Music as a determinant of health among First Nations people in Australia: A scoping narrative review.

ISSUE ADDRESSED: While social determinants frameworks are still popular in research about First Nations health in Australia, a growing body of research prefers cultural determinants of health models. Cultural determinants models provide a holistic, strength-based framework to explain connections between health and contextual factors, including the potential role of music and its impact on social and emotional well-being. Given the growing international recognition of links between music, health, and wellbeing through bodies such as the World Health Organisation, this article examines whether and how music practices are acknowledged in First Nations determinants of health literature. METHODS: We conducted a scoping narrative review of literature from five databases: Scopus, PsycInfo, CINAHL, PubMed and ProQuest Central. The search returned 60 articles published since 2017, which we analysed in NVivo for common themes. RESULTS: Music was only explicitly identified as a determinant of health in two studies. Yet, participants in five studies identified music and song as directly impacting their social and emotional well-being. When we broadened our frame of analysis to include other forms of expressive cultural practice, one quarter of included studies empirically acknowledged the role of expressive cultural practice for social and emotional well-being. CONCLUSION: While many recent studies identify the impact of First Nations' expressive practices broadly, they miss important features of First Nations music as a potentially unique cultural, social, political and ecological determinant of health. SO WHAT?: There is an opportunity for future research and health determinant modelling to explicitly examine the role of First Nations music and other creative practices for social and emotional well-being.

First Nations music as a determinant of health in Australia and Vanuatu: political and economic determinants.

This article reports on findings that indicate how First Nations musical activities function as cultural determinants of health. Drawing on early findings from a 3-year Australian Research Council funded project titled The Remedy Project: First Nations Music as a Determinant of Health, we detail Australian and Ni Vanuatu First Nations musicians' reported outcomes of musical activity using a First Nations cultural determinants of health framework. The broader findings indicate that our respondents see musical activity as actively shaping all known domains of cultural health determinants, and some surrounding political and social determinants. However, this paper focusses specifically on the political and economic determinants that emerged in analysis as the most dominant subthemes. We argue that this study provides strong impetus for continued investigation and reconceptualization of the place of music in cultural health determinant models.

This article looks at how making and performing music, recording music and listening to music helps the health of First Nations peoples in Australia and Ni Vanuatu. Music is an important part of the lives of First Nations peoples from these places and so research was done to try to understand why it is meaningful. Music can be used as an outlet for personal feelings, and can also be a way that groups of people can express common concerns. First Nations musicians talked about how music makes them feel, and how music is used to strengthen relationships between people, and between people and their culture. Musicians also talked about how music helps them express their political and economic goals. The findings backed up existing First Nations' models of health that say that health for First Nations People's needs to be thought about in a holistic way. The findings also showed that the relationship between music and health needs to be studied more so that we can better understand how it helps maintain links with the past, gives a guide for the present and opens options for the future.

Multiligamentous Injury of the Knee: MRI Diagnosis and Injury Patterns.

Anterior cruciate and posterior cruciate injuries rarely occur in isolation and are often associated with injuries to the secondary or supporting structures that provide stability against rotational forces. These structures include the posterolateral and posteromedial corner ligaments and tendons, as well as the anterolateral ligament. If injuries to these secondary structures are not appreciated at the time of cruciate ligament reconstruction, an isolated cruciate ligament reconstruction may be predisposed to early failure. Thus it is crucial for radiologists interpreting knee magnetic resonance imaging to understand and report on injury to these ligaments and tendons at the time of initial injury to help the orthopaedic surgeon plan a comprehensive approach to ligament reconstruction. This strategy will ultimately result in improved patient outcomes.

From tumor to trauma: etiologically deconstructing a unique differential diagnosis of musculoskeletal entities with high signal intensity on T1-weighted MRI.

OBJECTIVE: This article reviews the neoplastic and nonneoplastic abnormalities of the musculoskeletal system that contain high signal intensity on T1-weighted MRI. The physical properties accounting for the increased signal intensity as well as the key clinical and imaging characteristics of each entity are discussed. CONCLUSION: Recognition of high signal intensity within musculoskeletal lesions on T1-weighted MRI can limit the differential diagnosis and can also have important clinical implications.

Osteoma of long bone: an expanding spectrum of imaging findings.

