Abstract
BACKGROUND In the EV-301 trial, enfortumab vedotin prolonged survival in patients with locally advanced or metastatic urothelial carcinoma previously treated with platinum-based therapy and programmed cell death 1/programmed death-ligand 1 inhibitor. However, real-world Asian data are limited, and potential prognostic markers are non-existent. We aimed to investigate potential prognostic markers for enfortumab vedotin therapy in Asian patients. METHODS We retrospectively enrolled 61 Japanese patients treated with enfortumab vedotin therapy at our hospital and affiliated hospitals between January 2019 and September 2023. RESULTS Enrolled patients (38 men, 23 women; median age 74 [IQR: 68-79] years) had bladder cancer (26 patients) or upper-tract urothelial carcinoma (35 patients). Fifty-four patients reported adverse events (grade >3 in 12). Skin disorders, pruritus, and neuropathy were common adverse effects. The median overall survival was 17.1 months (95% confidence interval: 10.0-not applicable). In multivariate analysis, the C-reactive protein level was an independent marker predicting favorable overall survival with enfortumab vedotin. Patient characteristics did not differ between C-reactive protein-high and -low groups. CONCLUSIONS Our study provides real-world data showing that enfortumab vedotin prolonged survival in Asian patients similar to the EV-301 trial. Additionally, the C-reactive protein level might be considered a prognostic marker of enfortumab vedotin therapy in such patients.

Abstract
Osteoporosis treatment plays a crucial role in preventing fractures, particularly in bedridden patients. We conducted a questionnaire survey presenting hypothetical clinical cases in 2015 and 2020 to investigate trends over a 5-year period. The target population included physicians working in clinics and hospitals within our neighbourhood. The cases were presented, and the questionnaire was administered in a confidential format. The orthopaedic surgeons were matched for age and practice, resulting in 74 cases being included in the analysis. Comparing the 2015 and 2020 results, we observed a notable increase in physicians who would perform "bone mineral density measurements of the lumbar spine and hip." Furthermore, there was a significant rise in the percentage of respondents willing to test for bone metabolic markers, such as serum type I collagen cross-linked N-telopeptide (NTX), procollagen I N-terminal propeptide (P1NP), and tartrate-resistant acid phosphatase 5b (TRACP-5b). Regarding therapeutic agents, bisphosphonates decreased in usage, whereas parathyroid hormone and romosozumab witnessed an increase. In conclusion, the percentage of physicians requesting bone mineral density measurements of the lumbar spine and hip increased over the five-year period. In addition, more physicians chose to utilise bone metabolic markers due to their ease of measurement through blood tests and reduced diurnal variation. Finally, there was a marked trend towards the administration of drugs capable of rapidly and effectively increasing bone mineral density at an early stage of treatment.

Abstract
Objectives At our hospital, prehabilitation has been provided to patients undergoing esophageal cancer surgery since October 2019. This study explored the effects of prehabilitation based on the accumulated database of these patients. Methods This retrospective cohort study included 621 patients who underwent thoracoscopic subtotal esophagectomy. Multiple linear regression analysis was performed using postoperative hospital stay as the objective variable and age, sex, body mass index (BMI), preoperative ventilatory impairment, left ventricular ejection fraction, preoperative hemoglobin A1c, clinical stage, histological type, operative time, surgical blood loss, postoperative complications, and prehabilitation as explanatory variables. We also performed a multivariate analysis in the subgroup of patients who developed postoperative complications and adjusted for possible confounding factors. Postoperative complications and postoperative hospital stay were compared between patients without (n=416) and with (n=205) prehabilitation. Results Postoperative complications, age, blood loss, BMI, and ventilatory impairment influenced the overall length of hospital stay. When the analysis was restricted to patients with complications, prehabilitation was added to that list of factors as a substitute for BMI. The rate of postoperative complications was not affected by prehabilitation (P=0.1675). The number of hospital days did not change with or without prehabilitation in the overall population, but when restricted to patients with complications, the number of hospital days was significantly decreased in the prehabilitation group (P=0.0328). Conclusions Prehabilitation as a perioperative approach has the potential to reduce the postoperative length of hospital stay in patients undergoing esophageal cancer surgery, and active intervention is recommended.

Abstract
BACKGROUND Aging is associated with muscle atrophy, as typified by sarcopenia. Loss of abdominal muscle strength can cause abdominal wall laxity. The purpose of this study was to investigate the relationship between the sacral vertebra-abdominal wall distance (SAD) and movement performance using a simple lateral spine X-ray image for measuring the SAD. METHODS In this retrospective study, we included women aged ≥ 65 years who were attending the outpatient clinic for osteoporosis at our hospital. A total of 287 patients (mean age ± SD, 76.8 ± 7.1 years) with measured SAD were included in the analysis. Patients were divided into two groups based on SAD cutoff (160 mm) and age (75 years), respectively. The patients were examined using the two-foot 20 cm rise test, 3 m Timed Up and Go (TUG) test, two-step test, open-eyed one-leg standing time, and spinal alignment. Normally distributed data are expressed as means (standard deviations) and non-normally distributed data as medians (interquartile range), depending on the results of the Kolmogorov-Smirnov test. Student's t-test and χ2 test were used for between-group comparisons. Regression analysis was performed with SAD as the objective variable. A two-sided p < 0.05 was considered statistically significant. RESULTS The shorter SAD group performed better in the two-step test, TUG test, and open-eyed one-leg standing time (p < 0.001) as well as in the two-foot 20 cm rise test (p < 0.01) compared to the longer SAD group. Spinal alignment was better in the shorter SAD group than in the longer SAD group, with a shorter sagittal vertical axis (p < 0.001), smaller pelvic tilt (p < 0.001), and greater sacral slope (p < 0.05). CONCLUSION SAD was associated with posterior pelvic tilt and movement performance parameters. In addition to testing for osteoporosis, movement performance parameters should be evaluated in women with osteoporosis who are aged ≥ 65 and have greater SAD (≥ 160 mm in this study). The SAD is a new assessment method, and further research is required to verify its validity and reproducibility. This is the first attempt to determine how age and SAD affect movement performance in older adults.

Abstract
We elucidated the efficacy of gut microbiome-altering drugs on pembrolizumab efficacy in patients with metastatic urothelial carcinoma (mUC). Clinical data were analyzed retrospectively from 133 patients with mUC who received second-line pembrolizumab therapy between January 2018 and January 2021, following failed platinum-based chemotherapy. We evaluated the effects of gut microbiome-altering drugs (proton pump inhibitors [PPI]/potassium-competitive acid blockers [P-CAB], H2 blockers, antibiotics, non-steroidal anti-inflammatory drugs [NSAIDs], metformin, antipsychotics, steroids, and opioids), taken by patients within 30 days before/after pembrolizumab treatment, on progression-free survival (PFS) and overall survival (OS). Fifty-one patients received PPI/P-CAB (37/14, respectively); H2 blockers, 7; antibiotics, 35; NSAIDs, 22; antipsychotics, 8; metformin, 3; steroids, 11; and opioids, 29. Kaplan-Meier curves revealed PPI or P-CAB users showed shorter PFS than non-PPI-P-CAB users (p = 0.001, p = 0.005, respectively). Multivariate analysis highlighted PPI/P-CAB use as the only independent prognostic factor for disease progression (hazards ratio: 1.71, 95% confidence interval: 1.14-2.07, p = 0.010) but not death (p = 0.177). Proton pump inhibitors/potassium-competitive acid blockers may decrease the efficacy of pembrolizumab therapy for mUC, possibly via gut microbiome modulation.

