Acceptability and feasibility of screening with a pediatric care provider-led social determinants of health identification tool.

BACKGROUND: Complex social determinants of health may not be easily recognized by health care providers and pose a unique challenge in the vulnerable pediatric population where patients may not be able to advocate for themselves. The goal of this study was to examine the acceptability and feasibility of health care providers using an integrated brief pediatric screening tool in primary care and hospital settings. METHODS: The framework of the Child and Adolescent Needs and Strengths (CANS) and Pediatric Intermed tools was used to inform the selection of items for the 9-item Child and Adolescent Needs and Strengths-Pediatric Complexity Indicator (CANS-PCI). The tool consisted of three domains: biological, psychological, and social. Semi-structured interviews were conducted with health care providers in pediatric medical facilities in Ottawa, Canada. A low inference and iterative thematic synthesis approach was used to analyze the qualitative interview data specific to acceptability and feasibility. RESULTS: Thirteen health care providers participated in interviews. Six overarching themes were identified: acceptability, logistics, feasibility, pros/cons, risk, and privacy. Overall, participants agreed that a routine, trained provider-led pediatric tool for the screening of social determinants of health is important (n = 10, 76.9%), acceptable (n = 11; 84.6%), and feasible (n = 7, 53.8%). INTERPRETATION: Though the importance of social determinants of health are widely recognized, there are limited systematic methods of assessing, describing, and communicating amongst health care providers about the biomedical and psychosocial complexities of pediatric patients. Based on this study's findings, implementation of a brief provider-led screening tool into pediatric care practices may contribute to this gap.

Point-of-Care Synchronous Virtual Radiology Consultations for Atherosclerotic Disease in Primary Care: A Cluster-Randomized Study.

PURPOSE: Synchronous virtual visits are an emerging model of care, and their feasibility has been demonstrated in radiology. The purpose of this study was to assess the value of point-of-care virtual radiology primary care consultations for atherosclerotic vascular disease management. METHODS: In this institutional review board-approved study, 107 age- and gender-matched patients were assigned to control (n = 62) and intervention (n = 45) arms with the following inclusion criteria: (1) age > 45 years, (2) consult with a primary care physician (PCP), and (3) recent CT of the chest or abdomen demonstrating atherosclerotic calcification. In the intervention arm, virtual real-time radiology consultation with referring PCPs and patients was conducted, with review of CT images focused on the extent of vascular atherosclerosis. Patients in the control arm followed the current standard of care of PCPs' discussing relevant imaging results, if any. RESULTS: Thirty-one patients in the intervention arm and 31 patients in the control arm completed the study (control: 64.5% women; mean age, 68 years; intervention: 67.7% women; mean age, 67 years). Discussion of imaging findings occurred with all patients in the intervention arm (discussion with PCP and virtual consultation with radiologist) and with 45% of patients in the control arm (PCP only; P < .001). All patients in the intervention arm indicated that seeing or discussing their images improved their understanding of their disease, compared with 85% of patients in the control arm (P = .04). In the intervention arm, 10 of 31 patients (32.2%) left the visit with changes in prescriptions for statins or antihypertensive medications, compared with only 4 of 31 patients (13%) in the control arm (P = .04). CONCLUSIONS: Point-of-care radiology virtual visits enhance patient understanding and may influence the longitudinal management of atherosclerotic disease in primary care.

Religiously Diverse Multicultural Literature for Early Childhood.

Through culturally sustaining teaching, teachers can transform practice and pedagogy to challenge inequities and create a space for affirming students' diverse religious backgrounds. Teacher educators and teachers must develop this pedagogy to understand diverse student populations and facilitate students becoming citizens who accept and empathize with others who have different religious beliefs and traditions. Our purpose was to explore and select multicultural literature that represents religious diversity for early childhood classrooms. Our search focused on major religions practiced in the U.S., which yielded 549 books. We obtained 436 books; 54 met the rubric criteria with a majority focusing on Judaism. We identified four themes: immigration and refugees, holidays, sharing memories and stories, building understandings and empathy. We offered examples of the themes and an example of implementation in the classroom. We recommended this sample that we believe can foster understanding and respect for diverse religious and cultural groups.

