OBJECTIVE To estimate the efficacy and acceptability of medical abortion at 64-70 days from last menstrual period (LMP) and to compare it with the already proven 57-63 days from LMP gestational age range. METHODS This prospective, comparative, open-label trial enrolled 729 women with pregnancies 57-70 days from LMP requesting abortion at six U.S. clinics. Medical abortions were managed with 2...

The authors examined whether early ultrasound dating (≤20 weeks) of gestational age (GA) in small-for-gestational-age (SGA) fetuses may underestimate gestational duration and therefore the incidence of SGA birth. Within a population-based case-control study (May 2002-June 2005) of Iowa SGA births and preterm deliveries identified from birth records (n = 2,709), the authors illustrate a novel me...

Objective: To establish the reference range of fetal NBL for Indian population and study ethnic variation in Nasal Bone Length.Methods: Prospective Observational Cohort Study was conducted at a North tertiary care Hospital fetuses 11-28 weeks. Fetal Length measured mid-sagittal section face using electronic callipers. Gestational age calculated based on Last Menstrual Period (LMP) or first trim...

The first trimester of pregnancy starts with the first day of the last menstrual period (LMP) and continues until the end of the twelfth week. Although, conception normally occurs two weeks after the LMP, the LMP is chosen as the start of the first trimester because it is a recognizable sign for most women. The term menstrual age and gestational age are used interchangeably, but should not be c...

OBJECTIVES The aim of this study was to investigate the potential impact of gestational age (GA) estimation on the basis of the last menstrual period (LMP) in comparison with GA based on ultrasound examination on rates of survival and neonatal morbidity among extremely preterm infants. METHODS The Swedish national registry of infants born extremely preterm (Extremely Preterm Infants in Sweden...

OBJECTIVE This study was undertaken to determine the ability of history taking alone, compared with pregnancy testing, to identify early pregnancies among potential female measles vaccinees. METHODS As part of an institution-wide measles immunization program, 326 female health care workers (HCWs) who denied being pregnant underwent a urine pregnancy test prior to vaccination. RESULTS Of the...

To study the genetic relationship between the lifetime milk production (LMP), first lactation milk yield (MY305), and length of productive life (PL) in the Slovenian Brown cattle population, first lactation records from 14,389 cows and lifetime performance records (LMP and PL) from 12,416 cows were used. Records of LMP and PL were normalised using the square root transformation of the raw value...

Ninety-four women attending a family planning clinic for emergency contraception (EC) were asked how certain they were of the date of their last menstrual period (LMP), of the timing of intercourse, and how many times in the cycle they had had sex. Urinary pregnanediol concentrations were analyzed in 64 women to assess whether they had ovulated before they used EC. Forty-five women were certain...

Epstein-Barr virus (EBV) latent membrane protein 1 (LMP-1) is the principal oncogenic protein in the EBV transformation process. LMP-1 induces the expression of interferon regulatory factor 7 (IRF-7) and activates IRF-7 protein by phosphorylation and nuclear translocation. LMP-1 is an integral membrane protein with two regions in its C terminus that initiate signaling processes, the C-terminal ...
