Objectives: The objective of this study was to report the integrated observations of high‐risk HPV‐related oral squamous carcinoma (OSCC) at our national referral center for cancer, the Dharmais National Cancer Hospital (DNCH), Jakarta, from 2003 to 2013.Materials and Methods: Seventy‐eight formalin‐fixed paraffin‐embedded specimens obtained from OSCC cases were collected from 2003 to 2013 DNCH archives and were included in this high‐risk HPV (HR‐HPV) study. Seventy‐nine DNA samples from the normal oral mucosa of healthy individuals were obtained from the Oral Biology Laboratory DNA archives from 2001 to 2005. Glyceraldehyde 3‐phosphate dehydrogenase was used as a control to ensure the DNA integrity for the subsequent HPV DNA PCR detection. High‐risk HPV16/18 DNA amplification was conducted by nested PCR using two pairs of primers that were designed specifically to identify the region of gene L1 HPV16 and the HPV16/18 region.Results and Conclusions: A high prevalence of HPV16/18 was detected in OSCC cases (17.9%). HPV18 occurred more often than HPV16 (86%) among OSCC patients who were HPV positive. This result supports high HPV18 prevalence among Indonesian cervical cancer patients studied in 1995 and 2006. The prevalence of high‐risk HPV remains low in the normal Indonesian population (3.8%), but HPV16 is consistently more frequently detected in non‐cancer populations.

This study aimed to assess the prevalence of blood lead levels (BLLs) among children 1 to 5 years old who reside near and distant to informally used lead-acid battery (ULAB) recycling locations and examine risk factors for elevated BLLs. A cross-sectional study was conducted in three greater Jakarta neighborhoods where informal ULAB recycling occurs. Venous BLLs among 279 children were analyzed using portable blood lead testing machines. Demographic, child activities, and sources of lead exposure inside and outside homes were assessed. Multivariate analysis was performed to evaluate factors associated with the prevalence of BLLs. Forty-seven percent of children had BLLs ≥ 5 µg/dL and 9% had BLLs ≥ 10 µg/dL. No differences in geometric mean BLLs were observed between children who lived near and distant to ULAB locations. Older child age groups [Prevalence Ratio (PR) 2.14, 95% Confidence Interval (CI) 1.16, 4.18) and low household income (PR 1.58, 95% CI 1.03, 2.40) were associated with BLLs 5–9 µg/dL. Low educational attainment of the child’s father (PR 3.17, 95% CI 1.23, 8.16) and frequent outdoor child activity (PR 4.93, 95% CI 1.09, 22.21) were predictors of BLLs ≥ 10 µg/dL. This study shows the association between lead exposure among children and environmental sources. Public health officials can consider expanded surveillance, health care provider education, and development of strategies to reduce lead exposure.

Essential fatty acids (EFA) such asα-linolenic acid (ALA) and linoleic acid (LA) are needed for healthy growth and development of children. Worldwide, reliable intake data of EFA are often lacking. The objective of this study was to investigate dietary intake of EFA in Indonesian children. Dietary intake data of 4–12-year-old children (n45 821) from a nationally representative Indonesian survey were used to estimate median intake and distribution of population fatty acid intake. Missing data on individual fatty acids in the Indonesian food composition table were complemented through chemical analyses of national representative food samples and imputation of data from the US nutrient database. Nutrient adequacy ratios were calculated as a percentage of FAO/WHO intake recommendations. The medians of total fat intake of the children was 26·7 (10th–90th percentile 11·2–40·0) percentage of total daily energy (%E). Intakes of fatty acids were 4·05 (10th–90th percentile 1·83–7·22) %E for total PUFA, 3·36 (10th–90th percentile 1·14–6·29) %E for LA and 0·20 (10th–90th percentile 0·07–0·66) %E for ALA. Median intake of PUFA was 67 % and that of ALA 40 % of the minimum amounts recommended by FAO/WHO. These data indicate that a majority of Indonesian children has intakes of PUFA and specifically ALA that are lower than recommended intake levels. Total fat and LA intakes may be suboptimal for a smaller yet considerable proportion of children. Public health initiatives should provide practical guidelines to promote consumption of PUFA-rich foods.

