Colonoscopic surveillance of first-degree relatives of colorectal cancer patients in a faecal occult blood screening programme

Background: In some Italian areas, colonoscopic surveillance of first-degree relatives (FDRs) of colorectal cancer (CRC) patients is provided as a part of local population-based faecal occult blood test (FOBT) screening programmes. The objective of the present study was to assess the feasibility and early results of this surveillance model. Methods: Data from district screening centres were used to evaluate the process of identification and selection of eligible FDRs (residence in the Emilia-Romagna Region, age 40–75 years, no recent colonoscopy) of screen-detected CRC patients and the detected prevalence of disease. The probability for an FDR to undergo colonoscopy and to be diagnosed with CRC and advanced adenoma was estimated using the Kaplan–Meier method. The sex- and age-standardised ratio of detected prevalence to that expected based on results from a colonoscopy screening study of the Italian general population was estimated. Results: Between 2005 and 2011, 9319 FDRs of 2437 screen-detected CRC patients (3.8 per patient) were identified and contacted. Their likelihood of being eligible for, and accepting, colonoscopy was 0.11 (95% confidence interval: 0.11–0.12). Among the 926 subjects undergoing colonoscopy, the prevalence of previous negative screening FOBT was 63%. Eleven CRCs (1.2%) and 100 advanced adenomas (10.8%) were detected. The standardised ratio of detected prevalence to that expected was 0.91 (95% confidence interval: 0.19–2.66) for CRC and 1.48 (1.04–2.05) for advanced adenoma. Conclusions: The procedure of selection of FDRs was extremely ineffective. Due to previous negative screening tests, the prevalence of disease was less than expected. A population-based FOBT screening programme is a highly unsuitable setting for the provision of surveillance to FDRs of CRC patients.     

What is the role of family in promoting faecal occult blood test screening? Exploring physician,average-risk individual,and family perceptions

Background: Although the number of Canadians being screened for colon cancer is rising, only 40% of Canadians aged 50 years or older reported they had engaged in faecal occult blood test (FOBT) screening as recommended. The notion of ‘partnerships’ that is inclusive of physicians, individuals at average-risk for colorectal cancer, and influential family members is receiving more attention in primary health care literature and policy on promoting health maintenance behaviours. To the best of our knowledge there are no studies that have taken a tripartite approach in describing perspectives of these three key stakeholders on the role of family in promoting adherence to FOBT. The aim of this study was to address the gap in understanding the perspectives of primary care physicians, individuals at average-risk for colorectal cancer, and family on family role in promoting adherence to FOBT screening. Method: We employed a qualitative design and conducted semi-structured interviews with 15 physicians, 27 patients at average-risk for colorectal cancer, and 19 family members or friends from urban and rural Manitoba, Canada between October 2008 and March 2010. Interviews were audio-recorded, transcribed verbatim, and analysed using content analysis and constant comparative techniques. Results: While physicians described a clear role for family in managing chronic disease or dealing with acute or serious illness, they identified barriers in working with family to promote FOBT screening: lack of time, privacy and confidentiality concerns, and family dynamics. Conversely, patients and family described instrumental, emotional, informational, and appraisal roles that family play in promoting FOBT outside medical encounters. Conclusion: Adherence to colorectal cancer screening is based on supportive ‘patient–physician’ dialogue that is separate from assistive ‘patient–family member’ relations. Further research is required to explore social support mechanisms involving family members outside medical encounters that hold promise in boosting self-efficacy, overcoming barriers, and gaining positive reinforcement for individuals at average-risk when making the decision to engage in FOBT.     

Screening and genetic counselling for relatives of patients with colorectal cancer in a family cancer clinic.

