RESUMO
BACKGROUND: Venous thromboembolism is a frequent complication of COVID-19 infection. Less than 50% of pulmonary embolism (PE) is associated with the evidence of deep venous thrombosis (DVT) of the lower extremities. DVT may also occur in the venous system of the upper limbs especially if provoking conditions are present such as continuous positive airway pressure (CPAP). The aim of this study was to evaluate the incidence of UEDVT in patients affected by moderate-severe COVID-19 infection and to identify potential associated risk factors for its occurrence. METHODS: We performed a retrospective analysis of all patients affected by moderate-severe COVID-19 infection admitted to our unit. In accordance with the local protocol, all patients had undergone a systematic screening for the diagnosis of UEDVT, by vein compression ultrasonography (CUS). All the patients were receiving pharmacological thromboprophylaxis according to international guidelines recommendations. Univariate and multivariate analyses were used to identify risk factors associated with UEDVT. RESULTS: 257 patients were included in the study, 28 patients were affected by UEDVT with an incidence of 10.9% (95% CI, 7.1-14.7). At univariate analysis UEDVT appeared to be significantly associated (p< 0.05) with pneumonia, ARDS, PaO2/FiO2, D-dimer value higher than the age adjusted cut off value and need for CPAP ventilation. Multivariate analysis showed a significant association between UEDVT and the need for CPAP ventilation (OR 5.95; 95% IC 1.33-26.58). Increased mortality was found in patients affected by UEDVT compared to those who were not (OR 3.71; 95% CI, 1.41-9.78). CONCLUSIONS: UEDVT can occur in COVID-19 patients despite adequate prophylaxis especially in patients undergoing helmet CPAP ventilation. Further studies are needed to identify the correct strategy to prevent DVT in these patients.

OBJECTIVE: To address the lack of information about clinical sequelae of coronavirus disease 2019 (COVID-19). PATIENTS AND METHODS: Previously hospitalized COVID-19 patients who were attending the outpatient clinic for post-COVID-19 patients (ASST Ovest Milanese, Magenta, Italy) were included in this retrospective study. They underwent blood draw for complete blood count, C-reactive protein, ferritin, D-dimer, and arterial blood gas analysis and chest high-resolution computed tomography (HRCT) scan. The primary endpoint was the assessment of blood gas exchanges after 3 months. Other endpoints included the assessment of symptoms and chest HRCT scan abnormalities and changes in inflammatory biomarkers after 3 months from hospital admission. RESULTS: Eighty-eight patients (n = 65 men; 73.9%) were included. Admission arterial blood gas analysis showed hypoxia and hypocapnia and an arterial partial pressure of oxygen/fractional inspired oxygen ratio of 271.4 (interquartile range [IQR]: 238-304.7) mm Hg that greatly improved after 3 months (426.19 [IQR: 395.2-461.9] mm Hg, P<.001). Forty percent of patients were still hypocapnic after 3 months. Inflammatory biomarkers dramatically improved after 3 months from hospitalization. Fever, resting dyspnea, and cough were common at hospital admission and improved after 3 months, when dyspnea on exertion and arthralgias arose. On chest HRCT scan, more than half of individuals still presented with interstitial involvement after 3 months. Positive correlations between the interstitial pattern at 3 months and dyspnea on admission were found. C-reactive protein at admission was positively associated with the presence of interstitial involvement at follow-up. The persistence of cough was associated with presence of bronchiectasis and consolidation on follow-up chest HRCT scan. CONCLUSION: Whereas inflammatory biomarker levels normalized after 3 months, signs of lung damage persisted for a longer period. These findings support the need for implementing post-COVID-19 outpatient clinics to closely follow-up COVID-19 patients after hospitalization.
RESUMO
ABSTRACT: Although myocarditis can be a severe cardiac complication of COVID-19 patients, few data are available in the literature about the incidence and clinical significance in patients affected by SARS-CoV-2. This study aims to describe the prevalence and the clinical features of suspected myocarditis in 3 cohorts of patients hospitalized for COVID-19. We retrospectively evaluated all the consecutive patients admitted for COVID-19 without exclusion criteria. Suspect myocarditis was defined according to current guidelines. Age, sex, in-hospital death, length of stay, comorbidities, serum cardiac markers, interleukin-6, electrocardiogram, echocardiogram, and therapy were recorded. Between March 4 to May 20, 2020, 1169 patients with COVID-19 were admitted in 3 Italian Medicine wards. 12 patients (1%) had suspected acute myocarditis; 5 (41.7%) were men, mean age was 76 (SD 11.34; median 78.5âyears); length of stay was 38âdays on average (SD 8, median value 37.5); 3 (25%) patients died. 8 (66.7%) had a history of cardiac disease; 7 (58.33%) patients had other comorbidities like diabetes, chronic obstructive pulmonary disease, or renal insufficiency. Myocarditis patients had no difference in sex prevalence, rate of death, comorbidities, elevations in serum cardiac markers as compared with patients without myocardial involvement. Otherwise, there was a significantly higher need for oxygen-support and a higher prevalence of cardiac disease in the myocarditis group. Patients with suspected myocarditis were older, had a higher frequency of previous cardiac disease, and significantly more prolonged hospitalization and a lower value of interleukin-6 than other COVID-19 patients. Further studies, specifically designed on this issue, are warranted.

