Hand hygiene (HH) compliance among health-care workers has not satisfactorily improved despite multiple educative approaches. Between October 2019 and February 2020, we performed a self-evaluation test and a direct observation for the compliance of the 5 Moments for Hand Hygiene program advocated by the World Health Organization at two Japanese hospitals. Average percentages of self-evaluated HH compliance were as follows: (i) 76.9% for "Before touching a patient," (ii) 85.8% for "Before clean/aseptic procedures," (iii) 95.9% for "After body fluid exposure/risk," (iv) 84.0% for "After touching a patient," and (v) 69.2% for "After touching patient surroundings." On the other hand, actual HH compliance was 11.7% for "Before touching a patient" and 18.0% for "After touching a patient or patient surroundings." The present study demonstrated a big gap between self-evaluation and actual HH compliance among nurses working at hospitals, indicating the need of further providing the education in infection prevention.

記述言語：英語掲載種別：研究論文（学術雑誌）

BACKGROUND: The respiratory syncytial virus (RSV) disease burden is significant, especially in infants and children with an underlying disease. Prophylaxis with palivizumab is recommended for these high-risk groups. Early recognition of a RSV epidemic is important for timely administration of palivizumab. We herein aimed to assess the correlation between national surveillance and Google Trends data pertaining to RSV infections in Japan. METHODS: The present, retrospective survey was performed between January 1, 2018 and November 14, 2021 and evaluated the correlation between national surveillance data and Google Trends data. Joinpoint regression was used to identify the points at which changes in trends occurred. RESULTS: A strong correlation was observed every study year (2018 [r = 0.87, p < 0.01], 2019 [r = 0.83, p < 0.01], 2020 [r = 0.83, p < 0.01], and 2021 [r = 0.96, p < 0.01]). The change-points in the Google Trends data indicating the start of the RSV epidemic were observed earlier than by sentinel surveillance in 2018 and 2021 and simultaneously with sentinel surveillance in 2019. No epidemic surge was observed in either the Google Trends or the surveillance data from 2020. CONCLUSIONS: Our data suggested that Google Trends has the potential to enable the early identification of RSV epidemics. In countries without a national surveillance system, Google Trends may serve as an alternative early warning system.

OBJECTIVES: While the coronavirus disease 2019 (COVID-19) pandemic has led to increased burnout among frontline healthcare workers (HCWs), little research has been done regarding the potential psychological burden among public health officials who have worked tirelessly to tackle the pandemic from an administrative perspective. This study aimed to determine the prevalence of burnout, depression, and job-related stress in Japanese public health officers amid the COVID-19 pandemic. METHODS: We conducted an anonymous, self-administered web-based cross-sectional survey including basic demographics, work-related questions, the Maslach Burnout Inventory, Patient Health Questionnaire-9, Utrecht Work Engagement Scale-3, and Brief Job Stress Questionnaire. 100 public health officers working in the public health centers (PHCs) in Okayama, Japan, answered the survey in December 2021 when the 5th surge in the number of COVID-19 was over. RESULTS: The prevalence of burnout, depression, and job-related stress was 27%, 43%, and 62%, respectively. The multivariate logistic analysis demonstrated that females, public health nurses, and those who suffered from a lack of support from their workplaces were significantly associated with psychological distress. CONCLUSIONS: While we tend to focus on mitigation plans to help alleviate burnout of frontline HCWs, more focus is needed to help public health officers, and public health nurses, in particular, to alleviate their psychological distress and job-related stress to prevent further staff shortages and secure sustainable health systems.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of nosocomial and community infections, and vancomycin (VCM) is widely recommended as a first-line therapeutic drug. Minimum inhibitory concentrations (MICs) of VCM ≤2 μg/mL are defined as susceptible, but increases in these levels, known as "VCM MIC creep" have been reported. The aim of this study was to investigate VCM MIC creep during the promotion of a national antimicrobial stewardship campaign. METHODS: We collected data from 2013 to 2020 on S. aureus isolated at the clinical microbiology laboratory at Okayama University Hospital, Japan. We calculated the annual proportions of MRSA isolation rates by MIC levels for nosocomial and community samples and estimated annual percentage changes in the antimicrobial use density of the VCM. RESULTS: Of the 1,716 MRSA isolates, no strains showed intermediate or resistant ranges of VCM MIC levels. By 2020, the proportion of MRSA with an MIC of ≤0.5 μg/mL decreased to 35.4%, while that with an MIC of 1 μg/mL increased to 64.1% over time. The annual percentage changes of the VCM antimicrobial use density significantly increased without any trend change point (average 8.1%, p = 0.035). There was no clear correlation between the VCM AUD and annual proportion of nosocomial MRSA with MIC 1 μg/mL (correlation coefficient 0.48; p value = 0.24). CONCLUSION: We demonstrated a deteriorating situation of VCM MIC creep among MRSA strains isolated at our university hospital during the national antimicrobial stewardship campaign.

