Determinants of LV mass in athletes: the impact of sport, constitutional traits and cardiovascular risk factors.

BACKGROUND: Whether cardiovascular (CV) risk factors might impact Left Ventricular (LV) mass in athletes is unknown. METHODS: The impact of CV risk factors (Total/LDL cholesterol, triglycerides, positive family history, smoking, body fat, blood pressure), constitutional characteristics (age, sex, body mass index) and type of sport was assessed in 1111 Olympic athletes. RESULTS: Multivariate logistic regression analysis demonstrated a significant impact: BMI ≥ 30 kg/m2 (odds ratio [OR] = 2.8. 95° Confidence Interval [CI] 0.9-13.7; < 0.001; in males); age ≥ 20-year (OR = 2.1, CI 1.4-3.3; p < 0.001) in males; (OR = 2.3; CI 1.4-3.7) in females; systolic blood pressure ≥ 130 mmHg (OR = 1.1, CI 1.01-1.16; p < 0.001) in males; (OR = 1.03; CI 1.01-1.06; p < 0.03) in females; diastolic ≥ 85 mmHg (OR = 1.1, CI 1.03-1.2; p = 0.003) in males; (OR = 1.05, CI 1.02-1.08, p < 0.001) in females. No association was found for family history, smoking, body fat, LDL, total cholesterol, triglycerides. Overall, constitutional traits explain > 60% of the LV mass. Sport explains on average 14%, but large differences existed among disciplines, i.e., endurance showed the highest impact (55%, mixed: 20%, power: 17%, skill: 8%; p < 0.001). CONCLUSION: LV mass in athletes is largely governed by constitutional traits and type of sport, and independent from CV risk factors, except for systolic and diastolic blood pressure. Overall, constitutional traits explain more than 60% of LV mass. The impact of sport is largely different in relation to the discipline, and highest in endurance, moderate mixed and power and mild in skill disciplines.

Effectiveness of clinical scores in predicting coronary artery disease in familial hypercholesterolemia: a coronary computed tomography angiography study.

PURPOSE: One of the major challenges in the management of familial hypercholesterolemia (FH) is the stratification of cardiovascular risk in asymptomatic subjects. Our purpose is to investigate the performance of clinical scoring systems, Montreal-FH-score (MFHS), SAFEHEART risk (SAFEHEART-RE) and FH risk score (FHRS) equations and Dutch Lipid Clinic Network (DLCN) diagnostic score, in predicting extent and severity of CAD at coronary computed tomography angiography (CCTA) in asymptomatic FH. MATERIAL AND METHODS: One-hundred and thirty-nine asymptomatic FH subjects were prospectively enrolled to perform CCTA. MFHS, FHRS, SAFEHEART-RE and DLCN were assessed for each patient. Atherosclerotic burden scores at CCTA (Agatston score [AS], segment stenosis score [SSS]) and CAD-RADS score were calculated and compared to clinical indices. RESULTS: Non-obstructive CAD was found in 109 patients, while 30 patients had a CAD-RADS ≥ 3. Classifying the two groups according to AS, values varied significantly for MFHS (p < 0.001), FHRS (p < 0.001) and SAFEHEART-RE (p = 0.047), while according to SSS only MFHS and FHRS showed significant differences (p < 0.001). MFHS, FHRS and SAFEHEART-RE, but not DLCN, showed significant differences between the two CAD-RADS groups (p < .001). MFHS proved to have the best discriminatory power (AUC = 0.819; 0.703-0.937, p < 0.001) at ROC analysis, followed by FHRS (AUC = 0.795; 0.715-0.875, p < .0001) and SAFEHEART-RE (AUC = .725; .61-.843, p < .001). CONCLUSIONS: Greater values of MFHS, FHRS and SAFEHEART-RE are associated to higher risk of obstructive CAD and might help to select asymptomatic patients that should be referred to CCTA for secondary prevention.

Stereotactic MR-guided adaptive radiotherapy (SMART) for primary rectal cancer: evaluation of early toxicity and pathological response.

