description: Case Diagnosis: We present a case of a patient with hip pain during pregnancy determined to be pigmented villonodular synovitis (PVNS).

Case Description: A 41-year-old woman presented with 9-months of persistent atraumatic left hip pain localized to the groin that had started in her second trimester of pregnancy. Five months after delivery at presentation to clinic, her symptoms had progressively worsened to require a cane for ambulation.

On exam, hip range of motion was limited: flexion to 90o, external rotation to 20o, and internal rotation to 10o. She had groin pain with internal and external rotation. She was neurovascularly intact without lymphadenopathy.

Radiographs showed significant erosion of the left femoral head and acetabulum with mild protrusio. "Apple core" erosions were visualized at the femoral neck. MRI showed extensive bone edema on both sides of the joint, with erosion of the femoral head and acetabulum. There was joint effusion, synovial hypertrophy, and excessive synovial tissue.

Differential diagnoses included PVNS, avascular necrosis, rapidly progressive osteoarthritis, inflammatory arthritis, septic arthritis, insufficiency fractures, synovial chondromatosis, and transient osteoporosis of the hip. A needle biopsy confirmed the diagnosis of PVNS. She was treated with synovectomy and total hip arthroplasty, and has remained pain free and without evidence of disease for the last 5 years.

Discussions: PVNS is a disorder characterized by synovial proliferation. There are only two previous case reports of patients who were diagnosed with PVNS during pregnancy, both of whom had monoarticular involvement of the knee.

Conclusions: Synovectomy is the mainstay of surgical treatment of PVNS. Although, in patients with extensive articular involvement, synovectomy and arthroplasty may be required. The current understanding is that cytokines have a trophic influence leading to growth of the tumor. Further studies are needed to establish a definitive connection between PVNS and pregnancy.

description: Objectives: We aimed to determine the variability in position of the pelvis for patients while receiving daily radiation treatments for pelvic malignancies.

Design: Therapeutic radiation targets lymph nodes that lie along the curvature of the sacrum. Any change in pelvic tilt could inadvertently move these targets in or out of the radiation field. This variability has clinical significance both to target cancerous lymph nodes and avoid healthy sacrum.

To better understand this variability, we observed trends in the change in the sacral slope. This measurement was chosen because it is an objective radiographic finding, there is no significant difference between men and women, and joint replacement does not appear to change this measurement.

Twenty subjects were identified from patients receiving whole pelvis radiation for at least four weeks. CT simulator images and lateral radiographs obtained as part of standard radiation care were reviewed.

We manually calculated this measurement with sloping lines drawn with computer graphics on the same single lateral view daily for the course of radiation per subject.

Results: Compared to the initial imaging, the average sacral slope variation across all 20 subjects was 2.27 degrees, with a standard deviation of 1.43, and average variation among patients ranged from 1.22-5.09 degrees. Variation in sacral slope across all 20 subjects from one treatment day to the next was 2.05 degrees, with a standard deviation of 1.47, and ranged from 0.97-3.21 degrees.

Conclusions: Despite the best efforts of the provider, there may be some variability in the daily pelvic position of the patient between fractions. This is clinically important because presacral lymph nodes are part of the radiation target volume and sacral fractures are a potential adverse effect of radiation treatment. Exercises for pelvic relaxation could be explored to potentially reduce this variability.

description: Negative entropy has been known in Casimir systems for some time. For example, it can occur between parallel metallic plates modeled by a realistic Drude permittivity. Less well known is that negative entropy can occur purely geometrically, say between a perfectly conducting sphere and a conducting plate. The latter effect is most pronounced in the dipole approximation, which is reliable when the size of the sphere is small compared to the separation between the sphere and the plate. Therefore, here we examine cases where negative entropy can occur between two electrically and magnetically polarizable nanoparticles or atoms, which need not be isotropic, and between such a small object and a conducting plate. Negative entropy can occur even between two perfectly conducting spheres, between two electrically polarizable nano-particles if there is sufficient anisotropy, between a perfectly conducting sphere and a Drude sphere,and between a sufficiently anisotropic electrically polarizable nano-particle and a transverse magnetic conducting plate.

description: Case Diagnosis: We present two cases of atraumatic gluteus medius tear.

Case Description: Patient 1 is a 58-year-old female with right gluteal and hip pain. On physical exam, there was focal tenderness in the right gluteal area with pain on external rotation of the right hip and an antalgic gait.

