No full textAn old unknown: 40 years of crayfish plague monitoring in Switzerland, the water tower of Europe.
No full textThe oomycete Aphanomyces astaci is the causative agent of crayfish plague, a disease threatening susceptible freshwater crayfish species in Europe. To detect its spatiotemporal occurrence in Switzerland, we reviewed (1) the literature regarding occurrence of crayfish plague and North American crayfish carrier species and (2) the necropsy report archive of the Institute for Fish and Wildlife Health (FIWI) from 1968 to 2020. In the past, crayfish plague was diagnosed through several methods: conventional PCR, culture, and histology. When available, we re-evaluated archived Bouin's or formalin-fixed, paraffin-embedded samples collected during necropsies (1991-2020) with a recently published quantitative PCR. Literature research revealed putative reports of crayfish plague in Switzerland between the 1870s and 1910s and the first occurrence of three North American crayfish species between the late 1970s and 1990s. Finally, 54 (28.1%) cases were classified as positive and 9 (4.7%) cases as suspicious. The total number of positive cases increased by 14 (14.7%) after re-evaluation of samples. The earliest diagnosis of crayfish plague was performed in 1980 and the earliest biomolecular confirmation of A. astaci DNA dated 1991. Between 1980-1990, 1991-2000 and 2001-2010 crayfish plague spread from one to two and finally three catchment basins, respectively. Similar to other European countries, crayfish plague has occurred in Switzerland in two waves: the first at the end of the 19th and the second at the end of the 20th century in association with the first occurrence of North American crayfish species. The spread from one catchment basin to another suggests a human-mediated pathogen dispersal
Anticoagulation reversal (vitamin K, prothrombin complex concentrates, idarucizumab, andexanet-α, protamine).
Full text linkBleeding events are common in patients prescribed anticoagulants and can have devastating consequences. Several specific and nonspecific agents have been developed to reverse the effects of anticoagulant drugs or toxins. Vitamin K, as the oldest of these antidotes, specifically counteracts the effects of pharmaceuticals and rodenticides designed to deplete stores of vitamin K-dependent factors. In cases of life-threatening bleeding, the addition of prothrombin complex concentrates (PCCs) allows for the immediate replacement of coagulation factors. While the use of PCCs has been extended to the non-specific reversal of the effects of newer direct oral anticoagulants, the specific agents idarucizumab, targeting dabigatran and andexanet-α, binding factor Xa inhibitors, have recently been developed and are being preferentially recommended by most guidelines. However, despite having rapid effects on correcting coagulopathy, there is to date a lack of robust evidence establishing the clear superiority of direct oral anticoagulant-specific reversal agents over PCCs in terms of haemostatic efficacy, safety or mortality. For andexanet-α, a potential signal of increased thromboembolic risks, comparatively high costs and low availability might also limit its use, even though emerging evidence appears to bolster its role in intracranial haemorrhage. Protamine is the specific agent for the reversal of unfractionated heparin anticoagulation used mainly in cardiovascular surgery. It is much less effective for low molecular weight heparin fragments and is usually reserved for cases with life-threatening bleeding
Microsurgical Repair of Ventral Cerebrospinal Fluid Leaks in Spontaneous Intracranial Hypotension: Efficacy and Safety of Patch-Sealing Versus Suturing.
Full text linkBACKGROUND AND OBJECTIVES
In patients with spontaneous intracranial hypotension (SIH), microsurgical repair is recommended in Type 1 (ventral) dural leaks, when conservative measures fail. However, there is lacking consensus on the optimal surgical technique for permanent and safe closure of ventral leaks.
METHODS
We performed a retrospective analysis of surgically treated SIH patients with Type 1 leaks at our institution between 2013 and 2023. Patients were analyzed according to the type of surgical technique: (1) Microsurgical suture vs (2) extradural and intradural patching (sealing technique). End points were resolution of spinal longitudinal epidural cerebrospinal fluid collection (SLEC), change in brain SIH-Score (Bern-Score), headache resolution after 3 months, surgery time, complications, and reoperation rates.
RESULTS
In total, 85 (66% women) patients with consecutive SIH (mean age 47 ± 11 years) underwent transdural microsurgical repair. The leak was sutured in 53 (62%) patients (suture group) and patch-sealed in 32 (38%) patients (sealing group). We found no significant difference in the rates of residual SLEC and resolution of headache between suture and sealing groups (13% vs 22%, P = .238 and 89% vs 94%, P = .508). No changes were found in the postoperative Bern-Score between suture and sealing groups (1.4 [±1.6] vs 1.7 [±2.1] P = 1). Mean surgery time was significantly shorter in the sealing group than in the suture group (139 ± 48 vs 169 ± 51 minutes; P = .007). Ten patients of the suture and 3 of the sealing group had a complication (23% vs 9%, P = .212), whereas 6 patients of the suture and 2 patients of the sealing group required reoperation (11% vs 6%, P = .438).
