La moderna organizzazione del mondo del lavoro, in modo particolare per quel che riguarda gli aspetti produttivi, si è andata negli anni profondamente modificando negli aspetti ergonomici con lo sviluppo di modifiche sia dell'organizzazione che dei tempi e ritmi di lavoro, nonché nell'attenzione dedicata al riconoscimento della possibile eziologia professionale delle malattie dell'apparato locomotore. Parallelamente in tutto il mondo occidentale si è assistito negli ultimi anni ad un sensibile aumento della denuncia di disturbi a carico dell'apparato muscolo- scheletrico nei lavoratori, con un meccanismo patogenetico spesso riconoscibile in un sovraccarico biomeccanico del distretto interessato in assenza di eventi traumatici. Viene presentato un caso clinico di probabile patologia da sovraccarico biomeccanico esitata in "spalla pseudo-paralitica" con esiti di lesione della cuffia dei rotatori in una lavoratrice di 52 anni, con anamnesi positiva per tali rischi professionali da ricondurre alla fustellatura di carta e cartone. La valutazione biomeccanica della mansione in oggetto rileva il possibile sviluppo di sofferenza metabolica della fibrocellula muscolare, dovuta al susseguirsi reiterato di contrazioni antagoniste di tipo concentrico ed eccentrico, che, unitamente all'atteggiamento obbligato in intrarotazione del braccio, favorisce l'impatto tra testa omerale e volta acromiale. Le indagini clinico-strumentali evidenziavano lesioni tendinosiche complesse e soluzioni di continuo su base traumatico degenerativa a carico della cuffia dei rotatori bilateralmente con conseguente sintomatologia algica e limitazione funzionale. Alla luce di queste considerazioni e della storia lavorativa, le lesioni documentate appaiono ampiamente riconducibili alla mansione esercitata e suggeriscono l'importanza di una valutazione dei rischi che tenga conto, in caso di movimenti complessi, dell'impegno segmentario dei singoli muscoli e non solo dell'asse di movimento, nonché del ruolo svolto dalla postura nei confronti del sovraccarico funzionale.

Cardiovascular diseases (CVDs) remain a major global health challenge, leading to significant morbidity and mortality while straining healthcare systems. Despite progress in medical treatments for CVDs, their increasing prevalence calls for a shift towards more effective prevention strategies. Traditional preventive approaches have centered around lifestyle changes, risk factors management, and medication. However, the integration of imaging methods offers a novel dimension in early disease detection, risk assessment, and ongoing monitoring of at-risk individuals. Imaging techniques such as supra-aortic trunks ultrasound, echocardiography, cardiac magnetic resonance, and coronary computed tomography angiography have broadened our understanding of the anatomical and functional aspects of cardiovascular health. These techniques enable personalized prevention strategies by providing detailed insights into the cardiac and vascular states, significantly enhancing our ability to combat the progression of CVDs. This review focuses on amalgamating current findings, technological innovations, and the impact of integrating advanced imaging modalities into cardiovascular risk prevention, aiming to offer a comprehensive perspective on their potential to transform preventive cardiology.

Heart failure (HF) is a leading cause of morbidity worldwide, imposing a significant burden on deaths, hospitalizations, and health costs. Anticipating patients' deterioration is a cornerstone of HF treatment: preventing congestion and end organ damage while titrating HF therapies is the aim of the majority of clinical trials. Anyway, real-life medicine struggles with resource optimization, often reducing the chances of providing a patient-tailored follow-up. Telehealth holds the potential to drive substantial qualitative improvement in clinical practice through the development of patient-centered care, facilitating resource optimization, leading to decreased outpatient visits, hospitalizations, and lengths of hospital stays. Different technologies are rising to offer the best possible care to many subsets of patients, facing any stage of HF, and challenging extreme scenarios such as heart transplantation and ventricular assist devices. This article aims to thoroughly examine the potential advantages and obstacles presented by both existing and emerging telehealth technologies, including artificial intelligence.

