Investigating the Relationship Between Metabolic Syndrome with Physical Activity and Eating Habits: The Result of the Tabari Cohort Study

Background: Metabolic syndrome (MetS) is a group of metabolic issues that increase the risk of type 2 diabetes and heart disease. Objectives: To reduce deaths from type 2 diabetes and heart disease, this study was conducted to determine the relationship between metabolic syndrome, physical activity, and eating habits in participants of the Tabari cohort study. Methods: In this descriptive cross-sectional study, data from the Tabari cohort in an urban and mountain area in Sari, Mazandaran, was utilized from June 2015 to November 2017. Background information of participants was documented, and their eating habits were assessed using a food habit questionnaire. Additionally, the physical activity levels of the participants were recorded. All individuals were assessed for metabolic syndrome according to the third Adult Treatment Panel (ATP III) guidelines. The gathered data was then inputted into SPSS V.23 software for analysis. Qualitative variables, such as demographic and epidemiological data, were compared between the two groups using the chi-square test, while quantitative variables were compared using an independent t-test. Results: A total of 10,255 adults between the ages of 35 and 70 participated in this study, and after applying entry and exit criteria, 9,976 people, including 4,083 with metabolic syndrome and 5,893 healthy individuals, were included in the final analysis. There was no significant difference in the average Body Mass Index (BMI) between individuals with metabolic syndrome (30.6 ± 4.5 kg/m²) and healthy individuals (26.8 ± 4.4 kg/m²). However, individuals with metabolic syndrome exhibited significantly higher values for height, weight, waist circumference, abdominal circumference, and wrist circumference compared to the control group (P = 0.001). The average Metabolic Equivalent of Task (MET) for the entire population was 43.03 ± 9.27, with a median of 40.68 (range: Twenty-four-one hundred three) hours/day. A greater percentage of individuals with metabolic syndrome (57.0%) and healthy individuals (45.2%) had MET values below the average (P = 0.001). Regarding energy intake, individuals with metabolic syndrome consumed an average of 2189.74 ± 721.90 calories, while healthy individuals consumed 2354.92 ± 4.04 calories, showing a significant difference (P = 0.006). Moreover, healthy individuals demonstrated significantly higher consumption of added salt in food, fried foods, fried potatoes, fried onions, fried vegetables, and various types of cooking oils compared to those with metabolic syndrome (P = 0.001). Conclusions: Based on the results of the Tabari cohort study, the prevalence of metabolic syndrome in Mazandaran was 41.10%, highlighting the need for prevention and screening programs. In this study, individuals with metabolic syndrome consumed fewer fried foods, trans fats, and daily calories compared to the healthy group. Considering that this study is cross-sectional and utilized data from the Tabari cohort, it is assumed that the difference is due to dietary compliance and lifestyle changes in patients with metabolic syndrome. It is recommended that prospective studies be designed to evaluate the causes of differences in metabolic syndrome components between the two groups.

Repurposing prescribed hydromorphone: Alternative uses of safer supply and tablet-injectable opioid agonist treatment to meet unaddressed health needs

BackgroundIn response to the ongoing overdose crisis in Canada, a number of opioid agonist treatment and safer supply programs provide people at high overdose risk with daily-dispensed tablet hydromorphone, with some requiring witnessed ingestion and others providing take-away doses. While these programs are intended to reduce overdose events by limiting people's use of the contaminated drug supply, the experiences of people receiving hydromorphone vary. In this article we explore the ways people repurpose hydromorphone to address unmet needs. MethodsThis article draws on in-depth qualitative interviews from two studies evaluating hydromorphone tablet distribution programs in British Columbia, Canada. We used thematic analysis to identify themes related to repurposing hydromorphone. We compared themes across the two studies to identify any similarities or differences in relation to the ways study participants discussed repurposing hydromorphone tablets. We utilize vignettes – snapshots of participant experiences – to analyse and represent the data. ResultsFour vignettes demonstrate how hydromorphone tablets are often being used to address and resolve unmet needs of people who use drugs. While most participants reported reducing their use of illicit drugs, a variety of instrumental uses of tablet hydromorphone were also discussed, including reducing anxiety, addressing sleep issues, withdrawal management, and managing chronic pain. ConclusionOur findings demonstrate how people who use drugs are maximizing the benefits of tablet hydromorphone distribution to address unmet needs. Hydromorphone distribution programs represent a public health and harm reduction intervention that is usefully addressing experiences related to structural vulnerabilities (such as inadequate pain management), which are often overlooked amongst stigmatized groups.

