Cadmium chloride (CdCl 2) as an environmental and industrial toxin has a significant detrimental effect on the testis (Nna et al., 2017). CdCl 2 is in the heavy metal group that is primarily released from colour pigments, TV screens, plating, battery manufacturing, plastics and fertilisers, and mining activities (Saini & Dhania, 2020). This combination enters the human body through contaminated food, drinking water and inhalation of air containing CdCl 2 particles or smoke containing CdCl 2 due to occupational exposure or air pollution caused by jungle fire (Rehman et al., 2018). Also, nutrition is the main source of absorption of CdCl 2. Vegetables and grains that grow in CdCl 2-contaminated soils or soils that are naturally high in CdCl 2 to be the main source of nonworking conditions exposure (Chunhabundit, 2016). Tobacco plants selectively absorb CdCl 2 from the soil and tobacco consumption increases the level of CdCl 2 in the human body. CdCl 2 can enter the lungs through tobacco smoke (Ganguly et al., 2018) and then circulate CdCl 2 throughout the body. In the liver, CdCl 2 with proteins forms a complex that is eventually secreted by the kidneys (Shirriff & Heikkila, 2017). CdCl 2 concentration in the blood of smokers is 4-5 times and in kidney 2-3 times higher than nonsmokers (Mannino et al., 2004; Mazur et al., 2018). The half-life of cadmium in the blood is estimated at 75-128 days, which means that CdCl 2 is deposited in organs including the liver, kidney and reproductive system and is not excreted from the body (Thompson & Bannigan, 2008). CdCl 2 causes hepatotoxicity (Almeer et al., 2018), nephrotoxicity (Sadek et al., 2017) hematotoxicity (Pagano et al., 2017), cardiotoxicity (Shrivastava et al., 2019) and skeletal muscle injury (Al-Sawafi et al., 2017). Epidemiological studies have shown that CdCl 2 has negative effects on sex hormone concentrations, sperm parameters and male infertility (Olaniyan et al., 2018). Cd with rupture

Unfortunately, many medical staff in hospitals and referral centers became ill, and some died due to frequent encounters with patients and severe cases of the disease. In the meantime, the issue of the spread of nosocomial infections should never be overlooked, and it should be thought that all attention should be focused on coronavirus, as the interaction between the virus and other strains of nosocomial infections is completely unknown. These measures are especially important in intensive care units for the care of Covid-19 patients, because the spread of this infection in these wards is strongly and exponentially associated with high mortality due to the disease. The outbreak of Covid-19 disease affected almost every country in the world, leading to more than 44 million cases and 1.2 million deaths by the end of October 2020. Another important point is the application of special and intensive protocols in the referral centers of patients in such a way as not only to prevent the spread of infection from disease to another patient but also to minimize the chances of infection of care and treatment personnel.

The present systematic review and meta-analysis study revealed that CT imaging features with high sensitivity can help diagnose patients with Covid-19 to be able to choose an appropriate treatment. In general, it seems that from a perspective, strategies and strategies to deal with the new corona virus worldwide, in four areas including strategies to combat social stigma caused by coronation, psychological such as strategies to combat fear and panic due to coronary heart disease, physical economic and in countries with religious places and behaviors and rituals, in the field of spiritual health can be examined. The aim of current study was to evaluate the radiological findings of patients with COVID-19. 534 studies were reviewed, of which the full text of 94 studies was reviewed and finally seven studies were selected for metaanalysis. Sensitivity and Specificity of ground glass opacity with other features in CT findings in diagnosis of COVID-19 was (ES, 0.92 95% CI 0.87, 0.96. P=0.00) and (ES, 0.67 95% CI 0.63, 0.72. P=0.00), Respectively. From another perspective, coping strategies with the new coronavirus can be considered in two categories: public coping strategies and public or private coping strategies. From the third point of view, coping strategies with Covid-19 can be divided into pre-and post-corona strategies. It seems that future review studies on issues such as: Critical evaluation of other new coronavirus coping strategies from different perspectives and based on the above divisions will pave the way for policymakers, officials and non-governmental organizations in the field of Covid-19 struggle.
