Standalone oblique lumbar interbody fusion versus oblique lumbar interbody fusion with posterior pedicle screw fixation for lumbar degenerative disease: A systematic review and meta-analysis

Oblique lumbar interbody fusion (OLIF) may be performed alone or with posterior pedicle screw fixation (PSF), but the trade-off between operative burden and mechanical durability remains uncertain. We compared perioperative, clinical, fusion, and cage-subsidence outcomes after st...

Optimization of Graptophyllum pictum leaf polyphenols via microwave extraction and antioxidant properties

Graptophyllum pictum (L.) Griff. leaves are traditionally used for various ailments and represent a promising source of antioxidant phenolic and flavonoid compounds. However, optimization of microwave-assisted extraction (MAE) to maximize total phenolic content (TPC) and total fl...

Nutritional status, clinical burden, and healthcare utilization among pediatric outpatients with congenital heart disease: A retrospective cross-sectional study from Indonesia

Congenital heart disease contributes substantially to chronic morbidity, growth impairment, and repeated healthcare utilization among children. Evidence regarding nutritional burden and outpatient healthcare patterns among pediatric patients with congenital heart disease in Indon...

"Smarter but Not Wiser": A Transdisciplinary CFA-GRM Simulation Pipeline for Mapping Human–GenAI Interaction

Background The integration of Generative AI (GenAI) in higher education creates a paradox between technical efficiency and cognitive depth. Current institutional responses rely more on fragmented oversight than on ecology- and process-oriented assessment. There is a lack of diagn...

The effect of red palm oil (Elaeis guineensis Jacq.) on skin hydration in streptozotocin-induced diabetic white rat models

Diabetes mellitus (DM) is frequently associated with cutaneous complications, including xerosis cutis, due to impaired skin barrier function. Red palm oil (RPO; Elaeis guineensis Jacq.) contains bioactive compounds with antioxidant, anti-inflammatory, and barrier-repair propertie...

The daily and seasonal biting patterns of the vectors of enzootic, zoonotic and human malarias, Anopheles dirus and Anopheles maculatus, in North Sumatra, Indonesia

Zoonotic malaria cases in humans are increasing across Southeast Asia including in Indonesia, but the vectors’ transmission dynamics are still poorly understood. Incriminating the vector species and defining their behaviours is essential to understanding zoonotic malaria transmis...

Solvent selection governs the performance of low-quality cat’s eye damar resin as a bio-based coating for biomass composite roof tiles

The growing demand for sustainable construction materials has increased interest in bio-based coatings from renewable resources. This study investigated the effect of solvent type on the performance of Cat’s Eye damar resin as a protective coating for sorghum bagasse composite ro...

Polypharmacy and Potentially Inappropriate Medications: Cognitive Consequences in Older Heart Failure Outpatients

Abstract Introduction Cognitive impairment is prevalent among older heart failure (HF) outpatients. Polypharmacy and potentially inappropriate medications (PIMs) may contribute to cognitive vulnerability, yet evidence using the Beers Criteria 2023 with locally validated cognitive...

Research trends on intimate partner violence against women during the COVID-19 pandemic: A bibliometric analysis and thematic research opportunities

Intimate Partner Violence (IPV) against women constituted a profound humanitarian tragedy, particularly during the COVID-19 pandemic. Consequently, mapping the scholarly literature produced on this topic is essential. This study aimed to map existing publications on IPV during th...

Graphicflow ultrasound in fetal echocardiography: principles, hemodynamics, clinical applications, and future perspectives

BACKGROUND: Graphicflow is a commercially available ultrasound technology that uses trajectory-based blood speckle tracking to display intracardiac blood-cell movement in real time during fetal echocardiography. Unlike conventional Doppler ultrasound, which mainly measures blood-...

Technological innovation adoption for improving smallholder cashew farmers’ income: The interconnection of institutional and market dimensions

Cashews are a critical export commodity of African and other developing countries, including Indonesia. Unfortunately, Indonesia’s exports continue to decline due to decreased production and low productivity. The science-technology-innovation approach plays a crucial role in fost...

Fuzzy K-nearest neighbor for fine particles focusing on big data challenges and Introducing the GreenDeen concept towards pollution mitigation

Abstract Rapid urban expansion and economic activity in densely populated cities have significantly contributed to worsening air quality. Jakarta, Indonesia’s capital, frequently experiences PM 2.5 concentrations that exceed "unhealthy" levels, posing serious public health risks....

Preoperative global longitudinal strain predicts myocardial hypertrophy burden but not the magnitude of reverse remodeling after surgical aortic valve replacement in severe aortic stenosis

Abstract Background Global longitudinal strain (GLS) is a marker of subclinical myocardial dysfunction and predicts adverse outcomes in severe aortic stenosis. However, its ability to predict the magnitude of left ventricular (LV) reverse remodeling following surgical aortic valv...

Ferroptosis in Anthracycline Cardiotoxicity: Mechanisms, the Cardioprotection Paradox and the Limits of Single‐Pathway Thinking

ABSTRACT Anthracyclines remain among the most effective cytotoxic drugs, but their cumulative cardiotoxicity limits dosing and threatens survivors with heart failure. The discovery that doxorubicin kills cardiomyocytes substantially through ferroptosis—an iron‐dependent, lipid‐pe...

Poison control centre in Indonesia: What are we waiting for?

In this letter, we present a case that drew significant public attention in Indonesia. The case involved a young boy who was bitten by a banded krait while sleeping. He was taken to a hospital, but due to delayed management, he eventually passed away. This case highlights the com...
