ABSTRACT
OBJECTIVE: The aim of this study was to investigate the relationship between Chitinase 3-Like 1 gene polymorphisms and the occurrence of preeclampsia in a selected cohort of pregnant women. METHODS: A total of 75 pregnant women participated in the study, 35 of whom were diagnosed with preeclampsia, while 40 served as healthy controls. The preeclamptic group was subdivided based on severity. Real-time polymerase chain reaction was employed to analyze the serum samples for variations in Chitinase 3-Like 1 gene polymorphisms. RESULTS: The rs880633 polymorphism was found to be significantly more frequent in the control group (80%) compared with the overall preeclamptic group (60%) (p<0.05). In the severity-based subgroups, rs880633 appeared in 57.1% of non-severe and 61.9% of severe preeclamptics. Contrarily, the heterozygous form of rs7515776 polymorphism showed a significantly higher prevalence in the preeclamptic cohort (p<0.05), without distinctions in severity subgroups. CONCLUSION: The study suggests that the rs880633 polymorphism may serve a protective role against the development of preeclampsia, whereas the rs7515776 polymorphism may be associated with an elevated risk. Further research is warranted to elucidate the clinical implications of these findings.

Objective This study aimed to investigate follicle-stimulating hormone receptor (FSHR) polymorphisms (Thr307Ala and Asn680Ser), estrogen receptor 1 (ESR1) polymorphisms (PvuII and XbaI), and ESR2 polymorphisms (RsaI and AluI) in Turkish women with follicle-stimulating hormone (FSH) and anti-Mullerian hormone (AMH) discordance. Method Genotyping was performed in 60 patients aged 21-35 with FSH-AMH discordance and/or low ovarian reserve and 20 age-matched controls with normal FSH and AMH levels. The patients were investigated in four groups of 20 women according to their FSH and AMH levels. Groups 1, 2, 3, and 4 were as follows: normal FSH and low AMH levels, normal AMH and high FSH levels, high FSH and low AMH levels, and normal FSH and AMH levels. Genomic DNA was obtained from 3 cc peripheral blood, and polymorphisms were analyzed using TaqMan genotyping assays. Relations between groups of categorical variables were analyzed with a chi-square test. Differences between the groups were assessed using a student's t-test or Mann-Whitney U test. Results Women with discordant FSH and AMH levels (group 1 and group 2) were not statistically different from women with concordant FSH and AMH levels (group 3 and group 4) in terms of FSHR, ESR1, and ER2 single nucleotide polymorphisms (SNPs). Body mass index (BMI) was statistically significant between groups 1 and 2 as well as groups 2 and 3 (p = 0.004). Conclusions This study showed that FSHR, ESR1, and ESR2 SNPs have not had any effect on AMH-FSH discordance in reproductive age Turkish women.
ABSTRACT
MicroRNA is associated with angiogenesis, invasion, proliferation, and vascular endothelial remodeling of various diseases. We aimed to investigate serum MicroRNA (miRNA) levels in preeclampsia (PE) and to determine whether any changes in miRNA levels are useful in predicting early onset preeclampsia (EOPE) and adverse perinatal outcomes. A total of 89 pregnant patients were enrolled in this prospective case-control study (55 PE and 34 healthy controls). miR-17, miR-20a, miR-20b, miR126, miR155, miR-200, miR-222, and miR-210 levels were studied in maternal serum in preeclamptic pregnant women. Multiple logistic regression analyses analyzed the risk factors which are associated with EOPE and adverse maternal outcomes. The Real-time RT-PCR method was used to determine maternal serum miRNA levels. Serum miR-17, miR-20a, miR-20b, miR126, and miR-210 levels were significantly higher in PE than the control group (p < .001, p < .001, p < .001, p < .001 and p = .047 respectively). Increased miR-17, miR-20a, and miR-20b levels were independently associated with PE (OR: 0.642, 95%Cl: 0.486-0.846, p = .002; OR: 0.899, 95%Cl: 0.811-0.996, p = .042 and OR: 0.817, 95%Cl: 0.689-0.970, p = .021). Increased miR-17 and miR-126 levels were negatively correlated with serum EOPE in PE (r = -.313, p = .020), and increased miR-210 levels were significantly positively correlated with EOPE in PE (r = .285, p = .005). Increased expression of serum miR-17, miR-20a, miR-20b, miR126, and miR-210 were found to be associated with PE, also increased expression of miR-17, miR-20a, and miR-20b were to be predicted with PE, also increased maternal serum miR-17 and miR-126 expressions were negatively correlated and increased miR-210 expression was positively correlated with EOPE in PE women.

