Willingness to participate in a personalized health cohort – insights from the swiss health study pilot phase

BackgroundThis paper explores the feasibility of establishing a large-scale population-based cohort and biobank in Switzerland by assessing potential participants’ needs, expectations, and concerns about such an infrastructure providing information on health, lifestyle, and exposure trajectories, the development of disease, and risk factors over time.MethodsWe utilized a scenario-based questionnaire in the Swiss Health Study pilot phase (2020–2021), involving 1349 adults aged 20–69 from the cantons Vaud and Bern. We conducted descriptive statistics supported by R and qualitative content analysis of n = 374 open responses related to attitudes towards research.ResultsWe highlight the benefits and challenges of the scenario-based approach, discuss the sample represented in the pilot phase, and present implications for building a full cohort. We also report on participants’ attitudes towards and previous experience with health research. We analyze references regarding informed consent and feedback, attitudes towards the Swiss Health Study, and recommendations on improving its scope, design, and instruments. Results indicate a high interest (90%) in participating in a national health study, with 85% of a random population sample willing to join a long-term cohort. Only 43% were familiar with biobanks, and 44% preferred general consent. Trust was high for Swiss-based public research but lower for researchers from other countries or private sector. Over 95% expressed willingness to complete online questionnaires, undergo physical examination, and donate biosamples. Almost all participants wanted to know the outcomes of the medical tests (99.5%) and the exposure to environmental stressors (95%) from their study center visit. Preferred tools for monitoring sleep, physical activity, and diet were known smartphone apps with automatic data management.ConclusionOverall, the study reveals a positive attitude towards personalized health research, with a strong willingness to share data and samples. Key insights focus the meaning of informed consent for participation, the relevance of sampling and representativeness, as well as the significance and challenges of personalized feedback, especially regarding environmental health concerns. Findings emphasize participants’ supportive yet reflexive stances, underscoring the importance of aligning research values with individual values in personalized health research. These insights contribute valuable considerations for refining the scope, design, and instruments of future cohort studies.

Usefulness of combined pseudo-continuous arterial spin labelling and spectroscopic analysis in schizophrenic Egyptian population sample

BackgroundSchizophrenia is a prevalent psychiatric disorder that affects 1% of the global population. Schizophrenia frequently begins in late adolescence or early adulthood, causing significant educational, social, and economic costs for people and society. Functional neuroimaging research on schizophrenia physiopathology has been beneficial. Arterial spin labelling (ASL) is one of functional magnetic resonance imaging (fMRI) technologies that assess brain function without radiation. ASL uses magnetic resonance (MR) imaging to quantify tissue-level brain perfusion non-invasively. Arterial spin labelling (ASL) is one of the functional magnetic resonance imaging (fMRI) technologies that assess the brain function without radiation hazards. ASL uses magnetic resonance (MR) imaging to quantify tissue-level brain perfusion non-invasively. Many publications were performed on role of different advanced MRI techniques in schizophrenia, but our study insisted on the added value of combined ASL and MRS over the conventional MRI in schizophrenic Egyptian population sample.Aim of the workThe purpose of this work was to evaluate the added value of combined ASL-perfusion MRI and MRS in schizophrenic patients.MethodsThis prospective case–control study was carried out on two groups: First group was 30 patients who were diagnosed clinically as schizophrenic patients, and second group was 20 healthy volunteers as a control group for comparison in the period from August 2021 till July 2022.ResultsThe majority of newly diagnosed cases had significant higher positive symptoms than chronic cases. According to arterial spin labelling (ASL) data, rCBF was noticed to be reduced in anterior cingulate, frontal lobe, and parietal lobe of both patients’ subgroups but more significant in chronically ill patients. Convergent results of decreased rCBF were also found in the parietal lobe and occipital lobe. Magnetic resonance spectroscopic analysis showed that NAA was decreased in the anterior cingulate cortex, thalami and basal ganglia of the newly diagnosed cases more than chronic cases. The ASL-MRI perfusion accurately detected the hypo-perfusion of different brain regions with sensitivity 100%, specificity 66.67%, positive predictive value 96.43%, negative predictive value 100%, and accuracy 96.67%, while MR spectroscopy showed sensitivity 100%, specificity 33.33%, positive predictive value 93.10%, negative predictive value 100%, and accuracy 93.33% in evaluation of changes of brain metabolites.ConclusionASL is a promising functional MRI technique that can produce together with MRS quantitative information about the metabolites of different brain regions. The ASL-MRI appears as a reliable non-invasive technique to measure cerebral blood flow and identify decreased rCBF without any contrast administration, and it could be repeatable which helps in early diagnosis as well as follow-up of the progression of the disease.

