RESUMO
Objective: To evaluate Di Cavalcanti's artworks in which goiters are represented before and after the introduction of iodized salt to the Brazilian population. Methods: One hundred and thirty paintings by Di Cavalcanti from the 20's to 70's demonstrating necks were evaluated. All the paintings were observed in reproductions. The neck circumference in the paintings was measured. Since there were no standard thresholds of neck circumference, cutoffs were based on the median. Baseline characteristics of artworks were compared based on high and normal neck circumference categories using Student's t-test, Mann-Whitney-Wilcoxon test, or chi square test. Results: We analyzed 29 artworks which portray the neck of 60 women (84.5%), 8 men (11.3%) and 3 children (4.2%). The analyses of the neck circumference showed 23.3% of women (14/60), 12.5% of men (1/8), and 33.3% of children (1/3) with an abnormal profile of the neck circumference. The neck circumference ratio in 29 paintings showed that the relative sizes of the necks painted between the 1920's and 1950's (r=0.45; p=0.03), and painted between the 1960's and 70's (r= 0.54; p=0.003) have linearly decreased. The decades in which the artworks were painted explained 40.0% of the variation in size of the neck circumference (p=0.002). Conclusion: Art imitates life. Di Cavalcanti was not a physician, and probably did not have the intention to illustrate a pathological condition, although the images observed in this study should be considered as goiter or enlarged neck.
Objetivo: Avaliar as obras de Di Cavalcanti em que bócios estão representados, antes e após a introdução da iodação do sal para a população brasileira. Método: Foram avaliadas 130 pinturas de Di Cavalcanti entre os anos 1920 e 1970 demonstrando pescoços. Todas as pinturas foram observadas em reproduções. A circunferência do pescoço nas pinturas foi mensurada. Como não existia limite-padrão da circunferência do pescoço, os limites foram baseados na mediana. As características básicas das obras de arte foram comparadas por categorias da circunferência do pescoço em elevadas e normais, usando o teste t de Student, o teste de Mann-Whitney-Wilcoxon ou o teste qui-quadrado. Resultados: Analisamos 29 obras de arte que representavam o pescoço de 60 mulheres (84,5%), 8 homens (11,3%) e 3 crianças (4,2%). Ao analisar a circunferência do pescoço, 23,3% das mulheres (14/60), 12,5% dos homens (1/8) e 33,3% das crianças (1/3) demonstraram perfil anormal dela. A relação da circunferência do pescoço em 29 pinturas demonstrou que as circunferências do pescoço relativas aos pescoços pintados entre os anos 1920 e 1950 (r=0,45; p=0,03) e pintados entre os anos 1960 e 1970 (r=0,54; p=0,003) reduziram linearmente. As décadas em que as obra foram pintadas explicaram 40,0% da variação no tamanho da circunferência do pescoço (p=0,002). Conclusão: A arte imita a vida. Di Cavalcanti não era médico e, provavelmente, não tinha intenção de ilustrar uma condição patológica, embora as observações das imagens, neste estudo, tenham sido consideradas como bócio ou com aumento de volume do pescoço

Although in modern societies fermented beverages are associated with socializing, celebration, and ritual, in ancient times they were also importa`nt sources of essential nutrients and potable water. In Mesoamerica, pulque, an alcoholic beverage produced from the fermented sap of several species of maguey plants (Agavaceae; Fig. 1) is hypothesized to have been used as a dietary supplement and risk-buffering food in ancient Teotihuacan (150 B.C. to A.D. 650). Although direct archaeological evidence of pulque production is lacking, organic residue analysis of pottery vessels offers a new avenue of investigation. However, the chemical components of alcoholic beverages are water-soluble, greatly limiting their survival over archaeological timescales compared with hydrophobic lipids widely preserved in food residues. Hence, we apply a novel lipid biomarker approach that considers detection of bacteriohopanoids derived from the ethanol-producing bacterium Zymomonas mobilis for identifying pulque production/consumption in pottery vessels. Gas chromatography-mass spectrometry selected ion monitoring (m/z 191) of lipid extracts of >300 potsherds revealed characteristic bacteriohopanoid distributions in a subset of 14 potsherds. This hopanoid biomarker approach offers a new means of identifying commonly occurring bacterially fermented alcoholic beverages worldwide, including palm wine, beer, cider, perry, and other plant sap- or fruit-derived beverages [Swings J, De Ley J (1977) Bacteriol Rev 41(1):1-46].

The US Food and Drug Administration (FDA) has recently warned consumers about the risks of weight loss supplements adulterated with multiple pharmaceutical agents. Some of these supplements combine potent anorectics, such as amphetamines derivatives, with benzodiazepines, beta-blockers, and other medications to suppress the anorectics' adverse effects. These weight loss supplements represent the most recent generation of rainbow diet pills, named for their bright and varied colors, which date back more than 70 years. Beginning in the 1940s, several US pharmaceutical firms aggressively promoted rainbow pills to physicians and patients. By the 1960s the pills had caused dozens of deaths before the FDA began removing them from the US market. We used a variety of original resources to trace these deadly pills from their origins in the United States to their popularity in Spain and Brazil to their reintroduction to the United States as weight loss dietary supplements.

Our purpose in this article is to describe the objectives, design, overall coverage, and main domains of data collection of the Institute of Nutrition of Central America and Panama Oriente Longitudinal Study and subsequent follow-up studies. This supplementary feeding trial targeted to pregnant and lactating women and children from birth to 7 y of age, conducted in 4 rural Guatemalan villages (1969-77) with a series of follow-up studies (1988-2007), is one of the richest sources of information on the effects of nutrition, growth, development, and human capital in the developing world, with outstanding data from gestation to adult age and 40 y of follow-up. Its results have influenced nutrition knowledge and policy with over 300 scientific publications. We present brief descriptions of preliminary studies that were critical for the success of the trial and the design and methods used during the trial and in the follow-up studies, in chronological order.