ABSTRACT
Background Polycystic ovary syndrome (PCOS) is recognized as one of the most common endocrine pathologies in females of reproductive age worldwide. This study investigated the relationship between serum sclerostin levels and body mass index (BMI) in women with PCOS. Methods Women aged 18-40 years who presented to our clinic between January 1, 2019, and January 1, 2020, and were diagnosed with PCOS were included in this study. The patients' clinical and laboratory data were recorded, and waist circumference, hip circumference, and BMI values were calculated. The patients with a BMI of >25 kg/m2 were evaluated as Group I, those with a BMI of <18.5 kg/m2 as Group II, and those with a BMI of 18.5-25 kg/m2 as Group III. Serum sclerostin levels were compared between the BMI groups. Results The study included 90 patients. The mean BMI values were 32.2±2.1, 17.0±0.9, and 22.9±2.1 kg/m2 for Groups I, II, and III, respectively. We detected a statistically significant difference in serum sclerostin levels between Group II and Group I (p<0.005). There was a significant, positive correlation between the sclerostin level and BMI (r=0.258, p=0.014), weight (r=0.237, p=0.044), waist measurement (r=0.225, p=0.045), and hip measurement (r=0.225, p=0.033). Conclusion This study revealed that abnormal body composition in PCOS could alter circulating sclerostin levels.
ABSTRACT
PURPOSE: To investigate the correlation between fetal clavicle length and gestational age in pregnant patients from 14 and 27 weeks of gestation. METHODS: This was a retrospective cross-sectional study of patients from 14 and 27 weeks of gestation. Ultrasonographic measurements such as abdominal circumference (AC), femur length (FL), humerus length (HL), clavicle length (CL), head circumference (HC), biparietal diameter (BPD), estimated fetal weight (EFW), and transverse cerebellum diameter (TCD) were made and compared. RESULTS: A total of 552 patients were evaluated in our clinic and CL was measured properly and successfully in all fetuses. Fetal AC, FL, HL, CL, BPD, HC, EFW and TCD measurements were significantly and strongly correlated with gestational week, and Pearson's correlation values were 0.964, 0.965, 0.959, 0.965, 0.951, 0.917, 0.925, and 0.954, respectively (p < 0.001). In the regression analysis equation, gestational week = 0.894 + CL × 0.961. CONCLUSION: There was a significant positive correlation between fetal CL (mm) and gestational week. We suggest that the 1 mm = 1 week rule can be used for patients with anomalies of the cerebellum and vermis, as well as for patients with unknown last menstrual period.
ABSTRACT
OBJECTIVES: To understand the effect of 50-g oral glucose tolerance test (OGTT) on fetal celiac artery and superior mesenteric artery (SMA) Doppler parameters. METHODS: A total of 43 healthy pregnant women followed in our hospital were included in the study. All Doppler parameters of the celiac artery and SMA (peak systolic velocity (PSV); pulsatility index (PI); resistance index (RI); systolic/diastolic ratio (SD); time average maximum velocity (TAMAX)) were obtained by ultrasonography before and 1â¯h after OGTT. RESULTS: The mean PSV value of the celiac artery decreased statistically significantly after OGTT (37.29 ± 11.96â¯cm/s; 29.51 ± 10.07â¯cm/s; p=0.002). While the mean of the PI was 2.09 ± 0.57 before the test, it was found to be 1.84 ± 0.64 after the test (p=0.027). Mean PSV (39.82 ± 13.07â¯cm/s; 35.19 ± 15.27â¯cm/s; p=0.104) and PI (2.21 ± 0.65; 2.11 ± 0.80; p=0.375) values of SMA were also found to be decreased without statistically significancy. CONCLUSIONS: The data obtained from our study reveals that the PSV and PI values of celiac artery and SMA slightly decrease after OGTT.

