Introduction: Adequate knowledge of diabetes is essential for effective self-management and glycemic control. Emerging trends in digital platforms, video-based education offer a scalable and accessible approach to patient learning. However, evidence on the effectiveness of validated YouTube-based diabetes education in the Malaysian population remains limited. We aimed to evaluate the impact of a newly developed, tri-language YouTube diabetes education programme on clinical and knowledge outcomes. Methodology: In this multicentre study, patients with diabetes mellitus were randomly assigned to intervention (YouTube-based education) and control groups (standard care). The intervention consisted of newly developed and validated short educational videos on YouTube regarding diabetes, complications and lifestyle changes, delivered weekly via WhatsApp over 9 weeks. Videos were available in English, Malay and Chinese. The control group received standard care and counseling. Demographic data, hemoglobin A1c (HbA1c), and knowledge scores were collected at baseline and 3 months post-intervention. Results: A total of 109 patients (62.4% female; mean age 53.2 years; mean diabetes duration 16.3 years) were enrolled in the study, with similar baseline characteristics between groups. The intervention group demonstrated significantly greater improvement in glycemic control compared to the control group (HbA1c: −1.22 ± 1.36% vs. −0.24 ± 1.05%; p <0.001). While knowledge scores improved in both groups, the increase was significantly greater in the intervention group (2.66 vs. 0.80; p = 0.001). Notably, improvement in knowledge score predicted HbA1c reduction (b = 0.091; 95% CI 0.01, 0.172; p = 0.028). Conclusion The tri-language YouTube-based diabetes education programme significantly improved both glycemic control and patients’ knowledge. This accessible, scalable video-based education represents an effective strategy to enhance diabetes selfmanagement, offering flexible, on-demand learning for diverse populations.

Objective:To compare the differences in specimen results between the intelligent robotic phlebotomy group and the manual venipuncture group, and to evaluate the clinical applicability of the autonomous blood collection system.Methods:From January 20 to October 28, 2022, 154 volunteers at Zhongshan Hospital, Fudan University underwent paired blood collections (robotic and manual) within 5 minutes. The collected samples were analyzed for: hemolysis index (HI), alanine transaminase (ALT), aspartate transaminase (AST), L-γ-glutamyltransferase (γ-GT), lactate dehydrogenase (LDH), urea nitrogen (UREA), creatinine (CRE), uric acid (UA), glucose (GLU), total cholesterol (TC), triglyceride (TG), natrium (Na), kalium (K), chlorine (Cl), creatine kinase (CK), CK-MB, CK-MM, and neuron-specific enolase (NSE). Statistical analyses used t-tests and Wilcoxon signed-rank tests.Results:The results of two different blood collection methods revealed that the HI values of 154 specimens in the intelligent robot blood collection group were all less than 20SI, while 7 specimens (4.54%) in the manual blood collection group had HI values exceeding 20SI; In the comparison of 17 biochemical and immunological markers, there were statistically significant differences between groups in 8 items including γ-GT[20.00(15.00, 37.75)U/L vs. 19.00 (14.00, 36.25)U/L, Z=2.497, P<0.05], LDH[165.5 (147.0, 183.0)U/L vs. 173.0 (155.0, 193.0)U/L, Z=8.629, P<0.05], TC[(5.002±0.856)mmol/L vs.(5.031±0.870) mmol/L, t=-3.006, P<0.05], K[4.1 (4.0, 4.3)mmol/L vs. 4.3 (4.1, 4.4)mmol/L, Z=5.592, P<0.05], CK[97.00 (73.00, 133.00)U/L vs. 99.00 (74.75, 136.25)U/L, Z=3.490, P<0.05], CK-MB[13 (11, 15)U/L vs. 14 (12, 16)U/L, Z=6.581, P<0.05], CK-MM[84.00 (60.00, 119.00)U/L vs. 83.50 (58.75, 118.00)U/L, Z=3.790, P<0.05], and NSE[10.600 (9.500, 11.700)ng/ml vs. 11.950 (10.475, 13.725)ng/ml, Z=8.151, P<0.05]. Conclusions:In the collection of serum samples, intelligent blood collection robots can achieve standardization and normalization of specimen collection volume and mixing in the pre-analysis stage. The hemolysis related indicators of the collected specimens are lower than those of the manual collection group, and can be used for the collection of clinical serological specimens.

