Four Countries Have Antimicrobial-Stewardship Policies, but 16 Hospitals Average 72% Implementation and Training Lags

This study linked national policy, hospital systems, and provider behaviour in Indonesia, Nepal, Thailand, and Viet Nam during 2022–2023. It included 486 participants across 16 hospitals. All countries had antimicrobial-stewardship policies, but financing, enforcement, training, microbiology-data use, and inter-programme coordination were uneven. Hospitals averaged 72% on G-ASET, with tracking and reporting highest at 75% and training lowest at 66%. The two Thai hospitals scored 81.3% and 80.6% overall, yet both scored only 50% for training. These results identify actionable system gaps; they do not experimentally show that any intervention reduced antibiotic use, resistance, or mortality.

Regional policy evidence synthesis

Thalassaemia prevention in Asia: progress, challenges, and future directions

This Series paper reviews thalassaemia prevention across 14 Asian countries with high carrier frequencies, heterogeneous mutations, and unequal health-system capacity. Singapore, Malaysia, the Maldives, and Thailand had the most structured approaches, combining public awareness, carrier screening, genetic counselling, and prenatal diagnosis. Measurable success was clearest in Singapore and to a more limited extent Thailand. Many countries still face fragmented services, weak national coordination, workforce shortages, insufficient epidemiological data, and financial, technological, cultural, and social barriers. This is a regional health-system synthesis, not a comparative policy trial.

Observational cross-sectional evidence

Hepatitis B Vaccination Intention and Influencing Factors among College Students in Huanggang, Hubei, China: A Protection Motivation Theory-Based Cross-Sectional Study

This Protection Motivation Theory cross-sectional study surveyed 1,130 students aged 18–26 at three universities in Huanggang, Hubei, China, during April–May 2025. The authors dichotomized a 1–10 intention item into low scores of 1–6 and high scores of 7–10; 58.9% were in the high-intention group. In adjusted analysis, hepatitis B knowledge, vaccine knowledge, preventive behaviour, perceived severity, self-efficacy, and response efficacy were associated with higher odds of high intention, while perceived response cost was associated with lower odds. The findings identify intervention targets but do not show that changing them raises actual vaccination uptake.

Regional epidemiological synthesis

The Epidemiology of Thalassaemia Syndromes in Southeast Asia

This Series paper synthesizes thalassaemia epidemiology across 10 countries in WHO's South-East Asia Region by combining local expertise with a rapid literature review. Alpha- and beta-globin disorders and haemoglobin E are frequent and produce phenotypes ranging from asymptomatic carriage to lifelong transfusion dependence. Although a small set of mutations often dominates within each country, the regional spectrum is complex and population data remain incomplete. The paper highlights blood shortages, consanguinity in some settings, gender inequities, migration, and low awareness, and recommends national registries, premarital or prenatal screening, coordinated blood systems, and culturally sensitive education.

Crude-Glycerin Leucaena Pellets Improve Goat Feed Efficiency, but Methane Reduction Is Modeled

Thai researchers tested Leucaena leucocephala pellets containing 0–15% crude glycerin in 32 male Boer × Thai native goats for 90 days. Intake fell slightly, but gain-to-feed ratio, fermentation indicators, and modeled economics improved. Methane and greenhouse-gas reductions were estimated from a stoichiometric model rather than direct emissions measurements.

Techno-economic case-study scenario analysis

Techno-Economic Assessment of EV Charging Infrastructure in Residential Buildings in Nonthaburi, Thailand

This Nonthaburi residential-building case study compared two 60-kW DC chargers, one 60-kW DC plus two 22-kW AC chargers, and four 22-kW AC chargers. Assumptions included a seven-year project, 5.5% discount rate, mean selling price of THB7.25/kWh, service time of 4, 6, or 8 hours per day, and electricity costs of THB4.50, 4.73, or 4.95/kWh, giving 27 scenarios. All three portfolios were financially feasible under the specified conditions. Two DC chargers gave the strongest return at eight hours per day and THB4.50/kWh, while four AC chargers better fit long parking durations and lower capital and maintenance costs.

