Relationships among adult playfulness, stress, and coping during the COVID-19 pandemic.

The COVID-19 pandemic created high levels of stress that negatively affect mental health and well-being. The stress and coping process is influenced by individual difference factors, such as personality, that impact perceptual processes and emotional reactions. Adult playfulness is a personality characteristic that may lead to better mental and physical health outcomes. We test a theoretical model to determine whether the two factors of perceived stress, perceived self-efficacy (PSE) and perceived helplessness (PH), mediate the relationship among playfulness and coping in adults (N = 694). Scores on the Perceived Stress Scale were high indicating high levels of pandemic-related stress. The SEM model demonstrated direct effects of playfulness on PSE, PH, adaptive, maladaptive, and supportive coping. Both dimensions of perceived stress were partial mediators in the relationship among playfulness and coping outcomes. Findings illustrate the pathways by which adult playfulness can amplify or attenuate the impact of stress perceptions on coping strategies. The importance of building psychological resources such as playfulness to boost adaptive outcomes in stressful situations such as the COVID-19 pandemic is discussed.

Association between COVID-19 diagnosis and presenting chief complaint from New York City triage data.

BACKGROUND AND AIM: New York City (NYC) is an epicenter of the COVID-19 pandemic in the United States. Proper triage of patients with possible COVID-19 via chief complaint is critical but not fully optimized. This study aimed to investigate the association between presentation by chief complaints and COVID-19 status. METHODS: We retrospectively analyzed adult emergency department (ED) patient visits from five different NYC hospital campuses from March 1, 2020 to May 13, 2020 of patients who underwent nasopharyngeal COVID-19 RT-PCR testing. The positive and negative COVID-19 cohorts were then assessed for different chief complaints obtained from structured triage data. Sub-analysis was performed for patients older than 65 and within chief complaints with high mortality. RESULTS: Of 11,992 ED patient visits who received COVID-19 testing, 6524/11992 (54.4%) were COVID-19 positive. 73.5% of fever, 67.7% of shortness of breath, and 65% of cough had COVID-19, but others included 57.5% of weakness/fall/altered mental status, 55.5% of glycemic control, and 51.4% of gastrointestinal symptoms. In patients over 65, 76.7% of diarrhea, 73.7% of fatigue, and 69.3% of weakness had COVID-19. 45.5% of dehydration, 40.5% of altered mental status, 27% of fall, and 24.6% of hyperglycemia patients experienced mortality. CONCLUSION: A novel high risk COVID-19 patient population was identified from chief complaint data, which is different from current suggested CDC guidelines, and may help triage systems to better isolate COVID-19 patients. Older patients with COVID-19 infection presented with more atypical complaints warranting special consideration. COVID-19 was associated with higher mortality in a unique group of complaints also warranting special consideration.

Topical glyceryl trinitrate for the treatment of tendinopathies: a systematic review.

OBJECTIVE: To produce a best evidence synthesis of the clinical effects of topical glyceryl trinitrate (GTN) in the treatment of tendinopathies. DESIGN: A systematic review of published randomised controlled trials (RCTs) of the use of GTN in patients with tendinopathy. DATA SOURCES: MEDLINE, Embase, Scopus and CINAHL from database inception to January 2018. METHODS: We examined RCTs comparing the effects of topical GTN with either placebo or other treatments on tendinopathy. Overall quality of each eligible study was determined based on a combined assessment of internal validity, external validity and precision. The level of evidence for each assessed parameter was rated based on the system by van Tulder et al. RESULTS: A total of 10 eligible RCTs were identified including patients with tendinopathy of the rotator cuff (n=4), wrist extensors (n=3), Achilles (n=2) and patellar (n=1) tendons. For all tendinopathies, improvements in pain were significant when comparing GTN versus placebo in the short term (<8 weeks; poor evidence). Significant improvements in midterm outcomes for treatment with GTN versus placebo included the following: patient satisfaction (strong evidence); chances of being asymptomatic with activities of daily living (strong evidence); range of movement (moderate evidence); strength (moderate evidence); pain (at night and with activity; poor evidence) and local tenderness (poor evidence). Patients treated with topical GTN reported a higher incidence of headaches than those who received placebo (moderate evidence). CONCLUSIONS AND RELEVANCE: Treatment of tendinopathies with topical GTN for up to 6 months appears to be superior to placebo and may therefore be a useful adjunct to the treating healthcare professions.

The proteome and phosphoproteome of circulating extracellular vesicle-enriched preparations are associated with characteristic clinical features in type 1 diabetes.

