Objective: The aim of this study was to determine the prevalence of the causative agents of multi-drug resistant bacteria in pneumonia and also evaluate their mortality rates in the intensive care unit (ICU)., Methods: This study included all the cases of hospital-acquired pneumonia (HAP) and community-acquired pneumonia (CAP) in the ICU between the period of January 2018 and December 2019., Results: Seventy-four patients in pneumonia were included. Mortality rate was 45.9%. In patients with HAP had higher length of stay days in hospital and ICU, the use of sedative agents, sepsis rate and mortality rate as compared in patients with CAP (for all P < .05). Microorganism was identified in 27 (36.6%) of the patients. Respiratory samples were positive in 25.4% of patients with CAP and 60.8% of patients with HAP. Acinetobacter baumannii and Klebsiella pneumoniae were the most frequent aetiologic agents (40.7% and 22.2%, respectively). Acinetobacter baumannii was not susceptible to the third generation cephalosporin, piperacillin-tazobactam, carbapenem, fluoroquinolone and trimethoprim/sulfamethoxazole. Amongst gram-positive bacteria, the most common isolate was Staphylococcus aureus. The frequency of methicillin-resistant Staphylococcus aureus was 75% but these isolates were susceptible to vancomycin and tigecycline., Conclusion: The predominance of gram-negative agents was observed in pneumonia patients and because of the high resistance to antibiotics, treatment strategies need to be reconsidered in order to improve the poor prognosis., (© 2020 John Wiley & Sons Ltd.)

Aim: The aim of this study was to investigate the ABO and Rh blood group distribution and clinical characteristics in patients with COVID-19., Materials and Methods: The clinical characteristics and blood groups of 1667 patients who were hospitalised because of COVID-19 (with a positive PCR test) between 16 March and 10 July were reviewed cross-sectionally., Results: When blood groups of patients diagnosed with COVID-19 and control group were compared, it was observed that there was an increase in the number of COVID-19 patients with blood groups A and AB, decrease in the number of COVID-19 patients with blood group O, a statistically significant increase in the number of individuals with blood group A in COVID-19 patients compared with healthy individuals, and almost significant increase in the number of COVID-19 patients with blood group AB and a very significant decrease in the number of COVID-19 patients with blood group O., Conclusion: Our study has found that having blood group O may be protective, that blood group A may have greater susceptibility to the disease, but this does not affect the course of the disease and is not associated with mortality., (© 2020 John Wiley & Sons Ltd.)

Aim: As the COVID-19 pandemic has been spreading rapidly all over the world, there are plenty of ongoing works to shed on light to unknown factors related to disease. One of the factors questioned is also to be the factors affecting the disease course. In this study, our aim is to determine the factors that affect the course of the disease in the hospitalised patients because of COVID-19 infection and to reveal whether the seasonal change has an effect on the disease course., Methods: Our study was conducted on 1950 PCR test positive patients who were hospitalised for COVID-19 disease between March 16 and July 15., Results: As the seasonal temperature increases, decrease in WBC, PLT and albumin levels and increase in LDH and AST levels were observed. Risk of need for ICU has been found statistically significant (P < .05) with the increase in the age, LDH levels and CRP levels and with the decrease in the Ca and Albumin levels., Conclusions: It is predicted with these results that, seasonal change might have affects on the clinical course of the disease, although it has no affect on the spread of the disease. And it might beneficial to check biochemical parameters such as LDH, CRP, Ca and Albumin to predict the course of the disease., (© 2020 John Wiley & Sons Ltd.)
