The author states that it is not far until the state can regulate the global business with existing intellectual property laws. The author also mentions that laws related to intellectual property can tilt the scales of justice in intellectual commerce.

Rationale and Objective: A single-shot T2-weighted deep-learning-based image reconstruction (DL-HASTE) has been recently developed allowing for shorter acquisition time than conventional half-Fourier acquisition single-shot turbo-spin echo (HASTE). The purpose of this study was to compare image quality of conventional 6 mm HASTE with DL-HASTE at 4 mm and 6 mm slice thickness., Materials and Methods: 91 patients (51 female; mean±SD age: 44±10years) who underwent 3T MR enterography from 5/15/2023-7/15/2023 including pelvic conventional HASTE and DL-HASTE were included. Patients either had 4 mm-DL-HASTE or 6 mm-DL-HASTE. Four abdominal radiologists, blinded to sequence type, independently evaluated overall image quality, artifacts over bowel, bowel wall sharpness, and confidence for the presence/absence of bowel abnormalities on 5-point Likert scales. Readers recorded the presence/absence of ileal wall thickening, ileal inflammation, stricture, and penetrating disease on each sequence. Wilcoxon signed-rank test with continuity correction was used for paired comparisons and Wilcoxon rank sum test was used for unpaired ordinal comparisons. A p < .05 indicated statistical significance., Results: Acquisition times for 6 mm HASTE, 4 mm-DL-HASTE, and 6 mm-DL-HASTE were 64 s, 51 s, and 49 s, respectively. Overall image quality and bowel sharpness were significantly improved for 4 mm-DL-HASTE versus HASTE for 3/4 readers (all p < .05) and similar for the 4th reader (p > .05). Diagnostic confidence was similar for all readers (p > .05). 6 mm-DL-HASTE was similar to HASTE for bowel sharpness, image quality, and confidence for 3/4 readers (all p > .05). The presence of ileal thickening, ileal inflammation, stricture, and penetrating disease were similar for all readers for HASTE, 4 mm-DL-HASTE, and 6 mm-DL-HASTE (all p > .05)., Conclusion: 4 mm-DL-HASTE had superior image quality than conventional HASTE at shorter acquisition time., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Mahesh Keerthivasan reports a relationship with Siemens Healthineers AG that includes: employment.

Background: Minimally invasive focal therapy of low- to intermediate-risk prostate cancer is becoming more common and has demonstrated lower morbidity compared to other treatments. Multiparametric prostate magnetic resonance imaging (mpMRI) has the potential to be an effective posttreatment evaluation method for residual/recurrent neoplasm., Objective: This study aimed to evaluate the ability of mpMRI to detect residual/recurrent neoplasm after focal therapy treatment of prostate cancer using a 3-point Likert scale., Methods: This retrospective study included patients who underwent focal therapy utilizing cryoablation, high-frequency ultrasound, and radiofrequency ablation for low- to intermediate-risk prostate cancer with baseline mpMRI and biopsy and a 6- to 12-month follow-up mpMRI and biopsy. Three abdominal fellowship-trained readers were asked to evaluate the follow-up mpMRI utilizing a 3-point Likert scale based on the level of suspicion as "nonviable," "equivocal," or "viable." Diagnostic statistics and Light's κ for interreader variability were calculated., Results: A total of 142 patients were included (mean age, 65 ± 7 years). When considering "equivocal" or "viable" as positive, the overall sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the receiver operating characteristic curve (AUC) for detecting recurrent grade group (GG) 2 or greater disease for Reader 1 were 0.47, 0.83, 0.24, 0.93, and 0.65; for Reader 2, 0.73, 0.75, 0.26, 0.96, and 0.74; and for Reader 3, 0.73, 0.57, 0.17, 0.95, and 0.65. When considering "viable" as positive, the overall sensitivity, specificity, PPV, NPV, and AUC for Reader 1 were 0.47, 0.92, 0.41, 0.94, and 0.69; for Reader 2, 0.33, 0.97, 0.56, 0.93, and 0.65; and for Reader 3, 0.53, 0.84, 0.29, 0.94, and 0.69. κ was 0.39., Conclusions: This study suggests that DCE and DWI are the most important sequences in mpMRI and demonstrates the efficacy of utilizing a 3-point grading system in detecting and diagnosing prostate cancer after focal therapy., Clinical Impact: mpMRI can be used to monitor for residual/recurrent disease after focal therapy., Competing Interests: Samir S.

