Effect of a Daily Collagen Peptide Supplement on Digestive Symptoms in Healthy Women: 2-Phase Mixed Methods Study
Authors: Abrahams Mariette , O’Grady Rochez , Prawitt Janne
Published: April 2022

Background

The effect of dietary collagen on managing digestive symptoms is currently lacking in the literature.

Objective

To gain a better understanding of this issue, we conducted a 2-phase mixed methods study.

Methods

Phase 1 was a mixed methods design to explore current attitude and practice among consumers and health care practitioners. The findings were used to design an 8-week phase 2 digital study called Gutme! conducted in the United States in healthy female volunteers (BMI>25 kg/m2). Our aim was, first, to determine the feasibility of conducting a fully digital mixed methods study; second, the study explored the effect of an 8-week daily supplementation of 20 g dietary collagen peptide (Peptan) on digestive symptoms. Phase 2 was a prospective, open-label, longitudinal, single-arm study. Participation involved 2 weeks of baseline tracking (digestive symptoms, mood, stool, and lifestyle) using an app, followed by 8 weeks of tracking and taking 20 g collagen peptide supplement split into 2 dosages per day. Participants were required to complete a web-based symptom questionnaire at baseline, week 2, and week 8, as well as participate in 2 scheduled video interviews.

Results

Phase 1 revealed that consumer awareness of collagen for digestive health is low (64/204, 31.4%). Among the dietitians prescribing collagen for their patients, the most common dosage was 20 g a day with notable effects after 6 weeks of intake. Within the phase 2 study, of the 40 recruited participants, 14 (35%) completed the full course of supplementation. The findings indicate that 93% (13/14) of those who completed the study experienced a reduction in digestive symptoms, which included bloating.

Conclusions

A mixed methods digital study design is feasible and acceptable for collecting relevant data in a real-life setting. The use of a 20 g daily collagen peptide supplement may reduce bloating and improve mild digestive symptoms in otherwise healthy female adults in the absence of any other dietary or lifestyle interventions.

Development of Best Practice Guidance on Online Peer Support for People With Young Onset Dementia: Protocol for a Mixed Methods Study (Preprint)
Authors: Gerritzen Esther Vera , McDermott Orii , Orrell Martin
Published: April 2022

BACKGROUND

Many people with young onset dementia (YOD) may feel isolated. Peer support has the potential to improve social health, but the inconsistent availability of age-appropriate, in-person (peer) support services for people with YOD suggests that many people with YOD miss out on the potential benefits. Online peer support could be useful, as it overcomes geographical barriers, offers a variety of options, and adjusts to various needs and preferences.

OBJECTIVE

Our study aims to develop evidence-based best practice guidance on online peer support for people with YOD and group facilitators to improve online peer support for people with YOD.

METHODS

Our mixed methods study consists of 4 phases and follows the guidelines of the Medical Research Council on complex interventions. Each phase consists of multiple substudies. The study focuses on the development stage of the Medical Research Council framework and additionally develops a plan for the feasibility/piloting, evaluation, and implementation stages. The participants are people living with YOD and peer support facilitators. The qualitative research methods include interviews, focus groups, and open questions in a web-based survey. The quantitative methods include a web-based survey consisting of existing outcome measures.

RESULTS

The study is funded by the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie Actions – Innovative Training Networks (H2020-MSCA-ITN-2018; grant agreement number: 813196), and it received ethical approval from the London Bromley Research Ethics Committee (reference number: 21/LO/0248) in April 2021. Recruitment started in May 2021. Data collection and analysis are expected to be finished by September 2022.

CONCLUSIONS

The best practice guidance can provide people with YOD with tailored and evidence-based information about online peer support, and it will be disseminated locally (in the United Kingdom) and internationally through dementia organizations, research networks, and academic institutions.

Published: April 2022

BACKGROUND

Exergames can provide encouraging exercise options. Currently, there is limited evidence regarding home-based exergaming in the post-operative phase of total knee replacement (TKR).

