RESUMEN
Background Thiamine deficiency (TD) is an important public health problem in nutrition, occurring in 2-6% of the population in Europe and the US, whereas thiamine levels are reported to be significantly reduced by 36.6-40% in some populations of East Asia. However, there is little information available at present, regarding factors such as age, despite the continued aging of society. Further, studies such as those mentioned above have not yet been undertaken in Japan, the country in which population aging is most advanced. Objective To investigate TD in the Japanese community-dwelling individuals who are independently ambulatory. Methods We undertook an examination of TD in blood samples obtained from 270 citizens in a provincial town, aged 25-97 years, who were able to walk to the venue and provide informed consent for inclusion in this research and of whom 8.9% had a history of cancer. We summarized the demographic characteristics of the subjects. The whole-blood thiamine concentrations were measured using the high-performance liquid chromatography method. A value of 21.3 ng/ml or less was taken as low and a borderline value was set as less than 28 ng/ml. Results The mean (±SD) whole blood thiamine concentration was 47.6 ± 8.7 ng/ml. No TD was observed to exist participating in this study, with no subjects even showing show borderline values. Further, there was no significant difference in thiamine level between those aged 65 or older and those aged less than 65. Conclusions No cases of TD were observed among the subjects in this study, nor was the concentration of thiamine found to be related to age. It is possible that the frequency of TD might be very low in citizens who have a certain level of activity. In the future, it is necessary to expand the prevalence of TD to a wider range of subjects.
RESUMEN
Background: Although thiamine deficiency (TD) can lead to Wernicke encephalopathy, the characteristics associated with TD in the elderly have not yet been clarified. We sought to clarify the frequency of TD among an institutionalized elderly population with a controlled dietary intake and to identify possible factors related to TD. Method: We undertook a cross-sectional study of residents in three nursing homes for the elderly as of June 2020. Blood thiamine concentrations were measured using a high-performance liquid chromatography method, with TD defined as a concentration of <21.3 ng/mL. Basic data (age, sex, height, weight, and BMI), dietary intake for the previous 3 weeks, degree of care (DOC), degree of independence in daily life for elderly with dementia (DIDLED), and comorbidities were analyzed using descriptive statistical methods. Results: The mean age (±SD) was 86.9 years (±8.29), with 84 residents (70.0%) being female. The DIDLED varied from total independence to long-term care level 5 (full assistance), with 89.2% suffering dementia. The mean whole blood thiamine value was 36.18 (±17.58) ng/ml, with TD confirmed in 7 (5.8%) of the 120 residents. All TD patients suffered from dementia. No TD was observed in patients with a near-normal food intake, and no related factors were observed among the other items. Conclusion: Reduced food intake may at increase the risk of TD and symptoms of TD may be overlooked in those displaying symptoms of dementia; thus, it is important for clinicians working with the elderly to remain aware of the potential for TD.
RESUMEN
Haematopoietic insufficiency is the treatment target of lower-risk myelodysplastic syndrome (MDS). Although erythropoiesis-stimulating agents (ESAs) are generally effective for treating anaemia, resistance can develop. Hypoxia-inducible factor-prolyl hydroxylase (HIF-PH) improves renal anaemia by promoting endogenous erythropoietin production and normalizing iron metabolism. HIF-PH inhibitors could be used to treat MDS, but their efficacy and safety have not been studied. A 78-year-old female patient with essential thrombocythemia gradually developed anaemia and was diagnosed with therapy-related MDS 4 years later. The anaemia temporarily improved with ESAs, but the patient became transfusion dependent. At the same time, anaemia and chronic renal failure due to nephrosclerosis progressed, and the patient was diagnosed with MDS with renal anaemia. After switching from ESAs to roxadustat, an HIF-PH inhibitor, anaemia improved, and the patient was no longer transfusion dependent. No progression of the underlying disease or any adverse events was observed 4 months after initiating roxadustat.
RESUMEN
BACKGROUND/OBJECTIVES: Recent studies have revealed thiamine deficiency (TD) as a cause of delirium in cancer patients. However, the extent to which Wernicke encephalopathy is present and in what patients is not well understood. SUBJECTS/METHODS: In this retrospective descriptive study, we investigated referred cancer patients who were diagnosed with delirium by a psycho-oncologist to clarify the proportion of TD, the therapeutic effect of thiamine administration, and the factors involved in its onset. RESULTS: Among 71 patients diagnosed with delirium by a psycho-oncologist, TD was found in 45% of the patients. Intravenous administration of thiamine led to a recovery in about 60% of these patients. We explored the factors associated with TD using a multivariable regression model with a Markov chain Monte Carlo imputation procedure. We found an association between TD and chemotherapy (adjusted odds ratio, 1.98 [95% confidence interval, 1.04-3.77]); however, there were no significant associations between TD and the other factors we considered. CONCLUSIONS: TD is not particularly rare in delirium patients undergoing psychiatric consultation. The delirium was resolved in more than half of these patients by intravenous administration of thiamine. Oncologists should consider TD as a cause of delirium in cancer patients. Further prospective study is needed to clarify the relationship between TD and delirium in cancer patients.

