Development, Validity, and Reliability of the Perceived Telemedicine Importance, Disadvantages, and Barriers (PTIDB) Questionnaire for Egyptian Healthcare Professionals.

BackgroundThis study aimed to develop and investigate the psychometric properties of the Perceived Telemedicine Importance, Disadvantages, and Barriers (PTIDB) questionnaire for healthcare professionals (HCPs) in Egypt. This study was conducted in three phases: (1) development of the questionnaire, (2) preliminary testing of the questionnaire, and (3) investigation of its validity and reliability using a large survey.MethodsA cross-sectional survey was conducted over two months. A convenience sample of 691 HCPs and clerks from 22 governorates accessed the online survey. The construct validity was assessed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and internal reliability.ResultsThe initial Eigenvalues showed that all 19 items of the questionnaire explained 56.0% of the variance in three factors. For Factor 1 (importance), eight items were loaded on one factor, with factor loading ranging from 0.61 to 0.78. For Factor 2 (disadvantages), seven items were loaded on one factor with factor loading ranging from 0.60 to 0.79. For Factor 3 (barriers), four items were loaded on one factor, with factor loading ranging from 0.60 to 0.86. The CFA showed that All loadings ranged from 0.4 to 1.0, with CFI = 0.93 and RMSEA = 0.061. All the factors had satisfactory reliability; 0.87 for ''Importance'', 0.82 for ''Disadvantages'', and 0.79 for ''Barriers''.ConclusionThe PTIDB questionnaire has an acceptable level of validity and internal consistency, at a readability level of 12th grade. The retest reliability, however, still needs to be tested

Comparison of Desired-Genetic-Gain Selection Indices in Late Generations as an Insight on Superior-Family Formation in Bread Wheat (Triticum aestivum L.)

Wheat is one of the most important sources of food worldwide. A selection index helps in making selection decisions and permits the exploitation of information on correlated traits to improve yields. Two cycles of pedigree selection based on the desired-genetic-gain selection index were imposed to identify the best index to isolate promising lines. The base population was composed of 120 families of bread wheat in the F6 generation. Eight combinations were constructed from six traits, i.e., days to heading (DH), number of spikes/plant (NS/P), grain yield/plant (GY/P), number of grains/spike (NG/S), mean spike weight (MSW) and mean grain weight (GW). The narrow-sense heritability of NS/P, NG/S, MSW and GW increased from cycle 1 to cycle 2, revealing an increase in the observed gain and homogeneity of the selected families for these traits from cycle to cycle. After the second cycle, the observed gain in GY/P ranged from 9.5 to 23.75% of the mid-parent. The best index for improving GY/P was index 2 (composed of GY/P, NS/P, NG/S, MSW and GW). The indices involving DH were inferior for improving GY/P. The desired-genetic-gain index was efficient in simultaneously improving several involved traits and was a good method to preserve genetic variability. Furthermore, six superior promising families were identified

Cholecalciferol for prophylaxis against antituberculosis therapy-induced liver disorders among naïve patients with pulmonary tuberculosis: A randomized, comparative study

Background: Patients in countries endemic for chronic viral hepatitis are more vulnerable to antituberculosis therapy-induced liver disorders (ATT-LDs). The aim of this study was to explore the role of cholecalciferol in prophylaxis against ATT-LD among patients with pulmonary tuberculosis (TB) receiving ATT. Material and Methods: We conducted a hospital-based, prospective, randomized, comparative study which included 300 consecutive, naïve patients with pulmonary TB eligible for ATT. The patients were randomly allocated to Group A (150 patients who received ATT) and Group B (150 patients who received ATT with cholecalciferol) who had clinical evaluation, laboratory investigations, and imaging studies. Statistical analysis used student's t-test and Chi-square test were used as appropriate to compare the variables between the study groups. Results: The study population mean age was 35.6 ± 15.3 years. The overall incidence rate of ATT-LD among the study population was 9.3%; the incidence rate was significantly higher among Group A patients compared to those of Group B (13.3 vs. 5.3%;P = 0.001). The onset of ATT-LD was significantly earlier among patients of Group A compared to those of Group B (31.4 vs. 58.7 days,P = 0.027), while the duration of ATT-LD was significantly longer among patients of Group A compared to those of Group B (34.8 vs. 16.9 days,P = 0.009). No adverse effects related to cholecalciferol use were observed. Conclusions: Adjuvant cholecalciferol supplementation may be protective against ATT-LD without extra adverse effects. Before recommending the routine use of cholecalciferol supplementation for prevention of ATT-LD, larger scale studies are recommended

