RESUMO
BACKGROUND/AIMS: A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) enzymes take part in extracellular matrix (ECM) remodeling which has been shown to contribute to the ovulation and follicular functions. We aimed to compare serum levels of ADAMTS-19 in patients with different fertility situations. METHODS: A total of 86 women were enrolled to this cross sectional and case-control study. Four groups were constituted with respect to women's clinical and hormonal status: group 1, women with premature ovarian failure (POF; n = 21); group 2, women with natural menopause (n = 21); group 3, women with polycystic ovary syndrome (PCOS; n = 22); and group 4, healthy fertile controls. Serum ADAMTS-19 levels and individual characteristics were compared among groups. RESULTS: -ADAMTS-19 levels were found as 36.7 ± 10.2, 40.1 ± 12.6, 46.7 ± 16.1, and 51.0 ± 18.8 ng/mL in POF, fertile, natural menopause, and PCOS groups, respectively (p = 0.012). Especially, ADAMTS-19 levels in the PCOS group were significantly higher than the POF group, as found in dual comparisons (p = 0.010). CONCLUSIONS: ADAMTS-19 was found to be higher in PCOS patients than in POF patients. This work provides a novel vantage point for function of ECM within the ovary. ADAMTS-19 may have a potential for being an important marker of ovarian function and oocyte pool.

AIM: Owing to its mysterious etiology, pathogenesis of preeclampsia (PE) remains controversial. Here we aimed to compare the levels of an angiogenesis marker, split and hairy related protein-1 (SHARP1), in PE vs. normal pregnancy. METHODS: Thirty-one patients with early-onset PE (EOPE), 26 patients with late-onset PE (LOPE), and 33 patients as a control group were recruited for this study in a tertiary referral center in Ankara, Turkey. Maternal venous SHARP1 levels and individual characteristics of the three groups were compared. RESULTS: Age and body mass indices were similar among the three groups. SHARP1 levels in patients with PE (27.7±13.2 ng/mL) were significantly lower than in the control group (34.7±17 ng/mL) (P=0.006). Additionally, SHARP1 levels were significantly different among patients in EOPE, LOPE, and control groups (P=0.022). Birth weights and Apgar scores in patients in EOPE group were significantly lower than the other two groups and showed a gradual increase from the EOPE group to the LOPE and the control group. Binary logistic regression method demonstrated that maternal venous SHARP1 level was a risk factor for PE. CONCLUSIONS: Maternal venous SHARP1 levels in PE are lower than a normal pregnancy. Its clinical applicability and role as a candidate for making sense of the distinctive pathogenesis of the EOPE and LOPE remain to be elucidated.

Fetal lymphangioma is a hamartomatous congenital anomaly of the lymphatic system, which is embracing the fetal skin (sometimes mucous membranes) and the subcutaneous tissue. The general consensus is that it occurs as a result of failure in lymphatic drainage. A 36-year-old pregnant woman was referred to our perinatology clinic at 22 weeks' gestation, because of a fetal right-sided axillary mass revealed by ultrasonography. The mass measuring 5x7x7cm in three dimensions had a multilocular structure without colour Doppler flow and well-circumscribed borders. Amniocentesis revealed a normal constitutional karyotyping. Lymphangioma was considered as prediagnosis. A healthy female baby weighing 3470 grams was delivered at term. Neonatal examination and the postnatal MRI confirmed the diagnosis. The baby is still on follow-up with the medical treatment of Sirolimus an anti-proliferative drug, and the mass got smaller significantly in 8 months after delivery.
RESUMO
BACKGROUND: Striae gravidarum (SG), commonly called stretch marks, is an important cosmetic problem which is not treatable, although preventive measures might be effective. The aim of this study was to determine individual risk factors causing SG and the degree to which preventive measures could be effective. METHODS: This prospective observational study included 211 singleton primiparous pregnant women who were hospitalized for birth and who did not have systemic diseases or other risk factors, like drug use or polyhydramnios. Patients were examined and divided into two groups with respect to whether or not they had striae. Individual features were compared between the two groups. RESULTS: While 159 patients (75.4%) had SG, 52 (24.6%) did not. Patients with striae had a significantly lower mean age and higher mean preconceptional body mass indices than ones without striae (p < 0.001 and p = 0.001, respectively). Family history (p = 0.002), having a male baby (p = 0.042), and lower educational level (p = 0.033) were also statistically significant in predicting striae. Use of preventive oil or drugs, smoking status, skin type, water intake, and level of financial income did not significantly predict SG. CONCLUSION: Informing women preconceptionally on the importance of modifiable risk factors, such as body weight and maternal age before pregnancy, can be useful, considering that stretch marks are carried for a lifetime and there is no conclusive treatment.