Background: Postacute Covid-19 patients commonly present with respiratory symptoms; however, a noninvasive imaging method for quantitative characterization of respiratory patterns is lacking., Purpose: To evaluate if quantitative characterization of respiratory pattern on free-breathing higher temporal resolution MRI stratifies patients by cardiopulmonary symptom burden., Study Type: Prospective analysis of retrospectively acquired data., Subjects: A total of 37 postacute Covid-19 patients (25 male; median [interquartile range (IQR)] age: 58 [42-64] years; median [IQR] days from acute infection: 335 [186-449])., Field Strength/sequence: 0.55 T/two-dimensional coronal true fast imaging with steady-state free precession (trueFISP) at higher temporal resolution., Assessment: Patients were stratified into three groups based on presence of no (N = 11), 1 (N = 14), or ≥2 (N = 14) cardiopulmonary symptoms, assessed using a standardized symptom inventory within 1 month of MRI. An automated lung postprocessing workflow segmented each lung in each trueFISP image (temporal resolution 0.2 seconds) and respiratory curves were generated. Quantitative parameters were derived including tidal lung area, rates of inspiration and expiration, lung area coefficient of variability (CV), and respiratory incoherence (departure from sinusoidal pattern) were. Pulmonary function tests were recorded if within 1 month of MRI. Qualitative assessment of respiratory pattern and lung opacity was performed by three independent readers with 6, 9, and 23 years of experience., Statistical Tests: Analysis of variance to assess differences in demographic, clinical, and quantitative MRI parameters among groups; univariable analysis and multinomial logistic regression modeling to determine features predictive of patient symptom status; Akaike information criterion to compare the quality of regression models; Cohen and Fleiss kappa (κ) to quantify inter-reader reliability. Two-sided 5% significance level was used., Results: Tidal area and lung area CV were significantly higher in patients with two or more symptoms than in those with one or no symptoms (area: 15.4 cm 2 vs. 12.9 cm 2 vs. 12.8 cm 2 ; CV: 0.072, 0.067, and 0.058). Respiratory incoherence was significantly higher in patients with two or more symptoms than in those with one or no symptoms (0.05 vs. 0.043 vs. 0.033). There were no significant differences in patient age (P = 0.19), sex (P = 0.88), lung opacity severity (P = 0.48), or pulmonary function tests (P = 0.35-0.97) among groups. Qualitative reader assessment did not distinguish between groups and showed slight inter-reader agreement (κ = 0.05-0.11)., Data Conclusion: Quantitative respiratory pattern measures derived from dynamic higher-temporal resolution MRI have potential to stratify patients by symptom burden in a postacute Covid-19 cohort., Level of Evidence: 3 TECHNICAL EFFICACY: Stage 3., (© 2024 The Authors.

Purpose: We present the surgical technique of localised excision of tarsal epithelium and replacement with oral mucous membrane tarsal patch grafting (MMTPG), to highlight novel indications of this technique for tarsal surface abnormalities beyond the lid margin., Methods: Retrospective case series of patients who underwent MMTPG for refractory tarsal conjunctival disease in three centers, with outcome measures of corneal epitheliopathy, visual acuity (VA), and symptomatic improvement., Results: 8 eyes of 8 patients were included, with surgical indications of medically recalcitrant Vernal Keratoconjunctivitis (VKC) (1), Giant Papillary Conjunctivitis (GPC) (1), or tarsal scarring in the setting of Ocular Cicatricial Pemphigoid (OCP) (2), Stevens-Johnson Syndrome (SJS) (2), advanced Meibomian Gland Dysfunction (MGD) (1) and Ligneous Conjunctivitis (LC) (1). Following MMTPG there were no recurrences of corneal epithelial defects or local tarsal conjunctival pathologies during the follow-up period (mean 28 months). Five eyes demonstrated an improvement in visual acuity of ≥2 Snellen chart lines. Symptomatic improvement was noted in all 8 eyes, and medication requirement was reduced., Conclusion: This report provides a novel conceptual insight to the successful use of MMTPG, highlighting its use in a range of conditions in therapeutically resistant cases.

Purpose: Retrospectively compare image quality, radiologist diagnostic confidence, and time for images to reach PACS for contrast enhanced abdominopelvic CT examinations created on the scanner console by technologists versus those generated automatically by thin-client artificial intelligence (AI) mechanisms., Methods: A retrospective PACS search identified adults who underwent an emergency department contrast-enhanced abdominopelvic CT in 07/2022 (Console Cohort) and 07/2023 (Server Cohort). Coronal and sagittal multiplanar reformatted images (MPR) were created by AI software in the Server cohort. Time to completion of MPR images was compared using 2-sample t-tests for all patients in both cohorts. Two radiologists qualitatively assessed image quality and diagnostic confidence on 5-point Likert scales for 50 consecutive examinations from each cohort. Additionally, they assessed for acute abdominopelvic findings. Continuous variables and qualitative scores were compared with the Mann-Whitney U test. A p < .05 indicated statistical significance., Results: Mean[SD] time to exam completion in PACS was 8.7[11.1] minutes in the Console cohort (n = 728) and 4.6[6.6] minutes in the Server cohort (n = 892), p < .001. 50 examinations in the Console Cohort (28 women 22 men, 51[19] years) and Server cohort (27 women 23 men, 57[19] years) were included for radiologist review. Age, sex, CTDlvol, and DLP were not statistically different between the cohorts (all p > .05). There was no significant difference in image quality or diagnostic confidence for either reader when comparing the Console and Server cohorts (all p > .05)., Conclusion: Examinations utilizing AI generated MPRs on a thin-client architecture were completed approximately 50% faster than those utilizing reconstructions generated at the console with no statistical difference in diagnostic confidence or image quality., (© 2024.

The aim of this study was to compare sequelae and acute kidney injury (AKI) occurrence among patients with necrotizing enterocolitis (NEC) after changing institutional guidelines replacing vancomycin with ampicillin for gram-positive coverage. This was a retrospective, single-center cohort analysis of patients from 2016-2020 (n = 73) with NEC at a surgical neonatal intensive care unit with a high community prevalence of methicillin-resistant Staphylococcus aureus (MRSA). Multivariate logistic regression was utilized to assess associations. Twenty-five (34%) patients had at least 1 sequela related to NEC. Ampicillin containing regimens were not associated with any sequelae type or AKI. Postmenstrual age < 29 weeks at diagnosis ([OR] 5.8 [1.2-28.8], P = .03; and receipt of vasopressors [OR] 3.3 [1.1-10.2], P = .04) were independently associated with sequalae. Stage III NEC was independently associated with AKI, OR 10.6 (2-55.6), P = .005. In conclusion, ampicillin-containing regimens are effective for NEC management at our institution despite a high prevalence of MRSA., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: To describe the clinical features, management, and long-term outcome of Infectious crystalline keratopathy (ICK)., Methods: The medical records of clinically diagnosed and microbiologically proven cases of ICK were reviewed from January 2011 to December 2022. Clinical characteristics include the presence of whitish needle-like projections with branching, limited to anterior-mid stroma. Keratoplasty being the most common risk factor, graft-related microbial keratitis during the same period was also studied. The demography, clinical profile, microbiology, treatment, and outcome were analyzed, and compared with secondary graft infiltrate(GI)., Results: Medical records of 24 cases with ICK were reviewed. The mean age was 49.3 ± 20.1 years, with 15(62.5%) males. Prior keratoplasty was done in 18 (75%) cases, with a mean graft size of 10.1 ± 1.5 mm, and mean interval between the last graft and presentation was 9.7 ± 6.2 (3-90) months. In comparison to GI (n = 24), ICK patients (n = 18,75%) were less symptomatic, presented late (7.3 ± 6.5 days vs 16.3 ± 19.4, p = 0.003), using frequent topical steroids (> 3 times/day, p =  0.006), smaller infiltrate size < 4 mm (p =  0.008), central (p =  0.02), less associated with epithelial defect (p =  0.0001), hypopyon (p =  of 0.0002), corneal perforation (p =  0.0006), and surgical management (p =  0.03). On microbiology, 22 (91.6%) ICK cases were culture positive, 14 (63.6%) gram-positive, 3 (13.6%) gram-negative, 2 (9%) mixed bacteria, and 3 (13.6%) fungus, comparable with GI., Conclusion: ICK affects poor ocular surfaces usually following keratoplasty with larger graft size, the use of steroids being the most common association, and it responds to medical management as compared to GI., (© 2024.

