Authors: Weeks Rose , White Sydney , Hartner Anna-Maria , Littlepage Shea , Wolf Jennifer , Masten Kristin , Tingey Lauren
Published: October 2022

Background

During the COVID-19 pandemic, tribal and health organizations used social media to rapidly disseminate public health guidance highlighting protective behaviors such as masking and vaccination to mitigate the pandemic’s disproportionate burden on American Indian and Alaska Native (AI/AN) communities.

Objective

Seeking to provide guidance for future communication campaigns prioritizing AI/AN audiences, this study aimed to identify Twitter post characteristics associated with higher performance, measured by audience reach (impressions) and web behavior (engagement rate).

Methods

We analyzed Twitter posts published by a campaign by the Johns Hopkins Center for Indigenous Health from July 2020 to June 2021. Qualitative analysis was informed by in-depth interviews with members of a Tribal Advisory Board and thematically organized according to the Health Belief Model. A general linearized model was used to analyze associations between Twitter post themes, impressions, and engagement rates.

Results

The campaign published 162 Twitter messages, which organically generated 425,834 impressions and 6016 engagements. Iterative analysis of these Twitter posts identified 10 unique themes under theory- and culture-related categories of framing knowledge, cultural messaging, normalizing mitigation strategies, and interactive opportunities, which were corroborated by interviews with Tribal Advisory Board members. Statistical analysis of Twitter impressions and engagement rate by theme demonstrated that posts featuring culturally resonant community role models (P=.02), promoting web-based events (P=.002), and with messaging as part of Twitter Chats (P<.001) were likely to generate higher impressions. In the adjusted analysis controlling for the date of posting, only the promotion of web-based events (P=.003) and Twitter Chat messaging (P=.01) remained significant. Visual, explanatory posts promoting self-efficacy (P=.01; P=.01) and humorous posts (P=.02; P=.01) were the most likely to generate high–engagement rates in both the adjusted and unadjusted analysis.

Conclusions

Results from the 1-year Twitter campaign provide lessons to inform organizations designing social media messages to reach and engage AI/AN social media audiences. The use of interactive events, instructional graphics, and Indigenous humor are promising practices to engage community members, potentially opening audiences to receiving important and time-sensitive guidance.
The PharmNet Harm Reduction Intervention for Community Pharmacies: Protocol for a Pilot Randomized Controlled Trial
Authors: Eldridge Lori Ann , Agley Jon , Meyerson Beth E , Golzarri-Arroyo Lilian
Published: October 2022

Background

The overdose epidemic in the United States has continued to worsen despite substantial efforts to mitigate its harms. The opioid antagonist naloxone has been identified as a key means of reducing the prevalence of fatal overdoses. An important evidence-based approach to optimizing naloxone’s impact is to seed it throughout the community, because bystanders are often able to reverse overdoses more quickly than first responders and sometimes are the only possible means of overdose reversal. As part of a multipronged approach to distributing naloxone nationwide, community pharmacies have been identified as ideal venues for naloxone dispensing, especially under standing orders. However, dispensing rates remain surprisingly low, and there is a need to understand how best to engage community pharmacies in naloxone-based harm reduction services.

Objective

The objective of this trial is to determine whether a tailored, pragmatic pharmacy intervention (PharmNet) results in greater naloxone dispensing relative to baseline (the prior 3 months) compared to a control condition. This pilot trial is intended to determine whether it is appropriate to invest the substantial resources that would be required to conduct a full-scale, randomized controlled study of PharmNet.

Methods

We will conduct a 3-month randomized controlled pilot trial consisting of 2 parallel groups with a 4:3 allocation ratio. A group of 7 independent pharmacies from rural areas in Indiana will be randomly assigned to either the PharmNet intervention arm (n=4) or the control arm (n=3). The primary outcome will be overall naloxone dispensing (both at cost and free), and secondary outcomes will include the distribution of referral cards and multiple variables at the level of individual staff members. Dispensing data will be collected for the 3 months prior to the intervention and the 3 months of the intervention, and all other data will be collected using a pretest-posttest design. The primary analysis will be a generalized linear mixed model with a Poisson distribution with fixed effects for group, time, and their interaction and a random effect for pharmacy ID to account for repeated measures within pharmacies.

