RESUMEN

Changes in NIRS signals are related to changes in local cerebral blood flow or oxy-Hb concentration. On the other hand, recent studies have revealed the effect of chewing gum on cognitive performance, stress control etc. which accompanied brain activity in the prefrontal cortex (PFC). However, these relationships are still controversial. To evaluate the chewing effect on PFC, NIRS seems to be a suitable method of imaging such results. When measuring NIRS on PFC, blood volume in superficial tissues (scalp, skin, muscle) might have some affect. The aim of the present study was to clarify the effect of the anterior temporal muscle on NIRS signals during gum chewing. Eight healthy volunteers participated. Two-channel NIRS (HOT-1000, NeU, Japan), which can distinguish total-Hb concentrations in deep tissue and superficial tissue layers, was used. In addition to a conventional optode separation distance of 3.0 cm, Hot 1000 has a short distance of 1.0 cm (NEAR channel) to measure NIRS signals that originate exclusively from surface tissues. NIRS probes were placed at Fp1 and Fp2 in the normal probe setting. The headset was displaced to the left in order to allow the left probe to be placed over the left anterior temporal muscle. In the normal setting, the superficial signal curve shows no notable change; however, the neural (calculated and defined in HOT-1000) and deep curves show an increase during the gum chewing task. At the deviated setting, all three signals show marked changes during the task. Total-Hb concentration in the deviated probe setting is significantly large (p < 0.05) than that of in the normal probe setting. When using gum chewing as a task, it would be better to consider a probe position carefully so that the influence of muscle activity on NIRS signal can be distinguished.

RESUMEN

Our previous research confirmed that patients with malignant hematopoietic disease already had a low hemoglobin level before allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, no study has determined whether a correlation exists between exercise load, hemoglobin level, and muscle oxygen saturation (SmO2), during exercise. Therefore, the purpose of this study was to investigate whether near-infrared spectroscopy (NIRS)-derived SmO2 is associated with exercise load, as determined by a dynamometer, before allo-HSCT. This study included 19 male patients who received allo-HSCT in Hyogo College of Medicine Hospital (Japan) between November 2009 and October 2012. Patients performed isometric repeated dorsiflexion at 50% maximum voluntary contraction for 180 s to determine exercise load, and SmO2 was evaluated during exercise at the same time using NIRS (BOM-L1TRW, Omega Wave, Inc., Japan). The hemoglobin level was also evaluated before allo-HSCT. Patients with hematopoietic disease before allo-HSCT already had a low hemoglobin level. There was a significant correlation between exercise load and ∆SmO2; however, the hemoglobin level was not correlated with exercise load. In these patients, exercise load might be affected by muscle oxygen consumption rather than by the hemoglobin level. This finding shows that NIRS can used to assess fatigue in patients with malignant hematopoietic disease.

RESUMEN

Patients with hematological malignancy might already have decreased muscle oxygen saturation at rest and exercise capacity before undergoing hematopoietic stem cell transplantation (HSCT). However, to date, no studies have investigated the relationship between exercise capacity and muscle oxygen saturation at rest in these patients. Therefore, purpose of this study was to investigate the relationship between exercise capacity and muscle oxygen-hemoglobin (O2Hb) saturation (SmO2) at rest and patients' hemoglobin level before undergoing HSCT. METHODS: This study included 60 men with hematologic disease who underwent allo-HSCT. Patients performed a 6-minute walk test (6MWT) to determine exercise capacity, and muscle O2Hb saturation at rest was evaluatabed using near-infrared spectroscopy (BOM-L1TRW, Omegawave Inc., Japan); hemoglobin levels in hematological malignancy patients before undergoing HSCT were also evaluated. RESULTS: There was a significant correlation between the 6MWT and muscle O2Hb saturation at rest in hematological malignancy patients (p < 0.05). Additionally, the 6MWT was significantly correlated to the hemoglobin level (p < 0.05). Furthermore, muscle O2Hb saturation at rest was significantly related to hemoglobin level (p < 0.05). CONCLUSION: In patients with hematological malignancy, a relationship exists between exercise capacity, muscle O2Hb saturation, and hemoglobin level before they undergo HSCT. Therefore, rehabilitation staff, nurses, and physicians should recognize these relationships in patients who undergo allo-HSCT. Moreover, physiotherapists may need to promote muscle oxidative metabolism through exercise to increase exercise capacity in these patients.

