Patterns of enrollment in a New Orleans women's substance use rehabilitation center.

BACKGROUND: Research has told us little about the demographics of individuals entering substance use programs in New Orleans, Louisiana, especially women accessing treatment programs. Considering that New Orleans is a predominantly Black city and both substance use treatment and research have historically left out Black patients, this study evaluates the age, race, insurance status, education level, and substance of choice for patients entering Grace House Rehabilitation Center, an all women nonprofit substance use treatment program in New Orleans, Louisiana. METHODS: Since 2013, Tulane School of Medicine students have held weekly primary care clinics at Grace House. This study used the clinic's patients' handwritten intake forms to collect demographic variables between 2013 and 2019. The study then evaluated the data using descriptive statistical analysis. RESULTS: The study analyzed 743 patient charts. We found that 78.4% of women admitted to Grace House were white (n = 627), and 14.5% of women were Black (n = 1160). The study excluded all other racial and ethnic groups due to the groups' small sample size. The average age at admittance was 34.7 years for both white and Black women; however, the average age for Black women was 42 years old. The 743 women studied reported the use of 1123 unique substances. While more than half of both populations used only one type of substance, Black women more commonly used only one substance. CONCLUSION: New Orleans is a predominantly Black community, yet young Black women are largely missing from the patient population that we studied. While multiple reasons exist for the lack of Black women in this population, Black substance-using women are clearly left out of the life-saving treatment that they deserve. The medical community must investigate further to make genuine, impactful changes to how substance use treatment is accessed by all minority groups, but especially Black women.

Aerodigestive sampling reveals altered microbial exchange between lung, oropharyngeal, and gastric microbiomes in children with impaired swallow function.

BACKGROUND: Children with oropharyngeal dysphagia have impaired airway protection mechanisms and are at higher risk for pneumonia and other pulmonary complications. Aspiration of gastric contents is often implicated as a cause for these pulmonary complications, despite being supported by little evidence. The goal of this study is to determine the relative contribution of oropharyngeal and gastric microbial communities to perturbations in the lung microbiome of children with and without oropharyngeal dysphagia and aspiration. METHODS: We conducted a prospective cohort study of 220 patients consecutively recruited from a tertiary aerodigestive center undergoing simultaneous esophagogastroduodenoscopy and flexible bronchoscopy. Bronchoalveolar lavage, gastric and oropharyngeal samples were collected from all recruited patients and 16S sequencing was performed. A subset of 104 patients also underwent video fluoroscopic swallow studies to assess swallow function and were categorized as aspiration/no aspiration. To ensure the validity of the results, we compared the microbiome of these aerodigestive patients to the microbiome of pediatric patients recruited to a longitudinal cohort study of children with suspected GERD; patients recruited to this study had oropharyngeal, gastric and/or stool samples available. The relationships between microbial communities across the aerodigestive tract were described by analyzing within- and between-patient beta diversities and identifying taxa which are exchanged between aerodigestive sites within patients. These relationships were then compared in patients with and without aspiration to evaluate the effect of aspiration on the aerodigestive microbiome. RESULTS: Within all patients, lung, oropharyngeal and gastric microbiomes overlap. The degree of similarity is the lowest between the oropharynx and lungs (median Jensen-Shannon distance (JSD) = 0.90), and as high between the stomach and lungs as between the oropharynx and stomach (median JSD = 0.56 for both; p = 0.6). Unlike the oropharyngeal microbiome, lung and gastric communities are highly variable across people and driven primarily by person rather than body site. In patients with aspiration, the lung microbiome more closely resembles oropharyngeal rather than gastric communities and there is greater prevalence of microbial exchange between the lung and oropharynx than between gastric and lung sites (p = 0.04 and 4x10-5, respectively). CONCLUSIONS: The gastric and lung microbiomes display significant overlap in patients with intact airway protective mechanisms while the lung and oropharynx remain distinct. In patients with impaired swallow function and aspiration, the lung microbiome shifts towards oropharyngeal rather than gastric communities. This finding may explain why antireflux surgeries fail to show benefit in pediatric pulmonary outcomes.
