- OBJECTIVE: To evaluate the attitudes to and adoption of dietary advice in nondiabetic first-degree relatives of patients with type 2 diabetes and to examine barriers to adherence. DESIGN: One-year controlled intervention study, where treatment group (n=73) received lifestyle education. Attitudes towards dietary advice, change in dietary habits and importance of potential barriers to adherence were evaluated by questionnaires. Nondiabetic relatives (25-55 years; males and females) of individuals with type 2 diabetes were recruited. Education was based on current nutrition recommendations and aimed at improving dietary fat quality, increasing intake of fruit and vegetables, with additional advice to reduce dietary glycaemic index (GI). MAIN OUTCOME MEASURES: Attitudes and importance of barriers were classified by the intervened subjects into four categories ranging from 'No problem' to 'Yes, definitely a problem'. Dietary adherence was monitored by food frequency questionnaire at baseline and after 1 year. RESULTS: Participants were generally in favour of advice aimed at improving dietary fat quality. Attitudes towards advice to reduce GI varied widely. Food selection changed in accordance with predefined dietary goals. 'Forgetfulness', 'low availability in lunch restaurant' and 'lack of ideas for cooking' were barriers to adherence. CONCLUSIONS: Dietary advice aimed at reducing risk of type 2 diabetes was generally positively received and adopted in subjects with heredity for the disease. The most prevalent barriers reported are potentially modifiable.

Journal article (peer-reviewed)abstract
- PURPOSE: The purpose of this study was to identify genetic aberrations contributing to clinical aggressiveness of malignant peripheral nerve sheath tumors (MPNSTs). PATIENTS AND METHODS: Samples from 48 MPNSTs and 10 neurofibromas were collected from 51 patients with (n = 31) or without (n = 20) neurofibromatosis type 1 (NF1). Genome-wide DNA copy number changes were assessed by chromosomal and array-based comparative genomic hybridization (CGH) and examined for prognostic significance. For a subset of 20 samples, RNA microarray data were integrated with the genome data to identify potential target genes. RESULTS: Forty-four (92%) MPNSTs displayed DNA copy number changes (median, 18 changes per tumor; range, 2 to 35 changes). Known frequent chromosomal gains at chromosome arms 8q (69%), 17q (67%), and 7p (52%) and losses from 9p (50%), 11q (48%), and 17p (44%) were confirmed. Additionally, gains at 16p or losses from 10q or Xq identified a high-risk group with only 11% 10-year disease-specific survival (P = .00005). Multivariate analyses including NF1 status, tumor location, size, grade, sex, complete remission, and initial metastatic status showed that the genomic high-risk group was the most significant predictor of poor survival. Several genes whose expression was affected by the DNA copy number aberrations were identified. CONCLUSION: The presence of specific genetic aberrations was strongly associated with poor survival independent of known clinical risk factors. Conversely, within the total patient cohort with 34% 10-year disease-specific survival, a low-risk group was identified: without changes at chromosomes 10q, 16p, or Xq in their MPNSTs, the patients had 74% 10-year survival.

Exploring why European primary care physicians sometimes do not think of, or act on, a possible cancer diagnosis : a qualitative study
- 2023
-
In: BJGP Open. - : Royal College of General Practitioners. - 2398-3795. ; 7:4
-
Journal article (peer-reviewed)abstract
- Background: While primary care physicians (PCPs) play a key role in cancer detection, they can find cancer diagnosis challenging, and some patients have considerable delays between presentation and onward referral.Aim: To explore European PCPs’ experiences and views on cases where they considered that they had been slow to think of, or act on, a possible cancer diagnosis.Design & setting: A multicentre European qualitative study, based on an online survey with open-ended questions, asking PCPs for their narratives about cases when they had missed a diagnosis of cancer.Method: Using maximum variation sampling, PCPs in 23 European countries were asked to describe what happened in a case where they were slow to think of a cancer diagnosis, and for their views on why it happened. Thematic analysis was used to analyse the data.Results: A total of 158 PCPs completed the questionnaire. The main themes were as follows: patients’ descriptions did not suggest cancer; distracting factors reduced PCPs’ cancer suspicions; patients’ hesitancy delayed the diagnosis; system factors not facilitating timely diagnosis; PCPs felt that they had acted wrongly; and problems with communicating adequately.Conclusion: The study identified six overarching themes that need to be addressed. Doing so should reduce morbidity and mortality in the small proportion of patients who have a significant, avoidable delay in their cancer diagnosis. The ‘Swiss cheese’ model of accident causation showed how the themes related to each other.

