The aim of this study was to find the causes of failure of natural childbirth in late-term pregnancy that can be useful for managing childbirth in these pregnant mothers and to design a solution to increase natural childbirth.

This cross-sectional study was conducted in the community of pregnant women with a late-term pregnancy of more than 41 weeks. The studied sample includes 148 pregnant mothers who were referred to Ayatollah Rouhani Hospital in Babol from March 2018 to February 2020. Mother's age, Body Mass Index, gestational age, number of pregnancies, number of deliveries, length of hospitalization, the state of the cervix and preparation method of the cervix for termination of pregnancy were extracted and recorded from patients' files. Data were compared in two groups of pregnancy termination methods (natural childbirth and cesarean delivery). Statistical analysis was done using SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) and Chi-square test and Student’s t-test statistical tests and logistic regression model fitting. P-value less than 0.05 was considered significant.

In this study, 167 pregnant women with late-term pregnancy were studied. The age of pregnant women is reported with mean of 26.03 and standard deviation 5.98 of years. The high Bishop variable, with odds ratio of 0.44, is a variable protective factor for cesarean delivery (P=0.001). Higher body mass index with odds ratio of 1.09, is also known as a risk factor for cesarean delivery (P=0.01), so that for each unit of increase in Bishop score, the chance of cesarean delivery decreases by 56% and for each unit of increase in body mass index, the chance of cesarean delivery increases by 9%.

This study showed that nearly half of cases of late pregnancies lead to normal delivery. High body mass index reduces the chance of normal delivery in late term pregnancies. But a higher Bishop score can be effective in the success of natural delivery.

Supplying vitamin D during pregnancy is necessary for fetal calcium homeostasis and bone growth and its mineralization, and its deficiency can lead to pregnancy complications. The present study was conducted to investigate the effect of vitamin D level on pregnancy outcomes in pregnant women.

This cross-sectional study was conducted among 450 pregnant women referring to Ayatollah Rouhani Hospital in Babol. Mothers' information was collected using a questionnaire. Blood samples were collected from people to measure the serum 25 hydroxyvitamin D3 level by ELISA method using the EUROIMMUN kit. Patients were divided into two groups (vitamin D level< 25 and vitamin D level> 25) and were compared.

247 people (54.8%) had vitamin D level< 25 and 203 people (44.8%) had vitamin D level> 25. People with lower vitamin D levels had significantly more gestational hypertension (p=0.03) and premature rupture of membranes (PROM) (p=0.04) compared to people with higher vitamin D levels. The variables of labor pain, diabetes, fetal growth restriction and prolonged pregnancy did not show significant differences in people with high and low levels of vitamin D. Pregnancy complications including pre-eclampsia, preterm delivery, placental abruption and fetal growth restriction did not show any significant difference in people with high and low levels of vitamin D. In the evaluation of neonatal outcomes, infant weight, infant gender, fifth minute Apgar, head circumference and admission to the neonatal intensive care unit, no significant differences were found.

The results of the study showed that some pregnancy complications such as gestational hypertension and premature rupture of membranes (PROM) in pregnant women are related to vitamin D deficiency. Therefore, it is necessary to design plans to check the vitamin D level of mothers before pregnancy and correct it during pregnancy.

Human papillomavirus (HPV) is one of the common infectious and pathogenic agents, and some of its genotypes have the ability to cause malignant changes in the surface of mucous cells. By examining the prevalence of HPV in atypical squamous cells of undetermined significance (ASCUS) Pap smear according to the risk factors, we can make a more correct decision in choosing the evaluation method and directing the patient to report the ASCUS lesion. Therefore, the aim of this study is to investigate the types of human papillomavirus (HPV) in patients with ASCUS Pap smear.

This cross-sectional study was conducted on 200 patients with ASCUS pap smear results and HPV test referred to the colposcopy clinic of Babol Ayatollah Rouhani Hospital during the last two years. Demographic information, history of obstetrics, history of OCP use, history of STD disease and high-risk behaviors, cervical treatments, HPV typing, Pap smear, colposcopy and cervical biopsy results were recorded and analyzed.

The mean age of the patients was 33.83±8.09 years, and ASCUS pap smear showed 129 cases (64.5%) of high-risk papillomavirus, 16 cases (0.8%) of low-risk papillomavirus and 55 cases (27.5%) of both types. Cervical intraepithelial neoplasia grade 2 was in 18 cases (0.9%), cervical intraepithelial neoplasia grade 1 in 10 cases (0.5%) and cervical intraepithelial neoplasia grade 3 in 2 cases (0.1%). 17.1% of high-risk viruses caused cervical neoplasm. None of the low-risk viruses led to neoplasms and all of them were inflammatory. In both high-risk and low-risk cases, 14.5% neoplasm was seen. However, the relationship between the type of papillomavirus and the incidence of neoplasm was significant (p=0.058).

Based on the results of this study, the ASCUS pap smear needs more detailed investigation such as colposcopy and cervical biopsy under the supervision of experts because it is associated with the high-risk HPV virus in many cases.

HELLP syndrome is a serious presentation of pre-eclampsia and eclampsia during pregnancy and its diagnosis is difficult because of lack of specific features. This syndrome is associated with prenatal and neonatal morbidity and mortality. The aim of the present study was to compare the maternal and neonatal outcomes of HELLP syndrome with preeclampsia in Yahyanejad hospital (Babol, Iran) in the past ten years.

This cross-sectional study was performed on all patients with pre-eclampcia/eclampcia who were hospitalized in Yahyanejad hospital during 10 years. Primary data, clinical and laboratory data, prenatal and maternal complications included (cesarean section, placental abruption, need to blood transfusion, liver hematoma, pulmonary edema, acute renal failure, DIC, brain hematoma and infection, intra-abdominal hemorrhage, ARDS and maternal mortality) and neonatal complications included (preterm neonates, IUGR, NICU admission and neonate mortality) were compared.

In this study, from 445 patients who were evaluated, 361 patients (81.3%) with mild preeclampsia, 83 patients (18.7%) with severe pre eclampsia and 1 (%0.2) with eclampsia were hospitalized in primary diagnosis, that 12 patients (2.7%) had HELLP syndrome symptoms. Cases of placental abruption, liver hematoma, pulmonary edema, need to blood transfusion, acute renal failure, DIC and maternal mortality in patients with HELLP syndrome was significant in compared to preeclampsia (p<0.05). Neonatal complications included preterm neonates, IUGR, NICU admission in patients with HELLP syndrome were significant in compared to preeclampsia (p<0.05). Also no case of brain hemorrhage and infection, ARDS, intra-abdominal hemorrhage, IUFD and neonatal mortality was reported.

According to the results of this study, maternal and fetal complications in patients with HELLP syndrome can be prevented and this could be result of early diagnosis and appropriate management.
