A wide range of comorbid diseases is associated with Alzheimer's disease (AD), the most common neurodegenerative disease worldwide. Evidence from clinical and molecular studies suggest that chronic diseases, including diabetes, cardiovascular disease, depression, and inflammatory bowel disease, may be associated with an increased risk of AD in different populations. Disruption in several shared biological pathways has been proposed as the underlying mechanism for the association between AD and these comorbidities. Notably, inflammation is a common dysregulated pathway shared by most of the comorbidities associated with AD. Some drugs commonly prescribed to patients with diabetes and cardiovascular disease have shown promising results in AD patients. Systems-based biology studies have identified common genetic factors and dysregulated pathways that may explain the relationship of comorbid disorders in AD. Nonetheless, the precise mechanisms for the occurrence of disease comorbidities in AD are not entirely understood. Here, we discuss the impact of the most common comorbidities in the clinical management of AD patients.

3D genomic features across >50 diverse cell types reveal insights into the genomic architecture of childhood obesity.

The prevalence of childhood obesity is increasing worldwide, along with the associated common comorbidities of type 2 diabetes and cardiovascular disease in later life. Motivated by evidence for a strong genetic component, our prior genome-wide association study (GWAS) efforts for childhood obesity revealed 19 independent signals for the trait; however, the mechanism of action of these loci remains to be elucidated. To molecularly characterize these childhood obesity loci, we sought to determine the underlying causal variants and the corresponding effector genes within diverse cellular contexts.

Objective: Oral health is often overlooked among the elderly due to the numerous comorbidities prevalent in this population. However, oral health significantly influences quality of life by affecting both general health and psychological well-being. The present study aimed to assess dental caries in elderly individuals using the DMFT index (decayed, missing, and filled teeth) and to explore its relationship with various factors based on data from the Azar cohort study in Iran.

Background: Rheumatoid arthritis (RA) is a degenerative autoimmune disease, often managed through symptomatic treatment. The co-occurrence of the reported extra-articular comorbidities such as inflammatory bowel disease (IBD), and dementia may complicate the pathology of the disease as well as the treatment strategies. Therefore, in our study, we aim to elucidate the key genes, and regulatory elements implicated in the progression and association of these diseases, thereby highlighting the linked potential therapeutic targets.

Department of Cardiovascular and Thoracic Surgery, Rush University Medical Center, Chicago, Illinois, USA.
Background: It has been proposed that more aggressive tumors trigger a stronger inflammatory response than less aggressive types. We hypothesize that systemic immune inflammatory index (SII) is associated with occult nodal disease (OND) in clinically node negative (cN0) patients undergoing lung resection for non-small cell lung cancer (NSCLC).
Study Design: The study included patients who underwent lung resection with nodal dissection, according to current guidelines, at a single center between 2010-2021 for NSCLC.
National survey of financial burden and experience among patients with cancer and autoimmune disease receiving charitable copay assistance.

Fox Chase Cancer Center, Temple University Health System, Philadelphia, Pennsylvania, USA.
Background: Little is known about the role that charitable copay assistance (CPA) plays in addressing access to care and financial distress. The study sought to evaluate financial distress and experience with CPA among patients with cancer and autoimmune disease.
Methods: This is a national cross-sectional self-administered anonymous electronic survey conducted among recipients of CPA to cover the costs of a drug for cancer or autoimmune disease.
