RESUMEN
The WHO recently proposed a new indicator for judging the appropriateness of antimicrobial selection according to the AWaRe classification. Although macrolides are often administered for long-term macrolide therapy, the impact of this therapy on the indicator remains unclear. This study examined the impact of this therapy on the indicator for outpatient oral antimicrobial use. Using the JMDC claims database, outpatients who were prescribed an oral antimicrobial at least once between January and December 2022 (n = 2.66 million) were included in the study. The ratio of patient numbers and antimicrobial usage (AMU) were calculated based on age group (<15, 15-64, and ≥65 years) and prescription days (1-15, 16-30, 31-60, 61-90, and ≥91 days), and AMU of each drug was corrected for defined daily doses and classified according to the AWaRe. Patients with chronic airway disease for whom macrolides were prescribed for 91 days and more were defined as long-term macrolide therapy. Macrolides accounted for more than 30 % of total oral AMU in all age groups. In the elderly, 11.2 % of patients were prescribed macrolides for 91 days or more, accounting for 66.4 % of macrolide use. With regard to diseases that were associated with macrolide prescriptions, the percentage of patients prescribed for chronic airway diseases increased as the number of days of prescription increased. These results suggest that the impact of long-term macrolide therapy should be considered when assessing the appropriateness of outpatient oral AMU according to the AWaRe classification.
RESUMEN
PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic exhibited several different waves threatening global health care. During this pandemic, medical resources were depleted. However, the kind of medical resources provided to each wave was not clarified. This study aimed to examine the characteristics of medical care provision at COVID-19 peaks in preparation for the next pandemic. METHODS: Using medical insurance claim records in Japan, we examined the presence or absence of COVID-19 infection and the use of medical resources for all patients monthly by age group. RESULTS: The wave around August 2021 with the Delta strain had the strongest impact on the working population in terms of hospital admission and respiratory support. For healthcare providers, this peak had the highest frequency of severely ill patients. In the subsequent wave, although the number of patients with COVID-19 remained high, they were predominantly older adults, with relatively fewer patients receiving intensive care. CONCLUSIONS: In future pandemics, we should refer to the wave around August 2021 as a situation of medical resource shortage resulting from the COVID-19 pandemic.

Achieving spin-pinning at the interface of hetero-bilayer ferromagnet/antiferromagnet structures in conventional exchange bias systems can be challenging due to difficulties in interface control and the weakening of spin-pinning caused by poor interface quality. In this work, we propose an alternative approach to stabilize the exchange interaction at the interface of an uncompensated antiferromagnet by utilizing a gradient of interlayer exchange coupling. We demonstrate this exchange interaction through a designed field training protocol in the odd-layer topological antiferromagnet MnBi2Te4. Our results reveal a remarkable field-trained exchange bias of up to ~ 400 mT, which exhibits high repeatability and can be easily reset by a large training field. Notably, this field-trained exchange bias effect persists even with zero-field initialization, presenting a stark contrast to the traditional field-cooled exchange bias. The highly tunable exchange bias observed in this single antiferromagnet compound, without the need for an additional magnetic layer, provides valuable insight into the exchange interaction mechanism. These findings pave the way for the systematic design of topological antiferromagnetic spintronics.
RESUMEN
Primary ciliary dyskinesia (PCD) is a hereditary disease caused by pathogenic variants in genes associated with motile cilia. Some variants responsible for PCD are reported to be ethnic-specific or geographical-specific. To identify the responsible PCD variants of Japanese PCD patients, we performed next-generation sequencing of a panel of 32 PCD genes or whole-exome sequencing in 26 newly identified Japanese PCD families. We then combined their genetic data with those from 40 Japanese PCD families reported previously, for an overall analysis of 66 unrelated Japanese PCD families. We conducted Genome Aggregation Database and TogoVar database analyses to reveal the PCD genetic spectrum of the Japanese population and compare with other ethnic groups worldwide. We identified 22 unreported variants among the 31 patients in the 26 newly identified PCD families, including 17 deleterious variants estimated to cause lack of transcription or nonsense-mediated mRNA decay and 5 missense mutations. In all 76 PCD patients from the 66 Japanese families, we identified 53 variants on 141 alleles in total. Copy number variation in DRC1 is the most frequent variant in Japanese PCD patients, followed by DNAH5 c.9018C>T. We found 30 variants specific to the Japanese population, of which 22 are novel. Furthermore, 11 responsible variants in the Japanese PCD patients are common in East Asian populations, while some variants are more frequent in other ethnic groups. In conclusion, PCD is genetically heterogeneous between different ethnicities, and Japanese PCD patients have a characteristic genetic spectrum.

