Shifting Grounds—Facilitating Self-Care in Testing for Sexually Transmitted Infections Through the Use of Self-Test Technology: Qualitative Study (Preprint)
Authors: Trettin Bettina , Skjøth Mette Maria , Munk Nadja Trier , Vestergaard Tine , Nielsen Charlotte
Published: February 2024

BACKGROUND

Chlamydia remains prevalent worldwide and is considered a global public health problem. However, testing rates among young sexually active people remain low. Effective clinical management relies on screening asymptomatic patients. However, attending face-to-face consultations of testing for sexually transmitted infections is associated with stigmatization and anxiety. Self-testing technology (STT) allows patients to test themselves for chlamydia and gonorrhea without the presence of health care professionals. This may result in wider access to testing and increase testing uptake. Therefore, the sexual health clinic at Odense University Hospital has designed and developed a technology that allows patients to get tested at the clinic through self-collected sampling without a face-to-face consultation.

OBJECTIVE

This study aimed to (1) pilot-test STT used in clinical practice and (2) investigate the experiences of patients who have completed a self-test for chlamydia and gonorrhea.

METHODS

The study was conducted as a qualitative study inspired by the methodology of participatory design. Ethnographic methods were applied in the feasibility study and the data analyzed were inspired by the action research spiral in iterative processes using steps, such as plan, act, observe, and reflect. The qualitative evaluation study used semistructured interviews and data were analyzed using a qualitative 3-level analytical model.

RESULTS

The findings from the feasibility study, such as lack of signposting and adequate information, led to the final modifications of the self-test technology and made it possible to implement it in clinical practice. The qualitative evaluation study found that self-testing was seen as more appealing than testing at a face-to-face consultation because it was an easy solution that both saved time and allowed for the freedom to plan the visit independently. Security was experienced when the instructions balanced between being detail-oriented while also being simple and illustrative. The anonymity and discretion contributed to preserving privacy and removed the fear of an awkward conversation or being judged by health care professionals thus leading to the reduction of intrusive feelings.

CONCLUSIONS

Accessible health care services are crucial in preventing and reducing the impact of sexually transmitted infections and STT may have the potential to increase testing uptake as it takes into account some of the barriers that exist. The pilot test and evaluation have resulted in a fully functioning implementation of STT in clinical practice.

Authors: Schoeller Felix , Jain Abhinandan , Dumitrescu Andrei , Johnson Micah , Maes Pattie , Reggente Nicco
Published: February 2024

BACKGROUND

Early maladaptive schemas (EMS) linked to depression are persistent, dysfunctional belief and behavior patterns acquired during critical developmental periods, resistant to change and challenging to address therapeutically. Peak emotional experiences have been shown to mitigate such schemas, suggesting a novel intervention pathway.

OBJECTIVE

This study aimed to evaluate whether AI-generated personalized clones of peak emotional stimuli could selectively deactivate negative schemas, offering a new approach to addressing entrenched cognitive patterns in depression.

METHODS

A total of 182 healthy participants were exposed to three variants of a peak emotional stimulus: the original, a cloned version, and a schema-specific clone targeting negativity. Emotional shifts in valence and arousal were measured pre- and post-exposure to assess the impact on negative schemas. Schema were assessed using the Young Schema Questionnaire (YSQ). Statistical analyses were conducted to compare the effects of the stimuli on schema mitigation.

RESULTS

All stimuli induced robust positive emotional shifts, confirming the method's effectiveness in generating positive affect. However, only the schema-specific stimulus significantly mitigated the targeted negativity schema, outperforming the other stimuli in reducing negative thinking patterns. Qualitative reports underscored the personalized stimulus's relevance and its potential for schema change.

CONCLUSIONS

The findings suggest that AI-generated, schema-specific peak emotional exposures can effectively modify stable maladaptive cognitions, offering a promising new approach to dismantling depressive schemas. This supports the utility of personalized emotional stimuli in mental health interventions, highlighting the potential of AI in enhancing therapeutic outcomes.

