Authors: Aviram Eliad , Kishner Bina , Gilad David , Avraham Yoav , Schwartz Naama , Shapira Shachar
Published: June 2021

Background
Young adults may constitute a significant proportion of COVID-19 cases but generally experience a milder disease course. The goal of our study was to characterize symptoms of disease in a cohort of generally healthy young adults and to examine possible gender-associated disparities in their clinical manifestations.
Methods
The study was designed as a retrospective survey study. The study questionnaire was sent to all post-COVID-19 IDF service members between 30 June 2020 and 30 September 2020. Univariate and multivariable analysis adjusting for differences in baseline characteristics were employed in the statistical analysis.
Results
A total of 3247 questionnaires were sent. After removing duplicate submissions, a total of 792 questionnaires were included in the analysis. The average male age was 24.2 years old, and average female age was 21 years old. More than 99% of participants spent their recovery period from COVID-19 at home or in a dedicated IDF led COVID-19 Centre. Only 3 participants were hospitalized. Approximately 97% of participants reported at least one COVID-19 symptom, only 45.8% reported fever above 38.0ºC. Female participants reported significantly more symptoms of weakness, joint or muscle pain, rhinorrhea, dyspnea, sore throat, abdominal pain, nausea and vomiting and dysgeusia. Most of these differences were maintained in the multivariable analysis. Female participants also reported increased use of medications, particularly antipyretics.
Conclusions
Our findings show a high percentage of symptomatic infection with COVID-19 and suggest young generally healthy female patients experience symptoms of increased severity and duration compared to males.

Authors: Shapiro Robert E. , Sunyecz Alec , Zaslau Stanley , Vallejo Manuel C. , Crigger Chad , Dueñas-Garcia Omar F
Published: June 2021

Background

In this study, we aim to compare outcomes after cystotomy repair between standard sutures (910 polyglactin, poliglecaprone) versus barbed (V-Loc™ 90) suture. As a secondary outcome, we analyzed risk factors for suture preference between the two groups.
Methods

A retrospective chart review was undertaken for surgeries complicated by cystotomy, identified by ICD-9/10 codes from 2016 to 2019 at West Virginia University (WVU) Hospital. Comparisons were made between cystotomy repair using barbed suture versus standard braided suture. Injuries were categorized by procedure, surgeon specialty, surgical route, type of suture used in repair, and subsequent complications related to repair. Primary endpoints were examined by Pearson’s Chi-square test and interval data by t-test. A p < .05 was significant.
Results

Sixty-eight patients were identified with iatrogenic cystotomy at WVU. Barbed suture was used for cystotomy repair in 11/68 (16.2%) patients. No significant difference was seen in postoperative outcomes between patients repaired with barbed suture versus standard braided suture. Barbed suture was significantly more likely to be used for cystotomy repair in minimally invasive surgery (p = 0.001). It was most often utilized in a robotic approach 7/11 (63.6%) followed by laparoscopic 3/11 (27.3%). Body mass index (BMI) was significantly higher in patients receiving a barbed suture repair (p = .005).
Conclusion

Barbed suture is not inferior to standard braided suture for cystotomy repair and does not cause an increase in complication rate. Barbed suture offers a practical alternative to facilitate cystotomy repair in minimally invasive surgery, especially in patients with a high BMI.

Authors: Takada Ryota , Matsumoto Fumiko , Wakayama Akemi , Numata Takuya , Tanabe Fumi , Abe Kosuke , Kusaka Shunji
Published: June 2021

