RESUMO
BACKGROUND: Colon capsule endoscopy (CCE), which became clinically applicable in 2006, is a simple and noninvasive procedure to evaluate colonic diseases; the accuracy of second-generation CCE, introduced in 2009, has dramatically improved. Currently, CCE is used as an alternative method for colorectal cancer screening, as well as for evaluating the mucosal lesions of inflammatory bowel disease, in cases where performing colonoscopy (CS) is difficult. However, the outcomes of CCE are uncertain. AIM: To investigate the outcomes of Japanese patients with negative findings (no polyps or colorectal cancer) on initial CCE. METHODS: This retrospective, single-center study was conducted at the Endoscopic Center at Aishinkai Nakae Hospital. This study included patients who underwent continuous CCE between November 2013 and August 2019, that exhibited no evidence of polyps or colorectal cancer at the initial CCE, and could be followed up using either the fecal immunochemical test (FIT), CS, or CCE. The observational period, follow-up method, presence or absence of polyps and colorectal cancer, pathological diagnosis, and number of colorectal cancer deaths were evaluated. RESULTS: Thirty-one patients (mean age, 60.4 ± 15.6 years; range, 28-84 years; 14 men and 17 women) were enrolled in this study. The reasons for performing the first CCE were screening in 12, a positive FIT in six, lower abdominal pain in nine, diarrhea in two, and anemia in two patients. The mean total water volume at the time of examination was 3460 ± 602 mL (2250-4800 mL), and a total CS was performed in 28 patients (90%). The degree of cleanliness was excellent in 15 patients and good in 16, and no poor cases were observed. No adverse events, such as retention or capsule aspiration, were observed in any of the patients. The mean follow-up period was 3.1 ± 1.5 years (range, 0.3-5.5 years). Follow-up included FIT in nine, CS in 20, and CCE in four patients (including duplicate patients). The FIT was positive in two patients, while CS revealed five polyp lesions (three in the ascending colon, one in the transverse colon, and one in the descending colon), with sizes ranging between 2 mm and 8 mm. Histopathological findings revealed a hyperplastic polyp in one patient, and adenoma with low grade dysplasia in four patients; colorectal cancers were not recognized. In the follow-up example by CCE, polyps and colorectal cancer could not be recognized. During the follow-up period, there were no deaths due to colorectal cancer in any of the patients. CONCLUSION: We determined the outcomes in patients with negative initial CCE findings.
RESUMO
Establishment of gold-standard chemotherapy and the subsequent development of salvage therapy have much improved the prognosis of patients with testicular germ cell cancer. However, not all patients with this disease get the best possible outcome in Osaka, Japan. A population-based study of testicular cancer cases diagnosed during 1993-1999 was performed using the Osaka Cancer Registry database to verify changes in prognosis and to examine their relationship with hospital procedure volume. Patients' referrals to hospitals during 1990-2001 were also examined to evaluate the degree of centralization. The 5-year relative survival rate of testicular cancer as well as testicular germ cell cancer in Osaka during 1993-1999 was markedly improved compared with that of previous periods (1975-1992); but remained lower than those reported in the EUROCARE-4 and Surveillance Epidemiology and End Results program. There appeared to be a significant association between survival and hospital procedure volume, even with adjustment made for clinical stage, age and histology. Centralization of referrals had not progressed during the past 12 years. In conclusion, the prognosis of testicular cancer in Osaka has improved remarkably, but nevertheless has remained lower than in the EU and/or the USA. Little progress has been made in centralization of hospital referrals.

