Abstract
The dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are some of the most dark matter (DM) dominated objects known. We report on γ-ray observations of Milky Way dSphs based on six years of Fermi Large Area Telescope data processed with the new Pass8 event-level analysis. None of the dSphs are significantly detected in γ rays, and we present upper limits on the DM annihilation cross section from a combined analysis of 15 dSphs. These constraints are among the strongest and most robust to date and lie below the canonical thermal relic cross section for DM of mass ≲100 GeV annihilating via quark and τ-lepton channels.

Abstract
The Large Area Telescope on board the Fermi Gamma-ray Space Telescope has collected the largest ever sample of high-energy cosmic-ray electron and positron events since the beginning of its operation. Potential anisotropies in the arrival directions of cosmic-ray electrons or positrons could be a signature of the presence of nearby sources. We use almost seven years of data with energies above 42 GeV processed with the Pass 8 reconstruction. The present data sample can probe dipole anisotropies down to a level of 10^{-3}. We take into account systematic effects that could mimic true anisotropies at this level. We present a detailed study of the event selection optimization of the cosmic-ray electrons and positrons to be used for anisotropy searches. Since no significant anisotropies have been detected on any angular scale, we present upper limits on the dipole anisotropy. The present constraints are among the strongest to date probing the presence of nearby young and middle-aged sources.

Abstract
We have measured the gamma-ray emission spectrum of the Moon using the data collected by the Large Area Telescope onboard the Fermi satellite during its first seven years of operation, in the energy range from 30 MeV up to a few GeV. We have also studied the time evolution of the flux, finding a correlation with the solar activity. We have developed a full Monte Carlo simulation describing the interactions of cosmic rays with the lunar surface. The results of the present analysis can be explained in the framework of this model, where the production of gamma rays is due to the interactions of cosmic-ray proton and helium nuclei with the surface of the Moon. Finally, we have used our simulation to derive the cosmic-ray proton and helium spectra near Earth from the Moon gamma-ray data.

Abstract
AIM To develop a comprehensive understanding of resilience and its associated factors among informal caregivers of people with heart failure. DESIGN Transnational multicentre convergent mixed methods approach. METHODS This study was conducted in three European countries: Italy, Spain and the Netherlands; during February 2017 and December 2018. In total, 195 caregivers completed the Connor-Davidson Resilience Scale, Caregiver Burden Inventory and Hospital Anxiety and Depression Scale. From a nested sample 50 caregivers participated in semi-structured face-to-face interviews. Data were analysed using qualitative content analysis, multiple regression and joint displays. RESULTS The caregivers' mean age was over 60 years. The quantitative results showed that caregivers experienced anxiety and depression regardless of a good score of resilience and moderate level of burden. Regression analysis showed that the resilience was associated with caregiver depression. From qualitative findings three resilience inhibiting (psychological outlook, physical weariness and affective state) and two promoting factors (community interconnectedness and self-comforting activities) were generated. Mixed analysis confirmed that depression decreased caregivers' resilience. CONCLUSIONS Caregivers of people with heart failure experience continuous stress and anxiety resulting in reduced resilience. Collaborative efforts are needed to build multifaceted interventions and programs to enhance caregivers' resilience by targeting the factors identified in this study. IMPACT The quality of informal caregiving is affected by the resilience of caregivers. No research has explored the resilience levels and its factors in this population. Depression, psychological outlook, physical weariness and affective state are negative factors of caregivers' resilience. Personal strategies combined with social and community support and belongingness enhance caregivers' resilience. Community care organizations and hospitals could establish alliances to develop programs for enhancing caregivers' resilience.

Abstract
Qualitative research is fundamental to understanding the nature and complexity of human phenomena. While cultural and psychometric validations exist for quantitative tools, the same cannot be said of qualitative ones. There are other many challenges when conducting a multinational qualitative study, which includes different cultural and linguistic 'biases'. This paper presents some key issues that researchers may encounter when designing and developing multinational and multicultural qualitative studies, and also provides some strategies to overcome difficulties and ensure rigour.

Abstract
AIMS To develop a comprehensive understanding of caregiver burden and its predictors from a dyadic perspective. METHOD A convergent mixed methods design was used. This study was conducted in three European countries, Italy, Spain, and the Netherlands. A sample of 229 HF patients and caregivers was enrolled between February 2017 and December 2018 from the internal medicine ward, outpatient clinic, and private cardiologist medical office. In total, 184 dyads completed validated scales to measure burden, and 50 caregivers participated in semi-structured interviews to better understand the caregiver experience. The Care Dependency Scale, Montreal Cognitive Assessment, and SF-8 Health Survey were used for data collection. Multiple regression analysis was conducted to identify the predictors and qualitative content analysis was performed on qualitative data. The results were merged using joint displays. RESULTS Caregiver burden was predicted by the patient's worse cognitive impairment, lower physical quality of life, and a higher care dependency perceived by the caregivers. The qualitative and mixed analysis demonstrated that caregiver burden has a physical, emotional, and social nature. CONCLUSIONS Caregiver burden can affect the capability of informal caregivers to support and care for their relatives with heart failure. Developing and evaluating individual and community-based strategies to address caregiver burden and enhance their quality of life are warranted.

Abstract
The gamma-ray sky has been observed with unprecedented accuracy in the last decade by the Fermi -large area telescope (LAT), allowing us to resolve and understand the high-energy Universe. The nature of the remaining unresolved emission [unresolved gamma-ray background (UGRB)] below the LAT source detection threshold can be uncovered by characterizing the amplitude and angular scale of the UGRB fluctuation field. This Letter presents a measurement of the UGRB autocorrelation angular power spectrum based on eight years of Fermi-LAT Pass 8 data products. The analysis is designed to be robust against contamination from resolved sources and noise systematics. The sensitivity to subthreshold sources is greatly enhanced with respect to previous measurements. We find evidence (with ∼3.7σ significance) that the scenario in which two classes of sources contribute to the UGRB signal is favored over a single class. A double power law with exponential cutoff can explain the anisotropy energy spectrum well, with photon indices of the two populations being 2.55±0.23 and 1.86±0.15.

Abstract
AIMS To explore caregivers' needs and problems in three European countries and associate the clusters of caregivers' needs with their sociodemographic characteristics. DESIGN A qualitative focused mixed methods design was used. METHODS In total, 52 caregivers of heart failure (HF) people were interviewed in three European countries between March 2017 and December 2018. Transcripts were analysed using the seven-phase method of the exploratory multidimensional analysis according to Fraire with Reinert lexical classes findings were organized in dendrograms. Mayring's content analysis was also performed. RESULTS Three clusters of caregivers were identified: spouses, adult children and non-family members. Caregivers not only provide HF patients with vital unpaid support for their physical and emotional needs, but they are continually trying to cope with their social isolation and deteriorating health. CONCLUSIONS Informal caregiving emerged as a complex process influenced by various sociodemographic factors. Gender, relationship type and economic status are the important factors to be considered planning to develop approaches to address the needs of caregivers serving people with heart failure. IMPACT A comprehensive understanding of the nature of informal caregiving of individuals with heart failure, the complexity of the real-world sociodemographic and cultural factors is warranted. The use of the EMDA method gave us the possibility of processing large masses of qualitative data through rapid, complex calculations. In detail, AATD allowed us to study in deep the significant fuzziness of what caregivers expressed and to analyse the content of the entire interviews and to produce global knowledge by using multi-dimensional statistical methods to grasp the fundamental sense of the interviews, beyond the simple words. Three clusters were identified in the samples, including spouses, adult children and non-family members. This study demonstrated that some sociodemographic characteristics could lead to everyday needs. Therefore, these demographic characteristics should be considered in developing targeted interventions. The research was conducted in Europe, but the technique shown can be replicated everywhere. The findings not only impact nursing but can be extended to all those stakeholders who concur with a public health educational mission. PATIENT OR PUBLIC CONTRIBUTION Carers were involved in this study after the discharge of their loved ones or at the time of the outpatient visit. They were involved after they had been observed in their dynamics of involvement in caring of the familiars or friends with heart failure.

Abstract
In recent years, the increase in textual data production has meant that researchers require faster text analysis techniques and software to reliably produce knowledge for the scientific-nursing community. Automatic Text Data Analysis opens the frontiers to a new research area combining the depth of analysis typical of qualitative research and the stability of measurements required for quantitative studies. Thanks to the statistical-computational approach, it proposes to study more or less extensive written texts produced in natural language to reveal lexical and linguistic worlds and extract useful and meaningful information for researchers. This article aims to provide an overview of this methodology, which has been rarely used in the nursing community to date.

Abstract
OBJECTIVES This research aims to explore the perceptions of nursing students and directors of bachelor of nursing degree courses regarding reasons for attrition amongst nursing students. METHODS A qualitative descriptive study was conducted using inductive thematic analysis. The study included a purposeful sample of 12 students and 4 directors of bachelor of nursing degree courses. RESULTS As reasons for attrition, the directors highlighted a lack of preparation for nursing studies and students' limited awareness of possibilities for support and learning. The students emphasized insufficient support from academic staff and poor course organization. Economic and family issues and a misunderstanding of the professional role of a nurse were cited as reasons by both directors and students. CONCLUSIONS The findings provide important insight into attrition in the nursing programme. Further research is warranted, particularly in other contexts. Addressing student attrition requires a comprehensive approach that includes the provision of adequate support systems, mentorship, and resources for students.

Introduction
Resilience is a dynamic process of utilising abilities to harness personal, social, and spiritual resources and coping characteristics and developing regulatory flexibility to manage challenges and bounce back from emotional and physical distress. Caregivers of patients with heart failure are prone to increased stress and reduced resilience while assisting their family members in meeting self-care needs, activities of daily living, and complex medical and dietary regimens. To date, limited research exists on resilience and its predictors among caregivers of people with heart failure.
Purpose
To develop a comprehensive understanding of resilience and its predictors among caregivers of patients with heart failure.
Methods
A convergent mixed methods design was used. In total, 50 caregivers completed the Connor-Davidson Resilience Scale (CDRS) (score range: 0–100, with higher scores indicating higher resilience), the Caregiver Burden Inventory (CBI) (higher scores indicate greater caregiver burden; there are no cut-off points for classifying burden), and the Hospital Anxiety and Depression Scale (HADS) (two subscales, range score 0 and 21 per each subscale; higher scores mean worse anxiety and depression) and participated in semi-structured face-to-face interviews. Data were analysed using multiple regression, qualitative content analysis, and joint displays.
Results
The caregivers’ mean age was 62.8 ± 12.83 years. The CDRS mean score was 62.37 ± 24.2, and the mean HADS scores for anxiety and depression were 12.38 ± 2.74 and 8.54 ± 2.49, respectively. The mean CBI score was 16.82 ± 17.12. Regression analysis showed that the resilience score was only predicted by depression (B = -1.491, p = 0.031). Qualitative analysis generated three resilience-inhibiting factors (psychological outlook, physical weariness, and affective state) and two promoting factors (community interconnectedness and self-comforting activities). Mixed analysis confirmed that depression decreased caregivers’ resilience.
Conclusions
Caregivers of people with heart failure are likely to experience extreme stress and anxiety that affect their resilience to provide better care for their family members. This study identified that depression, hopelessness, pessimism, powerlessness, physical fatigue, and fluctuating emotional states affected negatively caregivers’ resilience. However, self-comforting activities and community interconnectedness improved caregivers’ resilience. Community care organizations and hospitals could establish alliances to develop programs for enhancing caregivers’ resilience.

Abstract
BACKGROUND Informal caregivers contribute substantially to the self-care of people with heart failure (HF) by helping with concrete and interpersonal tasks. Time perception and management are essential issues among caregivers. However, investigators have not explored this topic in caregivers of people with HF. OBJECTIVES The aim of this study was to describe the perceptions and challenges of the time management experience among caregivers who support the self-care efforts of their relatives with HF. METHODS Adult informal caregivers of patients with HF, taking care of the patient for at least 3 months and without cognitive limitations, were recruited from Spain, Italy, and the Netherlands. Data were collected using semistructured interviews. Maryring's qualitative content analysis strategy with both a deductive and an inductive approach was used for analysis. RESULTS We enrolled 50 participants (20 Italians, 19 Spanish, and 11 Dutch). Caregivers had a mean (SD) age of 62.8 (12.8) years and were mostly female (84%). They dedicated 31.2 (SD, 21.7) hours per week to providing caring activities for their patients. After extracting 33 codes from their qualitative interview data, we summarized them into 8 categories and identified 4 main themes: (1) time for yourself, (2) house management, (3) time for the patient (dedicated to directing care), and (4) time for own socialization. CONCLUSION Caregivers navigate the complexity of time management by balancing dedicated time for supporting patients with HF and their own personal time.

Community health services in European literature: A systematic review of their features, outcomes, and nursing contribution to care. Int Nurs Rev 2024; 71:716-728. [PMID: 39073363 PMCID: PMC11600541 DOI: 10.1111/inr.13033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Academic Contribution Register] [Received: 12/21/2023] [Accepted: 07/12/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND To meet the population's needs, community care should be customized and continuous, adequately equipped, and monitored. INTRODUCTION Considering their fragmented and heterogeneous nature, a summary of community healthcare services described in European literature is needed. The aim of this study was to summarize their organizational models, outcomes, nursing contribution to care, and nursing-related determinants of outcomes. METHODS A systematic review was performed by searching PubMed, CINAHL, Scopus, and Embase in October 2022 and October 2023 (for updated results). Quantitative studies investigating the effects of community care, including nursing contribution, on patient outcomes were included and summarized. Reporting followed the PRISMA checklist. The review protocol was registered on PROSPERO (CRD42022383856). RESULTS Twenty-three studies describing six types of community care services were included, which are heterogeneous in terms of target population, country, interventions, organizational characteristics, and investigated outcomes. Heterogeneous services' effects were observed for access to emergency services, satisfaction, and compliance with treatment. Services revealed a potential to reduce rehospitalizations of people with long-term conditions, frail or older persons, children, and heart failure patients. Models are mainly multidisciplinary and, although staffing and workload may also have an impact on provided care, this was not enough investigated. DISCUSSION Community health services described in European literature in the last decade are in line with population needs and suggest different suitable models and settings according to different care needs. Community care should be strengthened in health systems, although the influence of staffing, workload, and work environment on nursing care should be investigated by developing new management models. CONCLUSIONS AND IMPLICATIONS FOR HEALTH POLICY Community care models are heterogeneous across Europe, and the optimum organizational structure is not clear yet. Future policies should consider the impact of community care on both health and economic outcomes and enhance nursing contributions to care.
