description: The irreversibility of the martensite transition in magnetic shape memory alloys (MSMAs) with respect to external magnetic field is one of the biggest challenges that limits their application as giant caloric materials. This transition is a magneto-structural transition that is accompanied with a steep drop in magnetization (i.e., 'delta M') around the martensite start temperature (Ms) due to the lower magnetization of the martensite phase. In this communication, we show that 'delta M' around Ms in Mn rich Ni-Mn based MSMAs gets suppressed by two orders of magnitude in crushed powders due to the stabilization of the martensite phase at temperatures well above the Ms and the austenite finish (Af) temperatures due to residual stresses. Analysis of the intensities and the FWHM of the x-ray powder diffraction patterns reveals stabilized martensite phase fractions as 97, 75 and 90% with corresponding residual microstrains as 5.4, 5.6 and 3% in crushed powders of the three different Mn rich Ni-Mn alloys, namely, Mn1.8Ni1.8In0.4, Mn1.75Ni1.25Ga and Mn1.9Ni1.1Ga, respectively. Even after annealing at 773 K, the residual stress stabilised martensite phase does not fully revert to the equilibrium cubic austenite phase as the magneto-structural transition is only partially restored with reduced value of 'delta M'. Our results have very significant bearing on application of such alloys as inverse magnetocaloric and barocaloric materials.
title: Exploring Extended Radio Galaxies with LOFAR
Creators: name: Barkus, Bonny
Publisher: name: The Open University

description: Extended radio sources are an important minority population in modern, deep radio surveys because they enable detailed investigation of the physics governing radio-emitting regions such as active galaxies and their environments. The Low-frequency array (LOFAR) Two-metre Sky Survey (LoTSS), at 150 MHz, is the largest radio survey to date in terms of numbers of sources and data volume, and is sensitive to both compact and extended emission, making it ideal for the study of extended radio sources. Cross-identification of radio sources with optical host galaxies is challenging for this extended population, due to their morphological complexity. In LoTSS Data Release 1 an automated statistical identification process for compact sources was supplemented by a citizen science identification process. I present a novel method for automating the host identification of extended sources by using ridgelines, which trace the assumed direction of fluid flow through the points of highest flux density. Applying my code, RL-XID, I demonstrate that ridgelines are versatile; they can be used both for optical host identification and morphological studies. RL-XID draws ridgelines for 85% of sources brighter than 10 mJy and larger than 15 arcsec, with an improved performance of 96% for the subset >30 mJy and >60 arcsec. I demonstrate that RL-XID successfully identifies the host for 98% of the sources with successfully drawn ridgelines, and performs at a comparable level to visual identification via citizen science. Exploring galaxy populations helps us to understand their evolution and build better population models. I present new VLA observations that reveal the structure of a population of low-luminosity FRII radio galaxies discovered in LoTSS. Fanaroff and Riley (1974) identified a relationship between luminosity and radio structure, with FRIs having low-luminosity, centre bright jets and FRIIs having higher luminosity, edge-brightened jets. Using LoTSS, Mingo et al (2019) demonstrated an overlap in luminosity between FRI/FRII morphology, discovering a sub-sample of FRIIs with luminosities up to three magnitudes lower than the typical FR break. To continue to apply the traditional FR classifications in upcoming surveys we need to understand the structure and dynamics of the low-luminosity FRII population. The VLA observations I present in this thesis are a sample of LoTSS-selected low-luminosity FRIIs which allow me to make comparisons between the two FRII luminosity populations. I found systematic differences in the prevalence of compact features, with a higher fraction of cores in the low luminosity sample, and a higher fraction of hotspots in the high luminosity sources. I have also identified six new remnant candidates and three new restarting candidate sources.

