- Background Fruit and vegetable intakes have been associated with a reduced risk of colon cancer; however, in more recent studies associations have been less consistent. Statistical power to examine associations by colon site has been limited in previous studies. Methods Fruit and vegetable intakes in relation to colon cancer risk were examined in the Pooling Project of Prospective Studies of Diet and Cancer. Relative risks (RRs) and 95% confidence intervals (Cis) were estimated separately in 14 studies using Cox proportional hazards model and then pooled using a randomeffects model. Intakes of total fruits and vegetables, total fruits, and total vegetables were categorized according to quintiles and absolute cutpoints. Analyses were conducted for colon cancer overall and for proximal and distal colon cancer separately. All statistical tests were two-sided. Results Among 756217 men and women followed for up to 6 to 20 years, depending on the study, 5838 were diagnosed with colon cancer. The pooled multivariable RRs (95% Cis) of colon cancer for the highest versus lowest quintiles of intake were 0.91 (0.82 to 1-01 1 P-trend =.19) for total fruits and vegetables, 0.93 (0.85 to 1.02, P-trend =.28) for total fruits, and 0.94 (0.86 to 1.02, P-trend =.17) for total vegetables. Similar results were observed when intakes were categorized by identical absolute cut points across studies (pooled multivariable FIR = 0.90, 95% CI = 0.77 to 1.05 for 800 or more versus <200 g/day of total fruits and vegetables, P-trend =.06). The age-standardized incidence rates of colon cancer for these two intake categories were 54 and 61 per 100000 person-years, respectively. When analyzed by colon site, the pooled multivariable RRs (95% Cis) comparing total fruit and vegetable intakes of 800 or more versus less than 200 g/day were 0.74 (0.57 to 0.95, P-trend =.02) for distal colon cancers and 1.02 (0.82 to 1.27, P-trend =.57) for proximal colon cancers. Similar site-specific associations were observed for total fruits and total vegetables. Conclusion Fruit and vegetable intakes were not strongly associated with colon cancer risk overall but may be associated with a lower risk of distal colon cancer.

- To evaluate the associations between intakes of vitamins A, C, and E and risk of colon cancer. Using the primary data from 13 cohort studies, we estimated study- and sex-specific relative risks (RR) with Cox proportional hazards models and subsequently pooled RRs using a random effects model. Among 676,141 men and women, 5,454 colon cancer cases were identified (7-20 years of follow-up across studies). Vitamin A, C, and E intakes from food only were not associated with colon cancer risk. For intakes from food and supplements (total), the pooled multivariate RRs (95% CI) were 0.88 (0.76-1.02, > 4,000 vs. a parts per thousand currency sign1,000 mu g/day) for vitamin A, 0.81 (0.71-0.92, > 600 vs. a parts per thousand currency sign100 mg/day) for vitamin C, and 0.78 (0.66-0.92, > 200 vs. a parts per thousand currency sign6 mg/day) for vitamin E. Adjustment for total folate intake attenuated these associations, but the inverse associations with vitamins C and E remained significant. Multivitamin use was significantly inversely associated with colon cancer risk (RR = 0.88, 95% CI: 0.81-0.96). Modest inverse associations with vitamin C and E intakes may be due to high correlations with folate intake, which had a similar inverse association with colon cancer. An inverse association with multivitamin use, a major source of folate and other vitamins, deserves further study.

