Scabies represents a global health issue and in 2017 was added to the World Health Organization's list of neglected tropical diseases. In European and Middle Eastern countries, cases are sporadic while recent surveillance data have pointed out an increasing incidence among vulnerable populations. Regional cases for Lazio, Italy, reported from 2017 to 2023 to the national infectious disease surveillance system were analyzed. In Lazio, just after the coronavirus disease 2019 (COVID-19) pandemic onset, a significant and immediate reduction in the incidence of scabies was recorded (- 79.6%) followed by a progressive and relevant increase (143.4% from 2020 to 2021, 142.3% from 2021 to 2022 and 170.3% from 2022 to 2023). Consistently, the number of scabies outbreaks, after a decrease following the first COVID-19 wave, has progressively increased over time, mainly due to the occurrence of outbreaks in long term facilities (750% from 2020 to 2023). The increased incidence may also be driven by the "pseudo-resistance" phenomenon (under dosed/early-discontinued treatment, suboptimal adherence, reduced drug bioavailability), but also by reduced in-vitro susceptibility to the mainly used scabicides. The rapidly evolving epidemiology of scabies in our country, as documented also in other regions, calls for a comprehensive approach to effectively address the problem., Competing Interests: Declarations.

Background: The coronavirus disease 2019 (COVID-19) emergency has represented a profound upheaval in the dynamics of infectious diseases transmission worldwide. This phenomenon has been at least in part driven by the introduction of non-pharmaceutical interventions (NPIs), implemented to counteract viral transmission. Our study aimed to assess the magnitude and the features of the impact of the COVID-19 pandemic on the incidence of notifiable infectious diseases (NIDs) in the Lazio region, Italy., Methods: Data on NIDs in the Lazio Region with symptom onset date included in the time interval from 1 January 2017 to 31 December 2023 were collected from different surveillance system databases available at SERESMI/Lazio Region Unit and classified into five categories based on the main transmission route of the disease. Descriptive statistics were performed and interrupted time series (ITS) analysis was used to assess the effect of the COVID-19 pandemic and subsequent recovery period on monthly NIDs cases., Results: Immediately after the start of the COVID-19 pandemic, a significant, sharp and immediate reduction in monthly cases was recorded for all NIDs (-86.73%), regardless of the transmission route. The decrease was particularly significant for vector-borne, food-borne and respiratory-transmitted diseases (RDs), and in general in females. During the COVID-19 recovery phase, monthly cases of all NIDs showed a significant positive level change, particularly significant for sexually transmitted/blood-borne diseases, contact diseases and RDs., Discussion: The COVID-19 pandemic has been responsible for the disruption of all NIDs transmission patterns, while the magnitude and dynamics of its effects varied depending on the transmission route; furthermore, the impact of the pandemic wave was still noticeable during the post-COVID-19 era and the incidence trajectories of NIDs in this phase were peculiar for each disease category., Competing Interests: Declarations.

Background: Since August to November 2023, 82 cases of autochthonous or non-travel related Dengue virus (DENV) infection have been reported in Italy, highlighting a concerning trend of local transmission. We describe the clinical and laboratory findings of 10 autochthonous DENV in the metropolitan area of Rome admitted to the Lazzaro Spallanzani National Institute for Infectious Diseases., Method and Results: Ten patients (3 males, 7 females; median age: 51) with classic dengue fever symptoms were admitted between August and November 2023. Laboratory tests confirmed dengue infection through DENV non-structural protein 1 and/or immunoglobulins (IgM/IgG) positive tests, moreover leukopenia, thrombocytopenia, elevated transaminases were detected. A subset of patients underwent extensive biological sampling, including real-time RT-PCR and immunofluorescence, to monitor DENV-RNA and antibody levels over 30 days. DENV-1 was detected in 8 patients and DENV-3 in 2. Upon admission specific IgM antibodies were found in 7 patients while IgG antibodies in 4 patients. DENV RNA was consistently detected in blood within the first 8 days but was less common in saliva and urine. No DENV RNA was detected after day 24., Conclusion: These findings contribute to the understanding of the clinical course of DENV infection in a non-endemic setting as integrated epidemiological and clinical model to increase syndromic surveillance and timely diagnosis of DENV infections., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objectives: To investigate whether Mycobacterium tuberculosis (Mtb) DNA is detected in peripheral blood mononuclear cells (PBMC) of subjects with tuberculosis (TB) or TB infection (TBI) living in a low-burden country., Methods: We prospectively enrolled 57 patients with TB, 41 subjects with TBI, and 39 controls in Rome, Italy. PBMC were isolated, cluster of differentiation (CD)34 + and CD34 - cells were immunomagnetic separated, DNA was extracted, and digital polymerase chain reaction for IS6110 and rpoB sequences was used to detect Mtb DNA in PBMC subsets and unfractionated PBMC., Results: We detected Mtb DNA at a low copy number in CD34 + cells in 4o f 30 (13%) patients with TB, 2 of 24 (8%) subjects with TBI, and 1 of 24 (4%) controls. Mtb DNA was detected in unfractionated PBMC in 3 of 51 (6%) patients with TB, 2 of 38 (5%) subjects with TBI, and 2 of 36 (6%) controls. In CD34 - cells, only 1 of 31 (3%) subjects with TBI tested positive for Mtb DNA., Conclusions: Mtb DNA was detected at low frequencies and levels in the PBMC of subjects with TBI and donors with TB living in a low-burden country. In particular, Mtb DNA was detected more frequently in CD34 + cells, supporting the hypothesis that these cells may represent a Mtb niche. This finding informs biological understanding of Mtb pathogenesis and may support the development of a microbial blood biomarker for Mtb infection., Competing Interests: Declarations of competing interest DG reported the following competing interest: PBD Biotech.

