RESUMO
PURPOSE: To measure the clinical impact of the introduction of a reminder system for healthcare professionals to alert patients who are at risk for pressure ulcers (PU). METHODS: This was a pre- and post-test study of patients who were discharged from 6 medical-surgical units of the University Hospital of Fuenlabrada in 2009 and 2010. Beginning in January 2010, implementation of an on-screen list of reminders was automatically updated daily on the units' computers including patient arrival date, last assessment of ulceration risk and location of any PU. The cumulative incidence of PU was measured for patients discharged in 2009 (group A: healthcare professionals were not exposed to on-screen reminder) and 2010 (group B: healthcare professionals were exposed to on-screen reminder list). The relative risk (RR) was estimated. The study was completed with a stratified analysis and binary logistic regression. RESULTS: In group A, there were 84 cases of PU among 9263 patients discharged (0.9%); whereas in group B, there were 59 cases among 9220 patients discharged (0.6%). The RR of PU for group B/group A was 0.706 (p=0.038). In the logistic regression analysis, after adjusting for study variables, the odds ratio of PU B/A was 0.558. CONCLUSION: A list of on-screen reminders at the beginning of a healthcare professional's shift to inform them of patients at risk for developing a PU was effective at reducing the incidence of these clinical burdens.

The S100A12 protein was validated as a biomarker of health status in porcine saliva samples using a semi-quantitative approach based on Western blotting in four healthy and sixteen diseased animals, and in four animals with severe respiratory disease during three days of antibiotic therapy. Afterwards, a non-competitive sandwich immunoassay was then developed, validated, and used to quantify S100A12 in clinical porcine samples, using 14 healthy and 25 diseased pigs. Finally, the S100A12 concentrations in the saliva of ten pigs with respiratory disease were monitored during antibiotic therapy. Diseased animals showed higher concentrations of S100A12 than healthy animals, and the high concentrations of S100A12 in pigs with respiratory distress were reduced after antimicrobial therapy. The assay developed showed good precision and accuracy, as well as a low limit of detection of 3.19 ng/mL. It was possible to store saliva samples at -20 °C, or even at 4 °C, for two weeks before analysis without losing the validity of the results. The concentrations of S100A12 observed in serum and saliva samples showed a moderately positive association with a correlation coefficient of 0.48. The concentrations of the new validated biomarker S100A12 are highly associated with the novel salivary biomarker of inflammation, adenosine deaminase, and moderately to highly associated with the total oxidant status. The results reported in this study provide a new way of evaluating inflammatory diseases in pigs using saliva samples, which should be further explored for disease prevention and monitoring in the field.

BACKGROUND: Nurses credentialing as healthcare professionals commenced in Western Europe and in the USA by the end of the 19th and the beginning of the 20th century, boosted by the protestant reform movement. In Spain, it started in 1915, during the kingdom of Alfonso XIII (1902-1931). This historical period was marked by great political instability and big flaws in the healthcare delivery system. AIM: To describe the regulatory pathway that gave rise to the nursing profession in Spain, through official credentialing and regulation during the first third of the 20th century. METHOD: Documental, historical and regulatory documental research describing and analysing the national legislative sources used to regulate the professional development, as well as the education, training and competencies of the nursing practice in Spain, as compared with the developments in the European and American context. CONCLUSIONS: Professional development of the nursing profession in Western Europe and in the USA is consolidated during the 20th century as resulting in educational and training enhancement and the establishment of national and international professional bodies. In Spain, the regulatory and legal recognition of the nursing profession come into being in 1915 in response to a request from a female religious congregation.

