RESUMO

BACKGROUND: Cesarean delivery rates are increasing globally, raising concerns about associated complications such as isthmocele. Isthmoceles are pouch-like defects in the anterior uterine wall at the site of a prior cesarean delivery scar. OBJECTIVE: This study aimed to determine isthmocele prevalence, associated symptoms, and risk factors among women with a history of cesarean delivery. STUDY DESIGN: This cross-sectional study evaluated 297 women with prior cesarean delivery using transvaginal ultrasound to screen for isthmocele. Data on demographics, pregnancy details, comorbidities, and indications for cesarean delivery were collected. Isthmocele was defined sonographically as any niche or defect at the hysterotomy site. Descriptive and comparative analyses identified factors associated with isthmocele. RESULTS: Isthmocele prevalence was 65.3% (n=194). Abnormal vaginal bleeding was reported in 21.1% of participants, pelvic pain by 4.1% of participants, and both by 4.1% of participants. Compared to women without isthmocele, those with isthmocele were older (35.9 vs 31.6 years), had higher body mass index (26.8 vs 25.5 kg/m2), gravidity (1.8 vs 1.3), and parity (1.7 vs 1.2). Repeat cesarean delivery was more common (30.4% vs 12.6%) and elective cesarean delivery less common (33.5% vs 67.9%) among those with isthmocele. CONCLUSION: Over half of the women with history of cesarean delivery had an isthmocele. Abnormal bleeding was common. Advanced maternal age, obesity, repeat procedures, and certain comorbidities appear to increase risk. Further research on prevention and treatment is warranted given the high prevalence.

RESUMO

OBJECTIVE: Surgery and chemotherapy are the most common therapeutic strategies proposed for oral squamous cell carcinoma (OSCC). However, some of the disadvantages associated with the current methods like unwanted side effects and poor drug response lead the scientist to seek for novel modalities and delivery approaches to enhance the efficacy of treatments. The study aimed to assess the effectiveness of disulfiram (DSF)-loaded Niosomes on cancerous phenotypes of the OSCC cells. MATERIALS AND METHODS: In this experimental study, an optimum formulation of DSF-loaded Niosomes was developed for the treatment of OSCC cells to reduce drug doses and improve the poor stability of DSF in the OSCC environment. The design expert software was utilized to optimize the particles in terms of size, polydispersity index (PDI), and entrapment efficacy (EE). RESULTS: Acidic pH increased the release rate of DSF from these formulations. The size, PDI, and EE of Niosomes were more stable at 4°C compared to 25°C. The results indicated that DSF-loaded Niosomes could induce apoptosis (P=0.019) in the OSCC cells compared to the control group. Moreover, it could reduce colony formation ability (P=0.0046) and also migration capacity of OSCC cells (P=0.0015). CONCLUSION: Our findings indicated that the application of proper dose of DSF-loaded Niosomes (12.5 µg/ml) increases apoptosis, decreases colony formation capacity and declines the migration ability of OSCC cells.

RESUMO

BACKGROUND: Ovarian stimulation (OS) for poor ovarian response (POR) patients is still a major challenge in assisted reproductive techniques. Aromatase inhibitors as co-treatment in antagonist protocol are suggested to these patients, but there are controversial reports. OBJECTIVE: To evaluate the effectiveness Letrozole (LZ) as adjuvant treatment in gonadotropin-releasing hormone (GnRH)-antagonist protocol in POR patients undergoing in vitro fertilization/ intracytoplasmic sperm injection cycles. MATERIALS AND METHODS: This double-blind randomized clinical trial was conducted in Arash women's hospital. One hundred sixty infertile women with POR based on Bologna criteria were allocated into two groups randomly: LZ + GnRH-antagonist (LA) and placebo + GnRH-antagonist (PA) groups. In the experimental group, the patients received 5 mg LZ on the first five days of OS with 150 IU of recombinant human follicle-stimulating hormone (rFSH) and 150 IUof human menopausal gonadotropin (HMG). The cycle outcomes were compared between groups. RESULTS: The total number of retrieved oocytes and the metaphase II oocytes in LA-treated group were significantly higher than those in the control group (p = 0.008, p = 0.002). The dosage of hMG used and the duration of OS and antagonist administration in LZ-treated group were significantly lower than those of the control group. The number of patients with no oocyte, in the control group, was higher than the LZ-treated group, and the clinical pregnancy rate in LA-treated group (25%) was higher than the control group (18%); however, the differences were not significant statistically. CONCLUSION: Adding 5 mg of LZ to rFSH/hMG antagonist protocol may improve the in vitro fertilization/intracytoplasmic sperm injectioncycle outcome in POR patients.

RESUMO

BACKGROUND: Urinary tract infection (UTI) is the most common disorder caused by bacterial agents in pregnancy, which can lead to important complications in newborn of such mothers in case of inappropriate diagnosis and treatment. OBJECTIVES: The purpose of this study was to study the prevalence of UTI among pregnant women and its complications in their newborns during the birth in the hospitals of Dezful City, Iran, during 2012 - 2013. PATIENTS AND METHODS: In this cross-sectional retrospective study, 1132 women admitted to Dr. Ganjavian and Ayatollah Nabavi Hospitals in Dezful City, Iran, during 2012 - 2013 were randomly allocated into the case and control groups and were matched based on their age, numbers of pregnancy, sex and diseases of their children. UTI was the only difference between the two groups. RESULTS: Twenty-two thousand six hundred deliveries occurred within the course of this study. Due to UTI, 5% of deliveries led to hospitalization of mothers (1132 patients).Weight and height of newborn infants of mothers afflicted with UTI (P < 0.001) were significantly lower compared to newborns of healthy women (P < 0.001). There was a significant association between the two groups of pregnant women with UTI in terms of type of delivery (normal and caesarean section) (P < 0.008). CONCLUSIONS: The lower incidence of UTI in pregnant women compared to other areas of Iran represents the role of climate and weather in the prevalence of UTI. In addition, the increased number of low-birth-weight infants had a remarkable correlation with UTI, which can influence the health of the next generation.

RESUMO

BACKGROUND: Over one million new cases of breast cancer (BC) are diagnosed each year with a mortality rate of more than 600 thousand women per year. Breast self-examination (BSE) is a patient-centered, inexpensive, and noninvasive diagnostic test. We focused on the role of screening in BC in early diagnosis. OBJECTIVES: The purpose of this study was to evaluate awareness and attitude of women toward BSE in Dezful City, Iran, in 2013. PATIENTS AND METHODS: This descriptive cross-sectional study included 1020 women over 15 years of age in Dezful City, in 2013. Simple random clustering was used to enroll accessible women. We have applied the available pieces of software for statistical analysis. RESULTS: The mean age of recruited women was 37.1 ± 1.3 and 23.6% of participants had a history of BC in themselves or in their relatives (mother, sister, aunt, and grandmother). In addition, 70.1% of participants benefited from early diagnosis of BC, 83.3% of participants considered BSE necessary and useful for early diagnosis of BC, and 51% of them performed BSE. There was a statistically significant correlation between being married and doing BSE (P = 0.034) and between women's level of education and awareness to perform BSE (P = 0.009). CONCLUSIONS: With regard to high prevalence of BC in Iran, this study showed a positive attitude of women in Dezful City toward BSE. Health policymakers in Dezful City can establish training programs to increase women's awareness of BSE and to instruct them to perform it properly.
