Raise-up technique for the creation of left atrial roof lesion: A useful technique with cryoballoon for persistent atrial fibrillation.

INTRODUCTION: Recent studies have reported the efficacy of the cryoballoon (CB)-guided left atrial roof block line (LARB) creation in patients with persistent atrial fibrillation (AF). However, it can be technically challenging to attach the balloon to the left atrial (LA) roof due to its anatomical variations. We designed a new procedure called the "Raise-up Technique," which may facilitate the firm adhesion of the CB to the LA roof during freezing. This study aimed to evaluate the efficacy of the Raise-up technique in LARB creation. METHODS AND RESULTS: In total, 100 consecutive patients with persistent AF who underwent CB-LARB creation were enrolled. Fifty-seven patients underwent LARB creation using the Raise-up technique (Raise-up group), and the remaining 43 did not use it (control group). The Raise-up technique was performed as follows: An Achieve catheter was inserted as deeply as possible into the upper branch of the right superior pulmonary vein to anchor the CB. The balloon was placed below the targeted site on the LA roof and frozen. When the temperature of the CB reached approximately -10°C and the CB was easier to attach to the LA tissue, the CB was raised and pressed against the LA roof immediately by sheath advancement. Then the balloon could be in firm contact with the target site on the roof. If necessary, additional sheath advancement after sufficient freezing (-20°C to -30°C) was allowed the CB to have more firm and broad contact with the target site. LARB creation without touch-up ablation was achieved in 54 of 57 patients (94.7%) in the Raise-up group and 33 of 43 patients (76.7%) in the control group (p < .05). The lesion size of the LARB in the Raise-up group was significantly larger than that in the control group (15.2 cm2 vs. 12.8 cm2, p < .05). Moreover, the width of the LARB lesion in the Raise-up group was wider than that in the control group (32.0 mm vs. 26.6 mm, p < .05). CONCLUSION: The Raise-up technique enabled the creation of seamless and thick LARB lesions with a single stroke. In addition, the CB-LARB lesions created using the Raise-up technique tended to be large, resulting in extensive debulking of the LA posterior wall arrhythmia substrates. In CB ablation for persistent AF, the Raise-up technique can be considered one of the key strategies for LARB creation.

Vaccination status, incidence of adverse events, and awareness of COVID-19 vaccine among outpatients undergoing chemotherapy.

BACKGROUND: Cancer has been identified as a risk factor for severe illness and mortality in coronavirus disease (COVID-19), underscoring the importance of recommending COVID-19 vaccinations to patients with cancer. However, few reports have focused on the vaccination status and the incidence of adverse events among patients with cancer. In this study, we aimed to evaluate the vaccination status, incidence of adverse events, concerns, and anxiety related to COVID-19 vaccination among patients with cancer. In addition, we explored the utilization of information sources by these patients and the ease of use. METHODS: A survey was conducted among outpatients undergoing chemotherapy who received medication counseling from a pharmacist at Juntendo University Hospital. Responses were gathered from 60 out of the 143 participants. Of the respondents, 96.7% had received two doses of the COVID-19 vaccine. RESULTS: Common adverse events included pain at the injection site, fever, and fatigue, which were experienced by nearly half of the respondents. Approximately 80% expressed some concern regarding vaccination, with predominant concerns about timing in the context of ongoing cancer treatment and surgery. Among the respondents, 41.7% consulted primary care physicians regarding the vaccine, with only one mentioning consultation with hospital pharmacists. Notably, primary care physicians were considered the most approachable and useful healthcare professionals. CONCLUSIONS: These results suggest that patients with cancer can safely receive the vaccine, comparable to patients without cancer. However, they still harbor concerns, even when seeking advice from primary care physicians. Few patients consulted pharmacists about vaccination, highlighting an opportunity for pharmacist intervention. Pharmacists fostering trust with patients with cancer is imperative to explore pharmacist intervention methods to promote the continued administration of COVID-19 vaccines and enhance the quality of life for them.

Evaluation of Knowledge Regarding the Use of Antibiotics among Pharmacy Undergraduates in Japan.

