Prognostic factors in patients in the terminal phase of haematological malignancies who are receiving home medical care.

Although there are many prognostic models for patients in the terminal phase of solid tumours, a reliable prognostic scoring system in patients in the terminal phase of haematological malignancies (HM) has not been established. We retrospectively evaluated 180 patients in the terminal phase of HM who were receiving home medical care (HMC). Multivariate analyses revealed that clinician's estimate, consciousness, loss of appetite, dyspnoea, neutrophil count, lymphocyte count, and lactate dehydrogenase were associated with overall survival (OS). Based on this result, we developed a novel prognostic scoring system, the Japan palliative haematological oncology prognostic estimates, in which four risk groups were shown to clearly differ in survival (p < 0.001): a low-risk group (n = 41, median OS of 434 days), an intermediate-low-risk group (n = 80, median OS of 112 days), an intermediate-high-risk group (n = 38, median OS of 31.5 days), and a high-risk group (n = 21, median OS of 10 days). This is the first investigation of prognostic factors that influence the OS of patients in the terminal phase of HM who are receiving HMC. Providing patients with reliable information about their prognosis is important for them to consider how to spend their remaining life.

Management system of home transfusion in Japan: A nationwide survey in 2019.

BACKGROUND AND OBJECTIVES: In Japan, there are various opinions on the pros and cons of home transfusion because of safety concerns. We hence aimed to elucidate the safety and availability of home transfusion in Japan, which has not been clarified to date. MATERIALS AND METHODS: Clinics throughout Japan that provide home care and have experience in performing blood transfusions were surveyed. The analysis period was February to December 2019. Basic information about the clinics, their collaboration system with core hospitals, storage method of red blood cells (RBCs) and the system for the management of patient information regarding transfusion reactions were investigated. RESULTS: Detailed information was obtained regarding the implementation of home transfusions by 51 clinics. The proportion of home care clinics performing home transfusions was 17.6%, and they were more frequently performed in urban regions. Approximately half of the clinics collaborated with a core hospital for emergency responses to transfusion reactions. At 84% of the clinics, RBC units were stored in refrigerators that were not exclusively allocated to blood storage. Nurses and family members were involved as patient attendants in 83% and 77% of the home transfusions, respectively. No serious transfusion reactions were reported among the 150 patients in 2019, nor the 623 patients up to 2018. CONCLUSION: From data on its availability and safety, home transfusions are considered to be in the developing phase in Japan. Increased cooperation between hospitals and clinics is crucial towards improving the home transfusion system in Japan in the future.

Home transfusions are implemented using diverse approaches in Japan.

BACKGROUND AND OBJECTIVES: Japan's ageing society has increased the need for home healthcare, including home transfusions. We hence aimed to elucidate the purpose and utilization of home transfusions in Japan, which has not been clarified to date. MATERIALS AND METHODS: Clinics throughout Japan that provide home care and have experience in performing blood transfusions were surveyed. The study period was February to December 2019, and information of patients receiving home red blood cell transfusions, including patient background, pre-transfusion laboratory data and the purpose of the transfusions, was collected. RESULTS: Haematological malignancies and solid tumours accounted for 70% of the patients' underlying diseases, with the former being significantly more common in urban areas. Regarding the purpose of the home transfusions, haematologists focused on symptom improvement, whereas gastroenterology surgeons focused on life support. Furthermore, maintenance of life was more likely to be the aim in the group of patients with the lowest level of activities of daily living. The main items that were significantly associated with a low haemoglobin level before transfusion included age ≥90 years and a gastroenterologist being the physician in charge. CONCLUSION: Home transfusions were found to be performed in a restrictive and diverse manner in Japan. Life support is the second most common purpose of home transfusion in Japan, and optimizing effective home transfusion remains a challenge.

[A Survey on Home Care Needs of Patients with Hematological Diseases].

