A prospective comparison study utilizing patient-reported outcomes of taxane-related peripheral neuropathy between nab-paclitaxel and standard paclitaxel in patients with breast cancer.

BACKGROUND: Characteristics of taxane-induced peripheral neuropathy (PN) could be different between paclitaxel and nab-paclitaxel. The purpose of this prospective observational multicenter cohort study was to compare tri-weekly nab-paclitaxel to weekly standard paclitaxel regarding the severity, onset and recovery of sensory and motor PN in patients with breast cancer. METHODS: Patients with histologically confirmed breast cancer who were scheduled to receive standard weekly paclitaxel (80 mg/m2) or tri-weekly nab-paclitaxel (260 mg/m2) at institutions in our multicenter group were eligible for this study. Sensory and motor PN were evaluated every 3 weeks until PN improved for up to one year using patient-reported outcome. RESULTS: Between February 2011 and April 2013, 115 patients were enrolled, including 57 and 58 in the paclitaxel and nab-paclitaxel groups, respectively. The incidence of moderate or severe sensory PN was not significantly different between the two groups (p = 0.40). The incidence of moderate or higher motor PN was more frequent in the nab-paclitaxel group than in the paclitaxel group (p = 0.048). The median period for demonstrating PN were shorter in the nab-paclitaxel group than in the paclitaxel group (sensory, p = 0.003; motor, p = 0.001). The recovery of motor PN was slower in the nab-paclitaxel group than in the paclitaxel group (p = 0.035), while the recovery period of sensory PN was not statistically different. CONCLUSION: Nab-paclitaxel induced sensory PN sooner than paclitaxel, and no difference was observed in the severity and recovery duration between the two agents. Motor PN was more severe, started sooner, and improved over a longer period in the nab-paclitaxel-treated patients than in the paclitaxel-treated patients.

Association of D-dimer level with thrombotic events, bleeding, and mortality in Japanese patients with solid tumors: a Cancer-VTE Registry subanalysis.

BACKGROUND: The D-dimer test is a simple test frequently used in routine clinical screening for venous thromboembolism (VTE). The Cancer-VTE Registry was a large-scale, multicenter, prospective, observational study in Japanese patients with cancer. This study aimed to clarify the relationship between D-dimer level at cancer diagnosis (baseline) and the incidence of events during cancer treatment (1-year follow-up period). METHODS: This was a post hoc sub-analysis of patients from the Cancer-VTE Registry whose D-dimer levels were measured at baseline. The incidence of events during the 1-year follow-up period was evaluated stratified by baseline D-dimer level. Adjusted hazard ratios for D-dimer level and events during the follow-up period were evaluated. RESULTS: Among the total enrolled patients, baseline D-dimer level was measured in 9020 patients. The mean ± standard deviation baseline D-dimer level was 1.57 ± 3.94 µg/mL. During the follow-up period, the incidence of VTE, cerebral infarction/transient ischemic attack (TIA)/systemic embolic events (SEE), bleeding, and all-cause death increased with increasing baseline D-dimer level. The incidence of all-cause death increased with increasing D-dimer level regardless of cancer stage. The adjusted hazard ratio of all-cause death was 1.03 (95% confidence interval: 1.02-1.03) per 1.0-µg/mL increase in baseline D-dimer level. CONCLUSIONS: Increases in D-dimer levels were associated with a higher risk of thrombotic events, such as VTE and cerebral infarction/TIA/SEE, during cancer treatment. Furthermore, higher D-dimer levels at cancer diagnosis were associated with a higher mortality rate, regardless of cancer stage.

Comparison of the efficacy and tolerability of elobixibat plus sodium picosulfate with magnesium citrate and split-dose 2-L polyethylene glycol with ascorbic acid for bowel preparation before outpatient colonoscopy: a study protocol for the multicentre, randomised, controlled E-PLUS trial.

