The mode of delivery might prompt a long-lasting alteration in physiological and behavioral responsiveness in offspring.

This study was intended to evaluate if the mode of delivery could alter sensitivity to thermal and chemical stimuli in female rats.

56 adult female Wistar rats (200-220 gr) that were born by vaginal or cesarean section (C-section) were used (n = 28/each). Inflammatory pain was induced by subcutaneous injection of formalin into the hind paw. The thermal nociceptive threshold was determined by tail-flick and hot plate tests. Besides, the Western blot test was used to evaluate the spinal cord levels of c-Fos and c-Jun proteins.

Formalin-induced inflammation was significantly decreased in C-section group as compared to vaginally born rats (p < 0.001). The baseline nociceptive threshed and morphine-induced analgesia were significantly increased in C-section groups in comparison to vaginally born rats. In addition, the levels of c-Fos and c-Jun proteins were significantly decreased in the spinal cord of C-section rats as compared to vaginally born animals (p < 0.01). Morphine treatment could decrease the expression of c-Fos and c-Jun in the C-section group (p < 0.05).

Overall, C-section rats showed lower spinal nociceptive processing and neuronal activity later in life, compared to the vaginal born rats.

Due to the uncertainties of maternal and neonatal complications after delivery and the lack of similar studies in this regard, this study aimed to compare the maternal and fetal complications of vaginal birth after C-Section (VBAC), natural delivery and repeat Cesarean section in Isfahan province. In this one-year descriptive cross-sectional study, 49889 pregnant women who had the natural childbirth (29631 deliveries), elective repeat Cesarean section (20148 deliveries) and VBAC delivery (110 deliveries) were enrolled, then maternal and neonatal complications were compared in three groups. There was a significant difference between the three groups based on the maternal and neonatal outcome, Apgar scores in the first and fifth minutes after delivery and the need for resuscitation at birth (P <0.05). Neonatal outcome was better in natural delivery and then VBAC compared to repeat C-section, respectively. Maternal outcome was better in VBAC and then repeat C-section than the natural childbirth, Apgar scores in the first and fifth minute were better in VBAC, and later natural delivery than repeat C-section and resuscitation at birth demonstrated better results for natural delivery and then VBAC than repeat C-section. Utilizing VBAC and natural delivery have better maternal and fetal outcomes compared to C-section along with being more satisfactory and safer.

Umbilical cord hematoma and uterine torsion are extremely rare complications in pregnancy. However, these should not be neglected in clinical practice in condition of abnormal fetal heart monitoring without others suspects. We hereby report rare case of umbilical cord hematoma and uterine torsion as well as review the literature. Through this report, we aim to mention on an available tool to investigate spontaneous umbilical cord hematoma on fetal well-being in such a case.

A women aged 35 years old (G1P0) admitted to our hospital for term gestation with uncomplicated pregnancy, except large uterine fibroid accompanied with cervical pessary. Then, an uncommon complication of umbilical cord hematoma was revealed accidentally upon cesarean section. Particularly, this dramatic event was happened along with an asymptomatic uterine torsion noticed at the same time. Preoperative diagnosis of two rare complications was missed, hence, we extracted timely baby based on another modality of management, computerized cardiotocography.

Umbilical cord hematoma along with uterine torsion is difficult to diagnosis due to its rarity. Moreover, no available tool could investigate umbilical cord hematoma prior to delivery. Surveillance on fetal heart rate monitoring may be helpful in this situation.

The case report: The coexistence of physiological changes during pregnancy and infection can sometimes create challenges in the management of these patients. In this report, a term pregnant woman with COVID-19 infection was admitted to the ICU and underwent cesarean section (C-section) under intrathecal anesthesia according to the patientchr('39')s condition. Severe respiratory distress occurred to the patient on the first day after (C-section), and the patientchr('39')s pulmonary parameters were measured with a non-invasive ventilation monitor. It gradually improved during the four days after the C-section.  The C-section reduced the lung performance for 24 hours in a patient with COVID-19 infection, but eventually the lung symptoms improved.

Decisions on the choice of delivery method are influenced by various factors such as family and social aspects, medical advice, previous delivery experience, and current pregnancy conditions. The present study aimed to determine the frequency of delivery methods and their related factors in pregnant women in Shiraz. This cross-sectional descriptive study was conducted on 3940 pregnant women in Shiraz in 2016. All public hospitals with maternal care units in Shiraz were selected. Stratified sampling method, proportionate to the sample size, was used so that the number of registered pregnant women, during the year before the study, was determined for each center and the subjects were selected by convenience sampling. Data were collected through a checklist and was analyzed performing One-way ANOVA and chi-square test with SPSS 20 at the significance level of 0.05. The mean age of the pregnant women participating in the study was 29 ± 5.7 years. A total of 2003 pregnant women (50.8%) decided to give birth through cesarean section (C-section), 1849 (46.9%) through standard vaginal delivery, and 68 (1.7%) in water. The most prevalent reasons cited by pregnant women were fewer complications in NVD, fewer maternal and obstetric problems in C-section, and comfort of delivery in water. The age of women requesting C-section was significantly higher than those selecting NVD and delivery in water (P < 0.001). The prevalence of elective C-section was substantially higher in urban residents and women with higher education levels (P < 0.001). Physicians’ recommendation was mentioned as the most important reason for elective C-section by pregnant women (70.6%). Multivariable logistic regression showed that the fathers high school education, the age of mother, and living in a suburban area had a significant effect on choosing C/S as a method of delivery by pregnant women. Great inclination of pregnant women and physicians’ recommendation for elective C-section are the problems faced by the healthcare system. It can be minimized by planning and making effective interventions and through changing the attitude and culture of the community and increasing knowledge about the complications of C-section.

To anticipate the type of childbirth according to the health belief model.
The present cross-sectional research was conducted on 222 primiparous women visiting the healthcare center in Khorram Abad. A combination of simple randomization and clustering was used to do the sampling. The data collection instrument was a validated four-part questionnaire the first part of which contained demographic information. The second part was comprised of awareness questions while the third dealt with the constructs of the health belief model. The final part consisted of the behavioral intention derived from the logical action theory. SPSS 16 was used to statistically analyze the data and the significance level was set at p 0.05.
The average age of the participants was 27.40 ± 6.07 years. Intention to go for a vaginal birth showed to be significantly correlated with awareness, perceived sensitivity, intensity, barriers and benefits (p 0.001) as well as self-efficacy (p = 0.025). The best predictor of the type of childbirth turned out to be the perceived barriers (OR = 1.153, p 0.001) and only then awareness (OR = 1.108, p 0.001).
Strategies to remove the barriers of preferring vaginal childbirth, raising women’s awareness of the side effects of C-section and the benefits of vaginal birth, strategies to enhance women’s beliefs in their capability of natural childbirth can be used to reduce the prevalence of unnecessary C-sections.