Objective: To describe the clinical profile of patients presented with Acanthamoeba keratitis (AK) to a multi-tier ophthalmology hospital network in India., Methods: This cross-sectional hospital-based study included 1945339 new patients registering between September 2016 and May 2022. Patients with clinically confirmed diagnosis of AK in one or both eyes were included in the study. All the relevant data were documented using an electronic medical record (EMR) system., Results: A total of 245 (0.013%) patients were diagnosed with AK and majority were male (62.86%) with unilateral (99.59%) affliction. The most common age group was during the fourth decade of life, 65 (26.53%) patients and predominantly were adults (95.51%). The prevalence of the infection was higher in patients from a lower socioeconomic status (43.27%) from rural geography (52.24%) and in agriculture-related work (28.16%). The most common inciting factor was injury with vegetative matter (8.98%), dust (7.76%) and contact lens wear (4.49%). The majority of the eyes had blindness (20/400 to 20/1200) in 116 (47.15%) eyes with a presenting visual acuity (logMAR) of 2.14 ± 1.04. Among the surgical interventions, therapeutic keratoplasty was performed in 41 (16.67%) eyes, penetrating keratoplasty in 22 (8.94%) eyes, and evisceration in 2 (0.81%) eyes., Conclusion: AK more commonly affects males presenting during the fourth decade of life from lower socio-economic status and is predominantly unilateral. A fourth of the affected eyes underwent keratoplasty and the majority had significant visual impairment at presentation.

Purpose: Neutrophils are known mediators of innate immunity, yet their effector function in herpesvirus infections remains poorly understood. Here, we elucidate the mechanistic action and pivotal role of neutrophil extracellular traps (NETs) during herpes simplex virus type 1 (HSV-1) ocular infection., Methods: Neutrophils were collected from mice for HSV-1 infection, fluorescence imaging, and immunoblotting assay. Tear samples from healthy subjects and patients with HSV-1 and mice were collected at L. V. Prasad Eye Institute, India, and at the University of Illinois, USA, respectively. For the in vivo study, C57BL/6 mice as well as diversity outbred mice were infected with HSV-1 (McKrae strain) followed by tear fluid collection at various time points (0-10 days). Samples were used for Flow cytometry, ELISA, and immunofluorescence assay. Human transcriptomic profile of keratitis dataset was used evaluate NETosis signaling pathways. We also performed neutrophil depletion studies., Results: Our data revealed a discernible temporal NET formation (NETosis) predominantly in the infected eye, across normal and diversity outbred murine models and human cases of HSV-1 infection. HSV-1 instigates swift NETosis governed by caspase-1 activation and myeloperoxidase secretion. Distinct accumulations of neutrophils, remaining unengaged in NET release in the contralateral eye post-infection, hinting at a proactive defensive posture in the uninfected eye. Moreover, neutrophil depletion accentuated ocular pathology, augmented viral load, and escalated disease scores, substantiating the protective effects of NETs in curtailing viral replication., Conclusions: Our report uncovers a previously unexplored mechanism of NETosis through pro-inflammatory cell death in response to ocular HSV-1 infection, and HPSE up-regulation, identifying new avenues for future studies.

Aim: To investigate the challenges and barriers in Danish care professionals' work in relation to elderly citizens who use substances. Method: The study draws on data from a "going along" study of care professionals' encounters with citizens as well as interviews with professionals. This was conducted in two smaller, rural municipalities in Denmark. Findings: Providing adequate care for elderly citizens who use substances can be highly challenging. This is due to a multitude of factors, especially (1) the complexity of their health conditions, (2) contradictory logics of care (autonomy vs. healthy living), (3) citizens often unpredictable behaviours, (4) lack of cooperation between welfare systems and, not least, (5) lack of knowledge and education among healthcare professionals. Conclusions: There is a need for more specialised procedures locally, the appointment of local "experts", better cooperation between sectors and easier accessible training and information on the group on a national level., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

A 3-year-old boy presented with repeated episodes of corneal erosions and ulceration and absence of tear secretion since birth. Examination under anesthesia revealed a dry ocular surface, with corneal scarring and vascularization. Computed tomography of the orbit showed complete absence of lacrimal glands bilaterally. Minor salivary gland transplantation was performed in the right eye, which was more severely affected. This procedure has been used to manage severe dry eyes but not previously for congenital alacrimia. On long-term follow-up, 5 years after surgery, we observed considerable improvement in the photophobia, corneal transparency, and neovascularization., (Copyright © 2024 American Association for Pediatric Ophthalmology and Strabismus.