- Background: Telemonitoring of heart failure (HF) patients is increasingly discussed at conferences and addressed in research. However, little is known about actual use in specific countries. Objective: We aimed to (1) describe the use of non-invasive HF telemonitoring, (2) clarify expectations of telemonitoring among cardiologists and nurses, and (3) describe barriers to the implementation of telemonitoring in Japan and Sweden. Methods: This study used a cross-sectional survey of non-invasive HF telemonitoring. A total of 378 Japanese (120 cardiologists, 258 nurses) and 120 Swedish (39 cardiologists, 81 nurses) health care professionals from 165 Japanese and 61 Swedish hospitals/clinics nationwide participated in the study (210 in Japan and 98 in Sweden were approached). Data were collected between November 2013 and May 2014 with a questionnaire that was adapted from a previous Dutch study on telemonitoring. Results: The mean age of the cardiologists and nurses was 47 years and 41 years, respectively. Experience at the current position caring for HF patients was 19 years among the physicians and 15 years among the nurses. In total, 7 Japanese (4.2%) and none of the Swedish health care institutions used telemonitoring. One fourth (24.0%, 118/498) of the health care professionals were familiar with the technology (in Japan: 21.6%, 82/378; in Sweden: 30.0%, 36/120). The highest expectations of telemonitoring (rated on a scale from 0-10) were reduced hospitalizations (8.3 in Japan and 7.5 in Sweden), increased patient self-care (7.8 and 7.4), and offering high-quality care (7.8 and 7.0). The major goal for introducing telemonitoring was to monitor physical condition and recognize signs of worsening HF in Japan (94.1%, 352/374) and Sweden (88.7%, 102/115). The following reasons were also high in Sweden: to monitor effects of treatment and adjust it remotely (86.9%, 100/115) and to do remote drug titration (79.1%, 91/115). Just under a quarter of Japanese (22.4%, 85/378) and over a third of Swedish (38.1%, 45/118) health care professionals thought that telemonitoring was a good way to follow up stable HF patients. Three domains of barriers were identified by content analysis: organizational barriers "how are we going to do it?" (categories include structure and resource), health care professionals themselves "what do we need to know and do" (reservation), and barriers related to patients "not everybody would benefit" (internal and external shortcomings). Conclusions: Telemonitoring for HF patients has not been implemented in Japan or Sweden. However, health care professionals have expectations of telemonitoring to reduce patients hospitalizations and increase patient self-care. There are still a wide range of barriers to the implementation of HF telemonitoring.

- Background: Improving quality of life (QOL) has become an important goal in left ventricular assist device (LVAD) therapy. We aimed (1) to assess the effect of an implantable LVAD on patients QOL, (2) to compare LVAD patients QOL to that of patients in different stages of heart failure (HF), and (3) to identify factors associated with patients QOL.Methods and Results: The QOL of 33 Japanese implantable LVAD patients was assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and Short-form 8 (SF-8), before and at 3 and 6 months afterwards. After LVAD implantation, QOL significantly improved [MLHFQ, SF-8 physical component score (PCS), SF-8 mental component score (MCS), all Pless than0.05]. Implanted LVAD patients had a better QOL than extracorporeal LVAD patients (n=33, 32.1 +/- 21.9 vs. n=17, 47.6 +/- 18.2), and Stage D HF patients (n=32, 51.1 +/- 17.3), but the score was comparable to that of patients who had undergone a heart transplant (n=13). In multiple regression analyses, postoperative lower albumin concentration and right ventricular failure were independently associated with poorer PCS. Female sex and postoperative anxiety were 2 of the independent factors for poorer MCS (all Pless than0.05).Conclusions: Having an implantable LVAD improves patients QOL, which is better than that of patients with an extracorporeal LVAD. Both clinical and psychological factors are influence QOL after LVAD implantation.

- Background: The role of caregivers is important for the successful support of left ventricular assist device (LVAD) patients. We aimed to (1) evaluate quality of life (QoL) of caregivers pre-and post-LVAD implant and (2) identify factors associated with caregivers QoL. Methods: The caregivers QoL was assessed with the Short Form-8 before implant, at 3 and 6 months after LVAD implantation. The physical and mental component summary (PCS and MCS) scores were calculated. Caregiver burden was evaluated using the 8-item Zarit Caregiver Burden Interview. Results: Data were collected from LVAD patients as bridge-to-transplant and their family caregivers in Japan. No significant changes were found in caregivers PCS scores during the follow-up (before 52.7 +/- 7.1; at 3 months 49.7 +/- 6.5, and at 6 months 50.7 +/- 6.4, n = 20). Compared with the scores before implant (38.9 +/- 9.3), the caregivers MCS scores improved after LVAD implantation at 3 months (44.2 +/- 7.7; p = 0.03) and at 6 months (46.2 +/- 7.4, p = 0.003), but they were still lower than those of the Japanese general population (p amp;lt; 0.01). In multiple regression analysis at 3 months (n = 40), caregivers lower PCS scores were associated with older patient age [standard partial regression coefficients (s beta) = -0.36, p = 0.02] and caregiver unemployment (s beta = 0.30, p = 0.04), whereas being female (s beta = -0.26, p = 0.03), being the patients spouse (s beta = -0.23, p = 0.03), and having a mild to moderate caregiving burden (s beta = -0.63, p amp;lt; 0.001) were associated with lower MCS scores among caregivers. Conclusions: LVAD implantation improves caregivers mental QoL. Since caregivers MCS scores are lower than the general population, it is important to identify family caregivers at risk for low QoL and reduce their caregiving burden.
