Background. According to the WHO, glaucoma is the second leading cause of blindness worldwide. About 50% of the world’s glaucoma cases come from the Asian population, and in Malaysia itself, the prevalence of glaucoma is increasing. However, glaucoma is still a foreign word to our community despite the high prevalence. Therefore, there is an urgent need to determine the awareness of glaucoma among the community and its associated factors. Results. This study showed that only 25.2% of our respondents were aware of glaucoma and it is associated with ethnicity, religion, education, and household income. Besides, among those who were aware, they fall into the group of poor knowledge of glaucoma. On the other hand, the knowledge of glaucoma was associated with occupation and the awareness of glaucoma by definition. The validated questionnaire was distributed and the data were analyzed by SPSS software using t-test, one-way ANOVA, and chi-square test. Conclusion. Awareness and knowledge of glaucoma in this population is low. These findings suggest that there is a need for an efficient information and education strategy to be designed and conducted to increase the awareness and knowledge of glaucoma so that early detection can be made and effective management of individuals with this condition can be delivered.

The present study aimed to develop polyethylene glycol–liquid crystals (PEG-LC) ointment formulations, assess their formulation characteristics, and establish their biocompatibility and impact on transdermal drug administration. PEG-LC formulations were prepared using a hydrophilic molecule, p-aminobenzoic acid (PAB). Formulation characterizations such as small-angle X-ray scattering, viscosity, pH, zeta potential, and the particle sizes of the formulations were examined to determine the physicochemical properties of the prepared formulations. The drug release profile of PEG-LC ointment formulations was assessed with a dialysis membrane. In vitro skin permeation testing was performed to establish whether the PEG-LC formulations improved drug skin penetration. The MTT and comet assays were performed to assess the biocompatibility of the formulations. Our data showed that the method is effective in forming hexosome-type PEG-LC formulations and that they were biocompatible. Furthermore, the PEG-LC formulations significantly improved PAB skin penetration when compared with commercial PEG. The PEG-LC formulation is a promising carrier for the delivery of hydrophilic drugs.

Background and Aim: The development of a coronavirus disease 2019 (COVID-19) vaccine is ongoing. This study aimed to prepare for public acceptance of the vaccine. There is a need to identify the current acceptance and potential barriers to receiving a COVID-19 vaccine in Yemen. Understanding the hesitancy and acceptance of a COVID-19 vaccine are crucial to develop local evidence-based interventions. Materials and Methods: Twenty students were interviewed in this study. An interview guide was developed and it addressed the willingness to accept a future COVID-19 vaccine. In-depth interviews were conducted, transcribed, and manually analyzed. Results: The majority of participants agreed that they would take a COVID-19 vaccine for several reasons, including protection for themselves, their families, and others and to stop the spread of COVID-19, for which the vaccine is important, as in other routine vaccinations. However, some participants shared that they would not take the COVID-19 vaccine due to the following reasons: Concerns regarding the safety of the vaccine; feeling fit and healthy, and thus considering themselves to have strong immunity; feeling that the vaccine was manufactured in a rushed manner and thus it would require approval by the World Health Organization; being previously infected with COVID-19 and considering themselves protected, and placing their trust in God and believing no vaccine was needed. Conclusion: The willingness to receive a future COVID-19 vaccine was high among medical students. However, some students hesitated to take the vaccine. Therefore, mass media interventions are required to maximize vaccine uptake.