CONCLUSION
Microsurgical suturing and patch-sealing of ventral dural leaks in patients with SIH are equally effective. Sealing alone is a significantly faster technique, requiring less spinal cord manipulation and may therefore minimize the risk of surgical complications
Sex- and age-specific reference intervals of 16 steroid metabolites quantified simultaneously by LC-MS/MS in sera from 2458 healthy subjects aged 0 to 77 years.
No full textBACKGROUND
Reference intervals covering the whole life span for all the metabolites in the steroid hormone biosynthesis quantified by sensitive and robust analytical methods are sparse or not existing.
OBJECTIVE
To develop a state-of-the-art LC-MS/MS method for simultaneous quantification of multiple steroid metabolites and to establish detailed sex- and age-specific reference intervals for 16 steroid metabolites.
MATERIALS AND METHOD
An isotope diluted LC-MS/MS method was developed for simultaneous quantitation of 16 steroid hormones. Serum samples from cross-sectional cohorts of healthy infants, children, adolescents, and adults aged 0.17 months to 77 years (n = 2458) were analysed.
RESULTS
With this novel, specific, and sensitive LC-MS/MS method, it was possible to quantify progesterone, 17-hydroxypregnenolone, 17-hydroxyprogesterone, dehydroepiandrosterone sulfate, androstenedione, testosterone, dihydrotestosterone, 11-deoxycorticosterone, corticosterone, 11-deoxycortisol, cortisol, and cortisone in ≥90 % of the samples, while estrone sulfate, aldosterone and dehydroepiandrosterone were quantified in 77 %, 75 % and 60 % of the samples, respectively. 21-deoxycortisol was only detectable in 2.5 % of samples from healthy subjects. Sex- and age-dependent fluctuations observed in minipuberty, puberty and adulthood including the menopausal transition were modelled. This enabled us to establish valid reference intervals from birth to late adult life for both males and females.
CONCLUSION
Detailed sex- and age-specific reference intervals of multiple, simultaneously quantified steroid metabolites by a novel and specific LC-MS/MS method provides a valuable tool for clinical practice and for future research
Longitudinal Outcomes of Thoracic Endovascular Aortic Repair for Ruptured Thoracic Aortic Aneurysms.
No full textOBJECTIVES
Limited data exist on long-term mortality and reintervention rates of emergent thoracic endovascular aortic repair (TEVAR) for ruptured thoracic aortic aneurysm (rTAA). This study aimed to characterize the long-term outcomes of emergent TEVAR for rTAA.
METHODS
This study reviewed all TEVARs for emergent rTAA and elective intact thoracic aortic aneurysms (iTAA) from August 2005 to March 2022 at a large academic medical center. Outcomes, including overall survival and reinterventions, were considered over eight years.
RESULTS
Of 321 patients, 65 received TEVAR for rTAA (34 hemodynamically stable) and 256 for iTAA. Respective mean (SD) ages were 74.4 (11.9) and 74.7 (9.1) years. Median follow-up was 5.1 years. rTAA patients had lower 30-day survival (69.2% vs 96.9%, P < .001) and higher rates of stroke, pneumonia, and prolonged ventilation (all P ≤ .01). Survival was significantly worse for rTAA at 1 year (46% vs 86%), 5 years (27% vs 48%), and 8 years (20% vs 32%; all P < .001). For patients surviving at least 90 days, the long-term survival difference narrowed to statistical insignificance. Ruptured aneurysms required more reinterventions within 30 days, but comparable long-term reintervention rates. Indications for reintervention were similar, with type I endoleak as the leading cause. Long-term survival for hemodynamically stable rTAA patients did not differ significantly from iTAA patients (49% vs 48% at 5 years).
CONCLUSIONS
Short-to-medium-term outcomes are worse for ruptured aneurysms. However, long-term survival of hemodynamically stable rTAA patients and rTAA patients who survive the first 90 days are comparable to iTAA patients
The european registry for patients with mechanical circulatory support (EUROMACS): fourth paediatric EUROMACS (Paedi-EUROMACS) report.
No full textOBJECTIVES
The use of ventricular assist devices in children is increasing. However, absolute numbers in individual centers and countries remain small. Collaborative efforts such as the Paedi-EUROMACS are therefore essential in order to combine international experience with paediatric ventricular assist devices. In this paper, the results from the fourth Paedi-EUROMACS report are presented.
METHODS
All paediatric (<19 years) patients supported by a ventricular assist device from the EUROMACS database were included. Patients are stratified into a congenital heart disease group and a group with a non-congenital aetiology. Endpoints included mortality, transplantation and recovery. Cox proportional hazard models were used to explore associated factors for mortality, cerebrovascular accident, and pump thrombosis.