We herein report a three-year-old boy with septic pulmonary embolism caused by Tsukamurella paurometabola bacteremia during chemotherapy for rhabdomyosarcoma. During the interval of chemotherapy, the patient was temporarily discharged with a peripherally inserted central venous catheter but was re-admitted to the hospital with a fever on the same day. A blood culture taken at the time of re-admission showed T. paurometabola. The patient had a persistent fever, and computed tomography performed on the ninth day showed septic pulmonary embolism. We stress the importance of being aware of the possibility of septic pulmonary embolism in patients with Tsukamurella bacteremia.

The aim was to investigate the clinical characteristics of coronavirus disease 2019 (COVID-19) patients who were admitted to a designated hotel, and to clarify the risk factors for hospitalization of such patients with clinical deterioration. The medical records of COVID-19 patients who were admitted to the designated hotel in Mie Prefecture, Japan, between August 2020 and September 2021 were reviewed retrospectively. Of the 1,087 COVID-19 patients who were admitted to the designated hotel, 936 patients (32.1± 12.8 years, 61.3% male) were recruited after excluding patients under the age of 15 years (n = 33), those admitted from the hospital (n = 111, 10.2%), COVID-19 vaccinated patients (n = 4, 0.4%), and those who were discharged to their own home due to social disorders (n = 3). During the study period, 884 patients (94.4%) were discharged to their own home with improving symptoms, whereas 52 patients (5.6%) were hospitalized for a deteriorating clinical condition. The logistic regression analyses showed that older age (≥ 40 years), higher body mass index (≥ 25 kg/m2), hypertension were the risk factors for hospitalization. As the new risk scale score based on the results of the odds ratios increased, the hospitalization rate increased significantly: 2.0% at 0-1 points, 9.7% at 2-3 points, and 28.8% at 4-5 points (p < 0.001). None of the 52 hospitalized patients died, and none developed serious complications from COVID-19 after hospitalization. In conclusion, the designated accommodation program for COVID-19 patients was safe, especially for those with a low risk for hospitalization.

BACKGROUND: Coronary artery perforation is one of the most feared and common complications of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: To assess the usefulness of the recently developed PROGRESS-CTO (NCT02061436) perforation risk score in independent cohorts. Individual patient-level data pooled analysis of three registries was performed. RESULTS: Of the 4566 patients who underwent CTO PCI at 25 centers, 196 (4.2%) had coronary artery perforation. Patients with perforations were older (69 ± 10 vs. 65 ± 10, p < 0.001), more likely to be women (19% vs. 13%, p = 0.009), more likely to have a history of prior coronary artery bypass graft (34% vs. 20%, p < 0.001), and unfavorable angiographic characteristics such as blunt stump (62% vs. 48%, p < 0.001), proximal cap ambiguity (52% vs. 34%, p < 0.001), and moderate-severe calcification (60% vs. 49%, p = 0.002). Technical success was lower in patients with perforations (73% vs. 88%, p < 0.001). The area under the receiver operating characteristic curve of the PROGRESS-CTO perforation risk model was 0.76 (95% confidence interval [CI], 0.72-0.79), with good calibration (Hosmer-Lemeshow p = 0.97). We found that the CTO PCI perforation risk increased with higher PROGRESS-CTO perforation scores: 0.3% (score 0), 2.3% (score 1), 3.1% (score 2), 5.5% (score 3), 7.5% (score 4), 14.6% (score 5). CONCLUSION: Given the good discriminative performance, calibration, and the ease of calculation, the PROGRESS-CTO perforation score may facilitate assessment of the risk of perforation in patients undergoing CTO PCI.
RESUMEN
Coronavirus disease 2019 (COVID-19) associated myocardial injury was caused by various mechanisms. We herein describe 2 cases presenting different types of myocardial injury due to Omicron variant. In both patients, diffuse reduced left ventricular (LV) wall motion in transthoracic echocardiography, electrocardiographic abnormality, and elevated myocardial enzymes were demonstrated. In addition, cardiovascular magnetic resonance (CMR) findings fulfilled the 2018 Lake Louise Criteria (LLC) for myocarditis. However, histological findings in 1 patient showed inflammatory cell infiltration with myocyte degeneration, while those in the other showed interstitial edema without inflammatory cell infiltration. Histological findings were crucial for a differential diagnosis of myocardial injury due to Omicron variant.

