Hands-On Parent Empowerment (HOPE) Project: Comparing Implementation in Social Service Centres and Preschools  [PDF]
Cynthia Leung, Sandra K M Tsang, Suzanne Dean
Advances in Applied Sociology (AASoci) , 2012, DOI: 10.4236/aasoci.2012.23025
Abstract: This project examined the effectiveness and implementation of an early intervention program for children from new immigrant families in Hong Kong in two delivery settings, preschools and social services centres. Participants included 141 new immigrant mothers with preschool children, from 13 preschools and two social services centres. The preschool participants were randomized into an intervention group (30-session HOPE program) and a comparison group (six-session program) at the preschool level, while participants from the two social services centres attended the 30-session HOPE program. Results indicated that the HOPE participants in preschools and social services centres reported lower post-intervention child behavior problem scores than the comparison group. Preschool HOPE participants reported higher post-intervention social support than the social services HOPE participants and comparison group participants. Qualitative information from preschool principals and centre supervisors indicated different dynamics within the two settings. Implications and suggestions for service delivery were discussed.

Probing Transport Theories via Two-Proton Source Imaging
G. Verde,P. Danielewicz,W. G. Lynch,D. A. Brown,C. K. Gelbke,M. B. Tsang,.
Physics , 2003, DOI: 10.1103/PhysRevC.67.034606
Abstract: Imaging technique is applied to two-proton correlation functions to extract quantitative information about the space-time properties of the emitting source and about the fraction of protons that can be attributed to fast emission mechanisms. These new analysis techniques resolve important ambiguities that bedeviled prior comparisons between measured correlation functions and those calculated by transport theory. Quantitative comparisons to transport theory are presented here. The results of the present analysis differ from those reported previously for the same reaction systems. The shape of the two-proton emitting sources are strongly sensitive to the details about the in-medium nucleon-nucleon cross sections and their density dependence.
Isotopic Scaling in Nuclear Reactions
M. B. Tsang,W. A. Friedman,C. K. Gelbke,W. G. Lynch,G. Verde,H. Xu
Physics , 2001, DOI: 10.1103/PhysRevLett.86.5023
Abstract: A three parameter scaling relationship between isotopic distributions for elements with Z$\leq 8$ has been observed that allows a simple description of the dependence of such distributions on the overall isospin of the system. This scaling law (termed iso-scaling) applies for a variety of reaction mechanisms that are dominated by phase space, including evaporation, multifragmentation and deeply inelastic scattering. The origins of this scaling behavior for the various reaction mechanisms are explained. For multifragmentation processes, the systematics is influenced by the density dependence of the asymmetry term of the equation of state.
Imaging Sources with Fast and Slow Emission Components
G. Verde,D. A. Brown,P. Danielewicz,C. K. Gelbke,W. G. Lynch,M. B. Tsang
Physics , 2001, DOI: 10.1103/PhysRevC.65.054609
Abstract: We investigate two-proton correlation functions for reactions in which fast dynamical and slow evaporative proton emission are both present. In such cases, the width of the correlation peak provides the most reliable information about the source size of the fast dynamical component. The maximum of the correlation function is sensitive to the relative yields from the slow and fast emission components. Numerically inverting the correlation function allows one to accurately disentangle fast dynamical from slow evaporative emission and extract details of the shape of the two-proton source.

