There are few studies that classify and characterize the morphometric and immunohistochemical features of goitre in bovine thyroid glands (TGs). We investigated 39 bovine TGs (fetuses [9], stillbirths [18], neonates [12]) born to dams with low T4 hormone levels and no iodine supplementation and 10 (fetuses [3], stillbirths [3], neonates [4]) born to dams with normal T4 levels and supplemented with iodine. Body weight (BW), TG weight (TGW), TGW:BW ratio and histological lesions were determined. The TGs were classified histopathologically as normal gland (G0), mild goitre (G1), moderate goitre (G2) or severe goitre (G3). Various morphological and morphometric parameters were calculated from microscopic images using image analysis software. Immunohistochemistry was performed to detect proliferating cell nuclear antigen (PCNA). There were significant differences in the TGW:BW ratio among groups (P <0.05): 0.3 ± 0.1 in G0, 0.5 ± 0.3 in G1, 0.8 ± 0.3 in G2 and 1.3 ± 0.7 in G3. In G0, large homogeneous follicles with eosinophilic colloid were seen. In the groups with lesions (G1, G2 and G3), heterogeneity in follicle shape and size, height and area of thyroid follicular cells, height of thyroid follicular epithelium and PCNA immunolabelling were directly related to histopathological grade, with significant differences among groups (P <0.001), gradually increasing from G1 to G3 compared with G0. The TGW:BW ratio and histological grade were positively correlated (P = 0.008). [Display omitted] [ABSTRACT FROM AUTHOR]

Background: Research indicated the prevalence of perinatal deaths of infants immediately or up to a week after birth and includes fresh and macerated stillbirths and neonatal deaths. Worldwide, there is a decline in perinatal deaths. However, in South Africa, it is not the case. Often the quality of maternity care is considered as the most important contributing factor for these deaths. However, maternal and neonatal factors can also contribute. Aim: The aim of the study was to determine the maternal and neonatal factors associated with perinatal deaths in a single selected district hospital within the Free State Province of South Africa. Setting: The maternity unit of the largest district hospital in the specific district in the Free State Province of South Africa. Method: A clinical audit design was used. Units of analysis comprised the Perinatal Problem Identification Programme (PPIP) database of neonates born during 2015, and their mothers. A random sample of 384 alive neonates and an all-inclusive sample of 43 deceased neonates were taken from a total of 2319. Descriptive statistics were reported and Cohen's effect sizes, d, were calculated to identify practically significant differences between the neonates in the alive and the deceased group, respectively. Results: Cohen's effect sizes and logistical regression analyses indicate that the Apgar score recorded 10 min after birth, gestational age, birth weight of neonate and the parity of the mother were the most practically significant factors influencing a neonate's chances of survival. Conclusion: Quality maternity care is not the only cause of perinatal mortality rates; maternal and neonatal factors are also contributors. [ABSTRACT FROM AUTHOR]

Background: External inquiries are carried out following adverse maternal/perinatal events, to examine the care provided and make recommendations to improve it. Clinical governance ensures that organisations promote high-quality care and are accountable for the care they provide, thus contributing to its improvement. Objective: This study examined how Irish perinatal bereavement services and the management of perinatal deaths (including events leading up to the deaths) were affected by developments in maternity services governance as described in ten Irish enquiry reports published over 14 years (2005–18). Methods: Two clinicians collected data from the ten enquiry reports by using a specifically designed review tool. Thematic analysis was carried out, following the steps of familiarising, coding, identifying, grouping and revising themes. Findings: Seven main themes were identified: workforce, leadership, management of risk, work environment, hospital oversight, national documents, data collection. Eight reports noted shortcomings in staffing levels, with a workforce that was under-resourced, and at times carried excessive workloads. The absence of 24/7 midwifery-shift leaders in maternity units resulted in problems with care at times not being escalated appropriately. The absence of a widely-owned, understood strategic plan for the management of the maternity services was mentioned in the reports from 2013. Conclusions and implications for practice The National Bereavement Care Standards were published in 2016 to address deficiencies identified in the enquiry reports and to standardise perinatal bereavement care across Irish maternity units. Though the first Irish Maternity Strategy (2016–26) was published in 2016, its implementation is incomplete. Inconsistencies remain in the definition and collection of national perinatal data, as well as concerns regarding the lack of local audit activities on pregnancy outcomes. Greater focus on hospital oversight, implementation of national documents and reliable data collection is required. To be effective and initiate positive changes in clinical services, documents such as incident reviews, national strategies and national reports including inquiries, need to include realistic recommendations with clear timelines and responsibilities for implementation.
