Objectives: Traditional variable-oriented research has shown that employee perceptions of job insecurity (JI) are associated with negative consequences, including more work-home interference, poorer health, and impaired well-being. Besides the negative consequences of high JI, particular combinations of JI perceptions may also be associated with different consequences. Taking a person-oriented approach, this study aimed to investigate (1) whether it is possible to distinguish different combinations of JI perceptions among working women and men and (2) whether such JI profiles involve different experiences of work-home interference, health, and well-being. Methods: Self-reports in questionnaires of JI, including both quantitative and qualitative threats of perceived job loss, work-home interference (WHI), health, and psychological well-being came from 1169 white-collar workers (52.4% women) in Sweden. Latent profile analysis was performed to identify JI profiles. Subsequent analyses included comparing profiles with respect to WHI, health, and well-being. Results: Four distinct JI profiles were identified: (1) Secure; quality-concerned, (2) Insecure: employment-concerned, (3) Insecure, and (4) Secure. Comparisons of cluster profiles showed significant differences in work-home interference (family-work conflict), self-rated health, and psychological well-being. Conclusions: Findings suggest that the Insecure profile may be most vulnerable to adverse consequences of perceived JI. Taken together, different JI profiles may be associated with differential experiences of work-home interference, health, and psychological well-being among working women and men. Nowstars

Objective Self-harm and attempted suicide are risk factors for suicide in psychiatric hospital in-patients. This study aimed to analyse the circumstances of self-harm and suicide attempts in a Japanese psychiatric hospital so as to improve management and care. Methods Incident reports of self-harm and suicide attempts during a 12.4-year period from November 2000 to March 2013 were reviewed. A descriptive analysis was conducted in terms of age, sex, and diagnosis of patients, as well as level, ward, situations, and causes of incidents. Results During the study period, 90 cases of self-harm and attempted suicide involving 58 patients were reported. The rate of self-harm and suicide attempts was 0.05 per 1000 patient-days. The types of selfharm and suicide attempts included hanging (n = 25), wrist cutting (n = 19), ingestion of foreign objects (n = 17), and others (n = 29). The single case of completed suicide involved hanging, in a patient with schizophrenia. Among 55 patients with relevant data, the most common clinical diagnosis was mood disorder (41.8%), followed by schizophrenia (36.4%). Mood disorder was 3.5 times as prevalent in females as in males (14 vs. 4). Fourteen patients with mood disorder (n = 8) or schizophrenia (n = 6) were repeatedly involved in 46 of 89 cases of self-harm or attempted suicide; 11 were female. One woman with mood disorder attempted suicide 9 times within the same year. The top 3 management and care factors related to self-harm and suicide attempts were failure to adhere to preventive procedures (28%), insufficient therapeutic communication (28%), and difficulty in predicting suicide (20%). Conclusion Self-harm and suicide attempts at this psychiatric hospital occurred at a rate of 0.05 per 1000 patient-days between late 2000 and early 2013. Efforts are needed to increase compliance with suicide prevention procedures and therapeutic communication, so as to improve management and care of psychiatric in-patients and prevent them from committing suicide.

Age-related macular degeneration (AMD) is one of the leading causes of blindness among older adults in developed countries and also in Japan. Previous research suggests that AMD is etiologically a complex disease, caused by multiple genes and environmental factors. Association studies have identified that a complement factor H gene (CFH) variant is a major risk factor for AMD in Caucasians. However, we and two other groups have reported no association between CFH and AMD in the Japanese population. Recent studies have suggested that LOC387715 on chromosome 10q26 may be the second major risk loci for AMD in Caucasians. In this study, we examined the association between LOC387715 and AMD in Japanese, and our results show that polymorphism of the LOC387715 gene is associated with AMD in Japanese as well as in Caucasians. Our data show a disease odds ratio of 6.20 (95% CI: 2.87-13.40) conferred by homozygosity for risk alleles at LOC387715 compared with the non-risk genotype. A polymorphism of LOC387715 gene is associated with AMD in the Japanese population.

Clostridium difficile infection control strategies require an understanding of its epidemiology. In this study, we analysed the toxin genotypes of 130 non-duplicate clinical isolates of C. difficile from a university hospital in Tokyo, Japan. Multilocus sequence typing (MLST) and eBURST analysis were performed for these isolates and nine strains previously analysed by polymerase chain reaction (PCR) ribotyping. Minimum inhibitory concentrations (MICs) were determined for six antibiotics, and the bacterial resistance mechanisms were investigated. Ninety-five toxigenic strains (73%), including seven tcdA-negative, tcdB-positive and cdtA/cdtB-negative strains (A(-)B(+)CDT(-)) and three A(+)B(+)CDT(+) strains, and 35 (27%) non-toxigenic strains, were classified into 23 and 12 sequence types, respectively. Of these, sequence type (ST)17 (21.8%) was the most predominant. MLST and eBURST analysis showed that 139 strains belonged to seven groups and singletons, and most A(+)B(+)CDT(-) strains (98%, 89/91) were classified into group 1. All isolates were susceptible to metronidazole, vancomycin and meropenem; the ceftriaxone, clindamycin and ciprofloxacin resistance rates were 49, 59 and 99%, respectively. Resistance rates to ceftriaxone and clindamycin were higher in toxigenic strains than in non-toxigenic strains (P 0.001). All ST17 and ST81 strains were resistant to these antibiotics. The clindamycin- and fluoroquinolone-resistant strains carried erm(B) and mutations in GyrA and/or GyrB, respectively. To our knowledge, this is the first MLST-based study of the molecular epidemiology of toxigenic and non-toxigenic strains in Japan, providing evidence that non-toxigenic and toxigenic strains exhibit high genetic diversity and that toxigenic strains are more likely than non-toxigenic strains to exhibit multidrug resistance.