Complementary and integrative medicine in cancer-related fatigue

The majority of cancer patients experience fatigue during the course of their illness. Fatigue should not be seen as an inevitable consequence of cancer and its treatment. Cancer-related fatigue (CRF) is amultidimensional symptom complex that is influenced by avariety of factors. Complementary medicine approaches offer potentially promising strategies to address this fatigue and can therefore be avaluable addition to conventional therapies.In this narrative review, complementary medicine treatment approaches for tumor-associated fatigue are presented according to the historical development and current scientific evidence. The focus is on methods with the highest current evidence based on the recommendations of national and international guidelines. Therapeutic approaches from mind-body medicine, such as mindfulness-based stress reduction (MBSR), mindfulness-based cognitive therapy (MBCT), yoga, tai chi, and qigong, as well as acupuncture, acupressure, moxibustion, and phytotherapeutic treatment approaches are presented.In Germany, the complementary therapies listed here are not generally covered by health insurances. However, afew clinics have developed comprehensive programs in mind-body medicine, for which cost coverage has already been obtained. As aresult, complementary medical treatments for cancer-related fatigue that adhere to national and international guidelines are typically available only as private services or within the framework of study participation.

Parental Perceptions of Community and Professional Attitudes Toward Autism.

The purpose of this study was to examine parent perceptions of professional and community attitudes about autism through the lens of parenting their autistic children from birth through adulthood. Implications of this research may assist with future development and study of professional and community supports of individuals on the autism spectrum and their families. The study participants consisted of 51 parents who had an adult-aged child on the autism spectrum. One-on-one interviews were conducted with parents about their experiences raising a child with autism. Data were double-coded and analyzed using a qualitative, phenomenological approach to explore parents' experiences with and perceptions of society members' attitudes towards autism. Positive and negative themes were identified across parents' perceptions of professionals and of community members. Themes regarding professional attitudes included cooperating with family requests, presuming competence of individuals with autism, complacency towards the needs of families and individuals with autism, and discrimination towards the individual with autism based on age or level of need. Themes regarding community member attitudes included valuing the strengths of individuals with autism, accommodating autistic differences, intolerance of autistic traits, and prejudice towards individuals with autism. Findings indicate that professional and community members presented with both positive and negative attitudes towards autism and individuals on the autism spectrum, with negative attitudes proving more prevalent in parent recollections. Results suggest a need for further research and related training to improve interactions with and support of individuals with autism and their families.

Characterizing visual field loss from past mercury exposure in an Indigenous riverine community (Grassy Narrows First Nation, Canada): a cluster-based approach

