The change and mechanism of soil and soil bacterial diversity during the change of herbaceous litter thickness in desert areas is crucial to understand. In the study, the dominant herbaceous litter mixture in Baijitan National Nature Reserve was selected as the research material, and an experiment was established by adjusting the litter depth. The results showed that the measured values of soil physicochemical factors (total nitrogen, total protein, total potassium, available phosphorus, available potassium, pH, and soil water content) increased with the increase of herbaceous litter mixture thickness in 0–5 cm soil layer. Actinobacteria, Proteobacteria, Acidobacteria, Chloroflexi, and Gemmatimonadetes were the dominant bacterial phyla under different thicknesses of herbaceous litter in 0–5 and 5–10 cm soil layers. Balneimonas, Rubrobacter, and Geodermatophilus were the dominant bacterial genera under different thicknesses of herbaceous litter in 0–5 and 5–10 cm soil layers. There was no obvious change in the α-diversity index of bacterial community the same soil layer, but the α-diversity index in the 0–5 cm soil layer was lower compared to the 5–10 cm soil layer. The results of this study revealed that the change of herbaceous litter thickness had no significant effect on soil bacterial community structure in desert areas.

Published: September 2024

AbstractWe discuss a collider probe of a dark sector model in which the dark matter is charged under a new, hidden U(1) gauge group. In particular, we look for the so-called Darkstrahlung process, in which the final states dark matter radiates a new $$Z^\prime $$

Z
′

gauge boson and it manifests as dilepton resonances. This work emphasizes the potential of dilepton final states with missing transverse energy in probing the darkstrahlung process. We recast the ATLAS Run 2 search for dilepton resonances in association with missing energy in addition to the ATLAS and CMS searches for sleptons. We find that the recasted searches put strong constraints on the coupling between the dark matter and the $$Z^\prime $$

Z
′

. Moreover, we evaluate refined search strategies for $$Z^\prime $$

Z
′

production and propose an analysis employing constraints on the lepton invariant mass and higher missing energy cut related to the darkstrahlung process. Simulation outcomes indicate substantial enhancements, particularly by a factor of 6 in regions featuring lower $$Z^\prime $$

Z
′

masses. Finally, we also discuss the case when the $$Z^\prime $$

Z
′

has a long lifetime, resulting in displaced decay of the boson.

Symbols in the Ambigua by Maximus the Confessor
Authors: Kurdybaylo Dmitry 
Published: September 2024

Abstract
The Ambigua to John by Maximus the Confessor contains numerous passages, where difficulties in the Bible and the Church fathers are interpreted using the terms ‘symbol,’ ‘type,’ and ‘image.’ Symbol appears as a clearly defined exegetic instrument and is always distinguished from other terms. However, in different contexts, Maximian symbolism reveals some peculiarities. On the one hand, the traditional Alexandrian understanding of symbol is accepted by Maximus the Confessor. On the other hand, he tries to employ its Areopagitic interpretation, especially that of the treatises On Mystical Theology and On Ecclesiastical Hierarchy. In two chapters of the Ambigua to John, commenting on the Transfiguration of Christ, Maximus the Confessor interweaves Alexandrian and Areopagitic symbolism, which leads to perplexing formulae, such as of the Incarnate Christ as “a type and symbol of Himself.” The analysis of the foregoing traditions makes it possible to propose an interpretation of this and similar locutions.

Quality assessment and audience engagement with a sexuality education video: Evidence from China
Authors: Li Xiaoqin , Kang Jiayi , Liang Jiaqi 
Published: September 2024

Background: The convenience and accessibility of social media has made it a promising channel for sexuality education worldwide. In China, the popularity of social media such as Bilibili among young users and the increase in sexuality education content on such platforms have sparked concerns over video quality and educational content. Few existing studies have focused on such issues. Objectives: This study aimed to evaluate the characteristics and quality of sexuality education videos on Bilibili, a popular video-sharing social media platform among young people in China, and to explore how video characteristics and quality affected audience engagement. Method: We conducted a content analysis of 203 sexuality education videos on Bilibili. Results and Conclusion: Reproductive health and sexual pleasure were frequently addressed topics, and non-professional individuals were the most common sources of information about these. The involvement of well-known social influencers directly affected user engagement. In addition, video quality had a significant positive impact on user response. The quality of the sexuality education videos was generally high, and of strong educational significance. Hence there may be value in seeing sexuality education videos on such media as supplements to school-based education. Practical implications for improving the quality of sexuality education videos on Bilibili and other social media platforms as well as theoretical insights are discussed.
Determinants of Perception, Adaptation Strategy and Measuring Composite Vulnerability of Agricultural Households to Climate Change in the Desert State Rajasthan, India
Authors: Mohapatra Geetilaxmi , Pandey Suchitra 
Published: September 2024

