Accuracy of the Apple Watch Series 4 and Fitbit Versa for Assessing Energy Expenditure and Heart Rate of Wheelchair Users During Treadmill Wheelchair Propulsion: Cross-sectional Study (Preprint)
Authors: Danielsson Marius Lyng , Vergeer Melanie , Plasqui Guy , Baumgart Julia Kathrin
Published: May 2024

BACKGROUND

The Apple Watch (AW) Series 1 provides energy expenditure (EE) for wheelchair users but was found to be inaccurate with an error of approximately 30%, and the corresponding error for heart rate (HR) provided by the Fitbit Charge 2 was approximately 10% to 20%. Improved accuracy of estimated EE and HR is expected with newer editions of these smart watches (SWs).

OBJECTIVE

This study aims to assess the accuracy of the AW Series 4 (wheelchair-specific setting) and the Fitbit Versa (treadmill running mode) for estimating EE and HR during wheelchair propulsion at different intensities.

METHODS

Data from 20 manual wheelchair users (male: n=11, female: n=9; body mass: mean 75, SD 19 kg) and 20 people without a disability (male: n=11, female: n=9; body mass: mean 75, SD 11 kg) were included. Three 4-minute wheelchair propulsion stages at increasing speed were performed on 3 separate test days (0.5%, 2.5%, or 5% incline), while EE and HR were collected by criterion devices and the AW or Fitbit. The mean absolute percentage error (MAPE) was used to indicate the absolute agreement between the criterion device and SWs for EE and HR. Additionally, linear mixed model analyses assessed the effect of exercise intensity, sex, and group on the SW error. Interclass correlation coefficients were used to assess relative agreement between criterion devices and SWs.

RESULTS

The AW underestimated EE with MAPEs of 29.2% (SD 22%) in wheelchair users and 30% (SD 12%) in people without a disability. The Fitbit overestimated EE with MAPEs of 73.9% (SD 7%) in wheelchair users and 44.7% (SD 38%) in people without a disability. Both SWs underestimated HR. The device error for EE and HR increased with intensity for both SWs (all comparisons: P<.001), and the only significant difference between groups was found for HR in the AW (–5.27 beats/min for wheelchair users; P=.02). There was a significant effect of sex on the estimation error in EE, with worse accuracy for the AW (–0.69 kcal/min; P<.001) and better accuracy for the Fitbit (–2.08 kcal/min; P<.001) in female participants. For HR, sex differences were found only for the AW, with a smaller error in female participants (5.23 beats/min; P=.02). Interclass correlation coefficients showed poor to moderate relative agreement for both SWs apart from 2 stage-incline combinations (AW: 0.12-0.57 for EE and 0.11-0.86 for HR; Fitbit: 0.06-0.85 for EE and 0.03-0.29 for HR).

CONCLUSIONS

Neither the AW nor Fitbit were sufficiently accurate for estimating EE or HR during wheelchair propulsion. The AW underestimated EE and the Fitbit overestimated EE, and both SWs underestimated HR. Caution is hence required when using SWs as a tool for training intensity regulation and energy balance or imbalance in wheelchair users.
Broadening the reach of patient portals: Opportunities for self-test delivery, screening, and research (Preprint)
Authors: Lockhart Liz , Gootee Jordan , Copeland Leah , Turner DeAnne
Published: May 2024

BACKGROUND

Patient portals are widely used for patient engagement in healthcare. However, patient perspectives on using portals for research purposes, health-related screenings, and patient-initiated self-testing is under studied. It is critical to understand patient perspectives on the use of portals to expand access to care.

OBJECTIVE

To understand patient perspectives on using portals for research purposes, health-related screenings, and patient-initiated self-testing.

METHODS

Patients (N=105) from the Patient Engaged Research Center at a large, urban midwestern health system completed a 23-question online survey on patient portal (MyChart) use, willingness to use the patient portal for research-purposes, risk assessments, and self-test kits. Binomial and multinomial regressions were run to determine whether demographic characteristics were associated with how and why patients access MyChart, likelihood of completing risk assessments on MyChart, and interest in receiving self-test kits.

