Breast cancer is associated with adverse physical and psychological consequences. Although research has identified the various benefits linked to psychosocial interventions, mixed results have been found in relation to peer support. The aim of the present systematic review and meta‐ethnography is to explore the qualitative evidence on the experience of breast cancer survivors in peer support. A systematic search of the literature was conducted until June 2023, and a meta‐ethnographic approach was used to synthesize the included papers. Eleven articles were included, collecting the experience of 345 participants. The following four core areas involved in peer support implementation were identified from the synthesis: Peer support can create understanding and a mutual therapeutic and emotional connection; peer support can facilitate an educational and supportive patient‐centered journey; peer support should monitor group members for unpleasant emotional experiences; peer support should have professional supervision of recruitment and training to prioritize quality. These results can be used as patient‐centered insights by healthcare professionals to provide evidence‐informed peer support programs and address current limitations in the field.

Simple Summary: With the recent increase in survival rates of breast cancer patients, it is of key importance to also improve their life quality. Disinformation regarding illness is one of the major stress sources for patients with breast cancer. The present study aimed to study the educational section of the digital ecosystem ICOnnecta't, analyzing which health information areas are most relevant for breast cancer patients. The fact that patients mostly consulted emotional and medical audiovisual material within the first three months after diagnosis underlines the need to create significant health-related content and deliver it to patients shortly after diagnosis. Those preventive interventions are essential to avoid the deterioration of emotional distress, which in turn has been shown to influence, not only life quality, but also patient survival. Health education and psychosocial interventions prevent emotional distress, and the latter has been shown to have an impact on survival. In turn, digital health education interventions may help promote equity by reaching a higher number of cancer patients, both because they avoid journeys to the hospital, by and having a better efficiency. A total of 234 women recently diagnosed with breast cancer in a comprehensive cancer center used the digital ecosystem ICOnnecta't from March 2019 to March 2021. ICOnnecta't consists of four care levels, provided to patients according to their level of distress. The second level of this intervention consists of an educational campus, which was analyzed to track users' interests and their information-seeking behavior. Overall, 99 out of 234 women (42.3%) used the educational campus. There were no significant differences in sociodemographic and clinical variables between the campus users and non-users. Among users, the median number of resources utilized per user was four (interquartile range: 2–9). Emotional and medical resources were the contents most frequently viewed and the audiovisual format the most consulted (p < 0.01). Resources were used mainly within the first three months from enrolment. Users who were guided to visit the virtual campus were more active than spontaneous users. Offering an early holistic health educational platform inside a digital cancer ecosystem, with health professionals involved, can reach more patients, promoting equity in the access of cancer information and prevention, from the very beginning of the disease.

Background: Breast cancer is one of the most prevalent diseases in women. Prevention and treatments have lowered mortality; nevertheless, the impact of the diagnosis and treatment continue to impact all aspects of patients' lives (physical, emotional, cognitive, social, and spiritual). Objective: This study seeks to explore the experiences of the different stages women with breast cancer go through by means of a patient journey. Methods: This is a qualitative study in which 21 women with breast cancer or survivors were interviewed. Participants were recruited at 9 large hospitals in Spain and intentional sampling methods were applied. Data were collected using a semi-structured interview that was elaborated with the help of medical oncologists, nurses, and psycho-oncologists. Data were processed by adopting a thematic analysis approach. Results: The diagnosis and treatment of breast cancer entails a radical change in patients' day-to-day that linger in the mid-term. Seven stages have been defined that correspond to the different medical processes: diagnosis/unmasking stage, surgery/cleaning out, chemotherapy/loss of identity, radiotherapy/transition to normality, follow-up care/the "new" day-to-day, relapse/starting over, and metastatic/time-limited chronic breast cancer. The most relevant aspects of each are highlighted, as are the various cross-sectional aspects that manifest throughout the entire patient journey. Conclusions: Comprehending patients' experiences in depth facilitates the detection of situations of risk and helps to identify key moments when more precise information should be offered. Similarly, preparing the women for the process they must confront and for the sequelae of medical treatments would contribute to decreasing their uncertainty and concern, and to improving their quality-of-life.

