description: The Kramers-Kronig relations are a pivotal foundation of linear optics and atomic physics, embedding a physical connection between the real and imaginary components of any causal response function. A mathematically equivalent, but simpler, approach instead utilises the Hilbert transform. In a previous study, the Hilbert transform was applied to absorption spectra in order to infer the sole refractive index of an atomic medium in the absence of an external magnetic field. The presence of a magnetic field causes the medium to become birefringent and dichroic, and therefore it is instead characterised by two refractive indices. In this study, we apply the same Hilbert transform technique to independently measure both refractive indices of a birefringent atomic medium, leading to an indirect measurement of atomic magneto-optical rotation. Key to this measurement is the insight that inputting specific light polarisations into an atomic medium induces absorption associated with only one of the refractive indices. We show this is true in two configurations, commonly referred to in literature as the Faraday and Voigt geometries, which differ by the magnetic field orientation with respect to the light wavevector. For both cases, we measure the two refractive indices independently for a Rb thermal vapour in a 0.6 T magnetic field, finding excellent agreement with theory. This study further emphasises the application of the Hilbert transform to the field of quantum and atomic optics in the linear regime.

description: There has been a growing interest in non-Hermitian physics. One of its main goals is to engineer dissipation and to explore ensuing functionality. In magnonics, the effect of dissipation due to local damping on magnon transport has been explored. However, the effects of non-local damping on the magnonic analog of the Josephson effect remain missing, despite that non-local damping is inevitable and has been playing a central role in magnonics. Here, we uncover theoretically that a surprisingly rich dynamics can emerge in magnetic junctions due to intrinsic non-local damping, using analytical and numerical methods. In particular, under microwave pumping, we show that coherent spin precession in the right and left insulating ferromagnet (FM) of the junction becomes synchronized by non-local damping and thereby a magnonic analog of the $φ$ Josephson junction emerges, where $φ$ stands here for the relative precession phase of right and left FM in the stationary limit. Remarkably, $φ$ decreases monotonically from $ π$ to $π/2$ as the magnon-magnon interaction, arising from spin anisotropies, increases. Moreover, we also find a magnonic diode effect giving rise to rectification of magnon currents. Our predictions are readily testable with current device and measurement technologies at room temperatures.

A Formative Evaluation of Hire Hope: A Program Providing Career Opportunities for Victims of Sex Trafficking and Those At-Risk
Creators: name: Koncul, Jennifer
Publisher: name: Georgia State University
Year: 2015

description: BACKGROUND:
Human trafficking in all forms is an enormous violation of the most basic of human rights and a serious public health issue. This violation has been highlighted as a public health issue because of the severe mental and physical health consequences its victims face. Exact numbers do not currently exist, however, there are reports estimating the prevalence of this crime. It is estimated that 14,500-17,500 human trafficking victims are brought into the United States every year, with 70% of these victims being sold into the sex industry. Additionally, an estimated 300,000 minors in the United States are at-risk. Applying a public health perspective can provide a valuable framework for identifying risk factors, conducting research for new interventions, evaluating existing programs, and disseminating promising and best practices
PURPOSE:
This paper presents findings from a formative evaluation performed for Hire Hope. Hire Hope is a career-readiness and job placement program designed to meet the needs of young women who have become victims of sex trafficking and those who are at-risk of becoming victims. A review of the literature indicates that there is a need for evidence-based programs with proven effectiveness in aiding the rehabilitation of victims back into society, as well as interventions to prevent others from becoming victims. Hire Hope assists the participants’ reintegration into society by delivering a program that addresses known risk factors for sex trafficking: poverty and a lack of work opportunities.
METHODS:
Using a survey instrument administered through Qualtrics, data were collected to assess participant experiences with and reactions to the program. The survey measured five domains reflective of the program: Career Readiness, Self-Efficacy, Self-Awareness, Increased Knowledge, and Job & Apprenticeship Experience. Frequencies and percentages were calculated for statements answered on a 5-point Likert scale. Open-ended questions gathered qualitative data that were then analyzed for major themes. Observational data were gathered from observations of weekly training sessions.
CONCLUSIONS:
This evaluation of Hire Hope was conducted to provide the program staff with information they could use to improve the program. The survey responses revealed that Hire Hope is making progress in helping the women achieve the three primary program goals. The program also appears to be implemented as planned. Recommendations for Hire Hope include continued surveillance of the program, improved communication between program staff and their non-profit partners and a need for continued structure in the classroom. The information obtained from this formative evaluation will contribute to the limited knowledge base of programs for domestic victims of human trafficking and add to the list of programs victims that provide job placement services.

