Factors Associated with Growth in a Cohort of Children with Complex Biventricular Congenital Heart Disease.

OBJECTIVES: To evaluate patterns and determinants of longitudinal growth among children requiring complex biventricular repair for congenital heart disease, as well as to assess for associations of growth with early feeding modality, comorbidities, postoperative complications, and socioeconomic characteristics. STUDY DESIGN: A single-institution retrospective cohort study was performed in children born February 1999 to March 2009 with complex congenital heart disease who underwent biventricular repair before age 4 years, defined by Risk Adjustment in Congenital Heart Surgery-1 category 3-5. Clinical characteristics, height, weight, and body mass index (BMI) from ages 2-12 years were collected by chart review. Neighborhood-level socioeconomic data were identified using a geographic information system approach. The adjusted association of covariates with growth outcomes was estimated using multivariable linear regression models using generalized estimating equations. RESULTS: Compared with population growth curves, the cohort (n = 150) trended toward early decrease in age-adjusted weight and height. Early tube feeding was significantly associated with decreased BMI before adolescence (-0.539; 95% CI -1.02, -0.054; P = .029). In addition, other clinical and perioperative characteristics had significant associations with growth, including low birth weight, preoperative tube feeds, need for multiple bypass runs, and diagnosis of feeding disorder. CONCLUSIONS: Early childhood growth in children with complex biventricular repair may be impaired. Early tube feeding was associated with decreased BMI over the course of early childhood, which may indicate a need for continued close nutrition follow-up and support even beyond the duration of tube feeds.

Teaching pediatric cardiology fellows to communicate serious news: a pilot study.

BACKGROUND: Pediatric cardiology fellows often deliver serious news to families. Effective clinician-patient communication is the basis of strong therapeutic relationships and improves health outcomes, increases patient adherence, and enhances patient satisfaction. Communication training improves physicians' communication skills, ability to deliver serious news, and meet the informational and emotional needs of patients and family members. However, there is little data surrounding pediatric cardiology fellows competencies or training in communication skills. METHODS: Pediatric cardiology fellows participated in a 3-hour communication training session. The session used VitalTalk methodology and was facilitated by two VitalTalk facilitators. Fellows spent 1 h learning the skills of delivering serious news and responding to emotion and 2 h in role play with standardized actors followed by a brief group wrap-up activity. Participants took an anonymous, electronic pre- and post-survey and an 8-month follow-up survey via REDCap. Participants were asked about their preparedness and comfort performing certain communication skills and leading challenging conversations specific to pediatric cardiology. Response options used a combination of 0 (low comfort/preparedness) to 100 (high comfort/preparedness) point scales and multiple choice. RESULTS: 9 fellows participated in the training and 100% completed all three surveys. Eight were first-year fellows and 1 was a third-year fellow. Finding the right words, balancing honesty with hope, and clinical and prognostic uncertainty were the top three factors that contributed to making conversations difficult. Following the course, there was a significant increase in fellow preparedness to communicate a new diagnosis of congenital heart disease, discuss poor prognoses, check understanding, and respond to emotion and an increase in fellow comfort responding to emotions. Four fellows reported using the skills from this training course in various clinical settings at 8-month follow up. CONCLUSIONS: Communicating serious news effectively is a skill that can be learned in a sustainable way and is essential in the field of pediatric cardiology. Our study demonstrates that an interactive, VitalTalk course can improve preparedness and comfort to deliver serious news in a cohort of pediatric cardiology trainees. Future studies are needed to evaluate translation of skills to clinical practice and durability of these skills in larger cohorts.

External Disruption of Ocular Development in Utero.

The intricate steps of human ocular embryology are impacted by cellular and genetic signaling pathways and a myriad of external elements that can affect pregnancy, such as environmental, metabolic, hormonal factors, medications, and intrauterine infections. This review focuses on presenting some of these factors to recognize the multifactorial nature of ocular development and highlight their clinical significance. This review is based on English-language articles sourced from PubMed, Web of Science, and Google Scholar; keywords searched included "ocular development in pregnancy," "ocular embryology," "maternal nutrition," "ophthalmic change," and "visual system development." While some animal models show the disruption of ocular embryology from these external factors, there are limited post-birth assessments in human studies. Much remains unknown about the precise mechanisms of how these external factors can disrupt normal ocular development in utero, and more significant research is needed to understand the pathophysiology of these disruptive effects further. Findings in this review emphasize the importance of additional research in understanding the dynamic association between factors impacting gestation and neonatal ocular development, particularly in the setting of limited resources.

