Abstract
Helicobacter pylori (H. pylori) is a predominant pathogen that causes not only gastroduodenal diseases but also extra-alimentary tract diseases. In this study, we demonstrated that H. pylori infection promoted atherogenesis in heterozygous apoe(+/ --) ldlr(+/--) mice. The male mice were fed with high fat diet from the age of 6 weeks. At the age of 16 weeks, development of atherosclerotic lesions was observed in the H. pylori-infected mice, and it seemed to be associated with an elevation of Th1-immune response against H. pylori origin-heat shock protein 60 (Hp-HSP60) and an increment of transendothelial migration of T cells. Subcutaneous immunisation with Hp-HSP60 or H. pylori eradication with antibiotics significantly reduced the progression of atherosclerosis, accompanied by a decline of Th1 differentiation and reduction of their chemotaxis beyond the endothelium. Thus, oral infection with H. pylori accelerates atherosclerosis in mice and the active immunisation with Hp-HSP60 or the eradication of H. pylori with antibiotics can moderate/prevent cellular immunity, resulting in a reduction of atherosclerosis.

Abstract
Purpose The aim of this study was to clarify the level of emotional distress experienced by bereaved family members and the perceived necessity for improvement in the care for imminently dying patients and to explore possible causes of distress and alleviating measures. Methods A cross-sectional nationwide survey was performed in 2007 of bereaved families of cancer patients at 95 palliative care units across Japan. Results Questionnaires were sent to 670 families, and 76% responded. Families reported their experiences as very distressing in 45% of cases. Regarding care, 1.2% of respondents believed that a lot of improvement was needed, compared with 58% who believed no improvement was needed. Determinants of high-level distress were a younger patient age, being a spouse, and overhearing conversations between the medical staff outside the room at the time of the patient's death; those reporting high-level necessity of improvement were less likely to have encountered attempts to ensure the patient's comfort, received less family coaching on how to care for the patient, and felt that insufficient time was allowed for the family to grieve after the patient's death. Conclusion A considerable number of families experienced severe emotional distress when their family member died. Thus, we propose that a desirable care concept for imminently dying cancer patients should include relief of patient suffering, family advisement on how to care for the patient, allowance of enough time for the family to grieve, and ensuring that family members cannot overhear medical staff conversations at the time of the patient's death.

Abstract
INTRODUCTION Porphyromonas gingivalis is implicated as a major pathogen in the development and progression of chronic periodontitis. P. gingivalis must possess the ability to tolerate stress signals outside the cytoplasmic membrane by transcriptional activation of genes encoding proteins involved in defense or repair processes. Some bacteria utilize a distinct subfamily of sigma factors to regulate extracytoplasmic function (hence termed the ECF subfamily). METHODS To elucidate their role in P. gingivalis, a chromosomal mutant carrying a disruption of an ECF sigma factor PG1318-encoding gene was constructed. Hemagglutination and proteolytic activities were measured in the PG1318-defective mutant. Reverse transcription-polymerase chain reaction (RT-PCR) analysis and southern blot analysis were used to assess transcription of kgp in the PG1318-defective mutant. Frequency of spontaneous mutation that conferred resistance to l-trifluoromethionine was measured in the PG1318-defective mutant. RESULTS The PG1318-defective mutant formed non-pigmented colonies on blood agar plates at a relatively high frequency. Arginine-specific and lysine-specific proteinase activities of the non-pigmented variants were remarkably decreased compared with those of the parent strain and the pigmented variants. RT-PCR analysis showed that kgp was not transcribed in some non-pigmented variants and southern blot analysis revealed that there was a deletion in their kgp region. Frequency of mutation conferring resistance to l-trifluoromethionine was significantly higher in the PG1318-defective mutant than in the wild-type. CONCLUSION These results suggest that PG1318 plays a role in the regulation of mutation frequency in the bacterium.

Abstract
The aim of this study was to explore the most suitable religious care for Japanese terminally ill patients with cancer based on the opinions of bereaved family members. A multicenter questionnaire survey on palliative care service was sent to 592 bereaved family members of patients with cancer who were admitted to palliative care units in Japan, and 430 responded by mail. In the section of the questionnaire about religious care, 382 responses were used for quantitative analysis, and 71 responses about religious care for qualitative analysis. In the current study, the 71 responses were grouped into families with and without a religion and were analyzed qualitatively. Families with a religion (N = 28) chose answers such as ‘‘Instrumental care’’ such as music or a religious event, ‘‘Freedom of choice of kinds for religious care,’’ ‘‘Staff involvement of religious care,’’ ‘‘Meeting with a pastoral care workers,’’ and ‘‘Burden of offering a different kind of personal religion.’’ In contrast, families without a religion (N = 44) chose answers such as ‘‘Instrumental care,’’ ‘‘Freedom of choice whether patients receive religious care or not,’’ ‘‘Spiritual care,’’ ‘‘Not being able to accept religious care,’’ and ‘‘Burden of thinking about a religion and nuisance.’’ These findings suggest that Japanese bereaved families with a religion generally regard religious care positively and prefer care through their own religion, whereas some families without a religion require religious care but some do not prefer it.

