THE GEOPOLITICS OF REPRODUCTIVE HEALTHCARE: LATINA IMMIGRANTS’ EXPERIENCES AS NON-CITIZENS AND BIOLOGICAL CITIZENA IN ATLANTA, GA

This dissertation examines the experiences of Latina immigrants in Atlanta, GA in accessing and receiving reproductive healthcare. Although Atlanta is a new destination city for immigrant labor, the state of Georgia has passed anti-immigrant legislation, including a 2011 law that allows local police to check immigrants’ documentation while investigating unrelated violations. This localization of immigration policing heightens immigrants’ risk of detention and deportability. In combination with media discourses of illegality, local immigration policing instills fear in immigrants, which deters them from going out in public in order to perform everyday tasks such as seeing a doctor. Latinas immigrants’ ascribed illegality is not only an issue when trying to access reproductive healthcare, however, but also inflects their interactions with health service providers. Moreover, legal and pragmatic barriers to reproductive healthcare are bound up with ideological notions of Latinas’ reproduction. Drawing from 68 interviews with recent Latina immigrants and immigrant advocates, I detail how experiences of receiving reproductive healthcare foster a “biological citizenship” – which can be defined as the ways in which an individual or group claims inclusion through biological means – that eases Latinas’ outsider status. By enacting biological citizenship through the care of their bodies, which are often viewed and treated as undeserving of care, I contend that undocumented immigrants act politically via one of the few avenues that is open to them, albeit one – the care of the body – that is often overlooked. Additionally, they are creating a bit of security in an overwhelming insecure environment. This research finds that Latina immigrants’ access to reproductive healthcare is impeded not only by anti-immigrant laws and inflammatory discourse, but also by pragmatic issues such as lack of health insurance and language differences. Moreover, legal and pragmatic barriers to reproductive healthcare are bound up with ideological notions of Latinas’ reproduction. For example, Latinas are frequently portrayed as “hyperfertile” in anti-immigrant discourse. Latina immigrants’ reproduction is viewed as threatening to the nation-state and is thus often blatantly or covertly treated to render Latinas as “undeserving” of citizenship and the welfare state. Interestingly, however, in the context of the aging population of the U.S., there are other discourses making their way onto the scene. These discourses reveal that Latina reproduction, though much maligned, was concomitantly viewed as the solution to revitalizing the eroding lower rungs of the U.S. population pyramid. Additionally, political pundits drew on the trope of the hyperfertile Latina immigrant to construct the hopes of an eventual permanent Democratic majority, which would be facilitated by the exponential breeding of Hispanic immigrants. However, this research corroborates 2015 statistics from the Centers of Disease Control that show that Hispanic fertility is steeply declining, thus undermining the demographic and political dreams which relied on tropes of the hyperfertile Latina. This study aims to expand conceptions of citizenship by examining reproductive healthcare as a site where risk is negotiated and borders of membership are both constructed and broken down. The lens of biological citizenship emphasizes the political nature of healthcare access and allows for analyzing Latina immigrants’ everyday experiences with reproductive health as they are shaped by state policies, anti-immigrant legislation, and gendered portrayals of illegality. In doing so, this study complicates healthcare access and draws out both the non-biological determinants and non-biological implications of this access

Loss of testosterone impairs anti-tumor neutrophil function.

In men, the incidence of melanoma rises rapidly after age 50, and nearly two thirds of melanoma deaths are male. The immune system is known to play a key role in controlling the growth and spread of malignancies, but whether age- and sex-dependent changes in immune cell function account for this effect remains unknown. Here, we show that in castrated male mice, neutrophil maturation and function are impaired, leading to elevated metastatic burden in two models of melanoma. Replacement of testosterone effectively normalized the tumor burden in castrated male mice. Further, the aberrant neutrophil phenotype was also observed in prostate cancer patients receiving androgen deprivation therapy, highlighting the evolutionary conservation and clinical relevance of the phenotype. Taken together, these results provide a better understanding of the role of androgen signaling in neutrophil function and the impact of this biology on immune control of malignancies

Preparation, characterisation, and topical delivery of Terbinafine

Terbinafine (TBF) is commonly used in the management of fungal infections of the skin because of its broad spectrum of activity. Currently, formulations containing the free base and salt form are available. However, there is only limited information in the literature about the physicochemical properties of this drug and its uptake by the skin. In this work, we conducted a comprehensive characterisation of TBF, and we also examined its percutaneous absorption in vitro in porcine skin. TBF-free base was synthesised from the hydrochloride salt by a simple proton displacement reaction. Both the free base and salt form were further analysed using Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). Delivery of TBF-free base in excised porcine skin was investigated from the following solvents: Isopropyl myristate (IPM), propylene glycol monolaurate (PGML), Transcutol® (TC), propylene glycol (PG), polyethylene glycol 200 (PEG 200), oleic acid (OL), ethanol (EtOH), and isopropyl alcohol (IPA). Permeation and mass balance studies confirmed that PG and TC were the most efficacious vehicles, delivering higher amounts of TBF-free base to the skin compared with a commercial gel (p < 0.05). These preliminary results are promising and will inform the development of more complex formulations in future work

Parsing Heterogeneity in the Brain Connectivity of Depressed and Healthy Adults During Positive Mood

There is well-known heterogeneity in affective mechanisms in depression that may extend to positive affect. We used data-driven parsing of neural connectivity to reveal subgroups present across depressed and healthy individuals during positive processing, informing targets for mechanistic intervention

Individual and joint trajectories of change in bone, lean mass and physical performance in older men.

