Severe Biomass-Burning Aerosol Pollution during the 2019 Amazon Wildfire and Its Direct Radiative-Forcing Impact: A Space Perspective from MODIS Retrievals
Authors: Yuan Shuyun , Bao Fangwen , Zhang Xiaochuan , Li Ying
Published: April 2022

An extreme biomass burning event occurred in the Amazonian rainforest from July through September 2019 due to the extensive wildfires used to clear the land, which allowed for more significant forest burning than previously occurred. In this study, we reclustered the clear-sky ambient aerosols to adapt the black carbon (BC) aerosol retrieval algorithm to Amazonia. This not only isolated the volumetric fraction of BC (fbc) from moderate-resolution imaging spectroradiometer (MODIS) aerosol data, but also facilitated the use of aerosol mixing and scattering models to estimate the absorption properties of smoke plumes. The retrieved MODIS aerosol dataset provided a space perspective on characterizing the aerosol changes and trends of the 2019 pollution event. A very high aerosol optical depth (AOD) was found to affect the source areas continuously, with higher and thus stronger aerosol absorption. These pollutants also affected the atmosphere downwind due to the transport of air masses. In addition, properties of aerosols emitted from the 2019 Amazonian wildfire events visualized a significant year-to-year enhancement, with the averaged AOD at 550 nm increased by 150%. A 200% increase in the aerosol-absorption optical depth (AAOD) at 550 nm was recognized due to the low single-scattering albedo (SSA) caused by the explosive BC emissions during the pollution peak. Further simulations of aerosol radiative forcing (ARF) showed that the biomass-burning aerosols emitted during the extreme Amazonian wildfires event in 2019 forced a significant change in the radiative balance, which not only produced greater heating of the atmospheric column through strong absorption of BC, but also reduced the radiation reaching the top-of-atmosphere (TOA) and surface level. The negative radiative forcing at the TOA and surface level, as well as the positive radiative forcing in the atmosphere, were elevated by ~30% across the whole of South America compared to 2018. These radiative effects of the absorbing aerosol could have the ability to accelerate the deterioration cycle of drought and fire over the Amazonian rainforest.

Fluctuations in illumination are one of the major sources for SIF retrieval errors during temporal continuous field measurements. In this study, we propose a method for evaluating the quality of SIF based on simultaneous measurements of photosynthetically active radiation (PAR), which are acquired using a quantum sensor at a sampling frequency higher than that obtained using spectral measurements. The proposed method is based on the coefficient of variation (known as relative standard deviation) of the high-frequency PAR during a SIF measurement to determine the quality of the SIF value. To evaluate the method, spectral and PAR data of a healthy maize canopy were collected under various illumination conditions, including clear, cloudy, and rapidly fluctuating illumination. The SIF values were retrieved by 3FLD, SFM, and SVD. The results showed that SFM and 3FLD were sensitive to illumination stability. The determination coefficients (R2) between PAR and SIF extracted by SFM and 3FLD were higher than 0.8 on clear and cloudy days and only approximately 0.48 on the day with rapidly fluctuating illumination. By removing the unqualified data using the proposed method, the R2 values of SFM and 3FLD on the day of rapidly fluctuating illumination significantly increased to 0.72. SVD was insensitive to illumination stability. The R2 values of SVD on days with clear, cloudy, and rapidly fluctuating illumination were 0.73, 0.76, and 0.61, respectively. By removing the unqualified data, the R2 values of SVD were increased to 0.66 on the day with rapidly fluctuating illumination. The results indicated that the quality assessment method based on high-frequency PAR data can eliminate the incorrect SIFs due to unstable illumination. The method can be used to extract more accurate and reliable SIF datasets from long-term field observations for the study of the relationship between SIF and vegetation photosynthesis.

