Abstract
We assessed the discontinuation rate and the reason for discontinuation of common contraceptives used by reproductive-aged Thai women. We recruited 1880 women aged 18–45 years from the ...Family Planning Clinic of the Chulalongkorn Hospital in Bangkok. The participants were followed at three, six and twelve months. A Cox proportional hazards model was used to determine personal risks of discontinuing contraceptives. The incidence rate for discontinuation of combined oral contraceptive pills (COCs), depot medroxyprogesterone acetate (DMPA), copper intrauterine device (IUD), and contraceptive implant(s) were 21.3, 9.2, 4.4, and 2.3/100 person-years, respectively. Most of the women who discontinued (185/222) discontinued contraceptives due to side effects. Compared to contraceptive implant users, the adjusted hazard ratios (aHRs) 95% confidence intervals (CIs) of discontinuing COCs, DMPA, and the copper IUD were 9.6 (4.3–21.8), 4.2 (1.8–10.0), and 2.2 (0.8–5.9), respectively. Lower income, higher parity, history of miscarriage, and history of abortion were independent predictors of contraceptive discontinuation in a multivariable model.
Menopause, which may accelerate the hallmarks of the natural aging process, represents a point in time characterized by the permanent cessation of menstruation following the loss of ovarian estrogen ...production. Unlike natural menopause, which is characterized by a gradual decrease in estrogen production, when both ovaries are removed before the natural age of menopause, the onset of estrogen deprivation is abrupt. Further, a decrease in genome methylation frequently occurs in aging cells, and the major interspersed repetitive DNA elements in humans are Alu elements. In blood cells, Alu demethylation starts at an age of approximately 40 years, and increases with age. Here, we explored the Alu methylation levels corresponding to age-matched pre-menopausal, naturally postmenopausal, and surgically postmenopausal women aged 45–55 years (n = 60 in each group). Our results indicated that the body mass index (BMI), time-since-menopause, and Alu methylation levels corresponding to the three groups were significantly different. However, no correlations between Alu methylation level and BMI, time-since-menopause, or age were observed. Additionally, the Alu methylation level corresponding to the natural post-menopause group was significantly lower those corresponding to the pre-menopausal (p = 0.001) and surgical post-menopausal (p = 0.037) groups. In conclusion, Alu hypomethylation occurs in naturally postmenopausal women, implying that when women reach the age of natural menopause, the cell aging process may progress significantly with genome hypomethylation. These findings, notwithstanding, further studies are necessary to clarify whether bilateral oophorectomy before the age of menopause affects the cell aging process to a greater extent than natural menopause, and whether estrogen therapy or other interventions can delay cell aging in this regard.
Postmenopausal status is a risk factor for distal sensory polyneuropathy-the most common type of peripheral neuropathy. We aimed to investigate associations between reproductive factors and history ...of exogenous hormone use with distal sensory polyneuropathy among postmenopausal women in the United States using data from the National Health and Nutrition Examination Survey 1999-2004, and to explore the modifying effects of ethnicity on these associations. We conducted a cross-sectional study among postmenopausal women aged ≥ 40 years. Women with a history of diabetes, stroke, cancer, cardiovascular disease, thyroid disease, liver disease, weak or failing kidneys, or amputation were excluded. Distal sensory polyneuropathy was measured using a 10-g monofilament test, and a questionnaire was used to collect data on reproductive history. Multivariable survey logistic regression was used to test the association between reproductive history variables and distal sensory polyneuropathy. In total, 1144 postmenopausal women aged ≥ 40 years were included. The adjusted odds ratios were 8.13 95% confidence interval (CI) 1.24-53.28 and 3.18 (95% CI 1.32-7.68) for age at menarche < 11 years and time since menopause > 20 years, respectively, which were positively associated with distal sensory polyneuropathy; adjusted odds ratios were 0.45 for the history of breastfeeding (95% CI 0.21-0.99) and 0.41 for exogenous hormone use (95% CI 0.19-0.87) were negatively associated. Subgroup analysis revealed ethnicity-based heterogeneity in these associations. Age at menarche, time since menopause, breastfeeding, and exogenous hormone use were associated with distal sensory polyneuropathy. Ethnicity significantly modified these associations.
