Effects of Late-Summer Prescribed Fire on Botanical Composition, Soil Cover, and Forage Production in Caucasian Bluestem-Infested Rangeland in the Kansas Smoky Hills: Year 4 of 5

Objective: Our objective was to determine effects of late-summer prescribed fire on frequency of Caucasian bluestem (Bothriochloa bladhii) in the Kansas Smoky Hills as well as changes in soil cover, botanical composition, and forage production associated with fire treatment. Study Description: The study was in Ellsworth County, KS. Eighteen one-acre plots were randomly assigned to one of three treatments: no burn, one burn (August 14, 2019), and two burns (August 14, 2019, and August 11, 2021). Soil cover, botanical composition, forage production, and Caucasian bluestem frequency were measured annually beginning in 2019. The Bottom Line: These data suggest that regular application of late-summer prescribed fire may be an effective method to reduce Caucasian bluestem frequency while improving overall grass-species richness

Impact of Obesity on Pediatric Acute Recurrent and Chronic Pancreatitis

OBJECTIVE: The aim of this study was to assess the impact of obesity on pediatric acute recurrent pancreatitis or chronic pancreatitis (CP). METHODS: We determined body mass index (BMI) status at enrollment in INSPPIRE (INternational Study group of Pediatric Pancreatitis: In search for a cuRE) cohort using CDC criteria for pediatric-specific BMI percentiles. We used the Cochran-Armitage test to assess trends and the Jonckheere-Terpstra test to determine associations. RESULTS: Of 446 subjects (acute recurrent pancreatitis, n = 241; CP, n = 205), 22 were underweight, 258 normal weight, 75 overweight, and 91 were obese. The BMI groups were similar in sex, race, and age at presentation. Hypertriglyceridemia was more common in overweight or obese. Obese children were less likely to have CP and more likely to have acute inflammation on imaging. Compared with children with normal weight, obese or overweight children were older at first acute pancreatitis episode and diagnosed with CP at an older age. Obese or overweight children were less likely to undergo medical or endoscopic treatment, develop exocrine pancreatic insufficiency, and require total pancreatectomy with islet autotransplantation. Diabetes was similar among all groups. CONCLUSIONS: Obesity or overweight seems to delay the initial acute pancreatitis episode and diagnosis of CP compared with normal weight or underweight. The impact of obesity on pediatric CP progression and severity deserves further study

Risk Factors for Rapid Progression From Acute Recurrent to Chronic Pancreatitis in Children: Report From INSPPIRE

Objective To determine the rate of progression from acute recurrent pancreatitis (ARP) to chronic pancreatitis (CP) in children and assess risk factors. Study Design Data were collected from the INternational Study group of Pediatric Pancreatitis: In search for a cuRE (INSPPIRE) cohort. Kaplan-Meier curves were constructed to calculate duration of progression from initial attack of acute pancreatitis (AP) to CP. Log-rank test was used to compare survival (non-progression) probability distribution between groups. Cox proportional hazard regression models were fitted to obtain hazard ratio (with 95% CI) of progression for each risk variable. Results Of 442 children, 251 had ARP, 191 CP. The median time of progression from initial attack of AP to CP was 3.79 years. The progression was faster in those age ≥6 years at the first episode of AP compared to those age <6 years (median time to CP: 2.91 vs 4.92 years; p=0.01). Children with pathogenic PRSS1 variants progressed more rapidly to CP compared to children without PRSS1 variants (median time to CP: 2.52 vs 4.48 years; p=0.003). Within six years after the initial AP attack, cumulative proportion with exocrine pancreatic insufficiency (EPI) was 18.0% (95% CI: 12.4%, 25.6%); diabetes mellitus was 7.7% (95% CI: 4.2%, 14.1%). Conclusions Children with ARP rapidly progress to CP, EPI and diabetes. The progression to CP is faster in children who were ≥6 years at the first episode of AP or with pathogenic PRSS1 variants. The factors that impact the aggressive disease course in childhood warrant further investigation

Pancreas Divisum in Pediatric Acute Recurrent and Chronic Pancreatitis: Report From INSPPIRE