BACKGROUND: Sodium picosulfate (SP)/magnesium citrate (MC) and polyethylene glycol (PEG) plus ascorbic acid are recommended by Western guidelines as laxative solutions for bowel preparation. Clinically, SP/MC has a slower post-dose defaecation response than PEG and is perceived as less cleansing; therefore, it is not currently used for major bowel cancer screening preparation. The standard formulation for bowel preparation is PEG; however, a large dose is required, and it has a distinctive flavour that is considered unpleasant. SP/MC requires a small dose and ensures fluid intake because it is administered in another beverage. Therefore, clinical trials have shown that SP/MC is superior to PEG in terms of acceptability. We aim to compare the novel bowel cleansing method (test group) comprising SP/MC with elobixibat hydrate and the standard bowel cleansing method comprising PEG plus ascorbic acid (standard group) for patients preparing for outpatient colonoscopy. METHODS: This phase III, multicentre, single-blind, noninferiority, randomised, controlled, trial has not yet been completed. Patients aged 40-69 years will be included as participants. Patients with a history of abdominal or pelvic surgery, constipation, inflammatory bowel disease, or severe organ dysfunction will be excluded. The target number of research participants is 540 (standard group, 270 cases; test group, 270 cases). The primary endpoint is the degree of bowel cleansing (Boston Bowel Preparation Scale [BBPS] score ≥ 6). The secondary endpoints are patient acceptability, adverse events, polyp/adenoma detection rate, number of polyps/adenomas detected, degree of bowel cleansing according to the BBPS (BBPS score ≥ 8), degree of bowel cleansing according to the Aronchik scale, and bowel cleansing time. DISCUSSION: This trial aims to develop a "patient-first" colon cleansing regimen without the risk of inadequate bowel preparation by using both elobixibat hydrate and SP/MC.

Efficacy of endoscopic submucosal resection with a ligation device for small rectal neuroendocrine tumor: study protocol of a multicenter open-label randomized control trial (BANDIT trial).

BACKGROUND: Endoscopic resection is widely accepted as a local treatment for rectal neuroendocrine tumors sized ≤ 10 mm. However, there is no consensus on the best method for the endoscopic resection of rectal neuroendocrine tumors. As a simplified endoscopic procedure, endoscopic submucosal resection with a ligation device (ESMR-L) indicates a histologically complete resection rate comparable to that of endoscopic submucosal dissection (ESD). We hypothesized that ESMR-L than ESD would be preferred for rectal neuroendocrine tumors. Hence, this trial aimed to verify whether ESMR-L is non-inferior to ESD in terms of histologically complete resection rate. METHODS: This is a prospective, open-label, multicenter, non-inferiority, randomized controlled trial of two parallel groups, conducted at the Shizuoka Cancer Center and 31 other institutions in Japan. Patients with a lesion endoscopically diagnosed as a rectal neuroendocrine tumor ≤ 10 mm are eligible for inclusion. A total of 266 patients will be recruited and randomized to undergo either ESD or ESMR-L. The primary endpoint is the rate of en bloc resection with histologically tumor-free margins (R0 resection). Secondary endpoints include en bloc resection rate, procedure time, adverse events, hospitalization days, total devices and agents cost, adverse event rate between groups with and without resection site closure, outcomes between expert and non-expert endoscopists, and factors associated with R0 resection failure. The sample size is determined based on the assumption that the R0 resection rate will be 95.2% in the ESD group and 95.3% in the ESMR-L group, with a non-inferiority margin of 8%. With a one-sided significance level of 0.05 and a power of 80%, 226 participants are required. Assuming a dropout rate of 15%, 266 patients will be included in this study. DISCUSSION: This is the first multicenter randomized controlled trial comparing ESD and ESMR-L for the R0 resection of rectal neuroendocrine tumors ≤ 10 mm. This will provide valuable information for standardizing endoscopic resection methods for rectal neuroendocrine tumors. TRIAL REGISTRATION: Japan Registry of Clinical Trials, jRCTs042210124.

Incidence and risk factors for venous thromboembolism in the Cancer-VTE Registry pancreatic cancer subcohort.

BACKGROUND: This substudy of the Cancer-VTE Registry estimated venous thromboembolism (VTE) incidence and risk factors in pancreatic cancer patients. METHODS: The Cancer-VTE Registry was an observational study that collected VTE data from patients with solid tumors across Japan. We measured baseline VTE prevalence, and at 1-year follow-up, the cumulative incidence of symptomatic and composite VTE (symptomatic VTE and incidental VTE requiring treatment), bleeding, cerebral infarction/transient ischemic attack (TIA)/systemic embolic event (SEE), and all-cause death. RESULTS: Of 1006 pancreatic cancer patients, 86 (8.5%) had VTE at baseline, and seven (0.7%) had symptomatic VTE. Significant risk factors of baseline VTE were Eastern Cooperative Oncology Group performance status (ECOG PS) of 1, body mass index (BMI) ≥ 25 kg/m2, history of VTE, D-dimer > 1.2 µg/mL, and hemoglobin < 10 g/dL. At 1-year follow-up, the cumulative incidence of events was higher for pancreatic cancer vs other cancers. Pancreatic cancer patients with VTE vs those without VTE had significantly higher incidences of bleeding, cerebral infarction/TIA/SEE, and all-cause death. No significant risk factors for composite VTE were identified. CONCLUSIONS: The cumulative incidence of composite VTE during cancer treatment was higher in pancreatic cancer than in other cancer types. Some risk factors for VTE prevalence at cancer diagnosis were identified. Although VTE prevalence at cancer diagnosis did not predict the subsequent 1-year incidence of composite VTE, it was a significant predictor of other events such as all-cause death in pancreatic cancer patients.

