COVID-19 related knowledge and practice and barriers that hinder adherence to preventive measures among the Egyptian community. An epidemiological study in Upper Egypt.

BACKGROUND This study aims to assess COVID-19 related knowledge and practice among the Egyptians in Upper Egypt and to identify barriers that hinder adherence to these preventive measures. DESIGN AND METHODS We conducted a cross-sectional study using a structured questionnaire. Data was collected from 21 to 30 August 2020, via both online survey and personal interviews using a non-probability self-nominated sample. RESULTS A total of 731 participants completed the questionnaire. The mean age was 32.1± 2.1 and 64.3% were females. The main sources of knowledge were, Internet and Social Media followed by TV then family and friends. More than 96% of the respondents knew the origin, nature, the main symptoms, and the modes of transmission of COVID-19, however, 37.6% of them thought that COVID-19 patients must develop symptoms. 75.8% and 73.6% of the participants respectively covered their nose and mouth during sneezing and washed their hands regularly, 65.4% wore masks in crowded places, while only 31.1% and 30% of them respectively avoided touching their faces or shaking hands with friends. Knowledge and practice were positively correlated and both were linked to younger age and higher education and the female gender was also a predictor of better practice. The most common perceived barriers to adherence to preventive measures were feeling uncomfortable, forgetfulness then financial causes. CONCLUSIONS the study subjects were aware of COVID-19 and its preventive measures however adherence to some of these measures was not prevalent amongst them, indicating an urgent need of addressing and targeting barriers that hinder adherence to COVID-19 preventive measures in the future policies to prevent the spread of COVID-19 in Egypt.
CO2 emission, oil consumption and production, economic growth in MENAP countries: ARDL and ANOVA methods

This paper examines the relationship between oil consumption, oil production, CO2 consumption and economic growth in MENAP countries, using the autoregressive distributed lag (ARDL) bounds testing approach, Toda and Yamamotos' non-causality and ANOVA methods. According to our results, oil consumption has a positive impact on economic growth in Qatar and Saudi Arabia both in the short-run and the long-run, but only in the long-run in Lebanon and Tunisia. Toda and Yamamoto causality results show evidence of a unidirectional causality relationship from GDP to CO2 emissions for Bahrain, Egypt, Morocco, Oman, Syria and Tunisia; a unidirectional causality relationship from CO2 emissions to GDP for Pakistan and Yemen; and a bi-directional causality relationship for Jordan, Kuwait, Lebanon and Qatar. The evidence of bi-directional causality between GDP and oil production was obtained for Algeria, Bahrain, Iran, Egypt, Kuwait, Libya, Oman, Qatar, Saudi Arabia, UAE, Oman and Syria.

Comparison of antegrade and retrograde ureterolithotripsy for proximal ureteral stones: a systematic review and meta-analysis

Background Antegrade percutaneous ureterolithotripsy (URSL) could be a treatment option for large and/or impacted proximal ureteral stones, which are difficult to treat. To review the current approach and treatment outcomes and to compare the efficacy of retrograde and antegrade URSL for large proximal ureteral stones, we evaluated the unique perspectives of both surgical modalities. Methods This systematic literature review and meta-analysis was performed in July 2020. Articles on human studies and treatment of ureteral stones with URSL were extracted from the PubMed, MEDLINE, Embase, Cochrane Library, Scopus, and the Japan Medical Abstracts Society databases without any language restrictions. The risks of bias for randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) were assessed using the Cochrane risk of tool and the Risk of Bias in Non-randomized Studies- of Interventions tool, respectively. Results A total of 10 studies, including seven RCTs and three non-RCTs, were selected for the analysis; 433 and 420 cases underwent retrograde and antegrade URSL, respectively. The stone-free rate (SFR) was significantly higher in antegrade URSL than in retrograde URSL (SFR ratio: 1.17, 95% CI: 1.12–1.22; P<0.001), while the hospital stay was significantly longer in antegrade URSL than in retrograde URSL (standardized mean difference: 2.56, 95% CI: 0.67–4.46; P=0.008). There were no significant differences in the operation time and the overall complication rate between the two approaches. Conclusions Despite the heterogeneity of data and bias limitations, this latest evidence reflects real practice data, which may be useful for decision making.
Short-term effects of delivery methods on postpartum pelvic floor function in primiparas: a retrospective study.

