Performance of the recommended ESC/EASD cardiovascular risk stratification model in comparison to SCORE and NT-proBNP as a single biomarker for risk prediction in type 2 diabetes mellitus.

BACKGROUND: Recently, the European Society of Cardiology (ESC) and European Association for the Society of Diabetes (EASD) introduced a new cardiovascular disease (CVD) risk stratification model to aid further treatment decisions in individuals with diabetes. Our study aimed to investigate the prognostic performance of the ESC/EASD risk model in comparison to the Systematic COronary Risk Evaluation (SCORE) risk model and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in an unselected cohort of type 2 diabetes mellitus (T2DM). METHODS AND RESULTS: A total of 1690 T2DM patients with a 10-year follow up for fatal CVD and all-cause death and a 5-year follow up for CVD and all-cause hospitalizations were analyzed. According to ESC/EASD risk criteria 25 (1.5%) patients were classified as moderate, 252 (14.9%) high, 1125 (66.6%) very high risk and 288 (17.0%) were not classifiable. Both NT-proBNP and SCORE risk model were associated with 10-year CVD and all-cause death and 5-year CVD and all-cause hospitalizations while the ESC/EASD model was only associated with 10-year all-cause death and 5-year all-cause hospitalizations. NT-proBNP and SCORE showed significantly higher C-indices than the ESC/EASD risk model for CVD death [0.80 vs. 0.53, p < 0.001; 0.64 vs. 0.53, p = 0.001] and all-cause death [0.73, 0.66 vs. 0.52, p < 0.001 for both]. The performance of SCORE improved in a subgroup without CVD aged 40-64 years compared to the unselected cohort, while NT-proBNP performance was robust across all groups. CONCLUSION: The new introduced ESC/EASD risk stratification model performed limited compared to SCORE and single NT-proBNP assessment for predicting 10-year CVD and all-cause fatal events in individuals with T2DM.

Increased concentrations of bioactive adrenomedullin subsequently to angiotensin-receptor/neprilysin-inhibitor treatment in chronic systolic heart failure.

AIMS: The clinically investigated rationale for neprilysin (NEP)-inhibition by angiotensinreceptor-NEPinhibitor (ARNi) therapy is to induce elevations in endogenous natriuretic peptides. NEP, however, cleaves a broad spectrum of substrates, which partially hold significant implications in heart failure with reduced ejection fraction (HFrEF). The effect of NEP inhibition on these peptides has not been investigated thoroughly. This study explored the response of adrenomedullin (ADM) regulation to the initiation of ARNi. METHODS: Seventy-four patients with stable HFrEF and initiation of ARNi were prospectively enrolled, 67 patients on continuous angiotensin-converting-enzyme inhibitor(ACEi)/angiotensin-receptor blocker (ARB) therapy served as control. Plasma bioactive-ADM (bio-ADM), mid-regional-pro-ADM (MR-proADM), B-typenatriuretic peptide (BNP) and N-terminal-pro-BNP (NT-proBNP) were determined at baseline, short-term, 1-year and 2-year follow up. RESULTS: Following ARNi initiation both bio-ADM and MR-proADM concentrations were significantly increased at early and long-term follow up (bio-ADM [pg/mL]: 26.0 [interquartile range {IQR}: 17.7-37.5] vs. 50.8 [IQR: 36.5-78.1] vs. 54.6 [IQR: 42.0-97.1] vs. 57.4 [IQR: 48.5-161.6]; MR-proADM [nmol/L]: 0.87 [IQR: 0.64-1.12] vs. 1.25 [IQR: 0.93-1.79] vs. 1.42 [IQR: 0.95-1.90] vs. 1.60 [IQR: 1.12-2.46], P < .0001 for all). The ratios bio-ADM/MR-proADM and BNP/NT-proBNP increased during ARNi-therapy proving improved availability of bioactive peptides. The proportional increase of bio-ADM markedly exceeded BNP increase. Patients converted to ARNi showed similar biomarker patterns irrespective of baseline renin-angiotensin system blocker therapy, i.e. ACEi or ARB (P > .05 for all), indicating that activation of the ADM-axis arises particularly from NEPinhibition. CONCLUSION: The significant increase of MR-proADM and bio-ADM together with an elevated bioADM/MR-proADM ratio suggest both enhanced formation and reduced breakdown of bioactive ADM following the initiation of ARNi. Activation of the ADM-axis represents a so far unrecognized effect of ARNi.

