Published: May 2023

In the recent past, many investigations have been directed toward finding the
possible relationship between probiotic preventive-therapeutic effects and different
cancers. Among different cancers, human papillomavirus (HPV)-induced cancer is the
third most frequent cancer among women, resulting in being the second cause of death
worldwide. Current treatments, such as chemotherapy and radiotherapy, have been
shown to have some limitations, and the available effective cervical vaccines are
costly, particularly in developing countries. Therefore, the researchers seek
alternatives, such as natural components, as a new approach to treating and cure HPV-induced cancer. Among several natural components, probiotics have increasingly
gained more attention due to the probiotic-associated immunomodulation and
therapeutic efficacy shown in several studies, as well as their lower risk for human
health. In this chapter, we have reviewed the association between probiotics and
cervical cancer and discussed how probiotics could exert their effects to suppress or
even inhibit the growth of cervical tumors, preclinically or clinically. The different
aspects of probiotic application have been precisely studied to assess the potential of
probiotics in improving or treating HPV-induced cancer. In addition, the effects of
probiotics on immune responses have been described

The dependence of fishermen on obtaining income during the fishing season can cause problems in fulfilling food needs. Therefore, this study aims to analyze the food security of small-scale fishermen's households. The sampling technique was a purposive sampling of 75 small-scale fishing households. The data analysis used was Jonsson and Toole's analysis of food expenditure, energy adequacy and food security. The results showed when it is not fish season or moderate season, some fishing households do productive activities outside of fishing, such as cultivating forest land belonging to the Indonesian Forestry Minister, becoming marine tour guides, and having livestock and a working wife. As a result, household income can meet basic food and non-food expenditures. The average level of energy consumption is 2,772.8 kcal/capita/day, and the average protein consumption is 177.8 grams/capita/day. The calories from grains or rice reach 780 kcal/capita/day, and the highest protein source comes from fish getting 140.7 grams/capita/day. All fisherman household respondents have a proportion of expenditure for food consumption less than sixty per cent and a gonad maturity level of more than eighty per cent. This value indicates that all small-scale fishing households are food insecure. The existence of activities outside of catching fish diversifies business in the household, enabling fishing households to meet the basic needs of food and non-food and food security.

The parameters of even and odd crystal fields acting on iron ions in tetrahedral and octahedral positions of the Fe2Mo3O8 crystal are calculated. The obtained energy level schemes of the lowest multiplets are discussed in the context of the available experimental data. By comparing the calculated intensities of magnetic and electric dipole transitions with experimental data, the parameters of the effective Hamiltonian of the interaction of 3d electrons with an electric field are refined. It is found that the main absorption lines at T < TN in the region of terahertz frequencies are due to excitations of iron ions and are not associated with collective oscillations of magnetic moments. The splitting of absorption lines upon application of an external magnetic field is a consequence of the difference in the orientations of the magnetic sublattices relative to the crystallographic axes.
The Efficacy of a Diet Low in Fermentable Oligo-, Di-, Monosaccharides, and Polyols in Irritable Bowel Syndrome Compared to Its “Real-world” Effectiveness: Protocol for a Systematic Review
Authors: Jent Sandra , Bez Natalie Sara , Catalano Loan , Rogler Gerhard
Published: May 2023

Background

Irritable bowel syndrome (IBS) is associated with various gastrointestinal and nongastrointestinal symptoms and reduced quality of life. A diet low in fermentable oligo-, di-, monosaccharides, and polyols (FODMAPs) is one therapeutic option for IBS. Although the efficacy of the low FODMAP diet has been reported in several systematic reviews, the efficacy-effectiveness gap of the low FODMAP diet has not yet been assessed.

Objective

This systematic review aims to compare the efficacy of the low FODMAP diet from efficacy randomized controlled trials (RCTs) with the effectiveness of studies conducted in “real-world” settings.

Methods

RCTs, prospective and retrospective cohort studies, and retrospective audits assessing the low FODMAP diet in adults with IBS will be searched in 4 databases: Embase, MEDLINE, CENTRAL, and CINAHL. Two independent reviewers will perform study selection, data extraction, and risk of bias assessment and assess selected quality aspects from the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) protocol. Outcomes assessed are stool frequency, stool consistency, abdominal pain, overall symptom scores, adequate symptom relief, IBS-specific quality of life, and diet adherence. Data will be summarized with forest plots without summary statistics, tables, and narrative descriptions.

Results

The search, title and abstract screening, and full-text screening were completed in March 2021, and an updated search was done in May 2022. As of May 2023, data analysis is almost finished, and manuscript writing is in progress. Submission of the manuscript is expected by July 2023.

Conclusions

The findings of this systematic review will compare the efficacy of the low FODMAP diet for IBS found in RCTs to the diet’s real-world effectiveness.

