The noninvasive ventilation outcomes score in patients requiring NIV for COPD exacerbation without prior evidence of airflow obstruction

Introduction

Exacerbation of COPD complicated by respiratory acidaemia is the commonest indication for noninvasive ventilation (NIV). The NIV outcomes (NIVO) score offers the best estimate of survival for those ventilated. Unfortunately, two-thirds of cases of COPD are unrecognised, and patients may present without COPD having been confirmed by spirometry.

Methods

In the 10-centre NIVO validation study there was no pre-admission spirometry in 111 of 844 consecutive patients (termed "clinical diagnosis" patients). We compared the performance of the NIVO, DECAF and CURB-65 scores for in-hospital mortality in the clinical diagnosis cohort. Usual clinical practice was not influenced, but confirmation of COPD in the year following discharge was captured.

Results

In the clinical diagnosis cohort, in-hospital mortality was 19.8% and rose incrementally across the NIVO risk categories, consistent with the NIVO validation cohort. NIVO showed good discrimination in the clinical diagnosis cohort: area under the receiver operating curve 0.724, versus 0.79 in the NIVO validation cohort. At 1 year after discharge, 41 of 89 clinical diagnosis patients had undertaken diagnostic spirometry; 33 of 41 had confirmation of airflow obstruction (forced expiratory volume in 1 s/(forced) vital capacity <0.7), meaning the diagnosis of COPD was incorrect in 19.5% of cases.

Discussion

These data support the use of the NIVO score in patients with a "clinical diagnosis" of COPD. NIVO can help guide shared decision-making, assess risk-adjusted outcomes by centre and challenge prognostic pessimism. Accurate diagnosis is critical to ensure that acute and long-term treatment is optimised; this study highlights failings in the follow-up of such patients.

Intra-Aneurysmal High-Resolution 4D MR Flow Imaging for Hemodynamic Imaging Markers in Intracranial Aneurysm Instability [RESEARCH]

BACKGROUND AND PURPOSE:

Prediction of aneurysm instability is crucial to guide treatment decisions and to select appropriate patients with unruptured intracranial aneurysms (IAs) for preventive treatment. High-resolution 4D MR flow imaging and 3D quantification of aneurysm morphology could offer insights and new imaging markers for aneurysm instability. In this cross-sectional study, we aim to identify 4D MR flow imaging markers for aneurysm instability by relating hemodynamics in the aneurysm sac to 3D morphologic proxy parameters for aneurysm instability.

MATERIALS AND METHODS:

In 35 patients with 37 unruptured IAs, a 3T MRA and a 7T 4D MRI flow scan were performed. Five hemodynamic parameters—peak-systolic wall shear stress (WSSMAX) and time-averaged wall shear stress (WSSMEAN), oscillatory shear index (OSI), mean velocity, and velocity pulsatility index—were correlated to 6 3D morphology proxy parameters of aneurysm instability—major axis length, volume, surface area (all 3 size parameters), flatness, shape index, and curvedness—by Pearson correlation with 95% CI. Scatterplots of hemodynamic parameters that correlated with IA size (major axis length) were created.

RESULTS:

WSSMAX and WSSMEAN correlated negatively with all 3 size parameters (strongest for WSSMEAN with volume (r = –0.70, 95% CI –0.83 to –0.49) and OSI positively (strongest with major axis length [r = 0.87, 95% CI 0.76–0.93]). WSSMAX and WSSMEAN correlated positively with shape index (r = 0.61, 95% CI 0.36–0.78 and r = 0.49, 95% CI 0.20–0.70, respectively) and OSI negatively (r = –0.82, 95% CI –0.9 to –0.68). WSSMEAN and mean velocity correlated negatively with flatness (r = –0.35, 95% CI –0.61 to –0.029 and r = –0.33, 95% CI –0.59 to 0.007, respectively) and OSI positively (r = 0.54, 95% CI 0.26–0.74). Velocity pulsatility index did not show any statistically relevant correlation.

CONCLUSIONS:

Out of the 5 included hemodynamic parameters, WSSMAX, WSSMEAN, and OSI showed the strongest correlation with morphologic 3D proxy parameters of aneurysm instability. Future studies should assess these promising new imaging marker parameters for predicting aneurysm instability in longitudinal cohorts of patients with IA.

27 Warm & Fuzzy Fall Feline Funnies Overflowing With Autumnal Affection for Snuggling Sweetly in Soft Sweaters

Good meowrning, feline fanatics, and happy Tuesday. A lot of people rant and rave over summer, but us? We love fall and winter. Why? Because it's sweater weather. We love sweaters. We love wearing sweaters, putting sweaters on our cats, snuggling in sweaters, sleeping in sweaters, heck, we would even exercise in sweaters if we could. There is nothing comfier than putting on a fuzzy sweater and burrowing your way under the blanket for ultimate comfort. 

These warm and fuzzy feline funnies are basically cat memes wrapped in soft sweaters. They're full of autumnal affection, heartwarming vibes, and they're purrfect for enjoying when you need to feel extra cozy (and, purrhaps, silly). We thought to ourselves, "how can one improve the purrfection that is cat memes?" - and the answer was simple: add the feeling of throwing on a sweater to them. So that we did. Grab your favorite sweater (cardigans and sweatshirts are also okay) and get ready for a catastrophe of comfort in the form of cat memes. You will be comfy, there is no escaping it.