Netherton's syndrome, a rare congenital disorder, is clinically characterized by chronic dermatologic disorders such as ichthyosiform erythroderma and ichthyosis linearis circumflexa. Curable treatment is yet to be established, and corticosteroid ointment is required to maintain good dermatological condition. Because of the permanent skin barrier impairment, patients with Netherton's syndrome are considered to be vulnerable to cutaneous infections. However, its clinical characteristics are yet to be elucidated due to the limited number of reported cases. Herein, we describe the clinical course of a patient who developed persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. A 19-year-old Japanese woman who had been diagnosed with Netherton's syndrome in her infancy and had been applying topical corticosteroid agents all over her body since her then, was referred to our hospital because of persistent MRSA bacteremia and secondary adrenal insufficiency. The patient was diagnosed with a central line-associated bloodstream infection and was appropriately treated with antibiotics and corticosteroid therapies. We assume that the damaged skin barrier due to the congenital dermatological disorder causes a disruption in the normal bacterial flora of the skin, leading to the invasion of harmful bacteria, such as S. aureus. In addition, internal (humoral immunodeficiency by decreased antibody against bacterial polysaccharide antigens) and external (prolonged and systemic use of corticosteroid ointment) factors bring about an immunodeficiency state in such patients. We highlight that in the absence of radical treatment, clinicians need to recognize that patients with Netherton's syndrome are vulnerable to bacterial infections owing to the mixture of immunosuppressive factors.

We aimed to compare the differences in testing performance of extraction-based polymerase chain reaction (PCR) assays, elution-based direct PCR assay, and rapid antigen detection tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We used nasopharyngeal swab samples of patients with coronavirus disease 2019 (COVID-19). We used the MagNA Pure 24 System (Roche Diagnostics K.K.) or magLEAD 12gC (Precision System Science Co., Ltd.) for RNA extraction, mixed the concentrates with either the LightMix Modular SARS-CoV PCR mixture (Roche Diagnostics K.K.) or Takara SARS-CoV-2 direct PCR detection kit (Takara Bio Inc.), and amplified it using COBAS® z480 (Roche Diagnostics K.K.). For elution-based PCR, we directly applied clinical samples to the Takara SARS-CoV-2 direct PCR detection kit before the same amplification step. Additionally, we performed Espline SARS-CoV-2 (Fuji Rebio Co., Ltd.) for rapid diagnostic test (RDT), and used Lumipulse SARS-CoV-2 antigen (Fuji Rebio Co., Ltd.) and Elecsys SARS-CoV-2 antigen (Roche Diagnostics K.K.) for automated antigen tests (ATs). Extraction-based and elution-based PCR tests detected the virus up to 214-216 and 210 times dilution, respectively. ATs remained positive up to 24-26 times dilution, while RDT became negative after 22 dilutions. For 153 positive samples, positivity rates of the extraction-based PCR assay were 85.6% to 98.0%, while that of the elution-based PCR assay was 73.2%. Based on the RNA concentration process, extraction-based PCR assays were superior to elution-based direct PCR assays for detecting SARS-CoV-2.