Published: April 2022

As clean, renewable energy, photovoltaic (PV) energy can reduce the ozone-layer loss and climate deterioration caused by the use of traditional types of energy to generate electricity. At present, most PV energy products involve the influence of cloud cover on solar radiation. However, the resolution and precision of most cloud cover data are not fine enough to reflect the actual cloud distribution in local areas. This leads to incorrect distribution results of PV energy in areas with high-spatial-variability clouds. Using high-resolution and high-precision cloud cover data obtained by satellite remote sensing to estimate the distribution of PV energy can solve this problem. In this study, the Global Land High-Resolution Cloud Climatology (GLHCC), a 10-day cloud frequency product with a resolution of 1 km and located in China, was used to construct a cloud-based solar radiation estimation model. Using the inverse relationship between cloud cover and solar radiation, the GLHCC was converted into sunshine percentage data. Using meteorological station data in China, a Least Squares Fit (LSF) and error check were carried out on the A-P, Lqbal, Bahel and Sen Models to determine the optimal solar radiation estimation model (Sen Model). Based on the sunshine percentage data, the Sen Model and terrain shielding factors, the distribution of PV energy in China was estimated. Finally, comparing to the Global Horizontal Irradiance (GHI) of the World Bank and the yearly average global irradiance of the Photovoltaic Geographic Information System (PVGIS), PV energy data in this paper more accurately reflected the distribution of PV energy in China, especially in areas with high-spatial-variability clouds.

Effect of Leak Geometry on Water Characteristics Inside Pipes
Authors: Ali Sajid , Hawwa Muhammad A. , Baroudi Uthman
Published: April 2022

Water leaks from pipelines have large economic and ecological impacts. Minimizing water loss from supply pipelines has favorable effects on the environment as well as on energy consumption. This paper aims to understand the effect of the geometry of a leaking crack in a pipe wall by examining fluid flow characteristics, namely pressure and velocity distributions, inside the pipe. Practical observations show that the cause of wall rupture influences the geometry of cracks formed in a pipe wall, impacting aspects such as excessive pressure, corrosion. Knowledge of fluid flow characteristics could help in detecting and identifying leak characteristics at an early stage and assist in improving the energy and resource efficiency of water supply services. An experimental setup is developed to detect water leakage in a pipe when the leak is at an early stage and is difficult to detect by visual inspection. A computational fluid dynamic (CFD) model is developed using the COMSOL software. A comprehensive analysis of the effect of leak geometry on pressure and velocity distributions along the pipe is carried out while considering factors such as different pipe sizes, leak geometries, and steady-state flow conditions. It is observed that both velocity and pressure magnitudes rapidly fluctuate in the vicinity of leaks. Leaking cracks with slot, circle, and square shapes are found to generate distinguishing pressure and velocity distributions along the pipe. Thus, the geometry of the leaking crack and potentially its root cause(s) could be predicted by measuring velocity and pressure distributions.
A Simplified Method for BIPV Retrofitting of Emirati Public Housing with Preserved Architectural Identity: A Pilot Study
Authors: Galal Ahmed Khaled , Megahed Mona
Published: April 2022

The United Arab Emirates (UAE) has tailored its own sustainability initiatives and a local agenda for realizing Sustainable Development Goals (SDGs) by 2030. This Agenda includes providing clean sustainable energy and achieving sustainable communities. In accordance with these efforts, this ‘pilot’ study aims at, first, exploring an appropriate, simplified method of integrating photovoltaic (PV) panels in existing single-family public housing in the UAE without compromising the architectural style and identity of the original designs. Second, it aims at assessing the sufficiency of the generated electricity through this proposed Building Integrated Photovoltaic (BIPV) system. Finally, it aims at conducting a pilot survey to explore the Emirati residents’ acceptance of the proposed BIPV system. A frequently developed design model of single-family public housing projects in the UAE was selected to undertake the research investigations where the most suitable architectural elements of its envelope were defined for accommodating the integrated PV panels. Afterwards, a complete set of BIPV panel designs tailored to fit with the defined architectural elements of the selected house was prepared. The dimensions and areas of the BIPV panels were defined and digitally constructed through Building Information Modeling (BIM) software. After considering the efficiency and adequacy of the selected type of BIPV panels and figuring out the expected system losses, the PVWatts Calculator was used for simulating the expected electricity output in kilowatt hours (kWh) for the four façades of the selected model house in their four possible different orientations, as well as the overall average electricity output from the whole BIPV system. The results of the yearly electricity output were very close regardless of the orientation of the four façades of the retrofitted model house, with the total average annual output exceeding the estimated yearly average electricity consumption of this model house. This obviously indicates the potential benefit of the proposed BIPV system, especially with the continuous decrease in the capital cost of the PV panels and their increasing efficiency. With the Emirati residents’ clear acceptance of the proposed BIPV system, it might be also considered as an efficient alternative to the currently limited application of rooftop PV solutions in the UAE.

