Bhabha in the clinic

Before professional diagnosis, the determination of whether one is ‘ill’ or ‘well’ rests within the patient. These moments, when sufferers (re)cognize their own bodily and phenomenological experience as abnormal or different, are critical to the positioning of healer and patient. So too are moments when diagnosed patients, struggling with a treatment regime, compromise and adjust to embrace, if only partially, disparate ideas of health. In this article, I apply Homi Bhabha’s framework of hybridity and difference to think about the perception of illness, self-diagnosis, and power in healing relationships. I consider how sufferers enact hybrid positions between their bodily perceptions and their professional diagnoses. To illustrate the utility of Bhabha’s colonial critique for health care, I examine narratives by patients with diabetes-related vision loss about: (1) first realizations that something was wrong, what Bhabha might call the ‘intervention of difference’; (2) expressed differences between self-knowledge and biomedical knowledge, corresponding to Bhabha’s ‘partial embrace’ of the colonial ideal; and (3) the self-colonizing epistemological work that compliant patients do as they re-orient their pre-diagnostic self to a post-diagnostic habitus of self-monitoring, timed medications, and other treatments. I conclude with a discussion of how Bhabha’s colonial hybridity supports a more productively contentious medical anthropology that envisions and pursues decolonized health care

Epidemiological placism in public health emergencies: Ebola in two Dallas neighborhoods

Super-diverse cities face distinctive challenges during infectious disease outbreaks. For refugee and immigrant groups from epidemic source locations, identities of place blend with epidemiological logics in convoluted ways during these crises. This research investigated the relationships of place and stigma during the Dallas Ebola crisis. Ethnographic results illustrate how Africanness, more than neighborhood stigma, informed Dallas residents’ experience of stigma. The problems of place-based stigma, the imprecision of epidemiological placism, and the cohesion of stigma to semiotically powerful levels of place – rather than to realistic risk categories – are discussed. Taking its authority from epidemiology, placism is an important source of potential stigma with critical implications for the success of public health messaging

Family and Family-Like Relations for Transnational Migrants: Ideals of Care Informed by Kin, Non-Family, and Religion

Studies of transnational family formation and care relationships suggest that, while family forms and care values are idealized, they are also negotiated, enacted, and fluid constructs. Strategies of resilience and mechanisms of flexible care achieved by transnational families are fine-tuned under multiple influences. Among these influences are well-known sources such as social networks, as well as less well-understood sources such as religious teachings. We report findings of a 4-month, ethnographic study among Latinx immigrants to the U.S. whose (n = 14) narratives of family “care” reflect their ideals and simultaneously work to linguistically produce role continuity. Thematic results address three key strategies for achieving this continuity: (1) valuations of flexibility; (2) family-like care by non-family and church members; and (3) commitments to and reliance on new networks, particularly through church relations. We conclude by suggesting how family-like care, such as that from church relations, informs the flexible relational obligations, resources, resiliencies, and values of transnational migrants

The traditional food of migrants: Meat, water, and other challenges for dietary advice. An ethnography in Guanajuato, Mexico

The term “traditional diet” is used variously in public health and nutrition literature to refer to a substantial variety of foodways. Yet it is difficult to draw generalities about dietary tradition for specific ethnic groups. Given the strong association between migration and dietary change, it is particularly important that dietary advice for migrants be both accurate and specific. In this article, I examine the cultural construct of “traditional foods” through mixed method research on diet and foodways among rural farmers in Guanajuato, MX and migrants from this community to other Mexican and U.S. destinations. Findings reveal first, that quantitatively salient terms may contain important variation, and second, that some “traditional” dietary items –like “refresco,” “carne,” and “agua” – may be used in nutritionally contradictory ways between clinicians and Mexican immigrant patients. Specifically, the term “traditional food” in nutritional advice for Mexican migrants may be intended to promote consumption of fresh produce or less meat; but it may also invoke other foods (e.g., meats or corn), inspire more regular consumption of formerly rare foods (e.g., meats, flavored waters), or set up financially impossible goals (e.g., leaner meats than can be afforded). Salience studies with ethnographic follow up in target populations can promote the most useful and accurate terms for dietary advice

The mTOR regulated RNA-binding protein LARP1 requires PABPC1 for guided mRNA interaction.