Patient 2 is an 82-year-old male status-post left gluteus medius repair with subsequent revision. Since the surgery, the patient continued to have episodic left hip pain and suffered multiple falls. Physical exam demonstrated limited left hip abduction and tenderness of the iliopsoas muscle.

Both patients exhibited a sedentary lifestyle and neither had fluoroquinolone or steroid exposure near the time of tear.

Differential diagnoses included avascular necrosis of the femoral head, greater trochanteric bursitis, gluteal nerve injury, iliotibial band syndrome, paralabral cyst, and gluteus medius tear. For each patient, an MRI confirmed the diagnosis of gluteus medius tendon tear.

Both were referred to physical therapy. Patient 1 experienced decreased pain and Patient 2 experienced decreased pain, increased strength and range of motion, and increased ambulation.

Discussions: Chronic gluteus medius tears may be seen more frequently in those with decreased flexibility or strength. Neither patient had medication risk factors for muscle tear, but both endorsed a sedentary lifestyle. These tears can be treated successfully nonoperatively or with surgery. Nonoperative management includes pain control and physical therapy to target the hip rotators. Conservative treatment may provide up to 90% of patients with pain relief. However, few studies have evaluated the best exercises for the management of gluteus medius tears. Exercise can improve patient function without the risks associated with surgery.

Conclusions: This case series suggests that atraumatic gluteus medius tendon tears may be effectively treated nonoperatively, especially for patients with a sedentary lifestyle. Further studies should be conducted to evaluate the role of nonoperative treatment.

description: Although many high-energy neutrinos detected by the IceCube telescope are believed to have an extraterrestrial origin, their astrophysical sources remain a mystery. Recently, an unprecedented discovery of a high-energy muon neutrino event coincident with a multiwavelength flare from a blazar, TXS~0506+056, shed some light on the origin of the neutrinos. It is usually believed that a blazar is produced by a relativistic jet launched from an accreting supermassive black hole (SMBH). Here we show that the high-energy neutrino event can be interpreted by the inelastic hadronuclear interactions between the accelerated cosmic-ray protons in the relativistic jet and the dense gas clouds in the vicinity of the SMBH. Such a scenario only requires a moderate proton power in the jet, which could be much smaller than that required in the conventional hadronic model which instead calls upon the photomeson process. Meanwhile, the flux of the multiwavelength flare from the optical to gamma-ray band can be well explained by invoking a second radiation zone in the jet at a larger distance to the SMBH.

description: Weyl metal is regarded as a platform toward interacting topological states of matter, where its topological structure gives rise to anomalous transport phenomena, referred to as chiral magnetic effect and "negative" magneto-resistivity, the origin of which is chiral anomaly. Recently, the negative magneto-resistivity has been observed with the signature of weak anti-localization at $x = 3 \sim 4 ~ \%$ in Bi$_{1-x}$Sb$_{x}$, where magnetic field is applied in parallel with electric field. Based on the Boltzmann-equation approach, we find the negative magneto-resistivity in the presence of weak anti-localization. An essential ingredient is to introduce the topological structure of chiral anomaly into the Boltzmann-equation approach, resorting to semi-classical equations of motion with Berry curvature.

description: Analysis of 339 farmland sales in three areas of Oregon during 1965-69 showed that in each area, factors in addition to net rent income influenced prices paid. Corresponding property characteristics also varied in importance among areas in explaining differences in per acre prices paid. Values of six property characteristics were obtained for each sale—year of sale, acres in sale, building value per acre, miles to nearest paved road, miles to nearest town of at least 1,000 population, and landlord net real estate income per acre. Based on significant differences in the importance of property characteristics on prices paid and the apparent differences in motives for transactions among these areas, it was concluded that each area constituted a separate land market. Net rent-to-land price ratios varied from 4.3 percent in the dryland grain area to 2.8 percent in urban influenced Marion County to 1.0 percent in urban recreation influenced Douglas County. But because of the variability of rent-price ratios for individual properties within each area, a disparity between the farm use value and market price of farmland was concluded to exist only in Douglas County.

