RESUMO

Background: Oncostatin M, a novel adipokine, plays a role in oogenesis, lipogenesis, and inflammation and may contribute to polycystic ovary syndrome pathogenesis and related metabolic problems. Adipokines are believed to contribute to developing polycystic ovary syndrome and its accompanying metabolic parameters, such as dyslipidemia, insulin resistance, and cardiovascular diseases. Methods: In this case-control study, the patients were grouped in a 1:1 ratio into either the polycystic ovary syndrome (n = 32) or the control group (n = 32). Serum levels of fasting glucose, insulin, C-reactive protein, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, white blood cell count, thyroid-stimulating hormone, luteinizing hormone, follicle-stimulating hormone, total testosterone, prolactin, estradiol, homeostasis model assessment of insulin resistance, and oncostatin M were analyzed. Results: Oncostatin M levels were significantly lower, but C-reactive protein levels were substantially higher in the polycystic ovary syndrome group than in the control group (p = 0.002, p = 0.001, respectively). Oncostatin M was inversely correlated with total cholesterol, non-high-density lipoprotein cholesterol, fasting glucose, and the luteinizing hormone/follicle-stimulating hormone ratio (ρ = -0.329, p =0.017; ρ = -0.386, p = 0.005; ρ = -0.440, p = 0.001; ρ = -0.316, p = 0.023, respectively). Conversely, there was no correlation between oncostatin M and total testosterone level (ρ = 0.220; p = 0.118). In the context of inflammation and metabolic parameters, oncostatin M was inversely correlated with C-reactive protein, homeostatic model assessment for insulin resistance score, and low-density lipoprotein cholesterol (ρ = -0.353, p = 0.019; ρ = -0.275, p = 0.048; ρ = -0.470, p < 0.001, respectively). Conclusions: Plasma oncostatin M levels were considerably lower in patients with polycystic ovary syndrome than in the control group, and this was inversely correlated with the hormonal and metabolic parameters of polycystic ovary syndrome. Thus, oncostatin M may be a novel therapeutic target for polycystic ovary syndrome and its metabolic parameters.

RESUMO

OBJECTIVE: The current study aimed to delineate the relationship between furin and chronic inflammation while cervical intraepithelial neoplasia progresses to cancer. STUDY DESIGN: This cross-sectional study included 81 women who required colposcopic examinations. The study groups were formed based on pathological results: Group I included women with cervical intraepithelial neoplasia (CIN) I (n = 30); Group II included women with CIN II-III (n = 28); and Group III included women with cervical cancer (CC) (n = 23). Furin, ki-67, and p16 levels were evaluated based on immunostaining intensity. The inflammatory indices were calculated in parallel with the literature from routine blood samples retrieved within one week before the procedure. RESULTS: Furin expression gradually increased from CIN I to CIN II-III and from CIN II-III to CC, respectively (p < 0.001, p = 0.005). NLR, MLR, PLR, and SII were significantly higher in the CC group (p < 0.001). ROC curve analysis unveiled that NLR, MLR, PLR, and SII predicted the presence of CC with a cutoff value of 2.39 for NLR (sensitivity: 91.3%, specificity: 63.8%, AUROC: 0.79, p < 0.001); a cutoff value of 0.27 for MLR (sensitivity: 78.3%, specificity: 72.4%, AUROC: 0.77, p = 0.009); a cutoff value of 123 for PLR (sensitivity: 100%, specificity: 41.4%, AUROC: 0.70, p = 0.04); and a cutoff value of 747 for SII (sensitivity: 69.6%, specificity: 90.7%, AUROC: 0.71, p = 0.014). CONCLUSION: Furin expression increased gradually in parallel with the severity of cervical intraepithelial neoplasia. The inflammatory indices were higher in the presence of CC and denoted a good discrimination ability for predicting cervical cancer.

