Telephone interpersonal counseling with women with breast cancer: symptom management and quality of life.

PURPOSE/OBJECTIVES
To examine the effectiveness of a telephone interpersonal counseling (TIP-C) intervention compared to a usual care attentional control for symptom management (depression and fatigue) and quality of life (positive and negative affect, stress) for women with breast cancer.


DESIGN
Experimental with repeated measures.


SETTING
Academic cancer center and urban, private oncology offices.


SAMPLE
48 women with breast cancer who were in their mid-50s, married, and employed at the time of the study.


METHODS
Women were assigned to either the six-week TIP-C or attentional usual care groups. Women were matched on stage and treatment. Data were collected at baseline, after the six interventions, and one month postintervention. Measures included the Center for Epidemiologic Studies Depression Scale, Positive and Negative Affect Schedule, Multidimensional Fatigue Inventory, and Index of Clinical Stress.


MAIN RESEARCH VARIABLES
Depression, positive and negative affect, fatigue, and stress.


FINDINGS
Women in the intervention group experienced decreases in depression, fatigue, and stress over time and increases in positive affect.


CONCLUSIONS
The preliminary results partially supported the effectiveness of TIP-C for symptom management and quality of life. The authors hypothesized that decreased depression, reduced negative affect, decreased stress, decreased fatigue, and increased positive affect over time would be the resulting psychosocial effects, given the theoretical underpinnings of the intervention.


IMPLICATIONS FOR NURSING
Nurses need to assess the quantity and quality of the social support network early in treatment; women with less social support need to be referred to counseling and support services. Because these women have limited participation in face-to-face interventions, they should be encouraged to participate in telephone or online support programs or in other programs or organizations (e.g., churches, social clubs) that would provide support.
Flyback Versus Forward Switching Power Supply Topologies For Unipolar Pulsed-Power Applications

We discuss and compare modified flyback and forward switching power converter topologies in applications needing repetitive high-voltage (HV) low duty-cycle rectangular unipolar pulses. The output filters of these two converter topologies are removed, and the needed low duty-cycle operation is used advantageously to generate several kilovolts of pulses using only low-voltage seriesless semiconductors. The two circuits proposed are based on step-up transformers with a constant flux reset clamp that uses the low duty cycle required to reduce the voltage stress on all semiconductor switches. Prototypes were assembled using < 1-kV semiconductor switches to obtain -5-kV output pulses with 5-mus pulsewidth and 10-kHz pulse frequency. Experimental results are presented and discussed. The forward topology was found to be a better choice to deliver HV low duty-cycle unipolar rectangular pulses, and it was tested in a plasma load.
Early Inflammatory Markers Are Independent Predictors of Cardiac Allograft Vasculopathy in Heart-Transplant Recipients

BACKGROUND
Identification of risk is essential to prevent cardiac allograft vasculopathy (CAV) and graft failure due to CAV (GFDCAV) in heart transplant patients, which account for 30% of all deaths. Early CAV detection involves invasive, risky, and expensive monitoring approaches. We determined whether prediction of CAV and GFDCAV improves by adding inflammatory markers to a previously validated atherothrombotic (AT) model.


METHODS AND FINDINGS
AT and inflammatory markers interleukin-6 (IL-6) and C-reactive protein (CRP) were measured in heart biopsies and sera of 172 patients followed prospectively for 8.9±5.0 years. Models were estimated for 5- and 10-year risk using (1) the first post-transplant biopsy only, or (2) all biopsies obtained within 3 months. Multivariate models were adjusted for other covariates and cross-validated by bootstrapping. After adding IL-6 and CRP to the AT models, we evaluated the significance of odds ratios (ORs) associated with the additional inflammatory variables and the degree of improvement in the area under the receiver operating characteristic curve (AUROC). When inflammatory markers were tested alone in prediction models, CRP (not IL-6) was a significant predictor of CAV and GFDCAV at 5 (CAV: p<0.0001; GFDCAV: p = 0.005) and 10 years (CAV: p<0.0001; GFDCAV: p = 0.003). Adding CRP (not IL-6) to the best AT models improved discriminatory power to identify patients destined to develop CAV (using 1st biopsy: p<0.001 and p = 0.001; using all 3-month biopsies: p<0.04 and p = 0.008 at 5- and 10-years, respectively) and GFDCAV (using 1st biopsy: 0.92 vs. 0.95 and 0.86 vs. 0.89; using all 3-month biopsies: 0.94 vs. 0.96 and 0.88 vs. 0.89 at 5- and 10-years, respectively), as indicated by an increase in AUROC.