We find that the strength of the interaction between the different charge carriers, i.e., the inter-species interaction, plays a significant role in determining the number of plasmon modes as well as their dispersions in certain parameter regimes.

description: ACL2(ml) is an extension for the Emacs interface of ACL2. This tool uses machine-learning to help the ACL2 user during the proof-development. Namely, ACL2(ml) gives hints to the user in the form of families of similar theorems, and generates auxiliary lemmas automatically. In this paper, we present the two most recent extensions for ACL2(ml). First, ACL2(ml) can suggest now families of similar function definitions, in addition to the families of similar theorems. Second, the lemma generation tool implemented in ACL2(ml) has been improved with a method to generate preconditions using the guard mechanism of ACL2. The user of ACL2(ml) can also invoke directly the latter extension to obtain preconditions for his own conjectures.

description: Case Diagnosis: Post-irradiation Sarcoma. Case Description: A 58-year-old woman with a history of stage IIIB squamous cell carcinoma of the cervix who was treated with chemoradiation, considered in remission 5 years prior on PET CT, and was under every 6-months surveillance for recurrence by gynecology. She presented to the Emergency Department for severe back pain, left sided sciatica, and paresthesias. In the absence of fracture or cord compression, she was discharged with recommendations for primary care follow-up. This took place over the telephone with referral to the spine center. One week later, her pain progressed to 10+/10 with dense left leg numbness, and multiple falls. Physiatry ordered a lumbar MRI for focal neurologic findings on exam, which revealed a large destructive lesion of the left ilium and left hemisacrum with soft tissue extension. This was later determined to be undifferentiated sarcoma, likely due to prior radiation. She is currently undergoing palliative chemotherapy. Discussions: Post-irradiation sarcomas (PIS) are a relatively rare event and exhibit dose dependency. Sarcomas can present with bone pain that can be worse at night and signs and symptoms of compression of surrounding structures. The pelvis is a common site for sarcoma development. Cases of PIS have presented in even just a few months post radiation therapy. The prognosis of patients with PIS is poorer than those with primary sarcomas. This patient would require hemipelvectomy to attempt curative treatment. Conclusions: PIS are typically aggressive, have poor prognosis, and can develop within months of high doses of radiation therapies; clinicians index of suspicion for sarcomas in patients with a history of radiation must be high. Evaluation for progressive pain, weakness, and numbness may not be amenable to telemedicine until technology improves. Patients that present with signs and symptoms of progressive nerve compression and bone pain should be re-examined early on.

description: We propose two schemes to generate entanglement between a pair of mechanical oscillators using parametric amplification. In contrast to existing parametric drive-based protocols, both schemes operate in the steady-state. Using a detuned parametric drive to maintain equilibrium and to couple orthogonal quadratures, our approach can be viewed as a two-mode extension of previous proposals for parametric squeezing. We find that robust steady-state entanglement is possible for matched oscillators with well-controlled coupling. In addition, one of the proposed schemes is robust to differences in the damping rates of the two oscillators.

title: Point-of-contact interactive record linkage between demographic surveillance and health facilities to measure patterns of HIV service utilisation in Tanzania
Creators: name: Rentsch, CT
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2018

description: As significant investments and efforts have been made to strengthen HIV prevention and care service provisions throughout sub-Saharan Africa, approaches to monitoring uptake of these services have grown in importance. Global HIV/AIDS organisations use routinely updated estimates of the UNAIDS 90-90-90 targets, which state by 2020, 90% of all people living with HIV (PLHIV) should be diagnosed, 90% of diagnosed PLHIV should be receiving treatment, and 90% of PLHIV receiving treatment should achieve viral suppression. Currently, estimates of these targets in sub-Saharan Africa use population based demographic and HIV serological surveillance systems, which comprehensively measure vital events and HIV status but rely on self-reports of health service use. In contrast, most analyses of health service use are limited to patients already diagnosed and enrolled into clinical care and lack a population perspective. This thesis aims to augment existing computer software towards a novel approach to record linkage – termed point-of-contact interactive record linkage (PIRL) – and produce an infrastructure of linked surveillance data and medical records from clinics located within a surveillance area in northwest Tanzania. The linked data are then used to investigate methodological and substantive research questions. Paper A details the PIRL software that was used to collect the data for this thesis. Paper B reviews the data created by PIRL and reports record linkage statistics, including match percentages and attributes associated with (un)successful linkage. A subset of personal identifiers was found to drive the success of the probabilistic linkage algorithm, and PIRL was shown to outperform a fully automated linkage approach. Paper C provides original evidence measuring bias and precision in analyses of linked data with substantial linkage errors. Paper D critiques the estimation of the first 90-90-90 target and shows that current guidelines may underestimate the percentage diagnosed by a relative factor of between 10% and 20%. Finally, Paper E determines that while HIV serological surveillance has increased testing coverage, PLHIV who were diagnosed for HIV in a facility-based clinic were statistically significantly more likely to register for HIV care than those diagnosed at village-level temporary clinics during a surveillance round. Once individuals were in care, there was no evidence of any further delays to treatment initiation by testing modality. The collective findings of this thesis demonstrate the feasibility of PIRL to link community and medical records and use the linked data to measure patterns of HIV service use in a population.

