Visual acuity, intraocular pressure, presence of anterior chamber cells, and steroid usage were analyzed pre- and post-operatively. Patient eyes with a history of uveitis, autoimmune disease, complicated cataract surgery, combined surgery other than ECP, and less than 3 months of follow-up were excluded.Results: This study consisted of 4423 eyes from 2903 patients, meeting the inclusion criteria (phacoemulsification only group n=4242 and phacoemulsification/ECP group n=181 eyes). PAU developed in 14.9% in the phacoemulsification with ECP group compared to 1.7% who had phacoemulsification alone. White patients had a 17.9 (95% CI: 7.8– 41.1, p< 0.0001) increased odds of developing persistent anterior uveitis with a combined procedure compared to phacoemulsification only, while Non-white patients had a 5.8 (95% CI: 2.8– 12.1, p< 0.0001) increased odds. Despite the higher odds ratio in White patients, this group had a significantly lower rate of PAU compared to Non-white patients after phacoemulsification/ECP.Conclusion: The addition of endoscopic cyclophotocoagulation to phacoemulsification significantly increases the risk of developing PAU in the post-operative period compared to phacoemulsification alone.Keywords: minimally invasive glaucoma surgery, post-operative inflammation

All ophthalmic trauma cases were included and compared to non-traumatic ophthalmology malpractice cases.Results: Forty-four ophthalmic trauma cases were included. Of these cases, 90.9% of ophthalmic trauma plaintiffs were male compared to 54.8% of plaintiffs in ophthalmology as a whole (P=< 0.001); 34.1% of cases involved minor plaintiffs compared to 6.4% in ophthalmology as a whole (P=< 0.001). Cases involving minors were more likely to be resolved in favor of the plaintiff than cases involving adult plaintiffs (53.3% vs 37.9%); however, this was not found to statistically significant (P=0.35). Overall, 54.5% of cases were resolved in favor of defendants; 40.9% of cases were resolved via jury trial with 50.0% resulting in payments to plaintiffs compared to the 29.6% rate of plaintiff verdicts in ophthalmology as a whole. Open globe injuries represented 61.4% of cases; 55.6% of these cases had intraocular foreign bodies and 37.0% developed endophthalmitis. Most cases (63.6%) alleged insufficient intervention. Of these cases, 31.8% of cases involved surgical or procedural claims, and 4.5% involved medical claims only.Conclusion: Males and minors were overrepresented among plaintiffs in ocular trauma litigation. Most cases involved open globe injuries, often complicated by retained intraocular foreign bodies and endophthalmitis. Analysis of malpractice litigation in ophthalmic trauma calls attention to commonly litigated scenarios to improve clinical practice and to inform risk management.Keywords: malpractice, litigation, risk, trauma, intraocular foreign body, open globe, orbital fracture, endophthalmitis

Asima Bajwa,1 Travis Peck,1 Ashvini K Reddy,2 Peter A Netland,1 Yevgeniy Shildkrot1 1Department of Ophthalmology, University of Virginia, Charlottesville, VA, USA; 2Johns Hopkins Wilmer Eye Institute, Baltimore, MD, USA Purpose: To evaluate the long-term efficacy of the 0.70 mg dexamethasone (DEX) intravitreal implant in patients with birdshot chorioretinopathy (BSCR).Methods: Retrospective descriptive case series of BSCR patients treated with DEX implant (DEX implant 0.70 mg, DEX). Patients receiving treatment between September 2013 and November 2016 with a minimum follow-up (FU) of 12 months were included. The outcomes of primary interest were vision-related functioning, Snellen visual acuity, ocular inflammation status, presence or absence of vasculitis, change in central macular thickness, and development of glaucoma and/or cataract. Change in vision-related functioning was evaluated by comparing the National Eye Institute Visual Function Questionnaire-25. The outcomes were assessed at baseline, after DEX implant, at time of relapse, and at last FU.Results: Three patients (six eyes) were included in the study and were followed for 1–3 years. They received 1–4 DEX implants OU. All patients demonstrated improvement in National Eye Institute Visual Function Questionnaire-25 scores. Mean Snellen visual acuity better than or equal to 20/40 was seen in three eyes at baseline and five eyes at last FU. At induction, all of the patients (six eyes) had active vitritis and two (four eyes) had retinal vasculitis. All three patients (six eyes) were quiet at last FU. One patient (two eyes) developed bilateral ocular hypertension requiring topical therapy and discontinuation of DEX implants. Two patients (three eyes) developed posterior subcapsular cataract during therapy. Two patients (four eyes) showed progression of disease while on DEX therapy. All patients were eventually transitioned to systemic immunosuppressive drug therapy.Conclusion: BSCR patients receiving DEX implant experienced clinically meaningful improvements in patient-reported visual function as well as ocular inflammation. However, patients in this study required repeat implantation and were unable to be maintained on DEX implant long term due to development of adverse effects or progression of disease. Eventually, it was necessary to transition to systemic immunosuppressive therapy in all patients. Keywords: birdshot chorioretinopathy, dexamethasone implant, inflammation, uveitis

Rabia Aman,1 Stephanie B Engelhard,1 Asima Bajwa,1 James Patrie,2 Ashvini K Reddy1 1Department of Ophthalmology, 2Department of Public Health Sciences, University of Virginia, Charlottesville, VA, USA Purpose: To assess ocular hypertension (OHT) and hypotony as outcomes of uveitis in patients managed in a mid-Atlantic tertiary care center. Methods: Retrospective, observational study of uveitis patients seen at the University of Virginia from 1984 to 2014. Results: A total of 442 patients (582 eyes) with uveitis were identified and included in the study. The patient population was 57.0% female. Overall, 61.9% were Caucasian and 26.6% were African American. Mean age was 46.8 years. Overall, 11.5% of the eyes had OHT at initial visit, and 7.9% had OHT at final visit (P=0.035). For each additional decade of life, the odds that an eye had OHT were elevated by a factor of 1.15 (95% confidence interval [CI]: [1.02, 1.30], P=0.027) at initial visit and by a factor of 1.15 (95% CI: [1.00, 1.32], P=0.055) at final visit. The odds that an anterior uveitis eye had OHT were greater by a factor of 2.50 (95% CI: [1.22, 5.14], P=0.013) than the odds for a nonanterior uveitis eye at initial visit and greater by a factor of 2.61 (95% CI: [1.24, 5.50], P=0.011) at final visit. For each additional 0.5 logarithm of the minimum angle of resolution increase in initial visual acuity, the odds that an affected eye had OHT were elevated by a factor of 1.18 (95% CI: [1.00, 1.39], P=0.047) at initial visit and 1.23 (95% CI: [0.99, 1.54], P=0.065) at final visit. Overall, 21 of 582 eyes (3.6%) were hypotonous initially, while 24 of 582 eyes (4.1%) were hypotonous at final follow-up (P=0.631). Conclusion: OHT was associated with increasing age, anterior uveitis, and poor presenting visual acuity. Ocular hypotony was more common in anterior uveitis than in nonanterior uveitis. Fluctuations in intraocular pressure are an important cause of visual impairment in patients with uveitis. Careful monitoring of all uveitis patients, and especially those most at risk for fluctuations in intraocular pressure, can preserve vision and improve patient outcomes.

