Comparison of Preventive Care Provided to Dialysis Patients by Nephrologists and to Patients Followed in General Medical Clinics: Compliance with American College of Physicians Guidelines

Hemodialysis International (2002)

Abdullah Hamad Kameswari Lakshmi Mohammad Khedr Hisham Ibrahim Laurette Cantelmo

Most end‐stage renal disease (ESRD) patients do not have primary‐care providers, and preventive medicine often is provided by their nephrologists. Little has been written about their success in providing this care. We studied all patients on dialysis at our hospital and compared their preventive care to a control group followed in the general medical clinic. The general medical group showed higher compliance with Pap smears (89% vs 48%), mammography (87% vs 62%), fecal occult blood testing (75% vs 50%), and pneumococcal vaccination (55% vs 28%). The ESRD group had better compliance with influenza vaccination (70% vs 55%) and lipid profile (100% vs 75%). When the subgroup of patients on hemodialysis (HD) was compared with patients on peritoneal dialysis (PD), it was shown that HD patients were more likely than PD patients to receive preventive care. We also compared diabetes‐specific care. The ESRD group had a higher rate of HbA 1C (100% vs 78%) and lipid monitoring (100% vs 76%), diabetes education (100% vs 84%), and podiatry visits (70% vs 38%). There was no difference in ophthalmologic examination or influenza vaccination. We found that nephrologists provide preventive care to ESRD patients with success approximately equal to primary‐care physicians in our institution, although in different parameters. Ready access to dialysis patients and their blood and unit‐specific policies contribute to compliance that is above national averages. Further improvements can be made by additional preventative measures policies, by physician and patient education, and by monitoring primary‐care compliance in the chart.

Impact of Price Changes on the Exported Quantities of Some Egyptian Agricultural Crops in its Most Important Foreign Markets

Deleted Journal (2024)

M. G. Mahdy Hanan Al-Ameer Mohammad Khedr

This research aimed to study the impact of changing prices of some Egyptian export agricultural crops on the volume of exported quantities of those crops (potatoes, onions, oranges, grapes), using some economic models such as the Direct Model and the Substitution Elasticity Model in its most important foreign markets, where the specified prices are The main factor in determining the volume of demand for exported crops and determining the degree of flexibility of foreign markets for the study crops. The results showed that the elasticity of the Saudi, Emirati, Kuwaiti, Russian, and English markets for potatoes amounted to about -0.370, -0.508, -0.892, -0.417, -0.512, respectively. This explains that by increasing the export price of potatoes by 1%, there is a decrease in the quantity of exports. Potatoes for these markets amounted to about 0.37%, 0.50%, 0.89%, 0.41%, 0.51%, and their significance was proven statistically at a level of significance between 1% and 5%. The results also showed that the elasticity of the Saudi, Emirati, Kuwaiti, Russian, and English markets for onion crops amounted to about -0.503, -0.723, -0.344, -0.627, -0.576, respectively. This explains that by increasing the export price of onions by 1%, there is a decrease in the quantity Onion exports to these markets amounted to about 0.50%, 0.72%, 0.34%, 0.62%, 0.57%, and their significance was proven statistically at a level of significance between 1% and 5%.

The association between statin therapy during intensive care unit stay and the incidence of venous thromboembolism: a propensity score-adjusted analysis

BMC Pharmacology and Toxicology (2013)

Shmeylan Al Harbi Mohammad Khedr Hasan M. Al‐Dorzi Haytham Tlayjeh Asgar Rishu

Abstract Background Studies have shown that statins have pleiotropic effects on inflammation and coagulation; which may affect the risk of developing venous thromboembolism (VTE). The objective of this study was to evaluate the association between statin therapy during intensive care unit (ICU) stay and the incidence of VTE in critically ill patients. Methods This was a post-hoc analysis of a prospective observational cohort study of patients admitted to the intensive care unit between July 2006 and January 2008 at a tertiary care medical center. The primary endpoint was the incidence of VTE during ICU stay up to 30 days. Secondary endpoint was overall 30-day hospital mortality. Propensity score was used to adjust for clinically and statistically relevant variables. Results Of the 798 patients included in the original study, 123 patients (15.4%) received statins during their ICU stay. Survival analysis for VTE risk showed that statin therapy was not associated with a reduction of VTE incidence (crude hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.28-1.54, P = 0.33 and adjusted HR 0.63, 95% CI 0.25-1.57, P = 0.33). Furthermore, survival analysis for hospital mortality showed that statin therapy was not associated with a reduction in hospital mortality (crude HR 1.26, 95% CI 0.95-1.68, P = 0.10 and adjusted HR 0.98, 95% CI 0.72-1.36, P = 0.94). Conclusion Our study showed no statistically significant association between statin therapy and VTE risk in critically ill patients. This question needs to be further studied in randomized control trials.

