IntroductionThis study aims to determine the clinical outcomes of a new technique of cartilage repair surgery, using calcified cartilage zone debridement coupled with Hyalofast and bone marrow aspirate concentrate, in terms of pain and functional outcomes.
MethodsThis was a retrospective case series in 19 patients with cartilage injuries, ICRS 3 and 4. Using arthroscopic examination, cartilage defects were identified and debrided. Then, the calcified cartilage zone was identified and scrapped, until punctate bleeding occurred. Hyalofast was fixed into the defect and bone marrow aspirate concentrate was injected into the Hyalofast. Patients were followed up at baseline, 1, 6, and 18 months post-operative, using visual analog scale, KOOS, IKDC, and Lysholm Score.
ResultsThe mean age was 45.33 ± 9.68 years, with the mean cartilage defects of 10.21 ± 11.10 X 9.43 ± 10.85 mm2. Among the cohort, seven patients (36.8%) underwent three chondral repair procedures, five (26.4%) received two procedures, and the remaining seven (36.8%) were treated with a single procedure. In the KOOS subscale, there was a steady improvement; symptoms (mean difference: −23.87, CI: −43.97 – −3.77, p-value = 0.015), pain (mean difference: −28.39, CI: −43.94 – −12.83, p-value = 0.001), activity of daily living (mean difference: −26.23, CI: −40.95 – −10.14, p-value = 0.001), and sports subscale (mean difference: −57.36, CI: −80.76 – −33.97, p-value Conclusion
The calcified cartilage zone debridement technique served as a novel technique to preserve subchondral plate allowing better outcomes for cartilage repair.
Knee osteoarthritis (OA) is a serious public health problem since it is linked to loss of muscular function and independence, especially in older adults. In this study, the researchers have proposed a randomised controlled trial with a three-arm study strategy to explore the effectiveness of an oral nutritional supplementation containing hydroxymethylbutyrate and undenatured type-II collagen combined with exercise training (ET) on the OA-related symptoms and biomarkers among adults with knee OA.
Adults with knee OA aged between 50 years and 75 years will be invited to participate in the study and thereafter will be randomly assigned to either one of three groups: oral nutrition supplementation+ET, ET or usual care. The primary outcomes include changes in OA-related symptoms and biomarkers. The secondary outcomes include changes in body composition, blood profiles, physical fitness, quality of life, dietary intake, disability, psychology status and morphological changes of the knee.
Ethics approval was granted by the Medical Research Ethics Committee of the National University of Malaysia (reference number JEP-2024–264). Findings of this study will be disseminated via peer-reviewed presentations at scientific conferences as well as open access publications.
Environmental tobacco smoke (ETS) is generally known as secondhand smoke. Assessing the magnitude of children’s exposure to ETS from early infancy is essential for public health and research endeavours. Urinary cotinine is now widely recognised as the primary indicator for assessing exposure to ETS across all age groups. This systematic review and meta-analysis aim to synthesise all the published evidence on the urinary cotinine cut-off concentrations used to categorise children under 5 years as being exposed to ETS.
We will conduct a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A comprehensive search will be conducted from various databases including PubMed, EMBASE, Scopus and Cochrane Library. This search will be performed from the earliest published articles up to the latest available studies until February 2025. We will include all the experimental and observational studies, such as cohort, case–control and cross-sectional, that measure urinary cotinine concentrations in children under 5 years old. Data extraction will be conducted using a standardised data extraction form, and the study quality will be evaluated according to the guidelines specified by the Newcastle-Ottawa Scale. The extracted data will be pooled and combined for meta-analysis. Two reviewers will independently screen, select and assess the quality of the included study. The result will be tabulated in a table of characteristics of the included study, which consists of the cut-off cotinine concentrations, analytical technique, method referred, study design, study area and respondents’ characteristics.
Ethics approval is not required as this is a review of collected published data. Findings will be disseminated in peer-reviewed publications and conference presentations, as well as with key stakeholders, health policymakers and healthcare professionals.

Cervical cancer ranked fourth most common malignancy among women worldwide despite the establishment of vaccination programmes. This systematic review evaluates the anti-cancer properties of turmeric and ginger bioactive compounds, specifically curcumin, 6/10-gingerol, and 6/10-shogaol, and their combination in cervical cancer through in-vitro and in-vivo models. A comprehensive electronic search was performed using Science Direct, PubMed, and Scopus from inception until the second week of June 2024 for studies published in English. Only studies investigating the effects of curcumin, gingerol, shogaol, and/or their combination in human cervical cancer cell lines and/or rodent animal models implanted with cervical cancer xenografts were included. Altogether, 27 studies were included in this review. The evidence gathered indicated that curcumin, 6/10-gingerol and 6-shogaol exert their anticancer action through modulation of cell signalling pathways, including AMPK, WNT, PI3K/AKT, and NF‐κB pathway, and mediators including Bax/Bcl2, TNF‐α, EGFR, COX‐2, caspases‐3, ‐9, p53, and pRb. However, the synergistic effect of these bioactive compounds is not known due to lack of evidence. In conclusion, curcumin, 6/10-gingerols, and 6-shogaols hold promise as therapeutic agents for cervical cancer. Yet, further research is essential to understand their combined efficacy, emphasising the need for additional studies exploring the synergistic anticancer effects of these bioactive compounds. Additional factors to explore include long-term effects and susceptibility of chemoresistant cervical cancer cells towards curcumin, shogaols, and gingerols.
