RESUMEN
The pandemic of COVID-19 caused worldwide concern. Due to the lack of appropriate medications and the inefficiency of commercially available vaccines, lots of efforts are being made to develop de novo therapeutic modalities. Besides this, the possibility of several genetic mutations in the viral genome has led to the generation of resistant strains such as Omicron against neutralizing antibodies and vaccines, leading to worsening public health status. Exosomes (Exo), nanosized vesicles, possess several therapeutic properties that participate in intercellular communication. The discovery and application of Exo in regenerative medicine have paved the way for the alleviation of several pathologies. These nanosized particles act as natural bioshuttles and transfer several biomolecules and anti-inflammatory cytokines. To date, several approaches are available for the administration of Exo into the targeted site inside the body, although the establishment of standard administration routes remains unclear. As severe acute respiratory syndrome coronavirus 2 primarily affects the respiratory system, we here tried to highlight the transplantation of Exo in the alleviation of COVID-19 pathologies.

Recently, cytokines belonging to C1q/tumour necrosis factor-related proteins (CTRPs) superfamily have attracted increasing attention due to multiple metabolic functions and desirable anti-inflammatory effects. These various molecular effectors exhibit key roles upon the onset of cardiovascular diseases, making them novel adipo/cardiokines. This review article aimed to highlight recent findings correlated with therapeutic effects and additional mechanisms specific to the CTRP9, particularly in cardiac ischaemia/reperfusion injury (IRI). Besides, the network of the CTPR9 signalling pathway and its possible relationship with IRI were discussed. Together, the discovery of all involved underlying mechanisms could shed light to alleviate the pathological sequelae after the occurrence of IRI.

OBJECTIVES: Severe complications of tramadol overdose have been reported; however, few large-scale studies have investigated this issue. Therefore, this study aimed to explore the presentation and complications of tramadol overdose in patients admitted to an intoxication referral center in northwestern Iran. METHODS: Patients with tramadol overdose admitted to Sina Teaching Hospital in Tabriz, Iran during 2013-2017 were included. For each patient, the following data were collected: demographics, previous drug or medication overdose, whether the patient was in the process of quitting drug use, ingested dose of tramadol and co-ingestants, Glasgow Coma Scale (GCS) score, clinical symptoms at the time of admission, and admission characteristics. Serotonin toxicity was diagnosed in patients who fit the Hunter criteria. Multiple logistic regression was performed to identify variables associated with the incidence of severe complications of tramadol overdose. RESULTS: In total, 512 cases of tramadol overdose were evaluated, of which 359 patients were included, with a median age of 41 years (range, 16-69) and a median tramadol dose of 1,500 mg (range, 500-4,000). The most frequent complications associated with tramadol overdose were hypertension (38.4%), tachycardia (24.8%), and seizure (14.5%). No serotonin toxicity was detected in patients. Having a GCS score <15, having taken a tramadol dose of >1,000 mg, being in the process of quitting drug use, being 30-49 years old, and male sex were significantly related to the incidence of severe complications of tramadol overdose. CONCLUSIONS: Although seizure was prevalent among Iranian patients with tramadol poisoning, serotonin toxicity and cardiogenic shock were rare findings.

BACKGROUND: Atrial fibrilation (AF) is the most common complication following heart surgeries; it often occurs in patients after coronary artery bypass graft (CABG). The purpose of this review is to categorize prophylaxes or treatment by administration of Amiodaron in patients with CABG. DATA RESOURCES: We searched google scholar, pubmed, and Cochrane Library databases (the period 1970-2010) for articles on Amiodaron in CABG and cardiac surgery. A total of 1 561 articles were identified, and 30 articles met the criteria and were enrolled in this review. RESULTS: Most studies supported Amiodarone for prophylaxi purpose in patients who were performed with CABG; few papers supported Amiodaron as a drug for treating CABG. The prophylaxis can decrease the incidence rate of AF in CABG, but if it uses as a treatment, the side effect of Amiodaron will decrease because all of the patients will not get Amiodarone. In the other hand use of Amiodarone as a treatment does not influence the length of hospital stay significantly but these kinds of study are so few. CONCLUSION: No appropriate therapeutic method has been defined for AF. At present, the common way of treating AF following cardiac surgery is mainly based on prophylaxis in medical books and references.

RESUMEN
BACKGROUND: This randomized, clinical trial evaluates the analgesic and safety of paracetamol and Morphine in management of headache. OBJECTIVES: This study aimed to evaluate the analgesic and safety effects of intravenous single dose of paracetamol, versus morphine in post trauma headache in emergency departments. PATIENTS AND METHODS: This study was a single-center, prospective, randomized, double-blind clinical trial conducted on two groups treated with intravenous paracetamol and intravenous morphine. Thirty patients were enrolled in each group. Patients (18-55 years-old adults) complaining from headaches due to pure trauma were included in the study. The inclusion criteria required patients to have headachesof more than 40 mm on a 100 mm visual analogue scale without any pathological findings in their clinical examinations and imaging studies. RESULTS: Mean duration required to treat the headache was 37.43 and 71.93 minutes in the groups administered paracetamol (group A) and morphine (group B), respectively. After 15 minutes of treatment, this changed to 31.7 ± 18.0 mm (95% CI 8.2 to 25.2) and 48.3 ± 14.1 mm (95% CI 8.2 to 25.2) in groups A and B, respectively. Headache of the patients of group A significantly mitigated in comparison with group B (P < 0.005). Headache of group Apatients was significantly mitigated 30 minutes after treatment (P < 0.005). CONCLUSIONS: Intravenous paracetamol is an effective and safe treatment for patients admitted to the emergency department with headaches caused by head trauma.
