(AUC= 0.680, p= 0.02). Median serum YKL-40 level was the highest in PPPEs (351.4 ng/mL) and the lowest in TBPEs (114.2 ng/mL) (p= 0.01). For a cut-off level of 284 ng/mL, it differentiated PPPEs from TBPEs with 61% sensitivity and 100% specificity (AUC= 0.830, p= 0.01). In TBPEs, pleural/serum YKL-40 ratio was strongly related with pleural ADA (r= 1, p= 0.04).

Pleural YKL-40 may be useful for differentiating exudates and detecting PMEs. Serum YKL-40 may be good diagnostic biomarker for differentiating PPPEs and TBPEs. Additionally, measuring serum and pleural YKL-40 and pleural ADA may be reliable way to diagnose TBPEs.

COPD is an inflammatory disease characterized by persistent respiratory symptoms and airflow limitation. Currently, it has been demonstrated in some studies that eosinophil and T helper-2 mediated inflammation play a role in the pathophysiology of COPD.

It was planned to evaluate eosinophilia, eosinophil/ neutrophil ratio (ENR), distribution of ENR according to GOLD groups, number of exacerbations in last year, relationship between ENR and the rate of ICS use in COPD patients, and the ENR cut-off value that predicts eosinophilic COPD. This study was planned prospectively in stable COPD patients between July 2017 and December 2017. All patients were divided into two groups as eosinophilic and non-eosinophilic group. Eosinophilia was considered to be > 2% of peripheric blood eosinophils.

A total of 206 stable COPD patients (127 eosinophilic and 79 noneosinophilic) were included. Age, gender, BMI, smoking history, mMrc score were statistically similar while average pack-year of smoking was significantlyshould be given to the use of ICS in COPD patients with high ENR and it can be used as a marker for predicting COPD exacerbation as COPD exacerbations are higher in patients with ENR.

Chronic Obstructive Pulmonary Disease (COPD) exacerbations contribute to the overall severity in individual patients because they are associated with airway inflammation, pulmonary function loss, decreased quality of life and increased mortality. Although, identifying frequent exacerbator patients is important due to severe outcomes associated with frequent exacerbator phenotype in COPD patients there is no single biomarker which can differentiate this phenotype. Iron responding protein-2 (IRP2) is the protein product of IREB2 gene, which is a COPD susceptibility gene that regulates cellular iron homeostasis and has a key role in hypoxic conditions. Previous research indicates that IREB2 expression in lung tissue is associated with spirometric measurements and emphysema in COPD. In this study, our aim was to investigate whether serum IRP2 levels were associated with frequent exacerbator phenotype, to evaluate whether IRP2 levels in serum are associated with pulmonary functions and selected systemic inflamma

Serum IRP2 level is significantly correlated with FEV1 mL but not with FEV1 % predicted and cannot be used to differentiate frequent exacer bator patients. Although IREB2 gene expressions in lung tissue and bronchoalveolar lavage results have significant associations with emphysema and FEV1/FVC, FEV1 %predicted in COPD patients, our results suggests serum IRP2 level is not as promising.

Palliative care is a multidisciplinary therapy formed by physical, social, psychological, cultural and spiritual support of patients and families. The aim of the present study is to compare the survival rates of the intensive care unit (ICU) and palliative care unit (PCU).

A retrospective observational cohort study was performed using the database of an intensive care unit. Patients with terminal illness admitted to the intensive care unit or palliative care unit were included in the study. find more Demographic data, comorbidities, time of admission, discharge and death were recorded. The survival estimation was completed using Kaplan Meier survival analysis.

A total of 112 patients were included in the study. Patients were divided into two groups where 60 patients (53.6%) were in Group ICU and 52 (46.4%) were in Group PCU. The Kaplan-Meier estimation of survival curves showed that the overall median time was 29 days. This result demonstrated that 50% of the patients was survived longer than 29 days, in which it was 12 days and 38 days for Group ICU and Group PCU, respectively (

The risk of tuberculosis is higher in cases who have used antiTNF treatments. link2 However, it is not clearly known whether there is a relationship between other biologic agents and the risk of developing tuberculosis or not. We aimed to investigate the prevalence of active tuberculosis among patients with rheumatic disease treated with biologic drugs.

The study was performed at a tertiary referral center from January 2015 to December 2019. A total of 2000 patients with rheumatic diseases were screened and 461 patients were enrolled in the study due to regular records. They were underwent LTBI screening tests and were followedup at least 1 year after TNF inhibitor treatment initiation.

The median age of all patients was 48 (min-max 19-80). 283 patients (61.3%) were female and 178 (38.7%) were male. The most common diseases were ankylosing spondylitis (67.2%), rheumatoid arthritis (26%) and psoriatic arthritis (5.2%). Anti-TNF treatments were given to 85.2% of all cases and other biologic treatments were given to 14.8%. Tuberculin skin test was applied to 429 patients and 70.4% positivity was found. Quantiferon-TB test was applied to 93 patients and 20.4% positivity was found. 320 patients were treated for LTBI due to positive tuberculin skin test and/or positive quantiferon-TB test. TB was developed in only one patient out of 393 patients who were treated with anti-TNF treatments and the the prevalence of TB development was found 255/100.000.

