Background Characterizing the post-COVID health conditions is helpful to direct patients to appropriate healthcare. Aims To describe the presence of symptoms in COVID-19 patients within 6 months after diagnosis and to investigate the associated factors in terms of reporting symptoms. Methods Data of DEU-COVIMER (a telephone interview-based COVID-19 follow-up center established in a tertiary care hospital) was analyzed for SARS-CoV-2 RNA positive participants aged ≥ 18 years from November 1st, 2020, to May 31st, 2021. Symptom frequencies were stratified by demographic and clinical characteristics at one, three, and 6 months after diagnosis. With the patients who had symptoms at baseline, generalized estimating equations were applied to identify the factors associated with reporting of symptoms. Results A total of 5610 patients agreed to participate in the study. Symptom frequency was 37.2%, 21.8%, and 18.2% for the first, third, and sixth months. Tiredness/fatigue, muscle or body aches, and dyspnea/difficulty breathing were the most common symptoms in all time frames. In multivariate analysis, older age, female gender (odds ratio OR 1.74, 95% confidence interval 1.57–1.93), bad economic status (OR 1.37, 1.14–1.65), current smoking (OR 1.15, 1.02–1.29), being fully vaccinated before COVID-19 (OR 0.53, 0.40–0.72), having more health conditions (≥ 3 conditions, OR 1.78, 1.33–2.37), having more symptoms (> 5 symptoms, OR 2.47, 2.19–2.78), and hospitalization (intensive care unit, OR 2.18, 1.51–3.14) were associated with reporting of symptoms. Conclusions This study identifies risk factors for patients who experience post-COVID-19 symptoms. Healthcare providers should appropriately allocate resources prioritizing the patients who would benefit from post-COVID rehabilitation.

Hybrid procedures could be performed safely with lower complication and higher success rates in the same session via antegrade route and zone 0 graft deployment for high-risk cases with isolated or nonisolated aortic arch aneurysms.

Objective Cisplatin (CDDP) toxicity is a dose-limiting clinical problem in clinical practice, mainly because of nephrotoxicity or ototoxicity. However, the mechanism of CDDP-induced cardiotoxicity is poorly understood. Acetyl-l-carnitine (ALCAR) is an antioxidant agent with protective effects against the side effects of various chemotherapeutics. CDDP-induced cardiotoxicity and the protective role of ALCAR were evaluated in this study. Methods Morphological changes were evaluated in hematoxylin and eosin-stained sections, and immunohistochemistry for caspase-3, superoxide dismutase-2 (SOD-2), inducible nitrite oxide synthase (iNOS), cyclooxygenase-2, and Bcl-2 was performed using the hearts of athymic nude mice carrying xenograft neuroblastoma tumors. Mice were randomized (six/group) to the control, CDDP (16 mg/kg), and ALCAR (200 mg/kg)+CDDP (16 mg/kg) groups. Results were analyzed using nonparametric tests. Results No difference was observed in the rates of cardiac necrosis, dilated/congested blood vessels, hemorrhage, polymorphonuclear leukocyte infiltration, edema, and pyknotic nuclei among the groups. SOD-2 expression was increased in the CDDP group but not in the ALCAR+CDDP group. iNOS, Bcl-2, and caspase-3 levels were not significantly different among the groups. Conclusions ALCAR might be a candidate protective agent for CDDP-induced cardiotoxicity. SOD-2, as a member of the oxidant system, should be evaluated in further studies as a biomarker of cardiotoxicity.

In suitable patient groups, the IOBH technique could be safely performed by experienced centers.

was first seen in China in December 2019. Covid-19 turned into a pandemic in a very short time. Thanks to the strong precautions taken, it appeared in our country at a very late date according to our geographical location. With the announcement of the pandemic of the World Health Organization, administrative and medical evaluations were carried out at the Dokuz Eylül University Health Campus, guided by the algorithms developed by the Ministry of Health. And the process continued with these principles. In the study, the evaluation processes and socio-demographic characteristics of patients admitted to the Dokuz Eylül University Pandemic Outpatient Clinic were examined. In the long term, predictions about whether mass isolation is sustainable and how the normalization process should be continued are also included. For this purpose, the demographic characteristics of the patients who were followed up in the DEU Research and Application Hospital with the diagnosis of Covid-19 during the period of 18.03.2020-24.04.2020 were taken into consideration. The Covid-19 pandemic process we are experiencing reveals that one of the basic needs of a society is health services. In addition, the exact rate of Covid-19 cases contacting other Covid-19 cases is high. Therefore, it is very important to provide social isolation to control the spread of the pandemic. However, taking necessary measures in the public and private sectors and moving to a controlled normalization process is of great importance.

IntroductionA common problem encountered in routine daily practice of cardiovascular surgery is migration of smooth muscle cells leading to intimal hyperplasia developing at vascular anastomosis sites which then causes luminal narrowing. The aim of this study was to investigate the antiproliferative effect of 1,25 (OH)2D3 on intimal hyperplasia.Material and methodsTwenty-one male white New Zealand rabbits weighing 2-3 kg were selected. There were 3 groups of animals each consisting of 7 rabbits. Group 1 was the control group. Group 2 was the sham group and group 3 consisted of rabbits receiving 1,25 (OH)2D3. The right carotid arteries of the subjects in groups 2 and 3 were transected and re-anastomosed. A daily dose of 25 ng 1,25 (OH)2D3 per 100 g body weight was administered for 14 days to rabbits in group 3. Rabbits in group 2 were not subject to any pharmaceutical agent. All the subjects were sacrificed at the end of the 28th postoperative day. Their right carotid arteries were resected and then investigated histopathologically.ResultsIntimal thickness and intimal area were measured as significantly lower in group 1 when compared with the other groups (p = 0.004). In group 3, the ratios of thickness of tunica intima/thickness of tunica media and area of tunica intima/area of tunica media were significantly lower than those of group 2 (p = 0.015, p = 0.003).Conclusions1,25 (OH)2D3, the active metabolite of vitamin D, reduces the intimal hyperplasia developing after vascular anastomoses.
