Mortality due to malignant neoplasms of the liver and intrahepatic biliary tract in the state of Mato Grosso in 2020

Malignant neoplasms of the liver and intrahepatic biliary tract occupy the third place of cancer deaths in the world and the second most deadly in men and the sixth in women. Eating habits characterized by the consumption of food with high caloric and glycemic indexes, associated with a sedentary lifestyle, provide a greater risk of developing hepatic steatosis, as well as obesity, which, together with the increased incidence of chronic viral hepatitis, excessive alcoholism, and age over 50 years, constitute the main risk factors for the development of these types of cancer. In addition, due to the chronicity of liver pathologies, the diagnosis is usually late, a factor that contributes to increase the mortality rate. Thus, the objective of this work is to analyze the epidemiological profile of deaths due to liver cancer and intrahepatic biliary tract that occurred in the state of Mato Grosso in 2020. This is a cross-sectional study based on data from the Mortality Information System (SIM), made available by the Department of Informatics of the Unified Health System (DATASUS), and in the population estimate of the Brazilian Institute of Geography and Statistics (IBGE) for 2020. A study was carried out of the epidemiological profile of deaths related to liver and intrahepatic biliary ducts neoplasms (CID 10 C-22) of the state of Mato Grosso for the year 2020 regarding age group, sex (gender), and race. A total of 120 deaths due to malignant neoplasms of the liver and intrahepatic biliary tract were reported, corresponding to a mortality rate of approximately 3.4 deaths/100,000 inhabitants, with the proportion of deaths between men and women approximately 4:3. For both sexes, there is an abrupt increase in the incidence of deaths after the sixth decade of life, corresponding to 90% of deaths due to this pathology. Regarding the racial evaluation, deaths are more incident in the yellow race, with about 4.97 deaths/100,000 inhabitants, followed by the black race with 4.87 deaths/100,000 inhabitants. Thus, it is evident that deaths from liver and intrahepatic biliary tract malignant neoplasms in the state of Mato Grosso, in 2020, were concentrated from the sixth decade of life, especially in men, with emphasis on the yellow race. It should be noted that the analysis of epidemiological characteristics is essential for the development of screening policies and early diagnosis in patients with modifiable and non-modifiable risk factors

Prevalence and influence of overweight and obesity on clinical and epidemiological profile of breast cancer patients in the North of Mato Grosso, Brazil: a retrospective cross-sectional study

Obesity is one of the main preventable risk factors in post-menopausal breast cancer. This retrospective cross-sectional study aimed to demonstrate the clinical and epidemiological profile of breast cancer patients diagnosed in the period from 2013 to 2018 in the North of Mato Grosso, Brazil and to verify the prevalence and influence of overweight and obesity in these patients. Data were collected from patient’s medical records who were diagnosed with breast carcinoma in the Department of Oncology of Santo Antônio’s Hospital, in Sinop-MT. 196 patients were included. 99.5% were women. The majority were married, ≥50 years old (57.7%) and overweight or obese. In the overweight and obesity group the percentage of patients with invasive breast carcinoma were significantly higher when compared with eutrophic group (p=0.03). In all groups the profile of estrogen and progesterone receptors positive and HER-2 negative were more prevalent, however, the frequency of triple negative profile was higher in the overweight (7.1%) and obesity (6.3%) group when compared with control (4.3%) group, as well as the presence of hypertension and diabetes. In conclusion, it was observed a high prevalence of overweight and obesity in breast cancer patients, which contributed to modify the histological type of breast cancer (high prevalence of invasive and lobular carcinomas), increase the frequency of patients in stages 3 and 4, the percentage of triple negative profile and the frequency of other comorbidities, as hypertension and diabetes. Furthermore, metformin, an antidiabetic drug, seems to be contributing to reduce tumor development and improve the clinical profile and prognosis in diabetic breast cancer patients

A wearable chatbot-based model for monitoring colorectal cancer patients in the active phase of treatment

Colorectal cancer is one of the leading causes of death in the world. This study presents the findings of a prospective non-randomized clinical study for evaluating a new computational model for monitoring colorectal cancer patients in the active treatment phase using artificial intelligence and the Internet of Things. For eight weeks, patients self-reported perceived symptoms and adverse effects, practiced physical activity, and data about their diet. The outcome assessment was based on comparing the intervention and control groups. Patients evaluated the model using the User Experience Questionnaire (UEQ) and the System Usability Scale (SUS). Patients who participated in the model reported signs and symptoms more accurately (control: 64.7%; intervention: 92.3%; p = 0.1038). In the intervention group, physical activity was more effective, and most patients (61.5%) interacted with the chatbot for at least 62.5% of the period. Results indicate that the model contributes to more assertive data collection and greater patient engagement in self-management of symptoms and adverse effects of treatment and cancer. Moreover, the model contributed to increasing the practice of light physical activity by patients. UEQ and SUS scores indicate that the model met users’ expectations and has acceptable usability
