The applicability of wildlife value orientations scales to a Muslim student sample in Malaysia

This article addresses the applicability of quantitative wildlife value orientation scales in Muslim students in Malaysia. As Malaysian culture is deeply influenced by Islam ideology, this article presents a case for addressing the cross-cultural applicability of the scales. The current wildlife value orientation scales were reliable—all Cronbach’s alphas ≥ .65—and had predictive validity—8 to 14% of variance of acceptability of lethal control was explained. Yet, both reliability and predictive validity were of lesser magnitude than figures in previous Western studies. Especially the hunting beliefs scale did not reflect basic thinking about wildlife in our sample, and our data suggest two different hunting dimensions—consequences of hunting for wildlife and human opportunities for hunting. For future cross-cultural comparisons of wildlife value orientations, amendment of the scales to better reflect salient beliefs in non-Western nations is recommended

Beyond biophobia: positive appraisal of bats among German residents during the COVID-19 pandemic - with consequences for conservation intentions

Bats are often considered to be objects of biophobia, i.e., the tendency to respond with a negative emotion, such as fear or disgust, especially during the COVID-19 pandemic. However, existing studies have rarely compared both positive and negative emotions towards bats, leading to a potential negativity bias. This is crucial given the importance of emotions to bat-related human behaviours, such as in bat conservation-related actions. Via two online surveys conducted among German residents, we aimed to (i) assess positive and negative emotions towards bats, (ii) examine emotional shifts during the pandemic and (iii) explore how emotions, along with socio-demographics, predict the intent to perform bat-conservation actions. The first survey was undertaken ten months after the official declaration of the COVID-19 pandemic (December 2020 - January 2021), when bats gained societal attention due to speculation about the origin of the SARS-CoV-2 virus, and the second one ran twelve months later (January 2022). Overall, respondents held higher positive emotions than negative ones towards bats in both surveys, with no significant emotional shift observed. Positive emotions positively correlated with intentions to perform bat-conservation actions, while negative emotions showed no such relationship. Although our findings might be context-specific to populations in Germany or Europe, given European-Union legislation protecting bats and their habitats, they highlight the nuanced and complicated emotions that can be associated with certain species. Understanding these emotions can guide targeted conservation strategies and public outreach. Our results caution against overly generalising discussions of biophobia in conservation

Hemolysis is an inevitable side effect of cardiopulmonary bypass resulting in increased plasma free hemoglobin that may impair tissue perfusion by scavenging nitric oxide. Acute kidney injury after on-pump cardiovascular surgery arises from a number of causes and severely affects patient morbidity and mortality. Here, we studied the effect of acute hemolysis on renal injury in 35 patients undergoing on-pump surgical repair of thoracic and thoracoabdominal aortic aneurysms of whom 19 experienced acute kidney injury. During surgery, plasma free hemoglobin increased, as did urinary excretion of the tubular injury marker N-acetyl-β-D-glucosaminidase, in patients with and without acute kidney injury, reaching peak levels at 2 h and 15 min, respectively, after reperfusion. Furthermore, plasma free hemoglobin was independently and significantly correlated with the urine biomarker, which, in turn, was independently and significantly associated with the later postoperative increase in serum creatinine. Importantly, peak plasma free hemoglobin and urine N-acetyl-β-D-glucosaminidase concentrations had significant predictive value for postoperative acute kidney injury. Thus, we found an association between increased plasma free hemoglobin and renal injury casting new light on the pathophysiology of acute kidney injury. Therefore, free hemoglobin is a new therapeutic target to improve clinical outcome after on-pump cardiovascular surgery

Histoire des syndicats de fonctionnaires et du mouvement social en Seine Maritime de 1944 à 1981