Abstract
BACKGROUND The actual changes in biological and physiological parameters during walking are little understood in multiple aspects. OBJECTIVE The objective of this paper was to examine and link the disparate measures of motor, vision, and brain activity for elderly and young adults. METHOD The participants were 15 elderly adults and 10 young adults. Accelerometry, eye tracking, and prefrontal cortex (PFC) activity in the functional near-infrared spectroscopy (fNIRS) were used to evaluate the participants in a 10-m walking test. RESULT The results for the elderly adults were 1) low variabilities of velocity and acceleration along the front-back and up-down axes, 2) a wider gaze range on the right-left axis than the young adults, 3) a high mean PFC activity, and 4) a larger number of high-relation pairs than the young adults for the correlation coefficients of both gait vs. gaze and gait vs. PFC activity. The variabilities of velocity and acceleration, gaze and PFC activity changes for the young adults were selective. CONCLUSION Measuring 10-m walking in a polymetric approach may capture some indicators related to physical and cognitive difficulties such as frailty and dementia.

Abstract
AIMS This study aimed to investigate whether pathways involving transient receptor potential ankyrin 1 (TRPA1) channels in the urinary bladder mediate the bladder overactivity elicited by exposure to a low temperature in rats. METHODS At postnatal week 10, female Sprague-Dawley (SD) rats were intraperitoneally injected with the TRPA1 channel antagonist, HC030031, at room temperature (RT) and subsequently exposed to low temperature (LT). Bladder specimens treated with HC030031 were evaluated for contractions through cumulative addition of the TRPA1 channel agonist trans-cinnamaldehyde. Two days before cystometric investigation, small interfering RNA (siRNA) targeting TRPA1 was transfected into urinary bladders. Then, cystometric investigations were performed on rats subjected to TRPA1 siRNA transfection at both RT and LT. Expression of TRPA1 channels in the urinary bladder was assessed through immunohistochemistry and real-time reverse transcription-polymerase chain reaction. RESULTS At RT, micturition patterns were unaffected by HC030031 treatment. However, upon exposure to LT, rats treated with HC030031 exhibited a reduction of LT-elicited bladder overactivity, as evidenced by inhibited decreases in voiding interval, micturition volume, and bladder capacity. Additionally, HC030031 inhibited trans-cinnamaldehyde-induced contractions. Immunohistochemical analysis showed the presence of TRPA1 channels in the urinary bladder. Notably, rats with TRPA1 siRNA-transfected bladders could partially inhibit bladder overactivity during LT exposure. CONCLUSIONS These findings indicate that pathways involving TRPA1 channels expressed in the urinary bladder could mediate the LT-elicited bladder overactivity.

Abstract
OBJECTIVE Athletic performance can be enhanced immediately after an isometric warm-up, a phenomenon termed post-activation performance enhancement (PAPE). While isometric warm-ups can improve lower extremity sprint and jump performance, neck-specific isometric warm-ups need development and validation for mild traumatic brain disorders and neck pain. This study examined acute effects of isometric warm-ups on neck performance and morphology. METHODS Arm 1: Twenty-six adults (13 M:13F) completed neck performance testing before and after a 10-minute neck isometric warm-up or stationary bike (sham) between two visits. Testing included visual-motor reaction time, peak force, rate of force development, force steadiness, and force replication/proprioception measured by a 6-axis load cell. An inclinometer assessed range-of-motion. Paired t-tests and two-way ANOVA examined effects of neck/bike warm-up and interaction effects, respectively. Arm 2: 24 adults (11 M:13F) completed ultrasound scans of cervical muscles: before 20-minute rest (sham), and before/after a 5-min neck isometric warm-up. Longus colli cross-sectional area and sternocleidomastoid/upper trapezius thickness and stiffness, and cervical extensors thickness was assessed. One-way ANOVA compared morphological values at sham, before, and after warm-up. Significance was set at p < 0.05. RESULTS Isometric neck warm-up increased rate of force development in flexion (p = 0.022), extension (p = 0.001-0.003), right lateral flexion (p = 0.004-0.032), left lateral flexion (p = 0.005-0.014), while peak force improved only in left lateral flexion (p = 0.032). Lateral flexion range-of-motion increased after neck warm-up (p = 0.003-0.026). Similarly, longus colli cross-sectional area (p = 0.016) and sternocleidomastoid thickness (p = 0.004) increased. CONCLUSIONS Increased neck performance characteristics and morphology are likely due to PAPE effects of isometric neck warm-up. For coaches and athletes, simple isometric contractions could be added to existing warm-ups to reduce prevalence, incidence, and severity of mild traumatic brain injuries and neck pain.

Abstract
In my research life of 35years, growing with IETS as a researcher of in vitro maturation and fertilisation (IVM/IVF) of porcine and cattle oocytes, I suffered from hard times related to solving problems that prevented the progress of my research and conferment of my degrees. Many researchers may have similar problems. Thus, I would like to address a few examples of how I overcame these problems related to IVF and help young researchers with similar troubles. There were four main problems to be solved in my experiments. Problem 1: Establishment of IVF using only defined medium in pigs. Problem 2: Establishment of successful in vitro culture (IVC) of IVM/IVF bovine oocytes in defined medium. Problem 3: Low rate of male pronucleus formation in IVM porcine oocytes after IVF. Problem 4: Sedimentation of Ca2+ in the sperm capacitation solution for IVF in pigs. Problem 1 was solved by a lucky accident, in which a sperm suspension that would have otherwise been discarded happened to be successfully used for IVF in pigs. Problems 2, 3 and 4 were solved by communication with scientists whose fields were different from mine, where similar problems had been solved already. Young researchers are encouraged to transcend the boundaries of their research fields and solve problems by interacting with researchers in different fields. There are many good connections or answers around us that may be effective in resolving the problems that are hindering the progress of pending research.

Abstract
We herein report a 12-year-old boy who presented with a fever, erythematous rash on the cheeks, back pain, and dysphagia. Blood tests revealed increased creatine kinase levels, and muscle ultrasonography (MUS) revealed characteristic fascial thickening in the lumbar paraspinal muscles, where myalgia was prominent. Sarcoplasmic expression of myxovirus-resistant protein A on a muscle biopsy and the presence of anti-nuclear matrix protein 2 (NXP2) antibodies confirmed the diagnosis of dermatomyositis. Prednisolone and intravenous immunoglobulin therapy improved the clinical and laboratory parameters as well as fascial thickening. MUS is useful for evaluating fasciitis associated with anti-NXP2 autoantibodies and monitoring therapeutic efficacy.

