RESUMO

OBJECTIVE: We describe changes in commercial insurance claims for contraceptive services during the beginning of the COVID-19 pandemic. METHODS: We analyzed commercial insurance claims using IQVIA PharMetrics Plus data from more than 9 million U.S. females aged 15-49 years, enrolled during any month, January 2019 through September 2020. We calculated monthly rates of outpatient claims for intrauterine devices (IUDs), implants, and injectable contraception and monthly rates of pharmacy claims for contraceptive pills, patches, and rings. We used Joinpoint regression analysis to identify when statistically significant changes occurred in trends of monthly claims rates for each contraceptive method. We calculated monthly percentages of claims for contraceptive counseling via telehealth. RESULTS: Monthly claims rates decreased for IUDs (-50%) and implants (-43%) comparing February 2020 with April 2020 but rebounded by June 2020. Monthly claims rates for injectables decreased (-19%) comparing January 2019 with September 2020, and monthly claims rates for pills, patches, and rings decreased (-22%) comparing July 2019 with September 2020. The percentage of claims for contraceptive counseling occurring via telehealth was low (<1%) in 2019, increased to 34% in April 2020, and decreased to 9-12% in June-September 2020. CONCLUSIONS: Substantial changes in commercial insurance claims for contraceptive services occurred during the beginning of the COVID-19 pandemic, including transient decreases in IUD and implant claims and increases in telehealth contraceptive counseling claims. Contraceptive claims data can be used by decision makers to identify service gaps and evaluate use of interventions like telehealth to improve contraceptive access, including during public health emergencies.

RESUMO

Objectives. To describe breastfeeding initiation and breastfeeding at 1, 2, and 3 months, and information sources on breastfeeding among women with a recent live birth by disability status. Methods. We analyzed October 2018 to December 2020 data from the Pregnancy Risk Assessment Monitoring System for 24 sites in the United States that included the Washington Group Short Set of Questions on Disability (seeing, hearing, walking or climbing stairs, remembering or concentrating, self-care, communicating). We defined disability as reporting "a lot of difficulty" or "cannot do this at all" on any of these questions. Results. Among 39 673 respondents, 6.0% reported disability. In adjusted analyses, breastfeeding was lower among respondents with disability at 2 (62.6% vs 66.6%; adjusted prevalence ratio [APR] = 0.94; 95% confidence interval [CI] = 0.89, 0.99) and 3 months (54.7% vs 59.6%; APR = 0.92; 95% CI = 0.86, 0.98) than those without disability. Respondents with disability were less likely to receive information from health care providers or support professionals (89.3% vs 92.3%), but as likely from breastfeeding or lactation specialists (78.1% vs 75.3%). Conclusions. Strategies to ensure women with disability, receive breastfeeding support, including breastfeeding information, could improve breastfeeding outcomes.