Although there have been recent reports of nonalcoholic thiamine deficiency (TD), no association has been reported between the exacerbation of the psychiatric symptoms of Alzheimer's disease patient and TD. An 89-year-old woman with dementia visited our hospital because of acute deterioration in behavioral and psychological symptoms of dementia (BPSD). Her medical history revealed a decrease in oral food intake lasting more than 2 weeks, so that TD was suspected and abnormal behavior improved significantly after thiamine administration. Thiamine deficiency should be suspected in patients with dementia who demonstrate acute deterioration in BPSD possibly related to poor oral food intake.
RESUMEN
A 69-year-old man was referred to the hematology department for the evaluation of pancytopenia. He had been treated with radiation and epirubicin for hepatocellular carcinoma, and with docetaxel and pembrolizumab for lung adenocarcinoma. Bone marrow smears exhibited markedly increased promyelocytes, and polymerase chain reaction (PCR) study demonstrated chimeric fusion genes of PML-RARA. He was diagnosed with therapy-related acute promyelocytic leukemia (t-APL) and treated with all trans-retinoic acid (ATRA). After 30 days of ATRA treatment, complete hematological response was achieved. To the best of our knowledge, this case represents the first description of successfully treated t-APL diagnosed after treatment with pembrolizumab.

RATIONALE: Intraocular manifestation of hematopoietic tumors is rare and often difficult to distinguish from inflammation. We report a patient with acute lymphoblastic leukemia (ALL) who developed intraocular infiltration during the remission period. PATIENT CONCERNS: A 40-year-old man presented with hypopyon in his right eye. Three months later, extensive subretinal infiltration and the elevation of intraocular pressure were observed. Fourteen months prior to this, he had been diagnosed with Philadelphia chromosome-positive ALL, and had received chemotherapy and bone marrow transplantation that resulted in complete remission. DIAGNOSIS: The breakpoint cluster region-Ableson (BCR/ABL) chimera was detected by polymerase chain reaction (PCR) analysis in the patient's aqueous humor. Additionally, a high expression of WT1 (Wilms tumor gene) mRNA in the aqueous humor was discovered. A bone marrow examination yielded a high expression of BCR/ABL fusion gene, and it was determined the patient had experienced a relapse of ALL. INTERVENTIONS: The dasatinib was administered orally to the patient. OUTCOMES: The intraocular infiltration disappeared, and intraocular pressure was normalized. LESSONS: Intraocular infiltration in leukemia patients may be an indication of relapse regardless of systemic conditions. Analyzing mRNA expression of BCR/ABL and WT1 of ocular fluid in patients with hypopyon is beneficial in diagnosing topical relapses in leukemia.