Visual Impairment Was Associated With Nearly Threefold Higher Odds of Frailty Progression in Thai Older Adults

This retrospective cohort from the Siriraj Primary Care Unit followed 400 community-dwelling older adults, with a median age of 70 years and 76% women. Visual impairment was defined as visual acuity worse than 6/12 in the better-seeing eye, and frailty was assessed with the Thai FRAIL scale. Ordinal logistic regression found an association with transition to a worse frailty state: adjusted odds ratio 2.98 (95% CI 1.97–4.52; p

NECTIN2 Depletion Cut Migration and Invasion by About Half, but Only in One Triple-Negative Breast Cancer Cell Line

This study asked whether the cell-surface adhesion molecule NECTIN2 contributes to motility and invasion in triple-negative breast cancer. The team combined public-dataset analyses with stable NECTIN2 depletion in MDA-MB-231 and MDA-MB-468 cells. The major phenotype was confined to MDA-MB-231: migration and invasion fell by about 50%, accompanied by lower LIMK1 and cytoskeletal changes, while LIMK1 re-expression partially restored migration. The findings support a context-dependent mechanism, not a clinically validated drug target or proof that NECTIN2 inhibition prevents metastasis in patients.

Antimicrobial Stewardship92IMPACT SIGNAL
Stepped-Wedge Cluster Randomized Trial

A Smartphone Antimicrobial Prescribing App Did Not Outperform Paper Guidelines Across Six Lao Hospitals

Across a stepped-wedge cluster randomized trial in six Lao hospitals, a smartphone version of national antimicrobial prescribing guidelines plus one stewardship training session did not significantly improve adherence over paper versions after adjustment for time, clustering, and confounders. Inpatient adherence was 25.6% versus 17.0% before adjustment, but the adjusted odds ratio was 1.26 (95% CI 0.8–1.9; p=0.276); outpatient results were also null. The finding argues for sustained, multifaceted stewardship rather than guideline access alone.

Model-development and benchmark evidence

Two-Stage Model Classifies 46 Produce and Vegetable-Dish Categories at 92.43% Top-1 Accuracy, but Lacks On-Device Validation

The study developed a two-stage ThaiSook pipeline: a binary model first rejects non-produce images, after which a multiclass model identifies 43 fruit and vegetable types and three vegetable-heavy dishes. The 40,595-image dataset contained 11,210 labelled and 29,385 unlabelled user images. With label smoothing and temperature scaling, the pipeline reached 92.43% top-1, 94.56% top-3, and 94.91% top-5 accuracy; Noisy Student raised top-1 accuracy to 92.59%. However, results rely on one train–test split, without real on-device testing or evidence that classification improves dietary measurement or health outcomes.

Lower-Income Asia-Pacific Settings Reported Full Out-of-Pocket Cost for 95.2% of High-Benefit Medicine–Country Pairs

This predefined regional analysis of ESMO's 2023 global survey covered 20 Asia-Pacific countries and compared WHO essential cancer medicines with high-benefit medicines under ESMO-MCBS. The findings show that marketing availability does not equal reliable access: reimbursement and patient out-of-pocket burden remain major bottlenecks. Access was generally stronger in high-income economies, while middle- and lower-income groups faced large gaps, particularly for high-benefit medicines. The evidence is expert-reported and cross-sectional, and income-group aggregates must not be presented as Thailand-specific estimates.

GEDI–Sentinel Model Maps Northeast Thai Rubber at 82.63% Accuracy but Struggles With Young Plantations

This study mapped 2024 rubber distribution and age structure across Northeast Thailand using Random Forest in Google Earth Engine, combining Sentinel-1, Sentinel-2, vegetation indices, and a GEDI-trained canopy-height model. Three-class rubber mapping reached 82.63% overall accuracy and about 0.84 F1; three-group age classification reached 83.39%. Plantations older than seven years dominated and were classified more reliably than young stands. The output is a regional monitoring baseline, not an error-free parcel-level decision map.

Advance-Care-Planning Training Raised Residents’ Knowledge From 7.74 to 8.65, but Had No Control Group

This mixed-methods evaluation tested an Advance Care Planning programme combining role-play, personal-value reflection, and two Circle of Learning sessions with an entire cohort of 50 first-year internal-medicine residents. Longitudinal analysis used 34 complete cases through 15 months, and 10 residents were interviewed. Knowledge rose from 7.74 to 8.65 out of 9, alongside several attitude and confidence improvements. Interviewees said role-play bridged theory and practice but identified a need for ongoing workplace support. The evidence concerns learner readiness, not observed conversation quality or patient outcomes.
