Published: February 2022

The youth mental health crisis has become so acute during the COVID-19 pandemic that a coalition of U.S. pediatric health experts has declared it a national emergency1. To which extent this crisis can be attributed to the pandemic or the different pandemic measures is unknown. School closures are among the most heavily debated pandemic measures, with insufficient evidence on their costs2,3,4,5. We seek to narrow this blind spot, by compiling data on the manifold school closure and re-opening strategies implemented across the federal states of Germany at the onset of the pandemic and combining it with data from a nationwide, population-based, longitudinal survey on youth mental health and the largest crisis helpline for children and adolescents. We show that prolonged school closures led to a significant deterioration in youth health-related quality of life, precipitating first signs of mental health problems. Effects were most severe among boys, less mature adolescents, and families with limited living space. Young people also increasingly sought support from crisis helplines to discuss arising family and friendship problems. Importantly, the effects persist even when abstracting from the overall strain imposed by the pandemic or further pandemic measures. Indeed, school closures explain around two thirds of the aggravation of the youth mental health crisis throughout the first pandemic wave and there is no sign for a swift recovery.

Background: The objectives of this study are to assess the quality of life, levels of anxiety, and depression among Sudanese ostomates with special emphasis on sociodemographic data and ostomy-related data.Methods: This is a facility-based cross-sectional study in Khartoum state between 2018 and 2019. 100 patients participated in the study with a response rate of 80 in seven hospitals throughout Khartoum state. Standardized fecal incontinence quality of life (FIQOL) and hospital anxiety and depression scale (HADS) questionnaires were used and data obtained were analyzed by multiple statistical tests to identify any group differences and associations to the sociodemographic dataResults: Quality of life total score was found to be below the average. Depression scale scores at the average, and religious score account for the worst. While there is a strong correlation between the QOL subscales, there was no significant association between quality of life score and the sociodemographic data. Regarding anxiety and depression levels 51.3% of the participants are normal for anxiety level while 25% and 23.8% were borderline and abnormal respectively. For depression level, the score was 45% normal, 26.3% borderline and 28.8% were abnormal. neither some significant association nor subgroup differences were found regarding sociodemographic and ostomy-related data.Conclusions: Respondents had a quality of life below the average and high levels of anxiety and depression. Religious and spiritual QOL is marginally influenced by the intestinal stoma, qualitative comments also lend insight to the spiritual aspect. this finding can assist in the provision of holistic care in our stoma patients.
The effects of Fe- and Mn-oxides and imogolite in the presence of kaolinite on organic nitrogen mineralization and soil enzyme activities
Authors: Rakhsh Fatemeh , Golchin Ahmad , Nelson Paul N. , Agha Ali Beheshti Al
Published: February 2022

Clay minerals and metal oxides play an important role in controlling the decomposition of soil organic matter and the mineralization of organic nitrogen. To study the effects of clay content and composition on mineralization of organic nitrogen, an incubation experiment was carried out. In the experiment, mineralization of organic nitrogen from alfalfa residues, activities of acid and alkaline phosphatase and CM-cellulase, and microbial biomass nitrogen were measured in mixtures of sand, kaolinite (0, 15, 30 or 45%) and non-layered colloids (NLCs, being goethite, manganese oxide or imogolite at a kaolinite:NLC ratio of 1:0, 5:1 or 10:1), with pure sand as the control, which were inoculated with microbes from natural soil and incubated at 23°C in the dark at 60% of water holding capacity for 180 days. Mineralization of organic nitrogen and enzyme activity decreased, but microbial biomass nitrogen increased as the contents of kaolinite and NLCs increased. There was an inverse relationship between the specific surface area of the mixtures and the enzyme activity and mineralization of organic nitrogen. Thus, the decreased mineralization of organic nitrogen, despite an increase in microbial biomass, appears to have been due to inactivation of extracellular enzymes by adsorption to the surfaces of kaolinite and NLCs, and perhaps also decreased accessibility of organic nitrogen substrate molecules due to adsorption. The microbial biomass nitrogen increased as the water holding capacity of the mixtures increased, indicating the importance of water-filled pores for accommodating an active microbial biomass and protecting it from desiccation and predators.
Thermal performance analysis of a tilted single glazed flat plate collector considering the effect of clear sky black body temperature under different ambient conditions encountered in Delhi.
Authors: Kumar Sachin
Published: February 2022