Antimicrobial resistance (AMR) is a global threat to human health. Education on antibiotics is essential for AMR prevention, and training should be provided for undergraduate pharmacy students. This study evaluated the knowledge regarding antibiotic use and AMR among fourth-year Japanese pharmacy students and the effect of a lecture on treating infectious diseases with antibiotics had on their knowledge. A questionnaire survey was conducted, and the responses were recorded before and after participants attended the lecture. A small subset of the prelecture survey questions was used for the postlecture survey. From a total of 540 participants, 330 and 234 responses were collected before and after the lecture, respectively. In the prelecture survey, 39.4% of the participants incorrectly answered that antibiotics can effectively treat the common cold, 13.3% had taken leftover antibiotics, and 17.3% had taken antibiotics prescribed for their family members or others. Furthermore, the prelecture survey data showed that the mean number (± standard deviation) of correct answers across the eight questions on treatment and diagnosis of infectious diseases and antibiotics was 2.21 ± 1.64. However, in the postsurvey, this figure increased to 5.00 ± 1.82. Although the lecture improved their knowledge to some extent, the results suggested that fourth-year pharmacy students have inaccurate knowledge regarding the appropriate use of antibiotics and AMR. Therefore, it is necessary to improve early-year undergraduate pharmacy education on antibiotics in Japan.

A Survey of Near-Miss Dispensing Errors in Hospital Pharmacies in Japan: DEPP-J Study-Multi-Center Prospective Observational Study-

The aim of this study was to determine the proportion of near-miss dispensing errors in hospital pharmacies in Japan. A prospective multi-center observational study was conducted between December 2018 and March 2019. The primary objective was to determine the proportion of near-miss dispensing errors in hospital pharmacy departments. The secondary objective was to determine the predictive factors for near-miss dispensing errors using multiple logistic regression analysis. The study was approved by the ethical committee at The Institute of Medical Sciences, University of Tokyo, Japan. A multi-center prospective observational study was conducted in 20 hospitals comprising 8862 beds. Across the 20 hospitals, we assessed data from 553 pharmacists and 53039 prescriptions. A near-miss dispensing error proportion of 0.87% (n = 461) was observed in the study. We found predictive factors for dispensing errors in day-time shifts: a higher number of drugs in a prescription, higher number of quantified drugs, such as liquid or powder formula, in a prescription, and higher number of topical agents in a prescription; but we did not observe for career experience level for clinical pharmacists. For night-time and weekend shifts, we observed a negative correlation of near-miss dispensing errors with clinical pharmacist experience level. We found an overall incidence of near-miss dispensing errors of 0.87%. Predictive factors for errors in night-time and weekend shifts was inexperienced pharmacists. We recommended that pharmacy managers should consider education or improved work flow to avoid near-miss dispensing errors by younger pharmacists, especially those working night or weekend shifts.

Transcatheter aspiration of a thrombus and percutaneous transluminal coronary recanalization for ST-segment elevation myocardial infarction related to coronavirus disease 2019.

Although the novel coronavirus disease 2019 (COVID-19) causes severe viral pneumonia, it has also been reported, in some cases, to co-exist with ST-segment elevation myocardial infarction. Here, we describe the case of a patient with COVID-19 and coronary risk factors for hypertension, including smoking and obesity, who developed acute myocardial infarction due to primary coronary artery thrombosis and was treated with transcatheter thrombus aspiration and percutaneous transluminal coronary recanalization (PTCR) with intracoronary urokinase administration. A large volume of thrombus was collected and thrombolysis in myocardial infarction flow grade 3 was obtained after the procedures. PTCR with or without transcatheter thrombus aspiration may be a useful treatment option. .

Clinical Effect of Adaptive Servo-Ventilation on Left Atrial Pressure During Catheter Ablation in Sedated Patients With Atrial Fibrillation.

BACKGROUND: Sedation during pulmonary vein isolation (PVI) for atrial fibrillation often provokes a decline in left atrial (LA) pressure (LAP) under atmospheric pressure and increases the risk of systemic air embolisms. This study aimed to investigate the efficacy of adaptive servo-ventilation (ASV) on the LAP in sedated patients.Methods and Results:Fifty-one consecutive patients undergoing cryoballoon PVI were enrolled. All patients underwent sedation using propofol throughout the procedure. After the transseptal puncture and the insertion of a long sheath into the LA, the LAP was measured. Then, the ASV treatment was started, and the LAP was re-measured. The LAP before and after the ASV support was investigated. Before ASV, the LAP during the inspiratory phase was significantly smaller than that during the expiratory phase (4.9±5.4 mmHg vs. 14.0±5.2 mmHg, P<0.01). The lowest LAP was -2.2±5.1 mmHg and was under 0 mmHg in 37 (73%) patients. After the ASV, the LAP during the inspiratory phase significantly increased to 8.9±4.1 mmHg (P<0.01), and lowest LAP increased to 4.7±5.9 mmHg (P<0.01). The negative lowest LAP value became positive in 30/37 (81%) patients. There were no statistical differences regarding obstructive sleep apnea (OSA), obesity, gender, or other comorbidities between patients with and without a negative lowest LAP after ASV support. CONCLUSIONS: ASV is effective for increasing the LAP above 0 mmHg and might prevent air embolisms during PVI.
