Occupational risks associated with chronic kidney disease of non-traditional origin (CKDnt) in Brazil: it is time to dig deeper into a neglected problem.

In the past decades, an epidemic of chronic kidney disease (CKD) has been associated with environmental and occupational factors (heat stress from high workloads in hot temperatures and exposure to chemicals, such as pesticides and metals), which has been termed CKD of non-traditional origin (CKDnt). This descriptive review aims to present recent evidence about heat stress, pesticides, and metals as possible causes of CKDnt and provide an overview of the related Brazilian regulation, enforcement, and health surveillance strategies. Brazilian workers are commonly exposed to extreme heat conditions and other CKDnt risk factors, including increasing exposure to pesticides and metals.

Ultraprocessed foods and chronic kidney disease-double trouble.

High energy intake combined with low physical activity generates positive energy balance, which, when maintained, favours obesity, a highly prevalent morbidity linked to development of non-communicable chronic diseases, including chronic kidney disease (CKD). Among many factors contributing to disproportionately high energy intakes, and thereby to the obesity epidemic, the type and degree of food processing play an important role. Ultraprocessed foods (UPFs) are industrialized and quite often high-energy-dense products with added sugar, salt, unhealthy fats and food additives formulated to be palatable or hyperpalatable.

COVID-19 and Nutrition: Focus on Chronic Kidney Disease.

Some chronic diseases, including chronic kidney disease (CKD), may be associated with poor outcomes, including a high rate of hospitalization and death after COVID-19 infection. In addition to the vaccination program, diet intervention is essential for boosting immunity and preventing complications. A healthy diet containing bioactive compounds may help mitigate inflammatory responses and oxidative stress caused by COVID-19.

Demographic and occupational profile of dietitians working in dialysis centers in Brazil.

Introduction: In 2004, the Ministry of Health stipulated that dialysis centers were required to have at least one dietitian on their staff. However, the regulation did not include recommendations regarding the number of dietitians or the workload based on the number of patients assisted.

Objective: To describe the demographic and occupational profiles of dietitians working in dialysis centers in Brazil.

Hemodialysis in Brazil: differences across geographic regions regarding demographics, laboratory parameters and drug prescription.

Introduction: Brazil has a vast territory divided into five geographic regions with important differences in sociodemographic indices.
