The Use of Barbed Sutures in Total Hip Arthroplasty: A Systematic Review on Clinical-Surgical Outcomes, Costs, and Complications.

PURPOSE: Total hip arthroplasty is among the most successful procedures in orthopaedic surgery. As the total number of total hip arthroplasties is constantly rising and it is expected to further increase, efforts oriented to optimise surgical pathways are investigated, aiming to reduce complications and diminish costs. The wound suturing phase is one of the steps that may be addressed. Barbed sutures have proved to reduce surgical times and enhance suture stability, then reducing wound-related complications in many surgical fields. The evidence on the use of this technology in total hip arthroplasty is still sparse, and its effect on patient outcomes and costs must still be clarified. METHODS: A systematic search of studies published from 1 January 2000 to 1 March 2023 was performed. Two authors independently reviewed the literature available in eight electronic databases to identify papers eligible for inclusion. RESULTS: A total of nine studies investigating 6959 procedures on 6959 patients were included in the final analysis. Five studies were randomised controlled trials, and the overall quality of studies ranged from moderate to high. The mean age of patients ranged from 43.8 to 70 years. BMI ranged from 25 to 31.9 kg/m2. The mean follow-up of studies ranged from 3 to 6 months. CONCLUSIONS: Evidence included in the systematic review suggested that the use of barbed sutures is associated with lower suturing times, complication rates, and overall costs when compared to the use of traditional suturing techniques. LEVEL OF EVIDENCE: II, systematic review of level I and II studies.

Endocrine-metabolic assessment checklist for cancer patients treated with immunotherapy: A proposal by the Italian Association of Medical Oncology (AIOM), Italian Association of Medical Diabetologists (AMD), Italian Society of Diabetology (SID), Italian Society of Endocrinology (SIE) and Italian Society of Pharmacology (SIF) multidisciplinary group.

Immunotherapy with immune checkpoint inhibitors (ICI) is increasingly employed in oncology. National and international endocrine and oncologic scientific societies have provided guidelines for the management of endocrine immune-related adverse events. However, guidelines recommendations differ according to the specific filed, particularly pertaining to recommendations for the timing of endocrine testing. In this position paper, a panel of experts of the Italian Association of Medical Oncology (AIOM), Italian Association of Medical Diabetologists (AMD), Italian Society of Diabetology (SID), Italian Society of Endocrinology (SIE), and Italian Society of Pharmacology (SIF) offers a critical multidisciplinary consensus for a clear, simple, useful, and easily applicable endocrine-metabolic assessment checklist for cancer patients on immunotherapy.

Arrhythmic Mitral Valve Prolapse and Sports Activity: Pathophysiology, Risk Stratification, and Sports Eligibility Assessment.

Although mitral valve prolapse (MVP) is the most prevalent valvular abnormality in Western countries and generally carries a good prognosis, a small subset of patients is exposed to a significant risk of malignant ventricular arrhythmias (VAs) and sudden cardiac death (SCD), the so-called arrhythmic MVP (AMVP) syndrome. Recent work has emphasized phenotypical risk features of severe AMVP and clarified its pathophysiology. However, the appropriate assessment and risk stratification of patients with suspected AMVP remains a clinical conundrum, with the possibility of both overestimating and underestimating the risk of malignant VAs, with the inappropriate use of advanced imaging and invasive electrophysiology study on one hand, and the catastrophic occurrence of SCD on the other. Furthermore, the sports eligibility assessment of athletes with AMVP remains ill defined, especially in the grey zone of intermediate arrhythmic risk. The definition, epidemiology, pathophysiology, risk stratification, and treatment of AMVP are covered in the present review. Considering recent guidelines and expert consensus statements, we propose a comprehensive pathway to facilitate appropriate counseling concerning the practice of competitive/leisure-time sports, envisioning shared decision making and the multidisciplinary "sports heart team" evaluation of borderline cases. Our final aim is to encourage an active lifestyle without compromising patients' safety.

