Risk Factors for Chalazion Diagnosis and Subsequent Surgical Excision.

PURPOSE: To identify factors associated with chalazion diagnosis and surgical excision. METHODS: Patients with an incident chalazion diagnosis from 2002 to 2019 were compared 1:5 with matched controls. Multivariable logistic regression was performed to identify variables associated with diagnosis and surgical excision. RESULTS: Chalazion patients (n = 134,959) and controls (678,160) were analyzed. Risk factors for diagnosis included female sex, non-white race, northeast location, conditions affecting periocular skin and tear film (blepharitis, meibomian gland dysfunction, rosacea, pterygium), non-ocular inflammatory conditions (gastritis, inflammatory bowel disease, sarcoidosis, seborrheic dermatitis, Graves' disease), and smoking (p < .001 for all comparisons). Thirteen percent of patients with chalazion underwent subsequent surgical excision. Diabetes and systemic sclerosis diagnoses decreased odds of diagnosis (p < .001). Male sex, rosacea diagnosis, Black and Hispanic race, antibiotic use, and doxycycline use increased odds of surgery (p < .001). CONCLUSION: Female sex, non-white race, conditions affecting periocular skin and the tear film, several non-ocular inflammatory conditions, and smoking were risk factors for chalazion diagnosis. Male sex, rosacea diagnosis, Black and Hispanic race, antibiotic use, and doxycycline use were risk factors for surgical intervention for chalazion. Our results prompt further study of these variables and their relationship to chalazion diagnosis to understand physiology and improve clinical outcomes. Furthermore, the results of this study suggest early recognition and treatment of concomitant rosacea may serve an important role in the management of chalazion and in the prevention of surgical intervention.

SGLT2 inhibitors and diabetic retinopathy progression.

PURPOSE: To evaluate whether sodium-glucose co-transporter 2 (SGLT2) inhibitors affect progression of non-proliferative diabetic retinopathy (NPDR) compared to standard of care. METHODS: A retrospective cohort study compared subjects enrolled in a commercial and Medicare Advantage medical claims database who filled a prescription for a SGLT2 inhibitor between 2013 and 2020 to unexposed controls, matched up to a 1:3 ratio. Patients were excluded if they were enrolled for less than 2 years in the plan, had no prior ophthalmologic exam, had no diagnosis of NPDR, had a diagnosis of diabetic macular edema (DME) or proliferative diabetic retinopathy (PDR), had received treatment for vision-threatening diabetic retinopathy (VTDR), or were younger than 18 years. To balance covariates of interest between the cohorts, an inverse probability treatment weighting (IPTW) propensity score for SGLT2 inhibitor exposure was used. Multivariate Cox proportional hazard regression modeling was employed to assess the hazard ratio (HR) for VTDR, PDR, or DME relative to SGLT2 exposure. RESULTS: A total of 6065 patients who initiated an SGLT2 inhibitor were matched to 12,890 controls. There were 734 (12%), 657 (10.8%), and 72 (1.18%) cases of VTDR, DME, and PDR, respectively, in the SGLT2 inhibitor cohort. Conversely, there were 1479 (11.4%), 1331 (10.3%), and 128 (0.99%) cases of VTDR, DME, and PDR, respectively, among controls. After IPTW, Cox regression analysis showed no difference in hazard for VTDR, PDR, or DME in the SGLT2 inhibitor-exposed cohort relative to the unexposed group [HR = 1.04, 95% CI 0.94 to 1.15 for VTDR; HR = 1.03, 95% CI 0.93 to 1.14 for DME; HR = 1.22, 95% CI 0.89 to 1.67 for PDR]. CONCLUSION: Exposure to SGLT2 inhibitor therapy was not associated with progression of NPDR compared to patients receiving other diabetic therapies.

Long-Term Burden of Pain and Reduced Visual Acuity after Gunshot Wounds to the Orbit.