Hookworm infection among patients with pulmonary tuberculosis: Impact of co-infection on the therapeutic failure of pulmonary tuberculosis

Objective/background: The aim of this study is to determine the rate of hookworm infection among patients with pulmonary tuberculosis (TB) and to find out if there is a relation between hookworm infection and the therapeutic failure of pulmonary TB. Methods: We carried out a prospective, hospital-based study. The study included 231 naıve patients with pulmonary TB, consecutively. Patients were evaluated at the 4th month of therapy for persistence of Mycobacterium tuberculosis infection. All patients had clinical evaluation, laboratory investigations (including sputum culture and stool microscopic examination), and imaging studies (abdominal ultrasonography and chest radiography). Results: The study population mean age was 42.7±13.9 years old with 26.8% of them 40 years old or more. Out of 231 patients, 133 (57.6%) were men. Therapeutic failure rate of pulmonary TB was 29.4%. Hookworm infection was diagnosed among 16.5% of patients and 27.7% had diabetes mellitus (DM). Using multivariate analysis, it was found that age of 40 years or more (odds ratio [OR] 8.4; 95% confidence interval [CI] 1.7–41.3; p = .009), hookworm infection (OR 7.6; 95% CI 1.2–49.9; p = .034), and DM (OR 5.9; 1.2–28; p = .027) were independently associated with therapeutic failure of pulmonary TB among the study population with pulmonary TB. Conclusion: In conclusion, the rate of therapeutic failure of pulmonary TB is high. Besides older age and DM, hookworm infection can reduce the therapeutic response of pulmonary TB. Screening for and control of DM and hookworm infection among patients with pulmonary TB may improve their therapeutic response

Knowledge, Applicability, and Barriers of Telemedicine in Egypt: A National Survey

Objectives. The study is aimed at evaluating knowledge, attitude, and barriers to telemedicine among the general population in Egypt. Methods. A questionnaire-based cross-sectional design was carried out among the general Egyptian population. A convenience sampling method was used to approach the eligible participants from University Teaching Hospitals of eight governorates from May to July 2020. Results. A total of 686 participants filled the questionnaire (49.4% were males, mean age 36.7±11.2 years old). Half of the participants stated that they previously used a telemedicine tool, mainly to follow up laboratory results (67.3%). Video or phone calls (39.3%) and mobile applications (23.7%) were the most commonly recognized telemedicine tools by the participants. The included participants exhibited a high level of knowledge and attitude towards telemedicine. On the other hand, 21.9% stated that telemedicine services could jeopardize patient privacy. 32.8% reported that telemedicine service could lead to disclosing medical information to people who are not authorized to do so. Almost half of the participants agreed to strongly agreed that telemedicine service could increase medical errors. 60.80% of the participants said that they are more likely to prefer telemedicine than traditional ways. However, 13.70% stated that telemedicine is more likely to be challenging to use. Conclusion. The Egyptian population has high knowledge about the applications of telemedicine. In addition, the vast majority of Egyptians appear to perceive the benefits of telemedicine positively and are willing to use it. However, some barriers that have been found must be taken into consideration to adopt telemedicine successfully, especially for people who are old, are low educated, and live in remote areas. Future studies should address the utility of telemedicine in improving the quality of healthcare and patient’s health outcome and quality of life
