Authors: Hosseini-Ghalibaf Seyyede-Nadia , Ranjbar Akram , Yasrebifar Fatemeh , Mirzaei Ehsan , Mirjalili Mahtabalsadat , Mohammadi Younes , Mehrpooya Maryam
Published: March 2020

Background:

Although depression is the predominant phase in Bipolar Disorder (BPD)
and causes the most psychosocial disability, optimal pharmacotherapy of bipolar depression is not
known yet. Advances in research on BPD neurobiology have demonstrated that oxidative toxic
stress (OTS) may be involved in the pathophysiology of BPD.

Objective:

The present study aimed to evaluate the effects of adjuvant CoQ10, supplement with potent
antioxidant properties, on salivary and urinary OTS biomarkers in patients with BPD during the
depressive episode.

Material and Methods:

89 BPD patients with current depressive episode were allocated into either
CoQ10 (200 mg/day) or placebo group by block randomization method. The salivary and urinary
levels of OTS biomarkers including Total Antioxidant Capacity (TAC) and DNA damage were
measured at baseline and 8 weeks after treatment.

Results:

At baseline, urinary and salivary levels of TAC and DNA damage were statistically comparable
between the two groups. After 8 weeks treatment with CoQ10, patients showed significantly
higher increment in urinary TAC level compared to placebo, while salivary level of TAC did not
display significant differences between the two groups. Although changes in salivary and urinary
DNA damage levels were greater in CoQ10 group, the changes reached significant level only in the
urine sample.

Conclusion:

Our findings suggest that CoQ10 can improve OTS status in BPD patients during depressive
episode. As activation of oxidative stress is one of the mechanisms responsible for BPD, it
seems that CoQ10 due to its proven antioxidant properties, as add on therapy to standard treatment
may be a promising agent in treating bipolar depression.

Authors: Deshmukh Lalita D. , Chavan Kalyan B.
Published: March 2020

Objective:

Herein, we report zinc oxide (ZnO) nanoparticles (NPs) synthesized by a
simple precipitation method using zinc acetate dihydrate (Zn(CH3CO2)2. 2H2O) and sodium hydroxide
(NaOH) precursors in aqueous media.

Method:

Synthesized material was annealed at different temperatures to check phase formation
and its purity.

Results:

At room temperature, the sample shows the formation of zinc hydroxide and at high temperature
(100, 200, and 300°C) shows the formation of ZnO. Synthesized materials were analyzed
by different techniques. X-ray diffraction analysis shows the formation of a hexagonal crystal
structure. Morphological features were analyzed by the SEM technique which shows agglomerated
nanoparticles.

Conclusion:

The optical properties of ZnO were studied by using UV analysis and showed intrinsic
excitonic transition property of the ZnO semiconductor. Further, with an increase in annealing
temperature crystalline size, agglomeration of nanoparticles found to be increased whereas the
bandgap decreased.
A Study of Metabolic Syndrome in Patients on Risperidone
Authors: Thangraj Ajay , Desai Nimesh G. , Singh Vijender
Published: March 2020

Background:

Novel antipsychotics are superior to conventional antipsychotics,
as they significantly reduce both positive and negative symptoms of schizophrenia and
have lower risk of extra pyramidal syndrome (EPS). However, these drugs cause significant
metabolic side effects.

Objective:

This study was carried out to assess the hospital prevalence of metabolic syndrome
(MetS) and metabolic profile related to use of oral risperidone which is one of the
most commonly used atypical antipsychotics.

Methods:

A cross-sectional study was carried out on a period sample of 6 months, to study
the hospital prevalence and profile of MetS in adult patients on oral risperidone. Data was
collected from pharmacy dispensing records, patients’ case record files, and subsequently
patients were contacted telephonically and called to participate in this study.

Results:

Hospital prevalence of MetS was found to be 12.1% (13 out of 107) by NCEP
ATP III criteria and 14.9% (16 out of 107) by IDF criteria in patients (aged 20 to 40 years)
on risperidone. Ninety one patients (85%) of the sample were found to be in Overweight
category and Central Obesity was found in 82(76.6%) patients. Twenty three (21.4%) of
the patients had increased triglyceride (TG) levels. Out of the 16 patients with MetS,
11(68.75%) of them had total duration of illness (TDI) of >4 years, 11(68.75%) were in
30-40 years age group, 13 (81.25%) of them had continued illness or they were in partial
remission, 11 (68.75%) of them were already exposed to any antipsychotics other than
risperidone, 6(37.5%) of them were having diabetes mellitus (DM) in one parents.

