The acronym CALL TO ECLS has been proposed as a potential tool to support decision-making in critical communication moments when qualifying a patient for the ECPR procedure. The aim of this study is to assess the accuracy of the acronym and validate its content. Validation is crucial to ensure that the acronym is theoretically correct and includes the necessary information that must be conveyed by EMS during the qualification of a patient with out-of-hospital cardiac arrest for ECMO. A survey was conducted using the LimeSurvey platform through the Survey Research System of the Jagiellonian University Medical College over a 6-month period (from December 2022 to May 2023). Usefulness, importance, clarity, and unambiguity were rated on a 4-point Likert scale, from 1 (not useful, not important, unclear, ambiguous) to 4 (useful, important, clear, unambiguous). On the 4-point scale, the Content Validity Index (I-CVI) was calculated as the percentage of subject matter experts who rated the criterion as having a level of importance/clarity/validity/uniqueness of 3 or 4. The Scale-level Content Validity Index (S-CVI) based on the average method was computed as the average of I-CVI scores (S-CVI-AVE) for all considered criteria (protocol). The number of fully completed surveys by experts was 35, and partial completion was obtained in 63 cases. All criteria were deemed significant/useful, with I-CVI coefficients ranging from 0.87 to 0.97. Similarly, the importance of all criteria was confirmed, as all I-CVI coefficients were greater than 0.78 (ranging from 0.83 to 0.97). The average I-CVI score for the ten considered criteria in terms of usefulness/significance and importance exceeded 0.9, indicating high validity of the tool/protocol/acronym. Based on the survey results and analysis of responses provided by experts, a second version was created, incorporating additional explanations. In Criterion 10, an explanation was added—"Signs of life"—during conventional cardiopulmonary resuscitation (ROSC, motor response during CPR). It has been shown that the acronym CALL TO ECLS, according to experts, is accurate and contains the necessary content, and can serve as a system to facilitate communication between the pre-hospital environment and specialized units responsible for qualifying patients for the ECPR.

Objectives: The aim of the study was to compare left ventricle stroke volume in healthy, eutrophic fetuses in the 2nd and 3rd trimesters evaluated using the velocity time integral and aortic annulus area with left ventricular stroke volume measured using Simpson's single‐plane rule and to determine the discrepancy equation. Methods: The study included 354 fetuses. In each fetus, during the same examination, simultaneous assessment of stroke volume was performed by pulsed‐wave Doppler using the product of the velocity time integral and aortic annulus area and by the fetalHQ® software using Simpson's single‐plane rule. The Mann–Whitney U test was used to compare the "product‐derived" stroke volume and stroke volume using fetalHQ® software values in the 2nd and 3rd trimesters separately. The agreement between the two methods were verified using Bland–Altman analysis. A linear regression model was used to obtain the discrepancy equation. Results: In the 2nd trimester, the mean percentage difference between both the techniques showed that the stroke volume values determined using pulsed‐wave Doppler were, on average, 88% higher than the stroke volume values determined using fetalHQ®. The upper limit of agreement between the compared techniques was approximately 146% and the lower limit of agreement was equal to 29.6%. In the 3rd trimester, the results indicated that the stroke volume values determined using pulsed‐wave Doppler were, on average, 76% higher than the stroke volume values determined using fetalHQ®. The upper limit of agreement between the compared techniques was approximately 129% and the lower limit of agreement was 23%. Based on the results of the linear regression models, discrepancy formulas of the stroke volume values were obtained. The equations to calculate the predicted mean and standard deviations were used to compute the reference intervals for the mean, 5th and 95th centiles. Conclusion: The calculation of left ventricular stroke volume using pulsed Doppler has higher result in relation to stroke volume determined using Simpson's rule significantly. The aortic annulus area showed a higher correlation regarding stroke volume than the velocity time integral in both the 2nd and 3rd trimesters. Stroke volume increased with the increase in aortic annulus area, whereas the velocity time integral remained relatively constant. The retrospective analysis of the collected material enabled the determination of the discrepancy equation. [ABSTRACT FROM AUTHOR]

The aim of this study was to examine if church attendance was associated with quality of life (QoL) and feeling of loneliness among older adults in Poland, and if feeling of loneliness mediated the association. Face-to-face interviews were conducted with randomly selected community-dwelling individuals aged 65+ from the general population, hospital patients, and social service users. Church attendance was positively associated with QoL regardless of confounding factors. Older adults attending church frequently felt less lonely and evaluated their health better. Feeling of loneliness mediated the association between church attendance and QoL. Religiousness should be considered as an important determinant of healthy aging. [ABSTRACT FROM AUTHOR]

The present article aims to highlight methodological aspects related to understanding and conceptualising social capital for the purposes of population research as well as describing the key challenges in the harmonisation process of indicators of social capital. The study was conducted in the frame of the Ageing Trajectories of Health: Longitudinal Opportunities and Synergies (ATHLOS) project. After a review of social capital theories developed in social science and a subsequent review of the documentation of 18 international cohorts, decision trees of the harmonisation of social variables were developed. The known-group validity was verified. The results focused on generalised trust, civic engagement and social participation are presented. The summary of the availability of any indicators of these concepts is classified in seven domains (generalised trust, political participation, religious participation, senior-specific participation, participation in sport groups, participation in volunteer/charity group activities, any participation) across surveys. The results of the analysis for known-group validity support the construct validity of the harmonised variables. [ABSTRACT FROM AUTHOR]

The aim of this cross-sectional study is to examine if neglect is associated with self-rated health (SRH) and if neglect mediates the association between selected factors and self-rated health, among older men and women. The analyses were based on face-to-face computer-assisted personal interviews conducted with 1632 randomly selected community-dwelling individuals aged 65 years and more from among the general population of Lesser Poland. The regression models’ analysis revealed that elder neglect was associated with self-rated health, and the mediation analysis demonstrated that neglect mediates the association between frequency of church attendance and SRH, as well as between marital status (being a widower vs being married) and SRH, among men. These observations can be helpful in better understanding of the broad context of elder neglect in order to develop instruments for an efficient improvement of older adults’ health and quality of life. In addition to this, the study underlines the role of social networks and social engagement as factors which might protect against neglect, and thus improve self-rated health of older people.