Evaluation of the EsteR Toolkit for COVID-19 Decision Support: Sensitivity Analysis and Usability Study
Authors: Alpers Rieke , Kühne Lisa , Truong Hong-Phuc , Zeeb Hajo , Westphal Max , Jäckle Sonja
Published: May 2023

Background

During the COVID-19 pandemic, local health authorities were responsible for managing and reporting current cases in Germany. Since March 2020, employees had to contain the spread of COVID-19 by monitoring and contacting infected persons as well as tracing their contacts. In the EsteR project, we implemented existing and newly developed statistical models as decision support tools to assist in the work of the local health authorities.

Objective

The main goal of this study was to validate the EsteR toolkit in two complementary ways: first, investigating the stability of the answers provided by our statistical tools regarding model parameters in the back end and, second, evaluating the usability and applicability of our web application in the front end by test users.

Methods

For model stability assessment, a sensitivity analysis was carried out for all 5 developed statistical models. The default parameters of our models as well as the test ranges of the model parameters were based on a previous literature review on COVID-19 properties. The obtained answers resulting from different parameters were compared using dissimilarity metrics and visualized using contour plots. In addition, the parameter ranges of general model stability were identified. For the usability evaluation of the web application, cognitive walk-throughs and focus group interviews were conducted with 6 containment scouts located at 2 different local health authorities. They were first asked to complete small tasks with the tools and then express their general impressions of the web application.

Results

The simulation results showed that some statistical models were more sensitive to changes in their parameters than others. For each of the single-person use cases, we determined an area where the respective model could be rated as stable. In contrast, the results of the group use cases highly depended on the user inputs, and thus, no area of parameters with general model stability could be identified. We have also provided a detailed simulation report of the sensitivity analysis. In the user evaluation, the cognitive walk-throughs and focus group interviews revealed that the user interface needed to be simplified and more information was necessary as guidance. In general, the testers rated the web application as helpful, especially for new employees.

Conclusions

This evaluation study allowed us to refine the EsteR toolkit. Using the sensitivity analysis, we identified suitable model parameters and analyzed how stable the statistical models were in terms of changes in their parameters. Furthermore, the front end of the web application was improved with the results of the conducted cognitive walk-throughs and focus group interviews regarding its user-friendliness.
Machine Learning Model to Predict Assignment of Therapy Homework in Behavioral Treatments: Algorithm Development and Validation
Authors: Peretz Gal , Taylor C Barr , Ruzek Josef I , Jefroykin Samuel , Sadeh-Sharvit Shiri
Published: May 2023

Background

Therapeutic homework is a core element of cognitive and behavioral interventions, and greater homework compliance predicts improved treatment outcomes. To date, research in this area has relied mostly on therapists’ and clients’ self-reports or studies carried out in academic settings, and there is little knowledge on how homework is used as a treatment intervention in routine clinical care.

Objective

This study tested whether a machine learning (ML) model using natural language processing could identify homework assignments in behavioral health sessions. By leveraging this technology, we sought to develop a more objective and accurate method for detecting the presence of homework in therapy sessions.

Methods

We analyzed 34,497 audio-recorded treatment sessions provided in 8 behavioral health care programs via an artificial intelligence (AI) platform designed for therapy provided by Eleos Health. Therapist and client utterances were captured and analyzed via the AI platform. Experts reviewed the homework assigned in 100 sessions to create classifications. Next, we sampled 4000 sessions and labeled therapist-client microdialogues that suggested homework to train an unsupervised sentence embedding model. This model was trained on 2.83 million therapist-client microdialogues.

Results

An analysis of 100 random sessions found that homework was assigned in 61% (n=61) of sessions, and in 34% (n=21) of these cases, more than one homework assignment was provided. Homework addressed practicing skills (n=34, 37%), taking action (n=26, 28.5%), journaling (n=17, 19%), and learning new skills (n=14, 15%). Our classifier reached a 72% F1-score, outperforming state-of-the-art ML models. The therapists reviewing the microdialogues agreed in 90% (n=90) of cases on whether or not homework was assigned.

Conclusions

The findings of this study demonstrate the potential of ML and natural language processing to improve the detection of therapeutic homework assignments in behavioral health sessions. Our findings highlight the importance of accurately capturing homework in real-world settings and the potential for AI to support therapists in providing evidence-based care and increasing fidelity with science-backed interventions. By identifying areas where AI can facilitate homework assignments and tracking, such as reminding therapists to prescribe homework and reducing the charting associated with homework, we can ultimately improve the overall quality of behavioral health care. Additionally, our approach can be extended to investigate the impact of homework assignments on therapeutic outcomes, providing insights into the effectiveness of specific types of homework.

Published: May 2023

Background

Ultramarathon running is the most popular ultraendurance competition in terms of the number of races and runners competing annually worldwide; however, no study has compared pacing and performance over a long period.