Abstract
A seroepidemiological survey of antibodies to human T-lymphotropic retrovirus type-1 (HTLV-1) was carried out among 413 residents of Chitwan, Dhapakhel and Katmandu in Nepal. Donor screening was first carried out by the gelatin particle agglutination (PA) tests and positive sera were retested by an improved PA test, indirect immunofluorescence (IF) and Western blotting (WB). Nine sera showed positive reaction in the first PA screening. Among these positive sera, 1 serum was positive in the improved PA test and the IF test but negative in the WB test. This study suggests that the prevalence of HTLV-1 in Nepalese people is negligible.

Abstract
OBJECTIVES A psychometric scale for assessing cancer-related worry among cancer patients, called the Brief Cancer-Related Worry Inventory (BCWI), was developed. METHODS A cross-sectional questionnaire survey for item development was conducted of 112 Japanese patients diagnosed with breast cancer, and test-retest validation analysis was conducted using the data from another prospective study of 20 lung cancer patients. The questionnaire contained 15 newly developed items for cancer-related worry, the Hospital Anxiety and Depression Scale, The Impact of Event Scale Revised, and the Medical Outcomes Study Short Form-8. RESULTS Exploratory factor analysis of the 15 items yielded a 3-factor structure including (1) future prospects, (2) physical and symptomatic problems and (3) social and interpersonal problems. A second-order confirmatory factor analysis identified a second-order factor called cancer-related worry and confirmed the factor structure with an acceptable fit (chi-square (df=87)=160.16, P=0.001; GFI=0.83; CFI=0.92; RMSEA=0.09). The internal consistency and test-retest reliability were confirmed with the lung cancer sample. Multidimensional scaling found that cancer-related worry is separate from anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms. CONCLUSION Our study succeeded in developing and confirming the validity and reliability of a BCWI. The study also confirmed the discriminable aspects of cancer-related worry from anxiety, depression, and PTSD symptoms.

Abstract
BACKGROUND/AIMS Diffuse type advanced gastric cancer (D-AGC) is highly malignant disorder with dismal prognosis, however the causative attribution explaining such malignancy remains fully unexplained as compared to intestinal type AGC (I-AGC). METHODOLOGY We examined the archive of 232 AGC with cytology test (CY) but no distant metastasis, who underwent gastrectomy in Kitasato University Hospital in order to reveal the prognostic significance of D-AGC in a multivariate approach. RESULTS D-AGC occupied 68% (157/232) among AGC, and showed poorer prognosis than I-AGC (p = 0.024). Multivariate prognostic analysis revealed that independent prognostic factors for AGC are CY (p < 0.0001), pN (p = 0.0068), pT (p = 0.015), and age (p = 0.012), and that histology was eliminated, suggesting that histology itself does not represent high malignancy within the identical stage. D-AGC was significantly associated with younger age (p = 0.018), female preponderance (p = 0.006), advanced pT (p = 0.0002), advanced pN (p = 0.016), and positive CY factors (p = 0.032), among which negative prognostic factors were pT, pN, and CY factors. Multivariate logistic regression analysis elucidated that both pT (serosal exposure, p = 0.013) and CY (p = 0.034) factors were finally remnant independent predictors for D-AGC among the 3 univariate negative prognostic factors, but that pN was not. Intriguingly, age could be an independent prognostic factor only in D-AGC. CONCLUSION Our research revealed for the first time that more dismal prognosis of D-AGC than I-AGC could be explained by propensity of deeper invasion and emerging peritoneal cancer cell, and histology itself did not have a prognostic value, hence indicating that present staging system works properly even in D-AGC as well as I-AGC. We must identify its molecular mechanism of both invasion and emerging peritoneal disease of D-AGC in order to improve the prognosis.