In this article, we examine a group of older marginalized substance-using citizens and their relations to Danish health care. We offer empirical examples collected through ethnographic fieldwork, about how they handle their health situation and encounters with the Danish healthcare system. Analytically, we particularly draw on the concept of disposable ties, and suggest the term "brittle ties" to nuance the term and examine how perceived individual autonomy is weighted against health care trajectories and how these citizens often prefer to fend for themselves or lean on provisional networks rather than enter into health care trajectories and follow-up treatment.

We report the case of a female patient in her late 20s who visited the clinic with concerns about poor vision, redness, watering and a burning sensation in her left eye 2 weeks after undergoing a small incision lenticule extraction. She had no history of systemic illness or immunosuppressed status. On slit lamp examination, she was found to have corneal stromal infiltrates in the interface at multiple locations. Given the clinical diagnosis of microbial keratitis, corneal scraping of the interface infiltrate was performed and sent for microbiological examination revealing gram-positive, thin, beaded filaments that were acid-fast positive and later identified by growth in culture media as Nocardia species. This case was managed successfully with the use of topical amikacin and systemic trimethoprim-sulfamethoxazole with complete resolution of infection., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Purpose: Pseudomonas aeruginosa-induced keratitis is one of the most severe and challenging forms of corneal infection, owing to its associated intense inflammatory reactions leading to corneal necrosis and dense corneal scar with loss of vision. Since mesenchymal stem cells (MSCs) are reported to possess antimicrobial and immunomodulatory properties, they can be tested as an adjuvant treatment along with the antibiotics which are the current standard of care. This study aims to investigate the anti-bacterial and immunomodulatory roles of human bone marrow MSC-derived conditioned medium (MSC-CM) in P. aeruginosa-infected human corneal epithelial cells (HCECs) in vitro., Methods: The effect of MSC-CM on the growth of clinical isolates of P. aeruginosa was evaluated by colony-forming unit assay. The expression of inflammatory cytokines (IL-6 and TNF-α) and an antimicrobial peptide (Lipocalin 2) in lipopolysaccharide-treated MSCs and HCECs was analyzed through ELISA. Corneal epithelial repair following infection with P. aeruginosa was studied through scratch assay., Results: Compared to control (P. aeruginosa (5*10 5 ) incubated in DMEM (1 ml) at 37 °C for 16 h), MSC-CM significantly: i) inhibits the growth of P. aeruginosa (159*10 9 vs. 104*10 9  CFU/ml), ii) accelerates corneal epithelial repair following infection with P. aeruginosa (9% vs. 24% closure of the wounded area after 12 h of infection), and iii) downregulates the lipopolysaccharide-induced expression of IL-6, TNF-α and Lipocalin 2 in HCECs. A combination of MSC-CM with an antibiotic, Ciprofloxacin moderately regulated the expression of IL-6, TNF-α, and Lipocalin 2., Conclusion: MSC-CM holds promise as an adjunctive therapeutic approach for P. aeruginosa-induced corneal epithelial damage., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interest., (Copyright © 2024 Elsevier Ltd.

Purpose: Heparanase (HPSE) cleaves heparan sulfate proteoglycans during herpes simplex virus-1 (HSV-1) infection, aiding in viral egress and disease progression. Its action has been well established in in vitro and in vivo models, but its relevance in human patients remains unclear. This study aimed to specifically evaluate tear HPSE levels of patients with herpes simplex keratitis (HSK) and to correlate these findings with a commonly used murine model., Methods: Tear samples from patient and mice samples were collected at LV Prasad Eye Institute, Hyderabad, India, and at the University of Illinois, Chicago, IL, respectively. Tears were collected from HSV-1 patients, bacterial/fungal keratitis cases, and healthy individuals. For in vivo study, C57BL/6 mice were infected with HSV-1 (McKrae strain) followed by tear fluid collection at various time points (0-10 days)., Results: The HSV-1, bacterial keratitis, fungal keratitis, and healthy control groups each had 30 patients. There was a significant difference in HPSE expression in the HSV-1 infected eyes (1.55 ± 0.19 units/mL) compared to HSV-1 contralateral eyes (1.23 ± 0.13 units/mL; P = 0.82), bacterial keratitis eyes (0.87 ± 0.15 units/mL; P = 0.0078), fungal keratitis eyes (0.64 ± 0.09 units/mL; P < 0.00001), and normal controls (0.53 ± 0.06 units/mL; P < 0.00001). C57BL/6 mice tear HPSE expression in infected eyes was 0.66 to 5.57 ng heparan sulfate (HS) removed per minute when compared to non-infected eye (range, 0.70-3.67 ng HS removed per minute)., Conclusions: To the best of our knowledge, this study is the first to report elevated HPSE levels in the tears of patients with different forms of HSV-1 keratitis, and it confirms similar findings in a murine model, providing a valuable basis for future in vivo and clinical research on HSV-1 ocular infection.

