The effects of sevoflurane and halothane anesthesia on cerebral blood flow velocity in children.

We compared cerebral blood flow velocity during anesthesia with sevoflurane and halothane in 23 children admitted for elective surgery (age, 0.4-9.7 yr; median age, 1.9 yr; ASA physical status I-II). Inhaled induction was performed in a randomized sequence with sevoflurane or halothane. Under steady-state conditions, cerebral blood flow velocity (systolic [V(s)], mean [V(mn)], and diastolic [VD]) were measured by a blinded investigator using transcranial pulsed Doppler ultrasonography. The anesthetic was then changed. CBFV measurements were repeated after washout of the first anesthetic and after steady-state of the second (equivalent minimal alveolar concentration to first anesthetic). The resistance index was calculated. VD and V(mn) were significantly lower during sevoflurane (V(mn) 1.35 m/s) than during halothane (V(mn) 1.50 m/s; P = 0.001), whereas V(s) was unchanged. The resistance index was lower during halothane (P < 0.001). Our results indicate lower vessel resistance and higher mean velocity during halothane than during sevoflurane. IMPLICATIONS: The mean cerebral blood flow velocity is significantly decreased in children during inhaled anesthesia with sevoflurane than during halothane. This might be relevant for the choice of anesthetic in children with risk of increased intracranial pressure, neurosurgery, or craniofacial osteotomies.

Defectos paradójicos en regiones con necrosis miocárdica. análisis mediante gated-spect de perfusión miocárdica.

Objectius: Valorar el significat dels defectes paradoxals (DP) segmentaris (captació en esforç més gran que en repòs) a la gated-SPECT (Single Photon Emission Computer Tomography) de perfusió miocàrdica amb compostos tecneciats en regions amb necrosi miocàrdica. Material i mètodes: Es van revisar 1764 SPECT de perfusió miocàrdica estrès-repòs consecutives de pacients amb infart (IM) previ i es van identificar 117 pacients (6,6%) en els quals els DPs corresponien a una regió amb necrosi miocàrdica. Es van valorar els criteris gammagràfics de viabilitat (intensitat del defecte, valor d'aquesta intensitat ponderat pel nombre de segments compromesos-VIP-, la motilitat i l'engrossiment miocàrdic sistòlic) en els segments d'aquestes regions i les característiques de l'artèria responsable en els 96 pacients en els quals s'havia practicat una coronariografia. Resultats: Es van analitzar 160 necrosis, 125 (75%) paradoxals (67 (54%) en regió AnteroSeptoApical i 58 (46%) en regió InferoLateral) i 35 (25%) no paradoxals (19 (54%) ASA i 16 ( 46%) IL). Els valors de severitat de la necrosi i del VIP van ser inferiors en l'estudi d'estrès respecte al repòs i la diferència d'aquests va ser sempre negativa, evidenciant un comportament gammagràfic paradoxal. Per contra, aquests valors van ser inferiors al repòs respecte a l'estrès en les necrosi no paradoxals posant de manifest un comportament gammagràfic de mínima o nul reversibilitat. Així mateix, es van trobar alteracions lleus en la motilitat i engrossiment de les necrosi paradoxals i moderats en les necrosi no paradoxals. Es van trobar 102 necrosis amb DP i coronariografia dels quals, 84 (88%) tenien permeabilitat a l'artèria responsable de la necrosi i 12 pacients (12%) tenien circulació colateral per compensar l'oclusió de l'artèria responsable. Conclusions: Tots els segments amb DP en regions amb necrosi complien criteris gammagràfics de viabilitat en les imatges d'estrès, considerant aquestes imatges millors per a l'avaluació d'aquest tipus de lesions. El vas responsable de la regió amb DP es trobava permeable o bé presentava circulació colateral evident en els casos en què la coronària es trobava closa.

Efectos sobre la calidad de la inducción anestésica y agitación postoperatoria en niños según la presencia paterna en el quirófano

La presència paterna com una intervenció no farmacològica per a reduïr l’estrés i millorar la cooperació infantil durant la inducció anestèsica ha estat freqüentment estudiada, sobretot als països anglosaxons, amb resultats contradictoris. L’objectiu del present estudi és avaluar la qualitat de la inducció anestèsica i del postoperatori segons la presència paterna o no a la mateixa en xiquets espanyols, ASA I-II, no premedicats, programats per a cirurgía otorrinolaringológica. Hem trobat un increment de la incidència d’inducció suau i una disminució de la inducció traumàtica al grup de xiquets amb presència paterna (p&0.05).

