METHODS: We conducted a population-based study using data from the Global Cancer Observatory (GLOBOCAN) 2022 and predicted global radiotherapy demands and workforce requirements in 2050. We obtained incidence figures for 29 types of cancer across 183 countries and derived the cancer-specific radiotherapy use rate using the 2013 Collaboration for Cancer Outcomes Research and Evaluation model. We delineated the proportion of people with cancer who require radiotherapy and can be accommodated within the existing installed capacity, assuming an optimal use rate of 50% or 64%, in both 2022 and 2050. A use rate of 50% corresponds to the global average and a use rate of 64% considers potential re-treatment scenarios, as indicated by the 2013 Collaboration for Cancer Outcomes Research and Evaluation (CCORE) radiotherapy use rate model. We established specified requirements for teletherapy units at a ratio of 1:450 patients, for radiation oncologists at a ratio of 1:250 patients, for medical physicists at a ratio of 1:450 patients, and for radiation therapists at a ratio of 1:150 patients in all countries and consistently using these ratios. We collected current country-level data on the radiotherapy-professional workforce from national health reports, oncology societies, or other authorities from 32 countries.
FINDINGS: In 2022, there were an estimated 20·0 million new cancer diagnoses, with approximately 10·0 million new patients needing radiotherapy at an estimated use rate of 50% and 12·8 million at an estimated use rate of 64%. In 2050, GLOBOCAN 2022 data indicated 33·1 million new cancer diagnoses, with 16·5 million new patients needing radiotherapy at an estimated use rate of 50% and 21·2 million at an estimated use rate of 64%. These findings indicate an absolute increase of 8·4 million individuals requiring radiotherapy from 2022 to 2050 at an estimated use rate of 64%; at an estimated use rate of 50%, the absolute increase would be 6·5 million individuals. Asia was estimated to have the highest radiotherapy demand in 2050 (11 119 478 [52·6%] of 21 161 603 people with cancer), followed by Europe (3 564 316 [16·8%]), North America (2 546 826 [12·0%]), Latin America and the Caribbean (1 837 608 [8·7%]), Africa (1 799 348 [8·5%]), and Oceania (294 026 [1·4%]). We estimated that the global radiotherapy workforce in 2022 needed 51 111 radiation oncologists, 28 395 medical physicists, and 85 184 radiation therapists and 84 646 radiation oncologists, 47 026 medical physicists, and 141 077 radiation therapists in 2050. We estimated that the largest proportion of the radiotherapy workforce in 2050 would be in upper-middle-income countries (101 912 [38·8%] of 262 624 global radiotherapy professionals).
INTERPRETATION: Urgent strategies are required to empower the global health-care workforce and facilitate the fundamental human right of access to suitable health care. A collective effort with innovative and cost-contained health-care strategies from all stakeholders is warranted to enhance global accessibility to radiotherapy and address challenges in cancer care.

METHODS: Data were collected across four sites: the United States, the United Kingdom, China, and Malaysia. The Childhood Trauma Questionnaire (CTQ), Suicidal Behaviors Questionnaire-Revised (SBQ-R), and International Trauma Questionnaire (ITQ) were used to assess childhood maltreatment, suicidality, and PTSD or CPTSD, respectively. Linear regressions were conducted to examine the associations, controlling for demographic variables (age, sex, ethnicity, educational level, and subjective socioeconomic status) as well as the severity of maltreatment (CTQ total scores).
RESULTS: Among the 1324 participants who experienced childhood maltreatment, meeting the criteria for CPTSD was significantly associated with higher suicidality compared to not meeting the criteria for either PTSD or CPTSD (B(SE) = 1.68 (0.30), p
METHODS: The design was a parallel double blind, randomized clinical trial. Mature teeth with caries radiographically extending ≥ 2/3 of dentine and without spontaneous pulpitis were included. Teeth were allocated to either selective (SCR) or total caries removal (TCR) using block randomization technique. In the SCR group, caries removal to firm dentine was followed by placement of Biodentine and composite restoration. In TCR group caries removal was to hard dentine; with immediate management by vital pulp therapy (VPT) using Biodentine in case of pulp exposure. Preoperative pain levels were recorded. Teeth were followed up after 6 and 12 months. Data were analyzed using Chi square test and regression analysis.