Published: February 2024

BACKGROUND

Patient-reported outcomes (PROs) can be defined as any report of a patient’s health taken directly from the patient. Routine collection of PRO data has been shown to offer potential benefits to patient-doctor communication. Electronic forms of PRO measures (PROMs) could be more beneficial in comparison to traditional PROMs in obtaining PROs from patients. However, it is currently unclear whether the routine collection of electronic PRO data could result in better outcomes for patients undergoing laparoscopic cholecystectomy (LC).

OBJECTIVE

This study aims to explore the perspectives of patients and surgeons on the use of electronic PROMs. Based on prior research, technical skill and experience level of the surgeon, long-term quality of life, patient involvement in decision-making, communication skills of the surgeon, cleanliness of the ward environment, and standards of nursing care are identified to be the most important factors for the patients.

METHODS

This is a mixed methods prospective study that will collect both quantitative (survey) and qualitative (interview) data. The study has two components. The first involves the distribution of an electronic presurvey to patients who received elective LC within 48 hours of their surgery (n=80). This survey will explore the perspective of patients regarding the procedure, hospital experience, long-term outcomes, and the perceived value of using PROMs. These patients will then be followed up after 1 year and given another survey. The second component involves the distribution of the same survey and the completion of structured interviews with general surgeons (n=10). The survey will ascertain what PROs from the participants are most useful for the surgeons and the interviews will focus on how the surgeons view routine PRO collection. A convenience sampling approach will be used. Surveys will be distributed through Qualtrics and interviews will be completed on Microsoft Teams.

RESULTS

Data collection began on February 14, 2023. As of February 12, 2024, 71 of 80 recruited patients have been given the presurvey. The follow-up with the patients and the general surgeon components of the study have not begun. The expected completion date of this study is in April 2025.

CONCLUSIONS

Overall, this study will investigate the potential of electronic PRO collection to offer value for patients and general surgeons. This approach will ensure that patient care is investigated in a multifaceted way, offering patient-centric guidance to surgeons in their approach to care.

“Authentic and Amazing”: authenticity as an evaluative category in online consumer restaurant reviews
Authors: Boyle Dominick
Published: February 2024

Claims and evaluations of authenticity are a powerful resource in food discourse: reviewers use evaluations of authenticity to demonstrate their expertise, and restaurants viewed as authentic receive higher star ratings. But the multivalent nature of authenticity presents challenges for researchers. This contribution seeks to understand authenticity by combining computational and corpus driven discourse analysis methods. O’Connor et al. (2017) sought to quantify the impact of authenticity on consumer perception via four theoretical authenticity types (type, craft, moral, and idiosyncratic). This method is tested using a sample of US restaurant reviews and compared to sentiment analysis metrics computed from the same dataset. All types except for moral authenticity showed a positive effect on sentiment. Authenticity in restaurant reviews is further investigated by examining collocates of terms referring to authenticity and compiling keywords of subcorpora created from high and low scoring reviews. Reviewers most often topicalize authenticity in terms of place, taste, and descriptors of ethnicity. These findings illustrate how combining corpus driven discourse analytical and computational methods can illuminate evaluation from multiple perspectives and provide insights which may help to improve computational approaches in the future.

Abstract: Modern society recognizes the significance of Identity and Access Management. It's the method through which information is controlled in terms of who gets access to what and when. Creation of user and system identities is an IAM activity. Data and information sharing relies heavily on safe user access. In addition, most businesses are realizing the growing value of electronic data. Strong authentication is a common solution to this problem and is becoming more and more necessary as the standards for access protection rise. The two most critical IAM concepts that must be handled by the business are identity and access. More and more businesses are turning to an automated system to handle these tasks. But it opens up a new danger. Since these technologies lack the wit to make judgements on their own, we must supplement them with our own brainpower employing a variety of data mining algorithms. This allows us to save data for later model building. Everything you need to know about the difficulties of Identity and Access Management may be found in this document. A potential answer is provided for these problems.
Multilingualism in Academic Publishing and Higher Education in Croatia
Authors: Roncevic Ivana
Published: February 2024

