Facilitators and Barriers to the Adoption of Telemedicine During the First Year of COVID-19: Systematic Review
Authors: Kruse Clemens , Heinemann Katharine
Published: November 2021

Background

The virulent and unpredictable nature of COVID-19 combined with a change in reimbursement mechanisms both forced and enabled the rapid adoption of telemedicine around the world. Thus, it is important to now assess the effects of this rapid adoption and to determine whether the barriers to such adoption are the same today as they were under prepandemic conditions.

Objective

The objective of this systematic literature review was to examine the research literature published during the COVID-19 pandemic to identify facilitators, barriers, and associated medical outcomes as a result of adopting telemedicine, and to determine if changes have occurred in the industry during this time.

Methods

The systematic review was performed in accordance with the Kruse protocol and the results are reported in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We analyzed 46 research articles from five continents published during the first year of the COVID-19 pandemic that were retrieved from searches in four research databases: PubMed (MEDLINE), CINAHL, Science Direct, and Web of Science.

Results

Reviewers identified 25 facilitator themes and observations, 12 barrier themes and observations, and 14 results (compared to a control group) themes and observations. Overall, 22% of the articles analyzed reported strong satisfaction or satisfaction (zero reported a decline in satisfaction), 27% reported an improvement in administrative or efficiency results (as compared with a control group), 14% reported no statistically significant difference from the control group, and 40% and 10% reported an improvement or no statistically significant difference in medical outcomes using the telemedicine modality over the control group, respectively.

Conclusions

The pandemic encouraged rapid adoption of telemedicine, which also encouraged practices to adopt the modality regardless of the challenges identified in previous research. Several barriers remain for health policymakers to address; however, health care administrators can feel confident in the modality as the evidence largely shows that it is safe, effective, and widely accepted.
Nutrient and Food Group Prediction as Orchestrated by an Automated Image Recognition System in a Smartphone App (CALO mama): Validation Study
Authors: Sasaki Yuki , Sato Koryu , Kobayashi Satomi , Asakura Keiko
Published: November 2021

Background

A smartphone image recognition app is expected to be a novel tool for measuring nutrients and food intake, but its performance has not been well evaluated.

Objective

We assessed the accuracy of the performance of an image recognition app called CALO mama in terms of the nutrient and food group contents automatically estimated by the app.

Methods

We prepared 120 meal samples for which the nutrients and food groups were calculated. Next, we predicted the nutrients and food groups included in the meals from their photographs by using (1) automated image recognition only and (2) manual modification after automatic identification.

Results

Predictions generated using only image recognition were similar to the actual data on the weight of meals and were accurate for 11 out of 30 nutrients and 4 out of 15 food groups. The app underestimated energy, 19 nutrients, and 9 food groups, while it overestimated dairy products and confectioneries. After manual modification, the predictions were similar for energy, accurately capturing the nutrients for 29 out of 30 of meals and the food groups for 10 out of 15 meals. The app underestimated pulses, fruits, and meats, while it overestimated weight, vitamin C, vegetables, and confectioneries.

Conclusions

The results of this study suggest that manual modification after prediction using image recognition improves the performance of the app in assessing the nutrients and food groups of meals. Our findings suggest that image recognition has the potential to achieve a description of the dietary intakes of populations by using “precision nutrition” (a comprehensive and dynamic approach to developing tailored nutritional recommendations) for individuals.

Authors: Vaingankar Janhavi Ajit , van Dam Rob M , Samari Ellaisha , Chang Sherilyn , Seow Esmond , Chua Yi Chian , Luo Nan , Verma Swapna , Subramaniam Mythily
Published: November 2021

Background

Social media influence almost every aspect of our lives by facilitating instant many-to-many communication and self-expression. Recent research suggests strong negative and positive impacts of social media exposure on youth mental health; however, there has been more emphasis on harmful relationships.

Objective

Given the limited research on the benefits of social media for mental health, this qualitative study explored the lived experiences of youth to understand how social media use can contribute to positive mental health among youth.

Methods

Using an interpretivist epistemological approach, 25 semistructured interviews and 11 focus group discussions were conducted with male and female youth of different ethnicities (aged 15 to 24 years) residing in Singapore, who were recruited through purposive sampling from the community. We conducted inductive thematic analysis and concept mapping to address the research aims.