description: Case Diagnosis: 67 year-old man was found down with dysarthria, dysphagia, and right lower limb weakness. He was diagnosed with left anterior cerebral artery ischemic stroke, acute renal failure, atrial fibrillation, and deep venous thrombosis. He remained hospitalized for months as he did not have insurance for inpatient rehabilitation care and could not be safely discharged home. Case Description: During that time, he got physical therapy 5 times per week and then 2 times per week. While hospitalized, he was subsequently diagnosed with left upper lobe nodule from T2aN0M0 lung adenocarcinoma. Physical therapy was increased back to 5 times per week for at least two weeks prior to left upper lobectomy and mediastinal lymphadenectomy by video-assisted thorascopic surgery 2.5 months after admission. Hospital course was complicated by anticoagulation and postoperative hemothorax, which responded to evacuation. He was discharged to subacute care after rate negotiation and then home. Discussions: We present the case of a patient who got physical therapy five times weekly in the 14 days prior to thoracic surgery. Although it is well established that exercise improves aerobic parameters and outcomes, the typical outpatient insurance benefit is under 120 minutes or only twice per week. 150 minutes a week is the current recommended amount of exercise for cancer patients. Since this patient could not be discharged due to lack of insurance for acute rehabilitation or outpatient care, he remained inpatient and received physical therapy five times weekly prior to surgery. Despite risk factors, he was safely discharged and recovered well. Conclusions: Our patient got a greater frequency and higher dose of exercise than most presurgical thoracic patients; this may be why he was able to tolerate thoracic surgery with multiple serious risk factors.

description: The coupling of geometrical and electronic properties is a promising venue to engineer conduction properties in graphene. Confinement added to strain allows for interplay of different transport mechanisms with potential device applications. To investigate strain signatures on transport in confined geometries, we focus on graphene nanoribbons (GNR) with circularly symmetric deformations. In particular, we study GNR with an inhomogeneous, out of plane Gaussian deformation, connected to reservoirs. We observe an enhancement of the density of states in the deformed region, accompanied with a decrease in the conductance, signaling the presence of confined states. The local density of states exhibits a six-fold symmetric structure with an oscillating sub-lattice occupation asymmetry, that persist for a wide range of energy and model parameters.

description: The TeV energy region is currently being explored by both the ATLAS and CMS experiments of the Large Hadron Collider and phenomena beyond the Standard Model are extensively searched for. Large fractions of the parameter space of many models have already been excluded, and the ranges covered by the searches will certainly be increased by the upcoming energy and luminosity upgrades. If new physics has to be discovered in the forthcoming years, the ultimate goal of the high-energy physics program will consist of fully characterizing the newly-discovered degrees of freedom in terms of properties such as their masses, spins and couplings. The scope of this paper is to show how the availability of polarized beams at high-energy proton-proton colliders could yield a unique discriminating power between different beyond the Standard Model scenarios. We first discuss in a model-independent way how this discriminating power arises from the differences between polarized and unpolarized parton distribution functions. We then demonstrate how polarized beams allow one not only to disentangle different production mechanisms giving the same final-state signature, but also to obtain information on the parameters of the hypothetical new physics sector of the theory. This is illustrated in the case of a particular class of scenarios leading to monotop production. We consider three specific models that could produce a monotop signature in unpolarized proton collisions, and show how they could be distinguished by means of single- and double-spin asymmetries in polarized collisions. Our results are presented for both the Large Hadron Collider operating at a center-of-mass energy of 14 TeV and a recently proposed Future Circular Collider assumed to collide protons at a center-of-mass energy of 100 TeV.

description: Background: Childhood obesity is a major public health problem. Studies of patterns of child growth contributing to the development of obesity are scarce, particularly in infancy. Group based trajectory analyses among infants are a novel procedure that may help characterize subgroups of infants with similar longitudinal growth profiles.

Objective: To identify trajectories of weight for length growth during the first year of life.