Psychometric evaluation of the german version of the parent-adolescent communication scale.

The quality of dyadic Parent-Child Communication (PCC) between parents and their adolescent children may be important for the adolescent's general development and mental health during adolescence. Since German instruments for measuring PCC are still lacking, this study aimed to validate the German translation of the Parent-Adolescent Communication Scale (PACS), an internationally established self-report questionnaire. To examine the theoretical-based two-factor model of the PACS in a German population sample of 1044 parent-adolescent dyads, confirmatory factor analyses were used. Moreover, the cross-group measurement invariance of the instrument was assessed. Two clinical samples were used to assess discriminative validity. Bland-Altman plots were used to asses parent-adolescent agreement. The two-factor structure of the PACS was supported. Scalar measurement invariance was established for parent age groups and adolescent gender but not for adolescent age groups and parent gender. Convergent and divergent validity were established. Discriminative validity was only established for the adolescent version in the adolescent psychiatry sample. Test-retest reliability was satisfactory, and rater agreement was medium. The German translation of the PACS is a reliable and valid measurement to assess parent-adolescent communication quality per self-report. Research directions include the concordance discrepancy in clinical samples and further investigation of changes in parents' and adolescents' perspectives on communication problems and open communication.

Fasting before contrast-enhanced CT and the incidence of acute adverse reactions: a single-center randomized clinical trial

ObjectivesTo evaluate the effect of eliminating the traditional preparatory fasting policy before contrast-enhanced CT on acute adverse reactions and to identify potential risk factors in a Spanish population sample, since many European patients still experience this unnecessary measure in clinical practice.MethodsOutpatients who underwent non-emergency CT to either 6 h of solid food fasting (control group) or an unrestricted consumption of solids (intervention group). Adverse reactions during contrast media administration and up to 30 min afterward were recorded and their incidence was calculated. Using univariate and multivariate logistic regression analyses, various patient-related and technical factors were evaluated to identify risk factors for nausea and vomiting.ResultsOne thousand one hundred three patients were evaluated, 560 patients in the control group, and 543 patients in the intervention group. Moderate and severe acute adverse reactions were not identified in either group. No statistical difference was found in the overall acute adverse reactions (hypersensitivity and chemotoxicity) incidence between groups (3.21% vs 2.30% p = 0.36). The total incidence of emetic adverse reactions (nausea and vomiting) was significantly lower in the intervention group than in the control group (0.92% vs 2.86% p = 0.02). Multivariate logistic regression analysis revealed that fasting, age, allergies, neurological diseases, and contrast media concentration were independent risk factors for nausea and vomiting.ConclusionUnrestricted food intake did not increase the overall incidence of acute adverse reactions and diminished the incidence of nausea and vomiting.Trial registrationANZCTR, ACTRN12623000071628. Registered 23 January 2023—retrospectively registered, https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=384985&showOriginal=true&isReview=true.Critical relevance statementThis randomized clinical trial carried out in adults undergoing a non-emergent CT scan demonstrates that fasting as a preparation before a contrast-enhanced CT scan should be discontinued and reserved only for certain specific imaging tests.Key PointsDespite low osmolar CT contrast media becoming ubiquitous, preparatory fasting is still widely practiced.The overall incidence of acute adverse reactions was unchanged after abolishing preparative fasting.Traditional preparatory fasting should be discontinued and reserved only for certain specific imaging tests.Graphical

The relationship between parenting styles and self-esteem of medical students with age and gender as moderators

Introduction: Among various factors that determine an individual’s self-esteem, parenting styles play a significant role. This study investigates the link between parenting styles and self-esteem among medical students while exploring the role of age and gender in this context. Methodology: A cross-sectional study was carried out among medical students from December 2020 to March 2021. An online survey was prepared using the Rosenberg Self-Esteem Scale and Parental Authority Questionnaire-Short Version, and students were asked to fill it out. Data were gathered from 255 students by simple random sampling technique, of which 230 forms were filled. SPSS version 26.0 was used to enter and analyze the data. One sample t-test, Pearson Correlation, and Hierarchal regression analysis were applied. AMOS version 26.00 was used for confirmatory factor analysis. Results: Out of 230 participants, 60% of the sample population experienced an authoritative parenting style. Authoritarian and authoritative parenting styles were significantly correlated with self-esteem. Females who experienced authoritative parenting and males who experienced authoritarian and permissive parenting styles had higher self-esteem than their respective counterparts. Conclusion: Authoritative parenting was the most common and the only parenting style with a statistically significant positive correlation with self-esteem. This study further highlights the importance of consistent parental supervision and open communication in determining an individual’s self-esteem.

