The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a single-stranded, positive-sense RNA virus. The SARS-CoV-2 virus is evolving continuously, and many variants have been detected over the last few years. SARS-CoV-2, as an RNA virus, is more prone to mutating. The continuous evolution of the SARS-CoV-2 virus is due to genetic mutation and recombination during the genomic replication process. Recombination is a naturally occurring phenomenon in which two distinct viral lineages simultaneously infect the same cellular entity in an individual. The evolution rate depends on the rate of mutation. The rate of mutation is variable among the RNA viruses, with the SARS-CoV-2 virus exhibiting a lower rate of mutation than other RNA viruses. The novel 3'-to-5' exoribonuclease proofreading machinery is responsible for a lower rate of mutation. Infections due to SARS-CoV-2, influenza, and respiratory syncytial virus have been reported from around the world during the same period of fall and winter, resulting in a "tripledemic". The JN.1 variant, which evolved from the predecessor, the Omicron variant BA.2.86, is currently the most dominant globally. The impact of the JN.1 variant on transmissibility, disease severity, immune evasion, and diagnostic and therapeutic escape will be discussed.

Non-A non-B aortic dissection is considered a rare nosological entity, included in the Stanford classification, representing a small percentage of the total aortic dissections that occur annually. Regarding this form, the literature reports a more complicated disease course compared to other types of dissection. We describe the case of a 76-year-old patient who accessed the triage section of an emergency department for a polytrauma picture and, after surgical treatment of a leg fracture, received a diagnosis of non-A non-B aortic dissection, "localized" to the arch and incidentally detected. The angio-computed tomography (CT) showed that the only intimal tear was located in the central portion of the aortic arch, with no exit tear. No signs of malperfusion or clinical symptoms related to the aortic finding were evident. The Aortic Team decided on a conservative approach, whereby the patient was started on medical therapy to control blood pressure in a monitored bed of a semi-intensive care unit. The persistent asymptomatic state, a condition of hemodynamic stability, and an unchanged angio-CT picture enabled discharge on day 7 and the assignment to a close follow-up.

Chronic obstructive pulmonary disease (COPD) is characterized by permanent airflow obstruction due to abnormalities of the airways and alveoli. This study investigated the potential role of Aspergillus species in acute exacerbations of COPD (AE-COPD) and evaluated the diagnostic utility of serum Aspergillus galactomannan antigen. This cross-sectional study, carried out at the Jawaharlal Institute of Postgraduate Medical Education and Research from January 2021 to June 2022, involved COPD patients aged ≥40 years. Serum galactomannan and serum Aspergillus-specific antibodies were analyzed, along with the collection of demographic details, symptoms, and comorbidities. Statistical analyses, including univariate analysis and receiver operating characteristic (ROC) curve analysis, were performed. Among the 61 recruited COPD patients, 24.5% showed serum galactomannan positivity. Significant associations were found between galactomannan positivity, hemoptysis, and previous tuberculosis. ROC analysis revealed modest diagnostic accuracy (area under the ROC=0.6027) with a sensitivity of 44.4% and a specificity of 83.7% at a cut-off of 0.5. Univariate analysis did not show any potential links between diabetes, hypertension, previous exacerbations, and severe Global Initiative for Chronic Obstructive Lung Disease stages with a risk of exacerbation. Serum galactomannan antigen showed limited sensitivity, and its routine testing may not be justified for predicting exacerbation risk. Further studies are warranted to validate these findings and explore other diagnostic methods using bronchoalveolar lavage galactomannan antigen in AE-COPD.

