DeepNeXt: a lightweight polyp segmentation algorithm based on multi-scale attention.
Quant Imaging Med Surg
December 2024
Department of Orthopedics, Peking Union Medical College Hospital, Beijing, China.
Background: Fast and accurate automatic segmentation of polyps in colonoscopy plays a crucial role in the early diagnosis and treatment of colon cancer. However, the current polyp segmentation algorithms based on deep neural networks suffer from the problems of larger models and lower segmentation accuracy. Meanwhile, achieving accurate segmentation of polyps is to improve the diagnostic efficiency of doctors, and this need motivates us to develop a set of lightweight models so that it can be easily embedded in clinical devices to meet the requirements of practical applications.

JAMA Netw Open
December 2024
School of Social Work, University of Windsor, Windsor, Ontario, Canada.
Importance: Safer supply programs were implemented in Canada to provide pharmaceutical-grade alternatives to the toxic unregulated drug supply. While research shows clinical benefits and reduced overdose mortality among safer supply patients, medication diversion remains a concern.
Objective: To examine provider (prescribing clinicians and allied health professionals) and patient perspectives on diversion of opioids prescribed in safer supply programs.
A look back at the strike by Mozambican doctors in 2013: what can we learn?
BMC Health Serv Res
November 2024
Global Health and Tropical Medicine, GHTM, LA-REAL, Instituto de Higiene e Medicina Tropical, IHMT, Universidade NOVA de Lisboa, Lisboa, Portugal.
Background: The occurrence of strikes in the health sector has been an increasing concern around the world, given their negative impact on the provision of services and care to patients. The Mozambican doctors' strike in 2013 2013 is considered by many to be the largest of a kind in the country's history, and marked the changes which are still a matter of debate. The aim of this study is to understand the causes, strategies and perceived impact of this strike from the perspective of the main actors involved, taking a look back at everything that happened, including the backstage and tense moments during the negotiations.

RMD Open
November 2024
Rheumatology, ULS de Coimbra EPE, Coimbra, Portugal
Objectives: To evaluate the impact of using Simplified Disease Activity Index (SDAI)-LDA (low disease activity) versus different definitions of remission as a treatment target in established rheumatoid arthritis.
Methods: A meta-epidemiological study of individual patient data from eight randomised controlled trials was performed. Four definitions of the target were considered at 6 months: (1) SDAI-LDA: SDAI≤11; (2) SDAI-Remission: SDAI≤3.