Stephanie B Engelhard,1 James Patrie,2 John Prenshaw,1 Asima Bajwa,1 Rose Monahan,1 Ashvini K Reddy1 1Department of Ophthalmology, 2Department of Public Health Sciences, University of Virginia, Charlottesville, VA, USA Purpose: The purpose of this study was to conduct an in-depth analysis of traumatic uveitis in patients managed in a mid-Atlantic tertiary care center with the goal of better characterizing the clinical features and outcomes of this large and important subset of uveitis patients.Methods: This was a retrospective, observational study comparing traumatic uveitis patients with nontraumatic uveitis patients seen at the University of Virginia, Charlottesville, VA, USA, from 1984 to 2014.Results: Fifty-four traumatic uveitis patients (55 eyes) were identified. The patient population was 70.4% male, 57.4% Caucasian, and 37.0% African American. Mean age at diagnosis was 31.2 years; mean duration of follow-up was 5.4 years; and mean number of visits to the clinic was 4. The most common treatment modality was local steroids (77.8%). Glaucoma was medically managed in eight patients (14.8%). Cataract surgery was performed in five patients (9.3%). Mean best-corrected visual acuity at baseline for traumatic uveitis patients was 0.33 logMAR (SD 0.42) at the initial visit and 0.16 logMAR (SD 0.33) at the final visit. Mean baseline intraocular pressure (IOP) in the traumatic uveitis group was 15.5 mmHg (SD 7.4) at the initial visit and 14.6 mmHg (SD 4.0) at the final visit. Patients in the traumatic uveitis cohort tended to have better visual outcomes than those in the nontraumatic uveitis cohort.Conclusion: In our series, traumatic uveitis patients tended to be young and male and present with unilateral disease, all findings consistent with other reports. Despite relatively good visual outcomes, the traumatic uveitis patients still experienced a high burden of disease, measured both in the number of clinic visits and duration of follow-up. Due to the young mean age of patients, these disease burdens and decreased quality of life are nontrivial, emphasizing the importance of careful management and prompt treatment of this subset of uveitis patients.

Asima Bajwa,1 Chang Sup Lee,1 Jim Patrie,2 Wenjun Xin,2 Ashvini K Reddy1 1Department of Ophthalmology, 2Department of Public Health Sciences, University of Virginia, Charlottesville, VA, USA Purpose: To report the clinical outcomes of uveitis patients at the University of Virginia. Methods: Retrospective, observational study of uveitis patients seen at the University of Virginia from 1984 to 2014. Parametric and nonparametric methods were used to analyze the change in best-corrected visual acuity (BCVA) in relation to demographics, diagnoses, management, and complications. Results: The study included 644 eyes of 491 patients. Patients with mild visual loss (logMAR 1.0) (P=0.002). Females were more likely to have mild visual loss as compared to males (P=0.025). Median overall BCVA was logMAR 0.18 at initial and final presentation (P=1.00). Vision loss at diagnosis was a predictor for moderate visual loss (MVL, logMAR 0.4 to

Stephanie B Engelhard,1 Zeina Haddad,1 Asima Bajwa,1 James Patrie,2 Wenjun Xin,2 Ashvini K Reddy1 1Department of Ophthalmology, 2Department of Public Health Sciences, University of Virginia, Charlottesville, VA, USA Purpose: To report the causes, clinical features, and outcomes of infectious uveitis in patients managed in a mid-Atlantic tertiary care center.Methods: Retrospective, observational study of infectious uveitis patients seen at the University of Virginia from 1984 to 2014.Results: Seventy-seven of 491 patients (15.7%) were diagnosed with infectious uveitis (mean age 58 years, 71.4% female, 76.6% Caucasian). The mean follow-up was 5 years. Anterior uveitis was the most common anatomic classification (39 patients, 50.6%) followed by panuveitis (20 patients, 26.0%) and posterior uveitis (18 patients, 23.4%). The most common infectious etiology was herpetic anterior uveitis (37 patients, 48.1%) followed by toxoplasma uveitis (14 patients, 18.2%). The most prevalent viral pathogen was varicella-zoster virus (21 patients, 27.3%) followed by herpes simplex virus (20 patients, 26.0%). Acute retinal necrosis (ARN) was diagnosed in 14 patients (18.2%). Aqueous humor yielded an etiologic diagnosis in seven (50%) of ARN patients, four of whom tested positive for cytomegalovirus and three for varicella-zoster virus. On presentation, 43 patients (55.8%) had a visual acuity (VA) better than 20/40 and 17 (22.1%) had a VA worse than 20/200. VA at the final follow-up was better than 20/40 in 39 patients (50.6%) and worse than 20/200 in 22 patients (28.6%). In all, 16 (20.8%) and 10 (13.0%) patients required cataract and vitrectomy surgery, respectively. A total of 14 patients (18.2%) were on glaucoma topical treatment and four (5.2%) required glaucoma surgery.Conclusion: The most common type of infectious uveitis seen over the study period was herpetic anterior uveitis secondary to varicella-zoster virus or herpes simplex virus, found to be most prevalent in patients over 60 years of age. This finding is comparable to other American epidemiologic studies. Ocular toxoplasmosis and ARN were also common causes of infectious uveitis. In all, 50.6% of patients had a VA better than 20/40 at the final follow-up visit, indicating the importance of prompt referral and appropriate treatment.

