Abstract
Objective Evidence regarding perioperative care in colorectal surgery has recently increased, leading to changes in classical clinical procedures that make the perioperative period safer and shorter. This survey aimed to evaluate the opinions of Spanish colorectal surgeons on the perioperative management of their patients. Method Emailed surveys submitted to the members of Spanish Coloproctological Associations. Results One hundred and thirty-one (31.7%) of the 413 members participated in the study and responded thus: 21% use clinical pathways and 8% use fast track (FT); 36% use epidural analgesia in colonic surgery and 57% in rectal; 40% use warm air and 23% warm fluids to maintain intraoperative normothermia; 53% prescribe >/= 3000 ml. of iv fluids on the first postoperative day and 6.2%</= 2000 ml; 43% never use nasogastric tubes. Oral intake was initiated by 23.5% on the first day, and by 50% when peristalsis began, with an earlier tendency in laparoscopic surgery; 43% believed oral intake reduces ileus, but 12% considered it dangerous. Board accreditation and experience in Coloproctology were significantly associated with a lesser use of nasogastric tubes and earlier feeding. Sixty-nine per cent considered FT reduces postoperative stay and 44% thought that it minimizes complications. Conclusion Spanish surgeons maintain a classical procedural policy, but show tendencies towards optimizing patients' care.

Abstract
INTRODUCTION Acute cellular rejection is a major cause of graft loss in heart transplantation (HT). Endomyocardial biopsy remains the gold standard for its diagnosis, but it is an invasive procedure not without risk. A proinflammatory state exists in rejection that could be assessed by determining plasma levels of inflammatory biomarkers. OBJECTIVE To analyze the utility of various inflammatory markers, which is most important and what values best classify patients to diagnose rejection. MATERIALS AND METHODS A prospective study in 123 consecutive cardiac transplant recipients was conducted from January 2002 to December 2006. Fibrinogen protein (Fgp) and function (Fgf), C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and sialic acid (SA) determinations were performed at one, two, four, six, nine, and 12 months post-HT at the same time as biopsies. Coronary arteriography and intravascular ultrasound were performed on the first and last follow-up visits. Heart-lung transplants, retransplants, pediatric transplants, patients who died in the first month, and patients who refused consent were excluded. Also excluded were determinations that coincided with renal dysfunction, active infection, hemodynamic instability, or a non-evaluable biopsy. The final analysis included 79 patients and 294 determinations. The correlation between the levels of these biomarkers and the presence of rejection in the biopsy (> or = ISHLT grade 3) was studied. RESULTS We did not find significant differences in the values of any of the markers analyzed on the six follow-up visits. Only CRP showed significant and sustained differences between the two groups (with and without rejection) from the second follow-up visit (month 2). The area under the curve showed significant differences in Fgp (0.614, p = 0.013), Fgf (0.585, p = 0.05), TNF-alpha (0.605, p = 0.02), SA (0.637, p = 0.002) and mainly CRP (0.765, p = 0.0001). CRP levels below 0.87 mg/dL ruled out rejection with a specificity of 90%. CONCLUSIONS Among the inflammatory markers analyzed, CRP was the most useful parameter for non-invasive screening of acute cellular rejection in the first year post-HT.

Abstract
INTRODUCTION The side effects of proliferation signal inhibitors (PSIs) have been characterized as a class. However, it would be convenient to assess them according to the molecule. OBJECTIVE To assess prospectively the tolerance of PSIs among heart transplant (HT) patients. PATIENTS AND METHODS We studied 56 HT patients who sequentially received PSIs to either withdraw (77%) or reduce the dosage of a calcineurin inhibitor; 42 received everolimus (EVE) and 14 sirolimus (SRL). We analyzed the demographic variables, side effects, and need to withdraw the drug during a median follow-up period of 365 days. RESULTS No differences between groups were observed upon analysis of the clinical and demographic variables when the treatment was changed owing to renal dysfunction (67%) or tumor (32%). No difference between groups was observed over the follow-up period (P = .28). Infection was the most common side effect, 28.6%: EVE, 14.3% versus SRL, 71.4% (P < .0001). Edema occurred in 26.8% of patients: EVE, 14.3% versus SRL, 64.3% (P = .001); diarrhea in 5.4% of patients: EVE, 2.4% versus SRL, 14.3% (P = .15). Treatment was withdrawn in 23.2% of the patients due to intolerance: EVE, 11.9% versus SRL, 57.1% (P < .0001). EVE showed significantly better survival without edema or infections or used for drug withdrawal upon Kaplan-Meier analysis, (P = .01; P = .0005; P = .0097). Only SRL use was shown to be an independent predictor of side effects. CONCLUSION Edema and infections are the main problems caused by PSIs. EVE may display a better tolerance profile than SRL.

Abstract
microRNAs have recently opened new pathways to explain gene expression and disease biology in many scenarios, including cardiac diseases. microRNAs are endogenous small non-coding RNAs that mediate post-transcriptional repression or messenger RNA degradation. By annealing to inexactly complementary sequences in the 3' untranslated region of the target messenger RNA, protein level is down-regulated. Several microRNAs appear to act cooperatively through multiple target sites in one gene and, conversely, most microRNAs can target several genes. miR-133 and miR-1 are specifically expressed in cardiac and skeletal muscle and control myogenesis, cardiac development, cardiac performance and cardiomyocyte hypertrophy (mainly by tuning transcription factors and other growth-related targets). They also modulate the expression of certain cardiac ion channels and related proteins with proarrhythmic effect. Besides them, other microRNAs have been shown to exert influence on the myocardial growth, the electrical balance and the angiogenesis processes that take place in the heart. Bioinformatics is a useful tool to identify potential targets of a given microRNA, although there is still substantial concern about their reliability. Experimental manipulation of microRNAs has provided a tantalizing basis to speculate that future research on microRNAs may yield important progress in the prevention of sudden cardiac death and in the treatment of cardiac heart failure. However, the final effect of the blockage of microRNAs in vivo remains unclear, since each of them can target hundreds of genes with different intensity. The era of the microRNAs in cardiovascular diseases has just started.