Methods: Subjects were singleton infants and their mothers (N=90 mother-infant pairs) who participated in the Pregnancy and Postpartum Observational Dietary Study. Women completed assessments throughout their infant's first year of life and included sociodemographic characteristics and feeding behaviors. Infant weight for length measures from birth to 12 months were abstracted from pediatric office records. Weight for length percentiles were calculated according to the World Health Organization guidelines for infants. Group-based trajectory analysis was done to identify subgroups of infants with similar growth profiles.

Results: Infants were from mother’s with average of 28 years (SD=5.2), 70.0% White, 60.0% high-school educated and 63.2% had two or more children. Over half of mothers introduced solid foods to their infants by 6 months of age (63.2%) and about one third self-reported breast feeding at 12 months post-partum (31.9%). Three growth trajectories were identified: a low and stable growth group (38.3%), a rapid growth group (35.0%) and a moderate growth group (26.7%). Maternal and feeding variables were all similar across the three infant growth trajectory groups (p>0.05).

Conclusion: Trajectory models suggested three patterns of infant growth. If replicated, future studies can help identify and subsequently target modifiable risk factors associated with rapid infant growth trajectories.

description: Background: Among adolescents, sugar-sweetened beverages (SSBs) are the primary source of added dietary sugar and constitute 10-15% of their total caloric intake. A range of factors influence adolescent dietary behaviors and food choices. This study aimed to explore adolescents' attitudes and knowledge about SSBs, how they receive messages about SSBs, and motivations for SSB consumption.

Methods: We conducted 5 focus groups with youth aged 12-14 years that attend one of the eight Youth Connect programs in Worcester, MA in 2016-2017. Groups were sex-specific because of changes during adolescence and experiences with body image and health behaviors between the groups. A semi-structured guide was used to facilitate a discussion with adolescents' around SSBs. The audio recorded data were transcribed and all transcripts were double coded. The data were analyzed using thematic analysis.

Results: Discussions included 16 boys in three focus groups and 17 girls in two groups. Participants were 12-14 years old, 27% identified as Hispanic, 24% black and 33% white. One third speaks more than one language at home and the majority consume SSBs daily. Qualitative analysis led to the identification and classification of various subdimensions under the following analytic categories: Attitudes, Motivations, Knowledge, and SSB Messaging. Common themes that emerge under each category will be reported. Analyses are in progress.

Conclusions: This research will present a deeper understanding of factors that influence Worcester adolescents' beverage choices from their own perspective. The information can be used in public health messaging in Worcester around obesogenic behaviors such as excess caloric intake from SSBs.
A modified multiple-relaxation-time lattice Boltzmann model for convection-diffusion equation

description: A modified lattice Boltzmann model with multiple relaxation times (MRT) for the convection-diffusion equation (CDE) is proposed. By modifying the relaxation matrix, as well as choosing the corresponding equilibrium distribution function properly, the present model can recover the CDE with anisotropic diffusion coefficient with no deviation term even when the velocity vector varies generally with space or time through the Chapman-Enskog analysis. This model is firstly validated by simulating the diffusion of a Gaussian hill, which demonstrates it can handle the anisotropic diffusion problem correctly. Then it is adopted to calculate the longitudinal dispersion coefficient of the Taylor-Aris dispersion. Numerical results show that the present model can further reduce the numerical error under the condition of non-zero velocity vector, especially when the dimensionless relaxation time is relatively large.

description: Purpose: We sought to conduct a pilot investigation of the reliability and administration fidelity of a new play-based measure of social communication for infants and toddlers with an autism diagnosis.Method: Our team adapted an existing measure, the Early Communication Indicator (ECI), for use with young autistic children in clinical and research contexts. In this brief report, we detail our adaptation process including administration and scoring of the final adapted measure based on data from a two-phase pilot study with young autistic children (N = 17).Results: This adapted measure, the Early Communication Indicator–Autism (ECI-A), captured a range of scores for the ECI, Initiation of Joint Attention, and Directed Communication in pilot testing. Interrater reliability was moderate to strong across the scored behaviors. Finally, parents were able to administer the ECI-A with high fidelity with support from the research staff.Conclusions: This two-phase pilot study demonstrated promise for the ECI-A as a brief measure of social communication that can be administered by parents and reliably scored by trained staff with limited background in autism assessments. Validation of the ECI-A is presently underway.Supplemental Material S1. Early Communication Indicator–Autism: Initiating joint attention and directed communication coding.Nowell, S., Steinbrenner, J.

description: Objective: Despite efforts to enhance inclusion, underrepresentation of minorities in research has been documented. The primary aim of this review was to evaluate representation of racial/ethnic sub-group members in behavioral weight loss interventions conducted among adults in the United States. The secondary aims were to assess recruitment and study design approaches to include racial/ethnic groups and the extent of racial/ethnic sub-group analyses conducted in these studies.