The study aims to assess agricultural households’ vulnerability, perception and adaptation to climate change in the desert state of Rajasthan, India. A data set of 600 households was collected using a purposive random sampling technique from six districts: Ajmer, Barmer, Jodhpur, Jaipur, Dausa and Tonk. While using the binary logit model, factors affecting the perception and adaptation of agricultural households were assessed, and a composite livelihood vulnerability index was constructed to determine the households’ susceptibility to climate change. The findings suggest that the majority of the households are moderately vulnerable. Of the total households surveyed, 89 per cent of the agricultural households perceive climate change. 83.3 per cent of perceived households used adaptation strategies such as mixed cropping, crop rotation and farm ponds. Socioeconomic variables like the educational status of the household head, farming experience, type of agriculture financial support, agricultural training, land size and access to agricultural institutions influence farmers’ adaptation decisions. Further, lack of information, extension services, access to credit, improved seeds and water, insufficient capital, infertile soil and a labour shortage are barriers to adaptive strategies. Hence, the study recommends effective government policies to enhance credit availability, financial support and agricultural mechanisation for agricultural households. JEL Codes: Q54, Q12, Q18

Published: September 2024

Background: Caregiving in the African American community is informed by strong cultural expectations but may be associated with negative experiences and poor mental health outcomes. Objective: The purpose of this convergent mixed-methods study is to understand the relationship between caregiving experiences and mental health and explore stress management strategies in African American family caregivers of adults with chronic or disabling conditions. Methods: African American family caregivers (N = 100) were recruited using community-engaged methods and completed a sociodemographic questionnaire, the Caregiver Reaction Assessment scale, and the Center for Epidemiologic Studies Depression (CES-D-10) Scale. A subsample (n = 24) participated in semi-structured interviews. Data were analyzed using linear regression and content analysis. A matrix was developed to integrate quantitative and qualitative results. Results: Participants were on average 59 years old. Most were women and provided care to a parent. Lack of family support ( B = 1.37, P = .03) and impact of caregiving on caregivers’ finances ( B = 1.74, P = .004), schedule ( B = 2.92, P < .001), and health ( B = 3.26, P < .001) were associated with depressive symptoms and were reported as stressful experiences. Negative interactions with the care recipient and caring for multiple people emerged as other sources of stress. Participants used independent and interpersonal coping strategies, as well as strategies to facilitate their caregiving role to reduce their stress. Values of reciprocity, limited use of community-based resources, and mental health stigma emerged as important cultural considerations. Conclusions: Our findings suggest the need for culturally-sensitive interventions to improve communication and care coordination within African American family caregiving networks and educational programs about mental health and caregiving resources endorsed by trusted community sources.

Published: September 2024

Background: Managing psychiatric emergencies during pregnancy is often challenging, as the safety of both the mother and the unborn fetus needs to be considered. This study aimed to examine the nature of psychiatric emergencies in pregnancy, their management, and clinical outcomes in women presenting to a psychiatry emergency room (ER). Methods: Charts of perinatal women consulting psychiatry ER between January 2016 and June 2021 were reviewed for the nature of the psychiatric emergency, pregnancy details, psychiatric symptoms, sociodemographic information, medical comorbidities, clinical diagnosis, and care plan. Results: Among 286 perinatal women who attended psychiatry ER, 57 (19.9%) patients were pregnant. Over half ( n = 30, 52.6%) women were multiparous and in their second trimester ( n = 29, 50.9%). Bipolar disorder ( n = 22, 38.6%) was the most common diagnosis. Agitation/aggression ( n = 34, 59.6%) was the most common reason for visiting ER, with risk of self-harm ( n = 14, 24.6%) and risk of harm to the fetus ( n = 7, 12.3%) being other reasons. Emergency psychotropic medications were used in 32 (56.1%) women, with the use of haloperidol in combination with promethazine ( n = 12, 37.5%) or lorazepam ( n = 8, 25%) being the most common. Conclusion: One-fifth of women in the perinatal period presenting to the ER were pregnant. Agitation and aggression were the most common reasons. Parenteral medications were commonly used, and more than a fifth required inpatient care, emphasizing the seriousness of risk.