Comparison of SARS-CoV-2 seroprevalence estimates between commercial lab serum specimens and blood donor specimens, United States, September-December 2021.

This study was the first systematic comparison between two nationwide severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) studies which estimated seroprevalence, or the proportion of the population with antibodies to the virus, using differing convenience sample populations. One study tested blood donor specimens; the other study tested specimens left over from clinical blood tests. The seroprevalence of anti-nucleocapsid and anti-spike antibodies was compared in the same states during the same months with statistical adjustments based on state demographics. Similar anti-nucleocapsid antibody seroprevalence estimates produced by two independent studies using differing convenience samples build confidence in the generalizability of their anti-nucleocapsid findings. Due to high blood donor vaccine rates, blood donor SARS-CoV-2 anti-spike antibody estimates might overestimate general population seroprevalence, an important consideration for interpreting national seroprevalence study results. Furthermore, because laboratory residuals and blood donations are two common sources of specimens for seroprevalence studies, study findings may be informative for other respiratory virus seroepidemiology studies.

Genetic insights into the gut microbiota and risk of psoriasis: a bidirectional mendelian randomization study

BackgroundGrowing evidence indicates a potential association between the gut microbiome and psoriasis. Nevertheless, the precise nature of these associations and whether they constitute causal relationships remain unclear.MethodsA rigorous bidirectional two-sample Mendelian randomization study was undertaken to establish a putative causal link between gut microbiota and psoriasis. We drew upon publicly available datasets containing summary statistics from GWAS to accomplish this. Utilizing various analytical techniques, including inverse variance weighting, MR-Egger, weighted median, weighted model, and MR-PRESSO, we sought to validate the putative causal association between gut microbiota and psoriasis. A reverse Mendelian randomization analysis was conducted to further investigate the relationship.ResultsAfter conducting a forward Mendelian randomization analysis, a causal relationship was established between 19 gut microbiota and psoriasis. Furthermore, the reverse MR study revealed causality between psoriasis and 13 gut microbiota. Notably, no substantial heterogeneity of instrumental variables or horizontal pleiotropy was observed.ConclusionThis research suggests a potential genetic association and causal nexus between gut microorganisms and psoriasis, indicating potential implications for the clinical management and therapy of psoriasis. Additional observational studies with a larger population sample size and animal model experiments are imperative to fully elucidate this association’s underlying mechanisms.

Estimating Australian Population Utilities for Inherited Retinal Disease Using Time Trade-Off.

Inherited retinal disease (IRD) causes progressive loss of visual function, degenerating towards complete blindness. Economic evaluation of gene therapies for rare forms of genetic IRDs have had to rely on health-related quality of life (HR-QoL) estimates from other diseases because there is limited data available for such a rare condition. This study aimed to estimate Australian societal-based utility values for IRD health states that can be used in cost-utility analyses (CUA) using a time trade-off (TTO) protocol adapted from a UK study. The EuroQol Valuation Technology (EQVT) protocol composite TTO (cTTO) framework was followed, which includes worse-than-death (WTD) states and quality control (QC) measures. Preferences were collected from a general population sample of 110 Australian adult participants. Five health state vignettes from the UK study which had been validated with patients and clinicians were presented randomly to participants during videoconferencing (VC) interviews with one of four interviewers. Technical and protocol feasibility were assessed in a pilot of 10 interviews. QC measures were used to monitor interviewers' performance during the study. One participant withdrew consent. The final analysis was conducted on 109 respondents (including 4 non-traders). The average time to complete the interview was 44.2 minutes (SD 8.7). Participants reported mean visual analogue scale (VAS) scores between 63.15 for 'moderate impairment' and 17.98 for 'hand motion' to 'no light perception'. Mean health state utilities (HSU) varied between 0.76 (SD 0.26) in 'moderate impairment', and 0.20 (SD 0.58) in 'hand motion' to 'no light perception'. Of all HSU evaluations, 14% were considered WTD which most commonly occurred in the most severe visually impaired health state. This study provides valuable information on HSUs across a range of IRD health states from the Australian general population perspective. The utilities obtained in this study can be used as inputs into CUA of IRD therapies.