Purpose: The efficacies of prism adaptation test (PAT) and monocular occlusion (MO) and their optimal test durations to detect the maximum angles of deviation at near and distance in eyes with intermittent exotropia (IXT) were assessed and compared. Methods: We retrospectively reviewed the medical records of 72 patients with IXT, who had undergone the initial strabismus surgery between April 2015 and October 2018 and had been preoperatively tested by PAT and MO. The near and distance deviations measured after 30- and 60-minute PAT and MO were compared with the baseline measurements obtained immediately after prism wear and before occlusion. The measurements and the required durations for obtaining the maximum deviation angle were also compared between PAT and MO. Results: Compared with the baseline, the near deviation by PAT significantly increased after 30 (p < 0.05) and 60 (p < 0.01) minutes but not the distance deviation. Besides, the increase in the near deviation after 30 minutes was not significant. By MO, neither near nor distance deviation showed a significant difference from the baseline after 30 and 60 minutes. While the near deviations by PAT were significantly greater than those by MO at 30 and 60 minutes, a similar result was only observed at 30 minutes in the distance deviation. Conclusion: A 30-minute PAT appears to be more effective than MO in revealing the maximum angle of deviation before strabismus surgery.
Improved anticorrosive property of waterborne epoxy coating by ultrasonic blending with small amounts of polyaniline
Authors: Xu Huan-Yan , Zhang Lu , Wang Yun-Fei , Han Xu
Published: June 2021

In order to improve the anticorrosive performance of waterborne epoxy (WEP) coating, small amounts of polyaniline (PANI) were blended under ultrasonic irradiation to obtain PANI/WEP composite coatings with high dispersibility of PANI particles. The PANI/WEP composite coatings were characterized by Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM). Their adhesive force level and hardness grade were tested based on the Chinese National Standard GB/T9286-1998 and GB/T6739-1996, respectively. These results indicated that, compared to the pristine WEP coating, the addition of PANI with suitable content could completely fill the micropores or microcracks and remarkably improve the hardness grade of composite coatings. The electrochemical impedance spectra (EIS) and Tafel polarization curves revealed that the addition of PANI not only could increase the impedance arc, but also could increase the impedance modulus at low frequency. Then, the salt spray tests were employed to observe the anticorrosive performance of PANI/WEP composite coatings. Finally, the enhanced anticorrosive mechanism of WEP coating by the addition of small amounts of PANI was proposed and discussed. The addition of PANI with suitable content could play an important role of physical and chemical barriers to improve the anticorrosive performance of waterborne epoxy coating.

Published: June 2021

Background Problem Solving for Better Health ® (PSBH ® ) is a system-strengthening workshop designed to empower healthcare workers (HCWs) to solve problems. We report on the perspectives of HCWs trained in PSBH to better understand the impact and challenges of PSBH in Lesotho, a country with among the highest prevalence of HIV and tuberculosis in the world.Methods HCWs who attended PSBH workshops in 2018 – 2019 were interviewed using a semi-structured interview guide developed from a hybrid conceptual framework that captured the HCWs’ personal, interpersonal, and systemic levels of experience. Interviews were transcribed and analyzed using the framework matrix analysis method using NVivo. Results We interviewed 22 of the 86 HCWs who participated in PSBH workshops in 2018-2019. Twenty out of 22 interview participants reported that they initiated a project that was planned during the PSBH workshop. Participants reported that PSBH provided them with a new way of viewing, addressing, and solving everyday problems that can have a tangible impact on the function of healthcare facilities and the health of the community. Trainees were motivated to see the impact of their work in their jobs and in the work of subordinates as a sustained ripple effect favoring quality improvement. Participants suggested that training of district administrative leaders in PSBH would facilitate successful dissemination and help overcome the challenge of adding more work for the already-overburdened HCWs.Conclusions HCWs in Lesotho report that PSBH assists them in solving problems in their everyday work. This led the national Ministry of Health Quality Assurance Unit to request that PSBH workshops be conducted to train Ministry personnel to allow them to oversee national dissemination of PSBH, thereby fulfilling a component of the National Quality Assurance Strategic Objectives.
Vector dominance, one flavored baryons, and QCD domain walls from the "hidden" Wess-Zumino term
Authors: Karasik Avner
Published: June 2021