OBJECTIVE--To introduce and monitor a screening programme for first degree relatives of patients with colorectal cancer based on their calculated lifetime risk. DESIGN--Lifetime risks were calculated for first degree relatives of patients with colorectal cancer and used to offer screening based on estimated risk. SETTING--A family cancer clinic was set up as part of the North East Thames Regional Genetic Service for relatives of patients who had developed colorectal cancer before the age of 45 and members of families in which multiple cancer had occurred. PATIENTS--Self referrals as well as patients referred by general and hospital practitioners. INTERVENTION--Relatives with a lifetime risk of 1 in 10 or greater (high risk group) were offered screening five yearly by colonoscopy, and those whose risk was between 1 in 10 and 1 in 17 were offered yearly screening for faecal occult blood. Women with family histories compatible with Lynch type II cancer family syndrome were offered screening for breast and pelvic tumours. RESULTS--In four years 715 patients were seen. Acceptance of screening was 90% (644 patients). Of 151 patients screened for faecal occult blood, two were found to have polyps. This screening test was unsatisfactory for the high risk group, having a negative predictive value of 78% in 59 patients tested. Regular screening by colonoscopy was offered to 382 high risk patients; 62 patients with polyps and five with colonic cancer were found. One hundred and ten pedigrees were identified with the Lynch type II cancer family syndrome, and four of 35 women screened were found to have breast cancer. Of 14 relatives aged over 65 with a 1 in 2 risk of site specific colonic cancer or Lynch type II cancer family syndrome, seven were found to have polyps, one of whom had carcinoma in situ. CONCLUSIONS--Family history can be used to identify those at risk of colonic cancer and to target appropriate screening. Colonoscopy detected a high number of premalignant colonic polyps, but faecal occult blood testing was unsatisfactory for those at high risk of colorectal cancer.     

Impact of an educational video-based strategy on the behavior process associated with colorectal cancer screening: A randomized controlled study

Background: Low public awareness is an important barrier for colorectal cancer screening participation. Aim: To evaluate the impact of educational intervention on the health behavior process, patient knowledge and compliance with colorectal cancer screening in the average-risk population. Methods: 158 subjects (aged 50–79 years) were randomly assigned either to watch a non-medical video or a colorectal cancer educational video. Before and after watching the experimental or control videotape, participants completed a five-item questionnaire that assessed their knowledge about risk factors for colorectal cancer, age of risk, warning symptoms, 5-year prognosis, and incidence. Subjective risk perception for developing colorectal cancer, barriers or benefits of screening, and intention to be screened were also investigated. Finally, subjects received a faecal occult blood test kit and were requested to use and return it within 2 weeks. Results: Participants in the video-based intervention group showed significant improvement in knowledge of colorectal cancer scores (P < 0.001) and decreased barrier scores. The intervention group returned significantly more faecal occult blood tests than controls (69.6% vs. 54.4%, P = 0.035). The intervention had a positive effect on modifying attitudes and intention to take part in screening. Additionally, the intervention was a predictor of compliance (OR 2.0; 95% CI = 1.02–3.84, P = 0.044). Conclusion: Video-based intervention significantly reduced barriers to screening and improved participant awareness and compliance with colorectal cancer screening with faecal occult blood test.     

Family screening in patients with isolated bicuspid aortic valve: Restriction to those with aortic dilatation is not justified

AimTo determine the prevalence of undiagnosed bicuspid aortic valve (BAV) and isolated aortic dilatation in first-degree relatives (FDRs) of patients with isolated BAV and to explore the recurrence risk of BAV in different subgroups of probands with BAV. Recent American College of Cardiology (ACC)/American Heart Association (AHA) Guidelines recommend family screening in patients with associated aortopathy only.MethodsDuring follow-up visits, patients with isolated BAV received a printed invitation for their FDRs advising cardiac screening.ResultsFrom 2012–2019, 257 FDRs of 118 adult BAV patients were screened, among whom 63 (53%) index patients had undergone aortic valve surgery (AVS), including concomitant aortic replacement in 25 (21%). Of the non-operated index patients, 31 (26%) had aortic dilatation (> 40 mm). Mean age of the FDRs was 48 years (range 4–83) and 42% were male. The FDR group comprised 20 parents, 103 siblings and 134 offspring. Among these FDRs, 12 (4.7%) had a previously undiagnosed BAV and 23 (8.9%) had an isolated aortic dilatation. FDRs of the probands with previous AVS (n = 147) had a risk ratio for BAV of 2.25 (95% confidence interval (CI) 0.62–8.10). FDRs of the probands with BAV and repaired or unrepaired aortic dilatation (n = 127) had a risk ratio for BAV of 0.51 (95% CI 0.16–1.66).ConclusionScreening FDRs of patients with isolated BAV resulted in a reasonable yield of 14% new cases of BAV or isolated aortic dilatation. A trend towards an increased risk of BAV in FDRs was observed in the probands with previous AVS, whereas this risk seemed to be diminished in the probands with associated aortic dilatation. This latter finding does not support the restrictive ACC/AHA recommendation.     