RESUMEN

Esophageal cancer surgery originated in the early 20(th) century. However, the true meaning of trans-thoracic esophagectomy and digestive tract reconstruction began in the 1930s. Almost at the same time, Japan and Western countries began the surgical exploration of esophageal cancer. Based on the pathological type of esophageal cancer in Asia, squamous cell carcinoma is the majority, and its biological characteristics and treatment strategies are different from those of European and American patients. After more than eighty years of development, the surgical treatment of esophageal cancer in Japan has been developed from the initial attempt, deep cultivation practice to the pursuit of excellence, and explored a set of more advanced surgical techniques and diagnostic strategies, which is unique in the world. On the basis of the establishment of the Japanese Society of Esophagus, Japanese scholars have developed and irregularly updated the Japanese Classification of Esophageal Cancer and published the professional academic journal Esophagus. The Japanese Clinical Oncology Group organized a number of phase Ⅲ clinical studies on esophageal cancer, providing strong evidence for the diagnosis and treatment of esophageal squamous carcinoma. Focused on the origin, development, current situation and future of esophageal cancer surgery in Japan, this paper summarized the development of esophageal cancer surgery in Japan through literature review, interviews with senior experts and Hot topics of esophageal cancer surgery-questionnaire survey of Japanese experts.

RESUMEN

Bean paste is a confectionery ingredient originating in Asia made from cooked beans and sugar. In Japan, bean paste-containing products play an important role in the traditional confectionery industry. Common beans (Phaseolus vulgaris L.) are used for making white bean paste, and the tebou market class is dedicated to white paste production. Bean paste qualities include paste yield, color, stickiness, smoothness, aroma and flavor. High paste yield, whiteness and smoothness are preferred. The ideal stickiness depends on the final product to be made using bean paste. In terms of aroma and flavor, high sweetness and low beaniness are generally desired. Most of the paste qualities can only be measured by preparing bean paste, which is labor intensive and low throughput. Yuki and Kinu tebou bean varieties were developed in this manner because the highest end-use quality is indispensable to domestic varieties. Tebou bean breeding in Japan is at the stage where more research is necessary to develop faster screening methods to predict important paste quality attributes. This review summarizes the literature on research on white bean paste quality and common bean breeding efforts conducted so far written either in English or Japanese, covering: (1) bean paste production and ingredient sources, (2) the selection criteria and methods used by Japanese breeders and (3) the resulting varieties developed for bean paste. © 2019 Society of Chemical Industry.

RESUMEN

It is important to understand the migration of Cesium (Cs) in soils, particularly after the nuclear power plant accident at Fukushima Dai-ichi, Japan. Dissolved organic matter (DOM) is one of factors affecting the migration of Cs in soils under flowing water conditions. We investigated the effect of DOM on the migration of Cs adsorbed to the clay planar site via laboratory column experiments. The sequence of DOM application had a significant influence on Cs transport in the soil. When DOM was applied concurrently with or prior to Cs application, the DOM adsorbed on to the clay planar site adsorbed onto the soil solid surface and enhanced Cs adsorption; consequently, it slowed Cs migration in the soil. In particular, in the case of DOM loaded prior to the application of Cs solution, a noticeable delay in Cs migration was observed. On the other hand, when DOM was applied to the soil where the Cs solution had been previously applied, the DOM desorbed Cs from the soil. DOM in liquid phase enhanced the migration of Cs through the formation of binding to organic matter. Majority of Cs affected by DOM was the exchangeable fraction that adsorbed to the clay planar site. In other words, DOM attached to the soil would adsorb Cs as a easily exchangeable form and depress migration of Cs. On the other hand, DOM in the soil solution may up take adsorbed Cs from the soil and enhanced the transport in the form of Cs bound to DOM.