BackgroundDeclines in bone, muscle and physical performance are associated with adverse health outcomes in older adults. However, few studies have described concurrent age-related patterns of change in these factors. The purpose of this study was to characterize change in four properties of muscle, physical performance, and bone in a prospective cohort study of older men.MethodsUsing repeated longitudinal data from up to four visits across 6.9 years from up to 4681 men (mean age at baseline 72.7 yrs. ±5.3) participating in the Osteoporotic Fractures in Men (MrOS) Study, we used group-based trajectory models (PROC TRAJ in SAS) to identify age-related patterns of change in four properties of muscle, physical performance, and bone: total hip bone mineral (BMD) density (g/m2) and appendicular lean mass/ht2 (kg/m2), by DXA; grip strength (kg), by hand dynamometry; and walking speed (m/s), by usual walking pace over 6 m. We also described joint trajectories in all pair-wise combinations of these measures. Mean posterior probabilities of placement in each trajectory (or joint membership in latent groups) were used to assess internal reliability of the model. The number of trajectories for each individual factor was limited to three, to ensure that the pair-wise determination of joint trajectories would yield a tractable number of groups as well as model fit considerations.ResultsThe patterns of change identified were generally similar for all measures, with three district groups declining over time at roughly similar rates; joint trajectories revealed similar patterns with no cross-over or convergence between groups. Mean posterior probabilities for all trajectories were similar and consistently above 0.8 indicating reasonable model fit to the data.ConclusionsOur description of trajectories of change with age in bone mineral density, grip strength, walking speed and appendicular lean mass found that groups identified by these methods appeared to have little crossover or convergence of change with age, even when considering joint trajectories of change in these factors

Iatrogenic cardiac perforation due to pacemaker and defibrillator leads: a contemporary multicentre experience

AIMS: To determine the incidence, clinical features, management, and outcomes of pacemaker (PM) and implantable cardioverter-defibrillator (ICD) lead cardiac perforation. Cardiac perforations due to PM and ICD leads are rare but serious complications. Clinical features vary widely and may cause diagnostic delay. Management strategies are non-guideline based due to paucity of data. METHODS AND RESULTS: A multicentre retrospective series including 3 UK cardiac tertiary centres from 2016 to 2020. Patient, device, and lead characteristics were obtained including 6-month outcomes. Seventy cases of perforation were identified from 10 631 procedures; perforation rate was 0.50% for local implants. Thirty-nine (56%) patients were female, mean ( ± standard deviation) age 74 ( ± 13.8) years. Left ventricular ejection fraction 51 ( ± 13.2) %. Median time to diagnosis was 9 (range: 0-989) days. Computed tomography (CT) diagnosed perforation with 97% sensitivity. Lead parameter abnormalities were present in 86% (whole cohort) and 98.6% for perforations diagnosed >24 h. Chest pain was the commonest symptom, present in 46%. The management strategy was percutaneous in 98.6% with complete procedural success in 98.6%. Pericardial effusion with tamponade was present in 17% and was associated with significantly increased mortality and major complications. Anticoagulation status was associated with tamponade by multivariate analysis (odds ratio 21.7, 95% confidence interval: 1.7-275.5, P = 0.018). CONCLUSIONS: Perforation was rare (0.50%) and managed successfully by a percutaneous strategy with good outcomes. Tamponade was associated with increased mortality and major complications. Anticoagulation status was an independent predictor of tamponade. Case complexity is highly variable and requires skilled operators with a multi-disciplinary approach to achieve good outcomes

3D-printed Franz cells - update on optimization of manufacture and evaluation

OBJECTIVES: Laboratory in vitro permeation processes require the use of modified Franz type diffusion cells which are conventionally fabricated from glass. Fragility and high cost are frequently associated with this type of laboratory apparatus. The purpose of our present research was to develop a simple, economical and versatile approach to manufacture Franz type cells using additive manufacturing (AM). METHODS: Graphical Franz diffusion cell designs were reproduced with a stereolithography (SLA) 3D printer and assessed over a minimum period of 24 h. The surface morphology of AM printouts was analysed before and after compatibility studies using scanning electron microscopy (SEM). Comparative permeation studies in both glass and AM Franz type diffusion cells were conducted using a caffeine solution (1.5 mg mL‑1), applied to a model silicone membrane. RESULTS: Testing of the 3D printed scaffolds confirmed similar recovery of the permeant when compared to glass cells: 1.49 ± 0.01 and 1.50 ± 0.01 mg mL‑1, respectively, after 72 h. No significant differences were visible from the SEM micrographs demonstrating consistent, smooth and non-porous surfaces of the AM Franz cells’ core structure. Permeation studies using transparent 3D printed constructs resulted in 12.85 ± 0.53 μg cm ‑2 caffeine recovery in the receptor solution after 180 min with comparable permeant recovery, 11.49 ± 1.04 μg cm ‑2, for the glass homologues. CONCLUSION: AM constructs can be considered as viable alternatives to the use of conventional glass apparatus offering a simple, reproducible and cost-effective method of replicating specialised laboratory glassware. A wider range of permeants will be investigated in future studies with these novel 3D printed Franz diffusion cells
