RESUMEN

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.

RESUMEN

Social prescribing is a means for trusted individuals in clinical and community settings to connect people who have non-medical, health-related social needs to non-clinical supports and services within the community through a non-medical prescription. Evaluations of social prescribing programs for the pediatric population have demonstrated statistically significant improvements in participants' mental, physical, and social wellbeing and reductions in healthcare demand and costs. Experts have pointed to the particularly powerful impact of social prescribing on children's mental health, suggesting that it may help to alleviate the strain on the overburdened mental health system. Social prescribing shows promise as a tool to move pediatric care upstream by addressing non-medical, health-related social needs, hence why there is an urgent need to direct more attention towards the pediatric population in social prescribing research, policy, and practice. This demands rapid action by researchers, policymakers, and child health professionals to support advancements in this area.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Langerhans cells (LCs) are sentinels of skin's immune system, their loss from epidermis contributing to UVR suppression of cell-mediated immunity (CMI). Omega-3 polyunsaturated fatty acids show potential to reduce UVR suppression of CMI in mice and humans, potentially through modulation of LC migration. Our objectives were to examine whether eicosapentaenoic acid (EPA) ingestion influences UV-mediated effects on epidermal LC numbers and levels of immunomodulatory mediators including prostaglandin (PG)D2 , which is expressed by LC. In a double-blind randomised controlled study, healthy individuals took 5-g EPA-rich (n=40) or control (n=33) lipid for 12 weeks; UVR-exposed and unexposed skin samples were taken pre- and postsupplementation. Epidermal LC numbers were assessed by immunofluorescence for CD1a, and skin blister fluid PG and cytokines were quantified by LC-MS/MS and Luminex assay, respectively. Presupplementation, UVR reduced mean (SEM) LC number/mm2 from 913 (28) to 322 (40) (P<.001), and mean PGD2 level by 37% from 8.1 (11.6) to 5.1 (5.6) pg/µL; P<.001), while IL-8 level increased (P<.001). Despite confirmation of EPA bioavailability in red blood cells and skin in the active group, no between-group effect of EPA was found on UVR modulation of LC numbers, PGD2 or cytokine levels postsupplementation. Thus, no evidence was found for EPA reduction of photoimmunosuppression through an impact on epidermal LC numbers. Intriguingly, UVR exposure substantially reduced cutaneous PGD2 levels in humans, starkly contrasting with reported effects of UVR on other skin PG. Lowered PGD2 levels could reflect LC loss from the epidermis and/or altered dendritic cell activity and may be relevant for phototherapy of skin disease.

RESUMEN

INTRODUCTION: Intrathecal baclofen (ITB) screening assesses response to a test dose of ITB on spasticity and function and identifies adverse reactions. METHOD: An expert panel consulted on best practices after conducting an extensive literature search and conducting an online survey. RESULTS: A successful trial may confirm predetermined goals, which may include improved mobility/positioning, decreased time/improved independence for activities, less home exercise, better wheelchair tolerance, decreased caregiver time, improved sleep, and reduced pain, or may modify goals and expectations. Individuals should not be tested in the presence of active medical issues (e.g., MS exacerbations, active urinary tract infection, nonhealing wounds). Oral antispasmodics can be weaned before trial if a goal is to eliminate them. The standard baclofen test dose is a 50-mcg bolus, 25 mcg in very small children or patients who rely on spasticity for mobility. Patients unresponsive to the standard dose may require 75 mcg or 100 mcg; 24 hours should elapse between bolus doses. Cardiopulmonary parameters should be checked frequently during the first two hours postinjection, and spasticity measures assessed at least twice within four hours. Observation continues until the patient is stable and recovers from hypertonia. Adverse events include spinal headaches, nausea/vomiting, urinary retention, hypotension, seizures, drowsiness/sedation, respiratory depression, and coma. Before implantation, team members must discuss starting dose, drug concentration, delivery mode, pump size and location, and catheter tip placement. Patients/caregivers should understand the commitment necessary for ITB therapy. CONCLUSIONS: Screening helps identify appropriate candidates for ITB.

