Dementia and vision impairment (VI) are common among older adults but little is known about caregiving in this context.

We used data from the 2011 National Health and Aging Trends Study, a nationally representative survey of Medicare beneficiaries, linked to their family/unpaid helpers from the National Study of Caregiving. Vision impairment was defined as self-reported blindness or difficulty with distance/near vision. Probable dementia was based on survey report, interviews, and cognitive tests. Our outcomes included hours of care provided, and number of valued activities (scored 0-4) affected by caregiving, per month.

Among 1,776 caregivers, 898 (55.1%, weighted) assisted older adults without dementia or VI, 450 (21.9%) with dementia only, 224 (13.0%) with VI only, and 204 (10.0%) with dementia and VI. In fully adjusted negative binomial regression analyses, caregivers of individuals with dementia and VI spent 1.7 times as many hours (95% confidence interval [CI] = 1.4-2.2) providing care than caregivers of those without either impairment; however, caregivers of individuals with dementia only (95% CI = 1.1-1.6) and VI only (95% CI = 1.1-1.6) spent 1.3 times more hours. Additionally, caregivers of individuals with dementia and VI had 3.2 times as many valued activities affected (95% CI = 2.2-4.6), while caregivers of dementia only and VI only reported 1.9 times (95% CI = 1.4-2.6) and 1.3 times (95% CI = 0.9-1.8) more activities affected, respectively.

Our results suggest that caring for older adults with VI involves similar time demands as caring for older adults with dementia, but that participation impacts are greater when caring for older adults with both dementia and VI.

Given the worldwide spread of the novel Severe Acute Respiratory Syndrome Coronavirus 2 (nSARS-CoV-2) infection pandemic situation, research to repurpose drugs, identify novel drug targets, vaccine candidates have created a new race to curb the disease. While the molecular signature of nSARS-CoV-2 is still under investigation, growing literature shows similarity among nSARS-CoV-2, pulmonary edema, and thromboembolic disorders due to common symptomatic features. A network medicine approach is used to to explore the molecular complexity of the disease and to uncover common molecular trajectories of edema and thrombosis with nSARS-CoV-2.

A comprehensive nSARS-CoV-2 responsive miRNA Transcription Factor (TF) gene co-regulatory network was built using host-responsive miRNAs and it's associated tripartite, Feed-Forward Loops (FFLs) regulatory circuits were identified. These regulatory circuits regulate signaling pathways like virus endocytosis, viral replication, inflammatory response, pulmonary vascularization, cell cycle control, virus spike protein stabilization, antigen presentation, etc. A unique miRNA-gene regulatory circuit containing a consortium of four hub FFL motifs is proposed to regulate the virus-endocytosis and antigen-presentation signaling pathways. selleck products These regulatory circuits also suggest potential correlations/similarity in the molecular mechanisms during nSARS-CoV-2 infection, pulmonary diseases and thromboembolic disorders and thus could pave way for repurposing of drugs. Some important miRNAs and genes have also been proposed as potential candidate markers. A detailed molecular snapshot of TGF signaling as the common pathway, that could play an important role in controlling common pathophysiologies among diseases, is also put forth.

The discovery of miRNAs has greatly expanded our understanding of the intricate scenario of genome-wide regulation. Over the last two decades, hundreds of virus-encoded miRNAs have been identified, most of which are from DNA viruses. Although the number of reported RNA virus-derived miRNAs is increasing, current knowledge of their roles in physiological and pathological processes has remained lacking. In this review, we discuss the biogenesis and biological functions of RNA virus- encoded miRNAs and their proposed roles in virus-host interactions and further underscore their potential value in the diagnosis and treatment of viral diseases.
MicroRNAs play key roles in host-pathogen-interactions and disease pathogenesis. Our aim was to characterize the differentially expressed miRNAs in the blood cells of diseased (Brucellosis-positive, Johne's disease-positive) and healthy- water buffaloes. The pooled small-RNA samples of each group were sequenced on Ion Torrent Personal Genome Machine (PGM) sequencer and the data were analyzed for differential expression.

Here we identified 274 known miRNAs with bovine homologs and 36 novel mature-star miRNAs from the sequnces of small RNA libraries. Overall 195 miRNAs were common to all the three groups. Certain miRNAs such as bta-miR-21-5p, -26a, -29a/b, -30d - 103, - 140, - 150, - 191, - 374, - 1434-5p,-1260b, - 2484 and let-7 members were abundantly expressed in diseased groups. Bta-miR-1434-5p, - 188, -200c were up-regulated (> 1.5 folds) while bta-miR-27a-5p, -34b and -2285x were down-regulated (> 100 folds) in Brucellosis group. In Johne's Disease group, only 3 miRNAs (bta-miR-1434-5p, - 2340 and - 2484) were up-regulated (> 1.5 folds). The functional classification of miRNA target genes into gene ontology (GO) terms indicated their involvement in innate immunity and cellular process of disease pathogenesis. Expression profile of four differentially expressed miRNAs (bta-miR-9-5p, - 677, - 331-3p and - 2440) and eight predicted target-genes were validated through reverse transcriptase qPCR.

This study provides a valuable frame of reference for elucidation of regulatory roles of miRNAs associated with disease pathogenesis in water buffaloes as well as identification of miRNA biomarkers for disease diagnosis and treatment.