Background: The purpose of this study is to measure the effects of stereotactic MR-guided adaptive radiotherapy (SMART) for rectal cancer patients in terms of early toxicity and pathological response. Materials and methods: For this prospective pilot study, patients diagnosed with locally advanced rectal cancer (LARC) with positive lymph node clinical staging underwent SMART on rectal lesion and mesorectum using hybrid MR-Linac (MRIdian ViewRay). Dose prescription at 80% isodose for the rectal lesion and mesorectum was 40 Gy (8 Gy/fr) and 25 Gy (5 Gy/fr), respectively, delivered on 5 days (3 fr/week). Response assessment by MRI was performed 3 weeks after SMART, then patients fit for surgery underwent total mesorectal excision. Primary endpoint was evaluation of adverse effect of radiotherapy. Secondary endpoint was pathological complete response rate. Early toxicity was graded according to the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Results: From October 2020 to January 2022, twenty patients underwent rectal SMART. No grade 3-5 toxicity was recorded. Twelve patients were eligible for total mesorectal excision (TME). Mean interval between the completion of SMART and surgery was 4 weeks. Pathological downstaging occurred in all patients; rate of pathological complete response (pCR) was 17%. pCR occurred with a prolonged time to surgery (> 7 weeks). Conclusion: To our knowledge, this is the first study to use stereotactic radiotherapy for primary rectal cancer. SMART for rectal cancer is well tolerated and effective in terms of tumor regression, especially if followed by delayed surgery.

High prevalence of Merkel cell polyomavirus is associated with dysregulation in transcript levels of TLR9 and type I IFNs in a large cohort of CF patients from the Italian (Lazio) reference center for cystic fibrosis.

Merkel cell polyomavirus (MCPyV) has been detected in respiratory specimens including those from Cystic Fibrosis (CF) patients, raising questions about its immunological and clinical relevance in the respiratory tract. MCPyV might promote an inappropriate antiviral response contributing to a chronic inflammatory response and resulting in detrimental effects in CF. Respiratory samples (n = 1138) were randomly collected from respiratory tract of CF patients (n = 539) during July 2018-October 2019. MCPyV-DNA detection was performed by real time PCR and positive samples were characterized by sequencing of the NCCR genomic region. The transcript levels of Toll-like receptor 9 (TLR9) and type I interferon (IFN-I) genes (IFNα, IFNß and IFNε) were examined by real-time RT-PCR assays. MCPyV-DNA was detected in 268 out of 1138 respiratory specimens (23.5%) without any difference in the prevalence of MCPyV-DNA according to age, gender or bacteriological status of CF individuals. Thirteen out of 137 CF patients remained positive for MCPyV-DNA over the time (a median follow-up period of 8.8 months). Detection of MCPyV-DNA in respiratory specimens was not associated with the occurrence of exacerbation events. Both MCPyV positive adolescents (11-24 years) and adults (≥25 years) had lower mRNA levels of TLR9, IFNß, IFNε and IFNα than the negative patients of the same age group, while MCPyV positive children produced increased levels of TLR9 and IFN-I genes (p < 0.05 for TLR9, IFNß, IFNε) with respect to the negative ones. There were significant differences in TLR9 levels (p < 0.01), but not in those of IFNs, between MCPyV-DNA positive and negative patients with S. aureus, P. aeruginosa or both. Overall, these results indicate that MCPyV-DNA is frequently detected in the respiratory samples of CF patients and might influence the expression levels of IFN-related genes in an age dependent manner. The concomitant detection of MCPyV together with S. aureus and/or P. aeruginosa correlated with alterations in TLR9 levels suggesting that virus-bacteria coinfections might contribute to affect antiviral immunity in CF patients.

Multidrug-resistant Acinetobacter baumannii infections in COVID-19 patients hospitalized in intensive care unit.

OBJECTIVES: Superinfections in patients hospitalized in intensive care unit (ICU) are an important and challenging complication, also in COVID-19. However, no definitive data are available about the role of multidrug-resistant Acinetobacter baumannii (MDR-AB) in COVID-19. METHODS: This was a single-center, cross-sectional study including patients with MDR-AB infections admitted to ICU with or without COVID-19, between January 2019 and January 2021. The primary objective of the study was to evaluate risk factor for MDR-AB infections in ICU patients hospitalized for COVID-19 or other etiology. The secondary endpoints were 30-days mortality in all study population and risk factors associated with development of bloodstream infection (BSI). RESULTS: During the study period 32 adults with COVID-19 were enrolled and compared with 115 patients admitted in the same ICU for other reasons. We observed a total of 114 deaths, with a survival rate of 29.3%: 18.8% in COVID-19 and 32.2% in control group. Relative risk for MDR-AB infection in COVID-19 showed that serum lactate levels mmol/l > 2, Acinetobacter baumannii colonization, BSI and steroid therapy were observed more frequently in COVID-19 patients. Cox regression analysis showed that serum lactate levels > 2 mmol/l, Acinetobacter baumannii colonization, BSI, and steroid therapy were associated with 30-days mortality. Finally, patients with COVID-19, white blood cells count > 11,000 mm3, serum lactate levels > 2 mmol/l, infections at time of ICU admission, Acinetobacter baumannii colonization, and steroid therapy were independently associated with development of BSI. CONCLUSIONS: Our data highlight the impact of BSI on outcome, the role of Acinetobacter baumannii colonization and the use of steroids on the risk to develop MDR-AB infections also during COVID-19.

