Outcomes and Complications of Limbal Stem Cell Allograft Transplantation: A Report by the American Academy of Ophthalmology. Ophthalmology 2024:S0161-6420(24)00157-X. [PMID: 38678469 DOI: 10.1016/j.ophtha.2024.02.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 02/13/2024] [Indexed: 05/01/2024] Open
Abstract
PURPOSE To review the published literature on the safety and outcomes of keratolimbal allograft (KLAL) transplantation and living-related conjunctival limbal allograft (lr-CLAL) transplantation for bilateral severe/total limbal stem cell deficiency (LSCD). METHODS Literature searches were last conducted in the PubMed database in February 2023 and were limited to the English language. They yielded 523 citations; 76 were reviewed in full text, and 21 met the inclusion criteria. Two studies were rated level II, and the remaining 19 studies were rated level III. There were no level I studies. RESULTS After KLAL surgery, best-corrected visual acuity (BCVA) improved in 42% to 92% of eyes at final follow-up (range, 12-95 months). The BCVA was unchanged in 17% to 39% of eyes and decreased in 8% to 29% of eyes. Two of 14 studies that evaluated the results of KLAL reported a notable decline in visual acuity over time postoperatively. Survival of KLAL was variable, ranging from 21% to 90% at last follow-up (range, 12-95 months) and decreased over time. For patients undergoing lr-CLAL surgery, BCVA improved in 31% to 100% of eyes at final follow-up (range, 16-49 months). Of the 9 studies evaluating lr-CLAL, 4 reported BCVA unchanged in 30% to 39% of patients, and 3 reported a decline in BCVA in 8% to 10% of patients. The survival rate of lr-CLAL ranged from 50% to 100% at final follow-up (range, 16-49 months). The most common complications were postoperative elevation of intraocular pressure, persistent epithelial defects, and acute allograft immune rejections. CONCLUSIONS Given limited options for patients with bilateral LSCD, both KLAL and lr-CLAL are viable choices that may provide improvement of vision and ocular surface findings. The studies trend toward a lower rejection rate and graft failure with lr-CLAL. However, the level and duration of immunosuppression vary widely between the studies and may impact allograft rejections and long-term graft survival. Complications related to immunosuppression are minimal. Repeat surgery may be needed to maintain a viable ocular surface. Reasonable long-term success can be achieved with both KLAL and lr-CLAL with appropriate systemic immunosuppression.

Treatment of Noninfectious Uveitic Macular Edema with Periocular and Intraocular Corticosteroid Therapies: A Report by the American Academy of Ophthalmology. Ophthalmology 2024:S0161-6420(24)00158-1. [PMID: 38647511 DOI: 10.1016/j.ophtha.2024.02.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Accepted: 02/09/2024] [Indexed: 04/25/2024] Open
Abstract
PURPOSE To review the evidence on the effectiveness and complications of periocular and intraocular corticosteroid therapies for noninfectious uveitic macular edema. METHODS A literature search of the PubMed database was conducted last in December 2021 and a post-assessment search was conducted in March 2023. The searches were limited to articles published in English and no date restrictions were imposed. The combined searches yielded 739 citations; 53 articles were selected for inclusion because the studies (1) evaluated periocular corticosteroid injection, intraocular corticosteroid injection or implant, suprachoroidal corticosteroid injection, or a combination thereof for uveitic macular edema; (2) had outcomes that included visual acuity (VA) or macular edema assessed clinically or imaged by OCT or fluorescein angiography; and (3) included more than 20 patients. RESULTS This assessment reviewed 23 articles that provided level I or level II evidence from 18 studies on the use of periocular, suprachoroidal, and intravitreal triamcinolone acetonide injections and intravitreal dexamethasone and fluocinolone acetonide implants or inserts in noninfectious uveitic macular edema. These reports consistently demonstrated that all investigated periocular and intraocular corticosteroid therapies improved VA, macular structure, or both. One comparative study showed that intravitreal triamcinolone acetonide injection and the dexamethasone intravitreal implant had effectiveness superior to that of periocular triamcinolone acetonide injection for these outcomes. As a group, the studies highlighted the potential for these therapies to elevate intraocular pressure and to accelerate cataract formation. CONCLUSIONS The published literature provides high-quality evidence that periocular and intraocular corticosteroid therapies are effective and safe for the treatment of noninfectious uveitic macular edema. However, information on the relative effectiveness and complication rates across the different therapies is limited.

Effectiveness of Conventional Digital Fundus Photography-Based Teleretinal Screening for Diabetic Retinopathy and Diabetic Macular Edema: A Report by the American Academy of Ophthalmology. Ophthalmology 2024:S0161-6420(24)00156-8. [PMID: 38613533 DOI: 10.1016/j.ophtha.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 02/06/2024] [Accepted: 02/09/2024] [Indexed: 04/15/2024] Open
Abstract
PURPOSE This American Academy of Ophthalmology Ophthalmic Technology Assessment aims to assess the effectiveness of conventional teleretinal screening (TS) in detecting diabetic retinopathy (DR) and diabetic macular edema (DME). METHODS A literature search of the PubMed database was conducted most recently in July 2023 to identify data published between 2006 and 2023 on any of the following elements related to TS effectiveness: (1) the accuracy of TS in detecting DR or DME compared with traditional ophthalmic screening with dilated fundus examination or 7-standard field Early Treatment Diabetic Retinopathy Study photography, (2) the impact of TS on DR screening compliance rates or other patient behaviors, and (3) cost-effectiveness and patient satisfaction of TS compared with traditional DR screening. Identified studies then were rated based on the Oxford Centre for Evidence-Based Medicine grading system. RESULTS Eight level I studies, 14 level II studies, and 2 level III studies were identified in total. Although cross-study comparison is challenging because of differences in reference standards and grading methods, TS demonstrated acceptable sensitivity and good specificity in detecting DR; moderate to good agreement between TS and reference-standard DR grading was observed. Performance of TS was not as robust in detecting DME, although the number of studies evaluating DME specifically was limited. Two level I studies, 5 level II studies, and 1 level III study supported that TS had a positive impact on overall DR screening compliance, even increasing it by more than 2-fold in one study. Studies assessing cost-effectiveness and patient satisfaction were not graded formally, but they generally showed that TS was cost-effective and preferred by patients over traditional surveillance. CONCLUSIONS Conventional TS is an effective approach to DR screening not only for its accuracy in detecting referable-level disease, but also for improving screening compliance in a cost-effective manner that may be preferred by patients. Further research is needed to elucidate the ideal approach of TS that may involve integration of artificial intelligence or other imaging technologies in the future.

Efficacy and safety of shunt surgery in patients with idiopathic normal-pressure hydrocephalus: can we predict shunt response by preoperative magnetic resonance imaging (MRI)? Clin Radiol 2024:S0009-9260(24)00142-9. [PMID: 38622045 DOI: 10.1016/j.crad.2024.03.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 02/28/2024] [Accepted: 03/05/2024] [Indexed: 04/17/2024]
Abstract
AIM The aim of this study was to identify preoperative magnetic resonance imaging (MRI) findings that can predict the shunt responsiveness in idiopathic normal-pressure hydrocephalus (iNPH) patients and to investigate postoperative outcome and complications. MATERIALS AND METHODS A total of 192 patients with iNPH who underwent shunt at our hospital between 2000 and 2021 were included to investigate complications. Of these, after exclusion, 127 (1-month postoperative follow-up) and 77 (1-year postoperative follow-up) patients were evaluated. The preoperative MRI features (the presence of tightness of the high-convexity subarachnoid space, Sylvian fissure enlargement, Evans' index, and callosal angle) of the shunt-response and nonresponse groups were compared, and a systematic review was conducted to evaluate whether preoperative MRI findings could predict shunt response. RESULTS Postoperative complications within one month after surgery were observed in 6.8% (13/192), and the most common complication was hemorrhage. Changes in corpus callosum were observed in 4.2% (8/192). The shunt-response rates were 83.5% (106/127) in the 1-month follow-up group and 70.1% (54/77) in 1-year follow-up group. In the logistic regression analysis, only Evans' index measuring >0.4 had a significant negative relationship with shunt response at 1-month follow-up; however, no significant relationship was observed at 1-year follow-up. According to our systematic review, it is still controversial whether preoperative MRI findings could predict shunt response. CONCLUSION Evans' index measure of >0.4 had a significant relationship with the shunt response in the 1-month follow-up group. In systematic reviews, there is ongoing debate about whether preoperative MRI findings can accurately predict responses to shunt surgery. Postoperative corpus callosal change was observed in 4.2% of iNPH patients.