Abstract: The paper deals with the dominant language practices among university teachers and researchers in Croatia with special emphasis on the two dominant languages taught, English and German. The discussed problem relates to the role of English as the lingua franca and the role of German as the second dominant foreign language in the country, as well as the potential presentation of the concept of European multilingualism in the Republic of Croatia. After reflecting on the debate on the role of language choice in academic publishing, i.e., whether the choice of one dominant foreign language is adequate in the search of research insights and truths or whether a richer choice of languages also offers a wider pallette of possible insights, the possibility of 'linguistic imperialism' through the dominance of English is explored. Phillipson's tripartite division of linguicist pro-English arguments is used as the background for the analysis of linguistic practices of Croatian researchers/university teachers. Upon examining the possible linguistic development of different academic disciplines, a dual communicative approach is suggested according to the needs and functions of specific academic domains
Electronic Camming: A Novel Approach to Dynamic Motion Control in Automated Systems
Authors: Malwanker Sahil
Published: February 2024

Abstract: This research investigates the innovative concept of electronic camming, a method for determining the motion of a slave axis (Y) based on the position of a master axis (X) through a pre-defined electronic cam table. In contrast to traditional mechanical camshaft systems, electronic camming utilizes control signals to emulate the motion profile of a physical cam, enabling rapid and effortless modifications without requiring mechanical adjustments. The system's ability to achieve non-linear and uniquely defined slave axis positions for each master axis position simulates traditional mechanical camshaft behavior but in an electronic framework. Leveraging servomotors, actuators, and electronic gearing functions within drives and controllers, electronic camming not only allows dynamic on-the-fly motion profile modifications but also holds the promise of reducing wear and maintenance associated with traditional cam systems. This study contributes valuable insights into the capabilities and potential applications of electronic camming technology, highlighting its significance in the evolution of dynamic motion control within automated systems

Jalisco es uno de los principales estados productores de miel de abejas en México. Sin embargo, la información sobre parasitosis que afectan la productividad de las colonias de abejas melíferas (Apis mellifera) en el estado es limitada y de pocas regiones. El objetivo de este estudio fue determinar la prevalencia e intensidad de dos enfermedades parasitarias de Apis mellifera, varroosis (Varroa destructor) y nosemosis (Vairimorpha spp.), en seis regiones de Jalisco. Se analizaron abejas de 365 colonias colectadas durante la primavera. La varroosis fue la parasitosis más frecuente (90 %) y la nosemosis la menos frecuente (15 %). Los niveles de infestación o infección de las parasitosis fueron en general bajos. Para varroosis, <5 % (ácaros en 100 abejas) y para nosemosis, <310,000 esporas/abeja. Las regiones con mayor prevalencia e intensidad de V. destructor fueron Altos, Centro y Sur, mientras que las infecciones por Vairimorpha ceranae, la única especie del hongo encontrada, fueron significativamente más altas en las regiones Sureste y Sur. Se recomienda realizar estudios epidemiologicos en otras épocas del año para detectar posibles efectos estacionales de las parasitosis para diseñar estrategias para su control.

INTRODUCTION. Malignant neoplasms of the abdominal organs often lead to exacerbation of cardiovascular diseases or trigger their development. Only proper evaluation of cardiovascular risk allows to effectively prepare for the operation, to choose best option of surgery and to decrease the likelihood of complications in the postoperative period.
OBJECTIVE. To study the possibility of a differentiated approach to additional preoperative preparation in the surgical treatment of locally advanced cancer of the abdominal organs in patients with different degrees of cardiovascular risk.
MATERIALS AND METHODS. The first stage included retrospective result analysis of planned surgical treatment of 250 patients under the standard approach to pre-operative examination and preparation. At the second stage, 101 patients were tested a modified algorithm of additional preoperative examination where there was emphasis on persons with an average cardiovascular risk. The observation period did not exceed 30 days. The stratification of perioperative cardiovascular risk was conducted by RCRI and NSQIP-MICA index calculation. Statistical processing of the results was carried out using “Statistica 12.5” application packages (StatSoft, USA).
RESULTS. The standard approach to preoperative preparation was characterized by relatively high mortality in the early postoperative period (18,4%). Most deaths (54,3% on RCRI scale and 69,5% on NSQIP-MICA scale) were among patients of an average cardiovascular risk. Differentiated algorithm implementation of additional preoperative examination has reduced the incidence of postoperative complications by 2,1-5,9 times, the duration of the patient’s stay in intensive care by 1,4 times and hospital mortality by 2,3 times (up to 7,9%).
DISCUSSION. The proposed algorithm is focused on the most problematic subgroup of patients with an average cardiovascular risk (1 risk factor on RCRI scale and/or decreased (indefinite) functional status) which, in standard preparation for surgery, have the same chance of an adverse outcome as persons with high comorbidity.
CONCLUSION. The use of validated methods in evaluating perioperative risk, differentiated approach to additional examination and rational pharmacotherapy reduce hospital mortality in patients with locally advanced cancer of the abdominal organs.