Feasibility Study of Virtual Reality-Based Cognitive Behavioral Therapy for Patients With Depression: Protocol for an Open Trial and Therapeutic Intervention.

BACKGROUND: The clinical usefulness of cognitive behavioral therapy (CBT) for patients with depression who do not remit with pharmacotherapy has been recognized. However, the longer time burden on health care providers associated with conducting CBT and the lack of a system for providing CBT lead to inadequate CBT provision to patients who wish to receive it. OBJECTIVE: We aim to evaluate the feasibility of introducing virtual reality (VR) into CBT for patients with depression. METHODS: This is a single-center, interventional, exploratory, single-arm, nonrandomized, open, pre-post-comparative feasibility study of an unapproved medical device program to evaluate the acceptability, preliminary efficacy, and safety of the study device. Eligible patients meet the diagnostic criteria of the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) for major depressive disorder, have a 17-item Hamilton Depression Rating Scale (HAMD-17) score of ≥12, and are aged 18-65 years. The sample will comprise 12 patients. VR-based CBT (CBT-VR) sessions will be conducted once a week in an outpatient setting. CBT-VR has been developed in accordance with 6 stages and 16 sessions in the current CBT therapist manual. VR contents and other components correspond to the themes of these 16 sessions. The flow of CBT-VR treatment is similar to that of normal CBT; however, this product replaces the in-person portion of CBT. The primary end point will be the change in the HAMD-17 score from baseline up to 16 sessions. Secondary end points will be treatment retention; psychiatrist consultation time; satisfaction with the equipment or program; ease of use; homework compliance; change in the HAMD-17 score from baseline up to 8 sessions; change in Montgomery-Åsberg Depression Rating Scale (MADRS), Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR), EQ-5D-5L, and Clinical Global Impressions (CGI) scores from baseline up to 8 and 16 sessions; and change in remission and response rates and HAMD-17, MADRS, QIDS-SR, and EQ-5D-5L scores from baseline to 3 and 6 months post intervention (or discontinuation). CBT-VR's feasibility will be assessed at baseline, after 8 sessions, after 16 sessions, or treatment discontinuation, by measuring the time required for testing and medical care during each session and with a patient questionnaire. After intervention discontinuation, a follow-up evaluation will be conducted unless the patient withdraws consent or otherwise discontinues participation in the study after 3 and 6 months. RESULTS: Participant recruitment started on November 30, 2022, and data collection is ongoing as of September 2023. CONCLUSIONS: This study is the first step in testing the acceptability, feasibility, and preliminary efficacy and safety of CBT-VR for patients with depression without controls in an open-label trial. If its feasibility for depression treatment is confirmed, we intend to proceed to a large-scale validation study.

Feasibility of a wrist-worn wearable device for estimating mental health status in patients with mental illness.

Object: Real-world data from wearable devices has the potential to understand mental health status in everyday life. We aimed to investigate the feasibility of estimating mental health status using a wrist-worn wearable device (Fitbit Sense) that measures movement using a 3D accelerometer and optical pulse photoplethysmography (PPG). Methods: Participants were 110 patients with mental illnesses from different diagnostic groups. The study was undertaken between 1 October 2020 and 31 March 2021. Participants wore a Fitbit Sense on their wrist and also completed the State-Trait Anxiety Inventory (STAI), Positive and Negative Affect Schedule (PANAS), and EuroQol 5 dimensions 5-level (EQ-5D-5L) during the study period. To determine heart rate (HR) variability (HRV), we calculated the sdnn (standard deviation of the normal-to-normal interval), coefficient of variation of R-R intervals, and mean HR separately for each sleep stage and the daytime. The association between mental health status and HR and HRV was analyzed. Results: The following significant correlations were found in the wake after sleep onset stage within 3 days of mental health status assessment: sdnn, HR and STAI scores, HR and PANAS scores, HR and EQ-5D-5L scores. The association between mental health status and HR and HRV was stronger the closer the temporal distance between mental health status assessment and HR measurement. Conclusion: A wrist-worn wearable device that measures PPG signals was feasible for use with patients with mental illness. Resting state HR and HRV could be used as an objective assessment of mental health status within a few days of measurement.