Abstract
BACKGROUND The current study tested the hypothesis that urinary angiotensinogen (UAGT) and urinary monocyte chemoattractant protein-1 (UMCP-1) levels provide a specific index of intrarenal renin-angiotensin system (RAS) status and the degree of infiltration of macrophages associated with RAS blockade and immunosuppressant treatment in pediatric patients with chronic glomerulonephritis. METHODS We measured baseline UAGT and UMCP-1 levels to examine the correlation between glomerular injury in 48 pediatric chronic glomerulonephritis patients before treatment. Furthermore, we performed immunohistochemical analysis of angiotensinogen (AGT) and CD68 in 27 pediatric chronic glomerulonephritis patients treated with RAS blockades and immunosuppressants for 2 years. Finally, we examined the effects of angiotensin II (Ang II) on monocyte chemoattractant protein-1 (MCP-1) expression in cultured human mesangial cells (MCs). RESULTS Baseline UAGT and UMCP-1 levels positively correlated with urinary protein levels, scores for mesangial hypercellularity, rate of crescentic formation, and expression levels of AGT and CD68 in renal tissues (p < 0.05). UAGT and UMCP-1 levels were significantly decreased after RAS blockade and immunosuppressant treatment (p < 0.01), which was accompanied by AGT and CD68 (p < 0.01), as well as the magnitude of glomerular injury. Cultured human MCs showed increased MCP-1 messenger ribonucleic acid and protein levels after Ang II treatment (p < 0.01). CONCLUSIONS The data indicates that UAGT and UMCP-1 are useful biomarkers of the degree of glomerular injury during RAS blockade and immunosuppressant treatment in pediatric patients with chronic glomerulonephritis.

Abstract
BACKGROUND Low back pain is a common cause of disability in the US with increasing financial burden on healthcare. A variety of treatment options exist to combat LBP. Home-based therapy is a low-cost option, but there is a lack of data on how it compares to therapy in clinical settings. It was hypothesized that when using artificial intelligence-guided therapy, supervised in-clinic interventions would have a greater influence on patient-reported outcomes and strength than unsupervised, home interventions. METHODS This is a non-randomized controlled trial of 51 patients (28 female, 23 male). The investigation compared an 8-week, core-focused exercise intervention in a Clinic (supervised) versus Home (unsupervised) setting. Outcome variables included measures of strength, performance, and patient-reported outcomes related to function. Generalized linear regression (p < 0.05) was used to evaluate outcomes were evaluated with respect to sex, intervention setting, and time. FINDINGS Male subjects exhibited greater strength (p ≤ 0.02) but not greater patient-reported outcomes (p ≥ 0.30) than females. The Clinic group exhibited slightly greater lateral pull-down strength (p = 0.002), greater eccentric phase range of motion during overhead press (p < 0.01), and shorter concentric phase duration during bench press (p < 0.01) than the Home group. Significance between groups was not observed in any other strength, performance, or patient-reported outcome (p ≥ 0.11). INTERPRETATION A lack of consistent significance indicated that the hypothesis was not supported. AI-guided, telehealth exercise produced comparable outcomes in both home and clinical settings. Telehealth options may offer a lower-cost alternative to clinic-based exercise therapy for patients with nonspecific lower back pain.

Abstract
INTRODUCTION Athletes regularly engage in comprehensive neuromuscular and proprioceptive training (NPT) to prevent musculoskeletal (MSK) injuries. NPT exercises such as movement technique, agility, balance, and posture as well as yoga-based stretching and slow/deep breathing have shown added benefits in psychological and other well-being. This study aimed to examine the effects of NPT on knee sensorimotor characteristics and multi-domain wellness and health scores in active seniors. METHODS Twenty seniors participated in the NPT intervention (15-20min session twice a week for 10 weeks) while the control group did not receive any intervention. All participants completed surveys (general health, frailty, anxiety, stress, mindfulness, optimism, and sleep quality) and laboratory testing before and after intervention. Laboratory testing included frailty tests (grip strength, 4-m walk speed, and calcaneal ultrasound-based bone density) and knee sensorimotor characteristics (peak force, visual-motor reaction time, and force steadiness). RESULTS There was significant increase in general mental health (Short Form 36 Mental Health; p = 0.005) and decrease in stress (Perceived Stress Scale; p = 0.010) and sleep disturbances (Pittsburgh Sleep Quality Index; p = 0.019) post-intervention while no significant changes were observed in the control group (p = 0.310-0.654). Peak knee forces in all directions and some visual-motor reaction time and force steadiness were significantly improved post-intervention only in the experimental group (p = 0.001-0.038). CONCLUSION A simple, yet, comprehensive NPT has potential to improve MSK health as well as various domains of well-being among active seniors.

Abstract
INTRODUCTION This study reports an unusual experience of a mother who may have developed birth-related osteoporosis after each of the births of her two children. PRESENTATION OF CASE A 31-year-old woman presented with lumbar back pain. She had given birth to her first child through vaginal delivery 4 months prior and was breastfeeding. Magnetic resonance imaging showed multiple fresh vertebral fractures, but continued breastfeeding resulted in further loss of bone density. The bone mineral density recovered after weaning. The patient gave birth to a second child three years after the first child's birth. She opted to discontinue breastfeeding after the detection of repeated instances of significant bone loss. No new vertebral fractures have occurred in the 9 years since the patient's initial visit to our clinic. DISCUSSION We describe a case where a mother experienced multiple episodes of rapid bone loss following childbirth. Bone health evaluation at an early stage following childbirth may be effective for preventing future bone fractures. CONCLUSION It is desirable to develop a team and guidelines for treating osteoporosis associated with pregnancy and lactation and for the next pregnancy and delivery.

Abstract
Background Following anterior cruciate ligament (ACL) injury, many athletes that undergo surgery and 6-9 months of rehabilitation struggle to return to sport. Evidence suggests that psychological factors contribute to this failure to return-to-sport. Objective Determine the motor control relationship between thigh musculature motor unit characteristics and psychological readiness to return to sport between ACL-injured and healthy controls. Study design A longitudinal cohort study. Methods Athletes longitudinally completed the ACL Return to Sport after Injury (ACL-RSI) survey and isometric strength measures with a measurement of electromyography (EMG) of the vastus lateralis, vastus medialis, biceps femoris, and semitendinosus. A score cut-off of 61 on the ACL-RSI was used to divide ACL-injured groups. EMG was decomposed to provide each identified motor unit's characteristics (amplitude, average firing rate, etc). Results Data demonstrated increased average firing rate for hamstrings (p<0.001), decreased average firing rate for vastus lateralis (p<0.001) and decreased motor unit size for both the quadriceps and hamstrings at return-to-sport post-ACL reconstruction compared with sex-matched and age-matched healthy controls (p<0.001). Furthermore, there were marked differences in disparate ACL-RSI scores between ACL-injured athletes. Conclusions At return to sport, ACL-injured athletes have major alterations of thigh musculature motor control, with smaller motor units used by those with low ACL-RSI scores. This study uniquely demonstrates objective thigh muscle motor unit characteristics that coincide with subjective reports of psychological readiness. This information will be important to address psychomotor complexes of injury for future rehabilitation protocols.