Scuba diving is one of the most common and practised water sport activities in Genoa, especially in the more recent years. Although scuba diving is generally considered a safe activity, this does not exclude the possibility of serious or fatal accidents from happening. This retrospective study investigates the case history of deaths resulting from diving accidents recorded by the Municipal Morgue of Genoa over a period of 53 years, specifically from 1968 to 2021. Of the total 52 deaths covered by the study, 48 were male with an age range of 16-71 years. In 25 of these subjects, pre-existing pathological conditions of a cardiovascular nature, not recognised at the time of death, were reported. Out of the total deaths studied, 9 subjects died following a diving accident related to free diving, while 43 subjects died from scuba or rebreather diving. Among the latter subjects, the cause of death was attributed to drowning in 17 cases, arterial gas embolism (AGE) from pulmonary over-distension in 11 cases, cardio-circulatory arrest (CA) favoured by pre-existing and non-existing heart disease known prior to the death in 10 cases, decompression sickness (DCS) in 2 cases, a combination of DCS and AGE in 2 cases and oxygen intoxication in 1 case. Twelve of the fatal accidents occurred in the marine area near the village of Arenzano, where the shipwreck of the oil tanker, the "Haven", sank in 1991 and is today the largest shipwreck explored by divers in the Mediterranean Sea. In all cases of diving deaths, a multi-disciplinary approach is important: in particular, the role of the forensic pathologist is essential in order to accurately reconstruct the dynamics of the accident, thus identifying the predisposing or triggering factors that led to death, and defining the cause of it., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable heart muscle disorder with fibro-fatty replacement that involves the right ventricle and in the advanced phases could become biventricular. Takotsubo syndrome (TTS) is characterized by reversible systolic dysfunction occurring after a stressful event and independent of the underlying coronary artery disease. A 70-year-old female with family history of sudden cardiac death and a previous diagnosis of biventricular ARVC presented to the emergency department after experiencing chest pain and elevation of myocardial enzymes. The ECG showed sinus bradycardia and negative T-waves from V1-V3. Coronary arteries were free from stenosing atheromatous lesions at coronary angiography. Transthoracic echocardiography showed severe biventricular dysfunction due to left ventricular apical/peri-apical akinesis with apical ballooning pattern. Cardiac magnetic resonance confirmed the presence of transmural biventricular edema in the mid-apical segments in T2 weighted sequences involving both ventricles along with fibro-fatty replacement in post-contrast sequences. At discharge, a cardioverter-defibrillator was implanted. This case report shows that TTS diagnosis is challenging for the clinician due to the presence of structural cardiomyopathy with biventricular involvement. Second-line imaging modalities could be useful to identify the presence of myocardial edema and to recognize those conditions associated with poor prognosis.

Healthcare-related SARS-CoV-2 infection is an issue of particular concern during the pandemic. It has important repercussions on the National Health System, which represents a source of medical-legal health disputes. In the healthcare context, there are reports of negative screening at hospital admission (via nasopharyngeal swabs) and subsequent diagnosis of SARS-CoV-2 infection during hospitalization. Such cases cannot be considered a priori of healthcare-related infections but require extensive in-depth evaluation. In this study, we propose an empirical classification to frame cases of SARS-CoV-2 infection diagnosed in the hospital (first negative admission swab, with subsequent positive test during hospitalization). The classification is based on five categories: nosocomial, probably nosocomial, indeterminate, probably community, and community cases. We analyzed patients who died after testing positive for SARS-CoV-2 during hospitalization (with initial negative screening) in the largest hospital in Northwest Italy from February 2020 to 31 December 2021. A total of 383 cases were tracked and are listed as follows: 41 cases (11%) were classified as nosocomial (i.e., 3.2% of COVID-19 deaths). In contrast, 71 cases (19%) were classified as probably nosocomial, 69 (18%) were indeterminate (i.e., the clinical, radiological, and laboratory characteristics did not provide information on the genesis of the infection), 166 (43%) were classified as probably community cases, and 36 (9%) were defined as community cases. Deceased patients with nosocomial SARS-CoV-2 infection constituted the following: 3.23% (41/1266) with respect to the total number of COVID-19 deaths, 1.1% (41/3789) with respect to those who entered the hospital with a negative swab and 0.82% (41/4672) with respect to the total of deaths from any cause of death. In this paper we discuss the topic and issues of nosocomial COVID-19 in hospitalized patients and address the medicolegal implications.

