Perceptions about prenatal care: views of urban vulnerable groups

BACKGROUND: In the United States, infant mortality rates remain more than twice as high for African Americans as compared to other racial groups. Lack of adherence to prenatal care schedules in vulnerable, hard to reach, urban, poor women is associated with high infant mortality, particularly for women who abuse substances, are homeless, or live in communities having high poverty and high infant mortality. This issue is of concern to the women, their partners, and members of their communities. Because they are not part of the system, these womens' views are often not included in other studies. METHODS: This qualitative study used focus groups with four distinct categories of people, to collect observations about prenatal care from various perspectives. The 169 subjects included homeless women; women with current or history of substance abuse; significant others of homeless women; and residents of a community with high infant mortality and poverty indices, and low incidence of adequate prenatal care. A process of coding and recoding using Ethnograph and counting ensured reliability and validity of the process of theme identification. RESULTS: Barriers and motivators to prenatal care were identified in focus groups. Pervasive issues identified were drug lifestyle, negative attitudes of health care providers and staff, and non-inclusion of male partners in the prenatal experience. CONCLUSIONS: Designing prenatal care relevant to vulnerable women in urban communities takes creativity, thoughtfulness, and sensitivity. System changes recommended include increased attention to substance abuse treatment/prenatal care interaction, focus on provider/staff attitudes, and commitment to inclusion of male partners

The ACCESS study a Zelen randomised controlled trial of a treatment package including problem solving therapy compared to treatment as usual in people who present to hospital after self-harm: study protocol for a randomised controlled trial

<p>Abstract</p> <p>Background</p> <p>People who present to hospital after intentionally harming themselves pose a common and important problem. Previous reviews of interventions have been inconclusive as existing trials have been under powered and done on unrepresentative populations. These reviews have however indicated that problem solving therapy and regular written communications after the self-harm attempt may be an effective treatment. This protocol describes a large pragmatic trial of a package of measures which include problem solving therapy, regular written communication, patient support, cultural assessment, improved access to primary care and a risk management strategy in people who present to hospital after self-harm using a novel design.</p> <p>Methods</p> <p>We propose to use a double consent Zelen design where participants are randomised prior to giving consent to enrol a large representative cohort of patients. The main outcome will be hospital attendance following repetition of self-harm, in the 12 months after recruitment with secondary outcomes of self reported self-harm, hopelessness, anxiety, depression, quality of life, social function and hospital use at three months and one year.</p> <p>Discussion</p> <p>A strength of the study is that it is a pragmatic trial which aims to recruit large numbers and does not exclude people if English is not their first language. A potential limitation is the analysis of the results which is complex and may underestimate any effect if a large number of people refuse their consent in the group randomised to problem solving therapy as they will effectively cross over to the treatment as usual group. However the primary analysis is a true intention to treat analysis of everyone randomised which includes both those who consent and do not consent to participate in the study. This provides information about how the intervention will work in practice in a representative population which is a major advance in this study compared to what has been done before.</p> <p>Trial registration</p> <p>Australia and New Zealand Clinical Trials Register (ANZCTR): <a href="http://www.anzctr.org.au/ACTRN12609000641291.aspx">ACTRN12609000641291</a></p

sodC-Based Real-Time PCR for Detection of Neisseria meningitidis

Real-time PCR (rt-PCR) is a widely used molecular method for detection of Neisseria meningitidis (Nm). Several rt-PCR assays for Nm target the capsule transport gene, ctrA. However, over 16% of meningococcal carriage isolates lack ctrA, rendering this target gene ineffective at identification of this sub-population of meningococcal isolates. The Cu-Zn superoxide dismutase gene, sodC, is found in Nm but not in other Neisseria species. To better identify Nm, regardless of capsule genotype or expression status, a sodC-based TaqMan rt-PCR assay was developed and validated. Standard curves revealed an average lower limit of detection of 73 genomes per reaction at cycle threshold (Ct) value of 35, with 100% average reaction efficiency and an average R2 of 0.9925. 99.7% (624/626) of Nm isolates tested were sodC-positive, with a range of average Ct values from 13.0 to 29.5. The mean sodC Ct value of these Nm isolates was 17.6±2.2 (±SD). Of the 626 Nm tested, 178 were nongroupable (NG) ctrA-negative Nm isolates, and 98.9% (176/178) of these were detected by sodC rt-PCR. The assay was 100% specific, with all 244 non-Nm isolates testing negative. Of 157 clinical specimens tested, sodC detected 25/157 Nm or 4 additional specimens compared to ctrA and 24 more than culture. Among 582 carriage specimens, sodC detected Nm in 1 more than ctrA and in 4 more than culture. This sodC rt-PCR assay is a highly sensitive and specific method for detection of Nm, especially in carriage studies where many meningococcal isolates lack capsule genes