Stephanie B Engelhard, Vandan Patel, Ashvini K Reddy Department of Ophthalmology, University of Virginia, Charlottesville, VA, USA Background: The purpose of this study was to identify the causes, clinical features, and outcomes of intermediate uveitis, posterior uveitis, and panuveitis in patients managed in a mid-Atlantic tertiary care center.Methods: This was a retrospective observational study of intermediate uveitis, posterior uveitis, and panuveitis patients seen at the University of Virginia from 1984 to 2014. Results: One hundred and fifty-nine intermediate uveitis, posterior uveitis, and panuveitis patients (237 eyes) were identified. The patient population was 54.72% female; 67.30% of patients were Caucasian, and 22.01% were African–American. Mean age at diagnosis was 45.5 years. Mean duration of follow-up was 3.95 years. Mean number of visits to the clinic was 10.35. Of 491 uveitis patients, 26 (5.30%) had intermediate uveitis, 62 (12.60%) had posterior uveitis, and 71 (14.50%) had panuveitis. The leading diagnoses in the intermediate uveitis group were pars planitis (73.08%) and sarcoidosis (11.54%); toxoplasma uveitis (17.74%), multifocal choroiditis (14.52%), undifferentiated posterior uveitis (14.52%), and birdshot chorioretinitis (11.29%) in the posterior uveitis group; and undifferentiated panuveitis (29.58%), post-surgical panuveitis (18.31%), sarcoidosis (12.68%), acute retinal necrosis (12.68%), and toxoplasma uveitis (4.23%) in the panuveitis group. The most common treatment modalities included local steroids (57.23%) and systemic steroids (42.14%). Ocular hypertension was found in 38 patients (23.90%). Glaucoma surgery was performed in 18.24% of patients and cataract surgery in 21.38%. Mean best-corrected visual acuity was 0.66 logMAR at baseline across all anatomical locations and 0.57 logMAR at final follow-up. Best-corrected visual acuity improved or remained stable during follow-up in all groups. Conclusion: The most common diagnoses in our series by anatomical location were pars planitis (intermediate uveitis), toxoplasmosis (posterior uveitis), and undifferentiated uveitis (panuveitis). Panuveitis had significantly worse visual outcomes and higher rates of complications than did intermediate or posterior uveitis, a finding that confirms earlier reports. In this series, unilateral disease, regardless of anatomical location, was associated with poorer visual outcome, in contrast with the findings of other reports.

Stephanie B Engelhard, Asima Bajwa, Ashvini K ReddyDepartment of Ophthalmology, University of Virginia, Charlottesville, VA, USABackground: The purpose of this study was to report the demographics, disease characteristics, treatments, and visual outcomes of pediatric uveitis patients without juvenile idiopathic arthritis managed in a tertiary medical center.Methods: A retrospective, observational study was performed in pediatric uveitis patients without juvenile idiopathic arthritis and aged 0–18 years, who were seen at the University of Virginia from 1984 to 2014.Results: Thirty-nine pediatric uveitis patients (57 eyes) were identified. The patient population was 51.28% female, 51.28% Caucasian, and 33.33% African American. The mean age at diagnosis was 11.9 years. The mean duration of follow-up was 3.11 years. The mean number of visits to the clinic was 10.41. Of 57 eyes, 31 (54.39%) had anterior uveitis, 12 (21.05%) had intermediate uveitis, nine (15.79%) had posterior uveitis, and five (8.77%) had panuveitis. The leading diagnoses were traumatic uveitis (25.64%), undifferentiated anterior uveitis (17.95%), undifferentiated intermediate uveitis (15.38%), HLA-B27-associated anterior uveitis (7.69%), and herpetic anterior uveitis (7.69%). Systemic associations included sarcoidosis, ulcerative colitis, and psoriatic arthritis (n=3). The most common treatment modalities included local steroids (66.67%), systemic steroids (23.08%), and antimetabolites (20.51%). Ocular hypertension was found in five (12.82%) patients. Ocular surgery was performed in six (15.38%) patients. Mean best-corrected visual acuity (BCVA) at baseline across all anatomical locations was 0.458 logMAR, and was 0.411 logMAR at final follow-up. Mean BCVA improved during follow-up in all but the anterior uveitis group. The mean baseline intraocular pressure was 14.27 mmHg, and was 14.22 mmHg at final follow-up.Conclusion: Uveitis in childhood is a vision-threatening group of inflammatory disorders arising from numerous etiologies that vary geographically and historically. Because of the high burden of disease, the difficulty of making precise etiologic diagnoses, and the complicated management, it is imperative that affected children be referred to and closely monitored by uveitis specialists to prevent devastating ocular damage. This study found that BCVA and intraocular pressure did not vary significantly during follow-up, suggesting that close management by an ophthalmologist may prevent adverse visual outcomes, and highlighted the high prevalence of traumatic uveitis in children, which tends to have good visual outcomes.Keywords: uveitis, pediatric, visual acuity, intraocular pressure

Asima Bajwa,1 Diba Osmanzada,1 Susan Osmanzada,1 Irfan Khan,1 Jim Patrie,2 Wenjun Xin,2 Ashvini K Reddy1 1Department of Ophthalmology, 2Department of Public Health Sciences, University of Virginia, Charlottesville, VA, USA Purpose: To demonstrate the demographic, anatomic, and diagnostic classification of patients with uveitis seen in a tertiary care center in central Virginia.Methods: Retrospective chart review of patient demographics, disease characteristics, and disease severity-related outcomes (therapies, visual outcomes, and complications) from 1984 to 2014.Results: There were 491 patients (644 eyes) with mean age of 46 years (±21.4 years) and mean duration of follow up of 4.8 years (±6.8 years). Of these, 278 patients were female (56.6%). Further, 60.5% were Caucasian, and 27.3% were African American. The anatomic types seen were anterior uveitis (67.3%), panuveitis (14.5%), posterior uveitis (12.6%), and intermediate uveitis (5.3%). The most common etiology was post-traumatic (12.2%), followed by post-procedural (10.0%), herpetic (7.9%), human leukocyte antigen (HLA)-B27-associated (6.7%), and sarcoidosis (6.7%). Herpetic uveitis was more common among Caucasians than African Americans (sex-adjusted odds ratio [OR]: 7.69, 95% confidence interval [CI] [2.12, 50.00]), and sarcoidosis was more common among African Americans than Caucasians (sex-adjusted OR: 6.54, 95% CI [2.98, 15.29]). Herpetic anterior uveitis was more common among females than males (race-adjusted OR: 3.03, 95% CI [1.32, 7.71]). Multifocal choroiditis was more common among males than females (race-adjusted OR: 9.09, 95% CI [1.47, 100.00]). Mean logMAR visual acuity was 0.18 at initial and final visit. A total 388 (79%) and 133 (27.3%) patients received local and systemic steroids, respectively. A total 52 patients (10.6%) received an antimetabolite. A total 116 patients (23.7%) were managed with topical glaucoma medication. A total 43 (8.8%), 129 (26.4%), and 46 patients (9.4%) underwent glaucoma surgery, cataract surgery, and vitrectomy, respectively.Conclusion: Over the period of this study, Caucasian patients were more frequently seen than non-Caucasians, although African Americans constituted a considerable size of study population. The most common diagnoses were undifferentiated anterior uveitis, traumatic uveitis, post-procedural uveitis, herpetic disease, HLA-B27 associated uveitis, and sarcoidosis. Unlike previous reports, traumatic and post-procedural uveitis were frequently reported. Mean visual acuity remained stable from initial to final visit.