Osteoma of long bone is an extremely rare, benign bone-forming surface lesion with the largest published case series consisting of only 14 patients. The most important and often most difficult lesion to differentiate from osteoma of long bone radiographically is parosteal osteosarcoma, which is a rare, low-grade surface osteosarcoma with the potential for dedifferentiation. Reports of imaging studies of osteoma of long bone depict a well-defined ossified mass arising from the surface of the diaphysis or metadiaphysis of a long bone. A characteristic feature is the homogeneity of the mass, with uniform density near or equal to that of cortical bone from the base of the lesion to its periphery. The 45-year-old female in this case presented with left hip fullness and was subsequently found to have a proximal femoral osteoma, which was unique in that it contained large fatty marrow spaces that corresponded to bands of relatively low density on plain radiography and computed tomography, giving it a heterogeneous appearance atypical of osteoma of long bone. Furthermore, the osteoma reported here was associated with a small but separate nodular focus of ossification in the adjacent soft tissue. These findings led to a presumptive diagnosis of parosteal osteosarcoma with a local soft tissue metastasis or satellite nodule resulting in radical resection of the tumor. Definitive diagnosis of osteoma was made on histology of both the parent lesion and ossified nodule as no neoplastic spindle cell proliferation was present to establish a diagnosis of low-grade osteosarcoma. This represents, to the best of our knowledge, the first such presentation of osteoma of long bone.

Revisiting the central gland anatomy via MRI: does the central gland extend below the level of verumontanum?

PURPOSE: To determine whether the central gland of the prostate, composed of both central and transition zones, extends below the verumontanum in patients over age 43 based on prostate magnetic resonance imaging (MRI). MATERIALS AND METHODS: In all, 82 patients who underwent preoperative, multiparametric endorectal MRI (1.5T and 3T) at our institution were included. The central gland was defined as a combination of the central zone and transition zone. Two radiologists measured central gland extension below verumontanum using axial, coronal, and sagittal T2-weighted images and coregistration picture archiving and communication system software. RESULTS: The final cohort consisted of 63 patients with a mean age of 60.2 years (standard deviation: 7.1, range: 43-76). The central gland extended below the verumontanum in 60/63 (95%) patients. Mean central gland extension below the verumontanum was 6.5 mm (standard deviation = 3.7, range: 0, 18). Weak (r = 0.35), but significant (P = 0.005) positive correlation was found between age and the amount of central gland extension below the verumontanum. CONCLUSION: Contrary to McNeal's classical prostatic anatomy teaching, the central gland extends below the verumontanum in 95% of men over 43, likely due to deformation of the gland by benign prostatic hyperplasia. It is important for pathologists to be aware of this observation for accurate characterization of the zonal origin of prostate cancer below the level of the verumontanum.

Musculoskeletal aspiration procedures.

With advances in imaging technology, there has been a significant increase in the number and range of interventional musculoskeletal image-guided procedures. One of the most commonly performed image-guided musculoskeletal interventions is the diagnostic and therapeutic percutaneous aspiration and drainage of multiple types of intra-articular, juxta-articular, and intramuscular pathologic fluid collections. These procedures may be performed under fluoroscopic, ultrasound, computed tomography, or even magnetic resonance guidance depending on the location to be accessed, type of pathology, patient characteristics, and operator preference. Musculoskeletal image-guided aspiration and drainage procedures are minimally invasive and generally very safe while offering valuable diagnostic information as well as therapeutic benefit. This article focuses on the appropriate indications, contraindications, and general technique for accessing the major joints via imaging guidance. For each joint, we discuss pertinent anatomy, appropriate imaging modalities, and preferred approaches to gaining intra-articular access. Additionally, the article discusses some of the more frequently encountered juxta-articular and intramuscular fluid collections that can be accessed and aspirated via percutaneous intervention, with mention of the importance of recognizing extremity sarcomas that can mimic these benign collections.

Bioavailability of zinc and copper in biosolids compared to their soluble salts.