The gap between scientific evidence and clinical practice : 5-aminosalicylates are frequently used for the treatment of Crohn's disease

BACKGROUND: There is uncertain evidence of effectiveness of 5-aminosalicylates (5-ASA) to induce and maintain response and remission of active Crohn's disease (CD), and weak evidence to support their use in post-operative CD. AIM: To assess the frequency and determinants of 5-ASA use in CD patients and to evaluate the physicians' perception of clinical response and side effects to 5-ASA. METHODS: Data from the Swiss Inflammatory Bowel Disease Cohort, which collects data since 2006 on a large sample of IBD patients, were analysed. Information from questionnaires regarding utilisation of treatments and perception of response to 5-ASA were evaluated. Logistic regression modelling was performed to identify factors associated with 5-ASA use. RESULTS: Of 1420 CD patients, 835 (59%) were ever treated with 5-ASA from diagnosis to latest follow-up. Disease duration >10 years and colonic location were both significantly associated with 5-ASA use. 5-ASA treatment was judged to be successful in 46% (378/825) of treatment episodes (physician global assessment). Side effects prompting stop of therapy were found in 12% (98/825) episodes in which 5-ASA had been stopped. CONCLUSIONS: 5-Aminosalicylates were frequently prescribed in patients with Crohn's disease in the Swiss IBD cohort. This observation stands in contrast to the scientific evidence demonstrating a very limited role of 5-ASA compounds in the treatment of Crohn's disease.

The occurrence of intra-operative hypotension varies between hospitals: observational analysis of over 147000 anaesthesia

Background: Hypotension, a common intra-operative incident, bears an important potential for morbidity. It is most often manageable and sometimes preventable, which renders its study important. Therefore, we aimed at examining hospital variations in the occurrence of intraoperative hypotension and its predictors. As secondary endpoints, we determined to what extent hypotension relates to the risk of postoperative incidents and death. Methods: We used the Anaesthesia Databank Switzerland, built on routinely and prospectively collected data on all anaesthesias in 21 hospitals. The three outcomes were assessed using multi-level logistic regression models. Results: Among 147573 anaesthesia, hypotension ranged from 0.6 to 5.2% in participating hospitals, and from 0.3 up to 12% in different surgical specialties. Most (73.4%) were minor single events. Age, ASA status, combined general and regional anaesthesia techniques, duration of surgery, and hospitalization were significantly associated to hypotension. Although significantly associated, the emergency status of the surgery had a weaker effect. Hospitals' Odds Ratios for hypotension varied between 0.12 to 2.50 (p ≤0.001) with respect to the mean prevalence of 3.1%, even after adjusting for patient and anaesthesia factors, and for type of surgery. At least one postoperative incident occurred in 9.7% of the interventions, including 0.03% deaths. Intra-operative hypotension was associated with higher risk of post-operative incidents and death. Conclusions: Wide variations in the occurrence of hypotension amongst hospitals remain after adjustment for risk factors. Although differential reporting from hospitals may exist, variations in anesthesia techniques and blood pressure maintenance could have also contributed. Intra-operative hypotension is associated with morbidities and sometimes death, and constant vigilance must thus be advocated.

Bacterial and fungal colonization of burn wounds

A prospective study of fungal and bacterial flora of burn wounds was carried out from February 2004 to February 2005 at the Burns Unit of Hospital Regional da Asa Norte, Brasília, Brazil. During the period of the study, 203 patients were treated at the Burns Unit. Wound swab cultures were assessed at weekly intervals for four weeks. Three hundred and fifty four sampling procedures (surface swabs) were performed from the burn wounds. The study revealed that bacterial colonization reached 86.6% within the first week. Although the gram-negative organisms, as a group, were more predominant, Staphylococcus aureus (28.4%) was the most prevalent organism in the first week. It was however surpassed by Pseudomonas aeruginosa form third week onwards. For S. aureus and P. aeruginosa vancomycin and polymyxin were found to be the most effective drugs. Most of the isolates showed high level resistance to antimicrobial agents. Fungi were found to colonize the burn wound late during the second week postburn, with a peak incidence during the third and fourth weeks. Species identification of fungi revealed that Candida tropicalis was the most predominant, followed by Candida parapsilosis. It is crucial for every burn institution to determine the specific pattern of burn wound microbial colonization, the time-related changes in the dominant flora, and the antimicrobial sensitivity profiles. This would enable early treatment of imminent septic episodes with proper empirical systemic antibiotics, without waiting for culture results, thus improving the overall infection-related morbidity and mortality.