The present study concerns with the thermal analysis of a flat plate collector covered with a single glass having a tilted surface facing south, located at Delhi (28064’ N, 77012’ E), India under different operating and climate conditions. Solar radiations falling on the tilted surface were noted throughout the year and based on the availability of these solar radiations optimum tilt angle was estimated by using empirical relation for every month of a year. The lowest optimum tilt angle was estimated for June (5.260), and the highest was estimated for December (51.950) with an overall optimum tilt angle of 31.10 for a year. The maximum variation in estimated values of UL is 11% and the collector heat efficiency factor has a maximum variation of 1.24% to 2.52%. Further, the use of the Swinbank equation provides the lower value of heat loss which in turn provides the highest value of useful heat gain and thus the efficiency is 4.596% to 9.94% higher than the efficiency calculated by using Angstrom relation which gives the lowest value of efficiency.

Authors: Braga Costa Karolina , Nejaim Yuri , Gaetti Jardim Ellen Cristina
Published: February 2022

A radiografia panorâmica (RP) é o exame de imagem mais utilizado para avaliar a relação entre as raízes do terceiro molar inferior (TMI) com o canal mandibular (CM), no entanto a tomografia computadorizada de feixe cônico (TCFC) também pode ser indicada com a mesma finalidade, tendo a vantagem de permitir uma análise tridimensional da região. O objetivo deste estudo foi realizar um levantamento bibliográfico sobre os sinais radiográficos que indicam relação de proximidade entre a raiz dentária do TMI com o CM na RP e TCFC. Buscas foram feitas no PubMed, Medline e Lilacs empregando os seguintes descritores: Radiography Panoramic, Mandibular Nerve, Molar Third, Cone-Beam Computed Tomography. Foi realizada a leitura completa dos textos compatíveis com os objetivos, excluindo àqueles em que o CM não apresentava íntimo contato com as raízes do TMI nos exames de imagens, relatos de casos clínicos e artigos que utilizaram radiográficas periapicais para observar tal relação. Os sinais radiográficos mais relevantes para avaliar a relação raiz/canal mandibular foram: interrupção da linha branca do canal, escurecimento da raiz, desvio/estreitamento do canal, bem como sinais tomográficos incluindo ausência de corticalização, posição lingual do nervo e formato anatômico do canal (lágrima e haltere), como preditores de maior risco para lesão nervosa. Conclui-se que o exame de eleição para avaliar a proximidade do TMI com o CM continua sendo a RP, tendo em vista que ela apresenta sinais confiáveis, menor dose de radiação e custo se comparado à TCFC.

Published: February 2022

Aim: The purpose of this literature review was to identify whether root traction may maintain the periodontal health of teeth with invasion of supracrestal tissue attachment and prosthetically rehabilitated. Materials and Methods: A literature review was conducted, in which the periodontal effects of root traction provided on the ability to maintain teeth with invasion of supracrestal tissue attachment and prosthetically rehabilitated were searched in the electronic databases Scopus, PubMed, Web of Science, EMBASE, Scielo and Cochrane using the Mesh descriptors "orthodontic extrusions", "forced eruption" and "crown lengthening". The inclusion criteria considered studies published in English or Spanish that presented the relationship between root traction and the effect on periodontal health in prosthetically rehabilitated teeth. After collection of articles, they were evaluated by three reviewers, who selected the studies according to their relevance according to criteria as type of study, root traction present, rehabilitation with single fixed prosthesis and period of clinical follow-up. Results: A total of 644 references were identified and after exclusion according to eligibility criteria, 33 papers covered all parameters adopted and were included in the qualitative analysis. Satisfactory prosthetic rehabilitation, associated with periodontal health after root traction, could be observed in all studies, notably with variation only in the follow-up time observed up to the first six months, 1, 2, 3 and up to 4 years. Conclusions: Root traction is a conservative and effective tool in the maintenance of periodontal health in teeth with invasion of supracrestal tissue attachment and prosthetically rehabilitated.
Role of Sb in the superconducting kagome metal CsV$_3$Sb$_5$ revealed by its anisotropic compression
Authors: Tsirlin Alexander , Fertey Pierre , Ortiz Brenden R. , Klis Berina , Merkl Valentino , Dressel Martin , Wilson Stephen , Uykur Ece
Published: February 2022