BACKGROUND: Chest radiography is universally accepted as the method of choice to confirm correct positioning of a nasogastric tube (NGT). Considering also that radiation exposure could increase with multiple insertions in a single patient, bedside abdominal ultrasound (BAU) may be a potentially useful alternative to chest radiography in the management of NGTs. RESEARCH QUESTION: What is the accuracy of BAU in confirming the correct positioning of an NGT? STUDY DESIGN AND METHODS: After a specific course consisting of 10 h of training, the authors studied, in a prospective multicenter cohort, the validity of BAU to confirm correct NGT placement. All patients were also evaluated by auscultation (whoosh test) and by chest radiography. Every involved operator was blind to each other. Interobserver agreement and accuracy analyses were calculated. RESULTS: This study evaluated 606 consecutive inpatients with an indication for NGT insertion. Eighty patients were excluded for protocol violation or incomplete examinations and 526 were analyzed. BAU was positive, negative, and inconclusive in 415 (78.9%), 71 (13.5%), and 40 (7.6%), respectively. The agreement between BAU and chest radiography was excellent. Excluding inconclusive results, BAU had a sensitivity of 99.8% (99.3%-100%), a specificity of 91.0% (88.5%-93.6%), a positive predictive value of 98.3% (97.2%-99.5%), and a negative predictive value of 98.6% (97.6%-99.7%). The accuracy of BAU slightly changed according to the different assignments of the uncertain cases and was improved by the exclusion of patients with an altered level of consciousness. INTERPRETATION: These results suggest that BAU has a good positive predictive value and may confirm the correct placement of NGTs when compared with chest radiography. However, considering its suboptimal specificity, caution is necessary before implementing this technique in clinical practice.

BACKGROUND: Most studies on SARS-CoV-2 infection show that people who have recovered from COVID-19 have antibodies to the virus. No study has evaluated whether the presence of antibodies to SARS-CoV-2 confers immunity to the infection relapse but however, to date, no human reinfections with SARS-CoV-2 have been confirmed. MATERIAL AND METHODS: In our prospective, multicenter, cohort study we investigated within three months all patients, with confirmed COVID-19, discharged from two Hospitals (Legnano and Magenta Hospitals), in an area of Italy severely affected by the infection. Telephone follow-up at 1 and 2 months and clinical contact within 3 months was initiated; demographic, clinical, radiologic and laboratory data were recorded in electronic medical records and updated. RESULTS: Of 1081 patients involved, 804 (74.3%) were discharged alive. For all these patients we obtained follow-up data. At 1 and 2 months none has died and none has had any signs of recurrence of infectious at both telephone interview and clinical visit. CONCLUSION: Our clinical observation have confirmed two basic points: the reinfection is very unlikely and any antibody immunity protects against recurrence, at least in the short term.

