Authors: La Nasa Giorgio , Caocci Giovanni , Morelli Emanuela , Massa Elena , Farci Antonio , Deiana Laura , Pintus Elisa , Scartozzi Mario , Sancassiani Federica
Published: July 2020

Background:

HRQoL is generally conceptualized as a broad multidimensional construct that refers to patients' perceptions of the impact of disease and its treatment on their physical, psychological, and social functioning and well-being. Little is known in patients with onco-hematological cancer in comparison with the general population and other chronic diseases.

Objective:

We assessed HRQoL in patients diagnosed with haematological cancers in comparison with the general population and other chronic diseases.

Methods:

The questionnaire Short Form (SF)-12 was administered to 62 patients with onco-hematological disease and results were compared with 702 controls (184 healthy people, 37 Major Depression, 201 Multiple Sclerosis; 23 Wilson disease; 46 Carotidal Atherosclerosis; 60 Celiac disease; 151 solid tumours).

Results:

HRQoL in patients diagnosed with a haematological cancer was significantly worse in comparison with the general population (F= 43.853, p <0.00001) but similar when compared with solid tumour and other chronic diseases such as Major Depression and Carotid Atherosclerosis. In addition, HRQoL in patients diagnosed with a haematological cancer was significantly higher than that due to Celiac disease (p <0.00001) and Wilson's disease (p= 0.02), and lower than that due to Multiple Sclerosis (p= 0.032).

Conclusion:

This study confirmed that haematological cancers negatively affects overall HRQoL. The results showed an impact of haematological cancers on HRQoL that is similar to what found in patients with solid tumors, Major Depression and Carotid Atherosclerosis. Current successful therapeutic strategy achieved in the treatment of haematological cancers not only positively impact on survival rate but also could improve the overall HRQoL.

Authors: Coelho Olga , Pires Rute , Ferreira Ana Sousa , Gonçalves Bruno , AlJassmi Maryam , Stocker Joana
Published: July 2020

Background:

Section III of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) proposes a model for conceptualizing personality disorders in which they are characterized by impairments in personality functioning and maladaptive personality traits. The Personality Inventory for DSM-5 (PID-5) is a self-report measure that assesses the presence and severity of these maladaptive personality traits.

Objective:

The current study examined the reliability and validity of the Arabic version of the Personality Inventory for DSM-5 (PID-5) to measure maladaptive personality traits in the Emirati population of the United Arab Emirates.

Methods:

The Arabic version of the PID-5 was administered to a community sample of 1,090 United Arab Emirates nationals (89.5% female and 10.5% male, mean age = 22.44 years old). The descriptive measures, internal consistency, test-retest reliability, convergent validity with NEO – Five Factor Inventory, as well as PID-5’s factor structure, were all addressed.

Results:

The PID-5facets and domains mean scores were higher in the Emirati sample compared to the original US sample. Internal consistency of the PID-5 scales was acceptable to high and test-retest coefficients ranged from 0.84 (facets) to 0.87 (domains). As expected, the five domains of the Arabic version of the PID-5 correlated significantly with all Five-Factor Model domains of personality. Additionally, the Arabic version of the PID-5 confirmed a five-factor structure that resembles the PID-5 domains.

Conclusion:

The findings of this study provided initial support for the use of the Arabic version of the PID-5 to assess maladaptive personality traits in the Emirati population of the United Arab Emirates.
Vitamin D as a Potential Therapeutic Option in Cancer Treatment: Is There a Role for Chemoprevention?
Authors: Bahrami Afsane , Sahebkar Amirhossein
Published: July 2020

Background:

Vitamin D (Vit D) serves as a precursor to the potent steroid hormone calcitriol, which
regulates numerous genes that control homeostasis, epithelial cell differentiation, proliferation, and apoptosis.
Low level of Vit D is implicated in the development and progression of several diseases including bone fractures,
cardiovascular disease, diabetes mellitus, and cancers. The present review highlights the role of vitamin D
in cancer with a particular emphasis on genetic variants related to Vit D metabolism as well as clinical trials of
Vit D supplementation as a potential therapeutic option in the treatment of cancer patients.

Methods:

Data were collected following an electronic search in the Web of Science, Medline, PubMed, and
Scopus databases by using some keywords such as “cancer”, “tumor”, “malignancy”, “vitamin D”, “cholecalciferol”
and “calcitriol”.