description: Background: Anorexia nervosa (AN) is a serious mental disorder associated with high levels of psychological comorbidity, physical complications, and mortality. Treatment outcomes for AN with best available psychological therapies remain poor. Examination of AN comorbidities and prognostic variables have been highlighted as research areas with high potential. Methods: We examined data from the MOSAIC trial, a multi-site RCT for AN including 142 individuals. We conducted network analyses for (1) AN symptomatology and (2) AN comorbidity with depression and anxiety at all available time points. We conducted linear regressions to determine whether centrality of symptoms in the baseline network was predictive of patient recovery status and clinical impairment at 12-months follow-up. Results: Feeling fat, fear of weight gain, discomfort seeing one's own body, dissatisfaction with weight, and desire to lose weight were among the most central symptoms of AN. Feelings of worthlessness had the highest bridge centrality connecting depression to AN. Centrality of symptoms in the network at baseline was highly related to prognostic value in predicting post-treatment recovery status (r2 = 0.52, p < 0.001) and clinical impairment (r2 = 0.55, p < 0.001). Conclusions: We identified central symptoms of AN and bridge symptoms between AN, depression, and anxiety. These analyses generate useful hypotheses about the etiology and maintenance of AN and related comorbidities, and also generate hypotheses concerning ideal treatment. The validity of network theory in identifying important symptoms is supported by the finding that symptom centrality was closely related to prognostic utility.
Itô's formula for finite variation Lévy processes: The case of non-smooth functions

description: Extending Itô's formula to non-smooth functions is important both in theory and applications. One of the fairly general extensions of the formula, known as Meyer-Itô, applies to one dimensional semimartingales and convex functions. There are also satisfactory generalizations of Itô's formula for diffusion processes where the Meyer-Itô assumptions are weakened even further. We study a version of Itô's formula for multi-dimensional finite variation Lévy processes assuming that the underlying function is continuous and admits weak derivatives. We also discuss some applications of this extension, particularly in finance.

description: Pain management has taken a prominent place in public health agendas, with considerable attention focused on the general population. Non-cancer pain is a common health condition in the disability population, although this is not acknowledged in existing guidelines or public health strategies, and generalizable information on the subject is limited. Thus, a comprehensive review of available information which is related to both pain and disability is of interest to the researchers.

description: This course examines the many ways in which modern warfare affects the health of men, women, and children worldwide. Rather than a chronological analysis of war in the twentieth century, we will focus on the human experience of warfare and the interplay between collective violence and the health of a population. The objectives of this course are: (1) to understand the relationship between war and human health; (2) to gain a basic understanding of the core theories of civil and inter-state conflict; (3) to determine the main processes by which conflict affects individual health and public health systems (4) to identify the most effective health-focused intervention strategies in the context of conflict or post-conflict areas.

description: We study the excitation of axial quasi-normal modes of deformed non-rotating black holes by test-particles and we compare the associated gravitational wave signal with that expected in general relativity from a Schwarzschild black hole. Deviations from standard predictions are quantified by an effective deformation parameter, which takes into account deviations from both the Schwarzschild metric and the Einstein equations. We show that, at least in the case of non-rotating black holes, it is possible to test the metric around the compact object, in the sense that the measurement of the gravitational wave spectrum can constrain possible deviations from the Schwarzschild solution.

The Safe Minimum Standard of Conservation and Environmental Economics

description: Critics within environmental economics argue that the mainstream paradigm is not sufficiently cautious to support sound decision making about the long-run future of environmental resources. Rather than basing choices on benefits and costs, these upstarts, beginning with Ciriacy-Wantrup* (1968), argue that decision-makers should consider imposing a safe minimum standard of conservation (hereafter the SMS). The SMS has intuitive appeal. Where loss or degradation of environmental resources could have large adverse economic consequences, safety-first makes common sense. The SMS continues to be discussed in the professional literature3 and has found its way into some textbook^.^ However, the SMS has not achieved wide acceptance among environmental economists.

