Tramadol and duloxetine, reuptake inhibitors of serotonin and noradrenaline, are widely used analgesics. Cytoplasmic serotonin in human platelets reportedly regulates the activity of low-molecular-weight GTP-binding proteins via serotonylation, leading to the modulation of platelet functions. We recently showed that the combination of thrombopoietin and collagen in the low doses synergistically induces human platelet activation via Rac and Rho/Rho-kinase.

Article Synopsis
  • The study evaluates the effectiveness of the 7-Item Japan Urgent Stroke Triage (JUST-7) in emergency medical services for stroke patients, comparing its use alongside the Cincinnati Prehospital Stroke Scale (CPSS).
  • Data analysis from two periods (CPSS alone vs. CPSS + JUST-7) revealed that adding JUST-7 did not change ambulance transport times, but it improved specificity in identifying strokes and major artery occlusions.
  • The findings suggest that while JUST-7 shows potential for enhancing prehospital stroke diagnostics, it requires careful adaptation of cut-off values based on local conditions to maximize its benefits in different healthcare environments.

The success rate of flap tissue reconstruction has increased in recent years owing to advancements in microsurgical techniques. However, complications, such as necrosis, are still more prevalent in diabetic patients compared to non-diabetic individuals, presenting an ongoing challenge. To address this issue, many previous studies have examined vascular anastomoses dilation and stability, primarily concerning surgical techniques or drugs.

Article Synopsis
  • - Acute kidney injury (AKI) has a high fatality rate (8.6%) and is commonly seen in ICU patients; early diagnosis and intervention are crucial, with urinary L-FABP potentially useful for diagnosing AKI.
  • - A study involving 100 trauma patients measured urinary L-FABP levels at 6 and 12 hours post-injury, using two protocols to evaluate the results and identify AKI cases.
  • - Out of the patients studied, 15 were diagnosed with AKI, showing a strong correlation between L-FABP levels and AKI diagnosis, suggesting that taking measurements at both time points improves accuracy compared to just one measurement at 6 hours.

Article Synopsis
  • A patient in his 40s with severe COVID-19 pneumonia was given acupuncture to help improve his breathing and reduce reliance on mechanical ventilation after extensive medical treatments failed.
  • Acupuncture sessions, administered four times a week, resulted in improved respiratory metrics and enabled a gradual transition from more invasive ventilation modes to less invasive support.
  • The treatment ultimately led to complete discontinuation of mechanical ventilation after eight acupuncture sessions, suggesting that acupuncture may be a helpful adjunctive therapy for patients with respiratory failure from severe pneumonia.

Background: Given the widespread prevalence of the coronavirus disease 2019 (COVID-19), oral and neck examinations tend to be avoided in patients with suspected or confirmed COVID-19. This might delay the diagnosis of conditions such as Lemierre's syndrome, which involves symptoms resembling COVID-19-related throat manifestations.

Case Presentation: A 24-year-old man without any underlying conditions was diagnosed with COVID-19 7 days before presentation.

Intradialytic hypotension and arrhythmias are complications of hemodialysis. They are associated with decreased intravascular volume due to reduced ultrafiltration volume, cardiac function, and arterial tone. The vascular endothelial glycocalyx, which exists on the surface of healthy vascular endothelial cells and maintains vascular permeability, has been suggested to be impaired by hemodialysis.

CXCL12, belonging to the CXC chemokine family, is a weak agonist of platelet aggregation. We previously reported that the combination of CXCL12 and collagen at low doses synergistically activates platelets via not CXCR7 but CXCR4, a specific receptor for CXCL12 on the plasma membrane. Recently, we reported that not Rho/Rho kinase, but Rac is involved in the platelet aggregation induced by this combination.