We further explore a recent proposal that the vector mesons in QCD have a special role as Chern-Simons fields on various QCD objects such as domain walls and the one flavored baryons. We compute contributions to domain wall theories and to the baryon current coming from a generalized Wess-Zumino term including vector mesons. The conditions that lead to the expected Chern-Simons terms and the correct spectrum of baryons, coincide with the conditions for vector meson dominance. This observation provides a theoretical explanation to the phenomenological principle of vector dominance, as well as an experimental evidence for the identification of vector mesons as the Chern-Simons fields. By deriving the Chern-Simons theories directly from an action, we obtain new results about QCD domain walls. One conclusion is the existence of a first order phase transition between domain walls as a function of the quarks' masses. We also discuss applications of our results to Seiberg duality between gluons and vector mesons and provide new evidence supporting the duality.
Organizational influence systems as a function for strategy building: An applied study in Jordanian economic sectors
Authors: Alsttar Mustafa Alsayah Abed
Published: June 2021

The study aims to identify the reasons driving internal and external entrepreneurs to use their power to produce the intended effects in organizations, and how this power affects the methods of building strategies they seek to use, based on Mintzberg’s theoretical assumptions. The research was conducted in 90 large Jordanian companies operating in finance, industry and service sectors. Data were collected from 204 managers using a questionnaire with a high degree of validity and reliability. Analysis and interpretation of the results proved that much of the organizational power held by the head of a company and top management was due to the dominance of the personal, bureaucratic, centralized and formal control systems. As a result, the classical tendency to build strategy in the planning and integrative forms was firmly established, and the participatory and democratic methods in their bargaining and adaptive forms retreated. Based on the results, the researched companies were recommended to design balanced power structures to shift the methods of strategy building from the classical tendency represented by the control of top management and external coalition to the modern tendency represented by integrating workers in democratic ways.

Authors: Wang Yu , Liu Juan-juan , Li Bao-long , Liu Wei , Zuo Yi-feng , Kong De-xing , Zhu Jia-le
Published: June 2021

To clarify the characteristics of macrobenthic assemblages and their response to the aquatic environment in the upper and middle reaches of the Heihe River, water quality, sediments and macrobenthos measurements were conducted in the summers of 2018 and 2019. The results showed that 50 species of macrobenthos were identified, belonging to 3 phyla, 7 classes, 15 orders and 32 families, mainly arthropods (37 species) and mollusks (11 species). Argyroneta aquatica, Chlaznius sp., dragonfly nymphs, Palaemon modestus, Radix auricularia, Cyraulus albus and Suecinea sp. were the dominant species in the whole study region; most of these are pollution-tolerant and moderately pollution-tolerant species. The macrobenthos density and biomass ranged from 10 to 577 ind./m2 and from 0.0907 to 50.0562 g/m2, respectively, showing high spatial heterogeneity. Predators were the main functional feeding group. One-way analysis of variance clarified that Margalef's index and the Shannon–Wiener index differed significantly among the spatial areas (P < 0.05). Canonical correspondence analysis showed that the spatial heterogeneity of the macrobenthos was affected by the water temperature and the total nitrogen and total phosphorus in sediments (P < 0.05).

Authors: You Zhaoyang , Zhao Changrong , Sun Yongjun , Zhuang Chang
Published: June 2021

To cope with the increasingly severe challenges of zinc oxide nanoparticles (ZnO-NPs) in the field of the aquatic environment, this paper uses poly-aluminum ferric chloride (PAFC) and cationic polyacrylamide (CPAM) as coagulants to enhance the removal of ZnO-NPs from water. In two environments (pure-water environment and kaolin environment) that simulate suspended solids, we studied the dosage, pH, precipitation time, and hydraulic power of ZnO-NPs at three different initial concentrations (1, 2, and 30 mg/L). The effects of various conditions on the performance of PAFC, CPAM, and PAFC/CPAM to remove ZnO-NPs were examined. Results showed that the overall removal rate of ZnO-NPs in the kaolin environment was slightly higher than that in the pure-water environment. In contrast the removal rate of ZnO-NPs in the PAFC/CPAM was significantly higher than that of PAFC or CPAM alone. The coagulation removal conditions of ZnO-NPs were optimized using a response-surface model. Under the best conditions, the removal rate of ZnO-NPs with an initial mass concentration of 30 mg/L in the PAFC/CPAM combination in pure-water and kaolin environments was 98.54% and 99.17%, respectively. Finally, by studying the changes in floc size during coagulation, enhanced coagulation was an efficient method of removing ZnO-NPs from water.