Results:

The collected evidence from the studies revealed a consistent and strong association between Vit D
status and cancer risk and survival. The associations between Vit D-related genetic variants and cancer survival
support the hypothesis that Vit D may affect cancer outcomes. The mechanisms whereby Vit D reduces cancer
risk and increases survival are regulation of cellular differentiation, proliferation and apoptosis as well as decreased
angiogenesis in tumor microenvironment and inhibition of metastasis.

Conclusion:

There is a paucity of evidence-based recommendations for the optimal 25(OH)D levels in patients
with cancer and the role of Vit D supplementation for primary or secondary prevention of cancer. Well-designed
and sufficiently powered randomized clinical trials are necessary to assess the clinical application of Vit D in
enhancing the clinical efficacy of standard and adjuvant chemotherapy regimens.
Biological Evaluation of Synthesized Naringenin Derivatives as Antimicrobial Agents
Authors: Murti Yogesh
Published: July 2020

Background:

Flavonoids are among the most abundant plant secondary metabolites and
have been shown to have natural abilities as microbial deterrents and anti-infection agents in
plants. Naringenin as one of the flavonoids and its derivatives have been reported to exhibit antimicrobial
activity.

Aims:

The aim of the study was to evaluate synthesized novel naringenin derivatives (ND-1 to ND-
12) substituted at 3-position with bulky substituent by using the grinding technique (Claisen-
Schmidt reaction) as antimicrobial agents.

Methods:

Synthesized naringenin derivatives were evaluated for in-vitro antimicrobial activity by
“Agar disc diffusion method”.

Results:

Novel naringenin derivatives showed mild to moderate antimicrobial activity with respect
to standard drugs against two gram-positive, two gram-negative bacteria and two fungal strains.
The substitution of naringenin derivatives at position 3 with substituted phenyl rings showed variation
in activity as chloro, nitro and hydroxyl-substituted phenyl ring showed potent activity while
methoxy substituted phenyl ring impede the activity.

Conclusion:

In conclusion, on the basis of the above findings, the substituted naringenin scaffolds
may be selected as a skeleton for the development of flavonoid structurally-related compounds
having antimicrobial activity.

Fernandoa adenophylla (Heterophragma adenophyllum), commonly known as Dhopa-
phali, Ziron, Mostan-phul, Lotum-poh and Karen wood of family Bignoniaceae, has been used
traditionally for snakebite (Morigaon district of Assam, India), hemorrhoids and constipation
(Chakma tribe, Bangladesh) and skin disorder (Thai traditional medicine). This review covers pharmacognostic,
phytochemical, and pharmacological as well as the traditional aspects of the plant
and enlightens possible pharmacological activities Received: that can be assessed in the future. Fernandoa
adenophylla has been reported to constitute potent phytochemicals like novel napthaquinones,
their derivatives (dilapachone, adenophyllone, peshwaraquinone, lapachol, and indadone)
and triterpenoids (β-sitosterol, β-amyrin, ursolic acid, and oleanolic acid) which have potential
pharmacological activities that have been assessed and reported. The Crude extract of Fernandoa
adenophylla has already been tested for pharmacological properties like antimicrobial, antifungal,
anti-TB, and antihypertensive and leishmanicidal activities. Since not many researches have been
carried out on Fernandoa adenophylla, it paves way for researchers to explore its potential in the
field of medicinal plants.
Evaluation of Korean-Language COVID-19–Related Medical Information on YouTube: Cross-Sectional Infodemiology Study
Authors: Moon Hana , Lee Geon Ho
Published: July 2020

Background

In South Korea, the number of coronavirus disease (COVID-19) cases has declined rapidly and much sooner than in other countries. South Korea is one of the most digitalized countries in the world, and YouTube may have served as a rapid delivery mechanism for increasing public awareness of COVID-19. Thus, the platform may have helped the South Korean public fight the spread of the disease.

Objective

The aim of this study is to compare the reliability, overall quality, title–content consistency, and content coverage of Korean-language YouTube videos on COVID-19, which have been uploaded by different sources.

