Abstract	Potentially toxic elements can enter the environment through natural and anthropogenic processes, with the latter considered the primary contributor. Road dust samples from two industrial parks on the island of Trinidad were investigated for heavy metal content, and the pollution status, potential health risks, and source apportionment were evaluated. Samples were acid-digested and analysed by flame atomic absorption spectroscopy. The average levels of cadmium, chromium, copper, manganese, nickel, lead, and zinc in road dust at the Frederick Settlement Industrial Park were 1.14 μg/g, 15.13 μg/g, 66.42 μg/g, 768.49 μg/g, 37.95 μg/g, 55.90 μg/g, and 573.04 μg/g, respectively, while average concentrations at the O'Meara Industrial Park were 1.20 μg/g, 16.97 μg/g, 42.72 μg/g, 482.65 μg/g, 21.12 μg/g, 136.77 μg/g, and 358.70 μg/g, respectively. Contamination assessments evaluated both Fredrick Settlement and O'Meara as typically uncontaminated to moderately polluted, with the overall ecological risk deemed low at all locations. Hazard index values at all sampling areas were lower than 1, indicating no potential non-carcinogenic risks to children or adults, while the carcinogenic exposure risks for cadmium, chromium, and nickel were considered low. Principal component analysis and cluster analysis revealed two main sources of contamination for Fredrick Settlement, and three main sources for O'Meara. Based on the groupings obtained, the presence of potentially toxic elements was attributed primarily to specific anthropogenic activities within the industrial parks, with lesser contributions from vehicular-related sources.

Abstract	The increase in urbanisation and industrialisation have contributed significantly to elevated concentrations of heavy metals in soils. The eventual uptake of heavy metals by agronomic crops could potentially affect human health based on consumption patterns in various regions of the globe. This study investigated the potential health risks to consumers of dried legumes in a small island developing state that rely primarily on the importation of those crops from major producers. Several varieties were analysed for selected heavy metals in which Cd and Pb were not detected and Cr was only present in certain legumes. The concentrations of Cu, Mn, Ni, and Zn were all below the established World Health Organisation (WHO) maximum permissible limit (MPL) and the target hazard quotient (THQ) and hazard index (HI) values were below one for all samples, suggesting no non-carcinogenic risk to consumers.

Abstract	Within recent times, heavy metal contamination in rice (Oryza Sativa) has been of growing concern particularly due to its implications on human health via consumption. Twenty-one different brands of rice marketed in Trinidad and Tobago were investigated for their heavy metal content (Cd, Cr, Cu, Mn, Ni, Pb and Zn) using Flame Atomic Absorption Spectroscopy. Lead was not detected in any of the samples, while both Cadmium and Nickel were detected in only one sample each at 0.27 and 1.79 μg/g, respectively. The average metal concentrations decreased in the following order: Zinc > Manganese > Copper > Chromium with concentrations ranging from 1.00–4.35, 1.72–29.92, 5.87–43.56 and 0.06–1.16 μg/g, respectively. The target hazard quotient (THQ) and hazard index (HI) values for all samples were less than one, indicating no risk of non-carcinogenic effects to consumers.

Abstract	Background: Migraine is an important healthcare concern that silently affects diverse populations globally. The rising prevalence of migraine affects the quality of life of individuals, the economic burden of a nation, and work productivity. This study was designed to determine the prevalence of migraine in Saudi Arabia. Methodology: A systematic data search was designed, and scientific data were collected from leading databases, including PubMed, The Cochrane Library, Web of Science, Ovid, and Google Scholar. Results: Thirty-six studies, comprising 55061 study participants based on defined inclusion criteria, were statistically analyzed using StatsDirect software. The pooled proportion of migraine in Saudi Arabia among all 36 selected studies was 0.225617 (95% confidence interval (CI) = 0.172749 to 0.28326). The study was grouped into four categories: general population, students (of both genders), studies based on females only, and healthcare professionals in primary health care (PHC). The migraine pooled proportion among all four groups using random effects (DerSimonian-Laird) was 0.213822 (95% CI = 0.142888 to 0.294523), 0.205943 (95% CI = 0.127752 to 0.297076), 0.345967 (95% CI = 0.135996 to 0.593799), and 0.167068 (95% CI = 0.096429 to 0.252075), respectively. Conclusion: The estimated pooled proportion of migraine in Saudi Arabia is 0.225617, which is comparable to or even higher than other parts of the Middle East region. Migraine has a great impact on quality of life, productivity, and economic capacity, and increases the healthcare burden. Early detection and necessary lifestyle measures are necessary to minimize this number.

