RESUMEN

In Mozambique, cervical cancer is the most frequent cancer in women. However, studies about cervical cancer treatment and prognosis are scarce. We describe the clinical characteristics, treatment and survival of patients with cervical cancer admitted to Maputo Central Hospital (MCH) in 2016 to 2018. Sociodemographic, clinical and cancer-related data were retrieved from clinical records of patients admitted to the Oncology Service of the MCH with an incident cervical cancer in 2016 to 2018 (n = 407). The Pathology Service database was used to obtain information regarding pathological diagnosis. Survival data was obtained through the MCH Cancer Registry and clinical records. Odds ratios for the association between patients' characteristics and the diagnosis of advanced stage cancer were computed using logistic regression. Survival analyses were performed using the Kaplan-Meier estimator. A total of 91.2% of the patients were diagnosed with advanced disease (stage IIB-IV) and squamous cell carcinoma was the predominant histological subtype. Most of the patients underwent chemotherapy (93.1%) but <7% were submitted to surgery, radiotherapy or brachytherapy. Those living with HIV had 3.4-fold higher odds of advanced disease. Overall survival was 72.7% (95% confidence interval [CI]: 67.9-77.0) at 1-year and 51.0% (95%CI: 45.3-56.3) at 2-years. Those with early stage (IA-IIA) and asymptomatic at diagnosis had a significantly higher 2-year overall survival. In Mozambique, cervical cancer is diagnosed mostly in advanced stages, resulting in poor prognosis. This highlights the importance of HPV vaccination and screening, to decrease the burden of cervical cancer in this context.

RESUMEN

PURPOSE: We aimed to assess the impact of surgery of primary tumor in overall survival (OS) of women with de novo metastatic breast cancer. METHODS: Nationwide, population-based retrospective cohort study of women diagnosed with de novo metastatic breast cancer in Belgium, between Jan/2010-Dec/2014. Data was obtained from the Belgian Cancer Registry and administrative databases. "Surgery" group was defined by surgery of primary tumor up to nine months after diagnosis. We excluded women who did not receive systemic treatment or did not complete nine months follow-up after diagnosis. All the subsequent analyses reporting on overall survival and the stratified outcome analyses were performed based on this nine-month landmark cohort. OS was estimated using Kaplan-Meier method and compared using adjusted Cox proportional hazards models controlling for confounders with 95% confidence intervals (CI). We performed a stratified analysis according to surgery timing and a propensity score matching analysis. RESULTS: 1985 patients, 534 (26.9%) in the "Surgery" and 1451 (73.1%) in the "No Surgery" group. Patients undergoing surgery were younger (p < 0.001), had better performance status (PS) (p < 0.001), and higher proportion of HER2-positive and triple-negative breast cancer (p = 0.012). Median follow-up was 86.0 months (82.6-88.5). Median OS was 60.1 months (57.1-68.2) in the "Surgery" vs. 41.9 months (39.8-44.2) in the "No Surgery" group (adjusted HR 0.56; 0.49-0.64). OS was similar when surgery was performed upfront or after systemic treatment. Propensity score matching analysis confirmed the same findings. CONCLUSION: Among patients receiving systemic treatment for de novo metastatic breast cancer and surviving nine months or more, those who received surgery of the primary tumor within nine months of diagnosis have longer subsequent survival than those who did not.

RESUMEN

OBJECTIVES: Cardiovascular disease worsens the prognosis of rheumatoid arthritis (RA) and vice-versa. Inflammation may be a common pathway for both conditions. It is expected that a longer RA duration leads to a greater inflammatory cumulative exposure burden; however, studies on the association between RA disease duration and outcomes are scarce. Our aim is to compare the characteristics, biomarker expression and outcomes according to the duration of RA. METHODS: Prospective cohort study including 399 RA patients, with detailed clinical, echocardiographic, and proteomic phenotyping that were compared across tertiles of RA disease duration. Cox proportional models were used to study the association of disease duration with cardiovascular outcomes. RESULTS: RA duration tertiles were: tertile 1 with median of 3.2; tertile 2 with median of 8.8; and tertile 3 with median of 21.8 years. Compared to tertile 1, patients in tertile 3 were older, had more erosive disease, more frequent echocardiographic alterations, lower haemoglobin and walked a shorter distance on the 6MWT. Natriuretic peptides, cathepsin L1, galectin 9, matrix metalloproteinase-12, adrenomedullin and tumour necrosis factor receptor 11A were higher in patients with longer disease duration. Compared to patients in tertile 1, those in tertile 3 had higher risk of a subsequent cardiovascular hospitalisation or cardiovascular death (HR 2.71, 95%CI 1.06-6.92, p=0.04). CONCLUSIONS: RA patients with longer disease duration had more organ damage and worse outcomes than those with shorter disease duration. Biomarker expression suggested that patients with longer RA duration had activation of pathways related to inflammation, extracellular matrix organisation, fibrosis and congestion.