Methods

A total of 200 of the most viewed YouTube videos from January 1, 2020, to April 30, 2020, were screened, searching in Korean for the terms “Coronavirus,” “COVID,” “Corona,” “Wuhan virus,” and “Wuhan pneumonia.” Non-Korean videos and videos that were duplicated, irrelevant, or livestreamed were excluded. Source and video metrics were collected. The videos were scored based on the following criteria: modified DISCERN index, Journal of the American Medical Association Score (JAMAS) benchmark criteria, global quality score (GQS), title–content consistency index (TCCI), and medical information and content index (MICI).

Results

Of the 105 total videos, 37.14% (39/105) contained misleading information; independent user–generated videos showed the highest proportion of misleading information at 68.09% (32/47), while all of the government-generated videos were useful. Government agency–generated videos achieved the highest median score of DISCERN (5.0, IQR 5.0-5.0), JAMAS (4.0, IQR 4.0-4.0), GQS (4.0, IQR 3.0-4.5), and TCCI (5.0, IQR 5.0-5.0), while independent user–generated videos achieved the lowest median score of DISCERN (2.0, IQR 1.0-3.0), JAMAS (2.0, IQR 1.5-2.0), GQS (2.0, IQR 1.5-2.0), and TCCI (3.0, IQR 3.0-4.0). However, the total MICI was not significantly different among sources. “Transmission and precautionary measures” were the most commonly covered content by government agencies, news agencies, and independent users. In contrast, the most mentioned content by news agencies was “prevalence,” followed by “transmission and precautionary measures.”

Conclusions

Misleading videos had more likes, fewer comments, and longer running times than useful videos. Korean-language YouTube videos on COVID-19 uploaded by different sources varied significantly in terms of reliability, overall quality, and title–content consistency, but the content coverage was not significantly different. Government-generated videos had higher reliability, overall quality, and title–content consistency than independent user–generated videos.
Virtual Overdose Response for People Who Use Opioids Alone: Protocol for a Feasibility and Clinical Trial Study (Preprint)
Authors: Bristowe Sean Kristina , Ghosh Sumantra Monty , Trew Michael ,   Canadian Mental Health Association - Calgary Region, Rittenbach Katherine
Published: July 2020

BACKGROUND

A recent quarterly report released by Alberta Health reports that on average 2.5 Albertans die every day from accidental overdose deaths, and that between April 1, 2020, and June 30, 2020, the province lost a total of 301 people. In Canada, between January 2016 and March 2020, a total of 16,364 people died due to opioid-related overdose. The World Health Organization reports that 70% of the 0.5 million deaths worldwide caused by drugs are related to opioid overdose. Although supervised consumption sites or safe injection sites have been shown to be effective in reducing the harms associated with the use of illicit substances and increasing uptake of addiction treatment and other health services, there is still significant stigma associated with them, and it is unlikely that all of the people who would benefit from supervised consumption service will ever access a site.

OBJECTIVE

To help prevent deaths in populations that cannot or will not access physical safer consumption services in Alberta, we propose to provide virtual (telephone-based) overdose response services, staffed by people with lived experience.The primary outcome for this study is uptake of the service as measured by the number of calls to the service. Secondary outcomes will include patterns of use of the phone line (days of the week and time of calls) and outcomes from the calls (number of emergency medical services dispatches for overdoses from the service and the results of those dispatches).

METHODS

This phase 1 clinical study is set to officially launch in early May 2020. The service will be available to up to 15 participants who self-disclose as using opioids unobserved and have given informed consent for both data collection and interviews. This group will have access to a toll-free telephone number and be invited to call when they plan to use opioids alone.

RESULTS

The analysis will include mixed methods. To improve the design of the service and ensure safety of all involved, quantitative data will be collected on phone calls and participant health care usage, while qualitative data will be collected from both participants and virtual overdose response operators

CONCLUSIONS

This clinical trial aims to test the feasibility of a service that provides virtual overdose response in order to help prevent deaths in populations that cannot or will not access physical supervised consumption services in Alberta.

Virtual anticoagulation clinic -A telehealth model to deliver anticoagulation care during COVID-19 pandemic: Does it work? (Preprint)
Authors: S SunilKumar , Gona Oliver Joel , Desai Nagaraj , Shetty Shyam Prasad , B Madhu , M Ramesh
Published: July 2020

BACKGROUND

COVID -19 pandemic is a disaster. Nationwide lockdown imposed during this pandemic rendered healthcare inaccessible to several patients. Telehealth is a potential alternative utilizing a virtual platform to deliver health care. Patients taking Vitamin K antagonists (VKAs) need continuity of care to achieve and maintain optimal anticoagulation. Moreover, significant numbers of patients taking VKAs have multiple comorbidities making them susceptible to severe COVID-19 infection. Virtual anticoagulation clinic (VAC) was launched to ensure uninterrupted care with reduced exposure of these patients to COVID-19.

