External influences on local institutions: spatial dependence and openness

There are both empirical and theoretical arguments for the thesis that external factors have an impact on domestic institutional quality. Consequently, external factors may have large effects on domestic income via local institutions. This paper investigates the role of external factors by estimating the impact of openness and the institutional environment of proximate countries on local institutions and local income. In a 107-country cross-section, we find that both openness (in trade, and especially FDI) and the institutional indicators of nearby countries have an independent impact on local institutional indicators. The effects on income levels are not symmetric, however. We estimate that trade openness plays a major role as a direct determinant of the income level, and a smaller role in determining local institutions. By contrast, institutions of nearby countries are a prime determinant of local institutions, but carry no direct effects on local income levels.Economic institutions, Spatial spillovers, Economic openness, Income differences

Does Institutional Change Spread Across Countries? Explaining Spatial Patterns in Human Rights

If a country improves its human rights record, will neighbouring countries benefit? Beneficial spillovers could justify intervention by the UN or one of the many other organisations that internationally fight human rights violations. We document that countries' human rights performances often resemble the human rights situation of their neighbours. However, exploiting time variation in a spatial panel, we find that much of that resemblance is simply determined by the shared geographical location. Changes in neighbouring countries have little influence on local human rights, suggesting that contemporaneous spillovers and interactions are limited.</p

Epidemiology, treatment, costs, and longterm outcomes of patients with fireworksrelated injuries (ROCKET); A multicenter prospective observational case series

Objective People in the Netherlands are legally allowed to celebrate New Year's Eve with consumer fireworks. The aim of this study was to provide detailed information about the patient and injury characteristics, medical and societal costs, and clinical and functional outcome in patients with injuries resulting from this tradition. Methods A multicenter, prospective, observational case series performed in the Southwest Netherlands trauma region, which reflects 15% of the country and includes a level I trauma center, a specialized burn center, a specialized eye hospital, and 13 general hospitals. All patients with any injury caused by consumer fireworks, treated at a Dutch hospital between December 1, 2017 and January 31, 2018, were eligible for inclusion. Exclusion criteria were unknown contact information or insufficient understanding of Dutch or English language. The primary outcome measure was injury characteristics. Secondary outcome measures included treatment, direct medical and indirect societal costs, and clinical and functional outcome until one year after trauma. Results 54 out of 63 eligible patients agreed to participate in this study. The majority were males (N = 50; 93%), 50% were children below 16 years of age, and 46% were bystanders. Injuries were mainly located to the upper extremity or eyes, and were mostly burns (N = 38; 48%) of partial thickness (N = 32; 84%). Fifteen (28%) patients were admitted and 11 (20%) patients needed surgical treatment. The mean total costs per patient were 6,320 (95% CI 3,400 to 9,245). The most important cost category was hospital admission. Only few patients reported complaints in patient-reported quality of life and functional outcome after 12 months follow-up. Conclusion This study found that young males are most vulnerable for fireworks injuries and that most injuries consist of burns, located to the arm and hand, and eye injuries. On the long-term only few patients experienced

Performance of the 4-Level Pulmonary Embolism Clinical Probability Score (4PEPS) in the diagnostic management of pulmonary embolism:An external validation study

Background: The recently published 4-level Pulmonary Embolism Clinical Probability Score (4PEPS) integrates different aspects from currently available diagnostic strategies to further reduce imaging testing in patients with clinically suspected pulmonary embolism (PE). Aim: To externally validate the performance of 4PEPS in an independent cohort. Methods: In this post-hoc analysis of the prospective diagnostic management YEARS study, the primary outcome measures were discrimination, calibration, efficiency (proportion of imaging tests potentially avoided), and failure rate (venous thromboembolism (VTE) diagnosis at baseline or follow-up in patients with a negative 4PEPS algorithm). Multiple imputation was used for missing 4PEPS items. Based on 4PEPS, PE was considered ruled out in patients with a very low clinical pre-test probability (CPTP) without D-dimer testing, in patients with a low CPTP and D-dimer &lt;1000 μg/L, and in patients with a moderate CPP and D-dimer below the age-adjusted threshold. Results: Of the 3465 patients, 474 (14 %) were diagnosed with VTE at baseline or during 3-month follow-up. Discriminatory performance of the 4PEPS items was good (area under ROC-curve, 0.82; 95%CI, 0.80–0.84) as was calibration. Based on 4PEPS, PE could be considered ruled out without imaging in 58 % (95%CI 57–60) of patients (efficiency), for an overall failure rate of 1.3 % (95%CI 0.86–1.9). Conclusion: In this retrospective external validation, 4PEPS appeared to safely rule out PE with a high efficiency. Nevertheless, although not exceeding the failure rate margin by ISTH standards, the observed failure rate in our analysis appeared to be higher than in the original 4PEPS derivation and validation study. This highlights the importance of a prospective outcome study.</p