Escherichia coli (E. coli) causes urinary tract infections, pneumonia, surgical site infections, and bloodstream infections and is the important pathogen for both community-acquired and healthcare-associated infections. To investigate the clonality of E. coli is important for infection control and prevention. We aimed to investigate the clonality of clinical E. coli isolates using Cica Geneus E. coli polymerase chain reaction (PCR)-based open-reading frame typing (POT) KIT and clarify the clinical usefulness of this kit. About 124 E. coli isolates obtained from inpatients at Sapporo Medical University Hospital were used. The POT method was used to classify 124 clinical isolates into 87 POT numbers. In addition to the clonality, it was possible to obtain additional information that 20 of the 124 isolates were extended-spectrum ß-lactamase (ESBL) producing E. coli (5 isolates of CTX-M-1 group and 15 isolates of CTX-M-9 group) and 13 were sequence type (ST) 131 clone. Furthermore, when these ESBL-producing 20 isolates were compared with pulsed-field gel electrophoresis (PFGE) or multilocus sequence typing (MLST), Simpson's index of diversity was 0.968 in POT method, 0.979 in PFGE, and 0.584 in MLST. POT method had an analytical power similar to that of PFGE. In conclusion, attention should be paid to the difference in the interpretation of the results between the POT method and the PFGE, but POT method may be useful to timely monitor the spread of E. coli in medical facilities.

OBJECTIVE: Thiamine deficiency (TD) is recognized in various kinds of disease with associated loss of appetite including cancer. However, it has not been recognized to date in bereaved partners after spousal loss from cancer. METHOD: From a series of bereaved partners who lost a spouse to cancer, we report on those who developed TD after bereavement. RESULT: Case 1 was a 57-year-old woman who sought consultation at our "bereavement clinic." Her husband had been diagnosed with pancreatic cancer one year earlier and had died one month previously. At the first visit, she was observed to suffer depression, anxiety, and decreased appetite. Neurological, blood, and biochemical examinations did not reveal any noteworthy findings. She was diagnosed with uncomplicated bereavement. Detailed examination revealed that her appetite had been markedly decreased for approximately five weeks. The diagnosis of TD was supported by her abnormally low serum thiamine level. Case 2 was a bereaved 73-year-old male who had lost his wife to hypopharyngeal cancer one month previously after a five-year illness. He had shown a lack of energy for the month preceding his wife's death, but because there was no improvement after her death, his family recommended he seek consultation at our "bereavement clinic." He was suffering from major depressive disorder. Detailed examination revealed that his appetite had been decreased for more than two weeks. Again, the diagnosis of TD was supported by his abnormally low serum thiamine level. SIGNIFICANCE OF RESULTS: These reports demonstrate that there is a possibility that bereaved could develop TD after the loss of a loved one. TD should be considered whenever there is a loss of appetite lasting for more than 2 weeks, and medical staff should pay careful attention to the physical condition of the bereaved to prevent complications because of TD.

Composite lymphoma (CL) is defined as the occurrence of two distinct types of lymphoma within the same patient. Most cases of CL involve Hodgkin and non-Hodgkin lymphomas or two distinct types of B-cell lymphomas; true CL is a composite B-cell and T-cell lymphoma, and is rare. We herein report a case involving concurrent extranodal NK/T-cell lymphoma, nasal-type and diffuse large B-cell lymphoma, which has not been previously reported. As the mechanisms and treatments of composite B-cell and T-cell lymphomas are unclear, further studies are required to improve the prognosis.

BACKGROUND: Major BCR-ABL1 mRNA in patients with chronic myeloid leukemia (CML) has generally been analysed by real-time polymerase chain reaction (PCR). Application of the international scale (IS) for the quantification of major BCR-ABL1 mRNA has been recommended in several sets of guidelines, including those of the European LeukemiaNet. The aim of this study was to clarify the efficacy of digital PCR technology for the IS of BCR-ABL1 mRNA in the patients with CML by comparing with real-time PCR. METHODS: The analysis of BCR-ABL1 mRNA was carried out by the Ipsogen® BCR-ABL1 Mbcr IS-MMR DX Kit (Qiagen), and the QuantStudio 3D Digital PCR System (Thermo Fisher Scientific ) using 20 peripheral blood samples obtained from the 9 patients with CML at Sapporo Medical University Hospital. RESULTS: The correlation between the data obtained by digital PCR and by real-time PCR was really high at R = 0.96. The detection limit of digital PCR was up to 0.003% and was equal to IS with 0.01% or less in comparison with real-time PCR. CONCLUSIONS: Digital PCR technology is promising for predicting the IS value with similar efficacy to real-time PCR and should be useful for simple monitoring of the effects of tyrosine kinase inhibitor (TKI) treatments.