The significance of pancreas divisum (PD) as a risk factor for pancreatitis is controversial. We analyzed the characteristics of children with PD associated with acute recurrent or chronic pancreatitis to better understand its impact. Patients and Methods: We compared children with or without PD in the well-phenotyped INSPPIRE (INternational Study group of Pediatric Pancreatitis: In search for a cuRE) cohort. Differences were analyzed using 2-sample t test or Wilcoxon rank sum test for continuous variables, Pearson χ2 or Fisher exact test for categorical variables. Results: PD was found in 52 of 359 (14.5%) subjects, a higher prevalence than the general population (∼7%). Females more commonly had PD (71% vs. 55%; P=0.02). Children with PD did not have a higher incidence of mutations in SPINK1, CFTR, CTRC compared with children with no PD. Children with PD were less likely to have PRSS1 mutations (10% vs. 34%; P<0.01) or a family history of pancreatitis (P<0.05), and more likely to have hypertriglyceridemia (11% vs. 3%; P=0.03). Children with PD underwent significantly more endoscopic procedures and pancreatic sphincterotomy. Patients with PD had fewer attacks of acute pancreatitis (P=0.03) and were less likely to develop exocrine pancreatic insufficiency (P=0.01). Therapeutic endoscopic retrograde cholangiopancreatography was considered most helpful if pancreatic duct was impacted with stones (83% helpful). Conclusions: PD is likely a risk factor for acute recurrent pancreatitis and chronic pancreatitis in children that appears to act independently of genetic risk factors. Patients with PD and stones obstructing the pancreatic duct benefit most from therapeutic endoscopic retrograde cholangiopancreatography

Web-based Cognitive-behavioral Intervention for Pain in Pediatric Acute Recurrent and Chronic Pancreatitis: Protocol of a Multicenter Randomized Controlled Trial from the Study of Chronic Pancreatitis, Diabetes and Pancreatic Cancer (CPDPC)

Introduction Abdominal pain is common and is associated with high disease burden and health care costs in pediatric acute recurrent and chronic pancreatitis (ARP/CP). Despite the strong central component of pain in ARP/CP and the efficacy of psychological therapies for other centralized pain syndromes, no studies have evaluated psychological pain interventions in children with ARP/CP. The current trial seeks to 1) evaluate the efficacy of a psychological pain intervention for pediatric ARP/CP, and 2) examine baseline patient-specific genetic, clinical, and psychosocial characteristics that may predict or moderate treatment response. Methods This single-blinded randomized placebo-controlled multicenter trial aims to enroll 260 youth (ages 10–18) with ARP/CP and their parents from twenty-one INSPPIRE (INternational Study Group of Pediatric Pancreatitis: In search for a cuRE) centers. Participants will be randomly assigned to either a web-based cognitive behavioral pain management intervention (Web-based Management of Adolescent Pain Chronic Pancreatitis; WebMAP; N = 130) or to a web-based pain education program (WebED; N = 130). Assessments will be completed at baseline (T1), immediately after completion of the intervention (T2) and at 6 months post-intervention (T3). The primary study outcome is abdominal pain severity. Secondary outcomes include pain-related disability, pain interference, health-related quality of life, emotional distress, impact of pain, opioid use, and healthcare utilization. Conclusions This is the first clinical trial to evaluate the efficacy of a psychological pain intervention for children with CP for reduction of abdominal pain and improvement of health-related quality of life. Findings will inform delivery of web-based pain management and potentially identify patient-specific biological and psychosocial factors associated with favorable response to therapy

Effective methods to increase independent reading stamina and motivation for the reluctant reader

A six-week study was conducted in a seventh grade reading class with 12 students who were identified as reading at least two years below grade level. A literature review showed a strong link between independent reading commitment and academic achievement. It also revealed motivation and stamina for independent reading can be significantly enhanced by teachers who provide access to book choice, instruction and personal guidance in self-selecting books, and opportunities for collaboration. During the study, students were taught strategies for book selection, provided time and one-on-one support for independent reading during class, and expected to read independently at home. Data collection included interest inventories, teacher observations, and student reflections. Results of the study showed improvement in the areas of reading motivation and stamina, with a marked increase in student confidence regarding ability to choose books