Methods: PubMed, PsycInfo, and Medline were searched for behavioral weight loss intervention trials conducted in 2009-2015 using keywords: weight, loss, overweight, obese, intervention and trial.

Results: The majority of the 87 studies reviewed included a majority White sample. Across the included studies, 61% of participants were White, 18% were Black/African American, 9% were Latino/Hispanic, 2% were Asian and 1% were American Indians. An additional 7.8% were categorized as “other”. Nine of the 87 studies enrolled exclusively minority samples. More than half (59.8%) of the studies did not report an intention, approach or specific site/location to recruit a sample that was racially or ethnically diverse. Of the 54 studies that included more than one racial/ethnic group, 8 included sub-group analyses of weight loss outcomes by race/ethnicity.

Conclusions: Lack of adequate representation of racial and ethnic minority populations in behavioral trials limits the generalizability and potential public health impact of these interventions. Given persistent racial/ethnic disparities in obesity in the U.S., the high morbidity, mortality, and economic costs associated with obesity and obesity-related conditions among racial/ethnic minority groups, findings from this review emphasize the need to maximize representation of some underrepresented racial/ethnic groups in behavioral lifestyle weight loss trials.

description: Background: Latinos bear high burden of nutrition related cardiovascular disease (CVD) risk factors. Dysfunctional eating behaviors (emotional eating, uncontrolled eating and cognitive restraint of eating) may influence metabolic CVD risk factors but little is known about this relationship in Latinos.

Objective: To examine associations between dysfunctional eating behaviors and metabolic risk factors for CVD in Latinos.

Methods: Latino individuals were recruited from a community health center. Participants completed standardized interviews (i.e., demographics, Three Factor Eating Questionnaire-TFEQ-R18V2, Perceived Stress Scale-10) and anthropometric measurements. Data on diagnosis of type 2 diabetes, hypertension and hyperlipidemia were abstracted from medical records. Statistical analysis included multivariable logistic and Poisson regression models.

Results: A total of 578 participants (51% female, 67% Dominican), ages 21-84, were included in this analysis. Controlling for age, sex, education and perceived stress high emotional eating (hEE) was associated with greater odds of obesity (OR=2.25 (1.47, 3.24)) and diabetes (OR=1.80 (1.07, 3.01)). High uncontrolled eating (hUE) was associated with obesity (OR=2.16 (1.34, 3.47)) and high cognitive restraint (hCR) was associated with greater odds of obesity (OR=2.55 (1.64, 3.98)), diabetes (OR=2.39 (1.40, 4.04) and hyperlipidemia (OR=1.92 (1.17, 3.14)). Lastly, hEE, hUE and hCR were significantly associated increased odds of having a greater number of the metabolic CVD risk factors (IRR=1.39 (1.20, 1.59), IRR=1.21 (1.04, 1.42), IRR=1.45 (1.24, 1.69); respectively).

Conclusion: Interventions that target eating behaviors may facilitate reduction of metabolic CVD risk factors and health disparities in CVD among Latinos.

description: In this paper, the connection between the path integral representation of propagators in the coherent state basis with additional degrees of freedom \cite{rohwer} and the one without any such degrees of freedom \cite{sgfgs} is established. We further demonstrate that the path integral formalism developed in the noncommutative plane using the coherent state basis leads to a quantum mechanics involving a Chern-Simons term in momentum which is of noncommutative origin. The origin of this term from the Bopp-shift point of view is also investigated. A relativistic generalization of the action derived from the path integral framework is then proposed. Finally, we construct a map from the commutative quantum Hall system to a particle in a noncommutative plane moving in a magnetic field. The value of the noncommutative parameter from this map is then computed and is found to agree with previous results.

description: Background: Food insecurity has been consistently associated with CVD risk factors (i.e., obesity, type 2 diabetes, hypertension and hypercholesterolemia). Consumption of fruits and vegetables may reduce CVD risk factors among food insecure Latinos.