RESUMO

Neutrophil gelatinase-associated lipocalin (NGAL, also known as lipocalin-2) is an acute-phase protein expressed in many tissues and plays a role in cell proliferation, regulation, and epithelial-mesenchymal transformation. Therefore, this study aimed to investigate serum NGAL levels and endometrioma tissue expression in women with endometriosis. This cross-sectional study was conducted at a university hospital. The endometrioma group included 36 women who underwent ovarian cystectomy for endometrioma, which was compared with a control group (n = 36) of women who underwent ovarian cystectomy due to benign persistent cysts (follicle cyst, theca lutein cyst, and serous cystadenoma). NGAL levels were analyzed using both serum enzyme-linked immunosorbent assay analysis and immunohistochemical tissue staining. Serum C-reactive protein and CA-125 levels were also evaluated. NGAL serum levels were significantly higher in the endometrioma group than in the control group (P < .05). C-reactive protein and CA-125 levels were also significantly higher in the endometrioma group (P < .05) and were correlated with NGAL levels. Immunohistochemical staining for NGAL was also higher in the endometrioma group (P < .001). NGAL may be considered a potential noninvasive biomarker of endometriosis.

RESUMO

BACKGROUND: We aimed to determine whether adding metformin to carboplatin treatment would reduce the damage to ovarian reserve associated with carboplatin use. METHODS: We included 35 adult female non-pregnant albino Wistar rats approximately three months old, weighing 220-310 g. The rats were divided into five groups of seven rats according to the treatment they received. Carboplatin and salin was given to Group 2, and carboplatin plus metformin was given to Group 3. Group 4 was administered only metformin. Group 5 was administered only salin. Carboplatin was given to Groups 2 and 3 as a single dose on the 15th day, while metformin was given to Groups 3 and 4 during the 28-day experiment. After oophorectomy, histopathologic analyses of primordial, primary, secondary, and tertiary Graff follicles according to the epithelial cells surrounding the oocyte and total follicular number were conducted per section. Serum Anti-Mullerian Hormone (AMH), tissue catalase, and malonyl dialdehyde levels were measured and compared within each group. RESULTS: The baseline and 15th-day serum AMH values of the menstrual cycle were compared among the groups, and no statistically significant differences were observed (p > 0.05). Group 3, which was given both carboplatin and metformin, had statistically significantly higher 28th-day AMH levels than Group 2, which was given only carboplatin and saline (p < 0.001). The number of primordial follicles in Group 3 was found to be statistically significantly higher than in Group 2 (p < 0.001). Tissue catalase enzyme levels in Group 3 were statistically significantly higher than in Group 2 (p < 0.001). Tissue malondialdehyde levels in Group 2 were statistically significantly higher than tissue malondialdehyde levels in Groups 3 and 4 (p < 0.001). CONCLUSIONS: Metformin may attenuate carboplatin-induced ovarian damage, possibly through its antioxidative effects.

RESUMO

To search whether or not the severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) messenger ribonucleic acid (mRNA) vaccine affects the fertility of women at the 6th months by using AMH, which is an ovarian reserve test. Our study, designed as a prospective case-control study, included 104 women who presented to the GOP EAH obstetrics and gynecology outpatient clinic in January and February 2022. The study group included 74 women who presented to the outpatient clinic and planned to be vaccinated and 30 women who refused to be vaccinated as the control group. Anti-COVID-19 antibody levels in all participants were checked before participation in the study, and participants who were positive were excluded from the study. Blood was taken from the participants in both control and study groups to evaluate their AMH levels before the 2 doses of vaccination. After 2 doses of the vaccine, they were called for follow-up, and serological tests were performed to check whether they were positive for anti-COVID-19 antibodies. Participants in both groups were referred for follow-up after 6 months, samples were taken again for AMH, and the data were recorded. The mean age of the study group was 27.6 ±â€…5.3 years, and the mean age of the control group was 28.65 ±â€…5.25 years (P = .298). There was no statistically significant difference between the vaccinated and nonvaccinated groups in terms of AMH levels measured at the 6th month (P = .970). When the vaccinated group was compared in terms of AMH values at the first visit before vaccination and at the 6th month after vaccination, no statistically significant difference was found between them (p:0.127) mRNA vaccination to protect against SARS-CoV-2 does not adversely affect ovarian reserve, which is an indirect indicator of fertility. mRNA vaccines continue to be the most important method of protection against epidemics. Carefully and accurately informing women who are hesitant to get vaccinated is of great importance for the success of the fight against the epidemic.