Abstract We compared the efficacy of 4 mg drospirenone (DRSP) progestin-only pills (POPs) versus combined oral contraceptive pills (COCs) containing 0.02 mg of ethinyl estradiol (EE) and 0.075 mg of ...gestodene (GS) in ovulation inhibition and inducing unfavorable cervical mucus changes using a delayed-starting approach. This randomized controlled trial involved 36 participants aged 18–45 years. The major outcomes included ovulation inhibition assessed using the Hoogland and Skouby score, and cervical mucus permeability, assessed using the modified World Health Organization score. The results demonstrated ovulation inhibition rates of 77.8% for the EE/GS group and 88.9% for the DRSP group. The risk ratio and absolute risk reduction were 0.50 (95% confidence interval CI: 0.10, 2.40) and − 0.11 (95% CI: − 0.35, 0.13), respectively, satisfying the 20% non-inferiority margin threshold. The median time to achieve unfavorable cervical mucus changes was comparable between the DRSP (3 days, interquartile range IQR: 6 days) and EE/GS (3.5 days, IQR: 4 days) groups. However, the DRSP group had a higher incidence of unscheduled vaginal bleeding (55.56% vs. 11.11%; p = 0.005). DRSP-only pills, initiated on days 7–9 of the menstrual cycle, were non-inferior to EE/GS pills in ovulation inhibition. However, they exhibited delayed unfavorable cervical mucus changes compared to the standard two-day backup recommendation.

Summary Background Cervical intraepithelial neoplasia grade 2 or greater (CIN2+) is the surrogate endpoint used in licensure trials of human papillomavirus (HPV) vaccines. Vaccine efficacy against ...CIN3+, the immediate precursor to invasive cervical cancer, is more difficult to measure because of its lower incidence, but provides the most stringent evidence of potential cancer prevention. We report vaccine efficacy against CIN3+ and adenocarcinoma in situ (AIS) in the end-of-study analysis of PATRICIA (PApilloma TRIal against Cancer In young Adults). Methods Healthy women aged 15–25 years with no more than six lifetime sexual partners were included in PATRICIA, irrespective of their baseline HPV DNA status, HPV-16 or HPV-18 serostatus, or cytology. Women were randomly assigned (1:1) to receive an HPV-16/18 AS04-adjuvanted vaccine or a control hepatitis A vaccine via an internet-based central randomisation system using a minimisation algorithm to account for age ranges and study sites. The patients and study investigators were masked to allocated vaccine. The primary endpoint of PATRICIA has been reported previously. In the present end-of-study analysis, we focus on CIN3+ and AIS in the populations of most clinical interest, the total vaccinated cohort (TVC) and the TVC-naive. The TVC comprised all women who received at least one vaccine dose, approximating catch-up populations and including sexually active women (vaccine n=9319; control=9325). The TVC-naive comprised women with no evidence of oncogenic HPV infection at baseline, approximating early adolescent HPV exposure (vaccine n=5824; control=5820). This study is registered with ClinicalTrials.gov , number NCT00122681. Findings Vaccine efficacy against CIN3+ associated with HPV-16/18 was 100% (95% CI 85·5–100) in the TVC-naive and 45·7% (22·9–62·2) in the TVC. Vaccine efficacy against all CIN3+ (irrespective of HPV type in the lesion and including lesions with no HPV DNA detected) was 93·2% (78·9–98·7) in the TVC-naive and 45·6% (28·8–58·7) in the TVC. In the TVC-naive, vaccine efficacy against all CIN3+ was higher than 90% in all age groups. In the TVC, vaccine efficacy against all CIN3+ and CIN3+ associated with HPV-16/18 was highest in the 15–17 year age group and progressively decreased in the 18–20 year and 21–25 year age groups. Vaccine efficacy against all AIS was 100% (31·0–100) and 76·9% (16·0–95·8) in the TVC-naive and TVC, respectively. Serious adverse events occurred in 835 (9·0%) and 829 (8·9%) women in the vaccine and control groups, respectively; only ten events (0·1%) and five events (0·1%), respectively, were considered to be related to vaccination. Interpretation PATRICIA end-of-study results show excellent vaccine efficacy against CIN3+ and AIS irrespective of HPV DNA in the lesion. Population-based vaccination that incorporates the HPV-16/18 vaccine and high coverage of early adolescents might have the potential to substantially reduce the incidence of cervical cancer.

