A Methodological Approach to Determine Flower Bud Vulnerability to Low Temperatures for Deciduous Crops in Early Spring Using Degree Days
Authors: Peña Quiñones Andrés Javier , Salazar Gutierrez Melba Ruth , Hoogenboom Gerrit
Published: March 2020

A common problem for decision makers in selecting frost control options is uncertainty about the level of injury that can be caused by low temperatures. During the past few years, the concept of lethal temperature (LT) at which 10% of the bud population dies (LT10) has been used as an index for evaluating the vulnerability of flower buds to low temperature conditions. This concept has shown to be a useful tool for frost control decision-making. However, the current methods used to obtain LT values assume no spatial or temporal variability, which results in a high level of uncertainty. The goal of this study was to develop an approach that decreases the uncertainty based on the known effects of temperature on bud vulnerability. A growth chamber experiment was conducted to determine flower bud vulnerability to low temperature as a function of temperature. The results from this study showed that thermal time expressed in degree days could explain changes in floral bud development and vulnerability to frost injury. According to our findings, LT10 is a fully acceptable index for determining flower bud vulnerability to low temperatures in orchard crops. Based on this information, we found that among the five apple and cherry cultivars analyzed, ‘Gala’ is the least vulnerable to low temperature because it starts at the beginning of spring with a high level of hardiness and increases its vulnerability at a low rate. The approach described in this article may enhance decision-making certainty associated with the timing and methods to increase air temperature in orchards during low-temperature events to avoid frost damage.
Systemic risk and interconnectedness in Gulf Cooperation Council banking systems
Authors: Nekhili Ramzi
Published: March 2020

Nowadays, financial interconnectedness is the main driver of systemic risk. Thus, there is a constant need for tools to assess and manage systemic risk. This paper offers an alternative model framework to measure systemic risk and examine interconnectedness between direct exposures across banking systems in the emerging markets of the Gulf Cooperation Council (GCC). To ensure consistency and efficiency of systemic risk estimates and to capture its multifaceted nature, the methodology measures systemic risk using a combination of Filtered Historical Simulation and nonparametric regression and then examines the interconnectedness using a network analysis. The results reveal that shocks originating in the banking systems in Saudi Arabia may potentially cause a cascade of failures in the banking systems of most GCC countries. The banking system in Oman, however, is robust enough to withstand any ripple effect from adverse shocks affecting GCC’s major banking systems. Such results present some policy implications for regulators and supervisors and may benefit asset managers and investors in making portfolio allocation decisions.

Authors: Perales Aguilar Lucila , Santos Díaz Ma. del Socorro , Gómez Aguirre Yenny Adriana , Ramos Gómez Magdalena Samantha , Perez Molphe Balch Eugenio
Published: March 2020

Introducción: La familia Asparagaceae incluye varios géneros adaptados para sobrevivir a altas temperaturas y con baja disponibilidad de agua. Entre éstos destacan Agave, Beaucarnea, Dasylirion, Nolina y Yucca. México cuenta con una gran biodiversidad de estos grupos vegetales, así como con una tradición ancestral en cuanto a su uso. Los sistemas de propagación in vitro son eficientes para la producción de estas plantas, y además pueden ser usados para llevar a cabo diversos tipos de estudios. Entre estos, están los estudios de tolerancia a metales pesados, los cuales pueden servir para determinar qué especies son aptas para la reforestación y regeneración de áreas contaminadas por actividades mineras.Método: En este trabajo se propagaron in vitro 20 especies de la familia Asparagaceae, y se evaluó su proceso de enraizamiento en medios de cultivo adicionados con Cd, Cu, Cr, Fe, Mn, Pb y Zn. Se analizó el desarrollo de las raíces en presencia de estos metales y se determinó su capacidad de absorberlos mediante espectrofotometría de absorción atómica de llama. Con estos datos se calcularon los factores de translocación y bioacumulación con el fin de caracterizar la respuesta de cada especie ante los metales pesados.Resultados: El mayor número de brotes se presentó en las especies Beaucarnea recurvata con 5.7 y Nolina durangensis con 5.6 brotes por explante, respectivamente. El tratamiento con cromo fue tóxico para la mayoría de las especies. Agave celsii, A. chiapensis, A. obscura, A. palmeri y A. salmiana formaron raíz en todos los tratamientos con metales. De acuerdo a los factores de translocación y bioacumulación las especies analizadas se clasificaron como fitoestabilizadoras, exclusoras, bioacumuladoras e indicadoras. Las especies A. chiapensis, A. obscura y A. palmeri fueron bioacumuladoras para Mn. A. celsii y A. salmiana presentaron mecanismos de fitoestabilización y exclusión.Conclusión: La propagación in vitro permite generar grandes cantidades de plantas y además estudiar sus respuestas ante la presencia de contaminantes. El género Agave mostró ser tolerante a los metales, por lo que se puede usar para fitoestabilizar y remediar suelos contaminados.