RESUMO

OBJECTIVES: This study investigated the discriminative value of serum telomerase levels in polycystic ovary syndrome (PCOS) and its relation to metabolic parameters. METHODS: Patients aged 16-23 years old who visited an adolescent outpatient clinic were included in the study. Our study consisted of 45 non-obese girls with polycystic ovary syndrome (PCOS), while our control group consisted of 45 healthy girls with normal menstrual cycles and no signs of hyperandrogenism. During the early follicular phase, all individuals were analyzed for serum telomerase levels, blood cell count, biochemical parameters, basal hormone levels, lipid profile and homeostatic model assessment of insulin resistance (HOMA-IR) index. RESULTS: Serum telomerase levels in PCOS patients were considerably lower (80.0 ± 52.8 IU/mL) than in the controls (113.1 ± 54.9 IU/mL) (p=0.004). We observed that blood telomerase levels less than 108.6 distinguished PCOS group from healthy controls with a sensitivity of 73.33% and a specificity of 57.78%. Low-density lipoprotein cholesterol, HOMA-IR index, Ferriman-Gallwey score and dehydroepiandrosterone sulfate values were higher in the study group. Moreover, serum telomerase levels were inversely correlated with body mass index (r=-0.339, p=0.023) and triglycerides (r=-0.511, p=0.002) in this group. Telomerase levels were also considerably lower in patients with metabolic syndrome (p=0.005). CONCLUSIONS: Serum telomerase activity is lower in PCOS patients than in healthy controls. Furthermore, decreased serum telomerase levels may correlate well with the metabolic complications of PCOS.

RESUMO

BACKGROUND: Ovulation is regulated by extracellular signal-regulated kinase-1 (ERK-1) and ERK-2 signaling mechanisms, and ERK-1/2 kinases modulates the function of most of the LH-regulated genes. Defective ERK kinase signaling that is secondary to a genetic problem contributes to both ovulatory dysfunction and metabolic problems in polycystic ovary syndrome (PCOS). We planned to investigate ERK-1 and ERK-2 gene polymorphisms in PCOS for the first time in the Turkish population. METHODS: One hundred two PCOS patients and 102 healthy controls were recruited for this patient control study. HOMA-IR, Ferriman-Gallwey score (FGS), waist-to-hip ratio (WHR), and body mass index (BMI) were assessed. Lipid profile levels, CRP, and total testosterone were determined. ERK-2 rs2276008 (G > C) and ERK-1 rs11865228 (G > A) SNPs were analyzed with a real-time PCR system. RESULTS: ERK-1 and ERK-2 genotypes were found to differ between the PCOS and control groups. In patients with PCOS, ERK-1 GA and ERK-2 GC genotypes were different in terms of BMI, FGS, HOMA-IR, CRP, total testosterone, and total cholesterol levels. CONCLUSIONS: ERK-1 and ERK-2 genes are involved in PCOS pathogenesis. BMI, FGS, HOMA-IR, and CRP levels are related to the heterozygote polymorphic types of ERK-1 and ERK-2 genes.

RESUMO

BACKGROUND: We aimed to investigate the levels of ADAMTS-1, which is secreted from the extracellular matrix during trophoblastic invasion in hyperemesis gravidarum (HEG). METHODS: In this cross-sectional study, we compared 45 HEG patients aged between 21 and 34 in terms of ADAMTS-1 levels with a control group consisting of 44 healthy pregnant women. The demographic characteristics and several laboratory parameters of the patients were recorded. Both groups were also compared in terms of ketonuria. We evaluated the correlation between ADAMTS-1 levels and ketonuria. RESULTS: The 2 groups were matched in terms of age, gestational age, gravidity, parity, and body mass index. Some inflammatory markers, such as neutrophil count, MPV, PDW, and PCT levels, were significantly higher in the HEG groups compared to the control group (all p < 0.05). However, mean MCV and serum TSH levels were statistically significantly lower in this group (both p < 0.001). ADAMTS-1 levels were 12.6 ± 1.4 ng/ml in the HEG group and 6.2 ± 1.6 ng/ml in the control group (p < 0.001). It was significantly and positively correlated with urine ketone, neutrophil count, and PDW, whereas negatively correlated with MCV and TSH value in the HEG group. ROC analysis showed that a threshold value of 11.275 ng/ml for ADAMTS-1 predicted HEG patients with a sensitivity of 60% and specificity of 95.5%. CONCLUSION: ADAMTS-1 serum levels are increased in HEG patients, and there is a positive correlation between ADAMTS-1 levels and ketonuria.