Ella H Leung,1 Ashvini K Reddy,2 Anil S Vedula,1 Harry W Flynn Jr1 1Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami, Miami, FL, 2Department of Ophthalmology, University of Virginia, Charlottesville, VA, USA Abstract: An 84-year-old female with a history of hypertension and dyslipidemia was referred for a retinal artery macroaneurysm with exudation that had extended into the macula. She underwent a total of six injections of bevacizumab, with some improvement in visual acuity and retinal thickness. Due to persistent macular edema, focal laser photocoagulation was performed around the macroaneurysm. The vision remained at 20/30 during 20 months of follow up. Although anti-vascular endothelial growth factor therapy may improve vision and decrease retinal thickness in retinal artery macroaneurysm, recalcitrant cases may be treated with laser photocoagulation to seal the leaking vessel.

A multicamera system for detecting cars and mapping them into parking spaces in a parking lot is described in this study. A limited number of sequences and without more difficult reality conditions (illumination changes and various weather conditions) were used to evaluate approaches from a cutting-edge system that function correctly under controlled conditions. However, the majority of them only provide parts of systems, typically detectors, rather than the entire system. The proposed system was made to work in real-world situations that take into account a variety of occlusion scenarios, changes in lighting, and weather. For the purpose of design and validation, a brand-new multicamera data set was recorded. Two of the system’s object detector results are shown, and several provided postprocessing stages are used to build the system. The findings clearly indicate that the suggested method works appropriately in demanding settings such as near entire occlusions, lighting variations, and varying weather conditions.

Background: Suxamethonium is considered as the “gold standard” for tracheal intubation. Because of innumerable contraindications for the use of this drug, there is a continuous search for other alternatives. Methods: In a prospective, randomized and double-blind study, we compared the intubating conditions and haemodynamic responses during rapid tracheal intubation using either suxamethonium or rocuronium with ephedrine pretreatment. We recruited 50 patients and allocated them into 2 groups (n= 25 each); Group S: received suxamethonium 1.5 mg/kg and Group R: received rocuronium 0.6 mg/ kg with ephedrine 100 µg/kg pretreatment. All patients were induced with 2 mg/kg propofol and intubation was attempted at 60 seconds. Haemodynamic responses and quality of intubating conditions were assessed. Results: Both groups were comparable in respect to age, sex, weight, Mallampati grade, Cormack Lehane grade and duration of laryngoscopy. Although both groups had clinically acceptable intubating conditions (good and excellent), there were more number of patients with better intubation score in Group S compared to Group R (p = 0.014). Conclusion: Suxamethonium still continues to be the “gold standard” for providing ideal tracheal intubation conditions. However, in conditions where suxamethonium is contraindicated, rocuronium-ephedrine combination can be used as an alternative to intubate the trachea at 60 seconds.

Malignant melanoma shows an unusual predilection to metastasize to small intestine. A patient with metastatic spread of malignant melanoma to small intestine is reported. This patient was operated for intestinal obstruction. Metastatic melanoma should be suspected in patients with malignant melanoma who develop gastrointestinal symptoms. [ABSTRACT FROM AUTHOR]

Purpose: While substantial research has focused on systemic immunomodulatory therapy for ocular cicatricial pemphigoid (OCP), limited data exist on managing associated ocular surface disease (OSD). This study evaluates treatments for OCP-related OSD at our institution., Methods: We conducted a retrospective analysis of patients diagnosed with cicatrizing conjunctivitis at the University of Colorado Hospital from January 1, 2013, to October 31, 2023. Patients with cicatrizing conjunctivitis due to non-OCP conditions were excluded, and disease severity was classified using the Foster Staging System., Results: Our review included 30 patients with OCP, all with at least six months of follow-up. The mean age of symptom onset ( n  = 19) was 62.2 years (SD = 16.4), while the mean age at diagnosis ( n  = 28) was 65.1 years (SD = 12.7). The most common OSD treatments at the last visit were preservative-free artificial tears (87%), topical corticosteroids (43%), autologous serum eye drops (40%), topical antibiotics (30%), and topical immunomodulators (23%). All patients used at least one treatment, with 83.3% on prescription therapies. Patients averaged 3.33 (SD: 1.4) treatments, with 1.7 (SD: 1.2) being prescriptions. Topical immunomodulators had the highest discontinuation rate at 73.1% ( n  = 19/26). Autologous serum eye drops and topical corticosteroids were the least discontinued treatments. Number of total treatments, prescriptions, and procedures sharply increased at stage three OCP., Conclusions: The number of treatments and procedures increased with OCP severity, indicating that advanced OCP often necessitated more intensive OSD management.

Background: Cytomegalovirus (CMV) chronic retinal necrosis (CRN) is a rare viral retinal infection that occurs in mildly immunocompromised people. It shares some features with both acute retinal necrosis and CMV retinitis. It is typically treated with combination intravitreal and systemic ganciclovir. We discuss the management of a case of CMV CRN with ganciclovir resistance., Case Presentation: An 80-year-old female presented with one month of blurry vision in the left eye. She was being treated with abatacept, methotrexate, and prednisone for rheumatoid arthritis. Examination revealed anterior chamber and vitreous cell along with peripheral retinal whitening. Fluorescein angiogram showed diffuse retinal non-perfusion. Aqueous fluid PCR testing returned positive for CMV. The retinitis was initially controlled with oral and intravitreal ganciclovir, but then recurred and progressed despite these therapies. Ganciclovir resistance was suspected and the patient was switched to intravitreal foscarnet injections, along with oral letermovir and leflunomide, which lead to resolution of the retinitis. The patient has now continued with letermovir and leflunomide for approximately 2.5 years without reactivation of the retinitis or need for further intravitreal anti-viral injections and with adequate control of her rheumatoid arthritis., Conclusion: The incidence of CMV CRN may increase in the future as the use of non-cytotoxic immunosuppressive therapies that result in relatively mild immunosuppression also increases. Treatment with ganciclovir is effective but frequently leads to resistance, as in our case. In this situation, combination therapy with letermovir and leflunomide, particularly in the setting of rheumatoid arthritis where leflunomide can also have an anti-inflammatory effect, can be considered., (© 2024.

Purpose: This study reports the outcomes of the 0.18-mg intravitreal fluocinolone acetonide implant in the treatment of pediatric noninfectious uveitis., Methods: A retrospective cohort study was performed on patients under 18 years old who received fluocinolone acetonide implant between June 1, 2020 and March 1, 2023. Data collected included demographics, uveitis diagnosis, use of anti-inflammatory therapy, visual acuity, intraocular pressure, and grading of uveitis activity. Uveitis recurrence was defined as increased inflammation that required additional anti-inflammatory therapy., Results: Eleven eyes from seven patients were included in this study. One patient (one eye) had a diagnosis of immune recovery uveitis and the remaining six patients (10 eyes) had pars planitis. The rate of remaining recurrence-free was 82% at 6 months, 60% at 12 months, and 60% at 24 months. Two of the six phakic eyes at baseline required cataract extraction during follow-up. Two of the four eyes that did not have intraocular pressure-lowering surgery before implantation required surgery in follow-up., Conclusion: The 0.18-mg fluocinolone acetonide implant has a similar efficacy for the treatment of pediatric uveitis, particularly pars planitis, as in the adult population, although with higher rates of ocular hypertension requiring intervention.