BackgroundBetween 1962 and 1975, a chlor-alkali plant in Canada discharged approximately 9 metric tons of mercury (Hg) into the Wabigoon River. Over the following decades, biomarkers of Hg exposure of persons from Grassy Narrows First Nation (Asubpeeschoseewagong Anishinabek), located downriver from the discharge, reflected Hg concentrations in fish. Hg exposure is known to target the calcarine fissure, resulting in visual field (VF) loss. Most studies and clinical reports focus solely on peripheral VF loss; little is known about the impact of Hg on the central and paracentral portions. The present study sought to characterize the patterns of VF loss with respect to past and current Hg.MethodsA 28-year hair-Hg (HHg) database, created from a 1970–97 government biomonitoring program, served to select study participants with ≥ 4 year-based HHg measurements (n = 81). Blood-Hg was assessed for current exposure. Light sensitivity thresholds across the VF were analyzed monocularly, using a Humphrey Field Analyzer (HFA). Following post-hoc exclusions, based on HFA interpretation indices, 65 participants were retained. Both eyes were combined for analyses (n = 130 eyes). Unsupervised hierarchical clustering of HFA plot data was used to identify patterns of VF loss. A series of mixed effects models (MEM) were performed to test the associations for current Hg exposure with respect to HFA interpretation indices and clusters, as well as for longitudinal past Hg exposure.ResultsThe clustering approach decomposed the light sensitivity deficits into 5 concentric clusters, with greatest loss in the peripheral clusters. No relation was observed between any of the cluster scores and current blood-Hg. VF deficits increased with past Hg exposure. Longitudinal MEM showed that HHg was significantly (p < 0.05) associated with all peripheral, paracentral, and central cluster scores, as well as with HFA interpretation indices.ConclusionsPast Hg exposure in Grassy Narrows First Nation was associated with present day VF loss. The cluster-based location-specific approach identified patterns of VF loss associated with long-term Hg exposure, in both the peripheral and the central areas. The functional implications of this type of visual loss should be investigated.

Implementation study of the CARRA Uveitis Consensus Treatment Plans: feasibility for clinical practice and applicability for research

BackgroundChronic anterior uveitis (CAU) carries a significant risk for eye complications and vision loss. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) introduced consensus treatment plans (CTPs) to standardize treatment for CAU and facilitate future comparative effectiveness studies. Two CTPs were developed to address: 1) initiation of methotrexate (MTX) in patients with CAU naïve to steroid-sparing therapy, and 2) initiation of a TNF inhibitor (TNFi) in patients with severe uveitis or uveitis refractory to MTX. We evaluated implementation of the uveitis CTPs using existing CARRA Registry infrastructure and assessed feasibility of the CTPs for comparative effectiveness research.MethodsThis prospective observational cohort study was conducted at nine pilot sites between February 2020 and August 2022. Patients with JIA-associated CAU (JIA-U) were treated according to either the MTX or TNFi CTP. Uveitis activity and medication use were recorded at 0, 3, and 6 months. We assessed patient enrollment rates, CTP arm selection, uveitis control, and quality of data collection. We also evaluated CTP arm selection in a retrospective cohort of similar JIA-U patients enrolled in the CARRA Registry during the same study period.ResultsSeventeen patients were included in the pilot cohort. Eight were treated with the MTX CTP (4 oral MTX, 4 subcutaneous MTX), and 9 with the TNFi CTP (9 received standard-dose adalimumab, none selected high-dose adalimumab or infliximab). Uveitis was controlled in 13 of 17 patients by 6 months. Query of the CARRA-wide Registry identified 42 patients with JIA-U who were treated according to the MTX or TNFi CTPs. Among these, 26 were treated with MTX (8 oral, 18 subcutaneous) and 16 with TNFi (12 standard dose adalimumab, 2 high dose adalimumab, and 2 infliximab).ConclusionBoth the MTX and TNFi uveitis CTPs can practically be implemented in clinical settings and are currently being utilized across Registry sites. However, in patients starting TNFi therapy, all pilot study participants and most patients across the CARRA Registry were treated with a standard dose of adalimumab. This consensus on the treatment approach underscores its broad acceptance but also limits the applicability of the uveitis TNFi CTP for comparative effectiveness research.

Audiometric Profiles Across a Clinical Population of Children With Hyperacusis.