RESULTS: 124 teeth with a diagnosis of reversible pulpitis were treated (63 in SCR, 61 in TCR). 17/ 61 teeth (28%) in the TCR had pulp exposure, managed by VPT and were successful at recall. Pulp survival was significantly higher in TCR compared to SCR at 6 months (100 % vs 93.65%, p =0.04 respectively) and at 12 months (98.4% vs 82.5, P= 0.003 respectively). Multivariate analysis revealed the type of procedure (SCR vs TCR) and the preoperative pain levels (above or below 5/10) as significant prognostic factors. The odds of failure increased significantly for teeth treated with SCR (OR 27.6, 3.6-212.4, p=0.001) and if preoperative pain levels were ≥5/10 (OR 0.2, 0.04-0.8, P=0.024).
CONCLUSION: Selective caries removal for deep carious lesions in mature teeth failed to reveal overt pulp exposures in more than one quarter of cases and led to significantly lower pulp survival over one year, when compared with complete caries removal and immediate VPT.
CLINICAL SIGNIFICANCE: In deep carious lesions of mature permeant teeth with revrsible pulpitis, total caries removal to hard dentine is recommended for a predictable pulp survival.
CLINICAL TRIAL REGISTRATION: This trial was registered at CliniclTrials.gov (NCT05144711).
METHODS: Through 25 semi-structured in-depth interviews, themes were identified using thematic analysis, guided by the Technology Readiness and Acceptance Model (TRAM).
RESULTS: Anticipated convenience and benefits, openness to new technologies acted as drivers, while limited digital literacy and concerns about data privacy and security served as inhibitors of readiness to adopt health apps. Acceptance was influenced by elements related to medication, patient, healthcare professional, family and app aspects. The identified barriers were related to patient, smartphone and monetary factors. Patients perceived the need to adopt digital apps were for those with poor adherence, complex medication regimen and forgetfulness issues. However, concerns about effectively implementing this approach were noted as T2DM patients were predominantly late middle-aged adults who faced technical challenges, leading to combination approach between digital technology and conventional patient education and counselling.
CONCLUSION: The findings highlighted the factors influencing patient's readiness, acceptance, and barriers on effective utilisation of digital health solutions in managing adherence issues.
PRACTICAL IMPLICATIONS: The elements of TRAM provide guidance for strategic actions to enhance digital health technology adoption among T2DM patients.
MATERIAL AND METHODS: Periodontal tissues were obtained from extracted human teeth and processed for PDLF culture. The cells were then exposed to six experimental media: (i) HBSS, (ii) HBSS and ascorbic acid (HBSS + Vit C), (iii) HBSS and platelet-derived growth factor (HBSS + PDGF), (iv) a mixture of HBSS, PDGF, and Vit C (HBSS + PDGF + Vit C), (v) HBSS and platelet lysate (HBSS + PL), and (vi) DMEM for 3, 6, 12, and 24 h. A MTT assay was performed to determine the cell viability.
RESULTS: Vitamin C-containing media maintained PDLF viability significantly better than HBSS + PDGF and HBSS + PL at 3, 6, 12, and 24 h (p HBSS+Vit C; HBSS+PDGF+Vit C>HBSS+PL>HBSS+PDGF; HBSS). Although DMEM had the highest cell proliferative effect, it is impractical to be used as a transport medium due to its cost, storage, and availability. The supplementation of Vit C yielded significant cell proliferative effects; hence, HBSS + Vit C can be a better alternative as a storage medium than HBSS.
METHODS: A systematic search of PubMed, Web of Science, and Embase was conducted for studies published up to August 2024. Eligibility criteria included cohort, case-control, and cross-sectional studies assessing air pollution exposure and mortality in PLWH. Nested-Knowledge software was used for screening and data extraction. The Newcastle-Ottawa Scale was applied for quality assessment. A narrative approach and tabular summarization were used for data synthesis and presentation.
