A rebubble procedure was performed in 19 of 134 (14.2%); of those, the average number of rebubbling procedures performed was 1.13 (range, 1-2). Primary failure occurred in 6 of 134 (4.5%).Twelve-month graft survival occurred in 122 of 134 eyes (91.0%), with secondary failure within the first 12 months accounting for failure of 6 of 134 (4.5%). Nine of 134 (6.7%) cases had a recorded episode of endothelial rejection. The average time for rejection episode was 9.5 months (range, 1-20 months) after surgery.

A total of 134 'posture-less' DMEKs did not suffer very high rates of graft detachment, rebubbling, or other postoperative complications, even with immediate erect posturing after surgery.

To determine the relationship between tear film interferometric patterns and properties of lipid, including rheological properties.

Prospective, cross-sectional laboratory investigation.

This study included 105 subjects (94 dry eye patients and 11 normal participants). The subjects were divided into 3 categories (group 1, normal; group 2, thin; and group 3, irregular) according to interferometric patterns. According to tear interferometric patterns, ultra-performance liquid chromatography (LC) quadrupole-linear ion trap/mass spectrometry (MS)-based analysis was used to investigate lipid profiling of meibum. Rheological properties were examined by using a Langmuir-Blodgett trough with saline solution.

Normal subjects showed Pearl-like patterns, and dry eye patients showed either irregular or thin patterns. Group 2 tended to be the evaporative type, and group 3 tended to be the aqueous-deficient type. Lipid profiling using LC-MS identified 280 lipid species of 25 lipid classes. In the meibum of the patient groups, the content of cholesteryl esters and nonpolar lipids was lower than that in the normal group. However, the content of polar lipids such as sphingolipids and phospholipids in the patient groups was higher than that in the normal group. Rheological properties showed that the lift-off areas were comparable among the 3 groups and the surface tension was the highest in group 1, followed by group 3 and group 2.

The findings of this study suggest that tear interferometric patterns are associated with lipid profiling of meibum and its rheological properties. These results may contribute toward the development of new treatment modalities.

To evaluate the rates of ghost and honorary authorship in ophthalmology and to determine risk factors associated with ghost and honorary authorship.

Cross-sectional survey.

Corresponding authors of articles published in Ophthalmology, JAMA Ophthalmology, and the American Journal of Ophthalmology from June 2019 to December 2020 were emailed an electronic survey. The rates of ghost and honorary authorship, demographic characteristics of the corresponding authors with and without ghost and honorary authorship, and risk factors for ghost and honorary authorship were evaluated.

Corresponding authors (n=830) were emailed a survey and 278 total responses (34.1%) were received; 227 responses (27.9%) were complete and included for analysis. Most respondents (n=206, 90.7%) believed that the International Committee of Medical Journal Editors (ICMJE) guidelines for authorship adequately address criteria for authorship. Twenty-seven corresponding authors (11.9%) reported characteristics of their articles that indiublications honorarily and excluding authors who qualify for authorship are relatively common practices in ophthalmological research. Further investigation into the drivers of honorary and ghost authorship practices in ophthalmology, and the effectiveness of preventive measures are needed to ensure fair authorship attributions.

To characterize the frequency, severity, and resolution of hearing dysfunction in patients treated with teprotumumab for thyroid eye disease (TED).

Prospective observational case series.

Ophthalmic examination and adverse event assessment, including otologic symptoms, were performed at baseline, after infusions 2, 4, and 8, and at 6-month follow-up in consecutive patients who received at least 4 teprotumumab infusions. Laboratory test results were collected at baseline and during treatment. Audiometry, patulous eustachian tube (PET) testing, and otolaryngology evaluation were obtained for patients with new or worsening otologic symptoms, with a subset obtaining baseline and posttreatment testing.

Twenty-seven patients were analyzed (24 females, 3 males, average 56.3 years old). Twenty-two patients (81.5%) developed new subjective otologic symptoms, after a mean of 3.8 infusions (SD 1.8). At 39.2-week average follow-up after the last infusion, most patients with tinnitus (100%), ear plugging/fullness (be further studied. Until risk factors for hearing loss are better understood, we recommend baseline audiometry with PET testing and repeat testing if new otologic symptoms develop. Screening, monitoring, and prevention guidelines are needed.

To report the 1-year results of human amniotic membrane patch implantation for optic disc pit maculopathy.

A prospective, consecutive, interventional study.

Eleven eyes of 11 patients affected by optic disc pit maculopathy associated with subretinal/intraretinal fluid were included in this single-institution study. A 25-gauge pars plana vitrectomy was performed in all cases, with an implant of a human amniotic membrane patch into the optic disc pit and air was injected as endotamponade. The primary study outcome was the subretinal and intraretinal fluid reabsorption. Secondary outcomes were visual acuity improvement and postoperative complications.