Implementation of circulating tumour DNA multi-target mutation testing in plasma: a perspective from an external quality assessment providers' survey.

Demand for large-scale tumour profiling across cancer types has increased in recent years, driven by the emergence of targeted drug therapies. Analysing alternations in plasma circulating tumour DNA (ctDNA) for cancer detection can improve survival; ctDNA testing is recommended when tumour tissue is unavailable. An online survey of molecular pathology testing was circulated by six external quality assessment members of IQN Path to registered laboratories and all IQN Path collaborative corporate members. Data from 275 laboratories across 45 countries were collected; 245 (89%) perform molecular pathology testing, including 177 (64%) which perform plasma ctDNA diagnostic service testing. The most common tests were next-generation sequencing-based (n = 113). Genes with known stratified treatment options, including KRAS (n = 97), NRAS (n = 84), and EGFR (n = 130), were common targets. The uptake of ctDNA plasma testing and plans to implement further testing demonstrates the importance of support from a well-designed EQA scheme.

The long-term effects of hospitalization on health care expenditures: An empirical analysis for the young-old population in Lombardy.

As the burden of acute care on government budgets is mounting in many countries, documenting the evolution of health costs following patients' hospital admission is essential for assessing overall hospital-related costs. In this paper, we investigate the short- and long-term effects of hospitalization on different types of health care expenditures. We specify and estimate a dynamic DID model using register data of the entire population of individuals aged 50-70 residing in Milan, Italy, over the period 2008-2017. We find evidence of a large and persistent effect of hospitalization on total health care expenditures, with future medical expenses mostly accounted for by inpatient care. Considering all health treatments, the overall effect is sizable and is about twice the cost of a single hospital admission. We show that chronically ill and disabled individuals require greater post-discharge medical assistance, especially for inpatient care, and that cardiovascular and oncological diseases together account for more than half of expenditures on future hospitalizations. Alternative out-of-hospital management practices are discussed as a post-admission cost-containment measure.

Microelectrode voltage mapping for substrate assessment in catheter ablation of ventricular tachycardia: A dual-center experience.

INTRODUCTION: The assessment of the ventricular myocardial substrate critically depends on the size of mapping electrodes, their orientation with respect to wavefront propagation, and interelectrode distance. We conducted a dual-center study to evaluate the impact of microelectrode mapping in patients undergoing catheter ablation (CA) of ventricular tachycardia (VT). METHODS: We included 21 consecutive patients (median age, 68 [12], 95% male) with structural heart disease undergoing CA for electrical storm (n = 14) or recurrent VT (n = 7) using the QDOT Micro catheter and a multipolar catheter (PentaRay, n = 9). The associations of peak-to-peak maximum standard bipolar (BVc ) and minibipolar (PentaRay, BVp ) with microbipolar (BVµMax ) voltages were respectively tested in sinus rhythm with mixed effect models. Furthermore, we compared the features of standard bipolar (BE) and microbipolar (µBE) electrograms in sinus rhythm at sites of termination with radiofrequency energy. RESULTS: BVµMax was moderately associated with both BVc (ß = .85, p < .01) and BVp (ß = .56, p < .01). BVµMax was 0.98 (95% CI: 0.93-1.04, p < .01) mV larger than corresponding BVc , and 0.27 (95% CI: 0.16-0.37, p < .01) mV larger than matching BVp in sinus rhythm, with higher percentage differences in low voltage regions, leading to smaller endocardial dense scar (2.3 [2.7] vs. 12.1 [17] cm2 , p < .01) and border zone (3.2 [7.4] vs. 4.8 [20.1] cm2 , p = .03) regions in microbipolar maps compared to standard bipolar maps. Late potentials areas were nonsignificantly greater in microelectrode maps, compared to standard electrode maps. At sites of VT termination (n = 14), µBE were of higher amplitude (0.9 [0.8] vs. 0.4 [0.2] mV, p < .01), longer duration (117 [66] vs. 74 [38] ms, p < .01), and with greater number of peaks (4 [2] vs. 2 [1], p < .01) in sinus rhythm compared to BE. CONCLUSION: microelectrode mapping is more sensitive than standard bipolar mapping in the identification of viable myocytes in SR, and may facilitate recognition of targets for CA.

