Degradation of acid red 17 dye with ammonium persulphate in acidic solution using photoelectrocatalytic methods

Advanced oxidation processes (AOPs) have proved very effective in the treatment of the various hazardous organic pollutants in water. The photoelectrocatalytic degradation of azo dye acid red 17 (AR-17) with ammonium persulphate (APS) was studied. Various operational parameters effect on the photoelectrocatalytic degradation rate, such as pH and the amount of APS oxidant, were investigated. The rate of degradation of dye with these composites followed pseudo-first order kinetics in the dye concentration. The results were observed and it was found that the dye decolorization was enhanced using pH 2.0. Also, the degradation rates were found to be strongly influenced by the increasing of the APS oxidant. The addition of (NH4)2S2O8 considerably increased the removal effectiveness due to the generation SO4·− radicals

Incidence of Guillain-Barré Syndrome post COVID-19: a systematic review of case reports and case series

OBJECTIVE: The purpose of this systematic review was to study the incidence, risk factors and patients subjected to Guillain-Barré syndrome (GBS) after COVID-19. MATERIALS AND METHODS: For qualitative assessment and assessing the methodological quality, the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) checklist were utilized. Data from PubMed, Cochrane, Embase, CINAHIL, Medline, ResearchGate, and Scopus were searched. The relevant studies involved patients with confirmed COVID-19 diagnosis by RT-PCR, and GBS diagnosis based on typical clinical symptoms and/or confirmatory diagnostic results. A total of 12 English relevant articles (6 papers were case reports and 8 were case series with a total of 32 patients) published in a peer-reviewed journal from 2019 to 2021 were included. Following the review methodology, two independent raters were responsible for retrieving, extracting and checking for data eligibility. Demographic characteristics are presented as frequencies and percentages. Based on distribution of values, continuous data were expressed as median and interquartile range (IQR). RESULTS: Out of 32 patients, 26 patients reported neurological symptoms, 6 cases went unnoticed, 7 cases showed involvement of the cranial nerves, 12 cases did not, and 13 cases went unreported. CONCLUSIONS: It is too early to draw any conclusions concerning a potential relationship between SARS-CoV-2 infection and GBS. More large-scale observational studies are required to understand the pathogenesis of SARS-CoV-2-associated GBS and to demonstrate a definite causal relationship between GBS and SARS-CoV-2 infection

Evaluation of pulmonary function changes in children with type 1 diabetes mellitus in Upper Egypt

Background: Diabetes mellitus is a leading cause of morbidity and mortality among children across the world and is responsible for a growing proportion of global healthcare expenditure. However, limited data are available on lung dysfunction in children with diabetes. Aim: The aim of this study was to evaluate the pulmonary function changes in children with type 1 diabetes mellitus (T1DM). Methods: We studied 60 children with T1DM (mean age 10.5 ± 2.32 years; disease duration 2.45 ± 0.6 years, and 50 healthy control children (mean age 9.9 ± 2.5 years). Spirometry was performed for all individuals to measure forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, and peak expiratory flow rate (PEFR). Glycemic control was assessed on the basis of glycated hemoglobin (HbA1c), with HbA1c values <8% considered to indicate good glycemic control, and HbA1c values ⩾8% to indicate poor control. Results: There was significant reduction in all spirometeric parameters in diabetic children in comparison with healthy control children. Children with poor glycemic control had significant impairment in lung functions compared with those with good glycemic control. Conclusions: T1DM in children leads to impairment of lung functions and this impairment increases with poor glycemic control
