Olaparib Addition to Maintenance Bevacizumab Therapy in Ovarian Carcinoma With BRCA-Like Genomic Aberrations.

Importance: Testing for homologous recombination deficiency is required for the optimal treatment of high-grade epithelial ovarian cancer. The search for accurate biomarkers is ongoing. Objective: To investigate whether progression-free survival (PFS) and overall survival (OS) of patients with high-grade epithelial ovarian cancer treated with maintenance olaparib or placebo differed between patients with a tumor BRCA-like genomic profile and patients without a tumor BRCA-like profile. Design, Setting, and Participants: This cohort study was a secondary analysis of the PAOLA-1 randomized clinical trial that compared olaparib plus bevacizumab with placebo plus bevacizumab as maintenance treatment in patients with advanced high-grade ovarian cancer after a good response to first-line platinum with taxane chemotherapy plus bevacizumab, irrespective of germline or tumor BRCA1/2 mutation status. All patients with available tumor DNA were included in the analysis. The current analysis tested for an interaction between BRCA-like status and olaparib treatment on survival outcomes. The original trial was conducted between July 2015 and September 2017; at the time of data extraction for analysis in March 2022, a median follow-up of 54.1 months (IQR, 28.5-62.2 months) and a total follow-up time of 21 711 months was available, with 336 PFS and 245 OS events. Exposures: Tumor homologous recombination deficiency was assessed using the BRCA-like copy number aberration profile classifier. Myriad MyChoice CDx was previously measured. The trial was randomized between the olaparib and bevacizumab and placebo plus bevacizumab groups. Main Outcomes and Measures: This secondary analysis assessed hazard ratios (HRs) of olaparib vs placebo among biomarker strata and tested for interaction between BRCA-like status and olaparib treatment on PFS and OS, using Cox proportional hazards regression. Results: A total of 469 patients (median age, 60 [range 26-80] years) were included in this study. The patient cohort consisted of women with International Federation of Gynaecology and Obstetrics stage III (76%) high-grade serous (95%) ovarian cancer who had no evaluable disease or complete remission at initial or interval debulking surgery (76%). Thirty-one percent of the tumor samples (n = 138) harbored a pathogenic BRCA mutation, and BRCA-like classification was performed for 442 patients. Patients with a BRCA-like tumor had a longer PFS after olaparib treatment than after placebo (36.4 vs 18.6 months; HR, 0.49; 95% CI, 0.37-0.65; P < .001). No association of olaparib with PFS was found in patients with a non-BRCA-like tumor (17.6 vs 16.6 months; HR, 1.02; 95% CI, 0.68-1.51; P = .93). The interaction was significant (P = .004), and HRs and P values (for interaction) were similar in the relevant subgroups, OS, and multivariable analyses. Conclusions and Relevance: In this secondary analysis of the PAOLA-1 randomized clinical trial, patients with a BRCA-like tumor, but not those with a non-BRCA-like tumor, had a significantly longer survival after olaparib plus bevacizumab treatment than placebo plus bevacizumab treatment. Thus, the BRCA1-like classifier could be used as a biomarker for olaparib plus bevacizumab as a maintenance treatment.

Prediction of Mortality and Heart Failure Hospitalization After Transcatheter Tricuspid Valve Interventions: Validation of TRISCORE.

BACKGROUND: Data on the prognostic role of the TRI-SCORE in patients undergoing transcatheter tricuspid valve intervention (TTVI) are limited. OBJECTIVES: The aim of this study was to evaluate the performance of the TRI-SCORE in predicting outcomes of patients undergoing TTVI. METHODS: TriValve (Transcatheter Tricuspid Valve Therapies) is a large multicenter multinational registry including patients undergoing TTVI. The TRI-SCORE is a risk model recently proposed to predict in-hospital mortality after tricuspid valve surgery. The TriValve population was stratified based on the TRI-SCORE tertiles. The outcomes of interest were all-cause death and all-cause death or heart failure hospitalization. Procedural complications and changes in NYHA functional class were also reported. RESULTS: Among the 634 patients included, 223 patients (35.2%) had a TRI-SCORE between 0 and 5, 221 (34.8%) had 6 or 7, and 190 (30%) had ≥8 points. Postprocedural blood transfusion, acute kidney injury, new atrial fibrillation, and in-hospital mortality were more frequent in the highest TRI-SCORE tertile. Postprocedure length of stay increased with a TRI-SCORE increase. A TRI-SCORE ≥8 was associated with an increased risk of 30-day all-cause mortality and all-cause mortality and the composite endpoint assessed at a median follow-up of 186 days (OR: 3.00; 95% CI: 1.38-6.55; HR: 2.17; 95% CI: 1.78-4.13; HR: 2.08, 95% CI: 1.57-2.74, respectively) even after adjustment for procedural success and EuroSCORE II or Society of Thoracic Surgeons Predicted Risk of Mortality. The NYHA functional class improved across all TRI-SCORE values. CONCLUSIONS: In the TriValve registry, the TRI-SCORE has a suboptimal performance in predicting clinical outcomes. However, a TRISCORE ≥8 is associated with an increased risk of clinical events and a lack of prognostic benefit after successful TTVI.

