Vascularized axillary lymph node exchange: A manuscript design within the rat.
Planning and coordination among health-care professionals decrease readmission rates, yet workers have few opportunities to learn interprofessionally to improve transitions of care. An interprofessional readmission review curriculum engaged medical residents, pharmacy residents, nurse practitioner students, early-career nurses, and social work students in a critical analysis of readmissions. Learners (N = 98) participated in a 2 h, collaborative learning session to review health records from a patient readmitted within 30 days of discharge and determine plausible root causes for readmissions. A 5-item post-session survey completed by 83 (85%) evaluated knowledge and perceived competencies in transitions of care before and after participation. Significant improvements (p less then .001) occurred in ratings for all five items. Two open-ended questions captured learners' perceptions of understanding and appreciating the roles of other disciplines in the discharge process and importance of interprofessional communication. Several themes emerged including understanding gaps in the discharge process, improving interprofessional collaboration and communication, and paying more attention to discharge documentation. This innovative program helped build essential skills to ensure safe discharges by introducing learners to interprofessional perspectives in analyzing root causes for readmissions, strategies to improve discharge planning, and the value of team-based care.ABSTARCTPurpose To investigate ocular manifestations in patients positive for serum anti-neutrophil cytoplasmic antibodies (ANCAs) in Japan.Methods The clinical records of patients who had ocular manifestations and who were serum ANCA positive between 2011-2017 at Tokyo Medical and Dental University Hospital were retrospectively reviewed.Results Eighteen patients were identified to be positive for serum ANCA and had ocular manifestations, including optic nerve involvement (50%), scleritis (27.8%), iritis (27.8%), retinal vasculitis (16.7%), oculomotor disorder (16.7%), and peripheral ulcerative keratitis (11.1%). Six patients had ANCA-associated vasculitis (AAV), including 5 patients with granulomatosis with polyangiitis and 1 patient with microscopic polyangiitis. Most patients with optic nerve involvement were myeloperoxidase-ANCA positive. Contrastingly, most patients with anterior segment involvement were proteinase-3-ANCA positive.Conclusion Ocular manifestations were observed in some patients positive for serum ANCAs. Serum ANCA evaluation is useful for identifying the etiology of ocular inflammation and for diagnosing AAV, a life-threatening disease.RATIONALE The recent development of hyperpolarized 13C magnetic resonance spectroscopy has made it possible to measure cellular metabolism in vivo, in real time. OBJECTIVE By comparing participants with and without type 2 diabetes mellitus (T2DM), we report the first case-control study to use this technique to record changes in cardiac metabolism in the healthy and diseased human heart. METHODS AND RESULTS Thirteen people with T2DM (glycated hemoglobin, 6.9±1.0%) and 12 age-matched healthy controls underwent assessment of cardiac systolic and diastolic function, myocardial energetics (31P-magnetic resonance spectroscopy), and lipid content (1H-magnetic resonance spectroscopy) in the fasted state. In a subset (5 T2DM, 5 control), hyperpolarized [1-13C]pyruvate magnetic resonance spectra were also acquired and in 5 of these participants (3 T2DM, 2 controls), this was successfully repeated 45 minutes after a 75 g oral glucose challenge. Downstream metabolism of [1-13C]pyruvate via PDH (pyruvate dehydrogenase, [13C]bicarbonate), lactate dehydrogenase ([1-13C]lactate), and alanine transaminase ([1-13C]alanine) was assessed. Metabolic flux through cardiac PDH was significantly reduced in the people with T2DM (Fasted 0.0084±0.0067 [Control] versus 0.0016±0.0014 [T2DM], Fed 0.0184±0.0109 versus 0.0053±0.0041; P=0.013). In addition, a significant increase in metabolic flux through PDH was observed after the oral glucose challenge (P less then 0.001). As is characteristic of diabetes mellitus, impaired myocardial energetics, myocardial lipid content, and diastolic function were also demonstrated in the wider study cohort. CONCLUSIONS This work represents the first demonstration of the ability of hyperpolarized 13C magnetic resonance spectroscopy to noninvasively assess physiological and pathological changes in cardiac metabolism in the human heart. In doing so, we highlight the potential of the technique to detect and quantify metabolic alterations in the setting of cardiovascular disease.A key finding supporting a causal role of the immune system in the pathogenesis of hypertension is the observation that RAG1 knockout mice on a C57Bl/6J background (B6.Rag1-/-), which lack functional B and T cells, develop a much milder hypertensive response to Ang II (angiotensin II) than control C57Bl/6J mice. Here, we report that we never observed any Ang II resistance of B6.Rag1-/- mice purchased directly from the Jackson Laboratory as early as 2009. B6.Rag1-/- mice displayed nearly identical blood pressure increases monitored via radiotelemetry and hypertensive end-organ damage in response to different doses of Ang II and different levels of salt intake (0.02%, 0.3%, and 3% NaCl diet). Similarly, restoration of T-cell immunity by adoptive cell transfer did not affect the blood pressure response to Ang II in B6.Rag1-/- mice. Full development of the hypertension-resistant phenotype in B6.Rag1-/- mice appears to depend on the