RESULTS

Increasing age was negatively associated with MyChart use, interest in receiving self-test kits for alcohol and illicit drug use and willingness to complete risk assessments for alcohol and tobacco use, depression, stress, anxiety, sleep, and sexual history. Race and gender were not significantly associated with willingness to answer risk assessments in MyChart.

CONCLUSIONS

The lack of significant findings based on race and gender suggests that patient portals may be an acceptable method of recruiting for and conducting research. Allowing patients to request self-test kits and complete risk assessments in portals may help patients to take agency over their healthcare. Future research should examine if patient portal recruitment may help to address persistent biases in clinical trial recruitment, to increase enrollment of women and racial minorities. Patient portals may be used for research recruitment, sending research-related information, and engaging patients to answer risk assessments, read about health information, and complete other clinical tasks.

UNSTRUCTURED

Primary care informatics (PCI) professionals address workflow and technology solutions in a wide spectrum of health, ranging from optimizing the experience of the individual patient in the clinic room to supporting the health of populations and augmenting the work of frontline primary care clinical teams. PCI overlaps uniquely with 2 disciplines with an impact on societal health—primary care and health informatics. Primary care is a gateway to health care access and aims to synthesize and coordinate numerous, complex elements of patients’ health and medical care in a holistic manner. However, over the past 25 years, primary care has become a specialty in crisis: in a post–COVID-19 world, workforce shortages, clinician burnout, and continuing challenges in health care access all contribute to difficulties in sustaining primary care. Informatics professionals are poised to change this trajectory. In this viewpoint, we aim to inform readers of the discipline of PCI and its importance in the design, support, and maintenance of essential primary care services. Although this work focuses on primary care in the United States, which includes general internal medicine, family medicine, and pediatrics (and depending on definition, includes specialties such as obstetrics and gynecology), many of the principles outlined can also be applied to comparable health care services and settings in other countries. We highlight (1) common global challenges in primary care, (2) recent trends in the evolution of PCI (personalized medicine, population health, social drivers of health, and team-based care), and (3) opportunities to move forward PCI with current and emerging technologies using the 4Cs of primary care framework. In summary, PCI offers important contributions to health care and the informatics field, and there are many opportunities for informatics professionals to enhance the primary care experience for patients, families, and their care teams.

Authors: Anderson Melissa N , C Lynall Robert , O'Connor Patrick J , Schmidt Julianne D
Published: May 2024

Aim: The relationship between post-concussion kinesiophobia and clinical and functional reaction time (RT) beyond clinical recovery remains to be elucidated. Methods: College-aged participants with (n = 20) and without (n = 20) a concussion history completed patient-reported outcomes, and RT tasks. Kinesiophobia, symptoms and RTs were compared using t-tests. Linear regressions were performed to determine if kinesiophobia predicted RT measures and dual-task cost. Results: The concussion history group reported higher scores (p < 0.01) for all patient-reported outcomes. We observed significant single-task RT differences between groups (p = 0.013) such that those without a concussion history (m = 0.51s ± 0.08) were faster (m = 0.59s ± 0.12). There were no clinical or dual-task RT differences between groups (p > 0.05). Kinesiophobia significantly predicted single-task RT (R2 = 0.22). Discussion: Kinesiophobia should be considered when measuring RT.

Published: May 2024

The usage of advertising as a medium for marketing products/services is used by various businesses to increase profits. The advertising medium mainly used is billboards, which still use fossil energy as an energy source. The Indonesian government's 2060 Net Zero Emission Program promotes using renewable energy (RE) as an energy source, such as photovoltaic (PV) as electrical energy from solar heat. As with RE, the development of PV still has problems in products and business, but PV is ready to be used as an energy source to reduce electricity bill costs. The business idea of PV installation in the advertising company sector emerged to support the government program Net Zero Emission, making advertising companies "green jobs" and absorbing human resources from vocational schools. Business conceptual design with value chains, business model canvas, and lean canvas expected can provide an overview of business opportunities with EBT for Indonesia that are environmentally friendly and energy independent.

