Video gaming among secondary school students in Abha, Saudi Arabia, is relatively high. Some risky behaviors such as smoking, violence, significant RTA, and violation of traffic rules were significantly associated with race and drift games and gaming in cybercafes. School-based educational programs for both adolescents and their parents should be provided to gain skills about effective time management, avoid over-gaming, risky games and gaming in cybercafes. Legal restriction on importing and selling risky video games should be considered by the government.

Micro-carriers are the best known vehicles to transport different kinds of drugs to achieve high impact. In this study, mesoporous magnesium oxide has been harnessed as a micro-carrier to encapsulate the anticancer candidate drug natural-based cubic hydroxyapatite (HAP). HAP@MgO composites with different HAP loading (0–60 wt %), were prepared by a hydrothermal treatment method using triethanol amine as a template. The characterization of the prepared composites were achieved by using XRD, Raman spectroscopy, FTIR and SEM. Characterization data confirm the formation of sphere-like structures of MgO containing HAP particles. It was observed that the size of the spheres increased with HAP loading up to 40 wt %, then collapsed. Furthermore, the anticancer property of the prepared composites was evaluated against the HepG2 liver cancer cell line. The HAP@MgO composites exhibited higher activity than neat MgO or HAP. The 20 wt % of HAP was the optimum loading to control cell proliferation by inducing apoptosis. Apoptosis was determined by typical apoptotic bodies produced by the cell membrane.

There is a significant increase noted in the incidence and prevalence of Type 2 diabetes mellitus (T2DM). The global number of diabetic patients is projected by the International Diabetes Federation (IDF) to reach 552 million. T2DM disease has chronic and progressive nature. More than fifty percent of patients do not attain adequate glycemic control despite initial sufficient monotherapy. To maintain target glycated hemoglobin (HbA1c) levels (<7%), dose adjustment and adoption of several diabetes therapies become necessary in many cases. Compared to monotherapy, a fixed drug combination of oral agents and metformin has proven to be more efficacious to maintain levels of blood glucose and HbA1c. The combination of dipeptidyl peptidase-4 inhibitors (DDPIs) and metformin has been explicated to effectively decrease HbA1c to a relatively higher degree compared to the use of either agent individually. This combination addresses various pathophysiological processes involved in T2DM pathogenesis. Additionally, the concerned combination is safe and associated with a lower risk of hypoglycemia. Moreover, it is well-tolerated and prescribed as an easy-to-use single pill to improve patient compliance. This review provides an overview of the pharmacology, efficacy, and safety of fixed drug combinations of DDPIs and metformin according to current practice.