RESUMO

Polycystic ovary syndrome (PCOS) is a common, complex endocrine, and metabolic disorder. Inflammation has been thought to play an important role in PCOS pathogenesis in recent years, and various inflammatory markers have been investigated; however, no definite conclusion has been reached. As a multifunctional regulatory protein in different inflammatory processes, calprotectin may play a role in the etiology of PCOS. Therefore, based on this hypothesis, we aimed to determine serum calprotectin concentrations in women with PCOS and to compare them with healthy controls. This cross-sectional study was conducted at a tertiary referral center during the study period. Forty-three women (n = 43) with PCOS and 47 women (n = 47) in the control group were enrolled in this cross-sectional study. Serum calprotectin concentrations were measured using enzyme-linked immunosorbent assay and compared with markers of glucose and lipid metabolism. Clinical characteristics and hormonal parameters were evaluated in both groups. Levels of serum calprotectin were measured as 347 ±â€…28.8 and 188 ±â€…15.3 ng/mL in the PCOS and healthy control groups, respectively (P = .009). The mean homeostatic model assessment for insulin resistance[1] index and total testosterone levels were significantly higher in the PCOS group than in the control group (both P < .001). Spearman's correlation test demonstrated linear correlations between calprotectin and C-reactive protein, waist circumference, insulin resistance index, and total testosterone levels in the PCOS group (all P < .05). Serum calprotectin levels were higher in women with PCOS. This biomarker may be an indirect sign of insulin resistance, hyperandrogenism, or chronic inflammation in women with PCOS.

RESUMO

BACKGROUND: Polycystic ovary syndrome is known to be the most common hormonal disorder in women of reproductive age. Current evidence shows that regulatory proteins secreted from the adipose tissue called adipokines may have a role in polycystic ovary syndrome. We planned to investigate the role of endotrophin that has never been researched in polycystic ovary syndrome before and its correlation with other metabolic parameters and adipokines such as adiponectin and ghrelin in patients with polycystic ovary syndrome. METHODS: Forty-three women (n: 43) with polycystic ovary syndrome and 43 (n: 43) women as a control group were enrolled in this cross-sectional study. Serum levels of endotrophin, adiponectin, and ghrelin levels were measured with the enzyme-linked immunosorbent assay method. High-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol levels, luteinizing hormone/follicle-stimulating hormone ratio, total testosterone, and triglyceride levels were measured. Homeostasis model assessment for insulin resistance index, body mass index, Ferriman Gallwey Score, and waist-to-hip ratio were also evaluated. RESULTS: Total testosterone, homeostasis model assessment for insulin resistance, C-reactive protein, luteinizing hormone/follicle-stimulating hormone ratio, and triglyceride levels were higher in patients with polycystic ovary syndrome (p < 0.01). No difference was detected between the groups in terms of body mass index, Ferriman Gallwey Score, waist-to-hip ratio, total cholesterol, low-density lipoprotein, and high-density lipoprotein levels (p > 0.05). We did not observe any significant difference in adiponectin and ghrelin levels between the groups (p > 0.05). Patients with polycystic ovary syndrome had significantly higher endotrophin levels (p < 0.01). According to our regression analyses [area under the curve: 0.973 (0.935-1.000), 95% confidence interval, 95.2% sensitivity, and 100% specificity], it was shown that endotrophin greater than 92 ng/ml and homeostasis model assessment for insulin resistance greater than 2.5 might be good predictors for polycystic ovary syndrome diagnosis. CONCLUSION: We demonstrated that endotrophin level is higher in patients with polycystic ovary syndrome and may have predicted polycystic ovary syndrome with increased homeostasis model assessment for insulin resistance index. There was no significant difference in adiponectin and ghrelin levels in the polycystic ovary syndrome group. Endotrophin may have a role in polycystic ovary syndrome etiology rather than other adipokines.