PURPOSE: Polycystic ovary syndrome (PCOS) is an important disease that may alter metabolic balances of the whole body. Progranulin is a growth factor which is related to epithelial, neuronal growth and oogenesis. Here, we aimed to investigate the diagnostic value of the levels of Progranulin in the clinical setting of PCOS, and its metabolic effects. METHODS: Forty-one adolescents and young women with PCOS and 39 age and body mass index matched adolescents and young women as a control group who attended to the youth center of a tertiary referral center were included in this cross-sectional case-control study. Progranulin levels, indices of insulin sensitivity, lipidemic markers, metabolic syndrome (MetS) criteria were compared between the groups. RESULTS: Progranulin levels in patients with PCOS (7.48 ± 1.93 ng/mL) were significantly higher than in the control group (6.25 ± 1.98 ng/mL) (p = 0.006). Luteinizing hormone (LH) levels, LH/Follicle stimulating hormone (FSH) ratios, free testosterone, dehydroepiandrosterone sulfate (DHEAS), C-reactive protein (CRP) levels in patients with PCOS were significantly higher than in the control group (p < 0.05, for all). The MetS was present in 8 (19.5 %) of the patients in the study group and in 1 (2.3 %) of the patients in the control group (p = 0.029). There was significant inverse correlation between high-density lipoprotein cholesterol (HDL-C) and progranulin levels of patients diagnosed with PCOS (p = 0.008). CONCLUSIONS: Progranulin may be a novel biomarker for cardiovascular risk in patients with PCOS, thus these cases should be directed to close follow-up for possible cardiovascular diseases. Future larger studies should focus on this entity.

Abstract Purpose The amniotic fluid volume (AFV) is known as a predictor for the wellness of a fetus. We aimed to investigate whether N-terminal pro-brain natriuretic peptide (NTproBNP) levels reflect AFV abnormalities in otherwise normal fetuses. Methods We recruited 24 women with isolated oligohydramnios, 23 women with isolated polyhydramnios, and 36 women with normal AFV at a tertiary referral center. NT-proBNP levels in umbilical venous samples and the individual characteristics of the three groups were compared. One-way ANOVA and Kruskal-Wallis analysis of variance were used for multi-group comparisons of continuous variables. When a significant difference was detected, the Scheffe test was performed as a post-hoc analysis. Proportions were compared using the Chi-square (2) test. Results Maternal age, body mass indices, weight gained in pregnancy and NT-proBNP levels were similar among the three groups. Apgar scores at 1 and 5 minutes significantly correlated with NT-proBNP levels in all newborns (Spearman's r = 0.23 ; p = 0.03 and Spearman's r = 0.24; p = 0.02, respectively). The umbilical venous NTproBNP levels did not differ between newborns who needed mechanical ventilation and those who didn't (p = 0.595). Conclusions NT-proBNP is a biomolecule that may provide insights into the pathogenesis of fetal circulatory problems and subsequent renal failure. Further investigations are warranted.
Resumo Objetivo Investigar se os níveis de peptídeo natriurético pró-cerebral N-terminal (NTproBNP) refletem anormalidades no volume de líquido amniótico (VLA) em fetos normais. Métodos Reunimos 24 mulheres com oligoidrâmnios isolados, 23 com poli-hidrâmnios isolados, e 36 com VLA normal em um centro de referência. Comparamos os níveis de NT-proBNP em amostras venosas umbilicais e características individuais em três grupos. Usamos análise de variância simples (One-way ANOVA) e a análise de variação Kruskal-Wallis para comparação de variáveis contínuas em múltiplos grupos. Quando identificada uma diferença significativa, o teste de Scheffe foi aplicado como uma análise post-hoc. Comparamos proporções usando o teste Qui-quadrado (2). Resultados Idade fértil, índice de massa corporal, ganho de peso na gestação e níveis de NT-proBNP foram similares nos três grupos. Apgar em 1 e 5 minutos correlacionaram significativamente com os níveis de NT-proBNP em todos os recém-nascidos (Spearman's r = 0,23; p = 0,03 e Spearman's r = 0,24; p = 0,02, respectivamente). Os níves de NT-proBNP venoso umbilical não se distinguiram entre os recém-nascidos que precisaram de ventilação mecânica e aqueles que não precisaram (p = 0,595). Conclusões NT-proBNP é um candidato biomolecular que pode contribuir na patogênese de problemas circulatórios fetais e subsequente insuficiência renal. São necessárias futuras investigações.

