RESUMO

AIMS: Iron deficiency (ID) is comorbid in up to 50% patients with heart failure (HF) and exacerbates disease burden. Ferric carboxymaltose (FCM) reduced HF hospitalizations and improved quality of life when used to treat ID at discharge in patients hospitalized for acute HF with left ventricular ejection fraction <50% in the AFFIRM-AHF trial. We quantified the effect of FCM on burden of disease and the wider pharmacoeconomic implications in France, Germany, Poland, Spain and Sweden. METHODS AND RESULTS: The per country eligible population was calculated, aligning with the 2021 European Society of Cardiology (ESC) HF guidelines and the AFFIRM-AHF trial. Changes in burden of disease with FCM versus standard of care (SoC) were represented by disability-adjusted life years (DALYs), hospitalization episodes and bed days, using AFFIRM-AHF data. A Markov model was adapted to each country to estimate cost-effectiveness and combined with epidemiology data to calculate the impact on healthcare budgets. Between 335 (Sweden) and 13 237 (Germany) DALYs were predicted to be avoided with FCM use annually. Fewer hospitalizations and shorter lengths of stay associated with FCM compared to SoC were projected to result in substantial annual savings in bed days, from 5215 in Sweden to 205 630 in Germany. In all countries, FCM was predicted to be dominant (cost saving with gains in quality-adjusted life years), resulting in net savings to healthcare budgets within 1 year. CONCLUSIONS: This comprehensive evaluation of FCM therapy highlights the potential benefits that could be realized through implementation of the ESC HF guideline recommendations regarding ID treatment.

RESUMO

Clonal hematopoiesis of indeterminate potential (CHIP), defined as the presence of somatic mutations in cancer-related genes in blood cells in the absence of hematological cancer, has recently emerged as an important risk factor for several age-related conditions, especially cardiovascular disease. CHIP is strongly associated with normal aging, but its role in premature aging syndromes is unknown. Hutchinson-Gilford progeria syndrome (HGPS) is an ultra-rare genetic condition driven by the accumulation of a truncated form of the lamin A protein called progerin. HGPS patients exhibit several features of accelerated aging and typically die from cardiovascular complications in their early teens. Previous studies have shown normal hematological parameters in HGPS patients, except for elevated platelets, and low levels of lamin A expression in hematopoietic cells relative to other cell types in solid tissues, but the prevalence of CHIP in HGPS remains unexplored. To investigate the potential role of CHIP in HGPS, we performed high-sensitivity targeted sequencing of CHIP-related genes in blood DNA samples from a cohort of 47 HGPS patients. As a control, the same sequencing strategy was applied to blood DNA samples from middle-aged and elderly individuals, expected to exhibit a biological age and cardiovascular risk profile similar to HGPS patients. We found that CHIP is not prevalent in HGPS patients, in marked contrast to our observations in individuals who age normally. Thus, our study unveils a major difference between HGPS and normal aging and provides conclusive evidence that CHIP is not frequent in HGPS and, therefore, is unlikely to contribute to the pathophysiology of this accelerated aging syndrome.

RESUMO

Neuroendocrine carcinoma of the gallbladder (NECGB) is a rare, aggressive tumor with a poor prognosis. There are two main categories, well-differentiated NECGB and poorly differentiated NECGB, the latter with a worse prognosis. The clinical presentation is non-specific, but the occurrence is more frequent in women with cholelithiasis. Histologic and immuno-histochemical confirmation is required to establish the diagnosis. Treatment is primarily surgery with or without adjuvant chemotherapy. We present the case of a 43-year-old woman with pain in the right upper quadrant, diagnosed with NECGB following cholecystectomy. Subsequently, she received cycles of chemotherapy.