Background/objective: The impact a cancer diagnosis and its treatment are affected by psychosocial factors and how these factors interrelate among themselves. The objective of this study was to analyze the relationship between optimism and social support in spiritual wellbeing in cancer patients initiating chemotherapy. Methods: A cross-sectional, multi-center (15 sites), prospective study was conducted with 912 cancer patients who had undergone curative surgery for a stage I–III cancer and were to receive adjuvant chemotherapy. They completed the Functional Assessment of Chronic Illness-Spiritual Well-being Scale (FACIT-Sp), Life Orientation Test-Revised (LOT-R), and the Multidimensional Scale of Perceived Social Support (MSPSS). Results: Significant differences on spirituality scales (meaning/peace and faith) were detected depending on age (≤ 65 vs > 65), sex, marital status, employment, and cancer treatment. Married or partnered participants had significantly higher meaning/peace scores compared to their non-partnered counterparts (p = 0.001). Women, > 65 years, unemployed, and patients treated with chemotherapy and radiotherapy had significantly higher faith scores versus men, ≤ 65 years, employed, and subjects only receiving adjuvant chemotherapy (all p < 0.030). Multivariate analyses indicated that meaning/peace and faith correlated positively with optimism and social support. Conclusion: During oncological treatment, the positive effects of optimism and social support exhibit a positive correlation with spiritual coping. A brief assessment evaluation of these factors can aid in identifying at risk for a worse adaptation to the disease. [ABSTRACT FROM AUTHOR]

Background: The current cancer care system must be improved if we are to have in-depth knowledge about breast cancer patients' experiences throughout all the stages of their disease. Aim: This study seeks to describe breast cancer patients' experience over the course of the various stages of illness by means of a journey model. Methods: This is a qualitative descriptive study. Individual, semi-structured interviews will be administered to women with breast cancer and breast cancer survivors. Patients will be recruited from nine large hospitals in Spain and intentional sampling will be used. Data will be collected by means of a semi-structured interview that was elaborated with the help of medical oncologists, nurses, and psycho-oncologists. Data will be processed adopting a thematic analysis approach. Discussion: The outcomes of this study will afford new insights into breast cancer patients' experiences, providing guidance to improve the care given to these individuals. This protocol aims to describe the journey of patients with breast cancer through the healthcare system to establish baseline data that will serve as the basis for the development and implementation of a patient-centered, evidence-based clinical pathway.

Shared decision-making regarding adjuvant systemic therapy in breast cancer is based on both properly conveying information about the prognosis of the disease and the benefits and risks of adjuvant treatment, as well as the patient's ability to understand this information. This work proposed to analyze oncologists' and patients' perceptions of the risk of recurrence with and without chemotherapy and toxicity, and the factors influencing said impressions. This was a prospective, cross-sectional, multicenter study that involved 281 breast cancer patients and 23 oncologists. Prognosis (risk of recurrence with and without chemotherapy and risk of severe toxicity with chemotherapy) and shared decision making (SDM) questionnaires were completed by all participants; breast cancer patients also filled out the 18-item Brief Symptom Inventory (BSI-18). Oncologists' prediction of risk of relapse without and with chemotherapy (30.4 and 13.3%) and risk of severe toxicity (9.8%) were more optimistic than those of breast cancer patients (78.6, 29.6, and 61%, respectively). The greater the severity, the higher the risk of relapse according to the oncologists (p = 0.001); not so for the patients. Older physicians and more experienced ones predicted lower risk of relapse with and without chemotherapy and less severe toxicity than younger doctors and those with less experience (p < 0.001). Oncologists' SDM and their prediction of risk of relapsing with chemotherapy correlated negatively with patients' SDM and their prediction of risk of severe toxicity (p < 0.01). There is a positive correlation between psychological distress (BSI-18) and prognosis of risk of recurrence with chemotherapy in breast cancer patients (p < 0.001). These results stress the importance of improving doctor–patient communication in SDM. In breast cancer patients undergoing treatment with curative intent, expectations of being cured would increase and treatment-related anxiety would decrease by enhancing doctor–patient communication to coincide more with respect to risk of relapse and toxicity, thereby enhancing patients' quality of life.

The dual-specificity tyrosine phosphorylation-regulated kinase DYRK1A is a serine/threonine kinase involved in neuronal differentiation and synaptic plasticity and a major candidate of Down syndrome brain alterations and cognitive deficits. DYRK1A is strongly expressed in the cerebral cortex, and its overexpression leads to defective cortical pyramidal cell morphology, synaptic plasticity deficits, and altered excitation/inhibition balance. These previous observations, however, do not allow predicting how the behavior of the prefrontal cortex (PFC) network and the resulting properties of its emergent activity are affected. Here, we integrate functional, anatomical, and computational data describing the prefrontal network alterations in transgenic mice overexpressing Dyrk1A (TgDyrk1A). Using in vivo extracellular recordings, we show decreased firing rate and gamma frequency power in the prefrontal network of anesthetized and awake TgDyrk1A mice. Immunohistochemical analysis identified a selective reduction of vesicular GABA transporter punctae on parvalbumin positive neurons, without changes in the number of cortical GABAergic neurons in the PFC of TgDyrk1A mice, which suggests that selective disinhibition of parvalbumin interneurons would result in an overinhibited functional network. Using a conductance-based computational model, we quantitatively demonstrate that this alteration could explain the observed functional deficits including decreased gamma power and firing rate. Our results suggest that dysfunction of cortical fast-spiking interneurons might be central to the pathophysiology of Down syndrome. [ABSTRACT FROM AUTHOR]
