Health Utility Values Among Patients With Diabetic Retinopathy, Wet Age-Related Macular Degeneration, and Cataract in Thailand: A Multicenter Survey Using Time Trade-Off, EQ-5D-5L, and Health Utility Index 3.

Objectives: This study aimed to establish normative health utility data in Thai patients with diabetic retinopathy, wet age-related macular degeneration, and cataract; evaluate the sensitivity of different utility instruments to visual impairment; explore the relationship among these health utility values with the vision-specific quality of life (QoL); and assess the association of baseline characteristics and visual acuity level with health utility values and vision-specific QoL.

Methods: This multicenter cross-sectional survey included 309 patients from tertiary eye centers. We used health utility instruments (time trade-off [TTO], EuroQol five-dimension [EQ-5D-5L], and Health Utility Index 3 [HUI3]) and vision-specific QoL instrument (National Eye Institute Visual Function Questionnaire) for face-to-face interviews.

Two-tier architecture-based grading for pancreatic cancer outperforms traditional grading.

Objectives: A novel architecture-based grading system for pancreatic ductal adenocarcinoma (PDAC) is tested against traditional grading.

Methods: A total of 103 PDAC resections were graded by College of American Pathologists/American Joint Committee on Cancer (CAP/AJCC) guidelines and by a system using an architectural pattern (dispersed larger duct = low grade vs dense smaller duct = high grade). Survival analyses and interobserver variability were assessed.

Intraretinal hemorrhages and detailed retinal phenotype of three patients with Alagille syndrome.

Purpose: To explore patterns of disease expression in Alagille syndrome (ALGS).

Methods: Patients underwent ophthalmic examination, optical coherence tomography (OCT) imaging, fundus intravenous fluorescein angiography (IVFA), perimetry and full-field electroretinograms (ffERGs). An adult ALGS patient had multimodal imaging and specialized perimetry.

Platelet and INR Thresholds and Bleeding Risk in Ultrasound Guided Percutaneous Liver Biopsy: A Before-After Implementation of the 2019 Society of Interventional Radiology Guidelines Observational Quality Improvement Study.

To evaluate if implementation of the 2019 Society of Interventional Radiology (SIR) guidelines for periprocedural management of bleeding risk in patients undergoing percutaneous ultrasound guided liver biopsy is associated with increased haemorrhagic adverse events, change in pre-procedural blood product utilization, and evaluation of guideline compliance rate at a single academic institution. Ultrasound guided percutaneous liver biopsies from (January 2019-January 2023) were retrospectively reviewed (n = 504), comparing biopsies performed using the 2012 SIR pre-procedural coagulation guidelines (n = 266) to those after implementation of the 2019 SIR pre-procedural guidelines (n = 238). Demographic, preprocedural transfusion, laboratory, and clinical data were reviewed.

Frailty, Outcomes, Recovery and Care Steps of Critically Ill Patients (FORECAST): a prospective, multi-centre, cohort study.

Purpose: Frailty is common in critically ill patients but the timing and optimal method of frailty ascertainment, trajectory and relationship with care processes remain uncertain. We sought to elucidate the trajectory and care processes of frailty in critically ill patients as measured by the Clinical Frailty Scale (CFS) and Frailty Index (FI).

Methods: This is a multi-centre prospective cohort study enrolling patients ≥ 50 years old receiving life support > 24 h.

A Frailty Index to Predict Mortality, Resource Utilization and Costs in Patients Undergoing Coronary Artery Bypass Graft Surgery in Ontario.

Background: People living with frailty are vulnerable to poor outcomes and incur higher health care costs after coronary artery bypass graft (CABG) surgery. Frailty-defining instruments for population-level research in the CABG setting have not been established. The objectives of the study were to develop a preoperative frailty index for CABG (pFI-C) surgery using Ontario administrative data; assess pFI-C suitability in predicting clinical and economic outcomes; and compare pFI-C predictive capabilities with other indices.

Beyond Spirometry: Linking Wasted Ventilation to Exertional Dyspnea in the Initial Stages of COPD.