Conclusion:

This study reported the hospital prevalence of MetS as 14.9% (IDF criteria) in
young adult patients on oral risperidone. The triglyceride levels and central obesity was also
found to be higher in patients, who otherwise had low prevalence of MetS.

Whole Grains, Dietary Fibers and the Human Gut Microbiota: A Systematic Review of Existing Literature
Authors: Tangestani Hadith , Emamat Hadi , Ghalandari Hamid , Shab-Bidar Sakineh
Published: March 2020

Background:

The health benefits of dietary fibers have been proved for a long time. The
importance of microbiota has been identified in human health and there is a growing interest to
study the factors affecting it.

Objective:

This systematic review aimed to investigate the impact of fiber and whole grains (WGs)
on human gut microbiota in a patent-based review.

Methods:

All related clinical trials were systematically searched on PubMed and Scopus search engines
from inception up to Feb 2020. Interventional human studies reporting changes in microbiota
by using any type of grains/fibers were included. The following information was extracted: date of
the publication, location and design of the study, sample size, study population, demographic characteristics,
the amount of dietary WGs/fiber, the duration of intervention, the types of grains or fibers,
and changes in the composition of the microbiota.

Results:

Of 138 studies which were verified, 35 studies with an overall population of 1080 participants,
met the inclusion criteria and entered the systematic review. The results of interventional trials
included in this review suggest some beneficial effects of consuming different amounts and
types of WGs and fibers on the composition of intestinal microbiota. Most included studies showed
that the intake of WGs and fibers increases bifidobacteria and lactobacilli and reduces the pathogenic
bacteria, such as Escherichia coli and clostridia in the human gut.

Conclusion:

The consumption of WGs/fibers may modify the intestinal microbiota and promote
the growth of bifidobacteria and lactobacilli. Nevertheless, further research is warranted in different
populations and pathological conditions.
Visual Target Tracking via Online Reliability Evaluation and Feature Selection in the Framework of Correlation Filtering
Authors: Wei Li , Ding Meng , Cao Yun-Feng , Zhang Xu
Published: March 2020

Background:

Although correlation filtering is one of the most successful visual tracking
frameworks, it is prone to drift caused by several factors such as occlusion, deformation and
rotation.

Objective:

In order to improve the performance of correlation filter-based trackers, this paper proposes
a visual tracking method via online reliability evaluation and feature selection.

Methods:

The main contribution of this paper is to introduce three schemes in the framework of correlation
filtering. Firstly, we present an online reliability evaluation to assess the current tracking
result by using the method of adaptive threshold segmentation of response map. Secondly, the proposed
tracker updates the regression model of correlation filter according to the assessment result.
Thirdly, when the tracking result based on a handcrafted feature is not reliable enough, we propose a
feature selection scheme that autonomously replaces a handcrafted feature used in the traditional
correlation filter-based trackers with a deep convolutional feature that can re-capture the target by its
powerful discriminant ability.

Results:

On OTB-2013datasets, the Precision rate and Success rate of the proposed tracking algorithm
can reach 84.8% and 62.5%, respectively. Moreover, the tracking speed of proposed algorithm
is 19 frame per second.

Conclusion:

The quantitative and qualitative experimental results both demonstrate that the proposed
algorithm performed favorably against nine state-of-the-art algorithms.
Ailing Apps: An Analysis of Protected Health Information Leakage in Medical Smartphone Applications (Preprint)
Authors: Grispos George , Flynn Talon , Glisson William Bradley
Published: March 2020

BACKGROUND

An emerging trend is the development of smartphone applications, which act as an interface to medical devices connected to the Internet. Many of these devices, along with their smartphone applications, have been approved by the United States Food and Drug Administration (FDA) for use in medical settings. Furthermore, device manufacturers are expected to comply with the Health Insurance Portability and Accountability Act (HIPAA) of 1996. As a result, manufacturers are required to implement safeguards to protect a patient’s personal and medical information.

