Abstract Objective: We conducted a meta-analysis of randomized clinical trials evaluating the clinical effects of ferric carboxymaltose therapy compared to other intravenous iron in improving hemoglobin and serum ferritin in pregnant women. We also assessed the safety of ferric carboxymaltose vs. other intravenous iron. Data source: EMBASE, PubMed, and Web of Science were searched for trials related to ferric carboxymaltose in pregnant women, published between 2005 and 2021. We also reviewed articles from google scholar. The keywords "ferric carboxymaltose," "FCM," "intravenous," "randomized," "pregnancy," "quality of life," and "neonatal outcomes" were used to search the literature. The search was limited to pregnant women. Selection of studies: Studies related to ferric carboxymaltose in pregnancy were scanned. Observational studies, review articles, and case reports were excluded. Randomized studies in pregnant women involving ferric carboxymaltose and other intravenous iron formulations were shortlisted. Of 256 studies, nine randomized control trials were selected. Data collection: Two reviewers independently extracted data from nine selected trials Data synthesis: The final effect size for increase in hemoglobin after treatment was significant for ferric carboxymaltose vs. iron sucrose/iron polymaltose (standard mean difference 0.89g/dl [95% confidence interval 0.27,1.51]). The final effect size for the increase in ferritin after treatment was more for ferric carboxymaltose vs. iron sucrose/iron polymaltose (standard mean difference 22.53µg/L [-7.26, 52.33]). No serious adverse events were reported with ferric carboxymaltose or other intravenous iron. Conclusion: Ferric carboxymaltose demonstrated better efficacy than other intravenous iron in increasing hemoglobin and ferritin levels in treating iron deficiency anemia in pregnant women.

Background & objectives: Number of metastatic lymph nodes has a strong prognostic value in the course of breast cancer treatment, morbidity and mortality. This study was undertaken to determine the association between axillary lymph node metastasis and several variables such as age, tumour size, grade, lymphovascular invasion, oestrogen and progesterone receptor expression and HER2/neu status in patients with breast cancer. Methods: In this study 426 (with complete information on study variables) patients with breast cancer on treatment during March 2010 to December 2013, were analyzed. TNM (tumour node matastasis) staging was evaluated. The histological grading of tumours was done according to modified Bloom-Richardson Grading System. The immunophenotype of the tumour was determined as the expression of oestrogen (ER) and progesterone (PR) receptors and HER2/neu status. Univariate and multivariate analyses were carried out to determine the independent predictors of metastatic lymph node. Results: Among the studied patients, 44.36 per cent (189 of 426) of the patients had nodal metastases. Tumour histology, tumour grade, size and lympho-vascular invasion were related with node positivity. On univariate analysis, age, menopause, hormone receptor status did not relate with the node metastasis. Age, tumour grade, tumour size, lympho-vascular invasion and HER2/neu expression was likely to be associated with the number of lymph node metastasis. Interpretation & conclusions: The lymph node status was associated with clinical stage, tumour grade, tumour histology and HER2/neu status. These factors may be used for better management of such patients.

Objective: Seven to eight days germinated plants of Triticum aestivum (wheat grass) are a rich source of vitamin A, C, calcium, magnesium, phosphorus, potassium, sodium, sulphur, cobalt, zinc and protein. Traditionally the aqueous extract of T. aestivum was reported to be used as a health tonic in folk and ayurvedic medicine. We previously reported that aqueous extract of T. aestivum was found to reduce the blood transfusion requirement in iron overloaded Thalassemia and Myelodysplastic syndrome patients. Our objective was to extract and purify active ingredients from wheat grass and study their mode of action in stabilizing hemoglobin level in those patients. Design and Method: Active ingredients of wheat grass were extracted and purified by cation exchange column chromatography followed by High Performance Liquid Chromatography. In vitro experiments with phenylhydrazine treated red blood cell hemolysate were carried out before and after treatment of purified fraction of T. aestivum to study iron chelating activity. Result: Purified fraction of T. aestivum treated red blood cell showed significant inhibition of free reactive iron production and formation of thio-barbituric acid reactive substances when compared to desferrioxamine treated hemolysate. Conclusion: Iron chelating activity of purified fraction of T. aestivum, an inexpensive, easily available source, is very promising for further clinical trial and development of oral iron chelator drug for Thalassemia, Myelodysplastic syndrome and other iron overloaded diseases.