Exertional dyspnea, a key complaint of patients with chronic obstructive pulmonary disease (COPD), ultimately reflects an increased inspiratory neural drive to breathe. In non-hypoxemic patients with largely preserved lung mechanics - as those in the initial stages of the disease - the heightened inspiratory neural drive is strongly associated with an exaggerated ventilatory response to metabolic demand. Several lines of evidence indicate that the so-called excess ventilation (high ventilation-CO output relationship) primarily reflects poor gas exchange efficiency, namely increased physiological dead space.

Physiological Characterization of Preserved Ratio Impaired Spirometry in the CanCOLD Study: Implications for Exertional Dyspnea and Exercise Intolerance.

It is increasingly recognized that adults with preserved ratio impaired spirometry (PRISm) are prone to increased morbidity. However, the underlying pathophysiological mechanisms are unknown. Evaluate the mechanisms of increased dyspnea and reduced exercise capacity in PRISm.

Validation of Constant Work Rate Cycling Endurance Time for Use in Chronic Obstructive Pulmonary Disease Clinical Trials.

A COPD Foundation working group sought to identify measures of exercise endurance, a meaningful aspect of physical functioning in everyday life among patients with chronic obstructive pulmonary disease (COPD) that is not fully accepted in regulatory decision making, hampering drug development. To demonstrate, as we previously asserted (Casaburi 2022;9:252), that constant work rate cycling endurance time is an appropriate exercise endurance measure in patients with COPD. To validate this assertion, we assembled an integrated database of endurance time responses, including 8 bronchodilator (2,166 subjects) and 15 exercise training (3,488 subjects) studies (Casaburi 2022;9:520).

Intravenous albumin in cardiac and vascular surgery: a systematic review and meta-analysis.

Background: Intravenous albumin is commonly utilised in cardiovascular surgery for priming of the cardiopulmonary bypass circuit, volume replacement, or both, although the evidence to support this practice is uncertain. The aim was to compare i.v.

The Quality of Discharge Summaries After Acute Kidney Injury.

Background: Acute kidney injury (AKI) increases the risk of hospital readmission, chronic kidney disease, and death. Therefore, effective communication in discharge summaries is essential for safe transitions of care.

Objective: The objectives of this study were to determine the quality of discharge summaries in AKI survivors and identify predictors of higher quality discharge summaries.

Systemic Determinants of Exercise Intolerance in Patients With Fibrotic Interstitial Lung Disease and Severely Impaired D.

Background: The precise mechanisms driving poor exercise tolerance in patients with fibrotic interstitial lung diseases (fibrotic ILDs) showing a severe impairment in single-breath lung diffusing capacity for carbon monoxide (D < 40% predicted) are not fully understood. Rather than only reflecting impaired O transfer, a severely impaired D may signal deranged integrative physiologic adjustments to exercise that jointly increase the burden of exertional symptoms in fibrotic ILD.

Methods: Sixty-seven subjects (46 with idiopathic pulmonary fibrosis, 24 showing D < 40%) and 22 controls underwent pulmonary function tests and an incremental cardiopulmonary exercise test with serial measurements of operating lung volumes and 0-10 Borg dyspnea and leg discomfort scores.

Systematic review of simulation-based education in strabismus assessment and management.

Background: Strabismus is a dynamic condition for which simulation-based training is valuable, given the variable complexity and relatively reduced exposure compared with other ophthalmic presentations. This study assessed the performance of simulation models available for medical training in the assessment and management of strabismus.

Methods: A systematic review of relevant peer-reviewed academic databases was conducted, without publication date restrictions.

GWAS and meta-analysis identifies 49 genetic variants underlying critical COVID-19.

Critical illness in COVID-19 is an extreme and clinically homogeneous disease phenotype that we have previously shown to be highly efficient for discovery of genetic associations. Despite the advanced stage of illness at presentation, we have shown that host genetics in patients who are critically ill with COVID-19 can identify immunomodulatory therapies with strong beneficial effects in this group. Here we analyse 24,202 cases of COVID-19 with critical illness comprising a combination of microarray genotype and whole-genome sequencing data from cases of critical illness in the international GenOMICC (11,440 cases) study, combined with other studies recruiting hospitalized patients with a strong focus on severe and critical disease: ISARIC4C (676 cases) and the SCOURGE consortium (5,934 cases).
