From need to action: decoding the role of motivation in adherence to home-based cardiac rehabilitation exercise in chronic heart failure patients

BackgroundAdherence to home-based cardiac rehabilitation exercise remains suboptimal, and motivation may be the intrinsic driving force. This study aimed to explore the role of exercise regulatory motivation in mediating the relationship between psychological needs and exercise adherence among chronic heart failure patients, and to develop a mechanism model.MethodsThis study adopted an explanatory sequential mixed-methods design. A hypothesized model of adherence behavior was developed. A survey was used to test the theory-driven model. A semi-structured interview delved deeper into chronic heart failure patients’ experiences with HBCR exercise, identifying reasons behind significant mediation effects and refining the mechanism model.ResultsA total of 248 eligible chronic heart failure patients participated in the quantitative study. Exercise regulatory motivation partially mediated the relationship between psychological needs and exercise adherence. In the qualitative study, 18 chronic heart failure patients from the quantitative sample were purposefully selected. Five sub-themes emerged from the textual data, which were distilled into two overarching themes: “Specific Functions of Pathway Variables” and “Reasons for Mediation Path Significance.” Integrating the qualitative and quantitative results, it was found that satisfying patients’ psychological needs for exercise activates regulatory motivation, which in turn triggers sustained exercise behavior. As motivation becomes increasingly internalized, patients are able to set clear goals and maintain or adjust their home-based cardiac rehabilitation exercise over the long term.ConclusionFrom a health psychology perspective, this study is the first to reveal the role of exercise regulatory motivation in linking psychological needs and exercise adherence among chronic heart failure patients, ultimately developing a mechanism model.Clinical Trial NumberNot applicable.

Motivating Marketing Research Respondents to Provide More Elaborated Answers

Modern marketing research faces a challenge how to increase the respondents’ productivity and encourage them to give more elaborated answers in the open-ended questions. It’s relevant both for CAWI quantitative projects and the qualitative approaches. The initial research in this area shows that gamified tasks including storytelling enhancements might be a solution to the stated problem. The research project was aimed at the verification of effectiveness of the gamified methods, i.e., questions including a storytelling context, with the use of a bigger, quantitative sample of the regular marketing research respondents – participants of the professional research panel. The research was conducted with the use of the CAWI method on a nationwide sample of 300 people aged 18–40 in an experimental scheme with one control and one experimental group with a gamified task. The participants’ task was to watch TV commercials and fill out a form with an openended evaluation of various aspects of the advertisement. The word count was used as the indicator of the respondents’ engagement. The results of the initial experiments in this field were replicated: application of the storytelling elements to the regular marketing research questions resulted in significantly more elaborated answers in comparison to the traditional approach. However, this effect was valid only for the first impressions check and not for the more detailed evaluation of the commercial. This research project proves that storytelling can be an effective tool to increase the engagement of marketing research participants. It’s a first step in the search for motivating techniques that can be used in different research approaches.

Exploring the Experience of Existential Anxiety During the COVID-19 Isolation Period in a Small Sample of Young Kosovar Adults

International literature has documented the mental health impact of the coronavirus 2019 pandemic on global communities. However, for this period, a significant lack of research exists on the human and psychological experiences of Albanian Kosovars. This study aimed to retrospectively explore a specific experience associated with the isolation period, that is, the Kosovar young adults’ experience of existential anxiety. The notion of isolation is significant for the Kosovars as their country is recently independent with some referencing its political isolation in the European context. The current study was conducted from March to June 2022; Stage 1 included a quantitative sampling of existential anxiety among 115 Albanian Kosovars through the Existential Anxiety Questionnaire (Weems et al., 2004). In Stage 2, five participants with high levels of existential anxiety partook in in-depth interviews. For the qualitative analysis, the Existential Phenomenological Research approach was adopted. Using Paul Tillich’s existential anxiety framework, results revealed that this study’s participants experienced great losses with the start of the lockdown as they were students who had to return to their families. It appears that a process of transformation occurred in light of the hardships that individuals experienced. Implications for mental health practitioners and researchers are offered.

Quantitative sampling by IR-MALDESI is not susceptible to tissue heterogeneity in a multi-organ model.