Ophthalmology Departments Remain Among the Least Diverse Clinical Departments at United States Medical Schools.

PURPOSE: The current demographics of the ophthalmology workforce do not reflect the diverse United States population, which has implications for addressing health disparities. The demographics of ophthalmology department faculty may influence the recruitment of underrepresented students into the field. This study sought to determine how the racial and ethnic demographics of ophthalmology department faculty compare with those of other clinical departments at United States medical schools. DESIGN: Secondary data analysis of medical school faculty demographic data from the 2019 American Association of Medical Colleges (AAMC) Faculty Roster. PARTICIPANTS: Clinical faculty and department chairs at United States medical schools. METHODS: We analyzed the racial and ethnic demographics of clinical department faculty and department chairpersons using data from the 2019 AAMC Faculty Roster. We calculated the proportion of underrepresented minority (URM) faculty in ophthalmology and in 17 other clinical departments. We analyzed these data for statistically significant differences between ophthalmology and other clinical departments. In addition, we compared the percentage of URM ophthalmology faculty with the proportion of URM persons among graduating United States medical students and in the United States population using data from the Medical School Graduation Questionnaire and the United States census, respectively. MAIN OUTCOME MEASURES: The proportion of URM persons, defined as Black, Hispanic or Latino, Native American, or Native Hawaiian or Pacific Islander among clinical faculty and department chairs. RESULTS: Ophthalmology faculty are less racially and ethnically diverse than graduating medical students and the general United States population. When compared with 17 other clinical departments, ophthalmology has the third-lowest proportion of URM faculty, with only radiology and orthopedic surgery having a smaller proportion of URM faculty. These differences were statistically significant in most departments (12 of 18). No statistically significant difference was found in the proportion of URM department chairs in ophthalmology compared with most other clinical departments, although the absolute number of URM chairs in ophthalmology is low at only 8 chairpersons. CONCLUSIONS: More work must be done to increase the recruitment of URM physicians into ophthalmology faculty positions to obtain parity with other clinical departments and with the diverse patient populations that physicians serve.

Ophthalmic Medication Expenditures and Out-of-Pocket Spending: An Analysis of United States Prescriptions from 2007 through 2016.

PURPOSE: To estimate temporal trends in total and out-of-pocket (OOP) expenditures for ophthalmic prescription medications among adults in the United States. DESIGN: Retrospective, longitudinal cohort study. PARTICIPANTS: Participants in the 2007 through 2016 Medical Expenditure Panel Survey (MEPS) 18 years of age or older. The MEPS is a nationally representative survey of the noninstitutionalized, civilian United States population. METHODS: We estimated trends in national and per capita annual ophthalmic prescription expenditures by pooling data into 2-year cycles and using weighted linear regressions. We also identified characteristics associated with greater total or OOP expenditures with multivariate weighted linear regression. Costs were adjusted to 2016 United States dollars using the gross domestic product price index. MAIN OUTCOME MEASURES: Trends in total and OOP annual expenditures for ophthalmic medications from 2007 through 2016 as well as factors associated with greater expenditures. RESULTS: From 2007 through 2016, 9989 MEPS participants (4.2%) reported ophthalmic medication prescription use. Annual ophthalmic medication use increased from 10.0 to 12.2 million individuals from 2007 and 2008 through 2015 and 2016. In this same period, national expenditures for ophthalmic medications increased from $3.39 billion to $6.08 billion and OOP expenditures decreased from $1.34 to $1.18 billion. Per capita expenditure increased from $338.72 to $499.42 (P < 0.001), and per capita OOP expenditure decreased from $133.48 to $96.67 (P < 0.001) from 2007 and 2008 through 2015 and 2016, respectively. From 2015 through 2016, dry eye (29.5%) and glaucoma (42.7%) medications accounted for 72.2% of all ophthalmic medication expenditures. Patients who were older than 65 years (P < 0.001), uninsured (P < 0.001), and visually impaired (P < 0.001) were significantly more likely to have greater OOP spending on ophthalmic medications. CONCLUSIONS: Total ophthalmic medication expenditure in the United States increased significantly over the last decade, whereas OOP expenses decreased. Increases in coverage, copayment assistance, and use of expensive brand drugs may be contributing to these trends. Policy makers and physicians should be aware that rising overall drug expenditures ultimately may increase indirect costs to the patient and offset a decline in OOP prescription drug spending.

