A Medical Student Initiative to Enhance the Pediatric Hemodialysis Experience.

BACKGROUND: Children and young adults receiving hemodialysis (HD) face unique challenges including frequent school absenteeism, psychosocial issues, and social isolation, placing them at risk for decreased academic achievement and health literacy. OBJECTIVE: To address this, we implemented the Child and Adolescent Motivation and Enrichment Program (CHAMP) at Holtz Children's Hospital in Miami, FL. The objective of this study is to describe the organizational structure and program design of CHAMP and provide preliminary program opinions. METHODS: Medical students served as longitudinal one-on-one mentors to patients receiving HD. Face-to-face intervention, books, board games, and electronic tablets were used to enhance patients' educational and recreational experience. We surveyed participating patients, medical students, and unit nurses regarding their opinions of CHAMP. KEY RESULTS: Patients responded to a series of questions on a Likert scale scored from 1 to 5 and reported the highest scores on questions pertaining to having fun with mentors (mean = 4.88), enjoying mentor visits (mean = 4.78), and learning during visits (mean = 3.88). Mentors reported the highest level of agreement (mean = 4.82) that CHAMP helped them gain empathy for patients with chronic and/or special health care needs. Nurses scored highly on the point that "overall, the program was useful and helped the patient" (mean = 6.86 of a possible 7). CONCLUSION: CHAMP is an academic and psychosocial enrichment program for children and adolescents receiving HD. The program is regarded highly by participating patients, medical students, and unit nurses. Patients report enjoying and learning from mentor sessions, whereas nurses report improved interactions with patients. Medical students who participate as mentors also gain important exposure to the field of pediatric nephrology. The program design as described herein positions CHAMP for replication at academic medical centers nationwide, allowing for optimization of the health and well-being of the pediatric HD population.

To address this, we implemented the Child and Adolescent Motivation and Enrichment Program, a longitudinal mentorship program pairing medical students as one-on-one mentors to patients undergoing HD. Preliminary results from this program demonstrate satisfaction and enjoyment by participating patients, medical students, and dialysis unit nurses.

Long-term Persistence of Allosensitization After Islet Allograft Failure.

BACKGROUND: Allosensitization has been reported after discontinuation of immunosuppression following graft failure in islet transplantation (ITx) recipients, though duration of its persistence is unknown. METHODS: We evaluated 35 patients with type 1 diabetes who received ITx, including 17 who developed graft failure (ITx alone, n = 13; ITx plus bone marrow-derived hematopoietic stem cells, n = 4) and 18 with persistent graft function. Panel-reactive antibody (PRA) was measured yearly for the duration of graft function within 1 y after graft failure at enrollment and yearly thereafter. RESULTS: In ITx alone graft failure patients, 61% (8/13) were PRA-positive at 6 y postgraft failure, and 46% (6/13) developed donor-specific anti-HLA antibodies (DSA to 2 ± 1 donors) during follow-up. The degree of sensitization was variable (cPRA ranging between 22% and 100% after graft failure). Allosensitization persisted for 7-15 y. Three subjects (3/13) were not allosensitized. In ITx plus bone marrow-derived hematopoietic stem cell recipients, cPRA-positivity (88%-98%) and DSA positivity persisted for 15 y in 75% (3/4) of subjects. CONCLUSIONS: Allosensitization was minimal while subjects remained on immunosuppression, but after discontinuation of immunosuppressive therapy, the majority of subjects (77%) became allosensitized with persistence of PRA positivity for up to 15 y. Persistence of allosensitization in this patient population is of clinical importance as it may result in longer transplant waiting list times for identification of a suitable donor in the case of requiring a subsequent transplant.

Impact of the coronavirus pandemic on pediatric eye-related emergency department services.

Literature describing the trends and utilization of pediatric eye-related emergency department (ED) visits is limited. We performed a retrospective cohort study of 311 pediatric patients visiting Bascom Palmer Eye Institute (BPEI) ED between March and May 2020 to quantify the effect of the coronavirus (COVID-19) on ophthalmology care utilization. In our study, pediatric ED visits declined by half at the onset of the pandemic in March. The number of visits reached the lowest point in early April and increased to 48% of the pre-COVID volume by the end of May. Despite changes in volume, patient demographics and clinical diagnoses were relatively consistent throughout the pandemic.

Pediatric Eye Care: We Cannot Lose Sight of Its Importance despite the COVID-19 Pandemic.