action of yet unidentified nongenetic modifiers in addition to the absence of functional T cells.Childhood vaccination is one of the greatest public health achievements of the 20th century, yet increasingly, parents question the safety of and need for vaccines. This has led to increased rates of vaccine delay and refusal and outbreaks of vaccine-preventable diseases. Physicians struggle with how to respond to families who refuse vaccines, as there are few known effective interventions to convince a family to vaccinate. In the United States, the practice of dismissing families for vaccine refusal appears to be increasing as a strategy for dealing with vaccine refusal. In this review, we review the literature surrounding this controversial practice, starting with the impact that vaccine-refusing families have on medical practices, followed by a review of dismissal policies of US physicians, and ending with a discussion of the ethics of this practice.Purpose The aim of the study was to investigate the effectiveness of social communication skills training (TBIconneCT) for people with traumatic brain injury (TBI) and their communication partners, delivered in-person or via telehealth, on quality of conversations. Method This study is a clinical trial, including an in-person intervention group (n = 17), a telehealth intervention group (n = 19), and a historical control group (n = 15). Participants were adults at least 6 months post moderate-to-severe TBI with social communication skills deficits and their usual communication partners. Participants completed a casual and purposeful conversation task at pre-intervention, postintervention, and a follow-up assessment. A blinded assessor evaluated conversations using the Adapted Measure of Participation in Conversation and the Adapted Measure of Support in Conversation. Treatment effects were examined by comparing groups on change in ratings between pre- and posttraining. Maintenance of effects was examined using change between posttraining and follow-up assessment. The trial protocol was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12615001024538). Results Trained participants with TBI had significant improvements in participation in casual conversation compared to controls. Trained communication partners also had significant improvements compared to controls on ratings of support in casual conversations. However, treatment effects were not maintained at follow-up for two of eight measures. Comparisons between outcomes of in-person and telehealth groups found negligible to small effect sizes for six of eight measures. Conclusions The findings reinforce previous studies demonstrating the efficacy of communication partner training after TBI. Telehealth delivery produced similar outcomes to in-person delivery.In this study we examined the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0 12-item version) in a mild traumatic brain injury (MTBI) sample.Materials and Methods Treatment-seeking adults (n = 131) with MTBI recruited from outpatient clinics in Vancouver Canada, were assessed 1- and 3-months following clinic intake. Dimensionality, reliability, and differential item functioning of the WHODAS 2.0 were examined with Rasch analysis. Associations between change in WHODAS 2.0 scores and symptom, work and perceived improvement outcomes were examined.Results Adequate fit to the Rasch model was achieved for 1-month follow-up assessment WHODAS 2.0 scores without altering the response format or item content [X2 (24, n = 130) = 21.2, p = .6]. The best model fit for 3-month follow-up assessment scores was achieved when two items (problems with dressing and washing) were combined [X2 (22, n = 115) = 20.9, p = .5]. Associations were evident between changes in WHODAS total Rasch scores and other outcome indicators such as return to productivity and percieved improvement.Conclusions The WHODAS 2.0 (12-item version) is a psychometrically sound measure of functional outcome for adults seeking treatment following MTBI. Our table of ordinal to interval score conversions is recommended for future research examining MTBI outcomes.This comprehensive review discusses clinical studies of patients following brain injuries (traumatic, acquired, or stroke), who have been treated with amantadine or memantine. Both amantadine and memantine are commonly used in the acute rehabilitation setting following brain injuries, despite their lack of FDA-approval for neuro-recovery. check details Given the broad utilization of such agents, there is a need to review the evidence supporting this common off-label prescribing. The purpose of this review is to describe the mechanisms of action for memantine and amantadine, as well as to complete a comprehensive review of the clinical uses of these agents. We included 119 original, clinical research articles from NCBI Medline, published before 2019. We focused on the domains of neuroplasticity, functional recovery, motor recovery, arousal, fatigue, insomnia, behavior, agitation, and cognition. Most of the existing research supporting the use of amantadine and memantine in recovery from brain injuries was done in very small populations, limiting the significance of conclusions. While most studies are positive; small effect sizes are usually reported, or populations are subject to bias. Furthermore, evidence is so limited that this review includes research regarding both acute and chronic acquired brain injury populations. Fortunately, reported short-term side effects generally are modest, and stop soon after amantadine/memantine is discontinued. However, responses are inconsistent, and the phenotype of responders remains elusive.