Abstract
We performed a preliminary study of neutron resonance absorption imaging to investigate the spatial distribution of constituent elements in borosilicate glasses containing simulated high-level radioactive waste, in which elemental inhomogeneities affect the physical and chemical stabilities of the glass. Dips generated by the resonance absorptions of Rh, Pd, Na, Gd, Cs, and Sm were observed in the neutron transmission spectra of the glass samples. The spatial distributions of these elements were obtained from the neutron transmission images at the resonance energies. The distributions of Rh and Pd visualized the sedimentation of these platinum group elements. In contrast, the lanthanides (Gd and Sm) and Cs were uniformly dispersed. These results show that neutron resonance absorption imaging is a promising tool for characterizing borosilicate glasses and investigating the vitrification mechanism of high-level radioactive waste.

Abstract
Background and Objective The prognosis of advanced urothelial carcinoma (aUC) is poor. To date, the gold standard of treatment for patients with aUC has been cisplatin-based chemotherapy. More recently, immune checkpoint inhibitors (ICIs) have been widely used for such patients, which has led to an improvement in their prognosis. In clinical practice, predicting the effectiveness of antitumor drugs or the prognosis of patients is important for making decisions on treatment strategies. Various parameters obtained from blood tests in the pre-ICI era have been adopted for patients in the ICI era. In this review, we summarize the parameters reflecting the status of aUC patients treated with ICIs based on current evidence. Methods We conducted a literature search using PubMed and Google Scholar. The publications chosen were all peer-reviewed journals published over an unlimited time period. Key Content and Findings Numerous inflammatory or nutritional parameters can be obtained from routine blood tests. These reflect malnutrition or systemic inflammation in patients with cancer. As in the pre-ICI era, these parameters are useful for predicting the effectiveness of ICIs and the prognosis of patients treated with ICIs. Conclusions Various parameters are related to systemic inflammation and malnutrition, and are easily obtained from a routine blood test. Using these parameters from various studies as reference points is useful in making decisions on treatment for aUC.

Abstract
Since vertebral kyphosis and abdominal circumference are thought to influence sarcopenia and fall risk in osteoporosis, we evaluated sarcopenia and fall risk in patients with different measurements of abdominal circumference and sagittal longitudinal axis (SVA). In this post hoc study, 227 patients aged 65 years or more who visited an outpatient osteoporosis clinic were included in the analysis. Sarcopenia was determined from lean body mass, grip strength, and walking speed by dual energy X-ray absorptiometry; SVA (median 40 mm) and abdominal circumference (median 80 cm) were compared between the four groups, each divided into two groups. Nutritional management, falls, and fall anxiety scores were also examined. The incidence of sarcopenia was significantly increased in those with abdominal circumference < 80 cm in both the SVA < 40 mm and SVA ≥ 40 mm groups (p < 0.05). Nonetheless, the fall scores of those with SVA < 40 mm were lower than those of individuals with SVA ≥ 40 mm (p < 0.01). Based on the results of this study, SVA and abdominal circumference values may predict the risk of sarcopenia and falls. More research is needed before our results can be translated into clinical practice.

Abstract
BACKGROUND Patients with chronic low back pain can exhibit altered slower gait, poor balance, and lower strength/power, and psychological dysfunctions such as pain catastrophizing and fear of movement. Few studies have investigated the relationships between physical and psychological dysfunctions. This study examined associations between patient-reported outcomes (pain interference, physical function, central sensitization, and kinesiophobia) and physical characteristics (gait, balance, and trunk sensorimotor characteristics). METHODS Laboratory testing included a 4-m walk, balance, and trunk sensorimotor testing with 18 patients and 15 controls. Gait and balance were collected with inertial measurement units. Isokinetic dynamometry measured trunk sensorimotor characteristics. Patient-reported outcomes included PROMIS Pain Interference / Physical Function, Central Sensitization Inventory, and Tampa Scale of Kinesiophobia. Independent t-tests or Mann-Whitney U tests were used to compare between groups. Additionally, Spearman's rank correlation coefficient (rs) established associations between physical and psychological domains, and Fisher z-tests compared correlation coefficient values between groups (significance P < 0.05). FINDINGS The patient group had worse tandem balance and all patient-reported outcomes (P < 0.05) while no group differences were observed in gait and trunk sensorimotor characteristics. There were significant correlations between worse central sensitization and poor tandem balance (rs = 0.446-0.619, P < 0.05) and lower peak force and rate of force development (rs = -0.429-0.702, P < 0.05). INTERPRETATION Observed group differences in tandem balance agree with previous studies, indicating impaired proprioception. The current findings provide preliminary evidence that balance and trunk sensorimotor characteristics were significantly associated with patient-reported outcomes in patients. Early and period screening could help clinicians further categorize patients and develop objective treatment plans.

Abstract
Pesticide reduction is given high priority in the worldwide sustainability agenda. The reduction of pesticide impacts, rather than the reduction of application rates, has become a common criterion for monitoring policy progress. However, simplicity-an essential requirement in improving the applicability of pesticide impact assessment-may distort the accuracy of the evaluation and therefore prevent effective pesticide reduction. Here, we present contrasting results that underscore how the selection of evaluation methods that differ in simplicity affects the assessment results of pesticide reduction strategies. Briefly, we analysed the impact of conversion from conventional to low-input management adopting both a simplified linear-based method and a precise method that includes newly calculated nonlinear approach-based characterization factors for 109 active ingredients (AIs). The two methods were then used to estimate the freshwater ecotoxicity impact of eight rice farms in Japan where both conventional pesticide application and pesticide reduction strategies are practiced. The results show that the simplified method generated anomalies at the farm level through overestimation and underestimation of the individual AI impacts. Patterns that contributed to extreme changes of impact at the farm level were also identified. These findings suggest a strong need for a precise evaluation method for effectively monitoring policy progress at the farm level.

Abstract
Joint trauma induces a presynaptic reflex inhibition termed arthrogenic muscle inhibition (AMI) that prevents complete activation of muscles. Reduced motor unit (MU) output is a hypothesised mechanism for persistent strength deficits. The objective of this study was to determine MU characteristics of thigh musculature and determine how they change with anterior cruciate ligament (ACL) injury compared to healthy controls. A randomised protocol of knee flexion/extension isometric contractions (10-50% maximal voluntary isometric contraction) was performed for each leg with surface EMG 5-pin array electrodes placed on the vastus medialis, vastus lateralis, semitendinosus and biceps femoris. Longitudinal assessments for average rate coding, recruitment thresholds and MU action potentials were acquired at 6-month intervals. With exception of the vastus medialis, all thigh musculature of ACL-injured demonstrated smaller MU action potential peak-to-peak amplitude. For average rate coding, ACL-injured demonstrated lower coding rates than Controls for the quadriceps (p < .05) and higher rates than Controls for the hamstrings (p < .05). These MU characteristics were different from Controls after ACL reconstruction up to 12 months post-surgery, yet maximal strength increased during this time frame. As thigh MU characteristics are known across phases of ACL rehabilitation, future studies can assess these patterns of motor control and their potential to determine risk of re-injury. Further, future rehabilitation can target specific intervention programmes to restore motor control.HighlightsMotor unit strategies of arthrogenic muscle inhibition are characterised for the first time via decomposed EMG.Motor unit deficits of thigh musculature persist throughout all phases of ACL rehabilitation, even after return-to-sport.After ACL injury, motor unit sizes at similar recruitment thresholds were smaller than those of healthy controls.

