RESUMO

The aim of this study was to apply a state-of-the-art quantitative lipidomic profiling platform to uncover lipid alterations predictive of melanoma progression. Our study included 151 melanoma patients; of these, 83 were without metastasis and 68 with metastases. Plasma samples were analyzed using a targeted Lipidyzer™ platform, covering 13 lipid classes and over 1100 lipid species. Following quality control filters, 802 lipid species were included in the subsequent analyses. Total plasma lipid contents were significantly reduced in patients with metastasis. Specifically, levels of two out of the thirteen lipid classes (free fatty acids (FFAs) and lactosylceramides (LCERs)) were significantly decreased in patients with metastasis. Three lipids (CE(12:0), FFA(24:1), and TAG47:2-FA16:1) were identified as more effective predictors of melanoma metastasis than the well-known markers LDH and S100B. Furthermore, the predictive value substantially improved upon combining the lipid markers. We observed an increase in the cumulative levels of five lysophosphatidylcholines (LPC(16:0); LPC(18:0); LPC(18:1); LPC(18:2); LPC(20:4)), each individually associated with an elevated risk of lymph node metastasis but not cutaneous or distant metastasis. Additionally, seventeen lipid molecules were linked to patient survival, four of which (CE(12:0), CE(14:0), CE(15:0), SM(14:0)) overlapped with the lipid panel predicting metastasis. This study represents the first comprehensive investigation of the plasma lipidome of melanoma patients to date. Our findings suggest that plasma lipid profiles may serve as important biomarkers for predicting clinical outcomes of melanoma patients, including the presence of metastasis, and may also serve as indicators of patient survival.

RESUMO

Recent data indicate that distinct skin areas show different microbial/chemical milieu. Keratinocytes (KC) respond to these stimuli by producing cytokine mediators. Therefore, we aimed to determine KC-derived cytokine expression in distinct healthy skin regions (gland-poor [GP], sebaceous gland-rich [SGR] and apocrine gland-rich [AGR]), and their changes in skin diseases of the given regions (atopic dermatitis [AD], papulopustular rosacea [PPR] and psoriasis). Cytokines were analysed at the mRNA and protein levels, and literature analysis was performed for functional categorization. The three regions showed characteristically different cytokine patterns. GP was featured by an IL-25/IL-33/IL-36RA/IL-38/IL-18 cytokine milieu, SGR was characterized by IL-23/IL-17C/IL-18, and AGR skin exhibited a mixed IL-25/IL-33/IL-23/IL-18 profile. Literature analyses revealed different homeostatic and proinflammatory roles of these cytokine patterns (Th2 related in GP, Th17 related in SGR and mixed Th2/Th17 in AGR). In skin diseases which are primarily epidermal cytokine-driven (AD, PPR), the level of the regionally characteristic cytokines were further elevated, in contrast to the autoantigen-driven psoriasis, where the cytokine pattern was independent from the localization. Healthy skin regions are equipped with different KC-derived cytokine profiles, which may influence each region's capability of mediator production in certain types of dermatoses.

RESUMO

BACKGROUND: Intestinal symptoms are common in patients with hidradenitis suppurativa (HS). HS patients may experience a broad spectrum of chronic inflammatory intestinal disorders (CIID), not exclusive to inflammatory bowel diseases, which are diagnosed by colonoscopy and intestinal biopsies. The frequency of CIID in patients with HS has not been investigated. OBJECTIVE: The objectives of this study were to determine the occurrence of CIID in HS and characterize this clinical population. Furthermore, the feasibility of using faecal calprotectin (FC) test or anti-Saccharomyces cerevisiae antibody (ASCA) levels to assess the colonic inflammation of CIID in HS patients was investigated. METHODS: All newly diagnosed and untreated HS patients (n = 74) were referred to a gastroenterologist for FC followed by colonoscopy after informed consent. C-reactive protein (CRP), white blood cell count, nucleotide-binding oligomerization-domain-containing protein 2 (NOD2) polymorphism, and ASCA levels were measured. Patients were divided into HS-only and HS with CIID (HS + CIID) groups, based on the absence or presence of CIID. Laboratory and clinical parameters (age, gender, HS onset, clinical stage, family history, body mass index (BMI), smoking) were compared between the groups. RESULTS: Thirteen patients complained gastrointestinal symptoms prior to any examination, including 11 in the HS + CIID group. The CIID frequency in HS was 28.4% (n = 21/74), based on colonoscopy and histology. Significantly more patients had severe disease state in the HS + CIID group compared with the HS-only group, and BMI was significantly lower in the HS + CIID group (28.20 ± 5.58 vs. 32.74 ± 6.45, p = 0.006). FC positivity occurred significantly more in HS + CIID patients compared with HS-only patients (90.48% vs. 3.77%, p < 0.001), and ASCA IgG levels were significantly elevated in HS + CIID patients (22.08 ± 23.07 vs. 8.41 ± 10.94 U/mL, p = 0.001). The FC test identified HS + CIID patients with 96.23% specificity and 91.3% sensitivity, while ASCA displayed 77.8% sensitivity and 76.3% specificity. Blood count, CRP, and the presence of NOD2 polymorphisms were indifferent between the two groups. CONCLUSION: A high frequency of CIID was detected in the examined HS population. The noninvasive FC test has high sensitivity and specificity for diagnosing CIID in HS patients. Concomitant CIID and HS may indicate the need for an early-start for biological treatment.