Quantitative mass spectrometry imaging (qMSI) provides the relative or absolute analyte quantities in a biological specimen in a spatially resolved manner. However, the chemical complexity and physical structure of biological specimens often require one to precisely account for matrix effects in qMSI platforms. Infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI) completely ablates a volume of cryosectioned tissue. This enables the use of a normalization standard that is sprayed underneath the tissue for qMSI applications. Complete sampling has shown to be a significant advantage for qMSI by IR-MALDESI; however, the impact of high tissue heterogeneity has not been systematically studied or quantified. The bias introduced by tissue heterogeneity was investigated by uniformly spraying standards beneath and on top of a whole-body zebrafish section. The quantitative relationship between the signals of the two standards was investigated across this multi-organ model to serve future qMSI experiments by IR-MALDESI and other laser ablation-based sampling methods. The overall ratio between the standards sprayed on top of and beneath the tissue sections remained constant across the entire whole-body section despite significant tissue heterogeneity (e.g., gills, heart, and liver). Additionally, we noted that thinner and/or sucrose-embedded tissues improved these ratios, which will inform future qMSI investigations.

Multifactor Quality and Safety Analysis of Semaglutide Products Sold by Online Sellers Without a Prescription: Market Surveillance, Content Analysis, and Product Purchase Evaluation Study.

Over the past 4 decades, obesity has escalated into a global epidemic, with its worldwide prevalence nearly tripling. Pharmacological treatments have evolved with the recent development of glucagon-like peptide 1 agonists, such as semaglutide. However, off-label use of drugs such as Ozempic for cosmetic weight loss has surged in popularity, raising concerns about potential misuse and the emergence of substandard and falsified products in the unregulated supply chain. This study aims to conduct a multifactor investigation of product quality and patient safety risks associated with the unregulated online sale of semaglutide by examining product availability and vendor characteristics and assessing product quality through test purchases. We used a complex risk and quality assessment methodology combining online market surveillance, search engine results page analysis, website content assessment, domain traffic analytics, conducting targeted product test purchases, visual quality inspection of product packaging, microbiological sterility and endotoxin contamination evaluation, and quantitative sample analysis using liquid chromatography coupled with mass spectrometry. We collected and evaluated 1080 links from search engine results pages and identified 317 (29.35%) links belonging to online pharmacies, of which 183 (57.7%) led to legal pharmacies and 134 (42.3%) directed users to 59 unique illegal online pharmacy websites.Web traffic data for the period between July and September 2023 revealed that the top 30 domains directly or indirectly affiliated with illegal online pharmacies accumulated over 4.7 million visits.Test purchases were completed from6 illegal online pharmacies with the highest number of links offering semaglutide products for sale without prescription at the lowest price range. Three injection vial purchases were delivered; none of the 3 Ozempic prefilled injection pens were received due to nondelivery e-commerce scams.All purchased vials were considered probable substandard and falsified products, as visual inspection indicated noncompliance in more than half (59%-63%) of the evaluated criteria. The semaglutide content of samples substantially exceeded labeled amounts by 28.56%-38.69%, although no peptide-like impurities were identified. The lyophilized peptide samples were devoid of viable microorganisms at the time of testing; however, endotoxin was detected in all samples with levels ranging between 2.1645 EU/mg and 8.9511 EU/mg. Furthermore, the measured semaglutide purity was significantly low, ranging between 7.7% and 14.37% and deviating from the 99% claimed on product labels by manufacturers. Glucagon-like peptide 1 agonist drugs promoted for weight loss, similar to erectile dysfunction medications more than 2 decades ago, are becoming the new blockbuster lifestyle medications for the illegal online pharmacy market. Protecting the pharmaceutical supply chain from substandard and falsified weight loss products and raising awareness regarding online medication safety must be a public health priority for regulators and technology platforms alike.

