BOUNCE: Sentiment classification in Twitter using rich feature sets

The widespread use of Twitter makes it very interesting to determine the opinions and the sentiments expressed by its users. The shortness of the length and the highly informal nature of tweets render it very difficult to automatically detect such information. This paper reports the results to a challenge, set forth by SemEval-2013 Task 2, to determine the positive, neutral, or negative sentiments of tweets. Two systems are explained: System A for determining the sentiment of a phrase within a tweet and System B for determining the sentiment of a tweet. Both approaches rely on rich feature sets, which are explained in detail.

Türkiye’de bulunan yoğun bakımlarda sabun, kağıt havlu ve alkol bazlı el dezenfektanı yeterli mi?: Phokai çalışması sonuçları

Introduction: Hand hygiene is one of the most effective infection control measures to prevent the spread of healthcare-associated infections (HCAI). Water, soap, paper towel and hand disinfectant must be available and adequate in terms of effective hand hygiene. The adequacy of hand hygiene products or keeping water-soap and paper towel is still a problem for many developing countries like Turkey. In this multicenter study, we analyzed the adequacy in number and availability of hand hygiene products.Materials and Methods: This study was performed in all intensive care units (ICUs) of 41 hospitals (27 tertiary-care educational, 10 state and four private hospitals) from 22 cities located in seven geographical regions of Turkey. We analyzed water, soap, paper towel and alcohol-based hand disinfectant adequacy on four different days, two of which were in summer during the vacation time (August, 27th and 31st 2016) and two in autumn (October, 12th and 15th 2016).Results: The total number of ICUs and intensive care beds in 41 participating centers were 214 and 2357, respectively. Overall, there was no soap in 3-11% of sinks and no paper towel in 10-18% of sinks while there was no alcohol-based hand disinfectant in 1-4.7% of hand disinfectant units on the observation days. When we compared the number of sinks with soap and/or paper towel on weekdays vs. weekends, there was no significant difference in summer. However, on autumn weekdays, the number of sinks with soap and paper towel was significantly lower on weekend days (p<0.0001, p<0.0001) while the number of hand disinfectant units with alcohol-based disinfectant was significantly higher (p<0.0001).Conclusion: There should be adequate and accessible hand hygiene materials for effective hand hygiene. In this study, we found that soap and paper towels were inadequate on the observation days in 3-11% and 10-18% of units, respectively. Attention should be paid on soap and paper towel supply at weekends as well

Withdrawal of Staphylococcus aureus from intensive care units in Turkey

WOS: 000326241700021PubMed ID: 23663858Background: In the past, Staphylococcus aureus infections have displayed various patterns of epidemiologic curves in hospitals, particularly in intensive care units (ICUs). This study aimed to characterize the current trend in a nationwide survey of ICUs in Turkey. Methods: A total of 88 ICUs from 36 Turkish tertiary hospitals were included in this retrospective study, which was performed during the first 3 months of both 2008 (period [P] 1) and 2011 (P2). A P value <=.01 was considered significant. Results: Although overall rates of hospital-acquired infection (HAI) and device-associated infection densities were similar in P1 and P2, the densities of HAIs due to S aureus and methicillin-resistant S aureus (MRSA) were significantly lower in P2 (P < .0001). However, the proportion of HAIs due to Acinetobacter was significantly higher in P2 (P < .0001). Conclusions: The incidence of S aureus infections is declining rapidly in Turkish ICUs, with potential impacts on empirical treatment strategies in these ICUs.

Mortality risk factors among critically ill children with MIS-C in PICUs: a multicenter study

Background: This study evaluated of clinical characteristics, outcomes, and mortality risk factors of a severe multisystem inflammatory syndrome in children admitted to a the pediatric intensive care unit. Methods: A retrospective multicenter cohort study was conducted between March 2020 and April 2021 at 41 PICUs in Turkey. The study population comprised 322 children diagnosed with multisystem inflammatory syndrome. Results: The organ systems most commonly involved were the cardiovascular and hematological systems. Intravenous immunoglobulin was used in 294 (91.3%) patients and corticosteroids in 266 (82.6%). Seventy-five (23.3%) children received therapeutic plasma exchange treatment. Patients with a longer duration of the PICU stay had more frequent respiratory, hematological, or renal involvement, and also had higher D-dimer, CK-MB, and procalcitonin levels. A total of 16 patients died, with mortality higher in patients with renal, respiratory, or neurological involvement, with severe cardiac impairment or shock. The non-surviving group also had higher leukocyte counts, lactate and ferritin levels, and a need for mechanical ventilation. Conclusions: In cases of MIS-C, high levels of D-dimer and CK-MB are associated with a longer duration of PICU stay. Non-survival correlates with elevated leukocyte counts and lactate and ferritin levels. We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality. Impact: MIS-C is a life-threatening condition.Patients need to be followed up in the intensive care unit.Early detection of factors associated with mortality can improve outcomes.Determining the factors associated with mortality and length of stay will help clinicians in patient management.High D-dimer and CK-MB levels were associated with longer PICU stay, and higher leukocyte counts, ferritin and lactate levels, and mechanical ventilation were associated with mortality in MIS-C patients.We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality

Leading Infectious Diseases Problems in Turkey

Clin Microbiol Infect 2012; 18: 10561067 Abstract Turkey has significant geographical and socio-economic differences throughout a vast area of the country. These characteristics affect the epidemiology of infectious diseases, some of which are rarely seen in western Europe. However, effectively implemented control measures have resulted in decreased rates of many community-acquired infections, including tuberculosis and malaria, that were major health problems only a few decades ago. There are high rates of antimicrobial resistance in various nosocomial isolates of Gram-positive and Gram-negative bacteria. A recently implemented, nationwide, electronic resistance surveillance system in hospitals is expected to produce reliable data, and possibly will help to develop an effective strategy to decrease antimicrobial resistance in bacteria that currently plague many tertiary-care hospitals in the country. This article summarizes the most frequently encountered community-acquired infections, and gives an overview of current antimicrobial resistance in both outpatient and hospital settings in Turkey.WoSScopu