Dietary factors are thought to be closely associated with the development of human cancers and hence numerous studies in this area have already been conducted in the United States and other Western countries. Comparatively few prospective studies have been published in Japan, especially for Hokkaido people. The present investigation was therefore performed to assess links between four leading cancers and some of the Japanese common dietary factors through a cohort study (1984-2002) in Hokkaido by analyzing 1,524 men and 1,634 women separately aged 40 and over. Adjusted Cox proportional hazard regression was used to calculate the relative risk (RR) for each dietary factor. For men, two dietary factors, miso soup (RR=0.2, 95% confidence interval (95%CI)=0.1-0.8) and pickled vegetables (RR=0.2, 95%CI=0.1-0.8) were associated with lower risk for stomach and colorectal cancer respectively. For women, three factors, namely salty confectionary (RR=3.5, 95%CI=1.1-10.9), black tea (RR=3.8, 95%CI=1.1-13.6), and carbonated drink/juice (RR=3.9, 95% CI=1.4-11.1) appeared related to an elevated risk of stomach cancer. However, further analysis simultaneously with all other adjusted factors indicated only carbonated drink/juice (RR=3.1, 95%CI=1.1-8.9) to present a significant risk factor for stomach cancer. One factor, namely wild edible plants (RR=3.3, 95%CI=1.1-9.8), increased the risk for colorectal cancer in women. None of the dietary components were significantly associated with lung or pancreatic cancers. This study also indicated a wide variation in the impact of dietary factors by sex and cancer site, in line with earlier work, pointing to a necessity for careful interpretation. Further epidemiological investigations by sex with more study subjects and confounding factors will be useful for determining the contribution of individual dietary factors to development of human cancers in Hokkaido, Japan.

OBJECTIVES: A prospective study was conducted to assess factors associated with risk of turnover among care workers in group homes (GHs) for elderly individuals with dementia. METHODS: In January, 2010, 51 out of 238 GHs in Sapporo City responded to our request for participation in a survey. During February and March of 2010, 438 out of 700 care workers (62.6%) in the GHs returned a completed questionnaire to us. They were followed up with until March of 2012, and 395 subjects (90.1%) responded to our survey, which was conducted twice. Over the course of 2 years, 91 subjects left their jobs. Cox's proportional hazards model was used for analysis, adjusting for gender and age. RESULTS: Less provision of social support by supervisors, colleagues, family or friends was significantly associated with increased risk of turnover. Financial aids for off-the-job training was marginally significantly associated with reduced risk of turnover. Longer duration of working for frail elderly care was significantly associated with decreased risk of turnover. Habitual smoking was significantly associated with increased risk of turnover. CONCLUSIONS: Social support in the workplace may be important to reduce the risk of turnover in care workers at GHs. Further prospective studies are required in other areas in Japan.

A cross-sectional study was conducted to explore the potential association between work environment and/or stress coping ability, and depressive status among caregivers working for "group homes (GHs)" in Japan. In January 2010, 438 out of 700 caregivers working at GHs in Sapporo City returned completed questionnaires to us. The questionnaires consisted of the Center of Epidemiological Scales-Depression, items about worker's attributions, Ozeki's coping scale, and so on. An analysis using a logistic regression model was used to find the associations adjusting for gender and age. Subjects who were 45 yr or older, had a spouse, had job training, a standard workload and scored high in emotion-oriented coping were significantly associated with a decreased risk of depression. Subjects who were less proud of their job, less willing to continue care for the frail elderly and had fewer acceptances by their supervisors or colleagues for consultation were significantly associated with an increased risk of depression. This study supports our hypothesis that there can be possible variables among individual factors, work environment and/or coping style for stress which may modulate a risk on the depressive status of caregivers.

OBJECTIVE: To evaluate the effects of localized irrigation with epinephrine saline after endoscopic retrograde cholangiopancreatography (ERCP). PATIENTS AND METHODS: One hundred and fourteen patients who underwent ERCP in our institute were treated with or without irrigation using epinephrine diluted in saline after ERCP to prevent post-ERCP pancreatitis. The serum amylase levels, white blood cell counts, and urine amylase levels were measured at 24 and 48 hours after ERCP. RESULTS: The treatment resulted in improvements in all items. A univariate analysis of the explanatory variables between the treatment and untreated groups revealed the treatment to be effective, but not statistically significant. Gender and cannulation of the pancreatic duct were the only variables with significant partial regression coefficients in the multiple regression model with all explanatory variables (p=0.045). When a stratified analysis was conducted using gender as a moderator variable, the treatment became a significant preventive factor (p=0.038), and cannulation of the pancreatic duct was a significant risk factor (p=0.027) in female patients. CONCLUSION: We suggest that irrigating with epinephrine saline into the papilla may be effective for preventing pancreatitis in female patients who received ERCP with cannulation of their pancreatic duct.