RESUMO

Acute gastritis is often untreatable by acid secretion-inhibiting drugs. Understanding the protective mechanisms including the role of Transient Receptor Potential Ankyrin1 (TRPA1) and Vanilloid1 (TRPV1) channels localized on capsaicin-sensitive afferents and non-neuronal structures might identify novel therapeutic approaches. Therefore, we characterized a translational gastritis model using iodoacetamide (IAA) and investigated TRPA1/V1 expressions. Wistar rats and CD1, C57Bl/6J mice were exposed to IAA-containing (0.05, 0.1, 0.2, 0.3, 0.5%) drinking water for 7 or 14 days. Body weight and water consumption were recorded daily. Macroscopic lesions were scored, qualitative histopathologic investigation was performed, TRPA1/V1 immunopositivity and mRNA expressions were measured. IAA induced a concentration-dependent weight loss and reduced water intake in both species. Hyperemia, submucosal edema, inflammatory infiltration and hemorrhagic erosions developed after 7 days, while ulcers after 14 days in rats. Trpa1 mRNA/protein expressions were upregulated at both timepoints. Meanwhile, TRPV1 immunopositivity was upregulated in the gastric corpus after 0.05% IAA ingestion, but downregulated after 0.2%, whereas Trpv1 mRNA did not change. Interestingly, no macroscopic/microscopic changes were observed in mice. These are the first data for the concentration- and duration-dependent changes in the IAA-induced gastritis in rats accompanied by TRPA1 upregulation, therefore, its therapeutic potential in gastritis should further be investigated.

RESUMO

BACKGROUND: Unwarranted administration of antibiotics in acute pancreatitis presents a global challenge. The clinical reasoning behind the misuse is poorly understood. Our aim was to investigate current clinical practices and develop recommendations that guide clinicians in prescribing antibiotic treatment in acute pancreatitis. METHODS: Four methods were used. 1) Systematic data collection was performed to summarize current evidence; 2) a retrospective questionnaire was developed to understand the current global clinical practice; 3) five years of prospectively collected data were analysed to identify the clinical parameters used by medical teams in the decision making process, and finally; 4) the UpToDate Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was applied to provide evidence based recommendations for healthcare professionals. RESULTS: The systematic literature search revealed no consensus on the start of AB therapy in patients with no bacterial culture test. Retrospective data collection on 9728 patients from 22 countries indicated a wide range (31-82%) of antibiotic use frequency in AP. Analysis of 56 variables from 962 patients showed that clinicians initiate antibiotic therapy based on increased WBC and/or elevated CRP, lipase and amylase levels. The above mentioned four laboratory parameters showed no association with infection in the early phase of acute pancreatitis. Instead, procalcitonin levels proved to be a better biomarker of early infection. Patients with suspected infection because of fever had no benefit from antibiotic therapy. CONCLUSIONS: The authors formulated four consensus statements to urge reduction of unjustified antibiotic treatment in acute pancreatitis and to use procalcitonin rather than WBC or CRP as biomarkers to guide decision-making.