BACKGROUND: Recently, the quantification of mitoses in cutaneous melanoma has been discharged from the main prognostic variables of the TNM classification. OBJECTIVE: To investigate the prognostic value of the presence of mitoses in primary cutaneous melanoma and to establish the number of mitoses per mm2 that may have prognostic significance. METHODS: A retrospective observational study was performed on 141 patients treated for cutaneous melanoma, who were assessed by the same pathologist, and who had a minimum follow-up of 2 years. Clinical, epidemiological, histopathological and follow-up variables were gathered and compared with the number of mitoses to distinguish the significance of differences by means of univariate, multivariate, and survival analyses. RESULTS: The cut-off level related to a better sensitivity and specificity was 1.50 mitoses per mm2. The presence of two or more mitoses/mm2 showed a better relationship with prognostic variables and both the overall and disease-free survival than the presence of 1 or more mitoses/mm2. This happens especially in melanomas thicker than 0.8 mm and it could affect the staging in cases with Breslow between 1 and 2 mm. CONCLUSIONS: A mitotic rate of two or more mitoses per mm2 in cutaneous melanoma should be considered as a more accurate prognostic factor than one or more mitoses per mm2, particularly in tumors equal or greater than 0.8 mm in thickness.

BACKGROUND: Delirium (acute brain dysfunction) is a potentially life threatening disturbance in brain function that frequently occurs in critically ill patients. While this area of brain dysfunction in critical care is rapidly advancing, striking limitations in use of terminology related to delirium internationally are hindering cross-talk and collaborative research. In the English literature, synonyms of delirium such as the Intensive Care Unit syndrome, acute brain dysfunction, acute brain failure, psychosis, confusion, and encephalopathy are widely used. This often leads to scientific "confusion" regarding published data and methodology within studies, which is further exacerbated by organizational, cultural and language barriers. OBJECTIVE: We undertook this multinational effort to identify conflicts in terminology and phenomenology of delirium to facilitate communication across medical disciplines and languages. METHODS: The evaluation of the terminology used for acute brain dysfunction was determined conducting communications with 24 authors from academic communities throughout countries/regions that speak the 13 variants of the Romanic languages included into this manuscript. RESULTS: In the 13 languages utilizing Romanic characters, included in this report, we identified the following terms used to define major types of acute brain dysfunction: coma, delirium, delirio, delirium tremens, délire, confusion mentale, delir, delier, Durchgangs-Syndrom, acute verwardheid, intensiv-psykose, IVA-psykos, IVA-syndrom, akutt konfusion/forvirring. Interestingly two terms are very consistent: 100 % of the selected languages use the term coma or koma to describe patients unresponsive to verbal and/or physical stimuli, and 100% use delirium tremens to define delirium due to alcohol withdrawal. Conversely, only 54% use the term delirium to indicate the disorder as defined by the DSM-IV as an acute change in mental status, inattention, disorganized thinking and altered level of consciousness. CONCLUSIONS: Attempts towards standardization in terminology, or at least awareness of differences across languages and specialties, will help cross-talk among clinicians and researchers.

Surgery is the cornerstone of treatment for resectable tumours of the oesophagus. Recent advances of surgical techniques and anaesthesiology have led to a substantial decrease in mortality and morbidity. Respiratory complications affect about 30% of patients after oesophagectomy and 80% of these complications occur within the first five days. Respiratory complications include sputum retention, pneumonia and ARDS. They are the major cause of morbidity and mortality after oesophageal resection and numerous studies have identified the factors associated with these complications. The mechanisms are not very different from those observed after pulmonary resection. Nevertheless, there is an important lack of definition, and evaluation of the incidence is particularly difficult. Furthermore, respiratory complications are related to many factors. Careful medical history, physical examination and pulmonary function testing help to identify the risk factors and provide strategies to reduce the risk of pulmonary complications. Standardized postoperative management and a better understanding of the pathogenesis of pulmonary complications are necessary to reduce hospital mortality. This article discusses preoperative, intraoperative, and postoperative factors affecting respiratory complications and strategies to reduce the incidence of these complications after oesophagectomy.