Early detection of colon cancer: new tests on the horizon

This year, the American Cancer Society reported that the rate of decline in both the incidence and mortality of colorectal cancer has increased over the last two decades. This success is felt to be attributable to the early detection and treatment of colonic adenomas and early-stage colorectal cancers. However, the current recommended 'menu of options' for screening is limited by poor patient acceptance, low sensitivity, and both high cost and poor accessibility for application to a large general screening population (colonoscopy). Computerized tomography and magnetic resonance colonography offer an alternative method for the identification of polyps and early lesions in certain patients, but have cost, access, and acceptance limitations that are similar to those of colonoscopy; thus, they present similar barriers to their use in broad population screening. These limitations provide a strong rationale for the development of early colorectal cancer detection biomarkers that are simple to use and are cost effective. A successful biomarker or biomarker panel, coupled with the colonoscopic follow-up of only those patients with positive results, would reduce the burden and morbidity associated with the screening of colonoscopy. This would most likely result in enhanced adherence to colorectal screening, as well as a dramatic reduction in the incidence and mortality rates of colorectal cancer. In this paper, we review recent advances in the discovery of potential colorectal cancer biomarkers. Their applicability to clinical population screening will require large prospective validation.     

Coronary artery calcium findings in asymptomatic subjects with family history of premature coronary artery disease

ABSTRACT: BACKGROUND: To evaluate the frequency of positive coronary arteries calcium (CAC) scores in a unique population of asymptomatic first degree relatives (FDRs) of patients with angiographically confirmed early onset of coronary artery disease (CAD) and to assess their association with carotid ultrasound findings and other cardiovascular risk factors. Method and Results: We scanned, using 64-slice multi-detector computed tomography, 57 asymptomatic FDRs (47+9 years old; 44% male, 56% female), out of the 111 FDRs previously phenotyped for cardiovascular (CV) risk factors. The controls were 616 individuals (57+10 years old; 76% male, 24% female) with no family history of cardiovascular disease, chest pain or diabetes selected out of the 3500 subjects scanned between 2002 and 2007. FDRs had higher risk of abnormal CAC scores compared to controls; odds ratio (OR) for the 75th percentile was 1.96 (95%CI 1.04 - 3.67, p<0.05). CONCLUSION: The frequency of abnormal CAC scores is two-fold higher in asymptomatic FDRs than in controls. CAC scan provides additional information on CV risk assessment in asymptomatic FDRs, particularly for those in the intermediate risk category. Clinical Trial Registration: NCT00387595.     

Family Physicians' Barriers to Cancer Screening in Extremely Obese Patients

Extremely obese women are less likely than nonobese women to receive breast and cervical cancer screening examinations. Reasons for this disparity are unclear and may stem from patient and/or physician barriers. This sequential mixed‐methods study used individual in‐depth interviews of 15 family physicians followed by a mail survey of 255 family physicians (53% response rate) to understand the barriers they faced in performing cancer screening examinations in extremely obese women. Barriers fell into three main areas: (i) difficulty doing pelvic and breast exams; (ii) inadequate equipment; and (iii) challenges overcoming patient barriers and refusal. This led some physicians to avoid performing breast and pelvic examinations on extremely obese women. Having more knowledge about specific examination techniques was associated with less difficulty in palpating lumps on breast and pelvic examinations (P < 0.005). Physicians perceived that embarrassment, aversion to undressing, and avoidance of discussions related to their weight were the most frequent barriers extremely obese women had with getting physical examinations. Educating and/or motivating patients and addressing fears were strategies used most frequently when patients refused mammograms or Pap smears. Interventions focusing on physician barriers, such as educating them on specific examination techniques, obtaining adequate equipment and supplies, and providing resources to assist physicians in dealing with patient barriers and refusal, may be fruitful in increasing cancer screening rates in extremely obese patients. Future research studies testing the effectiveness of these strategies are needed to improve cancer outcomes in this high‐risk population.     