Destabilization in self-ratings of the psychotherapeutic process is associated with better treatment outcome in patients with mood disorders.

Objective: While destabilization periods characterized by high variability and turbulence in a patient's psychological state might seem obstructive for psychotherapy, a complex systems approach to psychopathology predicts that these periods are actually beneficial as they indicate possibilities for reorganization within the patient. The present study tested the hypothesis that destabilization is related to better treatment outcome.Method: 328 patients who received psychotherapy for mood disorders completed daily self-ratings about their psychotherapeutic process. A continuous measure of destabilization was defined as the relative strength of the highest peak in dynamic complexity, a measure for variability and turbulence, in the self-ratings of individual patients.Results: Destabilization was found to be related to better treatment outcome. When improvers and non-improvers were analyzed separately, destabilization was found to be related to better treatment outcome in improvers but not in non-improvers.Conclusions: Destabilization in daily self-ratings of the psychotherapeutic process is associated with better treatment outcome. The identification of destabilization periods in process-monitoring data is clinically relevant. During destabilization, patients are believed to be increasingly sensitive to the effects of therapy. Clinicians could tailor their interventions to these sensitive periods.

GDF-15 in solid vs non-solid treatment-naïve malignancies.

AIM: GDF-15 is an established cardiovascular risk marker but is equally implicated in tumour biology. Elevated levels of GDF-15 have indeed been observed in distinct tumour entities. This study aimed to explore the relation of GDF-15 to other cardiac biomarkers and the general association of GDF-15 on prognosis in an unselected cohort of treatment-naïve cancer patients. METHODS: We prospectively enrolled 555 consecutive patients at time of diagnosis of malignant disease prior receiving anticancer therapy. Plasma GDF-15 concentrations were determined alongside other cardiac and routine laboratory markers. All-cause mortality was defined as primary endpoint. RESULTS: GDF-15 levels were 338 ng/L (IQR:205-534) for the total cohort, and values were comparable for different tumour entities except breast cancer. Metastatic disease was characterized by higher plasma GDF-15 [435 ng/L (IQR:279-614) vs 266 ng/L (IQR:175-427), P < .001]. GDF-15 correlated positively with inflammatory status reflected by CRP, SAA and IL-6 [r = .31, P < .001, r = .23, P < .001 and r = .14, P = .002] and cardiac biomarkers as NT-proBNP, hsTnT, MR-proADM and CT-proET-1 [r = .46; r = .46; r = .59 and r = .50; P < .001 for all]. GDF-15 was significantly associated with all-cause mortality after multivariate adjustment [adj.HR for ln(GDF-15) 1.78, 95%CI:1.47-2.16, P < .001]. There was a significant interaction between solid and haematological malignancies with loss of association of GDF-15 with outcome in myelodysplastic and myeloproliferative disease. CONCLUSIONS: Elevated plasma GDF-15 is associated with progressing disease severity and poor prognosis in solid tumours of treatment-naïve cancer patients. GDF-15 increase is accompanied by worsening systemic inflammation and a subclinical functional impairment of different organs including the heart. GDF-15 represents a promising target for our pathophysiologic understanding in cardio-oncology linking conditions of both cardiac and neoplastic disease.

Refining the prognostic impact of functional mitral regurgitation in chronic heart failure.

Aims: Significant efforts are currently undertaken to reduce functional mitral regurgitation (FMR) in patients with chronic heart failure in the hope to improve prognosis. We aimed to assess the prognostic impact of FMR in heart failure with reduced ejection fraction (HFrEF) under optimal medical therapy (OMT) and various conditions of HFrEF. We further intended to identify a heart failure phenotype, where FMR is most likely a driving force and not a mere bystander of the disease. Methods and results: We prospectively included 576 consecutive HFrEF patients into our long-term observational study. Functional [i.e. New York Heart Association (NYHA) class], echocardiographic, invasive haemodynamic, and biochemical (i.e. NT-proBNP, MR-proANP, MR-proADM, CT-proET-1, copeptin) measurements were performed at baseline. During a median follow-up of 62 months (interquartile range 52-76), 47% of patients died. Severe FMR was a significant predictor of mortality [hazard ratio (HR) 1.76, 95% confidence interval (CI) 1.34-2.30; P < 0.001], independent of clinical (adjusted HR 1.61, 95% CI 1.22-2.12; P = 0.001), and echocardiographic (adjusted HR 1.46, 95% CI 1.09-1.94; P = 0.01) confounders, OMT (adjusted HR 1.81, 95% CI 1.25-2.63; P = 0.002), and neurohumoral activation (adjusted HR 1.38, 95% CI 1.03-1.84; P = 0.03). Subanalysis revealed that severe FMR was associated with poor outcome in an intermediate-failure phenotype of HFrEF i.e. patients with NYHA class II (adjusted HR 2.17, 95% CI 1.07-4.44; P = 0.03) and III (adjusted HR 1.80, 95% CI 1.17-2.77; P = 0.008), moderately reduced left ventricular function (adjusted HR 2.37, 95% CI 1.36-4.12; P = 0.002), and within the second quartile (871-2360 pg/mL) of NT-proBNP (adjusted HR 2.16, 95% CI 1.22-3.86; P = 0.009). Conclusion: In a patient cohort under OMT, the adverse prognostic impact of FMR is given predominantly in a sub-cohort of a specific intermediate-failure phenotype-well-defined functionally, haemodynamically, biochemically, and morphologically.

