Infant malnutrition, development rate and its relation to the environment: a pilot study Desnutrición infantil, coeficiente de desarrollo y su relación con el medio ambiente: un estudio piloto.

The socio-cultural factors that might be influencing the normal psychomotor development of the undernourished infant are studied. The sample consisted of 32 mother-infant dyads: 16 having normal DQ (Group A) and 16 having a below normal DQ (Group B) according to Bailey's Test applied to infants who entered a Nutritional Recuperation Center. Results showed that there were some differences in the infants' backgrounds: infants of Group A were the product of a wished-for pregnancy (p less than .05), and were separated less from their mother's side (p less than .007) than was the case in Group B. No differences were found in the socio-cultural and demographic background of the mothers. The infants' external environment was different in aspects observed within the neighborhood: there were fewer negative aspects in Group A than in Group B (p less than .003) and more positive in Group A than in B (p less than .001). The infant's internal environment as related to the mother was also different

Psychometric Properties of the Peruvian Version of the MOS Scale for Social Support in Cancer Patients and Convergent Network with Quality of Life

While much research has been conducted on the role of social support in the lives of cancer patients, there is a lack of studies that consider populations who need specific tools to assess this concept.Purpose: The aim of this study was to evaluate the psychometric properties of the MOS Social Support Scale (1991) in 499 Peruvian cancer patients between the ages of 18 and 87 (M= 46.30, SD = 15.747).Methods: In this study, three models of the MOS were analyzed based on 19-item versions (four factor, second order and bifactor model).Results: The results showed a better psychometric fit in the 19-item bifactor model with optimal fit indices through the structural equation method (SB-χ 2/df = 1.94, CFI = 0.966, TLI= 0.955, SRMR = 0.038 and RMSEA = 0.058). Additionally, there was evidence of configural, metric and scalar invariance with this instrument according to the gender of the surveyed cancer patients. Convergent validity using a network analysis approach revealed positive associations between social support dimensions and quality of life.Conclusion: Emotional support and positive interactions dimensions were found to be important interconnections in the overall network, as indicated by their greater centralities. Therefore, this instrument could be suggested as a reliable way to evaluate cancer patients and their perceived support.Keywords: social support, factor invariance, oncology, cancer, network analysi

The insecticidal, molting disruption and insect growth inhibitory activity of extracts from Condalia microphylla Cav. (Rhamnaceae)

Extracts obtained from a common shrub that occurs as part of vegetative species growing on arid lands of North-Central Chile and adjacent central Argentina known as “piquilin” Condalia microphylla (Rhamnaceae) showed insect growth inhibitory activity against the fall armyworm Spodoptera frugiperda, yellow meal worm Tenebrio molitor and fruit fly Drosophila melanogaster larvae in artificial diet feeding assays. The effects of these extracts on mortality, antifeedancy and growth inhibition were examined. The phytochemical profile of the most active extract was examined with conventional chromatographic and spectroscopic procedures. This n-hexane extract showed a high percentage of hentriacontane and triacontane. The observed mortality strongly correlates with the contents of these long-chain n-alkanes compounds, the LD50 for n-hexane, ethyl acetate and methanol extracts against S. frugiperda, were 3.89, 9.4, and 9.7 ppm; against T. molitor 5.2, 14.2, and 20.4 ppm, and against D. melanogaster 3.23, 7.65 and 17.9 ppm, respectively.Fil: Cespedes, Carlos L..
