Self-Reported Delays in Care Do not Predict Increased Mortality in a Cohort of Community-Dwelling Elders
Creators: name: Rupper, Randall W., M.D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Background: Self-reporting of delayed care is a common measure of access to healthcare. The relationship of such reports to worsened health outcomes is often assumed, but few studies have tested this longitudinal connection. Objective: To determine whether self-reports of delayed care predict increased mortality among community-dwelling elderly. Design: 3-year longitudinal retrospective cohort study. Setting: A five county area of North Carolina. Participants: 4,162 randomly sampled individuals age 65 and older. Measurements: The outcome was the proportional hazard ratio (HR) for death stratified by the factor of interest, baseline self-reports of delayed or foregone care. Control variables included predisposing, enabling, and need factors influencing care seeking and/or mortality. Results: Of 3,964 eligible participants reporting, 61% never, 27% once in awhile, and 12% quite often delayed care. 13% of participants died during the study period. Older age, male gender, lower income, less education, lack of supplemental insurance, less social support, more depression, more severe chronic disease, smoking, and worse self-rated health predict increased mortality (pvalues<.0l). Of these, age, lower income, less education, lack of supplemental insurance, less social support, worse self-rated health, and more depression were significantly associated with more self-reported delays in care. In both an unadjusted and fully adjusted survival model, 3-year mortality rates did not differ among cohorts reporting varying degrees of delayed care. Conclusion: Among community dwelling elders, self-reports of delayed care did not predict increased 3-year mortality rates. These results raise questions about self-reporting of delayed or foregone care as a measure of access to the healthcare system.

On Operator-Valued Bi-Free Distributions

subject: 46L54, 46L53

description: In this paper, operator-valued bi-free distributions are investigated. Given a subalgebra $D$ of a unital algebra $B$, it is established that a two-faced family $Z$ is bi-free from $(B, B^{\mathrm{op}})$ over $D$ if and only if certain conditions relating the $B$-valued and $D$-valued bi-free cumulants of $Z$ are satisfied. Using this, we verify that a two-faced family of matrices is $R$-cyclic if and only if they are bi-free from the scalar matrices over the scalar diagonal matrices. Furthermore, the operator-valued bi-free partial $R$-, $S$-, and $T$-transforms are constructed. New proofs of results from free probability are developed in order to facilitate many of these bi-free results.

Pre-Exposure Chemoprophylaxis for Prevention of HIV Infection: The global obligation to provide affordable pre-exposure preventative medications
Creators: name: Massengale, Kelley E. C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: The fact that during 2009 an estimated 2.6 million people were infected with human immunodeficiency virus (HIV) indicates additional methods for preventing HIV infections, including an effective pre-exposure chemoprophylaxis, are sorely needed. Promising attempts at developing a pre-exposure chemoprophylaxis for HIV have included the development of a microbicide gel and use of oral antiretroviral medication. Now is not too early to begin planning for resource allocation and to explore the ethical arguments in favor of global distribution of pre-exposure chemoprophylaxis for people who have no other options for HIV prevention. People living in developed and developing countries alike are likely to benefit from pre-exposure chemoprophylaxis as an individualized option to gain control over their own risks for developing HIV infections. Whether individual risk factors for HIV exposure include not knowing a sexual partner’s HIV status, a serodiscordant relationship, having multiple sexual partners, substance abuse, injection drug use, or occupational exposure through commercial sex work, obtainable pre-exposure chemoprophylaxis may prove to be the only method available for those at risk who have no other options for HIV prevention. A good first step for governments, non-governmental organizations, insurance companies, and healthcare providers to take is to consider the ethical arguments promoting the global distribution of pre-exposure chemoprophylaxis for HIV. This paper will explore the subpopulations likely to benefit from pre-exposure chemoprophylaxis for HIV, the arguments for and against global distribution of pre-exposure chemoprophylaxis, ethical considerations for distribution, and leadership guidance for public health in a new era of HIV prevention.