OBJECTIVE

Previous research has shown that smartphone applications produce residual data, which can have security and privacy implications. Hence, there is the potential that the residual data generated by smartphone applications that interact with medical devices is potentially putting patient information at risk. This study investigates residual data recovered from a smartphone application, which interacts with a medical device, from the perspective of Security and Privacy violations within HIPAA.

METHODS

This study includes a controlled experiment to investigate the residual data generated by Android and iOS smartphone applications that accompany seven FDA-approved medical devices. The devices and their smartphone applications were used for five days in a test environment. The smartphone applications were then processed using industry-accepted mobile forensic toolkits to retrieve resident residual artifacts. Once the processing was complete, the data extractions were analyzed for patient information as well as medical device interactions.

RESULTS

The analysis of the Android and iOS smartphone applications revealed that data related to the test patient, and their use of the medical device could be retrieved from three out of the four applications. These three applications store patient and device data in plaintext, including passwords. However, analysis of the fourth application evaluated in this experiment has shown that while the iOS version stores information in plaintext, the Android version appears to encrypt artifacts containing patient and therapy details.

CONCLUSIONS

While all the medical devices included in the controlled experiment are cleared by the FDA, and all the manufacturers claim to be HIPPA compliant; the devices and applications used in this study demonstrate that it is possible to recover plaintext patient-specific and device information from the smartphone applications that interface with these devices.

Published: March 2020

BACKGROUND

Cognitive behavioral therapy (CBT) is recommended in guidelines for people with refractory irritable bowel syndrome (IBS). However, the availability of CBT is limited, and poor adherence has been reported in face-to-face CBT.

OBJECTIVE

Nested within a randomized controlled trial of telephone- and web-delivered CBT for refractory IBS, this qualitative study aims to identify barriers to and facilitators of engagement over time with the interventions, identify social and psychological processes of change, and provide insight into trial results.

METHODS

A longitudinal qualitative study was nested in a randomized controlled trial. Repeated semistructured interviews were conducted at 3 (n=34) and 12 months (n=25) post baseline. Participants received telephone-based CBT (TCBT; n=17 at 3 months and n=13 at 12 months) or web-based CBT (WCBT; n=17 at 3 months and n=12 at 12 months). Inductive thematic analysis was used to analyze the data.

RESULTS

Participants viewed CBT as credible for IBS, perceived their therapists as knowledgeable and supportive, and liked the flexibility of web-based and telephone-based delivery; these factors facilitated engagement. Potential barriers to engagement in both groups (mostly overcome by our participants) included initial skepticism and concerns about the biopsychosocial nature of CBT, initial concerns about telephone-delivered talking therapy, challenges of maintaining motivation and self-discipline given already busy lives, and finding nothing new in the WCBT (WCBT group only). Participants described helpful changes in their understanding of IBS, attitudes toward IBS, ability to recognize IBS patterns, and IBS-related behaviors. Consistent with the trial results, participants described lasting positive effects on their symptoms, work, and social lives. Reasons and remedies for some attenuation of effects were identified.

CONCLUSIONS

Both TCBT and WCBT for IBS were positively received and had lasting positive impacts on participants’ understanding of IBS, IBS-related behaviors, symptoms, and quality of life. These forms of CBT may broaden access to CBT for IBS.

Published: March 2020

India is the only country in the world running two different doctoral courses for doctors, i.e., Doctor of Medicine (MD) and Diplomate of National Board (DNB). DNB course was introduced in 1975 to overcome shortage of specialist doctors and medical teachers. Both courses have centralized entry examination, similar tenure period, academic and clinical activities, and research exposure and exit examination (in the host institute in MD examination and in designated exit exam centre in institute other than poarent institute in case of DNB examination). Initially, the Ministry of Health and Family Welfare and Medical Council of India (MCI) established the equivalence between two. Discrimination started since October 2012 through MCI gazette notification for DNB trainees from non-MCI recognized institutes with regards to teacher appointment. DNB doctors were united to raise their voice against this. While the Government of India (GOI) is in favor of equivalence between two, MCI is against the same. Recently, MCI is dissolved and is going to be replaced by the National Medical Commission and positive outcome is expected for the DNB side. A recent notification is issued toward equivalence of two courses provided candidate completed DNB course from hospitals with minimum 500 beds. Evaluating quality of education on the basis of number of beds seems unjustifiable as there are many better indicators of quality of medical education. The NMC act also retained the same 500 bed criteria. Taking into account the view point of benefit of population and improvement in medical education in India, it is desirable to reconsider the issue by the Government of India (GOI) and to act accordingly. To enhance the standard of current medical education, higher standards should be imposed in curriculum and centralized exit examination to be made compulsory for both the courses.