Results

We found that youth engaged in a wide range of activities on social media from connecting with family and friends to participating in global movements, and these served as avenues for building positive mental health. Based on participants’ narratives, our analysis suggested that positive mental health among youth could be influenced by 3 features of social media consumption (connection with friends and their global community, engagement with social media content, and the value of social media as an outlet for expression). Through these, pathways leading to the following 5 positive mental health components were identified: (1) positive relationships and social capital, (2) self-concept, (3) coping, (4) happiness, and (5) other relevant aspects of mental health (for example, positivity and personal growth).

Conclusions

The study results highlight the integral role of social media in the lives of today’s youth and indicate that they can offer opportunities for positive influence, personal expression, and social support, thus contributing to positive mental health among youth. The findings of our research can be applied to optimize engagement with youth through social media and enhance the digital modes of mental health promotion.

Authors: Sasaki Natsu , Obikane Erika , Vedanthan Rajesh , Imamura Kotaro , Cuijpers Pim , Shimazu Taichi , Kamada Masamitsu , Kawakami Norito , Nishi Daisuke
Published: November 2021

BACKGROUND

Digital mental health interventions are being used more than ever for the prevention and treatment of psychological problems. Optimizing the implementation aspects of digital mental health is essential to deliver the program to populations in need, but there is a lack of validated implementation outcome measures for digital mental health interventions.

OBJECTIVE

The primary aim of this study is to develop implementation outcome scales of digital mental health for different levels of stakeholders involved in the implementation process: users, providers, and managers or policy makers. The secondary aim is to validate the developed scale for users.

METHODS

We developed English and Japanese versions of the implementation outcome scales for digital mental health (iOSDMH) based on the literature review and panel discussions with experts in implementation research and web-based psychotherapy. The study developed acceptability, appropriateness, feasibility, satisfaction, and harm as the outcome measures for users, providers, and managers or policy makers. We conducted evidence-based interventions via the internet using UTSMeD, a website for mental health information (N=200). Exploratory factor analysis (EFA) was conducted to assess the structural validity of the iOSDMH for users. Satisfaction, which consisted of a single item, was not included in the EFA.

RESULTS

The iOSDMH was developed for users, providers, and managers or policy makers. The iOSDMH contains 19 items for users, 11 items for providers, and 14 items for managers or policy makers. Cronbach α coefficients indicated intermediate internal consistency for acceptability (α=.665) but high consistency for appropriateness (α=.776), feasibility (α=.832), and harm (α=.777) of the iOSDMH for users. EFA revealed 3-factor structures, indicating acceptability and appropriateness as close concepts. Despite the similarity between these 2 concepts, we inferred that acceptability and appropriateness should be used as different factors, following previous studies.

CONCLUSIONS

We developed iOSDMH for users, providers, and managers. Psychometric assessment of the scales for users demonstrated acceptable reliability and validity. Evaluating the components of digital mental health implementation is a major step forward in implementation science.
Understanding “Atmosome”, the Personal Atmospheric Exposome: Comprehensive Approach (Preprint)
Authors: Bhimaraju Hari , Nag Nitish , Pandey Vaibhav , Jain Ramesh
Published: November 2021

BACKGROUND

Modern environmental health research extensively focuses on outdoor air pollutants and their effects on public health. However, research on monitoring and enhancing individual indoor air quality is lacking. The field of exposomics encompasses the totality of human environmental exposures and its effects on health. A subset of this exposome deals with atmospheric exposure, termed the “atmosome.” The atmosome plays a pivotal role in health and has significant effects on DNA, metabolism, skin integrity, and lung health.

OBJECTIVE

The aim of this work is to develop a low-cost, comprehensive measurement system for collecting and analyzing atmosomic factors. The research explores the significance of the atmosome in personalized and preventive care for public health.

METHODS

An internet of things microcontroller-based system is introduced and demonstrated. The system collects real-time indoor air quality data and posts it to the cloud for immediate access.

RESULTS

The experimental results yield air quality measurements with an accuracy of 90% when compared with precalibrated commercial devices and demonstrate a direct correlation between lifestyle and air quality.

