Generating monologue and dialogue to present personalised medical information to patients
Tailored Patient Information: Some Issues and Questions
Tailored patient information (TPI) systems are computer programs which
produce personalised heath-information material for patients. TPI systems are
of growing interest to the natural-language generation (NLG) community; many
TPI systems have also been developed in the medical community, usually with
mail-merge technology. No matter what technology is used, experience shows that
it is not easy to field a TPI system, even if it is shown to be effective in
clinical trials. In this paper we discuss some of the difficulties in fielding
TPI systems. This is based on our experiences with 2 TPI systems, one for
generating asthma-information booklets and one for generating smoking-cessation
letters.Comment: This is a paper about technology-transfer. It does not have much

Systematic review and meta-analysis of patient reported outcomes for nurse-led models of survivorship care for adult cancer patients
Purpose: This systematic review aimed to determine the effectiveness of nurse-led cancer survivorship care, compared with existing models of care, on patient reported outcomes for cancer survivors.
Methods: Randomised and non-randomised controlled trials and controlled before-after studies published in English between 1 January 2007 and 28 July 2017 were identified in bibliographic databases including Medline, Pubmed and PsychINFO. Included studies described nurse-led cancer care after treatment to adults (age ≥18 years) \u3c2 years post treatment completion. Risk of bias was assessed using Joanna Briggs Institute’s tools and meta-analysis was undertaken.
Results: Twenty one publications were included describing 15 tumour-specific trials involving 3278 survivors of breast (n = 5), gynecological (n = 3), head and neck (n = 2), colorectal (n = 2), upper gastrointestinal (n = 2) and prostate (n = 1) cancers. Seven trials reported quality of life (QoL) using the EORTC QLQ-C30; participants receiving nurse-led care (4–6 months) had better cognitive (4 trials, 463 participants; mean difference [MD] = 4.04 [95% CI, 0.59–7.50]; p = 0.02) and social functioning (4 trials, 463 participants; MD = 3.06 [0.14–5.97]; p = 0.04) but worse appetite loss (3 trials, 354 participants; MD = 4.43 [0.08–8.78]; p = 0.05). After intervention completion, intervention participants had reduced fatigue (4 trials, 647 participants; MD = −4.45 [−7.93 to −0.97]; p = 0.01).
Conclusion: This systematic review synthesised outcomes of models of nurse-led survivorship care and contributes a meta-analysis of patient QoL to survivorship evidence. This review was limited by the risk of bias in many included studies for blinding of treatment personnel and outcome assessors. Nurse-led care appears beneficial for cancer survivors for some QoL domains
Key environmental stress biomarker candidates for the optimisation of chemotherapy treatment of leukaemia
The impact of fluctuations of environmental parameters
such as oxygen and starvation on the evolution of leukaemia
is analysed in the current review. These fluctuations may occur
within a specific patient (in different organs) or across patients
(individual cases of hypoglycaemia and hyperglycaemia). They
can be experienced as stress stimuli by the cancerous population,
leading to an alteration of cellular growth kinetics, metabolism
and further resistance to chemotherapy. Therefore, it is of high
importance to elucidate key mechanisms that affect the evolution
of leukaemia under stress. Potential stress response mechanisms
are discussed in this review. Moreover, appropriate cell biomarker
candidates related to the environmental stress response and/or
further resistance to chemotherapy are proposed. Quantification
of these biomarkers can enable the combination of macroscopic kinetics
with microscopic information, which is specific to individual
patients and leads to the construction of detailed mathematical
models for the optimisation of chemotherapy. Due to their nature,
these models will be more accurate and precise (in comparison
to available macroscopic/black box models) in the prediction of
responses of individual patients to treatment, as they will incorporate
microscopic genetic and/or metabolic information which is
patient-specific.peer-reviewe
Reducing dementia risk by targeting modifiable risk factors in mid-life: study protocol for the Innovative midlife intervention for dementia deterrence (In-MINDD) randomised controlled feasibility trial
Background
Dementia prevalence is increasing as populations live longer, with no cure and the costs of caring exceeding many other conditions. There is increasing evidence for modifiable risk factors which, if addressed in mid-life, can reduce the risk of developing dementia in later life. These include physical inactivity, low cognitive activity, mid-life obesity, high blood pressure, and high cholesterol. This study aims to assess the acceptability and feasibility and impact of giving those in mid-life, aged between 40 and 60 years, an individualised dementia risk modification score and profile and access to personalised on-line health information and goal setting in order to support the behaviour change required to reduce such dementia risk. A secondary aim is to understand participants’ and practitioners’ views of dementia prevention and explore the acceptability and integration of the Innovative Midlife Intervention for Dementia Deterrence (In-MINDD) intervention into daily life and routine practice.
Methods/design
In-MINDD is a multi-centre, primary care-based, single-blinded randomised controlled feasibility trial currently being conducted in four European countries (France, Ireland, the Netherlands and the UK). Participants are being recruited from participating general practices. Inclusion criteria will include age between 40 and 60 years; at least one modifiable risk factor for dementia risk (including diabetes, hypertension, obesity, renal dysfunction, current smoker, raised cholesterol, coronary heart disease, current or previous history of depression, self-reported sedentary lifestyle, and self-reported low cognitive activity) access to the Internet. Primary outcome measure will be a change in dementia risk modification score over the timescale of the trial (6 months). A qualitative process evaluation will interview a sample of participants and practitioners about their views on the acceptability and feasibility of the trial and the links between modifiable risk factors and dementia prevention. This work will be underpinned by Normalisation Process Theory.