Objective: To describe the demographics and clinical profile of Herpes Simplex Virus (HSV) Keratitis in patients presenting to a multi-tier ophthalmology hospital network in South India., Methods: We have reviewed the medical records of all patients having a clinical diagnosis of any form of HSV keratitis, seen between May 2012 and August 2020 across the L V Prasad Eye Institute network. All the further analyses of the groups were performed using the keywords used for making the diagnosis of HSV keratitis and the data were collected from the electronic medical record system., Results: There were a total of 8308 (N = 8897 eyes) patients. Male: female ratio was 5368 (64.61%):2940 (35.39%). Unilateral involvement was in 7719 (92.91%) patients. The most common age group affected was between the third to fifth decades of life with 1544 (18.58%). 3708 (1.68%) eyes had mild visual impairment (< 20/70) while the rest of them had moderate to severe visual impairment as observed mainly (p ≤ 0.01) in Necrotizing stromal keratitis. 7314 (82.21%) eyes had normal intraocular pressure (10-21 mm Hg) while raised most commonly in keratouveitis (P ≤ 0.01). Epithelial Keratitis, Immune Stromal Keratitis, Endotheliitis, Neurotrophic keratopathy and Keratouveitis were observed in 1875 (17.22%) eyes, 5430 (61.03%) eyes, in 129(1.45%) eyes, 1188 (13.35%) eyes, 148 (1.66%) eyes and 256 (2.88%) eyes respectively., Conclusion: Based on our institute-based data, the most common type of HSV keratitis is Immune stromal keratitis followed by epithelial keratitis. Although not representative of the general population, this data provide useful insights related to HSV keratitis from India., (© 2023.

Purpose: The aim of this study was to compare the efficacy of monotherapy (topical linezolid 0.2%) versus a combination of antibiotics (topical linezolid 0.2% and topical azithromycin 1%) for the treatment of Pythium insidiosum keratitis., Methods: Cases of P. insidiosum keratitis were prospectively randomized into group A on topical 0.2% linezolid along with topical placebo (sodium carboxymethyl cellulose [CMC] 0.5%) and group B on a combination of topical 0.2% linezolid and topical 1% azithromycin. Both groups were compared by proportion of both clinical resolution and worsening of keratitis along with the number of therapeutic penetrating keratoplasty (TPK) performed at 3 months., Results: We initially planned N = 66 patients but later limited to 20 (N = 10 in each group) patients owing to one interim analysis. The average size of the infiltrate in group A and B was 5.6 ± 1.5 mm and 4.8 ± 2.0 mm, respectively, with a mean Logarithm of the Minimum Angle of Resolution (logMAR) visual acuity of 2.74 ± 0.55 and 1.79 ± 1.19. At 3 months, from group A, 7 (70%) patients needed TPK and 2 patients had signs of resolution, whereas from group B, 6 (60%) patients achieved complete resolution ( P = 0.0003) and 2 were improving while only 1 needed TPK ( P = 0.02). The median duration of treatment in group A and B, with the study drugs, was 31 days (17.8-47.8) and 101.5 days (80-123.3), P value = 0.003, respectively. Final visual acuity at 3 months was 2.50 ± 0.81 and 0.75 ± 0.87, P = 0.02, respectively., Conclusions: A combination of topical linezolid and topical azithromycin was found to have superior efficacy than the monotherapy with topical linezolid for the management of Pythium keratitis., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Demand for prostate MRI is increasing, but scan times remain long even in abbreviated biparametric MRIs (bpMRI). Deep learning can be leveraged to accelerate T2-weighted imaging (T2WI)., Purpose: To compare conventional bpMRIs (CL-bpMRI) with bpMRIs including a deep learning-accelerated T2WI (DL-bpMRI) in diagnosing prostate cancer., Study Type: Retrospective., Population: Eighty consecutive men, mean age 66 years (47-84) with suspected prostate cancer or prostate cancer on active surveillance who had a prostate MRI from December 28, 2020 to April 28, 2021 were included. Follow-up included prostate biopsy or stability of prostate-specific antigen (PSA) for 1 year., Field Strength and Sequences: A 3 T MRI. Conventional axial and coronal T2 turbo spin echo (CL-T2), 3-fold deep learning-accelerated axial and coronal T2-weighted sequence (DL-T2), diffusion weighted imaging (DWI) with b = 50 sec/mm 2 , 1000 sec/mm 2 , calculated b = 1500 sec/mm 2 ., Assessment: CL-bpMRI and DL-bpMRI including the same conventional diffusion-weighted imaging (DWI) were presented to three radiologists (blinded to acquisition method) and to a deep learning computer-assisted detection algorithm (DL-CAD). The readers evaluated image quality using a 4-point Likert scale (1 = nondiagnostic, 4 = excellent) and graded lesions using Prostate Imaging Reporting and Data System (PI-RADS) v2.1. DL-CAD identified and assigned lesions of PI-RADS 3 or greater., Statistical Tests: Quality metrics were compared using Wilcoxon signed rank test, and area under the receiver operating characteristic curve (AUC) were compared using Delong's test., Significance: P = 0.05., Results: Eighty men were included (age: 66 ± 9 years; 17/80 clinically significant prostate cancer).