Pressure evolution of the superconducting kagome metal
CsV_33Sb_55
is studied with single-crystal x-ray diffraction and density-functional
band-structure calculations. A highly anisotropic compression observed
up to 5 GPa is ascribed to the fast shrinkage of the Cs–Sb distances and
suppression of Cs rattling motion. This prevents Sb displacements
required to stabilize the three-dimensional charge-density-wave (CDW)
order and elucidates the disappearance of the CDW already at 2 GPa
despite only minor changes in the electronic structure of the normal
state. At higher pressures, vanadium bands still change only marginally,
whereas antimony bands undergo a major reconstruction caused by the
gradual formation of the interlayer Sb–Sb bonds. Our results exclude
pressure tuning of vanadium kagome bands as the main mechanism for the
non-trivial evolution of superconductivity in real-world kagome metals.
Concurrently, we establish the central role of Sb atoms in the
stabilization of a three-dimensional CDW and Fermi surface
reconstruction.
Analysis of determining the financial inclusion index of composite, conventional and sharia banking in Indonesia
Authors: Sofilda Eleonora , Zilal Hamzah Muhammad , Mulianta Ginting Ari
Published: February 2022

In Indonesia financial inclusion remains a challenge. This study looked at how the human development index, gross domestic product, and the number of offices of banks affect the financial index in 34 Indonesian provinces for composite, conventional, and sharia banking. This study uses panel data from 2016 to 2019 to address research questions. According to the findings of this study, economic growth, human development index, regional gross domestic product per capita, and bank brances significantly influence the financial inclusion index of the composite banking. Meanwhile, economic growth, human development index, gross domestic product per capita, and the number of bank branches impact the financial inclusion index of conventional banking. However, the financial inclusion index for sharia banking shows that only economic growth variables, regional gross domestic product per capita, and the number of sharia bank branches have a significant influence. The human development index variable does not have a significant influence. Based on these findings, the Financial Service Authority (OJK) and Bank Indonesia must promote a conducive climate for increasing the financial inclusion of banking in Indonesia for both conventional and Islamic banks.
Strategy of marketing and promotion of knowledge services in university libraries from the perspective of micro media: Evidence from China
Authors: Fu Yanjun , Heyenko Mykhaylo
Published: February 2022

With the rise of micro media, the library’s traditional knowledge services and its publicity and promotion methods have been challenged. This study investigates the marketing and promotion of knowledge services through micro media in university libraries. Based on the dynamic model of knowledge service marketing promotion in university libraries, this paper conducts network research and analysis on the library knowledge service microblog, WeChat, and microfilm marketing of 42 world-class universities in China. The results show that among 42 university libraries, microblog and WeChat have a high opening rate but do not attach importance to late marketing management and maintenance (microblogs’ opening rate is 83.3%, the proportion of people paying attention is 20%). The number of knowledge service outlay exceeds 1,000 accounts (28.6%). The rate of consultation feedback within one day is 17.14%. The official WeChat account number has 97.6% of libraries. The ratio of WeChat push at least once a week is 68.3%, and the rate of consultation feedback within one day is 17.07%. Microfilm marketing is not valued as a whole (the release rate of microfilms is only 9.5%). Successful microfilm marketing (such as Tsinghua University’s “falling in love with the library” series with 7,320 views/day) helps to improve the communication efficiency of knowledge services and brand awareness. This study confirms that micro media marketing has not been fully developed and utilized. University libraries should take user experience, media technology, resource reserve, service content, account publicity, and operation as the starting point to improve user viscosity.