Background: Long-term sequelae, called Long-COVID (LC), may occur after SARS-CoV-2 infection, with unexplained dyspnoea as the most common symptom. The breathing pattern (BP) analysis, by means of the ratio of the inspiratory time (TI) during the tidal volume (VT) to the total breath duration (TI/TTOT) and by the VT/TI ratio, could further elucidate the underlying mechanisms of the unexplained dyspnoea in LC patients. Therefore, we analysed TI/TTOT and VT/TI at rest and during maximal exercise in LC patients with unexplained dyspnoea, compared to a control group. Methods: In this cross-sectional study, we enrolled LC patients with normal spirometry, who were required to perform a cardio-pulmonary exercise test (CPET) for unexplained dyspnoea, lasting at least 3 months after SARS-CoV-2 infection. As a control group, we recruited healthy age and sex-matched subjects (HS). All subjects performed spirometry and CPET, according to standardized procedures. Results: We found that 42 LC patients (23 females) had lower maximal exercise capacity, both in terms of maximal O2 uptake (VO2peak) and workload, compared to 40 HS (22 females) (p < 0.05). LC patients also showed significantly higher values of TI/TTOT at rest and at peak, and lower values in VT/TI at peak (p < 0.05). In LC patients, values of TI/TTOT at peak were significantly related to ∆PETCO2, i.e., the end-tidal pressure of CO2 at peak minus the one at rest (p < 0.05). When LC patients were categorized by the TI/TTOT 0.38 cut-off value, patients with TI/TTOT > 0.38 showed lower values in VO2peak and maximal workload, and greater values in the ventilation/CO2 linear relationship slope than patients with TI/TTOT ≤ 0.38 (p < 0.05). Conclusions: Our findings show that LC patients with unexplained dyspnoea have resting and exertional BP more prone to diaphragmatic fatigue, and less effective than controls. Pulmonary rehabilitation might be useful to revert this unpleasant condition.

A 62-year-old male patient with a history of atypical chest pain ad dyspnea presented to the emergency room during the COVID-19 pandemic. On admission, the ECG showed sinus rhythm with diphasic T waves in lead V2. A high resolution computed tomography revealed signs suggestive of pulmonary infarction and a subsequent nasopharyngeal swab for SARS-CoV-2 was positive. An ECG performed in the absence of symptoms showed persistence of diphasic T waves in lead V2. In the suspect of Wellens syndrome, a coronary angiography study was performed and showed a subocclusion of the proximal left anterior descending artery.

Several studies suggested that the acute phase of SARS-CoV-2 infection may be associated with a hypercoagulable state and increased risk for venous thromboembolism but the incidence of thrombotic complications in the late phase of the disease is currently unknown. The present article describes three cases of patients with SARS-CoV-2 pneumonia and late occurrence of pulmonary embolism. Case 1: a 57-year-old man diagnosed with pulmonary embolism and type B aortic dissection after 12 days from SARS-CoV-2 pneumonia. Laboratory panel at the time of pulmonary embolism showed no signs of ongoing inflammation but only an elevated D-dimer. Case 2: a 76-year-old man with a diagnosis of SARS-CoV-2 pneumonia followed by pulmonary embolism 20 days later, high-resolution computed tomography on that time showed a partial resolution of crazy paving consolidation. Case 3: a 77-year-old man with SARS-CoV-2 pneumonia who developed a venous thromboembolic event despite thromboprophylaxis with low molecular weight heparin. Also in this patients no markers of inflammation were present at the time of complication.The present cases raise the possibility that in SARS-CoV-2 infection the hypercoagulable state may persist over the active inflammation phase and cytokine storm. These findings suggest a role for medium-long term therapeutic anticoagulation started at the time of SARS-CoV-2 pneumonia diagnosis.