Factors determining dissemination of results and uptake of genetic testing in families with known BRCA1/2 mutations

BACKGROUND: Uptake of genetic testing remains low, even in families with known BRCA1 and BRCA2 (BRCA1/2) mutations, despite effective interventions to reduce risk. We report disclosure and uptake patterns by BRCA1/2-positive individuals to at-risk relatives, in the setting of no-cost genetic counseling and testing. METHODS: Relatives of BRCA1/2-positive individuals were offered cost-free and confidential genetic counseling and testing. If positive for a BRCA1/2 mutation, participants were eligible to complete a survey about their disclosure of mutation status and the subsequent uptake of genetic testing by at-risk family members. RESULTS: One hundred and fifteen of 142 eligible individuals responded to the survey (81%). Eighty-eight (77%) of those surveyed disclosed results to all at-risk relatives. Disclosure to first-degree relatives (FDRs) was higher than to second-degree relatives (SDRs) and third-degree relatives (TDR) (95% vs. 78%; p < 0.01). Disclosure rates to male versus female relatives were similar, but reported completion of genetic testing was higher among female versus male FDRs (73% vs. 49%; p < 0.01) and SDRs (68% vs. 43%; p < 0.01), and among members of maternal versus paternal lineages (63% vs. 0%; p < 0.01). Men were more likely than women to express general difficulty discussing positive BCRA1/2 results with at-risk family members (90% vs. 70%; p = 0.03), while women reported more emotional distress associated with disclosure than men (48% vs. 13%; p < 0.01). DISCUSSION: We report a very high rate of disclosure of genetic testing information to at-risk relatives. However, uptake of genetic testing among at-risk individuals was low despite cost-free testing services, particularly in men, SDRs, and members of paternal lineages. The complete lack of testing among paternally related at-risk individuals and the lower testing uptake among men signify a significant barrier to testing and a challenge for genetic counselors and physicians working with high-risk groups. Further research is necessary to ensure that family members understand their risk and the potential benefits of genetic counseling.     

High prevalence of spondyloarthritis and ankylosing spondylitis among familial Mediterranean fever patients and their first-degree relatives: further evidence for the connection

Introduction

Familial Mediterranean fever (FMF) is an auto-inflammatory disease characterized by recurrent attacks of fever and serositis. Limited data suggest that the prevalence of sacroiliitis is increased in patients with FMF. In our present study, we assessed the prevalence of spondyloarthritis (SpA), including ankylosing spondylitis (AS), among a cohort of FMF patients and their unaffected first-degree relatives (FDRs).

Methods

The current study cohort comprised a consecutive group of 201 unrelated patients with FMF and 319 FDRs (≥ 16 years old). These subjects were examined according to a standard protocol.

Results

A total of 157 FMF patients (78.1%) and 233 (73%) unaffected FDRs reported back pain. Fifteen FMF patients (7.5%) and nine unaffected FDRs fulfilled the modified New York (mNY) criteria for AS. One additional FDR with AS was identified after review of the medical records. None of the FMF patients with AS was HLA-B27 positive. The allele frequency of M694V among the FMF patients with radiographic sacroiliitis was significantly higher in comparison with those without sacroiliitis (OR 4.3). When compared with the general population, the risk ratios for SpA and AS among the FDRs of our FMF patients were 3.3 (95% CI; 2.0 to 5.5) and for AS 2.9 (95% CI; 1.3 to 6.4), respectively.

Conclusions

Our study suggests that a) factors other than HLA-B27 play a role in the association of FMF and SpA/AS; b) MEFV gene variations may be one of the geographic/region-specific potential pathogenetic links between these two disorders in the Turkish population.     