Results

This study was approved by the Indiana University institutional review board in 2 phases (August 2, 2021, and April 26, 2022) and was funded by the Indiana University Grand Challenge: Responding to the Addictions Crisis.

Conclusions

If this study produces evidence that the PharmNet intervention results in increased naloxone dispensing relative to control pharmacies, it will be both appropriate and important to study it in a large, full-scale randomized controlled trial.

Authors: Gérardin Christel , Mageau Arthur , Mékinian Arsène , Tannier Xavier , Carrat Fabrice
Published: October 2022

Background

Reliable and interpretable automatic extraction of clinical phenotypes from large electronic medical record databases remains a challenge, especially in a language other than English.

Objective

We aimed to provide an automated end-to-end extraction of cohorts of similar patients from electronic health records for systemic diseases.

Methods

Our multistep algorithm includes a named-entity recognition step, a multilabel classification using medical subject headings ontology, and the computation of patient similarity. A selection of cohorts of similar patients on a priori annotated phenotypes was performed. Six phenotypes were selected for their clinical significance: P1, osteoporosis; P2, nephritis in systemic erythematosus lupus; P3, interstitial lung disease in systemic sclerosis; P4, lung infection; P5, obstetric antiphospholipid syndrome; and P6, Takayasu arteritis. We used a training set of 151 clinical notes and an independent validation set of 256 clinical notes, with annotated phenotypes, both extracted from the Assistance Publique-Hôpitaux de Paris data warehouse. We evaluated the precision of the 3 patients closest to the index patient for each phenotype with precision-at-3 and recall and average precision.

Results

For P1-P4, the precision-at-3 ranged from 0.85 (95% CI 0.75-0.95) to 0.99 (95% CI 0.98-1), the recall ranged from 0.53 (95% CI 0.50-0.55) to 0.83 (95% CI 0.81-0.84), and the average precision ranged from 0.58 (95% CI 0.54-0.62) to 0.88 (95% CI 0.85-0.90). P5-P6 phenotypes could not be analyzed due to the limited number of phenotypes.

Conclusions

Using a method close to clinical reasoning, we built a scalable and interpretable end-to-end algorithm for extracting cohorts of similar patients.

Authors: Lee Kyong-No , Kim Hyeon Ji , Choe Kiroong , Cho Aeri , Kim Bohyoung , Seo Jinwook , Myung Woojae , Park Jee Yoon , Oh Kyung Joon
Published: October 2022

BACKGROUND

Maternal-fetal attachment (MFA) has been reported to be associated with the postpartum mother-infant relationship. Seeing the fetus through ultrasound might influence MFA, and the effect could be increased by more realistic images, such as those generated in virtual reality (VR).

OBJECTIVE

The aim was to determine the effect of fetal images generated in VR on MFA and depressive symptoms through a prenatal-coaching mobile app.

METHODS

This 2-arm parallel randomized controlled trial involved a total of 80 pregnant women. Eligible women were randomly assigned to either a mobile app–only group (n=40) or an app plus VR group (n=40). The VR group experienced their own baby’s images generated in VR based on images obtained from fetal ultrasonography. The prenatal-coaching mobile app recommended health behavior for the pregnant women according to gestational age, provided feedback on entered data for maternal weight, blood pressure, and glucose levels, and included a private diary service for fetal ultrasound images. Both groups received the same app, but the VR group also viewed fetal images produced in VR; these images were stored in the app. All participants filled out questionnaires to assess MFA, depressive symptoms, and other basic medical information. The questionnaires were filled out again after the interventions.

RESULTS

Basic demographic data were comparable between the 2 groups. Most of the assessments showed comparable results for the 2 groups, but the mean score to assess interaction with the fetus was significantly higher for the VR group than the control group (0.4 vs 0.1, P=.004). The proportion of participants with an increased score for this category after the intervention was significantly higher in the VR group than the control group (43% vs 13%, P=.005). The feedback questionnaire revealed that scores for the degree of perception of fetal appearance all increased after the intervention in the VR group.

CONCLUSIONS

The use of a mobile app with fetal images in VR significantly increased maternal interaction with the fetus.