Objective

This study analyzes the pacing of successful finishers and nonfinishers in multistage ultramarathons worldwide.

Methods

A total of 4079 athletes (men=3288; women=791) competing in 99 multistage ultramarathon events from 1983 to 2021 were analyzed, including the number of participants, age, gender, rank, and running speed of successful finishers.

Results

The results showed a significant increase in the number of events (n=338) and a significant increase in the number of finishers and nonfinishers (n=5575) in the ultramarathons worldwide during this period. The general linear models (GLMs) of pacing variation showed nonsignificant effects for gender (F1,36.2=2.5; P=.127; ηp2=0.063) and age group (F10,10=0.6; P=.798; ηp2=0.367), but it showed a significant interaction (gender × age) effect (F10,2689=2.3; P=.008; ηp2=0.009). Post hoc analyses showed that men have a higher pacing variation than women in the under 30 years (U30), U35, U45, and U50 groups. Additionally, the fastest women’s age group (U35) had the lowest pacing variation. The GLM of pacing variation by gender and event distance showed significant effects for both gender (F1,3=18.5; P<.001; ηp2=0.007) and distance (F2,3=20.1; P<.001; ηp2=0.015). Post hoc analyses showed a growing pacing variation with increasing race distance for both men and women. In addition, men had a higher variation in long events. Furthermore, there was a significant main effect for both genders (F1,3=33.7; P<.001; ηp2=0.012) and rank (F1,3=136.6; P<.001; ηp2=0.048) on performance, with men being faster than women. Pacing varied greatly due to gender (F1,3=4.0; P=.047; ηp2=0.001), with a lower (ie, more even) pacing variation for male athletes in the top 3 finishers. Male nonfinishers showed a higher performance than female nonfinishers (F1,1340=25.6; P<.001), and no difference was identified for pacing variation (F1,789=1.5; P=.228) based on gender. In addition, a weak but significant correlation (r=–0.130; P<.001) was identified between the average running speed and pacing variation for both female and male nonfinishers.

Conclusions

In summary, multistage ultramarathon competitions showed an increasing number of competitors and a higher performance challenge. Men have a higher pacing (ie, less even) variation than women, especially observed in longer events. A higher pacing variation was associated with lower performance for men, women, and nonfinishers.
How we discuss AIDS in China: mapping the AIDS Week health campaign on social media (Preprint)
Authors: Sun Haocan , Zhang Rudong , Li Xuan , Tang Kun
Published: May 2023

BACKGROUND

The potential of social media in promoting health has been widely demonstrated. However, research on the combination of social media and health campaigns in the Chinese context is limited. There is also a lack of a nationwide perspective on health campaigns. China's annual AIDS Week campaign, which uses social media for promotion, provides an opportunity for addressing this gap.

OBJECTIVE

This study aims to map the execution mechanism of China's AIDS Week policy and the characteristics of discussions by social media users in the five-year period of social context changes. The study extracts the progress and limitations of health campaigns in China over five years to provide a perspective for interventions in developing countries.

METHODS

This study uses the affordance perspective to map the discussions about AIDS on Weibo during the World AIDS Day week from November 29th to December 5th, from 2018 to 2021. Using the Latent Direct Allocation topic model, the study retrieves posts and extract key topics across the dataset. We then conducted sentiment analysis to classify expressed sentiments in the posts and performed temporal analysis to examine longitudinal trends in conjunction with the annual AIDS slogans and social environment.

RESULTS

After data cleaning, we retrieved 49,576 posts, 21 of the identified topics were coded and divided into 6 main themes: Response Methods, Specific Topics, Promotion, Virus Status, Specific Groups, and Positive Feedback. Chi-square tests revealed significant differences in sentiment distribution among themes in different years, but positive emotions were higher than negative emotions in the majority of years. Most posts did not receive any audience engagement. Additionally, audience engagement was influenced by the year's news hotspots, but not significantly correlated with the intensity or direction of sentiment. Temporal analysis revealed that news hotspots and social environment were the main factors influencing the distribution of discussion topics.

CONCLUSIONS

From 2018 to 2022, the health campaign during China's AIDS Week was designed to localize the WHO World AIDS Day. However, due to the limitations of the general public's awareness, political system, and social environment, Weibo has become a platform for reporting achievements to superiors rather than exchanging opinions with the audience. This has led to the formalization of the AIDS Week health campaign, which is highly efficient but has a limited impact. As the audience is greatly influenced by social hotspots, the execution of health campaigns should fully consider public opinion. Preachy promotion, under certain unofficial interpretations, may trigger panic and even rumors.

