Comparison of the perception of ideal body images of Ghanaian men and women
NA Jumah, RB Duda
African Journal of Health Sciences , 2007,
Abstract: Obesity is now a worldwide public health problem. The prevalence of obesity and obesity-linked illnesses continues to increase in regions of the developing world that were previously unaffected by such conditions. Reasons for this increase include changes in diet, occupations, activity and cultural norms. The purpose of this study was to test the hypothesis that Ghanaian men preferred Ghanaian women to be of the larger, traditional body size. Ghanaian men and women were selected at random to complete a survey and to select a body image that best represented their current body image (CBI), and an ideal body image (IBI) for men and women. The results showed that 69.7% of men selected the IBI for women to be in the normal BMI range while only 44.7% felt that women preferred to be in the normal body mass index BMI category. In comparison, 56.5% of women selected the IBI for women in the normal BMI range and 48.4% stated that they believed men preferred a woman in the normal BMI range. An additional 33.9% of women reported that they felt men preferred a women's figure in the underweight range. The difference in men's selection and their perception of a women's selection of the IBI for a woman was significant (p=0.05). Men were significantly more likely to be satisfied with their current body image (CBI) than women (43.9% vs. 22.6%, respectively, OR 1.12 [1.03-1.20], p=0.003). Women were significantly more likely to change their CBI to improve their health (OR 2.97 [1.31 – 6.71], p=0.009). It is concluded that the majority of men and women in this cohort prefer women to be of a normal BMI but the perceptions of the preference of the opposite gender are significantly different. This information now allows us to proceed with an educational and medical program aimed to reduce obesity and the consequences of obesity-linked illnesses in this population.

Abstract: ct of pharmacist interventions on patients' adherence to antidepressants and patient-reported outcomes: a systematic review Review (4429) Total Article Views Authors: Al-Jumah KA, Qureshi NA Video presented by Naseem Akhtar Qureshi Views: 106 Published Date January 2012 Volume 2012:6 Pages 87 - 100 DOI: http://dx.doi.org/10.2147/PPA.S27436 Received: 18 October 2011 Accepted: 30 November 2011 Published: 31 January 2012 Khalaf Ali Al-Jumah1, Naseem Akhtar Qureshi2 1Specialist Pharmacist, Al-Amal Mental Health Complex, Riyadh, 2General Administration for Medical Research and Mental Health and Social Services, Ministry of Health, Riyadh, Kingdom of Saudi Arabia Background: Pharmacist intervention in improving patient adherence to antidepressants is coupled with better outcomes. Aims: The aim of this investigation was to systematically examine the published literature to explore different types of pharmacist interventions used for enhancing patient adherence to antidepressant medications. Three specific questions guided the review: what is the impact of pharmacist interventions on adherence to antidepressant medication? What is the impact of pharmacist interventions on patient-reported outcomes and patient satisfactions? What are the types of interventions used by pharmacists to enhance patients' adherence to antidepressants? Search strategies: A systematic review of the literature was conducted during August–November 2010 using PubMed, BIOSIS Previews Web of Science, ScienceDirect, the Cochrane Library, PsycINFO , IngentaConnect , Cambridge Journals Online, and Medscape databases. Key text words and medical subject headings included pharmacist intervention, medication intervention, depression, medication adherence, health-related quality of life, patient-reported outcomes, and antidepressants. Results: A total of 119 peer-reviewed papers were retrieved; 94 were excluded on the basis of abstract review and 13 after full-text analysis, resulting in twelve studies suitable for inclusion and intensive review. The most common intervention strategy that pharmacists utilized was a combination of patient education and drug monitoring. A cumulative patient adherence improvement in this review ranged from 15% to 27% attributed to utilization of different interventions and different combinations of interventions together with patient satisfaction with the treatment when depression improved. Conclusion: This review suggests that pharmacist intervention is effective in the improvement of patient adherence to antidepressants. This may be a basis for more studies examining the effectiveness of innovative interventions by pharmacists to enhance patient adherence to antidepressant medications.