The role of teicoplanin in the treatment of SARS-CoV-2 infection: A retrospective study in critically ill COVID-19 patients (Tei-COVID study).

Teicoplanin has a potential antiviral activity expressed against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and was suggested as a complementary option to treat coronavirus disease 2019 (COVID-19) patients. In this multicentric, retrospective, observational research the aim was to evaluate the impact of teicoplanin on the course of COVID-19 in critically ill patients. Fifty-five patients with severe COVID-19, hospitalized in the intensive care units (ICUs) and treated with best available therapy were retrospectively analysed. Among them 34 patients were also treated with teicoplanin (Tei-COVID group), while 21 without teicoplanin (control group). Crude in-hospital Day-30 mortality was lower in Tei-COVID group (35.2%) than in control group (42.8%), however not reaching statistical significance (p = .654). No statistically significant differences in length of stay in the ICU were observed between Tei-COVID group and control group (p = .248). On Day 14 from the ICU hospitalization, viral clearance was achieved in 64.7% patients of Tei-COVID group and 57.1% of control group, without statistical difference. Serum C-reactive protein level was significantly reduced in Tei-COVID group compared to control group, but not other biochemical parameters. Finally, Gram-positive were the causative pathogens for 25% of BSIs in Tei-COVID group and for 70.6% in controls. No side effects related to teicoplanin use were observed. Despite several limitations require further research, in this study the use of teicoplanin is not associated with a significant improvement in outcomes analysed. The antiviral activity of teicoplanin against SARS-CoV-2, previously documented, is probably more effective at early clinical stages.

Ozone as adjuvant support in the treatment of COVID-19: A preliminary report of probiozovid trial.

The evaluation of new therapeutic resources against coronavirus disease 2019 (COVID-19) represents a priority in clinical research considering the minimal options currently available. To evaluate the adjuvant use of systemic oxygen-ozone administration in the early control of disease progression in patients with COVID-19 pneumonia. PROBIOZOVID is an ongoing, interventional, randomized, prospective, and double-arm trial enrolling patient with COVID-19 pneumonia. From a total of 85 patients screened, 28 were recruited. Patients were randomly divided into ozone-autohemotherapy group (14) and control group (14). The procedure consisted in a daily double-treatment with systemic Oxygen-ozone administration for 7 days. All patients were treated with ad interim best available therapy. The primary outcome was delta in the number of patients requiring orotracheal-intubation despite treatment. Secondary outcome was the difference of mortality between the two groups. Moreover, hematological parameters were compared before and after treatment. No differences in the characteristics between groups were observed at baseline. As a preliminary report we have observed that one patient for each group needed intubation and was transferred to ITU. No deaths were observed at 7-14 days of follow up. Thirty-day mortality was 8.3% for ozone group and 10% for controls. Ozone therapy did not significantly influence inflammation markers, hematology profile, and lymphocyte subpopulations of patients treated. Ozone therapy had an impact on the need for the ventilatory support, although did not reach statistical significance. Finally, no adverse events related to the use of ozone-autohemotherapy were reported. Preliminary results, although not showing statistically significant benefits of ozone on COVID-19, did not report any toxicity.

Viral community acquired pneumonia at the emergency department: Report from the pre COVID-19 age.

