RESUMO

Although studies have suggested an association between lung infections and increased risk of neuronal disorders (e.g., dementia, cognitive impairment, and depressive and anxious behaviors), its mechanisms remain unclear. Thus, an experimental mice model of pulmonary sepsis was developed to investigate the relationship between lung and brain inflammation. Male Swiss mice were randomly assigned to either pneumosepsis or control groups. Pneumosepsis was induced by intratracheal instillation of Klebsiella pneumoniae, while the control group received a buffer solution. The model's validation included assessing systemic markers, as well as tissue vascular permeability. Depression- and anxiety-like behaviors and cognitive function were assessed for 30 days in sepsis survivor mice, inflammatory profiles, including cytokine levels (lungs, hippocampus, and prefrontal cortex) and microglial activation (hippocampus), were examined. Pulmonary sepsis damaged distal organs, caused peripheral inflammation, and increased vascular permeability in the lung and brain, impairing the blood-brain barrier and resulting in bacterial dissemination. After sepsis induction, we observed an increase in myeloperoxidase activity in the lungs (up to seven days) and prefrontal cortex (up to 24 h), proinflammatory cytokines in the hippocampus and prefrontal cortex, and percentage of areas with cells positive for ionized calcium-binding adaptor molecule 1 (IBA-1) in the hippocampus. Also, depression- and anxiety-like behaviors and changes in short-term memory were observed even 30 days after sepsis induction, suggesting a crosstalk between inflammatory responses of lungs and brain.

RESUMO

AIMS AND OBJECTIVES: To describe the main acupuncture techniques and parameters that have been used in the most varied symptoms of different types of cancer. BACKGROUND: Clinical evidence about the potential effectiveness of acupuncture and related therapies to control signs and symptoms associated with cancer or its treatment has been in several studies. Currently, there is already evidence of the use of acupuncture for the treatment of nausea and vomiting, fatigue, dry mouth, anxiety, depression, insomnia and pain. However, many studies lack firm rights or reproducible guidelines for treatment. DESIGN: This study performs a systematic review of clinical trials related to the topic, based on the PRISMA protocol. Thus, a search was carried out in the Scopus, Pubmed and Web of Science databases, covering studies since January 2007. METHODS: Structured and organised according to PICO standards, using keywords ("cancer" OR "malignant tumour" OR "chemotherapy" OR "radiotherapy") AND ("acupuncture" OR "electroacupuncture") AND ("pain" OR "nausea" OR "vomit" OR "fatigue" OR "xerostomia" OR "insomnia" OR "depression" OR "neuropathy"). RESULTS: After the selection and evaluation phase, 23 studies were included and analysed. CONCLUSION: Based on this analysis, it is concluded that acupuncture is safe and there is evidence of the reduction of gastrointestinal symptoms, chemotherapy-induced peripheral neuropathy, pain, dry mouth, fatigue, insomnia, and improvement of cognitive capacity. RELEVANCE TO CLINICAL PRACTICE: Acupuncture treatments could act by minimising the side effects of conventional treatments and reducing symptoms induced by tumours. NO PATIENT OR PUBLIC CONTRIBUTION: The patients had no direct involvement with the study in question.