Exposing cryptic epitopes on the Venezuelan equine encephalitis virus E1 glycoprotein prior to treatment with alphavirus cross-reactive monoclonal antibody allows blockage of replication early in infection.

Eastern equine encephalitis virus (EEEV), western equine encephalitis virus (WEEV) and Venezuelan equine encephalitis virus (VEEV) can cause fatal encephalitis in humans and equids. Some MAbs to the E1 glycoprotein are known to be cross-reactive, weakly neutralizing in vitro but can protect from disease in animal models. We investigated the mechanism of neutralization of VEEV infection by the broadly cross-reactive E1-specific MAb 1A4B-6. 1A4B-6 protected 3-week-old Swiss Webster mice prophylactically from lethal VEEV challenge. Likewise, 1A4B-6 inhibited virus growth in vitro at a pre-attachment step after virions were incubated at 37 °C and inhibited virus-mediated cell fusion. Amino acid residue N100 in the fusion loop of E1 protein was identified as critical for binding. The potential to elicit broadly cross-reactive MAbs with limited virus neutralizing activity in vitro but that can inhibit virus entry and protect animals from infection merits further exploration for vaccine and therapeutic developmental research.

Three-Day Dietary Manipulation in Multiple Sclerosis: Exercise and Fatigue Outcomes.

BACKGROUND: In persons with multiple sclerosis (MS), the effect of nutrition on exercise performance and fatigue remains unknown. The objective was to determine whether a 3-day diet high in triglycerides (FAT) compared with a 3-day diet high in carbohydrates (CARB) would improve fatigue and exercise performance in persons with MS. METHODS: A randomized controlled crossover design was incorporated to study FAT versus CARB on submaximal cycling endurance (60% of peak oxygen consumption), substrate utilization, and fatigue in 12 persons with mild-to-moderate MS (Expanded Disability Status Scale score, 2.0-5.0) and 12 age- and sex-matched controls. RESULTS: There were no differences in cycling time between diets in either group (P = .29). The MS group had no changes in fatigue between diets (P = .64); the control group demonstrated increased total mental fatigue after FAT (P = .05). The control group increased carbohydrate oxidation by 24% at rest and 13% during exercise after CARB. Similarly, the control group significantly increased fat oxidation after FAT by 22% at rest and 68% during exercise (P = .01). These changes were not seen in the MS group. Compared with controls, persons with MS oxidized approximately 50% less fat during exercise after FAT (P = .05). CONCLUSIONS: Neither CARB nor FAT altered submaximal exercise performance or baseline fatigue in the MS group. The results suggest that persons with MS are unable to adapt to dietary changes and oxidize fatty acids as efficiently as controls.

Access to Multicultural Children's Literature During COVID-19.

Amid the COVID-19 pandemic, students, families, and educators have faced unprecedented challenges. These challenges have disproportionately impacted racially/ethnically diverse, low-income communities because of long-standing health system, socioeconomic, and educational inequities. With closures of schools, libraries, and childcare centers, many students were disconnected from their community and did not have access to books. Parents' and educators' concerns centered around students falling behind academically and socially. In this article, we explain the motivation and rationale for a social justice initiative to provide students of color from low-poverty areas with access to high-quality multicultural children's literature at home. We describe our literacy partnership with a local after-school program serving participant students and families, research underpinning the initiative, and our process for selecting high-quality multicultural literature book sets and offer suggestions about how to facilitate comprehension and motivational support for home-based reading. We also offer a list of recommended literature and discuss outcomes and implications of this project.

Point-of-Care Virtual Radiology Consultations in Primary Care: A Feasibility Study of a New Model for Patient-Centered Care in Radiology.