BACKGROUND: The aim of this study is to investigate the effect of trimethylamine (TMA) and trimethylamine-n-oxide (TMAO) on the contractility of human umbilical artery and the possible mechanisms involved. METHODS: Vasoactive responses to TMA and TMAO on human umbilical artery rings were measured in isolated organ baths. Cumulative dose-response curves for TMA and TMAO were obtained before and after incubation with atropine, yohimbine, prazosin, indomethacin, verapamil, and Ca+2 -free Krebs-Henselite solution. RESULTS: Administration of cumulative TMA and TMAO resulted in dose-dependent contraction at concentrations ranging from 10 to 100 mM on human umbilical artery rings. TMA-induced contractions were more potent than TMAO-induced contractions (TMA: -logEC50 = 1.00 ± 0.02, TMAO: -logEC50 = 0.57 ± 0.02). Contraction responses to TMA were significantly lower in the presence of verapamil and in the absence of external Ca+2 (p < 0.001, p < 0.05, respectively). CONCLUSION: Our results showed that TMA and TMAO caused vasoconstriction in isolated human umbilical artery rings. Our findings also indicated that TMA but not TMAO-induced vasoconstriction was partially dependent on extracellular Ca2+ and calcium influx through L-type Ca2+ channels. Our results suggest that TMA and TMAO may have the potential to contribute to cardiovascular diseases through their direct effect on vascular contractility in human arteries.

OBJECTIVES: As a result of the integration of molecular changes into the histological classification of cancers, which increases diagnostic repeatability, the differences between the groups become more prominent and targeted therapies gain significance. The most comprehensive molecular study regarding endometrial carcinomas (EC) is The Cancer Genome Atlas (TCGA) project. According to TCGA, endometrial carcinomas are classified into four molecular prognostic subgroups: copy-number-low/p53-wild-type (p53wt), DNA polymerase epsilon (POLE)-mutated/ultramutated (POLEmt), microsatellite-instability/hypermutated (MSI), and copy-number-high/p53-mutated (p53mt). In this study, we aim to apply the molecular classification to our high-grade endometrial cancer patients, and particularly, to identify our overtreated patients. MATERIAL AND METHODS: Ninety-seven patients diagnosed with high-grade EC in Selcuk University, Faculty of Medicine between 2009-2018 were retrospectively evaluated and classified into four subgroups. Primary outcomes of overall and progression-free survival were evaluated for clinical, pathological, and molecular features. Further, all molecular groups were divided into endometroid and non-endometrioid groups, and disease-free survival (DFS) and overall survival (OS) were investigated across groups. RESULTS: According to molecular classification, 23 patients (23.7%) were assigned to the MSI group, 21 (21.6%) to the POLEmt group, 40 (41.2%) to the p53mt group, and 13 (13.4%) to the p53wt group. Patients' DFS (p = 0.001) and OS rates (p = 0.001) were significantly different according to their molecular classification. The results of our analyses determined that, in the molecular classification of high-grade ECs, the p53mt group had the poorest prognosis and the POLEmt group had the best prognosis. Tumor size, myometrial invasion, lymphovascular space invasion (LVSI), lymph node metastasis, cervical invasion, ovarian invasion and stage showed statistically significant differences based on molecular classification (p < 0.05). CONCLUSIONS: The use of molecular classification in the clinical practice will allow more accurate prognostic prediction and more appropriate treatment planning, particularly as high-grade ECs constitute a heterogenous group with poor prognosis.

The molecular pathways involved in the development of vulvar squamous cell carcinoma (SCC) cancer are not completely known. Nicotinamide N-methyltransferase (NNMT) is a cytosolic enzyme associated with tumorigenesis and metastasis in a variety of cancers. Its role in vulvar cancer has not been studied, previously. Vulvar SCC, high and low grade squamous intraepithelial lesions (SILs) and benign squamous hyperplasia were analysed immunohistochemically. The mean staining score for vulvar SCC was significantly higher than the score for vulvar squamous hyperplasia (p<.001). The mean relapse-free survival for patients with low and high NNMT expression was 41.4 months (95% CI: 25.6-57.2) and 19.8 months (95% CI: 3.0-36.6), respectively (p=.035). The mean disease-specific survival for patients with low and high NNMT expression was 75.8 months (95% CI: 57.5-94.2) and 27.8 months (95% CI 12.2-43.4), respectively (p=.015). Although quite preliminary, this study showed that NNMT expression was elevated in vulvar SCC compared to benign and premalignant lesions. Additionally, elevated NNMT expression was associated with poor survival. Impact StatementWhat is already known on this subject? Nicotinamide N-methyltransferase (NNMT) is a methyltransferase, associated with tumour progression, spread and poor prognosis in a variety of cancers. Its upregulation can lead to DNA hypomethylation, which can in turn result in the activation of proto-oncogenes and deactivation of tumour suppressor genes.What do the results of this study add? Although quite preliminary, this study showed that NNMT expression was elevated in vulvar SCC compared to benign and premalignant lesions. Additionally, elevated NNMT expression was associated with poor survival.What are the implications of these findings for clinical practice and/or further research? NNMT has been regarded as a potential target of cancer therapy and its role in vulvar cancer has not been studied, previously. This is the first study to investigate the expression of NNMT in vulvar cancer and associate NNMT elevation with poor survival. NNMT can further be investigated as a possible target of vulvar cancer therapy.