Metastatic Penile Squamous Cell Carcinoma: Unmasked by an Acute Myocardial Infarction and Terminal Heart Failure.

A young patient, recently treated for squamous cell penile carcinoma, presented with acute myocardial infarction and severe heart failure. Despite repeatedly ruling out metastatic disease on imaging, surgery for a mechanical assist device revealed unexpected squamous cell metastasis in the pericardium. Consequently, palliative care was initiated.

Transthyretin amyloid cardiomyopathy among patients with heart failure and preserved ejection fraction: the AMY score.

AIMS: Transthyretin 'wild-type' amyloid cardiomyopathy (ATTRwt-CM) is a differential diagnosis of heart failure with preserved ejection fraction (HFpEF). The clinical work-up for ATTRwt-CM is challenging. Considering a combination of clinical variables specific for ATTRwt-CM might aid in identifying patients at risk. METHODS AND RESULTS: Sixty patients (78 ± 6 years, 8% female) were diagnosed with ATTRwt-CM by endomyocardial biopsy. Preserved ejection fraction (LVEF >45%) was present in 41 of the patients. Those were 1:1 propensity score age- and sex-matched to a cohort of patients with HFpEF. ATTRwt-CM patients had less obesity (P = 0.01) and higher septal thickness (IVSd, P < 0.01) as well as more diastolic dysfunction (E/e', P < 0.01). On multivariable regression IVSd > 14 mm, E/e' > 14 and absence of obesity (P > 0.01 for all) were identified as predictors for ATTRwt-CM. A weighted point-based score was derived with IVSd > 14 mm = 1 point; absence of obesity = 2 points; and E/e' > 14 = 3 points. Area under the curve (AUC) for the summation score was 0.91 (0.84-0.97, P < 0.01) and a score of more than 3 points predicted ATTRwt-CM with good sensitivity (78%) and specificity (90%). The score was validated in an external cohort of 142 patients with ATTRwt-CM and 419 HFpEF patients showing sufficient accuracy (AUC 0.91, 0.88-0.94, P < 0.01). A value greater than 3 points demonstrated a high sensitivity (93%) and a negative predictive value of 97%. CONCLUSIONS: A score based on basic clinical and echocardiographic features helps to distinguish ATTRwt-CM from typical HFpEF. This could facilitate the diagnostic work-up for these patients and enable earlier disease screening on a large scale.

Neurological Disorders in Takotsubo Syndrome: Clinical Phenotypes and Outcomes.

BACKGROUND: Neurological disorders as a risk factor for Takotsubo syndrome (TTS) are not well characterized. The aim of the study was to evaluate TTS-associated neurological phenotypes and outcome. METHODS AND RESULTS: Patients with TTS enrolled in the international multicenter GEIST (German Italian Spanish Takotsubo) registry were analyzed. Prevalence, clinical characteristics, and short- and long-term outcomes of patients with TTS were recorded. A subgroup analysis of the 5 most represented neurological disorders was performed. In total, 400 (17%) of 2301 patients had neurological disorders. The most represented neurological conditions were previous cerebrovascular events (39%), followed by neurodegenerative disorders (30.7%), migraine (10%), epilepsy (9.5%), and brain tumors (5%). During hospitalization, patients with neurological disorders had longer in-hospital stay (8 [interquartile range, 5-12] versus 6 [interquartile range, 5-9] days; P<0.01) and more often experienced in-hospital complications (27% versus 16%; P=0.01) mainly driven by cardiogenic shock and in-hospital death (12% versus 7.6% and 6.5% versus 2.8%, respectively; both P<0.01). Survival analysis showed a higher mortality rate in neurological patients both at 60 days and long-term (8.8% versus 3.4% and 23.5% versus 10.1%, respectively; both P<0.01). Neurological disorder was an independent predictor of both the 60-day and long-term mortality rate (odds ratio, 1.78 [95% CI, 1.07-2.97]; P=0.02; hazard ratio, 1.72 [95% CI, 1.33-2.22]; both P<0.001). Patients with neurodegenerative disorders had the worst prognosis among the neurological disease subgroups, whereas patients with TTS with migraine had a favorable prognosis (long-term mortality rates, 29.2% and 9.7%, respectively). CONCLUSIONS: Neurological disorders identify a high-risk TTS subgroup for enhanced short- and long-term mortality rate. Careful recognition of neurological disorders and phenotype is therefore needed.

