Abstract
Corryocactus brevistylus (K. Schum. ex Vaupel) Britton & Rose (Cactaceae) is a shrubby or often arborescent cactus popularly known as "sancayo" and produce an edible fruit known as "Sanky" which is consumed in Arequipa-Perú. The purpose of this study was to report the gastroprotective activity and relate this activity to the antioxidant capacity and presence of phenolic compounds for the first time. A metabolomic profiling based on Ultrahigh-pressure liquid chromatography and electrospray high resolution mass spectrometry, and the antioxidant activities (DPPH, ABTS, and FRAP), ascorbic acid content, total phenolics and flavonoids contents, and the mode of gastroprotective action of the Sanky fruit including the involvement of prostaglandins, nitric oxide, and sulfhydryl compounds is reported. Thirty-eight compounds were detected in the ethanolic extract including 12 organic acids, nine hydroxycinnamic acids, three isoamericanol derivatives, six flavonoids, five fatty acids, and two sterols. The results of the biological tests showed that the ethanolic extract had antioxidant capacity and gastroprotective activity on the model of HCl/EtOH-induced gastric lesions in mice (at 10, 25, 50, and 100 mg/kg). The effect elicited by the extract at 50 mg/kg was reversed by indometacin and N-ethylmaleimide but not by NG-nitro-L-arginine methyl ester suggesting that sulfhydryl groups and prostaglandins are involved in the mode of gastroprotective action. In conclusion, our study proves that C. brevistylus pears have some gastroprotective and antioxidant capacities and consumption is recommended for the presence of several bioactive compounds.

Abstract
BACKGROUND Treatment of frail patients with advanced colorectal cancer (CRC) is controversial. This pilot phase II trial aimed to assess the efficacy and safety of regorafenib when administered in first-line to frail patients with advanced CRC. METHODS Frail patients without prior advanced colorectal cancer treatment were included in the study. Definition of frailty was defined per protocol based on dependency criteria, presence of chronic comorbid pathologies and/or geriatric features. MAIN OBJECTIVE to assess progression-free survival (PFS) rate at 6 months. Treatment consisted of 28-day cycles of orally administered regorafenib 160 mg/day (3 weeks followed by 1 week rest). RESULTS Forty-seven patients were included in the study. Median age was 81 years (range 63-89). Frailty criteria: dependency was observed in 26 patients (55%), comorbidities in 27 (57%) and geriatric features in 18 (38%). PFS rate at 6 months was 45% (95% confidence interval [CI] 30-60]. Median PFS was 5.6 months (95%CI 2.7-8.4). Median overall survival (OS) was 16 months (95%CI 7.8-24). Complete response, partial response and stable disease were observed in one, two and 21 patients respectively (objective response rate 6.4%; disease control rate 51%). Thirty-nine patients (83%) experienced grade 3-4 adverse events (AEs). The most common grade 3-4 AEs were hypertension (15 patients; 32%), asthenia (14; 30%), hypophosphatemia (6; 13%); diarrhea (4; 8%), hand-foot-skin reaction (4; 8%). There were two toxic deaths (4.2%) (grade 5 rectal bleeding and death not further specified). Dose reduction was required in 26 patients (55%) and dose-delays in 13 patients (28%). CONCLUSIONS The study did not meet the pre-specified boundary of 55% PFS rate at 6 months. Toxicity observed (83% patients experienced grade 3 and 4 AEs) preclude its current use in clinical practice on this setting. Disease control rate and overall survival results are interesting and might warrant further investigation to identify those who benefit from this approach. TRIAL REGISTRATION This trial was prospectively registered at EudraCT ( 2013-000236-94 ). Date of trial registration: April 9th, 2013.