Purpose: Fusarium keratitis possesses significant diagnostic and therapeutic challenges. Medically relevant Fusaria belong to various species complexes and show prominent differences in their antifungal susceptibility profile which may influence the clinical outcome. Rapid diagnostic methods are warranted for precise identification of species complexes for prompt initiation of correct antifungals. The aim of the study was to compare between matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) and polymerase chain reaction sequencing for correct species-level identification and to analyze the clinical outcome among different Fusarium species complexes., Methods: Twenty-nine culture-proven Fusarium keratitis cases were included in this study. A phylogenetic tree was constructed after TEF1α gene sequencing and isolates were subjected to MALDI-TOF MS, followed by database expansion and identification. Clinical outcome and risk association among species complexes were analyzed retrospectively., Results: Maximum likelihood phylogeny categorized 68.9% isolates as Fusarium solani species complex (FSSC), 17.2% as Fusarium dimerum species complex (FDSC), followed by 13.7% as Fusarium fujikuroi species complex (FFSC). With extended database, MALDI-TOF MS could correctly speciate 96.5% (28/29) isolates. Previous antibiotic usage ( P = 0.034) and preoperative antifungal treatment with natamycin, voriconazole, or ketoconazole ( P = 0.025) were significantly higher in the FSSC group. The patients in the FFSC group had a significantly longer duration of symptoms at the time of clinical presentation to the clinic (15 days vs. 5 days, P = 0.030). Among 11 patients with a clinically poor outcome, 9 (31%) had FSSC infection., Conclusions: Patients infected with the FSSC had more aggressive infection with poor prognosis. MALDI-TOF MS can serve as the best alternative method to conventional molecular identification with reduced turnaround time, which may help the ophthalmologists to consider the appropriate antifungals or early surgical intervention for improved outcome., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Monoclonal antibody (palivizumab), intravenous immune globulin (IGIV), or respiratory syncytial virus (RSV)-polyclonal-hyperimmune-globulin (RSV-IG as Respigam®, RI-001, RI-002) are used with ribavirin in RSV-infected immunocompromised patients, with debated efficacy. Palivizumab-resistance (PR) can arise during treatment of persistent infections in this population. RSV-IG may confer benefit in PR-RSV infection., Methods: RSV-IG [RI-001] was provided for an immunocompromised infant with RSV-pneumonitis refractory to ribavirin and palivizumab. RSV-neutralizing antibody, respiratory RSV load (qPCR), and F-gene-sequence-detection of PR was determined. Prophylactic RSV-IG [RI-002] or palivizumab was administered in a cotton-rat model infected with wild-type and PR-RSV. Lung RSV load and neutralizing antibody were measured., Results: As protective RI-001-neutralizing antibody titers waned in the infant, a subpopulation of PR-escape mutants were detected with a fatal RSV-burden in the lungs. In PR-RSV-infected cotton rats, prophylactic RI-002 reduced RSV-load in the lungs (2.45 vs 0.28 log 10  PFU/g lung-tissue reduction, respectively, p < 0.05) and provided protective RSV-neutralizing antibody., Conclusions: RSV-IG and ribavirin use in immunocompromised patients requires further study., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Malignant transformation in leiomyoma is rare, with a few documented cases of sarcomatous transformation in leiomyomas. However, carcinosarcomatous transformation in leiomyomas is extremely infrequent. A 45-year-old female presented with a mass sensation per abdomen for the last five months. An abdominal ultrasound revealed multiple uterine fibroids. Contrast-enhanced magnetic resonance imaging revealed a large multiloculated abdominopelvic mass arising from the fundus of the uterus, along with multiple smaller subserosal fibroids. A total abdominal hysterectomy with bilateral salpingectomy was performed. Grossly, the uterus was bosselated with multiple subserosal fibroids. The larger degenerated fibroid showed a smooth outer surface; however, the cut surface was predominantly cystic and filled with necrotic material. Microscopically and immunohistochemically, the larger mass showed a high-grade biphasic tumor comprising carcinomatous and sarcomatous components with the peripheral solid areas showing compressed smooth muscle bundles representing the residual leiomyomatous areas. A final diagnosis of carcinosarcomatous transformation in leiomyoma was rendered. The index report highlights the significance of systematic gross and microscopic examination of all the uterine masses in patients with multiple leiomyomata.

Purpose: The aims of this study were to assess the trends in microorganisms from patients with infectious keratitis and to assess their antibiogram patterns at a tertiary eye care center in India., Methods: In this retrospective observational case series, microbiological records of all corneal ulcers were reviewed from 1991 to 2020 and assessed for trends in keratitis and antibiotic susceptibility using the χ 2 test., Results: Of the total of 51,747 patients, 51.13% were culture positive. A decrease in bacteria was noted from 56% to 38%, with a parallel increase in fungal isolates from 24% to 51%. Gram-positive bacteria accounted for 70.8% of the total bacteria, a trend in rise of Streptococcus pneumoniae (31%) and a decreasing trend in prevalence of Staphylococcus epidermidis was observed over 30 years . Pseudomonas aeruginosa (55.5%) was the most prevalent gram-negative pathogen, whereas Fusarium spp . (33.1%) and Aspergillus spp. (32.4%) were the most common fungal isolates. The susceptibility of gram-positive organisms to cefazolin decreased from 95.5% to 66% ( P = 0.0001), amikacin from 88% to 55% ( P = 0.0001), and vancomycin from 98.9% to 90.7% ( P < 0.05). A similar decrease in susceptibility was also significant for gram-negative organisms with piperacillin/tazobactam and chloramphenicol ( P < 0.05). A significant trend toward increasing resistance against fluoroquinolones was also observed for ciprofloxacin (gram-positive organisms: 16% to 50%; gram-negative organisms: 11.5% to 18.7%), gatifloxacin (38% to 47%), and moxifloxacin (9.4% to 29%)., Conclusions: The spectrum of keratitis has changed, and fungus is now the predominant etiology. An increasing trend in resistance to all antibiotics studied would affect the empiric treatment, also suggesting regular surveillance., Competing Interests: Conflicts of interest statement: The authors have no conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: To study the challenges of managing microbial keratitis(MK) during the COVID19 pandemic related lockdown and assess the outcomes of treatment at a tertiary cornea service., Methods: Retrospective, non comparative study of electronic medical records of MK presenting to a network of four tertiary care cornea services. The medical history, presenting clinical features, microbiology work up and treatment outcomes were analyzed. The primary outcome measure was final outcome at last follow up. Secondary outcomes measures were non-compliance to treatment due to travel restrictions, therapeutic PKP not done due non availability of corneal tissues. Results- MK was noted in 330 eyes of 330 patients between April and May 2020. Of these 237(71.8%) were males. Median age was 45 years(IQR, 33-56). Low socioeconomic status noted in 102(30.9%). Patients travelling beyond the district from where the hospital was located comprised of 64.9%(n=214). At a median follow up of 32 days(IQR, 9-54), 118(35.8%) patients had resolved, with medical management, 73(22.1%) patients were under active treatment, 139(42.1%) were lost to follow up. Sixty-six patients(20%) were non-compliant to treatment of which 59 could not follow appointment schedule due to travel restrictions. Therapeutic PKP (TPK) was planned in 48/128 (37.5%) patients, but was performed in only 34/48 (70.8%) due to non-availability of donor corneas., Conclusions: Abnormal social circumstances due to the COVID pandemic and the ensuing impediments to travel for access to health care affected compliance to treatment of ocular emergencies such as microbial keratitis., (© 2022.

