Evidence of historical seismicity and volcanism in the Armenian Highland (from Armenian and other sources)
This work presents a summary on the development of studies of historical earthquakes in Armenia and adjacent parts of Turkey and Iran. Since ancient times, this region has been an arena where active geodynamic and seismic history intermingled with no less active and dynamic evolution of human cultures and societies. A long-term
historical record in this region beginning as early as the 8th century B.C. provides abundant evidence that can make an inestimable contribution to studies of historical seismicity and volcanism in the area. We discuss the main research methodology and sources used, and dwell on the principal catalogues of historical earthquakes compiled to date
Surveillance of Antibiotic Prescribing in Intensive Care Units in Poland
Antibiotic use and microbial resistance in health care-associated infections are increasing globally and causing health care problems. Intensive Care Units (ICUs) represent the heaviest antibiotic burden within hospitals, and sepsis is the second noncardiac cause of mortality in ICUs. Optimizing appropriate antibiotic treatment in the management of the critically ill in ICUs became a major challenge for intensivists. We performed a surveillance study on the antibiotic consumption in 108 Polish ICUs. We determined which classes of antibiotics were most commonly consumed and whether they affected the length of ICU stay and the size and category of the hospital. A total of 292.389 defined daily doses (DDD) and 192.167 patient-days (pd) were identified. Antibiotic consumption ranged from 620 to 3960 DDD/1000 pd. The main antibiotic classes accounted for 59.6% of the total antibiotic consumption and included carbapenems (17.8%), quinolones (14%), cephalosporins (13.7%), penicillins (11.9%), and macrolides (2.2%), respectively, whereas the other antibiotic classes accounted for the remainder (40.4%) and included antifungals (34%), imidazoles (20%), aminoglycosides (18%), glycopeptides (15%), and polymyxins (6%). The most consumed antibiotic classes in Polish ICUs were carbapenems, quinolones, and cephalosporins, respectively. There was no correlation between antibiotic consumption in DDD/1000 patient-days, mean length of ICU stay, size of the hospital, size of the ICU, or the total amount of patient-days. It is crucial that surveillance systems are in place to guide empiric antibiotic treatment and to estimate the burden of resistance. Appropriate use of antibiotics in the ICU should be an important public health care issue
Characteristics and risk factors for 28-day mortality of hospital acquired fungemias in ICUs: data from the EUROBACT study
Background: To characterize and identify prognostic factors for 28-day mortality among patients with hospital-acquired fungemia (HAF) in the Intensive Care Unit (ICU)
Characteristics and risk factors for 28-day mortality of hospital acquired fungemias in ICUs: data from the EUROBACT study
Background: To characterize and identify prognostic factors for 28-day
mortality among patients with hospital-acquired fungemia (HAF) in the
Intensive Care Unit (ICU).
Methods: A sub-analysis of a prospective, multicenter non-representative
cohort study conducted in 162 ICUs in 24 countries.
Results: Of the 1156 patients with hospital-acquired bloodstream
infections (HA-BSI) included in the EUROBACT study, 96 patients had a
HAF. Median time to its diagnosis was 20 days (IQR 10.5-30.5) and 9 days
(IQR 3-15.5) after hospital and ICU admission, respectively. Median time
to positivity of blood culture was longer in fungemia than in bacteremia
(48.7 h vs. 38.1 h; p = 0.0004). Candida albicans was the most frequent
fungus isolated (57.1 %), followed by Candida glabrata (15.3 %) and
Candida parapsilosis (10.2 %). No clear source of HAF was detected in
33.3 % of the episodes and it was catheter-related in 21.9 % of them.
Compared to patients with bacteremia, HAF patients had a higher rate of
septic shock (39.6 % vs. 21.6 %; p = 0.0003) and renal dysfunction (25
% vs. 12.4 %; p = 0.0023) on admission and a higher rate of renal
failure (26 % vs. 16.2 %; p = 0.0273) at diagnosis. Adequate treatment
started within 24 h after blood culture collection was less frequent in
HAF patients (22.9 % vs. 55.3 %; p < 0.001). The 28-day all cause
fatality was 40.6 %. According to multivariate analysis, only liver
failure (OR 14.35; 95 % CI 1.17-175.6; p = 0.037), need for mechanical
ventilation (OR 8.86; 95 % CI 1.2-65.24; p = 0.032) and ICU admission
for medical reason (OR 3.87; 95 % CI 1.25-11.99; p = 0.020) were
independent predictors of 28-day mortality in HAF patients.
