Authors: Khalaf Reema Abu , Jarad Haya Abu , Al-Qirim Tariq , Sabbah Dima
Published: September 2020

Background:

Diabetes mellitus is a serious global health issue, currently affecting 425
million people and is set to affect over 690 million people by 2045. It is a chronic disease characterized
by hyperglycemia due to relative or absolute insulin hormone deficiency. Dipeptidyl peptidase-
IV (DPP-IV) inhibitors are hypoglycemic agents augmenting the action of the incretin hormones that
stimulate insulin secretion from the pancreatic beta cells.

Objectives:

In this study, synthesis and biological evaluation of seven piperazine derivatives 3a-g was
carried out.

Methods:

The synthesized molecules were characterized using proton-nuclear magnetic resonance,
carbon-nuclear magnetic resonance, infrared spectroscopy and mass spectrometry.

Results:

In vitro biological evaluation study showed comparable DPP-IV inhibitory activity for the
targeted compounds ranging from 19%-30% at 100 μM concentration. Furthermore, the in vivo hypoglycemic
activity of 3d was evaluated using streptozotocin-induced diabetic mice. It was found
that compound 3d significantly decreased the blood glucose level when the diabetic group treated
with 3d was compared to the control diabetic group. Quantum–Polarized Ligand Docking (QPLD)
studies demonstrate that 3a-g fit the binding site of DPP-IV enzyme and form H-bonding with the
backbones of R125, E205, E206, K554, W629, Y631, Y662, R669, and Y752.

Conclusion:

Piperazine derivatives were successfully found to be new scaffolds as potential DPP-IV
inhibitors.

Published: September 2020

Background &Aims

This study aimed to assess the changes in platelet counts of patients
with liver cirrhosis due to chronic HCV, who achieved sustained virological response (SVR)
after taking direct acting antivirals (DAAs) in a large cohort study in Egypt.

Methods:

This multicenter observational retrospective study was carried out on 2500 chronic hepatitis
C virus (HCV) infected patients who achieved (SVR) after treatment with direct acting antiviral
drugs (DAA). HCV infection was confirmed by positive PCR for HCV RNA infection. SVR
was defined as a negative PCR test for HCV-RNA 12 weeks after completion of DAA therapy.
Platelets count was measured before therapy, during therapy, at the end of treatment, and 12 weeks
after the end of the treatment.

Results:

There were 2186 patients enrolled in the study; 1866 (85.4%) were treatment naïve. There
were 1006 (46%) males and 1180 (54%) females. Mean age was 50.82± 11.66 years, 2142 (98%.0)
patients achieved SVR, 2118 (96.9%) patients had Child -Pugh class A cirrhosis, and 68 (3.1%)
had Child -Pugh class B liver cirrhosis. A significant increase in the platelets count was detected at
the end of treatment in comparison to the pretreatment levels (P<0.001), and after achieving SVR
(P<0.001) when compared to the pretreatment values.

Conclusion:

Improvement of platelets count occurs after HCV therapy with DAAS in patients with
liver cirrhosis. These results suggested that HCV eradication may have a role in the improvement
of platelet count.
Leaching of Atoms, Clusters, and Nanoparticles
Authors: Redón Rocío , García-Peña Nidia G. , Ocampo-Bravo Cristina C.
Published: September 2020

Since the elucidation of the leaching process by Mizoroki in the 1970s, the research focused
on this problem has increased. As a result, it has been discovered that the leached metals can not only
hinder product yield, but they can also remain as contaminants of the final products. Thus, it can be
concluded that metal leaching needs to be diminished or avoided more efficiently. This problem is important
for the industry and the environment because of the increases in costs and pollution. In 2014,
we reported a brief review related to this important feature; now we would like to report on the latest
findings on this important phenomenon, including an update on the mechanisms used to explain leaching
and the reactions that support those mechanisms and including patents related to leaching in catalysis
that have appeared in recent years.

