Objective Hypovitaminosis D3 is a significant concern among pregnant women and their newborns because vitamin D3 (Vit-D3) plays a crucial role in embryonic growth, development, and health. This study aimed to evaluate the Vit-D3 status of a group of pregnant Iranian women and its association with newborn Vit-D3 levels, medical and clinical indices after delivery.Methods A total of 206 pregnant women and their newborns were assessed for Vit-D3 levels and their correlation with gestational age. Mean±standard deviation (SD) or the orders (non-parametric tests) of variables were compared, and correlation estimations were performed to elucidate any differences or associations between groups, with a confidence interval of at least 0.95.Results The mean±SD of mothers’ age and gestational age were 29.65±6.18 years and 35.59±1.6 weeks, respectively. Neonatal Vit-D3 levels were associated with maternal age. Using a 30 ng/mL cutoff point for serum Vit-D3 levels, 83.5% of pregnant women and 84.7% of newborns had hypovitaminosis D3. The average Vit-D3 levels of mothers and newborns at delivery time were 23.5±8.07 ng/mL and 20.76±9.14 ng/mL, respectively. Newborn Vit-D3 levels were positively correlated with maternal Vit-D3 serum levels (R=0.744; <i>P</i><0.001) and gestational age (R=0.161; <i>P</i>=0.022). In newborns, head circumference was inversely correlated with bilirubin level (R=-0.302; <i>P</i><0.001) but directly associated with weight (R=0.640; <i>P</i><0.001).Conclusion Hypovitaminosis D3 remains a significant challenge for pregnant Iranian women. Maternal Vit-D3 levels provide for the newborn’s needs, particularly in the late stages of pregnancy. Therefore, Vit-D3 supplementation and regular monitoring are essential for pregnant women and their newborns.
Backgrounds: Changes in estrogen levels during pregnancy as well as histologic changes in breast tissue can justify the relationship of preterm birth (PTB) and the risk of BC. Therefore, there is a hypothesis that the duration of pregnancy can be associated with BC, so the aim of this study was to find out whether PTB is a risk factor for BC. Methods: Published studies were located back to the earliest available publication date (1983), using the Medline/ PubMed, Embase, Scopus, and Web of Science bibliographic databases. This review included the cohort or case control studies that assessed the association between PTB and BC. Pooled effect sizes with corresponding 95% confidence intervals (CI) were calculated using random-effects models. Results: Thirteen studies including a total of 2,845,553 women were included in this meta-analysis. Pooled results suggested that PTB could increase the risk of BC (RR: 1.03, 95% CI: 1.00, 1.07; I2= 62.5%). The risk was significantly increased in women who delivered at 37-39 (RR: 1.03, 95% CI: 1.01, 1.06) and 26-31 weeks of gestation (RR: 1.25, 95% CI: 1.04, 1.47) compared to women who delivered at 40-41 weeks of gestation. A significant increment in the risk of BC was observed in primiparous (RR: 1.05, 95% CI: 1.01, 1.08) and women older than 45 years (RR = 1.12, 95% CI: 1.01, 1.24). There was no difference between other gestational age categories. Conclusions: Our findings add to evidence that short gestation pregnancies may increase the risk of BC, especially in primiparous and women older than 45 years. Considering the methodological weaknesses existed in included studies, minor clinical differences, and the complexity of the exact pathophysiology of PTB on BC, the precise position of PTB as a risk factor for BC in clinical practice is undetermined. Further studies are still needed.
Background Based on previous studies, it has been hypothesized that tube sterilization may be associated with a lower risk of breast cancer. This study aims to investigate the relationship between tubal ligation and the risk of breast cancer through a systematic review and meta-analysis. Methods In this systematic review and meta-analysis, PubMed/Medline, Web of Science, Scopus, and Google Scholar were searched for relevant non randomized studies published up to November 2020. Then, we screened the papers to include the eligible papers in the meta-analysis. Finally, we pooled the extracted results of individual studies to estimate the summary effect size. All analyses were done using Stata software version 13 (Stata Corp, College Station, TX). Results Four hundred sixty-four papers were retrieved from PubMed/Medline (160), Scopus (165), and Web of Science (139), and 21 papers from Google Scholar and manual search of references in selected full texts. After the removal of duplicates and screening of the papers, 11 articles (6 cohort and 5 case-control study) were included in the final analysis. The results of cohort (RR = 0.99, 95% CI = 0.97–1.0, I2 = 21.1%) and case control studies (OR = 0.87, 95% CI = 0.62–1.12, I2 = 88.9%) revealed that tubal ligation was not significantly associated with breast cancer risk. Conclusion According to our findings, tubal ligation cannot be considered as a risk factor associated with breast cancer risk.
Backgrounds: Abnormal vaginal discharge is a common problem among pregnant women. The most common cause of these discharges is bacterial vaginosis (BV), which has numerous complications and causes problems for pregnant mothers and their fetuses. The purpose of this study was to determine the BV frequency among pregnant women referring to a gynecology clinic in Arak city using Amsel and Nugent criteria, Alberta guideline, and PCR. Materials & Methods: This descriptive study was performed on 70 vaginal samples of pregnant women in Arak to investigate the most common causes of vaginal discharge according to Amsel and Nugent criteria and polymerase chain reaction (PCR) method using specific primers targeted towards three bacteria: Gardnerella vaginalis, Atopobium vaginae, Mobiluncus curtisii. Data were analyzed using SPSS software and Chi-square test. Findings: In this study, ten (14.28%) out of 70 pregnant women had positive bacterial vaginosis according to Amsel criteria. According to Nugent criteria and Alberta guideline, three (4.29%) cases were diagnosed with definite BV, 20 (32.26%) cases with intermediate BV with clue cells, 42 (67.74%) cases with intermediate BV without clue cells, and finally five (4.29%) cases with negative BV. Also, according to PCR, the frequency of G. vaginalis, M. curtisii, and A. vaginae in vaginal samples was 71.42% (50 cases), 64.28% (45 cases), and 30% (21 cases), respectively. Conclusion: According to the obtained results, the prevalence of definite bacterial vaginosis was lower than that of vaginitis, and most patients suffered from nonspecific vaginitis.
Introduction: cesarean is one of the major surgeries after which mother will need to be hospitalized for a long period of time. One of the leading causes of the increase in the duration of hospitalization of such patients is the surgeons’ projections about the development of ileus and defecation. Given the previous studies, misoprostol can increase bowel movements. Moreover, gum-chewing has been recommended as a cheap and available technique for accelerating the resumption of normal Intestinal Movements. Methods and materials: the present study is a single-blind randomized clinical trial which has been done on 324 women over 18 years of age with singleton pregnancy who had visited Taleghani Hospital in Arak and was elective cesarean section candidates. The surgery and anesthesia techniques were similar for all patients. These patients were randomized into three groups of 108, namely control, misoprostol, and gum-chewing groups. The patients in these three groups were compared with one another in terms of normal bowel sound, gas passage, defecation and discharge. Results: the results have shown the mean age of a total of 324 patients has been 26.66 years. The results suggest that the time of hearing the first normal bowel sound, the first gas passage, and defecation have been shorter in the misoprostol group, gum-chewing group and control group, respectively. The difference observed between the three groups has been significant at a 0.05 significance level. Furthermore, no significant difference was observed between the patients in the misoprostol and gum-chewing groups and the patients in the control group while reviewing the time of discharge of these patients. Conclusion: the findings have been indicative of the positive effects of the misoprostol and gum-chewing techniques on the intestinal function of patients and mothers’ breastfeeding. Also, it has been observed that using misoprostol can be more effective than chewing gum.