Home care for patients with hematological diseases is often difficult to coordinate due to the challenges associated with continuous provision of supportive therapies, such as blood transfusions. On the other hand, home care needs of patients with hematological diseases are not clear. In this study, we conducted a questionnaire survey of patients with hematological diseases under home care. Responses were obtained from 605 patients with hematological diseases. Regarding home care, their primary expectation was a reduction in the physical burden caused by hospital visits, while their primary concern was emergency care due to a sudden change in their conditions. More than 90% of the patients stated that they wished to be seen by hematology specialists. In terms of blood transfusions, 53.5% wished to continue receiving a red blood cell transfusion and 53.9% a platelet transfusion at home. Furthermore, 70.9% of the patients stated that palliative chemotherapy was also needed in home care. With respect to emergency care, the highest percentage of patients(56.5%)wanted their home care doctors to treat them first and, if needed, contact their attending doctors at the hospital. This suggests the possibility that "the two-attending doctor system,"a concept that has gained importance in recent years, may also be effective in home care for hematological diseases.

Mini grasping basket forceps for endobronchial foreign body removal in pediatric patients.

BACKGROUND: Appropriate device selection is crucial for endobronchial foreign body removal using a bronchoscope. In pediatric patients, bronchoscopy requires the use of a thin device due to the narrow access to the airway, limiting the range of useful endobronchial devices. We herein review our experience in endobronchial foreign body removal with a focus on the type of bronchoscope and the instruments used in comparison with the literature, and investigate the utility of mini grasping basket forceps (FG-55D, Olympus® ; and Zero Tip™ , Airway Retrieval Basket, Boston Scientific). METHODS: Between April 2008 and April 2016, foreign bodies were removed from the airway of 12 pediatric patients by bronchoscopy. These cases are reviewed in this study. The clinical presentation, location and characteristics of the foreign bodies, and the type of bronchoscope and instruments used were analyzed. RESULTS: A consecutive series of 12 pediatric patients was retrospectively reviewed, and the therapeutic characteristics investigated. Nuts were the most frequently observed foreign body. Seven of the 12 pediatric patients required an ultrathin bronchoscope (diameter, 2.8 mm) for foreign body removal. Only one patient required a rigid scope in addition to flexible bronchoscopy. The most frequently used instrument was a mini grasping basket forceps (n = 7; 58%), which was used with a 1.2 mm instrument channel (n = 4; 33%). CONCLUSIONS: The use of a mini grasping basket forceps in combination with an ultrathin flexible bronchoscope was useful for removing smooth, soft materials such as a nuts or beans in pediatric cases.

[Relapsed/refractory multiple myeloma with CD138 shedding and formation of extramedullary disease in the common bile duct region presenting as obstructive jaundice].

A 56-year-old man was diagnosed with immunoglobulin (Ig) A-κ multiple myeloma in July 2007. After three courses of vincristine, adriamycin, and dexamethasone (VAD) chemotherapy, autologous peripheral blood stem cell transplantation was performed and achieved a very good partial response. In February 2010, an increase in the M-protein concentration and plasmacytoma in the L3/4 lumbar vertebrae were observed, and radiation treatment was performed. This was followed by administrations of bortezomib, lenalidomide, and thalidomide, none of which achieved a good response. In November 2011, the patient presented with obstructive jaundice, and imaging tests revealed tumorous lesions in the lower bile duct region and bilateral kidneys. Plasmacytoma was diagnosed from biopsy of the right renal mass. Radiotherapy to the common bile duct tumor resulted in jaundice amelioration, but the patient died despite subsequent treatment efforts. Autopsy revealed multiple extramedullary lesions in the abdominal cavity and in the region around the common bile duct. CD138 shedding was observed in the myeloma cells. We include a discussion of the literature on CD138 shedding and 38 reports of obstructive jaundice associated with extramedullary disease.

[Our Experience of Providing Home End-of-Life Care for a Child with a Brain Tumor - Overview of Issues Including Environmental Adjustment and Family Care].

