Engagement: an indicator of difference in the perceptions of antenatal care for pregnant women from diverse socioeconomic backgrounds

Background Socioeconomically deprived women are at greater risk of adverse pregnancy outcomes. Research tends to focus on access of services. Yet access may not equate with the equity of services for women from different socioeconomic backgrounds. Objectives To determine whether pregnant women’s perceptions of antenatal provision differed in relation to their socioeconomic deprivation ranking (determined by the Scottish Index of Multiple Deprivation 2006). Design A longitudinal, qualitative study with comparative antenatal case studies between January 2007 and April 2009. Setting/Participants Cases were primigravida women from ‘least deprived’ (n = 9) and ‘most deprived’ (n = 12) geographical areas within one local authority in Scotland. Analysis Data were analysed using case study replication analysis. Results There was little difference in access to antenatal services between the ‘least’ and ‘most’ deprived groups. Perception of care differed in relation to the level of ‘engagement’ (defined using constructs of: language and personalization of care; power and relationships; and health literacy). Engagement was evidenced in most of the ‘least deprived’ cases and almost none of the ‘most deprived’ cases. Specifically, socioeconomically deprived women described less evidence of personal connection to their own care, effective communication and the opportunity for shared decision making. Conclusion In women from socioeconomically deprived areas, access may be a less useful indicator than engagement when assessing antenatal service quality. As engagement levels may be one method by which to predict and improve health outcomes, a more equitable antenatal service may need to be developed through the early identification of those women at risk of non‐engagement.     

Manufacturing Better Outcomes in Cardiovascular Intervention: 3D Printing in Clinical Practice Today

Purpose of review

Describe and evaluate the integration of 3D printing-related innovations into current cardiovascular treatment paradigms and examine the state of regulatory and reimbursement hurdles ahead.

Recent findings

Mounting years of clinical experience have established the utility of printed models of patient anatomy in numerous treatment and teaching scenarios, most notably as pre- and intra-procedural planning tools guiding decision-making for congenital heart disease and catheter-based interventions. In part due to a continued lack of reimbursement and under-defined (and slow to evolve) regulatory status, these use cases remain largely investigational even as they grow increasingly routine. Patients, physicians, and/or imaging centers therefore remain burdened by the associated cost to create such models, and the perceptual and decision-making enhancements, while demonstrable and significant, still may not clearly or independently justify a potentially high cost.Simulation and implantable device applications may represent a deeper well of unrealized value in cardiovascular intervention; however, further development of these applications relies on—and is throttled by—progress in material science and tissue-engineering research. The relevance of simulation applications in recent years is also now in competition with digital analogs including augmented and virtual reality. Innovative incorporation of alternative manufacturing processes such as porous scaffold infusion, injection molding, and vascular mesh forming can provide immediate access to more realistic tissue-mimicking materials and custom implantable devices, while comparable and directly printable materials continue to be developed. Tissue-engineering applications remain years if not decades away from a more substantive role in translatable clinical research. Regulatory challenges associated with in-house manufacture of implantable investigational devices are complex and subject to change, and the success of some in navigating these hurdles in non-cardiovascular applications is instructive and encouraging.

Summary

Complex geometries characterizing cardiovascular anatomy are an ideal use case for translating the perceptual advantages of printed models of patient anatomy into better decision-making, especially so in the setting of congenital or post-surgical anatomy. Procedural planning applications take further advantage of the demonstrably robust dimensional reproduction of patient anatomy, with notably rapid integration into surgical and catheter-based intervention workflows. Despite a continued lack of codification in the healthcare system, 2018 could be a milestone year for 3D printing services, pending a successful application for a CPT Category III designation.

     

Severe intravascular hemolysis following mitral valve repair

We report two cases of severe intravascular hemolysis (IVH) following mitral valve repair using a Cosgrove-Edwards ring. In both cases, the degree of mitral regurgitation (MR) seen postoperatively worsened significantly compared to intraoperative transesophageal echocardiogram. Both patients required reoperation with mitral valve replacement with immediate resolution of the hemolysis. We hypothesize that the mitral regurgitation in the setting of an inadequate mitral valve repair is responsible for the hemolysis and propose various mechanisms to explain this pathophysiology. Although IVH remains a rare complication following mitral valve repair, possible screening recommendations should be considered for early detection and treatment given the growing number of mitral valve repairs being performed.     

Prevalence and Risk Factors Associated with HIV Infection Among Men Having Sex with Men in Ho Chi Minh City, Vietnam

To learn more about risk behaviors among men who have sex with men (MSM) in Vietnam and their prevalence of HIV, we conducted a study among MSM in Ho Chi Minh City (HCMC) to determine HIV-1 prevalence and behaviors associated with infection. This consisted of formative (35 MSM) and cross-sectional (600 MSM) studies at 72 sites, including 75 transvestites, 55 bisexuals, 10 sex workers, and 460 other MSM. Only 5.3% cohabited with a wife/girlfriend, but 30% reported ever having sex with a female. Prevalence of HIV was 8%, ranging from 33% in sex workers to 7% among transvestites and other MSM. Injecting drugs, selling sex, being 20–40 years old, having less than 6 years of education, and having more than five male anal sex partners in the past month were associated with being HIV-infected. MSM are an HIV bridge group, and should be included in sentinel surveillance. Targeted interventions should be implemented.     

