Society of Family Planning Clinical Recommendation: Medication management for early pregnancy loss.

Early pregnancy loss (EPL), also known as miscarriage or spontaneous abortion, makes up 15-20% of all clinically recognized pregnancies. EPL is a broad term that includes intrauterine pregnancies (IUPs) with findings that suggest the pregnancy may not progress or definitely will not progress; pregnancies with a gestational sac (GS) in the lower endometrial cavity or endocervical canal in the process of expulsion; residual pregnancy tissue or persistent GS; and complete passage of the GS without residual tissue. This document addresses medication management of EPL in which the complete passage of the GS has not yet occurred, including pregnancies concerning for and diagnostic of EPL (sometimes called "missed abortion") and EPL in progress.

Pregnancy Outcomes among Pregnant Persons after COVID-19 Vaccination: Assessing Vaccine Safety in Retrospective Cohort Analysis of U.S. National COVID Cohort Collaborative (N3C).

COVID-19 vaccines have been shown to be effective in preventing severe illness, including among pregnant persons. The vaccines appear to be safe in pregnancy, supporting a continuously favorable overall risk/benefit profile, though supportive data for the U.S.

Effect of Integrase Strand Transfer Inhibitor Use on Time to HIV Viral Suppression before Delivery.

Objectives: We sought to determine whether pregnant individuals with human immunodeficiency virus (HIV) prescribed integrase strand transfer inhibitor (INSTI) antiretrovirals (ARVs) achieve viral suppression faster than individuals taking non-INSTI regimens and to determine whether there were differences in viral suppression at delivery among INSTI ARVs.

Methods: This is a retrospective cohort study of pregnant individuals with HIV who delivered a live infant during the study period (January 1, 2009-December 31, 2020). Patients' ARV therapy (ART) was classified as including INSTI or non-INSTI.

Who is pregnant? Defining real-world data-based pregnancy episodes in the National COVID Cohort Collaborative (N3C).

Objectives: To define pregnancy episodes and estimate gestational age within electronic health record (EHR) data from the National COVID Cohort Collaborative (N3C).

Materials And Methods: We developed a comprehensive approach, named Hierarchy and rule-based pregnancy episode Inference integrated with Pregnancy Progression Signatures (HIPPS), and applied it to EHR data in the N3C (January 1, 2018-April 7, 2022). HIPPS combines: (1) an extension of a previously published pregnancy episode algorithm, (2) a novel algorithm to detect gestational age-specific signatures of a progressing pregnancy for further episode support, and (3) pregnancy start date inference.

Attitudes on breast feeding among persons with HIV who have given birth and their perceptions of coercion during counseling on safe infant feeding practices.

Persons with HIV can receive mixed messages about the safety of breastfeeding. We sought to assess if they felt coerced to formula feed when counseled about practices to reduce HIV transmission. Persons with HIV who had given birth were eligible to complete a survey to describe their experiences with infant feeding counseling and if they felt coerced to formula feed.

Perception of coercion during contraceptive counseling among individuals with HIV.

Objective: Historically, individuals with HIV have reported feeling coerced during contraceptive counseling or experienced forced sterilization. The purpose of this study was to assess perceptions of coercion related to counseling and influence on postpartum contraceptive choice among individuals with HIV.

Methods: This is a mixed methods study conducted in Georgia, North Carolina, Pennsylvania, and South Carolina between March 2020 and June 2021.

Who is pregnant? defining real-world data-based pregnancy episodes in the National COVID Cohort Collaborative (N3C).

Objective: To define pregnancy episodes and estimate gestational aging within electronic health record (EHR) data from the National COVID Cohort Collaborative (N3C).

Materials And Methods: We developed a comprehensive approach, named H ierarchy and rule-based pregnancy episode I nference integrated with P regnancy P rogression S ignatures (HIPPS) and applied it to EHR data in the N3C from 1 January 2018 to 7 April 2022. HIPPS combines: 1) an extension of a previously published pregnancy episode algorithm, 2) a novel algorithm to detect gestational aging-specific signatures of a progressing pregnancy for further episode support, and 3) pregnancy start date inference.