OBJECTIVE

We aimed to study the impact of newly launched Virtual anticoagulation clinic on the quality of anticoagulation and patient satisfaction.

METHODS

Prospective observational study was conducted on patients enrolled in to the VAC. Out of 356 patients receiving dedicated Anticoagulation clinic care at JSS Hospital, Mysore 128 patients consented to receive anticoagulation care virtually. Digital platforms like WhatsApp, email and voice call/ SMS were used. Patients were monitored for anticoagulation related parameters like TTR, PINRR and adverse events. Patient satisfaction questionnaire (5-point Likert scale) was administered at the end of 3 months.

RESULTS

Mean age was 55.62 ± 13.77 years with 57% men. Hypertension (55.5%) and diabetes (38.3%) were the most common comorbidities. Atrial fibrillation (61%) was the most common indication. Mean TTR was 75.4± 8.9 %. PINRR was 66.7± 9.47%. 1.8% of INRs were in extreme range. WhatsApp (73%), email (19%) was the most common digital platform used. Voice call and SMS was used by 8% of patients. 74% were extremely satisfied with overall VAC care and 82% of patients were extremely satisfied to continue virtual care as assessed by 5-point Likert scale questionnaire.

CONCLUSIONS

During the current COVID pandemic, Virtual anticoagulation clinic through digital technology platform was able to provide a satisfactory care to the patients who were on chronic VKA therapy over a short term.

Remote Monitoring of the Performance Status and Burden of Symptoms of Patients With Gastrointestinal Cancer Via a Consumer-Based Activity Tracker: Quantitative Cohort Study (Preprint)
Authors: Ghods Alireza , Shahrokni Armin , Ghasemzadeh Hassan , Cook Diane
Published: July 2020

BACKGROUND

The number of older patients with gastrointestinal cancer is increasing due to an aging global population. Minimizing reliance on an in-clinic patient performance status test to determine a patient’s prognosis and course of treatment can improve resource utilization. Further, current performance status measurements cannot capture patients' constant changes. These measurements also rely on self-reports, which are subjective and subject to bias. Real-time monitoring of patients' activities may allow for a more accurate assessment of patients’ performance status while minimizing resource utilization.

OBJECTIVE

This study investigates the validity of consumer-based activity trackers for monitoring the performance status of patients with gastrointestinal cancer.

METHODS

A total of 27 consenting patients (63% male, median age 58 years) wore a consumer-based activity tracker 7 days before chemotherapy and 14 days after receiving their first treatment. The provider assessed patients using the Eastern Cooperative Oncology Group Performance Status (ECOG-PS) scale and Memorial Symptom Assessment Scale-Short Form (MSAS-SF) before and after chemotherapy visits. The statistical correlations between ECOG-PS and MSAS-SF scores and patients’ daily step counts were assessed.

RESULTS

The daily step counts yielded the highest correlation with the patients' ECOG-PS scores after chemotherapy (P<.001). The patients with higher ECOG-PS scores experienced a higher fluctuation in their step counts. The patients who walked more prechemotherapy (mean 6071 steps per day) and postchemotherapy (mean 5930 steps per day) had a lower MSAS-SF score (lower burden of symptoms) compared to patients who walked less prechemotherapy (mean 5205 steps per day) and postchemotherapy (mean 4437 steps per day).

CONCLUSIONS

This study demonstrates the feasibility of using inexpensive, consumer-based activity trackers for the remote monitoring of performance status in the gastrointestinal cancer population. The findings need to be validated in a larger population for generalizability.
Older Adult Peer Support Specialists’ Age-Related Contributions to an Integrated Medical and Psychiatric Self-Management Intervention: Qualitative Study of Text Message Exchanges (Preprint)
Authors: Mbao Mbita , Collins-Pisano Caroline , Fortuna Karen
Published: July 2020

BACKGROUND

Middle-aged and older adults with mental health conditions have a high likelihood of experiencing comorbid physical health conditions, premature nursing home admissions, and early death compared with the general population of adults aged 50 years or above. An emerging workforce of peer support specialists aged 50 years or above or “older adult peer support specialists” is increasingly using technology to deliver peer support services to address both the mental health and physical health needs of middle-aged and older adults with a diagnosis of a serious mental illness.

