In this study, pneumonia was induced in Balb/c mice using different concentrations of <i>S. aureus</i> to evaluate histopathological changes and progression with increasing concentrations of colony forming units (CFUs) as well as their interactions with inflammatory and cell death markers. Hematoxylin and eosin histological techniques and peroxidase immunohistochemistry were utilized to investigate outcomes that included edema and disruption of the bronchiole and blood vessel walls. Alveolar collapse and bronchiolar hyperplasia were also analyzed and were statistically significant, but only hyperplasia varied between the two groups that received intermediate concentrations of CFU (10<sup>7</sup> and 10<sup>8</sup>, respectively) to induce pneumonia. In the immunohistochemical analysis, progression of apoptosis was observed in groups that received up to 10<sup>8</sup> CFU, along with a probable predominance of autophagy and reduction in IL-6 in the group that received the highest concentration (10<sup>9</sup> CFU). These characteristics appear to indicate an attempt to preserve and reuse cells when high CFU concentrations are present and eliminate infected cells at lower concentrations.

The research was conducted on 18 human fetal pancreases obtained from spontaneous abortions or stillbirths between 17 to 36 weeks of gestation, categorized into normal (n=10) and anaemic (n=8) maternal groups. Results revealed a larger islet diameter in fetuses from anaemic mothers compared to the non-anaemic group (<i>P</i>=0.039). The beta cell percentage was significantly lower in the anaemic group across all gestational ages (<i>P</i>=0.003), while the alpha cell proportion remained unchanged in the anaemic group but increased significantly in the non-anaemic group after 20 weeks (<i>P</i>=0.006). The non-alpha/beta cell proportion in anaemic group was consistently higher than in the non-anaemic group. In conclusion, maternal anaemia results in the reprogramming of fetal pancreatic islets, characterized by a reduction in beta cell proportion, an increase in non-alpha/beta cells, and a disruption in the alpha-to-beta cell ratio. These changes may impair fetal pancreatic function and predispose the offspring to glucose intolerance and diabetes in later life.