RESUMO

INTRODUCTION: Retinoblastoma is a curable cancer when management is early and prompt. OBJECTIVE: To describe the epidemiological, clinical and therapeutic aspects of retinoblastoma. MATERIALS AND METHODS: A retrospective study was carried out from January 2014 to December 2018 (5 years) at the department of ophthalmology in Campus-University Teaching Hospital, Lomé, Togo. It focused on children with retinoblastoma. It included patients with diagnosis supported by ocular ultrasonography, orbito-cerebral computed tomography scan and/or histopathological examination. RESULTS: Among the 75 children with ocular cancer, 26 (34.7%) were diagnosed with retinoblastoma. The mean age at presentation was 31 months. The mean time from symptom onset to diagnosis was 15 months. A predominance of proptosis (65.4%), unilateral involvement (76.9%), extraocular tumor extension (65.4%) and endophytic form (96.15%) was found. Of the 32 eyes with retinoblastoma, 7 (21.9%) were enucleated after a mean time from diagnosis to enucleation of 6 months. Two cases of complete remission, 3 cases of tumor recurrence, and 2 cases lost to follow-up were noted. CONCLUSION: In our setting, retinoblastoma is a frequent childhood ocular cancer. It is important to improve the management of retinoblastoma as well as education of the parents.

RESUMO

AIMS: Prior studies have not fully characterized the haemodynamic effects of the angiotensin receptor-neprilysin inhibitor (ARNI) sacubitril/valsartan in heart failure with preserved ejection fraction and pulmonary hypertension (HFpEF-PH). The aim of the Treatment of PH With Angiotensin II Receptor Blocker and Neprilysin Inhibitor in HFpEF Patients With CardioMEMS Device (ARNIMEMS-HFpEF) study is to assess pulmonary artery pressure (PAP) dynamics by means of implanted PAP monitors in patients with HFpEF-PH treated with sacubitril/valsartan. METHODS AND RESULTS: This single-arm, investigator-initiated, interventional study included 14 consecutive ambulatory symptomatic HFpEF-PH patients who underwent CardioMEMS implantation prior to enrolment [mean ejection fraction 60.4 ± 7.2%, baseline mean PAP (mPAP) 33.9 ± 7.6 mmHg]. Daily PAP values were examined during three periods: a 6 week period after CardioMEMS implantation and before sacubitril/valsartan treatment (pre-ARNI), a 6 week period with sacubitril/valsartan treatment (ARNI ON), and a 6 week period of sacubitril/valsartan withdrawal (ARNI OFF). The primary endpoint was change in mPAP with and without sacubitril/valsartan. Secondary endpoints included changes in 6 min walking distance, B-line sum in lung ultrasound, and quality of life (QoL). During the study period, 1717 mPAP measurements were recorded. Between pre-ARNI vs. ARNI ON, mPAP significantly declined by -4.99 mmHg [95% confidence interval (CI) -5.55 to -4.43]. Between ARNI ON vs. ARNI OFF, mPAP significantly increased by +2.84 mmHg [95% CI +2.26 to +3.42]. Between pre-ARNI vs. ARNI ON, we found an improvement in 6 min walking distance, B-lines, and QoL. Mean loop diuretic management did not differ between periods. CONCLUSIONS: Sacubitril/valsartan significantly reduced mPAP in patients with HFpEF-PH, independent of loop diuretic management, together with improvement in functional capacity, lung congestion, and QoL. Sacubitril/valsartan may be a therapeutic alternative in HFpEF-PH.

RESUMO

AIMS: Patients with heart failure (HF) and iron deficiency experience poor health-related quality of life (HRQoL). We evaluated the impact of intravenous (IV) ferric carboxymaltose (FCM) vs. placebo on HRQoL for the AFFIRM-AHF population. METHODS AND RESULTS: The baseline 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12), which was completed for 1058 (535 and 523) patients in the FCM and placebo groups, respectively, was administered prior to randomization and at Weeks 2, 4, 6, 12, 24, 36, and 52. The baseline KCCQ-12 overall summary score (OSS) mean ± standard error was 38.7 ± 0.9 (FCM group) and 37.1 ± 0.8 (placebo group); corresponding values for the clinical summary score (CSS) were 40.9 ± 0.9 and 40.1 ± 0.9. At Week 2, changes in OSS and CSS were similar for FCM and placebo. From Week 4 to Week 24, patients assigned to FCM had significantly greater improvements in OSS and CSS scores vs. placebo [adjusted mean difference (95% confidence interval, CI) at Week 4: 2.9 (0.5-5.3, P = 0.018) for OSS and 2.8 (0.3-5.3, P = 0.029) for CSS; adjusted mean difference (95% CI) at Week 24: 3.0 (0.3-5.6, P = 0.028) for OSS and 2.9 (0.2-5.6, P = 0.035) for CSS]. At Week 52, the treatment effect had attenuated but remained in favour of FCM. CONCLUSION: In iron-deficient patients with HF and left ventricular ejection fraction <50% who had stabilized after an episode of acute HF, treatment with IV FCM, compared with placebo, results in clinically meaningful beneficial effects on HRQoL as early as 4 weeks after treatment initiation, lasting up to Week 24.