The aim of the current study was to estimate the incidence of unexpected leiomyosarcoma (LMS) in patients who underwent surgery due to leiomyomas in Konya province, and to contribute to the literature discussing comparisons with similar studies. The digital archives of eight high-volume hospitals were studied for surgeries performed due to leiomyomas between January 2012 and January 2019, and leiomyosarcoma incidence was calculated based on the data obtained. Twenty-one patients in 3703 cases were found to have unexpected leiomyosarcoma, which means we can expect one leiomyosarcoma in 176 (0.56%) surgeries. Six more malignant tumours were detected among the remaining cases. Thus, our study estimated the incidence of unexpected leiomyosarcoma as 1/176 (0.56%), which is higher than most of the studies in the literature justifying the debate started by the FDA in 2014. As the tumour biology is not yet clear, and the incidence of unexpected leiomyosarcoma tends to be so high, the key focus must be to try to detect uterine leiomyosarcomas preoperatively for robust patient care.IMPACT STATEMENTWhat is already known on this subject? The incidence of unexpected leiomyosarcoma varies widely from 1/498 to 1/8300 depending on the study method and the type of procedure, and there is still controversy, even after the FDA statement that led to a major restriction in laparoscopic surgeries due to concerns about inadvertent morcellation of leiomyosarcomas.What do the results of this study add? To the best of our knowledge, the current study found the highest incidence of unexpected leiomyosarcoma, and consequently a serious evaluation of all patients undergoing surgery due to leiomyomas preoperatively considering a leiomyosarcoma candidate is recommended.What are the implications of these findings for clinical practice and/or further research? Studies on tumour biology and novel markers must be supported for accurate preoperative diagnosis of leiomyosarcoma.

INTRODUCTION: This study aimed to evaluate the diagnostic accuracy of the sentinel lymph node (SLN) mapping algorithm in high-risk endometrial cancer patients. METHODS: Two hundred forty-four patients with non-endometrioid histology, grade 3 endometrioid tumors and/or tumors with deep myometrial invasion were enrolled in this retrospective, multicentric study. After removal of SLNs, all patients underwent pelvic ± paraaortic lymphadenectomy. Operations were performed via laparotomy, laparoscopy or robotic surgery. Indocyanine green (ICG) and methylene blue (MB) were used as tracers. SLN detection rate, sensitivity, negative predictive value (NPV) and false-negative rate (FNR) were calculated. RESULTS: Surgeries were performed via laparotomy in 132 (54.1%) patients and 152 (62.3%) underwent both bilateral pelvic and paraaortic lymphadenectomy. At least 1 SLN was detected in 222 (91%) patients. Fifty-five (22.5%) patients had lymphatic metastasis and 45 patients had at least 1 metastatic SLN. Lymphatic metastases were detected by side-specific lymphadenectomy in 8 patients and 2 patients had isolated paraaortic metastasis. Overall sensitivity, NPV and FNR of SLN biopsy were 81.8%, 95% and 18.2%, respectively. By applying SLN algorithm steps, sensitivity and NPV improved to 96.4% and 98.9%, respectively. For grade 3 tumors, sensitivity, NPV and FNR of the SLN algorithm were 97.1%, 98.9% and 2.9%. CONCLUSION: SLN algorithm had high diagnostic accuracy in high-risk endometrial cancer. All pelvic metastases were detected by the SLN algorithm and the isolated paraaortic metastasis rate was ignorable. But long-term survival studies are necessary before this approach becomes standard of care.

