Pelvic Floor Disorders Among Minority Women: Differences in Prevalence, Severity and Health-Related Social Needs.

OBJECTIVE: To characterize prevalence and severity of pelvic floor disorders (PFDs) in various health care settings and to examine unmet health-related social needs (HRSN) among minority women. MATERIALS AND METHODS: Minority women with PFDs were recruited from our academic urogynecology clinic, a general urology clinic at our institution's safety net hospital, and a community outreach mobile clinic. Questions from the Urinary Distress Index-6, Pelvic Organ Prolapse Distress Inventory-6, and Female Genitourinary Pain Index were used to identify patients with stress urinary incontinence, overactive bladder (OAB), and chronic pelvic pain syndrome (CPPS). RESULTS: Sixty-one (46.6%) women identified as Hispanic, 53 (40.4%) as Black, and 17 (12.9%) as Other. Overall, self-reported PFDs included stress urinary incontinence in 45%, OAB in 74.8%, and CPPS in 24.4% of women. Hispanic women were more likely to report OAB symptoms, compared to Black women (odds ratio (OR) 3.4 [1.2-10.2], P = .03) or Other women (OR = 5.1 [1.3-20.4], P = .02). Participants held a median of 5 unmet HRSN. Minority women facing issues with family and community support, transportation, and utilities were more likely to report CPPS symptoms, compared to those without psychosocial issues (support OR: 4.8 [1.7-13.7], P = .002; transportation OR: 2.0 [1.0-8.2], P = .05; utility OR: 7.0 [1.9-28.1], P = .005). CONCLUSION: Minority women with PFDs may have several unmet HRSNs which impact their ability to receive appropriate medical care. Our findings may assist in the development of effective strategies to improve health care outcomes for women dealing with PFDs.

A Mini-Review of Strategies for Recruiting Older African Americans to Alzheimer's Disease Research.

African Americans experience higher incidence and prevalence of Alzheimer's disease (AD). Yet, they continue to be underrepresented in AD research, limiting the ability to generalize findings to the increasingly diverse US population. To reduce AD disparities, targeted efforts are needed to increase the representation of African Americans in AD research. This mini review identified evidence-based strategies that increased research participation among older African Americans. Four recruitment strategies emerged from eight published peer-reviewed studies that directly evaluated the effectiveness of strategies aimed at increasing the number of African American participants in Alzheimer's research. The strategies include community outreach and education, face-to-face discussions, remote access, and referral and partnership with local organizations. Across different locations, these strategies increased the number of African Americans enrolled into AD research, the number of people that signed up to donate their brains for AD research upon death, and the knowledge and perception of AD in the communities. Targeted efforts are effective in increasing AD research participation among older African Americans, especially when combined with approaches that emphasize transparency and mutual trust and involve the community as stakeholders in the research process.

Genotypic analysis of the female BPH/5 mouse, a model of superimposed preeclampsia.

Animal models that recapitulate human diseases and disorders are widely used to investigate etiology, diagnosis, and treatment of those conditions in people. Disorders during pregnancy are particularly difficult to explore as interventions in pregnant women are not easily performed. Therefore, models that allow for pre-conception investigations are advantageous for elucidating the mechanisms involved in adverse pregnancy outcomes that are responsible for both maternal and fetal morbidity, such as preeclampsia. The Blood Pressure High (BPH)/5 mouse model has been used extensively to study the pathogenesis of preeclampsia. The female BPH/5 mouse is obese with increased adiposity and borderline hypertension, both of which are exacerbated with pregnancy making it a model of superimposed preeclampsia. Thus, the BPH/5 model shares traits with a large majority of women with pre-existing conditions that predisposes them to preeclampsia. We sought to explore the genome of the BPH/5 female mouse and determine the genetic underpinnings that may contribute to preeclampsia-associated phenotypes in this model. Using a whole genome sequencing approach, we are the first to characterize the genetic mutations in BPH/5 female mice that make it unique from the closely related BPH/2 model and the normotensive background strain, C57Bl/6. We found the BPH/5 female mouse to be uniquely different from BPH/2 and C57Bl/6 mice with a genetically complex landscape. The majority of non-synonymous consequences within the coding region of BPH/5 females were missense mutations found most abundant on chromosome X when comparing BPH/5 and BPH/2, and on chromosome 8 when comparing BPH/5 to C57Bl/6. Genetic mutations in BPH/5 females largely belong to immune system-related processes, with overlap between BPH/5 and BPH/2 models. Further studies examining each gene mutation during pregnancy are warranted to determine key contributors to the BPH/5 preeclamptic-like phenotype and to identify genetic similarities to women that develop preeclampsia.

