[Psychological impact of the announcement of an abnormal cervical smear: How to improve patient experience and information? COLANX: a multicenter study in Seine-Maritime]

INTRODUCTION

When an anomaly in the screening by cervical smear or by the HPV-HR test is detected, the women are called for a colposcopy. Waiting for colposcopy is often an anxiety-provoking situation for women, probably linked to a widespread ignorance of the value of screening and the pathophysiology of HPV infection.

METHODS

The COLANX was a multicentric study, in Seine-Maritime, conducted with 8 colposcopist practitioners. Self-questionnaires were distributed to volunteer women, summoned for a first abnormal smear result, at the exit of colposcopy and filled out immediately on site. This questionnaire evaluated: the psychological impact of the announcement of the abnormal cervico-uterine smear, its impact on the sexual quality of life, the epidemiological characteristics of the population studied, the modalities of the announcement made of the abnormal result, the satisfaction of the women and their desire for additional information. 131 questionnaires were included, from June 1, 2020 to January 18, 2021.

RESULTS

61.5% of responding women presented proven psychological distress, as evidenced by a GHQ-12 score ≥ 2. The state of psychological distress was significantly different depending on the time left by the practitioner between the announcement of the abnormal cytology result and the colposcopy appointment. The GHQ-12 score was significantly different according to the initial classification of the cervico-uterine smear, high in case of suspicion of high-grade lesions in particular. 36.3% of patients had a significant deterioration in their sexual quality of life, demonstrated by an ASEX score ≥ 18. The women were statistically more satisfied when the announcement of their abnormal screening result had been made by telephone or during a consultation, rather than by mail, but no significant difference was found on the presence or absence of distress psychological according to this mode of announcement. 52.3% of the women in this study expressed a request for additional information support, preferably written support (for 89.4% of these women), to be delivered when the abnormal screening was announced (for 76, 5% of these women).

DISCUSSION

The main results of the COLANX study are consistent with those of the literature, in particular concerning the negative psychological impact in the announcement of an abnormal smear result.

CONCLUSION

The new methods of organized screening will increase the use of colposcopy for many women. There is a significant impact on their psyche and their intimate life. The issuance of additional information during this announcement would probably reduce this anxiety.

Background

The aetiology of left ventricular hypertrophy (LVH) is a relevant clinical challenge with consequences for patient management. Phenotypes resulting from hypertensive remodelling and sarcomere mutation often overlap. Synchrotron X-ray phase-contrast imaging (X-PCI) is a technique that can provide 3-dimensional detailed information on myocardial micro-structure non-destructively. The aim is to relate macrostructural/functional, non-invasive, imaging phenotypes of hypertrophic cardiomyopathy (HCM) to the underlying myocardial microstructure assessed with X-PCI.

Methods

Myocardial tissue samples were obtained from three patients (P1-3) with obstructive myocardial hypertrophy undergoing septal myectomy. Medical history and the 5-year HCM risk scores were evaluated. The patients were imaged with magnetic resonance imaging and echocardiography prior to procedure. Myocardial structure was assessed with wall thickness, late gadolinium enhancement (LGE), whereas function with speckle-tracking deformation (STE) and tissue Doppler imaging (TDI). Myectomy tissue was imaged with X-PCI in the TOMCAT beamline, using a multiscale propagation-based protocol combining a low-resolution (LR) and a high-resolution (HR) setup (5.8 and 0.7 um pixel size, respectively).

Results

The clinical and imaging data are shown in Fig 1. On initial assessment, wall thickness, LGE distribution, global longitudinal strain and septal TDI demonstrated a similar macrostructural and functional phenotype of P1 and P2, whereas P3 stood out with more severe hypertrophy, scarring and dysfunction. Additional regional deformation analysis with STE revealed reduced deformation in the basal and mid septum in P1, paired with a hypertensive pattern of post-systolic shortening (PSS) (yellow arrows). In comparison, in P2 and P3, deformation was more heterogeneous regionally, with regions of almost complete absence of deformation (orange arrows). Upon further exploration with TDI, areas with abnormal deformation were identified on the transition from basal to mid septum in both P2 and P3, whereas deformation was normal, but reduced in P1, and paired with PSS. LR X-PCI defined regions of interest to scan with HR (yellow frame), where HR revealed extensive interstitial fibrosis (orange arrow) with normal myocyte size and organisation in P1, compatible with severe hypertensive remodelling. However, in P2 and P3, patches of fibrosis (yellow arrow) paired with enlarged myocytes organized in visible disarray, considerably more prominent in P3, were both compatible with sarcomere-mutation HCM.

Conclusion

The results demonstrate multiscale phenotyping of HCM - relating micro- and macrostructural findings to function, and integrating multimodality data. In-depth regional deformation analysis, validated by synchrotron-based microstructural analysis, showed potential to identify distinct imaging phenotypes in HCM, distinguishing between overlapping presentations in different aetiologies.