Genetics of vascular malformation and therapeutic implications.

PURPOSE OF REVIEW: Vascular malformations (VaMs) are a consequence of disrupted morphogenesis that may involve arterial, capillary, venous, or lymphatic endothelium alone or in a combination. VaMs can have serious health impacts, leading to life-threatening conditions sometimes. Genetic mutations affecting proliferation, migration, adhesion, differentiation, and survival of endothelial cells, as well as integrity of extracellular matrix are believed to be the pathogenesis of these disorders. Here, we present an updated review of genetic mutations and potential therapeutic targets for VaMs. RECENT FINDINGS: Increased number of genetic mutations have been discovered in vascular anomalies via targeted deep sequencing. When a genetic defect is identified, it often presents in only a small percentage of cells within the malformation. In addition, mutations within the same gene may result in different clinical phenotypes. Management of VaMs can be challenging depending on the severity and functional impairment associated. There are no standard treatment algorithms available to date for VaMs, therefore the disorder has significant unmet clinical needs. Currently, the focus of therapeutic development is to target constitutively activated intracellular signaling pathways resulted from genetic mutations. SUMMARY: Knowledge about the genetic mutations and altered signaling pathways related to VaMs have improved our understanding about the pathogenesis of vascular anomalies and provided insights to the development of new targeted therapies.

Erosive pustular dermatosis of the scalp in an adolescent with near-total hair regrowth: Case report and review of the literature.

Erosive pustular dermatosis of the scalp (EPDS) is an uncommon chronic inflammatory response to scalp trauma that usually resolves with cicatricial alopecia. It most commonly affects elderly patients with a history of actinic damage. Herein, we describe a 16-year-old girl with acrofacial dysostosis type 1 presenting after surgery with crusting purulent scalp lesions, whose clinical presentation and histopathologic findings were consistent with EPDS. A review of the literature on EPDS in children is also detailed.

Corneal hysteresis and anterior segment optical coherence tomography anatomical parameters in primary angle closure suspects.

IMPORTANCE: Corneal hysteresis (CH) is a dynamic marker of structural and functional changes in the cornea associated with intraocular pressure (IOP) and central corneal thickness, but its utility in assessing primary angle closure suspects (PACS) has not been fully elucidated. BACKGROUND: This study assesses if anterior segment measurements correlate with CH in PACS patients. DESIGN: IRB-approved retrospective review of imaging and records at a university practice. PARTICIPANTS: Sixty-three eyes from 37 patients diagnosed as PACS, without other ocular pathology. METHODS: Every eye underwent measurements including: ocular response analyzer (ORA), anterior segment optical coherence tomography (OCT) and a clinical evaluation. ORA measurements were correlated with other anatomic parameters using a mixed effects multivariable linear regression framework. MAIN OUTCOME MEASURES: ORA measurements included: CH, corneal resistance factor, Goldmann IOP (IOPg ) and corneal compensated IOP (IOPcc ). Anterior segment OCT measurements included: central corneal thickness (CCTOCT ), nasal and temporal peripheral corneal thicknesses (PCT1 and PCT2), anterior chamber depth (ACD), nasal angle to temporal angle distance (ATA) and temporal and nasal angle measurements. Clinical measurements included: central corneal thickness via pachymetry, IOP measured by Goldmann applanation, axial length by A-scan ultrasound and spherical equivalent. RESULTS: CH was negatively correlated with IOPcc, and ACD CH was positively correlated with CCTOCT , CCTp , CRF, PCT1 and PCT2. Females were found to have lower CH. In multivariable regression controlling for gender, CCT, PCT, IOP and ACD, no correlation was seen between CH and anatomic measurements. CONCLUSIONS AND RELEVANCE: CH values in PACS do not correlate with anterior segment anatomy.

Incremental Revisions across the Life Span of Ophthalmic Devices after Initial Food and Drug Administration Premarket Approval, 1979-2015.

