Suleiman I. Sharif, Aseel H. Nassar, Fatima K. Al-Hamami, Maha M. Hassanein, Ashkur H. Elmi, Rubian S. Sharif
Pharmacology & Pharmacy (PP) , 2015, DOI: 10.4236/pp.2015.61002
Abstract: Background: Data with regard to local drug prescribing in pediatric population is scarce. This study was carried out to investigate the patterns of drug prescribing for pediatric outpatient in a general hospital in the United Arab Emirates. Methods: A total of 707 prescriptions were collected from a governmental hospital in Umm Al Quwain, United Arab Emirates covering the months of June and July, 2014. Encounters issued for patients older than 12 years were rejected. A total of 520 prescriptions for age groups ranging from 1 week to 12 years were studied. Prescriptions were analyzed using WHO drug use indicators. Results: All prescriptions were electronic and head lettered by the name of the hospital. Average number of drugs per prescriptions was 2.6 and all drugs were generics. Name of patient, age and gender and prescriber’s name and E-signature were present in 100%. Patient’s address, allergy and diagnosis were present in 21.15%, 83.26% and 64.42% of prescriptions respectively. Complete dosage regimen was present in all encounters. Patients were prescribed one, two, three, four or more than four drugs per prescription in 23.84%, 27.88%, 26.53%, 12.69%, and 8.65% respectively. The most commonly prescribed therapeutic classes of drugs were antibiotics (44.60%), antihistamines (43.65%), and analgesics/antipyretics (32.30%). The most commonly prescribed drugs among each class were amoxicillin (40%), xylometazoline (61.23%), and paracetamol (87.5%). Conclusion: Present results indicate that prescribing trends for pediatric population seems to be rational. However, there is over use of antibiotics and there are some areas that warrant further attention by the prescribers for a more significantly rational prescribing.

Aseel S. Mahmood, Abdul-Kareem A. Al-Kazaz, Ali H. Ad’hiah, Khadier K. Mayouf
Journal of Biosciences and Medicines (JBM) , 2017, DOI: 10.4236/jbm.2017.59001
Abstract: Fifty-one rheumatoid arthritis (RA) patients were enrolled to assess the gene expression of tumor necrosis factor-alpha (TNF-α) by reverse transcription quantitative polymerase chain reaction (qRT-PCR) in etanercept-treated RA patients, with some emphasis on clinical and biological markers of disease. The results revealed that the ΔCt mean range in total, male and female RA patients and controls was 1.286 ± 1.226 - 4.023 ± 0.856 and the differences were not. Laboratory and clinical findings in subgroups of patients also showed no significant variations in the distribution of 2-ΔΔCt means, with the exception of anti-cyclic citrullinated peptide (ACCP) antibodies. The lowest expression was observed in moderate positive patients (1.566 ± 1.104) compared to low and high positive patients (4.061 ± 1.366 and 9.668 ± 3.518, respectively) for ACCP antibodies, and the difference was significant (p = 0.043). Inspecting the 2-ΔΔCt means in duration of disease and gender revealed that male patients recorded a lower mean than female patients (0.827 ± 0.550 vs. 4.143 ± 1.317) at <5 years disease duration, while at >10 years duration of disease, female patients showed a lower mean than male patients (1.242 ± 0.372 vs. 5.607 ± 3.334). However, both differences were not significant. It is concluded that etanercept was effective in normalizing the TNF gene expression, but variations that were related to gender, duration of disease and some biological markers of disease, were observed.
Venn Diagram Approach to Heisenberg Inequalities
Nassar H. S. Haidar
Applied Physics Research , 2012, DOI: 10.5539/apr.v4n2p253
Abstract: We report on a proof to the Heisenberg inequalities, for both vector-like and scalar-like variables, that is based on statistical dependence of quantum events on appropriate Venn diagrams. A similar proof is provided for the “energy-velocity” uncertainty principle of Haidar (2010).
Inversion of Fourier Transforms by Means of Scale-Frequency Series
Nassar H. S. Haidar
International Journal of Engineering Mathematics , 2014, DOI: 10.1155/2014/686785
Abstract: We report on inversion of the Fourier transform when the frequency variable can be scaled in a variety of different ways that improve the resolution of certain parts of the frequency domain. The corresponding inverse Fourier transform is shown to exist in the form of two dual scale-frequency series. Upon discretization of the continuous scale factor, this Fourier transform series inverse becomes a certain nonharmonic double series, a discretized scale-frequency (DSF) series. The DSF series is also demonstrated, theoretically and practically, to be rate-optimizable with respect to its two free parameters, when it satisfies, as an entropy maximizer, a pertaining recursive nonlinear programming problem incorporating the entropy-based uncertainty principle. 1. Introduction We revisit the classical problem of recovering a Fourier transformable signal in , , from its Fourier transform; see, for example, [1, 2], image . The space is the set of all real functions for which the integral exists. Obviously, the function to be integrated in (1) is the product and when the variable , the function will oscillate extremely rapidly. Then in order to follow the variations of the product meaningfully in a -quadrature formula, see, for example, [3], for (1), there is a need for a large number of -points, even for slowly varying . Consequently, the faster the decreases as , the more the tractable computationally the integral (1) will be, and the more accurate are its numerical evaluations. Bandlimiting of signals has been a practical way for easing the previous problem. A fact that has so far been motivating the wide engineering interest in bandlimited signals, for which where is the band width of with an image having the compact support of . Inversion of bandlimited signals is currently performed by projections onto convex sets (POCS) algorithms [4], which encompass the Gerchberg-Papoulis algorithm [5]. In this work we report on a novel robust semianalytical method for integration of (1) to recover a signal that is not necessarily bandlimited. In this method, the frequency variable can be scaled in a variety of different ways that improve the resolution of certain parts of the frequency domain. The corresponding inverse Fourier transform is shown to exist in the form of two dual scale-frequency series. Upon discretization of the continuous scale factor, this Fourier transform series inverse becomes a certain nonharmonic [6] double series, a discretized scale-frequency (DSF) series. This DSF series is demonstrated, for the first time in this work, to be the proper

