Improving the Quality of HIV Prevention in the United States: The Leadership Role of the Centers for Disease Control and Prevention from 1981 through 2014

description: For more than 30 years, the epidemic caused by transmission of the human immunodeficiency virus (HIV), which causes acquired immune deficiency syndrome (AIDS), has touched the lives of millions of people throughout the United States and around the world. From the early 1980s through the mid-1990s, medical treatments for HIV spurred high hopes for extending the lives of HIV patients. But those hopes were dashed again and again. From the mid-1990s forward, many people around the world, including in the United States, have diminished the health threat posed by HIV by taking a combination of drugs that boosts the immune system and reduces the measurable amount of HIV in blood. Ever since the first published report about what would later be defined as HIV/AIDS, the Centers for Disease Control and Prevention (CDC), which is part of the U.S. Government's Department of Health and Human Services, has played a prominent role in developing and supporting HIV prevention globally. In the United States, this leadership has included working with other national public health institutions to characterize what constitutes a public health system and promulgate guidelines for assessing the performance of public health departments. It has also included funding public health departments, universities, research communities, community-based organizations, and other partners in HIV prevention in order to improve HIV prevention (e.g., reduce risk behaviors associated with HIV transmission). Noteworthy examples of the CDC's leadership in improving HIV prevention in the United States from 1981 through 2014 include funding HIV/AIDS testing, funding HIV prevention research, disseminating research findings via peer-reviewed journals, and funding a network of capacity-building assistance that includes online training, classroom training, and pertinent documents (e.g., implementation manuals, evaluation manuals). This paper summarizes the CDC's role in HIV prevention in the United States. This paper has three objectives. One, relate the CDC's leadership role in improving HIV prevention to "the 10 Essential Public Health Services" ("The 10 Essential Public Health Services: An Overview, 2014). Two, provide examples of how HIV prevention work performed by the CDC, health departments, and others has revealed ongoing health disparities. Three, state 10 recommendations for CDC-led improvement of HIV prevention that focus specifically on young black gay, bisexual, and other men who have sex with men-whom HIV/AIDS surveillance data indicate are at highest risk for acquiring HIV in the United States.

description: Unexpected structure in images of astronomical sources often presents itself upon visual inspection of the image, but such apparent structure may either correspond to true features in the source or be due to noise in the data. This paper presents a method for testing whether inferred structure in an image with Poisson noise represents a significant departure from a baseline (null) model of the image. To infer image structure, we conduct a Bayesian analysis of a full model that uses a multiscale component to allow flexible departures from the posited null model. As a test statistic, we use a tail probability of the posterior distribution under the full model. This choice of test statistic allows us to estimate a computationally efficient upper bound on a p-value that enables us to draw strong conclusions even when there are limited computational resources that can be devoted to simulations under the null model. We demonstrate the statistical performance of our method on simulated images. Applying our method to an X-ray image of the quasar 0730+257, we find significant evidence against the null model of a single point source and uniform background, lending support to the claim of an X-ray jet.

description: A Research Object (RO) provides a machine-readable mechanism to communicate the diverse set of digital and real-world resources that contribute to an item of research. The aim of an RO is to replace traditional academic publications of static PDFs, to rather provide a complete and structured archive of the items (such as people, organisations, funding, equipment, software etc) that contributed to the research outcome, including their identifiers, provenance, relations and annotations. This is increasingly important as researchers now rely heavily on computational analysis, yet we are facing a reproducibility crisis as key components are often not sufficiently tracked, archived or reported. We propose Research Object Crate (or RO-Crate for short), an emerging lightweight approach to package research data with their structured metadata, based on schema.org annotations in a formalized JSON-LD format that can be used independent of infrastructure to encourage FAIR sharing of reproducible datasets and analytical methods.

description: Many partial identification problems can be characterized by the optimal value of a function over a set where both the function and set need to be estimated by empirical data. Despite some progress for convex problems, statistical inference in this general setting remains to be developed. To address this, we derive an asymptotically valid confidence interval for the optimal value through an appropriate relaxation of the estimated set. We then apply this general result to the problem of selection bias in population-based cohort studies. We show that existing sensitivity analyses, which are often conservative and difficult to implement, can be formulated in our framework and made significantly more informative via auxiliary information on the population. We conduct a simulation study to evaluate the finite sample performance of our inference procedure and conclude with a substantive motivating example on the causal effect of education on income in the highly-selected UK Biobank cohort. We demonstrate that our method can produce informative bounds using plausible population-level auxiliary constraints. We implement this method in the R package selectioninterval.

