It has not yet been established whether angiotensin II receptor blockers (ARB), statins, and multiple drugs affect the severity of COVID-19. Therefore, we herein performed an observational study on the effects of 1st- and 2nd-generation ARB, statins, and multiple drugs, on COVID-19 in patients admitted to 15 Japanese medical facilities. The results obtained showed that ARB, statins, and multiple drugs were not associated with the primary outcome (odds ratio: 1.

Although spinach is predominantly dioecious, monoecious plants with varying proportions of female and male flowers are also present. Recently, monoecious inbred lines with highly female and male conditions have been preferentially used as parents for F1-hybrids, rather than dioecious lines. Accordingly, identifying the loci for monoecism is an important issue for spinach breeding.

Background: Identifying predictive factors for coronavirus disease 2019 (COVID-19) is crucial for risk stratification and intervention. Kidney dysfunction contributes to the severity of various infectious diseases. However, the association between on-admission kidney dysfunction and the clinical outcome in COVID-19 patients is unclear.

Article Synopsis
  • - Coronavirus disease 2019 (COVID-19) is diagnosed by detecting SARS-CoV-2 RNA in samples from the nose or saliva, using specific lab techniques.
  • - Nasopharyngeal swabs should be collected by trained medical staff in full protective gear, while patients can collect saliva at home, though it may pose challenges for some individuals.
  • - A study found that oral swabs were an effective alternative for detecting SARS-CoV-2, showing a high concordance rate with nasopharyngeal swabs in patients who tested positive.

Article Synopsis
  • The study investigates the effectiveness of corticosteroids in hospitalized COVID-19 patients with varying severity, particularly those not requiring invasive ventilation.
  • Conducted across 30 hospitals in Japan, the research analyzed 1,092 patients to compare outcomes for those receiving corticosteroids versus those who did not, using adjusted data.
  • Results showed that patients receiving corticosteroids had lower odds of improvement on Day 15, but faster improvement in radiological findings and a shorter duration of invasive mechanical ventilation was noted in the corticosteroid group.

Objectives: The primary objective was to describe the characteristics of Otōri, a regionally specific drinking custom in the Miyakojima region of Okinawa, Japan, and its participants. The secondary objective was to clarify the distribution of alcohol consumption/alcohol use disorders as measured by the Alcohol Use Disorders Identification Test (AUDIT) and its association with the frequency of engagement in Otōri per month.

Design: Cross-sectional study.

Since the beginning of the coronavirus disease 2019 (COVID-19) outbreak initiated on the Diamond Princess Cruise Ship at Yokohama harbor in February 2020, we have been doing our best to treat COVID-19 patients. In animal experiments, angiotensin converting enzyme inhibitors (ACEIs) and angiotensin II type-1 receptor blockers (ARBs) are reported to suppress the downregulation of angiotensin converting enzyme 2 (ACE2), and they may inhibit the worsening of pathological conditions. We aimed to examine whether preceding use of ACEIs and ARBs affected the clinical manifestations and prognosis of COVID-19 patients.

We investigated the clinical course of individuals with 2019 novel coronavirus disease (COVID-19) who were transferred from the Diamond Princess cruise ship to 12 local hospitals. The conditions and clinical courses of patients with pneumonia were compared with those of patients without pneumonia. Among 70 patients (median age: 67 years) analyzed, the major symptoms were fever (64.

No specific and effective anti-viral treatment has been approved for COVID-19 so far. Systemic corticosteroid has been sometimes administered to severe infectious diseases combined with the specific treatment. However, as lack of the specific anti-SARS-CoV-2 drug, systemic steroid treatment has not been recommended for COVID-19.

The home care support system, newly established in 2014, is a system that always secures the hospitalization of pre-registered home care patients who need to be hospitalized. Ashigarakami Hospital has operated this system since April 2014. As of May 2018, a total of 215 people registered, and 156 people have died.

We retrospectively analyzed the backgrounds, treatment and nursing care for 96 patients aged 80 years or more with malignant tumors. Twenty of them were hospitalized on an emergency basis. Sixty patients were male and 36 were female, with a median age of 83 years (range: 80-94 years).

Spinach (Spinacia oleracea, 2n = 12) and sugar beet (Beta vulgaris, 2n = 18) are important crop members of the family Chenopodiaceae ss Sugar beet has a basic chromosome number of 9 and a cosexual breeding system, as do most members of the Chenopodiaceae ss. family. By contrast, spinach has a basic chromosome number of 6 and, although certain cultivars and genotypes produce monoecious plants, is considered to be a dioecious species.