Published: March 2020

In this study the effect of pollen source (mesquite and catclaw) on the sensory characteristics (appearance, color, aroma, taste, consistency and visible impurities), and physicochemical properties of raw propolis, and the phenolic content and biological activities of propolis extracts (PEs) was determined. The phenolic composition of PEs was determined by the total phenolic (TPC), flavone and flavonol (FFC), and flavanone and dihydroflavonol content (FDC). The individual phenolic components were analyzed by HPLC-DAD. The antioxidant activity was determined by the ferric-reducing power (FRAP) and free-radical scavenging activity (FRS). The antibacterial activity was evaluated against Gram-positive (Staphylococcus aureus and Listeria innocua) and Gram-negative (Echerichia coli and Salmonella thyphimurium) bacteria. The results showed that sensory characteristic and physicochemical properties of mesquite and catclaw propolis complied with international quality regulations. Fifteen phenolic compounds were identified, of which pinocembrin, naringenin, galangin, chrysin and quercetin were found a high concentration (> 3 mg/g). Mesquite propolis had the highest phenolic content (TFC and FDC), as well as antioxidant activity (> 2.5 mg Fe (II) equivalent/g; > 40% of DPPH radical inhibition) and antibacterial activity against Gram-positive bacterias in the order S. aureus > L. innocua (> 50% of inhibition for both bacterias at 500 µg/mL). These results indicating that pollen source affect the sensory characteristics and physicochemical properties of propolis, as well as the biological activity of their extracts.

Authors: Torabi Seyed Alireza , Mastouri Reza , Najarchi Mohsen
Published: March 2020

Accurate estimating of daily streamflow forecasting is one of the prominent topics in water resources activities. In this paper, an integrated method including decomposition technique based on the ensemble empirical mode decomposition (EEMD) combined with multivariate adaptive regression spline (MARS) was carried out to predict daily streamflow values. Daily streamflow value datasets collected from two stations in Iran (Gachsar and Kordkheyl) were selected. After dividing into calibration and validation datasets, each of them was decomposed by EEMD. Crow search algorithm (CSA) was used to optimize the MARS parameters (MARS-CSA). The performance of the integrated model (EEMD-MARS-CSA) was investigated by error indices (correlation coefficient (R), root mean squared error (RMSE), mean absolute error (MAE), Nash–Sutcliffe efficiency (NSE), as well as RMSE to standard deviation ratio (RSR)). From the results, EEMD was an important tool for increasing model accuracy and EEMD-MARS-CSA outperformed other alternative methods for daily streamflow estimation. According to one-day-ahead flow forecasting, EEMD-MARS-CSA (R = 0.94, RMSE = 5.94 m3/s (Kordkheyl) and R = 0.98, RMSE = 0.71 m3/s (Gachsar)) outperformed EEMD-MT/MARS, MT, and MARS models. Furthermore, RSR criterion of EEMD-MARS-CSA was reduced by 18%, 16%, and 17% for 3-days, 1-week, and 2-weeks-ahead streamflow forecasting compared to MARS-CSA model, respectively, for Gachsar station.

JÜRGEN HABERMAS: o direto como linguagem
Authors: Mello Marcelo Pereira de
Published: March 2020

Este artigo tem como objetivo analisar a Sociologia do Direito de Jürgen Habermas, mostrando a centralidade do direito na sua teoria da ordem social. Como sociólogo formado na tradição alemã de grandes sínteses filosóficas, Habermas, em seu livro " Direito e Democracia – Entre facticidade e validade ", que nos guiará neste artigo, descreve o objetivo ambicioso de produzir uma teoria geral da ação social à maneira de Parsons. Em sua explicação sobre a natureza das sociedades, o direito positivo é entendido como uma linguagem estabilizadora das interações sociais tendo o importante papel de estruturar a ordem social. Celebrado entre os juristas, o entendimento completo das proposições de Habermas requer conhecimento amplo e crítico das teorias sociológicas sobre a natureza da ordem social. Muitas vezes secundarizado por sociólogos, especialmente os tradicionalistas e conservadores, o autor promove um entendimento das normas legais como um processo dialógico e multideterminado, que não é apenas um reflexo das relações sociais, mas que também estabelece parâmetros para a composição de conflitos inerentes às interações sociais.
The Blood-Brain Barrier Interface in Diabetes Mellitus: Dysfunctions, Mechanisms and Approaches to Treatment
Authors: Banks William A.
Published: March 2020