OBJECTIVE

This exploratory qualitative study examined older adult peer support specialists’ text message exchanges with middle-aged and older adults with a diagnosis of a serious mental illness and their nonmanualized age-related contributions to a standardized integrated medical and psychiatric self-management intervention.

METHODS

Older adult peer support specialists exchanged text messages with middle-aged and older adults with a diagnosis of a serious mental illness as part of a 12-week standardized integrated medical and psychiatric self-management smartphone intervention. Text message exchanges between older adult peer support specialists (n=3) and people with serious mental illnesses (n=8) were examined (mean age 68.8 years, SD 4.9 years). A total of 356 text messages were sent between older adult peer support specialists and service users with a diagnosis of a serious mental illness. Older adult peer support specialists sent text messages to older participants’ smartphones between 8 AM and 10 PM on weekdays and weekends.

RESULTS

Five themes emerged from text message exchanges related to older adult peer support specialists’ age-related contributions to integrated self-management, including (1) using technology to simultaneously manage mental health and physical health issues; (2) realizing new coping skills in late life; (3) sharing roles as parents and grandparents; (4) wisdom; and (5) sharing lived experience of difficulties with normal age-related changes (emerging).

CONCLUSIONS

Older adult peer support specialists’ lived experience of aging successfully with a mental health challenge may offer an age-related form of peer support that may have implications for promoting successful aging in older adults with a serious mental illness.
Natural Language Processing and Machine Learning for Identifying Incident Stroke From Electronic Health Records: Algorithm Development and Validation (Preprint)
Authors: Zhao Yiqing , Fu Sunyang , Bielinski Suzette J , Decker Paul A , Chamberlain Alanna M , Roger Veronique L , Liu Hongfang , Larson Nicholas B
Published: July 2020

BACKGROUND

Stroke is an important clinical outcome in cardiovascular research. However, the ascertainment of incident stroke is typically accomplished via time-consuming manual chart abstraction. Current phenotyping efforts using electronic health records for stroke focus on case ascertainment rather than incident disease, which requires knowledge of the temporal sequence of events.

OBJECTIVE

The aim of this study was to develop a machine learning–based phenotyping algorithm for incident stroke ascertainment based on diagnosis codes, procedure codes, and clinical concepts extracted from clinical notes using natural language processing.

METHODS

The algorithm was trained and validated using an existing epidemiology cohort consisting of 4914 patients with atrial fibrillation (AF) with manually curated incident stroke events. Various combinations of feature sets and machine learning classifiers were compared. Using a heuristic rule based on the composition of concepts and codes, we further detected the stroke subtype (ischemic stroke/transient ischemic attack or hemorrhagic stroke) of each identified stroke. The algorithm was further validated using a cohort (n=150) stratified sampled from a population in Olmsted County, Minnesota (N=74,314).

RESULTS

Among the 4914 patients with AF, 740 had validated incident stroke events. The best-performing stroke phenotyping algorithm used clinical concepts, diagnosis codes, and procedure codes as features in a random forest classifier. Among patients with stroke codes in the general population sample, the best-performing model achieved a positive predictive value of 86% (43/50; 95% CI 0.74-0.93) and a negative predictive value of 96% (96/100). For subtype identification, we achieved an accuracy of 83% in the AF cohort and 80% in the general population sample.

CONCLUSIONS

We developed and validated a machine learning–based algorithm that performed well for identifying incident stroke and for determining type of stroke. The algorithm also performed well on a sample from a general population, further demonstrating its generalizability and potential for adoption by other institutions.
Co’FeeL: An Insightful COVID’19 Emotion Analysis based on Worldwide Twitter Data and Advanced Deep Learning Techniques (Preprint)
Authors: Patil Shruti , Matta Nikhil , Kotecha Dr.Ketan
Published: July 2020