RESUMO

Problem/Condition: CDC conducts abortion surveillance to document the number and characteristics of women obtaining legal induced abortions and number of abortion-related deaths in the United States. Period Covered: 2021. Description of System: Each year, CDC requests abortion data from the central health agencies for the 50 states, the District of Columbia, and New York City. For 2021, a total of 48 reporting areas voluntarily provided aggregate abortion data to CDC. Of these, 47 reporting areas provided data each year during 2012-2021. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births), respectively. Abortion-related deaths from 2020 were assessed as part of CDC's Pregnancy Mortality Surveillance System (PMSS). Results: A total of 625,978 abortions for 2021 were reported to CDC from 48 reporting areas. Among 47 reporting areas with data each year during 2012-2021, in 2021, a total of 622,108 abortions were reported, the abortion rate was 11.6 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 204 abortions per 1,000 live births. From 2020 to 2021, the total number of abortions increased 5% (from 592,939 total abortions), the abortion rate increased 5% (from 11.1 abortions per 1,000 women aged 15-44 years), and the abortion ratio increased 4% (from 197 abortions per 1,000 live births). From 2012 to 2021, the total number of reported abortions decreased 8% (from 673,634), the abortion rate decreased 11% (from 13.1 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 1% (from 207 abortions per 1,000 live births).In 2021, women in their 20s accounted for more than half of abortions (57.0%). Women aged 20-24 and 25-29 years accounted for the highest percentages of abortions (28.3% and 28.7%, respectively) and had the highest abortion rates (19.7 and 19.4 abortions per 1,000 women aged 20-24 and 25-29 years, respectively). By contrast, adolescents aged <15 years and women aged ≥40 years accounted for the lowest percentages of abortions (0.2% and 3.6%, respectively) and had the lowest abortion rates (0.4 and 2.5 abortions per 1,000 women aged <15 and ≥40 years, respectively). However, abortion ratios were highest among adolescents (aged ≤19 years) and lowest among women aged 30-39 years.From 2020 to 2021, abortion rates increased among women aged 20-39 years, decreased among adolescents aged 15-19 years, and did not change among adolescents aged <15 years and women aged ≥40 years. Abortion rates decreased from 2012 to 2021 among all age groups, except women aged 30-34 years for whom it increased. The decrease in the abortion rate from 2012 to 2021 was highest among adolescents compared with any other age group. From 2020 to 2021, abortion ratios increased for women aged 15-24 years, decreased among adolescents aged <15 years and women aged ≥35 years and did not change for women aged 25-34 years. From 2012 to 2021, abortion ratios increased among women aged 15-29 years and decreased among adolescents aged <15 years and women aged ≥30 years. The decrease in abortion ratio from 2012 to 2021 was highest among women aged ≥40 years compared with any other age group.In 2021, the majority (80.8%) of abortions were performed at ≤9 weeks' gestation, and nearly all (93.5%) were performed at ≤13 weeks' gestation. During 2012-2021, the percentage of abortions performed at >13 weeks' gestation remained ≤8.7%. In 2021, the highest percentage of abortions were performed by early medication abortion at ≤9 weeks' gestation (53.0%), followed by surgical abortion at ≤13 weeks' gestation (37.6%), surgical abortion at >13 weeks' gestation (6.4%), and medication abortion at >9 weeks' gestation (3.0%); all other methods were uncommon (<0.1%). Among those that were eligible (≤9 weeks' gestation), 66.6% of abortions were early medication abortions. In 2020, the most recent year for which PMSS data were reviewed for pregnancy-related deaths; six women died as a result of complications from legal induced abortion. Interpretation: Among the 47 areas that reported data continuously during 2012-2021, overall decreases were observed during 2012-2021 in the total number, rate, and ratio of reported abortions; however, from 2020 to 2021, increases were observed across all measures. Public Health Action: Abortion surveillance can be used to help evaluate programs aimed at promoting equitable access to patient-centered quality contraceptive services in the United States to reduce unintended pregnancies.

Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births), respectively. Abortion-related deaths from 2019 were assessed as part of CDC's Pregnancy Mortality Surveillance System (PMSS). Results: A total of 620,327 abortions for 2020 were reported to CDC from 49 reporting areas. Among 48 reporting areas with data each year during 2011-2020, in 2020, a total of 615,911 abortions were reported, the abortion rate was 11.2 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 198 abortions per 1,000 live births. From 2019 to 2020, the total number of abortions decreased 2% (from 625,346 total abortions), the abortion rate decreased 2% (from 11.4 abortions per 1,000 women aged 15-44 years), and the abortion ratio increased 2% (from 195 abortions per 1,000 live births). From 2011 to 2020, the total number of reported abortions decreased 15% (from 727,554), the abortion rate decreased 18% (from 13.7 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 9% (from 217 abortions per 1,000 live births).In 2020, women in their 20s accounted for more than half of abortions (57.2%). Women aged 20-24 and 25-29 years accounted for the highest percentages of abortions (27.9% and 29.3%, respectively) and had the highest abortion rates (19.2 and 19.0 abortions per 1,000 women aged 20-24 and 25-29 years, respectively). By contrast, adolescents aged <15 years and women aged ≥40 years accounted for the lowest percentages of abortions (0.2% and 3.7%, respectively) and had the lowest abortion rates (0.4 and 2.6 abortions per 1,000 women aged <15 and ≥40 years, respectively). However, abortion ratios were highest among adolescents (aged ≤19 years) and lowest among women aged 25-39 years.Abortion rates decreased from 2011 to 2020 among all age groups. The decrease in abortion rate was highest among adolescents compared with any other age group. From 2019 to 2020, abortion rates decreased or did not change for all age groups. Abortion ratios decreased from 2011 to 2020 for all age groups, except adolescents aged 15-19 years and women aged 25-29 years for whom abortion ratios increased. The decrease in abortion ratio was highest among women aged ≥40 years compared with any other age group. From 2019 to 2020, abortion ratios decreased for adolescents aged <15 years and women aged ≥35 and increased for women 15-34 years.In 2020, 80.9% of abortions were performed at ≤9 weeks' gestation, and nearly all (93.1%) were performed at ≤13 weeks' gestation. During 2011-2020, the percentage of abortions performed at >13 weeks' gestation remained consistently low (≤9.2%). In 2020, the highest percentage of abortions were performed by early medical abortion at ≤9 weeks' gestation (51.0%), followed by surgical abortion at ≤13 weeks' gestation (40.0%), surgical abortion at >13 weeks' gestation (6.7%), and medical abortion at >9 weeks' gestation (2.4%); all other methods were uncommon (<0.1%). Among those that were eligible (≤9 weeks' gestation), 63.9% of abortions were early medical abortions. In 2019, the most recent year for which PMSS data were reviewed for pregnancy-related deaths, four women died as a result of complications from legal induced abortion. Interpretation: Among the 48 areas that reported data continuously during 2011-2020, overall decreases were observed during 2011-2020 in the total number, rate, and ratio of reported abortions. From 2019 to 2020, decreases also were observed in the total number and rate of reported abortions; however, a 2% increase was observed in the total abortion ratio. Public Health Action: Abortion surveillance can be used to help evaluate programs aimed at promoting equitable access to patient-centered quality contraceptive services in the United States to reduce unintended pregnancies.

RESUMO

Equitable access to contraception is critical for reproductive autonomy. Using cross-sectional data from the DocStyles survey administered September-October 2020 (68% response rate), we compared changes in family planning-related clinical services and healthcare delivery strategies before and during the COVID-19 pandemic and assessed service provision issues among 1063 U.S. physicians whose practice provided family planning services just before the pandemic. About one-fifth of those whose practices provided the following services or strategies just before the pandemic discontinued these services during the pandemic: long-acting reversible contraception (LARC) placement (16%); LARC removal (17%); providing or prescribing emergency contraceptive pills (ECPs) in advance (18%); and reminding patients about contraception injections or LARC removal or replacement (20%). Many practices not providing the following services or strategies just before the pandemic initiated these services during the pandemic: telehealth for contraception initiation (43%); telehealth for contraception continuation (48%); and renewing contraception prescriptions without requiring an office visit (36%). While a smaller proportion of physicians reported service provision issues in the month before survey completion than at any point during the pandemic, about one-third still reported fewer adult females seeking care (37%) and technical challenges with telehealth (32%). Discontinuation of key family planning services during the COVID-19 pandemic may limit contraception access and impede reproductive autonomy. Implementing healthcare service delivery strategies that reduce the need for in-person visits (e.g., telehealth for contraception, providing or prescribing ECPs in advance) may decrease disruptions in care. Resources exist for public health and clinical efforts to ensure contraception access during the pandemic.

