Authors: Winecoff Ruth , Ayyagari Padmaja , McInerney Melissa , Simon Kosali , Bundorf M. Kate
Published: March 2021

Background: To examine racial and ethnic differences in wealth and other economic, exposure and baseline health-related risks of COVID-19 among older adults in the U.S. Methods: Using rich data on wealth and long-term care use among older Americans unique to the 2016 Health and Retirement Study, we quantify differences in COVID-19 vulnerability among non-Hispanic white, non-Hispanic Black and Hispanic respondents aged 50+. We measure wealth, other economic (insurance, income); exposure (long-term care, employment, telework, household size); and health (chronic conditions, smoking) risk stratified by age (50-64, 65+). Results: Blacks and Hispanics face dramatically greater financial risk that potentially increases exposure to COVID-19, relative to whites; Blacks and Hispanics are four to five times more likely to have no financial wealth. Blacks are also more likely than whites to use long-term care. Blacks and Hispanics also are less likely to have health insurance and face greater risk of exposure to COVID-19 because they are less likely to telework, and Hispanic older adults reside in larger households. Black and Hispanic older adults are also more likely to have a chronic condition associated with worse COVID-19 outcomes. Conclusions: Our results suggest that wealth differences may play a substantial role in contributing to the very large racial and ethnic disparities in the health burden of COVID-19. Racial disparities in long-term care, where COVID-19 risks are higher, contribute to make older Black Americans even more vulnerable to COVID-19.

Published: March 2021

Yixing Zisha ceramics are popular traditional tea sets with a long history in China but there are seldom studies to explore their compositions and microstructures. In this work, Benshanzhu-Zisha, a typical representation of Zisha from Yixing City of China, is investigated. The XRD results demonstrate that the Benshan Zhu clay is the natural mineral compound, which contains the high hematite content. After sintering, in comparison with pottery and porcelain, Benshanzhu-Zisha has the highest hematite (11.5 wt%) and amorphous phase (71.2 wt%) and the lowest mullite (10.7 wt%). Moreover, there are many dispersed and thin pores in Benshanzhu-Zisha ranging from nanometer to micron, and there are large numbers of hematite particles in the pores. It is the unique pore structures that make Benshanzhu-Zisha be perfect brewing tea vessel, impermeable to water but breathable to gas.

Authors: Shaodong Gu , Hong Luo , Yingxun Wang
Published: March 2021

Background：A drainage tube is generally retained after an abdominal surgery, especially in cases of postoperative bleeding or exudation. In recent years, negative pressure drainage or vacuum sealing drainage (VSD) has been extensively applied. However, the use of VSD in laparoscopic surgery is still challenging and has been rarely reported. Purpose: To introduce a novel Blake drain applied with negative pressure in laparoscopic surgeries. Materials/Methods: Two bar-shaped cuts were made at the end of the drainage tube, with one deeper than the other, and there were no other side holes retained. Thirty patients aged 4-8 years in novel drainage tube (NDT) group received the novel VSD after laparoscopic appendectomy or laparoscopic pyeloplasty, while those in the control traditional drainage tube (TDT) group received traditional drainage using the tube bearing side holes. Results：Tissue plugging and other complications were not observed in patients of NDT group. Significant differences were found in volume of drainage and cases of tissue plugging between NDT and TDT groups (P<0.05). Conclusions: The novel technique is simple, safe and effective for VSD following laparoscopic surgery. It can prevent plugging of soft tissues into the tube and improve drainage effect.

Published: March 2021

Coronavirus disease 2019 (SARS-CoV-2) (COVID-19) has recently raised worldwide public health
concerns. The available data on COVID-19 in patients with diabetes is limited but generally indicate that there
is an increased risk of developing COVID-19 infection in diabetic patients, which ultimately impacts the overall
patient’s survival. Various aspects might be involved; however, the exact mechanisms and interrelationships
between diabetes and the novel COVID-19 have not yet been fully elucidated. This review summarizes the possible
mechanisms by which present diabetes predispose individuals to COVID-19 infection, modulates the hostviral
interactions and increases the risk of mortality. We hope this review can provide beneficial information for
further studies and contribute to improved disease management of diabetic patients with COVID-19.
Adolescent Substance Abuse, Transgenerational Consequences and Epigenetics
Authors: Salmanzadeh Hamed , Ahmadi-Soleimani S. Mohammad , Azadi Maryam , Halliwell Robert F. , Azizi Hossein
Published: March 2021

