Background: Detection of women at risk for dystocia will allow physicians to make preparations and treatment decisions that can minimize maternal and neonatal morbidity. We aimed to determine the risk factors for dystocia in nulliparous women. Methods: This case series enrolled 447 nulliparous women who presented with a single pregnancy in the vertex presentation and gestational age of 38-42 we...

Introduction: The geographical distribution of head and neck cancer shows considerable variation and it is site dependent. The review of the literature shows few data concerning the head and neck cancer patterns in Iran. The purpose of this study was to represent epidemiological aspects of head and neck cancers in south east of Iran. Materials &Methods: In this retrospective study, from a to...

Introduction Neoadjuvant chemotherapy (NAC) has become a standard treatment for locally advanced breast cancer. The present study was designed to investigate the predictive value of different peripheral inflammation/immune biomarker responses to NAC and prognosis in breast cancer patients. Materials and methods A total of 180 breast cancer patients treated with NAC in the First Affiliated Hos...

CONTEXT Although using a helmet is assumed to reduce the risk of head injuries in alpine sports, this effect is questioned. In contrast to bicycling or inline skating, there is no policy of mandatory helmet use for recreational alpine skiers and snowboarders. OBJECTIVE To determine the effect of wearing a helmet on the risk of head injury among skiers and snowboarders while correcting for oth...

This paper explores the language classes that arise with respect to the head count of a finite ultrametric automaton. First we prove that in the one-way setting there is a language that can be recognized by a one-head ultrametric finite automaton and cannot be recognized by any k-head non-deterministic finite automaton. Then we prove that in the two-way setting the class of languages recognized...

BACKGROUND AND PURPOSE Monocytes may contribute to secondary injury after intracerebral hemorrhage (ICH). We tested the association of absolute monocyte count with 30-day ICH case fatality in a multiethnic cohort. METHODS Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study is a prospective, multicenter, case-control study of ICH among white, black, and Hispanic patients. In 240...

In Wireless Sensor Networks (WSNs), routing algorithms can provide energy efficiency. However, due to unbalanced consumption for all nodes, the network lifetime is still prone degradation. Hence, efficient was developed in this article by selecting cluster heads (CH) with help of adaptive whale optimization (AWOA) which used reduce time-consumption delays. The multi-objective function CH select...

BACKGROUND Atherosclerosis is a chronic systemic inflammatory disease. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are systemic inflammatory markers that are correlated with poor cardiovascular outcomes. AIM To explore the relation of NLR and PLR with severity of coronary artery disease (CAD). METHODS The study population consisted of 180 consecutive patients...

The performance of indirect indices of infection in the newborn vary because of differences in techniques, including diagnostic cut off levels. We have compared serial neutrophil band cell counts with C reactive protein measured by rate nephelometry. The 'gold standard' was a positive culture and the performance of the tests was compared by the technique of receiver operating characteristics (R...

background: reservation of blood leads to blood wastage if the blood is not transfused. therefore, in some centers only blood type and screen are evaluated. in this study, the efficacy of a blood crossmatch-to-transfusion ratio was measured and then compared with the standard levels. methods: this prospective study was conducted during one year in a university hospital. during this period, 398 ...
