Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

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

INTERPRETATION OF CONNECTIVITY METRICS AT DIFFERENT SPATIAL RESOLUTIONS: THE CASE OF CANDARLI BAY-IZMIR, TURKEY

WOS: 000426337900065Landscape metrics play an important role in the quantification of landscape structure and associated processes. But the outputs of landscape structural analysis are affected by the spatial resolution of source data. Whilst the influence of spatial resolution on landscape metrics has received considerable critical attention [e.g. 1, 2], recent studies suggest an association between connectivity metrics and the scale of the source data [3]. In this study, we analysed the structure and distribution of natural and semi-natural vegetation patches in candarli Bay- Izmir using a land cover map with 6 broad land cover types (Forests, Shrub and Herbaceous Vegetation Associations, Agricultural Areas, Artificial Surfaces, Wetlands and Water Bodies) and 9 landscape metrics (FRAGSTATS) across different spatial resolutions (2m, 5m, 10m, 25m, 50m and 100m). Then, we investigated the influence of those landscape metrics on the identification and prioritisation of land cover types in terms of their contribution to physical connectivity. Our results suggested that the results of individual landscape metrics are affected by spatial resolution, but when they interpreted and evaluated altogether, the prioritised land cover types did not change

The efficacy of balneotherapy and physical modalities on the pulmonary system of patients with fibromyalgia

Effects of balneotherapy on Primary Fibromyalgia Syndrome (FMS) have been studied well, except for its effect on the respiratory symptoms of FMS. In this study we allocated 56 patients with FMS into three groups who matched according to age, gender and duration of illness. All three groups received the same three physical therapy modalities (PTM): transcutaneous electrical nerve stimulation (TENS), ultrasound (US) and infrared (IR). The first group received PTM plus balneotherapy (PTM+BT), the second group received PTM alone (PTM), whilst the third group received PTM plus hydrotherapy (PTM+HT). All groups were treated for three weeks and in the same season. All patients were assessed at four time points: (a) at baseline, (b) on the 7th day of therapy, (c) at the end of therapy (after 3 weeks) and (d) at 6 months after the end of therapy. The effectiveness of treatments in all groups were evaluated in three main categories (pain, depressive and respiratory symptoms). Tender point count, total algometric measurements and pain with visual analog scale for pain; Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HDRS) for depression; dyspnea scale, and spirometric measurements for respiratory symptoms; plus quality of life with visual analog scale as a general measurement of effectiveness were taken at all four assessment time points. Both at the end of therapy and at the 6 months follow up significant improvements in dyspnea scale, and spirometric measurements, as well as in other measured parameters were observed in group PTM+BT. All groups achieved significant improvements in BDI and HDRS but scores of PTM and PTM+HT groups had overturned at 6 months follow up. Except second group which receieved PTM alone, pain evaluation assessments were improved at 6 month follow up in PTM+HT and PTM+BT groups. But PTM+BT group had more significant improvements at the end of therapy. PTM group had no significant change for dyspnea scale and spirometric measurements. PTM combined BT and HT groups achieved significant improvements at the end of therapies for dyspnea scale and spirometric measurements, but only PTM+BT group had significant improvements for dyspnea scale and spirometric measurements at six month follow up. The group of PTM+BT was significantly better than other groups. Our results suggest that supplementation of PTM with balneotherapy is effective on the respiratory and other symptoms of FMS and these effects were better than other protocols at 6 month follow up

Effect of a Prolonged Dietary Iron Intake on the Gene Expression and Activity of the Testicular Antioxidant Defense System in Rats

KALIN, Seyda Nur/0000-0002-2594-2489; Budak, Harun/0000-0002-7371-8959; KOCPINAR, ENVER FEHIM/0000-0002-6031-4664; ceylan, hamid/0000-0003-3781-4406; Gonul Baltaci, Nurdan/0000-0001-8104-5988WOS:000525067200016PubMed: 31309445Despite the fact that iron represents a crucial element for the catalysis of many metabolic reactions, its accumulation in the cell leads to the production of reactive oxygen species (ROS), provoking pathological conditions such as cancer, cardiovascular diseases, diabetes, neurodegenerative diseases, and fertility. Thus, ROS are neutralized by the enzymatic antioxidant system for the purpose of protecting cells against any damage. Iron is a potential risk factor for male fertility. However, the mechanism of action of iron on the testicular antioxidant system at the gene and protein levels is not fully understood. Thus, the purpose of the current research was to ensure a better understanding of how the long-term iron treatment influences both gene expression and enzyme activities of the testicular antioxidant system in rat testis. The data of our study showed that a significant dose-dependent increase occurred in the iron level in rat testis. A reduction occurred in reduced glutathione (GSH) levels, which represent a marker of oxidative stress, along with long-term iron overload. The expression and activity of glucose 6-phosphate dehydrogenase (G6pd), glutathione reductase (Gr), glutathione peroxidase (Gpx), and glutathione S-transferases (Gst) were significantly affected by the presence of iron. The findings of the current research demonstrate that the long-term toxic dietary iron overload influences the gene expression and enzyme activity of the testicular antioxidant defense system, but the actual effect occurs at the protein level. This may modify the sperm function and dysfunction of the male reproductive system.Ataturk University Scientific Research Projects Coordination Commission [PRJ2010/277, FAD-2018-6352] Funding Source: Medlin

False-positive 18-fluorodeoxyglucose positron emission tomography–computed tomography (FDG PET/CT) scans mimicking malignancies

Aim 18-Fluorodeoxyglucose (FDG) positron emission tomography–computed tomography (PET/CT) is an imaging modality that is often used to help differentiate benign from malignant pulmonary lesions and it has been shown to be more efficacious than conventional chest computed tomography (CT). However, some benign lesions may also show increased metabolic activity which can lead to false-positive PET findings. We aim to illustrate false positive findings of PET scan that simulate lung cancer in a variety of diseases. Methods Patients referred to Yedikule Chest Diseases and Surgery Teaching and Research Hospital with increased FDG uptake for which histological results were available over a 2-year period (2013-2014) were reviewed. Seven patients with false-positive PET/CT findings were reported in this study. Results The majority of lesions showing increased metabolic activity were due to malignant diseases. However, increased 18 F-FDG uptake was also seen in benign lesions such as active pulmonary inflammation or infection, granulomatous processes and fibrotic lesions. Conclusion. The integration of clinical history, morphologic findings of lesions on the CT component, and metabolic activities of PET/CT scan can help reduce false interpretations. Interventional procedures

Epidemiology and distribution of interstitial lung diseases in Turkey

IntroductionThere is very few data on the epidemiological features of interstitial lung diseases (ILD) in the literature. These studies on this subject suffer from limited number of patients

Serum N-Desmethylcitalopram Concentrations are Associated with the Clinical Response to Citalopram of Patients with Major Depression.

Citalopram (CITA) is a widely used and well-tolerated selective serotonin reuptake inhibitor. The aim of the study was to evaluate the possible influences of serum concentrations of CITA and its major metabolite n-desmethylcitalopram (NDCITA) on the efficacy and tolerability of CITA in patients with major depressive disorder
