Introduction Significant number of women present with advanced-stage breast cancer in Ghana. These women usually depend on family caregivers for their multi-dimensional needs. Yet, there are gaps in research about what motivates family caregivers to assume the caring role and their experiences with caregiving within the Ghanaian context. Aim To explore and describe the caregiving motivations and experiences among family caregivers of patients living with advanced breast cancer. Methods In-depth, semi-structured qualitative interviews were conducted with 15 family caregivers who were providing unpaid care for women living with advanced breast cancer. Colaizzi's thematic analysis was used to analyze the data. Results Family relationship normally prescribed the caregiving role among family caregivers. Due to the lack of home-based palliative services in Ghana, findings suggest that family caregivers are the main managers of advanced breast cancer-related symptoms in the home. These findings are discussed under three major themes: (i) motivation for assuming the caregiving role; (ii) meeting self-care and psychosocial needs of the patient; and (iii) symptom management and monitoring. Conclusion Socio-cultural values influence the role of family caregivers in Ghana. This presents opportunities for health professionals and relevant stakeholders to develop a culturally-PLOS ONE

Introduction: Caregivers of women with breast cancer in low-and-middle-income countries experience significant physical and economic burdens. The review aimed to map the evidence of studies that had reported on the experiences of family caregivers of women diagnosed with breast cancer. Methods: A systematic literature search was conducted in CINAHL, PubMed, PsycINFO, Scopus, and Web of Science databases using a combination of key search terms and medical subject heading terms such as "family caregiver," "breast cancer," "home care," "low-and-middle-income countries," "experience," "effect," and "coping mechanism." A total of 1781 articles were retrieved and screened. Nineteen studies addressing caregiving experiences were included in the final review based on the inclusion and exclusion criteria. Results: The systematic review yielded 19 studies that focused on caregivers' motivation, needs of caregivers, intervention for caregivers, and consequences of caregiving. The most significant correlates of the quality of life among caregivers were disease severity, functional status of patients, and family income. The challenges encountered by caregivers were mostly psychosocial. Conclusions: Caregivers play a crucial role in the management of women with breast cancer. However, they are faced with increasing challenges in their caregiving roles. Understanding the nature and extent of the burden experienced by family caregivers in developing countries will facilitate the development of appropriate interventions that can help improve caregivers' quality of life. Gaps in recent studies were identified, and suggestions for future research were also addressed in this review. Systematic review registration: PROSPERO CRD42019118391

Pathogenic microorganisms often have the ability to attach to a surface, building a complex matrix where they colonize to form a biofilm. This cellular superstructure can display increased resistance to antibiotics and cause serious, persistent health problems in humans. Here we describe a high-throughput in vitro screen to identify inhibitors of Acinetobacter baumannii biofilms using a library of natural product extracts derived from marine microbes. Analysis of extracts derived from Streptomyces gandocaensis results in the discovery of three peptidic metabolites (cahuitamycins A–C), with cahuitamycin C being the most effective inhibitor (IC50=14.5 μM). Biosynthesis of cahuitamycin C proceeds via a convergent biosynthetic pathway, with one of the steps apparently being catalysed by an unlinked gene encoding a 6-methylsalicylate synthase. Efforts to assess starter unit diversification through selective mutasynthesis lead to production of unnatural analogues cahuitamycins D and E of increased potency (IC50=8.4 and 10.5 μM).
