Abstract
Accurately measuring blood pressure (BP) is essential for maintaining physiological health, which is commonly achieved using cuff-based sphygmomanometers. Several attempts have been made to develop cuffless sphygmomanometers. To increase their accuracy and long-term variability, machine learning methods can be applied for analyzing photoplethysmogram (PPG) signals. Here, we propose a method to estimate the BP during exercise using a cuffless device. The BP estimation process involved preprocessing signals, feature extraction, and machine learning techniques. To ensure the reliability of the signals extracted from the PPG, we employed the skewness signal quality index and the RReliefF algorithm for signal selection. Thereafter, the BP was estimated using the long short-term memory (LSTM)-based neural network. Seventeen young adult males participated in the experiments, undergoing a structured protocol composed of rest, exercise, and recovery for 20 min. Compared to the BP measured using a non-invasive voltage clamp-type continuous sphygmomanometer, that estimated by the proposed method exhibited a mean error of 0.32 ± 7.76 mmHg, which is equivalent to the accuracy of a cuff-based sphygmomanometer per regulatory standards. By enhancing patient comfort and improving healthcare outcomes, the proposed approach can revolutionize BP monitoring in various settings, including clinical, home, and sports environments.

Abstract
Heatstroke is a concern during sudden heat waves. We designed and prototyped an Internet of Things system for heatstroke prevention, which integrates physiological information, including deep body temperature (DBT), based on the dual-heat-flux method. A dual-heat-flux thermometer developed to monitor DBT in real-time was also evaluated. Real-time readings from the thermometer are stored on a cloud platform and processed by a decision rule, which can alert the user to heatstroke. Although the validation of the system is ongoing, its feasibility is demonstrated in a preliminary experiment.

Abstract
Abstract
Study question
Does the presence of the ACA have any effect on pregnancy and birth?
Summary answer
Presence of ACA did not have an impact on pregnancy and birth parameters measured.
What is known already
We have previously shown that patients with high levels of anti-centromere antibody (ACA), one of the anti-nuclear antibodies (ANA), frequently have dispersion of chromosomes in the cytoplasm. Additionally, we reported that it was characterized by a low oocyte maturation rate as observed at ovum pick up, high multiple pronuclear formation after fertilization and a low pregnancy rate after embryo transfer. Thus, the effect of ACA on fertility is clear, but the impact following pregnancy establishment has not yet been reported. Therefore, we followed up on birth outcomes in ACA-positive patients treated with ART.
Study design, size, duration
3379 patients who underwent ANA testing followed by embryo transfer between January 2014 and February 2020 and who gave birth including the results of single births with no abnormal or missing values for week and birth weight were analyzed. The subjects were classified into three groups: ANA-negative (without ACA or any other ANA), ACA-positive (with only ACA) and ANA-positive (with ANA but not ACA).
Participants/materials, setting, methods
We compared mean birth weight (full term), low weight birth infant (less than 2,500g) rate, sex ratio, congenital anomaly rate, preterm birth rate, cesarean section rate, and mean apgar score (AP) in the three groups. We treated “don't know” and “blank” for items other than week and birth weight as non-responses and missing values.
Main results and the role of chance
Of the 3379 cases for analysis, the group numbers were ANA-: 2465, ACA+: 21, ANA+: 893. The mean birth weights were 3099.6g, 3055.3g and 3088.5g respectively. In the 3 groups the rate of low birth weight infants were 8.7% (215/2465), 9.5% (2/21) and 9.2% (82/893), the sex ratio (male/female)-1.03 (1246/1212), 0.62 (8/13) and 0.93 (429/ 460), congenital anomaly rate 2.7% (67/2465), 4.8% (1/21), 3.2% (29/893), preterm birth rate 7.4% (86/2465), 4.8% (1/12), 6.7% (60/893), cesarean rate 40.0% (979/2448), 42.9% (9/21), 41.3% (367/888), and mean AP was 8.3, 8.2, and 8.3 respectively. There was no significant difference between the three groups in any of the measured items.
Limitations, reasons for caution
This study was conducted at a single institution, and only the results of those who responded to the birth survey questionnaire were analyzed. Because of the small number of patients in the ACA group, continued follow-up is considered necessary.
Wider implications of the findings
It was shown that ACA strongly affects maternal fertility, but seems to have no effect on birth parameters. However we will continue to follow up with further long-term prognostic studies.