CONCLUSIONS
Early inflammatory status, measured by a patient's CRP level (a non-invasive, safe and inexpensive test), independently predicts CAV and GFDCAV. Adding CRP to a previously established AT model improves its predictive power.
Two-dimensional sheet resistance model for polycrystalline graphene with overlapped grain boundaries

Abstract Overlapped grain boundaries (OGBs) are an important feature of two-dimensional (2D) materials that are electrically, mechanically, and thermally different from conventional grain boundaries (CGBs). The properties of an individual OGB have been explored in some microscopic studies, but the effects of OGBs on the macroscopic properties of 2D materials such as sheet resistance and mobility have rarely been investigated. Therefore, it is necessary to identify and formulate the influence of the OGBs on the macroscopic properties of 2D materials. In this study, we propose a 2D sheet resistance and mobility model for polycrystalline graphene that considers the effects of OGBs and intra-grain defects. The proposed model is supported by a simulation of the growth and sheet resistance of graphene grown by chemical vapor deposition (CVD). The electrical properties were investigated with respect to the average grain size, and a threshold grain size for mobility saturation was introduced, which can provide directions for the growth of high-quality 2D materials for commercial use. Moreover, the 2D characteristics reflected in the model can explain the variation in the sheet resistance and mobility of graphene grown under the same conditions. Since this model is applicable to general 2D materials, it will provide guidelines for the growth of various 2D materials.

A graph theoretic framework for preventing the wormhole attack in wireless ad hoc networks

Wireless ad hoc networks are envisioned to be randomly deployed in versatile and potentially hostile environments. Hence, providing secure and uninterrupted communication between the un-tethered network nodes becomes a critical problem. In this paper, we investigate the wormhole attack in wireless ad hoc networks, an attack that can disrupt vital network functions such as routing. In the wormhole attack, the adversary establishes a low-latency unidirectional or bi-directional link, such as a wired or long-range wireless link, between two points in the network that are not within communication range of each other. The attacker then records one or more messages at one end of the link, tunnels them via the link to the other end, and replays them into the network in a timely manner. The wormhole attack is easily implemented and particularly challenging to detect, since it does not require breach of the authenticity and confidentiality of communication, or the compromise of any host. We present a graph theoretic framework for modeling wormhole links and derive the necessary and sufficient conditions for detecting and defending against wormhole attacks. Based on our framework, we show that any candidate solution preventing wormholes should construct a communication graph that is a subgraph of the geometric graph defined by the radio range of the network nodes. Making use of our framework, we propose a cryptographic mechanism based on local broadcast keys in order to prevent wormholes. Our solution does not need time synchronization or time measurement, requires only a small fraction of the nodes to know their location, and is decentralized. Hence, it is suitable for networks with the most stringent constraints such as sensor networks. Finally, we believe our work is the first to provide an analytical evaluation in terms of probabilities of the extent to which a method prevents wormholes.
An effective exploration approach to simultaneous mapping and surface material-type identification of complex three-dimensional environments

This paper presents an integrated exploration approach for geometric mapping and surface material–type identification of complex three-dimensional (3D) environments using a six-degree-of-freedom industrial robot manipulator. Maps of the surface geometry with the surface material type identified are required for an autonomous robotic system to perform operations in steel bridge maintenance. The proposed approach utilizes information theory to enable multiobjective exploration while new 3D geometric and surface-type data are fused via probabilistic updates. It is verified that the integrated approach enables the robotic system to perform exploration and surface inspection in real-world environments.
A randomized pilot study of MOtiVation and Enhancement (MOVE) Training for negative symptoms in schizophrenia

INTRODUCTION
Among individuals with schizophrenia, those who have persistent and clinically significant negative symptoms (PNS) have the poorest functional outcomes and quality of life. The NIMH-MATRICS Consensus Statement indicated that these symptoms represent an unmet therapeutic need for large numbers of individuals with schizophrenia. No psychosocial treatment model addresses the entire constellation of PNS.


METHOD
51 patients with PNS were randomized into one of two groups for a period of 9 months: 1) MOtiVation and Enhancement (MOVE) or 2) treatment as usual. MOVE is a home based, manual-driven, multi-modal treatment that employs a number of cognitive and behavioral principles to address the broad range of factors contributing to PNS and their functional consequences. The components of MOVE include: Environmental supports to prompt initiation and persistence, in-vivo skills training to ameliorate deficits and encourage interaction, cognitive behavioral techniques to address self-defeating attitudes, in-vivo training in emotional processing to address affective blunting and problems in identifying emotions, and specific techniques to address the deficits in anticipatory pleasure. Patients were assessed at baseline and each 3 months with multiple measures of negative symptoms.