Integration of Continuous Labor Support Within American Obstetric Care:  A Review of Advancements and Persisting Barriers
Creators: name: Sanchez, Alexandria
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The purpose of this paper was to review current models for integrating continuous labor support into the standard practice of American obstetric care to identify successes and persisting barriers that delay large-scale implementation. Following a detailed literature review on the impact of doula services, an analysis of current programs and policies outline the advancements in the field taking place at the national level. Such programs offer valuable representations of successful development, implementation, and scale-up of doula care for marginalized populations. Lastly, recommendations are made that identify areas for advancement within the field, while present barriers are discussed to target obstacles documented within doula care that have impeded upon large-scale implementation of service delivery. The impact of doula care as an evidence-based obstetric intervention has proven a highly effective tool for improving birth outcomes and overall measures of support for low-income women of color within the United States. While there remains a void in policy development, specific legislation enacted within individual states support doula services under the Medicaid care model for pregnancy services. Although such policy shifts advance the practice of doula services, there remain issues with reimbursement that must be addressed to sustain the practice of doula care for all women. Lastly, the work of doulas must be recognized by the broader MCH community of leaders as an evidence-based intervention that, with further research and improved monitoring and evaluation tools can present as an effective method for improving health outcomes within a variety of obstetric care settings.

description: Among the so-called classical tests of general relativity (GR), light bending has been confirmed with an accuracy that increases as times goes by. Here we study the gravitational deflection of photons within the framework of classical and semiclassical higher-derivative gravity (HDG) -- the only version of GR that is known up to now to be renormalizable along with its matter couplings. Since our computations are restricted to scales much below the Planck cut-off we need not be afraid of the massive spin-2 ghost that haunts HDG. An upper bound on the constant related to the $R^2_{μν}$-sector of the theory is then found by analyzing -- from a classical and semiclassical viewpoint -- the deflection angle of a photon passing by the Sun. This upper limit greatly improves that available in the literature.

description: The Pauli exclusion principle as constraint on fermionic occupation numbers is a consequence of the much deeper fermionic exchange statistics. Just recently, it was shown by Klyachko that this antisymmetry of fermionic wave functions leads to further restrictions on natural occupation numbers. These so-called generalized Pauli constraints (GPC) significantly strengthen Pauli's exclusion principle. Our first goal is to develop an understanding of the mathematical concepts behind Klyachko's work, in the context of quantum marginal problems. Afterwards, we explore the physical relevance of GPC and study concrete physical systems from that new viewpoint. In the first part of this thesis we review Klyachko's solution of the univariate quantum marginal problem. In particular we break his abstract derivation based on algebraic topology down to a more elementary level and reveal the geometrical picture behind it. The second part explores the possible physical relevance of GPC. We review the effect of pinning, i.e. the saturation of some GPC by given natural occupation numbers and explain its consequences. Although this effect would be quite spectacular we argue that pinning is unnatural. Instead, we conjecture the effect of quasipinning, defined by occupation numbers close to (but not exactly on) the boundary of the allowed region. In the third part we study concrete fermionic quantum systems from the new viewpoint of GPC. In particular, we compute the natural occupation numbers for the ground state of a family of interacting fermions in a harmonic potential. Intriguingly, we find that the occupation numbers are strongly quasipinned, even up to medium interaction strengths. We identify this as an effect of the lowest few energy eigenstates, which provides first insights into the mechanism behind quasipinning.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Objective: To determine if the implementation of the Pregnancy Medical Home program in North Carolina corresponded with changes in the primary cesarean rate among Medicaid beneficiaries. Methods: NC Birth Certificate Data from 2011 and 2013 were analyzed using logistic regression to compare differences in Medicaid and non-Medicaid populations. The outcome variable was primary cesarean delivery and the exposure of interest was payment status. Results: The results suggest that there was a statistically significant decrease in primary cesarean deliveries unique to Medicaid beneficiaries from 2011 to 2013. Conclusion: A decrease in primary cesarean deliveries occurred among Medicaid recipients corresponding with the implementation of the PMH program. Further studies are needed to determine the specific impact of the PMH program on cesarean deliveries.
Bars in the Local Universe: An Observational Perspective
Creators: name: Erwin, Peter
Publisher: name: Zenodo
Year: 2023

description: I discuss our current understanding of the presence, size, and structure of bars in the local (z ~ 0) universe. In particular, I show how the frequency of bars in spiral galaxies is a strong function of stellar mass, peaking at a mass of ~ 109.7, and how failure to properly account for resolution effects can lead to strong biases in bar estimates. Bar size is a (bimodal) function of stellar mass, and an even stronger function of disk scale length. Boxy/peanut-shaped (BP) bulges -- the inner, vertically thickened parts of some bars -- are also a strong (and simple) function of stellar mass: they are universal at the high-mass end, but absent in the bars of low-mass galaxies. I also discuss new research on the radial structure of bars and sizes and abundances of the inner bars of double-barred galaxies.