BACKGROUND The present study sought to investigate the short-term effects of different delivery methods on postpartum pelvic floor function in Chinese primiparas. METHODS Primiparous women who delivered a full-term, cephalic, singleton infant at our hospital between January 1, 2018 and August 15, 2019 were recruited into this study. All women underwent pelvic floor function screening at 6-8 weeks postpartum. Tests included postpartum Pelvic Organ Prolapse Quantification (POP-Q) score, incidence of urinary incontinence, pelvic floor muscle (PFM) strength, and Pelvic Floor Distress Inventory Questionnaire-Short Form 20 (PFDI-20) score. RESULTS A total of 284 postpartum women were recruited into the study. Of the participants, 147 had undergone vaginal delivery, 37 had undergone intrapartum cesarean delivery (ICD), and 100 had undergone elective cesarean delivery (ECD). Points Aa, Ba, Ap, and Bp showed a greater degree of prolapse in the vaginal delivery group than in the ECD group (P≤0.05). UI was less prevalent in ECD group relative to the vaginal delivery group (P≤0.05). Tonic PFM contraction was weaker in the vaginal delivery group than in the ECD and ICD groups (P≤0.05). Significant differences were also observed between the vaginal delivery group and the ECD group with respect to PFDI-20 scores (P≤0.05). CONCLUSIONS Compared with vaginal delivery, ECD was strongly linked to a lower risk of pelvic organ prolapse (POP) and UI, stronger tonic PFM strength, and lower PFDI-20 scores. ECD confers relatively better protection against pelvic floor dysfunction (PFD) than does ICD.
Evolution of Online Health-Related Information Seeking in France From 2010 to 2017: Results From Nationally Representative Surveys

Background Given the rapid ongoing progression of the internet and increase in health information available from disparate online sources, it is important to understand how these changes impact online health information-seeking behavior of the population and the way of managing one’s health. Objective This paper aims at describing the evolution of internet use as a source of health information between 2010 and 2017, as well as the characteristics of online health information seekers, topics of interest, sources of information, and trust in retrieved information and potential impact on behavior. Methods Data from the French nationally representative surveys Health Barometers were used (N=4141 in 2010, 4811 in 2014, and 6255 in 2017). Evolutions over time were assessed using chi-square tests. Associations with sociodemographic characteristics and health status were evaluated using logistic regression models. Results The use of the internet as a source of health information rose between 2010 and 2014 (from 37.3% to 67.9%, P<.001) but decreased significantly in 2017 (60.3%, P<.001). Overall, the profile of health information seekers compared with nonseekers did not change over time. They were more likely to be women, to be younger, to have a higher educational level, to have a higher household income, and to be executives. Between 2014 and 2017, the proportion of those who did not pay attention to the source of information significantly increased to reach 39.7% (P<.001). In 2017 as in 2014, general health-related websites remained the first source of information (38.6%) while institutional websites were the third source (8.1%). Most information seekers trusted the information found online in 2010 (more than 80%), with a slight decrease between 2014 and 2017 (P=.048). Among individual characteristics, trust in the information was the main determinant of the way of managing one’s health (odds ratio 4.06, 95% CI 3.26-5.06). Conclusions After a rapid growth in the internet use for seeking health information in the 2010 to 2014 period, a decrease was recorded in 2017, in parallel with a decrease in trust in the quality and reliability of information found online. These findings underline the need for public health authorities to increase citizens’ eHealth literacy and to provide alternative trustworthy sources combining the popularity and accessibility of general health information websites.
Biosynthesis of silver nanoparticles using lavender leaf and their applications for catalytic, sensing, and antioxidant activities