RESUMO

BACKGROUND: Immediate contraceptive initiation, including start of a method before abortion completion, is a convenient option for women seeking abortion care. OBJECTIVES: To evaluate the effect of systemic hormonal contraception initiation on medical abortion effectiveness and the safety of hormonal contraceptive methods following abortion. DATA SOURCES: PubMed, Popline, Cochrane Library, and Clinicaltrials.gov. STUDY ELIGIBILITY CRITERIA: Studies that assessed medical abortion effectiveness after systemic hormonal contraception initiation and the safety of hormonal contraception initiation after abortion. PARTICIPANTS: Pregnant persons undergoing or who had recently undergone an abortion. INTERVENTIONS: Initiation of systemic hormonal contraception post abortion or on the day of the first pill of the medical abortion. STUDY APPRAISAL AND SYNTHESIS METHODS: We assessed study quality using the US Preventive Services Task Force evidence grading system. We created narrative summaries and calculated pooled relative risks when appropriate. RESULTS: We identified 16 studies for inclusion, 7 randomized controlled trials, and 9 cohorts. Nine studies assessed medical abortion effectiveness with hormonal contraception initiation and generally found no decreased risk of abortion success or increased risk of additional treatment. One fair-quality study reported a small increase in ongoing pregnancy rate with immediate depot medroxyprogesterone (DMPA) compared with delayed DMPA initiation (3.6% vs 0.9%, risk difference 2.7%, 90% confidence interval 0.4-5.6). We identified no bleeding-related safety concerns following hormonal contraception initiation after medical or surgical abortion. Pooled results were too imprecise to draw firm conclusions. LIMITATIONS: Included studies were poor or fair quality and primarily in high-income or upper-middle-income settings. CONCLUSIONS: Abortion effectiveness did not differ between immediate vs delayed initiation of most systemic hormonal contraceptive methods after a first trimester medical abortion. However, immediate DMPA initiation did show increased ongoing pregnancy. Bleeding effects with hormonal contraception initiation postabortion appeared minimal. IMPLICATIONS: Initiating a hormonal contraceptive method after an abortion and as early as the same day as the first pill of the medical abortion is an option if contraception is desired. The slight increase in ongoing pregnancy with immediate DMPA initiation highlights the importance of information provision during contraceptive counseling.

RESUMO

Medical abortion is a safe, effective, and acceptable option for patients seeking an early nonsurgical abortion. In 2014, medical abortion accounted for nearly one third (31%) of all abortions performed in the United States. State-level attempts to restrict reproductive and sexual health have recently included bills that require physicians to inform women that a medical abortion is reversible. In this commentary, we will review the history, current evidence-based regimen, and regulation of medical abortion. We will then examine current proposed and existing abortion reversal legislation. The objective of this commentary is to ensure physicians are armed with rigorous evidence to inform patients, communities, and policy makers about the safety of medical abortion. Furthermore, given the current paucity of evidence for medical abortion reversal, physicians and policy makers can dispel bad science and misinformation and advocate against medical abortion reversal legislation.

RESUMO

Neurodevelopmental reflex testing is commonly used in clinical practice to assess the maturation of the nervous system. Neurodevelopmental reflexes are also referred to as primitive reflexes. They are sensitive and consistent with later outcomes. Abnormal reflexes are described as an absence, persistence, reappearance, or latency of reflexes, which are predictive indices of infants that are at high risk for neurodevelopmental disorders. Animal models of neurodevelopmental disabilities, such as cerebral palsy, often display aberrant developmental reflexes, as would be observed in human infants. The techniques described assess a variety of neurodevelopmental reflexes in neonatal rats. Neurodevelopmental reflex testing offers the investigator a testing method that is not otherwise available in such young animals. The methodology presented here aims to assist investigators in examining developmental milestones in neonatal rats as a method of detecting early-onset brain injury and/or determining the effectiveness of therapeutic interventions. The methodology presented here aims to provide a general guideline for investigators.