CONCLUSIONS

Quantifying the individual atmosome is a monumental step in advancing personalized health, medical research, and epidemiological research. The 2 main goals in this work are to present the atmosome as a measurable concept and to demonstrate how to implement it using low-cost electronics. By enabling atmosome measurements at a communal scale, this work also opens up potential new directions for public health research. Researchers will now have the data to model the impact of indoor air pollutants on the health of individuals, communities, and specific demographics, leading to novel approaches for predicting and preventing diseases.
Is the Teleophthalmology Diagnosis and Treatment System a Safe, Economic, and Sustainable Technology in Low- and Middle-Income Countries? (Preprint)
Authors: Li Ruyue , Wang Ningli , Liu Hanruo
Published: November 2021

UNSTRUCTURED

Following the rapid development of telemedicine, some emerging technologies, such as teleophthalmology screening or treatment systems, are gradually introduced not only in high-income countries but also in low- and middle-income countries, and their clinical safety and economy have been confirmed through researches based on virtual models. However, up to now, there is still not a comprehensive and systematic teleophthalmology diagnosis and treatment system, and the follow-up health economic evaluation of this system is still lacking in the real world. In this viewpoint, we describe the potential strengths and challenges of teleophthalmology diagnosis and treatment system. Under the guidance of this viewpoint, policy makers in low- and middle-income countries can complete the health economic assessment of this system, and promote its popularization and application in county hospitals.
Physicians’ Attitudes Toward Prescribable mHealth Apps and Implications for Adoption in Germany: Mixed Methods Study (Preprint)
Authors: Dahlhausen Florian , Zinner Maximillian , Bieske Linn , Ehlers Jan P , Boehme Philip , Fehring Leonard
Published: November 2021

BACKGROUND

In October 2020, Germany became the first country, worldwide, to approve certain mobile health (mHealth) apps, referred to as DiGA (Digitale Gesundheitsanwendungen, in German, meaning digital health applications), for prescription with costs covered by standard statutory health insurance. Yet, this option has only been used to a limited extent so far.

OBJECTIVE

The aim of this study was to investigate physicians’ and psychotherapists’ current attitudes toward mHealth apps, barriers to adoption, and potential remedies.

METHODS

We conducted a two-stage sequential mixed methods study. In phase one, semistructured interviews were conducted with physicians and psychotherapists for questionnaire design. In phase two, an online survey was conducted among general practitioners, physicians, and psychotherapists.

RESULTS

A total of 1308 survey responses by mostly outpatient-care general practitioners, physicians, and psychotherapists from across Germany who could prescribe DiGA were recorded, making this the largest study on mHealth prescriptions to date. A total of 62.1% (807/1299) of respondents supported the opportunity to prescribe DiGA. Improved adherence (997/1294, 77.0%), health literacy (842/1294, 65.1%), and disease management (783/1294, 60.5%) were most frequently seen as benefits of DiGA. However, only 30.3% (393/1299) of respondents planned to prescribe DiGA, varying greatly by medical specialty. Professionals are still facing substantial barriers, such as insufficient information (1135/1295, 87.6%), reimbursement for DiGA-related medical services (716/1299, 55.1%), medical evidence (712/1298, 54.9%), legal uncertainties (680/1299, 52.3%), and technological uncertainties (658/1299, 50.7%). To support professionals who are unsure of prescribing DiGA, extended information campaigns (1104/1297, 85.1%) as well as recommendations from medical associations (1041/1297, 80.3%) and medical colleagues (1024/1297, 79.0%) were seen as the most impactful remedies.

CONCLUSIONS

To realize the benefits from DiGA through increased adoption, additional information sharing about DiGA from trusted bodies, reimbursement for DiGA-related medical services, and further medical evidence are recommended.

Authors: Ewais Tatjana , Hunt Georgia , Munro Jonathan , Pun Paul , Hogan Christy , William Leeroy , Teodorczuk Andrew
Published: November 2021

BACKGROUND

Schwartz Rounds are a unique, organization-wide interdisciplinary intervention aimed at enhancing staff well-being, compassionate care, teamwork, and organizational culture in health care settings. They provide a safe space wherein both clinical and nonclinical health staff can connect and share their experiences about the social and emotional aspects of health care.

OBJECTIVE

Although Schwartz Rounds have been assessed and widely implemented in the United States and United Kingdom, they are yet to be formally evaluated in Australian health care settings. The purpose of this study is to evaluate the feasibility and impact of Schwartz Rounds on staff well-being, compassionate care, and organizational culture, in a tertiary metropolitan hospital in Brisbane, Australia.

METHODS

This mixed methods repeated measures pilot study will recruit 24 participants in 2 groups from 2 departments, the intensive care unit and the gastroenterology department. Participants from each group will take part in 3 unit-based Schwartz Rounds. Primary outcomes will include the study and intervention feasibility measures, while secondary outcomes will include scores on the Maslach Burnout Inventory–Human Services Survey, the Schwartz Centre Compassionate Care Scale, and the Culture of Care Barometer. Primary and secondary outcomes will be collected at baseline, after the Rounds, and 3-month follow-up. Two focus groups will be held approximately 2 months after completion of the Schwartz Rounds. Descriptive statistics, paired t tests, chi-square tests, and analysis of variance will be used to compare quantitative data across time points and groups. Qualitative data from focus groups and free-text survey questions will be analyzed using an inductive thematic analysis approach.