Conclusions: Fungi are an important cause of hospital-acquired BSI in
the ICU. Patients with HAF present more frequently with septic shock and
renal dysfunction on ICU admission and have a higher rate of renal
failure at diagnosis. HAF are associated with a significant 28-day
mortality rate (40 %), but delayed adequate antifungal therapy was not
an independent risk factor for death. Liver failure, need for mechanical
ventilation and ICU admission for medical reason were the only
independent predictors of 28-day mortality
Characteristics and risk factors for 28-day mortality of hospital acquired fungemias in ICUs : data from the EUROBACT study
The EUROBACT study was designed by the infection section of the ESICM.The study was endorsed by the European Critical Care Research Network(ECCRN) in May 2009 and received the Clinical Research Award with aresearch grant of€20,000 from the ECCRN in November 2011.To characterize and identify prognostic factors for 28-day mortality among patients with hospital-acquired fungemia (HAF) in the Intensive Care Unit (ICU).

Variations in end-of-life practices in intensive care units worldwide (Ethicus-2): a prospective observational study.
BACKGROUND
End-of-life practices vary among intensive care units (ICUs) worldwide. Differences can result in variable use of disproportionate or non-beneficial life-sustaining interventions across diverse world regions. This study investigated global disparities in end-of-life practices.
METHODS
In this prospective, multinational, observational study, consecutive adult ICU patients who died or had a limitation of life-sustaining treatment (withholding or withdrawing life-sustaining therapy and active shortening of the dying process) during a 6-month period between Sept 1, 2015, and Sept 30, 2016, were recruited from 199 ICUs in 36 countries. The primary outcome was the end-of-life practice as defined by the end-of-life categories: withholding or withdrawing life-sustaining therapy, active shortening of the dying process, or failed cardiopulmonary resuscitation (CPR). Patients with brain death were included in a separate predefined end-of-life category. Data collection included patient characteristics, diagnoses, end-of-life decisions and their timing related to admission and discharge, or death, with comparisons across different regions. Patients were studied until death or 2 months from the first limitation decision.
FINDINGS
Of 87 951 patients admitted to ICU, 12 850 (14·6%) were included in the study population. The number of patients categorised into each of the different end-of-life categories were significantly different for each region (p<0·001). Limitation of life-sustaining treatment occurred in 10 401 patients (11·8% of 87 951 ICU admissions and 80·9% of 12 850 in the study population). The most common limitation was withholding life-sustaining treatment (5661 [44·1%]), followed by withdrawing life-sustaining treatment (4680 [36·4%]). More treatment withdrawing was observed in Northern Europe (1217 [52·8%] of 2305) and Australia/New Zealand (247 [45·7%] of 541) than in Latin America (33 [5·8%] of 571) and Africa (21 [13·0%] of 162). Shortening of the dying process was uncommon across all regions (60 [0·5%]). One in five patients with treatment limitations survived hospitalisation. Death due to failed CPR occurred in 1799 (14%) of the study population, and brain death occurred in 650 (5·1%). Failure of CPR occurred less frequently in Northern Europe (85 [3·7%] of 2305), Australia/New Zealand (23 [4·3%] of 541), and North America (78 [8·5%] of 918) than in Africa (106 [65·4%] of 162), Latin America (160 [28·0%] of 571), and Southern Europe (590 [22·5%] of 2622). Factors associated with treatment limitations were region, age, and diagnoses (acute and chronic), and country end-of-life legislation.
INTERPRETATION
Limitation of life-sustaining therapies is common worldwide with regional variability. Withholding treatment is more common than withdrawing treatment. Variations in type, frequency, and timing of end-of-life decisions were observed. Recognising regional differences and the reasons behind these differences might help improve end-of-life care worldwide.
