High Rates of Eye Surgery Cancellation in Veterans Related to Mental Health.

INTRODUCTION: Approximately 9 million veterans receive health care at the Veterans Health Administration, many of whom have psychiatric illnesses. The military continues to have higher rates of psychiatric illness compared to the civilian population. Having a diagnosis such as posttraumatic stress disorder or depression may create challenges in using health care services, such as surgery. The aim of this study was to evaluate eye surgery cancellation, risk factors for cancellation, and areas for intervention within the VA. MATERIALS AND METHODS: This was a single-center retrospective cohort study. The Veteran Health Information Systems and Technology Architecture were queried to identify all surgical requests at the West Los Angeles VA in 2019. Data collection included sociodemographic information and comorbid medical conditions, including psychiatric illness. Exploratory analyses using univariate logistic regression were used to evaluate factors associated with surgery cancellation. RESULTS: A total of 1,115 surgical requests were identified with a cancellation rate of 23.7% (n = 270). Sociodemographic factors were similar between those with completed and cancelled surgery. However, having a psychiatric diagnosis correlated with surgery cancellation. For all subspecialties, patients with schizophrenia were more likely to have cancellation (odds ratio [OR], 2.53, P = .04). For retina surgery, patients with posttraumatic stress disorder were more likely to have cancellation (OR, 4.23, P = .01). Glaucoma patients with anxiety (OR, 5.78, P = .05) and depression (OR, 4.05, P = .04) were more likely to have cancellation. CONCLUSIONS: There was a significant amount of eye surgery cancellations in veterans with variation by subspecialty and comorbid conditions. Having a psychiatric illness was correlated with increased rates of surgery cancellation amongst veterans. Areas to improve surgical utilization include risk stratification and increased support of vulnerable patients before surgery.

Prevalence, Clinical and Imaging Characteristics of Superior Ophthalmic Vein Periphlebitis in Thyroid Eye Disease.

INTRODUCTION: To determine the prevalence, clinical features, and radiographic findings of superior ophthalmic vein periphlebitis (SOVP) in thyroid eye disease (TED). METHODS: Patients with a clinical diagnosis of thyroid eye disease and contrast-enhanced imaging were included. Imaging was reviewed for the presence of SOVP, and patients with SOVP were compared to those without. A random eye was determined to be the affected eye in patients without SOVP. RESULTS: A total of 212 patients met the inclusion criteria. Unilateral SOVP was identified in 4.7% of cases. There was no significant difference in age (p = 0.22), gender (p = 0.09), or disease duration (p = 0.14) between patients with and without SOVP. There was a significant (p < 0.05) difference in stage classification and clinical activity core between the groups. The affected eye in patients with SOVP had significantly (p < 0.05) greater margin reflex distance 1, degree of relative proptosis, horizontal motility restriction, and vertical motility restriction than in patients without SOVP. There was no significant difference in horizontal strabismus (p = 1.0), vertical strabismus (p = 0.87), or relative intraocular pressure (p = 0.77). On imaging, the maximal diameter of the SR and IR were found to be significantly (p < 0.05) larger in the affected eye of patients with periphlebitis; however, there was no difference in measured diameter of the medial rectus and (p = 0.30) or lateral rectus (p = 0.78). CONCLUSIONS: SOVP is an under-reported imaging finding of thyroid eye disease. It is associated with significantly greater margin reflex distance 1, relative proptosis, and motility restriction on exam as well as larger superior rectus and inferior rectus diameter on imaging. These patients tend to present in the active stage of disease with greater clinical activity score.

Neurodevelopmental Outcomes in Infants Screened for Retinopathy of Prematurity.