Amphetamine increases vascular permeability by modulating endothelial actin cytoskeleton and NO synthase via PAR-1 and VEGF-R.

Abuse of amphetamine-type stimulants is linked to cardiovascular adverse effects like arrhythmias, accelerated atherosclerosis, acute coronary syndromes and sudden cardiac death. Excessive catecholamine release following amphetamine use causes vasoconstriction and vasospasms, over time leading to hypertension, endothelial dysfunction or even cardiotoxicity. However, immediate vascular pathomechanisms related to amphetamine exposure, especially endothelial function, remain incompletely understood and were analyzed in this study. Pharmaco-pathological effects of acute d-amphetamine-sulfate (DAM) were investigated ex vivo using contraction-force measurements of rat carotid artery rings and in vitro using label-free, real-time electrochemical impedance spectroscopy (EIS) on endothelial and smooth muscle cells. Specific receptor and target blocking was used to identify molecular targets and to characterize intracellular signaling. DAM induced vasodilation represented by 29.3±2.5% decrease in vascular tone (p<0.001) involving vascular endothelial growth factor receptor (VEGF-R) and protease activated receptor 1 (PAR-1). EIS revealed that DAM induces endothelial barrier disruption (-75.9±1.1% of initial cellular impedance, p<0.001) also involving VEGF-R and PAR-1. Further, in response to DAM, Rho-associated protein kinase (ROCK) mediated reversible contraction of actin cytoskeleton resulting in endothelial barrier disruption. Dephosphorylation of Serine1177 (-50.8±3.7%, p<0.001) and Threonine495 (-44.8±6.5%, p=0.0103) of the endothelial NO synthase (eNOS) were also observed. Blocking of VEGF-R and PAR-1 restored baseline eNOS Threonine495 phosphorylation. DAM induced vasodilation, enhanced vascular permeability and actin cytoskeleton contraction and induced eNOS hypophosphorylation involving VEGF-R, PAR-1 and ROCK. These results may contribute to a better understanding of severe adverse cardiovascular effects in amphetamine abuse.

Impact of anaemia and iron deficiency on outcomes in cardiogenic shock complicating acute myocardial infarction.

AIMS: Anaemia and iron deficiency (ID) are common comorbidities in cardiovascular patients and are associated with a poor clinical status, as well as a worse outcome in patients with heart failure and acute myocardial infarction (AMI). Nevertheless, data concerning the impact of anaemia and ID on clinical outcomes in patients with cardiogenic shock (CS) are scarce. This study aimed to assess the impact of anaemia and ID on clinical outcomes in patients with CS complicating AMI. METHODS AND RESULTS: The presence of anaemia (haemoglobin <13 g/dl in men and <12 g/dl in women) or ID (ferritin <100 ng/ml or transferrin saturation <20%) was determined in patients with CS due to AMI from the CULPRIT-SHOCK trial. Blood samples were collected in the catheterization laboratory during initial percutaneous coronary intervention. Clinical outcomes were compared in four groups of patients having neither anaemia nor ID, against patients with anaemia with or without ID and patients with ID only. A total of 427 CS patients were included in this analysis. Anaemia without ID was diagnosed in 93 (21.7%), anaemia with ID in 54 study participants (12.6%), ID without anaemia in 72 patients (16.8%), whereas in 208 patients neither anaemia nor ID was present (48.9%). CS patients with anaemia without ID were older (73 ± 10 years, p = 0.001), had more frequently a history of arterial hypertension (72.8%, p = 0.01), diabetes mellitus (47.8%, p = 0.001), as well as chronic kidney disease (14.1%, p = 0.004) compared to CS patients in other groups. Anaemic CS patients without ID presence were at higher risk to develop a composite from all-cause death or renal replacement therapy at 30-day follow-up (odds ratio [OR] 3.83, 95% confidence interval [CI] 2.23-6.62, p < 0.001) than CS patients without anaemia/ID. The presence of ID in CS patients, with and without concomitant anaemia, did not increase the risk for the primary outcome (OR 1.17, 95% CI 0.64-2.13, p = 0.64; and OR 1.01, 95% CI 0.59-1.73, p = 0.54; respectively) within 30 days of follow-up. In time-to-event Kaplan-Meier analysis, anaemic CS patients without ID had a significantly higher hazard ratio (HR) for the primary outcome (HR 2.11, 95% CI 1.52-2.89, p < 0.001), as well as for death from any cause (HR 1.90, 95% CI 1.36-2.65, p < 0.001) and renal replacement therapy during 30-day follow-up (HR 2.99, 95% CI 1.69-5.31, p < 0.001). CONCLUSION: Concomitant anaemia without ID presence in patients with CS at hospital presentation is associated with higher risk for death from any cause or renal replacement therapy and the individual components of this composite endpoint within 30 days after hospitalization. ID has no relevant impact on clinical outcomes in patients with CS.

