Using a Mixed-method Approach to Develop a Transition Program for Young Adults With Inflammatory Bowel Disease.

BACKGROUND: Although transition guidelines have been specified in pediatric inflammatory bowel disease (IBD), few IBD centers implement these into standard care. We describe a mixed qualitative and quantitative process of developing a needs-based transition program for adolescents and young adults with IBD. METHODS: We enrolled 29 adolescents with IBD, 8 young adults with IBD in adult care, 14 pediatric gastroenterologists, and 58 adult gastroenterologists to provide input into barriers to successful transition, essential patient competencies, and key targets of clinical intervention. RESULTS: The availability and expertise of adult gastroenterologists in childhood-onset IBD were identified by pediatric providers as primary barriers to health care transfer. A medical summary containing pertinent health information was identified by adult providers as instrumental to assume patient care post transfer. Young adults with IBD identified self-advocacy, education on insurance basics, and peer mentoring as essential targets of transition support and preparation in pediatric care. Findings were used to develop educational materials, a portable medical summary, a referral database of adult gastroenterologists, and a young adult clinic geared towards transition planning. CONCLUSION: Involving key patient and provider stakeholders in the development of a transition program is aimed at ensuring that the individual needs of patients and their families are met. Collaboration between pediatric and adult providers is also intended to facilitate a seamless continuum from pediatric to adult health care services. Efforts to evaluate the impact of such programming on self-management in adult care are needed.

An unknown nocturnal call type in the Mariana Archipelago.

In spring/summer of 2018 and 2021, the Pacific Islands Fisheries Science Center Cetacean Research Program deployed drifting acoustic recorders in the U.S. Exclusive Economic Zones surrounding the Mariana Archipelago. Manual assessments revealed a low-frequency (median 473-554 Hz), short-duration (median 0.596 s), stereotypic tonal nocturnal call throughout the Mariana Archipelago. Based on time of year, spatiotemporal patterns, clear division among calls (i.e., no chorusing), comparisons with known vocalizations of whales, turtles, and fish, and presence of Bryde's whale calls, and because the call has not been detected elsewhere, we hypothesize this 500-Hz pulsed call is produced by Bryde's whales (Balaenoptera brydei).

Inhibiting TGF-ß activity improves respiratory function in mdx mice.

Respiratory function is the main cause of mortality in patients with Duchenne muscular dystrophy (DMD). Elevated levels of TGF-ß play a key role in the pathophysiology of DMD. To determine whether therapeutic attenuation of TGF-ß signaling improves respiratory function, mdx mice were treated from 2 weeks of age to 2 months or 9 months of age with either 1D11 (a neutralizing antibody to all three isoforms of TGF-ß), losartan (an angiotensin receptor antagonist), or a combination of the two agents. Respiratory function was measured in nonanesthetized mice by plethysmography. The 9-month-old mdx mice had elevated Penh values and decreased breathing frequency, due primarily to decreased inspiratory flow rate. All treatments normalized Penh values and increased peak inspiratory flow, leading to decreased inspiration times and breathing frequency. Additionally, forelimb grip strength was improved after 1D11 treatment at both 2 and 9 months of age, whereas, losartan improved grip strength only at 2 months. Decreased serum creatine kinase levels (significant improvement for all groups), increased diaphragm muscle fiber density, and decreased hydroxyproline levels (significant improvement for 1D11 only) also suggested improved muscle function after treatment. For all endpoints, 1D11 was equivalent or superior to losartan; coadministration of the two agents was not superior to 1D11 alone. In conclusion, TGF-ß antagonism may be a useful therapeutic approach for treating DMD patients.

Acoustic classification of false killer whales in the Hawaiian islands based on comprehensive vocal repertoire.

Use of underwater passive acoustic datasets for species-specific inference requires robust classification systems to identify encounters to species from characteristics of detected sounds. A suite of routines designed to efficiently detect cetacean sounds, extract features, and classify the detection to species is described using ship-based, visually verified detections of false killer whales (Pseudorca crassidens). The best-performing model included features from clicks, whistles, and burst pulses, which correctly classified 99.6% of events. This case study illustrates use of these tools to build classifiers for any group of cetacean species and assess classification confidence when visual confirmation is not available.