UNSTRUCTURED

The coronavirus outbreak has altered the complete living pattern of human beings across the globe. It has disrupted the way we live, work, and play. The preventive norm of social distancing has created a void in our society’s social fabric. It has affected us not only physically or financially but has created a greater impact on our emotional wellbeing as well. This distress in our emotional quotient is a result of multiple factors such as financial implications, family member’s behavior, and support, country-specific lockdown protocols, media influence, fear of a pandemic, etc. For efficient pandemic management, there is an urgent need to understand these emotional variations among the masses, as they would provide great insights regarding the public sentiments towards the government pandemic management policies. It will also bring to light the weaker emotional sections of the masses, which we should be strengthening to face further situations more effectively. During this time, more and more people have used various social media platforms such as Twitter to stay connected and express their feelings and concerns. In this paper, we have collected and analyzed over 1 million tweets of the last five months (February-June 2020) using advanced deep learning techniques such as Transfer Learning and Robustly Optimized BERT Pretraining Approach (RoBERTa) to study countrywide variations in emotions. We have categorized emotions into eight classes viz. anger, depression, enthusiasm, hate, relief, sadness, surprise, and worry. The outcome of this analysis, which is represented in the form of graphs, provides insights into how emotions have changed over time for various countries. These insights can be very useful not only in formulating effective pandemic management strategies but also to devise predictive strategies for the emotional wellbeing of the country as a whole and citizens in particular for future distress events.

Na segunda apresentaremos algumas alternativas teórico-metodológicas no escopo de uma parte dessas pesquisas e, entre elas, o percurso do projeto “Narrativa Histórica nos livros didáticos: tradição e rupturas.”
Avaliação da aprendizagem no Ensino de História: entre “silêncios de” e “desafios para” um campo de pesquisa
Authors: Martins Marcus Leonardo Bomfim
Published: July 2020

Este artigo parte do pressuposto que o Ensino de História consolida-se na contemporaneidade como campo específico de produção de conhecimento sobre os múltiplos processos relacionados ao ensino escolar da História. A proposta deste texto é, pois, explorar um desses processos: a avaliação da aprendizagem. Nesse sentido, o objetivo é sumariar se e como a avaliação das aprendizagens históricas tem sido problematizada nesse campo. Ao pesquisar no Banco da Capes e os anais da ANPUH, do Perspectivas EH e do ENPEH, constata-se que apesar do caráter incontornável da avaliação nos processos escolares, no campo do Ensino de História essa discussão não tem assumido lugar de relevância.
“Relatos de intolerância e ritos de violência”: as representações dos conflitos entre protestantes e católicos na imprensa de Alagoas e Pernambuco (1873 - 1910)
Authors: Gomes César Leandro Santos
Published: July 2020

O artigo tem o objetivo de apresentar as reflexões preliminares de uma pesquisa futura, com a finalidade de analisar os conflitos entre protestantes e católicos, nos jornais de Alagoas e Pernambuco, entre os anos de 1874 a 1923. Na conjuntura em questão, a imprensa brasileira se consolidou como veículo de circulação de ideias, constituindo-se como uma ferramenta importante para a observação de tensões nos âmbitos políticos, sociais e religiosos. Logo, pretende-se observar nos relatos dos jornais da época a forma como são representadas as tensões entre estes dois grupos religiosos. As considerações de Natalie Zemon Davis acerca dos ritos de violência (1990, p. 134) e de Pierre Bourdieu a respeito da violência simbólica (2004, p.106), contribuíram para compreender a problemática a ser estudada.Palavras-chaves: História das religiões, conflitos religiosos, Jornais

Authors: Diniz Leandro Neves
Published: July 2020

Os anos de 1850 – 1870 presenciaram uma série de transformações no cenário econômico da Paraíba. Visando implementar a agropecuária, os presidentes de província legislaram negligenciando a população de livres e pobres. Este artigo tem por objetivo analisar como a força da mão de obra de homens, mulheres, e famílias de livres e pobres, impreciso grupo social, moveu a economia interna e externa da Paraíba no século XIX. Eram pessoas que estavam à margem da ordem escravista vigente, não eram escravizados e nem tão pouco possuidores de grandes posses. Demonstraremos como algumas medidas de modernização da lavoura afetaram diretamente essa população alvo de nossa pesquisa, como também os resultados efetivos na economia paraibana.

Association Between Fasting Glucose Variability in Young Adulthood and the Progression of Coronary Artery Calcification in Middle Age
Authors: Feng Weijing , Li Zhibin , Guo Wenjie , Fan Xianglin , Zhou Feiran , Zhang Kun , Ou Caiwen , Huang Feifei , Chen Minsheng
Published: July 2020

OBJECTIVE

To
investigate whether intraindividual variability of fasting glucose (FG) in
young adulthood is associated with coronary artery calcification (CAC)
progression in middle age.