Objective:To investigate the clinicopathological characteristics and molecular variants of chromophobe renal cell carcinoma with small cell components/neuroendocrine-like features (ChRCC-SC/ND-L).Methods:There were 7 cases of ChRCC-SC/ND-L diagnosed by light microscopy and immunohistochemical staining were collected from the Affiliated Hospital of Qingdao University (5 cases) and 971 Hospital of the People′s Liberation Army Navy (2 cases) between January 2010 and December 2023. The clinical data, histological characteristics, and immunohistochemical staining results of the patients were summarized. Among them, 4 cases underwent whole exome sequencing.Results:Among the 7 cases, 5 cases were male and 2 cases were female. The mean age was 53 (43,58)years,with a range of 36 to 76 years. Gross examination showed that the mean maximum tumor diameter was 7.9 (6.0,9.0) cm,with a range of 5.5 to 13.0 cm. The tumors were nodular, well-defined, gray, red or yellow in color with a solid cut surface, except for 1 case with cystic and solid on cut surface. One case showed visible necrosis, and 1 case invaded the renal pelvis and sinus. Microscopically, the tumors had clear boundaries. Typical ChRCC components (5 cases of classical type, 2 cases of eosinophilic type) were found in all cases, accompanied by varying amounts of small cell components (5%-90%). The two components were mixed in 6 cases or directly adjacent to each other in 1 case. The small cell components were arranged in clusters, dense acinar and nest-like structures, beam-like, fence-like, chrysanthemum-shaped clusters, and ribbon-like patterns. Three cases exhibited patchy necrosis. Intravascular tumor thrombus was found in 1 case. Immunohistochemically, EMA was expressed consistently in the small cell and typical ChRCC components (7/7); whilst both CK7 and CD117 were negative in 1 case with typical ChRCC component (6/7). Small cell components in 3 cases were positive for CD56, whereas all 7 cases were negative for CgA, Syn, and INSM1. The Ki-67 proliferation index was less than 1% in both components. Whole exome sequencing revealed that the 4 cases exhibited different genetic aberrations including 1 case with multiple chromosomal deletions, while 2 cases showed amplification of chromosome 12 and deletion of chromosome 11, respectively. The 7 cases were followed up for 25 to 172 months. Except for 1 patient that died with unknown causes 25 months after surgery, the remaining 6 cases were still alive (average 103.8 months, median 101 months).Conclusions:ChRCC-SC/ND-L is a very rare subtype of ChRCC. The small cell component does not represent true neuroendocrine differentiation and might indicate a morphological heterogeneity of the tumor. The presence of typical chromophobe cell carcinoma components is helpful for the diagnosis of ChRCC-SC/ND-L and they do not have consistent molecular characteristics. ChRCC-SC/ND-L has a good prognosis and the small cell components/neuroendocrine-like components might not have a significant impact on the outcome of patients with the tumor.

INTRODUCTION: Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration. METHOD: An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded. RESULTS: The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations. CONCLUSION The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.

Alzheimer's disease (AD), a prototypical neurodegenerative disorder, encompasses multifaceted pathological processes. As pivotal cellular structures within the central nervous system, ion channels play critical roles in regulating neuronal excitability, synaptic transmission, and neurotransmitter release. Extensive research has revealed significant alterations in the expression and function of ion channels in AD, implicating an important role of ion channels in the pathogenesis of abnormal Aβ deposition, neuroinflammation, oxidative stress, and disruptions in calcium homeostasis and neural network functionality. This review systematically summarizes the crucial roles and underlying mechanisms of ion channels in the onset and progression of AD, highlighting how these channel abnormalities contribute to AD pathophysiology. We also discuss the therapeutic potential of ion channel modulation in AD treatment, emphasizing the importance of addressing multifactorial nature and heterogeneity of AD. The development of multi-target drugs and precision therapies is proposed as a future direction of scientific research.

Objective To improve the underwater technique during the start phase of breaststroke swimmers through swimming flume training and assess its effectiveness in enhancing competitive performance.Methods The participants were 14 male swimmers in the short-distance Level 4 category from the Shanghai Swimming Team,and they were randomly divided into the experimental group(n=7)and control group(n=7).The experimental group underwent swimming flume start training,while the control group underwent regular pool start training,and both groups received the training twice a week for 16 weeks.Before and after the 16-week training,a 15-m breaststroke start test was conducted.Repeated measures analysis of variance and paired t-tests were used to compare the changes in kinematic parameters(time,speed,and entry angle)between and within groups.Results After 16 weeks of specialized training,the 15-m performance at the start for the experimental group and control group(F(1,12)=6.52,P＜0.05,η2=0.39)showed an interaction,with the experimental group performing better after training compared to the control group before training(P＜0.05).In the experimental group,the duration of the pull-out phase(F(1,12)=10.28,P＜0.01,η2=0.46)and the second sliding phase(F(1,12)=4.81,P＜0.05,η2=0.22)was improved;the distance of the pull-out phase(F(1,12)=4.71,P＜0.05,η2=0.21)and the second sliding phase(F(1,12)=4.90,P＜0.05,η2=0.21)was improved;the speed of the pull-out phase(F(1,12)=4.77,P＜0.05,72=0.20)was significantl improved.The within-group statistics showed that the experimental group significantly improved their exit speed(P＜0.05).The hand entry angle was optimized(P＜0.05),while changes in other joint angles were not significant.Conclusions Swimming flume training reduced the time spent in the pull-out and second gliding phases during the breaststroke start,effectively preventing the speed loss during underwater gliding.This provides an experimental evidence for enhancing start performance and optimizing training method for breaststroke swimmers.

