Long-term Cardiovascular Adverse Events Induced by Fluoroquinolones: A Retrospective Case-control Study.

ABSTRACT: A correlation is already established between fluoroquinolones (FQs) use and cardiovascular events (CVEs), such as QT prolongation; however, serious events such as aortic aneurysm and valve regurgitation have also been reported with FQs. Several unstudied factors could contribute to the development of different CVEs that were not previously evaluated with FQ therapy. Therefore, we aimed to assess the incidence of different serious CVEs after completion of FQ therapy and potential associating factors. This was a retrospective case-control study of inpatients who received ciprofloxacin, levofloxacin, or moxifloxacin for ≥3 days. Patients' echocardiograms were evaluated for the development of aortic or valvular disease or worsening of an existing condition after completion of therapy. Of 373 included patients, 83 developed new valvular disease or worsening of an existing disease, where tricuspid valve regurgitation was the most common CVE (50/83; 60.2%), followed by mitral valve diseases (48/83; 57.8%). Aortic valve regurgitation occurred more commonly with moxifloxacin compared with ciprofloxacin and levofloxacin (17.8% vs. 6.7% and 10.7%, respectively; P = 0.01). Median time to CVE detection ranged 93-166 days for all FQs. The receipt of moxifloxacin and elevated baseline QT interval were associated with an increased CVEs risk (adjusted odds ratio 3.26; 95% confidence interval, 1.31-8.11 and adjusted odds ratio 1.02; 95% confidence interval, 1.00-1.04, respectively). Other factors did not show such association. The lack of association of different factors with the occurrence of CVEs indicates that all patients receiving FQ therapy, especially moxifloxacin, should be monitored during the first-year after therapy. Alternatively, other antibiotics with a better safety profile may be considered.

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.
