RESUMEN

Description of case: We report a case of Tropheryma whipplei endocarditis, a rare cause of bloodculture-negative infective endocarditis (BCNIE). Due to its rarity and lack of availability of diagnostic tests in district hospitals, the diagnosis remains challenging. The objective of this case report is to increase physician awareness of this pathogen. A 61-year-old man presented to the Emergency Department with central chest pain at rest. A 12-lead ECG demonstrated ST- segment depression in V4-V6 leads, and his serial troponin levels were raised. He was commenced on treatment for acute coronary syndrome and transferred to the Coronary Care Unit. An echocardiogram showed a 15mm x 15mm vegetation in the aortic valve with mild aortic regurgitation. His initial microbiology workup, which included two sets of blood cultures (pre-antibiotics), MRSA screen & COVID-19 PCR, was negative. He was transferred to a cardiothoracic centre four days later. Pre-operative CT coronary angiogram showed severe three vessel coronary artery disease. He underwent triple coronary artery by-pass grafts and tissue aortic valve replacement. During early post-op recovery, he had fever episodes and an elevated C-reactive protein of 280 mg/L but normal white cell counts. He was treated with intravenous Tazocin for hospital-acquired pneumonia and discharged on doxycycline. Two weeks post-discharge, he had a positive 16S/18S PCR for Tropheryma whipplei on molecular analysis of the aortic valve. He was treated for Whipples endocarditis with a 4-week course of IV Ceftriaxone, followed by a 12-month course of oral Cotrimoxazole. The patient has reported doing well since the surgery. Discussion(s): Molecular assay with PCR of the heart valve is the mainstay of diagnosing Whipple's endocarditis. There have been 5 previously reported cases of Whipple's endocarditis in the United Kingdom in our knowledge. It is likely under-reported because of a reliance on tissue diagnosis. Preceding intestinal manifestations and arthralgia should raise its clinical suspicion for timely workup. Physician awareness of Whipple's Endocarditis is paramount in investigating for this pathogen.

RESUMEN

BACKGROUND: COVID-19 is an ongoing virus disease also recognized as a coronavirus pandemic that propelled the world to rethink organizational strategies during this unprecedented challenge. Although research on CSR has broadly been done over the past decades;nonetheless, how CSR can contribute a leading role in engaging the stakeholders such as customers during this pandemic period and post-pandemic is an important research gap that ought to be uncovered. OBJECTIVES: This study explores the impact of CSR on external stakeholders like customers and how organizations can dramatically sustain the relationships during the COVID-19 period. First, this study investigates the relationships between CSR and customer satisfaction (CS). Second, this study explores the relationships between CSR and customer retention (CR). Finally, the moderating impact of gender and education were examined among the proposed relationships. METHODS: Using the survey of 500 respondents, this study prospected the linkages among CSR, CS, and CR from China using a convenience sampling approach. The questionnaires were disseminated to Chinese online shoppers between Jan 2020 and March 2020 and explored using SEM model. RESULTS: It found that customers are more attached and satisfied with those organizations that are socially responsible and value their stakeholders, especially during uncertain situations like COVID-19 since presently revealed a positive relationship between CSR and CS. Second, it is found that there is a positive influence of CSR on CR as well. Finally, the study affirmed the positive nexus of gender and education as the moderators among CSR, CR, and CS. CONCLUSION: CSR is always on the front line blending social and environmental goals into business operations, especially during uncertain times and challenges. Undeniably, the COVID-19 pandemic is not only a global health emergency but is also leading to a major global challenge that drives organizations to revisit policies to sustain the relationships with their stakeholders. This study concluded the positive nexus of CSR and affirmed the positive role in sustaining relationships with customers during distinct uncertainties like COVID-19.

RESUMEN

Systemic inflammation is a hallmark of severe coronavirus disease-19 (COVID-19). Anti-inflammatory therapy is considered crucial to modulate the hyperinflammatory response (cytokine storm) in hospitalized COVID-19 patients. There is currently no specific, conclusively proven, cost-efficient, and worldwide available anti-inflammatory therapy available to treat COVID-19 patients with cytokine storm. The present study aimed to investigate the treatment benefit of oral colchicine for hospitalized COVID-19 patients with suspected cytokine storm. Colchicine is an approved drug and possesses multiple anti-inflammatory mechanisms. This was a pilot, open-label randomized controlled clinical trial comparing standard of care (SOC) plus oral colchicine (colchicine arm) vs. SOC alone (control arm) in non-ICU hospitalized COVID-19 patients with suspected cytokine storm. Colchicine treatment was initiated within first 48 hours of admission delivered at 1.5 mg loading dose, followed by 0.5 mg b.i.d. for next 6 days and 0.5 mg q.d. for the second week. A total of 96 patients were randomly allocated to the colchicine (n=48) and control groups (n=48). Both colchicine and control group patients experienced similar clinical outcomes by day 14 of hospitalization. Treatment outcome by day 14 in colchicine vs control arm: recovered and discharged alive: 36 (75.0%) vs. 37 (77.1%), remain admitted after 14-days: 4 (8.3%) vs. 5 (10.4%), ICU transferred: 4 (8.3%) vs. 3 (6.3%), and mortality: 4 (8.3%) vs. 3 (6.3%). The speed of improvement of COVID-19 acute symptoms including shortness of breath, fever, cough, the need of supplementary oxygen, and oxygen saturation level, was almost identical in the two groups. Length of hospitalization was on average 1.5 day shorter in the colchicine group. There was no evidence for a difference between the two groups in the follow-up serum levels of inflammatory biomarkers including C-reactive protein (CRP), D-dimer, lactate dehydrogenase (LDH), ferritin, interleukin-6 (IL-6), high-sensitivity troponin T (hs-TnT) and N-terminal pro b-type natriuretic peptide (NT pro-BNP). According to the results of our study, oral colchicine does not appear to show clinical benefits in non-ICU hospitalized COVID-19 patients with suspected cytokine storm. It is possible that the anti-inflammatory pathways of colchicine are not crucially involved in the pathogenesis of COVID-19.