RESULTS: Nine studies, mostly from China, demonstrated a significant association between long-term exposure to PM1, PM2.5, and PM10 and increased risks of AIDS-related and all-cause mortality in PLWH. Hazard ratios for mortality increased by 2.38-5.13% per unit increase in PM concentrations, with older adults (> 60), females, and those with lower CD4 counts (
METHODS: This double blinded randomized controlled trial was conducted in University Malaya Medical Centre between October 2019 and March 2022. Patients undergoing emergency laparotomy requiring incisions less than 35 cm were included. Statistical analysis was performed using χ2 test for categorical variables, independent T-test or Mann-Whitney U were used for parametric or non-parametric data respectively besides logistic regression. P values of
METHODS: Forty-seven participants were recruited via convenient sampling during a RA workshop for novice practitioners. They were divided into the N or B group and then crossover to experience using both Blue Phantom and NeedleTrainer model. Time-to-reach-target, first-pass success rate, and complication rate were assessed, while the learning and confidence scores were rated using six-item and three-item questionnaires, respectively, via a 5-point Likert scale.
RESULTS: Blue Phantom model has a longer time-to-target as compared to the NeedleTrainer model (16 ± 8 vs 8 ± 3 s, p
METHODS: The D-PRISM study was a multinational, survey-based investigation to assess the diagnosis and treatment of pneumonia in the ICU. A self-administered online questionnaire was distributed to intensive care clinicians from 72 countries between September to November 2022. The questionnaire included sections on professional profiles, current clinical practice in diagnosing and managing CAP, HAP, and VAP, and the availability of microbiology diagnostic tests. Multivariable analysis using multiple regression analysis was used to assess the relationship between reported antibiotic duration and organisational variables collected in the study.
RESULTS: A total of 1296 valid responses were collected from ICU clinicians, spread between low-and-middle income (LMIC) and high-income countries (HIC), with LMIC respondents comprising 51% of respondents. There is heterogeneity across the diagnostic processes, including clinical assessment, where 30% (389) did not consider radiological evidence essential to diagnose pneumonia, variable collection of microbiological samples, and use and practice in bronchoscopy. Microbiological diagnostics were least frequently available in low and lower-middle-income nation settings. Modal intended antibiotic treatment duration was 5-7 days for all types of pneumonia. Shorter durations of antibiotic treatment were associated with antimicrobial stewardship (AMS) programs, high national income status, and formal intensive care training.
CONCLUSIONS: This study highlighted variations in clinical practice and diagnostic capabilities for pneumonia, particularly issues with access to diagnostic tools in LMICs were identified. There is a clear need for improved adherence to existing guidelines and standardized approaches to diagnosing and treating pneumonia in the ICU. Trial registration As a survey of current practice, this study was not registered. It was reviewed and endorsed by the European Society of Intensive Care Medicine.
OBJECTIVE: To demonstrate Malaysia's experience in implementing ICD-11, from data collection to downstream data use applications.
METHOD AND IMPLEMENTATION: We describe improvements to existing data source systems and downstream data applications. For non-HIS and HIS (ICD-10) systems, data were manually entered into the health management information system equipped with ICD-11 or automatically mapped from ICD-10 to ICD-11. Following these system improvements, we collected and reported ICD-11 data from all hospitals nationwide, regardless of the individual systems' status in ICD-11 use.
DISCUSSION: Lessons learnt related to legacy systems; ICD-11 releases and system updates; mapping; reporting; human resources and related applications.
CONCLUSION: With careful planning, standardisation of the collection and use of ICD-11 data can be accomplished with limited resources and in a complex environment with heterogeneous systems.
IMPLICATIONS: Use of ICD-11 data in downstream data applications improves data quality to answer specific business or research questions.
METHOD: Data from the Tobacco and E-Cigarette Survey among Malaysian Adolescents (n = 13,117) were analysed. Ordered probit models were used to assess factors associated with passive smoking risk perception (i.e. not harmful, probably not harmful, probably harmful, harmful).
RESULTS: About one-third of adolescents did not perceive that passive smoking was harmful (30.4%). Adolescents with the perception that passive smoking was not harmful were more likely to be students at low grade levels, be males, be non-Malays and be low-pocket-money recipients and those who used e-cigarettes and who smoked. Being aware of anti-smoking advertisements (direct effect = 0.174; indirect effect = 0.012) and taught on the dangers of smoking (direct effect = 0.179; indirect effect = 0.003) partially mediated the positive relationship between grade levels and perceived risk of passive smoking.
CONCLUSION: Policies implemented to reduce exposure to passive smoking should highlight the important role of demographic factors, lifestyle profiles, anti-smoking advertisements and education about the dangers of smoking in improving passive smoking risk perception among adolescents.