First SARS-CoV-2 vaccine booster and influenza vaccination: risk assessment of COVID-19 hospitalisation and death.

BACKGROUND: the influenza and SARS-CoV-2 viruses share a common respiratory symptomatology and transmission mode. COVID-19 and influenza R0 overlapped in the first epidemic wave. In autumn 2021-winter 2022, the influenza epidemic had a delayed onset compared to pre-COVID-19 years and lower incidence rates than in the pre-pandemic period. The SARS-CoV-2 and influenza vaccination campaign overlapped in 2021-2022. OBJECTIVES: to evaluate in the SARS-CoV-2 vaccinated cohort the effect of different timing of influenza vaccination on hospitalisations for COVID-19 and overall mortality. DESIGN: prospective cohort study. SETTING AND PARTICIPANTS: subjects aged 65 years or older who were administered the first booster dose of SARS-COV-2 vaccine between 01.10.2021 and 01.03.2022. Based on the date of influenza vaccination, subjects were divided into the following 4 different mutually exclusive groups: 1. two vaccinations in the same vaccination session; 2. influenza vaccination following SARS-CoV-2 vaccination; 3. influenza vaccination preceding SARS-CoV-2 vaccination; 4. no influenza vaccination. Using Cox regression models, hazard ratio (HR) and corresponding 95% confidence intervals (95% CI) of hospitalisation and death were estimated for the influenza-vaccinated subjects compared to influenza-unvaccinated subjects. MAIN OUTCOME MEASURES: ordinary hospital admissions for COVID-19 and general mortality. RESULTS: the cohort included 618,964 subjects: 16.3% received two vaccinations in the same vaccination session, 8.5% received the influenza vaccination after SARS-CoV-2 vaccination, 33.9% received it before and 41.1% did not receive an influenza vaccination. Those vaccinated against both SARS-CoV-2 and influenza had a combined HR of 0.73 (0.62-0.86) of hospitalisation for COVID-19 and 0.55 (0.49-0.62) of overall mortality compared to those vaccinated against SARS-CoV-2 only. CONCLUSIONS: influenza vaccination combined with SARS-CoV-2 vaccination increases the protective effect against hospitalisations and overall mortality compared to SARS-CoV-2 vaccination alone. Both organisational and communication actions aimed to promote and encourage vaccination are required.

Indirect impact of the COVID-19 pandemic and its containment measures on social inequalities in hospital utilisation in Italy.

BACKGROUND: The pandemic may undermine the equity of access to and utilisation of health services for conditions other than COVID-19. The objective of the study is to evaluate the indirect impact of COVID-19 and lockdown measures on sociodemographic inequalities in healthcare utilisation in seven Italian areas. METHODS: In this multicentre retrospective study, we evaluated whether COVID-19 modified the association between educational level or deprivation and indicators of hospital utilisation and quality of care. We also assessed variations in gradients by sex and age class. We estimated age-standardised rates and prevalence and their relative per cent changes comparing pandemic (2020) and pre-pandemic (2018-2019) periods, and the Relative Index of Inequalities (RIIs) fitting multivariable Poisson models with an interaction between socioeconomic position and period. RESULTS: Compared with 2018-2019, hospital utilisation and, to a lesser extent, timeliness of procedures indicators fell during the first months of 2020. Larger declines were registered among women, the elderly and the low educated resulting in a shrinkage (or widening if RII <1) of the educational gradients for most of the indicators. Timeliness of procedures indicators did not show any educational gradient neither before nor during the pandemic. Inequalities by deprivation were nuanced and did not substantially change in 2020. CONCLUSIONS: The socially patterned reduction of hospital utilisation may lead to a potential exacerbation of health inequalities among groups who were already vulnerable before the pandemic. The healthcare service can contribute to contrast health disparities worsened by COVID-19 through more efficient communication and locally appropriate interventions.