The mammalian target of rapamycin (mTOR) is a critical regulator of cell growth, integrating multiple signalling cues and pathways. Key among the downstream activities of mTOR is the control of the protein synthesis machinery. This is achieved, in part, via the co-ordinated regulation of mRNAs that contain a terminal oligopyrimidine tract (TOP) at their 5'ends, although the mechanisms by which this occurs downstream of mTOR signalling are still unclear. We used RNA-binding protein (RBP) capture to identify changes in the protein-RNA interaction landscape following mTOR inhibition. Upon mTOR inhibition, the binding of LARP1 to a number of mRNAs, including TOP-containing mRNAs, increased. Importantly, non-TOP-containing mRNAs bound by LARP1 are in a translationally-repressed state, even under control conditions. The mRNA interactome of the LARP1-associated protein PABPC1 was found to have a high degree of overlap with that of LARP1 and our data show that PABPC1 is required for the association of LARP1 with its specific mRNA targets. Finally, we demonstrate that mRNAs, including those encoding proteins critical for cell growth and survival, are translationally repressed when bound by both LARP1 and PABPC1

BurstCube: A CubeSat for gravitational wave counterparts

BurstCube aims to expand sky coverage in order to detect, localize, and rapidly disseminate information about gamma-ray bursts (GRBs). BurstCube is a\u276U\u27 CubeSat with an instrument comprised of 4 Cesium Iodide (CsI) scintillators coupled to arrays of Silicon photo-multipliers (SiPMs) and will be sensitive to gamma-rays between 50 keV and 1 MeV. BurstCube will assist current observatories, such as Swift and Fermi, in the detection of GRBs as well as provide astronomical context to gravitational wave (GW) events detected by LIGO, Virgo, and KAGRA. BurstCube is currently in its development phase with a launch readiness date in early 2022

Repeat Placental Growth Factor-Based Testing in Women With Suspected Preterm Preeclampsia: A Stratified Analysis of the PARROT-2 Trial

BACKGROUND: PlGF (placental growth factor)-based testing reduces severe maternal adverse outcomes. Repeat PlGF-based testing is not associated with improved perinatal or maternal outcomes. This planned secondary analysis aimed to determine whether there is a subgroup of women who benefit from repeat testing. METHODS: Pregnant individuals with suspected preterm preeclampsia were randomized to repeat revealed PlGF-based testing, compared with usual care where testing was concealed. Perinatal and maternal outcomes were stratified by trial group, by initial PlGF-based test result, and by PlGF-based test type (PlGF or sFlt-1 [soluble fms-like tyrosine kinase-1]/PlGF ratio). RESULTS: A total of 1252 pregnant individuals were included. Abnormal initial PlGF-based test identified a more severe phenotype of preeclampsia, at increased risk of adverse maternal and perinatal outcomes. Repeat testing was not significantly associated with clinical benefit in women with abnormal initial results. Of women with a normal initial result, 20% developed preeclampsia, with the majority at least 3 to 4 weeks after initial presentation. Repeat test results were more likely to change from normal to abnormal in symptomatic women (112/415; 27%) compared with asymptomatic women (163/890; 18%). A higher proportion of symptomatic women who changed from normal to abnormal were diagnosed with preeclampsia, compared with asymptomatic women. CONCLUSIONS: Our results do not demonstrate evidence of the clinical benefit of repeating PlGF-based testing if the initial result is abnormal. Judicious use of repeat PlGF-based testing to stratify risk may be considered at least 2 weeks after a normal initial test result, particularly in women who have symptoms or signs of preeclampsia.

Pan-Cancer Analysis of lncRNA Regulation Supports Their Targeting of Cancer Genes in Each Tumor Context

Long noncoding RNAs (lncRNAs) are commonly dys-regulated in tumors, but only a handful are known toplay pathophysiological roles in cancer. We inferredlncRNAs that dysregulate cancer pathways, onco-genes, and tumor suppressors (cancer genes) bymodeling their effects on the activity of transcriptionfactors, RNA-binding proteins, and microRNAs in5,185 TCGA tumors and 1,019 ENCODE assays.Our predictions included hundreds of candidateonco- and tumor-suppressor lncRNAs (cancerlncRNAs) whose somatic alterations account for thedysregulation of dozens of cancer genes and path-ways in each of 14 tumor contexts. To demonstrateproof of concept, we showed that perturbations tar-geting OIP5-AS1 (an inferred tumor suppressor) andTUG1 and WT1-AS (inferred onco-lncRNAs) dysre-gulated cancer genes and altered proliferation ofbreast and gynecologic cancer cells. Our analysis in-dicates that, although most lncRNAs are dysregu-lated in a tumor-specific manner, some, includingOIP5-AS1, TUG1, NEAT1, MEG3, and TSIX, synergis-tically dysregulate cancer pathways in multiple tumorcontexts
