Purpose: Cesarean section (CS) rates have increased; this is especially concerning in developing countries. The mode of placental delivery contributes to morbidity associated with CS and determines blood loss during CS. We aimed to compare manual removal versus spontaneous delivery of the placenta at CS. Methods: In a randomized controlled trial, 574 women admitted for primary or repeat elective CS were randomized into two groups. In group A, the placenta was manually removed, whereas in group B, the placenta was left for spontaneous delivery. Blood loss, operative and postoperative data were recorded. Results: Blood loss was 875.2 ± 524.2 ml in group A versus 731.8 ± 426.7 ml in group B (p = .001), with a significant drop in postoperative HB (p = .015) and HCT (p = .031). In group A, odds ratios for blood loss (>1000 ml), HB drop (> 4g/dl), postpartum hemorrhage and blood transfusion were 2.581, 2.850, 2.614 and 1.665, respectively. However, the total operative time (p = .326), duration of hospital stay (p = .916) and intensive care unit (ICU) admission (p = .453) were not statistically different between the two groups. Conclusions: Manual removal of the placenta at CS is associated with a higher risk of blood loss, postpartum hemorrhage and blood transfusion, with no decrease in operative time.

Purpose: To study the effect of intramural fibroids on uterine and endometrial vascularity in infertile women scheduled for in-vitro fertilization (IVF).Methods: 3D power Doppler was used to measure the endometrial volume and blood flow indices in 182 women with intramural fibroids not affecting the uterine cavity and compared them to a matched control group without fibroids.Results: There was significantly increased vascularity in the endometrium of the fibroid group as denoted by higher endometrial VI (p = 0.018), FI (p = 0.027) and Endometrial VFI. No significant difference in mean uterine artery RI (p = 0.277) or PI (p = 0.187). Among the fibroid group 62.6% had a fibroid > 4 cm. Women with fibroids > 4 cm had a significantly higher Endometrial FI (p = 0.037), and VFI (p = 0.02). Uterine artery blood flow was not affected, as uterine RI (p = 0.369) and PI (p = 0.321) were not statistically different. Compared with the control group (non fibroid), women with fibroids > 4 cm had significantly higher endometrial VI (p = 0.013), FI (p = 0.004), and VFI (p < 0.001), whereas women with fibroid ≤ 4 cm had no statistically significant differences in VI (p = 0.292), FI (p = 0.198), and VFI (p = 0.304).Conclusion: Intramural fibroids > 4 cm significantly increase endometrial vascularity. This increase in blood flow may be a factor that affects the outcome of IVF. [ABSTRACT FROM AUTHOR]

Purpose:To investigate the ability of anti-Mullerian hormone (AMH) to predict the step up of human menopausal gonadotropins (HMG) dose in women with polycystic ovarian syndrome (PCOS) undergoing IVF/ICSI cycles. Methods:AMH was drawn before ovulation induction in 976 PCOS women scheduled for IVF/ICSI. After all cycles ended, a receiver operating characteristic (ROC) curve analysis was done to investigate the ability of AMH to predict step up of the HMG. Results:The area under the curve (AUC) was 0.820 95%CI (0.792–0.848), and a cutoff value of 4.6 ng/ml (sensitivity 74%, specificity 82%) for AMH was taken (p < 0.01). Cases were divided into two groups retrospectively; group (A) (AMH ≤4.6 ng/ml), and group (B) (AMH >4.6 ng/ml). No difference in the mean age (p = 0.147); BMI (p = 0.411), basal FSH (p = 0.221), and starting dose (p = 0.195); however, the dose at which the first response occurred was higher in group (B) (p < 0.01). The total dose and number of days were higher in group (B) (bothp < 0.01) irrespective of the PCOS subtype or androgen levels. Severe OHSS was also higher in group (B) (p = 0.026). Conclusions:PCOS with AMH >4.6 ng/ml are resistant to HMG stimulation, require dose step up during ART cycles, and are at higher risk for severe OHSS. [ABSTRACT FROM AUTHOR]