Authors: Faysal Md. Fahim , Hossain Md. Sharif , Chowdhury Suman
Published: May 2024

This paper explores the power potentiality analysis of PV modules to monitor the output power. PV module power potentiality analysis is performed in the Bangladesh climate condition. The important factors focused in this paper are solar irradiance, cell temperature, ideality factor, clearness index, tilt angle and fill factor. P-V and I-V characteristics of PV module are observed by MATLAB simulation and the power performance on various tilt angles are investigated by the experimental set up. From the experiment, it is seen that with the change of angle the power has been changed significantly. For this reason data has been collected for a couple of days with set up of various angles of tilt. A perfect choice of tilt angle for the PV module can promote the performance to a great extent. Besides, the performance of module has been checked by MATLAB simulation taking consideration of performance factors like solar radiation, temperature, ideality factor.

Published: May 2024

A feasibility study survey held in July 2020 had tobacco farmers agreeing that there was strong need to move away from using firewood for tobacco curing. It became necessary to develop alternative renewable energy systems. Prototyping takes precedence before introducing the renewable energy tobacco curing system for use by farmers. The initiative is to design a prototype tobacco curing barn for use with solar thermal collector tobacco curing energy systems tests. The design accommodates dimensions of maximum cross-section of a tobacco leaf at 65 centimetres long and 40 centimetres wide. Prototype roof rail sustains tobacco mass of 100 kilogrammes. Barn mobility is enabled by mounting 4 roller wheels sustaining a gross weight of 500 kilogrammes. A barn handle is at one narrow side. The paper explains a detailed design process and sketches of the prototype tobacco curing barn as well as presents a lifecycle costing of the project’s investment in Zimbabwe.

Published: May 2024

ABSTRACT Energy poverty is a widespread phenomenon which is mostly attributed to the poor rural households in developing countries. This study was carried out to assess the energy poverty status and as well analyse the determinants of energy poverty among rural households in Kwara State of Nigeria thus providing information that may lead to improvement in the energy use efficiency of the rural households. A four-staged random sampling technique was used to select 150 rural households from Kwara State and were administered a well-structured questionnaire. The study employed the descriptive statistics, expenditure approach and logit regression model to identify the various energy used for cooking by the rural households, energy poverty status and the determinant of energy poverty in the study area, respectively. The result shows that the household stack the various types of energy with majority of them using the combination of modern and transitional energy types, with 59% using the traditional sources of energy and 49% using the modern sources in the past 7days. About 39% of the rural households were energy non poor, years of schooling, distance to energy source and household income significantly influence the energy poverty of the households. Although majority of the rural households spend above the energy benchmark for this study, however, majority of them uses the traditional sources of energy. The study therefore recommended necessity to establish regulatory frameworks for the protection of poor consumers to guarantee access to modern energy sources at affordable prices, which may involve the incorporation of subsidies.

Authors: Jawad Yaseen Mohammed , F. Atwan Ahmed , Ali Mohammed Khadija , Ahmed Miftah Kalthoum
Published: May 2024

This work presented a new method to extract each of the output power, efficiency, short-circuit current, open circuit voltage, and temperature of the module (Sharp type NU-JC400B), based on the values of the solar radiation falling on the horizontal surface and the maximum temperature, where the horizontal solar radiation was divided by the cosine of the angle of inclination of the module installed in the Ayn al-Tamr, zone which is equal to the latitude angle of 32.58o for this zone. The results indicated that the annual solar radiation incident in Ayn al-Tamr with the horizontal plane was 1718.33kWh/m2/year with an annual peak sun hour (solar fuel) of 4.71. Therefore, the method that we followed for predicting the performance of the solar module proved to be good and achieved results that were very close to the measured results practically, so it is suitable to be generalized as a new method for calculating the performance of any solar module.

