Exploring transcriptomic and genomic latent variable correction approaches in differential expression analysis

Abstract Background Differential expression analysis is a central tool for studying the biological processes altered in human diseases via transcriptomic signatures. However, transcriptomic datasets are systematically confounded by latent variables from two distinct sources: unme...

Single-nucleus multi-omics reveals reversible molecular signatures in skeletal muscle of patients with heart failure with preserved ejection fraction

Heart failure with preserved ejection fraction (HFpEF) is a complex systemic syndrome characterized by severe exercise intolerance. In addition to cardiac dysfunction, abnormalities in peripheral skeletal muscle are key contributors to reduced exercise capacity in HFpEF. Multiple...

Neurologic Stability During Tafamidis Treatment in Transthyretin Amyloidosis with a Mixed Phenotype: A Multicenter Real-World Study

Real-world evidence on the effect of tafamidis in mixed-phenotype transthyretin (TTR) amyloidosis (ATTR amyloidosis) is limited. This study assessed changes in neurologic and other measures in patients with mixed-phenotype ATTR amyloidosis treated with tafamidis free acid 61 mg f...

Describing Patient Characteristics, Treatment Patterns, and Disease Burden Among Patients with Alopecia Areata in Mexico: A Secondary Analysis of the Adelphi Real World Alopecia Areata Disease Specific Programme

Alopecia areata (AA) is a common autoimmune disease characterized by nonscarring hair loss, yet real-world data on AA in Mexico are sparse. This study aimed to characterize disease burden and identify unmet treatment needs among patients with AA in Mexico. Clinical data were anal...

Invasive Pneumococcal Disease in Children: A Retrospective Three-Center Study in Zhejiang Province, China (2010–2024)

Invasive pneumococcal diseases (IPD) are among the leading causes of global child mortality. Pneumococcal conjugate vaccines provide direct protection against IPD caused by serotypes included in the vaccine. To investigate the clinical characteristics, serotypes, and antibiotic r...

Discovery of Neutral and Cerebrospinal Fluid Penetrant Transthyretin (TTR) Stabilizers with Heterocyclic Linkers

Abstract Human transthyretin (TTR) is associated with ATTR amyloidosis. Despite having approved agents against TTR, there is still an unmet medical need to develop novel agents, especially those that could have therapeutic effects in cerebrospinal fluid (CSF). Structure-based dru...

Use of telehealth and at-home video for remote administration of the North Star Ambulatory Assessment (NSAA): a comparative methods study

Remote functional assessments can expand access and reduce burden for families affected by Duchenne muscular dystrophy (DMD), but evidence is needed on the reliability of remote administration and scoring of the North Star Ambulatory Assessment (NSAA). We conducted a non-interven...

Assessing residual bias in real-world vaccine effectiveness studies: validating negative controls to avoid misleading results

Observational studies and randomized controlled trials demonstrate that vaccines protect against infections and severe outcomes, but real-world vaccine effectiveness estimates remain vulnerable to residual biases. Negative control outcomes can help detect and mitigate such biases...

Healthcare providers’ perceptions and prescribing behaviors of short-term prevention treatment of migraine in the United States

AIMS: Short-term prevention (STP) therapies are used to prevent migraine during anticipated exposure to known triggers. However, little is known about healthcare providers' (HCPs) attitudes and prescribing practices regarding STP. This study aimed to characterize real-world STP t...

A collaborative study evaluating the detection of virus-infected cells by transcriptomic high-throughput sequencing

High-throughput sequencing (HTS) is an agnostic virus detection technology that can replace or supplement the conventional adventitious virus assays used for safety testing of biologics. Transcriptomic HTS is particularly suitable for the detection of replicating viruses. We have...

Summary of Research: HER2CLIMB-05: A Phase III Study of Tucatinib Versus Placebo in Combination with Trastuzumab and Pertuzumab as First-Line Maintenance Therapy for HER2+ Metastatic Breast Cancer

This is a summary of a research article reporting the findings of the HER2CLIMB-05 trial (NCT05132582), a randomized, double-blind, placebo-controlled, international, phase III trial. The HER2CLIMB-05 trial was conducted to compare the efficacy and safety of adding tucatinib vers...

Bivalent RSVpreF Effectiveness Against Respiratory Syncytial Virus (RSV)-Related Respiratory Disease Hospitalization and Emergency Department Visits Across Three RSV Seasons

Respiratory syncytial virus (RSV) protein subunit vaccines reduce the risk of severe outcomes such as hospitalization and emergency department (ED) visits for at least two RSV seasons following vaccination. No data have been published on real-world RSV vaccine effectiveness (VE)...

Quantitative analysis of artificial intelligence–based detection of subregions from murine ear skin sections with application to quantifying drug-induced epidermal hyperplasia

The advent of artificial intelligence (AI) technologies is creating a paradigm shift in drug discovery and development. Veterinary pathology is an area that can significantly benefit from AI tools. The availability of AI algorithms in commercial software packages such as HALO and...

Sex Differences in a Contemporary, Real-World Cohort of Patients with Transthyretin Amyloid Cardiomyopathy Treated with Tafamidis

INTRODUCTION: Tafamidis improves outcomes in patients with transthyretin amyloid cardiomyopathy (ATTR-CM) versus placebo. ATTR-CM has historically been considered a predominantly male disease, and women are underrepresented in prior studies. Sex-specific data in contemporary pati...

The SISAQOL-IMI glossary: harmonising terminology for patient-reported outcomes in cancer clinical trials
