Objectives: Diabetes mellitus is one of the major risk factors for cardiovascular disease, and increases the risk of postoperative mortality. HbA1c is a measure of glycemic control. This study aimed to determine the effect of glycemic status on the complications of coronary artery bypass graf (CABG) surgery in diabetic patients. Methods: This cross-sectional study was performed on 300 diabetic patients including 186 (62%) men and 114 (38%) women who underwent CABG from March 2010 to August 2011 and selected via census method. Preoperative blood glucose control status was determined using HbA1c levels, and the patients were evaluated for postoperative in-hospital complications. Results: The mean age of the patients was 62.3±  6.9 years. In-hospital mortality was 1.0% (3/300). New-onset atrial fibrillation was the most common complication (35%). HbA1c level above 7.5% was a predictor of in-hospital mortality after CABG (unadjusted odds ratio 1.9, 95٪ CI: 1.1-3.2, p = 0.006). After stratifying analysis with Chi-sqaure test we found that gender history of myocardial infarction had no significant relationship with HbA1c level in two groups with or without complication. Conclusions: Long-term uncontrolled blood glucose before CABG is associated with increased postoperative complications. Preoperative HbA1c measurement can be a predictor of high-risk patients.

BackgroundInformation from pulse oximeter waves confirms the presence of a pulse and helps obtain waves from tissue when the supplying artery is not readily accessible.ObjectivesThis study determined the predictive value of pulse oximeters for detecting improved arterial pulses after angiography.Patients and MethodsThis cross-sectional, multi-center study included 467 4-day-old to 12-year-old patients and was conducted from January 2012 to January 2016. Angiographies were performed on 12-year-old or younger children for various medical reasons using venous, arterial, or both types of paths. The posterior malleolar or dorsalis pedis were palpated in punctured lower extremities. In the absence of a pulse, pulse oximetry was performed to identify pulse curves at 1 hour, 6 hours, and 12 hours after each angiography.ResultsPulse oximetry displayed the pulses of 319 patients immediately following each angiography. Of these, 262 patients had palpable pulses at 6 hours after angiography (P < 0.0001), while 57 patients had no palpable pulse. Of these 57 patients, 15 had no palpable pulse at 12 hours after angiography (P < 0.0001). The odds of pulse improvement in children 6 hours after catheter angiography were 76% for the arterial path, 90% for the venous path, and 83.2% for both paths. At 12 hours after catheter angiography, these values increased to 91.6% for the arterial path, 100% for the venous path, and 95.9% for both paths.ConclusionsThe pulse oximeter can display the pulse curve immediately (1 hour) after angiography and indicate pulse improvement at 12 hours maximally following an angiography. In this case, heparin alone may be used instead of thrombolytic agents.

Introduction: Stroke is the third most common cause of death in developed countries and is the most common neurological disabling disease. Today, several risk factors are known for stroke including lifestyle and risk factors such as hypertension and diabetes which differ in cultures and countries. The aim of this study was to determine the frequency of ischemic stroke in patients admitted to the brain department of Ghaem Hospital in 1395. Methods: In this observational cohort study, 201 cases of ischemic stroke who confirmed by neurologists as well as imaging techniques for diagnosis patients hospitalized to the neurology section of Ghaem Hospital, Mashhad, Iran During 1395.  The Patients' information such as age, sex, and The place of living and also the type of stroke and its main risk factors, including history of stroke in the past, hypertension, diabetes mellitus, high blood sugar cigar and high blood lipids were extracted from their records and completed in the checklist. 1 year follow up performed by telephone calling. Data were analyzed and examined by SPSS 21 and statistical tests. Results: According to the analysis, except for the cigarette variable (P-value = 0.003) HDL and TG (P-value = 0.001), no significant relationship was found between the other risk factors of disease risk and sex. In this study, 201 patients with ischemic stroke were studied. The mean age of the participants in the study was 50.92 years. In this study, the prevalence of stroke in men were higher than that of women, 104 (51.7%) for males and 97 (48.3%) for women. In the study of the most important clinical risk factors for stroke, the results showed that the highest prevalence was hypertension in women with 68 (70.1%) and the least of them was smoking with 16 (16.5%). The mean annual death rate in this study was 15.9%, which did not have a significant relationship with sex groups. Conclusion: In this study, hypertension, having diabetes and high blood glucose levels were the most important risk factors for stroke in patients, these results are in accordance with the previous finding studies. Regarding the results, it seems that the control of blood pressure and diabetes is not effectively considered, which requires further investigation.