Abstract
OBJECTIVES Assess the impact of concussion by comparing reaction time, peak force recruitment, and rate of force development of adolescent athletes returning from concussion against age- and sex-matched controls in visual-elicited neck movement. DESIGN Athletes sat secured in a custom-built isometric device with their heads secured in a helmet and attached to a 6-axis load cell. They performed neck flexion, extension, and lateral flexion in response to a visual cue. Three trials in each direction were used for statistical analyses; peak force and rate of force development were normalized against athlete mass. SETTING Laboratory. PARTICIPANTS 26 adolescent/young adult athletes (8F/18M), either recently concussed (and cleared for return to sport) or an age- and sex-matched healthy control. MAIN OUTCOME MEASURES Reaction time, angle, standard deviation of angle, deviation from target angle, peak force, and RFD over 50, 100, 150,and 200 ms of movement were measured for each trial. RESULTS Concussed athletes had decreased normalized peak force (P = 0.008) and rate of force development (P < 0.001-0.007). In neck extension, concussed athletes also had decreased movement precision (P = 0.012). CONCLUSIONS Concussion is associated with alterations of neck biomechanics that decrease overall neck strength.

Abstract
BACKGROUND Low back pain is an extremely prevalent issue with an extensive impact, ranging from decreased quality of life to lost years of productivity. Many interventions have been developed to alleviate chronic lower back pain, yet it remains a widespread problem. The objective of this study was to examine the role of artificial intelligence guided resistance training relative to clinical variables in subjects experiencing lower back pain. METHODS 69 out of 108 enrolled and 92 accrued subjects completed the 8-week intervention. Subjects were randomized into four groups (Control, Training, Clinical, or Combined). The Training cohort received supervised artificial-intelligence-guided core-focused resistance training while the Clinical group received clinical care. The Combined group received both clinical care and artificial-intelligence-guided training and the Control group received no treatment. Participants were evaluated using functional testing and patient-reported outcomes at baseline, 4 weeks, and 8 weeks. FINDINGS In the clinical tests, the Clinical and Combined cohorts showed increased total time for isometric extensor endurance and the Clinical cohort increased total distance traveled in the 6-min walk test at 8 weeks. The Training, Clinical, and Combined groups showed improvements in Patient-reported outcomes after 8 weeks. Most of the significant improvements were only seen at the 8-week evaluation for both the clinical evaluations and Patient-reported outcomes. The Control group did not show significant improvements in any outcome measures. INTERPRETATION The present data indicate that core-focused interventions, including artificial-intelligence-guided moderate-resistance exercise, can increase objective functional outcomes and patient satisfaction using Patient-reported outcomes in individuals with lower back pain.

Abstract
INTRODUCTION AND IMPORTANCE Although corticosteroids are effective for bronchial asthma, they are associated with various side effects, such as osteonecrosis of the femoral head and tibial condyle and osteoporosis. Here, we report a patient who was on corticosteroids for a long period of time due to severe asthma, which was thought to have led to lunate osteonecrosis of both wrist joints. Calcitonin (elcatonin), an osteoporosis drug, was administered to the wrist joint. CASE PRESENTATION Allergy to anesthetics and various non-steroidal anti-inflammatory drugs (NSAIDs) made surgical treatment not possible and pain control difficult. In addition, pain in the wrist joint interfered with activities of daily living (ADLs). When calcitonin was administered intra-articularly into the wrist joint, the pain in the wrist joint was relieved and ADLs were improved. However, the pain-suppressing effect lasted only 1 week, and pain returned to the original state by the second week after treatment. Repeated injections were necessary every 2 weeks. CLINICAL DISCUSSION This is the first report of the effectiveness of intra-articular calcitonin in a patient with osteonecrosis of the lunate. This treatment may be applicable to patients with allergies to anesthesia and NSAIDs. CONCLUSION In the present case, calcitonin administered intra-articularly to the wrist appeared to be effective in pain control for steroid-induced lunate osteonecrosis.

Abstract
PURPOSE This study aimed to analyze a feasible and suitable surgical precautionary preparatory technique. The techniques of double-gloving with hygienic hand wash (DH) and single-gloving with surgical hand wash (SS) were compared for their ability to prevent postoperative infection in robotic and laparoscopic minimally invasive surgeries. MATERIALS AND METHODS A prospective, non-randomized, multicenter study was conducted between January 2016 and June 2020. We divided the robotic and laparoscopic cases into two groups: DH and SS. Data on infectious outcomes were collected. Propensity score matching was performed to control for operative characteristics between the two groups. The primary endpoint was the presence of fever and surgical site infections (SSIs) indicating postoperative infection. RESULTS Among four medical centers, seven surgeons were allocated to either the DH or the SS group. A total of 221 and 251 patients underwent DH and SS, respectively. Propensity score matching, which included 171 cases from each group, showed that the incidence of fever during hospitalization was significantly lower in the DH group than that in the SS group (11.7% vs. 23.4%, p=0.007). Multivariable analysis revealed that DH was associated with a reduced odds ratio for developing postoperative fever during hospitalization (risk ratio: 0.49, p=0.043). No differences were found in SSI before and after hospitalization between the two groups. CONCLUSION DH resulted in less postoperative fever and had a comparable effect in preventing SSIs. This procedure could be an alternative to the SS protocol in some minimally invasive surgeries.

Abstract
Combination therapy for cancer is expected for the synergetic effect of different treatments, and the development of promising carrier materials is demanded for new therapeutics. In this study, nanocomposites including functional nanoparticles (NPs) such as samarium oxide NP for radiotherapy and gadolinium oxide NP as a magnetic resonance imaging agent were synthesized and chemically combined with iron oxide NP-embedded or carbon dot-coating iron oxide NP-embedded carbon nanohorn carriers, where iron oxide NP is a hyperthermia reagent and carbon dot exerts effects on photodynamic/photothermal treatments. These nanocomposites exerted potential for delivery of anticancer drugs (doxorubicin, gemcitabine, and camptothecin) even after being coated with poly(ethylene glycol). The co-delivery of these anticancer drugs played better drug-release efficacy than the independent drug delivery, and the thermal and photothermal procedures enlarged the drug release. Thus, the prepared nanocomposites can be expected as materials to develop advanced medication for combination treatment.