Diabetes mellitus (DM) is one of the most common diseases in the world. Among its effects are an increase in the risk of cognitive impairment, including Alzheimer’s disease, and blood-brain barrier (BBB) dysfunction. DM is characterized by high blood glucose levels that are caused by either lack of insulin (Type I) or resistance to the actions of insulin (Type II). The phenotypes of these two types are dramatically different, with Type I animals being thin, with low levels of leptin as well as insulin, whereas Type II animals are often obese with high levels of both leptin and insulin. The best characterized change in BBB dysfunction is that of disruption. The brain regions that are disrupted, however, vary between Type I vs Type II DM, suggesting that factors other than hyperglycemia, perhaps hormonal factors such as leptin and insulin, play a regionally diverse role in BBB vulnerability or protection. Some BBB transporters are also altered in DM, including P-glycoprotein, lowdensity lipoprotein receptor-related protein 1, and the insulin transporter as other functions of the BBB, such as brain endothelial cell (BEC) expression of matrix metalloproteinases (MMPs) and immune cell trafficking. Pericyte loss secondary to the increased oxidative stress of processing excess glucose through the Krebs cycle is one mechanism that has shown to result in BBB disruption. Vascular endothelial growth factor (VEGF) induced by advanced glycation endproducts can increase the production of matrix metalloproteinases, which in turn affects tight junction proteins, providing another mechanism for BBB disruption as well as effects on P-glycoprotein. Through the enhanced expression of the redox-related mitochondrial transporter ABCB10, redox-sensitive transcription factor NF-E2 related factor-2 (Nrf2) inhibits BEC-monocyte adhesion. Several potential therapies, in addition to those of restoring euglycemia, can prevent some aspects of BBB dysfunction. Carbonic anhydrase inhibition decreases glucose metabolism and so reduces oxidative stress, preserving pericytes and blocking or reversing BBB disruption. Statins or N-acetylcysteine can reverse the BBB opening in some models of DM, fibroblast growth factor-21 improves BBB permeability through an Nrf2-dependent pathway, and nifedipine or VEGF improves memory in DM models. In summary, DM alters various aspects of BBB function through a number of mechanisms. A variety of treatments based on those mechanisms, as well as restoration of euglycemia, may be able to restore BBB functions., including reversal of BBB disruption.
Design of Lamivudine Loaded Nanoparticles for Oral Application by Nano Spray Drying Method: A New Approach to use an Antiretroviral Drug for Lung Cancer Treatment
Authors: Öztürk Ahmet Alper , Namlı İrem , Güleç Kadri , Görgülü Şennur
Published: March 2020

Aims:

To prepare lamivudine (LAM)-loaded-nanoparticles (NPs) that can be used in lung cancer treatment. To change the antiviral indication of LAM to anticancer.

Background:

The development of anticancer drugs is a difficult process. One approach to accelerate the availability of drugs is to reclassify drugs approved for other conditions as anticancer. The most common route of administration of anticancer drugs is intravenous injection. Oral administration of anticancer drugs may considerably change current treatment modalities of chemotherapy and improve the life quality of cancer patients. There is also a potentially significant economic advantage.

Objective:

To characterize the LAM-loaded-NPs and examine the anticancer activity.

Methods:

LAM-loaded-NPs were prepared using Nano Spray-Dryer. Properties of NPs were elucidated by particle size (PS), polydispersity index (PDI), zeta potential (ZP), SEM, encapsulation efficiency (EE%), dissolution, release kinetics, DSC and FT-IR. Then, the anticancer activity of all NPs was examined.

Results:

The PS values of the LAM-loaded-NPs were between 373 and 486 nm. All NPs prepared have spherical structure and positive ZP. EE% was in a range of 61-79%. NPs showed prolonged release and the release kinetics fitted to the Weibull model. NPs structures were clarified by DSC and FT-IR analysis. The results showed that the properties of NPs were directly related to the drug:polymer ratio of feed solution. NPs have potential anticancer properties against A549 cell line at low concentrations and non-toxic to CCD 19-Lu cell line.

