Early Archaic human skeletal remains found in a burial context in Lapa do Santo in east-central Brazil provide a rare glimpse into the lives of hunter-gatherer communities in South America, including their rituals for dealing with the dead. These included the reduction of the body by means of mutilation, defleshing, tooth removal, exposure to fire and possibly cannibalism, followed by the secondary burial of the remains according to strict rules. In a later period, pits were filled with disarticulated bones of a single individual without signs of body manipulation, demonstrating that the region was inhabited by dynamic groups in constant transformation over a period of centuries.

Undernutrition is a stressor with long-term consequences, and the effect of nutritional recovery on cortisol and thyroid hormone status is unknown. To investigate basal thyroid hormones and the cortisol response to a cold pressor test in children recovered from undernutrition, a cross-sectional study was undertaken on children (6–16 years) separated into four groups: control (n 41), stunted (n 31), underweight (n 27) and recovered (n 31). Salivary cortisol was collected over the course of 10 h: upon awakening, before and after an unpleasant and a pleasant stimulus. Cortisol upon awakening was highest in the stunted and lowest in the underweight groups: control=5·05 (95 % CI 3·71, 6·89) nmol/l, stunted=6·62 (95 % CI 3·97, 11·02) nmol/l, underweight=2·51 (95 % CI 1·75, 3·63) nmol/l and recovered=3·46 (95 % CI 2·46, 4·90) nmol/l (P=0·005). Girls had higher cortisol concentrations upon awakening compared with boys (P=0·021). The undernourished groups showed an elevated cortisol response both to the unpleasant stimulus and at the last measurement (16.00 hours) compared with that of the recovered group: AUC, control=2·07 (95 % CI 1·69, 2·45) nmol/l×30 min, stunted=2·48 (95 % CI 1·91, 3·06) nmol/l×30 min, underweight=2·52 (95 % CI 2·07, 2·97) nmol/l×30 min, recovered=1·68 (95 % CI 1·26, 2·11) nmol/l×30 min (P=0·042); and control=2·03 (95 % CI 1·75, 2·39) nmol/l×30 min, stunted=2·51 (95 % CI 1·97, 3·19) nmol/l×30 min, underweight=2·61 (95 % CI 2·16, 3·16) nmol/l×30 min, recovered=1·70 (95 % CI 1·42, 2·03) nmol/l×30 min (P=0·009). Lower free thyroxine (T4) was found in the recovered and stunted groups: control=1·28 (95 % CI 1·18, 1·39) pmol/l, stunted=0·98 (95 % CI 0·87, 1·10) pmol/l, underweight=1·10 (95 % CI 1·01, 1·21) pmol/l and recovered=0·90 (95 % CI 0·83, 0·99) pmol/l (P<0·001). Multivariate analysis showed a lower cortisol concentration along 10 h (06.00–16.00 hours) in the recovered compared with the other groups (P=0·017), and similar concentrations between the recovered and control group. In conclusion, the children with recovery in weight and height had a cortisol stress response similar to control but a lower basal free T4. Longitudinal studies are warranted to determine the extent of these endocrine changes after recovery of undernutrition and in adulthood.