Adolescence is the transitional period between childhood and adulthood and a critical
period in brain development. Adolescence in humans is also associated with increased expression of
risk-taking behaviors. Epidemiological and clinical studies, for example, show a surge of drug
abuse and raise the hypothesis that the adolescent brain undergoes critical changes resulting in diminished
control. Determining how substance abuse during this critical period might cause longterm
neurobiological changes in cognition and behavior is therefore critically important. The present
work aims to provide an evaluation of the transgenerational and multi-generational phenotypes
derived from parent animals exposed to drugs of abuse only during their adolescence. Specifically,
we will consider changes found following the administration of cannabinoids, nicotine, alcohol and
opiates. In addition, epigenetic modifications of the genome following drug exposure will be discussed
as emerging evidence of the underlying adverse transgenerational effects. Notwithstanding,
much of the new data discussed here is from animal models, indicating that future clinical studies
are much needed to better understand the neurobiological consequences and mechanisms of drug
actions on the human brains’ development and maturation.
Fabrication of Electrochemical Sensor for Epinine Determination Amplified with MgO/CNTs Nanocomposite and Ionic Liquid
Authors: Shahraki Shirin , Masrournia Mahboubeh , Karimi-Maleh Hassan
Published: March 2021

Background:

Catecholamines are a large group of pharmacological and biological compounds that are widely used in biological systems. These compounds are prepared both naturally and synthetically with many key roles in the human body and its activities. Therefore, many researchers focused on the identification and determination of catecholamines in biological samples.

Methods:

MgO/SWCNTs were synthesized through the chemical precipitation method. In addition, cyclic voltammetry, differential pulse voltammetry, and chronoamperometric methods were used for the electro-oxidation reaction study of epinine at the surface of the modified electrode.

Results:

Carbon paste electrode (CPE) modified with MgO/SWCNTs nanocomposite and 1-butyl- 3-methylimidazolium methanesulfonate (BMMS) was used as an electrochemical sensor for the determination of epinine. The results showed a linear dynamic range of 5.0 nM-250 μM with a detection limit of 0.1 nM for epinine determination using MgO/SWCNTs/BMMS/CPE as a sensor.

Conclusion:

In the present study, a highly sensitive electrochemical sensor was designed and fabricated as an analytical tool for the determination of epinine. MgO/SWCNTs/BMMS/CPE was successfully used for the determination of epinine in water and dextrose saline with an acceptable recovery range of 98.7%-102.72%.
Analytical Methods for the Identification of Pigments in Tattoo Inks and Some of Their Physiological Side Effects: A Review
Authors: Al-Qaysi Wafaa Waleed , Hammood Mohammad K. , Tawfeeq Eqbal Naji
Published: March 2021

In this review, numerous analytical methods to distinguish pigments in tattoo, paint,
and ink items are discussed. The selection of a method was dependent upon the purpose, e.g.,
quantification or identification of pigments. The introductory part of this review focuses on describing
the importance of setting up a pigment-associated safety profile. The formation of different
degradation chemical substances as well as impurity trends can be indicated through the
chemical investigation of pigments in tattoo products. It is noteworthy that pigment recognition
in tattoo inks can work as a preliminary method to identify the pigments in a patient's tattoo before
being removed by laser therapy. Contrary to the study of banned pigments, the identification
process usually requires only a few indication substances for positive dyes. In general, tattoo
pigments are almost insoluble in aqueous solutions, and many organic solvents and various pigment
analyses have been conducted. It is proposed that in the future, laboratories concerned with
tattoo substance analysis should have access to extensive pigment specifications and spectroscopic
databases. The most important and recent physiological side effects of tattooing have
been discussed in this review.
Adolescent Peer Influence on Eating Behaviors via Social Media: Scoping Review
Authors: Chung Alicia , Vieira Dorice , Donley Tiffany , Tan Nicholas , Jean-Louis Girardin , Kiely Gouley Kathleen , Seixas Azizi
Published: March 2021

Background

The influence of social media among adolescent peer groups can be a powerful change agent.

Objective

Our scoping review aimed to elucidate the ways in which social media use among adolescent peers influences eating behaviors.

Methods

A scoping review of the literature of articles published from journal inception to 2019 was performed by searching PubMed (ie, MEDLINE), Embase, CINAHL, PsycINFO, Web of Science, and other databases. The review was conducted in three steps: (1) identification of the research question and clarification of criteria using the population, intervention, comparison, and outcome (PICO) framework; (2) selection of articles from the literature using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines; and (3) charting and summarizing information from selected articles. PubMed’s Medical Subject Headings (MeSH) and Embase’s Emtree subject headings were reviewed along with specific keywords to construct a comprehensive search strategy. Subject headings and keywords were based on adolescent age groups, social media platforms, and eating behaviors. After screening 1387 peer-reviewed articles, 37 articles were assessed for eligibility. Participant age, gender, study location, social media channels utilized, user volume, and content themes related to findings were extracted from the articles.

