Context Patients in the terminal stages of cancer are frequently affected by infection, especially pneumonia; but the effects of antibiotics on respiratory symptoms and factors associated with improvement are still unclear. Objectives This study aimed to clarify the effects of antibiotics on respiratory symptoms of terminally ill cancer patients with pneumonia, and to explore factors associated with the improvement. Methods This was a prospective cohort study in which we consecutively recruited terminally ill cancer patients diagnosed with pneumonia and treated with antibiotics at one of 23 palliative care units across Japan. At the baseline and Day 3, primarily responsible palliative care specialists recorded patient backgrounds, the results of physical and laboratory examination, and patient symptoms using the Support Team Assessment Schedule. Improvement was defined as improvement of dyspnea, cough, and sputum production on Day 3. Results Among all 1896 patients admitted during the study periods, 137 patients (7.2%) were enrolled into this study. Improvement was achieved in 65 patients (47.4%; 95% confidence intervals, 39–56). Univariate analyses revealed that the Palliative Prognostic Index (PPI), respiratory rate (RR), and oxygen requirement were significantly associated with the improvement. A multiple logistic regression analysis identified that PPI score of ≤ 6 and RR of Conclusion Antibiotics may relieve respiratory symptoms from pneumonia in approximately half of the terminally ill cancer patients. PPI and respiratory rate are useful to identify the patients who received benefits of antibiotics.

Background: Patients with life-limiting illnesses frequently experience urinary difficulties, and urinary catheterization is one of the interventions for managing them. However, evidence supporting the effects of urinary catheters on the quality of death (QoD) is lacking in this population. Objectives: To investigate whether urinary catheterization affects QoD in patients with advanced cancer in palliative care units. Design: A secondary analysis of a multicenter, prospective cohort study. Setting/Subjects: The study enrolled consecutive patients with advanced cancer admitted to palliative care units in Japan between January and December 2017. Those who were not catheterized on admission and who died while in a palliative care unit were analyzed. Measurements: QoD was evaluated at death using the Good Death Scale (GDS). Results: Of 885 patients, 297 (33.6%) were catheterized during their palliative care unit stay. Females and patients with a long palliative care unit stay were more likely to be catheterized. In inverse probability-weighted propensity score analysis, patients with urinary catheterization during their palliative care unit stay had higher total GDS scores than those without catheterization (coefficient 0.410, 95% confidence interval 0.068-0.752). In subgroup analyses stratified by sex, age, and length of palliative care unit stay, urinary catheterization was associated with higher total GDS scores in patients younger than 65 years of age and those who died after a palliative care unit stay of 21 days or fewer. Conclusions: This study suggested that urinary catheterization during a palliative care unit stay may have a positive impact on overall QoD in patients with advanced cancer. This study was registered in the UMIN Clinical Trials Registry (UMIN000025457).

Summary: Background & Aims: The prevalence of artificially administered nutrition and hydration (AANH) in different age groups among patients with advanced cancer remains unknown. The present study investigated the current utilization of AANH according to age groups in palliative care units. Methods: This was a secondary analysis of a prospective cohort study. We obtained information on primary nutritional administration routes during the first week of admission and data on the averaged calorie sufficiency rate or total calorie intake on the 7th day of admission. Patients were divided into five age groups (18–39, 40–59, 60–74, 75–89, and 90- years). Among patients receiving AANH, the proportions of higher-calorie AANH were compared between the five age groups. Results: A total of 1453 patients were included. The proportion of patients categorized as receiving nutrition and hydration via the parenteral route was the highest in the 18–39 and 40–59 groups (52.4 and 41.1%, respectively). Among patients receiving AANH (n = 534), the proportions of patients categorized into the

