Advances in Aging Research (AAR) , 2014, DOI: 10.4236/aar.2014.32022
Abstract:

Objective: This study aimed to assess the relationship of cognition, depression and anxiety to glycemic control in elders with diabetes. DM is a chronic medical condition. Its control depends on adherence to medical therapy and making decisions related to lifestyle changes. This decision making capacity is affected by many factors including cognition and psychological status. Design: It was a case control study. Setting: It was done in Ain Shams University Hospital inpatients and DM outpatient clinic, Cairo, Egypt. Participants: Of the one hundred diabetic patients aged ≥ 60 years, 50 had Hemoglobin A1c (HbA1c) ≥ 7.5 (cases) and 50 had Hb A1c < 7.5 (controls). Measurements: Cognition was assessed using minimental status examination (MMSE) test, Mattis Organic Mental Syndrome Screening Examination (MOMSSE) and Cambridge Cognitive Examination (CAMCOG) test. Geriatric depression scale-15 (GDS-15) was performed for depression assessment, while anxiety was assessed by DSM IV criteria. Laboratory investigations included: fasting blood sugar (FBS), post-prandial blood sugar (PPBS), glycated haemoglobin (Hb A1c)

Journal of Tuberculosis Research (JTR) , 2018, DOI: 10.4236/jtr.2018.64024
Abstract: Background: Distinguishing tuberculous pleural effusion (TPE) from other causes of exudative effusion is often challenging. Delay in treatment initiation can occur while awaiting histo-microbiologic confirmation owing to the paucibacillary nature of the disease. Sago-like nodules are the most common visual finding on gross thoracoscopic appearance. The primary objective was to determine the diagnostic utility of the presence of sago-like nodules on gross thoracoscopic appearance in TPE to help justify early initiation of tuberculosis (TB) treatment based on their finding while awaiting final histo-microbiologic confirmation. Secondary objective was to study the correlation between the presence of sago-like nodules and the final histo-microbiologic findings in pleural biopsy specimens. Methods: This was a retrospective-descriptive study of all patients with exudative pleural effusion who underwent diagnostic medical thoracoscopy (MT) at Hamad General Hospital during an eight-year period (from January, 2008 to December, 2015). Results: The presence of sago-like nodules on gross thoracoscopic appearance of the pleural surface had a sensitivity of 58%, a specificity of 89% and a positive predictive value of 97% for TPE with a diagnostic accuracy of 62%. There is significant association between the presence of sago-like nodules and demonstration of granulomatous inflammation in pleural biopsy specimens (P = 0.000). There is no association between sago-like nodules and positive TB smear and culture in biopsy specimens. Conclusion: The presence of sago-like nodules on gross thoracoscopic appearance has a high specificity and positive predictive value for TPE and significantly correlates with the presence of granulomatous inflammation. Patients from TB prevalent areas with exudative pleural effusion and sago-like nodules on gross thoracoscopic appearance may be commenced on TB chemotherapy while awaiting final histologic confirmation.

Haitham Taha
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.412148
Abstract:

The current study has examined by which cognitive factors at the field of phonological and visual processing, rapid automatized naming and morphological awareness, contribute to reading and decoding abilities among typical and poor native Arabic readers. In the current study, the performances of two groups of participants, typical and poor readers were compared through tasks that examined their performance with regard to the areas of functions mentioned above in addition to other tasks that examined their performance in reading meaningful and pseudo words. The study’s results have indicated that the visual and phonological processing skills play an important role in reading among typical and poor readers as well. Moreover, it was found that the visual and phonological processing skills of participants with poor reading skills were lower in comparison to participants with typical reading abilities.

