The event of the Diamond Princess, with a total of 712 (as of 17 March 2020) persons infected on the cruise ship, attracted global attention as the largest disease cluster outside China for the period 7 to 24 February 2020. Representing the Ministry of Health, Labour and Welfare, the authors were heavily engaged in the quarantine operation on the cruise ship ourselves. During the quarantine period from 5 to 23 February 2020, when the last group of the quarantined passengers left the ship, a series of measures have been conducted under the principles of i) zero deaths among all on board, ii) rapid establishment and thorough implementation of an infection control system, and iii) maintenance of health conditions and relief of anxieties among passengers and crew members. The case of Diamond Princess has implications of more than a cruise ship but deserves full scientific analysis to learn lessons from this operation as well as to study the characteristics, particularly the transmission of COVID-19.

Following a lot of reports of coronavirus disease 2019 (COVID-19) CT images, the feature of FDG-PET/CT imaging of COVID-19 was reported in several articles. Since FDG accumulates in activated inflammatory cells, FDG-PET/CT has huge potential for diagnosing and monitoring of inflammatory disease. However, FDG-PET/CT cannot be routinely used in an emergency setting and is not generally recommended as a first choice for diagnosis of infectious diseases. In this review, we demonstrate FDG-PET/CT imaging features of COVID-19, including our experience and current knowledge, and discuss the value of FDG-PET/CT in terms of estimating the pathologic mechanism.

Dyslipidemia is classified into primary and secondary types. Primary dyslipidemia is basically inherited and caused by single or multiple gene mutations that result in either overproduction or defective clearance of triglycerides and cholesterol. Secondary dyslipidemia is caused by unhealthy lifestyle factors and acquired medical conditions, including underlying diseases and applied drugs. Secondary dyslipidemia accounts for approximately 30-40% of all dyslipidemia. Secondary dyslipidemia should be treated by finding and addressing its causative diseases or drugs. For example, treatment of secondary dyslipidemia, such as hyperlipidemia due to hypothyroidism, by using statin without controlling hypothyroidism, may lead to myopathy and serious adverse events such as rhabdomyolysis. Differential diagnosis of secondary dyslipidemia is very important for safe and effective treatment. Here, we describe an overview about diseases and drugs that interfere with lipid metabolism leading to secondary dyslipidemia. Further, we show the association of each secondary dyslipidemia with atherosclerosis and the treatments for such dyslipidemia.

We investigated possible sources of newly infected patients with coronavirus disease (COVID-19) after the fourth wave in order to explore unknown sources. Retrospective chart review on all the confirmed patients with COVID-19 admitted to the National Center for Global Health and Medicine (NCGM) in Tokyo, Japan was conducted from May 22 through June 29, 2021. Among the 22 participants, 14 (64%) had a history of known high-risk infection behaviors. Of those, 12 reported that their activities involved eating and drinking. In addition, there were 24 high-risk situations, of those, 21 (88%) were related to indoor dining, and masks were not worn in 22 situations (92%). New source of infection has not been identified. In situations with a high known risk of infection, many cases were related to eating and drinking, and insufficient use of masks was evident. Raising risk awareness on infection prevention and control of COVID-19 is urgently needed.

Although Omicron appears to cause less severe acute illness than the original strain, the potential for large numbers of patients to experience long COVID is a major concern. Little is known about the recovery phase in cases of Omicron, highlighting the importance of dynamically monitor long COVID in those patients. Subjects of the current study were patients available for a three-month follow-up who were admitted from January 13 to May 22, 2020 (period of the original strain) and from January 1 to May 30, 2022 (period of Omicron). Twenty-eight-point-four percent of patients infected with the original strain had long-term symptoms of COVID-19 and 5.63% of those infected with the Omicron strain had such symptoms. The most common symptom was a cough (18.5%), followed by tightness in the chest (6.5%), in patients infected with the original strain. Fatigue (2.4%) and dyspnea (1.7%) were the most commonly reported symptoms in patients infected with the Omicron strain. The respiratory system is the primary target of SARSCoV-2. Supportive treatment is the basis for the treatment of respiratory symptoms in patients with COVID-19. Quality sleep and good nutrition may alleviate fatigue and mental issues. Further knowledge about a long-term syndrome due to Omicron needs to be discussed and assembled so that healthcare and workforce planners can rapidly obtain information to appropriately allocate resources.