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We show possibility of the Plane Couette (PC) flow instability for Reynolds number Re>Reth=140. This new result of the linear hydrodynamic stability theory is obtained on the base of refusal from the traditionally used assumption on longitudinal periodicity of the disturbances along the direction of the fluid flow. We found that earlier existing understanding on the linear stability of this flow for any arbitrary large Reynolds number is directly related with an assumption on the separation of the variables of the spatial variability for the disturbance field and their periodicity in linear theory of stability. By the refusal from the pointed assumptions also for the Plane Poiseuille (PP) flow, we get a new threshold Reynolds value Reth=1040 that with 4% accuracy agrees with the experiment contrary to more than 500% discrepancy for the earlier known estimate Reth=5772 obtained in the frame of the linear theory but when using the "normal" disturbance form (S. A. Orszag, 1971).

Prevention of HIV/AIDS on the Home Front: Lessons Learned from our Global Neighbors
Creators: name: Ozaki, Daniel A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: The Human Immunodeficiency Virus, or HIV, epidemic represents one of the greatest public health challenges of the late 20th and now, early 21st century. According to the World Health Organization (2013), approximately 70 million people have been infected with HIV worldwide since the beginning of the epidemic and approximately 35 million people have perished. To date, great strides have been made therapeutically in the creation and distribution of HIV antiretrovirals (ARVs) that can keep viral levels low in the infected individual thus prolonging his/her life expectancy; however, in the absence of an effective vaccine, prevention still is the most viable method of combating the pandemic. As the greatest burden of the epidemic lies outside the United States, there have been a plethora of prevention programs that have been launched internationally to combat HIV infection. Programs offering voluntary counseling and testing, condom distribution, needle/syringe exchange, and antiretroviral distribution have shown success in reducing HIV incidence in a wide range of geographic locations, including developing countries, where they have been launched. While many of the concepts of the programs are not new to the United States; to date, most prevention efforts have been sporadic and focused at the state or local level as opposed to federally-funded, evidence-based prevention programs on a national scale. Utilizing information gleaned from other countries, and especially developing countries, a series of recommendations are presented for how to improve HIV prevention efforts in the United States. Barriers to implementation of these ideas are also discussed and methods to overcome these barriers are presented, including social marketing, a field of study and practice that can be potentially utilized to launch prevention efforts in the communities of individuals that are most at risk.
Predictions on the second-class current decays $τ^{-}\toπ^{-}η^{(\prime)}ν_τ$

description: We analyze the second-class current decays $τ^{-}\toπ^{-}η^{(\prime)}ν_τ$ in the framework of Chiral Perturbation Theory with resonances. Taking into account $π^{0}$-$η$-$η^{\prime}$ mixing, the $π^{-}η^{(\prime)}$ vector form factor is extracted, in a model-independent way, using existing data on the $π^{-}π^{0}$ one. For the participant scalar form factor, we have considered different parameterizations ordered according to their increasing fulfillment of analyticity and unitarity constraints. We start with a Breit-Wigner parameterization dominated by the $a_{0}(980)$ scalar resonance and after we include its excited state, the $a_{0}(1450)$. We follow by an elastic dispersion relation representation through the Omnès integral. Then, we illustrate a method to derive a closed-form expression for the $π^{-}η$, $π^{-}η^{\prime}$ (and $K^{-}K^{0}$) scalar form factors in a coupled-channels treatment. Finally, predictions for the branching ratios and spectra are discussed emphasizing the error analysis. An interesting result of this study is that both $τ^{-}\toπ^{-}η^{(\prime)}ν_τ$ decay channels are promising for the soon discovery of second-class currents at Belle-II. We also predict the relevant observables for the partner $η^{(\prime)}_{\ell 3}$ decays, which are extremely suppressed in the Standard Model.

description: Photocount statistics are an important tool for the characterization of electromagnetic fields, especially for fields with an irrelevant phase. In the microwave domain, continuous rather than discrete measurements are the norm. Using a novel approach, we recover discrete photon statistics from the cumulants of a continuous distribution of field quadrature measurements. The use of cumulants allows the separation between the signal of interest and experimental noise. Using a parametric amplifier as the first stage of the amplification chain, we extract useful data from up to the sixth cumulant of the continuous distribution of a coherent field, hence recovering up to the third moment of the discrete statistics associated with a signal with much less than one average photon.