PURPOSE: To characterize the frequency, nature, and regulatory mechanisms by which ophthalmic devices are iteratively modified after initial Food and Drug Administration (FDA) Premarket Approval (PMA). DESIGN: Retrospective cross-sectional analysis using publicly available FDA data. PARTICIPANTS: Ophthalmic devices initially approved via the FDA's PMA pathway between January 1, 1979 and December 31, 2015. METHODS: We used the FDA's PMA Database to identify and characterize initial approvals and subsequent postmarket modifications to Class III ophthalmic devices. The FDA Recalls Database was used to identify associated safety events. MAIN OUTCOME MEASURES: Median iterated life span (timespan across which modifications occurred after initial PMA) and median number of supplements approved per device, by device type, and overall, stratified by regulatory pathway and modification type. RESULTS: Between 1979 and 2015, the FDA approved 168 original ophthalmic devices via the PMA pathway and 2813 subsequent modifications. More than one third (n = 64; 38%) of original approvals were intraocular lenses. Overall, devices underwent a median of 11 postmarket modifications (interquartile range [IQR], 3-24.8) across a median 10.0-year iterated life span (IQR, 4.1-16.7). The majority of devices (n = 144; 86%) underwent more than 1 postapproval modification, including more than 1 design modification (n = 84; 50%). The median number of changes altering device design or labeling was 3.5 (IQR, 1-9). Although manufacturing alterations (n = 834 of 2813; 30%) were the most frequent type of revision, changes involving device design (n = 667; 24%) and labeling (n = 417; 15%) were common. Recalled devices underwent more frequent postapproval modifications per year (median, 1.4; IQR, 0.7-2.3; mean, 1.5; 95% confidence interval, 1.1-1.9) in the period preceding recall than did nonrecalled devices (median, 0.5; IQR, 0.2-1.1; mean, 0.8; 95% confidence interval, 0.7-1.0) across their market approval period (P < 0.001). CONCLUSIONS: Most ophthalmic devices approved via the FDA's PMA pathway have undergone extensive revisions, including serial design and labeling changes, since their initial approvals, often without supporting clinical data. Ophthalmologists should take into consideration that cumulative revisions may render the clinical evidence that supported an original FDA approval less relevant to newer device models.

Irreversible Blindness Following Periocular Autologous Platelet-Rich Plasma Skin Rejuvenation Treatment.

A 49-year-old woman developed acute visual loss in the right eye following bilateral cosmetic platelet-rich plasma injections to rhytids in the glabellar region. External exam showed skin necrosis in the region over the right rhytids and restricted right ocular motility. Dilated fundus exam was significant for ophthalmic artery occlusion. Imaging revealed right eye extraocular muscle ischemia and optic nerve infarction, along with right frontal, parietal, and occipital lobe infarction. Work-up for thromboembolic and vascular etiologies were negative. To our knowledge, this is the first case reported of extensive ischemia following autologous platelet-rich plasma therapy.

Efficacy of the Amsler Grid Test in Evaluating Glaucomatous Central Visual Field Defects.

PURPOSE: To investigate the efficacy of the Amsler grid test in detecting central visual field (VF) defects in glaucoma. DESIGN: Prospective, cross-sectional study. PARTICIPANTS: Patients with glaucoma with reliable Humphrey 10-2 Swedish Interactive Threshold Algorithm standard VF on the date of enrollment or within the previous 3 months. METHODS: Amsler grid tests were performed for each eye and were considered "abnormal" if there was any perceived scotoma with missing or blurry grid lines within the central 10 degrees ("Amsler grid scotoma"). An abnormal 10-2 VF was defined as ≥3 adjacent points at P < 0.01 with at least 1 point at P < 0.005 in the same hemifield on the pattern deviation plot. Sensitivity, specificity, and positive and negative predictive values of the Amsler grid scotoma area were calculated with the 10-2 VF as the clinical reference standard. Among eyes with an abnormal 10-2 VF, regression analyses were performed between the Amsler grid scotoma area and the 10-2 VF parameters (mean deviation [MD], scotoma extent [number of test points with P < 0.01 in total deviation map] and scotoma mean depth [mean sensitivity of test points with P < 0.01 in total deviation map]). MAIN OUTCOME MEASURES: Sensitivity, specificity, and positive and negative predictive values of the Amsler grid scotoma area. RESULTS: A total of 106 eyes (53 patients) were included (mean ± standard deviation age, 24-2 MD and 10-2 MD = 66±12 years, -9.61±8.64 decibels [dB] and -9.75±9.00 dB, respectively). Sensitivity, specificity, and positive and negative predictive values of the Amsler grid test were 68%, 92%, 97%, and 46%, respectively. Sensitivity was 40% in eyes with 10-2 MD better than -6 dB, 58% in eyes with 10-2 MD between -12 and -6 dB, and 92% in eyes with 10-2 MD worse than -12 dB. The area under the receiver operating characteristic curve of the Amsler grid scotoma area was 0.810 (95% confidence interval, 0.723-0.880, P < 0.001). The Amsler grid scotoma area had the strongest relationship with 10-2 MD (quadratic R(2)=0.681), followed by 10-2 scotoma extent (quadratic R(2)=0.611) and 10-2 scotoma mean depth (quadratic R(2)=0.299) (all P < 0.001). CONCLUSIONS: The Amsler grid can be used to screen for moderate to severe central vision loss from glaucoma.