Purpose: To report a case series of patients with uveitic glaucoma who were treated with micropulse transscleral cyclophotocoagulation (mpCPC)., Methods: This retrospective case series consists of patients from the University of Colorado Sue Anschutz-Rodgers Eye Center from 2015 to 2020 who were diagnosed with uveitic glaucoma. Information collected includes demographic data, type of uveitis, glaucoma severity, and prior glaucoma surgeries. Pre- and postoperative best corrected visual acuity, intraocular pressure (IOP), glaucoma medications, degree of inflammation, and uveitis therapies were included up to 36 months postoperatively. Surgical success was defined as an IOP reduction of 30% with achievement of IOP goal using the same number of glaucoma medications or less at 6 months or 1 year. Uveitis success was defined as the absence of persistent anterior uveitis at 3 months., Results: Six patients and seven eyes with uveitic glaucoma underwent mpCPC. Types of uveitis included idiopathic anterior uveitis, HLA-B27-associated anterior uveitis, varicella zoster virus anterior uveitis, juvenile idiopathic arthritis-associated chronic anterior uveitis, lichen planus-associated intermediate uveitis, and sarcoidosis-associated panuveitis. Two of six eyes (33.3%) at 6 months and three of five eyes (60%) at 1 year achieved surgical success. Around 6 months postoperatively, two out of seven eyes (28.6%) required Ahmed glaucoma valve placement (n = 1) or repeat mpCPC (n = 1). One eye (14.3%) required phacoemulsification with goniotomy followed by an Ahmed glaucoma valve 18 months after mpCPC. There were no cases of persistent anterior uveitis, hypotony, or phthisis after mpCPC in this cohort., Conclusions: Micropulse transscleral cyclophotocoagulation may safely reduce intraocular pressure in some patients with uveitic glaucoma without exacerbation of intraocular inflammation. Multiple treatments may be required to achieve longer-term success., (© 2024. The Author(s).)

Purpose: The choroidal thickening and serous retinal detachments that characterize Vogt-Koyanagi-Harada (VKH) disease can be imaged in detail using spectral domain optical coherence tomography (SD-OCT). Whether specific qualitative and quantitative SD-OCT features at presentation were associated with visual outcomes in a randomized controlled trial comparing methotrexate to mycophenolate for steroid-sparing control of uveitis were evaluated., Methods: An exploratory subanalysis of data from the FAST trial in which SD-OCT images from VKH participants were analyzed for presence/absence of bacillary detachments, retinal pigment epithelium (RPE) folds, and internal limiting membrane (ILM) fluctuations was performed. A modified RPE undulation index was calculated to provide a quantifiable surrogate marker for choroidal folds., Results: SD-OCT images were available from 158 eyes with VKH. At baseline, bacillary detachments were present in 23.5% of eyes, RPE folds in 22.8% of eyes, and ILM fluctuations in 35.2% of eyes. For each 0.1 unit increase in modified RPE undulation index, there was an associated 0.13 increase in mean logMAR BSCVA at baseline. None of the SD-OCT features were associated with BSCVA at the 6-month primary endpoint. Indeed, mean final BSCVA was similar in those with and without the SD-OCT features of interest at baseline, and was between 0.1 and 0.2 logMAR (Snellen visual acuity 20/25 to 20/30)., Conclusions: While eyes with VKH may present with a variety of SD-OCT imaging pathology prior to starting immunosuppression with methotrexate or mycophenolate mofetil, final visual outcome in our study was excellent. With appropriate immunosuppression, good visual outcomes are possible in VKH.ClinicalTrials.gov Identifier NCT01829295Date of Registration: April 11, 2013.

Abstract: A 56-year-old woman presenting with swelling, redness, and pain in the left eye, initially treated with topical therapy for conjunctival squamous neoplasia, developed visual loss with progression of swelling in the left eye over the next year. Patient was referred for imaging as she also had significant weight loss and palpable neck swellings. Whole-body 18 F-FDG PET/CT revealed hypermetabolic left eye lesion; metastases in bilateral submandibular glands; cervical, mediastinal, and axillary lymph nodes; and a right lung nodule. Patient was diagnosed with ocular surface squamous cell carcinoma with metastases and started on systemic chemotherapy (cisplatin, paclitaxel, and 5-fluorouracil)., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: To evaluate the diagnostic value of QuantiFERON Gold (QFT-G) testing for ocular inflammation in a low prevalence tuberculosis (TB) area., Design: Diagnostic utility analysis., Methods: A review was performed for all uveitis patients who underwent QFT-G testing at the University of Colorado Eye Center from 2009 to 2022. Records were reviewed to assess QFT-G positivity rate and to identify which patients were tested for diagnostic purposes, defined as meeting the Standardization of Uveitis Nomenclature (SUN) criteria for tubercular uveitis (TBU): anterior uveitis with iris nodules, serpiginous-like choroiditis, choroidal nodule resembling a tuberculoma, multifocal choroiditis, or occlusive retinal vasculitis., Results: A total of 388 patients with uveitis underwent QFT-G testing, of which 17 (4.38%) were positive. Only one (5.88%) patient had true TBU with anterior uveitis with iris nodules. The remaining 16 (94.1%) patients did not meet SUN criteria for TBU and were incidentally found to be QFT-G positive during laboratory work-up prior to immunosuppression. The positive predictive value was 100% when QFT-G testing was performed in patients who met SUN criteria for TBU, whereas the positive predictive value was 0% for QFT-G testing performed in patients who did not meet SUN criteria for TBU., Conclusion: In low prevalence areas, the majority of QFT-G positive tests in uveitis patients are coincidental and unrelated to their uveitic disease process. The diagnostic value of a TB test is likely to be minimal unless the SUN clinical criteria for tubercular uveitis are met., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Purpose: Some patients taking methotrexate (MTX) or mycophenolate mofetil (MMF) experience intolerable side effects at full doses. We evaluated whether dose reduction affected treatment outcomes in uveitis patients., Methods: Subanalysis of the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial. Patients were randomized to receive MTX (25 mg weekly) or MMF (3 g daily). A pre-specified dose reduction protocol could be employed for intolerable side effects. Primary analysis was performed at 6 months., Results: 43/194 patients (22%) required dose reduction. 88/151 patients (58%) on maximum doses and 32/43 patients (74%) on reduced doses were deemed treatment successes at 6 months. The odds ratio point estimate (1.60, 95% CI 0.72-3.74) favored dose-reduction but this was not significant. Following reduction, adverse events improved at the subsequent study visit (79 events reduced to 63 events)., Conclusion: Dose reduction of antimetabolites was not associated with worse outcomes in this subanalysis of a uveitis trial.

