RESUMO

This paper examines the Multistakeholder initiative (MSI) "German Initiative on Sustainable Cocoa (GISCO)". MSIs represent arenas in which heterogeneous actors from governments, businesses and civil society come together to achieve sustainability goals that they cannot achieve otherwise. The self-defined goals of GISCO are first, to improve the living conditions of cocoa farmers and their families; second, to conserve and protect natural resources and biodiversity; and third, to increase the share of sustainably produced cocoa. Although all stakeholder groups share these goals, they have different agendas and conflicting interests. Despite numerous case studies, no theoretical basis has been established on the functioning and success of negotiations in MSIs. Therefore, the question arises as to how the governance of an MSI can be captured empirically to explain (un)achieved outcomes of the collaboration. The contribution of this paper is the development of a theoretical framework and its application to the case study. Minutes of 84 meetings and 18 qualitative expert interviews were analyzed by social network analysis and qualitative content analysis using MaxQDA to identify (a) influential actors, (b) collaboration structures and (c) processes as well as (d) topics discussed to explain (not) achieved outcomes regarding the self-defined goals. The results provide detailed insight into the governance of an MSI. The MSI helps members to extend their individual networks and to learn from each other, but quickly reaches its limits in achieving the self-imposed common goals. One reason for this is the lack of representation of actors from the Global South, despite addressing environmental and living conditions there in two out of the three GISCO goals. Furthermore, it is shown that the structures and processes of decision-making within the MSI are designed in such a way that a lack of hierarchical directives, sanctions and other decision-making mechanisms makes negotiation-based compromises difficult. Consequently, the power of each stakeholder group to use their veto right to delay or prevent the changes required to achieve common goals cannot be overcome.

RESUMO

Abstract: Most process mining techniques are primarily automated, meaning that process analysts input information and receive output. As a result, process mining techniques function like black boxes with limited interaction options for analysts, such as simple sliders for filtering infrequent behavior. Recent research tries to break these black boxes by allowing process analysts to provide domain knowledge and guidance to process mining techniques, i.e., hybrid intelligence. Especially, in process discovery-a critical type of process mining-interactive approaches emerged. However, little research has investigated the practical application of such interactive approaches. This paper presents a case study focusing on using incremental and interactive process discovery techniques in the healthcare domain. Though healthcare presents unique challenges, such as high process execution variability and poor data quality, our case study demonstrates that an interactive process mining approach can effectively address these challenges.

RESUMO

AIMS AND METHODS: We evaluated an ultrasound score from 0 to 32 points in eight pulmonary regions to monitor critically ill COVID-19 patients. The score was correlated to surrogate parameters of disease severity, i.e., the oxygenation index, respiratory support, mortality, plasma interleukin-6, and WHO and ARDS classifications. RESULTS: A total of 27 patients were repeatedly examined, and 71 examinations were evaluated. Patients with severe COVID-19 scored higher (median 17) than those with moderate disease (median 11, p < 0.01). The score did not differentiate between stages of ARDS as defined by the Berlin criteria (p = 0.1) but could discern ARDS according to the revised ESICM definition (p = 0.002). Non-survivors had higher ultrasound scores than survivors (median 18.5 vs. 14, p = 0.04). The score correlated to the oxygenation index (ρ = -0.56, p = 0.03), and changes in the score between examinations correlated to changes in oxygenation (ρ = -0.41, p = 0.16). The correlation between the score and interleukin-6 was ρ = 0.35 (p < 0.001). The interrater reliability for the score was ICC = 0.87 (p < 0.001). CONCLUSIONS: The ultrasound score is a reliable tool that might help monitor disease severity and may help stratify the risk of mortality.

RESUMO

The European Tertiary Education Register (ETER) is the reference dataset on European Higher Education Institutions (HEIs). ETER provides data on nearly 3,500 HEIs in about 40 European countries, including descriptive information, geographical information, students and graduates (with various breakdowns), revenues and expenditures, personnel, and research activities; as of March 2023, data cover the years from 2011-2020. ETER complies with OECD-UNESCO-EUROSTAT standards for educational statistics; most data are collected from National Statistical Authorities (NSAs) or ministries of participating countries and are subject to extensive checks and harmonization. The development of ETER has been funded by the European Commission and is part of the current efforts to establish a European Higher Education Sector Observatory; it is closely connected to the establishment of a broader data infrastructure in the field of science and innovation studies (RISIS). The ETER dataset is widely used in the scholarly literature on higher education and science policy, as well as for policy reports and analyses.

