Abstract
e15707 Background: Advanced pancreatic ductal adenocarcinoma (PDAC) is a highly lethal disease with a five-year overall survival (OS) of less than 5%. Folfirinox and Nab-Paclitaxel plus Gemcitabine (NabPacGem) are the most active treatments in the first-line (1L). The decision to use Folfirinox or NabPacGem is a matter of debate. Methods: A retrospective cohort of advanced PDAC patients treated from January 2011 to May 2018 in four Spanish institutions was analyzed. The principal objective was to compare OS among patients receiving Folfirinox versus NabPacGem in 1L. Progression-free survival (PFS) was a secondary objective. Results: Characteristics of 251 patients included: median age 66.6 years; male 54.4%; stage IV at diagnosis 66.7%; ECOG 0/1/2 18/70/12%; treated with Folfirinox 18.3% and NabPacGem 81.7%. Patients treated with Folfirinox versus NabPacGem were younger (median age 58.3 vs. 67.9; p<0.001) and had lower ECOG (0/1/2 of 46/54/0% vs. 13/71/16%; p<0.001). Univariate analysis: median PFS 5.8 months (95%CI, 4.3 – 7.3) for Folfirinox and 4.2 months (95%CI, 3.7 – 5.2) for NabPacGem, HR=1.53 (95%CI, 1.1 – 2.1; p=0.012); median OS 12.7 months (95%CI, 8.4 – 14.3) for Folfirinox and 7.6 months (95%CI, 5.8 – 8.8) for NabPacGem, HR=1.38 (95%CI, 0.96 – 1.98; p=0.081). Multivariate Cox analysis (including type of treatment, ECOG and age) showed that ECOG was the only variable associated with PFS and OS (Table). Conclusions: In our study, advanced PDAC patients treated with Folfirinox were younger and had a better performance status than those treated with NabPacGem. We found no differences in survival between both treatments when adjusting by ECOG and age.[Table: see text]

Abstract
The efficacy and tolerability of an infusion of isradipine, a calcium antagonist of the dihydropyridine type, were tested in patients in hypertensive crisis. Ten patients with symptomatic and significant elevations in blood pressure were infused for 12 h with isradipine at 1.2, 2.4, 4.8, and 7.2 micrograms/kg/h (3 h of each infusion level). No untoward effects or adverse reactions were noted. No alterations were observed on electrocardiographic tracings, and blood pressure was significantly reduced only at doses of 7.2 micrograms/kg/h. Thus, isradipine as an infusion is useful and safe for hypertensive crisis, starting at a rate of 7.2 micrograms/kg/h. Higher doses may yet prove to be safe, well tolerated, and even more efficacious.

Abstract
In view of the possibility that cardiac hypertrophy may be reversed by isradipine, we studied the effect of two different doses of isradipine (1.0 and 7.0 mg/kg per day) on relative cardiac weight in the rat. These doses have proved equipotent in lowering the blood pressure of the two-kidney, one clip model of hypertension. Untreated hypertensive rats had significantly greater cardiac weights than the untreated controls (3.16 +/- 0.06 versus 2.31 +/- 0.05 mg/g, P less than 0.001). Hypertrophy was still present in the group treated with isradipine at 1.0 mg/kg per day (3.17 +/- 0.07 versus 2.30 +/- 0.03 mg/g; P less than 0.001) but not with 7.0 mg/kg per day (2.55 +/- 0.17 versus 2.37 +/- 0.11 mg/g; NS). Functional studies revealed that reversal of cardiac hypertrophy did not affect cardiac performance compared with the ventricles with increased mass. These results suggest that reversal of left ventricular hypertrophy with isradipine is dependent on complex mechanisms, possibly unrelated to the unloading of the heart.

Abstract
19 patients diagnosed as non-tuberculous infectious spondylodiscitis (NTIS) have been studied retrospectively over the last 10 years in three general hospitals. The etiology of 13 cases was confirmed (there were nine cases of Staphylococcus aureus, two of Brucella, one of Pseudomonas aeruginosa and another of Salmonella typhi), and the diagnosis of the remaining cases was based on clinical and radiological data as well as on the evolution with antibiotic treatment. The age of the majority of these patients ranged between 40 and 60 years (p less than 0.05), showing a clear predominance of males (p less than 0.05). The most frequently appearing symptom at the beginning of the disease was local pain which was observed in nine patients; the rest presented mixed symptoms which led to misdiagnosis at admission; an exploratory laparotomy was carried out in one patient. The interval from the symptoms' onset to diagnosis ranged between two and sixteen weeks, with an average of 6.8 weeks. The VSG had values between 22 and 148 mm during the first hour, with an average of 83.3 mm. Seven patients underwent surgery, six of them presenting paraparesis-paraplegia, while another presented cervical spondylodiscitis. One patient passed away, two persisted with paraparesis-paraplegia as an irreversible sequela and one with persistent local pain.
