Abstract:

Aims: Prospective pharmacist’s interventions aimed to improve patient’s knowledge and behaviors to adhere to medications in patients with type 2 diabetes with or without cardiovascular medical conditions in primary health care (PHCs) centers in Nyala city, South Darfur State, Sudan. Methodology and Materials: 300 patients were enrolled for assessing adherence with the Brief Medication Questionnaire (BMQ) in ten PHCs in Nyala city. We assessed patients’ responses to BMQ pre-and post-interventions plan by: complex interventions, humanitarianism and disease outcomes determined by health-related outcomes (SF-36), glycosylated hemoglobin (HbA1c) and blood pressure. Results: BMQ scores have improved significantly in four screens (pre-and post-interventions): regimen [4.6 ± 0.2 to 1.8 ± 0.1; P =

The Impact of Single Low Dose IV Magnesium Sulphate Adjuvant to Ultrasound Guided Transverses Abdominis Plain Block for Control of Postcesarean Pain  [PDF]
Tamer Nabil Abd Elrahman, Mohamed Abdelaziz Youssry
Open Journal of Obstetrics and Gynecology (OJOG) , 2017, DOI: 10.4236/ojog.2017.73029
Abstract: Objective: The aim of this study is to determine the role of preoperative low dose intravenous MgSO4 when given adjuvant to ultrasound guided transversus abdominis plane (TAP) block in augmenting postcesarean analgesic effects and reducing opioid requirements during the first 24 hours. Subjects and Methods: In this prospective, randomized double blind study, a total of sixty full term pregnant women were recruited for the study underwent caesarean section. Thirty patients were assigned to MgSO4 group (A) and another thirty to placebo group (B). Participants in group (A) received 50 mg/kg MgSO4 in 100 ml isotonic saline intravenous (IV) over 20 minutes prior to induction of general anesthesia by 30 minutes while participants in group (B) received 100 ml isotonic saline (placebo) by the same route and over the same duration as control. Results: Visual Analogue Scale (VAS) was analysed within 24 hours postoperatively. The mean pain score at 6 and 12 hours postoperatively was significantly lower in MgSO4 group compared to control group (40.4 ± 5.12 vs 53.6 ± 4.92; 26.1 ± 3.01 vs 35.5 ± 3.98 respectively, p = 0.012, 0.005). Comparing both groups regarding the mean time interval of first rescue analgesia (morphine sulphate) requested by the patients, it was longer in MgSO4 group compared to control group. The total dose of rescue analgesia consumed during 24 hours was analysed and it was significantly higher in control group compared to MgSO4 group (10.1 ± 0.95 vs 6.2 ± 0.87, p = 0.001). Conclusion: We concluded that preoperative low doses (50 mg/Kg) of MgSO4 with general anesthesia combined with ultrasound guided TAP block offer longer postoperative pain free periods thus reducing total opioid consumption. In addition to the safety of the drug to the mother and fetus so we recommend IV MgSO4 as an adjuvant therapy with TAP block.