The objective of this work was to study the effect of small doses of naloxone (Nx) on the pulsatile secretion of prolactin (Pr). For this purpose 12 crossbreed ewes were selected and allocated to three groups of four. Group 1 was treated with two injections (at 7 and 19 h) of 40 microg of GnRH. Group 2 was treated with two i.m. injections (at 7 and 19 h) of 0.5mg of naloxone. And the control group 3 was sham treated with injections of 3 ml saline. Blood samples were taken at 20 min intervals during six consecutive hours after injections. When ewes were treated at 7h no significant changes were observed in concentrations of prolactin following treatment with GnRH. Values fluctuated between 200 and 210 ng/ml. In group 2 treated with naloxone there was no change in plasma Pr concentrations during the first 100 min of sampling, however 60 min after Nx treatment Pr decreased significantly (p<0.01) and thereafter Pr plasma levels were consistently less (p<0.001) than control and GnRH treated ewes for the duration of the experiment. The response of the three groups after the second injection (19 h): After the injection of GnRH plasma Pr levels followed much the same pattern observed after the initial treatment, Pr concentrations were similar to those of control ewes. Ewes treated with a second small dose of naloxone (0.5mg i.m.) however, showed a decrease in plasma Pr 60 min after the administration of the endogenous opioid antagonist. Thereafter Nx treated ewes had lesser (p<0.001) plasma Pr levels until the termination of the experiment. It was concluded that Nx an opioid antagonist administered in small intermittent doses can alter Pr plasma concentrations in the ewe, showing that endogenous opioids are important modulators of endocrine function and that the administration of small intermittent doses of opioid antagonists produce significant endocrine changes in ewes.

The aim of this study was to validate commercially available methods for porcine haptoglobin (Hp), C-reactive protein (CRP), serum amyloid A (SAA) and major acute phase protein (Pig-MAP) determinations. Intra and inter assay coefficients of variation (CVs) were lower than 20% in all cases with exception of inter assay CVs for CRP and Pig-MAP assays with samples of low acute phase proteins concentration, and for SAA assay at any acute phase proteins concentration. All methods showed good linearity and detection limits were low enough to detect APPs levels in healthy animals. Hp and SAA were very affected by haemolysis. Lipaemia influenced mainly on SAA determination. Over 15-fold increase was observed in CRP and SAA concentrations after artificially induced inflammation by a single subcutaneous dose of turpentine, whereas Hp and Pig-MAP increased less than 5-fold.

OBJECTIVE: To determine predictive factors of bronchial fistula following pneumonectomy. PATIENTS AND METHODS: In 14 years (1989-2003), we collect 58 cases of bronchial fistula following 725 consecutive pneumonectomy in the service of thoracic surgery of the Sainte Marguerite Hospital in Marseilles. There were 53 cases (91.4%) of cancers and 5 cases (8.6%) of various pathology. The average age of the patients was of 61 +/- 10 years (range 24 to 80 years). The sex ratio M/F was 8.7. The software of regression SPSS (version11.5) was used to identify the factors risk of a bronchial fistula after a univariate and multivariate analysis. RESULTS: The prevalence of the bronchial fistula after a pneumonectomy was 8%.The preoperative factors which increased to a significant degree the incidence of the bronchial dent to the univariate analysis were the chronic smoking (P < 0.001), the existence of COPD (P = 0.001) and of a previous thoracic surgery (P = 0.01). Operational data like a right- side pulmonary resection (P < 0.001), the type of bronchial stup carried out (P = 0.03) as and an extended pneumonectomy to the auricule (P = 0.03) were significant risk factors. With the logistic regression the significant risk factors were the chronic smoking (P = 0.002), the existence of COPD (P = 0.003), a previous pulmonary surgery (P = 0.03) and the right - side of the pneumonectomy (P < 0.001). The indication of the pneumonectomy was retained neither by the univariate analysis, nor by the logistic regression significant risk factors. CONCLUSION: The predictive factors of a bronchial fistula after a pneumonectomy are dominated by respiratory co-morbidities. To prevent this complication, we insist on the stop of the tobacco, a better respiratory preparation and the acquisition of a protocol adapted of the bronchial stub after a pneumonectomy particularly on the right side.