Abstract The present report summarizes an eco-friendly approach for the biosynthesis of silver nanoparticles (AgNPs) using the leaf extract of lavender. Initially, the synthesis of AgNPs was visually observed by the appearance of a wine red color. The optical property, morphology, and structure of as-synthesized AgNPs were characterized by UV-visible spectroscopy, dynamic light scattering, transmission electron microscopy, and X-ray diffraction analyses. All characterization data revealed the formation of crystalline and spherical AgNPs (Ag/Ag2O) with size around 10–80 nm at λmax=440 nm. The surface-modified AgNPs showed an effective catalytic activity toward the reduction of 4-nitrophenol to 4-aminophenol, optical sensing of H2O2, and antioxidant activity against 1,1-diphenyl-2-picrylhydrazyl. The experimental approach is simple, facile, economical, and easily reproducible without any use of toxic chemicals, and opens up new scope for future biotechnology applications.
Liming an acid soil treated with diverse silicon sources: Effects on silicon uptake by sugarcane (Saccharum spp. hybrids)

ABSTRACT Highly weathered soils are typically acid, with low plant-available silicon (Si), and may also be high in soluble aluminum (Al). We tested whether pre-liming an acid soil prior to silicate fertilizer application improved Si uptake by sugarcane (Saccharum spp. hybrids), feasibly through elimination of reactive Al. Three trials with potted sugarcane were grown in an acid soil. Treatments included 11 different Si sources and 1- or 3-month pre-liming periods. Soil and plant tissue Si content and yield were determined. Pre-liming for a 1- or 3-month period did not increase plant Si uptake and reduced available soil Si throughout. Alkaline Si sources produced significantly more plant-available Si and greater plant uptake than non-alkaline sources. Silicon and lime treatments did not significantly increase yield. We conclude that pre-liming an acid soil before Si application is unlikely to significantly improve Si uptake by sugarcane.
Potential role of cannabidiol in Parkinson’s disease by targeting the WNT/β-catenin pathway, oxidative stress and inflammation

Parkinson’s disease (PD) is a major neurodegenerative disease (ND), presenting a progressive degeneration of the nervous system characterized by a loss of dopamine in the substantia nigra pars compacta. Recent findings have shown that oxidative stress and inflammation play key roles in the development of PD. However, therapies remain uncertain and research for new treatment is of the utmost importance. This review focuses on the potential effects of using cannabidiol (CBD) as a potential therapeutic strategy for the treatment of PD and on some of the presumed mechanisms by which CBD provides its beneficial properties. CBD medication downregulates GSK-3β, the main inhibitor of the WNT/β-catenin pathway. Activation of the WNT/β-catenin could be associated with the control of oxidative stress and inflammation. Future prospective clinical trials should focus on CBD and its multiple interactions in the treatment of PD.
Global coordination of metabolic pathways in Escherichia coli by active and passive regulation

Microorganisms adjust metabolic activity to cope with diverse environments. While many studies have provided insights into how individual pathways are regulated, the mechanisms that give rise to coordinated metabolic responses are poorly understood. Here, we identify the regulatory mechanisms that coordinate catabolism and anabolism in Escherichia coli. Integrating protein, metabolite, and flux changes in genetically implemented catabolic or anabolic limitations, we show that combined global and local mechanisms coordinate the response to metabolic limitations. To allocate proteomic resources between catabolism and anabolism, E. coli uses a simple global gene regulatory program. Surprisingly, this program is largely implemented by a single transcription factor, Crp, which directly activates the expression of catabolic enzymes and indirectly reduces the expression of anabolic enzymes by passively sequestering cellular resources needed for their synthesis. However, metabolic fluxes are not controlled by this regulatory program alone; instead, fluxes are adjusted mostly through passive changes in the local metabolite concentrations. These mechanisms constitute a simple but effective global regulatory program that coarsely partitions resources between different parts of metabolism while ensuring robust coordination of individual metabolic reactions.
Molecular phylogeny and species delimitation of the genus Tonkinacris (Orthoptera, Acrididae, Melanoplinae) from China