Objective: To examine the potential moderating effect of fruit and vegetable intake in the association between food insecurity and CVD risk factors in a sample of Latino men and women in the northeast U.S.

Methods: A representative community sample of Latino individuals was recruited from a community health center in Lawrence, MA. Food insecurity was measured with the 6-item USDA Household Food Security Scale. Fruit and vegetable intake, was measured with Block’s Fruit and Vegetable Screener. CVD risk factors examined included: obesity assessed by body mass index (BMI), and diagnoses of type 2 diabetes, hypertension and hyperlipidemia abstracted from electronic health records. Covariates considered included: age, gender, education and BMI (except in the obesity model). Statistical analyses included multivariable logistic regression testing for interaction between food insecurity and diet.

Results: Overall, 51% of the sample were women and most self-identified as Dominicans (73%). Thirty-one percent of the sample experienced food insecurity and 79% consumed less than 5 servings of fruits and vegetables per day. Twenty percent of food secure participants and 23% of food insecure individuals consumed 5 servings or more of fruits and vegetables per day (p=0.439). In adjusted models, food insecurity was positively associated with type 2 diabetes in individuals consuming less than 5 servings of fruits and vegetables per day (OR=1.79; 95% CI=1.11–2.89) but not in individuals consuming 5 servings or more of fruits and vegetables per day. Interaction analyses showed that these estimates were significantly different from each other (p=0.04).

Conclusion: Among those who were food insecure, low consumption of fruits and vegetables, was associated with type 2 diabetes in this Latino sample. Studies are needed to confirm our findings. Further, longitudinal studies are needed to understand a potential causal relationship. Interventions to increase availability of fruits and vegetables among food insecure Latinos may help alleviate diabetes disparities in this vulnerable group.

description: Healthy Kids & Families, the applied research project of the UMass Worcester Prevention Research Center, is testing the impact of a community health worker (CHW)-delivered intervention aimed at helping families overcome barriers to childhood obesity prevention. The intervention addresses social, environmental, and family issues that may pose as barriers to healthy choices. The intervention is compared to a comparison condition consisting of a CHW-delivered intervention aimed at helping families improve positive parenting skills. The intervention and comparison condition are identical in format, Both use multiple delivery modalities to maintain novelty and prevent attrition/burden. These include home visits, telephone contacts, print (literacy sensitive newsletters), social media (Facebook), and community events. Parents and children will complete scheduled assessments at baseline, 6-, 12-, 18- and 24-month follow-up. Study participants are 240 parent-child dyads recruited from nine elementary schools. Inclusion criteria include: adult and their K-6th grade children attending a participating school, have access to a telephone, speak English or Spanish, and plan to live in the neighborhood for at least two years. Exclusion criteria include medical condition or advice from a doctor that precludes the child from walking or eating fruits and vegetables. Healthy Kids & Families is being implemented in racial/ethnically diverse underserved communities in Worcester, Massachusetts. Funded by the US Centers for Disease Control and Prevention, it involves a partnership between UMass Worcester Prevention Research Center of UMass Medical School, the Worcester Public Schools, and Oak Hill Community Development Corporation.

description: We construct super-Yang-Mills theories on S4 x R, S4 x S1 and S4 x interval with the field content of maximal SYM, coupled to boundary degrees in the last case. These theories provide building blocks of the `5d uplifts' of gauge theories on S4, obtained by compactifying the 6d (2,0) theory. We pay special attention to the N=2* theory on S4. We also explain how to construct maximal SYM on S5 x R, and clarify when SYM theories can be put on S^n x R.

description: Introduction: Evidence-based healthy eating (HE) policies can increase opportunities to engage in a healthy diet. The adoption of evidence-based policies into practice is limited and no study reports the status of HE policies nationally. Community Health Improvement Plans (CHIPs) strategically address health priorities, steer evidence-based strategy selection and implementation, and require collaboration. Local health departments (LHDs) are often key stakeholders. We aimed to determine the proportion of LHDs with a CHIP having evidence-based HE policies.

Methods:A national probability survey of US LHDs serving populations of

Results: 44.1% (95%CI: 34.7-54.0%) of US LHDs with a CHIP reported at least one evidence-based HE policy. The proportion of specific HE policies ranged from 28.9% for school district nutrition/procurement/vending policies to 1.3% for sugar-sweetened beverage tax.

Conclusions: Increased implementation of evidence-based HE policy approaches are needed within communities.
