Abstract A brief background discussion. Nanoparticle albumin-bound paclitaxel (nab-PTX) has been developed under the concept of improved drug delivery. nab-PTX has been shown to significantly increase progression-free survival compared with solvent-based paclitaxel (PTX) in metastatic breast cancer. However, the long-term outcomes of nab-PTX induced peripheral neuropathy (nPIPN) have not yet been fully elucidated. Trial design: observational cohort study (UMIN20852) Primary objective: The long-term outcome of nPIPN Secondary objectives (1)The validity of the Neuropathic Pain Screening Questionnaire (Japan–Q, Ishikawa et al. Pain Research 2016 ) (2) To evaluate the effect of frozen gloves and elastic stockings for nPIPN nPIPN was assessed by the Japan-Q (J-Q) and Common Toxicity Criteria for Adverse Events ver 4.0 (CTC). The J-Q is an assessment tool for patient-reported pain severity, which consists of seven items, each rated on a five-point scale 0-4; grade 0 (no symptoms) to grade 4 (verysevere symptoms). Pricking pain, electric shock pain, burn like pain, tingling pain with numbness, allodynia, reduced or hyper sensitivity and hand-foot syndrome. Assessment was performed every day during chemotherapy, six months and one year after completion of nab-PTX therapy. Total of 28 points for each day and 588 points for each cycle, higher point correlates with severity. Frozen gloves during administration of nab-PTX and/or elastic stockings were optionally used. Statistical methods Kruskal Wallis test was used and p<0.05 was considered as significant. RESULTS: Between May 2013, and April 2016, 105 patients were enrolled from 7 hospitals. In 73 patients (69.5%) nab-PTX was administered as primary and in 32 patients (30.5%) as adjuvant therapy. Forty three (41.0%) patients received nab-PTX as first line and 62 (59.0%) received after anthracycline contained regimen. Trastuzumab was administered as combination therapy with nab-PTX for Her2 positive patients. Both frozen gloves and stockings were used in 21 patients (20.0%) and frozen gloves only were used in 21 patients (20.0%) according to patient preference. One hundred patients (95.2%) completed four courses, and overall relative dose intensity was 91.4%. During chemotherapy, J-Q scores go elevated from day 1 to day 5 and gradually declined throughout the rest of the cycle. Without using frozen gloves, there was a significant increase according to courses (1st: 45.0 ± 5.7, 2nd: 76.7 ± 8.6, 3rd: 94.3 ± 11.8, 4th: 95.4 ± 11.8). Using frozen gloves, there was a significant increase from 1st course to 2nd, but no further increase was observed(1st: 37.4 ± 8.1, 2nd: 61.9 ± 12.4, 3rd: 62.9 ± 10.4, 4th: 55.3 ± 10.6). After six month and one year, the scores were significantly lower compared with the last day of the fourth cycle (4.28 ± 0.50, 2.53 ± 0.25, 2.85 ± 0.39, respectively). CTC, grade 2 or more sensory disturbance was observed in 57.9% after four cycles, but improved to 9.5% and 5.4% after six month and one year respectively. CONCLUSIONS: Patient-reported nPIPN was significantly getting worse without frozen gloves during chemotherapy, however be largely reversible within 1 year of PST or adjuvant treatment. The J-Q findings support that nab-PTX treatment is tolerable.

Substantial variability exists among countries regarding the modes of death in pediatric intensive care units (PICUs). However, there is limited information on end-of-life care in Japanese PICUs. Thus, this study aimed to elucidate the characteristics of end-of-life care practice for children in a Japanese PICU. We examined life-sustaining treatment (LST) status at the time of death based on medical chart reviews from 2010 to 2014. All deaths were classified into 3 groups: limitation of LST (limitation group, death after withholding or withdrawal of LST or a do not attempt resuscitation order), no limitation of LST (no-limitation group, death following failed resuscitation attempts), or brain death (brain death group). Of the 62 patients who died, 44 (71%) had limitation of LST, 18 (29%) had no limitation of LST, and none had brain death. In the limitation group, the length of PICU stay was longer than that in the no-limitation group (13.5 vs 2.5 days; P = .01). The median time to death after the decision to limit LST was 2 days (interquartile range: 1-5.5 days), and 94% of the patients were on mechanical ventilation at the time of death in the limitation group. Although limiting LST was a common practice in end-of-life care in a Japanese PICU, a severe limitation of LST such as withdrawal from the ventilator was hardly practiced, and a considerable LST was still provided at the time of death.