Abstract
Patients experiencing severe side effects when taking high-risk drugs may have a significantly reduced health-related quality of life (QOL); therefore, it is important to identify changes in the health-related QOL in these patients. This study aimed to determine the health-related QOL in community pharmacy outpatients taking high-risk drugs. This prospective observational study was conducted in 29 community pharmacies with 71 pharmacists in 12 regions and cities in Japan from October to December 2020 and 760 patients were enrolled. Using descriptive questionnaires of EuroQOL-5-dimensions-5-levels (EQ-5D-5L), community pharmacists obtained health-related QOL data from outpatients taking high-risk drugs. The mean health-related QOL of all outpatients was 0.869. The health-related QOL decreased with increasing age. The outpatient health-related QOL was 0.700, 0.763, 0.785, and 0.817 when taking antiepileptic, antidepressant, digitalis, and antiarrhythmic drugs, respectively, which was lower than the average health-related QOL of all outpatients. Mobility and pain/ discomfort accounted for a large proportion of the decline in the health-related QOL with increasing age. There were no significant differences in personal care with increasing age; however, the number of outpatients with mobility, normal activity, and pain challenges decreased with age. In contrast, outpatients aged <65 years with anxiety/depression showed a lower than overall average health-related QOL. To the best of our knowledge, this is the first study in Japan to report an investigation by community pharmacists regarding health-related QOL assessment in outpatients taking high-risk drugs.

Abstract
Vincristine (VCR) is an important drug used in R-CHOP regimens for the treatment of non-Hodgkin's lymphoma. The purpose of this study was to examine whether the administration method affects the incidence of VCR-induced peripheral neuropathy. We investigated the ratio of VCR-induced peripheral neuropathy during rapid intravenous infusion and intravenous drip infusion. A total of 71 patients who had received six or more courses of R-CHOP from January, 2015 to December, 2016 at Komaki City Hospital and Ogaki Municipal Hospital were retrospectively investigated. Peripheral neuropathy was observed in 27/39 patients (69 %) and 24/32 (75 %) in rapid intravenous infusion and intravenous drip infusion of VCR, respectively (P = 0.79). Peripheral neuropathy was observed at a high frequency in this study. Additionally, there was no difference in frequency of peripheral neuropathy due to the difference in administration method. In both groups, the degree of peripheral neuropathy was grade 1 and grade 2 in most patients. However, in rapid intravenous infusion, grade 3 peripheral neuropathy was observed. Some cases required dose reduction and discontinuation in rapid intravenous infusion. In contrast, there were no discontinuing patients in the intravenous drip infusion. Therefore, it was suggested that intravenous drip infusion of VCR reduced serious peripheral neuropathy because the ratio requiring dose reduction and discontinuation was less than that in the rapid group. In conclusion, this study is informative as there are few reports focusing on the administration method of vincristine.

Abstract
Cribriform lymph node pattern is an independent risk factor for metachronous or synchronous distant metastasis in patients with stage III and IV node-positive colorectal cancer. Multivariable analysis in patients with stage III disease indicated that the cribriform pattern of carcinoma in the lymph nodes was an independent risk factor for recurrence and survival. Kaplan–Meier analysis demonstrated that the group with stage III cribriform-type lymph node carcinoma had shorter recurrence-free and overall survival times than the stage III group with the tubular type (P < 0.001).

Abstract
Study question
Do ACA have an effect on pregnancy and miscarriage rates of human embryos?
Summary answer
The present results suggest that in ACA-positive cases, the pregnancy rate per transfer was significantly lower, although the miscarriage rate was not affected.
What is known already
We have previously shown that patients with high levels of anti-centromere antibody (ACA), (one of the anti-nuclear antibodies (ANA)), frequently have dispersal of the female chromosomes in the cytoplasm. Additionally, we reported that the clinical outcome was characterized by a low oocyte maturation rate following ovum pick up and high multiple pronuclear formation rate after fertilization. However, the post-implantation course of embryos with ACA-positive cases has not yet been reported. Therefore, in this study, we analyzed the pregnancy and miscarriage rates in ACA-positive patients treated with Assisted Reproductive Technologies (ART).
Study design, size, duration
6581 patients who underwent embryo transfer after antinuclear antibody testing between January 2014 and February 2020 were included in the analysis.
Participants/materials, setting, methods
The subjects were classified into three groups: ANA-negative (without ACA or any other ANA), ACA-positive (with only ACA) and ANA-positive (with ANA but not ACA). The cycle in which the gestational sac was confirmed was considered a positive pregnancy. The pregnancy and miscarriage rates were compared among the groups using “Ryan Test” for statistical analysis.
Main results and the role of chance
Of the 6581 eligible cases, the incidence of antinuclear antibody were 71.3% (4695/6581; ANA-negative), 0.9% (61/6581; ACA-positive) and 27.7% (1825/6581; ANA-positive). The pregnancy rates based on the total number of embryo transfer cycles for each were ANA-negative: 31.5% (5283/16792), ACA-positive: 17.6% (41/233), and ANA-positive: 32.4% (1891/5833). The pregnancy rates were significantly lower in the ACA-positive group than in the other groups. The miscarriage rate was 29.4% (1553/5283) in ANA-negative, 31.7% (13/41) in ACA-positive, and 28.0% (529/1891) in ANA-positive, with no significant difference between the three groups.
Limitations, reasons for caution
Retrospective analysis
Wider implications of the findings: ACA-positive patients may benefit from a treatment strategy to increase the absolute number of oocytes by obtained in order to increase the chances of normal fertilization and attainment of implantation.