Effect of supine body position on central corneal thickness.

BACKGROUND: To evaluate the effect of supine body position on central corneal thickness (CCT) in open-angle glaucoma patients and in healthy subjects. DESIGN: A cross-sectional study at a university eye clinic. PARTICIPANTS: Twenty-three subjects were recruited in each group, for a total of 46 patients. METHODS: CCT was measured using an ultrasound pachymeter in each subject. Three consecutive measurements in each eye were first taken in the sitting position, and repeated after 10 min and 30 min in a supine position. Results were analyzed using mixed model repeated measures, which adjusted for age, gender and laterality of eyes. MAIN OUTCOME MEASURES: CCT RESULTS: In healthy subjects, CCT decreased with supine positioning at 10 min (mean = -5.2 µm, P = 0.0043) and at 30 min (mean = -6.5 µm, P < 0.0001). In the glaucoma group, CCT decreased with supine positioning at 10 min (mean = -6.7 µm, P = 0.0043) and at 30 min (mean = -10.2 µm, P < 0.0001). There was no statistically significant difference between the CCT at 10 min supine and at 30 min supine in the healthy subjects (P = 0.37) and glaucoma patients (P = 0.14). CCT was shown to decrease linearly over time (P < 0.0001), and the slopes were not statistically different between groups (P = 0.40). CONCLUSIONS: CCT is a dynamic measurement that can be influenced by body position. It decreases linearly in the first 30 min of supine positioning at a similar rate in both open angle glaucoma patients and in healthy subjects.

Development and Evaluation of Aeyeconsult: A Novel Ophthalmology Chatbot Leveraging Verified Textbook Knowledge and GPT-4.

OBJECTIVE: There has been much excitement on the use of large language models (LLMs) such as ChatGPT in ophthalmology. However, LLMs are limited in that they are trained on unverified information and do not cite their sources. This paper highlights a new methodology to create a generative AI chatbot to answer eye care related questions which uses only verified ophthalmology textbooks as data and cites its sources. SETTING: Yale School of Medicine Department of Ophthalmology and Visual Science. DESIGN/METHODS: Aeyeconsult, an ophthalmology chatbot, was developed using GPT-4 (the LLM used to power the publicly available chatbot ChatGPT-4), LangChain, and Pinecone. Ophthalmology textbooks were processed into embeddings and stored in Pinecone. User queries were similarly converted, compared to stored embeddings, and GPT-4 generated responses. The interface was adapted from public code. Both Aeyeconsult and ChatGPT-4 were tested on the same 260 questions from OphthoQuestions.com, with the first response from Aeyeconsult and ChatGPT-4 recorded as the answer. RESULTS: Aeyeconsult outperformed ChatGPT-4 on the OKAP dataset, with 83.4% correct answers compared to 69.2% (p = 0.0118). Aeyeconsult also had fewer instances of no answer and multiple answers. Both systems performed best in General Medicine, with Aeyeconsult achieving 96.2% accuracy. Aeyeconsult's weakest performance was in Clinical Optics at 68.1%, but it still outperformed ChatGPT-4 in this category (45.5%). CONCLUSION: LLMs may be useful in answering ophthalmology questions but their trustworthiness and accuracy is limited due to training on unverified internet data and lack of source citation. We used a new methodology, using verified ophthalmology textbooks as source material and providing citations, to mitigate these issues, resulting in a chatbot more accurate than ChatGPT-4 in answering OKAPs style questions.

Domestic Violence-Related Ocular Injuries Among Adult Patients: Data from the Nationwide Emergency Department Sample, 2008-2017.