Conclusion:

NPs have potential anticancer properties against human lung adenocarcinoma cells and may induce cell death effectively and be a potent modality to treat this type of cancer. These experiments also indicate that our formulations are non-toxic to normal cells. It is clear that this study would bring a new perspective to cancer therapy.
Epigenetic Therapies and Potential Drugs for Treating Human Cancer
Authors: Lin Shi-qi , Li Xia
Published: March 2020

Epigenetic modifications ensure the maintenance of normal cellular functions, and their
dysregulation is frequently found in many disease states, including cancer. Nowadays, the most studied
epigenetic dysregulation associated with tumorigenesis, cancer progression and metastasis refers to
the variations in DNA methylation, histone modification and chromatin structure. The development of
novel agents targeting these processes has enabled us to open up new pathways for anti-cancer strategies.
To date, many small molecules have been designed to target epigenetic modifiers, and some of
them are currently in clinical trials for patients with haematologic malignancies and solid tumours.
With this in mind, we elaborate on basic information on epigenetic modifications and potential epigenetic
therapies for cancer treatment.

Published: March 2020

Background:

Emerging viral zoonotic diseases are one of the major obstacles to secure the “One Health” concept under the current scenario. Current prophylactic, diagnostic and therapeutic approaches often associated with certain limitations and thus proved to be insufficient for customizing rapid and efficient combating strategy against the highly transmissible pathogenic infectious agents leading to the disastrous socio-economic outcome. Moreover, most of the viral zoonoses originate from the wildlife and poor knowledge about the global virome database renders it difficult to predict future outbreaks. Thus, alternative management strategy in terms of improved prophylactic vaccines and their delivery systems; rapid and efficient diagnostics and effective targeted therapeutics are the need of the hour.

Methods:

Structured literature search has been performed with specific keywords in bibliographic databases for the accumulation of information regarding current nanomedicine interventions along with standard books for basic virology inputs.

Results:

Multi-arrayed applications of nanomedicine have proved to be an effective alternative in all the aspects regarding the prevention, diagnosis, and control of zoonotic viral diseases. The current review is focused to outline the applications of nanomaterials as anti-viral vaccines or vaccine/drug delivery systems, diagnostics and directly acting therapeutic agents in combating the important zoonotic viral diseases in the recent scenario along with their potential benefits, challenges and prospects to design successful control strategies.

Conclusions:

This review provides significant introspection towards the multi-arrayed applications of nanomedicine to combat several important zoonotic viral diseases.
Cardiovascular Complications of Sleep Disorders: A Better Night’s Sleep for a Healthier Heart / From Bench to Bedside
Authors: Manolis Theodora A. , Manolis Antonis A. , Apostolopoulos Evdoxia J. , Melita Helen , Manolis Antonis S.
Published: March 2020

Sleep is essential to and an integral part of life and when lacking or disrupted, a multitude of
mental and physical pathologies ensue, including cardiovascular (CV) disease, which increases health
care costs. Several prospective studies and meta-analyses show that insomnia, short (<7h) or long (>9h)
sleep and other sleep disorders are associated with an increased risk of hypertension, metabolic syndrome,
myocardial infarction, heart failure, arrhythmias, CV disease risk and/or mortality. The mechanisms
by which insomnia and other sleep disorders lead to increased CV risk may encompass inflammatory,
immunological, neuro-autonomic, endocrinological, genetic and microbiome perturbations. Guidelines
are emerging that recommend a target of >7 h of sleep for all adults >18 years for optimal CV
health. Treatment of sleep disorders includes cognitive-behavioral therapy considered the mainstay of
non-pharmacologic management of chronic insomnia, and drug treatment with benzodiazepine receptor
agonists binding to gamma aminobutyric acid type A (benzodiazepine and non-benzodiazepine agents)
and some antidepressants. However, observational studies and meta-analyses indicate an increased mortality
risk of anxiolytics and hypnotics, although bias may be involved due to confounding and high
heterogeneity in these studies. Nevertheless, it seems that the risk incurred by the non-benzodiazepine
hypnotic agents (Z drugs) may be relatively less than the risk of anxiolytics, with evidence indicating
that at least one of these agents, zolpidem, may even confer a lower risk of mortality in adjusted models.
All these issues are herein reviewed.

