The Future of TV and Online Video Platforms: A Study on Predictors of Use and Interaction with Content in the Egyptian Evolving Telecomm, Media & Entertainment Industries

This study examines the future of TV and online video platforms in the evolving Egyptian market through using the predictors of use and interaction. Built on the unified theory of acceptance and use of technology, and the theory of technology discontinuities and platforms development, this study extends its framework to explore the relationship between the intention of use and the interaction with content behavior. A sample size of 396 university students answered the survey questions. Unlike other studies, the study found that the perceived ease of use (PEU) is the only variable that is positively correlated to the intention to use online video platforms, yet it shows a significant positive relationship between consumer characteristics (including instrumental orientation [IO], perceived behavioral control [PBC], online flow experience [FLOW]) and intention to use online video platforms. Results show that people are watching less TV, yet the low disposable income might be a serious challenge toward the growth of video platforms. This study offers valuable indicators about changing consumer behavior in the research-weak transitional Egyptian media system

A hidden cause of infertility in hypothyroid patients

Methylene tetrahydrofolate reductase (MTHFR) gene mutations could be the cause of infertility in hypothyroid patients. Hence, it is worthy to screen for MTHFR gene mutations in infertile hypothyroid females and their partners if infertility persists after optimizing thyroid function

Protective Effect of Parsley Juice ( Petroselinum crispum

Parsley was used as a probe of the current experiment to prevent the behavioral, morphological and biochemical changes in the newborn brain following the administration of cadmium (Cd) to the pregnant mice. The nonanesthetized pregnant mice were given daily parsley juice (Petroselinum crispum) at doses of 20 mg/kg and 10 mg/kg. Pregnant mothers were given Cd at a dose of 30 mg/kg divided into 3 equal times. The newborns have been divided into 6 groups: Group A, mothers did not take treatment; Groups B and C, mothers were treated with low and high dose of parsley, respectively; Group D, mothers were treated only with Cd (perinatal intoxication); Groups E and F, mothers were treated with Cd doses and protected by low and high doses of parsley, respectively. Light microscopy showed that Cd-induced neuronal degeneration by chromatolysis and pyknosis in the brain regions. The low dose of parsley 10 g/kg/day exhibited significant effects in neutralizing and reducing the deleterious changes due to Cd exposure during pregnancy on the behavioral activities, neurotransmitters, oxidative stress, and brain neurons morphology of the mice newborns

Molecular genetic analysis of some North African barley germplasms

Isozyme and RAPD markers were used to characterize 29 barley accessions, which were collected from North Africa. In addition, resistance gene sequences were employed to develop molecular markers using RT-PCR approach. High level of polymorphism was found with both RAPD and isozyme markers, where RAPD showed that 60 % of amplified bands were polymorphic. Peroxidase showed three polymorphic loci (7 allelic bands). Isozymes cluster analysis successfully separated the barley accessions into three geographically distinct groups. RAPD investigation demonstrated that Egyptian accessions were grouped into two obvious groups. Moreover, the Tunisian accessions showed no distinct clustering, while high dissimilarities were revealed by the Algerian accessions. In the RT-PCR, from six primer pairs selected, primer pair AF092524P1P2 successfully amplified two specific amplicons of approximately (340 &amp; 220 bp) and (360 &amp; 270 bp), respectively in two Egyptian barley genotypes (El-Awamah and Awlad-Ali). One primer pair DN988165P1P2 gave only one specific amplicon in both barley genotypes of 250 and 270 bp, respectively. The markers developed could be used in improving barley crop by assisting in breeding selection of resistance genotypes.</p

Comparative study of different incision types in inguinal lymphadenectomy: retrospective study

Background: Inguinal lymphadenectomy has always been associated with a high complication rate, mostly related to wound healing. Objectives: We aimed at evaluating the skin excision vertical incision in lowering wound complication rate following inguinal lymphadenectomy. Patients and Methods: Patients underwent inguinal lymphadenectomy for malignant nodal metastasis at the National Cancer Institute, Cairo University, Egypt in the period from January 2017 to December 2020. According to the incision type, we divided them into three groups: Group 1: vertical with vertical skin ellipse (~4cm) excision. Group 2: vertical S-shaped without skin excision.Group 3: transverse incision. We compared the short-term outcome among these groups. Results: Seventy-eight patients included, 27 (34.6%) G1, 27 (34.6% G2), and 24 (30.8%) G3. Complications occurred in a total of 20 cases (25.6% ). Its rate was highest in G3 (37.5% of cases) and least in G1 (14.8%). Flap necrosis was a common serious complication. It least occurred in the G1 Group and most in the G3 Group. No statistical difference was noticed regarding the median operation time, postoperative hospital stay, and median duration before drain removal. Capsular rupture did not occur in G1 patients, occurred only in one case of G2 (3.7%) and 2 cases of G3 ( 8.3%). Despite being statistically insignificant it is very significant oncologically. Conclusions: Vertical elliptical skin wedge excision in inguinal lymphadenectomy provides better surgical field exposure. It avoids direct handling of the tumor; thus is more safe oncologically. It has the least flap necrosis rate among other incision types

The potential therapeutic effect of vitamin D supplementation for management of SARS-COV-2: a systematic review/meta-analysis