description: We revisit the problem of adsorption of a single He-4 layer on graphene, focusing on the commensurate C1/3 crystalline phase, specifically on whether it may possess a nonzero superfluid response, and on the existence of superfluid phases, either (metastable) liquid or vacancy-doped crystalline. We make use of canonical Quantum Monte Carlo simulations at zero and finite temperature, based on a realistic microscopic model of the system. Our results confirm the absence of any superfluid response in the commensurate crystal, and that no thermodynamically stable uniform phase exists at lower coverage. No evidence of a possibly long-lived, metastable superfluid phase at C1/3 coverage is found. Altogether, the results of ground-state projection methods and finite-temperature simulations are entirely consistent.

Publisher: name: Georgia State University
Year: 2015

description: The Morrow Community Garden was established as part of the “Lifelong Communities” initiative through the city of Morrow, Georgia and the Atlanta Regional Commission in 2012. Since then, a club of gardeners has helped sustain the garden and expand its capacity from 14 garden beds to 32 and have provided neighborhood residents with an opportunity to grow their own produce and make donations to a local clinic. With only financial support from membership dues, unstable membership, and limited space the garden is in need of an action plan to help meet its goals. Food deserts are regions where residents have limited access to fresh, affordable produce. These areas are often characterized by high minority population and low-income. Community gardens can help alleviate the health risk burden felt by residents of food deserts. Through establishing a relation with the Morrow Community Garden Club members and identifying goals and available resources, an action plan was created to help aid the garden club in its efforts to stabilize membership, expand the garden, educate city residents and create a youth engagement program.
An Ecological Study of the Cholera Outbreak in Rural and Urban Areas of Haiti
Creators: name: Emilien, Catherine
Publisher: name: Georgia State University
Year: 2015

description: INTRODUCTION. Haiti has been subject too many disasters such as the earthquake in January 2010 and ten months later was the introduction of the cholera which as affected over 700,000 people and claimed the life of more than 8,000 other people. For this study, my objectives is to understand the dynamics of the distribution of the cholera cases, the distribution of the proportion of cases hospitalized and the distribution of the case fatality rate based on the location and the season from the period of 81 weeks from October 31st 2011 to May 20th 2013.
METHODS AND RESULTS. Weekly data were obtained from the Haitian Ministry of Public Health and Population (MSPP) website from October 31st, 2011 to May 20th 2013 in 140 locations in Haiti. Of the total cholera cases (n=122427) studied, 59.39% were hospitalized, and there were 864 deaths total caused by cholera. Although there were more cases of cholera in the urban areas (n=65046) compared to the rural areas (n=57381), of the cholera cases hospitalized, 31.75% resided in rural areas and 27.63% in urban areas. Furthermore, a higher percentage of total deaths and hospital deaths were recorded in the rural areas with 0.46% and 0.35% respectively. To evaluate the distribution of the cholera outcomes based on the location type (urban-rural) and season type (dry-rain) I used the Wilcoxon rank sum test as the data appeared not normally distributed.
CONCLUSION. My findings suggest that more interventions should be made available in the rural locations of Haiti and mostly during the rainy seasons as oppose to the urban locations and during the dry seasons due to the burden of the cholera on the Haitian population; where a much higher number of cholera cases were found in the rural areas and during the rainy seasons.

