Abstract

Background Malnutrition is still a major health problem for children, with stunting being one of its manifestations. Human growth is in part controlled by the mammalian target of rapamycin (mTOR) pathway. Studies reviewing mTOR level and growth disorders in children are still limited and no research has described mTOR levels in stunted children in Indonesia. Objective To assess for a relationship between mTOR and total protein levels in blood plasma in stunted children aged 6-24 months and compare these levels with those in non-stunted children. Methods This case-control study was conducted in South Sumatra Province, Indonesia. Subjects were children aged 6-24 months. The inclusion criteria for the case group are children who have a length-for-age of <-2SD and the control group are children who have a body length according to age of more than or equal to -2 SD from the WHO growth standard chart. Anthropometric measurements were plotted on the WHO Growth Standards chart, while mTOR and total protein levels were measured using an ELISA method and spectrophotometry, respectively. Results Of 142 subjects, 71 children were allocated into each case and control group. Child characteristics that were significantly different between the two groups were age (P=0.002), birth length (P=0.012), weight-for-age Z-score (WAZ) (P<0.001), and body mass index (BMI) (P=0.015). WAZ status with the categories underweight and severely underweight had a higher risk of stunting. The mTOR and total protein levels between the two groups were not significantly different. Conclusion Further research is needed to explain the mechanism of mTOR signal deviations in children's growth and development, as mTOR and protein levels are not significantly different in stunted and non-stunted children.

Abstract

Syarat penting untuk terjadinya kehamilan, yaitu blastokista pada fase tertentu siap melakukan implantasi dan proliferasi endometrium, sehingga menjadi reseptif terhadap embrio untuk melakukan implantasi. Pada tahap selanjutnya, masih terdapat proses molekular yang berkesinambungan sampai pada akhirnya terjadi hubungan langsung antara blastokista dan dinding endometrium dengan membentuk plasenta. Implantasi yang tidak efisien tentunya akan menyebabkan kegagalan implantasi, sehingga muncul masalah infertilitas. Sebanyak 30% kasus kegagalan kehamilan disebabkan oleh masalah kesehatan embrio. Pemahaman yang lebih mendalam mengenai sinyal-sinyal yang berperan pada kedua proses berkesinambungan tersebut diharapkan dapat memberikan metode terapi yang baru pada kasus infertilitas, sehingga meningkatkan jumlah kehamilan.

Abstract

Background: Adequate nutrient intake in early childhood is critical for growth, cognitive development, and immune function. The first two years of life are a sensitive period where nutritional deficiencies may lead to long-term consequences. However, many children in low- and middle-income countries fail to meet dietary needs due to limited diversity and poor feeding practices. Objectives: To describe the intake of energy, macronutrients, and key micronutrients among Indonesian children aged 6–24 months

Abstract

BACKGROUND: The burden of disease due to lead exposure continues to increase. Lead interferes with 25(OH)D hydroxylation and calcium transport, increasing osteoclastic activity and bone resorption. Pyridinoline crosslinks (PYD), as an indicator of bone damage, can be seen earlier compared to imaging changes. Therefore, it is necessary to determine the correlation between serum 25(OH)D levels and the urinary PYD/creatinine ratio in workers exposed to lead, since up to now, there are only limited studies related to it.METHODS: This cross-sectional study involved 104 workers exposed to lead, selected from parents whose children had blood lead levels above 10 µg/dL. Questionnaires and physical examination were performed to obtain characteristic data from subjects. Data regarding blood lead levels, serum 25(OH)D levels, urinary PYD levels, and urinary creatinine levels were also obtained from various laboratory methods.RESULTS: Most subjects (86.5%) had inadequate serum 25(OH)D. Median blood lead levels was 6.3 (1.2-35.5) µg/dL, chronic lead exposure index was 35.3 (1.2-535.8) years µg/dL, serum 25(OH)D levels was 22 (8-52) ng/mL, and urinary PYD/creatinine ratio was 5.3 (3.6-28.1)×10-6. There was a significant negative correlation between serum 25(OH)D levels and urinary PYD/creatinine ratio in workers exposed to lead. There was also a significant positive correlation between chronic lead exposure index and the urinary PYD/creatinine ratio.CONCLUSION: Since urinary PYD/creatinine ratio is correlated with serum chronic lead exposure index and serum 25(OH)D levels, it suggests that pyridinoline might be a potential biomarker to detect bone metabolism disorder due to the chronic lead exposure. Vitamin D adequacy is also an important factor in preventing bone metabolism disorder amidst chronic lead exposure.KEYWORDS: 25(OH)D, bone resorption, pyridinoline, lead, worker

Abstract

Hyperbaric oxygen therapy (HBOT) has gained increasing attention as a potential adjunctive treatment for traumatic brain injury (TBI) patients. This narrative review discusses the historical background, current preclinical and clinical studies, and explores its underlying mechanisms from biomolecular, histological, and clinical perspectives. HBOT promotes neural recovery by improving oxygenation, preserving mitochondrial integrity, enhancing neurotrophic support and synaptic connectivity, mitigating secondary injury pathways (including oxidative stress, inflammation, and apoptosis), and promoting angiogenesis and vascular stability. These mechanisms have demonstrated improvements of motor, cognitive, and memory functions both in preclinical and clinical studies, although outcomes and treatment protocols vary. However, challenges remain regarding optimal protocols, patient selection, and adverse effects. Further high-quality clinical trials are required to define the optimal HBOT regimen are required.

Abstract

Obesity is commonly associated with chronic low-grade inflammation and alterations in skeletal muscle mass, increasing the risk of sarcopenic obesity. Vitamin D deficiency and elevated C-reactive protein (CRP) levels are frequently observed in individuals with obesity and may contribute to impaired muscle metabolism. This study aimed to examine the relationship between vitamin D intake, plasma C-reactive protein (CRP) levels, and the Appendicular Skeletal Muscle Index (ASMI) among obese adults at Universitas Indonesia Hospital (RSUI). An analytical cross-sectional design was employed involving 70 obese adults aged 18–59 years. Vitamin D intake was assessed using a semi-quantitative food frequency questionnaire, plasma CRP levels were measured using enzyme-linked immunosorbent assay (ELISA), and ASMI was determined using bioelectrical impedance analysis. Data were analyzed using univariate, bivariate, and multivariate statistical methods. The results showed that most participants had inadequate vitamin D intake and elevated plasma CRP levels, indicating the presence of systemic inflammation. No significant association was found between vitamin D intake and CRP levels or between vitamin D intake and ASMI. However, plasma CRP levels demonstrated a weak but statistically significant association with ASMI. These findings suggest that inflammation plays a more prominent role than vitamin D intake in influencing skeletal muscle mass among obese adults, highlighting the multifactorial nature of sarcopenic obesity.
