The risk–benefit ratio for concurrent use of dietary antioxidants with chemotherapy or radiation therapy is a controversial topic. In this review, the medical literature on concurrent antioxidant use with chemotherapy or radiotherapy was assessed and further steps for generating evidence-based guidelines are suggested. The clinical cancer research community should cooperate and focus new studies on the use of a specific combination of antioxidant and chemotherapy or radiotherapy, and determine optimal doses for a specific cancer setting. Mechanistic studies on the interaction between antioxidants and conventional cancer therapy could lead to novel biomarkers for assessing dose adequacy.

IntroductionSeveral factors including the parental literacy, illness, socioeconomic status, poor sanitation and hygienic practices affect the physical growth of children. The aim of this study was to determine the socio-demographic determinants of malnutrition among primary school aged children in Enugu, Nigeria.MethodsA cross-sectional descriptive study involving primary school children in Enugu was carried out over a 3 month period. Subjects were selected using multistage sampling technique. Weight and height were measured using a digital scale and a wooden stadiometer, respectively. Body Mass Index (BMI), weight-for-age (WAZ), Height-for-age (HAZ) and BMI-for-age z scores were then derived using the new WHO reference standards.Results348 children (40.4%) were recruited from 5 public schools while 512 (59.6%) were recruited from 9 private schools. The mean age of the study participants was 9.2 ± 1.8 years. 7 (0.8%) children were stunted, 26 (3.3%) wasted and 28 (3.3%) underweight. Of all the study participants, overweight and obesity were observed in 73 (8.5%) and 35 (4.1%) children, respectively. Children of lower socioeconomic class were more stunted, underweight and wasted, while overweight and obesity were more prevalent among children from the upper socioeconomic class.ConclusionFactors such as age and sex, parental education and socioeconomic class had a significant impact on nutritional status. Overweight and obesity were more prevalent among the children from the upper socioeconomic class, attending private schools, while stunting and wasting were more in children of the lower class attending public schools.

BackgroundDetermination of weight in children is an important aspect of their assessment. It has a wide range of usefulness including assessing their nutritional status and drug dose calculation. Despite its usefulness, weight estimation in children in certain conditions can be challenging particularly in emergency situations or in children who are severely ill or cannot stand on standard scales. The Broselow Tape which is a validated tape that is used to estimate weight based on length was developed using height/weight correlations from Western data. However, considering the variations in anthropometric measurements of children from different geographic locations, there is need to ascertain how accurate it is to estimate weight using the Broselow tape among children in Nigeria.AimThe study was carried out to determine the accuracy in the use of the Broselow Tape in weight estimation among Nigerian children.MethodA total 1456 children aged 1–12 years who satisfied the inclusion criteria were enrolled over a 2½ year period from two tertiary health facilities in Enugu state Nigeria. Weight was taken using standard weighing scale and Broselow tape. Data collected was analysed using SPSS.ResultOf the 1456 children studied, majority (84.2%) had normal Body-Mass-Index (BMI) while about 4.6% had a low BMI percentile for age. The mean weight difference between the two methods was not significantly different between the 1 to 6 years old category. Significant differences were observed from 7 up to 12 years. The Broselow Tape overestimated weights in 1 year old by 3.88%, 2 years 1.58%, 3 years by 2.13%, 4 years (1.94%) and 5 year (0.07%). After 5 years, the degree of overestimation rises sharply to 4.25% in 6, 9.25% in 7, 7.29% in 8 and 9.29%. 9.18, 11.61% & 6.75% in 9, 10, 11 and 12 years old respectively. The proportion of estimated weights that was within 10- 20% of the actual weight was higher in the 1-6 years age categories compared to weight estimates in older age categories.ConclusionWeight estimates obtained using the Broselow tape correlated better in children that are 6 years or younger compared to those in the older age categories. There is need for re-validation and/or adjustments of the Broselow tape especially in children over 6 years old.