Review on Cognitive Mediation in Social Actor Representation in Discourse
Authors: Ghanim Sabra Hasan , Abed Prof. Ahmed Qadoury
Published: October 2022

This paper has set off to unearth how cognitive construal operations anchor social actor representation is discourse. Most of the previous literature resorted to different approaches to deal with the domain of social actor representation focusing on analyzing the text itself rather than taking into concertation how the given linguistic choices provoke different conceptualizations in the mind of the reader. Thus, the present paper seeks to address the association between social and cognitive aspects of the text. It is motivated by the lack of rigorous critical sociocognitive analysis that address the enacted ideology as a social and cognitive phenomenon. Furthermore, the paper highlights the crucial role of cognitive conceptual abilities as a mediator between text and society and recommends the adaptation of sociocognitive multimodal analysis to qualitatively and quantitatively analyse text to cover both descriptive and interpretive levels of analysis.
Assilation and Resistance in Hanif Kureishi’s The Black Album
Authors: Elyasi Faramarz
Published: October 2022

In the present study, Hanif Kureishi’s The Black Album was analyzed in the view of Bhabha’s concepts of ambivalence, assimilation, hybridity, double-consciousness, and homeliness. Shahid, a Pakistani student, constructs a hybrid identity and symbolically marries a widow lecturer who teaches postcolonial literature. On the contrary to Shahid’s views, Riaz’s group is a fundamental Islamic aggregation in 1980s London devoted to anti-racist activities while take part in book-burning and violent actions. As Bhabha theories about hybrid identity, it seems that Shahid’s assimilation into the host mainstream culture and developing a hybrid identity enfeebles colonial and imperial power more than Riaz’s group and their violent resistance against imperial power.

Published: October 2022

The increasing salinity of water and soil is one of the environmental factors that most threatens the sustainability of olive cultivation systems in the Mediterranean basin. The identification of plant material with high tolerance to this stress would be one of the ways to solve this challenge, but it is generally a slow and expensive process. The selection of the most reliably parameters involved in the response of the plant to salinity and that are easy to evaluate, could help to speed up the identification of the most tolerant genotypes. The objective of this study is to determine the most interesting morphological characters which could be used in future as early criteria in the selection process of olive tolerant genotypes. For that, young plants, three-month-old, were exposed to salinity (0, 4 and 8 g/L NaCl) during different periods of time (30, 50 and 70 days), and several morphological parameters were assessed. The obtained results showed that most of the parameters were affected by the concentration 8 g/L of NaCl after a treatment period of 50 days. The most affected parameters by this level of salinity were the plant height, the leaf number and the number of lateral shoots. The PCA analysis showed that the number of lateral shoots was poorly correlated with the other parameters, but the height and the leaf number were highly correlated with each other.
Practice and Thinking on Integrated Teaching of English Reading and Writing Units in Senior High School under the Background of "Double New" -- Take Unit 3, Compulsory 2 of Senior High School English of New Version of PEP as an Example
Authors: Liao Ruyuan
Published: October 2022

The "Double New" refers to new curriculum and new teaching materials for general high school. The "Double New" has put forward higher requirements for high school English teaching. The traditional high school English reading teaching is mostly pure reading teaching, which is difficult to combine reading and writing and realize the migration from reading to writing. It is difficult to combine reading and writing to achieve the transfer from reading to writing. The integration of reading and writing units can effectively solve this situation. This paper takes Unit 3 of Compulsory 2 of senior high school English of new version of PEP as an example to explain how teachers can realize the integration of reading and writing units in high school English in the context of the "Double New", and explores how to make high school English reading integrated around the six elements and develop the core English literacy through the analysis of unit texts, interpretation of teaching objectives and design of teaching activities. In this paper, we explore how to make high school English reading closely integrated with the six elements, develop the core English literacy, explore the connotation of the text, implement moral education, and realize the education of the subject.