Factors associated with practice of colorectal cancer screening among primary care physicians in a Chinese population: A cross-sectional study

Objectives: Primary care physicians (PCPs) are influential in colorectal cancer (CRC) screening uptake in the community. This study aims to evaluate the factors associated with PCPs’ practice of CRC screening among asymptomatic patients in a Chinese population. Methods: A validated postal questionnaire was sent to all practicing PCPs who were members of a community-based network in Hong Kong. Three separate rounds of reminder letters were sent to non-respondents. Binary logistic regression analysis was used with ever-referral for CRC screening in the past 12 months as the outcome variable. Predictor variables include physicians’ gender, clinical experience, types of practice, and attitudes towards CRC screening. Results: Of 428 eligible physicians, 263 (61.4%) responded. A total of 187 physicians (71.1%) had referred patients for CRC screening in the past 1 year. Among all asymptomatic patients aged 50 years or older, physicians reported referring only 3.0% (1.0–10.0%) [median (interquartile range)] of patients. Colonoscopy (57.0%) and fecal occult blood testing (FOBT) (46.4%) were the most commonly recommended tests for these asymptomatic patients. Family history of CRC (58.6%) and patients’ concern about CRC (50.2%) were major reasons for referral. PCPs in private practice (adjusted odds ratio [aOR] 2.60, 95% C.I. 1.21–5.59) and those with positive attitude towards CRC screening (aOR 2.27, 95% C.I. 1.15–4.48) were more likely to recommend CRC screening. Conclusions: PCPs’ attitude towards CRC screening is a significant determinant of its practice. Future studies should identify and strengthen the influencers of PCPs’ attitude to enhance CRC screening rates.     

Hereditary site-specific colon cancer in a Canadian kindred.

A large kindred with colorectal cancer unaccompanied by polyposis coli and characterized by autosomal dominant inheritance has been identified in eastern Canada. Ten family members from three successive generations have presented 17 documented colorectal cancers. The clinical features of the kindred are characteristic of hereditary site-specific colon cancer (HSSCC) (Lynch syndrome I): absence of multiple polyposis, autosomal dominant inheritance, onset of colorectal cancer at an early age and a high incidence of synchronous and metachronous colorectal cancers. A unique feature of this family is the high incidence of sporadic adenomatous polyps in affected members and their relatives. Patients with HSSCC have been managed by means of segmental colectomy followed by annual colonoscopic surveillance. All five patients with localized (Dukes'' stage A or B) cancer at initial diagnosis were alive and free of disease after 2 to 12 years of follow-up, although three had required further colonic resection for metachronous carcinomas. Five young family members without cancer have had sporadic adenomatous polyps removed and are being followed with annual colonoscopy. It is not known whether polypectomy will alter the subsequent incidence of colon cancer. Subtotal colectomy is recommended for patients with HSSCC because of the high incidence of multiple lesions. An aggressive screening protocol, including colonoscopy, is recommended for all adult first- and second-degree relatives of patients with HSSCC. Identification of a biomarker, which is currently being sought in this kindred, would help identify those at greatest risk of development of cancer and allow earlier intervention.     

Knowledge,perception and practices of colorectal cancer screening in an ethnically diverse population

Background: Colorectal cancer (CRC) screening improves survival and its success depends on the participation of the at-risk population. Few studies have adequately assessed screening knowledge, perception and participation according to birthplace. This study assesses the knowledge and perception of CRC in an ethnically diverse population, and evaluates the association with screening participation and intention. Identification of specific predictors of screening may aid the development of interventions to improve overall CRC screening. Methods: An interview-based survey, conducted on subjects aged 30–70 years, assessed knowledge and perception towards CRC and screening tests. Primary endpoints were screening participation and intent. Statistical methods used were Chi-square, Mann–Whitney U and logistic regression. Results: A total of 543 subjects (43% males, 53% Australian-born (AB), 63% aged 50 years and above) were recruited. Compared with AB, non-Australian-born (NAB) respondents had poorer knowledge, and NAB background predicted for poorer knowledge independent of sex, education, media and familiarity with CRC patient. Compared with AB respondents aged 50 years and above, NAB respondents had lower screening participation (17.4% vs. 31.8%; P = 0.01), lesser intention (75.8% vs. 90.5%; P < 0.001), and had received fewer doctors’ screening recommendations (16.5% vs. 27.1%; P = 0.04). In multivariate analysis, doctors’ recommendation, media and improved perception independently predicted screening participation; knowledge and media exposure predicted intent. Conclusions: The knowledge of CRC and screening is significantly poorer in the immigrant population. Knowledge predicts for greater screening intent. Therefore, implementing language- and culture-specific educational programs involving medical practitioners and media are necessary to improve CRC screening participation rates.     

