Social Determinants of Health Framework to Identify and Reduce Barriers to Imaging in Marginalized Communities.

Social determinants of health (SDOH) are conditions influencing individuals' health based on their environment of birth, living, working, and aging. Addressing SDOH is crucial for promoting health equity and reducing health outcome disparities. For conditions such as stroke and cancer screening where imaging is central to diagnosis and management, access to high-quality medical imaging is necessary. This article applies a previously described structural framework characterizing the impact of SDOH on patients who require imaging for their clinical indications. SDOH factors can be broadly categorized into five sectors: economic stability, education access and quality, neighborhood and built environment, social and community context, and health care access and quality. As patients navigate the health care system, they experience barriers at each step, which are significantly influenced by SDOH factors. Marginalized communities are prone to disparities due to the inability to complete the required diagnostic or screening imaging work-up. This article highlights SDOH that disproportionately affect marginalized communities, using stroke and cancer as examples of disease processes where imaging is needed for care. Potential strategies to mitigate these disparities include dedicating resources for clinical care coordinators, transportation, language assistance, and financial hardship subsidies. Last, various national and international health initiatives are tackling SDOH and fostering health equity.

Standardized reporting for Head CT Scans in patients suspected of traumatic brain injury (TBI): An international expert endeavor.

BACKGROUND AND PURPOSE: Traumatic brain injury (TBI) is a major source of health loss and disability worldwide. Accurate and timely diagnosis of TBI is critical for appropriate treatment and management of the condition. Neuroimaging plays a crucial role in the diagnosis and characterization of TBI. Computed tomography (CT) is the first-line diagnostic imaging modality typically utilized in patients with suspected acute mild, moderate and severe TBI. Radiology reports play a crucial role in the diagnostic process, providing critical information about the location and extent of brain injury, as well as factors that could prevent secondary injury. However, the complexity and variability of radiology reports can make it challenging for healthcare providers to extract the necessary information for diagnosis and treatment planning. METHODS/RESULTS/CONCLUSION: In this article, we report the efforts of an international group of TBI imaging experts to develop a clinical radiology report template for CT scans obtained in patients suspected of TBI and consisting of fourteen different subdivisions (CT technique, mechanism of injury or clinical history, presence of scalp injuries, fractures, potential vascular injuries, potential injuries involving the extra-axial spaces, brain parenchymal injuries, potential injuries involving the cerebrospinal fluid spaces and the ventricular system, mass effect, secondary injuries, prior or coexisting pathology).

Imaging Artificial Intelligence: A Framework for Radiologists to Address Health Equity, From the AJR Special Series on DEI.

Artificial intelligence (AI) holds promise for helping patients access new and individualized health care pathways while increasing efficiencies for health care practitioners. Radiology has been at the forefront of this technology in medicine; many radiology practices are implementing and trialing AI-focused products. AI also holds great promise for reducing health disparities and promoting health equity. Radiology is ideally positioned to help reduce disparities given its central and critical role in patient care. The purposes of this article are to discuss the potential benefits and pitfalls of deploying AI algorithms in radiology, specifically highlighting the impact of AI on health equity; to explore ways to mitigate drivers of inequity; and to enhance pathways for creating better health care for all individuals, centering on a practical framework that helps radiologists address health equity during deployment of new tools.

Natural history of abdominal pain in family practice: Longitudinal study of electronic medical record data in southwestern Ontario.