Low- and High-renin Heart Failure Phenotypes with Clinical Implications.

BACKGROUND: Blockade of the renin-angiotensin system (RAS) represents a main strategy in the therapy of heart failure with reduced ejection fraction (HFrEF), but the role of active renin concentration (ARC) for guiding therapy in the presence of an RAS blockade remains to be established. This study assessed angiotensin profiles of HFrEF patients with distinct RAS activations as reflected by ARC. METHODS: Two cohorts of stable chronic HFrEF patients on optimal medical treatment (OMT) were enrolled. We assessed ARC and all known circulating angiotensin metabolites, including AngI and AngII, by mass spectrometry to investigate the effect of different therapy modalities. Low- and high-renin HFrEF patients were identified by ARC screening and subsequently characterized by their angiotensin profiles. RESULTS: Although different modes of RAS blockade resulted in typical AngII/AngI ratios, concentrations of (AngI+AngII) strongly correlated with ARC [r = 0.95, P < 0.001] independent of therapy mode. Despite RAS blocker treatment with angiotensin-converting enzyme inhibitors (ACE-I) or angiotensin II type 1 receptor blockers (ARB), which anticipated ARC upregulation, about 30% of patients showed lower/normal range ARC values. ARC did not correlate with N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations and New York Heart Association (NYHA) stages. Angiotensin concentrations were profoundly diminished for the low-ARC group compared with the high-ARC group: AngI [6.4 ng/L (IQR: 2.1-12.5) vs 537.9 ng/L (IQR: 423.1-728.4), P < 0.001 for ACE-I; and 4.5 ng/L (IQR: 1.4-11.2) vs 203.0 ng/L (IQR: 130.2-247.9), P = 0.003 for ARB] and AngII [<1.4 ng/L (IQR: <1.4-1.5) vs 6.1 ng/L (IQR: 2.0-11.1), P = 0.002 for ACE-I and 4.7 ng/L (IQR: <1.4-12.3) vs 206.4 ng/L (IQR: 142.2-234.4), P < 0.001 for ARB]. CONCLUSIONS: In addition to NT-proBNP and NYHA stages, ARC enables classification of HFrEF patients receiving OMT into more distinguished neurohumoral HFrEF phenotypes, offering a rationale for adaptive therapeutic interventions.

N-terminal B-type natriuretic peptide (NT-proBNP) is associated with disease severity in multiple myeloma.

BACKGROUND: Elevated levels of cardiovascular markers including N-terminal B-type natriuretic peptide (NT-proBNP) have been shown to be associated with disease severity and mortality in an unselected population of cancer patients without cardiac disease. The aim of this study was to investigate whether NT-proBNP levels are related to disease severity in multiple myeloma (MM) and to assess the natural course of NT-proBNP levels throughout disease progression. MATERIALS AND METHODS: We retrospectively analysed a total of 118 patients with MM, who were followed up routinely. NT-proBNP, beta-2-microglobulin (B2M) and levels of plasma cell-derived light chains were measured at baseline and follow-up (FUP) visits. All-cause mortality was defined as primary study endpoint, and the correlation between NT-proBNP and disease severity reflected by B2M and the International Staging System (ISS) was assessed. RESULTS: During a median FUP of 845 (IQR:683-978) days, 31 patients (26%) died. NT-proBNP showed a highly significant positive correlation with B2M at first presentation [r = .65, P < .001] and increased significantly with progressing MM disease stage [133.3 pg/mL (IQR:51.5-282.0) for ISS stage 1, 487.4 pg/mL (IQR:123.8-738.3) for ISS stage 2 and 969.1 pg/mL (IQR:472.8-3748.0) for ISS stage 3, P < .001 between all groups]. During FUP, NT-proBNP levels rose significantly alongside other MM disease severity markers for patients experiencing the primary outcome [356.6 pg/mL (IQR:142.9-782.3) vs 862.9 pg/mL (IQR:338.8-4215.0), P < .001], whereas no significant changes in laboratory parameters could be detected for survivors. CONCLUSIONS: Elevated levels of the cardiovascular marker NT-proBNP are associated with disease severity in patients with MM.

