Objective This study was designed to investigate the effects of Desert Dust Storms and Climatological Factors on Mortality and Morbidity of Cardiovascular Diseases admitted to emergency department in Gaziantep. Method Hospital records, obtained between September 01, 2009 and January 31, 2014, from four state hospitals in Gaziantep, Turkey, were compared to meteorological and climatological data. Statistical analysis was performed by Statistical Package for the Social Science (SPSS) for windows version 24.0. Results 168,467 patients were included in this study. 83% of the patients had chest pain and 17% of patients had cardiac failure (CF). An increase in inpatient hospitalization due to CF was observed and corresponded to the duration of dust storms measured by number of days. However, there was no significant increase in emergency department (ED) presentations. There was no significant association of cardiac related mortality and coinciding presence of a dust storm or higher recorded temperature. The association of increases in temperature levels and the presence of dust storms with “acute coronary syndrome- (ACS-) related emergency service presentations, inpatient hospitalization, and mortality” were statistically significant. The relationship between the increase in PM10 levels due to causes unrelated to dust storms and the outpatient application, admission, and mortality due to heart failure was not significant. The increase in particle matter 10 (PM) levels due to causes outside the dust storm caused a significant increase in outpatient application, hospitalization, and mortality originated from ACS. Conclusion Increased number of dust storms resulted in a higher prevalence of mortality due to ACS while mortality due to heart failure remained unchanged. Admission, hospitalization, and mortality due to chest pain both dependent and independent of ACS were increased by the presence of dust storms, PM10 elevation, and maximum temperature.

INTRODUCTION: The primary aim of the study was to compare the laboratory and radiological parameters of COVID-19 positive and negative patients confirmed by Real-Time Reverse Transcription Polymerase Chain Reaction (RT-PCR), and Chest Computed Tomography (CCT) of patients admitting with the suspicion of COVID-19. The secondary purpose of the study was to find objective parameters to speed up the clinician for further examination, treatment or referral decision in COVID-19 suspicion. MATERIAL AND METHODS: A total of 61 COVID-19 suspected patients were evaluated in the study. Swab samples were taken for RT-PCR analysis. CCT was taken for 42 patients who described dyspnea. According to CCT and RT-PCR results, the patient population was divided into 2 groups as COVID-19 positive group (n = 32); and COVID-19 negative group (n = 29). Between two groups; demographic, clinical, laboratory and radiological parameters were compared. RESULTS: Male gender (p = 0.03), PLR value (p = 0.021) and CO-RADS scores were higher in the COV-ID-19 positive group. Oxygen saturation (SaO 2) (p = 0.027) and PCT, WBC, Neutrophil count, Lymphocyte count values were significantly low in COVID-19 positive group (p = 0.03, p = 0.001, p = 0.017, p = 0.021, respectively). PLR showed a positive correlation with fever, CRP, neutrophil count and NLR, which are indicators of inflammation. CONCLUSIONS: SaO 2 , WBC, lymphocyte count, neutrophil count and low PCT levels, and PLR elevation showed a significant difference in COVID-19 patients in our retrospective cohort study examining the Turkish population. We believe that these results will allow clinicians to make quick decisions in patient management more simply.
