RESUMEN

BACKGROUND: The purpose of this study includes: 1) identifying classes of substance-related needs among Black women, and 2) examining the effect of substance-related need classes and culturally-relevant factors on Black women's use of substance use disorder (SUD) treatment and mutual support groups. METHODS: As part of a longitudinal cohort study, Black women were recruited in prison nearing release, on probation, and in the community without involvement in the criminal legal system (CLS, n=565) and followed-up at 18-months. We conducted a baseline latent class analysis of substance-related needs among Black women. Logistic regression models adjusted for culturally-relevant factors to predict the use of treatment and frequency of mutual support group participation over 18-months among Black women who use drugs. RESULTS: Four classes by level of needs were found: low, daily marijuana use, high mental health, and high comorbidity. During the 18-month follow-up, women characterized by the high comorbidity need class and with higher scores of religious well-being were more likely to frequently participate in mutual support groups. Non-CLS-involved women were less likely to engage with both treatment and mutual support groups than women from the prison sample at 18-months. CONCLUSIONS: This study highlights four distinct classes of substance-related needs among Black women, highlighting the complex patterns of behavior and within-racial group differences among Black women. Black women with high comorbidity needs were more likely to participate in mutual support groups, but the latent classes did not predict SUD treatment indicating other non-medical and social contextual need factors may be at play.

RESUMEN

Thirty-four crossbred dairy cows were observed on pasture six times per week from June to August 2014 at the University of Minnesota West Central Research and Outreach Center grazing dairy in Morris, MN, for defensive behaviors in response to three species of muscid flies. Counts of stable flies (Stomoxys calcitrans (L.)), horn flies (Haematobia irritans (L.)), and face flies (Musca autumnalis DeGeer) were recorded before and after pasture observation. Individual cows were monitored for 5 min intervals to observe the frequencies of five different defensive behaviors: front and back leg stomps, head tosses, skin twitches, and tail swishes. Fly numbers averaged 5 stable flies per leg, 37 horn flies per side, and 1 face fly per face during the study. The fly counts and behavior frequencies increased with ambient temperature. The results showed a very strong relationship between the numbers of flies and numbers of defensive behaviors, though correlations between specific flies and behaviors were low. Younger cows had fewer stable flies and horn flies than older cows. The thresholds of flies to lower production for pastured organic dairy cows may be greater than 5 for stable flies, 37 for horn flies, and 1 for face flies.

RESUMEN

Non-bacterial thrombotic endocarditis, characterised by sterile vegetations, is commonly caused by systemic lupus erythematosus and is known to be complicated with embolic cerebrovascular disease. Embolic myocardial infarction with non-bacterial thrombotic endocarditis is extremely rare. We report a case of ventricular fibrillation arrest from presumed coronary embolisation in non-bacterial thrombotic endocarditis. While there are no standardised guidelines on the management of embolic myocardial infarction in endocarditis, it requires a multidisciplinary approach unique for every encountered clinical scenario.

RESUMEN

PURPOSE: The goal of this study was to evaluate how rural/urban status and other risk factors alter women's odds of severe maternal morbidity (SMM) at delivery. METHODS: This study used 48,608 Kentucky resident delivery hospitalization records from 2017. We used multiple logistic regression with interaction terms to evaluate the moderating effect of rural/urban residence with other risk factors. We reported adjusted odds ratios (aORs) and 95% confidence intervals (CIs) as measures for association with the outcome of SMM at delivery. FINDINGS: The percentage of delivery hospitalizations with SMM was higher for women with rural (2.4%) versus metro (1.1%) or metro-adjacent (1.5%) residence (p < .001). Rural status moderated the effect of anemia on SMM. The aOR for SMM for women with anemia versus those without was 8.56 (CI: 4.89-14.97) in rural areas, two times higher than in metro areas (aOR 3.87; CI: 3.09-4.86). Kentucky Appalachian region (aOR 1.90; CI: 1.46-2.47), Black race (aOR 1.30; CI: 1.02-1.66), history of cesarean section (aOR 1.28; CI: 1.07-1.52), hypertension (aOR 10.55; CI: 5.67-19.62), and opioid use (aOR 1.72; CI: 1.19-2.47) were significantly associated with SMM. CONCLUSION: Rural women in Kentucky are at an increased risk for SMM. Quality and safety programming should specifically address the needs of isolated subpopulations. Women living in rural areas are more likely to experience SMM given an anemia diagnosis. The underlying cause and clinical management of anemia may differ between rural and urban areas.
