Abstract Background The COVID-19 pandemic has affected many countries around the world and Iran was no exception. The aim of this study was to evaluate health anxiety of Iranian pregnant women during the COVID-19 pandemic. Methods In this cross-sectional study, 300 pregnant women in different trimesters (n = 100 in each trimester) were recruited. A demographic questionnaire and the Health Anxiety Questionnaire were used to collect data. Scores of < 27, 27–34 and more than 35 were defined as low, moderate and high health anxiety, respectively. Due to nationwide restrictions, data were collected through social media groups. Chi-square tests, ANOVA and multiple linear regression were used to analyze the data. Results Mean (SD) total anxiety scores were 22.3 ± 9.5, 24.6 ± 9.3 and 25.4 ± 10.6 in the first, second and third trimesters of pregnancy, respectively. 9, 13 and 21% of women had severe anxiety in the first, second and third trimesters of pregnancy, respectively. Women in the third trimester had significantly higher health anxiety scores than those in the first trimester (p = 0.045). Conclusion At the time of the COVID-19 pandemic, women in the second and third trimesters of pregnancy were more worried about consequences of disease, but total health anxiety scores were significantly higher among women in the third trimester of pregnancy. Health care providers should pay more attention to the mental health of pregnant women in times of crises such as the COVID-19 pandemic.

Abstract Background Iron deficiency is a leading cause of anemia among pregnant women in Uganda. However, due to the high cost of biochemical tests required to determine iron deficiency, the prevalence and factors associated with iron deficiency remain largely unstudied in our setting. Therefore, this study aimed at determining the prevalence of iron deficiency and its associated factors among pregnant women attending an antenatal clinic, Lira District-Uganda.Methods A cross-sectional study was conducted among 320 pregnant women attending an antenatal clinic at Lira Regional Referral Hospital. Maternal serum ferritin was used as a measure of iron deficiency and was determined using a Cobas 6000 Automated Analyzer. Iron deficiency was based on serum ferritin of <30 μg/L. A semi-structured questionnaire was used to obtain the characteristics of the study participants. Binary and multivariate logistic regression were performed to identify the associated factors.Results The prevalence of iron deficiency was 45%. Non-adherence to iron supplements (AOR: 2.05 95% CI: 1.02-4.12) & third trimester pregnancy (AOR: 1.88 95% CI: 1.20-2.94) were significantly associated with iron deficiency during pregnancy.Conclusion Nearly 5 in 10 of the participants had iron deficiency. Iron deficiency during pregnancy was associated with non-adherence to iron supplements and being in the third trimester of pregnancy. Midwives should encourage pregnant women to adhere to iron supplements during pregnancy especially pregnant women who are in the third trimester.

1. The intracellular free calcium concentration ([Ca2+]i) in washed human platelets was measured using the fluorescent indicator, fura-2, in a cross-sectional study of 36 normotensive, primigravid volunteers, 12 in each trimester of pregnancy and a further 12 at 6 weeks post partum. The results were compared with those obtained from 30 normal female volunteers not using oral contraception. 2. The mean basal [Ca2+]i in the platelets of the pregnant women in the first two trimesters (115.6 ± 6.7 and 120.1 ± 5.7 nmol/l, respectively) was not shown to differ significantly from that of normal non-pregnant volunteers (112.3 ± 2.9 nmol/l). However, during the third trimester a significant increase in [Ca2+]i was noted (134.0 ± 4.9 nmol/l; P < 0.05), with a return to normal values in the post-partum period (108.2 ± 6.1 nmol/l). 3. [Ca2+]i was also measured in the platelets of a group of 12 primigravid pregnant women in the third trimester whose pregnancies were complicated by gestational hypertension (pregnancy-induced hypertension and preeclampsia). A significant rise in basal [Ca2+]i was noted in the platelets of primigravidae whose pregnancies were complicated by pre-eclampsia (163.6 ± 8.8 nmol/l) as compared with normotensive, third-trimester primigravidae (P < 0.02). However, no correlation could be demonstrated between [Ca2+]i and systemic blood pressure.

Aims: The purpose of this study was to construct new reference range for fetal middle cerebral artery peak systolic velocity (MCA-PSV) in uncomplicated pregnancy at 19-40 weeks of gestation. Methods: This was a prospective cross-sectional study involving 400 singleton pregnancies between 19 and 40 weeks of gestation without any known risk factors of adverse pregnancy outcome who were referred for routine obstetric examination. The protocol included the doppler examination of fetal middle cerebral artery (MCA) within 2 mm after its origin from the internal carotid artery and data were used to construct the normograms and percentile fitted curves of each doppler parameter for different gestational age. Results: Among 400 singleton uncomplicated pregnancies between 19 and 40 weeks of gestation maximum number of pregnancies (10%) was at 19 weeks of gestation and minimum (2.5%) was at 31 weeks. The fetal peak systolic blood flow in the MCA showed significant correlation with period of gestation. Mean MCA-PSV was 22.35 ± 3.05 at 19 weeks of gestation which increased to 67.73 ± 9.92 at 40 weeks. The MCA-PSV showed continuous increment with increasing gestational age.Conclusions: Continuous increment in the peak systolic volume with advancing gestational age was obtained which was consistent with the previous studies done by various authors. The percentile fitted values and normograms will be valuable for the serial measurement of the peak systolic volume of the middle cerebral artery for complicated pregnancies.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 42-45 DOI: http://dx.doi.org/10.3126/njog.v8i2.9769