Abstract
This study aimed to identify the overall survival prolongation index in patients who received paclitaxel plus ramucirumab as second line chemotherapy for human epidermal growth factor receptor (HER) 2-negative advanced/ recurrent gastric cancer (AGC). We included 77 patients who underwent second line chemotherapy (paclitaxel plus ramucirumab) for AGC at our institution between January 2015 and September 2020. To determine factors associated with survival, univariate and multivariate analyses were performed, and hazard ratios and their 95% confidence intervals (95% CI) were calculated. In the multivariate analysis, grade ≥1 neutropenia (yes) and the number of anti-cancer drugs used (≥5) were independently and significantly associated with survival. Compared to the patients without grade ≥1 neutropenia, patients with grade ≥1 neutropenia had a survival hazard ratio of 0.455 (95% CI: 0.214-0.966; p = 0.040). The median second line treatment durations in patients with grade ≥1 neutropenia (n = 54) and in those without grade ≥1 neutropenia (n = 23) were 133 days (95% CI, 98-190 days) and 70 days (95% CI, 41-128 days), respectively (log-rank test, p = 0.026). This study demonstrated that AGC patients with initial neutropenia may benefit from paclitaxel plus ramucirumab therapy.

Abstract
This study aimed to clarify the relationship between neutropenia and progression-free survival (PFS) under palbociclib treatment for advanced/recurrent breast cancer and the risk factors for severe neutropenia. We retrospectively identified 37 patients who received palbociclib for advanced breast cancer at Ogaki Municipal Hospital (Ogaki, Japan) between April 2018 and June 2020. Kaplan-Meier log-rank test was used to compare PFS (mild [neutrophil count 1,000-2,000/mm 3 ] versus severe [neutrophil count <500-1,000/mm³]). Multivariate analysis was performed to evaluate the relationships between baseline patient characteristics and severe neutropenia development. There were three, four, 25, and five cases with grade 1, 2, 3, and 4 neutropenia, respectively. Median PFS in patients who developed severe neutropenia (n = 30) and those who did develop mild neutropenia (n = 7) was 176 days (range: 62-894 days) and 91 days (range: 19-384 days), respectively (log-rank test, p = 0.005). Severe neutropenia was independently associated with pre-treatment neutrophil count (odds ratio: 27.700; p =0.007). Severe neutropenia is more likely to occur with a pre-treatment neutrophil count of less than 3,680 mm³. Neutropenia prolongs PFS under palbociclib treatment, suggesting management of AEs and patient education as highly important, especially to prevent drug interruption/dose reduction of palbociclib due to these AEs.

Abstract
Long-term azacitidine (AZA) treatment is necessary for its maximal therapeutic effect. This study examined the continuity and efficacy of AZA treatment in real-world use. We conducted a retrospective study in 38 patients who had completed AZA treatment at the Ogaki Municipal Hospital between April 2011 and August 2019. The median number of AZA received cycles was 4. The number of AZA treatment cycles received was 1-3 cycles in 15 (39.5%), 4-6 cycles in 15 (39.5%), and ≥ 7 cycles in 8 (21.1%). The most common reason for discontinued AZA treatment was infection. Overall response rate was 33.3% in patients with discontinued AZA use (< 4 cycles) and 56.5% in patients with continued AZA (≥ 4). Median overall survival (OS) was 124 (15-529) days and 391 (132-2,825) days in the respective groups (p<0.01). The presence of peripheral blood blasts (PBs) was a prognostic factor for continuation of treatment (p =0.03). Discontinued AZA treatment due to infection (p <0.01), and PBs (p =0.03) were unfavourable prognostic factors for OS. Long-term AZA use is beneficial for improvement and survival. Infection control and presence of PBs were important factors for continuing AZA. These data support the idea of long-term continued treatment with AZA for optimal benefit to patients.