Abstract
Mulinum crassifolium Phil. (Apiaceae) is an endemic shrub from Chile commonly used as infusion in traditional medicine to treat diabetes, bronchial and intestinal disorders and stomach ailments, including ulcers. From the EtOAc extract of this plant, the new mulinane-type diterpenoids 3 and 5 were isolated along with three known diterpenoids. The gastroprotective effect of the infusion of the plant was assayed to support the traditional use and a fast HPLC analysis using high resolution techniques was performed to identify the bioactive constituents. The EtOAc extract and the edible infusion showed gastroprotective effect at 100 mg/kg in the HCl/EtOH induced gastric ulcer model in mice, reducing lesions by 33% and 74%, respectively. Finally, a metabolomic profiling based on UHPLC-ESI-MS/HRMS of the edible infusion was performed and thirty-five compounds were tentatively identified including quercetin, caffeic acid, apigenine glucoside, p-coumaric acid, chlorogenic acids, and caffeoylquinic acids, which have been associated previously with gastroprotective and antiulcer properties. This scientific evidence can support the contribution of polyphenols in the gastroprotective activity of the edible infusion of this plant, and can validate at least in part, its ethnopharmacological use.

Abstract
Recent advances in the early diagnosis of fetal CAKUT with an increase in fetal surgical interventions have led to a growing number of neonatal survivors born with severe renal dysfunction. This, in turn, has required the development of multi-disciplinary treatment paradigms in the individualized management of these infants with advanced stage kidney disease from birth. Early multi-modal management includes neonatal surgical interventions directed toward establishing adequate urine flow, respiratory support with the assessment of pulmonary hypoplasia, and establishing metabolic control to avoid the need for dialysis intervention. The development of specialized imaging to assess for residual renal mass with non-invasive 3-dimensional techniques are rapidly evolving. The use of non-radioactive imaging offers improved safety and allows for early prognostic-based planning including anticipatory guidance for progression to end stage renal disease (ESRD). The trajectory of kidney function during the neonatal period as determined by peak and nadir serum creatinine (SCr) and cystatin C (CysC) during the first months of life provides a guide toward individualized prospective management. This is a single center experience based on a birth cohort of 42 subjects followed prospectively from birth for an average of 6.1 ± 2.8 years at the University of Miami/Holtz Children's Hospital during the past decade. There was an 8:1 male: female ratio. The birth cohort was divided into 3 subgroups according to CKD Stages at the current age: CKD 1-2 (Group 1) (eGFR ≥ 60 ml/min/1.73 m2) (N = 15), CKD stage 3-5 (Group 2) (eGFR ≤ 59 ml/min/1.73 m2) (N = 12), and ESRD-Dialysis and/or Transplantation (Group 3) (N = 15). A neonatal CysC >3.0 mg/L predicted progression to ESRD while a nadir SCr >0.6 mg/dL predicted progression to CKD 3-5 with the highest specificity and sensitivity by ROC-AUC analysis (P < 0.0001). Medical management was directed toward nutritional support with novel formula designs, early introduction of growth hormone and strict control of mineral bone disorder. One of the central aspects of the management was to avoid dialysis for as long as feasible with a primary goal toward pre-emptive transplantation.

Abstract
Background: Azorella compacta is a rare yellow-green compact resinous cushion shrub growing from the high Andes of southern Perú to northwestern Argentina, and which is a producer of biologically active and unique diterpenoids. Objective: This study investigated the secondary metabolites present in a Peruvian sample of Azorella compacta and the evaluation of gastroprotective activity of the isolated compounds in a gastric- induced ulcer model in mice. Material and Methods: Six secondary metabolites (diterpenoids 1-6) present in the dichloromethane (DCM) extract of A. compacta growing in Perú were isolated by a combination of Sephadex LH-20 permeation and silica gel chromatography and their chemical structures were elucidated by spectroscopic methods (NMR) and molecular modeling. The gastroprotective activity of the new compound 1 was evaluated on the HCl/EtOH-induced gastric lesion model in mice and compared to the activity showed by the known compounds. Results: A new mulinane diterpene along with five known diterpenoids have been isolated from a Peruvian sample of A. compacta and the gastroprotective results show that compound 1 is less active than the other known mulinane diterpenoids isolated. Conclusions: A. compacta growing in Perú showed the presence of the new mulinane 1, which was poorly active in the HCl/EtOH-induced gastric lesion model in mice. Indeed, the activity was lower than other diterpenoids (2-6) showing an oxygenated function at C-16 or/and C-20, which confirm the role of an oxygenated group (OH or carboxylic acid) for the gastroprotective activity of mulinane compounds.