Authors: PHILIPS NATHALA JOHN MANI , S SHIVASHREE , M SAHYADRI , SN MANJULA , PARIHAR VIPAN K
Published: March 2020

Cancer is the third leading cause of death worldwide. The current cancer treatments such as chemotherapy and radiotherapy resulting in the development of unintended adverse effects that reduce the quality of life and economic burden in oncology patients. Nutraceuticals along with food value have natural bioactive components that have reassuring therapeutic properties in several diseases. Herbs of significant interest have been proven to prevent and treat various types of cancer and also reduce the side effects of chemotherapy and radiotherapy. The efficacy of nutraceuticals and herbs such as chemopreventive and chemotherapy is highlighted. We conclude that further studies are required to countersign the targeted approaches and efficacy of herbs and nutraceuticals in cancer patients as adjuvant therapy.

Objectives: The serum zinc and platelet statuses of sickle cell patients attending General Hospital, Owerri, Nigeria, were investigated.

Methods: Fifty confirmed sickle cell patients (hemoglobin [Hb]SS) age 10–30 years were selected. Fifty normal subjects (HbAA) age 10–30 years were used as control. The zinc and platelets were determined using standard methods.

Results: The levels of serum zinc, selenium, and platelet were significantly decreased in sickle cell anemia (p<0.05) when compared with the control.

Conclusion: The result suggests that supplementation of sickle cell patients with food and drug-containing zinc might be helpful, particularly in wound healing, as zinc positively correlates with platelet counts. These low zinc, selenium, and platelets could represent a risk for sickle cell anemia.

MASCULINIDADES NEGRAS EM MOVIMENTO – O CINEMA NEGRO COMO PRÁTICA DECOLONIAL NA EDUCAÇÃO BLACK MASCULINITY IN MOVEMENT –THE BLACK CINEMA AS A DECOLONIAL PRACTICE IN EDUCATION
Authors: Correa Marco Aurélio Da Conceição
Published: March 2020

Este ensaio tem a proposta de dar continuidade na crescente discussão sobre as masculinidades negras, reconhecendo que estas são subjugadas como inferiores, devido as raízes coloniais racistas que criam relações assimétricas de poder, cria-se uma masculinidade hegemônica patriarcal do homem branco, hétero e cristão. Esta violência colonial aprisiona até os dias de hoje as subjetividades e as representações do homem negro. O cinema como artefato reprodutor da realidade acaba a dar sequência a estes históricos estereótipos. Porém, existe na atualidade uma emergente criação cinematográfica que busca outras representações estéticas para os corpos e mentes negras. A partir destes filmes pensamos em possibilidades pedagógicas que descolonizem as mentes e ressignifiquem as masculinidades negras. This text has the proposal to continue the growing discussion about black masculinities, recognizing that those are subjugated as inferior because of the racist colonial roots that create asymmetrical relations of power creating the patriarchal hegemonic masculinity of the white, straight and Christian man. This colonial violence imprisons until the present day the subjectivities and representations of the black man. Cinema as a reproductive artifact of reality ends up following these historical stereotypes. However, nowadays there is an emerging cinematic creation that seeks other aesthetic representations for black bodies and minds. From these films we think of pedagogical possibilities that decolonize the minds and resignify the black masculinities.