¿Y si Marco Aurelio fuera estoico?
Authors: Hernández García Norma Hortensia
Published: February 2024

El propósito del presente artículo es destacar las peculiaridades de la filosofía de Marco Aurelio respecto al estoicismo clásico, respondiendo a tres inquietudes que presenta el público en su recepción. El primero es el de la afirmación individual, que parece reposar sobre un egoísmo que aleja a las personas de su colectividad; el segundo, la cuestión del conformismo de cara a la idea de providencia que sostiene el estoicismo, y finalmente la compasión como actitud deseable o no. De igual modo, se expone al estoicismo como un fenómeno cultural que ha acompañado a la vida de Occidente y que renace revelando nuestra propia preocupación por la transformación de sí y el amor a los otros.

Published: February 2024

El libro busca contribuir con sustento académico y científico desde las neurociencias y la espiritualidad como ciencia que las experiencias cercanas a la muerte (ECM) aportan al desarrollo integral de la humanidad el conocimiento universal de que la consciencia como tal siempre existe separada del cuerpo físico, de modo que son encuentros espirituales en los diferentes mundos existentes en el universo infinito. Es decir, cuando la persona está en estado de coma o diagnosticada con muerte clínica, está en una condición propicia para vivir experiencias cercanas a la muerte. Por consiguiente, en ese estado el alma (Espíritu encarnado) de la persona sale del cuerpo físico desde la glándula pineal del cerebro por el denominado cordón de plata, que es un vórtice de energía cuántica mediante el cual puede moverse entre los planos físico y espiritual. Todos los casos de ECM que suceden son vivencias espirituales vividas para que la humanidad de este planeta Tierra evalúe su conciencia y su voluntad y haga siempre el bien para evolucionar en los aspectos más importantes de la vida, los cuales son moral y espiritual.

It is well-known that nanofluids differ significantly from traditional heat transfer fluids in terms of their thermal and transfer characteristics. Two of CO2 transfer characteristics, its thermal conductivity and its viscosity, are crucial to improved oil retrieval methods and industries refrigeration. By combining molecular modelling with various machine learning algorithms, this study predicts the conduction characteristics of iron oxide CO2 nanofluids. It is possible to evaluate the accuracy of these transfer parameter estimates by applying machine learning methods such as decision tree, K-nearest neighbors, and linear regression. Predicting these transfer qualities requires knowing the size, fraction of nanoparticle volume, and temperature. To determine the characteristics, molecular dynamics simulations are run using the large-scale atom Vastly equivalent simulant. An inter- and intra-variable Pearson correlation was established to confirm that the input variables were reliant on m and thermal conductivity. The results were finally confirmed by using statistical coefficients of determination. For a variety of temperature ranges, volume fractions, and nanoparticle sizes, the study found that the decision tree model was the best at predicting the transport parameters of nanofluids. It has a 99% success rate.

Published: February 2024

In this study, we conducted temperature, pressure, and stress deformation calculations for the tubing of a specific heavy oil thermal recovery well. Subsequently, we used the axial force on the tubing at the depth of the thermal fluid generator as a boundary condition and incorporated it into numerical simulation software to analyze the thermo-fluid-solid coupled mechanical characteristics of the generator under these operating conditions. Our findings indicate that the cooling water within the generator effectively isolates radial heat transfer from the thermal fluid. Moreover, under steam injection conditions, the maximum von-Mises stress in the generator is concentrated at the head-shell weld.