Authors: Zhao Qiang , Zhang Congcong , Tong Xiaoqiang , Zou Yunling , Li Yan , Wei Fang
Published: June 2021

Magnetite nanoparticles (Fe3O4-NPs)/orange peel (MOP) composite was prepared via one-step in-situ co-precipitation method as magnetic heterogeneous Fenton-like catalyst. The properties of MOP were characterized by scanning electron microscopy, transmission electron microscopes, Brunauer–Emmett–Teller, X-ray diffraction, Fourier-transform infrared, thermogravimetric analysis and X-ray photoelectron spectroscopy technologies. Its Fenton-like catalytic responses towards removal of methyl orange (MO) were investigated, in which the effects of initial dye concentration, pH, temperature and hydrogen peroxide dosage were studied. The MO degradation ratio up to 98.0% was obtained within 20 min in optimized conditions. The catalyst showed excellent catalytic stability exhibiting nearly 90% degradation ratio in the 10th cycle within 20 min, whereas pure Fe3O4-NPs showed only 62.5% in this stage. Due to the stabilization of complexing orange peel hydroxyl to iron oxide in the composite and its magnetic separation property, MOP composite exhibits excellent Fenton-like catalytic performance, which offers great prospects for low-cost and high-efficiency organic dye wastewater treatment.
The conditions for ensuring the social security of the population of a multiethnic region (based on the studies in the Altai Territory in 2018-2019)
Authors: Pustovalova Elena V. , Nagaytsev Viktor V. , Sterlyadeva Natalya A.
Published: June 2021

This article defines the conditions that can ensure the social security of the population of a multiethnic region in the context of the constant transformation of world socio-political and economic interactions. The authors provide a comprehensive theoretical analysis of the social security as a phenomenon characteristic of a democratic state structure. The analysis of the methodology allowed determining its potential through a system of measures implemented by the state to protect the interests of citizens; identifying a range of problems that hinder the reduction of tension in the region; summarizing experience on studying existing measures aimed at overcoming them and ensuring the possibility of self-realization of residents of the region and minimizing various risks. The results of an empirical study of the level of social tension and conflict in the Altai Territory, conducted in 2018-2019, helped to identify a number of problems that prevent the population from feeling protected from various threats associated, first of all, with dissatisfaction with the socio-economic situation and the lack of confidence in the ability of citizens themselves to influence the situation in the region. This study allowed diagnosing the need to create certain conditions aimed at ensuring the safety of the inhabitants of the region. These conditions are associated with the need to stabilize the socio-economic situation in the region by taking measures aimed at creating an attractive environment for the younger generation. It was also determined that in the region the level of trust in state bodies is reduced and the political passivity of the population is observed, which negatively affects the development of social responsibility and mutual understanding between the authorities and society. Based on the results of the study, the article formulates a number of conditions, the use of which can change the situation with the provision of social protection of the region’s population for the better.

Codonopsis pilosula Polysaccharides Alleviate Aβ1-40-Induced PC12 Cells Energy Dysmetabolism via CD38/NAD+ Signaling Pathway
Authors: Hu Yi R. , Xing San L. , Chen Chuan , Shen Ding Z. , Chen Jiu L.
Published: June 2021

Background:

Alzheimer's disease (AD) is the most common type of dementia and has a
complex pathogenesis with no effective treatment. Energy metabolism disorders, as an early pathological
event of AD,have attracted attention as a promising area of AD research. Codonopsis pilosula
Polysaccharides are the main effective components of Codonopsis pilosula, which have been
demonstrated to regulate energy metabolism.