description: The S = 1/2 triangular lattice antiferromagnet (TLAF) is a paradigmatic example of frustrated quantum magnetism. An ongoing challenge involves understanding the influence of exchange anisotropy on the collective behavior within such systems. Using inelastic neutron scattering (INS) and advanced calculation techniques, we have studied the low and high-temperature spin dynamics of Ba2La2CoTe2O12 (BLCTO): a Co2+-based Jeff = 1/2 TLAF that exhibits 120° order below TN = 3.26 K. We determined the spin Hamiltonian by fitting the energy-resolved paramagnetic excitations measured at T > TN, revealing exceptionally strong easy-plane XXZ anisotropy. Below TN, the excitation spectrum exhibits a high energy continuum having a larger spectral weight than the single-magnon modes, suggesting a scenario characterized by a spinon confinement length that markedly exceeds the lattice spacing. We conjecture that this phenomenon arises from the proximity to a quantum melting point, even under strong easy-plane XXZ anisotropy. Finally, we highlight characteristic flat features in the excitation spectrum, which are connected to higher-order van Hove singularities in the magnon dispersion directly induced by easy-plane XXZ anisotropy. Our results provide a rare experimental insight into the nature of highly anisotropic S = 1/2 TLAFs between the Heisenberg and XY limits.

description: Terahertz-band (100 GHz-10 THz) communication is a promising radio technology envisioned to enable ultra-high data rate, reliable and low-latency wireless connectivity in next-generation wireless systems. However, the low transmission power of THz transmitters, the need for high gain directional antennas, and the complex interaction of THz radiation with common objects along the propagation path make crucial the understanding of the THz channel. In this paper, we conduct an extensive channel measurement campaign in an indoor setting (i.e., a conference room) through a channel sounder with 0.1 ns time resolution and 20 GHz bandwidth at 140 GHz. Particularly, the impact of different antenna directivities (and, thus, beam widths) on the channel characteristics is extensively studied. The experimentally obtained dataset is processed to develop the path loss model and, subsequently, derive key channel metrics such as the path loss exponent, delay spread, and K-factor. The results highlight the multi-faceted impact of the antenna gain on the channel and, by extension, the wireless system and, thus, show that an antenna-agnostic channel model cannot capture the propagation characteristics of the THz channel.

description: Be X-ray binaries (Be-XRBs) are one of the largest subclasses of high-mass X-ray binaries, comprised of a rapidly rotating Be star and neutron star companion in an eccentric orbit, intermittently accreting material from a decretion disk around the donor. Originating from binary stellar evolution, Be-XRBs are of significant interest to binary population synthesis (BPS) studies, encapsulating the physics of supernovae, common envelope, and mass transfer (MT). Using the state-of-the-art BPS code, POSYDON, which relies on pre-computed grids of detailed binary stellar evolution models, we investigate the Galactic Be-XRB population. POSYDON incorporates stellar rotation self-consistently during MT phases, enabling detailed examination of the rotational distribution of Be stars in multiple phases of evolution. Our fiducial BPS and Be-XRB model align well with the orbital properties of Galactic Be-XRBs, emphasizing the role of rotational constraints. Our modeling reveals a rapidly rotating population ($ω/ω_\mathrm{crit} \gtrsim 0.3$) of Be-XRB-like systems with a strong peak at intermediate rotation rates ($ω/ω_\mathrm{crit} \simeq 0.6$) in close alignment with observations. All Be-XRBs undergo a MT phase before the first compact object forms, with over half experiencing a second MT phase from a stripped helium companion (Case BB). Computing rotationally-limited MT efficiencies and applying them to our population, we derive a physically motivated MT efficiency distribution, finding that most Be-XRBs have undergone highly non-conservative MT ($\barβ_\mathrm{rot} \simeq 0.05$). Our study underscores the importance of detailed angular momentum modeling during MT in interpreting Be-XRB populations, emphasizing this population as a key probe for the stability and efficiency of MT in interacting binaries.