Summary Background We evaluated the efficacy of the human papillomavirus HPV-16/18 AS04-adjuvanted vaccine against non-vaccine oncogenic HPV types in the end-of-study analysis after 4 years of ...follow-up in PATRICIA (PApilloma TRIal against Cancer In young Adults). Methods Healthy women aged 15–25 years with no more than six lifetime sexual partners were included in PATRICIA irrespective of their baseline HPV DNA status, HPV-16 or HPV-18 serostatus, or cytology. Women were randomly assigned (1:1) to HPV-16/18 vaccine or a control hepatitis A vaccine, via an internet-based central randomisation system using a minimisation algorithm to account for age ranges and study sites. The study was double-blind. The primary endpoint of PATRICIA has been reported previously; the present analysis evaluates cross-protective vaccine efficacy against non-vaccine oncogenic HPV types in the end-of-study analysis. Analyses were done for three cohorts: the according-to-protocol cohort for efficacy (ATP-E; vaccine n=8067, control n=8047), total vaccinated HPV-naive cohort (TVC-naive; no evidence of infection with 14 oncogenic HPV types at baseline, approximating young adolescents before sexual debut; vaccine n=5824, control n=5820), and the total vaccinated cohort (TVC; all women who received at least one vaccine dose, approximating catch-up populations that include sexually active women; vaccine n=9319, control=9325). Vaccine efficacy was evaluated against 6-month persistent infection, cervical intraepithelial neoplasia grade 2 or greater (CIN2+) associated with 12 non-vaccine HPV types (individually or as composite endpoints), and CIN3+ associated with the composite of 12 non-vaccine HPV types. This study is registered with ClinicalTrials.gov , number NCT00122681. Findings Consistent vaccine efficacy against persistent infection and CIN2+ (with or without HPV-16/18 co-infection) was seen across cohorts for HPV-33, HPV-31, HPV-45, and HPV-51. In the most conservative analysis of vaccine efficacy against CIN2+, where all cases co-infected with HPV-16/18 were removed, vaccine efficacy was noted for HPV-33 in all cohorts, and for HPV-31 in the ATP-E and TVC-naive. Vaccine efficacy against CIN2+ associated with the composite of 12 non-vaccine HPV types (31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68), with or without HPV-16/18 co-infection, was 46·8% (95% CI 30·7–59·4) in the ATP-E, 56·2% (37·2–69·9) in the TVC-naive, and 34·2% (20·4–45·8) in the TVC. Corresponding values for CIN3+ were 73·8% (48·3–87·9), 91·4% (65·0–99·0), and 47·5% (22·8–64·8). Interpretation Data from the end-of-study analysis of PATRICIA show cross-protective efficacy of the HPV-16/18 vaccine against four oncogenic non-vaccine HPV types—HPV-33, HPV-31, HPV-45, and HPV-51—in different trial cohorts representing diverse groups of women.

Abstract Background Unintended pregnancies can adversely affect maternal health, preventable through timely postpartum contraception. During the COVID-19 pandemic, family planning services were ...constrained by policies that curtailed outpatient visits. We investigated the prevalence of postpartum contraceptive initiation at King Chulalongkorn Memorial Hospital (KCMH) during January to June 2020, comparing with the same period in 2019, and identified factors associated with such initiation. Methods We reviewed the medical records of 4506 postpartum women who delivered at KCMH during the study period. Logistic regression was conducted to test the association between early COVID-19 phase deliveries and post-partum long acting reversible contraception (LARC) initiation including copper intrauterine devices, levonorgestrel intrauterine systems, contraceptive implants, and progestogen-only injectable contraceptives. Results A total of 3765 women (83.6%), of whom 1821 delivered during the pandemic and 1944 during the historical cohort period, were included in this study. The proportion of women who initiated non-permanent modern contraceptives at six weeks postpartum was comparable between the COVID-19 (73.4%) and historical cohort (75.3%) ( p = 0.27) periods. The proportion of women who initiated LARC at six weeks postpartumwas comparable between the historical cohort period (22.5%) and the COVID-19 (19.7%) ( p = 0.05) period. Accessing a six-week postpartum check-up was independently associated with LARC initiation, of which the adjusted odds ratio (OR) (95% confidence interval) was 3.01 (2.26 to 4.02). Conclusions Our findings demonstrated that accessing postpartum care significantly associate with the use of LARC. The data suggest the strong influence of postpartum check-ups in facilitating the adoption of effective contraception, emphasizing the need for accessible postpartum care to sustain maternal health during health crises.
