Purpose: To compare robotic versus laparoscopic colectomies in colon cancer patients in general complications.

Methods: Nine databases were searched for randomized controlled trials (RCT) investigating patients with colon cancer, submitted to robotic surgery (RS) compared to a laparoscopic (LC) approach. The risk of bias was assessed using RoB 2.

Dementia has been faced with significant public health challenges and economic burdens that urges the need to develop safe and effective interventions. In recent years, an increasing number of studies have focused on the relationship between dementia and liver and pancreatic metabolic disorders that result in diseases such as diabetes, obesity, hypertension and dyslipidemia. Previous reports have shown that there is a plausible correlation between pathologies caused by hepatopancreatic dysfunctions and dementia.

With the advancement of in vivo studies and clinical trials, the pathogenesis of neurodegenerative diseases has been better understood. However, gaps still need to be better elucidated, which justifies the publication of reviews that explore the mechanisms related to the development of these diseases. Studies show that vitamin E supplementation can protect neurons from the damage caused by oxidative stress, with a positive impact on the prevention and progression of neurodegenerative diseases.

Introduction: Neurodegenerative diseases are characterized by neuronal dysfunction and death. Studies suggest that some seed extracts have a neuroprotective effect. Considering the increased incidence of these diseases and the need for new effective therapies with fewer side effects, this review aimed to assess the evidence of the efficacy and safety of seed extracts in experimental models of neurodegeneration.

Introduction: Up to the present time, the laparoscopic approach for colon cancer is considered the gold standard. However, robotic surgery has been appraised in modern medicine. It is essential to evaluate the differences between laparoscopic and robotic surgery, owing to the significant impact they cause in postoperative morbidity and mortality.

Background: The use of electronic cigarettes is one of the current public health problems on increasing alert, has been growing at an accelerating rate, and has become a public health emergency. Its importance is explained by the continuous growth and acceleration of oncological rates among all ages versus the absence of high-quality evidence, correlated to the use of nicotine derived products, being at their regular versions or the new ones. Available preclinical data indicate that activation of the sympathetic nervous system by nicotine inhaled from e-cigarettes may stimulate cancer development and growth by several mechanisms, which results can significantly reduce life's quality.

The use of mobile phones has dramatically increased all over the world. Such revolution in the communication amongst individuals has a great impact in patient care, supporting their self-management and promoting shared responsibility with health services. Given that improved communication facilitates compliance with scheduled procedures and reduces surgical cancellations, the current work aims to develop a communication tool named Surgery Remember@ to mitigate surgical suspensions due to patient absenteeism.

Background And Objective: The growth of the urban population exerts considerable pressure on municipalities' public managers to focus their attention on providing emergency medical care that meets the growing demand for emergency pre-hospital medical care. Currently, there are a significant number of traffic accidents and other serious occurrences, such as heart attacks, drownings, epidemics, fires and disasters (floods, landslides, earthquakes) that demand a prompt and seamless response from pre-hospital medical care. As a result of such scenario, the present article endeavours to apply a dual-coverage mathematical model (DSM-Double Standard Model) to define the optimal location of the Emergency Medical Service (SAMU) decentralized dispatch bases in Natal/RN and conduct a simulation study to evaluate the displacement of ambulances between such bases.

Article Synopsis
  • Extracellular vesicles (EVs) from stem/stromal cells offer a promising, cell-free method in regenerative medicine that could enhance tissue healing, particularly for difficult conditions like post-surgical colo-cutaneous fistulas.
  • The study assessed the effectiveness of SC EVs delivered in a thermoresponsive hydrogel in a rat model of intestinal fistulas, showing that this approach can reduce fistula size, output, fibrosis, and inflammation.
  • The research utilized advanced imaging techniques to confirm that the local administration of SC EVs has significant therapeutic benefits, highlighting a minimally-invasive solution for managing challenging post-surgical conditions.

The growth of the urban population raises concern about municipal public managers in the sense of providing emergency medical services (EMS) that are aligned with the needs of prehospital emergency medical care demanded by the population. The literature review aims at presenting the response time of emergency medical services in several parts of the world and discussing some factors that interfere in the result of this indicator such as GDP (Gross Domestic Product) percentage spent on health and life expectancy of countries. The study will also show that in some of the consulted articles, authors suggest to EMS recommendations for decreasing the response time using simulations, heuristics and metaheuristics.

Nature has always provided an unlimited source of biologically-active compounds. Since the beginning of mankind, humans have sought resources in fauna and flora to treat eye diseases. However, it was only after the Industrial Revolution that extracts of plants and substances of animal origin could be used safely, as has been determined by controlled interventional studies.

Background: Neurological disorders constitute a growing worldwide concern due to the progressive aging of the population and the risky behavior they represent. Herbal medicines have scientific relevance in the treatment of these pathologies. One of these substances, Astragaloside IV (AS-IV), is the main active compound present in the root of Astragalus membranaceus (Fisch.

Background: The formation of senile plaques and neurofibrillary tangles of the tau protein are the main pathological mechanism of Alzheimer's disease (AD). Current therapies for AD offer discrete benefits to the clinical symptoms and do not prevent the continuing degeneration of neuronal cells. Therefore, novel therapeutic strategies have long been investigated, where curcumin (Curcuma longa) has shown some properties that can prevent the deleterious processes involved in neurodegenerative diseases.

Parkinson's disease (PD) consists of a neurodegenerative pathology that has received a considerable amount of attention because of its clinical manifestations. The most common treatment consists of administering the drugs levodopa and biperiden, which reduce the effectiveness of the disease and the progress of its symptoms. However, phytotherapy treatment of PD has shown great potential in retarding the loss of dopaminergic neurons and minimizing the behavioral abnormalities.