The role of viruses in community acquired pneumonia (CAP) has been largely underestimated in the pre-coronavirus disease 2019 age. However, during flu seasonal early identification of viral infection in CAP is crucial to guide treatment and in-hospital management. Though recommended, the routine use of nasopharyngeal swab (NPS) to detect viral infection has been poorly scaled-up, especially in the emergency department (ED). This study sought to assess the prevalence and associated clinical outcomes of viral infections in patients with CAP during peak flu season. In this retrospective, observational study adults presenting at the ED of our hospital (Rome, Italy) with CAP from January 15th to February 22th, 2019 were enrolled. Each patient was tested on admission with Influenza rapid test and real time multiplex assay. Seventy five consecutive patients were enrolled. 30.7% (n = 23) tested positive for viral infection. Of these, 52.1% (n = 12) were H1N1/FluA. 10 patients had multiple virus co-infections. CAP with viral infection did not differ for any demographic, clinic and laboratory features by the exception of CCI and CURB-65. All intra-ED deaths and mechanical ventilations were recorded among CAP with viral infection. Testing only patients with CURB-65 score ≥2, 10 out of 12 cases of H1N1/FluA would have been detected saving up to 40% tests. Viral infection occurred in one-third of CAP during flu seasonal peak 2019. Since not otherwise distinguishable, NPS is so far the only reliable mean to identify CAP with viral infection. Testing only patients with moderate/severe CAP significantly minimize the number of tests.

Alteration of type I interferon response is associated with subclinical atherosclerosis in virologically suppressed HIV-1-infected male patients.

Given human immunodeficiency virus-1 (HIV-1)-infected patients have alterations in the type I interferon (IFN-I) pathway and are also at elevated risk of atherosclerosis, we evaluated IFN-I response and subclinical cardiovascular disease (CVD) association in HIV-1-infected patients. Transcript levels of IFN-α/ß and IFN-stimulated gene 56 (ISG56) were evaluated by RT/real-time PCR in peripheral blood mononuclear cells collected from asymptomatic HIV-1-positive male patients at high risk of developing CVD (n = 34) and healthy subjects (n = 21). Stenosis degree (≥ or <50%), calcium volume score, calcium Agatston score, and myocardial extracellular volume were examined by coronary computerized tomography scan. Carotid intima-media thickness (cIMT), Framingham risk score, atherosclerotic cardiovascular disease (ASCVD) score, and risk score developed by data collection on adverse effects of anti-HIV drugs (D:A:D) were also measured. Increased IFN-α, IFN-ß, and ISG56 levels were observed in all HIV-1-infected males compared to healthy controls (p < .001 for all genes analyzed). HIV-1-infected patients with a stenosis degree ≥50% showed a higher Framingham risk score (p = .019), which was correlated with IFN-ß and ISG56 levels. HIV-1-infected males with enhanced IFN-I levels and stenosis displayed a higher ASCVD calculated risk (p = .011) and D:A:D score (p = .004). Also, there was a trend toward higher IFN-α and ISG56 mRNA levels in HIV-1-positive patients with an increased cIMT (p > .05). Dysregulation of IFN-I response might participate in the pathogenesis of HIV-1-associated CVD.

Post-traumatic Stress Disorder Among COVID-19 Survivors at 3-Month Follow-up After Hospital Discharge.

BACKGROUND: Post-traumatic stress disorder (PTSD) is a severe but treatable mental disorder that develops after a life-threatening traumatic event. Coronavirus disease 19 (COVID-19) hospitalisation is a potentially traumatic experience, especially in severe cases. Furthermore, the unprecedented context of the severe acute respiratory syndrome coronavirus 2 pandemic, with daily media bombardment about COVID-19 mortality, may have amplified life-threatening perception also in patients with moderate infection. The aim of this study was to assess the prevalence and risk factors of PTSD at 3-month follow-up in patients hospitalised for COVID-19 infection. DESIGN: In this cohort follow-up study conducted in a large Italian academic COVID-19 hospital, 115 recruited survivors were contacted by telephone 3 months after discharge to home care. The Posttraumatic Stress Disorder Checklist for DSM-5 was administered. Multivariate logistic regression models were used to analyse risk factors for the development of PTSD. KEY RESULTS: A total of 10.4% of the sample received a PCL-5-based diagnosis of PTSD. Other 8.6% of the sample received a diagnosis of subthreshold PTSD, which leads to significant levels of distress and impairment. Multivariate regression analysis indicated that previous psychiatric diagnosis (odds ratio (OR) = 6.3, 95% confidence interval (CI): 3.7-78.6, p < 0.001) and obesity (OR = 3.51, 95% CI: 1.4-857.9, p = 0.03) were risk factors for developing PTSD. Chronic pulmonary diseases approached significance as a risk factor (OR = 6.03, 95% CI: 1.0-37.1, p = 0.053). Male sex was a protective factor (OR=0.04, 95% CI: 0.0-0.041, p = 0.007). CONCLUSIONS: PTSD and subthreshold PTSD rates in patients hospitalised for COVID-19 are worrying. Female sex and pre-existing mental disorders are established risk factors for PTSD, while the prospective association with obesity needs further investigation. Clinicians treating COVID-19 should consider screening for PTSD at follow-up assessments in patients discharged from the hospital.

