Multidrug-resistant (MDR) organisms are emerging as some of the main healthcare problems worldwide. During the COVID-19 pandemic, several Infection Prevention and Control (IPC) measures have been adopted to reduce nosocomial microorganism transmission. We performed a case–control study to identify if the incidence of MDR bacterial infections while using pandemic-related preventive measures is lower than in previous years. From 2017 to 2020, we monitored hospital discharges over a four-month period (P #) (1 March to 30 June) in St. Andrea Hospital, Rome. In total, we reported 1617 discharges. Pearson’s chi-squared test was used to identify significant differences. A value of p ≤ 0.05 was considered statistically significant. A significant reduction in the incidence of total MDR bacterial infections was observed during the pandemic compared to in prepandemic years (p < 0.05). We also found a significantly higher incidence of MDR bacterial infections in COVID-19 departments compared with other medical departments (29% and 19%, respectively), with extended-spectrum β-lactamase Klebsiella pneumoniae as the pathogens presenting the highest increase. This study demonstrates that maintaining a high level of preventive measures could help tackle an important health problem such as that of the spread of MDR bacteria.

Background: Takotsubo syndrome is usually triggered by a stressful event. The type of trigger seems to influence the outcome and should therefore be considered separately. Methods and Results: Patients included in the GEIST (German‐Italian‐Spanish Takotsubo) registry were categorized according to physical trigger (PT), emotional trigger (ET), and no trigger (NT) of Takotsubo syndrome. Clinical characteristics as well as outcome predictors were analyzed. Overall, 2482 patients were included. ET was detected in 910 patients (36.7%), PT in 885 patients (34.4%), and NT was observed in 717 patients (28.9%). Compared with patients with PT or NT, patients with ET were younger, less frequently men, and had a lower prevalence of comorbidities. Adverse in‐hospital events (NT: 18.8% versus PT: 27.1% versus ET: 12.1%, P <0.001) and long‐term mortality rates (NT: 14.4% versus PT: 21.6% versus ET: 8.5%, P <0.001) were significantly lower in patients with ET. Increasing age ( P <0.001), male sex ( P =0.007), diabetes ( P <0.001), malignancy ( P =0.002), and a neurological disorder ( P <0.001) were associated with a higher risk of long‐term mortality, while chest pain ( P =0.035) and treatment with angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker ( P =0.027) were confirmed as independent predictors for a lower risk of long‐term mortality. Conclusions: Patients with ET have better clinical conditions and a lower mortality rate. Increasing age, male sex, malignancy, a neurological disorder, chest pain, angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker, and diabetes were confirmed as predictors of long‐term mortality.

Background: Neurological disorders as a risk factor for Takotsubo syndrome (TTS) are not well characterized. The aim of the study was to evaluate TTS‐associated neurological phenotypes and outcome. Methods and Results: Patients with TTS enrolled in the international multicenter GEIST (German Italian Spanish Takotsubo) registry were analyzed. Prevalence, clinical characteristics, and short‐ and long‐term outcomes of patients with TTS were recorded. A subgroup analysis of the 5 most represented neurological disorders was performed. In total, 400 (17%) of 2301 patients had neurological disorders. The most represented neurological conditions were previous cerebrovascular events (39%), followed by neurodegenerative disorders (30.7%), migraine (10%), epilepsy (9.5%), and brain tumors (5%). During hospitalization, patients with neurological disorders had longer in‐hospital stay (8 [interquartile range, 5–12] versus 6 [interquartile range, 5–9] days; P <0.01) and more often experienced in‐hospital complications (27% versus 16%; P =0.01) mainly driven by cardiogenic shock and in‐hospital death (12% versus 7.6% and 6.5% versus 2.8%, respectively; both P <0.01). Survival analysis showed a higher mortality rate in neurological patients both at 60 days and long‐term (8.8% versus 3.4% and 23.5% versus 10.1%, respectively; both P <0.01). Neurological disorder was an independent predictor of both the 60‐day and long‐term mortality rate (odds ratio, 1.78 [95% CI, 1.07–2.97]; P =0.02; hazard ratio, 1.72 [95% CI, 1.33–2.22]; both P <0.001). Patients with neurodegenerative disorders had the worst prognosis among the neurological disease subgroups, whereas patients with TTS with migraine had a favorable prognosis (long‐term mortality rates, 29.2% and 9.7%, respectively). Conclusions: Neurological disorders identify a high‐risk TTS subgroup for enhanced short‐ and long‐term mortality rate. Careful recognition of neurological disorders and phenotype is therefore needed.

