RESUMO
High-quality evidence indicated that both neoadjuvant carboplatin/paclitaxel (CROSS) and cisplatin/5-fluorouracil (PF) regimens in combination with radiotherapy improve survival outcomes compared to surgery alone in patients with esophageal cancer. It is not yet known whether they may differ in terms of treatment burden and healthcare costs. A total of 232 Taiwanese patients with esophageal squamous cell carcinoma who had undergone neoadjuvant chemoradiotherapy (nCRT) with either the CROSS (n = 153) or the PF (n = 79) regimens were included. Hospital encounters and adverse events were assessed for determining treatment burden. Cost-effectiveness analysis was undertaken using the total costs incurred over 3 years in relation to overall survival (OS) and progression-free survival (PFS). Compared with PF, the CROSS regimen was associated with a lower treatment burden: shorter inpatient days on average (4.65 ± 10.05 vs. 15.14 ± 17.63 days; P < 0.001) and fewer admission requirements (70% of the patients were never admitted vs. 20% in the PF group; P < 0.001). Patients in the CROSS group experienced significantly less nausea, vomiting, and diarrhea. While the benefits observed in the CROSS group were associated with additional nCRT-related expenditures (1388 United States dollars [USD] of added cost per patient), this regimen remained cost-effective. At a willingness-to-pay threshold of 50,000 USD per life-year, the probability of the CROSS regimen to be more cost-effective than PF was 94.1% for PFS but decreased to 68.9% for OS. The use of the CROSS regimen for nCRT in patients with ESCC was associated with a lower treatment burden and was more cost-effective than PF.

Sleep scoring involves the inspection of multimodal recordings of sleep data to detect potential sleep disorders. Given that symptoms of sleep disorders may be correlated with specific sleep stages, the diagnosis is typically supported by the simultaneous identification of a sleep stage and a sleep disorder. This paper investigates the automatic recognition of sleep stages and disorders from multimodal sensory data (EEG, ECG, and EMG). We propose a new distributed multimodal and multilabel decision-making system (MML-DMS). It comprises several interconnected classifier modules, including deep convolutional neural networks (CNNs) and shallow perceptron neural networks (NNs). Each module works with a different data modality and data label. The flow of information between the MML-DMS modules provides the final identification of the sleep stage and sleep disorder. We show that the fused multilabel and multimodal method improves the diagnostic performance compared to single-label and single-modality approaches. We tested the proposed MML-DMS on the PhysioNet CAP Sleep Database, with VGG16 CNN structures, achieving an average classification accuracy of 94.34% and F1 score of 0.92 for sleep stage detection (six stages) and an average classification accuracy of 99.09% and F1 score of 0.99 for sleep disorder detection (eight disorders). A comparison with related studies indicates that the proposed approach significantly improves upon the existing state-of-the-art approaches.

BACKGROUND: This retrospective study examined outcomes in esophageal squamous cell carcinoma (ESCC) patients who did not undergo surgical resection after neoadjuvant chemoradiotherapy (nCRT). METHODS: Patients receiving nCRT between 2012 and 2020 were divided into two groups: group 1 (scheduled surgery) and group 2 (no surgery). Group 2 was further categorized into subgroups based on reasons for not proceeding to surgery: group 2a (disease progression), group 2b (poor general conditions), and group 2c (patient refusal). Overall survival (OS) was the primary outcome. RESULTS: Group 1 comprised 145 patients, while subgroups 2a, 2b, and 2c comprised 24, 16, and 31 patients, respectively. The 3-year OS rate was significantly lower in group 2 compared with group 1 (34% versus 56%, p < 0.001). A subgroup analysis showed varying 3-year OS rates: 13% for group 2a, 25% for group 2b, and 58% for group 2c (p < 0.001). Propensity score matching for group 2c and group 1 revealed no significant difference in 3-year OS rates (p = 0.91). CONCLUSION: One-third of ESCC patients receiving nCRT did not undergo surgical resection. Overall survival in this group was generally poorer, except for those who refused surgery (group 2c).
RESUMO
Traumatic brain injury (TBI) is the most common cause of death and acquired disability among children and young adults in the developed countries. In clinical studies, the incidence of depression is high after TBI, and the mechanisms behind TBI-induced depression remain unclear. In the present study, we subjected rats to a moderate fluid percussion into the closed cranial cavity to induce TBI. After 3 days of recovery, injured rats were given a forced swim test (FST) and novelty-suppressed feeding tests. We found that TBI rats exhibited increased duration of immobility and longer latency to begin chewing food in a new environment compared with sham-operated rats. Western blot analysis showed that TBI led to a decrease in the phosphorylated levels of extracellular signal regulated kinases (ERK1/2) and p38 mitogen-activated protein kinase (p38 MAPK). Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), significantly reduced the duration of immobility when administered once per day for 14 days. Consistent with behavioral tests, fluoxetine treatment reversed TBI-induced decrease in p-ERK1/2 and p-p38 MAPK levels. Pre-treatment with a selective tryptophan hydroxylase inhibitor para-chlorophenylalanine (PCPA) blocked the antidepressant effect of fluoxetine. PCPA also prevented the effect of fluoxetine on ERK1/2 phosphorylation without affecting p38 MAPK phosphorylation. Pre-treatment with ERK inhibitor SL327 but not p38 MAPK inhibitor SB203580 prevented the antidepressant effect of fluoxetine. These results suggest that ERK1/2 plays a critical role in TBI-induced depression.