Abstract	Road dust from the Point Lisas Industrial Estate in Trinidad, West Indies was investigated to determine its heavy metal content and the associated health risks. The average concentrations of Cd, Cr, Cu, Mn, Ni, Pb and Zn were 3.44, 37.69, 58.16, 770.69, 35.61, 68.50 and 342.53 μg/g, respectively. The health risks due to exposure to heavy metals in road dust were assessed based on the US EPA's Health Risk Assessment Model for both carcinogenic and non-carcinogenic effects. The health risk assessment indicated that the ingestion pathway was the main exposure route to heavy metals from road dust; however, HI values suggested no potential health risks to both children and adults. The cancer risks for Cd, Cr and Ni were less than 10

Abstract	Semantic Textual Similarity (STS) is the task of identifying the semantic correlation between two sentences of the same or different languages. STS is an important task in natural language processing because it has many applications in different domains such as information retrieval, machine translation, plagiarism detection, document categorization, semantic search, and conversational systems. The availability of STS training and evaluation data resources for some languages such as English has led to good performance systems that achieve above 80% correlation with human judgment. Unfortunately, such required STS data resources are not available for many languages like Arabic. To overcome this challenge, this paper proposes three different approaches to generate effective STS Arabic models. The first one is based on evaluating the use of automatic machine translation for English STS data to Arabic to be used in fine-tuning. The second approach is based on the interleaving of Arabic models with English data resources. The third approach is based on fine-tuning the knowledge distillation-based models to boost their performance in Arabic using a proposed translated dataset. With very limited resources consisting of just a few hundred Arabic STS sentence pairs, we managed to achieve a score of 81% correlation, evaluated using the standard STS 2017 Arabic evaluation set. Also, we managed to extend the Arabic models to process two local dialects, Egyptian (EG) and Saudi Arabian (SA), with a correlation score of 77.5% for EG dialect and 76% for the SA dialect evaluated using dialectal conversion from the same standard STS 2017 Arabic set.

Abstract	In our emergency department (ED), we found one interesting case that had dramatic deterioration. The patient initially presented with a fever that deteriorated to sepsis, then a septic shock and chest discomfort and finally resulting in an intensive care unit (ICU) admission. He waited more than 6 hours in the waiting area, for a bed in an observation room. Phlebotomy and supportive treatment were provided in the waiting area but maybe it needed more rapid treatment to avoid the serious complications. The case rapidly deteriorated as type II myocardial infarction (MI). Al WAKRA TYPE II MI, is a case report for type II MI developed in ED as complication of prolonged waiting time in overcrowded ED, its simple fever case getting deterioration to sepsis then type II MI after prolonged waiting time in the waiting area of ED to get a bed in the observation room. We aim to report a case of type II MI in ED as rare case developed in overcrowded ED, to put highlight about overcrowded ED and how to manage it to avoid this complication again, also to be aware about pre sepsis presentation in ED with full consideration about sepsis complication and management. It could be considered as a case study for the Quality in overcrowded ED.

Abstract	A field study was conducted at ICAR-Indian Institute of Spices Research, Regional Station, Madikeri, Karnataka during 2018 and 2019 to evaluate elite lines of small cardamom (Elettaria cardamomum Maton) for capsule yield, essential oil constituents, photosynthesis and antioxidant enzyme activities under moisture stress condition. Eight small cardamom lines were selected for the study and were grown under irrigated and moisture stress conditions adopting all the package of practices. Photosynthetic gas exchange, relative water content, total soluble proteins and antioxidant enzyme activities were determined at panicle initiation stage during summer. Yield and essential oil components were recorded after harvest. The results showed that moisture stress significantly reduced the soluble protein content and stomatal conductance in the leaves thereby lowering net photosynthetic rate, thus inhibiting growth and yield. Antioxidant enzyme activities viz. catalase, peroxidase, superoxide dismutase and polyphenol oxidase were significantly influenced by moisture stress. Among the genotypes, IC584058 showed bold capsules, higher and less reduction in yield under irrigated and moisture stress condition, respectively. It is suggested that the soluble protein and antioxidant enzymes in leaves play important role in maintaining cell water content and photosynthetic gas exchange during panicle initiation stage leading to less reduction in yield under moisture deficit condition. The essential oil components of three lines namely IC584058, IC584078 and IC584090 showed drastic variation under moisture stress. Though the α-terpinyl acetate content decreased (P<0.05), the oxygenated monoterpenes significantly increased in stress tolerant genotype IC584058 which influences antioxidant and antimicrobial activities leading to plant adaptive defense mechanism under moisture.