Hyperacusis (sound sensitivity) is well documented among adults, but little is known about hyperacusis in children. Here, we assess relationships among the presence of hyperacusis, audiometric profiles, and nonauditory factors in a pediatric clinical population. A retrospective review of clinical records from 329 children, ages 2-17 years, was performed to assess the prevalence of hyperacusis and correlations among hearing status, behavioral or communication concerns, and the presence of hyperacusis. In 329 study participants, 18% reported hyperacusis (58% male and 42% female). No significant sex or age differences were found. Hyperacusis was more likely to occur alongside normal hearing or with unilateral hearing loss relative to bilateral hearing loss. Among children with hyperacusis, there was a high prevalence of audiovestibular problems, mental health concerns, speech and language delays, difficulty in school, and behavioral problems. Tinnitus was also found to be comorbid with hyperacusis, but the comorbidity was less than that reported in adults. This study identified common hearing profiles and critical comorbidities in a large clinical cohort of children with hyperacusis. These results demonstrate the urgent need for standardized multidisciplinary assessment and treatment protocols for pediatric hyperacusis.

Game-based Training of Cognitive Functions: An Exploratory Study Involving Seniors in Switzerland

The aging population is resulting in a worldwide rising prevalence of individuals experiencing cognitive decline, whether it be normal age-related changes or pathological conditions. Game-based training in the form of serious games represents an alternative way to enhance cognitive functions among older people. We developed a set of games to train multiple cognitive functions of seniors, considering that their level of digital literacy can vary greatly. A participatory approach has been applied to the development process, involving a multidisciplinary research team and older people. Interviews, usability tests, and a workshop were run with ten seniors (70+) in Southern Switzerland to explore accessibility, usability, and preferences. This paper presents the development process and the games created. Six different games were designed to stimulate multiple cognitive functionalities (e.g., cognitive flexibility, attentiveness, and memory). The serious games run on a tablet. Following Laamarti’s classification, we developed the games to be applied in well-being and health areas, requiring mainly mental activities through visual modalities, played through a touchscreen in a 2D digital environment. Participants appreciated the experience and the challenges provided by the games, understanding the broader aim (cognitive functions training) and the rules, and could complete the required tasks. Feedback was provided on graphical elements (icons and colours), as well as with suggestions for improvements. The tablet appeared to be functional and relatively easy to use, even for first timers. The promising results of this participatory study pave the way for the follow-up phase of the project, which will gather data on the usage of the application and its effectiveness with a greater number of subjects.

European Nurses’ Burnout before and during the COVID-19 Pandemic and Its Impact on Patient Safety: A Scoping Review

Health systems around the world continue to experience healthcare workforce shortages, including shortages of nurses. This results in staff experiencing prolonged shifts and other stressors, which are linked to burnout, yet burned-out staff are then entrusted with the provision of patient care, despite healthcare facilities being regarded as safety-critical areas. It is assumed that the situation may have been worsened by the COVID-19 pandemic. This scoping review aims to identify the prevalence of burnout among nurses in Europe before and during the pandemic, the factors associated with this burnout, and its impact on patient safety. A literature search was conducted in the MEDLINE database; search terms included Nurse and Burnout and Patient Safety and their synonyms. The search limits used were English language, 2013 to 2023 publication years, original published research only (excluding review papers, dissertations, and unpublished reports), and studies conducted in European countries. A total of 16 papers were included for analysis: four indicated burnout levels of study participants, while 11 gave scores for individual burnout symptoms. Almost all studies indicated factors that were linked to burnout or individual dimensions of burnout. A few papers touched on the implications of these factors on patient safety. The review findings concluded that the few studies providing burnout levels on study participants could not give a clear picture of the burnout prevalence among nurses across Europe, either in general, before, or during the pandemic; therefore, this objective was not achieved and more research is required to establish this. Several factors thematically classified as sociodemographic, personal, organizational, and patient/client-related were linked to burnout. However, there were some contradictions in sociodemographic factors. Low personal accomplishment was the most common symptom of burnout before the pandemic, followed by emotional exhaustion and lastly depersonalization. Emotional exhaustion took the lead during the COVID-19 pandemic, followed by low personal accomplishment, and depersonalization remained the least common. More research is needed to establish the relationship between burnout and these factors.