Molecular identification and phylogenetic analysis of coral and megabenthic species from Gede Island, Central Java, Indonesia

Coral reef ecosystems are home to many organisms, including bivalves, gastropods, crinoids, and demersal fish, making biodiversity assessment crucial for effective conservation and management. This study aims to: i) apply DNA barcoding to identify coral and megabenthic species in coral reef ecosystems, and ii) construct phylogenetic tree to trace their evolutionary relationships. Using quantitative descriptive methods and purposive sampling, specimens were collected in July 2023. The study yielded one coral (R2), one hydrozoan (R3), and one gastropod (GP-1) sample were successfully barcoded. DNA barcoding through Cytochrome Oxydase I (COI) gene amplification revealed that sample R2 had a 98.70% similarity with Acropora hyacinthus, sample R3 had a 98.92% similarity with Zanclea galli, and sample GP-1 had a 91.19% similarity with Erronea errones. Phylogenetic analysis positioned R2 in the same clade as Acropora hyacinthus and related genera such as Montipora, Astreopora, and Alveopora, within the Acroporidae family. R3 clustered with Zanclea galli in the hydrozoan group, alongside Z. sesillis, Z. implexa, and Z. sango. GP-1 grouped with Erronea errones in the gastropod genus Erronea, showing relationships with other genera such as Blasicrura, Cribrarula, Bistolida, and Eclogavena within the subfamily Erroneinae. Species inventories like this are essential for the conservation and management of coral reefs, which are key habitats for fish and other marine life.

Participative development of a culture-sensitive instrument to measure substance use in Syrian refugees

Abstract Background Rarely assessment instruments have been developed with end users such as refugees or those suffering from mental health conditions. Refugees’ experiences pre-, during, and post-flight are associated with various mental health problems including substance use disorders. Systematic reviews on the prevalence of substance use disorders in refugees worldwide show heterogeneous results. To address possible misclassification due to the lack of refugee-sensitive instruments we aimed to develop a refugee-sensitive instrument. Methods We applied a three-step triangulation study design. First, we conducted a three-stage delphi-process in 2019 and 2020. We recruited Syrian medical doctors for the study. Second, we conducted six focus group discussions with Syrian refugees and medical doctors. Third, we conducted expert checks with medical doctors and professionals providing psycho-social services for refugees. For all focus group discussions, audio recordings were translated and transcribed. Computer-assisted thematic analysis was performed applying a deductive approach with semantic coding. Results The refugee-sensitive instrument consists of seven domains of substance use: lifetime use of relevant types of substances, frequency, intensity, self-perception of, and situations posing a risk for substance use, ability to perform, craving, tolerance, and intentions to reduce or quit substance use. Discussion The instrument has been developed qualitatively, however, a limitation is that it could not be validated in a quantitative large sample of refugees. In spite of this limitation, this is - to the best of our knowledge - the first instrument that has been developed in a participatory approach together with end-users. Outlook The study suggests that developing assessment instruments in a participatory approach is feasible. Participatory development of assessment instruments is in line with the new paradigm of co-creation of mental health conditions management.

Joint Leisure Activities of Older Vietnamese Married Couples.

Leisure activities enjoyed by older married couples play an important part in creating more meaningful married lives. The study focuses on the prevalence of joint leisure activities by older couples, the factors influencing older adults' engagement in leisure activities together, and the relationship between joint participation in leisure activities and marital satisfaction of older couples. The quantitative sample included 414 married respondents aged 55 years and above from different parts of Vietnam. The leisure activities analyzed in the paper include vacation/travel, watching movies, music, karaoke singing outside the house, walking around the house, attending cultural events and festivals, watching TV, drinking tea, and doing exercise. The study results showed that the level of joint engagement in leisure activities in places near home with less cost was higher than those engaged in elsewhere. Couples with better living standards, higher education, better health, and who lived in urban areas more actively participated in leisure activities far from home. Vietnamese couples who engage in more leisure activities together had a higher level of overall satisfaction with their marriage, and greater satisfaction in several dimensions of their marital relationship than those who did not participate in leisure activities with their partners.

