Eating-related distress in advanced cancer patients with cachexia and family members: a survey in palliative and supportive care settings.

PURPOSE: Few studies have investigated nutrition impact symptoms and eating-related distress among advanced cancer patients and their families. This is a questionnaire survey to examine the severity of nutrition impact symptoms and the prevalence of eating-related distress among them in palliative and supportive care settings. METHODS: Questionnaires for patients and their families were preliminarily developed. We selected 16 common symptoms of advanced cancer, i.e., 9 symptoms of the ESAS-r and 7 of the PG-SGA. Each questionnaire concerning eating-related distress consisted of 12 items. RESULTS: A total of 140 out of 147 patients responded (95.2%). They were classified into two groups: (1) non-cachexia/pre-cachexia (n = 57) and (2) cachexia/refractory cachexia (n = 83). The top 3 out of 16 symptoms in all patients were feeling of well-being, lack of appetite, and tiredness. Significant differences were observed in 8 symptoms between the two groups: tiredness (p = 0.007), drowsiness (p = 0.007), lack of appetite (p < 0.001), early satiety (p = 0.001), diarrhea (p = 0.025), abnormal taste (p = 0.02), difficulty swallowing (p = 0.002), and feeling of well-being (p = 0.003). Regarding eating-related distress in patients, significant differences were observed in all items, except for 2, between the two groups. Concerning eating-related distress in families, significant differences were observed in all items between the two groups. CONCLUSION: Advanced cancer patients with cachexia have more severe nutrition impact symptoms than those without cachexia, and patients with cachexia and their families have greater eating-related distress than those without cachexia.

Perception of need for nutritional support in advanced cancer patients with cachexia: a survey in palliative care settings.

PURPOSE: Few studies have investigated the need for nutritional support in advanced cancer patients in palliative care settings. Therefore, we conducted a questionnaire to examine the relationship between the perception of need for nutritional support and cancer cachexia and the prevalence of specific needs, perceptions, and beliefs in nutritional support. METHODS: We conducted a questionnaire in palliative care settings. Patients were classified into two groups: (1) non-cachexia/pre-cachexia and (2) cachexia/refractory cachexia. RESULTS: A total of 117 out of 121 patients responded (96.7%). A significant difference was observed in the need for nutritional support between the groups: non-cachexia/pre-cachexia (32.7%) and cachexia/refractory cachexia (53.6%) (p = 0.031). The specific needs of patients requiring nutritional support were nutritional counseling (93.8%), ideas to improve food intake (87.5%), oral nutritional supplements (83.0%), parenteral nutrition and hydration (77.1%), and tube feeding (22.9%). The top perceptions regarding the best time to receive nutritional support and the best medical staff to provide nutritional support were "when anorexia, weight loss, and muscle weakness become apparent" (48.6%) and "nutritional support team" (67.3%), respectively. The top three beliefs of nutritional treatments were "I do not wish to receive tube feeding" (78.6%), "parenteral nutrition and hydration are essential" (60.7%), and "parenteral hydration is essential" (59.6%). CONCLUSIONS: Patients with cancer cachexia expressed a greater need for nutritional support. They wished to receive nutritional support from medical staff when they become unable to take sufficient nourishment orally and the negative impact of cachexia becomes apparent. Most patients wished to receive parenteral nutrition and hydration.

Need for nutritional support, eating-related distress and experience of terminally ill patients with cancer: a survey in an inpatient hospice.

OBJECTIVES: Cancer cachexia creates a large burden for terminally ill patients with cancer. The main causes are a lack of knowledge of cancer cachexia and unsuccessful attempts to increase body weight. The role of nutritional support has not been clarified, and patients' eating-related distress is poorly understood. There has been no study investigating into needs for nutritional support in an inpatient hospice. The primary aim of this study was to explore needs for nutritional support, eating-related distress and patients' experiences. METHODS: A survey was conducted involving 60 patients with advanced cancer in an inpatient hospice. We first asked about need for nutrition therapy in the inpatient hospice. We then asked whether patients had unmet needs for four items. The last question was composed of 19 items concerning patients' experience of eating-related distress. RESULTS: Thirty-seven patients responded (62%). Most of the patients, 28 of 37 (76%), had general unmet needs for nutrition therapy for cancer cachexia, and more than half needed specific support, such as 'attention' and 'explanation'. The top 5 of the 19 items were mainly about daily diet, nutrition and losing weight. Of these, the top four belonged to the group of coping strategies and the fifth to the group of mechanisms originating from patients themselves. CONCLUSIONS: A number of terminally ill patients with cancer admitted to an inpatient hospice had need for nutritional support and experienced high levels of eating-related distress.

A Negative Feedback Loop Controlling bHLH Complexes Is Involved in Vascular Cell Division and Differentiation in the Root Apical Meristem.

