Background: Prompt reperfusion is critical for patients with ST-segment elevation myocardial infarction (STEMI) to improve outcomes. Yet, variability in regional healthcare delivery may influence treatment times and patient outcomes. We thus aimed at evaluating differences in management and outcomes of STEMI patients across Northern, Central, and Southern Italy, focusing on time-dependent reperfusion and in-hospital logistics.

Methods: A prospective observational study conducted from September 1^st to 25^th, 2023, including 554 STEMI patients treated at high-volume hub centers operating 24/7. Data were collected through structured surveys completed by catheterization laboratory directors across different Italian regions. Primary outcomes included door-to-balloon (DTB) time, time from symptom onset to balloon inflation, and regional disparities in pre- and post-PCI management. Secondary outcomes included in-hospital mortality, discharge destinations, and medication regimens.

Results: The median DTB time was consistent across regions (30 minutes; IQR: 20-50 minutes). Significant regional disparities were however noted in time from symptom onset to balloon inflation, with Southern and Island regions experiencing longer median times (180 minutes) compared to Central (170 minutes) and Northern (154 minutes) regions (P<0.01). We also found a significant reduction in DTB time associated with ECG teletransmission from ambulances (mean reduction of 25 minutes, P=0.03). In-hospital mortality rates were similar across regions (P=0.83).

Conclusions: This comprehensive nationwide analysis highlights significant regional disparities in the management and treatment timelines of STEMI patients in Italy. Despite these differences, in-hospital care was consistently timely across regions, suggesting that pre-hospital logistics critically influence overall treatment times. Enhanced pre-hospital ECG teletransmission could further optimize reperfusion times, potentially improving patient outcomes.

Introduction: Despite advancement of therapeutic approaches to recurrent pericarditis, it poses notable challenges to its' management. As per the current guidelines, colchicine is the first line therapy, although, non-conventional treatments like interleukin-1 (IL-1) antagonists (rilonacept, anakinra, goflikicept) are progressively utilized for refractory cases.

Evidence acquisition: A comprehensive electronic search identified relevant literature across multiple databases, focusing on recurrence rates and adverse effects associated with each treatment regimen.

Evidence synthesis: Eleven studies (6 on colchicine, 5 on IL-1 antagonists) involving 1053 patients were included. Colchicine significantly reduced recurrence risk by 63% (OR 0.37, 95% CI 0.27-0.52). IL-1 antagonists demonstrated superior efficacy: anakinra reduced recurrence by 98% (OR 0.02, 95% CI 0.01-0.07), rilonacept by 98% (OR 0.02, 95% CI 0.01-0.07), and goflikicept by 99% (OR 0.01, 95% CI 0.00-0.05). Adverse effects were comparable between colchicine and IL-1 antagonists except for rilonacept, which showed a higher risk (OR 5.70, 95% CI 2.13-15.27).

Conclusions: IL-1 antagonists significantly reduce recurrent pericarditis episodes compared to colchicine, with anakinra, rilonacept, and goflikicept demonstrating high efficacy and acceptable safety profiles. These findings support their consideration as alternative therapies in colchicine-refractory cases of recurrent pericarditis. Further studies are warranted to refine treatment guidelines and optimize patient outcomes.

Background: The finding of mutations that activate epidermal growth factor receptor (EGFR) in people with lung adenocarcinoma resulted in the creation of a new class of biological treatments called tyrosine kinase inhibitors (TKI). These medications have changed how patients with EGFR mutations are clinically managed, nearly doubling their survival rate compared to standard chemotherapy. Though 1st and 2nd generation EGFR TKIs are initially highly effective, typically within 9-14 months all tumors with the mutation progress due to secondary resistance mutations involving alternative molecular pathways. In most cases (up to 60%), this is due to the T790M mutation emerging in the EGFR gene.

Methods: The study included 85 patients with NSCLC with progression of the disease after treatment with TKI 1st and 2nd generation. The T790M mutation was determined by digital polymerase chain reaction (PCR) on the QIAcuity One 5plex digital PCR system and traditional real-time PCR. Real-time PCR analysis of the presence of the T790M mutation was performed using the Therascreen EGFR Plasma RGQ PCR Kit (Qiagen). Using a digital PCR system in QIAcuity One (Qiagen) nanoplanets, the T790M mutation was analysed by digital PCR. The age of the patients ranged from 37 to 85 years.