GDF-15 Is Associated with Cancer Incidence in Patients with Type 2 Diabetes.

BACKGROUND: Diabetes has been linked epidemiologically to increased cancer incidence and mortality. Growth differentiation factor 15 (GDF-15) is increased in patients with diabetes and has recently been linked to the occurrence of cancer. We investigated whether circulating GDF-15 concentrations can predict the incidence of malignant diseases in a diabetic patient cohort already facing increased risk for cancer. METHODS: We prospectively enrolled a total of 919 patients with type 2 diabetes and no history of malignant disease, who were clinically followed up for 60 months. GDF-15, N-terminal pro-B-type natriuretic peptide and troponin T were measured at baseline; an additional 4 cardiovascular biomarkers were determined for a subpopulation (n = 259). Study end point was defined as the first diagnosis of any type of cancer during the follow-up period. RESULTS: During a median follow-up of 60 months, 66 patients (7.2%) were diagnosed with cancer. Baseline circulating GDF-15 concentrations were higher in patients that developed cancer over the follow-up period when compared to cancer-free patients. Increased GDF-15 concentrations were significantly associated with cancer incidence [crude hazard ratio (HR) per 1-IQR (interquartile range) increase 2.13, 95% CI 1.53-2.97, P < 0.001]. This effect persisted after multivariate adjustment with an adjusted HR of 1.86 (95% CI 1.22-2.84; P = 0.004). Among the 4 additionally tested cardiovascular markers in the subpopulation, only troponin T and C-terminal proendothelin-1 showed a significant association with future cancer incidence with unadjusted HRs of 1.71 (95% CI 1.28-2.28, P < 0.001) and 1.68 (95% CI 1.02-2.76, P = 0.042), respectively. CONCLUSIONS: Increased circulating concentrations of GDF-15 are associated with increased cancer incidence in patients with type 2 diabetes.

Outcome of conservative management vs. assist device implantation in patients with advanced refractory heart failure.

BACKGROUND: In patients with advanced refractory heart failure (HF) cardiac transplantation (HTX), conservative medical management and the implantation of a ventricular assist device (VAD) represent valuable options. The determination of the best therapeutic destination strategy for the individual patient remains a challenge. The aim of this study was to assess the clinical outcome in advanced refractory HF patients either managed conservatively receiving optimal contemporary medical therapy ('conservative'), or who who underwent pulsatile flow VAD ('pVAD') or continuous-flow VAD ('contVAD') implantation. MATERIALS AND METHODS: A total of 118 patients with INTERMACS profile >1 at baseline, who died, or fully completed a 24-month follow-up free from HTX were included into this retrospective analysis. All-cause mortality at 24 months was assessed and compared between the three groups. RESULTS: Fifty (42%) patients were managed conservatively, 25 (21%) received a pVAD and 43 (36%) a contVAD. NT-proBNP values were comparable between the three groups (median 4402 (IQR 2730-13390) pg/mL, 3580 (1602-6312) pg/mL and 3693 (2679-8065) pg/mL, P = 0·256). Mean survival was 18·6 (95% CI 16·2-21·0) months for patients managed conservatively, 7·0 (3·9-10·0) for pVAD and 20·5 (18·2-22·8) for contVAD (overall log-rank test P < 0·001). Conservatively managed patients spent a mean of 22·4 (95% CI 22·1-22·8), pVAD 17·7 (15·4-20·1) and contVAD 21·6 (21·2-22·1) months out of hospital (conservative vs. pVAD P < 0·001; conservative vs. contVAD P = 0·015; pVAD vs. contVAD P < 0·001). CONCLUSIONS: In accordance with the literature, contVAD resulted in a significantly better clinical outcome than pVAD implantation. However, conservative management with current optimal medical therapy appears to remain a valuable option for patients with advanced HF.

Learning curve for the detection of pouch of Douglas obliteration and deep infiltrating endometriosis of the rectum.