Abstract
An isothermal cascade reaction that exponentially amplifies pre-designed, single-stranded DNA as a sensor and signal amplifier module for DNA-based computing and molecular robotics was developed. Taking advantage of the finding that locked nucleic acid can suppress problematic ab initio DNA synthesis, up to million-fold amplification rates and concurrent hybridization were achieved at a physiological temperature in a single reactor. Although the effect of locked nucleic acid introduction to the templates was complicated, undesired leak DNA amplification was generally suppressed in the amplification reaction for distinct DNA sequences. The present reaction that senses one DNA as an input and generates a large amount of another DNA as an output, exhibiting a high correlation between the molecular concentration and the amplification time, is applicable for nucleic acid quantification.

Abstract
This retrospective study compares the economic superiority of palbociclib versus everolimus for advanced and recurrent breast cancer. Furthermore, we investigated the safety and treatment continuity of palbociclib and everolimus regimens. Expected costs were calculated based on data from patients with advanced and recurrent breast cancer who were treated with palbociclib and everolimus. The progression-free survival (PFS) from the PALOMA-3 clinical trial and BOLERO-2 clinical trial was used to evaluate the therapeutic efficacy of the regimens. The cost-effectiveness ratio of each chemotherapy agent was calculated by dividing the expected cost by the progression-free survival (PFS). The cost-effectiveness ratio per month was JPY 391,551.3/PFS for palbociclib and JPY 488,690.5/PFS for everolimus (p=0.627). The incremental cost-effectiveness ratio per month of everolimus to palbociclib was JPY 100,133.7/PFS. For patients receiving everolimus, adverse drug reactions included stomatitis (77.3%), rash (59.1%) and leukopenia (59.1%). For patients receiving palbociclib, neutropenia (69.2%), leukopenia (69.2%) and anemia (30.8%) occurred. In terms of discontinuation owing to adverse events (AEs), pneumonitis, thrombocytopenia, edema, fatigue, and neutropenia were experienced in the everolimus group. The cost-effectiveness of everolimus and palbociclib are equivalent, but since the prevalence of AEs is high in patients receiving everolimus, its AE management is important.

Abstract
Abstract
Novel analytical methods based on real-time quantitative polymerase chain reactions by use of new reference molecules were validated in interlaboratory studies for the quantitation of genetically modified (GM) maize and soy. More than 13 laboratories from Japan, Korea, and the United States participated in the studies. The interlaboratory studies included 2 separate stages: (1) measurement tests of coefficient values, the ratio of recombinant DNA (r-DNA) sequence, and endogenous DNA sequence in the seeds of GM maize and GM soy; and (2) blind tests with 6 pairs of maize and soy samples, including different levels of GM maize or GM soy. Test results showed that the methods are applicable to the specific quantitation of the 5 lines of GM maize and one line of GM soy. After statistical treatment to remove outliers, the repeatability and reproducibility of these methods at a level of 5.0% were <13.7 and 15.9%, respectively. The quantitation limits of the methods were 0.50% for Bt11, T25, and MON810, and 0.10% for GA21, Event176, and Roundup Ready soy. The results of blind tests showed that the numerical information obtained from these methods will contribute to practical analyses for labeling systems of GM crops.

Abstract
S-1 and cisplatin therapy (SP therapy) is widely used as the first-line of advanced/recurrent gastric cancer. However, severe neutropenia is often observed (40%) during this therapy. Therefore, the risk management of neutropenia is important. From September 2014 to April 2017, we investigated 76 patients who underwent SP therapy as primary treatment for advanced/recurrent gastric cancer at Ogaki Municipal Hospital. Risk factors for grade 3/4 neutropenia were examined by univariate and multivariate analyses. In SP therapy, 19 patients (25%) experienced grade 3/4 neutropenia. The results of multivariate analysis of factors with p <0.05 in the univariate analysis indicated that less than 10.6 g/dL of the haemoglobin value before the course at the lowest neutrophil count (odds ratio: 7.900; 95% CI: 1.280-48.60; p = 0.026), more than six courses of the total course (odds ratio: 9.13; 95% CI: 2.13-39.1; p = 0.003), and less than 3140 m2 neutrophil counts (odds ratio: 5.33; 95% CI: 1.47-19.3; p = 0.011) before chemotherapy were risk factors of grade 3/4 neutropenia. A low haemoglobin value before the course at the lowest neutrophil count was revealed as a risk factor causing severe neutropenia in SP therapy.