Psychosocial Harms of Ductal Carcinoma in Situ Diagnosis and Treatment: A Systematic Review
Creators: name: Rearick, William
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Background: Each year in the United States, about 54,000 women are diagnosed with ductal carcinoma in situ (DCIS). Most diagnoses are by screening mammography in asymptomatic women. Many women have small, low-grade lesions, and almost all are treated surgically. More than 50% of these women may be overdiagnosed. Objective: To characterize psychosocial harms of DCIS diagnosis and treatment. Understanding these harms might facilitate development of interventions to improve wellbeing in these women. Data Sources: MEDLINE, CINAHL, PsycINFO and Cochrane Library databases, reference lists, forward citation searches Study Selection: Studies evaluating psychosocial outcomes in adult women diagnosed and/or treated for DCIS were included. Data Extraction: Two reviewers assessed study quality using methods adapted from the United States Preventive Services Task Force and the Clinical Skills Assessment Programme. One reviewer abstracted data, and a second reviewer verified abstraction. Data Synthesis: Fifteen articles describing eight studies met inclusion criteria, including four prospective cohort studies, two cross-sectional studies, and two qualitative studies. Key findings include a clinically significant impact on quality of life in the first six months after diagnosis, and intrusive thoughts and fear of recurrence that commonly persist at least 18-24 months. Limitations: We include only a subset of the potential harms of DCIS. We do not consider studies of invasive breast cancers. Threats to internal validity included lack of power analyses, multiple statistical comparisons, and non-validated instruments. Few studies have assessed effects of diagnosis (labeling) independent of treatment. No studies meeting eligibility criteria have assessed interventions to improve wellbeing. Conclusions: Women with DCIS appear to experience clinically significant effects on wellbeing. Additional good quality longitudinal studies are needed to characterize the nature and burden of psychosocial harms experienced by these women.

Physician Opinion of the U.S. Health Care System: A Systematic Review
Creators: name: Lykes, John B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This systematic review of published research on physician attitudes toward health reform begins with a brief analytical illustration of organized medicine as an important political influence, before moving to a structured, critical appraisal of opinion literature. The systematic review identified 15 studies, culled from 1968-2009, which met quality standards. Physicians overall tended to be dissatisfied with the system and believed that everyone should have access to care, but they have yet to achieve consensus as to the best course for reform. Primary care, hospital-based, salaried, and urban physicians were more likely to support single payer plans. Meanwhile, surgeons, specialists, AMA members, office-based, and private practice physicians appear more likely to choose retention of the current system or a non-single-payer alternative, such as tax credits or health savings accounts. Several problems dog the literature throughout and limit our ability to draw conclusions, including: question wording problems, non-response bias, limited study populations, the absence of key variables, and a limited ability to track trends.

description: We have obtained a low optical inhomogeneous linewidth of 25 MHz in the stoichiometric rare earth crystal EuCl3 .6H2 O by isotopically purifying the crystal in 35 Cl. With this linewidth, an important limit for stoichiometric rare earth crystals is surpassed: the hyperfine structure of 153Eu is spectrally resolved, allowing the whole population of 153Eu3+ ions to be prepared in the same hyperfine state using hole burning techniques. This material also has a very high optical density and can have long coherence times when deuterated. This combination of properties offers new prospects for quantum information applications. We consider two of these, quantum memories and quantum many body studies. We detail the improvements in the performance of current memory protocols possible in these high optical depth crystals, and how certain memory protocols, such as off-resonant Raman memories, can be implemented for the first time in a solid state system. We explain how the strong excitation-induced interactions observed in this material resemble those seen in Rydberg systems, and describe how these interactions can lead to quantum many-body states that could be observed using standard optical spectroscopy techniques.