Denoising of an Image Using Discrete Stationary Wavelet Transform and Various Thresholding Techniques  [PDF]
Abdullah Al Jumah
Journal of Signal and Information Processing (JSIP) , 2013, DOI: 10.4236/jsip.2013.41004
Abstract:

Image denoising has remained a fundamental problem in the field of image processing. With Wavelet transforms, various algorithms for denoising in wavelet domain were introduced. Wavelets gave a superior performance in image denoising due to its properties such as multi-resolution. The problem of estimating an image that is corrupted by Additive White Gaussian Noise has been of interest for practical and theoretical reasons. Non-linear methods especially those based on wavelets have become popular due to its advantages over linear methods. Here I applied non-linear thresholding techniques in wavelet domain such as hard and soft thresholding, wavelet shrinkages such as Visu-shrink (non-adaptive) and SURE, Bayes and Normal Shrink (adaptive), using Discrete Stationary Wavelet Transform (DSWT) for different wavelets, at different levels, to denoise an image and determine the best one out of them. Performance of denoising algorithm is measured using quantitative performance measures such as Signal-to-Noise Ratio (SNR) and Mean Square Error (MSE) for various thresholding techniques.

Abstract:

The problem of estimating an image corrupted by additive white Gaussian noise has been of interest for practical reasons. Non-linear denoising methods based on wavelets, have become popular but Multiwavelets outperform wavelets in image denoising. Multiwavelets are wavelets with several scaling and wavelet functions, offer simultaneously Orthogonality, Symmetry, Short support and Vanishing moments, which is not possible with ordinary (scalar) wavelets. These properties make Multiwavelets promising for image processing applications, such as image denoising. The aim of this paper is to apply various non-linear thresholding techniques such as hard, soft, universal, modified universal, fixed and multivariate thresholding in Multiwavelet transform domain such as Discrete Multiwavelet Transform, Symmetric Asymmetric (SA4), Chui Lian (CL), and Bi-Hermite (Bih52S) for different Multiwavelets at different levels, to denoise an image and determine the best one out of it. The performance of denoising algorithms and various thresholding are measured using quantitative performance measures such as, Mean Square Error (MSE), and Root Mean Square Error (RMSE), Signal-to-Noise Ratio (SNR), Peak Signal-to-Noise Ratio (PSNR). It is found that CL Multiwavelet transform in combination with modified universal thresholding has given best results.

