The senses perceive the meanings of graphic processors on smartphones

Perception is a processing of information that comes from the senses to the brain, so that the complex central nervous system determines, organizes and interprets information to understand the world around us, and one of the most important senses is the sense of sight, which includes external visual vision, mental vision, imaginative and internal emotional, through which the human mind adds The meaning depends on the sensory perceptions that it receives, whatever they are. When you see a shape, the eye keeps searching for the meaning of its parts. Visual perception is the ability to interpret the surrounding environment, by interpreting information within visible light. Aesthetic perception is a process of mental activity that takes place after receiving signals emitted from graphics. Through the senses, which is the ability to feel the artwork, whether plastic works or videos loaded on mobile phones, which have become apparent to a large segment of society in displaying and watching artworks through mobile phones, which are affected by various factors on which the perception of the senses of the recipient who enjoys a prior visual culture depends.

Role of Prostaglandin E2 in Cirrhotic Patients with Spontaneous Bacterial Peritonitis

Background: Spontaneous bacterial peritonitis (SBP) is the most frequent bacterial infection in patients who suffer from liver cirrhosis and ascites. Prostaglandin E2 (PGDE2) is considered a simple and accurate tool for diagnosing systemic inflammation and has a relevant impact on prognosis in cirrhotic patients.Objective: We tried to detect the role of PGDE2 in serum and ascitic fluid as a diagnostic marker for eradication of SBP.Patients and methods: This clinical-based prospective cohort study involved patients with liver cirrhosis, ascites and spontaneous bacterial peritonitis referred to the Internal Medicine Department, Faculty of Medicine, Zagazig University during the period from June 2020 to March2021. Patients with ascites were divided equally into: (a) case group included cirrhotic patients with SBP); and (b) control group included cirrhotic patients without SBP. All patients were subjected to complete clinical and laboratory examination. Serum and ascitic PGDE2 were estimated before and after five days of treatment. Results: There was statistically significant difference between the studied groups regarding Child score and presence of HCC. Serum and ascitic PGDE2 was elevated in all cirrhotic groups; both of case and control had more than normal. However, PGDE2 level was lower in case group before treatment in comparison with control group, and after treatment PGDE2 levels was elevated.Conclusion: Serum and ascitic fluid PGDE2 can be used as a diagnostic marker for SBP diagnosis and eradication. Serum PGDE2 is preferred due to its less invasiveness and minimal risk of complications

Serum Soluble CD93 as a Biomarker of Asthma Exacerbation in Children

Background: Asthma is considered one of the most prevalent diseases affecting over than 300 million individuals worldwide. Soluble CD93 was normally detected in human plasma and induced by the inflammatory mediators TNF-α and LPS, suggesting that physiologic pathways trigger the cleavage event. Objective: To evaluate the diagnostic value of serum soluble CD93 level in acute asthma exacerbation in children and to find if there is a relation between serum level of soluble CD93 and acute exacerbations of asthma among children. Patients and Methods: Our study included 30 patients who were diagnosed as acute asthmatics with acute exacerbation (diagnosed and classified according to GINA 2018) as group I. Group Π, which included the same 30 patients after receiving treatment and relieve of symptoms by clinical examination as well as routine laboratory investigations that confirmed their healthy state. Plasma sCD93 concentration using ELISA (at the time of exacerbation and repeated on the follow up day) and spirometry were done. Results: Regarding severity (after classification of cases into intermittent, mild and moderate), there was no statistical significance difference in severity either pre- or post-treatment. Regarding sCD93, there was statistical significance reduction in sCD 93 level post-treatment compared to pre-treatment in all cases. There were no statistical significance relation between gender, residence and family history and sCD 93 levels among the studied group. There were no statistical significance relation between WBCs and x-ray and sCD 93 levels among the studied group. Conclusion: sCD93 was not affected by gender or age and did not affect by reliever or controller medications. sCD93 showed a modest decrease in the controlled stage of asthma, which allowed to interpret its role as inflammatory biomarker

Assessment of level of serum cardiac troponin T in neonates with respiratory distress syndrome

Background: One of the most prevalent reasons for admission to neonatal intensive care units (NICUs) is respiratory distress syndrome (RDs). When myocardial cells are damaged, cardiac troponin I (cTnT) is released as a biomarker of myocardial damage, which is very specific and sensitive.Objective: To determine the level of cTnT in preterm infants who have respiratory distress syndrome as a marker of cardiac dysfunction.Patients and Methods: This study was carried as a case-control trial on forty preterm infants, 20 patients of respiratory distress syndrome at neonatal intensive care unit as a group I, 20 apparently healthy newborns as a control group. Serum cardiac troponin T level sample was taken on the 3rd day of delivery.Results: A statistically significant difference in blood troponin was found between the groups tested, with a negative connection between serum troponin and gestational age, length, and APGAR scores at the first and fifth minutes of life. Respiratory rate and serum troponin were found to have a statistically significant connection. Any one of the echocardiographic measures had a statistically significant positive connection with serum troponin. Serum troponin was able to diagnose respiratory distress syndrome with cutoff ≥ 93.5 ng/mL with the area under the curve, Positive predictive value: 83.33% Positive predictive value: 83.33% Negative predictive value: 100 percent Accuracy: 90%.Conclusion: Cardiac troponin T can be used to detect cardiac dysfunction in ill newborns, especially in centers that do not have in-house echocardiography

