Attitudes Toward Transgender People Among Future Caribbean Doctors

The attitudes of medical students toward transgender people have important implications for the future quality of healthcare for Caribbean transgender patients. This paper examined the attitudes and beliefs of Caribbean medical students toward transgender people, provides psychometric evaluation of a promising instrument, and considers implications for the development of transgender curricula in Caribbean medical education. Medical students (N?=?205; 155 women, 43 men, 7 unstated) enrolled at a publicly supported Caribbean university completed the Transgender Attitudes and Beliefs Scale (TABS; Kanamori et al., 2017). Internal consistency was strong for the total TABS (α?=?.93) and more variable for the three subscales: interpersonal comfort (IC: α?=?.91), sex/gender beliefs (SGB: α?=?.89), and human value (HV: α?=?.74). Confirmatory factor analysis demonstrated acceptable overall fit for the three-factor model. There were no significant gender differences in overall attitudes toward transgender people as measured by the total TABS score; women reported higher IC scores. Scores were not correlated with age or with year in medical school. Students reported significantly more tolerant attitudes on the HV scale than on IC or SGB scales. Psychometric findings establish measurement invariance and provide support for further use of the TABS in the Caribbean. We discuss implications for medical curriculum development, including use of the TABS as a tool for medical students to reflect on their individual attitudes and beliefs regarding transgender people.

     

Fertility and digital technology: narratives of using smartphone app ‘Natural Cycles’ while trying to conceive

Fertility awareness apps, which help to identify the ‘fertile window’ when conception is most likely, have been hailed as ‘revolutionising’ women’s reproductive health. Despite rapidly growing popularity, little research has explored how people use these apps when trying to conceive and what these apps mean to them. We draw on in‐depth, qualitative interviews, adopting a critical digital health studies lens (a sub‐field of science and technology studies), to explore the experiences of cisgender women and partners with one such app, Natural Cycles, in the context of their daily lives. We found that many women valued the technology as a ‘natural’, inobtrusive alternative to biomedical intervention, and a means of controlling and knowing their bodies, amid a dearth of fertility‐related education and care. Yet this technology also intervened materially and affectively into the spaces of their lives and relationships and privileged disembodied metrics (temperature) over embodied knowledge. Meanwhile, app language, advertising and cost have contributed to characterising ‘typical’ users as white, heterosexual, affluent, cisgender women without disabilities. In the context of neoliberal shifts towards bodily self‐tracking, technologies appealing as novel, liberating and ‘natural’ to individuals who can access them may nevertheless reproduce highly gendered reproductive responsibilities, anxieties and broader health and social inequalities.     

Understanding the messages and motivation of vaccine hesitant or refusing social media influencers

BackgroundWhile anti-vaccine messages on social media have been studied for content, reach, and effectiveness, less is known about those who create and promote the messages. Online influencers, or ‘everyday people who are influential within their online social networks’, are viewed as trusted voices who are often making similar life decisions as their followers. Therefore, their experiences with and perspectives on health issues can be persuasive.MethodsWe collaborated with a formal network of online influencers to interview, using a semi-structured interview guide, vaccine hesitant influencer mothers about their views on vaccination; their process for developing health-related social media content; their motivation to promote anti-vaccine messages; and their opinions on current vaccination messaging. Prescreening ensured a diverse sample by race/ethnicity, age, education, number of children, and geographic residence. Interviews occurred by telephone, were audio recorded, and transcribed. Themes were generated independently by two coders using a deductive coding approach.ResultsWe interviewed 15 online influencer mothers from across the U.S. (average age 39 years old; all married; 13 Caucasian, 1 African American, 1 Hispanic). In some capacity, 5 of the 15 wrote about vaccination on their blog. Those who chose not to post anti-vaccine content did so for fear of alienating followers or having their platform be the site of combative discourse among readers. When researching their social media posts, the influencers did not trust mainstream sources of health information and relied on alternative sources and search engines.Implications: This exploratory study interviewed influential mothers who have the ability to spread anti-vaccine messages on social media. While most do not contribute to the anti-vaccine sentiment, understanding the motivation and practices of those that do assists the public health community in better understanding the online vaccination communication environment, leading to more effective messages to counterbalance anti-vaccine content on social media.     

Tobamovirus-plant interactions.

It is clear that the genetic information responsible for the phenomenon we think of as TMV not only consists of the genes carried in the viral genome, but that numerous plant genes are equally important in viral gene functions. These gene products not only allow the virus to replicate, but may effect functions of evolution that determine what the virus is. Even the processes of pathogenesis and resistance appear to involve similarly precise plant interactions. The challenge of the future is to identify the plant genes involved in these precise interactions and to understand both components of genetic information that comprise plant viruses.     

Effects of priming duration on retention over the first 1 1/2 years of life

Exposing individuals to an isolated component (a prime) of a prior event alleviates its forgetting. Two experiments with 120 human infants between 3 and 18 months of age determined the minimum duration of a prime that can reactivate a forgotten memory and how long the reactivated memory persists. Infants learned an operant task, forgot it, were exposed to the prime, and later were tested for renewed retention. In Experiment 1, the minimum duration of an effective prime decreased logarithmically with age, but was always longer than the duration of a mere glance. In Experiment 2, the reactivated memory was forgotten twice as fast after a minimum-duration prime as after a full-length one, irrespective of priming delay and infant age. These data reveal that the minimum effective prime duration psychophysically equates the accessibility of forgotten memories. We conclude that priming is perceptually based with effects that are organized on a ratio (log) scale.     

Phosphate transport in osteoblasts from normal and X-linked hypophosphatemic mice

Human hypophosphatemic vitamin D-resistant rickets (X-linked hypophosphatemia-XLH) is characterized by hypophosphatemia, a decreased tubular reabsorption of phosphate (P_i) and defective skeleton mineralization. Utilizing a mouse model (Hyp) of XLH, which demonstrates biological abnormalities and skeletal defects of XLH, we analyzed sodium-dependent phosphate transport in isolated osteoblasts derived from the calvaria of normophosphatemic and hypophosphatemic mice. Initial rates of phosphate uptake by normal and Hyp osteoblasts showed similar slopes. Osteoblasts from both normal and Hyp mice exhibited saturable, sodium-dependent phosphate transport with apparent V_max and K_m values not significantly different (normal mice, V_max=24.30±3.45 nmol/mg prot. 10 min, K_m=349.49±95.20 mol/liter; Hyp mice, V_max=23.03±3.41 nmol/mg prot. 10 min, K_m=453.64±106.93 mol/liter, n=24). No differences were found in the ability of normal and Hyp osteoblasts to respond to P_i transport after 5 hours of P_i deprivation. Both cell types exhibited a similar increase in cAMP in response to PTH. The accumulated results demonstrate that P_i uptake and transport in normal and Hyp mouse osteoblasts is a sodium-dependent saturable process. As osteoblast P_i uptake and transport is apparently normal in the Hyp mouse model of XLH, the osteoblastic failure described for the Hyp mouse should be attributed to other mechanism(s).