Numerical Simulation of Stiffened Granular Pile
Authors: Gupta Himanshu
Published: October 2022

Abstract: Granular piles are suitable for increasing soft clay's strength and consolidation properties. Stone columns offer a practical, affordable solution for enhancing the earth and are crucial for stabilizing the soil. In order to carry higher shear stresses and prevent settlement, stone columns behaved as stiff elements, which enhanced the deformability and strength characteristics of the soft type of soil. The usage of granular piles has been shown to improve slope stability, increase bearing capacity, decrease differential and total settlements, decrease sand liquefaction, and lengthen settlement times. The present study studied the effect of stiffening on the granular pile using PLAXIS 2D. Mohr-Coulomb failure criterion was considered for the stone column, expansive soil, and granular material used for stiffening. The present study results are validated with the experimental results and are in good agreement. Numerical results show that stiffening in granular piles increases the load settlement response and stress transformation to a depth of granular pile and reduces the bulging

Authors: Susanti Elly
Published: October 2022

Thinking is a process of understanding various things encountered in everyday life, finding certain opinions or ideas, making judgments, and solving problems. One of the tasks teachers must do in learning mathematics is to help students convey the cognitive processes experienced when solving issues. The thinking errors are and the algorithms that are not yet complete in solving student problems. But in reality, students still have difficulties that cause errors in solving mathematical problems. This study describes the reflection strategy on thinking to correct students' misconceptions in solving mathematical problems. This type of research is descriptive research with a qualitative approach. Research data consists of student answers, results think aloud, and the results of semi-structured interviews. The results showed that students with low problem-solving abilities experienced assimilation at the stage of understanding the problem only. In contrast, at the scene of developing strategies and implementing plans, accommodation occurred. The students will attack because students can decompose problems into simpler ones but require reflection to connect mathematical material to solve problems. In addition, students also need thinking to correct errors and complete incomplete algorithms when carrying out plans for solving mathematical problems.

In the contemporary capitalism of flows, companies that strongly depend on territorial resources adopt social private policies so as to ensure the spatial insertion of their projects. In order to preserve their reputation, they also take part in a dispute for the legitimate representation of social space through the growing use of the visual instrument of diagrams. From among the corporate uses of diagrams, two types will be discussed herein. Whereas “corporate social responsibility” diagrams presuppose a harmonic space of partnership and cooperation, social risk mapping reveals the presence of dissensus and threats to the business climate. The text makes a critical reading of the business management literature and the diagrammatic material that composes it, and discusses diagrams published in the sustainability and corporate social responsibility reports of large corporations in the mineral extractive sector.

Evidence shows that half of the Adverse Drug Reactions (ADRs) resulting from Drug-Drug Interactions (DDI) are predictable and preventable. Hospitalized patients are more expected to develop DDI. The current study aims to assess the prevalence, risk factors, and severity of PDDIs among hospitalized patients. This is a cross-sectional study that was conducted in medical wards of a NGO charity hospital located in Bathalapalli, Anantapur district. Patients aged 18 years or more, and admitted to the in-patient medical wards taking more than one medication have been selected for the study. A total of 310 subjects who met the study criteria were enrolled in the study after taking oral and written informed consent. Patient demographics, a list of medications, and clinical characteristics were collected from admission to discharge by the review of medical records and patient interviews. The collected data were subjected to identify and grade the severity of PDDI by using IBM Micromedex® Drug Interaction Checker. Among 310 in-patients, 82 cases had 127 PDDI with a prevalence of 26.45%. The majority of the PDDI are moderate (57; 44.9%) in severity level. Factors like the advanced age group of more than 40 years, more than one comorbidity, staying in the hospital for more than four days, and more than five drugs per prescription were positively associated with having PDDI with a P value less than 0.05. Clinical pharmacists need to work with the healthcare team to provide interventions to reduce clinically significant interactions and improve clinical outcomes.

A jornada de experiências do cliente de fitness é observada nesta pesquisa exploratória, na qual 15 consumidores de duas academias orientadas para serviço, não membros de redes, sendo uma em Alphaville (Barueri/SP) e a outra na Savassi (Belo Horizonte/MG), participaram de entrevistas semiestruturadas. Das mais de três horas de gravação e uma centena de páginas de transcrição, foi possível propor um modelo conceitual de como o entrelaçamento das dimensões tangível, atendimento técnico e pertencimento permitem ao cliente a cocriação de valor na experiência de uso da academia. Concluiu-se que 1) os serviços também têm uma dimensão tangível; 2) apesar de toda a preparação acadêmico-tecnicista da equipe, os usuários querem coproduzir suas experiências; 3) o sentimento de pertencimento, além de engajar na cocriação de valor, é uma dimensão que pode aliviar qualquer desconforto advindo das experiências nas outras dimensões. A importância do pertencimento pode ser moderada pela autoeficácia do usuário.
Drivers of Differential Time to Diagnosis in Pediatric ALL tied to Race and Ethnicity