RESUMO

Consumption of capsaicin or its nonpungent analogues, capsinoids has been reported to affect energy expenditure and fat oxidation, although available data are still controversial. The aim of the present study was to conduct a meta-analysis regarding the effects of these substances on energy expenditure and respiratory quotient, with special emphasis on the role of body mass index (BMI) of the participants. Medical databases were systematically searched for papers. Of the 627 trials identified, 9 provided results suitable to be included in analysis. Data analysis showed that after ingestion of capsaicin or capsinoids the energy expenditure increased (245 kJ/day, 58.56 kcal/day, p = 0.030) and the respiratory quotient decreased (by 0.216; p = 0.031) indicating a rise in fat oxidation. Studies with mean BMI of the participants below 25 kg/m2 failed to report any effect of capsaicin or capsinoids on the energy expenditure (p = 0.718) or on the respiratory quotient (p = 0.444), but studies with mean BMI exceeding 25 kg/m2 demonstrated an increase in energy expenditure (292 kJ/day, 69.79 kcal/day, p = 0.023) and a marked decrease in respiratory quotient (-0.257, p = 0.036). Our data clearly suggest that capsaicin or capsiate could be a new therapeutic approach in obesity promoting a negative energy balance and increased fat oxidation.

RESUMO

Background and aim While many studies have discussed the different cannulation techniques used in patients with difficult biliary access, no previous meta-analyses have compared transpancreatic sphincterotomy (TPS) to other advanced techniques. Therefore, we aimed to identify all studies comparing the efficacy and adverse event rates of TPS with needle-knife precut papillotomy (NKPP), the most commonly used technique, and to perform a meta-analysis. Methods The Embase, PubMed, and Cochrane databases were searched for trials comparing the outcomes of TPS with NKPP up till December 2016. A meta-analysis focusing on outcome (cannulation success, post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP), post-procedural bleeding, and total adverse events) was performed. The population, intervention, comparison, outcome (PICO) format was used to compare these cannulation approaches. Five prospective and eight retrospective studies were included in our meta-analysis. Results NKPP has a significantly lower success rate (odds ratio [OR] 0.50, P = 0.046; relative risk [RR] 0.92, P = 0.03) and a higher rate of bleeding complications (OR 2.24, P = 0.02; RR 2.18, P = 0.02) than TPS. However, no significant differences were found in PEP (OR 0.79, P = 0.24; RR 0.80, P = 0.19), perforation (risk difference [RD] 0.01, P = 0.23), or total complication rates (OR 1.22, P = 0.44; RR 1.17, P = 0.47). Conclusion While TPS has a higher success rate in difficult biliary access and causes less bleeding than NKPP, there are no differences in PEP, perforation, or total complication rates between the two approaches. We conclude that TPS, in the hands of expert endoscopists, is a safe procedure, which should be used more widely in patients with difficult biliary access.

RESUMO

The recently published guidelines for acute pancreatitis (AP) suggest that enteral nutrition (EN) should be the primary therapy in patients suffering from severe acute pancreatitis (SAP); however, none of the guidelines have recommendations on mild and moderate AP (MAP). A meta-analysis was performed using the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). The following PICO (problem, intervention, comparison, outcome) was applied: P: nutrition in AP; I: enteral nutrition (EN); C: nil per os diet (NPO); and O: outcome. There were 717 articles found in Embase, 831 in PubMed, and 10 in the Cochrane database. Altogether, seven SAP and six MAP articles were suitable for analyses. In SAP, forest plots were used to illustrate three primary endpoints (mortality, multiorgan failure, and intervention). In MAP, 14 additional secondary endpoints were analyzed (such as CRP (C-reactive protein), WCC (white cell count), complications, etc.). After pooling the data, the Mann-Whitney U test was used to detect significant differences. Funnel plots were created for testing heterogeneity. All of the primary endpoints investigated showed that EN is beneficial vs. NPO in SAP. In MAP, all of the six articles found merit in EN. Analyses of the primary endpoints did not show significant differences between the groups; however, analyzing the 17 endpoints together showed a significant difference in favor of EN vs. NPO. EN is beneficial compared to a nil per os diet not only in severe, but also in mild and moderate AP.

RESUMO

Surgery has been considered the first choice of treatment in planocellular skin cancers. However, adjuvant radiotherapy is often required in R1 resection or in lymph node positivity. Inoperable cases are also treated with ionizing radiation with palliative purpose. The authors present a case report of a successful treatment of an 87-year-old diabetic patient with a T4N1M0 stage periauricular destructive tumour treated with 3D conformal adaptive radiotherapy. Complete remission occurred although the initial treatment aim was only palliation.