description: A method to simulate orthotropic behaviour in thin shell finite elements is proposed. The approach is based on the transformation of shape function derivatives, resulting in a new orthogonal basis aligned to a specified preferred direction for all elements. This transformation is carried out solely in the undeformed state leaving minimal additional impact on the computational effort expended to simulate orthotropic materials compared to isotropic, resulting in a straightforward and highly efficient implementation. This method is implemented for rotation-free triangular shells using the finite element framework built on the Kirchhoff--Love theory employing subdivision surfaces. The accuracy of this approach is demonstrated using the deformation of a pinched hemispherical shell (with a 18° hole) standard benchmark. To showcase the efficiency of this implementation, the wrinkling of orthotropic sheets under shear displacement is analyzed. It is found that orthotropic subdivision shells are able to capture the wrinkling behavior of sheets accurately for coarse meshes without the use of an additional wrinkling model.

description: Objectives: To determine if maternal education and wealth status predicts maternal self-reported unknown HIV status among women in Kenya. Methods: Kenya Demographic Health Survey (KDHS) 2008 – 2009 was used to examine the association between unknown HIV status and education and wealth, controlling for age, place of residence, place of delivery, history of intimate violence, knowledge of prevention of mother to child transmission (PMTCT), and health decision-making. Results: 617 (21.8%) had unknown HIV status. Education was not associated with unknown HIV status. Only women in the richest wealth category reported less unknown HIV status. Home and private facility births, high PMTCT knowledge and antenatal care (ANC) visits significantly decreased likelihood of unknown HIV status in education and wealth status model. Rural residence significantly predicted unknown HIV status in education model. Conclusion: There is a need to improve PMTCT knowledge and services in rural areas, and to maximize counseling and testing through antenatal care visits.

description: Studies on fossil bone microbial communities are scarce; even fewer studies were performed in cave deposits. For our research, sediments and fossil bones were sampled, and the whole community 16S rRNA gene-based metabarcoding analyses were performed on samples from Muierilor and Ursilor caves, some of Romania’s most important archaeological and paleontological sites. Most of the identified taxa belong to Bacteria, with Proteobacteria, Acidobacteriota, Bacteroidota, and Actinobacteriota amongst the most abundant phyla in bone samples from both caves. The sediment samples presented similar composition, with Proteobacteria and Acidobacteriota being the most abundant phyla. The inferred bacteriomes indicated the presence of environment-specific bacteria, typical bone colonizers, and bacteria found in soils and decomposing human remains or archaeological profiles as well as phosphate-solubilizing and organotrophic bacteria. Diversity indices indicated a higher diversity in bone samples from Muierilor Cave than in Ursilor Cave samples and sediment samples from both caves. Environmental conditions, especially air relative humidity, were also considered in explaining the bacteriome diversity in different cave settings. These findings help to understand fossil bones’ deposition and degradation in various environmental conditions. Furthermore, this is the first attempt to relate microenvironments and bacteria to preserving fossil bones from caves.