“Unmixing” Tissue Gene Expression Signatures from Tumor Biopsies

Emergent molecular measurement methods, such as DNA microarray, qRTPCR, andmany others, offer tremendous promise for the personalized treatment of cancer. Thesetechnologies measure the amount of specific proteins, RNA, DNA or other moleculartargets from tumor specimens with the goal of “fingerprinting” individual cancers. Tumorspecimens are heterogeneous; an individual specimen typically contains unknownamounts of multiple tissues types. Thus, the measured molecular concentrations resultfrom an unknown mixture of tissue types, and must be normalized to account for thecomposition of the mixture.For example, a breast tumor biopsy may contain normal, dysplastic and cancerousepithelial cells, as well as stromal components (fatty and connective tissue) and bloodand lymphatic vessels. Our diagnostic interest focuses solely on the dysplastic andcancerous epithelial cells. The remaining tissue components serve to “contaminate”the signal of interest. The proportion of each of the tissue components changes asa function of patient characteristics (e.g., age), and varies spatially across the tumorregion. Because each of the tissue components produces a different molecular signature,and the amount of each tissue type is specimen dependent, we must estimate the tissuecomposition of the specimen, and adjust the molecular signal for this composition.Using the idea of a chemical mass balance, we consider the total measured concentrationsto be a weighted sum of the individual tissue signatures, where weightsare determined by the relative amounts of the different tissue types. We develop acompositional source apportionment model to estimate the relative amounts of tissuecomponents in a tumor specimen. We then use these estimates to infer the tissuespecificconcentrations of key molecular targets for sub-typing individual tumors. Weanticipate these specific measurements will greatly improve our ability to discriminatebetween different classes of tumors, and allow more precise matching of each patient tothe appropriate treatment

Evaluation of the GlideScope (R) for tracheal intubation in patients with cervical spine immobilization by a semi-rigid collar

Background: In patients with cervical spine injury, a cervical collar may prevent cervical spine movements but renders tracheal intubation with a standard laryngoscope difficult if not impossible. We hypothesized that despite the presence of a semi-rigid cervical collar and with the patient's head taped to the trolley, we would be able to intubate all patients with the GlideScopeR and its dedicated stylet. Methods: 50 adult patients (ASA 1 or 2, BMI ≤35 kg/m2) scheduled for elective surgical procedures requiring tracheal intubation were included. After standardized induction of general anesthesia and neuromuscular blockade, the neck was immobilized with an appropriately sized semi-rigid Philadelphia Patriot® cervical collar, the head was taped to the trolley. Laryngoscopy was attempted using a Macintosh laryngoscope blade 4 and the modified Cormack Lehane grade was noted. Subsequently, laryngoscopy with the GlideScopeR was graded and followed by oro-tracheal intubation. Results: All patients were successfully intubated with the GlideScopeR and its dedicated stylet. The median intubation time was 50 sec [43; 61]. The modified Cormack Lehane grade was 3 or 4 at direct laryngoscopy. It was significantly reduced with the GlideScopeR (p <0.0001), reaching 2a in most of patients. Maximal mouth opening was significantly reduced with the cervical collar applied, 4.5 cm [4.5; 5.0] vs. 2.0 cm [1.8; 2.0] (p <0.0001). Conclusions: The GlideScope® allows oro-tracheal intubation in patients having their cervical spine immobilized by a semi-rigid collar and their head taped to the trolley. It furthermore decreases significantly the modified Cormack Lehane grade.

Implication of the endocannabinoid system in the locomotor hyperactivity associated with congenital hypothyroidism

Alterations in motor functions are well-characterized features observed in humans and experimental animals subjected to thyroid hormone dysfunctions during development. Here we show that congenitally hypothyroid rats display hyperactivity in the adult life. This phenotype was associated with a decreased content of cannabinoid receptor type 1 (CB(1)) mRNA in the striatum and a reduction in the number of binding sites in both striatum and projection areas. These findings suggest that hyperactivity may be the consequence of a thyroid hormone deficiency-induced removal of the endocannabinoid tone, normally acting as a brake for hyperactivity at the basal ganglia. In agreement with the decrease in CB(1) receptor gene expression, a lower cannabinoid response, measured by biochemical, genetic and behavioral parameters, was observed in the hypothyroid animals. Finally, both CB(1) receptor gene expression and the biochemical and behavioral dysfunctions found in the hypothyroid animals were improved after a thyroid hormone replacement treatment. Thus, the present study suggests that impairment in the endocannabinoid system can underlay the hyperactive phenotype associated with hypothyroidism.

