Objectives: There remain hesitations and miscommunication regarding appropriate public health behaviours and conceptions related to COVID-19. We tested the effectiveness of the community-based health cell approach in improving knowledge, attitude and practice (KAP) related to COVID-19.
Setting: Households of the Bauniabadh slum area in Mirpur, Dhaka, Bangladesh.
Participants: Household heads (HHs) and homemakers (HMs) of intervention (n=211) and comparison households (n=209).
Interventions: Behaviour change communication delivered at the community level in a quasi-experimental manner through small-scale community meetings and home visits.
Outcome Variables And Methods: The outcomes of interest were before-after mean and per cent changes in KAP scores. Data were collected from HHs and HMs before and after the intervention and difference-in-differences (DID) analysis technique was applied.
Results: We found statistically significant (p<0.05) before-after differences in the responses to the KAP questions made by the intervention groups. The DID models estimated the improvements in COVID-19-related KAP of HHs by 16.58 (95% CI: 14.05, 19.12), 20.92 (95% CI: 18.17, 23.67) and 28.45 (95% CI: 23.84, 33.07) per cent points, respectively. The DID estimates of KAP in HMs were 17.8 (95% CI: 15.09, 20.51), 22.33 (95% CI: 19.47, 25.19) and 28.06 (95% CI: 23.18, 32.93) per cent points, respectively. Overall, 20.91 (95% CI: 18.87, 22.94) and 21.81 (95% CI: 19.68, 23.94) per cent points of improvement were observed among HHs and HMs, respectively. The DID estimates of before-after mean changes in different KAP domains ranged from 2.24 to 2.68 units and the overall changes in KAP scores among HHs and HMs were 7.11 (95% CI: 6.42, 7.8) and 7.42 (95% CI: 6.69, 8.14) units.
Conclusion: Scientifically valid information disseminated at the community level using the health cell approach could bring positive changes in KAP related to COVID-19.

Aluminum is a well-known and widely distributed environmental neurotoxin. This study aimed to investigate the effect of miR-98-5p targeting insulin-like growth factor 2 (IGF2) on aluminum neurotoxicity. Thirty-two Sprague-Dawley rats were randomly divided into four groups and administered 0, 10, 20, and 40 μmol/kg maltol aluminum [Al(mal)], respectively.

This study aimed to identify differentially expressed non-coding RNAs (ncRNAs) associated with preterm birth (PTB) and determine biological pathways being influenced in the context of PTB. We processed cell-free RNA sequencing data and identified seventeen differentially expressed (DE) ncRNAs that could be involved in the onset of PTB. Per the validation via customized RT-qPCR, the recorded variations in expressions of eleven ncRNAs were concordant with the analyses.

Antimicrobial drug resistance is a significant global health challenge, causing hundreds of thousands of deaths annually and severely impacting healthcare systems worldwide. Several reported antimicrobial compounds have a guanidine motif, as the positive charge on guanidine promotes cell lysis. Therefore, pyrrole- and indole-based allylidene hydrazine carboximidamide derivatives with guanidine motifs are proposed as antimicrobial agents that mimic cationic antimicrobial peptides (CAMPs).

Importance: Cell and gene therapies are revolutionizing the treatment landscape for children and adults with rare diseases and can be life-changing for patients and their families. Successful implementation of these new therapies into clinical practice depends on their accessibility and affordability, particularly through publicly funded Medicaid agencies, which cover many children and adults with rare diseases.
Objective: To provide a framework to broadly assess cell and gene therapies, evaluate payment options, and ensure equitable access through the lens of publicly funded Medicaid programs.
Aqueous Leaf Extract of Protects Against Gentamicin-Induced Kidney Injury via Decreases in Renal Function, Inflammation, and Apoptosis Markers.

The effect of the aqueous extract of (AAI) on gentamicin (GEN)-induced kidney injury was investigated. The study involves 20 adult male Wistar rats (housed in four separate plastic cages) such that graded dosages of AAI were administered to the experimental group for 14 days per oral (PO) before exposure to GEN toxicity (100 mg/kg) for 1 week. At the end of the study, comparisons of some markers of renal functions, antioxidant status, and inflammatory and apoptotic markers were made between the control, GEN, and AAI-pretreated groups at < .