Tonkinacris is a small group in Acrididae. While a few species were occasionally sampled in some previous molecular studies, there is no revisionary research devoted to the genus. In this study, we explored the phylogeny of and the relationships among Chinese species of the genus Tonkinacris using the mitochondrial COI barcode and the complete sequences of ITS1 and ITS2 of the nuclear ribosomal DNA. The phylogeny was reconstructed in maximum likelihood and Bayesian inference frameworks, respectively. The overlap range between intraspecific variation and interspecific divergence was assessed via K2P distances. Species boundaries were delimitated using phylogenetic species concept, NJ tree, K2P distance, the statistical parsimony network as well as the GMYC model. The results demonstrate that the Chinese Tonkinacris species is a monophyletic group and the phylogenetic relationship among them is (T. sinensis, (T. meridionalis, (T. decoratus, T. damingshanus))). While T. sinensis, T. meridionalis and T. decoratus were confirmed being good independent species strongly supported by both morphological and molecular evidences, the validity of T. damingshanus was not perfectly supported by molecular evidence in this study.
Development of Chinese odor identification test

Background Olfactory dysfunction significantly reduces quality of life, with a prevalence as high as 20% in the general adult population. Odor identification (OI) tests are culturally dependent and widely used in clinical and epidemiological evaluations of olfaction. We aimed to develop a Chinese odor identification test (COIT) based on the Sniffin’ Sticks identification test. Methods Patients (n=60) with olfactory disorders and healthy controls (n=404) were recruited in the Smell and Taste Center of a tertiary-care university hospital. Unfamiliar odors in the Sniffin’ Sticks identification test were replaced to create a 16-item COIT, which was validated with a simplified Chinese version of the Cross-culture Smell Identification Test (CC-SIT) and Sniffin’ Sticks. A test-retest reliability of COIT was also conducted. Results Six odors with a correct recognition rate <75% were replaced with familiar odors for Chinese. The COIT score significantly correlated with both Sniffin’ Sticks (r=0.755 P<0.0001) and CC-SIT score (r=0.7462 P<0.0001). Based on the testing results of an additional 120 subjects, we concluded that scores of 12–16, 7–11, and 0–6 corresponded to normosmia, hyposmia, and anosmia, respectively. The 3-month test-retest-reliability coefficient was as high as 0.83. Conclusions The COIT is an effective tool for assessing olfactory function in the Chinese population.
Pediatric sarcoma survivorship: A call for a developmental cascades approach

Abstract Survivors of pediatric sarcomas often experience greater psychological and psychosocial difficulties than their non-afflicted peers. We consider findings related to poorer outcomes from a developmental cascade perspective. Specifically, we discuss how physical, neurocognitive, psychological, and psychosocial costs associated with pediatric sarcomas and their treatment function transactionally to degrade well-being in long-term pediatric sarcoma survivors. We situate the sarcoma experience as a broad developmental threat – one stemming from both the presence and treatment of a life-imperiling disease, and the absence of typical childhood experiences. Ways in which degradation in one developmental domain spills over and effects other domains are highlighted. We argue that the aggregate effect of these cascades is two-fold: first, it adds to the typical stress involved in meeting developmental milestones and navigating developmental transitions; and second, it deprives survivors of crucial coping strategies that mitigate these stressors. This position suggests specific moments of intervention and raises specific hypotheses for investigators to explore.
The longitudinal association between loneliness and depressive symptoms in the elderly: a systematic review.

OBJECTIVE Loneliness and the onset of depression in old age are growing problems related to the greater life expectancy nowadays. This review investigated the longitudinal association between loneliness and depressive symptoms in the elderly. DESIGN A comprehensive search was conducted using three databases (Scopus, PsycInfo, and PubMed) combing for empirical studies published up until July 2020. A total of 4.549 abstracts and 221 full-text articles were assessed. Three authors independently reviewed titles and abstracts; disagreements were resolved by consensus. RESULTS Ten studies were included in the final review. We identified two categories of studies based on the outcome considered in each article: 1) the longitudinal effect of loneliness on depressive symptoms and 2) the clinical course of depression and its association with loneliness. All the articles reported a significant and positive association between loneliness and depressive symptoms in their longitudinal design research, ranging from an odds ratio of 0.41 to 17.76. The heterogeneity regarding the effect size in the analyses can be explained by the multifactorial design implemented by most of the studies included. CONCLUSIONS Future research should investigate the moderators' role and how it may influence the longitudinal association between loneliness and depression over the years.
The Current Management of Hepatorenal Syndrome–Acute Kidney Injury in the United States and the Potential of Terlipressin