Authors: Chen Liang , Zeng Zhenghao , Fu Wenbin , Hu Wenqiang , Xu Chenxi , Zhang Jiawei
Published: September 2020

:

In recent decades, carbon nanomaterials have attracted a lot of attention in the field of energy
storage and conversion due to their exceptional mechanical, electrical and chemical properties.
Nevertheless, pristine carbon nanomaterials possess inert surface and uncontrollable band gap, greatly
restricting their application. Doping heteroatoms into carbon skeleton has been verified as a valid
strategy to adjust the electronic structure and physicochemical properties of carbon nanomaterials, which
opens a new avenue to improve the electrochemical performance of carbon nanomaterials. Herein, we
first give a simple description of carbon nanomaterials and the necessity of doping heteroatoms. Then we
discuss and analyze the doping types and doping methods of heteroatoms-doped carbon nanomaterials.
Afterwards, the specific electrochemical applications of heteroatoms-doped carbon nanomaterials are
systematically introduced from the perspective of fuel cells, lithium-ion batteries, lithium-sulfur batteries
and supercapacitor. Eventually, the possible challenges in the near future for the synthesis of
heteroatoms-doped carbon nanomaterials and their related electrochemical application in the field of
energy storage and conversion are summarized.

Authors: Dinur Adva , Sherman Herbert
Published: September 2020

Outcomes Assessment (OA) has emerged as the systemic mechanism for academic institutions to demonstrate to their stakeholders their viability as institutions that create and disseminate knowledge. Properly implementing outcomes assessment plans has been of paramount concern to postsecondary academic institutions whose accrediting bodies are requiring that institutions demonstrate that they have in fact achieved their goals and objectives. This study posits a preliminary methodology (a before/after study) for using grading rubrics, an instrument developed through outcomes assessment programs, for analyzing students’ oral and written analyses of business cases. Results from the first round of data gathering from students’ oral presentations are presented.

Published: September 2020

Background

Electronic learning (e-learning) is a widely accessible, low-cost option for learning remotely in various settings that allows interaction between an instructor and a learner.

Objective

We describe the development of a free and globally accessible multilingual e-learning module that provides education material on topics in pediatric endocrinology and diabetes and that is intended for first-line physicians and health workers but also trainees or medical specialists in resource-limited countries.

Methods

As complements to concise chapters, interactive vignettes were constructed, exemplifying clinical issues and pitfalls, with specific attention to the 3 levels of medical health care in resource-limited countries. The module is part of a large e-learning portal, ESPE e-learning, which is based on ILIAS (Integriertes Lern-, Informations- und Arbeitskooperations-System), an open-source web-based learning management system. Following a review by global experts, the content was translated by native French, Spanish, Swahili, and Chinese–speaking colleagues into their respective languages using a commercial web-based translation tool (SDL Trados Studio).

Results

Preliminary data suggest that the module is well received, particularly in targeted parts of the world and that active promotion to inform target users is warranted.

Conclusions

The e-learning module is a free globally accessible multilingual up-to-date tool for use in resource-limited countries that has been utilized thus far with success. Widespread use will require dissemination of the tool on a global scale.
Intersection of the Web-Based Vaping Narrative With COVID-19: Topic Modeling Study
Authors: Janmohamed Kamila , Soale Abdul-Nasah , Forastiere Laura , Tang Weiming , Sha Yongjie , Demant Jakob , Airoldi Edoardo , Kumar Navin
Published: September 2020

Background

The COVID-19 outbreak was designated a global pandemic on March 11, 2020. The relationship between vaping and contracting COVID-19 is unclear, and information on the internet is conflicting. There is some scientific evidence that vaping cannabidiol (CBD), an active ingredient in cannabis that is obtained from the hemp plant, or other substances is associated with more severe manifestations of COVID-19. However, there is also inaccurate information that vaping can aid COVID-19 treatment, as well as expert opinion that CBD, possibly administered through vaping, can mitigate COVID-19 symptoms. Thus, it is necessary to study the spread of inaccurate information to better understand how to promote scientific knowledge and curb inaccurate information, which is critical to the health of vapers. Inaccurate information about vaping and COVID-19 may affect COVID-19 treatment outcomes.

Objective

Using structural topic modeling, we aimed to map temporal trends in the web-based vaping narrative (a large data set comprising web-based vaping chatter from several sources) to indicate how the narrative changed from before to during the COVID-19 pandemic.

Methods

We obtained data using a textual query that scanned a data pool of approximately 200,000 different domains (4,027,172 documents and 361,100,284 words) such as public internet forums, blogs, and social media, from August 1, 2019, to April 21, 2020. We then used structural topic modeling to understand changes in word prevalence and semantic structures within topics around vaping before and after December 31, 2019, when COVID-19 was reported to the World Health Organization.

