2024 Standardization of Polysomnography Reports - A Consensus of the Brazilian Sleep Association.
Sleep Sci
December 2024
Departamento de Department, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.
The absence of standardized reporting for sleep medicine exams across different laboratories can lead to misinterpretation, diagnostic inconsistencies, and suboptimal treatment strategies. This document seeks to establish guidelines for the development of sleep study reports, covering recordings from studies of types 1 to 4, and represents the official position of Associação Brasileira do Sono (ABS; Brazilian Sleep Association) on the standardization of polysomnography (PSG) and cardiorespiratory polygraphies. The recommendations for the items to be reported in PSG records were developed by means of a Delphi study, comprised of two voting rounds.

The current document represents the official position of Associação Brasileira do Sono (ABS; Brazilian Sleep Association) on the application of different sleep studies and provides specific recommendations for the use of different types of polysomnography (PSG) and respiratory polygraphy. The present document was based on existing guidelines. The steering committee discussed its findings and developed recommendations and contraindications, which were refined in discussions with the advisory committee.

Article Synopsis
- Oliguria, a condition characterized by decreased urine output, may be misinterpreted as acute kidney injury (AKI) in patients post-surgery, despite being a potential adaptive response during surgery.
- A study analyzing 1,476 patients revealed that 34.4% exhibited oliguria within the first 24 hours after surgery, with certain factors like vasopressor use and non-elective procedures linked to increased risk.
- Although oliguria was associated with a higher rate of AKI development compared to non-oliguric patients, 87.6% of oliguric patients did not show kidney dysfunction based on serum creatinine levels, questioning the accuracy of oliguria as an indicator for AKI.
Key Performance Indicators of Secondary Health Care in Chronic Kidney Disease: Experience in Public and Private Services in the State of São Paulo, Brazil.
Int J Nephrol
October 2024
Nephrology Division, Federal University of São Paulo, São Paulo 04023-062, Brazil.
Article Synopsis
- The study aimed to assess the quality of secondary health care for chronic kidney disease (CKD) patients in Brazil, comparing the Brazilian Unified Health System (UHS) to a private health plan (PHP).
- UHS patients were older, had higher rates of arterial hypertension and dyslipidemia, but worse kidney function and fewer optimal health indicators compared to PHP patients.
- The findings suggest that UHS patients experienced faster CKD progression and poorer overall care quality, highlighting the potential benefits of multidisciplinary approaches for improving patient outcomes.
Short and long-term effects of kidney donation on mineral and bone metabolism.
BMC Nephrol
October 2024
Nephrology Division, Laboratório de Fisiopatologia Renal (LIM16) - Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP), São Paulo, Brazil.
Background: Living kidney donors (LKD) experience an abrupt decline in glomerular filtration rate (GFR) resulting in abnormalities of mineral and bone metabolism (MBD), and this may have implications for skeletal health. We prospectively studied acute and long term MBD adaptation of LKD from two kidney transplant centers (São Paulo, Brazil and Miami, USA).
Methods: Renal function and MBD parameters longitudinally after kidney donation (baseline - D0, day 1, 14, 180 and 360 post-operatively) were measured in 74 patients (40 y, 73% female, 54% Brazilian).
