Major Cardiac Events in Patients and Relatives With Hereditary Hypertrophic Cardiomyopathy

BackgroundLittle evidence is available on the disease expression in relatives of index patients with hypertrophic cardiomyopathy (HCM). This information has important implications for family screening programs, genetic counseling, and management of affected families.ObjectivesThe purpose of this study was to investigate the disease expression and penetrance in relatives of index patients carrying pathogenic/likely pathogenic (P/LP) variants in recognized HCM genes.MethodsA total of 453 consecutive and unrelated HCM index patients underwent clinical and genetic investigations. A total of 903 relatives of genotype-positive index patients were invited for clinical investigations and genetic testing. Penetrance, disease expression, and incidence rates of major adverse cardiac events (MACEs) were investigated in individuals carrying P/LP variants.ResultsForty percent (183/453) of index patients carried a P/LP variant. Eighty-four percent (757/903) of all relatives of index patients with P/LP variants were available for the investigation, of whom 54% (407/757) carried a P/LP variant. The penetrance of HCM among relatives was 39% (160/407). Relatives with HCM and index patients were diagnosed at a similar age (43 ± 18 years vs 46 ± 15 years; P = 0.11). There were no differences in clinical characteristics or incidence rates of MACE during 8 years of follow-up.ConclusionsThe disease expression of HCM among index patients and affected relatives carrying P/LP variants in recognized disease genes was similar, with an equal risk of experiencing MACE. These findings provide evidence to support family screening and follow-up of genotype-positive HCM families to improve management and diminish the number of adverse disease complications among relatives

Impact of HPV-associated p16-expression on radiotherapy outcome in advanced oropharynx and non-oropharynx cancer

AbstractBackground and purposeHPV is found in head and neck cancer from all sites with a higher prevalence in oropharynx cancer (OPC) compared to non-OPC. HPV/p16-status has a significant impact on radiotherapy (RT) outcome in advanced OPC, but less is known about the influence in non-OPC. We analyzed HPV-associated p16-expression in a cohort of patients with stage III–IV pharynx and larynx cancer treated with primary, curatively intended (chemo-)RT, aiming to test the hypothesis that the impact of HPV/p16 also extends to tumors of non-oropharyngeal origin.Material and methods1294 patients enrolled in previously conducted DAHANCA-trials between 1992 and 2012 were identified. Tumors were evaluated by p16-immunohistochemistry and classified as positive in case of staining in >70% of tumors cells.ResultsThirty-eight percent (490/1294) of the tumors were p16-positive with a significantly higher frequency in OPC (425/815) than in non-OPC (65/479), p<.0001. In OPC p16-positivity significantly improved loco-regional control (LRC) (adjusted HR [95% CI]: 0.43 [0.32–0.57]), event-free survival (EFS) (HR 0.44 [0.35–0.56]), and overall survival (OS) (HR: 0.38 [0.29–0.49]), respectively, compared with p16-negativity. In non-OPC no prognostic impact of p16-status was found for either endpoint: LRC (HR: 1.13 [0.75–1.70]), EFS (HR: 1.06 [0.76–1.47]), and OS (HR: 0.82 [0.59–1.16]).ConclusionsThe independent influence of HPV-associated p16-expression in advanced OPC treated with primary RT was confirmed. However, RT-outcome in the group of non-OPC did not differ by tumor p16-status, indicating that the prognostic impact may be restricted to OPC only

Nutritional care of medical inpatients: a health technology assessment

BACKGROUND: The inspiration for the present assessment of the nutritional care of medical patients is puzzlement about the divide that exists between the theoretical knowledge about the importance of the diet for ill persons, and the common failure to incorporate nutritional aspects in the treatment and care of the patients. The purpose is to clarify existing problems in the nutritional care of Danish medical inpatients, to elucidate how the nutritional care for these inpatients can be improved, and to analyse the costs of this improvement. METHODS: Qualitative and quantitative methods are deployed to outline how nutritional care of medical inpatients is performed at three Danish hospitals. The practices observed are compared with official recommendations for nutritional care of inpatients. Factors extraneous and counterproductive to optimal nutritional care are identified from the perspectives of patients and professional staff. A review of the literature illustrates the potential for optimal nutritional care. A health economic analysis is performed to elucidate the savings potential of improved nutritional care. RESULTS: The prospects for improvements in nutritional care are ameliorated if hospital management clearly identifies nutritional care as a priority area, and enjoys access to management tools for quality assurance. The prospects are also improved if a committed professional at the ward has the necessary time resources to perform nutritional care in practice, and if the care staff can requisition patient meals rich in nutrients 24 hours a day. At the kitchen production level prospects benefit from a facilitator contact between care and kitchen staff, and if the kitchen staff controls the whole food path from the kitchen to the patient. At the patient level, prospects are improved if patients receive information about the choice of food and drink, and have a better nutrition dialogue with the care staff. Better nutritional care of medical patients in Denmark is estimated to hold a cost savings potential reaching approximately USD 22 million. CONCLUSION: Every hospital and every bed ward has its strengths and weaknesses, but none of the participating bed wards fully satisfy nutritional care success criteria. All organisational levels have a significant potential for improvements of nutritional care of medical inpatients

Randomised comparison of provisional side branch stenting versus a two-stent strategy for treatment of true coronary bifurcation lesions involving a large side branch:the Nordic-Baltic Bifurcation Study IV

Background - It is still uncertain whether coronary bifurcations with lesions involving a large side branch (SB) should be treated by stenting the main vessel and provisional stenting of the SB (simple) or by routine two-stent techniques (complex). We aimed to compare clinical outcome after treatment of lesions in large bifurcations by simple or complex stent implantation. Methods - The study was a randomised, superiority trial. Enrolment required a SB≥2.75 mm, ≥50% diameter stenosis in both vessels, and allowed SB lesion length up to 15 mm. The primary endpoint was a composite of cardiac death, non-procedural myocardial infarction and target lesion revascularisation at 6 months. Two-year clinical follow-up was included in this primary reporting due to lower than expected event rates. Results - A total of 450 patients were assigned to simple stenting (n=221) or complex stenting (n=229) in 14 Nordic and Baltic centres. Two-year follow-up was available in 218 (98.6%) and 228 (99.5%) patients, respectively. The primary endpoint of major adverse cardiac events (MACE) at 6 months was 5.5% vs 2.2% (risk differences 3.2%, 95% CI −0.2 to 6.8, p=0.07) and at 2 years 12.9% vs 8.4% (HR 0.63, 95% CI 0.35 to 1.13, p=0.12) after simple versus complex treatment. In the subgroup treated by newer generation drug-eluting stents, MACE was 12.0% vs 5.6% (HR 0.45, 95% CI 0.17 to 1.17, p=0.10) after simple versus complex treatment. Conclusion - In the treatment of bifurcation lesions involving a large SB with ostial stenosis, routine two-stent techniques did not improve outcome significantly compared with treatment by the simpler main vessel stenting technique after 2 years
