Effects of Honey on Oral Mucositis among Pediatric Cancer Patients Undergoing Chemo/Radiotherapy Treatment at King Abdulaziz University Hospital in Jeddah, Kingdom of Saudi Arabia
No full textOne of the most common complications of cancer chemotherapy is oral mucositis. This study evaluates the therapeutic effects of honey with the focus on grade III and IV oral mucositis, reduction of bacterial and fungal infections, duration of episodes of oral mucositis, and body weight in pediatric leukemic patients undergoing chemo/radiotherapy. This is an open labeled randomized controlled study conducted at our hospital on 40 pediatric cancer patients undergoing chemo/radiotherapy. All the 40 patients included in this study experienced a sum total of 390 episodes of fever and neutropenia associated with oral mucositis. A significant reduction of oral mucositis, associatedCandida, and aerobic pathogenic bacterial infections was noted in patients in the honey treatment group. Also, there is a significant decrease in the duration of hospitalization for all those in the treatment group combined with a significant increase of body weight, delayed onset, and decreased severity of pain related to oral mucositis. Complications of oral mucositis can be tremendously reduced by the topical application of local Saudi honey and honey should be used as an integrative approach in prophylaxis and treatment of chemo/radiotherapy-induced oral mucositis in pediatric cancer patients. Further research is needed to elucidate and better understand the underlying mechanism.</jats:p

Efficient performance in economic diversification policy in Iraq (Benefiting from the lessons of sample countries)
No full textEconomic diversification is a challenge for most developing countries, especially for low-income countries and small or commodity-dominated economies. Economic diversification is closely related to the structural transformation of its economies and the achievement of a higher level of productivity resulting from the introduction of knowledge and skills within the economic sectors, so the research seeks to benefit the Iraqi economy from the lessons of sample countries through industrial and knowledge transformation, and not relying on a specific economic resource, as innovation in economic diversification is of great importance in increasing the added value of the sectors used because of its significant effects in reducing production costs and increasing exports, which contribute to achieving economic development. It requires an effective economic policy to support development in Iraq, and fix the failures in policies aimed at financing the diversification process and reducing costs
Factors Associated with the Severity of Covid-19 in Jeddah, Saudi Arabia – A Retrospective Cohort Study
No full textIntroduction: SARS-CoV-2 caused a major outbreak in December 2019 in Wuhan, China. The disease was declared a pandemic in March, 2020 by the World Health Organization (WHO). The disease caused over 8 million confirmed cases and almost 450,000 deaths. Our study aims to explore all risk factors associated with Covid-19 severity among hospitalized patients. Methods: Hospital-based records are retrospectively collected from a cohort of admitted RT-PCR COVID -19 positive patients aged 18 years and older. ISARIC data collection form was used to collect all potential risk factors. Logistic regression is used to calculate crude and adjusted OR. Statistical analyses will be done using STATA v.13.0. Results: 224 hospitalized Covid-19 patients were collected. The mean age was 48.6 (SD±15.1) years old. Patients were significantly older among the severe to critical cases than among the mild to moderate cases with a mean of 53.2 (SD±13.4) vs 43.4 (SD±15.2) (p<0.05). Having DM was more prevalent among the severe to critical cases than mild to moderate cases (69.9%) vs (30.2%). Having a history of DM (OR=3.18) was significantly associated with a severe form of Covid-19, along with other significant risk factors (<0.05): having a higher BMI (OR=2.04), fever (OR= 3.37), sore throat (OR=0.11), shortness of breath (OR=2.68), RR (OR=1.19), lymphocyte count (OR=0.59), WBC count (OR=1.38) and viral pneumonia (OR=10.03). Conclusion: Older age, being diabetic, dyspnea, decreased lymphocyte count, increased WBC and acquiring viral pneumonia can all significantly predict Covid-19 disease progression
Translatability Of Arabic Fixed Expressions In Three Novels Into English Using Neural Machine Translation
No full textArabic fixed expressions (AFEs) have a symbolic figurative meaning that cannot be predicted from the individual components or the literal meanings of constituent parts. Many users nowadays rely on NMT systems to translate AFEs since these systems became an essential part of the process of translation. However, Neural Machine translation (NMT) creates a sort of difficulty and challenge to those who do not have enough experience in the translation of fixed expressions like proverbs and idioms. These translation systems might create a gap between Source Language (SL) and Target Language (TL). The study investigates the syntactic structure of the Arabic Fixed Expressions (AFEs), which allows a high level of accuracy to be achieved in its translation using selected Neural Machine Translation (NMT) systems. Also, this study seeks to identify the most efficient system to render the meaning of the (AFEs) extracted from the the three novels. Moreover, the study examines problems that hinder NMT systems when translating Arabic fixed expressions into English. In order to achieve the aim of this study, the researcher select samples of Arabic proverbs and idioms from three literary texts Banat AlRiyadh (Girls of AlRiyadh) by Rajaa Alsanea, Mawsim al-Hijrah ilâ al-Shamâl (Season of Migration to the North) and by Tayeb Saleh, and Suqut al-lmam (The Fall of the Imam) by Nawal El Saadawi) to be translated automatically by NMT systems in order to measure and evaluate the accuracy level of these software in particular. The researcher inserts texts containing a certain number of these expressions and analyze the obtained results after these systems translate the texts from Arabic into English
Association of IFNAR2 rs2236757 and OAS3 rs10735079 Polymorphisms with Susceptibility to COVID-19 Infection and Severity in Palestine
No full textThe clinical course and severity of COVID-19 vary among patients. Tis study aimed to investigate the potential correlation between the gene polymorphisms of the interferon receptor (IFNAR2) rs2236757 and oligoadenylate synthetase 3 (OAS3) rs10735079 with the risk of COVID-19 infection and its severity among Palestinian patients. Te study was conducted between April and May 2021 on 154 participants who were divided into three groups: the control group (RT-PCR-negative, n = 52), the community cases group (RT-PCR-positive, n = 70), and the critically ill cases (ICU group; n = 32). Te genotyping of the investigated polymorphisms was performed using amplicon-based next-generation sequencing. Te genotypes distribution for the IFNAR2 rs2236757 was signifcantly diferent among the study groups (P = 0.001), while no statistically signifcant diferences were found in the distribution of genotypes for the OAS3 rs10735079 (P = 0.091). Logistic regression analysis adjusted for possible confounding factors revealed a signifcant association between the risk allele rs2236757A and critical COVID-19 illness (P < 0.025). Among all patients, those who carried the rs2236757GA were more likely to have a sore throat (OR, 2.52 (95% CI 1.02–6.24); P = 0.011); the presence of the risk allele rs2236757A was associated with an increased risk to dyspnea (OR, 4.70 (95% CI 1.80-12.27); P < 0.001), while the rs10735079A carriers were less likely to develop muscle aches (OR, 0.34 (95% CI 0.13–0.88); P = 0.0248) and sore throat (OR, 0.17 (95% CI 0.05–0.55); P < 0.001). In conclusion, our results revealed that the rs2236757A variant was associated with critical COVID-19 illness and dyspnea, whereas the rs10735079A variant was protective for muscle aches and sore throatTe authors would like to thank all the study participants
