A Study on the Correlation of Body Mass Management During Pregnancy with Adverse Pregnancy Outcomes and Labor Progression

Objective:To investigate the effects of body mass management during pregnancy on adverse pregnancy outcomes,duration of labor,and neonatal birth weight.Methods:472 pregnant women who visited Beijing Anzhen Hospital from January to December 2023 were selected,and the pregnant women were divided into 236 each in the observation group and the control group.Body mass of pregnant women was measured and BMI was calculated in early and late pregnancy respectively,and the pregnant women in the control group were guided by routine management,while the observation group was guided by body mass management during pregnancy.The growth of maternal body mass,mode of delivery,postpartum hemorrhage,neonatal score,neonatal blood glucose at birth,and umbilical artery blood,as well as the comparison of the duration of labor,were observed.Results:The observation group was significantly better than the control group in terms of mode of delivery,postpartum hemorrhage,and body mass growth,with statistically significant differences(P<0.05),and there was no statistical significance in terms of neonatal scores,neonatal blood glucose at birth,and umbilical artery blood(P>0.05);the time of the first stage of labor and the time of the second stage of labor of the mothers in the observation group was significantly better than that of the control group,with statistical differences(P<0.05),and the time of the third stage of labor of the mothers in the observation group was statistically better than that of the control group.There was no statistically significant difference between the time of the third stage of labor in the observation group and the control group(P>0.05),and the time of the total stage of labor in the observation group was statistically better than that in the control group(P<0.05).Conclusion:Body mass management during pregnancy can effectively improve maternal control of weight gain,reduce labor time,and decrease the occurrence of adverse pregnancy outcomes.

The role of forensic anthropology in disaster victim identification(DVI):recent developments and future prospects

Forensic anthropological knowledge has been used in disaster victim identification(DVI)for over a century,but over the past decades,there have been a number of disaster events which have seen an increasing role for the forensic anthropologist.The experiences gained from some of the latest DVI operations have provided valuable lessons that have had an effect on the role and perceived value of the forensic anthropologist as part of the team managing the DVI process.This paper provides an overview of the ways in which forensic anthropologists may contribute to DVI with emphasis on how recent experiences and developments in forensic anthropology have augmented these contributions.Consequently,this paper reviews the value of forensic anthropological expertise at the disaster scene and in the mortuary,and discusses the way in which forensic anthropologists may use imaging in DVI efforts.Tissue-sampling strategies for DNA analysis,especially in the case of disasters with a large amount of fragmented remains,are also discussed.Additionally,consideration is given to the identification of survivors;the statistical basis of identification;the challenges related to some specific disaster scenarios;and education and training.Although forensic anthropologists can play a valuable role in different phases of a DVI operation,they never practice in isolation.The DVI process requires a multidisciplinary approach and,therefore,has a close collaboration with a range of forensic specialists.