Acoustic differentiation and classification of wild belugas and narwhals using echolocation clicks.

Belugas (Delphinapterus leucas) and narwhals (Monodon monoceros) are highly social Arctic toothed whales with large vocal repertoires and similar acoustic profiles. Passive Acoustic Monitoring (PAM) that uses multiple hydrophones over large spatiotemporal scales has been a primary method to study their populations, particularly in response to rapid climate change and increasing underwater noise. This study marks the first acoustic comparison between wild belugas and narwhals from the same location and reveals that they can be acoustically differentiated and classified solely by echolocation clicks. Acoustic recordings were made in the pack ice of Baffin Bay, West Greenland, during 2013. Multivariate analyses and Random Forests classification models were applied to eighty-one single-species acoustic events comprised of numerous echolocation clicks. Results demonstrate a significant difference between species' acoustic parameters where beluga echolocation was distinguished by higher frequency content, evidenced by higher peak frequencies, center frequencies, and frequency minimums and maximums. Spectral peaks, troughs, and center frequencies for beluga clicks were generally > 60 kHz and narwhal clicks < 60 kHz with overlap between 40-60 kHz. Classification model predictive performance was strong with an overall correct classification rate of 97.5% for the best model. The most important predictors for species assignment were defined by peaks and notches in frequency spectra. Our results provide strong support for the use of echolocation in PAM efforts to differentiate belugas and narwhals acoustically.

Headlines and hashtags: communicating science during an outbreak.

Science and medical professionals are often looked to as experts in the event of a health crisis, but relatively few have received formal training in science communication. We provide a brief review of the current outbreak situation and suggestions for engaging in reliable, effective science communication online.

Impact of raising serum myoglobin on resuscitation of trauma patients with high injury severity score (ISS).

INTRODUCTION: Recent studies recommend limiting the amount of crystalloid perfused during resuscitation for trauma patients. Severely injured patients sustain extensive muscle damage with subsequent high serum myoglobin levels precipitating acute renal injury if not treated immediately. To timely identify patients at risk of acute renal injury, we proposed determining the strength of the correlation between the American College of Surgeons-defined injury severity score with serum and urine myoglobin level in the early hours of arrival to the emergency department to determine the patient at higher risk of raising serum myoglobin level and subsequent renal injury. METHOD: A retrospective analysis was conducted at a 400-bed community teaching hospital with a level 2 trauma section and annual admission of 750-800 patients using the data in the trauma registry (2010-2017). Patients with an injury severity score of 15 or above were selected, and Student t test and Pearson correlation 2-tailed analysis were used to identify the relationship with serum myoglobin. RESULT: There were 306 patients total, with 200 men (70.3%) and 106 women (29.7%) and a mean age of 60.64 (SD = 23.6) (range 18-96) years. The mean injury severity score was 22.3 (SD = 8.5) (range 16-75). The median level of serum myoglobin in the first 24 hours of admission was 848.56 ng/mL (range 22-11,197). There was a strong and significant correlation between the 2 variables (r = 0.397, P < .0001). CONCLUSION: The appearance of urine myoglobin with serum level of 39 ng/mL suggests that with higher injury severity score, the potential for acute kidney injury is likely and should be addressed early in the patient management.

Incidence of Dysplasia in Obese vs Nonobese Patients With Nondysplastic Barrett Esophagus.