Developing a Supportive Community of Practice

This paper employs a qualitative case study to suggest how the research journey of doctoral students can be improved in educational institutions by encouraging the formation of small and informal Communities of Practice (CoP). It examines themes emerging from the feelings and opinions of four part-time professional doctorate students about their study experience and participation in their emergent CoP. A peer group developed where the students share their experience, expertise, insight, and knowledge in a caring and supportive, but informal, forum. CoP could become an effective tool to aid retention, identity development and wellbeing of postgraduate level students, factors which have been previously identified as key areas of risk. An autoethnographic approach was used to review the feelings, perceptions, and opinions of the four case study group members about their experiences of the informal CoP to date. Thematic analysis of transcripts and WhatsApp communications was used to reveal the perceived common benefits and gains from participation in the informal CoP such as joy, safe spaces, and identity development, aligning members experiences to a CoP lifecycle. The study found small group formation at doctoral programme induction, and encouragement for students to organise their own regular study days using of social channels, may impact overall success. Application and adaptation of this doctoral CoP model could form the basis for future research and a model for academic institutions to suggest to new and existing students

Similar, not universal: the cognitive dimensions of conceptual prototypes of basic emotions in English and in Polish.

The current study explores the differences in conceptualisation of the prototypical basic emotion lexicalisations (anger, disgust, fear, joy, sadness, surprise) in English and in Polish. Measures of concreteness, imageability and context availability were collected and analysed across the six semantic categories of basic emotions, across different parts of speech and between the self-determined genders of the study participants. The initial results indicate that within these cognitive dimensions the conceptualisations of basic emotions in English and in Polish are only similar on the more general but not the higher levels of conceptualisation. The folk-psychological division between positive and negative emotions and the grammatical parts of speech reveal similar patterns in basic emotion concepts in both Polish and in English. However, on the higher levels of conceptualisations that include specific basic emotion semantic categories and self-identified gender, marked language-specific differences become apparent. Different negative emotions drive the statistical differences in Polish and in English, and the gender effects on the measures of concreteness, imageability and context availability are opposite from one language to the other. In other words, basic emotions may be broadly mutually intelligible, but not exactly the same when communicated across languages and cultures.

Bots and fake participants: ensuring valid and reliable data collection using online participant recruitment methods

ABSTRACT Recruitment for successful health sciences research requires balancing efficiency, cost, accessibility, and reliability of available recruitment methods. Our case-control study used online recruitment methods, which broadened our reach to potential participants across the United States. However, this approach also exposed us to challenges associated with bot interference and fraudulent participation. This paper focuses on maintaining data integrity, specifically when utilizing online participant recruitment methods. Drawing from our experience, we propose The Swiss Cheese Model of Study Participant Fraud Prevention, adapted from Reason’s Swiss Cheese Model, and illustrate 10 prevention and verification measures that can be taken to minimize fraud in research studies that rely on online recruitment. We emphasize the importance of a layered approach, including carefully designed recruitment media and compensation protocols, vetting of participant eligibility, and data verification protocols to ensure the validity and reliability of research findings in the digital age.

Comparative study of microneedling monotherapy versus microneedling with autologous platelet-rich plasma for the treatment of stretch marks (striae distensae) and post-surgical scars: Clinical and dermoscopy outcomes

Objectives: Stretch marks and post-surgical scar marks may have negative cosmetic and psychological impacts.. Thus, this study aimed to compare the efficacy and safety of microneedling monotherapy versus microneedling in combination with autologous platelet-rich plasma (PRP) for the treatment of stretch marks and post-surgical scars. Material and Methods: This was a prospective randomized non-controlled study. A total of 30 study participants with stretch marks and post-surgery scars were enrolled and randomly divided into two groups, each with 15 study participants. All received three treatment sessions using microneedling monotherapy (Group A) or autologous PRP with microneedling (Group B) at 4-week intervals. Clinical response to treatment was assessed at the end of 20 weeks by comparing clinical photographs, Manchester Scar scale (MSS) score, dermoscopy images, and patient satisfaction scores. Results: At the end of the study, statistically significant esthetic improvement in terms of MSS scores was seen in Group B when compared to Group A. In Group A, 73.3% of the study participants were satisfied while in Group B, 86.6% were very satisfied with the results. Dermoscopy pictures substantiated the findings of clinical improvement. No major side effects were documented. Conclusion: PRP in combination with microneedling has a better outcome as compared to microneedling monotherapy. Furthermore, dermoscopy is a non-invasive tool that can be used to evaluate therapeutic response.