Abstract
For patients with advanced/recurrent colorectal cancer, the trifluridine/tipiracil combination tablet (TAS 102) and regorafenib are last-line treatments. This study aimed to clarify prognostic factors in patients receiving last-line chemotherapy. Between April 2014 and December 2016, 47 patients received last-line chemotherapy at Ogaki Municipal Hospital, Japan. The primary outcome was overall survival. To determine factors associated with survival, those considered significant in the univariate analysis (p <0.10), were entered into a multivariate Cox proportional hazards model. KRAS type and the use of opioid formulations were independently and significantly associated with survival in the multivariate analysis. For patients with KRAS-wild relative to KRAS-mutation cancers, the hazard ratio for death was 0.478 (95% CI, 0.249-0.919; p = 0.03). For patients taking opioid formulations, relative to those not, the hazard ratio for death was 3.557 (95% CI, 1.032-12.257; p = 0.04). The median overall survival duration for patients with KRAS-wild (n = 24) and KRAS-mutation (n = 23) cancers were 223.5 days (range: 115-703) and 154 days (range: 51-503), respectively (p = 0.05). This finding provides a useful index to make an early decision on discontinuation of treatment and to guide decisions around agents to use in last-line chemotherapy.

Abstract
Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), including gefitinib, erlotinib and afatinib are standard first-line treatments for EGFR gene mutation-positive non-small cell lung cancer. The present study aimed to compare the cost-effectiveness of using erlotinib, afatinib or gefitinib. The safety of EGFR-TKIs was also investigated. Expected costs were calculated based on data from patients with advanced EGFR mutation-positive non-small-cell lung cancer who were treated with gefitinib, erlotinib or afatinib. Literature was collected to obtain the necessary clinical information for calculating the probability and the validity of each chemotherapy. Median survival time (MST) was used to evaluate the therapeutic effect of the regimens. The cost-effectiveness ratio was calculated using expected costs and MSTs for the three regimens. The cost-effectiveness ratio per month was JPY 386,859.4/MST for afatinib, JPY 264,788.7/MST for gefitinib and JPY 397,039.9/MST for erlotinib. Significant differences were observed between the three groups (p<0.001). The incremental cost-effectiveness ratio (ICER) of gefitinib compared with afatinib per month was JPY 122,070.7/MST. The ICER of gefitinib compared with erlotinib was JPY -69,605.9/MST. Adverse effects of Grade 3 and higher, including diarrhoea (28.6%) and paronychia (14.3%) were observed in the afatinib treatment group. Paronychia (23.1%) was observed in the erlotinib treatment group, while none were observed in the gefitinib treatment group. These findings demonstrate that gefitinib is more cost effective in comparison with the afatinib and erlotinib regimens, although the afatinib and erlotinib regimens were well-tolerated and produce sufficient effects.

Abstract
Laboulbeniopsis termitarius (Thaxt) and Antennopsis gallica (Buchli and Heim) are two of the most common ectoparasitic fungi found on the body surface of termites. While visual observation under a dissecting microscope is a common method used to screen for such fungi, it generally requires a large number of termites and is thus very time consuming. In this study, we develop a fast, efficient protocol to detect fungal infection on the termite Reticulitermes speratus (Kolbe). Species-specific primers were designed based on sequence data and amplified using a number of universal fungus primer pairs that target partial sequences of the 18s rRNA gene of the two fungi. To detect these fungi in a robust yet economic manner, we then developed a multiplex nested polymerase chain reaction assay using species-specific primers. Results suggested that both fungi could be successfully detected, even in cases where L. termitarius was at low titer (e.g., a single thallus per termite). The new method described here is recommended for future surveys of these two fungi, as it is more sensitive, species specific, and faster than visual observation, and is likely to facilitate a better understanding of these fungi and their dynamics in host populations.

Abstract
The 125I pulse-height spectra via a liquid scintillation counter (LSC) displayed notable variations. The counting efficiencies of higher and lower energy peaks increased and decreased, respectively, with the enhancement of the amount of high atomic numbered elements within the cocktails. This tendency was ascribed to the increasing probability of the interaction of photons with the scintillation cocktail. Moreover, it was noted that the shape of a 125I spectrum strongly depends on the amount of high atomic numbered elements.

