Point To Area of Pain: A Clinically Useful Telehealth Physical Exam Technique for Focal Nociceptive and Neuropathic Pain.

BACKGROUND: Chronic pain is a leading cause of disease burden and disability globally. The COVID-19 pandemic catalyzed a major paradigm shift in health care delivery with the universal adoption of telemedicine. Telehealth physical examination is particularly challenging and little guidance is available on this topic. OBJECTIVES: We attempt to describe the Point To the Area of Pain (PTAP) test and establish a consensus regarding its utility for musculoskeletal examination (MSK) via telehealth. STUDY DESIGN: The authors drafted an online survey. SETTING: The survey was sent to physicians and nurse practitioners within the authors' respective departments and institutions who routinely use telemedicine to treat pain METHODS: Respondents (n = 61) were asked about their primary specialty, comfort level in evaluating patients in pain, use of the PTAP test and its perceived clinical relevance to patient management, and other relevant questions. RESULTS: Respondents were predominantly trained in Physiatry (47.5%), Anesthesiology (23%), Neurology (13.1%) and Family Medicine (11.5%); 67.2% of providers treat pain related diseases > 75% of the time; 50.8% of respondents were "somewhat comfortable" at performing a virtual MSK exam and 29.5% were "not comfortable"; 65.5% utilize the PTAP test and 88.5% agree or strongly agree that this test provides extrinsic clinically relevant information. LIMITATIONS: The relatively small number of respondents. CONCLUSION: PTAP tests should not replace the standard accepted in-person or virtual physical examination in practice, but in the absence of a hands-on exam, the PTAP test is a clear and concise test that can easily be performed in conjunction with other techniques via telehealth, and in the context of assessing pain provides useful clinical information that can help guide medical decision making.

A retrospective analysis of a commercially available platelet-rich plasma kit during clinical use.

INTRODUCTION: Point-of-care analyses of platelet-rich plasma (PRP) are not routine in the orthopedic regenerative medicine field. Therefore, many physicians rely on the manufacturer's reported content for commercial preparation kits. This contributes to a knowledge gap between injectate content and patient outcome. OBJECTIVE: To assess whether the EmCyte PurePRP II 60-mL preparation kit returns PRP content that meets the manufacturer's expectations when used during routine clinical care for a heterogenous patient population, and to determine whether a change in PRP yield volume affects injectate content. Protocol A (exclusion of granulocytes and low hematocrit) and Protocol B (inclusion of granulocytes and higher hematocrit) were evaluated. DESIGN: Retrospective review. SETTING: Private practice. PARTICIPANTS: One hundred five patients (118 preparations) treated for orthopedic conditions over an 8-month period via PRP injection. Thirteen patients had two independently made preparations on different treatment days that qualified for analysis. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Complete blood count (absolute counts and calculated fold enrichment from baseline of platelets, white blood cells, red blood cells, granulocytes, lymphocytes, monocytes; and hematocrit levels). Confounding variables included age, gender, and preparation yield volume. RESULTS: During routine clinical use, the cellular content of both Protocols A and B met or exceeded the manufacturer's expectations of platelet enrichment and granulocyte inclusion or exclusion. Hematocrit values were slightly higher than anticipated from Protocol A preparations. The modification of yield volume from 7 to 4 mL led to a significant difference in platelet enrichment without affecting absolute cell counts (2.88; 95% confidence interval [CI] 1, 4.76; P = .003). Both gender and age moderately affected the level of platelet enrichment from baseline but did not significantly affect absolute platelet counts. CONCLUSION: In the absence of widespread characterization, confirming the variation in commercial PRP kits during clinical use is crucial.

Profiling of immune dysfunction in COVID-19 patients allows early prediction of disease progression.

With a rising incidence of COVID-19-associated morbidity and mortality worldwide, it is critical to elucidate the innate and adaptive immune responses that drive disease severity. We performed longitudinal immune profiling of peripheral blood mononuclear cells from 45 patients and healthy donors. We observed a dynamic immune landscape of innate and adaptive immune cells in disease progression and absolute changes of lymphocyte and myeloid cells in severe versus mild cases or healthy controls. Intubation and death were coupled with selected natural killer cell KIR receptor usage and IgM+ B cells and associated with profound CD4 and CD8 T-cell exhaustion. Pseudo-temporal reconstruction of the hierarchy of disease progression revealed dynamic time changes in the global population recapitulating individual patients and the development of an eight-marker classifier of disease severity. Estimating the effect of clinical progression on the immune response and early assessment of disease progression risks may allow implementation of tailored therapies.

Migrant labour, racism and the British National Health Service.

This study explores the dynamics of racism, specifically its generation and reproduction as an ideology, and its role in affecting the reception and occupational location of migrant medical labour in Britain. It is argued that the treatment of 'overseas doctors' in Britain draws on a complex interplay between racism and nationalism underpinned by the historical construction of 'welfarism' as a moral legitimator of 'Britishness'. Through an exploration of internal and external immigration controls introduced with the aim of regulating migrant labour, we demonstrate how British social policy and elite discourses of 'race' combine to construct moral prescriptions of threat such that migrants and British-born 'non-whites' entering the British medical profession are forced to negotiate 'saviour/pariah' ascriptions indicative of discriminatory but contradictory processes specific to the operation of the British National Health Service as a normative institution.