Behavioral Health Crisis Care: Moving Towards Less Dependence on the Emergency Department
Creators: name: Colangelo, Henry
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Behavioral health care in the United States underwent a significant transformation in the latter half of the 20th century with a mass movement towards deinstitutionalization. Since then, we have seen community mental health services struggle to adequately care for the growing number of individuals with serious mental illness and substance abuse. As a result, emergency departments have shouldered a large proportion of the increased need for behavioral health services. In many communities, the ED may be the only place that an individual in crisis can go to for psychiatric evaluation at all hours of the day. With the recent passage of health reform and a focus on studying innovative care models, new behavioral health facilities that provide an array of services have begun to emerge. These novel facilities aim to be an alternative to the emergency room for individuals in mental health or substance abuse crisis. The purpose of this Master's Paper is to explore the setting of psychiatric emergency care and its relationship to the emergency department, as well as report on the experience of a novel psychiatric crisis and assessment facility in Wake County, North Carolina. The first part of this paper is a systematic review of the literature on interventions or strategies for reducing patient transfers from psychiatric crisis centers to the ED, experiences with ED transfers in other settings, and the process of "medical clearance" of psychiatric patients in emergency settings. The review demonstrated that there is a significant gap in the literature pertaining to patient transfers from psychiatric crisis centers to the ED. In addition, a majority of the reviewed studies on "medical clearance" of psychiatric patients suggested that routine laboratory testing is unnecessary and may be overused. Furthermore, they acknowledged the need for more prospective studies of medical clearance protocols for this patient population. Following the systematic literature review, this paper continues with an original manuscript that presents the results of a descriptive study of individuals who presented to the Wakebrook Crisis and Assessment facility and were subsequently transferred to a medical ED. The results of this study demonstrated an overall downward trend in ED transfer rate since the initiation of a co-located primary care team but also identified a subpopulation of potentially avoidable transfers that occurred. This study is unique in that it describes a population of individuals who presented to a psychiatric crisis center but were later seen in a medical ED for either medical or psychiatric reasons. While it is a preliminary descriptive analysis, it provides a path for future research into the effectiveness of these novel facilities in preventing unnecessary ED visits and improving patient outcomes.

description: The biological function of proteins is encoded in their structure and expressed through the mediation of their dynamics. Local fluctuations are known to initiate biologically relevant pathways as they cooperatively enhance the dynamics in specific regions in the protein. Those biologically active regions provide energetically-comparable conformational states that can be trapped by a reacting partner. We analyze this mechanism as we calculate the dynamics of monomeric and dimerized HIV protease, and free Insulin Growth Factor II Receptor (IGF2R) domain 11 and its IGF2R:IGF2 complex. We adopt a newly developed coarse-grained model, the Langevin Equation for Protein Dynamics (LE4PD), which predicts dynamical relevant mechanisms with high accuracy. Both simulation-derived and experimental NMR conformers are the input structural ensembles for the LE4PD. The use of the experimental NMR conformers requires minimal computational resources.

Quantum Recurrences in a One-Dimensional Gas of Impenetrable Bosons

description: It is well-known that a dilute one-dimensional (1D) gas of bosons with infinitely strong repulsive interactions behaves like a gas of free fermions. Just as with conduction electrons in metals, we consider a single-particle picture of the resulting dynamics, when the gas is isolated by enclosing it into a box with hard walls and preparing it in a special initial state. We show, by solving the nonstationary problem of a free particle in a 1D hard-wall box, that the single-particle state recurs in time, signaling the intuitively expected back-and-forth motion of a free particle moving in a confined space. Under suitable conditions, the state of the whole gas can then be made to recur if all the particles are put in the same initial momentum superposition. We introduce this problem here as a modern instance of the discussions giving rise to the famous recurrence paradox in statistical mechanics: on one hand, our results may be used to develop a poor man's interpretation of the recurrence of the initial state observed [T. Kinoshita et al, Nature 440, 900 (2006)] in trapped 1D Bose gases of cold atoms, for which our estimated recurrence time is in fair agreement with the period of the oscillations observed; but this experiment, on the other hand, has been substantially influential on the belief that an isolated quantum many-body system can equilibrate as a consequence of its own unitary nonequilibrium dynamics. Some ideas regarding the latter are discussed.