Results: Of 85 patients with NSCLC with disease progression after TKI treatment, T790M mutations were detected during digital PCR in 30 of 85 patients, which is 35.2% of the sample, and with traditional real-time PCR, positive mutations came out only in 3 out of 85 patients.

Conclusions: Thus, completed study can assert that digital PCR is able to replace traditional real-time PCR as a more preferable method of high-performance quantitative determination of target nucleic acids and has a relatively high sensitivity without compromising high specificity. Results of this research also show that a liquid biopsy using digital PCR provides an opportunity to avoid repeated tissue biopsy in patients who cannot provide a tumor tissue sample suitable for molecular analysis.

Rheumatoid arthritis (RA) is an autoimmune inflammatory condition that primarily affects the joints and periarticular soft tissue. The development of joint swelling is traditionally regarded as the starting point of the disease. Emerging evidence indicates that RA patients often experience a preclinical stage characterized by immunological and inflammatory changes before developing the disease. The review discusses ongoing efforts to predict the transition from this preclinical phase to clinical RA and describes studies aimed at preventing the onset of RA in individuals at risk. Over the past two decades, there have been significant advancements in RA management and outcomes. An increasing number of patients can now achieve disease remission, and in some cases, this remission persists without ongoing treatment, which is effectively a cure. As new therapies and evolving scientific evidence emerge, recommendations for RA management are continuously evolving. Despite these improvements in the management of RA, many patients still do not respond to multiple conventional or more advanced therapies, including biologic and targeted synthetic disease modifying anti-rheumatic drugs, or experience disease flares when treatments are tapered or discontinued. This situation underscores the need for reliable biomarkers to guide therapy more effectively, improve personalized treatment approaches and monitoring strategies (i.e. precision medicine). In conclusion, this review provides a comprehensive overview of RA, covering new research on the 'pre-clinical' phase of the disease, as well as its epidemiology, pathogenesis, clinical manifestations, diagnosis, imaging, and management strategies. It highlights key clinical aspects of RA and addresses ongoing challenges in disease management, particularly in the areas of prevention and treatment.

Introduction: Recently, the FFR-Guidance for Complete Nonculprit Revascularization (FULL REVASC) trial in ST elevation myocardial infarction (STEMI) patients with multiple vessel disease (MVD) did not show differences in the composite endpoint of death from any cause, myocardial infarction, or unplanned revascularization than culprit-lesion-only percutaneous coronary intervention (PCI) at 4.8 years, although complete revascularization is a recommendation IA in current guidelines. We want to determine through an updated meta-analysis whether complete revascularization is associated with decreased mortality and hard clinical endpoints compared to culprit lesion only PCI.

Evidence acquisition: We searched MEDLINE, Embase, ISI Web of Science, and Cochrane Central Register of Controlled Trials) from January 1990 to April 2024 using the terms "percutaneous coronary intervention" combined with "non culprit lesions" or "culprit lesion" or "complete revascularization" or "incomplete revascularization." Additionally, a "snowball search" was conducted. Only randomized clinical trials (RCT) reporting mortality, re-infarction or new revascularization after at least 12 months and using predominantly drug eluting stents were included. The summary effect of different revascularization strategies on cardiovascular endpoints was estimated and measures of effect size were expressed as odds ratios (ORs).

Evidence synthesis: Eight RCT involving 9515 patients were included, with a follow-up range between 12 months and 4.8 years. Main findings show that culprit lesion revascularization was associated with an increased risk of MI (OR: 1.38; 95% CI: 1.05 to 1.81, I2 42%) and ischemia-guided revascularization (OR: 2.81; 95% CI: 1.86 to 4.26, I2 80%) compared to complete revascularization, without differences in overall mortality (OR: 1.15; 95% CI: 0.98 to 1.36, I2 2%).

Conclusions: In patients with STEMI and MVD without cardiogenic shock, our metanalysis showed that complete revascularization with PCI significantly reduced the risk of non-fatal myocardial reinfarction and ischemic-driven revascularization compared to culprit vessel-only revascularization, without differences in overall mortality.