Intensity of Vasopressor Therapy and In-Hospital Mortality for Infants and Children: An Opportunity for Counseling Families.

CONTEXT: Most pediatric deaths occur in an intensive care unit, and treatment specific predictors of mortality could help clinicians and families make informed decisions. OBJECTIVE: To investigate whether the intensity of vasopressor therapy for pediatric patients, regardless of diagnosis, predicts in-hospital mortality. METHODS: Single-center, retrospective medical chart review of children aged 0-17 who were admitted between 2005 and 2015 at a pediatric tertiary care center in the U.S. and received any vasopressor medication-dopamine, dobutamine, epinephrine, vasopressin, norepinephrine, or hydrocortisone. RESULTS: During the 10-year period, 1654 patients received at least one vasopressor medication during a hospitalization. Median age at the time of hospitalization was three months, and the median duration of hospitalization was 23 days; 8% of patients had two to five hospitalizations in which they received vasopressors. There were 176 total patients who died while receiving vasopressors; most (93%) died during their first hospitalization. The most common diagnosis was sepsis (34%), followed by congenital heart disease (17%). Dopamine was the most commonly prescribed first-line vasopressor (70%), and hydrocortisone was the most commonly prescribed second-line vasopressor (49%) for all pediatric patients. The incidence of mortality rose sequentially with escalating vasopressor support, increasing from under 10% with the first vasopressor to 48% at the maximum number of agents. The odds of death almost doubled with the addition of each new vasopressor. CONCLUSIONS: The intensity of vasopressor therapy for pediatric patients, regardless of diagnosis, is associated with in-hospital mortality; vasopressor escalation should trigger intensive palliative care supports.

Endothelial Jagged1 Antagonizes Dll4/Notch Signaling in Decidual Angiogenesis during Early Mouse Pregnancy.

Maternal spiral arteries and newly formed decidual capillaries support embryonic development prior to placentation. Previous studies demonstrated that Notch signaling is active in endothelial cells of both decidual capillaries and spiral arteries, however the role of Notch signaling in physiologic decidual angiogenesis and maintenance of the decidual vasculature in early mouse pregnancy has not yet been fully elucidated. We used the Cdh5-CreERT2;Jagged1(Jag1)flox/flox (Jag1∆EC) mouse model to delete Notch ligand, Jag1, in maternal endothelial cells during post-implantation, pre-placentation mouse pregnancy. Loss of endothelial Jag1 leads to increased expression of Notch effectors, Hey2 and Nrarp, and increased endothelial Notch signaling activity in areas of the decidua with remodeling angiogenesis. This correlated with an increase in Dll4 expression in capillary endothelial cells, but not spiral artery endothelial cells. Consistent with increased Dll4/Notch signaling, we observed decreased VEGFR2 expression and endothelial cell proliferation in angiogenic decidual capillaries. Despite aberrant Dll4 expression and Notch activation in Jag1∆EC mutants, pregnancies were maintained and the decidual vasculature was not altered up to embryonic day 7.5. Thus, Jag1 functions in the newly formed decidual capillaries as an antagonist of endothelial Dll4/Notch signaling during angiogenesis, but Jag1 signaling is not necessary for early uterine angiogenesis.

Eastern Equine Encephalitis and YouTube videos: A content analysis.

BACKGROUND: Eastern Equine Encephalitis virus (EEEV) infections among humans are rare, but can result in severe consequences. YouTube can serve as a platform for EEEV health education. This study aims to assess the characteristics of the top EEEV-related YouTube videos, and whether their informational contents vary by uploading source. METHODS: On August 15, 2016, we searched YouTube.com for the top 100 videos by number of views featuring "Eastern Equine Encephalitis". We manually coded and statistically analyzed the contents, source of uploads and meta-data of 100 most viewed EEEV-related YouTube videos. Univariate logistic regression was applied to identify if videos of different sources (consumer, professional, and news) differed in their contents. RESULTS: Excluding one video, 21 Consumer, 9 Professional, and 69 News videos were analyzed (N = 99). Compared with news-videos, consumer-videos are less likely to mention the geography of EEEV transmission (OR = 0.21, p < 0.01); professional-videos are more likely to mention other types of encephalitis (OR = 27.50, p < 0.01), and to mention horses only (OR = 8.5, p < 0.01). CONCLUSIONS: Professional videos provided the most comprehensive information. However, few videos from professionals made it to the top 100 list. The untapped potential of YouTube as a unique platform to disseminate EEEV information deserves the attention of public health professionals.
