BACKGROUND With limited sample sizes and single-institution designs, how complete response (CR) after neoadjuvant chemotherapy (NAC) influences breast conserving surgery (BCS) and its value in prognosis are not clear. METHODS A systematic research review was conducted using electronic database. The rate of clinical complete response (cCR) in BCS after NAC and these pathological CR (PCR) and n...

A new algorithm for classification of DMUs to efficient and inefficient units in data envelopment analysis is presented. This algorithm uses the non-Archimedean Charnes-Cooper-Rhodes[1] (CCR) model. Also, it applies an assurance value for the non-Archimedean                          using only simple computations on inputs and outputs of DMUs (see [18]). The convergence and efficiency of the ne...

In this paper we consider radial DEA models without inputs (or without outputs), and radial DEA models with a single constant input (or with a single constant output). We demonstrate that (i) a CCR model without inputs (or without outputs) is meaningless; (ii) a CCR model with a single constant input (or with a single constant output) coincides with the corresponding BCC model; (iii) a BCC mode...

We prove a time-space tradeo for traversing undirected graphs, using a structured model that is a nonjumping variant of Cook and Racko 's \Jumping Automata for Graphs". This material is based upon work supported in part by the Natural Sciences and Engineering Research Council of Canada, by the National Science Foundation under Grants CCR-8703196, CCR-8858799, CCR-8907960, and CCR9002891, and by...

Objective: To investigate the effects of a 12 week comprehensive cardiac rehabilitation (CCR) programme on patients who have undergone implantation of an implantable cardioverter-defibrillator (ICD). Design: Sixteen patients with ICDs (14 (88%) male, mean (SD) age 58 (10) years, range 34–74 years) were randomised to either attend an individually tailored CCR programme or receive usual care. The...

Introducción: Las enfermedades crónicas, y en particular el cáncer colorrectal (CCR), devienen una experiencia de vida crítica, pues la enfermedad invade desarticula las esferas cotidianidad identidad tanto persona como familia quien lo sufre. Objetivos: Comprender los significados vivida por personas con diagnóstico CCR su cotidiana relación atención salud recibida. Metodología: Se realizó un ...

A new staging system for multiple myeloma (MM) has utilized serum concentrations of beta2-microglobulin (Sbeta2M) and albumin as important prognostic factors for survival. Since Sbeta2M is an indicator of glomerular filtration rate, we compared the prognostic values of Sbeta2M and 24-hr urinary creatinine clearance (Ccr) in patients with MM. We retrospectively reviewed the records of 170 MM pat...

In the past, many production-scheduling methods were developed to achieve high due-date and short manufacturing lead times performance. Among them, DRUMBUFFER-ROPE (DBR) has been recognized as one of the excellent solutions. However, there are some implementation constraints (e.g., time buffer determination, setup ratio evaluation, non-CCR subordination etc.) limit its implementation performanc...

Background and objectives: Managers will be able to allocate resources optimally using performance evaluation data, specifically, efficiency evaluation of organizations. An efficiency evaluation of hospitals can be provided by determining the optimal scales for each hospital, to which optimal allocation of resources will be possible. Therefore, the present study aimed to evalua...