Antibiotic Prophylaxis for Percutaneous Endoscopic Gastrostomy in Children: A Randomised Controlled Trial.

OBJECTIVES: Paediatric studies on the role of antibiotic prophylaxis in the prevention of postoperative infections in children undergoing percutaneous endoscopic gastrostomy (PEG) are lacking. The aim of this study was to assess if a single dose of co-amoxiclav before PEG can decrease the rate of peristomal wound and systemic infection in children. METHODS: In this prospective, randomised, double-blind, multicentre trial, children undergoing PEG were randomized to antibiotic prophylaxis with co-amoxiclav versus placebo and the rate of local and systemic infections were assessed. RESULTS: Of the 106 patients considered for inclusion, 49 patients were randomized. In the per-protocol analysis, the occurrence of wound infection was 5% (1/20) in the antibiotic group and 21% (4/19) in the placebo group (P = 0.13, 16% difference in proportions, odds ratio [OR] 0.19, 95% confidence interval [CI] 0.02-1.9). The occurrence of systemic infection was 9% (2/22) in the antibiotic group and 27.2% (6/25) in the placebo group [P = 0.17, 18% difference in proportions, OR 0.32, 95% CI 0.06%-1.80%]. Similar results were obtained in intention-to-treat analysis. Interestingly, the overall infection rate was significantly higher in the placebo group as compared with the antibiotic group (40% vs 13.6%; P = 0.04) and the duration of hospital stay was significantly longer in the placebo group as compared with the antibiotic group (4.4 ±â€Š1.6 vs 3.5 ±â€Š1.05; P = 0.02). The number-needed-to-treat (NTT) to prevent 1 peristomal infection on average are 6.7 patients. CONCLUSIONS: A preoperative dose of co-amoxiclav reduces the overall infection rate and the duration of hospital stay. Our data suggest that antibiotic prophylaxis should be recommended in every children undergoing PEG placement.

qSOFA as a new community-acquired pneumonia severity score in the emergency setting.

BACKGROUND: Quick Sequential Organ Failure Assessment (qSOFA) score is a bedside prognostic tool for patients with suspected infection outside the intensive care unit (ICU), which is particularly useful when laboratory analyses are not readily available. However, its performance in potentially septic patients with community-acquired pneumonia (CAP) needs to be examined further, especially in relation to early outcomes affecting acute management. OBJECTIVE: First, to compare the performance of qSOFA and CURB-65 in the prediction of mortality in the emergency department in patients presenting with CAP. Second, to study patients who required critical care support (CCS) and ICU admission. METHODS: Between January and December 2017, a 1-year retrospective observational study was carried out of adult (≥18 years old) patients presenting to the emergency department (ED) of our hospital (Rome, Italy) with CAP. The accuracy of qSOFA, qSOFA-65 and CURB-65 was compared in predicting mortality in the ED, CCS requirement and ICU admission. The concordance among scores ≥2 was then assessed for 30-day estimated mortality prediction. RESULTS: 505 patients with CAP were enrolled. Median age was 71.0 years and mortality rate in the ED was 4.7%. The areas under the curve (AUCs) of qSOFA-65, CURB-65 and qSOFA in predicting mortality rate in the ED were 0.949 (95% CI 0.873 to 0.976), 0.923 (0.867 to 0.980) and 0.909 (0.847 to 0.971), respectively. The likelihood ratio of a patient having a qSOFA score ≥2 points was higher than for qSOFA-65 or CURB-65 (11 vs 7 vs 6.7). The AUCs of qSOFA, qSOFA-65 and CURB-65 in predicting CCS requirement were 0.862 (95% CI 0.802 to 0.923), 0.824 (0.758 to 0.890) and 0.821 (0.754 to 0.888), respectively. The AUCs of qSOFA-65, qSOFA and CURB-65 in predicting ICU admission were 0.593 (95% CI 0.511 to 0.676), 0.585 (0.503 to 0.667) and 0.570 (0.488 to 0.653), respectively. The concordance between qSOFA-65 and CURB-65 in 30-day estimated mortality prediction was 93%. CONCLUSION: qSOFA is a valuable score for predicting mortality in the ED and for the prompt identification of patients with CAP requiring CCS. qSOFA-65 may further improve the performance of this useful score, showing also good concordance with CURB-65 in 30-day estimated mortality prediction.