RESUMEN

Introduction: Pregnancy in patients with autoimmune disorders is associated with an increased risk of adverse outcomes. Sjögren's syndrome (SS) is one of the most common among autoimmune diseases. Presently data regarding the impact of SS on obstetric outcomes are scarce and inconclusive. This study aims to evaluate the impact of SS on maternal-fetal and neonatal outcomes compared with pregnancy outcomes in the general population. Material and methods: A retrospective case-control study included 26 pregnancies in SS patients and a healthy control group (CG), followed in a Portuguese tertiary center, between 2015 and 2020. Baseline maternal data were collected, and maternal-fetal and neonatal outcomes were evaluated. Statistical analysis used SPSS 25.0, and a p-value of 0.05 was considered statistically significant. Results: All pregnancies occurred after the diagnosis of SS, with a mean exposure time between diagnosis and pregnancy of 4.92 ±2.78 years. In the SS group, the incidence of ANA, anti-Ro/SSA, and anti-La/SSB antibodies positivity was 80.8%, 61.5%, and 46.2%, respectively. Hydroxychloroquine (HCQ) was used in 57.7%.Miscarriage was significantly higher in the SS group (19.2% vs. 1.8%, p < 0.01). There was a higher prevalence of fetal growth restriction (OR 11.16, 95% CI: 0.96-129.26). Preterm delivery (9.5% vs. 5.6%, p = 0.503) and mean birth weight (2998.16 g vs. 3155.79 g, p = 0.178) did not differ significantly between the groups. In the SS group, admission to the neonatal intensive care unit (NICU) rate was increased (OR 71.67, 95% CI: 3.78-1357.16). Three pregnancies were complicated by congenital heart block (CHB) (14.3% vs. 0%, p = 0.015). In all cases, the diagnosis was performed during second trimester of pregnancy, and betamethasone was administered. Conclusions: Women with SS had a significantly higher incidence of miscarriage, admission to NICU, and CHB than controls. Congenital heart block was the most critical condition that affects the offspring of mothers with SS. Successful pregnancy in the study group was possible with prenatal monitoring and a multidisciplinary approach.

RESUMEN

BACKGROUND: Despite the international endorsement of multidisciplinary tumor boards (MTBs) for breast cancer care, implementation is suboptimal worldwide, and evidence regarding their effectiveness in developing countries is lacking. We assessed the impact on survival and the cost-effectiveness of implementing an MTB in Mozambique, sub-Saharan Africa. MATERIALS AND METHODS: This prospective cohort study included 205 patients with breast cancer diagnosed between January 2015 and August 2017 (98 before and 107 after MTB implementation), followed to November 2019. Pre- and post-MTB implementation subcohorts were compared for clinical characteristics, treatments, and overall survival. We used hazard ratios and 95% confidence intervals (CI), computed by Cox proportional hazards regression. The impact of MTB implementation on the cost per quality-adjusted life year (QALY) was estimated from the provider perspective. RESULTS: We found no significant differences between pre- and post-MTB subcohorts regarding clinical characteristics or treatments received. Among patients with early breast cancer (stage 0-III; n = 163), the 3-year overall survival was 48.0% (95% CI, 35.9-59.1) in the pre-MTB and 73.0% (95% CI, 61.3-81.6) in the post-MTB subcohort; adjusted hazard ratio, 0.47 (95% CI, 0.27-0.81). The absolute 3-year mean cost increase was $119.83 per patient, and the incremental cost-effectiveness ratio was $802.96 per QALY, corresponding to 1.6 times the gross domestic product of Mozambique. CONCLUSION: The implementation of a MTB in Mozambique led to a 53% mortality decrease among patients with early breast cancer, and it was cost-effective. These findings highlight the feasibility of implementing this strategy and the need for scaling-up MTBs in developing countries, as a way to improve patient outcomes. IMPLICATIONS FOR PRACTICE: Currently, more than half of the deaths from breast cancer in the world occur in developing countries. Strategies that optimize care and that are adjusted for available resources are needed to improve the outcomes of patients with breast cancer in these regions. The discussion of cases at multidisciplinary tumor boards (MTBs) may improve survival outcomes, but implementation is suboptimal worldwide, and evidence regarding their effectiveness in developing countries is lacking. This study evaluated the impact of implementing an MTB on the care and survival of patients with breast cancer in Mozambique, sub-Saharan Africa and its cost-effectiveness in this low-income setting.