The recently amended Thai abortion law allows pregnant women to undergo abortions up to the gestational age of 12 weeks. Medical abortion is significant because it has revolutionized access to safe ...abortion care-abortion medicine can now be safely and effectively administered outside of a healthcare facility to women in early pregnancy. This contribution supports the pharmacists' role in interprofessional safe abortion teamwork. Adequate knowledge of the current laws regarding safe abortion services will increase pharmacists' competence in providing services. However, safe abortions as a subject have not been formally incorporated into the curriculum for Thai pharmacy students. Therefore, this study aimed to evaluate the knowledge, attitude, and intended practice of fifth-year pharmacy students at Chulalongkorn University.
A cross-sectional study was conducted using an electronic self-administered questionnaire adapted from previously published studies to evaluate participants' knowledge of the recently amended Thai abortion law, attitude toward abortion, and intended practices. The invitations were sent to all fifth-year pharmacy students at Chulalongkorn University.
Among all invitations sent, 104/150 (69.3%) participants responded to the survey. Only a third of the participants (31.7%) had good knowledge scores. Based on five questions regarding the gestational age limit for legal abortion, most participants (52.7%) answered questions incorrectly. Although more than half of the participants (52.5%) disagreed with two pro-choice statements, an overwhelming majority (87.5%) agreed that abortion was a woman's right. Safe abortion services were mostly agreed upon with serious fetal defects (91.9%), non-HIV maternal health conditions (82.2%), and sexual assaults (77.4%). A positive attitude toward abortion affects the intention to perform an abortion under socioeconomic conditions.
Most participants lacked knowledge on the amended abortion law, especially on the gestational limits of abortion. Participants with favorable attitudes toward abortion tended to be more liberal regarding safe abortion services.
Postpartum sterilization in Thailand has relatively few barriers compared to other countries. The procedure is covered by some healthcare plans, and paid out-of-pocket for others. We aim to determine ...if healthcare coverage and other socioeconomic factors affect the rate of postpartum sterilization in an urban, tertiary hospital.
We conducted a secondary analysis of data from a retrospective cohort of 4482 postpartum women who delivered at our hospital. Multivariable logistic regression was conducted to determine if sterilization reimbursement affects immediate postpartum sterilization rate.
Overall immediate postpartum sterilization rate was 17.8%. Route of delivery and parity were similar in those who were reimbursed and those who were not. Women aged over 25 were more likely to have a healthcare plan that does not cover postpartum sterilization. Women whose healthcare plan reimbursed the procedure trended towards postpartum sterilization when compared to women who were not (aOR 1.05, 95% CI 0.86-1.28, p-value = 0.632). Women who delivered via cesarean section were more likely to undergo sterilization at the time of delivery (aOR = 5.87; 95% CI 4.77-7.24, p-value = < 0.001). Women aged 40-44 years were 2.70 times as likely to choose sterilization than those aged 20-24 years (aOR = 2.70; 95% CI 1.61-4.53, p-value < 0.001).
Healthcare coverage of the procedure was not associated with increased postpartum sterilization in our setting.
Introduction. Termination of pregnancy in a patient with huge uterine leiomyomata poses significant challenges to clinicians. In this study, we report the successful termination of pregnancy in a ...patient with large multiple uterine leiomyomata using a combined regimen of drugs for medical abortion. Case. A 42-year-old woman, 6 weeks pregnant, presented to the Family Planning Clinic with an unintended pregnancy. She had a large, irregular abdominal midline mass, equivalent in size to 30-32 weeks of pregnancy. Abdominal and transvaginal ultrasound examinations revealed a small intrauterine gestational sac with a yolk sac and multiple large uterine leiomyomata. Treatment with mifepristone (200 mg) was initiated at the clinic. In addition, she was instructed to sublingually take 800 μg of misoprostol after 24–48 h. Two weeks later, at the follow-up visit, the patient complained of continued light bleeding. A pelvic examination showed that her cervix was dilated by 1 cm. In addition, abdominal and transvaginal ultrasound revealed a thick, inhomogeneous endometrium. Owing to light bleeding and no anemia or infection, the patient received two additional doses of 800 μg misoprostol vaginally. Her bleeding subsided for 61 days, and she resumed her normal menstrual cycle. Conclusion. A first-trimester pregnancy with large multiple uterine leiomyomata can be safely terminated using a combination regimen of drugs for medical abortion. However, an additional dose of misoprostol is required for the successful termination of pregnancy.