OBJECTIVE: To examine the frequency, natural history, and outcomes of 3 subtypes of abdominal pain (general abdominal pain, epigastric pain, localized abdominal pain) among patients visiting Canadian family practices. DESIGN: Retrospective cohort study with a 4-year longitudinal analysis. SETTING: Southwestern Ontario. PARTICIPANTS: A total of 1790 eligible patients with International Classification of Primary Care codes for abdominal pain from 18 family physicians in 8 group practices. MAIN OUTCOME MEASURES: The symptom pathways, the length of an episode, and the number of visits. RESULTS: Abdominal pain accounted for 2.4% of the 15,149 patient visits and involved 14.0% of the 1790 eligible patients. The frequencies of each of the 3 subtypes were as follows: localized abdominal pain, 89 patients, 1.0% of visits, and 5.0% of patients; general abdominal pain, 79 patients, 0.8% of visits, and 4.4% of patients; and epigastric pain, 65 patients, 0.7% of visits, and 3.6% of patients. Those with epigastric pain received more medications, and patients with localized abdominal pain underwent more investigations. Three longitudinal outcome pathways were identified. Pathway 1, in which the symptom remains at the end of the visit with no diagnosis, was the most common among patients with all subtypes of abdominal symptoms at 52.8%, 54.4%, and 50.8% for localized, general, and epigastric pain, respectively, and the symptom episodes were relatively short. Less than 15% of patients followed pathway 2, in which a diagnosis is made and the symptom persists, and yet the episodes were long with 8.75 to 16.80 months' mean duration and 2.70 to 4.00 mean number of visits. Pathway 3, in which a diagnosis is made and there are no further visits for that symptom, occurred approximately one-third of the time, with about 1 visit over about 2 months. Prior chronic conditions were common across all 3 subtypes of abdominal pain ranging from 72.2% to 80.0%. Psychological symptoms consistently occurred at a rate of approximately one-third. CONCLUSION: The 3 subtypes of abdominal pain differed in clinically important ways. The most frequent pathway was that the symptom remained with no diagnosis, suggesting a need for clinical approaches and education programs for care of symptoms themselves, not merely in the service of coming to a diagnosis. The importance of prior chronic conditions and psychological conditions was highlighted by the results.

Surviving families of military suicide loss: Exploring postvention peer support.

The United States military began to experience a steady increase in suicide rates across all service branches at the inception of the wars in Afghanistan (2001) and Iraq (2003). As the number of suicide deaths increased, so did the number of affected survivors who seek postvention support. Unique issues that accompany suicide death may expose survivors to a more distressing and complicated grief process. Peer support has clinically been observed to be widely utilized by suicide loss survivors. This article explores unique issues accompanying military suicide loss, potential benefits of postvention peer-based support, clinical considerations, and future directions.

Development of a decision-making tool for reporting drivers with mild dementia and mild cognitive impairment to transportation administrators.

BACKGROUND: Driving in persons with dementia poses risks that must be counterbalanced with the importance of the care for autonomy and mobility. Physicians often find substantial challenges in the assessment and reporting of driving safety for persons with dementia. This paper describes a driving in dementia decision tool (DD-DT) developed to aid physicians in deciding when to report older drivers with either mild dementia or mild cognitive impairment to local transportation administrators. METHODS: A multi-faceted, computerized decision support tool was developed, using a systematic literature and guideline review, expert opinion from an earlier Delphi study, as well as qualitative interviews and focus groups with physicians, caregivers of former drivers with dementia, and transportation administrators. The tool integrates inputs from the physician-user about the patient's clinical and driving history as well as cognitive findings, and it produces a recommendation for reporting to transportation administrators. This recommendation is translated into a customized reporting form for the transportation authority, if applicable, and additional resources are provided for the patient and caregiver. CONCLUSIONS: An innovative approach was needed to develop the DD-DT. The literature and guideline review confirmed the algorithm derived from the earlier Delphi study, and barriers identified in the qualitative research were incorporated into the design of the tool.

Introduction.

This article provides an introduction to this special issue of Death Studies on suicide postvention. The articles in the issue are derived from a document released by the National Action Alliance for Suicide Prevention, titled Responding to Grief, Trauma, and Distress after Suicide: U.S. National Guidelines. The article provides data and a rationale for considering suicide as a serious public health issue in the USA and around the world, and the need for postvention after a suicide occurs. A brief description of each of the articles in the special issue then follows.