Translation and examination of construct validity of the Danish version of the Tampa Scale for Kinesiophobia.

This study investigates the construct validity of the Danish Tampa Scale for Kinesiophobia (TSK). The English 17-item scale was translated into Danish adhering to WHO's guidelines. The construct validity of the TSK was examined in a random general population sample of 4,884 18- to 72-year olds with pain within the past 4 weeks. Examination of construct validity adhered to the COSMIN checklist. Structural validity was examined by splitting the sample and conducting exploratory factor analysis on one half and confirmatory factor analysis on the other half. Convergent validity was examined through associations with self-report measures and objective physical performance tests. Reference scores for the TSK were calculated. After translation, all respondents felt confident that they understood the meaning of the items. All but one found the questionnaire acceptable. The exploratory factor analysis suggested that a 1-factor 13-item version without 4 reversed items resulted in the most consistent fit across subgroups of gender, age, and severe pain report. Five different models of the TSK were tested in the confirmatory factor analysis. While none were excellent fits, both one- and two-factor models of the TSK-13 and TSK-11 were acceptable. Two-factor models marginally outperformed one-factor models on goodness of fit. There was no association between TSK scores and muscular fitness or self-reported physical activity. Cardiorespiratory fitness, self-perceived physical fitness, and self-efficacy had weak correlations with TSK scores. Scores showed modest associations with self-report measures of anxiety, illness worry, pain interference, and daily limitations. Based on an overall consideration of results, we recommend using the TSK-13 as a one-dimensional construct for both research and clinical purposes pending further examinations of the TSK in clinical samples. TSK scores from the present study can serve as a standard of reference for levels of Kinesiophobia in the general population.

Ação Imunomoduladora da Estimulação Parassimpática promovida pelo Exercício Físico

Introduction: Physical exercise promotes the stimulation of the vagal nerve and different neural networks, contributing to a more effective anti-inflammatory response in order to contribute to cardiovascular, metabolic and immunological benefits. Objective: To associate the role of physical exercise with parasympathetic stimulation and its possible implications in immunomodulation Methods: This is a qualitative, explanatory and descriptive study on the immunomodulatory action of parasympathetic activation through physical exercise through a bibliographic review. The databases used were: PubMed, Scopus, Scielo and Web of Science involving all original articles from January 2015 and June 2024. Results: The main findings are related to differences in physical exercise intensity, which can contribute to the modulation of the innate immune system and the expression of neutrophil and lymphocyte cell populations, which can contribute to a more specific immune response. Aerobic training and strength training had similar responses in reducing BMI and glycated hemoglobin, reducing sympathetic tone, increasing parasympathetic tone, and improving the sympatho/vagal balance for controlling heart rate variability. There was a negative association between vagal neuroimmunomodulation (NIM) and mortality, since the lower the NIM index, the shorter the survival time in the population sample. Conclusion: Aerobic physical exercise and strength training can contribute to the activation of the parasympathetic system and immune system and provide better adjustments in the innate and adaptive immune response dependent on the intensity and volume of training.

A novel approach for health state valuation: Multiple bounded dichotomous choice compared to the traditional standard gamble