Aim: The aim of our study was to compare the outcome of pregnancy in patients who became pregnant within 24 months of renal transplantation and patients who became pregnant more than 24 months after renal transplantation. Materials and methods: The sample population of our prospective cohort study comprised of 44 patients who became pregnant following renal transplantation. In all cases, living donors were used for renal transplantation. The patients were allocated into either group A, which included 24 patients who became pregnant more than 24 months after renal transplantation, or group B, which included 20 patients who inadvertently became pregnant within 24 months of renal transplantation. Serum creatinine and 24-hour urinary protein concentration were measured each trimester. The incidences of preeclampsia and gestational diabetes, the timing and mode of delivery, the rate of preterm labor, and the mean fetal birth weight were determined. Results: The mean gestational ages in groups A and B were 35.8±3 weeks and 34.1±2.5 weeks, respectively. The mean fetal birth weights in groups A and B were 2,480±316 g and 2,284.5±262 g, respectively. These differences were statistically significant. The incidence of preterm labor was 45.8% in group A and 55% in group B. Proteinuria was significantly higher in group B during the third trimester of pregnancy. Preeclampsia occurred in 25% of the cases in group A and 30% of the cases in group B; this difference was not statistically significant. Gestational diabetes occurred in 2 out of 24 cases in group A and 2 out of 20 cases in group B. For group A and group B, normal vaginal delivery occurred in 58.3% and 55% of cases, respectively, and cesarean section was performed in 41.6% and 45% of cases, respectively. Conclusion: A longer interval between renal transplantation and pregnancy is associated with better pregnancy outcome. [ABSTRACT FROM AUTHOR]

Purpose: To determine the sonographic criteria for diagnosis of fetal intracranial hemorrhage (ICH), using both gray scale ultrasound, and tomographic ultrasound imaging (TUI).Materials and Methods: A prospective multicenter study, recruiting patients at risk of fetal ICH over four years. All cases with fetal ICH had serial ultrasound assessments, including TUI, fetal and postnatal MRIs.Results: Twenty-one patients were diagnosed with fetal ICH, two cases had extracerebral (subdural) hemorrhage, 16 cases had intracerebral (intraventricular) hemorrhage and three cases had combined hemorrhage. The mean gestational age at which they were diagnosed was 29.8 ± 5.2 weeks. Seventy-six percent of cases had no identifiable risk factors. IUGR was associated with 57.9% of cases. Using grey scale ultrasound, we demonstrated clear cut sonographic criteria for diagnosis of fetal ICH. TUI enabled us to detect some midline cerebral lesions not detected by grey scale 2D ultrasound alone. Fetal and postnatal MRI confirmed those findings.Conclusion: Ultrasonography can be used in the detection, classification and monitoring the progression of various types of ICH. TUI is an additional diagnostic tool that might help to detect the exact size, and extent of those lesions. Fetal MRI is not superior, but might aid in the diagnosis. [ABSTRACT FROM AUTHOR]

Objective: To study the preconceptual & early conceptional risk factors predisposing to the development of spina bifida (SB) among Egyptian population. Study design: The study involved 197 pregnant women undergoing fetal anatomy scan; 97 women proved to have fetal SB and 100 women with normal fetuses as a control group. The control group was recruited randomly in the same period from patients undergoing anatomical scan. Risk factors that might lead to SB were investigated including maternal age, gravidity, parity, residence, history of diabetes mellitus or drug intake, smoking, infections, exposure to X-ray, history of congenital anomalies in other offspring, parental consanguinity, positive family history, and folate supplementations. Results: SB affected the lumbo-sacral region in the majority of cases (89.7%). It was associated with hydrocephalus in 66 cases (68%), polyhydramnios in 12 cases (12.4%). The SB group showed significantly higher parity (p = 0.005), more frequent history of drug intake (p < 0.001), higher frequency of infection with CMV (p = 0.004), and HSV (p = 0.013) and less proportion of folate supplementation (p < 0.001). Conclusion: The rate of SB in the tested group was five per 1000. Risk factors were lack of folate supplementation and history of antiepileptic drugs intake. [ABSTRACT FROM PUBLISHER]

