Project description:Background: Due to Egypt's strategic location among countries, transportation is one of the most significant development sectors because it plays a major part in today's economy and society and has a large influence on growth and employment. Over the years, the Egyptian General Organisation of Physical Planning (GOPP) has prepared strategic general urban plans in collaboration with local and foreign organisations, including transportation plans. The constant focus of authorities on strategic plans and their inability to implement them on schedule are a major issue. In other words, they always take development from a distant perspective and do not deal with the main problem that exists within cities, as the existing micro-scale transit built environments (MSTBEs) of cities are not ready due to a lack of transit-oriented communities (TOCs), sustainably developed transit supply systems, and mobility hubs. Methods: The "Enhanced MSTBE Phases" methodology is used for the key elements of the study design used in this research, depending on data collection, approvals, techniques, and analysis methods. As a case study, these key elements are in the documentation, analysis, and development of the Muharram Bek El Mowkaf El Gedid Mobility Hub (MBMH) and the 800 m radius around it. Results: The results indicate that Enhanced MSTBE Phases led to the establishment of the MBMH and the 800 m radius surrounding it as a sustainable MSTBE in Alexandria, Egypt, which is chosen as the case study. Conclusions: The development of this MSTBE is a catalyst for future effects that will have a long-term impact on meso-scale and, ultimately, macro-scale transit built environments.

Project description:BackgroundThis study was performed to determine the prevalence and to identify precisely Toxocara spp., which infects feral cats in Alexandria, Egypt based on morphological and molecular approaches.MethodsThis cross-sectional study was carried out on 100 feral cats trapped from different areas of Alexandria during 2018. Adult male and female worms were recovered from small intestinal contents after euthanasia and dissection of cats. Distinct morphological features were initially determined using available keys, and then after amplification and sequencing of the mitochondrial NADH dehydrogenase subunit 1 (nad1) gene was carried out and phylogenetic trees were constructed.ResultsForty out of 100 cats were infected with Toxocara spp. Intensity of infection ranged from 1 to 9 worms/cat, with a mean of 2.27±1.6. All isolates were confirmed as T. cati based on morphological features and the sequence of nad1 gene. Results of the current study clearly show that Egyptian T. cati isolate examined herein is genetically similar to those recorded in other countries.ConclusionThe current work revealed high prevalence of T. cati in feral cats in the study area. This is the first genetic study that confirms T. cati from feral cats in Egypt. In addition, it demonstrated the suitability and need of genetic markers such as nad1 for identification of Toxocara spp. Furthermore highlights the public health importance of T. cati in Egypt.

Project description:BackgroundGround beetles (Carabidae, Coleoptera) are one of the most species-rich and well-studied insect families. However, the number of published datasets is disproportionately low against the biodiversity of this group. According to GBIF, only a fifth of the percentage of all published data covers ground beetles. This article describes a sampling-event dataset providing primary data on ground beetles collected in urban and suburban habitats in Kaluga, a typical central Russian city. We surveyed habitats of different land-use types and the extent and intensity of anthropogenic influence: yards, gardens, quarries, small urban woodlands, grasslands and riparian habitats. Carabids were collected by pitfall traps during most of the vegetative season (mostly from late April - early May to at least early October) for 13 seasons between 1994 and 2015. In total, the dataset contains 189 carabid species and 79,091 specimens. The dataset provides information about species composition and abundance, habitat distribution, seasonal and long-term dynamics of carabid beetles in environments of different degrees of urbanisation.New informationThis dataset is the first sampling-event dataset about carabids in various urban habitats published through GBIF.