RESUMEN

BACKGROUND: It is known that once heart failure occurs in older patients with diabetes, the overall prognosis is extremely poor. We investigated whether early initiation of SGLT2 inhibitor therapy after admission was beneficial for diabetic patients requiring inpatient treatment for acute heart failure. METHODS: We retrospectively assessed consecutive patients with comorbid diabetes who were admitted to the Department of Cardiology in Tosei General Hospital for treatment of acute heart failure. Patients were divided into two groups: those who initiated SGLT2 inhibitor therapy (SGLT2 inhibitor group; mean age: 73 ± 9 years) and those who did not receive the inhibitors during hospitalization (conventional treatment group; mean age: 75 ± 10 years). RESULTS: No intergroup differences were observed in the distribution of either the severity or classes of heart failure on admission. Glycosylated hemoglobin levels were significantly higher in the SGLT2 inhibitor group (HbA1c: 8.1% ± 0.8%) than in the conventional treatment group (HbA1c: 7.1% ± 0.8%) (p = 0.003). After admission, patients in both groups recovered equally well, and in almost the same period of time, before discharge. The rate of diuretics use at the time of discharge in the SGLT2 inhibitor group (n = 8, 67%) was significantly lower than that in the conventional treatment group (n = 19, 100%) (p = 0.016). In particular, the dose of loop diuretics in the conventional treatment group was 34 ± 4 mg/day while that in the SGLT2 inhibitor group was significantly lower at 13 ± 5 mg/day (p = 0.008). During hospitalization, the incidence of acute kidney injury was significantly higher in the conventional treatment group (n = 11, 58%) than in the SGLT2 inhibitor group (n = 2, 16%) (p = 0.031). CONCLUSIONS: For the treatment and management of heart failure in patients with diabetes, early initiation of SGLT2 inhibitor therapy appears to be effective.

RESUMEN

The incidence of breast cancer among Japanese women is substantially increasing. This study evaluated the effects of reproductive and lifestyle factors with respect to breast cancer overall and separately among pre- and postmenopausal women using data from the Three-Prefecture Cohort Study of Japan.A total of 33,410 women aged 40 to 79 years completed a self-administered questionnaire, which included items about menstrual and reproductive history and other lifestyle factors. The follow-up period was from 1984 to 1992 in Miyagi and 1985 to 2000 in Aichi Prefectures. We used Cox proportional hazards regression models to estimate hazards ratios (HRs) and 95% confidence intervals (CIs) after adjusting for confounding factors.After 9.8 mean years of follow-up, 287 cases of breast cancer were recorded. In the overall analysis, later menarche (≥16 years) and parity were significantly associated with a decreased risk of breast cancer, with HRs of 0.69 (95% CI 0.48-0.99) and 0.72 (95% CI 0.52-0.99), respectively. Further, there was a significant decline in the risk of breast cancer with increasing number of birth among parous women (P for trend = .010). On the contrary, a family history of breast cancer in the mother was significantly associated with an increased risk of breast cancer (HR 3.22, 95% CI 1.52-6.84). Analyses based on menopausal status at baseline indicated that height (≥160 cm) and weight (≥65 kg) were significantly associated with an increased risk of postmenopausal breast cancer, with HRs of 1.34 (95% CI 0.72-2.50) and 3.13 (95% CI 1.75-5.60), respectively. Risk associated with BMI significantly differs by menopausal status.Our findings suggest the important role of reproductive factors in the development of breast cancer in Japanese women; however, body mass index (BMI) may have different effects on breast cancer in Japanese women compared with western women.