RESUMO

BACKGROUND: The diagnosis of acute myocarditis typically requires either endomyocardial biopsy (which is invasive) or cardiovascular magnetic resonance imaging (which is not universally available). Additional approaches to diagnosis are desirable. We sought to identify a novel microRNA for the diagnosis of acute myocarditis. METHODS: To identify a microRNA specific for myocarditis, we performed microRNA microarray analyses and quantitative polymerase-chain-reaction (qPCR) assays in sorted CD4+ T cells and type 17 helper T (Th17) cells after inducing experimental autoimmune myocarditis or myocardial infarction in mice. We also performed qPCR in samples from coxsackievirus-induced myocarditis in mice. We then identified the human homologue for this microRNA and compared its expression in plasma obtained from patients with acute myocarditis with the expression in various controls. RESULTS: We confirmed that Th17 cells, which are characterized by the production of interleukin-17, are a characteristic feature of myocardial injury in the acute phase of myocarditis. The microRNA mmu-miR-721 was synthesized by Th17 cells and was present in the plasma of mice with acute autoimmune or viral myocarditis but not in those with acute myocardial infarction. The human homologue, designated hsa-miR-Chr8:96, was identified in four independent cohorts of patients with myocarditis. The area under the receiver-operating-characteristic curve for this novel microRNA for distinguishing patients with acute myocarditis from those with myocardial infarction was 0.927 (95% confidence interval, 0.879 to 0.975). The microRNA retained its diagnostic value in models after adjustment for age, sex, ejection fraction, and serum troponin level. CONCLUSIONS: After identifying a novel microRNA in mice and humans with myocarditis, we found that the human homologue (hsa-miR-Chr8:96) could be used to distinguish patients with myocarditis from those with myocardial infarction.

RESUMO

BACKGROUND: Clonal hematopoiesis driven by somatic mutations in hematopoietic cells, frequently called clonal hematopoiesis of indeterminate potential (CHIP), has been associated with adverse cardiovascular outcomes in population-based studies and in patients with ischemic heart failure (HF) and reduced left ventricular ejection fraction (LVEF). Yet, the impact of CHIP on HF progression, including nonischemic etiology, is unknown. OBJECTIVES: The purpose of this study was to assess the clinical impact of clonal hematopoiesis on HF progression irrespective of its etiology. METHODS: The study cohort comprised 62 patients with HF and LVEF <45% (age 74 ± 7 years, 74% men, 52% nonischemic, and LVEF 30 ± 8%). Deep sequencing was used to detect CHIP mutations with a variant allelic fraction >2% in 54 genes. Patients were followed for at least 3.5 years for various adverse events including death, HF-related death, and HF hospitalization. RESULTS: CHIP mutations were detected in 24 (38.7%) patients, without significant differences in all-cause mortality (p = 0.151). After adjusting for risk factors, patients with mutations in either DNA methyltransferase 3 alpha (DNMT3A) or Tet methylcytosine dioxygenase 2 (TET2) exhibited accelerated HF progression in terms of death (hazard ratio [HR]: 2.79; 95% confidence interval [CI]: 1.31 to 5.92; p = 0.008), death or HF hospitalization (HR: 3.84; 95% CI: 1.84 to 8.04; p < 0.001) and HF-related death or HF hospitalization (HR: 4.41; 95% CI: 2.15 to 9.03; p < 0.001). In single gene-specific analyses, somatic mutations in DNMT3A or TET2 retained prognostic significance with regard to HF-related death or HF hospitalization (HR: 4.50; 95% CI: 2.07 to 9.74; p < 0.001, for DNMT3A mutations; HR: 3.18; 95% CI: 1.52 to 6.66; p = 0.002, for TET2 mutations). This association remained significant irrespective of ischemic/nonischemic etiology. CONCLUSIONS: Somatic mutations that drive clonal hematopoiesis are common among HF patients with reduced LVEF and are associated with accelerated HF progression regardless of etiology.