Long-term follow-up of patients with Chagas cardiomyopathy living in a non-endemic area: moving towards identification of early markers of disease progression

Background

The number of patients with Chagas disease residing in Europe has increased significantly due to migration flows. Globally, Chagas cardiomyopathy has worse prognosis than other types of dilated cardiomyopathies and about 30% of patients develop cardiac involvement after a variable latency period (10–30 years). However, there is lack of data regarding the evolution of patients with Chagas disease living in a non-endemic area and potential early predictors of disease progression.

OBJETIVE

To describe the natural course of Chagas disease, the incidence rate of transformation into cardiac form and to assess if early predictors of myocardial involvement translate into a worse long-term prognosis in our non-endemic cohort.

Methods

Clinical and echocardiographic follow-up was performed in 202 individuals from endemic areas of Chagas disease. At baseline, electrocardiogram, BNP and a comprehensive echocardiography including diastolic function and longitudinal myocardial strain were performed. Four different groups were defined: healthy controls (N=77); Chagas indeterminate form (positive serology, normal ECG and left ventricle (LV) dimensions and LV ejection fraction (>50%) and no segmental abnormalities, N=92); Chagas patients with abnormal ECG but normal LV dimensions and motility (N=15); and Chagas patients with LV diameter>55 mm or LV ejection fraction<50% or segmental abnormalities (N=18). The primary clinical outcome included advanced atrioventricular block, sustained ventricular tachycardia, heart failure, heart transplant, death or progression of cardiac disease defined as LV systolic dysfunction or new segmental abnormalities. Kaplan Meier with Long rank test and Cox regression analysis was used.

Results

Mean age was 37±9 and 34% were male. Median follow-up was 69 months (range 1 to 147). The primary endpoint occurred in a total of 17 (8.4%) individuals: 5 (5.4%) in the Indeterminate group; 3 (20%) in the abnormal ECG group; and 9 (50%) in the group with abnormal LV dimension or motility, with no events among controls (long-rank test<0.01, Figure 2). Six patients evolved from the indeterminate phase to cardiac involvement (2 with isolated ECG changes and 4 with abnormal echocardiography without previous changes in ECG (Figure 1). On echocardiography, there were no differences regarding changes in LV dimensions or LV ejection fraction between Chagas patients with normal baseline echo and controls, but a significantly reduction of Em was observed (−1.6±3.0 vs. 0.2±1.0) in the former. Excluding patients with abnormal echo at baseline, BNP (HR=1.03, p=0.001), Em (HR=0.78, p=0.05) and left atrial diameter (1.23, p=0.01) were predictors of the combined event.

Conclusions

Conversion from the indeterminate to Chagas cardiomyopathy in our cohort was approximately 1.1%/year, but it may happen directly with contractility disturbances. BNP and comprehensive echocardiography may help to early detect disease progression.

Electromechanical delay by speckle-tracking echocardiography: a novel tool for distinguishing between Brugada syndrome and isolated right bundle branch block

Background

The electrocardiographic (ECG) definition of Brugada syndrome (BS) can be challenging because benign ECG abnormalities, such as right bundle branch block (RBBB), may mimic pathological ECG characteristics of BrS. However, although myocardial delay and deformation can be quantified by advanced imaging, it has not yet been used to differentiate between BrS and RBBB.

Purpose

The aim of this study was to characterize the electro-mechanical behavior of the heart of patients with type-1 BrS and subjects with isolated complete RBBB in order to differentiate these conditions.

Methods

In this two-center study, 66 subjects were analyzed by standard and speckle-tracking echocardiography (STE): 22 type-1 BrS, 24 isolated complete RBBB, and 20 healthy subjects. The participants were not treated by any drug potentially influencing myocardial conduction.

Results

Standard echocardiographic parameters did not differ among the groups. STE demonstrated that right ventricular (RV) mechanical dispersion (MD) was greater in RBBB as compared to BrS and controls (p<0.05). In patients with isolated RBBB, the greatest delay of RV time-to-peak longitudinal strain (TTP) was found in RV free-wall basal segments. Mean absolute deviations of TTP calculated for each left ventricular (LV) region were greater in patients with RBBB as compared to those with BrS and to controls with a localisation of the delay in LV antero-septal, anterior, lateral, and infero-septal basal segments (figure 1).

Conclusions

Advanced echocardiographic techniques may help to differentiate between BrS and RBBB. Indeed, STE allows to identify an electro-mechanical conduction delay in RBBB patients that is not found in patients affected by type-1 BrS.