Authors: Warsidah Warsidah - , Muhartati Titi , Prayitno Dwi Iman
Published: February 2022

The Tembakul fish (Mudskipper) is one of the unique fauna resembling amphibian fish that can adapt to two different natural conditions. Boleopthalmus sp is one of three types of Mudskipper that inhabit the mangrove ecosystem in Mempawah. The purpose of this study was to produce fishmeal from Mudskipper Boleopthalmus sp and determine the nutritional content in the form of proximate and essential minerals based on variations in drying treatment before the flouring process. The study was carried out in November-February 2021. Samples were obtained by collecting randomly the Mempawah mangrove area and processed with five different treatments or preparations for flour processing, namely drying with salt, drying without salt, frying with oil, frying without oil, and drying with oven. Nutrient content in the form of proximate in fresh Boleopthalmus sp is fat (0.1 %), protein (20.67 %), water (81.02 %) and ash (1.69%), with phosphorus mineral content (2.06 %), calcium (1.20 %) and iron (259.16 ppm). From these five preparations for processing the fishmeal, it showed that fishmeal was processed by drying without salt before being floured with the flour yield (20 %), fat content (2.18 %), protein content (68.7%), moisture content (15.27 %), and ash content (9.17 %).
Effect of H2O2 Addition on the Photocatalyst Properties of Ag3PO4 for Methylene Blue Photodegradation
Authors: Febiyanto Febiyanto , Khoerul Amal Muhammad Sofi
Published: February 2022

In this work, a facile enhanced property of Ag3PO4 photocatalyst using H2O2 for methylene blue photodegradation has been conducted. Ag3PO4 photocatalyst was synthesized using the co-precipitation method. Then, the photocatalytic activity and stability of Ag3PO4 were tested in the methylene blue degradation under the addition of an H2O2 30% solution. According to the results, the prolonged photocatalysis reaction led to a decrease in the catalysis ability of the Ag3PO4 photocatalyst. Meanwhile, the addition of 5 mL of H2O2 (AH-10% sample) tends to enhance the stability of Ag3PO4 photocatalyst with the dye removal percentage and recycling test were up to 90.3% and three recycle runs, respectively. The low stability of Ag3PO4 might be due to the catalyst photo-corrosion through Ag+ reduction. This research suggests that H2O2 is beneficial to inhibit the photo-corrosion of Ag3PO4 photocatalyst, even though released Ag ions that were caused by the excess addition of H2O2 oxidizing agent should be considered.
Sources, enumerations and inactivation mechanisms of four emerging viruses in aqueous phase
Authors: Hossain Fahim
Published: February 2022

Emergence and re-emergence of four types of severely infectious viruses have claimed significant numbers of lives when anthropogenic activities contribute to the mutagenesis of these pathogens and infectivity of these pathogens has been noticeably altered. However, both point and non-point sources can transport these viruses in water treatment and resource recovery facilities (RRF) where the presence of these pathogens in aerosolized form or in suspension can cause astronomical public health concerns. Hence, numerous scientific studies have been reviewed to comprehend the possible inactivation mechanisms of those viruses in aqueous phase where thermal-, photo-, and chemical-inactivation have confirmed their effectiveness in restraining those viruses and inactivation mechanisms are the major focuses to apprehend the quick and cost-effective virus removal process from water and RRF. Although practical applications of nano-sized disinfectants have challenged researchers, those disinfectants can completely kill the viruses and hamper RNA/DNA replication without any sign of reactivation or repair. Moreover, limitations and future research potential are discussed so that efficacious strategic management for a treatment facility can be developed at the forefront of fighting tactics against an epidemic or a pandemic. Enumerations, besides state-of-the-art detection techniques with gene sequences, are mentioned for these viruses.
Modeling bulk surface resistance and evaluation of evapotranspiration using remote sensing and MATLAB
Authors: Shekar N. C. Sanjay , Raju B. C. Kumar
Published: February 2022

In developing countries, computation of actual evapotranspiration (AET) is challenging due to the lack of ground-based flux measurement data. The estimation of AET is crucial for water resources management involving the allocation of water for different land use/land cover (LULC) classes. The study's novelty was mapping pixel-by-pixel spatial variations of bulk surface resistance and evaluating the derived actual evapotranspiration in a sub-humid tropical river basin where flux tower data was lacking for validation. This study aimed to map bulk surface resistance and evaluate the estimated AET by global evapotranspiration data product (MOD16A2). Moderate Resolution Imaging Spectroradiometer (MODIS) data products, including land surface reflectance (LSR), land surface temperature (LST) and leaf area index (LAI) data, were used as input in MATLAB for mapping pixel-wise variations to analyze the seasonal variations in bulk surface resistance (rs) and AET in pre-monsoon and post-monsoon seasons during the years 2019 and 2012. The years 2019 and 2012 were selected because 2019 experienced a relatively wet pre-monsoon and post-monsoon, whereas 2012 experienced the opposite conditions, which proved useful when interpreting variations that are influenced by wetness conditions. Overall, the results indicated significant variability in the rs and AET for different LULC classes. MOD16A2 AET was determined to be slightly higher than the LULC classes' estimated AET. This study's MODIS satellite data products provided information on surface characteristics at a reasonable resolution. This permitted the identification of differences in LULC classes and changes in surface characteristics by season and wetness conditions, which are helpful when estimating AET.