RESUMO

Purpose: The purpose of this study was to disclose the variability of pathways currently taken in the treatment of adolescent patients from diagnosis to final follow-up with a view to developing a more homogenous system. Patients & methods: A cross-sectional, observational and retrospective study of the cancer diagnosis and assignment to medical care teams in adolescent patients (12-20 years) from January 2008 to December 2018 was conducted. A total of 345 adolescent patients aged between 12 and 20 years, diagnosed with cancer and treated at Hospital Clinico Universitario Virgen de la Arrixaca were included. Results: CNS tumors, followed by leukemia were the most frequent tumors. At the time of diagnosis, the highest incidences of patients were assisted in the pediatrics service adult oncology service (21.7%) and hematology (11%). Conclusion: Our aim is to highlight the need for a better transition for patients from pediatric to adult oncology and hematology services.


Lay abstract This study shows the reality of the care of adolescent cancer patients in a hospital in southern Spain. A cross-sectional, observational and retrospective study of cancer diagnoses and assignment to medical care teams in adolescent patients (12­20 years) from January 2008 to December 2018 was conducted. A total of 345 adolescent patients between 12 and 20 years old who had a cancer diagnosis and were treated at Hospital Clinico Universitario Virgen de la Arrixaca were included. CNS tumors, followed by leukemia were the most frequent. At the time of diagnosis, the patients were most commonly attended by the pediatrics service, which concentrates 46.5% of the study population. There is great variability in the treatment and follow-up of the same tumors. The need for a better transition for patients from pediatric to adult oncology and hematology services is demonstrated.

RESUMO

BACKGROUND: Intravenous ferric carboxymaltose has been shown to improve symptoms and quality of life in patients with chronic heart failure and iron deficiency. We aimed to evaluate the effect of ferric carboxymaltose, compared with placebo, on outcomes in patients who were stabilised after an episode of acute heart failure. METHODS: AFFIRM-AHF was a multicentre, double-blind, randomised trial done at 121 sites in Europe, South America, and Singapore. Eligible patients were aged 18 years or older, were hospitalised for acute heart failure with concomitant iron deficiency (defined as ferritin <100 µg/L, or 100-299 µg/L with transferrin saturation <20%), and had a left ventricular ejection fraction of less than 50%. Before hospital discharge, participants were randomly assigned (1:1) to receive intravenous ferric carboxymaltose or placebo for up to 24 weeks, dosed according to the extent of iron deficiency. To maintain masking of patients and study personnel, treatments were administered in black syringes by personnel not involved in any study assessments. The primary outcome was a composite of total hospitalisations for heart failure and cardiovascular death up to 52 weeks after randomisation, analysed in all patients who received at least one dose of study treatment and had at least one post-randomisation data point. Secondary outcomes were the composite of total cardiovascular hospitalisations and cardiovascular death; cardiovascular death; total heart failure hospitalisations; time to first heart failure hospitalisation or cardiovascular death; and days lost due to heart failure hospitalisations or cardiovascular death, all evaluated up to 52 weeks after randomisation. Safety was assessed in all patients for whom study treatment was started. A pre-COVID-19 sensitivity analysis on the primary and secondary outcomes was prespecified. This study is registered with ClinicalTrials.gov, NCT02937454, and has now been completed. FINDINGS: Between March 21, 2017, and July 30, 2019, 1525 patients were screened, of whom 1132 patients were randomly assigned to study groups. Study treatment was started in 1110 patients, and 1108 (558 in the carboxymaltose group and 550 in the placebo group) had at least one post-randomisation value. 293 primary events (57·2 per 100 patient-years) occurred in the ferric carboxymaltose group and 372 (72·5 per 100 patient-years) occurred in the placebo group (rate ratio [RR] 0·79, 95% CI 0·62-1·01, p=0·059). 370 total cardiovascular hospitalisations and cardiovascular deaths occurred in the ferric carboxymaltose group and 451 occurred in the placebo group (RR 0·80, 95% CI 0·64-1·00, p=0·050). There was no difference in cardiovascular death between the two groups (77 [14%] of 558 in the ferric carboxymaltose group vs 78 [14%] in the placebo group; hazard ratio [HR] 0·96, 95% CI 0·70-1·32, p=0·81). 217 total heart failure hospitalisations occurred in the ferric carboxymaltose group and 294 occurred in the placebo group (RR 0·74; 95% CI 0·58-0·94, p=0·013). The composite of first heart failure hospitalisation or cardiovascular death occurred in 181 (32%) patients in the ferric carboxymaltose group and 209 (38%) in the placebo group (HR 0·80, 95% CI 0·66-0·98, p=0·030). Fewer days were lost due to heart failure hospitalisations and cardiovascular death for patients assigned to ferric carboxymaltose compared with placebo (369 days per 100 patient-years vs 548 days per 100 patient-years; RR 0·67, 95% CI 0·47-0·97, p=0·035). Serious adverse events occurred in 250 (45%) of 559 patients in the ferric carboxymaltose group and 282 (51%) of 551 patients in the placebo group. INTERPRETATION: In patients with iron deficiency, a left ventricular ejection fraction of less than 50%, and who were stabilised after an episode of acute heart failure, treatment with ferric carboxymaltose was safe and reduced the risk of heart failure hospitalisations, with no apparent effect on the risk of cardiovascular death.