BACKGROUND: The goal of this study is to assess the value of point-of-care virtual consultations in radiology. METHODS: We conducted an institutional review board-approved feasibility study of video-based radiology consultations in an internal medicine primary care clinic at a quaternary academic medical center. The study included 3 primary care providers (PCPs) and enrolled 43 patients. Inclusion criteria consisted of the following: age > 18 years, English speaking, recent radiology examination at our institution, and patient consenting to participate. Patients completed a pre- and postvisit survey. PCPs completed a postvisit survey. Primary study end points included the effect on patient and provider satisfaction, effect on patient experience and understanding of medical condition, and impact on PCP's management decisions. Statistical significance was assessed using Fisher's exact test. RESULTS: Of the enrolled patients, 93% (n = 40 of 43) indicated that they were satisfied with the virtual consultation visit. The PCPs were satisfied with the virtual consultation in 97% of consultations (n = 42 of 43). In addition, 88% (n = 38 of 43) of patients indicated improved understanding of their medical condition as a result of the virtual consultation, and 91% of patients (n = 39 of 43) were interested in similar consultations in the future. The participating PCPs indicated that the consultation was helpful in their management decisions in 83% of visits. Patient's interest in receiving their imaging results from radiologist increased from 56% to 88% when comparing pre- and post-virtual consultation survey results (P = .03). CONCLUSION: Initial experience with virtual radiology consultations show high rates of patient and provider satisfaction. Virtual radiology consultations have the potential to advance radiology's value in care delivery.

The Emerging Global Tobacco Treatment Workforce: Characteristics of Tobacco Treatment Specialists Trained in Council-Accredited Training Programs from 2017 to 2019.

Tobacco use is projected to kill 1 billion people in the 21st century. Tobacco Use Disorder (TUD) is one of the most common substance use disorders in the world. Evidence-based treatment of TUD is effective, but treatment accessibility remains very low. A dearth of specially trained clinicians is a significant barrier to treatment accessibility, even within systems of care that implement brief intervention models. The treatment of TUD is becoming more complex and tailoring treatment to address new and traditional tobacco products is needed. The Council for Tobacco Treatment Training Programs (Council) is the accrediting body for Tobacco Treatment Specialist (TTS) training programs. Between 2016 and 2019, n = 7761 trainees completed Council-accredited TTS training programs. Trainees were primarily from North America (92.6%) and the Eastern Mediterranean (6.1%) and were trained via in-person group workshops in medical and academic settings. From 2016 to 2019, the number of Council-accredited training programs increased from 14 to 22 and annual number of trainees increased by 28.5%. Trainees have diverse professional backgrounds and work in diverse settings but were primarily White (69.1%) and female (78.7%) located in North America. Nearly two-thirds intended to implement tobacco treatment services in their setting; two-thirds had been providing tobacco treatment for 1 year or less; and 20% were sent to training by their employers. These findings suggest that the training programs are contributing to the development of a new workforce of TTSs as well as the development of new programmatic tobacco treatment services in diverse settings. Developing strategies to support attendance from demographically and geographically diverse professionals might increase the proportion of trainees from marginalized groups and regions of the world with significant tobacco-related inequities.

Computed tomography findings of metabolic syndrome in patients with acute colonic diverticulitis.

INTRODUCTION: Many factors associated with colonic diverticulitis are also part of the clinical definition of the metabolic syndrome. Computed tomography (CT) is commonly performed in symptomatic patients, such as those with suspected or known acute diverticulitis, and could add additional value for the health of these patients by identifying and reporting CT biomarkers of metabolic syndrome, if present and detectable. The purpose of this study was to identify CT biomarkers of metabolic syndrome in patients with acute colonic diverticulitis. METHODS: We retrospectively reviewed 243 patients (mean-60 yrs, M:F:126:117) diagnosed with colonic diverticulitis on CT between March 2015 and March 2017 for hepatic steatosis, vascular calcifications, abdominal diameters and fat volumes. Criteria of metabolic syndrome were obtained from medical records. Differences in imaging biomarkers were compared using chi-square comparisons stratified by metabolic syndrome, abdominal diameter and fat volume. RESULTS: Of 243 patients, 33% demonstrated hepatic steatosis and 71% atherosclerotic vascular calcifications on CT. 28% met criteria for metabolic syndrome. Patients with metabolic syndrome had higher occurrence of hepatic steatosis, sagittal diameter ≥ 35 cm, visceral fat > 5000 cm3 and subcutaneous fat > 8300 cm3 (P < 0.05), but not vascular calcifications (P > 0.05). CONCLUSIONS: CT biomarkers of metabolic syndrome are commonly encountered in patients with acute diverticulitis. Recognizing and reporting these findings can guide towards further evaluation for metabolic syndrome.