Parenteral morphine is widely used for dyspnea of imminently dying cancer patients (terminal dyspnea). However, the efficacy of other opioids such as oxycodone remains largely unknown.To explore the efficacy of parenteral oxycodone vs. morphine by continuous infusion over 24 hours in cancer patients with terminal dyspnea.This was a pre-planned subgroup analysis of a multicenter prospective observational study. Inclusion criteria were advanced cancer patients admitted to palliative care units, Eastern Cooperative Oncology Group performance status = 3-4, and a dyspnea intensity ≥2 on the Integrated Palliative care Outcome Scale (IPOS) for which oxycodone or morphine was initiated by continuous infusion. We measured dyspnea IPOS scores over 24 hours.We analyzed 164 patients who received oxycodone (n = 26) and morphine (n = 138) for dyspnea (median survival = 5 days). The mean age was 70 years, 58 patients (35%) had lung cancer, and 97 (59%) had lung metastases. Complete case analysis revealed that mean dyspnea IPOS scores decreased from 3.0 (standard deviation = 0.7) to 1.5 (0.7) in the oxycodone group (difference in means = 1.5; P 0.001), and from 2.9 (0.7) to 1.6 (1.0) in the morphine group (difference in means = 1.3; P 0.001). No significant between-group differences existed in the IPOS scores at 24 hours (P = 0.753). Adverse events were seen in no and 5 patients in the oxycodone and morphine groups, respectively.Parenteral oxycodone may be equally effective and safe as morphine in the treatment of terminal dyspnea in cancer patients. Future randomized controlled trials should confirm the efficacy and safety of opioids other than morphine for terminal dyspnea.

Background The appropriate timing of introducing the home-based nursing service to patients with advanced cancer has not been clarified. This study conducted a retrospective cohort study to investigate the associations of the early utilization of the home-based nursing service during chemotherapy with the place of care immediately after the last chemotherapy treatment in patients with advanced cancer. Methods Among the patients referred to the palliative care team of the University of Tsukuba Hospital between January 2018 and December 2019, patients with advanced cancer undergoing chemotherapy or before the start of chemotherapy at referral were included. The study patients who utilized the home-based nursing service during chemotherapy were classified into the early utilization group. The primary endpoint was the place of care immediately after the last chemotherapy treatment. Results Of the 1154 patients referred to the palliative care team during the study period, 261 were eligible for this study. Of these patients, 15.3% of patients (n = 40) received the home-based nursing service during chemotherapy. The proportion of patients transferred to home care after the last chemotherapy treatment was 17.5% in the early utilization group and 7.2% in the control group. The multivariate analysis revealed that the early utilization of the home-based nursing service during chemotherapy was significantly associated with the transfer to home care (odds ratio = 3.077; 95% confidence interval, 1.113–8.502). Conclusion The early utilization of the home-based nursing service during chemotherapy might be associated with the transfer to home care immediately after the last chemotherapy treatment.

Background: Studies on the appropriate use of urinary catheters for cancer patients at the end of life are limited. Aim: To clarify the differences among institutions in the prevalence of and indications for urinary catheterization of advanced cancer patients at palliative care units. Design: Pre-planned secondary analysis of a multicenter, prospective cohort study; East-Asian collaborative cross-cultural Study to Elucidate the Dying process (EASED). Setting/participants: This study enrolled consecutive advanced cancer patients admitted to palliative care units between January and December 2017. The final study group comprised 1212 patients from 21 institutions throughout Japan. Results: Out of the 1212 patients, 380 (31.4%; 95% confidence interval, 28.7%–34.0%) underwent urinary catheterization during their palliative care unit stay, and the prevalence of urinary catheterization in patients who died at palliative care units by institution ranged from 0.0% to 55.4%. When the 21 participating institutions were equally divided into three groups according to the institutional prevalence of catheterization, patients with difficulty in moving safely, exhaustion on movement, and restlessness or agitation were more likely to be catheterized in institutions with a high prevalence of catheterization than in those with a low or moderate prevalence ( p Conclusion: This study revealed that the institutional prevalence of urinary catheterization in advanced cancer patients at palliative care units widely varied. Further studies are needed to establish the appropriate use of urinary catheters, especially in patients with difficulty in moving safely, exhaustion on movement, and restlessness or agitation.

