It is very important to cooperate with interprofessional personnel is in order to establish the community-based integrated care system, but this is very difficult. We have held comprehensive consultation services regarding medical, welfare, and legal problems to support the community.Objectives: This study aimed to identify the associations between background factors (such as medical conditions, intractable diseases, welfare problems, disabilities, economic difficulties, legal problems, elderly adults, children, and foreign persons) and difficult cases to provide more thorough consultation services.Patients and Methods: A survey was conducted on people who participated in comprehensive consultation services on medical, welfare, and legal issues related to medical care, welfare, and legal matters held from April 2021 to March 2024. We analyzed risk factors that may be difficult to resolve using multivariate logistic regression.Results: Multivariate analysis showed that the factor of “economic difficulty” was significantly more difficult to solve.Conclusion: When treating patients, doctors must consider the possibility of multiple underlying issues. It is advisable for doctors to be aware of the need to consult with social workers and legal professionals when necessary.

Objectives: Diagnosis and treatment of osteoporosis are instrumental in obtaining good outcomes of hip surgery.Measuring bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) is the gold standard for diagnosing osteoporosis. However, due to limited access to DXA, there is a need for a screening tool to identify patients at a higher risk of osteoporosis. We analyzed the potential utility of the Osteoporosis Self-assessment Tool for Asians (OSTA) as a screening tool for osteoporosis. Methods: A total of 1378 female patients who underwent hip surgery at 8 institutions were analyzed. For each patient, the BMD of the proximal femoral region was measured by DXA (DXA-BMD), and the correlation with OSTA score (as a continuous variable) was assessed. Receiver operating characteristic (ROC) curve analysis was performed to assess the ability of OSTA score to predict osteoporosis. Lastly, the OSTA score was truncated to yield an integer (OSTA index) to clarify the percentage of patients with osteoporosis for each index. Results: DXA-BMD showed a strong correlation with OSTA (r = 0.683; P < 0.001). On ROC curve analysis, the optimal OSTA score cut-off value of − 5.4 was associated with 73.8% sensitivity and 80.9% specificity for diagnosis of osteoporosis (area under the curve: 0.842). A decrease in the OSTA index by 1 unit was associated with a 7.3% increase in the probability of osteoporosis. Conclusions OSTA is a potentially useful tool for screening osteoporosis in patients undergoing hip surgery. Our findings may help identify high-risk patients who require further investigation using DXA.

Based on the social context of an aging society and surveys conducted since 2020, the need for comprehensive perspectives and approaches that consider patients'psychosocial background and a cross-organ perspective has been identified. As a result, a new quality and ability, namely comprehensive attitudes toward patients, has been established as part of the core curriculum for medical education in FY2022. Specific learning objectives include "holistic perspectives and approaches," "community perspectives and approaches," "life perspectives and approaches," and "social perspectives and approaches". An educational design that draws on multiple learning theories to enable reflection on one's own way of being has been proposed to integrate abstract and concrete, conceptual and experiential, and self and others perspectives. It is expected that this medical education will lead to improvement in the well-being of individuals, families, and communities.