Published: April 2022

To address the problem of subjectivity in determining the poverty-returning risk among registered poor households, a method of monitoring and analyzing the poverty-returning risk among households based on BP neural network and natural breaks method was constructed. In the case of Yunyang District, Hubei Province, based on the data of the poverty alleviation and development system, we constructed a monitoring system for the poverty-returning risk for the registered poor households. The spatial distribution pattern of households under the poverty-returning risk was analyzed from two scales of district and township, respectively, by combining Geographic Information Science, and the influence degree of indicators on the poverty-returning risk using mean impact value (MIV). The results show that: (1) The spatial distribution of the poverty-returning risk among the registered poor households in the study area basically coincides with the local natural poverty-causing factors and the degree of social and economic development. (2) The Poverty-Returning Risk Index for each township represents a globally strong spatial dependence with a Moran’s I coefficient of 0.352. (3) The past poverty identification status of registered poor households is the main factor to reduce the poverty-returning risk, and the past policy should remain unchanged for a period of time. (4) Improving the quality of education within households and focusing on helping households with older average age can further reduce the poverty-returning risk.

Published: April 2022

Resilience and sustainability are two critical factors in supply chain networks (SCNs) to assure business continuity and achieve competitive advantages. Due to the dynamic interconnections between the several parts that comprise a typical SCN such as customers, organizations, sites, departments, geographies, and so on, efficient collaboration between all parts is vital to assure business success, especially in times of uncertainty and unpredictable disruption. Collaborative risks such as poor communication, deficient information exchange, lack of trust, lack or deficient access or reach, just to name a few, that essentially emerge as a result from a shift toward one of the extremes of the collaborative dimension (lack of collaboration or collaborative overload) are very often invisible; however, they are responsible for undesired outcomes such as production defects and delivery delays, just to name a few. In this work, a strategic process to identify and manage collaborative risks in SCNs to help improve resilience and sustainability is proposed. The proposed strategic process analysis contains three key SCN’s collaborative dimensions ((1) network access or reach, (2) trust, and (3) communication) applying graph centrality metrics, looking for emergent collaborative risks in a quantitative way that potentially may threaten an organization’s efficiency and performance, and thus negatively impact resilience and sustainability. A case study conducted in the middle of the COVID-19 pandemic is illustrated to describe how organization benefit regarding the timely and quantitative identification of potential behavioral patterns that lead to one of the collaborative extremes. The results show that the application proposed strategic process is very successful in ensuring sustainability improving resilience of SCNs.
Engaging Communities in Adaptation to Climate Change by Understanding the Dimensions of Social Capital in Atlantic Canada
Authors: Vasseur Liette , Thornbush Mary J. , Plante Steve
Published: April 2022

This paper examines the role of social capital and its influence on the capacity of coastal communities in Atlantic Canada to respond and adapt to climate change, especially when dealing with extreme weather events. Three elements of social capital—social trust, institutional trust, and social networks—were considered. They were analyzed based on four questions targeting social capital during semi-structured interviews on climate change adaptation in 10 rural coastal communities located in three Canadian provinces (Quebec, New Brunswick, and Prince Edward Island). Results showed that these communities exhibited strong social capital, mainly because of a high level of social trust. People were ambivalent in the way they connected to institutions, especially with governments. They often felt isolated and left to themselves to deal with climate change adaptation decisions. The research conveys the difficulties and challenges of multilevel governance, where coastal communities generally ensure trust within the community first before trusting higher levels of government. Initiatives to improve public engagement and participation in decision making should be supported for further adaptation, although they would require greater accountability and transparency.
The Impact of Prehospital Spinal Immobilization in Patients with Penetrating Spinal Injuries: A Systematic Review and Meta-Analysis
Authors: Alghamdi Ibrahim , Bazaie Naif , Alqurashi Naif , Ahmed Zubair
Published: April 2022