description: The Institute of Medicine's 1988 report, The Future of Public Health, proposes that "[p]ublic health is what we, as a society, do collectively to assure the conditions for people to be healthy" (IOM, 1988, p.19). The scope of public health has expanded from the challenges posed by the control of contagion and spread of infectious disease to current population health improvement and prevention efforts informed by the social determinants of health (IOM, 2003). Law is a major component of public health practice for population health improvement (Goodman, 2006; IOM, 2011). Traditional public health laws were aimed to prevent communicable disease epidemics and to assure clean water and air (Epstein, 2003). As the public's health is challenged by chronic disease relating to environmental and behavioral factors, including obesity and tobacco usage, coupled with the understanding of the significance of social determinants, the role of public health law has expanded (Gostin, 2008b). This paper examines law as a driver of population health with consideration of Health In All Policies (HIAP) and Health Impact Assessments (HIA) as emerging public health legal tools. Recommendations are suggested to strengthen public health professionals' access to the appropriate and informed use of law to improve population health.

description: We explore several novel LHC signatures arising from quark or lepton flavor violating couplings in the Higgs sector, and we constrain such couplings using LHC data. Since the largest signals are possible in channels involving top quarks or tau leptons, we consider in particular the following flavor violating processes: (1) $pp \to thh$ (top plus di-Higgs final state) arising from a dimension six coupling of up-type quarks to three insertions of the Higgs field. We develop a search strategy for this final state and demonstrate that detection is possible at the high luminosity LHC if flavor violating top--up--Higgs couplings are not too far below the current limit. (2) $pp \to tH^0$, where $H^0$ is the heavy neutral CP-even Higgs boson in a two Higgs doublet model (2HDM). We consider the decay channels $H^0 \to tu, WW, ZZ, hh$ and use existing LHC data to constrain the first three of them. For the fourth, we adapt our search for the $thh$ final state, and we demonstrate that in large regions of the parameter space, it is superior to other searches, including searches for flavor violating top quark decays ($t \to hq$). (3) $H^0 \to τμ$, again in the context of a 2HDM. This channel is particularly well motivated by the recent CMS excess in $h \to τμ$, and we use the data from this search to constrain the properties of $H^0$.

description: The kinetic energy of a star in orbit about a supermassive black hole is a significant fraction of its rest mass energy when its periapse is comparable to its tidal radius. Upon its destruction, a fraction of this energy is extracted and injected into the stellar debris, half of which becomes unbound from the black hole, with the fastest material moving at $\sim 0.03 c$. In this paper, we present a formalism for determining the fate of these unbound debris streams (UDSs) as they depart from the black hole and interact with the surrounding gas. As the density and velocity varies along the length of a UDS, we find that hydrodynamical drag quickly shapes UDSs into loop-like structures, with the densest portions of the streams leading portions of lower density. As UDSs travel outwards, their drag against the ISM increases quadratically with distance, which causes UDSs to deposit their momentum and energy into the ambient medium before the surrounding shocked ISM has a chance to cool. This sudden injection of $\sim 10^{50}$ erg into the ambient medium generates a Sedov-like unbound debris remnant (UDR) that mimics supernova remnants (SNRs) in energetics and appearance, accelerates particles which will produce cosmic rays and synchrotron emission, and provides momentum feedback into the molecular clouds surrounding a black hole. We estimate that a few of these UDRs might be present within a couple degrees of the Galactic Center masquerading as SNRs, and that the UDR scenario is a plausible explanation for Sgr A East.