PURPOSE: To investigate domestic violence (DV)-related ocular injuries among adult emergency department (ED) patients in the US. METHODS: This was a retrospective, cross-sectional study of patients with a diagnosis of DV and diagnosis of ocular injury in the Nationwide Emergency Department Sample (NEDS) from 2008-2017. We identified patient- and hospital-level variables associated with DV-related ocular injuries. We calculated annual incidence rates using US Census data. Adjusting for inflation using the Consumer Price Index, we calculated mean and total charges. RESULTS: From 2008-2017, there were 26,215 ED visits for ocular injuries related to DV with an average incidence of 1.09 per 100,000 adult population (female patients, 84.5%; mean age [SE], 34.3 [0.2]). DV-related ocular injuries were most prevalent among patients in the lowest income quartile (39.1%) and on Medicaid (37.4%). Most ED visits presented to metropolitan teaching (55.4%), non-trauma (46.7%), and south regional (30.5%) hospitals. The most common ocular injury was contusion of eye/adnexa (61.1%). The hospital admission rate was 5.2% with a mean hospital stay of 2.9 [0.2]. The inflation-adjusted mean cost for medical services was $38,540 [2,310.8] per encounter with an average increase of $2,116 per encounter, annually. The likelihood of hospital admission increased for patients aged ≥60 years old, on Medicare, and with open globes or facial/orbital fractures (all p < .05). CONCLUSION: Contusion of the eye/adnexa was the most common ocular injury among patients with DV-related ED visits. To better facilitate referrals to social services, ophthalmologists should utilize DV screenings, especially towards women and patients of less privileged socioeconomic status.

EKG Acquisition Curriculum for Pediatric Trainees.

OBJECTIVES: Pediatric residency trainees interface with electrocardiograms (EKG) as part of routine clinical care. Depending on workflow and availability of support staff, trainees may be required to obtain EKGs on patients, though training on this skill varies. Our intervention seeks to train incoming pediatric residents on obtaining EKGs from pediatric patients and identifying common problems that may result in acquisition of low-fidelity EKGs. METHODS: A team of physicians, EKG technicians, and simulation educators designed a 30-min didactic and experiential learning opportunity for incoming pediatric trainees held prior to their start of clinical responsibilities. During the session, trainees were introduced to the basics of EKG acquisition and common quality issues that arise. Afterwards, they practiced placing EKG leads on a mannequin and a live model. A pre- and post-session survey was utilized to assess the session's utility and participant's learning. RESULTS: The intervention was perceived as a valuable experience by participants over the course of 2 years. We found increased participant comfort with performing and troubleshooting EKGs (P<.001). There was a 33% improvement in quality assessment of EKG rhythm strips after the session (P<.001). CONCLUSION: Given the importance of EKGs to the care of pediatric patients, it is essential that pediatricians receive adequate training in acquiring and assessing EKG quality. This intervention was deemed to be highly useful with a demonstrated improvement in EKG troubleshooting skills among first year pediatric residents. This session improves learner comfort with essential clinical responsibilities and identification of low-quality EKGs that often warrant repeat testing.

Factors Associated With Visual Impairment Among Adults With a History of Criminal Justice Involvement.

The purpose of this study was to investigate the prevalence of and factors associated with visual impairment among adults with a history of criminal justice involvement (CJI). This retrospective, cross-sectional study reviewed adult respondents from the 2015-2018 National Survey on Drug Use and Health. We analyzed sociodemographic and health characteristics to determine factors associated with visual impairment among adults with and without a history of CJI. In this national, population-based study, we found similar rates of visual impairment among adults with and without CJI (5.7% vs. 4.2%, p < .001). However, adults with CJI were more likely to report visual impairment at a younger age. Among adults with CJI, visual impairment was associated with female sex, older age, Black/African American race, less education, lower income, and chronic health conditions (including diabetes, heart disease, respiratory illness, mental health symptoms, and hearing impairment). CJI in the past year (probation [adjusted odds ratio, AOR, 0.70; 95% confidence interval, CI, 0.53-0.93]; one arrest [AOR, 1.47; 95% CI, 1.14-1.89]; two or more arrests [AOR, 1.73; 95% CI, 1.29-2.33]) was uniquely associated with visual impairment among adults with a CJI history (p < .05 for all relationships). Research, screening, and treatment for visual impairment should include those with justice involvement to improve health equity.

Epidemiologic trends of domestic violence-related ocular injuries among pediatric patients: data from the Nationwide Emergency Department Sample 2008-2017.