Authors: Lee Junho , Ahn Myung-Ju , Park Sehhoon
Published: February 2024

Central nervous system (CNS) metastases, including brain and leptomeningeal metastasis, are associated with poor prognosis in epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) patients. CNS metastasis occurs in more than 50% of EGFR-mutated NSCLC cases during the treatment course. The treatment options for CNS metastases in these patients are limited, and there have been ongoing efforts to develop targeted agents with enhanced CNS penetration. AZD3759 (zorifertinib) is a novel EGFR tyrosine kinase inhibitor with a high capability of CNS penetration and proven efficacy with tolerable safety profiles. In this report, we describe a case of a patient with EGFR-mutant NSCLC that was initially diagnosed with multiple brain metastasis who demonstrated prolonged response of both intra- and extracranial lesions over 7 years with AZD3759 as first-line treatment.

These mushrooms have also gained popularity in alternative medicine practices due to their chemical composition and antioxidant properties. This study aimed to determine the biologically important antioxidant activities and total phenolic content of four different mushroom species, each with its unique appearance and habitat: Amanita caesarea (Aca), Clitocybe geotropa (Cge), Cordyceps militaris (Cmi) and Lentinula edodes (Led). The antioxidant activities of the mushroom species were determined using the DPPH radical scavenging method, and the percentage inhibition and IC50 values were reported. The analysis of inhibition values at various concentrations revealed that both Cmi and Aca mushrooms demonstrated higher antioxidant activity when compared to Led and Cge mushrooms across all tested concentrations. Moreover, the phenolic content of the methanolic extracts, quantified in gallic acid equivalents (GAE), were determined to be 37.04±0.35, 52.04±0.41, 19.33±0.11, and 21.63±0.15 mg GAE/g for Cmi, Aca, Led, and Cge, respectively. In conclusion, a direct correlation was noted between the overall phenolic content and the antioxidant activity of the various mushroom species.

Acute flaccid paresis (AFP) is a clinical syndrome complex that requires clinicians to have a wide range of knowledge about the possible causes of its development. The development of AFP can be caused by both an infectious process (inflammatory damage to the spinal cord or its roots) as well as non-infectious reasons. In particular, a rare cause of the development of AFP can be spinal cord neoplasms which require prompt detection and accurate early diagnosis. For these purposes, in addition to clinical data, it is necessary to involve a complex of neurophysiological and neuroimaging examination methods. A clinical observation of AFP in an 8-year-old patient caused by an intramedullary tumor, the process of differential diagnosis and treatment are presented.

Purpose of the research was to establish the characteristics of the cardiovascular system in premature newborns with a birth weight below 2500 gram in their early childhood. Methods used: the data of 302 children born in 2014-2020 in the Tomsk Oblast Regional Perinatal Center named after I.D. Yevtushenko and the Maternity Hospital No. 4 (both located in Tomsk, Russia) were analyzed. The control group of 76 was formed from healthy full-term newborns. The comparison group of 226 consisted of premature infants with birth weight below 2500 gram with the three subgroups depending on birth weight: low (LBW), very low (VLBW) and extremely low body weight (ELBW). During the follow-up that lasted for up to 3 years after birth an anamnesis, physical examination and fixation of the results of paraclinical studies (ECG, EchoCG) were carried out. Results: the probability of having a cardiac diagnosis among children with ELBW at birth at the time of discharge from the obstetric institution was 7 times higher compared to children with LBW (OR=7.60; [CI 95% 1.6-35.3]); birth weight below 1500 gram was associated with a 7-fold greater likelihood of PDA persistence compared to children with LBW at birth (OR=7.44; [CI 95% 3.34-16.55]); in the comparison group at the different age periods the low EchoCG parameters of heart size were established, while normal values of the left ventricular ejection fraction were noted. Conclusion: children with ELBW at birth differed in their cardiological profile already in their early childhood.