Results

Broadly, the web-based vaping narrative can be organized into the following groups or archetypes: harms from vaping; Vaping Regulation; Vaping as Harm Reduction or Treatment; and Vaping Lifestyle. Three archetypes were observed prior to the emergence of COVID-19; however, four archetypes were identified post–COVID-19 (Vaping as Harm Reduction or Treatment was the additional archetype). A topic related to CBD product preference emerged after COVID-19 was first reported, which may be related to the use of CBD by vapers as a COVID-19 treatment.

Conclusions

Our main finding is the emergence of a vape-administered CBD treatment narrative around COVID-19 when comparing the web-based vaping narratives before and during the COVID-19 pandemic. These results are key to understanding how vapers respond to inaccurate information about COVID-19, optimizing treatment of vapers who contract COVID-19, and possibly minimizing instances of inaccurate information. The findings have implications for the management of COVID-19 among vapers and the monitoring of web-based content pertinent to tobacco to develop targeted interventions to manage COVID-19 among vapers.
Event-Level Association Between Daily Alcohol Use and Same-Day Nonadherence to Antiretroviral Therapy Among Young Men Who Have Sex With Men and Trans Women Living With HIV: Intensive Longitudinal Study
Authors: Turner Caitlin Marie , Trujillo Dillon , Le Victory , Wilson Erin C , Arayasirikul Sean
Published: September 2020

Background

Young trans women (TW) and men who have sex with men (MSM) are disproportionately impacted by HIV. Optimizing adherence to antiretroviral therapy (ART) is one mechanism by which public health experts aim to achieve favorable HIV health outcomes while reducing disease transmission. However, alcohol use is prevalent among young TW and MSM and threatens optimal adherence. In addition, the daily variations in alcohol use and ART adherence and their association with each other are poorly understood, warranting more appropriate methodological approaches, such as analysis of ecological momentary assessment (EMA) data.

Objective

The aim of this analysis is to characterize the association between daily alcohol use and same-day ART nonadherence captured by an EMA study of young MSM and TW living with HIV in San Francisco.

Methods

Young MSM and TW enrolled in the Health eNav digital HIV care navigation intervention were included in the analytic sample (N=113). Data on alcohol and ART use were collected by daily EMA surveys administered via text messaging and were analyzed over 30 days of follow-up. A multivariable mixed-effects logistic regression model adjusting for baseline sociodemographic characteristics was specified to investigate whether daily alcohol use was associated with same-day ART nonuse.

Results

Daily alcohol use was associated with higher same-day ART nonuse. On average, participants drank alcohol on 15.20 (SD 8.93) days and used ART on 15.19 (SD 10.16) days out of 30 days. Daily alcohol use was associated with 1.89 (95% CI 1.14-3.15) times the adjusted odds of same-day ART nonuse for each participant.

Conclusions

Results are consistent with other analyses of daily alcohol and ART use and underscore the importance of individually targeted interventions that are sensitive to each participant’s dynamic risk environment.

Acceptability, feasibility and effectiveness of two methods of involving patients with disability in developing clinical guidelines: A single blind crossover trial (Preprint)
Authors: Lamontagne Marie-Eve , Gagnon Marie-Pierre , Perreault Kadija , Gauthier Véronique
Published: September 2020

BACKGROUND

There is a lack of robust knowledge about the best method to involve patients and population in clinical practice guidelines (CPG) development. This lack of evidence is a potential threat to the the quality of CPG in general and might have an impact on the adhesion of patients and providers to the guidelines and ultimately to the quality of care provided from them.

OBJECTIVE

The goal of this pilot trial is to document the acceptability, feasibility and effectiveness of two methods of involving patients in CPG development.

METHODS

A single-blind crossover pragmatic trial was performed with patients with traumatic brain injury (TBI). The patients experimented two alternative methods of producing clinical practice recommendations, i.e. a discussion group (control intervention) and a Wiki (experimental intervention). The participants rated the acceptability of the two methods, and feasibility was assessed using indicators such as the number of participants who completed the two methods and the number of support interventions required. Twenty experts, blinded to the method of producing the recommendations, independently rated the recommendations produced by the participants for clarity, accuracy, appropriateness and usefulness.

RESULTS

Twenty participants with TBI were recruited and sixteen completed the study. The acceptability of the two methods were found to be similar, despite qualitative comments indicate small preference for focus groups social characteristics. Both methods appeared highly feasible to involve patients in CPG development, and the experts’ perceived effectiveness was similar, despite the recommendation produced through focus group was deemed as more relevant to support the clinical practice.

