Population-level factors associated with maternal mortality in the United States, 1997–2012

Abstract Background In contrast to peer nations, the United States is experiencing rapid increases in maternal mortality. Trends in individual and population-level demographic factors and health trends may play a role in this change. Methods We analyzed state-level maternal mortality for the years 1997–2012 using multilevel mixed-effects regression grouped by state, using publicly available data including whether a state had adopted the 2003 U.S. Standard Certificate of Death, designed to simplify identification of pregnant and recently pregnant decedents. We calculated the proportion of the increase in maternal mortality attributable to specific factors during the study period. Results Maternal mortality was associated with higher population prevalence of obesity and high school non-completion among women of childbearing age; these factors explained 31.0% and 5.3% of the attributable increase in maternal mortality during the study period, respectively. Among delivering mothers, prevalence of diabetes (17.0%), attending fewer than 10 prenatal visits (4.9%), and African American race (2.0%) were also associated with higher maternal mortality, as was time-varying state adoption of the 2003 death certificate (31.1%). Conclusions Our findings indicate that, in addition to better case ascertainment of maternal deaths, adverse changes in chronic diseases, insufficient healthcare access, and social determinants of health represent identifiable risks for maternal mortality that merit prompt attention in population-directed interventions and health policies.https://deepblue.lib.umich.edu/bitstream/2027.42/145432/1/12889_2018_Article_5935.pd

Distal supports, capabilities, and growth‐focused recovery: A comparison of Housing First and the staircase continuum of care

Adults who have substantial histories of homelessness and complex support needs may feel ambivalent about integrating into their communities and find it difficult to do so. Being familiar to and recognized by others as a resident in a neighborhood or community are sources of “distal support” that provide individuals with feelings of belonging to their community and are important to recovery from homelessness. We hypothesized that individuals engaged with Housing First (HF) programs would report more distal support than individuals engaged with traditional homeless services (treatment as usual, TAU), and that distal support would predict more community integration, growth‐related recovery, and achieved capabilities. We analyzed data collected from homeless services users (n = 445) engaged with either HF or TAU in eight European countries. Measures included achieved capabilities, growth‐focused recovery, distal supports, and community integration. Serial mediation analyses confirmed our hypothesis that the effects of HF on growth‐related recovery and achieved capabilities are indirect, mediated by distal supports and community integration. Findings are discussed in relation to the importance of modeling the effects of HF on social and psychological outcomes as indirect and identifying important mediators that translate the effects of HF components on social and psychological outcomes. We also note the importance of case management activities that encourage clients to develop and sustain distal supports with others who live and work in their neighborhoods.info:eu-repo/semantics/publishedVersio

Designing prenatal care for low-income, black patients in urban settings using human centered design

Objective: Black and low-income pregnant patients face significant inequities in health care access and outcomes in the United States. Yet, these patients’ voices have been largely absent from designing improved prenatal care models. Our objective was to use Human Centered Design to examine patients’ and health care workers’ experiences with prenatal care delivery in a largely low-income, Black population, to inform future care innovations to improve access, quality, and outcomes. Study Design: Using snowball sampling, we conducted Human Centered Design-informed interviews with low-income, Black patients and health care workers in a large, urban setting. Interview questions addressed the first two Human Centered Design phases: 1) observation: understanding the problem from the end-user’s perspective, and 2) ideation: generating novel potential solutions. We assessed these questions for the three key components of prenatal care: medical care, anticipatory guidance, and psychosocial support. Results: Nineteen patients and 19 health care workers were interviewed. All patients were Black, and the majority had public insurance (17/19, 89.5%). Health care workers included doctors, midwives, breastfeeding counselors, doulas, and social workers. Participants affirmed the three goals of prenatal care. Participants reported failures of current prenatal care delivery and potential solutions for each of the three goals (medical care, anticipatory guidance, and psychosocial support) and two overarching categories: maternity care professionals and care structure. Participants reported in an ideal model, patients would have strong relationships with their maternity care professional who would be at the center of all prenatal care services. Additionally, care would be tailored to individual patients and use care navigators, flexible models, and colocation of services, to reduce barriers. Conclusion: Current prenatal care delivery fails to meet low-income, Black patients’ needs. Ideal prenatal care delivery includes more comprehensive, integrated services tailored to patients’ medical needs and preferences

Experiences With Prenatal Care Delivery Reported by Black Patients With Low Income and by Health Care Workers in the US: A Qualitative Study