STUDY QUESTION: How long does it take to be proficient in diagnosing pouch of Douglas (POD) obliteration and deep infiltrating endometriosis (DIE) of the rectum with transvaginal sonography (TVS)? SUMMARY ANSWER: Sonographers familiar with the general use of TVS are expected to be proficient in the diagnosis of endometriosis nodules of the rectum and the detection of POD obliteration using the 'sliding sign' after ∼40 examinations, performed in a referral clinic for pelvic pain. WHAT IS ALREADY KNOWN: With rectal DIE, the reasons for the obvious diagnostic problems are complex. Menstrual pain or cramps are still considered to be 'normal' and do not provide a reason for patients and even health-care providers to seek expert help. Furthermore, the performance of TVS for diagnosing pelvic endometriosis has been shown to be accurate only in experienced hands. STUDY DESIGN, SIZE AND DURATION: This prospective study included 121 selected patients with suspected endometriosis. PARTICIPANTS/MATERIALS, SETTING, METHODS: Symptomatic patients, referred to a pelvic pain clinic, were examined by an expert sonographer (E.S.) and consecutively by two trainees (T1/2). MAIN RESULTS AND THE ROLE OF CHANCE: The learning curve using the cumulative sum shows that the trainees, listed as T1/T2, reached the predefined level of proficiency in detecting bowel nodules after examining 42 and 37 patients, for T1 and T2, respectively. The prevalence rate of bowel nodules demonstrated by the ES was 21%. The sensitivity, specificity, positive and negative predictive values (PPV, NPV) as well as the accuracy for TVS of T1 and T2 in comparison with the results of ES were 72 and 89, 96 and 95, 87 and 80, 90 and 98, and 89 and 94%, respectively. The prevalence rate of POD obliteration, as demonstrated by a negative sliding sign, was 27%. The trainees reached the predefined level of proficiency after examining 42 and 33 patients, for T1 and T2, respectively. The sensitivity, specificity, PPV, NPV as well as the accuracy of TVS for T1 and T2 in comparison with the results of the ES were 83 and 89, 95 and 95, 91 and 80, 90 and 98, and 91 and 94%, respectively. LIMITATIONS, REASONS FOR CAUTION: We performed this analysis in a tertiary referral centre with a high number of advanced cases of DIE, not reflecting a standard population. WIDER IMPLICATION OF THE FINDINGS: Integrated in TVS training courses, typical sonographic video clips for DIE of the rectum, including the use of disease-specific signs, could help to improve diagnostic accuracy in DIE and shorten diagnostic delays. STUDY FUNDING/COMPETING INTERESTS: No funding was received for this study. None of the authors has any competing interests.

Serum Markers of Neurodegeneration Are Strongly Linked to Heart Failure Severity and Outcome.

BACKGROUND: Cognitive impairment is prevalent in patients with heart failure with reduced ejection fraction (HFrEF), affecting self-care and outcomes. Novel blood-based biomarkers have emerged as potential diagnostic tools for neurodegeneration. OBJECTIVES: This study aimed to assess neurodegeneration in HFrEF by measuring neurofilament light chain (NfL), total tau (t-tau), amyloid beta 40 (Aß40), and amyloid beta 42 (Aß42) in a large, well-characterized cohort. METHODS: The study included 470 patients with HFrEF from a biobank-linked prospective registry at the Medical University of Vienna. High-sensitivity single-molecule assays were used for measurement. Unplanned heart failure (HF) hospitalization and all-cause death were recorded as outcome parameters. RESULTS: All markers, but not the Aß42:Aß40 ratio, correlated with HF severity, ie, N-terminal pro-B-type natriuretic peptide and NYHA functional class, and comorbidity burden and were significantly associated with all-cause death and HF hospitalization (crude HR: all-cause death: NfL: 4.44 [95% CI: 3.02-6.53], t-tau: 5.04 [95% CI: 2.97-8.58], Aß40: 3.90 [95% CI: 2.27-6.72], and Aß42: 5.14 [95% CI: 2.84-9.32]; HF hospitalization: NfL: 2.48 [95% CI: 1.60-3.85], t-tau: 3.44 [95% CI: 1.95-6.04], Aß40: 3.13 [95% CI: 1.84-5.34], and Aß42: 3.48 [95% CI: 1.93-6.27]; P < 0.001 for all). These associations remained statistically significant after multivariate adjustment including N-terminal pro-B-type natriuretic peptide. The discriminatory accuracy of NfL in predicting all-cause mortality was comparable to the well-established risk marker N-terminal pro-B-type natriuretic peptide (C-index: 0.70 vs 0.72; P = 0.225), whereas the C-indices of t-tau, Aß40, Aß42, and the Aß42:Aß40 ratio were significantly lower (P < 0.05 for all). CONCLUSIONS: Neurodegeneration is directly interwoven with the progression of HF. Biomarkers of neurodegeneration, particularly NfL, may help identify patients potentially profiting from a comprehensive neurological work-up. Further research is necessary to test whether early diagnosis or optimized HFrEF treatment can preserve cognitive function.