CONCLUSIONS

Our results confirms previous observations about the acceptability and feasibility of focus group and wiki to allow patient and population to participate in clinical practice guideline production. It adds to the scientific literature establishing the similarity in effectiveness of the two methods.

A Personalized Monitoring Model for Electrocardiogram (ECG) Signals: Diagnostic Accuracy Study (Preprint)
Authors: Kotorov Rado , Chi Lianhua , Shen Min
Published: September 2020

BACKGROUND

Lately, the demand for remote ECG monitoring has increased drastically because of the COVID-19 pandemic. To prevent the spread of the virus and keep individuals with less severe cases out of hospitals, more patients are having heart disease diagnosis and monitoring remotely at home. The efficiency and accuracy of the ECG signal classifier are becoming more important because false alarms can overwhelm the system. Therefore, how to classify the ECG signals accurately and send alerts to healthcare professionals in timely fashion is an urgent problem to be addressed.

OBJECTIVE

The primary aim of this research is to create a robust and easy-to-configure solution for monitoring ECG signal in real-world settings. We developed a technique for building personalized prediction models to address the issues of generalized models because of the uniqueness of heartbeats [19]. In most cases, doctors and nurses do not have data science background and the existing Machine Learning models might be hard to configure. Hence a new technique is required if Remote Patient Monitoring will take off on a grand scale as is needed due to COVID-19. The main goal is to develop a technique that allows doctors, nurses, and other medical practitioners to easily configure a personalized model for remote patient monitoring. The proposed model can be easily understood and configured by medical practitioners since it requires less training data and fewer parameters to configure.

METHODS

In this paper, we propose a Personalized Monitoring Model (PMM) for ECG signal based on time series motif discovery to address this challenge. The main strategy here is to individually extract personalized motifs for each individual patient and then use motifs to predict the rest of readings of that patient by an artificial logical network.

RESULTS

In 32 study patients, each patient contains 30 mins of ECG signals/readings. Using our proposed Personalized Monitoring Model (PMM), the best diagnostic accuracy reached 100%. Overall, the average accuracy of PMM was always maintained above 90% with different parameter settings. For Generalized Monitoring Models (GMM1 and GMM2), the average accuracies were only around 80% with much more running time than PMM. Regardless of parameter settings, it normally took 3-4 mins for PMM to generate the training model. However, for GMM1 and GMM2, it took around 1 hour and even more with the increase of training data. The proposed model substantially speeds up the ECG diagnostics and effectively improve the accuracy of ECG diagnostics.

CONCLUSIONS

Our proposed PMM almost eliminates much training and small sample issues and is completely understandable and configurable by a doctor or a nurse.

The Indonesian Dairy Industry wa.s well developed until mid 1997, due to some government protective policies, such as credit far imported dam cattle. and domestic market security. (;orernment determined the Milk Ratio (the ratio between domestic fresh milk and imported milk) that should he satisfied/ by the multinational milk processors (IPS) to run their milk processing lactories. However, the domestic .fresh milk production was not sufficient to meet the raw material far their Jactories. Therefore, in 1996, about 67% of raw materials has w he imported, especially from Australia and New Zealand, At least there were m.o/actors resulting a high import of dairy product. First, the domestic dairy production capacity was limited: second the Indonesian dairy industry was considered as inefficient, so that the price of domesticfresh milk was claimed to be more expensive compared to imported milk. The economic crisis starting from mid 1997, resulting in a high price of imported dairy cattle and feed. On the other hand, this crisis also resulting in a significant increase in price of imported milk. Therefore, the demand for domestic fresh milk by IPS was significantly increased The observations in 6 milk cooperatives (in East and West Java) showed that since economic crisis, all fresh milk offered by all cooperatives to IPS was absorbed. Even IPS provided some incentives (higher price and bonus).* the farmers who have a better quality of milk. There was also price adjustment given by IPS from about Rp. 600 hr in 1996 97 to about Rp. 900 and then about Rp. 1100 ltr in 1998 99. However, the farmers was still complaining. because if they compare milk price to rice price, they recognize that before crisis I liter milk was equivalent to 0.6 kg rice, but after crisis 1 liter milk was equivalent to only 0.4 kg rice. The most important issue that should be anticipated is that "if exchange rate of Rupiah to US Dollar is increased, then imported milk will be cheaper, and IPS will tend to import milk rather than buying domestic fresh milk If this case is happening, it will be a nightmare to farmers who do dairy farm. Therefore, the development and transfer of the more efficient technology in dairy industry should be given a high priority.

