BACKGROUND: Patients boarded in the emergency department (ED) with psychiatric complaints may be at risk for medication errors. However, no studies exist to characterize the types of errors and risk factors for errors in these patients. OBJECTIVE: To characterize medication errors in psychiatric patients boarded in ED, and to identify risk factors associated with these errors. METHODS: A prospective observational study conducted in a community ED included all patients seen in the ED for primary psychiatric complaints and remained in the ED pending transfer to a psychiatric facility. An investigator recorded all medication errors requiring an intervention by an emergency pharmacist. RESULTS: A total of 288 medication errors in 100 patients were observed. Overall, 65 patients had one or more medication errors. The majority of errors (n = 256, 89%) were due to errors of omission. The final severity classification of the medication errors was: Insignificant (n = 77), significant (n = 152), and serious (n = 3). In the multivariate analysis (R-squared 19.6%), increasing number of home medications (OR 1.17, 95% CI 1.01 to 1.36; p = 0.035), and increasing number of comorbidities (OR 1.89, 95% CI 1.10 to 3.27; p = 0.022) were associated with the occurrence of medication errors. CONCLUSION: Psychiatric patients boarded in the ED commonly have medication errors that require intervention.

Scabies is an invasive skin condition caused by Sarcoptes scabiei mites. The present study investigates the antiscabies potential of coconut seed extract (CSE) in rabbits. GC-MS analysis of the seed oil identified 17 known compounds, while CSE phytochemical investigation afforded 4 known ones. The topical application of seed extract improved all signs of infection, and the improvement started 3 days post application. However, in vitro application of the extract caused 99% mortality of mites 1 day post application. Histopathological examination revealed the absence of inflammatory infiltration and hyperkeratosis of the epidermis, compared with ivermectin-treated groups which revealed less improvement. The mRNA gene expression results revealed a suppression of IL-1β, IL-6, IL-10, MMP-9, VEGF, and MCP-1, and an upregulation of I-CAM-1, KGF as well as TIMP-1. The docking analysis emphasized a strong binding of gondoic acid with IL-1β, IL-6, and VEGF with high binding scores of −5.817, −5.291, and −8.362 kcal/mol, respectively, and a high binding affinity of 3″(1‴-O-β-D-glucopyranosyl)-sucrose with GST with −7.24 kcal/mol. Accordingly, and for the first time, our results highlighted the scabicidal potential of coconut seed extract, which opens the gate for an efficient, cost-effective as well as herbal-based alternative for the control of scabies in rabbits.

Pakistan has more than 18,000 brick kilns and produced about 45 billion bricks every year. Brick making in Pakistan is a traditional small-scale and unmanaged industry. Coal is a major source of fuel for brick kilns. In Pakistan, urbanization, in terms of building construction has increased by 10% per year from 2015 to 2020. That growth has increased demand of building construction stock by 80% which causes an increased production of building materials and bricks. This increase in demand for bricks will increase the consumption of coal used in brick manufacturing. Therefore, there is an urgent need to assess the health risk to people living near brick kilns. This study assesses the health risk due to the emission of air pollutants from brick kilns. Two non-carcinogenic pollutants (i.e., SO 2 and Hg) and three carcinogenic pollutants (i.e., As, Cd and Cr) were selected for this health risk assessment. Both short-term and long-term health impacts were assessed. The AERMOD air dispersion model was used for predicting ground-level concentrations within a 10 km radius of the brick kilns. Non-carcinogenic health risk assessments indicate adverse health impacts from short-term concentrations, while long-term concentrations are within acceptable limits. Carcinogenic health risks also indicate adverse health effects from short-term concentration, while only As and Cr cause adverse health impacts from long-term concentration and exposure. The findings of this study show that a detailed assessment of the health effects caused by emissions from all of the brick kilns and ambient air concentration with meteorological conditions should be carried out.

Background In case of emergencies, the number and severity of mass casualties may exceed medical services resources. Saudi Arabia is prone to different disasters, and all medical resources should be ready and prepared to serve during disasters. Pharmacists are essential during disasters; however, their roles have not been well studied during disasters in Saudi Arabia. Methods An observational cross-sectional study targeted tertiary hospitals in Jeddah. An electronic survey, consisting of 34 questions, was developed and distributed to pharmacy directors or their representatives to investigate the hospital pharmacies’ preparedness and pharmacist roles during disasters in the city of Jeddah. Results Six hospitals participated in the survey, with a 100% response rate. All respondents confirmed the presence of disaster plans involving pharmacy departments. Hospital committee consensuses determined which medication to stock in five hospitals (83.3%). All six respondents (100%) agreed that the following medication supplies were adequate in the event of disasters: analgesics, rapid sequence intubation medications (ie, sedatives and paralytics), respiratory medications, antimicrobials, and maintenance intravenous (IV) fluids. There was disagreement on the adequacy of wound infection prophylaxis, vasopressors/inotropes, antiemetic medications, ophthalmic medications, and antidotes for chemical weapons. There were discrepancies on pharmacist roles during disaster, but hospitals agreed on the following roles: maintain effective distribution and control, collaborate on medication management, and develop and maintain first-aid skills. Conclusion All included facilities have emergency preparedness plans for the hospitals and the pharmacy departments. However, the type and quantities of stocked medications, as well as pharmacist roles, are not well recognized. The results highlight the need for national guidance to enhance and support the preparedness of healthcare facilities.

