RESUMEN
Background Patient safety and quality of surgical care are crucial in healthcare. Adequate knowledge and attitudes among healthcare providers regarding differentiating malpractice from surgical complications are essential for preventing adverse events. We aimed to assess medical students' knowledge and attitudes toward patient safety in surgical procedures. Methodology A cross-sectional study was conducted among clinical years of medical students and interns at Al-Baha University, Saudi Arabia, from June 15, 2023, to August 1, 2023. Exclusion criteria were students from basic years, pharmacology students, applied medical science, dental students, and students from other universities. A self-administered questionnaire collected data on participants' demographics, knowledge, attitudes, and practices related to patient safety in surgical procedures. Results A total of 271 medical students participated, exceeding the target sample size of 181. Participants' ages ranged from 20 to 28 years, with the majority between 23 and 25 (60.5%). Males accounted for 63.8% of participants. The largest group was fourth-year students (31.7%), followed by interns (23.6%), those in sixth year (23.2%), and those in fifth year (21.4%). Moreover, 82.7% of participants demonstrated good knowledge of patient safety concepts. The highest level of knowledge was noted among fourth-year students (89.5%), and the lowest was among fifth-year medical students (75.9%), but was not statistically significant (p=0.701). Most participants demonstrated appropriate attitudes and practices (83.6%); however, 9.2% refused to perform surgery on a patient with active hepatitis B due to concerns for their own safety. Conclusion The majority of participants exhibited suitable knowledge and attitudes toward patient safety in surgical scenarios, but there was deficient knowledge among fifth- and sixth-year students. Moreover, a negative attitude regarding patient safety was noticed, exemplified by refusing surgeries on patients with active hepatitis B.
RESUMEN
This study investigates the antioxidant activities of lipid, protein, and carbohydrate extracts from the marine mollusk Perna canaliculus. Lipids were extracted using acetone, which was followed by protein extraction using the broad-spectrum enzyme Alcalase and then carbohydrate extraction using cetylpyridinium chloride. Eighty white BALB/c mice were divided into eight groups according to the administered extracts. Groups 1 and 5 were the control and toxin control groups, respectively. Groups 2, 3, and 4 were administered lipid, protein, and carbohydrate extracts, respectively. The other groups were administered P. canaliculus extracts as well as gentamicin and acetaminophen, known as ethanolic extracts, derived from Nerium oleander to induce oxidation stress. All groups showed significant improvements in body weight (p < 0.05). The lipid extract group showed a significant decrease in low-density lipoprotein cholesterol (p < 0.05) and a significant increase in high-density lipoprotein cholesterol (p < 0.05). After the toxin injection, all groups treated with P. canaliculus extracts showed increased antioxidant effects on hepatocytes (p < 0.05). The lipid extracts induced antioxidant effects to protect the kidney by increasing lipid peroxidation (p < 0.05) and catalase activities (p < 0.05). Also, protein extracts showed antioxidant effects by increasing glutathione and catalase levels significantly (p < 0.005). In conclusion, P. canaliculus extracts, especially lipids and proteins, have potent antioxidant activities that protect vital organs from oxidation stress.
