RESUMO
Background: Psychiatric interventions may be required during pregnancy. In the aspect of the management of psychiatric symptoms and the consideration of the need for pharmacotherapy, possibly to manage the effects on the fetus, pregnant women with mental disorders are considered high risk as other physical illnesses. Objective: We investigated the characteristics of pregnant women with psychiatric disorders compared with high-risk pregnant women with physical illnesses at our university hospital and the effects of psychotropic drug use on pregnant women with mental disorders and their children. Materials and Methods: In a multivariate analysis of 1282 pregnant women, excluding those with multiple pregnancies who gave birth at our hospital between January 2017 and the end of December 2019, we evaluated the effects of mental disorders and the use of psychotropic drugs throughout at least the third trimester up to the day of delivery on obstetric complications and infants. All data were collected retrospectively. Results: Ninety-nine pregnant women had mental disorders and 62 took psychotropic drugs. Among multiple factors, pregnant women with mental disorders were associated with significantly higher rates of smoking and gestational diabetes mellitus (GDM) and significantly lower child abnormalities. The cause or effect was difficult to determine; however, the use of antipsychotics or antidepressants was also significantly associated with GDM, while psychotropic use was not related to any of the other factors investigated in this study. Conclusions: Attention to GDM might be important in the management of pregnant women with mental disorders.
RESUMO
Background: Several hypotheses regarding the pathomechanisms of schizophrenia have been proposed. If schizophrenia is a unitary disease, then these pathological processes must be linked; however, if such links do not exist, schizophrenia may best be considered a group of disorders. Only a few studies have examined the relationships among these pathomechanisms. Herein, we examined the relationships among deficient myelination, NMDA receptor hypofunction, and metabolic dysregulation by measuring various plasma markers and examining their correlations. Methods: Plasma samples were collected from 90 patients with schizophrenia and 68 healthy controls. Concentrations of nardilysin (N-arginine dibasic convertase, NRDC), a positive regulator of myelination, the NMDA receptor co-agonist d-serine and glycine, various additional amino acids related to NMDA receptor transmission (glutamate, glutamine, and l-serine), and homocysteine (Hcy), were measured. Concentrations were compared using independent samples t-test or logistic regression, and associations were evaluated using Pearson's correlation coefficients. Results: Plasma glycine (t = 2.05, p = 0.042), l-serine (t = 2.25, p = 0.027), and homocysteine (t = 3.71, p < 0.001) concentrations were significantly higher in patients with schizophrenia compared to those in healthy controls. Logistic regression models using age, sex, smoking status, glutamine, glutamate, glycine, l-serine, d-serine, homocysteine, and NRDC as independent variables revealed significantly lower plasma d-serine (p = 0.024) and NRDC (p = 0.028), but significantly higher l-serine (p = 0.024) and homocysteine (p = 0.001) in patients with schizophrenia. Several unique correlations were found between NMDA receptor-related amino acids and NRDC in patients with schizophrenia compared to those in healthy controls, while no correlations were found between plasma homocysteine and other markers. No associations were found between plasma marker concentrations and disease status or cognitive function in patients with schizophrenia, except for a significant correlation between plasma glycine and full intelligence quotient. Conclusion: Reduced myelination and NMDA receptor hypofunction may be related to pathological mechanisms in schizophrenia, while homocysteine dysregulation appears to be an independent pathological process. These results suggest that schizophrenia may be a group of disorders with unique or partially overlapping etiologies.