PURPOSE: To characterize the clinical presentation, surgical management, long-term complications and outcomes of Gunshot Wounds(GSW) to the orbit. METHODS: An extended case series with retrospective chart-review was conducted on all cases (1985-2020) of traumatic ocular injuries secondary to GSWs at an academic institution with a level 1 trauma center. Predictors included demographic information, clinical and radiologic examination findings, and surgical intervention at time of presentation. Outcomes included long-term lid malposition, visual acuity, pain, and secondary surgery. Descriptive statistics and tests of association were performed, including Fishers exact tests for categorical data, Kruskal-Wallis rank sum tests, analysis of variance, and, in the case of repeated measures, generalized estimating equations. RESULTS: 88 patients with GSW involving the orbit were included with average age of 32.6 years (sd = 15.7). Patients were 85.2% male, 75% African-American, 25.0% Caucasian, and 5.7% Hispanic. Median follow up was 43.3 months (4.6, 136.4). The injuries at presentation were 53.4% intracranial, 21.6% open globe, 80.7% orbital fracture, 89.8% lid laceration. Visual acuity did not significantly improve over time. Long-term complications included abnormal lid or globe position in 26.1% of patients, reduced visual acuity in 55.2%, and persistent pain in 50.6%. CONCLUSION: To our knowledge, this represents the first and largest clinical epidemiologic study with insight into the clinical presentation, surgical intervention, and long-term outcomes of GSW to the orbit. The results demonstrate a long-term burden of persistent pain and reduced visual acuity in patients who suffer from GSW to the globe and orbit. This study may guide patient management and communications.

Mohs Micrographic Surgery for Facial Merkel Cell Carcinoma.

BACKGROUND: Merkel cell carcinoma (MCC) is a rare malignant cutaneous tumor with frequent metastases. They often appear in the face where cosmetic and functional outcome is critical. Mohs micrographic surgery (MMS) is a controlled intervention that optimizes negative margins without sacrificing tissue. OBJECTIVE: A comprehensive assessment of outcomes of MMS-treated facial MCC will help guide clinicians in surgical and medical management. METHODS & MATERIALS: Retrospective review identified facial MCC cases treated with MMS at a single institution from January 2005 to August 2020. Tumor characteristics and outcomes were recorded and descriptive and predictive analyses were performed. RESULTS: 34 cases were reviewed with a mean followup of 34.4 months. The most common sites were the forehead, cheek-jaw region, and nasal ala. 2 (5.9%) patients had local recurrence by a mean of 4.3 months. No documented variables were significantly associated with local recurrence. 8 (23.5%) patients had progression to metastasis by a mean of 9.4 months. Younger age at biopsy and surgery, male sex, and intraoperative detection of in-transit disease were significantly associated with progression to metastasis. CONCLUSIONS: In summary, the tissue-sparing approach of MMS may be beneficial for MCC in cosmetically and functionally sensitive facial locations as it preserves tissue without compromising outcomes.

Sebaceous Carcinoma of the Face Treated With Mohs Micrographic Surgery.

BACKGROUND: Mohs micrographic surgery (MMS) for sebaceous carcinoma (SC) may reduce local recurrence rates, but published case series have small cohorts and limited follow-up. Mohs micrographic surgery is particularly suitable for sensitive functional and cosmetic locations, such as the face, because it facilitates tissue conservation using complete peripheral and deep margin assessment before reconstruction. Coordinated care between Mohs and oculoplastic surgeons has not been described. OBJECTIVE: To assess rates of local recurrence and metastasis after MMS of facial SC and to describe coordinated care between Mohs and oculoplastic surgeons. MATERIALS AND METHODS: Retrospective review identified facial SC cases treated with MMS at a single institution from January 2005 to August 2020. Tumor characteristics and outcomes were recorded. Descriptive and predictive analyses were performed. RESULTS: Forty-nine cases were reviewed with a mean follow-up of 51 months. The most common sites were periorbital, infraorbital cheek, and nasal ala. No patients experienced regional recurrence after MMS. One patient with Muir-Torre syndrome developed metastatic recurrence (at 82.9 months). All patients underwent 2-stage reconstruction with dermatology-performed MMS and oculoplastic reconstruction. CONCLUSION: Collaboration between Mohs and oculoplastic surgeons with a tissue-sparing approach of MMS can reduce recurrence and optimize cosmesis and function for central facial SC.

