We adhere to conventional design principles for all our sequential eBook publications to circumvent the trend of "hypercoloremia mania" in eBook design. This predominantly employs the official black and white colour scheme. This publication resulted from a collaborative effort with my skilled and dedicated coauthors, namely PharmDs Dana AlTaweel, Najd Alyasjeen, Leen Albishawi, Farah Qaryouti, Arwa Alashqar, Kariman Hatem, Eman Awwad, Alia' Saidan, Areej Al-Manasyeh, Marah Hussein, and. Duaa Alqhaiwi.