RESUMO

OBJECTIVE: To estimate whether postpartum visit attendance was improved in women exposed to a postpartum patient navigation program compared with those who received care immediately before the program's initiation and to assess whether other postpartum health behaviors improved during the intervention period. METHODS: This is a prospective observational study of women enrolled in a patient navigation program compared with women receiving care before the program. Navigating New Motherhood was a postpartum patient navigation program for adult, English-speaking women receiving prenatal care at a Medicaid-based university clinic. In 2015, Navigating New Motherhood introduced a clinic-level change in which a navigator was hired and assumed supportive and logistic responsibilities for enrolled patients between delivery and postpartum visit completion. We compared medical record data from women who enrolled in Navigating New Motherhood with those of women receiving care in the same clinic for 1 year immediately before Navigating New Motherhood. The primary outcome was postpartum visit attendance. Secondary outcomes included World Health Organization (WHO) Tier 1 or 2 contraception uptake and other health services measures. We conducted bivariable and multivariable analyses. RESULTS: Of the 225 women approached for Navigating New Motherhood participation after program initiation, 96.9% (n=218) enrolled; these women were compared with 256 women in the historical cohort. Most women in both groups were racial or ethnic minorities and all had Medicaid insurance. There were no important differences in demographic, clinical, or health service characteristics between groups, although women in Navigating New Motherhood were more likely to transfer into the clinic for prenatal care and to deliver neonates admitted to the neonatal intensive care unit. The primary outcome, return for postpartum care, was more common among women in Navigating New Motherhood (88.1% compared with 70.3%, P<.001), a difference that persisted after adjustment for potential confounding factors (adjusted odds ratio [OR] 3.57, 95% confidence interval [CI] 2.11-6.04). Women in Navigating New Motherhood also were more likely to receive a WHO Tier 1 or 2 contraceptive method (adjusted OR 1.56, 95% CI 1.02-2.38), postpartum depression screening (adjusted OR 2.82, 95% CI 1.79-4.43), and influenza (adjusted OR 2.10, 95% CI 1.38-3.19) and human papillomavirus vaccination (adjusted OR 2.33, 95% CI 1.25-4.33). CONCLUSION: Implementation of a postpartum navigation program was associated with improved retention in routine postpartum care and frequency of contraception uptake, depression screening, and vaccination.

RESUMO

BACKGROUND: The presence of a fetal inflammatory response is linked to cerebral palsy. Unfortunately no preventive therapies are available. In this study, we determined whether dietary supplementation with broccoli sprouts (BrSp), a phase-II enzyme inducer, would be effective in preventing the behavioural and pathologic manifestations in a rodent model of inflammation during late pregnancy. METHODS: Pregnant Long-Evans rats were administered i.p. Injections of saline (100µl) or lipopolysaccharide (LPS, 200µg/kg), every 12h on embryonic day (E) 19 and 20. In the treatment groups, dams were supplemented with 200mg/day of dried BrSp from E14 until postnatal day 21. Pups underwent a series of neurodevelopmental reflex tests from postnatal day 3-21 followed by neuropathological analyses. RESULTS: Pups born from the LPS group were significantly growth restricted (p<0.001) and delayed in hindlimb placing (p<0.05), cliff avoidance (p<0.05), and gait (p<0.001) compared to controls. In the open field behaviour analyses, LPS pups had an increase in grooming behaviour (p<0.05) and a decreased amount of time spent in the center of the box compared to controls. Dietary supplementation with BrSp to offspring exposed to LPS had increased birth weights (p<0.001), were no longer delayed in acquiring hindlimb placing, cliff avoidance, gait, and posture, and groomed less compared to LPS alone pups (p<0.01). Histological analyses revealed that LPS pups had reduced myelin basic protein compared to controls. CONCLUSIONS: Our data suggest that BrSp dietary supplementation during pregnancy may be effective in preventing growth restriction and neurodevelopmental delays.

RESUMO

We developed a novel assay to examine social interactions in Drosophila and, as a first attempt, apply it here at examining the behavior of Drosophila Fragile X Mental Retardation gene (dfmr1) mutants. Fragile X syndrome is the most common cause of single gene intellectual disability (ID) and is frequently associated with autism. Our results suggest that dfmr1 mutants are less active than wild-type flies and interact with each other less often. In addition, mutants for one allele of dfmr1, dfmr1(B55), are more likely to come in close contact with a wild-type fly than another dfmr1(B55) mutant. Our results raise the possibility of defective social expression with preserved receptive abilities. We further suggest that the assay may be applied in a general strategy of examining endophenoypes of complex human neurological disorders in Drosophila, and specifically in order to understand the genetic basis of social interaction defects linked with ID.
