98, and 2.43, respectively, P less then 0.021), as was BMI in the upper quartile (HR = 2.59, 2.91, and 2.29, respectively, P less then 0.013).Conclusion BMI in the lower and upper quartiles at diagnosis and during follow-up was associated with a more severe disease course in children with IBD.What is Known• Inflammatory bowel disease (IBD) has been associated with underweight and malnutrition.• The impacts of weight and body mass index (BMI) on the presentation and course of IBD have been mainly investigated in the adult population.What is New• In the era of the obesity epidemic, this study identifies both low and high BMIs at diagnosis and at follow-up as a marker for poor outcome in pediatric IBD.• The results support using BMI as a predictor of IBD course and prognosis.The Rescorla-Wagner (R-W) model describes human associative learning by proposing that an agent updates associations between stimuli, such as events in their environment or predictive cues, proportionally to a prediction error. While this model has proven informative in experiments, it has been posited that humans selectively attend to certain cues to overcome a problem with the R-W model scaling to large cue dimensions. We formally characterize this scaling problem and provide a solution that involves limiting attention in a R-W model to a sparse set of cues. Given the universal difficulty in selecting features for prediction, sparse attention faces challenges beyond those faced by the R-W model. We demonstrate several ways in which a naive attention model can fail explain those failures and leverage that understanding to produce a Sparse Attention R-W with Inference framework (SAR-WI). The SAR-WI framework not only satisfies a constraint on the number of attended cues, it also performs as well as the R-W model on a number of natural learning tasks, can correctly infer associative strengths, and focuses attention on predictive cues while ignoring uninformative cues. Given the simplicity of proposed alterations, we hope this work informs future development and empirical validation of associative learning models that seek to incorporate sparse attention.Background The thumb's radial collateral ligament (RCL) plays an important role in stabilizing the first metacarpophalangeal joint (MCP-1). RCL injuries are rare and treatment recommendations are inconsistent in the current literature. The aim of this study was to report on long-term outcomes following surgical repair of thumb RCL tear and to identify prognostic risk factors for treatment failure. Methods Patients with RCL tear from 10/1998 to 10/2019 were included in the present retrospective single center cohort study. In follow-up visits, participants were assessed regarding pain, range of motion and strength as well as with disability of shoulder, arm and hands (DASH), and the Short-Form 36 (SF36) questionnaires. Finally, predictive factors of postoperative deficits were identified. Results 43 patients fulfilled inclusion criteria. Median age was 43.5 years (range 18-80 years). The most frequent mechanism of injury was a fall or impact. Bony avulsions were identified in 46.5% (20/43). Time from injury to surgery was 12 days (0-276 days). One Stener-like lesion was observed intraoperatively among our patients. After surgical repair, the MCP-1 joint was stable in every patient. Mean time to follow-up was 5.3 years (1 month to 17 years). Persistency of pain in the MCP-1 joint was reported by 11 patients. Postoperative averaged score was 3.75 on DASH and 44.96 on SF36, respectively. The average grip and pinch strength was 32.7 kg and 8.37 kg, respectively. Predictive factors of postoperative deficits were delay of surgery of > 3 weeks (OR 10.72, p 0.017) and palmar subluxation prior to surgery (OR 8.86, p 0.019). Conclusion Long-term follow-up has proven that surgical repair of RCL enables the patient to regain adequate stability and strength of the MCP-1 joint and minimizes disability. Predictive risk factors of pain persistency after surgery are surgical delay and palmar subluxation of the MCP-1 joint.Unconventional oil and gas (UOG) drilling has expanded rapidly across the United States, including in the Fayetteville Shale formation in north-central Arkansas where drilling began in 2004. As one of the oldest regions of UOG activity in the United States, this area has experienced significant land-use changes, specifically development of natural habitat and agricultural land for gas infrastructure. In recent years, drilling of new wells has stopped and production has declined. By 2017, 1038 wells had ceased production and been abandoned, which makes them eligible for land reclamation. However, most of these sites (80%) have not been reclaimed and continue to cause losses in ecosystem services. If reclamation was performed on lands associated with abandoned infrastructure, we estimate more than $2 million USD annually in agricultural, timber, and carbon sequestration values would be gained. These benefits far outweigh the costs of reclamation, especially since the benefits accrue over time and reclamation is a short-term cost. Our estimates indicate a 2-4 year break-even time period when cumulative ecosystem services benefits will outweigh reclamation costs. We predicted a well-abandonment rate of 155 per year until 2050 when 98% of wells will be abandoned, which indicates great potential for future ecosystem services restoration. Thus, we recommend that Arkansans at the government and citizen level work to restore lands impacted by UOG development in the Fayetteville Shale region so that their value to landowners and society can be recovered, which will enhance long-term economic and environmental benefits.Purpose The NMOC-3WAY catheter® is a novel urinary catheter for men that can be used to inject a local anesthetic into the urethra. We sought to assess whether the injection of a local anesthetic into the urethra via the NMOC-3WAY catheter® would reduce catheter-related bladder discomfort (CRBD) after endovascular aneurysm repair (EVAR). learn more Methods Adult male patients who underwent elective EVAR for abdominal aortic aneurysms were randomly assigned to the 2% lidocaine group and the normal saline group (control group). CRBD was evaluated at 0, 1, 2, 4, and 6 h after surgery. The primary outcome was the incidence of CRBD at 0 h after surgery. Results Data for 37 patients (19 in the lidocaine group and 18 in the control group) were analyzed. CRBD was observed at 0 h in six patients (31.6%; mild, n = 5; moderate, n = 1) in the lidocaine group and in five patients (27.8%; mild, n = 1; moderate, n = 3; severe, n = 1) in the control group. The control group showed a tendency to have severe CRBD at 0 h, although there was no significant difference in either the incidence (P = 0.
