Objective: Up to 50% of women prescribed tamoxifen do not take it as prescribed for the full duration, which increases risk of recurrence and mortality. The current paper describes the development of a self-management intervention aiming to improve adherence in breast cancer survivors taking tamoxifen.

Methods: The intervention was developed following an Intervention Mapping approach. The content of the intervention was determined by theories of health behaviour and empirical evidence. Development was an iterative process involving input from expert researchers, clinicians and patient representatives.

Results: The intervention was designed to improve both intentional and unintentional non-adherence. Key features included modifying unhelpful illness and treatment beliefs, improving confidence for coping with side effects and developing strategies for remembering to take tamoxifen.

Conclusion: Intervention Mapping proved a useful tool for developing an intervention which is grounded in theory and empirical evidence. The intervention has the potential to improve adherence in breast cancer survivors but needs to be trialled before the effectiveness of the intervention can be determined.

Harmony in healthcare: recommended infant feeding practices and associated factors among HIV positive mothers in Eastern Ethiopian hospitals.

J Health Popul Nutr

Department of Health Promotion, School of Public Health, College of Medicine and Health Sciences, Wollo University, Dessie, Ethiopia.

Background: For mothers identified as HIV-infected, recommended infant feeding practices must prioritize the highest likelihood of ensuring HIV-free survival for their children while preserving maternal health. Consequently, understanding the feeding status during critical infancy stages, especially under the risk of HIV, plays a crucial role in enhancing the quality of life within this specific population segment. Hence, this study was conducted to assess the magnitude and associated factors of recommended infant feeding practices and its associated factors among HIV-positive mothers in Eastern Ethiopian Hospitals.

Background: The treatment of metastatic breast cancer (mBC) focuses on prolonging patient survival, providing adequate symptom management, and maintaining quality of life (QoL). This includes supportive therapy to prevent or treat potential side effects and handle comorbidities. The combination of mBC therapy, supportive therapy, and treatment for comorbidities increases the risk for polypharmacy, potential drug-drug interactions (pDDI), potentially inappropriate medication (PIM), and potentially missing drugs (pMD).

Background: Aromatase inhibitors (AI) reduce hormone receptor-positive breast cancer recurrence risk by about 50%. However, half of AI-treated postmenopausal women report new or worsened musculoskeletal symptoms (AIMSS), and 20% discontinue therapy prematurely. Acupuncture is effective for reducing symptoms, but many women are not able to access acupuncture therapy.

Purpose: Interstitial lung disease (ILD) is a well described and potentially fatal complication of trastuzumab-deruxtecan (T-DXd). It is currently unknown if specific monitoring is beneficial in the early detection of ILD in these patients. We describe the efficacy and feasibility of a novel ILD monitoring protocol in breast cancer patients treated with T-DXd at our institution.

Background: Breast cancer represents the most common form of neoplasm in women, with an estimated 685,000 deaths annually. In this regard, screening programmes represent one of the most effective intervention tools in the field of cancer prevention. The aim of this study is to analyse and describe the key performance indicators of the screening programmes in Lombardy from 2016 to 2022.
