Hexamethylene diisocyanate (HDI) is used widely to manufacture polyurethanes for paints and coatings. It is an irritant and a chemical asthmagen. The U.S. Occupational Safety and Health Administration time-weighted average permissible exposure limit is 5 ppb and the ceiling limit is 20 ppb. We sought to develop a sensitive and specific immuno-bioassay to supplement workplace air monitoring and ...

PURPOSE The aim of this study was to assess the risk factors of prolonged hemodynamic instability (HDI) after carotid angioplasty and stenting (CAS). Herein, a simplified predictive scoring system for prolonged HDI is proposed. MATERIALS AND METHODS Sixty-six patients who had CAS from 2011 to 2016 at a single institution were evaluated. Prolonged HDI was defined as systolic blood pressure >16...

In the recent years, incidence and mortality of cancer, has been increasing in the world (1). Therefore, cancer is one of the major public health problems in many countries (2). The incidence of cancer is different in various countries. Geographical differences in the cancer incidence may be due to different distribution of cancer risk factors in the world. Many of risk factor causes cancer, a ...

The hexamethylene diisocyanate (HDI) contained polyurethane (PU) grafted multi-walled carbon nanotubes (HDI-g-MWNTs) have been synthesized by simple blending method to fabricate thermal conductive nanocomposite. This method shows that HDI-g-MWNTs can improve the interfacial compatibility between HDI-g-MWNTs and matrix. The HDI base PU thermal conductive film (HDI-PU) showed enhanced dispersibil...

BACKGROUND The purpose of this study was to determine whether psychosocial work demands have a different impact on sickness absence and presenteeism in countries with a high vs. countries with a low Human Development Index (HDI). METHODS This article is based on an analysis of the fifth European Working Conditions Survey. We investigated single items as well as complex constructs and indices....

INTRODUCTION The effect of socioeconomic status (SES) on stroke mortality at population level has been controversial. This study explores the association of SES in childhood and adulthood with stroke mortality, as well as variations in this association among countries/regions. METHODS Sex-specific stroke mortality at country level with death registry covering ≥ 70% population was obtained fro...

The most limiting weakness of the human development index (HDI) is that it looks only at average achievements and does not take into account the distribution of human development within a country or population subgroups. All previous attempts to capture inequality in the HDI have also used aggregate information and there exists no HDI at the household level. This paper provides a method and ill...

PURPOSE During carotid angioplasty and stenting (CAS), hemodynamic instability (HDI) can occur, possibly causing post-procedural ischemic complications. The goal of this study was to investigate the risk factors of HDI focusing on characteristics of plaque. MATERIALS AND METHODS Thirty nine CAS patients were retrospectively evaluated for HDI. Prolonged HDI that lasted over 30 minutes was anal...

PURPOSE To assess the benefits of adjuvant high-dose interferon alfa (HDI) treatment for patients with high-risk melanoma. METHODS We designed a decision-analytic probabilistic Markov model to simulate the natural history of patients with stage IIIA, IIIB, and IIIC melanoma and evaluate the outcomes with and without HDI treatment. Outcomes were in quality-adjusted life years (QALYs) and incre...
