Aspirin prescribing pattern and guidelines-adherence evaluation for primary prevention of cardiovascular diseases at a teaching hospital.

The present study investigates the aspirin prescribing pattern and guidelines-adherence evaluation for primary prevention of cardiovascular diseases at a teaching hospital. A total of 816 patients were included in the study, the patients who received aspirin aged 60-69 (29.65%), followed by patients aged 50-59 years old (29.53%) and 70-79 years old (22.91%). Demographic information shown that the majority of the patients were males (58.55%). The BMI revealed that 85.78% of patients were obese. The majority of the patients have diabetes 78.67%, hypertension 74.38%, and dyslipidemia 65.68%. The mean systolic blood pressure was 136 ± 7.4 and diastolic blood pressure was 74.9 ± 5.2. After applying aspirin candidacy calculation, only 6% patients were highly recommended to be on aspirin, 49% patients had reasonable recommendation of aspirin, 27% patients use aspirin based on "may be considered" recommendation, and 23% patients were on aspirin with no indication or recommendation. The study highlights the importance of following the international recommendations in aspirin prescribing, and flags the inappropriate use and prescribing by our healthcare providers. The current study encourages further investigation to be carried out which should include patient and clinician education, to well understand and alleviate the inequalities in aspirin use and adherence. Further studies are also warranted to understand of the prescribing pattern and to provide solutions to avoid aspirin associated complications.

Production of a biopesticide on host and Non-Host serine protease inhibitors for red palm weevil in palm trees.

Serine proteases are essential metabolic enzymes in the midgut of many pests, including the red palm weevil (RPW), Rhynchophorus ferrugineus Olivier, which has a significant impact economically, environmentally and socially worldwide especially in the middle east. Some methods have been used to manage this pest such as trapping of RPW with pheromones, chemicals, and X-rays. However, these methods are costly, not effective and negatively impact the human. The main objective of this study is to contribute to the discovery of an eco-friendly pesticide to eradicate this infection by using serine protease inhibitors (SPIs) extracted from different parts of plant resources. In this research, both in vitro and in vivo effects of SPIs activity against RPW were examined. The protease inhibitors (PIs) activity was recorded in the crude extract that was isolated from the date's kernel (DKE), host and Calotropis latex (CLE), non-host. These PIs were partially purified by ammonium sulfate precipitation. The midgut tissue of RPW was extracted and analyzed for protases activity assay. PIs assays were consistent with the increased in the inhibitory activity against the midgut proteases after treatment with a DKE and CLE. The reduction of gut proteases by DKE solution and CLE was 39%, 18%, respectively. Partially purified DKE showed the most prominent inhibition pattern of protease activity of the gut extract. While, latex exhibited acute toxicity, imparting the least LC50 (5.132 mg/mL) against RPW larvae. Taken together, these findings provide evidence for the hypothesis that SPIs activity may play an important role in enhancing the mortality of RPW and relieving the toxicity of insecticide in palm trees.
