Estimating total factor productivity in the Saudi Arabia construction sector

The study aims to estímate the total factor productivity in Saudi Arabia construction sector. Using Cobb Douglas production function. The results showed that that there is a long-run equilibrium relationship between the value of production and the factors of production labour  and capital. The study also showed that the coefficient of labour  is positive with a value of 0.015. While the elasticity of production with respect to capital is about 0.42 the elasticity of production with respect to the capital component is greater than the labour  component and the construction sector in KSA operates in light of decreasing returns to scale (DRS). The results indicates that the construction sector in Saudi Arabia during the coming years will witness a positive growth rate with interest in strengthening the partnership between the government and the private sector in order to develop the construction sector. The study also recommends expanding the production process within the construction sector and moving towards research and development in the field of construction and working to increase investment in the human capital component by training employment and encouragement of investment, in addition to, loans facilitates to the construction sector

A Comprehensive Collection and Analysis Model for the Drone Forensics Field

Unmanned aerial vehicles (UAVs) are adaptable and rapid mobile boards that can be applied to several purposes, especially in smart cities. These involve traffic observation, environmental monitoring, and public safety. The need to realize effective drone forensic processes has mainly been reinforced by drone-based evidence. Drone-based evidence collection and preservation entails accumulating and collecting digital evidence from the drone of the victim for subsequent analysis and presentation. Digital evidence must, however, be collected and analyzed in a forensically sound manner using the appropriate collection and analysis methodologies and tools to preserve the integrity of the evidence. For this purpose, various collection and analysis models have been proposed for drone forensics based on the existing literature; several models are inclined towards specific scenarios and drone systems. As a result, the literature lacks a suitable and standardized drone-based collection and analysis model devoid of commonalities, which can solve future problems that may arise in the drone forensics field. Therefore, this paper has three contributions: (a) studies the machine learning existing in the literature in the context of handling drone data to discover criminal actions, (b) highlights the existing forensic models proposed for drone forensics, and (c) proposes a novel comprehensive collection and analysis forensic model (CCAFM) applicable to the drone forensics field using the design science research approach. The proposed CCAFM consists of three main processes: (1) acquisition and preservation, (2) reconstruction and analysis, and (3) post-investigation process. CCAFM contextually leverages the initially proposed models herein incorporated in this study. CCAFM allows digital forensic investigators to collect, protect, rebuild, and examine volatile and nonvolatile items from the suspected drone based on scientific forensic techniques. Therefore, it enables sharing of knowledge on drone forensic investigation among practitioners working in the forensics domain

Posterior reversible encephalopathy syndrome post stem cell transplantation in sickle cell disease: case series and literature review

IntroductionPosterior reversible encephalopathy syndrome (PRES) is a serious neurological syndrome that may develop following immunosuppressive therapy for stem cell transplantation (SCT). We report 8 patients with sickle cell disease (SCD) who developed PRES, which is likely to be related to immunosuppression.MethodsThis is retrospective cohort analysis of the SCD registry at the King Faisal Specialist Hospital and Research Center (KFSHRC) in Riyadh, Saudi Arabia. Inclusion criteria included all adults SCD patients who underwent SCT from 2011 until 2022. We explored all cases of PRES in patients with SCT. PRES was diagnosed with MRI imaging showing reversible vasogenic cerebral edema associated with neurological symptoms including severe headache, seizures, encephalopathy, delirium, and visual disturbances.ResultsDuring ten years follow-up (2011–2022) we found 8 patients with PRES (age range between 14 to 37 years at diagnosis) PRES occurred 8 to 124 days following SCT in 7 cases and one patient developed PRES 8 months prior to SCT. All patients were on immunosuppressive medications, including tacrolimus, cyclosporine, sirolimus and or mycophenolate mofetil. Headache, seizures, visual hallucinations, confusion, and drowsiness were the most common presenting symptoms. MRI showed abnormalities in the occipital, parietal and frontal lobes in most cases. Recovery was complete in all patients and no recurrences were noted. Two patients had graft versus host disease (GVHD). We compared risk factors for PRES among the 8 cases and 136 SCT in SCD patients who did not develop PRES. There was a significant association between PRES and imaging abnormalities, including previous bi-hemispheric infarctions (p = 0.001), and cerebral microbleeds (CBMs). PRES was strongly associated with presence (p = 0.006), size (p = 0.016) and number (p = 0.005) of CMBs.ConclusionPRES can develop days to weeks following SCT in patients with SCD, and is associated with immunosuppressive therapy, previous bi-hemispheric infarctions and CMB. Prompt recognition and intervention leads to good recovery