Abstract: acy and patient tolerability of travoprost BAK-free solution in patients with open-angle glaucoma and ocular hypertension Review (3313) Total Article Views Authors: Sophia K Mirza, Sandra M Johnson Published Date July 2010 Volume 2010:4 Pages 877 - 888 DOI: http://dx.doi.org/10.2147/OPTH.S6292 Sophia K Mirza, Sandra M Johnson Department of Ophthalmology, University of Virginia, Charlottesville, Virginia, USA Abstract: The medical treatment of glaucoma has evolved significantly over the past several decades. The main driving forces behind this evolution are the safety profiles and efficacy of these medications. Prostaglandin (PG) analogs are shown to be superior to older drugs in both efficacy and tolerability. Though there are much fewer side effects that manifest after using PG analogs, the adherence and compliance to medication regimens are surprisingly lower than expected. A commonly sited reason is the ocular irritation and inflammation with these medications. Much of this inflammation can be attributed to the preservative, benzalkonium chloride (BAK). The chronic clinical and subclinical inflammation becomes increasingly detrimental when filtration surgery fails from bleb fibrosis secondary to this hypercellularity. A BAK-free formulation of a PG analog recently became available. BAK-free travoprost is reviewed here. It has demonstrated equal efficacy and less ocular surface toxicity than its preserved counterparts. It is expected to serve as an instrumental resource in managing ocular hypertension and glaucoma in patients who demonstrate significant sensitivity to BAK. More randomized, controlled, double-blind studies are encouraged to evaluate its improved safety and tolerability.

Influenza-Related Hospitalizations and Associated Comorbidities in Nebraska: 2007-2011  [PDF]
Guang-Ming Han, Sandra Gonzalez, Chrispin Chisanga, Cole Vanicek, K. M. Islam
Advances in Infectious Diseases (AID) , 2014, DOI: 10.4236/aid.2014.42015
Abstract:

Objective: Influenza afflicts approximately 5% - 20% of the US population annually. Although prevalence statistics are useful, they are insufficient to understand completely influenza on a health care system. This study estimated Nebraska’s annual hospitalization and comorbidity rates due to influenza from 2007 to 2011. Methods: Influenza was defined according to ICD-9-CM primary codes beginning with 487 or 488 in hospital discharge records. The comorbidities of patients with influenza were defined according to ICD-9-CM secondary diagnosis codes. Results: The highest yearly age-adjusted hospitalization rates were 30.6 and 31.1 per 100,000 populations for 2008 and 2009, respectively. In 2008, the highest hospitalization rate was among those aged 65 yrs and older; in 2009, the highest rate was among those younger than 5 yrs. Asthma was the most frequent comorbidity overall and among those younger than 50 yrs. Conversely, hypertension and heart failure were the most frequent comorbidities among those aged 50 yrs and older. Conclusion: These findings provide a better understanding of the influenza burden and may contribute to developing more effective influenza prevention strategies.

Abstract: 6 patients, aged 9-21 years, with repaired ALCAPA (2 Tackeuchi method, 4 direct re-implantation) underwent CMR because of clinical suspicion of myocardial ischemia. Imaging used short and long axis cine images (assess ventricular function), late-gadolinium enhancement (LGE) (detect segmental myocardial fibrosis), adenosine stress perfusion (detect reversible ischaemia) and 3D whole-heart imaging (visualize proximal coronary arteries).The left ventricular (LV) global systolic function was preserved in all patients (mean LV ejection fraction = 62.7% ± 4.23%). The LV volumes were within the normal ranges, (mean indexed LVEDV = 75.4 ± 3.5 ml/m2, LVESV = 31.6 ± 9.4 ml/m2). In 1 patient, hypokinesia of the anterior segments was visualized. Five patients showed sub-endocardial LGE involving the basal, antero-lateral wall and the anterior papillary muscle. Three patients had areas of reversible ischemia. In these 3, 3D whole-heart MRA showed that the proximal course of the left coronary artery was occluded (confirmed with cardiac catheterisation).CMR is a good, non-invasive, radiation-free investigation in the post-surgical evaluation of ALCAPA. In referred patients we show that basal, antero-lateral sub-endocardial myocardial fibrosis is a characteristic finding. Furthermore, stress adenosine CMR perfusion, can identify reversible ischemia in this group, and was indicative of left coronary artery occlusion.Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), also known as Bland-White-Garland syndrome, is a rare congenital cardiovascular defect that occurs in approximately 1 in 300 000 live births [1] or 0.25-0.5% of children with congenital heart disease [2]. The mortality of untreated ALCAPA has been estimated to be approximately 90% in the first year of life [3]. However, 5-10% of cases can survive past infancy into adulthood. These older patients can present with myocardial infarction, left ventricular dysfunction, mitral regurgitation, or si
