引用

Journal of Biosciences and Medicines 2023年第12期11卷 275-286页

作者： Katrel-Nada AlAlawneh Ruaa ibrahim Qasim Mhaidat mohammad Suliman Ahmad Rababah Hajar Ayasreh Eyad Altamimi Department of Pediatric Faculty of Medicine Jordan University of Science and Technology Irbid Jordan Faculty of Medicine Jordan University of Science and Technology Irbid Jordan

Background: The COVID-19 pandemic emerged unexpectedly, impacting millions worldwide and, though waning in many regions, remains a significant concern. This study focused on understanding COVID-19’s clinical presentation, disease progression, and outcomes among hospitalized pediatric patients. Additionally, it sought to investigate the impact of concurrent chronic medical conditions on disease severity. Methods: Conducted retrospectively between September 2020 and December 2021, this study observed pediatric patients (below 18 years) hospitalized with confirmed COVID-19 at an Irbid, Jordan tertiary healthcare center. Patients meeting inclusion criteria, including a positive nasal swab PCR test and hospitalization need, were analyzed. Epidemiological and clinical data were collected and segregated into two groups (A and B) based on the presence of chronic conditions. Comparative analysis encompassed presentation, disease trajectory, and outcomes between these groups. Results: Among 451 tested positive patients, 112 were included in the study. Significant differences emerged between the two pediatric groups hospitalized for COVID-19. Those with concurrent chronic illnesses exhibited heightened symptom severity—fever, dyspnea, fatigue—and a higher incidence of abnormal chest radiographs, often requiring intensive care and experiencing elevated mortality rates. Conclusion: This study underscores the criticality of prioritizing COVID-19 management strategies for pediatric patients with pre-existing chronic medical conditions. The findings highlight the increased vulnerability and poorer outcomes experienced by this subgroup, emphasizing the necessity for tailored interventions and focused care approaches.

作者： Dalia El Nahhal ibrahim El-Nahhal Husam Al Najar mohammad Al-Agha Yasser El-Nahhal Faculty of Health Sciences Islamic University of Gaza Gaza Strip Palestine Université de Toulon Toulon France Department Environment and Earth Science Faculty Science Islamic University of Gaza Gaza Strip Palestine

Effects of wastewater discharge on the coastal area in Gaza strip Palestine are not fully investigated. This study investigated the effect wastewater discharge of the physical and chemical properties of marine water in the coastal area over a period of 2 year. Sea water and sediment samples were collected from about 20 different sites. The water and the sediments were collected wastewater/sea water mixing zone at depth 0, 2.5 and 5 m water column depth at a direct wastewater discharging pipe line from different location and similarly from other locations. Water temperature T, electric conductivity (EC), dissolved oxygen (DO), pH, total dissolved solid (TDS) and salinity were determined for water samples using field equipment such as pH-meter, DO meter, TDS-/ and EC-meter. On the other hand, NO3-, SO42-, PO43- were determined in the laboratory using chemical methods, details are described in materials and method section. Results showed average and standard deviation of T, EC, DO, pH, TDS and salinity were 22.02°C ± 4.1°C, EC: 58.41 ± 4.8 ms/cm;DO: 6.96 ± 1.8 mg/L;pH: 7.69 ± 0.37;TDS: 30.51 ± 3.29 and salinity 4.39 ± 0.12 (%);whereas, average and standard deviation of NO3-: were 299.8 ± 204.1 mg/L;SO42-, 5736.9 ± 817.1;and PO43-: 164.35 ± 120.7 mg/L. The measured values indicate significant differences due to high value of standard deviation of some measured parameters. This indicates the influence of wastewater discharge in sea water as shown inside the manuscript in the appropriate section. The study recommends efficient treatment of wastewater and reuses it for agricultural purposes instead of discharging it in sea.

The purpose of this study is to explore Jordanian nurses’ knowledge and attitudes regarding pain assessment, and barriers to intervention at different hospitals representing health care sectors in Jordan. A descriptive cross-sectional design was used in this study utilizing self-administered questionnaires to collect data from nurses working in public, University-affiliated, and private hospitals located on the north, mid, and south of Jordan using Nurses’ Knowledge and Attitudes Survey Regarding Pain, (n = 439). The mean of total correct answers on the 32 knowledge questions was 13.39 (SD = 4.31). Nurse-related barriers to effective pain management include patient history of alcohol abuse or drug addiction, and nursing staff reluctant to contact physician for analgesic order. Nurses working in surgical units, employed at private hospitals, holding a master degree, or who attended educational course or program scored significantly higher than other nurses. The results demonstrated knowledge deficit and attitude and that nurses underestimated and undertreated patients’ pain. Serious efforts should be taken in nursing schools and hospitals to prepare nurses and equip them with comprehensive knowledge tools to assess and manage pain appropriately.