Abstract
Great interindividual variability in the pharmacokinetics of mycophenolate mofetil (MMF) exists among kidney transplanted patients. The within-patient variability in stable transplanted patients is not well established. We performed 258 determinations of trough MMF levels in 86 stable transplant patients without hematological or gastrointestinal toxicity after at least year of a functioning kidney and a fixed dose of MMF. We examined the within-patient variability of levels related with clinical factors (age, gender, underlying cause of kidney failure, time since transplant, associated immunosuppression, and MMF dose) and analytical factors (serum creatinine, proteinuria, hemoglobin). Trough MMF levels were 3.6 mg/L, percentile (Pc) 25 1.6 mg/L, Pc 75 4.4 mg/L with intraindividual variability median of 65% (Pc 25 14%, Pc 75 79%). For the data analysis a variation of 14% was chosen, which corresponded to the 25th percentile. We did not observed differences between patients with variation below or above the Pc 25 in age, gender, underling cause of kidney failure, basal MMF levels, and MMF dose. Patients with greater variations showed significantly higher serum creatinine and proteinuria values than the others (1.84 +/- 0.54 vs 1.46 +/- 0.44 mg/dL and 0.45 +/- 0.42 vs 0.19 +/- 0.14 g/L; P < .05). Therefore, great within-patient variability in trough MMF levels was associated with poor kidney function and proteinuria.

Abstract
The usefulness of mycophenolate mofetil (MMF) levels in stable kidney transplant patients is not well known. We measured MMF trough levels in 137 adult kidney recipients with more than 1 year of stable graft function. The MMF dose was adjusted according to hematological or gastrointestinal toxicity, it was 500 mg in 22 (16%) patients; 750 mg in 22 (16%); 1000 mg in 69 (50.5%); 1500 mg in 15 (11%); and 2000 mg in 9 (6.5%). We analyzed the total dose, virgule dose/kg, and MMF levels in relation to efficacy parameters (creatinine, proteinuria) and hematological toxicity (erythrocytes, leukocytes, and platelets) at the time of MMF level determinations and 3 months thereafter. Statistical analyses were performed with SSPS 12.0, including sensitivity and specificity analyses by ROC. Mean MMF levels were 3.68 mg/L (Pc25, 1.6-Pc75, 4.4 mg/L) with significant differences according to dose (P < .001). Trough MMF levels did not have discriminatory capacity in the area under the ROC for anemia, renal failure, or proteinuria at the time of determination or 3 months later. The percentage of patients without proteinuria was high among patients with MMF levels between 1.6 and 4.4 mg/L. The MMF levels were low in patients who had a major increase in creatinine (1.6 vs 3.8 mg/L, P < .05). In stable renal transplant patients the levels of MMF were related to the administered dose, and they are higher than those previously described in patients with less than a year follow-up with a functioning kidney. They did not have discriminatory value at the time of determination or 3 months later. Nevertheless, low MMF levels could help recognize patients at risk of developing chronic nephropathy.

Abstract
Sulfadiazine acute nephrotoxicity is reviving specially because of its use in toxoplasmosis in HIV-positive patients. We report 4 cases, one of them in a previously healthy person. Under treatment with sulfadiazine they developed oliguria, abdominal pain, renal failure and showed multiple radiolucent renal calculi in echography. All patients recovered their previous normal renal function after adequate hydration and alcalinization. A nephrostomy tube had to be placed in one of the patients for ureteral lithiasis in a single functional kidney. None of them needed dialysis or a renal biopsy because of a typical benign course. Treatment with sulfadiazine requires exquisite control of renal function, an increase in water ingestion and possibly the alcalinization of the urine. We communicate a case in a previously healthy person, a fact not found in the recent literature. Probably many more cases are not detected. We think that a prospective study would be useful.

Abstract
Between 1991 and 1993, it was observed epidemiologically that respiratory disturbances in lambs are associated with high temperatures during the summer. The etiological agent isolated is principally Mycoplasma ovipneumoniae; moreover, Actinobacillus pleuropneumoniae biovar A has been isolated in a high number of samples. Histopathologically, an interstitial bronchopneumonia was the main lesional finding; this lesion is associated with previous mycoplasma infection.