INTRODUCTION: Pulmonary embolism (PE) prevalence in acute exacerbations of COPD is highly variable. METHODS: To investigate the prevalence and risk factors of PE in patients hospitalized in Departments of Internal Medicine because of AECOPD and suspected PE we conducted a retrospective multicenter study in patients with an AECOPD undergoing chest angio-computed tomography (angio-CT) because of clinical suspect of PE. RESULTS: 1043 patients (mean age 75.8 years ± 9.7 years, 34.5 % women) were included; 132 patients had PE (mean prevalence 12.66%, 95% confidence interval 10.73, 14.77%).) confirmed by angio-CT and 54 patients died during hospitalization (5.18 %). At multivariate analysis, age, female gender, clinical signs and symptoms suggestive of deep vein thrombosis, hypertension, PaCO2 ≤ 40 mmHg, and normal chest-x-ray were significantly associated with a higher PE prevalence. Prevalence of PE in patients with 0, 1, 2, 3 or ≥4 risk factors progressively increase from 1.76 to 30.43%. Mean length of hospitalization (LOH) (15.7 vs 14.2 days, p 0.07) and in-hospital mortality (6.1% vs 5.1%, P=0.62) were slightly but not significantly higher in in patients with PE (6.1% vs 5.1%, P=0.62). CONCLUSIONS: PE prevalence is not negligible in this setting. A number of risk factors may help clinicians in identification of patients at increased risk of PE.

BACKGROUND: Patients with suspected deep vein thrombosis (DVT) of the lower limb represent a diagnostic dilemma for general practitioners. Compression ultrasonography (US) is universally recognized as the best test of choice. We assessed the diagnostic accuracy of compression US performed by general practitioners given short training in the management of symptomatic proximal DVT. METHODS: From May 2014 to May 2016, we evaluated in a multicenter, prospective cohort study all consecutive outpatients with suspected DVT; bilateral proximal lower limb compression US was performed by general practitioners and by physicians expert in vascular US, each group blinded to the other's findings. In all examinations with a negative or nondiagnostic result, compression US was repeated by the same operator after 5 to 7 days. Inter-observer agreement and accuracy were calculated. RESULTS: We enrolled a total of 1,107 patients. The expert physicians diagnosed DVT in 200 patients, corresponding to an overall prevalence of 18.1% (95% CI, 15.8%-20.3%). The agreement between the trained general practitioners and the experts was excellent (Cohen κ = 0.86; 95% CI, 0.84-0.88). Compression US performed by general practitioners had a sensitivity of 90.0% (95% CI, 88.2%-91.8%) and a specificity of 97.1% (95% CI, 96.2%-98.1%) with a diagnostic accuracy for DVT of 95.8% (95% CI, 94.7%-97.0%). CONCLUSIONS: Our results suggest that, even in hands of physicians not expert in vascular US, compression US can be a reliable tool in the diagnosis of DVT. We found that the sensitivity achieved by general practitioners appeared suboptimal, however, so future studies should evaluate the implementation of proper training strategies to maximize skill.

: Atrial fibrillation is the most common arrhythmia in over-midlife patients. In addition to systolic heart failure, cerebral thromboembolism represents the most dramatic complication of this rhythm disorder, contributing to morbidity and mortality. Traditionally, anticoagulation has been considered the main strategy in preventing stroke and systemic embolism in atrial fibrillation patients and vitamin K-dependent antagonists have been widely used in clinical practice. Recently, the development of direct oral anticoagulants has certainly improved the management of this disease, providing, for the first time, the opportunity to go beyond vitamin K-dependent antagonists limits. In the RE-LY trial, dabigatran 150âmg twice daily was superior to warfarin in the prevention of stroke or systemic embolism and dabigatran 110âmg twice daily was noninferior. Both doses greatly reduced hemorrhagic stroke, and dabigatran 110âmg twice daily significantly reduced major bleeding compared with warfarin. Based on these results, dabigatran, a direct thrombin inhibitor, was the first direct oral anticoagulant to receive the regulatory approval for nonvalvular atrial fibrillation patients. To date, a specific reversal agent has just been approved as an antidote for this molecule. This review provides a summary of randomized trials, postmarket registries and specific clinical-settings summary on dabigatran in nonvalvular atrial fibrillation.