Abstract
As a result of the RAINBOW trial, ramucirumab plus paclitaxel was established as a second-line treatment of advanced gastric cancer. Regarding the safety of ramucirumab plus paclitaxel in the Japanese, a subgroup analysis of the RAINBOW trial was conducted. The incidence of neutropenia was higher in Japanese patients. However, information is lacking concerning the safety of ramucirumab after marketing in Japanese patients. Therefore, the aim of this study was to evaluate the safety of ramucirumab in Japanese patients with advanced gastric cancer. The inclusion criteria were patients diagnosed with advanced gastric cancer who had commenced treatment with ramucirumab plus paclitaxel or paclitaxel only at Ogaki Municipal Hospital (Gifu, Japan) between January 2015 and December 2016. There were 26 patients in the ramucirumab plus paclitaxel group and 22 patients in the paclitaxel only group. Treatment-related adverse events were documented in 100.0% of the patients in the ramucirumab plus paclitaxel group (Grade 3-4, 73.1%) and 90.9 % of the patients in the paclitaxel only group (Grade 3-4, 45.5 %). The most frequently observed adverse event in both treatment groups was anemia. The second common adverse event was neutropenia. The incidence of neutropenia of Grade ≥3 was significantly higher in the ramucirumab plus paclitaxel group than in the paclitaxel only group. In conclusion, the incidence of neutropenia is high. However, we believe that ramucirumab plus paclitaxel can be safely administered.

Abstract
Vitamin (V) K deficiency may cause severe bleeding tendencies, which necessitates extreme caution. We report a case of a 30-year-old man diagnosed with VK deficiency of unknown etiology. He was treated with intravenous menatetrenone three times a week in an outpatient setting for about 1 year and 9 months. Eventually, he developed an allergic reaction to intravenous menatetrenone and was under steroid therapy. In order to reduce his hospital visits and discontinue steroid use, the pharmacist proposed to change the method of menatetrenone administration from intravenous to oral (high dose). The change in treatment method has greatly improved the patient's quality of life.

Abstract
Elucidating the factors influencing severe neutropenia could aid in earlier management of neutropenia during oral trifluridine-tipiracil (TAS-102) chemotherapy in advanced and recurrent colorectal cancer (CRC). This study was conducted to assess the risk of TAS-102-induced grade 3 or more neutropenia. Between August 2014 and July 2017, 60 patients underwent oral TAS-102 monotherapy at Ogaki Municipal Hospital, Japan. The patients were divided into two groups based on the development of grade 3 or more neutropenia (9 patients) or not (51 patients). Risk factors for grade 3 or more neutropenia were examined by univariate and multivariate analyses. Creatinine clearance rate (CrCl) before TAS-102 administration significantly correlated with the incidence of Grade 3 or more neutropenia after TAS-102 administration (odds ratio 6.5, 95% confidence interval 1.14-30.00; p = 0.02). Multivariate analysis revealed that a CrCl of lower than 57.1 mL/min before TAS-102 administration (odds ratio 54.06, 95% confidence interval 2.14-1364.2; p = 0.02) was an independent risk factor significantly contributing to the development of grade 3 or more neutropenia, induced by TAS-102. CrCl < 57.1 mL/min in patients with advanced and recurrent CRC who underwent TAS-102 chemotherapy was associated with grade 3 or more neutropenia.

Abstract
This paper introduces noninvasive deep body thermometers suitable for continuous deep body temperature (DBT) measurement. On the basis of their features, they were used in DBT monitoring for daily healthcare. A thermometer based on the dual-heat-flux method (T_DHFM), and an aural canal thermistor (ACT), were used in two studies of daily healthcare. The medical device CoreTemp by Terumo, based on the zero-heat-flux method, was also used for a DBT reference. The first study focused on preventing heat stroke in a high-temperature and high-humidity environment, while the other focused on the temperature monitoring of patients with spinal cord injuries. In the first study, CoreTemp and T_DHFM were used, whereas T_DHFM and ACT were used in the second study. Using the results from these two studies, we discuss the availability and performance of each thermometer and indicate the necessity of an appropriate method of measuring DBT.

