Constructing and Norming Arabic Screening Tool of Auditory Processing Disorders: Evaluation in a Group of Children at Risk for Learning Disability

The purposes of this study were to develop and provide the normative data of Arabic screening tool for screening the children with auditory processing disorders: an Arabic version of Adaptive Auditory Speech Test (AAST) in quiet for screening the peripheral hearing in dB SPL units; an Arabic AAST in binaural noise for screening the temporal interaction deficit: listening speech in binaural noise in dB SNR units, then teetaatoo test with a five subtests for screening the Modern Standard Arabic language phonemes identification ability. Participants included 338 children aged from 5 to 7 years old (138 males, 200 females; mean age = 6.08 years with standard deviation = 0.8) from a regular nursery school which called Baroot Summer Club in Beni-Suef in Egypt were recruited to participate in the study. According to the calculated Norms of AAST in quiet and through a meeting with the teachers of children in the nursery school, 129 children were sift out with no hearing loss, negative histories of neurological disorders, head trauma or surgery, dizziness, and attention deficit disorder/attention deficit hyperactivity disorder. 129 children were screened for listening in binaural noise using the Arabic AAST in binaural noise, then the left 94 children, because 35 children couldn`t complete the testing, was screened for phonemes identification ability using teetaatoo test(the five sub tests). For the AAST in quiet, 21 to 33 dB SPL is the normal range of the hearing peripheral loss, especially, for the AAST in binaural noise, there are three different norms; -9 to -13 dB SNR is the normal range of children aged 5 years old, -10 to -13 dB SNR is the normal range of children aged 6 years old, and -10 to -14 dB SNR is the normal range of children aged 7 years old. Finally, for the five subtests (teetaatoo): > 85% (correct answers) is the normal percentage of the Cons-A, >62& (correct answers) is the normal percentage of the Cons-B1, >76% is the normal percentage of the Cons-B2, >63% (correct answers) is the normal percentage of the Cons-B3, and 84% (correct answers) is the normal percentage of the Vow-A. Further, according to the previous norms, 23 children represent 17,8% from the whole sample (N=129) with a normal speech recognition threshold have scored abnormally on the speech listening in bin-noise (AAST in bin-noise) or on at least one subtest from teetaatoo subtests and were considered at risk for learning disability because of their scores on a SIFTER

Determining the most appropriate printing techniques for digital printing to achieve printing quality of Teslin polymers

Some documents in the Arab Republic of Egypt face a great challenge, which is the problem of short life span, and it is worth noting here that the global trend and also in the Arab Republic of Egypt recently is moving towards the use of polymers as an alternative to traditional paper materials in many important documents, and therefore the research has addressed the possibility of printing on raw materials. Teslin polymers, facing many challenges, including print quality when printed on any of the digital printing techniques in terms of determining the most appropriate digital techniques for printing on plastic Teslin material to obtain the required print quality by measuring both (Lab values of colour, density, dot gain and trapping).

Polymorphism RS2227306 in the Interleukin 8 gene and its relation to bronchial asthma: Review article

Background: Allergy symptoms such as wheezing, breathlessness, and coughing are all symptoms of asthma, which is a long-term respiratory condition characterized by inflammation and reversible airway blockage. If you're a child or young adult, asthma is the most common long-term condition, with more severe symptoms. The CXC chemokine superfamily includes the Interleukin 8 (IL-8) chemokine. T lymphocytes, neutrophils, and mast cells are all chemotactic cytokines that IL-8 attracts in the body. A polymorphism in the promoter region of IL-8 - 781C/T (rs2227306) has been found to be associated with an elevated level of the cytokine IL-8. There is a gene in the first intron of the IL-8 - 781C/T (rs2227306) that has been reported to aid in both gene transcription and gene regulation.Objective: The aim of the present review was to study polymorphism RS2227306 in the interleukin 8 gene and its relation to bronchial asthma.Conclusion: IL8 polymorphism rs2227306 has the potential to be utilized as a marker in interpretation of assessment of severity of asthma

Evaluation Of Facial Soft Tissue Changes In Excessive Gingival Display Cases After Le Forte I Maxillary Impaction Surgery Using 3D Facial Surface Laser Scanner

