“Assessment of Student Readiness for Clinical Education in Mixed-mode Curriculum Delivery: A Case Study”

Purpose – The purpose of this case study is to describe a simulation-based assessment designed to assure student readiness for a first full-time clinical experience in an entry-level Doctor of Physical Therapy program that transitioned to mixed-mode instruction during the COVID-19 pandemic. Design/methodology/approach – A cohort of 40 second-year physical therapy students whose content delivery mode, assessment methods and curricular sequence deviated from the curricular plan participated in a new assessment using standardized patients. The assessment was developed to preferentially address the knowledge, skills, abilities and professional behaviors (KSAs) that were typically assessed with other methods before the pandemic. Findings – The assessment was useful in identifying students who required additional learning experiences to meet expected levels of competence before transition to a first full-time clinical experience. It also identified KSAs that needed to be strengthened within the entire cohort of students. Research limitations/implications – This case study provides an example of feasible implementation of an assessment of student readiness for clinical education that may guide future development of standardized assessments in health profession education (HPE) programs that have or plan to transition to mixed-mode content delivery. Originality/value – This case study highlights the need and process for developing and implementing additional assessments in HPE programs when planned changes or unexpected variations in curriculum delivery occur. This evidence-based assessment preferentially addresses the affective domain of learning and includes competency standards that have recently been developed for physical therapy education in the USA

Use of type I interferon-inducible mRNAs as pharmacodynamic markers and potential diagnostic markers in trials with sifalimumab, an anti-IFNα antibody, in systemic lupus erythematosus

Type I interferons are implicated in the pathogenesis of systemic lupus erythematosus (SLE). Type I interferon-inducible mRNAs are widely and concordantly overexpressed in the periphery and involved tissues of a subset of SLE patients, and provide utility as pharmacodynamic biomarkers to aid dose selection, as well as potential indicators of patients who might respond favorably to anti-IFNα therapy in SLE. We implemented a three-tiered approach to identify a panel of type I interferon-inducible mRNAs to be used as potential pharmacodynamic biomarkers to aid dose selection in clinical trials of sifalimumab, an anti-IFNα monoclonal antibody under development for the treatment of SLE. In a single-dose escalation phase 1 trial, we observed a sifalimumab-specific and dose-dependent inhibition of the overexpression of type I interferon-inducible mRNAs in the blood of treated subjects. Inhibition of expression of type I interferon-inducible mRNAs and proteins was also observed in skin lesions of SLE subjects from the same trial. Inhibiting IFNα resulted in a profound downstream effect in these SLE subjects that included suppression of mRNAs of B-cell activating factor belonging to the TNF family and the signaling pathways of TNFα, IL-10, IL-1β, and granulocyte-macrophage colony-stimulating factor in both the periphery and skin lesions. A scoring method based on the expression of type I interferon-inducible mRNAs partitioned SLE patients into two distinct subpopulations, which suggests the possibility of using these type I interferon-inducible genes as predictive biomarkers to identify SLE patients who might respond more favorably to anti-type I interferon therapy

Medication and Dietary Supplement Interactions among a Low-Income, Hospitalized Patient Population Who Take Cardiac Medications

Purpose. To identify characteristics associated with the use of potentially harmful combinations of dietary supplements (DS) and cardiac prescription medications in an urban, underserved, inpatient population. Methods. Cardiac prescription medication users were identified to assess the prevalence and risk factors of potentially harmful dietary supplement-prescription medication interactions (PHDS-PMI). We examined sociodemographic and clinical characteristics for crude (χ2 or t-tests) and adjusted multivariable logistic regression associations with the outcome. Results. Among 558 patients, there were 121 who also used a DS. Of the 110 participants having a PHDS-PMI, 25% were asked about their DS use at admission, 75% had documentation of DS in their chart, and 21% reported the intention to continue DS use after discharge. A multivariable logistic regression model noted that for every additional medication or DS taken the odds of having a PHDS-PMI increase and that those with a high school education are significantly less likely to have a PHDS-PMI than those with a college education. Conclusion. Inpatients at an urban safety net hospital taking a combination of cardiac prescription medications and DS are at a high risk of harmful supplement-drug interactions. Providers must ask about DS use and should consider the potential for interactions when having patient discussions about cardiac medications and DS

Preconception exposures and adverse pregnancy, birth and postpartum outcomes:Umbrella review of systematic reviews

Background Preconception exposures have been associated with adverse pregnancy, birth and postpartum outcomes. However, the reports, statements and guidelines of national and international health organisations vary in what they recommend individuals should monitor, avoid, reduce or practise in the preconception period. Objectives To synthesise and evaluate the evidence across systematic reviews for associations between exposures before conception and adverse pregnancy, birth and postpartum outcomes. Data sources MEDLINE, Embase, Epistemonikos (to May 2020) and reference lists of included reviews, without language or date restrictions. Study selection, data extraction and synthesis Systematic literature reviews of observational and/or interventional studies reporting associations between preconception exposures in women and/or men of reproductive age and pregnancy, birth or postpartum health outcomes were included. The methodological quality of reviews and the certainty of the evidence underlying each exposure-outcome association were assessed using AMSTAR 2 and the GRADE approach. Results We identified 53 eligible reviews reporting 205 unique exposure-outcome associations. Methodological quality was generally low with only two reviews rated as ‘high’ quality and two as ‘moderate’. We found high-certainty, randomised trial evidence that maternal folate supplementation reduces the risk of neural tube defects and anomaly-related terminations. Moderate-certainty, observational evidence was found that maternal physical activity is associated with reduced risk of pre-eclampsia and gestational diabetes, and that paternal age of ≥40 years and maternal body mass index (BMI) and interpregnancy weight gain are associated with increased risk of various adverse pregnancy and birth outcomes. Low- and very low-certainty evidence was found for other associations. Conclusions Clinicians and policymakers can be confident that maternal folate supplementation should be encouraged during the preconception period. There is moderate certainty in the evidence base that maternal physical activity, BMI and interpregnancy weight gain and advanced paternal age are important preconception considerations. High-quality research is required to better understand other exposure-outcome associations

Non-Insertive Acupuncture and Neonatal Abstinence Syndrome: A Case Series from an Inner City Safety Net Hospital

OBJECTIVE: We report on the safety of non-insertive acupuncture (NIA) in 54 newborns diagnosed with Neonatal Abstinence Syndrome (NAS) in a busy inner city hospital. METHODS: For this case series, a retrospective chart review was conducted. Data on participant demographics, number of NIA treatments, provider referrals, and outcomes of interest (sleeping, feeding, and adverse events) were collected. RESULTS: Of the 54 newborns receiving NIA, 86% were non-Hispanic White; 87% were on Medicaid, and gestational age ranged from 33.2 to 42.1 weeks. Out of 54 chart reviews, a total of 92 NIA sessions were documented ranging from 1 to 6 sessions per infant. Of the total number of treatments (n = 92), 73% were requested by a physician. Chart reviews reported restless infants calmed down during NIA, babies slept through or fell asleep immediately following NIA, and better feeding was noted following NIA. There were no adverse events noted in the medical records. CONCLUSIONS: This retrospective chart review shows potential for the use of NIA as an adjunctive treatment in newborns with NAS symptoms during hospitalization. More research is necessary to study whether the incorporation of NIA can result in positive outcomes in newborns withdrawing from narcotics

Health literacy and complementary and alternative medicine use among underserved inpatients in a safety net hospital

Little is known about the relationship between health literacy and complementary and alternative medicine (CAM) use in low-income racially diverse patients. The authors conducted a secondary analysis of baseline data from 581 participants enrolled in the Re-Engineered Discharge clinical trial. The authors assessed sociodemographic characteristics, CAM use, and health literacy. They used bivariate and multivariate logistic regression to test the association of health literacy with four patterns of CAM use. Of the 581 participants, 50% reported using any CAM, 28% used provider-delivered CAM therapies, 27% used relaxation techniques, and 21% used herbal medicine. Of those with higher health literacy, 55% used CAM. Although there was no association between health literacy and CAM use for non-Hispanic Black participants, non-Hispanic White (OR = 3.68, 95% CI [1.27, 9.99]) and Hispanic/other race (OR = 3.40, 95% CI [1.46, 7.91]) participants were significantly more likely to use CAM if they had higher health literacy. For each racial/ethnic group, there were higher odds of using relaxation techniques among those with higher health literacy. Underserved hospitalized patients use CAM. Regardless of race, patients with high health literacy make greater use of relaxation techniques

Are all threats equal? Associations of childhood exposure to physical attack versus threatened violence with preadolescent brain structure

Background: Neurodevelopmental studies of childhood adversity often define threatening experiences as those involving harm or the threat of harm. Whether effects differ between experiences involving harm (“physical attack”) versus the threat of harm alone (“threatened violence”) remains underexplored. We hypothesized that while both types of experiences would be associated with smaller preadolescent global and corticolimbic brain volumes, associations with physical attack would be greater. Methods: Generation R Study researchers (the Netherlands) acquired T1-weighted scans from 2905 preadolescent children, computed brain volumes using FreeSurfer, and asked mothers whether their children ever experienced physical attack (n = 202) or threatened violence (n = 335). Using standardized global (cortical, subcortical, white matter) and corticolimbic (amygdala, hippocampus, anterior cingulate cortex, orbitofrontal cortex) volumes, we fit confounder-adjusted models. Results: Physical attack was associated with smaller global volumes (βcortical=−0.14; 95% CI: −0.26, −0.02); βwhite matter= −0.16; 95% CI: − 0.28, − 0.03) and possibly some corticolimbic volumes, e.g., βamygdala/ICV-adjusted= −0.10 (95% CI: −0.21, 0.01). We found no evidence of associations between threatened violence and smaller volumes in any outcome; instead, such estimates were small, highly uncertain, and positive in direction. Conclusions: Experiences of physical attack and threatened violence may have quantitively different neurodevelopmental effects. Thus, differences between types of threatening experiences may be neurodevelopmentally salient.</p