Statin use and the risk of progression to vision threatening diabetic retinopathy.

PURPOSE: This study aims to assess the effect of statins on progression from nonproliferative diabetic retinopathy (NPDR) to vision-threatening diabetic retinopathy (VTDR), proliferative diabetic retinopathy (PDR) or diabetic macular edema (DME). METHODS: Two cohort studies using a U.S. medical claims database from 2002 to 2019 including NPDR patients 18 years or older. A risk factor analysis performed a time-updating cox regression model assessing statin usage. A second new-user active comparator design analysis replicating a previously published study. Main outcomes included a new diagnosis of VTDR (composite of either PDR or DME) or DME and PDR individually for the risk factor study and included additional outcomes of new DR, NPDR, vitreous hemorrhage (VH) and tractional retinal detachment (TRD) for the new user study. RESULTS: Risk factor analysis included 66 617 statin users with NPDR at baseline and 83 365 nonstatin users. Of these, 27 325 (18.2%) progressed to VTDR, 4086 (2.71%) progressed to PDR, and 22 750 (15.1%) progressed to DME. After multivariable analysis, no protective effect of statin use was found for progression to VTDR, PDR, or DME (HR = 1.01-3, p >0.33 for all comparisons). Replicated new user design analysis also showed no protective effect for statins on risk of development of DR (HR = 1.03, 95% CI: 0.99-1.07, p = 0.13), PDR (HR = 0.89, 95% CI: 0.79-1.02, p = 0.09), DME (HR = 0.94, 95% CI: 0.86-1.03, p = 0.21), VH (HR = 1.00, 95% CI: 0.86-1.16, p = 0.99), and TRD (HR = 1.11, 95% CI: 0.89-1.38, p = 0.36). CONCLUSION: Statin use was found not to be protective for progression of DR regardless of study methodology. These results suggest that the specifics of the population studied rather than differing study methodology are important in assessing the effect of statins on DR progression.

Comparison of Visual Acuity Results Between ATS-HOTV and E-ETDRS Testing Methods in Children With Optic Pathway Gliomas.

Purpose: To determine if visual acuity (VA) outcomes are comparable using the amblyopia treatment study HOTV protocol (ATS-HOTV) and electronic Early Treatment of Diabetic Retinopathy Study (E-ETDRS) protocol in children with optic pathway gliomas (OPGs). Methods: Children enrolled in a prospective study of OPGs were eligible if they completed both the ATS-HOTV and E-ETDRS during the same visit. The contribution of age, testing order, having neurofibromatosis type 1, visual field loss, and circumpapillary retinal nerve fiber layer thickness to VA difference were assessed using generalized estimating equations to account for the intereye correlation. Results: Forty-eight children (median age, 10.3 years; range, 5.2-17.1 years; 49% female) met inclusion criteria and contributed 93 study eyes at their initial visit. Eleven patients (22 eyes) had more than one study visit, permitting longitudinal evaluation. ATS-HOTV measures of VA were higher than E-ETDRS at the initial (0.13 ± 0.36 vs. 0.23 ± 0.39 logarithm of the minimum angle of resolution [logMAR], P < 0.001) and all visits (0.13 ± 0.34 vs. 0.21 ± 0.36 logMAR, P < 0.001). VA remained significantly higher with ATS-HOTV regardless of test order, but the mean difference between tests was most profound when tested with ATS-HOTV first compared to E-ETDRS first (P < 0.001). Conclusions: VA results differ significantly between the ATS-HOTV and E-ETDRS testing methods in children with OPGs. Given the wide range of ages and testing ability of children, one VA testing method should be used throughout longitudinal OPG clinical trials. Translational Relevance: It is imperative that age-appropriate VA testing methods are standardized across all pediatric OPG clinical trials.