Impact of renal and hepatic function on first opioid prescriptions in cancer patients: an acute care hospital database study linked to medical claims data and laboratory data.

BACKGROUND: Cancer patients often have impaired renal and hepatic function. Opioids are essential to relieve painful symptoms in cancer patients. However, it is unknown which opioids are first prescribed for cancer patients with renal and hepatic impairment. The objective is to investigate the association between the type of first prescribed opioids and the renal/hepatic function of cancer patients. METHODS: We used a multicenter database from 2010 to 2019. The number of days from the first opioid prescription to the death was defined as the prognostic period. This period was divided into six categories. The prevalence of opioid prescriptions was calculated for each assessment of renal and hepatic function, divided into prognostic periods. Multinomial logistic regression analysis was used to explore the influence of renal and hepatic function on the first opioid choice. RESULTS: The study included 11 945 patients who died of cancer. In all prognostic period categories, the patients with worse renal function received fewer morphine prescriptions. No trend was observed in hepatic function. The odds ratio of oxycodone to morphine with reference to estimated glomerular filtration rate (eGFR) ≥90 was 1.707 (95% confidence interval: 1.433-2.034) for estimated glomerular filtration rate <30. The odds ratio of fentanyl to morphine with reference to estimated glomerular filtration rate ≥90 was 1.785 (95% confidence interval: 1.492-2.134) for estimated glomerular filtration rate <30. No association was identified between hepatic function and the choice of prescribed opioids. CONCLUSION: Cancer patients with renal impairment tended to avoid morphine prescriptions, and no specific trend was observed in cancer patients with hepatic impairment.

Maintenance repetitive transcranial magnetic stimulation (rTMS) therapy for treatment-resistant depression: a study protocol of a multisite, prospective, non-randomized longitudinal study.

BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) is a widely used treatment for major depressive disorder (MDD), and its effectiveness in preventing relapse/recurrence of MDD has been explored. Although few small sample controlled studies exist, the protocols of maintenance rTMS therapy were heterogeneous and evidence of its effectiveness is not sufficient. Thus, this study aims to evaluate whether maintenance rTMS is effective in maintaining the treatment response in patients with MDD with a large sample size and feasible study design. METHODS: In this multicenter open-labelled parallel-group trial we plan to recruit 300 patients with MDD who have responded or remitted to acute rTMS therapy. Participants would be classified into two groups according to their preference; the maintenance rTMS and pharmacotherapy group, and the pharmacotherapy only group. The protocol of maintenance rTMS therapy is once a week for the first six months and once biweekly for the second six months. The primary outcome is the relapse/recurrence rates during 12 months following enrollment. Other measures of depressive symptoms and recurrence/relapse rates at different time points are the secondary outcomes. The primary analysis is the between-group comparison adjusted for background factors using a logistic regression model. We will perform the group comparison with inverse probability of treatment weighting as the sensitivity analysis to ensure the comparability of the two groups. DISCUSSION: We hypothesize that maintenance rTMS therapy could be an effective and safe treatment for preventing depressive relapse/recurrence. Considering the limitation of potential bias owing to the study design, we plan to use statistical approaches and external data to avoid overestimation of the efficacy.

Incidence and risk factors for venous thromboembolism in the Cancer-VTE Registry stomach cancer subcohort.

BACKGROUND: The Cancer-VTE Registry was a large-scale, multicenter, prospective registry designed to investigate real-world data on venous thromboembolism (VTE) incidence and risk factors in adult Japanese patients with solid tumors. This pre-specified subgroup analysis aimed to estimate the incidence of VTE, including VTE types other than symptomatic VTE, and identify risk factors of VTE in stomach cancer from the Cancer-VTE Registry. METHODS: Stage II-IV stomach cancer patients who planned to initiate cancer therapy and underwent VTE screening within 2 months before registration were enrolled. RESULTS: Of 1,896 patients enrolled, 131 (6.9%) had VTE at baseline, but 96.2% were asymptomatic. Female sex, age ≥ 65 years, VTE history, and D-dimer > 1.2 µg/mL were independent risk factors of VTE at baseline. Notably, patients with D-dimer > 1.2 µg/mL at the time of cancer diagnosis had an approximately 20-fold risk of VTE. During follow-up, event incidences were symptomatic VTE, 0.3%; incidental VTE requiring treatment, 1.1%; composite VTE, 1.4%; bleeding, 1.6%; cerebral infarction/transient ischemic attack/systemic embolic events, 0.7%; and all-cause death, 15.0%. The incidence of all-cause death was higher in patients with VTE vs without VTE at baseline (adjusted hazard ratio 1.67; 95% confidence interval 1.21-2.32; p = 0.002). CONCLUSIONS: VTE prevalence at the time of cancer diagnosis was not negligible and was extremely high when the patients had high D-dimer. VTE screening by D-dimer before starting cancer treatment is advisable, even for asymptomatic patients, regardless of whether the patient is undergoing surgery or chemotherapy.

