Risk assessment of soil contaminated with radionuclides was performed by considering the intake of radionuclides in foods based on measured concentrations. Due to the disaster at the Fukushima nuclear power plant in 2011, radionuclides were spread out over an area of 13,000 km2. Radionuclides were found in the food, and the Japanese people are concerned about eating foods from Fukushima and the surrounding area. Radionuclides such as 134Cs and 137Cs were found on soil, buildings, plants, and so on. The exposure routes were determined to be (1) food intake, (2) ingestion and inhalation of soil particles, and (3) external radiation from the ground. Then, the total doses of all exposure routes for one year and over a lifetime were calculated, and the committed effective doses for the lifetime were evaluated. To estimate the intake of food, the concentrations can be obtained from the database of the Ministry of Health and Welfare. The foods are divided into 16 types to estimate the daily intake. The geometrical means of the intake were calculated using monthly data for each group of food. Then, the intake from food for one year was calculated for each generation. The committed effective doses were calculated using the intake of each radionuclides times the dose coefficient. For the air dose, three cases were set as exposure scenarios. Case 1 was used for people who stay in a house for 24 hours, such as infants, pregnant females, and bedridden people. Case 2 was used for house wives and office workers, who stay outside for 4 hours and inside for 20 hours. Case 3 was used for children, farmers, and construction workers, who stay outside for 8 hours and inside for 16 hours. As a result, exposure through the ingestion and inhalation of soil particles were negligible, and exposures by food intake and external exposure from the ground were comparatively large. This study shows that the air dose by this disaster should be less than 0.2 μSv/hour to control the radiation dose with the consumption of food being less than 1 mSv/year. However, to maintain the lifetime dose under 100 mSv, several mSv/y is sufficient, considering radioactive decay and dilution by advection and diffusion. The risk assessment based on land use can provide information about the priority of countermeasures against the contamination and provides reasonable decontamination methods or risk management strategies.

The exposure routes by which the dispersion of radionuclides from the accident at the Fukushima atomic power plant were estimated, and the risk was evaluated based on the overall exposure routes, which include the ingestion of food, ingestion and inhalation of soil, and external air dose. This study shows that the air dose from this disaster should be less than 0.2 μSv/h to control the radiation dose with the consumption of food being less than 1 mSv/yr. However, to maintain the lifetime dose under 100 mSv, several mSv/yr is sufficient, considering radioactive decay and dilution by advection and diffusion.

Background: Sulphites added as preservatives in food have been associated with adverse health effects in humans. Objective: The present study was designed with an objective of assessing the risk of sulphite exposure through food in adolescents (12-16 years old) of Delhi, India. Methods: A total of 1030 adolescents selected from four private and four government schools of Delhi, were asked to record their food intake using a 24 hour food record, repeated on three days, for assessing exposure to sulphites. The risk was assessed using six different scenarios of exposure. Results: The actual intake for sulphites for average consumers was 0.15 ± 0.13 mg / kg b.w. / day which was 21.4% of acceptable daily intake (ADI). For high consumers (P95), it was 65% of the ADI. However, for 2 respondents, the actual intake exceeded the ADI. The major food contributors to sulphite intake were beverage concentrates (46%), ready to serve beverages (22%) followed by miscellaneous food items (16%), mainly ice creams and snowballs. Estimation of sulphite intake using different exposure scenarios revealed that for certain scenarios where the highest reported sulphite level or maximum permissible levels were considered for calculation, the high consumers exceeded the ADI, though, for average consumers, intake was well below the ADI. Conclusion: Actual intake of sulphite for average consumers was well below the ADI but for high consumers was approaching the ADI. People with sulphite sensitivity need to be aware of hidden food sources of sulphites.

Harmful Effects

Patulin is a mycotoxin for which a provisional maximum tolerable daily intake (PMTDI) of 400 ng/kg bodyweight/ day has been set based on its most sensitive toxic effect, growth retardation. Apple containing products are the major source for patulin exposure, with major intake differences according to age and living region. Young children are most at risk of patulin intoxication, because they consume much higher amounts of apple products than adults. In this study, the patulin intake was calculated for Dutch children of 8 to 48 months and the risks of patulin intoxication were assessed. In addition, the bioaccessibility of patulin from apple containing products was investigated for a more refined risk assessment of patulin. The bioaccessibility of patulin was high, varying between 55 and 100%, and, consequently, no refinement of the risk assessment was possible. Based on the probabilistic intake calculations, children are exposed to levels below the PMTDI. Children aged 13-20 months with a high organic apple product intake have the highest patulin exposure, 342 ng/kg bodyweight/day at the upper confidence interval of the P95. No harmful effects are expected with the current patulin intake in young children. No concentration data are available for baby food (organic and conventional) and, therefore, concentrations were set at half the legal limit for intake calculations. Concentration data are needed for a more refined intake calculation for children younger than one year to estimate the actual risk in these children, because baby food comprises 23% of their diet.