Neonatal diabetes mellitus (NDM) is a monogenic insulin-dependent diabetes that develops within 6 months of age. The progression of hyperglycemia until diagnosis is unknown. Glycemic control indicators at diagnosis are useful to estimate the extent and duration of hyperglycemia. We recently established that age-adjusted glycated albumin (GA) is a useful indicator of glycemic control, regardless of age. To compare the levels of various glycemic control indicators at diagnosis between NDM and other types of insulin-dependent diabetes mellitus. We included 8 patients with NDM, 8 with fulminant type 1 diabetes (FT1D), and 24 with acute-onset autoimmune type 1 diabetes (T1AD). Plasma glucose, glycated hemoglobin (HbA1c), GA, and age-adjusted GA (calculated as previously reported) were measured and compared. There were no significant differences in the plasma glucose levels of the group of patients with NDM and those with FT1D or T1AD. HbA1c and GA levels in the NDM group were not significantly different from those in the FT1D group, and both indicators were lower than those in the T1AD group. Age-adjusted GA levels in the NDM group did not differ significantly from those in the T1AD group, but were higher than those in the FT1D group. These findings suggest that the time-course of plasma glucose elevation in NDM until diagnosis is similar to that in T1AD. In addition, the high age-adjusted GA value at diagnosis of NDM indicates that this test is useful for assessing chronic hyperglycemia in NDM.

Recently, cerebrospinal fluid (CSF) biomarkers related to Alzheimer's disease (AD) have garnered a lot of clinical attention. To explore neurophysiological traits of AD and parameters for its clinical diagnosis, we examined the association between CSF biomarkers and electroencephalography (EEG) parameters in 14 probable AD patients. Using exact low-resolution electromagnetic tomography (eLORETA), artifact-free 40-sesond EEG data were estimated with current source density (CSD) and lagged phase synchronization (LPS) as the EEG parameters. Correlations between CSF biomarkers and the EEG parameters were assessed. Patients with AD showed significant negative correlation between CSF beta-amyloid (Aβ)-42 concentration and the logarithms of CSD over the right temporal area in the theta band. Total tau concentration was negatively correlated with the LPS between the left frontal eye field and the right auditory area in the alpha-2 band in patients with AD. Our study results suggest that AD biomarkers, in particular CSF Aβ42 and total tau concentrations are associated with the EEG parameters CSD and LPS, respectively. Our results could yield more insights into the complicated pathology of AD.

Fulminant type 1 diabetes mellitus (FT1DM) develops as a result of very rapid and almost complete destruction of pancreatic β cell. The most common form of type 1 diabetes mellitus with onset during pregnancy has been shown to be FT1DM at least in Japan. We previously reported that the ratio of glycated albumin (GA) to HbA1c (GA/HbA1c ratio) is elevated in FT1DM patients at the diagnosis. In the present study, we investigated whether the GA/HbA1c ratio is also elevated in FT1DM with onset during pregnancy (P-FT1DM). The study subjects consisted of 7 patients with P-FT1DM. Ten patients with untreated type 2 diabetes mellitus (T2DM) discovered during pregnancy (P-T2DM) and 9 non-pregnant women with untreated T2DM (NP-T2DM) were used as controls. All study patients satisfied HbA1c < 8.7%, the diagnostic criteria for FT1DM. The GA/HbA1c ratio in the P-FT1DM patients at the diagnosis was significantly higher than that in the P-T2DM patients and the NP-T2DM patients. The GA/HbA1c ratio was ≥ 3.0 in all P-FT1DM patients, whereas it was < 3.0 in 8 of 10 P-T2DM patients and all NP-T2DM patients. The GA/HbA1c ratio was also elevated in P-FT1DM patients at the diagnosis compared with T2DM with or without pregnancy.
