Background. Aspirin is an antiplatelet used for the secondary prevention after vascular events. It is also suggested for the primary prevention of vascular events in high risk people, however, despite using standard prophylactic doses, aspirin resistance may result in therapeutic failure and arterial thrombosis. Since the prevalence of aspirin resistance and its associated factors were heterogeneous in different studies, this study was conducted to determine the prevalence and associated factors of aspirin resistance in an Iranian population under aspirin for primary prevention of vascular events. Methods. 264 patients without documented vascular disease with 80 mg daily aspirin consumption for at least one month enrolled in this cross-sectional study. Aspirin resistance was assessed by the measurement of thromboxane B2 in the urine samples using the enzyme-linked immunosorbent assay method. Aspirin resistance was defined as a urine level of thromboxane B2 ≥ 1700 ng/dl. Results. The prevalence of aspirin resistance in this study was 9.8%. Age (OR = 0.935, 95% CI: 0.880-0.993, P = 0.028) and geographical regions (OR = 0.117, 95% CI: 0.014-0.958, P = 0.045) showed independent correlation with aspirin resistance. No significant association observed between aspirin resistance and gender, diabetes mellitus, hypertension, hyperlipidemia, smoking, duration of aspirin use, body mass index, and drug history. Conclusions. Despite the standard daily dose of aspirin for primary prevention of vascular events, some of our patients exhibited aspirin resistance that was directly related to a higher age and geographical region. More studies are required to clarify the beneficial role of aspirin resistance test before planning a preventive strategy in high risk individuals.

Background and Aim: Traumatic Spinal Cord Injury (SCI) is one of the most traumatic events threatening patients’ well-being and places a financial burden on health care system. The first step in determination of the exact impact of SCI is to estimate the pattern of traumatic injuries in a population and also the type of frequently occurred co-injuries. Hence, this study was conducted to assess the frequency of anatomy, type of spine injuries, and associated co-injuries in patients with trauma in Poursina Hospital of Guilan province in Iran. Methods and Materials/Patients: A descriptive cross-sectional study was carried out on traumatic spine patients admitted to the Poursina hospital of Rasht, a referral therapeutic center for trauma in north of Iran, in Rasht during 2015 to 2019. Data were extracted from the SCI registry of Poursina Hospital, Rasht, Guilan, Iran. Results: A total of 274 records were reviewed. Seventy-six patients were females and 198 patients were males. Mean±SD of age of the patients was 42.27±16.83 years. Based on this survey, most of the patients (43.8%) had SCI in lumbar region. Locked facet was seen in 12 patients. Fifty-seven patients (20.8%) complained about having pain. The median of VAS score was 6 (range=6). Co-existence of associated injuries (e.g. limb fractures, TBI, Internal bleeding, etc.) was found in 27.4% of the patients. According to ASIA (The American Spinal Injury Association) impairment scale, three patients (2.9%) had score A, and 100 patients (97.1%) had score E neurological defects. Conclusion: The most telling reiteration to be drawn is that men mostly suffered from spine trauma. Lumbar region was the most susceptible location of SCI. Moreover, most of the patients experienced score E (normal neurological charcteristics) according to ASIA.
