Polysubstance use in inflammatory bowel disease is associated with increased risk of emergency department visits: a longitudinal study.

Background: Polysubstance use (PSU), the simultaneous use of 2 or more substances of abuse, is common in inflammatory bowel disease (IBD). Preliminary studies suggest it may be associated with poor outcomes. This prospective study evaluated the impact of PSU on disease activity and healthcare resource utilization in IBD. Methods: This study was conducted in a tertiary IBD center between October 29, 2015, and December 31, 2019. Participants were assessed over 2 time points (index and follow-up outpatient appointments) separated by a minimum of 6 months. Demographics, endoscopic disease activity, and surveys assessing symptoms, healthcare resource utilization and substance use (tobacco, alcohol, marijuana, cocaine, methamphetamine, heroin, opioid, or benzodiazepine) were abstracted. We identified PSU during the index appointment and computed descriptive statistics and contingency table analyses, and multivariate logistic regression models at follow up to evaluate outcomes. Results: 162 consecutively enrolled IBD patients were included. Seventy-five patients (46%) were polysubstance users at the index appointment. The most common cohorts were utilizing tobacco and alcohol (n=40) or tobacco and opioids (n=13). On bivariate and multivariate analyses, PSU during the index visit was positively associated with emergency department (ED) visits (odds ratio [OR] 2.51, 95% confidence interval [CI] 1.24-5.07; P=0.01) and negatively associated with extraintestinal manifestations (OR 0.37, 95%CI 0.18-0.74; P=0.005). Age, sex, disease activity, disease subtype and IBD-related symptoms were not associated with PSU. Conclusions: IBD patients exhibiting PSU had increased risk of future ED visits. This study highlights the risks of PSU and reinforces the importance of appropriate substance use screening.

Pyoderma Gangrenosum Is Associated With Increased Risk of Inflammatory Pouch-Related Complications: A Retrospective Cohort Study.

Background: Pyoderma gangrenosum (PG) is a rare, neutrophilic dermatosis that is a well-established extraintestinal manifestation (EIM) of inflammatory bowel disease. The clinical implications of developing PG in patients with ulcerative colitis (UC) who undergo total proctocolectomy colectomy and ileal pouch anal anastomosis (TPC-IPAA) surgery remain unknown. Methods: Study participants were selected from patients enrolled in the Carlino Family Inflammatory Bowel and Colorectal Disease Biobank between 1998 and 2021 with a pre-colectomy diagnosis of UC and who underwent TPC-IPAA surgery. A retrospective study comparing patients with PG and those without PG was performed. The outcomes measured included the development of pouchitis, pouchitis classification, presence of pouch fistula, anal fistula, anal stenosis, and pouch failure. Results: In this study, 357 IPAA patients were included, 10 of whom suffered PG. Patients with PG and without PG had similar demographics and clinical characteristics. Both groups had similar rates of pouchitis (80% in PG patients and 64% in patients without PG, P = .504). However, IPAA patients with PG had a higher risk of developing pouch fistula (50% vs 10%, P = .002), anal fistula (40% vs 12%, P = .031), and Crohn's-like disease of the pouch (70% vs 15%, P = .003) compared to patients without PG. Patients who developed PG prior to their first episode of pouchitis were more likely to eventually experience pouch failure (odds ratio: 20.7, 95% confidence interval: 3.9, 110.7, q = 0.003 after false discovery rate adjustment). Conclusions: Among UC patients who undergo TPC-IPAA surgery, the development of PG portends poor pouch outcomes and is predictive of pouch failure.

Abdominal pain is associated with an increased risk of future healthcare resource utilization in inflammatory bowel disease.