Published: March 2020

Background:

Coinfection of Hepatitis C virus (HCV) with human immunodeficiency
virus (HIV) has a higher risk of mortality than HCV or HIV monoinfection. HCV and HIV infections
are specified by systemic inflammation, but the inflammation process in HCV/HIV coinfection
is much complicated and is not well characterized.

Objective:

The aim of this study was to analyze the expression of TLR-3, TLR-7, IL-10, IFN-1
(IFN-α, IFN-β), and TNF-α in HIV, HCV and HIV/HCV co-infected patients.

Methods:

Forty-five patients including HIV group (n=15), HCV group (n=15), HIV/HCV coinfection
group (n=15) and healthy control group (n=15) participated. Peripheral blood mononuclear
cells (PBMCs) were obtained. PBMC-RNA, HCV and HIV RNA were extracted from all subjects
and cDNA was synthesized. The viral load analyzed by reverse transcription-quantitative PCR
(RT-qPCR), and the expression levels of IFN-α, IFN-β, TLR-3, TLR-7, TNF, and IL-10 mRNA
were quantified in PBMCs.

Results:

The levels of IFN-I, IL-10, and TNF-α were overexpressed in all patients’ groups
(P<0.05), TLR-7 was upregulated in all groups, but this upregulation was not statistically significant
(p>0.05). TLR-3 showed a decrease in all patient groups (P<0.05). The statistical analysis
demonstrated that TLR-3 has a negative correlation with HIV load, whereas other genes positively
correlated with HIV load. In addition, TLR-3, TNF-α, and IFN-I were negatively correlated with
HCV load, whereas TLR-7 and IL-10 s were positively correlated with HCV load.

Conclusion:

Our results showed a significant relationship between the expression level of innate
immunity genes and inflammation in HCV, HIV, and HIV/HCV coinfected patients.

Direct measurement of the magnetocaloric effect ΔTad in the Ni49.3Mn40.4In10.3 Heusler alloy was performed in cyclic magnetic fields with an amplitude up to 8 T. The maximum value of the magnetocaloric effect is - 5.29 K near the martensite – austenite phase transition and 3.39 K at the ferromagnetic-paramagnetic phase transition in the austenite phase. It was found that the long-term effect of a cyclic magnetic field results in a noticeable decrease in the MCE value in the region of the magnetostructural phase transition. The recovery of the initial properties occurs after the complete transformation of the sample into the austenite phase. The discovered phenomenon limits the use of these materials in magnetic cooling technology.

Hot Filament Chemical Vapor Deposition technique was used to synthesize diamond particles with germanium-vacancy color centers on a germanium substrate. The formation of color centers occurred during the growth of diamond particles due to the incorporation of germanium atoms formed as a result of a crystalline germanium wafer etching with atomic hydrogen. The conditions of Chemical Vapor Deposition process which affect the photoluminescence of color centers of germanium vacancy in diamond particles, are considered. The highest photoluminescence intensity of germanium-vacancy color centers was achieved for diamond particles obtained on a substrate at a surface temperature close to the melting temperature of germanium. The photoluminescence spectra of the diamond particles also showed lines presumably associated with the optical centers which contain tungsten.

Abstract
Experimental data on the effect of mechanical loading (tension and compression) of glassy polymethylmethacrylate and polyvinyl chloride on low-frequency IR and Raman spectra are obtained. Their analysis made it possible to detect absorption and scattering due to low-energy orientational excitations in a disordered polymer exposed to external influences. It was shown that these spectral data carry information on the molecular mechanisms of deformation and the relaxation dynamics of macromolecules. A possible scenario of the development of the initial stage of the deformation process is considered.

In this paper, we have studied the dependencies of group velocity and damping of magnetoelastic surface waves on the frequency at various external magnetic fields and propagation angles. The group velocity spikes occur at frequencies at which the damping peaks of the surface wave are detected. The behavior of a surface magnetoelastic wave in the vicinity of the orientational phase transition was also investigated. At the phase transition point, the group velocity changes by 1%. Dependences of the damping along the surface at various propagation angles point out on the nonreciprocal nature of the wave. All dependencies in this work were obtained using computer modeling. The parameters of the ferromagnet are taken typical for yttrium-iron garnet.

This work is devoted to studying the structure and magnetic properties of FeRhl-xIrx (x = 0.5, 0.625, 0.75, 0.875, 1) alloys using first-principle methods using the VASP software package. Two types of structure (CuAu and CsCl) were considered in the work. The equilibrium lattice parameters, total energies and magnetic moments, and also total and partial densities of states for Fe-Rh-Ir were obtained. It was shown that an antiferromagnetic structure with a spin configuration of the AFM-III type is energetically favorable for all the studied alloys.