Postvention is prevention-The case for suicide postvention.

There is now convincing empirical evidence that exposure to suicide increases the risk of subsequent suicide, as well as other negative mental health sequelae, in those who have been exposed. This article provides a review of this empirical evidence. It also concludes that this substantial evidence base makes the compelling case that all suicide prevention programs need to include postvention services as a direct form of suicide prevention with a population of people known to be at heightened risk for suicide themselves: suicide loss survivors.

Clinical work with suicide loss survivors: Implications of the U.S. postvention guidelines.

The loss of a loved one to suicide can present difficult challenges for suicide loss survivors (people bereaved by suicide) as well as for clinicians who would seek to help them. Building on the recommendations in the new document Responding to Grief, Trauma, and Distress after a Suicide: U.S. National Guidelines, this article provides an overview of clinical work with suicide loss survivors. It includes discussions of the common themes of suicide bereavement, the psychological tasks for integration of a suicide loss, and the options for providing grief therapy after a suicide. The article will be of value to caregivers who work with suicide loss survivors in counseling or therapeutic context.

The Perceived Experience of Children Bereaved by Parental Suicide.

Children whose parent died by suicide are a vulnerable and underserved population. This phenomenon will be described, as well as implications for practice and research. "Double Whammy," a conceptualization of the overall experience of this marginalized group, emerged through two in-depth interviews from a phenomenological qualitative study with professionals who facilitate support groups for children bereaved by parental suicide. It was corroborated with current literature and practice experiences of the authors and their colleagues. Stigma was the largest contributor to the "Double Whammy," and the following themes emerged as well: feeling isolated, feeling abandoned, and feeling responsible. The self-volition of suicide challenges how bereaved children make meaning and internalize feelings about the deceased parent, one's self, and others. Developmentally appropriate education about suicide grief, depression, and normalizing the grief process is pivotal in helping children to effectively cope and manage their feelings.

On the Analytical Superiority of 1D NMR for Fingerprinting the Higher Order Structure of Protein Therapeutics Compared to Multidimensional NMR Methods.

An important aspect in the analytical characterization of protein therapeutics is the comprehensive characterization of higher order structure (HOS). Nuclear magnetic resonance (NMR) is arguably the most sensitive method for fingerprinting HOS of a protein in solution. Traditionally, (1)H-(15)N or (1)H-(13)C correlation spectra are used as a "structural fingerprint" of HOS. Here, we demonstrate that protein fingerprint by line shape enhancement (PROFILE), a 1D (1)H NMR spectroscopy fingerprinting approach, is superior to traditional two-dimensional methods using monoclonal antibody samples and a heavily glycosylated protein therapeutic (Epoetin Alfa). PROFILE generates a high resolution structural fingerprint of a therapeutic protein in a fraction of the time required for a 2D NMR experiment. The cross-correlation analysis of PROFILE spectra allows one to distinguish contributions from HOS vs protein heterogeneity, which is difficult to accomplish by 2D NMR. We demonstrate that the major analytical limitation of two-dimensional methods is poor selectivity, which renders these approaches problematic for the purpose of fingerprinting large biological macromolecules.

Pneumonia Associated with an Influenza A H3 Outbreak at a Skilled Nursing Facility--Florida, 2014.

In December 2014, the Florida Department of Health, Bureau of Epidemiology, was notified that 18 of 95 (19%) residents at a skilled nursing facility had radiographic evidence of pneumonia and were being treated with antibiotics. Two residents were hospitalized, one of whom died. A second resident died at the facility. The Florida Department of Health conducted an outbreak investigation to ascertain all cases through active case finding, identify the etiology, provide infection control guidance, and recommend treatment or prophylaxis, if indicated.

Broadly protective protein-based pneumococcal vaccine composed of pneumolysin toxoid-CbpA peptide recombinant fusion protein.