Background Ulcerative colitis (UC) is an inflammatory bowel disease. Fucoidan, sulfated polysaccharide of brown seaweed, demonstrates various pharmacological actions as anti-inflammatory, anti-tumor and anti-bacterial effects. Therefore, we opt to investigate the potential curative effects of fucoidan in experimentally induced UC in rats through modulating aryl hydrocarbon receptor (AhR), phosphodiesterase-4 (PDE4), nuclear factor erythroid 2-related factor 2 (Nrf2) and Heme Oxygenase-1 (HO-1). Methods UC was induced in rats using intracolonic 2 ml of 4% acetic acid. Some rats were treated with 150 mg/kg fucoidan. Samples of colon were used to investigate gene and protein expression of AhR, PDE4, Nrf2, HO-1 and cyclic adenosine monophosphate (cAMP). Sections of colon were stained with hematoxylin/eosin, Alcian blue or immune-stained with anti-PDE4 antibodies. Results Investigation of hematoxylin/eosin stained micro-images of UC rats revealed damaged intestinal glands, severe hemorrhage and inflammatory cell infiltration, while sections stained with Alcian Blue revealed damaged and almost absent intestinal glands. UC results in elevated gene and protein expression of PDE4 associated with reduced gene and protein expression of AhR, IL-22, cAMP, Nrf2 and HO-1. Finally, UC increased the oxidative stress and reduced antioxidant activity in colon tissues. All morphological changes as well as gene and protein expressions were ameliorated by fucoidan. Conclusion Fucoidan could treat UC induced in rats. It restored the normal weight and length of colon associated with morphological improvement as found by examining sections stained with hematoxylin/eosin and Alcian Blue. The curative effects could be explained by enhancing antioxidant activity, reducing the expression of PDE4 and increasing the expression of AhR, IL-22 and cAMP.

Pluchea indica (L.) Less. (Asteraceae) commonly known as Indian camphorweed, pluchea, or marsh fleabane has gained great importance in various traditional medicines for its nutritional and medicinal benefits. It is utilized to cure several illnesses such as lumbago, kidney stones, leucorrhea, inflammation, gangrenous and atonic ulcer, hemorrhoids, dysentery, eye diseases, itchy skin, acid stomach, dysuria, abdominal pain, scabies, fever, sore muscles, dysentery, diabetes, rheumatism, etc. The plant or its leaves in the form of tea are commonly used for treating diabetes and rheumatism. The plant is a rich source of calcium, vitamin C, dietary fiber, and β-carotene. Various biomolecules have been isolated from P. indica, including thiophenes, terpenes, quinic acids, sterols, lignans, phenolics, and flavonoids. The current review reports detailed information about the phytoconstituents and pharmacological relevance of P. indica and the link to its traditional uses. The reported studies validated the efficacy and safety of P. indica, as well as supported its traditional uses for treating various ailments and promoting health and well-being. Thus, this could encourage the development of this plant into a healthy food supplement or medicine for the prevention and treatment of various diseases. However, further studies on the drug interactions, mechanism of action, pharmacokinetics, toxicology, and metabolism, as well as clinical trials, should be carried out.

Patients with ulcerative colitis (UC) experience diarrhoea, hematochezia and abdominal pain. UC is a well-known health challenge affecting 200-250 per 100 000 individuals worldwide, with a similar prevalence in both sexes and elevated upon activation of gut immune responses. We evaluated the potential therapeutic effects of cycloastragenol in experimentally induced UC rats and examined the modulation of sphingosine kinase (SphK), macrophage inflammatory protein (MIP)-1α and miR-143. We treated UC rats with 30 mg/kg cycloastragenol and assessed gene and protein expression levels of SphK, MIP-1α, B-cell lymphoma 2 (BCL2), BCL2-associated X (BAX), miR-143, NF-κB, tumour necrosis factor (TNF)-α and active caspase-3. Colon sections were examined using electron microscopy; additional sections were stained with haematoxylin-eosin or immunostained with anti-TNF-α and anti-caspase-3 antibodies. Electron microscopy of UC specimens revealed dark distorted goblet cell nuclei with disarranged mucus granules and a nondistinct brush border with atypical microvilli. Haematoxylin-eosin staining showed damaged intestinal glands, severe haemorrhage and inflammatory cell infiltration. Cycloastragenol treatment improved the induced morphological changes. In UC rats, cycloastragenol significantly reduced expression levels of SphK, MIP-1α, BAX, NF-κB, TNF-α and active caspase-3, associated with BCL2 and miR-143 overexpression. Therefore, cycloastragenol protects against UC by modulating SphK/MIP-1α/miR-143, subsequently deactivating inflammatory and apoptotic pathways.K E Y W O R D S active caspase-3, B-cell lymphoma 2 (BCL2), BCL2 associated X (BAX), macrophage inflammatory protein (MIP)-1α, miR-143, nuclear factor (NF)κB, sphingosine kinase (SphK), tumour necrosis factor (TNF)-α

Cancer represents one of the most prevalent causes of global death. CK2 (casein kinase 2) activation boosted cancer proliferation and progression. Therefore, CK2 inhibition can have a crucial role in prohibiting cancer progression and enhancing apoptosis. Fungi have gained vast interest as a wealthy pool of anticancer metabolites that could particularly target various cancer progression-linked signaling pathways. Phenalenones are a unique class of secondary metabolites that possess diverse bioactivities. In the current work, the CK2 inhibitory capacity of 33 fungal phenalenones was explored using computational studies. After evaluating the usefulness of the compounds as enzyme inhibitors by ADMET prediction, the compounds were prepared for molecular docking in the CK2-α1 crystal structure (PDB: 7BU4). Molecular dynamic simulation was performed on the top two scoring compounds to evaluate their binding affinity and protein stability through a simulated physiological environment. Compound 19 had a superior binding affinity to the co-crystallized ligand (Y49). The improved affinity can be attributed to the fact that the aliphatic chain makes additional contact with Asp120 in a pocket distant from the active site.