Background Many patients with advanced cancer diagnosed following emergency presentation will likely benefit from palliative care (PC) interventions. This study assessed the potential patient-related barriers to inpatient PC consultation among patients who were newly diagnosed with cancer after emergency admission (EA) and received only supportive care. Methods This observational study retrospectively obtained data on all patients who were admitted to our hospital after emergency transfer between January 2012 and November 2016. We identified patients for whom cancer was listed as the primary disease in the post-hospitalization discharge summary. Out of these patients, we selected those with newly diagnosed cancer and determined whether they were referred for inpatient PC consultation. Results This study recruited 141 patients with newly diagnosed cancer after EA (1.2% of all emergency transfer cases). Following diagnosis, the PC team intervened in 29.8% of all the patients enrolled in this study and in 53.3% of patients who received only supportive care. In patients who received only supportive care, the patients who were not referred for PC consultation were significantly more likely to have shorter survival time and less likely to receive disclosure about their cancer diagnosis than patients who were referred. Conclusions According to this study, short survival time and no disclosure of cancer diagnosis are potential patient-related barriers to inpatient PC consultation among patients with newly diagnosed cancer after EA.

Introduction Tapentadol has analgesic effects comparable to those of conventional opioids and is associated with fewer side effects, including gastrointestinal symptoms, drowsiness, and dizziness, than other opioids. However, the safety of tapentadol in the Japanese population remains unclear; the present multicentre study aimed to examine the safety of tapentadol and the characteristics of patients likely to discontinue this treatment owing to adverse events. Methods The safety of tapentadol was assessed retrospectively in patients with any type of cancer treated between August 18, 2014 and October 31, 2019 across nine institutions in Japan. Patients were examined at baseline and at the time of opioid discontinuation. Multivariate analysis was performed to identify factors associated with tapentadol discontinuation owing to adverse events. Results A total of 906 patients were included in this study, and 685 (75.6%) cases were followed up until tapentadol cessation for any reason. Among patients who discontinued treatment, 119 (17.4%) did so because of adverse events. Among adverse events associated with difficulty in taking medication, nausea was the most common cause of treatment discontinuation (4.7%), followed by drowsiness (1.8%). Multivariate analysis showed that those who were prescribed tapentadol by a palliative care physician (odds ratio [OR] 2.60, 95% confidence interval [CI] 1.36–4.99, p = 0.004), patients switching to tapentadol due to side effects from previous opioids (OR 2.19, 95% CI 1.05–4.56, p = 0.037), and patients who did not use naldemedine (OR 5.06, 95% CI 2.47–10.37, p

The benefits of artificial nutrition and hydration in patients with advanced cancer remain unknown. Therefore, we conducted a prospective study to evaluate effects of enteral nutrition (EN) and parenteral nutrition and hydration (PNH) on survival in palliative care units.This study involved a secondary analysis of a multicenter cohort study. Data of primary nutritional administration routes during the first week after admission (oral intake, enteral tube feeding, parenteral nutrition, parenteral hydration, poor oral intake) were obtained. Data of averaged calorie sufficiency rate/total calorie intake [high (75% ≤ or 750 kcal/day ≤), moderate (50-75% or 500-750 kcal/day), low (25-50% or 250-500 kcal/day), very low (25% or250 kcal/day)] were also obtained. After investigating the implementation of artificial nutrition and hydration, participants were divided into three groups according to the nutritional administration route and calorie sufficiency rate/total calorie intake: EN, PNH, and control. We conducted time-to-event analyses using the Kaplan-Meier method, log-rank test, and univariate and multivariate Cox regression analyses.Patients were divided into the EN group (n = 730), PNH group (n = 190), and control group (n = 533). Differences in survival rates among the three groups were significant (Log-rank P 0.001). Median survival times were 43.0 (95% CI 40-46), 33.0 (95% CI 29-37), and 15.0 (95% CI 14-16) days, respectively (P 0.001). In the multivariate-adjusted model, a significantly lower risk of mortality was observed in Cox's proportional hazard model in the EN group and PNH groups (HR 0.43 [95% CI 0.37-0.49], P 0.001; and HR 0.52 [95% CI 0.44-0.62], P 0.001, respectively) than in the control group.This study indicated the clinical benefits of EN and PNH for patients with advanced cancer. Nevertheless, managing symptoms to improve oral intake is essential before initiation of PNH, because EN was superior to PNH.

