Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research.

Successful treatment of Rhizopus arrhizus rhino-orbital-cerebral mucormycosis with isavuconazole salvage therapy following extensive debridement

A 61-year old lady with poorly-controlled type 2 diabetes mellitus was diagnosed with rhino-orbital-cerebral mucormycosis following presentation with sinusitis, ophthalmoplegia, proptosis and facial numbness. She was treated successfully with aggressive surgical intervention including orbital exenteration, accompanied by anti-fungal therapy with liposomal amphotericin B and posaconazole, followed by isavuconazole as salvage therapy. We discuss the challenges around optimising antifungal therapy of this lethal infection in the context of hepatic and renal toxicity.

WASP (write a scientific paper): The ongoing process of ethical decision-making in qualitative research: Ethical principles and their application to the research process

The nature of qualitative research is fundamentally different from quantitative research. In depth understanding and exploration of specific phenomena or their significance usually involve a data collection process with a select few participants with whom the researcher interacts over an extended period of time. The participants are not anonymous to the researcher and they also reveal personal information. Research participants' rights need to be protected, even more so in this type of qualitative work. This chapter discusses how ethical decision-making needs to be ongoing during the research process by applying the principles of respect for persons, beneficence and justice. Respecting research participants, involves addressing issues related to informed consent, anonymity and confidentiality while also reflecting on the researcher's impact on the participant and the research context while the research is carried out and also when the research is disseminated. The second principle of beneficence calls for the researcher to ascertain that participants' safety is given utmost importance. Finally, justice refers to ensuring that the burdens and benefits of research are shared fairly without any form of discrimination or manipulation. These principles offer the researcher flexible tools to reflect on ethical decisions as they arise throughout the research process.

Dielectric properties of muscle and adipose tissue-mimicking solutions for microwave medical imaging applications

The aim of the present study was to synthesize mixture solutions which can accurately mimic the dielectric properties of biological tissues, specifically muscle and adipose tissues between 500 MHz and 50 GHz. Mixtures utilizing concentrations of bovine serum albumin (BSA) dissolved in phosphate buffered saline (PBS) and Ringer's solutions were synthesized to mimic in vivo and ex vivo muscle tissues. Solutions consisting of concentrations of peanut oil and Triton X-100 (TX) in PBS and Ringer's solutions were also synthesized to mimic in vivo and ex vivo adipose tissue. Results were then analysed and compared to measured dielectric properties of in vivo and ex vivo biological tissues from another previous study. Good agreement with said dielectric property measurements were obtained since the solutions from this study yielded low RMSE and RMSRE values. This implied that such solutions can be utilized in the construction of human body phantoms for narrowband and ultra-wideband microwave devices for near field breast cancer imaging.

Have You Asked for It? An Exploratory Study About Maltese Adolescents’ Use of Ask.fm

This article focuses on adolescents’ use of anonymous social networking sites (SNSs). Their perceptions and attitudes toward one such platform, Ask.fm, are discussed using the framework of uses and gratifications theory to explore motivations for using it. Four focus groups and four interviews were carried out with 22 Maltese adolescents (10 female and 12 male) aged 11 to 16 years. Thematic analysis of data collected was undertaken to identify and develop themes relevant to Ask.fm use. Findings indicate that the platform is a space where adolescents interact with others as part of their identity exploration. The role of anonymity was salient throughout. Ask.fm users were aware of the risks related to using the site; yet, the possibilities for fun, peer acceptance, and identity exploration may be driving them to experiment with this risky behavior. The implications arising from these exploratory findings may be applicable to other anonymous SNSs.

Accurate in vivo dielectric properties of liver from 500 MHz to 40 GHz and their correlation to ex vivo measurements

In this article, we report on the characterization of the dielectric properties of in vivo rat liver at 36.4°C from 500 MHz up to 40 GHz with less than 5% uncertainty. The measured data were fitted to a Cole-Cole model and dielectric parameters are presented together with their respective 95% confidence interval. The root mean square error is 0.42. Moreover, ex vivo measurements were conducted in situ at 1, 2, 4 and 6 min after animal death and are compared to in vivo measurements. The results show that immediate changes in [Formula: see text]and [Formula: see text] are within experimental uncertainty, and therefore changes between in vivo and published ex vivo dielectric properties can be attributed to tissue hydration.