Aims: Exercise oscillatory ventilation (EOV) is a pivotal cardiopulmonary exercise test parameter for the prognostic evaluation of patients with chronic heart failure (HF). It has been described in patients with HF with reduced ejection fraction (50%, HFpEF), but no data are available for patients with HF with mid-range ejection fraction (40–49%, HFmrEF). The aim of the study was to evaluate the prognostic role of EOV in HFmrEF patients. Methods and results: We analysed 1239 patients with HFmrEF and 4482 patients with HFrEF, enrolled in the MECKI score database, with a 2-year follow-up. The study endpoint was the composite of cardiovascular death, urgent heart transplant, and ventricular assist device implantation. We identified EOV in 968 cases (16% and 17% of cases in HFmrEF and HFrEF, respectively). HFrEF EOV+ patients were significantly older, and their parameters suggested a more severe HF than HFrEF EOV− patients. A similar behaviour was found in HFmrEF EOV+ vs. EOV− patients. Kaplan–Meier analysis, irrespective of ejection fraction, showed that EOV is associated with a worse survival, and that patients with HFrEF and HFmrEF EOV+ had a significantly worse outcome than the EOV− of the same ejection fraction groups. EOV-associated survival differences in HFmrEF patients started after 18 months of follow-up. Conclusion: Exercise oscillatory ventilation has a similar prevalence and ominous prognostic value in both HFmrEF and HFrEF patients, indicating a group of patients in need of a more intensive follow-up and a more aggressive therapy. In HFmrEF, the survival curves between EOV+ and EOV− patients diverged only after 18 months.

Myocardial oedema is largely represented in takotsubo syndrome (TTS) and may contribute to alter the myocardium morphology and function. The aim of the study is to describe relationships between oedema, mechanical, and electrical abnormalities in TTS the study included n = 32 hospitalized TTS patients and n = 23 controls. Cardiac magnetic resonance (CMR) with tissue mapping and feature tracking was performed with concomitant 12-lead electrocardiogram (ECG) recording. Mean age of TTS was 72 ± 12 years old, 94% women. Compared with controls, patients had higher left ventricular (LV) mass, worse systolic function, higher septal native T1 (1116 ± 73 msec vs. 970 ± 23 msec, P < 0.001), T2 (56 ± 5 msec vs. 46 ± 2 msec, P < 0.001), and extracellular volume (ECV) fraction (32 ± 5% vs. 24 ± 1%, P < 0.001). TTS patients had higher apicobasal gradient of T2 values (12 ± 6 msec vs. 2 ± 6 msec, P < 0.001); basal LV wall displayed higher native T1, T2, and ECV (all P < 0.002) but similar circumferential strain against controls (−23 ± 3% vs. −24 ± 4%, P = 0.351). In the TTS cohort, septal T2 values showed significant correlations with native T1 (r = 0.609, P < 0.001), ECV (r = 0.689, P < 0.001), left ventricular ejection fraction (r = −0.459, P = 0.008) and aVR voltage (r = −0.478, P = 0.009). Negative T-wave voltage and QTc length correlated with apicobasal T2 mapping gradient (r = 0.499, P = 0.007 and r = 0.372, P = 0.047, respectively) but not with other tissue mapping measurements. CMR T1 and T2 mapping demonstrated increased myocardial water content conditioning interstitial expansion in acute TTS, detected even outside areas of abnormal wall motion. Oedema burden and distribution associated with mechanical and electrocardiographic changes, making it a potential prognostic marker and therapeutic target in TTS.