Background and Objectives: COVID-19 can be serious not only in the acute phase but also after the acute phase and some patients develop ME/CFS. There have been few studies on patients with long COVID in whom ME/CFS was diagnosed by physicians based on standardized criteria after examinations and exclusion diagnosis and not based on only subjective symptoms. The purpose of this study was to elucidate the detailed characteristics of ME/CFS in patients with long COVID. Materials and Methods: A retrospective descriptive study was performed for patients who visited a COVID-19 aftercare clinic established in Okayama University Hospital during the period was from February 2021 to April 2022. Results: Clinical data were obtained from medical records for 281 patients, and 279 patients who met the definition of long COVID were included. The overall prevalence rate of ME/CFS diagnosed by three sets of ME/CFS criteria (Fukuda, Canadian and IOM criteria) was 16.8% (48.9% in male and 51.1% in females). The most frequent symptoms in ME/CFS patients were general fatigue and post-exertional malaise (89.4% of the patients), headache (34.0%), insomnia (23.4%), dysosmia (21.3%) and dysgeusia (19.1%). Dizziness, chest pain, insomnia and headache were characteristic symptoms related to ME/CFS. The male to female ratio in ME/CFS patients was equal in the present study, although ME/CFS was generally more common in women in previous studies. Given that patients with ME/CFS had more severe conditions in the acute phase of COVID-19, the severity of the acute infectious state might be involved in the pathophysiology of ME/CFS. Conclusions: The prevalence rate of ME/CFS and the characteristic sequelae in the long COVID condition were revealed in this study.

AIM: Amid the global aging, an establishment of healthcare policies for the aged population is a common issue to be addressed. However, few studies on centenarians have reported place and cause of death (PoD and CoD, respectively) as indicators of end-of-life care quality. This study aimed to analyze trends in PoD and CoD among centenarians in Japan. METHODS: Data from death certificates from Japanese vital statistics were analyzed; 205 513 deaths occurred among centenarians (aged ≥100 years) in Japan during the period from 2006 to 2016. PoD prevalence was calculated for each CoD. Trends in PoD prevalence were analyzed using the Joinpoint regression model. Changing points, annual percentage changes, and average annual percentage changes (AAPCs) were calculated to examine trends. RESULTS: The number of deaths more than doubled from 10 340 in 2006 to 26 427 in 2016. PoDs were composed of hospitals (52.7%), nursing homes (31.4%), own homes (13.6%) and others (2.2%). Dementia and old age increased rapidly as CoD. Proportions of hospital and home deaths decreased, with AAPCs of -2.3% (95% confidence interval [CI], -2.6 to -1.9) and -2.3% (95% CI, -3.2 to -1.4), respectively. Conversely, the proportion of deaths in nursing homes rapidly increased, with an AAPC of 6.8% (95% CI, 6.0-7.7). CONCLUSIONS: The results revealed changes in PoD among centenarians in Japan. Understanding these transitions is indispensable for health policy in aging societies. Geriatr Gerontol Int 2022; ••: ••-••.

Evidence regarding treatment for the acute phase of COVID-19 has been accumulating, but specific treatment for long COVID/post-COVID-19 condition has not yet been established. Treatment with herbal medicine might be one treatment option for long COVID, but there has been little research on the effectiveness of herbal medicine for long COVID. The aim of this study was to clarify the prescription patterns of Kampo medicines, which are herbal medicines that originated in China and were developed in Japan, for the treatment of general fatigue due to long COVID. A retrospective descriptive study was performed for patients who visited a COVID-19 aftercare clinic established in Okayama University Hospital during the period from Feb 2021 to Dec 2021 with a focus on symptoms accompanying general fatigue and prescriptions of Kampo medicine. Among the clinical data obtained from medical records of 195 patients, clinical data for 102 patients with general fatigue and accompanying symptoms were analyzed. The patients had various symptoms, and the most frequent symptoms accompanying general fatigue were dysosmia, dysgeusia, headache, insomnia, dyspnea, and hair loss. Prescriptions of Kampo medicine accounted for 24.1% of the total prescriptions (n = 609). The most frequently prescribed Kampo medicine was hochuekkito (71.6%) and other prescribed Kampo medicines were tokishakuyakusan, ryokeijutsukanto, juzentaihoto, hangekobokuto, kakkonto, ninjin'yoeito, goreisan, rikkunshito, and keishibukuryogan. Since the pathophysiology of general fatigue after an infectious disease is, in general, considered a qi deficiency in Kampo medicine, treatments with such compensation agents can be the major prescription as a complement for the qi. In conclusion, Kampo medicine can be one of the main pharmacological treatments for long COVID accompanying general fatigue.
