Observational Study
The clinical features and related factors of PICC-related upper extremity asymptomatic venous thrombosis in cancer patients: A prospective study.
Peripherally inserted central venous catheter (PICC) is the main venous access for cancer patients when they receive chemotherapy and nutritional support, but PICC-related venous thrombosis has become one of the most common and serious complications. It is very important to further explore the relationship among these features, so that prevent and treat the PICC-related thrombosis. To investigate the clinical features and the related factors of PICC-related upper extremity asymptomatic venous thrombosis in cancer patients, and to provide theoretical basis for the prevention of venous thrombosis. ⋯ PICC catheterization can affect blood flow and asymptomatic thrombosis can occur at an early stage. Patient's upper limb activities should be guided to promoting blood circulation, thus effectively preventing thrombosis. Asymptomatic thrombosis can also be detected by color Doppler ultrasound system, within a recommended time of 1 week after catheterization.

To investigate the characteristics of spiral computed tomography (CT), positron emission tomography-computed tomography (PET/CT) and clinical manifestations of talaromycosis to improve the diagnostic level and deepen its recognition in radiology. Radiological, clinical, and pathological manifestations of 15 patients of non-HIV talaromycosis confirmed by bronchofiberscope lung biopsy and/or abscess puncture fluid culture and/or blood culture and/or sputum culture were analyzed retrospectively. All patients underwent chest CT, among them, six had a brain MRI, and six had a PET/CT scan before treatment. ⋯ On PET/CT, five patients showed elevated standard uptake value (SUV). The radiological manifestations of non-HIV talaromycosis show multiple consolidations, ground-glass opacities, multiple nodules or masses in bilateral lungs, deep-seated enlarged lymph nodes and bone destruction in multiple systems. The final diagnosis should be based on the culture of talaromycosis.

Observational Study
Practical strategy for optimizing the timing of anti-tumor necrosis factor-α therapy in Crohn disease: A nationwide population-based study.
There is little consensus on the optimal timing of anti-tumor necrosis factor (anti-TNF) therapy to decrease the rates of hospitalization and surgery in Crohn disease (CD). We aimed to assess the real-world outcomes of anti-TNF therapy and estimate the optimal timing of anti-TNF therapy in Korean patients with CD. Claims data were extracted from the Korean Health Insurance Review and Assessment Service database. ⋯ The 5-year rate of hospitalization was significantly lower in group A than in groups C and D (P = .004 and .020, respectively), but similar between groups A and B. The 5-year rate of surgery was lower in group A than in group C (P = .024), but similar among groups A, B, and D. In Asian patients with CD, anti-TNF therapy reduces the risk of EH and surgery and should be considered before three relapses, regardless of disease duration.

Non-small cell lung cancer (NSCLC) is the major cause of cancer mortality worldwide. Though multidisciplinary therapies have been widely used for NSCLC, its overall prognosis remains very poor, presumably owing to lack of effective prognostic biomarkers. SMAD, a well-known transcription factor, plays an essential role in carcinogenesis. ⋯ In the present study, we report the distinct expression and prognostic value of individual SMAD in patients with NSCLC by analyzing several online databases including ONCOMINE, Gene Expression Profiling Interactive Analysis, Human Protein Atlas database, Kaplan-Meier plotter, cBioPortal, and Database for Annotation, Visualization and Integrated Discovery. The mRNA levels of SMAD6/7/9 in NSCLC were significantly down-regulated in NSCLC, and aberrant SMAD2/3/4/5/6/7/9 mRNA levels were all correlated with the prognosis of NSCLC. Collectively, SMAD2/3/4/5/6/7/9 may server as prognostic biomarkers and potential targets for NSCLC, and thus facilitate the customized treatment strategies for NSCLC patients.

Case Reports
Primary hepatic ectopic pregnancy in a patient with polycystic ovary syndrome: A case report.
Hepatic ectopic pregnancy is an extremely rare ectopic pregnancy. This study aimed to report a case of primary hepatic pregnancy in a patient with polycystic syndrome. ⋯ If the level of beta-human chorionic gonadotropin (β-HCG) is higher than normal in women of childbearing age and no gestational sac is found in the uterine cavity, the location of pregnancy and gestational sac should be positively confirmed. Also, the possibility of ectopic pregnancy in the abdominal cavity should be considered, and the relevant imaging and biochemical examinations should be improved to avoid delay in diagnosis and treatment.