description: The Operating Room (OR) is a clinical context in which interprofessional teams surgically intervene with the intention of improving the health of the patients they care for. Despite this, surgery is high risk, invasive and often volatile. The reality is that some patients die in the OR, an outcome which violates the care intention of the clinicians who work there. Using the narrative paradigm, this study explores the stories interprofessional team members shared about caring for patients who died intraoperatively. To appreciate the cultural climate in which these stories were rooted, a literature review of OR culture and theoretical analysis of master narratives was conducted. Using individual interviews, six perioperative clinicians were invited to share their stories: two Registered Nurses, one Registered Practical Nurse, two Surgeons and one Anesthetist. Two analytic approaches were used to authentically capture participant narratives: a narrative thematic approach and structural analysis. The structural analysis revealed the types of stories told—tragedies, romances, comedies and satires—while the thematic perspective elucidated participants’ experiences of intraoperative death and their interpretation of the impact of these experiences. These findings illustrated unique perspectives of intraoperative death, illuminating features which enhanced or deteriorated the experiences for clinicians and their teams. Examining results in tandem with master narratives highlighted prevalent cultural discourses which are held in tension by the clinicians who perpetuate them. Exploring these intersecting elements provides insight into implications for nursing practice, research, education and policy, with particular attention to interprofessional dynamics, staff support, and promoting a culture of resilience.

description: The stability, electronic and optical properties of single-walled carbon nanotubes (CNTs) and graphene noncovalently functionalized with free-base tetraphenylporphyrin (TPP) molecules is addressed by density functional theory calculations, including corrections to dispersive interactions. We study the TPP physisorption on 42 CNT species, particularly those with chiral indices ($n$,$m$), where $5 \leq n \leq 12$ and $0\leq m\leq n$. Our results show a quite strong $π$-$π$ interaction between TPP and the CNT surface, with binding energies ranging from 1.1 to 1.8 eV, where higher energies can be associated with increasing CNT diameters. We also find that the TPP optical absorptions would not be affected by the CNT diameter or chirality. Results for the TPP physisorption on graphene show a remarkable stability with binding energy of 3.2 eV, inducing a small redshift on the $π$-stacked TPP absorption bands. The strong graphene-TPP interaction also induces a charge transfer from TPP to graphene, indicating a $n$-type doping mechanism without compromising the graphene structure.

Kinship Care and Foster Care: A Comparison of Out-of-Home Placement from the Perspective of Child Abuse Experts in North Carolina
Creators: name: Darwiche, Sabrina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Background: Guided by federal and state regulations, children in North Carolina (NC) removed from their homes because of allegations of maltreatment are preferentially placed in kinship care. Kinship care’s definition is variable, with NC moving towards using the term to exclusively refer to a care arrangement in which the Department of Social Services (DSS) has taken custody of a child and placed them with a family member or friend, as opposed to foster care, in which a child in DSS custody is placed with a licensed foster parent previously unknown to that child. Although national research is inconsistent as to which form of placement leads to better outcomes for children, it appears that children in kinship care receive less formal support. Objectives: To investigate from the perspective of child abuse medical experts practicing in NC: 1) their understanding of the state’s kinship care system; 2) the health needs of children in kinship care vs. foster care; and, 3) how multidisciplinary stakeholders can better work together to serve children in kinship care. Methods: A mixed method design was used to conduct semi-structured interviews with child abuse medical providers. Data were coded with a team generated codebook and qualitative data were analyzed in ATLAS.ti 7.5.10. Conclusions: Major themes included: 1) providers have a foundational understanding of the NC kinship care system, but pockets of uncertainty mark this knowledge; 2) children in kinship care and foster care have equivalent, elevated health needs, but children in kinship care may not receive the same level of care, particularly in terms of their mental health; 3) social workers and medical professionals can make individual and structural changes to improve the ability of the multidisciplinary team to facilitate the health of children in kinship care compared to foster care.

However, elucidating the underlying mechanisms, governed by entangled degrees of freedom such as lattice, spin, orbit, and charge for solids or conformation, electric potentials, and ligands for proteins, has remained challenging. Techniques that allow for distinguishing between different contributions to these processes are hence urgently required. In this paper we demonstrate the application of scattering-type scanning near-field optical microscopy (s-SNOM) as a novel type of nano-probe for tracking transient states of matter. We introduce a sideband-demodulation technique that allows for probing exclusively the stimuli-induced change of near-field optical properties. We exemplify this development by inspecting the decay of an electron-hole plasma generated in SiGe thin films through near-infrared laser pulses. Our approach can universally be applied to optically track ultrafast/-slow processes over the whole spectral range from UV to THz frequencies.

