Hemoglobin Testing in Pregnant Patients

The project is a prospective observational study aimed to assess and to validate the use of point-of-care hemoglobin testing in pregnancy. Point-of-care hemoglobin testing has the potential to (1) increase access to hemoglobin monitoring in pregnancy in low resource settings, (2) increase availability of hemoglobin monitoring in anemic patients, and (3) provide immediate results for real-time patient counseling and intervention. However, to date, point-of-care hemoglobin testing devices have not yet been studied for use in an ambulatory obstetric population. The Masimo device is a Root Radical 7 Pulse CO-Oximeter, manufactured by Masimo, Inc. This device is non-invasive and placed externally on a patient's finger to generate an estimation of a patient's hemoglobin value. The HemoCue® device is a minimally-invasive device that relies on the finger prick method to get a capillary hemoglobin measurement, and The Rubby is a mobile application based platform that uses a photo of the participants nailbed to estimate hemoglobin values. Participants in this study will be approached at the Obstetrics and Gynecology clinics at George Washington Medical Faculty Associates. Point-of-care hemoglobin measurements will be assessed using the non-invasive Masimo device along with minimally-invasive hemoglobin HemoCue® Hb 801 device and compared to traditional venipuncture hemoglobin testing.

BEP Supplementation Research in Bangladesh (JiVitA-BEP-IR)

The primary aim of the study is to evaluate the effect of fortified balanced energy and protein (BEP) supplementation vs. control (multiple micronutrient supplement, MMS) without targeting and with targeting (either by low prepregnancy BMI or low prepregnancy BMI and inadequate gestational weight gain) on birth weight and adverse birth outcomes of low birth weight (LBW \< 2500 g) and small-for-gestational age (SGA). To do this we are proposing a cluster-randomized, open labeled effectiveness trial with four arms The main question\[s\] it aims to answer are: • Does mean birth weight and rate of LBW and SGA differ among mothers randomized to four arms that include targeted or untargeted BEP supplementation vs. MMS differ. Participants will be recruited in early pregnancy and be enrolled in the trial and randomly receive: 1. A daily BEP supplement from enrollment until birth 2. A daily BEP supplement from enrollment until birth, if they have low pre-pregnancy BMI with the rest receiving a MMS supplement 3. A daily BEP supplement from enrollment until birth, if they have low pre-pregnancy BMI with the rest receiving a MMS supplement or get switched to a BEP supplement based on inadequate gestational weight gain. Researchers will compare the above groups to women receiving a MMS daily to see if birth weight is higher in the intervention arms. Other adverse outcomes such as low birth weight, small-for-gestational age and preterm birth will also be compared between groups and relative to the control.

Early Antenatal Support for Iron Deficiency Anemia

This is a randomized, controlled multi-site trial of iron therapy in pregnancy. The purpose of this research is to see if second trimester initiation of intravenous (IV) iron therapy is better than oral iron therapy for treatment of anemia in pregnancy by improving blood count, quality of life and reducing side effects.

Liposomal Iron 30 mg Supplement in Non-anemic Pregnant Females

Protocol Summary: Liposomal Iron Supplementation in Non-anemic Pregnant Females This observational study aims to evaluate the efficacy and safety of daily liposomal iron supplementation (30 mg) in non-anemic pregnant women during their second trimester of pregnancy. The study will focus on pregnant females aged 18-45 years with low-risk, singleton pregnancies who are non-anemic (hemoglobin ≥10.5) at 14-16 weeks gestation. Primary Research Question: Does daily supplementation with 30 mg liposomal iron effectively maintain maternal hemoglobin levels over 90 days? Measured by: The difference in maternal hemoglobin levels between baseline and after 90 days of treatment in women recruited at 14-16 weeks gestation. Secondary Research Questions: What are the effects of liposomal iron supplementation on serum ferritin levels? Measured by: Changes in serum ferritin levels between baseline and after 90 days of treatment. What is the safety profile of liposomal iron supplementation during pregnancy? Measured by: Maternal gastrointestinal side effects monitored at each prenatal visit (day 30, 60, and 90). What is the compliance rate with liposomal iron supplementation? Measured by: Participant-reported compliance assessed at each prenatal visit (day 30, 60, and 90). Participants will: Receive daily liposomal iron supplementation (30 mg) for 90 days. Attend regular prenatal visits for monitoring at days 30, 60, and 90. Complete questionnaires about compliance and any adverse effects at each visit. Undergo blood tests to measure hemoglobin and serum ferritin levels at baseline and day 90. This multi-center study will involve 714 participants across 100 sites, with recruitment beginning in November 2024 and study completion expected by July 2025. The study's findings will contribute to understanding the role of liposomal iron supplementation in preventing iron deficiency during pregnancy and its potential advantages over traditional iron supplements in terms of tolerability and compliance.