BACKGROUND: In this study, we investigated the effect of calcium and vitamin D (Ca/Vit D) supplementation on the clinical, hormonal, and metabolic profile of patients with low vitamin D levels. In addition, we investigated the effect of Ca/Vit D supplementation on asymmetric dimethylarginine (ADMA) level in patients with polycystic ovary syndrome (PCOS). METHODS: In total, 75 patients aged 19-35 years, with a normal body mass index and a diagnosis of PCOS and Vit D deficiency/insufficiency, were included in the study. Patients received 50,000 IU of vitamin D3 once a week for 8 weeks. Afterward, 2500 mg calcium carbonate equivalent to 1000 mg calcium ion and 9.68 mg cholecalciferol equivalent to 880 IU vitamin D3 were administered orally as a maintenance treatment once a day. RESULTS: The mean age of the patients was 21.7 ± 3.5. After Ca/Vit D supplementation, Vit D levels significantly increased compared to baseline (8.6 ng/ml) levels. An increase in SHBG levels (p < 0.001), a decrease in total testosterone, FAI (p = 0.042), and ADMA levels (p < 0.001) were observed in the first and third months compared to the onset. Significant improvement compared to baseline was observed in menstrual irregularity and median mFG score. CONCLUSION: Ca/Vit D supplementation can improve PCOS symptoms such as menstrual dysfunction, hirsutism, and hyperandrogenism. It may be effective in reducing the risk of cardiovascular disease in patients with PCOS later in life by decreasing ADMA levels, which is an indicator of endothelial dysfunction.

BACKGROUND: The aim was to investigate factors that predict when patients with previous cesarean section will undergo cesarean section (CS) using ultrasonography in the 37th gestational week. MATERIAL AND METHODS: In this prospective cross-sectional study, a total of 166 patients with previous CS who presented to the hospital for routine checks at the 370/7th gestational week were included in the study. Uterine-related, fetus-related, and patient-related factors that affect labor time were analyzed by the same physician at admission, and the patients were then divided into two groups as those having CS at early term (370/7 to 386/7 weeks of gestation) and full-term (390/7 to 406/7 weeks of gestation). Ninety-four patients underwent CS at full-term and 72 patients underwent CS at the early term in the study. RESULTS: There was no significant difference for age (years), parity, weight gain, previous cesarean number, cervical length, myometrial thickness, estimated fetal weight, and full lower uterine segment thickness between the groups (p>.05). In the full-term group, 58% had a history of vaginal birth, whereas, in the early-term group, 42% had a history of vaginal birth (p < .05). Vaginal birth history was found to be independently associated with reaching full-term (respectively, OR: 2.876, 95% CI: [1.227-6.738]; p = .015) in all patients. Two different regression models were created to predict different CS times after the 37th week of pregnancy. Weight gain was found to be independently associated with CS time within the first seven days after admission (OR: 1.267, 95% CI: [1.003-1.599]; p = .047). Vaginal birth history and estimated fetal weight were found to be independently associated with CS time in the 8th day and further after admission (OR: 0.244, 95% CI: [0.089-0.675]; p = .007 and OR: 1.002, 95% CI: [1.000-1.003]; p = .047). CONCLUSION: Vaginal birth history can be useful to predict reaching full-term in patients with previous CS. Determination of such risk factors is important in terms of reducing the frequency of emergency cesarean delivery.

This study presents the preparation of a novel tetra-substituted phthalonitrile (1), namely, 3,6-bis(hexyloxy)-4,5-bis(4-(trifluoromethoxy)phenoxy)phthalonitrile (1) and its metal-free (2)/metal {M = Zn (3), Cu (4), Co (5), Lu(CH3COO) (6), Lu (7)} phthalocyanines. A series of various spectroscopic methods (UV-vis, FT-IR, mass, and 1H NMR spectroscopy) were performed for the characterization of the newly synthesized compounds. The potential of compounds 2, 3, and 6 as photosensitizing materials for photodynamic and sonophotodynamic therapies was evaluated by photophysical, photochemical, and sonochemical methods. The highest singlet quantum yields were obtained for the zinc phthalocyanine derivative 3 by performing photochemical and sonochemical methods. In addition, several biological activities of the new compounds 1-7 were investigated. The newly synthesized phthalocyanines exhibited excellent DPPH scavenging activity and also DNA nuclease activity. The antimicrobial activity of the new compounds was evaluated by the disc diffusion assay. Effective microbial cell viability inhibition was observed with phthalocyanine macromolecules. The photodynamic antimicrobial therapy of the phthalocyanines showed 100% bacterial inhibition when compared to the control. They also exhibited significant biofilm inhibition activity against S. aureus and P. aeruginosa. These results indicate that new phthalocyanines are promising photodynamic antimicrobial therapies for the treatment of infectious diseases.