RESUMEN

Introduction: Acute acoustic trauma, which is a kind of sensorineural hearing loss, is caused by acoustic overstimulation. Hyperbaric oxygen therapy (HBOT) is reported to be effective against acute acoustic trauma. Objective: We aimed to evaluate the efficacy of HBOT against acoustic hearing loss based on our 20 years of experience with such cases. Methods: Patients who were treated with HBOT for acute acoustic trauma between April 1997 and August 2017 were evaluated in this study. Thirty-five patients with a mean age of 25.7 ± 9.2 (range: 16­48) years were included. Thirty-nine out of 70 ears (35 patients) were damaged. We investigated the initial level of hearing loss; the extent to which hearing recovered; subjective symptoms, such as tinnitus and aural fullness; and the treatment administered. Results: The planned HBOT was completed in 37 of 39 ears. Twenty-six of the 37 ears (70.2%) displayed improved hearing, and 31 of the 37 ears (83.9%) exhibited symptom improvement. Twenty-three (76.7%) and 26 (86.7%) of the 30 ears treated with steroids demonstrated improvements in hearing and subjective symptoms, respectively. Conclusion: A combination of HBOT and steroids should be considered as a treatment for acute acoustic trauma in cases involving symptoms such as tinnitus and aural fullness (AU)

RESUMEN

As part ofthe medical system in Japan, one ofthe initial steps in palliative care involves cancer patient guidance management feeⅠ(counselingⅠ)by a nurse. However, due to poor cooperation between doctors and nurses, the rate ofcounseling Ⅰ is currently low. Therefore, at our hospital, we collaborated with clinical laboratory technicians to inform, at the same time, both the certified nurse and doctor of the patient's diagnostic test results regarding any malignant findings in the pathological tissue examination. Then, we initiated efforts to inform the doctor about the implementation of counselingⅠ positively by certified nurses. As a result, it was possible to set a reliable list oftarget patients, and the number ofcounseling Ⅰ sessions increased by 1.5 times. In addition, these findings suggest the possibility ofreducing the burden ofdoctors by counselingⅠ.

RESUMEN

Improvement in patient safety culture requires constant attention. This study aimed to identify hospital-level elements related to patient safety culture, such as patient safety management systems, activities and work environments.Two questionnaire surveys were administered to hospitals in Japan in 2015 and 2016. The first survey aimed to determine which hospitals would allow their staff to respond to a questionnaire survey. The second survey aimed to measure the patient safety culture in those hospitals. Patient safety culture was assessed using the Hospital Survey on Patient Safety Culture (HSOPS). The relationship of hospital-level patient safety culture with the aforementioned elements in each hospital was analyzed.The response rate to the first survey was 22% (721/3270), and 40 eligible hospitals were selected from the respondents. The second survey was administered to healthcare workers in those 40 hospitals, and the response rate was 94% (3768/4000). The proportion of respondents who had 7 or more days off each month was related to the scores of 7 composites and the Patient Safety Grade of HSOPS. Both the presence of a mission statement describing patient safety and the proportion of respondents who participated in in-house patient safety workshops at least twice annually were related to the scores of 5 composites and the Patient Safety Grade of HSOPS.Our study suggests that the number of days off each month, the presence of a hospital patient safety mission statement, and the participation rate in in-house patient safety workshops might be key factors in creating a good patient safety culture within each hospital.

RESUMEN

BACKGROUND/AIM: The present study aimed to examine the influence of antibiotics (AB) on the clinical outcomes of Japanese patients treated with immune check point inhibitors (ICIs) for metastatic renal cell carcinoma (RCC) patients. PATIENTS AND METHODS: A total of 31 patients with metastatic RCC treated with ICIs from November 2016 to April 2019 were retrospectively reviewed and analyzed. RESULTS: Five patients were treated with AB prior to ICIs treatment. Median progression free survival (PFS) of patients treated with AB vs. patients not treated with AB was 2.8 months and 18.4 months, respectively. The difference between PFS was statistically significant (p=0.0004). In multivariate analyses, AB use (p=0.0377) and presence of immune related adverse events (p=0.0042) were independent prognostic factors for PFS in association with ICIs therapy. CONCLUSION: The use of AB before ICIs treatment was a predictor of poor ICIs response in metastatic RCC.