RESUMO

Introduction: Dermatitis herpetiformis (DH) is a rare autoimmune, polymorphous blistering disorder, characterized by severe itch or burning sensation, which represents the cutaneous manifestation of celiac disease (CD). The current estimation of DH versus CD is around 1:8 and the affected individuals have a genetic predisposition. Pathogenetically, IgA autoantibodies against the epidermal transglutaminase, an essential constituent of the epidermis, cause DH and are reported to develop through cross-reaction with the tissue transglutaminase, with IgA auto-antibodies causing CD. Immunofluorescence techniques allow for a rapid diagnostics of the disease using patient sera. Evaluation of IgA endomysial deposition with indirect immunofluorescence on monkey oesophagus is highly specific, but moderately sensitive, with some operator-dependent variability. Recently, indirect immunofluorescence with monkey liver as a substrate has been proposed as an alternative, well-functioning diagnostic approach with higher sensitivity in CD. Methods: The objective of our study was to evaluate whether monkey oesophagus or liver tissue shows advantage for diagnostics in patients with DH, compared to CD. To that end, sera of 103 patients with DH (n=16), CD (n=67) and 20 controls ere compared by 4 blinded experienced raters. Results: For DH, we found a sensitivity of 94.2% for monkey liver (ML) compared to 96.2% in monkey oesophagus (ME), while specificity in ML was superior (91.6% versus 75%) to ME. In CD, ML had a sensitivity of 76.9% (ME 89.1%) and specificity of 98.3% (ME 94.1%). Discussion: Our data show that ML substrate is well suitable for DH diagnostics.

RESUMO

Chronic pain remains a significant burden worldwide, and treatments are often limited by safety or efficacy. The decarboxylated form of L-arginine, agmatine, antagonizes N-methyl-d-aspartate receptors, inhibits nitric oxide synthase, and reverses behavioral neuroplasticity. We hypothesized that expressing the proposed synthetic enzyme for agmatine in the sensory pathway could reduce chronic pain without motor deficits. Intrathecal delivery of an adeno-associated viral (AAV) vector carrying the gene for arginine decarboxylase (ADC) prevented the development of chronic neuropathic pain as induced by spared nerve injury in mice and rats and persistently reversed established hypersensitivity 266 days post-injury. Spinal long-term potentiation was inhibited by both exogenous agmatine and AAV-human ADC (hADC) vector pre-treatment but was enhanced in rats treated with anti-agmatine immunoneutralizing antibodies. These data suggest that endogenous agmatine modulates the neuroplasticity associated with chronic pain. Development of approaches to access this inhibitory control of neuroplasticity associated with chronic pain may yield important non-opioid pain-relieving options.

RESUMO

For psoriasis, which affects up to 2% of the population and adalimumab is approved from the age of 4 years. Here, we present a middle-aged Italian man with long-term history of plaque psoriasis and psoriasis arthropathica and adalimumab therapy. He developed ulcers or nodules within the psoriatic plaques, resembling cutaneous infection with Leishmania infantum. TNF and other cytokines such as IL-12 and IFN-γ are central in the early control of the infection. Discontinuation of the anti-TNF-treatment resolved the infection without specific therapy.

RESUMO

People living with HIV-1 (PLWH) exhibit more rapid antibody decline following routine immunization and elevated baseline chronic inflammation than people without HIV-1 (PWOH), indicating potential for diminished humoral immunity during SARS-CoV-2 infection. Conflicting reports have emerged on the ability of PLWH to maintain humoral protection against SARS-CoV-2 coinfection during convalescence. It is unknown whether peak COVID-19 severity, along with HIV-1 infection status, associates with the quality and quantity of humoral immunity following recovery. Using a cross-sectional observational cohort from the United States and Peru, adults were enrolled 1-10 weeks after SARS-CoV-2 infection diagnosis or symptom resolution. Serum antibodies were analyzed for SARS-CoV-2-specific response rates, binding magnitudes, ACE2 receptor blocking, and antibody-dependent cellular phagocytosis. Overall, (a) PLWH exhibited a trend toward decreased magnitude of SARS-CoV-2-specific antibodies, despite modestly increased overall response rates when compared with PWOH; (b) PLWH recovered from symptomatic outpatient COVID-19 had comparatively diminished immune responses; and (c) PLWH lacked a corresponding increase in SARS-CoV-2 antibodies with increased COVID-19 severity when asymptomatic versus symptomatic outpatient disease was compared.

RESUMO

Background: Proportions of patients dying from the coronavirus disease-19 (COVID-19) vary between different countries. We report the characteristics; clinical course and outcome of patients requiring intensive care due to COVID-19 induced acute respiratory distress syndrome (ARDS). Methods: This is a retrospective, observational multicentre study in five German secondary or tertiary care hospitals. All patients consecutively admitted to the intensive care unit (ICU) in any of the participating hospitals between March 12 and May 4, 2020 with a COVID-19 induced ARDS were included. Results: A total of 106 ICU patients were treated for COVID-19 induced ARDS, whereas severe ARDS was present in the majority of cases. Survival of ICU treatment was 65.0%. Median duration of ICU treatment was 11 days; median duration of mechanical ventilation was 9 days. The majority of ICU treated patients (75.5%) did not receive any antiviral or anti-inflammatory therapies. Venovenous (vv) ECMO was utilized in 16.3%. ICU triage with population-level decision making was not necessary at any time. Univariate analysis associated older age, diabetes mellitus or a higher SOFA score on admission with non-survival during ICU stay. Conclusions: A high level of care adhering to standard ARDS treatments lead to a good outcome in critically ill COVID-19 patients.

