Risk Of Preeclampsia

AIM: To investigate blood groups and the other possible risk factors for preeclampsia among Sudanese women.MATERIAL AND METHODS: A case – control study was conducted at Saad Abualila Hospital, Khartoum, Sudan during the period of July 2013 through December 2014. The cases were women with preeclampsia and healthy pregnant women were the controls.RESULTS: Two hundred eighty pregnant women were enrolled (140 in each arm of the study). Around one-quarter of all women (280) were primiparae (74.0, 26.4%), the majority were housewives (201, 71.7%). Seventy-nine (28.2%) were illiterate or had no informal education. Around half of the women (130, 46.4%) had O blood group. Binary logistic regression showed association between preeclampsia and lack of antenatal care (OR = 2.75, 95% CI = 1.172─6.494, P = 0.020) as well as O blood group (OR = 1.78, 95% CI = 1.088─2.934, P=0.022).CONCLUSION: The current study showed that women with blood group O were at higher risk of preeclampsia.

Postpartum hemorrhage (PPH) is a common complication of pregnancy and a global public health concern. Even though PPH risk factors were extensively studied and reported in literature, almost all studies were conducted in non-Asian countries or tertiary care centers. Our study aimed to explore relevant risk factors for PPH among pregnant women who underwent transvaginal delivery at a Thai–Myanmar border community hospital in Northern Thailand. An exploratory nested case-control study was conducted to explore risk factors for PPH. Women who delivered transvaginal births at Maesai hospital from 2014 to 2018 were included. Two PPH definitions were used, which were ≥ 500 mL and 1000 mL of estimated blood loss within 24 h after delivery. Multivariable conditional logistic regression was used to identify significant risk factors for PPH and severe PPH. Of 4774 women with vaginal births, there were 265 (5.55%) PPH cases. Eight factors were identified as independent predictors for PPH and severe PPH: elderly pregnancy, minority groups, nulliparous, previous PPH history, BMI ≥ 35 kg/m2, requiring manual removal of placenta, labor augmentation, and fetal weight > 4000 gm. Apart from clinical factors, particular attention should be given to pregnant women who were minority groups as PPH risk significantly increased in this population.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious complication of acute pulmonary embolism (PE) which remains underdiagnosed. A better understanding of risk factors for CTEPH would improve our ability to predict which PE survivors are at risk. Several medical conditions—including malignancy, splenectomy, thyroid hormone supplementation, the presence of an intravascular device, inflammatory bowel disease, osteomyelitis, and non-O blood group—have been associated with increased risk of CTEPH, primarily in studies comparing patients with CTEPH to individuals with non-thrombotic conditions. Because many of these conditions increase thrombosis risk, it remains unclear whether their association with CTEPH reflects a general effect on thrombosis risk, or a specific effect on the risk of developing CTEPH as an outcome of thrombosis. We performed a case-control study comparing the frequencies of these conditions in patients with CTEPH versus patients with acute PE who did not develop CTEPH. The conditions studied were equally frequent in the CTEPH and PE cohorts, although there was a trend towards an increased frequency of splenectomy and non-O blood group among the CTEPH cohort. Thus, other than the possible exceptions of splenectomy and non-O blood group, the investigated medical conditions do not appear likely to increase the risk of CTEPH as an outcome of acute PE, and thus are unlikely to be useful in predicting CTEPH risk among PE survivors.

AbstractIn Fall 1981, an outbreak of acute infectious conjunctivitis with keratitis (EKC) occurred in patients who had visited a private ophthalmology clinic just prior to onset of illness. Among an estimated 2,200 patient visits to the office from August 10 to October 15, 1981 for problems unrelated to infectious conjunctivitis, 39 (1.8%) persons subsequently developed EKC. The median incubation period was 6.5 days (range, 1 to 14 days). A case-control study was done to identify risk factors associated with contracting EKC; patients with EKC were more likely than control patients to have been examined by one or the other of two of the four ophthalmologists at the clinic and to have undergone procedures such as tonometry or foreign body removal. Adenovirus was isolated from conjunctival swabs from four of five persons with conjunctivitis; three were type 8 and one was type 7. Recognition of the problem and improved handwashing practices were associated with terminating the outbreak. This outbreak illustrates the potential for transmission of adenovirus infection during the provision of eye care. Infection control practitioners should be familiar with measures for the prevention of such infections among ophthalmology patients.

Risk Of Preeclampsia

AIM: Preeclampsia (PE) is a major cause of maternal and neonatal morbidity and mortality. There is a genetic component in the development of PE with estimated heritability around 0.47. Several studies have investigated the association between maternal ABO blood groups (OMIM: 110300) and risk of PE, with contradictory results have emerged. Considering that there is no study in this filed from Iranian population, the present case-control study was carried out at Shiraz (south-west Iran).MATERIAL AND METHODS: In this study 331 women; 121 pregnant with PE and 210 normotensive pregnant women were included. Using blood group O (for ABO blood groups) or Rh+ (for Rh blood groups) as a reference, odds ratios (ORs) and its 95% confidence intervals (95% CI) of PE risk were estimated from logistic regression analysis.RESULTS: Although the A (OR = 0.67, 95% CI = 0.39-1.17, P = 0.165), B (OR = 0.86, 95% CI = 0.48-1.53, P = 0.615) and AB (OR = 1.14, 95% CI = 0.37-3.45, P = 0.812) phenotypes showed lower risks compared with the O blood group, statistical analysis indicated that there was no significant association between ABO phenotypes and risk of PE. The frequency of Rh- phenotype was higher among PE patients compared with the control group. However, the association was not significant (OR = 1.79, 95% CI = 0.69-4.65, P = 0.229). Adjusted ORs for age of participants and parity did not change the above-mentioned associations.CONCLUSION: Our present findings indicate that there is no association between ABO and Rh blood groups and risk of PE in Iranian population.

Introduction: Pregnancy is a normal physiological event but some pregnancyspecific or other medical conditions can cause maternal as well as fetal morbidities and evenmortalities. Among them, raised blood pressure during pregnancy adversely affects bothmaternal and fetal outcomes. Objectives: In this study, risk factors associated with hypertensivedisorders of pregnancy are explored and pregnancy outcomes of hypertensive women withnormotensive pregnant women are compared. Design: Case control study. Settings: Obstetricsand gynecology department of Jinnah hospital Lahore. Period: 1st October 2011 to 24 February2012. Subjects and methods: The case control study of 250 cases (pregnant females withhypertensive disorders) and controls (pregnant females without hypertensive disorder),presented at obstetrics & gynecology department of Jinnah hospital during 1st October 2011 to24 February 2012 was conducted. SPSS software (16) and MS excel were used for statisticalanalysis. Results: Mean age for cases and controls was 26.96 ± 5.29yearsand 25.25 ±4.60years, respectively. Age and history of pregnancy was found to be significantly associatedwith hypertensive disorders of pregnancy. Comparison of neonatal outcome between casegroup and control group showed that hypertensive pregnant women were at higher risk of havingadverse pregnancy outcome. Conclusions: Women with hypertension during pregnancy are atincreased risk of having adverse pregnancy outcome as compared to normotensive women andage, history of pregnancy induced hypertension are contributing risk factors for developinghypertension during pregnancy.
