Background: The need for better healthcare has grown significantly in recent years. In addition, the rising healthcare costs in the U.S. and in many European countries have forced many patients to seek medical treatment abroad, which has created the demand for medical tourism. With little yet known as to the perception of a medical tourist's destination selection, this study aims to explore medical tourist's perception in selecting their destination while going for medical treatment.
Methods: Realizing the current need to examine closely the perception of medical tourists, this study had conducted a secondary study to collect data for assessing and identification of the key factors on patient's perception and destination selection criteria.
Results: The result confirms the existence of a very strong relationship between cost, service quality, treatment types and availability and marketing impact on the perception of the medical tourists' in selecting their medical tourism destination.
Conclusion: This study offers support for the proposed conceptual model and an empirical basis for comparison in future research. -
Background: Micronutrient deficiency is one of the major public health problems in the Middle East affecting economic, political and social development of countries. The three commonest micronutrient deficiencies belong to iron, iodine and vitamin A.
Methods: we conducted a systematic review of published English articles in the Middle East countries using databases from PubMed, World Health Organization and Food and Agriculture Organization from 1985 onward. A total of 6050 articles were identified and after evaluation based on eligibility criteria, 81 articles included in this systematic review.
Results: Despite implementation of flour fortification other control strategies, the prevalence of iron deficiency is moderate to severe in the Middle Eastern countries, because of ineffective iron fortification program, food interaction and hemoglobin application as anemia indictors in these countries. Mild to severe iodine deficiency disorders exist in many countries of the Middle East, due to lack of effective iodine supplementation program. The prevalence of vitamin A deficiency is mild to severe and there is lack of vitamin A fortification program in many countries in this region.
Conclusion: Despite unharmonized efforts to control malnutrition of micronutrients, iron, iodine and vitamin A deficiencies are still exist in some countries of the Middle East. Effective, well controlled and harmonized programs for elimination of micronutrient deficiencies need to be initiated for governments and supported by international organizations in this region. -
Background: Metabolic syndrome (MS) is emerging as a serious public health problem in Korea. The purpose of this study was to examine the effects of 12 weeks of combined exercise training on body composition and MS factors in obese Korean female college students.
Methods: Subjects were randomly assigned to exercise (n = 7) and control (n = 9) groups. The exercise group trained for 80 min/day, for 3 day/week for 12 weeks. Each exercise session comprised 3 phases: warm-up for 10 min, main exercise for 60 min (consisting of aerobic exercise for 30 min and resistance exercise for 30 min), and cool down for 10 min.
Results: The exercise intensity for aerobic exercise was 60-80% of the heart rate reserve (HRR) for 30 min, while the resistance exercises were 10-15 repetitions maximum (RM) for 30 min. Two-way repeated analysis of variance (ANOVA) was used for statistical analysis. There were no interaction effects (time × group) on the MS-related factors of blood lipid composition such as triglycerides (TGs), high-density lipoprotein (HDL), glucose, total cholesterol (TC), and low-density lipoprotein (LDL). However, interaction effects were observed (time × group) on percent body fat (P = 0.006), waist circumference (WC; P < 0.001), systolic blood pressure (SBP; P = 0.010), and diastolic blood pressure (DBP; P = 0.007).
Conclusions: A 12-week supervised combined exercise program could effectively reduce percent body fat, WC, SBP, and DBP. However, it was not effective on MS-related factors of blood lipid composition such as TG, HDL, glucose, TC, and LDL in a sample population of obese Korean female college students.

