    The Nile River morphology has changed in the last century, due to the geological, topographical and climatological conditions, as well as due to the human impacts. The main focus of the present study is to detect the surface morphological changes in the first and second Nile River reaches (south of Egypt). For this purpose, several Landsat images acquired at different dates are utilized and analysed based on Remote Sensing (RS) and GIS techniques. Different satellite-derived indices including Normalized Difference Water Index (NDWI), Water Ratio Index (WRI) and Automated Water Extraction Index (AWEI) are applied to generate the (land-water) maps from Landsat data and to create the maps of changes in order to detect the changes in the water surface areas. The results indicated high performance of NDWI in generating the (land-water) maps and creating the maps of changes in both studied reaches of Nile River. For the first reach, NDWI has the highest overall accuracy (about 99.23%) and the lowest absolute error when applied for surface change detection. For the second reach, the NDWI index gave an overall accuracy of 99.13% which indicate the effectiveness and superiority of this index in detecting the surface morphological changes. Moreover, the results for the first reach of the Nile River showed a slightly change in the water surface area during the period 1984–2011. The Nile River in the considered reach lost about 2.3% of its surface area. Meanwhile, the results for the second reach indicated an intense decreasing in the water surface area in the period 1984–2010 (about 13% of the water area in the year 1984), and the utmost of this decreasing occurred over the period from the year 2005 to the year 2010 (about 8.3%).

    Ocular surface disorders (OSD) are frequently encountered in critically ill unconscious patients due to the loss of normal ocular protective mechanisms. in addition to the drawback effect of mechanical ventilation & the use of sedations which leads to decrease tear production and increase evaporation due to eye lid opening, may progress to microbial keratitis and vision defect. Unfortunately, this common problem is underappreciated by ICU clinicians, who usually focused on the management of organ failures, and eye care becomes a side issue. Eye care guidelines and protocols have been developed for increasing eye care implementation in intensive care units. However, the guidelines lack consistency in assessment or intervention methodology. The study aim was to examine the effect of designated eye care protocol on prevention of ocular surface diseases (OSD) among intensive care units (ICU) patient. Methods: To achieve this aim A quasi experimental/interrupted timeseries design with no...

    Background: Diabetes mellitus has increased the risk of more complications. One complication that often occurs is peripheral vascular diseases and decreased foot perfusion of patients by causing endothelial and smooth muscle cell dysfunction in peripheral arteries. Buerger’s exercise is a simple intervention for improving the peripheral circulation of patients with Diabetes mellitus. Therefore, Aim of the study was to evaluate the effect of Buerger-Allen Exercise on improving lower extremities perfusion among patients with type 2 Diabetes Mellitus. Study design: A quasi experimental design was utilized to achieve the aim. Setting: This study was conducted at medical words affiliated to Ain Shams University Hospital; Egypt. Sample: A Purposive sample of 70 patients. Procedure: data were collected using three tools as follow:1-Structured Interview Questionnaire, 2- patient’s medical history and clinical variables tool and 3- Peripheral Circulation Assessment Tools. Results: there was...

    Background: Dysphagia is one of the major post-stroke complications that can severely damage patient's quality of life and even endangers patients’ lives. Shaker exercise is one of the indirect methods, behavioral swallowing techniques, may increase the swallowing speed and sensitivity. The aim of the study was to evaluate the effect of Shaker exercise on dysphagia level among patients with cerebral vascular stroke. Study design: A quasi-experimental design was utilized to achieve this aim. Setting: This study was conducted at Neurology Ward, Stroke ICU and Intermediate Neurological ICU affiliated to Ain Shams University Hospital, Cairo. Sample: A purposive sample included 68 patients. Tools of data collection: Data were collected using three tools: 1- Structured Interviewing Questionnaire, 2- Clinical data tool, 3- Gugging Swallowing Screening (GUSS) scale. Results: There was a highly statistical significance difference in GUSS score of dysphagia level among patients pre and po...

    Context: Nursing is striving to build a knowledge base that supports professional practice and improves the quality of care. Aim: This study aimed to evaluate the effect of self-care management guidelines on nursing-sensitive patients' outcomes after permanent pacemaker implantation. Methods: A quasi-experimental design was utilized in this study. A purposive sample of 50 patients admitted to the cardiac catheterization unit at Ain Shams University Hospital after permanent pacemaker implantation during their follow up visit. They are divided into two matched group study and control groups. Their mean age ±SD was 45.37±5.76, and 48.75±4.27 successively. Patient socio-demographic characteristic and medical data sheet, self-care management level assessment scale, and nursing-sensitive outcomes measuring scale were utilized to achieve the study aim. Results: The study results revealed positive outcomes for patients of the study group compared to the controls and their pre-implementa...

    Context: Post-cardiothoracic surgical chest tube removal (CTR) is considered a painful technique and one of the most painful patients' experiences in the intensive care unit. Painkillers are the most prevalent method to relieve the pain, but the patient may not respond well and achieved complete relaxation. Regardless of scientific advances, no efficient action is possessed to decrease pain and anxiety because of it. Aim: This study aimed to investigate the efficacy of cold application and breathing exercises on pain and anxiety levels following chest tube removal. Methods: A quasi-experimental design (one group pre/post-test) was utilized to achieve the aim. This study was conducted in the Intensive Care Unit at the Cardio-Thoracic Academy Affiliated to Ain Shams University Hospital, Cairo. A Purposive sample included 60 patients undergoing cardiothoracic surgical procedures and having at least two chest tubes in place. Data were collected using three tools; a structured interv...