Importance: Preterm infants screened for retinopathy of prematurity (ROP) are at risk for heterogenous neurodevelopment outcomes that are difficult to predict. Objective: To characterize the potential association between socioeconomic and clinical risk factors and neurodevelopmental outcomes in a diverse, multicenter cohort of premature neonates screened for ROP. Design, Setting, and Participants: This was a retrospective cohort study using electronic medical records and US Census Bureau income data. This study was performed at academic (University of California, Los Angeles [UCLA] Mattel Children's Hospital and UCLA Santa Monica Hospital), community (Cedars-Sinai Medical Center), and LA county (Harbor-UCLA Medical Center) neonatal intensive care units. Participants included infants who met American Academy of Pediatrics guidelines for ROP screening and had records from at least 1 Bayley Scales of Infant and Toddler Development (BSID) neurodevelopment assessment between 0 and 36 months of adjusted age. Data analyses were conducted from January 1, 2011, to September 1, 2022. Exposures: Demographic and clinical information, proxy household income, and health insurance type were collected as risk factors. Main Outcomes and Measures: Neurodevelopmental outcomes in the cognitive, language, and motor domains measured via BSID were the primary outcomes. Results: A total of 706 infants (mean [SD] age, 28.6 [2.4] weeks; 375 male [53.1%]) met inclusion criteria. In a multivariable model, which included adjustments for birth weight, sex, insurance type, intraventricular hemorrhage (IVH), and age at assessment, public health insurance was associated with a 4-fold increased risk of moderate to severe neurodevelopmental impairment (NDI) in cognitive and language domains (cognitive, odds ratio [OR], 3.65; 95% CI, 2.28-5.86; P = 8.1 × 10-8; language, OR, 3.96; 95% CI, 2.61-6.02; P = 1.0 × 10-10) and a 3-fold increased risk in the motor domain (motor, OR, 2.60; 95% CI, 1.59-4.24; P = 1.4 × 10-4). In this adjusted model, clinical factors that were associated with an increased risk of moderate to severe NDI included lower birth weight, diagnosis of IVH, male sex, and older age at time of Bayley assessment. In unadjusted analyses, infants who received either laser or anti-VEGF treatment, compared with infants without treatment-requiring ROP, had lower BSID scores in multiple domains at 0 to 12 months, 12 to 24 months, and 24 to 36 months (DATA). In the multivariable model, treatment type was no longer associated with worse neurodevelopmental outcomes in any domain. Conclusions and Relevance: Study results suggest an association between public insurance type and NDI in a diverse population screened for ROP, indicating the complexities of neurodevelopment. This study also supports the early neurodevelopmental safety of anti-VEGF treatment, as anti-VEGF therapy was not found to be independently associated with worse NDI in any domain.

A MULTICENTER STUDY OF RETINOPATHY OF PREMATURITY FOLLOW-UP ADHERENCE.

PURPOSE: Characterize clinical and socioeconomic factors that impact follow-up to complete retinal vascularization and subsequent pediatric ophthalmology follow-up in neonates with retinopathy of prematurity. METHODS: Medical records of 402 neonates diagnosed with retinopathy of prematurity from neonatal intensive care units at the University of California, Los Angeles Mattel Children's Hospital and the University of California, Los Angeles Santa Monica Hospital, both academic medical centers, and the Harbor-University of California, Los Angeles Medical Center, a safety-net county hospital, were reviewed. Primary study outcomes were the rate of follow-up to complete retinal vascularization and adequate pediatric ophthalmology follow-up. Secondary outcome was the rate of nonretinal ocular comorbidity. RESULTS: In whole-cohort analysis, 93.6% of neonates were followed to complete retinal vascularization, and 53.5% had adequate pediatric ophthalmology follow-up. Public insurance was associated with lower rates of pediatric ophthalmology follow-up (Odds ratio 0.66, 95% confidence interval 0.45-0.98, P = 0.04). Participants screened at the academic medical center had lower rates of pediatric ophthalmology follow-up compared with the safety-net county hospital (50.7% vs. 63.5%, P = 0.034). In subgroup analysis, academic medical center participants with public insurance were less likely to have pediatric ophthalmology follow-up than safety-net county hospital participants with public insurance (36.5% vs. 63.8%, P < 0.001) or those with private insurance at the academic medical center (36.5% vs. 59.2%, P< 0.001). CONCLUSION: This study identified high follow-up rates to complete retinal vascularization, lower pediatric ophthalmology follow-up rates, and nonretinal ocular comorbidity at all hospitals. Insurance status relative to hospital type was identified as a risk factor for loss to follow-up. This demonstrates a need to further study health care disparities in retinopathy of prematurity infants.

PRENATAL MATERNAL CHARACTERISTICS ASSOCIATED WITH RETINOPATHY OF PREMATURITY.