Ischemic Monomelic Neuropathy after a Brachio-Cephalic AVF Creation: A Case Report and Review of Literature  [PDF]
Mohamad Taha
World Journal of Cardiovascular Surgery (WJCS) , 2017, DOI: 10.4236/wjcs.2017.73004
Abstract: Ischemic monomelic neuropathy (IMN) is an under-diagnosed and disabling complication of upper extremity hemodialysis access. The hemodynamic disturbance that occurs during the time of access creation can lead to both neurologic and ischemic complications. These complications are most commonly seen following proximal procedures involving the upper limbs. Diagnosis and treatment are often delayed, and even with early intervention, neurologic dysfunction may be irreversible. IMN can lead to significant long-term disability. Almost all cases of IMN occur with brachial artery-based access, procedures and the vast majority of patients are diabetic and females. I report a case of IMN after left BC AVF operation which was treated successfully by early access ligation, providing a review of the literature.

Salma M. S. El Said
Advances in Aging Research (AAR) , 2013, DOI: 10.4236/aar.2013.24024
Abstract:

OBJECTIVES: To evaluate outcome and risk factors, particularly the (APATCHE II) score in elderly patients after admission to a geriatrics intensive care unit (ICU). Methods: A cross sectional study of patients ≥ 60 years admitted to the intensive care unit (ICU) of the Geriatrics department at Ain Shams University Hospital over 2 years period. We recorded age, sex, previous medical history, primary diagnosis, date of admission and discharge or death and APACHE II score on admission. Results: 202 patients admitted to the ICU were studied. The mean ICU mortality rates for these patients were (32, 5%), the mean APATCHE II score was (19.07). 27.3% of patients who died had hypokalemia and 43.2% had hyponatremia. Conclusion: ICU mortality rate are higher in elderly patients particularly with long ICU stay and hyponatremia.

Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.26093
Abstract: In this research miswak leaves, agriculture wastes, available in large quantity in Saudi Arabia, was used as low-cost adsorbent for removing methylene blue (MB) dye. Equilibrium behavior of miswak leaves was investigated by performing batch adsorption experiments. The effects of [MB] 0, pH, contact time and adsorbent dose were evaluated. An alkaline pH (10.6) was favorable to the adsorption of MB dye. Adsorption isotherm models, Langmuir, Freundlich and Temkin were used to simulate the equilibrium data. Langmuir equation was found to have the highest value of R2 compared with other models. Furthermore, it was found that miswak leaves have a high adsorptive capacity towards MB dye (200 mg/g) and show favorable adsorption of MB dye with separation factor (RL < 1). In addition, pseudo-first- order, pseudo-second order and intra-particle diffusion were used to study the kinetics of MB adsorption onto miswak leaves. Adsorption process undergoes pseudo-second order kinetic as proved by the high value of R2 and the low value of sum of squared error (SSE percentage). Results indicated that intra-particle diffusion is not the limiting step, and the adsorption process is spontaneous as indicated by the negative value of the .

Taha A. Hanafy
Advances in Materials Physics and Chemistry (AMPC) , 2011, DOI: 10.4236/ampc.2011.13017
Abstract: Transient current (I-t), current-voltage (I-V) characteristics, and dc conductivity ln(σ) for bisphenol A corn-cobs (BPACC) sample were investigated. At higher temperatures, I-V characteristics reveal that the dc cur-rent for the sample undergoes two regions one due to ohmic conduction and the other has been attributed to Space charge limited current (SCLC). The activation energy (Ea), the electron mobility μo), effective electron mobility ?μe), the concentration of the charge’s concentrations in conduction band, trapping factor (θ) and the trap concentration (Nt) were calculated. At lower temperatures, the dc current exhibits a peculiar behavior for I-t regime and I-V characteristics. Transient current of BPACC sample exhibits approximately constant value at constant electric field and it has saturation value for I-V characteristics. The attained results suggest strongly the applicability of this material in the electrical applications.