Penetrating injuries, such as gunshot or stab wounds, may cause spinal cord injuries and require prehospital spinal immobilization (PHSI) to stabilize the spine. However, the use of PHSI in penetrating spinal injuries remains controversial. This systematic review aimed to investigate the efficacy of prehospital PHSI in patients with penetrating trauma. We systematically searched Google Scholar, Medline (PubMed), The Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE between January 2000 and July 2021. All studies in English that assessed PHSI in patients (>16 years) with penetrating spinal injuries were included. Quality and risk of bias assessments were performed using the modified Newcastle-Ottawa scale. A narrative synthesis and a meta-analysis was conducted. Our search identified 928 studies but only 6 met our inclusion and exclusion criteria. All of the included studies were conducted in the US and the number of patients ranged from 156–75,567 over 3–9 study years. The majority of patients were gunshot or stab wounds. Three studies demonstrated an increased risk of mortality with spinal collars whilst the remaining three studies failed to show any benefits or the benefits remained unproven. All studies were retrospective studies with some risks of bias. This review highlights that the evidence from the literature on PHSI in penetrating trauma outweigh its benefits; thus, its use is discouraged in penetrating spinal trauma. However, further high-quality research is necessary to reach definitive conclusions and to possibly identify suitable alternatives to PHSI for penetrating spinal trauma.

Coxsackievirus B5 (CVB5) is one of the most prevalent enteroviruses types in humans and causes annual epidemics worldwide. In the present study, we explored viral genetic diversity, molecular and epidemiological aspects of CVB5 obtained from cerebrospinal fluid and stool samples of patients with aseptic meningitis or acute flaccid paralysis, information that is still scarce in Brazil. From 2005 to 2018, 57 isolates of CVB5 were identified in the scope of the Brazilian Poliomyelitis Surveillance Program. Phylogenetic analyses of VP1 sequences revealed the circulation of two CVB5 genogroups, with genogroup B circulating until 2017, further replaced by genogroup A. Network analysis based on deduced amino acid sequences showed important substitutions in residues known to play critical roles in viral host tropism, cell entry, and viral antigenicity. Amino acid substitutions were investigated by the Protein Variation Effect Analyzer (PROVEAN) tool, which revealed two deleterious substitutions: T130N and T130A. To the best of our knowledge, this is the first report to use in silico approaches to determine the putative impact of amino acid substitutions on the CVB5 capsid structure. This work provides valuable information on CVB5 diversity associated with central nervous system (CNS) infections, highlighting the importance of evaluating the biological impact of certain amino acids substitutions associated with epidemiological and structural analyses.

Nephropathia epidemica (NE), a mild form of haemorrhagic fever with renal syndrome (HFRS), is an acute febrile illness caused by Puumala orthohantavirus (PUUV). NE manifests typically with acute kidney injury (AKI), with a case fatality rate of about 0.1%. The treatment and management of hantavirus infections are mainly supportive, although neutralizing monoclonal antibodies and immune sera therapeutics are under investigation. In order to assess the potential use of antibody therapeutics in NE, we sought to determine the relationship between circulating PUUV neutralizing antibodies, PUUV nucleocapsid protein (N) IgG antibodies, and viral loads with markers of disease severity. The study included serum samples of extensively characterized patient cohorts (n = 116) from Tampere University Hospital, Finland. The results showed that upon hospitalization, most patients already had considerable neutralizing and anti-PUUV-N IgG antibody levels. However, contrary to expectations, neutralizing antibody titers from the first day of hospitalization did not appear to protect from AKI or correlate with more favorable disease outcomes. This indicates that further studies are needed to investigate the applicability of neutralizing antibodies as a therapy for hospitalized NE patients.

Dendritic cell (DC) targeting by DEC205+ cells effectively promotes the internalization of antigens that may trigger a specific immune response. In this study, we evaluated the ability of a recombinant antibody, anti-DEC205 (rAb ZH9F7), to trigger cellular endocytosis in subpopulations of DCs and targeted cells after intradermal injection and subsequent migration toward lymph nodes. Furthermore, the cellular immune response was evaluated in pigs after intradermal application of the antigenized rAb ZH9F7 combined with porcine circovirus type 2 cap antigen (rAb ZH9F7-Cap). We demonstrated that rAb ZH9F7 recognized conventional type 1 and 2 DCs from the blood and skin and monocytes. It promoted receptor-mediated endocytosis and migration of cDCs and moDCs toward regional lymph nodes. Intradermal application of rAb ZH9F7-Cap induced a higher frequency of IFN-γ-secreting CD4+CD8+ T lymphocytes and antibodies against Cap protein than that in the control group. In conclusion, the rAb ZH9F7-Cap system promoted the target of skin cDC1 and cDC2, provoking migration to the regional lymph nodes and inducing a Th1 response, as evidenced by the proliferation of double-positive CD4+CD8+ T cells, which correlates with an enhanced ability to target the cDC1 subset both in vitro and in vivo.

