Enteral feeding is generally accepted in patients who cannot take nutrients orally. Percutaneous endoscopic gastrostomy (PEG) is a major enteral means for the introduction of nutritional solutions. However, jejunal feeding is sometimes employed instead of gastric feeding in cases of post-gastrectomy or repeated aspiration after PEG. The digestion and absorption of nutrients in trans-jejunal feeding might be different from those in trans-gastric feeding. In the present study, we measured the serum concentations of micronutrients and vitamins in the cases of direct percutaneous endoscopic jejunostomy (D-PEJ), compared to those of PEG. The enteral feeding has been continued for more than six months in all the cases. Serum copper and zinc concentration were significantly decreased in the D-PEJ group, whereas no significant difference in the concentrations of iron, selenium, vitamins A, B12 and E was ovserved between the two groups. Anemia and neutropenia were frequently observed in many patients with D-PEJ. These conditions were associated with copper deficiency. Much attention should be paid to copper and zinc deficiency in long-term trans-jejunal feeding.

Objective: In this study, we evaluated distinctive types of physical predisposition in patients with common side effects.
Method: We selected 500 and 1,200 individuals with and without a previous diagnosis of side effects, respectively, through web-based research. Then, we conducted a decision tree analysis for investigating the status of 100 types of physical predisposition in these individuals.
Results and Conclusion: The individuals who had suffered from hepatic disorder and answered “relevant” for “predisposition to swelling” (likelihood ratio of a positive result [LR+] 2.17; p=0.004) and “very relevant” for “predisposition to skin dryness” (LR+ 3.52; p<0.001) enhanced the probability of extracting individuals who developed side effects. The individuals who had suffered from skin disorder and answered “relevant” for “predisposition to eczema and inflammation” and “not relevant” for “predisposition to higher temperature” had an LR+ of 2.22 (p<0.001). The individuals with “predisposition to worsening of physical condition on a rainy or high-humidity day” are more likely to develop side effects with the use of antibiotics and NSAIDs, compared to those without this predisposition (antibiotics: LR+ 2.33; NSAIDs: LR+ 2.51). The results of this study indicate that we can identify patients with a high risk of side effects through an interview on predisposition.

BACKGROUND:
Pyrethroid (PYR) insecticides are widely used for controlling various pests. There are two types that differ in terms of usage: agricultural-purpose PYR (agriculture-PYR) and hygiene purpose PYR (hygiene-PYRs). Few studies exist on the exposure to these chemicals in small children. In this study, we conducted biomonitoring of urinary pyrethroid metabolites in 1.5-year-old children throughout the year.
METHODS:
Study subjects were 1075 children participating in an Aichi regional sub-cohort of the Japan Environment and Children's Study as of 18-month health check-up. The concentrations of four specific hygiene-PYR metabolites including 2,3,5,6-tetrafluoro-1,4-benzenedimethanol (HOCH2-FB-Al), and five common metabolites of hygiene- and agriculture-PYRs including 3-phenoxybenzoic acid (3PBA) and cis- and trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid (DCCA), were measured in urine samples extracted from soiled diapers using a triple quadrupole gas chromatograph-mass spectrometer.
RESULTS:
The highest detection frequencies were for 3PBA, followed by DCCA, 1R-trans-chrysanthemum dicarboxylic acid, and HOCH2-FB-Al. Among the six metabolites, urinary concentrations were seasonally varied. However, this variation was not observed in the most studied PYR metabolite, 3PBA. Spearman's correlation analysis demonstrated a significant positive correlation between FB-Al and DCCA (r = 0.56) and HOCH2-FB-Al and 4-methoxymethyl-2,3,5,6-tetrafluorobenzyl alcohol (r = 0.60).
CONCLUSIONS
This biomonitoring survey found widespread and seasonally specific exposure to multiple hygiene- and agriculture-PYRs in 1.5-year-old Japanese children.