INTRODUCTION: We provided home end-of-life care to a child with a brain tumor. As cases of children with malignancies who receive such care have rarely been described in Japan, we report our experience with this patient. CASE REPORT: An 11-year-old previously healthy boy was found to have a brainstem glioma in December X. The tumor was reduced by radiotherapy and chemotherapy, but relapse was noted in August X plus 1. Best supportive care alone was selected for this patient. Before the initiation of home care, we consulted a designated hospital for pediatric cancer treatment in the area and requested a case- worker from the child/home section in his resident area. As the patient was too young for long-term care insurance, we immediately applied for a physical disability certificate to augment welfare support. After the initiation of home care, swallowing function diminished markedly, but we provided guidance on dietary contents and suction, allowing continued oral ingestion by prioritizing his and his family's wishes. In January X plus 2 of the following year, his respiratory condition worsened after the development of aspiration pneumonitis, and he died at home. SUMMARY: We advocate the establishment of a regional network so that children with brain tumors can receive end-of-life care at home.

[A patient with Creutzfeldt-Jakob disease supported by home medical care from the stage of disease progression to death through hospital-clinic cooperation and medical-welfare cooperation].

The patient was a 63-year-old woman who presented with slowness of speech after cerebral infarction. Diffusion-weighted MR images and investigations of cerebrospinal fluid showed abnormal values, and the patient was diagnosed as having sporadic Creutzfeldt-Jakob disease(CJD). This is an intractable disease and affects one in one million people; it progresses relatively rapidly, eventually resulting in death. For procedures such as intravenous fluid replacement and the treatment of pressure sores, we require thorough hand washing, eye protection, and disposal of gloves and dressings by incineration. It is desirable for patients to spend the limited amount of time available to them peacefully at home with their family. Visiting physicians and nurses need to take the initiative in sharing information obtained from the CJD infection control guidelines and core hospitals with welfare personnel such as caregivers, in order to provide correct information on all aspects of patient care and the management of this disease in the home environment. Excellent supportive care was provided for the patient at home, and she passed away with her family by her side.

[Rapid improvement of fluid retention with lenalidomide plus low-dose dexamethasone for POEMS syndrome relapsed after autologous peripheral blood stem cell transplantation].

We report a 53-year-old male with POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome who relapsed after autologous peripheral stem cell transplantation (ASCT), but responded extremely well to lenalidomide (LEN) plus low dose dexamethasone (Ld) therapy. The patient had been diagnosed with POEMS syndrome in November 2006, and underwent ASCT in February 2007. In July 2011, he developed respiratory distress, generalized edema, and massive bilateral pleural effusion. Plasma vascular endothelial growth factor (VEGF) and M protein were increased, strongly indicating a relapse. Ld therapy was remarkably effective for these symptoms, resulting in complete remission with M-protein becoming undetectable by immunofixation. Since completing 11 courses of therapy with an every 4 weeks regimen, he has remained in clinical remission. The patient's activities of daily living have also markedly improved from total physical incapacity to being able to stand with slight assistance. LEN is associated with a lower incidence of peripheral neuropathy than other new drugs. Although LEN has occasionally been given to patients with POEMS syndrome in recent years, there are still few reports on its use for patients with recurrent disease after ASCT. Our successful management of this patient suggests that Ld therapy is not only relatively safe but also a promising option for POEMS syndrome relapsing after ASCT.

Postoperative hormonal therapies reduce the recurrence of thoracic endometriosis-related pneumothorax.

OBJECTIVES: Thoracic endometriosis-related pneumothorax (TERP) frequently recurs even after surgery. Meanwhile, postoperative hormonal therapies (HTx) are believed to be effective for pelvic endometriosis. Therefore, we evaluated the relationship between postoperative TERP recurrence and postoperative HTx in a retrospective observational study. METHODS: We retrospectively reviewed the data of patients with TERP who underwent the first video-assisted thoracoscopic surgery between January 2011 and February 2022. RESULTS: Of the 248 patients eligible for this study, 67 (27.0%) experienced postoperative TERP recurrence. Postoperative HTx were administered to 70 patients (28.2%). Dienogest was the most frequently administered drug, given to 56.7% of patients. Following univariable analysis, postoperative hormonal therapies was closely related to reduce postoperative recurrence (P = 0.003). Likewise, the multivariable analysis revealed postoperative hormonal therapies were significantly associated with the risk reduction of recurrence (hazard ratio 0.28, P < 0.001). CONCLUSIONS: Postoperative HTx reduced TERP recurrence. We hypothesize that HTx may control residual endometrial tissues to avoid TERP if pleural endometrial tissues are resected as much as possible.