Metabolomic profiles of ovariectomized mice and their associations with body composition and frailty-related parameters in postmenopausal women. J Endocrinol Invest 2024:10.1007/s40618-024-02338-x. [PMID: 38493245 DOI: 10.1007/s40618-024-02338-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 02/12/2024] [Indexed: 03/18/2024]
Abstract
BACKGROUND Menopause, a dramatical estrogen-deficient condition, is considered the most significant milestone in women's health. PURPOSE To investigate the metabolite changes attributed to estrogen deficiency using random forest (RF)-based machine learning (ML) modeling strategy in ovariectomized (OVX) mice as well as determine the clinical relevance of selected metabolites in older women. METHODS AND RESULTS Untargeted and targeted metabolomic analyses revealed that metabolites related to TCA cycle, sphingolipids, phospholipids, fatty acids, and amino acids, were significantly changed in the plasma and/or muscle of OVX mice. Subsequent ML classifiers based on RF algorithm selected alpha-ketoglutarate (AKG), arginine, carnosine, ceramide C24, phosphatidylcholine (PC) aa C36:6, and PC ae C42:3 in plasma as well as PC aa 34:1, PC aa C34:3, PC aa C36:5, PC aa C32:1, PC aa C36:2, and sphingosine in muscle as top featured metabolites that differentiate the OVX mice from the sham-operated group. When circulating levels of AKG, arginine, and carnosine, which showed the most significant changes in OVX mice blood, were measured in postmenopausal women, higher plasma AKG levels were associated with lower bone mass, weak grip strength, poor physical performance, and increased frailty risk. CONCLUSIONS Metabolomics- and ML-based methods identified the key metabolites of blood and muscle that were significantly changed after ovariectomy in mice, and the clinical implication of several metabolites was investigated by looking at their correlation with body composition and frailty-related parameters in postmenopausal women. These findings provide crucial context for understanding the diverse physiological alterations caused by estrogen deficiency in women.

Toric Monofocal Intraocular Lenses for the Correction of Astigmatism during Cataract Surgery: A Report by the American Academy of Ophthalmology. Ophthalmology 2024; 131:383-392. [PMID: 38149945 DOI: 10.1016/j.ophtha.2023.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 10/05/2023] [Indexed: 12/28/2023] Open
Abstract
PURPOSE To review the published literature evaluating the visual and refractive outcomes and rotational stability of eyes implanted with toric monofocal intraocular lenses (IOLs) for the correction of keratometric astigmatism during cataract surgery and to compare those outcomes with outcomes of eyes implanted with nontoric monofocal IOLs and other astigmatism management methods performed during cataract surgery. This assessment was restricted to the toric IOLs available in the United States. METHODS A literature search of English-language publications in the PubMed database was last conducted in July 2022. The search identified 906 potentially relevant citations, and after review of the abstracts, 63 were selected for full-text review. Twenty-one studies ultimately were determined to be relevant to the assessment criteria and were selected for inclusion. The panel methodologist assigned each a level of evidence rating; 12 studies were rated level I and 9 studies were rated level II. RESULTS Eyes implanted with toric IOLs showed excellent postoperative uncorrected distance visual acuity (UCDVA), reduction of postoperative refractive astigmatism, and good rotational stability. Uncorrected distance visual acuity was better and postoperative cylinder was lower with toric IOLs, regardless of manufacturer, when compared with nontoric monofocal IOLs. Correcting pre-existing astigmatism with toric IOLs was more effective and predictable than using corneal relaxing incisions (CRIs), especially in the presence of higher magnitudes of astigmatism. CONCLUSIONS Toric monofocal IOLs are effective in neutralizing pre-existing corneal astigmatism at the time of cataract surgery and result in better UCDVA and significant reductions in postoperative refractive astigmatism compared with nontoric monofocal IOLs. Toric IOLs result in better astigmatic correction than CRIs, particularly at high magnitudes of astigmatism.

Trabecular Procedures Combined with Cataract Surgery for Open-Angle Glaucoma: A Report by the American Academy of Ophthalmology. Ophthalmology 2024; 131:370-382. [PMID: 38054909 DOI: 10.1016/j.ophtha.2023.10.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 10/05/2023] [Accepted: 10/05/2023] [Indexed: 12/07/2023] Open
Abstract
PURPOSE To determine the intraocular pressure (IOP) reduction of various trabecular procedures (a form of minimally invasive glaucoma surgery [MIGS]) combined with cataract surgery compared with cataract surgery alone, to compare the safety of the various trabecular procedures, and to highlight patient characteristics that may favor one trabecular procedure over another. METHODS A search of English-language peer-reviewed literature in the PubMed database was initially conducted in February 2021 and updated in April 2023. This yielded 279 articles. Twenty studies met initial inclusion and exclusion criteria and were assessed for quality by the panel methodologist. Of these, 10 were rated level I, 3 were rated level II, and 7 were rated level III. Only the 10 level I randomized controlled trials (RCTs) were included in this assessment, and all were subject to potential industry-sponsorship bias. RESULTS The current analysis focuses on the amount of IOP reduction (in studies that involved medication washout) and on IOP reduction with concurrent medication reduction (in studies that did not involve medication washout). Based on studies that performed a medication washout, adding a trabecular procedure to cataract surgery provided an additional 1.6 to 2.3 mmHg IOP reduction in subjects with hypertensive, mild to moderate open-angle glaucoma (OAG) at 2 years over cataract surgery alone, which itself provided approximately 5.4 to 7.6 mmHg IOP reduction. In other words, adding a trabecular procedure provided an additional 3.8% to 8.9% IOP reduction over cataract surgery alone, which itself provided 21% to 28% IOP reduction. There was no clear benefit of one trabecular procedure over another. Patient-specific considerations that can guide procedure selection include uveitis predisposition, bleeding risk, metal allergy, and narrowing of Schlemm's canal. There are no level I data on the efficacy of trabecular procedures in subjects with pretreatment IOP of 21 mmHg or less. CONCLUSIONS Trabecular procedures combined with cataract surgery provide an additional mild IOP reduction over cataract surgery alone in hypertensive OAG subjects. Additional research should standardize outcome definitions, avoid industry sponsorship bias, and study the efficacy of these procedures in normotensive OAG.

Aqueous Shunts with Extraocular Reservoir for Open-Angle Adult Glaucoma: A Report by the American Academy of Ophthalmology. Ophthalmology 2024; 131:227-239. [PMID: 38069945 DOI: 10.1016/j.ophtha.2023.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 10/05/2023] [Accepted: 10/05/2023] [Indexed: 01/23/2024] Open
Abstract
PURPOSE To evaluate the recently published literature on the efficacy and safety of the use of aqueous shunts with extraocular reservoir for the management of adult open-angle glaucomas (OAGs). METHODS A search of peer-reviewed literature was last conducted in April 2023 of the PubMed database and included only articles published since the last aqueous shunt Ophthalmic Technology Assessment, which assessed articles published before 2008. The abstracts of these 419 articles were examined, and 58 studies were selected for full-text analysis. After inclusion and exclusion criteria were applied, 28 articles were selected and assigned ratings by the panel methodologist according to the level of evidence. Twenty-five articles were rated level I and 3 articles were rated level II. There were no level III articles. RESULTS Implantation of aqueous shunts with extraocular reservoir can lower intraocular pressure (IOP) by between one-third and one-half of baseline IOP, depending on whether it is undertaken as the primary or secondary glaucoma surgery. Success rates for aqueous shunts were found to be better than for trabeculectomies in eyes with prior incisional surgery. Conversely, in eyes without prior incisional surgery, implantation of aqueous shunts was found to have an overall lower success rate as the primary glaucoma procedure compared with trabeculectomy. Although both valved and nonvalved aqueous shunts with extraocular reservoir were effective, the nonvalved device generally achieved slightly lower long-term IOPs with fewer glaucoma medications and less need for additional glaucoma surgery. Both devices slow the rates of visual field progression with efficacy comparable with that of trabeculectomy. Early aqueous humor suppression after aqueous shunt implantation is recommended for the management of the postoperative hypertensive phase and long-term IOP control. No strong evidence supports the routine use of mitomycin C with aqueous shunt implantation for OAG. CONCLUSIONS Implantation of aqueous shunts with extraocular reservoir, including valved or nonvalved devices, has been shown to be an effective strategy to lower IOP. Strong level I evidence supports the use of aqueous shunts with extraocular reservoir by clinicians for the management of adult OAG.