BACKGROUND: Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is associated with a considerable risk of complications, and risk stratification is of utmost importance. AIMS: To assess the clinical usefulness of the recently developed PROGRESS-CTO (NCT02061436) complication risk scores in an independent cohort. METHODS: Individual patient data pooled analysis of 3 registries was performed. RESULTS: Of the 4569 patients who underwent CTO PCI, 102 (2.2%) had major adverse cardiovascular events (MACE). Patients with MACE were older (69 ± 11 vs. 65 ± 10, p < 0.001), more likely to have a history of prior coronary artery bypass graft surgery, and unfavorable angiographic characteristics J-CTO score (2.4 ± 1.2 vs. 2.1 ± 1.3, p = 0.007), including blunt stump (59% vs. 49%, p = 0.047). Technical success was lower in patients with MACE (59% vs. 86%, p < 0.001). The area under the receiver operating characteristic curve of the PROGRESS-CTO complication risk models were as follows: MACE 0.72 (95% confidence interval [CI], 0.67-0.76), mortality 0.73 (95% CI, 0.61-0.85), and pericardiocentesis 0.69 (95% CI, 0.62-0.77) in the validation dataset. The observed complication rates increased with higher PROGRESS-CTO complication scores. The PROGRESS-CTO MACE score showed good calibration in this external cohort, with MACE rates similar to the original study: 0.7% (score 0-1), 1.5% (score 2), 2.2% (score 3), 3.8% (score 4), 4.9% (score 5), 5.8% (score 6-7). CONCLUSION: Given the good discriminative performance, calibration, and ease of calculation, the PROGRESS-CTO complication scores could help assess the risk of complications in patients undergoing CTO PCI.

Coronary artery perforation is one of the most common and feared complications of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We evaluated the utility of the recently presented OPEN-CLEAN (Coronary artery bypass graft, Length of occlusion, Ejection fraction, Age, calcificatioN) perforation score in an independent multicenter CTO PCI dataset. Of the 2,270 patients who underwent CTO PCI at 7 centers, 150 (6.6%) suffered coronary artery perforation. Patients with perforations were older (69 ± 10 vs 65 ± 10, p <0.001), more likely to be women (89% vs 82%, p = 0.010), more likely to have history of previous coronary artery bypass graft (38% vs 20%, p <0.001), and unfavorable angiographic characteristics such as blunt stump (64% vs 42%, p <0.001), proximal cap ambiguity (51% vs 33%, p <0.001), and moderate-severe calcification (57% vs 43%, p = 0.001). Technical success was lower in patients with perforations (69% vs 85%, p <0.001). The area under the receiver operating characteristic curve of the OPEN-CLEAN perforation risk model was 0.74 (95% confidence interval 0.68 to 0.79), with good calibration (Hosmer-Lemeshow p = 0.72). We found that the CTO PCI perforation risk increased with higher OPEN-CLEAN scores: 3.5% (score 0 to 1), 3.1% (score 2), 5.3% (score 3), 7.1% (score 4), 11.5% (score 5), 19.8% (score 6 to 7). In conclusion, given its good performance and ease of preprocedural calculation, the OPEN-CLEAN perforation score appears to be useful for quantifying the perforation risk for patients who underwent CTO PCI.