PENYULUHAN PERTANIAN INDONESIA : ISU PRIVATISASI DAN IMPLIAKISNYA
Authors: Subejo Subejo
Published: September 2020

The organization, mandate, and practices of agricultural and rural extension systems are changing worldwide, and it is vital that each region keep pace with the latest developments. The challenges of introducing appropriate institutional measures must be accepted by each government in order to reform the national agricultural extension systems in response to the global changes, otherwise the extension systems will become obsolete.Diverse agricultural extension funding and delivery arrangements have been undertaken since the mid-1980s by governments worldwide in the name of "privatization". Privatization is used in the broadest sense of introducing or increasing private sector participation, which does not necessarily imply transfer of designated state-owned assets to the private sector. The arguments for privatization are based upon: more efficient delivery of service, lowered government expenditure. and higher quality of services. Privatization of agricultural extension system implies0 a division of appropriate role between public sector and private sector. Cost and service sharing among extension service providers can be formed into some systems encompass contract, vouchers, competitive grant fund, subsidize, and commercial extension service.This paper aims to discuss about privatization issues and its implications on Indonesian agricultural extension system. Related parties and sectors on Indonesian agricultural extension system should pay more attention in order to reform the old system and to reconstruct it into a new system--client-oriented extension
THE PERFORMANCE OF MAIZE VARIETIES IN SOME AGRO-ECOSYSTEMS OF EAST JAVA

Published: September 2020

Jagung merupakan tanaman pangan penting kedua setelah padi. Sekitar 64 % jagung diusahakan di Jawa dan memberikan sumbangan kira-kira 68 % terhadap produksi jagung nasional. Produktivitas jagung di Jawa Timur relatif lebih tinggi dibandingkan dengan rata-rata produktivitas nasional. Hal itu terutama karena penggunaan jenis jagung hibrida yang meluas di Jawa Timur. Meskipun demikian mayoritas petani khususnya di lahan kering dan lahan tadah hujan, mcngeluh tentang tingginya harga input dan rendahnya harga jual jagung. Petani di lahan kering dan tadah hujan kurang akses terhadap pasar, karena mereka jauh dari industri benih, pakan dan makanan olahan. Studi ini bertujuan menelaah penggunaan varietas jagung dan tingkat profitabilitasnya di beberapa agroekosistem di Jawa Timur. Hasil studi menunjukkan bahwa: (i) Jagung umumnya ditanam di lahan kering dan sebagian di lahan tadah hujan pada musim hujan, sedangkan pada musim kemarau, jagung diusahakan di sawah tadah hujan dan irigasi; (ii) jagung lokal khususnya diusahakan pada lahan kering dan tadah hujan, jagung hibrida ditanam di sawah irigasi dan sebagian kecil di sawah tadah hujan, sedangkan jagung turunan hibrida ditanam pada lahan tadah hujan-, (iii) penanaman jagung lokal umumnya ditujukan untuk konsumsi manusia, sedangkan jagung hibrida dan turunan hibrida untuk dijual dan (iv) tingkat produktivitas dan keuntungan paling tinggi diperoleh dari jagung hibrida murni yang ditanam di sawah irigasi. Beberapa kendala yang dihadapi petani dalam upaya meningkatkan produksi jagung adalah (a) rendahnya harga jual jagung selama musim panen; (b) tingginya harga input; (c) kurangnya promosi dari jagung komposit dan hibrida yang dihasilkan oleh pusat penelitian pemerintah, menyebabkan tingginya harga benih jagung dan (d) kurangnya modal usaha. Untuk mendorong petani dalam meningkatkan produksi jagung, pemerintah harus menyediakan subsidi benih yang layak. Pemerintah juga hams mendorong terjalinnya kerjasama saling menguntungkan antara pusat penelitian pemerintah dengan perusahaan swasta dalam hal pemuliaan jagung dan mempromosikan varietas jagung unggul baru yang dihasilkan dari kerjasama tersebut. Dengan demikian, diharapkan benih cukup tersedia dengan harga yang terjangkau. Upaha Iainnya adalah pemerintah Indonesia harus membatasi impor jagung dengan menerapkan tarif yang signifikan, mendorong pihak swasta untuk melakukan investasi dalam pabrik pakan yang dekat dengan sentra produksi jagung, mendirikan Bank Rakyat atau Bank Pertanian dimana para petani dapat akses langsung, dengan prosedur administrasi yang sederhana.
