Interactions based in Motivational Interviewing (MI) [1], driven by machine learning, may provide an efficient way to evaluate readiness to quit, elicit behavior change preferences, and scalable flexibility to extend reach to more diversified target populations. This study used patient and public sources of conversational data to develop a Technology Assisted Motivational Interviewing chatbot (TAMI), a digital agent employing machine learning models to deliver MI for tobacco cessation. Consistent with the four tasks of MI (engagement, focusing, evocation, and planning), the creation of TAMI involved 1) utilization of existing de-identified datasets to identify specific smoking topics of interest; 2) incorporation of MI-Consistent utterances to enhance relational connection to TAMI and elicit language expressing interest in quitting (change talk); 3) instilling change talk recognition and topic classification to guide discussion with TAMI and 4) providing tailored treatment options if indicated. Informed by patient, provider, and public discussions about smoking, TAMI can explore motivation associated with tobacco use, and privately employ interventions to elicit change talk, or accurately evaluate readiness for tobacco cessation. TAMI is also scalable technology, which opens the possibility of having more tools for clinical assessment, delivering MI, and tailoring cessation referrals to underserved populations or those with other target behavior goals.

Authors: Velarde Fernanda , Abril-Valdez Elba
Published: October 2024

Objetivo: analizar las actitudes de inclusión hacia las personas trans en instituciones de educación superior en Hermosillo, Sonora. Metodología: enfoque cuantitativo empleando la escala de actitudes hacia las personas trans con muestreo no probabilístico en tres instituciones de educación superior. Resultados: la comunidad universitaria de las instituciones de educación superior públicas reporta en sus respuestas mayor transinclusión en comparación con sus pares de la institución privada. Además, se observa que las personas no binaries, de género diverso y las mujeres son quienes tienen promedios más altos en la escala de actitudes de inclusión hacia las personas trans. Las personas del área de humanidades y las poblaciones estudiantil y LGBTIQ+ presentan actitudes más inclusivas que otros grupos. Limitaciones: debido al muestreo no probabilístico empleado, los datos no son representativos, sino que constituyen una aproximación a la realidad de la región de estudio. Valor: aporte empírico al conocimiento del cisexismo y a la inclusión social de las personas trans. Conclusiones: la transinclusión no se reduce a ser LGBTIQ+, al feminismo decolonial ni a las posturas de izquierda, sino que requiere un conjunto de prácticas que promuevan una legítima inclusión de la población trans.

Authors: Jucá Ana Maria , Lotto Matheus , Cruvinel Agnes , Cruvinel Thiago
Published: October 2024

This scoping review elucidated the characteristics of polarized scientific digital messages credited by researchers for studying the impact of content on people's perceptions. Inclusion criteria encompassed discourse and content analysis studies examining the syntactic and lexical features of polarized messages in online science communication, as well as crossover and randomized information intervention studies. Studies without sufficient detail for data extraction or that did not address message characteristics were excluded. After these exclusions, 10 studies were evaluated for the outcomes. Characteristics of polarized messages were observed to include topic dependency, single viewpoint, discredit of opposing views, emphasis on the minority and flaws of concurrent discourses, and uses of assertive statements, intensifiers, controversy, partisanship, skepticism, sarcasm, vague lexicons, and expert opinion support. As a result, we propose a system of codification for identifying and characterizing polarized discourses in science communication digital messages that can be employed in further content analysis studies.

Authors: Rivera Godoy Jorge Alberto
Published: October 2024

El objetivo de esta investigación es analizar la utilidad contable y residual para conocer el desempeño financiero de la gran empresa panificadora en Colombia en el periodo 2017-2021, siguiendo como metodología el análisis de tendencias de indicadores que miden su eficiencia en el uso de activos, la eficacia en el control de costos y gastos y la efectividad en el logro de utilidades, y cotejándolos con los indicadores de la empresa afín en Europa. Se encuentra que la gran empresa panificadora colombiana logra rendimientos sobre el patrimonio cada año con la misma orientación del margen de utilidad neta, pero menos semejante a su rotación de activos y apalancamiento financiero; resultados semejantes se presentaron en la empresa europea, aunque con valores superiores, salvo el multiplicador financiero. Además, la gran empresa panificadora colombiana creó en promedio un porcentaje de utilidad residual, al igual que su homóloga europea, pero superada por esta última.  La desventaja con respecto a la empresa europea se debe a su menor eficiencia y eficacia, y al uso de recursos financieros a mayor costo. La investigación podría extenderse para grupos homogéneos en edad, fases de su ciclo de vida, estructura legal y comercio internacional.

