Background: Luteolin is a flavonoid compound that has been widely studied for its various anti-cancer properties and sensitization to multidrug-resistant cells. However, the limited solubility and bioavailability of Lut hindered its potential clinical use. Theoretically, the combination of this compound with vitamin E TPGS and poloxamer 407 can produce a synergistic effect to enhance tumor apoptosis and P-glycoprotein inhibition. This study aimed to develop and optimize vitamin E TPGS/Poloxamer 407 micelles loaded with luteolin through investigating certain factors that can affect the encapsulation efficiency and particle size of the micelle. Methods: A micelle was prepared using the film hydration method, and the micellar solution was lyophilized. The cake formed was analyzed. The factors investigated include the concentrations of the surfactants, ratio of vitamin E TPGS/Poloxamer 407, temperature of the hydrating solution, duration of hydration, and freezing temperature before lyophilization. The effects of these factors on the encapsulation efficiency and particle size of the micelle were also studied. The encapsulation efficiency was measured using a UV-Vis spectrophotometer, while particle size was measured using dynamic light scattering. Results: The optimized micelle was found to have 90% encapsulation efficiency with a particle size of less than 40 nm, which was achieved using a 10% concentration of surfactants at a vitamin E TPGS/Poloxamer 407 ratio of 3:1. The optimized temperature for hydrating the micellar film was 40 °C, the optimized mixing time was 1 h, and the optimized freezing temperature was −80 °C. The solubility of the luteolin-loaded micelles increased 459-fold compared to pure Lut in water. The critical micelle concentration of the vitamin E TPGS/Poloxamer 407 micelle was 0.001 mg/mL, and the release study showed that luteolin-loaded micelles exhibited sustained release behavior. The release of luteolin from a micelle was found to be higher in pH 6.8 compared to pH 7.4, which signified that luteolin could be accumulated more in a tumor microenvironment compared to blood. Conclusion: This study demonstrated that several factors need to be considered when developing such nanoparticles in order to obtain a well-optimized micelle.

With approximately 18 million people affected by cancer in 2020 globally, scientists are exploring innovative approaches to develop effective treatments for various types of cancer. Traditional chemotherapy drugs, although effective against cancer cells, often lead to significant side effects on healthy tissues, such as hair loss, anemia, and nausea. To discover safer alternatives, researchers are investigating natural bioactive compounds found abundantly in plants. Luteolin, a flavonoid found in celery and artichokes, stands out due to its diverse anti-carcinogenic properties, including inhibiting proliferation, inducing apoptosis, activating autophagy, and inhibiting angiogenesis and metastasis. However, the therapeutic potential of luteolin is hindered by challenges related to its bioavailability and solubility. This critical review explores the specific anti-carcinogenic properties of luteolin while analyzing the impact of its limited bioavailability and solubility on effectiveness. Additionally, it investigates the outcomes of encapsulating luteolin in nanoformulations, providing insights into potential strategies for enhancing its anti-carcinogenic effects. Finally, the review compares the efficacy of luteolin with and without nanoformulations. This review provides valuable insights into the potential of utilizing luteolin-loaded nanoformulations as a safer and more effective method for treating cancer, contributing to the ongoing efforts in improving cancer care and outcomes worldwide.

The global depression burden has remained a challenge throughout the pre- and post-pandemic era. The pandemic effect has led to the spiraling of mental disorders among young people who will be the next generation of leaders. This study aims to identify university students’ sociodemographic, psychosocial and academic backgrounds and performance associated with depression symptoms for the development of primary and secondary preventive strategies for mental health. A cross-sectional study was conducted using an online questionnaire distributed to 19 institutions in Malaysia offering a Bachelor of Pharmacy degree program. The self-rated Depression Anxiety Stress Scale (DASS-42) was used to assess depression symptoms. Pearson’s chi-square test and Fisher’s exact test were used to assess the investigated variables with depression symptoms. Independent T-test and one-way ANOVA were used to compare means of depression score across variables. Binary logistic regression was employed to examine the relationship between the investigated variables and depression symptoms. A total of 610 pharmacy students participated, of which 47% (n = 289/610) were having depression symptoms. Students who smoke nicotine and those who have separated parents, family history of mental illness, and poor academic performance were associated with depression symptoms (p < 0.05). Differences in geographical areas, race and religion also showed significant associations with depression symptoms. Parental marital status, poor academic performance, history of mental illness and comorbidities were statistically predicting depression symptoms (p < 0.05). Primary preventive strategies allowing students to harness healthy coping skills for stress, nicotine-free campaigns and a holistic curriculum are warranted. Secondary measures on mindfulness and compassion skills activities to benefit students who experienced early life crises are highly recommended. Enforcing these targeted strategies in collaboration with health and social sectors should be the primary agenda of universities to ensure their uptake.

Objective: The pharmaceutical industry has been portrayed as a promising sector for pharmacy graduates. Nonetheless, little is known about pharmacy students’ preferences, knowledge, and attitudes toward careers in the pharmaceutical industry, as well as the factors that may influence them. Method: A self-developed questionnaire was administered to pharmacy students in public and private universities in Malaysia from October to November 2018 via online platforms. Results: Only 38.8% out of 433 students who completed the survey stated their preference for working in the pharmaceutical industry. The mean (SD) of knowledge, perceived syllabus, and attitudes related to pharmaceutical industry career preferences were 8.73 (1.77) (full score of 12), 28.50 (5.83) (full score of 40), and 30.59 (4.32) (full score of 50), respectively. Students from private universities, those in years one and three of study, and those with higher attitude scores were more likely to choose the pharmaceutical industry as their career option. Conclusion: Increasing exposure to pharmaceutical industry careers that involve patient contact and clinical knowledge application is needed to improve students’ attitudes toward pursuing a career in this field.

The majority of conventional evaluations of cognitive skills (CSs) utilise paper-based or online multiple-choice questions or single best-answer questions. However, examination that uses online simulation of real scenarios has the potential to complement medium-to-high level CSs that make use of the intellectual capabilities of applying, analysing and evaluating complex information. Nevertheless, the reliability of online simulation as an alternative learning and assessment tool for Malaysian pharmacy courses has never been investigated. This paper illustrates online remote simulation-based assessment, its psychometric properties and students’ feedback towards this new learning and assessment tool opportunity. A virtual web-based simulation examination consisting of three infectious disease scenarios was administered in an undergraduate pharmacy course to assess physically distanced students for medium-level clinical pharmacy CSs. Students responded through written typed communication to online enquiries from health professionals, patients or caretakers’ avatars. Rasch analysis and a feedback survey were employed to measure the reliability of online simulation and to understand students’ experiences with the new web-based tool. This study found that the remote simulation examination had good reliability (ir = 0.95, pr = 0.73) for measuring medium-level clinical pharmacy CSs. The students’ survey indicates that the web-based simulation activities improved knowledge, engagement and cognitive reasoning. This article contributes to the pharmacy education literature by illustrating how a different type of assessment is feasible and reliable for evaluating students’ CSs for final examinations and potentially has equitable opportunities for distance-learning students to enhance their learning capabilities and show their performances. Future research to investigate the potential of remote online simulation examinations for inter-professional learning and assessment is highly recommended.