RESUMO
AIM: To investigate the achievement of individualized target HbA1c based on the Japanese guideline after geriatric assessment with the Dementia Assessment Sheet for Community-based Integrated Care System 8-items (DASC-8) and to evaluate patient characteristics acting as barriers to achieving the target HbA1c in elderly outpatients with diabetes. METHODS: This cross-sectional study enrolled 303 Japanese outpatients aged ≥65 years with diabetes. Their health status was measured using the DASC-8. The target HbA1c was optimized for each patient by the guideline based on the DASC-8 score and use of drugs potentially associated with severe hypoglycemia. Patient characteristics related to the agreement between measured HbA1c and target HbA1c were extracted by multivariate logistic regression analysis. RESULTS: The mean age was 73.0 years and the mean body mass index (BMI) was 24.2 kg/m2 . The agreement between measured HbA1c and target HbA1c was 43.9% (95% confidence interval: 38.4%-50.0%). In multivariate logistic regression analysis, the agreement in patients with drugs potentially associated with severe hypoglycemia was significantly lower than in those without these drugs (37.8% vs. 60.5%, P = 0.0004). In patients with these drugs, higher BMI (P = 0.0271) and higher fasting plasma glucose (P = 0.0034) were independent related factors for measured HbA1c being higher than target HbA1c. Vulnerable elderly patients (P = 0.0116) and not taking sodium glucose co-transporter-2 (SGLT2) inhibitor (P = 0.0186) were independent related factors for inappropriately lower HbA1c. CONCLUSIONS: The agreement between measured HbA1c and target HbA1c was low in elderly patients with diabetes. Geriatr Gerontol Int 2022; 22: 560-567.

Objective: Medical science students, especially nursing students, are more likely to experience academic stress; therefore, resilience helps them focus on their lessons attentively. However, the results of a few existing studies regarding how resilience impacts the academic performance of medical science students are incongruent. This study aimed to investigate whether resilience impacts the academic performance of Japanese nursing students. Methods: We conducted a cross-sectional, self-administered questionnaire survey from September to November 2020. A total of 229 undergraduate nursing students participated in this study; here, resilience was measured using the Bidimensional Resilience Scale, which includes innate factors (optimism, control, sociability, and vitality) and acquired factors (problem-solving, self-understanding, and understanding others). Academic performance was measured using the functional grade point average (f-GPA). Covariates were demographics, pre-entry academic performance levels, medical history, time spent walking, psychological distress, subjective economic status, and part-time jobs. Multivariate regression analyses were performed. Results: Among the 229 participants, the f-GPA mean (standard deviation) was 2.93 (0.46). Only vitality was significantly associated with a higher f-GPA after multiple imputations (ß = 0.06; 95% confidence interval = 0.03-0.09; P<0.01). The Poisson regression analysis of 212 participants with all data indicated that vitality was associated with the fourth quartile f-GPA (prevalence ratio, 1.05; 95% confidence interval, 1.03-1.08; P<0.01). Conclusion: There was a significant association between the vitality of resilience components and academic performance among Japanese nursing students. This study suggests that an approach that develops resilience is necessary for the academic success of nursing students.
RESUMO
Hydrophilic chlorophyll (Chl)-binding proteins have been isolated from various Brassicaceae plants and are categorized into Class II water-soluble Chl-binding proteins (WSCPs). Although the molecular properties of class II WSCPs including Brassica-type (e.g., cauliflower WSCP, Brussels sprouts WSCP and BnD22, a drought- and salinity-stress-induced 22 kDa protein of rapeseed), a Lepidium-type, and an Arabidopsis-type WSCPs have been well characterized, those of Raphanus-type WSCPs are poorly understood. To gain insight into the molecular diversity of Class II WSCPs, we cloned a novel cDNA encoding a Raphanus sativus var. raphanistroides (Japanese wild radish called 'Hamadaikon') WSCP (RshWSCP). Sequence analysis revealed that the open reading frame of the RshWSCP gene consisted of 666 bp encoding 222 aa residues, including 23 residues of a deduced signal peptide. Functional recombinant RshWSCP was expressed in Escherichia coli as a hexa-histidine fusion protein (RshWSCP-His). Although the RshWSCP-His was expressed as a soluble protein in E. coli, the apo-protein was highly unstable and tended to aggregate during a series of purification steps. When the soluble fraction of RshWSCP-His-expressing E. coli was mixed immediately with homogenate of spinach leaves containing thylakoid, RshWSCP-His was able to remove Chl molecules from the thylakoid and formed a stable Chl-WSCP complex with high hydrophilicity. UV-visible absorption spectra of the reconstituted RshWSCP-His revealed that RshWSCP-His is one of the Class IIA WSCP with the highest Chl a/b ratio analyzed thus far. A semi-quantitative reverse transcription-polymerase chain reaction analysis revealed that RshWSCP was transcribed in buds and flowers but not in roots, stems and various leaves.
