We conducted a preliminary study of the facial skin-improving effects of collagen-containing beverages as evaluated by objective indices. After obtaining written informed consent, 61 healthy females (age: 25–68, 34±8 y.o.) were randomly divided into two groups, receiving beverages containing 5 g (N=30) and 10 g (N=31), respectively, of collagen daily for one month. Facial skin moisture content and lower eyelid wrinkles were assessed before, 1 week and 1 month after consuming the test beverages. Results were analyzed of the 5 g and 10 g groups, as well as responder and non-responder groups. 10 g collagen beverages showed 50% effectiveness, and were more effective than the 5 g beverage; the effect was observable within 1 week. Furthermore, subjects with more wrinkles and drier skin showed greater benefit than those with higher facial skin moisture content and/or fewer wrinkles. It is suggested that a beverage containing 10 g collagen should be used for aged subjects with more wrinkles and/or drier skin for a period of 1–2 months in future randomized placebo-controlled trials of collagen-containing beverages.

PURPOSE: The purpose of this retrospective study was to determine the effects of resistance training (RT) on myocardial infarction (MI) patients in phase II cardiac rehabilitation (CR) in our hospital.
METHODS: Twenty two outpatients who had participated in the phase II CR program more than three months at least were enrolled in this study. They were divided into control group (n＝8) and RT group (n＝14). We examined changes in the exercise capacity of these two groups. The traditional exercise programs which included aerobics and muscle strength exercise were run on the control group. Changes in exercise load for target heart rate measured with a bicycle ergometer as an indicator of exercise capacity were assessed in each patient 1,3 and 5 months after AMI onset.
RESULTS: The amounts of load and target heart rates recorded 1 month after the onset were not significantly different between the two groups. After 3,5 months of CR, the RT group showed no changes in the target heart rate but significant increase of the amount of load. The control group showed no change in the amount of load and target heart rate. In the amount of each load 3 and 5 months after, the RT group was significantly out did the control group.
CONCLUSIONS: These results suggested that RT was useful in the improvement of exercise capacity for patients with MI who participated in the phase II CR program provided by our hospital.

The aim of this study is to collect the suggestions and recommendations of health care professionals involved in the regional palliative care program (OPTIM-study). A total of 101 multidisciplinary health care professionals who participated in the intervention program were interviewed, and 107 meaningful units were obtained from 89 valid interviews. The responses were categorized into “suggestions regardless of profession” (n=59), including “Participate in a multi-disciplinary conference to expand the network of people”, “Try to understand the situation of others”, “Seek support from others when you cannot solve the problem by yourself”, “Pursue all possibilities before giving up”, and “Do not try too hard”. As suggestions to those engaged in each profession, “Suggestions to community pharmacies” and “Suggestions to care managers” are frequently described. An examination of suggestions by the participants in the regional palliative care program could provide some insights to improve community palliative care.

The purpose of this study was to identify the greatest impact of the regional palliative care program on community health care professionals. Interviews were conducted involving 101 people who became involved in the intervention program implemented in 4 areas across Japan, and 96 valid responses were collected. The following were cited as the greatest impact: [I developed a network of people, and realized the importance of collaboration] (n＝61; “I was able to develop an interpersonal relationship” and “Now I understand the significance of collaboration”), [My knowledge and skills regarding palliative care were improved] (n＝18; “Knowledge and support helped me respond to patients with confidence” and “I have come to think that there is more to palliative care than terminal care”), [I rediscovered my role through a wide variety of experiences] (n＝10), [Both collaboration and palliative knowledge/skills meant a lot to me] (n＝4), [What I experienced in this program will help me play my role] (n＝2), and [Patients and their families became satisfied] (n＝1). The community palliative care program was most effective in facilitating collaboration, and helped participants develop knowledge and skills concerning palliative care.

Introduction: There has been no case report in which hyperpigmentation developed on the skin area where a transdermal fentanyl patch was applied in a patient. Case report: A 43-year-old man with recurrence of postoperative rectal cancer was treated by cetuximab plus irinotecan and panitumumab plus FOLFIRI. For cancer pain, transdermal fentanyl patch (Fentos®) was administered, and radiation from behind was performed. Hyperpigmentation then appeared on the chest and the abdominal skin sites where the patches were applied. The hyperpigmentation nearly disappeared four months after the fentanyl patch was discontinued. Discussion: The cause of the pigmentation was possibly due to post inflammatory hyperpigmentation secondary to contact dermatitis. It was desirable to conduct patch test and skin biopsy for making an accurate diagnosis. Conclusion: We should pay a careful attention to hyperpigmentation of the skin where a transdermal fentanyl patch is applied.

Although numerous studies have shown that each neuropsychological test is effective for diagnosing mild cognitive impairment (MCI) or Alzheimer’s disease (AD), studies comparing diagnostic accuracies of various neuropsychological tests are relatively rare and practical cutoff values are not available. The present study aimed to investigate the validity of neuropsychological tests and develop cutoff values for each in differentiating healthy control (HC), MCI and AD groups. A total of 84 HC, 187 with MCI and 195 with AD were evaluated by the selected seven neuropsychological tests using receiver operating characteristic (ROC) curve analysis. Logical Memory (LM) delayed recall (cutoff, 7) and Rey Auditory Verbal Learning Test (RAVLT) delayed recall (cutoff, 6) were effective for differentiating HC from MCI. To distinguish MCI and AD, Rey Osterrieth Complex Figure Test (ROCFT) 3 mindelayed recall (cutoff, 6) and LM immediate recall (cutoff, 4) were excellent. Delayed recall of verbal materials, as indexed by LM and RAVLT was sensitive for discriminating MCI from HC. Handling visual memory traces, as indexed by ROCFT and immediate verbal information by LM were sensitive for differentiating MCI and AD.