Understanding Ethical Concerns Involving Vulnerable Human Participant Populations in Medical Research: Mixed-Method Analysis of Liberian Ebola Survivors’ Experiences in PREVAIL I–VII

Background: As the number of large-scale outbreaks continues to rise worldwide, clinical trials are increasingly engaging disease-affected peoples within the Minority World (nations with over 80% poverty rates). Yet global health research inadequately addresses potential ethical issues of including impoverished, disease-affected populations and their contextual vulnerabilities in medical research. Objective: This paper presents a mixed-method analysis from our 2022 semi-structured survey capturing the experiences of Liberian Ebola Virus Disease (EVD) survivors serving as study participants in the Partnership for Research on Ebola Virus in Liberia (PREVAIL) clinical trials. Methods: Firstly, we conducted an extensive literature review of the scholarship related to biomedical research and ethical standards protecting study participants to inform our survey method and design. Applying a theoretical framework on vulnerability, we then qualitatively explored the survey responses of 19 EVD survivors’ perceptions and experiences taking part in PREVAIL, including their expectations, treatment, delivered benefits, and quality of care. We further quantitatively codified their statements for underlying themes of reported negative experiences against standard ethical regulations in biomedical research, conducting a statistical analysis to inform generalizability. Most of the 19 survivors reported facing extreme ongoing vulnerabilities related to their disease status, including physical impairments, psychosocial stress, and socio-economic inequity. Results: Initially, the survivors tended to experience a sense of hope and pride in volunteering for PREVAIL. One in five participants reported benefiting from PREVAIL’s regular medical diagnoses. However, most of their survey responses indicated prevalent negative shared experiences, including continually being confused or misinformed of their study participant rights, roles, and benefits; being burdened by heavy participation transaction costs; and repeated incidents of poor treatment and discrimination by PREVAIL staff after initial recruitment. PREVAIL participant satisfaction ranking is negatively correlated with receiving insufficient financial compensation (r = −0.51), extensive time requirements for each medical visit (−0.40), and being poorly treated by clinical staff (−0.67).

Determinants of low satisfaction with life among wheelchair users with spinal cord injury in Egypt: a cross-sectional study

BackgroundSpinal cord injury (SCI) is one of the most catastrophic injuries that might lead to permanent use of a wheelchair and severely affects the quality of life, hence SCI patients report lower satisfaction with life (SWL) than the general population. Therefore, it is important to identify factors that determine SWL among wheelchair users with SCI. Our study aimed to assess the prevalence of low SWL and to identify its determinants among wheelchair users with SCI in Egypt.MethodsA cross-sectional study included 105 wheelchair users with SCI from the Al Hassan Foundation for wheelchair users in Egypt. The main outcome measure was low SWL, while the independent variables included sociodemographic characteristics, injury-related characteristics, anxiety, depression, neuropathic pain, functional independence, and environmental barriers.ResultsThe prevalence of low SWL among study participants was 57.1%. We found significant associations between SWL and age, area of living, and age at injury. Additionally, SWL correlated negatively with anxiety, depression, neuropathic pain, and environmental barriers, and positively with functional independence. Finally, the binary multiple logistic regression revealed that living in Upper Egypt (p = 0.017, OR = 13.7), depression (p = 0.034, OR = 6.08), older age (p = 0.002, OR = 1.21), and work and school environmental barriers (p = 0.022, OR = 0.46) were the predictors of low SWL.ConclusionTo improve the SWL for wheelchair users with SCI we need to effectively manage neuropathic pain, depression, and anxiety, and promote functional independence. There is an urgent need to reinforce legislation to improve the living conditions for wheelchair users with SCI in Egypt, especially in Upper Egypt.