Purpose To describe a case of persistent hypotony after an otherwise successful vitreous surgery for epiretinal membrane, in which ciliochoroidal detachment was detected by ultrasound biomicroscopy but not by ophthalmoscopy. Method We used ultrasound biomicroscopy to determine the cause of persistent postoperative hypotony. Results Ultrasound biomicroscopy clearly disclosed ciliochoroidal detachment. In an attempt to resolve ciliochoroidal detachment, we performed vitrectomy and fluid-gas exchange combined with diathermy around the sites of sclerotomy. Postoperatively, the regression of ciliochoroidal detachment was confirmed by ultrasound biomicroscopy. Conclusions Using ultrasound biomicroscopy, we were able to visualize ciliochoroidal detachment and its regression clearly, which we had not observed during ophthalmoscopy.

It has been reported that the general public has the impression that many of the homeless people have alcoholic problems, and that these problems make their life problems worse. While there has been some research on this subject, most of them focus on the people who use public or private services. So, this study was conducted to investigate the alcoholic problems focused on the homeless people who were around Shibuya station. An investigation covering the questions about their job, company, sleeping style, amount of alcohol taken per day, CAGE and blood examination was compiled using questionnaires. The results were compared with people who are not homeless people and among homeless people. There were forty-nine homeless people who responded to the questionnaire and 34 homeless people who responded to the blood examination. The mean age of the homeless people was 53.1 years and no significant difference was seen between the homeless and the control. About 46% of the homeless reported that they do not drink. Sixteen per cent of the homeless respondents answered positively to the CAGE, No difference was found in having past history of liver dysfunction and in blood examination between them. There was a tendency that the amount of alcohol increases when the homeless have company. The level of gamma GTP increased significantly according to the amount of alcohol (p0.05). This study can be valued because of the attempt to focus not on the homeless who use services but on the homeless who stayed in the city. But the number of the targeted homeless people was small and there was selection bias that is not easy to be excluded in this type of research. Further studies on the impact of alcohol etc. should be developed to improve their lives.

The oral absorption of FK506 in solid dispersion formulation was studied in rats. The obtained area under the concentration versus time curve (AUC) increased in a nonlinear fashion with a small dose-dependent increase in the peak blood concentrations (Cmax). The peak concentration time (Tmax) was observed within 30 min after administration in all dosing groups (1-10 mg/kg) with or without feeding, whereas the oral absorption of FK506 was reduced to about 50% by gavage at a dose of 1 mg/kg. Participation of first-pass elimination was suggested by comparing the blood levels after infusion via the portal vein with those after infusion via the femoral vein. Further, in an in vitro stability study and an in situ loop absorption study, FK506 was fairly stable in the gastrointestinal juice and was absorbed predominantly from the upper part of the small intestine.

Diffuse panbronchiolitis (DPB) is a disease with chronic inflammation exclusively located in the region of respiratory bronchioles. The pathologic features of the disease are characterized by thickening of the wall of the respiratory bronchiole with infiltration of lymphocytes, plasma cells and histiocytes, and extension of the inflammatory changes toward peribronchiolar tissues. In the advanced stage, secondary ectasia of proximal bronchioli may occur. These changes appear as diffusely disseminated small nodular shadows throughout both lungs on the chest roentgenogram. Obstructive respiratory functional impairment, occasional symptoms of wheezing, and also cough and sputum resemble the feature of emphysema, bronchial asthma, or chronic bronchitis, respectively. In the advanced stage, large amounts of purulent sputum and dilatation of proximal terminal conducting bronchioli resemble bronchiectasis. However, diffuse panbronchiolitis belongs to a distinctly different category from these diseases, and should be distinguished from them, because it may often show rapid progression with fatal outcome. The disease is dominant in males and the onset is unrelated to age. More than 1,000 cases of probable diffuse panbronchiolitis and 82 histologically-confirmed cases have been collected in Japan.

Secretion of luteinizing hormone (LH) and its beta-subunit (LH-beta) by luteinizing hormone-releasing hormone (LH-RH) were studied in perifused rat anterior pituitary cells. LH release was dose related between 10(-10) and 10(-6)M LH-RH. Every 5-minute pulse of 10(-8)M LH-RH induced almost similar response to the initial LH release; neither the self-priming effect nor desensitization were significant. Continuous administration of 10(-8)M LH-RH caused an initial LH release, followed by distinct desensitization, which could not be overcome by subsequent pulses of 10(-8)M LH-RH. The results were quite similar in LH-beta release. The perifusion study is shown to be useful in analyzing the characteristics of LH and LH-beta release, and the present results suggest that LH-RH receptor-mediated regulation may be also involved in LH-beta release.