Society of Family Planning Clinical Recommendations: Contraceptive Care in the Context of Pandemic Response.

The coronavirus disease 2019 (COVID-19) pandemic has posed a burden to healthcare systems around the world and has changed the way people access health services, including contraception. This document sets forth guidance from the Society of Family Planning for providing contraceptive care in the context of the COVID-19 pandemic, including when access to healthcare is restricted due to pandemic response. It also outlines the role of telehealth for providing contraceptive care beyond the pandemic.

Impact of Integrase Strand Transfer Inhibitor Use During Pregnancy on Viral Suppression at Delivery and Infant Outcomes: A Statewide Retrospective Cohort Study.

Background: We sought to determine whether pregnant women with HIV prescribed integrase strand transfer inhibitor (INSTI) were more likely to have viral suppression at delivery and any increased risk of adverse infant outcomes.

Methods: This was a retrospective, statewide cohort study of women with HIV and their HIV-exposed infants who delivered in South Carolina from 2008 to 2019. Women's antenatal AVRs were classified as INSTI or non-INSTI.

Quality improvement to evaluate and provide treatment for chronic hepatitis C postpartum.

Background: Chronic hepatitis C virus (HCV) infections are increasing among reproductive age individuals. Direct acting antivirals (DAAs) can cure HCV, but the use of DAAs is not currently recommended during pregnancy and breastfeeding. Individuals with HCV commonly have inadequate prenatal and postnatal care.

Pharmacokinetic and Pharmacodynamic Impacts of Depot Medroxyprogesterone Acetate Use on HIV Pre-exposure Prophylaxis in Women.

Background: Depot medroxyprogesterone acetate (DMPA) is a commonly used contraceptive in areas where use of tenofovir disoproxil fumarate and emtricitabine for HIV pre-exposure prophylaxis (PrEP) is increasing.

Objectives: We aimed to investigate the impact of DMPA on PrEP drug pharmacokinetics and pharmacodynamics in women using PrEP before and after DMPA administration.

Methods: In this pilot study, 12 HIV-negative women ages 18-45 underwent biological sample collection at 3 time points: before study drug, after 2 weeks of daily PrEP use alone, and after 2 weeks of daily PrEP and concomitant DMPA use.

Diagnosis, Treatment, Follow-up, and Persistence of Trichomonas vaginalis in Women 45 Years and Older According to HIV Status: A 10-Year Retrospective Cohort.

Background: Trichomonas vaginalis is a common treatable sexually transmitted infection among older women. Persistent T. vaginalis infection after treatment is common among women with human immunodeficiency virus (HIV).

Development of a genomic DNA reference material panel for Rett syndrome (MECP2-related disorders) genetic testing.

Rett syndrome is a dominant X-linked disorder caused by point mutations (approximately 80%) or by deletions or insertions (approximately 15% to 18%) in the MECP2 gene. It is most common in females but lethal in males, with a distinctly different phenotype. Rett syndrome patients have severe neurological and behavioral problems.

Truncating CLCN1 mutations in myotonia congenita: variable patterns of inheritance.

Introduction: Myotonia congenita due to protein truncating CLCN1 mutations is associated with variable patterns of inheritance.

Methods: Three family kindreds are described, all of whom possess protein truncating mutations (Y33X, fs503X, R894X). One lineage also has coexistent R894X, A313T, and A320V mutations.

Development of a genomic DNA reference material panel for myotonic dystrophy type 1 (DM1) genetic testing.

Myotonic dystrophy type 1 (DM1) is caused by expansion of a CTG triplet repeat in the 3' untranslated region of the DMPK gene that encodes a serine-threonine kinase. Patients with larger repeats tend to have a more severe phenotype. Clinical laboratories require reference and quality control materials for DM1 diagnostic and carrier genetic testing.