Acute kidney injury (AKI) in the setting of cirrhosis (hepatorenal syndrome [HRS]–AKI) is a severe and often fatal complication of end‐stage liver disease. The goals of treatment are to reverse renal failure and prolong survival in patients who are critically ill. However, interventions have limited efficacy, and mortality rates remain high. In the United States, the mainstay of pharmacologic therapy consists of the off‐label use of vasoconstrictive agents in combination with plasma expanders, a strategy that produces modest effects. Liver transplantation is the ultimate solution but is only an option in a minority of patients because contraindications to transplantation are common and organ availability is limited. Renal replacement therapy is a temporary option but is known to confer an extremely poor short‐term prognosis in patients with HRS‐AKI and at best serves as a bridge to liver transplantation for the minority of patients who are transplantation candidates. The high mortality rate associated with HRS‐AKI in the United States is a reflection of the suboptimal standard of care. Improved therapeutic options to treat HRS‐AKI are sought. Terlipressin is a drug approved in Europe for treatment of HRS‐AKI and supported by recommendations for first‐line therapy by some liver societies and experts around the world. This review article will discuss the substantial unmet medical need associated with HRS‐AKI and the potential benefits if terlipressin was approved in the United States.
Temporal trends in the quality of deceased donor kidneys and kidney transplant outcomes in Europe: an analysis by the ERA-EDTA Registry

Abstract Background We investigated 10-year trends in deceased donor kidney quality expressed as the kidney donor risk index (KDRI) and subsequent effects on survival outcomes in a European transplant population. Methods Time trends in the crude and standardized KDRI between 2005 and 2015 by recipient age, sex, diabetic status and country were examined in 24 177 adult kidney transplant recipients in seven European countries. We determined 5-year patient and graft survival probabilities and the risk of death and graft loss by transplant cohort (Cohort 1: 2005–06, Cohort 2: 2007–08, Cohort 3: 2009–10) and KDRI quintile. Results The median crude KDRI increased by 1.3% annually, from 1.31 [interquartile range (IQR) 1.08–1.63] in 2005 to 1.47 (IQR 1.16–1.90) in 2015. This increase, i.e. lower kidney quality, was driven predominantly by increases in donor age, hypertension and donation after circulatory death. With time, the gap between the median standardized KDRI in the youngest (18–44 years) and oldest (>65 years) recipients widened. There was no difference in the median standardized KDRI by recipient sex. The median standardized KDRI was highest in Austria, the Netherlands and the Basque Country (Spain). Within each transplant cohort, the 5-year patient and graft survival probability were higher for the lowest KDRIs. There was no difference in the patient and graft survival outcomes across transplant cohorts, however, over time the survival probabilities for the highest KDRIs improved. Conclusions The overall quality of deceased donor kidneys transplanted between 2005 and 2015 has decreased and varies between age groups and countries. Overall patient and graft outcomes remain unchanged.
Tissue-resident-like CD4+ T cells secreting IL-17 control Mycobacterium tuberculosis in the human lung

T cell immunity is essential for the control of tuberculosis (TB), an important disease of the lung, and is generally studied in humans using peripheral blood cells. Mounting evidence, however, indicates that tissue-resident memory T cells (Trms) are superior at controlling many pathogens, including Mycobacterium tuberculosis (M. tuberculosis), and can be quite different from those in circulation. Using freshly resected lung tissue, from individuals with active or previous TB, we identified distinct CD4+ and CD8+ Trm-like clusters within TB-diseased lung tissue that were functional and enriched for IL-17–producing cells. M. tuberculosis–specific CD4+ T cells producing TNF-α, IL-2, and IL-17 were highly expanded in the lung compared with matched blood samples, in which IL-17+ cells were largely absent. Strikingly, the frequency of M. tuberculosis–specific lung T cells making IL-17, but not other cytokines, inversely correlated with the plasma IL-1β levels, suggesting a potential link with disease severity. Using a human granuloma model, we showed the addition of either exogenous IL-17 or IL-2 enhanced immune control of M. tuberculosis and was associated with increased NO production. Taken together, these data support an important role for M. tuberculosis–specific Trm-like, IL-17–producing cells in the immune control of M. tuberculosis in the human lung.