Preserved ratio impaired spirometry (PRISM), defined by reduced forced expiratory volume in 1 second (FEV1) without meeting criteria for airway obstruction, is often encountered in clinical practice. The management of this heterogeneous condition in individuals with chronic respiratory symptoms is challenging, especially under limited diagnostic resources. Since 2020, all consecutive patients referred for spirometry at our institution have been invited to participate in our registry. Other than spirometry, no other physiological lung function testing is available in this public health service. Therefore, we reviewed our databank with the aim of assessing: i) the proportion of symptomatic patients aged 18 years or older referred for spirometry presenting with PRISM; ii) the rate of inhaled medication used in this group, suggesting a referral diagnosis of obstructive airway disease (OAD); and iii) the relationship between symptoms and results on spirometry in PRISM compared to a group with obstruction matched by FEV1. To this end, the chronic obstructive airway disease assessment test (CAT) and the asthma control test (ACT) were jointly responded to by 1032 participants, irrespective of the clinical suspicion. We found that 22% had PRISM, of whom 200 were paired with obstruction by FEV1 (68±10% of predicted). The CAT and ACT results were well-correlated in both groups (r=-0.727 and -0.698, respectively; p<0.001) and used to measure symptoms. Participants in the final sample (n=400) were aged 62±13 years; 70% were ever smokers; and 55% reported household exposure to biomass smoke (at least 5 years). The CAT responses were in the range of moderate symptoms (17±9) and ACT borderline for uncontrolled symptoms (19±5). The main differences were higher body mass index (33±7 vs. 29±7 kg/m2; p<0.001) and proportion of females (72 vs. 49%; p<0.001) in PRISM compared to obstruction. This group had lower exposure to tobacco (65 vs. 76% of ever-smokers) but greater exposure to biomass smoke (61 vs. 49%) (p<0.05 for all). The rate of inhaled medication use was as high in PRISM as in obstruction (80%). Notwithstanding matched FEV1, we found less prominent signs of airway disease in PRISM: marginally reduced FEV1/forced vital capacity (FVC) ratio (94±8% of predicted); higher expiratory flow between 25% and 75% of vital capacity, despite presumed lower lung volumes (lower FVC); and lower rate of bronchial hyperresponsiveness. In an identical multivariate model, FEV1 predicted symptoms of obstruction only. In conclusion, these data raise suspicion of a substantial rate of misclassification of individuals with PRISM as having OAD in healthcare facilities with constraints on diagnostic resources.

Over the years, halotherapy (HT) has shown promise in the treatment of respiratory and dermatological diseases. However, its widespread acceptance remains limited due to the absence of official guidelines and awareness among doctors and patients. Among the patented systems of administration of HT, Aerosal® is the only one consisting of 3 certified elements, all classified as Medical Devices Class 2A: a dry saline dispenser called Aerosalmed®, a 30 g salt dose named AeroNaCL®, and a confined environment in marine multilayered construction with walls coated in salt called Aerosal®. We conducted an online survey of subjects undergoing Aerosal® HT across 80 Italian centers. Participants provided demographic data, reasons for choosing HT, and perceptions of its effectiveness. Following 10 treatment sessions, they rated improvements in various aspects, such as skin condition, sleep quality, relaxation, and respiratory benefits. Most participants learned about HT through word of mouth rather than medical advice, suggesting a discrepancy between patient satisfaction and medical endorsement. Over 92% reported resolution of their health issues post-treatment, with significant improvements in sleep quality and relaxation, particularly in adults. The therapy showed promise in various conditions, including respiratory and skin disorders, possibly attributed to stress reduction and intrinsic therapeutic effects. Despite skepticism, HT administered through the Aerosal® system has shown therapeutic potential. The psycho-physical benefits observed in patients advocate for greater consideration of this therapy by clinicians, emphasizing its safety, tolerability, and absence of notable side effects. In this context, standardized systems like Aerosal® are crucial for ensuring treatment safety and efficacy.

Coronary heart disease (CHD) remains a leading cause of mortality among cancer patients, primarily due to shared risk factors and the impacts of chemotherapeutic drugs, immune checkpoint inhibitors, and radiotherapy. Determining the optimal treatment strategy remains a challenging issue for patients with concurrent CHD and malignant neoplasms. In high-risk patients, managing CHD frequently takes precedence over addressing the oncologic disease. Myocardial revascularization, coupled with optimal medical therapy for CHD, can significantly enhance patient survival by reducing the risks of myocardial infarction and sudden cardiac death. However, selecting a surgical treatment strategy requires careful consideration of the indications, the complexity of coronary lesions, the risk of bleeding and thrombosis, and the overall prognosis of the malignancy. This clinical case demonstrates the importance of risk-benefit assessment, multidisciplinary discussion of cure strategy, and application of novel technologies to provide the most personalized and effective treatment.

