Hypertensive Disorder Of Pregnancy

Objective: The present study aimed at assessing the association between environmental temperature and the relative humidity of the air with frequency of hypertensive disorders of pregnancy. Methods: A prospective and retrospective, descriptive, ecological study was held at a teaching maternity in Recife, Brazil. Data from all 26.125 pregnant women admitted between 2000 and 2006 were analysed and 5.051 had the diagnosis of hypertensive disorder of pregnancy. The incidence percentages were calculated monthly per deliveries. Data on mean monthly temperature and relative humidity of the air were collected and monthly comparisons were conducted. February was chosen as the reference month due to its lowest incidence of the disease. The relative chance of hypertensive disorders of pregnancy for each other month was estimated by odds ratio and Pearson's correlation coefficient was used to calculate the relation between the incidence of hypertensive disorders of pregnancy and the mean monthly temperature and relative air humidity. Results: February presented the lowest mean monthly incidence (9.95%) and August the highest (21.54%). Pearson correlation coefficient revealed a higher incidence of hypertensive disorders of pregnancy in the cooler months (r= -0.26; p=0.046) and no significant effect of relative air humidity (r=0.20; p=0.128). Conclusion: The incidence of hypertensive disorders of pregnancy may be affected by variations in temperature, increasing during cooler periods.

Abstract Purpose: To evaluate the association of hypertensive disorders of pregnancy with SARs-CoV-2 infection in pregnant women.Methods: We conducted a retrospective cohort study of all pregnant patients with positive SARs-CoV-2 molecular test at four participating hospitals located in a large metropolitan city and who delivered between February 1st and November 24th, 2020. Patients who tested positive during their pregnancy and delivered (index cases) were compared to the three subsequent deliveries of patients who tested negative (controls) at the same institution. We evaluated the impact of COVID-19 on the development of hypertensive disorders of pregnancy.Results: A total of 280 patients were included in the study: 70 patients who tested positive for Coronavirus Disease-2019 and 210 matched controls. Compared with pregnancies negative for SARS-CoV-2 infection, COVID-19 was associated with an increased risk of developing a hypertensive disorders of pregnancy (OR 3.68, 95% CI 1.67 -8.10). Overall rates of preeclampsia with severe features were significantly higher in patients with a COVID-19 diagnosis (18.6% vs 7.1%, p=0.006). Of COVID-19 positive patients, an early SARS-CoV-2 infection (prior to 32 week’s gestation) conferred a higher risk of hypertensive disorders in pregnancy (OR=6.29, CI 1.64-24.07; p=0.007). There was no difference in route of delivery, preterm birth, intrauterine growth restriction, intrauterine fetal demise, or pregnancy and fetal outcomes.Conclusion: COVID-19 is a risk factor for hypertensive disorders of pregnancy.Tweetable AbstractPatients who test positive for COVID-19 during their pregnancy are at increased risk of developing a hypertensive disorder of pregnancy compared to pregnant patients who test negative for COVID-19. Earlier SARs-CoV-2 infection results in increased risk of developing a hypertensive disorder. Furthermore, even patients who are asymptomatic but positive for SARs-CoV-2 during their pregnancy have a higher risk of developing a hypertensive disorder of pregnancy.

Objective The study aimed to examine the incidence of hypertensive disorders of pregnancy in women diagnosed with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2, also known as COVID-19). Study Design This was a retrospective cohort study of all women who delivered at MedStar Washington Hospital Center in Washington, DC from April 8, 2020 to July 31, 2020. Starting April 8, 2020, universal testing for COVID-19 infection was initiated for all women admitted to labor and delivery. Women who declined universal testing were excluded. Hypertensive disorders of pregnancy were diagnosed based on American College of Obstetricians and Gynecologists Task Force definitions.1 Maternal demographics, clinical characteristics, and labor and delivery outcomes were examined. Neonatal outcomes were also collected. Laboratory values from admission were evaluated. Our primary outcome was the incidence of hypertensive disorders of pregnancy among women who tested positive for COVID-19. The incidence of hypertensive disorders of pregnancy was compared between women who tested positive for COVID-19 and women who tested negative. Results Of the 1,008 women included in the analysis, 73 (7.2%) women tested positive for COVID-19, of which 12 (16.4%) were symptomatic at the time of admission. The incidence of hypertensive disorders of pregnancy was 34.2% among women who tested positive for COVID-19 and 22.9% women who tested negative for COVID-19 (p = 0.03). After adjusting for race, antenatal aspirin use, chronic hypertension, and body mass index >30, the risk of developing any hypertensive disorder of pregnancy was not statistically significant (odds ratio: 1.58 [0.91–2.76]). Conclusion After adjusting for potential confounders, the risk of developing a hypertensive disorder of pregnancy in women who tested positive for COVID-19 compared with women who tested negative for COVID-19 was not significantly different.

