Groups 3 and 1B had a significantly higher prevalence of sella turcica bridging than groups 4 and 4B, respectively. Maxillary second premolar agenesis and severe tooth agenesis were associated with a reduced ID irrespective of age and increased occurrence of sella turcica bridging. The early emergence in life of a short ID might be a predictor of possible second premolar agenesis in later life.In flexible endoscopy, the endoscope needs to be sufficiently flexible to go through the tortuous paths inside the human body and meanwhile be stiff enough to withstand external payloads without unwanted tip bending during operation. Thus, an endoscope whose stiffness can be adjusted on command is needed. This paper presents a novel variable-stiffness manipulator. The manipulator (Ø15 mm) has embedded thermoplastic tubes whose stiffness is tunable through temperature. Temperature is adjusted through joule heat generated by the electrical current supplied to the stainless steel coils and an active air-cooling mechanism. Tests and modeling were conducted to characterize the performance of the design. The manipulator has a high stiffness-changing ratio (22) between rigid and flexible states while that of its commercial Olympus counterpart is only 1.59. The active cooling time is 11.9 s while that of passive ambient cooling is 100.3 s. The thermal insulation layer (Aerogel) keeps the temperature of the outer surface within the safe range (below 41 °C). The models can describe the heating and cooling processes with root mean square errors ranging from 0.6 to 1.3 °C. Olaparib The results confirm the feasibility of a variable-stiffness endoscopic manipulator with high stiffness-changing ratio, fast mode-switching, and safe thermal insulation.Treatment of heart failure with preserved ejection fraction (HFpEF) remains a major unmet medical need. An implantable valveless pulsatile pump with a single cannula-the CoPulse pump-may provide beneficial hemodynamic support for select HFpEF patients when connected to the failing ventricle. We aimed to demonstrate hemodynamic efficacy and hemocompatible design feasibility for this novel assist device. The hemodynamic effect of the pump was investigated with an in vitro circulatory mock loop and an ex vivo isolated porcine heart model. The hydraulic design was optimized using computational fluid dynamics (CFD), and validated by 4D-flow magnetic resonance imaging (MRI). The pump reduced left atrial pressure (> 27%) and increased cardiac output (> 14%) in vitro. Ex vivo experiments revealed elevated total stroke volume at increased end-systolic volume during pump support. Asymmetric cannula positioning indicated superior washout, decreased stagnation (8.06 mm2 vs. 31.42 mm2), and marginal blood trauma potential with moderate shear stresses ( 0.76). The CoPulse pump proved hemodynamically effective. Hemocompatibility metrics were comparable to those of a previously reported, typical pulsatile pump with two cannulae. The encouraging in vitro, ex vivo, and hemocompatibility results substantiate further development of the CoPulse pump.PURPOSE Peripheral neuropathy (PN) is an intractable side effect of oxaliplatin, with no effective prophylaxis so far. Ninjin'yoeito (NYT), a Kampo medicine, is protective against oxaliplatin-induced neuronal cell injury in vitro and ameliorates oxaliplatin-induced PN in vivo. Thus, this randomized controlled trial was aimed at clarifying NYT's prophylactic effect for oxaliplatin-induced cumulative PN. METHODS 52 patients with colorectal cancers of pathological stage 3 received postoperative adjuvant chemotherapy with the CapeOX regimen eight cycles of capecitabine (2400 mg/m2) plus oxaliplatin (130 mg/m2) at 3-week intervals. They were randomly assigned to NYT administration and non-administration groups. NYT (9.0 g/day) was administered from day 1 of cycle 1 in the NYT group. The NYT was administered orally daily throughout each cycle. The primary endpoint was the grade of cumulative PN at the end of eight cycles. The secondary endpoints included relative dose intensity (RDI) of oxaliplatin, recurrence-free survival (RFS), and overall survival (OS). RESULTS 40 patients (n = 20 in both groups) completed 8 chemotherapy cycles. The incidence of grade 2 or greater cumulative PN at the 8th chemotherapy cycle was significantly lower in the NYT group (2/20, 10.0%) than in the control group (11/20, 55.0%, P  less then  0.01). RDI of oxaliplatin was significantly higher in the NYT group than in the control group (P = 0.02). RFS and OS were better in the NYT group than in the control group, but the difference was not significant. CONCLUSIONS NYT may reduce the incidence of oxaliplatin-induced cumulative PN and facilitate maintenance of the CapeOX dosing regimen.BACKGROUND The aim of this study is to establish new risk tables for the current clinical setting, enabling short- and long-term risk stratification for recurrence, progression, and cancer-specific death after transurethral resection in non-muscle invasive bladder cancer (NMIBC). Currently available risk tables lack input from the 2004 World Health Organization grading system and risk prediction for cancer-specific death. METHODS This was a multi-institutional database study of 1490 patients diagnosed with NMIBC (the development cohort). A multivariate Fine and Gray subdistribution hazard model was used to assess the prognostic impact of various factors. Patients were classified into low-, intermediate-, and high-risk groups according to a sum of the weight of selected factors, and predicted cumulative rates were calculated. Internal validation was conducted using 200 bootstrap resamples to assess the optimism for the c-index and estimate a bias-corrected c-index. External validation of the developed risk table was performed on an independent dataset of 91 patients. RESULTS The Japanese NIshinihon uro-onCology Extensive collaboration group (J-NICE) risk stratification table was derived from six, five, and two factors for recurrence, progression, and cancer-specific death, respectively. The internal validation bias-corrected c-index values were 0.619, 0.621, and 0.705, respectively. The application of the J-NICE table to an external dataset resulted in c-indices for recurrence, progression, and cancer-specific death of 0.527, 0.691, and 0.603, respectively. CONCLUSIONS We propose a novel risk stratification model that predicts outcomes of treated NMIBC and may overcome the shortcomings of existing risk models. Further external validation is required to strengthen its clinical impact.