RESEARCH DESIGN
AND METHODS

We
included 2,256 CARDIA (Coronary Artery Risk Development Study in Young
Adults) participants with CAC assessment by computed tomography scanner
at baseline (2000–2001) and 10 years later (2010-2011). CAC progression was assessed
for each individual as the difference of logarithmic CAC scores at follow-up
and baseline (log [CAC (follow-up) + 1] - log [CAC (baseline) + 1]). FG
variability was defined by the coefficient of variation about the mean FG
(FG-CV), the SD of FG (FG-SD), and the average real variability of FG (FG-ARV) during
10-year follow-up. We investigated the association between FG variability and
CAC progression with adjustment for demographics, clinical risk factors, mean
FG level, change in FG level, diabetes incidence and medication use.

RESULTS

After
multivariable adjustment, 1-SD increment in FG-CV was associated with worse progression
of CAC as demonstrated as percent change in CAC with 5.9% (incident CAC, 95% CI
1.0%, 10.7%) and 6.7% (any CAC progression, 95% CI 2.3%, 11.1%) progression during
10 years. Similar findings were also observed in FG-SD and FG-ARV.

CONCLUSIONS

Higher
FG variability during young adulthood was associated with greater CAC
progression in middle age, suggesting its value in predicting risk for
subclinical coronary artery diseases.

Published: July 2020

In recent years, thermal control systems performance has improved in numerous ways due to developments in control theory and information technology. Efforts have been made to produce more efficient heat exchangers by employing various methods of heat transfer enhancement.  An increase in heat exchanger performance can lead to a more economical design of heat exchanger which can help to make energy, material & cost savings related to a heat exchange process. Compact heat exchangers (CHEs) technologies are expected to be one of the solutions for the new generation heat exchanger.  In this paper are presented of the compact heat exchanger, Plate-fin heat exchanger, and Printed Circuit Heat Exchanger. And computation fluid dynamic is used which offers an alternative to the quick and inexpensive solution for the design and optimization of compact heat exchangers.

Deployment of mini macrocell base stations can also be referred to as femtocells improve quality of service of indoor and outdoor users. Nevertheless, mobility management remains a key issue with regards to their deployment. This paper is leaned towards this issue, with in-depth focus on the most important aspect of mobility management - handover. In handover management, making a handover decision in the LTE two-tier macrocell femtocell network is a crucial research area. Decision algorithms in this research, are classified and comparatively analyzed according to received signal strength, user equipment speed, cost function and interference. However, it was observed that most of the discussed decision algorithms fail to consider cell selection with hybrid access policy in a single macrocell multiple femtocell scenario, another observation was a majority of these algorithms lack the incorporation of user equipment residence parameter. Not including this parameter boosts the number of unnecessary handover occurrence. To deal with these issues, a sophisticated handover decision algorithm is proposed. The proposed algorithm considers the user’s velocity, received signal strength, residence time as well as the femtocell base station’s access policy. Simulation results have shown that the proposed algorithm reduces the number of unnecessary handovers when compared to conventional received signal strength based handover decision algorithm.

Pairwise testing is an approach that tests every possible combinations of values of parameters. In this approach, number of all combinations are selected to ensure all possible pairs of parameter values are included in the final test suite. Generating test cases is the most active research area in pairwise testing, but the generation process of the efficient test suite with minimum size can be considered as one of optimization problem. In this research paper we articulate the problem of finding a pairwise final test suite as a search problem and the application of harmony search algorithm to solve it. Also, in this research paper, we developed a pairwise software testing tool called PWiseHA that will generate test cases using harmony search algorithm and this PWiseHA is well optimized. Finally, the result obtained from PWiseHA shows a competitive results if matched with the result of existing pairwise testing tools. PWiseHA is still in prototype form, an obvious starting point for future work.
Adaptive Inverse Neural Network Based DC Motor Speed and Position Control Using FPGA
Authors: N. Abd Aula
Published: July 2020

In this research two types of controllers are designed in order to control the speed and position of DC motor. The first one is a conventional PID controller and the other is an intelligent Neural Network (NN) controller that generate a control signal DC motor. Due to nonlinear parameters and movable laborers such saturation and change in load a conventional PID controller is not efficient in such application; therefore neural controller is proposed in order to decreasing the effect of these parameter and improve system performance. The proposed intelligent NN controller is adaptive inverse neural network controller designed and implemented on Field Programmable Gate Array (FPGA) board. This NN is trained by Levenberg-Marquardt back propagation algorithm. After implementation on FPGA, the response appear completely the same as simulation response before implementation that mean the controller based on FPGA is very nigh to software designed controller. The controllers designed by both m-file and Simulink in MATLAB R2012a version 7.14.0.