Results

Six articles met the final inclusion criteria. A final sample size of 1225 adolescents (aged 10 to 19 years) from the United States, the United Kingdom, Sweden, Norway, Denmark, Portugal, Brazil, and Australia were included in controlled and qualitative studies. Instagram and Facebook were among the most popular social media platforms that influenced healthful eating behaviors (ie, fruit and vegetable intake) as well as unhealthful eating behaviors related to fast food advertising. Online forums served as accessible channels for eating disorder relapse prevention among youth. Social media influence converged around four central themes: (1) visual appeal, (2) content dissemination, (3) socialized digital connections, and (4) adolescent marketer influencers.

Conclusions

Adolescent peer influence in social media environments spans the spectrum of healthy eating (ie, pathological) to eating disorders (ie, nonpathological). Strategic network-driven approaches should be considered for engaging adolescents in the promotion of positive dietary behaviors.
Public Discourse Against Masks in the COVID-19 Era: Infodemiology Study of Twitter Data
Authors: Al-Ramahi Mohammad , Elnoshokaty Ahmed , El-Gayar Omar , Nasralah Tareq , Wahbeh Abdullah
Published: March 2021

Background

Despite scientific evidence supporting the importance of wearing masks to curtail the spread of COVID-19, wearing masks has stirred up a significant debate particularly on social media.

Objective

This study aimed to investigate the topics associated with the public discourse against wearing masks in the United States. We also studied the relationship between the anti-mask discourse on social media and the number of new COVID-19 cases.

Methods

We collected a total of 51,170 English tweets between January 1, 2020, and October 27, 2020, by searching for hashtags against wearing masks. We used machine learning techniques to analyze the data collected. We investigated the relationship between the volume of tweets against mask-wearing and the daily volume of new COVID-19 cases using a Pearson correlation analysis between the two-time series.

Results

The results and analysis showed that social media could help identify important insights related to wearing masks. The results of topic mining identified 10 categories or themes of user concerns dominated by (1) constitutional rights and freedom of choice; (2) conspiracy theory, population control, and big pharma; and (3) fake news, fake numbers, and fake pandemic. Altogether, these three categories represent almost 65% of the volume of tweets against wearing masks. The relationship between the volume of tweets against wearing masks and newly reported COVID-19 cases depicted a strong correlation wherein the rise in the volume of negative tweets led the rise in the number of new cases by 9 days.

Conclusions

These findings demonstrated the potential of mining social media for understanding the public discourse about public health issues such as wearing masks during the COVID-19 pandemic. The results emphasized the relationship between the discourse on social media and the potential impact on real events such as changing the course of the pandemic. Policy makers are advised to proactively address public perception and work on shaping this perception through raising awareness, debunking negative sentiments, and prioritizing early policy intervention toward the most prevalent topics.
Mentorship program in a tertiary care private medical college of Eastern India: evaluation, appraisal and recommendations (Preprint)
Authors: Das Dipmala , Deb Roy Asitava , Rawekar Alka
Published: March 2021

BACKGROUND

Mentorship programs are becoming increasingly common in undergraduate medical education all over the world. However, very few medical colleges are running mentorship programs in India. A mentorship program was introduced in our college for the first year MBBS students to help them cope up with the stress of the new environment.

OBJECTIVE

The aim of this study is to evaluate the mentorship program with regard to its efficacy, utility, limitation and potential for improvement after successful completion of one year of the program.

METHODS

It was an observational analytical study including 143 mentees and 15 mentors conducted in a tertiary care teaching hospital for five months from November 2019 to March 2020. Two sessions of FGD were carried out involving 7 students in each session. One session of FGD was conducted involving 7 mentors. The feedback was collected with a pre validated questionnaire containing 10 questions (8 close ended and 2 open ended). Feedback of closed ended questions were obtained by using a 5-point Likert scale (1 to 5) where 5 indicated ‘Strongly Agree’ and 1 indicated ‘Strongly Disagree’

RESULTS

Most of the mentees (86.7%) and mentors (66.7%) mentioned that mentorship program is necessary for the welfare of the students. However, it was also noted that better communication and frequent meetings can improve the outcome of the program.

