Background:
The anti-programmed death 1 (PD-1) antibody has led to durable clinical responses in a wide variety of human tumors. We have previously developed the caninized anti-canine PD-1 antibody (ca-4F12-E6) and evaluated its therapeutic properties in dogs with advance-staged oral malignant melanoma (OMM), however, their therapeutic effects on other types of canine tumors remain unclear.
Objective:
The present clinical study was carried out to evaluate the safety profile and clinical efficacy of ca-4F12-E6 in dogs with advanced solid tumors except for OMM.
Methods:
Thirty-eight dogs with non-OMM solid tumors were enrolled prospectively and treated with ca-4F12-E6 at 3 mg/kg every 2 weeks of each 10-week treatment cycle. Adverse events (AEs) and treatment efficacy were graded based on the criteria established by the Veterinary Cooperative Oncology Group.
Results:
One dog was withdrawn, and thirty-seven dogs were evaluated for the safety and efficacy of ca-4F12-E6. Treatment-related AEs of any grade occurred in 13 out of 37 cases (35.1%).Two dogs with sterile nodular panniculitis and one with myasthenia gravis and hypothyroidism were suspected of immune-related AEs. In 30 out of 37 dogs that had target tumor lesions, the overall response and clinical benefit rates were 6.9% and 27.6%, respectively. The median progression-free survival and overall survival time were 70 days and 215 days, respectively.
Conclusions
The present study demonstrated that ca-4F12-E6 was well-tolerated in nonOMM dogs, with a small number of cases showing objective responses. This provides evidence supporting large-scale clinical trials of anti-PD-1 antibody therapy in dogs.

Pericardial pacing wire placement may occasionally result in intravascular or intratracheal wire migration, infective endocarditis, and sepsis; reportedly, the incidence of complications is approximately 0.09 to 0.4%. We report a case of a retained epicardial pacing wire that migrated into the pulmonary artery. A 66-year-old man underwent coronary artery bypass grafting for angina pectoris, with placement of an epicardial pacing wire on the right ventricular epicardium, 6 years prior to presentation. Some resistance was encountered during wire extraction; therefore, it was cut off at the cutaneous level on postoperative day 8. Computed tomography performed 6 years postoperatively revealed migration of the pacing wire into the pulmonary artery, and it was removed using catheter intervention. Surgeons should be aware of complications associated with retained pacing wires in patients in whom epicardial wires are retained after cardiac surgery.

Background This study explored the association of residence, caste, social determinants of health (SDH) of parents, and daily junk food intake with the nutritional status of school children living in different residential areas of a district in Nepal. Methods A survey was conducted from December 2017 to March 2019, including 331 school children aged 6 to 12 years as well as their parents, in the primary village for Japan International Cooperation Agency (JICA) support and the surrounding area in the Machapuchare Administrative Region of Kaski District, Gandagi Province, Nepal. In this study, the body mass index for age z-score (BMIZ), a criterion used by the WHO for assessing malnutrition, was used for determining underweight; BMIZ <−2 SD was defined as underweight. The children’s anthropometric data were measured to assess their nutritional status, and a survey on children’s daily junk food intake and parents' SDH was conducted among parents. The responses were analyzed by logistic regression analysis.Results Of the children who participated in the survey, 31 (9.4%) were underweight. An association between parents’ SDH and children’s underweight was found after adjusting for mothers’ age at marriage, number of siblings, and daily junk food intake, and the results showed that lower caste (OR=0.241, p=0.001), lower education of mothers (OR=3.879, p=0.011) and non-literacy of fathers (OR=2.790, p=0.023) had statistically significant effects on BMIZ.Conclusions In this study, BMIZ, indicating underweight in Nepalese school children, was associated with higher caste and a mother’s level of educational attainment and father’s of non-literacy. To understand the factors influencing children’s health, it is necessary to evaluate sociodemographic parameters of parents as childcare providers, including culture, education, employment, living conditions, and diet, and to conduct surveys that capture data on the SDH of parents from various perspectives.

The aim of this article is to describe the 2017 revised consensus criteria for the clinical diagnosis of dementia with Lewy bodies (DLB) with future directions for the diagnostic criteria. The criteria for the clinical diagnosis of probable and possible DLB were first published as the first consensus report in 1996 and were revised in the third consensus report in 2005. After discussion at the International DLB Conference in Fort Lauderdale, Florida, USA, in 2015, the International DLB Consortium published the fourth consensus report including the revised consensus criteria in 2017. The 2017 revised criteria clearly distinguish between clinical features and diagnostic biomarkers. Significant new information about previously reported aspects of DLB has been incorporated, with increased diagnostic weighting given to rapid eye movement (REM) sleep behavior disorder (RBD) and iodine-123-metaiodobenzylguanidine (MIBG) myocardial scintigraphy. Future directions include the development of the criteria for early diagnosis (prodromal DLB) and the establishment of new biomarkers that directly indicate Lewy-related pathology, including α-synuclein imaging, biopsies of peripheral tissues (skin, etc.) for the demonstration of α-synuclein deposition, and biochemical markers (cerebrospinal fluid/blood), as well as the pathological evaluation of the sensitivity and specificity of the 2017 revised diagnostic criteria. In conclusion, the revised consensus criteria for the clinical diagnosis of DLB were reported with the incorporation of new information about DLB in 2017. Future directions include the development of the criteria for early diagnosis and the establishment of biomarkers directly indicative of Lewy-related pathology.

