Multimodal Therapy for the Treatment of Severe Ischemic Stroke Combining Endovascular Embolectomy and Stenting of Long Intracranial Artery Occlusion
Embolic occlusion of cerebral arteries is a major cause for stroke. Intravenous thrombolysis showed positive results in this condition, however even when strict criteria are used, the risk of hemorrhagic transformation is possible. Microsurgical embolectomy has been described earlier.
Purpose. We performed multimodal therapy of cerebral artery occlusion.
Case Report. We present a case of a 49-year-old female patient whoâaccording to the National Institute of Health Stroke Scale (NIHSS)âwas rated as 19 due to acute occlusion of the horizontal segment of the left middle cerebral artery (MCA). After failed i.v. thrombolysis, only a part of the clot could be evacuated by the endovascular approachâwithout restoration of blood flow. Normal patency of the left MCA was re-established after stenting. Within 72 hours, the patient had an NIHSS score of 14, with a small haematoma in the left hemisphere.
Conclusion. In our case multimodal therapy combining i.v. thrombolysis, mechanical disruption of thrombus, MCA stenting and platelet function antagonists, resulted in successful recanalization of the acutely occluded left MCA

Poor glycaemic control is associated with reduced exercise performance and oxygen economy during cardio-pulmonary exercise testing in people with type 1 diabetes
BackgroundTo explore the impact of glycaemic control (HbA1c) on functional capacity during cardio-pulmonary exercise testing in people with type 1 diabetes.MethodsSixty-four individuals with type 1 diabetes (age: 34 ¹ 8 years; 13 females, HbA1c: 7.8 ¹ 1% (62 ¹ 13 mmol/mol), duration of diabetes: 17 ¹ 9 years) performed a cardio-pulmonary cycle ergometer exercise test until volitional exhaustion. Stepwise linear regression was used to explore relationships between HbA1c and cardio-respiratory data with p ⤠0.05. Furthermore, participants were divided into quartiles based on HbA1c levels and cardio-respiratory data were analysed by one-way ANOVA. Multiple regression analysis was performed to explore the relationships between changes in time to exhaustion and cardio-respiratory data. Data were adjusted for confounder.ResultsHbA1c was related to time to exhaustion and oxygen consumption at the power output elicited at the sub-maximal threshold of the heart rate turn point (r = 0.47, R2 = 0.22, p = 0.03). Significant differences were found at time to exhaustion between QI vs. QIV and at oxygen consumption at the power output elicited at the heart rate turn point between QI vs. QII and QI vs. QIV (p < 0.05). Changes in oxygen uptake, power output and in oxygen consumption at the power output elicited at the heart rate turn point and at maximum power output explained 55% of the variance in time to exhaustion (r = 0.74, R2 = 0.55, p < 0.01).ConclusionsPoor glycaemic control is related to less economical use of oxygen at sub-maximal work rates and an earlier time to exhaustion during cardio-pulmonary exercise testing. However, exercise training could have the same potential to counteract the influence of poor glycaemic control on functional capacity

The effect of inhaling concentrated oxygen on performance during repeated anaerobic exercise
The objective of the pilot study was to test the effect of inhaling 99.5% oxygen on recovery. The source of concentrated oxygen was O-PUR (Oxyfit). Research subjects completed two thirty-second Wingate tests at an interval of ten minutes, and in the interval between the tests the subjects inhaled either oxygen or a placebo in random order. This procedure was then repeated. The pilot study revealed a significantly (p<0.03) smaller performance drop in the second Wingate test following the inhalation of 99.5% oxygen when compared with the placebo. The results of the study indicate that inhaling concentrated oxygen may have a positive effect on short-term recovery processes