Postoperative pain and quality of life after lung cancer surgery: a prospective observational study.

BACKGROUND: We aimed to identify the factors associated with postoperative pain, quality of life, and development of chronic pain after lung cancer surgery, including pain sensation threshold, fentanyl sensitivity, and surgical procedures. METHODS: We conducted a single-center prospective observational study involving lung cancer patients. Brief pain inventory, including nine items concerning pain and quality of life, was investigated at 1 week, 1 month, and 3 months postoperatively. Pain sensation threshold and fentanyl sensitivity were assessed preoperatively. RESULTS: Of the 146 patients who were enrolled, 100 who met our criteria were analyzed. Thoracoscopic surgery was performed in 42 patients and minimally invasive thoracotomy in 58 patients. Pain sensation threshold and fentanyl sensitivity were normally distributed among the patients and were not significantly associated with brief pain inventory scores at each postoperative time-point. The average pain score 1 week after the operation was significantly higher in the thoracotomy group than in the thoracoscopic surgery group (P<0.050). The worst pain scores did not differ between the groups at all the examination periods. Pain sensation threshold, fentanyl sensitivity, and surgical procedures were not related to the incidence of post-thoracotomy pain syndrome. CONCLUSIONS: Individual pain sensation threshold and fentanyl sensitivity were not associated with subjective postoperative pain score, quality of life score, or development of post-thoracotomy pain syndrome.

Syntheses of Chalcone-Type Chlorophyll Derivatives Possessing a Bacteriochlorin, Chlorin or Porphyrin π-System and Their Optical Properties.

C3-(Trans-2-arylethenyl)carbonylated chlorophyll derivatives possessing a bacteriochlorin or chlorin π-system were synthesized by cross-aldol (Claisen-Schmidt) condensation of methyl pyrobacteriopheophorbide-a or 3-acetyl-3-devinyl-pyropheophorbide-a bearing the C3-acetyl group with p-(un)substituted benzaldehydes under basic conditions. The corresponding porphyrin-type chlorophyll derivatives were prepared by the oxidation (17,18-didehydrogenation) of the chlorin-type. Their Qy absorption and fluorescence emission maxima in dichloromethane correlated well with Hammett substituent constants of the p-substituents. Several electron-withdrawing p-substituents suppressed the emission due to photoinduced electron transfer quenching in a molecule. The substitution sensitivities for their maxima and fluorescence quantum yields decreased in the order of bacteriochlorin-, chlorin- and porphyrin-type derivatives.

Characteristics of palliative home care for patients with hematological tumors compared to those of patients with solid tumors.

Home care medicine is a platform for providing supportive care for end-stage cancers. However, for undefined reasons, patients with hematological tumors (HTs) often fail to receive opportunities for home care. We, therefore, sought to delineate the clinical differences between solid tumors (STs) and HTs and to determine whether home care is effective for patients with HTs, as well as those with STs. We retrospectively analyzed the treatments, prognosis, and places of death of patients with STs (n = 99) and HTs (n = 20) who received palliative home care in our clinic and subsequently died between May 2016 and May 2018. Patients with HTs commonly required intravenous antibiotics, platelet transfusion, and red blood cell transfusion, while patients with STs tended to more frequently require the use of opioids. Importantly, there were no significant differences between the cohorts with respect to survival time and frequency of emergent visits to patients after their referral to us. Furthermore, most patients in both groups died at home. More than 50% of patients were not admitted to hospitals during our follow-up. Collectively, while therapeutic approaches sometimes differ, this study provides clinical evidence that palliative home care can be feasible even for patients with HTs.
