Despite performance of primary PCI, patients with AMI due to LMCA occlusion were associated with >50% in-hospital mortality. Hemodynamic deficit upon arrival was the major determinant of their poor hospital outcomes. The hospital survivors, however, were associated with favorable long-term outcomes.
During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, patients with STelevation myocardial infarction (STEMI) should be treated as possibly infected individuals. Therefore, more time is considered necessary to conduct primary percutaneous coronary intervention (PCI). In this study, we sought to evaluate the impact of the SARS-CoV-2 pandemic on primary PCI for STEMI. Between March 2019 and March 2021, 259 patients with STEMI underwent primary PCI. Patients were divided into 2 groups: the pre-pandemic group (March 2019-February 2020) and the pandemic group (March 2020-February 2021). The patient demographics, reperfusion time including onset-to-door time, door-to-balloon time (DTBT), computed tomography (CT), peak creatinine phosphokinase (CPK), and 30-day mortality rate were investigated. The mean age of the patients was 70.4 ± 12.9 years, and 71.6% were male. There were 117 patients before the pandemic and 142 during the pandemic. The median DTBT was 29 (21.25-41.25) minutes before the pandemic and 48 minutes (31-73 minutes) during the pandemic (P < 0.001). The median door-to-catheter-laboratory time was 13.5 (10-18.75) minutes before the pandemic and 29.5 (18-47.25) minutes during the pandemic (P < 0.001). CT evaluation was performed before PCI in 39 (33.3%) patients and 63 (44.4%) patients (P = 0.08); their peak CPK levels were 1480 (358-2737.5) IU and 1363 (621-2722.75) IU (P = 0.56), and the 30-day mortality rates were 4.3% and 2.1% (P = 0.48), respectively. The SARS-CoV-2 pandemic changed the diagnostic procedure in the emergency department and affected the DTBT in patients with STEMI. Nonetheless, no adverse effects on the 30-day mortality rate were observed.
Aim
Clostridioides difficile infection worsens the outcome of older hospitalized patients; thus, its diagnosis is necessary for the nosocomial infection control. The standard diagnostic test's limited sensitivity for Clostridioides difficile infection, an enzyme immunoassay for Clostridioides difficile toxins, is of clinical concern. Glutamate dehydrogenase detection is usually tested combined with Clostridioides difficile toxins. However, the clinical significance of a positive glutamate dehydrogenase result is unclear. We evaluated the association between positive glutamate dehydrogenase results, in‐hospital mortality and hospital stay length among older patients with suspected Clostridioides difficile infection.
Methods
In this retrospective cohort study, we examined the data of patients who received antibiotics (except for Clostridioides difficile infection treatment) after admission and tested for Clostridioides difficile infection using an enzyme immunoassay for Clostridioides difficile toxins and glutamate dehydrogenase in a secondary care hospital located in a rural region with high aging rate, between 2015 and 2018.
Results
In total, 188 patients were included (83.5% of them aged >75 years). Glutamate dehydrogenase positivity was independently associated with in‐hospital mortality (adjusted odds ratio 2.19, 95% confidence interval 1.14–4.21) and hospital stay length (regression coefficient 16.0, 95% confidence interval 5.15–26.9). Clostridioides difficile toxin positivity was independently associated with hospital stay duration (regression coefficient 14.5, 95% confidence interval 0.04–29.1), unlike in‐hospital mortality.
Conclusions
Glutamate dehydrogenase was closely related to in‐hospital mortality and prolonged hospitalization compared with Clostridioides difficile toxin. Clinicians should not neglect glutamate dehydrogenase‐positive patients, even when they are Clostridioides difficile toxin‐negative, and consider them as having poor prognostic potential.

Background
The distal transradial approach (dTRA) for coronary catheterisation is a newly introduced alternative to the conventional transradial approach. This technique is expected to decrease the incidence of haemorrhagic complications and improve patient comfort. However, limited data are available regarding the application of this technique in patients with acute myocardial infarction (AMI). This study investigated the feasibility and safety of the dTRA for primary percutaneous coronary intervention (PCI) in patients with AMI.
Methods
This study included patients with AMI who underwent primary PCI via the distal radial artery across 3 Japanese hospitals between January 2018 and January 2019. Patients' background, procedural characteristics, and clinical outcomes including the incidence of haemorrhagic complications were analysed.
Results
This study enrolled 95 consecutive patients with AMI, including 68 patients (71.6%) with ST-segment elevation myocardial infarction (STEMI), in whom distal radial artery puncture was attempted for primary PCI. The patients included 70 men (73.7%), and the mean age was 72.2±12.4 years. Among these patients, cannulation was successfully performed in 89 patients (93.7%). A 5-, 6-, or 7-French sheath (conventional or slender) was used in this study. Cannulation was performed using a forearm radial artery approach in patients in whom dTRA failed.
PCI was successfully performed in all patients. The meantime to achieve haemostasis was 6.3±5.3 hours, and no major bleeding complications occurred. Based on The Early Discharge After Transradial Stenting of Coronary Arteries trial haematoma scale, grade I, II, and III subcutaneous haemorrhages were observed in 16 (16.8%), 4 (4.2%), and 1 patient (1.1%), respectively. No patient developed a haematoma > grade IV.
In patients with STEMI, the mean door-to-balloon time was 39.4±31.9 min, and the mean puncture-to-balloon time was 19.7±14.2 min.
Conclusions
The distal radial approach is feasible and safefor primary PCI in selected patients with AMI.The application of the dTRA may serve as a less invasive strategy for the treatment of patients with AMI.