Coverage and evaluation survey of post-mass drug administration for lymphatic filariasis in four endemic districts of Uttar Pradesh: are we on the track?

There is a persistent high microfilaria rate and variable reporting of coverage of Mass Drug Administration (MDA). The study aims to estimate the coverage, effective coverage, and compliance of drugs administered under MDA and to determine the predictors affecting the effective coverage. A community-based cross-sectional study was conducted in Amethi, Lucknow, Raebareli and Sultanpur districts of Uttar Pradesh, India. The study participants were selected using multi-stage random sampling using Probability Proportional to Estimated Size (PPES). The coverage, effective coverage and compliance of drugs were presented as proportion. The multivariable logistic regression model was applied to identify the significant predictors for effective coverage. Of 4151 participants, 997 (24.0%), 340 (8.2%), 1158 (27.9%) and 1656 (39.9%) belonged to Amethi, Lucknow, Raebareli and Sultanpur districts respectively. The coverage ranged from 49.8% to 87.9% and effective coverage ranged from 51.8% to 73.2% across districts. The compliance was the poorest (70.7%) in Sultanpur. The source of information about MDA, the sex of the study participants and the area of residence emerged as predictors for effective coverage in the districts. The effective coverage was poor with good drug complianceacross the districts. There is a need for a well-designed pre-MDA campaign addressing the fear of side effects of drugs and emphasising the presence of the community during the MDA round along with monitoring and evaluation of the round.

Genomic analysis of Enterobacteriaceae from colorectal cancer patients at a tertiary hospital in Ghana: a case-control study.

Colorectal cancer (CRC) is a severe gastrointestinal cancer and a leading cause of cancer-related deaths in Ghana. The potential role of gut Enterobacteriaceae in the increasing incidence of CRC in Ghana is yet to be thoroughly investigated. In this study, Enterobacteriaceae from CRC patients and healthy control participants were analyzed by whole genome sequencing to identify genomic features that are associated with CRC. Socio-demographic data showed a significant association between age and alcohol consumption and CRC. Escherichia coli was the most abundant Enterobacteriaceae isolated from the study participants and they were predominantly intestinal commensals. Escherichia coli isolates belonging to phylogroup D encoded the highest number of virulence genes. The agn43 and int genes were widespread in Escherichia coli isolates from the CRC patients. Multilocus sequence types of potentially pathogenic Escherichia coli from the CRC patients also encoded genes involved in aggregation, adherence and biofilm formation. The ampC2 and ampH antimicrobial resistance genes were also widespread in the genome of the Escherichia coli isolates. This study highlights the virulence tendencies of Escherichia coli from CRC patients and their ability to transfer virulence determinants to other Enterobacteriaceae residing in the gut.