Open Journal of Inorganic Chemistry (OJIC) , 2011, DOI: 10.4236/ojic.2011.13007
Abstract: Chemical preparation, X-ray single crystal, thermal analysis and IR spectroscopic investigation of (C7H10N)2 SO4 denoted NMAS are described. The NMAS crystallizes in the triclinic system with P-1 space group. Its unit cell dimensions are a = 9.6150(5) Å, b = 9.9744(3) Å, c = 10.2767(6) Å, α = 68.069(3)°, β = 62.929(2)°, γ = 67.285(3)° with V = 785.72(7) Å3 and Z = 2. The structure has been solved using direct method and refined to a reliability R factor of 3.62%. The NMAS structure is built up from chains containing all the components of the structure and parallel to the b axis, linked via N—H­­­­­···O hydrogen bonds. Stability between successive chains is performed by weak interactions originating from the organic cations.
Dielectric and Electric Modulus Behavior of Chlorinated Poly(Vinyl Chloride) Stabilized with Phenyl Maleimide  [PDF]
Taha A. Hanafy
Advances in Materials Physics and Chemistry (AMPC) , 2012, DOI: 10.4236/ampc.2012.24038
Abstract:

Dielectric constant, ε', dielectric loss factor, ε\", electric modulus, M, and ac conductivity, σac, of pure CPVC and that stabilized with 10 wt% of phenyl maleimide, PM, have been carried out. The dielectric properties have been studied in the temperature and frequency ranges; 310 K - 450 K and 1 kHz- 4 MHz, respectively. The incorporation of 10 wt% of PM as stabilizer for CPVC leads to reduce its Tg from 405K to 378K at 10 kHz. PM molecules within CPVC structure reduce the double bond, stabilizer effect, and cause the widely spacing between CPVC main chains, plasticizer effect.  Three dielectric relaxation processes namely ρ, α', and α were observed for pure CPVC. The first process was explained based on space charge formation or Maxwell-Wagner-Sillers, MWS, polarization. The second one is due to the segmental motion of the branching of CPVC. The third process occurs around the glass-rubber temperature, Tg, and is related to the micro-Brownian motion of the main polymer chain. Electric modulus and ac conductivity reveal that the conduction mechanism of CPVC is follow the correlated barrier hopping, CBH, while stabilized sample exhibits a quantum mechanical tunneling, QMT, type conduction.

The use of fiberoptic bronchoscope to remove aspirated tracheobronchial foreign bodies: Our experience  [PDF]
Abdulsalam Y. Taha
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.25077
Abstract: Background: Foreign body (FB) aspiration is a common emergency in our practice. The routine method of removal is via rigid bronchoscopy (RB) under general anesthesia. This is the preferred procedure particularly in children who form the major affected population. Fiberoptic bronchoscopy (FOB) has also been used for FB removal in many countries, though in Iraq, the standard mean remains rigid bronchoscopy. Objective: Herein, we present 5 cases of FB inhalation in adults in whom FOB was used for removal. The aim is to test its feasibility with literature review. Setting: the department of thoracic surgery/Sulaimania Teaching Hospital/Sulaimania/Iraq. Study Design: a prospective study of 5 patients. Patients and methods: 5 patients (3 females and 2 males) with different bronchial or laryngeal FBs in whom FOB was used as a method for removal are presented. The age ranged from 16 to 71 years. The clinical and radiographic features are recorded. In all these patients, initial FOB examination under local anesthesia transorally or via tracheotomy stoma was done. When removed by this method failed, RB under GA was used and when this failed, thoracotomy was the last resort. Results and Conclusions: FBs encountered in this paper consisted of pins (n = 2), sewing needle (n = 1), speech valve (n = 1) and a medical leach (n = 1). Three FBs (medical leach, speech valve and one pin) were successfully removed by FOB. A pin in RMB was visualized but failed to be removed by FOB and therefore, RB was required for its retrieval, while a needle in left lower lobe was invisible by both FOB and RB and thus surgery was necessary to remove it. We conclude that in adolescent or adult patients with bronchial FBs, FOB should be tried first for removal. If this fails then RB can be used. To increase its success, FOB should be combined with certain accessories like special FB forceps and fluoroscopy.