Colorectal cancer cases and relatives of cases indicate similar willingness to receive and disclose genetic information

Context: Recent developments in genetic testing allow us to detect individuals with inherited susceptibility to some cancers. Genetic testing to identify carriers of cancer-related mutations may help lower risk by encouraging preventive behaviors and surveillance. This study assessed willingness of colon cancer cases and relatives to receive genetic information that may indicate an increased risk for cancer, to whom they would disclose genetic information, and whether receiving genetic test results may influence future prevention behaviors among individuals enrolled in the Seattle Colorectal Cancer Family Registry. Methods: Incident invasive colorectal cancer cases were identified from the Puget Sound Surveillance Epidemiology and End Results (SEER) registry. In 2007, a sequential sample of cases and relatives (n = 147) were asked to respond to a questionnaire addressing study aims. The questionnaire was administered during a baseline or 5-year follow-up interview. Results: Patterns of response to each statement were similar between colorectal cancer cases and relatives. Both colorectal cases (95%) and relatives (95%) reported willingness to receive genetic information. Nearly all participants would tell their doctor the results of a genetic test (99% of cases; 98% of relatives), and all married participants would tell their spouses. Cases (96%) anticipated being slightly more likely than relatives (90%) to change their cancer screening behavior, but this difference was not statistically significant (p = 0.33). Conclusions: A high percentage of both colorectal cancer cases and relatives sampled from the Seattle Colorectal Cancer Family Registry are interested in identifying their genetic status, discussing their genetic status with their family and doctor, and adopting behavioral changes that may reduce cancer risk.     

Contextual determinants of participation in cervical cancer screening in France, 2010

BackgroundSome contextual factors associated with participation in cervical cancer screening are reported in the literature, but few studies have examined their combined effect. Our objective was to assess the role of contextual characteristics, separately and in combination, in participation in cervical cancer screening in France.MethodsMarginal Poisson regression models – taking into account the correlation between women in a given commune – were conducted using data from the Baromètre Santé 2010 survey. The characteristics of the commune of residence of the women studied were the potential spatial accessibility to general practitioners (GP) and gynecologists, the agglomeration category, and the socioeconomic level.ResultsThe analyses were performed in 3380 women, 88.2% of whom were up to date with their cervical cancer screening. Once the individual characteristics were taken into account, the screening participation rate was similar in all the communes, with the exception of those with poor access to a gynecologist and good access to a GP, where the rate was 6% lower (95%CI: 0.5–11%) than in the communes with good access to both GP and gynecologist. The same association with accessibility was observed in small agglomerations. Compared to women living in the more advantaged communes, the screening participation rate was 8% (2–12%) lower in those living in the more disadvantaged ones, except when accessibility to both types of physician was high.DiscussionWe observed an association between potential spatial accessibility to care in women’s residential communities and their cervical cancer screening practices, in particular in small agglomerations, rural communes, and more disadvantaged communes.     

Understanding potential barriers and enablers to a perioperative early phase cell therapy trial

Background aimsEarly-phase cell therapy clinical trials depend on patient and physician involvement, yet barriers can impede their participation.MethodsTo optimize engagement for a planned cell therapy trial to prevent perioperative cardiac complications, the authors conducted semi-structured interviews with at-risk patients and physicians who could potentially be involved in the study. The authors used the theoretical domains framework to systematically identify potential barriers and enablers.ResultsForty-one interviews were conducted to reach data saturation, and four overall potential barriers to participation (themes) were identified. Theme 1 emphasizes that patients and physicians need accessible information to better understand the benefits and risks of the novel therapy and trial procedures and to address misconceptions. Theme 2 underscores the need for clarity on whether the trial's primary purpose is safety or efficacy, as this may influence patient and physician decisions. Theme 3 recognizes the resource and logistic realities for patients (e.g., convenient follow-up appointments) and physicians (e.g., personnel to assist in trial procedures, competing priorities). Theme 4 describes the importance of social influences (e.g., physicians and family, peers/colleagues) that may affect decisions to participate and the importance of patient preferences (e.g., availability of physicians to discuss the trial, including caregivers in discussions).ConclusionsProspectively addressing these issues may help optimize feasibility prior to conducting an expensive, resource-intensive trial.     