Objectiveto assess the feasibility of a new stated preference approach, the multiple bounded dichotomous choice (MBDC), designed to generate value sets for preference-based measurement of health-related quality of life. MethodsMBDC and standard gamble (SG) tasks were completed to derive SF-6Dv2 value sets from a sample of the general population in Quebec, Canada. Participants were randomized between the two approaches: 6 health states were evaluated in SG and 11 health states in MBDC. Several models were used to estimate data in each approach, and the preferred models were chosen by using mean absolute error (MAE), logical consistency of parameters, and significance levels. Results of MBDC were compared with SG in terms of acceptability (self-reported difficulty and quality levels in answering, and completion time), consistency (monotonicity of model coefficients), accuracy (standard errors), dimensions coefficient magnitude, correlation between the value sets estimated, and the range of estimated values. The intra-class correlation coefficient (ICC) was computed to assess value sets' consistency. ResultsOut of 655 individuals who completed MBDC tasks and 828 who completed SG tasks, a total of 585 participants for MBDC and 714 for SG tasks were included for analysis. The preferred models for both approaches were GLS Tobit. No significant difference was observed in self-reported difficulties and qualities in answers among approaches, but MBDC had less excluded participants and was less prone to report difficulties in answering. Additionally, completion time in the MBDC group was significantly lower (99.80 vs 68.12 s). Most standard errors in the MBDC were lower than those in SG, and the number of non-significant parameters was also lower. The range of utility values generated by MBDC tended to be wider (−0.372 to 1) than those generated by the SG (−0.137 to 1) and the number of worse-than-dead states in MBDC (0.91%) was higher than for SG (0.08%). The Pain dimension was identified as the most significant, while the Vitality dimension showed the lowest significant decrement. Both approaches exhibited a tendency to overestimate severe health state values and underestimate better health state values. The correlation and ICC between the two value sets were 0.937 and 0.983, respectively. ConclusionBased on empirical evidence, it can be inferred that the MBDC method is not only feasible but also holds the potential to generate meaningful and well-informed preference data from respondents. This approach can be used to derive a value set for preference-based instrument.

Awareness of radiation risks by medical students & referrers requesting radiological examinations in the North of Scotland: an audit

IntroductionRadiological imaging has played an important role in diagnostic medicine for over a century, though it is known to contribute to dermatological conditions, cataracts, and cancer. The associated risk of harm has led to the introduction of protective regulations around the world. Present-day NHS clinicians are increasingly requesting and relying on diagnostic imaging. Knowledge surrounding the radiation doses of common radiological investigations and the associated risks is imperative, and on a global level has been found to be inadequate. Consequently, there is a need for the formal inclusion of teaching within training programmes.Aims/objectivesThis prospective audit aims to establish the knowledge of radiation doses and risks of common radiological investigations of both medical students and referrers within four NHS Health Boards based in the North of Scotland. It also seeks to establish prior teaching and the preference for further educational interventions.Audit standardReferrers should have adequate knowledge of radiation doses and the risks associated with common radiological investigations.Audit targetThe standard should be achieved by 90% of referrers.MethodsA 19-question online survey was devised to include subjective and objective questions on ionising radiation awareness, education preference, and respondent demographics, based on RCR (Royal College of Radiologists) audit criteria and previous studies. Data collection was conducted between the 22/02/23 to the 22/03/2023 and the questionnaire was distributed to senior medical students and radiological referrers of different grades within NHS Grampian, NHS Highland, NHS Shetland, and NHS Orkney. A descriptive analysis of the data was undertaken using Microsoft Excel Version 16.71.ResultsTwo hundred eight questionnaires were completed. 22.11% (n = 46) of the sample population had received no prior teaching on the topic of ionising radiation. Over half of the respondents (51.92%, n = 108) rated the importance of radiation risks as either important or extremely important, with 69.71% (n = 145) of participants rating their perceived knowledge as limited or average. Most correctly identified that a CT scan (n = 203), PET-CT scan (n = 199) and a chest x-ray (n = 196) exposed patients to ionising radiation. A small proportion of the participants incorrectly thought that an MRI scan (n = 21) and an ultrasound scan (n = 2) involved ionising radiation. The results obtained failed to meet the RCR audit target, which states that 90% of doctors should be aware of common radiological doses. It was observed that only 17.79% (n = 37) of survey respondents scored over 50% in the knowledge assessment, with the median knowledge score of the whole cohort being 2.5 out of 9 (27.78%).Respondents who had prior teaching on the topic performed better those who had no prior teaching, with average scores of 3.19 (35.44%) and 2.04 (22.67%) respectively. Senior clinicians performed better when compared to junior clinicians and medical students.Conclusion & future recommendationsThis audit found that the knowledge of radiation risks within the North of Scotland in the selected sample population was insufficient across all levels of the clinical team. Further, continuous education around the topic and future audit opportunities may help to optimise knowledge and training.

National health examination surveys; a source of critical data.

