Abortion Rate and Contraceptive Practices in Immigrant and Swedish Adolescents

This study, using state data, empirically examines the factors affecting the availability of abortion providers over the period 1992–2011. The empirical results found that the labor force participation of women and the percentage of women of reproductive age in the 18–24 age group were positively associated with the number of abortion providers in a state. The level of antiabortion activities and antiabortion attitudes were negatively associated with the number of abortion providers in a state. Also, a state’s abortion rate was positively associated with the number of abortion providers. The enforcement of a parental involvement law by a state significantly deters physicians or organizations from becoming or remaining abortion providers. JEL Classifications: I11, I18, K32, K38

Art Outcome

Age is perhaps the most important single variable influencing outcome in the assisted reproductive technologies (ART). The effect of advancing age on clinical ART outcome is manifested not only in the pattern of ovarian response to stimulation regimens, but also in reduced implantation efficiency and an increased spontaneous abortion rate. The clinical importance of these factors is compounded by the fact that increasing numbers of older women are presenting for ART treatment. Delayed childbearing is becoming increasingly common in the western world. The availability of methods of birth control, educational and career priorities for women, and the increased rates of divorce and remarriage are some of the factors contributing to this phenomenon.

Recurrent pregnancy loss (RPL) is one of the most common complications of early pregnancy associated in most cases with local or systemic immune abnormalities such as the diminished proportion of regulatory T cells (Tregs). Mesenchymal stem cells (MSCs) have been shown to modulate immune responses by de novo induction and expansion of Tregs. In this study, we analyzed the molecular and cellular mechanisms involved in Treg-associated pregnancy protection following MSCs administration in an abortion-prone mouse mating. In a case-control study, syngeneic abdominal fat-derived MSCs were administered intraperitoneally (i.p) to the DBA/2-mated CBA/J female mice on day 4.5 of pregnancy. Abortion rate, Tregs proportion in spleen and inguinal lymph nodes, and Ho1, Foxp3, Pd1, and Ctla4 genes expression at the feto-maternal interface were then measured on day 13.5 of pregnancy using flow cytometry and quantitative RT- PCR, respectively. The abortion rate in MSCs-treated mice was significantly reduced and normalized to the level observed in normal pregnant animals. We demonstrated a significant induction of Tregs in inguinal lymph nodes but not in the spleen following MSCs administration. Administration of MSCs remarkably upregulated the expression of HO1, Foxp3, Pd1, and Ctla4 genes in both placenta and decidua. Here, we show that MSCs therapy could protect the fetus in the abortion-prone mice through Tregs expansion and up-regulation of Treg-related genes. These events could establish an immune-privileged microenvironment, which participates in regulation of detrimental maternal immune responses against the semi-allogeneic fetus.

Misoprostol Group

Objective: To compare the complete abortion rate, the induction-to-abortion time, and side effects between 600 mcg and 800 mcg misoprostol sublingually. Materials and Methods: Total, of 108 pregnant women with gestational age less than 12 weeks with early pregnancy loss from March 2020 to February 2021 at the Department of Obstetrics and Gynecology, Queen Savang Vadhana Memorial Hospital, were included. For group 1 (n=54), 600 mcg misoprostol was administrated sublingually. For group 2 (n=54), 800 mcg misoprostol was administrated sublingually. If the abortion did not occur, the repeated misoprostol in the same dose would be administrated sublingually every 6 hours for a maximum of three doses. Results: There was no significant difference in the complete abortion rate between the two groups (55.6% in the 600 mcg misoprostol group, 64.7% in the 800 mcg misoprostol group, p=0.339, and 95% CI 0.082 to 1.862). The induction-to-abortion time was 9.5 hours (IQR 6.75 to 48.00) in the 600 mcg misoprostol group and 10 hours (IQR 6.00 to 60.00) in the 800 mcg misoprostol group. The side effects of both groups were similar, included abdominal pain, diarrhea, nausea and vomiting, fever, heavy bleeding, and headache. Conclusion: The efficacy of the 600 mcg misoprostol was noninferior to 800 mcg misoprostol. The adverse effects were similar in both groups. Mean induction-to-abortion time was also similar in both groups. Keywords: Early pregnancy loss; Misoprostol; Medical abortion

June July

Data on leaf plastochron, flower growth and bud abortion in greenhouse-grown A. andreanum were collected from a commercial nursery throughout the year, and additional data were obtained from growers. The leaf plastochron duration was fairly constant from Mar. until Sep. at an average of 72 days. Around 10 Oct. the duration was more than doubled. It then decreased linearly to 72 days again, resulting in high leaf production around Apr. Leaf plastochron seemed to be related to radiation but daylength was probably not involved, as leaf emergence continued during winter. The longest period between flower emergence and flower harvest was around 21 Dec. and the shortest in June-July. Flower production fluctuated strongly, with a minimum in Mar. and a maximum in the second half of June. This maximum was related to the high leaf production in Feb.-Mar. The low production in Mar. was the result of a high abortion rate (near 100%) of flower buds in Dec. The year-round average abortion rate was about 50%.