Abstract
Aims The purpose of this study was to examine HRQOL depending on whether the participants have family members with disabilities or not. In addition, we examined the relationship between HRQOL and social networks among family caregivers in Japan. Methods The study has a cross-sectional design. Survey forms were distributed to 9205 people aged 30 and older who visited a dispensing pharmacy within fifteen areas of Japan. We collected data on gender, age, job status, and care giving status for persons with disabilities. Moreover, we assessed support size, social support, and HRQOL. Out of the 2029 questionnaires returned, 1763 (male: 663, female: 1100, mean age = 63.06 ± 13.34) were valid for statistical analyses (the available response rate was 19.15%). Results A significant difference in HRQOL was identified between family caregivers and non-family caregivers. Further, in males (N = 101), the results confirmed that only social support predicted the PCS and MCS scores, while other variables did not predict either score. On the other hand, in females (N = 144), it was found from the second step of hierarchical multiple regression analysis that only age explained the PCS score, while job status and support size explained the MCS score. Conclusion It is reasonable to conclude that the HRQOL of family caregivers was lower than that of non-family caregivers, and that the HRQOL of family caregivers was estimated by their social networks.

Abstract
By use of monoclonal antibody against a Marek's disease virus (MDV) serotype 1-specific phosphorylated protein, MDV antigen-positive cells were demonstrated in tumour lesions of various visceral organs of chickens with Marek's disease. However, these tumour lesions did not appear to have the MDV glycoproteins gA and gB, which are considered to be late gene products of the virus genome gA and gB as well as the phosphorylated protein were detected in the feather follicle epithelium, which is a permissive site for MDV replication.

Abstract
High incidences of aspergillosis (12.9%) and candidiasis (15.4%) were encountered in 241 psittacines and passeriformes which died within 2 weeks of quarantine after being imported into Japan. Respiratory aspergillosis was diagnosed in 31 birds which involved mainly the nasal cavity (17 birds), lung (14 birds) and air sac (13 birds). Thirty-seven birds had candidial lesions in various organs, especially in the nasal cavity (22 birds), crop (17 birds), oesophagus (12 birds), proventriculus (6 birds) and gizzard (6 birds). The study provided strong evidence that the nasal cavity was an important entry and multiplication site for the both mycoses in psittacine birds. Aspergillus spp. had an affinity for the respiratory region of the nose, inducing an exudative rhinitis. Two types of tissue reaction, invasive and granulomatous, were found in the lung and air sac, although the former type was predominant. Candida spp. often attacked the vestibular region of the nose. This agent caused a hyperkeratotic change in the nasal cavity and other mucous membranes such as the crop, gizzard and cloaca. Cutaneous aspergillosis and candidiasis with or without poxvirus infection were also observed.

Abstract
Surveying bereaved family members could enhance the quality of end-of-life cancer care in inpatient palliative care units (PCUs). We systematically reviewed nationwide postbereavement studies of PCUs in Japan and attempts to develop measures for evaluating end-of-life care from the perspective of bereaved family members. The Care Evaluation Scale (CES) for evaluating the structures and processes of care, and the Good Death Inventory (GDI) for evaluating the outcomes of care were considered suitable methods. We applied a shortened version of the CES to three nationwide surveys from 2002 to 2007. We developed the CES as an instrument to measure the structures and processes of care and the GDI as an outcomes measure for end-of-life cancer care from the perspective of bereaved family members. We conducted three nationwide surveys in 1997, 2001, and 2007 (n = 850, 853, and 5,301, respectively). Although six of the 10 areas of the CES showed significant improvements between the two time points investigated, we identified considerable potential for further progress. Feedback from surveys of bereaved family members might help to improve the quality of end-of-life cancer care in inpatient PCUs. However, the effectiveness of feedback procedures remains to be confirmed. Furthermore, there is a need to extend the ongoing evaluation process to home care hospices and general hospitals, including cancer centers, identify the limitations of end-of-life care in all settings, and develop strategies to overcome them.