The aim of this paper is to contribute technical arguments to the debate about the importance of health examination surveys and their continued use during the post-pandemic health financing crisis, and in the context of a technological innovation boom that offers new ways of collecting and analysing individual health data (e.g. artificial intelligence). Technical considerations demonstrate that health examination surveys make an irreplaceable contribution to the local availability of primary health data that can be used in a range of further studies (e.g. normative, burden-of-disease, care cascade, cost and policy impact studies) essential for informing several phases of the health planning cycle (e.g. surveillance, prioritization, resource mobilization and policy development). Examples of the use of health examination survey data in the World Health Organization (WHO) European Region (i.e. Finland, Italy, Malta and the United Kingdom of Great Britain and Northern Ireland) and the WHO Region of the Americas (i.e. Chile, Mexico, Peru and the United States of America) are presented, and reasons why health provider-led data cannot replace health examination survey data are discussed (e.g. underestimation of morbidity and susceptibility to bias). In addition, the importance of having nationally representative random samples of the general population is highlighted and we argue that health examination surveys make a critical contribution to external quality control for a country's health system by increasing the transparency and accountability of health spending. Finally, we consider future technological advances that can improve survey fieldwork and suggest ways of ensuring health examination surveys are sustainable in low-resource settings.

The effects of single and multiple resistance mechanisms on bacterial response to meropenem.

Meropenem is commonly used against Pseudomonas aeruginosa. Traditionally, the time unbound antibiotic concentration exceeds the MIC (fT>MIC) is used to select carbapenem regimens. We aimed to characterize the effects of different baseline resistance mechanisms on bacterial killing and resistance emergence; evaluate whether fT>MIC can predict these effects; and, develop a novel Quantitative and Systems Pharmacology (QSP) model to describe the effects of baseline resistance mechanisms on the time-course of bacterial response. Seven isogenic P.aeruginosa strains with a range of resistance mechanisms and MICs were used in 10-day hollow-fiber infection model studies. Meropenem pharmacokinetic profiles were simulated for various regimens (t1/2,meropenem=1.5h). All viable counts on drug-free, 3×MIC, and 5×MIC meropenem-containing agar across all strains, five regimens, and control (n=90 profiles) were simultaneously subjected to QSP modeling. Whole genome sequencing was completed for total population samples and emergent resistant colonies at 239h. Regimens achieving ≥98%fT>1×MIC suppressed resistance emergence of the mexR knockout strain. Even 100%fT>5× MIC failed to achieve this against the strain with OprD loss and the ampD and mexR double-knockout strain. Baseline resistance mechanisms affected bacterial outcomes, even for strains with the same MIC. Genomic analysis revealed that pre-existing resistant subpopulations drove resistance emergence. During meropenem exposure, mutations in mexR were selected in strains with baseline oprD mutations, and vice versa, confirming these as major mechanisms of resistance emergence. Secondary mutations occurred in lysS or argS, coding for lysyl and arginyl tRNA synthetases, respectively. The QSP model well-characterized all bacterial outcomes of the seven strains simultaneously, which fT>MIC could not.

Preparing for adulthood: Transitioning from education to the labor market for youth with visual impairments

In this discussion, transition refers to the process of moving from education to the labor market. For young visually impaired individuals, this transition can be particularly challenging and often requires additional support in areas such as developing personal resources. One key trait that can facilitate entry and retention in the labor market is self-esteem. Certain attitudes towards work may also influence the transition. A hedonic-autotelic attitude can motivate a person to look for jobs that offer opportunities for advancement and increase their motivation to pursue such positions even in unfavorable external circumstances. A normative attitude is more likely to drive a person to search for any job, even if it is incompatible with their aptitude, qualifications, or does not provide personal satisfaction. The study aimed to assess the level of self-esteem and attitudes towards work among young visually impaired individuals who are approaching the transition from education to the labor market.The tools used in the study were Morris Rosenberg’s SES Self-Esteem Scale (adapted to Polish by Mariola Łaguna, Kinga Lachowicz-Tabaczek and Irena Dzwonkowska), as well as Agnieszka Czerw’s ‘Attitude Towards Work’ Questionnaire. Regarding the level of self-esteem, it was surprising that none of the respondents obtained a score indicating a high level of self-esteem. A predominance of low self-esteem over average self-esteem could be observed. As for the two types of attitude towards work, the results showed a clear predominance of the normative attitude over the hedonic-autotelic attitude. A very weak negative correlation was found between self-esteem and the normative attitude, while a moderate positive correlation was observed between self-esteem and the hedonic-autotelic attitude. Conclusions: The conducted study was a pilot one, so it would be advisable to carry out wider-scale research on a larger population sample, to compare the results of individuals in relation to the chosen educational pathway, and to repeat measurement when they have already entered the labor market after completing their education.