Este artigo discute a universalização das bibliotecas escolares de municípios do Estado do Rio de Janeiro, tendo em vista a Lei 12.244 que determina esta universalização até 2020, e apresenta reflexões sobre o profissional que nelas atuam e suas funções. Trata-se da análise de parte das respostas de um questionário distribuídos às 92 secretarias municipais de educação do estado que obteve 67% de retorno. A pesquisaevidencia que os municípios ainda não universalizaram as bibliotecas nas escolas, especialmente na Educação Infantil, e que pouco mais da metade já colocou este tema em pauta. Mostra também poucas reflexões sobre o profissional que atua nas bibliotecas escolares. No entanto, a maioria das respostas consideram que das funções atribuídas a ele incluem a organização do espaço, o tratamento do acervo e ações mediadoras da leitura. This article discusses the universalization of the school libraries of municipalities of the state of Rio de Janeiro, in view of law 12.244 that determines this universalization until2020, and presents reflections on the professionals who work in them and their functions. It is the analysis of part of the answers of a questionnaire distributed to the92 municipal secretaries of education of the state that obtained 67% of return. The research shows that municipalities have not yet universalized libraries in schools,especially in early childhood education, and that little more than half has already put this topic in the agenda. It also shows few reflections about the professional who works in school libraries. However, most of the answers consider that the functions assigned to him include the organization of space, the treatment of the collection and mediating actions of reading.

Starting from the premise that life is constitutively precariousand from the fact that education can be crucial to the persistence of our lives, we will try to find out the possible partnerships between education, recognition and production of knowledge, tracing its limits and potentialities and ambiguities.
TRAVESSIAS AO ENCONTRO COM UMA ÉTICA/ESTÉTICA NA EDUCAÇÃO
Authors: Silva Dagmar Mello e , Barbatho Goulart Paula
Published: March 2020

Consideramos esse ensaio uma transgressão e uma licença poética que surge de uma aporia em relação a forma da escrita acadêmica. Transgressão, por estar submetido a uma seção da revista destinada a autores outorgados por seus títulos e que ora abre uma brecha - licença poética - para publicar a escrita de uma travessia em que professora e aluna atravessam de mãos dadas, o rito de passagem (conclusão do trabalho de curso de Pedagogia) que deu a pensar essa tessitura que se inspira em uma produção fílmica – Capitão Fantástico – para tratar de aspectos éticos/estéticos de uma educação com olhos de poeta.
RESISTÊNCIA E AUTONOMIA NA EDUCAÇÃO INFANTIL
Authors: FURLIN BAMPI MARIA LUISA , Schindhelm Virgínia Georg
Published: March 2020

O grito/desabafo da criança, que disparou este artigo, parte de um embate cotidiano observado numa escola de educação infantil e apresenta reflexões sobre experiências de crianças e as relações intersubjetivas representadas por figuras de autoridade, por condutas de indisciplina e por construções de autonomia moral no cotidiano escolar. O texto dialoga com os temas indisciplina, autoridade, autonomia e resistência, numa relação ensino/aprendizagem onde a experiência vivenciada e os sentidos construídos norteiam as pedagogias do dia-a-dia no cenário da educação infantil. Compreende-se a escola como um potencial de acesso aos conteúdos científicos, às experiências desafiadoras capazes de transformar e desencadear processos de desenvolvimento e comportamentos nas crianças e também nas educadoras.
INCLUSÃO EM EDUCAÇÃO NA PERSPECTIVA DO DESENHO UNIVERSAL PARA APRENDIZAGEM COMO INSTRUMENTO DE DESENVOLVIMENTO E EMANCIPAÇÃO PARA ESTUDANTES COM DEFICIÊNCIA INTELECTUAL
Authors: De Souza Marisa Mendes Machado , Gomes Suzete Araujo Oliveira
Published: March 2020

Embora o país tenha conseguido ver de perto a universalização do acesso à escola, não conseguiu o mesmo com o conhecimento, incluindo o desenvolvimento acadêmico de estudantes com deficiência intelectual. Como contraponto desta realidade, o Desenho Universal para Aprendizagem ressalta essa ainda nova perspectiva de possibilidades na educação inclusiva. A partir dos conceitos e perspectivas que perpassam a inclusão em educação é destacada a relevância de um currículo planejado e exercido para a diversidade de alunos para a qual a educação se propõe. As concepções apresentadas destacam a importância de adequações pedagógicas no campo da Educação Inclusiva e correlacionam os apontamentos com a realidade escolar.