The incidence of tuberculosis was quite low in our patients with rheumatic disease who were receiving anti-TNF treatment compared to previous studies. Also, in patients who were using other biological treatments, no TB cases were developed.

SARS-CoV-2 (COVID-19), which emerged in Wuhan, China in December 2019, infected more than six million people in a short time. In COVID-19, the relationship of many laboratory parameters to morbidity and mortality has been defined. In our study, we aimed to determine the relationship of serum vitamin D level to clinical course and prognosis.

This study included 108 patients; 88 patients who stayed in Ataturk University and Erzurum City Hospital between March 24, 2020 and May 15, 2020, who were identified as COVID-19 by real-time PCR method from the nasopharyngeal swab and 20 asymptomatic voluntary medical personnel who tested negative for real-time PCR after routine check-up in our hospital.

In statistical analysis conducted between healthy control group and vitamin D levels of patients admitted due to COVID-19, it was observed that patients infected with COVID-19 had a lower level (p= 0.004). In 20 patients developing MAS, a lower level of vitamin D was observed (p= 0.004) compared to 68 patients who did not develop. In the comparison of vitamin D levels of the patients (n= 8) who developed exitus in their follow up due to COVID-19, it was observed that vitamin D levels were statistically significantly lower compared to the living (p= 0.009).

Due to COVID-19, pandemic, long-running quarantines caused insufficient use of sunlight and worsening of vitamin D deficiency. We wanted to draw attention again with our study to vitamin D which can be responsible for the heavy clinical course of COVID-19 and whose replacement is easy to apply.

The aim of this study is to investigate and report on the data regarding the clinical characteristics and outcomes of healthcare workers with COVID-19 at tertiary education hospitals from Turkey.

This was a single center, retrospective, descriptive and observational study using cross-sectional data, which were collected from confirmed COVID-19 patients at a tertiary education hospital. Patients' demographic and clinical characteristics, mortality rates, and the factors associated with hospitalization were analyzed.

By May 15, 2020, 480 patients were diagnosed with COVID-19 in our hospital where 49 (10.2%) of whom were HCWs. The mean age was 40.0 ± 8.45 (75.5% female). The most common symptoms were cough (32.7%), fever (30.6%), and myalgia (14.3%). Comorbidities were present in 32.7% of the patients. Most of the HCWs were nurses (53.1%) and physicians (18.4%), and the remaining 14 (28.6%) were cleaning and administrative staff. link3 The severity of the disease was mild in 65.3% and severe in 34.7% HCWs. Leukocyte, neutrophil, lymphocyte and platelet values were statistically lower in hospitalized patients. There was a statistically significant relationship between the presence of infiltration on the chest X-ray, and the patient's symptoms with the severity of the disease (respectively p= 0.002 and 0.009).

In conclusion, the frequency of COVID-19 in healthcare workers is high. The study presents the characteristics of HCWs infected with coronavirus from a single center in Turkey.

Intensive care physicians are increasingly involved in decision making about the prognosis of intensive care unit ICU patients. With this study; we aimed to evaluate the power of clinician foresight at prediction of mortality in patient at triage to intensive care and patient follow-up.

This study was conducted in ICUs located in various geographical regions of Turkey between January 1, 2017-April 30, 2017.The clinical research was planned as observational, multicenter, cross-sectional.

A total of 1169 intubated patients were followed in 37 different ICU. At the beginning of the follow-up we asked the physician who will follow the patient in the ICU to give a score for the probability of survival of the patients. Scoring included a total of 6 scores from 0 to 5, with the "0" the worst probability "5" being the best. According to this distribution, only 1 (0.9%) of 113 patients who were given 0 points survived. Three (6.1%) of 49 with the best score of 5 died. Survival rates were significantly different d in intensive care mortality scoring in addition to other laboratory and clinical parameters.

Prior studies of rapid response team (RRT) implementation for surgical patients have demonstrated mixed results with respect to reductions in poor outcomes. The aim of this study was to identify predictors of in-hospital mortality and hospital costs among surgical inpatients requiring RRT activation.

We analyzed data prospectively collected from May 2012 to May 2016 at The Ottawa Hospital. We included patients who were at least 18 years of age, who were admitted to hospital, who received either preoperative or postoperative care, and and who required RRT activation. We created a multivariable logistic regression model to describe mortality predictors and a multivariable generalized linear model to describe cost predictors.

We included 1507 patients. The in-hospital mortality rate was 15.9%. The patient-related factors most strongly associated with mortality included an Elixhauser Comorbidity Index score of 20 or higher (odds ratio [OR] 3.60, 95% confidence interval [CI] 1.96-6.60) and care designations excluding admission to the intensive care unit and cardiopulmonary resuscitation (OR 3.
