Clinical Trial Observational Study
Characterisation of gut, lung, and upper airways microbiota in patients with non-small cell lung carcinoma: Study protocol for case-control observational trial.
Several studies have confirmed the important role of the gut microbiota in the regulation of immune functions and its correlation with different diseases, including cancer. While brain-gut and liver-gut axes have already been demonstrated, the existence of a lung-gut axis has been suggested more recently, with the idea that changes in the gut microbiota could affect the lung microbiota, and vice versa. Likewise, the close connection between gut microbiota and cancer of proximal sites (intestines, kidneys, liver, etc.) is already well established. However, little is known whether there is a similar relation when looking at world's number one cause of death from cancer-lung cancer. ⋯ The study is a case-controlled observational trial. Forty NSCLC patients will be divided into 2 groups depending on their anamnesis: Pchir, patients eligible for surgery, or Pct-chir, patients eligible for neoadjuvant chemotherapy plus surgery. Composition of the UAs (saliva), gut (faeces), and lung microbiota (from broncho-alveolar lavage fluid (BALF) and 3 lung pieces: "healthy" tissue distal to tumour, peritumoural tissue and tumour itself) will be analysed in both groups. Immune properties will be evaluated on the local (evaluation of the tumour immune cell infiltrate, tumour classification and properties, immune cell phenotyping in BALF; human neutrophil protein (HNP) 1-3, β-defensin 2, and calprotectin in faeces) and systemic level (blood cytokine and immune cell profile). Short-chain fatty acids (SCFAs) (major products of bacterial fermentation with an effect on immune system) will be dosed in faecal samples. Other factors such as nutrition and smoking status will be recorded for each patient. We hypothesise that smoking status and tumour type/grade will be major factors influencing both microbiota and immune/inflammatory profile of all sampling sites. Furthermore, due to non-selectivity, the same effect is expected from chemotherapy.

Case Reports
Secondary lymphedema after high ligation of the great saphenous vein surgery: A case report.
A 56-year-old male patient with secondary lymphedema in a single lower extremity presented to our hospital. He received high ligation of great saphenous vein 3 years ago. ⋯ Compression treatment was given in affected limb to promote the lymphatic return. The patient was followed up for 3 months now, the edema in right leg showed attenuation compared with before.

Tropisetron is an adjuvant for dezocine used in intravenous patient-controlled analgesia (PCA) and has been reported to provide superior pain control. It is efficacious in reducing the institutional incidence of postoperative nausea and vomiting (PONV), which decreases resource utilization and cost. However, no scientific evidence has been reported in the literature demonstrating analytical confirmation of the compatibility and stability of the combination of dezocine and tropisetron. ⋯ After a 14-day period of storage at 4°C or 25°C, the initial concentrations of dezocine and tropisetron were maintained at at least 98%. All of the mixtures remained clear and colorless throughout the observation period, and no color change or precipitation was observed. These results indicated that admixtures of 40 mg/100 mL dezocine and 5 mg/100 mL tropisetron in 0.9% sodium chloride injection were stable for at least 14 days when stored in polyolefin bags or glass bottles at 4°C or 25°C and protected from light.

Case Reports
Sudden cardiac death due to the Wolff-Parkinson-White syndrome: A case report with genetic analysis.
The Wolff-Parkinson-White syndrome (WPW) is a benign heart disease with accessory pathways, which can result in cardiac arrhythmias. The purpose of this case report is to introduce a rare case of sudden cardiac death (SCD) with a mild myocardial bridge and a history of WPW. ⋯ This case highlights SCD can occur in WPW patients with mild or unrecognized structural abnormality. Postmortem genetic examination can assist the diagnosis of sudden cardiac death, especially when no lethal structural abnormality is found in the decedent.

Case Reports
Myocardial calcification found in Epstein-Barr viral myocarditis and rhabdomyolysis: A case report.
The Epstein-Barr (EB) virus has rarely been reported as a cause of fulminant myocarditis. To our knowledge, the present case is the first report on myocardial calcification in EB viral myocarditis and rhabdomyolysis. ⋯ This case indicates that this rare form of myocardial calcification may be associated with EB viral infection and rhabdomyolysis.