Boosters and time from the last anti-COVID-19 vaccine dose: lead public health choices by real-time epidemiological assessment.

BACKGROUND: the levels of anti-SARS-CoV-2 antibodies after the second vaccine dose decline in the following months; the administration of an additional vaccine dose (booster) is able to restore the immune system in the short period significantly reducing the risk of a severe disease. In the winter of 2021, a new particularly infectious variant caused the urgent need to increase the coverage of the booster dose. OBJECTIVES: to present, using real data, an evaluation of the efficacy of the booster dose in reducing the severe disease of SARS-CoV-2 infection in terms of hospital admissions, intensive care and death from all causes. DESIGN: descriptive study of vaccine adherence; associative study of the factors linked with adherence of vaccination and COVID-19 symptoms; associative study of vaccine effectiveness against hospital admission and mortality. SETTING AND PARTICIPANTS: population-based study in the Milan and Lodi provinces (Lombardy Region, Northern Italy) with subjects aged >=19 years alive at 01.10.2021, not residing in a nursery home, followed up to 31.12.2021. MAIN OUTCOME MEASURES: COVID-19 symptoms, hospitalization for COVID-19, intensive care hospitalization, and all-cause mortality in the period 01.10.2021-31.12.2021. RESULTS: the cohort included 2,936,193 patients at 01.10.2021: at the end of the follow-up period (31.12.2021), 378,616 (12.9%) had no vaccine, 128,879 (4.3%) had only 1 dose, 412,227 (14.0%) had a 2nd dose given since less than 4 months, 725. 806 (25%) had a 2nd dose given since 4-7 months, 74,152 (2.5%) had a 2nd dose given since 7+ months, 62,614 (2.1%) had a 2nd dose and have had the disease, and 1,153,899 (39.3%) received the booster. In the study period (01.10.2021-31.12.2021), characterized by a very high prevalence of the omicron variant, 121,620 cases (antigenic/molecular buffer positive), 3,661 hospitalizations for COVID-19, 162 ICU hospitalizations, and 7,508 deaths from all causes were identified. Compared to unvaccinated people, subjects who had the booster dose had half the risk of being symptomatic, in particular for asthenia, muscle pain, and dyspnoea which are the most commons COVID-19 symptoms. In comparison with the subjects who had the booster dose, the unvaccinated had a 10-fold risk of hospitalization for COVID-19, a 9-fold risk of intensive care, and a 3-fold risk of dying. CONCLUSIONS: this work highlights the vaccination efficacy in reducing serious adverse events for those who undergo the booster and the need to implement specific engagement policies to bring to a booster those who had taken the second dose since the longest time.

Next generation diagnostic algorithm in non-small cell lung cancer predictive molecular pathology: The KWAY Italian multicenter cost evaluation study.

AIMS: The KWAY project aims to investigate the economic sustainability of the up-front NGS technologies adoption in the analysis of clinically relevant molecular alterations in NSCLC patients. METHODS: The diagnostic workflow and the related sustained costs of five Italian referral centers were assessed in four different evolving scenarios were analyzed. For each scenario, two alternative testing strategies were evaluated: the Maximized Standard strategy and the Maximized NGS strategy. RESULTS: For each center, the robustness of obtained results was verified through a deterministic sensitivity analysis, observing the variation of total costs based on a variation of ±20 % of the input parameters and ensuring that results would present a consistent behavior compared to the original ones. CONCLUSIONS: our project, highlighted that the adoption of NGS allows to save personnel time dedicated to testing activities and to reduce the overall cost of testing per patient.

Intraprocedural PRAETORIAN score for early assessment of S-ICD implantation: A proof-of-concept study.