RESUMO

Schizophrenia is a serious neuropsychiatric disorder. Several brain structures, neurotransmitter systems, genetic and environmental risk factors are suspected in the background. Because of its complexity the mechanism of the disorder is not known exactly, so the treatment of patients is unsolved. In the research of schizophrenia application of the rodent models is widespread. In this study one of these models based on the effect of methylazoxymethanol- acetate (MAM) is described, which is a neurodevelopmental, validated rat model. This antimitotic agent is able to evoke a number of schizophrenic symptomes temporarily disrupting the prenatal neurogenesis. The model reproduces numerous histological and neurophysiological changes of the human disorder, moreover it also represents several behavioral and cognitive phenomena resembling those in schizophrenia. A salient advantage of the model is the demonstration of the diachronic feature of the disorder, that is, postpubertal appearance of the positive symptoms. This model provides widespread opportunities for manipulations of the symptoms, so that using it in the future investigations can lead to a better understanding of this disorder.

RESUMO

INTRODUCTION: One of the most serious complications of liver cirrhosis is variceal bleeding. Early recognition of the oesophageal varices is of primary importance in the prevention of variceal bleeding. Endoscopy is the only means to directly visualize varices and measure their size, as one of the most important predictor of the risk of bleeding. During the course of cirrhosis repeated oesophago-gastro-bulboscopic examinations are recommended. As these interventions are expensive and often poorly accepted by patients who may refuse further follow-up, there is a need for non-invasive methods to predict the progression of portal hypertension as well as the presence and the size of oesophageal varices. After several combinations of biological and ultrasonographical parameters proposed for the detection of advanced fibrosis, it was suggested that liver stiffness measured by transient elastography, a novel non-invasive technology may reflect not only fibrosis and portal pressure but it may even predict the presence or absence of large oesophageal varices in patients with cirrhosis. AIM: The aim of the authors was to study the diagnostic accuracy of transient elastography using FibroScan for selecting patients who are at risk of bearing large (Paquet-grade ≥ II) oesophageal varices and high risk of bleeding. METHOD: The authors performed upper tract endoscopy and transient elastography in 74 patients with chronic liver disease (27 patients with chronic hepatitis and 47 patients with liver cirrhosis). The relationships between the presence of oesophageal varices (Paquet-grade 0-IV) and liver stiffness (kPa), as well as the hematological and biochemical laboratory parameters (prothrombine international normalized ratio, platelet count, aspartate aminotransferase, alanine aminotransferase, albumin, and aspartate aminotransferase/platelet ratio index) were investigated. The predictive role of liver stiffness for screening patients with varices and those who are at high risk of variceal bleeding was also analysed. RESULTS: Liver stiffness values significantly correlated with the grade of oesophageal varices (Paquet-grade) (r = 0.67, p<0.0001). The liver stiffness value of 19.2 kPa was highly predictive for the presence of oesophageal varices (AUROC: 0.885, 95% CI: 0.81-0.96) and for the presence of high grade varices (P≥II) (AUROC: 0.850, 95% CI: 0.754-0.94). Using the cut-off value of 19.2 kPa, the sensitivity of transient elastography was 85%, specificity was 87%, positive predictive value was 85%, negative predictive value was 87% and validity was 86% for the detection of varices. Liver stiffness values less than 19.2 kPa were highly predicitive for the absence of large (P≥II) varices (sensitivity, 95%; specificity, 70%; positive predictive value, 54%; negative predictive value, 97%). CONCLUSIONS: Transient elastography may help to screen patients who are at high risk of bearing large (P≥II) oesophageal varices which predict variceal bleeding and, therefore, need endoscopic screening. Lives stiffness values higher than 19.2 kPa indicate the need for oesophageal-gastro-bulboscopy, while liver stiffness values lower than 19.2 kPa make the presence of large oesophageal varices unlikely.