Background: Cardiac troponin (cTn) testing has reduced the likelihood of erroneous discharge of patients with acute coronary syndrome (ACS) from the emergency department (ED), but doubts remain about optimal clinical use. This study was planned for evaluating the predictive significance of cTn values between the limit of detection of the method and the 99th percentile in ED patients evaluated for suspected ACS., Methods: In this retrospective study all hospital records of patients admitted over a 6-month period to the ED and with at least one cTnI value comprised between the limit of detection (0.01 ng/mL) and the 99th percentile of the assay (0.05 ng/mL) were analyzed., Results: A total of 4,749 patients with cTnI value between 0.01-0.05 ng/mL were identified among 57,879 ED visits throughout the study period. Overall, 2,189 patients (46.1%) were discharged from the ED, 2,529 (53.25%) were admitted to the hospital and 31 (0.65%) died during ED stay. A total number of 289 patients out of 2,189 who were discharged (i.e., 13.2%) had additional ED visits within 30 days. Among these, 6 were diagnosed with ACS, representing 0.27% of patients discharged [negative predictive value (NPV) 0.997; 95% CI, 0.994-0.999] and 2.1% of those with second admission (NPV 0.979; 95% CI, 0.955-0.992). Only one of the 2,529 patients admitted to the hospital (i.e., 0.04%) developed an ACS during hospital stay., Conclusions: The results of our retrospective study suggest that the suitability of using a contemporary-sensitive cTnI immunoassay assay in the context of an appropriate protocol represents a safe and effective strategy for ruling in and ruling out ACS in patients presenting to the ED.

Objective: Soluble mesothelin-related peptide (SMRP) may be useful in the diagnosis and detection of early stage mesothelioma. We investigated the SMRP upfront predictive role for mesothelioma in asbestos-exposed workers., Methods: A total of 1,715 subjects underwent a first visit and were invited for a follow-up after 1 and 2 years, with a clinical examination and blood sampling. SMRP was measured by an ELISA assay., Results: Median SMRP at the first visit was 0.45 [interquartile range (IQR) i.e. 25th-75th percentile: 0.30-0.67 nmol/l]. In all, 1,676 subjects (97.8%) were followed up for a median period of 47.1 months. SMRP was measured at the first visit and at both follow-up visits in 1,536 subjects. At follow-up, 3 subjects were diagnosed with an epithelioid mesothelioma. In these cases, SMRP at the first visit ranged from 0.17 to 0.52 nmol/l. Malignant pleural mesothelioma was diagnosed 9-17 months after the last SMRP evaluation. No SMRP variation was observed during the follow-up. Other 61 miscellaneous cancers were diagnosed (median SMRP at first visit: 0.50 nmol/l, IQR: 0.34-0.71 nmol/l)., Conclusions: Our results did not support the usefulness of SMRP as an early marker for the detection of the disease for a time interval of 1 year., (© 2013 S.

Background: The screening of both healthcare workers and students attending teaching hospitals for latent tuberculosis infection (LTBI) is recommended in hospitals of many countries with a low-incidence of TB, including Italy, as a fundamental tool of tuberculosis (TB) control programs. The aim of the study was to estimate the prevalence of LTBI and evaluate the main risk-factors associated with this condition in a cohort of healthcare Italian students., Methods: In a cross-sectional study, performed between January and May 2012, 881 undergraduate students attending the Medical, Nursing, Pediatric Nursing and Midwifery Schools of the University of Genoa, trained at the IRCCS San Martino-IST Teaching Hospital of Genoa, were actively called to undergo the Tuberculin Skin Test (TST). All the TST positive cases were also tested with an Interferon-Gamma Release Assay (IGRA) to confirm the diagnosis of LTBI. A standardized questionnaire was collected for risk-assessment analysis., Results: Seven hundred and thirty-three (83.2%) subjects underwent TST testing. The prevalence of TST positives was 1.4%, and in 4 (0.5%) out of 10 TST positive cases LTBI diagnosis was confirmed by IGRA. No difference in the prevalence of subjects who tested positive to TST emerged between pre-clinical (n = 138) and clinical (n = 595) students. No statistically significant association between TST positivity and age, gender, and BCG vaccination was observed. The main independent variable associated with TST positivity was to be born in a country with a high TB incidence (i.e., ≥20 cases per 100,000 population) (adjusted OR 102.80, 95% CI 18.09-584.04, p < 0.001)., Conclusions: The prevalence of LTBI among healthcare students resulted very low. The only significant association between TST positivity and potential risk factors was to be born in high TB incidence areas. In countries with a low incidence of TB, the screening programs of healthcare students before clinical training can be useful for the early identification and treatment of the sporadic cases of LTBI.