Discussion
This study will explore the feasibility and acceptability of a risk profiler and on-line support environment to help individuals in mid-life assess their risk of developing dementia in later life and to take steps to alleviate that risk by tackling health-related behaviour change. Testing the intervention in a robust and theoretically informed manner will inform the development of a future, full-scale randomised controlled trial
On the road to personalised and precision geomedicine: medical geology and a renewed call for interdisciplinarity
Our health depends on where we currently live, as well as on where we have lived in the past and for how long in each place. An individual’s place history is particularly relevant in conditions with long latency between exposures and clinical manifestations, as is the case in many types of cancer and chronic conditions. A patient’s geographic history should routinely be considered by physicians when diagnosing and treating individual patients. It can provide useful contextual environmental information (and the corresponding health risks) about the patient, and should thus form an essential part of every electronic patient/health record. Medical geology investigations, in their attempt to document the complex relationships between the environment and human health, typically involve a multitude of disciplines and expertise. Arguably, the spatial component is the one factor that ties in all these disciplines together in medical geology studies. In a general sense, epidemiology, statistical genetics, geoscience, geomedical engineering and public and environmental health informatics tend to study data in terms of populations, whereas medicine (including personalised and precision geomedicine, and lifestyle medicine), genetics, genomics, toxicology and biomedical/health informatics more likely work on individuals or some individual mechanism describing disease. This article introduces with examples the core concepts of medical geology and geomedicine. The ultimate goals of prediction, prevention and personalised treatment in the case of geology-dependent disease can only be realised through an intensive multiple-disciplinary approach, where the various relevant disciplines collaborate together and complement each other in additive (multidisciplinary), interactive (interdisciplinary) and holistic (transdisciplinary and cross-disciplinary) manners
High frequency of pathogenic non-founder germline mutations in BRCA1 and BRCA2 in families with breast and ovarian cancer in a founder population
Funding Information: This work was supported by State Research Program “Biomedicine for the public health (BIOMEDICINE)” project 5 “Personalised cancer diagnostics and treatment effectiveness evaluation”. Publisher Copyright: © 2018 The Author(s).Background: Pathogenic BRCA1 founder mutations (c.4035delA, c.5266dupC) contribute to 3.77% of all consecutive primary breast cancers and 9.9% of all consecutive primary ovarian cancers. Identifying germline pathogenic gene variants in patients with primary breast and ovarian cancer could significantly impact the medical management of patients. The aim of the study was to evaluate the rate of pathogenic mutations in the 26 breast and ovarian cancer susceptibility genes in patients who meet the criteria for BRCA1/2 testing and to compare the accuracy of different selection criteria for second-line testing in a founder population. Methods: Fifteen female probands and 1 male proband that met National Comprehensive Cancer Network (NCCN) criteria for BRCA1/2 testing were included in the study and underwent 26-gene panel testing. Fourteen probands had breast cancer, one proband had ovarian cancer, and one proband had both breast and ovarian cancer. In a 26-gene panel, the following breast and/or ovarian cancer susceptibility genes were included: ATM, BARD1, BLM, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM, FAM175A, MEN1, MLH1, MRE11A, MSH2, MSH6, MUTYH, NBN, PALB2, PMS2, PTEN, RAD50, RAD51C, RAD51D, STK11, TP53, and XRCC2. All patients previously tested negative for BRCA1 founder mutations. Results: In 44% (7 out of 16) of tested probands, pathogenic mutations were identified. Six probands carried pathogenic mutations in BRCA1, and one proband carried pathogenic mutations in BRCA2. In patients, a variant of uncertain significance was found in BRCA2, RAD50, MRE11A and CDH1. The Manchester scoring system showed a high accuracy (87.5%), high sensitivity (85.7%) and high specificity (88.9%) for the prediction of pathogenic non-founder BRCA1/2 mutations. Conclusion: A relatively high incidence of pathogenic non-founder BRCA1/2 mutations was observed in a founder population. The Manchester scoring system predicted the probability of non-founder pathogenic mutations with high accuracy.publishersversionPeer reviewe
Ensuring sample quality for biomarker discovery studies - Use of ict tools to trace biosample life-cycle
The growing demand of personalized medicine marked the transition from an empirical medicine to a molecular one, aimed at predicting safer and more effective medical treatment for every patient, while minimizing adverse effects. This passage has emphasized the importance of biomarker discovery studies, and has led sample availability to assume a crucial role in biomedical research. Accordingly, a great interest in Biological Bank science has grown concomitantly. In biobanks, biological material and its accompanying data are collected, handled and stored in accordance with standard operating procedures (SOPs) and existing legislation. Sample quality is ensured by adherence to SOPs and sample whole life-cycle can be recorded by innovative tracking systems employing information technology (IT) tools for monitoring storage conditions and characterization of vast amount of data. All the above will ensure proper sample exchangeability among research facilities and will represent the starting point of all future personalized medicine-based clinical trials