RESUMO

Introduction: Erdheim-Chester disease (ECD) is a rare disease that belongs to the group of Dendritic and histiocytic neoplasms. Only 2000 cases have been reported worldwide. It can present with a wide range of symptoms, making a differential diagnosis especially difficult. The primary and most important diagnostic tool is a biopsy of the affected organ/tissue. Nowadays the analysis of different mutations affecting the BRAF and MAPK pathways makes it possible to use targeted treatments, such as vemurafenib, dabrafenib, or cobimetinib. Objective: Our aim is to present the results of three male patients treated in our hematology department. Results: Our BRAF mutation-positive patient presented with retroperitoneal tissue proliferation and diabetes insipidus. The initial therapy of choice was dabrafenib. After 3 months of treatment, 18F-fluoro-deoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT) scans showed regression, and after 2 years of treatment, no disease activity was detected. In our second patient, a recurrent febrile state (not explained by other reasons) and diabetes insipidus suggested the diagnosis. A femoral bone biopsy confirmed BRAF-negative ECD. The first-line therapy was interferon-alpha. After 3 months of treatment, no response was observed on 18FDG-PET/CT, and treatment with cobimetinib was started. The control 18FDG-PET/CT imaging was negative. Our third patient was evaluated for dyspnea, and a CT scan showed fibrosis with hilar lymphadenomegaly. A lung biopsy confirmed BRAF-negative ECD. We started treatment with interferon-alpha, but unfortunately, no improvement was observed. Second-line treatment with cobimetinib resulted in a partial metabolic response (PMR) according to control 18FDG-PET/CT. Conclusions: Our results demonstrate that an appropriately chosen treatment can lead to a good therapeutic response, but dose reduction may be necessary due to side effects. With advanced targeted therapeutic treatment options, survival and quality of life are significantly improved.

RESUMO

INTRODUCTION: Acute gastrointestinal bleeding (GIB) is a life-threatening emergency with a critical economic burden. As a result of bleeding, anaemia often requires intravenous or oral iron supplementation. Elderly patients are even more prone to untoward outcomes after hospital discharge if iron supplementation is inefficient. There is a gap in current guidelines on which supplementation route clinicians should choose. We aim to investigate the effect of one dose of intravenous iron therapy versus 3-month oral iron administration on anaemia in an elderly population. METHODS AND ANALYSIS: The FIERCE study is an open-label, randomised controlled, two-armed trial. At least 48 hours after the acute non-variceal GIB treatment, patients will be recruited in participating centres. A random sequence generator will allocate the participants to group A (intravenous ferric carboxymaltose, 1000 mg) or group B (oral ferrous sulfate (FS), ca. 200 mg every day) with an allocation ratio of 1:1 on the day of the planned discharge from the hospital. Randomisation will be stratified for participating centres and the need for transfusion within the same hospitalisation before recruitment to the trial. Quality of life assessment, functional measurement and laboratory tests will be performed at baseline, 1 and 3 months±7 days after enrolment to the trial. The primary endpoint is a composite endpoint, including all-cause mortality, anaemia-associated unplanned emergency visit and anaemia-associated unplanned hospital admission within 3 months of enrolment in the trial. ETHICS AND DISSEMINATION: The study has been approved by the relevant organisation, the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (46395-5/2021/EÜIG). We will disseminate our results to the medical community and will publish our results in peer-reviewed journals. TRIAL REGISTRATION: The trial has been registered at ClinicalTrials.gov (NCT05060731).

RESUMO

Background: Prognostic classification of metastatic melanoma patients treated with anti-PD-1 is of great interest to clinicians. Objective: We aimed to determine the anti-PD-1 treatment related prognostic performance of demographics, clinical and histological prognostic markers and baseline serum S100B and LDH levels in advanced melanoma. Methods: A total of 200 patients with unresectable metastatic melanoma were included in this retrospective study. 34.5% had stage M1c disease and 11.5% had stage M1d disease at the start of therapy. 30% had pT4b primary melanoma. 55.5% had elevated baseline serum S100B levels and 62.5% had elevated baseline serum LDH levels. We analysed the risk of death using univariate and multivariate Cox proportional-hazards models and the median overall (OS) and progression-free (PFS) survival using the Kaplan-Meier estimator. Results: The median follow-up time from the start of anti-PD-1 treatment in patients who were alive at the end of the study (N=81) was 37 months (range: 6.1-95.9). The multivariate Cox regression analysis showed that M1c stage (vs. M1a, p=0.005) or M1d stage at the start of therapy (vs. M1a, p=0.001), pT4b category (vs. pT1a, p=0.036), elevated baseline serum S100B levels (vs. normal S100B, p=0.008) and elevated LDH levels (vs. normal LDH, p=0.049) were independently associated with poor survival. The combination of M1d stage, elevated baseline serum S100B and LDH levels and pT4b category was associated with a very high risk of death (HR 4.72 [1.81; 12.33]). In the subgroup of patients with pT4b primary melanoma, the median OS of patients with normal serum S100B levels was 37.25 months [95% CI 11.04; 63.46]), while the median OS of patients with elevated serum S100B levels was 8.00 months [95% CI 3.49; 12.51]) (p<0.001); the median OS of patients with normal serum LDH levels was 41.82 months [95% CI 11.33; 72.32]), while the median OS of patients with elevated serum LDH levels was 12.29 months [95% CI 4.35; 20.23]) (p=0.002). Conclusion: Our real-world study indicates that the prognostic role of primary melanoma parameters is preserved in anti-PD-1 treated stage IV patients. Furthermore, there seems to be perspective in combining clinical, histological and serum prognostic markers in a prognostic model.