BACKGROUND: Numerous factors influence healthcare resource utilization (HRU) in inflammatory bowel disease (IBD). We previously demonstrated an association between the presence of certain IBD-related symptoms and HRU. We conducted a longitudinal study to identify the clinical variables and IBD-related symptoms predictive of HRU. METHODS: This investigation utilized clinical encounters at an IBD center within a tertiary care referral center between 10/29/2015-12/31/2019. Participants were assessed over two time points (index and follow-up office visits) separated by a minimum of 6 months. Demographics, endoscopic disease severity, totals and sub-scores of surveys assessing for IBD-related symptoms, HRU, and substance use, and IBD-related medications. HRU was defined as any IBD-related emergency room visit, hospitalization, or surgery during the 6 months prior to follow-up appointment. We identified patients exhibiting HRU (at follow-up) and computed descriptive statistics and contingency table analyses of index appointment clinical data to identify predictors of HRU. Multivariable logistic regression models were fit incorporating significant demographic and clinical factors. RESULTS: 162 consecutively enrolled IBD patients (mean age 44.0 years; 99f:63 m; 115 Crohn's disease [CD], 45 ulcerative colitis [UC], 2 indeterminate colitis) were included. 121 patients (74.7%) exhibited HRU (mean age 43.6 years; 73f:48 m; 84 CD, 36 UC, 1 IC) preceding follow-up appointment. Abdominal pain (OR = 2.18, 95% CI 1.04-4.35, p = 0.04) at the index appointment was the only study variable significantly associated with HRU on bivariate analysis (Table 1). However, none of the clinical factors evaluated in this study were independently associated with HRU in our multivariable logistic regression model. CONCLUSIONS: In this longitudinal study, abdominal pain was the only clinical variable that demonstrated an association with future HRU (even when considering other symptoms and key variables such as disease activity, IBD-medications, and psychiatric comorbidities (i.e., anxious or depressed state). These findings reinforce the importance of regularly screening for and effectively treating abdominal pain in IBD.

Salivary microRNAs in pediatric eosinophilic esophagitis.

Background: Diagnosis and management of eosinophilic esophagitis (EoE) occur via esophagogastroduodenoscopy with tissue biopsy. Objective: We sought to determine if salivary microribonucleic acid (miRNA) levels could differentiate children with EoE, serving as a noninvasive biomarker. Methods: Saliva was collected from children undergoing esophagogastroduodenoscopy (N = 291). miRNA analysis was conducted on 150 samples: EoE (n = 50), no pathologic alteration (n = 100). RNA was quantified with high throughput sequencing and aligned to build hg38 of the human genome using sequencing and alignment software. Quantile normalized levels of robustly expressed miRNAs (raw counts > 10 in 10% of samples) were compared across EoE and non-EoE groups with Wilcoxon rank sum testing. miRNA biomarker candidates were selected based on variable importance projection (VIP) scoring with partial least squared discriminant analysis (VIP > 1.5). Ability of these miRNAs to differentiate EoE status was assessed via logistic regression. Putative biologic targets for the miRNA candidates were determined in miRNA pathway analysis software. Results: Of the 56 salivary miRNAs reliably detected, miR-205-5p displayed the largest difference between EoE and non-EoE groups (V = 1623, adjusted p = 0.029). Six miRNAs (miR-26b-5p, miR-27b-3p, Let-7i-5p, miR-142-5p, miR-30a-5p, miR-205-5p) displayed elevated VIP scores (>1.5) and were able to differentiate EoE samples on logistic regression analysis with 70% sensitivity and 68% specificity. These six miRNAs demonstrated significant enrichment for gene targets involved in valine, leucine, and isoleucine biosynthesis (p = 0.0012), 2-oxycarboxylic acid metabolism (p = 0.043), and steroid hormone biosynthesis (p = 0.048). Conclusions: Salivary miRNAs represent a noninvasive, biologically relevant measure that may aid disease monitoring of EoE.

Dedicated Psychiatry Clinic for Inflammatory Bowel Disease Patients Has a Positive Impact on Depression Scores.

Background: Psychiatric disorders, including anxiety and depression, are significantly more common in patients with inflammatory bowel disease (IBD). We established an integrated psychiatry clinic for IBD patients at our tertiary center IBD clinic to provide patients with critical, but frequently unavailable, coordinated mental health services. We undertook this study to evaluate the impact of this service on psychiatric outcomes, quality of life, and symptom experience. Methods: We performed a longitudinal prospective study comparing patients who had been cared for at our integrated IBD-psychiatry clinic to those who had not. We abstracted demographic and clinical information as well as contemporaneous responses to validated surveys. Results: Thirty-six patients cared for in the IBD psychiatry clinic were compared to a control cohort of 35 IBD patients. There was a significant reduction in the Hospital Anxiety and Depression Scale (HADS) depression score over time in the study cohort (p = 0.001), though not in the HADS anxiety score. When compared to the control group, the study cohort showed a significant reduction in the HADS depression score. No significant differences were observed in the Harvey-Bradshaw Index, Simple Clinical Colitis Activity Index, or Short IBD Questionnaire. Conclusions: This is the first study to evaluate the impact of an integrated psychiatry clinic for IBD patients. Unlike their control counterparts, individuals treated in this clinic had a significant reduction in the mean HADS depression score. Larger scale studies are necessary to verify these findings. However, this study suggests that use of an integrated psychiatry IBD clinic model can result in improvement in mental health outcomes, even in the absence of significant changes in IBD activity.

Symptoms associated with healthcare resource utilization in the setting of inflammatory bowel disease.