Tobacco counseling in the setting of thyroid eye disease / Aconselhamento sobre o uso de tabaco no contexto de doenças oculares associadas à tireoide

ABSTRACT Purpose: To collect data on the rate and efficacy of tobacco counseling sessions delivered by ophthalmologists under the setting of patients with thyroid eye disease. Methods: We analyzed the electronic medical records of a digital cohort of patients who visited ophthalmologists at the University of Pennsylvania Health System from 2012 to 2017 with reference to the International Classification of Disease (ICD) codes for Graves' disease, thyrotoxic exophthalmos, and/or thyroid eye disease. Tobacco histories were recorded at the first and last ophthalmology office visits or the most temporally proximal encounter in packs/day (ppd), and each ophthalmology visit note was analyzed to validate the occurrence of tobacco counseling. Results: A total of 435 patients met our study inclusion criteria, of which 72 (16.6%) were active smokers at the time of their first visit. Only 57 (79.2%) of these active smokers had recorded smoking burdens, 34 (59.6%) of which received at least one form of recorded tobacco counseling session. Nine (26.5%) of the subjects who received tobacco counseling and 1 (4.3%) of those who did not have a recorded counseling, quit smoking (risk difference of 22.1%; 95% CI, [1.7%, 39.1%]; p=0.04). In addition, 17 (50.0%) of the subjects who received counseling and 7 (30.4%) of those who did not have a recorded counseling, reduced their ppd consumption (risk difference of 19.6%; 95% CI [-6.3%, 41.3%]; p=0.18). Overall, 14 (25.5%) out of the 55 ophthalmologists who were active smokers had recorded evidence of tobacco counseling. Conclusions: Our cumulative results provide the consequence of both missed opportunities for tobacco counseling as well as its efficacy in the setting of thyroid eye disease.

RESUMO Objetivo: Fornecer informações sobre a ocorrência e a eficácia do aconselhamento sobre o uso de tabaco por oftalmologistas a pacientes com doenças oculares associadas à tireoide. Métodos: Analisamos os prontuários médicos eletrônicos de uma coorte digital de pacientes atendidos por oftalmologistas no Sistema de Saúde da Universidade da Pensilvânia entre o início de 2012 e o final de 2017 com os códigos da Classificação Internacional de Doenças (CID) para a doença de Graves, exoftalmia tireotóxica ou doença ocular associada à tireoide. Os históricos de uso de tabaco foram registrados na primeira e na última visita ao consultório de Oftalmologia, ou na visita mais próxima no tempo. A quantidade de maços/dia (mpd) e todas as anotações feitas nas visitas ao consultório de Oftalmologia foram analisadas para aconselhamento sobre o uso de tabaco. Resultados: Um total de 435 indivíduos preencheram os critérios de inclusão, dos quais 72 (16,6%) estavam fumando ativamente no momento do primeiro encontro. Apenas 57 (79,2%) desses indivíduos que fumam ativamente registraram queixas relacionadas ao tabagismo, sendo que 34 (59,6%) deles receberam alguma forma de aconselhamento sobre o uso de tabaco. Ao todo, 9 (26,5%) indivíduos dentre os que receberam aconselhamento sobre tabaco e 1 (4,3%) que não teve aconselhamento registrado pararam de fumar (diferença de risco de 22,1%; IC 95%, [1,7%, 39,1%]; p=0,04). Dentre aqueles que receberam aconselhamento, 17 (50,0%) reduziram seus mpd, além de 7 (30,4%) daqueles que não tiveram aconselhamento (diferença de risco de 19,6%; IC 95% [-6,3%, 41,3%]; p=0,18). No geral, 14 (25,5%) dos 55 oftalmologistas que tiveram um paciente fumante ativo registraram evidências de aconselhamento sobre o uso de tabaco. Conclusões: Os resultados deste estudo revelam tanto as oportunidades perdidas de aconselhamento sobre o uso do tabaco quanto a eficácia do aconselhamento no contexto de doenças oculares associadas à tireoide.

Elevated Intracranial Pressure in Patients with Craniosynostosis by Optical Coherence Tomography.