OBJECTIVES: We aimed to investigate the clinical and pathological factors of our patients who were diagnosed with endometrial cancer in terms of prognosis. With this study, we present our 10 years of surgical experience in endometrial carcinoma cases. MATERIAL AND METHODS: Four hundred twelve patients with endometrial carcinoma who applied to our center between 2010-2019 and that we followed up were evaluated retrospectively. RESULTS: Most of the tumors were low-grade endometrioid malignancies. Non-endometrioid types accounted for 12.1% of cases. Lymph node dissection was performed in 395 of 412 patients (95.9%). 66 (16.01%) of the 412 patients died during the follow-up period in the study sample. Higher OS and DFS rates were associated with endometrioid histological types, FIGO stage, absence of lymphovascular space invasion, lower grade and less than 50% myometrial invasion (p < 0.05). 5-year OS at stage 1, 2, 3, 4 was found as 88.9 ± 2.2%, 65.5 ± 10.8%, 49.4 ± 0.79% and 23.7 ± 0.97% respectively. 5-year DFS at stage 1, 2, 3, 4 was found as 84.1 ± 2.6%, 65.5 ± 10.8%, 47.7 ± 0.78% and 23.7 ± 0.97% respectively. In univariate analysis, Age, tumor histology, FIGO stage, histological grade, LVSI, positive peritoneal cytology, cervical involvement, myometrial invasion and not receiving adjuvant therapy were defined as prognostic factors. CONCLUSIONS: Age, grade, FIGO stage, myometrial invasion, histological type, LVSI involvement, cervical involvemet, positive peritoneal cytology and not receiving adjuvant therapy are important prognostic factors for progression-free survival and overall survival in patients diagnosed with endometrial cancer.

BACKGROUND: Epithelial tumors are the most common subgroup and are seen in 60-70% of all ovarian tumors. Serous cystadenoma and mucinous cystadenoma are the most common benign epithelial tumors. Serous cystadenomas are ovarian tumors with the highest bilateral incidence. The coexistence of tumors with different histopathology in the ovaries is extremely rare and has only been reported in a few cases in the literature. We present a case of bilateral ovarian tumor that was diagnosed as serous and mucinous cystadenoma after laparoscopic surgery. CASE REPORT: A 45-year-old female patient was admitted to our center with swelling in the pelvic region and pain in the left lumbar region. US imaging showed a cystic lesion in the right adnexal area, 4x2 cm in size, well-circumscribed, containing a few thin septa, and a low echo fluid content. A cystic lesion with 6x4cm sized multilocular, well-circumscribed, slightly high echo fluid content was observed in the left adnexal area. On CT, a complex cystic lesion measuring 6x4cm was observed in the left adnexal area, pushing the left ureter laterally and causing the hydroureter. In addition, a 4x2 cm cystic lesion was observed in the right adnexal area and hydroureter was observed on the right side proximal to this lesion. Both lesions were removed by surgery. On histopathologic examination, the left-sided cystic lesion was diagnosed as mucinous cystadenoma, and the right-sided cystic lesion was diagnosed as serous cystadenoma. CONCLUSION: The coexistence of different ovarian tumor subtypes is rare. In this article, we presented a case in which serous and mucinous cystadenoma lesions were seen together for the fourth time in the literature, according to our knowledge.