Purpose: To describe the clinical outcomes of therapeutic penetrating keratoplasty (TPK) in patients with Pythium insidiosum keratitis following treatment with anti-pythium therapy (APT) consisting of linezolid and azithromycin., Methods: A retrospective review of medical records from May 2016 to December 2019 of patients with P. insidiosum keratitis was carried out. Patients who were treated with APT for a minimum of 2 weeks and then subsequently underwent TPK were included in the study. Data on demographic characteristics, clinical features, microbiology characteristics, and intraoperative details, postoperative outcomes were documented., Results: A total of 238 cases of Pythium keratitis were seen during the study period and 50 cases that satisfied the inclusion criteria were included. The median of the geometric mean of the infiltrate was 5.6 mm (IQR 4.0-7.2 mm). The patients received topical APT for a median of 35 days (IQR 25-56) prior to surgery. The most common indication of TPK was worsening keratitis (41/50, 82%). No recurrence of infection was observed. An anatomically stable globe was noted in 49/50 eyes (98%). The median graft survival rate was 2.4 months. A clear graft was present in 10 eyes (20%) with a final median visual acuity of 20/125 after a median follow-up period of 18.4 months (IQR 11-26 months). Graft size of less than 10 mm [OR: 5.824 (CI:1.292-41.6), P = 0.02] was found to be significantly associated with a clear graft., Conclusion: Performing TPK following the administration of APT has good anatomical outcomes. A smaller graft of <10 mm was associated with a higher chance of graft survival., Competing Interests: None

Purpose: To describe clinico-microbiological features and outcomes of Serratia keratitis and to compare them with Pseudomonas aeruginosa keratitis., Methods: Cases of microbiologically proven Serratia keratitis and P. aeruginosa keratitis were reviewed. Data regarding demographic and clinical characteristics, and outcomes were recorded., Results: 39 patients with pure Serratia keratitis were included. Median presenting vision was 1.8 logMAR (IQR, 0.8-2.4) and median infiltrate size was 5 mm (IQR 3-7.8 mm). An ocular risk factor was present in 35 (89.7%) cases. S. marcescens was the most common species (31/39, 79.5%). Medical resolution was observed in 36/39 (92.3%) cases, while three (7.7%) eyes needed penetrating keratoplasty. On comparing with P. aeruginosa keratitis (58 eyes), no difference in outcomes (p = .14) was noted., Conclusion: Serratia keratitis usually occurs in eyes with a compromised surface and has good resolution with medical therapy. Both Serratia and P. aeruginosa keratitis have similar outcomes.

Purpose: To demonstrate the suitability of using decellularized SMILE (Small-incision Lenticule Extraction) lenticules for culturing and transplanting the corneal endothelium (CE)., Methods: The SMILE lenticules, obtained during refractive surgery, were decellularized by incubating in CE culture medium and fetal bovine serum. Decellularization was confirmed by hematoxylin and eosin staining, DAPI staining, and gel electrophoresis. The amount of DNA per milligram of dry tissue weight was calculated to quantify the residual nuclear content. The transparency of the decellularized lenticules was determined by calculating the modulation transfer function. Immunostaining for stromal collagens and glycosaminoglycan was performed using specific antibodies. Engineered tissue was constructed by culturing the CE cells on lenticules and staining for ZO-1, Na/K ATPase, and N-cadherin. The functionality of the engineered tissues was assessed by transplanting them onto edematous human donor corneas and perfusing for 10 days ex-vivo ., Results: The residual DNA per milligram of dry tissue weight was found to be significantly reduced ( p  < 0.0001) in serum (0.255 µg/mg) and Opti-MEM (0.140 µg/mg) when compared to fresh lenticules (3.9 µg/mg). Decellularization did not alter the arrangement of the collagen fibers or the transparency of the lenticules. CE cells attached and matured to express ZO-1, Na/K ATPase, and N-cadherin at two weeks after seeding. The engineered tissue upon transplantation significantly reduced the corneal edema ( p  < 0.05) and the transplanted cells remained intact on the SMILE lenticule post-transplantation., Conclusion: This study demonstrates the suitability of using SMILE lenticules decellularized using a simple, chemical-free method for engineering the corneal endothelium for transplantation.

A man in late 40s presented with corneal ulcer of the right eye of 1 month duration. He had a central corneal epithelial defect measuring 4.6×4.2 mm with an underlying 3.6×3.5 mm anterior to mid stromal patchy infiltrate and 1.4 mm hypopyon. Gram stain of the colonies on chocolate agar showed presence of confluent thin branching, gram-positive beaded filaments, which were positive after 1% acid fast stain. This confirmed our organism to be Nocardia sp. Topical amikacin was started but continued worsening of the infiltrate and presence of a ball of exudates in the anterior chamber, prompted the use of systemic trimethoprim-sulfamethoxazole. There was a dramatic improvement in the signs and symptoms, with complete resolution of infection over a period of 1 month., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Background: Pythium insidiosum is an important cause of infectious keratitis from tropical and sub-tropical countries. Due to its closely mimicking clinical and microbiological features with fungus, it remained unidentified and managed as fungal keratitis for a long time. Previously all patients had poor outcomes with antifungal therapy and needed surgical treatment with higher rates of recurrences of infection leading to loss of an eye. Thus, a novel approach was required to treat it and, in this article, we would like to elaborate on the drastic change which these 5 years have brought in the management of this condition., Methods: In view of making a consolidated article comprising all the required information and also our clinical experience in the management of Pythium keratitis, we extensively reviewed several articles available on it over PubMed and Google scholars. Relevant literature describing details about Pythium , its clinical correlation, and recent advances from 52 articles including 12 articles from our group were finally included., Results: Our group identified and highlighted the unique clinical and microbiological features of Pythium insidiosum , performed several in-vitro, in-vivo studies along with clinical trials, and proposed the strategic way of its diagnosis and treatment. The use of antifungals was replaced with antibacterial medications and this resulted in better medical and surgical outcomes., Conclusion: The diagnosis and management of Pythium insidiosum is constantly evolving with several recent works pointing out the possible changes in the practice patterns for the management of this challenging form of keratitis.