Attitude is everything? The impact of workload, safety climate, and safety tools on medical errors: a study of intensive care units.

BACKGROUND: Hospitals face an increasing pressure toward efficiency and cost reduction while ensuring patient safety. This warrants a closer examination of the trade-off between production and protection posited in the literature for a high-risk hospital setting (intensive care). PURPOSES: On the basis of extant literature and concepts on both safety management and organizational/safety culture, this study investigates to which extent production pressure (i.e., increased staff workload and capacity utilization) and safety culture (consisting of safety climate among staff and safety tools implemented by management) influence the occurrence of medical errors and if/how safety climate and safety tools interact. METHODOLOGY/APPROACH: A prospective, observational, 48-hour cross-sectional study was conducted in 57 intensive care units. The dependent variable is the incidence of errors affecting those 378 patients treated throughout the entire observation period. Capacity utilization and workload were measured by indicators such as unit occupancy, nurse-to-patient/physician-to-patient ratios, levels of care, or NEMS scores. The safety tools considered include Critical Incidence Reporting Systems, audits, training, mission statements, SOPs/checklists, and the use of barcodes. Safety climate was assessed using a psychometrically validated four-dimensional questionnaire.Linear regression was employed to identify the effects of the predictor variables on error rate as well as interaction effects between safety tools and safety climate. FINDINGS: Higher workload has a detrimental effect on safety, whereas safety climate-unlike the examined safety tools-has a virtually equal opposite effect. Correlations between safety tools and safety climate as well as their interaction effects on error rate are mostly nonsignificant. PRACTICE IMPLICATIONS: Increased workload and capacity utilization increase the occurrence of medical error, an effect that can be offset by a positive safety climate but not by formally implemented safety procedures and policies.

Phase transitions between lower and higher level management learning in times of crisis: an experimental study based on synergetics.

Much has been written about the differences between single- and double-loop learning, or more general between lower level and higher level learning. Especially in times of a fundamental crisis, a transition between lower and higher level learning would be an appropriate reaction to a challenge coming entirely out of the dark. However, so far there is no quantitative method to monitor such a transition. Therefore we introduce theory and methods of synergetics and present results from an experimental study based on the simulation of a crisis within a business simulation game. Hypothesized critical fluctuations - as a marker for so-called phase transitions - have been assessed with permutation entropy. Results show evidence for a phase transition during the crisis, which can be interpreted as a transition between lower and higher level learning.

The best of both worlds? General principles of psychopathology in personalized assessment.

A complex systems approach to psychopathology proposes that general principles lie in the dynamic patterns of psychopathology, which are not restricted to specific psychological processes like symptoms or affect. Hence, it must be possible to find general change profiles in time series data of fully personalized questionnaires. In the current study, we examined general change profiles in personalized self-ratings and related these to four measures of treatment outcome (International Symptom Rating, 21-item Depression Anxiety and Stress Scale, daily symptom severity, and self-reflective capacity). We analyzed data of 404 patients with mood and/or anxiety disorders who completed daily self-ratings on personalized questionnaires during psychotherapy. For each patient, a principal component analysis was applied to the multivariate time series in order to retrieve an univariate person-specific time series. Then, using classification and regression methods, we examined these time series for the presence of general change profiles. The change profile classification yielded the following distribution of patients: no-shift (n = 55; 14%), gradual-change (n = 52; 13%), one-shift (n = 233; 58%), reversed-shift (n = 39; 10%) and multiple-shifts (n = 25; 6%). The multiple-shift group had better treatment outcome than the no-shift group on all outcome measures. The one-shift and gradual-change groups had better treatment outcome than the no-shift group on two and three outcome measures, respectively. Overall, this study illustrates that person-specific (idiographic) and general (nomothetic) aspects of psychopathology can be integrated in a complex systems approach to psychopathology, which may combine "the best of both worlds."