RESUMEN

OBJECTIVE: The purposes of this study were to assess the feasibility of and to create a referral mechanism for a diagnostic radiology consultation clinic. SUBJECTS AND METHODS: A pilot program was instituted with patients from a single primary care clinic over a 3-week period. Patients with findings of common problems at routine imaging, such as atherosclerosis, emphysema, and hepatic steatosis, were eligible to participate. As the patients arrived for their routine primary care visits, office staff informed them of the opportunity to formally meet with a radiologist to review their most recent imaging findings. The office staff of the primary care clinic then contacted the radiologist covering the diagnostic radiology consultation clinic to schedule a consultation. A survey was administered before and after the session. RESULTS: Twenty-two patients participated (88% participation rate). Participants rated the consultation as very helpful (mean, 4.8 on 1-5 scale), and all participants would take the opportunity to review studies with the radiologist again. Significantly more patients preferred the involvement of the radiologist in communicating the results of an imaging examination after the consultation compared with before the consultation (p = 0.001). After the consultation session, patients had significantly improved understanding of a radiologist's role (p = 0.004), and all participants were able to correctly identify the radiologist as a physician who interprets medical images. CONCLUSION: A referral mechanism for a diagnostic radiology consultation clinic can be effectively integrated into the everyday workflow of both the referring physician and the radiologist. The consultations are useful to patients and help to increase their awareness of the role of the radiologist.

RESUMEN

Hepatitis E virus infection is an emerging disease in developed countries. Acute and chronic infection has been reported, with chronic infection being increasingly reported in immunocompromised patients. Neurological disorders are an emerging manifestation of both acute and chronic hepatitis E virus infection. We report a 77-year-old female presented with paraesthesia and was found to have abnormal liver function tests. Serology was found to be positive for hepatitis E virus IgM, IgG and RNA. Liver function tests normalised after three weeks and her neurological symptoms completely resolved. To our knowledge, this is the first case in Scotland of hepatitis E virus presenting only with neurological symptoms.

RESUMEN

This study assessed the personality of severely ill patients with anorexia nervosa, restricting (AN-R) and binge-purge subtypes (AN-BP), during hospitalization for medical stabilization. Participants (N = 37) completed the Temperament and Character Inventory, Revised. Personality domains were similar between AN-R and AN-BP with the exception of cooperativeness. AN-R patients scored higher on this dimension, suggesting that individuals with restricting anorexia may be more tolerant of treatment during early medical stabilization. Future research is needed to further elucidate this novel finding in order to identify the point at which body mass index predicts a decline in cooperativeness and the potential need for new intervention strategies.

RESUMEN

The long-chain n-3 PUFA, EPA, is believed to be important for skin health, including roles in the modulation of inflammation and protection from photodamage. FFQ and blood levels are used as non-invasive proxies for assessing skin PUFA levels, but studies examining how well these proxies reflect target organ content are lacking. In seventy-eight healthy women (mean age 42·8, range 21-60 years) residing in Greater Manchester, we performed a quantitative analysis of long-chain n-3 PUFA nutrition estimated from a self-reported FFQ (n 75) and correlated this with n-3 PUFA concentrations in erythrocytes (n 72) and dermis (n 39). Linear associations between the three n-3 PUFA measurements were assessed by Spearman correlation coefficients and agreement between these measurements was estimated. Average total dietary content of the principal long-chain n-3 PUFA EPA and DHA was 171 (SD 168) and 236 (SD 248) mg/d, respectively. EPA showed significant correlations between FFQ assessments and both erythrocyte (r 0·57, P< 0·0001) and dermal (r 0·33, P= 0·05) levels, as well as between erythrocytes and dermis (r 0·45, P= 0·008). FFQ intake of DHA and the sum of n-3 PUFA also correlated well with erythrocyte concentrations (r 0·50, P< 0·0001; r 0·27, P= 0·03). Agreement between ranked thirds of dietary intake, blood and dermis approached 50% for EPA and DHA, though gross misclassification was lower for EPA. Thus, FFQ estimates and circulating levels of the dietary long-chain n-3 PUFA, EPA, may be utilised as well-correlated measures of its dermal bioavailability.