Insulin receptors on leukemia and lymphoma cells

Tumor cells obtained from leukemia and lymphoma patients were investigated for specific insulin receptors. Using radioactive 125I- labeled insulin, specific insulin binding sites were demonstrated on most acute lymphocytic leukemia (ALL) and acute myelocytic leukemia (AML) cells, including acute promyelocytic leukemia (APL), chronic myelocytic leukemia (CML), and acute monocytic leukemia (AMoL) cells. Insulin receptors were not found on chronic lymphocytic leukemia (CLL) and malignant lymphoma (ML) cells. Specific insulin binding sites were also found on monocytes and thymocytes after treatment with phytohemagglutinin (PHA-P), but not on inactivated tonsil cells, peripheral blood lymphocytes, or thymocytes. There was no inverse correlation between the content of insulin receptors and the basal level of circulating insulin. These data suggest that the insulin receptor may be a new marker of acute leukemia and chronic myelocytic leukemia.     

Blood-based immunoassay of tau proteins for early diagnosis of Alzheimer's disease using surface plasmon resonance fiber sensors

We present the immunoassay of tau proteins (total tau and phosphorylated tau) in human sera using surface plasmon resonance (SPR) fiber sensors. This assay aimed at harvesting the advantages of using both SPR fiber sensors and a blood-based assay to demonstrate label-free point-of-care-testing (POCT) patient-friendly assay in a compact format for the early diagnosis of Alzheimer''s disease (AD). For conducting the assay, we used human sera of 40 subjects divided into halves, which were grouped into AD patients and control groups according to a number of neuropsychological tests. We found that on an average, the concentrations of both total tau and phosphorylated tau proteins (all known to be higher in cerebrospinal fluid (CSF) and the brain) turned out to be higher in human sera of AD patients than in controls. The limits of detection of total tau and phosphorylated tau proteins were 2.4 pg mL⁻¹ and 1.6 pg mL⁻¹, respectively. In particular, it was found that the AD group exhibited average concentration of total tau proteins 6-fold higher than the control group, while concentration of phosphorylated tau proteins was 3-fold higher than that of the control. We can attribute this inhomogeneity between both types of tau proteins (in terms of increase of control-to-AD in average concentration) to un-phosphorylated tau proteins being more likely to be produced in blood than phosphorylated tau proteins, which possibly is one of the potential key elements playing an important role in AD progress.

Sun protective behaviors at an outdoor entertainment event in Australia

An observational study was conducted to examine the use of sun protective hats, clothing, and sunglasses of people attending an outdoor entertainment event in an area of high‐to‐extreme ultraviolet radiation in New South Wales, Australia. Armidale is unique, as it is a highly‐elevated area, almost 1000 m above sea level, and temperatures are often mild with very high‐to‐extreme levels of ultraviolet radiation. Four trained data collectors observed attendees as they entered the event, and recorded their use of sun protective hats, clothing, and sunglasses. While more than half of the attendees wore sun protective hats, only 14% wore sun protective clothing. Broad‐brimmed hats were considered sun protective, while sun protective clothing was defined by shirts with at least three‐quarter‐length sleeves. Females were more likely to wear both a sun protective hat and clothing than males, and children were less protected than adults. Legislative changes are required to ensure that organizers of outdoor events have a legal responsibility to provide a safe environment for attendees, including strategies to help reduce ultraviolet radiation exposure.     

General hospital health professionals’ attitudes and perceived dangerousness towards patients with comorbid mental and physical health conditions: Systematic review and meta‐analysis

The stigmatization of mental health is present in general hospital settings impacting quality of care. We hypothesized that health professionals in these areas would elicit negative attitudes and a perceived level of dangerousness across a range of mental health disorders. We aimed to conduct a systematic review and meta‐analysis to examine these attitudes and perceptions. We searched the bibliographic databases of CINAHL Complete, MEDLINE Complete, PsycINFO, and Psychology and Behavioral Sciences Collection in May 2017 (no date parameters were set). Quantitative studies investigating generalist health professionals’ attitudes towards mental health conditions were selected. Initially, prevalence meta‐analyses were conducted to assess the extent of perceived danger, followed by a series of comparative meta‐analyses in which the perceived dangerousness of mental health conditions was compared. Of the 653 citations retrieved, eight studies met the inclusion criteria. The overall sample included 2548 health professionals. A majority of health professionals perceived patients with substance use disorder as dangerous 0.60 (95% CI: 0.32–0.88) when compared with patients who had an alcohol‐related disorder, schizophrenia, and depression. The results also indicated that a large proportion of staff perceived patients with a diagnosis of schizophrenia as dangerous 0.42 (95% CI: 0.33–0.52). Negative attitudes towards people experiencing mental illness in general hospital settings may be attributed to poor mental health literacy, skills and limited exposure, and social and cultural beliefs about mental illness. Ongoing professional development targeting mental health knowledge is recommended for health professionals working in general hospital settings.