Triple negative breast cancer (TNBC) cells are resistant to hormonal/targeted therapies. This study aims to investigate epigenetic differences between TNBC and other types of breast cancer and the effect of epigenetic modulation on the response of TNBC cells to hormonal therapy. Thus, we investigated (i) the expression of different epigenetic markers, (ii) the effect of epigenetic modifying agents on the expression of ERα and HER2/ERBB2 and (iii) the effect on the response to tamoxifen in four breast cancer cell lines with different hormonal receptor status. Our results revealed a differential expression patterns of epigenetic markers in the four breast cancer cells. In TNBC cells, histone deacetylases (HDAC) 1 and 2 were less expressed, whereas HDACs 4 and 6 were overexpressed. Interestingly, treatment with epigenetic modifiers resulted in (i) a pronounced increase in the expression of ERα and HER2/ERBB2 along with (ii) an increase in the sensitivity of TNBC cells to tamoxifen. Collectively, this study indicates a different epigenetic background for TNBC cells, which represses the expression of ERα and HER2/ERBB2. Furthermore, we provide here the rationale for the use of epigenetic modifiers to enhance the response of TNBC to hormonal therapy through upregulation of ERα. [ABSTRACT FROM AUTHOR]

Background: Cisplatin (CIS) is one of the most effective anticancer drug used in the treatment of several solid tumors.Its use is limited by its nephrotoxicity. The present study was designed to assess the role of a natural product resveratrol (RSVL) on sensitization of mammary carcinoma (Ehrlich ascites carcinoma) to the action of CIS and the possible protective effect against CIS-induced nephrotoxicity in rats. Methods: The percent survival of female tumor bearing mice was used for determination the cytotoxic activity of CIS in the presence or the absence of RSVL. Uptake and cell cycle effect, serum creatinine (CREA), blood urea nitrogen (BUN), Reduced Glutathione (GSH) and histopatholgical examination of kidney tissues after CIS and/or RSVL therapy were also investigated. Results: RSVL increased the intracellular level of CIS in EAC cells and there was a strong correlation between the high cellular level of CIS and its cytotoxicity. CIS at a dose level of 5 mg/kg increased the mean survival time of female tumor bearing mice to 25 days compared with 17 days for tumor-bearing control mice. Administration of RSVL at a dose level of 25 mg/kg simultaneously with CIS increased the mean survival time to 48 days with 60% survival of the tumor-bearing animals. Cell cycle analysis of tumor cells showed that CIS treatment decreases the proliferation index of tumor cells while in presence of RSVL there was more significant inhibitions. Also, CIS treatment caused increase in level of creatinine and blood urea with significant decrease in the GSH level. While, in the presence of RSVL, level of creatinine and blood urea restored to control level. Conclusion: This study suggests that RSVL could increase the cytotoxic activity of CIS and protect against its nephrotoxicity. [ABSTRACT FROM AUTHOR]

Introduction: Bowel cancer is a significant global health concern, ranking as the third most prevalent cancer worldwide. Laparoscopic resections have become a standard treatment modality for resectable colorectal cancer. This study aimed to compare the clinical and oncological outcomes of medial to lateral (ML) vs lateral to medial (LM) approaches in laparoscopic colorectal cancer resections., Methods: A retrospective cohort study was conducted at a UK district general hospital from 2015 to 2019, including 402 patients meeting specific criteria. Demographic, clinical, operative, postoperative, and oncological data were collected. Participants were categorised into LM and ML groups. The primary outcome was 30-day complications, and secondary outcomes included operative duration, length of stay, lymph node harvest, and 3-year survival., Results: A total of 402 patients (55.7% males) were included: 102 (51.6% females) in the lateral mobilisation (LM) group and 280 (58.9% males) in the medial mobilisation (ML) group. Right hemicolectomy ( n =157, 39.1%) and anterior resection ( n =150, 37.3%) were the most performed procedures. The LM group had a shorter operative time for right hemicolectomy (median 165 vs. 225 min, P <0.001) and anterior resection (median 230 vs. 300 min, P <0.001). There was no significant difference between the two groups in terms of wound infection ( P =0.443), anastomotic leak ( P =0.981), postoperative ileus ( P =0.596), length of stay ( P =0.446), lymph node yield ( P =0.848) or 3-year overall survival rate (Log-rank 0.759)., Discussion: The study contributes to the limited evidence on ML vs LM approaches. A shorter operative time in the LM group was noted in this study, contrary to some literature. Postoperative outcomes were comparable, with a non-significant increase in postoperative ileus in the LM group. The study emphasises the safety and feasibility of both approaches., Competing Interests: The authors declare no conflicts of interest.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2024 The Author(s).