Abstract
Raoultella ornithinolytica (R. ornithinolytica) is a gram-negative rod that was considered related to Klebsiella oxytoca and was classified as R. ornithinolytica in 2001. R. ornithinolytica is known as a histamine-producing bacterium that causes mackerel poisoning. Although only few clinical cases of R. ornithinolytica infection in humans have been reported, the number of diagnosed cases is expected to increase owing to the advancements in identification methods. In the present study, we performed a retrospective analysis of cases of R. ornithinolytica infection detected at our hospital. From September 2019 to July 2021, 62 specimens positive for R. ornithinolytica were obtained after removing duplicates. The clinical courses of these cases were investigated retrospectively based on electronic medical records. Of the 62 specimens, 24 were sputum, 19 were urine, three were stool, six were blood, four were bile, and six were other specimens. All the six blood culture specimens in which R. ornithinolytica was detected were from male patients, and the causative diseases were cholangitis in four cases and complicated pyelonephritis in two cases. Of these, two patients with cholangitis succumbed to death due to the worsening of underlying cancer. Identification of R. ornithinolytica is reportedly difficult, and some instruments may misidentify it as Klebsiella oxytoca. The prognosis of R. ornithinolytica infection has been reported to be good when susceptible drugs are used. However, high mortality rates were also reported despite the use of these drugs, suggesting the need for further investigation of clinical features of R. ornithinolytica infection.

Abstract
INTRODUCTION This study evaluated the prognostic value of a sustained high geriatric nutritional risk index (GNRI) during first-line chemotherapy for patients with metastatic urothelial carcinoma (mUC). METHODS Between January 2018 and February 2022, 123 patients received platinum-based chemotherapy at Nagoya City University Hospital and affiliated institutions. Of these, 118 eligible patients that showed an Eastern Cooperative Oncology Group performance status (ECOG-PS) between 0 and 2 were retrospectively examined. Based on body mass index and serum albumin levels, GNRI was calculated immediately before and after the first primary chemotherapy cycle. Patients were divided into two groups based on GNRI: GNRI sustained 92 in sustainable (n=63), and GNRI < 92 in unsustainable (n=55) groups, respectively. Clinical outcomes were compared. RESULTS No significant differences were noted between the two groups including for age, gender, cycle of first-line treatment, and type of series of sequential treatments after failure of first-line therapy. Median overall survival from the start of first-line chemotherapy was 30.2 months (95% confidence interval [CI]: 20.9-NA) for sustainable and 12.6 months (95% CI: 9.0-21.2) for unsustainable groups, respectively (p < 0.05). Multivariate analysis identified ECOG-PS:2 and fatigue, an adverse event, as independent predictors of unsustainable GNRI transition (95% CI: 1.29-90.6, odds ratio [OR]: 10.8; 95% CI: 1.06-26.9, OR: 5.34, respectively). Conclusion/Conclusion: Sustaining a high level of GNRI was an important prognostic indicator in patients with mUC receiving first-line chemotherapy. Appropriate intervention for controlling adverse events, including fatigue, may enhance physical strength during cancer treatment.

Abstract
Introduction It is well documented that marked weakness of the quadriceps is present after knee joint injury. This joint trauma induces a presynaptic reflex inhibition of musculature surrounding the joint, termed arthrogenic muscle inhibition (AMI). The extent to which anterior cruciate ligament (ACL) injury affects thigh musculature motor unit activity, which may affect restoration of thigh muscle strength after injury, is undetermined. Methods A randomized protocol of knee flexion and extension isometric contractions (10%-50% maximal voluntary isometric contraction) were performed for each leg on 54 subjects with electromyography array electrodes placed on the vastus medialis, vastus lateralis, semitendinosus, and biceps femoris. Longitudinal assessments for motor unit recruitment and average firing rate were acquired at 6-month intervals for 1 year post ACL injury. Results The ACL-injured population demonstrated smaller quadriceps and hamstrings motor unit size (assessed via motor unit action potential peak-to-peak amplitude) and altered firing rate activity in both injured and uninjured limbs compared to healthy controls. Motor unit activity remained altered compared to healthy controls at 12 months post ACL reconstruction (ACLR). Discussion Motor unit activity was altered after ACLR up to 12 months post-surgery. Further research is warranted to optimize rehabilitation interventions that adequately address altered motor unit activity and improve safety and success with return to sport after ACLR. In the interim, evidence based clinical reasoning with a focus on development of muscular strength and power capacity should be the impetus behind rehabilitation programming to address motor control deficits.

Abstract
BACKGROUND The effect of early-term birth on the development of hypoglycaemia in large-for-gestational-age (LGA) neonates is yet to be clarified. This study aimed to clarify the association between hypoglycaemia and early-term birth in LGA neonates. METHODS This single-centre retrospective cohort study evaluated LGA neonates born at term at Tsurugi Municipal Handa Hospital, Japan. Blood glucose levels were measured immediately and at 1, 2, and 4 hours after birth. The association between early-term birth and hypoglycaemia was evaluated using logistic regression analysis. The prevalence of severe hypoglycaemia and hypoglycaemia according to its timing of development was analysed using Fisher's exact test. RESULTS In total, 295 neonates were included. Among them, 113 neonates (38.3%) were born at early term and 91 infants (30.8%) had hypoglycaemia. Logistic regression analysis showed a significant association between early-term birth and hypoglycaemia (adjusted odds ratio [95% confidence interval]:2.691 [1.597 to 4.535]). However, there was no significant between-group difference among those with severe hypoglycaemia. CONCLUSIONS Among LGA neonates, early-term birth is positively associated with neonatal hypoglycaemia. This indicates that among LGA neonates, those born at early term require more careful observation for hypoglycaemia than do those born at later term. J. Med. Invest. 70 : 476-482, August, 2023.

Abstract
Background Previous literature has postulated a relationship between greater hamstring stiffness and a higher risk of sustaining injury. Shear wave elastography (SWE) presents a relatively new means for non-invasive evaluation of soft tissue elasticity pre- and post- injury or intervention. Purpose 1. To establish baseline hamstring stiffness measures for young competitive athletes and (2) determine effect of targeted neuromuscular training (TNMT) on shear wave stiffness of the hamstring. Study Design Un-blinded, prospective, non-randomized, cohort study. Methods Six-hundred forty-two lower extremities from 321 high school and collegiate basketball athletes (177 F: 139 M) were examined for hamstring stiffness prior to the start of their competitive basketball season. Teams were cluster assigned to either the control or intervention (TNMT) group. Subjects in the control group underwent regular season activities as directed, with no influence from the research team. For the TNMT group, the research team introduced a hamstring targeted dynamic warm-up program as an intervention focused on activating the hamstring musculature. Results Collegiate status was significant to hamstring stiffness for both sexes (p ≤ 0.02), but hamstring stiffness did not correlate to age or sex (r2 ≤ 0.08). Intervention was a significant factor to hamstring stiffness when the hip was positioned in extension (p ≤ 0.01), but not in deeper flexion (p = 0.12). This effect was sex-specific as TNMT influenced hamstring stiffness in females (p = 0.03), but not in males (p ≥ 0.13). Control athletes suffered three HAM injuries; TNMT athletes suffered 0 hamstring injuries. Conclusion Higher SWE measurements correlated with increased risk of injury, male sex, and collegiate athletics. TNMT intervention can lessen muscle stiffness which may reduce relate to injury incidence. Intervention effectiveness may be sex specific. Level of Evidence II.

