Reproductive justice: Non-interference or non-domination?

The reproductive justice movement started by black women's rights activists made its way into the academic literature as an intersectional approach to women's reproductive autonomy. While there are many scholars who now employ the term 'reproductive justice' in their research, few have taken up the task of explaining what 'justice' entails in reproductive justice. In this paper I take up part of this work and attempt to clarify the relevant kind of freedom an adequate theory of reproductive justice would postulate. To do so, I compare two approaches to reproductive freedom: an approach based on freedom as non-interference and an approach based on freedom as non-domination. I then argue that the non-domination approach better fits the ideals of the reproductive justice movement as set forth by its founders and should be treated as one of the necessary conditions in any non-ideal account of reproductive justice. Towards the end, I single out epistemic non-domination as crucial in shaping the narrative around reproductive justice.

Autonomy, Competence and Non-interference.

In light of the variety of uses of the term autonomy in recent bioethics literature, in this paper, I suggest that competence, not being as contested, is better placed to play the anti-paternalistic role currently assigned to autonomy. The demonstration of competence, I will argue, can provide individuals with robust spheres of non-interference in which they can pursue their lives in accordance with their own values. This protection from paternalism is achieved by granting individuals rights to non-interference upon demonstration of competence. In this paper, I present a risk-sensitive account of competence as a means of grounding rights to non-interference. On a risk-sensitive account of competence individuals demonstrate their competence by exercising three capacities to the extent necessary to meet a threshold determined by the riskiness of the decision. These three capacities are the capacity to (i) acquire knowledge, (ii) use instrumental rationality, and (iii) form and revise a life plan.

Noninterference of Rotavirus Vaccine With Measles-Rubella Vaccine at 9 Months of Age and Improvements in Antirotavirus Immunity: A Randomized Trial.

BACKGROUND: The burden of rotavirus morbidity and mortality is high in children aged <5 years in developing countries, and evaluations indicate waning protection from rotavirus immunization in the second year. An additional dose of rotavirus vaccine may enhance the immune response and lengthen the period of protection against disease, but coadministration of this dose should not interfere with immune responses to concurrently given vaccines. METHODS: A total of 480 9-month-old participants from Matlab, Bangladesh, were enrolled in a study with a primary objective to establish noninferiority of concomitant administration of measles-rubella vaccine (MR) and a third dose of human rotavirus vaccine (HRV; MR + HRV), compared with MR given alone. Secondary objectives included noninferiority of rubella antibody seroconversion and evaluating rotavirus IgA/IgG seroresponses in MR + HRV recipients. RESULTS: Two months after vaccination, 75.3% and 74.3% of MR + HRV and MR recipients, respectively, had seroprotective levels of measles virus antibodies; 100.0% and 99.6%, respectively, showed anti-rubella virus immunoglobulin G (IgG) seroprotection. In the MR + HRV group, antirotavirus immunoglobulin A and IgG seropositivity frequencies before vaccination (52.7% and 66.3%, respectively) increased to 69.6% and 88.3% after vaccination. CONCLUSIONS: Vaccine-induced measles and rubella antibody responses are not negatively affected by concomitant administration of HRV. The HRV dose increases antirotavirus serum antibody titers and the proportion of infants with detectable antirotavirus antibody. CLINICAL TRIALS REGISTRATION: NCT01700621.

Immune non-interference and safety study of Vi-DT typhoid conjugate vaccine with a measles, mumps and rubella containing vaccine in 9-15 months old Nepalese infants.

BACKGROUND: Typhoid fever is a common disease in developing countries especially in the Indian subcontinent and Africa. The available typhoid conjugate vaccines (TCV) have been found to be highly immunogenic in infants and children less than 2 years of age. Many countries are planning to adopt TCV in their routine EPI programs around 9 months of age when measles containing vaccines are given. Therefore, Vi-DT TCV was tested in 9-15 months aged healthy infants in Nepal to demonstrate non-interference with a measles containing vaccine. METHODS: This was a randomized, open label, phase III study to assess the immune non-interference, safety, and reactogenicity of Vi-DT typhoid conjugate vaccine when given concomitantly with measles, mumps and rubella (MMR) vaccine. A total of 360 participants aged 9-15 months were enrolled and randomized equally into Vi-DT + MMR (180 participants) or MMR alone (180 participants) group and were evaluated for immunogenicity and safety 28 days post vaccination. RESULTS: Using the immunogenicity set, difference between proportions (95% CI) of the Vi-DT + MMR group vs MMR alone group were -2.73% (-8.85, 3.38), -3.19% (-11.25, 4.88) and 2.91% (-3.36, 9.18) for sero-positivity rate of anti-measles, anti-mumps and anti- rubella, respectively. Only the lower bound of the range in difference of the proportions for sero-positivity rate of anti-mumps did not satisfy the non-inferiority criteria as it was above the -10% limit, which may not be of clinical significance. These results were confirmed in the per protocol set. There were no safety concerns reported from the study and both Vi-DT + MMR and MMR alone groups were comparable in terms of solicited and unsolicited adverse events . CONCLUSIONS: Results indicated that there is non-interference of MMR vaccine with Vi-DT and Vi-DT conjugate vaccine could be considered as an addition to the EPI schedule among children at risk of contracting typhoid.

Reversal of Bortezomib-Induced Neurotoxicity by Suvecaltamide, a Selective T-Type Ca-Channel Modulator, in Preclinical Models.