Background: We aimed to evaluate the perfusion index (PI) level at the 10th minute of admission to the emergency department in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina pectoris (USAP). In addition, we aimed to evaluate whether PI is useful in differentiating NSTEMI and USAP patients in the emergency department in the early stage.Materials and Methods: Eighty NSTEMI (Group 1) and 50 USAP (Group 2) patients who were consecutively admitted to our emergency department between November 2017 and May 2019 and diagnosed with acute coronary syndrome were included in the study. In both patient groups, PI measured with the Massimo-SET Root 7362A RDS7 non-invasive pulse oximetry probe and other routine laboratory measurements were measured and compared.Results: The mean PI was significantly lower in NSTEMI patients (p <0.001). At 30-day patient follow-up, the PI of the reduce was significantly lower (P <0.001). The area under the curve was significantly lower for PI in NSTEMI patients (area under the curve 0.313, p = 0.016). At 30-day patient follow-up, the level of PI was significantly lower in the died patients than the survived patients (P <0.001). The area under the curve was significantly lower for PI in NSTEMI patients (area under the curve 0.313, p = 0.016).Conclusions: Although our study shows that PI may be an early marker in the distinguish of NSTEMI and USAP patients and may be useful in predicting the mortality of these patients, more extensive studies will support our hypothesis.

Published: April 2022

Administrar el conocimiento organizacional representa una ventaja clave en las empresas de software. Para que dicha administración sea eficiente es importante contar con una Memoria Organizacional que de soporte a la captura, estructuración, reuso y diseminación del conocimiento creado por sus empleados. La utilidad de una Memoria Organizacional radica en que el conocimiento que almacena pueda ser fácilmente compartido entre sistemas dentro de la organización o entre organizaciones colaborativas. En esta tesis mostramos cómo se puede implementar una Memoria Organizacional Basada en Ontologías y Casos que administre en forma consistente, automática y distribuída el conocimiento presente en una empresa. A medida que el área de Gestión del Conocimiento va progresando hacia una disciplina más madura, se van obteniendo importantes resultados de investigación relacionados a Memoria Organizacional, Gestión del Conocimiento y Razonamiento Basado en Casos. Sin embargo, se observa que el desarrollo rápido y caótico de tanta información relacionada a estas áreas, proveniente de fuentes heterogéneas, y la falta de consenso en la terminología utilizada, dificulta su aplicación y reuso de forma eficiente en los procesos de Gestión del Conocimiento. Con el propósito de dar solución a esta problemática, uno de los aportes de esta tesis es proveer una conceptualización del dominio de Memoria Organizacional Basada en Casos (MOBC) que se formaliza en una Ontología para dicho ámbito. La Ontología de MOBC, combina aspectos de Memoria Organizacional con Razonamiento Basado en Casos para representar cada ítem de conocimiento informal. La estructuración del conocimiento informal en casos, facilita la captura, transferencia, y reuso a través de un procesamiento automático. La ontología propuesta, es usada como base para el diseño y construcción de un sistema de Memoria Organizacional Basada en Casos y un sistema de recomendación para proyectos de medición y evaluación en aseguramiento de calidad, que usa la MOBC como su componente central. En Ingeniería de Software/Web, el aseguramiento de la calidad y como consecuencia la medición y evaluación, son procesos de soporte claves para el desarrollo y mantenimiento de aplicaciones de software. Por lo tanto la administración en forma consistente y eficiente del conocimiento relacionado a dichos proyectos es muy importante para la toma de decisiones, el reuso y la recomendación en nuevos proyectos, tomando ventaja de las experiencias anteriores, lecciones aprendidas y las buenas prácticas.

Environmental awareness of the community on natural resources such as water, air, and soil as crucial items for the survival of human life is very low. Today, humans are overexploiting nature. Volunteers of paver blocks and eco-bricks making at Saung Angklung Udjo found that paving construction can reduce environmental pollution by plastic waste which cannot be decomposed in nature. Therefore, one of the factors of environmental awareness is the existence of government policies that become a reference in every movement in the community. Another factor is the community participation. This is because of the nature conservation process is not automatically done. The current study is a quantitative research with descriptive methods. Questionnaires and SPSS 17.0 software program were employed as the research instruments. In this study, it was revealed that government policies have an impact of 31.1% and the public participation shows on environmental awareness shows 32,2%. The results of the study show that there are other factors that may affect environmental awareness.