Cognitive impairment and CSF proteome modification after oral bacteriotherapy in HIV patients.

OBJECTIVE: To investigate whether a probiotic supplementation to cART patients modifies the cerebrospinal fluid (CSF) proteome and improves neurocognitive impairment. METHODS: 26 CSF samples from 13 HIV-positive patients [six patients living with HIV (PLHIV) and seven patients with a history of AIDS (PHAIDS)] were analyzed. All patients underwent to neurocognitive evaluation and blood sampling at baseline and after 6 months of oral bacteriotherapy. Immune phenotyping and activation markers (CD38 and HLA-DR) were evaluated on peripheral blood mononuclear cells (PBMC). Plasma levels of IL-6, sCD14, and MIP-1ß were detected, by enzyme-linked immunosorbent assay (ELISA). Functional proteomic analysis of CSF sample was conducted by two-dimensional electrophoresis; a multivariate analysis was performed by principal component analysis (PCA) and data were enriched by STRING software. RESULTS: Oral bacteriotherapy leads to an improvement on several cognitive test and neurocognitive performance in both groups of HIV-positive subjects. A reduction in the percentage of CD4+CD38+HLA-DR+ T cells was also observed at peripheral level after the probiotic intake (p = 0.008). In addition, the probiotic supplementation to cART significantly modifies protein species composition and abundance at the CSF level, especially those related to inflammation (ß2-microglobulin p = 0.03; haptoglobin p = 0.06; albumin p = 0.003; hemoglobin p = 0.003; immunoglobulin heavy chains constant region p = 0.02, transthyretin p = 0.02) in PLHIV and PHAIDS. CONCLUSIONS: Our results suggest that oral bacteriotherapy as a supplement to cART could exert a role in the amelioration of inflammation state at peripheral and CNS level.

Physical Activity and HIV: Effects on Fitness Status, Metabolism, Inflammation and Immune-Activation.

Several studies evidenced that a sedentary lifestyle is related with higher levels of systemic inflammation and highlighted that physical activity can trigger anti-inflammatory effects. To evaluate the impact of self-prescribed physical activity on fitness status, metabolism, inflammation and immune-activation in people living with HIV, an interim analysis of the results of the clinical trial PRIMO (NCT03392805) was performed. Patients enrolled were divided in 2 groups on the basis of self-prescribed physical activity: a physically active group (self-prescribed physical activity) and a sedentary group. Physical fitness was evaluated by sport medicine specialists and related to nutritional status, anthropometric variables, adipokines levels (adiponectin, leptin, resistin), peripheral immune-activation (CD38, HLA-DR on CD4 and CD8), and plasma inflammatory markers (IL-6 and TNF-α). The physically active group had a better profile in anthropometric measures and aerobic fitness but did not show lower levels of immune-activation compared to sedentary group. Also serum IL-6, TNF-α, and adipokines levels showed no statistical differences. On the basis of these data, a regular self-organized physical activity seems useful to improve cardio-respiratory fitness, but unable to control HIV-related immune-activation.

Carotid Artery Aneurysm in HIV: A Review of Case Reports in Literature.

BACKGROUND: HIV infection may affect the cardiovascular system through different physiopathological patterns. Rarely reported in HIV negative patients, aneurysms involving the carotid artery have been described for the first time in seropositive patients in 1989. AIMS: In our study, we have focused on aneurysm pathology affecting carotid arteries in HIV patients, analyzing clinical and surgical presentation, management, and outcome, through a review of cases published in the literature. METHODS: The MEDLINE (www.ncbi.nlm.nih.gov/pubmed) database was reviewed for "carotid artery aneurysm AND HIV OR AIDS OR immunodeficiency." RESULTS: Nineteen articles including a total of 46 cases were included in our report. The mean age of patients was 30.6 ± 14.2 years; 30 patients (65.2%) were male. Aneurysms were localized in the intracranial carotid (41.3%) or extracranial artery (58%). Presenting features included symptoms due to compression of neck structures; positivity for neurological symptoms occurred in 36.9%. Patients were managed surgically in 58.7% of cases; surgical morbidity and mortality were of 22.2% and 7.4% respectively, higher for endovascular procedures. The overall mortality in treated and untreated cases was 26.1%. CONCLUSIONS: Aneurysms may occur in both the extracranial and intracranial carotid artery in patients with HIV at younger age than in non-HIV patients and are linked to a high morbidity and mortality. Seropositivity must be ruled out whenever this rare vascular condition may occur in the absence of a more likely aetiology and must also be suspected in HIV patients presenting with compressive symptoms of the neck, neurological impairment or stroke.