Abstract
We implemented an antimicrobial stewardship (AS) program whereby pharmacists sought appropriate use of antimicrobial agents in January 2012. At that time, we targeted anti-methicillin-resistant Staphylococcus aureus (MRSA) agents and carbapenems; however, in January 2014, we added tazobactam/piperacillin (TAZ/PIPC). We evaluated outcomes using multilateral analyses. The average one-day dosage of carbapenems increased; however, the duration of administration and number of recipient patients decreased significantly (P < 0.01). Moreover, the percentage of patients receiving meropenem (MEPM), for whom the time above minimal inhibitory concentration (MIC) was 40% or higher increased (P < 0.01). In contrast, patient utilization of TAZ/PIPC increased significantly after targeting of carbapenems as specific antibacterial agents. However, after TAZ/PIPC was targeted as a specific antibacterial agent, the number of TAZ/PIPC administrations decreased significantly (P < 0.01). The duration of hospitalization and mortality rate in patients receiving specific antibacterial agents significantly decreased after implementation of the AS program (P < 0.01). In conclusion, pharmacist's interventions to provide AS and patient follow-up reduced improper use and promoted proper administration of antibacterial agents. Furthermore, AS was effective in improving patient prognoses and suppressing drug-resistant strains, as well as promoting effective treatment.

Abstract
BACKGROUND/AIM The effect of oral trifluridine-tipiracil (TAS-102)-induced neutropenia on survival of patients with advanced/recurrent colorectal cancer was investigated. PATIENTS AND METHODS Between August 2014 and May 2016, 41 patients underwent TAS-102 monotherapy at Ogaki Municipal Hospital. Risk factors for survival were examined by univariate and multivariate analyses. RESULTS In 41 patients, mild neutropenia (grade 1-2) occurred in 10 patients (24.4%), severe neutropenia (grade 3-4) occurred in 13 (31.7%), and 18 (43.9%) did not experience neutropenia. The median overall survival times in the absent, mild, and severe groups were 120 days (95% confidence interval [CI], 67-179), 184 days (95% CI, 94-274), and 299 days (95% CI, 192-404), respectively (p = 0.045). In patients with severe neutropenia, the death hazard ratio was 0.442 (95% CI, 0.201-0.974; p = 0.042). CONCLUSION In patients with advanced/recurrent colorectal cancer, TAS-102-induced severe neutropenia was associated with superior survival.

Abstract
Thiocarbamate sulfoxides, which are the active forms of thiocarbamate herbicides, are quickly conjugated with glutathione and decomposed in soil. To achieve more potent and stable herbicidal activity, we previously developed a 5-{[(2,6-difluorophenyl)methoxy]methyl}-5-methyl derivative, which has a 4,5-dihydro-1,2-oxazole ring in place of the thiocarbamate to prevent conjugation and decomposition. Although the derivative showed pre-emergence herbicidal activity under flooded conditions, it displayed no herbicidal activity under upland conditions. In contrast, a 5-(methoxymethyl)-5-methyl derivative showed pre-emergence herbicidal activity against grass weeds under upland conditions. The aim of this study was to obtain a more potent compound with improved physicochemical properties for use as a pre-emergence upland herbicide via the structural optimization of a 3-{[(hetero)aryl]methanesulfonyl}-4,5-dihydro-1,2-oxazole as the core structure. In this way, we have developed the pre-emergence herbicide 3-{[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]methanesulfonyl}-5,5-dimethyl-4,5-dihydro-1,2-oxazole, which has been named "pyroxasulfone." This novel compound displayed excellent herbicidal activity against grass and broadleaf weeds under upland conditions with no phytotoxicity against crops.

Abstract
The rhythm of life on earth is shaped by seasonal changes in the environment. Plants and animals show profound annual cycles in physiology, health, morphology, behaviour and demography in response to environmental cues. Seasonal biology impacts ecosystems and agriculture, with consequences for humans and biodiversity. Human populations show robust annual rhythms in health and well-being, and the birth month can have lasting effects that persist throughout life. This review emphasizes the need for a better understanding of seasonal biology against the backdrop of its rapidly progressing disruption through climate change, human lifestyles and other anthropogenic impact. Climate change is modifying annual rhythms to which numerous organisms have adapted, with potential consequences for industries relating to health, ecosystems and food security. Disconcertingly, human lifestyles under artificial conditions of eternal summer provide the most extreme example for disconnect from natural seasons, making humans vulnerable to increased morbidity and mortality. In this review, we introduce scenarios of seasonal disruption, highlight key aspects of seasonal biology and summarize from biomedical, anthropological, veterinary, agricultural and environmental perspectives the recent evidence for seasonal desynchronization between environmental factors and internal rhythms. Because annual rhythms are pervasive across biological systems, they provide a common framework for trans-disciplinary research.

