Tetanus immunization among healthcare professionals: cross-sectional study in Turkey.

INTRODUCTION: Vaccine-preventable diseases can be effectively managed through timely vaccine booster doses. In this study, the tetanus vaccination status of healthcare professionals and their level of knowledge about tetanus vaccination were investigated. METHODOLOGY: The data were obtained through a survey questionnaire from 336 healthcare professionals. The survey participants were recruited on a voluntary basis among the personnel working in a tertiary hospital between 1 July 2021 and 30 September 2021. The participants were asked about their tetanus vaccination status and general awareness about the tetanus vaccine. RESULTS: The survey participants included nurses (41.4%, n = 139), doctors (39.9%, n = 134) and support unit personnel (18.8%, n = 63). The support unit personnel had insufficient knowledge about military service period, pregnancy period, vaccination of women aged 15-49 years, and the necessity of booster tetanus vaccine every 10 years. Interestingly, the nurses had significantly inadequate knowledge of geriatric tetanus vaccination. CONCLUSIONS: Although the tetanus immunization program is widely implemented throughout the country, our study concluded that it is necessary to educate healthcare professionals on the importance of the tetanus vaccine.

Two Cases of Crimean-Congo Hemorrhagic Fever Detected in a Non-endemic Feast of Sacrifice

Crimean-Congo hemorrhagic fever (CCHF) is a viral zoonotic infectious disease transmitted by ticks, accompanied by fever, bleeding, myalgia, weakness and similar non-specific symptoms, and can have an acute and serious course. In this article, two CCHF cases seen during the Coronavirus disease-2019 (COVID-19) pandemic in a non-endemic province are described. The common feature of both cases; contact with animals in the endemic region during the feast of sacrifice, non-specific symptoms, liver function test, lactate dehydrogenase and creatine phosphokinase elevation, leukopenia and thrombocytopenia. Especially during the COVID-19 pandemic, tick and livestock contact of patients with non-specific symptoms should be questioned.

In Vitro evaluation of thymoquinone on apoptosis and oxidative DNA damage in high glucose condition.

The study was planned to investigate the effects of thymoquinone (TQ), which is a compound in N. sativa, on caspase dependent apoptosis and oxidative DNA damage in high glucose treated PC12 cells. PC12 cells were treated with high glucose (G1-150 mM, G2-250 mM, G3-350 mM), TQ (20 µM), and their combinations. Oxidative DNA damage (8-OHdG (8-Oxo-2'-deoxyguanosine)), and apoptosis (caspase 3, caspase 8, caspase 9 enzymes and M30 protein) parameters were analyzed with ELISA. The 8-OHdG levels decreased in all combination groups compared to the control (p≤0.001). There was no statistically significant difference between caspase 3 and 9. Caspase 8 in TQ, G3, TQG1, TQG2 groups were higher than the control (p≤0.002). Low M30 levels were observed in TQG1 group (p≤0.002). In conclusion, it was observed that in PC12 cell line treated with the high glucose concentrations, TQ administration had a statistically significant effect on oxidative DNA damage and some apoptotic parameters (caspase 8 and M30 protein).