RESULTS
590 primary implantations were included. The congenital group was significantly younger (2.5 versus 8.0 years respectively, p < 0.001) and were more commonly supported by a pulsatile flow device (73.5% vs 59.9%, p < 0.001). Mortality was significantly higher in the congenital group (30.8 vs 20.4%; p = 0.009) than in the non-congenital group. However, in multivariable analyses, congenital heart disease was not significantly associated with mortality (HR 1.285, CI 0.8111-2.036, p = 0.740). Pump thrombosis was the most frequently reported adverse event (377 events in 132 patients; 0.925 events per patient-year) and was significantly associated with BSA (HR 0.524 CI 0.333-0.823, p = 0.005), congenital heart disease (HR 1.641 CI 1.054-2.555, p = 0.028) and pulsatile flow support (HR 2.345 CI 1.406-3.910, p = 0.001) in multivariable analyses.
CONCLUSIONS
This fourth Paedi-EUROMACS report highlights the increasing use of paediatric ventricular assist devices. The patient populations with congenital and non-congenital aetiology exhibit distinct characteristics and clinical outcomes
The impact of the COVID-19 pandemic on administrative eating disorder prevalence in the outpatient sector and on severity of anorexia nervosa.
Full text linkThe COVID-19 pandemic appears to have had a considerable impact on the mental health of children and adolescents, particularly regarding eating disorders. However, it remains unclear whether the pandemic affected only the frequency or also the severity of eating disorders. We examined potential pandemic-related changes in the administrative prevalence of eating disorders in the outpatient sector compared with other mental disorders using German statutory health insurance data for the age group 10 to 16 years. We also examined disorder severity of anorexia nervosa using data from the multicenter German Registry of Children and Adolescents with Anorexia Nervosa in the same age group. Our results showed a marked increase in the administrative prevalence of eating disorders (based on documented diagnoses) in the outpatient sector among girls but not among boys. A similar pattern was found for internalizing disorders, whereas the administrative prevalences of externalizing disorders decreased. Regarding the severity of anorexia nervosa among inpatients, we found no pandemic-related changes in body mass index standard deviation score at admission, body weight loss before admission, psychiatric comorbidities and psychopharmacological medication. Given the administrative prevalence increase in the outpatient sector, the lack of impact of the pandemic on the inpatient sector may also be partly due to a shift in healthcare utilization towards outpatient services during the pandemic. Thus, the higher number of children and adolescents requiring specialized and timely outpatient care may be a major concern under pandemic conditions
Disentangling the effects of self-control and the use of tobacco and cannabis on violence perpetration from childhood to early adulthood.
Full text linkAssociations among self-control, substance use (e.g., tobacco and cannabis use), and violence perpetration have been documented during the adolescent years, but the direction of these associations is not well understood. Using five assessments (covering 9 years) from a prospective-longitudinal study, we examined self-control as a precursor and subsequent mechanism of associations between adolescent substance use and physical violence perpetration. Data came from a large, ethnically diverse sample (n = 1,056). Youth reported their self-control at ages 11, 13, 15, 17, and 20; and their tobacco and cannabis use, and physical violence perpetration at ages 13, 15, 17, and 20. Cross-lagged panel analyses examined associations between these constructs over time. More self-control in late childhood and early adolescence was associated with less future tobacco and cannabis use and physical violence perpetration. Tobacco use was partially associated with more physical violence over time; these associations were not mediated by self-control. Tobacco use in early adolescence was associated with future cannabis use; during late adolescence, tobacco and cannabis use were reciprocally associated over time. Cannabis use was not associated with future physical violence perpetration. Early adolescent self-control plays an important role in later substance use and violence perpetration, and tobacco use has unique links with both later cannabis use and violence perpetration. Supporting the capacities for self-control in late childhood and early adolescence and preventing the initiation and use of entry-level substances could play an important role in preventing both substance use and violence perpetration and their many costs to society
‘It is important artists react to the world in which we all live’: An interview with Philippe Manoury on Lab.Oratorium
No full textLab.Oratorium (2019) is the concluding part of Philippe Manoury’s Köln Trilogy. It follows In situ (2013) and Ring (2016) in exploring the spoken voice as a musical element, the wider pos- sibilities of the orchestra, and the use of sound spatialization and live electronics. Lab.Oratorium is also a work deeply rooted in the present. In this interview, Philippe Manoury discusses the pol- itical and poetic significance of this work, conceived as an artistic response to Europe’s responsibility in the tragic situation of migrants around the Mediterranean. He also develops his thoughts on musical form, spatialization and creative process in music
