Objective To investigate the course and influencing factors of postpartum depression in women during the child rearing period. Methods Data were collected during 0-year-old baby check-ups and a follow-up investigation. 262 participants were included in the analysis. Both surveys employed the Zung Self-Rating Depression Scale (ZSDS). The first also comprised the State Trait Anxiety Inventory, Parental Bonding Instrument (PBI), and Borderline Scale Index, enabling sub-division of participating subjects into healthy/pathological groups. ZSDS group and survey scores were compared using the t-test. Results The average ages of the children and the ZSDS scores in both surveys were 7.0±3.2 and 21.8±2.4 months, 40.6±7.9 and 40.1±8.7, respectively, with no significant differences among depression scores. When subjects were divided according to individual scale scores, and survey scores compared, depression significantly improved in the high trait/state anxiety group, high PBI maternal care score group, nonborderline personality (BP) trait group, and breast feeding group, whereas depression was significantly exacerbated in the low PBI maternal care score group. Discussion Postpartum depression characterized by strong anxiety and a depressive state in mothers with favorable psychological backgrounds showed gradual improvement. We noted an exacerbation of depression during the separation period in mothers who had received poor maternal care. We assume that the feeling of abandonment induced by individuation of their children is a major factor. Limitations There is concern that some depressive women may have dropped out due to a performance bias. Conclusions Sharing our findings about exacerbation/improvement of depression among medical staff may be beneficial for postpartum mothers. © 2013 Elsevier B.V.

Purpose: A multidimensional intervention integrating alexithymia, negative affect, and type of coping strategy is needed for the effective treatment of somatoform disorder; however, few studies have applied this approach to the three different dimensions of alexithymia in patients with somatoform disorder. The purpose of this study was to determine the relationship between type of coping strategy and three different dimensions of alexithymia expressed in patients. Patients and methods: A total of 196 patients with somatoform disorder completed the 20-item Toronto Alexithymia Scale, the Zung Self-Rating Depression Scale, the Spielberger State-Trait Anxiety Inventory, the Somatosensory Amplification Scale, and the Lazarus Stress Coping Inventory. The relationships between alexithymia (Toronto Alexithymia Scale - 20 score and subscales), demographic variables, and psychological inventory scores were analyzed using Pearson's correlation coefficients and stepwise multiple regression analysis. Results: The mean Toronto Alexithymia Scale - 20 total score (56.1±10.57) was positively correlated with the number of physical symptoms as well as with psychopathology scores (Self-Rating Depression Scale, State-Trait Anxiety Inventory trait, state, and Somatosensory Amplification Scale), but negatively correlated with planful problem solving, confrontive coping, seeking social support, and positive reappraisal coping scores. With respect to coping strategy, multiple regression analyses revealed that "difficulty in identifying feelings" was positively associated with an escape-avoidance strategy, "difficulty in describing feelings" was negatively associated with a seeking social support strategy, and "externally oriented thinking" was negatively associated with a confrontive coping strategy. Conclusion: Alexithymia was strongly associated with the number of somatic symptoms and negative affect. Patients with high "difficulty in describing feelings" tend to rely less on seeking social support, and patients with high "externally oriented thinking" tend to rely less on confrontive coping strategies. The coping skills intervention implemented should differ across individuals and should be based on the alexithymia dimension of each patient. © 2014 Tominaga et al.

For reducing the hemodialysis time of kidney disease patients, we are attempting to monitor hemodialysis quality in a real time based on dielectric constants of blood. Using a network analyzer with an open-ended coaxial-type dielectric probe, we measured complex relative permittivities ranging from 200 MHz to 6 GHz for blood of eighteen kidney disease patients before and after hemodialysis, and then derived from them admittance consisting of conductance G [S/m] and susceptance B [S/m] in order to make statistical correlation analyses between the G-B plots and blood biochemical components. As a result, we found that significant correlations are observed between the parameters of the linear approximations to the G-B plots at frequencies from 4 GHz to 6 GHz and blood urea nitrogen or creatinine before and after the hemodialysis. This finding suggests a possibility of real-time monitoring of the hemodialysis quality. © 2014 The Institute of Electrical Engineers of Japan.

For evaluating the quality of hemodialysis from the limited volume of human blood using a commercially available open-ended coaxial probe, we previously measured for 10 normal healthy subjects and 9 patients who require hemodialysis the dielectric properties of 2.5 ml whole blood with a temperature of 25 degrees centigrade in a syringe with a diameter of 20 mm and a depth of 8 mm. In this study, we measured the complex relative permittivity of water and human blood when changing temperature from 25 to 37 degrees centigrade in order to examine the correlation between them, and calculated their Pearson product-moment correlation coefficients for ε r' and ε r'' along with significant probability P based on a t-test. It should be noted that P is a reference probability to determine whether or not a null hypothesis can be rejected, and that the P value of 0.05 is commonly used as a significance level for a statistical test. As a result, it was found for the complex relative permittivity of water that there is approximately good agreement between the measured results and calculated ones from the Kaatze formula expressed as a function of temperature, and that strong correlations with P < 0.05 are also confirmed between the complex relative permittivity and temperature. For the human blood, on the other hand, we found that a strong correlation with P < 0.05 is observed between ε r'' and temperature, while there is not always significant correlation with P > 0.05 between ε r' and temperature. © 2013 The Institute of Electrical Engineers of Japan.

Before evaluating the quality of hemodialysis from the limited volume of human blood using a commercially available open-ended coaxial probe, we previously measured the complex relative permittivity of pure water from 200 MHz to 6 GHz with respect to its measured liquid volume, and revealed that 1.9 ml water in a beaker with a diameter of 24 mm and a depth of 2 mm gives a variation within ±0.5 % for the real part and ±7 % for the imaginary part. Based on the above finding, we measured the dielectric properties of 2.5 ml whole blood at 25°C for 10 normal healthy subjects and 9 hemodialysis patients. The measured results on healthy subjects show good agreement with the data reported by Gabriel for human blood at 37°C, while they provide different dispersion characteristics of straight lines for their Cole-Cole plots. The measured results on the patients give further different dispersion characteristics in comparison with the healthy subjects. In order to investigate the above differences statistically, the student t-test was conducted to reveal that permittivity at infinite frequency for the Cole-Cole plots is significantly different with a level of 1 % among its averaged values for normal healthy subjects and patients before dialysis. © 2011 The Institute of Electrical Engineers of Japan.
