Filter by:The QRS-T angle represents a novel marker of myocardial repolarisation. It is defined as the angle difference between the direction of ventricular depolarisation (QRS wave) and the direction of ventricular repolarisation (T wave). It is an indicator of instability in the electrophysiological properties of the myocardium and is associated with arrhythmias. The frontal QRS-T angle is a straightforward, cost-effective parameter that can be readily obtained from 12-lead electrocardiography. The most prevalent arrhythmias during pregnancy are atrial arrhythmias. However, ventricular tachyarrhythmias are exceedingly rare during pregnancy and may be life-threatening. Caesarean section is one of the most common surgical procedures. General anaesthesia, spinal anaesthesia and epidural anaesthesia can be employed in these patients. Spinal anaesthesia is a frequently employed method in caesarean section operations due to its rapid onset of effect, technical simplicity of application and higher probability of success. In pregnant women, anaemia is defined as a haemoglobin concentration below 11 mg/dL in the first trimester, 11 mg/dL in the second trimester and 10.5 mg/dL in the third trimester.
The purpose of this study is to compare maternal outcomes such as increased hemoglobin need for blood transfusion and hemoglobin level before and post partum in women with hemoglobin <9 gr/dl , treated with venofer and women treated with ferinject.
Anemia is a common problem during pregnancy. Most studies have demonstrated that anemia during pregnancy have adverse effects on their pregnancy outcome, which is important and should pay attention to prevent and solve such problems. The most common cause of anemia is iron deficiency. Several studies reveal that Vitamin C promotes iron absorption. In this study we will compare between Vitamin C with iron supplement and iron supplement alone in prevention of anemia in pregnancy.
Background Blood transfusions in pregnancy are usually urgent, unpredictable, and occur in otherwise healthy women. There is evidence of increasing rates of maternal red blood cell (RBC) transfusion around childbirth both in Europe and in US. Indeed, they are recorded in approximately 0.4-1.6% of all deliveries. Although obstetric patients use a small proportion of the blood supply overall (3-4%), however over the last years there has been a significant increase (about 30%) in the use of blood and blood products throughout pregnancy. Most available data relate to the peri-partum period, defined as those occurring from 48 hours before delivery onwards. Anemia in pregnancy is associated with increased maternal mortality and fetal intrauterine growth restriction (IUGR). The risk of these adverse effects is proportional to the severity of anemia; for instance, preterm birth and low birth weight rates are particularly high among women with a hemoglobin below 7 g/dL. The presence of anemia in at-term pregnant women is a rather frequent and unrecognized risk factor for peri-partum hemorrhage (PPH) transfusion. In a retrospective investigation, we have calculated that almost 20% of at-term pregnant women show iron deficiency anemia. It has been suggested that reduction of RBC transfusion in the context of PPH may decrease maternal mortality and, at the same time, reduce costs. Patient's Blood Management (PBM) is a well-known strategy based on 1) identification of anemia; 2) reduction of blood loss and 3) reduction of RBC transfusion. In several medical specialties, recommendations based on available evidence highlighted the concept that a restrictive RBC administration is safe and efficacious. Despite the fact that the WHO has recommended PBM early 2010, the majority of hospitals are in need of guidelines to apply PBM in daily practice. Rationale Anemia is a frequent and often unrecognized hallmark of at-term pregnancies. Systematic collection of data on transfusion practice during pregnancy and post-partum period are scarce. The application of PBM in obstetrics is expected to improve pregnancy outcome and optimize resources. Objectives Objectives of the present study are 1. To estimate: frequency of anemia in pregnancy and feto-maternal complications, distribution of haemorrhage aetiologies and transfusion indications. 2. To evaluate associations of these outcomes with gestational age, and transfusion dose.
Anemia is a common pregnancy condition that has multiple origins. Its frequency and severity seem to be increasing, despite the existing management recommendations and the awareness of health professionals. The objective of this study is to make a statement of this pathology within our establishment, to evaluate the proportion of patients presenting this pathology and to highlight possible risk factors.