Implications of Serum Anti-Ceramide Antibodies and Interleukin 4 on Nerve Damage and Physical Impairments Among Leprotic Patients: A Case-Controlled Study.

PubMed (2022)

Mohamed Zaky Zakaria Mahran Obaid Mohammad Khedr Hala El-Sokkary Mohamed L. Elsaie

Leprosy is a chronic granulomatous disease affecting skin and nerves with a range of clinical and immunological responses.The study aimed to identify levels of IL-4 and antibodies to ceramide in the sera of leprosy patients and healthy subjects using enzyme linked immunosorbent assay (ELISA) to evaluate their possible role in disease severity and their correlation to nerve involvement and physical impairments.This study included 25 patients with multibacillary leprosy, 25 with paucibacillary, and 25 healthy controls who were subjected to history taking, clinical examination, and identification of sites and morphology of skin lesions, nerve examination, eye examination, as well as sensory examination. Slit skin smear examination was used for diagnosing paucibacillary (PB) and multibacillary (MB) leprosy cases. Anti-ceramide antibody (ACA) and IL-4 titers were estimated and correlated with the type of leprosy, disease duration, nerve damage, and disabilities.Serum ACA and IL-4 levels were significantly higher in MB than its level in PB leprotic patients and controls. A significant positive correlation was established between nerve affection; physical impairments and serum levels of ACA and IL-4.Levels of ACA and IL-4 can impact nerve affection in leprotic patients and can serve as potential biomarkers of disease progression J Drugs Dermatol. 2022;21(3):284-291. doi:10.36849/JDD.5543.

Improving the predictability of ICU illness severity scales

Federated Conference on Computer Science and Information Systems (2011)

Mohammed Alqarni Yaseen M. Arabi T. Kakiashvili Mohammad Khedr Waldemar W. Koczkodaj

This study demonstrates how to improve the predictability of one of the commonly used ICUs severity of illness scales, namely APACHE II, by using the consistency-driven pairwise comparisons (CDPC) method. From a conceptual view, there is little doubt that all items have exactly equal importance or contribution to predicting mortality risk of patients admitted to ICUs. Computing new weights for all individual items is a considerable step forward since it is based on reasonable to assume that not all individual items have equal contribution in predicting mortality risk. The received predictability improvement is 1.6% (from 70.9% to 72.5%) and the standard error decreased from 0.046 to 0.045. This must be taken as an indication of the right way to go.

Estimation of Water Footprint and Its Most Important Indicators for Some Egyptian Export Crops

Deleted Journal (2024)

M. G. Mahdy Hanan Al-Ameer Mohammad Khedr

This research aimed to estimate the total water footprint of the most important Egyptian export crops, as well as the internal and external water footprints of the study crops. It was shown through the results of the research regarding the potato crop that the percentage of dependence on external water imports reached its lowest level in 2012 at about 2.6%, and it also reached its maximum level. In 2015 year, it was about 11.4% the average percentage of dependence on external water imports for potatoes was about 7.6% as an average for the study period. The standard deviation was about 1.41 and the coefficient of variation was about 18.6%. The percentage of dependence on local water resources was also about 11.4%. Its lowest limit was about 88.4% in 2005, and its maximum in 2009 was about 98.1%. The average dependence on water resources was about 92.4% as an average for the study period. As for the grape crop, it was found that the percentage of dependence on external water imports for grapes reached its lowest limit in 2018 was about 0.25%, and its maximum in 2004 was about 7%. The average percentage of dependence on external water imports for grapes was about 2.4%, while the percentage of dependence on local water resources reached its lowest limit in 2004 at about 93%, and reached its maximum in 2018 at about 99.75%, and the average dependence on water resources reached about 97.6% as an average for the period of the study.