Abstract
The aim of this study was to develop a measure for evaluating good death from the bereaved family member's perspective, and to examine the validity and reliability of the assessment. A cross-sectional anonymous questionnaire was administered to bereaved family members of cancer patients who had died in a regional cancer center from September 2004 to February 2006. We measured the Good Death Inventory (GDI), Care Evaluation Scale, and an overall care satisfaction scale. A retest was conducted one month after sending the questionnaire. Of the 344 questionnaires sent to bereaved family members, 189 responses were analyzed (57%). A factor analysis of the responses to the GDI identified 10 core domains: "environmental comfort," "life completion," "dying in a favorite place," "maintaining hope and pleasure," "independence," "physical and psychological comfort," "good relationship with medical staff," "not being a burden to others," "good relationship with family," and "being respected as an individual." Eight optional domains also were identified: "religious and spiritual comfort," "receiving enough treatment," "control over the future," "feeling that one's life is worth living," "unawareness of death," "pride and beauty," "natural death," and "preparation for death." The GDI had sufficient concurrent validity with the Care Evaluation Scale and overall care satisfaction, sufficient internal consistency (alpha=0.74-0.95), and acceptable test-retest reliability (ICC=0.38-0.72). Finally, we developed a short version of the GDI. The GDI is a valid scale to measure end-of-life care comprehensive outcomes from the bereaved family member's perspective in Japan.

Abstract
This study aimed to clarify and compare the awareness and perceptions of the specialized inpatient palliative care service. A cross-sectional questionnaire survey was performed on the general population selected by stratified two-stage random sampling (n=2,548) and bereaved families who actually received specialized inpatient palliative care at 12 palliative care units (PCUs) in Japan (n=513). The respondents reported their awareness and perceptions of PCUs. Thirty-eight percent of the general population answered that they had "considerable" or "moderate" knowledge of PCUs, but 24% answered that they had "no" knowledge. Bereaved families who received PCU care (PCU-bereaved families) were likely to have better perceptions of PCUs than the general population: "alleviates pain" (68% of the general population and 87% of PCU-bereaved families agreed), "provides care for families" (67% and 86%, respectively), and "provides compassionate care" (67% and 87%, respectively). Both groups, however, expressed concerns about PCUs: "a place where people only wait to die" (30% and 40%, respectively) and "shortens the patient's life" (8% and 17%, respectively). These perceptions were associated with overall satisfaction with received care, and differed among the 12 PCUs. In conclusion, public awareness of PCUs was insufficient in Japan. Although PCU-bereaved families were generally likely to have better perceptions of PCUs than the general population, both groups shared concerns that a PCU was a place where people only wait to die. To facilitate appropriate use of specialized palliative care services, more efforts to inform the general population about the actual palliative care system are needed. In addition, the role of PCUs might be reconsidered in terms of the continuum of cancer care.

Abstract
CD45 is a haemopoietic tyrosine phosphatase, crucial for lymphocyte signalling. Two polymorphisms (C77G and A138G), which alter CD45 isoform expression, are associated with autoimmune and infectious diseases. Using HapMap data, we show that there is substantial linkage disequilibrium across the CD45 gene (PTPRC), with similar patterns in different populations. Employing a set of single nucleotide polymorphisms, correlated with a substantial proportion of variation across this gene, we tested for association with type 1 diabetes, Graves' disease in a Japanese population, hepatitis C in UK population and tuberculin response in a Chinese population. A limited number of common haplotypes was found. Most 138G alleles are present on only one haplotype, which is associated with Graves' disease, supporting previous data that A138G is a functionally important CD45 polymorphism.

Abstract
OBJECTIVES Palliative care specialists are faced with extensive barriers to providing effective palliative care. We carried out a survey to identify existing barriers from the point of view of palliative care experts in Japan and determine the priorities for future actions to overcome these barriers. METHODS We conducted a cross-sectional mail survey in December 2004. We sent out 2607 questionnaires to members of the Japanese Society of Palliative Medicine and Hospice Palliative Care Japan. We asked all respondents two open-ended questions regarding barriers and future actions in the context of palliative care in Japan. In total, 426 questionnaires were returned (response rate of 16%). RESULTS We identified 95 different answers concerning barriers to providing effective palliative care. The three most frequent answers were "general medical practitioners' lack of interest, knowledge, and skills" (n = 203), "general population's lack of knowledge and misunderstandings about palliative care" (n = 122), and "general medical practitioners' failure to provide information and lack of communication skills" (n = 89). We identified 136 different answers concerning future actions required to improve palliative care. The three most frequent answers were "organize study sessions on palliative care or case conferences in hospitals" (n = 122), "provide information about palliative care to the general population" (n = 117), and "in undergraduate education, make palliative care a compulsory course" (n = 88). CONCLUSIONS We identified numerous barriers to providing effective palliative care, related to not only medical practitioners, but also economic factors and the general population. These findings suggest that to overcome these barriers, we need to take action on many fronts, including increasing social awareness and effecting political change, as well as addressing problems relating to practitioners. We prioritized the future actions. The most frequent urgent problems were identified. We hope that collaborative efforts by the relevant organizations will improve palliative care in Japan.