A randomized controlled trial of nonoperative treatment versus open reduction and internal fixation for stable, displaced, partial articular fractures of the radial head: The RAMBO trial

Background: The choice between operative or nonoperative treatment is questioned for partial articular fractures of the radial head that have at least 2 millimeters of articular step-off on at least one radiograph (defined as displaced), but less than 2 millimeter of gap between the fragments (defined as stable) and that are not associated with an elbow dislocation, interosseous ligament injury, or other fractures. These kinds of fractures are often classified as Mason type-2 fractures. Retrospective comparative studies suggest that operative treatment might be better than nonoperative treatment, but the long-term results of nonoperative treatment are very good. Most experts agree that problems like reduced range of motion, painful crepitation, nonunion or bony ankylosis are infrequent with both nonoperative and operative treatment of an isolated displaced partial articular fracture of the radial head, but determining which patients will have problems is difficult. A prospective, randomized comparison would help minimize bias and determine the balance between operative and nonoperative risks and benefits. Methods/Design. The RAMBO trial (Radial Head - Amsterdam - Amphia - Boston - Others) is an international prospective, randomized, multicenter trial. The primary objective of this study is to compare patient related outcome defined by the \u27Disabilities of Arm, Shoulder and Hand (DASH) score\u27 twelve months after injury between operative and nonoperative treated patients. Adult patients with partial articular fractures of the radial head that comprise at least 1/3rd of the articular surface, have ≥ 2 millimeters of articular step-off but less than 2 millimeter of gap between the fragments will be enrolled. Secondary outcome measures will be the Mayo Elbow Performance Index (MEPI), the Oxford Elbow Score (OES), pain intensity through the \u27Numeric Rating Scale\u27, range of motion (flexion arc and rotational arc), radiographic appearance of the fracture (heterotopic ossification, radiocapitellar and ulnohumeral arthrosis, fracture healing, and signs of implant loosening or breakage) and adverse events (infection, nerve injury, secondary interventions) after one year. Discussion. The successful completion of this trial will provide evidence on the best treatment for stable, displaced, partial articular fractures of the radial head. Trial registration. The trial is registered at the Dutch Trial Register: NTR3413. © 2014Bruinsma et al.; licensee BioMed Central Ltd

