Blending interprofessional education and simulation learning: A mixed-methods study of an interprofessional learning experience with nursing and occupational therapy students.

In aiming to train health professional students to collaborate in patient care settings, the purpose of this study was to evaluate the perception of registered nurse (RN) students and occupational therapy (OT) students jointly participating in an interprofessional education (IPE) patient simulation learning experience. Eighty-five RN and OT students engaged in a 3-hour IPE patient simulation in an acute care hospital setting. Each student participant completed a pre- and post-test data collection, assessing interprofessional socialization using the Interprofessional Socialization and Valuing Scale (ISVS) Version 9A and provided qualitative feedback about their experience. Findings indicated a significant change in interprofessional socialization for RN and OT students after engaging in the IPE patient simulation learning experience. Furthermore, qualitative findings described the perceived benefits of IPE and collaboration, simulation as a learning tool, and areas for enhancing IPE patient simulation education for the future. Study findings have implications for using simulated IPE experiences with health professional students to foster interprofessional collaboration and socialization with the goal of delivering person-centered quality healthcare.

Variation in Middle Stone Age mandibular molar enamel-dentine junction topography at Klasies River Main Site assessed by diffeomorphic surface matching.

The morphology and variability of the Middle Stone Age (MSA) hominin fossils from Klasies River Main Site have been the focus of investigation for more than four decades. The mandibular remains have figured prominently in discussions relating to robusticity, size dimorphism, and symphyseal morphology. Variation in corpus size between the robust SAM-AP 6223 and the diminutive SAM-AP 6225 mandibles is particularly impressive, and the difference between the buccolingual diameters of their M2s significantly exceeds recent human sample variation. SAM-AP 6223 and SAM-AP 6225 are the only Klasies specimens with homologous teeth (M2 and M3) that permit comparisons of crown morphology. While the differences in dental trait expression at the outer enamel surfaces of these molars are slight, diffeomorphic surface analyses of their underlying enamel-dentine junction (EDJ) topographies reveal differences that are well beyond the means of pairwise differences among comparative samples of Later Stone Age (LSA) Khoesan and recent African homologues. The EDJs of both SAM-AP 6225 molars and the SAM-AP 6223 M3 fall outside the envelopes that define the morphospace of these two samples. Although the radiocarbon dated LSA individuals examined here differ by a maximum of some 7000 years, and the two Klasies jaws may differ by perhaps as much as 18,000 years, it is difficult to ascribe their differences to time alone. With reference to the morphoscopic traits by which the SAM-AP 6223 and SAM-AP 6225 EDJs differ, the most striking is the expression of the protoconid cingulum. This is very weakly developed on the SAM-AP 6223 molars and distinct in SAM-AP 6225. As such, this diminutive fossil exhibits a more pronounced manifestation of what is likely a plesiomorphic feature, thus adding to the morphological mosaicism that is evident in the Klasies hominin assemblage. Several possible explanations for the variation and mosaicism in this MSA sample are discussed.

Recognition and nursing management of diabetes in children.

Diabetes mellitus is a common condition in children, characterised by chronic hyperglycaemia resulting from an absolute insulin deficiency. It can present in various ways, and hospital admission may result from complications related to previously diagnosed diabetes, or from a new diagnosis. To raise awareness of the condition, Diabetes UK has launched the 4Ts campaign, which highlights the four most common symptoms of diabetes. This article discusses the different clinical presentations, diagnosis and management of children with diabetes, and includes two case studies to illustrate some of the challenges faced by emergency department nurses.

Microstratigraphic evidence of in situ fire in the Acheulean strata of Wonderwerk Cave, Northern Cape province, South Africa.

The ability to control fire was a crucial turning point in human evolution, but the question when hominins first developed this ability still remains. Here we show that micromorphological and Fourier transform infrared microspectroscopy (mFTIR) analyses of intact sediments at the site of Wonderwerk Cave, Northern Cape province, South Africa, provide unambiguous evidence--in the form of burned bone and ashed plant remains--that burning took place in the cave during the early Acheulean occupation, approximately 1.0 Ma. To the best of our knowledge, this is the earliest secure evidence for burning in an archaeological context.

Enamel pearls: Their occurrence in recent human populations and earliest manifestation in the modern human lineage.

OBJECTIVE: To document and describe the occurrence of an enamel pearl on the distal root surface of the maxillary M3 of the fossil hominin specimen from Florisbad, South Africa that is dated to ca. 259,000 years B.P., and is an early representative of Homo sapiens or as a member of the evolutionary line that was directly ancestral to modern humans. DESIGN: The molar was examined macroscopically and by micro-computed tomography (µCT) to enable accurate measurement and visualization of the structure of the enamel pearl. RESULTS: The single pearl has a diameter of 0.97 mm; it is a Type 2 "composite" pearl comprising an enamel cap and dentine core without pulp chamber involvement. The size of the Florisbad pearl falls within or just below the size ranges of this anomaly in modern human samples. Type 2 pearls are most commonly encountered in recent human populations, and the location of the pearl on the distal root surface of the Florisbad M3 is consistent with its most frequent location in recent humans. Pearls in recent human populations affect between 0.2-4.8% of individuals, and 1.7-6.8% of permanent molars. Pearls have been documented in several prehistoric human dentitions, and all examples are less than 4000 years old. CONCLUSIONS: Enamel pearls have been associated with periodontal disease, but it is not possible to relate its presence to the advanced periodontal inflammation and alveolar bone loss in the Florisbad fossil. Florisbad presents the earliest evidence of this anomaly in the fossil record pertaining to modern humans.