A 96-year-old woman had a suboptimal evaluation of liver observations at abdominal MRI due to significant respiratory motion. State-of-the-art strategies to minimize respiratory motion during clinical abdominal MRI are discussed., (© RSNA, 2022.)

Pythium insidiosum is a parasitic oomycete that can cause keratitis and closely resembles fungus, both clinically and morphologically. It requires a trained microbiologist for its differentiation from fungal filaments and has poor response to antifungal therapy. We present a case of primary isolation of the organism from the vitreous cavity in a case of endophthalmitis. The infection spread quickly and involved all the ocular tissues. The eye had poor visual outcome despite a sequence of rapidly completed retinal and corneal surgeries along with initiation of anti-Pythium therapy.

Purpose: To describe the clinical picture and outcome of a case of Pythium keratitis, presenting as peripheral ulcerative keratitis (PUK)., Case Summary: A 54- year- old male presented to the clinic with a PUK in the right eye. Systemic investigations were performed to rule out associated collagen vascular disorders. Microbiological examination of corneal scrapings was performed to rule out secondary infection which revealed gram positive cocci on Gram stain. There was no growth of any organism on culture. Topical vancomycin 5% and ciprofloxacin 0.3% were started initially. On regular follow-up, there was worsening of clinical signs. Topical and oral corticosteroids were further added. Due to progressive worsening of infiltrate size and corneal perforation, therapeutic penetrating keratoplasty was performed. Pythium insidiosum (confirmed by DNA sequencing and zoospore formation) was grown from excised corneal button and the histopathology revealed filaments suggestive of Pythium species., Conclusion: This case describes the uncommon manifestation of Pythium insidiosum keratitis presenting as peripheral ulcerative keratitis.

Introduction: Acanthamoeba is an emerging pathogen, infamous for its resilience against antiprotozoal compounds, disinfectants and harsh environments. It is known to cause keratitis, a sight-threatening, painful and difficult to treat corneal infection which is often reported among contact lens wearers and patients with ocular trauma. Acanthamoeba comprises over 24 species and currently 23 genotypes (T1-T23) have been identified., Aims: This retrospective study was designed to examine the Acanthamoeba species and genotypes recovered from patients with Acanthamoeba keratitis (AK), determine the presence of endosymbionts in ocular isolates of Acanthamoeba and review the clinical presentations., Methodology: Thirteen culture-confirmed AK patients treated in a tertiary eye care facility in Hyderabad, India from February to October 2020 were included in this study. The clinical manifestations, medications and visual outcomes of all patients were obtained from medical records. The Acanthamoeba isolates were identified by sequencing the ribosomal nuclear subunit (rns) gene. Acanthamoeba isolates were assessed for the presence of bacterial or fungal endosymbionts using molecular assays, PCR and fluorescence in situ hybridization (FISH)., Results: The mean age of the patients was 33 years (SD ± 17.4; 95% CI 22.5 to 43.5 years). Six (46.2%) cases had AK associated risk factors; four patients had ocular trauma and two were contact lens wearers. A. culbertsoni (6/13, 46.2%) was the most common species, followed by A. polyphaga and A. triangularis. Most of the isolates (12/13) belonged to genotype T4 and one was a T12; three sub-clusters T4A, T4B, and T4F were identified within the T4 genotype. There was no significant association between Acanthamoeba types and clinical outcomes. Eight (61.5%) isolates harboured intracellular bacteria and one contained Malassezia restricta. The presence of intracellular microbes was associated with a higher proportion of stromal infiltrates (88.9%, 8/9), epithelial defect (55.6%, 5/9) and hypopyon (55.6%, 5/9) compared to 50% (2/4), 25% (1/4) and 25% (1/4) AK cases without intracellular microbes, respectively., Conclusions: Genotype T4 was the predominant isolate in southern India. This is the second report of T12 genotype identified from AK patient in India, which is rarely reported worldwide. The majority of the Acanthamoeba clinical isolates in this study harboured intracellular microbes, which may impact clinical characteristics of AK., (© 2022. The Author(s).)

No previous studies have investigated how political measures, opinions and views of people with dual diagnoses, organisational requirements and professional values are purposefully communicated, mediated and/or integrated in digital records in mental health care. It remains unclear how health records function as both clinical vehicles for documentation, audit and quality assurance in patient care as well as political vehicles of power to articulate and reproduce idealised relations among actors and their roles in mental health. Informed by Bacchi's 'What's the problem represented to be' (WPR) approach, we consider how problems of dually diagnosed persons with co-occurring mental health conditions and drug use (DDPs) are represented and how the tools required to fix the patients' problems are communicated and legitimised in 10 digital health records consisting of 3830 pages of data. In the discussion, we distinguish their multiple purposes by discussing how their structure is shaped by broader discourses in health care. Then, we consider how the structure of records delineates professionals' autonomy, discretionary action and service provision in ways that limit possibilities for including mental health patients' experiences and exclude service users' voices from care planning., (© 2022 The Authors.