Abstract
Introduction Urethral clear cell carcinoma is rare and often arises from a urethral diverticulum and rarely from the Müllerian duct. However, an explanation for this correlation remains unknown. Case presentation We report the case of a 46-year-old woman who presented with hypermenorrhea. Magnetic resonance imaging revealed a papillary tumor in a cystic lesion in the dorsal urethra. We performed a robot-assisted radical cystourethrectomy and created an ileal conduit. Since pathological findings revealed microvascular and lymphovascular invasions around the urethra, adjuvant radiation therapy was administered. The patient showed no signs of recurrence or metastasis after treatment. Conclusion We report a case of clear cell carcinoma in a female urethral diverticulum originating from a Müllerian duct cyst. While postoperative radiation therapy has been shown to produce a good outcome in carcinoma cases similar to this one, we recommend that a radical cystourethrectomy be performed.

Abstract
Abstract
Background
Right heart failure following left ventricular assist device (LVAD) implantation is a major complication which significantly impairs functional capacity and quality of life (QoL). Right ventricular (RV) reserve function may limit exercise capacity and QoL in LVAD patients; however, most patients show normal RV haemodynamics at rest.
Purpose
The aim of this study was to investigate whether RV reserve assessed by the changes of RV function during exercise is correlated with exercise capacity and QoL in patients with LVAD.
Methods
We prospectively examined 20 consecutive LVAD patients who were admitted to our university hospital between June 2020 and November 2021 after excluding those who were unable to perform exercise (n=8). All patients underwent invasive exercise right heart catheterisation with simultaneous echocardiography in the supine position. RV stroke work index (RVSWI) was calculated as 0.0136 × stroke volume index × (mean pulmonary artery pressure [mPAP] − right atrial pressure [RAP]) at rest and during exercise. Exercise capacity and QoL were assessed by 6-minute walk distance (6MWD) and peak oxygen consumption (VO2) in cardiopulmonary exercise testing, and the EuroQol visual analogue scale (EQ-VAS), respectively. The patients were divided into two groups according to the median ΔRVSWI (RVSWI change from rest to peak exercise) of 1.45 (interquartile range [IQR] −0.31 to 8.25) g/m2.
Results
Patients were predominantly male (75%) and the median age was 47 (IQR 38–60) years. Patients with lower ΔRVSWI had significantly higher change on RAP (P=0.019), but significantly lower change on mPAP (P<0.001) compared to those with higher ΔRVSWI. There were no significant differences in age, gender, primary aetiology of heart failure, type of LVAD devices, or echocardiographic parameters including tricuspid annular plane systolic excursion, and RVSWI at rest between the groups. ΔRVSWI during exercise were positively correlated with 6MWD (R=0.69, P<0.01) and peak VO2 (R=0.66, P<0.01) (Figure A). In addition, ΔRVSWI during exercise were positively correlated with the EQ-VAS (R=0.48, P=0.031). On the other hand, there was no significant correlation between RVSWI at rest and 6MWD (R=−0.11, P=0.63) and peak VO2 (R=0.13, P=0.95), and the EQ-VAS (R=0.11, P=0.61). During a median follow-up period of 312 (IQR 176–369) days, adverse events occurred in 3 patients (15%), including 1 death and 2 hospitalisations for major bleeding and right heart failure. Kaplan-Meier analysis revealed that the adverse events more frequently occurred in patients with lower ΔRVSWI compared to those with higher ΔRVSWI (Figure B).
Conclusions
ΔRVSWI was positively correlated with 6MWD, peak VO2 and EQ-VAS irrespective of RV function at rest. Our findings suggest that the assessment of RV reserve function using ΔRVSWI would be useful for risk stratification in patients with LVAD.

Abstract
INTRODUCTION This study had two objectives: (i) to evaluate oncological outcomes in a long-term follow-up of patients with bladder cancer after reduced port laparoscopic radical cystectomy (RP-LRC); (ii) to assess the effect of modified Glasgow prognostic scores (mGPS) on patient outcomes. METHODS Consecutive patients (n=100) who received RP-LRC between March 2012 and December 2018 at our institution and affiliated hospital were retrospectively reviewed. Preoperative serum albumin and C-reactive protein levels were determined. Patients were grouped based on clinical T stage (≤ cT2: n=75, ≥ cT3: n=25) using pooled cumulative data. Oncological outcomes and mGPS as a prognostic biomarker were analyzed retrospectively. Kaplan-Meier curves displayed recurrence and survival rates. Univariate and multivariate Cox regression analyses evaluated potential prognostic factors for recurrence-free (RFS) and cancer-specific (CSS) survival. RESULTS Patient characteristics between the two groups were statistically similar for preoperative hematological and mGPS status, blood loss level, rate of allogeneic transfusion, and pneumoperitoneum time. After a median follow-up period of 55 months, 40/100 patients experienced disease relapse. RFS and CSS for ≤ cT2 were significantly less than for ≥ cT3 (p<0.001, p<0.05, respectively). Distant metastasis occurred in 30 patients with similar distributions of relapse sites between T-stage cohorts. Median RFS for mGPS 1/2 were 18.9 (95% confidence interval [CI]: 8.8-not assessed [NA]) and 35.0 (95% CI: 8.7-NA) months, respectively, significantly worse than for mGPS 0 (median NA, 95% CI: NA-NA); CSS was similar. Univariate and multivariate analyses revealed ≥ cT3 stage, worse clinical N stage, and poor mGPS status were significant prognostic factors for short RFS and CSS. CONCLUSIONS A large proportion of bladder cancer patients who undergo RP-LRC experience relapse, with ≥ cT3 stage, worse clinical N stage or poor mGPS status identified as significant prognostic factors. Our findings may contribute to improved surgical procedures for such patients.

Abstract
OBJECTIVES In March 2019, cefazolin was unavailable owing to difficulty in procuring the active ingredient. Furthermore, the supply of alternative drugs, such as cefotiam and cefmetazole, was limited. In the Department of Nephro-Urology, fosfomycin-based drugs are used as substitutes for cefazolin, which is a perioperative prophylactic antibacterial drug. Herein, we investigated the effectiveness of fosfomycin sodium and cefotiam in preventing infection after endoscopic combined intrarenal surgery as a retrospective preliminary study. METHODS A total of 200 patients who underwent endoscopic combined intrarenal surgery at our department between August 2017 and January 2021 were included. The patients were administered cefotiam (n = 95) or fosfomycin (n = 105) as perioperative antibacterial agents. There were no significant differences in the median age or surgery time between the cefotiam and fosfomycin groups. Propensity score matching was performed to match the preoperative urine bacterial counts of both groups. Sixty-eight patients were selected from each group. RESULTS The median postoperative hospital stay duration was 4 days for the two groups. The median maximum postoperative temperatures were 37.5 and 37.4°C, respectively. There were no significant differences between the maximum postoperative temperatures in both groups. Furthermore, there were no differences between the groups regarding the white blood cell counts, C-reactive protein levels, and aspartate aminotransferase and alanine aminotransferase levels postoperatively, as well as in terms of postoperative fever requiring additional antibiotics. CONCLUSIONS During a period of difficulty in acquiring cefazolin and cefotiam, the use of fosfomycin allowed us to continue with the procedure without increased clinical complications.

