Case report: Thoracoscopic repair of renal ectopia associated with congenital diaphragmatic hernia: Report of two cases
Renal ectopia is a rare anomaly which may occur due to an abnormal ascent of the kidney. It is usually asymptomatic and does not require treatment. Intrathoracic renal ectopia with concomitant congenital diaphragmatic hernia (CDH) is extremely rare. All symptomatic CDH cases must be treated with open or thoracoscopic repair. During plication of the diaphragm, care must be taken to avoid renal injury. Following, we present two rare variants of CDH with concomitant renal ectopia managed thoracoscopically. Postoperative recovery was uneventful. Doppler ultrasound study performed one month after surgery confirmed normal vascularity of the kidneys and the absence of urinary outflow obstruction.KEYWORDS: Congenital diaphragmatic hernia; Renal ectopia; Thoracoscopic repai
Thick Line Segment Detection with Fast Directional Tracking
International audienceThis paper introduces a fully discrete framework for a new straight line detector in gray-level images, where line segments are enriched with a thickness parameter intended to provide a quality criterion on the extracted feature. This study is based on a previous work on interactive line detection in gray-level images. At first, a better estimation of the segment thickness and orientation is achieved through two main improvements: adaptive directional scans and control of assigned thickness. Then, these advances are exploited for a complete unsupervised detection of all the line segments in an image. The new thick line detector is left available in an online demonstration

Ruxolitinib for Glucocorticoid-Refractory Acute Graft-versus-Host Disease
BACKGROUND: Acute graft-versus-host disease (GVHD) remains a major limitation of allogeneic stem-cell transplantation; not all patients have a response to standard glucocorticoid treatment. In a phase 2 trial, ruxolitinib, a selective Janus kinase (JAK1 and JAK2) inhibitor, showed potential efficacy in patients with glucocorticoid-refractory acute GVHD. METHODS: We conducted a multicenter, randomized, open-label, phase 3 trial comparing the efficacy and safety of oral ruxolitinib (10 mg twice daily) with the investigator's choice of therapy from a list of nine commonly used options (control) in patients 12 years of age or older who had glucocorticoid-refractory acute GVHD after allogeneic stem-cell transplantation. The primary end point was overall response (complete response or partial response) at day 28. The key secondary end point was durable overall response at day 56. RESULTS: A total of 309 patients underwent randomization; 154 patients were assigned to the ruxolitinib group and 155 to the control group. Overall response at day 28 was higher in the ruxolitinib group than in the control group (62% [96 patients] vs. 39% [61]; odds ratio, 2.64; 95% confidence interval [CI], 1.65 to 4.22; P<0.001). Durable overall response at day 56 was higher in the ruxolitinib group than in the control group (40% [61 patients] vs. 22% [34]; odds ratio, 2.38; 95% CI, 1.43 to 3.94; P<0.001). The estimated cumulative incidence of loss of response at 6 months was 10% in the ruxolitinib group and 39% in the control group. The median failure-free survival was considerably longer with ruxolitinib than with control (5.0 months vs. 1.0 month; hazard ratio for relapse or progression of hematologic disease, non-relapse-related death, or addition of new systemic therapy for acute GVHD, 0.46; 95% CI, 0.35 to 0.60). The median overall survival was 11.1 months in the ruxolitinib group and 6.5 months in the control group (hazard ratio for death, 0.83; 95% CI, 0.60 to 1.15). The most common adverse events up to day 28 were thrombocytopenia (in 50 of 152 patients [33%] in the ruxolitinib group and 27 of 150 [18%] in the control group), anemia (in 46 [30%] and 42 [28%], respectively), and cytomegalovirus infection (in 39 [26%] and 31 [21%]). CONCLUSIONS: Ruxolitinib therapy led to significant improvements in efficacy outcomes, with a higher incidence of thrombocytopenia, the most frequent toxic effect, than that observed with control therapy
Inventory Signals
How does operational competence translate into market value, when firms cannot credibly communicate their competence to the market? I consider the example of inventory and fill rates. When the market sees a high-inventory firm, it cannot tell whether the inventory is due to incompetence or a strategy to enhance fill rate. Firms might decide to signal their competence to the market by carrying less inventory. I show conditions for separating and pooling perfect Bayesian equilibria. I also provide empirical evidence for this theory that inventory has a signaling role. The theory could potentially provide a framework that describes one way in which a range of operational competences such as purchasing and outsourcing, translate to market value. Practically, it has implications for firms, such as how to strategically communicate to the market, reward managers, or even whether to go public and be subject to market pressures
Upstream Supply Chain Visibility and Complexity Effect on Focal Company’s Sustainable Performance: Indian Manufacturers’ Perspective
Understanding supply chain sustainability performance is increasingly important for supply chain researchers and managers. Literature has considered supply chain sustainability and the antecedents of performance from a triple bottom line (economic, social, and environmental) perspective. However, the role of supply chain visibility and product complexity contingency in achieving sustainable supply chain performance has not been explored in depth. To address this gap, this study utilizes a contingent resource-based view theory perspective to understand the role of product complexity in shaping the relationship between upstream supply chain visibility (resources and capabilities) and the social, environmental, and economic performance dimensions. We develop and test a theoretical model using survey data gathered from 312 Indian manufacturing organizations. Our findings indicate that supply chain visibility (SCV) has significant influence on social and environmental performance under the moderation effect of product complexity. Hence, the study makes significant contribution to the extant literature by examining the impact of SCV under moderating effect of product complexity on social performance and environmental performance
