Background: Diabetes mellitus increases the risk of ischaemic stroke in the general population but its impact on early outcome after the carotid endarterectomy (CEA) is controversial with conflicting results. Patients and methods: This prospective study includes 902 consecutive CEAs. Patients were divided into non-diabetic and diabetic groups and subsequently analysed. Early outcomes in terms of 30-day stroke and death rates were then analysed and compared. Results: There were 606 non-diabetic patients. Among 296 diabetic patients, 83 were insulin-dependent. The cumulative TIA/stroke rate was statistically higher in the diabetic group (2.6 vs. 5.7 %, P = 0.02). Stroke was more frequent in the diabetic group (2.0 vs. 4.4 %, P = 0.04) comparedto TIA (0.7 vs. 1.4 %, P = 0.45). Mortality was statistically more frequent in diabetic patients (0.2 vs. 1.7 %, P = 0.01). The 30-day stroke/death rate (2.6 vs. 5.7 %, P = 0.02) was also statistically higher in the diabetic group. Factors that were identified to increase risk of death and stroke in multivariate analysis were: use of insulin for blood glucose control (OR = 2.47, 95 % CI 1.61–4.68, P = 0.01), higher low-density lipoprotein cholesterol value (OR = 1.52, 95 % CI 1.15–2.22, P < 0.01), presence of coronary disease (OR = 2.04, 95 % CI 1.40–3.31, P = 0.03), peripheral artery disease (OR = 2.14, 95 % CI 1.34–3.65, P = 0.02), complicated plaque (OR = 1.77, 95 % CI 1.11–3.68, P = 0.03), contralateral carotid artery occlusion (OR = 2.37, 95 % CI 1.25–4.74, P = 0.02), shunt use (OR = 3.46, 95 % CI 1.18–7.10, P < 0.01), and among diabetic patients higher HbA1c levels (OR = 1.28, 95 % CI 1.05–1.66, P = 0.03). Clamp toleration was associated with lower risk of death and stroke rates (OR = 0.43, 95 % CI 0.23–0.76, P < 0.01). Conclusions: In our study, perioperative neurological complications and mortality were statistically higher in diabetic patients compared to non-diabetic patients during CEA. Further research will have to show whether other treatment modalities of carotid artery stenosis and better glycaemia and dyslipidaemia controlling in diabetics can reduce this risk. © 2018 Hogrefe.

Metabolic syndrome (MetS) is a leading public health and clinical challenge worldwide. MetS represents a group of interrelated risk factors that predict cardiovascular diseases (CVD) and diabetes mellitus (DM). Its prevalence ranges between 10 and 84%, depending on the geographic region, urban or rural environment, individual demographic characteristics of the population studied (sex, age, racial and ethnic origin), as well as the criteria used to define MetS. Persons with MetS have higher mortality rate when compared with people without MetS, primarily caused by progressive atherosclerosis, accelerated by pro-inflammatory and pro-coagulation components of MetS. Considering the high prevalence of metabolic disorders (glucose metabolism disorder, hypertension, dyslipidaemia, obesity etc.), preventive healthcare should focus on changing lifestyle in order to reduce obesity and increase physical activity. This narrative review considers the available evidence from clinical and experimental studies dealing with MetS, and current treatment options for patients with insulin resistance and MetS. © 2017 Bentham Science Publishers.

BACKGROUND: We aimed to further evaluate sex differences of perioperative and 30-day complications after carotid surgery in patients with both asymptomatic and symptomatic carotid artery stenosis. METHODS: This was a single-center prospective cohort study including 2013 consecutive patients, who were treated surgically due to extracranial carotid artery stenosis and prospectively followed. Patients who underwent carotid artery stenting and who were treated conservatively were excluded. The primary endpoints for this study were hospital stroke/transitory ischemic attack (TIA) and overall survival rates. Secondary outcomes included all other hospital adverse events, 30-day stroke/TIA, and 30-day mortality rates. RESULTS: Hospital mortality was higher in female patients with symptomatic carotid stenosis (3% vs. 0.5%, P=0.018). Bleeding requiring reintervention occurred more often in female patients with both asymptomatic (1.5% vs. 0.4%, P=0.045) and symptomatic carotid stenosis (2.4% vs. 0.2%, P=0.022). 30-day stroke/TIA and mortality rates were higher in female patients with both asymptomatic (stroke/TIA 4.4% vs. 2.5%, P=0.041; mortality 3.3% vs. 1.6%, P=0.046) and symptomatic carotid stenosis (stroke/TIA 8.3% vs. 4.2%, P=0.040; mortality 4.1% vs. 0.7%, P=0.006). After adjusting for all confounding factors, female gender remained an important predicting factor for 30-day stroke/TIA in asymptomatic (OR=1.4, 95%CI 1.0-4.7, P=0.041) and symptomatic patients (OR=1.7, 95%CI 1.1-5.3, P=0.040), as well as for 30-day all-cause mortality in patients with asymptomatic (OR=1.5, 95%CI 1.1-4.1, P=0.030) and symptomatic carotid artery disease (OR=1.2, 95%CI 1.0-5.2, P=0.048). CONCLUSIONS: Female gender is important predicting factor for stroke/TIA and all-cause mortality, both perioperative and during the first 30 days after carotid surgery. © 2023 EDIZIONI MINERVA MEDICA.

Advanced renal cell carcinoma accompanied by tumor thrombus in the venous system is present in up to 10% of cases. Extension of tumor thrombus above the diaphragm or into the right atrium represents level IV disease. Level IV tumors are typically treated with sterno-laparotomy approach with or without deep hypothermic circulatory arrest and veno-venous bypass. In this case report, the surgical technique for the resection of advanced RCC were described, with the concomitant use of transesophageal echocardiography for thrombus extraction without the veno-venous or cardiopulmonary bypass. © 2019, Sociedade Brasileira de Cirurgia Cardiovascular.