RESUMO

INTRODUCTION: Studies investigating the relationship between sex hormones, inflammatory mediators and joint disorders have reported that sex hormones affect the pathogenesis of joint disorders. We aimed to investigate temporomandibular joint disorder (TJD) in polycystic ovary syndrome (PCOS) and the possible role of systemic mediators and sex hormones in TJD pathogenesis. MATERIAL AND METHODS: PCOS patients (n = 45) and controls (n = 30) aged 20-40 years, were enrolled in this case-control study. TJD diagnosis was performed by the specialist and blood samples were tested in the early follicular phase and on the 21 st (midluteal) day to investigate the levels of estrogen, progesterone, matrix metalloproteinase (MMP) 1-8-9, interleukin (IL)-1ß and Tumor necrosis factor (TNF)-α. RESULTS: TJD incidence was significantly higher in PCOS than the control group (51.1% and 6.9% respectively, p < 0.01). Midluteal progesterone (p < 0.01) was lower in PCOS group than the controls (p < 0.01). TNF-α (p < 0.01), MMP 1 (p < 0.01) and MMP 8 (p = 0.02) levels were found significantly higher in PCOS than the control group. Further, Progesterone levels were found significantly lower in TJD (+) PCOS patients than TJD (-) PCOS patients. However, significant difference was not found between the PCOS TJD (+) and PCOS TJD (-) patients for estrogen, MMP 1, MMP 8, MMP 9, TNF-α and IL-1ß. CONCLUSIONS: TJD frequency was found significantly increased in PCOS patients. Related with this, TJD co-occurrence should be kept in mind in the diagnosing and treatment process of PCOS due to hormonal alteration.

RESUMO

The chronic course of endometriosis suggests that the immune system may play a role in its aetiology. There may be resistance to cell lysis, as well as an immune defect underlying endometriosis. Granzyme B is a serine protease that is secreted by Natural Killer (NK) cells and cytotoxic T lymphocytes during a cellular immune response and can induce apoptosis. The aim of this study was to evaluate the relationship between both Granzyme B levels and Granzyme B gene polymorphisms in endometriosis patients. Women between the ages of 20 - 45 were included in the study. The patients were divided into two groups: those diagnosed with endometriosis and those who had not been diagnosed with endometriosis. In the blood samples, Granzyme B gene polymorphisms and serum levels of Granzyme B were studied. There was no difference between the groups in terms of median Granzyme B levels and the presence of AA, AG, and GG genotypes. There was a difference in median granzyme levels for the control group; the GG genotype was found at a lower frequency. The immune defect within endometriosis-related immune cells may not be exclusively due to Granzyme B. Other mediators that are secreted from immune cells may have additive effects.IMPACT STATEMENTWhat is already known on this subject? NK cells are cytotoxic and inhibit the implantation of autologous endometrial cells that are spilled into the peritoneum by retrograde menstruation. Thus, a reduction in NK cell activity may facilitate the progression of endometriosis. The literature review reveals that there are studies suggesting that NK cell activity may be insufficient in endometriosis. Granzyme B is a serine protease that is secreted by NK cells and cytotoxic T lymphocytes during a cellular immune response.What do the results of this study add? Granzyme B is one of the cytotoxic granules in NK and cytotoxic T lymphocyte cells and its genetic polymorphisms were tested in endometriosis. We found that median Granzyme B levels were significantly different in patients with the GG genotype in the control group, compared to those with the AA and AG genotype. However, this difference was not detected between the control and endometriosis groups.What are the implications of these findings for clinical practice and/or further research? Our results contribute to uncovering the pathogenesis of endometriosis since there are no previous studies in the literature regarding this topic. Although we did not find a difference, our results will inform further studies made on this topic. Studies with different molecules and an increased number of patients are needed. The immune defect of endometriosis may not be due exclusively to Granzyme B. Other mediators that are secreted from immune cells may have mutual effects and interactions.