Abstract
PURPOSE To evaluate the current published literature on the utility of the 10-2 visual field (VF) testing strategy for the evaluation and management of early glaucoma, defined here as mean deviation (MD) better than -6 decibels (dB). METHODS A search of the peer-reviewed literature was last conducted in June 2023 in the PubMed database. Abstracts of 986 articles were examined to exclude reviews and non-English-language articles. After inclusion and exclusion criteria were applied, 26 articles were selected, and the panel methodologist rated them for strength of evidence. Thirteen articles were rated level I, and 8 articles were rated level II. The 5 level III articles were excluded. Data from the 21 included articles were abstracted and reviewed. RESULTS The central 12 locations on the 24-2 VF test grid lie within the central 10 degrees covered by the 10-2 VF test. In early glaucoma, defects detected within the central 10 degrees generally agree between the 2 tests. Defects within the central 10 degrees of the 24-2 VF test can predict defects on the 10-2 VF test, although the 24-2 may miss defects detected on the 10-2 VF test. In addition, results from the 10-2 VF test show better association with findings from OCT scans of the macular ganglion cell complex. Modifications of the 24-2 test that include extra test locations within the central 10 degrees improve detection of central defects found on 10-2 VF testing. CONCLUSIONS Evidence to date does not support routine testing using 10-2 VF for patients with early glaucoma. However, early 10-2 VF testing may provide sufficient additional information for some patients, particularly those with a repeatable defect within the central 12 locations of the standard 24-2 VF test or who have inner retinal layer thinning on OCT scans of the macula.

Abstract
OBJECTIVES This study explored factors related to Korean adults' smoking patterns and also the reasons for using new types of tobacco products. STUDY DESIGN Cross-sectional survey. METHODS Data from the Korea National Health and Nutrition Examination Survey from 2013 to 2021 were used. The prevalence of the use of electronic cigarettes (e-cigarettes) or heated tobacco products (HTPs) alone or in combination with conventional cigarettes (CC) and the reasons for using new tobacco products are presented. Factors associated with using new types of tobacco products alone or in combination with CC compared to exclusive CC users were identified using multinomial logistic regression analysis. RESULTS The prevalence of current smoking was 25.54% in 2013 and 23.05% in 2021, with no significant change. The prevalence of CC decreased from 23.39% in 2013 to 15.77% in 2021. The prevalence of new tobacco use in combination with CC did not show a definite trend. The prevalence of exclusive use of new tobacco was <1% until 2018 and has rapidly increased thereafter. Of the HTPs users, 46.68% responded with 'no cigarette smell' as the main reason for HTPs use, followed by 'It seems less harmful than cigarette' (19.19%), and 'It seems to be helpful for quitting smoking' (15.04%). Of the e-cigarette users, 45.19% responded 'It seems to be helpful for quitting smoking' as the main reason for e-cigarette use, followed by 'It is less harmful than cigarettes' (19.98%). Compared to CC users, new tobacco users were younger, had a higher household income or education, and used more nutritional supplements. CONCLUSION Regulations for newer tobacco products are more lenient than for traditional cigarettes, leading to misunderstandings, especially among women and young people. To increase awareness of the risks of these products, specific policies such as disclosure of ingredients, ban on online sales, and increase in consumption tax, are needed.

Selective Laser Trabeculoplasty for the Treatment of Glaucoma: A Report by the American Academy of Ophthalmology. Ophthalmology 2024; 131:37-47. [PMID: 37702635 DOI: 10.1016/j.ophtha.2023.07.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 07/31/2023] [Accepted: 07/31/2023] [Indexed: 09/14/2023] Open
Abstract
PURPOSE To review the current published literature for high-quality studies on the use of selective laser trabeculoplasty (SLT) for the treatment of glaucoma. This is an update of the Ophthalmic Technology Assessment titled, "Laser Trabeculoplasty for Open-Angle Glaucoma," published in November 2011. METHODS Literature searches in the PubMed database in March 2020, September 2021, August 2022, and March 2023 yielded 110 articles. The abstracts of these articles were examined to include those written since November 2011 and to exclude reviews and non-English articles. The panel reviewed 47 articles in full text, and 30 were found to fit the inclusion criteria. The panel methodologist assigned a level I rating to 19 studies and a level II rating to 11 studies. RESULTS Data in the level I studies support the long-term effectiveness of SLT as primary treatment or as a supplemental therapy to glaucoma medications for patients with open-angle glaucoma. Several level I studies also found that SLT and argon laser trabeculoplasty (ALT) are equivalent in terms of safety and long-term efficacy. Level I evidence indicates that perioperative corticosteroid and nonsteroidal anti-inflammatory drug eye drops do not hinder the intraocular pressure (IOP)-lowering effect of SLT treatment. The impact of these eye drops on lowering IOP differed in various studies. No level I or II studies exist that determine the ideal power settings for SLT. CONCLUSIONS Based on level I evidence, SLT is an effective long-term option for the treatment of open-angle glaucoma and is equivalent to ALT. It can be used as either a primary intervention, a replacement for medication, or an additional therapy with glaucoma medications.

[PMID: 37991790 PMCID: PMC10666044 DOI: 10.1001/jamaophthalmol.2023.5386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Accepted: 10/01/2023] [Indexed: 11/23/2023]
Abstract
Importance The number of syphilis cases continues to increase in the US every year since 2001 with a 74% increase observed since 2017. In addition, there remains a national shortage of injectable penicillin G. Despite the increase in reported cases, to the authors' knowledge, there has been no recent nationwide study investigating the trends in incidence of syphilitic uveitis. Objective To evaluate the national and regional incidence of syphilitic uveitis-related hospitalizations in the US. Design, Setting, and Participants This was a retrospective, cross-sectional study. The Nationwide Inpatient Sample was queried to identify all inpatient admissions with a diagnosis of syphilitic uveitis in the US between the years 2010 and 2019. Analyses were performed to determine baseline sociodemographic characteristics and identify national and regional trends in incidence. All patients hospitalized with a diagnosis of syphilis, uveitis, and/or syphilitic uveitis were eligible for inclusion. Statistical analysis of study data took place in June 2023. Exposure Diagnosis of syphilis, uveitis, and/or syphilitic uveitis on inpatient admissions during the years 2010 to 2019 in the Nationwide Inpatient Sample. Main Outcome Measures The primary outcome was to determine trends in the national and regional incidence of syphilitic uveitis-related hospitalizations in the US. Secondary outcome measures included sociodemographic characteristics of patients with syphilitic uveitis, incidence stratified by sex and race and ethnicity, and median charge per syphilitic uveitis hospital admission. Results From the Nationwide Inpatient Sample, inpatient data from 444 674 patients (median [IQR] age, 53 [37-67] years; 54.8% male) were analyzed. There were an estimated 5581 syphilitic uveitis-related hospitalizations during the 10-year study period. The median (IQR) age of individuals with syphilitic uveitis was 45 (35-55) years, and 4395 patients (78.9%) were male. Syphilitic uveitis disproportionately affected African American individuals (1787 patients [32%], although they compose 13.6% of the population) and those belonging to the lowest median household income quartile (2163 [38.8%]). The national incidence was 0.15 per 100 000 population and showed an increasing trend over the years, with the lowest incidence in 2011 (0.08 per 100 000 population) and the highest incidence in 2019 (0.23 per 100 000 population; P = .04). Regional analysis showed an increase in incidence across all 4 US geographical regions. A total of 1293 patients (23.2%) had comorbid AIDS. Conclusion and Relevance Although this cross-sectional study only captured inpatient diagnosis, an increasing incidence of syphilitic uveitis-related hospitalizations was observed in the US between 2010 and 2019. Given the concomitant national shortage of injectable penicillin G, results suggest that clinicians should maintain a high index of suspicion for syphilis when evaluating patients with intraocular inflammation.

Advanced Corneal Imaging in Keratoconus: A Report by the American Academy of Ophthalmology. Ophthalmology 2024; 131:107-121. [PMID: 37855776 DOI: 10.1016/j.ophtha.2023.07.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 07/31/2023] [Accepted: 07/31/2023] [Indexed: 10/20/2023] Open
Abstract
PURPOSE To review the published literature on the diagnostic capabilities of the newest generation of corneal imaging devices for the identification of keratoconus. METHODS Corneal imaging devices studied included tomographic platforms (Scheimpflug photography, OCT) and functional biomechanical devices (imaging an air impulse on the cornea). A literature search in the PubMed database for English language studies was last conducted in February 2023. The search yielded 469 citations, which were reviewed in abstract form. Of these, 147 were relevant to the assessment objectives and underwent full-text review. Forty-five articles met the criteria for inclusion and were assigned a level of evidence rating by the panel methodologist. Twenty-six articles were rated level II, and 19 articles were rated level III. There were no level I evidence studies of corneal imaging for the diagnosis of keratoconus found in the literature. To provide a common cross-study outcome measure, diagnostic sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) were extracted. (A perfect diagnostic test that identifies all cases properly has an AUC of 1.0.) RESULTS: For the detection of keratoconus, sensitivities for all devices and parameters (e.g., anterior or posterior corneal curvature, corneal thickness) ranged from 65% to 100%. The majority of studies and parameters had sensitivities greater than 90%. The AUCs ranged from 0.82 to 1.00, with the majority greater than 0.90. Combined indices that integrated multiple parameters had an AUC in the mid-0.90 range. Keratoconus suspect detection performance was lower with AUCs ranging from 0.66 to 0.99, but most devices and parameters had sensitivities less than 90%. CONCLUSIONS Modern corneal imaging devices provide improved characterization of the cornea and are accurate in detecting keratoconus with high AUCs ranging from 0.82 to 1.00. The detection of keratoconus suspects is less accurate with AUCs ranging from 0.66 to 0.99. Parameters based on single anatomic locations had a wide range of AUCs. Studies with combined indices using more data and parameters consistently reported high AUCs.