OBJECTIVE: Thiamine deficiency (TD) is recognized in various kinds of disease with associated loss of appetite including cancer; however, TD has not been recognized in the family caregivers of cancer patients to date. METHOD: From a series of cancer patient caregivers, we reported an aged family caregiver who developed TD while caring for the cancer patient. RESULT: The caregiver was a 90-year-old male. He had been accompanying his wife, who was diagnosed with colon cancer 4 years previously, on hospital visits as the primary caregiver, but because of psychological issues, he was recommended to visit the psycho-oncology department's "caregiver's clinic" for a consultation. Detailed examination revealed that his appetite had been only about 50% of usual from about one year before, and he had lost 12 kg in weight in one year. The diagnosis of TD was supported by his abnormally low serum thiamine level. SIGNIFICANCE OF THE RESULTS: This report demonstrates that there is a possibility that care providers could develop TD from the burdens associated with caregiving. TD should be considered whenever there is a loss of appetite lasting for more than 2 weeks, and medical staff should pay careful attention to the physical condition of care providers to prevent complications resulting from TD.

OBJECTIVE: Wernicke encephalopathy (WE) is a neuropsychiatric disorder caused by thiamine deficiency, and is sometimes overlooked because of the diversity of clinical symptoms. METHOD: From a series of WE patients with cancer, we report a lung cancer patient who developed WE, the main symptom of which was agitation.ResultA 50-year-old woman with lung cancer was referred to our psycho-oncology clinic because of agitation lasting for three days. No laboratory findings or drugs explaining her agitation were identified. Although the patient did not develop delirium, ophthalmoplegia, or ataxia, WE was suspected because she experienced a loss of appetite loss lasting 5 weeks. This diagnosis was supported by abnormal serum thiamine and disappearance of agitation one hour after intravenous thiamine administration.Significance of resultsThis report emphasizes the clinical diversity of WE and indicates the limits of the ability to diagnose WE from typical clinical symptoms. The presence of a loss of appetite for more than two weeks may be the key to the accurate diagnosis of WE.

OBJECTIVE: Wernicke encephalopathy (WE) is a neuropsychiatric disorder caused by thiamine deficiency. Several reports of WE in cancer patients are known. WE is sometimes overlooked because most patients do not exhibit its typical symptoms (e.g., delirium, ataxia, ocular palsy). If delirium is not present, a diagnosis of WE is difficult because delirium is the hallmark symptom of WE. METHOD: Taken from a series on WE in cancer, we report two patients who developed WE without delirium during periodic psycho-oncology outpatient visits. RESULTS: Case 1. A 61-year-old woman with non-Hodgkin lymphoma who was periodically attending a psycho-oncology outpatient clinic developed an unsteady gait. WE was suspected because she also developed appetite loss for two weeks, and we could find no other laboratory findings to explain her unsteady gait. Our diagnosis was supported by abnormal serum thiamine and disappearance of the gait disturbance after intravenous thiamine administration. Case 2. A 50-year-old woman with breast carcinoma with bone metastasis developed an unsteady gait. WE was suspected because she also developed loss of appetite for two weeks, and no other laboratory findings could explain her unsteady gait. The diagnosis was supported by abnormal serum thiamine and disappearance of the gait disturbance after administration of intravenous thiamine. SIGNIFICANCE OF RESULTS: Our report emphasizes the importance of being aware of WE, even when patients do not present with delirium. The presence of loss of appetite for more than two weeks may be the key to a diagnosis of WE.

Wilms' tumor 1 (WT1) is overexpressed in various hematopoietic tumors and widely used as a marker of minimal residual disease. WT1 mRNA has been analyzed using quantitative real-time polymerase chain reaction (real-time PCR). In the present study, we analyzed 40 peripheral blood and bone marrow samples obtained from cases of acute myeloid leukemia, acute lymphoblastic leukemia, and myelodysplastic syndrome at Sapporo Medical University Hospital from April 2012 to January 2015. We performed quantification of WT1 was performed using QuantStudio 3D Digital PCR System (Thermo Fisher Scientific ) and compared the results between digital PCR and real-time PCR technology. The correlation between digital PCR and real-time PCR was very strong (R = 0.99), and the detection limits of the two methods were equivalent. Digital PCR was able to accurately detect lower WT levels compared with real-time PCR. Digital PCR technology can thus be utilized to predict WT1/ABL1 expression level accurately and should thus be useful for diagnosis or the evaluation of drug efficiency in patients with leukemia.

