Background and Aims: Patient absconding is a major health issue with economic, social, and health costs and consequences. The present study aimed to investigate the absconding rate from a emergency department and its financial burden in a public hospital in Tehran, IRAN.
Materials and Methods: This retrospective and descriptive study was carried out in the emergency department of a large public and teaching hospital in Tehran. Data were collected using the absconded patient records from 23 September 2013 to 22 September 2014. Data were analyzed using descriptive statistics.
Concerns about medical ethics, including patient’s confidentiality and hospital name were observed at all stages of study.
Results: The results of this study indicate that 774 patients had left the hospital without permission or a notice to staff, so the absconding rate in this study was about 2.4 percent. Young, male, married and uninsured patients were more absconded. Average billing per absconded patient was 1,449,738 Iranian Rials (IRR). The hospital was consequently incurred financial losses amounted to 1,122,097,212 IRR as a result of patient
Conclusion: In order to preventing and reducing the abscond rate, the following strategies are recommended: the identification of high-risk patients for further care, regular monitoring of emergency departments, good communication and interaction with the patient and his family, introducing the discharge against medical advice (DAMA) policy to patients, accurate recording of patient information to reduce the risk of abscond or
access to him/her after the absconding.

Background and Aims: Humic Acid (HA) is the most important combination of water humic materials. Removal of this compound leads to decreased production of chlorination by-products. This study set out with the aim of assessing the efficiency of O3, UV and UV/O3 in a plug-flow reactor in order to remove HA from water.
Materials and Methods: The removal efficiency was assessed at three distinct steps through raw synthetic water samples containing specific concentrations of HA and treated water measurements of humic acid. Experiments were carried out in a laboratory scale plug-flow combined UV and ozonation system. The first question in this study sought to determine the compounded impact of ozone and UV on HA removal. The subsequent second and third questions in this research were to determine the separate effects of ozone and
UV on the removal of target compound.
Results: HA removal was slightly augmented in simultaneous presence of UV and ozone reaching 74.7% at initial HA concentration of 15 mg/L, pH 8, and reaction time of 25 min. However, on the question of separate effects of ozone and UV, this study found that
the removal rate of HA, at similar situations, were 69% and 21%, respectively.
Conclusion: Integrated application of UV and ozone outperformed conventional separate use of them in terms of HA removal. Higher removal efficiencies which achieved during ozone treatment, as compared with UV, might be due to higher oxidation power of ozone and OH radicals.

Background and Aims: Gastrointestinal parasites are worldwide in distribution; the developing countries are more prone to parasitic diseases causing important public health concerns. The aim of this study was to determine the prevalence of intestinal parasites among patients referred to the laboratories of Masjed Soleiman city, Khuzestan Province in the first half of 2013.
Materials and Methods: In a cross-sectional study during 6 months, a total of 6062 stool samples from patients referred to the laboratories were tested. Stool examinations were performed by direct method and Scotch tape test for detection of protozoa and helminthes infection, respectively. All stages of this study, was in conformity by the ethical principles.
Results: Overall, the prevalence of intestinal parasites was 13.92% (844 cases). Among 6062 samples 14.84% of men and 13% female were infected. Majority of patients were infected by Giardia lamblia (54.98%), Entamoeba coli (20.14%), followed by Entamoeba histolytica (14.33%) Blastocystis hominis (3.55%) and Trichomonas (0.59%). While Hymenolepis nana (0.47%) and Enterobius vermicular (2.36%) are exhibited the minimum prevalence. The highest prevalence was seen in summer and July. Statistically there was a significant correlation between sex and infection rate (P<0.05).
Conclusion: The notable finding of this study is the high prevalence of G. lamblia and E. coli, which may be derived from poor personal hygiene, unsanitary wastewater disposal, and use of contaminated water and food.

Background and Aims: One of the most important issues of today’s world is water scarcity and pollution of the environment with heavy metals. This study aimed to investigate the removal of lead and cobalt ions by functionalized and non-functionalized single-walled carbon nanotubes from aqueous solution.
Materials and Methods: The present research was an experimental and laboratory -scale study to evaluate the removal of lead and cobalt from aqueous solution with functionalized and non- functionalized single-walled carbon nanotubes in a batch system. Samples were prepared in lab and in synthetic scale. Factors such as pH, adsorbent dosage, lead and cobalt concentrations, reaction time and reaction temperature were investigated. The concentration of metal ions was measured using atomic absorption spectrometry.
Results: According to the results, functionalization of single-walled nanotubes, increasing the adsorbent dosage, temperature, pH and initial concentrations of lead and cobalt resulted in increased removal of lead and cobalt. Most of the removal of studied metal ions was in 75 mg of adsorbent dosage, 3 mg/L of lead and cobalt, as well as 15 and 10 minutes of contact time at 35 ° C for cobalt and lead, respectively. Furthermore, the results showed better agreement with Langmuir isotherm.
Conclusion: It was found that, compared with non- functionalized nanotubes, functionalized nanotubes revealed higher adsorption capacity.