CONCLUSIONS

Mentorship program is deemed essential, however, a well-structured framework and dedicated time from both mentors and mentees will make the program more successful. This type of feedback evaluation is however important to validate such program.
A Transdiagnostic, Emotion Regulation App (Eda) for Children: Design, Development, and Lessons Learned (Preprint)
Authors: Moltrecht Bettina , Patalay Praveetha , Bear Holly Alice , Deighton Jessica , Edbrooke-Childs Julian
Published: March 2021

BACKGROUND

Digital interventions, including mobile apps, represent a promising means of providing effective mental health support to children and young people. Despite the increased availability of mental health apps, there is a significant gap for this age group, especially for children (aged 10-12 years). Research investigating the effectiveness and development process of child mental health apps is limited, and the field faces persistent issues in relation to low user uptake and engagement, which is assumed to be a result of limited user involvement in the design process.

OBJECTIVE

This study aims to present the development and design process of a new mental health app for children that targets their emotion regulation abilities. We describe the creation of a new interdisciplinary development framework to guide the design process and explain how each activity informed different app features.

METHODS

The first 2 stages of the framework used a variety of methods, including weekly classroom observations over a 6-month period (20 in total); public engagement events with the target group (N=21); synthesis of the existing evidence as part of a meta-analysis; a series of co-design and participatory workshops with young users (N=33), clinicians (N=7), researchers (N=12), app developers (N=1), and designers (N=2); and finally, testing of the first high-tech prototype (N=15).

RESULTS

For the interdisciplinary framework, we drew on methods derived from the Medical Research Council framework for complex interventions, the patient–clinician framework, and the Druin cooperative inquiry. The classroom observations, public engagement events, and synthesis of the existing evidence informed the first key pillars of the app and wireframes. Subsequently, a series of workshops shaped and reshaped the content and app features, including games, psychoeducational films, and practice modules. On the basis of the prototype testing sessions, we made further adjustments to improve the app.

CONCLUSIONS

Although mobile apps could be highly suitable to support children’s mental health on a wider scale, there is little guidance on how these interventions could be designed and developed. The involvement of young users across different design activities is very valuable. We hope that our interdisciplinary framework and description of the used methods will be helpful to others who are hoping to develop mental health apps for children and young people.

The effect of the cover crops, narbon vetch (Vicia narbonensis), oat (Avena sativa), forage radish (Raphanus sativus), on weed suppressionandsoil nitrogenwas studied in field conditions overwinter. The impact of their residues on the productivity of a subsequent corn crop was followed in the summerof the same year. Between mid-November andMarch oat produced, on a dry weight basis,915 g m-2against 402 g m-2for narbon vetch and 292 g m-2for radish. Consequently, weeds were suppressed best in the presence of oat. Narbon vetchwas less effective than radishin controlling weeds, as it was slowerto get established. In terms of mineral nitrogen, soils occupied by radish (13.1 mg kg-1soil) presented smaller concentrations of ammonium-Nthanthose by vetch(18.7 mg kg-1soil)and the control(19.7 mg kg-1soil). Following the overwinter covercrops, plots were split intoone half whereroots only were incorporated,and another half receivingwhole plants. Residues of whole plants promoted higher production of corn in the booting and flowering stages, as compared to roots only. At the 50% doughstage, the highest dry matter yield was 7.6 Mgha-1afternarbon vetch. Cornyield was the smallest after oat, due to N immobilization. This was demonstrated, using the litter bag technique, when oat residues (15.6g N kg-1) lost 31% of their N against 66% for radishresidues(21.1g N kg-1).For an effective control of weeds and nutrient recycling a cover crop, such as oat, is most efficient. In this case, the succeeding summer crop needs to receive some extra nitrogen.