BACKGROUND: Pneumococcus, meningococcus, and Haemophilus influenzae cause a similar spectrum of infections in the ear, lung, blood, and brain. They share cross-reactive antigens that bind to the laminin receptor of the blood-brain barrier as a molecular basis for neurotropism, and this step in pathogenesis was addressed in vaccine design. METHODS: Biologically active peptides derived from choline-binding protein A (CbpA) of pneumococcus were identified and then genetically fused to L460D pneumolysoid. The fusion construct was tested for vaccine efficacy in mouse models of nasopharyngeal carriage, otitis media, pneumonia, sepsis, and meningitis. RESULTS: The CbpA peptide-L460D pneumolysoid fusion protein was more broadly immunogenic than pneumolysoid alone, and antibodies were active in vitro against Streptococcus pneumoniae, Neisseria meningitidis, and H. influenzae. Passive and active immunization protected mice from pneumococcal carriage, otitis media, pneumonia, bacteremia, meningitis, and meningococcal sepsis. CONCLUSIONS: The CbpA peptide-L460D pneumolysoid fusion protein was broadly protective against pneumococcal infection, with the potential for additional protection against other meningeal pathogens.

Teaching primary care obstetrics: insights and recruitment recommendations from family physicians.

OBJECTIVE: To explore the experiences and recommendations for recruitment of family physicians who practise and teach primary care obstetrics. DESIGN: Qualitative study using in-depth interviews. SETTING: Six primary care obstetrics groups in Edmonton, Alta, that were involved in teaching family medicine residents in the Department of Family Medicine at the University of Alberta. PARTICIPANTS: Twelve family physicians who practised obstetrics in groups. All participants were women, which was reasonably representative of primary care obstetrics providers in Edmonton. METHODS: Each participant underwent an in-depth interview. The interviews were audiotaped and transcribed verbatim. The investigators independently reviewed the transcripts and then analyzed the transcripts together in an iterative and interpretive manner. MAIN FINDINGS: Themes identified in this study include lack of confidence in teaching, challenges of having learners, benefits of having learners, and recommendations for recruiting learners to primary care obstetrics. While participants described insecurity and challenges related to teaching, they also identified positive aspects, and offered suggestions for recruiting learners to primary care obstetrics. CONCLUSION: Despite describing poor confidence as teachers and having challenges with learners, the participants identified positive experiences that sustained their interest in teaching. Supporting these teachers and recruiting more such role models is important to encourage family medicine learners to enter careers such as primary care obstetrics.

Understanding Bias in Artificial Intelligence: A Practice Perspective.

In the fall of 2021, several experts in this space delivered a Webinar hosted by the American Society of Neuroradiology (ASNR) Diversity and Inclusion Committee, focused on expanding the understanding of bias in artificial intelligence, with a health equity lens, and provided key concepts for neuroradiologists to approach the evaluation of these tools. In this perspective, we distill key parts of this discussion, including understanding why this topic is important to neuroradiologists and lending insight on how neuroradiologists can develop a framework to assess health equity-related bias in artificial intelligence tools. In addition, we provide examples of clinical workflow implementation of these tools so that we can begin to see how artificial intelligence tools will impact discourse on equitable radiologic care. As continuous learners, we must be engaged in new and rapidly evolving technologies that emerge in our field. The Diversity and Inclusion Committee of the ASNR has addressed this subject matter through its programming content revolving around health equity in neuroradiologic advances.

Intersectionality and Faculty Compensation in Academic Radiology in U.S.