IMPORTANCE: Black pregnant people with low income face inequities in health care access and outcomes in the US, yet their voices have been largely absent from redesigning prenatal care. OBJECTIVE: To examine patients\u27 and health care workers\u27 experiences with prenatal care delivery in a largely low-income Black population to inform care innovations to improve care coordination, access, quality, and outcomes. DESIGN, SETTING, AND PARTICIPANTS: For this qualitative study, human-centered design-informed interviews were conducted at prenatal care clinics with 19 low-income Black patients who were currently pregnant or up to 1 year post partum and 19 health care workers (eg, physicians, nurses, and community health workers) in Detroit, Michigan, between October 14, 2019, and February 7, 2020. Questions focused on 2 human-centered design phases: observation (understanding problems from the end user\u27s perspective) and ideation (generating novel potential solutions). Questions targeted participants\u27 experiences with the 3 goals of prenatal care: medical care, anticipatory guidance, and social support. An eclectic analytic strategy, including inductive thematic analysis and matrix coding, was used to identify promising strategies for prenatal care redesign. MAIN OUTCOMES AND MEASURES: Preferences for prenatal care redesign. RESULTS: Nineteen Black patients (mean [SD] age, 28.4 [5.9] years; 19 [100%] female; and 17 [89.5%] with public insurance) and 17 of 19 health care workers (mean [SD] age, 47.9 [15.7] years; 15 female [88.2%]; and 13 [76.5%] Black) completed the surveys. A range of health care workers were included (eg, physicians, doulas, and social workers). Although all affirmed the 3 prenatal care goals, participants reported failures and potential solutions for each area of prenatal care delivery. Themes also emerged in 2 cross-cutting areas: practitioners and care infrastructure. Participants reported that, ideally, care structure would enable strong ongoing relationships between patients and practitioners. Practitioners would coordinate all prenatal services, not just medical care. Finally, care would be tailored to individual patients by using care navigators, flexible models, and colocation of services to reduce barriers. CONCLUSIONS AND RELEVANCE: In this qualitative study of low-income, Black pregnant people in Detroit, Michigan, and the health care workers who care for them, prenatal care delivery failed to meet many patients\u27 needs. Participants reported that an ideal care delivery model would include comprehensive, integrated services across the health care system, expanding beyond medical care to also include patients\u27 social needs and preferences

Advice given by community members to pregnant women: a mixed methods study

Background Smoking and excess weight gain during pregnancy have been shown to have serious health consequences for both mothers and their infants. Advice from friends and family on these topics influences pregnant women’s behaviors. The purpose of our study was to compare the advice that community members give pregnant women about smoking versus the advice they give about pregnancy weight gain. Methods A survey was sent via text messaging to adults in a diverse, low-income primary care clinic in 2015. Respondents were asked what advice (if any) they have given pregnant women about smoking or gestational weight gain and their comfort-level discussing the topics. Descriptive statistics were used to characterize the sample population and to determine response rates. Open-ended responses were analyzed qualitatively using grounded theory analysis with an overall convergent parallel mixed methods design. Results Respondents (n = 370) were 77 % female, 40 % black, and 25 % reported education of high school or less. More respondents had spoken to pregnant women about smoking (40 %, n = 147) than weight gain (20 %, n = 73). Among individuals who had not discussed either topic (n = 181), more reported discomfort in talking about weight gain (65 %) compared to smoking (34 %; p < 0.0001). Advice about smoking during pregnancy (n = 148) was frequently negative, recommending abstinence and identifying smoking as harmful for baby and/or mother. Advice about weight gain in pregnancy (n = 74) revealed a breadth of messages, from reassurance about all weight gain (“Eat away” or “It’s ok if you are gaining weight”), to specific warnings against excess weight gain (“Too much was dangerous for her and the baby.”). Conclusions Many community members give advice to pregnant women. Their advice reveals varied perspectives on the effects of pregnancy weight gain. Compared to a nearly ubiquitous understanding of the harms of smoking during pregnancy, community members demonstrated less awareness of and willingness to discuss the harms of excessive weight gain. Beyond educating pregnant women, community-level interventions may also be important to ensure that the information pregnant women receive supports healthy behaviors and promotes the long-term health of both moms and babies

Working with people experiencing homelessness in Europe

In Europe, the widespread transition from the Traditional Staircase (TS) model to the Housing First (HF) model is transforming the way social service providers work with people experiencing homelessness. This study examined social service providers’ perspectives in both models regarding factors that facilitate or hinder their work. Data were collected through 17 photovoice projects involving 81 social service providers from eight European countries. The results show factors affecting social service providers’ work at three levels: systemic, organizational, and individual. Professionals in TS and HF identified similar topics; however, TS providers discussed more obstacles to work. Implications for practice are discussed.Comissão Européiainfo:eu-repo/semantics/publishedVersio