Open Journal of Anesthesiology (OJAnes) , 2019, DOI: 10.4236/ojanes.2019.94009
Abstract: Background: Anesthesiologists are responsible for the development of pain services in the current era. Hence ideal adjuvants that can be used with bupivacaine for stable intraoperative conditions and prolonging the postoperative analgesia with fewer side effects are being investigated. Opioids, despite useful as adjuvants, are associated with undesirable side effects. Aim of the work: The study was done to compare analgesic efficacy and hemodynamic of intrathecal injection of bupivacaine alone or with fentanyl, clonidine, and neostigmine in lower abdominal surgeries, over the first 24 postoperative hours, in a randomized, double-blind, and clinical trial. Methods: 100 Patients were randomized into four equal groups, 25 patients in each group; Group B patients received 2.5 ml of 0.5% hyperbaric bupivacaine and 0.5 ml of normal saline. Group BF patients received 2.5 ml of 0.5% hyperbaric bupivacaine with (25 mics) of fentanyl. Group BC patients received 2.5 ml of 0.5% hyperbaric bupivacaine with 0.5 ml (75 mics) of clonidine. Group BN patients received 2.5 ml of 0.5% hyperbaric bupivacaine with 0.1 ml of neostigmine (50 mics) and 0.4 ml of normal saline. Intrathecal anesthesia was done with a recording of parameters intraoperative and the post-operative period. Each patient was assessed for hemodynamic parameters and effective analgesia in operation, and presence of complications (nausea, vomiting, sedation and pruritus) visual analogue pain score (VAS) postoperatively by a blinded investigator in the post-anesthesia care unit (PACU) and at 1, 2, 3, 4, 8 12, 18 and 24 h postoperatively. Results: The postoperative analgesia is more effective with group BC (the gold standard) than group B, group BF, and group BN. As regard complications during the study in all groups, complications as nausea, and vomiting were mainly with group BN; hypotension was primarily in group BC. Conclusion: Bupivacaine clonidine, bupivacaine neostigmine, and bupivacaine fentanyl intrathecal anesthesia produced a longer duration of postoperative analgesia after lower abdominal surgery in patients than bupivacaine alone. Bupivacaine clonidine mixture had the most extended period of analgesia, but with hypotension. So bupivacaine fentanyl mixture with moderate duration of analgesia and minimal side effects is most safe for a patient.

Reem Hamad, Ahmed S. Abd Elrahman, Ayat Ismail
Journal of Building Construction and Planning Research (JBCPR) , 2018, DOI: 10.4236/jbcpr.2018.63010
Abstract: With the drastic rise in divorce rates in Egypt in the last few decades, targeting female-headed households as new housing segment is becoming increasingly crucial. Female-headed households are categorized as part of the housing vulnerable groups supported by the government. The housing needs, preferences and the market navigation patterns of this group are the study matter of this paper. While this group shares similarities in the housing needs with the two-parent families there are defined differences in the housing presences and market navigation patterns of the two groups. The paper also sheds the light on how the social characteristics of the female-headed households determine the housing problems they face with the current market offerings. Then, it outlines a typology of the housing preferred by the female heads, with the aim of generating recommendations that would help create more inclusive and satisfactory housing market offerings tailored for them. The proximity of the workplace to the housing unit in addition to the presence of an active community center within the neighborhoods was on top of their housing demands.

Abstract: The quality requirements of drug donation are different from those of other donated items. Purpose: To describe and assess key aspects of pharmaceutical donations in Sudan, the kinds of benefits and drawbacks associated with drug donations, and the government controlling role in the donation process. Methods: Retrospective and prospective studies were conducted in the period from April 2007 to Mar 2008 in the Federal Ministry of Health (FMOH) and some working NGOs’ data bases. Some quality aspects of donated drugs were explored. Six randomly selected nongovernmental organizations (NGOs) were examined for the relevance and some aspects of quality of donated drugs such as whether the donated drugs were listed in the National Essential Drug List, or labeled in International Nonproprietary Names, their dosage forms, the language on the package and if the donated drugs were sampled or returned ones. Results: The study showed that most of the donated drugs were relevant to NEDL normative standards. The median times from the date of arrival to the date of expiration were more than 400 days. The time prior to expiration range between 44.8% and 47.5% were found less than one year in arrival. The top ten therapies were accounted for about 40 shipped items. The study was revealed that Sudan did not develop its own guidelines for drug donations and NGOs are making no effort to develop written donation policies. Conclusion: development of national guidelines for drug donations is essential to control the donated drugs in Sudan.
Particle Swarm Optimization for Nano-Particles Extraction from Supporting Materials
Mohamed abd-ElRahman Abdou
International Journal of Image Processing , 2011,
Abstract: Evolutionary computation for image processing is an encouraging research area. Transmission electronmicroscopy (TEM) images when used to characterize metallic and non-metallic nano-particles (size,morphology, structure, or composition), need such advanced image processing algorithms. This paperpresents an efficient evolutionary computational method, particle swarm optimization (PSO), for automaticsegmentation of nano-particles. A threshold-based segmentation technique is applied, where imageentropy is attacked as a minimization problem to specify local and global thresholds. We are concernedwith reducing wrong characterization of nano-particles due to concentration of liquid solutions orsupporting material within the acquired image. The obtained results are compared with manualtechniques and with previous researches in this area.