RESUMO

OBJECTIVE: To design and validate a nursing screening procedure for diabetic peripheral neuropathy in primary care. METHODS: The study was carried out in three phases. 1)Construction of an item bank to form the procedure with an exit score describing the patient's clinical situation. 2)Test and reduction of the initial tentative procedure on a sample of 50 patients using community nurse consultations, eliminating the components with low inter-intra nurse reliability. 3)Validation of the version of the procedure obtained in the previous step on a sample of 106 patients. Calculation of validity and reliability by eliminating components with low criterion validity with respect to the results of the diagnostic electromyography used as a reference standard. Cut-off points were estimated for the use of the procedure as a screening tool, predictive values, performance, internal consistency and inter-nurse reliability. RESULTS: The initial tentative procedure consisted of 12 components that were reduced to 10. In the process of validation of this second version the procedure was simplified again, eventually comprising 6 components, with a cut-off point of 2.5 in its output scale, the point at which it reaches adequate values of sensitivity and negative predictors to be used as a screening instrument. For this cut-off point the inter-intra nurse reliability, criterion validity and predictive validity reached acceptable values. CONCLUSIONS: NeuDiaCan as a nursing screening procedure for diabetic peripheral neuropathy in primary care is valid, reliable and easy to use.

RESUMO

AIMS: Iron deficiency (ID) is a common co-morbidity in heart failure (HF), associated with impaired functional capacity, poor quality of life and increased morbidity and mortality. Treatment with intravenous (i.v.) ferric carboxymaltose (FCM) has shown improvements in functional capacity, symptoms and quality of life in stable HF patients with reduced ejection fraction. The effect of i.v. iron supplementation on morbidity and mortality in patients hospitalised for acute HF (AHF) and who have ID has yet to be established. The objective of the present article is to present the rationale and design of the AFFIRM-AHF trial (ClinicalTrials.gov NCT02937454) which will investigate the effect of i.v. FCM (vs. placebo) on recurrent HF hospitalisations and cardiovascular (CV) mortality in iron-deficient patients hospitalised for AHF. METHODS: AFFIRM-AHF is a multicentre, randomised (1:1), double-blind, placebo-controlled trial which recruited 1100 patients hospitalised for AHF and who had iron deficiency ID defined as serum ferritin <100 ng/mL or 100-299 ng/mL if transferrin saturation <20%. Eligible patients were randomised (1:1) to either i.v. FCM or placebo and received the first dose of study treatment just prior to discharge for the index hospitalisation. Patients will be followed for 52 weeks. The primary outcome is the composite of recurrent HF hospitalisations and CV mortality. The main secondary outcomes include the composite of recurrent CV hospitalisations and CV mortality, recurrent HF hospitalisations and safety-related outcomes. CONCLUSION: The AFFIRM-AHF trial will evaluate, compared to placebo, the effect of i.v. FCM on morbidity and mortality in iron-deficient patients hospitalised for AHF.