Journal article (peer-reviewed)abstract
- Background National European cancer survival rates vary widely. Prolonged diagnostic intervals are thought to be a key factor in explaining these variations. Primary care practitioners (PCPs) frequently play a crucial role during initial cancer diagnosis; their knowledge could be used to improve the planning of more effective approaches to earlier cancer diagnosis. Objectives This study sought the views of PCPs from across Europe on how they thought the timeliness of cancer diagnosis could be improved. Design In an online survey, a final open-ended question asked PCPs how they thought the speed of diagnosis of cancer in primary care could be improved. Thematic analysis was used to analyse the data. Setting A primary care study, with participating centres in 20 European countries. Participants A total of 1352 PCPs answered the final survey question, with a median of 48 per country. Results The main themes identified were: patient-related factors, including health education; care provider-related factors, including continuing medical education; improving communication and interprofessional partnership, particularly between primary and secondary care; factors relating to health system organisation and policies, including improving access to healthcare; easier primary care access to diagnostic tests; and use of information technology. Re-allocation of funding to support timely diagnosis was seen as an issue affecting all of these. Conclusions To achieve more timely cancer diagnosis, health systems need to facilitate earlier patient presentation through education and better access to care, have well-educated clinicians with good access to investigations and better information technology, and adequate primary care cancer diagnostic pathway funding.

Journal article (peer-reviewed)abstract
- OBJECTIVES: Cancer survival and stage of disease at diagnosis and treatment vary widely across Europe. These differences may be partly due to variations in access to investigations and specialists. However, evidence to explain how different national health systems influence primary care practitioners' (PCPs') referral decisions is lacking.This study analyses health system factors potentially influencing PCPs' referral decision-making when consulting with patients who may have cancer, and how these vary between European countries.DESIGN: Based on a content-validity consensus, a list of 45 items relating to a PCP's decisions to refer patients with potential cancer symptoms for further investigation was reduced to 20 items. An online questionnaire with the 20 items was answered by PCPs on a five-point Likert scale, indicating how much each item affected their own decision-making in patients that could have cancer. An exploratory factor analysis identified the factors underlying PCPs' referral decision-making.SETTING: A primary care study; 25 participating centres in 20 European countries.PARTICIPANTS: 1830 PCPs completed the survey. The median response rate for participating centres was 20.7%.OUTCOME MEASURES: The factors derived from items related to PCPs' referral decision-making. Mean factor scores were produced for each country, allowing comparisons.RESULTS: Factor analysis identified five underlying factors: PCPs' ability to refer; degree of direct patient access to secondary care; PCPs' perceptions of being under pressure; expectations of PCPs' role; and extent to which PCPs believe that quality comes before cost in their health systems. These accounted for 47.4% of the observed variance between individual responses.CONCLUSIONS: Five healthcare system factors influencing PCPs' referral decision-making in 20 European countries were identified. The factors varied considerably between European countries. Knowledge of these factors could assist development of health service policies to produce better cancer outcomes, and inform future research to compare national cancer diagnostic pathways and outcomes.

- OBJECTIVES: Cancer survival rates vary widely between European countries, with differences in timeliness of diagnosis thought to be one key reason. There is little evidence on the way in which different healthcare systems influence primary care practitioners' (PCPs) referral decisions in patients who could have cancer.This study aimed to explore PCPs' diagnostic actions (whether or not they perform a key diagnostic test and/or refer to a specialist) in patients with symptoms that could be due to cancer and how they vary across European countries. DESIGN: A primary care survey. PCPs were given vignettes describing patients with symptoms that could indicate cancer and asked how they would manage these patients. The likelihood of taking immediate diagnostic action (a diagnostic test and/or referral) in the different participating countries was analysed. Comparisons between the likelihood of taking immediate diagnostic action and physician characteristics were calculated. SETTING: Centres in 20 European countries with widely varying cancer survival rates. PARTICIPANTS: A total of 2086 PCPs answered the survey question, with a median of 72 PCPs per country. RESULTS: PCPs' likelihood of immediate diagnostic action at the first consultation varied from 50% to 82% between countries. PCPs who were more experienced were more likely to take immediate diagnostic action than their peers. CONCLUSION: When given vignettes of patients with a low but significant possibility of cancer, more than half of PCPs across Europe would take diagnostic action, most often by ordering diagnostic tests. However, there are substantial between-country variations.

