Objective: Analyze the trends and outcomes of total laryngectomy in Brazil, focusing on the influence of surgical volume on mortality.

Methods: A retrospective, population-based study was conducted using data from the Brazilian Unified Health System (SUS) between 2008 and 2023. Total laryngectomies were identified through specific procedure codes, and hospitals were categorized into quartiles based on surgical volume.

Translation and validation of the Brazilian Portuguese version of the quality of life vascular access device questionnaire for chemotherapy patients.

Background: The use of long-term devices for chemotherapy in neoplastic diseases is very common. The CAVA trial was an extensive study that prospectively evaluated more than 1000 patients undergoing chemotherapy and randomly allocated them to three groups based on the type of catheters used: peripherally inserted central catheters, Port, or Hickmann. For this study, the Quality of Life Vascular Access Device (QoLVAD) questionnaire was administered to assess the impact of these devices (abovementioned catheters) on the patients' daily lives.

Temporal trend in venous thromboembolism hospitalization rates in Brazil.

Objective: Venous thromboembolism is a condition of great interest to public health, as it is potentially preventable and has a high morbidity and mortality potential. Knowing the real-world data in a country of continental dimensions such as Brazil is essential to help define health policies that enable proper diagnosis and treatment of this disease. The objective of this study was to evaluate the incidence and in-hospital mortality rates of venous thromboembolism in public hospitals under Brazil's public health system.

Are changes in physical activity associated with depression? A follow-up study of 1,950 individuals.

Background: This study evaluated the association between changes in physical activity and depression among 1,950 Brazilians. Individuals who increased their physical activity and those who decreased it were not associated with reduced depression. Conversely, being consistently active was identified as an independent and significant protective factor against depression in this population.

Aortic calcium score predicts early outcomes in aortoiliac revascularization.

Background: Calcium scores were evaluated in the lower limbs of patients with clinical limb ischemia after aortoiliac revascularization. The aortic calcium score was related to the short-term outcomes of amputation and subsequent revascularization. Similarly, the calcium score in below-the-knee arteries was associated with revascularization and amputation at 12 months.

Association between the Self-Reported like Engaging in Physical Activity and the Physical Activity Level in Patients with Peripheral Artery Disease.

Background: Patients with symptomatic peripheral artery disease (PAD) face numerous barriers to engaging in physical activity (PA), such as exercise-induced pain, so it is reasonable to hypothesize that these patients do not like engaging in PA. Therefore, this study aimed to analyze the prevalence of self-reported like engaging in PA, as well as whether this factor is associated with higher levels of PA and lower sedentary behavior (SB) in patients with symptomatic PAD.

Methods: This cross-sectional study included 178 patients with symptomatic PAD who were submitted to a question related to self-reported like engaging in PA and a questionnaire related personal and environmental barriers to PA.

Analysis of 19 439 lower limb amputations in children in Brazilian health system over 14 years.

Background: Amputations in children represent significant events. Few studies analyse amputations in this specific population, and most of them are old, regionalised and with small sample sizes. Besides, there are no large studies in low-income and middle-income countries.

Chronic spontaneous non-aneurysmal aortic rupture treated with endovascular surgery.

Spontaneous non-aneurysmal aortic rupture is rare and is usually attributed to penetrating aortic ulcers, infections, tumor infiltrations, or inflammatory and collagen diseases. Chronic rupture is infrequent but extremely rare in non-aneurysmal aortas, which makes diagnosis difficult because the absence of an aneurysm can mislead the physician to rule out rupture. Here, we describe the case of an 85-year-old male, who was undergoing oncological investigation for weight loss, inappetence, and back pain.

Correlation between increased flushing intervals and malfunction and infectious complications in fully implantable catheters during the COVID-19 pandemic.

Objective: To evaluate the incidence of malfunction and colonization rates of fully implantable long-term catheters left unflushed during the COVID-19 pandemic; and to evaluate the average cost of transporting each patient to the hospital for flushing.

Methods: During the COVID-19 pandemic, patients reduced the number of hospital visits and stopped flushing their catheters periodically with saline solution. After the pandemic stabilized in 2022, patients who completed chemotherapy treatment had their long-term catheters removed.

New virtual contrast enhancement boost technique can reduce the dose of intravenous contrast medium used in computer tomography angiography of the abdominal aorta.

Purpose: This study aims to evaluate the image quality of computed tomography (CT) angiograms obtained using a virtual contrast augmentation technique, adding an iodine map to the contrast-enhanced images, obtained through a digital subtraction technique, reducing the dose of intravenous iodinated contrast medium compared to the conventional institutional standard technique.

Methods: This prospective investigation enrolled patients previously diagnosed with abdominal aortic aneurysms, who underwent two successive computed tomography angiographies (CTAs) of the aorta. One CTA was performed employing the virtual contrast enhancement boost technique with a 40% decrease in the intravenous contrast medium dose, while the other adhered to the conventional protocol without any reduction in contrast medium volume.

Robotic cardiac surgery for removal of iliac venous stent embolized in the right cardiac chambers: a case report.

A 42-year-old female patient with a surgical history of iliac venous angioplasty with stenting developed dyspnea on exertion 9 months later. Chest computed tomography angiography revealed a fractured vascular stent in the right cardiac chamber. Doppler echocardiography confirmed that the stent was anchored by the tricuspid valve, causing mild obstruction of the right ventricular filling.

Biomechanical and histological analyses of a multilayer stent in a swine model of suprarenal aortic aneurysm.

Objectives: To analyze and compare, in an animal model, the treatment of thoracoabdominal aneurysms with multilayer stents and its hemodynamic effects through the biomechanical and histological analysis of the aortic wall in contact with the stent.

Methods: Large White pigs were randomized into two groups: Stent (n=6) and Control (n=5, non-stent). All animals were subjected to the creation of a suprarenal aneurysm with a bovine pericardial patch.

Walking training decreases cardiovascular load after walking to maximal intermittent claudication in patients with peripheral artery disease.

Purpose: This study investigated whether: 1) walking training (WT) changes cardiovascular load after walking until maximal intermittent claudication (IC) in patients with peripheral artery disease (PAD); and 2) acute and chronic cardiovascular responses to walking were related to each other.

Methods: A randomized, controlled, parallel-group design was employed. Thirty-two men with PAD and IC were randomly assigned to one of two groups: WT (n=16) or control (CO, n=16) twice a week for 12 weeks.

Association between physical activity performed at different intensities and cardiovascular health in patients with peripheral artery disease: an observational study.

Background: We examined the sedentary behavior and physical activity of 260 patients with peripheral artery disease. Women engaged in more light physical activity than men did. Light physical activity was associated with lower arterial stiffness in men only, while no significant associations were found between sedentary behavior, moderate-vigorous physical activity, and cardiovascular outcomes.