PURPOSE: To study the epidemiology of all domestic violence (DV)-related ocular injuries among pediatric emergency department (ED) patients in the United States. METHODS: This is a retrospective, cross-sectional study of isolated children (<18 years of age) with a diagnosis of DV and primary or secondary diagnosis of ocular injuries in the Nationwide Emergency Department Sample, 2008-2017. We calculated annual incidence of DV-related ocular injuries and prevalence by demographic variables, including age, sex, and income quartile. Median charges, median length of inpatient hospital stay, and factors associated with hospitalization were also measured. RESULTS: From 2008 to 2017, there were 4,125 ED encounters, with an average incidence of 0.56 per 100,000 population (males, 50.0%; mean age [SE], 9.2 [0.3]). Patients in the lowest income quartile (42.6%) and with Medicaid insurance (63.2%) were the most prevalent. The most common known perpetrator was a family member (29.4%). Most ED encounters took place at southern regional (28.6%), metropolitan teaching (67.1%) and designated trauma hospitals (57.8%). Contusion of the eye/adnexa and being struck by or against an object were the most common ocular diagnosis and known mechanism of injury, respectively. An estimated 12.4% of patients were admitted with a median hospital stay of 4 (IQR, 2-6). Median charges during the study period were $27,415.10 (IQR, $13,142.70-$54,454.90). CONCLUSIONS: DV-related ocular injuries were most prevalent among patients with a low socioeconomic status. Given the historical underreporting of DV, future studies are warranted to identify more specific social determinants of health that contribute to such presentations.

Kahook Dual Blade versus Trabectome (KVT): Comparing Outcomes in Combination with Cataract Surgery.

Purpose: To compare the safety and efficacy of Kahook Dual Blade (KDB) versus Trabectome with cataract surgery in reducing intraocular pressure (IOP) and medications used by patients with glaucoma. Methods: Retrospective chart review comparing eyes after KDB or Trabectome with cataract surgery at 2 academic centers. Surgical success was defined as IOP <21 mmHg with ≥20% IOP reduction at post-operative month 12 (POM12). Changes in IOP, number of glaucoma medications, and adverse events were assessed. Results: Ninety eyes in the KDB group and 125 eyes in the Trabectome group were included. Mean changes in IOP at POM12 were -1.9 ± 4.9 mmHg (11.2%, P = 0.002) in the KDB group and -3.5 ± 5.5 mmHg (19.1%, P < 0.001) in the Trabectome group, without a significant difference between the groups (P = 0.20). Mean change in glaucoma medications at POM12 was -0.8 ± 1.5 in the KDB group (58%, P < 0.001) and -0.3 ± 1.3 (38%, P = 0.003) in the Trabectome group, with KDB having a greater decrease in medications (P = 0.02). The percentage of eyes achieving success was 30% for the KDB group and 54% for the Trabectome group (P = 0.01). Hyphema was the most common complication, with an incidence of 3% for the KDB group and 14% for the Trabectome group (P = 0.01). Conclusion: KDB or Trabectome with cataract surgery is safe and effective at lowering IOP and medication burden, with KDB resulting in a greater reduction in medications and Trabectome more frequently achieving success with an increased incidence of hyphema. Considering the study's limitations, the outcomes were similar.

A robotic system for automated genetic manipulation and analysis of Caenorhabditis elegans.

The nematode Caenorhabditis elegans is one of the most widely studied organisms in biology due to its small size, rapid life cycle, and manipulable genetics. Research with C. elegans depends on labor-intensive and time-consuming manual procedures, imposing a major bottleneck for many studies, especially for those involving large numbers of animals. Here, we describe a general-purpose tool, WormPicker, a robotic system capable of performing complex genetic manipulations and other tasks by imaging, phenotyping, and transferring C. elegans on standard agar media. Our system uses a motorized stage to move an imaging system and a robotic arm over an array of agar plates. Machine vision tools identify animals and assay developmental stage, morphology, sex, expression of fluorescent reporters, and other phenotypes. Based on the results of these assays, the robotic arm selectively transfers individual animals using an electrically self-sterilized wire loop, with the aid of machine vision and electrical capacitance sensing. Automated C. elegans manipulation shows reliability and throughput comparable with standard manual methods. We developed software to enable the system to autonomously carry out complex protocols. To validate the effectiveness and versatility of our methods, we used the system to perform a collection of common C. elegans procedures, including genetic crossing, genetic mapping, and genomic integration of a transgene. Our robotic system will accelerate C. elegans research and open possibilities for performing genetic and pharmacological screens that would be impractical using manual methods.
