Covariation between the shape and mineralized tissues of the rib cross section in Homo sapiens, Pan troglodytes and Sts 14. AMERICAN JOURNAL OF BIOLOGICAL ANTHROPOLOGY 2024; 183:157-164.

Abstract
OBJECTIVES Studying rib torsion is crucial for understanding the evolution of the hominid ribcage. Interestingly, there are variables of the rib cross section that could be associated with rib torsion and, consequently, with the morphology of the thorax. The aim of this research is to conduct a comparative study of the shape and mineralized tissues of the rib cross section in different hominids to test for significant differences and, if possible, associate them to different thoracic morphotypes. MATERIALS AND METHODS The sample consists of the rib cross sections at the midshaft taken from 10 Homo sapiens and 10 Pan troglodytes adult individuals, as well as from A. africanus Sts 14. The shape of these rib cross sections was quantified using geometric morphometrics, while the mineralized tissues were evaluated using the compartmentalization index. Subsequently, covariation between both parameters was tested by a Spearman's ρ test, a permutation test and a linear regression. RESULTS Generally, P. troglodytes individuals exhibit rib cross sections that are rounder and more mineralized compared to those of H. sapiens. However, the covariation between both parameters was only observed in typical ribs (levels 3-10). Although covariation was not found in the rib cross sections of Sts 14, their parameters are closer to P. troglodytes. DISCUSSION On the one hand, the differences observed in the rib cross sections between H. sapiens and P. troglodytes might be related to different degrees of rib torsion and, consequently, to different thoracic 3D configurations. These findings can be functionally explained by considering their distinct modes of breathing and locomotion. On the other hand, although the rib cross sections belonging to Sts 14 are more similar to those of P. troglodytes, previous publications determined that their overall morphology is closer to modern humans. This discrepancy could reflect a diversity of post-cranial adaptations in Australopithecus.

Influence of different body positions in vital capacity in patients on postoperative upper abdominal. Braz J Anesthesiol 2015; 65:217-21. [PMID: 25925035 DOI: 10.1016/j.bjane.2014.06.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2014] [Accepted: 06/02/2014] [Indexed: 11/21/2022] Open
Abstract
RATIONALE The changes in body position can cause changes in lung function, and it is necessary to understand them, especially in the postoperative upper abdominal surgery, since these patients are susceptible to postoperative pulmonary complications. OBJECTIVE To assess the vital capacity in the supine position (head at 0° and 45°), sitting and standing positions in patients in the postoperative upper abdominal surgery. METHODS A cross-sectional study conducted between August 2008 and January 2009 in a hospital in Salvador/BA. The instrument used to measure vital capacity was analogic spirometer, the choice of the sequence of positions followed a random order obtained from the draw of the four positions. Secondary data were collected from the medical records of each patient. RESULTS The sample consisted of 30 subjects with a mean age of 45.2 ± 11.2 years, BMI 20.2 ± 1.0 kg/m(2). The position on orthostasis showed higher values of vital capacity regarding standing (mean change: 0.15 ± 0.03 L; p=0.001), the supine to 45 (average difference: 0.32 ± 0.04 L; p = 0.001) and 0° (0.50 ± 0.05 L; p = 0.001). There was a positive trend between the values of forced vital capacity supine to upright posture (1.68 ± 0.47; 1.86 ± 0.48; 2.02 ± 0.48 and 2.18 ± 0.52 L; respectively). CONCLUSION Body position affects the values of vital capacity in patients in the postoperative upper abdominal surgery, increasing in postures where the chest is vertical.

Abstract
INTRODUÇÃO: Os efeitos da postura sobre a função respiratória têm motivado pesquisas com o objetivo de rastrear alterações nos mecanismos de adaptação à mudança da postura corporal. A importância desse conhecimento está em compreender como essas alterações podem interferir na função respiratória de indivíduos saudáveis e em condições especiais, como obesos e gestantes. OBJETIVO: Realizar uma revisão bibliográfica para descrever o conhecimento produzido sobre as alterações da função respiratória em diferentes posturas corporais, em especial na postura sentada. MÉTODOS: Foram definidos os conceitos-chave da pesquisa: postura, postura sentada, testes respiratórios e função respiratória ou pulmonar; em seguida determinou-se o período de pesquisa que envolveu os anos de 2000 a 2010 (inclusive) e as bases de dados pesquisadas: SciELO, PEDro, Cochrane e Pubmed. RESULTADO: Encontrou-se que as primeiras pesquisas sobre função respiratória enfocavam alterações encontradas em mudanças significativas da postura corporal, geralmente em indivíduos saudáveis. O aprimoramento científico permitiu a incorporação tecnológica aos métodos de avaliação da função respiratória. Nos estudos sobre postura sentada, observa-se que as alterações são significativas em indivíduos com doenças pulmonares, cardíacas e idosos, entre outros, e que, mesmo em indivíduos saudáveis, as alterações nos testes de função podem ultrapassar a variação dos valores considerados normais para uma dada posição. CONCLUSÃO: São necessários maiores estudos para determinar o momento em que essas alterações podem ser significativas em indivíduos saudáveis e quais as alternativas possíveis para minimizar esses efeitos.