Authors: Jahangir Mohammad Nayeem , Mia Md. Shaker , Chowdhury Suman
Published: May 2024

The research tries to observe the power difference for the PV module in the case of the partial and void of partial shading in Bangladesh. For analysis of the partial shading effect on the PV module it is necessary to establish an experiment set up for the PV module. To investigate the power output from PV module the partial shading effect has been generated using the paper coverage. The experimental result shows that the photovoltaic module can generate up to 41% more power output in the case of the void of the shading effect rather than in the shading effect. Around 50% portion of the PV module has been shaded for making partial shading effect. The other important factors influencing the output power of the PV module are solar irradiance, cell temperature; ideality factor. To get the maximum output it is essential to avoid shading effect which will help to generate more power. In this paper, MATLAB simulation of PV module has been done showing the partial shading effect under consideration of various factors like series resistance, ideality factor, temperature. Partial shading effect has been created by varying the level of solar radiation. An experiment has been carried out to see the overall performance of PV module under shading effect at a fixed tilt angle.
Three models of ecological community assembly
Authors: Alroy John
Published: May 2024

Species abundance distributions, meaning counts of individuals
apportioned among species, are fundamental patterns in ecology. Numerous
distribution models have been proposed, and most suffer from poor fit to
data, complex formulation, excessive parameterisation, or unrealistic
modelling of processes. I discuss three that meet all the basic
criteria, are easily distinguished, and stem from simple and distinct
population dynamics. The log series can be produced by assuming
taxonomically and temporally fixed turnover rates. A model derived from
scaled odds ratios assumes highly variable dynamics, and one derived
from exponential variates assumes taxonomically variable but temporally
fixed rates. Mathematical derivations are elementary. Maximum likelihood
fits to published empirical data suggest that the two new distributions
are more common in nature. Saturated models are rarely better.
Ecological communities may be assembled by processes that are easily
discerned, instead of being as mysterious as many have thought.
The effect of orthodontic bracket base shape on shear bond strength to human enamel, an in vitro study
Authors: Esmail Ziana , Wiltshire William , Pinheiro Fabio H. S. L. , Frota Carolina M. , França Rodrigo
Published: May 2024

The purpose of this study was to evaluate the in vitro effect of orthodontic bracket base shape on shear bond strength (SBS) to human enamel and assess the nature of debonding fractures using the Adhesive Remnant Index (ARI). Orthodontic brackets with different-shaped bases (flower, heart, rectangle) were bonded to 120 extracted human third molars. Shear bond strength was measured using a Servohydraulic Test System at 24 h and 2 months after bonding. Adhesive Remnant Index scores were evaluated under 10x magnification to assess the amount of resin left on the tooth. The control bracket (rectangular base shape) had the highest mean SBS (26.8 ± 8.2 megapascals [MPa]), and significantly differed from the flower (17.2 ± 4.4 MPa) and heart (18.9 ± 3.5 MPa) base shapes (p < 0.001). The mean SBS between debonding times at 24 h (21.5 ± 7.4 MPa) and 2 months (20.4 ± 6.7 MPa) were not statistically significant (p > 0.05). Analysis of ARI scores showed a significant difference between flower-24 h versus heart-2 months (p = 0.039), flower-24 h versus heart-24 h (p = 0.004), and control-2 months versus heart-24 h (p = 0.015). Bracket base shape influenced SBS, with the rectangular base shape having a higher mean SBS compared to flower and heart base shapes. Variations in ARI scores occurred based on bracket shape and were of a mixed adhesive-cohesive nature. All bracket shapes had bond strengths above the clinically acceptable range of 6–8 MPa, and may thus provide adequate SBS in a clinical situation.
Advances in Psychodermatology: Pediatric Trichotillomania
Authors: DO MS* Kelly Frasier
Published: May 2024

Trichotillomania (TTM) is a complex disease that often presents first to pediatric dermatologists. Despite its high prevalence in childhood, limited recommendations and treatment modalities are available for pediatric TTM. While Habit Reversal Therapy and Cognitive Behavioural Therapy are the most commonly used treatments for children with trichotillomania, pediatric dermatologists are more likely to prescribe medications as a primary treatment modality. Mind-skin disorders, now referred to as psychodermatologic or psychocutaneous disorders, affect the pediatric population in both a visible and psychological manner. The rise of psychodermatology in pediatric dermatology provides the opportunity to not only address any visible skin conditions such as TTM, but also any additional psychological aspects of the disorder. This review focuses on the differences in treatment modalities for children with trichotillomania utilized by pediatric dermatologists and behavioural health specialists, as well as the most recent recommendations for dermatologists and mental health providers working in conjunction with a shared goal of providing the best long-term support for these patients. Objective: Discuss the differences in treatment modalities for children with trichotillomania by pediatric dermatologists and behavioural health specialists, as well as the most recent recommendations for dermatologists and mental health providers working in conjunction with a shared goal of providing the best long-term support for these patients Raise awareness of the discrepancies that exist between pediatric dermatologists and behavioural health specialists (psychologists, mental health counsellors, school counsellors) in the treatment of trichotillomania in children Facilitate further discussion between pediatric dermatologists and behavioural health specialists when treating trichotillomania in the pediatric population.
Controlling Proteocephalus ambloplites (Cestoda) Infections and Changing Fish Parasitic Fauna Following Post-Rotenone Rehabilitation of Lakes, With Light Microscopy
Authors: Amin Omar M , Rubtsova Nataliya Y
Published: May 2024