Following the global call to action by the World Health Organization (WHO), the world is currently moving to eliminate cervical cancer as a public health problem. To eliminate the cancer within this century, which is defined as an age-adjusted cervical cancer incidence rate (ASIR) below 4 per 100,000 women, WHO recommends all countries to achieve "90-70-90" targets for human papilloma virus (HPV) vaccination, cervical cancer screening, and treatment of precancer and cancer by 2030. In Japan, ASIR has been rising since the late 1990s to 11.1 per 100,000 women, and this rise is particularly prominent in women of reproductive age. HPV vaccination coverage is as low as 0.3%, largely due to the Government’s ongoing suspension of proactive recommendations for the vaccine. Given the absence of centralized, population-based cervical cancer screening program and a nationwide surveillance system for systematic monitoring, the exact screening participation rate and treatment rate are difficult to estimate. A national survey suggested that only around 40% of women between the ages of 20 and 69 years underwent cervical cancer screening within the last two years. National policies and systems for HPV vaccination and screening should be updated in a more efficient way as new evidence and innovations become available. In the wake of powerful global momentum, actions must be taken now to further enhance cervical cancer control and ensure that Japanese girls and women are no longer left behind.

The battle against coronavirus disease 2019 (COVID-19) still continues three years after the onset of the pandemic, but there are concerns about the next emerging infectious disease. This study reports the practices during the initial response to COVID-19 on the cruise ship Diamond Princess and lessons learned from a nursing perspective. During these practices, one of the authors dealt with a sample collection team from the Self-Defense Forces and collaborated with the Disaster Medical Assistance Team (DMAT), Disaster Psychiatric Assistance Team (DPAT), and other teams. They mentioned the passengers' state and the distress and fatigue of the personnel assisting them. This revealed the specifics of emerging infectious diseases and their commonalities, regardless of the disaster. Results identified three crucial points: i) predicting the impact of lifestyle changes on health due to isolation and implementing preventive measures, ii) protecting individual human rights and dignity even in health emergencies, and iii) support for personnel providing assistance.

Cervical cancer is prevalent among women, with a reported 604,127 cases in 2020 worldwide. The incidence of cervical cancer has been mitigated in most high-income countries by promoting the human papilloma virus (HPV) vaccine. However, in Japan, cervical cancer is still a leading cause of mortality and the most prevalent cancer among women aged between 15 and 39. This can be attributed to the 7-year suspension of HPV vaccination recommendations by the Japanese government. A decline in vaccination coverage followed this suspension, caused by a small number of reported adverse events, resulting in a steep decline in vaccination coverage from over 70% to less than 1%. However, there have been indications of a change in trend in Japan. In 2020, a group of volunteer doctors initiated awareness-raising activities through social networking services and other platforms, and the target population that received at least one dose of the vaccine in 2020 increased to 15.9%. Additionally, in July 2020, the Japanese government approved the updated 9-valent HPV vaccine and resumed recommendations in November 2021. As a result, 30.1% of those eligible for routine HPV vaccination received at least one dose of the vaccine from April to September, 2022. However, the HPV vaccine coverage in Japan is still far from the 90% recommended by the World Health Organization, and continued communication and education on the vaccine’s benefits are necessary to achieve optimal coverage.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant has spread rapidly worldwide. We report the clinical characteristics and threshold cycle (Ct) values of the first 11 patients infected with the SARS-CoV-2 Omicron variant in Japan. All patients were younger returnees from abroad; 10 patients had received two doses of vaccine. Estimated Ct values for the 11 patients were 6.0 (95% confidence interval [CI] 4.2-7.3) days for > 30, 10.6 (95% CI 9.5-11.9) days for > 35, 15.1 (95% CI 13.6-17.6) days for > 40, and 19.7 (95% CI 17.3-23.7)days for > 45. Our results provide important insights for indicators of infection control.

Tokyo Metropolitan Area is the most populous metropolitan area in the world. While cities around the world are struggling to cope with COVID-19, the number of new positives and deaths in Tokyo has so far been relatively contained compared to other large metropolitan areas. In Japan, infection control measures do not prohibit people from moving around during a COVID-19 outbreak. However, people are not only refraining from travel and social activities at the request of the government, but are also using their own judgment to avoid risk based on information about the infectious disease. This plays an extremely important role in Japan’s infection control measures. Expectations are high in Japan for maintaining the health care system and minimizing deaths. It is necessary to steadily respond to these expectations while normalizing social functions.

Since the initial report of coronavirus disease (COVID-19) from the City of Wuhan, China in December 2019, there have been multiple cases globally. Reported here are 11 cases of COVID-19 at this hospital; all of the patients in question presented with relative bradycardia. The severity of the disease was classified into four grades. Of the patients studied, 3 with mild COVID-19 and 3 with moderate COVID-19 improved spontaneously. Lopinavir/ritonavir was administered to 3 patients with severe COVID-19 and 2 with critical COVID-19. Both patients with critical COVID-19 required mechanical ventilation and extracorporeal membrane oxygenation. Both patients with critical COVID-19 had a higher fever that persisted for longer than patients with milder COVID-19. The respiratory status of patients with critical COVID-19 worsened rapidly 7 days after the onset of symptoms. Relative bradycardia may be useful in distinguishing between COVID-19 and bacterial community-acquired pneumonia. In patients who have had a fever for > 7 days, the condition might worsen suddenly.