More than Just Soup: Use of a Student-Led COVID-19 Social Pediatrics Initiative to Propose the Integration of Social Medicine Electives in Undergraduate Medical Education.

INTRODUCTION: The need to educate medical students on the social forces shaping disease and health patterns is paramount in preparing incoming physicians with the aptitudes to address health inequities. Despite its well-documented merit as a model of practice, social medicine remains underrepresented at the undergraduate medical education level. We hypothesize that the success of this student-led COVID-19 initiative proposes a tangible and innovative solution to address the lack of social medicine exposure in undergraduate medical education. METHODOLOGY: We sought to evaluate the impact of sustaining clinical learning during the pandemic using the social pediatrics model as a didactic vector for clerkship students. We extracted learning objectives relevant to the teaching of social medicine from the Royal College of Physicians and Surgeons of Canada's CanMEDS framework and developed a survey aimed at evaluating the attainability of each of those objectives. The survey was distributed to students enrolled in the social pediatrics COVID-19 initiative after 6 weeks (April-May), as well as a control group. RESULTS: Completing the survey were 19 students from the University of Ottawa Faculty of Medicine, 7 in the intervention group and 12 in the control group. Students that participated in the social pediatrics initiative yielded significantly higher values for the achievement of 6 out of 9 social medicine learning objectives when compared to the control group. Although the values followed a similar trend for the remaining 3 objectives, favoring the intervention group, they were not statistically significant. CONCLUSION: The positive results from this study and the COVID-19 student-led initiative template can serve as a catalyst for curricular change so as to ensure graduates are adequately trained to contend with the realities of the social landscape in which they will practice. Future plans include the incorporation of interactive social medicine experiences throughout all 4 years of medical school.

Supporting children and youth during the COVID-19 pandemic and beyond: A rights-centred approach.

The COVID-19 pandemic is an unprecedented global crisis, affecting millions globally and in Canada. While efforts to limit the spread of the infection and 'flatten the curve' may buffer children and youth from acute illness, these public health measures may worsen existing inequities for those living on the margins of society. In this commentary, we highlight current and potential long-term impacts of COVID-19 on children and youth centring on the UN Convention of the Rights of the Child (UNCRC), with special attention to the accumulated toxic stress for those in difficult social circumstances. By taking responsive action, providers can promote optimal child and youth health and well-being, now and in the future, through adopting social history screening, flexible care models, a child/youth-centred approach to "essential" services, and continual advocacy for the rights of children and youth.

Evaluation of cognitive function in patients with severe anorexia nervosa before and after medical stabilization.

BACKGROUND: The purpose of this study was to quantify cognitive deficits in severe anorexia nervosa (AN) before and after medical stabilization. METHODS: This was a prospective study of 40 females between the ages of 18 and 50 admitted to a medical stabilization unit with severe AN (%IBW < 70). The primary outcome of the study was change in test scores on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) at baseline and after medical stabilization. RESULTS: There were no statistically significant differences in baseline RBANS scores between AN patients overall and controls (p = 0.0940). There was a statistically significant change in RBANS from baseline 94.1 + 12.7 to medical stabilization 97.1 + 10.6 (p = 0.0173), although notably both mean values fell within the average range. There were no significant differences in baseline RBANS scores between controls and AN-BP patients (p = 0.3320) but significant differences were found between controls and AN-R patients (p = 0.0434). CONCLUSIONS: No baseline deficits in cognition were found in this sample of women with severe AN.