Association of the oral microbiome with cognitive function among older adults: NHANES 2011–2012

BackgroundAn association between the gut microbiome and cognitive function has been demonstrated in prior studies. However, whether the oral microbiome, the second largest microbial habitant in humans, has a role in cognition remains unclear. Design, setting, participantsUsing weighted data from the 2011 to 2012 National Health and Nutrition Examination Survey, we examined the association between oral microbial composition and cognitive function in older adults. The oral microbiome was characterized by 16S ribosomal RNA gene sequencing. Cognitive status was assessed using the Consortium to Establish a Registry for Alzheimer’s Disease immediate recall and delayed recall, Animal Fluency Test, and Digit Symbol Substitution Test (DSST). Subjective memory changes over 12 months were also assessed. Linear and logistic regression models were conducted to quantify the association of α-diversity with different cognitive measurements controlling for potential confounding variables. Differences in β-diversity were analyzed using permutational analysis of variance. ResultsA total of 605 participants aged 60–69 years were included in the analysis. Oral microbial α-diversity was significantly and positively correlated with DSST (β, 2.92; 95% CI, 1.01–4.84). Participants with higher oral microbial α-diversity were more likely to have better cognitive performance status based on DSST (adjusted odds ratio, 2.35; 95% CI, 1.28–4.30) and were less likely to experience subjective memory changes (adjusted odds ratio, 0.43; 95% CI, 0.25–0.74). In addition, β-diversity was statistically significant for the cognitive performance status based on DSST (P = 0.031) and subjective memory changes (P = 0.023). ConclusionsOral microbial composition was associated with executive function and subjective memory changes among older adults among older U.S. adults in a nationally representative population sample. Oral dysbiosis is a potential biomarker or therapeutic target for cognitive decline. Further work is needed to elucidate the mechanisms underpinning the association between the oral microbiome and cognitive function.

Premenstrual syndrome among medical versus non-medical workers and its association with work-related quality of life

BackgroundPremenstrual syndrome (PMS) is a commonly underestimated disorder that negatively impacts a woman’s life. Medical workers, who live a more stressful life, may report an increased rate of PMS. Studies on the relationship between PMS and work-related quality of life for medical professionals are scarce, particularly in the Arab world. This study aimed to compare the frequency of PMS among medical versus non-medical workers at Zagazig University and to assess the association between PMS and their work-related quality of life.MethodsA comparative cross-sectional study was conducted. The sample population consisted of 48 medical and 48 non-medical female workers aged 18–45 years from Zagazig University. The two groups filled out a questionnaire with 3 parts: sociodemographic and occupational data, the Premenstrual Symptoms Screening Tool (PSST), and the Work-Related Quality of Life Scale (WRQL).ResultsSevere PMS was reported in 45.8% of medical workers versus 20.8% of non-medical workers with a statistically significant difference between both groups (p = 0.009). Binary logistic regression showed that being a medical worker, clinical specialty, ≥ 8 years of work, ≥ 24 working hours per week, and having a non-set hourly schedule were predictors for severe PMS. PMS was found to be a statistically significant predictor of poor WRQL (p < 0.001). There was a highly significant negative correlation between the PMS score and the WRQL score (r = − 0.302, p < 0.001).ConclusionAmong medical workers, PMS is more common and more severe, and WRQL is worse and negatively correlated with PMS. We suggest further studies with larger samples to prove this association and planning for public health programs to screen for and manage PMS among medical workers in our community.

Quality of Life Among Breast Cancer Patients in Mures County, Romania: A Cross-Sectional Study.