RESUMEN

Ovarian cancer (OC) represents the most lethal gynaecological neoplasia. Conversely, venous thromboembolism (VTE) and OC are intricately connected, with many haemostatic components favouring OC progression. In light of this bilateral relationship, genome-wide association studies (GWAS) have reported several single-nucleotide polymorphisms (SNPs) associated with VTE risk that could be used as predictors of OC clinical outcome for better therapeutic management strategies. Thus, the present study aimed to analyse the impact of VTE GWAS-identified SNPs on the clinical outcome of 336 epithelial ovarian cancer (EOC) patients. Polymorphism genotyping was performed using the TaqMan® Allelic Discrimination methodology. Carriers with the ZFPM2 rs4734879 G allele presented a significantly higher 5-year OS, 10-year OS and disease-free survival (DFS) compared to AA genotype patients with FIGO I/II stages (P = 0.009, P = 0.001 and P = 0.003, respectively). Regarding SLC19A2 rs2038024 polymorphism, carriers with the CC genotype presented a significantly lower 5-year OS, 10-year OS and DFS compared to A allele carriers in the same FIGO subgroup (P < 0.001, P = 0.004 and P = 0.005, respectively). As for CNTN6 rs6764623 polymorphism, carriers with the CC genotype presented a significantly lower 5-year OS compared to A allele carriers with FIGO I/II stages (P = 0.015). As for OTUD7A rs7164569, F11 rs4253417 and PROCR rs10747514, no significant impact on EOC patients' survival was observed. However, future studies are required to validate these results and uncover the biological mechanisms underlying our results.

RESUMEN

BACKGROUND: We aimed to identify and characterize quality of life trajectories up to 3 years after breast cancer diagnosis. METHODS: A total of 460 patients were evaluated at baseline (before treatments), and after 1- and 3-years. Patient-reported outcomes, including quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30, QLQ-C30), anxiety, depression and sleep quality, were assessed in all evaluations. Model-based clustering was used to identify quality of life trajectories. RESULTS: We identified four trajectories without intersection during 3 years. The two trajectories characterized by better quality of life depicted relatively stable scores; in the other trajectories, quality of life worsened until 1 year, though in one of them the score at 3 years improved. Sociodemographic and clinical characteristics at baseline did not differ between trajectories, except for mastectomy, which was higher in the worst trajectory. Anxiety, depression and poor sleep quality increased from the best to the worst trajectory. CONCLUSIONS: The type of surgery and the variation of other patient-reported outcomes were associated with the course of quality of life over 3 years. More research to understand the heterogeneity of individual trajectories within these major patterns of variation is needed.

RESUMEN

PURPOSE: Body composition parameters including muscle and adipose tissue measurements have emerged as prognostic factors in cancer patients. Besides cell cycle regulation, CDK 4 and 6 also control metabolic processes (lipid synthesis, glycolysis, and mitochondrial function). We studied the impact of baseline body composition parameters on response to CDK 4/6 inhibition and changes on body composition during treatment. METHODS: Retrospective study of 50 patients treated at Institut Jules Bordet between December 2016 and August 2019 with endocrine therapy and CDK 4/6 inhibitor as first or second-line treatment for metastatic breast cancer (BC). CT-based body composition analysis was performed at 3 time points. Cox regression and Kaplan-Meier method were used for the association with Progression-free survival (PFS). Changes in body composition parameters were described in means and compared using paired sampled T test. RESULTS: Baseline sarcopenia was present in 40% of patients and associated with a significantly worse PFS compared to patients without sarcopenia (20.8 vs 9.6 months, HR 2.52; 95% CI 1.02-6.19, p = 0.037). Patients with higher visceral fat index and higher visceral fat density had better PFS (20.8 vs 10.4 months, HR 0.40; 95% CI 0.16-0.99 p = 0.041-stratified for treatment line). No significant alterations in body composition parameters during treatment were observed. CONCLUSION: Sarcopenia is a potential early marker of poor prognosis among patients with metastatic BC treated with CDK 4/6 inhibitors. CT scan evaluation of sarcopenia and adiposity revealed significant prognostic information. Visceral fat could also play an important role in response to CDK 4/6 inhibitors, deserving further investigation.