Since the Covid-19 pandemic has paralyzed the activities of the Indonesian people, it has greatly affected the course of educational activities. Education, which is a forum for the nation's next generation, in this very limited situation becomes a very big obstacle, not least the Teaching and Learning Activities experienced by elementary schools, precisely at SDN Balunglor 06 in Balung village. Teaching and learning activities were initially carried out in schools with a fairly effective time, the intended effectiveness was that the learning time and subject matter obtained by students was orderly and directed, now students and teachers are only allowed to take part in teaching and learning activities for only a few hours, students come to homeroom teacher as a location for teaching and learning activities. The purpose of this study was to determine the effectiveness of learning during the Covid-19 pandemic, to assist teaching and learning activities, as well as a form of teaching service from OFFDA KKN students. This service method uses the Asset Based Community Development (ABCD) method. The location of the service is at SND Balunglor 06 Balung Village, Jember Regency. Researchers have carried out observations and assisted in religious learning at SDN Balunglor 06. As a result of this service, the authors provided assistance in religious education and tried to inspire students' enthusiasm for learning by participating in teaching and learning activities at SDN Balunglor 06.

Published: April 2022

Los sistemas de ecuaciones lineales (SEL) corresponden a un concepto fundamental del álgebra lineal, pero hay relativamente poca investigación, pero hay relativamente poca investigación acerca de la enseñanza y el aprendizaje de los SEL, particularmente de las concepciones de los estudiantes acerca de sus soluciones. Se ha encontrado que la resolución de sistemas con un número infinito de soluciones o sin solución tiende a ser menos intuitivo para los estudiantes, lo cual indica la necesidad de más investigación en la enseñanza y aprendizaje de este tema. Entrevistamos a dos estudiantes de matemáticas que eran también maestros en formación a través de un experimento de enseñanza por parejas para mirar cómo razonaban acerca de las soluciones de SEL en ℝ3. Presentamos los resultados enfocando en la progresión del razonamiento de los estudiantes sobre las soluciones de los SEL a través del lento de simbolización. Documentamos la progresión de su razonamiento como una acumulación de significados numéricos, algebraicos y gráficos coordinados y las simbolizaciones de sus conjuntos solución.
Mathematical reasoning in linear systems learning: a higher education exploratory teaching experiment with prospective teachers
Authors: Henriques Ana , Márcio Martins
Published: April 2022

Higher education students show difficulties on concepts in linear systems, due to procedural-dominated teaching practices. This emphasizes the need to develop students’ mathematical reasoning using an exploratory teaching approach to promote learning with understanding. This qualitative and interpretative study analyzes the mathematical reasoning that prospective teachers, attending the degree in mathematics, use in solving research tasks involving linear systems, proposed throughout an exploratory teaching experiment and how this context contribute to their learning. Data collection includes participant observation of the teaching experiment classes, and written work of the proposed tasks. The results show that prospective teachers have evolved positively in their understanding and capacity of mathematical reasoning, and in the linear systems learning. The evidenced advantages of this experiment may contribute to a reflection on this integration to improve educational contexts, including preservice teacher education, to overcome their difficulties in learning and develop their knowledge for teaching.

Obesity and heart failure with preserved ejection fraction: pathophysiology and clinical significance
Authors: Lee Da Young
Published: April 2022

Obesity is a risk factor for heart failure and cardiovascular disease. Of particular note, over 80% of patients with heart failure with a preserved ejection fraction (HFpEF) are overweight or obese. In this study, we aimed to review the association between obesity and HFpEF. Obese patients with HFpEF exhibit a distinct phenotype. In addition to impaired left ventricular (LV) diastolic function and high filling pressures, obese patients with HFpEF possess other factors that cause elevated LV filling pressure, such as a greater dependence on plasma volume expansion, aggravated pericardial restraint, and increased ventricular interaction. Obesity can contribute to HFpEF through hemodynamic, neurohormonal, inflammatory, and mechanical mechanisms. An increased amount of body fat can induce plasma volume expansion, resulting in chamber remodeling, pericardial restraint, and ultimately elevations in LV filling pressure. Obesity can mediate the activation of sympathetic nervous system signaling and the renin-angiotensin-aldosterone system. These unique pathophysiological characteristics of individuals with both obesity and HFpEF suggest that obesity with HFpEF can be considered a specific phenotype. Future research is expected to clarify effective treatment modalities for obesity-related HFpEF.