Evaluation of a minimally invasive glucose biosensor for continuous tissue monitoring

We describe here a minimally invasive glucose biosensor based on a microneedle array electrode fabricated from an epoxy-based negative photoresist (SU8 50) and designed for continuous measurement in the dermal compartment with minimal pain. These minimally invasive, continuous monitoring sensor devices (MICoMS) were produced by casting the structures in SU8 50, crosslinking and then metallising them with platinum or silver to obtain the working and reference electrodes, respectively. The metallised microneedle array electrodes were subsequently functionalised by entrapping glucose oxidase in electropolymerised polyphenol (PP) film. Sensor performance in vitro showed that glucose concentrations down to 0.5 mM could be measured with a response times (T90) of 15 s. The effect of sterilisation by Co60 irradiation was evaluated. In preparation for further clinical studies, these sensors were tested in vivo in a healthy volunteer for a period of 3–6 h. The sensor currents were compared against point measurements obtained with a commercial capillary blood glucometer. The epoxy MICoMS devices showed currents values that could be correlated with these

Monocarboxylate transporters (MCTs) in gliomas: expression and exploitation as therapeutic targets

Background. Gliomas exhibit high glycolytic rates, and monocarboxylate transporters (MCTs) play a major role in the maintenance of the glycolytic metabolism through the proton-linked transmembrane transport of lactate. However, their role in gliomas is poorly studied. Thus, we aimed to characterize the expression of MCT1, MCT4, and their chaperone CD 147 and to assess the therapeutic impact of MCT inhibition in gliomas. Methods. MCTs and CD 147 expressions were characterized by immunohistochemistry in nonneoplastic brain and glioma samples. The effect of CHC (MCT inhibitor) and MCT1 silencing was assessed in in vitro and in vivo glioblastoma models. Results. MCT1, MCT4, and CD 147 were overexpressed in the plasma membrane of glioblastomas, compared with diffuse astrocytomas and nonneoplastic brain. CHC decreased glycolytic metabolism, migration, and invasion and induced cell death in U251 cells (more glycolytic) but only affected proliferation in SW1088 (more oxidative). The effectiveness of CHC in glioma cells appears to be dependent on MCT membrane expression. MCT1 downregulation showed similar effects on different glioma cells, supporting CHC as an MCT1 inhibitor. There was a synergistic effect when combining CHC with temozolomide treatment in U251 cells. In the CAM in vivo model, CHC decreased the size of tumors and the number of blood vessels formed. Conclusions. This is the most comprehensive study reporting the expression of MCTs and CD 147 in gliomas. The MCT1 inhibitor CHC exhibited anti-tumoral and anti-angiogenic activity in gliomas and, of importance, enhanced the effect of temozolomide. Thus, our results suggest that development of therapeutic approaches targeting MCT1 may be a promising strategy in glioblastoma treatment.Life and Health Sciences Research Institute, University of Minho, Portugal; Fundacao para a Ciencia e Tecnologia [SFRH/BI/33503/2008, SFRH/BPD/69479/2010, SFRH/BD/36463/2007]info:eu-repo/semantics/publishedVersio

Functional diversity and co-operativity between subclonal populations of paediatric glioblastoma and diffuse intrinsic pontine glioma cells

The failure to develop effective therapies for pediatric glioblastoma (pGBM) and diffuse intrinsic pontine glioma (DIPG) is in part due to their intrinsic heterogeneity. We aimed to quantitatively assess the extent to which this was present in these tumors through subclonal genomic analyses and to determine whether distinct tumor subpopulations may interact to promote tumorigenesis by generating subclonal patient-derived models in vitro and in vivo. Analysis of 142 sequenced tumors revealed multiple tumor subclones, spatially and temporally coexisting in a stable manner as observed by multiple sampling strategies. We isolated genotypically and phenotypically distinct subpopulations that we propose cooperate to enhance tumorigenicity and resistance to therapy. Inactivating mutations in the H4K20 histone methyltransferase KMT5B (SUV420H1), present in <1% of cells, abrogate DNA repair and confer increased invasion and migration on neighboring cells, in vitro and in vivo, through chemokine signaling and modulation of integrins. These data indicate that even rare tumor subpopulations may exert profound effects on tumorigenesis as a whole and may represent a new avenue for therapeutic development. Unraveling the mechanisms of subclonal diversity and communication in pGBM and DIPG will be an important step toward overcoming barriers to effective treatments