OBJECTIVE: Thiamine is an essential coenzyme for oxidative metabolisms; however, it is not synthesized in the human body, and the average thiamine storage capacity is approximately 18 days. Therefore, thiamine deficiency (TD) can occur in any condition of unbalanced nutrition. If TD is left untreated, it causes the neuropsychiatric disorder Wernicke encephalopathy (WE). Although WE is a medical emergency, it is sometimes overlooked because most patients with WE do not exhibit all of the typical symptoms, including delirium, ataxia, and ophthalmoplegia. If all of the typical clinical symptoms of WE are absent, diagnosis of TD or WE becomes more difficult. METHOD: From a series of cancer patients, we reported three patients who developed TD without the typical clinical symptoms of WE.ResultA 69-year-old woman with pancreatic body cancer receiving chemotherapy with paclitaxel and gemcitabine for six months. Her performance status (PS) was 1. A detailed interview revealed that she had appetite loss for six months. Another 69-year-old woman with ovarian cancer received nedaplatin; her PS was 0. A detailed interview revealed that she had appetite loss for three months. A 67-year-old woman with colon cancer receiving ramucirumab in combination with second-line fluorouracil with folinic acid and irinotecan. Her PS was 1. A detailed interview revealed that she had appetite loss for three weeks. None exhibited typical clinical signs of WE, but they developed appetite loss for six months, three months, and three weeks, respectively. The diagnosis of TD was supported by abnormally low serum thiamine levels.Significance of the resultsThis report emphasizes the possibility of TD in cancer patients even when patients do not develop typical clinical signs of WE. The presence of appetite loss for more than two weeks may aid in diagnosing TD. Patients receiving chemotherapy may be at greater risk for developing TD.

OBJECTIVE: The purpose of our study was to evaluate the effect of atrial septal defect (ASD) closure on migraine headache attacks (MHA). METHODS: A total of 247 patients who underwent percutaneous ASD closure at our facilities were sent a structured questionnaire. We diagnosed MHA according to the criteria of the International Headache Society. RESULTS: A total of 207 patients were included in the study. New-onset MHA occurred in 23 patients and persisted in 15 at a mean follow-up of 45 months. Of the 29 patients who had MHA prior to ASD closure, 11 reported exacerbation of MHA, 11 reported no change and seven reported improvement within three months after ASD closure. Compared with the patients who had no MHA, patients with de novo MHA were younger and patients with MHA improvement tended to be older. Switching from aspirin to ticlopidine or clopidogrel rapidly aborted frequent MHA in nine patients who had severe symptoms after ASD closure. CONCLUSIONS: These results indicate that Amplatzer device implantation can act as a permanent trigger of MHA in not a few patients, and that age may be an important predictive factor of the influence of ASD closure on MHA.

This prospective study examined the effects of telmisartan, an angiotensin II type I receptor blocker with peroxisome proliferator-activated receptor gamma agonistic action, on blood pressure (BP) control and cerebral circulation in hypertensive patients with chronic-stage stroke. Telmisartan (40 mg per day) was administered to 10 patients with systolic BP (SBP) î¶140 mm Hg and diastolic BP (DBP) î¶90 mm Hg at least 4 weeks after lacunar or atherothrombotic infarction. Casual BP and resting cerebral blood flow (CBF) were evaluated at baseline and week 12 using technetium-99 m ethyl cysteinate dimer single-photon emission computed tomography. Both SBP and DBP declined significantly from 156.4±17.0 to 127.4±6.6 mm Hg and 84.2±14.5 to 74.2±5.2 mm Hg, respectively (P<0.05). Mean CBF (mCBF) in both the left and right cerebral hemispheres did not change, and the mCBF of both the impaired and unimpaired sides of supratentorial lesion patients (n=6) did not change. Investigation of regional CBF in all patients revealed significant increases in the callosomarginal, precentral, central, parietal, temporal, posterior cerebral, lenticular nucleus, thalamic and hippocampal regions at week 12 (P<0.05). Telmisartan showed good antihypertensive activity in hypertensive patients with chronic-stage stroke without affecting hemispheric blood flow, and it even increased regional CBF in most regions examined.