BACKGROUND: The impact of intersectionality on academic radiology physician compensation is not well known. PURPOSE: The aim of this study was to assess impact of intersectionality on academic radiology financial compensation, based on rank, gender and race/ethnicity in US medical schools. METHODS: Data were collected from the AAMC Faculty Salary Survey, which collects information for full-time faculty at U.S. medical schools. Financial compensation data for radiology faculty with MD or equivalent degree in diagnostic radiology (DR) as well as interventional radiology (IR) was collected for 2023, stratified by rank, gender, and race/ethnicity. RESULTS: The AAMC Faculty Salary Survey data for 2023 included responses for 683 IR (138 women, 545 men) and 2431 DR (862 women, 1569 men) faculty. Men had a higher median compensation than women at all ranks, for both IR and DR, except DR instructors. The gender pay gap was greater in IR faculty compared to DR faculty of the same rank. All intersectional groups among IR faculty reported a lower median compensation compared to White men of the same rank. All intersectional groups among DR faculty, except Asian Men, had a lower median compensation than White men of the same rank. Among IR faculty, Asian women assistant professors faced the greatest disparity in median compensation, down to $75 K (15%) lower than White men. Among DR faculty, Black/African American women assistant professors faced the greatest disparity on median compensation, down to $48 K (10.5%) lower than White men. CONCLUSION: The study results raise important concerns about impact of intersectionality on faculty compensation in radiology which needs further study and should be addressed as part of broader drive to increase diversity, equity, and inclusion in academic radiology.

Low COVID-19 vaccine uptake in people living with HIV and those with hypertension and diabetes without HIV at Mbarara and Masaka regional referral hospitals: A cross-sectional survey.

Chronic diseases such as HIV, hypertension, and diabetes increase the risk of severe coronavirus disease 2019 (COVID-19) and death. Thus, COVID-19 vaccine uptake data among these priority populations are needed to inform immunization programs. We assessed COVID-19 vaccine uptake among people living with HIV (PLWH) and those with hypertension/diabetes without HIV (PWoH) in Southwestern and Southcentral Uganda and determined factors influencing vaccination. We conducted a cross-sectional study from January to April 2023. We enrolled a random sample of participants aged 18 years and older seeking HIV, hypertension, or diabetes care at two regional referral hospitals (RRHs) in Mbarara and Masaka in Uganda. Using vaccination records abstraction and interviewer-administered questionnaires, we collected data on COVID-19 vaccine uptake, sociodemographic data, and reasons for non-uptake in unvaccinated persons. We compared COVID-19 vaccination uptake between PLWH and PWoH and applied modified Poisson regression to determine sociodemographic factors associated with vaccine uptake. The reasons for non-vaccine uptake were presented as percentages. Of the 1,376 enrolled participants, 65.6% were fully vaccinated against COVID-19. Vaccination coverage was 65% among PWLH versus 67% among PWoH. Higher education attainment and older age were associated with COVID vaccination. Participants with secondary education and those aged ≥50 years achieved >70% coverage. Fear of side effects was the most cited reason (67%) for non-vaccination among 330 unvaccinated participants, followed by vaccine mistrust (24.5%). People with chronic diseases in Southwestern Uganda had slightly lower than 70% COVID-19 vaccine coverage as recommended by WHO. Higher educational attainment and older age were linked to increased vaccine uptake. However, mistrust and fear of vaccine side effects were the main reasons for non-vaccination. To increase COVID-19 vaccine uptake, programs must reach those with lower educational attainment and younger age groups, and address the fear of vaccine side effects and mistrust among persons with underlying diseases in Uganda.

Monthly Sulfadoxine-Pyrimethamine During Pregnancy Prevents Febrile Respiratory Illnesses: A Secondary Analysis of a Malaria Chemoprevention Trial in Uganda.