General Practitioners, Nurses and Clinical Laboratory Responsibility in Blood Transfusion Monitoring Care Plan and Early Intervention: Review

The objective of this analysis was to assess the responsibilities that physicians, nurses, and clinical laboratory staff play in the process of transfusions of blood and blood products, as well as their ability to intervene promptly in the event that difficulties arise during blood transfusions. It is possible for educational programs concerning blood transfusion to have a favorable impact on the knowledge and performance of physicians, nurses, and clinical laboratory personnel. There is a pressing need to enhance the knowledge and competence of nurses on the unintended consequences that can result from receiving a blood transfusion. An knowledge of the ethical and legal concerns that are involved, the provision of thorough medical management, the utilization of prohaemostatic drugs, and the utilization of essential interventions and strategies to limit blood loss and, as a result, the risk of a subsequent need for blood transfusion are all necessary components of the management of such patients by medical professionals

The Benefit of Health Education Among Population, and the Role of Pharmacist, Nurses and Physicians in Health Education

Education on health and health promotion are two processes that are intertwined and may overlap with one another. The process of defining messages that are intended to enable individuals to take greater control over and improve their own health is referred to as health education. The first thing that has to be done in order to begin the process is to get an understanding of the fundamental cause of the disease process that is considered. There is a significant contribution that the collaboration of physicians, pharmacists, and nurses makes to the provision of patient care and education

Adverse Effect of Local Anesthesia for Disabled Patient During Dental Procedures Assessment: Review

The use of local anesthetic is essential in the field of dentistry. Injections of local anesthesia are performed on a yearly basis in the millions all over the world. These injections are usually considered to be safe invasive procedures. However, there is a possibility of undesirable consequences, which practitioners of dentistry ought to be aware of. The purpose of this scoping review was to offer a comprehensive summary of the published research on the detrimental effects of dental local anesthetic, particularly in patients who have disabilities. There was usually a lack of essential information on side effects, such as the amount or type of anesthetic solution, or the type of needle that was utilized. Because of this, there is a need for research of a high quality on this subject. Last but not least, the literature tends to overrepresent the negative impacts that are rarely observed in actual general practice in the real world

The interventions and outcomes associated with fall-related injuries at tertiary hospitals in the Kingdom of Saudi Arabia: a cross sectional study

Introduction: fall-related injuries are an important health concern around the globe, imposing an immense economic burden. The aim of this study is to evaluate the interventions and outcomes associated with fall-related injuries in a tertiary hospital in the Kingdom of Saudi Arabia (KSA). Methods: a cross-sectional study including 264 patients with fall-related injuries was conducted at the King Khalid Hospital and Prince Sultan Centre for Health Care and other hospitals in Al Kharj from March 01, 2019 to November 30, 2019. The patients were recruited, identified at the point of presentation to the emergency department and followed through the triage, admission and discharge processes. The researchers analysed the participant´s clinical notes on the electronic health record (EHR) to obtain information relevant to the study, including demographic information, the injury patterns and their management. Results: most patients studied were children under the age of 10 (25.7%). The vast majority (96.9%) of patients fell from a height, while the rest fell from a height onto a sharp object. Most of them (90.9%) had experienced no shock symptoms. Upper limb injuries had the highest prevalence (37.8%), followed by lower limb injuries (22.7%), head injuries (19.7%) and skull fractures (13.6%). Invasive surgery, blood transfusions, admission to intensive care (ICU) and thoracostomy (chest tube) were required by 74%, 3%, 3% and 2% of patients, respectively. Conclusion: fall-related injuries may result in invasive surgery, chest drain insertion, or ICU admission, increasing the burden on the healthcare system