Methods:

In order to further study the roles and mechanisms of Codonopsis pilosula
polysaccharides in AD, this study used an Aβ1-40-induced PC12 cells model to study the protective
effects of Codonopsis pilosula polysaccharides and their potential mechanisms in improving energy
metabolism dysfunction.

Results:

The results showed that Aβ1-40induced a decrease in PC12 cells viability, energy
metabolism molecules (ATP, NAD+, and NAD+/NADH) and Mitochondrial Membrane Potential
(MMP) and an increase in ROS. Additionally, it was found that Aβ1-40increased CD38 expression
related to NAD+ homeostasis, whereas Silent Information Regulation 2 homolog1 (SIRT1,
SIRT3), Peroxisome proliferator-activated receptor γ coactivator 1-α (PGC-1α) and SIRT3 activity
were decreased. Codonopsis pilosula polysaccharides increased NAD+, NAD+/NADH, SIRT3,
SIRT1, and PGC-1α related to NAD+, thus partially recovering ATP.

Conclusions:

Our findings reveal that Codonopsis pilosula polysaccharides protected PC12 cells
from Aβ1-40-induced damage, suggesting that these components of the Codonopsis pilosula herb
may represent an early treatment option for AD patients.
Risk Assessment During Longitudinal Progression of Cognition in Older Adults: A Community-based Bayesian Networks Model
Authors: Han Hongjuan , Qin Yao , Ge Xiaoyan , Cui Jing , Liu Long , Luo Yanhong , Yang Bei , Yu Hongmei
Published: June 2021

Background:

Cognitive dysfunction, particularly in Alzheimer’s disease (AD), seriously
affects the health and quality of life of older adults. Early detection can prevent and slow cognitive
decline.

Objective:

This study aimed at evaluating the role of socio-demographic variables, lifestyle, and
physical characteristics in cognitive decline during AD progression and analyzing the probable
causes and predicting stages of the disease.

Methods:

By analyzing data of 301 subjects comprising normal elderly and patients with mild cognitive
impairment (MCI) or AD from six communities in Taiyuan, China, we identified the influencing
factors during AD progression by a Logistic Regression model (LR) and then assessed the
associations between variables and cognition using a Bayesian Networks (BNs) model.

Results:

The LR revealed that age, sex, family status, education, income, character, depression, hypertension,
disease history, physical exercise, reading, drinking, and job status were significantly
associated with cognitive decline. The BNs model revealed that hypertension, education, job status,
and depression affected cognitive status directly, while character, exercise, sex, reading, income,
and family status had intermediate effects. Furthermore, we predicted probable cognitive stages of
AD and analyzed probable causes of these stages using a model of causal and diagnostic reasoning.

Conclusion:

The BNs model lays the foundation for causal analysis and causal inference of cognitive
dysfunction, and the prediction model of cognition in older adults may help the development
of strategies to control modifiable risk factors for early intervention in AD.

Authors: Wong Mabel N.K. , Lai Daniel W.L. , Chan Henry H.-L. , Lam Bess Y.-H.
Published: June 2021

Objective:

This study investigated the relationship between neural activities and retinal structures
associated with working memory (WM) in older adults with mild cognitive impairment (MCI).

Methods:

Eleven older adults with MCI and 29 healthy controls (60 to 73 years old) were tested. All
participants underwent an event-related potential (ERP) recording while performing the two-back
memory task. The Optical coherence tomography angiography (OCT-A) was administered to examine
the perfusion and vessel density in the retina.