Venous thromboembolism in Japanese patients with breast cancer: subgroup analysis of the Cancer-VTE Registry.

BACKGROUND: This subgroup analysis of the Cancer-VTE Registry, a nationwide, large-scale, multicenter observational study with a 1-year follow-up, assessed real-world data on venous thromboembolism (VTE) among Japanese patients with breast cancer. METHODS: Patients with stage II-IV pretreatment breast cancer screened for VTE at enrollment were included. During the 1-year follow-up period, incidences of VTE, bleeding, and all-cause death, and background factors associated with VTE risk were examined. RESULTS: Of 9,630 patients in the Cancer-VTE Registry analysis set, 993 (10.3%) had breast cancer (973 [98.0%] did not have and 20 [2.0%] had VTE at baseline). The mean age was 58.4 years, 73.4% of patients had stage II cancer, and 94.8% had an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0. Risk factors for VTE at baseline by univariable analysis were age ≥ 65 years, ECOG PS of 2, VTE history, and D-dimer > 1.2 µg/mL. During follow-up, the incidence of symptomatic VTE was 0.4%; incidental VTE requiring treatment, 0.1%; composite VTE (symptomatic VTE and incidental VTE requiring treatment), 0.5%; bleeding, 0.2%; cerebral infarction/transient ischemic attack/systemic embolic event, 0.2%; and all-cause death, 2.1%. One patient with symptomatic VTE developed pulmonary embolism (PE) and died. Incidences of VTE and all-cause death were higher in patients with VTE vs without VTE at baseline. CONCLUSIONS: In Japanese patients with breast cancer, VTE screening before initiating cancer treatment revealed a 2.0% prevalence of VTE. During follow-up, one patient had a fatal outcome due to PE, but the incidences of VTE were low.

Fulvestrant plus palbociclib in advanced or metastatic hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer after fulvestrant monotherapy: Japan Breast Cancer Research Group-M07 (FUTURE trial).

PURPOSE: The combination of cyclin-dependent kinase 4/6 inhibitors and endocrine therapy is a standard treatment for hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (MBC); however, their toxicities and financial burden are major issues, especially for prolonged treatment. We investigated fulvestrant plus palbociclib in patients with HR-positive MBC resistant to fulvestrant monotherapy. METHODS: Patients who initially received fulvestrant as their first- or second-line endocrine therapy were assigned to group A. Patients with disease progression during fulvestrant monotherapy who subsequently received fulvestrant plus palbociclib were assigned to group B. The primary endpoint was progression-free survival (PFS1) in group B. We set the threshold median PFS of 5 months (null hypothesis). RESULTS: Between January 2018 and February 2020 we enrolled 167 patients in group A (January 2018-February 2020) from 55 institutions, of whom 72 subsequently received fulvestrant plus palbociclib and were enrolled in group B. The median follow-up was 23.8 and 8.9 months in groups A and B, respectively. The median PFS in group B (combination therapy) was 9.4 (90% confidence interval [CI]: 6.9-11.2) months (p < 0.001). This was 25.7 (90% CI: 21.2-30.3) months in group A (fulvestrant monotherapy). The TTF in group B was 7.2 (90% CI: 5.5-10.4) months. In the post-hoc analysis, the median PFS1 in group B among patients with longer-duration fulvestrant monotherapy (> 1 year) was longer than that of patients with shorter-duration monotherapy (≤ 1 year) (11.3 vs. 7.6 months). No new toxicities were observed. CONCLUSION: Our findings suggest that palbociclib plus fulvestrant after disease progression despite fulvestrant monotherapy is potentially safe and effective in patients with HR-positive/HER2-negative advanced MBC.

Survival advantage of locoregional and systemic therapy in oligometastatic breast cancer: an international retrospective cohort study (OLIGO-BC1).