Short-term outcome after open-heart surgery for severe chronic rheumatic heart disease in a low-income country, with comparison with an historical control group: an observational study
- 2021
-
In: Open heart. - : BMJ PUBLISHING GROUP. - 2053-3624. ; 8:2
-
Journal article (peer-reviewed)abstract
- Objectives Rheumatic heart disease (RHD) is a major burden in low-income and middle-income countries (LMICs). Cardiac surgery is the only curative treatment. Little is known about patients with severe chronic RHD operated in LMICs, and challenges regarding postoperative follow-up are an important issue. At Tikur Anbessa Specialised Hospital, Addis Ababa, Ethiopia, we aimed to evaluate the course and 12-month outcome of patients with severe chronic RHD who received open-heart surgery, as compared with the natural course of controls waiting for surgery and undergoing only medical treatment. Methods Clinical data and outcome measures were registered in 46 patients operated during five missions from March 2016 to November 2019, and compared with the first-year course in a cohort of 49 controls from the same hospitals waiting list for surgery. Adverse events were death or complications such as stroke, other thromboembolic events, bleeding, hospitalisation for heart failure and infectious endocarditis. Results Survival at 12 months was 89% and survival free from complications was 80% in the surgical group. Despite undergoing open-heart surgery, with its inherent risks, outcome measures of the surgical group were non-inferior to the natural course of the control group in the first year after inclusion on the waiting list (p >= 0.45). All except six surgical patients were in New York Heart Association class I after 12 months and 84% had resumed working. Conclusions Cardiac surgery for severe chronic RHD is feasible in LMICs if the service is structured and planned. Rates of survival and survival free from complications were similar to those of controls at 12 months. Functional level and resumption of work were high in the surgical group. Whether the patients who underwent cardiac surgery will have better long-term prognosis, in line with what is known in high-income countries, needs to be evaluated in future studies.

- Objective: Needle acupuncture in small children has gained some acceptance in Western medicine. It is controversial, as infants and toddlers are unable to consent to treatment. We aimed to assess its efficacy for treating infantile colic. Design: A systematic review and a blinding-test validation based on individual patient data from randomised controlled trials. Primary end-points were crying time at mid-treatment, at the end of treatment and at a 1-month follow-up. A 30-min mean difference (MD) in crying time between acupuncture and control was predefined as a clinically important difference. Pearson’s chi-squared test and the James and Bang indices were used to test the success of blinding of the outcome assessors [parents]. Eligibility criteria and data sources: We included randomised controlled trials of acupuncture treatments of infantile colic. Systematic searches were conducted in Cochrane CENTRAL, MEDLINE, EMBASE, CINAHL and AMED, and in the Chinese language databases CNKI, VIP, Wang fang, SinoMed and Chinese Clinical Trial Registry. Results: We included three randomised controlled trials with data from 307 participants. Only one of the included trials obtained a successful blinding of the outcome assessors in both the acupuncture and control groups. The MD in crying time between acupuncture intervention and no acupuncture control was −24.9 min [95% confidence interval, CI −46.2 to −3.6; three trials] at mid-treatment, −11.4 min [95% CI −31.8 to 9.0; three trials] at the end of treatment and −11.8 min [95% CI −62.9 to 39.2; one trial] at the 4-week follow-up. The corresponding standardised mean differences [SMDs] were −0.23 [95% CI −0.42 to −0.06], −0.10 [95% CI −0.29 to 0.08] and −0.09 [95% CI −0.48 to 0.30]. The heterogeneity was negligible in all analyses. The statistically significant result at mid-treatment was lost when excluding the apparently unblinded study in a sensitivity analysis: MD −13.8 min [95%CI −37.5 to 9.9] and SMD −0.13 [95%CI −0.35 to 0.09]. The registration of crying during treatment suggested more crying during acupuncture [odds ratio 7.7; 95% CI 2.7–20.6; one trial]. GRADE-Moderate quality evidence. Conclusions: Percutaneous needle acupuncture treatments should not be recommended for infantile colic on a general basis. Systematic review registration: PROSPERO 2015:CRD42015023253Key pointsThe role of acupuncture in the treatment of infantile colic is controversial. Available trials are small and present conflicting results.There were no clinically important differences between infants receiving acupuncture and no acupuncture control in this IPD meta-analysis of randomised controlled trials.The data indicate that acupuncture induces some treatment pain in many of the children.The study results indicate that percutaneous needle acupuncture should not be recommended for treatment of infantile colic on a general basis.