OBJECTIVE

This study aimed to investigate the effects of a 4-month post-operative home-based exergame intervention with an 8-month follow-up on physical functioning and symptoms among older persons undergoing TKR compared with home exercise using a standard protocol. Additionally, a concurrent embedded design of a mixed-methods study was used by including a qualitative component within a quantitative study of exergame effects.

METHODS

This was a dual-center, non-blinded, two-arm, parallel-group, randomized controlled trial with an embedded qualitative approach. One hundred patients who underwent their first unilateral TKR (age 60–75 years) were aimed to recruite. Participants were randomized to exergames or standard home exercise arms. Participants followed a progressive custom-made exergame program independently at their homes daily for four months. The primary outcomes at four months were function and pain related to the knee using the Oxford knee score questionnaire and mobility by the Timed Up and Go test. Other outcomes, in addition to physical function, symptoms, and disability, were game user experience, exercise adherence, physical activity, and satisfaction with the operated knee. Assessments were performed at the preoperative baseline and the 2nd, 4th, and 12th months post-operatively. Exergame adherence from game computers and self-reported standard exercise was followed for four months of intervention, and physical activity for 12 months using a structured diary. Qualitative data on the patients' perspectives on rehabilitation and exergames were collected through laddering interviews at 4 and 12 months.

RESULTS

The BEE-RCT was funded in 2018. Data collection started in 2019 and was completed in January 2022. The Covid-19 pandemic has caused an unavoidable situation in the study for recruitment, data collection, and statistical analysis. As of November 2020, 52 participants had been enrolled in the study. Primary results are expected to be published in spring 2022.

CONCLUSIONS

Our trial provides new knowledge on the effects of post-operative exergame intervention among older patients with TKR. Our project provides a new understanding of gamified post-operative rehabilitation, home exercise adherence, physical function, and physical activity in older adults undergoing TKR.

Authors: Ekman Björn , Thulesius Hans , Wilkens Jens , Arvidsson Eva
Published: April 2022

UNSTRUCTURED

Key informant interviews found challenges to the digitialization of health care in Sweden across areas of technical, regulatory, and patient safety and quality of care. While technical conditions are favorable, digitalization may reinforce existing inequalities. The regulatory environment is weak with several actors with unclear mandates and roles. Digital care needs to be evaluated to ensure patient safety. Enhanced availability of data may improve decision making and quality of care. The COVID-19 pandemic enhanced the role of digital care and provided a safe way to deliver services. Further analyses will expand the understanding of some of the preconditions for effective digitalization of health care.

Abstract: This research aims to study the challenges and opportunities of online footwear technology education. It focuses on the major problems faced by students while attending online classes, who are doing Footwear Design and Production courses from various footwear and fashion institutions across India. This research will also identify the best online pedagogies in footwear technology by which students can get the best understanding during their classes. It is also targeted at how students can take more interest in online classes. Before COVID-19, educational institutions of footwear technology in India were teaching through offline mode. Once the pandemic started, it challenged the education system across the world and forced educators to shift to an online mode of teaching overnight. E-learning through online classes was familiar to everyone, thus it was reimplemented with the new format. Online education has proven to be a boon for everyone who is associated with the field of education in the COVID-19 pandemic time. However, it reflects the further scope of improvement. To examine this, two separate environments were created for the same group of students. Innovative methods of online teaching were introduced. The grasping capacity of both groups was analyzed and compared. Students were approached online through the questionnaire. Various educationalists, professors, and footwear veterans have been consulted for the research. Keywords: COVID, Online Education, Innovation, Footwear Technology, E-learning
Optimized Extreme Learning Machine
Authors: Kaloni Roshan , Nayak Tejas R , Sankhe Mitanshu , Wakure Mr. Govind
Published: April 2022

Abstract: Extreme Learning Machine (ELM) is a learning method for single-hidden layer feedforward neural network (SLFN) training. The ELM strategy speeds up learning by generating input weights and biases for hidden nodes at random rather than modifying network parameters, making it much faster than the standard gradient-based approach. In this project, an ELM optimized by Hybrid Particle Swarm Optimization approach is presented to optimize the input weights and hidden biases for ELM. We will analyze and obtain results for benchmark datasets. The Optimized Extreme Learning Machine algorithm's output is compared to publicly available data. Later we will compare different algorithms and check which one gives better output metrics. Keywords: ELM, SLFN, PSO, Gradient-based approach, Optimization

