Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is introduced as a modified two staged hepatectomy for advanced liver malignancies,which requires extended hepatectomy with very small future remnant liver volume.It is characterized by rapid and large growth of future remnant liver and potential of widening the indication of curative resection with extended major hepatectomy for liver malignancies.However,it showed much higher morbidity of complications and mortality than extended hepatectomy after portal vein embolization.The development of ALPPS is often controversial.In this article,the development and problems of ALPPS are retrospected and summarized,in order to reflect the role of ALPPS in Japan where zero mortality after hepatectomy is highly expected.

The two books, “Hyakuchin-ikkan” and “Dr. Toukaku’s Houyo and it’s hearing”, have long been believed to have written by Toukaku Wada (A famous doctor in the Edo period). However, their medical recipes and the way they perceive disease were extremely different from those in Toukaku’s other publications. Interestingly, however, they closely resemble the contents of “Houyogei” written by Keiri Arimochi (also a famous doctor in Edo period). In this study, therefore, we set out to resolve this conundrum. We researched other books of Toukaku more deeply, but we were unable to find any commonalities between the two books in question and the other books of Toukaku. On the other hand, We found the name Dr. Kyourin multiple times in “Hyakuchin-ikkan,” and we posited that Kyourin was the real author of that book. Moreover, while we found Kyourin to be an alias of Keiri, there was no evidence of Toukaku being the Dr. Kyourin. In addition, we confirmed that “Toukaku’s Houyo” is the predecessor and model for Keiri’s one. We thus determined that both books, “Hyakuchin-ikkan” and “Toukaku’s Houyo and it’s hearing,” were based on the medical experiences of Keiri Arimochi and not those of Toukaku Wada.

The engaging>30 minutes of physical activity (PA) at 4-6 METs has been recommended for the prevention of cardiovascular disease. We determined whether relatively low intensity (i. e., 3-5 METs) PA inhibits the age-related central arterial stiffening, a risk of cardiovascular disease. In the cross-sectional study, the association between carotid arterial properties (via ultrasound system) and daily PA (via electric accelerometer) were studied in 172 normotensive people (41-82 yrs). People engaging>30 min/day of PA corresponding to 3-5 METs had a significantly lower beta-stiffness index than sedentary peers after adjusting for covariates (i. e., age and PA time at more than 6 METs). In the interventional study, beta-stiffness index of nine normotensive postmenopausal women was significantly decreased after the 12-week aerobic training (cycling at 80% of ventiratory threshold, ≈4 METs, 30 min/day, 5 days/week). These results suggest that the increase in daily PA at 3-5 METs inhibits the age-related carotid arterial stiffening.

Resistance exercise in the elderly and patients with a cardiovascular disorder has been thought to have a high cardiovascular risk, because it has the tendency to cause an excessive rise in blood pressure and induce serious arrhythmia. But recently, resistance exercise has been introduced into physical therapy because the safety of such exercise has been confirmed in subjects without a cardiovascular disorder.
The purpose of this study was to investigate the safety of lower extremity resistance exercise in middle-aged or elderly subjects with hypertension and receiving medical treatment (n=24), and those without hypertension (n=40), by measuring cardiovascular response during resistance exercise of different loads (40% and 60% 1 RM), and usefulness of respiratory guidance during such exercise.
As a result, there was no difference in diastolic blood pressure between those with and without hypertension ; but systolic blood pressure and rate pressure product both at rest and during exercise were significantly greater in patients with hypertension. However, neither group showed symptoms of angina, ischemic signs in ECG, or serious arrhythmia ; and there was no difference in the frequency of excessive rise in blood pressure between the groups (2 subjects with hypertension and 1 subject without hypertension) . Blood pressure during exercise was significantly lowered by respiratory guidance.
These results show that it is important to measure blood pressure during exercise before resistance exercise training regardless of the presence of hypertension, although an excessive rise in blood pressure occurred in only a few subjects. Furthermore, it is important to exhale slowly and not hold one's breath during exercise.

Arterial compliance progressively decreases with aging. This aging-induced reduction of arterial compliance causes an increase of systolic blood pressure (SBP), whereas regular exercise increases arterial compliance. We hypothesized that an increase in daily physical activity (DPA) produces a beneficial effect on systemic arterial compliance (SAC ; an index of central arterial compliance) and this phenomenon could decrease SBP in the elderly. We investigated the relationship among DPA, SAC, SBP, diastolic blood pressure (DBP), and some other risk factors for cardiovascular and/or cerebrovascular events (total cholesterol, HDL-cholesterol, and HOMA-R) cross-sectionally in 127 elderly persons (42 male, 85 female : aged 74±4 years) . The DPA was estimated by expended calories using an accelerometer. The SAC was calculated from a finger pulse pressure waveform recorded by using PORTAPRES ; and stroke volume obtained from the same pressure waveform based on the volume-clump method. The analyses demonstrated that SBP was directly and decreasingly affected by SAC, and that DPA had an increasing effect on SAC. Furthermore, SBP was directly and increasingly affected by DBP, and DBP was directly and decreasingly affected by both SAC and DPA. Therefore, it is considered that DPA may have suppressive effects on the rise of SBP through the indirect effects of changing SAC and DBP. These findings suggest that an increase in DPA could improve the age-induced reduction of arterial compliance and rise of SBP in elderly humans.