Several symptoms have been connected to increased healthcare resource utilization (HRU) in the context of inflammatory bowel disease (IBD), including both Crohn's disease (CD) and ulcerative colitis (UC). This study was designed to investigate the prevalence of IBD-associated symptoms and to determine whether any are independently associated with HRU. We undertook a retrospective analysis of data related to consecutive IBD patient encounters from a tertiary care referral center between 1/1/2015 and 8/31/2019. Demographics, clinical activity, endoscopic severity, IBD-related symptom scores, anxiety and depression scores, and other key clinical data were abstracted. Four hundred sixty-seven IBD patients [247f.: 220 m; 315 CD, 142 UC and 11 indeterminate colitis] were included in this study. The most common symptoms were fatigue (83.6%), fecal urgency (68.2%) and abdominal pain (63.5%). Fatigue, abdominal pain, anxiety or depression, corticosteroids, and opioids were each positively associated with HRU, while NSAID and mesalamine use were inversely associated on bivariate analysis. The only factor that demonstrated a statistically significant association with HRU in the whole cohort on multivariable analysis was abdominal pain. Abdominal pain is independently associated with HRU and should be specifically screened for in IBD patients to identify individuals at risk of undergoing expensive interventions. This study also reinforces the importance of optimizing diagnostic and therapeutic management of abdominal pain in IBD.

Needs Assessment for Eosinophilic Esophagitis Education in School Nurses.

Over the past 2 decades, eosinophilic esophagitis (EoE) has become increasingly recognized as a common cause of gastrointestinal morbidity in children. A mainstay of treatment is food avoidance, which must be implemented in both the home and school settings for school-aged children. The aim of this study is to assess school nurses' familiarity with EoE with regard to food avoidance and treatment in the school setting. We conducted a 19-question online survey of 60 school nurses (elementary through high school) recruited from Dauphin, Lebanon, and Lancaster Counties in Pennsylvania. Results indicated that 62% of respondents were familiar with EoE. However, only 22% felt comfortable distinguishing between symptoms of EoE and food-dependent anaphylaxis. Almost all respondents (97%) were interested in learning more about EoE. We report significantly increased familiarity with food-dependent anaphylaxis in comparison with EoE among school nurses. There is an interest and need for increasing education on EoE.

Polysubstance use in inflammatory bowel disease.

OBJECTIVES: We aimed to evaluate the incidence, predisposing factors and impacts of polysubstance use (PSU) (ie, the concurrent use or abuse of two or more drugs or substances) in inflammatory bowel disease (IBD). METHODS: Data of patients enrolled between 1 January 2015 and 31 August 2019 from a single tertiary care referral center were retrospectively collected. Patients' baseline and clinical characteristics and their antidepressant and/or anxiolytic medications were abstracted. Associations between PSU and patients' characteristics were analyzed. Multivariate logistic regression models were fit, incorporating significant clinical factors. RESULTS: Altogether 315 patients with IBD (166 women, 149 men; 214 with Crohn's disease and 101 ulcerative colitis) were enrolled. Of them, 66 (21.0%) exhibited PSU (CD 21.5%, UC 19.8%); 37.5% had moderate to severe disease activity, 34.3% with extraintestinal manifestations (EIM), 41.6% with an anxious or depressed state and 69.8% had used healthcare resources in the prior 12 months. Moreover, 71.2% used two substances, while 27.3% used three substances. In the total cohort, EIM (odds ratio [OR] 1.97, 95% confidence interval [CI] 1.14-3.34, P = 0.019) and antidepressant or anxiolytic use (OR 2.51, 95% CI 1.45-4.39, P < 0.001) were positively associated with PSU on multivariate analysis. PSU was associated with increased rate of IBD-associated imaging (57.6% vs 47.0%, P < 0.05). CONCLUSIONS: PSU is common in IBD. EIM, antidepressant and/or anxiolytic use and imaging studies were independently associated with PSU. This study reinforces the importance of screening patients with IBD for substance use, particularly those with EIM and using antidepressants and/or anxiolytics.

The Impact of COVID-19 Pandemic on Prevalence of Diabetic Ketoacidosis at Diagnosis of Type 1 Diabetes: A Single-Centre Study in Central Pennsylvania.