Authors: Zhang Xianqi , Duan Bingsen , He Shaoyu , Wu Xilong , Zhao Dong
Published: February 2022

The simulation of precipitation changes can provide references for the prediction and prevention of flood disasters, and has guiding significance for the comprehensive utilization of regional water resources. Precipitation forecasting is difficult due to the randomness and uncertainty of precipitation events. CEEMD can effectively overcome modal aliasing and white noise interference. The WTD process has obvious denoising effects on the original signal. GRU can effectively solve long-term memory and reflection. Based on the advantages of problems such as gradients in propagation, a CEEMD-WTD-GRU precipitation prediction coupling model is constructed. The second decomposition of CEEMD-WTD-GRU can more effectively extract complex time series information. The time series forecasting provided a new method, which effectively improved the accuracy of the forecast and applied it to the forecast of monthly precipitation in Shanghai. The research results show that the average absolute error of the CEEMD-WTD-GRU model is 3.86, the average relative error is 3.30%, and the Nash efficiency coefficient is 0.99. The prediction accuracy is better than the CEEMD-WTD-GRU model without noise reduction, the CEEMD-LSTM model and GRU model, which shows that it has strong nonlinear and complex process learning ability in hydrological factor simulation, and can be used for regional precipitation prediction.

Desa Sukorejo di Kecamatan Bangsalsari merupakan salah satu sentra kedelai di Kabupaten Jember namun 3 tahun terakhir mengalami penurunan produksi yang disebabkan biaya produksi tidak sebanding dengan pendapatan yang diperoleh. Salah satu upaya untuk menekan biaya produksi adalah dengan menekan penggunaan pupuk kimia. Pupuk N atau pupuk urea pada pertanaman kedelai dapat diganti dengan penggunaan pupuk hayati yang dibuat dari bakteri Rhizobium spp. yang memiliki kemampuan memfiksasi Nitrogen dari udara. Program pengabdian masyarakat ini bertujuan memberikan penyuluhan dan pelatihan pembuatan pupuk N dari Rhizobium menjadi bentuk granular dan cair. Pupuk dalam bentuk granul efisien dalam aplikasinya karena tidak mudah tercuci. Pupuk dalam bentuk cair memiliki keuntungan dapat langsung diserap di perakaran dan dapat membantu merevitalisasi daya olah tanah dan mengemburkan media tanah dengan optimal. Berdasarkan hasil panen demplot yang dilakukan menunjukkan bahwa tanaman kedelai yang diberi perlakuan Rhizobium memberikan hasil yang lebih tinggi dibandingkan tanaman kedelai kontrol.

Published: February 2022

The present Cuban economic model focuses on renewable sources of energy production, according to sustainable development strategies for 2030. However, the strategies do not consider biogas (or methane) due to, among other reasons, a lack of knowledge of its actual potential. Following the methodology of the batch anaerobic digestion process, the study shows the biomethane potential contained in the most critical agricultural solid wastesgenerated in Cuba, i.e., rice straw, cane straw, corn straw, bean straw, banana straw (leaves), coffee husk, and parchment coffee. Biochemical Methane Potential (BMP) was assayed by lab-scale (585 ml) batch reactors, using the pig manure anaerobic sludge as inoculum under mesophilic conditions (35 ± 2 °C). Physicochemical parameters (total volatile solids, pH, alkalinity, volatile fatty acid concentration, and alkalinity ratio) were determined for processstability, quantifying the biogas production daily. Subsequently, the BMP was calculated for all substrates. The results showed that corn straw (0.42 l CH4 per gram of volatile solids) contained the highest biomethane potential. Stability on all systems was obtained, demonstrating the viability of the inoculum used to start digesters that treat this waste.The total potential methane obtained was 1258 106 m3/year, which is enough to generate 3,750 GWh of power per year—equivalent to 18 % of the total annual electricity generation in the country.

