Hereditary cancer registries improve the care of patients with a genetic predisposition to cancer: contributions from the Dutch Lynch syndrome registry

The Dutch Hereditary Cancer Registry was established in 1985 with the support of the Ministry of Health (VWS). The aims of the registry are: (1) to promote the identification of families with hereditary cancer, (2) to encourage the participation in surveillance programs of individuals at high risk, (3) to ensure the continuity of lifelong surveillance examinations, and (4) to promote research, in particular the improvement of surveillance protocols. During its early days the registry provided assistance with family investigations and the collection of medical data, and recommended surveillance when a family fulfilled specific diagnostic criteria. Since 2000 the registry has focused on family follow-up, and ensuring the quality of surveillance programs and appropriate clinical management. Since its founding, the registry has identified over 10,000 high-risk individuals with a diverse array of hereditary cancer syndromes. All were encouraged to participate in prevention programmes. The registry has published a number of studies that evaluated the outcome of surveillance protocols for colorectal cancer (CRC) in Lynch syndrome, as well as in familial colorectal cancer. In 2006, evaluation of the effect of registration and colonoscopic surveillance on the mortality rate associated with colorectal cancer (CRC) showed that the policy led to a substantial decrease in the mortality rate associated with CRC. Following discovery of MMR gene defects, the first predictive model that could select families for genetic testing was published by the Leiden group. In addition, over the years the registry has produced many cancer risk studies that have helped to develop appropriate surveillance protocols. Hereditary cancer registries in general, and the Lynch syndrome registry in particular, play an important role in improving the clinical management of affected families.Hereditary cancer genetic

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Patient and procedure-related risk factors for adverse events after infrainguinal bypass

Background: Current medical practice urges individual health care facilities and medical professionals to obtain and provide detailed insight in quality of care with the possibility of comparing data between institutions. Adverse event (AE) analysis serves as a mainstay in quality assessment in vascular surgery, but the comparison of A-E data between facilities can be complex. The aim of the present study was to assess independent risk factors for AE occurrence: patient, disease and operation characteristics besides general differences between health care facilities. Methods: All AEs after infrainguinal bypass graft procedures (BGPs) in three health care facilities in the Netherlands were evaluated. AEs were defined identically in the facilities. Results: Of 601 BGPs performed, 662 AEs were registered. Independent predictors of AEs were female gender (odds ratio [OR], 2.13; 95% confidence interval [CI], 1.39-3.26; P < .01), age 2:60 years (OR, 0.57; 95% CI, 0.34-0.95; P = .03), American Society of Anesthesiologists classification 3-4 (OR, 1.79; 95%, CI, 1.01-3.17; P = .05), comorbidities of ;pulmonary disease(OB, 2.99;95% CI, 1.67-5.34; P < .01)and diabetes mellitus (OR, 2.49;95% CI, 1.58-3.94; P < .01), distal anastomosis level at below knee femoropopliteal BGP (OF, 2.01; 95% CI, 1.26-3.22; P < .01), femorotibial BGP (OR, 2.40; 95% CI, 1.37-4.19; P < .01), and popliteopedal BGP (OF, 92.39; 95% CI, 11.13-766.98; P < .01). One health care facility had significantly fewer AEs than the other two (OR, 0.21; 95% CI, 0.13-0.35; P < .01). Conclusion: Age, gender, comorbidity, and type of surgery are all independent predictors of AE occurrence in vascular surgery. After adjustment for differences in these factors, one health care facility still had lower AE occurrence, which needs to be examined further.

A virtual asthma clinic for children: fewer routine outpatient visits, same asthma control

Contains fulltext : 177833.pdf (publisher's version ) (Closed access)eHealth is an appealing medium to improve healthcare and its value (in addition to standard care) has been assessed in previous studies. We aimed to assess whether an eHealth intervention could improve asthma control while reducing 50% of routine outpatient visits.In a multicentre, randomised controlled trial with a 16-month follow-up, asthmatic children (6-16 years) treated in eight Dutch hospitals were randomised to usual care (4-monthly outpatient visits) and online care using a virtual asthma clinic (VAC) (8-monthly outpatient visits with monthly web-based monitoring). Outcome measures were the number of symptom-free days in the last 4 weeks of the study, asthma control, forced expiratory volume in 1 s, exhaled nitric oxide fraction, asthma exacerbations, unscheduled outpatient visits, hospital admissions, daily dose of inhaled corticosteroids and courses of systemic corticosteroids.We included 210 children. After follow-up, symptom-free days differed statistically between the usual care and VAC groups (difference of 1.23 days, 95% CI 0.42-2.04; p=0.003) in favour of the VAC. In terms of asthma control, the Childhood Asthma Control Test improved more in the VAC group (difference of 1.17 points, 95% CI 0.09-2.25; p=0.03). No differences were found for other outcome measures.Routine outpatient visits can partly be replaced by monitoring asthmatic children via eHealth
