Application Reality of Knowledge Management Processes Practice in Leaning Resources Centres: Case Study of Learning Resources Centres in Makkah al-Mukarramah Schools in Saudi Arabia
No full textAbstractThis research aims to investigate the reality of applying knowledge management processes and practice in leaning resources centers in all academic stages for males in Makkah al-Mukarramah schools in Saudi Arabia. The significance of this study lies in the provision of with reality checks regarding knowledge management in learning resources centers and also in some impediments resulting from the absence of applying knowledge management processes.In order to achieve this goal, the author uses analytic descriptive method where he applied the research on a sample consists of 41 learning source center secretaries, (15%) of the research community. The author also used a questionnaire formed from four aspects for knowledge dimensions (store, spread, innovation and application). There are 12 phrases or questions listed under each dimension. The obtained data was analysed using (SPSS) to quantitatively demonstrate the relations between the knowledge dimensions and their aspects (store, spread, innovation and application).It was found that knowledge store scored an arithmetic mean (3.65), knowledge application scores a mean (3.57), knowledge innovation scored mean (3.18) and finally Knowledge spread with arithmetic mean score of (2.68). It was concluded that low arithmetic means was due to the lack of availability of appropriate technology and simulating environments inside these learning resources centers, lack of using knowledge management techniques and skills by the secretaries, top management lack of commitment to applying knowledge management processes and practices, mistiness of job descriptions and appropriate training for the secretaries and ignorance of the role of the knowledge management in these learning resources centers
Gastric Dieulafoy's lesion in an elderly man with comorbidities: A case report
Get PDFDieulafoy's lesion (DL) is an abnormal, enlarged (approximately 13mm) and tortious submucosal artery in the gastrointestinal tract wall. Herein, we report a case of recurrent bleeding from a gastric fundus DL in a 59-year-old man who presented with a history of melena associated with dizziness and palpitations. Esophagogastroduodenoscopy revealed a tortuous, dilated vessel in the gastric fundus. Computed tomography angiography revealed an aberrant vessel branching from the celiac artery. Surgery was performed, resulting in complete resolution of the patient’s symptoms. DL is a rare but life-threating cause of gastrointestinal haemorrhage and should be considered in the differential diagnosis
Strongyloides stercolaris infection in a male patient with unusual gastrointestinal tract manifestation and lower limb deep venous thrombosis
Get PDFStrongyloidiasis is an infection caused by the helminthic parasite Strongyloides stercoralis. It is endemic in rural regions of the tropics and subtropics areas. There are between 30 and 100 million an infected persons worldwide. Clinical manifestations of S. stercolaris range from asymptomatic to life-threatening and can be acute or chronic. Symptomatic disease can manifest in skin, the gastrointestinal (GI) tract and/or the respiratory system. Severe and disseminated infection can lead to serious complications. We report a case of strongyloidiasis in a 48-year-old male who presented with gastrointestinal symptoms and developed acute cholecystitis and deep venous thrombosis. Strongyloidiasis is uncommon in Saudi Arabia but must be considered for patients with gastrointestinal symptoms who recently arrived from an endemic area or will begin immunosuppressive therapy
Blood Chemo-Profiling in Workers Exposed to Occupational Pyrethroid Pesticides
No full textThis study investigates the effect of occupational exposure to pyrethroid insecticides on the blood chemo-profiles of workers in the Jazan region. This study was conducted to examine this issue, and workers were divided into exposure groups based on how long they had been employed—from one to two years to more than eight years. Blood samples were analyzed to determine their hematological and biochemical parameters, and their chemo-profiles were assessed by GCMS analysis. Workers exposed for 8+ years had a 3.7 times higher risk of chronic diseases than those exposed for 1–2 years (p < 0.01). Prolonged exposure to pyrethroid pesticides at work is linked to significant changes in blood chemical profiles. While gamma-glutamyl transferase (GGT) levels (p < 0.05) were rather increased by extended exposure times, albumin levels (p < 0.05) showed a significant decrease. These findings suggest re-evaluating and improving workplace safety practices to protect workers from extended pyrethroid exposure
Prevalence of asthma-triggering drug use in adults and its impact on asthma control
Get PDFBackgroundThe use of asthma-triggering drugs (ATDs) is a major factor in poor asthma control (PAC), which can be either uncontrolled or partially controlled. ATDs include angiotensin-converting enzyme (ACE) inhibitors, β-blockers, aspirin, and nonsteroidal anti-inflammatory drugs (NSAIDs).AimsTo measure the prevalence of ATD use in adult asthmatics and their control levels.MethodsThis is a one-year cross-sectional study (starting March 2016). A sample of 173 adult asthmatics (mean age: 44±16 years) was enrolled from five primary care centres in Jeddah city (Saudi Arabia). Asthmatics were clinically diagnosed according to the British Thoracic Society’s asthma guidelines. Chronic obstructive pulmonary disease was excluded by reversibility (i.e., symptom improvement after using asthma drugs). The four questions about asthma control from the Global Initiative for Asthma’s 2016 guidelines were translated to Arabic, photos and names of ATDs available in local pharmacies were collected, and a questionnaire was drafted. The questionnaire was presented to adult asthmatics by medical students during a personal interview. Data were statistically analysed using SPSS.ResultsFifty percent of the adult asthmatics who used ATDs had badly controlled asthma: 31 per cent uncontrolled and 19 per cent partially controlled. Of the patients who took ATDs, 97 per cent had used several ATDs for extended periods of time without any warnings from health professionals. In order of prevalence, aspirin, ACE inhibitors, other NSAIDs, and β-blockers were the most common ATDs used.ConclusionATDs are a major cause of PAC. ATD use is extensive and often goes unnoticed. The present findings highlight the low awareness of health professionals about the undesirable effects of ATDs on asthma control. This problem needs to be resolved by regular and continuous asthma health educational courses. During clinic visits, health professionals should inquire about ATD use, discontinue them, and offer an alternative. This simple action could markedly improve asthma control