Efforts to establish desirable fish populations by rotenone treatment of lakes dominated by winter-kill resistant species, e.g., bullhead, and restocking have been attempted by the Wisconsin Department of Natural Resources, as well as by other agencies throughout the United States since the mid-1930s. Such efforts were performed in Little Elkhart Lake, eastern Wisconsin which was treated with rotenone (1.5 ppm) in 1981, to kill its rough fish and restock with desirable fish populations. Pre- and posttreatment samples of fish were examined for parasites in September 1981 and 1988, respectively. This is a revision and update of work originally published in 1993 with the addition of light microscope images of recovered parasites for the first time. Relatively heavy infections in largemouth bass, Micropterus salmoides, (Lacépède) and sunfish in 1981 with Proteocephalus ambloplites (Leidy, 1887) (Cestoda) disappeared after the rotenone treatment. Infections with Neoechinorhynchus cylindratus Van Cleave, 1913 decreased but drastically increased with Leptorhynchoides thecatus (Linton, 1891) Kostylew, 1924 with changes in their fish and invertebrate host populations following rotenone use. Metacercariae of Posthodiplostomum minimum (MacCallum, 1921) (Trematoda) in sunfish and Hysterothylacium brachyurum Ward and Magath, 1917 (Nematoda) in largemouth bass were also present before and after the chemical treatment, respectively. The observed loss of P. ambloplites after 1981 points to a possible method for its control. The unusual presence of the leech Myzobdella lugubris in the anterior intestine of a yellow perch, Perca flavescens (Mitchill) was documented.
Caring for Epistemic Bases in the 21st Century: Paradigms of Scientific Research
Authors: Martinez Antony Paul Espiritu
Published: May 2024

The general objective of this systematic review article was to describe the care of epistemic bases in the twenty-first century: paradigms of scientific research. Method: The study used an in-depth literature review of the latest research related to the thematic axis of care-care-research in nursing, which included 23 publications in various databases, which went through a process of inclusion and exclusion criteria. Results: The act of caring has evolved considerably, transforming into a multidimensional practice that goes beyond simple physical attention and is immersed in a deep understanding of the emotional and social needs of individuals. In this context, the epistemic bases that support care in the 21st century find their foundation in the paradigms of scientific research in nursing. Conclusion: In the 21st century, nursing care is nourished by an epistemic foundation that recognizes the complexity and individuality of the health experience. Scientific research paradigms in nursing provide the conceptual framework to address care holistically, considering not only the physical, but also the emotional, social, and cultural aspects that influence people's health and well-being. This approach reflects the evolution of nursing towards a more inclusive and human-centred discipline.

Na Alta Amazônia ao sul do Solimões, entre vales, rios e cidades, observa-se uma prática contemporânea no uso da indumentária étnica por alguns grupos indígenas, em sua vida de relações urbanas e multilocais extra-aldeia, como atitude expressiva e comunicadora de múltiplos sentidos. Tal atitude compõe atualmente um contexto de deslocamentos em rede floresta-cidade-floresta, que portam dinâmicas de resistência cultural e promovem a expansão de territorialidades nativas no espaço da cidade. Neste espaço hostil, a floresta então se materializa através de corpos adornados por cores e desenhos compostos em sintaxe ininteligível ao português, desinvisibilizando o que os processos de dominação tentam apagar.