OBJECTIVES: TNF-related apoptosis-inducing ligand receptor-2 (TRAIL-R2) is produced both by decidual and trophoblast cells during pregnancy and known to participate in apoptosis. In this study, we aimed to determine and to compare maternal serum and placental TRAIL-R2 levels in patients with placenta accreta, non-adherent placenta previa and in healthy pregnancies. We also aimed to analyze the association of placenta accreta with the occurrence of previous C-sections. STUDY DESIGN: A total of 82 pregnant women were enrolled in this case-control study (27 placenta accreta patients, 26 non-adherent placenta previa patients and 29 age-, and BMI-matched healthy, uncomplicated pregnant controls). TRAIL-R2 levels were studied in both maternal serum and placental tissue homogenates. Determining the best predictor(s) which discriminate placenta accreta was analyzed by multiple logistic regression analyses. Adjusted odds ratios and 95% confidence intervals were also calculated. RESULTS: Both placental and serum TRAIL-R2 levels were significantly lower in placenta accreta group (median 34.82 pg/mg and 19.85 pg/mL, respectively) when compared with both non-adherent placenta previa (median 39.24 pg/mg and 25.99 pg/mL, respectively) and the control groups (median 41.62 pg/mg and 25.87 pg/mL, respectively) (p < 0.05). Placental TRAIL-R2 levels and previous cesarean section were found to be significantly associated with placenta accreta (OR: 0.934 95% CI 0.883-0.987, p = 0.016 and OR:7.725 95% CI: 2.717-21.965, p < 0.001, respectively). Placental and serum TRAIL-R2 levels were positively correlated. CONCLUSION: Decreased levels of placental TRAIL-R2 and previous history of cesarean section were found to be significantly associated with placenta accreta, suggesting a possible role of apoptosis in abnormal trophoblast invasion.

OBJECTIVE: This study aimed to evaluate the effect of obesity on surgical outcomes in patients who underwent gynecologic surgery. MATERIALS AND METHODS: In total, we evaluated 132 patients who underwent total abdominal hysterectomy with or without salpingo-oophorectomy for benign gynecologic procedures at our tertiary referral gynaecology clinic. RESULTS: The non-morbid obese group [body mass index (BMI) <40 kg/m2] included 94 patients, and the morbid obese group (BMI ≥40 kg/m2) included 38 patients. The perioperative outcomes of the groups were compared. The mean operative time was significantly longer for morbid obese patients than non-morbid obese patients (p<0.05). Estimated blood loss, the need for blood transfusion, postoperative hemoglobin values, and the need for an intraabdominal drain were similar between the groups. Early and late postoperative complications were significantly more frequent in the morbid obese group than the other group (p<0.05, for each). Early postoperative complications in patients who underwent vertical skin incision were significantly more frequent than in patients who underwent pfannenstiel incision (p<0.05). Late complications were comparable between the two types of skin incision. CONCLUSION: Morbid obesity significantly increases the mean operative times and the postoperative complication rates of abdominal hysterectomy operations.
RESUMO
OBJECTIVE: We aimed to evaluate the relationship between placental calcification and maternal and cord blood 25-hydroxyvitamin-D3 [25(OH)D] and calcium concentrations in low-risk obstetric population at term and their consequences. METHODS: Sixty non-complicated pregnant women at term admitted to maternity clinic were included in this prospective case-control study and classified into one of two groups according to grade of placental calcification by defined the Grannum classification: Group 1 (n=30), with Grade 3 placenta and Group 2 (n=30), the control group, no placental calcification noted. Baseline characteristics, maternal serum and umbilical cord 25(OH)D and calcium levels were compared between groups. RESULTS: The mean age of subjects was 26.4 ± 5.7 years. The mean serum 25(OH)D concentration of women (n=60) was 9.3 ± 3.4 (range 5.59-15.48) ng/mL. The prevalence of vitamin D deficiency [25(OH)D <20 ng/mL] was 100%. Maternal serum and cord blood calcium levels were significantly higher in Group 1 (p=0.036; p=0.037, respectively). In Group 2, maternal serum and cord blood 25(OH)D levels were higher than Group 1 (11.35 ± 6.54 and 10.22 ± 3.59 versus 9.6 ± 4.2 and 9.07 ± 2.43 ng/mL); but the difference is not statistically significant. CONCLUSIONS: Higher maternal calcium and lower 25(OH)D levels detected in patients with Grade 3 placental calcification indicated the importance of placenta on vitamin D regulation.

OBJECTIVE: With the prolongation of expected lifespan, premature ovarian failure (POF) has gained increased significance as a crucial female health problem. Here we aimed to investigate the diagnostic value of the levels of the growth factor Granulin, which has been associated with epithelial ovarian carcinoma, in the pathogenesis of POF. STUDY DESIGN: Thirty-one patients with POF and 57 patients as a control group were recruited for this study in a tertiary referral center in the capital of Turkey. Granulin levels and individual characteristics of the two groups were compared. RESULTS: Age and body mass indices were similar between the two groups. Granulin levels in patients with POF (2.94±1.91ng/mL) were significantly lower than in the control group (4.77±1.62ng/mL) (p<0.001). CONCLUSION: Future larger studies should focus on Granulin levels and its correlation with ovarian reserve markers, its clinical applicability, and its possible therapeutic value, thus providing further insight into the role of Granulin in the pathogenesis of POF.