Background: Prevention of diabetes in the general population can help reduce the incidence of tuberculosis. Hence it is necessary to document that diabetes is strongly associated with tuberculosis as a risk factor., Objective: To study if diabetes is associated with tuberculosis compared to controls., Materials and Methods: A community based case-control study was carried out. 215 newly diagnosed cases of tuberculosis on treatment for not more than three months were selected randomly from the randomly selected tuberculosis unit. 215 neighbourhood controls were selected. They were matched for the age group of ± 10 years and sex. Fasting blood sugar (FBS) was estimated using a glucometer., Results: Tobacco chewing, residence and family history of TB were significantly more in cases ( P < 0.05). Mean BMI was significantly lower in cases compared to controls. The proportion of TB cases among the known cases of diabetes was 67% compared to 33% in controls, which was statistically significant. Mean FBS was significantly higher in cases compared to controls ( P < 0.05). The odds of cases being diabetic was 2.456 times more than those of controls. On binary logistic regression, diabetes was an independent risk factor for tuberculosis. Other independent risk factors were tobacco chewing, and family history of TB., Conclusion: Family history of tuberculosis, and tobacco chewing were positively associated with tuberculosis whereas body mass index was negatively associated with tuberculosis. Diabetes was significantly associated with tuberculosis., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Indian Journal of Community Medicine.)

Introduction: To achieve epidemic control of infectious diseases, engaging higher-burden populations with accessible diagnostic services is critical. HIV self-testing (HIVST) is a promising option., Methods: We implemented an online HIVST programme for key populations across India. Eligible clients were 18 years or older, self-reported a negative or unknown HIV status and reported not taking antiretroviral therapy. Clients who reported a prior HIV diagnosis were not eligible to receive an HIVST kit. HIVST clients received kits via courier or in person at pre-determined pick-up points supported by trained counselling staff. Virtual counsellors engaged clients online and by phone and offered support to register, access, and complete HIVST free of cost. Virtual counsellors supported clients to report results and engage with follow-up services. Follow-up included linking clients with a positive result to confirmatory testing and HIV care services. We assessed programmatic data across HIV continuum outcomes and conducted a qualitative evaluation through interviews with purposively sampled clients., Results: Between 30 June 2021 and 30 September 2022, 5324 clients ordered an HIVST kit (76% men, 13% women, 7% transgender people, 4% unknown gender). Of the 4282 clients reporting results (94% of those who received a kit), 6% screened positive, among whom 72% (n = 184) completed confirmatory testing. Themes from 41 client interviews included satisfaction about the convenience and privacy of services and the discreet nature of kit delivery. Respondents were drawn to the convenience of HIVST and appreciated gaining courage and comfort throughout the process from virtual counsellor support. For respondents who screened positive, challenges to care linkage included fearing judgemental questions from public providers and wanting more time before starting treatment. Clients shared concerns about kit accuracy and suggested that instructional materials be provided with more diverse language options., Conclusions: Web-based HIVST services with tailored support appeared to facilitate HIV service access and engagement of harder-to-reach populations across India. Assistance from a community-oriented counsellor proved important to overcome literacy barriers and mistrust  in order to support the HIVST process and service linkage. Learnings can inform global efforts to improve the critical step of diagnosis in achieving epidemic control for HIV and other infectious diseases., (© 2024 The Author(s).

This study evaluates the cytocompatibility of cerium-doped mesoporous bioactive glasses (Ce-MBGs) loaded with polyphenols (Ce-MBGs-Poly) for possible application in bone tissue engineering after tumour resection. We tested MBGs powders and pellets on 2D and 3D in vitro models using human bone marrow-derived mesenchymal stem cells (hMSCs), osteosarcoma cells (U2OS), and endothelial cells (EA.hy926). Promisingly, at a low concentration in culture medium, Poly-loaded MBGs powders containing 1.2 mol% of cerium inhibited U2OS metabolic activity, preserved hMSCs viability, and had no adverse effects on EA.hy926 migration. Moreover, the study discussed the possible interaction between cerium and Poly, influencing anti-cancer effects. In summary, this research provides insights into the complex interactions between Ce-MBGs, Poly, and various cell types in distinct 2D and 3D in vitro models, highlighting the potential of loaded Ce-MBGs for post-resection bone tissue engineering with a balance between pro-regenerative and anti-tumorigenic activities., Competing Interests: The authors do not have any conflicts of interest to declare., (© 2024 The Author(s).)

Alzheimer's Disease (AD) is a global health issue, affecting over 6 million in the United States, with that number expected to increase as the aging population grows. As a neurodegenerative disorder that affects memory and cognitive functions, it is well established that AD is associated with cardiovascular risk factors beyond only cerebral decline. However, the study of cerebrovascular techniques for AD is still evolving. Here, we provide reproducible methods to measure impedance-based pulse wave velocity (PWV), a marker of arterial stiffness, in the systemic vascular (aortic PWV) and in the cerebral vascular (cerebral PWV) systems. Using aortic impedance and this relatively novel technique of cerebral impedance to comprehensively describe the systemic vascular and the cerebral vascular systems, we examined the sex-dependent differences in 5x transgenic mice (5XFAD) with AD under normal and high-fat diet, and in wild-type mice under a normal diet. Additionally, we validated our method for measuring cerebrovascular impedance in a model of induced stress in 5XFAD. Together, our results show that sex and diet differences in wildtype and 5XFAD mice account for very minimal differences in cerebral impedance. Interestingly, 5XFAD, and not wildtype, male mice on a chow diet show higher cerebral impedance, suggesting pathological differences. Opposingly, when we subjected 5XFAD mice to stress, we found that females showed elevated cerebral impedance. Using this validated method of measuring impedance-based aortic and cerebral PWV, future research may explore the effects of modifying factors including age, chronic diet, and acute stress, which may mediate cardiovascular risk in AD., Competing Interests: Disclosures Dr. Reddy is a collaborator and consultant with Indus Instruments, Webster, TX.