Introduction: Black women experience significant maternal mortality (3.3 times higher) compared to White women, and experience higher adverse outcomes. In the United States, cardiovascular disease is the second leading cause of maternal mortality for Black women. Hypertensive disorders of pregnancy (HDOP) falls under the cardiovascular disease spectrum. Objective: To explore differences in women diagnosed with a HDOP compared to those that do not have HDOP. Methods: A total of 226 African American women from Metro-Detroit and Columbus, Ohio enrolled in a cross-sectional study who had recently gave birth. Women enrolled in a mixed methods study on social and biological stressors to preterm birth with a completed medical record abstraction were identified as having chronic hypertension or a hypertensive disorder of pregnancy (HDOP) prior to the current pregnancy. HDOP is defined as chronic hypertension, chronic hypertension with superimposed preeclampsia, gestational hypertension, preeclampsia or eclampsia. Perinatal complications and birth outcomes were explored. Sociodemographic was derived from completed prenatal questionnaires. Chi square was used for categorical variable and T-test was used for continuous variables. Significance is defined as p ≤ 0.05. Results: The mean age was 26.8±5.9 years. Approximately 70.4% (n=159) were from Detroit, MI and 29.6% were from Columbus, OH. The mean previous live births were 1.9±1.8 (range 0-8). The average number of prenatal visits with a physician were 9.2±2.9 (range 2-19) and the total number of any prenatal visits were 16.0±6.9 (range 1-44). Average baby gestational age is 37.9±2.2 weeks (range 15-26 weeks), and weight is 2998±703.4 grams. Approximately 60 women (26.5%) were identified with a hypertensive disorder of pregnancy. Compared to women not diagnosed with a HDOP, women with a HDOP had an older mean age (28.3±6.4 vs 26.3±5.6), p=0.023; had more prenatal visits (18.2±7.6 vs 15.6±6.5) p=0.007; had babies at a younger gestational age (37.2±2.1 vs 38.2±2.1), p=0.002. Conclusion: These findings will aid in determining factors associated with HDOP in our population, and aid in determining next steps to reduce historic mortality in this group.

Objective: To determine the prevalence and outcome of hypertensive disorder of pregnancy in Babcock University Teaching Hospital, Ilishan-Remo, Ogun State Nigeria Method: This was a retrospective descriptive study of all documented cases of hypertensive disorder of pregnancy between the 1st of June 2012 and 31st May, 2017. Information such as age, parity, booking status, level of education, blood pressure at presentation, urinalysis at presentation, gestational age at presentation, and delivery, mode of delivery, baby’s birth weight was extracted from patients’ case files. Result: There were 1,118 deliveries during the study period out of which 55 (4.9%) patients had hypertensive disorders in pregnancy. The mean age was 31.5years ±48.1 and mean parity, 1.2± 1.1.  The mean systolic and diastolic blood pressures were 180.4 ± 1.88mmHg and 105.1± 1.5mmHg, respectively. Thirty-four (75.5%) of the women had preeclampsia/ eclampsia, while 7 (15.5%) had gestational hypertension. Most women were delivered preterm (22 patients, 48.7%).  The majority of them (33, 73.3%) were delivered by cesarean section, out of which 2 (4.4%) were elective cesarean section and 31 patients (68.8%) were emergency cesarean section. The case fatality rate was 1.8%. Conclusion: Pre-eclampsia was the most prevalent t hypertensive disorder of pregnancy.  It was more prevalent among primigravidae patients and the most common complication was preterm delivery. Strengthening antenatal care services will enable early identification of cases. Prompt referral of cases for specialist care will help in reducing the adverse outcomes associated with the condition.