The Evaluation Plan for the Linkage to Care Peer Guide Training Program
Creators: name: Phillips, Kasarah
Publisher: name: Georgia State University
Year: 2015

description: The evaluation plan for the Linkage to Care Peer Guide Training (LTC) program proposes a mixed method evaluation based on the needs of the stakeholders involved. The LTC Program is a pilot HIV health education program conducted at Georgia State University to train individuals to become peer guides. Peer guides are persons who can serve as a bridge between professional healthcare workers and the clients they serve. In this program, peer guides are used to help link individuals who are HIV positive to care and help identify barriers to treatment. This evaluation plan follows the program evaluation framework put forth by the Centers for Disease Control and Prevention (CDC) and describes activities that align with the following six steps: stakeholder engagement; program description; focusing the evaluation design; gathering credible evidence; justifying conclusions; and using evaluation findings (CDC, 2011). Because this is a program evaluation proposal, the justifying conclusions and ensuring use of evaluation findings steps of the CDC’s guide to program evaluation were modified to include only recommendations for data collection and for using the evaluation findings. This evaluation plan can be used by program implementers to collect summative data on the LTC Program.
An Evaluation of the Costs and Health Benefits Associated with an Overseas Voluntary HIV Screening Program for Refugees Undergoing Ressettlement to the United States
Creators: name: Canady, Michelle
Publisher: name: Georgia State University
Year: 2015

description: Since 2010, HIV screening is no longer required as part of the overseas medical examination for U.S.-bound refugees.  Estimated HIV prevalence for U.S-bound refugees range from 0% to 9%, with an average of 2.2%.  Based on this data, many refugees may be at high risk for HIV and HIV-associated infections and sequelae when compared to the 0.4% to 0.9% prevalence range in the U.S. population.

This capstone is an economic analysis of costs associated with an overseas voluntary HIV screening and treatment program for refugees undergoing resettlement to the U.S. This study seeks to answer the following question:

Will HIV screening for refugees overseas be less expensive for the U.S. government than domestic screening and will early screening have positive public health outcomes?

The results of this study suggest that HIV screening for refugees overseas will be less expensive for the U.S. government than domestic screening and early screening will have a positive effect on public health outcomes for refugees and receiving communities.  Increasing the rates of overseas screening should increase the number of refugees screened and linked to care at least 3 months earlier.
Patient Centered Medical Home (PCMH) Patient Education Brochure Research Proposal
Creators: name: Jarvis, Michael
Publisher: name: Georgia State University
Year: 2015

description: INTRODUCTION: Clinics within the Grady Health System (GHS) have been recently recognized as Patient Centered Medical Homes (PCMH) by the National Committee for Quality Assurance (NCQA). This creates a new standard of care for GHS, its clinics, and the surrounding neighborhood; but, the standard of care and features of the PCMH may not be fully understood or appreciated by GHS patients. Like many other municipal hospitals, the patient population of GHS tends to be lower in literacy and numeracy skills, on average, than the national population. Thus, communicating important PCMH standards and features to the GHS patient population can be challenging. OBJECTIVE: The objective of this project is to design a patient education brochure tailored to the needs and values of Grady PCMH patients to help them understand and navigate the Grady PCMH. This research proposal aims to provide information on PCMH standard and features in an easily understood brochure to individuals, for distribution to the local communities and patients that GHS serves. The proposed research will evaluate at what level of literacy and numeracy patients might better comprehend the new PCMH standards and what format of communication materials will assist patients in better navigating the health system, health education, and ultimately improving their health. It is important for this patient education brochure to be sensitive to the needs and values of the populations that Grady serves to better inform and motivate their patients of the benefits of the PCMH.
APPROACH: The proposed research will collect quantitative and qualitative data from a convenience sample of approximately 100 GHS adult patients who present for care at GHS and who consent to participate in a face-to-face interview. Patients will view a proposed brochure and be asked questions about its format, acceptability, and ease of understanding. Validated measures of health-related literacy and numeracy will be collected. Analyses will focus on overall acceptance and understanding of the proposed PCMH brochure and the associations of literacy and numeracy with acceptance and understanding.
IMPLICATIONS FOR POLICY AND PRACTICE: It is important for a patient brochure describing the benefits of a PCMH to be understood by the patients who are the intended beneficiaries of a PCMH. Improved awareness of PCMH standards and features will presumably help to ultimately improve patient navigation of the PCMH and ultimately their health behaviors and outcomes.