PURPOSE: Determine whether prenatal maternal characteristics such as sociodemographic characteristics, comorbidities, or pregnancy complications affect retinopathy of prematurity (ROP) development. METHODS: Medical records of 236 mother-infant dyads from our institution were reviewed, only including dyads in which infants were born at 30 weeks gestational age or earlier. The primary outcome measure was the risk of ROP (defined Stage 1 or greater in either eye) and its association with prenatal maternal variables. RESULTS: Maternal Medicaid insurance, smoking during pregnancy, and chorioamnionitis were associated with an increased risk of ROP. For Medicaid insurance and chorioamnionitis, these risks were not appreciably altered by adjustment for potential confounders. CONCLUSION: These results suggest that several prenatal maternal factors may independently affect the risk of ROP in preterm infants. Validation of our findings could aid in the identification of infants at high risk for ROP based on prenatal clinical features.

Orbital manifestations of B-cell acute lymphoblastic leukemia/lymphoma.

A 2-year-old boy presented with left periorbital edema, proptosis, hyperglobus and esotropia. Imaging revealed an inferotemporal orbital mass with adjacent bony erosion. Histological evaluation of an orbital biopsy revealed B-cell acute lymphoblastic leukemia/lymphoma (B-ALL/BLL). The patient was subsequently treated with chemotherapy. Although orbital involvement in acute myelogenous leukemia has been well-described, orbital manifestations of B-ALL/BLL are uncommon, with only a limited number of previous reports in the literature.

Epithelial membrane protein 2 (EMP2) regulates hypoxia-induced angiogenesis in the adult retinal pigment epithelial cell lines.

Pathologic retinal neovascularization is a potentially blinding consequence seen in many common diseases including diabetic retinopathy, retinopathy of prematurity, and retinal vaso-occlusive diseases. This study investigates epithelial membrane protein 2 (EMP2) and its role as a possible modulator of angiogenesis in human retinal pigment epithelium (RPE) under hypoxic conditions. To study its effects, the RPE cell line ARPE-19 was genetically modified to either overexpress EMP2 or knock down its levels, and RNA sequencing and western blot analysis was performed to confirm the changes in expression at the RNA and protein level, respectively. Protein expression was evaluated under both normoxic conditions or hypoxic stress. Capillary tube formation assays with human umbilical vein endothelial cells (HUVEC) were used to evaluate functional responses. EMP2 expression was found to positively correlate with expression of pro-angiogenic factors HIF1α and VEGF at both mRNA and protein levels under hypoxic conditions. Mechanistically, EMP2 stabilized HIF1α expression through downregulation of von Hippel Lindau protein (pVHL). EMP2 mediated changes in ARPE-19 cells were also found to alter the secretion of a paracrine factor(s) in conditioned media that can regulate HUVEC migration and capillary tube formation in in vitro functional angiogenesis assays. This study identifies EMP2 as a potential mediator of angiogenesis in a human RPE cell line. EMP2 levels positively correlate with pro-angiogenic mediators HIF1α and VEGF, and mechanistically, EMP2 regulates HIF1α through downregulation of pVHL. This study supports further investigation of EMP2 as a promising novel target for therapeutic treatment of pathologic neovascularization in the retina.

Facial diplegia with paresthesia associated with anti-GD1a antibodies.

A 26-year-old previously healthy man presented with progressive facial diplegia and sensory deficits to pinprick in a stocking-glove distribution. Lumbar puncture revealed cytoalbuminologic dissociation, and a nerve conduction study of the right facial nerve demonstrated a proximal demyelinating process. He was started on intravenous immunoglobulin given concern for a Guillain-Barré syndrome variant, and his symptoms improved over several days. This case illustrates the clinical features of facial diplegia with paresthesias, a rare variant of Guillain-Barré syndrome. Unlike most reported cases of facial diplegia with paresthesias that have demonstrated positive anti-ganglioside M2 antibodies, this case is unique given the positivity of anti-ganglioside D1a IgG/IgM antibodies.

Google Searches for Thyroid Eye Disease After Regulatory Approval of Teprotumumab.

Importance: Given that direct-to-consumer advertising campaigns have the potential to both positively and negatively affect patient care, clinicians would benefit from being conscious of changes in public interest that result from such campaigns. Objective: To understand how direct-to-consumer advertising was associated with information-seeking behavior based on Google Trends. Design, Setting, and Participants: This descriptive cross-sectional study used Google Trends to examine relative search volumes for thyroid eye disease (TED) from January 1, 2004, to June 30, 2021, in the US. The data for this cross-sectional study were downloaded on October 17, 2021. This study included internet search engine queries originating within the US, as determined by Google Trends. Main Outcomes and Measures: Monthly changes in relative search volumes for the terms "thyroid eye disease," "Tepezza," and "teprotumumab." Results: From January 1, 2004, through June 30, 2019, searches for TED demonstrated a stable baseline level with a mean (SD) relative search volume of 1.78 (1.25). After US Food and Drug Administration approval of teprotumumab in January 2020, TED searches increased by 25%. After the manufacturer of teprotumumab ran its first national television commercial in December 2020, a 525% increase in TED searches was observed. After a second series of national television advertisements for teprotumumab in May 2021, TED searches increased by 640%. Conclusions and Relevance: Findings of this cross-sectional study suggest that direct-to-consumer advertising campaigns for teprotumumab may have been associated with an increase in internet search traffic for TED. Google Trends may serve as a useful tool for measuring the influence of pharmaceutical advertising campaigns on information-seeking behavior in the public. Additional studies are warranted to determine how these changes in public interest correlate with clinical measures, such as referral patterns.