Infective Endocarditis After Transcatheter Versus Surgical Aortic Valve Replacement.

BACKGROUND: Scarce data are available comparing infective endocarditis (IE) following surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR). This study aimed to compare the clinical presentation, microbiological profile, management, and outcomes of IE after SAVR versus TAVR. METHODS: Data were collected from the "Infectious Endocarditis after TAVR International" (enrollment from 2005 to 2020) and the "International Collaboration on Endocarditis" (enrollment from 2000 to 2012) registries. Only patients with an IE affecting the aortic valve prosthesis were included. A 1:1 paired matching approach was used to compare patients with TAVR and SAVR. RESULTS: A total of 1688 patients were included. Of them, 602 (35.7%) had a surgical bioprosthesis (SB), 666 (39.5%) a mechanical prosthesis, 70 (4.2%) a homograft, and 350 (20.7%) a transcatheter heart valve. In the SAVR versus TAVR matched population, the rate of new moderate or severe aortic regurgitation was higher in the SB group (43.4% vs 13.5%; P < .001), and fewer vegetations were diagnosed in the SB group (62.5% vs 82%; P < .001). Patients with an SB had a higher rate of perivalvular extension (47.9% vs 27%; P < .001) and Staphylococcus aureus was less common in this group (13.4% vs 22%; P = .033). Despite a higher rate of surgery in patients with SB (44.4% vs 27.3%; P < .001), 1-year mortality was similar (SB: 46.5%; TAVR: 44.8%; log-rank P = .697). CONCLUSIONS: Clinical presentation, type of causative microorganism, and treatment differed between patients with an IE located on SB compared with TAVR. Despite these differences, both groups exhibited high and similar mortality at 1-year follow-up.

Infarct severity and outcomes in ST-elevation myocardial infarction patients without standard modifiable risk factors - A multicenter cardiac magnetic resonance study.

BACKGROUND: Standard modifiable cardiovascular risk factors (SMuRFs) are well-established players in the pathogenesis of ST-elevation myocardial infarction (STEMI). However, in a significant proportion of STEMI patients, no SMuRFs can be identified, and the outcomes of this subgroup are not well described. OBJECTIVES: To assess the infarct characteristics at myocardial-tissue level and subsequent clinical outcomes in SMuRF-less STEMIs. METHODS: This multicenter, individual patient-data analysis included 2012 STEMI patients enrolled in four cardiac magnetic resonance (CMR) imaging studies conducted in Austria, Germany, Scotland, and the Netherlands. Unstable patients at time of CMR (e.g. cardiogenic shock/after cardiac arrest) were excluded. SMuRF-less was defined as absence of hypertension, smoking, hypercholesterolemia, and diabetes mellitus. All patients underwent CMR 3(interquartile range [IQR]:2-4) days after infarction to assess left ventricular (LV) volumes and ejection fraction, infarct size and microvascular obstruction (MVO). Clinical endpoints were defined as major adverse cardiovascular events (MACE), including all-cause mortality, re-infarction and heart failure. RESULTS: No SMuRF was identified in 185 patients (9%). These SMuRF-less patients were older, more often male, had lower TIMI risk score and pre-interventional TIMI flow, and less frequently multivessel-disease. SMuRF-less patients did not show significant differences in CMR markers compared to patients with SMuRFs (all p > 0.10). During a median follow-up of 12 (IQR:12-27) months, 199 patients (10%) experienced a MACE. No significant difference in MACE rates was observed between SMuRF-less patients and patients with SMuRFs (8vs.10%, p = 0.39). CONCLUSIONS: In this large individual patient-data pooled analysis of low-risk STEMI patients, infarct characteristics and clinical outcomes were not different according to SMuRF status.

Impact of Access Site on Periprocedural Bleeding and Cerebral and Coronary Events in High-Bleeding-Risk Percutaneous Coronary Intervention: Findings from the RIVA-PCI Trial.

