Background: A nationwide Rehabilitation at Home Care Pilot Program for patients undergoing lower extremity orthopedic surgeries has been ongoing since 2020. The program was designed to improve clinical outcomes through early mobilization and rehabilitation after discharge. This study aimed to analyze the interim data to assess its effectiveness and suggest improvements, particularly for older patients who are more vulnerable compared to younger patients. Methods: We analyzed the data of 872 patients from seven hospitals. Patients were divided into an older-age group (OG; ≥60 years) and younger-age group (YG; <60 years). The Berg Balance Scale (BBS) and Numeric Rating Scale (NRS) scores for pain were the main outcomes. Results: Participants were categorized into OG (n=801) and YG (n=71). The most common surgeries were knee joint replacement (63.7%) in OG and hip joint replacement in YG (77.5%). It took more days to enroll in the pilot program in OG (4.4 days) than YG (3.2 days). OG showed less improvement in BBS than YG for all surgeries (23.3 vs. 31.9) and hip joint surgery (19.8 vs. 33.5). In patients with hip joint replacement in OG, those with a higher number of comorbidities (≥3) showed less BBS improvement than those with fewer comorbidities (<3). In the pain domain, NRS scores decreased in both groups. Conclusion The postoperative rehabilitation education program appeared to be effective in improving physical function and reducing pain severity, though the improvement was less obvious in older patients who may require a more comprehensive approach compared to younger patients.

Background: In Malaysia, occupational allergic contact dermatitis (ACD) is often under-reported. This case report describes a chemical engineer who developed possible ACD, likely due to workplace allergen exposure.Case presentation: He presented with a 4-month history of intensely itchy rashes on both hands, which improved during work breaks. A dermatological examination revealed lichenified, pruritic papules with well-defined borders on the palmar surfaces of both hands. A skin patch test identified reactions to five allergens, including ‘fragrance mix,’ ‘methyldibromo glutaronitrile,’ ‘clioquinol,’ ‘epoxy resin,’ and ‘textile dye mix.’ However, among these, only ‘bisphenol A diglycidyl ether,’ a component of ‘epoxy resin,’ was listed in the safety data sheet as a confirmed occupational exposure. In accordance with local regulations, this case was reported as ‘occupational dermatitis’ to the Department of Occupational Safety and Health. The patient was prescribed symptomatic topical treatments, including emollients and topical corticosteroids. Additionally, he was advised to switch to hypoallergenic products. On follow-up, his chronic inflammatory skin lesions showed improvement. Conclusions Thorough occupational history-taking and patch testing are essential for diagnosing ACD. Personalized health education and regular follow-ups, is crucial in monitoring lesion resolution and evaluating the effectiveness of preventive measures in workplace settings.

Purpose: There have been needs to improve the sensitivity of liquid biopsy. This report aims to report the analytical and clinical validation of a next-generation sequencing (NGS)–based circulating tumor DNA (ctDNA) assay. Materials and Methods: Analytical validation was conducted in vitro by evaluating the limit of detection (LOD), precision, and specificity for various genomic aberrations. The real-world performance in non–small cell lung cancer (NSCLC) was assessed by comparing the results of AlphaLiquid100 to the tissue-based results. Results: The LODs with 30 ng input DNA were 0.11%, 0.11%, 0.06%, 0.21%, and 2.13 copies for detecting single nucleotide variants, insertions, deletions, fusions, and copy number alterations (CNA), respectively. Quantitatively, single nucleotide variants/insertions and deletions, fusions, and CNAs showed a good correlation (R2=0.91, 0.40, and 0.65; y=0.95, 1.06, and 1.19) to the manufacturer’s values, and per-base specificities for all types of variants were near 100%. In real-world NSCLC (n=122), key actionable mutations in NSCLC were detected in 60.7% (74/122) with the ctDNA assay. Comparative analysis against the NGS-based tissue results for all key mutations showed positive percent agreement (PPA) of 85.3%. For individual genes, the PPA was as high as 95.7% for epidermal growth factor receptor (EGFR) mutations and 83.3% for ALK translocations. AlphaLiquid100 detected drug-sensitive EGFR mutation at a variant allele frequency as low as 0.02% and also identified an EGFR mutation in a case where tissue sample missed. Blood samples collected post-targeted therapies revealed additional acquired mutations. Conclusion The AlphaLiquid100 ctDNA assay demonstrates robust analytical validity, offering clinically important information for NSCLC patients.