Reducing Youth Violence: The Role of Afterschool Programs
Creators: name: Tanner, Cordero
Publisher: name: Georgia State University
Year: 2015

description: INTRODUCTION: Youth violence is a significant public health problem that exists in the United States. In 2014, about 13 youth in the United States were victims of homicide each and every day and an additional 1,642 youth needed medical care because of physical assault-related injuries. Guided by social cognitive theory, it is understood that to inform youth development and decision making, youth need to be placed in structures where they are able to avoid violent situations, learn to solve problems non-violently by enhancing their peer relationships, learn how to interpret behavioral cues, and improve their conflict resolution skills. One such promising prevention strategy possibility is ensuring broad access to after-school programs that include such a structure. The purpose and plan for this capstone is to review the problem of youth violence, examine associated factors, and articulate a theoretical basis for after-school programs as a prevention strategy. The end product will be a policy brief, informing policymakers of the potential after-school programs have to help reduce youth violence in the United States.
METHODS: The scholarly literature was used to gather data on the problem of youth violence and to review and identify prevention strategies to reduce the problem. The after-school setting was identified as viable to prevention efforts. The capstone identified effective after-school programs that focused on youth exposure to violence. These programs will be identified and summarized in this paper. The databases used in this literature review were EBSCO and PubMed. This capstone also used addition resources such as programs websites, strategic guides, and manuals that related to violence, youth development, after-school programs, and prevention.
DISCUSSION: While after-school programs are a viable option for reducing youth violence, barriers exists that limit access to these programs. A review of the literature shows that over eleven million children are without supervision between the hours of 3 and 6 PM. The major reason for this is that limited funding goes into after-school programs. While using the social-cognitive theory to address individual and relationships factors that youth violence is important, that only addresses a portion of the issue. The upstream environmental factors have to be addressed as well, in particularly policies that shape the communities in which youth live. After the literature review, it is understood that there is a need to reduce youth violence and after-school programs are a viable option. This paper identifies two recommendations 1) implementing policy interventions and 2) state-ran after-school systems.
Short Staffed: Assessing the Effects of Primary Care Physician Shortages and Policy Recommendation for Georgia
Creators: name: Ramseur, Kimberly
Publisher: name: Georgia State University
Year: 2016

description: By the year 2025, the United States is predicted to face a shortage of between 46,000 - 90,000 physicians. Of specific concern are primary care physicians. With the rising costs of education, earning potential for those in specialty care, and the lack of interest in rural communities, it is no surprise that many physicians are foregoing the primary care route. As a result, rural areas are suffering, many operating without a healthcare facility or provider nearby. Individuals that reside within these communities often have poor health outcomes and are of lower socioeconomic status. In Georgia, there are several counties that are without do not have access to sufficient healthcare services. Many rural Georgians are forced to travel to neighboring counties to receive care. This poses a serious public health concern for many residents, public health officials, and policymakers throughout the state. The Georgia legislature has attempted to enact legislation that would address the effects of the physician shortage crisis for rural Georgians. Georgia is not the only state dealing with this issue and in response to the crisis many states have sought to expand the scope of practice for nurse practitioners and physician assistants. By providing nurse practitioners and physician assistants with greater autonomy such as prescriptive authority or the ability to diagnose and treat without physician supervision, states are likely to see greater access to care for those in rural communities, where there is a greater likelihood of nurse practitioner and physician assistants being in service. This paper will assess the effects of physician shortages in Georgia and offer suggestions on how to alleviate some of the burdens associated with this problem.
Improving Volunteer Engagement: Results of a Staff Needs Assessment at a Community Based Organization