Objective: In Japan, only a few reports of the Ross procedure in neonates and infants have been published. The objective of this study was to evaluate the outcome of patients undergoing a Ross procedure before the age of one year, and to review the validity of opting for this procedure at this age. Methods: The records of 13 infants (including three neonates) undergoing a Ross procedure between December 1996 and June 2017 were reviewed. Major outcomes studied included graft-associated morbidity, autograft function, and the need for reoperation. Results: The median age at the time of Ross procedure was 166 days, and median weight was 5.7 kg. Primary diagnoses were aortic stenosis in 10 cases and aortic insufficiency in three. Nine cases required emergent Ross procedure due to left ventricular dysfunction refractory to medication, requirement of mechanical ventilation or intravenous inotropic drugs. Concomitant procedures included three aortic coarctation repairs, two annular enlargement procedures with a Konno incision and one each of aortic and mitral annuloplasty. The mean cross-clamp time was 131 min and the mean extracorporeal circulation time was 178 min. Two cases required extracorporeal membrane oxygenation. Seven underwent delayed sternal closure and four required postoperative peritoneal dialysis. The median duration of mechanical ventilation was five days and the median length of intensive care unit stay was seven days. Survival was 100% at a median follow-up of 9.9 years. The diameter of the aortic annulus mostly stayed within normal limits, although sinus of Valsalva's enlargement beyond normal value was noted in some cases. Trans-aortic valve pressure gradient was less than 20 mmHg and aortic insufficiency was less than mild in all cases, thus requiring no reintervention for the valve. Two cases required coronary arterial bypass and release of the subaortic stenosis. Freedom from reoperation for the left heart was 100% at one year, and 81.5% at five years and 10 years. Ten cases required reoperation for the right heart, and freedom from reoperation was 84.6% at one year, 29.7% at five years and 9.9% at 10 years. Conclusion: Durability of the pulmonary autograft was excellent. The Ross procedure can be an effective treatment strategy for severe aortic valve diseases in neonates and infants.

  We examined how difficult it would be for the elderly living in mountainous areas to go to the nearest hospital using a Voronoi tessellation representing the mathematical concept of neighborhood. We defined the index of the nursing-care capacity for the elderly as the ratio of the number of caregivers to the number of the elderly receiving nursing-care.
  The mean age of those who drive to the hospital by themselves worked out at 70±9.8 years. Meanwhile, that of those who go to the hospital by bus or taken to hospital in a car driven by a family member came to 80±7.0years. The latter was significantly older than the former.
  The areas of the Voronoi tessellation generated by patients' places of residence were divided into three groups according to the size. The plots of these three groups of the the places of residence on the map had a three-layer and doughnut-like structure, i. e., inner-, middle-, and outer-layer.
  The index of the nursing-care capacity in 2008 was less than 1.0 for the patients under 80 years of age. This means that when those who were at the age of 50 in 2008 become old and need nursing-care, access to the hospital will become harder to them than at present. For those who are over 80 years of age and live in the outer layer that is far away from arterial road, it will be almost impossible.
  These findings suggest that outpatient care with transportation assistance by a family member at present should be reconsidered because of the future lack of care personnel. It would also be necessary to consider the welfare of older people from the geographical point of view in order to manage the problems concerning the various physical and sociological difficulties of the elderly.

Installation of toilet is an important issue for improvement of sanitary condition all over the developing countries. A Japanese NGO is trying to improve toilets which are planned to fit the rural environment in a village of an ethnic minority, the Hmong people, in northern Thailand. The toilet installed in a nursery school can produce methane gas from septic tank for cooking of lunch. The overflowed water from septic tank is able to be used for fertilizer in a kitchen garden. The concept of this toilet is the minimization of the release of carbon dioxide in the human life by the ecological use of human faces and urine that consume much energy for appropriate treatment in developed countries. The system will be developed to be one of an ideal model of the recycle system of natural resource. This project of innovating toilet is useful for the educational materials of the model of sustainable development for not only for under developing countries but also for developed countries in that it reminds us the traditional culture of utilization of human feces in Japan.

