    DergiPark: 637912trakyasobedAraştırmanın ilgilendiği sanat işleri, sanat tarihi çalışmalarında “duvar resmi” terim anlamının içine dâhil olmaktadır. İncelenen resimler, “geçiş döneminin” artık fotoğraf teknolojisinin de bu uygulamada rolü olduğu 19. yy. ‘ın son çeyreğine aittir. Edirne’de konak maliki merhum Şücaattin Dumlu ismi dolayısıyla Dumlu Konağı olarak geçen günümüzde metruk halde bulunan tarihi konaktaki toplamda 4 adet duvar resmi, estetik değerleri, mekânla kurduğu ilişkileri ve sanat tarihsel özellikleriyle incelenmektedir.The artworks that the research is interested in are included in the meaning of the terms “wall paintings” or “mural paintings” in art history studies. The paintings; we investigate, belong to the last quarter of the 19th century, which is at the end of the historical slice of “the transition period” of Turkish Art History; at the time, the practice found a contribution from the technology of photography. In this research, we study a totally of 4 wall paintings (some of which are ruined, the rests are about to be ruined) in terms of the aesthetic values, relations with the architectural space, and art historical features; on the historic mansion, named Dumlu Mansion because of the name of former owner Şücaattin Dumlu, which is currently in a deserted state. In addition, we delve into the history of the mansion, which is recently developed -a controversial topic-, by using historical and art historical research

    Purpose: Acinetobacter was known as a saprophytic colonizer, yet it is considered an important etiologic agent which is isolated from hospital-acquired infections. In this study, we aimed to investigate fatality rates, factors for fatality of Acinetobacter infections and relationship between combination therapies and survival.Patients and Methods: We evaluated patients with Acinetobacter infection in ICU for demographic and clinical characteristics, combination therapies and adverse effects of these therapeutic options, retrospectively.Results: Ninety-one patients with proved Acinetobacter infection were included in this study. We found that the fatality rate of Acinetobacter infection in ICU was 56%. Advanced age, carbapenem resistance and Acinetobacter isolation from respiratory secretions were significantly related with fatality.  We found that carbapenem resistance increased steadily during a 5 year period, fatality rates significantly decreased with combination therapies including aminoglycosides. There wasn’t significant relation between colistin therapy and survival in patients with Acinetobacter infections.Conclusion: The patients should be well-assessed in terms of fatality risk factors in case of Acinetobacter infections that occur in the intensive care units. The empirical antibiotic treatment started earlier based on such risk factors may decrease fatality. The antimicrobial combinations including aminoglycoside may be considered more in order to the local resistance data

    17β-estradiol promotes extracellular vesicle release and selective miRNA loading in ERα-positive breast cancer

    The causes and consequences of abnormal biogenesis of extracellular vesicles (EVs) are not yet well understood in malignancies, including in breast cancers (BCs). Given the hormonal signaling dependence of estrogen receptor–positive (ER+) BC, we hypothesized that 17β-estradiol (estrogen) might influence EV production and microRNA (miRNA) loading. We report that physiological doses of 17β-estradiol promote EV secretion specifically from ER+ BC cells via inhibition of miR-149-5p, hindering its regulatory activity on SP1, a transcription factor that regulates the EV biogenesis factor nSMase2. Additionally, miR-149-5p downregulation promotes hnRNPA1 expression, responsible for the loading of let-7’s miRNAs into EVs. In multiple patient cohorts, we observed increased levels of let-7a-5p and let-7d-5p in EVs derived from the blood of premenopausal ER+ BC patients, and elevated EV levels in patients with high BMI, both conditions associated with higher levels of 17β-estradiol. In brief, we identified a unique estrogen-driven mechanism by which ER+ BC cells eliminate tumor suppressor miRNAs in EVs, with effects on modulating tumor-associated macrophages in the microenvironment

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    Objective: Intensive care units are a hospital’s section where hospital infections and resistant microorganisms are most commonly seen. In this study it was aimed to determine the microorganisms which were isolated from various clinical specimens of the patients in intensive care units for a year and antibiotic susceptibility of the microorganisms. Materials and Methods: MALDI TOF MS and BD Phoenix system were used for the identification of bacteria, antibiotic sensitivities were evaluated by Kirby-Bauer disk diffusion method and BD Phoenix system in accordance with the Clinical and Laboratory Standards Institute recommendations. Results: In this study, a total of 1163 microorganisms were obtained; 575 (49.4%) gram-negative bacteria (GNB), 556 (47.8%) gram-positive bacteria (GPB) and 32 Candida spp. (2.7%). Strains were produced from blood (488), urine (233), respiratory tract (224), sterile body fluid (88), wounds (68) and catheter samples (62). The most frequently isolated GNBs were found to be Acinetobacter baumannii 131 (11.2%), Klebsiella pneumoniae 109 (9.3%), Escherichia coli 91 (7.8%) in order of frequency. Extended-spectrum beta-lactamase production was observed in 16 E. coli, 29 Klebsiella spp. Carbapenem resistance was identified in 132 Acinetobacter spp., 27 Pseudomonas spp., 14 K. pneumoniae, 1 E. coli. For Pseudomonas strains, ciprofloxacin and amikacin; for Acinetobacter strains, amikacin and colistin; for Escherichia and Klebsiella strains, amikacin and imipenem were determined as the most effective antibiotics. The most frequently isolated GPBs were 351 (30%) coagulase-negative staphylococci (CNS) (192 S. epidermidis), 111 (9.5%) Enterococcus spp. (67 Enterococcus faecalis), 55 Staphylococcus aureus, respectively. While Methicillin resistance was determined in 7 S. aureus and 191 CNS; vancomycin resistance was detected in 3 Enterococcus faecium strains. The most effective antibiotics against S. aureus and Enterococcus spp. strains were identified as linezolid, vancomycin, and teicoplanin. Conclusion: It will be useful if every center arranges the treatment protocols according to their microorganism distribution and resistance profiles to fight against resistant microorganisms