Domestic Violence Screening

This study seeks to determine the concurrent and predictive validity of a dual risk assessment protocol. It combines the risk of persistence in intimate partner violence (IPV) measured via the Domestic Violence Screening Instrument–Revised (DVSI-R) with supplemental items from the Danger Risk Assessment (DRA) bearing on the risk of potential lethality. We further test whether this assessment protocol reproduces disparities by race and ethnicity found in the larger population. Using a sample of 4,665 IPV male defendants with a female victim, analyses support both types of criterion validity. The DRA risk score is associated with felony charges, incarceration at the initial arrest, and the frequency of subsequent dangerous behavior. Results also suggest minimal predictive bias or disparate impact by race and ethnicity. Incorporating supplemental items bearing on potential lethality risk adds important information concerning the risk management strategies of those involved in IPV.

Objective. Diabetes care is an important part of family practice. Previous work indicates that diabetes management is variable. This study aimed to examine diabetes care according to best practices in one part of Ontario. Design and Participants. A retrospective chart audit of 96 charts from 18 physicians was conducted to examine charts regarding diabetes care during a one-year period. Setting. Grimsby, Ontario. Main Outcome Measures. Glycemic screening, control and management strategies, documentation and counselling for lifestyle habits, prevalence of comorbidities, screening for hypertension, hyperlipidemia, and use of appropriate recommended preventive medications in the charts were examined. Results. Mean A1c was within target (less than or equal to 7.00) in 76% of patients (ICC = −0.02), at least 4 readings per annum were taken in 75% of patients (ICC = 0.006). Nearly 2/3 of patients had been counselled about diet, more than 1/2 on exercise, and nearly all (90%) were on medication. Nearly all patients had a documented blood pressure reading and lipid profile. Over half (60%) had a record of their weight and/or BMI. Conclusion. Although room for improvement exists, diabetes targets were mainly reached according to recognized best practices, in keeping with international data on attainment of diabetes targets.

ABSTRACT Objective: to determine the diagnosis of the situation regarding documentation of falls and risk of falls in people older than 75 years in basic health units in Spain and Portugal. Method: mixed exploratory study in two stages: (i) quantitative descriptive of randomly selected fall records produced in one year (597 records; 197 Spanish and 400 Portuguese); and (ii) qualitative, with the purpose of knowing the perception of health professionals employing semi-structured interviews (72 professionals, 16 Spanish and 56 Portuguese). The study areas were two basic health units in southern Spain and northern Portugal. Results: in the fall records, the number of women was higher. The presence of fall was associated with the variables age, presence of dementia, osteoarticular disease, previous falls and consumption of antivertiginous medication. Health professionals perceived an absence of risk assessment instruments, as well as lack of prevention programs and lack of awareness of this event. Conclusion: falls are perceived as an area of priority attention for health professionals. Nonetheless, there is a lack of adherence to the registration of falls and risk assessment, due to organizational, logistical and motivational problems.

This study aimed to estimate the exposure and related health risks of phthalates, and to assess the health risks from combined exposure to three of the phthalates sharing the same mode of action (anti-androgenicity) in children. We determined the internal exposure of 56 Iranian children and adolescents aged 6 to 18 years by analyzing seven urinary metabolites of five phthalates. The estimated daily intake values derived from the biomonitoring data ranged from 0.01 µg/kg bw/day for butyl benzyl phthalate (BBP), to 17.85 µg/kg bw/day for di(2-ethylhexyl) phthalate (DEHP). The risk assessment revealed that not only the exposure to the individual phthalates, but also the combined exposure to the three anti-androgenic phthalates (DEHP, DBP, BBP) did not raise a safety concern (hazard index values averaged 0.2). The range of maximum cumulative ratio values varied from around 1 for most individuals to around 2 in some individuals, indicating that the combined exposures were dominated by one and in some cases by two of the three anti-androgenic phthalates, especially dibutyl phthalate (DBP) and/or DEHP. Based on biomonitoring data, the overall combined exposure of Iranian children to phthalates does not raise a concern, while reduction of exposure is best focused on DEHP and DBP that showed the highest hazard quotient.