INTRODUCTION: The preference for using transradial access (TRA) over transfemoral access (TFA) in patients requiring percutaneous coronary intervention (PCI) is based on evidence suggesting that TRA is associated with less bleeding and fewer vascular complications, shorter hospital stays, improved quality of life, and a potential beneficial effect on mortality. We have limited study data comparing the two access routes in a patient population with atrial fibrillation (AF) undergoing PCI, who have a particular increased risk of bleeding, while AF itself is associated with an increased risk of thromboembolism. METHODS: Using data from the RIVA-PCI registry, which includes patients with AF undergoing PCI, we analyzed a high-bleeding-risk (HBR) cohort. These patients were predominantly on oral anticoagulants (OAC) for AF, and the PCI was performed via radial or femoral access. Endpoints examined were in-hospital bleeding (BARC 2-5), cerebral events (TIA, hemorrhagic or ischemic stroke) and coronary events (stent thrombosis and myocardial infarction). RESULTS: Out of 1636 patients, 854 (52.2%) underwent TFA, while 782 (47.8%) underwent the procedure via TRA, including nine patients with brachial artery puncture. The mean age was 75.5 years. Groups were similar in terms of age, sex distribution, AF type, cardiovascular history, risk factors, and comorbidities, except for a higher incidence of previous bypass surgeries, heart failure, hyperlipidemia, and chronic kidney disease (CKD) with a glomerular filtration rate (GFR) < 60 ml/min in the TFA group. No clinically relevant differences in antithrombotic therapy and combinations were present at the time of PCI. However, upon discharge, transradial PCI patients had a higher rate of triple therapy, while dual therapy was preferred after transfemoral procedures. Radial access was more frequently chosen for non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina pectoris (UAP) cases (NSTEMI 26.6% vs. 17.0%, p < 0.0001; UAP 21.5% vs. 14.5%, p < 0.001), while femoral access was more common for elective PCI (60.3% vs. 44.1%, p < 0.0001). No differences were observed for ST-segment elevation myocardial infarction (STEMI). Both groups had similar rates of cerebral events (TFA 0.2% vs. TRA 0.3%, p = 0.93), but the TFA group had a higher incidence of bleeding (BARC 2-5) (4.2% vs. 1.5%, p < 0.01), mainly driven by BARC 3 bleeding (1.5% vs. 0.4%, p < 0.05). No significant differences were found for stent thrombosis and myocardial infarction (TFA 0.2% vs. TRA 0.3%, p = 0.93; TFA 0.4% vs. TRA 0.1%, p = 0.36). CONCLUSIONS: In HBR patients with AF undergoing PCI for acute or chronic coronary syndrome, the use of TRA might be associated with a decrease in in-hospital bleeding, while not increasing the risk of embolic or ischemic events compared to femoral access. Further studies are required to confirm these preliminary findings.

Statin therapy and outcome in Takotsubo syndrome patients: Results from the multicenter international GEIST registry.

BACKGROUND AND AIMS: Several studies have shown that endothelial dysfunction plays a role in the pathogenesis of Takotsubo syndrome (TTS). Given the potential benefit of statin therapy on endothelial dysfunction, we hypothesized that such treatment could improve outcome. Aim of our study was to evaluate clinical characteristics and outcome of TTS patients treated with statin therapy. METHODS: Patients were enrolled in the international multicenter GEIST (GErman Italian Spanish Takotsubo) registry. Demographic data, clinical features and drug therapy at discharge were recorded. Primary study outcome was the occurrence of all-cause death at follow-up. RESULTS: Study population included 2429 consecutive TTS patients: 1293 (53.2%) discharged on statin and 1136 (46.8%) without statin. Patients with statin were older (age 72 ± 11 vs 69 ± 13 years, p < 0.001), with higher prevalence of hypertension (74.3% vs 60.3%, p < 0.001), diabetes (21.1% vs 14.7%, p < 0.001), dyslipidemia (56.1% vs 23.3%, p < 0.001), history of coronary artery disease (13.3% vs 6.3%, p < 0.001) and lower rates of in-hospital complications (14.7% vs 19.3%, p = 0.003). Survival analysis showed similar mortality rates between groups (log rank p = 0.803). At univariable analysis, statin therapy at discharge was not associated with lower mortality (HR: 0.97, 95% CI 0.74-1.26, p = 0.803). At multivariable analysis age (HR: 1.06 95% CI 1.04-1.08, p < 0.001), male sex (HR: 1.83, 95% CI 1.20-2.80, p = 0.005), diabetes (HR: 2.55, 95% CI 1.83-3.54 p < 0.001), malignancies (HR: 2.41, 95% CI 1.68-3.44, p < 0.001) and physical trigger (HR: 2.24, 95% CI 1.62-3.10, p < 0.001) were associated with increased mortality. CONCLUSIONS: Statin therapy after a TTS event was not associated with better prognosis at follow-up.

Health position paper and redox perspectives on reactive oxygen species as signals and targets of cardioprotection.

