Impact of folic acid and vitamin B12 supplementation on arsenic methylation

A recent study demonstrated that folic acid (FA) and vitamin B12 (B12) supplementation improved arsenic methylation in children, leading to a decrease in monomethyl- (MMAs) and an increase in dimethyl- (DMAs) in both blood and urine. Implementing nutritional interventions could enhance arsenic methylation and elimination in children, thereby reducing arsenic toxicity and improving their nutritional status. This study’s results were published in the Environment International journal.

This double-blind, placebo-controlled trial involved 240 participants aged 8-11 years, who were consuming water from wells with arsenic levels exceeding 50 μg/L. They were advised to switch to wells with lower arsenic levels and were randomly assigned to receive either 400 μg FA + 5 μg B12 or a placebo daily for a period of 12 weeks. Samples of urine and blood were taken at the baseline, week 1 (urine only), and week 12. Generalized estimated equation (GEE) models were utilized to evaluate the impact of the treatment on arsenic levels in both blood and urine.

At the baseline, the mean ± SD total urinary and blood arsenic levels were measured as 91.2 ± 89.5 μg/L and 5.3 ± 2.9 μg/L, respectively. After the follow-up period, there was an overall decrease of 11.7% in total blood arsenic and 17.6% in urinary arsenic. In comparison to the placebo group, the supplementation group showed a notable increase in blood DMAs concentration by of 14.0% and blood secondary methylation index (DMAs/MMAs) by 0.19 at 12 weeks. Additionally, the supplementation group had a significantly higher urinary %DMAs (1.62%) and a significantly lower urinary %MMAs (-1.10%) compared to the placebo group after 1 week. The effects of the treatment were stronger in individuals with higher baseline blood arsenic levels. These results remained consistent across both males and females, as well as participants with varying folate and B12 status at baseline.

Thus, it can be concluded that FA and B12 supplementation resulted in improved arsenic methylation in children, resulting in a reduction in MMAs and an elevation in DMAs in both blood and urine.

Similarly, it can be used for monitoring disease susceptibility and progression, monitoring treatment effectiveness, and assessing the likelihood of exacerbations.

Microbiome research can help us to understand the impact of the microbiome on child health and shed light on the relationship between gut bacteria, the immune system, the central nervous system, and metabolic processes.

Nanotechnology opens new possibilities for targeted drug delivery and precision medicine among children. Engineered nanoparticles with increased efficacy and minimal systemic toxicity can be potentially used in the treatment of pediatric cancer and viral infectious diseases.

The use of advanced fetal imaging technology and early treatment can prevent congenital abnormalities. Adolescent health research can help to deal with mental health problems, nutrition deficiency problems, and lifestyle diseases that Indian teenagers are facing today.

Pediatric interventional radiology includes advanced imaging technologies to diagnose and treat various conditions by utilizing minimally invasive procedures with less recovery time and complications. Improving access to interventional radiology in India has the potential to widen treatment options for pediatric cardiac defects, birth defects, and cancer-related issues.

To conclude, pediatric research in India can be transformed by navigating current challenges and seizing emerging opportunities. The integration of AI, microbiome research, nanotechnology, interventional radiology, and the progress in fetal as well as adolescent health will cater for precise diagnosis and personalized treatment plans, leading to improved health outcomes in children and adolescents.

The efficacy of lubiprostone in the treatment of functional constipation in adolescents and children

A recent study has shown that lubiprostone is effective and has good tolerability as a pharmacotherapy for children and adolescents, offering a potential shift in the treatment approach for pediatric functional constipation (FC). This study’s findings were published in the Journal of Pediatric Gastroenterology and Nutrition.

This single-blinded, randomized controlled trial included 280 patients (aged 8-18 years) with FC. These patients were randomly assigned to receive either a weight-based lubiprostone dose (n = 140) or conventional laxatives (n = 140), which included bisacodyl, lactulose, or sodium picosulfate, for a duration of 12 weeks. Subsequently, a 4-week posttreatment follow-up was carried out.

The lubiprostone group demonstrated an improvement in constipation in 91.4% (128 patients) when compared to 34.3% (48 patients) in the conventional therapy group and persisted even after treatment discontinuation. Additionally, within 48 hours of starting the medication, one quarter of the lubiprostone group experienced their first spontaneous bowel movement. Throughout the last 4 weeks of therapy and the subsequent 4 weeks of follow-up, 75.7% of the lubiprostone group maintained a Bristol stool form of 3 or 4 compared to 35.7% (50 patients) in the conventional therapy group. No life-threatening adverse drug reactions were reported, and no patients discontinued treatment due to adverse effects.

Thus, it can be concluded that lubiprostone may be a well-tolerated and effective pharmacotherapy for children and adolescents, presenting a promising alternative in the management of pediatric functional constipation (FC).

Parenteral n-3 polyunsaturated fatty acids enhances the postoperative recovery of individuals with Crohn's disease after bowel resection

According to a recent study, supplementation of parenteral n-3 polyunsaturated fatty acids improves postoperative recovery in Crohn's disease patients after bowel resection, leading to decreased complications and lower levels of inflammatory cytokines. This study’s findings were published in The American Journal of Clinical Nutrition.

In an unblinded, randomized, controlled clinical trial, 268 patients with Crohn's disease who underwent bowel resection were randomly assigned to two groups: 134 in the control group receiving a mix of long-chain and medium-chain fats at 1.0 g/kg/d, and 134 in the treatment group receiving long-chain, medium-chain, and n-3 polyunsaturated fats at 1.2 g/kg/d. This study compared postoperative complications, serum biochemical values, complete blood count, and cytokine concentrations in patients who received parenteral n-3 polyunsaturated fatty acids supplementation for 5 days after surgery and those who did not.

The results from both the intention-to-treat analysis and the per-protocol analysis indicate a significant decrease in overall complication rates (22.4% vs. 49.3%; P < 0.001 and 21.8% vs. 38.2%; P = 0.006) as well as a shorter postoperative stay (8.8 ± 4.5 d vs. 11.2 ± 6.8 d; P = 0.001 and 8.7 ± 4.0 d vs. 11.5 ± 7.3 d; P < 0.001) in patients who received parenteral n-3 polyunsaturated fatty acids supplementation compared to those in the control group. In terms of secondary outcomes, the treatment group exhibited significantly lower mean ± standard deviation levels of interleukin (IL)-6 (17.11 ± 2.14 pg/mL vs. 30.50 ± 5.14 pg/mL; P = 0.014), IL-1β (2.01 ± 0.05 pg/mL vs. 2.24 ± 0.09 pg/mL; P = 0.019), C-reactive protein concentrations (51.3 ± 4.2 mg/L vs. 64.4 ± 5.3 mg/L; P = 0.050), and tumor necrosis factor-α (2.09 ± 0.06 pg/mL vs. 2.29 ± 0.06 pg/mL; P = 0.029) on postoperative day 5 compared to the control group.

Thus, it can be concluded that the postoperative recovery in patients with Crohn's disease who have undergone bowel resection is significantly improved through the supplementation of parenteral n-3 polyunsaturated fatty acids. This intervention not only reduces complications but also lowers the levels of inflammatory cytokines.