INTRODUCTION: The PRAETORIAN score (PS) was developed to assess the implant position and predict defibrillation success of the subcutaneous implantable cardioverter defibrillators (S-ICD). The main critique moved to the routine use of PS has been its postprocedural timing, that limits its usefulness on procedure guidance. The aim of this proof-of-concept study was to assess the feasibility of an intraprocedural use of PS. METHODS: Forty consecutive patients undergoing S-ICD implantation were enrolled. Intraprocedural PS (IP-PS) obtained with fluoroscopy before closure of the pocket and postprocedural PS (PP-PS) obtained with two-views chest X-ray were compared. Intraprocedural data and PS were compared with the historic cohorts of the involved institutions. RESULTS: When assessing IP-PS and PP-PS, a complete overall agreement was observed (100%, 1.00-κ; p < .001). When assessing a per-step agreement, a very high-degree of concordance in evaluating Step 1 of the PS was observed (95%, 0.81-κ; p < .001). A complete agreement in Step 2-3 (100%, 1.00-κ; p < .001) of the PS was reported. In comparison with our historical cohort, procedural time in the IP-PS cohort did not increase (45 [41-52] vs. 45 [39-49] min; p = .351) while the expected increase in fluoroscopy time resulted scarce (15 [10-15] s). CONCLUSION: An IP-PS can be reliably obtained using fluoroscopy guidance during S-ICD implantation, without a significant increase in procedural duration and may serve as guidance for implanting physicians, to avoid postprocedural S-ICD repositioning, leading to patient discomfort and significantly enhancing infective risks. IP-PS showed a very high agreement with the PP-PS obtained from two-views chest X-ray.

Clinical features, disease progression, and use of healthcare resources in a large sample of 866 patients from 24 headache centers: A real-life perspective from the Italian chROnic migraiNe (IRON) project.

OBJECTIVE: To develop a dedicated Italian chronic migraine (CM) database (IRON project) to overcome disease misconceptions, improve clinical administration, reduce patients' burden, and rationalize economic resource allotment. BACKGROUND: Proper CM management requires a comprehensive appraisal of its full clinical, social, and economic complexity. METHODS: In this cross-sectional study, CM patients were screened in 24 certified headache centers with face-to-face interviews. Information on sociodemographic factors, medical history, characteristics of CM, and of prior episodic migraine (EM), and healthcare resource use was gathered using a semistructured web-based questionnaire. RESULTS: A total of 866 CM patients were enrolled. CM started ~20 years after EM onset (age at EM onset 17.4 ± 9.1 vs. age at CM onset 35.3 ± 12.5 [mean ± SD]). CM prophylaxis, used by 430/866 (49.6%) of the patients, was often ineffective, not tolerated, and prematurely discontinued. Medications and diagnostic workup, frequently inappropriate, were mostly subsidized by the Italian national health service. CM patients with ≥25 headache days/month revealed substantial clinical differences and heavier disability and economic burden compared with those with <25 headache days/month. CONCLUSIONS: CM is a heterogeneous headache disorder deserving more in-depth clinical characterization, sharper diagnostic criteria, and tailored treatments. CM registries are expected to improve clinical management, resulting in increased disease awareness, better healthcare resource allocation, and reduced economic burden.

Assessing the Impact of Individual Characteristics and Neighborhood Socioeconomic Status During the COVID-19 Pandemic in the Provinces of Milan and Lodi.

Social inequalities in health are known to be influenced by the socioeconomic status of the territory in which people live. In the context of the ongoing coronavirus disease 2019 (COVID-19) pandemic, this study is aimed at assessing the role of 5 area-level indicators in shaping the risk of contagion in the provinces of Milan and Lodi (Lombardy, Italy), namely: educational disadvantage, unemployment, housing crowding, mobility, and population density. The study area includes the municipalities at the origin of the first Italian epidemic outbreak. Data on COVID-19 patients from the Integrated Datawarehouse for COVID Analysis in Milan were used and matched with aggregate-level data from the National Institute of Statistics Italy (Istat). Multilevel logistic regression models were used to estimate the association between the census block-level predictors and COVID-19 infection, independently of age, sex, country of birth, and preexisting health conditions. All the variables were significantly associated with the outcome, with different effects before and after the lockdown and according to the province of residence. This suggests a pattern of socioeconomic inequalities in the outbreak, which should be taken into account in the eventuality of future epidemics to contain their spread and its related disparities.