Publisher: name: Georgia State University
Year: 2016

description: Volunteerism is a necessary component of most successful nonprofit organizations.  Building a successful volunteer program requires understanding the benefits of volunteerism, how organizations can best serve their volunteers, and how to sustain an engaged volunteer base. The purpose of this needs assessment was to determine staff’s volunteer needs and to develop a plan to increase volunteer engagement and retention. A secondary data analysis of survey results collected of paid staff (n = 34) from a mid-size Community Based Organization was conducted to assess volunteer needs. The survey measured (1) the number of staff with active volunteers and volunteer needs; (2) how staff foresee making use of volunteers; and (3) ways to improve the volunteer program. The results suggested that staff perceived the volunteer program to be useful but desired greater access to volunteers. Recommendations for cost-effective solutions to increasing volunteer participation and engagement were made.

description: To fully leverage the capabilities of mobile manipulation robots, it is imperative that they are able to autonomously execute long-horizon tasks in large unexplored environments. While large language models (LLMs) have shown emergent reasoning skills on arbitrary tasks, existing work primarily concentrates on explored environments, typically focusing on either navigation or manipulation tasks in isolation. In this work, we propose MoMa-LLM, a novel approach that grounds language models within structured representations derived from open-vocabulary scene graphs, dynamically updated as the environment is explored. We tightly interleave these representations with an object-centric action space. Given object detections, the resulting approach is zero-shot, open-vocabulary, and readily extendable to a spectrum of mobile manipulation and household robotic tasks. We demonstrate the effectiveness of MoMa-LLM in a novel semantic interactive search task in large realistic indoor environments. In extensive experiments in both simulation and the real world, we show substantially improved search efficiency compared to conventional baselines and state-of-the-art approaches, as well as its applicability to more abstract tasks. We make the code publicly available at http://moma-llm.cs.uni-freiburg.de.

Publisher: name: Georgia State University
Year: 2016

description: Audiologists are essential health care providers that need ongoing training in order to accurately identify and manage newborns, infants, and children with hearing impairment.  In Georgia, although there is a large audiology workforce, many lack the proper knowledge and skills in providing audiological care for children.  In order to improve care and understating, this guide was developed to be an all-inclusive resource for audiologists who assist in monitoring hospital screening programs, conduct follow-up screening and diagnostic evaluations, as well as audiological habilitation for children identified with hearing impairment.  Additionally, information on mandated reporting of audiological results and resources post identification, hearing aids and intervention resources, has been included.  The intended use of this guide is to disseminate through Georgia’s Department of Public Health and Georgia Academy of Audiology through email, website posting, and community and professional meetings.
Research Proposal for Developing Best Practices for Promoting Timely Follow Up Care for Patients in Non-rural Settings Discharged from Inpatient Psychiatric Care with Comorbid Chemical Dependency
Creators: name: Brody, Ryan
Publisher: name: Georgia State University
Year: 2016

description: Increasing the rate of timely follow up care for individuals who have been recently discharged from inpatient psychiatric care has been a goal of the US health care system for some time. Attempts at improving this rate through strategies such as care management, Critical Time Intervention, and comprehensive discharge planning have modestly improved rates, but further improvement should be possible.
A review of previously conducted research in this field indicates the need for a more focused analysis of the determinants of successful follow-up care strategies. Viewing individuals who have been discharged from inpatient psychiatric care as a single population may be an erroneous way of approaching this issue. The population of individuals who have been recently discharged from inpatient psychiatric care is heterogeneous, and strategies for improving continuity of care may be improved by tailoring intervention strategies to the specific characteristics and needs of subgroups of individuals being discharged from inpatient care. As such, this proposed study will focus on a narrower group of patients: those recently discharged from an inpatient psychiatric facility with a co-occurring chemical dependency diagnosis who live in a non-rural setting.
This research proposal suggests a methodology by which to study the potentially complex interactions between patient characteristics and interventions. The intended population is adults who were hospitalized for acute psychiatric care and who have comorbid chemical dependencies. Utilization of Medicaid claims data used with information gathered from insurers and inpatient facilities can provide information about whether or not a Medicaid patient has received timely follow up care. Discharge and post-discharge interventions put into place can be determined through a survey of the facilities regarding discharge procedures. This data can be used to evaluate the comparative effectiveness of the interventions offered at the various settings of care.

