Cellular senescence regulates aging, tissue maintenance, and disease progression through the Senescence-Associated Secretory Phenotype (SASP), a secretory profile of cytokines, chemokines, growth factors, and matrix-remodeling enzymes. While transient SASP aids wound healing, its chronic activation drives inflammation, fibrosis, and tumorigenesis. This review examines SASP’s molecular regulation, dual roles in health and pathology, and therapeutic potential. The following two main strategies are explored: senescence clearance, which eliminates SASP-producing cells, and SASP modulation, which refines secretion to suppress inflammation while maintaining regenerative effects. Key pathways, including NF-κB, C/EBPβ, and cGAS-STING, are discussed alongside pharmacological, immunotherapeutic, gene-editing, and epigenetic interventions. SASP heterogeneity necessitates tissue-specific biomarkers for personalized therapies. Challenges include immune interactions, long-term safety, and ethical considerations. SASP modulation emerges as a promising strategy for aging, oncology, and tissue repair, with future advancements relying on multi-omics and AI-driven insights to optimize clinical outcomes.

Diabetes mellitus is a major public health issue that considerably impacts mortality, morbidity, and healthcare costs worldwide. The COVID-19 pandemic has created havoc in diabetes management, too, like other spectrums of life. A descriptive, cross-sectional study was adopted to determine the effect of Social Support, Self-Care Behaviour and Self-Efficacy in Type 2 Diabetes Mellitus (T2D) during this COVID-19 pandemic. Two hundred T2D patients who satisfied the inclusion criteria were chosen using a convenient sampling procedure. The tool consists of four sections, including socio-demographic characteristics, Multidimensional Scale of Perceived Social Support (MSPSS), revised Summary of Diabetes Self-Care Activities (SDSCA) Scale and modified Diabetes Management Self-Efficacy Scale (DMS). Descriptive and inferential statistics were used to analyze the obtained data. The mean and SD of diabetic management self-efficacy is 5.74 (1.95) and 4.37 (1.4), respectively, for patients with HbA1c < 6.5% and HbA1c ≥ 6.5%. The self-care activities of the patients who had good glycemic control were 4.31 (2.06) compared to 3.50 (1.73) who did not. The social support received by the patients was 6.13 (2.13) vs. 5.31 (1.67) among patients with glycemic control vs. no control. The results show that social support (p = 0.04), self-efficacy (p =0.01) and self-care activities (p = 0.001) were significantly related to the level of glycemic control of the T2D patients. A significant relationship was also identified between gender (p = 0.036), age (p = 0.001) and education status (p = 0.000) with HbA1c control of the participants. This study demonstrates a significant relationship between social support, self-care behaviours, self-efficacy and glycemic management in T2D patients. During this COVID-19 pandemic, interventions to enhance the self-care activities like exercise and social support to boost their self-efficacy; for better diabetes management, reducing diabetes complications or prolonging their onset are the need of the hour.

The study sought to identify parental trends in children's self-medication, health-seeking behavior, knowledge of self-medication, antibiotic use, and antimicrobial resistance in Asir, Saudi Arabia. A web-based cross-sectional study was carried out by a survey questionnaire. Snow Ball sampling technique was used to select the Eight hundred and sixteen parents with children in the Asir region by WhatsApp and email, and 650 participants who met the inclusion criteria consented to participate in the study. There were 1809 episodes of childhood illnesses reported during the study period. The mean scores are on knowledge at 8.11 ± 2.43, favorable attitude at 17.60 ± 1.17, and practice was 7.72 ± 1.72, and a significant correlation was found between knowledge, attitude, and practice (KAP) at p = 0.01. Out of 624, the majority of parents showed strong knowledge and proficiency in antibiotics. However, the attitude scores of over 50% towards the usage of antibiotics were subpar. Around 54% of parents were self-medicating their children and 43% were unaware that skipping doses contributes to anti-microbial resistance (AMR). The facilitators for self-medication were male gender (aOR: 2.13; 95% CI: 1.26-3.98, p < 0.05), having more children (aOR: 2.78; 95% CI: 1.27-4.12 p < 0.01), professional qualification (aOR:3.07; 95% CI 1.57- 4.68; p < 0.01), residing in urban area (aOR: 3.17; 95% CI: 2.13-5.61, p < 0.05), working in health care (aOR: 5.99; 95% CI: 1.78-18.2, p < 0.01) and high income (aOR: 3.57; 95% CI: 2.08-6.34, p < 0.05). The findings indicated that the majority of parents had unfavorable views and improper practices of antibiotic usage. Strategic education programs to the targeted population, especially to the parents about side effects of antibiotics, dangerous consequences of self-medication, and crucial AMR concerns must be addressed immediately.