The Role of Practice Diversification in the Growth of a Burn Center Network.

Practices within the Burn and Reconstructive Centers of America network have been organized to provide immediate and secondary reconstructive plastic surgery to burn patients. These reconstructive surgery abilities have been further engaged to expand these practices with non-burn-related surgical cases.Seven Burn and Reconstructive Centers of America practices were analyzed to quantitate the effects of nonburn reconstructive cases on practice growth over a 4-year period (2015-2018).All surgical cases were performed during the study period and were analyzed to identify burn-related procedures and procedures not related to burn injuries. Fifty-two percent of the cases were burn-related, whereas 48% were not burn-related. Over the 4-year period, burn cases increased by 46%, whereas nonburn cases increased by 84%. The overall percentage of nonburn cases increased from 43% in 2015 to 50% and 49% in 2017 and 2018.Nonburn cases contributed effectively to practice growth over this period. This practice model successfully engages broad reconstructive surgery skill sets to expand practice volumes.

Postexposure Prophylaxis With rVSV-ZEBOV Following Exposure to a Patient With Ebola Virus Disease Relapse in the United Kingdom: An Operational, Safety, and Immunogenicity Report.

BACKGROUND: In October 2015, 65 people came into direct contact with a healthcare worker presenting with a late reactivation of Ebola virus disease (EVD) in the United Kingdom. Vaccination was offered to 45 individuals with an initial assessment of high exposure risk. METHODS: Approval for rapid expanded access to the recombinant vesicular stomatitis virus-Zaire Ebola virus (rVSV-ZEBOV) vaccine as an unlicensed emergency medicine was obtained from the relevant authorities. An observational follow-up study was carried out for 1 year following vaccination. RESULTS: Twenty-six of 45 individuals elected to receive vaccination between 10 and 11 October 2015 following written informed consent. By day 14, 39% had seroconverted, increasing to 87% by day 28 and 100% by 3 months, although these responses were not always sustained. Neutralizing antibody responses were detectable in 36% by day 14 and 73% at 12 months. Common side effects included fatigue, myalgia, headache, arthralgia, and fever. These were positively associated with glycoprotein-specific T-cell but not immunoglobulin (Ig) M or IgG antibody responses. No severe vaccine-related adverse events were reported. No one exposed to the virus became infected. CONCLUSIONS: This paper reports the use of the rVSV-ZEBOV vaccine given as an emergency intervention to individuals exposed to a patient presenting with a late reactivation of EVD. The vaccine was relatively well tolerated, but a high percentage developed a fever ≥37.5°C, necessitating urgent screening for Ebola virus, and a small number developed persistent arthralgia.

Induction of RNA interference to block Zika virus replication and transmission in the mosquito Aedes aegypti.

The yellow fever mosquito, Aedes aegypti, serves as the primary vector for epidemic transmission of yellow fever, dengue, Zika (ZIKV), and chikungunya viruses to humans. Control of Ae. aegypti is currently limited to insecticide applications and larval habitat management; however, to combat growing challenges with insecticide resistance, novel genetic approaches for vector population reduction or transmission interruption are being aggressively pursued. The objectives of this study were to assess the ability of the Ae. aegypti antiviral exogenous-small interfering RNA (exo-siRNA) response to inhibit ZIKV infection and transmission, and to identify the optimal RNA interference (RNAi) target region in the ZIKV genome. We accomplished these objectives by in vitro transcription of five long double-stranded RNAs (dsRNAs) from the genome region spanning the NS2B-NS3-NS4A genes, which were the most highly conserved among ZIKV RNA sequences representing both East and West African and Asian-American clades, and evaluation of the ability of these dsRNAs to trigger an effective antiviral exo-siRNA response after intrathoracic injection into Ae. aegypti. In a pilot study, five ZIKV dsRNAs were tested by intrathoracic inoculation of 250 ng dsRNA into groups of approximately 5-day-old mosquitoes. Three days post-inoculation, mosquitoes were provided an infectious blood-meal containing ZIKV strain PRVABC59 (Puerto Rico), MR766 (Uganda), or 41525 (Senegal). On days 7 and 14 post-infection individual whole mosquito bodies were assessed for ZIKV infectious titer by plaque assays. Based on the results of this initial assessment, three dsRNAs were selected for further evaluation of viral loads of matched body and saliva expectorants using a standardized infectious dose of 1 × 107 PFU/mL of each ZIKV strain. Fourteen days post-exposure to ZIKV, paired saliva and carcass samples were harvested from individual mosquitoes and assessed for ZIKV RNA load by qRT-PCR. Injection of each of the three dsRNAs resulted in significant inhibition of replication of all three strains of ZIKV in mosquito bodies and saliva. This study lays critical groundwork for pursuing ZIKV transmission-blocking strategies that exploit the Ae. aegypti exo-siRNA response for arbovirus suppression in natural populations.

