    Get PDF
    Young people with ADHD are frequently marginalised, which affects their opportunities to be included within society. This places emphasis on how students are best prepared for becoming part of that society. The present case study investigated the perceptions of a needs-based and individualised support for students with ADHD in the context of a Swiss sociocratic school, from the perspectives of students and social educators. Semi-structured interviews were conducted with students diagnosed with ADHD and a school social educator to explore the influence of the diagnosis on self-perception and self-image, as well as their needs for support from social educators. The results emphasise the significance of belongingness and empowerment for students with ADHD, and how school social educators can act as a link between school and wider society. They demonstrate the importance of individually considering the needs of students with ADHD to provide appropriate support. Recommendations for school social education are made, both for working with students within the school context as well as for preparing them for the time beyond school.  Article visualizations

    Out-of-hospital therapeutic hypothermia in cardiac arrest victims

    Get PDF
    Despite many years of research, outcome after cardiac arrest is dismal. Since 2005, the European Resuscitation Council recommends in its guidelines the use of mild therapeutic hypothermia (32-34°) for 12 to 24 hours in patients successfully resuscitated from cardiac arrest. The benefit of resuscitative mild hypothermia (induced after resuscitation) is well established, while the benefit of preservative mild to moderate hypothermia (induced during cardiac arrest) needs further investigation before recommending it for clinical routine. Animal data and limited human data suggest that early and fast cooling might be essential for the beneficial effect of resuscitative mild hypothermia. Out-of-hospital cooling has been shown to be feasible and safe by means of intravenous infusion with cold fluids or non-invasively with cooling pads. A combination of these cooling methods might further improve cooling efficacy. If out-of-hospital cooling will further improve functional outcome as compared with in-hospital cooling needs to be determined in a prospective, randomised, sufficiently powered clinical trial

    Thromboelastometry for the assessment of coagulation abnormalities in early and established adult sepsis: a prospective cohort study

    INTRODUCTION: The inflammatory response to an invading pathogen in sepsis leads to complex alterations in hemostasis by dysregulation of procoagulant and anticoagulant factors. Recent treatment options to correct these abnormalities in patients with sepsis and organ dysfunction have yielded conflicting results. Using thromboelastometry (ROTEM(R)), we assessed the course of hemostatic alterations in patients with sepsis and related these alterations to the severity of organ dysfunction. METHODS: This prospective cohort study included 30 consecutive critically ill patients with sepsis admitted to a 30-bed multidisciplinary intensive care unit (ICU). Hemostasis was analyzed with routine clotting tests as well as thromboelastometry every 12 hours for the first 48 hours, and at discharge from the ICU. Organ dysfunction was quantified using the Sequential Organ Failure Assessment (SOFA) score. RESULTS: Simplified Acute Physiology Score II and SOFA scores at ICU admission were 52 +/- 15 and 9 +/- 4, respectively. During the ICU stay the clotting time decreased from 65 +/- 8 seconds to 57 +/- 5 seconds (P = 0.021) and clot formation time (CFT) from 97 +/- 63 seconds to 63 +/- 31 seconds (P = 0.017), whereas maximal clot firmness (MCF) increased from 62 +/- 11 mm to 67 +/- 9 mm (P = 0.035). Classification by SOFA score revealed that CFT was slower (P = 0.017) and MCF weaker (P = 0.005) in patients with more severe organ failure (SOFA >or= 10, CFT 125 +/- 76 seconds, and MCF 57 +/- 11 mm) as compared with patients who had lower SOFA scores (SOFA <10, CFT 69 +/- 27, and MCF 68 +/- 8). Along with increasing coagulation factor activity, the initially increased International Normalized Ratio (INR) and prolonged activated partial thromboplastin time (aPTT) corrected over time. CONCLUSIONS: Key variables of ROTEM(R) remained within the reference ranges during the phase of critical illness in this cohort of patients with severe sepsis and septic shock without bleeding complications. Improved organ dysfunction upon discharge from the ICU was associated with shortened coagulation time, accelerated clot formation, and increased firmness of the formed blood clot when compared with values on admission. With increased severity of illness, changes of ROTEM(R) variables were more pronounced

    Influence of Interferon-Alpha Combined with Chemo (Radio) Therapy on Immunological Parameters in Pancreatic Adenocarcinoma