The Reliability of 3-T Magnetic Resonance Imaging to Identify Arthroscopic Features of Meniscal Tears and Its Utility to Predict Meniscal Tear Reparability.

BACKGROUND: The ability to predict meniscus tear reparability based on preoperative magnetic resonance imaging (MRI) is desirable for postoperative planning; however, the accuracy of predictive methods varies widely within the orthopaedic and radiology literature. PURPOSE/HYPOTHESIS: The purpose was to determine if the higher resolution offered by 3-T MRI improves the accuracy of predicting reparability compared with previous investigations using 1.5-T MRI. Our hypothesis was that a higher field strength of 3-T MRI would result in improved reliability assessments and predictions of meniscus tear reparability compared with previous studies utilizing a 1.5-T MRI platform. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2. METHODS: A total of 44 patients who underwent meniscus repair were matched by age, sex, and body mass index to 43 patients who underwent partial meniscectomy. Overall, 2 orthopaedic surgeons and 2 musculoskeletal radiologists independently and blindly reviewed the preoperative MRI scans for all 87 patients. For each meniscus tear, reviewers evaluated the following criteria: tear pattern, tear length, tear distance from the meniscocapsular junction, tear thickness, and integrity of any inner meniscal fragment. The resultant data were then applied to 5 different approaches for predicting meniscal reparability. RESULTS: The accuracy for all examined prediction methods was poor, ranging from 55% (3-point method) to 72% (classification tree method) among all reviewers. Interobserver reliability for examined criteria was also poor, with kappa values ranging from 0.07 (inner meniscal fragment status) to 0.40 (tear pattern). CONCLUSION: MRI continues to be a poor predictor of meniscus tear reparability as assessed by arthroscopic criteria, even when using higher resolution 3-T scanners. Interobserver reliability in this setting can be poor, even among experienced clinicians.

Arthroscopic Repair of Type II SLAP Lesions in Overhead Athletes.

For overhead athletes and, in particular, baseball pitchers, the rates of success and return to play for those who have undergone arthroscopic repair of type II SLAP lesions are poor, ranging from 7% to 62%. The reasons for the poor results and high failure rates in overhead athletes with type II SLAP repairs are multifactorial and are a combination of many factors. These factors include the failure to establish the diagnosis and treat these athletes preoperatively; the inability of the operating surgeon to differentiate normal anatomic variants from pathologic SLAP lesions at the time of surgery; the surgical technique, which may violate the rotator cuff; or the placement of suture anchors, which restricts external rotation and alters overhead throwing mechanics. The proper diagnosis of SLAP lesions can be difficult because SLAP tears rarely occur in isolation and are often associated with other shoulder pathology. A proper history detailing the onset of symptoms and whether there was an acute episode of trauma or a history of repetitive use is critical. It is important to remember that no single physical examination finding is pathognomonic for SLAP tears. When seen in isolation, SLAP tears may mimic impingement syndrome (52%) or even anterior instability (39%). Surgical treatment of type II SLAP lesions should not be undertaken lightly in overhead athletes. If a 3-month rehabilitation period followed by a return to sports over the following 3 months does not allow the athlete to return to his or her preinjury level, diagnostic arthroscopy with SLAP repair is a reasonable option and can yield excellent results using the proper techniques. The technique described in detail in this article and our video can be technically demanding, but with the key points outlined, it can be reproduced and provide excellent results for overhead athletes undergoing SLAP repair. By not violating the rotator cuff, using a mattress configuration and keeping the suture knot away from the articular surface, and by not going anterior to the biceps tendon for repair, external rotation and strength can be preserved, leading to an excellent result with a predictable return to play for overhead athletes.