RESUMO

BACKGROUND: Antiplatelet therapy (APT) use in combination with oral anticoagulation is common among patients with atrial fibrillation, but there is scarce information regarding its effect on outcomes in patients on non-vitamin K antagonist oral anticoagulants (NOAC). We aimed to evaluate the safety and efficacy of APT use in a 'real-world' cohort of nonvalvular atrial fibrillation (NVAF) patients initiating NOAC. DESIGN: We conducted a retrospective multicentre study including 2361 consecutive NVAF patients initiating NOAC between January 2013 and December 2016. Patients with an acute ischaemic event within the last 12 months (acute coronary syndrome, stroke or revascularization) were excluded. Patients were followed up, and all clinical events were recorded at 3 months. The primary outcome of the study was major bleeding, and the secondary outcomes were stroke, nonfatal myocardial infarction, intracranial bleeding and death. RESULTS: One hundred forty-five (6.1%) patients received concomitant APT, and aspirin was the more common (79%). At 3 months, 25 (1.1%) patients had major bleeding, 8 (0.3%) had nonfatal myocardial infarction, 7 (0.3%) had ischaemic stroke, and 40 (1.7%) died. After multivariate adjustment, concomitant APT was associated with higher risk for major bleeding (HR = 3.62, 95% CI 1.32-9.89; P = .012), but was not associated with a higher risk of other clinical outcomes. CONCLUSIONS: Concomitant APT use is uncommon among these patients and does not seem to be associated with lower rates of ischaemic events or death. However, there are signals for an increased risk of bleeding, which reinforces current guideline recommendations.

RESUMO

BACKGROUND: Cancer therapy-induced cardiomyopathy (CCM) is associated with cumulative drug exposures and preexisting cardiovascular disorders. These parameters incompletely account for substantial interindividual susceptibility to CCM. We hypothesized that rare variants in cardiomyopathy genes contribute to CCM. METHODS: We studied 213 patients with CCM from 3 cohorts: retrospectively recruited adults with diverse cancers (n=99), prospectively phenotyped adults with breast cancer (n=73), and prospectively phenotyped children with acute myeloid leukemia (n=41). Cardiomyopathy genes, including 9 prespecified genes, were sequenced. The prevalence of rare variants was compared between CCM cohorts and The Cancer Genome Atlas participants (n=2053), healthy volunteers (n=445), and an ancestry-matched reference population. Clinical characteristics and outcomes were assessed and stratified by genotypes. A prevalent CCM genotype was modeled in anthracycline-treated mice. RESULTS: CCM was diagnosed 0.4 to 9 years after chemotherapy; 90% of these patients received anthracyclines. Adult patients with CCM had cardiovascular risk factors similar to the US population. Among 9 prioritized genes, patients with CCM had more rare protein-altering variants than comparative cohorts ( P≤1.98e-04). Titin-truncating variants (TTNtvs) predominated, occurring in 7.5% of patients with CCM versus 1.1% of The Cancer Genome Atlas participants ( P=7.36e-08), 0.7% of healthy volunteers ( P=3.42e-06), and 0.6% of the reference population ( P=5.87e-14). Adult patients who had CCM with TTNtvs experienced more heart failure and atrial fibrillation ( P=0.003) and impaired myocardial recovery ( P=0.03) than those without. Consistent with human data, anthracycline-treated TTNtv mice and isolated TTNtv cardiomyocytes showed sustained contractile dysfunction unlike wild-type ( P=0.0004 and P<0.002, respectively). CONCLUSIONS: Unrecognized rare variants in cardiomyopathy-associated genes, particularly TTNtvs, increased the risk for CCM in children and adults, and adverse cardiac events in adults. Genotype, along with cumulative chemotherapy dosage and traditional cardiovascular risk factors, improves the identification of patients who have cancer at highest risk for CCM.