Background: Elder abuse and neglect (EAN) comprises emotional, financial, physical, and sexual abuse, neglect by other individuals, and self-neglect. Elder abuse and neglect in seniors with psychiatric morbidity was not monitored in the Czech Republic at all, despite the literature shows mental morbidity as one of the important risk factor for developing elder abuse and neglect.
Methods: We designed comparative cross sectional study comprising 305 seniors hospitalized in Mental Hospital Kromeriz in June 2011 - group of 202 seniors hospitalized due to mental disorder in psychogeriatric ward and group of 103 seniors hospitalized due to somatic disorder in internal ward. Content analysis of medical records was done in both groups of seniors, with regards to symptoms of elder abuse. Then, we discussed the topic of elder abuse with 30 nurses of psychogeriatric ward in focus group interview.
Results: Between two compared groups of seniors we detected statistically higher prevalence of elder abuse in seniors with psychiatric morbidity (48 cases, 23.8% prevalence of EAN), compared to somatically ill seniors (3 cases, 2.9%). As for nursing staff, 5 from 30 nurses (16.7%) have never heard about symptoms of elder abuse and neglect, 10 from 30 nurses (33.3%) had just a partial knowledge about elder abuse and neglect and its symptoms, the rest of nurses (15 from 30 nurses, 50.0%) had good knowledge about elder abuse and neglect and its symptoms.
Conclusion: Elder abuse and neglect seems to be a relevant problem in senior population with mental disorders. Development of educational programs for nursing and medical staff about Elder abuse and neglect (symptoms of EAN, early detection of EAN, knowledge how to report cases of EAN) could improve the situation and help mentally ill seniors to better quality of life.

Background: Both increased arterial stiffness and hyperuricaemia are associated with elevated cardiovascular risks. Little is known about the relations of serum uric acid (UA) level to regional arterial stiffness and wave reflection. The aim of the study was to investigate the gender-specific association of serum UA and indices of arterial function in a community-based investigation in China.
Methods: Cross-sectional data from 2374 adults (mean age 58.24 years) who underwent routine laboratory tests, regional pulse wave velocity (PWV) and pulse wave analysis measurements were analyzed in a gender-specific manner. None of the participants had atherosclerotic cardiovascular disease, chronic renal failure, systemic inflammatory disease, gout, or were under treatment which would affect serum UA level.
Results: Men had higher serum UA level than women. Subjects with hyperuricaemia had significantly higher carotid-ankle PWV in both genders (P< 0.05), and the carotid-femoral PWV (PWVc-f) was higher in women (P< 0.001) while the augmentation index was marginally lower in men (P = 0.049). Multiple regression analysis showed that serum UA was an independent determinant only for PWVc-f in women (β = 0.104, P = 0.027) when adjusted for atherogenic confounders. No other independent relationship was found between UA level and other surrogates of arterial stiffness.
Conclusions: Serum UA levels are associated with alterations in systemic arterial stiffness that differ in men and women. Women might be more susceptible to large vascular damage associated with hyperuricaemia.

Background: Examining the quality of nursing care from the patient's perspective is an important element in quality evaluation. The extent to which patients' expectations are met will influence their perceptions and their satisfaction with the quality of care received.
Methods: A cross- sectional survey was conducted among admitted patients at King Khalid Teaching Hospital, Riyadh, Saudi Arabia. Data were collected (from January 2011 to March 2011) from a convenience sample of 448 patients using a 42- items questionnaire assessing six dimensions of the nursing care provided to, during hospitalization.
Results: On a four-point scale (4-higly agree,3-agree, 2-disagree, and 1-higly disagree). The individual items of nursing care showing the lowest means were the information received from the nurses about self-help (2.81), the information about the laboratory results (2.76) and the way the nurse shared the patient's feeling (2.72). A strong correlation existed between the overall perception level and the variables of gender (P=0.01), and the types of department (0.004).
Conclusion: The findings of this study demonstrate negative experiences of patients with nursing care in dimensions of information, caring behavior, and nurse competency and technical care. Awareness of the importance of these dimensions of nursing care and ongoing support to investigate patients' perception periodically toward quality of nursing care are critical to success the philosophy of patient centered health care.

Background: This study aimed at estimating the proportion of diabetes as a risk factor to the attributable burden of cardiovascular diseases in Iran.
Methods: Comparative Risk Assessment methodology was used to calculating Potential Impact Fraction (PIF). To calculate PIF, data on the prevalence of newly diagnosed diabetes mellitus (NDM) and known diabetes mellitus (KDM) were obtained from 3rd Iranian surveillance of risk factors of non- communicable diseases and data on corresponding measures of effect were derived from a cohort study. PIF were estimated on both theoretical minimum and feasible minimum risk. Uncertainty for the attributable burden was estimated by Monte Carlo simulation-modeling techniques incorporating sources of uncertainty.
Results: According to multivariate- adjusted hazard ratios, by reducing the prevalence of Iranian women with diabetes from 10.05 percent to the feasible minimum risk level i.e. 5 percent, 6.8% (95% uncertainty intervals: 3.5- 9.8) of attributable Disability Adjusted Life Years (DALYs) to CVD are avoidable and the corresponding value for men were 3.1% (95% uncertainty intervals: 1.4- 4.8).
Conclusion: Although data on the prevalence of diabetes and corresponding measures of associations were obtained from an updated and country- specific source, but to better priority setting, PIF should be applied to updated and revised burden of CVDs.

