Thymoquinone Ameliorates Carfilzomib-Induced Renal Impairment by Modulating Oxidative Stress Markers, Inflammatory/Apoptotic Mediators, and Augmenting Nrf2 in Rats.

Chemotherapy-induced kidney damage is an emerging problem that restricts cancer treatment effectiveness. The proteasome inhibitor carfilzomib (CFZ) is primarily used to treat multiple myeloma and has been associated with severe renal injury in humans. CFZ-induced nephrotoxicity remains an unmet medical need, and there is an urgent need to find and develop a nephroprotective and antioxidant therapy for this condition. Thymoquinone (TQ) is a bioactive compound that has been isolated from Nigella sativa seeds. It has a wide range of pharmacological properties. Therefore, this experimental design aimed to study the effectiveness of TQ against CFZ-induced renal toxicity in rats. The first group of rats was a normal control (CNT); the second group received CFZ (4 mg/kg b.w.); the third and fourth groups received TQ (10 and 20 mg/kg b.w.) 2 h before receiving CFZ; the fifth group received only TQ (20 mg/kg b.w.). This experiment was conducted for 16 days, and at the end of the experiment, blood samples and kidney tissue were collected for biochemical assays. The results indicated that administration of CFZ significantly enhanced serum marker levels such as BUN, creatinine, and uric acid in the CFZ group. Similarly, it was also noticed that CFZ administration induced oxidative stress by reducing antioxidants (GSH) and antioxidant enzymes (CAT and SOD) and increasing lipid peroxidation. CFZ treatment also enhanced the expression of IL-1ß, IL-6, and TNF-α production. Moreover, CFZ increased caspase-3 concentrations and reduced Nrf2 expression in the CFZ-administered group. However, treatment with 10 and 20 mg/kg TQ significantly decreased serum markers and increased antioxidant enzymes. TQ treatment considerably reduced IL-1ß, IL-6, TNF-α, and caspase-3 concentrations. Overall, this biochemical estimation was also supported by histopathological outcomes. This study revealed that TQ administration significantly mitigated the negative effects of CFZ treatment on Nrf2 expression. Thus, it indicates that TQ may have utility as a potential drug to prevent CFZ-induced nephrotoxicity in the future.

Factors influencing future career interests of pharmacy interns in Saudi Arabia: a survey from 25 colleges of pharmacy.

BACKGROUND: Hundreds of pharmacists graduate from pharmacy colleges in Saudi Arabia, and various factors influence their choice of career pathway. Very few single-institution studies assessed career choices of pharmacy students with or without evaluating the influencing factors. Therefore, this study aimed to evaluate career choices and the associating factors of pharmacy interns from multiple colleges in Saudi Arabia. METHODS: This was a cross-sectional study that surveyed pharmacy interns from 25 pharmacy colleges in Saudi Arabia using an online questionnaire. The survey was sent during the last rotation month in the internship year (May-June 2022). RESULTS: Of 454 participants, 411 (90.5%) were enrolled in Doctor of Pharmacy programs. While most participants were interested in becoming clinical pharmacists (n = 183; 40.3%), a considerable number were also interested in working in different sectors of pharmaceutical companies and industry (n = 127; 28%). Internship training significantly correlated with selecting clinical pharmacy specialist career (r = 0.19; P = 0.0001), whereas salary/financial incentives significantly influenced the choice of working as sales and marketing representatives and pharmacy product specialists in pharmaceutical companies (r = 0.29 and 0.24; P < 0.0001 for both). College courses correlated with choosing academia in pharmaceutical sciences (r = 0.20; P < 0.0001), whereas summer training correlated with the community pharmacy career (r = 0.11; P = 0.02). CONCLUSION: Pharmacy colleges should utilize results from this study to enhance the exposure of pharmacy students during their academic years to different pharmacy career pathways by allowing the opportunity to shadow pharmacists from different sectors as part of college courses, inviting previous graduates, and activating the role of academic advisors in career orientation.
