Background: Sepsis, which is a common inflammatory response to severe infection, is one of the major causes of mortality in hospitalized patients. Sepsis, severe sepsis or sepsis syndrome, and eventually septic shock, may be seen in the development of infection. The aim of this study was to evaluate the short-term and long-term mortality in patients with severe sepsis and septic shock in centers with low antibiotic resistance. Methods: In this cross-sectional study, blood culture samples and peripheral blood samples were taken from all patients for para-clinical tests. The severity of severe sepsis and septic shock was assessed by the APACHE II and SOFA clinical criteria. Sepsis risk factors and primary causes of sepsis were recorded. Results: From 100 patients, 55% had severe sepsis and 45% had septic shock. SOFA24h and SOFA96h scores were significantly higher in patients with septic shock. The most common primary cause of sepsis was related to abdominal infections with a frequency of 42%. The frequency of confirmed positive blood culture was 53%. The most commonly isolated pathogen was E.coli with a frequency of 66%. Short-term mortality was 29% and longterm mortality was 28.2%. Conclusion: The main risk factors affecting the mortality of patients were age-related septic shock, cardiovascular disease; hypertension, immunosuppression, and SOFA score. [ABSTRACT FROM AUTHOR]

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is known to be the most resistant pathogen in hospitals, which can infect both the health workers and patients. The most common site for colonization is the anterior part of the nose and throat.In order to prevent and control the infection and the role of medical personnel as a carrier for transmitting infection, the aim of this study was to determine the amount of nasal colonization with MRSA in the medical staff of Sina and Imam Reza Hospital in Tabriz. Methods: The present cross-sectional study evaluated 400 participants. From the entire medical staff of Sina and imam Reza hospitals in 2017 who were willing to participate in this study. Sterile swabs inserted in to the anterior region of the nose. Then swabs were immediately cultured in a laboratory in mannitol salt agar blood agar for 24 hours and incubated for 48 to 72 hours, to determine the MRSA strains, Cefoxitin disc method was used in Muller Hinton Agar culture media. Descriptive statistical methods and Chi² test was used for statistical analyses. P value less than 0.05 was considered statistically significant. Results: 55% of the health care workers (220) were carriers of Staphylococcus aureus, mean age was 38.27 ± 8.72 years and 61.8% were male. Internal ward health care workers were common Staphylococcus aureus carriers and diabetes was the most common systemic disease. Out of 37.8% had a history of previous hospital admission and 87.2% had antibiotic use. Also, methicillin resistance was observed in out of 32.7% of subjects. Conclusion: Constant control of infectious agents and the use of Proper antibiotics can be effective in controlling carriers and even drug-resistant cases [ABSTRACT FROM AUTHOR]