Background: To assess accessibility of iodinated salt and urinary iodine concentrations (UIC) during pregnancy. This cross-sectional study was carried out between October and December, 2009 in Urmia County, West Azerbaijan (WA), Iran.
Methods: Data on demographic characteristics and iodinated salt accessibility were gathered through a questionnaire at 1st trimester. Household salt samples and urine samples (1st -and 3rd trimesters) were analyzed for iodine content. Pregnant women (n=490) at 1st trimester were interviewed. Of these, 490 subjects (12 prenatal care centers) were enrolled.
Results: All participants declared that they were exclusive users of iodinated salt. Segregation of the household salt samples according to iodine content (0, 8, 15 and 30 ppm) revealed that the respective distributions were 3.3%, 1.4%, 23.7% and 71.6%. Median UIC levels at 1st and 3rd trimesters were 73.5 µg/L and 114µg/L respectively. Accordingly, 86% and 70% of participants exhibited UIC < 150 µg/L.
Conclusion: Median UIC during pregnancy in WA is markedly lower than those previously reported for regions with adequate iodine status in the country. Thus, extra iodine is needed to maintain adequate iodine store during gestation. In addition, this preliminary study reveals that a significant proportion (28%) of the household salt samples had low iodine content (≤ 15 ppm) although a level (>20 and <40 ppm) is mandatory in Iran. Further studies are deemed necessary to elucidate the cause(s) for manifestation iodine deficiency among pregnant women despite 20 years after iodine fortification strategy.

Background: Welding can produce dangerous fumes containing various metals especially carcinogenic ones. Occupational exposure to welding fumes is associated with lung cancer. Therefore, welders in Gas Transmission Pipelines are known as a high-risk group. This study was designed to determinate the amounts of metals Cr, Ni, and Cd in breathing zone and urine of welders and to assess the possibility of introducing urinary metals as a biomarker due to occupational exposure.
Methods: In this cross sectional study, 94 individuals from Gas Transmission Pipelines welders, Iran, Borujen in 2011 were selected and classified into 3 groups including Welders, Back Welders and Assistances. The sampling procedures were performed according to NIOSH 7300 for total chromium, nickel, and cadmium and NIOSH 7600 for Cr+6. For all participants urine samples were collected during the entire work shift and metals in urine were determined according to NIOSH 8310.
Results: Back Welders and Assistances groups had maximum and minimum exposure to total fume and its elements, respectively. In addition, results showed that there are significant differences (P<0.05) between Welders and Back Welders with Assistances group in exposure with total fume and elements except Ni. Urinary concentrations of three metals including Cr, Cd and Ni among all welders were about 4.5, 12 and 14-fold greater than those detected in controls, respectively. Weak correlations were found between airborne and urinary metals concentrations (R2: Cr=0.45, Cd=0.298, Ni=0.362).
Conclusion: Urinary metals concentrations could not be considerate as a biomarker for welders' exposure assessment.

Background: Human enteroviruses (EVs) may have a role as a possible risk factor in the pathogenesis of MI. The aim of this study was to evaluate the presence of enterovirus genomic RNA in peripheral blood samples of patients with acute myocardial infarction (MI).
Methods: We investigated the presence of enterovirus genomic RNA in the peripheral blood of 115 patients with acute MI hospitalized in the Coronary Care Unit of Imam Reza and Ghaem University Hospitals (Mashhad, Iran) by RT-PCR using the virus specific primers.
Results: The subjects' mean (±SD) age was 63.5 (±9.4) years (range: 38-82) and 38.3 % of the subjects were female. Of 115 patient specimens, 3 (2.6%) were positive in RT-PCR.
Conclusion: The prevalence of enterovirus in MI patients is considerable. More investigations are needed to determine the causal role of enteroviruses in MI.