For essential elements, such as copper (Cu) and zinc (Zn), the bioavailability in biosolids is important from a nutrient release and a potential contamination perspective. Most ecotoxicity studies are done using metal salts and it has been argued that the bioavailability of metals in biosolids can be different to that of metal salts. We compared the bioavailability of Cu and Zn in biosolids with those of metal salts in the same soils using twelve Australian field trials. Three different measures of bioavailability were assessed: soil solution extraction, CaCl(2) extractable fractions and plant uptake. The results showed that bioavailability for Zn was similar in biosolid and salt treatments. For Cu, the results were inconclusive due to strong Cu homeostasis in plants and dissolved organic matter interference in extractable measures. We therefore recommend using isotope dilution methods to assess differences in Cu availability between biosolid and salt treatments.

Application of phytotoxicity data to a new Australian soil quality guideline framework for biosolids.

To protect terrestrial ecosystems and humans from contaminants many countries and jurisdictions have developed soil quality guidelines (SQGs). This study proposes a new framework to derive SQGs and guidelines for amended soils and uses a case study based on phytotoxicity data of copper (Cu) and zinc (Zn) from field studies to illustrate how the framework could be applied. The proposed framework uses normalisation relationships to account for the effects of soil properties on toxicity data followed by a species sensitivity distribution (SSD) method to calculate a soil added contaminant limit (soil ACL) for a standard soil. The normalisation equations are then used to calculate soil ACLs for other soils. A soil amendment availability factor (SAAF) is then calculated as the toxicity and bioavailability of pure contaminants and contaminants in amendments can be different. The SAAF is used to modify soil ACLs to ACLs for amended soils. The framework was then used to calculate soil ACLs for copper (Cu) and zinc (Zn). For soils with pH of 4-8 and OC content of 1-6%, the ACLs range from 8 mg/kg to 970 mg/kg added Cu. The SAAF for Cu was pH dependant and varied from 1.44 at pH 4 to 2.15 at pH 8. For soils with pH of 4-8 and OC content of 1-6%, the ACLs for amended soils range from 11 mg/kg to 2080 mg/kg added Cu. For soils with pH of 4-8 and a CEC from 5-60, the ACLs for Zn ranged from 21 to 1470 mg/kg added Zn. A SAAF of one was used for Zn as it concentrations in plant tissue and soil to water partitioning showed no difference between biosolids and soluble Zn salt treatments, indicating that Zn from biosolids and Zn salts are equally bioavailable to plants.

Models for the field-based toxicity of copper and zinc salts to wheat in 11 Australian soils and comparison to laboratory-based models.

Laboratory-based relationships that model the phytotoxicity of metals using soil properties have been developed. This paper presents the first field-based phytotoxicity relationships. Wheat (Triticum aestivum L.) was grown at 11 Australian field sites at which soil was spiked with copper (Cu) and zinc (Zn) salts. Toxicity was measured as inhibition of plant growth at 8 weeks and grain yield at harvest. The added Cu and Zn EC10 values for both endpoints ranged from approximately 3 to 4760 mg/kg. There were no relationships between field-based 8-week biomass and grain yield toxicity values for either metal. Cu toxicity was best modelled using pH and organic carbon content while Zn toxicity was best modelled using pH and the cation exchange capacity. The best relationships estimated toxicity within a factor of two of measured values. Laboratory-based phytotoxicity relationships could not accurately predict field-based phytotoxicity responses.

Modeling the toxicity of copper and zinc salts to wheat in 14 soils.

Interest is mounting in developing and utilizing soil-specific soil quality guidelines. This requires quantifying the effects that soil physicochemical properties have on various ecotoxicological endpoints, including phytotoxicity. To this end, 14 agricultural soils from Australia with differing soil properties were spiked with copper (Cu) and zinc (Zn) salts and used to conduct 21-d plant growth inhibition tests using wheat (Triticum aestivum L.) in pot trials. The toxicity of Cu and Zn was similar with 10% effect concentration (EC10) values ranging from 110 to 945 and from 235 to 965 mg/kg, respectively, while the corresponding median effect concentration (EC50) values ranged from 240 to 1,405 and 470 to 1,745 mg/kg, respectively. Copper toxicity values (EC10, EC20, and EC50) were best modeled by the logarithm of cation exchange capacity (CEC) and either soil pH or electrical conductivity. Zinc EC50 and EC20 values were best modeled using the logarithm of CEC, while the EC10 data were best modeled using soil pH and the logarithm of organic carbon. These models generally estimated toxicity within a factor of two of the measured values.