    Prognosis of patients with carcinoma of the exocrine pancreas is particularly poor. A combination of chemotherapy with immunotherapy could be an option for treatment of pancreatic cancer. The aim of this study was to perform an immunomonitoring of 17 patients with pancreatic cancer from the CapRI-2 study, and tumor-bearing mice treated with combination of chemo (radio) therapies with interferon-2. Low doses of interferon-2 led to a decrease in total leukocyte and an increase in monocyte counts. Furthermore, we observed a positive effect of interferon-2 therapy on the dendritic cells and NK (natural killer) cell activation immediately after the first injection. In addition, we recorded an increased amount of interferon- and IL-10 in the serum following the interferon-2 therapy. These data clearly demonstrate that pancreatic carcinoma patients also show an immunomodulatory response to interferon-2 therapy. Analysis of immunosuppressive cells in the Panc02 orthotopic mouse model of pancreatic cancer revealed an accumulation of the myeloid-derived suppressor cells in spleens and tumors of the mice treated with interferon-2 and 5-fluorouracil. The direct effect of the drugs on myeloid-derived suppressor cells was also registered in vitro. These data expose the importance of immunosuppressive mechanisms induced by combined chemo-immunotherapy

    Interferon-alpha Up-Regulates the Expression of PD-L1 Molecules on Immune Cells Through STAT3 and p38 Signaling

    Interferon-alpha (IFN alpha) has one of the longest histories of use amongst cytokines in clinical oncology and has been applied for the treatment of many types of cancers. Due to its immune-activating properties, IFN alpha is also an attractive candidate for combinatory anti-cancer therapies. Despite its extensive use in animal tumor models as well as in several clinical trials, the different mechanisms underlying patient responses and affecting desirable clinical benefits are still under investigation. Here we show that in addition to its immune-activating properties, IFN alpha induces the expression of a key negative regulator, immunosuppressive PD-L1 molecule, in the majority of the specific immune cell populations, particularly in the dendritic cells (DC). DC can modulate immune responses by a variety of mechanisms, including expression of T-cell regulatory molecules and cytokines. Our results showed that treatment of DC with IFN alpha-2b led to pronounced up-regulation of surface expression of PD-L1 molecules, increased IL-6 and decreased IL-12 production. Moreover, we present evidence that IFN alpha-treated DC exhibited a reduced capacity to stimulate interferon-gamma production in T cells compared to control DC. This T-cell response after treatment of DC with IFN alpha was recovered by a pre-treatment with an anti-PD-L1 blocking antibody. Further analyses revealed that IFN a regulated PD-L1 expression through the STAT3 and p38 signaling pathways, since blocking of STAT3 and p38 activation with specific inhibitors prevented PD-L1 up-regulation. Our findings underline the important roles of p38 and STAT3 in the regulation of PD-L1 expression and prove that IFN alpha induces STAT3/p38-mediated expression of PD-L1 and thereby a reduced stimulatory ability of DC. The augmentation of PD-L1 expression in immune cells through IFN alpha treatment should be considered by use of IFN alpha in an anti-cancer therapy

Our results showed that treatment of DC with IFNα-2b led to pronounced up-regulation of surface expression of PD-L1 molecules, increased IL-6 and decreased IL-12 production. Moreover, we present evidence that IFNα-treated DC exhibited a reduced capacity to stimulate interferon-γ production in T cells compared to control DC. This T-cell response after treatment of DC with IFNα was recovered by a pre-treatment with an anti-PD-L1 blocking antibody.

    The continuation of utilizing fossil fuels as cooking energy sources in rural communities in the Philippines causes more citizens to be at risk of developing numerous health illnesses. This study aimed to propose a potential solution to this problem by innovating a self-agitating anaerobic batch digester, promoting biogas production of cattle manure co-digested with Lemna minor. Two anaerobic batch digester designs, one with baffles and one without, were observed within 22 days to determine the impact of the anaerobic digester design on mixing and biogas production yield. The study contained two pairs of anaerobic batch digesters, the initial and improved digester. The water displacement method was used to measure the biogas yield from the initial and improved digesters. The results of this study on the quantity of biogas produced between the initial experimental designs measured every six days and revised experimental designs measured every four days concluded that anaerobic batch digester designs with baffles produced a superior amount of biogas with 5468.88 cm³ more yield than the digester without baffles. Utilizing an Independent Sample T-test, the difference in biogas production is considered significant, (p = .174). Similar studies in the future are encouraged to explore variations in the anaerobic digester design outside of the placement of baffles, including factors such as the materials used and the period of observation due to the limitations of this study
