Aims: The aim of this study was to evaluate the rate of infectious and noninfectious endophthalmitis after an intravitreal injection of bevacizumab.
Methods: This clinical interventional case-series study included 1218 intravitreal injections of 1.5 mg of bevacizumab consecutively performed for 684 eyes with exudative age-related macular degeneration. Among the injections were 534 reinjections. Follow-up after each injection was at least 4 weeks.
Results: One (1) eye developed an infectious endophthalmitis 3 days after a second injection. In none of the other eyes, were signs of an infectious or noninfectious endophthalmitis observed with the cellular infiltration or amorphous opacification of the vitreous as marked by the Tyndall phenomenon in the anterior chamber, retinal infiltration, or pain.
Conclusions: The rate of infectious endophthalmitis after an intravitreal injection of 1.5 mg bevacizumab may be approximately 1:1000, similar to injections of other drugs available thus far.

A high-throughput, microplate reader-based method to monitor in vitro HIV latency reversal in the absence of flow cytometry.

J-Lat cells are derivatives of the Jurkat CD4 T cell line that contain a non-infectious, inducible HIV provirus with a GFP tag. While these cells have substantially advanced our understanding of HIV latency, their use by many laboratories in low and middle-income countries is restricted by limited access to flow cytometry. To overcome this barrier, we describe a modified J-Lat assay using a standard microplate reader that detects HIV-GFP expression following treatment with latency-reversing agents (LRAs).

Purpose: To evaluate the efficacy and safety of weekly adalimumab (ADA) treatment in non-infectious uveitis (NIU) patients, including both pediatric and adult populations, and identify factors influencing treatment efficacy.
Methods: A retrospective cohort study at two hospitals in Türkiye included 51 NIU patients (29 children, 22 adults) who escalated from bi-weekly to weekly ADA due to inadequate disease control. Data on six clinical parameters (anterior chamber reaction, vitreous haze, visual acuity, central macular thickness [CMT], prednisone use, uveitis flare-up frequency), adverse effects, and treatment-related factors were collected.
Prevalence of Gastroesophageal Reflux in Interstitial Lung Diseases Clinic.

Background Interstitial lung diseases (ILDs) are a group of non-infectious diseases characterized by interstitial inflammation and fibrosis on histological examination. Gastroesophageal reflux disease (GERD) is common in this patient population, but whether there is a causal or coincidental relationship is not yet clear. It still remains unsettled how to diagnose GERD, and the role of different treatment modalities for GERD, in these lung disorders.

Aspergillosis is the most commonly and widely reported fungal infection in birds. Disease development is often secondary to stressors that cause immunocompromise, and it is typically regarded as a disease of captivity. We retrospectively evaluated data from 133 birds diagnosed with aspergillosis at the Southeastern Cooperative Wildlife Disease Study from 2001-2023 to assess diversity and relative frequency across avian taxa, gross and histologic lesion patterns, and comorbidities.

Background: Pneumocystis jirovecii colonization rates in healthy patients are unclear. Previously published studies suggest that the fungus could play a role in the physiopathology and progression of chronic respiratory diseases.
Aims: The goal of this study was to determine the prevalence of colonization by this fungus in the lower respiratory tract of immunocompetent patients who are not at risk of dysbiosis.