Pharmacogenomics is revolutionizing precision medicine by enabling tailored therapeutic strategies based on an individual genetic and molecular profile. Circular RNAs (circRNAs), a distinct subclass of endogenous non-coding RNAs, have recently emerged as key regulators of drug resistance, tumor progression, and therapeutic responses. Their covalently closed circular structure provides exceptional stability and resistance to exonuclease degradation, positioning them as reliable biomarkers and novel therapeutic targets in cancer management. This review provides a comprehensive analysis of the interplay between circRNAs and pharmacogenomics, focusing on their role in modulating drug metabolism, therapeutic efficacy, and toxicity profiles. We examine how circRNA-mediated regulatory networks influence chemotherapy resistance, alter targeted therapy responses, and impact immunotherapy outcomes. Additionally, we discuss emerging experimental tools and bioinformatics techniques for studying circRNAs, including multi-omics integration, machine learning-driven biomarker discovery, and high-throughput sequencing technologies. Beyond their diagnostic potential, circRNAs are being actively explored as therapeutic agents and drug delivery vehicles. Recent advancements in circRNA-based vaccines, engineered CAR-T cells, and synthetic circRNA therapeutics highlight their transformative potential in oncology. Furthermore, we address the challenges of standardization, reproducibility, and clinical translation, emphasizing the need for rigorous biomarker validation and regulatory frameworks to facilitate their integration into clinical practice. By incorporating circRNA profiling into pharmacogenomic strategies, this review underscores a paradigm shift toward highly personalized cancer therapies. circRNAs hold immense potential to overcome drug resistance, enhance treatment efficacy, and optimize patient outcomes, marking a significant advancement in precision oncology.

Background: Pharmacists and other healthcare professionals (HCPs) are at risk of transmitting the lethal COVID-19 virus globally and increasing its prevalence. Aim: The aim of this study was to assess knowledge, attitudes, and practices (KAP) about coronavirus disease 2019 (COVID-19) among HCPs in the Asir region for the first time. Methodology: A cross-sectional analysis with 491 healthcare professionals was tested using a pre-tested questionnaire in a tertiary care facility. The association between research variables and questions was determined using Chi-square tests and Kruskal–Wallis tests. Results: Pharmacists and other HCPs exhibited good knowledge, a positive attitude, and a negative practice pattern regarding COVID-19. There was a strong association between knowledge and attitude (correlation coefficient: 0.17; p < 0.001). However, healthcare practitioners had a suboptimal practice score of 2.09 ± 0.62 regarding COVID-19. Conclusion: This study discovered that despite relatively insufficient practices for adherence to recommended techniques regarding COVID-19 prevention during the outbreak, pharmacists and other healthcare professionals have a high level of awareness and a positive attitude towards COVID-19 as a medical condition. There is a need for more involved HCPs, improved COVID-19 management training, and approaches to make healthcare providers feel less anxious.

Background/Objectives: Gouty arthritis (GA) is a chronic inflammatory condition characterized by hyperuricemia and NLRP3 inflammasome activation, leading to joint damage and systemic inflammation. Although allopurinol (ALP), a xanthine oxidase inhibitor, effectively lowers serum urate levels, it has limited anti-inflammatory effects. This study investigated whether combining disulfiram (DSF), a known NLRP3 inflammasome inhibitor, with ALP enhances therapeutic outcomes in a rat model of gout. Methods: Thirty male Albino Wistar rats (150–200 g) were randomly assigned to five groups (n = 6): control, disease control, ALP-treated, DSF-treated, and ALP + DSF combination. Hyperuricemia was induced using potassium oxonate, followed by MSU crystal injection to trigger acute gout. Treatment lasted 30 days. Efficacy was assessed through clinical scoring, paw swelling, serum uric acid levels, ELISA-based cytokine profiling (IL-1β, TNF-α, IL-6), renal function tests, radiography, and histopathology. Results: Combination therapy with ALP + DSF significantly reduced paw swelling (p < 0.05), inflammation index (p < 0.001), serum uric acid (p < 0.001), and pro-inflammatory cytokines compared to monotherapy. Histopathology revealed preserved synovial architecture and reduced inflammatory infiltration. Radiographic imaging showed attenuated soft tissue swelling and joint erosion. Renal function markers were also improved in the combination group. Conclusions: The combination of ALP and DSF provided superior anti-inflammatory and urate-lowering effects compared to individual treatments. These findings support the potential of disulfiram as an adjunct to conventional ULTs in gout management through dual modulation of urate metabolism and inflammasome-driven inflammation.