Maternal iron deficiency anemia is associated with maternal and infant mortality, spontaneous preterm birth, maternal postpartum hemorrhage, and neurocognitive defects in the neonate. Therefore, preventing maternal iron deficiency anemia in at-risk women is critical. Obese pregnant women have greater systemic inflammation and circulating hepcidin levels compared to nonobese pregnant women. This phenotype implies obese pregnant women have decreased iron bioavailability and may be less responsive to oral iron supplementation because hepcidin is a negative regulator of dietary iron absorption, suggesting alternative interventions are needed to optimize their iron status in pregnancy. There is increasing evidence that consuming the oral bovine lactoferrin (bLf) can enhance dietary iron absorption by promoting an anti-inflammatory immune response and hepcidin suppression, indicating this intervention may be beneficial to pregnant obese women at risk for iron deficiency anemia. The primary goal of this study is to test the feasibility and acceptability of this low-cost, safe, innovative approach to optimizing maternal iron status in obese women at risk of iron deficiency anemia (Hb 11.0 - 12.0 g/dL (first trimester)/10.5 - 11.5 g/dL (second trimester) for non-Black women and 10.2 - 11.2 g/dL (first trimester)/9.7 -- 10.7 g/dL (second trimester) for Black women) from 15-20 weeks of gestation (WG) until the time of labor. The investigators will explore effects on maternal and neonatal iron status and Hb and changes to maternal systemic inflammation and circulating hepcidin. This study is an essential first step toward evaluating if daily oral bLf is an efficacious, safe, inexpensive, and scalable clinical strategy for the prevention of maternal iron deficiency anemia and its related complications in at-risk women.
Erythroferrone (ERFE) is a recently identified iron-regulatory hormone that couples iron homeostasis to erythropoiesis but at this time there are no human data on this hormone in pregnant women and their neonates. The investigators hypothesize that ERFE is a sensitive biomarker of iron deficiency and anemia in pregnancy and neonates, and that it mediates the feedback mechanism to correct iron deficiency and anemia. To address this research gap, the investigators will measure ERFE in maternal serum, umbilical cord serum and placental tissue using an existing biospecimen archive.
According to the World Health Organization (WHO), anemia is the most common disease, affecting >1.5 billion people worldwide. Furthermore, iron deficiency anemia (IDA) accounts for 50% of cases of anemia. IDA is common during pregnancy and the postpartum period, and can lead to serious maternal and fetal complications. Measurement of serum ferritin has the highest sensitivity and specificity for diagnosis of IDA unless there is a concurrent inflammatory condition. The lower threshold value for hemoglobin (Hb) in pregnant women is <11 g/dL during the 1st and 3rd trimesters, and <10.5 g/dL during the 2nd trimester. In postpartum period a Hb concentration <10 g/dL indicates clinically significant anemia. Oral iron therapy is given as the first-line treatment for IDA.
Pregnancy is associated with increased requirements for iron and increased blood volume of up to 40%. Because expansion in plasma volume is higher than the increase in the mass of red blood cells, there is a fall in hemoglobin concentration, which leads to physiological anemia, characterized with lower hemoglobin (Hb), hematocrit and red blood cells, but without changes in mean corpuscular volume (MCV). Anemia in pregnancy is defined with Hb values under 110 g/L in the first trimester and under 105 g/L in the second and third trimester. Iron deficiency is thought to be the most common nutrient deficiency among pregnant women. Consequences of anemia include delayed fetal growth, premature delivery, intrauterine fetal death, postpartum depression and delayed psychomotor development of a child. It is known that in women that are not anemic daily iron supplementation of 27 mg/day is sufficient, which can be obtained from adequate nutrition or body supplies. Iron supplementation is pregnancy has been recommended by the WHO (World Health Organisation) since 1959, and this recommendation was confirmed by numerous professional associations. However, in women with anemia, or women subjected to particular dietary regimens with diminished quantity of iron, including vegetarian or vegan diet, required supplementation dosage is higher, and estimated in the literature to be 120 mg/day. The aim of this study was to analyze whether adding vitamin B12 (5 µg /100 days), along with folic acid and iron as supplement in pregnant women who are not anemic and who need only iron supplementation, will result in improvements of hematological and biochemical markers.
Anemia during pregnancy occurs in 41% of women. The most common etiology is iron deficiency, but studies to determine prevalence of other causes of anemia in pregnancy are still lacking. However, anemia in pregnancy lead to adverse pregnancy outcomes and increase risk of maternal and fœtal morbidity and mortality. Specific management of anemia is so needed.