Authors: Chavan Prof. R. R.
Published: May 2023

Abstract: The lathe machine has two axis i.e longitudinal and transverse which are manually controlled by rotation of handwheel. This leads to error causing dimensional variation This research paper presents a real-time monitoring system for a transverse axis movement of lathe machine tool that uses a 400-pulse rotary encoder to measure the rotation of the lead screw in degrees from 0° to 360°. An Uno Arduino is utilized to set the program of the encoder shaft's rotation and the program of 360° rotation of the encoder, which is connected to the lead screw of the lathe machine through a muff coupling. When the lead screw rotates 360°, the tool moves forward by 10.20mm for a cut. Three displays are used to display the rotation of the encoder, the count of rotation, and the cut of tool. An SMPS power supply is employed to provide electrical power.

Published: May 2023

Abstract: We want to set up a system to be able to identify the indication of a heart diseases at an initial stage in order to avoid the heart failures from occurring in the first phase. A system that can precisely forecast the possibility of getting heart disease must be in place because it is unfeasible for the common individual to frequently go through pricey tests like the ECG. Researchers used a range of methods, including the feature selection algorithm sequential feature selection, LDA, SVM, RF, DT, KNN, and GBC, to predict heart illness. As a result, we recommend developing a programme that can estimate the susceptibility of a heart ailment given basic inputs like age, sex, pulse rate and pO2.

Published: May 2023

Background and objective: A deep bite malocclusion may be due to skeletal and dental factors. The analysis of the etiological factors may have an influence on the treatment plan. The aim of this study was to exploration the most common dental and skeletal factors that contribute to deep bite malocclusion in Yemeni individuals, as well as the correlations between them.
Material and methods: a cross-sectional prospective study was conducted to evaluate 136 individuals with deep bites using study casts and lateral cephalometrics (62 males and 74 females), with ages ranging from 18 to 28 years, with the Onyx program used for analysis. The recorded data was collected, tabulated, and statistically analyzed by SPSS.
Results: The Gonial angle and Jarabak index form the highest contribution to skeletal deep bite (59.3%), and the least contributing factors were the decreased saddle angle (3%), followed by decreases in the inclination angle) Pn line- PP) (11.1%). On the other hand, the most contributing dental factor to the deep bite was an exaggerated curve of spee (63.5%), followed by a decreased clinical crown length of the Lower first molar (52.6%), and the least contributing dental factor was an increased clinical crown length of the maxillary incisors. There was more correlation between skeletal factors than dental factors.
Conclusion: Deep bite malocclusion was characterized mostly by counterclockwise rotation of the mandible and increased spee curve. Understanding the most common dental and skeletal contributors will help clinicians treat patients with deep malocclusions more successfully.

Continuous-Variable Entanglement through Central Forces: Application to Gravity between Quantum Masses
Authors: Kumar Ankit , Krisnanda Tanjung , Arumugam Paramasivan , Paterek Tomasz
Published: May 2023

We describe a complete method for a precise study of gravitational interaction between two nearby quantum masses. Since the displacements of these masses are much smaller than the initial separation between their centers, the displacement-to-separation ratio is a natural parameter in which the gravitational potential can be expanded. We show that entanglement in such experiments is sensitive to initial relative momentum only when the system evolves into non-Gaussian states, i.e., when the potential is expanded at least up to the cubic term. A pivotal role of force gradient as the dominant contributor to position-momentum correlations is demonstrated. We establish a closed-form expression for the entanglement gain, which shows that the contribution from the cubic term is proportional to momentum and from the quartic term is proportional to momentum squared. From a quantum information perspective, the results find applications as a momentum witness of non-Gaussian entanglement. Our methods are versatile and apply to any number of central interactions expanded to any order.

9-Elements Uniformly Circular, Planar, and Linear Arrays Antenna Design for 5G New Radio uses Satellite Communications
Authors: Muttiah Ravandran
Published: May 2023

The study on radiation characteristics of a uniformly circular,
planar, and linear arrays antenna with linearly and centrally-fed
microstrip patch uses 9-elements arrays are analysed here. Array antenna
design plays a vital role in digital radio communications, fifth
generation mobile communications, and satellite communications. High
power transmission, reduced power consumption, enhanced spectral
efficiency, and improved communications performance are easily achieved
by using antenna arrays. Thus, the uniform circular, planar, and linear
arrays with 9-element microstrip patch arrays antenna are proposed for
fifth generation mobile communication applications. In this paper, the
proposed design of uniformly circular, planar, and linear array antenna
systems operates at 12 GHz. In parallel, wireless base stations need
azimuthally-omnidirectional antennas with sufficient power and beamwidth
in the elevation plane to cover as wide an area as possible. The design
objectives considered here are: radius of the array is quarter
wavelength and spacing between centres of arrays is the half wavelength
of centre frequency respectively. Based on the analysis of
characteristics, the performance results are demonstrated and suggested
that a uniformly circular array performs well for 5G New Radio systems.