Controlling cell division and differentiation in meristems is essential for proper plant growth. Two bHLH heterodimers consisting of LONESOME HIGHWAY (LHW) and TARGET OF MONOPTEROS 5 (TMO5)/TMO5-LIKE1 (T5L1) regulate periclinal cell division in vascular cells in the root apical meristem (RAM). In this study, we further investigated the functions of LHW-T5L1, finding that in addition to controlling cell division, this complex regulates xylem differentiation in the RAM via a novel negative regulatory system. LHW-T5L1 upregulated the thermospermine synthase gene ACAULIS5 (ACL5), as well as SUPPRESSOR OF ACAULIS5 LIKE3 (SACL3), which encodes a bHLH protein, in the RAM. The SACL3 promoter sequence contains a conserved upstream open reading frame (uORF), which blocked translation of the main SACL3 ORF in the absence of thermospermine. Thermospermine eliminated the negative effect of uORF and enhanced SACL3 production. Further genetic and molecular biological analyses indicated that ACL5 and SACL3 suppress the function of LHW-T5L1 through a protein-protein interaction between LHW and SACL3. Finally, we showed that a negative feedback loop consisting of LHW-T5L1, ACL5, SACL3, and LHW-SACL3 contributes to maintain RAM size and proper root growth. These findings suggest that a negative feedback loop regulates the LHW-T5L1 output level to coordinate cell division and differentiation in a cell-autonomous manner.

Association between early palliative care referrals, inpatient hospice utilization, and aggressiveness of care at the end of life.

BACKGROUND: Palliative care has a positive effect on many clinical outcomes, yet most referrals to palliative care have occurred late. End-of-life (EOL) cancer care has become increasingly aggressive. There have been no studies investigating the association between early palliative care referrals and aggressive EOL care in Japan. OBJECTIVE: This study was designed to explore the association between early palliative care referrals, inpatient hospice utilization, and aggressiveness of EOL care by investigating cancer decedents. DESIGN: A retrospective cohort study in a cancer-designated hospital in Japan. SETTING/SUBJECTS: This study examined 266 consecutive cancer decedents. Inclusion criteria were adults and patients who died from cancer or causes related to cancer. Patients who died from causes unrelated to cancer were excluded. A total of 265 patients met the criteria. MEASUREMENTS: We explored the association between early referrals (>3 months before death) and inpatient hospice utilization and the relationship between the timing of referrals and aggressive EOL care measured by a composite score adapted from Earle and colleagues. RESULTS: Patients were divided into an early referral group (n=54) and a control group (n=211). The rate of inpatient hospice utilization was significantly higher in the early referral group (74% versus 47%, adjusted p<0.001). While each of six indicators of aggressiveness of EOL care did not differ significantly, the composite score was significantly lower in the early referral group (1.91±0.59 versus 2.14±0.78, adjusted p<0.001). CONCLUSIONS: Early palliative referrals were associated with more inpatient hospice utilization and less aggressive EOL care.

Assessment of Intervention by a Palliative Care Team Working in a Japanese General Hospital: A Retrospective Study.

Our objective was to explore the effectiveness of a palliative care team (PCT) by investigating potential differences in opioid prescription between patients who had had PCT involvement before admission to an inpatient hospice and those who had not. A total of 221 patients met the criteria; they were divided into an intervention group (n = 140) and a control group (n = 81). The daily dose of opioid before admission to the hospice was significantly higher in the intervention group (P < .001). The difference between the maximum opioid dose and the initial dose, the rate of increase in opioids until death, and the length of stay in the hospice were not significantly different between the groups. A PCT contributes to more appropriate use of opioids before admission to a hospice.

A bHLH complex activates vascular cell division via cytokinin action in root apical meristem.

Higher organisms possess mechanisms to maintain stem cells' proliferative and pluripotent states in stem cell niches [1]. Plants possess two types of stem cell niches in the root and shoot apical meristems, where regulatory interactions exist between stem cells and organizing cells. Recent studies provided new insights into the molecular mechanism of stem cell maintenance [2-4]. However, earlier and more essential developmental events such as the acquisition of stem cell proliferative activity are still unknown. In vascular tissues, procambial cells function as stem cells and differentiate into xylem, phloem, and procambium. Procambial cell proliferation starts at root apical meristem (RAM) postembryonically; therefore, procambial cell development in RAM is a good model for investigating the regulation of stem cell proliferation. LONESOME HIGHWAY (LHW) and TARGET OF MONOPTEROS5 (TMO5), as well as its homolog, TMO5-LIKE1 (T5L1), encode bHLH proteins that function as heterodimers (LHW-TMO5 and LHW-T5L1) in vascular tissue organization [5-7]. LHW-T5L1 promotes vascular-cell-specific proliferation in RAM [7]. Here, we demonstrate that LHW-T5L1 promotes expression of key cytokinin production genes, including LONELY GUY3 (LOG3) and LOG4, in xylem precursor cells, resulting in elevated cytokinin levels in the surrounding cells. LHW-T5L1 can also promote expression of AHP6, which suppresses cytokinin signaling and then maintains xylem precursor cells at a nondividing state. Our results indicate that LHW-T5L1 establishes xylem precursor cells as a signal center that promotes procambial-cell-specific proliferation through cytokinin response.

[Palliative chemotherapy in cancer patients].

Palliative chemotherapy is applied for incurable cancer patients to prolong their survival, decrease their cancer-related symptoms, and improve their quality of life. These are important end points in clinical trials of palliative chemotherapy. A lot of clinical studies have demonstrated the palliative effect of chemotherapy for incurable cancers such as advanced pancreatic cancer, non-small cell lung cancer and so on. On the other hand, treatment with anti-cancer drugs can be harmful, and sometimes the toxicities may be very severe leading to worsened quality of life and shortened survival. So, we must carefully consider the application of palliative chemotherapy and discuss it with patients.
