Doctor-patient care relationship in genetic cardiomyopathies: An exploratory study on clinical consultations

BackgroundThe present study aims to explore the setting of consultation and communication between physicians and patients affected by genetic cardiomyopathies, investigating how the two parts of the therapeutic relationship participate and share information.Methods and results45 adult patients affected by various cardiomyopathies took part in a prospective case study while attending consultations at a cardiologic outpatient clinic constituting an Italian referral centre for cardiomyopathies. A researcher observed the consultations, which were audio-recorded and transcribed. Transcripts were coded and an analysis of setting, type of communication implemented and participation of doctors and patients in terms of word-count and type of questions/answers was carried out. Overall word-count was significantly higher for physicians than for patients (t(44) = 9,506; pConclusionsFindings emphasize patients' need for adequate time and space to share their subjective illness experience with the physician, within an approach informed by the insights and recommendations of Narrative Medicine. These findings are instrumental to improving the specific clinical setting for individuals with genetic cardiomyopathies

Continuità delle cure e gestione ambulatoriale dei pazienti con malattie primitive del miocardio durante la pandemia COVID-19: l’esperienza della Unit Cardiomiopatie dell’Azienda Ospedaliero-Universitaria di Careggi

Le misure restrittive imposte dalla pandemia COVID-19 hanno reso necessario una veloce riorganizzazione del lavoro dei sanitari per garantire una continuità delle cure per i pazienti affetti da malattie croniche, spesso cambiando strategie in corso d’opera. Riportiamo un'esperienza nel complesso molto positiva vissuta presso la Unit Cardiomiopatie dell’Azienda Ospedaliero-Universitaria di Careggi durante il recente lockdown

Unusual detection of lathosterol in amniotic fluids investigated for the determination of cholesterol and 7-dehydrocholesterol for suspected Smith-Lemli-Opitz Syndrome

The Smith-Lemli-Opitz syndrome (SLOS), is an autosomal recessive disorder caused by a 7-dehydrocholesterol reductase deficiency, which is characterized by abnormally elevated amniotic fluid 7-DHC (7-dehydrocholesterol) concentrations. A GC/FID (gas-chromatography with a flame ionization detector) and GC/MS (gas-chromatography with a mass detector) method was optimized for the detection of cholesterol and 7-DHC in amniotic fluids. The quantitative determination of cholesterol in 39 control amniotic fluids evidenced that between the fourth and fifth month of pregnancy the levels of this analyte are quite constant, the concentration of total and free cholesterol being respectively 10.3 \u3bcg\ub7mL 121 (SD = \ub13.6) and 1.7 \u3bcg\ub7mL 121 (SD = \ub10.91), while the analysis of 60 amniotic fluids potentially related to SLOS, showed a higher variability of cholesterol levels. Moreover, in 13 samples an analyte which did not correspond either to cholesterol or to 7-DHC was detected. A GC/MS investigation allowed us to identify this compound as lathosterol, a precursor of cholesterol in the biosynthetic pathwa

are drug eluting stents superior to bare metal stents in patients with unprotected non bifurcational left main disease insights from a multicentre registry

Aims To compare long-term clinical outcome following drug-eluting stents (DES) or bare-metal stents (BMS) implantation on lesions located at the ostium or the shaft of the left main in a large real-world population. The advent of DES decreased the risk of unprotected left main coronary artery (ULMCA) restenosis when compared with BMS, but it is unclear if this advantage continues when non-bifurcational lesions are considered. Methods and results The GISE-SICI registry is a retrospective, observational multicentre registry promoted by the Italian Society of Invasive Cardiology in which 19 high-volume participating centres enrolled 1453 consecutive patients who underwent percutaneous coronary intervention on ULMCA between January 2002 and December 2006. From the registry, a total of 479 consecutive patients with ostial and shaft lesions who underwent DES ( n = 334) or BMS ( n = 145) implantation were analysed with extensive multivariable and propensity score adjustments. At 3-year follow-up, risk-adjusted survival rates were higher in patients treated with DES than in those treated with BMS. The adjusted hazard ratio (HR) for the risk of mortality after DES implantation relative to BMS implantation was 0.37 (95% CI: 0.15–0.96, P = 0.04). The adjusted HR for the risk of cardiac mortality was 0.31 (95% CI: 0.09–1.04, P = 0.06). The adjusted 3-year rates of target lesion revascularization (TLR) were not significantly lower in the DES group than in the BMS group ( P = 0.60). Conclusion In a large population of patients with lesions located at the ostium or the shaft of the left main in a real-world setting, DES were associated with favourable clinical outcomes when compared with BMS, although there was no evidence of a significant reduction in TLR with DES vs. BMS

