Surveillance and Molecular Identification of Acanthamoeba and Naegleria Species in Two Swimming Pools in Alexandria University, Egypt.

ABSTRACT: BACKGROUND:Swimming in contaminated water was reported to be associated with Acanthamoeba and N. fowleri human infections. The present study was carried out with the aim of isolation and identification of the different species of Acanthamoeba and Naegleria from two swimming pools in Alexandria University. METHODS:Samples were collected from the swimming pools of Alexandria University Stadium and Faculty of Agriculture-Alexandria University during the period from May 2012 to April 2013. RESULTS:Free-living amoebae were prevalent in the collected samples. Molecular characterization confirmed the identity of ten Acanthamoeba isolates and seven Naegleria isolates. Acanthamoeba T3, T4, T5, T11 and T15 genotypes were identified. Acanthamoeba T4 was the most prevalent genotype. CONCLUSION:The relatively high prevalence of Acanthamoeba, especially genotype T4, indicates the presence of a health hazard to swimmers particularly those wearing contact lenses. Naegleria fowleri was not found during the present study.

Project description:BackgroundFood labeling is an important public health tool allowing consumers to make informed and healthy choices. Considering how important it is for consumers to be aware of food labels while choosing healthy foods, this study aims at assessing public awareness, attitude, and practice regarding food labeling in Alexandria Governorate, Egypt.MethodsA cross sectional study using a predesigned interview questionnaire to collect data from 719 adult consumers from both sexes (28.2% males: 71.8% females), recruited from different branches of one of the largest supermarkets in Alexandria.ResultsMore than half of the participants (55.6%) reported reading food labels. The most frequently read information was production/ expiry date (76.8%), product name (68.3%), and ingredients (38.0%) while the least frequently read was nutritional facts (29.9%). More than half of the study sample (50.9%) had low awareness about the content of food labels, nevertheless, having higher scores on awareness about food labels predicted reading practice. Nearly three-quarters of the respondents had average to good food label reading practice. Most respondents (81.8%) had a favorable attitude about food labeling in its present form, however, higher attitude scores did not seem to influence their use of food labels. Being older (β = 0.045, CI; 0.014-0.076, p = 0.005), being female (β = 1.162, CI; 0.541-1.784, p = 0.000), having secondary education or equivalent (β = 1.042,CI; 0.050-2.034, p = 0.040), having university education or beyond (β = 3.090, CI; 2.132-4.048, p = 0.000), and having higher scores on awareness about food labels (β = 1.407, CI; 1.324-1.490, p = 0.000) were significant predictors of reading food labels.ConclusionsMost of the studied consumers had a positive attitude towards food labeling, however, more than half of them had low awareness of food labeling content. Nutritional facts were the least frequently read by consumers. Reading food labels was significantly predicted by having higher education, being older, being a female, and having better awareness.

Project description:BackgroundThe green building industry has significantly impacted the construction market, providing various sustainable solutions for the community. However, conventional green building standards have yet to adequately address occupant health and well-being, leading to challenges with performance. This has caused many businesses to take note of the latest report from the Bureau of Labour Statistics, which indicated that productivity in the US has dropped by the sharpest level since the 1940s. 1 Addressing these issues, organisations like International WELL Building Institute (IWBI) developed WELL Building Rating System (WELL), prioritising occupant health and well-being as critical components for improving performance and avoiding potential vulnerabilities brought about by sickness or pandemics. For this reason, this study will explore how to improve employee productivity within office buildings by bettering their overall health and well-being.MethodsA comprehensive data collection approach was employed in this paper, involving the analysis of office form evolution, and the evaluation of productivity attributes in office spaces. Resulting in identifying the top design-oriented features impacting employee productivity. Data was gathered from traditional office designs, trending successful office buildings, and the WELL Building Rating System to understand the concept of healthy building design.ResultsShowing thermal comfort, ventilation, and natural daylight significantly influence employees' productivity. Implementing conducted design features from WELL achieved an average of 20.2%-35.6% decrease in thermal gain throughout the year, a 20% increase in airflow, an average 2.4%-6.5% decrease in Air temperature, enhanced temperature distribution by 7%, and direct sunlight minimum reduction by 9% in Winter and maximum 21.9% in Spring.ConclusionNew design features in trending successful office buildings positively impact employee productivity. Particularly the outlined features by WELL Building Rating System led to identifying the most influential factors affecting occupant productivity. The results of this study informed recommendations for enhancing productivity in existing office buildings in Alexandria, Egypt.
