This research aimed to 1) describe some indicators related to distance education among university rural youth, 2) measure the academic motivation of respondents, 3) identify factors related to the academic motivation of respondents, and 4) identify the impact of distance education on the academic motivation of young rural university. Data were collected via an electronic questionnaire form distributed to the students of the Faculty of Agriculture, Ain Shams University via WhatsApp groups; the rural students were urged to complete it. The number of completed forms was 416 during the period from June and July 2021. Frequencies, percentages and average, range, standard deviation, as well as correlation coefficient were used for data analysis and presentation. The results showed that the majority of respondents use the WhatsApp application (80%), the mobile internet package (54.6%), and the majority (51.9%) use online education for 2-3 hours per day. The results also showed that the average overall academic motivation of respondents was 109.76 ((which is approximately 78.4% of the overall scale). The results showed that there are significant correlations between the overall level of the students’ academic motivation with the variables of the overall level of electronic applications and smart devices used by respondents to access online learning and the total number of hours spent in online learning.  The results also showed the positive effect of online learning on academic motivation, according to 72.8% of respondents, where the motivation of internal organization had the greatest impact on online education according to 80.3% of respondents

Evaluation of community pharmacists' awareness towards Middle East respiratory syndrome: a simulated client method.

Middle East Respiratory Syndrome (MERS) is a viral respiratory disease caused by a coronavirus variant in the Arabian Peninsula. There is a lack of information regarding awareness and practices of community pharmacists in Qatar for this contagious disease. To determine the quality of the MERS-related information, recommendations, and counselling practices provided by Qatar's community pharmacists by using Simulated Client Method (SCM). An observational cross-sectional study using a non traditional SCM was conducted in community pharmacies of Qatar from February 2017 to April 2017. A total of 30 community pharmacies were visited twice by two independent simulated clients and data regarding, provision of evidence -based information, recommendations and counselling practices were collected to assess the competency of pharmacists in managing MERS as a primary care problem. Both descriptive and inferential statistical methods were used for data analysis. In present study, majority of pharmacists encountered were male and younger than 45 -year -old with 44 (73.3%) each. The average number of pharmacists who did not ask about the patient's current medical conditions 56 (93.3), medications 58 (97.5%), allergies, and smoking status in both scenarios were not asked by any of the pharmacist. Most of the pharmacists gave an incorrect explanation of MERS 43 (71.7%). The overall quality counselling score for the pharmacists (mean +/- SD; median (IQR)) was {27.5 +/- 4.5; 28.5 (25.3-30.0)}. Quality counselling was significantly related to the type of pharmacy (p=0.0478). Qatar community pharmacist's MERS related information, recommendations, and counselling practices were below expectations and inconsistent, thus urging the need for continuous professional development

Application of the Health Belief Model -Based Educational Intervention on Hand Hygiene Performance of Intensive Care Units' Nurses

Background: Practicing hand hygiene is a simple yet effective way to prevent infections. Cleaning hands can prevent the spread of germs, including those resistant to antibiotics and are becoming difficult, if not impossible, to treat. On average, healthcare providers clean their hands less than half of the times they should.Aim of the study: This study aimed to apply the health belief model based educational intervention on hand hygiene performance among nurses working in adults and pediatric intensive care units.Materials and methods: A quasi experimental research design was used in this study. The study was conducted at pediatric and adult intensive care unit; at Tanta University Hospital. All available nurses 262who are working in the previously mentioned settings as the following: 118 nurses working in pediatric intensive care unit nurse and 144nurse working in adult intensive care unit. Tools of the study: Four tools were used to collect the data Tool I: Nurses' knowledge regarding Hand Hygiene Structured Questionnaire: it consisted of two parts: Part1: Socio demographic data of the nurses Part II: Nurses' Knowledge Regarding Hand Hygiene Performance. Tool II: Assessment of Nurses Barriers of Hand Hygiene Performance Questionnaire, Tool III: Hand Hygiene Perception Survey and Tool IV: Hand Hygiene Performance Observational Checklist. Result; the mean score of total hand hygiene performance using soap and water of nurses working in pediatric ICUs were 8. 85±1.02 and 10.10±1.84, while among adult ICUs nurses were 8.37±1.75and10.20±0.80 pre and post the educational intervention respectively. There was a significant difference of both groups in the; five Health Belief Model Construct in addition to nurses’ identified barriers of hand hygiene pre and post the intervention.Conclusion and recommendations: Total hand hygiene performance level and HBM construct regarding hand hygiene performance were higher among nurses working in pediatric and adult ICUs nurses post than pre application of the HBM educational intervention. Also, higher mean scores of the barriers of hand hygiene performance among all nurses in both ICUs pre compared to post intervention. Periodic and refreshment educational intervention related to hand hygiene is recommended for adult and pediatric ICUs nurses to improve their hand hygiene performance and further study for barriers in other ICUs is recommended. Keywords: Health Belief Model -Based Educational intervention, Hand Hygiene Performanc

Three regimens for re-treatment failure of Sofosbuvir-based therapy for chronic hepatitis-C genotype-4: a cohort study