Authors: Santos Martha Daniele , Pereira Daniane , Antunes Joeli Teixeira
Published: May 2024

O objetivo deste texto é abordar o afeto seletivo nas relações educacionais como provável causa de desigualdade social através da exclusão e da evasão escolar. É de suma importância discutir as relações de omissão e naturalização de práticas excludentes no cotidiano escolar, na perspectiva de uma afetividade seletiva que pode causar a invisibilização e a evasão escolar de estudantes com deficiência e/ou situação de vulnerabilidade social. O trabalho analisa a ausência de afetividade como uma das possíveis causas para a evasão escolar. Assim, abordam-se as relações de poder estabelecidas histórica, política e culturalmente, como forma de segregação e exclusão social dentro do contexto escolar e a formação docente como potencial veículo de transgressão de ideologias de desigualdades sociais. A pesquisa reflete sobre como são afetadas as identidades dos estudantes que passam por situações de invisibilização em instituições escolares, tendo como pano de fundo o processo de acolhimento desses estudantes. Trata-se de uma pesquisa teórica de caráter bibliográfico e a metodologia aplicada consistiu-se na leitura de artigos sobre o tema, articulando com as observações feitas em espaços escolares e não-escolares. Esta pesquisa dialoga com as teorias de Piaget (1978), Vygotsky (1988, 1993, 1995), Wallon (1971, 2007, 2008) e Freire (1992, 1995, 1996, 2015), entendendo que os vínculos afetivos firmados entre educadores e educandos favorecem o desenvolvimento integral dos estudantes com e sem deficiência e contribuem para que o processo de aprendizagem ocorra satisfatoriamente.
VFT and AHP Approach to Selecting the Best Option in Decision-Making at PLN: A Case Study in the Cawang-Gandul Project
Authors: Winowoda Benaya , Wasesa Meditya
Published: May 2024

PLN EIC is one of PLN’s business units and is responsible for the development of electrical infrastructure in the working area of DKI Jakarta, Banten Province, and its surroundings. One of the national strategic projects included in the PLN is the 500 kV Cawang Baru II/Cililitan-Gandul transmission line project, with a COD target of 2026. The delay in the completion of this project and the non-fulfillment of stakeholders’ expectations will certainly have a broad impact on the operation of the electricity system, the impact on PLN’s financial performance, the social impact, the environmental impact, as well as the direct impact on the performance and image of PLN EIC. This research aims to assist management in making decisions related to the best transmission line design for the Cawang-Gandul project so that project completion can be on time and in accordance with stakeholder expectations. In this research, several methodological approaches were used to gain a broader and more complete understanding. The Problem Tree Analysis approach, combined with brainstorming and structured interview techniques, was used to explore business issues. Two complementary approaches, namely Value-Focused Thinking (VFT) and the Stakeholder Analysis method, are used to formulate stakeholder expectations and will become guidelines for formulating alternative strategies. Using a structured interview technique, 4 alternative strategies were formulated in the form of the transmission line design, namely (1) Compact Lattice Tower, (2) Underground Cable, (3) Combine Design (Compact Lattice Tower + Underground Cable), and (4) Steel Pole Tower. The next methodological approach uses the Analytic Hierarchy Process (AHP) to determine the best transmission line design, which is then analyzed using AHP Super Decision software. The results of this research show that the Underground Cable design is the best design alternative that can be implemented in the Cawang-Gandul project with several advantages, namely minimal social conflict, easy implementation, and a relatively faster work process. The final stage of research is to make an implementation plan.

Published: May 2024

This paper addresses the issue of outdoor particulate matter pollution in six North African countries-Algeria, Egypt, Libya, Morocco, Sudan, and Tunisia. Major particulate matter sources include various industries and transportation systems, dust storms, and sandstorms. It has been shown that there is a need to increase public awareness and participation and enhance capacities regarding ground-based monitoring of particulate matter, using satellite data, and assessing the health impacts of exposure to particulate matter. There is also a need for improved legislation and better governance regarding its implementation and enforcement. If possible, examples of potential impacts of particulate matter pollution on the Gross National Product (GNP) for various economic and health sectors will be reported. As outdoor particulate matter pollution is one of the major sources of loss to the GNP, air quality management needs to be strengthened.