Background: Even though hospital admissions for acute myocardial infarction (AMI) decreased globally during the COVID-19 pandemic in early 2020, limited information is available on subsequent demographic trends in the number of cases and management of AMI through the first 12 months of the COVID-19 pandemic. MethodsâandâResults: We assessed demographic trends, patient characteristics, and AMI outcomes (n=730) during the first 12 months of the COVID-19 pandemic and compared them with corresponding months during the control period (February 2016-January 2020; n=2,742) using data from the Mie ACS Registry. Although a 25.8% reduction in hospitalizations for AMI was observed in the 3 months following the declaration of a state of emergency (47.7 vs. 64.3/month; P=0.002), the total number of AMI patients was similar between the 12-month COVID-19 and control periods (60.8 vs. 57.2/month; P=0.58). The number of patients requiring direct ambulance transport was lower in the first half of the COVID-19 than control period (44.4% vs. 51.5; P=0.028). In-hospital mortality was higher in the second half of the COVID-19 than control period (8.9% vs. 5.8%; P=0.032). Conclusions: Through the first 12 months of the COVID-19 pandemic, the number of AMI cases was similar to that in previous years. The COVID-19 pandemic changed the behavior of AMI patients and both pre- and in-hospital medical management, which significantly affected the severity and prognosis of AMI.
RESUMEN
Primary ciliary dyskinesia (PCD) is a rare hereditary disease. We herein report two sisters in their 20s with suspected PCD. They were both born at full term and did not have situs inversus. Chest computed tomography showed similar signs of bronchiectasis in both siblings. Genetic examinations of the family confirmed that the sisters both harbored a homozygous variant in the growth-arrest-specific 2-like 2 (GAS2L2) gene. This is the third report of a family with PCD caused by a GAS2L2 variant.

The evaluation indexes of antimicrobial use (AMU) in sub-prefectural regions have not been established because these regional units are susceptible to the effects of population inflows and outflows. We defined the difference in AMU calculated each year as a new evaluation index and compared the AMU of secondary medical areas with those already reported for Japan and each prefecture. Patients/1000 inhabitants/day (PID) for oral antibiotics in 2013 and 2016 were calculated using the National Database of Health Insurance Claims and Specific Health Checkups. ΔPID was defined as the difference between the PIDs in 2013 and 2016. Differences in AMUs for Japan and prefectures that have already been published were also calculated, and the concordance rate with ΔPID in each secondary medical area was evaluated. Antibiotics and age groups with less than 50% concordance between secondary medical area and previously reported AMU changes were observed. This revealed that even at the secondary medical area level, which is more detailed than the prefectural level, the AMU changes were not consistent. Therefore, in order to appropriately promote measures against antimicrobial resistance, we suggest the necessity of not only surveying AMU at the national or prefectural levels but also examining sub-prefectural trends in AMU.
RESUMEN
BACKGROUND: The prevalence of deep venous thrombosis (DVT) among hospitalized psychiatric patients after coronavirus disease 2019 (COVID-19) infection remains unclear.MethodsâandâResults:We retrospectively investigated the prevalence of proximal DVT after COVID-19 infection among 50 hospitalized patients in a Japanese psychiatric hospital that in which a COVID-19 cluster developed between August and September 2020. The prevalence of proximal DVT was 10.0%. Patients with proximal DVT had a lower body weight and higher maximum D-dimer levels and International Medical Prevention Registry on Venous Thromboembolism (IMPROVE) VTE scores. CONCLUSIONS: After COVID-19 infection, hospitalized psychiatric patients are at high risk of DVT and should be carefully followed up.