Developmental trajectories in syndromes with intellectual disability, with a focus on Wolf-Hirschhorn and its cognitive-behavioral profile.

Few studies exist of developmental trajectories in children with intellectual disability, and none for those with subtelomeric deletions. We compared developmental trajectories of children with Wolf-Hirschhorn syndrome to other genetic disorders. We recruited 106 children diagnosed with fragile X, Williams-Beuren syndrome, or Wolf-Hirschhorn syndrome, assessing their intellectual and adaptive behavior abilities.

Quality assurance for Duchenne and Becker muscular dystrophy genetic testing: development of a genomic DNA reference material panel.

Duchenne and Becker muscular dystrophies (DMD/BMD) are allelic X-linked recessive disorders that affect approximately 1 in 3500 and 1 in 20,000 male individuals, respectively. Approximately 65% of patients with DMD have deletions, 7% to 10% have duplications, and 25% to 30% have point mutations in one or more of the 79 exons of the dystrophin gene. Most clinical genetics laboratories test for deletions, and some use technologies that can detect smaller mutations and duplications.

The course of cognitive-behavioral development in children with the FMR1 mutation, Williams-Beuren syndrome, and neurofibromatosis type 1: The effect of gender.

The course of cognitive-behavioral development in children with intellectual disabilities produced by genetic disorders has only recently begun to be examined systematically. Unfortunately, these studies are few in number. Previously, we examined cognitive-behavioral development in children with the fragile X (FMR1) mutation and found longitudinal decreases in both IQ and adaptive behavior (DQ) scores in most males and females with the full mutation.

Development of genomic reference materials for cystic fibrosis genetic testing.

The number of different laboratories that perform genetic testing for cystic fibrosis is increasing. However, there are a limited number of quality control and other reference materials available, none of which cover all of the alleles included in commercially available reagents or platforms. The alleles in many publicly available cell lines that could serve as reference materials have neither been confirmed nor characterized.

Recessive CLCN1 mutation presenting as Thomsen disease.

This case report describes a young man referred for electrodiagnostic evaluation for hand stiffness and intermittent numbness. His needle electromyography revealed diffusely increased insertional and spontaneous motor activity in the form of myotonic discharges. Given the finding of symptomatic myotonia also in his mother, Thomsen myotonia was suspected.

Extraocular muscle hypertrophy in myotonia congenita.

Myotonia congenita (MC) is a rare disorder of skeletal muscle caused by mutations in the CLCN1 gene,(1,2) which encodes the chloride ion channel found in the t-tubule of skeletal muscle. MC is characterized by impaired relaxation of voluntary muscle after sudden contraction that diminishes with muscle activity, known as the "warm-up effect." Individuals with MC can develop muscular hypertrophy despite little physical activity.

Studies of age-correlated features of cognitive-behavioral development in children and adolescents with genetic disorders.

Studies of age-related features of cognitive-behavioral deficits produced by genetic mutations permit us to draw inferences about how brain development may be related cognitive ability as the child ages. Except for Down syndrome (DS) and the fragile X mutation (FRAXA), little is known about the longitudinal changes in cognitive-behavioral development in individuals with genetic abnormalities producing learning disabilities (LD) or mental retardation (MR). The purpose of this prospective study was to compare and contrast age related to cognitive abilities, adaptive and maladaptive behaviors in children and adolescents in the same age range, diagnosed with one of three genetic disorders: the FRAXA mutation, Neurofibromatosis type 1 (NF1) or Williams-Beuren syndrome (WBS).

Cognitive effects of diarrhea, malnutrition, and Entamoeba histolytica infection on school age children in Dhaka, Bangladesh.

Cognitive function was assessed in 191 Bangladeshi children 6-9 years of age using verbal and nonverbal tests. These scores were added to a health surveillance database that was compiled over the four previous years that includes incidence of diarrhea and Entamoeba histolytica infection and nutritional status. The associations of diarrhea, malnutrition, and social factors with cognitive scores were analyzed statistically, and associations between diarrhea and test scores were controlled for the influence of social factors.