Abstract
This study was retrospectively carried out to compare the efficacy of echinocandins such as micafungin (MCFG) and caspofungin (CPFG) in the treatment of antibiotic-unresponsive febrile patients with hematologic malignancies. A total of 163 patients received either MCFG or CPFG. We evaluated the efficacy of echinocandin against fever decline in all patients. Fever decline, defined as a body temperature of less than 37.5 °C sustained for more than 48 h without scheduled antipyretic medication. Efficacy assessments showed that the incidence of fever decline was not significantly different between the MCFG and CPFG groups (P=0.599). The median number of days from the start of echinocandin administration to fever decline was 5 in both the MCFG and CPFG groups. Multivariate analysis showed that the use of anti-MRSA drugs (HR, 0.64; 95%CI, 0.45-0.90; P=0.011) and a change from echinocandins to voriconazole or liposomal-amphotericin B (HR, 0.50; 95%CI, 0.30-0.74; P<0.001) are significant risk factors for sustained fever. A significant difference (P=0.002) in incidence of fever decline was however associated with differences in the timing of anti-MRSA drug administration. The median number of days from the start of echinocandin administration to fever decline was 5 when administration of the anti-MRSA drug occurred "simultaneously or prior to echinocandin start" and 11 in the "next day or later of echinocandin start" group. In other words, starting anti-MRSA drug treatment after echinocandin treatment is a risk factor. In conclusion, MCFG and CPFG have similar efficacy as empirical antifungal agents in the treatment of antibioticunresponsive febrile patients with hematopoietic malignancies.

Abstract
Neutropenia may develop as an adverse event in patients with multiple myeloma receiving lenalidomide (LEN) plus dexamethasone (DEX) therapy. In the present study, we examined the risk factors associated with grade 3/4 neutropenia during the first cycle of LEN plus DEX therapy. We observed that hemoglobin level (≤ 8.5 g/dl) was a significant risk factor for grade 3/4 neutropenia during the first cycle of therapy (odds ratio: 19.40; 95% confidence interval: 2.68-141.00; p < 0.01). thus, our findings suggest that determining the hemoglobin level could be useful in the risk management for neutropenia in patients receiving LEN plus DEX therapy.

Abstract
We retrospectively studied the safety of trifluridine/tipiracil combination tablet (TAS-102) monotherapy in patients with advanced and recurrent colorectal cancer. Adverse events to TAS-102 monotherapy were observed in 22 out of 23 cases (95.7%). The most frequent adverse events were neutropenia (69.6%), nausea (53.2%), and malaise (30.4%). Treatment was postponed in 54 (59.3%) out of 91 courses, and in 34 (66.7%) of these 54 courses, the delay in treatment was due to bone marrow suppression. Seven patients with peritoneal metastases suffered from nausea, whilst none of the patients without peritoneal metastases had nausea (p = 0.0139). Nausea and vomiting during a previous chemotherapy cycle was significantly associated with nausea after TAS-102 treatment (p = 0.0007), and the treatment cycles were significantly longer in patients with grade 3 or 4 neutropenia (p = 0.0061). Our results suggest that the incidence of nausea was higher in patients treated with TAS-102. Therefore, it is important to inform patients of the risk of these toxicities and to provide enhanced supportive care. Moreover, we recommend that, for patients with repeated treatment postponement due to neutropenia, the dosage should be fixed based on therapeutic efficacy and prognosis.

Abstract
Inappropriate antimicrobial treatment could adversely affect the recovery of patients with aspiration pneumonia. We attempted to identify inappropriate antibacterial treatment and to determine the standard use of anti-methicillin-resistant Staphylococcus aureus (MRSA) drugs in aspiration pneumonia patients with MRSA-positive in sputum. Aspiration pneumonia patients with MRSA-positive sputum treated between January 2013 and May 2013 were included in this study to determine the risk factors for death during hospitalization. The relationship between anti-MRSA medicine use and death during hospitalization was also investigated. More than 10⁷ MRSA colony-forming units in sputum culture, creatinine clearance of less than 30 mL/min, and quinolone use were found to be risk factors for death during hospitalization. The death rate during hospitalization was significantly lower in cases a Geckler classification of 4 or 5 when anti-MRSA treatment was initiated soon after the culture was obtained. Therefore, we concluded that the use of quinolones as antibacterial treatment in aspiration pneumonia patients with MRSA-positive sputum should be avoided and that anti-MRSA treatment should be started in cases with good quality sputum cultures.