Behavioral and neurostructural correlates of childhood physical violence victimization:Interaction with family functioning

Violence victimization may cause child behavior problems and neurostructural differences associated with them. Healthy family environments may buffer these effects, but neural pathways explaining these associations remain inadequately understood. We used data from 3154 children (x̅age  = 10.1) to test whether healthy family functioning moderated possible associations between violence victimization, behavior problems, and amygdala volume (a threat-responsive brain region). Researchers collected data on childhood violence victimization, family functioning (McMaster Family Assessment Device, range 0-3, higher scores indicate healthier functioning), and behavior problems (Achenbach Child Behavior Checklist [CBCL] total problem score, range 0-117), and they scanned children with magnetic resonance imaging. We standardized amygdala volumes and fit confounder-adjusted models with "victimization × family functioning" interaction terms. Family functioning moderated associations between victimization, behavior problems, and amygdala volume. Among lower functioning families (functioning score = 1.0), victimization was associated with a 26.1 (95% confidence interval [CI]: 9.9, 42.4) unit higher CBCL behavior problem score, yet victimized children from higher functioning families (score = 3.0) exhibited no such association. Unexpectedly, victimization was associated with higher standardized amygdala volume among lower functioning families (ŷ = 0.5; 95% CI: 0.1, 1.0) but lower volume among higher functioning families (ŷ = -0.4; 95% CI: -0.7, -0.2). Thus, healthy family environments may mitigate some neurobehavioral effects of childhood victimization.</p

Diet-induced obesity leads to behavioral indicators of pain preceding structural joint damage in wild-type mice

Introduction: Obesity is one of the largest modifiable risk factors for the development of musculoskeletal diseases, including intervertebral disc (IVD) degeneration and back pain. Despite the clinical association, no studies have directly assessed whether diet-induced obesity accelerates IVD degeneration, back pain, or investigated the biological mediators underlying this association. In this study, we examine the effects of chronic consumption of a high-fat or high-fat/high-sugar (western) diet on the IVD, knee joint, and pain-associated outcomes. Methods: Male C57BL/6N mice were randomized into one of three diet groups (chow control; high-fat; high-fat, high-sugar western diet) at 10 weeks of age and remained on the diet for 12, 24, or 40 weeks. At endpoint, animals were assessed for behavioral indicators of pain, joint tissues were collected for histological and molecular analysis, serum was collected to assess for markers of systemic inflammation, and IBA-1, GFAP, and CGRP were measured in spinal cords by immunohistochemistry. Results: Animals fed obesogenic (high-fat or western) diets showed behavioral indicators of pain beginning at 12 weeks and persisting up to 40 weeks of diet consumption. Histological indicators of moderate joint degeneration were detected in the IVD and knee following 40 weeks on the experimental diets. Mice fed the obesogenic diets showed synovitis, increased intradiscal expression of inflammatory cytokines and circulating levels of MCP-1 compared to control. Linear regression modeling demonstrated that age and diet were both significant predictors of most pain-related behavioral outcomes, but not histopathological joint degeneration. Synovitis was associated with alterations in spontaneous activity. Conclusion: Diet-induced obesity accelerates IVD degeneration and knee OA in mice; however, pain-related behaviors precede and are independent of histopathological structural damage. These findings contribute to understanding the source of obesity-related back pain and the contribution of structural IVD degeneration

A Two-Phase Innate Host Response to Alphavirus Infection Identified by mRNP-Tagging In Vivo

A concept fundamental to viral pathogenesis is that infection induces specific changes within the host cell, within specific tissues, or within the entire animal. These changes are reflected in a cascade of altered transcription patterns evident during infection. However, elucidation of this cascade in vivo has been limited by a general inability to distinguish changes occurring in the minority of infected cells from those in surrounding uninfected cells. To circumvent this inherent limitation of traditional gene expression profiling methods, an innovative mRNP-tagging technique was implemented to isolate host mRNA specifically from infected cells in vitro as well as in vivo following Venezuelan equine encephalitis virus (VEE) infection. This technique facilitated a direct characterization of the host defense response specifically within the first cells infected with VEE, while simultaneous total RNA analysis assessed the collective response of both the infected and uninfected cells. The result was a unique, multifaceted profile of the early response to VEE infection in primary dendritic cells, as well as in the draining lymph node, the initially targeted tissue in the mouse model. A dynamic environment of complex interactions was revealed, and suggested a two-step innate response in which activation of a subset of host genes in infected cells subsequently leads to activation of the surrounding uninfected cells. Our findings suggest that the application of viral mRNP-tagging systems, as introduced here, will facilitate a much more detailed understanding of the highly coordinated host response to infectious agents