Objective: This study aimed to investigate the effect of nutritional status on estimated fentanyl absorption in cancer patients being treated with a fentanyl transdermal patch (FP), by measuring the residual fentanyl content in used patches. Methods: 24 adult Japanese inpatients receiving FP treatment for chronic cancer-related pain were enrolled. During FP application, the nutritional risk of the patients was measured using the Malnutrition Universal Screening Tool (MUST) and Nutritional Risk Screening 2002 (NRS 2002), both of which are nutrition screening tools used widely in Japan. We then classified the patients into low-, medium-, and high-risk groups according to the nutritional risk measured by MUST, and compared the transdermal fentanyl delivery efficiency (FE) between that groups. Results: The FE, which is estimated by the residual fentanyl content in used FPs collected from the patients, was found to be decreased in the high-risk group. According to NRS 2002, the mean transdermal fentanyl delivery efficiency in the high-risk group was significantly lower than that in the low-risk group. Conclusion: These results showed that changes in nutritional status affect FE, and that poor nutritional status might decrease transdermal fentanyl absorption in cancer patients.

Fatigue is a common symptom of long COVID. Fatigue can majorly disrupt daily life and be challenging to treat. Herein, we describe the effect of saikokeishito, a Kampo medicine, on fatigue in patients with long COVID.Between October 2020 and March 2023, we prescribed saikokeishito to 22 patients with long COVID in the general medicine outpatient department of our hospital. Among them, seven patients (age: 15-58 years, two females) had fatigue, a previously confirmed diagnosis of COVID-19, and no concomitant use of other Kampo formulas. We compared their condition at the start of saikokeishito administration to that 3 months later. Five patients had a slight fever, and four had inflammatory findings on blood tests. Within 3 months, all patients had a 20% or greater reduction in fatigue on a visual analogue scale. Six patients had a 20% or greater increase in health-related QOL and were able to return to society. On the other hand, one patient required a transition to an alternative medication, and one patient's follow-up was prematurely discontinued. Fatigue after COVID-19 may be improved by saikokeishito, especially for the treatment of patients with slight fever or inflammatory findings.

Purpose: The objective of this study was to investigate whether body fat rate (BFR) and triceps skinfold thickness (TSF) are associated with estimated fentanyl absorption in patients treated with the fentanyl transdermal matrix patch for moderate to severe cancer pain, by measuring the residual content of fentanyl in used matrix patches. Methods: Adult Japanese inpatients experiencing chronic cancer-related pain and receiving treatment for the first time with a transdermal fentanyl matrix patch (Durotep®MT patch) were included in the present study. During the initial application period, BFR was measured using a body fat scale, and TSF was measured by an experienced nurse with an adipometer. One patch was collected from each patient. The residual fentanyl content in used matrix patch was determined by high-performance liquid chromatography. The transdermal fentanyl delivery efficiency was estimated based on the fentanyl content of the used matrix patches. Results: Fifteen adult patients (5 males and 10 females) were included in this study. Nine patches with a release rate of 12.5μg/h and 6 patches with a release rate of 25μg/h were collected. The application site was the chest or upper arm. BFR and TSF both showed a significant positive correlation with delivery efficiency. Conclusion: In malnourished or low-body fat patients receiving DMP, pain intensity should be more carefully monitored, and fentanyl dose adjustment may be required. Additional parameters, such as nutritional status including body fat change, the degree of dry skin, and plasma fentanyl concentration, also require detailed evaluation.

As for the clinical condition to be called “cold stagnating in the liver vessel” (寒滞肝脈kantaikanmyaku),cold invades a liver-­meridian (肝経絡) and causes pain. We report a case of 7-­year-­old boy that reached the difficulty in walking for agreed pain of lower extremities in a liver-­meridian by cold house environment after the diarrhea. There was no abnormality in a blood test and the MR imaging in Western medicine. The treat­ment principle was to warm the meridian and reduce the pain. We chose the infusion of “dankanzen­-based prescription” (暖肝煎加味方) to warm the meridian and to remove the pain. The symptom improved. And the bathing therapy to warm a body relieved pain too. The case report of children of kantaikanmyaku was not found as far as we examined it. However, we believe that such cases are latent in Japan where air conditioners are widely used.