Comparing ground-based and satellite data to study the spatial variability of the natural area’s thermal field (case of Kunashir island, Great Kuril ridge, Sakhalin oblast, RF)
Authors: Grischchenko M.Yu. , Mikhaylyukova P.G.
Published: April 2022

The paper deals with juxtaposing the results of the in-situ (ground-based) temperature measurements and those of temperature calculations based on TIRS thermal satellite images (Landsat 8 satellite) for Kunashir island (Great Kuril ridge). Ground measurements were recorded using iButton temperature sensors installed at a height of 1,5–2 m from the earth’s surface (including under the forest canopy), thus they fixed the air temperature. From satellite images of 100 m spatial resolution, the values of the land surface temperature (LST) were calculated through the method developed by NASA. A strict dependence of the accuracy of determining these indicators according to Landsat 8 data on the landscape features of the area was not revealed. However, the minimal values of the difference are characteristic of the areas with dense woody vegetation, and the maximal ones are confined to settlements, the vicinity of solfataric fields and economic facilities of environmental protection. As a result of the regression analysis, a good connection was established between satellite and ground measurements. The standard error was 0,95. The determination coefficient is 0,99, and it confirms the high accuracy of temperature determination using satellite images.
Um encontro entre Fiama Hasse Pais Brandão e Maria Gabriela Llansol: o processo alquímico da escrita
Authors: Dias de Faria Susanna
Published: April 2022

Fiama Hasse Pais Brandão e Maria Gabriela Llansol apresentam alguns pontos de encontro entre suas escritas, embora não haja influência direta entre elas por serem contemporâneas. Este trabalho, portanto, visa a investigar os pontos em comum do nascimento da escrita de Fiama e Llansol – como a oposição que fazem aos moldes pré-estabelecidos e a subversão da língua para que ela suporte suas experiências literárias, a metalinguagem e a alquimia (da linguagem) – utilizando como corpus trechos dos dois primeiros livros da Geografia de Rebeldes de Llansol (O livro das comunidades e A restante vida) e de alguns poemas de Fiama Hasse Pais Brandão, presentes nos livros Morfismos, Barcas novas, (Este) Rosto, Melómana, dentre outros que compõem sua Obra breve. Para alcançar tais objetivos, são considerados textos críticos e ensaísticos sobre a obra de Fiama e de Llansol, bem como textos metacríticos das autoras. Além disso, são utilizados textos sobre alquimia e textos de filósofos que se relacionam à língua e à escrita, como Nietzsche e Agamben.
Inscrever Lisboa com raios de sol e outros instrumentos agudos: a cidade na poesia de Fiama Hasse Pais Brandão
Authors: Fagundes Mônica Genelhu
Published: April 2022

Tendo partido da proposta de observar a representação de Lisboa na poesia de Fiama Hasse Pais Brandão, este artigo se desvia do objeto referencial para os modos de sua percepção, e se detém sobre uma coleção de instrumentos de que a poeta se vale para inscrever a paisagem da cidade em poesia. Unidos pelo aspecto da agudeza e por propriedades perfuro-cortantes, estes objetos materializam poeticamente o estilo (forma particular de expressão, mas também haste pontiaguda que servia à escrita dos antigos) de uma escritura esporeante, que Derrida reconheceu como um atributo do feminino: capaz de desestabilizar saberes, a um tempo rasgando e defendendo os véus de uma verdade que só se desvela à distância e como distância.
Llansol: o canto do cisne
Authors: Barrento João
Published: April 2022

O artigo propõe a leitura do último livro de Maria Gabriela Llansol, Os Cantores de Leitura, como uma grande síntese de toda uma obra, um canto do cisne em que são convocados modos de escrita particulares (o fragmento e as suas múltiplas possibilidades construtivas e expressivas), figuras de referência (o filósofo Spinoza) e uma nova ideia de comunidade trans-humana, mas não utópica. Propõem-se leituras desta última comunidade epifânica, da sua busca de uma Sabedoria do Sim, do sentido das múltiplas casas que são centros de energia viva e do lugar central da ideia do canto da leitura (do texto, do mundo e do Outro) como elemento agregador desta comunidade de vozes singulares unida pela conversação espiritual do «eterno retorno do mútuo».