BACKGROUND: Acute lymphoblastic leukemia (ALL) is the most common
childhood malignancy, with diagnosis preceded by symptoms that may
include fever, weight loss, fatigue, bleeding and bruising. Timely
diagnosis and treatment of ALL may lead to improved outcomes and reduced
morbidity from associated complications including tumor lysis syndrome,
hyperviscosity, and stroke. PROCEDURE: We performed a retrospective
cohort analysis of 274 pediatric pre-B cell ALL and lymphoma patients
within Montefiore Health System to determine whether there were factors
associated with time from symptom onset to diagnosis. RESULTS: Median
time to diagnosis for all patients was 11.5 days (IQR7.8, 14.3) and was
similar between Hispanic, Non-Hispanic Black, and Non-Hispanic White
racial/ethnic groups (10.5 vs 14.0 vs 8.0 days; p=0.70), and by male and
female patients (14 vs 10 days; p=0.08). Those with Medicaid insurance
(n=189) were diagnosed sooner than those with private or self-pay
insurance (n=85) (median of 10 vs 16 days; p=0.05). Similar findings
were demonstrated when evaluating by Medicaid, Private, and Self-Pay
insurance types. English and Other language speakers experienced fewer
median days from symptom onset to diagnosis date compared to Spanish
speakers (11 vs 7 vs 14; p=0.05). Exploratory analyses suggest that
insurance status may impact the time to diagnosis to a greater degree in
Non-Hispanics, while English language and female sex may represent a
greater advantage to Hispanics. CONCLUSIONS: This study demonstrates
that insurance status and language preference may impact the time to
diagnosis of pediatric ALL. There is further need to confirm our
findings and to study possible causes driving these disparities.
A 43 bp-deletion in the F3'H gene reducing anthocyanins is responsible for buds-keeping-green at low temperature in broccoli

Most broccoli cultivars or accessions have green buds at an appropriate
growth environment. They would develop red or purple buds at cold
temperature, while some have green buds both at normal growth or cold
temperature. In this study, through BSA-seq, fine mapping and
transcriptome analyses, we identified a candidate gene ( F3’H)
responsible for reducing the accumulation of anthocyanins in a mutant GS
and HX-16 broccoli (DH line) ( Brassicaoleracea L. var.
italica), which would have caused green buds even at low
temperature. A 43-bp deletion was detected in the CDS of the F3’H
gene of HX-16 and mutant GS, which largely reduced the expression of
F3’H and the accumulation of cyanidin and delphinidin in the
mutant GS. The expression of F3’H was up-regulated at low
temperature in the wild line PS.The detection of 43-bp deletion in the
broccoli germplasm resources and other varietas in Brassica
oleracea showed that there could be other factors for green buds at low
temperature in Brassica oleracea. This study provides the
critical genetic and molecular information for the molecular breeding of
B. oleracea and illuminates the molecular basis of the
low-temperature effect on buds’ color in broccoli.

The article presents the results of a two-year work of the Clinical Infectious Diseases Hospital named after S.P. Botkin (Botkin Hospital) during the pandemic of a new coronavirus infection from March 01, 2020 to March 01, 2022. The characteristics of patients with a new coronavirus infection by age, severity of the disease, need for intensive care, including mechanical ventilation and ECMO, are given. Estimated hospital mortality from a new coronavirus infection. The contribution of concomitant infectious diseases (HIV infection, chronic viral hepatitis) to the lethality of patients with COVID-19 is presented. The volumes of assistance to pregnant women, women in childbirth and puerperas with COVID-19, as well as patients on program hemodialysis are presented. The structure of hospitalized patients according to nosological forms was analyzed. Against the backdrop of a massive influx of patients with COVID-19, a sharp decrease in hospitalization of patients with other infectious diseases was noted.