Vuurwerkletsel in Zuidwest-Nederland rond de jaarwisseling 2017-2018

OBJECTIVE: To report the number of patients with firework-related injuries treated in December 2017 and January 2018 in a hospital in the south-west Netherlands trauma region, and to provide details about the types of firework used and the specific injuries. DESIGN: A prospective multicentre cohort study (NTR6793). METHODS: Patients of all ages with firework-related injuries were eligible for inclusion. The injury had to have been sustained between 1 December 2017 and 31 January 2018, and treated at a hospital in the south-west Netherlands trauma region (approximately 2.5 million inhabitants). Data were extracted from patients' medical files and additional information was obtained from patient interviews. RESULTS: Fifty-four patients were included. The majority were male (93%) and the median age was 15 years. Twenty-five (46%) patients were bystanders and 12 (22%) were injured by illegal fireworks. Fifty patients were injured by bangers (n=22) or decorative fireworks (n=28). The patients had a total of 79 injuries, of which 29 (37%) were localised to the upper extremity and 19 (24%) to the eyes. Most upper extremity injuries were burns (69%), primarily partial thickness. Of the eye injuries, 14 were caused by blunt trauma, seven by chemical trauma, and one by penetrating trauma. Three patients sustained indirect firework-related injuries. CONCLUSION: Between 1 December 2017 and 31 January 2018 in the south-west Netherlands trauma region mainly teenage males and bystanders sustained firework-related injuries. Most injuries were upper extremity burns and eye injuries, mainly due to legal fireworks and bangers or decorative fireworks. The extent of the sample indicatDoel Een volledig overzicht geven van het aantal vuurwerkslachtoffers dat in december 2017 en januari 2018 behandeld werd in een ziekenhuis in de traumaregio Zuidwest-Nederland, het gebruikte soort vuurwerk en de specifieke letsels. Opzet Een prospectieve, multicentrische cohortstudie (NTR6793). Methode Patiënten van alle leeftijden met vuurwerkletsel kwamen in aanmerking voor inclusie. Het letsel moest zijn ontstaan in de periode 1 december 2017-31 januari 2018 en zijn behandeld in een ziekenhuis in de traumaregio Zuidwest-Nederland (circa 2,5 miljoen inwoners). Gegevens werden verzameld vanuit het patiëntendossier en aanvullende gegevens werden verkregen tijdens een interview. Resultaten Er werden 54 patiënten geïncludeerd. Het overgrote deel betrof mannen (93%) en de mediane leeftijd was 15 jaar. 25 gewonden (46%) waren omstander en 12 mensen (22%) raakten gewond door illegaal vuurwerk. Van de 54 patiënten raakten er 50 gewond door knalvuurwerk (n = 22) of siervuurwerk (n = 28). De 54 geïncludeerde patiënten hadden 79 letsels; het letsel was 29 keer (37%) gelokaliseerd aan armen of handen en 19 keer (24%) aan de ogen. Letsel aan de arm of hand bestond voornamelijk uit brandwonden (69%), met name tweedegraads. Oogletsel werd 14 keer door stomp inwerkend geweld veroorzaakt, 7 keer door chemisch letsel en 1 keer werd het oog gepenetreerd. Er raakten 3 patiënten indirect gewond door vuurwerk. Conclusie In de traumaregio Zuidwest-Nederland raakten in de 2 maanden rond de jaarwisseling 2017-2018 vooral minderjarige mannen en omstanders gewond. Slachtoffers liepen met name brandwonden aan armen of handen of oogletsel op. De verwondingen waren met name het gevolg van legaal knal- en siervuurwerk. Door de omvang van de steekproef lijken de studiebevindingen goed te extrapoleren naar het gehele land

Plasma lipid profiles discriminate bacterial from viral infection in febrile children

Fever is the most common reason that children present to Emergency Departments. Clinical signs and symptoms suggestive of bacterial infection are often non-specific, and there is no definitive test for the accurate diagnosis of infection. The 'omics' approaches to identifying biomarkers from the host-response to bacterial infection are promising. In this study, lipidomic analysis was carried out with plasma samples obtained from febrile children with confirmed bacterial infection (n = 20) and confirmed viral infection (n = 20). We show for the first time that bacterial and viral infection produces distinct profile in the host lipidome. Some species of glycerophosphoinositol, sphingomyelin, lysophosphatidylcholine and cholesterol sulfate were higher in the confirmed virus infected group, while some species of fatty acids, glycerophosphocholine, glycerophosphoserine, lactosylceramide and bilirubin were lower in the confirmed virus infected group when compared with confirmed bacterial infected group. A combination of three lipids achieved an area under the receiver operating characteristic (ROC) curve of 0.911 (95% CI 0.81 to 0.98). This pilot study demonstrates the potential of metabolic biomarkers to assist clinicians in distinguishing bacterial from viral infection in febrile children, to facilitate effective clinical management and to the limit inappropriate use of antibiotics

Identification of regulatory variants associated with genetic susceptibility to meningococcal disease.

Non-coding genetic variants play an important role in driving susceptibility to complex diseases but their characterization remains challenging. Here, we employed a novel approach to interrogate the genetic risk of such polymorphisms in a more systematic way by targeting specific regulatory regions relevant for the phenotype studied. We applied this method to meningococcal disease susceptibility, using the DNA binding pattern of RELA - a NF-kB subunit, master regulator of the response to infection - under bacterial stimuli in nasopharyngeal epithelial cells. We designed a custom panel to cover these RELA binding sites and used it for targeted sequencing in cases and controls. Variant calling and association analysis were performed followed by validation of candidate polymorphisms by genotyping in three independent cohorts. We identified two new polymorphisms, rs4823231 and rs11913168, showing signs of association with meningococcal disease susceptibility. In addition, using our genomic data as well as publicly available resources, we found evidences for these SNPs to have potential regulatory effects on ATXN10 and LIF genes respectively. The variants and related candidate genes are relevant for infectious diseases and may have important contribution for meningococcal disease pathology. Finally, we described a novel genetic association approach that could be applied to other phenotypes