RESUMO

The early detection of melanoma relapse can improve patient survival; thus, there is a great need for easily accessible biomarkers that facilitate the diagnosis of metastatic disease. We investigated the diagnostic effect of blood biomarkers such as lactate dehydrogenase (LDH), S100B, and osteopontin in the detection of metastases. Clinical data and peripheral blood samples of 206 melanoma patients were collected (no metastasis, N = 120; metastasis, N = 86). The discriminative power of blood biomarkers, patient demographics, and clinicopathological parameters of primary melanomas were evaluated using univariate and multivariate logistic regression models and receiver operating characteristic (ROC) analysis to determine the area under the curve (AUC). Plasma osteopontin levels showed a significant and independent effect on the probability of metastasis, similar to serum S100B levels. In addition, the location of the primary tumor on the lower extremities and the American Joint Committee on Cancer (AJCC) categories pT2b-3a, pT3b-4a, and pT4b were associated with the diagnosis of metastasis. Importantly, the combination of the three blood biomarkers and primary tumor localization and AJCC pT category yielded excellent discrimination (AUC: training set: 0.803; validation set: 0.822). In conclusion, plasma osteopontin can be classified as a melanoma biomarker; moreover, by combining clinicopathological prognostic variables, the diagnostic effect of blood biomarkers in the detection of metastatic melanoma can be improved.

RESUMO

The aim of our analysis was to evaluate the efficacy of cabozantinib in patients with metastatic renal cell carcinoma. Cabozantinib therapy initiated between 01/01/2019 and 31/12/2022 was evaluated based on a retrospective review of data from 14 renal centers in Hungary. The starting dose was 60 or 40 mg. Physical examinations and laboratory tests were performed every 4 weeks and imaging studies 3-monthly. Tumor response was assessed according to RECIST 1.1, and toxicity according to NCI CTCAE 4.0. A total of 230 patient records were evaluated, 201 (87.4%) of them had clear cell RCC. Cabozantinib was administered as third, second and first-line treatment in 48.7%, 38.3% and <5% of cases, respectively. Dose reductions occurred in 62.6% and treatment interruption in 6.5%. Duration of therapy was 10.03 months, which was independent of dose reduction. Overall tumor response rate was 39.2% and clinical benefit was 82.8%. The duration of first-, second-, third- and fourth-line treatment was 11.47, 8.03, 11.57 and 10.13 months, respectively. Overall survival from the start of therapy was 22.0 months. Cabozantinib therapy in daily practice was more beneficial than according to registry study results. Dose reduction did not affect efficacy.

RESUMO

Under what conditions can organized labour successfully politicize the European integration process across borders? To answer this question, we compare the European Citizens' Initiatives (ECIs) of two European trade union federations: EPSU's successful Right2Water ECI and ETF's unsuccessful Fair Transport ECI. Our comparison reveals that actor-centred factors matter - namely, unions' ability to create broad coalitions. Successful transnational labour campaigns, however, also depend on structural conditions, namely, the prevailing mode of EU integration pressures faced by unions at a given time. Whereas the Right2Water ECI pre-emptively countered commodification attempts by the European Commission in water services, the Fair Transport ECI attempted to ensure fair working conditions after most of the transport sector had been liberalized. Vertical EU integration attempts that commodify public services are thus more likely to generate successful transnational counter-movements than the horizontal integration pressures on wages and working conditions that followed earlier successful EU liberalization drives.