Authors: Yanti Eka Safitri
Published: March 2021

Latar Belakang: Menyusui merupakan masa yang tidak mudah bagi seorang ibu. Harapan seorang ibu tentunya dapat menyusui secara penuh dalam 6 bulan pertama kehidupan bayinya. Namun sayangnya, ibu menyusui sering menghadapi berbagai masalah dalam perawatan bayi yang mengakibatkan terganggunya pemberian ASI seperti stress karena belum beradaptasi dalam perannya menjadi seorang ibu, atau karena tekanan dari lingkungan sekitarnya. Peran pasangan sangat penting dalam membantu ibu mengatasi masalah-masalah yang mungkin timbul. Dukungan pasangan dapat membantu ibu terutama dalam koping ibu dalam menangani stress yang mungkin timbul saat menyusui. Tujuan: Tujuan dari penelitian ini adalah untuk mengetahui dukungan ayah ASI berupa finansial, fisik maupun emosional terhadap keberhasilan ASI eksklusif pada masa antepartum, intrapartum dan masa menyusui. Metode: Metode penelitian ini menggunakan desain cross sectional yang dilakukan di Desa Tanjung Gunung Kabupaten Bangka Tengah Provinsi Kepulauan Bangka Belitung. Penelitian dilakukan kepada 35 pasangan suami istri yang memiliki bayi usia 6 bulan hingga 1 tahun. Hasil: Hasil analisis statistik didapatkan bahwa tidak terlihat hubungan yang signifikan antara dukungan ayah (finansial, fisik dan emosional) yang diberikan pada masa antepartum (p=0,285), intrapartum (p=0,730) hingga masa menyusui (p=0,282) terhadap keberhasilan ASI eksklusif. Walau demikian, dukungan ini menjadi bermakna jika ayah memberikan dukungan sepanjang masa kehamilan hingga 6 bulan masa menyusui tanpa ada satu periode pun yang terlewat (p=0,013). Kesimpulan: Hal ini memperlihatkan bahwa dukungan ayah (finansial, fisik dan emosional) harus dilakukan sepanjang masa antepartum, intrapartum dan masa menyusui untuk dapat menentukan keberhasilan ASI eksklusif.

Persuasive communication is one of the studies of communication that is often used as a method of influencing others in various ways, including in the field of sales. Persuasive messages are seen as a conscious effort to change thoughts and actions by manipulating motives in the direction of a predetermined goal. Decision making is an integration process that combines knowledge to evaluate two or more alternative behaviors and choose one of them. The independent variable in this study is persuasive messages and the dependent variable is the purchasing decision. This type of research is quantitative descriptive. The research data collected uses non probability sampling and purposive sampling techniques. This study uses SPSS for Windows 15 test for Validity, Reliability, Simple Linear Analysis Hypothesis, Correlation Coefficient, Determination Coefficient, Regression Analysis, and T-Test. and represent the population. The results of research conducted by researchers that persuasive messages influence as much as 39.4% in purchasing decisions, while the remaining 60.6% is influenced by other factors. Research also shows that if persuasive messages are improved, purchasing decisions will also increase. Komunikasi persuasif merupakan salah satu kajian komunikasi yang kerap digunakan sebagai metode mempengaruhi orang lain dalam berbagai hal, termasuk diantaranya dalam bidang penjualan.

Optimal Bacon-Shor codes
Authors: Napp John , Preskill John
Published: March 2021

We study the performance of Bacon-Shor codes, quantum subsystem codes which are well suited for applications to fault-tolerant quantum memory because the error syndrome can be extracted by performing two-qubit measurements. Assuming independent noise, we find the optimal block size in terms of the bit-flip error probability $p_X$ and the phase error probability $p_Z$, and determine how the probability of a logical error depends on $p_X$ and $p_Z$. We show that a single Bacon-Shor code block, used by itself without concatenation, can provide very effective protection against logical errors if the noise is highly biased ($p_Z/p_X\gg 1)$ and the physical error rate $p_Z$ is a few percent or below. We also derive an upper bound on the logical error rate for the case where the syndrome data is noisy.
Detector-Free Photothermal Bar-Chart Microfluidic Chips (PT-Chips) for Visual Quantitative Detection of Biomarkers

Published: March 2021

The volumetric bar-chart microfluidic chips (V-Chips) driven by chemical reaction-generated gas provide a promising platform for point-of-care (POC) visual biomarker quantitation. However, multiple limitations are encountered in conventional V-Chips, such as costly and complex chip fabrication, complicated assembly, and imprecise controllability of gas production. Herein, we introduced nanomaterial-mediated photothermal effects to V-Chips, and for the first time developed a new type of V-Chip, photothermal bar-chart microfluidic chip (PT-Chip), for visual quantitative detection of biochemicals without any bulky and costly analytical instruments. Immunosensing signals were converted to visual readout signals via photothermal effects, the on-chip bar-chart movements, enabling quantitative biomarker detection on a low-cost polymer hybrid PT-Chip with on-chip scale rulers. Four different human serum samples containing prostate-specific antigen (PSA) as a model analyte were detected simultaneously using the PT-Chip, with the limit of detection of 2.1 ng/mL, meeting clinical diagnostic requirements. Although no conventional signal detectors were used, it achieved comparable detection sensitivity to absorbance measurements with a microplate reader. The PT-Chip was further validated by testing human whole blood without the color interference problem, demonstrating good analytical performance of our method even in complex matrixes and thus the potential to fill a gap in current clinical diagnostics that is incapable of testing whole blood. This new PT-Chip driven by nanomaterial-mediated photothermal effects opens a new horizon of microfluidic platforms for instrument-free diagnostics at the point of care.
