[EX Q]: Endoscopic snare papillectomy (ESP) is a viable alternative to surgical treatment of ampullary adenomas and T1N0 stage ampullary carcinomas. The main drawback of this technique is the high risk of acute pancreatitis post procedure.The aim of this study was to assess the efficacy, safety, and long-term results of this procedure, and to determine whether routine pancreatic intubation facilitated by intraductal methylene blue (MB) injection reduces the risk for pancreatitis.', 'Between 2004 and 2011, 56 consecutive patients underwent ESP. Before resection, the pancreatic duct was cannulated, and MB was injected intraductally to facilitate stent placement after ampullectomy.', 'ESP was performed en bloc in 45 patients with histological findings of low-grade dysplasia (39%), high-grade dysplasia (25%), carcinoma (32.5%), and others (3.5%). The morbidity rate was 19.5%: acute pancreatitis (n=6), bleeding (n=4), perforation (n=1), and sepsis (n=1). Pancreatic intubation was performed in 89% of the patients. Postprocedure pancreatitis occurred significantly less in the patients with a pancreatic stent than in those without: 3/49 versus 3/6, P=0.013. ESP was considered as curative in 39 patients (75%). Of the 12 recurrences (25%), 10 were managed endoscopically, but with higher morbidity (acute pancreatitis=40%).

[EX Q]: Joint instability is believed to promote early osteoarthritic changes in the knee. Inflammatory reactions are associated with cartilage degradation in osteoarthritis (OA) but their possible synergistic or additive effects remain largely unexplored. The goal of the present study was to investigate the invivo effects of Botulinum Toxin A (BTX-A) induced joint instability on intraarticular alterations in an otherwise intact rabbit knee joint model.', 'Ten 1-year-old female New Zealand White rabbits (average 5.7kg, range 4.8-6.6kg) were randomly assigned to receive three monthly unilateral intramuscular injections of BTX-A (experimental group), or no treatment (control group). After 90days, all knees were analyzed for specific mRNA levels using RT-qPCR. The synovium and cartilage tissue was assessed for histological alterations using the OARSI scoring system.', 'Cartilage and synovial histology showed significant higher OARSI scores in the BTX-A group animals compared to the untreated controls and contralateral limbs. There were no differences between the untreated control and the contralateral experimental limbs. Gene expression showed significant elevations for collagen I, collagen III, nitric oxide, TGF-, IL-1 and IL-6 compared to the healthy controls.

[EX Q]: Characterizing young women's willingness to enter motherhood is critical to understanding the high rates of unintended pregnancy among women under 20 years. Our objectives were to discuss a measure called Positive Orientation towards Early Motherhood (POEM), and investigate its association with self-reported unintended pregnancy experience.", 'We used data from 332 African-American women 13-19 years old recruited at public family planning and prenatal clinics in New Orleans. Using a series of ANOVAs and multinomial logistic regression, we assessed differences in POEM between four different outcome groups: women who were never pregnant and those who had only intended pregnancies, only unintended pregnancies and both unintended and intended pregnancies.', 'The data suggested that young women perceive pregnancy as an opportunity to assert responsibility, become closer with their families and achieve greater intimacy with their boyfriends. Multiple regression analysis indicated that this positive orientation toward early motherhood independently raised the likelihood that young women experienced unintended pregnancies. In particular, the perception that a pregnancy makes a young woman feel more responsible was associated with an increased likelihood that a young woman had only unintended pregnancies compared to no pregnancies at all. Interestingly, this perception did not differentiate young women who had only intended pregnancies from those who were never pregnant.