This study aims to evaluate the current status and perspectives on the use of Japanese long-term care (LTC) claims databases for research. We conducted a comprehensive literature search of PubMed and the Japan Medical Abstracts Society (Ichushi-Web), focusing on LTC claims data analyses published between 2000 and 2020. We summarized the study characteristics, database characteristics, and the research areas related to health services that were studied. In total, 86 journal articles (12 in Japanese and 74 in English) were included in our review. A particularly remarkable increase in the number of publications from 2016 to 2020 was observed. We extracted more publications with combined databases (n = 64) than those that only used a single source of the LTC claims databases (n = 22). More than half of the studies analyzed healthcare expenditure, healthcare utilization, and quality of care which were relevant to health services research. The most frequently mentioned limitation was the lack of validation in variables stored in the LTC claims databases. In conclusion, the LTC claims databases could serve as important sources of information for the evaluation of healthcare delivery, quality of care, and LTC policy.

World Health Organization (WHO) calls for global hepatitis strategy to eliminate viral hepatitis by 2030. Yet many high-income countries were unable to achieve HCV elimination by 2030. Apart from the tremendous efforts and resources from the governments, many non-government organizations (NGOs) have been working very hard to contribute to HCV elimination. In Hong Kong, the Center for Liver Health of The Chinese University of Hong Kong (CUHK) has been working very closely with various NGOs to educate and screen subjects who previously use intravenous drugs. In this review article, we discussed in details the New Life New Liver Program, and the barriers to HCV elimination, with special highlight the role of NGOs in overcoming the barriers.

The outbreak of coronavirus disease 2019 (COVID-19) on the cruise ship Diamond Princess docked at Yokohama, Japan was highlighted due to its number of cases in the early stage of the global epidemic when the picture of the virus itself, as well as epidemiological characteristics, were being established. We conducted an observational epidemiological study of the outbreak, focusing on a total of 403 individuals who developed a fever of ≥ 37.5°C from 20 January to 22 February 2020. Quarantine measures are also discussed with a descriptive method. Of a total of 3,711 individuals (2,031 males) from 57 countries, 2,666 (71.8%) and 1,045 (28.2%) were passengers and crew with mean age of 66.0 (range: 2-98) and 36.6 (range: 19-64), respectively. Among 403 febrile individuals, 165 passengers and 58 crew members were diagnosed as laboratory-confirmed COVID-19 cases. Until 6 February, the number of confirmed cases was three or less per day. However, distribution of thermometers on 7 February revealed 43 confirmed cases, and it then started decreasing. The outbreak was initiated from decks for passengers and expanded to areas for crew. As of 17 March, when more than14 days had passed after disembarkation of all passengers and crew, there was no report of forming a cluster of infections in Japan from them. At the time of the initiation of quarantine, the outbreak had already expanded to most of the decks from those for passengers, and the results might suggest the contribution of the set of quarantine measures in unprecedented challenges of the control operation.

In the face of COVID-19, the scientific community has rapidly come together to address this outbreak in an open and collaborative manner to support the global response to this outbreak by rapidly sharing and highlighting research data and relevant findings. COVID-19 research is being published at a furious pace. Over 6,000 articles have been published as of 20 April 2020, and at least 15 online resource centers/websites for COVID-19 have been created by publishers to enable fast and free access to the latest research, evidence, and data available. Moreover, many evidence-based guidelines for COVID-19 have been issued based on academic articles and summaries of the experiences of frontline medical personnel. Various academic medical associations are also actively sharing information and providing technical support. As an example, 93 guides/proposals/responses to COVID-19 have been issued so far by 50 medical associations in Japan. However, few publications and national situation reports have provided information on the number of infected healthcare workers (HCWs). More publications and national situation reports are urgently needed to provide scientific information to devise specific infection prevention and control measures in order to protect HCWs from infection.

Hypercoagulation and anticoagulation treatment have become new challenges in coronavirus disease 2019 (COVID-19) patients during the COVID-19 pandemic. We herein suggest an algorithm for an anticoagulation treatment with unfractionated heparin in moderate to severe COVID-19 cases in Japan, and report a case of COVID-19 pneumonia with anticoagulation treatment. Although several promising drugs for COVID-19 are being tested in clinical trials, definitive treatments have not yet been established. In this report, we demaonstrate that anticoagulation treatment with unfractionated heparin has the possibility of becoming at least a supportive treatment for COVID-19 patients.