Obesity in heart failure with preserved ejection fraction with and without diabetes: risk factor or innocent bystander?

AIMS: Heart failure with preserved ejection fraction (HFpEF) is a condition that commonly coexists with type 2 diabetes mellitus (T2DM) and obesity. Whether the obesity-related survival benefit generally observed in HFpEF extends to individuals with concomitant T2DM is unclear. This study sought to examine the prognostic role of overweight and obesity in a large cohort of HFpEF with and without T2DM. METHODS AND RESULTS: This large-scale cohort study included patients with HFpEF enrolled between 2010 and 2020. The relationship between body mass index (BMI), T2DM, and survival was assessed. A total of 6744 individuals with HFpEF were included, of which 1702 (25%) had T2DM. Patients with T2DM had higher BMI values (29.4 kg/m2 vs. 27.1 kg/m2, P < 0.001), higher N-terminal pro-brain natriuretic peptide values (864 mg/dL vs. 724 mg/dL, P < 0.001), and a higher prevalence of numerous risk factors/comorbidities than those without T2DM. During a median follow-up time of 47 months (Q1-Q3: 20-80), 2014 (30%) patients died. Patients with T2DM had a higher incidence of fatal events compared with those without T2DM, with a mortality rate of 39.2% and 26.7%, respectively (P < 0.001). In the overall cohort, using the BMI category 22.5-24.9 kg/m2 as the reference group, the unadjusted hazard ratio (HR) for all-cause death was increased in patients with BMI <22.5 kg/m2 [HR: 1.27 (confidence interval 1.09-1.48), P = 0.003] and decreased in BMI categories ≥25 kg/m2. After multivariate adjustment, BMI remained significantly inversely associated with survival in non-T2DM, whereas survival was unaltered at a wide range of BMI in patients with T2DM. CONCLUSION: Among the various phenotypes of HFpEF, the T2DM phenotype is specifically associated with a greater disease burden. Higher BMI is linked to improved survival in HFpEF overall, while this effect neutralises in patients with concomitant T2DM. Advising BMI-based weight targets and weight loss may be pursued with different intensity in the management of HFpEF, particularly in the presence of T2DM.

Individuals with HFpEF and concomitant diabetes show a distinct phenotype particularly associated with a higher disease burden and worse outcome. The obesity paradox observed in individuals with heart failure may not be generalized to HFpEF patients with concomitant diabetes.

A streamlined, machine learning-derived approach to risk-stratification in heart failure patients with secondary tricuspid regurgitation.

AIMS: Secondary tricuspid regurgitation (sTR) is the most frequent valvular heart disease and has a significant impact on mortality. A high burden of comorbidities often worsens the already dismal prognosis of sTR, while tricuspid interventions remain underused and initiated too late. The aim was to examine the most powerful predictors of all-cause mortality in moderate and severe sTR using machine learning techniques and to provide a streamlined approach to risk-stratification using readily available clinical, echocardiographic and laboratory parameters. METHODS AND RESULTS: This large-scale, long-term observational study included 3359 moderate and 1509 severe sTR patients encompassing the entire heart failure spectrum (preserved, mid-range and reduced ejection fraction). A random survival forest was applied to investigate the most important predictors and group patients according to their number of adverse features.The identified predictors and thresholds, that were associated with significantly worse mortality were lower glomerular filtration rate (<60 mL/min/1.73m2), higher NT-proBNP, increased high sensitivity C-reactive protein, serum albumin < 40 g/L and hemoglobin < 13 g/dL. Additionally, grouping patients according to the number of adverse features yielded important prognostic information, as patients with 4 or 5 adverse features had a fourfold risk increase in moderate sTR [4.81(3.56-6.50) HR 95%CI, P < 0.001] and fivefold risk increase in severe sTR [5.33 (3.28-8.66) HR 95%CI, P < 0.001]. CONCLUSION: This study presents a streamlined, machine learning-derived and internally validated approach to risk-stratification in patients with moderate and severe sTR, that adds important prognostic information to aid clinical-decision-making.

Contemporary insights into the epidemiology, impact and treatment of secondary tricuspid regurgitation across the heart failure spectrum.