RESUMO

Special hormonal and immunological changes are required for normal pregnancy continuation. To escape from rejection by the maternal immune system, pregnancy needs an optimum environment with the integration and the balance of immune factors. As an immunologically unique site that permits allogenic fetus to be tolerated by mother, the maternal-fetal interface has a vital role. Microorganisms may trigger innate immune responses at the maternal-fetal interface and this may have a significant impact on the success of pregnancy. While the presence of inflammatory markers are slightly increased in healthy pregnancies, their significant increase in preeclampsia suggests that the balance between the inflammatory and antiinflammatory mechanisms may be disrupted by a shift towards inflammation. Based on these immunological observations, we aimed to review the literature for the link between the inflammatory response and preeclampsia since its etiology has not yet been clarified.

RESUMO

OBJECTIVE: To determine whether there is a relationship between endometrium cancer and the oncoprotein cancerous inhibitor of protein phosphatase 2A (CIP2A). STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Balikesir University Medical Faculty Hospital, Balikesir, Turkey, from January 2013 to July 2018. METHODOLOGY: CIP2A was studied immunohistochemically and molecularly in paraffin blocks. The correlation between CIP2A expression and different endometrial pathologies were evaluated. In addition, the relationship between CIP2A expression in tumor tissue and clinicopathological prognostic parameters and also between Ki67, P53, HER2 with CIP2A expression were investigated. RESULTS: A higher expression of CIP2A was found in endometrium cancer tissues compared to normal endometrial tissues. In addition, CIP2A expression according to molecular and immunohistochemical results was associated with significant poor prognostic factors such as FIGO Stage, FIGO Grade, cervical involvement, myometrial invasion and HER2 positivity. CONCLUSION: CIP2A could be a promising and therapeutic target in endometrium cancer. Invention of the complex connections of CIP2A with other oncoproteins may lead to amazing and interesting developments in both early diagnosis and treatment. Key Words: CIP2A, Endometrium cancer, Expression, Oncoprotein.

RESUMO

OBJECTIVE: The aim of our study was to evaluate serum high-sensitivity C-Reactive Protein (hs-CRP), sialic acid (SA), and interleukin-6 (IL-6) levels in pregnancies complicated with preeclampsia (PE) and intrauterine growth restriction (IUGR) and to compare with healthy pregnancies. MATERIALS AND METHODS: This study was conducted at a tertiary-level maternity hospital with 80 pregnant women. Fasting blood samples were taken from 44 consecutive women with pregnancies complicated by PE (n: 20) and IUGR (n: 24), and 36 were from normal pregnancies. Serum hs-CRP, SA, and IL-6 concentrations were measured in all participants. RESULTS: Serum mean hs-CRP, SA, and IL-6 levels were higher in the PE and IUGR group when compared with the control group, but this difference was statistically insignificant (P>0.05). No significant correlation was observed between these inflammatory markers (P>0.05). CONCLUSION: The serum levels of hs-CRP, SA, and IL-6 were not elevated in pregnancies complicated with PE and IUGR compared with normal pregnancies. Since pregnancy is already a process with inflammation, fluctuations in some markers related to inflammation may be masked by the gestation itself. A local subclinical inflammation may have a role in the pathogenesis of PE and IUGR rather than systemic inflammation.

RESUMO

Introduction The aim of this study was to compare serum vitamin D and osteocalcin levels in non-osteoporotic postmenopausal women with and without metabolic syndrome and to analyze the relationship between serum vitamin D and osteocalcin levels and the relationships between these two factors and other clinical/biochemical parameters. Material and Method This cross-sectional study was carried out in 191 postmenopausal non-osteoporotic (T-score > - 2.5) women. Patients were divided into two groups according to the presence or absence of metabolic syndrome. Blood samples were obtained and evaluated for 25-hydroxyvitamin D, osteocalcin, insulin resistance (using a homeostatic model assessment of insulin resistance), glycosylated hemoglobin (HbA 1c ), calcium, phosphorus, deoxypyridinoline, thyroid-stimulating hormone, lipid profile, fasting insulin, fasting glucose and HbA 1c levels. Demographic and laboratory parameters were recorded for each woman. Results Vitamin D was found to be lower in women with metabolic syndrome compared to controls (16.1 ± 11.2 vs. 20.4 ± 13.1 mg/dL; p = 0.013). Similarly, osteocalcin was found to be significantly lower in the metabolic syndrome group compared to the control group (4.2 ± 2.1 vs. 5.5 ± 3.0; p < 0.001). A significant positive correlation was observed between vitamin D and osteocalcin levels (r = 0.198; p = 0.008). There was an inverse correlation between vitamin D and some of the lipid parameters. However, osteocalcin levels were negatively correlated with C-reactive protein, insulin resistance, and HbA 1c in both groups (p = 0.003, p = 0.001 and p = 0.048, respectively). Conclusion Vitamin D deficiency is common in postmenopausal women, even in women who are non-osteoporotic. Serum levels of vitamin D are significantly decreased in cases with metabolic syndrome. Vitamin D may directly improve serum lipid profiles and may indirectly decrease insulin resistance and subclinical systemic inflammation through the impact on the metabolic functions of osteocalcin.

