BACKGROUND: Microplastics pose a significant environmental and health threat, yet the understanding and response of young adults to this issue remain underexplored. There is an increasing amount of microplastics in our environment and as the numbers grow, the danger that comes with it is still not fully understood. This study aimed to explore the knowledge, attitudes, and practices (KAP) of young adults in Muntinlupa, particularly students of a public university regarding microplastics and their health implications. METHODS: Employing a quantitative cross-sectional design, the research targeted college students aged 18 and older. RESULTS: Findings revealed that while students were knowledgeable about microplastics—particularly their harmful effects on health—attitudes and practices related to plastic disposal and recycling could be improved. Although the majority engaged in proper garbage disposal, only 41.5% consistently separated plastic waste from biodegradable materials. However, a weak positive correlation between knowledge and attitudes was observed, suggesting that increased awareness may enhance positive attitudes toward reducing microplastic pollution. CONCLUSION These results suggest that while students are aware of microplastics and generally responded positively, there remains a gap in the translation of knowledge into practices, highlighting the need for enhanced educational interventions.

The Discovery Elbow System (DES) utilizes a polyethylene bearing within the ulnar component. An exchange bearing requires preoperative freezing and implantation within 2 minutes of freezer removal to allow insertion. We report our outcomes and experience using this technique. Methods: This was an analysis of a two-surgeon consecutive series of DES bearing exchange. Inclusion criteria included patients in which exchange was attempted with a minimum 1-year follow-up. Clinical and radiographic review was performed 1, 2, 3, 5, 8 and 10 years postoperative. Outcome measures included range of movement, Oxford Elbow Score (OES), Mayo Elbow Performance Score (MEPS), complications and requirement for revision surgery. Results: Eleven DESs in 10 patients were included. Indications were bearing wear encountered during humeral component revision (n=5); bearing failure (n=4); and infection treated with debridement, antibiotics and implant retention (DAIR; n=2). Bearing exchange was conducted on the first attempt in 10 cases. One case required a second attempt. One patient developed infection postoperatively managed with two-stage revision. Mean follow-up of the bearing exchange DES was 3 years. No further surgery was required, with no infection recurrence in DAIR cases. Mean elbow flexion-extension and pronosupination arcs were 107° (±22°) and 140° (±26°). Mean OES was 36/48 (±12) and MEPS was 83/100 (±19). Conclusions: Our results support the use of DES bearing exchange in cases of bearing wear with well-fixed stems or acute infection. This series provides surgeons managing DES arthroplasty with management principles, successful and reproducible surgical techniques and expected clinical outcomes in performing DES polyethylene bearing exchange. Level of evidence: IV.