RESUMEN

The identification of predictive biomarkers for the first-line treatment of epithelial ovarian cancer (EOC) remains a challenge. Although genome-wide association studies (GWAS) have identified several genetic polymorphisms as predictors of EOC clinical outcome, the subsequent validation has not yet been performed. This study aims to validate the influence of Neuregulin 3 (NRG3) rs1649942 and Brain and reproductive organ-expressed (TNFRSF1A modulator) (BRE) rs7572644 GWAS-identified variants in an independent cohort of EOC patients from the North region of Portugal (n = 339) submitted to first-line treatment. Polymorphism genotypes were determined by real-time PCR using validated assays. Patients carrying the NRG3 rs1649942 A allele presented a significantly longer overall survival (OS) when compared to GG-genotype patients (log-rank test, P = 0.011) in the FIGO IV stage subgroup. No impact was observed for early-stage patients or considering disease-free survival (DFS) as an outcome. For FIGO I/II stage patients, BRE rs7572644 C allele carriers exhibit a decreased OS (P = 0.014) and DFS (P = 0.032) when compared to TT-homozygous patients. Furthermore, a Multivariate Cox regression analysis revealed a three-fold increase in the risk of death (HR, 3.09; P = 0.015) and recurrence (HR, 3.33; P = 0.009) for FIGO I/II C allele carriers. No significant impact was observed for late-stage patients. The BRE rs7572644 and NRG3 rs1649942 genetic variants were validated in an independent cohort of EOC Portuguese patients, particularly in specific subgroups considering FIGO staging. Further functional post-GWAS analyses are indispensable to understand the biological mechanisms underlying the observed results.

RESUMEN

Background: Endoscopic mucosal resection (EMR) is the first-line approach to large colorectal sessile lesions. These patients have been associated with high rates of metachronous lesions (ML), but long-term follow-up (LtFU) data are lacking. We aimed at evaluating the efficacy of an LtFU protocol and analyse the development and risk factors for ML.Methods: A prospectively collected database was analysed. Seventy-six patients submitted to EMR of large colorectal sessile lesions between 2007 and 2013 complied with a specific endoscopic surveillance, consisting of two protocols - initial follow-up (iFU) and LtFU. iFU intended to inspect the mucosectomy scars twice (at 3-6 and 12 months) and remove synchronous lesions (SL). Protocol examinations of LtFU were carried out at the first- and fourth-year post-iFU, aiming to remove ML. Statistical analysis included variables related to patient, index lesion, SL and ML characteristics.Results: Rates of ML were 39.5% and 20.4% at the first- and fourth-year of LtFU, and respectively 11.8% and 3.7% of them were advanced ML. All ML were endoscopically resectable. At univariate analysis, male gender (OR: 2.91; p=.029), the presence of SL (OR 3.86, p=.010) and advanced SL (OR 4.25, p=.006) were risk factors for ML. At multivariate analysis, male gender (p=.031) and advanced SL (p=.006) were significant predictors of ML development.Conclusions: We confirmed the increased risk of ML in patients with large colorectal lesions. A significant number of advanced ML was removed at the first LtFU colonoscopy, probably it should be carried out earlier than currently recommended.

RESUMEN

The number of breast cancer (BC) cases is growing worldwide, being most frequently diagnosed in the early-setting. Mammaprint™ is a 70-gene-expression signature, originally designed for selecting early BC patients with low risk of developing metastasis, so that they could be spared adjuvant chemotherapy. Its use as a prognostic biomarker has been extensively validated, both retrospectively and prospectively. However, its value as a predictive tool and as a clinically useful tool remains controversial. This review will describe how the test works, its application in the clinic and its limitations. Cost-effectiveness studies will be summarized. Finally, we will provide a perspective on the use of Mammaprint in the near future, as a valuable tool for personalizing the treatment of early BC patients.