The present review summarizes the beneficial and detrimental roles of reactive oxygen species in myocardial ischemia/reperfusion injury and cardioprotection. In the first part, the continued need for cardioprotection beyond that by rapid reperfusion of acute myocardial infarction is emphasized. Then, pathomechanisms of myocardial ischemia/reperfusion to the myocardium and the coronary circulation and the different modes of cell death in myocardial infarction are characterized. Different mechanical and pharmacological interventions to protect the ischemic/reperfused myocardium in elective percutaneous coronary interventions and coronary artery bypass grafting, in acute myocardial infarction and in cardiotoxicity from cancer therapy are detailed. The second part keeps the focus on ROS providing a comprehensive overview of molecular and cellular mechanisms involved in ischemia/reperfusion injury. Starting from mitochondria as the main sources and targets of ROS in ischemic/reperfused myocardium, a complex network of cellular and extracellular processes is discussed, including relationships with Ca2+ homeostasis, thiol group redox balance, hydrogen sulfide modulation, cross-talk with NAPDH oxidases, exosomes, cytokines and growth factors. While mechanistic insights are needed to improve our current therapeutic approaches, advancements in knowledge of ROS-mediated processes indicate that detrimental facets of oxidative stress are opposed by ROS requirement for physiological and protective reactions. This inevitable contrast is likely to underlie unsuccessful clinical trials and limits the development of novel cardioprotective interventions simply based upon ROS removal.

Biallelic MAD2L1BP (p31comet) mutation is associated with mosaic aneuploidy and juvenile granulosa cell tumors.

MAD2L1BP-encoded p31comet mediates Trip13-dependent disassembly of Mad2- and Rev7-containing complexes and, through this antagonism, promotes timely spindle assembly checkpoint (SAC) silencing, faithful chromosome segregation, insulin signaling, and homology-directed repair (HDR) of DNA double-strand breaks. We identified a homozygous MAD2L1BP nonsense variant, R253*, in 2 siblings with microcephaly, epileptic encephalopathy, and juvenile granulosa cell tumors of ovary and testis. Patient-derived cells exhibited high-grade mosaic variegated aneuploidy, slowed-down proliferation, and instability of truncated p31comet mRNA and protein. Corresponding recombinant p31comet was defective in Trip13, Mad2, and Rev7 binding and unable to support SAC silencing or HDR. Furthermore, C-terminal truncation abrogated an identified interaction of p31comet with tp53. Another homozygous truncation, R227*, detected in an early-deceased patient with low-level aneuploidy, severe epileptic encephalopathy, and frequent blood glucose elevations, likely corresponds to complete loss of function, as in Mad2l1bp-/- mice. Thus, human mutations of p31comet are linked to aneuploidy and tumor predisposition.

Short anagen hair syndrome: association with mono- and biallelic variants in WNT10A and a genetic overlap with male pattern hair loss.

BACKGROUND: Short anagen hair (SAH) is a rare paediatric hair disorder characterized by a short anagen phase, an inability to grow long scalp hair and a negative psychological impact. The genetic basis of SAH is currently unknown. OBJECTIVES: To perform molecular genetic investigations in 48 individuals with a clinical phenotype suggestive of SAH to identify, if any, the genetic basis of this condition. METHODS: Exome sequencing was performed in 27 patients diagnosed with SAH or with a complaint of short, nongrowing hair. The cohort was screened for variants with a minor allele frequency (MAF) < 5% in the general population and a Combined Annotation Dependent Depletion (CADD) score > 15, to identify genes whose variants were enriched in this cohort. Sanger sequencing was used for variant validation and screening of 21 additional individuals with the same clinical diagnosis and their relatives. Genetic association testing of SAH-related variants for male pattern hair loss (MPHL) was performed using UK Biobank data. RESULTS: Analyses revealed that 20 individuals (42%) carried mono- or biallelic pathogenic variants in WNT10A. Rare WNT10A variants are associated with a phenotypic spectrum ranging from no clinical signs to severe ectodermal dysplasia. A significant association was found between WNT10A and SAH, and this was mostly observed in individuals with light-coloured hair and regression of the frontoparietal hairline. Notably, the most frequent variant in the cohort [c.682T>A;p.(Phe228Ile)] was in linkage disequilibrium with four common WNT10A variants, all of which have a known association with MPHL. Using UK Biobank data, our analyses showed that c.682T>A;p.(Phe228Ile) and one other variant identified in the SAH cohort are also associated with MPHL, and partially explain the known associations between WNT10A and MPHL. CONCLUSIONS: Our results suggest that WNT10A is associated with SAH and that SAH has a genetic overlap with the common phenotype MPHL. The presumed shared biologic effect of WNT10A variants in SAH and MPHL is a shortening of the anagen phase. Other factors, such as modifier genes and sex, may also play a role in the clinical manifestation of hair phenotypes associated with the WNT10A locus.