Published: October 2024

This research aims to compare merit system implementation for top leaders filling positions in North Buton Regency and Kendari City. Another objective is determining the driving and inhibiting factors for implementing the merit system in the two regional government agencies. This study employs the merit principle theory (Stahl, 1979) and the best person theory (McCourt, 2007). The method used is descriptive qualitative; the primary data are obtained from interviews, and secondary data are obtained from documentation and archives. The informant selection technique uses a purposive technique. The research results show that in top leaders filling positions, there are significant differences between the North Buton Regency and Kendari City regarding the merit system principles. The factors influencing the implementation of merit systems in both areas are socio-cultural, political, and organizational. The driving factors to enforce the merit system in Kendari City are greater than its inhibiting factors, while North Buton Regency is the opposite. Nearly all the driving factors in Kendari City are the inhibiting factors in North Buton Regency. However, there is a similarity of non-discriminatory treatment in both local governments. This research contributes to the knowledge and literature pertaining to top leader selection practices in developing countries.

Introduction: Adolescent pregnancy is a major public health concern in low- and middle-income countries. Nepal ranks among the twenty countries with the highest child marriage rates in the world. Adolescent mothers are at higher risk for poorer maternal and neonatal outcomes. This study intended to find the reproductive health issues and use of family planning methods among married adolescent mothers at a tertiary care center in a western part of Nepal. Methods: This was a cross-sectional study conducted among adolescent mothers who attended the family planning counseling session at Community Medicine Out-patient Department at a tertiary care center. Pre-tested semi-structured questionnaire was used for data collection and variables were entered in SPSSTM version 16. Descriptive statistics were presented in terms of mean and percentage. Results: Among 235 adolescent mothers, the mean age of adolescent mothers was 18.02 years (SD = 1.13). Almost 93.2% had not used any kind of contraceptive methods previously. Limited knowledge, uncomfortable talking about contraception and spousal denial were common reasons for not using contraception. Obstetric related complications were observed in 13.6% and one in ten neonates required neonatal intensive care unit admission during the study period. After the counseling session, six out of ten expressed current choice of long-acting reversible contraceptives method in which Jadelle implant was preferred. Conclusion: Our study among the adolescent mothers showed that use of family planning methods before pregnancy had been very low. Policies need to focus on meeting the unmet need for family planning among married adolescent girls.

Published: October 2024

Die Fluchtbewegungen von 2015 haben EU-weit einen neuen öffentlichen Diskurs über die Migration ausgelöst. Dabei geht es um ein breites Spektrum von verschiedenen Standpunkten der einzelnen Länder, die einen breiten Bogen zwischen Akzeptanz und Ablehnung darstellen, was sich u.a. durch den häufigen Gebrauch von sehr unterschiedlichen Schlagwörtern und Argumentationsmustern zeigt. Das Novum dieses Bandes besteht darin, dass ein politisch brisantes Thema einer vergleichenden linguistischen Analyse des sog. Migrationsdiskurses am Beispiel der deutschen, der slowakischen und der ungarischen Pressekommunikation präsentiert wird. Vor dem Hintergrund eines Mehrebenen-Analysemodells wird ein Blick in diskursspezifische Phänomene von der Mikroebene (Wort- und Toposanalyse) bis zur Makroebene (Akteure, Topoi) geboten. Das Werk liefert somit einen wertvollen Beitrag zum sich etablierenden Fachbereich der kontrastiven Diskursanalyse.

Enhancement security and camouflage for free-space optical communication system reliance on switching between structured light beams
Authors: Kadem Kamal H. , Mohammed Mohammed F.
Published: October 2024

This novel study uses structured light beams to enhance security and camouflage in free-space optical (FSO) communication systems. The system employs Bessel, Airy, and Vortex beams due to their properties, such as their unique shapes, adaptability to changing environmental conditions, and spread over long distances while keeping data portable. The structured light beams are dynamically switched during transmission to integrity and security over varying propagation distances and atmospheric conditions. In weak and moderate weather conditions, all three structured light beams can propagate up to 5 km while preserving data integrity. However, under stronger turbulence, the Bessel and Vortex beams can extend beyond 3 km, whereas the Airy beam is limited to a maximum distance of 2 km. The system multi-layered security approach includes beam shaping and selective switching between structured light beams to provide camouflage and enhance data protection, ensuring secure and reliable optical communication even in challenging environments. Simulations using the OptiSystem 18 program demonstrate the system robustness and effectiveness in a high-speed FSO communication.