Clinical outcomes in adult athletes with hypertrophic cardiomyopathy: a 7-year follow-up study.

OBJECTIVE: Current guidelines recommend precautionary disqualification from competitive sports in patients with hypertrophic cardiomyopathy (HCM). We assessed the incidence of cardiovascular events in a cohort of patients with HCM engaged in long-term exercise programmes and competitive sport. METHODS: We reviewed data on 88 consecutive athletes diagnosed with HCM, from 1997 to 2017; 92% male, 98% Caucasian, median age 31 (IQR: 19-44) years. All participated in regular exercise programmes and competitive sport at study entry.We performed follow-up evaluation after 7±5 (1-21) years. 61 (69%) of the athletes had substantially reduced or stopped exercise and sport (ie, HCM-detrained), and 27 had continued with regular training and sport competitions (HCM-trained). At baseline evaluation, both groups were similar for age, gender balance, symptoms, ECG abnormalities, extent of left ventricular hypertrophy, arrhythmias and risk profile for sudden cardiac death/arrest. RESULTS: During the follow-up period, two participants suffered sudden cardiac arrest or death (0.3% per year) both outside of sport participation. In addition, 19 (22%) reported symptoms (syncope in 3, palpitations in 10, chest pain in 4 and dyspnoea in 2). The Kaplan-Meier analyses of freedom from combined sudden cardiac arrest/death and symptoms (log-rank test p=0.264) showed no differences between HCM-trained and detrained patients. CONCLUSION: In this adult cohort of low-risk HCM athletes, voluntary decision to pursue in participation in competitive sport events was not associated with increased risk for major cardiac events or clinical worsening compared with decision to reduce or withdraw from exercise programmes and sport. Similar results may not be seen in younger or racially diverse athlete populations, or in patients with more severe HCM phenotypes.

Many Different Patterns under a Common Flag: Aortic Pathology in HIV-A Review of Case Reports in Literature.

BACKGROUND: Availability of highly active antiretroviral therapy (HAART) for HIV has prolonged life expectancy of patients but has also increased the incidence of non-AIDS comorbid conditions. Among these, there are cardiovascular diseases, and aortic involvement has been described in patients with HIV in the form of aortitis, aneurysms, or dissections. Our study aims to describe aortic pathology occurring in patients with HIV, focusing on clinical and surgical presentation, management, and outcome, through a review of cases published in literature. METHODS: MEDLINE (www.ncbi.nlm.nih.gov/pubmed) database was reviewed for "aortitis" OR "aortic aneurysm" OR "aortic dissection" AND HIV. Research was restricted to English language. Only case reports were included. Data on patients' age, sex, traditional risk factors, timing from HIV diagnosis, pharmacological details, coinfection (syphilis, hepatitis C virus [HCV], and hepatitis B virus [HBV]), anatomical localization of lesion, presence of inflammatory involvement, rapid growing or rupture, and surgical treatment and outcomes were collected and summarized in tables. RESULTS: Forty articles (51 cases) were included in the study. The mean age of patients was 48.8 ± 8.3 years. Male sex was preponderant (43 cases, 84.3%). Among traditional risk factors, hypertension and smoking were the most frequently reported ones (14 and 13 cases, respectively), followed by vasculopathy involving other arterial districts, dyslipidemia, diabetes, and drug addiction. In 3 cases, HIV was diagnosed in the same time as aortic pathology, whereas in most cases, aortic event occurred after five years from HIV diagnosis. In 30.5% of cases for which data on pharmacologic management were available, no treatment or poor adherence was reported. Coinfection occurred in some cases (syphilis in 6, HCV in 5, and HBV in 3). As for anatomical involvement, isolated thoracic lesions were more frequent (24, 47.1%), followed by abdominal and thoracoabdominal lesions. The etiology ranged from bacterial mycotic aneurysms to tertiary syphilis, postsurgical complications, or atherosclerosis. In 3 cases, HIV vasculitis was directly suggested, and in another 2, no other potential etiology had been diagnosed through cultural tests. Open surgical treatment was carried out in 30 cases (58.8%), and in addition, 10 endovascular (19.6%) and 2 hybrid procedures were described. Inflammatory features occurred in 7 cases, and a rapid evolution of lesions in 6. In 9 cases (17.6%), rupture occurred. Mortality was reported in 8 cases (15.7%). CONCLUSIONS: Aortic pathology may occur in patients with HIV. The entanglement of different patterns of pathological involvement of the aortic wall, secondary to immune dysregulation, infectious process, or atherosclerotic damage that may co-occur in one single case, results in a very challenging management of the condition. Because of the increased life expectancy of patients and immigration from regions with both high HIV and coinfection prevalence, the incidence of aortic pathology could increase in the upcoming years, suggesting the urgent need for further studies to optimize management in these very complex cases.