7789 PCOS and probiotics - a randomized controlled trial with a comparison to metformin

Abstract Disclosure: B.M. Obermayer-Pietsch: None. B. Valentin: None. B. Luegger: None. R. Regina: None. C.W. Haudum: None. V. Tandl: None. Polycystic ovary syndrome (PCOS) has a complex association not only with gonadal hormones, but also with insulin resistance and the gut – showing a decreased alpha diversity of the microbiome in PCOS women. Based on our previous investigations, we conducted a randomized controlled trial (RCT) using probiotics (OMNi-BiOTiC®, Institut Allergosan) and placebo daily, compared to a metformin group over 6 months. In this RCT, we included 112 women with PCOS, defined by Rotterdam criteria. Clinical and biochemical characterisation covered medical history with cycle abnormalities, Ferriman–Gallwey (FG) Score and anthropometric data. Hormonal profiles included gonadal hormones with a focus on androgens and AMH. Oral glucose tolerance tests (oGTT) with parallel insulin/c-peptide determinations and stool sampling for microbiome determination at every visit were done. Study participants were randomized 2:1 for probiotics/placebo or metformin (Glucophage®, Merck) and further 1:1 between probiotics and placebo for 6 months followed by a voluntary 6 months period on probiotics only. NGS for microbiome profiles was carried out. 93 PCOS women completed the study, 19 drop-outs for various reasons including 6 pregnancies were recorded (5 in the probiotic/placebo group, 1 in the metformin group). Participants were 27±5 years old, obesity with a BMI &amp;gt;30 was found in 35% of them. Initial cycle duration ranged from 22 to 200 days, 18% had amenorrhoea. Hirsutism was present with a mean FG score of 12,7±7,71. Mean levels (±standard deviation, reference range, no units depicted) for total testosterone were 0,38±0,15 (0,14-0,77), SHBG 54,1±29,0 (19–117), free testosterone 3,2±3,1 (0,45-2,19) and AMH 8,9±4,8 (0,17-7,37). Initial oGTTs showed insulin resistance prevalent in 43%, with an overall reduction to 36% at visit 2. Weight loss over 6 months was documented in 37%, cycle abnormalities decreased overall to 14%. Group comparisons and microbiome characterisation are ongoing. No serious adverse reactions related to the study medication were recorded. All intervention products were well tolerated in our PCOS study cohort. Based on the intended cycle normalisation, 6 pregnancies were recorded. Metabolic changes were seen both in the probiotic/placebo and in the metformin groups, with fewer changes in the placebo group despite nutritional counselling. Microbiome changes were recorded in both intervention groups. Presentation: 6/3/2024

Development and psychometric assessment of the test “Predictive style”

BACKGROUND: Prognostic processes are an important link in adaptation to stressful events and resilience. The role of the features of prognostic abilities in various mental disorders is shown. We introduce and substantiate a new psychological construct, the “Predictive style”, reflecting the subjective importance of the forecasting process and the tendency to assess the favorability of predicted events. AIM: To develop and conduct a psychometric assessment of the “Predictive style” test. MATERIALS AND METHODS: A “Predictive style” test was developed, including 21 statements divided into 4 scales: excessive optimism, excessive pessimism, excessive forecasting and indifference to forecasts. The development of the test included the study of the external and internal validity, as well as the reliability of the methodology. RESULTS: The measures of compliance with the test model were at a sufficient level: CFI=0.927; TLI=0.917; SRMR=0.0538; RMSEA=0.0497 (95% CI 0.0403–0.0589) and were performed on a new sample. All items correlated with their scales at a sufficient level. The reliability of the scales was in an acceptable range: Kronbach α=0.851–0.630. Retest reliability was confirmed after 2 months. Convergent validity was demonstrated by correlations with levels of optimism, pessimism, anticipation, predictive ability and coping strategies. Statistically significant differences were found between the groups of patients with neurotic mental disorders and those without psychopathology. Multiple linear regression demonstrated that the test scales were statistically significant predictors of anxiety and depression symptoms in the study participants. The results obtained confirm the criteria validity of the test under development. CONCLUSION: The developed test has sufficient psychometric indicators and can be used in subsequent studies.

Enhancing Reading Motivation of Kindergarten Pupils through Home-School Collaboration: A Causal-Comparative Approach

The purpose of this study is to examine how home-school collaboration affects kindergarteners' reading motivation. The researcher chose 100 kindergarten teachers in Talomo A District, Davao City, as study participants. Respondents were chosen using stratified random sampling. A causal-comparative quantitative research design was used. Data was analyzed using these statistical tools: Mean Percentage Scores, Frequency Distribution Percentage, Mean, Independent Sample T-Test, and Eta-Squared Univariate General Linear Model. One category (n=50) was assigned to home-school collaboration and the other to non- collaborative groups by simple random assignment. The results showed that kindergarteners in Talomo A District, Davao City, had extensive reading motivation. Additional results demonstrated a substantial statistical difference in kindergarten students' reading motivation between home- school collaboration and non-collaboration groups. The results also demonstrate that home-school partnership improved kindergarteners in Talomo A District, Davao City. Thus, home-school partnership made this issue easier to teach. The study was done to publish findings in a recognized academic journal.