RESULTS

The study was approved by the Mater Hospital Human Research Ethics Committee (reference number: HREC/MML/71868) and recruitment commenced in July 2021; study completion is anticipated by May 2022.

CONCLUSIONS

The study will contribute to the assessment of feasibility and preliminary efficacy of the Schwartz Rounds in a tertiary Australian hospital during the COVID-19 pandemic.

Клінічний випадок природженої CMV-нейроінфекції в дитини з вибірковим дефіцитом IgA
Authors: Maltsev D.V. , Melnik L.I. , Maltseva I.A.
Published: November 2021

Вважають, що природжена CMV-інфекція має місце щонайменше у 1 % немовлят, хоча результати останніх клінічних досліджень вказують на питому вагу зазначених уражень на рівні 8 % випадків серед усіх новонароджених. Тяжкість клінічних симптомів ураження нервової системи CMV-етіології залежить від терміну внутрішньоутробного інфікування. При ранньому інфікуванні, протягом першого триместру внутрішньоутробного періоду, коли відбувається закладка головного мозку, розвиваються тяжкі вади центральної нервової системи, включаючи аненцефалію, поренцефалію, шизенцефалію, лісенцефалію, мікрополігірію та пахігірію. При більш пізньому зараженні, протягом 2–3-го триместру вагітності, відзначають більш легкі прояви: вентрикуломегалію, порушення мієлінізації білої речовини мозку, кісти в полюсах скроневих часток, гіпогенезію мозолистого тіла, перивентрикулярні кальцифікати та ураження кохлеовестибулярних нервів. В статті наведено історію хвороби хлопчика віком 5 років з типовими клініко-інструментальними ознаками природженої CMV-інфекції. У дитини відзначались глибокий спастичний тетрапарез, тяжка затримка психомовленнєвого розвитку, рефрактерний епілептичний синдром із поліморфними нападами, порушення роботи тазових органів, унеможливлення самостійного пересування. МРТ головного мозку демонструвала типові радіологічні ознаки природженої CMV-інфекції: кортикальну атрофію, вентрикуломегалію, перивентрикулярний гліоз, поля демієлінізації в білій речовині півкуль, кісти в полюсах скроневих часток, гіпоплазію мозолистого тіла. Протягом періоду новонародженості відзначалися специфічні IgM до СMV у сироватці крові. ПЛР лейкоцитів крові виявила ДНК СMV у дитини в 5-річному віці на момент звернення в клініку за медичною допомогою. Ця інфекція призводила до генералізованої лімфаденопатії, гепатоспленомегалії, тромбоцитопенії та лімфомоноцитозу. Оцінка імунного статусу показала наявність вибіркового дефіциту IgA, з чим пов’язали розвиток цієї опортуністичної інфекції. Обговорені типові помилки при клінічному веденні дітей із природженою CMV-інфекцією та шляхи їх уникнення.
The Effects of Self-regulated Learning Strategies on Computer Programming Achievement in Teacher Education
Authors: Cheng Gary
Published: November 2021

This study investigates the effects of student use of self-regulated learning (SRL) strategies on their computer programming achievement. Ninety-six students from undergraduate teacher training programmes offered by a Hong Kong university voluntarily participated in the study. Sixty-six of them were first-year students enrolling on an introductory Java programming course, while 30 were second-year students enrolling on an advanced Java programming course. The SRL strategies adopted by participants were measured by the Motivated Strategies for Learning Questionnaire (MSLQ) and were exemplified from the reflective writing of their electronic portfolios. Their achievement in computer programming was evaluated using continuous and end of course assessments. The findings of this study suggest that higher-order cognitive strategies (i.e. elaboration, organization, critical thinking), metacognitive control strategies (i.e. self-regulation) and resource management strategies (i.e. time and study environment management, help seeking) are likely to facilitate a prolonged achievement of computer programming for both novices and non-novices. They can provide insights into designing adequate SRL strategy training to support student learning in computer programming.
Housekeeping Proteins in Meat Quality Research: Are They Reliable Markers for Internal Controls in Western Blot? A Mini Review
Authors: Zhai Chaoyu , Huff-Lonergan Elisabeth J. , Lonergan Steven M. , Nair Mahesh N.
Published: November 2021