A escrita feminina n’O Texto-Catarina
Authors: Branco Lucia Castello
Published: April 2022

O artigo propõe uma leitura de O Texto-Catarina, de Maria Gabriela Llansol, a partir dos pressupostos acerca da “escrita feminina”, de Lucia Castello Branco, articulados à figura llansoliana do “feminino de ninguém” e ao operador de mesmo nome, desenvolvido por Lucia Castello Branco, com base na figura llansoliana, com ressonâncias da teoria psicanalítica sobre a letra e o feminino. Busca-se investigar ainda a articulação de “feminino de ninguém” com o que Llansol teria sugerido na Carta ao Legente (2000), ao escrever: “Finalmente, eu passei apenas pela escrita. Palavra feminina como eu”. Levando em conta, segundo palavras da própria autora, que “um eu é pouco para o que está em causa”, arriscamo-nos na hipótese de que O Texto- -Catarina avança em direção ao que poderíamos chamar, com Llansol, de “escrita feminina de ninguém”. Espera-se, assim, numa leitura de Llansol e com Llansol, produzir um efeito de “sobreimpressão”, em que a relação entre afecção, imagem e pensamento se dê a ver num gesto textual ofertado também para Llansol, em reciprocidade ao que ela realiza na carta de 4 de julho de 1998, “para Lúcia Castello-Branco, e seus alunos”.

Instrument for the evaluation of higher surgical training experience in the operating theatre
Authors: Lau Kin Lun , Scurrah Rachel , Cocks Helen
Published: April 2022

Introduction Surgical trainees have to achieve a set level of operative
competence under the timeframe set by the intercollegiate surgical
curriculum. The operating theatre as the primary learning environment
needs to be conductive to achieve successful training. In this project,
we developed and validated a 27-item questionnaire which aims to
evaluate the training experience of higher surgical trainees in the
operating theatre. Methods Initial questionnaire was developed by
reviewing existing instruments. The questionnaire was then modified in a
focus group to explore themes perceived to be important to training. The
modified questionnaire was sent out to obtain the content validity index
(CVI) of each item. Lastly, the final version was disseminated and
Cronbach’s alpha was derived to measure the internal consistency of the
questionnaire. Results The Initial version of 33 questions was modified
in focus group into a 29-item 4-point Likert scale questionnaire
covering three areas. 14 responses were received from higher surgical
trainee and consultants to determine the CVI. 27 out of 29 items reached
the threshold index of 0.87. Finally, the 27-item questionnaire achieved
a Cronbach’s alpha of 0.88 from 17 responses. Discussion The Cronbach’s
coefficient of 0.89 in the resultant questionnaire is comparable to
other existing medical education evaluation tools, which indicates a
high internal consistency. Our validated questionnaire can be utilized
to identify areas that needs to be improved as perceived by higher
surgical trainees and to improve their training experience in theatre.

model description of this process in the ‎form of a dynamical system. In
recent years, block-oriented models have been widely used to ‎model
non-linear systems. The Wiener-Hammerstein model consists of two linear
dynamic ‎blocks, with a nonlinear static block between them. In the
simulations, different types ‎of systems were identified by the proposed
Weiner-Hammerstein ‎model, which was optimized using a genetic
algorithm. This approach is concerned with the ‎estimation of a
photovoltaic (PV) system based on observed data. The nonlinear input and
output ‎are taken from the irradiance and DC output current data of the
real system, respectively. The ‎simulation results revealed the
effectiveness and robustness of the proposed ‎model using a genetic
algorithm. The simulation results show an MSE value of ‎0.000774‎ for
‎normal operation of the PV system‎ and ‎0.009863‎ for the shading
effect‎ between the estimated ‎and reference information rates.‎
Reconfigurable band pass filter based on DMTL structure
Authors: Ganesh G.V. , M .Lakshman Kumar
Published: April 2022

