OBJECTIVE This study established the incidence and primary causes of unplanned extubation in newborns in the neonatal intensive care units of the Hospital Sofia Feldman, Belo Horizonte (Minas Gerais). METHODS This retrospective study was conducted between July 1, 2009 and April 30, 2010. Unplanned extubations and their primary causes were assessed using an adverse events form. The following v...
INTRODUCTION There have been no prospective randomized trials that enable the best strategy and timing to be determined for revascularization in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and multivessel coronary artery disease (CAD). OBJECTIVES To compare short- and long-term adverse events following multivessel vs. culprit-only revascularization in patients wi...
The stability graph method for open stope design is one of the most widely used approaches predicting stopes in underground metalliferous mines. primary purpose this work to propose a new chart, which includes all relevant case histories, and exclude parameters with uncertainties determining number. modified number was achieve goal, Extended Mathews database recalculated compared graph. In stud...
Precise quantification of plant nitrogen (N) nutrition status is essential for crop N management. The concept of critical N concentration (Nc) has been widely used for assessment of plant N status. This study aimed to develop a new winter wheat Nc dilution curve based on leaf area duration (LAD). Four field experiments were performed on different cultivars with different N fertilization modes i...
Background: Despite the progress of family planning programs, a significant proportion of pregnancies are still unplanned which threatens the different dimensions of community health. Unplanned pregnancy affects parent's-child association. Maternal-fetal attachment provides a model for the child's mental-social function at present and in the future. Objectives: This study was conducted to dete...
BACKGROUND We aimed to describe the clinical characteristics and outcomes of unplanned excisions of synovial sarcomas. METHODS In total, 90 patients with synovial sarcomas in the extremities were retrospectively reviewed. Patients were divided into unplanned excision (n = 38) and planned excision (n = 52) groups. The average follow-up period was 6 years. The clinicopathological characteristic...
OBJECTIVES Access to reproductive healthcare, including contraceptive services, is an essential component of comprehensive healthcare for female sex workers (FSW). Here, we evaluated the prevalence of and factors associated with contraceptive use, unplanned pregnancy, and pregnancy termination among FSW in three transit towns in Zambia. STUDY DESIGN Data arose from the baseline quantitative s...
Patient discharge from the ICU is indicated on the basis of clinical evidence and the result of strategies aimed at improving health care. Nevertheless, some patients might be discharged too early. We attempted to identify risk factors for unplanned ICU readmission, using a score for risk assessment, designated the Stability and Workload Index for Transfer (SWIFT) score. We evaluated 100 patien...
A gully is an excavation cut in the immediate footwall or hangingwall of the reef for the purpose of enabling the removal of rock from the face or providing access to the face for mining personnel or material1. The gully sidewalls and hangingwall often pose a serious stability problem in the gold and platinum mines in South Africa, since records of fatal rock-related injuries show that they are...
This study examines the effect of the booth Recommender system (BRS) embedded in a mobile device on the goals of exhibition attendees, based on two main theories that are unplanned behaviour and goal frame theories. Previous studies have overlooked the importance of the unplanned behavioural effectiveness of IT devices for understanding motivation and delivering unexpected outcomes at exhibitio...