To determine factors related to the effectiveness of red blood cell transfusions in terminally ill cancer patients, we conducted a retrospective cohort study. We studied 27 terminally ill cancer patients who were transfused with red blood cells at our hospitalbetween June 2015 and September 2017. Patients who responded to the treatment("responders"; 16 cases[59%]) were compared with those who did not("non-responders"; 11 cases[40%]). Comparative predictive factor analysis revealed statistically significant differences between responders and non-responders in Eastern Cooperative Oncology Group performance status(PS)(p=0.004)and palliative prognostic index(PPI)scores(p=0.022). Furthermore, a statistically significant difference in median post-transfusion survivaltimes(MST)(p=0.047)was found between responders(69 days; quartile range: 20-141 days)and non-responders(22 days; quartile range: 11-47 days). These results suggested that PPI and PS were significant predictors of the effectiveness of red blood cell transfusions in palliative care, and transfusion effectiveness was related to post-transfusion survivaltime.

Tumor-related cancer pain often comprises mixed pain with both nociceptive and neuropathic components. Whether tumor-related cancer pain includes a neuropathic component impacts the therapeutic strategy. The aim of this cross-sectional study was to investigate the usefulness of two screening tools for neuropathic pain, painDETECT and Self-Report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS), in identifying the neuropathic component of mixed pain among patients with tumor-related cancer pain. This cross-sectional study recruited consecutive inpatients and outpatients at a single site. The diagnostic accuracy of painDETECT and S-LANSS was evaluated using receiver operating characteristic curve analysis and classification probability. Of the study group, 106 patients had tumor-related cancer pain. Analyses of the nociceptive and mixed pain groups (n = 104) showed that neither painDETECT nor S-LANSS had satisfactory areas under the curve (AUCs) for identifying the neuropathic component of mixed pain (0.59 for painDETECT and 0.56 for S-LANSS). By pain intensity, the AUC for painDETECT was significantly higher in the mild pain group than in the moderate or severe pain group (0.77 vs. 0.43, P = 0.002). All parameters of classification probability for both tools were higher in the mild pain group than in the moderate or severe pain group. painDETECT and S-LANSS could not identify the neuropathic component of mixed pain among patients with tumor-related cancer pain, especially when pain was moderate or severe. Contrarily, these screening tools might be useful for identifying the neuropathic component of mixed pain for mild pain.

The aim of the present study was to examine the associations of current smoking with five other unhealthy lifestyle behaviors among urban civil servants in Japan according to sex and occupational category. The study included 10,232 urban civil servants in Japan who presented for a health check-up in 2011. We analyzed data on anthropometric measurements and self-reported lifestyle factors. Current smokers had a higher BMI than never smokers in white-collar workers, but not in blue-collar workers of both sexes. There were strong associations of current smoking with irregular breakfasting regardless of sex and occupational category. In males, current smokers were less likely to take exercise than ex-smokers in both occupational categories. The associations of current smoking with other unhealthy behaviors were modified by sex and occupational category. These results are useful for understanding the health risks among smokers according to sex and occupational category.

