Principles of care for pregnant and parenting people with substance use disorder: the obstetrician gynecologist perspective.

Substance use in pregnant and parenting persons is common, yet still underdiagnosed. Substance use disorder (SUD) is one of the most stigmatized and undertreated chronic medical conditions, and this is exacerbated in the perinatal period. Many providers are not sufficiently trained in screening or treatment for substance use, so gaps in care for this population persist. Punitive policies towards substance use in pregnancy have proliferated, lead to decreased prenatal care, do not improve birth outcomes, and disproportionately impact Black, Indigenous, and other families of color. We discuss the importance of understanding the unique barriers of pregnancy-capable persons and drug overdose as one of the leading causes of maternal death in the United States. We highlight the principles of care from the obstetrician-gynecologist perspective including care for the dyad, person-centered language, and current medical terminology. We then review treatment of the most common substances, discuss SUD during the birthing hospitalization, and highlight the high risk of mortality in the postpartum period.

Developing a Women's Health track within addiction medicine fellowship: reflections and inspirations.

BACKGROUND: Women who use drugs face sexism and intersectional stigma that influence their drug use experiences and treatment needs. There is a need to build the capacity of addiction medicine specialists who can deliver gender-responsive services and advance research and policy in women-focused addiction care. We describe the development of a Women's Health track within an addiction medicine fellowship program and reflect on successes, challenges, and future directions. MAIN BODY: The Women's Health track was developed in collaboration between program leaders in Addiction Medicine and Obstetrics/Gynecology. Implementing the track led to the development of women-focused rotations and continuity clinics, as well as enrichment of women's health didactic education for all fellows. The fellowship track spurred interdepartmental mentorship and collaboration on research and advocacy projects. CONCLUSION: Addiction medicine fellowships can replicate this curriculum model to advance women-focused education, research, and policy. Future curricula should focus on structural sexism in drug use and addiction treatment throughout a woman's life course.

Racial inequity in methadone dose at delivery in pregnant women with opioid use disorder.

BACKGROUND: Medications for opioid use disorder, including methadone, combined with comprehensive wraparound services, are the gold standard for treatment in pregnancy. Higher methadone doses are associated with treatment retention in pregnancy and relapse prevention. Given known inequities where individuals of color tend to be prescribed lower doses of opioids for other conditions, the purpose of this study was to determine whether there is racial inequity in methadone dose at delivery in pregnant women with opioid use disorder. METHODS: Retrospective review of medical charts identified pregnant women (N = 339) treated with methadone for opioid use disorder during pregnancy at one center from 2012 to 2017. Variables extracted from medical records included race, demographic and relevant clinical information (e.g., methadone dose at delivery, height, weight, etc.). Analyses used simple and multiple linear regressions to determine associations between these characteristics and methadone dose at delivery. RESULTS: The mean methadone doses at delivery among women of color and white women were 105.8 mg and 144.9 mg, respectively (p < .0001). After adjusting for maternal age, gestational age at delivery, body mass index, type of opioid used, and parity, race was significantly and independently associated with methadone dose at delivery, with women of color receiving 36.2 mg less than white women (p = .0003). CONCLUSIONS: Pregnant women of color with opioid use disorder received 67% of the dose of methadone at delivery that white women received. Antiracist responses to prevent provider bias in evaluating dose needs are needed to correct this inequity and prevent undertreatment of opioid use disorder among women of color.

Characterization of the Demographics and Psychiatric Co-Morbidites Among Clients of a Human Rights Clinic in Miami-Dade County, Florida, United States.

Miami-Dade County (MDC) represents a major port of entry for people seeking asylum in the United States, and few studies have systematically evaluated the demographic characteristics of this vulnerable population. Moreover, while the burden of post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) are thought to be higher in this population, the prevalence of these psychiatric conditions in our community is unknown. An analysis of demographics and psychiatric co-morbidities of the Human Rights Clinic (HRC) of Miami's 93 clients between 2010 and 2015 was conducted. The HRC cohort had the following characteristics: median age of 30 years, 52% female, 46% male, 2% transgender or intersex, and 88% originating from Latin America and the Caribbean. The prevalence of PTSD was 67% and MDD was 53% in the HRC population. We conclude that the mental health burden in asylum-seekers in MDC is alarmingly high and that healthcare providers should remain keenly attentive to the unique needs of this population.

Antibiotic-mediated gut microbiome perturbation accelerates development of type 1 diabetes in mice.

The early life microbiome plays important roles in host immunological and metabolic development. Because the incidence of type 1 diabetes (T1D) has been increasing substantially in recent decades, we hypothesized that early-life antibiotic use alters gut microbiota, which predisposes to disease. Using non-obese diabetic mice that are genetically susceptible to T1D, we examined the effects of exposure to either continuous low-dose antibiotics or pulsed therapeutic antibiotics (PAT) early in life, mimicking childhood exposures. We found that in mice receiving PAT, T1D incidence was significantly higher, and microbial community composition and structure differed compared with controls. In pre-diabetic male PAT mice, the intestinal lamina propria had lower Th17 and Treg proportions and intestinal SAA expression than in controls, suggesting key roles in transducing the altered microbiota signals. PAT affected microbial lipid metabolism and host cholesterol biosynthetic gene expression. These findings show that early-life antibiotic treatments alter the gut microbiota and its metabolic capacities, intestinal gene expression and T-cell populations, accelerating T1D onset in non-obese diabetic mice.

Metabolic and metagenomic outcomes from early-life pulsed antibiotic treatment.

Mammalian species have co-evolved with intestinal microbial communities that can shape development and adapt to environmental changes, including antibiotic perturbation or nutrient flux. In humans, especially children, microbiota disruption is common, yet the dynamic microbiome recovery from early-life antibiotics is still uncharacterized. Here we use a mouse model mimicking paediatric antibiotic use and find that therapeutic-dose pulsed antibiotic treatment (PAT) with a beta-lactam or macrolide alters both host and microbiota development. Early-life PAT accelerates total mass and bone growth, and causes progressive changes in gut microbiome diversity, population structure and metagenomic content, with microbiome effects dependent on the number of courses and class of antibiotic. Whereas control microbiota rapidly adapts to a change in diet, PAT slows the ecological progression, with delays lasting several months with previous macrolide exposure. This study identifies key markers of disturbance and recovery, which may help provide therapeutic targets for microbiota restoration following antibiotic treatment.