Advancements in technology and analytical methods enable researchers to explore the biochemical events that cause variation in meat quality. Among those, western blot techniques have been successfully used in identifying and quantifying the key proteins that have critical functions in the development of meat quality. Housekeeping proteins, like β-actin, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), and tubulins are often used as internal controls in western blots to normalize the abundance of the protein of interest. However, there are increasing concerns about using housekeeping proteins for western blot normalization, as these proteins do not demonstrate any loading differences above the relatively small total protein loading amounts of 10μg. In addition, the interaction between these housekeeping proteins and programmed cell death processes highlights the concerns about using the housekeeping protein as the internal control in meat quality research. Moreover, recent proteomic research has indicated that the abundance of some housekeeping proteins, like β-actin, GAPDH, and tubulin, can be altered by preslaughter stress, dietary supplementation, sex, slaughter method, genotype, breed, aging period, muscle type, and muscle portion. Furthermore, these housekeeping proteins could have differential expression in meat with differing color stability, tenderness, and water holding capacity. Therefore, this review aims to examine the realities of using housekeeping proteins as the loading control in meat quality research and introduce some alternative methods that can be used for western blot normalization.

MILLENNIALS IN THE CREATION OF SOCIAL VALUE OF THE ENTERPRISE
Authors: Kramarenko Anna
Published: November 2021

The article emphasizes the creative activity that underlies the concept of "social value", which forms in the course of solving actual social problems. Social responsibility is mainly determined by reducing the negative impact of business on the basis of support and development of innovative projects. An analytical comparison of the categories of "social value" and "social responsibility" with the Sustainable Development Goals revealed a greater correspondence of the concept of "social value" to the sustainable development strategy. A statistical study of data from European countries allowed to draw a conclusion about the increase in social value in consumption, recycling of production resources, the use of renewable energy sources, and the growth of preferences for the development of own business. Based on the conducted research, the article highlights the exceptional role of millennials in updating the issues of social focus of business.
TARGET COSTING SUITABILITY FOR IMPROVEMENTS OF LEAN SUPPLY CHAINS
Authors: Novićević Čečević Bojana , Antić Ljilja
Published: November 2021

Competitive advantage can be seen as the superiority of some market participants to properly use resources and utilize key competencies to deliver greater value than competitors, without compromising product quality and functionality. In that sense, accounting, especially management accounting, successfully responds to managers’ needs for information that will be their adequate support in strategy implementation. Lean concept and target costing are just some of the concepts whose strategic orientation can be a good support to managers. The aim of this paper is to point out the similarities and differences between lean concept and target costing and to show on a practical example how these concepts bring business improvements in supply chain.
EFFECTUATION AND CAUSATION DECISION MAKING LOGICS OF MANAGING UNCERTAINTY AND COMPETITIVENESS BY NIGERIAN RETAIL BUSINESS ENTREPRENEURS
Authors: Ebegbetale Christopher Idemudia
Published: November 2021

Uncertainty is a major dimension of business that alters business plans and courses of actions. Hence, this study primarily examined how entrepreneurs deal with uncertainty using both effectual and causal logics. The study design was cross-sectional while multistage sampling technique was used to collect primary data. These data were analysed using bivariate correlation and hierarchical regression techniques of SPSS version 23. The results of the correlation analysis showed that causation and three of the four sub-dimensions of effectuation had significant relation with competitiveness while pre-commitment did not. The analysis further showed that Nigerian retail entrepreneurs tended more towards causation and effectuation. The results from the hierarchical regression revealed that causation made the most unique impact on competitiveness and was closely followed by experimentation and flexibility. However, affordable loss and pre-commitment did not. This study contributed to knowledge by empirically showing that entrepreneurs will not always be more effectual oriented in all cases. It also confirmed that causation and effectuation should be seen as complementary and not exclusive strategies.
SOME REMARKS ON THE CLASSICAL PRIME SPECTRUM OF MODULES
Authors: Abbasi Alireza , Naderi Mohammad Hasan
Published: November 2021

Let R be a commutative ring with identity and let M be an R-module. A proper submodule P of M is called a classical prime submodule if abm ∈ P, for a,b ∈ R, and m ∈ M, implies that am ∈ P or bm ∈ P. The classical prime spectrum of M, Cl.Spec(M), is deﬁned to be the set of all classical prime submodules of M. We say M is classical primefule if M = 0, or the map ψ from Cl.Spec(M) to Spec(R/Ann(M)), deﬁned by ψ(P) = (P : M)/Ann(M) for all P ∈ Cl.Spec(M), is surjective. In this paper, we study classical primeful modules as a generalisation of primeful modules. Also we investigate some properties of a topology that is deﬁned on Cl.Spec(M), named the Zariski topology.