In patients at high cardiovascular risk, a low-density lipoprotein cholesterol (LDL-C) reduction of ≥50% from baseline and an LDL-C goal of <70 mg/dL (or <55 mg/dL in very high-risk patients) are recommended. Multiple registry and retrospective studies have shown that patients with high atherosclerotic cardiovascular risk often do not reach the targets defined by the European Society of Cardiology guidelines as a result of suboptimal management of LDL-C. Here, we report the data on lipid-lowering therapy and lipid targets from the Survey on Risk FactOrs and CardiovascuLar secondary prEvention and drug strategieS (SOFOCLES), an observational, prospective study designed to collect data on patients with ischemic heart disease treated at cardiac outpatient clinics across the Italian national territory. We included patients with known coronary heart disease (CHD) who underwent follow-up visits at various outpatient cardiology clinics. A total of 2532 patients were included (mean age: 67±17 years, 80% male). Among patients with available laboratory data (n=1712), 995 (58%) had LDL-C<70 mg/dL, 717 (42%) had LDL-C≥70 mg/dL, and 470 (27%) had LDL-C<55 mg/dL. Patients who more frequently achieved the recommended LDL-C levels were male, had diabetes, had a higher educational level, and performed intense physical activity. Statins were used in 2339 (92%) patients, high-intensity statins (e.g., rosuvastatin 20/40 mg or atorvastatin 40/80 mg) in 1547 patients (61% of the whole population and 66% of patients on statins), and ezetimibe in 891 patients (35%). Patients receiving high-intensity statins tended to be younger, not to have diabetes, and to have been included in a cardiac rehabilitation program. In a real-world sample of Italian patients with CHD, adherence to lipid-lowering therapy fell markedly short of optimal levels. Many patients did not achieve the LDL-C target of 70 mg/dL, and even fewer reached the LDL-C target of 55 mg/dL. Notably, patients with a lower educational level had a greater likelihood of being undertreated. Strategies aimed at improving preventive interventions for CHD and overcoming social disparities should be evaluated and optimized.

Infective endocarditis (IE) is a life-threatening condition with high morbidity and mortality rates, making early diagnosis and intervention crucial. This report details the case of a male with a history of mechanical prosthetic aortic valve replacement, presenting with pyrexia and diagnosed with aortic bioprosthetic endocarditis leading to a massive aortic pseudoaneurysm. This shows that 3D transesophageal echocardiography is much more useful than regular 2D imaging for finding problems with IE, which makes surgical planning and intervention more precise.

Worldwide, approximately half of the patients diagnosed with lung cancer (LC) will develop, simultaneously or asynchronously, brain metastases (BMs). The existence of BMs negatively affects the quality of life and constitutes a poor prognostic factor, linked with high mortality. Locoregional therapy with surgery or radiation is, until now, the treatment of choice, especially for symptomatic patients; however, both options are linked to a high complication rate. The question arising here is whether, in asymptomatic patients, the benefit outweighs the risk and whether an alternative method can be used to treat this special category of patients. Over the last decade, immune checkpoint inhibitors (ICIs) have represented a major breakthrough in the field of oncology, and several molecules have been approved as a treatment option for LC. This review tried to analyze the tumor microenvironment of both the primary lung tumor and the BMs in order to evaluate the intracranial activity of ICIs, outline the main challenges of including these agents in the treatment of LC with BMs, highlight the available information from the main clinical trials, and mark the potential positive effect of choosing a combination therapy. In conclusion, it appears that immunotherapy has a positive effect, inhibiting the progression of BMs, but more data should be published specifically for this category of patients.
