RESUMO
Marine teleost species of commercial interest are often reported with hyperostosis, an osteological condition that results in bone thickening. Various specimens of Atlantic Spadefish Chaetodipterus faber (n = 86) obtained from artisanal fishermen in Rio de Janeiro, Brazil, were radiographed and assessed to detect the occurrence of hyperostosis across four different size classes. Of the examined individuals, 58.62% displayed signs of hyperostosis, which manifested in eight skeletal regions, notably in the supraoccipital crest, cleithrum and supraneural areas. In the vertebral column, hyperostosis was more frequently observed in haemal spines than in neural spines, predominantly between the sixth and eighth caudal vertebrae. The smallest size class (<200 mm total length) showed a low frequency of hyperostosis at 7.89%. This frequency escalated for larger classes, reaching 94.12% in individuals measuring 200-300 mm in total length and was observed in all individuals exceeding 300 mm. Hyperostosis exhibited an ontogenetic development pattern, where both the occurrence frequencies and the sizes of the affected bones expanded in proportion to the fish size. This is the first description of the hyperostosis pattern of development for the species, an important commercial resource.

OBJECTIVES: Cribra orbitalia (CO) and porotic hyperostosis (PH) are porous cranial lesions (PCLs) classically associated with iron-deficiency anemia in bioarchaeological contexts. However, recent studies indicate a need to reassess the interpretation of PCLs. This study addresses the potential health correlates of PCLs in a contemporary sample by examining relationships between the known cause of death (COD) and PCL presence/absence. METHODS: This study includes a sample of 461 juvenile individuals (6 months to 15 years of age) who underwent examination at the University of New Mexico's Office of the Medical Investigator between 2011 and 2019. The information available for each individual includes their sex, age at death, and their COD and manner of death. RESULTS: Odds ratio of having CO (OR = 3.92, p < .01) or PH (OR = 2.86, p = .02) lesions are increased in individuals with respiratory infections. Individuals with heart conditions have increased odds of having CO (OR = 3.52, p = .03) lesions, but not PH. CONCLUSION: Individuals with respiratory infection are more likely to have CO and/or PH. CO appears to have a greater range of health correlates than PH does, as indicated by the heart condition results. However, individuals with congenital heart defects are at higher risk for respiratory infections, so bony alterations in cases of heart conditions may be due to respiratory illness. Since respiratory infection remains a leading cause of mortality today, CO and PH in bioarchaeological contexts should be considered as potential indicators of respiratory infections in the past.

Cribra orbitalia is characterized by an aggregation of small apertures in the orbital roof in response to marrow hypertrophy. This pathological change is indicative of biological stress during youth. We examined the prevalence of this lesion in Pacopampa, a ceremonial center of the formative period, located in the northern highlands of Peru. Using this evaluation of cribra orbitalia, we reconstructed aspects of the population's health and nutritional status during the formation of Andean civilization. We examined 41 orbits of 27 adult individuals (13 males, 14 females) and recorded the macroscopic presence or absence of cribra orbitalia. The presence or absence of cribra orbitalia was the same bilaterally for all 14 individuals having both orbits preserved. The pathology was present in two of the 13 males (15.4%), one of the 14 (7.1%) females, and three of 27 individuals (11.1%) for both sexes combined. There was no difference in the frequency between sexes. The prevalence of cribra orbitalia was found to be lower in Pacopampa than in the comparative data of coastal populations. It is reasonable to assume that the increase in social complexity in Pacopampa was probably unrelated to the decline in overall health of the people.