In 1944, the National Council of Resistance decides to rebuild a welfare state, in continuation of the Popular Front, that the second World War stops it. The trade unions reunified, in CGT (except CFTC) decide to sustain this program. The trade unions of civil servants from Seine-Maritime organize themselves to take part in this rebuild that they waited for it. What are their demands ? On What do they lean themselves to put them before ? What are their values for which they fight? Do they wait all from the state ? What is their idea of this welfare state ? At least, what means do they use to fight for it and bring it to progress ? Getting the recognition of their freedom union laws, which includes right striking, they agree civil servant status which turn out very protective against their adminstration and its hierarchy. They get too the management of Health Security by their mutual insurances which lead them, in Seine-Maritme, to build a powerful departemental mutual insurance. However, the division of world in two blocks, one liberal and one communist, goes through these trade unions and leads to the break away of 1947 That does not prevent the participation to strikes of 1953 wich they are be able to save their retirement. If they sustain general De Gaulle in his decolonization policy and against seditious generals, they clash him on his institutional, économic and social policy. The strike of 1968 is the culmination of it, throuhgout adjournements. But in order to restore the welfare state that they hope, they must sustain lefts’ candidate, François Mitterrand, in their electoral compaigns of 1974 and 1981, who wins in this last year, in spite of their differences and thanks to the Will of unity of their activists.En 1944, le Conseil national de la Résistance décide de reconstruire un Etat social dans la continuité du Front populaire, avant que le second conflit ne l’interrompe. Les syndicats ouvriers réunifiés dans la CGT (sauf la CFTC) décident de soutenir ce programme. Les syndicats de fonctionnaires de Seine-Maritime s’organisent pour participer à cette reconstruction qu’ils attendaient. Quels sont leurs revendications ? Sur quoi s’appuient-ils pour les mettre en avant ? Quels sont les valeurs qu’ils défendent ? Attendent-ils tout de l’Etat social ? Quelle est leur conception de cet Etat social ? Enfin, quels moyens utilisent-ils pour le défendre et le faire progresser ? Obtenant la reconnaissance de leur liberté syndicale qui comprend le droit de grève, ils acceptent un statut qui se révèle fort protecteur vis-à-vis de l’administration et de sa hiérarchie. Ils obtiennent aussi la gestion de la Sécurité sociale par leurs mutuelles qui les entraînent, en Seine-Maritime, à construire une mutualité départementale unifiée et puissante. Toutefois, la division du monde en deux blocs, un libéral et un communiste, traverse ces syndicats et aboutit à la scission de 1947. Cela n’empêche pas la participation aux grèves de 1953 qui leur permet de sauver leur retraite. S’ils soutiennent le général de Gaulle (1890-1970) dans sa politique de décolonisation et contre les généraux factieux, ils l’affrontent sur sa politique institutionnelle, économique et sociale. La grève de 1968 en est l’aboutissement, par-delà les remises en cause. Mais pour rétablir l’Etat social qu’ils souhaitent, il leur faut soutenir les campagnes électorales de 1974 et 1981 du candidat de la gauche, François Mitterrand (1916-1996), qui l’emporte en 1981, en dépit de leurs divergences et grâce à la volonté unitaire de leurs militants

IVIg-induced plasmablasts in patients with Guillain-Barré syndrome

Objective: The Guillain–Barré syndrome (GBS) is an acute, immune-mediated disease of peripheral nerves. Plasmablasts and plasma cells play a central role in GBS by producing neurotoxic antibodies. The standard treatment for GBS is high-dose intravenous immunoglobulins (IVIg), however the working mechanism is unknown and the response to treatment is highly variable. We aimed to determine whether IVIg changes the frequency of B-cell subsets in patients with GBS. Methods: Peripheral blood mononuclear cells were isolated from 67 patients with GBS before and/or 1, 2, 4, and 12 weeks after treatment with high-dose IVIg. B-cell subset frequencies were determined by flow cytometry and related to serum immunoglobulin levels. Immunoglobulin transcripts before and after IVIg treatment were examined by next-generation sequencing. Antiglycolipid antibodies were determined by ELISA. Results: Patients treated with IVIg demonstrated a strong increase in plasmablasts, which peaked 1 week after treatment. Flow cytometry identified a relative increase in IgG2 plasmablasts posttreatment. Within IGG sequences, dominant clones were identified which were also IGG2 and had different immunoglobulin sequences compared to pretreatment samples. High plasmablast frequencies after treatment correlated with an increase in serum IgG and IgM, suggesting endogenous production. Patients with a high number of plasmablasts started to improve earlier (P = 0.015) and were treated with a higher dose of IVIg. Interpretation: High-dose IVIg treatment alters the distribution of B-cell subsets in the peripheral blood of GBS patients, suggesting de novo (oligo-)clonal B-cell activation. Very high numbers of plasmablasts after IVIg therapy may be a potential biomarker for fast clinical recovery

EZH2 and BMI1 inversely correlate with prognosis and TP53 mutation in breast cancer