Published: March 2020

Problematizar os investimentos dogmáticos que enredam a educação e suas práticas tem sido um desafio para alguns professores. O que se poderia retirar de um programa em sala de aula que coloca a produção de imagem e de escrita como motor de uma poética formativa? Em que medida a construção imagética passa pelo corpo e suscita novos processos de subjetivação que não passe pelos fundamentos? Foram traçadas algumas zonas maquínicas a partir de um programa de experiência em uma sala de aula de um curso de formação de professores. A pesquisa será constituída por platôs de criação que atravessam o campo da estética e do poético no fazer-pensar pedagógico, através da maquinação de diferentes linguagens que dão passagem para os fluxos criativos e inventivos, arrastando vidas para a experimentação de blocos de ensinar e aprender.

Authors: Pathak Kripa Shankar , Mohan Ravindra
Published: March 2020

The potential of renewable energy should be investigated. Renewable energy is the energy from natural and unnatural available forms including wind, biomass, solar, and waste heat energy generated through various human activities. Solar energy is an available and clean form of renewable energy used as an alternative to fossil fuel in generating energy. However, the maximum extraction of thermal energy from the sun is most challenging. This study focuses on energy generation using the parabolic trough collector (PTC). This review contains geometrical analysis including the thermal approach of the PTC model, heat transfer, and method of enhancing thermal efficiency on the PTC receiver. So to identify the performance analysis, thermal efficiency, and applications of the solar-powered PTC and the history of PTC evolution. The PTC applications include desalination process, air heating system, power plants, refrigeration, and industrial heating purposes.
Evaluation of variables associated with outcomes in 41 dogs with incompletely excised high-grade soft tissue sarcomas treated with definitive-intent radiation therapy with or without chemotherapy

OBJECTIVE

To evaluate potential prognostic indicators for local recurrence, distant metastasis, and survival time in dogs with incompletely excised high-grade soft tissue sarcomas (HGSTSs), as defined by a mitotic index ≥ 9, that underwent definitive-intent radiation treatment (RT; ≥ 48 Gy total dose) with or without adjuvant chemotherapy.

ANIMALS

41 client-owned dogs with HGSTSs treated with surgical resection followed by definitive-intent RT between January 1, 2000, and December 31, 2016.

PROCEDURES

Medical records were reviewed retrospectively, and data were collected. The Kaplan-Meier method was used to evaluate the overall survival time (OST) of dogs and time to progression (TTP) of disease, starting from the first day of RT. The Cox proportional hazards model was used to analyze the impact of results for several variables on OST and TTP.

RESULTS

The median OST was 981 days, with 1-, 3-, and 5-year survival rates of 85%, 43%, and 18%, respectively. The median TTP was not reached; however, the mean TTP was 1,581 days. Ten of the 41 (24%) dogs developed metastasis, and 8 (20%) developed local recurrence. Sixteen of the 41 dogs received chemotherapy. The hazard of disease progression over the study period increased as the mitotic index (hazard ratio [HR], 1.115) or duration of RT (HR, 1.427) increased. The hazard of death over the study period increased as the RT duration (HR, 1.372) or surgical scar length (HR, 1.272) increased.

CONCLUSIONS AND CLINICAL RELEVANCE

Although adjuvant chemotherapy was not associated with improved survival time in dogs of the present study, results indicated that improved OST and TTP could be achieved through strict adherence to the prescribed irradiation schedule and avoidance of unnecessary prolongation of the course of RT.

Abstract: With nearly 3,000 large and small islands, the islands and archipelagos of Vietnam have outstanding features in terms biodiversity and geology. The islands are mainly formed from carbonate (limestone), intrusive igneous rock, sedimentary and volcanic rocks, in which limestone islands predominate, distributed mainly in the Gulf of Tonkin. This paper presents the results of researches and assessments on sea water quality of Vietnam's typical limestone islands and archipelagoes through the 2017-2018 surveys. The research results show that although the water quality around of limestone and archipelago area of Viet Nam is safety for the development of aquatic life, an increase in pollutants concentration in water has been recorded when compared to previous research results. The research results supplement the data set of sea water quality in limestone areas that defining the characteristics of marine biodiversity.