RESULTS
Repeated measures analyses of variance for mixed models indicated significant Group by Time effects for the Negative Symptom Assessment (NSA; p<.02) and the Clinical Assessment Interview for Negative Symptoms (CAINS; p<.04). Group differences were not significant until 9 months of treatment and were not significant for the Brief Negative Symptom Scale (BNSS).


CONCLUSION
Further investigation of a comprehensive treatment for PNS, such as MOVE, is warranted.
Advanced laser techniques for filler-induced complications.

BACKGROUND
The increasing use of injectable fillers has been increasing the occurrence of disfiguring anaerobic infection or granulomas. This study presents two types of laser-assisted evacuation of filler material and inflammatory and necrotic tissue that were used to treat disfiguring facial nodules after different types of gel fillers.


MATERIALS AND METHODS
Infectious lesions after hydrogels were drained using a lithium triborate laser at 532 nm, with subsequent removal of infected gel and pus (laser assisted evacuation). Granuloma after gels containing microparticles were treated using an 808-nm diode laser using intralesional laser technique. The latter melted and liquefied the organic and synthetic components of the granulomas, facilitating subsequent evacuation. Both lasers had an easily controllable thin laser beam, which enabled the physician to control tissue damage and minimize discomfort and pain.


RESULTS
All 20 patients experienced reduction or complete resolution, the latter increasing with repeated treatments.


CONCLUSION
Laser-assisted treatment offers a successful solution for patients who have been suffering from disfiguring nodules from injected fillers-often for many years. The procedure broadens the range of treatment options in cases of untoward reactions to fillers, in line with surgical removal but with lower morbidity and less cosmetic disfigurement.
Linear Road: A Stream Data Management Benchmark

This paper specifies the Linear Road Benchmark for Stream Data Management Systems (SDMS). Stream Data Management Systems process streaming data by executing continuous and historical queries while producing query re sults in real-time. This benchmark makes it possible to compare the performance characteristics of SDMS’ relative to each other and to alternative (e.g., Relational Database) systems. Linear Road has been endorsed as an SDMS benchmark by the developers of both the Aurora [1] (out of Brandeis University, Brown University and MIT) and STREAM [8] (out of Stanford University) stream systems. Linear Road simulates a toll system for the motor vehicle expressways of a large metropolitan area. The tolling system uses “variable tolling” [6, 11, 9]: an increasingly prevalent tolling technique that uses such dynamic factors as traffic congestion and accident proximity to calculate to ll charges. Linear Road specifies a variable tolling system for a fictional urban area including such features as accident detection and alerts, traffic congestion measurements , toll calculations and historical queries. After specifyin g the benchmark, we describe experimental results involving two implementations: one using a commercially available Relational Database and the other using Aurora. Our results show that a dedicated Stream Data Management System can outperform a Relational Database by at least a factor of 5 on streaming data applications. ∗ This material is based on work supported by the National Scie nce Foundation under Grant Nos.

Efficacy and safety of linagliptin/metformin single-pill combination as initial therapy in drug-naïve Asian patients with type 2 diabetes.

AIM
To assess efficacy/safety of initial linagliptin/metformin single-pill combination (SPC) therapies versus individual drug components over 24weeks in treatment-naïve Asian patients with type 2 diabetes mellitus and insufficient glycemic control.


METHODS
Patients (initial glycated hemoglobin [HbA1c] ⩾7.5% to <11.0% [58-97mmol/mol]; main group) were randomized to: linagliptin 5mg once daily (qd); metformin 500mg twice daily (bid); metformin 1000mg bid; linagliptin 2.5mg/metformin 500mg bid; or linagliptin 2.5mg/metformin 1000mg bid. Patients with severe hyperglycemia (HbA1c ⩾11.0% [97mmol/mol]) received linagliptin 2.5mg/metformin 1000mg bid or linagliptin 5mg qd (switched at week 12 from linagliptin to SPC if HbA1c >8.0% [64mmol/mol]). The main group primary endpoint was HbA1c change from baseline to week 24.


