Introduction: The annual Brazilian Dialysis Survey (BDS) supports and contributes to the development of national health policies. Objective: To report the 2023 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN).

Methods: A survey was carried out in a voluntary sample of Brazilian chronic dialysis centers using an online questionnaire covering clinical and epidemiological aspects of patients on chronic dialysis, and characteristics of dialysis centers.

Tracking Boats on Amazon Rivers-A Case Study with the LoRa/LoRaWAN.

The Amazon region has the largest hydrographic basin in the world. The rivers act as roads, and boats serve as vehicles for transporting passengers and cargo to large urban centers, municipalities, riverside communities, villages, and settlements. The Amazon River transportation system faces critical gaps due to the lack of land infrastructure in certain areas, which makes rivers essential for commerce and access to isolated communities.

Continuous colonization of the Atlantic coastal rain forests of South America from Amazônia.

The two main extensions of rain forest in South America are the Amazon (Amazônia) and the Atlantic rain forest (Mata Atlântica), which are separated by a wide 'dry diagonal' of seasonal vegetation. We used the species-rich tree genus to test if Amazônia-Mata Atlântica dispersals have been clustered during specific time periods corresponding to past, humid climates. We performed hybrid capture DNA sequencing of 810 nuclear loci for 453 accessions representing 164 species that included 62% of Mata Atlântica species and estimated a dated phylogeny for all accessions using maximum likelihood, and a species-level tree using coalescent methods.

The use of topical antiseptic solutions in the healing process of post-surgical skin wounds in dogs (Canis lupus familiaris).

Purpose: To evaluate whether the effectiveness of topical antiseptic solutions in restoring skin continuity solutions is related to their antimicrobial action or to their action in maintaining moisture, in dogs undergoing elective surgeries.

Methods: Forty dogs, 20 males and 20 females, underwent orchiectomy and oophorectomy, respectively. Thereafter, the animals were allocated into four groups (n = 5) and treated with different topical solutions: polyhexanide 0.

Extraction and Characterization of Inulin-Like Fructans from Hydroponically Grown Stevia rebaudiana Roots for Food Applications.

Stevia rebaudiana is a plant native to South America known for producing steviol glycosides and fructans used in low-calorie and functional foods. This study aimed to cultivate and isolate inulin from hydroponically grown S. rebaudiana roots.
