Women and radio: sounding out new paths in women's history
Since its early introduction in the domestic sphere in the 1920s, radio has been used as a medium for the expression of women's voices, needs and concerns. In this introduction we would like to mobilise an understanding of radio as a vital source for doing women's history. Women's radio programming, women broadcasters, and women listeners provide a lens through which a number of histories can be analysed. This introduction provides an overview of the historical relationship between women and radio. It is further dedicated to research that explores the overlapping spaces of radio and women's history, and in particular, points to how radio-related source material can provide new points of departure for women's history
Lessons from Lilian Is Transnational (Media) History a Gendered Issue?
Scholarship has long demonstrated how a focus on womenâs roles can reveal
vital new elements of broadcasting history, adding critical perspectives on institutional,
aesthetic, communicatory, and participatory media narratives. This article asks: What happens if we stop looking at the stories of women in broadcasting as âmedia historyâ? What
other interpretive lenses and disciplinary traditions might we draw on, and how might we
insert media fruitfully within them? The work derives from research on the early years of
the International Association of Women in Radio and Television (IAWRT) as read from the
correspondence of founder Wilhelmina (Lilian) Posthumus-van der Goot (1897â1989), and
builds on IAWRTâs example to develop methodological considerations for writing entangled transnational histories of gender and broadcasting, absorbing insights from studies
of international organizations, collective biographies, and reconsiderations of the archive in
the digital age. KEYWORDS entanglement, International Association of Women in Radio
and Television, international organizations, media history, transnational histor
Your woman friend in the West: women broadcasters and the Cold War
© 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Radio played a paradoxical role in the Cold War, embraced both as a key tool for propaganda warfare as well as for promoting peace and understanding. Women, too, played paradoxical roles both in radio and on the world stage. In this paper we will attempt to explore these intersecting paradoxes in a transnational perspective by focusing on The International Association of Women in Radio and Television, founded in 1951. This international network of women provides insights into how women broadcasters viewed radio and themselves in the global ideological struggles of the Cold War. Exploring the organization's international networking practices, its positioning within international women's movements, as well as their conceptions of the relationship between women and radio, we show how in each of these arenas, despite a belief in a universal womanhood and striving for a global organization, the organization can be seen falling into the emerging Western camp of the Cold War
Neuroanatomical and prognostic associations of depression in Parkinson's disease.
BACKGROUND: Depression is reported as a risk factor, prodromal feature and late consequence of Parkinson's disease (PD). We aimed to evaluate the timing, neuroanatomy and prognostic implications of depression in PD. METHODS: We used data from 434 023 participants from UK Biobank with 14.1 years of follow-up. Multivariable regression models established associations of depression with incident PD and regional brain volumes. Cox proportional hazards models assessed prognostic associations of depression in PD with incident dementia and all-cause mortality. RESULTS: Of 2632 individuals with incident PD, 539 (20.5%) were diagnosed with depression at some point. Depression was associated with an increased risk of subsequent PD (risk ratio 1.53, 95% CI 1.37 to 1.72). Among incident PD cases, depression prevalence rose progressively from 10 years pre-PD diagnosis (OR 2.10, 95% CI 1.57 to 2.83) to 10 years postdiagnosis (OR 3.51, 95% CI 1.33 to 9.22). Depression severity in PD was associated with reduced grey matter volume in structures including the thalamus and amygdala. Depression prior to PD diagnosis increased risk of dementia (HR 1.47, 95% CI 1.05 to 2.07) and mortality (HR 1.30, 95% CI 1.07 to 1.58). CONCLUSIONS: This large-scale prospective study demonstrated that depression prevalence increases from 10 years before PD diagnosis and is a marker of cortical and subcortical volume loss. Depression before PD diagnosis signals a worse prognosis in terms of dementia and mortality. This has clinical implications in stratifying people with poorer cognitive and prognostic trajectory in PD
Feasibility randomized-controlled trial of online acceptance and commitment therapy for painful peripheral neuropathy in people living with HIV: The OPEN study
Background
Neuropathic pain negatively affects quality of life among people living with HIV (PLWH). This study examined the feasibility of conducting a fullâscale randomizedâcontrolled trial of online acceptance and commitment therapy (âACT OPENâ) for neuropathic pain in PLWH.
Methods
Using a parallelâgroups design, thirtyâeight participants were randomized to ACT OPEN or a waitlist control (2:1). Participants completed standard selfâreport outcome measures at baseline, and twoâ and fiveâmonths postârandomization. Participants were aware of their allocation, but assessment was blinded.
Results
Twentyâfive participants were randomized to ACT OPEN and 13 to the control (of 133 referrals). ACT OPEN completion was 69% and twoâmonth trial retention was 82%. Treatment credibility and satisfaction scores for ACT OPEN were comparable to scores reported in previous trials of cognitiveâbehavioural treatments for pain. Four adverse events were reported during the study, including one serious adverse event; all of these were unrelated to the research procedures. Small to moderate effects and 95% confidence intervals suggest that the true effect may favour ACT OPEN for improvements in pain intensity/interference and depression.
Conclusions
A fullâscale RCT of online ACT for pain management in PLWH may be feasible with refinements to trial design to facilitate recruitment.
Significance
Research on pain management in people living with HIV has primarily focused on pharmacological treatments with limited success. This is the first study to show the potential feasibility of a psychological treatment based on acceptance and commitment therapy delivered online and tailored for pain management in people with HIV (âACT OPENâ). ACT OPEN may be a promising treatment in this population and further evaluation in a fullâscale randomizedâcontrolled trial appears warranted.
