In-hospital outcomes in people with autism and epilepsy - A population-based study.

Autism is a common comorbid diagnosis in those with epilepsy. Understanding the health needs and outcomes in patients with this dual diagnosis is important for optimizing healthcare outcomes. We compared hospital-level variables amongst patients with co-occurring autism and epilepsy, to those with epilepsy alone. Non-elective hospital admissions amongst patients with epilepsy alone and co-occurring autism and epilepsy were identified in the 2003-14 National Inpatient Sample (NIS) using previously validated ICD-9-CM case definitions. One patient with co-occurring epilepsy and autism was matched to three epilepsy patients for age and sex. Multinomial logistic regressions were performed to examine outcomes of interest. Compared to those with epilepsy alone (n = 27,762), patients with autism and epilepsy (n = 9254) had a higher odds of transfer to another facility (OR = 1.09, p = 0.048), in-hospital mortality (OR = 1.36, p = 0.011), longer mean length of stay (5.63 days vs. 5.12 days, p < 0.0001), and septicemia (4.21 % vs. 3.08 %, p < 0.0001). Distributions of demographics, insurance type, socioeconomic status, and comorbidities significantly differed between both groups. Our findings demonstrate that patients with comorbid autism and epilepsy are a unique population with health outcomes significantly differing from those with epilepsy alone. Given the effect that dual diagnosis has on hospital trajectory, focused treatment plans must be adopted to optimize care and hospital outcomes in these patients.

Single-cell transcriptomic analysis of corneal organoids during development.

Corneal organoids are useful tools for disease modeling and tissue transplantation; however, they have not yet been well studied during maturation. We characterized human iPSC-derived corneal organoids at 1, 2, 3, and 4 months of development using single-cell RNA sequencing to determine the cellular heterogeneity at each stage. We found pluripotent cell clusters committed to epithelial cell lineage at 1 month; early corneal epithelial, endothelial, and stromal cell markers at 2 months; keratocytes as the largest cell population at 3 months; and a large epithelial cell population at 4 months. We compared organoid to fetal corneal development at different stages and found that 4-month organoids closely resemble the corneal cellular complexity of the fetal (16 post conception week) and adult cornea. Using RNA velocity trajectory analysis, we found that less differentiated cells appear to give rise to corneal epithelial cells during development.

Comparing vagus nerve stimulation and resective surgery outcomes in patients with co-occurring autism and epilepsy to patients with epilepsy alone: A population-based study.

Autism and epilepsy commonly co-occur. Understanding trends in healthcare utilization and in-hospital outcomes amongst patients with autism and epilepsy can help optimize care and reduce costs. We compared hospital outcomes amongst patients with autism and epilepsy to those with epilepsy alone undergoing vagus nerve stimulation (VNS) and resective/disconnective surgery. Differences in discharge status, in-hospital mortality, mean length of stay (LOS), cost and surgical/medical complications were examined. Elective surgical admissions amongst patients with epilepsy alone and co-occurring autism and epilepsy were identified in the 2003-14 National Inpatient Sample (NIS) using previously validated ICD-9-CM case definitions. One patient with co-occurring epilepsy and autism was matched to three epilepsy patients for age, sex and (1) VNS and (2) resective/disconnective surgery. Multinomial logistic regressions were performed to examine the outcomes of interest. Data were collected on: (1) VNS-52 (mean age: 12.79 ± 1.03; 19.27% female) hospital admissions in persons with comorbid autism and epilepsy, 156 (mean age: 12.84 ± 0.71; 19.31% female) matched controls with epilepsy alone; (2) resective/disconnective surgery-113 (mean age: 12.99 ± 0.84; 24.55% female) with comorbid autism and epilepsy, 339 (mean age: 13.37 ± 0.68; 23.86% female) matched controls with epilepsy alone. Compared to patients with epilepsy alone, patients with autism and epilepsy who underwent either surgery showed no differences for in-hospital mortality, discharge status, mean LOS, hospitalization cost, and surgical/medical complications. Our study shows the feasibility and safety of epilepsy VNS and resective surgery in those with ASD do not differ with those with epilepsy alone, contrary to the prevalent safety concerns of epilepsy surgery in patients with ASD.

