ABSTRACT
Marine biofouling poses significant challenges to maritime industries worldwide, affecting vessel performance, fuel efficiency, and environmental sustainability. These challenges demand innovative and sustainable solutions. In this review, the evolving landscape of cellulose-based materials for anti-fouling applications in marine environments is explored. Through a comprehensive bibliometric analysis, the current state of research is examined, highlighting key trends, emerging technologies, and geographical distributions. Cellulose, derived from renewable resources, offers a promising avenue for sustainable anti-fouling strategies due to its biodegradability, low toxicity, and resistance to microbial attachment. Recent advancements in cellulose-based membranes, coatings, and composites are discussed, showcasing their efficacy in mitigating biofouling while minimizing environmental impact. Opportunities for interdisciplinary collaboration and innovation are identified to drive the development of next-generation anti-fouling solutions. By harnessing the power of cellulose, progress towards cleaner, more sustainable oceans can be facilitated, fostering marine ecosystems and supporting global maritime industries.
ABSTRACT
BACKGROUND: type 2 diabetes mellitus (T2DM) and gastroesophageal reflux disease (GERD) are commonly seen in the geriatric population. This study aimed to investigate the prevalence, risk factors, and alarm-symptoms incidence of GERD among elderly patients with T2DM in a rural area of Central Sulawesi. METHODS: this cross-sectional study was conducted from July-September 2019 in Public Health Center of Beteleme, Central Sulawesi. Patients aged ≥60 years old, newly or previously diagnosed with T2DM according to the 2019 American Diabetes Association (ADA) criteria or to the 2015 Indonesian Society of Endocrinology (PERKENI) criteria, were consecutively recruited. We excluded patients being on proton-pump inhibitor or H2-receptor antagonist therapy or having a history of gastric or esophageal surgery. GERD was diagnosed in patients with the score of ≥8 based on the Indonesian version of GERD questionnaire (GERD-Q). RESULTS: among 60 elders with T2DM, 28.3% (95% confidence interval [CI], 16.9-39.7) had GERD. Statistical analysis showed that GERD was significantly associated with consumption frequency of tea (p=0.019) and coffee (p=0.015). No significant relationship was found between gender (p=0.562), obesity (p=0.803), achievement of blood glucose-level control (p=0.478), duration of T2DM (p=0.304), and type of antihyperglycemic drugs (p=0.202) with GERD. Unintentional weight loss was the leading alarm symptom (47.1%; 95%CI, 23.4%-70.8%) found across the GERD group. CONCLUSION: GERD was prevalent among elderly patients with diabetes. Frequent consumption of either tea or coffee was associated with GERD. Alarm symptoms need further evaluation to screen for complications.
