1) All students but 1 correctly typed the ABO blood groups, but only 33.2% of students and 63.9% of physicians properly performed cross-matching.
2) Most failures in cross-matching were due to the inability to detect allogeneic antibodies, but 5.2% of students and 2.9% of physicians failed to detect ABO mismatching.
3) Although laboratory practice is suggested to help students to solidify knowledge and comprehend principles, achieving an official goal of residency - gaining competence in performing and interpreting cross-matching independently - appeared difficult.

OBJECTIVESThe purpose of this study was to assess the validity of the candidate indicators secretory immunoglobulin A (s-IgA) and sense of coherence (SOC) as predictors of threatened premature birth.
METHODSThis was a panel study conducted on women in their first and latter half of pregnancy during survey period. The survey period was from December 2005 to June 2006 and from December 2007 to June 2008. The women enrolled in the study were asked to complete the survey questionnaire and provide blood samples for the determinations of physiological indicators. The questionnaire consisted of questions related to the stress perception scale (SPS), SOC score as an indicator of modifiers of stress, demographic data, complications in a previous pregnancy, and the course of the current pregnancy. We used s-IgA and high-sensitivity C-reactive protein as a physiological stress indicator and a marker of infection, respectively. Seventy-two eligible subjects were included in the analysis.
RESULTSTwenty-eight (38.9%) subjects had undergone treatment for threatened premature birth, and 44 (61.1%) subjects had not. In the logistic analysis, we set the course of pregnancy as a dependent variable, and age, birth history, smoking habits, a history of miscarriage, premature birth or threatened premature birth, SPS, SOC, and s-IgA in the first half of pregnancy as independent variables. We found that low serum s-IgA levels and low SOC scores in the first half of pregnancy were associated with threatened premature birth.
CONCLUSIONSOur results suggest that low serum s-IgA level and SOC score at an early gestational stage are significant indicators for a threatened premature birth.

OBJECTIVEThe aim of our study was to explore the relationship between a medium-scale earthquake and maternal depression and child-rearing in a depopulated community in the Noto Peninsula of Japan.
METHODSThree months after a major earthquake, self-rating questionnaires were distributed to women who were pregnant at the time of the earthquake or who became pregnant immediately thereafter, and who were receiving care at any of four major hospitals in the most devastated area. A total of 155 women who had given birth returned the completed questionnaire for analysis. Maternal postnatal depression among the participants was assessed using the Edinburgh Postnatal Depression Scale (EPDS).
RESULTSThe EPDS score was significantly associated with decreased "satisfaction with delivery" (beta = -0.28, p = 0.01), increased artificial "lactation" (beta = 0.31, p = 0.002), and increased "trouble with infant care" (beta = 0.47, p < 0.001) in multivariate analysis. It was also significantly associated with increased "anxiety about earthquakes" (beta = 0.30, p = 0.001), and "anxiety about earthquakes" was significantly associated with increased "fear of the earthquake" (beta = 0.20, p = 0.04).
CONCLUSIONSEarthquake-related factors such as "anxiety about earthquakes" and "fear of the earthquake" did not have a direct effect on child-rearing factors; however, they did have a significant relationship with increased EPDS. Based on these results, we conclude that screening strategies for maternal depression in peri- and postnatal women under emergency circumstances are necessary.

OBJECTIVEIn this study, we evaluated postpartum stress using a postpartum depression scale and by measuring the level of a stress-related substance, to clarify the relationship between the stresscoping capabilities of women in the final stage of pregnancy and their postpartum stress reactions.
METHODSBetween April 2004 and October 2004, 54 women participated in a question naire survey and the measurement of their secretory immunoglobulin A (s-IgA) level as a stress-related substance two times in the final stage of their pregnancy (prepartum) and in their early puerperium (postpartum) was carried out. The questionnaire used in the prepartum stage included the following parameters: "basic features", "Sense of Coherence (SOC)" and "Japanese version of the self-assessment depression scale" of Zung. The questionnaire employed in the postpartum stage included the following parameters: "course of delivery", "Self-evaluation of delivery experience", and "Postpartum depression scale".
RESULTSThe depression score was higher and the s-IgA level was lower in the low-SOC score group than in the high-SOC score group, indicating that stress reactions were more intense in the low-SOC score group.
CONCLUSIONIt was revealed that stress reactions were more intense for women with a low SOC score. Moreover, the finding of a relationship between the low SOC score in the prepartum stage and depressive tendency suggests that women who are likely to develop depressive tendency can be predicted in the prepartum stage, and the significance of measuring SOC in the prepartum stage is thus suggested.