BACKGROUND: An international retrospective cohort study was conducted to clarify the survival advantage of combination therapy with locoregional and systemic therapy (ST) in oligometastatic breast cancer (BC). METHODS: Patients with oligometastatic BC diagnosed from 2007 to 2012 were enrolled in center hospitals in China, Korea and Japan. It was defined as a low-volume metastatic disease at up to five sites and not necessarily in the same organ. Cases with brain, pleural, peritoneal and pericardial metastases were excluded. The primary endpoint was overall survival (OS) from the initial diagnosis of oligometastases. OS was summarized using the Kaplan-Meier method. A multivariable Cox regression model was used to estimate the hazard ratio (HR) for clinicopathological factors. RESULTS: Among 1,295 cases registered from February 2018 to May 2019, 932 remained for analysis after the exclusion of unavailable cases and locoregional recurrence. One metastatic site was found in 400 cases, 2 in 243, 3 in 130, 4 in 86 and 5 in 73. At the median follow-up of 4.5 years, 5-year OS was 54.7% and 39.7% for 321 cases in the combination therapy group and 611 cases in the ST group, respectively. An adjusted HR was 0.66 (95% confidence interval: 0.55, 0.79). Some types of ST without chemotherapy alone, younger age, ECOG performance status 0, early-stage BC, non-triple negative subtype, fewer metastatic sites and longer duration of surgery to relapse were significantly favorable prognostic factors. CONCLUSION: Combination therapy may be considered for longer survival under some conditions in oligometastatic BC.

Muscle impairment in MRI affect variability in treatment response to nusinersen in patients with spinal muscular atrophy type 2 and 3: A retrospective cohort study.

BACKGROUND: Real-world data have shown variability in treatment responses to nusinersen in spinal muscular atrophy (SMA). We investigated whether the magnitude of muscle impairment assessed by magnetic resonance imaging (MRI) at baseline can predict the treatment response. METHODS: We retrospectively assessed the clinical data in relevance to the thigh and pelvic MRI taken before the nusinersen treatment. A total of 16 patients with SMA types 2 and 3 (age = mean [SD]; 9.2 [4.6] year) receiving nusinersen treatment were enrolled. The T1-weighted MRI images of the pelvis and thigh were scored for muscle fatty infiltration and atrophy. The minimally clinically important difference (MCID) was considered as gaining at least 3 points of Hammersmith Functional Motor Scale-Expanded (HFMSE) from baseline. RESULTS: Of these 16 individuals, 14 had been treated for at least 15 months with baseline data. At 15 months, seven individuals obtained MCID in HFMSE. Baseline muscle MRI score could not differentiate the two groups; however, individuals who obtained MCID had significantly less severe scoliosis. In addition, there was a significant and negative relationship between baseline MRI score and the change of score in HFMSE after 15 months of treatment. Further, baseline Cobb angle along with MRI score also indicated the correlation to the degree of change in motor function. CONCLUSION: The degree of muscle damage may confer the variability in response to nusinersen in SMA types 2 and 3. Muscle MRI score along with the severity of scoliosis assessed at baseline may help to predict the motor function change.

Valuable interaction with cognitive remediation and optimal antipsychotics for recovery in schizophrenia (VICTORY-S): study protocol for an interventional, open-label, randomized comparison of combined treatment with cognitive remediation and lurasidone or paliperidone.

Background: Cognitive impairment, a core feature of schizophrenia, is associated with poor outcomes. Pharmacotherapy and psychosocial treatment, when used alone, have inadequate effect sizes for cognitive impairment, leading to recent interest in combination interventions. A previous study examined the additive effect of cognitive remediation on lurasidone in patients with schizophrenia, which was negative. Although improvement in cognitive function was suggested for lurasidone, it was inconclusive because there was no antipsychotic control in the study. To clarify whether lurasidone has a meaningful impact on cognitive function in combination with cognitive remediation, we use paliperidone as a control antipsychotic in this study. We hypothesize that combination with lurasidone will improve cognitive and social function to a greater extent than paliperidone. Methods: The valuable interaction with cognitive remediation and optimal antipsychotics for recovery in schizophrenia study is a multicenter, interventional, open-label, rater-blind, randomized comparison study, comparing the effect of lurasidone plus cognitive remediation with that of paliperidone plus cognitive remediation in patients with schizophrenia. The Neuropsychological Educational Approach to Remediation (NEAR) is used for cognitive remediation. Eligible patients will be randomized 1:1 to receive lurasidone or paliperidone combined with NEAR (6 weeks antipsychotic alone followed by 24 weeks combination antipsychotic plus NEAR). The primary endpoint is the change from baseline in the tablet-based Brief Assessment of Cognition in Schizophrenia composite T-score at the end of the NEAR combination treatment period. Secondary endpoints will include change from baseline in social function, schizophrenia symptoms, and quality of life at the end of the NEAR combination treatment period. Furthermore, change from baseline to the end of the pharmacotherapy period and change from the end of the pharmacotherapy period to the end of the NEAR combination treatment period will be assessed for all endpoints. Safety will also be evaluated. Discussion: Achievement of adequate cognitive function is central to supporting social function, which is a key treatment goal for patients with schizophrenia. We think this study will fill in the gaps of the previous study and provide useful information regarding treatment decisions for patients with schizophrenia.