Electrocardiogram analysis in Anderson-Fabry disease: a valuable tool for progressive phenotypic expression tracking

BackgroundElectrocardiogram (ECG) has proven to be useful for early detection of cardiac involvement in Anderson-Fabry disease (AFD); however, little evidence is available on the association between ECG alterations and the progression of the disease.Aim and MethodsTo perform a cross sectional comparison of ECG abnormalities throughout different left ventricular hypertrophy (LVH) severity subgroups, providing ECG patterns specific of the progressive AFD stages. 189 AFD patients from a multicenter cohort underwent comprehensive ECG analysis, echocardiography, and clinical evaluation.ResultsThe study cohort (39% males, median age 47 years, 68% classical AFD) was divided into 4 groups according to different degree of left ventricular (LV) thickness: group A & LE; 9 mm (n = 52, 28%); group B 10-14 mm (n = 76, 40%); group C 15-19 mm (n = 46, 24%); group D & GE; 20 mm (n = 15, 8%). The most frequent conduction delay was right bundle branch block (RBBB), incomplete in groups B and C (20%,22%) and complete RBBB in group D (54%, p < 0.001); none of the patients had left bundle branch block (LBBB). Left anterior fascicular block, LVH criteria, negative T waves, ST depression were more common in the advanced stages of the disease (p < 0.001). Summarizing our results, we suggested ECG patterns representative of the different AFD stages as assessed by the increases in LV thickness over time (Central Figure). Patients from group A showed mostly a normal ECG (77%) or minor anomalies like LVH criteria (8%) and delta wave/slurred QR onset + borderline PR (8%). Differently, patients from groups B and C exhibited more heterogeneous ECG patterns: LVH (17%; 7% respectively); LVH + LV strain (9%; 17%); incomplete RBBB + repolarization abnormalities (8%; 9%), more frequently associated with LVH criteria in group C than B (8%; 15%). Finally, patients from group D showed very peculiar ECG patterns, represented by complete RBBB + LVH and repolarization abnormalities (40%), sometimes associated with QRS fragmentation (13%).ConclusionsECG is a sensitive tool for early identification and long-term monitoring of cardiac involvement in patients with AFD, providing "instantaneous pictures" along the natural history of AFD. Whether ECG changes may be associated with clinical events remains to be determined

Synthesis of new dithiolethione and methanethiosulfonate systems endowed with pharmaceutical interest

Here we report synthetic methodology affording in the most efficient way the rapid preparation of new dithiolethiones (DTTs) and methanethiosulfonates (MTSs). These were evaluated as STAT3 inhibitors since these electrophilic systems could react with thiol groups of STAT3-SH2 domain. The results showed that MTSs strongly interacted with the SH2 domain, whereas the corresponding DTTs possessed lower affinity, independently from the nature of the linked heterocyclic scaffold

Synthesis, structure–activity relationships andstereochemical investigations of new tricyclic pyridazinone derivatives as potential STAT3 inhibitors

Through a cell-based biological screening, the benzocinnolinone derivative 2c was identified as a promising STAT3 inhibitor. Since SAR studies on a series of compounds structurally related to 2c (1c, 2a\u2013p, 3c, 4c, 6) showed that the latter had the most significant inhibitory activity, we investigated in depth its essential structural features. In particular, enantiomeric separation was performed, and the absolute configuration of the stereoisomers was assigned by theoretical and crystallographic studies.The biological evaluation highlighted that (S)-(-)-2c is twice as potent as (R)-(+)-2c