The soluble mesothelin-related peptide (SMRP), a candidate marker for screening of subjects with asbestos exposure, is influenced by some individual and clinical factors. The aim of this study was to quantify the role of age, smoking, weight, presence of diseases and exposure to asbestos on serum SMRP levels in a large series of subjects exposed to asbestos, possible candidates for mesothelioma screening. One thousand seven hundred and four participants underwent clinical examination and were interviewed on medical anamnesis, occupation, smoking and weight. SMRP was measured by an ELISA assay. Overall, median SMRP was 0.4 (IQR 25-75: 0.3-0.7) nmol/l. It was higher in current smokers and in subjects with a cumulative asbestos exposure >50 ff/cc/years than in all the other subjects (p < 0.001 and p = 0.002, respectively). SMRP was positively correlated with age (ρ = 0.11, p < 0.001) and, inversely, with BMI (ρ = -0.15, p < 0.001). SMRP was lower in healthy subjects (n = 1,217: median 0.4 nmol/l) than in subjects with malignant tumors (n = 118: 0.5 nmol/l; p = 0.01), asbestos-related pleural lesions (plaques or thickenings, n = 152: 0.6 nmol/l; p < 0.001) and other benign diseases (n = 182: 0.5 nmol/l; p = 0.04). Multivariate analysis revealed significant predictors of increased SMRP: age >57 years, current smoking, a positive anamnesis for cancer and for asbestos-related pleural lesions, and BMI < 25. Some clinical and demographic variables are associated with serum SMRP levels. The degree of these associations is low, nevertheless they should be accounted for in the interpretation of SMPR as a candidate marker predictive of mesothelioma. The potential predictive value of serum SMRP in screening/surveillance programs must be validated in prospective studies.

Public health studies have shown that sleepiness at the wheel and other risks associated with sleep are responsible for 5% to 30% of road accidents, depending on the type of driver and/or road. In industrialized countries one-fifth of all traffic accidents can be ascribed to sleepiness behind the wheel. Sleep disorders and various common acute and chronic medical conditions together with lifestyles, extended work hours and prolonged wakefulness directly or indirectly affect the quality and quantity of one's sleep increasing the number of workers with sleep debt and staggered hours. These conditions may increase the risk of road accidents. Strategies to reduce this risk of both commercial and non-commercial drivers related to sleepiness include reliable diagnosis and treatment of sleep disorders, management of chronobiological conflicts, adequate catch-up sleep, and countermeasures against sleepiness at the wheel. Road transport safety requires the adoption of occupational health measures, including risk assessment, health education, technical-environmental prevention and health surveillance.

Sleepiness, a commonly symptom affecting up to one-fifth of the population chronically, is clearly an important cause of accidents in industry and transport inducing deterioration in performance and attention. The reason for Excessive Daytime Sleepiness (EDS) is either sleep pathology, voluntary (non-pathological) sleep reduction, or activity during the circadian low. Most of the professional accidents reported refer to the obstructive sleep apnea syndrome (OSAS). Our data confirmed higher prevalence of OSAS in truck drivers than general population and we elaborated a feasible screening tool for OSAS based on data by clinical and anthropometric variables, some items of Sleep Disorders Score and complete polysomnography. About commuting accidents (CA) in shift and non shift workers we found a strict significant relationship between shift-work condition and the presence of EDS (p < 0.0001) suggesting that CA are significantly influenced by ED in the hypothesis of disruption of the balance between circadian and homeostatic factors in shift work. In conclusion to improve safety in the workplace a standardized procedure to evaluate risks a work should be developed based on epidemiological and experimentalffindings focused on EDS.
