranexamic acid (TA) may be used for post-operative bleeding. In this study, we aimed to find out whether intraoperative cervical TA administration in patients undergoing conization caused changes in the amount of intraoperative bleeding and post-operative hemogram. Material and Methods: Patients who have undergone cervical conization between January 2019 and July 2019 in Zeynep Kamil Health Application and Research Center Gynecological Diseases and Birth Clinic were evaluated. One hundred and five patients were included to our study. One ampoule of 10% TA was applied cervically to 47 of these patients. Both groups were evaluated in terms of measuring the intraoperative amount of blood in the aspirator, changes in post-operative hb/htc/plt values compared to the pre-operative values, and the rate of post-operative bleeding. Results: In our study, the amount of intraoperative hemorrhage and pre-operative hemoglobin, hematocrit, and platelet values compared to the post-operative values were found to be similar in both groups. Conclusion: Although TA has been shown to be effective on hemorrhage in benign gynecologic operations, menorrhagia, and postpartum hemorrhages, no significant effect on hemorrhage in conization with cervical TA administration has been demonstrated

Retrospective analysis of 14 patients who managed for adnexal torsion during pregnancy

Objective: To assess some clinical characteristics of patients who were treated for adnexal torsion during pregnancy. Methods: Medical records of 14 pregnant women with adnexal torsion who were surgically treated at our hospital between 1st January 2011 to 30th October 2015 were screened. In addition to the demographic features obtained from medical records, presenting complaints, physical examination and ultrasonographic findings, type of surgery, histopathologic findings, route of deliveries and complications were all recorded. Results: Mean age of patients included in the study was 27.8 ± 3.9 years, mean gravidity was 2.8 ± 1.8 and mean gestational age was 14.4 weeks. Most commonly seen complaint was pelvic pain followed by emesis and vomiting. All participants underwent abdominal surgery showing an adnexal mass with a mean volume of 48.4 ± 12.1 cm2. Also all participants underwent Doppler ultrasound assessment showing decreased ovarian blood flow. Among 14 patients, 3 of them were managed by laparoscopy while remaining was treated by laparotomy. Detorsion and cystectomy were performed in 10 patients while detorsion was performed in 3 patients, in 1 patient after detorsion no blood flow was observed therefore salpingo-oophorectomy was performed due to overt necrotic appearance. Most commonly seen histopathologic type was mature cystic teratoma. No operative complication was observed. Conclusion: Adnexal torsion should be kept in mind in pregnant presenting with acute abdominal pain. Early diagnosis and treatment are important for organ preserving surgery

Confounders for Neonatal Intensive Care Unit Admission ın Neonates of Mothers with Preeclampsia

Objective: The aim of this study was to investigate the effect of some maternal and neonatal clinical parameters on the neonatal intensive care unit admission rates of neonates born to mothers who had preeclampsia. Study Design: Study included 402 singleton pregnant women with preeclampsia who admitted to Maternal-Fetal Medicine Unit of Zeynep Kamil Children and Women’s Health Training and Research Hospital. Pregnancies with uterine rupture, chorioamnionitis and congenital malformations were excluded. Some maternal and neonatal clinical characteristics were assessed to predict neonatal intensive care unit admission. Results: Among 402 neonates, 140 (35%) of them had an indication for neonatal intensive care unit admission, among 140 neonates, 136 (97%) of them were preterm neonates. Comparison of groups with and without neonatal intensive care unit admission indicated significant differences between groups in terms of gestational age, Apgar scores at 1st and 5th minutes, birth weight, some maternal laboratory parameters (Hemoglobin, hematocrit, alanine aminotransferase, aspartate aminotransferase, albumin). In multivariate analysis, among all study population, gestational age at delivery, birth weight and Apgar scores were found to be significantly associated with neonatal intensive care unit admission. On the other hand, in subgroup of term neonates, none of the variables was shown to be associated with neonatal intensive care unit admission. Conclusion: Gestational age at delivery and the birth weight are the main risk factors for neonatal intensive care unit admission of neonates born to mothers who had preeclampsia