The objective of the present research article is to study the $\delta$-Lorentzian trans-Sasakian manifolds conceding the $\eta$-Ricci solitons and gradient Ricci soliton. We shown that a symmetric second order covariant tensor in a $\delta$-Lorentzian trans-Sasakian manifold is a constant multiple of metric tensor. Also, we furnish an example of $\eta$-Ricci soliton on 3-diemsional $\delta$-Lorentzian trans-Sasakian manifold is provide in the region where $\delta$-Lorentzian trans-Sasakian manifold is expanding. Furthermore, we discuss some results based on gradient Ricci solitons on $3$-dimensional $\delta$- Lorentzian trans-Sasakian manifold.

Published: November 2021

A non-abelian group $G$ is called a $\CA$-group ($\CC$-group) if $C_G(x)$ is abelian(cyclic) for all $x\in G\setminus Z(G)$. We say $x\sim y$ if and only if $C_G(x)=C_G(y)$.We denote the equivalence class including $x$ by$[x]_{\sim}$. In this paper, we prove thatif $G$ is a $\CA$-group and $[x]_{\sim}=xZ(G)$, for all $x\in G$, then $2^{r-1}\leq|G'|\leq 2^{r\choose 2}$.where $\frac {|G|}{|Z(G)|}=2^{r}, 2\leq r$ and characterize all groups whose $[x]_{\sim}=xZ(G)$for all $x\in G$ and $|G|\leq 100$. Also, we will show that if $G$ is a $\CC$-group and $[x]_{\sim}=xZ(G)$,for all $x \in G$, then $G\cong C_m\times Q_8$ where $C_m$ is a cyclic group of odd order $m$ andif $G$ is a $\CC$-group and $[x]_{\sim}=x^G$, for all $x\in G\setminus Z(G)$, then $G\cong Q_8$.

TeV emissions from γ-ray bursts are very important to study their origin and the radiation mechanisms in detail. Recent observations of TeV photons in some of the GRBs are challenging to be explained by the traditional Synchrotron radiation mechanism. In this work, we present the results of a detailed investigation of the prompt and afterglow emissions of recently discovered TeV GRBs (GRB 180720B, GRB 190114C, and GRB 190829A) based on the publicly available prompt and afterglow data including 10.4m GTC and 1.3m DFOT telescopes observations of the first HESS and MAGIC bursts, respectively. Timeresolved spectroscopy of prompt emission of GRB 180720B and GRB 190114C shows an intensity tracking nature of peak energy. In the case of GRB 190829A, peak energy evolution shows a hard to soft tracking trend followed by a very soft and chaotic trend. GRB 190829A is a peculiar intermediate luminous two episodic burst with first emission episode outlier to Amati correlation. We analyzed the late time Fermi-LAT emission that encapsulates the H.E.S.S. and MAGIC observations. Some of the LAT photons are likely to be associated with these GRBs and they could have an Inverse Compton radiation mechanism.

Objective: Alzheimer's disease is characterized by progressive, irreversible brain damage and cognitive decline. Although the diagnosis and treatment of the prodromal symptoms of dementia are important, no treatment for mild cognitive impairment has been currently established. Herein, we report the case of an 80-year-old female patient with memory complaints treated with Gugijihwang-tang, a traditional Korean medicine herbal formula, as an add-on medication.Case Presentation: The patient was diagnosed with mild cognitive impairment based on clinical examinations using the Mini-Mental State Examination (MMSE), the Consortium to Establish a Registry for Alzheimer's Disease (CERAD), Activities of Daily Living (ADL) Scale, Global Deterioration (GDR) Scale, and Clinical Dementia Rating (CDR) Scale. She was treated with Gugijihwang-tang bis in die for 12 months while continuing her original medications, including 5-mg donepezil and 590-mg acetyl-l-carnitine. The MMSE score in the Korean Version of the CERAD Assessment Packet increased from 21 to 27 during the 12-month treatment period, and the CERAD 2 score increased from 33 to 62. The instrumental ADL scale score improved from 11 to 5. Other clinical examination results also showed improvement. The patient was satisfied and experienced no significant adverse events related to the Gugijihwang-tang treatment.Conclusion: This case suggests that Gugijihwang-tang could be considered as a treatment method for patients with mild cognitive impairment.