Ulcerative colitis impairs the acylethanolamide-based anti-inflammatory system reversal by 5-aminosalicylic acid and glucocorticoids

Studies in animal models and humans suggest anti-inflammatory roles on the N acylethanolamide (NAE)-peroxisome proliferators activated receptor alpha (PPARα) system in inflammatory bowel diseases. However, the presence and function of NAE-PPARα signaling system in the ulcerative colitis (UC) of humans remain unknown as well as its response to active anti-inflammatory therapies such as 5-aminosalicylic acid (5-ASA) and glucocorticoids. Expression of PPARα receptor and PPARα ligands-biosynthetic (NAPE-PLD) and -degrading (FAAH and NAAA) enzymes were analyzed in untreated active and 5-ASA/glucocorticoids/immunomodulators-treated quiescent UC patients compared to healthy human colonic tissue by RT-PCR and immunohistochemical analyses. PPARα, NAAA, NAPE-PLD and FAAH showed differential distributions in the colonic epithelium, lamina propria, smooth muscle and enteric plexus. Gene expression analysis indicated a decrease of PPARα, PPARγ and NAAA, and an increase of FAAH and iNOS in the active colitis mucosa. Immunohistochemical expression in active colitis epithelium confirmed a PPARα decrease, but showed a sharp NAAA increase and a NAPE-PLD decrease, which were partially restored to control levels after treatment. We also characterized the immune cells of the UC mucosa infiltrate. We detected a decreased number of NAAA-positive and an increased number of FAAH-positive immune cells in active UC, which were partially restored to control levels after treatment. NAE-PPARα signaling system is impaired during active UC and 5-ASA/glucocorticoids treatment restored its normal expression. Since 5-ASA actions may work through PPARα and glucocorticoids through NAE-producing/degrading enzymes, the use of PPARα agonists or FAAH/NAAA blockers that increases endogenous PPARα ligands may yield similar therapeutics advantages.

Is the effect of inguinal field block with 0.5 % bupivacaine on postoperative pain after hernia repair enhanced by addition of ketorolac or S(+) ketamine ?

Résumé Malgré l'apparition de nouvelles techniques chirurgicales dites « sans tension », l'antalgie post-opératoire après cure de hernie inguinale reste un défi pour les anesthésiologistes. Récemment on a suggéré que l'addition de ketamine ou d'un anti-inflammatoire non-stéroïdien (AINS) à un anesthésique local pourrait améliorer et prolonger l'analgésie postopératoire. Le but de cette étude, à laquelle ont participé 36 patients ASA I-II, était d'évaluer si la coadministration de S(+) ketamine ou de ketorolac renforcerait les effets analgésiques de la bupivacaïne après cure ambulatoire de hernie inguinale sous anesthésie générale. L'analgésie a consisté en une infiltration de la plaie associé à un bloc inguinal avec soit 30 ml de bupivacaïne 0,5 % (n=12), soit 27 ml de bupivacaïne 0,5 % + 3 ml de S(+) ketamine (75 mg) (n=12), soit 28 ml de bupivacaïne 0,5 % + 2 ml de ketorolac (60 mg) (n=12). La prise orale d'antalgique en phase postopératoire était standardisée. L'intensité des douleurs a été évaluée au moyen d'une échelle visuelle analogique (EVA), d'un score verbal d'estimation et par algométrie de pression respectivement 2, 4, 6, 24 et 48 heures après l'intervention. Les trois groupes de patients ont présenté le score de douleur évalué par EVA le plus élevé à 24 heures, score significativement différent de ceux mesurés à 6 et 48 heures (P <0.05). A part une sensation de douleurs significativement moindre (score verbal d'estimation) dans le groupe ketorolac à 24 et 48 heures et seulement à 48 heures dans le groupe ketamine, il n'y avait aucune autre différence entre les groupes pour la durée de l'étude (48 heures) en ce qui concerne les scores de douleur, les seuils de douleur à la pression ou la prise postopératoire d'antalgiques « de secours ». En conclusion, l'addition de S(+) ketamine ou de ketorolac, n'améliore que marginalement l'effet analgésique de la bupivacaïne. Ceci peut-être mis en relation avec la technique de cure de hernie « sans tension » induisant un bas niveau de douleur postopératoire. Abstract Objective: The aim of the study was to assess whether coadministration of S(±) ketamine or ketorolac would enhance or prolong local analgesic effect of bupivacaine after inguinal hernia repair. Design: Prospective double-blind randomized study evaluating pain intensity after surgery under general anesthesia. Setting: Outpatient facilities of the University Hospital of Lausanne. Patient: Thirty-six ASA I-II outpatients scheduled for elective day-case inguinal herniorraphy. Intervention: Analgesia strategy consisted of a wound infiltration and an inguinal field block either with 30 mL bupivacairie (0.5%) or with the same volume of a mixture of 27 mL bupivacaine (0.5%) + 3 mL S(+) ketamine (75 mg) or a 28 mL bupivacaine (0.5%) + 2 ML ketorolac (60 mg). Postoperative analgesic regimen was standardized. Outcome Measures: Pain intensity was assessed with a Visual Analog Seale, a verbal rating score, and by pressure algometry 2, 4, 6, 24, and 48 hours after surgery. Results: The 3 groups of patients experienced the highest Visual Analog Scale pain score at 24 hours, which was different from those at 6 and 48 hours (P < 0.05). Apart from a significantly lower pain sensation (verbal rating score) in the ketorolac group at 24 and 48 hours and only at 48 hours with ketamine, there were no other differences in pain scores, pain pressure thresholds, or rescue analgesic consumption between groups throughout the 48-hour study period. Conclusion: The addition of S (+)-ketamine or ketorolac only minimally improves the analgesic effect of bupivacaine. This may be related to the tension-free hernia repair technique associated with low postoperative pain.

