Легочная гипертензия при диастолической дисфункции левого желудочка у больных с ишемической кардиомиопатией

На основании данных эхокардиографического исследования выявлена взаимосвязь между степенью легочной гипертензии и тяжестью диастолической дисфункции левого желудочка у больных с ишемической кардиомиопатией. Показано, что рестриктиное наполнение левого желудочка наблюдается в основном при выраженной легочной гипертензии.The findings of echocardiography were used to reveal interrelation between the degree of pulmonary hypertension and severity of diastolic dysfunction of the left ventricle in patients with ischemic cardiomyopathy. Restrictive filling of the left ventricle is shown to be observed in marked pulmonary hypertension

Antibodies to TRIM46 are associated with paraneoplastic neurological syndromes.

Paraneoplastic neurological syndromes (PNS) are often characterized by the presence of antineuronal antibodies in patient serum or cerebrospinal fluid. The detection of antineuronal antibodies has proven to be a useful tool in PNS diagnosis and the search for an underlying tumor. Here, we describe three patients with autoantibodies to several epitopes of the axon initial segment protein tripartite motif 46 (TRIM46). We show that anti-TRIM46 antibodies are easy to detect in routine immunohistochemistry screening and can be confirmed by western blotting and cell-based assay. Anti-TRIM46 antibodies can occur in patients with diverse neurological syndromes and are associated with small-cell lung carcinoma

Experience with combined heart-lung transplant at the University Medical Center Groningen

OBJECTIVE: Reporting the results of combined heart-lung transplantation in the University Medical Center Groningen (UMCG), the Netherlands.DESIGN: Retrospective study.METHOD: Data were retrieved of patients who underwent a combined heart-lung transplantation in the UMCG between December 1996 and December 2007. Demographic, clinical and other relevant characteristics were recorded, as well as post-transplantation morbidity and mortality.RESULTS: The study group consisted of 14 patients (3 men and 11 women) with a mean age of 41 years. Indications for heart-lung transplantation were: congenital heart disease complicated by pulmonary hypertension (6 patients), idiopathic pulmonary hypertension with severe right ventricle failure (4 patients), lung fibrosis with severe right ventricle failure (1 patient), cystic fibrosis with systolic left ventricle failure (1 patient), pulmonary hypertension after thoracic radiation and chemotherapy (1 patient) and re-transplantation after lung-transplant failure (1 patient). The mean waiting time prior to operation was approximately 1.5 years. 9 of the 14 patients (64%) underwent such a marked clinical deterioration during the waiting period that they were given a 'very high urgency status' for transplantation. Almost half of patients became dependent on supplementary intravenous inotropics during the waiting period. At the end of the study 6 of the 14 patients (43%) were alive, with a mean survival period of 58 months (range: 6-132). Infection was the cause of death in 4 of the 8 patients. Of the 8 deceased patients, 4 were underweight preoperatively (BMI &lt; 18.5 kg/m2) and were cachectic. This was the case in only 1 of the 6 surviving patients.CONCLUSION: A combined heart-lung transplantation is a rare operation in the Netherlands. The waiting time in this study was long and the post-transplantation mortality was high. Underweight (cachexia), a sign of a poor clinical condition, appears to be associated with mortality.</p

Predictive testing of minors for Huntington's disease: The UK and Netherlands experiences

A consistent feature of predictive testing guidelines for Huntington's disease (HD) is the recommendation not to undertake predictive tests on those < 18 years. Exceptions are made but the extent of, and reasons for, deviation from the guidelines are unknown. The UK Huntington's Prediction Consortium has collected data annually on predictive tests undertaken from the 23 UK genetic centers. DNA analysis for HD in the Netherlands is centralized in the Laboratory for Diagnostic Genome Analysis in Leiden. In the UK, 60 tests were performed on minors between 1994 and 2015 representing 0.63% of the total number of tests performed. In the Netherlands, 23 tests were performed on minors between 1997 and 2016. The majority of the tests were performed on those aged 16 and 17 years for both countries (23% and 57% for the UK, and 26% and 57% for the Netherlands). Data on the reasons for testing were identified for 36 UK and 22 Netherlands cases and included: close to the age of 18 years, pregnancy, currently in local authority care and likely to have less support available after 18 years, person never having the capacity to consent and other miscellaneous reasons. This study documents the extent of HD testing of minors in the UK and the Netherlands and suggests that, in general, the recommendation is being followed. We provide some empirical evidence as to reasons why clinicians have departed from the recommendation. We do not advise changing the recommendation but suggest that testing of minors continues to be monitored

The expanded clinical spectrum of anti-GABABR encephalitis and added value of KCTD16 autoantibodies

In this study we report the clinical features of 32 patients with gamma aminobutyric acid B receptor (GABABR) antibodies, identify additional autoantibodies in patients with anti-GABABR encephalitis that mark the presence of an underlying small cel

Search for single vector-like B quark production and decay via B → bH(b¯b) in pp collisions at √s = 13 TeV with the ATLAS detector

A search is presented for single production of a vector-like B quark decaying into a Standard Model b-quark and a Standard Model Higgs boson, which decays into a b¯b pair. The search is carried out in 139 fb−1 of √s = 13 TeV proton-proton collision data collected by the ATLAS detector at the LHC between 2015 and 2018. No significant deviation from the Standard Model background prediction is observed, and mass-dependent exclusion limits at the 95% confidence level are set on the resonance production cross-section in several theoretical scenarios determined by the couplings cW, cZ and cH between the B quark and the Standard Model W, Z and Higgs bosons, respectively. For a vector-like B occurring as an isospin singlet, the search excludes values of cW greater than 0.45 for a B resonance mass (mB) between 1.0 and 1.2 TeV. For 1.2 TeV < mB < 2.0 TeV, cW values larger than 0.50–0.65 are excluded. If the B occurs as part of a (B, Y) doublet, the smallest excluded cZ coupling values range between 0.3 and 0.5 across the investigated resonance mass range 1.0 TeV < mB < 2.0 TeV

Search for resonances decaying into photon pairs in 139 fb−1 of pp collisions at √s = 13 TeV with the ATLAS detector

Searches for new resonances in the diphoton final state, with spin 0 as predicted by theories with an extended Higgs sector and with spin 2 using a warped extra-dimension benchmark model, are presented using 139 fb−1 of √s = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. No significant deviation from the Standard Model is observed and upper limits are placed on the production cross-section times branching ratio to two photons as a function of the resonance mass
