The coronavirus disease 2019 (COVID-19) pandemic is spreading rapidly all over the world. The Japanese government lifted the state of emergency, announced in April 2020, on May 25, but there are still sporadic clusters. Asymptomatic patients who can transmit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cause some of these clusters. It is thus urgent to investigate the seroprevalence of antibodies against SARS-CoV-2 and their neutralizing activity. We conducted a cross-sectional study of >10,000 samples at hospitals in Hyogo Prefecture, Japan.

Between August 6 and October 1, 2020, we collected samples of residual blood from the patients who visited or were admitted to five hospitals and a foundation in Hyogo. We tested the samples for antibodies against SARS-CoV-2 by electrochemiluminescence immunoassay (ECLIA) and chemiluminescent enzyme immunoassay (CLEIA). Sera that were positive by ECLIA or CLEIA were analyzed by an immunochromatographic (IC) test and neutralizing activity assay.

W seroepidemiological studies of the antibody for SARS-CoV-2, and a neutralizing activity assay is also essential.

The spread of coronavirus 2019 (COVID-19) is a serious problem all over the world. Several immunochromatography kits of the antibody for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been developed, but it is still unclear which kits have high diagnostic value. This study aims to evaluate the accuracy rate for antibody detection of each immunochromatography kit and reveal which kit has a high diagnostic value for antibody detection.

This study was carried out between 1 August 2020 and 14 October 2020 at the Association of EISEIKAI Medical and Healthcare Corporation Minamitama Hospital. Patients diagnosed with COVID-19 and approximately 30 days after symptom onset were included as the positive group. The serum SARS-CoV-2 antibodies were analysed using seven immunochromatography kits.

Twenty samples (Positive group 10 patients, Negative group 10 healthy medical workers) were included in this study. The median age of the patients was 44 years, and the median duration from symptom onset both IgM and IgG detection. Evidence from large population studies of immunochromatography kits is needed to clarify the details of diagnostic value for SARS-CoV-2.

Whether healthcare providers can secure the number of beds that may be required during the coronavirus disease 2019 (COVID-19) pandemic remains unclear. This study aimed to determine the sufficiency of the hospital beds available to the healthcare system of Yamanashi, Japan, in accommodating hospitalized and severely ill patients during the COVID-19 pandemic.

In total, 60 hospitals, with > 20 beds each, were included in this study (

= 10,684). However, beds in the psychiatric and tuberculosis wards (

= 2,295), nonoperational beds (

= 376), and beds for patients in the recovery and chronic phases (

= 3,494) were excluded. The projected occupancy rate was calculated based on the estimated number of patients, including severely ill patients requiring hospitalization during the COVID-19 pandemic. Based on the number of hospitalized patients, we created an adjusted model to calculate the mean occupancy rate of beds for each medical area in the prefecture (Model 1), which is free of areal occupancy rmated number of patients requiring hospitalization or those who are severely ill.In recent years, minimally invasive surgery for colorectal cancer has seen remarkable improvement. For the laparoscopic surgery for colon cancer, earlier postoperative recovery and reduced hospital stays can be expected compared to those for open surgery. Also, no increase in perioperative morbidity and mortality has been shown. Furthermore, long-term oncological outcomes comparable to open surgery have been obtained. Although laparoscopic surgery for rectal cancer has shown good short-term postoperative outcomes, recent randomized controlled trials could not demonstrate non-inferiority to open surgery with respect to oncological safety. Further studies are required to confirm the impact of robotic surgery on colon and rectal cancer and the appropriate indications for transanal total mesorectal excision for rectal cancer.Out-of-hospital cardiac arrest (OHCA) is a growing worldwide public health concern. Previously, Japan experienced poorer outcomes among OHCA patients than in other high-income countries. In the early 1990s, through policy changes, the Japanese government introduced a task-shift model in pre-hospital care. Some medical practices previously provided by physicians exclusively were delegated to non-physicians, including laypeople. Additionally, we initiated a nationwide data collection system for evaluation. We started a nationwide registry of OHCA patients, a paramedic system to provide advanced life-support care, and basic life-support training for laypeople. In the 2000s, the procedures paramedics could provide were expanded, laypeople were allowed to use automated external defibrillators, and the Utstein style was introduced to the national registry. Consequently, pre-hospital advanced care and bystander first-aid increased, registry-based research contributed to evidence-based practices, and-most importantly-outcomes of OHCA patients considerably improved. These Japanese experiences demonstrate that streamlining pre-hospital care, including bystander interventions and standardized data collection, can improve OHCA patient outcomes. Despite this progress, however, there still exist many issues to be addressed in response to the changing and increasing care demands within Japan's aging population.Patients with coronavirus disease 2019 (COVID-19) exhibit a wide clinical spectrum ranging from mild respiratory symptoms to critical and fatal diseases, and older individuals are known to be more severely affected. The underlying mechanism of this phenomenon is unknown. check details A neutralizing antibody against viruses is known to be important to eliminate the virus. In addition, this antibody is induced at high levels in patients with severe COVID-19, followed by a termination of virus replication. Severe COVID-19 patients exhibit high levels of cytokines/chemokines, even after the disappearance of the virus. This indicates that cytokines/chemokines play significant roles in disease severity. These findings also suggest that antiviral therapy (monoclonal antibody and/or convalescent plasma therapy) should be administered early to eliminate the virus, followed by steroid treatment after viral genome disappearance, especially in patients with severe symptoms.
