This secondary analysis examines low-income, street-identified single Black mothers aged 18 to 35 years in Wilmington, Delaware. This study is guided by the following question: To what extent do family composition and criminal record/street activity shape notions of Black single motherhood? “Sites of resilience” theory informs this study by providing a reconceptualization of street life and the phenomenological experiences of street-identified Black women. This analysis draws on 310 surveys, 6 individual interviews, 3 dual interviews, 2 group interviews, and extensive field observations. Findings reveal how these women experience single motherhood within the context of blocked opportunity and structural inequality. Results also indicate that most women socially reproduced childhood attitudes and conditions, including “fatherless” homes and single motherhood. Use and sales of narcotics and incarceration were primary factors for why their children’s father didn’t reside in the home. Findings also suggest that number of children, arrest and incarceration rates, and educational and employment statuses are predictive of marital status in the women.

Abstract Uptake of influenza vaccine among pregnant women remains low. We investigated whether unvaccinated pregnant women were clustered geographically and determined factors associated with failure to vaccinate using spatial and multivariate logistic regression analyses. Pregnant women who were members of Kaiser Permanente Northern California in 2015 or 2016 were included in the study. More than half (53%) of the 77,607 included pregnant women were unvaccinated. Spatial analysis identified 5 clusters with a high prevalence of unvaccinated pregnant women. The proportion of unvaccinated women ranged from 57% to 75% within clusters as compared with 51% outside clusters. In covariate-adjusted analyses, residence in a cluster was associated with a 41% increase in the odds of being unvaccinated (odds ratio (OR) = 1.41, 95% confidence interval (CI): 1.36, 1.46). The odds of being unvaccinated were greater for Black women (OR = 1.58, 95% CI: 1.49, 1.69), Hispanic women (OR = 1.15, 95% CI: 1.05, 1.25), women with subsidized health insurance (OR = 1.18, 95% CI: 1.11, 1.24), women with fewer than 5 prenatal-care visits (OR = 1.85, 95% CI: 1.60, 2.16), and neighborhoods with a high deprivation index (fourth quartile vs. first: OR = 1.14, 95% CI: 1.07, 1.21). In conclusion, unvaccinated pregnant women were clustered geographically and by key sociodemographic factors. These findings suggest that interventions to increase influenza vaccine coverage among pregnant women are needed, particularly in vulnerable populations.

Large Quantum

A formalism is developed for describing approximate classical behavior in finite (but possibly large) quantum systems. This is done in terms of a structure common to classical and quantum mechanics, viz. a Poisson space with a transition probability. Both the limit where ħ→0 in a fixed finite system and the limit where the size of the system goes to infinity are incorporated. In either case, classical behavior is seen only for certain observables and in a restricted class of states.

Despite high rates of Uterine Leiomyomata (UL) diagnoses found in black women, there is paucity in research. Therefore, this study aimed at estimating the prevalence and burden of symptomatic UL among women in Imo State, Nigeria. The study is a descriptive cross-sectional hospital-based study that was carried out in Radiology, Obstetrics and Gynaecology departments of three hospitals and two diagnostic Centres covering the three senatorial zones in Imo State. The research was based on a convenience sampling of 2965 women within the age group of 16 to 49 that reside in the 3 senatorial zones referred for an ultrasound scan and who met the selection criteria within the period of study. Eligible and consented women responded to the questionnaire and underwent a transabdominal ultrasound. The data were analysed with the statistical program PASW 18 and p values < 0.05 were taken to be statistically significant. Weighted means and percentages were reported and prevalence across the senatorial zones was examined. Symptom burden among women with and without uterine fibroids was compared using weighted logistic regressions. Of 2965 respondents who met study inclusion criteria, a total of 652(22.0%) were diagnosed having UL while 2313 (78.0%) do not have the disease. Hence the overall prevalence of UL at clinics/Diagnostic centres in Imo State was 22%. Uterine fibroids impose a heavy burden on women aged 16–49 years in Imo State. It represents an important gynecologic pathology in women due to its relatively high prevalence and its significant impact on patient’s quality of life.