RESUMO

BACKGROUND: Myocardial uptake of bone tracers has emerged as useful tool for the early detection of transthyretin amyloidosis (ATTR). The prevalence of wild-type ATTR (ATTRwt) in individuals remains to be established. METHODS: All whole body bone scans performed in individuals ≥ 75 years with no previous clinical suspicion of ATTR were revised in a population-based university hospital over a 7-year period (1509 studies corresponding to 1114 patients; 80.5 ±â€¯4.1 years, 65% males). Positive cardiac uptake was defined according to Perugini score as grade 2 or 3. Heart failure (HF) hospitalizations during the follow-up were obtained from regional administrative databases. RESULTS: Thirty-one patients ≥ 75 years (2.78%) showed cardiac uptake; compared with those without uptake, these patients were older (85 ±â€¯5 vs. 80 ±â€¯4, p < 0.001) and predominantly males (90% vs. 64%, p = 0.005). The prevalence of cardiac uptake was 3.88% in males and 0.77% in females, and increased with age, reaching 13.9% in males≥85 years (2.7% among females). The estimated prevalence for the European standard population ≥ 75 years was 4.15% in males, 1.03% in females and 2.59% in the general population. HF hospitalizations rates were 14% in patients without uptake and 29% in those with cardiac uptake (p = 0.034). After adjusting for age and gender, cardiac uptake was associated with a higher risk of HF hospitalization (OR 2.60, 95%CI 1.09-5.74, p = 0.022). CONCLUSIONS: Myocardial uptake in bone scan is very prevalent with ageing, mainly affects males and is associated with an increased risk of HF hospitalization. These findings reinforce ATTRwt as a relevant cause of HF in the elderly.

RESUMO

Although the initial reparative fibrosis after myocardial infarction (MI) is crucial for preventing rupture of the ventricular wall, an exaggerated fibrotic response and reactive fibrosis outside the injured area are detrimental. Although metformin prevents adverse cardiac remodeling, as well as provides glycemic control, the underlying mechanisms remain poorly documented. This study describes the effect of mitochondrial NADPH oxidase 4 (mitoNox) and protein kinase C-alpha (PKCα) on the cardiac fibrosis and galectin 3 (Gal-3) expression. Randomly rats underwent MI, received metformin or saline solution. A model of biomechanical strain and co-culturewas used to enable cross talk between cardiomyocytes and fibroblasts. Long-term metformin treatment after MIwas associated with (1) a reduction in myocardial fibrosis and Gal-3 levels; (2) an increase in adenosine monophosphate-activated protein kinase (AMPK) α1/α2 levels; and (3) an inhibition of both mRNA expression and enzymatic activities of mitoNox and PKCα. These findings were replicated in the cellular model, where the silencing of AMPK expression blocked the ability of metformin to protect cardiomyocytes from strain. The use of specific inhibitors or small interference RNA provided evidence that PKCα is downstream of mitoNox, and that the activation of this pathway results in Gal-3 upregulation.The Gal-3 secreted by cardiomyocytes has a paracrine effect on cardiac fibroblasts, inducing their activation. In conclusion, a metformin-induced increase in AMPK improves myocardial remodeling post-MI, which is related to the inhibition of the mitoNox/PKCα/Gal-3 pathway. Manipulation of this pathway might offer new therapeutic options against adverse cardiac remodeling, in terms of preventing the activation of the present fibroblast population.

RESUMO

Aims: Short QT syndrome (SQTS) is a rare cardiac channelopathy characterized by a shortened corrected QT (QTc)-interval that can lead to ventricular arrhythmias and sudden cardiac death. The aim of this study was to investigate the clinical phenotypes and long-term outcomes of three families harbouring genetic mutations associated with the SQTS. Methods and results: Clinical data included medical history, physical examination, 12-lead ECG, 24-h Holter-ECG, and transthoracic echocardiography from three index patients and their first-degree relatives. Next generation clinical exome sequencing and genetic cascade screening were performed in index patients and their relatives, respectively. Two index patients experienced malignant ventricular arrhythmias and one patient suffered from arrhythmogenic syncope during a median follow-up period of 8 years. They all had genetic mutations associated with the SQTS. Two mutations were found in the KCNH2 gene, and one in the CACNA2D gene. One patient had an additional SCN10A variant. Alive and mutation-positive family members had short QTc-intervals, but no further phenotypic manifestations. None of the mutation-negative family members had an abnormal ECG or any symptoms. In all patients with shortened QTc-intervals, the QTc-interval had a low long-term variability and QTc shortening always remained detectable by 12-lead ECG. Conclusion: This study shows the variety of phenotypic manifestations in different families with SQTS. It further emphasizes the importance of a 12-lead ECG for early diagnosis, and the utility of next generation sequencing for the identification of mutations associated with the SQTS.

