RESUMEN
AIM: Psychiatric disturbances are the major adverse effects of corticosteroids. There are no consistent conclusions regarding changes in steroid dosage and the incidence of psychiatric conditions, due in part to the lack of consistent evaluation criteria. The purpose of this research was to determine the incidence and dose-dependency of psychiatric conditions as assessed by trained psychiatrists. METHODS: A retrospective chart review was conducted at a university hospital in Japan. We identified inpatients receiving oral prednisolone treatment, who were referred to the consultation-liaison psychiatry team from April 2015 to March 2018. Patients were divided into high-dose (≥0.5 mg/kg/day) and low-dose (<0.5 mg/kg/day) groups. We investigated the associations between steroid dosage and incidence of psychiatric conditions. RESULTS: A total of 93 patients (35 in the high-dose group, 58 in the low-dose group) were included. Various psychiatric conditions, such as insomnia, delirium, depression, and psychosis, occurred during steroid therapy. The most common condition was insomnia (72%). We observed no significant differences in the patient background characteristics and the incidence of most psychiatric conditions between the high-dose and low-dose groups. However, there were more patients with delirium in the low-dose group than in the high-dose group. CONCLUSIONS: Based on the accurate assessment of psychiatric conditions by psychiatrists, our analysis suggests that, among inpatients referred to a consultation-liaison psychiatry team, the incidence of psychiatric conditions, with the exception of delirium, is independent of the dose of oral prednisolone.

As a forage source for total mixed ration (TMR) silage production, locally produced crop silage is now used in addition to imported hay. This type of TMR ensiling is regarded as a two-step fermentation process; hence, a survey was carried out to determine whether the bacteria in crop silage affect the subsequent TMR ensiling. Fermentation product contents and bacterial community were determined for TMR silage and its ingredient silages collected in August, October and November. August product contained corn, sorghum and Italian ryegrass silages, October product had wheat silage exclusively and November product did not include any crop silages. Acetic acid, lactic acid, 2,3-butanediol and ethanol were predominant fermentation products in corn, sorghum, Italian ryegrass and wheat silages, respectively. Robust lactic acid fermentation was seen in TMR silage, even if acetate-type and alcohol-type silages were mixed as ingredients. The finding that bacterial community of the TMR silage appeared unrelated to those of ingredient silage supported this. Silages of various fermentation types can therefore be formulated without interfering with lactate-type fermentation in TMR silage.