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:Antimicrobial stewardship isn't strictly observed in most Egyptian hospitals, raising antibiotic resistance. Epidemiology of Egyptian MRSA isolates, or associations with resistance to other antibiotics remain largely unknown. We identified MRSA genotypes in Alexandria Main University Hospital (AMUH) and investigated rates of moxifloxacin resistance, an alternative MRSA treatment, among different genotypes. Antibiotic susceptibility of 72 MRSA clinical isolates collected in 2015 from AMUH was determined by disc diffusion and broth microdilution. spa- and Staphylococcal Cassette Chromosome mec (SCCmec) typing were performed; with multi-locus sequence typing conducted on isolates representing major genotypes. Resistance to moxifloxacin, levofloxacin and ciprofloxacin were 69%, 78% and 96%, respectively. spa type t037 (57%) was commonest, followed by t127 (12.5%), t267 (8%) and t688 (6%). SCCmec III predominated (57%), all of these were moxifloxacin resistant and 97.6% t037 (ST241). SCCmec IV, IV E and V represented 15%, 7% and 11% of the isolates, respectively, 79% of these were moxifloxacin susceptible and of different spa types. t127 (ST-1) was associated with SCCmec V in 56% of the isolates, mostly moxifloxacin susceptible. Moxifloxacin resistance was high, most resistant isolates belonged to t037 and SCCmec III, suggesting local dissemination and antibiotic pressure. We recommend caution in treating MRSA infections with moxifloxacin.

Project description:BACKGROUND:Pneumonia among under-five children constitutes a major public health concern. Studies examining risk factors for pneumonia in Egypt are limited. AIM:To identify risk factors of pneumonia among under-five children in Alexandria, Egypt. METHODS:An observational case-control study was conducted over a 5-month period (September 2017-January 2018) in three main pediatric hospitals in Alexandria. A predesigned questionnaire was used to interview 660 mothers of under-five children (330 pneumonia cases and 330 control). The questionnaire included potential risk factors for pneumonia which were categorized into child-related factors, socio-demographic factors, and environmental factors. RESULTS:The mean age of the children was 23.14 ± 18.61 months with a range of 1-59 months. Nearly two-thirds (58.5%) were boys. Nine factors were found to be independently associated with pneumonia: age ≤ 12 months (OR = 1.925; 95% CI, 1.356-2.733; P < 0.001), male gender (OR = 1.646; 95% CI, 1.162-2.332; P = 0.005), birth order ≥ 4 (OR = 2.154; 95% CI, 1.282-3.617; P = 0.004), low birth weight (OR = 2.562; 95% CI, 1.718-3.821; P < 0.001), prematurity (OR = 2.019; 95% CI, 1.154-3.531; P = 0.014), place of delivery either at home (OR = 5.669; 95% CI, 1.063-30.237; P = 0.042) or at a public hospital (OR = 1.616; 95% CI, 1.131-2.310; P = 0.008), presence of concomitant illness (OR = 1.902; 95% CI, 1.043-3.469; P = 0.036), poor home aeration (OR = 3.586; 95% CI, 1.971-6.522; P < 0.001), and exposure to outdoor air pollution (OR = 2.403; 95% CI, 1.417-4.076; P = 0.001). CONCLUSION:Several risk factors were significantly related to pneumonia among under-five children. Identifying such factors is important for developing interventions to reduce pneumonia burden among under-five in Egypt.