Even after recovering from coronavirus disease 2019 (COVID-19), patients can experience prolonged complaints, referred to as "long COVID". Similar to reports in Caucasians, a follow-up study in Japan revealed that fatigue, dyspnea, cough, anosmia/dysgeusia, and dyssomnia are common symptoms. Although the precise mode of long COVID remains elusive, multiple etiologies such as direct organ damage by infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), autoimmunity, prolonged inflammatory reactions, and psychiatric impairment seem to be involved. Notably, SARS-CoV-2 is neurotropic, and viral RNA and proteins are continuously detectable in multiple organs, including the brain. Viral proteins exert a number of different toxic effects on cells, suggesting that persistent infection is a key element for understanding long COVID. Here, we first reviewed the current status of long COVID in Japan, and then summarized literature that help us understand the molecular background of the symptoms. Finally, we discuss the feasibility of vaccination as a treatment for patients with long COVID.

Due to the significant spread of a new type of coronavirus (SARS-CoV-2) infection (COVID-19) in China, the Chinese government blockaded several cities in Hubei Province. Japanese citizens lost a means of transportation to return back to Japan. The National Center for Global Health and Medicine (NCGM) helped the operation of charter flights for evacuation of Japanese residents from Hubei Province, and this article outlines our experiences. A total of five charter flights were dispatched, and the majority of returnees (793/829 [95.7%]) were handled at NCGM. A large number of personnel from various departments participated in this operation; 107 physicians, 115 nurses, 110 clerical staff, and 45 laboratory technicians in total. Several medical translators were also involved. In this operation, we conducted airborne precautions in addition to contact precautions. Eye shields were also used. The doctors collecting the pharyngeal swab used a coverall to minimize the risk of body surface contamination from secretions and droplets. Enhanced hand hygiene using alcohol hand sanitizer was performed. Forty-eight persons were ultimately hospitalized after the triage at NCGM operation, which was more than the number of persons triaged at the airport (n = 34). Of those hospitalized after NCGM triage, 8.3% (4/48 patients) ultimately tested positive for SARS-CoV-2, significantly higher than the positive rate among subjects not triaged (4/48 [8.3%] vs. 9/745 [1.2%]: p = 0.0057). NCGM participated in a large-scale operation to evacuate Japanese nationals from the COVID-19 epidemic area. We were able to establish a scheme through this experience that can be used in the future.

The report in 1981 of a cluster of cases of Kaposi sarcoma (KS) in homosexual men in New York and California was one of the earliest harbingers of the AIDS pandemic, and association of cancer with HIV/AIDS has been one of the key features of this disease since. Looking back at year 40, the development of anti-retroviral therapy markedly reduced the incidence of AIDS-related cancers that occur at low CD4 counts, and this has been one of the most impressive advances in cancer prevention over the past half-century. There have also been advances in prevention and treatment of various HIV-associated tumors. However, as AIDS patients are living longer, there has been an increase in other cancers. Cancer continues to be one of the most frequent causes of death in persons living with HIV, and further basic, translational, clinical, and epidemiologic research in this area is urgently needed.

The aim of this study is to investigate myocardial damage in recovering coronavirus disease 2019 (COVID-19) patients with high-sensitivity troponin levels (hsTnT) and echocardiography. In this single-center cohort study, 215 COVID-19 recovered patients were recruited from all over Japan between April and September 2020. Demographic characteristics, hsTnT levels, and echocardiography data were collected for 209 patients, after excluding those without serum samples or good-quality echocardiographic images. The mean (± standard deviation) age was 44 (± 12) years (range: 36-55 years), and 50.7% of the patients were males. The median time interval (interquartile range) from COVID-19 onset to post-recovery examination was 56 days (34-96 days). Seventy-four recovered patients (35.4%) had hsTnT less than detection sensitivity (< 3 pg/mL) and 135 recovered patients (64.6%) had hsTnT ≥ 3 pg/mL. Ejection fraction was more than 50% in all cases. Left ventricular global longitudinal strain (LVGLS) and right ventricular free-wall longitudinal strain (RVFWLS) were reduced in 62 (29.7%) and 8 patients (3.8%), respectively. They were significantly associated with elevated hsTnT levels. In cases with hsTnT above 5 pg/mL, the LVGLS was greatly reduced to 19.0 ± 2.2% (p < 0.001). Multivariate linear regression analysis showed that elevated hsTnT level was an independent predictor of reduced LVGLS (standardized β = -0.34; p < 0.001). In recovered COVID-19 patients, even a slight increase in hsTnT above detection sensitivity was associated with decreased LVGLS. hsTnT and echocardiography may be useful tools to detect myocardial injury in recovered COVID-19 patients.