En el valle de Apatzingán, Michoacán, México, se cultiva la papaya (Carica papaya L.) Maradol Roja, sin embargo, al tener una producción monovarietal, los productores se enfrentan a un riesgo latente en relación con la sanidad del cultivo y la comercialización en un mercado complejo. Ante ello, el objetivo de esta investigación fue evaluar agronómicamente el desarrollo y la fructificación de tres genotipos de papaya en el ejido El Platanal, municipio de Tumbiscatio, Michoacán, México, para determinar su adaptabilidad como alternativa de producción. Las variables evaluadas fueron: altura de planta, diámetro de tallo, frutos por planta, frutos hermafroditos elongados, frutos pentandrios, altura del primer fruto y hojas por planta. El diseño experimental utilizado consistió en bloques aleatorizados, tres repeticiones por bloque (uno por genotipo) y 20 plantas por bloque con tres hileras. Las comparaciones entre medias se hicieron con la prueba Tukey (p < 0,05). Los resultados indicaron que el híbrido Siluet presentó plantas con más de 3 m de altura, la variedad Maradol Roja 2,45 m y el híbrido Amarela 2,32 m. El número total de frutos por planta difirió estadísticamente entre los genotipos: Siluet tuvo 56,93, Maradol Roja 40,82 y Amarela 34,86. La altura del primer fruto para Maradol Roja y Amarela fue de 0,86 y 0,84 m, respectivamente, los cuales resultaron estadísticamente similares. Se concluye que Maradol Roja, Amarela y Siluet comprobaron tener buen potencial de adaptabilidad a esta región, de manera que los híbridos se constituyen en materiales alternativos a la tradicional variedad Maradol Roja.

Background

Cardiovascular disorders in general are responsible for 30% of deaths worldwide. Among them, hypertrophic cardiomyopathy (HCM) is a genetic cardiac disease that is present in about 1 of 500 young adults and can cause sudden cardiac death (SCD).

Objective

Although the current state-of-the-art methods model the risk of SCD for patients, to the best of our knowledge, no methods are available for modeling the patient's clinical status up to 10 years ahead. In this paper, we propose a novel machine learning (ML)-based tool for predicting disease progression for patients diagnosed with HCM in terms of adverse remodeling of the heart during a 10-year period.

Methods

The method consisted of 6 predictive regression models that independently predict future values of 6 clinical characteristics: left atrial size, left atrial volume, left ventricular ejection fraction, New York Heart Association functional classification, left ventricular internal diastolic diameter, and left ventricular internal systolic diameter. We supplemented each prediction with the explanation that is generated using the Shapley additive explanation method.

Results

The final experiments showed that predictive error is lower on 5 of the 6 constructed models in comparison to experts (on average, by 0.34) or a consortium of experts (on average, by 0.22). The experiments revealed that semisupervised learning and the artificial data from virtual patients help improve predictive accuracies. The best-performing random forest model improved R2 from 0.3 to 0.6.

Conclusions

By engaging medical experts to provide interpretation and validation of the results, we determined the models' favorable performance compared to the performance of experts for 5 of 6 targets.
Development and Validation of the Adolescent Media Health Literacy Scales: Rasch Measurement Model Approach
Authors: Fleary Sasha A
Published: February 2022

Background

High media use has been implicated in negative social and health outcomes among adolescents. Therefore, it is critical that adolescents develop skills to healthily engage with media content. Media health literacy (MHL), skills for assessing and responding to health-related media content, and potentially targetable moderators for the relationship between media use and health-related outcomes are understudied in adolescents. The lack of MHL assessment tools may have contributed to this research gap.

Objective

This study aimed to develop and validate test-based scales of adolescents’ MHL.

Methods

The items developed were vetted iteratively via community reviews and cognitive interviews to establish content and face validity. Adolescents (N=355) completed a questionnaire that included the revised MHL items. The scales (Recognition/Identification, Influence/Critical Analysis, and Action/Reaction) were validated using Rasch measurement models. Convergent validity was assessed by correlating the summed scores of the three scales with existing functional and internet-related health literacy measures. Criterion validity was assessed by modeling logistic regressions for predicting health literacy–related behaviors from each scale after controlling for demographics. Effect sizes were estimated, and a short form was also validated.