Project description:Carbapenem resistant Acinetobacter baumannii is a major global concern, especially in countries of the Middle East and North Africa, where the antibiotic resistance rates are on the rise. The aim of this study was to study the genomic characteristics and antimicrobial susceptibility profile of thirty-six multidrug resistant A. baumannii clinical isolates obtained in hospitals from Alexandria, Egypt. Antibiotic resistance rates were estimated by determination of Minimum Inhibitory Concentrations. Carbapenemase genes, other antibiotic resistance genes and virulence factors were then screened by the use of Whole Genome Sequencing. Isolates were also subjected to Multi Locus Sequence Typing (MLST) using the Pasteur Scheme and to core genome MLST to study their clonal relatedness. In addition, plasmid analysis was performed by the use of a commercial kit and S1- Pulsed Field Gel Electrophoresis, and Hybridization experiments with DIG-labeled DNA probes for bla NDM-1, blaPER-7 and bla GES-like were performed to locate these genes. The majority of isolates were resistant to β-lactams (including carbapenems), fluoroquinolones, aminoglycosides and trimethoprim; and some showed resistance to cefiderocol and minocycline. We identified 8 different bla OXA-51-like variants including bla OXA-51, bla OXA-64, bla OXA-65, bla OXA-66, bla OXA-68, bla OXA-91, bla OXA-94 and bla OXA-336; bla OXA-23, bla NDM-1, bla PER-7, bla GES-like and bla ADC-like and other antibiotic resistance genes, some of these genes were within transposons or class 1 integrons. Multiple virulence factors responsible for adherence, biofilm production, type II and type VI secretion systems, exotoxins, exoenzymes, immune modulation and iron uptake were observed and 34 out of 36 isolates showed motility. Thirty-five out of 36 isolates clustered with International Clones 2, 4, 5, 7, 8 and 9; and 9 STs were identified including ST570, ST2, ST600, ST15, ST113, ST613, ST85, ST158, ST164. Plasmids ranging in size from 1.7 to 70 kb were found; bla NDM-1 and blaPER-7 genes were located in the chromosome and bla GES-like genes were simultaneously located in the chromosome and in a plasmid of 70kb. In conclusion, this study revealed a wide spectrum of antibiotic resistance genes and a variety of lineages among A. baumannii isolated in hospitals from Alexandria, and highlights the importance of investigating the molecular epidemiology to control the spread of multi-drug resistant isolates.

Project description:The present research aims to evaluate the impact of industrial processes and anthropogenic activities on the beetle Pimelia latreillei inhabiting the polluted site at Zawya Abd El- Qader, Alexandria, Egypt. Beetles were collected from the vicinity of five factories. The genotoxic effects of environmental exposures to industrial heavy metals were monitored using a broad range of assays, including energy-dispersive X ray microanalysis and X-ray diffraction (SEM and EDX)), qRT-PCR gene expression assay, micronuclei formation, and transmission electron microscope (TEM). Energy dispersive X-ray microanalysis for the soil and testicular tissues of beetles collected from the polluted site revealed a higher percentage of heavy metals than the beetles collected from the reference site (Sidi Kirier, Alexandria, Egypt). To analyze/monitor genotoxicity in P. latreillei sampled from the polluted site, the transcription levels of levels of heat shock proteins (Hsps) and accessory gland seminal fluid protein (AcPC01) in testicular tissues were recorded. The incidence of micronuclei (MN) formation in the testicular cells was also observed. Quantitative RT-PCR (RT-qPCR) analysis was carried out to detect the changes in the gene expression of the aforementioned proteins. Genes encoding heat shock proteins (Hsp60, Hsp70, and Hsp90) were significantly overexpressed (> 2-fold) in specimens sampled from the polluted site; however, AcPC01 gene expression was under-expressed (<1.5-folds). The incidence of MN was significantly increased in specimens sampled from the polluted site. Ultrastructure anomalies (nuclear and cytoplasmic disruption) were also observed in the testicular cells of the beetles sampled from the polluted site compared to those sampled from the unpolluted site. Our results, therefore, advocate a need for adequate measures to reduce increasing environmental pollution in the urban-industrial areas.

Project description:The COVID-19 pandemic has brought huge challenges to sustainable urban and community development. Although some recovery signals and patterns have been uncovered, the intra-city recovery process remains underexploited. This study proposes a comprehensive approach to quantify COVID-19 recovery leveraging fine-grained human mobility records. Taking Wuhan, a typical COVID-19 affected megacity in China, as the study area, we identify accurate recovery phases and select appropriate recovery functions in a data-driven manner. We observe that recovery characteristics regarding duration, amplitude, and velocity exhibit notable differences among urban blocks. We also notice that the recovery process under a one-wave outbreak lasts at least 84 days and has an S-shaped form best fitted with four-parameter Logistic functions. More than half of the recovery variance can be well explained and estimated by common variables from auxiliary data, including population, economic level, and built environments. Our study serves as a valuable reference that supports data-driven recovery quantification for COVID-19 and other crises.