Monitoring of sedation during neuroaxial blockade.

Abstract Study objective: The arousal state changes during spinal anesthesia. It is not clear if BIS and others devices could monitor the induced neuroaxial blockade sedation. Our objective was evaluate BIS and entropy values when spinal anesthesia is done. Design: We developed a prospective study. Patients: 40 patients were included in this study, ASA I-III, over 60 years old, undergoing spinal anesthesia, without premedication scheduled for orthopedics procedures. Intervention: Spinal anesthesia was performed with the unseated volunteer in the lateral decubitus position with a 25-gauge Whitacre needle at L2-L3 space, andanesthesia was done with 12 mg of 0.5% hyperbaric bupivacaine. Patients were positioned supine for 5 min after spinal anesthesia. Measurements: Observer’s Assessment of Alertness/Sedation OAA/S, response (RE) and state entropy (SE) and BIS, and standard hemodynamic measures. Main results: Statistical analysis were performed by Wilcoxon test or ANOVA, p<0.05 was considered statistically significant.RE and BIS showed a better correlation with the OAA/S scale values (Pk 0.81 and 0.82) than SE (Pk 0.69). The OAA/S, RE and SE showed significative differences from basal values after 30 min of neuroaxial anesthesia (ANOVA p<0.05). BIS showed differences after 40 min (ANOVA p<0.05). There were no differences between BIS and RE values along the study (ANOVA p>0.05). Conclusions: The spinal anesthesia decreased the cortical activity and these were founded by OAA/S scale and depth anesthetics monitors. OAA/S was a more sensitive value of this induced sedation. BIS and RE showed a better correlation with OAA/S scale than SE.