Hypertensive Disorders

Hypertensive disorders are the most common medical complications of pregnancy and a major cause of maternal and perinatal morbidity and death. The detection of elevated blood pressure during pregnancy is one of the cardinal aspects of optimal antenatal care. With the outbreak of novel coronavirus disease 2019 (COVID-19) and the risk for person-to-person spread of the virus, there is a desire to minimize unnecessary visits to health care facilities. Women should be classified as low risk or high risk for hypertensive disorders of pregnancy and adjustments can be accordingly made in the frequency of maternal and fetal surveillance. During this pandemic, all pregnant women should be encouraged to obtain a sphygmomanometer. Patients monitored for hypertension as an outpatient should receive written instructions on the important signs and symptoms of disease progression and provided contact information to report the development of any concern for change in status. As the clinical management of gestational hypertension and preeclampsia is the same, assessment of urinary protein is unnecessary in the management once a diagnosis of a hypertensive disorder of pregnancy is made. Pregnant women with suspected hypertensive disorders of pregnancy and signs and symptoms associated with the severe end of the disease spectrum (e.g., headaches, visual symptoms, epigastric pain, and pulmonary edema) should have an evaluation including complete blood count, serum creatinine level, and liver transaminases (aspartate aminotransferase and alanine aminotransferase). Further, if there is any evidence of disease progression or if acute severe hypertension develops, prompt hospitalization is suggested. Current guidelines from the American College of Obstetricians and Gynecologists (ACOG) and The Society for Maternal-Fetal Medicine (SMFM) for management of preeclampsia with severe features suggest delivery after 34 0/7 weeks of gestation. With the outbreak of COVID-19, however, adjustments to this algorithm should be considered including delivery by 30 0/7 weeks of gestation in the setting of preeclampsia with severe features.

Pooled Prevalence

Abstract Background Hypertensive disorders of pregnancy complicate around 6% of pregnancies and accounts for 19% of maternal death in Ethiopia. The current review aimed to assess maternal and perinatal outcomes of pregnancies complicated by hypertension in Ethiopia. Methods A systematic review and meta-analysis was done on the outcome of hypertensive disorder among pregnant women in Ethiopia. Literature search was made in five databases and Statistical analyses were carried out by using Stata 14 software. The pooled prevalence of maternal death, HELLP syndrome, perinatal death, and low birth weight was calculated using a random-effects model. Egger’s test and funnel plot were used to evaluate publication bias. The Cochran Q test and I2 test statistics were used to test the heterogeneity of studies. Result Thirteen studies included in the review, with an overall sample size of 5894 women diagnosed to have hypertensive disorder of pregnancy. The pooled prevalence of maternal death was estimated to be 4% (95% CI: 2, 6%). The pooled prevalence of HELLP syndrome was 13% (95% CI: 10, 16%). Other complications such as pulmonary edema, kidney injury, hepatic injury, placental abruption, and aspiration pneumonia were also reported. Perinatal death was observed in one-fourth of women with HDP 25% (95% CI: 18, 32%). The pooled prevalence of low birth weight neonate in a woman with HDP is 37% (95% CI, 27, 48%). Conclusions In Ethiopia, the prevalence of perinatal and maternal mortality among pregnant women with one of the hypertensive disorders were found to be higher than rates reported from high income as well as most of the low and middle income countries. For instance, one in four of pregnancies complicated by hypertensive disorder end up in perinatal death in Ethiopia. HELLP syndrome, placental abruption, pulmonary edema, renal damage, prematurity, perinatal asphyxia, and low birth weight were also commonly reported. To improve the health outcomes of hypertensive disorders of pregnancy, it is recommended to improve utilization of maternal health service; early detection and early referral of pregnant women with hypertensive disorder; advocating policies and strategies that improves the quality of health care that a pregnant woman and her newborn receive.

Air Ion Concentration

When using electro-ionizers in the conditions of the fruit storage facilities, it is necessary to take into account the influence of environmental conditions of the electrical ionizers. A particularly important factor here is the relative humidity of the air in the storage tanks. At higher values of the relative humidity of air in the atmosphere of the fruit storage, air ion combine with water molecules to form heavy ions, as a result of which the volume concentration of ions decreases. To test these theoretical assumptions, we conducted studies of the operating parameters of the ionizer under condition of storage tanks high relative air humidity. Studies have shown that under conditions of high air humidity the concentration of ion decreases by 10–12% and at a distance of 1 meter from the ionizer, the air ion concentration is 1,6∙1013 ion/m3.

Hypertensive disorders of pregnancy, including pre-eclampsia, are a significant and commonly encountered group of medical disorders of pregnancy. A primary care clinician is ideally placed to screen for, diagnose and, if confident, initiate management in antenatal and postnatal women. Early involvement of maternity services is advised if a hypertensive disorder in pregnancy is suspected or diagnosed. Checking of maternal blood pressure and urinalysis should be encouraged during all routine appointments with pregnant women. The aim of this article is to provide an overview of the hypertensive disorders of pregnancy, their diagnosis and management in primary care, with a review of commonly used antihypertensive agents in current UK clinical practice.