Edaravone is an agent developed as a free radical scavenger, and is useful in functional recovery of the brain after cerebral infarction. However, to the best of our knowledge no experimental studies have been made regarding the effect of edaravone on cerebral protection during aortic arch surgery. We investigated the pharmacological effect of edaravone experimentally, through selective cerebral perfusion under deep hypothermia. Twelve adult dogs (body weight 14.8±2.0 kg) were used, and selective cerebral perfusion was performed under hypothermic circulatory arrest of 20°C for 120 min at 5 mg/kg/min, which was half the usual flow volume of cerebral perfusion. Group E (n=6) received 3 mg/kg edaravone for 30 min at the start of both selective cerebral perfusion and rewarming of the body, while Group C (n=6) received no drugs. Somatosensory evoked potential (SEP) was measured, and so were blood pressure, body temperature, pH level, oxygen partial pressure, and blood flow in the cerebral tissue. Histopathological investigations were also performed. In Group E, complete SEP recovery was observed in all dogs, while in Group C, complete SEP recovery was observed in only 2 dogs (33%) (p=0.014). A statistically significant difference was also observed in cerebral tissue pressure (p=0.014), but not in pH level, oxygen partial pressure, or cerebral tissue blood flow. On histopathological investigation, Group C demonstrated reduced staining of Nissl granules in neurons of the cerebral cortex, and many of them presented the appearance of acute circulatory impairment while Group E demonstrated no reduction in staining of Nissl granules. In the present experimental study of selective cerebral perfusion under deep hypothermia below the safety threshold flow, edaravone was effective in cerebral protection.

A 22-year-old woman had been treated with a Ross operation for aortic root aneurysm and aortic regurgitation 10 years previously. In the initial Ross operation, a handmade tri-leaflet conduit was used for the right ventricle outflow tract (RVOT) reconstruction. The conduit was prepared preoperatively, by sewing a folded 0.1 mm expanded polytetrafluoroethylene (ePTFE) membrane onto the luminal cavity of the 24 mm woven double velour vascular graft, thereby creating a tri-leaflet valve. During ambulatory follow up after discharge, dilation of the pulmonary autograft had been observed, and its maximal diameter reached 60 mm. Furthermore, preoperative a pressure study revealed a 25 mmHg pressure gradient between the right ventricle and the pulmonary artery. At the time of reoperation, we performed an aortic root replacement combined with RVOT conduit replacement. A 24-mm woven double velour vascular graft integrating a 21-mm On-X mechanical prosthesis was used for aortic root replacement. A handmade ePTFE tri-leaflet conduit, 26 mm in size, was used to replace the previous RVOT conduit. The operation was successful, and the postoperative course was uneventful. The explanted conduit was sent for microscopic examination, which revealed that the graft was covered by a fibrocollagenous membrane. On the contrary, no surface membrane was found on the ePTFE valve. Moreover the microscopic examination showed cystic medionecrosis of the pulmonary autograft. Both dilatation of the pulmonary autograft and RVOT conduit failure were successfully treated at the second operation. However this young patient will require follow-up of the mechanical prosthesis and RVOT conduit for the rest of her life.

We performed combination therapy with modified oxaliplatin/l-LV/5-FU (mFOLFOX) in a patient with recurrent colorectal cancer who had peritonitis carcinomatosis. In this patient, mFOLFOX therapy resulted in disappearance of ascites and a decrease in carbohydrate antigen 19-9 (CA19-9), and improved quality of life (QOL) of the patient. This 62-year-old man was diagnosed with ascending colon cancer and metastatic cancer of the liver. Right hemicolectomy and right hepatic lobectomy were performed. We had started to treat with TS-1 in ambulatory care, however, he had peritonitis carcinomatosis with massive ascite reservoir on CT and peritoneal dissemination after a half year postoperatively. Furthermore, his ECOG Performance Status (PS) was rated as level 3. Therefore, we performed puncture of ascites and palliative mFOLFOX6 therapy. After ten courses, ascites and abdominal induration had disappeared and PS recovered to level 1. At present, CPT-11/l-LV/5-FU (FOLFIRI) are being administered for peripheral neuropathy and metastatic tumor associated with mFOLFOX6. The patient is spending his daily life satisfactory after FOLFIRI without abdominal swelling or ascites, and thus mFOLFOX6 may be an option for palliative therapy against massive ascites in patients with advanced colorectal cancer. The usefulness of palliative mFOLFOX6 therapy for patients with massive ascites should be evaluated in a well-designed clinical trial.Palliat Care Res 2008; 3(2): 316-320
