Hepatitis C among families of Thalassemic patients suffering from Hepatitis C in Shahrekord, 1999

Considering the high prevalence of Hepatitis C and its undetermined routes of transmission in 35% of the cases, this survey was performed to find the rate of intrafamilial transmission among the families of Thalassemic patients suffering from Hepatitis C in Shahrekord, 1999. The tests of ALT and anti-HCV antibody were carried out in 136 persons from 25 Thalassemic families at two phases of 6 months apart. The average age of the sample was 22.4±14.3 and 51.5% were female. Five persons had contact with the patient’s needle (Needle stick). No rise in ALT was seen and all of the cases were anti-HCV negative. Also, no case of Hepatitis C was found among the families of Thalassemic patients. In conclusion, intrafamilial transmission was not detected but due to its possibility and since a great number of patients has no other risk factor, this transmission rout could not be ignored

Multicultural Face Recognition Memory And Own-Race-Bias Among Adults With Acquired Brain Injury

Own-race bias (ORB) is a well-documented phenomenon that may influence face memory, such that face memory is improved when the observed target matches the observer’s racial background. However, the clinical measures widely used in neuropsychological evaluations lack racial diversity that may disenfranchise and disadvantage minority patients. Further, these existing measures have been criticized for having inconsistent visual contrast and facial content, as well as too much variability of non-facial information which may confound its acceptability as a measure of face memory specifically. To address these limitations, standardized, multicultural images with validated facial expressions (Beaupré et al., 2000) were used to create the Multicultural Facial Recognition Test (MCFR) to evaluate face recognition memory and ORB in a clinically relevant sample of persons with acquired brain injuries. Method: One-hundred fifteen adults (63 Black, 52 White) with history of acquired brain injury participated. The participants ranged in age from 18 to 79 and were on average 12 years post injury. Participants completed a battery of cognitive tests, including the MCFR, the criterion Warrington Recognition Memory Test (RMT-F), and a post-test survey to provide consumer feedback on the MCFR. Results: Internal consistency reliability of the MCFR was low, but the MCFR showed evidence of convergent validity as expected by theory. The MCFR correlated with the RMT-F and a measure of visual memory. However, the patterns of correlations among the MCFR and the cognitive measures differed significantly for Black and White participants. Additionally, evidence for ORB was present; however, this finding was only significant among Black participants. Although both racial groups performed best on the RMT-F, both groups also endorsed preferring the MCFR over the RMT-F. Conclusions: The findings support evidence of ORB, but also suggest that ORB may be differently experienced by ABI patients of different racial groups. These findings highlight the need to include multicultural stimuli in the development of valid tests of face memory, as well as, the necessity to include multicultural participants in clinical research, as findings from the dominant culture may not generalized to minority populations. Further evaluation of the psychometric properties of the MCFR should be pursued

The effect of 12 weeks regular physical activity and vitamin E in the treatment of non-alcoholic steatohepatitis: A pilot study

Background: Despite the prevalence of Non-Alcoholic Fatty Liver Disease (NAFLD) and Non-Alcoholic Steatohepatitis (NASH), there was no treatment has been proven to be effective in these common diseases. Although many studies have shown that lifestyle modifications such as increasing physical activities and exercise could be effective in the treatment of these common diseases, the optimal strategy was still not determined. According to the beneficial effects of antioxidant agents in the treatment of NASH, vitamin E has been used for this purpose by some clinicians. We designed this study for assessing beneficial effects of regular physical activity on the biochemical and imaging responses in patients with NASH and comparing this with vitamin E as an accepted treatment for NASH. Materials and Methods: This study was Randomized and single-blind clinical trials were carried out in Gonbad-e Kavus through which a total of 30 consecutive patients with the ultra sonographic diagnosis of non-alcoholic steatohepatitis (NASH)were enrolled and randomized to one of the three groups: Vitamin E 800 mg/day, regular physical activity, or both. Results: In all treatment groups improvement in liver transaminases level, serum lipids and ultrasonographic grading of fatty liver occurred after three months of treatment. When these decrement was compared between the treatment groups, there was no statistically significant difference in the value of improvement between the three groups (ANOVA: p>0.5). I.e. all three interventions improved the biochemical and ultrasonographic finding of fatty liver in the same way. Both groups with regular exercise had significant mean weight loss in comparison with the vitamin E group (a mean decrease of 3.0 kg in exercise group, 5.8 kg in subjects on regular exercise plus vitamin E and 0.2 kg in vitamin E group, ANOVA: p=0.04). Conclusion: There were no significant differences between exercise and vitamin E alone or in combination regarding the reduction in the level of liver enzymes and sonographic evidences of fatty liver although both resulted in significant improvements in biochemical endpoints. This implies that physical activity could be considered as effective as vitamin E in the improvement of biochemical and ultrasonographic presentations of NASH and the addition of Vitamin E does not offer any benefits. According to the findings of this pilot study a full-powered study with a control group should be designed. © 2015, Iranian Association of Gastroenterology and Hepatology. All rights reserved

The survey of the effect of ginger extract on gastric residual volume in mechanically ventilated patients hospitalized in the Intensive Care Units