RESUMO

We aimed to evaluate the effects of detorsion and Allium sativum (garlic oil) treatment on the ovarian reserve in an ovarian torsion model. Ovarian torsion may lead to loss of ovarian tissue and infertility. It is an experimental rat study that was carried out on 16 sets of ovaries each, one for treatment group and a control group. In the control group, the procedure involved only the surgically opening and closing the abdomen. Bilateral adnexal torsion/detorsion was performed after a 3-hour ischemia period for the detorsion-only group. The detorsion + Allium sativum group received a 5 ml/kg dose of Allium sativum intraperitoneally, 2 hours before surgery. After the second surgery, removed ovarian samples were evaluated for follicle counts, damage scores and other parameters. Primordial, preantral, small antral and large antral follicle counts were significantly higher in the detorsion + Allium sativum group. Degeneration, congestion, hemorrhage ,inflammation and total damage scores were significantly elevated in the detorsion only group compared to those for the detorsion + Allium sativum group. Finally, there was a significant correlation between AMH alterations and postoperative, preantral follicle count (p<0.05). As a conclusion detorsion + Allium sativum treatment may be effective in protecting the ovarian reserve after torsion.


Intentamos evaluar los efectos de la detorsión y el tratamiento con Allium sativum (aceite de ajo) en la reserva ovárica en un modelo de torsión ovárica. La torsión ovárica puede ocasionar pérdida de tejido ovárico e infertilidad. Este es un estudio experimental en ratas que se llevó a cabo en 16 sets de ovarios para cada grupo: tratamiento y control. En el grupo control, el procedimiento involucró solamente la apertura y el cierre quirúrgicos del abdomen. La torsión / detorsión anexial bilateral se realizó después de un período de isquemia de 3 horas para el grupo de solo detorsión. El grupo de detorsión + Allium sativum recibió una dosis de 5 ml / kg de Allium sativum por vía intraperitoneal, 2 horas antes de la cirugía. Después de la segunda cirugía, las muestras ováricas eliminadas se evaluaron para recuentos de folículos, puntajes de daño y otros parámetros. Los recuentos de folículos antrales primordiales, preantrales, antrales pequeños y grandes fueron significativamente mayores en el grupo con detorsión + Allium sativum. Los puntajes de degeneración, congestión, hemorragia, inflamación y daño total fueron significativamente elevados en el grupo de solo detorsión, en comparación con los del grupo de detorsión + Allium sativum. Finalmente, hubo una correlación significativa entre las alteraciones de AMH y el recuento de folículos preantrales postoperatorios (p <0,05). Como conclusión, el tratamiento con detorsión + Allium sativum puede ser eficaz para proteger la reserva ovárica después de la torsión.

RESUMO

AIM: Postoperative pelvic adhesions are significant health care problems causing chronic pelvic pain, infertility and intestinal obstruction after abdominal or pelvic surgery. We investigated the effects of quercetin and Surgicel for the prevention of adhesions after gynecological surgery. METHODS: A double blind, randomized, controlled experimental study was designed. Forty female Wistar Hannover rats were divided into five groups: control, sham operated, quercetin, Surgicel, and quercetin + Surgicel. The control group received medication used for the surgical procedure only. The sham group received a laparotomy only. The quercetin group received 15 mg/kg quercetin in addition to undergoing the standard surgical procedure, and the injuries in the surgical group were covered with a single, 1 cm2 layer of Surgicel (oxidized regenerated cellulose). The quercetin + Surgicel group received both 15 mg/kg quercetin and a single, 1 cm2 layer of Surgicel. Adhesions were scored 14 days after the first surgical procedure. RESULTS: The extent, severity, degree, total adhesion, inflammation and fibrosis scores of the control group were significantly higher than those of the quercetin, Surgicel, and quercetin + Surgicel groups. There was no significant difference between the Surgicel and quercetin groups in degree, but all other parameters were significantly higher in the Surgicel than in the quercetin group. The quercetin + Surgicel group had lower adhesion scores than the quercetin group. CONCLUSIONS: Quercetin, Surgicel and quercetin + Surgicel treatment may be useful for preventing pelvic adhesions.