Maternal Metals Exposure and Infant Weight Trajectory: The Japan Environment and Children's Study (JECS).

BACKGROUND: To our knowledge, the association of maternal exposure to metallic elements with weight trajectory pattern from the neonatal period has not been investigated. OBJECTIVES: The goals of this study were to identify infant growth trajectories in weight in the first 3 y of life and to determine the associations of maternal blood levels of lead, cadmium, mercury, selenium, and manganese with growth trajectory. METHODS: This longitudinal study, part of the Japan Environment and Children Study, enrolled 103,099 pregnant women at 15 Regional Centres across Japan between 2011 and 2014. Lead, cadmium, mercury, selenium, and manganese levels were measured in blood samples collected in the second (14-27 wk gestational age) or third trimester (≥28wk). Growth trajectory of 99,014 children was followed until age 3 y. Raw weight values were transformed to age- and sex-specific weight standard deviation (SD) scores, and latent-class group-based trajectory models were estimated to determine weight trajectories. Associations between maternal metallic element levels and weight trajectory were examined using multinomial logistic regression models after confounder adjustment. RESULTS: We identified 5 trajectory patterns based on weight SD score: 4.74% of infants were classified in Group I, very small to small; 31.26% in Group II, moderately small; 21.91% in Group III, moderately small to moderately large; 28.06% in Group IV, moderately large to normal; and 14.03% in Group V, moderately large to large. On multinomial logistic regression, higher maternal lead and selenium levels tended to be associated with increased odds ratios (ORs) of poor weight SD score trajectories (Groups I and II), in comparison with Group III. Higher levels of mercury were associated with decreased ORs, whereas higher levels of manganese were associated with increased ORs of "moderately large" trajectories (Groups IV and V). DISCUSSION: Maternal lead, mercury, selenium, and manganese blood levels affect infant growth trajectory pattern in the first 3 y of life. https://doi.org/10.1289/EHP10321.

Systematic review and meta-analysis of reports of patients with gastric cancer aged 80 years and older.

The number of elderly patients in gastric cancer surgery is rapidly rising. Almost all data on gastric cancer in people over the age of 80 come from a single institution, and there is no systematic review of a large number of patients. Therefore, we conducted a comprehensive analysis of the prognosis of patients with gastric cancer surgery who were aged 80 years or older. From January 2010 to November 2021, reports on gastric cancer in the elderly aged 80 and over were gathered. We searched PubMed for "Gastric cancer and elderly and 80 years old" as a keyword, and 253 reports were extracted. The Ichushi-Web database was also searched using the phrase "stomach cancer and 80 years old," and 366 records were found. The random-effect model was used to determine the average 5-year survival rate, and the heterogeneity was evaluated. The proportion of male patients, patients who had surgery after 2010, patients with stage I, total gastrectomy, lymph node dissection, and the presence of complications were used as the explanatory variables in meta-regressions to investigate the cause of prognosis variability. More than 50 surgical cases were reported, 8 from PubMed and 2 from the Ichushi-Web database, with information on surgical procedures, prognosis, and complications, in a total of 1182 patients. Of the ten reports, eight were from Japan and two were from South Korea and Taiwan. The number of patients ranged from 55 to 217, with an average 5-year survival rate of 57%. In terms of the relationship between the time of surgery and prognosis, the overall prognosis for patients who had surgery before 2010 and those who had surgery after 2010 was almost similar. Reports with a high proportion of stage I showed a good prognosis. The rate of total gastrectomy, the proportion of lymph node dissection above D1 + , or surgical complications had no effect on prognosis. Patients with gastric cancer aged 80 years or older who underwent radical surgery had a 5-year survival rate of up to 57%. Postoperative complications appeared to have a minor impact.

One-Year Incidences of Venous Thromboembolism, Bleeding, and Death in Patients With Lung Cancer (Cancer-VTE Subanalysis).