Fraudulence Risk Strategic Assessment of Processed Meat Products

 A total of 450 samples of different meat products (luncheon chicken, luncheon meat, sausage, beef burger, minced meat, and kofta) were examined. Fifty samples of each type of product were collected from different supermarkets in Assiut City. All of the samples were analysed by different microscopy techniques (light, fluorescence, histochemical microscopy, and scanning electron microscopy (SEM)) for the detection of meat adulteration. Haematoxylin-eosin (HE) staining was used for general histological examinations. Different histochemical techniques were used to stain paraffinised sections. The adulterated tissues detected were the nuchal ligament, large elastic blood vessels, muscular artery, elastic fibers, lung, cardiac muscle fibers, tendon, spongy bone, bone of immature animals, adipose tissue, cartilage (hyaline and white fibrocartilage), and smooth muscle of visceral organs. SEM detected contamination of the minced meat by bacteria and yeast. Fluorescence microscopy was used as an effective method for the detection of bone and cartilage. Interestingly, the stained acidophilic cytoplasm of skeletal muscle changed to basophilic, and the skeletal muscle was suspected to be diseased. The findings of the present work provide qualitative evaluations of the detection of unauthorised tissues in different meat products using different effective histological techniques

Case Report: Autochthonous Case of Human Visceral Leishmaniasis in the West Bank, Palestine

Human visceral leishmaniasis (HVL) is a parasitic disease infecting children in the Mediterranean region. Here,weportray a case of a 2-year-old child with an epidemiological description of the situation surrounding the case. The patient was suffering from recurrent fever, weakness and abdominal discomfort associated with loss of appetite. Routine blood investigations showed pancytopenia, whereas examination revealed hepatomegaly. A diagnosis of HVL was made by demonstrating amastigotes in a Giemsa-stained smear from a bone marrow aspirate followed by genotyping by PCR and sequencing. In conclusion, early detection of VL infection followed by appropriate treatment protocols is essential to saving the patient

Effect of intensive phototherapy on T and B lymphocyte function in neonatal jaundice

Background: Jaundice is one of the most common problems that affect newborns in the first few days of life. Approximately 60% of full-term and 80% of the preterm newborn may develop neonatal jaundice. Although neonatal jaundice is of physiological type in most of these cases, some cases may have elevated serum bilirubin levels which, if not treated, may lead to bilirubin encephalopathy and subsequently bilirubin induced neurological dysfunction (BIND). Objective: This study aimed to evaluate the effect of intensive phototherapy on B and T cells by measuring the percentages of CD19+, CD4+ and CD8+ lymphocytes subsets in newborns after 72 hours from exposure to intensive phototherapy to evaluate its effect on the immune system.Patients and methods: A prospective cohort study carried out in Zagazig University Hospital, Pediatric Neonatal Intensive Care Unit (NICU) and Clinical Pathology Departments. The study included 50 full-term newborns. Results: There was no significant difference regarding CD4, CD8 and CD19 for the patient group. Furthermore, the study showed that the percentages of CD4+ and CD8+ lymphocytes subsets showed no change in newborns after 72 hours of exposure to phototherapy, but CD19+ was highly significantly lower before treatment only. In addition, the follow up of those 25 jaundiced newborns for occurrence and frequency of infection and need for hospitalization for a period of six months after discharge showed no effect.Conclusion: our results showed no effect of phototherapy on lymphocyte subsets after 72 hours of exposure and no effect on infant immunity

Serological and molecular survey of Leishmania parasites in apparently healthy dogs in the West Bank, Palestine