The Economic Impact of Rectal Cancer: A Population-Based Study in Italy

Costs of cancer care are increasing worldwide, and sustainability of cancer burden is critical. In this study, the economic impact of rectal cancer on the Italian healthcare system, measured as public healthcare expenditure related to investigation and treatment of rectal cancer patients is estimated. A cross-sectional cohort of 9358 rectal cancer patients is linked, on an individual basis, to claims associated to rectal cancer diagnosis and treatments. Costs refer mainly to years 2010-2011 and are estimated by phase of care, as healthcare needs vary along the care pathway: diagnostic procedures are mainly provided in the first year, surveillance procedures are addressed to chronically ill patients, and end-of-life procedures are given in the terminal status. Clinical approaches and corresponding costs are specific by cancer type and vary by phase of care, stage at diagnosis, and age. Surgery is undertaken by the great majority of patients. Thus, hospitalization is the main cost driver. The evidence produced can be used to improve planning and allocation of healthcare resources. In particular, early diagnosis of rectal cancer is a gain in healthcare budget. Policies raising spreading of and adherence to screening plans, above all when addressed to people living in Southern Italy, should be strongly encouraged.

Assessment of patients presenting with life-threatening ventricular arrhythmias and suspected myocarditis: The key role of endomyocardial biopsy.

BACKGROUND: Life-threatening ventricular tachyarrhythmias (VAs) represent a significant cause of death in myocarditis. OBJECTIVE: The purpose of this study was to identify predictors of sustained VAs in patients with myocarditis and ventricular phenotype diagnosed by workflow including endomyocardial biopsy (EMB) guided by 3D electroanatomic mapping (3D-EAM). METHODS: We prospectively enrolled patients with suspected myocarditis and VAs, undergoing cardiac magnetic resonance imaging, coronary angiography, 3D-EAM, and EMB guided by 3D-EAM. At follow-up, sustained VAs were detected by device interrogation and 24-hour electrocardiographic Holter monitoring. RESULTS: We enrolled 54 consecutive patients (mean age 41 ± 14 years; 32(59%) men) with normal ventricular function; left ventricular and right ventricular (RV) late gadolinium enhancement was present, respectively, in 21 (46%) and 6 (13%) of the 46 patients who underwent cardiac magnetic resonance. In 31 patients, the histological diagnosis was myocarditis, while in 14 patients, focal replacement myocardial fibrosis (FRMF); in 9 patients, specimens were inadequate (diagnostic yield of EMB 83%). 3D-EAM showed a larger endocardial scar area for both ventricles in myocarditis than in FRMF (RV bipolar mean scar area 22 ± 16 cm2 vs 3 ± 2 cm2; P = .02; left ventricular bipolar mean scar area 13 ± 5 cm2 vs 4 ± 2 cm2; P = .02, respectively). At a follow-up of 21 months, freedom from sustained VAs was 58% in myocarditis and 92% in FRMF (log-rank, P = .008). Histological diagnosis of myocarditis and RV endocardial scar were independent predictors of sustained VAs (P = .02 for both). CONCLUSION: Our data highlight the need for 3D-EAM-guided EMB in apparently healthy young patients with suspected myocarditis and VAs.

Assessment and Comparison of Two Serological Approaches for the Surveillance of Health Workers Exposed to SARS-CoV-2.