Prevalence of ADHD Diagnosis and Treatment in African-American Children and Adolescents: A Systematic Review of the Literature
Creators: name: Wilson, Crystal

description: Purpose: To systematically review the literature to determine 1) the diagnostic and 2) treatment prevalence of attention deficit hyperactivity disorder among African American youth and compare the prevalence to Caucasian children and adolescents. Methods: Medline, Psychinfo, and Web of Science databases were searched from 1994- present for cross-sectional studies, cohort, non-randomized clinical trials, and metaanalyses that contained information regarding the diagnostic prevalence or prevalence of treatment for ADHD and compared African-Americans children and/or adolescents with Caucasian children and/or adolescents,. The author independently assessed studies for inclusion and quality. Results: 10 studies met inclusion and quality criteria for diagnosis and/or treatment and thus received detailed evaluation. Four studies specifically compared prevalence of an ADHD diagnosis between African-Americans and Caucasians while 9 studies specifically addressed treatment rates for ADHD among different ethnic subgroups. Three of the four (7 5%) of the articles examining diagnostic prevalence demonstrated there was no significant difference in the likelihood of being diagnosed with ADHD between Caucasian American and African-Americans children. Of the articles examining treatment prevalence, seven of the nine (71.4%) articles demonstrated African-Americans were less likely than Caucasian Americans to receive ADHD medications. Of note, other disparities in diagnosis and treatment of ADHD such as regional and health insurance factors were noted. Conclusions: Overall, it appears that disparities do exist in regards to ADHD treatment but not in diagnosis between African American and Caucasian youth. In addition to the need for higher quality, population-based studies that examine the disparate relationship between ADHD recognition and treatment in African American youth, further research should be dedicated to examining the factors that affect ADHD treatment rates in this group. Parental views and differential response to subtypes of ADHD treatment may play roles in this disparity.

description: Motivated by applications in economics and finance, in particular to the modeling of limit order books, we study a class of stochastic second-order PDEs with non-linear Stefan-type boundary interaction. To solve the equation we transform the problem from a moving boundary problem into a stochastic evolution equation with fixed boundary conditions. Using results from interpolation theory we obtain existence and uniqueness of local strong solutions, extending results of Kim, Zheng and Sowers. In addition, we formulate conditions for existence of global solutions and provide a refined analysis of possible blow-up behavior in finite time.

description: We have collected UVES-FLAMES high-resolution spectra for a sample of 6 asymptotic giant branch (AGB) and 13 red giant branch (RGB) stars in the Galactic globular cluster M62 (NGC6266). Here we present the detailed abundance analysis of iron, titanium, and light-elements (O, Na, Al and Mg). For the majority (5 out 6) of the AGB targets we find that the abundances, of both iron and titanium, determined from neutral lines are significantly underestimated with respect to those obtained from ionized features, the latter being, instead, in agreement with those measured for the RGB targets. This is similar to recent findings in other clusters and may suggest the presence of Non-Local Thermodynamical Equilibrium (NLTE) effects. In the O-Na, Al-Mg and Na-Al planes, the RGB stars show the typical correlations observed for globular cluster stars. Instead, all the AGB targets are clumped in the regions where first generation stars are expected to lie, similarly to what recently found for the AGB population of NGC6752. While the sodium and aluminum abundance could be underestimated as a consequence of the NLTE bias affecting iron and titanium, the used oxygen line does not suffer from the same effects and the lack of O-poor AGB stars therefore is solid. We can thus conclude that none of the investigated AGB stars belong to the second stellar generation of M62. We also find a RGB star with extremely high sodium abundance ([Na/Fe] = +1.08 dex).

description: After physicians complete their residency training, they are expected to prepare for board certification. In the field of obstetrics and gynecology, the American Board of Obstetrics and Gynecology (ABOG) is an independent, non-profit organization that certifies obstetricians and gynecologists in the United States. ABOG provides a list of subjects that are included in the certification examinations. The topics include a section on "Office Practice Preventive/Primary care." This section contains twenty-eight topics designated as areas that the obstetrician-gynecologist is responsible to cover. Therefore, we are proposing to focus on the educational objectives presented by the Residency Review Committee, which are included as topics for the American Board of Obstetrics and Gynecology for specialty board certification, in order to provide training in primary care to optimize patient care. This paper will provide the background and context for the proposed program. The goals and objectives to approach primary care training and implementation will be delineated. The evaluation design and dissemination plan will also be included. The paper will conclude with a summary of the proposal and broader recommendations for the primary care plan in Obstetrics and Gynecology training.