Results:

Results showed that WM performance in the MCI group was negatively associated with ERP
latencies in central parietal regions (CP6 and CP8) (ps< 0.05). The left nasal vessel and perfusion densities
were negatively correlated with the latencies in these two central parietal regions and positively
related to WM performance only in the MCI group (ps< 0.05).

Conclusion:

The findings on WM, central parietal brain activity, and left nasal vessel and perfusion
densities in the retina help us gain a better understanding of the neural and retinal underpinnings of
WM in relation to MCI.

Authors: Chen Han-Chun , Altannavch Nyamsambuu , Zhou Xi , Khan Md. Asaduzzaman , Ahmed Ashfaque , Naranmandakh Shinen , Fu Jun-Jiang
Published: June 2021

Background:

Fomitopsis officinalis (Vill. ex Fr. Bond. et Sing) is a medicinal mushroom, commonly called
‘Agarikon’; it has traditionally been used to treat cough and asthma in the Mongolian population.

Objective:

The objective of the study was to examine the significance of biological activity of F. officinalis and evaluation
of the antioxidant activity and anticancer activity of six fractions of F. officinalis residues (Fo1-powder form dissolved
in ethanol, Fo2-petroleum ether residue, Fo3-chloroformic, Fo4-ethylacetate, Fo5-buthanolic, and Fo6-waterethanolic)
against hepatocellular carcinoma cells.

Methods:

We performed in vitro studies of cell proliferation and viability assay, annexin V-FITC/Propidium Iodide
assay, and NF-kB signaling pathway by immunoblot analysis.

Results:

Our findings revealed that all six fractions/extracts have antioxidant activity, and somehow, they exert anticancerous
effects against cancer cells. In cancerous cell lines (HepG2 and LO2), Fo3 chloroformic extract promoted
the cancer cell apoptosis and cell viability, activated G2/M-phase cell cycle, and selectively induced NF-kB proteins,
revealing as a novel antitumor extract.

Conclusion:

This study reports that Fo3-chloroformic extract is rich in antitumor activity, which was previously not
investigated in cancer. To develop the impact of F. officinalis among natural products to treat/prevent oxidative stress
disorders or cancers, further examinations of F. officinalis are needed to develop new natural drugs to treat cancer.
However, this study assessed only one extract, Fo3-chloroformic, which has a significant impact against cancer cell
lines.
An Approach on the Use of Co-sputtered W-DLC Thin Films as Piezoresistive Sensing Materials
Authors: Leal Gabriela , Furlan Humber , Massi Marcos , Fraga Mariana Amorim
Published: June 2021

Background:

Miniaturized piezoresistive sensors, particularly strain gauges, pressure
sensors, and accelerometers, have been used for measurements and control applications in various
fields, such as automotive, aerospace, industrial, biomedical, sports, and many more. A variety of
different materials have been investigated for the development of these sensors. Among them, diamond-
like carbon (DLC) thin films have emerged as one of the most promising piezoresistive
sensing materials due to their excellent mechanical properties, such as hardness and high Young’s
modulus. At the same time, metal doping has been studied to enhance their electrical properties.

Objective:

This article explores the use of co-sputtered tungsten-doped diamond-like carbon (WDLC)
thin films as microfabricated strain gauges or piezoresistors.

Methods:

Different serpentine thin-film resistors were microfabricated on co-sputtered W-DLC
thin films using photolithography, metallization, lift-off and RIE (reactive ion etching) processes.
In order to evaluate their piezoresistive sensing performance, Gauge Factor (GF) measurements
were carried out at room temperature using the cantilever beam method.

Results:

GF values obtained in this study for co-sputtered W-DLC thin films are comparable to
those reported for W-DLC films produced and characterized by other techniques, which indicates
the feasibility of our approach to using them as sensing materials in piezoresistive sensors.

Conclusion:

W-DLC thin films produced by the co-magnetron sputtering technique can be considered
as sensing materials for miniaturized piezoresistive sensors due to the following key advantages:
(i) easy and well-controlled synthesis method, (ii) good piezoresistive properties exhibiting
a GF higher than metals, and (iii) thin-film resistors formed by a simple microfabrication
process.