Despite the high sustained virologic response (SVR) rates of direct-acting antiviral (DAAs) therapy, a small number of patients does not eradicate the virus, and these patients represent a challenge. This study aims to compare the outcomes of three second-line regimens for DAAs-experienced patients with chronic hepatitis C (CHC). This prospective observational study was conducted at the Damanhur Viral Hepatitis Center from January 2017 to February 2020. We included patients with CHC who did not achieve SVR after the complete course of Sofosbuvir/Daclatasvir±Ribavirin (SOF/DAC±RBV). The primary endpoint was SVR-12 after re-treatment. This study included 360 patients (with a mean age of 51.53±11.38 years). Approximately 51.1% of the patients were males, and 65.5% had liver cirrhosis. All patients of group 1 (45 patients) received SOF/VEL/VOX over 12-weeks; SVR-12 was achieved in 44 patients (97.8%). Group 2 (28 patients) received SOF/DAC/RBV over 24-weeks; (one patient was lost during follow-ups and one patient discontinued treatment due to hepatic decompensation). SVR-12 was achieved in 25 patients (96.2%). Group 3 (287 patients) received SOF/Ombitasvir/Paritaprevir/Ritonavir/RBV) over 12-weeks. Eight patients were lost during follow-ups, and one patient discontinued treatment due to grade 4 adverse events. SVR-12 was achieved in 276 patients (99.3%). There was no difference between the groups regarding their age, gender distribution, baseline viral load or comorbidities. Adverse events (thrombocytopenia, anemia, hyperbilirubinaemia and prolonged INR) were significantly higher in group 3, while group 1 did not experience any. The three studied retreatment regimens can be used for DAAs treatment-experienced patients considering availability. The SOF/VEL/VOX combination had the least adverse events

Validity of sphenoid ostium in relation to posterior wall of maxillary sinus by computed tomography

Background: Sphenoid sinus is the most inaccessible paranasal sinus, enclosed within the sphenoid bone and intimately related to numerous vital neural and vascular structures. Anatomic variation of the sphenoid sinus is well documented and may complicate surgery in such a place.Objective: To assess the reliability of preoperative computed tomography (CT) in determination of the distance between the posterior wall of maxillary sinus (PWMS) and the sphenoid sinus ostium (SSO) in the coronal plane.Patients and methods: This was a prospective study of the distance between the SSO and the PWMS in the coronal plane, which was measured both radiologically in preoperative CT and intraoperatively during endoscopic sinus surgery for patients in need for middle meatal antrostomy and sphenoid sinusotomy at the same side. Distances obtained by both techniques have been tested for the degree of correlation. Number of the included patients was 25.Results: Forty four nasal sides were included in the study. The mean distance between the sphenoid sinus ostium and posterior wall of maxillary sinus in the coronal plane was 6.6 ± 1.8 mm when measured by preoperative CT and 6.9 ± 1.9 mm when measured directly during surgery. No significant difference was found between the mean distances measured by both techniques (p = 0.246) with good agreement between them (r = 0.864).Conclusion: Preoperative CT may be a reliable tool to preoperatively determine the difference in depth between the PWMS and the SSO

Protective Role of Nanocurcumin in Cyclophosphamide-induced Cardiac Toxicity in Adult Male Albino Rat: A Histological, Immunohistochemical, Biochemical Study

Background: Cyclophosphamide (CYP) is a cardiotoxic agent with antineoplastic and immunosuppressive properties. Objectives: To detect the histological, immunohistochemical, biochemical cardiac toxicity of CYP and determine the protective effectiveness of nanocurcumin on the cardiac muscle of albino rats. Material and methods: The current work used forty Wistar rats allocated into four groups; normal control (I), sham control (II), CYP-treated (III) and concomitant protective CYP + nanocurcumin (IV). Results: CYP-treated group (III) showed fragmented, disrupted cardiac myocytes with cellular infiltrates and interstitial edema. Blood vessels were dilated congested. Cardiac myocytes showed pyknosis, vacuolations and some showed karyolysis. Much improvement was observed in group IV. The area percentage of fibrous tissue, TNF-α and iNOS immunoreactivity in CYP-treated group III showed statistically significant increase in contrast to that of the control group. Use of nanocurcumin in groups IV ameliorate these changes. Biochemically, there were significant increase in means of CK-MB, cTn-1, MDA, levels and decrease of GPx activity in group III (CYP -treated group) compared to the control group. Uses of nanocurcumin has been observed to improve these changes. Conclusion: Cyclophosphamide (CYP) had deleterious effects on the histological structure of the heart, cardiac enzymes, collagen fibers deposition and myofibroblast proliferation in albino rats. Administration of nanocurcumin with CYP injection could largely ameliorate these changes

Evaluating the Impact of a Collaborative Care Model in Diabetes Management in a Primary Healthcare Setting in Qatar Using Real-World Data

Objectives: To evaluate the impact of Collaborative Care Model (CCM) on diabetes-related outcomes among patients with diabetes attending a primary care setting. Methods: A multiple-time series, retrospective, observational study with a control group among patients with diabetes followed-up at Qatar Petroleum Diabetes Clinic. The impact of CCM on glycemic control, blood pressure, lipid profile, and anthropometrics was evaluated at baseline and up to 17 months of follow-up. Quantitative data were analyzed descriptively and inferentially using SPSS. Results: CCM significantly improved (p<0.05) the mean values (baseline vs. 17 months) of glycated hemoglobin A1c (6.9% vs. 6.5%), random blood glucose (194.38 mg/dL vs. 141.23 mg/dL), low-density lipoprotein cholesterol (3.7 mmol/L vs. 2.8 mmol/L), total cholesterol (5.43 mmol/L vs. 4.34 mmol/L), weight (78.52 Kg vs. 77.85 Kg), and body mass index (30.41 Kg/m2 vs. 30.17 Kg/m2) over 17-months within the intervention group; whereas, no significant changes occurred within the control group. Similarly, the between group comparisons demonstrated the superiority of CCM over usual care in improving several clinical outcomes. Conclusion: Inefficiencies in delivering diabetes care can be circumvented by the integration of CCM. The implementation of CCM in a primary healthcare setting improved several diabetes-related outcomes over 17-months

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