El paciente Nonagenario con Fractura de fémur

Introducción: Los nonagenarios son un grupo aún reducido, pero en expansión, se estima que en el año 2050 la población anciana en España alcance el 35,7% de la población, aumentando así su importancia relativa y planteando un importante desafío de salud pública Ellos tienen varias particularidades que hay que considerar para planificar futuras estrategias de atención especialmente en el acto quirúrgico dentro del que se calcula que el 3% requerirá en este periodo de vida una intervención quirúrgica por fractura de fémur. Objetivo: Realizamos un estudio retrospectivo de una serie de casos en el que se comparan características de pacientes nonagenarios que requieren intervención quirúrgica por fractura de fémur con un grupo de pacientes octogenarios sometidos a la misma intervención Métodos: Estudio retrospectivo de 100 pacientes programados para cirugía por fractura de fémur en HSCSP, distribuidos en dos grupos de edad grupo 1 mayores o igual a 90 años y grupo 2 ancianos menores o igual de 89 años en el que se recogen datos preoperatorios, intraoperatorios y postoperatorios Resultados: Se incluyeron 100 pacientes divididos en dos grupos, grupo 1 n:50 pacientes mayores de 90 años con un 72% de mujeres, y un promedio de edad de 93.3 años, el grupo 2 n:50 pacientes con edad entre 80 y 89 años con un promedio de 81.1 años de los cuales 78% fueron mujeres y 22% hombres, las patologías más frecuentes en los dos grupos en el momento del preoperatorio fueron HTA 71%, Dislipemia 27% y demencia en un 24%, el 54% de los pacientes nonagenarios fueron clasificados como ASA III, mientras que el grupo 2 el mayor porcentaje (38%) fue ASA IV, El grupo 1 fue intervenido quirúrgicamente en promedio a los 3.12 días del ingreso, el grupo 2 a los 6.9 días, en total promedio de estancia hospitalaria fueron 11.3 días en los pacientes nonagenarios y 15.8 en los pacientes menores de 89 años. Respecto a la mortalidad a 1 mes no hay diferencias entre los dos grupos. Conclusiones Los pacientes mayores de 90 años clasificados como ASA II-III, serán siempre considerados como candidatos a procedimientos quirúrgicos dado que no presentan mayor comorbilidad que pacientes menores y la edad como único factor no es un factor excluyente para la intervención quirúrgica.

Surgery for incarcerated hernia: short-term outcome with or without mesh.

BACKGROUND: Incarcerated hernias represent about 5-15 % of all operated hernias. Tension-free mesh is the preferred technique for elective surgery due to low recurrence rates. There is however currently no consensus on the use of mesh for the treatment of incarcerated hernias, especially in case of bowel resection. AIM: The aims of this study were (i) to report our current practice for the treatment of incarcerated hernias, (ii) to identify risk factors for postoperative complications, and (iii) to assess the safety of mesh placement in potentially infected surgical fields. METHODS: This retrospective study included 166 consecutive patients who underwent emergency surgery for incarcerated hernia between January 2007 and January 2012 in two university hospitals. Demographics, surgical details, and short-term outcome were collected. Univariate analysis was employed to identify risk factors for overall, infectious, and major complications. RESULTS: Eighty-four patients (50.6 %) presented inguinal hernias, 43 femoral (25.9 %), 37 umbilical hernias (22.3 %), and 2 mixed hernias (1.2 %), respectively. Mesh was placed in 64 patients (38.5 %), including 5 patients with concomitant bowel resection. Overall morbidity occurred in 56 patients (32.7 %), and 8 patients (4.8 %) developed surgical site infections (SSI). Univariate risk factors for overall complications were ASA grade 3/4 (P = 0.03), diabetes (P = 0.05), cardiopathy (P = 0.001), aspirin use (P = 0.023), and bowel resection (P = 0.001) which was also the only identified risk factor for SSI (P = 0.03). In multivariate analysis, only bowel incarceration was associated with a higher rate of major morbidity (OR = 14.04; P = 0.01). CONCLUSION: Morbidity after surgery for incarcerated hernia remains high and depends on comorbidities and surgical presentation. The use of mesh could become current practice even in case of bowel resection.

The evolution of universities' relations with the business sector in Brazil: What national publications between 1980 and 2012 reveal

ABSTRACT This paper addresses the changes in university-industry relations in Brazil regarding innovation activities. It is based on a survey of articles published in major national journals or presented at the most relevant Brazilian and regional conferences, between 1980 and 2012. The year 1980 was chosen due to the creation of the Technological Innovation Offices (NITs), which was the first government initiative to encourage knowledge transfer from universities to companies; the second was the Innovation Act of 2004. Our assumption was that after the Act the number of academic papers on this subject would increase, bringing new ideas and propositions of models to enhance this relationship. The methodology employed a qualitative, exploratory approach, using bibliographical research and a bibliometric analysis of 247 papers. Literature review of international studies shows the discussion of problems and suggestions for improvements, while in Brazil there is still a debate on whether this collaboration should occur, and if this is a legitimate role for the university. Despite the numerical growth, the content analysis showed few papers on new configurations and procedures for partnership management. We conclude that university-industry relations are not a regular and totally accepted process in Brazilian public universities, which reflect an ideological bias against cooperation with firms.
