The aim of this study was to investigate whether rapid depletions of fat mass and skeletal muscle mass predict mortality in hepatocellular carcinoma (HCC) patients treated with sorafenib. This retrospective study evaluated 61 HCC patients. The cross-sectional areas of visceral and subcutaneous fat mass and skeletal muscle mass were measured by computed tomography, from which the visceral fat mass index (VFMI), subcutaneous fat mass index (SFMI), and skeletal muscle index (L3SMI) were obtained. The relative changes in these indices per 120 days (ΔVFMI, ΔSFMI, and ΔL3SMI) before and after sorafenib treatment were calculated in each patient. Patients within the 20th percentile cutoffs for these indices were classified into the rapid depletion (RD) group. Kaplan–Meier analysis revealed that with respect to ΔL3SMI (p = 0.0101) and ΔSFMI (p = 0.0027), the RD group had a significantly poorer survival. Multivariate analysis using the Cox proportional-hazards model also demonstrated that ΔL3SMI (≤−5.73 vs. >−5.73; hazard ratio [HR]: 4.010, 95% confidence interval [CI]: 1.799–8.938, p = < 0.001) and ΔSFMI (≤−5.33 vs. >−5.33; HR: 4.109, 95% CI: 1.967–8.584, p = < 0.001) were independent predictors. Rapid depletions of subcutaneous fat mass and skeletal muscle mass after the introduction of sorafenib indicate a poor prognosis.

Objective:To evaluate open heart surgery with deep surface-induced hypothermia (sHT) and low-flow cardiopulmonary bypass (CPB) in small and toybreed dogs. Study Design: Case series. Animals: Small breed dogs (n = 8) weighing o 5.5 kg with naturally occurring cardiac disease. Methods: Deep sHT under isoflurane anesthesia and low-flow rate CPB with a small-volume prime circuit were used. Ventricular septal defect was closed directly in 2 dogs and severe mitral regurgitation was corrected with mitral valvuloplasty (MVP) in 5 dogs and mitral valve replacement in 1 dog. Results: All dogs survived surgery; 1 dog died 6 days and 1 died 2 months after MVP. The other 6 dogs lived (mean follow-up, 32.8 months; range, 12-65 months). Mean body weight at surgery was 3.6 kg (range, 2-5.3 kg). Mean lowest esophageal temperature was 21.41C (range, 19.8-23.81C). Mean lowest pump flow volume was 29.2 mL/kg/min (range, 9.4-57.7 mL/kg/min) during aortic crossclamping (mean, 53.5 minutes; range, 25-79 minutes). Mean hematocrit before CPB was 38.6% (range, 33-47%) and 20.3% (range, 13-24%) during CPB with a small circuit priming volume of 225-260 mL. Conclusion: Deep sHT with low-flow rate CPB may be used for open heart surgery in small dogs weighing o 5.5 kg. Clinical Relevance: Open heart surgery for selected congenital defects and acquired defects in small and toy-breed dogs may be successfully performed using deep sHT and CPB.Surgical correction of acquired and congenital heart diseases is not commonly performed in small dogs (body weight o 5.5 kg) because cardiopulmonary bypass (CPB) is more difficult.

Understanding how the brain modulates improvisation has been the focus of numerous studies in recent years. Models have suggested regulation of activity between default mode and executive control networks play a role in improvisational execution. Several studies comparing formulaic to improvised sequences support this framework and document increases in activity in medial frontal lobe with decreased activity in the dorsolateral prefrontal cortex (DLPFC). These patterns can be influenced through training and neural responses may differ between in beginner and expert musicians. Our goal was to test the generalizability of this framework and determine similarity in neural activity in the prefrontal cortex during improvisation. Twenty guitarists performed improvised and formulaic sequences in a blues rock format while brain activity was recorded using functional near-infrared spectroscopy. Results indicate similar modulation in DLPFC as seen previously. Specific decreases of activity from left DLPFC in the end compared to beginning or middle of improvised sequences were also found. Despite the range of skills of participants, we also found significant correlation between subjective feelings of improvisational performance and modulation in left DLPFC. Processing of subjective feelings regardless of skill may contribute to neural modulation and may be a factor in understanding neural activity during improvisation.

Objective A 50-100-mg rectal dose of nonsteroidal anti-inflammatory drugs (NSAIDs; diclofenac or indomethacin) has been shown to prevent post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). However, this is higher than the recommended 25-mg dose that is commonly administered to Japanese patients. The objective of this study was to evaluate the safety and efficacy of 25-mg rectal dose of diclofenac in preventing PEP. Methods Between January 2016 and March 2017, a total of 147 patients underwent ERCP with or without the rectal administration of diclofenac (25 mg) 20 min before the procedure. A retrospective analysis was conducted to evaluate the efficacy and safety of this dose in preventing PEP. Results Thirteen patients (8.8%) developed PEP: 3 patients (4.1%) in the diclofenac group and 10 (13.7%) in the control group (p=0.0460). After ERCP, there were no cases of gastrointestinal hemorrhage, ulceration, acute renal failure, or death. A multivariate logistic regression analysis revealed that the non-administration of rectal diclofenac was a risk factor for PEP (odds ratio=3.530; 95% confidence interval=1.017-16.35; p=0.0468). Conclusions A 25-mg rectal dose of diclofenac might prevent PEP.

The aim of this study was to assess the annualized changes in body composition, including skeletal muscle, subcutaneous adipose tissue (SAT), and visceral adipose tissue (VAT) before, during, and after sorafenib treatment in patients with hepatocellular carcinoma (HCC). This retrospective study evaluated 61 HCC patients treated with sorafenib. Annualized changes (Δ; cm2/m2/year) in skeletal muscle index (SMI), SAT index (SATI), and VAT index (VATI), which were defined as the cross-sectional areas (cm2) of those areas on computed tomography normalized by the square of one’s height (m2), before (pre), during (during), and after (post) sorafenib treatment, were calculated. Patients within the 20th percentile cutoffs for these indices were classified into the rapid depletion group and the effects of these values on survival were analyzed using the Kaplan-Meier analysis and Cox proportional-hazards model. Annualized depletion rates of SMI (ΔSMIpre: −3.5, ΔSMIduring: −3.5, ΔSMIpost: −8.0) and VATI (ΔVATIpre: −3.2, ΔVATIduring: −2.8, ΔVATIpost: −15.1) accelerated after the cancellation of sorafenib, whereas that of SATI (ΔSATIpre: −4.8, ΔSATIduring; −7.6, ΔSATIpost; −8.0) had already accelerated during sorafenib treatment. Patients with rapid depletion of ΔSATIduring experienced significantly worse survival rates (p < 0.001), and it was an independent predictor of survival (p = 0.009), together with therapeutic effect (p < 0.001). Rapid depletion of SAT during sorafenib treatment can be used to predict survival in patients with HCC.
