Quality of life of patients with chronic obstructive pulmonary disease in the Gulf Cooperation Council countries
No full textObjective: To assess the health-related quality of life (HRQL) of patients with chronic obstructive pulmonary disease (COPD) in 4 Gulf Council Cooperation (GCC) countries. Methods: We conducted a cross-sectional survey between December 2011 and March 2012 in the following countries: Kingdom of Saudi Arabia (Riyadh, Dammam, and Jeddah), Kuwait, Bahrain, and the United Arab Emirates. The HRQL was measured using the COPD Assessment Test (CAT) and the Chronic Respiratory Disease Questionnaire-Self-Administered Standardized questionnaire (CRQ-SAS). Results: We recruited 120 patients from 6 centers in 4 countries. Their average forced expiratory volume (FEV)1 was 49.3percent (± 13.4) of predicted, and the ratio of FEV1 to forced vital capacity was 0.58 (± 0.11). The average COPD Assessment Test (CAT) score was 20.4 ± 7.6; CAT scores were highest for Riyadh (24.1 ± 7.7); and lowest for Kuwait (18.5 ± 9.2), with no significant difference between the centers. For the CRQ-SAS, the dyspnea domain score was 4.6 ± 1.6, the fatigue domain score was 4.3 ± 1.3, the emotional domain was 4.6 ± 1.2, and the mastery domain was 4.8 ± 1.4. The correlation coefficients of the association between the CAT score and the 4 domains of the CRQ-SAS for all of the centers combined was statistically significant. Conclusion: The CAT and CRQ-SAS revealed that the patients with COPD experienced a moderate to severe impact from the disease, and a considerably compromised quality of life in the GCC countries.Al Moamary Mohamed S, 2012, J Infect Public Health, V5, P159, DOI 10.1016-j.jiph.2012.01.002; Al Moamary MS, 2011, BMC PULM MED, V11, DOI 10.1186-1471-2466-11-21; Al Ghobain M, 2011, ANN SAUDI MED, V31, P129, DOI 10.4103-0256-4947.77485; Al-Haqwi AI, 2010, ANN THORAC MED, V5, P145, DOI 10.4103-1817-1737.65044; Al-Hazzaa HM, 2012, SAUDI MED J, V33, P459; Al-Moamary MS, 2011, SAUDI MED J, V32, P1028; Al-Moamary MS, 2008, SAUDI MED J, V29, P271; Al Moamary MS, 2010, MED PRIN PRACT, V19, P373, DOI 10.1159-000316376; Al Mutairi SS, 2006, RESPIROLOGY, V11, P449, DOI 10.1111-j.1400-1843.2006.00873.x; Al-Riyami AA, 2003, SAUDI MED J, V24, P875; Al-Turki YA, 2006, SAUDI MED J, V27, P700; [Anonymous], 1995, AM J RESP CRIT CARE, V152, P1107; Bednarek M, 2008, THORAX, V63, P402, DOI 10.1136-thx.2007.085456; Behbehani NN, 2004, SAUDI MED J, V25, P585; Bullinger M, 2003, ADV EXP MED BIOL, V528, P113; Chaouachi K, 2009, MED HYPOTHESES, V73, P623, DOI 10.1016-j.mehy.2009.06.016; De Civita M, 2005, PHARMACOECONOMICS, V23, P659, DOI 10.2165-00019053-200523070-00003; Gershon AS, 2010, ARCH INTERN MED, V170, P560, DOI 10.1001-archinternmed.2010.17; Global Initiative for Chronic Obstructive Lung Disease (GOLD), GLOB STRAT DIAGN MAN; Halbert RJ, 2006, EUR RESPIR J, V28, P523, DOI 10.1183-09031936.06.00124605; IBM Corp.

Utilization and responsiveness of the asthma control test (ACT) at the initiation of therapy for patients with asthma: a randomized controlled trial
No full textAbstract Background The aim of this study was to assess the responsiveness of the asthma control test (ACT) to detect changes at the initiation of therapy and its utilization in the initiation of asthma treatment. Methods This study was designed as a randomized clinical trial conducted in a primary care setting. The subjects were asthma patients who had not received controller therapy for at least two months. The patients were randomized into two groups: The Saudi Initiative for Asthma (SINA) group and the Global Initiative for Asthma (GINA) group. Treatment in the SINA group was initiated at step1 when the ACT scores ≥ 20, step 2 when the score between16-19, and step 3 when the score Results Forty-five patients were analyzed in each group. The improvement in ACT score after treatment initiation was significantly higher when the SINA approach was used (2.9 in the SINA group compared to 1.7 in the GINA group (p = 0.04)). The improvement in FEV1 was 5.8% in the SINA group compared to 3.4% in the GINA group (p = 0.46). The number of patients who achieved asthma control at the follow-up visit and required no treatment adjustment was 33 (73.3%) in the SINA group and 27 (60%) in the GINA group (p = 0.0125). Conclusion The ACT was responsive to change at the initiation of asthma treatment and was useful for the initiation of asthma treatment. Trial Registration number ISRCTN31998214</p

No full textOn using Directional Information for Parameter Space Decomposition in Ellipse Detection
No full textIn this paper we use the parametric polar representation to extend the application of edge directional information from circle to ellipse extraction. As a result we obtain a mapping which decomposes the parameter space required for ellipse extraction into two independent sub-spaces and one final histogram accumulator. The mapping includes the tangent of the angle of the first and second directional derivatives. These tangents are computed by considering edge direction at two border points. We show that the use of gradient information for parameter space decomposition avoids the intensive point labelling imposed by geometric constraints used by other approaches

Level Set Gait Analysis for Synthesis and Reconstruction
No full textWe describe a new technique to extract the boundary of a walking subject, with ability to predict movement in missing frames. This paper uses a level sets representation of the training shapes and uses an interpolating cubic spline to model the eigenmodes of implicit shapes. Our contribution is to use a continuous representation of the feature space variation with time. The experimental results demonstrate that this level set-based technique can be used reliably in reconstructing the training shapes, estimating in-between frames to help in synchronizing multiple cameras, compensating for missing training sample frames, and the recognition of subjects based on their gai
Diversity of juvenile fish assemblages in the pelagic waters of Lebanon (eastern Mediterranean)
No full textThe opening of the Suez Canal resulted in the introduction of Indo-Pacific organisms (Lessepsian) to the eastern Mediterranean. Available information on the Levantine ichthyofauna concerns mainly necto-benthic species, while pelagic ones remain mostly uncharacterized. This paper presents a preliminary assessment of biodiversity and its temporal changes on the Lebanese coast (eastern Mediterranean) using species composition and abundance of pelagic communities as indicators. For this purpose, a total of 11,192 fishes, representing 32 species and 19 families were collected with purse seines. Lessepsian species represented 40.9% of the species number in the purse-seine catches but only 0.48% in abundance of individuals and 1.57% in biomass. The families most represented in terms of abundance were the Clupeidae (49.28%), the Engraulidae (41.69%) and the Scombridae (7.01%); in terms of biomass these families represented 56.76, 22.04 and 9.72%, respectively. Abundance and biomass exhibited clear temporal fluctuations with Sardina pilchardus and Scomber japonicus dominating the catches between May and June, and then replaced by Sardinella aurita in July and Engraulis encrasicolus in August. The highest values of species richness (12 species) and diversity indices (H? = 1.37; D = 0.71) were recorded in the last two weeks of June while the lowest values (5 species, H? = 0.26; D = 0.11) were recorded in early August. While Lessepsian fishes represented a minor part in terms of landings, they contributed considerably to the diversity of pelagic fish assemblages in Lebanese water
