Non-Alcoholic Fatty Liver Disease (NAFLD) is a common condition affecting around 10-25% of the general adult population, 15% of children, and even > 50% of individuals who have type 2 diabetes mellitus. It is a major cause of liver-related morbidity, and cardiovascular (CV) mortality is a common cause of death. In addition to being the initial step of irreversible alterations of the liver parenchyma causing cirrhosis, about 1/6 of those who develop NASH are at risk also developing CV disease (CVD). More recently the acronym MAFLD (Metabolic Associated Fatty Liver Disease) has been preferred by many European and US specialists, providing a clearer message on the metabolic etiology of the disease. The suggestions for the management of NAFLD are like those recommended by guidelines for CVD prevention. In this context, the general approach is to prescribe physical activity and dietary changes the effect weight loss. Lifestyle change in the NAFLD patient has been supplemented in some by the use of nutraceuticals, but the evidence based for these remains uncertain. The aim of this Position Paper was to summarize the clinical evidence relating to the effect of nutraceuticals on NAFLD-related parameters. Our reading of the data is that whilst many nutraceuticals have been studied in relation to NAFLD, none have sufficient evidence to recommend their routine use; robust trials are required to appropriately address efficacy and safety.

Atherosclerotic cardiovascular disease (ASCVD) and consequent acute coronary syndromes (ACS) are substantial contributors to morbidity and mortality across Europe. Fortunately, as much as two thirds of this disease's burden is modifiable, in particular by lipid-lowering therapy (LLT). Current guidelines are based on the sound premise that, with respect to low-density lipoprotein cholesterol (LDL-C), "lower is better for longer", and recent data have strongly emphasised the need for also "the earlier the better". In addition to statins, which have been available for several decades, ezetimibe, bempedoic acid (also as fixed dose combinations), and modulators of proprotein convertase subtilisin/kexin type 9 (PCSK9 inhibitors and inclisiran) are additionally very effective approaches to LLT, especially for those at very high and extremely high cardiovascular risk. In real life, however, clinical practice goals are still not met in a substantial proportion of patients (even in 70%). However, with the options we have available, we should render lipid disorders a rare disease. In April 2021, the International Lipid Expert Panel (ILEP) published its first position paper on the optimal use of LLT in post-ACS patients, which complemented the existing guidelines on the management of lipids in patients following ACS, which defined a group of "extremely high-risk" individuals and outlined scenarios where upfront combination therapy should be considered to improve access and adherence to LLT and, consequently, the therapy's effectiveness. These updated recommendations build on the previous work, considering developments in the evidential underpinning of combination LLT, ongoing education on the role of lipid disorder therapy, and changes in the availability of lipid-lowering drugs. Our aim is to provide a guide to address this unmet clinical need, to provide clear practical advice, whilst acknowledging the need for patient-centred care, and accounting for often large differences in the availability of LLTs between countries.

Dědičná nádorová onemocnění tvoří malou, ale klinicky významnou část onkologických onemocnění, v České republice se jedná ročně o několik tisíc osob. Identifikace kauzální mutace v nádorových predispozičních genech má u těchto nemocných zásadní prognostický a v některých případech i prediktivní význam. Mimo to je podmínkou cílené preventivní péče o asymptomatické nosiče mutací v rodinách se zvýšeným rizikem vzniku nádorového onemocnění. Do současné doby bylo charakterizováno více než 150 nádorových predispozičních genů. Mutace většiny z nich se vyskytují vzácně, s výraznou populační specifičností a jejich klinická interpretace je často obtížná. Diagnostiku raritních variant technicky zjednodušují postupy využívající sekvenování nové generace, které umožňují vyšetření rozsáhlých sad genů. Za účelem racionalizace diagnostiky hereditárních nádorových syndromů v České republice jsme navrhli sekvenační panel „CZECANCA“, který cílí na vyšetření 219 genů asociovaných s dědičnými nádorovými onemocněními. Panel obsahuje přes 50 klinicky významných genů vysokého a středního rizika, zbývající geny tvoří málo prozkoumané a kandidátní predispoziční geny, jejichž vrozené mutace mají nejasnou klinickou interpretaci. Společně s návrhem panelu byl optimalizován postup vlastního sekvenování a bioinformatického zpracování sekvenačních dat pro tvorbu jednotné databáze genotypů analyzovaných vzorků. Cílem projektu je nabídnout použití sekvenačního panelu včetně optimalizovaného postupu sekvenování nové generace diagnostickým laboratořím v České republice a zajistit sdílení genotypů a klinických údajů o vyšetřovaných pacientech ve společné databázi za účelem zlepšení možnosti klinické interpretace vzácných mutací u vysoce rizikových osob.

