The significant risk factors for RH that we identified were lower body mass index, older age, and higher blood urea nitrogen at admission. No significant difference in total energy intake was seen between the RH and no RH groups, suggesting that RH may not be entirely correlated with energy intake. Precisely predicting and preventing RH is difficult, even in patients with AN who are given phosphate for prophylaxis. Thus, serum phosphate levels should be monitored for more than 5 days after admission.

Background:The Wisconsin Card Sorting Test (WCST) is a neuropsychological test to evaluate the function of the prefrontal cortex (PFC). However, inconsistent results have been reported concerning whether this task activates the PFC symmetrically or asymmetrically. Objectives:To investigate the brain activation in the PFC during the WCST, we examined blood oxygenation changes of healthy subjects by using multichannel near-infrared spectroscopy (NIRS). Methods:Subjects were 32 healthy volunteers, 18 males and 14 females. The WCST was administered using a computerized version, and the hemodynamic changes of the PFC during the WCST were measured by a 24-channel NIRS system.Results:A bilateral increase in oxygenated hemoglobin (oxyHb) was observed in the PFC in 20 subjects during the WCST. However, 5 subjects showed predominant activation on the left side and 3 subjects one on the right side. No oxyHb change was observed in 4 subjects, although they had good performances in the WCST. Conclusions:These results directly confirmed that the PFC was activated during the WCST in vivo by using the optical technique and suggested that the distribution of the activation in the PFC is different among healthy individuals.

PurposeRecently, cognitive variables such as negative and positive self-belief and thoughts have attracted much attention because they are associated with functional outcomes and quality of life (QOL). However, it is unclear how cognitive variables affect subjective and objective QOL. This study aimed to investigate the relationship of negative and positive self-belief and thoughts with subjective and objective QOL.Participants and methodsThirty-six people with schizophrenia participated in this study. Subjective and objective QOL were assessed with the Schizophrenia Quality of Life Scale (SQLS) and Quality of Life Scale (QLS), respectively. Neurocognitive function was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS). Clinical symptoms were assessed with the Positive and Negative Syndrome Scale and Calgary Depression Scale for Schizophrenia. Side effects were assessed with the Drug-induced Extrapyramidal Symptoms Scale (DIEPSS). Negative and positive self-belief and thoughts were assessed with the Defeatist Performance Belief Scale and Automatic Thoughts Questionnaire-Revised. A generalized linear model was tested, with subjective and objective QOL as the response variable and symptoms, neurocognitive function, and cognitive variables that were significantly correlated with subjective and objective QOL as explanatory variables.ResultsIn the schizophrenia group, the common objects score on the QLS was predicted by the composite BACS score, and the total QLS score was predicted by the DIEPSS score. Motivation and Energy, Psychosocial, and Symptoms and Side effects scores on the SQLS were predicted by depression and by negative automatic thought (NAT) and positive automatic thought (PAT).ConclusionOur results indicated that key targets for improving objective and subjective QOL in people with schizophrenia are side effects, neurocognitive function, depression, and NAT and PAT.