Background and aim Psychiatric pathology does not always start on its own but may be conditioned or triggered by a comorbidity with a high impact on the human psyche. When there are comorbidities, psychiatric pathology can occur due to the high diagnostic burden. Our study aims to find out if there is a correlation between the diagnosis of breast cancer and its severity,and psychiatric symptoms such as depressive mood, atypical anxiety, or even autolytic ideation that directly influence the quality of life of patients. Materials and methods The study is a prospective, cross-sectional, single-center study carried out between December 2023 and June 2024 at the Mureș County Clinical Hospital in Romania. The sample population had to be at least 18 years old and had to bediagnosed with breast cancer recently.We applied two tests, WHODAS 2 (World Health Organization's Disability Assessment Schedule 2.0) and level 1 (level 1 of cross-sectional measurements of symptoms), to be able to measure and aid assessment of mental health domains that are important across psychiatric diagnoses and also the degree of disability triggered by breast cancer. The statistical analysis included descriptive statistics and interferential statistics. Statistical tests, such as Shapiro-Wilk, Kruskal-Wallis, and Mann-Whitney U tests with Bonferroni correctiontests, were used.The p-value was set to 0.05 with a confidence interval (CI) of 95%. Results The study included 120 women diagnosed with breast cancer, with a mean age of 56.64 ± 9.46 years. Regarding the severity of the diagnosis, 44 women (36.66%) had non-invasive cancer, 58 (48.33%) had invasive cancer, and 18 (15%) had metastases.There was a statistically significant difference between three of the five selected level 1 domains across cancer types.The WHODAS 2.0 disability scores showed a significant difference between groups (p < 0.001). Subjects with non-invasive cancer had the lowest WHODAS 2.0 score, followed by the invasive group, while metastases had the highest score. Conclusions Following the application of the two tests, level 1 and WHODAS 2.0, to our group of subjects, statistically significant differences were observed between the three categories of subjects. The degree of disability and the occurrence of psychological symptoms differed according to the severity of breast cancer. Adapting to the status of an oncological patient entails multiple changes from a psycho-emotional, social, occupational, and professional point of view. Although the most recent medications prolong survival, a holistic approach that considers psychological aspects can improve patients' long-term results.

Lietuviškosios Viešojo kalbėjimo nerimo skalės faktorių struktūra ir patikimumas

Social Anxiety Disorder (SAD) is especially prevalent among young individuals aged 18–25 and significantly affects daily social activities and interpersonal relationships. Public Speaking Anxiety (PSA), a subtype of SAD, is a widespread concern that affects one in five individuals. The study focuses on the Public Speaking Anxiety Scale (PSAS), with the aim of assessing the factor structure and reliability of the Lithuanian version (PSAS-LT). The PSAS-LT, administered to 227 participants aged 18–25, comprises 17 Likert-scaled items, evaluating cognitive, behavioral, and physiological aspects of PSA. Three models were tested: a single-factor model, a three-factor model and a single factor model with positive and negative item wording factors model. Results indicate less than desirable fit for the single, and three-factor models, suggesting the need for alternative structures. The model that included a single factor as well as positive and negative item wording factors demonstrated a reasonably good fit. The diagnostic validity confirmed that the PSAS-LT effectively differentiated between participants with and without history of anxiety disorders. The total score of the PSAS-LT had excellent internal consistency. Despite limitations, including convenience sampling and nonrepresentative sample, the study contributes valuable insights into refining the understanding of PSA assessment features, emphasizing the importance of considering response patterns. Future research should validate these findings with larger and more diverse samples of the Lithuanian population.

Nursing Informatics Competency among Nurses at a Teaching Hospital in Malaysia

Nursing informatics merges nursing science with information and analytical sciences to identify, describe, manage, and disseminate nursing data, information, knowledge, and wisdom. Identifying nurses’ informatics competency will help improve information technology utilisation in clinical practice. The aim of this study was to assess basic competency in nursing informatics and related factors influencing nurses working in a university teaching hospital. Thus, a cross-sectional study was conducted. A stratified random sampling of the total population of 1,136 nurses with sample size of 316 nurses participated in this study. The data was collected using a self-reported questionnaire utilising the Nursing Informatics Competency Assessment Tool (NICAT) reaching targeted sample by convenient approach. The results of this study showed that 85% (n = 269) nurses were competent in nursing informatics competency. There was a significant relationship between basic nursing informatics competency and sociodemographic of age (t = 4.194, p = 0.000), gender (t = –2.558, p = 0.011), educational level (F [2,313] = 5.094, p = 0.007) and working discipline (F [6,309] = 8.309, p = 0.000). There was also a significant relationship between basic nursing informatics competency and working experience (ρ = –0.231, n = 316, p = 0.000). However, the study is based on self-reporting and does not measure the actual performance of nursing informatics competency. Overall, the findings indicated the need for improvement in nursing informatics by exposure or awareness for potential age group and particular clinical setting for training and educational of nursing informatics.