Authors: Mohanty Krutideepa , Gandhi Sailaxmi , Muliyala Krishna Prasad , Thirthalli Jagadisha , Binu V. S.  , Sharma Kuldeep Kumar 
Published: September 2024

Background: A healthy lifestyle is important for recovery, coping with life’s stresses, minimizing the occurrence and impact of health issues, and improving quality of life. Maintaining a healthy lifestyle may help in preventing or delaying the onset of many health problems. Methods: A quantitative research approach with a randomized control trial (RCT) was adopted. 130 outpatients were randomized to experimental and control groups. The data were analyzed by SPSS version 28.8 and R software. Results: Waist circumference (WC) significantly differed between the experimental group and the control group (F = 14.87, P < .001). There was a decreasing trend in weight in the experimental group across the three time points (baseline to the second assessment), as compared to the control group (F = 4.29, P = .01). Quality of health of the subjects as measured by the visual analog scale (VAS) of the Euro Quality Of Life (EQ5D) significantly differed (F = 87.47, P < .001). Post-intervention, the percentage showed marked improvement in the experimental group. Conclusion: The results of this study support that counseling about a healthy lifestyle is effective as long-term strategies to avoid weight gain, engagement in adequate physical activity, taking nutritious food and maintaining healthy sleep can, in the long run, prevent metabolic syndrome. These interventions can be delivered at a low cost, are safer and practically feasible and may have a long-term impact on the quality of life.

Background: Palliative care is seldom integrated in healthcare in fragile, conflict affected and vulnerable settings with significant refugee populations. Aim: This study aimed to evaluate the integration of palliative care into a fragile, conflict affected and vulnerable community in Northern Uganda. Design: Consecutive Rapid Participatory Appraisals were conducted to evaluate the integration of palliative care in Adjumani District. The first established a baseline and the second, 4 years later, evaluated progress. Data collection included documentary review, key informant interviews and direct observation. Setting/participants: A rural district in Uganda with equal numbers of refugees and host populations living side-by-side. 104 key informants were interviewed, and practice observed in 11 health facilities. Results: At baseline, palliative care was not routinely integrated in the health system. Barriers included health system challenges, cultural beliefs, understanding and trust, mental health issues, gaps in palliative care provision, the role of the community and beliefs about illness impacted care with the village health teams being a trusted part of the health system. Following integration activities including training, mentorship and community sensitisation, the repeat rapid appraisal after 4 years showed a significant increase in palliative care delivery. New themes identified included increased provision of palliative care, the impact of training and community engagement and ownership of palliative care. Conclusion: Community engagement and participation, training interventions and referral pathways enabled the integration of palliative care. Rapid Participatory Appraisal provides a useful framework to evaluate activities aimed at integration of palliative care in a community.
Patient and family perspectives on rural palliative care models: A systematic review and meta-synthesis
Authors: Marshall Claire , Virdun Claudia , Phillips Jane L. 
Published: September 2024

Background: Almost half the world’s population lives in rural areas. How best to provide palliative care to rural populations is unclear. Privileging rural patient and family voices about their experiences of receiving care delivered via rural palliative care models is necessary. Aim: To identify the key palliative care elements that rural patients with palliative care needs and their families perceive to be critical to receiving the care and support they need to live well. Design and Data Sources: A systematic review and meta-synthesis registered with Prospero (CRD42020154273). Three databases were searched in June 2024. Raw qualitative data were extracted and analysed using Thomas and Harden’s three-stage thematic synthesis methodology. Findings reported according to the PRISMA statement. Results: Of the 10,834 identified papers, 11 met the inclusion criteria. Meta-synthesis of extracted, raw quotes (n = 209) revealed three major themes: (1) Honouring the patient’s existing relationship with their General Practitioner (GP); (2) strategically timed access to specialist services, clinicians and equipment is critical; and (3) a need to feel safe, prepared and supported. Conclusion: The strategic inclusion of specialists alongside primary care providers is integral to optimising rural palliative care models. General Practioners are central to these models, through being embedded in their communities and as the conduit to specialist palliative care services. Rural palliative care patients and families value responsive care, trajectory signposting, effective communication, 24/7 support and recognise the value of virtual health. Globally, positive public policy and funding is critical to ensuring access to GP-led, specialist-supported, rural palliative care models.
Fostering nurse-patient relationships in palliative care: An integrative review with narrative synthesis
Authors: Bishaw Suzanne , Coyne Elisabeth , Halkett Georgia KB , Bloomer Melissa J 
Published: September 2024