Background: Canine visceral leishmaniasis (CVL) is caused by Leishmania infantum in all Mediterranean countries. The Leishmania parasite is transmitted by the bite of a corresponding sand fly vector and primarily maintained in nature by wild and domestic reservoirs, including dogs, foxes and jackals. Infected dogs are the primary reservoir host in endemic regions and are the most significant risk disposing humans to infection. The present study aimed at assessing the prevalence of infection with Leishmania and identification of Leishmania infantum in domestic dogs in the West Bank, Palestine. Methods: The infection rate among domestic dogs collected from seven districts in the Palestinian West Bank was investigated by examination of parasites in culture from the buffy coat using serological and molecular methods; based on ELISA, internal transcribed spacer 1 (ITS1) and cysteine protease (CPB) PCR. Results: Out of 215 dogs examined for Leishmania, 36 (16.7%) were positive in at least one method. Twenty three animals (11.5%) were positive for Leishmania DNA, whereas, ELISA and culture revealed 16 (7.5%), and 4 (1.5%) respectively. CPB-PCR on one of three culture-positive isolates revealed Leishmania infantum as the causative agent for Leishmania infection in dogs. Conclusions: Our study showed that canine leishmania infection is prevalent with varying degrees in all the seven studied districts in Palestine despite the absence of human VL cases in 4 of these districts. The causative agent was confirmed to be Leishmania infantum.The authors would like to thank the Palestinian Ministry of Health (PMOH) for providing support in samples collection. Financial support is provided by the MIDDLE EAST REGIONAL COOPERATION PROGRAM (MERC) project M27- 072, on surveillance and control of visceral leishmaniasis in the Middle East & North Africa

The Association between Zinc and Copper and Cardiometabolic Risk Factors in Adults

Cardiometabolic risk (CMR) factors increase the likelihood of developing cardiovascular diseases (CVD). In Qatar, 24% of the total deaths are attributed to CVDs. Several nutritional disturbances have been linked to high risk of CVD. Many studies have discussed the effects of zinc (Zn) and copper (Cu) on CMR factors; however, evidence has been controversial. This investigated the association between CMR factors and the status of Zn, Cu, and Zn/Cu ratio. A total of 575 Qatari adults (?18 years) were obtained from Qatar Biobank. Plasma levels of Zn and Cu were determined using inductively coupled plasma mass spectrometry (ICP-MS). Anthropometric data and CMR factors were determined using standard methods. Adjusted associations between minerals and CMR were estimated by logistic regression. The associations' strength was tested using partial correlation. Zn was not strongly correlated (p-value?0.01) or significantly associated with CMR factors and metabolic syndrome (MetS). Cu levels correlated positively with body mass index (BMI) (0.23; p?0.001), pulse rate (PR) (0.18; p?0.001), total cholesterol (0.13; p=0.01), and high-density lipoproteins (HDL) (0.27; p?0.001); and negatively with diastolic blood pressure (DBP) (?0.13; p=0.01). High Cu significantly decreased the risk of MetS (0.121; p?0.001). Furthermore, Zn/Cu ratio positively correlated with waist circumference (0.13; p=0.01), systolic blood pressure (0.13; p?0.01), and DBP (0.14; p?0.01); and negatively with BMI (?0.19; p?0.001), PR (?0.17; p?0.001), and HDL (?0.27; p?0.001). High Zn/Cu ratio increased the prevalence of low HDL (4.508; p?0.001) and MetS (5.570; p?0.01). These findings suggest that high Cu levels are associated with a protective effect on DBP, HDL, and MetS and that high plasma Zn/Cu ratio is associated with the risk of low HDL and MetS. We recommend future studies to focus on minerals status among abdominally obese and prediabetic subjects because of the probable link between low serum Zn and Cu and insulin resistance and CVD

Effect of pulmonary rehabilitation programme including either O2 inhalation or noninvasive ventilation in patients with chronic obstructive pulmonary disease

Background: Pulmonary rehabilitation (PR) is crucial in managing chronic obstructive pulmonary disease (COPD) and enhancing functional capacity and health status. Oxygen therapy and noninvasive ventilation (NIV) may be needed to be incorporated into rehabilitation to augment the effectiveness of physical training. Objectives: To compare and assess the impact of the PR programme alone and with augmentation with O2 or NIV on COPD patients. Methods: Seventy-five COPD patients were equally divided into three groups: group 1 patients performed 8 week-PR programme only. Group 2 performed the PR programme while receiving O2. Group 3 completed the PR programme plus NIV. Modified Borg scale, VO2 max, modified Medical Research Council Dyspnea Scale, 6-minute walk test, COPD assessment test score, spirometric measures and arterial blood gases were assessed before and after the programme. Results: The outcome measurements showed meaningful improvement compared with the baseline in the three studied groups. However, VO2 max in group 3 showed higher significant improvement than both groups 1 and 2. Regarding 6-minute walk test, groups 2 and 3 had a higher significant improvement than group 1. COPD assessment test score in group 3 showed higher significant improvement than groups 1 and 2. Arterial blood gases in groups 2 and 3 showed significant increase in partial pressure of arterial oxygen and arterial oxygen saturation, but group 3 only had a significant decrease in PaCO2. Conclusion: O2 supplementation and NIV help severe to very severe COPD patients to perform higher exercise intensity, so they augment the benefits of PR
