BackgroundDespite increased efforts to control and ultimately eradicate human malaria, Plasmodium ovale malaria is for the most part outside the focus of research or public health programmes. Importantly, the understanding of P. ovale—nowadays regarded as the two distinct species P. ovale wallikeri and P. ovale curtisi—largely stems from case reports and case series lacking study designs providing high quality evidence. Consecutively, there is a lack of systematic evaluation of the clinical presentation, appropriate treatment and relapse characteristics of P. ovale malaria. The aim of this systematic review is to provide a systematic appraisal of the current evidence for severe manifestations, relapse characteristics and treatment options for human P. ovale malaria.Methods and resultsThis systematic review was performed according to the PRISMA guidelines and registered in the international prospective register for systematic reviews (PROSPERO 2016:CRD42016039214). P. ovale mono-infection was a strict inclusion criterion. Of 3454 articles identified by the literature search, 33 articles published between 1922 and 2015 met the inclusion criteria. These articles did not include randomized controlled trials. Five prospective uncontrolled clinical trials were performed on a total of 58 participants. P. ovale was sensitive to all tested drugs within the follow-up periods and on interpretable in vitro assays. Since its first description in 1922, only 18 relapsing cases of P. ovale with a total of 28 relapse events were identified in the scientific literature. There was however no molecular evidence for a causal relationship between dormant liver stages and subsequent relapses. A total of 22 severe cases of P. ovale malaria were published out of which five were fatal. Additionally, two cases of congenital P. ovale malaria were reported.ConclusionsCurrent knowledge of P. ovale malaria is based on small trials with minor impact, case reports and clinical observations. This systematic review highlights that P. ovale is capable of causing severe disease, severe congenital malaria and may even lead to death. Evidence for relapses in patients with P. ovale malaria adds up to only a handful of cases. Nearly 100 years after P. ovale’s first description by Stephens the evidence for the clinical characteristics, relapse potential and optimal treatments for P. ovale malaria is still scarce.Electronic supplementary materialThe online version of this article (doi:10.1186/s12936-017-1759-2) contains supplementary material, which is available to authorized users.

Background Women with BRCA1/2 mutations are at high risk to develop breast and ovarian cancer. To support these women to participate in shared decision-making, structured nurse-led decision coaching combined with an evidence-based decision aid may be employed. In preparation of the interprofessional randomized controlled trial to evaluate a decision coaching program to support preventive decisions of healthy female BRCA 1/2 gene mutation carriers (EDCP-BRCA), we adapted and piloted an existing training program for specialized nurses and included elements from an existing physician communication training. Methods The training was adapted according to the six-step-approach for medical curriculum development. The educational design is based on experience- and problem-based learning. Subsequently, we conducted a qualitative pilot study. Nurses were recruited from six German centers for familial breast and ovarian cancer. The acceptability and feasibility were assessed by structured class observations, field notes and participants’ feedback. Data were analyzed using qualitative content analysis. The training was revised according to the results. Due to the COVID-19 pandemic, the patient intervention was adapted as a virtual coaching and a brief additional training for nurses was added. Results The training consists of two modules (2 + 1 day) that teach competences in evidence-based medicine and patient information, (risk) communication and decision coaching. One pilot test was conducted with six nurses of which three were specialized and experienced in patient counselling. A final set of eight main categories was derived from the data: framework conditions; interaction; schedule, transparency of goals, content, methods, materials and practical relevance and feasibility. Overall, the training was feasible and comprehensible. Decision coaching materials were awkward to handle and decision coaching role plays were set too short. Therefore, materials will be sent out in advance and the training was extended. Conclusions Specialized nurses are rarely available and nurse-led counselling is not routinely implemented in the centers of familial breast and ovarian cancer. However, training of less qualified nurses seems feasible. Decision coaching in a virtual format seems to be a promising approach. Further research is needed to evaluate its feasibility, acceptability and effectiveness. Trial registration The main trial is registered under DRKS-ID: DRKS00015527.

Background: Female BRCA mutation carriers have an increased lifetime risk for breast and ovarian cancer compared to the general population. Women who carry this mutation have several options to deal with their cancer risk, such as risk-reducing surgeries or intensified breast cancer screening. Previous research has shown that preferences in this scenario are highly dependent on affected women's personalities and value systems. To support these women in the decision-making process, a structured decision support consisting of decision coaching combined with a decision aid might be helpful. Methods/design: A randomized controlled trial will be conducted in order to compare usual care with structured decision support alongside usual care. The decision support program entails nurse-led decision coaching as well as an evidence-based patient decision aid. Nurses are qualified by a 4-day training program in informed decisionmaking and decision coaching. Six centers for Familial Breast and Ovarian Cancer in Germany will be included in the study, with a planned sample size of 398 women. The primary outcome is the congruence between the preferred and the actual played role in the decision-making process as measured by the Control Preferences Scale. It is hypothesized that the structured decision support will enable women to play the preferred role in the decision-making process. Secondary outcomes include the knowledge and attitudes about preventive options, decisional conflict, depression and anxiety, coping self-efficacy, impact of event, and self-concept. A process evaluation will accompany the study. Discussion: The EDCP-BRCA study is the first study to implement and evaluate decision coaching combined with a decision aid for healthy BRCA mutation carriers worldwide.
