The new HFA/ICOS risk assessment tool to identify patients with chronic myeloid leukaemia at high risk of cardiotoxicity
AimsTyrosine kinase inhibitors (TKIs) used to treat chronic myeloid leukaemia (CML) can cause cardiovascular adverseevents. So far, the Systematic Coronary Risk Evaluation (SCORE) charts of the European Society of Cardiology (ESC) have beenused to identify cancer patients at increased cardiovascular risk. The primary aim of our study was to evaluate the usefulnessof the new cardiovascular risk assessment model proposed by the Cardio-Oncology Study Group of the Heart Failure Associ-ation (HFA) of the ESC in collaboration with the International Cardio-Oncology Society (ICOS) to stratify the cardiovascular riskin CML patients, compared with SCORE risk charts. The secondary aim was to establish the incidence of adverse arterial events(AEs) in patients with CML treated with TKIs and the influence of preventive treatment with aspirin.Methods and resultsA retrospective single-centre observational study was carried out on 58 patients (32 men and 26women; mean age ± SD: 59 ± 15 years) with CML treated with TKIs for a median period of 43 ± 31 months. Cardiological eval-uation was performed and cardiovascular risk was estimated with SCORE risk charts and with the new risk assessment toolproposed by HFA/ICOS. AEs were recorded. According to SCORE charts and the new HFA/ICOS risk stratification tool, respec-tively, 46% (Group A1) and 60% (Group A2) of patients were at high–very high risk, and 54% (Group B1) and 40% (Group B2) atlow–moderate risk. AEs were significantly more frequent in Group A1 than Group B1 (Pvalue<0.01) when considered overall;they were significantly more frequent in Group A2 than Group B2 either overall or considered individually. HFA/ICOS risk strat-ification tool was significantly more sensitive than SCORE (P<0.01) in identifying patients at higher risk of cardiovascular tox-icity. In addition, we did notfind AEs in patients pretreated with aspirin.ConclusionsThe new HFA/ICOS risk stratification model allows a more tailored cardiovascular risk stratification in patientswith CML and it is more sensitive than SCORE chart
FePc Adsorption on the Moir\'e Superstructure of Graphene Intercalated with a Co Layer
The moir\'e superstructure of graphene grown on metals can drive the assembly
of molecular architectures, as iron-phthalocyanine (FePc) molecules, allowing
for the production of artificial molecular configurations. A detailed analysis
of the Gr/Co interaction upon intercalation (including a modelling of the
resulting moir\'e pattern) is performed here by density functional theory,
which provides an accurate description of the template as a function of the
corrugation parameters. The theoretical results are a preliminary step to
describe the interaction process of the FePc molecules adsorption on the Gr/Co
system. Core level photoemission and absorption spectroscopies have been
employed to control the preferential adsorption regions of the FePc on the
graphene moir\'e superstructure and the interaction of the central Fe ion with
the underlying Co. Our results show that upon molecular adsorption the distance
of C atoms from the Co template mainly drives the strength of the
molecules-substrate interaction, thereby allowing for locally different
electronic properties within the corrugated interface.Comment: This document is the Accepted Manuscript version of a Published Work

Stress echocardiography in heart failure patients: additive value and caveats
Heart failure (HF) is a clinical syndrome characterized by well-defined signs and symptoms due to structural and/or myocardial functional impairment, resulting in raised intracardiac pressures and/or inadequate cardiac stroke volume at rest or during exercise. This could derive from direct ischemic myocardial injury or other chronic pathological conditions, including valvular heart disease (VHD) and primary myocardial disease. Early identification of HF etiology is essential for accurate diagnosis and initiation of early and appropriate treatment. Thus, the presence of accurate means for early diagnosis of HF symptoms or subclinical phases is fundamental, among which echocardiography being the first line diagnostic investigation. Echocardiography could be performed at rest, to identify overt structural and functional abnormalities or during physical or pharmacological stress, in order to elicit subclinical myocardial function impairment e.g. wall motion abnormalities and raised ventricular filling pressures. Beyond diagnosis of ischemic heart disease, stress echocardiography (SE) has recently shown its unique value for the evaluation of diastolic heart failure, VHD, non-ischemic cardiomyopathies and pulmonary hypertension, with recommendations from international societies in several clinical settings. All these features make SE an important additional tool, not only for diagnostic assessment, but also for prognostic stratification and therapeutic management of patients with HF. In this review, the unique value of SE in the evaluation of HF patients will be described, with the objective to provide an overview of the validated methods for each setting, particularly for HF management