Context: Patients experiencing pain from femoral acetabular impingement and considering hip arthroscopy may be concerned about their timeline to resume activities they enjoy, such as golf., Objective: The purpose of this study was to review current literature on return-to-play data after hip arthroscopy and to provide clinicians with data to set proper expectations with patients., Data Sources: The following terms were used to search PubMed and Embase electronic databases on October 18, 2023: hip, arthroscopy, arthroscopic, golf., Study Selection: Studies were included if they were in the English language, of Level 1 to 4 evidence, and contained data specific to golfers undergoing hip arthroscopy. Studies were excluded if they did not designate participants as golfers or did not specify return-to-play data. Editorials, case reports, and review articles were excluded. Screening was completed by 2 authors in a blind and duplicate manner., Study Design: Systematic review., Level of Evidence: Level II., Data Extraction: The following datapoints were extracted from each study: hip pathology and arthroscopic procedure data; number of players returning to golf and time from surgery to return; outcome score(s); and rehabilitation details. Descriptive statistics were calculated using Comprehensive Meta-Analysis software., Results: The search returned 400 studies, of which 4 were included for analysis. Of these 4 studies, 2 specified return-to-play time. Of 95 golfers, 90 (94.7%) returned to golf successfully after arthroscopic hip surgery. Subjective and objective outcome scores improved postoperatively, including an increased average drive distance., Conclusion: Return to golf after hip arthroscopy is highly probable, with approximately 95% of patients throughout literature returning to play. A mean return time of 4.7 months for professional golfers and 7.2 months for amateurs, alongside improved subjective outcomes and performance metrics postsurgery, suggest patients can expect a relatively quick return to the course with similar or improved performance., Competing Interests: The authors report no potential conflicts of interest in the development and publication of this article.

Drug-resistant bacteria are emerging as a global threat, despite frequently being less fit than their drug-susceptible ancestors 1-8 . Here we sought to define the mechanisms that drive or buffer the fitness cost of rifampicin resistance (RifR) in the bacterial pathogen Mycobacterium tuberculosis (Mtb). Rifampicin inhibits RNA polymerase (RNAP) and is a cornerstone of modern short-course tuberculosis therapy 9,10 . However, RifR Mtb accounts for one-quarter of all deaths due to drug-resistant bacteria 11,12 . We took a comparative functional genomics approach to define processes that are differentially vulnerable to CRISPR interference (CRISPRi) inhibition in RifR Mtb. Among other hits, we found that the universally conserved transcription factor NusG is crucial for the fitness of RifR Mtb. In contrast to its role in Escherichia coli, Mtb NusG has an essential RNAP pro-pausing function mediated by distinct contacts with RNAP and the DNA 13 . We find this pro-pausing NusG-RNAP interface to be under positive selection in clinical RifR Mtb isolates. Mutations in the NusG-RNAP interface reduce pro-pausing activity and increase fitness of RifR Mtb. Collectively, these results define excessive RNAP pausing as a molecular mechanism that drives the fitness cost of RifR in Mtb, identify a new mechanism of compensation to overcome this cost, suggest rational approaches to exacerbate the fitness cost, and, more broadly, could inform new therapeutic approaches to develop drug combinations to slow the evolution of RifR in Mtb., (© 2024.

Purpose of Review: Pulse wave velocity (PWV) is an important and well-established measure of arterial stiffness that is strongly associated with aging. Age-related alterations in the elastic properties and integrity of arterial walls can lead to cardiovascular disease. PWV measurements play an important role in the early detection of these changes, as well as other cardiovascular disease risk factors, such as hypertension. This review provides a comprehensive summary of the current knowledge of the effects of aging on arterial stiffness, as measured by PWV., Recent Findings: This review highlights recent findings showing the applicability of PWV analysis for investigating heart failure, hypertension, and other cardiovascular diseases, as well as cerebrovascular diseases and Alzheimer's disease. It also discusses the clinical implications of utilizing PWV to monitor treatment outcomes, various challenges in implementing PWV assessment in clinical practice, and the development of new technologies, including machine learning and artificial intelligence, which may improve the usefulness of PWV measurements in the future. Measuring arterial stiffness through PWV remains an important technique to study aging, especially as the technology continues to evolve. There is a clear need to leverage PWV to identify interventions that mitigate age-related increases in PWV, potentially improving CVD outcomes and promoting healthy vascular aging., (© 2023.

We report a case of intermediate uveitis in the setting of both systemic sarcoidosis and multiple sclerosis. A 68-year-old female was diagnosed with bilateral granulomatous intermediate uveitis and cystoid macular edema. Initial systemic work-up was unrevealing. The uveitis was treated successfully with local corticosteroid injections. Eighteen months after presentation, the patient developed new systemic symptoms. Additional testing revealed systemic lymphadenopathy, with biopsy showing non-caseating granulomas, leading to a diagnosis of sarcoidosis. However, MRI of the brain and spinal cord along with cerebrospinal fluid analysis was consistent with MS. The management of the uveitis and systemic inflammation was co-managed by ophthalmology, neurology, and rheumatology, and eventually controlled with leflunomide and rituximab. Patients can rarely have co-existing systemic sarcoidosis and multiple sclerosis. Although challenging to diagnose, radiographic findings and cerebrospinal fluid analysis can be helpful to differentiate multiple sclerosis and neurosarcoidosis. Management of these patients requires coordination between multiple specialties.

Background: Sub-Tenon's triamcinolone acetonide (STA) is less effective than intravitreal corticosteroids in the treatment of uveitic macular edema (ME), but does have some relative advantages, including substantially lower cost and decreased risk of post-injection ocular hypertension. It would be useful for clinicians to know which eyes may respond well to STA and not necessarily require intravitreal therapy. The objective of this study is to identify risk factors for failing STA for the treatment of uveitic ME., Main Body: A retrospective cohort study was performed. Medical records were reviewed of patients who underwent STA for the treatment of uveitic ME between January 1, 2013, and July 31, 2022, at the University of Colorado Hospital. Uveitic ME was defined by a central subfield thickness (CST) greater than 320 μm or the presence of intra-retinal cystoid spaces on optical coherence tomography (OCT), or by the presence of petaloid macular leakage on fluorescein angiography (FA). Data collected included age, race/ethnicity, sex, history of diabetes mellitus, anatomic classification of uveitis, use of corticosteroids, use of immunomodulatory therapy, presence of intra-retinal fluid on OCT, CST on OCT, and presence of petaloid macular leakage on FA. STA failure was defined as the need for additional therapy within 12 weeks of STA due to persistent or worsening uveitic ME. One hundred eighty eyes from 131 patients were included. Forty-two eyes (23.3%) were considered treatment failures. In univariate and multivariable analysis, higher baseline CST was associated with a higher likelihood of failing STA (OR 1.17 for each 30 μm increase in CST, P = 0.016)., Conclusions: STA, while not as potent as intravitreal corticosteroids for the treatment of uveitic ME, was still an effective therapy, particularly for patients with lower baseline CST. Given its lower side effect profile and cost compared to intravitreal treatments, clinicians could consider STA as an initial treatment for mild uveitic ME., (© 2024. The Author(s).)