INTRODUCTION: We previously showed the trend of antimicrobial use (AMU) for Clostridioides (Clostridium) difficile infection (CDI) using sales data. However, the details of the prescribing medical institutions and regional characteristics are unknown. Therefore, the purpose of this study was to clarify the details of the medical institutions where antibiotics for CDI were prescribed, and evaluate the AMU for CDI and the regional characteristics. METHODS: Antibiotics for CDI, including oral vancomycin (VCM), oral metronidazole (MNZ), and intravenous (IV) MNZ, were collected from the National Database of Health Insurance Claims and Specific Health Checkups (NDB) between 2013 and 2016. The PID (patients/1000 inhabitants/day) was used as an evaluation index for AMU. The PID was calculated using the claim types: inpatient, outpatient, dental, and pharmacy. The PID of each prefecture was calculated for inpatient claims in 2016. RESULTS: The AMU of oral VCM and IV MNZ were observed mainly in the inpatient claims. For oral MNZ, the total AMU in the outpatient and pharmacy claims accounted for approximately 80% per year throughout the study period. For inpatient claims of each prefecture in 2016, the PID of the antibiotics used for CDIs was approximately 3.5 times the difference between the highest and lowest prefectures. CONCLUSIONS: The AMU for CDI that takes into account the purpose of use was clarified by using the information of the prescribed medical institutions that were included in the NDB. Oral MNZ was used frequently in outpatients, and attention should be paid to the acquisition of resistance.

PURPOSE: Antimicrobial use (AMU) is estimated at the national level by using sales data (S-AMU) or insurance claims data (C-AMU). However, these data might be biased by generic drugs that are not sold through wholesalers (direct sales) and therefore not recorded in sales databases, or by claims that are not submitted electronically and therefore not stored in claims databases. We evaluated these effects by comparing S-AMU and C-AMU to ascertain the characteristics and limitations of each kind of data. We also evaluated the interchangeability of these data by assessing their relationship. METHODS: We calculated monthly defined daily doses per 1,000 inhabitants per day (DID) using sales and claims data from 2013 to 2017. To assess the effects of non-electronic claim submissions on C-AMU, we evaluated trends in the S-AMU/C-AMU ratio (SCR). To assess the effects of direct sales of S-AMU, we divided AMU into generic and branded drugs and evaluated each SCR in terms of oral versus parenteral drugs. To assess the relationship between S-AMU and C-AMU, we created a linear regression and evaluated its coefficient. RESULTS: Median annual SCRs from 2013 to 2017 were 1.046, 0.993, 0.980, 0.987, and 0.967, respectively. SCRs dropped from 2013 to 2015, and then stabilized. Differences in SCRs between branded and generic drugs were significant for oral drugs (0.820 vs 1.079) but not parenteral drugs (1.200 vs 1.165), suggesting that direct sales of oral generic drugs were omitted in S-AMU. Coefficients of DID between S-AMU and C-AMU were high (generic, 0.90; branded, 0.84) in oral drugs but relatively low (generic, 0.32; branded, 0.52) in parenteral drugs. CONCLUSIONS: The omission of direct sales information and non-electronically submitted claims have influenced S-AMU and C-AMU information, respectively. However, these data were well-correlated, and it is considered that both kinds of data are useful depending on the situation.

OBJECTIVES: The authors sought to examine the outcomes of percutaneous coronary intervention (PCI) for in-stent restenosis (ISR) chronic total occlusions (CTOs). BACKGROUND: The outcomes of PCI for ISR CTOs have received limited study. METHODS: The authors examined the clinical and angiographic characteristics and procedural outcomes of 11,961 CTO PCIs performed in 11,728 patients at 107 centers in Europe, North America, Latin America, and Asia between 2012 and 2020, pooling patient-level data from 4 multicenter registries. In-hospital major adverse cardiovascular events (MACE) included death, myocardial infarction, stroke, and tamponade. Long-term MACE were defined as the composite of all-cause death, myocardial infarction, and target vessel revascularization. RESULTS: ISR represented 15% of the CTOs (n = 1,755). Patients with ISR CTOs had higher prevalence of diabetes (44% vs. 38%; p < 0.0001) and prior coronary artery bypass graft surgery (27% vs. 24%; p = 0.03). Mean J-CTO (Multicenter CTO Registry in Japan) score was 2.32 ± 1.27 in the ISR group and 2.22 ± 1.27 in the de novo group (p = 0.01). Technical (85% vs. 85%; p = 0.75) and procedural (84% vs. 84%; p = 0.82) success was similar for ISR and de novo CTOs, as was the incidence of in-hospital MACE (1.7% vs. 2.2%; p = 0.25). Antegrade wiring was the most common successful strategy, in 70% of ISR and 60% of de novo CTOs, followed by retrograde crossing (16% vs. 23%) and antegrade dissection and re-entry (15% vs. 16%; p < 0.0001). At 12 months, patients with ISR CTOs had a higher incidence of MACE (hazard ratio: 1.31; 95% confidence interval: 1.01 to 1.70; p = 0.04). CONCLUSIONS: ISR CTOs represent 15% of all CTO PCIs and can be recanalized with similar success and in-hospital MACE as de novo CTOs.