Background: Nurse-patient relationships are an integral component of person-centred palliative care. Greater understanding of how nurse-patient relationships are fostered and perceived by patients and nurses can be used to inform nursing practice. Aim: To systematically identify and synthesise how nurse-patient relationships are fostered in specialist inpatient palliative care settings, and how nurse-patient relationships were perceived by patients and nurses. Design: Integrative review with narrative synthesis. The review protocol was registered with PROSPERO (CRD42022336148, updated April, 2023). Data Sources: Five electronic databases (PubMed, CINAHL Complete, Medline, Web of Science and PsycINFO) were searched for articles published from their inception to December 2023. Studies were included if they (i) examined nurse and/or patient perspectives and experiences of nurse-patient relationships in specialist inpatient palliative care, (ii) were published in English in a (iii) peer-reviewed journal. The Mixed Methods Appraisal Tool was used to evaluate study quality. Data were synthesised using narrative synthesis. Results: Thirty-four papers from 31 studies were included in this review. Studies were mostly qualitative and were of high methodological quality. Four themes were identified: (a) creating connections; (b) fostering meaningful patient engagement; (c) negotiating choices and (d) building trust. Conclusions: Nurses and patients are invested in the nurse-patient relationship, benefitting when it is positive, therapeutic and both parties are valued partners in the care. Key elements of fostering the nurse-patient relationship in palliative care were revealed, however, the dominance of the nurses’ perspectives signifies that the nature and impact of these relationships may not be well understood.
Communication processes in an advance care planning initiative: A socio-ecological perspective for service evaluation
Authors: Haverfield Marie C , Ma Jessica , Walling Anne , Bekelman David B , Brown-Johnson Cati , Lo Natalie , Lorenz Karl A , Giannitrapani Karleen F 
Published: September 2024

Background: Advance care planning initiatives are becoming more widespread, increasing expectations for providers to engage in goals of care conversations. However, less is known about how providers communicate advance care planning within and throughout a health care system. Aim: To explore perspectives of communication processes in the rollout of an advance care planning initiative. Design: Theoretically informed secondary analysis of 31 semi-structured interviews. Setting/Participants: Key partners in a Veterans Health Administration goals of care initiative. Results: Using the constant comparative approach followed by qualitative mapping of themes to the layers of the Socio-Ecological Model, four themes and corresponding Socio-Ecological layers were identified: Goals of Care Communication Training (Policy, Community, and Institutional) requires more resources across sites and better messaging to reduce provider misconceptions and promote an institutional culture invested in advance care planning; Interprofessional Communication (Interpersonal) suggests care team coordination is needed to facilitate continuity in goals of care messaging; Communication in Documentation (Institutional, Interpersonal, and Intrapersonal) highlights the need for capturing the context for goals of care preferences; and Patient/Family Communication (Interpersonal and Intrapersonal) encourages offering materials and informational resources early to facilitate rapport building and readiness to determine goals of care. Conclusions: Findings support the need for initiatives to incorporate an evaluation of how goals of care are discussed beyond the interpersonal exchange between patient and provider and signal opportunities for applying the Socio-Ecological Model to better understand goals of care communication processes, including opportunities to improve initiation and documentation of goals of care.

Published: September 2024

Objective In this observational study, we determined the distribution of mHealth applications (apps) in Germany using data from the FeverApp registry. Methods The registry data were processed to assess general monthly trends in app distribution, and a seasonal autoregressive integrated moving average model was decomposed to investigate time series. A sample comparison was made matching data from cold-called against self-registered distributers of the FeverApp. Results Among 881 pediatric and adolescent medical practices, 27,300 app users were recruited between 2019 and August 2023. The number of monthly recruited users increased steadily. A seasonal trend was observed, showing a higher distribution in winter months. Self-registered pediatric practices did not recruit significantly more app users than cold-called practices, with approximately every 25th family recruited in both groups. Conclusions The trend of more app sign-ups during winter is likely related to the flu season in Germany. Intrinsic and extrinsic motivational factors of the practices seem to have a large impact on the distribution. We observed a positive trend in the app distribution. Seasonal febrile infections and individual distribution methods among practices influence the distribution of the FeverApp in Germany. Family factors may have a greater influence than the motivation of distributing practices.
