Diabetic retinopathy (DR) is a common complication of diabetes characterized by vascular pathology and neuroinflammation. Pentraxin 3 (PTX3) is a soluble pattern recognition molecule that functions at the crossroads between innate immunity, inflammation, and tissue remodeling. DR is known to involve inflammatory pathways, although the potential relevance of PTX3 has not been explored.

A secondary objective was to compare the sensitivity and specificity of RT-PCR to anti-Histoplasma immunoglobulin G antibody detection by enzyme immunoassay (IgG-EIA) and IgG-EIA to UA-EIA.
Animals: Cats presented to the Kansas State University Veterinary Health Center from February through September of 2023 in which histoplasmosis was diagnosed or suspected.
Background: Ischemia with no obstructive coronary arteries is frequently caused by coronary microvascular dysfunction (CMD). Consensus diagnostic criteria for CMD include baseline angiographic slow flow by corrected TIMI (Thrombolysis In Myocardial Infarction) frame count (cTFC), but correlations between slow flow and CMD measured by invasive coronary function testing (CFT) are uncertain.
Objectives: The aim of this study was to investigate relationships between cTFC and invasive CFT for CMD.
Background: Coronary slow flow (CSF) by invasive coronary angiography is frequently understood to be an indicator of coronary microvascular dysfunction (CMD) in patients with ischemia with nonobstructive coronary arteries. However, the relationship between visual estimates of CSF and quantitative wire-based invasive diagnosis of CMD is uncertain.
Methods: We prospectively enrolled adults aged ≥18 years with stable ischemic heart disease who were referred for invasive coronary angiography.

Objectives: Lack of evidence regarding safety and effectiveness at market entry is driving the need to consider adopting a lifecycle approach to evaluating medical devices, but it is unclear what lifecycle evaluation means. This research sought to explore the tacit meanings of "lifecycle" and "lifecycle evaluation" as embodied within evaluation models/frameworks used for medical devices.
Methods: Drawing on qualitative evidence synthesis methods and using an inductive approach, novel methods were developed to identify, appraise, analyze, and synthesize lifecycle evaluation models used for medical devices.
Background: The demand for orthopedic specialist consultations for patients with osteoarthritis in public hospitals is high and continues to grow. Lengthy waiting times are increasingly affecting patients from low socioeconomic and culturally and linguistically diverse backgrounds who are more likely to rely on public health care.
Objective: This study aimed to co-design a digital health intervention for patients with OA who are waiting for an orthopedic specialist consultation at a public health service, which is located in local government areas (LGAs) of identified social and economic disadvantage.

Acquired myasthenia gravis (MG) in dogs can present with focal or generalized weakness and is diagnosed by the presence of circulating antibodies to the acetylcholine receptor. Megaesophagus is the most common focal form of MG. Although exacerbation of MG has been associated with the use of fluoroquinolones in humans, it has not been previously described in dogs.

In this study we use human blood vessel organoids (BVOs) as a model of the microvasculature. BVOs fully recapitulate key features of the human microvasculature, including the reliance of mature endothelial cells on glycolytic metabolism, as concluded from metabolic flux assays and mass spectrometry-based metabolomics using stable tracing of C-glucose.
View Article and Find Full Text PDFDiabetic retinopathy (DR) is characterised by dysfunction of the retinal neurovascular unit, leading to visual impairment and blindness. Müller cells are key components of the retinal neurovascular unit and diabetes has a detrimental impact on these glial cells, triggering progressive neurovascular pathology of DR. Amongst many factors expressed by Müller cells, interleukin-33 (IL-33) has an established immunomodulatory role, and we investigated the role of endogenous IL-33 in DR.

Relapse during therapy with itraconazole and fluconazole has been reported. The aim of this study was to report the clinical response, duration of therapy, side effects, and outcome in cats with histoplasmosis that were treated with voriconazole.

Methods: We reviewed all Belgian healthcare payer (RIZIV-INAMI) assessor reports on novel implants or invasive medical devices (n = 18, Class IIb-III) available between 2018 to mid-2019 on applications submitted for inclusion on their reimbursement list. We also conducted a review of the literature on evidence gaps and an analysis of relevant legal and ethical frameworks within the European context.
Background: Management options for the treatment of melanoma have expanded in recent years. In an era of promising, but expensive novel pharmacological treatments, robust stage-specific melanoma-related cost estimates are necessary to support budgetary planning, evaluation of cost-effectiveness and to contribute to the investment case for prevention.
Methods: A detailed decision model, describing the melanoma care pathway (by disease stage) from diagnosis, through treatment and follow-up was developed over a 5-year time frame from the perspective of the Irish healthcare system.
BackgroundThe role of schools in SARS-CoV-2 transmission has been a debated topic since the beginning of the COVID-19 pandemic.AimTo examine SARS-CoV-2 transmission in all schools in Ireland during the 2020-21 school year.MethodsIn a national descriptive cross-sectional study, we investigated PCR-confirmed cases of COVID-19 among students (aged < 20 years) and staff (aged ≥ 20 years) who attended school during their infectious period to identify school close contacts.

The ongoing COVID-19 pandemic further increases these challenges. The use of remote models of care, including telemedicine, help to mitigate the impact of COVID-19 and provide new opportunities to engage existing and new patients in treatment.

Motivational interviewing is reported to be an effective psychological tool to produce a shift in one's behaviour resulting in improved outcomes. However, there is a lack of analyses investigating this tool's impact on healthy behaviours and health outcomes in cancer populations.

The purpose of this randomized, double-blinded, placebo-controlled study was to evaluate the effects of Fortetropin, a nonthermal-pasteurized, freeze-dried, fertilized egg yolk product, on mobility in senior dogs. Mobility scores were calculated using a standardized and validated client-based survey: the Liverpool Osteoarthritis in Dogs (LOAD) questionnaire.

There are no specific antiviral or immunomodulatory therapies recognized for treatment of CDV infections, and the neurological form typically carries with it a high mortality rate. The intrathecal injection of a modified live Newcastle disease virus vaccine (NDV-MLV) has been proposed for the treatment of the neurological forms of CDV infections.

Gadolinium-based contrast agents are used across species to better visualize abnormalities during MRI and are considered generally safe in clinical practice. The aim of this study was to investigate central nervous system (CNS) gadolinium deposition in 11 dogs that had an MRI performed, received 0.22 mL/kg (0.

Prescribing errors at discharge, including omission of pre-admission medications (PAM), are particularly harmful as they frequently propagate following discharge. This study assesses the impact of an educational intervention and introduction of an electronic patient record (EPR) in the same centre on omission of PAM at discharge using a pragmatic design.

Many researchers are explicitly adopting these principles to guide what, where, how and when research is undertaken with Indigenous people. With critical reflection to support the implementation of such principles largely absent from published literature, this paper explores both the implementation of, and the outcomes from a set of guiding principles used in a large-scale Australian research collaboration to improve Indigenous health.
