[HPV genotypes prevalence in México and worldwide detected by Linear Array]

Infection with human papillomavirus (HPV) is the main factor associated with the development of cervical cancer (CC). Knowing about the prevalence of HPVs at different stages in the development of CC is important for determining the HPV oncogenic risk, the development of screening strategies, the evaluation of prevention programs, and also for vaccine designing. This paper is a meta-analysis of HPV prevalence worldwide and in Mexico from studies using the Linear Array® HPV Genotyping Test as a diagnostic test (it is the commercial test that, up to date, identifies the largest number of HPV genotypes in a single sample) in DNA of cervical samples from women with normal cytology, with low grade squamous intraepithelial lesions (LGSIL), with high grade squamous intraepithelial lesions (HGSIL) and with CC. The most prevalent genotypes after HPV-16 and -18 in women with CC varies depending on geographic region, which supports the need to develop detection and prevention strategies according to the characteristics of the population.

[Nutritional indicators in children with acute lymphoblastic leukemia]

BACKGROUND

A nutritional assessment allows to determine the state of nutrition and to predict the possibility of displaying additional risks for a disease. Previous investigations have verified that it is not sufficient for children with acute lymphoblastic leukemia (ALL) to have registry of anthropometric measurements such as age, weight, and height. Given the previous information, it is necessary to conduct studies with nutritional indicators that contribute to understanding their importance in children with ALL.

OBJECTIVE

To compare the nutritional values of five indicators of children with and without ALL.

METHODS

A sample of 21 children with a diagnosis of ALL and 54 children without ALL (control) participated in the study; the children's ages ranged between 1.3 to 10 years. Comparisons between cases and controls were performed.

RESULTS

Indicators of albumin and triceps skin fold showed differences between the groups (p < 0.005).

CONCLUSIONS

Children with ALL at time of diagnosis had nutritional deficiencies of subcutaneous fat reserve and protein. These indicators could be part of the prognostic and standard of care for children with this cancer.