Visual impairment affects over 19 million children globally and, if left untreated, can result in significant ocular morbidity. Due to the treatable nature of many childhood visual disturbances, pediatric vision screening is essential for optimization of health and developmental outcomes. The coronavirus disease 2019 (COVID-19) pandemic has inevitably disrupted the provision of routine pediatric health care as evidenced by reduced adherence to vaccination schedules. Further, the home environment, which many children have now become confined to, is known to pose risk for eye trauma which may result in irreversible vision loss. Therefore, it is imperative for pediatricians and pediatric ophthalmologists to focus on eye health and safety, despite the backdrop of a global pandemic.

Telehealth Training Is Essential to Care for Underserved Populations: a Medical Student Perspective.

Telehealth is an area of medicine which has magnified the ability to treat patients remotely. Presently the education of medical professionals pertaining to the value, use, and implementation of telehealth is not adequate to harness the potential of available technologies. Patients engaging in telehealth experience time and cost savings, improved disease management through remote monitoring programs, and high-quality care regardless of geographic location. Despite this, medical education has been slow to evolve. It is therefore imperative that medical curricula incorporate training for this rapidly advancing mode of healthcare delivery to enable students to best care for their future patient population.

Pediatric Nonceliac Gluten Sensitivity: A Gluten-related Disorder Treatment Center Experience.

OBJECTIVE: The aim of the study was to identify the prevalence and clinical characteristics of children with nonceliac gluten sensitivity (NCGS) presenting to a tertiary care center specialized for evaluation of gluten-related disorders. METHODS: The medical records of all patients aged 0 to 18 years who presented to our center over a 4-year period (July 2013-June 2018) and consented to participate in our research registry were reviewed. Patients meeting the clinical criteria for NCGS were reviewed in detail. RESULTS: Among 500 pediatric patients who volunteered to participate in the registry during the study period, we identified 26 (5.2%) with NCGS. Both gastrointestinal and extraintestinal symptoms associated with gluten ingestion were common with abdominal pain (57.7%), bloating (53.9%), rash (53.9%), diarrhea/loose stool (42.3%), and emotional/behavioral issues (42.3%) emerging as the predominant complaints. In addition, children with NCGS demonstrated a high personal history (61.5%) and family history (61.5%) of concomitant allergic/atopic disease. CONCLUSIONS: Even within our highly specialized population of patients with a suspected gluten-related disorder, pediatric NCGS is relatively uncommon. The estimated prevalence and clinical features mirror those previously reported in a similarly highly selective population of adults. In the absence of celiac disease, clinical suspicion for NCGS should arise in a child with gastrointestinal and/or extraintestinal complaints alleviated with gluten removal and considered in symptomatic patients with associated allergic/atopic disease. Proper and adequate exclusion of celiac disease and other potential causes of the clinical complaints is essential to justify adoption of the gluten-free diet according to an appropriate stringency and with dietitian supervision to avoid nutritional deficiencies.

Blood-brain barrier and intestinal epithelial barrier alterations in autism spectrum disorders.

BACKGROUND: Autism spectrum disorders (ASD) are complex conditions whose pathogenesis may be attributed to gene-environment interactions. There are no definitive mechanisms explaining how environmental triggers can lead to ASD although the involvement of inflammation and immunity has been suggested. Inappropriate antigen trafficking through an impaired intestinal barrier, followed by passage of these antigens or immune-activated complexes through a permissive blood-brain barrier (BBB), can be part of the chain of events leading to these disorders. Our goal was to investigate whether an altered BBB and gut permeability is part of the pathophysiology of ASD. METHODS: Postmortem cerebral cortex and cerebellum tissues from ASD, schizophrenia (SCZ), and healthy subjects (HC) and duodenal biopsies from ASD and HC were analyzed for gene and protein expression profiles. Tight junctions and other key molecules associated with the neurovascular unit integrity and function and neuroinflammation were investigated. RESULTS: Claudin (CLDN)-5 and -12 were increased in the ASD cortex and cerebellum. CLDN-3, tricellulin, and MMP-9 were higher in the ASD cortex. IL-8, tPA, and IBA-1 were downregulated in SCZ cortex; IL-1b was increased in the SCZ cerebellum. Differences between SCZ and ASD were observed for most of the genes analyzed in both brain areas. CLDN-5 protein was increased in ASD cortex and cerebellum, while CLDN-12 appeared reduced in both ASD and SCZ cortexes. In the intestine, 75% of the ASD samples analyzed had reduced expression of barrier-forming TJ components (CLDN-1, OCLN, TRIC), whereas 66% had increased pore-forming CLDNs (CLDN-2, -10, -15) compared to controls. CONCLUSIONS: In the ASD brain, there is an altered expression of genes associated with BBB integrity coupled with increased neuroinflammation and possibly impaired gut barrier integrity. While these findings seem to be specific for ASD, the possibility of more distinct SCZ subgroups should be explored with additional studies.
