Abstract: Hypertension prevalence in the Special Region of Yogyakarta (31.8%) is higher than the national average (30.8%), and long-term medication use may create a burden that negatively affects adherence. This study aimed to evaluate the relationship between medication-related burden and adherence among hypertensive outpatients at Panembahan Senopati Bantul Regional Hospital and Yogyakarta City Regional Hospital. Using a cross-sectional design, 161 patients were recruited between January and February 2025. Medication-related burden was assessed with the Living with Medicines Questionnaire version 3 (LMQ-3), while adherence was measured using the Medication Adherence Rating Scale-5 (MARS-5). Most patients experienced a low burden (76.4%), followed by no burden (15.5%) and moderate burden (8.1%). Regarding adherence, 83.2% showed moderate adherence and 16.8% high adherence. Spearman’s correlation analysis revealed a significant negative relationship between medication-related burden and adherence (p=0.000; Rho = -0.461). These findings suggest that a higher treatment burden reduces adherence to antihypertensive therapy, highlighting the need for strategies to minimize patient burden and improve treatment outcomes.

Abstract: Background, anaphylactic shock (AS) caused by iodinated contrast media (ICM) is a rare but potentially life-threatening immediate hypersensitivity reaction. Despite widespread use of ICM in diagnostic imaging, data on ICM-related AS are limited, particularly in Indonesia. Early recognition and timely intervention are crucial to reduce morbidity and mortality. Case presentation, a 28-year-old female underwent renal arteriography with iodixanol. Within 5 minutes of contrast administration, she developed a generalized pruritic rash, dyspnea, vomiting, hypotension, and unstable cardiac parameters. Clinical presentation confirmed iodixanol-induced anaphylactic shock. Management, initial management included intramuscular epinephrine, rapid intravenous fluids, intravenous antihistamines and corticosteroids, and norepinephrine infusion. The patient’s hemodynamic status stabilized, and she was monitored in the CVCU for 48 hours. Outcome and conclusion, the patient recovered fully without complications. This case emphasizes the importance of rapid recognition and prompt pharmacologic intervention in ICM-induced anaphylaxis, while highlighting the value of thorough allergy documentation and preventive counseling.

Abstract: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) represent critical events in disease progression, yet their complex pathophysiology remains incompletely understood. Understanding the mechanisms underlying these exacerbations is essential for developing effective therapeutic strategies and improving patient outcomes. This literature review aims to synthesize current knowledge on the cellular and molecular mechanisms driving acute exacerbations of COPD, highlighting the importance of utilizing appropriate animal models for future research. This review identified rodent models, particularly mice (C57BL/6 strain) and rats (Sprague-Dawley) are predominantly employed due to their genetic tractability and physiological relevance, with occasional use of guinea pigs for airway hyperresponsiveness studies. Combined approaches using cigarette smoke exposure followed by inflammatory triggers (LPS, viral infections) showed the highest translational relevance. Key pathophysiological mechanisms studied include neutrophilic inflammation, oxidative stress, airway remodelling, and mucus hypersecretion. Current animal models provide valuable insight into AECOPD pathophysiology but face limitations in fully recapitulating human disease complexity. Future directions should focus on incorporating comorbidities, aging, and standardized outcome measures. Show less...

Abstract: Conventional vaccines face challenges in antigen stability, delivery efficiency, and scalability, particularly in low- and middle-income countries. Nanochemistry offers innovative approaches through lipid nanoparticles, polymeric carriers, and hybrid systems. This review evaluates these platforms using criteria such as physicochemical properties, immunological outcomes, translational feasibility, and One Health relevance. A narrative literature review was conducted across major databases between 2015 and 2025. Studies were screened by title and abstract, excluded if not directly relevant to vaccine delivery, and weighted according to design, with clinical trials prioritized over in vitro or modeling studies. Reference lists of key papers were also examined to ensure comprehensive coverage. Lipid nanoparticles supported mRNA delivery in licensed COVID-19 vaccines, achieving strong immune responses but with variability across populations and reported adverse events including myocarditis and anaphylaxis. Polymeric nanoparticles such as PLGA and chitosan enabled controlled antigen release, though cost-effectiveness remains constrained by manufacturing and scalability challenges. Hybrid lipid-polymer systems demonstrated enhanced stability and multi-antigen presentation, with current evidence largely limited to preclinical studies. One Health implications are defined as the potential of nanochemistry to contribute to zoonotic disease prevention, food safety, and cross-species vaccine design, requiring clearer frameworks for integration. In conclusion, nanochemistry-based vaccine platforms show promise for advancing immunization strategies, but unresolved issues in safety evaluation, regulatory harmonization, and equitable access highlight the need for cautious interpretation and further interdisciplinary collaboration.