Occupation could affect the distribution of smoking status of workers, and the success of smoking cessation among workers depends partly on worksite conditions. Blue collar workers have been identified as a high-risk group for smoking. The aim of the present study was to examine trends in smoking rates among urban civil servants in Japan according to occupational categories. Subjects were urban civil servants aged 30–59 years. They annually reported smoking status in a questionnaire in a worksite health check-up each year from 2004 to 2011. Urban civil servants reported substantially lower current smoking rates than national smoking rates in Japan (20.2%, 23.8%, and 27.0% for males in their 30s, 40s, and 50s and 2.4%, 6.3%, and 9.5% for females, respectively, in 2011). In analysis by occupational categories, current smoking rates declined among all groups except female white collar workers in their 50s. The current and persistent smoking rates (number of current smokers/[number of ex-smokers and current smokers]) among blue collar workers were higher than those among white collar workers at almost all time points in all age and gender groups. This study found relatively lower current smoking rates among urban civil servants than the national average and higher current and persistent smoking rates in blue collar workers than in white collar workers among them. These results would help to make suitable worksite smoking cessation policies for each occupational category.

Prostate specific antigen (PSA) testing plays a major role in prostate cancer screening; however, the low positive predictive value of PSA testing leads to many unnecessary biopsies. Genetic background is one of factors that could cause it. That’s why an association between genetic background and PSA levels should be elucidated. This study aimed to investigate whether DPP4 genetic variants are associated with baseline PSA levels. A cross-sectional study was performed on 2,074 Japanese men aged between 35 and 69 in the Shizuoka area from the Japan Multi-institutional Collaborative Cohort (J-MICC) Study. Three DPP4 tagging single nucleotide polymorphisms (SNPs) were selected for genotyping: rs3788979 (A/G), rs7608798 (T/C), and rs2268889 (A/G). Higher mean serum PSA levels were significantly associated with an increase in the number of the rs7608798 C allele (p for trend = 0.02). A stratified analysis by age groups demonstrated that PSA levels had positive significant trends with the numbers of the minor alleles of rs3788979 or rs7608798 in the oldest group (men aged between 60 and 69) (p for trend=0.004 for rs3788979 and p for trend=0.001 for rs7608798). Haplotype analysis showed that the C-A (rs7608798-rs2268889) haplotype was significantly associated with increased PSA levels (p=0.006), compared with the most common haplotype, T-A. In summary, our study suggests that DPP4 genetic variants influence baseline PSA levels, especially in men aged between 60 and 69.

Background Nitric oxide is a key molecule not only in the cardiovascular system, but also in the metabolic-endocrine system. The purpose of this study was to examine possible associations of the NOS3 T-786C polymorphism (rs2070744) with serum lipid levels on the basis of lifestyle factors for tailoring prevention of dyslipidemia. Methods For this cross-sectional study, a total of 2226 subjects aged 35 to 69 years (1084 men and 1142 women) were selected from Japanese participants in the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study. They were recruited in eight areas throughout Japan between February 2004 and November 2008. Results In a stratified analysis by leisure-time physical activity, the likelihood of hypertriglyceridemia (serum triglyceride levels ≥ 150 mg/dL) among subjects with the C allele was significantly lower than those without it in the active group (OR = 0.43, 95% CI = 0.22-0.84 in the fasting group), but not in the sedentary group. A gene-environment interaction between the T-786C polymorphism and leisure-time physical activity for hypertriglyceridemia was significant (P = 0.007 in the fasting group). Additionally, serum triglyceride levels (mean ± SD) across leisure-time physical activity classes decreased significantly only in the TC + CC genotype group (111 ± 60 mg/dL for sedentary, 95 ± 48 mg/dL for moderately active, 88 ± 44 mg/dL for very active, P for trend = 0.008 in the fasting group), but not in the TT genotype group. Total cholesterol, high-density lipoprotein (HDL) cholesterol, and non-HDL cholesterol levels had no significant association with the polymorphism. Conclusions This study suggests that the NOS3 T-786C polymorphism modifies the effect of leisure-time physical activity on serum triglyceride levels.

A genome-wide association study identified that LRP2 rs2544390 in intron 1 was associated with serum uric acid (SUA) levels among Japanese, as well as polymorphisms of SLC22A12, ABCG2, and SLC2A9. This study aimed to confirm the association of rs2544390 C/T with SUA, as well as another LRP2 polymorphism (rs3755166 G/A) in the promoter. Subjects were 5016 health checkup examinees (3409 males and 1607 females) aged 35 to 69years with creatinine