PURPOSE: Regional-level measures can complement national antimicrobial stewardship programs. In Japan, sub-prefectural regions called secondary medical areas (SMAs) provide general inpatient care within their borders, and regional antimicrobial stewardship measures are frequently implemented at this level. There is therefore a need to conduct antimicrobial use (AMU) surveillance at this level to ascertain antimicrobial consumption. However, AMU estimates are generally standardized to residence-based nighttime populations, which do not account for population mobility across regional borders. We examined the impact of population in/outflow on SMA-level AMU estimates by comparing the differences between standardization using daytime and nighttime populations. METHODS: We obtained AMU information from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. AMU was quantified at the prefectural and SMA levels using the number of defined daily doses (DDDs) divided by (a) 1,000 nighttime population per day or (b) 1,000 daytime population per day. We identified and characterized the discrepancies between the two types of estimates at the prefectural and SMA levels. RESULTS: The national AMU was 17.21 DDDs per 1,000 population per day. The mean (95% confidence interval) prefectural-level DDDs per 1,000 nighttime and daytime population per day were 17.27 (14.10, 20.44) and 17.41 (14.30, 20.53), respectively. The mean (95% confidence interval) SMA-level DDDs per 1,000 nighttime and daytime population per day were 16.12 (9.84, 22.41) and 16.41 (10.57, 22.26), respectively. The nighttime population-standardized estimates were generally higher than the daytime population-standardized estimates in urban areas, but lower in the adjacent suburbs. Large differences were observed in the main metropolitan hubs in eastern and western Japan. CONCLUSION: Regional-level AMU estimates, especially of smaller regions such as SMAs, are susceptible to the use of different populations for standardization. This finding indicates that AMU standardization based on population values is not suitable for AMU estimates in small regions.

INTRODUCTION: Anti-methicillin-resistant Staphylococcus aureus (MRSA) agents have different doses and administration periods. Thus, it is difficult to evaluate antimicrobial use (AMU) of anti-MRSA agents using defined daily doses per 1000 inhabitants per day (DID) or days of therapy per 1000 inhabitants per day (DOTID). This study aimed to evaluate the relationship between anti-MRSA agent use and resistant bacteria using the number of patients per 1000 inhabitants per day (PID) as an alternative index of AMU. METHODS: AMU data for anti-MRSA agents were collected from the National Database of Health Insurance Claims and Specific Health Checkups (NDB) in 2016. The relationship between PID and DID or DOTID was evaluated. The number of patients with MRSA isolated was obtained from Japan Nosocomial Infections Surveillance, and their correlation with PID was analyzed. The rate of anti-MRSA agent use in each prefecture was investigated. RESULTS: PID showed a significant linear relationship with both DID and DOTID (all p < 0.0001). PID was significantly correlated with the number of patients with MRSA isolated. Additionally, the rate of anti-MRSA agent use was markedly different in each region. CONCLUSIONS: PID is not affected by doses and administration periods, and thus may be an alternative index for the selective pressure of antibiotics. Evaluating AMU using PID based on NDB data will help in the development of effective antimicrobial resistance measures.

Most cases of mediastinal abscess occur as a postoperative complication of a thoracic surgical procedure or following trauma. The most common causative microorganism is Staphylococcus aureus, but it can be rarely caused by unusual microorganisms, such as Gemella species. These are relatively difficult-to-identify commensal microorganisms of the upper respiratory and gastrointestinal tracts and may cause several infections. A 66-year-old man was diagnosed with Gemella bergeri mediastinal abscess by the molecular detection of bacterial genes. He was successfully treated with penicillin antibiotic for eight weeks. To our knowledge, this is the first case report of mediastinal abscess caused by G. bergeri.