OBJECTIVESThe demand for mobile bathing service (MBS) is increasing in the Japanese society. Therefore, we assessed the risk of MBS-associated infection in MBS clients and their caregivers by examining the bacterial colonization of MBS equipment and utensils.
METHODSBacterial isolates collected by the stamp agar culture method were examined by disk diffusion assay for their susceptibility to the following drugs: imipenem, ciprofloxacin, amikacin, azutreonam, ceftazidim, meropenem, piperacillin, tobramycin, ofloxacin and cefoperazone. Furthermore, these isolates were subtyped bySpeI-pulsed field gel electrophoresis (SpeI-PFGE).
RESULTSFifty-fourP. aeruginosa isolates were recovered from different sampling sites, and of these, 26 (47.3%) were isolated from pillows. Eighteen isolates (33.3%) were imipenem (IPM) resistant. The minimum inhibitory concentrations (MICs) of 17 isolates were between 16 and 32 μg/ml, and the MIC of one isolate was greater than 32 μg/ml. TheSpeI-PFGE typing of IPM-resistant isolates revealed that 13 of the 18 isolates were closely related (F=1.0-0.87).
CONCLUSIONOur findings suggest that MBS equipment and utensils, particularly pillows, are the primary sources of bacterial contamination and transmission and that there is a risk of MBS-mediated infection among MBS clients and their caregivers.

BACKGROUND:
It has been pointed out that prolonged television (TV) viewing is one of the sedentary behaviors that is harmful to health; however, the association between socioeconomic status (SES) and prolonged TV viewing time has not been sufficiently investigated in Japan.
METHODS:
The study population are the participants of NIPPON DATA2010, which is a prospective cohort study of the National Health and Nutrition Survey 2010 in Japan. They were residents in 300 randomly selected areas across Japan. This study included 2752 adults. SES was classified according to the employment status, educational attainment, living status, and equivalent household expenditure (EHE). Prolonged TV viewing time was defined as more than or equal to 4 h of TV viewing per day. Multivariable logistic regression analyses were conducted to examine the association of SES with prolonged TV viewing time.
RESULTS:
The mean TV viewing time was 2.92 h in all participants. Of 2752 participants, 809 (29.4%) prolonged TV viewing, and the mean TV viewing time of them was 5.61 h. The mean TV viewing time in participants without prolonged TV viewing time was 1.81 h. The mean TV viewing time was prolonged as age classes increased and significantly longer in aged ≥60 years. Prolonged TV viewing time was associated with not working for all age classes and sexes. Only among women, education attainment and living status were also associated with prolonged TV viewing time. For education attainment, the lower the received years of education, the higher odds ratios (OR) of prolonged TV viewing time. For living status, in women aged <60 years, living with others had a significantly higher OR compared to living with spouse. On the other hand, in women aged ≥60 years, living alone had a significantly higher OR. EHE did not have any significant associations with prolonged TV viewing time.
CONCLUSIONS
In a general Japanese population, it should be noted that the association between SES and prolonged TV viewing time differed by age and sex. Particularly, it must draw attention to the prolonged TV viewing in elderly. The intervention in order to shorten TV viewing time needs to consider these attributes.

BACKGROUND:
The gender-specific characteristics of individuals at an increased risk of developing depression currently remain unclear despite a higher prevalence of depression in women than in men. This study clarified socioeconomic and lifestyle factors associated with an increased risk of subclinical depression in general Japanese men and women.
METHODS:
Study participants were residents not receiving psychiatric treatments in 300 sites throughout Japan in 2010 (1152 men, 1529 women). Multivariable-adjusted odds ratios (OR) and 95% confidence intervals (95%CIs) for socioeconomic factors and lifestyle factors were calculated using a logistic regression analysis.
RESULTS:
Risk of depressive tendencies was significantly higher in men who were single and living alone (OR, 3.27; 95% CI, 1.56-6.88) than those married. The risk was significantly lower in women who were not working and aged ≥ 60 years (OR, 0.39; 95% CI, 0.22-0.68) and higher in men who were not working and aged < 60 years (OR, 3.57; 95%CI, 1.31-9.72) compared with those who were working. Current smoking was also associated with a significantly increased risk of depressive tendencies in women (OR, 2.96; 95% CI, 1.68-5.22) but not in men.
CONCLUSIONS
Socioeconomic and lifestyle factors were associated with an increased risk of depressive tendencies in general Japanese. Related factors were different by sex.