P1721 Reversible heart right failure. Pulmonary hypertension induced by Tyrosine Kinase Inhibitors

BACKGROUND

Pharmacologically induced pulmonary hypertension (PH) is infrequent nowadays and it is included in the type 1 of the classification of PH.

Tyrosine kinase inhibitors (TKI) are the cornerstone of the treatment of many haemotopoietic stem cell diseases. Dasatinib is a second-generation TKI used in chronic myeloid leukemia (CML) and as an infrequent cardiovascular side-effect (< 0,50%) could induce PH, usually reversible but life threatening. Only a few case series are published.

CASE DESCRIPTION: We present a 51-year-old woman who was diagnosed of a CML when she was 46. Initially, she underwent therapy with imatinib but after 5 years of treatment she developed resistance to this drug, and dasatinib was prescribed as a second line drug. After 3 months of continuous treatment, she started with dry cough and effort dyspnea. Blood analysis, EKG and Chest X-Ray were made but did not show outstanding findings. An unspecific viral infection was the final diagnosis. The patient clinical condition deteriorated with major dyspnea and edemas in the lower limbs. A TTE showed moderate tricuspid regurgitation and severe HP systolic pulmonary artery pressure (sPAP) of 80 mmHg. The pulmonary acceleration time was shortened and a mesosistolic knock was present. Systolic dysfunction of the right ventricle and pericardial effusion (image 1,2,3,4) were noted. The right atrium was not dilated. Cava vein was dilated but with inspiratory collapse >50%. The left ventricular function was preserved, but first degree diastolic dysfunction was found. Other causes of PH were excluded (types 2, 3, 4). A CT pulmonary angiogram did not show segmental perfusion defects. Finally, a right heart catheterization confirmed the TTE findings: severe precapillary PH without postcapillary component. After the diagnosis was confirmed, TKI was stopped and double targeted therapy with ambrisentan + tadalafil was started. After 6 months of treatment a new TTE was made with complete reversal of the secondary changes in the myocardium induced by the PH. No tricuspid regurgitation was detected nor any indirect sign of PH was found. (image 5,6).

CONCLUSIONS

Drug-induced PH is rare nowadays and most cases were described in the seventies in the USA related with the epidemic of anorexigenic drugs. Although the pathogenesis still remains unclear, treatment includes immediately stopping the offending agent.

Echocardiography due to its accessibility, reproducibility, consistence and low cost should be the first diagnostic tool to be considered, because as it is known, in the early stages of the disease, before developing right disfunction, clinical and conventional tests are non-specific.

P4684Differential right ventricular adaptation patterns to chronic pressure overload

Background

Right ventricular (RV) dysfunction is the most important prognostic factor in chronic pulmonary hypertension (PH), but its underlying mechanisms are unknown. Clinical observation and prior experimental work suggest that RV pressure overload is not the only cause since the degree of RV adaptation varies with similar RV end-systolic pressures.

Purpose

Our aim was to characterize serial RV adaptation by cardiac magnetic resonance (CMR) in 3 different experimental large-animal models of increased afterload: a model of chronic postcapillary PH, a model of PH secondary to systemic-to-pulmonary shunt and a model of mechanical RV pressure overload (generated by pulmonary artery [PA] banding).

Methods

Four-week old piglets underwent pulmonary vein banding surgery to generate the chronic postcapillary PH model (n=20), aorto-pulmonary shunt (n=6), PA banding (n=7) or sham operation (n=7). They were followed up monthly with CMR and right heart catheterization (RHC). All procedures followed the “Principles of laboratory animal care”. Comparison of continuous variables among groups was performed with Mann-Whitney U test.

Results

Animals with either postcapillary PH or PH secondary to aorto-pulmonary shunt presented significant RV dilatation, hypertrophy and dysfunction that was maintained during follow-up (median RV end-systolic volume [RVESV]=32.6 ml/m2 for postcapillary PH and 32.6 ml/m2 for shunt vs. 16.1 ml/m2 in sham controls; median RV ejection fraction [RVEF]=61.5% for postcapillary PH and 60.5% for shunt vs. 69.6% in sham controls at the end of follow-up). Animals with PA banding also presented with significant RV dilatation and hypertrophy at the first month follow-up, but unlike all other groups, they developed reverse RV remodeling from the second month onwards and maintained normal RV volumes and RVEF values until the end of follow-up despite having severe RV hypertrophy (RV mass 22.6 g/m2 in PA banding vs. 16.1 g/m2 in controls at the 4th month follow-up; Figure).

CMR parameters (median values).

Conclusion

In PH there is a maladaptive RV hypertrophy that is not present in a model of progressive RV pressure overload without alterations of the pulmonary circulation. Increased RV pressure overload alone does not fully explain PH-associated RV dysfunction. Further research is needed to clarify the underlying mechanisms of adaptive and maladaptive hypertrophy in PH.