RESULTS
At week 24, adjusted mean change from baseline in HbA1c (main group, n=733) was: linagliptin 5mg qd, -1.3%; metformin 500mg bid, -1.6%; metformin 1000mg bid, -2.1%; linagliptin 2.5mg/metformin 500mg bid, -2.2%; linagliptin 2.5mg/metformin 1000mg bid, -2.3%. The first test of primary HbA1c analysis (linagliptin 2.5mg/metformin 1000mg bid vs. metformin 1000mg bid) was borderline non-significant; however, SPCs produced significantly greater reductions in HbA1c from baseline versus respective monotherapies in all but one pre-defined sensitivity analysis. In the severe hyperglycemia group (n=143), linagliptin 2.5mg/metformin 1000mg bid produced a superior HbA1c reduction (-4.7%) versus linagliptin 5mg qd (-3.5%) after 12weeks. Hypoglycemic adverse events were low across groups.


CONCLUSIONS
Initial linagliptin/metformin SPC significantly improved glycemic control in this population.

Analysis of Transmedia Storytelling in Pokémon GO

This study is part of a doctoral thesis on the topic of Hyperfiction: Past, Present and Future of Storytelling through Hypertext. It explores in depth the impact of transmedia storytelling and the role of hypertext in the realm of the currently popular social media phenomenon Pokémon GO. Storytelling is a powerful method to engage and unite people. Moreover, the technology progress adds a whole new angle to the method, with hypertext and cross-platform sharing that enhance the traditional storytelling so much that transmedia storytelling gives unlimited opportunities to affect the everyday life of people across the globe. This research aims at examining the transmedia storytelling approach in Pokémon GO, and explaining how that contributed to its establishment as a massive worldwide hit in less than a week. The social engagement is investigated in all major media platforms, including traditional and online media channels. Observation and content analyses are reported in this paper to form the conclusion that transmedia storytelling with the input of hypertext has a promising future as a method of establishing a productive and rewarding communication strategy. Keywords—Communication, hypertext, Pokémon GO, storytelling, transmedia.
CIDP diagnostic pitfalls and perception of treatment benefit.

OBJECTIVE
We aimed to explore the diagnosis and misdiagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP) and to identify pitfalls that erroneously lead to a misdiagnosis.


METHODS
A retrospective study of 59 consecutive patients referred with a diagnosis of CIDP was performed. Patients were classified as having or not having CIDP according to European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) criteria. Diagnostic and treatment data were compared in the 2 groups.


RESULTS
Forty-seven percent of patients referred with a diagnosis of CIDP failed to meet minimal CIDP diagnostic requirements. All misdiagnosed patients who satisfied EFNS/PNS clinical criteria would be considered atypical as defined by the EFNS/PNS. CSF cytoalbuminologic dissociation was present in 50% of those without CIDP, although protein elevations were generally mild. Nerve conduction studies in patients without CIDP were heterogeneous, but generally showed demyelinating features better explained by a process other than CIDP. Patients frequently reported improvements after being treated with immunotherapy, even if the CIDP diagnosis was incorrect.


CONCLUSIONS
CIDP misdiagnosis is common. Over-reliance on subjective patient-reported perception of treatment benefit, liberal electrophysiologic interpretation of demyelination, and placing an overstated importance on mild or moderate cytoalbuminologic dissociation are common diagnostic errors. Utilization of clear and objective indicators of treatment efficacy might improve our ability to make informed treatment decisions.

Community-dwelling female fallers have lower muscle density in their lower legs than non-fallers: evidence from the Saskatoon Canadian Multicentre Osteoporosis Study (CaMos) cohort.

OBJECTIVES
Our objectives were to determine whether peripheral quantitative computed tomography (pQCT)-derived lower leg muscle density and area, and basic functional mobility differ between community-dwelling older women who do and do not report recent falls.


DESIGN
Matched case-control comparison.


SETTING
Academic biomedical imaging laboratory.


PARTICIPANTS
147 Women, 60 years or older (mean age 74.3 y, SD 7.7) recruited from a longitudinal, population-based cohort representing community-dwelling residents in the area of Saskatoon, Canada.


MEASUREMENTS
A cross-sectional pQCT scan of the non-dominant lower leg was acquired to determine muscle density and area. Basic functional mobility (Timed Up and Go Test [TUG]) and SF36 health status were also measured. Fallers (one or more falls) and non-fallers (no falls) were grouped according to a 12-month retrospective survey and matched on measured covariates.


RESULTS
The muscle density of fallers (n = 35) was a median of 2.1 mg/cm3 lower (P = 0.019, 95% C.I. -3.9 to -0.1) than non-fallers (n = 78) after matching and adjusting for age, body mass index, and SF36 general health scores. Muscle area and TUG did not differ between fallers and non-fallers.


CONCLUSIONS
Muscle density may serve as a physiological marker in the assessment of lower leg muscular health and fall risk in community-dwelling elderly women. These results are limited to our study population who were mostly Caucasian. Prospective studies are required for verification.