In clinical practice lung ultrasound (LUS) is becoming an easy and reliable noninvasive tool for the evaluation of dyspnea. The aim of this study was to assess the accuracy of nurse-performed LUS, in particular, in the diagnosis of acute cardiogenic pulmonary congestion. We prospectively evaluated all the consecutive patients admitted for dyspnea in our Medicine Department between April and July 2014. At admission, serum brain natriuretic peptide (BNP) levels and LUS was performed by trained nurses blinded to clinical and laboratory data. The accuracy of nurse-performed LUS alone and combined with BNP for the diagnosis of acute cardiogenic dyspnea was calculated. Two hundred twenty-six patients (41.6% men, mean age 78.7â±â12.7 years) were included in the study. Nurse-performed LUS alone had a sensitivity of 95.3% (95% CI: 92.6-98.1%), a specificity of 88.2% (95% CI: 84.0-92.4%), a positive predictive value of 87.9% (95% CI: 83.7-92.2%) and a negative predictive value of 95.5% (95% CI: 92.7-98.2%). The combination of nurse-performed LUS with BNP level (cut-off 400âpg/mL) resulted in a higher sensitivity (98.9%, 95% CI: 97.4-100%), negative predictive value (98.8%, 95% CI: 97.2-100%), and corresponding negative likelihood ratio (0.01, 95% CI: 0.0, 0.07). Nurse-performed LUS had a good accuracy in the diagnosis of acute cardiogenic dyspnea. Use of this technique in combination with BNP seems to be useful in ruling out cardiogenic dyspnea. Other studies are warranted to confirm our preliminary findings and to establish the role of this tool in other settings.

Given the rare nature of Madelung's disease many clinicians will not have seen a patient with it and will not be able to recognise them: subsequently a diagnosis is unlikely to be made.
RESUMO
Elderly patients admitted to the hospital are at increased risk for both in-hospital and post-discharge mortality. Risk assessment models (RAMs) for in-hospital mortality are based mainly on physiological variables and a few laboratory data, whereas RAMs for late mortality usually include other domains such as disability and comorbidities. We aim to evaluate if a previous validated model for 1-year mortality (the Walter Score) would also work well in predicting in-hospital mortality. We retrospectively revised the medical records of patients admitted on our ward, from April to December, 2013. Data regarding gender, activities of daily living (ADLs), comorbidities, and routine laboratory tests were used to calculate a Modified Walter Score (MoWS). The main outcome measure was all cause, in-hospital mortality. The analysis involved 1,004 patients. Of these, 888 were discharged alive, and 116 (11.5 %) died during the hospitalization. The mean MoWS was 4.9 (±3.6) in the whole sample. Stratification into risk classes parallels with in-hospital mortality (Chi square for trend p < 0.001). When dichotomized, MoWS has a sensitivity of 97.4 % (95 % CI 92.1-99.3), and a specificity of 48.2 % (95 % CI 44.9-51.5) with a good prognostic accuracy (area under the ROC = 0.81; 95 % CI 0.78, 0.84). Subgroup analysis according to different age groups gives similar results. A simple RAM based on multiple domains, previously validated for predicting mortality of older adults within 1 year from the index hospitalization, can be useful at the moment of admission to Internal Medicine wards to accurately identify patients at low risk of in-hospital mortality.

OBJECTIVES: Identification and quantification higher risk incidence of aortic rupture or dissection (AARD) could be of clinical interest and improve preventive strategies. BACKGROUND: Several studies and subsequent meta-analyses have shown chronobiologic variations in the timing of occurrence of myocardial infarction, stroke, and pulmonary embolism. Conversely, such evidences are currently lacking for AARD despite a number of studies available dealing with periodicity. METHODS: MEDLINE, EMBASE, and Google Scholar databases were searched up to July 2013. Temporal variation in the incidence of AARD was analyzed including all studies analyzing seasonal, monthly, weekly, and circadian aggregations. Two authors independently reviewed and extracted data. RESULTS: Forty-two studies for a total of more than 80 000 patients were included. Our results showed a significantly increased incidence of AARD in Winter (Chi-square 854.92, p < 0.001), with a relative risk (RR) of 1.171 (99% CI 1.169, 1.172), in December (Chi-square 361.03, p < 0.001), RR of 1.142 (99% CI 1.141, 1.143), on Monday (Chi-square 428.09, p < 0.001), RR of 1.214 (99% CI 1.211, 1.216), and in the hours between 6 am and 12 pm (Chi-square 212.02, p < 0.001), RR of 1.585 (99% CI 1.562, 1.609). Subgroup and sensitivity analyses confirmed the results of principal analyses. CONCLUSIONS: Our data strongly support the presence of evident rhythmic patterns in the incidence of acute aortic events, characterized by significantly higher risk in Winter, in December, on Monday and between 6 am and 12 pm. Future studies are needed to better clarify the underlying mechanisms and clinical implications.