Introduction: There are no validated clinical or laboratory biomarkers to identify and differentiate endotypes of type 1 diabetes (T1D) or the risk of progression to chronic complications. Extracellular vesicles (EVs) have been studied as biomarkers in several different disease states but have not been well studied in T1D. Methods: As the initial step towards circulating biomarker identification in T1D, this pilot study aimed to provide an initial characterization of the proteomic and phosphoproteomic landscape of circulating EV-enriched preparations in participants with established T1D (N=10) and healthy normal volunteers (Controls) (N=7) (NCT03379792) carefully matched by age, race/ethnicity, sex, and BMI. EV-enriched preparations were obtained using EVtrap® technology. Proteins were identified and quantified by LC-MS analysis. Differential abundance and coexpression network (WGCNA), and pathway enrichment analyses were implemented. Results: The detected proteins and phosphoproteins were enriched (75%) in exosomal proteins cataloged in the ExoCarta database. A total of 181 proteins and 8 phosphoproteins were differentially abundant in participants with T1D compared to controls, including some well-known EVproteins (i.e., CD63, RAB14, BSG, LAMP2, and EZR). Enrichment analyses of differentially abundant proteins and phosphoproteins of EV-enriched preparations identified associations with neutrophil, platelet, and immune response functions, as well as prion protein aggregation. Downregulated proteins were involved in MHC class II signaling and the regulation of monocyte differentiation. Potential key roles in T1D for C1q, plasminogen, IL6ST, CD40, HLA-DQB1, HLA-DRB1, CD74, NUCB1, and SAP, are highlighted. Remarkably, WGCNA uncovered two protein modules significantly associated with pancreas size, which may be implicated in the pathogenesis of T1D. Similarly, these modules showed significant enrichment for membrane compartments, processes associated with inflammation and the immune response, and regulation of viral processes, among others. Discussion: This study demonstrates the potential of proteomic and phosphoproteomic signatures of EV-enriched preparations to provide insight into the pathobiology of T1D. The WGCNA analysis could be a powerful tool to discriminate signatures associated with different pathobiological components of the disease.

Biopsychosocial approach to tendinopathy.

Tendinopathy describes a spectrum of changes that occur in damaged tendons, leading to pain and reduced function that remains extremely challenging for all clinicians. There is an increasing awareness of the influence that psychological and psychosocial components, such as self-efficacy and fear-avoidance, have on rehabilitation outcomes in musculoskeletal medicine. Although it is widely accepted that psychological/psychosocial factors exist in tendinopathy, there is currently a distinct lack of trials measuring how these factors affect clinical outcomes. Biopsychosocial treatments acknowledge and address the biological, psychological and social contributions to pain and disability are currently seen as the most efficacious approach to chronic pain. Addressing and modulating these factors are crucial in the pathway of personalised treatments in tendinopathy and offer a real opportunity to drive positive outcomes in patients. In this education review, we also provide the current evidence-based guidance on psychological and psychosocial developments in musculoskeletal medicine and how these may be translated to treating tendinopathy using a biopsychosocial model.

First-Line Vasopressor and Mortality Rates in ED Patients with Acute Drug Overdose.

INTRODUCTION: While emergency department (ED) visits for acute drug overdose are at an all-time high, the importance of vasopressors to treat circulatory shock in this patient population remains unclear. This study investigated the association between first-line vasopressor and mortality, for both push-dose and infusion, in this patient population. METHODS: From a prospective cohort of consecutive ED patients with drug overdose at two urban teaching centers over 5 years, we performed a secondary data analysis of patients with circulatory shock, defined as hypotension requiring either vasopressors, high-dose insulin euglycemia therapy, or both. The first-line vasopressor (push-dose and infusion) was analyzed for associations with the primary outcome (in-hospital mortality) and secondary outcomes (24-hour mortality, ICU LOS). Subgroup analysis of beta-/calcium-channel blocker overdose was performed to evaluate impact of antidotal therapies. Data analysis included multivariable regression. RESULTS: Fifty-five patients with circulatory shock were analyzed, in whom there was 20% 24-hour mortality, 42% in-hospital mortality, 730-minute mean vasopressor duration, and 53.4-hour median ICU LOS. On multivariable analysis, there was significantly decreased adjusted odds of in-hospital mortality with first-line push-dose phenylephrine (aOR 0.06, CI 0.01-0.55), and significantly increased adjusted odds of in-hospital mortality with first-line push-dose epinephrine (aOR 60.8, CI 6.1-608). Of the first-line infusions, norepinephrine had the lowest odds of in-hospital mortality (aOR 0.80, CI 0.2-3.1). CONCLUSIONS: In ED patients with undifferentiated drug overdose and circulatory shock, the first-line vasopressor is associated with in-hospital mortality. First-line push-dose phenylephrine was associated with the lowest odds of in-hospital mortality. Future randomized studies are warranted for validation.