Inevitable Power-law Behavior of Isolated Many-Body Quantum Systems and How It Anticipates Thermalization

description: Despite being ubiquitous, out-of-equilibrium quantum systems are much less understood than systems at equilibrium. Progress in the field has benefited from a symbiotic relationship between theoretical studies and new experiments on coherent dynamics. The present work strengthens this connection by providing a general picture of the relaxation process of isolated lattice many-body quantum systems that are routinely studied in experiments with cold atoms, ions traps, and nuclear magnetic resonance. We show numerically and analytically that the long-time decay of the probability for finding the system in its initial state necessarily shows a power-law behavior $\propto t^{ - γ}$. This happens independently of the details of the system, such as integrability, level repulsion, and the presence or absence of disorder. Information about the spectrum, the structure of the initial state, and the number of particles that interact simultaneously is contained in the value of $γ$. From it, we can anticipate whether the initial state will or will not thermalize.

description: We show that the mathematical structures in a recent work of Bultinck-Mariena-Williamson-Sahinoglu-Haegemana-Verstraete are the same as those of flat symmetric bi-unitary connections and the tube algebra in subfactor theory. More specifically, a system of flat symmetric bi-unitary connections arising from a subfactor with finite index and finite depth satisfies all their requirements for tensors and the tube algebra for such a subfactor and the anyon algebra for such tensors are isomorphic up to the normalization constants. Furthermore, the matrix product operator algebras arising from tensors corresponding to possibly non-flat symmetric bi-unitary connections are isomorphic to those arising from flat symmetric bi-unitary connections for subfactors.

description: We prove the existence of weak solutions to a viscoelastic phase separation problem in two space dimensions. The mathematical model consists of a Cahn-Hilliard-type equation for two-phase flows and the Peterlin-Navier-Stokes equations for viscoelastic fluids. We focus on the case of a polynomial-like potential and suitably bounded coefficient functions. Using the Lagrange-Galerkin finite element method complex behavior of solution for spinodal decomposition including transient polymeric network structures is demonstrated.

description: We report the first test of isotropy of the Universe in the matter dominated epoch using the Lyman-$α$ forest data from the high redshift quasars ($z>2$) from SDSS-III BOSS-DR9 datasets. Using some specified data cuts, we obtain the probability distribution function (PDF) of the Lyman-$α$ forest transmitted flux and use the statistical moments of the PDF to address the isotropy of the Universe. In an isotropic Universe one would expect the transmitted flux to have consistent statistical characteristics in different parts of the sky. We trisect the total survey area of 3275 ${\rm deg}^2$ along the galactic latitude and using quadrant convention. We also make three subdivisions in the data for three different signal-to-noise-ratios (SNR). Finally we obtain and compare the statistical moments in the mean redshifts of 2.3, 2.6 and 2.9. We find, that the moments from all patches agree at all redshifts and at all SNRs, within 3$σ$ uncertainties. Since Lyman-$α$ transmitted flux directly maps the neutral hydrogen distribution in the inter galactic medium (IGM), our results indicate, within the limited survey area and sensitivity of the data, the distribution of the neutral hydrogen in the Universe is consistent with isotropic distribution. We should mention that we report few deviations from isotropy in the data with low statistical significance. Increase in survey area and larger amount of data are needed to make any strong conclusion about these deviations.