Background: Obesity is a known independent risk factor for both Barrett esophagus and esophageal adenocarcinoma. However, data about the effect of obesity on the risk of progression from nondysplastic Barrett esophagus to dysplasia or esophageal adenocarcinoma are lacking. The aim of this study was to evaluate whether obese patients with nondysplastic Barrett esophagus had a higher incidence of dysplasia development during routine surveillance than nonobese patients. Methods: In a retrospective review, 1,999 patients who had a first diagnosis of nondysplastic Barrett esophagus made by esophagogastroduodenoscopy (EGD) at a single community hospital were tracked to their surveillance EGD 3 to 5 years later to evaluate for dysplasia (low grade, high grade, or adenocarcinoma). We compared the incidence of dysplasia development in obese patients (body mass index [BMI] ≥30 kg/m2) with nonobese patients (BMI <30 kg/m2). Results: The sample population included 1,019 obese patients (51.0%) and 980 nonobese patients (49.0%) with nondysplastic Barrett esophagus. Their mean age was 56.5 ± 11.6 years, 1,228 (61.4%) were male, and 1,853 (92.7%) were Caucasian. At surveillance endoscopy performed at a mean follow-up of 3.7 years after their first EGD, 51 obese patients (incidence of 15.3 cases per 1,000 person-years, 95% confidence interval [CI], 11.5-19.9) and 15 nonobese patients (incidence of 4.6 cases per 1,000 person-years, 95% CI, 2.7-7.4) had developed dysplasia (P=0.0001). Conclusion: We found a significant increase in the incidence of dysplasia development in obese patients with nondysplastic Barrett esophagus at 3- to 5-year follow-up compared to nonobese patients. This finding suggests that more frequent surveillance in obese patients with nondysplastic Barrett esophagus may be warranted for early detection of dysplasia.

Does a fracture liaison service program minimize recurrent fragility fractures in the elderly with osteoporotic vertebral compression fractures?

BACKGROUND: There is a sizable proportion of elderly, both men and women, with fragility fractures, approximately 2 million fractures per year in the United States. METHODS: A retrospective chart review of 365 patient presented between January 2012 and December 2017 with vertebral compression fractures. Pre-post study design to determine refracture between Group A (before Fracture Liaison Service (FLS)) and Group B, after. Calcium, Vitamin D, DEXA scans, FRAX scores, and refracture rates were measured. RESULTS: Mean age for group A and B were 79.0 and 74.9 years, respectively, and predominantly females. Serum calcium was higher in group B (9.51 mg/d/L versus 9.40 mg/dL) but not significant (p = 0.19). Fracture score among the groups was similar (20% versus 22%; p = 0.44). The total refracture rate for both vertebral and other fracture was significantly less in the post FLS patients, 36.5% versus 56% p-value = 0.01. CONCLUSION: FLS program benefited patients with fragility fractures by decreasing the incidence of all refracture rates.

Diabetes Management Among Arab Americans Who Sought Care at a Large Metropolitan Hospital System in Michigan.

To estimate and compare the management of diabetes among Arab, Asian, non-Hispanic Black, and non-Hispanic Whites attending a large health system in metropolitan Detroit. Data were electronically abstracted for 6622 adult patients with diabetes. Dependent variables were uptake of A1c testing and results, LDL-C testing and results, and eye examination frequency. The independent variable was race/ethnicity. Logistic regression models were used to examine the association between Arab Americans and non-Hispanic Whites for each of the dependent variables while controlling for confounders. Arab Americans were 38% more likely than non-Hispanic Whites to report an A1c > 7% (OR 1.38; 95% CI 1.03, 1.87). Arab Americans were 62% less likely to receive an eye exam compared to non-Hispanic Whites (OR 1.62; 95% CI 1.21, 2.17). Population based studies about diabetes management among Arab Americans will facilitate tailored interventions aimed at preventing/delaying diabetes complications and reducing premature mortality due to diabetes.

Screen Exposure During Daily Routines and a Young Child's Risk for Having Social-Emotional Delay.

This cross-sectional study assessed associations between social-emotional development in young children and their number of daily routines involving an electronic screen. We hypothesized children with poor social-emotional development have a significant portion of daily routines occurring with a screen. Two hundred and ten female caregivers of typically developing children 12 to 36 months old completed the Ages and Stages Questionnaire: Social-Emotional (ASQ: SE) and a media diary. Caregivers completed the diary for 1 day around 10 daily routines (Waking Up, Diapering/Toileting, Dressing, Breakfast, Lunch, Naptime, Playtime, Dinner, Bath, and Bedtime). Median number of daily routines occurring with a screen for children at risk and not at risk for social-emotional delay (as defined by the ASQ: SE) was 7 versus 5. Children at risk for social-emotional delay were 5.8 times more likely to have ≥5 routines occurring with a screen as compared to children not at risk for delay (χ12 = 9.28, N = 210, P = .002; 95% confidence interval = 1.66-20.39).
