Besides its effects on physical health, the coronavirus disease 2019 (COVID-19) pandemic has resulted in adverse consequences on mental health of health-care workers. Several factors such as safety concerns and fear of infecting self or family members, social isolation measures, strict infection control procedures, lack of protective measures, exhaustion due to increased duration of working, and seeing patients die or colleagues infected can contribute to the development of mental health problems in health-care workers during the current COVID-19 pandemic. Some health-care staff including nurses, advanced practice providers, frontline health-care workers, and health-care workers who have children are more vulnerable to these mental health problems. Prevention of infection and staff burnout in health-care workers, provision of a timely mental health care, and social support are among the most important measures to provide a mental health care for health-care workers during the current COVID-19 pandemic.

Invited Review introduCtion Origin and nomenclatureThere has been a considerable controversy regarding the origin of water pipe smoking. While some believe its origin can be traced back to ancient India when it was invented by a physician Hakim Abul Fath during the reign of Emperor Akbar as a less harmful method of tobacco use, others suggest that it was first used in South Africa, Persia, Ethiopia, and other countries. The latter belief was supported by the fact that more ancient traces of water pipe smokes were found in Southern or Eastern Africa. [1][2][3] Regardless of its origin, trade routes seem to have helped disseminate the practice throughout parts of Asia and the Middle East. [4] Water pipe smoking has been recognized in different countries by different names. [5] Many of these names are of Indian, Turkish, Uzbek, Persian, or Arab origin. "Narghile" (a name commonly used in Turkey, Lebanon, Syria, Greece, and Palestine) is derived from the Persian word nārgil or "coconut." "Shisha" is from the Persian word shishe or "glass." "Hashishe" is also an Arabic word for grass, which may have been another way of saying tobacco. Hookah is an Arabic name, meaning a small box, pot, or jar. Both names refer to the original methods of constructing the smoke/ water chamber part of the hookah. "Shisha" is the name that is more commonly used in Egypt. In Iran, it is called ghalyoun or ghalyan and in Pakistan it is referred to as huqqa. [5]