description: A new set of laws of motion for turbulent jets propagating in an intergalactic medium characterized by a decreasing density is derived by applying conservation of momentum flux both in the classical and relativistic framework. Two characteristic features of radio-galaxies, such as oscillations and curvature, are modeled by a classical helicoidal jet. A third feature of a radio-galaxy, the appearance of knots, is explained as an effect due to the theory of images.

description: Smart Contracts are a technology that leverages blockchain to automate and secure transactions. They are commonly used to manage transaction fees and mining rewards within blockchain networks, and can be programmed to execute automated transactions based on predetermined conditions. The use of smart contracts offers numerous benefits for small and medium-sized enterprises, including reduced transaction costs, improved transparency and accountability, and enhanced security and efficiency. The deployment of smart contracts in a company can also lead to increased automation of transactions, further streamlining processes and reducing the potential for human error.

description: We give a stochastic model for the fragmentation phase of a snow avalanche. We construct a fragmentation-branching process related to the avalanches, on the set of all fragmentation sizes introduced by J. Bertoin. A fractal property of this process is emphasized. We also establish a specific stochastic equation of fragmentation. It turns out that specific branching Markov processes on finite configurations of particles with sizes bigger than a strictly positive threshold are convenient for describing the continuous time evolution of the number of the resulting fragments. The results are obtained by combining analytic and probabilistic potential theoretical tools.

description: This thesis addresses notions of personhood in Tweo Coldita, an indigenous community located on Coldita island (Chiloé). It addresses relationality, selfhood and autochthony by means of the Colditan notion of “viviente”, “a person who is living” in spaces between forest and tide. These spaces or “campos”, which Colditans strive to keep open, constitute a “lived world of confusion” from where the viviente emerges. Confusion describes how moving “borders” (environmental, social, temporal and of selfhood) tend to overlap, threatening to drive the viviente and its environment towards a lack of differentiation. To be a proper viviente is a constant struggle in a mythicized world. I argue that the latter’s confusing nature, along that of the vivientes themselves, can be elicited from a “mythical schema” stemming from a Chilote version of the Treng-Treng and Kay-Kay Vilú myth. In this narration, a catastrophe makes the sea and the lands clash, and a lonely, mad man is left in a submerged world. This resembles Tweo Colditans’ notions on confusion: colliding environmental elements growing over the campos and loneliness as a limit for the viviente, a person that is constantly menaced with being turned inwards and that must strive to relate to others and reproduce a world. Because of this mythification, a doubt lingers about the viviente’s origin. This doubt is reflected in the relationship with dwelling places, the campos, in the form of a confusion within that emerges as a feeling of “uncanniness”. I propose that the haunting of the uncanny in Tweo Coldita has to do with the problem of autochthony, the impossibility to fully belong, making the constitution of vivientes an impossible task. The viviente is constantly diluting into confusing selfhood through the very mythicized structuring of the world enacted from the campos. These Colditans notions allow to discuss relationality, personhood and the self, and recent descriptions of Chiloé as defined by the tradition/modernity dyad.
Semi-Discrete Formulations for 1D Burgers Equation

description: In this work we compare semi-discrete formulations to obtain numerical solutions for the 1D Burgers equation. The formulations consist in the discretization of the time-domain via multi-stage methods of second and fourth order: R_{11} and R_{22} Padé approximants, and of the spatial-domain via finite element methods: least-squares (MEFMQ), Galerkin (MEFG) and Streamline-Upwind Petrov-Galerkin (SUPG). Knowing the analytical solutions of the 1D Burgues equation, for different initial and boundary conditions, analyzes were performed for numerical errors from L_{2} and L_{\infinity} norm. We found that the R_{22} Padé approximants, added to the MEFMQ, MEFG, and SUPG formulations, increased the region of convergence of the numerical solutions, and showed greater accuracy when compared to the solutions obtained by the R_{11} Padé approximants. We note that the R_{22} Padé approximants softened the oscillations of the numerical solutions associated to the MEFG and SUPG formulations.