Published: July 2020

The island of Borneo has faced seasonal forest fires for decades. This phenomenon is worsening during dry seasons, especially when droughts are concurrent with the El Niño-Southern Oscillation (ENSO) phenomenon. Climate is therefore one of the drivers of the fire phenomenon. This paper studies the relationship between climate variables, namely temperature, precipitation, relative humidity, and wind speed, and the occurrence of forest fire using two clustering methods, K-means and Fuzzy C-means (FCM) clustering methods. Borneo is clustered into four areas based on burned area data obtained from Global Fire Emission Data (GFED). It is also clustered according to the combinations of climate variables. Both methods reach the highest correlation between the climate variable and the burned area clusters in September. The K-means method gives a correlation of -0.54 while the FCM gives -0.55. In August until October, relative humidity provides the dominant correlation affecting burned area, even though an additional precipitation or wind variable slightly increases the correlation in the FCM method. In November, temperature largely contributed to the burned area by a positive correlation of 0.31 in K-means and 0.33 in FCM. The evaluation performance of the methods is conducted by an internal validation called the Silhouette index. Both methods have positive index values ranging from 0.39 to 0.69 and the maximum value is influenced by the wind cluster. This indicates that the clustering methods applied in this paper can identify one or a combination of climate variables into dense and well-separated clusters.

Aims

The main cause of atrial fibrillation recurrence after catheter ablation is pulmonary vein reconnection. The purpose of this retrospective study was to analyse the electophysiological findings in patients undergoing repeat procedures after an index cryoballoon ablation (CB-A) and presenting with permanency of pulmonary vein isolation (PVI) in all veins. In addition, we sought to compare the latter with a similar group of patients with reconnected veins at the redo procedure.

Methods

A total of 132 patients (81 men, 60.7 ± 12.4 years) who underwent CB-A for paroxysmal atrial fibrillation (PAF) were enrolled. Indication for the redo procedure was symptomatic PAF in 83 (63%), persistent atrial fibrillation (PerAF) in 32 (24%) or persistent regular atrial tachycardia (RAT) in 17 (13%) patients.

Results

Seventy-five (57%) patients presented a pulmonary vein reconnection (pulmonary vein group) during the redo procedure, whereas 57 (43%) had no pulmonary vein reconnection (non-pulmonary vein group). The non-pulmonary vein group exhibited significantly more non-pulmonary vein foci and atrial flutters than the pulmonary vein group after induction protocol (51 vs. 24%,P = 0.002 and 67 vs. 36%,P = 0.003, respectively). Twenty-two (29.3%) patients of the pulmonary vein group and 20 (35%) patients of the non-pulmonary vein group had atrial fibrillation/RAT recurrence after a mean follow-up of 12.5 ± 8 months. The survival analysis demonstrated no statistical significance in recurrence between both groups (log rankP = 0.358).

Conclusion

Atrial fibrillation/RAT recurrence in patients after CB-A with durable PVI is significantly associated with non-pulmonary vein foci and atrial flutters. No statistically different success rate regarding atrial fibrillation/RAT freedom was detected between the pulmonary vein and non-pulmonary vein groups after redoing RF-CA.

Authors: Marković Nikola
Published: July 2020

Ovim radom se primarno želi oprav­dati sve veća upotreba montažnih grednih betonskih mostova danas sa aspekta ekonomičnosti i racionalnosti, njihova sve veća konkurentnost na tržištu i verovatno potiskivanje tradicionalnog načina građenja u budućnosti. Kroz primere ćemo proći kroz sve metode i tehnologije izgradnje ovih mostova. Ovaj rad će se bazirati na primeni montažnih elemenata koji su iste dužine kao u eksploataciji. Treba napomenuti da prefabrikovani elementi mogu biti i manje dužine od elemenata u eksploataciji što rezultuje nekim drugim metodama izgradnje.