description: In this paper we present the results of a blind survey for compact sources in 243 Galaxy clusters that were identified using the thermal Sunyaev-Zeldovich effect (tSZ). The survey was carried out at 90 GHz using MUSTANG2 on the Green Bank telescope and achieved a $5σ$ detection limit of 1 mJy in the center of each cluster. We detected 24 discrete sources. The majority (18) of these correspond to known radio sources, and of these, 5 show signs of significant variability, either with time or in spectral index. The remaining sources have no clear counterparts at other wavelengths. Searches for galaxy clusters via the tSZ effect strongly rely on observations at 90 GHz, and the sources found have the potential to bias mass estimates of clusters. We compare our results to the simulation Websky that can be used to estimate the source contamination in galaxy cluster catalogs. While the simulation showed a good match to our observations at the clusters' centers, it does not match our source distribution further out. Sources over 104" from a cluster's center bias the tSZ signal high, for some of our sources, by over 50%. When averaged over the whole cluster population the effect is smaller but still at a level of 1 to 2%. We also discovered that unlike previous measurements and simulations we see an enhancement of source counts in the outer regions of the clusters and fewer sources than expected in the centers of this tSZ selected sample.

description: A 70-year-old right-handed housewife suffered an acute loss of taste, an unpleasant change in the taste of foods and liquids, and a strong aversion to all kinds of food due to a small lacune in the right dorsomedial pontine tegmentum. Eating became so unpleasant that she lost 7 kg in three weeks. Olfaction and the sensibility of the tongue were spared. The right medial longitudinal fascicle, the central tegmental tract, or both, were injured by the tegmental lesion. A discrete right-sided lesion in the upper pontine tegmentum may cause a reversible syndrome consisting of bilateral hypogeusia which is more severe ipsilaterally.
Diet Technicians in Dialysis: A Rare Opportunity to Decrease Costs and Improve Quality of Care
Creators: name: Clark, Lauren

description: As healthcare costs continue to rise beyond sustainable levels, both payors and providers are seeking ways to reduce their costs without sacrificing quality. End-stage renal disease (ESRD) accounts for a significant portion of Medicare expenditures, despite efforts over the years to alter the reimbursement scheme to control costs. Providers must now find a way to deliver care that both meets CMS quality standards and doesn’t exceed reimbursement amounts. Time and resource constraints have lead to registered dietitians reporting difficulty with providing important medical nutrition therapy to patients. Hiring dietetic technicians may be a cost-effective way to help improve nutrition therapy within the scope of the Medicare Conditions for Coverage for ESRD.

description: KCNB1-associated encephalopathy is characterized by intellectual disability (ID), autism spectrum disorder and epilepsy. Specific treatments are still lacking. We describe a 12-year-old boy with severe ID and treatment-resistant seizures due to a pathogenic KCNB1 variant. His EEG showed a CSWS pattern. Aged 11, he started treatment with highly purified cannabidiol (CBD) and has been seizure free for 18 months, with significant EEG and social skills improvements. This suggests CBD may benefit CSWS, likely due to its anti-inflammatory properties. Some preclinical studies also indicate CBDs interact with voltage-gated channels, leading us to speculate its possible role for treating KCNB1 related encephalopathy.
Assessment of Disparities in Health Care Access and Health Outcome among Racial and Ethnic Minorities

description: Health disparities are defined by the U.S. department of Health and Human Services (HHS) as health differences that are closely correlated with social, economic, and environmental disadvantages. Health disparities are disproportionately present among racial and ethnic minorities as a result of disparities in income, unemployment, education, and housing and environment. HHS has outlined five goals to reduce health disparities: (1) Transform health care by reducing barriers to access to care; (2) Strengthen the nation’s Health and Human Services infrastructure and workforce through increased diversity in the health care workforce and culturally competent care; (3) advance the health, safety, and well being of the American people by creating environments that promote healthy behavior;  (4) Advance scientific knowledge and innovation through increased patient centered research in prevention, screening, diagnostic and treatment services; and (5) Increase the efficiency and accountability of HHS programs by better coordinating and integrating minority health programs(Health and Human Services, 2011).

