Objective We examined cardiac surgery patients who underwent monitoring of postoperative vital parameters using medical monitoring devices which transferred data to a mobile application and a web‐based software. Methods From November 2017 to November 2020, a total of 2340 patients were enrolled in the remote patient monitoring system after undergoing cardiac surgery. The medical devices recorded vital parameters, such as blood pressure, pulse rate, saturation, body temperature, blood glucose, and electrocardiography were measured via the Health Monitor DakikApp and Holter ECG DakikApp devices which reported data to web‐based software and a mobile application (DakikApp Mobile Systems, Remscheid, Germany). During the follow‐up period, patients were contacted daily through text and voice messages, and video conferences. Remote Medical Evaluations (RMEs) concerning patients' medical states were performed. Medication reminders, daily treatment were communicated to the patients with the DakikApp Mobile Systems Software. Results During a mean follow‐up period of 78.9 ± 107.1 (10–395) days, a total of 135,786 patient contacts were recorded (782 video conferences, 2805 voice messaging, and 132,199 text correspondence). The number of RMEs handled by the Telemedicine Team was 79,560. A total of 105,335 vital parameter measurements were performed and 5024 hospital application requests (6.3% per RME) were addressed successfully and hospitalization was avoided. A total of 144 (6.1%) potentially life‐threatening complications were found to have been diagnosed early using the Telemedicine System. Conclusion Remote Patient Monitoring Systems combined with professional medical devices are feasible, effective, and safe for the purpose of improving postoperative outcomes.

Blunt traumatic cardiac rupture is rare and associated with high mortality. The most popular theory of cardiac rupture after blunt thoracic trauma is rapid deceleration with disruption of the atria from their connections to the vena cava and pulmonary veins. In cases with both massive hemothorax and hemopericardium, injury can usually originate from the heart and/or major vessels. Surgical approach through the median sternotomy can provide convenience to repair the defect. In this article, successful treatment with median sternotomy of a 33-year-old male case with a rupture of the left atrium after blunt thoracic trauma was reported.

The brachiocephalic artery is an alternative cannulation site in the repair of ascending aortic lesions that require circulatory arrest. We evaluate the effectiveness and safety of this technique. Proximal aortic surgery was performed in 32 patients from 2006 through 2012 via brachiocephalic artery cannulation and circulatory arrest. Twenty-four (75%) of the patients were men. The mean age was 48.69 ± 9.43 years (range, 30-68 yr). Twelve had type I dissection, 2 had type II dissection, and 18 had true aneurysms of the ascending aorta. All operations were performed through a median sternotomy. The arterial cannula was inserted through an 8-mm vascular graft anastomosed to the brachiocephalic artery in an end-to-side fashion. In dissections, the distal anastomosis was performed without clamping the aorta. The patients were cooled to 24 °C, and circulatory arrest was established. The brachiocephalic and left carotid arteries were clamped, and antegrade cerebral perfusion was started at a rate of 10 mL/kg/min. Cardiopulmonary bypass was resumed after completion of the distal anastomosis and the initiation of rewarming. The proximal anastomosis was then performed. None of the patients sustained a major neurologic deficit, but 5 patients experienced transient postoperative agitation (<24 hr). There were 2 early deaths (6.25%), on the 3rd and the 11th postoperative days, both unrelated to the cannulation technique. Brachiocephalic artery cannulation through a graft can be a safe and effective technique in proximal aortic surgical procedures that require circulatory arrest.

Objectives Vascular endothelial dysfunction leads to the emerging of free oxygen radicals, deficiency of antioxidant system, forming of oxidative stress, inflammatory processes and release of proinflammatory cytokines. These things play big role in the development of primary varicose veins. Prolidase has been reported as an indicator of oxidative stress in diabetes, diabetic neuropathy, non-ulcerous dyspepsia, osteoporosis, polycystic over syndrome and many other diseases. The aim of this study is to evaluate the oxidative stress at venous insufficiency and to provide preliminary knowledge about the role of prolidase enzyme in varicose vein formation. Methods Ninety patients aged between 22 and 80 (47.35 ± 17.69) were included in the study and divided into 3 groups. Group1(n:30)(Serum control group): Patients without venous insufficiency. Group 2(n:30)(Tissue control group(healthy vein group): Patients underwent coronary artery bypass surgery (the remaining portion of great saphenous vein used as coronary artery bypass graft used as normal tissue) . Group 3(n:30)(Varicose vein group): Patients underwent varicose vein surgery (varicose vein and serum of these patients were used for study). Total Oxidant Status (TOS), Total Antioxidant Status (TAS), Oxidative Stress Index (OSI) and Prolidase enzyme levels were detected in tissue and serum samples. Results No significant changes were detected between three groups' serum samples in oxidative stress parameters and in the prolidase enzyme activity. The tissue TOS and OSI were higher in varicose vein group according to normal vein group and this was found statistically significant. And TAC levels in varicose vein group were significantly lower than normal vein group. Prolidase enzyme activity in varicose vein group was found higher according to normal vein group. Conclusion Oxidative stress plays a role at the development of primary varicose veins at biochemical level. Prolidase enzyme related with oxidative stress may play an important role in the pathogenesis of primary varicose veins.