RESUMEN

Although chronic constipation is highly prevalent, its definition remains unclear. Therefore, the prevalence varies depending on reports, and the understanding of actual situations is unclear. Hence, we performed an internet survey on constipation among the Japanese general population to study the background factors and actual situations. Preliminary study on the awareness of constipation was conducted among 10000 people in which 9523 of them was asked if they had constipation at the time of the survey. In this population, 51.5% realized that they had constipation. Multivariate analysis showed the significant association of constipation to age, sex, and past histories or complications of diabetes, hemorrhoids, and cerebrovascular diseases. In a main research composed of 3000 general Japanese population, approximately 30.9% of the subjects reported the use of laxatives to treat constipation, and 43.8% of them were found to use irritant laxatives. Moreover, 67.5% of the subjects purchased laxatives at a pharmacy. The frequency of bowel movement less than 3 times per week was manifested in 36.3% of the subjects, and more than once per week in 21.4%. The percentage of hard (Bristol Stool Form Scale [BSFS] Type 1-2), normal (BSFS Type 3-5), and diarrhea stools (BSFS Type 6-7) was 33.1%, 60.0%, and 6.9%, respectively. The quality of life (QOL) of the subjects with hard and diarrhea stools evaluated by SF-8 was significantly lower than that of those with normal stools. Furthermore, the actual monthly cost for the therapeutic drugs used for treating constipation was less than 1000 yen in 75% of the subjects. Analysis of the IBS-QOL-J indicated that the ≥5000 yen payable group had the lowest satisfaction of defecation among the study groups. At present, many Japanese patients with constipation have not been receiving enough treatment for constipation. Therefore, appropriate medication by physicians as well as instruction to patients is required.

RESUMEN

Medinodexia japonica sp. nov. is described from Japan and an adult leaf beetle, Aulacophora nigripennis Motschulsky (Coleoptera: Chrysomelidae), is recorded as its host. A piercing-type ovipositor is one of the characteristics of the genus Medinodexia Townsend, but it is also found in other blondeliine genera. To evaluate the structural differences of the piercing-type ovipositor, the female postabdominal characters were examined within Blondeliini and their phylogenetic implications are briefly discussed. Females of Medinodexia are similar to those of Medina Robineau-Desvoidy for the presence of invaginations on tergite 6 and sternite 6 of the abdomen. Medinodexia exigua Shima and M. orientalis Shima are not treated here, because they are considered to belong to an undescribed genus due to differences in the male and female postabdominal characters distinguishing them from the remaining species of Medinodexia.

RESUMEN

The systematic status of Gelechia acanthopis Meyrick, 1932 is reviewed. The general and functional morphology of the male genitalia merits a new genus in Pexicopiini, Sitotrogoides gen. nov., for G. acanthopis. The musculoskeletal apparatus of the male genitalia in Sitotrogoides is described for the first time and compared with allied genera. The taxonomic position of the genus Sitotrogoides is determined within the tribe Pexicopiini. The lack of the muscle m3 is suggested as a characteristic associating Sitotrogoides with Sitotroga and differing from all other genera in Pexicopiini. The type species of Sitotrogoides, Gelechia acanthopis Meyrick is redescribed. Our new records of Sitotrogoides acanthopis from Korea suggest its extended distribution out of Japan.

RESUMEN

Notes are provided for six microcaddisfly species (Trichoptera, Hydroptilidae) in the Japanese fauna. One is a new species, Hydroptila nago Ito sp. nov., described from southern Japan. The second and third, Hydroptila dorsoprocessuata Botosaneanu 1993, previously known from eastern Russia, and Hydroptila introspinata Zhou and Sun 2009, known from northeastern China and Korea, are recorded from Japan for the first time and redescribed. A fourth, Hydroptila parapiculata Yang and Xue 1994, is known from central and southeastern China and central Japan; the male is redescribed. By synonymizing Ugandatrichia shinshiroensis Ito et al. 2018, described from central Japan, with a Chinese species, Allotrichia rhynchophyllum Zhou et al. 2016, we record the genus Allotrichia McLachlan from Japan for the first time. For a sixth species, Stactobia distinguenda Nozaki and Botosaneanu 1996, previously known in Japan from the male only, the larva and its case are described.