Abstract
INTRODUCTION Idiopathic dilated cardiomyopathy (DCM) is, together with ischemic heart disease, the major cause of end-stage heart failure leading to heart transplantation. However, an unknown percentage of patients with this diagnosis has inflammatory foci found in the histopathological study of the explanted heart. This fact suggests an undetected process of acute myocarditis as the cause of cardiac dysfunction. OBJECTIVE The objective of this study was to identify clinical and echocardiographic variables related to the presence of myocardial infiltrates, as a potential guide to determine which patients should undergo endomyocardial biopsy in DCM. MATERIALS AND METHODS We retrospectively analyzed 161 patients who underwent heart transplantation with a diagnosis of DCM between 1987 and 2007. The presence of inflammatory infiltrates was considered significant when the histopathological study of tissue blocks from the left ventricle showed 1 or more foci per cm(2) of perivascular or interstitial mononuclear or polymorphonuclear cells, whether or not in the presence of cytolysis. RESULTS Seventeen patients (11%) had these inflammatory histological findings; of them, 6 (35%) showed preponderance of eosinophils and 7 (41%) showed areas of cytolysis. The DCM group with inflammatory infiltrates showed significant differences in terms of younger age (45 +/- 15 vs 50 +/- 11 years; P < .01) and smaller ventricular diameters (P < .05). Male gender was more frequent in this group, and the patients had a poorer clinical status and greater dependence on inotropic drugs. CONCLUSIONS Inflammatory infiltrates are frequently present in DCM explanted hearts. Although there are no relevant clinical variables to identify subclinical myocarditis, these patients are younger and have smaller ventricular diameters and poorer functional status at the time of transplantation.

Abstract
Staining protocols generally designed for the flow cytometric analysis of the cell cycle in mammalian cells are frequently not satisfactory for quantification of the various cell-cycle phases in yeasts. High CVs limit the accuracy of DNA content measurement and estimates of populations in cell-cycle compartments. This unit describes a staining procedure for yeasts using the sensitive nucleic acid stain SYBR Green I, which binds to double-stranded DNA with high selectivity and which has a much higher fluorescence quantum yield upon binding than most other commonly used fluorophores. The properties of this dye combined with optimized sample processing provide high-resolution DNA analysis, with half-peak CVs around 3 to 4% and clear-cut identification of the S phase.

Abstract
An analytical method based on ion-interaction chromatography with UV detection for simultaneous in-vitro estimation of the percutaneous absorption of the most used water-soluble UV filters in sunscreen cosmetics is proposed. These UV filters were phenylbenzimidazole sulfonic acid, disodium phenyl dibenzimidazole tetrasulfonate, benzophenone-4, and terephthalylidene dicamphor sulfonic acid. The methodology is based on applying the sunscreen containing the target UV filters to human epidermis in a diffusion cell. Analytes are determined in the receptor solution. To ensure skin integrity, screening of the cells was carried out by analytical determination of a marker. Analytical variables such as percentage ethanol, concentration of ion-pairing agent, pH of the mobile phase, and temperature were studied in order to achieve high resolution of the chromatographic peaks in the lowest possible time of analysis. The conditions selected consisted of a mobile phase composed of 35:65 (v/v) ethanol-ammonium acetate buffer solution (pH 4, containing 50 mmol L(-1) tetra-n-butylammonium bromide). The chromatographic determination was carried out with the analytical column at 50 degrees C. UV detection was carried out at the maximum absorption wavelength for each analyte. The limit of detection (3s(y/x)/b) ranged from 16 to 65 ng mL(-1), depending on the analyte.

Abstract
OBJECTIVE Comparison of outcomes of infants with respiratory distress syndrome (RDS), post-surfactant, extubated to synchronized nasal intermittent positive pressure ventilation (SNIPPV) or continued on conventional ventilation (CV). STUDY DESIGN Prospective post-surfactant randomized controlled trial of primary mode SNIPPV compared with CV in infants (born from July 2000 to March 2005) with birth weights (BW) of 600 to 1250 g. Primary mode SNIPPV was defined as its use in the acute phase of RDS, following the administration of the first dose of surfactant. RESULT There were no significant differences in the maternal demographics, antenatal steroid use, mode of delivery, BW, gestational age, gender or Apgar at 5 min between infants continued on CV (n=21) and those extubated to primary mode SNIPPV (n=20). Significantly, more babies in the CV group had the primary outcome of bronchopulmonary dysplasia (BPD)/death, compared to the SNIPPV group (52 versus 20%, P=0.03). There was no difference in the incidence of other common neonatal morbidities. There were no differences in the Mental or Psychomotor Developmental Index scores on follow-up between the two groups. CONCLUSION Infants of BW 600 to 1250 g with RDS receiving surfactant with early extubation to SNIPPV had a significantly lower incidence of BPD/death. Primary mode SNIPPV is a feasible method of ventilation in small premature infants.