Objective: We conducted this study to investigate whether the COVID-19 pandemic impacted the rate of DKA and previously identified risk factors in children presenting with T1D. Methods: We performed an extension of a retrospective analysis of all paediatric patients (age ≤ 18) newly diagnosed with T1D within a tertiary care referral centre between 01/01/2017 and 09/14/2020. Demographics, insurance coverage and clinical documents 30 days before their T1D diagnosis were abstracted to assess for symptoms at diagnosis, laboratory values (blood glucose, HbA1c, venous pH and bicarbonate) and any healthcare encounters within 30 days of their diagnosis of T1D. Results: 412 patients with T1D [171 F:241 M; 370 pre-COVID era:42 post-COVID era] were included. The percentages of DKA diagnoses at admission were very similar between the pre-COVID and post-COVID groups (47% vs. 48%), as were the severity (13% vs. 14% mild DKA; 33% vs. 31% moderate or severe DKA). Conclusion: There were no fluctuations in the rate of DKA among paediatric patients newly diagnosed with T1D throughout the coronavirus pandemic in central Pennsylvania.

Prevalence and factors associated with diabetic ketoacidosis at diagnosis of type 1 diabetes: A report from a tertiary medical center in Central Pennsylvania.

Objective: To explore the rate and factors associated with diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes (T1D) in a single tertiary medical centre in Central Pennsylvania. Methods: Retrospective chart review of all individuals ≤ 18 years of age who were diagnosed with T1D (N = 350) at the Penn State Hershey Pediatric Diabetes Clinic from January 2017 to December 2019. We report logistic regression models for DKA at diagnosis of T1D for age, gender, race/ethnicity, BMI percentile, health insurance, outcome of any healthcare encounter 30 days prior to T1D diagnosis, HbA1c level, altered mental status at diagnosis, and diagnosis of autism spectrum disorder and a multivariable logistic regression model including all aforementioned variables. Results: Of the 350 newly diagnosed children with T1D from 2017 to 2019, 161/350 (46%) presented in DKA. Among patients with DKA, there were 45 (28%) in mild DKA and 116 (72%) in moderate/severe DKA, which represents 13% and 33% of all patients diagnosed with T1D, respectively. Variables associated with increased risk of DKA at presentation of T1D included age (<3 or 9-13), BMI percentile (<3% or > 97%), no referral during preceding healthcare encounter, HbA1c level and altered mental status. In a multivariable model, age (<3 or 9-13), no referral during preceding healthcare encounter, HbA1c level and altered mental status were associated with DKA at presentation, whereas gender, race/ethnicity, BMI percentile, health insurance and autism spectrum disorder diagnosis were not. Discussion: Our study notes an overall higher rate of DKA at diagnosis (46%) compared to the SEARCH study (approximately 30%) but a lower rate compared to a recent study in Colorado children (58%).

Prevention of diabetic ketoacidosis at diagnosis of type 1 diabetes: Are certified athletic trainers an untapped resource?

Aims: To assess the knowledge of certified athletic trainers (ATs) on the presenting signs and symptoms of type 1 diabetes (T1D). Methods: We conducted a 31-question survey of secondary school ATs recruited from the National Athletic Training Association that established demographic information, knowledge of presenting signs and symptoms of T1D, and previous personal or professional exposure to individuals with T1D. We report descriptive statistics and univariate analyses evaluating the characteristics associated with T1D knowledge. We then report a multivariable model incorporating age, gender, years of experience and education level with T1D knowledge as the dependent variable. Results: 128 participants (92f:34m) met inclusion criteria and were included in this study. The majority of participants correctly identified frequent thirst (96.1%, n = 123) and frequent urination (85.9%, n = 110) as common presenting signs and symptoms of T1D, while fewer participants identified weight gain (58.6%, n = 75) or joint pain (39.1%, n = 50) as incorrect presenting signs and symptoms of T1D. Participants with over ten years of experience or previous exposure to individuals with T1D had increased T1D knowledge. Participants with advanced education (Master's degree or Doctorate) had no statistically significant difference in T1D knowledge compared to those with a Bachelor's degree. The only factor that demonstrated a significant association with T1D knowledge on multivariable analysis was the female gender. Conclusions: Educational awareness campaigns of T1D symptoms to reduce the rate of DKA at diagnosis of T1D have never included ATs. This study illustrates the importance of targeting future educational interventions on newly trained ATs.

Efficacy of a student-led community contact tracing program partnered with an academic medical center during the coronavirus disease 2019 pandemic.

