ABSTRACT

Autoimmune pancytopenia is rarely seen with Hodgkin lymphoma, and only one pediatric case of pancytopenia after autologous hematopoietic stem cell transplantation (HSCT) has been reported. We herein report a case of autoimmune pancytopenia that developed after autologous HSCT for nodular lymphocyte predominant Hodgkin lymphoma (NLPHL). A 56-year-old Japanese woman underwent autologous HSCT for NLPHL. She developed autoimmune pancytopenia seven months after autologous HSCT. In this case, PSL was effective, and the blood cell counts normalized completely. However, the patient suffered from a fatal infection, probably because of immunosuppression caused by prolonged administration of PSL, as well as a history of several chemotherapies and autologous HSCT. To our knowledge, this is the first adult case of autoimmune pancytopenia after autologous HSCT for Hodgkin lymphoma. To further validate the optimal treatment strategy for autoimmune cytopenia after autologous HSCT, more cases are necessary.

ABSTRACT

Triplet regimens, such as lenalidomide, bortezomib, and dexamethasone (RVd) or thalidomide, bortezomib, and dexamethasone (VTd), are standard induction therapies for transplant-eligible patients with newly diagnosed multiple myeloma (NDMM). The addition of daratumumab to RVd and VTd has been investigated in the GRIFFIN and CASSIOPEIA trials, respectively, resulting in improvement in the rate of minimal residual disease (MRD) negativity. In this study, we conducted a cost-effectiveness analysis with a 10-year time horizon to compare first-line and second-line use of daratumumab for transplant-eligible patients with NDMM. Because long-term follow-up data for these clinical trials are not yet available, we developed a Markov model that uses MRD status to predict progression-free survival. Daratumumab was used either in the first-line setting in combination with RVd or VTd or in the second-line setting with carfilzomib plus dexamethasone (Kd). Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios were calculated from a Japanese and US payer perspective. In the Japanese analysis, D-RVd showed higher QALYs (5.43 vs 5.18) and lower costs (¥64 479,793 vs ¥71 287 569) compared with RVd, and D-VTd showed higher QALYs (5.67 vs 5.42) and lower costs (¥43 600 310 vs ¥49 471,941) compared with VTd. Similarly, the US analysis demonstrated dominance of a strategy incorporating daratumumab in first-line treatment regimens. Given that overall costs are reduced and outcomes are improved when daratumumab is used as part of a first-line regimen, the economic analysis indicates that addition of daratumumab to first-line RVd and VTd regimens is a dominant strategy compared with reserving its use for the second-line setting.

ABSTRACT

We aimed to reproduce the anthropometrical measurements of femoral dimensions using multi-planar reconstruction (MPR) computed tomography (CT); to assess the feasibility of sex estimation using femoral measurements through this approach, and to establish the corresponding sex estimation thresholds in the modern Japanese population. We used data on 224 cadavers (116 male and 108 female) that were subjected to postmortem CT and subsequent forensic autopsy at our department between October 2009 and July 2016. Four femoral measurements were obtained. Receiver operating characteristic (ROC) curve analysis was performed to test the overall ability of the variables in sex estimation, while the accuracy of the sex estimation was measured by the area under the ROC curve (AUC). The femoral bicondylar breadth showed the largest AUC values (left; 0.973, right; 0.974), followed by the maximum head diameter (left; 0.951, right; 0.955), and maximum femoral length (left; 0.885, right; 0.887). To the best of our knowledge, this is the first report to assess sex estimation based on femoral measurements, using MPR CT images.

ABSTRACT

We aimed to reproduce the anthropometrical measurement of femoral dimensions using multi-planar reconstruction computed tomography (CT), assess the correlation between stature and femoral measurements obtained by this approach, and establish a regression equation for estimating stature in the modern Japanese population. We used data regarding 224 cadavers (116 males, 108 females) that were subjected to postmortem CT and subsequent forensic autopsy at our department between October 2009 and July 2016. To simulate the placement of the femur on the osteometric board using reconstructed CT images, we defined a virtual horizontal plane (VHP) based on the three most dorsal points of the femur (lateral condyle, medial condyle, and greater trochanter). Five femoral measurements including the maximum femoral length (MFL) were obtained. The correlations between stature and each femoral measurement were expressed in terms of the coefficient of determination (R2). On regression analysis, MFL provided the lowest value for the standard error of the estimation (SEE); the SEE values in all subjects, males, and females, respectively, were 3.783 cm (R2 = 0.832), 3.850 cm (R2 = 0.653), and 3.340 cm (R2 = 0.760) for MFL on the left side and 3.747 cm (R2 = 0.835), 3.847 cm (R2 = 0.650), and 3.290 cm (R2 = 0.687) for MFL on the right side. Multiple regression equations using MFL and femoral epicondylar breadth were slightly superior to simple regression equations in males and in all subjects (SEE = 3.44-3.55 cm), whereas no effective equation could be obtained in females. To our knowledge, this is the first multiple regression equation for stature estimation using only femoral measurements.

ABSTRACT

Concise synthesis of oligo(thienylene-vinylene) with a head-to-tail type structure is achieved by regioselective deprotonative coupling of 3-hexylthiophene. The palladium catalyzed reaction of 3-hexylthiophene with (E)-2-(2-bromoethenyl)-3-hexylthiophene takes place to afford head-to-tail type trans-1,2-dithienylethene. Further extension of a vinylthiophene unit is similarly performed in an iterative manner.

ABSTRACT

OBJECTIVES: Symptoms of three-dimensional (3D) sickness, such as intoxication and eye fatigue, have been observed in subjects viewing 3D films and vary according to the image quality and visual environment. In addition, the influence of stereoscopic vision on the incidence of 3D sickness has not been explored sufficiently. Therefore, it is important to examine the safety of viewing virtual 3D content. METHODS: The present study examines the effects of peripheral vision on reported motion sickness during exposure to 2D/3D video clips for 1 min and for 1 min afterwards in human subjects. Stabilograms were recorded during exposure to video clips with or without visual pursuit of a 3D object and compared, and subjects were administered the simulator sickness questionnaire after stabilometry. RESULTS: There were no significant main effects of solidity of the visual stimulous (2D/3D) and the vision method (visual pursuit/peripheral viewing) in accordance with the two-way analysis of variance of the sway values, although the sway values during the 2D/3D video clips were higher than in control subjects. A consistent trend in the main effect of stability was observed. Further, the sway values changed remarkably after the 3D video clip was viewed peripherally and produced a persistent instability in equilibrium function. The questionnaire findings also significantly changed after the subjects viewed the video clips peripherally. CONCLUSIONS: Subjective exacerbation and deterioration of equilibrium function were observed after peripheral viewing of 3D video clips. This persistent influence may result when subjects view a poorly depicted background element peripherally, which generates depth perception that contradicts daily experience.