Tricuspid regurgitation (TR), an underrecognized disease, overlooked by clinicians for many years due to its assumed benign nature. Recent epidemiological studies suggest significant TR may be seen in up to 6% of elderly patients. An increase in prevalence is expected due to the higher incidence of various clinical predictors of TR progression. Increasing severity of TR is associated with worse outcomes with a novel morphologic classification providing a more refined prediction of outcomes. Advances in cardiac imaging, particularly echocardiography, are integral to the diagnosis of disease severity which not only includes quantitation of TR, but also an assessment of the right atrium, right ventricle and pulmonary arterial circulation. Once identified and quantified, TR management requires a multi-disciplinary heart team management including structural imagers, heart failure specialists, electrophysiologist, cardiac surgeons and interventionalists. Data to support medical therapies are lacking although guidelines support the management of congestive signs and symptoms, as well as comorbidities such as left heart failure and rhythm management. The risks of surgical interventions are slowly improving, however, transcatheter therapies are now available to treat patients with high surgical risk. This manuscript will provide a state-of-art review of this fast-moving field, including current scientific evidences, but also upcoming perspectives with multiple ongoing clinical studies.

Background: Takotsubo syndrome (TTS) is an acute reversible heart dysfunction affecting mostly post-menopausal women, frequently precipitated by a significant stressful event, presenting as an acute coronary syndrome (ACS) in the absence of obstructive coronary artery disease. The pathogenesis is not fully understood, but a close relationship between individual's mind, brain, neuroendocrine system and the heart may be involved in a mind-heart axis. The purpose of this study was to compare the prevalence of psychopathological findings in TTS patients as compared to healthy subjects, patients affected by psychiatric diseases and patients affected by ACS.

Methods: This observational study enrolled 40 female subjects divided into 4 subgroups: TTS patients, healthy subjects, psychiatric patients and ACS patients, matched for age. Psychosocial factors and psychopathological dimensions have been evaluated. Patients who signed informed consent were interviewed by the administration of a complex psychometric battery, including Mini International Neuropsychiatric Interview, Hamilton Rating Scale for Depression, State Trait Anxiety Inventory, Form Y.

Results: Comparing the groups, the TTS group showed a statistically significant difference vs. ACS group concerning psychological violence subscale (P=0.049) of the Childhood Trauma Questionnaire, while significant statistical difference emerged in TTS group vs. healthy subjects control group, regarding cyclothymia subscale (P=0.008). Statistically significant differences were documented in TTS group vs. psychiatric cohort in cyclothymia subscale (P=0.012). Moreover, comparison between TTS and ACS group, revealed a statistically significant difference in the sub-scale of self-confidence and management of negative emotions (P=0.0028). One of the most significant features was the evidence of statistically significant differences in TTS vs. ACS group, concerning total and average value of anxiety (P=0.014 and P=0.031 respectively) and in the comparison of TTS group vs. healthy subjects (P=0.005 for the total anxiety value and P=0.021 for the average value). Finally, both depression and mania were statistically significant raised in the TTS group compared to the healthy subjects' group (P=0.00 and P=0.013, respectively).

Conclusions: Psychosocial and psychopathological dimensions of TTS patients have been explored and analyzed in a cohort of TTS patients vs. ACS, healthy subjects and psychiatric patients, showing statistically significant differences among the various groups. Psychopathological symptoms were more frequent in TTS patients, suggesting an evident involvement of mind-heart axis in this disease. Future studies are needed to investigate the cause-effect relationship between psychopathological features and the occurrence of TTS.

Since the publication of the recent North American and European guidelines on management of Clostridioides difficile infection (CDI), new evidence describing the epidemiology, testing and treatment of CDI has emerged. Despite all advances in infection control and antibiotic stewardship, the incidence and burden of CDI in the hospitals and the community remains at a stable high. Coupled with the incidence of primary CDI, there is a stable high incidence of recurrent CDI. Testing for primary and recurrent CDI remains a clinical challenge owing to high sensitivity of the PCR (leading to false positives) and somewhat limited sensitivity of EIA for toxin. The pathophysiology of recurrent CDI involves an ongoing disruption of the microbiota owing to the infection and the treatment of CDI employed. Broad spectrum antibiotics such as vancomycin leads to further disruption of microbiota compared to fidaxomicin which has a lower disruption of the microbiota and leads to fewer recurrences. Owing to these data fidaxomicin is considered as the first line antibiotic for recurrent CDI. Intravenous bezlotoxumab is a monoclonal antibody that reduces the risk of recurrence in high-risk patients but does not restore the microbiota. Experimental fecal microbiota transplantation (FMT) has been available for more than a decade. Owing to the success of FMT, two new non-invasive donor dependent Food and Drug Administration (FDA) approved therapies have been available since late 2022. This review summarizes all these conundrums regarding CDI and provides clinical pearls to use in day-to-day practice.