P596Early markers of right ventricular involvement in experimental chronic postcapillary pulmonary hypertension

Background

In chronic pulmonary hypertension (PH), the main cause of death is right ventricular (RV) failure. However, the onset of RV dysfunction varies significantly among patients. Early recognition of RV maladaptation would be highly relevant.

Purpose

To identify cardiac magnetic resonance (CMR)-derived parameters affected in early stages of PH before the development of RV dysfunction.

Methods

Experimental chronic PH was generated by pulmonary vein banding in 76 pigs whereas 14 animals underwent sham operation. Animals were followed-up monthly with right heart catheterization (RHC) and immediate CMR for a maximum of 9 months. CMR exams included a T1-mapping sequence to quantify equilibrium-extracellular volume (ECV) at the RV insertion points. Pairs of RHC and CMR examinations were compared among controls and PH with normal RV ejection fraction (RVEF≥55%) or reduced (REVF<55%) using ANCOVA test with Bonferroni correction. All procedures followed the “Principles of laboratory animal care”.

Results

In the presence of PH confirmed by RHC and normal RVEF, the RV displays significant hypertrophy and increased myocardial native T1 and ECV, despite preserved ventricular dimensions and PA flow (Fig 1B). In advanced stages of the disease, RV-AP uncoupling and reduced PA pulsatility develop together with RV dilatation and failure (Fig 1C).

Conclusion

RV hypertrophy and ECV expansion are early mechanisms in RV adaptation to postcapillary PH, whereas ventricular and PA dilatation, RV-PA uncoupling and reduced pulsatility appear in more advanced stages concurring with systolic dysfunction.

P1810May early myocardial involvement detection in chagas disease have a prognosis impact?

Background

Brain natriuretic peptide (BNP) and novel echocardiographic techniques such as speckle-tracking and a comprehensive evaluation of diastolic function can detect early myocardial involvement in patients with Chagas disease. However, there is lack of longitudinal studies that can confirm whether this early myocardial involvement translates into a worse prognosis.

Purpose

To assess if early myocardial involvement detected by BNP or a comprehensive echocardiographic evaluation was associated with future events in Chagas disease.

Methods

182 consecutive individuals from endemic areas who underwent T. cruzi screening where prospectively included from 2007 to 2014. ECG, BNP and a comprehensive echocardiography including diastolic function and longitudinal myocardial strain were performed. Four different groups were defined: healthy controls (N=77); Chagas indeterminate form (positive serology, normal ECG and left ventricle (LV) diameter (<55 mm), LV ejection fraction (>50%) and no segmental abnormalities, N=88); Chagas patients with abnormal ECG but normal LV dimensions and motility (N=7); and Chagas patients with LV diameter>55 mm or LV ejection fraction<50% or segmental abnormalities (N=13). The primary outcome included advanced atrioventricular block, sustained ventricular tachycardia, heart failure, heart transplant or death. Kaplan Meier with Long rank test and Cox regression analysis was used.

Results

Mean age was 37±9 and 34% were male. Median follow-up was 63 months (range 1 to 137). The primary endpoint occurred in a total of 11 (10%) individuals: 2 (2.4%) in the Indeterminate group; 3 (43%) in the abnormal ECG group; and 6 (46%) in the group with abnormal LV dimension or motility, with no events among controls (long-rank test<0.01, Figure). In the global population, age, BNP, diastolic dysfunction parameters and longitudinal strain at the inferior and lateral walls were significant predictors. In the cohort of Chagas patients with normal standard echocardiography (N=92), ECG abnormalities (HR=49, p=0.001), Em (HR=0.68, p=0.03), deceleration time (HR=0.01, p=0.01), left atrial diameter (HR=1.24, p<0.01) and longitudinal strain at the midventricular lateral wall (HR=0.75, p=0.028) remained significantly associated with outcome.

Cumulative survival without events

Conclusions

Outcome was significantly more frequent in Chagas patients with abnormalities in ECG or standard echocardiography. In early forms of the disease, myocardial involvement detected by BNP or a comprehensive echocardiography was associated with prognosis, and may help to individualize treatment and follow-up.

[Psychoneuroses of paternity. Puerperal psychoneuroses in man]

Psychotic, neurotic and psychosomatic disturbances, directly promoted by fatherhood condition, seem more frequent than the small number of publications about this subject allow to suppose. Twenty original observations are expounded and discussed; they allow the importance of basic psychological ground; it is necessary to differentiate distinctly between initial paternity disturbances, among immature patients, inducing total disorder, and multiple paternity perturbations where anxiety and culpability feeling prevail. Regarding these disturbances and the sociological phenomenon of the "couvade", the real puerperality in men is investigated in connection with the personal and relational structure of the individual.