RESUMO

OBJECTIVE: To evaluate the effect of obesity on clinical parameters and pregnancy rates in infertile women with polycystic ovary syndrome (PCOS), who have undergone ovulation induction. STUDY DESIGN: This retrospective study included 177 women with PCOS who presented to our gynecological endocrinology outpatient clinic for diagnosed infertility. All of the patients initially received clomiphene citrate (CC), and if CC resistance was noted, gonadotropins were used. The patients were classified into 2 groups according to BMI (<30 kg/m2=control group and ≥30 kg/m2=study group). Pregnancy was assessed by ß-hCG levels and a visible gestational sac in the endometrium. RESULTS: The demographic and hormonal parameters were similar between the groups. The mean duration of infertility was longer in the study group (p<0.05). In the study group, cycle cancellation due to CC resistance (p=0.039) and mean baseline LH levels (p=0.026) was statistically more likely than in the control group. On follow-up, 4 (9.3%) patients in the study group had conceived and 26 (19.4%) patients in the control group had conceived (p=0.041). CONCLUSION: Obesity adversely affects pregnancy rates in women with PCOS who undergo ovulation induction cycles. Clinicians should recommend weight loss in these patients before ovulation induction.

RESUMO

BACKGROUND: Prediction of preeclampsia and adverse maternal and perinatal outcomes with biomarkers has been proposed previously. Anti-mullerian hormone (AMH) is a growth factor, which is primarily responsible of the regression of the mullerian duct, but also used to predict ovarian reserve and decreases with age similar to the fertility. AIM: To evaluate the predictive role of maternal anti-mullerian hormone (mAMH) in adverse maternal and perinatal outcomes in preeclampsia. METHODS: This prospective case-control study was conducted at current high-risk pregnancy department in a tertiary research hospital and 45 cases with preeclampsia classified as study group and 42 as control group. Data collected and evaluated were; age, body mass index (BMI), marriage duration (MD), gestational weeks (GW), gravidity, parity, mode of delivery, birth weight, newborn Apgar score, newborn gender, maternal complication, perinatal outcome, some laboratory parameters and mAMH. The association between mAMH levels and maternal and fetal outcomes were evaluated. RESULTS: There were no statistically significant differences between groups in terms of age, BMI, MD, gravidity, parity and newborn gender (p > 0.05). GW, vaginal delivery, birth weight, newborn Apgar score, were statistically significantly lower in preeclamptic patients when compared with non-preeclamptic patients (p < 0.001). Adverse maternal and perinatal outcomes were statistically significantly higher in the study group (p < 0.001). The laboratory values [alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN), creatinine, lactic dehydrogenase (LDH), uric acid and fibrinogen) were statistically significantly lower in the control group (p < 0.001). The mAMH level was significantly lower in the preeclamptic group (p: 0.035). There was no correlation between mAMH levels and demographic and clinical parameters. The area under the ROC curve (AUC) was 0.590 and the cut-off value was 0.365 ng/ml with sensitivity of 67.4% and specificity of 47.1% for mAMH. Logistic regression analysis showed a statistically insignificance between mAMH and maternal complication and perinatal outcome (p: 0.149). CONCLUSION: According to this study, mAMH level was lower in preeclamptic patients than in normal pregnants, and is found to be a discriminative factor with low sensitivity and specificity. There was no relationship between mAMH and adverse maternal and perinatal outcomes. Further randomized controlled studies with more participants are needed to evaluate the accurate effects of mAMH levels on preeclampsia and should increase the power of mAMH levels in predicting the preeclampsia.