A 67-year-old female presented with shortness of breath, weight loss, abdomen, and back pain for 2 months. Ultrasound of the abdomen revealed multiple focal liver lesions. 18 F-Fluorodeoxyglucose whole-body positron emission tomography/computed tomography revealed a hypermetabolic lesion in the suprahepatic inferior vena cava extending into the right atrium. Multiple hypermetabolic lesions were seen in liver, bones, and abdominal lymph nodes, suggestive of metastases. Histopathology and immunohistochemistry of the lesions revealed it to be metastatic leiomyosarcoma., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Indian Journal of Nuclear Medicine.)

Introduction: While phacoemulsification cataract extraction is generally highly effective and safe, patients with a history of uveitis are at higher risk for postoperative complications and often require a modified perioperative medication regimen. No data exists on risks of postoperative complications and persistent anterior uveitis (PAU) in patients with non-ocular autoimmune disease., Methods: Medical records were reviewed of patients who underwent phacoemulsification cataract surgery with intraocular lens implantation between January 1, 2014 and December 31, 2019 at the University of Colorado Hospital (UCH) as part of a retrospective cohort study. Exclusion criteria included patient history of ocular inflammation and cataract surgery combined with another intraocular surgery. Patients were only included as having autoimmune disease if the diagnosis was confirmed by a relevant specialist at UCH. Patients with autoimmune disease were then stratified into systemic versus organ-specific autoimmune disease, and patients with systemic autoimmune disease were further stratified into immunosuppressed and not immunosuppressed at the time of cataract surgery. Patients with PAU were identified according to the Standardization of Uveitis Nomenclature Working Group. Data including sex, race/ethnicity, intraoperative cumulative dissipated energy (CDE), and postoperative best-corrected visual acuity (BCVA) and intraocular pressure (IOP) were obtained., Results: A total of 422 eyes from 248 patients had confirmed autoimmune disease, compared to a control group of 10,201 eyes. The autoimmune and systemic autoimmune disease groups were not more likely to have postoperative complications or PAU compared to the control group. Immunosuppression status among the systemic autoimmune disease group was also not associated with postoperative complications or PAU., Conclusion: Patients with non-ocular autoimmune disease do not appear to be at higher risk for postoperative complications, including worse BCVA or increased rates of IOP elevation and PAU, following phacoemulsification cataract surgery. These patients do not appear to require modification of the typical perioperative medication regimen., (© 2023. The Author(s).)

During aging, muscle gradually undergoes sarcopenia, the loss of function associated with loss of mass, strength, endurance, and oxidative capacity. However, the 3D structural alterations of mitochondria associated with aging in skeletal muscle and cardiac tissues are not well described. Although mitochondrial aging is associated with decreased mitochondrial capacity, the genes responsible for the morphological changes in mitochondria during aging are poorly characterized. We measured changes in mitochondrial morphology in aged murine gastrocnemius, soleus, and cardiac tissues using serial block-face scanning electron microscopy and 3D reconstructions. We also used reverse transcriptase-quantitative PCR, transmission electron microscopy quantification, Seahorse analysis, and metabolomics and lipidomics to measure changes in mitochondrial morphology and function after loss of mitochondria contact site and cristae organizing system (MICOS) complex genes, Chchd3, Chchd6, and Mitofilin. We identified significant changes in mitochondrial size in aged murine gastrocnemius, soleus, and cardiac tissues. We found that both age-related loss of the MICOS complex and knockouts of MICOS genes in mice altered mitochondrial morphology. Given the critical role of mitochondria in maintaining cellular metabolism, we characterized the metabolomes and lipidomes of young and aged mouse tissues, which showed profound alterations consistent with changes in membrane integrity, supporting our observations of age-related changes in muscle tissues. We found a relationship between changes in the MICOS complex and aging. Thus, it is important to understand the mechanisms that underlie the tissue-dependent 3D mitochondrial phenotypic changes that occur in aging and the evolutionary conservation of these mechanisms between Drosophila and mammals., (© 2023 The Authors.

With sparse treatment options, cardiac disease remains a significant cause of death among humans. As a person ages, mitochondria breakdown and the heart becomes less efficient. Heart failure is linked to many mitochondria-associated processes, including endoplasmic reticulum stress, mitochondrial bioenergetics, insulin signaling, autophagy, and oxidative stress. The roles of key mitochondrial complexes that dictate the ultrastructure, such as the mitochondrial contact site and cristae organizing system (MICOS), in aging cardiac muscle are poorly understood. To better understand the cause of age-related alteration in mitochondrial structure in cardiac muscle, we used transmission electron microscopy (TEM) and serial block facing-scanning electron microscopy (SBF-SEM) to quantitatively analyze the three-dimensional (3-D) networks in cardiac muscle samples of male mice at aging intervals of 3 mo, 1 yr, and 2 yr. Here, we present the loss of cristae morphology, the inner folds of the mitochondria, across age. In conjunction with this, the three-dimensional (3-D) volume of mitochondria decreased. These findings mimicked observed phenotypes in murine cardiac fibroblasts with CRISPR/Cas9 knockout of Mitofilin, Chchd3, Chchd6 (some members of the MICOS complex), and Opa1 , which showed poorer oxidative consumption rate and mitochondria with decreased mitochondrial length and volume. In combination, these data show the need to explore if loss of the MICOS complex in the heart may be involved in age-associated mitochondrial and cristae structural changes. NEW & NOTEWORTHY This article shows how mitochondria in murine cardiac changes, importantly elucidating age-related changes. It also is the first to show that the MICOS complex may play a role in outer membrane mitochondrial structure.

Introduction: Clinical trial registry searches for unpublished clinical trial data are a means of mitigating publication bias within systematic reviews (SRs). The purpose of our study is to look at the rate of clinical trial registry searches conducted by SRs in the top five Plastic and Reconstructive Surgery journals., Methods: We identified the top five plastic and reconstructive surgery journals using the Google h-5 index. We then searched Pubmed for SRs published in these journals and compared them to plastic surgery SRs published in the Cochrane Collaboration for SRs over the last 5 y. We included all SRs that were published within these top five journals and Cochrane between December 6, 2016 and December 6, 2021. We then conducted a secondary analysis on clinicaltrials.gov looking for unpublished clinical trials for 100 randomized SRs that did not conduct a clinical trial registry search., Results: In SRs, 3.3% (17/512) from plastic surgery journals conducted trial registry searches. In comparison, 95.0% (38/40) of Cochrane Collaboration SRs conducted trial registry searches. Our secondary analysis found that 50% (50/100) of SRs could have included at least one unpublished clinical trial data set., Conclusions: We found that plastic surgery SRs rarely include searches for unpublished clinical trial data in clinical trial registries. To improve the data completeness of SRs in plastic surgery journals, we recommend journals alter their author guidelines to require a clinical trial registry search for unpublished literature., (Copyright © 2023 Elsevier Inc.
