Hypothetical hypoxia-driven rapid disease progression in hepatocellular carcinoma post transarterial chemoembolization: A case report.

BACKGROUND: Transarterial chemoembolization (TACE) is widely performed for intermediate-stage or unresectable hepatocellular carcinoma (HCC), but approximately half of patients do not respond to TACE treatment. We describe a case of rapidly progressing of HCC after TACE and provide a possible hypothesis for this condition. The finding may contribute to identifying patients who obtain less benefit from TACE, thus avoiding the unnecessary waste of medical resources and treatment during the golden hour window. CASE SUMMARY: A 61-year-old woman had been diagnosed with chronic hepatitis B infection and HCC at Barcelona Clinic Liver Cancer stage B, which had been treated by segmental hepatectomy 14 mo ago. The tumor recurred in the two months after surgery. She received an initial TACE and then underwent systemic therapy with lenvatinib 8 mg daily due to an increased level of alpha-fetoprotein (AFP) after the first TACE. However, the tumor continued to progress with an increased level of AFP, and she underwent a second TACE, after which the tumor volume did not obviously decrease on the contrast-enhanced computed tomography image. One month later, she had a third TACE to control the residual HCC tumors. Two weeks after that, the HCC had increased dramatically with tea-colored urine and yellowish skin turgor. Eventually, the patient refused further treatment and went into hospice care. CONCLUSION: Intense hypoxia induced by TACE can trigger rapid disease progression in infiltrative HCC patients with a large tumor burden.

The long-term persistence of tumor necrosis factor inhibitors in patients with moderate to severe immune-mediated rheumatic diseases: A nation-wide, population-based real-world study.

OBJECTIVES: We aimed to compare the long-term persistence between different tumor necrosis factor-alpha inhibitors (TNFis) with immune-mediated rheumatic diseases (IMRD). This study can potentially provide insights into the real-world evidence regarding safety and effectiveness of TNFi treatment in a Chinese population. METHODS: We enrolled newly diagnosed IMRD patients in this active comparator, retrospective cohort study by using National Taiwan insurance claim datasets. The drug survivals of first-line TNFi agents, including etanercept, golimumab, and adalimumab were compared. Propensity score matching was conducted to control the confounding effect from the observed covariates. The cumulative proportion of discontinuation was calculated over 5 years. The multiple-variable regression and propensity score analysis was used for confounding adjustment. RESULTS: After propensity score matching, there were 2267 patients identified in each etanercept, golimumab, and adalimumab group. We observed the 5-year cumulative proportion of discontinuation was 52.80%, 45.85%, and 56.86% in etanercept, golimumab, and adalimumab, respectively. Compared with golimumab, increase of 31% (95% CI: 20-43) and 38% (95% CI: 26-50) risk of discontinuation were observed in etanercept and adalimumab. The factors including female gender, increasing age, long hospital stays, without co-medication with nonsteroidal anti-inflammatory drugs or methotrexate were associated were discontinuation of first-line TNFi treatment. CONCLUSION: Golimumab had better drug survival than etanercept or adalimumab over 5 years of observation in Asian IMRD patients. Gender, age, longer hospital stays, concomitant use of disease-modifying antirheumatic drugs were associated with survival with TNFis.

Netrin1 and reelin signaling are required for the migration of anterolateral system neurons in the embryonic spinal cord.

ABSTRACT: Projection neurons of the spinal cord dorsal horn which transmit pain, itch, and temperature information to the brain comprise the anterolateral system (AS). A recent molecular and genetic study showed that many developing AS neurons express the transcription factor Phox2a and provided insights into the mechanisms of their ontogeny and wiring of nociceptive neuronal circuits. Here, we show that the loss of the axonal guidance and neuronal migration signal netrin1 results in impaired migration of mouse Phox2a+ AS neurons into the spinal lamina I. Furthermore, we show that in the absence of Dab1, an intracellular transducer of the neuronal migration signal reelin, the migration of spinal lamina V and lateral spinal nucleus Phox2a+ AS neurons is impaired, in line with deficits in nociception seen in mice with a loss of reelin signaling. Together, these results provide evidence that netrin1 and reelin control the development of spinal nociceptive projection neurons, suggesting a mechanistic explanation for studies that link sequence variations in human genes encoding these neurodevelopmental signals and abnormal pain sensation.

Scoping review to evaluate the effects of peer support on the mental health of young adults.

OBJECTIVES: Young adults report disproportionality greater mental health problems compared with the rest of the population with numerous barriers preventing them from seeking help. Peer support, defined as a form of social-emotional support offered by an individual with a shared lived experience, has been reported as being effective in improving a variety of mental health outcomes in differing populations. The objective of this scoping review is to provide an overview of the literature investigating the impact of peer support on the mental health of young adults. DESIGN: A scoping review methodology was used to identify relevant peer-reviewed articles in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines across six databases and Google/Google Scholar. Overall, 17 eligible studies met the inclusion criteria and were included in the review. RESULTS: Overall, studies suggest that peer support is associated with improvements in mental health including greater happiness, self-esteem and effective coping, and reductions in depression, loneliness and anxiety. This effect appears to be present among university students, non-student young adults and ethnic/sexual minorities. Both individual and group peer support appear to be beneficial for mental health with positive effects also being present for those providing the support. CONCLUSIONS: Peer support appears to be a promising avenue towards improving the mental health of young adults, with lower barriers to accessing these services when compared with traditional mental health services. The importance of training peer supporters and the differential impact of peer support based on the method of delivery should be investigated in future research.