BACKGROUND AND AIM: The aim of the present study was to assess the diagnostic performance of an LFA compared with an ELISA test in a cohort of HWs operating in a COVID-19 unit of a teaching hospital in southern Italy. METHODS: We performed an observational, prospective, interventional study including 65 COVID-19 unit personnel. On a total of 196 serum samples (at least 2 serum samples for each HW), LFA and ELISA tests for SARS-COV-2 IgG and IgM were performed. Also, 32 serum samples of SARS-CoV-2 RNA positive patients at least 21 days before sampling, and 30 serum samples of patients obtained up to November 2019, before COVID-19 outbreak in China, were used as positive and negative controls, respectively. FINDINGS: Of the 65 HWs enrolled, 6 were positive in LFA; overall, of the 196 serum samples, 20 were positive in LFA. All ELISA tests performed on serum samples collected from HWs were negative. The specificity of LFAs was 90.77% considering the 65 HWs and 89.80% considering all the 196 health workers serum samples analyzed. Considering the data on HWs, ELISA test for SARS-COV-2 antibodies showed a specificity of 100%, including all the 196 serum samples collected, and 100% including the 65 HWs. The ELISA and LFAs performed after 21 days last COVID-19 patient was discharged were all negative. CONCLUSION: LFAs compared to ELISA tests result in less specificity, considering COVID-19 negative personnel and patients. Thus, LFAs seem to be not adequate in the active surveillance of HWs.

Impact of BMI on Preoperative Axillary Ultrasound Assessment in Patients With Early Breast Cancer.

BACKGROUND: The accuracy of axillary ultrasound (AUS) with fine-needle aspiration with varying patient body mass index (BMI) is still unclear. The aim of our study was to evaluate whether the US features of axillary lymph nodes changes with BMI of patients. PATIENTS AND METHODS: A retrospective review was performed involving 144 out of 270 patients with early breast cancer who underwent breast surgery with sentinel lymph node biopsy. Diagnostic efficacy of AUS in preoperative axillary nodal staging was assessed in relation to BMI. RESULTS: Negative predictive values of AUS for the overweight and obese groups were statistically significantly lower compared to the normal/underweight group (p=0.02 and p=0.003, respectively). Additionally, Spearman's correlation coefficient R between BMI and positive sentinel lymph node biopsy was 0.257, suggesting a significantly positive linear relationship between the two variables in the cohort overall. CONCLUSION: Our results demonstrate how in our cohort the negative predictive value of AUS was significantly influenced by adipose tissue and that the selection of the most suitable instrumental diagnostic technique might contribute to improving heterogeneous results.

Burden, risk assessment, surveillance and management of SARS-CoV-2 infection in health workers: a scoping review.

BACKGROUND: Health workers (HWs) are at increased risk for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection and a possible source of nosocomial transmission clusters. Despite the increased risk, the best surveillance strategy and management of exposed HWs are not yet well known. The aim of this review was to summarize and critically analyze the existing evidence related to this topic in order to support public health strategies aimed at protecting HWs in the hospital setting. MAIN TEXT: A comprehensive computerized literature research from 1 January 2020 up to 22 May 2020 was made to identify studies analyzing the burden of infection, risk assessment, surveillance and management of HWs exposed to SARS-CoV-2. Among 1623 citation identified using MEDLINE, Embase, Google Scholar and manual search, we included 43 studies, 14 webpages and 5 ongoing trials. Health workers have a high risk of acquiring infection while caring for coronavirus disease 2019 (COVID-19) patients. In particular, some types exposures and their duration, as well as the inadequate or non-use of personal protective equipment (PPE) are associated with increased infection risk. Strict infection prevention and control procedures (IPC), adequate training programs on the appropriate use of PPE and close monitoring of HWs with symptom surveillance and testing are essential to significantly reduce the risk. At the moment there is not enough evidence to provide precise indications regarding pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP). CONCLUSIONS: During the spread of COVID-19 outbreak, numerous published papers investigated the epidemiology, risk assessment and prevention and control of SARS-CoV-2. However, more high-quality studies are needed to provide valid recommendations for better management and for the clinical and microbiological surveillance of healthcare personnel.