Objetivo: El objetivo de este estudio es comparar el abordaje laparoscópico convencional con el acceso por puerto único en el tratamiento quirúrgico del cáncer de endometrio. Materiales y métodos: Estudio retrospectivo sobre 36 pacientes, 18 operadas con técnica convencional y 18 con acceso por puerto único mediante una única incisión en la piel y 3 en la fascia, para la inserción de un trócar de 10mm y 2 de 5mm. Resultados: Se obtiene menor dolor postoperatorio (22,3% vs. 83,3%, p<0,001) y un mejor resultado estético (10 vs. 8, p=0,001) en el grupo de pacientes intervenidas por puerto único. El tiempo quirúrgico fue mayor en el grupo con técnica convencional (120 vs. 180min; p=0,027). En cuanto a estancia hospitalaria (2,5 vs. 2,5 días, p=0,69), pérdida sanguínea (1,15 vs. 1,25g/dl, p=1), número de ganglios extirpados (16,5 vs. 18; p=0,78) y complicaciones intra (0% vs. 5%, p=0,19) y posquirúrgicas (16,6% vs. 11,1%, p=0,63) no hubo diferencias significativas. Conclusión: El abordaje por puerto único es una técnica factible, segura y efectiva en el tratamiento del cáncer ginecológico, presentando una menor tasa de dolor postoperatorio y un mejor resultado estético.(AU)
Objective: The objective of this study is to compare conventional laparoscopy with transumbilical single-port access for the surgical treatment of endometrial cancer. Materials and methods: A retrospective study was performed with 36 patients, of whom 18 were operated using conventional laparoscopy, and 18 using a transumbilical single-port access (laparoendoscopic single-site surgery, or LESS) by making a single incision in the umbilical skin of 2-3cm, and 3 incisions in the fascia. One 10-mm trocar and two 5-mm trocars were inserted next to each other to access the abdominal cavity. Results: There were no statistical differences between groups in postoperative changes in haemoglobin concentration (1.15 vs. 1.25g/dL, P=1), hospital stay (2.5 vs. 2.5 days, P=.69), intraoperative complication rate (0% vs. 5%, P=.19), postoperative complications (16.6% vs. 11.1%, P=.63), number of pelvic lymph nodes (16.5 vs. 18, P=.78), and number of para-aortic lymph nodes (9 vs. 10, P=.64). Patients in the LESS group experienced less postoperative pain (22.3% vs. 83.3%, P<.001), and had a higher rate of satisfaction with the cosmetic results (10 vs. 8, P=.001). The median operating time was lower in the LESS group (120-180min, P=.027). Conclusion: Laparoendoscopic single-site surgery is a feasible, safety and effective technique for the treatment of endometrial cancer, with less postoperative pain and better cosmetic results.(AU)

BACKGROUND: The aim of this study was to analyze the results short term perioperative of patients with peritoneal surface malignancies undergoing cytoreduction with peritonectomy and HIPEC under a controlled fast track protocol and evaluate the factors related to the failure of implementation of the protocol. PATIENTS AND METHOD: We prospectively analyzed a consecutive series of patients (N = 156) with peritoneal surface malignancies treated by cytoreductive surgery with peritonectomy procedures and HIPEC from September 2008 until December 2014, in whom a fast track protocol was implemented. We limited the protocol to patients who had optimal cytoreduction, HIPEC administration, and not more than one digestive anastomosis. All patients signed informed consent for surgery and the perioperative multimodal recovery program. RESULTS: A total of 156 consecutive patients, with a median age of 57 years were included in the study. Median PCI was 8 (IQR: 0-32). Morbidity rate (Clavien-Dindo) was 25.6%, with a major morbidity rate (Clavien-Dindo III-IV) of 11.5%. One hundred and three patients (66%) completed the protocol. Multivariate analysis identified the following independent factors, which were related to failure of the protocol: age over 57 years (OR = 3.159, 95% CI: 1.286-7.758, p < 0.05), the realization of a digestive anastomosis (OR = 3.834, 95% CI: 1.562-9.414, p < 0.005) and occurrence of postoperative complications (OR = 18.704, 95% CI: 6.888-50.790, p < 0.001) CONCLUSIONS: Our data support the idea that in selected patients undergoing cytoreductive surgery and HIPEC, with a low PCI and especially no necessity to perform a digestive anastomosis, the implementation of a fast track program is feasible.