Abstract
Prolactin (PRL), a hormone involved in lactation, is mainly produced and secreted by the lactotrophs of the anterior pituitary (AP) gland. We previously reported a method to generate functional adrenocorticotropic hormone-producing cells by differentiating the AP and hypothalamus simultaneously from human induced pluripotent stem cells (iPSCs). However, PRL-producing cells in the induced AP have not been investigated. Here, we confirmed the presence of PRL-producing cells and evaluated their endocrine functions. We differentiated pituitary cells from human iPSCs using serum-free floating culture of embryoid-like aggregates with quick reaggregation (SFEB-q) method and evaluated the appearance and function of PRL-producing cells. Secretion of PRL from the differentiated aggregates was confirmed, which increased with further culture. Fluorescence immunostaining and immunoelectron microscopy revealed PRL-producing cells and PRL-positive secretory granules, respectively. PRL secretion was promoted by various prolactin secretagogues such as thyrotropin-releasing hormone, vasoactive intestinal peptide, and prolactin-releasing peptide, and inhibited by bromocriptine. Moreover, the presence of tyrosine hydroxylase-positive dopaminergic nerves in the hypothalamic tissue area around the center of the aggregates connecting to PRL-producing cells indicated the possibility of recapitulating PRL regulatory mechanisms through the hypothalamus. In conclusion, we generated pituitary lactotrophs from human iPSCs; these displayed similar secretory responsiveness as human pituitary cells in vivo. In the future, this is expected to be used as a model of human PRL-producing cells for various studies, such as drug discovery, prediction of side effects, and elucidation of tumorigenic mechanisms using disease-specific iPSCs. Furthermore, it may help to develop regenerative medicine for the pituitary gland.

Abstract
We quantitatively evaluated the cumulative ecological risks from multiple pesticides used in paddy fields in Japan. Moreover, we visualized the temporal and regional variability of those risks for 1990-2010. Considering the region-specific parameters of environmental conditions, region-specific predicted environmental concentrations were estimated at 350 river-flow monitoring sites in Japan. Then the multi-substance potentially affected fraction (msPAF) was calculated as a risk index of multiple pesticides by using the computation tool NIAES-CERAP. The median msPAF values for insecticides and herbicides decreased by 92.4% and 53.1%, respectively, from 1990 to 2010. This substantial reduction in ecological risk was attributed to the development of low-risk pesticides by manufacturers, the efforts of farmers in risk reduction, and tighter regulation by the Japanese government. In particular, the substantial reduction of the ecological risk from insecticides was largely due to the decrease in the use of organophosphorus insecticides.

Background
Cardiac power output (CPO) is a measure of cardiac pumping function, and CPO during exercise is known to be a powerful prognostic marker of heart failure. Despite its prognostic significance, pathophysiological mechanism of the association between reduced CPO and worse clinical outcome is unknown. We hypothesized that reduced CPO is associated with worse outcome through the reduced exercise capacity and enhanced ventilatory response.
Methods
Cardiopulmonary exercise testing and exercise stress echocardiography were performed in consecutive 64 patients with chronic heart failure who admitted to our department for the management of heart failure [60 ± 14 years old, left ventricular (LV) ejection fraction 39 ± 16%, ischemic etiology 16%, brain natriuretic peptide 124 pg/ml (51-313)]. Peak oxygen uptake (peak VO2) and the lowest minute ventilation / carbon dioxide production ratio (VE/VCO2) were measured as a parameter of exercise tolerance and that of ventilatory response, respectively. LV ejection fraction was measured by disk summation method at peak exercise. By using Doppler images, E/e" at peak exercise was measured as a marker of LV filling pressure, and CPO normalized by LV mass was obtained as 0.222 × cardiac output × mean blood pressure / LV mass [W/100 g]. Cardiac events defined as hospitalization for heart failure, cardiac death, or implantation of a LV assist device after the examinations were recorded.
Results
CPO at rest was weakly correlated with peak VO2 (r = 0.25, p = 0.046) but not with VE/VCO2. In contrast, CPO at peak exercise was positively correlated with peak VO2 (r = 0.50, p < 0.001) and inversely correlated with VE/VCO2 (r=-0.40, p = 0.002). Moreover, CPO at peak exercise determined both peak VO2 (b = 0.50) and VE/VCO2 (β=-0.54) independently of LV ejection fraction and E/e" at peak exercise. During a median follow-up period of 1211 days, 12 cardiac events were observed. Each of reduced peak VO2 (hazard ratio 0.78, 95% confidence interval 0.66-0.90) and increased VE/VCO2 (hazard ratio 1.10, 95% confidence interval 1.02-1.18) was associated with worse clinical outcome.
Conclusions
In patients with chronic heart failure, CPO during exercise was associated with prognosis of heart failure through the reduced exercise capacity and enhanced ventilatory response.

Abstract
BACKGROUND: The global community is faced with aging societies, which will result in increased health care costs. we have been introducing our International Organization for Standardization (ISO)-certified health education system in Thailand and Indonesia. OBJECTIVE: The purpose of this study was to collect data on the effects of this ISO-certified health education system, to extend the healthy life expectancy and to study the feasibility of implementing this program and in new social contexts. METHODS: We implemented the health education program recruiting 43, 114 and 119 participants, respectively, in Japan, Thailand and Indonesia. The participants’ conditions before and after the program were determined through anthropometry, physical fitness tests, blood chemistry tests, brain function tests and pedometry. RESULTS: Regarding pedometry, the Japanese participants took the highest number of daily steps on average, followed by the Indonesian and Thai participants. In the 10-m obstacle walk, the Thai and Indonesian participants had significantly increased times. Furthermore, the differentiation reaction time, reverse differentiation reaction time, total number of “misses”, total number of “mistakes” and total number of errors significantly improved.

Abstract
Species sensitivity distributions (SSDs) of 38 pesticides with various modes of action were analyzed as a higher-tier ecological effect assessment based on collected acute toxicity data. Then the 5% hazardous concentrations (HC5) based on each SSD were calculated as the predicted no-effect concentrations for aquatic ecosystems. The differences between HC5 and registration criteria were small (within ten-fold) for 35 of the 38 pesticides. However, there were more than ten-fold differences for a fungicide and two herbicides. These results suggest that the current effect assessment scheme could underestimate the effect of such pesticides. This could be caused by differences in sensitivity of specific properties of the mode of action.