DNA-dependent protein kinase (DNA-PK), a member of phosphatidylinositol-kinase family, is a key protein in mammalian DNA double-strand break (DSB) repair that helps to maintain genomic integrity. DNA-PK also plays a central role in immune cell development and protects telomerase during cellular aging. Epigenetic deregulation due to endogenous and exogenous factors may affect the normal function of DNA-PK, which in turn could impair DNA repair and contribute to genomic instability. Recent studies implicate a role for epigenetics in the regulation of DNA-PK expression in normal and cancer cells, which may impact cancer progression and metastasis as well as provide opportunities for treatment and use of DNA-PK as a novel cancer biomarker. In addition, several small molecules and biological agents have been recently identified that can inhibit DNA-PK function or expression, and thus hold promise for cancer treatments. This review discusses the impact of epigenetic alterations and the expression of DNA-PK in relation to the DNA repair mechanisms with a focus on its differential levels in normal and cancer cells., (Copyright © 2018.

Objective: The aim of this study was to compare the efficacy and tolerability of iron amino acid chelate (IAAC) and ferrous fumarate (FF) in treatment of iron deficiency anemia (IDA) with pregnancy., Study Design: A total of 150 pregnant women having iron deficiency anemia (IDA) were randomized to receive either IAAC or FF for 12 weeks. Hemoglobin, red cell indices, serum iron, and serum ferritin were measured at baseline and then 4, 8, and 12 weeks after treatment. Adverse effects were questioned in both groups., Results: The mean values of hemoglobin, red cell indices, serum iron, and serum ferritin were not significantly different between both groups after 12 weeks of treatment. However, the rise in hemoglobin level after 4, 8, and 12 weeks of treatment was significantly faster in the IAAC group (p=<0.001). Constipation and abdominal colicky pain were significantly more common in the FF group (p=0.022 and 0.031 respectively)., Conclusion: IAAC and FF are comparable in curing IDA with pregnancy; however, IAAC has the advantage of providing a faster rate of improvement of hemoglobin level and is better tolerated by the patients., (Copyright © 2017 Elsevier B.V.

Objective: To evaluate the effect of hydrosalpinx on uterine and ovarian blood flows in women with tubal factor infertility., Study Design: In a cross-sectional study at a university teaching hospital, 60 women with hydrosalpinx-related tubal infertility (hydrosalpinx group) were compared with 60 women with male or unexplained infertility (non-hydrosalpinx group). In the mid-luteal (peri-implantation) phase of the cycle, endometrial thickness, uterine and ovarian artery pulsatility index (PI) and resistance index (RI), and endometrial and ovarian volume and 3D power Doppler vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were measured in both groups., Results: The endometrial VI (p=0.002), FI (p=0.041), and VFI (p=0.018), and ovarian VI (p=0.011), and VFI (p=0.015) were significantly lower in the hydrosalpinx group than in the non-hydrosalpinx group. However, the endometrial thickness, uterine artery PI and RI, ovarian artery PI and RI, endometrial volume, and ovarian volume and FI were not significantly different between the two groups., Conclusion: Hydrosalpinx is associated with impaired endometrial and ovarian blood flows which may adversely affect endometrial receptivity and oocyte quality., (Copyright © 2016 Elsevier Ireland Ltd.