BACKGROUND: Craniosynostosis may lead to elevated intracranial pressure, which may be implicated with impaired neurocognitive development. However, accurately measuring intracranial pressure is challenging, and patterns in craniosynostosis patients are poorly characterized. Spectral-domain optical coherence tomography may enable noninvasive assessment of intracranial pressure in pediatric patients with craniosynostosis. METHODS: Pediatric patients with craniosynostosis undergoing surgical intervention between 2014 and 2019 prospectively underwent optical coherence tomographic evaluation. Intracranial pressure was directly measured intraoperatively in a subset of cases. Optical coherence tomographic parameters were compared to directly measured intracranial pressure and used for pattern assessment. RESULTS: Optical coherence tomography was performed in 158 subjects, among which 42 underwent direct intracranial pressure measurement during an initial cranial procedure. Maximal retinal nerve fiber layer thickness, maximal retinal thickness, and maximal anterior projection optical coherence tomographic parameters were positively correlated with intracranial pressure (p ≤ 0.001), with all parameters showing significantly higher values in patients with intracranial pressure thresholds of 15 mmHg (p < 0.001) and 20 mmHg (p ≤ 0.007). Patients with maximal retinal nerve fiber layer thickness and maximal anterior projection exceeding set thresholds in optical coherence tomography of either eye demonstrated 77.3 percent sensitivity and 95.0 percent specificity for detecting intracranial pressure above 15 mmHg, and 90.0 percent sensitivity and 81.3 percent specificity for detecting intracranial pressure above 20 mmHg. Patients with associated syndromes or multiple suture involvement and patients aged 9 months or older were significantly more likely to have elevated intracranial pressure above 15 mmHg (p ≤ 0.030) and above 20 mmHg (p ≤ 0.035). CONCLUSIONS: Spectral-domain optical coherence tomography can noninvasively detect elevated intracranial pressure in patients with craniosynostosis with reliable sensitivity and specificity. This technology may help guide decisions about the appropriate type and timing of surgical treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, I.

Risk of non-infectious uveitis or myasthenia gravis in patients on checkpoint inhibitors in a large healthcare claims database.

AIM: To determine if checkpoint inhibitors (CPIs) confer an increased risk of non-infectious uveitis or myasthenia gravis (MG) compared to patients on non-checkpoint inhibitor (N-CPI) chemotherapy. METHODS: A retrospective cohort study was performed comparing patients in a large commercial and Medicare advantage database exposed to CPI compared to N-CPI. All patients who initiated a CPI (ipilimumab, pembrolizumab, nivolumab, atezolizumab, avelumab, cemiplimab and durvalumab) were eligible. Date of earliest CPI in the exposure group and N-CPI chemotherapy in the comparator group was considered the index date. Exclusion occurred in both cohorts for any history of uveitis or MG diagnosis and having <1 year in the insurance plan prior to the index date, and <6 months in plan following the index date. Every exposed patient was matched up to 1:10 based on demographics and index year to patients on N-CPI chemotherapy. Multivariate Cox proportional hazards regression modelling was performed. RESULTS: For evaluation of incidence of non-infectious uveitis, 26 (0.3%) of 8678 patients on CPI and 123 (0.2%) of 76 153 N-CPI comparators were found to have non-infectious uveitis. After multivariate analysis, CPIs showed an increased hazard for uveitis compared to N-CPI (HR=2.09; 95% CI 1.36 to 3.22, p=0.001). For the MG analysis, 11 (0.1%) of 9210 patients developed MG in the CPI group and 36 (0.04%) of 80 620 comparators. The CPI cohort had a higher hazard of developing MG (HR=2.60; 95% CI 1.34 to 5.07, p=0.005) compared to controls in multivariate analysis. CONCLUSIONS: Exposure to CPI confers a higher risk for non-infectious uveitis and MG compared to N-CPI chemotherapy.

Clinicopathologic Characteristics and Prognostic Factors Impacting Survival in Melanoma of the Eyelid.