Improved diagnostic performance of susceptibility-weighted imaging with compressed sensing-sensitivity encoding and neuromelanin-sensitive MRI for Parkinson's disease and atypical Parkinsonism. Clin Radiol 2024; 79:e102-e111. [PMID: 37863747 DOI: 10.1016/j.crad.2023.09.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 08/08/2023] [Accepted: 09/18/2023] [Indexed: 10/22/2023]
Abstract
AIM To verify the diagnostic performance of the loss of nigrosome-1 on susceptibility-weighted imaging (SWI) with compressed sensing-sensitivity encoding (CS-SENSE) and neuromelanin on neuromelanin-sensitive (NM) magnetic resonance imaging (MRI) for the diagnosis of Parkinson's disease (PD) and atypical Parkinsonism. MATERIALS AND METHODS A total of 195 patients who underwent MRI between October 2019 and February 2020, including SWI, with or without CS-SENSE, and NM-MRI, were reviewed retrospectively. Two neuroradiologists assessed the loss of nigrosome-1 on SWI and neuromelanin on the NM-MRI. The result of N-3-fluoropropyl-2-beta-carbomethoxy-3-beta-(4-iodophenyl) nortropane positron-emission tomography (PET) was set as the reference standard. RESULTS When CS-SENSE was applied for nigrosome-1 imaging on SWI, the non-diagnostic scan rate was lowered significantly from 19.3% (17/88) to 5.6% (6/107; p=0.004). Diagnosis of PD and atypical Parkinsonism based on the loss of nigrosome-1 on SWI and based on NM-MRI showed good diagnostic value (area under the curve [AUC] 0.821, 95% confidence interval [CI] = 0.755-0.875: AUC 0.832, 95% CI = 0.771-0.882, respectively) with a substantial inter-reader agreement (κ = 0.791 and 0.681, respectively). Combined SWI and neuromelanin had a similar discriminatory ability (AUC 0.830, 95% CI = 0.770-0.880). Similarly, the diagnosis of PD was excellent. CONCLUSIONS CS-SENSE may add value to the diagnostic capability of nigrosome-1 on SWI to reduce the nondiagnostic scan rates. Furthermore, loss of nigrosome-1 on SWI or volume loss of neuromelanin on NM-MRI may be helpful for diagnosing PD.

Thermal Pulsation in the Management of Meibomian Gland Dysfunction and Dry Eye: A Report by the American Academy of Ophthalmology. Ophthalmology 2023; 130:1336-1341. [PMID: 37642619 DOI: 10.1016/j.ophtha.2023.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 07/12/2023] [Indexed: 08/31/2023] Open
Abstract
PURPOSE To review the literature to determine the efficacy and safety of thermal pulsation technologies in improving signs or symptoms of meibomian gland dysfunction (MGD) and dry eye compared with no therapy or with conventional warm compress therapy or eyelid hygiene. METHODS A literature search was conducted in the PubMed database in June 2022 and again in March 2023 to identify all studies in the English language on the use of thermal pulsation to treat MGD or dry eye. The search yielded 59 citations, and 11 articles met all of the inclusion criteria. The panel methodologist then assigned a level of evidence rating for each study; 8 studies were rated level I evidence and 3 studies were rated level II evidence. RESULTS All included studies evaluated a single 12-minute session using the LipiFlow automated thermal pulsation system (TearScience, Inc, or Johnson & Johnson). Improvements were detected in subjective and objective metrics of MGD or dry eye in patients within 1 to 12 months of thermal pulsation treatment compared with nontreatment. Most of the studies (9/11) reported greater efficacy with thermal pulsation than with standard warm compress therapy and eyelid hygiene. Four of these studies showed relevant industry conflicts of interest. Two of the 4 level I studies without direct industry participation concluded that thermal pulsation treatment was not significantly different from conventional hygiene or warm compress therapy control treatments (in symptoms in one of the studies and in objective findings in the second study). No serious adverse events were reported in any of the 11 studies. CONCLUSIONS According to the current literature, a single thermal pulsation session may improve subjective or objective parameters of MGD and dry eye safely. However, industry support and participation were present in 4 of the 8 level I studies. The durability beyond several months and cost efficacy remain uncertain. Because the inclusion parameters of this assessment captured only the LipiFlow system, the conclusions are limited to that product. High-quality independent studies are needed to assess the long-term benefits of this intervention.

Abstract
PURPOSE To review the published literature on the use of levodopa/carbidopa to augment the treatment of amblyopia. METHODS Literature searches for English language studies were last conducted in October 2022 in the PubMed database with no date restrictions. The combined searches yielded 55 articles, of which 23 were reviewed in full text. Twelve of these were considered appropriate for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. Nine studies were rated level I, and 3 studies were rated level II; there were no level III studies. RESULTS The duration of treatment was limited to 3 to 16 weeks because of concern about long-term adverse effects such as tardive dyskinesia. This complication was not reported in any of the study participants. The dose of levodopa ranged from 1.5 to 8.3 mg/kg/day, generally divided into 3 daily doses. The carbidopa dose was approximately 25% of the levodopa dose in all treatments. Evidence from these studies indicates that augmenting traditional patch occlusion therapy with the oral administration of levodopa/carbidopa can improve the vision of amblyopic children, but the effect was small (0.17-0.3 logarithm of the minimum angle of resolution [logMAR] units) and only statistically significant when compared with patching alone in 2 of the 12 studies cited. Regression of vision was reported in the majority of studies (9 of 12 reported; range, 0-0.17 logMAR unit regression) after discontinuation of therapy. Short-term side effects of the medications were not consistently reported but were most frequently mild and included headache and nausea. CONCLUSIONS The best available evidence is currently insufficient to show that augmenting amblyopia therapy using up to 16 weeks of levodopa/carbidopa will result in meaningful improvement in visual acuity. Given the potential for significant side effects such as tardive dyskinesia with long-term therapy, levodopa/carbidopa does not appear to be a viable option for amblyopia therapy FINANCIAL DISCLOSURE(S): The author(s) have no proprietary or commercial interest in any materials discussed in this article.

Use of Mitomycin C in Dacryocystorhinostomy: A Report by the American Academy of Ophthalmology. Ophthalmology 2023; 130:1212-1220. [PMID: 37656088 DOI: 10.1016/j.ophtha.2023.06.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/28/2023] [Accepted: 06/29/2023] [Indexed: 09/02/2023] Open
Abstract
PURPOSE To review the literature on the adjuvant use of mitomycin C (MMC) during dacryocystorhinostomy (DCR) in adults with primary nasolacrimal duct obstructions (NLDOs) to determine the efficacy in improving functional and anatomic outcomes with an acceptable level of risk. METHODS A literature search conducted in November 2020 and updated in November 2022 yielded 137 articles. Twenty-four articles met the inclusion criteria and were rated for level of evidence by the panel methodologist. Inclusion criteria required controlled studies on the effect of MMC on outcomes of external, endoscopic endonasal, or diode laser-assisted transcanalicular DCR in adults with primary acquired nasolacrimal obstruction with 6 months minimum follow-up and at least 10 participants. RESULTS Six of the 24 articles were rated level I evidence, 15 level II , and 3 level III. In primary external DCR, MMC significantly improved functional outcomes in 3 of 9 series. In primary endoscopic endonasal DCR, MMC significantly improved functional outcomes in 1 of 9 series. In revision endoscopic endonasal DCR, MMC significantly improved functional success in 1 of 3 series. The use of MMC did not improve outcomes statistically in any diode laser-assisted transcanalicular DCR studies. Concentrations of MMC ranged from 0.05 to 1 mg/ml, with 0.2 mg/ml used most frequently in 12 series, with duration of application ranging from 2 to 30 minutes. Ostium size was significantly larger in MMC groups than in control groups at 6 months after surgery in 4 of 5 reporting studies. However, these larger ostia did not confer higher functional success rates. Reporting of adverse events related to MMC were rare, with delayed cutaneous wound healing reported in 1 of 750 patients. CONCLUSIONS Intraoperative use of MMC in external and endoscopic endonasal DCR has been shown to improve functional and anatomic outcomes compared with controls in some series, but there is no agreement on the recommended concentration or application time for MMC in DCR. The data support that MMC use can result in a larger ostium size, decreased granulation tissue formation, and a decreased number of postoperative nasal debridements compared with controls, but this does not translate into improved functional success.