BACKGROUND: This study aimed to investigate the association of striae gravidarum (SG) and preterm delivery. MATERIAL AND METHODS: This prospective cross-sectional study was performed between November 2018 and February 2019. In addition to demographic variables, SG score of the abdomen, presence of striae on breasts, arms, hips, and thighs were recorded. Davey's scoring system was used to define the severity of SG in the abdomen by the same investigators. Patients with cervical dilatation of 6 cm or more were included in the preterm labor group. RESULTS: A total of 292 women were included in the study. Of these, 176 (60.3%) had no SG, 20 (6.8%) had mild SG, and 96 (32.9%) had severe SG. Davey's score was lower in the group of patients with preterm birth than in the term birth groups (p = .002). SG in the breasts was more common in the preterm labor group than in the term birth group (p = .007). Also, the presence of SG in the legs was less common in the preterm labor group than in the term birth group (p < .001). In a logistic regression model, stria in the breasts revealed most significant in preterm delivery. CONCLUSIONS: No difference was found in the pregnancy length in gestational weeks among groups of different SG severity. The Davey's score and the presence of striae in the legs and breasts were found different between the preterm and term birth groups, and the term birth subgroups.

OBJECTIVES: Caesarean section (CS) is one of the most frequently performed surgical procedures in the world and Turkey. In this study, we aimed to investigate the relationship between re-approximation of the rectus muscles during CS and the severity of diastasis recti abdominis in the first postoperative month. To investigate the relationship between re-approximation of the rectus muscles during CS and the severity of diastasis recti abdominis in the first postoperative month. MATERIAL AND METHODS: The study was designed as a prospective cross-sectional study. Patients were divided into two groups: parietal peritoneum closure only (Group 1), and closure of the parietal peritoneum and re-approximation of rectus muscle (Group 2). The distance between the rectus muscles and the thickest rectus muscle thickness were measured one month after CS from three anatomic regions using superficial ultrasonography by the same blinded physician. The anatomic regions were described as xiphoid, 3 cm above the umbilicus, and 2 cm below the umbilicus. The relation of the measurements between the groups was evaluated. RESULTS: There was a total of 128 patients, 64 in Group 1 and 64 in Group 2. There were no statistical differences between the groups in terms of the distance between rectus muscles and the thickness of rectus muscle at the described anatomic regions (p > 0.05). CONCLUSION: Re-approximation of rectus muscles has no effect on the prevention of diastasis recti, which is an important cosmetic problem.

The anti-proliferative effects of 5-methylquinolinium (5MQ) of nicotinamide N-methyltransferase (NNMT) have not been previously investigated on a cervical cancer cell line. NNMT is a metabolic enzyme that is correlated with tumour progression and metastasis. 5MQ is a small molecule inhibitor of NNMT. 0.1-500 µM of 5MQ was tested on the HeLa epithelial cervical cancer cell line. Cell viability was assessed with the MTT test. TWIST, ZEB1, SERPIN1, SIRT1, CD16, mRNA and various protein expression levels were analysed with Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) and Western Blotting, respectively. 5MQ significantly inhibited HeLa cell proliferation in a concentration and time-dependent manner. Increased cell shrinkage, loss of cellular adhesions and apoptotic bodies were observed in HeLa cells after 5MQ treatment. Following treatment with 5MQ, ZEB1, SIRT1, CD16 mRNA levels were increased while TWIST and SERPIN1 mRNA levels were reduced. Expressions of oncogenic proteins phospho-Akt and SIRT1 were decreased. 5MQ can effectively inhibit HeLa cell proliferation without apparently affecting HEK-293 cell proliferation.IMPACT STATEMENTWhat is already known on this subject? NNMT is a cytosolic enzyme involved in tumour progression, metastasis and treatment resistance. It was overexpressed in many human malignancies. 5-amino-1-methylquinolinium (5MQ) is a novel small molecule inhibitor of NNMT that has shown promising results in the treatment of obesity and in senescent muscle regeneration. 5MQ has not been tested on the HeLa cervical cancer cell line, previously.What do the results of this study add? In this study, 5MQ was tested on the HeLa cervical cancer cell line for the first time and the molecular changes associated with 5MQ treatment were analysed. 5MQ demonstrated significant anti-proliferative activity on HeLa cells, which displayed morphological signs of apoptosis. Treatment of HeLa cells with 5MQ led to an increase in ZEB1, SIRT1 mRNA while TWIST mRNA was decreased. Phospho-Akt and Sirtuin1 protein expressions were decreased.What are the implications of these findings for clinical practice and/or further research? 5MQ can effectively inhibit HeLa cell proliferation without apparently affecting HEK-293 cell proliferation. 5MQ treatment was associated with a decrease in the expression of phospho-Akt and Sirtuin1 proteins, both of which have been reported to maintain tumour progression. 5MQ can further be investigated and modified for anti-cancer therapy.
