in july 2003, the bellagio study group on child survival estimated that the lives of 6 million children could be saved each year if 23 proven interventions were universally available in the 42 countries re-sponsible for 90% of child deaths in 2000. the aim of this study was to determine frequency of important causes of mortality among under-5 year old children in hospitals, tehran, iran. inform...

hospital information system (his) should ideally allow different forms of data to be stored and used for decision making by clinicians and managers alike. this system has been developed since the early 1980's, and many hospitals gradually converted from an unrelated system into an integrated one. in successful implementation of his plans, the role of human factors, either individually or as a g...

While extended infusions of piperacillin-tazobactam (TZP) are increasingly used in practice, the effect of infusion on the pharmacokinetic (PK) profile of TZP has not been widely assessed. To assess its effect on the pharmacokinetic profile of TZP, seven serum samples were collected from 11 hospitalized patients who received 3.375 g TZP intravenously for 4 h every 8 h. Population pharmacokineti...

Carbapenems are a class of last-resort antibiotics; thus, the increase in bacterial carbapenem-resistance is a serious public health threat. Acinetobacter baumannii is one of the microorganisms that can acquire carbapenem-resistance; it causes severe nosocomial infection, and is notoriously difficult to control in hospitals. Recently, a machine-learning approach was first used to analyze the ge...

BACKGROUND Corynebacterium species are part of the normal skin flora. The incidence of nosocomial infections caused by Corynebacterium species have increased substantially over the past two decades. However, the clinical course of Corynebacterium peritonitis complicating peritoneal dialysis remains unclear. METHOD We reviewed all the Corynebacterium peritonitis in our dialysis unit from 1995 ...

In this paper, we prove a theorem on convergence of Kähler-Ricci flow on a compact Kähler manifold M which admits a Kähler-Ricci soliton. A Kähler metric h is called a Kähler-Ricci soliton if its Kähler form ωh satisfies equation Ric(ωh)− ωh = LXωh, where Ric(ωh) is the Ricci form of h and LXωh denotes the Lie derivative of ωh along a holomorphic vector field X on M . As usual, we denote a Kähl...

We characterize a general solution to the vacuum Einstein equations which admits isolated horizons. We show it is a non-linear superposition – in precise sense – of the Schwarzschild metric with a certain free data set propagating tangentially to the horizon. This proves Ashtekar’s conjecture about the structure of spacetime near the isolated horizon. The same superposition method applied to th...

In this paper we construct and study a new 15-vertex triangulationX of the complex projective plane CP. The automorphism group of X is isomorphic to S4 ×S3. We prove that the triangulation X is the minimal by the number of vertices triangulation of CP admitting a chess colouring of four-dimensional simplices. We provide explicit parametrizations for simplices of X and show that the automorphism...

OBJECTIVES To assess temporal trends of hospitalizations and deaths from pertussis in Brazilian children in the period of 1996-2013. METHODS This was a descriptive ecological study of temporal trends, based on the DATASUS database. The number of hospitalizations and deaths from pertussis in children up to 19 years of age from January 1996 to December 2013 was obtained. Descriptive statistics ...