A Monoclonal Antibody Specific for Japanese Encephalitis Virus with High Neutralizing Capability for Inclusion as a Positive Control in Diagnostic Neutralization Tests.

Japanese encephalitis virus (JEV) is the most common cause of viral encephalitis in Asia, and it is increasingly a global public health concern because of its recent geographic expansion. Although commercial vaccines are available and used in some endemic countries, JEV continues to cause illness, with more than 60,000 cases reported annually. To develop a reproducible positive control antibody useable in diagnosis of JEV infections, murine hybridomas were developed from mice inoculated with a combination of IXIARO JEV vaccine and JEV domain III of the envelope protein (E-DIII). Monoclonal antibodies (MAbs) were characterized for their ability to neutralize virus in vitro. Monoclonal antibody 17BD3-2 was found to be JEV specific and highly neutralizing, with a plaque reduction neutralization test (PRNT)90 endpoint titer of 1.25 µg/mL. The functional epitopes were mapped using virus neutralization escape variants to amino acid residues S309, K312, and G333 in E-DIII. This MAb may be substituted for human immune sera used as a positive control in PRNT for distribution to public health laboratories worldwide in potential future outbreaks of JEV.

Impact of Nutritional Intake on Function in People with Mild-to-Moderate Multiple Sclerosis.

BACKGROUND: We sought to assess the associations between nutrition and ambulation, daily activity, quality of life (QOL), and fatigue in individuals with mild-to-moderate disability with multiple sclerosis (MS). METHODS: This cross-sectional pilot study included 20 ambulatory adult volunteers with MS (14 women and 6 men; mean ± SD age, 57.9 ± 10.2 years; mean ± SD Expanded Disability Status Scale score = 4.1 ± 1.8). Primary outcome variables included dietary assessment and the 6-Minute Walk Test (6MWT). Secondary measures included the Timed 25-Foot Walk test, Timed Up and Go test, daily activity, and three self-report questionnaires: the 12-item Multiple Sclerosis Walking Scale, the 36-item Short Form Health Survey (SF-36), and the Modified Fatigue Impact Scale. RESULTS: Significant correlations were seen between the percentage of diet comprising fats and the 6MWT (r = 0.51, P = .02) and the physical functioning component of the SF-36 (r = 0.47, P = .03). The percentage of carbohydrates was significantly correlated with the 6MWT (r = -0.43, P = .05), daily activity (r = -0.59, P = .005), and the physical functioning component of the SF-36 (r = -0.47, P = .03). Cholesterol, folate, iron, and magnesium were significantly positively correlated with the physical functioning component of the SF-36 and the 6MWT. CONCLUSIONS: These findings indicate better ambulation, daily function, and QOL with increased fat intake, decreased carbohydrate intake, and increased intake of the micronutrients cholesterol, folate, iron, and magnesium in people with mild-to-moderate MS. This pilot study highlights the potential impact of diet on function and QOL in MS.