RESUMO

Resumen ANTECEDENTES: El estruma ovárico es una variedad infrecuente de teratoma quístico. CASO CLÍNICO: Paciente de 42 años de edad en quien durante una revisión ginecológica rutinaria se evidenció, por ecografía, un quiste anexial derecho complejo, bilobulado, de 10 cm compuesto por dos formaciones heterogéneas independientes, una de aspecto uniforme ecorrefringente de 52.6 mm y otra ecorrefringencia alternante de 36.7 mm. Se categorizó como teratoma quístico, lo que se confirmó por resonancia magnética nuclear. Se efectuó anexectomía derecha laparoscópica. El estudio anatomopatológico confirmó el diagnóstico microscópico de teratoma quístico maduro, que incluía a la tiroides (menos de 50% de todo el tumor), con un carcinoma papilar de patrón folicular (estruma ovárico). La cirugía ginecológica se complementó con histerectomía total, omentectomía, lavado peritoneal e inspección de la cavidad abdominal por vía laparotómica; se descartó la neoplasia residual. El estudio endocrinológico evidenció la normalidad de la tiroides y el diagnóstico ecográfico de un nódulo; posteriormente se confirmó que se trataba de hiperplasia benigna. Los marcadores tumorales tiroideos fueron negativos y, a pesar de ello, el comité de cáncer de tiroides acordó que se efectuara la tiroidectomía total y luego se indicara tratamiento con iodo radiactivo, sin evidenciar elementos neoplásicos malignos ni ganglios linfáticos afectados. CONCLUSIONES: Debido a la baja incidencia del estruma ovárico su tratamiento comprende a la cirugía ovárica y la tiroidectomía, y al yodo radioactivo en el caso de las variedades malignas; todo esto en un contexto de controversia consecuencia de la poca experiencia acumulada.


Abstract BACKGROUND: Struma ovarii represents a rare form of ovarial quistic teratom that contains thiroid tissue and affects mostly women between 40 and 60 years of age. Its diagnosis is based on the definitive pathological study of the piece, due to the fact that these kind of tumors lack any specific clinic and diagnostic features. CLINICAL CASE: 42 year old patient, in which during a routine gynecological examination a bilobed complex right adnexal cyst of 10 cm composed of two independent heterogeneous formations (a uniform appearance ecorrefringente of 52.6mm and one alternate ecorrefrigencia of 36.7 mm) is evidenced by ultrasound. It is categorized as cystic teratoma and confirmed by nuclear magnetic resonance. Adnexectomy is performed laparoscopically. The pathological study confirmed the microscopic diagnosis of mature cystic teratoma including thyroid tissue (less than 50% of the tumor) with papillary carcinoma follicular pattern: Struma Ovarii. Gynecological surgery was completed with a total hysterectomy, omentectomy, washing and inspection peritoneal abdominal cavity by laparotomy discarding residual neoplasia. Endocrinological study showed normal thyroid function and ultrasound diagnosis of a nodule: benign hyperplasia was confirmed later. Thyroid tumor markers were negative and despite this, the thyroid cancer committee agreed to perform a total thyroidectomy and a treatment with radioiodine, without evidence of malignant neoplastic elements and affected lymph nodes. CONCLUSIONS: Its treatment is still controversial due to its low incidence, and includes not only ovarial surgery but also thyroidectomy and radioactive iodine therapy in the event of a malignant tumor.

RESUMO

Sprague Dawley rats were subjected to acute myocardial infarction (AMI) by permanent ligation of the left anterior descending coronary artery. At the time of AMI, a subcutaneous mini-osmotic pump was implanted and animals were randomized into three groups, according to the intravenous therapy received during the first 72 h: placebo-treated (saline), serelaxin10-treated (SRLX10 = 10 µg/kg/day), or serelaxin30-treated (SRLX30 = 30 µg/kg/day). Treatment with SRLX30 reduced the expression of inflammatory cytokines and chemokines, as well as the infiltration of macrophages, and increased the expression of pro-angiogenic markers and vessel density in the infarcted myocardium after 7 days. SRLX30 did not reduce early myocardial fibrosis but reduced myocardial levels of sST2 and galectin-3. No significant effects were observed with SRLX10 treatment. A significant correlation was observed between plasma levels of serelaxin and effect measures. The results suggest serelaxin has a protective effect in early processes of cardiac remodeling after AMI.
