WHO has determined the policy topics that countries should implement to prevent this epidemic, known as MPOWER for short. It follows the activities of countries for these topics and publishes them in annual reports. As a result of the studies carried out under the leadership of WHO, the use of tobacco products by countries has decreased. The use of tobacco products, which was 32.7% in the world in 2000, is expected to decrease to 20.4% in 2025. In our country, it is predicted to decrease from 32.9% to 29.9% in the same way. Our country has successfully implemented the policy package within the scope of WHO’s Framework Convention on Tobacco Control, and as a result, it has become one of the two countries that fully implemented MPOWER measures at the highest level of success. Companies that manufacture and sell tobacco products have launched new products in the face of these developments. The most popular of these products are Electronic Nicotine/ Non-Nicotine Delivery Systems (ENDS/ENNDS) and Heated Tobacco Products (HTPs). The fact that the target audience of these new products is mostly 13 years old and over and their rapid spread among young people has led to the opening of new fronts in the war against tobacco. The rapid spread of new products was influenced by the fact that their appearance was designed to attract young people, presented as an alternative to cigarettes, and created a perception of less harm. Studies have shown that these products are not harmless. WHO has stated that reducing the damage does not reduce the risk in terms of human health. The second most important factor affecting the use is the different perspectives and legal regulations of countries on these new products. While some countries have banned it, some countries have allowed its sale. This review aims to provide detailed In this review, about the legal regulations made in our country regarding novel and emerging nicotine and tobacco products.","PeriodicalId":35553,"journal":{"name":"Turk hijiyen ve deneysel biyoloji dergisi.

The deoxycorticosterone acetate (DOCA)-salt model is an experimental model that is widely used in the investigation of the pathogenesis of essential hypertension. Although this model can successfully mimic essential hypertension in humans, both the rate and magnitude of blood pressure increase with unilateral nephrectomy does not fully reflects the clinical situation in most hypertensive patients. In this study, it was investigated the effects of prolonged administration of DOCA-salt without nephrectomy on blood pressure, body weight, heart and kidney functions of rats. atrium and left papillary muscle tissues were isolated from rats. Isoprenaline, phenylephrine and acethylcholine-induced rhythmic activity and contractions of tissues were recorded in organ bath. Blood urea nitrogen (BUN) and creatinine levels were measured in plasma samples. Results: 12 weeks DOCA-salt administration without nephrectomy were significantly elevated systolic blood pressure of rats. The DOCA-salt application did not cause a decrease in the body weight of the rats. While the right atrium was not affeced to acethylcholine; the phenylephrine-induced alpha adrenergic receptor mediated contractile responses were increased and the isoprenaline-induced beta adrenergic receptor-mediated contractile responses were decreased in hypertensive rats. The DOCA-salt administration increased plasma BUN and creatinine levels of rats. Conclusion: These findings suggest that 12 weeks DOCA-salt administration without nephrectomy caused cardiac and renal changes associated with hypertension and could be used in hypertension studies as a noninvasive animal model.","PeriodicalId":35553,"journal":{"name":"Turk hijiyen ve deneysel biyoloji dergisi.

Infection of healthcare workers with SARS-CoV-2 poses a potential risk of infection for other healthcare workers, patients and their families. The viral load measure in the sample is determined as the cycle threshold (Ct) with the RT-qPCR method. It has been reported that the RT-qPCR Ct value may be related to the severity and potential contagiousness of the infection. In this study, it was aimed to evaluate the relationships between socio-demographic factors, COVID-19 symptoms and Ct value in SARS-CoV-2 RT-qPCR positive healthcare workers. METHODS: In this study, 300 healthcare workers with positive SARS-CoV-2 RT-qPCR test were included. SARS-CoV-2 RT-qPCR test was performed from nasopharyngeal and oropharyngeal swab samples with Bio-speedy SARS-CoV-2 RT-qPCR (Bioeksen, Turkey) kit. The RT-qPCR Ct value results of healthcare staff patients were classified as low, medium and high, socio-demographic characteristics and the risk of viral spread was evaluated. RESULTS: The rate of those who showed at least one symptom among the 300 health personnel included in the study was 88.3% (n=265) and the most common symptoms were muscle-joint pain 39.7%, fatigue 33% and sore throat 30.7%. The median RT-qPCR Ct value was determined as 23.17(19.3-29.4) and Ct value was found to be low (<24.0) in 59% of healthcare personnel. In addition, the Ct value of the personnel working in the administrative units was found to be lower than those working in the COVID-19 polyclinic, service and intensive care unit (p=0.020). Those who had fever and at least one of the COVID-19 symptom (fever, cough, respiratory distress) group had a lower Ct value than those who did not (p=0.008, p=0.019, respectively). When the possible source of transmission was evaluated, it was determined that 22% of the health personnel were infected during patient care, 21% from other health personnel and 23.3% from non-hospital sources. DISCUSSION AND CONCLUSION: Our results have shown that most of the SARS-CoV-2 transmission seen in healthcare workers occurs within the hospital, but more viral load is exposed in out-of-hospital contacts. In addition, it has been observed that administrative personnel who do not have contact with patients can be a potential source of transmission. This situation has reaffirmed that PPE usage rules should be followed in order to reduce the risk of transmission in healthcare personnel and that personnel working outside the clinic should follow the mask and distance rules during their contact with their colleagues. It was determined that the Ct value was lower (higher viral load) in the presence of any of the symptoms of fever, cough, respiratory distress and fatigue in healthcare workers. In the presence of these symptoms, PCR testing of healthcare workers and taking necessary isolation measures until the test resu","PeriodicalId":35553,"journal":{"name":"Turk hijiyen ve deneysel biyoloji dergisi.

An ANN is built from a network of linked units or nodes known as artificial neurons, which are roughly modeled after the neurons in the human brain. Each link, like synapses in a human brain, has the ability to send a signal to other neurons. The connections are referred to as edges. Neurons and edges usually have a weight that changes as learning progresses. The weight changes the intensity of the signal at a connection. Artificial neural networks have found applications in a wide range of fields due to their capacity to recreate and simulate nonlinear phenomena. System identification and control, medical diagnostics, data mining, visualization, machine translation, distinguishing highly invasive cancer cell lines from less invasive lines using simply cell shape information, and many more domains are examples of application areas. In this study, ANN analysis was utilized by us to forecast the total cost of therapy or the prognosis of severe COVID-19 the patients in the intensive care unit (ICU). Methods: The parameters such as ages, and the other biochemical parameters that affect the staying periods (days) of COVID-19 infected patients in ICU were evaluated by using an ANN analysis. For this a computer program, Pythia®, was used to develop ANN models. Real data was used for that selected patients in this study. Results: The real data obtained from the ICU and gave to the computer as initial parameters. The computer program gave 15 neurons for the first level, one neurons for the second level as the most suitable model for the prediction (SSD = 0.000995). This program predicts a total cost 144.930,94 Turkish Lira (27.300 USD) where the real cost 142.234,06 Turkish Lira (26.792 USD) for the real patient in 2019. This relation was found to be good to predict the possible affected parameters on staying times. Conclusion: The ANN model developed and released in this research does not necessitate any experimental parameters. Besides, ANN has the ability to deliver helpful and exact prediction or information regarding the expense of COVID-19 patients in ICU. © 2022.