Исследовано влияние оптического излучения видимого диапазона на резистивное переключение в МДП-структурах ITO/ZrO2(Y)/n-Si, в том числе с наночастицами Au, встроенными в слой ZrO2(Y). Обнаружено, что зависимость ширины логического коридора резистивных состояний от интенсивности фотовозбуждения имеет пороговый характер. При увеличении интенсивности фотовозбуждения выше порогового значения наблюдалось уменьшение ширины логического коридора, предположительно, связанное с разогревом активных слоев МДП-структуры при межзонном поглощении излучения в Si-подложке. Обнаружено подавление резистивных переключений при фотовозбуждении на длине волны 650 нм (соответствующей плазмонному резонансу в наночастицах Au) за счет плазмонного оптического поглощения в наночастицах. Ключевые слова: мемристор, резистивное переключение, МДП-структуры, стабилизированный диоксид циркония, наночастицы Au, фоточувствительность.

This paper presents the results of studying the properties of InGaN layers with a high InN content (80-90%) obtained by molecular beam epitaxy with plasma activation of nitrogen on sapphire substrates with AlN / GaN buffer layers. The InGaN layers were formed using the metal modulated epitaxy (MME) method, as well as in nitrogen and metal rich conditions. It was found that the use of the MME method leads to a decrease in the density of threading dislocations in the InGaN layers. Nevertheless, despite the higher dislocation density, the smallest threshold of stimulated emission of ~ 20 kW / cm2 at 77 K was obtained for the In0.8Ga0.2N layer grown under nitrogen rich conditions, which is associated with the lowest background electron concentration in this sample (1.6•1019 cm-3).

The spontaneous synthesis of InGaN/GaN nanowires of core-shell heterostructure using molecular beam epitaxy isinvestigated in the work. It is shown by electron microscopy that a wedge-shaped crack can form at In content x=0.4 and 0.04 in the core and shell correspondent. Based on the model of internal structural stresses, a formula is proposed for estimation of the critical size and composition for the formation of cracks in NWs.The estimations and experimental data of morphology agree with each other.

Published: June 2021

Background

In 2020, the number of internet users surpassed 4.6 billion. Individuals who create and share digital data can leave a trail of information about their habits and preferences that collectively generate a digital footprint. Studies have shown that digital footprints can reveal important information regarding an individual’s health status, ranging from diet and exercise to depression. Uses of digital applications have accelerated during the COVID-19 pandemic where public health organizations have utilized technology to reduce the burden of transmission, ultimately leading to policy discussions about digital health privacy. Though US consumers report feeling concerned about the way their personal data is used, they continue to use digital technologies.

Objective

This study aimed to understand the extent to which consumers recognize possible health applications of their digital data and identify their most salient concerns around digital health privacy.

Methods

We conducted semistructured interviews with a diverse national sample of US adults from November 2018 to January 2019. Participants were recruited from the Ipsos KnowledgePanel, a nationally representative panel. Participants were asked to reflect on their own use of digital technology, rate various sources of digital information, and consider several hypothetical scenarios with varying sources and health-related applications of personal digital information.

Results

The final cohort included a diverse national sample of 45 US consumers. Participants were generally unaware what consumer digital data might reveal about their health. They also revealed limited knowledge of current data collection and aggregation practices. When responding to specific scenarios with health-related applications of data, they had difficulty weighing the benefits and harms but expressed a desire for privacy protection. They saw benefits in using digital data to improve health, but wanted limits to health programs’ use of consumer digital data.

Conclusions

Current privacy restrictions on health-related data are premised on the notion that these data are derived only from medical encounters. Given that an increasing amount of health-related data is derived from digital footprints in consumer settings, our findings suggest the need for greater transparency of data collection and uses, and broader health privacy protections.