This paper presents the design and optimization of CPW (coplanar
waveguide) based tunable band pass filter by using RF MEMS capacitive
switches and distributed MEMS transmission line (DMTL). To achieve
tunability we have used Twelve MEMS capacitive type switches (six
fixed-fixed types and six cantilever type). The center frequency and
bandwidth tunability can be achieved by actuating shunt (fixed-fixed)
and series (cantilever type) switches respectively. Tunable filter
performance is mainly depending on the switches individual performance.
Actuation voltage, return loss, insertion loss are the basic performance
parameters of any RF MEMS switch. Electromechanical and RF performance
analysis of the switches are initially carried out to analyze the
performance without integrating with the DMTL structure. The designed
shunt and series switches require 15 and 22V respectively to reach the
beam 2/3 of the initial gap. Electro-mechanical analysis of the switches
is carried out for different conductor materials, dielectric materials,
different beam widths, different dielectric thickness values, and
different air gap vales. After integration of the switches with DMTL
structure to get the optimized filter a detailed electromagnetic
analysis of various parameters and materials are done. Simulation
results shows that return loss and insertion loss is improved by using
this structure. The center frequency of the filter has the variation
from 0.2-1 GHz with band pass return loss of -22.5dB. The band width
tuning of nearly 0.7 GHz with band pass insertion loss of -3dB is
achieved.

Published: April 2022

Objective: This study evaluates the benefits and limitations of selected
modalities of digital image enhancement in detection of cholesteatoma
remnants during endoscopic ear surgery (EES) and compares their
usefulness in recognizing residual disease. Study Design:
Cross-sectional study Setting: Tertiary referral hospital Methods: A
total of 10 questionnaires of 18 intraoperative pictures with equal
numbers of cholesteatoma and non-cholesteatoma images, each presented in
three different image enhancing modalities (clara, spectra A, spectra
B), were generated. Fifty-one experienced ear surgeons participated in
the survey and were randomly assigned to a questionnaire and completed
it at two time points. The experts were asked to rate for each picture
whether cholesteatoma was present or not. Results Clara showed the
highest accuracy in cholesteatoma detection, followed by spectra A and
lastly spectra B. In contrast, spectra B showed the highest sensitivity
and clara the highest specificity, while spectra A was placed in the
middle for both values. Using the spectra B modality, most responses
agreed across the two time points,. Ear surgeons assessed the
usefulness, as well as preference among image modalities in the
following order: clara, spectra B, spectra A. Conclusion The suitability
of image enhancement techniques for application in EES could be shown.
Clara can be considered the state-of-art technique throughout the
procedure and has subjectively been evaluated best by surgeons. Due to
its high sensitivity, spectra B is recommended regarding the final check
after resection to prevent cholesteatoma residuals.
The impact of diagnostic method on sense of control and powerlessness and social support in endometriosis patients — A retrospective cohort study
Authors: Hanly Ciara , Leonardi Mathew , Eathorne Allie , Armour Mike
Published: April 2022