Results

The final MHL scales (Recognition/Identification, Influence/Critical Analysis, and Action/Reaction) fit their Rasch models. The 9-item Recognition/Identification and 9-item Influence/Critical Analysis scales had good convergent validity with functional and internet-related health literacy measures and were positively related to reading instructions before taking medicines and questioning the truthfulness of health information found online. The 12-item MHL Scales-Short Form also had good convergent and criterion validity. However, convergent and criterion validity were not established for the 3-item Action/Reaction Scale.

Conclusions

The Recognition/Identification and Influence/Critical Analysis scales and the MHL Scales-Short Form may be used to determine the impact of MHL on media use and health outcome relationships and ultimately inform the development of interventions and policies to affect these relationships in multiple settings.

In an increasingly connected world and in the midst of a global pandemic, digital trials offer numerous advantages over traditional trials that rely on physical study sites. Digital trials have the potential to improve access to research and clinical treatments for the most vulnerable and minoritized, including pregnant and postpartum individuals. However, digital trials are underutilized in maternal and child health research, and there is limited evidence to inform the design and conduct of digital trials. Our research collaborative, consisting of 5 research teams in the U.S. and Australia, aimed to address this gap. We collaborated to share lessons learned from our experiences recruiting and retaining pregnant and postpartum individuals in digital trials of social and behavioral interventions. We first discuss the promise of digital trials in improving participation in research during the perinatal period, as well as the unique challenges they pose. Second, we present lessons learned from 12 completed and ongoing digital trials that have used platforms such as Ovia, Facebook, and Instagram for recruitment. Our trials evaluated interventions for breastfeeding, prenatal and postpartum depression, insomnia, decision making, and chronic pain. We focus on challenges and lessons learned in 3 key areas: (1) rapid recruitment of large samples with a diversity of minoritized identities, (2) retention of study participants in longitudinal studies, and (3) prevention of fraudulent enrollment. We offer concrete strategies that we pilot-tested to address these challenges. Strategies presented in this commentary can be incorporated, as well as formally evaluated, in future studies.
Continuous Glucose Monitoring Data Sharing in Older Adults With Type 1 Diabetes: Pilot Intervention Study

Published: February 2022

Background

Family members or friends (care partners [CPs]) of older adults with type 1 diabetes (T1DM) regularly become part of the diabetes care team, but they often lack knowledge about how to become involved to prevent hypo- and hyperglycemia. Continuous glucose monitoring (CGM) allows a person with diabetes to see their glucose levels continuously and to receive predictive alerts. A smartphone data-sharing app called the Follow app allows the person with diabetes to share continuous glucose numbers with others and to receive predictive alerts of impending hypo- and hyperglycemia. However, there are barriers to sharing this continuous glucose level data with CPs.

Objective

This study aimed to address the barriers to sharing CGM data. Our objective was to examine the feasibility of using CGM with the Follow app and a data-sharing intervention called SHARE plus in older adults with T1DM and their CPs. SHARE plus includes dyadic communication strategies, problem-solving strategies, and action planning to facilitate CGM data sharing.

Methods

Older adults with T1DM (n=20) and their CPs (n=20) received the SHARE plus intervention at baseline. People with diabetes wore the CGM for 12 weeks while sharing their glucose data using the Follow app with CPs. Feasibility data were analyzed using descriptive statistics.

Results

The SHARE plus intervention was feasible and was associated with high self-reported satisfaction for people with diabetes and their CPs as well as high adherence to CGM (mean 96%, SD 6.8%). Broad improvements were shown in the diabetes-related quality of life through the use of CGM in people with diabetes and their CPs. Although the majority of people with diabetes (11/20, 55%) were willing to share hyperglycemia data, several chose not to. The majority of people with diabetes (14/20, 70%) were willing to talk about glucose numbers with a CP.

Conclusions

Older adults with T1DM and their CPs identified having someone else aware of glucose levels and working together with a partner on diabetes self-management as positive aspects of the use of the SHARE plus intervention. Clinicians can use these results to provide data sharing coaching in older adults and their CPs.