Background: vitamin D deficiency has long been associated with decreased immune function and can lead to viral infections. Studies have shown that vitamin D deficiency is associated with an increased risk of COVID-19 infection. However, it is unclear whether treatment with vitamin D can reduce the associated risk of COVID-19 infection. Objective: the current meta-analysis aimed to determine whether vitamin D supplementation had a positive or negative impact on COVID-19 patients. Materials and methods: for this systematic review and meta-analysis, we searched the following databases; CENTERAL, Medline (PubMed), Web of Science, EMBASE and Egyptian Knowledge Bank (EKB, for studies published till February 20, 2022, using key terms. Besides, reference lists of relevant studies were identified. We considered randomized trials (RCTs) and cohort studies as potentially eligible when patients were tested for SARS-CoV-2 infection and received vitamin D supplementation versus a placebo or standard-of-care control. We identified a total of 718 articles, of which 4 RCTs and 3 cohort studies which meet eligible criteria. The seven studies included in our meta-analysis involved 1238 subjects. We considered 7 outcomes to be measured in our meta-analysis which are duration of COVID-19 illness till recovery, need for O2 therapy, need for ICU admission, need for artificial ventilation, fatal prognosis, time to negative PCR and need for hospitalization. Results: vitamin D supplement decreased the period of hospital stay in SARS-CoV2 positive patients. There was no clear protective effect of vitamin D supplementation on the need for oxygen therapy. There was no reduction on need for ICU admission in SARS-CoV2 patients treated with vitamin D supplementation. There was a significant reduction on need for artificial ventilation in patients treated with vitamin D supplementation. Our meta-analysis showed that there is no reduction on fatal prognosis in patients treated with vitamin D supplementation. Only one RCT evaluated time to negative PCR; this study was conducted in India and showed that vitamin D supplementation helped to achieve SARS-CoV-2 RNA negativity in greater proportion of COVID-19 patients with vitamin D supplementation. Conclusion: administration of vitamin D after diagnosis of SARS-CoV-2 infection reduces the period of hospital stay and also reduces the need for artificial ventilation

Minimally Invasive Approach in Surgical Management of Renal Neoplasms National Cancer Institute Experience

BACKGROUND: Minimally invasive nephrectomy is considered a technically challenging procedure requiring a long learning curve to reach acceptable warm ischemia time and perioperative complications. These minimally invasive techniques result in a shorter hospital stay and less post-operative pain. AIM: This study aims to demonstrate the National Cancer Institute experience regarding the benefits of laparoscopic and robot-assisted nephrectomy over open technique. METHODS: This is a retrospective descriptive cohort study including 62 patients with renal masses treated with nephrectomy whether partial, total or radical, 26 cases were treated by minimally invasive techniques (8 robotic and 18 laparoscopic), while 36 cases were treated by open technique. Inclusion criteria were patients between 20 and 70 years with renal neoplasm without renal vein thrombosis, with tumor stage T1 or T2 N0 M0. Exclusion criteria were patients with medical comorbidities that preclude surgical management or minimally invasive techniques and patients refusing surgery in general. RESULTS: Minimally invasive nephrectomy resulted in shorter hospital stay (mean hospital stay was 2.2 days for the minimally invasive group and 3.6 days for the open group) and less post-operative pain than open technique (p &lt; 0.001 and = 0.002, respectively), while open technique resulted in shorter operation time (p = 0.039, mean operation time 147.8 min compared to 184.8 in the minimally invasive group). CONCLUSION: Minimally invasive nephrectomy (laparoscopic and robotic) resulted in less post-operative pain and shorter hospital stay compared to open technique despite consuming longer operation time which may be decreased by improving the learning curve of operating surgeons

Call for emergency action to restore dietary diversity and protect global food systems in times of COVID-19 and beyond: Results from a cross-sectional study in 38 countries

Background: The COVID-19 pandemic has revealed the fragility of the global food system, sending shockwaves across countries\u27 societies and economy. This has presented formidable challenges to sustaining a healthy and resilient lifestyle. The objective of this study is to examine the food consumption patterns and assess diet diversity indicators, primarily focusing on the food consumption score (FCS), among households in 38 countries both before and during the first wave of the COVID-19 pandemic. Methods: A cross-sectional study with 37 207 participants (mean age: 36.70 ± 14.79, with 77 % women) was conducted in 38 countries through an online survey administered between April and June 2020. The study utilized a pre-tested food frequency questionnaire to explore food consumption patterns both before and during the COVID-19 periods. Additionally, the study computed Food Consumption Score (FCS) as a proxy indicator for assessing the dietary diversity of households. Findings: This quantification of global, regional and national dietary diversity across 38 countries showed an increment in the consumption of all food groups but a drop in the intake of vegetables and in the dietary diversity. The household\u27s food consumption scores indicating dietary diversity varied across regions. It decreased in the Middle East and North Africa (MENA) countries, including Lebanon (p \u3c 0.001) and increased in the Gulf Cooperation Council countries including Bahrain (p = 0.003), Egypt (p \u3c 0.001) and United Arab Emirates (p = 0.013). A decline in the household\u27s dietary diversity was observed in Australia (p \u3c 0.001), in South Africa including Uganda (p \u3c 0.001), in Europe including Belgium (p \u3c 0.001), Denmark (p = 0.002), Finland (p \u3c 0.001) and Netherland (p = 0.027) and in South America including Ecuador (p \u3c 0.001), Brazil (p \u3c 0.001), Mexico (p \u3c 0.0001) and Peru (p \u3c 0.001). Middle and older ages [OR = 1.2; 95 % CI = [1.125–1.426] [OR = 2.5; 95 % CI = [1.951–3.064], being a woman [OR = 1.2; 95 % CI = [1.117–1.367], having a high education (p \u3c 0.001), and showing amelioration in food-related behaviors [OR = 1.4; 95 % CI = [1.292–1.709] were all linked to having a higher dietary diversity. Conclusion: The minor to moderate changes in food consumption patterns observed across the 38 countries within relatively short time frames could become lasting, leading to a significant and prolonged reduction in dietary diversity, as demonstrated by our findings