Z. Gad, O. Nassar, H. Soliman, S. Mohamed, M. Mohamed
Journal of Cancer Therapy (JCT) , 2018, DOI: 10.4236/jct.2018.94030
Abstract: Background: The current treatment for pseudomyxoma peritonei (PMP) consists of radical cytoreductive surgery (CRS) followed by hyperthermic intra-peritoneal chemotherapy (HIPEC). Aim: To assess PMP patients regarding the clinical and pathological characteristics, the treatment including surgery (CRS) and chemotherapy either HIPEC type or post-operative systemic chemotherapy aiming to evaluate end results regarding recurrence and survival. Patients and Methods: This retrospective study included 39 patients with PMP who were diagnosed, treated and followed-up from 2009-2014 at National Cancer Institute, Cairo, Egypt. Results: High grade mucinous adenocarcinoma was found in 23.1% of patients. Patients with low grade tumor showed higher survival rate compared with patients with high grade disease. The mean operative PCI score (peritoneal cancer index) that was done to all patients who were explored was 15.81. Our study reported success to achieve complete cytoreduction that was combined with HIPEC in 44% of patients who were planned for this modality. Treatment related postoperative grade (3 - 5) complications mainly surgery related developed in 17.3 of patients. Operative mortality was 22.2%. The follow up period in our study was quite short (mean 22.9). However the overall survival at the end of the follow up in our study was 48.7%, 1 year survival was 82%, and 2 year survival was 41%. The overall survival in patients treated with CRS and HIPEC was 66.6%, with 1 year and 2 year survival of 91% and 66.6% respectively. Only 2 patients developed recurrent disease during the follow up period. Conclusions: The outcome of PMP treatment process is extremely variable. Combined CRS and HIPEC is considered the best therapeutic approach for patients with PMP. Surgical experience combined with proper patient selection have to be built up together to improve the outcome. That could only be achieved through more centralization of patients’ treatment in specialized units or center.

Heba Nasrate, Aseel Shamlawi, Muhammad W. Darawad
Health (Health) , 2017, DOI: 10.4236/health.2017.912120
Abstract: Background: Physical Restraint (PR) has been widely used in the intensive care units, which aims to protect patients and maintain their safety. With all benefits of PR, there are many complications and risks from improper utilization. Further, no Jordanian studies have found to educate nurses regarding the proper PR utilization. Purpose: To evaluate the impact of an educational program on nurses’ knowledge, attitude and practice regarding PR use in ICUs. Methods: A pre-experiment with one-group pretest-posttest design was used among 40 ICU nurses. A self-administered questionnaire was used to evaluate nurses before the education program and two weeks after its completion. Results: After implementation of the program, nurses demonstrated a significant difference in knowledge scores between pretest (M = 10.35 ± 1.73) and posttest (M = 13.30 ± 1.47) (t = 9.92; df = 39; P = 0.000), attitudes scores (M = 27.90 ± 2.79 vs. M = 30.40 ± 2.32) (t = 4.61; df = 39; P = 0.000), and practice scores (M = 36.85 ± 1.98 vs. M = 40.52 ± 1.60) (t = 11.59; df = 39; P = 0.000). Conclusion: Service-education program can improve ICU nurses’ knowledge, and enhance their attitudes and practices towards physical restraint. Such improvement is expected to be reflected in improving the quality of care delivered to the patients, and decreasing complications of malpractice regarding physical restraint.