Effectiveness of isometric exercise in the management of tendinopathy: a systematic review and meta-analysis of randomised trials.

OBJECTIVE: To systematically review and critically appraise the literature on the effectiveness of isometric exercise in comparison with other treatment strategies or no treatment in tendinopathy. DESIGN: A systematic review and meta-analysis of randomised controlled trials. DATA SOURCES: Electronic searches of Medline, Cumulative Index to Nursing and Allied Health Literature, EMBASE and Cochrane were undertaken from inception to May 2020. METHODS: Overall quality of each study was determined based on a combined assessment of internal validity, external validity and precision. For each outcome measure, level of evidence was rated based on the system by van Tulder et al. RESULTS: Ten studies were identified and included in the review, including participants with patellar (n=4), rotator cuff (n=2), lateral elbow (n=2), Achilles (n=1) and gluteal (n=1) tendinopathies. Three were of good and seven were of poor overall quality. Based on limited evidence (level 3), isometric exercise was not superior to isotonic exercise for chronic tendinopathy either immediately following treatment or in the short term (≤12 weeks) for any of the investigated outcome measures. Additionally, for acute rotator cuff tendinopathy, isometric exercise appears to be no more effective than ice therapy in the short term (limited evidence; level 3). SUMMARY: Isometric exercise does not appear to be superior to isotonic exercise in the management of chronic tendinopathy. The response to isometric exercise is variable both within and across tendinopathy populations. Isometric exercise can be used as part of a progressive loading programme as it may be beneficial for selected individuals. PROSPERO REGISTRATION NUMBER: CRD42019147179.

Isometric versus isotonic exercise for greater trochanteric pain syndrome: a randomised controlled pilot study.

OBJECTIVES: Greater trochanteric pain syndrome (GTPS) is a common cause of lateral hip pain. Limited evidence exists for the effectiveness of exercise for GTPS. This study aimed to compare the effectiveness of isometric and isotonic exercise for individuals with GTPS. METHODS: This randomised controlled pilot trial recruited 30 participants with GTPS. Both programmes consisted of daily, progressive home exercise for 12 weeks with 8 individual physiotherapy sessions over the trial period. The primary outcome measure was the Victorian Institute of Sport Assessment-Gluteal (VISA-G) and secondary outcome measures included the Numeric Pain Rating Scale (0-10) and an 11-point Global Rating of Change Scale. Outcome measures were assessed at baseline, 4 and 12 weeks. RESULTS: Twenty-three participants completed the trial. After 12 weeks, mean VISA-G scores improved in both groups; 55-65 in the isometric group and 62-72 in the isotonic group. 55% of the isometric group and 58% of the isotonic group achieved a reduction in pain of at least 2 points (minimally clinically important difference (MCID)) on the Numeric Pain Rating Scale. 64% of the isometric group and 75% of the isotonic group had improved by at least 2 points (MCID) on the Global Rating of Change Scale. CONCLUSION: Isometric and isotonic exercise programmes appear to be effective for individuals with GTPS and should be considered in the loading management of patients with this condition.

How does surgery compare to sham surgery or physiotherapy as a treatment for tendinopathy? A systematic review of randomised trials.

PURPOSE: To assess the effectiveness of surgery on all tendinopathies by comparing it to no treatment, sham surgery and exercise-based therapies for both mid-term (12 months) and long-term (> 12 months) outcomes. METHODS: Our literature search included EMBASE, Medline, CINAHL and Scopus. A combined assessment of internal validity, external validity and precision of each eligible study yielded its overall study quality. Results were considered significant if they were based on strong (Level 1) or moderate (Level 2) evidence. RESULTS: 12 studies were eligible. Participants had the following types of tendinopathy: shoulder in seven studies, lateral elbow in three, patellar in one and Achilles in one. Two studies were of good, four of moderate and six of poor overall quality. Surgery was superior to no treatment or placebo, for the outcomes of pain, function, range of movement (ROM) and treatment success in the short and midterm. Surgery had similar effects to sham surgery on pain, function and range of motion in the midterm. Physiotherapy was as effective as surgery both in the midterm and long term for pain, function, ROM and tendon force, and pain, treatment success and quality of life, respectively. CONCLUSION: We recommend that healthcare professionals who treat tendinopathy encourage patients to comply with loading exercise treatment for at least 12 months before the option of surgery is seriously entertained.