PURPOSE: To examine prognostic factors for survival in patients with melanoma of the eyelid. DESIGN: Retrospective cohort study. METHODS: This population-based study reviewed patients with primary melanoma of the eyelid diagnosed in the Surveillance, Epidemiology and End Results database between 1975 and 2016. The primary outcomes included survival rates estimated by Kaplan-Meier analysis and mortality hazard ratios (HRs) for overall survival and disease-specific survival (DSS). RESULTS: The cohort consisted of 2257 patients with cutaneous melanoma of the eyelid, representing 1380 cases of melanoma in situ and 877 cases of invasive melanoma. For melanoma in situ and invasive melanoma respectively, at 5 years, the overall survival rates were 88.6% and 77.1%, while DSS rates were 99.4% and 91.0%. Cox regression analysis for eyelid melanoma indicated that for invasive melanoma, age at diagnosis ≥75 years (HR 2.17 [95% confidence interval {CI} 1.02-4.60]; P = .04), T4 staging (HR 8.45 [95% CI 2.96-25.31]; P < .001), lymph node involvement (HR 3.61 [95% CI 1.12-11.60]; P = .03), and nodular melanoma (HR 3.31 [95% CI 1.50-7.32]; P = .003) histologic subtype were associated with decreased rates of survival. Sex and tumor ulceration did not impact survival. CONCLUSIONS: This study is the largest analysis to date that focuses on DSS for cutaneous melanoma of the eyelid. The most significant predictors for invasive melanoma survival are age ≥75 years at diagnosis, T4 staging, lymph node involvement, and the nodular melanoma histologic subtype. Patients with these attributes are at higher risk and should be counseled regarding prognosis.

In addition, 17 (50.0%) of the subjects who received counseling and 7 (30.4%) of those who did not have a recorded counseling, reduced their ppd consumption (risk difference of 19.6%; 95% CI [-6.3%, 41.3%]; p=0.18). Overall, 14 (25.5%) out of the 55 ophthalmologists who were active smokers had recorded evidence of tobacco counseling. CONCLUSIONS: Our cumulative results provide the consequence of both missed opportunities for tobacco counseling as well as its efficacy in the setting of thyroid eye disease.

Systemic Factors Associated with a Thinner Choroid in Preterm Infants.

Purpose: To identify systemic health factors associated with a thinner choroid, which has been hypothesized as a cause of poor visual outcomes in low-birth weight infants. Design: The prospective, observational Study of Eye Imaging in Preterm Infants (BabySTEPS) enrolled infants recommended for retinopathy of prematurity screening based on the American Association of Pediatrics guidelines. Participants: Infants who underwent imaging with investigational handheld OCT at 36 ± 1 weeks' postmenstrual age (PMA) as part of BabySTEPS. Methods: Average choroidal thickness was measured across the central subfoveal 1 mm. We concurrently collected maternal and infant clinical health data. Univariate and multivariate linear regression analyses were performed to evaluate factors associated with choroidal thickness. The left and right eyes showed similar thicknesses, so their average was used for analysis. Main Outcomes Measures: Association between infant health factors and subfoveal choroidal thickness. Results: Subfoveal choroidal thickness was measurable in 82 of 85 infants and 94% of eyes. Mean choroidal thickness was 231 ± 78 µm. In the univariate analysis, a thinner choroid was associated with decreased growth velocity (P < 0.001), lower birth weight (P < 0.001), smaller head circumference (P < 0.001), younger gestational age (P = 0.01), the presence of patent ductus arteriosus (P = 0.05), sepsis or necrotizing enterocolitis (P = 0.03), bronchopulmonary dysplasia (P = 0.03), pulmonary interstitial emphysema (P = 0.002), more days on oxygen support (P < 0.001), and being on oxygen support at 36 weeks (P < 0.001) and at the time of imaging (P < 0.001). In the multivariate analysis, growth velocity (P = 0.002) and oxygen support at the time of OCT imaging (P = 0.004) remained associated with a thinner choroid. Conclusions: A thinner choroid is associated independently with growth velocity and receiving oxygen support at 36 ± 1 weeks PMA. This suggests that choroidal development in preterm infants may be related to growth rate in the first weeks of life and the prolonged use of supplemental oxygen. Longitudinal studies are needed to assess differences in choroidal thickness before 36 weeks PMA and to assess their impact on visual outcomes.

Primary orbital melanoma: A report of a case and comprehensive review of the literature.