Background The number of foreign tourists visiting Japan has increased to about 30 million people per year. 1.5% of them were injured or became sick during their travelin Japan and had to undergo medical treatment. Among the foreign tourists, 27% were not covered by travel health insurance.Case A 40-year-old man from Southeast Asia who was visiting his relative in Japan experienced sudden hemiparesis and was diagnosed with cerebral infarction. During the initial treatment, it was found that the patient did not have health insurance and the relatives could not afford to pay the treatment costs. No other source of financial support was available to him During our consultations with the patient and his relatives about the medical treatment including medical expenses, he continued to be treated as an outpatient and it was aimed at an early return to his home country.Discussion Foreigners, who are not covered under travel health insurance, could fall ill or sustain an injury during their stay in Japan. Appropriate medical care should be provided regardless of their ability to pay. However, a situation that could lead them to incur huge medical expenses from availing medical care should be avoided. For medical consultations of non-insured foreigners, it is better to consult the available systems and pay attention about feasible medical expenses. There is a need for a long-term vision of medical care to make a smooth transition from medical treatment in Japan to treatment in their home country.Conclusion Although medical institutions can offer only a limited response, it is necessary to accumulate case examples from across the nation and prepare specific countermeasures and counselors.

OBJECTIVES: The purpose of this study was to investigate the influences of interruption and reinitiation of monthly minodronate therapy on the bone mineral density (BMD) and bone metabolism markers in postmenopausal women with osteoporosis. METHODS: Study patients were included if they had been administered monthly minodronate therapy for ≥6 months, interrupted the therapy, and reinitiated the therapy for ≥12 months. The BMD and bone metabolism markers were assessed at 4 time points: initiation, interruption, reinitiation and 1 year after reinitiation of therapy. RESULTS: A total of 23 patients were enrolled. The mean monthly minodronate treatment period was 23.8 ± 12.9 months following a mean interruption period of 11.9 ± 5.4 months. Once increased by monthly minodronate treatment for 2 years on average, the BMD of lumbar spine and radius did not significantly decrease even after an interruption for 1 year on average. However, the BMD of the femoral neck did decrease after interruption. The BMD of the lumbar spine and radius increased further after 1 year of monthly minodronate retreatment. The BMD of the femoral neck did not change. Once decreased after the treatment for an average of 2 years followed by an interruption for 1 year, bone metabolism markers increased gradually but did not recover to baseline levels. A potent suppressive effect on bone resorption was noted. The change rate was greater for the bone formation marker procollagen 1 N-terminal propeptide. CONCLUSIONS: Monthly minodronate treatment increases BMD and reduces bone metabolism markers. The effect lessens after treatment interruptions, and can be restored by retreatment.

A 71-year-old man with Behçet's disease was admitted to our hospital for treatment of a thoracic aortic aneurysm. On admission, there was marked inflammatory response, but blood culture was negative and there was no significant accumulation of gallium scintigraphy. The aorta was shaggy and there were two aneurysms in the descending aorta. We performed endovascular aortic repair for this aneurysm in consideration of the inflammatory aortic aneurysm. After treatment, the patient had paraparesis, however he underwent physical rehabilitation to regain function. He was followed up for 1 year and remains in good clinical condition without anastomotic aneurysm, dilatation or aneurysm at another site.

