Device performance and commercialization of organic solar cells (OSCs) are strongly influenced by the characteristics of the interface layers. Cross-linked polymer interface layers with solvent-resistant properties are very compatible with large-area solution-processing methods of OSCs and may be beneficial to the environmental stability of OSCs due to the viscoelastic and cross-linked characteristics of the cross-linked polymer. In this work, a novel cross-linkable and alcohol-soluble pyridine-incorporated polyfluorene derivative, denoted as PFOPy, is synthesized and used as a cathode interface layer (CIL) in OSCs. For PFOPy, the pendant epoxy group can be effectively cross linked through cationic polymerization under thermal treatment and the pendant pyridine group can offer good alcohol solubility. Optical absorption tests of PFOPy films before/after washing by chloroform demonstrate the excellent solvent-resistance property for the cross-linked PFOPy film. Compared with the typical ZnO CIL, the cross-link very promising CIL in OSCs. Anaemia is associated with a wide range of negative outcomes. Diagnostic blood loss (DBL) may contribute to its occurrence. We aimed to evaluate DBL and its impact on haemoglobin (HGB) concentration and developing anaemia in the intensive care unit (ICU) patients. A study group comprised of 36 adult ICU patients. selleck chemical DBL during 7 consecutive, post-admission days was calculated. Anaemia occurrence was assessed using the WHO thresholds. Data on HGB and haematocrit (HCT) was subjected to analysis. Upon admission, 24 (67%) patients were diagnosed with anaemia, on the eighth day 29 (80%) subjects (with 6 new cases). The median volume of blood collected was 143.15 mL (IQR 121.4-161.65) per week. No differences in DBL were found between the subjects with newly developed anaemia and their counterparts (p=0.4). The median drop of HGB (HbΔ) was 18 gL-1 (IQR 5-28) and the median drop of haematocrit (HtΔ) was 4.55% (IQR 1.1-7.95). There was no correlation between neither HbΔ and DBL (p=0.8) nor HtΔ and DBL (p=0.7). There were also no differences in HbΔ/HtΔ when age, gender or the primary critical illness were taken into account for the analysis (p>0.05 for all). The 7-day fluid balance was associated with haemoglobin drop (R=0.45; p=0.006). Anaemia is frequent in ICU patients. Diagnostic blood loss in our institution is acceptable and seems to protect patients against significant iatrogenic blood loss and subsequent anaemia. Dilutional anaemia may interfere with the results so before-after interventional research is needed to explore this interesting topic. Anaemia is frequent in ICU patients.

Severe asthma has a great impact on quality of life. There is a great heterogeneity of this disease, not only from a clinical point of view, but also from a functional and pathophysiological one. It's really hard to identify specific characteristics that identify this subgroup. Specific registers of SA, both national and international, are really important to describe the epidemiological characteristics of the disease and to analyze the clinical characteristics of the various subgroups of patients. This is an excellent starting point to be able to investigate the characteristics of the disease in detail. Implementing change in healthcare is difficult to accomplish due to the unpredictability associated with challenging the