RESUMEN

Delays in detection, diagnosis and treatment may lead to poorer prognosis in women with breast cancer. We quantified time intervals from first detection (FD) to diagnosis (D) and first treatment (FT) and identified associated factors. We studied 282 patients diagnosed with breast cancer during 2012 at the Breast Clinic of the Portuguese Institute of Oncology in Porto, Portugal using face-to-face interview and medical records. Associations of sociodemographic and clinical characteristics with time intervals was computed using adjusted percentage differences (adjPD) after logarithmic transformation, odds ratios (adjOR) for comparing the highest and lowest thirds of the distribution and 95 percent confidence intervals (CI) for both measures, using linear and logistic regression, respectively. The median times between FD and D and FT were 31 and 44 days, respectively. Significantly longer periods between FD and D were found in symptomatic women (adjPD = 99.5, 95 percent CI: 37.1, 190.0; adjOR = 3.16, 95 percent CI: 1.57, 6.33). More advanced stage was associated with shorter intervals between D and FT (adjPD = -33.8, 95 percent CI: -44.2, -21.5; adjOR = 0.14, 95 percent CI: 0.05, 0.34). Although some differences according to clinical characteristics were observed, they did not seem to translate into inequities in access to public healthcare in this group of women.

RESUMEN

Many conditions interfere with butyrylcholinesterase (BChE) activity, e.g., pregnancy or presence of the BCHE gene variant -116A can decrease activity whereas obesity and types I and II diabetes mellitus can increase activity. In this study, we examined BChE activity, -116A and 1615A BCHE gene variants, and anthropometric and biochemical variables associated with diabetes in patients with gestational diabetes mellitus (GDM) and in healthy pregnant women. BChE activity was measured spectrophotometrically using propionylthiocholine as substrate and genotyping of the -116 and 1615 sites of the BCHE gene was done with a TaqMan SNP genotyping assay. Three groups were studied: 150 patients with GDM, 295 healthy pregnant women and 156 non-pregnant healthy women. Mean BChE activity was significantly lower in healthy pregnant women than in women from the general population and was further reduced in GDM patients. BChE activity was significantly reduced in carriers of -116A in GDM patients and healthy pregnant women. Although GDM patients had a significantly higher mean body mass index (BMI) and triglycerides than healthy pregnant women, they had lower mean BChE activity, suggesting that the lowering effect of GDM on BChE activity was stronger than the characteristic enhancing effect of increased BMI and triglycerides.

RESUMEN

Right ventricle-pulmonary artery (RV-PA) coupling has been linked to clinical outcomes in patients with severe aortic stenosis (AS) undergoing transcatheter valve implantation (TAVI). However, the best timing for prognostic assessment remains uncertain. Our aim was to determine the impact of RV longitudinal function parameters and RV-PA coupling on mortality in patients undergoing TAVI.  Retrospective, single center, analysis including patients with AS who underwent TAVI between 2007 and 2021. Echocardiographic evaluation was performed before, shortly after the procedure, and during follow-up. RV-PA uncoupling was defined as a TAPSE/PASP ratio<0.55 (severe RV uncoupling was defined as TAPSE/PASP ratio<0.32. The effect of RV parameters on all-cause mortality up to 12 months was assessed.  Among the 577 patients included, pre-procedural TAPSE/PASP ratio data were available for 205. RV-PA uncoupling was present in 113 patients (55.1%), with severe uncoupling observed in 31 (15.1%). Within the first 12 months after TAVI, 51 patients (9%) died. Severe RV-PA uncoupling was associated with mortality in univariable Cox regression; however, this association was lost after adjusting for EuroSCORE II. A significant association was found between the TAPSE/PASP ratio (per 0.1-unit increase) after the procedure and the primary endpoint (HR: 0.73; 95% CI: 0.56, 0.97; p=0.029). Higher postprocedural PASP (HR: 1.04; 95% CI: 1.02, 1.06; p<0.001 was also associated with all-cause mortality.  V-PA uncoupling and PASP after TAVI are associated with all-cause mortality in patients and may be valuable for patient selection and for planning post-procedural care.

