abstractbackground: the survival rate of preterm and low-birth-weight (lbw) infants depends on various factors such as birth weight, gestational age, and quality of care. the present study aimed at evaluating the survival rate of preterm and lbw infants, predictive factors, and the risk of mortality in three training hospitals of mashhad and tabriz cities.methods: this prospective, cohort study...

OBJECTIVES The aim of this study was to investigate the prognostic value and preoperative predictors of microvascular invasion (MVI) in solitary hepatocellular carcinoma (HCC) ≤ 5 cm without macrovascular invasion. METHODS A total of 233 consecutive HCC patients underwent curative hepatectomy were included in our study. Independent risk factors influencing the prognosis were identified, and p...

conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

INTRODUCTION Pulmonary mucoepidermoid carcinoma is a rare cancer that occurs primarily in younger patients. The prognostic factors of pulmonary mucoepidermoid carcinoma are largely undetermined, especially in elderly patients. The aim of this study was to examine the clinical characteristics and prognostic factors influencing survival after surgical resection in patients with pulmonary mucoepid...

introductionchildren with severe asthma attack are a challenging group of patients who could be difficult to treat and leading to significant morbidity and mortality. asthma attack severity is qualitatively estimated as mild, moderate and severe attacks and respiratory failure based on conditions such as respiration status, feeling of dyspnea, and the degree of unconsciousness. part of which ar...

conclusions herein we have described the stata package “adpredsurv” for calculation of the nam-d’agostino x2 goodness of fit test as well as cut point-free and cut point-based nri, relative and absolute idi, and survival-based regression analyses. we hope this work encourages the use of novel methods in examining predictive capacity of the emerging plethora of novel biomarkers. background a fun...