Bioethics for clinicians: 14. Ethics and genetics in medicine

Information about a patient''s inherited risk of disease has important ethical and legal implications in clinical practice. Because genetic information is by nature highly personal yet familial, issues of confidentiality arise. Counselling and informed consent before testing are important in view of the social and psychological risks that accompany testing, the complexity of information surrounding testing, and the fact that effective interventions are often not available. Follow-up counselling is also important to help patients integrate test results into their lives and the lives of their relatives. Genetic counselling should be provided by practitioners who have up-to-date knowledge of the genetics of and the tests available for specific diseases, are aware of the social and psychological risks associated with testing, and are able to provide appropriate clinical follow-up. Some physicians may elect to refer patients for genetic counselling and testing. However, it is inevitable that all physicians will be involved in long-term follow-up both by monitoring for disease and by supporting the integration of genetic information into patients'' lives.     

Audit of terminal care in a general practice.

OBJECTIVE--To determine satisfaction of relatives and general practitioners with care of patients during terminal illness and make recommendations on improving terminal care in general practice. DESIGN--Interviews with available relatives of patients who had had terminal illnesses and died in 1987, supplemented by questionnaires; questionnaire survey of general practitioners after review of case notes of all their patients who had died of terminal illnesses in 1987. SETTING--One urban general practice. SUBJECTS--34 Relatives of patients with terminal illnesses who died in 1987; five general practitioners from one practice. RESULTS--In six cases relatives were dissatisfied, mainly because of lack of communication; in eight cases doctors were dissatisfied because of communication, poor symptom control, and inadequate care. IMPLICATIONS--There is a need for improved communication between relatives and the health professionals involved in terminal care as well as better advice on services and benefits available to both patients and relatives. Bereavement counselling should be better organised.     

The Association Between First-Degree Family History of Diabetes and Metabolic Syndrome

Objective: Because they share genetic and environmental factors with patients with diabetes, the first-degree relatives (FDRs) of patients with diabetes exhibit early signs of metabolic abnormalities. The present study aimed to investigate the correlation between family history of diabetes in FDRs and metabolic syndrome (MS), as well as changes in related risk factors.Methods: The present study population was a part of the baseline survey from the REACTION study. FDRs were defined as individuals having one or more FDRs with diabetes. MS and its components were defined according to the 2007 Joint Committee for Developing Chinese Guidelines.Results: A total of 2,692 individuals with an average age of 57.24 ± 8.35 years were enrolled in the present study. The prevalence of MS in FDRs (36.44%) was significantly higher than that in non-FDRs (25.28%; P<.001). FDRs accounted for 13.37%, 14.32%, 16.67%, 22.47%, 23.53%, and 25.58% of subjects with 0 to 5 MS components, showing an increasing trend (P for trend <.001). After adjusting for gender and age, partial correlation analyses showed significant associations of first-degree family history of diabetes with MS-related indexes (all P<.05). After adjusting for gender, age, lifestyle habits, and total metabolic traits, the first-degree family history of diabetes remained an independent factor that was positively associated with MS (odds ratio, 1.765; P<.001).Conclusion: A first-degree family history of diabetes predisposes individuals to developing MS and stands out as an independent risk factor for MS even without considering the subsequent effects of hyperglycemia.Abbreviations: BMI = body mass index; DBP = diastolic blood pressure; FDR = first-degree relative; FPG = fasting plasma glucose; HbA1c = glycated hemoglobin A1c; HDL-c = high-density-lipoprotein cholesterol; LDL-c = low-density-lipoprotein cholesterol; MAP = mean arterial pressure; MS = metabolic syndrome; OR = odds ratio; SBP = systolic blood pressure; TC = total cholesterol; TG = triglyceride; WC = waist circumference; WHR = waist-to-hip ratio; 2hPG = 2-hour plasma glucose