The Immunomodulatory and Neuroprotective Effects of Mesenchymal Stem Cells (MSCs) in Experimental Autoimmune Encephalomyelitis (EAE): A Model of Multiple Sclerosis (MS)
Mohammed A. Al Jumah,Mohamed H. Abumaree
International Journal of Molecular Sciences , 2012, DOI: 10.3390/ijms13079298
Abstract: Mesenchymal stem cells (MSCs) are multipotent cells that differentiate into the mesenchymal lineages of adipocytes, osteocytes and chondrocytes. MSCs can also transdifferentiate and thereby cross lineage barriers, differentiating for example into neurons under certain experimental conditions. MSCs have anti-proliferative, anti-inflammatory and anti-apoptotic effects on neurons. Therefore, MSCs were tested in experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), for their effectiveness in modulating the pathogenic process in EAE to develop effective therapies for MS. The data in the literature have shown that MSCs can inhibit the functions of autoreactive T cells in EAE and that this immunomodulation can be neuroprotective. In addition, MSCs can rescue neural cells via a mechanism that is mediated by soluble factors, which provide a suitable environment for neuron regeneration, remyelination and cerebral blood flow improvement. In this review, we discuss the effectiveness of MSCs in modulating the immunopathogenic process and in providing neuroprotection in EAE.
Computed tomography features of head injury in Ghanaian children
MO Obajimi, KB Jumah, WO Brakohuapa, W Iddrisu
Nigerian Journal of Surgical Research , 2002,
Abstract: Background: Injuries to the head are common in children. There are several reports in literature of head injury and evaluation with computed tomography scan (CT scan) but only a few focus on children. Method: A retrospective review of films and reports of the CT scans of 41 children with head injury. Results: Positive CT findings were noted in 19 (46.3%). Road traffic accident was found to be the commonest cause of injury with the highest incidence in the 5 – 9 year age group. Cranial fractures were the commonest (73.68%) CT findings especially in the frontal and parietal bones. Intracranial haemorrgage was outlined in 47.37%. In classifying the extent of head injury type 3 with intracranial injury alone occurred most (58.8%). Extraparenchymal haemorrages occurred more in 69.2% than the intracerebral variety (30.8%) Hydrocaphalus and cerebral oedema were also reported. Conclusion: CT scan provides accurate non-invasive diagnosis of fractures, intracranial haemorrhages and other sequale of head injury. However, it should be done only when clinically indicated to reduce cost and avoid unnecessary irradiation
Review of national research ethics regulations and guidelines in Middle Eastern Arab countries
Alahmad Ghiath,Al-Jumah Mohammad,Dierickx Kris
BMC Medical Ethics , 2012, DOI: 10.1186/1472-6939-13-34
Abstract: Background Research ethics guidelines are essential for conducting medical research. Recently, numerous attempts have been made to establish national clinical research documents in the countries of the Middle East. This article analyzes these documents. Methods Thirteen Arab countries in the Middle East were explored for available national codes, regulations, and guidelines concerning research ethics, and 10 documents from eight countries were found. We studied these documents, considering the ethical principles stated in the Declaration of Helsinki, the Council for International Organizations of Medical Sciences (CIOMS) guidelines, and the International Conference of Harmonization - Guidelines for Good Clinical Practice (ICH-GCP). Our paper comprises a complete list of protections, such as confidentiality, informed consent, ethics committees, and others. Results This study found different levels and kinds of research ethics regulations and guidelines in the countries examined. Two groups can be distinguished: the countries in the first group have one or more research ethics regulations or guidelines, while the countries in the second group have not yet established any. Most of the documents showed various degrees of deficiencies in regard to ethical protection. The majority of the documents that were examined refer to one or more international documents on biomedical research ethics. Conclusions Recently, a lot of efforts have been made in many countries in the Middle East. However, compared with international documents, most of the research ethics documents in use in this region demonstrate numerous deficiencies. As it relates to these documents, extensive differences could be observed in regard to development, structure, content, and reference to international guidelines.
Simulation of Unsteady Water Film Flow on Pelton Bucket  [PDF]
Shen Na
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.54B010
Abstract: In order to simulate the complicated unsteady flow in Pelton bucket, it is necessary to apply the animated cartoon approach. In this paper, a free jet and the inner surface of a bucket is described by boundary fitted grid (BFG) with non-orthogonal curvilinear coordinates. The water flow is discretized in space and time for CFD (computational fluid dynamics). The moving grids of water film are successfully projected onto the bucket’s inner surface by a projection algorithm. The visualization result of the jet landing on bucket’s surface and the unsteady flow in the rotating buckets in 3D verifies the effectiveness of the proposed method.
China’s Forensic System: Critical Comments on the “Latest” Flaw  [PDF]

Chinese Studies (ChnStd) , 2014, DOI: 10.4236/chnstd.2014.33013
Abstract: The article will critically examine the fundamental flaws that have been newly discovered from the “latest” case studies. In recent decades, numerous miscarriages of justice have occurred in China mainly due to the insufficient or improper use of forensic evidence. Comments on the “latest” flaw will start from an overview of the notorious wrongful conviction in Case ZHANG Gaoping and ZHANG Hui whose exonerations in 2013 were based on the proper use of forensic techniques such as DNA testing. The case highlights the injustice that results when forensic evidence is ignored in favour of wrongful confessions extorted under police torture. It has been suggested that China’s several waves of forensic science reform cannot lead the current forensic identification to objective, fair or reliable forensic evidence. The “latest” founded flaw entrenched in its forensic system failed to be solved by technical, financial, administrative or legal progress only. In essence, the 2005 reform on forensic identification is flawed to its core, albeit being recently identified. This is primarily because in law forensic experts inside police can conduct identification to provide forensic evidence on cases investigated by police, which cannot ensure necessary check or balance to prevent or reduce forensic errors in practice.