Transcatheter interventions for left-sided valvular heart disease complicated by cardiogenic shock: a consensus statement from the European Association of Percutaneous Cardiovascular Interventions (EAPCI) in collaboration with the Association for Acute Cardiovascular Care (ACVC) and the ESC Working Group on Cardiovascular Surgery.

Valvular heart disease (VHD) is one of the most frequent causes of heart failure (HF) and is associated with poor prognosis, particularly among patients with conservative management. The development and improvement of catheter-based VHD interventions have broadened the indications for transcatheter valve interventions from inoperable/high-risk patients to younger/lower-risk patients. Cardiogenic shock (CS) associated with severe VHD is a clinical condition with a very high risk of mortality for which surgical treatment is often deemed a prohibitive risk. Transcatheter valve interventions might be a promising alternative in this setting given that they are less invasive. However, supportive scientific evidence is scarce and often limited to small case series. Current guidelines on VHD do not contain specific recommendations on how to manage patients with both VHD and CS. The purpose of this clinical consensus statement, developed by a group of international experts invited by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) Scientific Documents and Initiatives Committee, is to perform a review of the available scientific evidence on the management of CS associated with left-sided VHD and to provide a rationale and practical approach for the application of transcatheter valve interventions in this specific clinical setting.

Trigger-Associated Clinical Implications and Outcomes in Takotsubo Syndrome: Results From the Multicenter GEIST Registry.

Background Takotsubo syndrome is usually triggered by a stressful event. The type of trigger seems to influence the outcome and should therefore be considered separately. Methods and Results Patients included in the GEIST (German-Italian-Spanish Takotsubo) registry were categorized according to physical trigger (PT), emotional trigger (ET), and no trigger (NT) of Takotsubo syndrome. Clinical characteristics as well as outcome predictors were analyzed. Overall, 2482 patients were included. ET was detected in 910 patients (36.7%), PT in 885 patients (34.4%), and NT was observed in 717 patients (28.9%). Compared with patients with PT or NT, patients with ET were younger, less frequently men, and had a lower prevalence of comorbidities. Adverse in-hospital events (NT: 18.8% versus PT: 27.1% versus ET: 12.1%, P<0.001) and long-term mortality rates (NT: 14.4% versus PT: 21.6% versus ET: 8.5%, P<0.001) were significantly lower in patients with ET. Increasing age (P<0.001), male sex (P=0.007), diabetes (P<0.001), malignancy (P=0.002), and a neurological disorder (P<0.001) were associated with a higher risk of long-term mortality, while chest pain (P=0.035) and treatment with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (P=0.027) were confirmed as independent predictors for a lower risk of long-term mortality. Conclusions Patients with ET have better clinical conditions and a lower mortality rate. Increasing age, male sex, malignancy, a neurological disorder, chest pain, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and diabetes were confirmed as predictors of long-term mortality.

Direct assessment of microcirculation in shock: a randomized-controlled multicenter study.

PURPOSE: Shock is a life-threatening condition characterized by substantial alterations in the microcirculation. This study tests the hypothesis that considering sublingual microcirculatory perfusion variables in the therapeutic management reduces 30-day mortality in patients admitted to the intensive care unit (ICU) with shock. METHODS: This randomized, prospective clinical multicenter trial-recruited patients with an arterial lactate value above two mmol/L, requiring vasopressors despite adequate fluid resuscitation, regardless of the cause of shock. All patients received sequential sublingual measurements using a sidestream-dark field (SDF) video microscope at admission to the intensive care unit (± 4 h) and 24 (± 4) hours later that was performed blindly to the treatment team. Patients were randomized to usual routine or to integrating sublingual microcirculatory perfusion variables in the therapy plan. The primary endpoint was 30-day mortality, secondary endpoints were length of stay on the ICU and the hospital, and 6-months mortality. RESULTS: Overall, we included 141 patients with cardiogenic (n = 77), post cardiac surgery (n = 27), or septic shock (n = 22). 69 patients were randomized to the intervention and 72 to routine care. No serious adverse events (SAEs) occurred. In the interventional group, significantly more patients received an adjustment (increase or decrease) in vasoactive drugs or fluids (66.7% vs. 41.8%, p = 0.009) within the next hour. Microcirculatory values 24 h after admission and 30-day mortality did not differ [crude: 32 (47.1%) patients versus 25 (34.7%), relative risk (RR) 1.39 (0.91-1.97); Cox-regression: hazard ratio (HR) 1.54 (95% confidence interval (CI) 0.90-2.66, p = 0.118)]. CONCLUSION: Integrating sublingual microcirculatory perfusion variables in the therapy plan resulted in treatment changes that do not improve survival at all.