Authors: Kulesza-Matlak Grażyna , Szindler Marek , Szindler Magdalena M. , Sypien Anna , Major Lukasz , Drabczyk Kazimierz
Published: October 2024

The article presents the results of a SnO2 layer deposition, selected for its properties to function as either a recombination layer or an electron transporting material (ETM) layer in a potential silicon/perovskite tandem solar cell. The layer was deposited using an atomic layer deposition (ALD) method to ensure uniform coverage on the rough surface of etched silicon nanowires. The deposition process was monitored using test samples on glass by assessing surface roughness with an atomic force microscopy method and a total transmission through UV-VIS spectroscopy. The test layers were further characterised to estimate thickness using ellipsometry. The target layers, deposited on the porous surface of etched silicon nanowires, were examined using high-resolution scanning electron microscopy and transmission electron microscopy to evaluate the material microstructure, layer adhesion to the substrate, and the accuracy of ALD deposition on highly porous structures.

Authors: Alekhin M. N. , Grishin A. M. , Skripnikova A. V. , Kapustina A. Yu.
Published: October 2024

An acceleration of blood flow in the diastasis phase with the formation of the so-called L-wave may be found in some patients. The transmitral blood flow is transformed into a triphasic in the presence of L-wave.

Objective: to assess the frequency of L-wave presence and to evaluate the relationship between the presence of L-wave in Doppler imaging of left ventricular blood flow, transmitral blood flow at the level of the mitral valve leaflets, and modern criteria for assessing left ventricular diastolic function.

Material and methods. The study included 105 patients (age 62.21 ± 11.97 (29–91) years, 61 men) with sinus rhythm. From a total of examined patients, 30 were conditionally healthy, 64 patients suffered from coronary heart disease, and 11 suffered from arterial hypertension. Pulsed-wave Doppler ultrasound of transmitral flow was performed in the apical 4-chamber view with the sample volume located at the level of the ends of the mitral valve leaflets, as well as at the level of the basal and middle segments of the left ventricle. The distinct positive wave on the spectrogram during the diastasis phase with a speed exceeding 20 cm/s was considered an additional L-wave, and such blood flow in diastole was considered triphasic.

Results. Triphasic transmitral blood flow was found in 9 patients (8.5%), and triphasic intraventricular blood flow in another 30 patients (28.5%). Patients with triphasic transmitral blood flow were older, with a greater left atrial volume index, and LV diastolic dysfunction was more often detected compared to patients with triphasic intraventricular blood flow (66.7% compared to 23.3%, p = 0.042).

Conclusion. Triphasic transmitral blood flow is revealing significantly less frequently than triphasic intraventricular blood flow (8.5% compared to 28.5%, p < 0.001). Triphasic transmitral blood flow is more often observed in patients with left ventricular diastolic dysfunction.

Purpose. To compare a semi-automatic strain analysis of the left ventricle and left atrium with a manual method in speckle-tracking echocardiography.

Materials and methods. A strain of left ventricle and left atrium was assessed in 110 patients by two methods: manual (Q-Analysis) and semi-automatic (AutoStrain). The following parameters were evaluated: LV global longitudinal strain (LV GLS), LA longitudinal strain during the reservoir phase (LASr), LA longitudinal strain during the conduit phase (LAScd), and LA longitudinal strain during the contraction phase (LASct).

Results. The ROI correction was carried out significantly more often with the semi-automatic method of measuring LV GLS than with manual (40.1% vs. 16.4%, p < 0.05). There were significant differences in LV GLS average values, LASr values, and LAScd values obtained by the semi-automatic and manual methods. LV GLS average values obtained by the semi-automatic method were lower (18.8 ± 2.8% vs. 20.0 ± 3.1%, p < 0.001), and the values of LASr and LAScd obtained by the semi-automatic method were higher (LASr 31.6 ± 9.8% vs. 30.3 ± 10.8%, p = 0.038; LAScd 17.1 ± 7.1% vs. 15.4 ± 6.8%, p < 0.001) than in manual. Semi-automatic method takes more time for LV strain analysis and less time for LA strain analysis than manual method.

Conclusion. The semi-automatic method of LV and LA strain evaluation showed higher reproducibility compared with the manual method. With the semi-automatic method, the values of the LV GLS were lower, and the correction of ROI was required more often and took more time than with manual. The semi-automatic method of LA strain evaluation was characterized by higher values in the reservoir and conduit phases and required less time compared to the manual method. The LA longitudinal strain in the reservoir phase showed the highest values of  reproducibility compared to other LA strain paremeters.

Purpose to evaluate the value of the embryo/fetus heart rate (HR) in early pregnancy assessed by ultrasound for the formation of a group at high risk of adverse pregnancy outcomes.