Reproductive Health Needs in Complex Humanitarian Emergencies: an Analysis of Medecins Sans Frontieres' Programs in the Democratic Republic of the Congo
Creators: name: Chiang, Charlotte
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Objectives: 1) To examine reproductive health needs in the Democratic Republic of the Congo’s (DRC) most severe conflict zones; 2) to examine the role Medecins Sans Frontieres (MSF) plays in addressing these needs in the region. Methods: Data were collected through conducting literature searches, reading books written on MSF, and thoroughly navigating the MSF website in order to find relevant pod-casts, articles, press releases, and publications. Findings were analyzed using principles outlined in the "Inter-Agency Field Manual on Reproductive Health in Refugee Situations" published by the Inter-agency Working Group on Reproductive Health in Crises. Results: Of the six analysis criteria against which it was judged, MSF demonstrated commitment to all, though with varying degree. Its work as an organization, as well as projects specific to the DRC, demonstrates particularly high quality of care and attention to human rights. Conclusions: Though organizations such as MSF are crucial to providing essential maternal health services during Complex Humanitarian Emergencies (CHE), they cannot always overcome political instability and violence, and often fail to build long lasting health systems. Their work should be complemented with additional awareness campaigns and support from local NGOs.

description: Background: Oral nicotine pouches (NPs) are smokeless, tobacco-free products that have a potential role in tobacco harm reduction strategies. Methods: In a cross-sectional study in Sweden/Denmark, several recognised biomarkers of potential harm (BoPHs) linked to smoking-related diseases/their initiating biological processes, and biomarkers of exposure (BoEs) to tobacco/tobacco smoke toxicants were compared among exclusive adult users of Velo NPs and current/former/never smokers. Over 24 h, participants used their usual product (Velo NP or cigarette) as normal, and BoEs/BoPHs were assessed via blood/24-h urine/exhaled breath/physiological assessments. Results: Among the primary endpoints, total NNAL (16.9 ± 29.47 vs 187.4 ± 228.93 pg/24 h), white blood cell count (5.59 ± 1.223 vs 6.90 ± 1.758 × 109/L), and COHb (4.36 ± 0.525 vs 8.03 ± 2.173% saturation) were significantly lower among Velo users than among smokers (91%, 19% and 46% lower, respectively, all P < 0.0001), while fractional exhaled NO, previously shown to be lower in smokers, was significantly higher (23.18 ± 17.909 vs 11.20 ± 6.980 ppb) among Velo users (107% higher, P < 0.0001). Furthermore, sICAM-1 tended to be lower (185.9 ± 42.88 vs 204.5 ± 64.85 ng/mL) among Velo users than smokers (9% lower). Several secondary endpoints, including six BoEs (3-HPMA (246.7 ± 91.07 vs 1165.7 ± 718.35 μg/24 h), 3-OH-B[a]P (82.4 ± 217.58 vs 258.3 ± 190.20 pg/24 h), HMPMA (135.1 ± 77.85 vs 368.8 ± 183.15 μg/24 h), MHBMA (0.22 ± 0.166 vs 3.39 ± 2.943 μg/24 h), S-PMA (0.10 ± 0.059 vs 3.53 ± 2.736 µg/24 h) and total NNN (7.5 ± 24.84 vs 9.7 ± 5.93 ng/24 h)), were significantly lower among Velo users (78.8%, 68.1%, 63.4%, 93.5%, 97.2% and 22.7% lower, respectively, P < 0.0001–0.0011), while total nicotine equivalents was significantly higher among Velo users (22.6 ± 12.69 vs 12.1 ± 7.92 mg/24 h, P < 0.0001), although Velo user levels are comparable to those previously reported among oral tobacco users, and Velo user and smoker mean levels were similar in Denmark. Conclusion: As compared with smokers, exclusive users of Velo NPs have significantly less exposure to tobacco toxicants and more favourable BoPHs associated with initiating biological processes of smoking-related diseases.