Objectives: To determine the impact of the diagnostic test method
(clinical, diagnostic imaging, or diagnostic laparoscopy) of
endometriosis on the individual’s sense of control over their disease
and their perceived access to social supports. Design: Retrospective
cohort study. Setting: International. Population: 1,634 people aged
18-55 who had received a diagnosis of endometriosis. Methods: This study
reports on data collected by the validated Endometriosis Health
Profile-30 (EHP-30) section of a larger survey conducted between May and
July 2020. Participants were recruited by social media platforms. Scores
on the dimensions of interest were analysed with diagnostic method as
the variable of interest. Diagnostic method proportionality was also
assessed as a secondary outcome by geographical region. Main Outcome
Measures: Scores on the dimensions of control and powerlessness
and social support on the EHP-30. Results: There was a difference
between control and powerlessness scores for patients that
received a diagnosis via imaging (ultrasound/magnetic resonance imaging)
versus clinical diagnosis (P=0.049). However, this did not reach
significance when co-variates were controlled for (P=0.054). No other
comparisons between diagnostic method and EHP-30 scores demonstrated a
difference. There was a statistically significant (P<0.0001)
difference in the rate of utilization of the various diagnostic imaging
techniques between geographical regions with diagnostic imaging being
relatively uncommon and surgery being the most common method of
diagnosis. Conclusions: The diagnostic method of endometriosis does not
appear to have a clinically significant impact on an individual’s sense
of control over their disease nor their access to social supports.
Note on some classes of holomorphic functions related to Jack’s and Schwarz’s lemma
Authors: Mateljevic M. , Mutavdzic N. , Örnek B.N.
Published: April 2022

In this paper we discuss holomorphic mappings f of the unit disc U and
corresponding index defined as If (z) = zf?(z) f(z). We are interested in
finding bounds on the growth of functions f and related issues, if there are
known some properties of If on U. Our main tool in accomplishing this
connection is Jack?s lemma. As a special case, we got estimates on the
growth of some classes of ?-starlike functions as well as some interesting
generalisations.
España como polo formativo de científicos sociales del Sistema Nacional de Investigadores en el noreste de México
Authors: Mejía González Rubén
Published: April 2022

El objetivo de esta investigación fue analizar a España como polo formativo doctoral de científicos sociales del Sistema Nacional de Investigadores (SNI), en concreto para quienes radican en el noreste de México, e identificar patrones más específicos por instituciones de formación y de adscripción, por disciplina y de nivel de reconocimiento dentro del sistema. Para ello, se utilizó una metodología cuantitativa para contabilizar y realizar un análisis de proporciones de los miembros del Área V (correspondiente a ciencias sociales) del padrón del SNI para los estados de Coahuila, Nuevo León y Tamaulipas. Los hallazgos muestran que España es el polo de formación extranjera cuantitativamente más importante, más marcadamente en las universidades públicas estatales. También existe una tendencia de estudiar en ciertas universidades españolas para disciplinas como ciencias económicas o sociología. Por otra parte, se observa que estos científicos sociales con doctorados en España han recibido un reconocimiento mayor en el SNI al de los doctorados en México, pero por debajo del promedio de los graduados en otros países extranjeros. De esta forma, los resultados obtenidos muestran a España como el polo formativo más importante en el campo de las ciencias sociales en la región, pero sin que la mayoría de los investigadores formados en este país alcancen el nivel de reconocimiento que los formados en otros países con mayor tradición científica.

Theory of Planned Behavior in predicting condom use in Latin-American Women
Authors: Enríquez-Negrete David Javier , Sánchez-Medina Ricardo , Bárcena-Gaona Susana Xóchitl , Chávez-Santos Itzel Guadalupe
Published: April 2022

Background: The theory of Planned Behavior (TPB) is used to predict condom use. The present study assessed the causal relationships of the TPB in a cultural context different from the one that was proposed. Objective: To assess the causal relationships among the variables proposed by the TCP to determine if they predict consistent condom use in two groups of Latina women and to identify the inter-group similarities in both groups and the discrepancies with what the model proposes for the North American population. Method: A set of variables were evaluated in two samples of Latina women (Mexican and Argentine): consistency of condom use, intention to use condoms in the next sexual encounter, the subjective norm of friends and parents, attitudes towards condoms, and perceived behavioral control to use condoms. We used the Linear regression analysis. Results: Intention to use condoms was found to be the best predictor of condom use. Subjective norm was more important than attitudes; although the latter variable was not configured as a predictor in Argentine women. Conclusion: The associations between the CTP variables and the predictive values of the variables may change according to the cultural group evaluated; perceived behavioral control, in both samples, was not a direct predictor of condom use behavior, but it was a predictor of intention to use condoms. In addition, we discussed the relevance of the variables proposed by the TCP about the cultural context of Latinos and the critical use of the model in populations other than North America.