Individuals with hereditary cancer syndromes form a minor but clinically important subgroup of oncology patients, comprising several thousand cases in the Czech Republic annually. In these patients, the identification of pathogenic mutations in cancer susceptibility genes has an important predictive and, in some cases, prognostic value. It also enables rational preventive strategies in asymptomatic carriers from affected families. More than 150 cancer susceptibility genes have been described so far; however, mutations in most of them are very rare, occurring with substantial population variability, and hence their clinical interpretation is very complicated. Diagnostics of mutations in cancer susceptibility genes have benefited from the broad availability of next-generation sequencing analyses using targeted gene panels. In order to rationalize the diagnostics of hereditary cancer syndromes in the Czech Republic, we have prepared the sequence capture panel “CZECANCA”, targeting 219 cancer susceptibility genes. Besides more than 50 clinically important high- and moderate-penetrance susceptibility genes, the panel also targets less common candidate genes with uncertain clinical relevance. Alongside the panel design, we have optimized the analytical and bioinformatics pipeline, which will facilitate establishing a collective nationwide database of genotypes and clinical data from the analyzed individuals. The key objective of this project is to provide diagnostic laboratories in the Czech Republic with a reliable procedure and collective database improving the clinical utility of next-generation sequencing analyses in high-risk patients, which would help improve the interpretation of rare or population-specific variants in cancer susceptibility genes.

Mutace HER2 jsou sice vzácné, ale klinicky velmi relevantní, zejména u nekuřáků a mladších pacientů s nemalobuněčným karcinomem plic (non-small cell lung cancer, NSCLC), a proto je třeba zajistit časnou identifikaci mutací HER2 (podle standardizovaných panelů sekvenování nové generace). Trastuzumab deruxtekan je účinná a bezpečná terapie pro HER2 mutovaný NSCLC - s robustními daty z registrační studie, a i přes absenci úhrady je vhodné jej testovat a u indikovaných pacientů usilovat o podání, včetně žádosti o výjimku, tak jak ji dokládáme v naší kazuistice. Toxicita této léčby je zvládnutelná a vcelku i předvídatelná, nicméně klíčová je edukace lékařského týmu i nemocného a nutnost pomýšlet na případnou včasnou detekci intersticiální plicní nemoci.

Although HER2 mutations are rare, they are clinically highly relevant, particularly in younger patients and non-smokers with non-smaii cell lung cancer (NSCLC). Early identification of HER2 mutations using standardized next generation sequencing panels is therefore essential. Trastuzumab deruxtecan is an effective and safe therapy for HER2-mutated NSCLC, supported by robust data from registration studies. Even in the absence of reimbursement, testing for HER2 mutations and pursuing treatment in eligible patients, including requests for compassionate use or exceptions is recommended, as illustrated in our case report. The toxicity profile of this therapy is generally manageable and largely predictable; however, thorough education of both the medical team and the patient is crucial, and vigilance for early detection of interstitial lung disease is warranted.

Accurate and consistent variant classification is imperative for incorporation of rapidly developing sequencing technologies into genomic medicine for improved patient care. An essential requirement for achieving standardized and reliable variant interpretation is data sharing, facilitated by a centralized open-source database. Familial hypercholesterolemia (FH) is an exemplar of the utility of such a resource: it has a high incidence, a favorable prognosis with early intervention and treatment, and cascade screening can be offered to families if a causative variant is identified. ClinVar, an NCBI-funded resource, has become the primary repository for clinically relevant variants in Mendelian disease, including FH. Here, we present the concerted efforts made by the Clinical Genome Resource, through the FH Variant Curation Expert Panel and global FH community, to increase submission of FH-associated variants into ClinVar. Variant-level data was categorized by submitter, variant characteristics, classification method, and available supporting data. To further reform interpretation of FH-associated variants, areas for improvement in variant submissions were identified; these include a need for more detailed submissions and submission of supporting variant-level data, both retrospectively and prospectively. Collaborating to provide thorough, reliable evidence-based variant interpretation will ultimately improve the care of FH patients.