Background: Herpes simplex virus (HSV) type 1 and 2 are common infectious agents worldwide. Data on prevalence of HSV-1 and HSV-2 infection are limited in Asia, especially in Iran. The aim of this study was to determine the seroprevalence of HSV type 1 and 2 based on age, gender, marital status, education, living area, job, symptoms and history of disease variables.
Methods: The study population included 800 randomly selected persons from laboratories in Gilan Province, Iran, from 2010 to 2011. Demographic data gathered by a well-designed questionnaire and for serological studies, blood samples were collected and centrifuged. ELISA HSV-1, 2 and HSV-2 specific ELISA kits were used to determine IgG type specific antibodies in sera samples. Person's chi-square test was applied to compare HSV-1 and HSV-2 seropositivities.
Results: HSV-1 and HSV-2 IgG antibodies were positive in 467 (58.4%) and 28 (3.5%) subjects, respectively. There was significant correlation between age, marital status, job, symptoms, history of disease and HSV seroprevalence (P<0.05).
Conclusion: Our findings were in agreement with prior studies in which HSV-1 infections was more prevalent than HSV-2 and seropositivity increased with age.

Background: Cutaneous leishmaniasis caused by L. major is an important public health problem in endemic areas. The aim of this study was to explore the therapeutic effect of microwave and or infrared radiation in the treatment of lesion induced in BALB/c mice by L. major inoculation.
Methods: The footpad lesion was induced in BALB/c mice by inoculation of L. major promastigotes subcutaneously. The lesion was treated with 600 watts power, 2.450 GHz frequency and/or infrared device with 150 watts and a wave length of 890 nanometres. The size of the lesion was recorded by footpad swelling measurement every 10 days.
Results: The lesion growth was significantly hampered in treated mice compared with the untreated control group (P<0.05). Infrared radiation was more effective than microwave in inhibiting ulcer enlargement.
Conclusion: Infrared radiation and microwave significantly hampered L. major lesion growth in BALB/c mice. This therapeutic effect was more in infrared radiation treated mice than microwave treated mice.

Background: The aim of this study was identification of the epidemiology of Prototheca zopfii species from the milk samples of dairy cattle in Isfahan, central Iran.
Methods: Milk samples were obtained from 230 dairy cattle, 130 with and 100 without mastitis, in Isfahan. The samples were cultured in Prototheca Isolation Medium (PIM) and Sabouraud's dextrose agar. All P. zopfii isolates were identified by morphological and biochemical methods. Then, as a confirmatory test they were examined by genotype-specific PCR.
Results: Four P. zopfii strains (3.07%) were isolated from the 130 samples of dairy cattle with clinical mastitis and there was no isolation from totally 100 samples of healthy bovines without mastitis. Specific PCR product (about 946 bp) was detected in four isolates.
Conclusion: It seems that P. zopfii genotype II plays a key role in affecting bovine mastitis that confirmed other previous studies. Our study was the first, which identified the Prototheca species by traditional and molecular methods in Iran and Middle East as well.

Despite importance of blood transfusion services as life saving procedures, some countries are unable to meet their national requirements for blood and blood components in a timely manner. Since establishment of Iran Blood Transfusion Organization (IBTO) in 1974 as an integral part of national health system, Iran has experienced a drastic improvement both in availability and safety of blood and blood products. Iran now has not only reached to a 100% non remunerated voluntary blood donation but also secured a national self sufficiency of blood and blood components. Efforts of IBTO as the sole player of transfusion medicines in Iran enabled the country for timely providing of life saving blood transfusion services for all Iranian patients in need of such services. In order to meet the country's demand in 2011 about 2 million units of whole blood for a population of about 75 million collected by IBTO. This indicates 26.2 donations per 1000 population. Currently about 94% of blood donors in Iran are 25-35 years old males and contribution of female donors in blood donation is less than 6%. IBTO screen all donated blood for important transfusion transmissible infections such as HBV, HIV, HCV and syphilis. Prevalence of HBsAg, HCV and HIV in donated blood in IBTO in 2011 was 0.20%, 0.06% and 0.004% respectively.