Dietary and plasma carboxymethyl lysine (dCML, pCML) and plasma tumor necrosis factor-α (pTNF-α) may be associated with obesity in affluent society. However, evidence in women from low-middle income countries with predominantly traditional diets is lacking. We investigated the mediator effects of dCML, pCML and pTNF-α on body mass index (BMI) and waist circumference (WC) among Indonesian women. A cross-sectional study was conducted among 235 non-diabetic, non-anemic and non-smoking women aged 19–50 years from selected mountainous and coastal areas of West Sumatra and West Java. Dietary CML, pCML, pTNF-α were obtained from 2 × 24-h recalls, ultra-performance liquid chromatography-tandem mass spectrometry and enzyme-linked immunosorbent assay, respectively. Between-group differences were analyzed by the Chi-square or Mann-Whitney test and mediator effects by Structural Equation Modeling. The medians and interquartile-ranges of dCML, pCML and pTNF-α were 2.2 (1.7–3.0) mg/day, 22.2 (17.2–28.2) ng/mL and 0.68 (0.52–1.00) IU/mL, respectively, and significantly higher in the WC ≥ 80 cm than in the WC < 80 cm group, but not in BMI ≥ 25 kg/m² compared to BMI < 25 kg/m² group. Plasma CML and pTNF-α were positively and directly related to WC (β = 0.21 [95% CI: 0.09, 0.33] and β = 0.23 [95% CI: 0.11, 0.35], respectively). Dietary CML that correlated with dry-heat processing and cereals as the highest contributions was positively related to WC (β = 0.33 [95% CI: 0.12, 0.83]). Ethnicity, level of education, intake of fat, and intake of energy contributed to dCML, pCML and pTNF-α, and subsequently affected WC, while only ethnicity contributed to BMI through dCML, pCML and pTNF-α (β = 0.07 [95% CI: 0.01, 0.14]). A positive direct effect of dCML on pCML and of pCML and pTNF-α on WC was seen among Indonesian women. Dietary CML seems to have several paths that indirectly influence the increases in WC if compared to BMI. Thus, intake of CML-rich foods should be reduced, or the foods consumed in moderate amounts to avoid the risk of central obesity in this population.

Background: Undernutrition and stunting are significant public health concerns globally, particularly in low- and middle-income countries. Nutritional intervention is the cornerstone of the management and prevention of these conditions. However, the gut microbiome has recently emerged as an essential modulator of the effects of nutritional interventions in undernutrition and stunting. This scoping review aims to examine the impact of nutrition intake (including if there is any intervention) over time on gut microbiome changes in infants and children under the age of 2 who experience undernutrition and stunting. Methods: A literature search was conducted in PubMed and Cochrane Library, including studies from 2013 to 2023, using terms related to malnutrition, stunting, failure to thrive, and gut microbiome. Inclusion criteria were applied to select eligible studies for review. Five studies were chosen to be included in this review. Results: The findings indicate that nutrition intake over time, including dietary supplementation and prebiotics, can influence the gut microbiome composition, diversity, and functionality in undernutrition and stunting infants and children. These may promote the growth of beneficial bacteria while reducing the abundance of harmful pathogens. Moreover, improvements in nutritional status, growth parameters, and immune function were observed in association with positive changes in the gut microbiota. Conclusion: Nutrition intake can positively modulate the gut microbiome in undernutrition and stunting infants by supporting the growth of beneficial gut bacteria such as Actinobacteria, Bacteroides, Streptococcus, Bifidobacterium, Prevotella sp, and other bacterial taxa that vary with age, ultimately contributing to enhanced growth and development outcomes. Further studies are needed to better understand the mechanisms underlying these effects and to develop targeted nutritional interventions that optimize the gut microbiome in undernutrition and stunting infants and children under 2 years.