In the NiFe/Ta/IrMn structures, the contributions of two types of exchange interactions are separated at the NiFe/IrMn interface, partially separated by non-magnetic Ta fragments. The first “contact” exchange corresponds to the NiFe/IrMn fragments. The second “interlayer” exchange is provided by the Ta conduction electrons in the NiFe/Ta/IrMn fragments. A comparison of the temperature dependences of the exchange bias in heterostructures with varied Ta spacer at fixed parameters of the ferromagnetic layers allowed us to separate the contributions of the above types of exchange interactions and to establish their temperature dependences. The energies of the exchange interactions in the NiFe/IrMn and NiFe/Ta/IrMn fragments were determined.

The heat capacity and permittivity of Bi0.8Ho0.2FeO3 multiferroics were studied in a wide temperature range of 300--750 K. It was found that doping with holmium with rare-earth element leads to significant changes in the temperature dependences of the specific heat Cp and permittivity ε 'at high temperatures. It is shown that an additional contribution to the specific heat can be interpreted as a Schottky anomaly for three-level states arising due to distortion of the lattice parameters upon doping. An additional anomaly characteristic of the phase transition was found in the temperature dependences of Cp and ε '. Research results are discussed in conjunction with structural studies.

The emission variation of SSE from surface fragments of protrusions in a silicon plate is evaluated during prolonged scanning in low energy SEM. Emission dynamic variation that is especially complex near the edges of protrusion upper bases and slopes is discovered that affects the sizes of all protrusion fragments. Emission variation is explained with changes of unevenly localized charge state at different surface fragments of protrusions in a natural silica and a contamination film. Contamination is occurred in vacuum and depends on a surface charge state so it is not uniform along protrusion surface. The total absence of contamination on some protrusions is fixed so its initial linewidth size is occurred a constant during a scanning. The limiting uprising of a linewidth size to 4.5 at a one case and the limiting decrease to -0.8 at another case are fixed.

Cardiac Rehabilitation Sustainability by Utilization of Accelerometer and Low-Frequency Text Messaging (Preprint)
Authors: Rodder Susan , Gonzalez Venessa , Harris Theresa
Published: March 2020

BACKGROUND

Participation in outpatient cardiac rehabilitation (CR) Phase II reduces morbidity, mortality, and improves the quality of life. After Phase II, patients enter Phase III where they attempt to maintain the heart-healthy lifestyle learned during CR Phase II. Despite the benefits of CR Phase II, adherence to lifestyle recommendations can be challenging to sustain in Phase III. The use of mobile health (mHealth) technologies (accelerometer, text messaging, self-monitoring, etc.) can impact adherence and cardiovascular health; however, the impact of utilization frequency of text messaging on CR sustainability should be assessed.

OBJECTIVE

This trial aimed to determine CR sustainability, at 12 weeks post CR Phase II, by utilization of i) accelerometer, and ii) text messaging either at a) low-frequency with minimal supportive content or b) high-frequency with enhanced supportive content.

METHODS

The trial was a single-blinded randomized controlled trial with a 2-arm parallel group design. 42 participants were randomized to receive text messaging either a) bi-monthly (low-frequency group; N=22), with text messages being reminders of study participation and the date for the 12-week assessment; or b) tri-weekly (high-frequency group; N=20), with text messages being educational (nutrition, exercise, medication compliance) or supportive (encouragement). All participants were instructed to track steps using accelerometers (Fitbit, Smartphone, Smartwatch, etc.). A 6-minute walk test was used to determine physical fitness as measured by metabolic equivalents (METs). Rate Your Plate (RYP) scores, body mass index (BMI), weight, and waist-to-hip ratio (W:H) were used to assess dietary compliance.

RESULTS

Two-way repeated measure of analysis of variance found that the high-frequency and low-frequency group had similar sustainability (no decline), with no significant difference in METs (P = .62), RYP scores (P = .15), or BMI (P = .73). However, the high-frequency group did average significantly more steps per week vs. the low-frequency group (52,542  2,611 vs. 43,077  1,550; P = .002).

CONCLUSIONS

This trial showed that CR sustainability at 12-weeks can be achieved with a simple utilization of mobile health (mHealth) technology (accelerometer and low-frequency text messaging), thus eliminating the decline in fitness and dietary compliance often seen at 12-weeks post-CR Phase II.