Impact of the 2017 measles outbreak on the emergency care system of a large tertiary-care teaching hospital in Italy: a retrospective analysis.

BACKGROUND: A large outbreak of measles has spread across Italy over the year 2017. Its impact on emergency department (ED) of a tertiary-care teaching hospital and the related critical issues in public health were evaluated. METHODS: Medical records of adults discharged from January to December 2017 with diagnosis of 'measles' or 'measles suspicion' were collected and analyzed. RESULTS: From a total of 58 579 admissions, 218 medical records matched enrollment criteria. Measles infection was confirmed in 55.3% of patients, excluded in 26.2%, and judged as possible or probable in 18.3% of cases. Considered that the vaccination status was unknown in 89.2% of patients, the mean time spent in temporary isolation rooms (TIRs) waiting serological results was 1.7 ± 0.8 days. Measles-free patients spent a mean of 1.9 ± 0.9 days in TIRs, meaning a cumulative unnecessary time of isolation of 106.4 days. Despite most of patients were pauci-simptomatic and with a low burden of comorbidities, only 28.6% of them reported a previous out-of-hospital medical contact. Moreover an assessment of moderately critical conditions was assigned to 89.6% of cases, representing an over-valuation of the severity of the cases. Antibiotic therapy had been prescribed in 69.0% of cases and 57.7% of patients were hospitalized. We found no differences in terms of median time spent in TIRs, rate of hospitalization and antibiotic prescription between measles cases and measles-free patients. CONCLUSION: A preventable high-infective disease outbreak can lead to a misapply of ED facilities in terms of unjustified admissions, time spent in TIRs, antibiotic prescription and in hospitalization rate.

The role of cardiac magnetic resonance in sports cardiology: results from a large cohort of athletes.

BACKGROUND: Cardiac magnetic resonance (CMR) provides information on morpho-functional abnormalities and myocardial tissue characterisation. Appropriate indications for CMR in athletes are uncertain. OBJECTIVE: To analyse the CMR performed at our Institute to evaluate variables associated with pathologic findings in a large cohort of athletes presenting with different clinical conditions. METHODS: All the CMR performed at our Institute in athletes aged > 14 years were recruited. CMR indications were investigated. CMR was categorised as "positive" or "negative" based on the presence of morphological and/or functional abnormalities and/or the presence of late gadolinium enhancement (excluding the right ventricular insertion point), fat infiltration, or oedema. Variables associated with "positive" CMR were explored. RESULTS: A total of 503 CMR were included in the analysis. "Negative" and "positive" CMR were 61% and 39%, respectively. Uncommon ventricular arrhythmias (VAs) were the most frequent indications for CMR, but the proportion of positive results was low (37%), and only polymorphic ventricular patterns were associated with positive CMR (p = 0.006). T-wave inversion at 12-lead ECG, particularly on lateral and inferolateral leads, was associated with positive CMR in 34% of athletes (p = 0.05). Echocardiography abnormalities resulted in a large proportion (58%) of positive CMR, mostly cardiomyopathies. CONCLUSION: CMR is more efficient in identifying a pathologic cardiac substrate in athletes in case of VAs (i.e., polymorphic beats), abnormal ECG repolarisation (negative T-waves in inferolateral leads), and borderline echocardiographic findings (LV hypertrophy, mildly depressed LV function). On the other hand, CMR is associated with a large proportion of negative results. Therefore, a careful clinical selection is needed to indicate CMR in athletes appropriately.