Trial Registration: The trial was registered (clinicaltrials.gov; NCT03584412)
Cognitive domains affected post-COVID-19; a systematic review and meta-analysis
\ua9 2024 The Authors. European Journal of Neurology published by John Wiley & Sons Ltd on behalf of European Academy of Neurology.Background and purpose: This review aims to characterize the pattern of post-COVID-19 cognitive impairment, allowing better prediction of impact on daily function to inform clinical management and rehabilitation. Methods: A systematic review and meta-analysis of neurocognitive sequelae following COVID-19 was conducted, following PRISMA-S guidelines. Studies were included if they reported domain-specific cognitive assessment in patients with COVID-19 at >4 weeks post-infection. Studies were deemed high-quality if they had >40 participants, utilized healthy controls, had low attrition rates and mitigated for confounders. Results: Five of the seven primary Diagnostic and Statistical Manual of Mental Disorders (DSM-5) cognitive domains were assessed by enough high-quality studies to facilitate meta-analysis. Medium effect sizes indicating impairment in patients post-COVID-19 versus controls were seen across executive function (standardised mean difference (SMD) â0.45), learning and memory (SMD â0.55), complex attention (SMD â0.54) and language (SMD â0.54), with perceptual motor function appearing to be impacted to a greater degree (SMD â0.70). A narrative synthesis of the 56 low-quality studies also suggested no obvious pattern of impairment. Conclusions: This review found moderate impairments across multiple domains of cognition in patients post-COVID-19, with no specific pattern. The reported literature was significantly heterogeneous, with a wide variety of cognitive tasks, small sample sizes and disparate initial disease severities limiting interpretability. The finding of consistent impairment across a range of cognitive tasks suggests broad, as opposed to domain-specific, brain dysfunction. Future studies should utilize a harmonized test battery to facilitate inter-study comparisons, whilst also accounting for the interactions between COVID-19, neurological sequelae and mental health, the interplay between which might explain cognitive impairment
Prevalence and seasonal variation of Acanthamoeba in domestic tap water in greater Sydney, Australia
Background: This study examined the prevalence of free-living Acanthamoeba in domestic tap water in the greater Sydney region, Australia, and determined any seasonal variation in prevalence. Methods: Fifty-four participants were included in this study following approval from an institutional human research ethics committee. Each participant self-collected two samples (one in summer and another in winter) from the surface of the drain of the bathroom sink using an instructional kit. The samples were cultured by inoculating onto a non-nutrient agar plate seeded with Escherichia coli and incubation at 32°C for two weeks. The plates were microscopically examined for the presence of free-living amoeba. DNA was isolated from 20 samples and a polymerase chain reaction (PCR) assay was performed for amplification of the partial sequence of the 18S ribosomal RNA gene. The PCR amplified products were sequenced using Sanger sequencing and genotyping was performed based on the variation in nucleotide sequences. Results: A total of 97 samples were collected over the two collection periods, with 28.6 per cent of samples morphologically classified as Acanthamoeba. The summer period yielded 16 of 54 (29.6 per cent) samples classified as Acanthamoeba, while the winter period yielded 12 of 43 (27.9 per cent) samples classified as Acanthamoeba. There was no statistically significant difference (p = 0.85) between the prevalence of free-living Acanthamoeba in summer compared to winter. Phylogenetic analysis showed that 15 of 20 (75 per cent) isolates belonged to genotype T4, the most frequent genotype isolated in Acanthamoeba keratitis. Conclusion: The prevalence of free-living Acanthamoeba characterised morphologically in domestic tap water of the greater Sydney region was higher than expected, especially considering the low incidence of Acanthamoeba keratitis in Australia. However, this study did not find variation between seasons. As the T4 genotype was most common, Sydney-based practitioners must always consider Acanthamoeba as a possible causative organism in cases of microbial keratitis, regardless of the season
Consumer e-health education in HIV/AIDS: a pilot study of a web-based video workshop
BACKGROUND: Members of the HIV/AIDS community are known to use web-based tools to support learning about treatment issues. Initial research indicated components such as message forums or web-based documentation were effectively used by persons with HIV/AIDS. Video has also shown promise as a technology to aid consumer health education. However, no research has been published thus far investigating the impact of web-based environments combining these components in an educational workshop format. METHODS: In this qualitative study HIV/AIDS community members provided feedback on an integrated web-based consumer health education environment. Participants were recruited through organizations that serve the HIV/AIDS community located in Toronto, Canada. Demographics, data on Internet use, including messages exchanged in the study environment were collected. A group interview provided feedback on usability of the study environment, preferences for information formats, use of the message forum, and other sources for learning about treatment information. RESULTS: In this pilot study analysis of the posted messages did not demonstrate use for learning of the workshop content. Participants did not generally find the environment of value for learning about treatment information. However, participants did share how they were meeting these needs. It was indicated that a combination of resources are being used to find and discuss treatment information, including in-person sources. CONCLUSION: More research on the ways in which treatment information needs are being met by HIV/AIDS community members and how technology fits in this process is necessary before investing large amounts of money into web-based interventions. Although this study had a limited number of participants, the findings were unexpected and, therefore, of interest to those who intend to implement online consumer health education initiatives or interventions
Nontransgenic models of breast cancer
Numerous models have been developed to address key elements in the biology of breast cancer development and progression. No model is ideal, but the most useful are those that reflect the natural history and histopathology of human disease, and allow for basic investigations into underlying cellular and molecular mechanisms. We describe two types of models: those that are directed toward early events in breast cancer development (hyperplastic alveolar nodules [HAN] murine model, MCF10AT human xenograft model); and those that seek to reflect the spectrum of metastatic disease (murine sister cell lines 67, 168, 4T07, 4T1). Collectively, these models provide cell lines that represent all of the sequential stages of progression in breast disease, which can be modified to test the effect of genetic changes