Between August and September 2023, three distinct autochthonous dengue virus transmission events occurred in Lazio, Italy, with the main event in Rome. The events involved three different dengue serotypes. No link with previous imported cases was identified. Here we describe the epidemiological and phylogenetic analysis of the first autochthonous cases and the implemented control actions. The multiple transmission events call for a strengthening of the vector control strategies and future research to better characterise the risk in countries like Italy.

Objectives: A pre-exposure vaccination campaign to prevent the spread of the mpox virus was initiated in Italy in August 2022. We explore the possible factors affecting the trend of mpox cases in an Italian region (Lazio) with a rapid roll-out of the vaccination campaign., Methods: We estimated the impact of the communication and vaccination campaign by fitting a Poisson segmented regression model. Results By September 30, 2692, high-risk men who have sex with men had received at least one dose of vaccine, with a vaccination coverage of 37%. The analysis of surveillance data showed a significant decreasing trend in the number of mpox cases starting from the second week after vaccination (incidence rate ratio 0.452 [0.331-0.618])., Conclusion: The reported trend in mpox cases is likely to result from a combination of multiple social and public health factors combined with a vaccination campaign., Competing Interests: Declaration of competing interest The authors have no competing interests to declare., (Copyright © 2023 The Authors.

Aims: Sacubitril/valsartan has changed the treatment of heart failure with reduced ejection fraction (HFrEF), due to the positive effects on morbidity and mortality, partly mediated by left ventricular (LV) reverse remodelling (LVRR). The aim of this multicenter study was to identify echocardiographic predictors of LVRR after sacubitril/valsartan administration., Methods and Results: Patients with HFrEF requiring therapy with sacubitril/valsartan from 13 Italian centres were included. Echocardiographic parameters including LV global longitudinal strain (GLS) and global peak atrial longitudinal strain by speckle tracking echocardiography were measured to find the predictors of LVRR [= LV end-systolic volume reduction ≥10% and ejection fraction (LVEF) improvement ≥10% at follow-up] at 6 month follow-up as the primary endpoint. Changes in symptoms [New York Heart Association (NYHA) class] and neurohormonal activations [N-terminal pro-brain natriuretic peptide (NT-proBNP)] were also evaluated as secondary endpoints; 341 patients (excluding patients with poor acoustic windows and missing data) were analysed (mean age: 65 ± 10 years; 18% female, median LVEF 30% [inter-quartile range: 25-34]). At 6 month follow-up, 82 (24%) patients showed early complete response (LVRR and LVEF ≥ 35%), 55 (16%) early incomplete response (LVRR and LVEF < 35%), and 204 (60%) no response (no LVRR and LVEF < 35%). Non-ischaemic aetiology, a lower left atrial volume index, and a higher GLS were all independent predictors of LVRR at multivariable logistic analysis (all P < 0.01). A baseline GLS < -9.3% was significantly associated with early response (area under the curve 0.75, P < 0.0001). Left atrial strain was the best predictor of positive changes in NYHA class and NT-proBNP (all P < 0.05)., Conclusions: Speckle tracking echocardiography parameters at baseline could be useful to predict LVRR and clinical response to sacubitril-valsartan and could be used as a guide for treatment in patients with HFrEF., (© 2022 The Authors.

The prevalence of cardiac amyloidosis has progressively increased over the last years, being recognized as a significant cause of heart failure. In fact, the management of advanced heart failure is a cornerstone treatment of amyloid cardiomyopathy due to the frequent delay in its diagnosis. Left ventricular assist devices (LVADs) have been gaining importance in the scenario of end-stage heart failure, representing an alternative to heart transplant. However, only few studies have investigated the role of LVAD in restrictive cardiomyopathies such as cardiac amyloidosis, since there are several problems to consider. In fact, both anatomical factors and the restrictive physiology of this condition make LVAD implant a relevant challenge in this subset of patients. Furthermore, due to the systemic involvement of amyloidosis, several factors have to be considered after LVAD implant, such as an increased risk of bleeding and right ventricular failure. This review attempts to summarize the current evidence of LVAD in cardiac amyloidosis, especially focusing on the challenges that this cardiomyopathy imposes both to the implant and to its management thereafter., (© 2022.

Background: The relief of congestion is crucial to improve heart failure (HF) patient's quality of life and prognosis. N-terminal-pro-brain natriuretic peptide (NT-proBNP) is a well-known marker of congestion, although with limited specificity. Peak atrial longitudinal strain (PALS) by speckle tracking echocardiography (STE) is an index of intracardiac pressure and HF prognosis. We aimed to determine the association between NT-proBNP and PALS and its prognostic implications in patients with HF., Methods: Patients hospitalized for de-novo or recurrent HF and outpatients with chronic HF were included in this retrospective study. Patients with missing data, previous cardiac surgery, non-feasible STE were excluded. Clinical, laboratory and echocardiographic data were collected. STE was performed on echocardiographic records. Primary endpoint was a combination of all-cause death and HF hospitalization., Results: Overall, 388 patients were included (172 acute HF, 216 chronic HF, mean age = 65 ± 12 years, 37% female). Mean LV ejection fraction = 31 ± 9%. Global PALS showed a significant inverse correlation with NT-proBNP in acute and chronic HF (all p < 0.001). During a median follow-up of 4 years, 180 patients reached the combined endpoint. NT-proBNP (AUC = 0.87) and global PALS (AUC = 0.82) were good predictors of the combined endpoint. Global PALS was the only independent predictor of the combined endpoint. Optimal risk stratification for the composite endpoint was provided combining PALS ≤15% and NTproBNP ≥874.5 ng/l., Conclusions: Global PALS is associated with NT-proBNP in acute and chronic HF and may be used as additional index of congestion to optimize therapeutic management. The combination of global PALS and NT-proBNP could enhance the prognostic stratification of HF., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022 Elsevier B.V.

Objectives: This 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., Background: Left 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 Methods: Consecutive 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., Results: The 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)., Conclusion: Among LV MW indices, LV GCW correlated better with invasively-derived SWI, potentially representing a powerful tool for a more comprehensive evaluation of myocardial function., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Landra, Mandoli, Chiantini, Barilli, Merello, De Carli, Sciaccaluga, Lisi, Flamigni, D’Ascenzi, Focardi, Fineschi, Iadanza, Bernazzali, Maccherini, Valente and Cameli.)

Sharp injuries, determining the risk of bloodborne infections and psychological distress in healthcare workers, may be prevented by a set of strategies, legally enforced in Europe through the Directive 2010/32/EU. To assess its level of implementation in Italy, a national survey was conducted in 2017 and again in 2021, evaluating the progress and possible drawbacks of the COVID-19 pandemic. Altogether, 285 safety managers and 330 nurses from a representative sample of 97 and 117 public hospitals were interviewed using a standardized questionnaire. Knowledge of the Directive requirements decreased significantly, with <60% of participants answering correctly in 2021, and nurses' attendance in specific courses dropped to 25% in 2021 compared to 54% in 2017. Over 75% of hospitals introduced multiple safety-engineered devices (SED), though total replacement occurred in <50% of cases; routine SED availability increased for blood collection (89%) and venous access devices (83%). Incorrect behaviors in handling sharps decreased significantly over time. Nurses' HBV vaccination coverage was high (89% in both surveys); in the last year, 97% were vaccinated against COVID, and 47% against influenza. Average annual injuries per hospital did not increase significantly (32 in 2021 vs. 26 in 2017). In 2017, nurses' perceived safety barriers were working in emergency situations (49%) and lack of resources (40%); in 2021, understaffing (73%), physical fatigue (62%), and handling difficulties while wearing full protective equipment (59%). Safety measures were implemented in Italian hospitals, and although the average injuries per hospital did not show a decrease, these measures could have helped protect healthcare workers during the pandemic, mitigating its potential impact on the increase in situations at risk of injury.

Aim: To investigate the prevalence of amyloid cardiomyopathy (AC) and the diagnostic accuracy of echocardiographic red flags of AC among consecutive adult patients undergoing transthoracic echocardiogram for reason other than AC in 13 Italian institutions., Methods and Results: This is an Italian prospective multicentre study, involving a clinical and instrumental work-up to assess AC prevalence among patients ≥55 years old with an echocardiogram suggestive of AC (i.e. at least one echocardiographic red flag of AC in hypertrophic, non-dilated left ventricles with preserved ejection fraction). The study was registered at ClinicalTrials.gov (NCT04738266). Overall, 381 patients with an echocardiogram suggestive of AC were identified among a cohort of 5315 screened subjects, and 217 patients completed the investigations. A final diagnosis of AC was made in 62 patients with an estimated prevalence of 29% (95% confidence interval 23%-35%). Transthyretin-related AC (ATTR-AC) was diagnosed in 51 and light chain-related AC (AL-AC) in 11 patients. Either apical sparing or a combination of ≥2 other echocardiographic red flags, excluding interatrial septum thickness, provided a diagnostic accuracy >70%., Conclusion: In a cohort of consecutive adults with echocardiographic findings suggestive of AC and preserved left ventricular ejection fraction, the prevalence of AC (either ATTR or AL) was 29%. Easily available echocardiographic red flags, when combined together, demonstrated good diagnostic accuracy., (© 2022 European Society of Cardiology.)