Journal of Biomedical Science and Engineering 2016年第4期9卷 226-244页

作者： Ayman Yousif ibrahim mohammad Qasim Mehdi Abbas Omar Abbas Abdulrahman Alashkar Kh. H. Haider Department of Basic Sciences SRC Al-Qassim KSA

More than two decades of in vitro experimentation supported by the data from experimental animal studies in both small as well as large experimental animal models have culminated into multiple clinical studies worldwide to assess their regenerative potential. Although the data generated from these studies have only met with cautious response from the researchers, efforts are still underway with the hope to refine the different aspects of cell-based therapy approach to develop it into an effective routine therapeutic intervention. Besides others, search for a cell type with optimal characteristics remains an area of intense research. Pluripotent stem cells in general, and induced pluripotent stem cells in particular have gained special attention of researchers due to their ability to adopt a morphofuntionally competent phenotype. They are being considered as surrogate embryonic stem cells albeit without moral and ethical issues of availability and having better immunological acceptability. We provide a head-to-head comparison of ESCs and iPSCs and an overview of stem cell therapy approach converging on the observed advantages of pluripotent stem cells during pre-clinical and clinical studies.

Open Journal of Animal Sciences 2018年第1期8卷 27-38页

作者： Yaser Fazel Masoud Asadi Fozi Ali Esmailizadeh Fatemeh Fazel Ahmad Massoud Niazi Shahpoor Rahmati mohammad ibrahim Qasimi Department of Animal Science Faculty of Veterinary Kabul University Kabul Afghanistan Department of Animal Science Faculty of Agriculture Shahid Bahonar University of Kerman Kerman Iran Faculty of Veterinary Ferdowsi University of Mashhad Mashhad Iran Department of Clinic Faculty of Veterinary Kabul University Kabul Afghanistan

(Co) variance components and genetic parameters were estimated for milk yield of Iranian Holstein cows. A total number of 68,945 milk test-day records of first, second and third lactations of 8515 animals from 100 sires and 7743 dams originated from 34 herds collected during 2007 to 2009 by Iranian animal breeding center were used. The ASReml computer program was used to analyze the milk test-day records using the random regression procedure. Herd test date (HTD), milking times per day (milking frequency), number of lactations, year of birth, year of calving, age of animal at calving and days in milk (DIM) considered as fixed effects and additive genetic effects and animal permanent environmental effects were considered as the random effects. Additive genetic variance, animal permanent environment variance, residual variance, phenotypic variance, heritability and repeatability were estimated during different months of lactation between 5.7 - 19.6, 15.3 - 27.1, 31.4 - 17.2, 45.8 - 64.83, 0.1 - 0.32 and 0.4 - 0.6, respectively. Genetic correlation and phenotypic correlation were also estimated between months of lactation in range of -0.35 - 0.98 and 0.03 - 0.67, respectively. Genetic correlation and phenotypic correlation both showed the same changing pattern and they decreased as the interval between months of lactation increased.

Objective: To measure the acceptance of a coronavirus disease 2019 (COVID-19) vaccine among the sector of the oil company adult population in Kuwait and assess its determinants. Subjects and Methods: A cross-sectional email study enrolled adults working for Kuwait oil companies (n = 1689;aged ≥21 years). Acceptance of a COVID-19 vaccine was considered if participants selected the options and received the vaccine, definitely or probably will accept vaccination against COVID-19 once a vaccine is available.” A modified Poisson regression was used to investigate the associations and calculate the adjusted prevalence ratios (aPRs) and their 95% confidence intervals (CIs). Results: In total, 92.5% (1563/1689) of the participants were willing to accept COVID-19 vaccines once available. No difference in sex was observed in the willingness to accept a COVID-19 vaccine (92.5 vs. 92%, p 0.5). Responders who believed vaccines in general to have health-related risks were less likely to get vaccinated (aPR = 0.39, 95% CI: 0.35 - 0.44). In addition, participants who received the influenza vaccine were more willing to have a COVID-19 vaccine (aPR = 1.44, 95% CI: 1.31 - 1.58). Acceptance of the vaccine against COVID-19 increased as the self-perceived chances of contracting the infection increased (p Conclusion: Overall, 92.5% of the study participants demonstrated a willingness to be vaccinated against COVID-19. However, we found that public health authorities should address several factors influencing the level of acceptance.