Background: Trials evaluating antimalarials for intermittent preventive treatment in pregnancy (IPTp) have shown that dihydroartemisinin-piperaquine (DP) is a more efficacious antimalarial than sulfadoxine-pyrimethamine (SP); however, SP is associated with higher birthweight, suggesting that SP demonstrates "nonmalarial" effects. Chemoprevention of nonmalarial febrile illnesses (NMFIs) was explored as a possible mechanism. Methods: In this secondary analysis, we leveraged data from 654 pregnant Ugandan women without HIV infection who participated in a randomized controlled trial comparing monthly IPTp-SP with IPTp-DP. Women were enrolled between 12 and 20 gestational weeks and followed through delivery. NMFIs were measured by active and passive surveillance and defined by the absence of malaria parasitemia. We quantified associations among IPTp regimens, incident NMFIs, antibiotic prescriptions, and birthweight. Results: Mean "birthweight for gestational age" Z scores were 0.189 points (95% CI, .045-.333) higher in women randomized to IPTp-SP vs IPTp-DP. Women randomized to IPTp-SP had fewer incident NMFIs (incidence rate ratio, 0.74; 95% CI, .58-.95), mainly respiratory NMFIs (incidence rate ratio, 0.69; 95% CI, .48-1.00), vs IPTp-DP. Counterintuitively, respiratory NMFI incidence was positively correlated with birthweight in multigravidae. In total 75% of respiratory NMFIs were treated with antibiotics. Although overall antibiotic prescriptions were similar between arms, for each antibiotic prescribed, "birthweight for gestational age" Z scores increased by 0.038 points (95% CI, .001-.074). Conclusions: Monthly IPTp-SP was associated with reduced respiratory NMFI incidence, revealing a potential nonmalarial mechanism of SP and supporting current World Health Organization recommendations for IPTp-SP, even in areas with high-grade SP resistance. While maternal respiratory NMFIs are known risk factors of lower birthweight, most women in our study were presumptively treated with antibiotics, masking the potential benefit of SP on birthweight mediated through preventing respiratory NMFIs.

Profiling formulated monoclonal antibodies by (1)H NMR spectroscopy.

Nuclear magnetic resonance (NMR) is arguably the most direct methodology for characterizing the higher-order structure of proteins in solution. Structural characterization of proteins by NMR typically utilizes heteronuclear experiments. However, for formulated monoclonal antibody (mAb) therapeutics, the use of these approaches is not currently tenable due to the requirements of isotope labeling, the large size of the proteins, and the restraints imposed by various formulations. Here, we present a new strategy to characterize formulated mAbs using (1)H NMR. This method, based on the pulsed field gradient stimulated echo (PGSTE) experiment, facilitates the use of (1)H NMR to generate highly resolved spectra of intact mAbs in their formulation buffers. This method of data acquisition, along with postacquisition signal processing, allows the generation of structural and hydrodynamic profiles of antibodies. We demonstrate how variation of the PGSTE pulse sequence parameters allows proton relaxation rates and relative diffusion coefficients to be obtained in a simple fashion. This new methodology can be used as a robust way to compare and characterize mAb therapeutics.

Randomized trial of distance-based treatment for young children with discipline problems seen in primary health care.

OBJECTIVE: Many parents of preschool-age children have concerns about how to discipline their child but few receive help. We examined the effects of a brief treatment along with usual care, compared with receiving usual care alone. Patients. Parents (N = 178) with concerns about their 2- to 5-year olds' discipline were recruited when they visited their family physician at 1 of 24 practices. METHODS: After completing mailed baseline measures, parents were randomly assigned to receive usual care or the Parenting Matters intervention along with usual care. Parenting Matters combined a self-help booklet with two calls from a telephone coach during a 6-week treatment period. Follow-up assessments were completed at 7 weeks post-randomization, and 3 and 6 months later. RESULTS: Behaviour problems (Eyberg Child Behaviour Inventory) decreased significantly more in the Parenting Matters condition compared with Usual Care alone, based on a significant time by treatment group effect in intent-to-treat, growth curve analyses (P = 0.033). The Parenting Matters group also demonstrated greater and more rapid improvement than in usual care alone in terms of overall psychopathology (Child Behaviour Checklist, P = 0.02), but there were no group differences in parenting. The overall magnitude of group differences was small (d = 0.15 or less). CONCLUSION: A brief early intervention combining a self-help booklet and telephone coaching is an effective way to treat mild behaviour problems among young children. This minimal-contact approach addresses the need for interventions in primary health care settings and may be a useful component in step-care models of mental health.