Objective To investigate the mechanisms by which astaxanthin(AST)alleviates oxaliplatin(OXA)-induced neuropathic pain through antioxidant pathways so as to provide theoretical basis for clinical intervention.Methods Animal experiments:SD rats were divided into five groups(n=6):control group,OXA(4 mg/kg)group,OXA+Oil group,OXA+AST(5 mg/kg)group,and OXA+AST(10 mg/kg)group.Mechanical and cold pain thresholds were measured at day 0,7,14,and 21.Malondialdehyde(MDA)content and superoxide dismutase(SOD)activity in the dorsal root ganglia(DRG)were detected using the thiobarbituric acid(TBA)method and WST-1 assay,respectively.Western blotting was performed to analyze the expressions of Nrf2 and HO-1.Cell experiments:neuro-2a cells were divided into control group,OXA(50 μmol/L)group,AST(10 μmol/L)group,and OXA(50 μmol/L)+AST(10 μmol/L)group.Cells were treated with nerve growth factor(NGF,50 ng/mL)to induce growth,and morphological changes were observed under an inverted microscope.Intracellular reactive oxygen species(ROS)level and mitochondrial superoxide were measured using DCFH-DA fluorescent probe and MitoSOXTM red,respectively.Mitochondrial function was assessed by JC-1 assay.Western blotting was used to detect Nrf2 and HO-1 expressions.Results Animal experiments:① Mechanical and cold pain thresholds were reduced in OXA and OXA+Oil groups(P＜0.05),while AST significantly increased these thresholds in OXA-treated rats(P＜0.05).② SOD activity decreased while MDA content increased in the DRG of OXA-treated rats(P＜0.05).AST restored SOD activity and reduced MDA level(P＜0.05,P＜0.01).③ Western blotting showed elevated Nrf2 and HO-1 expressions in OXA group(P＞0.05),which were further upregulated by AST(P＜0.05,P＜0.01).Cell experiments:① OXA reduced the number of neurite-bearing cells and shortened the average neurite length(P＜0.05).Inverted microscopic observation revealed that AST intervention increased both parameters(P＜0.01,P＜0.001).② OXA increased intracellular and mitochondrial ROS fluorescence intensity(P＜0.05),which was attenuated by AST(P＜0.01).③ JC-1 assay revealed decreased mitochondrial membrane potential in OXA group(P＜0.01),which was partially reversed by AST(P＜0.05).④ Western blotting results showed that OXA upregulated Nrf2 and HO-1 expressions(P＜0.05,P＜0.01),and AST further enhanced their levels(P＜0.01).Conclusion AST alleviates OXA-induced neuropathic pain by promoting Nrf2/HO-1 expression,enhancing SOD activity,reducing lipid peroxidation and ROS production,and improving mitochondrial function.

Objective To analyze the clinical characteristics of renal cell carcinoma patients with extracapsular segmental vein tumor thrombus during partial nephrectomy and to explore the clinical significance,thereby contributing to an advanced comprehension of the pathogenesis of cancer thrombus in renal cell carcinoma.Methods A retrospective analysis was conducted on the clinical data of 209 renal cell carcinoma patients(162 with T1a stage,47 with T1b stage)who underwent partial nephrectomy in our hospital during Sep.2023 and Jul.2025.Among them,8 patients with extracapsular segmental vein tumor thrombus were identified,and the clinical and pathological characteristics were analyzed.Results Among the 8 cases of extracapsular segmental vein tumor thrombus,1 was in T1a stage and 7 were in T1b stage.Preoperativc CT revealed roundish,solid renal masses with heterogeneous density on non-contrast scans,significant enhancement on contrast-enhanced scans,and markedly weaker enhancement in the renal parenchymal phase compared to normal renal tissue.The average tumor diameter was(4.9±0.2)cm,with clear boundaries and no evidence of vascular invasion.Postoperative pathology confirmed clear cell carcinoma in all cases,with International Society of Urological Pathology(ISUP)grades ranging from Ⅰ to Ⅳ,and all surgical margins were negative.After surgery,5 patients received adjuvant immunotherapy.In a median follow-up of 10.3(3.8-22.8)months,no tumor recurrence or metastasis was observed.Conclusion Renal cell carcinoma has a high propensity of vascular invasion,and even clinically staged T1 tumors may develop extracapsular segmental vein tumor thrombus.This finding is significant for clinical prognosis.
