Nanocarrier imaging at single-cell resolution across entire mouse bodies with deep learning.

Efficient and accurate nanocarrier development for targeted drug delivery is hindered by a lack of methods to analyze its cell-level biodistribution across whole organisms. Here we present Single Cell Precision Nanocarrier Identification (SCP-Nano), an integrated experimental and deep learning pipeline to comprehensively quantify the targeting of nanocarriers throughout the whole mouse body at single-cell resolution. SCP-Nano reveals the tissue distribution patterns of lipid nanoparticles (LNPs) after different injection routes at doses as low as 0.

Lipoprotein(a), high-sensitivity c-reactive protein, homocysteine and cardiovascular disease in the Multi-Ethnic Study of Atherosclerosis.

Background And Aims: Elevated lipoprotein(a) [Lp(a)], high-sensitivity C-Reactive Protein (hs-CRP), and total homocysteine (tHcy) are associated with atherosclerotic cardiovascular disease (ASCVD) risk. This study investigated the individual and joint associations of Lp(a), hs-CRP and tHcy with coronary heart disease (CHD) and stroke.

Methods: This study was conducted in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort (2000-2017) (CHD analytic = 6,676; stroke analytic = 6,674 men and women).

Association of Lipoprotein(a) With Major Adverse Cardiovascular Events Across hs-CRP: A Systematic Review and Meta-Analysis.

Background: Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease. The relationship between Lp(a) and major adverse cardiovascular events (MACE) in the context of high-sensitivity C-reactive protein (hs-CRP) levels remains controversial due to conflicting results from previous studies.

Objectives: This systematic review and meta-analysis aimed to clarify the association between Lp(a) and risk of MACE across different hs-CRP levels in both primary and secondary prevention settings.

Cardiac Magnetic Resonance Imaging Findings in COVID-19: Experience from a Tertiary Care Center of North India.

Purpose: Here, we describe cardiac magnetic resonance imaging (CMR) findings in patients with proven COVID-19 infection and presenting with cardiac problems both at presentation and in convalescence from a tertiary care center, in North India. A pertinent review of the literature is also discussed.

Materials And Methods: Retrospective analysis of patients with real-time reverse transcriptase-polymerase chain reaction proven COVID-19 infection either at presentation or convalescence referred for CMR at our facility from January 2021 to December 2023 was done.

Persistence of spike protein at the skull-meninges-brain axis may contribute to the neurological sequelae of COVID-19.

SARS-CoV-2 infection is associated with long-lasting neurological symptoms, although the underlying mechanisms remain unclear. Using optical clearing and imaging, we observed the accumulation of SARS-CoV-2 spike protein in the skull-meninges-brain axis of human COVID-19 patients, persisting long after viral clearance. Further, biomarkers of neurodegeneration were elevated in the cerebrospinal fluid from long COVID patients, and proteomic analysis of human skull, meninges, and brain samples revealed dysregulated inflammatory pathways and neurodegeneration-associated changes.

Traditional Risk Factors, Optimal Cardiovascular Health, and Elevated Lipoprotein(a).

Aims: To assess the association of traditional risk factor burden and Life's Simple 7 (LS7) score with incident atherosclerotic cardiovascular disease (ASCVD) across Lp(a) levels.

Methods: There were 6,676 participants without clinical ASCVD from the Multi-Ethnic Study of Atherosclerosis who underwent Lp(a) testing and were followed for incident ASCVD events (coronary heart disease and stroke). Low, intermediate, and elevated Lp(a) were defined as <30, 30-49, and >50 mg/dL, respectively.

Oxidized Phospholipids and Calcific Aortic Valvular Disease.

Background: Oxidized phospholipids (OxPLs) are carried by apolipoprotein B-100-containing lipoproteins (OxPL-apoB) including lipoprotein(a) (Lp[a]). Both OxPL-apoB and Lp(a) have been associated with calcific aortic valve disease (CAVD).

Objectives: This study aimed to evaluate the associations between OxPL-apoB, Lp(a) and the prevalence, incidence, and progression of CAVD.

Representation of women and racial minorities in SGLT2 inhibitors and heart failure clinical trials.

Background: Inadequate representation of women and racial minorities in heart failure (HF) clinical trials continues to limit the generalizability of the results. This could create a disparity in treatment for future heart failure therapies and devices. The study aims to assess the representation of women and racial minorities in recent heart failure studies involving sodium-glucose cotransporter-2 (SGLT-2) inhibitors.

Independence of Lipoprotein(a) and Low-Density Lipoprotein Cholesterol-Mediated Cardiovascular Risk: A Participant-Level Meta-Analysis.

Background: Low-density lipoprotein cholesterol (LDL-C) and lipoprotein(a) (Lp[a]) levels are independently associated with atherosclerotic cardiovascular disease (ASCVD). However, the relationship between Lp(a) level, LDL-C level, and ASCVD risk at different thresholds is not well defined.

Methods: A participant-level meta-analysis of 27 658 participants enrolled in 6 placebo-controlled statin trials was performed to assess the association of LDL-C and Lp(a) levels with risk of fatal or nonfatal coronary heart disease events, stroke, or any coronary or carotid revascularization (ASCVD).

Tracking Wall Characteristics of Necrotic Pancreatic Fluid Collections in Acute Pancreatitis on Serial Contrast-Enhanced Computed Tomography.

 Encapsulated pancreatic fluid collection (PFC) is a requisite for endoscopic drainage procedures. The 4-week threshold for defining walled-off necrosis does not capture the dynamic process of encapsulation. We aim to investigate the changes in the wall characteristics of PFC in acute necrotizing pancreatitis (ANP) by comparing baseline contrast-enhanced computed tomography (CECT) with follow-up CT scans.

Body mass index and cognitive functioning decline: Exploring the relationship.

Background: Cognitive functions may play an important role in the management of obesity by promoting compliance towards lifestyle-related behaviours. This study aimed to identify cognitive deficits among adults and examine their association across different Body Mass Index (BMI) categories in an Indian setting.

Materials And Methods: The study is a cross-sectional survey of a sample attending a tertiary care hospital in northern India.

C-H amination chemistry mediated by trinuclear Cu(I) sites supported by a ligand scaffold featuring an arene platform and tetramethylguanidinyl residues.

Tripodal ligands that can encapsulate single or multiple metal sites in -symmetric geometric configurations constitute valuable targets for novel catalysts. Of particular interest in ligand development are efforts toward incorporating apical elements that exhibit little if any electron donicity, to enhance the electrophilic nature of a positioned active oxidant (, metal-oxo, -nitrene). The tripodal ligand TMGtrphen-Arene has been synthesized, featuring an arene platform 1,3,5-substituted with phenylene arms possessing tetramethylguanidinyl (TMG) residues.

Strategies for management of patients with elevated lipoprotein(a).

Purpose Of Review: There is growing literature that supports the testing of Lp(a). However, few patients are tested, including those with a personal or family history of cardiovascular disease (CVD). One often noted barrier to more widespread testing is uncertainty regarding what to do with an elevated Lp(a) level.

Chest CT Findings at Six Months Following COVID-19 ARDS - Correlation With the mMRC Dyspnea Scale and Pulmonary Function Tests.

Many survivors of severe COVID-19 pneumonia experience lingering respiratory issues. There is limited research on follow-up chest imaging findings in patients with COVID-19 ARDS, particularly in relation to their mMRC dyspnea scores and pulmonary function tests (PFTs). This study addresses this gap by investigating the clinical characteristics, mMRC dyspnea scores, PFTs, and chest CT findings of COVID-19 ARDS patients at the 6 months post-recovery.