Introduction: TVS mud index1) is a tensiometric marker for quality and maturation process control of Italian Euganean Thermal Muds (ETM) which sensitivity defined on objective basis their quality and maturation degree. Objectives: The goal was to assess the maturation process of Biofango by TVS mud index (Sanraku-en spas centre, Japan and Osservatorio Termale Permanente-OTP, Italy), and its organic compounds by TOC analyses (University of Padova, Italy). Materials and Methods: Biofango was prepared using KomatsuClay, MotoyamaClay, WakuraDiatomite and KasaokaBentonite giving K02 (Bentonite 1.25, Kaolinite 1.5, Diatomite 0.25) and A01 (KasaokaBentonite 1.25, Kaolinite 0.5, Diatomite 0.25). Final Biofango BFM+0%Dolomite, MAT1+10%Dolomite, MAT2+18%Dolomite, and MAT3+35%Dolomite were analyzed by TOC (Perkin-Elmer-2400) and DSA10-Krüss employing (a) PFPE, Fomblin HC/OH-1000, diiodomethane, glycerine as liquid tests and (b) Owens-Wendt mathematical model for conversion of contact angles in surface energy parameters2). Results: The behaviour of C(%) in MAT1, MAT2, and MAT3 during maturation process (20°C) showed respectively (a) MAT1t0h=1.26%, MAT1t216h=0.91%, MAT1t360=1.08%, MAT1t576h=1.23%, MAT1t720h=0.98%, (b) MAT2t0h=2.36%, MAT2t216h=1.80%, MAT2t360=1.49%, MAT2t576h=1.86%, MAT2t720h=1.68%, (c) MAT3t0h=3.29%, MAT3t216h=2.71%, MAT3t360=2.57%, MAT3t576h=2.6%, MAT3t720h=2.7%. C% decrease demonstrating the influence of Dolomite in Biofango mixtures. Dispersed energy components (DC) of MAT1, MAT2, and MAT3 showed respectively (a) MAT1t0h=3.0mN/m, MAT1t216h=3.1mN/m, MAT1t360=2.9mN/m, MAT1t576h=3.8mN/m, MAT1t720h=2.5mN/m, (b) MAT2t0h=2.1mN/m, MAT2t216h=2.2mN/m, MAT2t360=3.1mN/m, MAT2t576h=3.7mN/m, MAT2t720h=2.6mN/m, (c)MAT3t0h=2.0mN/m, MAT3t216h=2.6mN/m, MAT3t360=2.6mN/m, MAT3t576h=2.9mN/m, MAT2t720h=3.0mN/m. On the other side TVS mud index showed respectively (a) MAT1t0h=68.7mN/m, MAT1t216h=70.26mN/m, MAT1t360=71.78mN/m, MAT1t576h=64.69mN/m, MAT1t720h=71.84mN/m, (b) MAT2t0h=74.06mN/m, MAT2t216h=71.69mN/m, MAT2t360= 70.36mN/m, MAT2t576h=65.83mN/m, MAT2t720h=71.23mN/m, (c) MAT3t0h=75.9mN/m, MAT3t216h=73.05mN/m, MAT3t360=73.34mN/m, MAT3t576h=68.52mN/m, MAT3t720h=68.66mN/m proportionally inverse with DC behaviour. MAT3 with highest content in Dolomite demonstrated great capability to uptake DC during maturation process with consequently decrease of TVS mud index levels accordingly with TOC result. Conclusions: Tensiometric investigations of Biofango underlined the links between chemical and surface energy data. The high sensitivity of TVS mud index consented to follow directly in a non invasive way the structural-surface changes in Biofango mixtures occurred during maturation process opening at new perspective for their control.

Purpose: To report a case of successful treatment using gabapentin against hot flashes due to LH-RH agonist in a patient with advanced prostate cancer. Case summary: A male patient in his seventies with advanced prostate cancer had hot flashes due to LH-RH agonist therapy. The patient began to notice hot flashes within a few months after starting hormone treatment. Oral gabapentin was administered at a starting dose of 400mg/day and was gradually escalated to 1,200mg/day. Within 7 days of administration, the patient achieved a partial improvement of his symptoms. After 17 days of gabapentin therapy, the hot flashes significantly improved. While the patient was taking a maintenance dose of 1,200mg/day, he remained to be asymptomatic. Conclusion: There are only a few reports (none in Japan) that show effectiveness of gabapentin against hot flashes due to hormone treatment in male patients with prostate cancer. Although the mechanism of the hot flash-relieving effect of gabapentin is not fully understood, this case report indicates that gabapentin may help treating patients suffering from intractable hot flashes.

This paper proposes a method for evaluating and scoring the activities of rehabilitation service users in order to pinpoint the problems with the health service of this kind and set the adequate targets for each user. Sincs the Nursing Care Insurance System was introduced in Japan in 2000, it has been argued that home-visit rehabilitation services should be excluded from home-nursing care services. However, the methods of certifing that nursing care is required are not fully established yet for setting the rehabilitation targets for service users. As things stand, it is recommended that such a method as the Functional Independence Measure (FIM) or the Barthel Index (BI) should be utilized. However, these methods only evaluate “performing activities” (the activities that a user usually performs). In order to set the users' targets, we thought it necessary to establish a method for evaluating “possible activities” (the activities that a user is able to perform at his/her full capacity). We have established a method called Functional Scoring (FS) which evaluates and scores the both performing and possible activities based on the same evaluation items. We conducted experimental evaluations on the home-visit rehabilitation users for one year from October 2005 to September 2006. When the first evaluations in 2005 were compared with the second evaluations in 2006, the total score of the performing activities significantly increased from 44.1±13.7 to 47.8±14.2 (P<0.05). Although the total score of the possible activities did not significantly increase, it demonstrated an upward trend from 49.6±13.2 to 51.6±13.5. The result suggests that our method is useful for distinguishing between the performing and possible activities. The proposed method enables us to adequately recognize the problems each user has, and to set the rehabilitation target for each user, which can be shared between the user, care personnel, and care service provider.