Procedural sedation for direct current cardioversion: a feasibility study between two management strategies in the emergency department.

BACKGROUND: A cardiologist-only approach to procedural sedation with midazolam in the setting of elective cardioversion (DCC) for AF has already been proven as safe as sedation with propofol and anaesthesiologist assistance. No data exist regarding the safety of such a strategy during emergency procedures. The aim of this study is to compare the feasibility of sedation with midazolam, administered by a cardiologist, to an anaesthesiologist-assisted protocol with propofol in emergency DCC. METHODS: Single centre, prospective, open blinded, randomized study including all consecutive patients admitted to the Emergency Department requiring urgent or emergency DCC. Patients were randomized in a 1:1 fashion to either propofol or midazolam treatment arm. Patients in the midazolam group were managed by the cardiologist only, while patients treated with propofol group underwent DCC with anaesthesiologist assistance. RESULTS: Sixty-nine patients were enrolled and split into two groups. Eighteen patients (26.1%) experienced peri-procedural adverse events (bradycardia, severe hypotension and severe hypoxia), which were similar between the two groups and all successfully managed by the cardiologist. No deaths, stroke or need for invasive ventilation were registered. Patients treated with propofol experienced a greater decrease in systolic and diastolic blood pressure when compared with those treated with midazolam. As the procedure was shorter when midazolam was used, the median cost of urgent/emergency DCC with midazolam was estimated to be 129.0 € (1st-3rd quartiles 114.6-151.6) and 195.6 € (1st-3rd quartiles 147.3-726.7) with propofol (p < .001). CONCLUSIONS: Procedural sedation with midazolam given by the cardiologist alone was feasible, well-tolerated and cost-effective in emergency DCC.

Multidimensional assessment of the effects of erenumab in chronic migraine patients with previous unsuccessful preventive treatments: a comprehensive real-world experience.

BACKGROUND: erenumab was safe and effective in clinical trials for the prevention of migraine. However, real-life data are still lacking. Here we report the clinical experience from an Italian real-world setting using erenumab in patients with chronic migraine experiencing previous unsuccessful preventive treatments. METHODS: Seventy patients with chronic migraine and failure to ≥4 migraine preventive medication classes initially received monthly erenumab 70 mg s.c. Patients without a clinically meaningful improvement, considered as a > 30% reduction in headache days per month, after ≥3 months of therapy switched to monthly erenumab 140 mg. At the first administration and after 3 and 6 months, patients underwent extensive interviews to assess clinical parameters of disease severity and migraine-related disability and impact, and validated questionnaires to explore depression/anxiety, sleep, and quality of life (QoL). Finally, the Pain Catastrophizing Scale, Allodynia Symptom Checklist-12 and MIGraine attacks-Subjective COGnitive impairments scale (MIG-SCOG) were administered. RESULTS: 70% of patients were "responders" after the third administration of erenumab 70 mg, whereas 30% switched to erenumab 140 mg; 29% (6 pts) responded after the sixth administration. The headache-day frequency was reduced from 21.1 ± 0.7 to 11.4 ± 0.9 days after the third administration (p < 0.001) and to 8.9 ± 0.7 days after the sixth administration (p < 0.001). 53% and 70% of patients, respectively, showed a reduction of ≥50% of headache days/month after the third and the sixth administrations. Also improved were headache pain severity, migraine-related disability, and impact on daily living, QoL, pain catastrophizing and allodynia (all p < 0.001), quality of sleep, symptoms of depression or anxiety (p < 0.05) but not MIG-SCOG. There were no new adverse event signals. CONCLUSION: These real-world data support monthly erenumab 70 or 140 mg s.c. as a safe and effective preventive treatment to reduce headache frequency and severity in chronic migraine patients experiencing previous unsuccessful preventive treatments.