Primary screening for the risk of opioid addiction using the opioid risk tool (ORT) in orthopedic surgical patients
Creators: name: Pugliese, Kacey
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of project: Opioid addiction has plagued patients nationally, with tens of thousands of deaths attributed to opioid misuse, including illicit and prescription opioids, each year. Orthopedic procedures incline to result in increased postoperative musculoskeletal pain which is commonly treated with prescription opioid medications.Methodology: A retrospective and prospective quality improvement project was conducted in an orthopedic ambulatory practice of Sports Medicine with the aim to prevent future cases of opioid misuse and abuse. The Opioid Risk Tool (ORT), originally created by Webster and Webster to screen patients with chronic non-malignant pain, was implemented to preoperatively screen adults, ages 18 to 65, undergoing an elective orthopedic surgical procedure. Participants who scored moderate- or high-risk for future opioid misuse were referred to an anesthesia provider for further discussion of their postoperative analgesia treatment plans. Post-implementation, an anonymous survey was sent to the participating providers. Results: A total of 21 participants were screened with the Opioid Risk Tool. Four patients screened as moderate-risk for future opioid addiction and all four were referred to, and seen by an anesthesia provider before their procedure. No patient screened as high-risk for opioid abuse. Pre-implementation, 11.54% of patients consented for an elective procedure were seen by an anesthesia provider preoperatively. Post-implementation, the number of patients seen by an anesthesia provider before their surgical procedure was 37.93%, with a computed increase of 26.39% (p-value = 0.0051). Implications for practice: The project provided contributive data for use of the tool in a population other than for which it was created. No differences in demographics were found to correlate with the higher risk of future opioid addiction. The positive feedback collected suggests that the screening process would be sustainable at the project site and can be used as a model for similar settings. Organizations could benefit by updating their policies or guidelines to include the use of the tool in provider preoperative screenings. Preoperative screening with the Opioid Risk Tool could prevent future instances of opioid addiction by appropriately referring patients at higher risk for opioid addiction, while aiding in reducing the economic burdens related to prescription opioid misuse.

description: Clearly, Honduras is a country in need. Because of this, many relief organizations target Honduras as a country to focus their relief efforts. Compassion Med International is an organization that strives to bring hope and healing where it is most needed. It shares the wisdom and vision of Nicholas de Torrente, the executive director of Doctors Without Borders, who is often quoted as saying: "We find out where conditions are the worst, the places others are not going,and that's where we want to be." In this paper I will set out to describe the conditions in Honduras, and show what needs are there. I am writing on behalf of a short term medical missions group called Compassion Med International (CMI), and will be performing a review of the literature with regard to short term medical missions, develop a program plan for CMI, and set up a framework for a program evaluation process.

description: Radio giant pulses provide a unique opportunity to study the pulsar radio emission mechanism in exquisite detail. Previous studies have revealed a wide range of properties and phenomena, including extraordinarily high brightness temperatures, sub-nanosecond emission features, and banded dynamic spectra. New measurements of giant pulse characteristics can help guide and test theoretical emission models. To this end, an extensive observation campaign has begun which will provide more than 500 hours on the Crab with a 34-meter antenna located in California, USA. The observations are being done as part of an educational outreach program called the Goldstone-Apple Valley Radio Telescope (GAVRT). This antenna has a novel wide bandwidth receiver which provides up to 8 GHz of instantaneous bandwidth in the range of 2.5 to 14 GHz. These observations will provide detailed information about the variability, amplitude distribution, and detailed frequency structure of radio giant pulses. In addition, a database of pulses from these observations and others of the Crab pulsar is being created which will simplify multiwavelength correlation analysis.

We further consider matrix-valued Gaussian fields twisted by an orthogonal, unitary or symplectic connection. In this case the isomorphisms involve traces of holonomies of the connection along random walk loops parametrized by boundary cycles of ribbon graphs.

description: Recent observations of Reticulum II have uncovered an overabundance of r-process elements, compared to similar ultra-faint dwarf spheroidal galaxies (UFDs). Because the metallicity and star formation history of Reticulum II appear consistent with all known UFDs, the high r-process abundance of Reticulum II suggests enrichment through a single, rare event, such as a double neutron star (NS) merger. However, we note that this scenario is extremely unlikely, as binary stellar evolution models require significant supernova natal kicks to produce NS-NS or NS-black hole mergers, and these kicks would efficiently remove compact binary systems from the weak gravitational potentials of UFDs. We examine alternative mechanisms for the production of r-process elements in UFDs, including a novel mechanism wherein NSs in regions of high dark matter density implode after accumulating a black-hole-forming mass of dark matter. We find that r-process proto-material ejection by tidal forces, when a single neutron star implodes into a black hole, can occur at a rate matching the r-process abundance of both Reticulum II and the Milky Way. Remarkably, dark matter models which collapse a single neutron star in observed UFDs also solve the missing pulsar problem in the Milky Way Galactic center. We propose tests specific to dark matter r-process production which may uncover, or rule out, this model.

description: No-go theorems assert that hidden-variable theories, subject to appropriate hypotheses, cannot reproduce the predictions of quantum theory. We examine two species of such theorems, value no-go theorems and expectation no-go theorems. The former assert that hidden-variables cannot match the predictions of quantum theory about the possible values resulting from measurements; the latter assert that hidden-variables cannot match the predictions of quantum theory about the expectation values of measurements. We sharpen the known results of both species, which allows us to clarify the similarities and differences between the two species. We also repair some flaws in existing definitions and proofs.

description: This Record documents the efforts of Geoscience Australia (GA) in compiling a New South Wales (NSW) Uranium–Lead (U–Pb) geochronology interpreted age compilation (version 1.0), utilising the MinView data from the Geological Survey of New South Wales (GSNSW), GA’s ‘in house’ storage of SHRIMP (Sensitive High Resolution Ion Micro Probe) ages, and other disparate publication sources e.g. academic journal articles and university theses. Here we describe both the dataset itself and the process by which it is incorporated into the continental-scale Isotopic Atlas of Australia. This initial release of the NSW geochronology compilation comprises of 1007 U–Pb ages of named and unnamed rock units in NSW. 
The Isotopic Atlas draws together age and isotopic data from across the country and provides visualisations and tools to enable non-experts to extract maximum value from these datasets. Data is added to the Isotopic Atlas in a staged approach with priorities determined by GA- and partner-driven focus regions and research questions. This NSW U–Pb compilation represents the third in a series of compilation publications (Records and Datasets) for the southern states of Australia, which are a foundation for the second phase of the Exploring for the Future initiative over the period 2020–2024. All geochronology compilations in this series of Isotopic Atlas of Australia Records are available online from the Geochronology and Isotopes Data Portal.

description: In this work it is introduced an extension of the study of the first law of thermodynamics of black holes based on the geometry of the extended phase space for AdS Lovelock gravities which includes changes of scales. As expected, the result obtained coincides with the previously known four dimensional case. For higher dimensions, the result is the arise of two new contributions to the first law of thermodynamics. The first term corresponds to corrections of the usual definition of thermodynamics volume at the horizon, due to the presence of the higher curvature terms. The second term arises in odd dimensions, comes from the asymptotic region, and corresponds to a scale transformation of the form $\propto \hatδ \ln (l/\ell)$, with $l$ the AdS radius and $\ell$ a parameter. A particularly interesting case corresponds to the Chern Simons gravity where the change scale does not generate a contribution at the asymptotic region, likely due to the Chern Simons AdS local symmetry.
"Maximum of wilderness"
Creators: name: Enright, Kelly
Publisher: name: No Publisher Supplied
Year: 2009

description: Many scholars have argued that the idea of wilderness was a driving force in the formation of American identity. Environmental historians have outlined how the definition of “wilderness” has changed throughout the nation’s history, but few scholars have considered the role of non-American landscapes in shifting notions of “the wild.” As both “unspoiled” and “unconquerable,” tropical forests have long figured into the American imagination. “Maximum of Wilderness,” a phrase film-makers Martin and Osa Johnson use to describe Borneo’s Rain Forest, traces the representation of tropical landscapes (along with their animal and human inhabitants) seeking to understand their place in both the history of the idea of nature and the globalization of the environmental movement.As a cultural construction, “the Jungle” is a dynamic mixture of myth and reality. At the beginning of the twentieth century, the Jungle was a popular theme in American culture; books and films such as Edgar Rice Burrough’s Tarzan (1914) and Merian C. Cooper’s King Kong (1933) created an image of adventure in tropical forests with mass appeal. While the popular image of the Jungle masked many of the real experiences in it, American naturalists sought to represent an “authentic” view of tropical nature in museums, zoological and botanical gardens, literature, and film. Through the lives and works of naturalists William Beebe, Martin and Osa Johnson, David Fairchild, and Richard Evans Schultes my work examines the relationship between popular and scientific representations of tropical nature—and the resonance of these images. My central concern is how and why this imagery shifts at mid-century from the Jungle as a place that endangered human lives to the Rain Forest, a place itself endangered. Still present in the American imagination, both images speak to the central place of tropical forests within constructions of adventure and wilderness, as well as to the American role in, and responsibility for, these landscapes.