Background and purpose: Delayed gastric emptying in mechanically ventilated patients is common. According to evidences, Ginger can accelerate gastric emptying. This study aimed to determine the effect of ginger extract on gastric residual volume of patients admitted to the Intensive Care Unit. Materials and Methods: In this double-blind randomized controlled clinical trial with before and after schematization, 24 mechanically ventilated patients hospitalized in ICUs were divided into two groups, intervention group (12 patients) and control group (n = 12) after matching for sex and severity of disease. After 48 hours of feeding with a standard gavage solution, the intervention group received 120mg of ginger extract in 4 days and the control group received 5 ml water as placebo in 4 days. The mean residual volume was recorded in the fifth and the sixth days. Data analysis was done with independent and paired T-tests at a significance level of 0.05. Results: The mean residual volume in the first 48 hours was not significantly different between the groups. But after 48 hours of starting treatment, the average of mean and standard deviation of the residual volume in the fifth and sixth days were (24.58±16.81) in intervention group and (108.33±15.09) in control group that according to the Independent T-test showed a significant difference (P <0.0001). Discussion and Conclusion: The result of this study showed that ginger extract reduces gastric residual volume in mechanically ventilated patients hospitalized in intensive care units compared with placebo. © 2013 AENSI Publisher All rights reserved

ALMA Observations of Giant Molecular Clouds in the Starburst Dwarf Galaxy Henize 2-10

We present new ${ }^{12}$CO(J=1-0) observations of Henize 2-10, a blue compact dwarf galaxy about 8.7 Mpc away, taken with the Atacama Large Millimeter Array. These are the highest spatial and spectral resolution observations, to date, of the molecular gas in this starburst galaxy. We measure a molecular mass of $1.2\times10^8 M_\odot$ in Henize 2-10, and most of the molecular gas is contained within a region having a size of about 310 pc. We use the CPROPS algorithm to identify 119 resolved giant molecular clouds distributed throughout the galaxy, and the molecular gas contained within these clouds make up between 45 to 70% of the total molecular mass. The molecular clouds in Henize 2-10 have similar median sizes (~26 pc), luminous masses (~$4\times 10^5$ $M_\odot$), and surface densities (~$180$ $M_\odot$ pc$^{-2}$) to Milky Way clouds. We provide evidence that Henize 2-10 clouds tend to be in virial equilibrium, with the virial and luminous masses scaling according to $M_{vir}\propto M_{lum}^{1.2\pm0.1}$, similar to clouds in the Milky Way. However, we measure a scaling relationship between luminous mass and size, $M_{vir}\propto R^{3.0\pm0.3}$, that is steeper than what is observed in Milky Way clouds. Assuming Henize 2-10 molecular clouds are virialized, we infer values of the CO-to-H$_2$ conversion factor ranging from 0.5 to 13 times the standard value in the Solar Neighborhood. Given star formation efficiencies as low as 5%, the most massive molecular clouds in Henize 2-10 currently have enough mass to form the next generation of super-star clusters in the galaxy

Electronic Cigarette Use and Associated Risk Factors in U.S.-Dwelling Pacific Islander Young Adults.

Background: E-cigarette use is rapidly increasing among US young adults, heightening their risk for vaping-related illnesses. Yet, little is known about e-cigarette use among young adult Native Hawaiians and Pacific Islanders (NHPI): an indigenous-colonized US racial group rarely described in research literature. This exploratory study provides the first known data on e-cigarette use and potential risk factors in NHPI young adults. Method: Self-report data were collected from 143 NHPI young adults (age 18-30 years) living in two large NHPI communities: Samoans in urban Los Angeles County and Marshallese in rural Arkansas. We assessed rates of e-cigarette, cigarette, alcohol, and marijuana use, and positive and negative outcome expectancies from e-cigarettes, that is expected outcomes from e-cigarette use. To identify potential risk factors for NHPI e-cigarette use, regressions explored associations between participants' current e-cigarette use with current cigarette, alcohol, and marijuana use, and e-cigarette outcome expectancies. Results: Among NHPI young adults, lifetime e-cigarette use rate was 53% and current use rate was 39%. Current rate of dual e-cigarette/cigarette, e-cigarette/alcohol, and e-cigarette/marijuana use was 38%, 35%, and 25%, respectively. In our regression models, current marijuana use and positive e-cigarette outcome expectancies were significantly associated with current e-cigarette use. Conclusions: E-cigarette use is common among NHPI young adults, exceeding rates for other at-risk racial groups. Marijuana use and positive expectations about e-cigarette use may represent potential e-cigarette use risk factors. Collectively, findings underscore the need for additional research to further explore the scope of, and risk and protective factors for, e-cigarette use in this understudied high-risk population

Experimental study on the high-velocity impact behavior of sandwich structures with an emphasis on the layering effects of foam core

In this study, the effects of the core layering of sandwich structures, as well as arrangements of these layers on the ballistic resistance of the structures under high-velocity impact, were investigated. Sandwich structures consist of aluminum face-sheets (AL-1050) and polyurethane foam core with different densities. Three sandwich structures with a single-layer core of different core densities and four sandwich structures with a four-layer core of different layers arrangements were constructed. Cylindrical steel projectiles with hemispherical nose, 8 mm diameter and 20 mm length were used. The projectile impact velocity range was chosen from 180 to 320 m/s. Considering constant mass and total thickness for the core, the results of the study showed that the core layering increases the ballistic limit velocity of the sandwich structures. The ballistic limit velocity of the panels with a four-layer core of different arrangements, compared to the panel with the single-layer core, is higher from 5% to 8%. Also, for the single-layer core structure, by increasing the core density, the ballistic limit velocity was increased. Different failure mechanisms such as plugging, petaling and dishing occurred for the back face-sheet. The dishing area diameter of back face-sheets was proportional to the ballistic resistance of each sandwich structure