A multidisciplinary approach for the emergency care of patients with left ventricular assist devices: A practical guide
The use of a left ventricular assist device (LVAD) as a bridge-to-transplantation or destination therapy to support cardiac function in patients with end-stage heart failure (HF) is increasing in all developed countries. However, the expertise needed to implant and manage patients referred for LVAD treatment is limited to a few reference centers, which are often located far from the patient's home. Although patients undergoing LVAD implantation should be permanently referred to the LVAD center for the management and follow-up of the device also after implantation, they would refer to the local healthcare service for routine assistance and urgent health issues related to the device or generic devices. Therefore, every clinician, from a bigger to a smaller center, should be prepared to manage LVAD carriers and the possible risks associated with LVAD management. Particularly, emergency treatment of patients with LVAD differs slightly from conventional emergency protocols and requires specific knowledge and a multidisciplinary approach to avoid ineffective treatment or dangerous consequences. This review aims to provide a standard protocol for managing emergency and urgency in patients with LVAD, elucidating the role of each healthcare professional and emphasizing the importance of collaboration between the emergency department, in-hospital ward, and LVAD reference center, as well as algorithms designed to ensure timely, adequate, and effective treatment to patients with LVAD.

Correlation of Left Ventricular Myocardial Work Indices with Invasive Measurement of Stroke Work in Patients with Advanced Heart Failure
ObjectivesThis study aimed to explore the correlation between left ventricular (LV) myocardial work (MW) indices and invasively-derived LV stroke work index (SWI) in a cohort of patients with advanced heart failure (AHF) considered for heart transplantation. BackgroundLeft ventricular MW has emerged as a promising tool for diagnostic and prognostic purposes in heart failure (HF) but its relationship with hemodynamic data derived from right heart catheterization (RHC) has not been assessed in patients with advanced heart failure yet. Materials and methodsConsecutive patients with AHF considered for heart transplantation from 2016 to 2021 performing RHC and echocardiography as part of the workup were included. Conventional LV functional parameters and LV MW indices, including LV global work index (GWI), LV global constructive work (GCW), LV global wasted work (GWW), LV global work efficiency (GWE), and other were calculated and compared with invasively-measured LV SWI. ResultsThe population included 44 patients. Median time between RHC and echocardiography was 0 days (IQR: 0-24). Median age was 60 years (IQR: 54-63). For the most part, etiology of HF was non-ischemic (61.4%) and all patients were either on class NYHA II (61.4%) or III (27.3%). Median left ventricular ejection fraction was 25% (IQR: 22.3-32.3), median NT-proBNP 1,377 pg/ml (IQR: 646-2570). LV global longitudinal strain (GLS) significantly correlated with LV SWI (r = -0.337; p = 0.031), whereas, LV ejection fraction (EF) did not (r = 0.308; p = 0.050). With regard to LV MW indices, some of them demonstrated correlation with LV SWI, particularly LV GWI (r = 0.425; p = 0.006), LV GCW (r = 0.506; p = 0.001), LV global positive work (LV GPW; r = 0.464; p = 0.003) and LV global systolic constructive work (GSCW; r = 0.471; p = 0.002). ConclusionAmong LV MW indices, LV GCW correlated better with invasively-derived SWI, potentially representing a powerful tool for a more comprehensive evaluation of myocardial function
Inter- and Intraobserver Variation in the Assessment of Preoperative Colostograms in Male Anorectal Malformations: An ARM-Net Consortium Survey
Aim: Male patients with anorectal malformations (ARM) are classified according to
presence and level of the recto-urinary fistula. This is traditionally established by a
preoperative high-pressure distal colostogram that may be variably interpreted by
different surgeons. The aim of this study was to evaluate the inter- and intraobserver
variation in the assessment by pediatric surgeons of preoperative colostograms with
respect to the level of the recto-urinary fistula.