            Four reports (CDC, Inequalities Report, The Kelly Report, AHRQ, Disparities ad quality report, and the Westside Health Collaborative Report (WHC)) were used to attain a better view of the health disparities. The concordance of each report to the HHS goals, as well as concordance between reports of the description of health disparities in racial and ethnic minorities was assessed.
            All four reports were largely similar in their conclusion that racial and ethnic minorities experience greater barriers to access to healthcare and have higher rates of negative health outcomes.  The four reports were also similar in their recommendations for each of the five HHS goals. Medicaid expansion, increased access to health services and health education, training community health workers, increased funding for minority serving institutions, and increased race specific research were among the recommendations. Next steps should focus largely on implementation of programs rather than research
A Systematic Review of the Efficacy of Environmental Decontamination and Personal Hygiene Practices in Reducing Methicillin Resistant Staphylococcus aureus Acquisition
Creators: name: Green, Rhe'a
Publisher: name: Georgia State University
Year: 2016

description: Background 
Staphylococcus aureus is the leading cause of hospital acquired infections. Methicillin Resistant Staphylococcus aureus (MRSA) is the second most common healthcare associated infection in the healthcare system. A bacterium resistant to the antibiotic drug, methicillin, MRSA can make treatment for serious chronic illnesses difficult, leading to morbidity and mortality. 
Objective
The primary purpose of this study is to provide a systematic review of all research articles pertaining to the effectiveness of personal hygiene and environmental decontamination in controlling the transmission of methicillin-resistant Staphylococcus aureus (MRSA). 
Methods 
Databases PubMed, Global Health, and Medline were searched for research articles relevant to reducing MRSA acquisition using personal hygiene practices or environmental decontamination procedure. The keywords MSRA, MDRO, decontamination, hygiene, prevention, and clean were used to assist in identifying these articles. Full text articles were assessed to ensure they met inclusion criteria. Data was collected from each article regarding study time, location, outcome of interest, statistical result, and study design. 
Results
Of the articles included in this systematic review, 9    of 10 reported a significant decrease in MRSA acquisition in a healthcare or correctional facility setting after implementation of improved personal hygiene practices or environmental decontamination. There is an increased need for compliance with appropriate hygiene practices in a healthcare setting by healthcare workers. Further research needs to be conducted on the cost effectiveness of decontamination processes and educational programs to encourage compliance with MRSA policies that are already set in place by hospitals worldwide.
The Development of an Employee Wellness Program Within a Mid-Sized Company

description: INTRODUCTION: With over 160 million Americans currently in the workforce, employee wellness programs have proven to be a viable method of reaching a large population with an objective of improving health outcomes. These programs can encourage the awareness of health-related issues including nutrition, physical activity, preventative health screening, and stress management, and they also can serve to improve employee morale and/or engagement. Moreover, they can often help to reduce healthcare costs to both the organization and the individual employees. 
AIM:  The purpose of this capstone was to design a framework for an employee wellness program that could be utilized within a mid-sized private logistics company with multiple locations across the United States.
METHODS: The program was developed using the Precede portion of the PRECEDE-PROCEED model as the guiding framework. An essential first step of the program development involved a synthesis of published evidence involving published reports, reviews, and evaluations of other previously implemented worksite wellness initiatives.
RESULTS: A worksite wellness plan was proposed for a midsize company that addresses incentive policies, environmental changes, and recommended health education and behavioral structures for enhanced health and wellness among a workforce of approximately 800 employees.
DISCUSSION: The Proceed model steps will ensure a comprehensive evaluation of the program’s immediate impacts and long-term outcomes over time. It is important that the short, medium, and long term goals of the program are identified so that an evaluation process can be implemented to see if these specific objectives are met through the initiatives implemented in the program.
