Red blood cell parameters as biomarkers of retinopathy of prematurity in preterm infants born before 30 weeks of gestation.

Retinopathy of prematurity (ROP) is a major cause of preventable blindness in preterm infants. The association between red blood cell (RBC) parameters and the development of ROP remains unclear. The objectives of the present study were to evaluate the association between RBC parameters and ROP treatment.

Association of personality and social support with subjective well-being among Japanese older adults.

Aim: Although the association between personality and health has been well documented, the interaction between personality and health risk factors is understudied. This study examined (i) the relationship between the Big Five model of personality and subjective well-being and (ii) the buffering effect of social support on the relationship between personality and subjective well-being among Japanese older adults.

Methods: The participants were 1265 adults aged 65-84 (499 men, 766 women).

[Relationship between changes in lifestyle and sleep duration due to the spread of coronavirus disease (COVID-19) in older adults: A cross-sectional study].

Objectives　In response to the spread of COVID-19, a state of emergency was declared on April 7, 2020. People were asked to stay at home unless necessary, and studies conducted in Japan and other countries have investigated the impact of these restrictions on the lives and health of older adults. While some studies have focused on sleep, a crucial aspect of the health of older adults, little is known about the relationship between sleep and various lifestyle changes experienced by older adults in Japan during the COVID-19 pandemic.

Anxiolytic effects of Enterococcus faecalis 2001 on a mouse model of colitis.

Ulcerative colitis (UC) is a refractory inflammatory bowel disease, which is known to cause psychiatric disorders such as anxiety and depression at a high rate in addition to peripheral inflammatory symptoms. However, the pathogenesis of these psychiatric disorders remains mostly unknown. While prior research revealed that the Enterococcus faecalis 2001 (EF-2001) suppressed UC-like symptoms and accompanying depressive-like behaviors, observed in a UC model using dextran sulfate sodium (DSS), whether it has an anxiolytic effect remains unclear.