Intravitreal triple therapy with vancomycin, ceftazidime, and moxifloxacin for bacterial endophthalmitis: A Twelve-year experience. Graefes Arch Clin Exp Ophthalmol 2023; 261:2813-2819. [PMID: 37227476 DOI: 10.1007/s00417-023-06112-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 05/02/2023] [Accepted: 05/10/2023] [Indexed: 05/26/2023] Open
Abstract
PURPOSE Increasing rates of antibiotic resistance in endophthalmitis have been reported. This study examines outcomes of triple therapy with intravitreal vancomycin, ceftazidime, and moxifloxacin for endophthalmitis. METHODS Retrospective, consecutive series of all patients treated with abovementioned intravitreal antibiotics from January 2009 to June 2021. Percentages of eyes attaining greater than or equal to 20/200 and 20/50 Snellen visual acuities and adverse events were evaluated. RESULTS 112 eyes met inclusion criteria. 63 of 112 eyes (56%) achieved a visual acuity of 20/200 during follow-up, with 39 (35%) returning to at least 20/50. In subgroup analysis, 23 of 24 (96%) eyes with post-cataract endophthalmitis obtained ≥ 20/200 acuity and 21 of 24 (88%) obtained ≥ 20/50 acuity during follow-up. There were no cases of macular infarction. CONCLUSIONS Intravitreal moxifloxacin (160 µg/0.1 mL) was well tolerated as an adjunct to vancomycin and ceftazidime for bacterial endophthalmitis. Use of this novel combination offers several theoretical advantages compared to standard therapy with two antibiotics, including expanded gram-negative coverage and potential synergy, and may be particularly valuable in geographies where the local antibiogram supports empiric use. Further study is merited to verify the safety and efficacy profile.

Abstract
PURPOSE To review the published literature assessing the clinical utility of genetic testing in individuals with infantile nystagmus syndrome (INS), defined as binocular conjugate nystagmus and onset prior to 6 months of age, with or without associated findings. METHODS A literature search was last conducted in October 2022. The results were limited to articles published in English. The search yielded 517 abstracts, of which 72 papers were reviewed in full text. Of these papers, 4 met the criteria for inclusion and were graded by a study methodologist. RESULTS The 4 studies that met inclusion criteria used next-generation sequencing with gene panels ranging from 31 to 336 genes. The overall molecular diagnostic rate ranged from 35% to 60% in the included studies, although the yield was higher when genetic testing was guided by clinical phenotyping (approximately 80%) and in the subsets of patients with a family history (up to 88%). As many as 30% of patients tested had a reclassification of the diagnosis based on the genetic testing results. CONCLUSIONS Genetic testing has the potential to provide a definitive diagnosis and identify treatable conditions in patients presenting with INS, especially when considered in conjunction with clinical phenotyping and family history.

Abstract
PURPOSE To review the current published literature on the utility of corneal hysteresis (CH) to assist the clinician in the diagnosis of glaucoma or in the assessment of risk for disease progression in existing glaucoma patients. METHODS Searches of the peer-reviewed literature in the PubMed database were performed through July 2022. The abstracts of 423 identified articles were examined to exclude reviews and non-English articles. After inclusion and exclusion criteria were applied, 19 articles were selected, and the panel methodologist rated them for level of evidence. Eight articles were rated level I, and 5 articles were rated level II. The 6 articles rated level III were excluded. RESULTS Corneal hysteresis is lower in patients with primary open-angle glaucoma, primary angle-closure glaucoma, pseudoexfoliative glaucoma, and pseudoexfoliation syndrome compared with normal subjects. Interpretation of low CH in patients with high intraocular pressure (IOP) or on topical hypotensive medications is complicated by the influence of these parameters on CH measurements. However, CH is also lower in treatment-naïve, normal-tension glaucoma patients compared with normal subjects who have a similar IOP. In addition, lower CH is associated with an increased risk of progression of glaucoma based on visual fields or structural markers in open-angle glaucoma patients, including those with apparently well-controlled IOP. CONCLUSIONS Corneal hysteresis is lower in glaucoma patients compared with normal subjects, and lower CH is associated with an increased risk of disease progression. However, a causal relationship remains to be demonstrated. Nevertheless, measurement of CH complements current structural and functional assessments in determining disease risk in glaucoma suspects and patients.

Abstract
Denosumab is an effective antiresorptive drug commonly prescribed for the treatment of osteoporosis. However, some patients do not respond well to denosumab treatment. The aim of this study was to evaluate the factors underlying treatment nonresponses to denosumab in elderly patients following hip fracture. This retrospective study included 130 patients treated with denosumab after osteoporotic hip fracture between March 2017 and March 2020. The patients were categorized as denosumab nonresponders if they had a T-score <-3 that persisted between dual-energy X-ray absorptiometry scans, a >3% decrease in bone mineral density (BMD), or an incident fracture on denosumab therapy. We examined the baseline characteristics associated with blunted BMD responses and compared the groups following denosumab treatment for 12 months. Of 130 patients with baseline data, 105 patients (80.8%) were considered responders. No difference in baseline vitamin D, calcium, BMI, age, gender, prior fracture history, or bisphosphonate use was observed between responders and nonresponders. A longer interval between denosumab injections was associated with suboptimal BMD response at both spine and total hip (p<0.001 and p=0.04, respectively). The overall L-BMD and H-BMD were significantly increased compared with pretreatment levels after denosumab treatment (5.7% and 2.5%, respectively). This study revealed that nonresponse was not strongly associated with certain baseline variables and it appears that the reponders and nonresponders were reasonably comparable in this study population. The results of our study highlight the importance of timely denosumab administration when using this drug for osteoporosis management. Physicians should keep these results in mind in clinical practice so that they can improve utilization of 6-month denosumab.

Abstract
PURPOSE To review the literature on the efficacy of surgical procedures to improve visual acuity (VA) in patients with infantile nystagmus syndrome (INS). METHODS Literature searches were last conducted in January 2022 in the PubMed database for English-language studies with no date restrictions. The combined searches yielded 354 abstracts, of which 46 were reviewed in full text. Twenty-three of these were considered appropriate for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. RESULTS One included study was a randomized trial; the remaining 22 were case series. The 23 studies included children and adults with INS and a variable proportion with anomalous head position (AHP), strabismus, and sensory diagnoses. The surgical interventions evaluated included large recessions, tenotomy and reattachment (TAR), myectomy with or without pulley fixation, and anterior extirpation of the 4 horizontal rectus muscles, as well as various procedures to correct an AHP in which VA was reported as a secondary outcome. The data were mixed, with improvements in binocular best-corrected visual acuity (BCVA) ranging from no improvement to 0.3 logarithm of the minimum angle of resolution (logMAR), or 3 lines. (Most studies were in the range of 0.05-0.2 logMAR.) Statistically significant improvement in VA was noted in 12 of 16 studies (75%) that performed statistical analyses, with no clear advantage of any single procedure. Complications and reoperations were lowest in patients who underwent TAR and highest in those who underwent myectomy or anterior extirpation. CONCLUSIONS The best available evidence suggests that eye muscle surgery in patients with INS results in a modest improvement in VA.

Abstract
OBJECTIVE To evaluate current best practices for postoperative photorefractive keratectomy (PRK) pain control. METHODS Literature searches in the PubMed database were last conducted in October 2021 and were restricted to publications in English. This search identified 219 citations, of which 84 were reviewed in full text for their relevance to the scope of this assessment. Fifty-one articles met the criteria for inclusion; 16 studies were rated level I, 33 studies were rated level II, and 2 studies were rated level III. RESULTS Systemic opioid and nonsteroidal anti-inflammatory drugs (NSAIDs); topical NSAIDs; postoperative cold patches; bandage soft contact lenses (BCLs), notably senofilcon A contact lenses; and topical anesthetics were demonstrated to offer significantly better pain control than comparison treatments. Some other commonly reported pain mitigation interventions such as systemic gabapentinoids, chilled intraoperative balanced salt solution (BSS) irrigation, cycloplegia, and specific surface ablation technique strategies offered limited improvement in pain control over control treatments. CONCLUSIONS Systemic NSAIDs and opioid medications, topical NSAIDs, cold patches, BCLs, and topical anesthetics have been shown to provide improved pain control over alternative strategies and allow PRK-associated pain to be more tolerable for patients.