PURPOSE: We set out to develop a publicly available tool that could accurately diagnose spinal muscular atrophy (SMA) in exome, genome, or panel sequencing data sets aligned to a GRCh37, GRCh38, or T2T reference genome. METHODS: The SMA Finder algorithm detects the most common genetic causes of SMA by evaluating reads that overlap the c.840 position of the SMN1 and SMN2 paralogs. It uses these reads to determine whether an individual most likely has 0 functional copies of SMN1. RESULTS: We developed SMA Finder and evaluated it on 16,626 exomes and 3911 genomes from the Broad Institute Center for Mendelian Genomics, 1157 exomes and 8762 panel samples from Tartu University Hospital, and 198,868 exomes and 198,868 genomes from the UK Biobank. SMA Finder's false-positive rate was below 1 in 200,000 samples, its positive predictive value was greater than 96%, and its true-positive rate was 29 out of 29. Most of these SMA diagnoses had initially been clinically misdiagnosed as limb-girdle muscular dystrophy. CONCLUSION: Our extensive evaluation of SMA Finder on exome, genome, and panel sequencing samples found it to have nearly 100% accuracy and demonstrated its ability to reduce diagnostic delays, particularly in individuals with milder subtypes of SMA. Given this accuracy, the common misdiagnoses identified here, the widespread availability of clinical confirmatory testing for SMA, and the existence of treatment options, we propose that it is time to add SMN1 to the American College of Medical Genetics list of genes with reportable secondary findings after genome and exome sequencing.

BACKGROUND: In the current European Association of Urology (EAU) non-muscle-invasive bladder cancer (NMIBC) guideline, two classification systems for grade are advocated: WHO1973 and WHO2004/2016. OBJECTIVE: To compare the prognostic value of these WHO systems. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data for 5145 primary Ta/T1 NMIBC patients from 17 centers were collected between 1990 and 2019. The median follow-up was 3.9 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Univariate and multivariable analyses of WHO1973 and WHO2004/2016 stratified by center were performed for time to recurrence, progression (primary endpoint), cystectomy, and duration of survival, taking into account age, concomitant carcinoma in situ, gender, multiplicity, tumor size, initial treatment, and tumor stage. Harrell's concordance (C-index) was used for prognostic accuracy of classification systems. RESULTS AND LIMITATIONS: The median age was 68 yr; 3292 (64%) patients had Ta tumors. Neither classification system was prognostic for recurrence. For a four-tier combination of both WHO systems, progression at 5-yr follow-up was 1.4% in low-grade (LG)/G1, 3.8% in LG/G2, 7.7% in high grade (HG)/G2, and 18.8% in HG/G3 (log-rank, p < 0.001). In multivariable analyses with WHO1973 and WHO2004/2016 as independent variables, WHO1973 was a significant prognosticator of progression (p <  0.001), whereas WHO2004/2016 was not anymore (p =  0.067). C-indices for WHO1973, WHO2004, and the WHO systems combined for progression were 0.71, 0.67, and 0.73, respectively. Prognostic analyses for cystectomy and survival showed results similar to those for progression. CONCLUSIONS: In this large prognostic factor study, both classification systems were prognostic for progression but not for recurrence. For progression, the prognostic value of WHO1973 was higher than that of WHO 2004/2016. The four-tier combination (LG/G1, LG/G2, HG/G2, and HG/G3) of both WHO systems proved to be superior, as it divides G2 patients into two subgroups (LG and HG) with different prognoses. Hence, the current EAU-NMIBC guideline recommendation to use both WHO classification systems remains correct. PATIENT SUMMARY: At present, two classification systems are used in parallel to grade non-muscle-invasive bladder tumors. Our data on a large number of patients showed that the older classification system (WHO1973) performed better in terms of assessing progression than the more recent (WHO2004/2016) one. Nevertheless, we conclude that the current guideline recommendation for the use of both classification systems remains correct, since this has the advantage of dividing the large group of WHO1973 G2 patients into two subgroups (low and high grade) with different prognoses.