RESUMO

Pericardial effusion and cardiac tamponade following renal transplantation have been recognized as a potentially serious complications associated with the use of sirolimus for immunosuppression. Our study aims to analyze the development of sirolimus-associated pericardial effusion. Patients who underwent renal transplantation at our institution between 2001 and 2014 were reviewed and the correlation between sirolimus exposure and pericardial effusion was determined. Nineteen out of 792 patients who received a renal transplant over this 14-year period (incidence 2.4%) developed symptomatic pericardial effusion (determined by the need for pericardiocentesis or a pericardial window). All patients had a pre-transplantation cardiac workup, including echocardiogram, which did not reveal the presence of pericardial effusion. Our cohort of patients is mostly male (57.9%) and Caucasian (73.7%), which is consistent with the makeup of transplant recipients at our center. The mean age was 52.42 years at the time of transplantation. The development of symptomatic pericardial effusions occurred at a mean of 5.06 (.5-9.8) years after renal transplant while on sirolimus therapy. Sirolimus levels at diagnosis were 5.19-7.47 ng/mL. No significant pericardial effusion (resulting in tamponade physiology) recurred after therapeutic intervention, including cessation of sirolimus with or without pericardial drainage. This study is the largest single-center report of the possible association between pericardial effusion in renal transplant recipients who received sirolimus. Due to the widespread use of sirolimus in organ transplantation, clinicians must remain vigilant for this potential cardiac complication.

RESUMO

Objective. Evaluation of C-MAC PM® in combination with a standard Macintosh blade size 3 in direct and indirect laryngoscopy and D-Blade® in indirect laryngoscopy in a simulated difficult airway. Primary outcome was defined as the best view of the glottic structures. Secondary endpoints were subjective evaluation and assessment of the intubation process. Methods. Prospective monocentric, observational study on 48 adult patients without predictors for difficult laryngoscopy/tracheal intubation undergoing orthopedic surgery. Every participant preoperatively received a cervical collar to simulate a difficult airway. Direct and indirect laryngoscopy w/o the BURP maneuver with a standard Macintosh blade and indirect laryngoscopy w/o the BURP maneuver using D-Blade® were performed to evaluate if blade geometry and the BURP maneuver improve the glottic view as measured by the Cormack-Lehane score. Results. Using a C-MAC PM® laryngoscope, D-Blade® yielded improved glottic views compared with the Macintosh blade used with either the direct or indirect technique. Changing from direct laryngoscopy using a Macintosh blade to indirect videolaryngoscopy using C-MAC PM® with D-Blade® improved the Cormack-Lehane score from IIb, III, or IV to I or II in 31 cases. Conclusion. The combination of C-MAC PM® and D-Blade® significantly enhances the view of the glottis compared to direct laryngoscopy with a Macintosh blade in patients with a simulated difficult airway. Trial Registration Number. This trial is registered under number NCT03403946.

RESUMO

A 75-year-old woman presented with minor hemoptysis. Past history included atrial fibrillation and rheumatic mitral stenosis. Bronchoscopy revealed a striking abnormality of widespread dilated mucosal and submucosal vessels. Initially the concern was whether there was widespread endobronchial malignancy; however, narrow band imaging (NBI) demonstrated the symmetrical uniform nature of the vessels. In addition, there was a focal area of in situ carcinoma with classic NBI features of malignancy. Following external-beam radiation therapy, NBI features had dramatically changed in the treated area which was now biopsy negative. The case highlights the utility of NBI in identifying endobronchial microvessel appearance even where there are widespread nonmalignant vessel changes in the bronchial mucosa.

RESUMO

BACKGROUND: A paucity of data exists on the impact of transfer status on outcomes for patients undergoing non-emergency (urgent) colorectal surgery. This study characterized transferred patients undergoing urgent colorectal surgery and determined which patient comorbidities significantly contributed to poor outcomes. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2013 was used. Urgent direct admissions undergoing colon, rectum, or small bowel operations were compared to urgent transfers using bivariate and multivariable analysis models. Primary outcomes were overall complications, hospital length of stay, and mortality. RESULTS: A total of 82,151 admissions were analyzed. After multivariable analysis, direct admission patients had nearly similar risk of complications (RR = 0.95; 95% CI 0.91-0.99) and length of hospital stay (7% shorter; 95% CI 4-9%), as well as no difference in mortality (RR = 0.94; 95% CI 0.80-1.11). CONCLUSIONS: Transfer status alone confers minimal risk toward higher complication rates and longer hospital length of stay in patients undergoing urgent colorectal surgery, and the poor outcomes observed in this cohort are largely due to patient comorbidities and disease severity. Our results suggest that outcomes in transferred colorectal surgery patients undergoing urgent operations depend mainly on operative acuity and clinical factors, and to a lesser degree transfer status.