Detection rate of MR myelography without intrathecal gadolinium in patients with newly diagnosed spontaneous intracranial hypotension. Clin Radiol 2022; 77:848-854. [PMID: 35985843 DOI: 10.1016/j.crad.2022.06.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 06/16/2022] [Accepted: 06/28/2022] [Indexed: 11/26/2022]
Abstract
AIM To evaluate the detection rate of magnetic resonance (MR) myelography without intrathecal gadolinium for cerebrospinal fluid (CSF) leakage in patients with newly diagnosed spontaneous intracranial hypotension (SIH) and to validate a published scoring system for predicting CSF leakage. MATERIALS AND METHODS This retrospective, observational, single-institution study included patients with newly diagnosed SIH between March 2015 and April 2021. Patients were included if they (a) had newly diagnosed SIH and (b) underwent initial brain MR imaging and preprocedural MR myelography with two- and three-dimensional turbo spin-echo sequences. Patients who underwent spine surgery or procedures including epidural injection and acupuncture were excluded. The detection rate was defined as the proportion of patients with a true-positive MR myelography result among all patients with confirmed CSF leakage. The interobserver agreement for the MR myelography results between two radiologists was analysed using weighted kappa statistics. RESULTS A total of 136 patients (mean age, 48 years; 70 women) with suspected SIH were included. Of these patients, 120 (88%, 120/136) were confirmed to have CSF leakage. Of the patients with confirmed CSF leakage, 90 (75%, 90/120) had epidural fluid collection. The detection rate of MR myelography for CSF leakage was 88% (105/120). The interobserver agreement between the two readers for detecting CSF leakage (κ = 0.76) or epidural fluid collection (κ = 0.76) on MR myelography was high. Among 24 patients with normal brain MR imaging results, 16 had CSF leakage (67%, 16/24). CONCLUSIONS Non-invasive MR myelography without intrathecal gadolinium should be considered to detect CSF leakage in patients with suspected SIH.

Effectiveness of Laser Refractive Surgery to Address Anisometropic Amblyogenic Refractive Error in Children: A Report by the American Academy of Ophthalmology. Ophthalmology 2022; 129:1323-1331. [PMID: 35987663 PMCID: PMC9982261 DOI: 10.1016/j.ophtha.2022.06.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 06/22/2022] [Accepted: 06/22/2022] [Indexed: 12/31/2022] Open
Abstract
PURPOSE To review the published literature assessing the safety and effectiveness of laser refractive surgery to treat anisometropic amblyogenic refractive error in children aged ≤ 18 years. METHODS A literature search of the PubMed database was conducted in October 2021 with no date limitations and restricted to publications in English. The search yielded 137 articles, 69 of which were reviewed in full text. Eleven articles met the criteria for inclusion and were assigned a level of evidence rating. RESULTS The 11 included articles were all level III evidence and consisted of 1 case-control study and 10 case series. Six studies used laser-assisted in situ keratomileusis (LASIK), 1 used photorefractive keratectomy (PRK), 1 used refractive lenticule extraction/small incision lenticule extraction, and the rest used a combination of LASIK, PRK, laser epithelial keratomileusis (LASEK), or refractive lenticule extraction/small incision lenticule extraction. Five studies enrolled patients with anisometropic myopia, 2 studies enrolled patients with anisometropic hyperopia, and the remainder were mixed. Although all studies demonstrated an improvement in best-corrected visual acuity (BCVA), the magnitude of improvement varied widely. As study parameters varied, a successful outcome was defined as residual refractive error of 1 diopter (D) or less of the target refraction because this was the most commonly used metric. Successful outcomes ranged between 38% and 87%, with a mean follow-up ranging from 4 months to 7 years. Despite this wide range, all studies demonstrated an improvement in the magnitude of anisometropia. Regression in refractive error occurred more frequently and to a greater degree in myopic eyes and eyes with longer follow-up, and in younger patients. Although one study reported 2 free flaps, most studies reported no serious adverse events. The most common complications were corneal haze and striae. CONCLUSIONS Findings from included studies suggest that laser refractive surgery may address amblyogenic refractive error in children and that it appears to decrease anisometropia. However, the evidence for improvement in amblyopia is unclear and long-term safety data are lacking. Long-term data and well-designed clinical studies that use newer refractive technologies in standardized patient populations would help address the role of refractive surgery in children and its potential impact on amblyopia.

Abstract
Abstract
Background
Multiple stenting in the chronic total occlusion (CTO) lesions is frequently required, however associated with poorer clinical outcomes. It is demonstrated that intravascular ultrasound (IVUS)-guided CTO-percutaneous coronary intervention (PCI) is related to a lower risk of adverse clinical events.
Purpose
We aimed to evaluate the clinical impact of stent optimization under IVUS guidance for multiple stenting, comparing with single stenting.
Methods
A total of 916 patients receiving drug-eluting stent (DES) under IVUS guidance were classified into two groups (stent optimization and non-optimization) according to optimization criteria (an absolute expansion criteria; minimal stent area ≥4.9 mm2 and a relative expansion criteria; 80% of mean reference lumen area). Of total population, 314 patients (34.3%) were treated with single stent and 575 patients (62.7%) were treated with multiple stents, respectively. Ischemic-driven target-lesion revascularization (TLR)/reocclusion was evaluated.
Results
Under IVUS guidance, 316 patients (34.5%) met IVUS criteria for stent optimization The achieving rates were 53% in the single stent group and 24% in the multiple stents group, respectively, (p<0.001). During a median of 4.7 years, the multiple stent group showed a significantly higher TLR/reocclusion rate, compared with the single stent group (12.8% vs. 5.2%, adjusted hazard ratio [HR] 2.51, 95% confidence interval [CI] 1.20–5.25, p=0.01). (Figure 1) Meeting both the absolute and relative expansion criteria was associated with a significantly low rate of TLR/reocclusion rate (12.5% vs. 5.2%, adjusted HR 0.34, 95% CI: 0.15–0.79, p=0.01). Under IVUS-guidance, there was no significant difference between multiple stenting and single stenting in case of achieving the optimization criteria (6.5% vs. 4.2%, p=0.11), whereas non-optimization group in the patients with multiple stenting showed a significantly higher rate of TLR/reocclusion, compared with IVUS-optimization group in the patients with single stenting (14.5% vs. 4.2%, p=0.002). (Figure 2)
Conclusions
In CTO-PCI with DES, multiple stenting significantly increased the risk of TLR/reocclusion. IVUS-guided optimization for multiple stenting showed a comparable long-term risk of TLR/reocclusion to single stenting with IVUS optimization. Hence, achieving IVUS expansion criteria may help to reduce the risk of TLR/reocclusion in CTO-PCI with multiple DES overlapping.

Functional analysis of novel SCN5A mutations related to Brugada syndrome. Eur Heart J 2022.

Abstract
Abstract
Brugada syndrome (BrS) is an arrhythmogenic disorder that has been linked to mutations in SCN5A, the gene encoding for the pore-forming α-subunit of the cardiac Na+ channel. Recently, novel SCN5A missense mutations (A385T and R504T) were identified in a BrS patient. Since the mutations are in the loop connecting transmembrane segments 5 and 6 in domain 1 (S5-S6 in DI) and segments 6 and 1 between domain 1 and 2 (DI-DII linker), it can lead to dysfunctional property of the Na+ channel. Here we aimed to characterize the electrophysiological properties of A385T and R504T. The wild-type (WT) and mutant SCN5A were transiently transfected in HEK293 cells, and the Na+ channel was analyzed using the whole-cell patch-clamp technique. WT, A385T, R504T, and double mutant (A385T/R504T) showed no significant differences in the current density and the voltage-dependent activation. Unexpectedly, a rightward shift of the voltage-dependent inactivation was identified in the three groups of mutation. Besides, the recovery from inactivation of double mutant was faster than that of WT. These results suggest that, contrary to the expected mechanism of BrS, the mutations cause a gain-of-function of NaV1.5. However, the current densities of R504T and double mutant transfected with β-subunit SCN1B were significantly suppressed but A385T was not different from WT. The voltage dependent activation and inactivation of all mutants were not significantly different from WT. The recovery from inactivation of all mutants were slower than that of WT. These results suggest that R504T mutation of α-subunit SCN5A interacting with β-subunit SCN1B is responsible to pathophysiological function of novel BrS.

Abstract
OBJECTIVE Multisystem inflammatory syndrome in children (MIS-C) can occur in association with coronavirus disease 2019 (COVID-19). It is not easy to differentiate MIS-C from severe COVID-19 or Kawasaki disease based on symptoms. The aim of this study was to describe the clinical and laboratory characteristics of MIS-C. PATIENTS AND METHODS We searched PubMed/Medline for case series and reports of MIS-C published until June 20, 2020. From a total of nine articles involving 45 cases, various clinical and laboratory data were extracted. Each target case was evaluated by using different diagnostic criteria. RESULTS The average age at onset of MIS-C was 8.6 years. In 80% of cases, the age of patients ranged from 5 to 15 years. Fever (100%) and shock (82%) were the most common presenting symptoms. Sixty percent of cases met the diagnostic criteria for typical or atypical Kawasaki disease. Biomarkers indicative of inflammation, coagulopathy, or cardiac injury were characteristically elevated as follows: ferritin (mean: 1,061 ng/mL), CRP (217 mg/L), ESR (69 mm/hr), IL-6 (214.8 pg/mL), TNFα (63.4 pg/mL), D-dimer (3,220 ng/mL), PT (15.5 s), troponin I (1,006 ng/L), and BNP (12,150 pg/mL). Intravenous immunoglobulin was administered in all target cases, and inotropic agents were commonly used as well. No case of death was observed. CONCLUSIONS This study demonstrated that MIS-C is a serious condition that presents with fever, rash, as well as cardiovascular and gastrointestinal symptoms. Although it is challenging to differentiate MIS-C from Kawasaki disease or severe COVID-19, initiation of appropriate treatments through early diagnosis is warranted.

