Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease characterized by an unpredictable decline in lung function. Predicting IPF progression from the early changes in lung function tests have known to be a challenge due to acute exacerbation. Although it is unpredictable, the neighboring regions of fibrotic reticulation increase during IPF's progression. With this clinical information, quantitative characteristics of high-resolution computed tomography (HRCT) and a statistical learning paradigm, the aim is to build a model to predict IPF progression. A paired set of anonymized 193 HRCT images from IPF subjects with 6-12month intervals were collected retrospectively. The study was conducted in two parts (1) Part A collects the ground truth in small regions of interest (ROIs) with labels of "expected to progress" or "expected to be stable" at baseline HRCT and develop a statistical learning model to classify voxels in the ROIs. (2) Part B uses the voxel-level classifier from Part A to produce whole-lung level scores of a single-scan total probability's (STP) baseline. Using annotated ROIs from 71 subjects' HRCT scans in Part A, we applied Quantum Particle Swarm Optimization-Random Forest (QPSO-RF) to build the classifier. Then, 122 subjects' HRCT scans were used to test the prediction. Using Spearman rank correlations and survival analyses, we ascertained STP associations with 6-12month changes in quantitative lung fibrosis and forced vital capacity. This study can serve as a reference for collecting ground truth, and developing statistical learning techniques to predict progression in medical imaging.

The ideal duration of dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) is still unknown. In this meta-analysis, we aimed to compare very short-term (1-3months), short-term (6months), standard-term (12months) and long-term (>12months) DAPT durations for efficacy and safety. Overall DAPT comparisons were classified as "any shorter-term"/"any longer-term" DAPT. https://www.selleckchem.com/products/gw6471.html The primary outcome was a composite of major adverse cardiovascular events (MACE non-fatal myocardial infarction, non-fatal stroke and cardiovascular death). The primary safety outcome was major bleeding. Twenty-six studies comprising 103.394 patients were included. Compared with standard-term DAPT duration, very short-term DAPT duration with subsequent drop of aspirin (RR 1.06, 95% CI, 0.95-1.18, p=0.26) or drop of the P2Y inhibitor (RR 0.92, 95% CI, 0.72-1.16, p = 0.47) was not associated with a higher risk of MACE. Any longer-term compared with any shorter-term DAPT durations led to a significantly lower risk of MACE (RR 0.88, 95% CI, 0.81-0.96, p=0.002), but a significantly higher risk of BARC 3-5 major bleeding events (RR 1.63, 95% CI, 1.22-2.17, p=0.001). In the ACS subgroup receiving prasugrel or ticagrelor but not clopidogrel, any longer-term DAPT duration was associated with a significantly lower risk of MACE compared to any shorter-term DAPT duration (RR 0.84, 95% CI, 0.77-0.92, p=0.0001). DAPT may be shortened to 1-3months in patients with low ischemic but high bleeding risk followed by aspirin or P2Y monotherapy. Prasugrel or ticagrelor based DAPT may be extended to >12months in case of high ischemic and low bleeding risk. CRD42020163719.

For cardiac related disorders, such as atherosclerosis, hypertension, and myocardial infarction, designer micro or nanoparticles are often administered into the vasculature or targeted vessel with the hope to circumvent problems associated with conventional drug delivery, including negative systemic side effects. Additionally, novel nano-drug carriers that enter circulation can be selectively uptaken by immune cells with the intended purpose that they modulate inflammatory processes and migrate locally to plaque for therapeutic payload delivery. Indeed, innovative design in nanoparticle composition, formulation, and functionalization has advanced the field as a means to achieve therapeutic efficacy for a variety of cardiac disease indications. This perspective aims to discuss these advances and provide new interpretations of how nanotechnology can be best applied to aid in cardiovascular disease treatment. In an effort to spark discussions on where the field of research should go, we share our outlook in new areas of nanotechnological inclusion and integration, such as in vascular, implantable, or wearable device technologies as well as nanocomposites and nanocoatings. Further, as cardiovascular diseases (CVD) increasingly claim a number of lives globally, we propose more attention should be placed by researchers on nanotechnological approaches for risk factor treatment to aid in early prevention and treatment of CVD.Acute respiratory distress syndrome (ARDS) is a devastating pulmonary disease with significant in-hospital mortality and is the leading cause of death in COVID-19 patients. Excessive leukocyte recruitment, unregulated inflammation, and resultant fibrosis contribute to poor ARDS outcomes. Nanoparticle technology with cerium oxide nanoparticles (CNP) offers a mechanism by which unstable therapeutics such as the anti-inflammatory microRNA-146a can be locally delivered to the injured lung without systemic uptake. In this study, we evaluated the potential of the radical scavenging CNP conjugated to microRNA-146a (termed CNP-miR146a) in preventing acute lung injury (ALI) following exposure to bleomycin. We have found that intratracheal delivery of CNP-miR146a increases pulmonary levels of miR146a without systemic increases, and prevents ALI by altering leukocyte recruitment, reducing inflammation and oxidative stress, and decreasing collagen deposition, ultimately improving pulmonary biomechanics.Anti-cancer strategies using nanocarrier systems have been explored in a variety of cancers; these systems can easily be incorporated into tumors via the enhanced permeability and retention (EPR) effect leading to enhanced anti-tumor activity while reducing systemic toxicity by specific tumor-targeting. The prognosis of hepatocellular carcinoma (HCC) is extremely poor when the condition is diagnosed at the unresectable stage as treatment options are limited. In order to improve the treatment of cancer and the overall anti-cancer effect, polymerized phenylboronic acid conjugated doxorubicin (pPBA-Dox) nanocomplexes were generated, and conjugated doxorubicin, which is conventionally used in HCC. The nanocomplexes exhibited enhanced anti-tumor activity via tumor-specific targeting in the subcutaneous and orthotopic HCC syngeneic mice tumor model, implying that the nanocomplexes facilitate the targeted Dox delivery to liver cancer in which the sialic acid is over-expressed. Therefore, this study provides insight into the novel targeted therapy using the nanocomplexes for the treatment of HCC.