Hybrid Working and Employee Job Performance in Felcra Berhad: An Examination of The Moderating Role of Job Satisfaction

In today's dynamic work environment, understanding the impact of hybrid working on job performance is crucial. Many organizations, including FELCRA Berhad, adopted hybrid working during the COVID-19 pandemic to enhance employee efficiency and flexibility. This study explores FELCRA Berhad's job performance and satisfaction during the pandemic and evaluates the potential success of hybrid working post-pandemic. Using a quantitative research design and purposive sampling, data were collected from FELCRA Berhad employees through online and physical questionnaires. The data were analyzed with IBM SPSS Version 28 to examine the relationship between hybrid working (working conditions, work-life balance, and recognition) and job performance, with job satisfaction as a moderating factor. The results indicated a significant positive relationship between working conditions and job performance. While work-life balance and recognition showed moderate positive relationships with job performance, they were not statistically significant. Job satisfaction did not significantly moderate these relationships. However, the group effect for hybrid working remained significant across all dimensions. In conclusion, the study confirms a significant positive relationship between hybrid work conditions and job performance, providing a foundation for FELCRA Berhad to consider implementing hybrid work practices based on their direct effects on job performance.

Level of nurse-nurse collaboration and influencing factors in Türkiye and Italy: a mixed-methods study.

Collaboration between nurses is crucial in improving quality in healthcare and plays a key role in increasing nurses' job satisfaction. Our study aimed to investigate the level of collaboration between nurses working in Turkey and Italy and its related factors. The study also deepened the point of view of clinical nurses and nurse managers on this topic. This study was carried out as mixed-methods research including both qualitative and quantitative methods. The study's quantitative sample included 348 clinical nurses. The Nurse-Nurse Collaboration Scale was used to collect quantitative data. Five open-ended questions were used to analyse the nurses' point of view about intraprofessional collaboration. Individual interviews were conducted with 10 clinical nurses and 10 nurse managers. Nurse-nurse collaboration was above the cut off value in both countries. However, significant inter-country differences were found in the collaboration subscales. Qualitative results emphasised that personal characteristics, a specific training in collaboration, the opportunities for comparison and mutual consultation during working shifts may affect the level of collaboration. Nurse managers argued that factors such as manpower planning, suitable working conditions, sufficient materials, empathy, job satisfaction, motivation and effective communication affect collaboration. Greater efforts should be made to implement collaboration between nurses in healthcare settings. Our results help healthcare services in implementing new collaboration policies.

Company Value Moderates The Relationship Of Profitability, Liquidity, And Political Connections To Stock Returns

TInvestors increasingly demand stock investments, as evidenced by the number of Indonesian capital market investors reaching 10 million in 2022. This surge shows the public's high interest in gaining profits from stock investments, necessitating in-depth research on factors influencing stock returns for optimal profits. This research examines the influence of profitability, liquidity, and political connections on stock returns, using firm value as a moderating variable. Employing a quantitative, descriptive methodology and purposive sampling, 29 firms listed in LQ45 from 2020-2022 were selected. The study uses primary and secondary data, analyzed with Eviews 12 software through a panel data regression model. Findings reveal that profitability positively affects stock returns, while liquidity and political connections do not. However, firm value affects stock returns and can moderate the impact of profitability but not liquidity or political connections.

Notes on the spatial distribution of some spider species (Araneae) in a north Norwegian birch forest

In June-August 1968 quantitative samples were taken on the ground in the relatively dark Loc.I and the more open Loc.II, in the moss cover from the upper green third (level A) and from the lower two thirds (level B), at Loc.I also in pure leaf litter. For some spider species spatial segregation (vertically and horizontally) is discussed. The A-layer at Loc.I was dominated by the fairly large Hilaira herniosa (33.1 %) and the medium sized Centromerus arcanus (10.3 %), the small sized Tapinocyba pallens was scarce (3.7 %). In total differences were less clear (17.3 - 22.1 %). T. pallens dominated (43.6 %) in the litter samples, the other two were more scarce. T. pallens was scarce at Loc.II (in total 1.1 %). Here the light coloured Diplocentria rectangulata dominated at the B-level (34.4 %), and the dark pigmented Minyriolus pusillus dominated at the A-level (21.5 %). The former was not found at Loc.I, the latter was scarce (totally absent from the litter samples). A small sweep net material from the two field layers indicates some faunal differences compared to the moss and litter.