Purpose: To review the clinical features and treatment-associated outcomes of primary orbital melanoma among cases reported in the literature and to present a case treated with orbital exenteration and post-operative radiotherapy.Methods: Case reports and case series on primary orbital melanoma published in the literature between 1980 and 2020 were reviewed. Data collected included patient demographics, presenting ocular symptoms, diagnostic imaging, histology, management, and outcomes.Results: Eighty-eight cases of primary orbital melanoma were reviewed. The average age at presentation was 45 years and 58% of patients were male. The most common presenting symptoms and signs were proptosis (73%), decreased visual acuity (32%), pain (14%), diplopia (15%), and palpable mass (9%). Imaging frequently showed a well-circumscribed enhancing lesion. Diagnosis was made by histology in all cases, and orbital blue nevus was identified in 42%. In the majority of cases, treatment consisted of orbital exenteration (54%) or excision (38%). Adjuvant radiotherapy was given in 47% of cases. For the 72 patients with reported outcomes, 36% had metastases, 15% had local recurrence, and 32% died of metastatic disease. Patients who received surgery and radiotherapy had improved survival compared to those who received surgery alone (p = .01). There was no difference in survival between those who underwent orbital exenteration or excision (p = .16).Conclusions: Primary orbital melanoma is a rare malignancy and should be considered in patients with a history of unilateral proptosis and a well-defined orbital mass on imaging. Surgery remains the mainstay of treatment. Adjuvant radiotherapy may improve patient survival.

Childhood adversity impact on gut microbiota and inflammatory response to stress during pregnancy.

BACKGROUND: Adverse childhood experiences (ACEs), such as abuse or chronic stress, program an exaggerated adult inflammatory response to stress. Emerging rodent research suggests that the gut microbiome may be a key mediator in the association between early life stress and dysregulated glucocorticoid-immune response. However, ACE impact on inflammatory response to stress, or on the gut microbiome, have not been studied in human pregnancy, when inflammation increases risk of poor outcomes. The aim of this study was to assess the relationships among ACE, the gut microbiome, and cytokine response to stress in pregnant women. METHODS: Physically and psychiatrically healthy adult pregnant women completed the Adverse Childhood Experiences Questionnaire (ACE-Q) and gave a single stool sample between 20 and 26 weeks gestation. Stool DNA was isolated and 16S sequencing was performed. Three 24-hour food recalls were administered to assess dietary nutrient intake. A subset of women completed the Trier Social Stress Test (TSST) at 22-34 weeks gestation; plasma interleukin-6 (IL-6), interleukin-1ß (IL-1ß), high sensitivity C-reactive protein (hsCRP), tumor necrosis factor α (TNF-α), and cortisol were measured at four timepoints pre and post stressor, and area under the curve (AUC) was calculated. RESULTS: Forty-eight women completed the ACE-Q and provided stool; 19 women completed the TSST. Women reporting 2 or more ACEs (high ACE) had greater differential abundance of gut Prevotella than low ACE participants (q = 5.7 × 10^-13). Abundance of several gut taxa were significantly associated with cortisol, IL-6, TNF-α and CRP AUCs regardless of ACE status. IL-6 response to stress was buffered among high ACE women with high intake of docosahexaenoic acid (DHA) (p = 0.03) and eicosapentaenoic acid (EPA) (p = 0.05). DISCUSSION: Our findings suggest that multiple childhood adversities are associated with changes in gut microbiota composition during pregnancy, and such changes may contribute to altered inflammatory and glucocorticoid response to stress. While preliminary, this is the first study to demonstrate an association between gut microbiota and acute glucocorticoid-immune response to stress in a clinical sample. Finally, exploratory analyses suggested that high ACE women with high dietary intake of ω-3 polyunsaturated fatty acids (PUFAs) had a dampened inflammatory response to acute stress, suggesting potentially protective effects of ω-3s in this high-risk population. Given the adverse effects of inflammation on pregnancy and the developing fetus, mechanisms by which childhood adversity influence the gut-brain axis and potential protective factors such as diet should be further explored.