Materials and methods. A retrospective analysis of ultrasound examinations of 1073 pregnant women at 5+0–10+6 weeks was carried out. The embryo/fetus heart rate was compared with the gestational age calculated by the crown rump length (CRL) and the date of the last menstruation period (LMP). Retrospectively, all examined pregnant women were divided into two groups: group 1—with intrauterine embryo death before 14 weeks of pregnancy (n = 107); group 2—with prolongation of pregnancy until the second trimester (n = 966). When analyzing the data array using a decision tree, the embryo heart rate was assessed at various stages of pregnancy by LMP, CRL, and regardless of the exact period of pregnancy.

Results. Analysis of heart rate values at different stages of pregnancy by LMP showed significant differences in heart rate between groups, the cases of later embryo loss characterized by lover heart rate values. There were no significant differences in heart rate between the groups at different stages of pregnancy by CRL (significant differences were obtained only at 8+0–9+6 weeks). Cut-off values of embryo heart rate for prediction of adverse pregnancy outcomes have been proposed for different stages of pregnancy, as well as a universal cut-off for the entire embryonic period.

Conclusion. The proposed cut-off values of embryo heart rate for different stages of pregnancy, calculated by LMP, may be used for timely prediction of adverse pregnancy outcomes. When the exact gestational age is unknown, a universal heart rate cut-off value of <116 bpm may be used. All proposed HR cut-off values were characterized by high specificity, but none of them by high sensitivity. A sensitivity of HR cut-off values can be increased by the use in combination with other ultrasound and clinical signs of adverse pregnancy outcome.

Computational vector electrocardiography (vECG) is a method for visualizing the total heart vector output in 3-dimensional mode based on 12 lead and distributed computational procedures. This method can be an additional to assess severity and prognosis in patients with acute decompensated heart failure (ADHF).

Objective: to investigate the vECG parameters associated with poor prognosis in patients with ADHF.

Materials and methods. ECG data of 100 patients with ADHF were analyzed. All patients underwent baseline clinical examination, echocardiography, and a natriuretic peptide (NT-proBNP) test. Mortality was recorded during follow-up for 12 months. The correlation of vECG and NT-proBNP parameters with the prognosis of patients was evaluated.

Results. Due to the period of follow-up, 17 patients died. According to vECG data, the surviving patients had a smaller spatial QRS-T angle compared to the deceased patients (p = 0.039). Statistically insignificant values (p = 0.076) of the planarity index in the group of deceased patients were revealed. ROC-analysis revealed the cut-off value of QRS-T spatial angle equal to 164.5°with sensitivity of 53% and specificity of 71%. The QRS-T spatial angle values above the cut-off value indicate a higher probability of lethal outcome. The cut-off value of 999.35 pg/ml of NT-proBNP in patients with the value of QRS-T angle of 164.5° associated with an unfavorable prognosis was revealed.

Conclusions. vECG can be used as a simple method to predict and assess the risk of fatal outcome in patients with ADHF and reduced left ventricular ejection fraction. The most significant parameter is the value of QRS-T spatial angle. An increase in the QRS-T spatial angle is associated with an increased risk of fatal outcome. Thus, vECG analysis may be a useful tool for identification of high-risk patients and influence the treatment strategy.

Objective: to compare 2D ultrasound and 3D with HDlive mode ultrasound in the diagnosis of endometrial polyps in infertility.

Material and methods. The retrospective cohort study included 116 women aged 29 to 43 years (mean age 36.9 ± 3.78) with infertility who were observed at the Nova Clinic Center for Reproduction and Genetics from January 2021 to June 2024. 2D and 3D ultrasounds were performed in all patients. The final conclusion on the presence or absence of pathology was based on the results of the 3D study with HDlive mode. The histological verification of polyps was carried out after hysteroscopy.

Results. Hysteroscopy revealed no signs of pathology in 5 (4.3%) patients; moreover, the results of 2D imaging were also negative, and the results of 3D imaging were positive. In other 111 cases (95.7%), the diagnosis of a polyp was confirmed on hysteroscopy. Among them, no signs of pathology were found on 2D ultrasound in 19 (16.4%) patients. According to the obtained results, the use of 3D imaging with HDlive mode leads to overdiagnosis and false positive results with a chance of 4.5%. On the contrary, 2D imaging leads to underdiagnosis and false negative results with a chance of 19.6%, which is statistically significantly higher than the chance of a false positive result using the 3D method (p = 0.008). Thus, the chance of a false result using the 2D mode is 4.4 [1.57; 12.09] times higher than using the 3D mode.

Conclusions. The study demonstrated a higher accuracy of the 3D ultrasound compared to 2D ultrasound in diagnosing endometrial polyps.