RESUMEN

Green tea catechins (GTC) reduce UV radiation (UVR)-induced inflammation in experimental models, but human studies are scarce and their cutaneous bioavailability and mechanism of photoprotection are unknown. We aimed to examine oral GTC cutaneous uptake, ability to protect human skin against erythema induced by a UVR dose range and impact on potent cyclo-oxygenase- and lipoxygenase-produced mediators of UVR inflammation, PGE2 and 12-hydroxyeicosatetraenoic acid (12-HETE), respectively. In an open oral intervention study, sixteen healthy human subjects (phototype I/II) were given low-dose GTC (540 mg) with vitamin C (50 mg) daily for 12 weeks. Pre- and post-supplementation, the buttock skin was exposed to UVR and the resultant erythema quantified. Skin blister fluid and biopsies were taken from the unexposed and the UVR-exposed skin 24 h after a pro-inflammatory UVR challenge (three minimal erythema doses). Urine, skin tissue and fluid were analysed for catechin content and skin fluid for PGE2 and 12-HETE by liquid chromatography coupled to tandem MS. A total of fourteen completing subjects were supplement compliant (twelve female, median 42.5 years, range 29-59 years). Benzoic acid levels were increased in skin fluid post-supplementation (P= 0.03), and methylated gallic acid and several intact catechins and hydroxyphenyl-valerolactones were detected in the skin tissue and fluid. AUC analysis for UVR erythema revealed reduced response post-GTC (P= 0.037). Pre-supplementation, PGE2 and 12-HETE were UVR induced (P= 0.003, 0.0001). After GTC, UVR-induced 12-HETE reduced from mean 64 (sd 42) to 41 (sd 32) pg/µl (P= 0.01), while PGE2 was unaltered. Thus, GTC intake results in the incorporation of catechin metabolites into human skin associated with abrogated UVR-induced 12-HETE; this may contribute to protection against sunburn inflammation and potentially longer-term UVR-mediated damage.

RESUMEN

OBJECTIVE: There is considerable interest in improving radiology reporting practices through peer review, and the inclusion of structured feedback from referring physicians may improve this process. The purpose of this article is to evaluate the feasibility of this type of novel peer-review system. MATERIALS AND METHODS: Five referring physicians from our institution participated as reviewers. Reports from abdominal CT, chest CT, brain MRI, and abdominal ultrasound were eligible for review if the indication was "abdominal pain," "shortness of breath," "headache," and "pain," respectively. Reports were excluded if the examinations were normal or ordered as follow-up. Forty-eight reports (12 from each group) were then selected at random and distributed to the referring physicians along with the clinical scenario and an evaluation form for each examination. RESULTS: The reports were found to be clinically useful (average, 3.8 on a 1-5 scale), allowing for good confidence in clinical decision making (average, 3.7). The most common problems were unclear language, typographical errors, and reports that did not answer the clinical question. Of the reports, 35.4% contained recommendations for further diagnosis or treatment, and 84.7% of these recommendations were deemed clinically appropriate. The participating physicians thought that the results of 31.2% of the examinations should have been directly communicated to the ordering provider. CONCLUSION: Radiology reports and recommendations were clinically useful, even though problems with language, typographical errors, answering the clinical question, and direct communication of examination results were identified. Structured feedback from referring physicians is a novel approach to the peer-review process that may identify problems that go unnoticed by the radiologist, thereby improving reporting practices.

RESUMEN

Nucleic acid amplification methods such as the PCR have had a major impact on the diagnosis of viral infections, often achieving greater sensitivities and shorter turnaround times than conventional assays and an ability to detect viruses refractory to conventional isolation methods. Their effectiveness is, however, significantly influenced by assay target sequence variability due to natural diversity and rapid sequence changes in viruses that prevent effective binding of primers and probes. This was investigated for a diverse range of enteroviruses (EVs; species A to D), human rhinoviruses (HRVs; species A to C), and human parechovirus (HPeV) in a multicenter assay evaluation using a series of full-length prequantified RNA transcripts. RNA concentrations were quantified by absorption (NanoDrop) and fluorescence methods (RiboGreen) prior to dilution in buffer supplemented with RNase inhibitors and carrier RNA. RNA transcripts were extremely stable, showing minimal degradation after prolonged storage at temperatures between ambient and -20°C and after multiple freeze-thaw cycles. Transcript dilutions distributed to six referral laboratories were screened by real-time reverse transcriptase PCR assays using different primers and probes. All of the laboratories reported high assay sensitivities for EV and HPeV transcripts approaching single copies and similar amplification kinetics for all four EV species. HRV detection sensitivities were more variable, often with substantially impaired detection of HRV species C. This could be accounted for in part by the placement of primers and probes to genetically variable target regions. Transcripts developed in this study provide reagents for the ongoing development of effective diagnostics that accommodate increasing knowledge of genetic heterogeneity of diagnostic targets.