Abstract
PURPOSE To elucidate strategies for and controversies surrounding the use of anti-inflammatory medications after uneventful cataract surgery, with a focus on the prevention of irreversible vision loss due to cystoid macular edema (CME). DESIGN Perspective. METHODS Expert commentary on the management of inflammation after cataract surgery. Discussion includes combination therapy with corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs), dosing strategies, and emerging therapies. RESULTS While prescribing both NSAIDs and corticosteroids for cataract surgery is common, these classes have overlapping mechanisms. Combination therapy may speed visual recovery, but there remains little evidence for improved long-term visual outcomes from NSAIDs. The last 2 decades have seen increasing data on potential benefits of pretreatment with NSAIDs 1-3 days prior to cataract surgery. Simultaneously, newly approved "dropless" delivery systems hold promise, and clinical trials are ongoing to assess outcomes of such formulations. CONCLUSIONS Optimal pharmacologic treatment for inflammation after cataract surgery remains controversial. A consensus definition for clinically significant CME may facilitate the comparison of anti-inflammatory drugs. And there remains a need for well-designed trials examining both topical and extended-release drug-delivery systems to refine the treatment paradigm.

Abstract
BACKGROUND Foreign bodies in the ear, nose and throat commonly necessitate emergency department visits. METHOD This retrospective study was conducted on emergency department visits from January 2010 to December 2019 to determine characteristics and clinical prognoses of ENT patients. Patients were divided into three groups according to foreign-body entry route; patient characteristics and clinical findings were compared between groups. RESULTS Of 676 142 emergency department visits, 10 454 were because of ENT-related foreign bodies. The mean (± standard deviation) age of subjects was 24.0 (± 23.4) years, and 5176 patients were male (49.5 per cent). The most common entry route was the mouth (74.5 per cent). Most patients (97.1 per cent) were discharged after emergency treatment. Intensive care and in-hospital mortality occurred only in the mouth group. CONCLUSION Clinical findings differ depending on foreign-body entry route. After emergency treatment, most patients were discharged; some cases presented serious complications.

Abstract
Purpose To analyze a series of eyes with brolucizumab-associated intraocular inflammation (IOI) without retinal vasculitis reported to the American Society of Retina Specialists (ASRS). Methods The ASRS Research and Safety in Therapeutics (ReST) Committee analyzed clinical characteristics from submitted reports of IOI after brolucizumab. Eyes with retinal vasculitis or that received intraocular antibiotics were excluded. Results Forty-nine eyes of 45 patients were collected. Mean visual acuity (VA) at baseline was 20/49 (range 20/20 - 5/200). Patients presented with IOI a mean of 24 (range 3-63) days after most recent brolucizumab injection; 61% presented for an unscheduled visit while 39% presented at routine follow-up. Mean VA at IOI presentation was 20/67 (range 20/20 - 3/200). Most common symptoms were floaters (78%) and blurry vision (76%). Pain (20%) and redness (16%) were less common; 3 (6%) eyes were asymptomatic. IOI was anterior only in 18%, posterior only in 31%, and both anterior and posterior in 51% of eyes. Treatment included topical steroids alone in 67% eyes, while 10% eyes received no treatment. Mean VA at last follow-up was 20/56 (range 20/20 - 1/200). Three (6%) eyes lost 3 or more lines and 1 (2%) eye lost 6 or more lines. Conclusions Brolucizumab-associated IOI without retinal vasculitis typically presented with a delayed onset of a few weeks. Often, visual acuity decline was relatively mild. Most symptoms resolved and nearly all had a return to baseline VA, but a small percentage of patients had a significant decrease in VA at last follow-up.

Abstract
PURPOSE To review the evidence on the safety and efficacy of current anti-vascular endothelial growth factor (VEGF) and intravitreal corticosteroid pharmacotherapies for the treatment of diabetic macular edema (DME). METHODS Literature searches were last conducted on May 13, 2020, in the PubMed database with no date restrictions and limited to articles published in English. The combined searches yielded 230 citations, of which 108 were reviewed in full text. Of these, 31 were deemed appropriate for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. RESULTS Only the 21 articles with level I evidence were included in this assessment. Seventeen articles provided level I evidence for 1 or more anti-VEGF pharmacotherapies, including ranibizumab (14), aflibercept (5), and bevacizumab (2) alone or in combination with other treatments for DME. Level I evidence was identified in 7 articles on intravitreal corticosteroid therapy for treatment of DME: triamcinolone (1), dexamethasone (4), and fluocinolone acetonide (2). CONCLUSIONS Review of the available literature indicates that intravitreal injections of anti-VEGF agents and corticosteroids are efficacious treatments for DME. Elevated intraocular pressure and cataract progression are important potential complications of corticosteroid therapy. Further evidence is required to assess the comparative efficacy of these therapies. Given the limited high-quality comparative efficacy data, choice of therapy must be individualized for each patient and broad therapeutic access for patients is critical to maximize outcomes.

Abstract
We investigated the anti-obesity effect and the underlying mechanisms of action of human-derived Limosilactobacillus fermentum MG4231, MG4244, and their combination, in high-fat diet-induced obese mice. Administration of the Limosilactobacillus strains decreased body weight gain, liver and adipose tissue weight, and glucose tolerance. Serum levels of total cholesterol, low-density lipoprotein-cholesterol, and leptin were reduced, while adiponectin increased. The administration of Limosilactobacillus strains improved the histopathological features of liver tissue, such as hepatic atrophy and inflammatory penetration, and significantly reduced the content of triglyceride in the liver. Limosilactobacillus administration discovered a significant reduction in the size of the adipocytes in the epididymal tissue. Limosilactobacillus treatment significantly reduced the expression of important regulators in lipid metabolism, including peroxisome proliferator-activated receptor γ, CCAAT/enhancer-binding protein α, fatty acid synthase (FAS), adipocyte-protein 2, and lipoprotein lipase in the epididymal tissue. Also, Limosilactobacillus lowered sterol regulatory element-binding protein 1-c and FAS in the liver tissue. Such changes in the expression of these regulators in both liver and epididymis tissue were caused by Limosilactobacillus upregulating phosphorylation of AMP-activated protein kinase and acetyl-CoA carboxylase. Therefore, we suggest that the use of the combination of L. fermentum MG4231 and MG4244, as probiotics could effectively inhibit adipogenesis and lipogenesis from preventing obesity.

Abstract
AimsRunning is the oldest form of exercise in human history and the most popular exercise in the world.1 While running can improve physical fitness and reduce chronic health problems such as obesity and cardiovascular disease, it is also associated with injuries in lower extremities.2 However, because there was no consensus definition of running-related injury, the prevalence and incidence of running-related injuries had been reported to vary between 19% and 92%.3 Moreover, epidemiology of running-related injuries in Asian populations has been rarely investigated. Therefore, this study was first to use the consensus definition of running-related injuries published in 20153 and investigated the epidemiology of running-related injuries in the Korean population.MethodsIn cross-sectional design, an online survey was circulated among various running communities in Korea. The questionnaire contained information on presence and location of pain attributed to running, demographic characteristics, weekly running mileage, training intensity, running pace, type of shoes, foot strike, reason for running, and exercise experience prior to running.ResultsAmong 1046 runners (male=624, female 422) who responded, 94.7% experienced some kind of pain while running, but only 37% were categorized to have running-related injuries. The most common site of injury was the knee followed by ankle. Exercise experience prior to running (OR 1.57 95% CI 1.13–2.21), setting of specific running goals (OR 1.57 95% CI 1.08–2.27), and mileage increases from 20–30 km to 30–40 km (OR 1.66 95% CI 1.06–2.63) were associated with significant increases in running-related injuries.ConclusionIn order to avoid running-related injuries, runners should be careful in increasing weekly mileage. Moreover, runners with previous exercise experience may need to approach running more cautiously. Setting goals may be motivating but at the same time can increase the risk of running-related injuries.ReferencesVidebæk S, Bueno AM, Nielsen RO, Rasmussen S.