PURPOSE: Contact tracing has proven successful at controlling coronavirus 2019 (COVID-19) globally, and the Center for Health Security has recommended that the United States add 100,000 contact tracers to the current workforce. METHODS: To address gaps in local contact tracing, health professional students partnered with their academic institution to conduct contact tracing for all COVID-19 cases diagnosed onsite, which included identifying and reaching their contacts, educating participants, and providing social resources to support effective quarantine and isolation. RESULTS: From March 24 to May 28, 536 laboratory-confirmed COVID-19 cases were contacted and reported an average of 2.6 contacts. Contacts were informed of their exposure, asked to quarantine, and monitored for the onset of symptoms. Callers reached 94% of cases and 84% of contacts. Seventy-four percent of cases reported at least one contact. Household members had higher rates of reporting symptoms (odds ratio, 1.65; 95% confidence interval, 1.19-2.28). The average test turnaround time decreased from 21.8 days for the first patients of this program to 2.3 days on the eleventh week. CONCLUSIONS: This provides evidence for the untapped potential of community contact tracing to respond to regional needs, confront barriers to effective quarantine, and mitigate the spread of COVID-19.

Cannabis and Cannabis Derivatives for Abdominal Pain Management in Inflammatory Bowel Disease.

For centuries, cannabis and its components have been used to manage a wide variety of symptoms associated with many illnesses. Gastrointestinal (GI) diseases are no exception in this regard. Individuals suffering from inflammatory bowel disease (IBD) are among those who have sought out the ameliorating properties of this plant. As legal limitations of its use have eased, interest has grown from both patients and their providers regarding the potential of cannabis to be used in the clinical setting. Similarly, a growing number of animal and human studies have been undertaken to evaluate the impact of cannabis and cannabinoid signaling elements on the natural history of IBD and its associated complications. There is little clinical evidence supporting the ability of cannabis or related products to treat the GI inflammation underlying these disorders. However, 1 recurring theme from both animal and human studies is that these agents have a significant impact on several IBD-related symptoms, including abdominal pain. In this review, we discuss the role of cannabis and cannabinoid signaling in visceral pain perception, what is currently known regarding the efficacy of cannabis and its derivatives for managing pain, related symptoms and inflammation in IBD, and what work remains to effectively utilize cannabis and its derivatives in the clinical setting.

Implementation and Process of a COVID-19 Contact Tracing Initiative: Leveraging Health Professional Students to Extend the Workforce During a Pandemic.

BACKGROUND: The Centers for Disease Control and Prevention recommends aggressive contact tracing to control the COVID-19 pandemic. In this work, we (1) describe the development of a COVID-19 contact tracing initiative that includes medical, nursing, and public health students, and is led by clinicians and infectious disease epidemiologists within our health system, and, (2) articulate process steps for contact tracing including workflows and telephone scripts, and, (3) highlight the key challenges and strategies to overcome these challenges. METHODS: A single academic institution-based contact tracing initiative was rapidly scaled to 110 health professional students, four physicians, two epidemiologists, and a research team. Following training, students called patients who were COVID-19 positive and the individuals they were in contact with to ensure proper isolation and quarantine measures. Students also assisted those who faced barriers to quarantine. IMPLICATIONS: In total, between March 24 and May 28 - this initiative completed contact tracing for 536 confirmed cases, which resulted in the identification of 953 contacts. We aim to disseminate this process, including telephone scripts and workflow, to other health systems for use in their initiatives to respond to the COVID-19 pandemic and future public health emergencies.

Separating Putative Pathogens from Background Contamination with Principal Orthogonal Decomposition: Evidence for Leptospira in the Ugandan Neonatal Septisome.

Neonatal sepsis (NS) is responsible for over 1 million yearly deaths worldwide. In the developing world, NS is often treated without an identified microbial pathogen. Amplicon sequencing of the bacterial 16S rRNA gene can be used to identify organisms that are difficult to detect by routine microbiological methods. However, contaminating bacteria are ubiquitous in both hospital settings and research reagents and must be accounted for to make effective use of these data. In this study, we sequenced the bacterial 16S rRNA gene obtained from blood and cerebrospinal fluid (CSF) of 80 neonates presenting with NS to the Mbarara Regional Hospital in Uganda. Assuming that patterns of background contamination would be independent of pathogenic microorganism DNA, we applied a novel quantitative approach using principal orthogonal decomposition to separate background contamination from potential pathogens in sequencing data. We designed our quantitative approach contrasting blood, CSF, and control specimens and employed a variety of statistical random matrix bootstrap hypotheses to estimate statistical significance. These analyses demonstrate that Leptospira appears present in some infants presenting within 48 h of birth, indicative of infection in utero, and up to 28 days of age, suggesting environmental exposure. This organism cannot be cultured in routine bacteriological settings and is enzootic in the cattle that often live in close proximity to the rural peoples of western Uganda. Our findings demonstrate that statistical approaches to remove background organisms common in 16S sequence data can reveal putative pathogens in small volume biological samples from newborns. This computational analysis thus reveals an important medical finding that has the potential to alter therapy and prevention efforts in a critically ill population.