Abstract: Using the equation of motion expression in a curved space proper time is a useful method to explain the relation between the curvature of space-time and the potential of any field obtained. Taking into account the expression for the Hamiltonian density, the effect of fields, as well as the effect motion, on the mass, and, their effect on energy is found. The new expression of energy reduced to the ordinary Newton’s energy expression. It also explains the gravitational red shift.

Journal of Information Security (JIS) , 2015, DOI: 10.4236/jis.2015.63022
Abstract: The trade off between the energy consumption and the quality of the received image should be considered as a main point in the techniques design in Wireless Sensor Network (WSN). This paper analyzes the performance of multiple image encryption algorithms with different approaches. And also, it introduces two proposed modulation techniques to enhance the performance of WSN. These two techniques merge both the image and the audio in one signal. The merging process enhances the energy consumption data rate. In addition, it removes the effectiveness of the jamming completely from both the reconstructed image and reconstructed audio signal at the receiver. So, the receiver will reconstruct the image without jamming effectiveness. The paper introduces a proposed audio encryption algorithm. The use of encryption algorithms for both image and audio signals with the merging process enhances the security level. Popular metrics are used to compare between these image encryption algorithms and also to show the benefits from these enhancements. The results show the preference of one of these image encryption algorithms to others. And also, the merging process enhances the bit rate to high level.

Abstract: Cardiovascular disease remains the leading cause of mortality and morbidity despite the identification of major risk factors and risk reduction strategies. Myocardial infarction (MI) is a relevant cardiovascular worldwide event for morbidity and mortality. In most cases, sudden cardiac death is triggered by ischemia-related ventricular tachyarrhythmia and accounts for 50% of deaths from cardiovascular disease in developed countries. This is a descriptive analytical case control study aimed to determine D-dimer, PT and PTT level and among patients with acute myocardial infarction conducted in Sudan cardiac center hospital. Thirty patients after MI and twenty normal controls have been studied. The MI patients also include co-exist disease diabetes and hypertension, they receive different anticoagulants therapy. The result demonstrates a significant increase post MI in the mean level of D-dimer (p = 0.00) whereas none significantly compares to control group. There are no differences between INR (0.393), PTT (0.648) and PT (0.393), parameters between cases and controls. In conclusion, our study reveals higher D-dimer level among patients than the control. In conclusion, serum D-dimer levels appear to be useful for diagnosing MI and may assist in the prediction of mortality among those patients which are presented with acute chest pain or known diagnosed with MI and should be done as indicator for thrombosis risk during therapy in post MI.

Remote Sensing , 2011, DOI: 10.3390/rs3030570
Abstract: Hyperspectral image analysis is gaining momentum in a wealth of natural resources and agricultural applications facilitated by the increased availability of low-cost imaging systems. In this study, we demonstrate the development of the Vegetation Mobile Mapping System (VMMS), a low-cost hyperspectral sensing system that is supported by consumer-grade digital camera(s). The system was developed using off-the-shelf imaging and navigation components mainly for ground-based applications. The system integrates a variety of components including timing and positioning GPS receivers and an Inertial Measurement Unit (IMU). The system was designed to be modular and interoperable allowing the imaging components to be used with different navigation systems. The technique used for synchronizing captured images with GPS time was presented. A relative radiometric calibration technique utilizing images of homogeneous targets to normalize pixel gain and offset parameters was used. An empirical spectral calibration method was used to assign wavelengths to image bands. Data acquisition parameters to achieve appropriate spatial coverage were presented. The system was tested in ground-based data collection and analysis experiments that included water quality and vegetation studies.
