OBJECTIVE to verify the correlation between the rates of hospitalization for primary care-sensitive cardiovascular diseases and the coverage by the Family Health Strategy of residents of the State of Paraná, by regional health divisions, from 2000 to 2011. METHOD ecological study developed from data of the Hospital Information System of the Brazilian Unified Health System (SUS) and the Depart...

background a high proportion of patients suffering from end stage liver disease are from low socioeconomic classes , which limits their access to liver transplantation as the most effctive treatment of this condition because of cost barrier. objectives one of the most challenging aspects of liver transplantation is its affordability and utilization by those who need it the most. patients and me...

This paper presents a new and efficient method based on evolutionary algorithms to address the multi-stage (dynamic) planning of open loop structured distribution networks under uncertainty taking into account distributed generation connected to distribution system. The proposed model can cope with important features implicit in planning studies such as time-phased representation and uncertaint...

Abstract The mathematical model can be widely applied to the field of deployment and topology control in wireless sensor networks. In wireless sensor networks, sensor nodes are randomly distributed of highdensity. How can we use a minimum number of sensor nodes achieving requirement of coverage and connectivity is a NP-hard problem. This paper formulates a mathematical model in which only if so...

Commonsense reasoning, in particular qualitative spatial and temporal reasoning (QSTR), provides flexible and intuitive methods for reasoning about vague and uncertain information including temporal duration and ordering, and spatial orientation, topology and distance. Despite significant theoretical advances in QSTR, there is a distinct absence of applications that employ these methods. The ce...

BACKGROUND AND PURPOSE Acetabular retroversion may result in anterior acetabular over-coverage and posterior deficiency. It is unclear how standard radiographic measures of retroversion relate to measurements from 3D models, generated from volumetric CT data. We sought to: (1) compare 2D radiographic measurements between patients with acetabular retroversion and normal control subjects, (2) com...

This paper defines the concept of regional e-commerce by analyzing the literature. According to the definition, this paper extracted the core indicators of regional e-commerce development, and used the principal component analysis to evaluate the development level of regional e-commerce. Finally, this paper analyzes the impact factors of regional e-commerce development from qualitative and quan...

BACKGROUND Trachoma is the leading infectious cause of blindness worldwide. In communities where the district level prevalence of trachomatous inflammation-follicular among children ages 1-9 years is ≥5%, WHO recommends annual mass drug administration (MDA) of antibiotics with the aim of at least 80% coverage. Population-based post-MDA coverage surveys are essential to understand the effectiven...

Fractures of the proximal upper extremity present a challenge to the anesthesia provider when administering a regional anesthetic because the dermatomal distribution of the upper extremity requires more local anesthetic coverage than any single brachial plexus nerve block can provide. A 60-year-old woman underwent intramedullary nailing of a pathologic humeral fracture using a combination of re...
