ABSTRACT
Introduction@#Health care workers of First Central Hospital of Mongolia have vaccinated with three different vaccines against SARS-CoV-2. We detected SARS-CoV-2 N and S-RBD antibodies after 30-90 days of second dose of vaccination. @*Method@#Quantitation of antibodies to the spike protein of SARS-CoV-2 was performed for the detection of adaptive immune response in 291 HCWs vaccinated with Covishield, Sinopharm and Pfizer Biontech. Detection and quantitation of SARS-CoV-2 N and S antibodies were performed by the electrochemiluminesce assay Cobas e411, Roche. @*Result@#SARS-CoV-2-S-RBD IgG titer were negative 0%, weak positive 0.4%, positive 17.5%, strong positive 82.1% of 246 HCWs vaccinated with Covishield and were negative 2.8%, weak positive 8.5%, positive 57.1%, strong positive 31.4% of 35 HCWs vaccinated with Sinopharm. </br> In all HCWs vaccinated with Pfizer Biontech SARS-CoV-2-S-RBD IgG titers were strong positive. @*Conclusion@#Humoral immunity was produced in HCWs after two doses of Covishield vaccine 100%, Sinopharm 97.0%, Pfizer Biontech 100% respectively. Antibody titer was higher among younger age workers.
ABSTRACT
Introduction @#In the last years other country scientists told about not only determine infant weights, need to interest correlation between maternal weight, height and infant weight. In our country few research articles posted about anthropometry of obstetrics and gynecology. Our study aim is determine maternal weight, infant weight, placenta weight and assess factors affecting roles on maternal story of “Amgalan” Maternity Hospital in 2014-2015.@*Goal@#The current study aimed at assessing maternal weight, infant weight, placenta weight and evaluating the effect of factors leading to it. @*Materials and Methods@#The data was already collected from “Amgalan” Maternity Hospital using maternal history and record and it was collected measuring general physical characteristics such as body weight and height, infant weight, placenta weight and body circumferences. We used retrospective method and collected statistical data was analyzed using SPSS 21.0 software. @*Results@#Of total 964 study participants aged 18-45. The average age of participants was 29.6 ± 5.8 years old and 49.7% (n=479) was working during pregnancy, 45.7% (n=441) hadn’t works, 4.6% (n=44) was student. The average weight of mothers was 75.4±11.5, weight of infants was 3439.5±456, weight of placenta was 685±129. The following factors affected maternal and infant weights: lower education, working, early and late pregnancy complication. Maternal weight had a low direct correlation with infant weight (r=0.267, p<0.01) and placenta weight (r=0.208, p<0.01). In our study maternal height had a low direct correlation with infant weight(r=0.173, p<0.01) and infant weight had a moderate direct correlation with placenta weight (r=0.376, p<0.01). @*Conclusions@#</br> 1. The average maternal weight was 75.4±11.5, infant weight was 3539.5±456, placenta weight was 685±129. </br> 2. The following factors affected maternal and infant weights: lower education, working status, early and late pregnancy complications. </br> 3. Maternal weight had a little direct correlation with infant weight (r=0.267, p<0.01) and placenta weight (r=0.208, p<0.01).