Mean central retinal thickness gradually diminished from 512 ± 137 µm to 243 ± 19 µm, at the 12-month follow-up. The mean visual acuity improved from 20/80 at baseline to 20/32 at the 12-month follow-up. Complete fluid resorption occurred in 9 of 11 (81.8%) eyes and there was partial resorption in 2 eyes (18%). No subretinal fluid recurrence was observed during the 12-month follow-up. No intraoperative or postoperative complications were reported during the follow-ups. The amniotic membrane patch remained detectable inside the pit for the entire follow-up time.

An amniotic membrane plug may be effective for improving optic disc pit maculopathy. All cases had an anatomical improvement and encouraging visual acuity recovery.

Mitochondrial structural and functional aberrations due to an imbalance in mitochondrial fusion/fission processes are implicated in the pathogenesis of chronic kidney disease. Therefore, we investigated macrophage-specific functions of mitochondrial fusion proteins, mitofusin (MFN)1 and MFN2, in modulating macrophage mitochondrial dynamics, biogenesis, oxidative stress, polarization, and fibrotic response. MFN1 and MFN2 were found to be suppressed in mice after adenine diet-induced chronic kidney disease, in transforming growth factor-beta 1-treated bone marrow-derived macrophages, and in THP-1-derived human macrophages (a human leukemic cell line). However, abrogating Mfn2 but not Mfn1 in myeloid-lineage cells resulted in greater macrophage recruitment into the kidney during fibrosis and the macrophage-derived fibrotic response associated with collagen deposition culminating in worsening kidney function. Myeloid-specific Mfn1 /Mfn2 double knockout mice also showed increased adenine-induced fibrosis. Mfn2-deficient bone marrow-derived macrophages displayed enhanced polarization towards the profibrotic/M2 phenotype and impaired mitochondrial biogenesis. Macrophages in the kidney of Mfn2-deficient and double knockout but not Mfn1-deficient mice exhibited greater mitochondrial mass, size, oxidative stress and lower mitophagy under fibrotic conditions than the macrophages in the kidney of wild-type mice. Thus, downregulation of MFN2 but not MFN1 lead to macrophage polarization towards a profibrotic phenotype to promote kidney fibrosis through a mechanism involving suppression of macrophage mitophagy and dysfunctional mitochondrial dynamics.Single-kidney glomerular filtration rate (GFR) increases after living kidney donation due to compensatory hyperfiltration and structural changes. The implications of inter-individual variability in this increase in single-kidney GFR are unknown. Here, we aimed to identify determinants of the increase in single-kidney GFR at three-month postdonation, and to investigate its relationship with long-term kidney function. In a cohort study in 1024 donors, we found considerable inter-individual variability of the early increase in remaining single-kidney estimated GFR (eGFR) (median [25th-75th percentile]) 12 [8-18] mL/min/1.73m2. Predonation eGFR, age, and cortical kidney volume measured by CT were the main determinants of the early postdonation increase in single-kidney eGFR. Individuals with a stronger early increase in single-kidney eGFR had a significantly higher five-year postdonation eGFR, independent of predonation eGFR and age. Addition of the postdonation increase in single-kidney eGFR to a model including predonation eGFR and age significantly improved prediction of a five-year postdonation eGFR under 50 mL/min/1.73m2. Results at ten-year follow-up were comparable, while accounting for left-right differences in kidney volume did not materially change the results. Internal validation using 125I-iothalamate-based measured GFR in 529 donors and external validation using eGFR data in 647 donors yielded highly similar results. Thus, individuals with a more pronounced increase in single-kidney GFR had better long-term kidney function, independent of predonation GFR and age. Hence, the early postdonation increase in single-kidney GFR, considered indicative for kidney reserve capacity, may have additional value to eGFR and age to personalize follow-up intensity after living kidney donation.Acute kidney injury (AKI) is a life-threatening condition that is one of most common side effects of cisplatin therapy. Fatty acid oxidation (FAO) is the main source of energy production in kidney proximal tubular epithelial cells (PTECs) but it is inhibited in AKI. Recent work demonstrated that activation of the farnesoid X receptor (FXR) protects against AKI, but the underlying mechanism remains elusive. click here Using a model of cisplatin-induced AKI, we found that FXR and FAO-related genes were remarkably downregulated while kidney lipid accumulated. Proximal tubule-specific or whole body FXR knockout worsened, while pharmacological activation attenuated these effects. Conversely, FXR knockout in non-proximal tubules did not. RNA-sequencing of PTECs demonstrated increased transcripts involved in metabolic pathways in cells overexpressing FXR versus control after cisplatin treatment, specifically transcripts associated with FAO and peroxisome proliferator-activated receptor-γ (PPARγ) signaling. Furthermore, FXR overexpression or activation improved FAO and inhibited intracellular lipid accumulation in cisplatin-treated cells.