Introduction: Facial soft tissue changes in relation to hard tissue movements after orthognathic surgery cases is always of concern to patients , surgical and orthodontics teams. The aim of the present study was to assess facial soft tissue changes and stability using 3D facial laser scanner after orthognathic surgery Le Forte I maxillary impaction in excessive gingival display patients. Methods: The subjects consisted of 12 patients with skeletal vertical maxillary excess (VME) causing an aesthetic concern to the patients in the form of “Gummy smile”, who underwent LeFort I osteotomy with maxillary impaction, Three-dimensional images of the patients were acquired with a 3D laser scanner preoperatively and postoperatively. The changes in facial soft tissue were detected using a colour coded map for analysis. Results: Significant change was recorded in the upper lip, alar base, nasolabial fold and nasal tip areas, without specification of this change in direction. Conclusions: The 3D images captured using the laser scanner in this study can be a useful tool for communication with both patients and professionals but cannot be relied upon solely for accurate analysis of the facial soft tissue changes. The colour coded map analysis cannot be relied upon solely as a method of analysis as it lacks an important aspect of the change which is the direction

PROTECTIVE EFFECT OF MORINGA PEREGRINA LEAVES EXTRACT ON ACETAMINOPHEN - INDUCED LIVER TOXICITY IN ALBINO RATS.

Background: Acetaminophen is a common antipyretic drug but at overdose can cause severe hepatotoxicity that may further develop into liver failure and hepatic centrilobular necrosis in experimental animals and humans. This study was undertaken to assess the ameliorative role of Moringa peregrina leaves extract against acetaminophen toxicity in rats. Materials and methods: Induction of hepatotoxicity was done by chronic oral administration of acetaminophen (750 mg/kg bwt) for 4 weeks. To study the possible hepatoprotective effect, Moringa peregrina leaves extract (200 mg/kg bwt) or Silymarin (50 mg/kg bwt) was administered orally, for 4 weeks, along with acetaminophen. Results: acetaminophen significantly increased serum liver enzymes and caused oxidative stress, evidenced by significantly increased tissue malondialdehyde, glutathione peroxidase, hepatic DNA fragmentation, and significant decrease of glutathione and antioxidant enzymes in liver, blood and brain. On the other hand, administration of Moringa peregrina leaves extract reversed acetaminophen-related toxic effects through: powerful malondialdehyde suppression, glutathione peroxidase normalization and stimulation of the cellular antioxidants synthesis represented by significant increase of glutathione, catalase and superoxide dismutase in liver, blood and brain, besides, DNA fragmentation was significantly decreased in the liver tissue. Conclusion: acetaminophen induced oxidative damage can be improved by Moringa peregrina leaves extracttreatment, due to its antioxidant potential

Comparative study of the chemical composition and anti-proliferative activities of the aerial parts and roots of Apium graveolens L. (celery) and their biogenic nanoparticles

Apiaceae plants are multipurpose folk remedies and bioactive foods that show a remarkable ability to biosynthesize a large number of secondary metabolites with antitumor and chemopreventive potential. Among the various members of the Apiaceae, celery (Apium graveolens L.) has long been used as a popular edible and medicinal plant owing to its plentiful health benefits and nutraceutical properties; however, the anticancer potential of this important species has been seldom studied, mostly focusing on its seeds. Therefore, this work was designed to delve into the chemical composition and anti-proliferative potential of the total ethanolic extracts of the aerial parts (TEEAGA) and roots (TEEAGR) of A. graveolens var. dulce (Mill.) Pers. as well as their green synthesized silver nanoparticles (AgNPs). In general, both TEEAGA and TEEAGR exhibited moderate to potent inhibitory activities against human liver (HepG-2), colon (Caco-2), and breast (MCF-7) cancer cell lines, with interesting IC50 profiles [(41.37 ± 0.12, 27.65 ± 0.27, and 9.48 ± 0.04 μg/mL) and (11.58 ± 0.02, 7.13 ± 0.03, and 6.58 ± 0.02 μg/mL), respectively] as compared with doxorubicin, while more pronounced anti-proliferative effects were observed for their biogenic AgNPs, which showed IC50 values ranging between 25.41 ± 0.16 and 1.37 ± 0.03 μg/mL. Moreover, HPLC‒HESI‒HRMS-based metabolomics analysis of both extracts showed the presence of a varied group of secondary metabolites, including flavonoids, phenylpropanoids, phthalides, coumarins, and sesquiterpenes that further displayed moderate to promising binding affinities to the active site of cyclin G-associated kinase (GAK), particularly graveobioside A, graveobioside B, and celeroside C, suggesting their possible contribution as GAK modulators to the anti-proliferative potential of celery. These findings can help broaden future research on the utilization of different parts of celery and their NPs as functional foods and medicines in cancer chemoprevention and therapy

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.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication
