Titan Mare Explorer (TiME): first in situ exploration of an extraterrestrial sea

The lakes and seas of Titan are a sink of products of photolysis in the atmosphere, and a crucial component in Titan's active methane cycle. In situ exploration of the seas is necessary to understand their intriguing prebiotic organic chemistry

Patient perspectives on breast cancer treatment plan and summary documents in community oncology care

BACKGROUND: Although the routine use of treatment plans and summaries (TPSs) has been recommended to improve the quality of cancer care, limited data exist about their impact on quality, including patient satisfaction and coordination of care. METHODS: Patients received TPSs as part of the American Society of Clinical Oncology Breast Cancer Registry (BCR) pilot program of 20 community oncology practices. Participants were surveyed 2 to 4 weeks after receiving a TPS to evaluate their perceptions of the document. Patients who were receiving chemotherapy received the TPS as separate plan and summary documents (at the start and the end of treatment) and could complete 2 surveys. Others received a single integrated TPS. Eligible survey participants had stage 0 through III breast cancer and were enrolled in the BCR. RESULTS: Of 292 consented patients, 174 (60%) completed at least 1 survey. Of 157 patients who recalled receiving a TPS, 148 (94%) believed that the documents improved patient‐physician communication, and 128 (82%) believed that they improved communication between physicians; 113 (72%) said the documents increased their peace of mind, whereas 2 (1%) had less peace of mind. Of 152 patients (97%) who still had their documents, 147 (97%) said they were useful, and 94 (62%) had given or planned to give the documents to another physician. All 63 patients who were surveyed after receiving a summary recommended that practices continue to provide TPSs to patients. CONCLUSIONS: Participants in this study expressed high satisfaction with TPSs. Additional research is needed to study the broad‐scale implementation of the BCR and to evaluate the impact of routine use of TPSs on the quality of care delivered.

A qualitative study of unmet needs and interactions with primary care among cancer survivors

INTRODUCTION: Despite increasing numbers, there is little research investigating the long-term needs of cancer survivors. The aim of this study is to explore the experiences of individuals who have survived at least 5 years following a cancer diagnosis, and to describe perceived unmet needs and interactions with primary care. METHODS: Forty long-term survivors of breast, colorectal and prostate cancer were purposively selected for an in-depth qualitative study. We aimed for a maximum variation sample according to cancer site, gender, time since diagnosis, cancer needs, anxiety and depression. Interviews were audio recorded and transcribed verbatim. Transcripts were coded thematically using a grounded theory approach. RESULTS: Analysis of the interview data is presented in four subthemes: the role they perceived for the general practitioner (GP), unmet needs, reasons for not using primary care for needs they perceived as cancer related, and ongoing care for cancer-related issues. The majority of cancer survivors did not see a role for their GP in their long-term care related to their cancer diagnosis as most considered that they did not need active follow-up, but some expressed a need for psychological services and information on possible long-term effects. Cancer survivors cited three main reasons for not using GP services in relation to their cancer diagnosis: GPs were seen as non-experts in cancer; they were perceived as too busy; and a lack of continuity within primary care made it difficult to talk about long-term issues. There was a wide variation in schedules and notification of PSA tests among the prostate cancer survivors. DISCUSSION: The results from this project suggest that some cancer survivors have specific emotional and physical needs that could benefit from input from their primary care team, but not all cancer survivors look to their GP for their long-term cancer-related care. Better information care planning is required from specialists in order to identify those who would benefit mos

Cancer survivors' experiences of using survivorship care plans: a systematic review of qualitative studies

Purpose: Cancer survivorship care plans (SCPs) are currently used in care settings to assist survivors during the transition from treatment to survivorship. In this paper, the experiences of cancer survivors are examined to provide their perspective of how survivorship care plans are used in practice. Methods: A systematic review and critical review of the qualitative literature regarding the experiences of cancer survivors using survivorship care plans was completed. Databases reviewed included CINAHL, AMED, Embase, MEDLINE, Informit, ProQuest, PsycINFO, ScienceDirect, Wiley Online Library, Scopus and Web of Science from 2000 to 2014.ResultsEleven qualitative studies were appraised for methodological quality and content. They revealed four key themes: stakeholders agreed that SCPs should be used as a key strategy for cancer survivors; there was a lack of consensus on the format, content and who should develop the SCP; cancer survivors do not consistently receive SCPs; and there was a lack of evidence to support the use of SCPs in practice. Conclusions: There is great potential for SCPs to assist cancer survivors and this is supported by the range of qualitative literature examined in this study. Further research is required to examine the many practical issues relating to the delivery of SCPs and how they may be used across a variety of care contexts as well as providing further evidence to support their use. Implications for Cancer Survivors: With further research, refinement and contributions made by survivors, health researchers and health care professionals, the survivorship care plan is proposed to be a useful and practical tool aimed at supporting the survivorship continuum of care

Patients' preferences for post-treatment breast cancer follow-up in primary care vs. secondary care:a qualitative study

Objective To explore patients' preferences for follow-up in primary care vs. secondary care. Methods A cross-sectional design was employed, involving semi-structured interviews with 70 female patients with a history of early-stage breast cancer. Using descriptive content analysis, interview transcripts were analysed independently and thematically by two researchers. Findings Patients expressed the strongest preference for annual visits (31/68), a schedule with a decreasing frequency over time (27/68), and follow-up > 10 years, including lifelong follow-up (20/64). The majority (56/61) preferred to receive follow-up care from the same care provider over time, for reasons related to a personal doctor-patient relationship and the physician's knowledge of the patient's history. About 75% (43/56) preferred specialist follow-up to other follow-up models. However, primary care-based follow-up would be accepted by 57% (39/68) provided that there is good communication between GPs and specialists, and sufficient knowledge among GPs about follow-up. Perceived benefits of primary care-based follow-up referred to the personal nature of the GPpatient relationship and the easy access to primary care. Perceived barriers included limited oncology knowledge and skills, time available, motivation among GPs to provide follow-up care and patients' confidence with the present specialist follow-up. Conclusions More than half of the patients were open to primary care-based follow-up. Patients' confidence with this follow-up model may increase by using survivorship care plans to facilitate communication across the primary/secondary interface and with patients. Training GPs to improve their oncology knowledge and skills might also increase patients' confidence

A dyadic approach to understanding the impact of breast cancer on relationships between partners during early survivorship

© 2016 The Author(s). Background: The shared impact of breast cancer for women and their male partners is emerging as an important consideration during the experience of a breast cancer diagnosis, particularly during survivorship. This study aimed to explore the experiences of women and their partners during early survivorship and contributes a range of insights into the lives of those intimately affected by breast cancer. Methods: In-depth interviews were completed with Australian women survivors of breast cancer (n = 8) and their partners (n = 8), between six months and five years following cessation of treatment. Questions included a focus on the women and their partners' daily experiences during early survivorship, including the management of ongoing symptoms, engagement in leisure and social interests, returning to work, communicating with each other, maintenance of the current relationship and other important roles and responsibilities. Thematic analysis was employed to determine key themes arising from the dyadic accounts of women and their partners' experiences during early breast cancer survivorship. Results: Women and their partners experienced many changes to their previous roles, responsibilities and relationships during early breast cancer survivorship. Couples also reported a range of communication, intimacy and sexuality concerns which greatly impacted their interactions with each other, adding further demands on the relationship. Three significant themes were determined: (1) a disconnection within the relationship - this was expressed as the woman survivor of breast cancer needing to prioritise her own needs, sometimes at the expense of her partner and the relationship; (2) reformulating the relationship - this reflects the strategies used by couples to negotiate changes within the relationship; and (3) support is needed to negotiate the future of the relationship - couples emphasised the need for additional support and resources to assist them in maintaining their relationship during early survivorship. Conclusion: It can be concluded that the early survivorship period represents a crucial time for both women and their partners and there are currently limited options available to meet their shared needs and preferences for support. Findings indicate that a suitable model of care underpinned by a biopsychosocial framework, access to comprehensive assessment, timely support and the provision of targeted resources are urgently needed to assist women and their partners during this critical time