Abstract
BACKGROUND Disproportionately enlarged subarachnoid space hydrocephalus is a specific radiologic marker for idiopathic normal pressure hydrocephalus. However, controversy exists regarding the prognostic utility of disproportionately enlarged subarachnoid space hydrocephalus. PURPOSE Our aim was to evaluate the prevalence of disproportionately enlarged subarachnoid space hydrocephalus in idiopathic normal pressure hydrocephalus and its predictive utility regarding prognosis in patients treated with ventriculoperitoneal shunt surgery. DATA SOURCES We used MEDLINE and EMBASE databases. STUDY SELECTION We searched for studies that reported the prevalence or the diagnostic performance of disproportionately enlarged subarachnoid space hydrocephalus in predicting treatment response. DATA ANALYSIS The pooled prevalence of disproportionately enlarged subarachnoid space hydrocephalus was obtained. Pooled sensitivity, specificity, and area under the curve of disproportionately enlarged subarachnoid space hydrocephalus to predict treatment response were obtained. Subgroup and sensitivity analyses were performed to explain heterogeneity among the studies. DATA SYNTHESIS Ten articles with 812 patients were included. The pooled prevalence of disproportionately enlarged subarachnoid space hydrocephalus in idiopathic normal pressure hydrocephalus was 44% (95% CI, 34%-54%). The pooled prevalence of disproportionately enlarged subarachnoid space hydrocephalus was higher in the studies using the second edition of the Japanese Guidelines for Management of Idiopathic Normal Pressure Hydrocephalus compared with the studies using the international guidelines without statistical significance (52% versus 43%, P = .38). The pooled sensitivity and specificity of disproportionately enlarged subarachnoid space hydrocephalus for prediction of treatment response were 59% (95% CI, 38%-77%) and 66% (95% CI, 57%-74%), respectively, with an area under the curve of 0.67 (95% CI, 0.63-0.71). LIMITATIONS The lack of an established method for assessing disproportionately enlarged subarachnoid space hydrocephalus using brain MR imaging served as an important cause of the heterogeneity. CONCLUSIONS Our meta-analysis demonstrated a relatively low prevalence of disproportionately enlarged subarachnoid space hydrocephalus in idiopathic normal pressure hydrocephalus and a poor diagnostic performance for treatment response.

PURPOSE To review the published literature assessing the efficacy and safety of presbyopia-correcting intraocular lenses (IOLs) for the treatment of presbyopia after cataract removal. METHODS Literature searches were undertaken in January 2018 and September 2020 in the PubMed, Medline, and Cochrane Library databases. This yielded 761 articles, of which 34 met the criteria for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. Thirteen studies were rated level I and 21 studies were rated level II. RESULTS Presbyopia-correcting lenses were effective at improving distance and near visual acuity after cataract surgery. Near acuity at different focal lengths was related directly to the effective add power of multifocal and extended depth-of-focus (EDOF) IOLs. Most multifocal and EDOF lenses that were compared with a control monofocal lens demonstrated that patient-reported spectacle independence was superior to the monofocal lens. All patients who had multifocal and EDOF lenses implanted showed decreased contrast sensitivity and reported more visual phenomena as compared with control participants who received monofocal lenses. CONCLUSIONS Presbyopia-correcting lenses improve uncorrected near and distance visual acuity and decrease spectacle dependence after cataract surgery. Mesopic contrast sensitivity is decreased compared with monofocal lenses, and patient-reported visual phenomena are more likely in patients receiving multifocal or EDOF lenses.

Abstract
PURPOSE To determine the rate of post-operative retinal detachment after elective pars plana vitrectomy for epiretinal membrane, and to test for the mitigating effect of prophylactic endolaser. METHODS We identified 459 eyes of 411 patients undergoing vitrectomy for epiretinal membrane at Vanderbilt University Medical Center between January 2010 and May 2017. Patients who underwent concurrent endolaser without any identified retinal break were included in the exposure cohort. Patients who underwent no prophylactic retinopexy or ablation were included in the unexposed cohort. Exposure data, demographic data, and outcome data were tabulated for comparison. RESULTS The final analysis included 343 eyes of 343 patients. Approximately 7% of eyes undergoing ERM surgery were found to have a full-thickness retinal break which was not seen preoperatively. The overall rate of postoperative RD was 2.04%. Postoperative retinal detachment occurred in 0 of the 34 eyes exposed to prophylactic laser, and in 7 of the 309 control eyes. Odds ratio was found to be 0.60 (p = 0.598 (95%CI 0.0327-10.7), p = 0.72), indicated the results were not statistically significant. DISCUSSION Looking at patients undergoing routine vitrectomy surgery for epiretinal membrane, no retinal detachments occurred in the group receiving prophylactic treatment, though this association did not reach statistical significance. With modern surgical techniques, post-operative retinal detachment remains relatively rare after vitrectomy for ERM though a thorough intraoperative exam is critical to identify occult retinal breaks.

Abstract
BACKGROUND AND PURPOSE Limited evidence has suggested that a deep learning automatic brain segmentation and classification method, based on T1-weighted brain MR images, can predict Alzheimer disease. Our aim was to develop and validate a deep learning-based automatic brain segmentation and classification algorithm for the diagnosis of Alzheimer disease using 3D T1-weighted brain MR images. MATERIALS AND METHODS A deep learning-based algorithm was developed using a dataset of T1-weighted brain MR images in consecutive patients with Alzheimer disease and mild cognitive impairment. We developed a 2-step algorithm using a convolutional neural network to perform brain parcellation followed by 3 classifier techniques including XGBoost for disease prediction. All classification experiments were performed using 5-fold cross-validation. The diagnostic performance of the XGBoost method was compared with logistic regression and a linear Support Vector Machine by calculating their areas under the curve for differentiating Alzheimer disease from mild cognitive impairment and mild cognitive impairment from healthy controls. RESULTS In a total of 4 datasets, 1099, 212, 711, and 705 eligible patients were included. Compared with the linear Support Vector Machine and logistic regression, XGBoost significantly improved the prediction of Alzheimer disease (P < .001). In terms of differentiating Alzheimer disease from mild cognitive impairment, the 3 algorithms resulted in areas under the curve of 0.758-0.825. XGBoost had a sensitivity of 68% and a specificity of 70%. In terms of differentiating mild cognitive impairment from the healthy control group, the 3 algorithms resulted in areas under the curve of 0.668-0.870. XGBoost had a sensitivity of 79% and a specificity of 80%. CONCLUSIONS The deep learning-based automatic brain segmentation and classification algorithm allowed an accurate diagnosis of Alzheimer disease using T1-weighted brain MR images. The widespread availability of T1-weighted brain MR imaging suggests that this algorithm is a promising and widely applicable method for predicting Alzheimer disease.

Abstract
Purpose: This work investigates the visual and anatomical outcomes of full-thickness macular hole (FTMH) repair surgery using air in comparison to gas tamponade. Methods: A retrospective consecutive review of medical records was undertaken of all patients undergoing pars plana vitrectomy for idiopathic FTMH at an academic practice from January 2010 to May 2017. Each operative report was reviewed to investigate the agent used for tamponade at the end of the surgery. Preoperative hole duration and size as measured using optical coherence tomography as well as successful postoperative hole closure were recorded. Use of gas or air was not randomized and was instilled at surgeon discretion. Results: The final analysis included 211 eyes. Gas was used as the tamponade agent in 171 of the 211 eyes; most of these eyes (144 of 171) received sulfur hexafluoride (SF6) and the remainder received perfluoropropane (C3F8). Forty eyes underwent only a complete fluid-air exchange without any gas placement following vitrectomy. There was no statistically significant difference between the 2 groups in mean preoperative macular hole size ( P = .43). Nine of the 171 macular holes receiving gas tamponade failed to close (5.3%). One of the 40 macular holes receiving only air failed to close (2.5%). There was no statistically significant difference in hole closure rates between the 2 groups ( P = .45). Conclusions: Air served as an equally efficacious internal tamponade agent in comparison to nonexpansile gas following idiopathic FTMH repair surgery.

Abstract
OBJECTIVES Uremic pruritus is common in patients with chronic kidney disease (CKD). The retention of uremic solutes is thought to be associated with uremic pruritus. Meanwhile, activation of protease-activated receptor-2 (PAR-2) has been suggested to play an important role in pruritus. The present study was performed to investigate the effects of uremic solutes on the expression of PAR-2 in the skin. METHODS Indoxyl sulfate (IS), p-cresol (PC), and uremic sera from CKD patients were used to stimulate PAR-2 expression in normal human epidermal keratinocytes (NHEKs). Also, NHEKs were additionally pretreated with soybean trypsin inhibitor to evaluate its inhibitory effect on PAR-2 expression. Patterns of cutaneous PAR-2 expression were investigated in skin samples from five CKD patients and CKD mice. RESULTS In NHEKs, IS, PC, and sera from CKD patients significantly induced PAR-2 mRNA and protein expression. Soybean trypsin inhibitor significantly decreased PAR-2 mRNA and protein expression in NHEKs treated with IS, PC, and CKD sera. NHEKs treated with IS and PC exhibited significant increases in protease activity. Skin from both CKD patients and mice exhibited marked upregulation of PAR-2 expression compared to control skin. CONCLUSIONS Results from the present study suggest that uremic solutes either directly or indirectly affect PAR-2 expression in the skin of CKD subjects, potentially playing an important role in the pathogenesis of uremic pruritus.