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Genomic investigations of unexplained acute hepatitis in children

Since its first identification in Scotland, over 1,000 cases of unexplained paediatric hepatitis in children have been reported worldwide, including 278 cases in the UK1. Here we report an investigation of 38 cases, 66 age-matched immunocompetent controls and 21 immunocompromised comparator participants, using a combination of genomic, transcriptomic, proteomic and immunohistochemical methods. We detected high levels of adeno-associated virus 2 (AAV2) DNA in the liver, blood, plasma or stool from 27 of 28 cases. We found low levels of adenovirus (HAdV) and human herpesvirus 6B (HHV-6B) in 23 of 31 and 16 of 23, respectively, of the cases tested. By contrast, AAV2 was infrequently detected and at low titre in the blood or the liver from control children with HAdV, even when profoundly immunosuppressed. AAV2, HAdV and HHV-6 phylogeny excluded the emergence of novel strains in cases. Histological analyses of explanted livers showed enrichment for T cells and B lineage cells. Proteomic comparison of liver tissue from cases and healthy controls identified increased expression of HLA class 2, immunoglobulin variable regions and complement proteins. HAdV and AAV2 proteins were not detected in the livers. Instead, we identified AAV2 DNA complexes reflecting both HAdV-mediated and HHV-6B-mediated replication. We hypothesize that high levels of abnormal AAV2 replication products aided by HAdV and, in severe cases, HHV-6B may have triggered immune-mediated hepatic disease in genetically and immunologically predisposed children

Building capacity for collaborative research between basic scientists and underrepresented communities in cancer research

Purpose: Basic science research is critical for understanding biological mechanisms essential to advances in cancer prevention, diagnoses and treatment. However, most of this research is conducted outside of the purview of community observation or input, leaving these research processes mysterious and subsequent findings disconnected from the communities they intend to benefit. This paper discusses strategies to build capacity for collaborations between basic scientists and Hispanic community members at the University of Arizona Cancer Center (UACC). Methods: Through partnership of the Cancer Biology Program and Office of Community Outreach and Engagement both at UACC, the Research Outreach for Southern Arizona (ROSA) program was developed as a way to forward the following strategies to build capacity for collaboration: forming a community working group, launching a community and student ambassador program, hosting scientific cafés and developing a community-based survey. Results: The strategies underpinning the ROSA program have been integral in bridging dialogue between basic scientists and the community and fostering bidirectional learning opportunities. Each of the strategies presented have documented successes and based on the lessons learned, they have evolved into productive and integral parts of UACC’s overall strategy of bridging scientific research and communities. Conclusion: While the strategies discussed are evolving, they help foster dialogue and exchange between basic scientists and community members that demystifies basic science research and facilitates culturally tailored approaches to address health disparities of vulnerable communities. These strategies also have the potential to shift cancer research into a paradigm that is more collaborative and transformative.12 month embargo; first published 03 June 2023This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Geologic Cross Section of the North American Plate near 36° Latitude, Part I: Western U.S. from the Pacific Oceanic Crust to the Mid-Continent

A geologic cross section across the southern United States near latitude 36° provides an up-to-date working model for the structure of the North American plate and its interactions with the upper mantle asthenosphere. The American Geological Institute, in dedication to Marcus E. Milling, will produce an annotated 1:1 M-scale technical cross section across the continent useful to researchers, and a 1:2 M-scale geological cross section useful for K-12, the general public, and introductory college geology classes. The visual product will consist of an oblique DEM, to add a 3D component, along with the cross section at 4:1 vertical exaggeration that will portray the geology to depths of 250 km. The cross section extends from the eastern to the western margin of the North American plate. The western half consists of a tectonically active domain in which plate boundary deformation is inducing and interacting with a complex intraplate deformational field in a 1000-km-wide uplifted orogenic plateau that extends as far east as the Great Plains. This wide deforming plate margin domain provides a field laboratory for understanding the structure and evolution of continental plates. The western segment of the GeCSNAP cross section extends from the coastal Franciscan accretionary complex, across the Salinia forearc microplate, the San Andreas fault, the Cretaceous forearc basin, the Sierra Nevada Mesozoic magmatic arc, the eastern California shear zone of the Basin and Range province, the Colorado Plateau, the Rio Grand rift, the Rocky Mountains, and the western Great Plains. A theme of the cross section is dynamic mantle flow under the western U.S. where lithosphere is sinking beneath the Sierra Nevada and asthenosphere is upwelling in the Basin and Range, near the western edge of the Colorado Plateau, and in the Rio Grande rift