Step by step daily management of short-term mechanical circulatory support for cardiogenic shock in adults in the intensive cardiac care unit: a clinical consensus statement of the Association for Acute CardioVascular Care of the European Society of Cardiology SC, the European Society of Intensive Care Medicine, the European branch of the Extracorporeal Life Support Organization, and the European Association for Cardio-Thoracic Surgery.

The use of mechanical circulatory support using percutaneous ventricular assist devices (pVAD) has increased rapidly during the last decade without substantial new evidence for their effect on outcome. In addition, many gaps in knowledge still exist such as timing and duration of support, haemodynamic monitoring, management of complications, concomitant medical therapy, and weaning protocols. This clinical consensus statement summarizes the consensus of an expert panel of the Association for Acute CardioVascular Care, European Society of Intensive Care Medicine, European Extracorporeal Life Support Organization, and European Association for Cardio-Thoracic Surgery. It provides practical advice regarding the management of patients managed with pVAD in the intensive care unit based on existing evidence and consensus on best current practice.

Expanding the phenotypic spectrum and clinical severity associated with WLS gene.

WLS (Wnt ligand secretion mediator or Wntless) orchestrates the secretion of all Wnt proteins, a family of evolutionary conserved proteins, involved in Wnt signaling pathway that has many essential biological functions including the regulation of development, cell proliferation, migration and apoptosis. Biallelic variants in WLS have recently been described in 10 patients with pleiotropic multiple congenital anomalies (MCA) known as Zaki syndrome. We identified a likely disease-causing variant in WLS (c.1579G>A, p.Gly527Arg) in a boy presented with a broad range of MCA including microcephaly, facial dysmorphism, alopecia, ophthalmologic anomalies, and complete soft tissue syndactyly. These features were reminiscent of Zaki syndrome although variable clinical severity was observed. In a detailed clinical assessment, our patient also displayed microphthalmia, dental anomalies, skeletal dysplasia with spontaneous fractures and Dandy-Walker malformation. As such, we extend the phenotype linked to Zaki syndrome. This study further highlights the importance of a thorough clinical evaluation to delineate the phenotypic spectrum associated with WLS variants and suggests that genotype-phenotype correlations due to variant localization seems likely. However, future work on additional patients and more functional studies may give further insights into genotype-phenotype correlations and the complex function of WLS.

Incidence and outcomes of emergency intraprocedural surgical conversion during transcatheter aortic valve implantation: Insights from a large tertiary care centre.

OBJECTIVE: During a transcatheter aortic valve implant (TAVI) procedure, intraprocedural complications that are manageable only by conversion to emergency open-heart surgery (E-OHS) occasionally occur. Contemporary data on the incidence and outcome of TAVI patients undergoing E-OHS are scarce. This study aimed to evaluate early and midterm outcomes following E-OHS of patients undergoing TAVI in a large tertiary care centre with immediate surgical backup availability for all TAVI procedures over a 15-year period. METHODS: Data from all patients undergoing transfemoral TAVI between 2006 and 2020 at the Heart Centre Leipzig were analysed. The study time was divided into 3 periods: 2006-2010 (P1), 2011-2015 (P2) and 2016-2020 (P3). Patients were grouped according to their surgical risk (high risk: EuroSCORE II ≥ 6%; low/intermediate risk: EuroSCORE II <6%). Primary outcomes were intraprocedural and in-hospital death and 1-year survival. RESULTS: During the study period, a total of 6903 patients underwent transfemoral TAVI. Among them, 74 (1.1%) required E-OHS [high risk, n = 66 (89.2%); low/intermediate risk, n = 8 (10.8%)]. The rate of patients requiring E-OHS was 3.5% (20/577 patients), 1.8% (35/1967 patients) and 0.4% (19/4359 patients) in study periods P1 to P3, respectively (P < 0.001). The proportion of patients who had E-OHS who were low/intermediate risk increased considerably over time (P1:0%; P28.6%; P3:26.3%; P = 0.077). Intraprocedural deaths occurred in 10 patients (13.5%), all of whom were high-risk. In-hospital mortality was 62.1% in high-risk patients and 12.5% in low/intermediate risk patients (P = 0.007). One-year survival was 37.8% in all patients undergoing E-OHS, 31.8% in high-risk patients and 87.5% in low/intermediate risk patients (log-rank P = 0.002). CONCLUSIONS: In-hospital and 1-year survival rates following E-OHS are higher in low/intermediate risk than in high-risk patients undergoing TAVI. An on-site cardiac surgical department with immediately available E-OHS capabilities is an important component of the TAVI team.