Materials and Methods: Sixteen pediatric surgeons from 14 European centers
belonging to the ARM-Net Consortium twice scored 130 images of distal colostograms
taken in sagittal projection at a median age of 66 days of life (range: 4–1,106 days).
Surgeons were asked to classify the fistula in bulbar, prostatic, bladder-neck, no
fistula, and “unclear anatomy” example. Their assessments were compared with the
intraoperative findings (kappa) for two scoring rounds with an interval of 6 months
(intraobserver variation). Agreement among the surgeons’ scores (interobserver variation)
was also calculated using Krippendorff’s alpha. A kappa over 0.75 is considered
excellent, between 0.40 and 0.75 fair to good, and below 0.40 poor. Surgeons were
asked to score the images in “poor” and “good” quality and to provide their years of
experience in ARM treatment.
Results: Agreement between the image-based rating of surgeons and the intraoperative
findings ranges from 0.06 to 0.45 (mean 0.31). Interobserver variation is higher
(Krippendorff’s alpha between 0.40 and 0.45). Years of experience in ARM treatment
does not seem to influence the scoring. The mean intraobserver variation between
the two rounds is 0.64. Overall, the quality of the images is considered poor. Images
categorized as having a good quality result in a statistically significant higher kappa
(mean: 0.36 and 0.37 in the first and second round, respectively) than in the group of
bad-quality images (mean: 0.25 and 0.23, respectively).
Conclusions: There is poor agreement among experienced pediatric colorectal
surgeons on preoperative colostograms. Techniques and analyses of images need to be
improved in order to generate a homogeneous series of patients and make comparison
of outcomes reliable
Exploring changes in children’s well-being due to COVID-19 restrictions: the Italian EpaS-ISS study
BackgroundWhile existing research has explored changes in health behaviours among adults and adolescents due to the COVID-19 outbreak, the impact of quarantine on young children's well-being is still less clear. Moreover, most of the published studies were carried out on small and non-representative samples. The aim of the EpaS-ISS study was to describe the impact of the COVID-19 pandemic on the habits and behaviours of a representative sample of school children aged mainly 8-9 years and their families living in Italy, exploring the changes in children's well-being during the COVID-19 pandemic compared to the immediately preceding time period.MethodsData were collected using a web questionnaire. The target population was parents of children attending third-grade primary schools and living in Italy. A cluster sample design was adopted. A Well-Being Score (WBS) was calculated by summing the scores from 10 items concerning the children's well-being. Associations between WBS and socio-demographic variables and other variables were analysed.ResultsA total of 4863 families participated. The children's WBS decreased during COVID-19 (median value from 31 to 25; p = 0.000). The most statistically significant variables related to a worsening children's WBS were: time of school closure, female gender, living in a house with only a small and unliveable outdoor area, high parents' educational level and worsening financial situation.ConclusionsAccording to parents ' perception, changes in daily routine during COVID-19 negatively affected children's well-being. This study has identified some personal and contextual variables associated with the worsening of children's WBS, which should be considered in case of similar events
How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons
COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice
Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy
IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical
attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced
colorectal cancers at diagnosis.
OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced
oncologic stage and change in clinical presentation for patients with colorectal cancer.
DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all
17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December
31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period),
in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was
30 days from surgery.
EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery,
palliative procedures, and atypical or segmental resections.
MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer
at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as
cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding,
lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery,
and palliative surgery. The independent association between the pandemic period and the outcomes
was assessed using multivariate random-effects logistic regression, with hospital as the cluster
variable.
RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years)
underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142
(56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was
significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR],
1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic
lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03).
CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the
SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients
undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for
these patients
Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study
Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak.
Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study.
Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM.
Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide
