Background: Skin aging represents a significant public health burden globally, with Southeast Asian populations experiencing accelerated photoaging due to intensive environmental ultraviolet exposure. Aim: To evaluate the preventive efficacy of hydrolyzed collagen tonic drink on skin aging parameters in healthy Thai women. Methods: A double-blind, randomized controlled trial was conducted with 135 Thai women aged 40-60 years. Participants were randomized to receive either hydrolyzed fish collagen peptides with supportive nutrients (n=67) or active fruit juice control (n=68) daily for 12 weeks. Primary outcomes included skin microtopography parameters measured by Visioscan, skin elasticity assessed by Cutometer, and clinical photoaging classification using Glogau scale. Secondary outcomes examined molecular biomarker changes in procollagen Type I synthesis. Results: The collagen group demonstrated significantly attenuated skin surface deterioration compared to placebo. The Wrinkles parameter showed significant betweengroup differences at week 8 (-100.43 units, p=0.001). Smoothness parameter exhibited protective effects with significant between-group differences at week 8 (-80.08 units, p=0.002). Gross elasticity improved significantly within the collagen group at week 12 (p=0.033). Procollagen Type I synthesis demonstrated superior maintenance in the collagen group versus placebo (between-group percent change difference, p=0.002). Both groups achieved comparable Glogau classification improvements (23.9\% versus 20.6\%). Conclusion: Daily hydrolyzed collagen supplementation with supportive nutrients effectively prevented skin surface parameter deterioration in Thai women, demonstrating meaningful preservation of skin integrity through medium effect sizes for key parameters. These findings support nutritional approaches as complementary strategies for photoaging management in high ultraviolet-exposure populations

Background: Renal resistive index (RRI) and estimated glomerular filtration rate (eGFR) are predictive markers for chronic kidney disease (CKD) progression. Aim: To evaluate RRI value, eGFRcr-cys and renal biomarker in nondiabetic patients with CKD stage 3 in Bangkok, Thailand. Methods: A cross-sectional analytical analysis was conducted involving nondiabetic patients with CKD stage 3, aged 35-85 years. Ultrasound was used to assess the RRI of arteries in both kidneys. Patients underwent assessments of serum and urine 24-hour. Results: Among the 61 participants (67.2\% male; mean age 69.03 {\textpm} 12.59 years), the mean eGFRcr-cys was 41.63 {\textpm} 8.64 mL/min/1.73 m{\texttwosuperior}, and the mean RRI was 0.65 {\textpm} 0.06. Patients were categorized into three RRI groups: low (\<0.65, n=35), intermediate (0.65-0.70, n=14), and high (\>0.70, n=12). The high RRI group showed a mean RRI of 0.73 {\textpm} 0.05 (p \< 0.01). Among those with high RRI group were significant decreased right kidney size (p\<0.05) and they had a lower BMI, averaging 22.49 {\textpm} 3.48. An increase in PP (59.66 {\textpm} 13.84, p=0.04) was also significant in this group. The correlations coefficient of RRI value showed a significant positive correlation with age (p\<0.05) and significant negative with BMI (p\<0.05). In addition, eGFRcr-cys displayed a significant negative correlation with UAGT and 24hUP (p\<0.05) and a significant while eGFRcr-cys positive correlation with both kidney size and urine iNOS(p\<0.01). Conclusion: An increase in RRI is inversely linked to age, BMI, and PP. Lower eGFR is correlated with factors that cause CKD progression.

Background: Chronic kidney disease is a major public health issue, and due to resource constraints, many can{\textquoteright}t access dialysis. C. citratus, lemongrass is globally prevalent and known to increase urine output without toxicity. Objective: To examine the safety of C. citratus in patients with CKD stage 3. Materials and Methods: The major compound of C. citratus was analyzed using high-performance liquid chromatography (HPLC). 64 patients were enrolled and randomly assigned to control or C. citratus groups. The control group received a placebo, whereas the C. citratus group received 900 mg of C. citratus daily for 90 days. All participants were examined BUN, Scr, Cys-C, and eGFR, liver functions, RBC, HCT, Na+, K+, Cl-, and HCO3, and other biochemical parameters. Results: HPLC showed C. citratus contains of phenolic compounds. Clinically, C. citratus group had no notable side effects on T-Bil, AST, ALT and ALP. Also, maintained eGFR, SCys-C, K+ and Cl level. The level of blood Na+ was significant increase at day 30 (p \< 0.05). The control group had a significant decrease in eGFR and HCO3 levels (p \< 0.05) and a significant increase of Cl- and SCys-C. In addition, no statistical differences had found between groups in eGFR, BUN, Cr, Na+, K+, HCO3, PO4, RBC and HCT levels. Throughout the 90 days, no drug allergies or side effects were reported. Conclusion: Dietary supplementation with C. citratus may have a favorable effect on delaying the course of CKD and is safe to use for patients with CKD stage 3.
