RESUMO

OBJECTIVE: Fetal vascular malperfusion is associated with poor perinatal outcomes in women with preeclampsia and gestational diabetes mellitus. The aim of this study was to determine the association between fetal vascular malperfusion score and syncytiotrophoblast basement membrane thickness and clinicopathological variables, such as developing preeclampsia in women with gestational diabetes mellitus. METHODS: This retrospective cohort study included 65 pregnant participants (34 with gestational diabetes mellitus and 31 controls) between January 2019 and January 2022. Gestational diabetes mellitus was diagnosed as ≥2 of 4 elevated values on a 3-h, 100-g oral glucose tolerance test. The fetal vascular malperfusion score was evaluated by endothelial CD34 positivity in the villous stroma of the placenta. The association between fetal vascular malperfusion score and syncytiotrophoblast basement membrane thickness with clinicopathological variables in women with gestational diabetes mellitus was evaluated. RESULTS: It was revealed that the gestational diabetes mellitus group had greater fetal vascular malperfusion scores than the control group (gestational diabetes mellitus group fetal vascular malperfusion score: 34.2±9.1 and control group fetal vascular malperfusion score: 26.5±8.7, respectively, p=0.0009). Syncytiotrophoblast basement membrane thickness was correlated with the development of preeclampsia, trophoblast proliferation, and fetal vascular malperfusions (0.3952, p=0.0129; 0.3487, p=0.0211; and 0.4331, p=0.0082, respectively). On the contrary, fetal vascular malperfusions were correlated with the development of preeclampsia, villous edema, and trophoblast proliferation (0.3154, p=0.0343; 0.2922, p=0.4123; and 0.3142, p=0.0355, respectively). CONCLUSION: The gestational diabetes mellitus group displayed significantly higher fetal vascular malperfusion scores and thickening of the syncytiotrophoblast basement membrane than the control group. There is a correlation between developing preeclampsia and the fetal vascular malperfusion scores and the syncytiotrophoblast basement membrane thickness.

RESUMO

OBJECTIVE: Laparoscopic surgery is the favored method for the surgical treatment of gynecologic diseases and malignancies. We have defined an anatomic landmark-based, easy-to-perform, and an alternative way of open laparoscopic entry technique named the ligamentum teres lift-up technique (TLU) that can be used in obese or normal-weight women to tackle the risks of the closed laparoscopic entry technique, namely, Veress needle entry (VNE). STUDY DESIGN: In this retrospective comparative study, the participants were equally distributed to either the TLU group (n = 36) or the VNE group (n = 36) in a 1:1 ratio. The participants were stratified according to their BMI as follows: BMI between 20-25 kg/m2 (average weight), 25-30 kg/m2 (overweight), 30-35 kg/m2 (class I obesity), and 35-40 kg/m2 (class II obesity). Both laparoscopic access techniques were compared according to the entry time, vascular or visceral injuries, insufflation failures, trocar-related complications, and omental damage. RESULTS: The TLU group had a considerably shorter entry time than the VNE group (74.43 ± 21.45 s versus 192.73 ± 37.93 s; p < 0.001). Only one failed insufflation occurred in the VNE group (p = 0.32); however, that case was successfully insufflated with the TLU technique. Only one intestinal injury was seen in the VNE group, encountered during trocar site closure (p = 0.32). The subgroup analyses of the TLU and VNE groups based on BMI strata revealed a continuation of the statistical significance of entry time between BMI-matched groups. CONCLUSION: The current study reveals that the new alternative TLU technique supplies an alternative, validated, and rapid access to the abdominal cavity in normal-weight and obese women. This new approach offers an easy-to-teach and easy-to-perform technique for surgical mentors and residents in gynecologic and oncologic surgeries.

RESUMO

INTRODUCTION: There has been an increased incidence of macrosomic newborns in the world and most of the macrosomic newborns are born from non-GDM pregnant women. The objective of this study was to determine the frequency and the associated risk factors of fetal macrosomia in non-GDM pregnant women. METHODS: A total 4246 consequtive pregnant women who had no GDM was included the study population. Data was collected from hospital database of Balikesir State Hospital between January 2014 and January 2015. Statistical analysis was carried out using the independent samples t-test and chi-squared test. Logistic regression analysis was used to determine the relationships between associated risk factors and the presence of fetal macrosomia. In this analysis, fetal macrosomia was taken as the dependent variable and associated risk factors were taken as independent variables. Results are shown as odds ratios (ORs) (95% CI) in the logistic regression analysis. RESULTS: 366 of the 4246 pregnant women were diagnosed with fetal macrosomia (8.6%). Compared the control women, a statistically significant correlation between fetal macrosomia and pre-pregnancy body mass index (BMI), gestational weight gain (GWG), parity, advanced maternal age, and male fetal sex was found. Maternal BMI, and GWG were the two risk factors most strongly associated with macrosomia. CONCLUSION: The prevalance of fetal macrosomia is rising among Turkish women. High pre-pregnancy BMI and GWG represent main modifiable risk factors for macrosomia and need more attention from health care providers.

RESUMO

Ovarian cancer is the most common cause of death among all gynecologic malignancies and a result of complex interaction of multiple oncogenes and tumor suppressor genes. The aim of this study was to evaluate expression of HER-2/neu (c-erbB2), survivin and cycline D1 biomarkers in serous ovarian neoplasms and their correlations with clinicopathological variables in serous ovarian cancers. We analyzed pathological specimens of 62 patients with benign (n = 25), borderline (n = 14) and malignant (n = 23) serous ovarian neoplasms. Immunohistochemical analysis was performed on formalin-fixed paraffin-embedded specimens. Significantly more immunoreactivity with HER-2/neu was detected in malignant tumors (100 %) compared to borderline (78.6 %) and benign tumors (48 %) (P < 0.01). Survivin expression was significantly higher in malignant tumors (91.3 %) than those found in borderline (71.4 %) and benign tumors (24 %) (P < 0.001). Similarly, higher cyclin D1 expression was observed in malignant tumors (95.6 %) compared to borderline (85.7 %) and benign tumors (48 %) (P < 0.001). Expression of all biomarkers analyzed significantly and gradually increased from benign to borderline and borderline to malignant serous tumors. In terms of clinicopathological variables, only tumor grade was associated with the expression of all biomarkers others exhibited different correlations in serous ovarian cancers. The expressions of HER-2/neu (c-erbB2), survivin and cycline D1 are positively correlated with the malignant potential of serous ovarian neoplasms.

RESUMO

To evaluate the matrix metalloproteinase-1 (MMP-1) expression in different parts of pelvic connective tissue in postmenopausal women with and without pelvic organ prolapse (POP). Ninety-one samples were obtained from only postmenopausal women (42 with POP and 49 non-POP subjects). All women were evaluated by pelvic organ prolapse quantitation. The POP group had stage 2 or more, and the controls had stage 1 or less. Round ligament (RL) and uterosacral ligament (USL) biopsies were obtained from women with POP and controls. Immunohistochemistry for MMP-1 was performed on formalin-fixed and paraffin-embedded sections. The two groups were matched for age, body mass index, parity and postmenopausal status. MedCalc Statistical Software Programme Version 12.0.5 was used for statistical analysis. Expression of MMP-1 were significantly higher in both RL and USL tissue from postmenopausal women with POP, compared with controls. MMP-1 immunoreactivities were identified in both RL and USL biopsies from all women with and without POP. The expression pattern of MMP-1 were similar in these ligaments and were significantly higher in POP group compared with control subjects. These changes indicate a possible relation between MMP-1 expression of RL and USL in women with and without POP.