Introduction: This subanalysis aimed to provide real-world data on venous thromboembolism (VTE) from patients with lung cancer in the Cancer-VTE Registry. Methods: The primary outcome was the number of baseline VTE events in patients with lung cancer. The 1-year cumulative incidences of symptomatic VTE; composite VTE (symptomatic and incidental VTE requiring treatment); bleeding; cerebral infarction, transient ischemic attack, and systemic embolic events; and all-cause death were calculated. Clinical trial registration: UMIN000024942. Results: The study enrolled a total of 2377 patients with lung cancer; of these, 119 (5.0%) had VTE (six [0.3%], symptomatic, and 113 [4.8%], asymptomatic) and 14 (0.6%) had pulmonary embolism at baseline. During the follow-up period (mean, 337.7 d), the incidence was 0.6% for symptomatic VTE, 1.8% for composite VTE, 1.5% for bleeding events, 1.3% for cerebral infarction, transient ischemic attack, and systemic embolism, and 19.1% for all-cause death. Composite VTE frequency did not vary by anticancer drug type. Patients with (versus without) VTE at baseline had higher hazard ratios (HRs) for composite VTE (unadjusted HR: 5.29; Gray test p < 0.001) and symptomatic VTE (unadjusted HR: 4.89; Gray test p = 0.007). Patients with VTE at baseline had higher HRs for bleeding events (unadjusted HR: 3.27; Gray test p = 0.010) and all-cause death (unadjusted HR: 2.73; log-rank test p < 0.001) than patients without. In multivariable analysis, patients with baseline VTE prevalence and Eastern Cooperative Oncology Group Performance Status of 2 had increased composite VTE risk during cancer therapy. There were no other risk factors for composite VTE. Conclusions: Our findings emphasize the importance of VTE screening at cancer diagnosis.

Incidence and risk factors for venous thromboembolism, bleeding, and death in colorectal cancer (Cancer-VTE Registry).

The impact of venous thromboembolism in Japanese colorectal cancer patients has not been elucidated. This prespecified subanalysis of the Cancer-VTE Registry aimed to report venous thromboembolism and event data after 1 year of follow-up in 2477 patients with colorectal cancer and investigate risk factors of venous thromboembolism. Of 2477 patients, 158 (6.4%) had venous thromboembolism in venous thromboembolism screening at enrollment. Asymptomatic distal deep-vein thrombosis accounted for 123/158 (77.8%) of venous thromboembolism cases. During the follow-up period, symptomatic, incidental events requiring treatment and composite venous thromboembolism incidences were 0.3%, 0.8%, and 1.0%, respectively. The incidence of bleeding events, cerebral infarction/transient ischemic attack/systemic embolic event, and all-cause death were 1.0%, 0.3%, and 4.8%, respectively. These results were consistent with the main study results. In multivariable analysis, venous thromboembolism at baseline was a risk factor of composite venous thromboembolism during the follow-up period. Japanese patients with colorectal cancer and advancing cancer stage before treatment had more frequent venous thromboembolism complications at baseline, higher incidence of venous thromboembolism events during cancer treatment, and higher mortality.

Trends in strong opioid prescription for cancer patients in Japan from 2010 to 2019: an analysis with large medical claims data.

BACKGROUND: Consumption of opioids, essential drugs for pain relief, has seen rapid growth worldwide. In Japan, where total opioid consumption still remains low among developed countries, little is known about trends in the clinical patterns of opioids in terminally ill cancer patients. METHODS: Patients who died of cancer from 2010 to 2019 were included in this study. Morphine, oxycodone, fentanyl, tapentadol, methadone and hydromorphone were examined as opioids for cancer pain. We calculated the prevalence of prescribed opioids prior to death by year and age group and the average opioid dose 30 days before death. RESULTS: The total number of patients was 221 598. We found that the prescription prevalence of opioids increased from 60.8 to 65.9% (5.1%). Morphine was most prescribed in 2010 but had decreased prevalence (-9.0%) during the 10-year period. Oxycodone had the highest increase in prescription prevalence (13.7%), and fentanyl prevalence decreased (-4.9%). In the subgroup comparison, the prescription prevalence of opioids in the elderly was lower than that in the younger group; however, the increasing trend in the elderly was greater than that in the younger group. The percentage of patients prescribed low-dose opioids (<60 mg/day) during the 30 days before death increased by 4.9% and was the highest throughout the study period. CONCLUSION: The prevalence of opioid prescriptions for terminally ill cancer patients has increased from 2010 to 2019 in Japan. The opioid-specific trends were similar to the global trend but differed by palliative care specialty.