RESUMEN

AIMS: Acute myocardial infarction (AMI) resulting from unprotected left main coronary artery (LMCA) occlusion and subtotal occlusion is a life-threatening condition. Although AMI management has improved in the past two decades, there is limited information on recent trends in patient characteristics, management, and outcomes for acute unprotected LMCA-related AMI. This study aims to assess such trends over a 12 year period. METHODS AND RESULTS: This retrospective multicentre study includes patients with unprotected LMCA occlusion/subtotal occlusion admitted to three tertiary hospitals between 2008 and 2020. The patients were divided into two groups based on the chronology of presentation: a 'past group' (January 2008 to December 2014) and a 'contemporary group' (January 2015 to December 2020). The study compares clinical characteristics, management approaches, and outcomes between the two groups. The study includes 128 patients, with 51 (40%) in the 'past group' and 77 (60%) in the 'contemporary group'. Baseline risk factors did not show statistically significant differences between the two groups, except for hypertension (49% vs. 74%; P = 0.005). Chest pain was more frequent in the 'past group' (98% vs. 89%; P = 0.014), and a trend towards more cardiac arrests was observed in the 'contemporary group' (18% vs. 31%; P = 0.087). Revascularization type did not differ significantly (P = 0.419), but manual thrombectomy was less frequently used (41% vs. 23%; P = 0.032) and stent implantation showed a trend towards higher rates (66% vs. 78%; P = 0.150) in the 'contemporary cohort'. There was a gradual shift from bare-metal to drug-eluting stents, with a significantly higher percentage of ticagrelor/prasugrel loading in the 'contemporary cohort' (5% vs. 79%; P < 0.001). The use of mechanical circulatory support (MCS), although not statistically significant, was higher among patients in the 'past group' (67% vs. 51%; P = 0.073). The type of MCS differed significantly between groups, with a decrease in intra-aortic balloon pump use (67% vs. 42%; P = 0.005) and an increase in veno-arterial extracorporeal membrane oxygenation (4% vs. 22%; P = 0.005) and Impella system (0% vs. 3%) over time. Survival analysis showed no significant differences (P = 0.599; log-rank test) in all-cause mortality between the different time groups, with the long-term survival rate being approximately 30%. CONCLUSIONS: In our real-world population, despite the progressive use of newer drugs and more advanced devices over time, patients with unprotected LMCA occlusion/subtotal occlusion remain a subpopulation with poor prognosis.

RESUMEN

OBJECTIVE: To evaluate the role of adding grandparents' data to parental information to the assessment of a family history of diabetes, in order to identify adolescents with high fasting glucose. METHOD: In 2003 we evaluated 1276 population-based 13-year-olds, from Porto, Portugal. The history of diabetes in parents and grandparents was collected using self-reported questionnaires and a clinical evaluation was performed, including a fasting blood sample. The 75th percentile of fasting plasma glucose (FPG=91 mg/dl) was used to create two groups of participants (high vs. low fasting glucose). RESULTS: No association was found between family history of diabetes (with or without grandparental data) and a high FPG. The sensitivity to identify individuals with high FPG increased from 7.8% to 47.9% when grandparental history was combined with parental data. The positive predictive value was slightly increased (25.2% vs. 27.8%) but the specificity dropped (91.8% vs. 56.4%). CONCLUSION: Combining parental with grandparental history increased the number of adolescents with a positive family history of diabetes and also increased the sensitivity to identify adolescents with high FPG. So, even if it determines a decrease in specificity, grandparental data is relevant when screening for high fasting glucose in adolescents.

RESUMEN

Desmoplakin (DSP) is a desmosomal protein that plays an essential role for cell-to-cell adhesion within the cardiomyocytes. The first association between DSP genetic variants and the presence of a myocardial disease referred to patients with Carvajal syndrome. Since then, several reports have linked the DSP gene to familial forms of arrhythmogenic (ACM) and dilated cardiomyopathies. Left-dominant ACM is the most common phenotype in individuals carrying DSP variants. More recently, a new entity-"Desmoplakin cardiomyopathy"-was described as a distinct form of cardiomyopathy characterized by frequent left ventricular involvement with extensive fibrosis, high arrhythmic risk, and episodes of acute myocardial injury. The purpose of this review was to summarize the available evidence on DSP cardiomyopathy and to identify existing gaps in knowledge that need clarification from upcoming research.
