Background: Sexually transmitted diseases (STDs) remain one of the most important health challenges in not only developing countries but also developed countries. Discussing STDs in the Saudi society is considered taboo, as social factors and ethics give rise to many obstacles. This study evaluates the knowledge of STDs among young adult students enrolled in Albaha University. Methods: This research is a cross-sectional study involving 1902 young adult students registered at Albaha University. STDs knowledge scores (STDs-KSs) were calculated using a predesigned and validated STDs knowledge questionnaire with 27 items adapted from previously developed questionnaires. Results: The estimated overall mean of STDs-KS was 7.95 ± 4.29. Female participants showed a significantly higher mean of STDs-KS, compared to males (8.51 ± 4.14 vs. 7.32 ± 4.38, p < 0.0001). Participants registered in health sciences programs showed higher STDs-KS, compared to participants from arts and sciences programs (p < 0.0001). Conclusions: Evidence from this study suggests a lack of STDs knowledge among young adults. To promote STDs awareness among this population, more health educational programs should be included in school curricula at the late stages of secondary education.

Tuberculosis (TB), one of the deadliest contagious diseases, is a major concern worldwide. Long-term treatment, a high pill burden, limited compliance, and strict administration schedules are all variables that contribute to the development of MDR and XDR tuberculosis patients. The rise of multidrug-resistant strains and a scarcity of anti-TB medications pose a threat to TB control in the future. As a result, a strong and effective system is required to overcome technological limitations and improve the efficacy of therapeutic medications, which is still a huge problem for pharmacological technology. Nanotechnology offers an interesting opportunity for accurate identification of mycobacterial strains and improved medication treatment possibilities for tuberculosis. Nano medicine in tuberculosis is an emerging research field that provides the possibility of efficient medication delivery using nanoparticles and a decrease in drug dosages and adverse effects to boost patient compliance with therapy and recovery. Due to their fascinating characteristics, this strategy is useful in overcoming the abnormalities associated with traditional therapy and leads to some optimization of the therapeutic impact. It also decreases the dosing frequency and eliminates the problem of low compliance. To develop modern diagnosis techniques, upgraded treatment, and possible prevention of tuberculosis, the nanoparticle-based tests have demonstrated considerable advances. The literature search was conducted using Scopus, PubMed, Google Scholar, and Elsevier databases only. This article examines the possibility of employing nanotechnology for TB diagnosis, nanotechnology-based medicine delivery systems, and prevention for the successful elimination of TB illnesses.