OBJECTIVE: This study was conducted to examine the effects of front-line chemotherapy on overall survival (OS) and postrecurrence survival (PRS) of patients with recurrent ovarian cancer, when stratifying the histologic type. METHODS: Five hundred and seventy-four patients with recurrent ovarian cancer with sufficient clinical information, including front-line chemotherapy, were analyzed. The pathologic slides were evaluated by central pathologic review. The patients were divided into two groups: group A (n=261), who underwent taxane plus platinum, and group B (n=313), who underwent conventional platinum-based chemotherapy without taxanes. RESULTS: The median age was 54 years (range, 14 to 89 years). Group A had significantly better median OS (45.0 months vs. 30.3 months, p<0.001) and PRS (23.0 months vs. 13.0 months, p<0.001) compared to group B. The OS and PRS were similar between the groups in patients with clear cell or mucinous histology. In contrast, among patients with non-clear cell, non-mucinous histologies, the OS and PRS of group A were significantly better than those of group B (OS, p<0.001; PRS, p<0.001). Multivariable analyses revealed that, among patients with non-clear cell, non-mucinous histologies, chemotherapy including taxane and platinum was an independent predictor of favorable survival outcomes. Conversely, in patients with clear cell or mucinous histology, taxane-including platinum-based combination chemotherapy did not improve the OS and PRS compared to a conventional platinum-based regimen which did not include taxanes. CONCLUSION: Since the emergence of taxane plus platinum, the prognosis of patients with recurrent ovarian cancer has improved. However, we here demonstrate that this improvement is limited to patients with non-clear cell, non-mucinous histologies.

Introduction：Hyponatremia, which is frequently present in patients with end-stage cancer, causes delirium and disturbance of consciousness and is considered a poor prognostic factor. We report a case of hyponatremia with hypopituitarism in association with leptomeningeal metastasis, resulting in reversible disturbance of consciousness. Case report：A 77 year-old female received chemotherapy at our hospital for postoperative recurrence of lung cancer, and best supportive care due to a side effect. After transfer to another hospital, she experienced a sudden disturbance of consciousness and was returned to our hospital. A detailed examination resulted in a diagnosis of hyponatremia from hypopituitarism following leptomeningeal metastasis involving the cerebral ventricles. Hyponatremia was improved by NaCl supplement and hormone replacement, followed by recovery from disturbance of consciousness. Discussion：QOL of patients with end-stage cancer can be improved through the active treatment of reversible causes of disturbance of consciousness. Conclusion：When severe hyponatremia is detected in cancer patients, it is important to consider the possibility of hypopituitarism with brain metastasis or meninges dissemination in the differential diagnosis.

Objective: To clarify the frequency of deficient mismatch repair (dMMR) in Japanese ovarian cancer patients, we examined microsatellite instability (MSI) status and immunohistochemistry (IHC) subtypes, including endometrioid carcinoma (EMC), clear cell carcinoma (CCC), or a mixture of both (Mix). Methods: We registered 390 patients who were diagnosed with EMC/CCC/Mix between 2006 and 2015 and treated at seven participating facilities. For 339 patients confirmed eligible by the Central Pathological Review Board, MSI, IHC, and MutL homolog 1 methylation analyses were conducted. The tissues of patients with Lynch syndrome (LS)-related cancer histories, such as colorectal and endometrial cancer, were also investigated. Results: MSI-high (MSI-H) status was observed in 2/217 CCC (0.9%), 10/115 EMC (8.7%), and 1/4 Mix (25%). Additionally, loss of MMR protein expression (LoE-MMR) was observed in 5/219 (2.3%), 16/115 (14.0%), and 1/4 (25%) patients with CCC, EMC, and Mix, respectively. Both MSI-H and LoE-MMR were found significantly more often in EMC (p<0.001). The median (range) ages of patients with MMR expression and LoE-MMR were 54 (30–90) and 46 (22–76) (p=0.002), respectively. In the multivariate analysis, advanced stage and histological type were identified as prognostic factors. Conclusion The dMMR rate for EMC/CCC was similar to that reported in Western countries. In Japan, it is assumed that the dMMR frequency is higher because of the increased proportion of CCC.

Background/Aims: Immune checkpoint blockade has recently been reported to be effective in treating microsatellite instability (MSI)-high tumors. Therefore, sufficient sampling of histological specimens is necessary in cases of unresectable pancreatic cancer (UR-PC). This multicenter study investigated the efficacy of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) using a Franseen needle for MSI evaluation in patients with UR-PC. Methods: A total of 89 patients with UR-PC who underwent endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) or EUS-FNB using 22-G needles at three hospitals in Japan (2018–2021) were enrolled. Fifty-six of these patients (FNB 23 and FNA 33) were followed up or evaluated for MSI. Patient characteristics, UR-PC data, and procedural outcomes were compared between patients who underwent EUS-FNB and those who underwent EUS-FNA. Results: No significant difference in terms of sufficient tissue acquisition for histology was observed between patients who underwent EUS-FNB and those who underwent EUS-FNA. MSI evaluation was possible significantly more with tissue samples obtained using EUS-FNB than with tissue samples obtained using EUS-FNA (82.6% [19/23] vs. 45.5% [15/33], respectively; p<0.01). In the multivariate analysis, EUS-FNB was the only significant factor influencing the possibility of MSI evaluation. Conclusions EUS-FNB using a Franseen needle is desirable for ensuring sufficient tissue acquisition for MSI evaluation.