This study evaluated suvecaltamide, a selective T-type calcium channel modulator, on chemotherapy-induced peripheral neurotoxicity (CIPN) and anti-cancer activity associated with bortezomib (BTZ). Rats received BTZ (0.2 mg/kg thrice weekly) for 4 weeks, then BTZ alone (n = 8) or BTZ+suvecaltamide (3, 10, or 30 mg/kg once daily; each n = 12) for 4 weeks. Nerve conduction velocity (NCV), mechanical threshold, ß-tubulin polymerization, and intraepidermal nerve fiber (IENF) density were assessed. Proteasome inhibition was evaluated in peripheral blood mononuclear cells. Cytotoxicity was assessed in human multiple myeloma cell lines (MCLs) exposed to BTZ alone (IC50 concentration), BTZ+suvecaltamide (10, 30, 100, 300, or 1000 nM), suvecaltamide alone, or vehicle. Tumor volume was estimated in athymic nude mice bearing MCL xenografts receiving vehicle, BTZ alone (1 mg/kg twice weekly), or BTZ+suvecaltamide (30 mg/kg once daily) for 28 days, or no treatment (each n = 8). After 4 weeks, suvecaltamide 10 or 30 mg/kg reversed BTZ-induced reduction in NCV, and suvecaltamide 30 mg/kg reversed BTZ-induced reduction in IENF density. Proteasome inhibition and cytotoxicity were similar between BTZ alone and BTZ+suvecaltamide. BTZ alone and BTZ+suvecaltamide reduced tumor volume versus the control (day 18), and BTZ+suvecaltamide reduced tumor volume versus BTZ alone (day 28). Suvecaltamide reversed CIPN without affecting BTZ anti-cancer activity in preclinical models.

Surface and Interface Engineering of Nanoarrays toward Advanced Electrodes and Electrochemical Energy Storage Devices.

The overall performance of electrochemical energy storage devices (EESDs) is intrinsically correlated with surfaces and interfaces. As a promising electrode architecture, 3D nanoarrays (3D-NAs) possess relatively ordered, continuous, and fully exposed active surfaces of individual nanostructures, facilitating mass and electron transport within the electrode and charge transfer across interfaces and providing an ideal platform for engineering. Herein, a critical overview of the surface and interface engineering of 3D-NAs, from electrode and interface designs to device integration, is presented. The general merits of 3D-NAs and surface/interface engineering principles of 3D-NA hybrid electrodes are highlighted. The focus is on the use of 3D-NAs as a superior platform to regulate the interface nature and unveiling new mechanism/materials without the interference of binders. The engineering and utilization of the surface of 3D-NAs to develop flexible/solid-state EESDs with 3D integrated electrode/electrolyte interfaces, or 3D triphase interfaces involving other active species, which are characteristic of (quasi-)solid-state electrolyte infiltration into the entire device, are also considered. Finally, the challenges and future directions of surface/interface engineering of 3D-NAs are outlined. In particular, potential strategies to obtain electrode charge balance, optimize the multiphase solid-state interface, and attain 3D solid electrolyte infiltration are proposed.

Efficacy of a new topical formulation containing selamectin plus sarolaner against three common tick species infesting cats in the United States.

The efficacy of a single topical application of a combination product containing selamectin and sarolaner (selamectin/sarolaner; Revolution® Plus/Stronghold® Plus) was evaluated in seven laboratory studies against Ixodes scapularis (three studies), Dermacentor variabilis (two studies), or Amblyomma maculatum (two studies). In each study, cats were randomly allocated to treatment groups based on pre-treatment host-suitability tick counts. On Days -2, 5, 12, 19, 26 and 33, the cats were infested with unfed adult ticks. On Day 0, cats were treated with either a placebo (vehicle control) or with the spot-on solution at the minimum dose of 6.0 mg selamectin and 1.0 mg sarolaner/kg bodyweight. In one study with I. scapularis and one with D. variabilis an additional group of cats was treated with selamectin alone (Revolution®, Zoetis) at 6.0 mg/kg bodyweight. Tick counts were conducted after treatment and after each weekly re-infestation and efficacy determined relative to placebo-treated animals. There were no treatment-related adverse reactions in any of the studies. Geometric mean live tick counts were significantly (P < 0.05) lower in the selamectin/sarolaner-treated groups compared to the geometric mean tick counts in the placebo-treated groups at all time-points in all studies. For all species, a single topical administration of the selamectin/sarolaner combination resulted in>90% efficacy against existing infestations based on geometric means. Efficacy against weekly re-infestations was >90% based on geometric means for at least 5 weeks for I. scapularis and D. variabilis, and for at least 4 weeks against A. maculatum. Selamectin alone had no efficacy against I. scapularis, where counts on selamectin-treated cats were not significantly different from placebo at all time points (P > 0.05), and for D. variabilis, counts were not significantly different from placebo at 2, 3 and 5 weeks after treatment (P > 0.05) and efficacy was never greater than 85%. Thus, the activity of the sarolaner against three common tick species found on cats in the US is complementary to the existing broad-spectrum parasite control of selamectin. The inclusion of sarolaner with selamectin in a combination product (Revolution® Plus/Stronghold® Plus) provides for the treatment of existing tick infestations and gives at least one month of control against re-infestation following a single topical application.