AIM: Tricuspid regurgitation secondary to heart failure (HF) is common with considerable impact on survival and hospitalization rates. Currently, insights into epidemiology, impact, and treatment of secondary tricuspid regurgitation (sTR) across the entire HF spectrum are lacking, yet are necessary for healthcare decision-making. METHODS AND RESULTS: This population-based study included data from 13 469 patients with HF and sTR from the Viennese community over a 10-year period. The primary outcome was long-term mortality. Overall, HF with preserved ejection fraction was the most frequent (57%, n = 7733) HF subtype and the burden of comorbidities was high. Severe sTR was present in 1514 patients (11%), most common among patients with HF with reduced ejection fraction (20%, n = 496). Mortality of patients with sTR was higher than expected survival of sex- and age-matched community and independent of HF subtype (moderate sTR: hazard ratio [HR] 6.32, 95% confidence interval [CI] 5.88-6.80, p < 0.001; severe sTR: HR 9.04; 95% CI 8.27-9.87, p < 0.001). In comparison to HF and no/mild sTR patients, mortality increased for moderate sTR (HR 1.58, 95% CI 1.48-1.69, p < 0.001) and for severe sTR (HR 2.19, 95% CI 2.01-2.38, p < 0.001). This effect prevailed after multivariate adjustment and was similar across all HF subtypes. In subgroup analysis, severe sTR mortality risk was more pronounced in younger patients (<70 years). Moderate and severe sTR were rarely treated (3%, n = 147), despite availability of state-of-the-art facilities and universal health care. CONCLUSION: Secondary tricuspid regurgitation is frequent, increasing with age and associated with excess mortality independent of HF subtype. Nevertheless, sTR is rarely treated surgically or percutaneously. With the projected increase in HF prevalence and population ageing, the data suggest a major burden for healthcare systems that needs to be adequately addressed. Low-risk transcatheter treatment options may provide a suitable alternative.

Inorganic phosphate and FGF-23 predict outcome in stable systolic heart failure.

BACKGROUND: Recent studies show associations between inorganic phosphate and risk of heart failure in the general population as well as between fibroblast growth factor 23 (FGF-23) and outcome in coronary heart disease. This study was carried out to assess whether circulating levels of inorganic phosphate and FGF-23, a new central hormone in mineral bone metabolism, predict outcome in systolic heart failure. MATERIALS AND METHODS: Ninety-nine consecutive outpatients with systolic heart failure were enrolled. Mean (SD) age was 61 years (11), mean left ventricular ejection fraction (LVEF) was 33% (10), 82 patients were men, median estimated creatinine clearance was 83 mL/min (Q(1) -Q(3) 58-106), median NTproBNP level was 803 pg/mL (Q(1) -Q(3) 404-2757), median inorganic phosphate was 1·12 mM (Q(1) -Q(3) 1·02-1·22), median FGF-23 was 39·02 pg/mL (Q(1) -Q(3) 32·45-55·86) and median follow-up was 35 months. Associations between inorganic phosphate, FGF-23 and endpoints were assessed using Cox regression analyses. RESULTS: Inorganic phosphate and FGF-23 levels were significantly higher (P < 0·001 and P = 0·009) in patients reaching the combined endpoint of cardiac hospitalization or death. FGF-23 (ln) predicted all-cause mortality (hazard ratio (HR) 5·042, P = 0·032) in a model adjusted for age, gender, estimated creatinine clearance, LVEF, New York Heart Association (NYHA) stage and NTproBNP level. Inorganic phosphate predicted heart failure hospitalization (HR 26·944, P = 0·021), cardiac hospitalization (HR 16·016, P = 0·017) and the combined endpoint (HR 13·294, P = 0·015) in models adjusted for the same co-variables. CONCLUSION: The results of this study demonstrate the independent prognostic value of inorganic phosphate and FGF-23 in heart failure even in the context of established risk markers.

[Therapy Process Questionnaire (TPQ) - a combined explorative and confirmatory factor analysis and psychometric properties]. / Der Therapie-Prozessbogen (TPB) ­ faktorenstruktur und psychometrische daten.

OBJECTIVES: This contribution looks at the factorial structure of the Therapy Process Questionnaire (TPQ), which is used for daily self-ratings of patients tested by internet-based ambulatory assessment devices. METHODS: A combined explorative and confirmatory factor analysis of the TPQ. The time-series data were generated by 149 patients treated in an inpatient setting. RESULTS: 23 out of 42 items included in the explorative version of the TPQ are represented onto five factors, which were identified by a first explorative factor analysis and then validated by a confirmative factor analysis. We report on the psychometric data of the subscales: internal consistency (Cronbach's α), mean of item-intercorrelation, and mean of item discrimination indices. CONCLUSION: The TPQ is useful for a high-frequency and equidistant (daily) assessment of psychotherapeutic change processes.