A protein constituent of the outer membrane from Neisseria meningitidis (hereafter called P64K) has been crystallized using the hanging drop technique. Crystals are tetragonal with unit cell dimensions a = b = 136.84 A and c = 78.44 A, compatible with a single monomer of 64 kDa in the asymmetric unit. When exposed to high intensity synchrotron radiation, these crystals diffract X-rays to at least 2.9 A resolution, indicating that a high resolution structure analysis is feasible.

The objective of the present study was to determine the effect of small doses of naloxone on sexual exhaustion in White New Zealand male rabbits. Twelve young and 12 adult male rabbits 6-12 months old and 14-20 months of age, respectively, were selected from a commercial farm. Each male rabbit was housed individually in galvanized cages (90 cm x 60 cm x 40 cm). The rabbits were housed in an open shed exposed to natural photoperiod (12 L 12 D, 19 degrees N). Daily temperature fluctuated through the year from 28 to 16 degrees C. Humidity was 45+/-5%. Water and food (rabbit chow PMI) was supplied ad libitum. After sexual behaviour for each studied group was established, the males were given a 6-day rest, and 3 days before next trial, six males of each group (treated) received a subcutaneous implant of 8 mg of naloxone in a crystalline nitrocellulose pellet formulated to be completely absorbed in 15 days. The remaining six males were sham-treated (control). At the end of the resting period as previously described, the sexual behavior of each group was studied and compared using a Mann-Whitney statistical U-test. The effect of naloxone on sexual behavior was analyzed with a Wilcoxon test for correlated samples. With regard to sexual activity between young and adult rabbits, it was observed that there was a significant difference between groups (P=0.00275, Z=2.8823, adjusted Z=2.99.43) showing that younger rabbits mounted/ejaculated from 9 to 10 females compared with 6 to 8 mounted/ejaculated by older rabbits. When naloxone was administered to both groups, there was a significant difference when comparing sexual behavior before and after administration of naloxone (table first and second trial). Young rabbits treated with naloxone mounted/ejaculated 11-12 females while older rabbits mounted nine females before reaching sexual exhaustion. A significant difference was observed when comparing the number of estrous females that were mounted/ejaculated between groups. Environmental photoperiod and temperature changes were not considered. It was concluded that endogenous opioids are important modulators of behavioral and hormonal interactions related to sexual behavior.

Existing evidence suggests that the presence of reward cues modifies the activity in attentional networks, however, the nature of these influences remains poorly understood. Here, we performed independent component analysis (ICA) in two fMRI datasets corresponding to two incentive delay tasks, which compared the response to reward (money and erotic pictures) and neutral cues, and yielded activations in the ventral striatum using a general linear model approach. Across both experiments, ICA revealed that both the right frontoparietal network and default mode network time courses were positively and negatively modulated by reward cues, respectively. Moreover, this dual neural response pattern was enhanced in individuals with strong reward sensitivity. Therefore, ICA may be a complementary tool to investigate the relevant role of attentional networks on reward processing, and to investigate reward sensitivity in normal and pathological populations.

Extrapancreatic tumor hypoglycemia (EPTH) is associated with increased amounts of high-molecular-weight precursor forms of insulin-like growth factor (IGF)-II ('big-IGF-II') that have a primary role in the pathophysiology of hypoglycemia. In the present study, using Western ligand and immunoblotting methods, we investigated IGF-binding proteins (IGFBPs), IGFBP-3 proteolysis and big-IGF-II in pre- and postoperative serum from two patients with EPTH due to benign pleural fibroma. In the preoperative serum, IGFBP-3 was reduced and IGFBP-2 was increased compared with that from an age-matched healthy control. IGFBP-3 proteolysis was dramatically reduced in one patient, whereas no major alteration was observed in the other (9% and 120% of control serum, respectively). IGFBPs progressively returned to a subnormal pattern in postoperative serum, whereas IGFBP- 3 proteolysis remained greater than in preoperative serum in both patients at days 14 and 90 after surgery. High-molecular-weight forms of IGF-II predominate in EPTH serum (65% and 57% of total IGF-II immunoreactivity in patients 1 and 2, respectively, compared with 2 5% in control serum). Two forms, of molecular mass 10 and 12 kDa ('standard big-IGF-II') were present in both EPTH and control sera, whereas two additional forms, of molecular mass 15 and 18 kDa ('big big-IGF-II') were observed in EPTH sera only. Big big-IGF-II represented 72% and 55% of total high-molecular-weight forms of IGF-II in the two EPTH sera, respectively. All big forms of IGF-II disappeared from the serum as early as 6 h after surgery. This study shows that combination of simple Western blotting methods, available routinely in most laboratories, should prove useful in providing reliable physiopathological information in EPTH.