Introduction PolycombGroup (PcG) proteins maintain gene repression through histone modifications and have been implicated in stem cell regulation and cancer. EZH2 is part of Polycomb Repressive Complex 2 (PRC2) and trimethylates H3K27. This histone mark recruits the BMI1-containing PRC1 that silences the genes marked by PRC2. Based on their role in stem cells, EZH2 and BMI1 have been predicted to contribute to a poor outcome for cancer patients. Methods We have analysed the expression of EZH2 and BMI1 in a well-characterised dataset of 295 human breast cancer samples. Results Interestingly, although EZH2 overexpression correlates with a poor prognosis in breast cancer, BMI1 overexpression correlates with a good outcome. Although this may reflect transformation of different cell types, we also observed a functional difference. The PcG-target genes INK4A and ARF are not expressed in tumours with high BMI1, but they are expressed in tumours with EZH2 overexpression. ARF expression results in tumour protein P53 (TP53) activation, and we found a significantly higher proportion of TP53 mutations in tumours with high EZH2. This may explain why tumours with high EZH2 respond poorly to therapy, in contrast to tumours with high BMI1. Conclusions Overall, our data highlight that whereas EZH2 and BMI1 may function in a 'linear' pathway in normal development, their overexpression has different functional consequences for breast tumourigenesi

Immediate versus postponed intervention for infected necrotizing pancreatitis

BACKGROUND Infected necrotizing pancreatitis is a potentially lethal disease that is treated with the use of a step-up approach, with catheter drainage often delayed until the infected necrosis is encapsulated. Whether outcomes could be improved by earlier catheter drainage is unknown. METHODS We conducted a multicenter, randomized superiority trial involving patients with infected necrotizing pancreatitis, in which we compared immediate drainage within 24 hours after randomization once infected necrosis was diagnosed with drainage that was postponed until the stage of walled-off necrosis was reached. The primary end point was the score on the Comprehensive Complication Index, which incorporates all complications over the course of 6 months of follow-up. RESULTS A total of 104 patients were randomly assigned to immediate drainage (55 patients) or postponed drainage (49 patients). The mean score on the Comprehensive Complication Index (scores range from 0 to 100, with higher scores indicating more severe complications) was 57 in the immediate-drainage group and 58 in the postponed-drainage group (mean difference, −1; 95% confidence interval [CI], −12 to 10; P=0.90). Mortality was 13% in the immediate-drainage group and 10% in the postponed-drainage group (relative risk, 1.25; 95% CI, 0.42 to 3.68). The mean number of interventions (catheter drainage and necrosectomy) was 4.4 in the immediate-drainage group and 2.6 in the postponed-drainage group (mean difference, 1.8; 95% CI, 0.6 to 3.0). In the postponed-drainage group, 19 patients (39%) were treated conservatively with antibiotics and did not require drainage; 17 of these patients survived. The incidence of adverse events was similar in the two groups. CONCLUSIONS This trial did not show the superiority of immediate drainage over postponed drainage with regard to complications in patients with infected necrotizing pancreatitis. Patients randomly assigned to the postponed-drainage strategy received fewer invasive interventions

Incidence of Interval Colorectal Cancer After Negative Results From First-Round Fecal Immunochemical Screening Tests, by Cutoff Value and Participant Sex and Age

Background & Aims: We evaluated the incidence of interval cancers between the first and second rounds of colorectal cancer (CRC) screening with the FOB-Gold fecal immunochemical test (FIT), and the effects of different cutoff values and patient sex and age. Methods: We collected data from participants in a population-based

B-cell targeting with anti-CD38 daratumumab:implications for differentiation and memory responses

B cell–targeted therapies, such as CD20-targeting mAbs, deplete B cells but do not target the autoantibody-producing plasma cells (PCs). PC-targeting therapies such as daratumumab (anti-CD38) form an attractive approach to treat PC-mediated diseases. CD38 possesses enzymatic and receptor capabilities, which may impact a range of cellular processes including proliferation and differentiation. However, very little is known whether and how CD38 targeting affects B-cell differentiation, in particular for humans beyond cancer settings. Using in-depth in vitro B-cell differentiation assays and signaling pathway analysis, we show that CD38 targeting with daratumumab demonstrated a significant decrease in proliferation, differentiation, and IgG production upon T cell–dependent B-cell stimulation. We found no effect on T-cell activation or proliferation. Furthermore, we demonstrate that daratumumab attenuated the activation of NF-κB in B cells and the transcription of NF-κB–targeted genes. When culturing sorted B-cell subsets with daratumumab, the switched memory B-cell subset was primarily affected. Overall, these in vitro data elucidate novel non-depleting mechanisms by which daratumumab can disturb humoral immune responses. Affecting memory B cells, daratumumab may be used as a therapeutic approach in B cell–mediated diseases other than the currently targeted malignancies.</p
