ANTIPSYCHOTICS- CLASSIFICATION, USES, AND ADVERSE EFFECTS

Introduction: Antipsychotic agents are categorized usually as either “typical antipsychotics” or “atypical antipsychotics”. Typical antipsychotic pharmacological agents, which are also called first-generation antipsychotics or traditional antipsychotics, include chlorpromazine and haloperidol. On the other hand, atypical antipsychotic pharmacological agents, which are also called second generation antipsychotics, include risperidone, quetiapine, and olanzapine. Both typical and atypical antipsychotics work in similar mechanisms by inhibiting the activation of specific receptors in the dopamine pathway.Aim of work: In this review, we will discuss the antipsychotics- classification, uses, and adverse effects, Methodology: We did a systematic search for antipsychotics- classification, uses, and adverse effects using PubMed search engine (http://www.ncbi.nlm.nih.gov/) and Google Scholar search engine (https://scholar.google.com). All relevant studies were retrieved and discussed. We only included full articles.Conclusions: The prescription of atypical antipsychotic agents, like quetiapine and olanzapine, has been significantly increasing and in many conditions, they are sometimes prescribed “off-label” – which is a worrying trend due to their possible risk of developing harmful adverse events. Therefore, atypical antipsychotic agents must only be used in their specific indications and with caution, especially among older patients and young adults. Atypical antipsychotic agents can be indicated for schizophrenia treatment and other associated conditions and in some cases to treat the behavioral and psychological manifestations related to dementia (risperidone only). Antipsychotics are not first-line treatments for patients with anxiety and are not generally recommended for the use in patients with posttraumatic stress disorder or insomnia. Key words: antipsychotics, classification, uses, and adverse effects

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Teacher\u27s Attitudes towards Integrating Technology: Case Studies in Saudi Arabia and the United States

This study examines teachers\u27 attitudes towards integrating technology in Saudi Arabia and the United States. A case study approach was used to identify several factors that challenge teachers and schools to adapt or integrate technology. And, the case study also reveals similarities and differences between the preparation and practice of teachers in Saudi Arabia and in the United States. The data was collected through semi-structured interviews distributed to ten teachers from Saudi Arabia and the United States. These interviews were analyzed to determine teachers\u27 attitudes in both countries and to compare and contrast these results. Findings reveal that teachers from both countries note positive educational benefits in using technology, but that there is also a discrepancy between how teachers are prepared to use technology and in the availability of technology in their classrooms. And unfortunately, most teachers seem to lack the time needed to learn to use and apply technology in meaningful ways into the curriculum

Synthesis and Characterization of Calcium Alginate-Based Microspheres Entrapped with TiO₂ Nanoparticles and Cinnamon Essential Oil Targeting Clinical <i>Staphylococcus aureus</i>

It is important to create new generations of materials that can destroy multidrug-resistant bacterial strains, which are a serious public health concern. This study focused on the biosynthesis of an essential oil entrapped in titanium dioxide (TiO2) calcium alginate-based microspheres. In this research, calcium alginate-based microspheres with entrapped TiO2 nanoparticles and cinnamon essential oil (CI-TiO2-MSs) were synthesized, using an aqueous extract of Nigella sativa seeds for TiO2 nanoparticle preparation, and the ionotropic gelation method for microsphere preparation. The microspheres obtained were spherical, uniformly sized, microporous, and rough surfaced, and they were fully loaded with cinnamon essential oil and TiO2 nanoparticles. The synthesized microspheres were analyzed for antibacterial activity against the clinical multidrug-resistant strain of Staphylococcus aureus. Disc diffusion and flow cytometry analysis revealed strong antibacterial activity by CI-TiO2-MSs. The synthesized CI-TiO2-MSs were characterized by the SEM/EDX, X-ray diffraction, and FTIR techniques. Results showed that the TiO2 nanoparticles were spherical and 99 to 150 nm in size, whereas the CI-TiO2-MSs were spherical and rough surfaced. Apoptosis analysis and SEM micrography revealed that the CI-TiO2-MSs had strong bactericidal activity against S. aureus. The in vitro antibacterial experiments proved that the encapsulated CI-TiO2-MSs had strong potential for use as a prolonged controlled release system against multidrug-resistant clinical S. aureus

Enhancing the Performance of a Metal-Free Self-Supported Carbon Felt-Based Supercapacitor with Facile Two-Step Electrochemical Activation

Carbon felt (CF) is an inexpensive carbon-based material that is highly conductive and features extraordinary inherent surface area. Using such a metal-free, low-cost material for energy storage applications can benefit their practical implementation; however, only limited success has been achieved using metal-free CF for supercapacitor electrodes. This work thoroughly studies a cost-effective and simple method for activating metal-free self-supported carbon felt. As-received CF samples were first chemically modified with an acidic mixture, then put through a time optimization two-step electrochemical treatment in inorganic salts. The initial oxidative exfoliation process enhances the fiber’s surface area and ultimately introduced oxygen functional groups to the surface, whereas the subsequent reduction process substantially improved the conductivity. We achieved a 205-fold enhancement of capacitance over the as-received CF, with a maximum specific capacitance of 205 Fg−1, while using a charging current density of 23 mAg−1. Additionally, we obtained a remarkable capacitance retention of 78% upon increasing the charging current from 0.4 to 1 Ag−1. Finally, the cyclic stability reached 87% capacitance retention after 2500 cycles. These results demonstrate the potential utility of electrochemically activated CF electrodes in supercapacitor devices

Alpha Lipoic Acid as a Protective Mediator for Regulating the Defensive Responses of Wheat Plants against Sodic Alkaline Stress: Physiological, Biochemical and Molecular Aspects

Recently, exogenous α-Lipoic acid (ALA) has been suggested to improve the tolerance of plants to a wide array of abiotic stresses. However, there is currently no definitive data on the role of ALA in wheat plants exposed to sodic alkaline stress. Therefore, this study was designed to evaluate the effects of foliar application by ALA at 0 (distilled water as control) and 20 µM on wheat seedlings grown under sodic alkaline stress (50 mM 1:1 NaHCO3 & Na2CO3; pH 9.7. Under sodic alkaline stress, exogenous ALA significantly (p ≤ 0.05) improved growth (shoot fresh and dry weight), chlorophyll (Chl) a, b and Chl a + b, while Chl a/b ratio was not affected. Moreover, leaf relative water content (RWC), total soluble sugars, carotenoids, total soluble phenols, ascorbic acid, K and Ca were significantly increased in the ALA-treated plants compared to the ALA-untreated plants. This improvement was concomitant with reducing the rate of lipid peroxidation (malondialdehyde, MDA) and H2O2. Superoxide dismutase (SOD) and ascorbate peroxidase (APX) demonstrated greater activity in the ALA-treated plants compared to the non-treated ones. Conversely, proline, catalase (CAT), guaiacol peroxidase (G-POX), Na and Na/K ratio were significantly decreased in the ALA-treated plants. Under sodic alkaline stress, the relative expression of photosystem II (D2 protein; PsbD) was significantly up-regulated in the ALA treatment (67% increase over the ALA-untreated plants); while Δ pyrroline-5-carboxylate synthase (P5CS), plasma membrane Na+/H+ antiporter protein of salt overly sensitive gene (SOS1) and tonoplast-localized Na+/H+ antiporter protein (NHX1) were down-regulated by 21, 37 and 53%, respectively, lower than the ALA-untreated plants. These results reveal that ALA may be involved in several possible mechanisms of alkalinity tolerance in wheat plants