Il cinema come campo di battaglia. Cineaste iraniane, la guerra con l’Iraq e la crisi in Afghanistan
Creators: name: Vanzan, Anna
Publisher: name: Storia delle Donne
Year: 2015

description: Globally speaking, War Cinema is predominantly a male construction. Though Iranian cinema makes no exception, in this rich cinematic production some women directors have been trying to build a gender constructed narrative of war. The article explores how women artists are using external conflicts problematically, as a metaphor for the internal war Iranian women have been fighting in the last decades.

Nocardia at UNC Hospitals, 2007 – 2016: An Analysis of Mortality According to Antibiotic Treatment
Creators: name: Saunders, Eleanor
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Objectives: To examine the epidemiology of all laboratory cases of Nocardiosis and to compare one-year mortality after treatment with first-line trimethoprim/sulfamethoxazole (TMP/SMX) for more than 2 weeks with treatment using other antibiotics (with a <2 week trial of TMP/SMX). Methods: We retrospectively analyzed treatments and outcomes of all adult patients with a first clinical sample positive for Nocardia tested at UNC Hospitals McLendon Clinical Laboratories in Chapel Hill, North Carolina between January 2007 and December 2016 (N=112). We used Fisher’s exact test to compare clinical and diagnostic characteristics of samples. We compared one-year all-cause mortality between two antibiotic treatment groups using a log-rank test. Results: One-year mortality was 2.6% greater (95 % CI -22.4 – 27.6) in the ≥2 weeks TMP/SMX group (7/31) than in the <2 weeks TMP/SMX group (3/15), a statistically insignificant difference. The log-rank test of one-year mortality between these groups produced an insignificant p-value of 0.7208. Conclusions. Treatment with TMP/SMX, though the gold standard, does not produce a statistically significant improvement in one-year all-cause mortality and causes substantial toxicity to a subset of patients. This warrants further study in which results could be pooled from multiple centers for a non-inferiority trial of alternative antibiotic regimens (e.g. imipenem or amikacin).
Dynamical phase coexistence in the Fredrickson-Andersen model

description: We analyse a first-order dynamical phase transition that takes place in the Fredrickson--Andersen (FA) model. We construct a two-dimensional spin system whose thermodynamic properties reproduce the dynamical large deviations of the FA model and we analyse this system numerically, comparing our results with finite-size scaling theory. This allows us to rationalise recent results for the FA model, including the exponential divergence of its susceptibility at phase coexistence. We also discuss a simple interfacial model that reproduces quantitatively the behaviour of the FA model at coexistence.

Carmen Barrenechea, la conciencia feminista de una matrona del siglo XIX en “La ciudad de la muerte”
Creators: name: Ruiz-Berdún, Dolores
Publisher: name: Storia delle Donne
Year: 2015

description: Many scholarly articles have been devoted to the study of the professional exclusion of European midwives at a time when male interest in obstetrics started to grow. There are, however, few references to the strategies adopted by midwives to defend the practice of their profession. In 1899, a midwife named Carmen Barrenechea published a request-like pamphlet, addressed to the major of the capital of Spain, in which she denounced the professional exclusion Spanish midwives were going through and vindicated the advantages of employing such professionals rather than surgeons.

Breastfeeding Friendly Child Care Designation Centers in New Hanover County: An Evaluation and Monitoring Proposal
Creators: name: Andersen, Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The Breastfeeding Friendly Child Care Designation (BFCCD) is associated with the more established Baby-Friendly Hospital Initiative, and both offer specific breastfeeding guidance and support to the breastfeeding mother and child. New Hanover County, in Southeastern North Carolina, currently has two BFCCD centers. This paper will establish the importance of the BFCCD program and propose a plan to evaluate and monitor the program’s key processes and the county’s resources available to child care centers. A Logic Model maps the proposed process in New Hanover County from resources available to specific public health goals. The level of designation is based on Ten Steps to Breastfeeding Friendly Child Care. Evaluating these steps will help determine the feasibility of different child care center’s ability to complete one or more of them, thereby increasing their level of designation, and monitoring will ensure the standards in achieving them are upheld and renewed. Disparities that exist in breastfeeding are also evident in BFCCD and will be addressed. The health benefits of breastfeeding for both mother and child have been scientifically proven beyond dispute for decades. Evaluating the BFCCD program in New Hanover County is a positive step toward expansion countywide and statewide and ultimately making a population level public health impact.

description: We evaluate the steady-state distribution and escape rate for an Active Ornstein-Uhlenbeck Particle (AOUP) using methods from the theory of large deviations. The calculation is carried out both for small and large memory times of the active force in one-dimension. We compare our results to those obtained in the literature about colored noise processes, and we emphasize their relevance for the field of active matter. In particular, we stress that contrary to equilibrium particles, the invariant measure of such an active particle is a non-local function of the potential. This fact has many interesting consequences, which we illustrate through two phenomena. First, active particles in the presence of an asymmetric barrier tend to accumulate on one side of the potential -a ratchet effect that was missing is previous treatments. Second, an active particle can escape over a deep metastable state without spending any time at its bottom.

description: We investigate the influence of the photon statistics on the excitation dynamics of a single two level system. A single semiconductor quantum dot represents the two level system and is resonantly excited either with coherent laser light, or excited with chaotic light, with photon statistics corresponding to that of thermal radiation. Experimentally, we observe a reduced absorption cross-section under chaotic excitation in the steady-state. In the transient regime, the Rabi oscillations observable under coherent excitation disappear under chaotic excitation. Likewise, in the emission spectrum the well-known Mollow triplet, which we observe under coherent drive, disappears under chaotic excitation. Our observations are fully consistent with theoretical predictions based on the semi-classical Bloch equation approach.

Ergonomic Issues in a Non-Primate Small Animal Facility in a Laboratory Setting

Year: 2004

description: Workers who handle small animals in a research laboratory are exposed to many risk factors which, if not addressed, can lead to work related musculoskeletal disorders (WMSDs ). Little data have been published that address the awkward postures, force, and repetition to which these workers are constantly exposed while providing care to maintain healthy animal colonies. This paper outlines a program for identifying and correcting ergonomic deficiencies and instituting prevention strategies. A guideline is provided for developing an interdisciplinary ergonomics team with occupational and environmental health nurses taking the lead, and the roles of other members of this team identified. A successful ergonomics program will lead to fewer work related musculoskeletal disorders and a healthier work force.
Exact minimax risk for linear least squares, and the lower tail of sample covariance matrices

description: We consider random-design linear prediction and related questions on the lower tail of random matrices. It is known that, under boundedness constraints, the minimax risk is of order $d/n$ in dimension $d$ with $n$ samples. Here, we study the minimax expected excess risk over the full linear class, depending on the distribution of covariates. First, the least squares estimator is exactly minimax optimal in the well-specified case, for every distribution of covariates. We express the minimax risk in terms of the distribution of statistical leverage scores of individual samples, and deduce a minimax lower bound of $d/(n-d+1)$ for any covariate distribution, nearly matching the risk for Gaussian design. We then obtain sharp nonasymptotic upper bounds for covariates that satisfy a "small ball"-type regularity condition in both well-specified and misspecified cases. Our main technical contribution is the study of the lower tail of the smallest singular value of empirical covariance matrices at small values. We establish a lower bound on this lower tail, valid for any distribution in dimension $d \geq 2$, together with a matching upper bound under a necessary regularity condition. Our proof relies on the PAC-Bayes technique for controlling empirical processes, and extends an analysis of Oliveira devoted to a different part of the lower tail.