Post-transplant lymphoproliferative disease is a complication of bone marrow and solid organ transplantation, mostly associated with Epstein-Barr virus infection and chronic immunosuppression. Even if spontaneous resolution after cessation of immunosuppressive therapy can be observed, the prognosis of this disorder is usually poor with a low response to specific treatment. We describe a case of B-cell lymphoma of the nasopharynx occurring 6 months after double-lung transplantation. In spite of its monoclonal nature, anti-CD 20 monoclonal antibody given in the presence of reduced immunosuppression resulted in a complete response. The patient also received "consolidation" radiation therapy to prevent the recurrence. The treatment was well tolerated with minimal side effects. The patient was asymptomatic and had a well functioning graft more than 1 year after therapy.

The aim of this study was to evaluate the incidence of postoperative lymphocytotoxic antibodies (LA) formation and to assess their potential utility in immunologic monitoring after lung transplantation. We determined prospectively the percentage LA against a reference panel reactive antibody in a complement-dependent microlymphocytotoxicity test in 137 sequential serum samples obtained from 14 consecutive lung transplant recipients who survived over the first postoperative year. Four patients developed high titers of LA (greater than 10% panel reactive antibody reactivity in at least 3 consecutive samples) by 2 to 24 months after surgery. Antibodies were mostly immunoglobulin M isotype, without any specificity against the donor's human leukocyte antigen and were correlated with the development of bronchiolitis obliterans syndrome (p=.01) and with chronic bronchial infectious colonization (p=.03). In conclusion, a polyclonal immunoglobulin M antibody production can be detected in serum samples from lung transplant recipients and seems to be involved in the progression of chronic rejection process. These preliminary results incline to carry on the cytotoxicity screening of a panel of lymphocytes to better understand the significance of such reactivity.

BACKGROUND: In contrast to the use of the stomach as an esophageal substitute, the use of the colon is becoming uncommon. METHODS: From 1985 to 1995, 60 patients underwent colon interposition for esophageal cancer (n = 37), benign stricture (n = 13), iatrogenic fistula (n = 5), achalasia (n = 3), or necrosis of a previous substitute (n = 2). A long isoperistaltic conduit based on the left colonic artery could be used in 52 patients (86.7%). The surgical route used was through the esophageal bed in 38 patients (63.3%), under the sternum in 21 patients, and under the skin in 1 patient. RESULTS: Colon interposition represented 18.5% of all operations performed for esophageal substitution during the study period. The choice of the colon resulted from an inadequate stomach in 33 cases (55%). The operative mortality rate was 8.3%. Seven patients (13.5%) required dilation of the esophagocolonic anastomosis. At last follow-up, 34 patients (65.4%) had no difficulty eating. Multivariate analysis identified the conduit position in the posterior mediastinum as the sole independent predictor of a good functional result (p = 0.002). CONCLUSIONS: Colon interposition for esophageal substitution, usually performed when the stomach is not available, provides satisfactory function when placed in the esophageal bed.

Isolated absence of a pulmonary artery is an exceptional cause of massive hemoptysis. We report a 35-year-old woman with agenesis of the left pulmonary artery who presented with exsanguinating hemoptysis that prompted angiography with the aim to embolize the bleeding vessels selectively. The procedure could not be completed because of the presence of an anterior spinal artery branching from the aberrant systemic-to-pulmonary circulation. The patient successfully underwent an emergent pneumonectomy.