PNP Hydrogel Prevents Formation of Symblephara in Mice After Ocular Alkali Injury.

PURPOSE: To create an alkali injury symblephara mouse model to study conjunctival fibrosis pathophysiology and test polymer nanoparticle (PNP) hydrogel as a preventative therapeutic. METHODS: Mice were injured using NaOH-soaked filter paper to determine the optimal NaOH concentration to induce the formation of symblephara. Injured mice were observed for 7 days to detect the formation of symblephara. Forniceal shortening observed on hematoxylin and eosin (H&E)-stained tissue sections was used as a symblephara marker. Alpha-smooth muscle actin (α-SMA) expression, Masson's trichrome assay, and periodic acid-Schiff (PAS) staining were used to determine myofibroblast expression, collagen deposition, and goblet cell integrity. PNP hydrogel, with multivalent, noncovalent interactions between modified biopolymers and nanoparticles, was applied immediately after alkali injury to determine its ability to prevent the formation of symblephara. RESULTS: Forniceal shortening was observed in H&E images with 1N NaOH for 2 minutes after 7 days without globe destruction. PNP hydrogel prevented forniceal shortening after alkali injury as observed by H&E histology. α-SMA expression and collagen deposition in eye tissue sections were increased in the fornix after injury with 1N NaOH compared with uninjured controls. PNP hydrogel treatment immediately after injury reduced α-SMA expression and collagen deposition in the forniceal region. Mucin-secreting goblet cells stained with PAS were significantly lower in alkali-injured and PNP hydrogel-treated conjunctivas than in uninjured control conjunctivas. CONCLUSIONS: We observed that 1N NaOH for 2 minutes induced maximal forniceal shortening and symblephara in mice. PNP hydrogel prevented forniceal shortening and conjunctival fibrosis after injury. This first murine model for symblephara will be useful to study fibrosis pathophysiology after conjunctival injury and to determine therapeutic targets for cicatrizing diseases. TRANSLATIONAL RELEVANCE: This mouse model of symblephara can be useful for studying conjunctival scarring disease pathophysiology and preventative therapeutics. We tested PNP hydrogel, which prevented the formation of symblephara after injury.

Breast Arterial Calcification in the Mammogram Report: The Patient Perspective.

OBJECTIVE: The purpose of this study was to determine patient attitudes about mammographic reporting of breast arterial calcification (BAC), result communication, and action. SUBJECTS AND METHODS: A self-administered survey was created for this project and was offered to mammography patients presenting for screening or diagnostic mammography over a 1-month period. RESULTS: Among those who accepted questionnaires, 61.8% (419/678) responded with varying response rates to specific questions. A large percentage (95.8% [363/379]) preferred to have BAC reported. All 107 patients who were unaware of a personal history of heart disease wanted notification about BAC. There were 552 communication responses from 354 women. Among these responses, 62.5% (345/552) indicated a preference for notification from the radiology department by letter or telephone call. Among those who had a single preference, 76.6% (180/235) preferred notification by the radiology department in the patient results letter or by telephone call. Of those who chose one action option, 87.4% (181/207) indicated that they would undergo coronary artery CT before making a decision. Among those who selected multiple options, 53.2% (272/511) expressed a desire for coronary artery CT before making a decision. Age, level of education, and race were not associated with patients' attitudes toward BAC. CONCLUSION: Patients had an overwhelming preference to be informed about BAC found at mammography. Given the ease of reporting BAC and the calls by preventive cardiologists to have the information, the widespread adoption of BAC reporting on mammography reports can promote prevention, diagnosis, and if needed, treatment of cardiovascular disease.
