Cannabis use influence on peripheral brain-derived neurotrophic factor levels in antipsychotic-naïve first-episode psychosis.

The objective of this study is to determine whether cannabis influences BDNF levels in patients with psychosis (FEP) and healthy volunteers (HV) to help understand the role of BDNF in psychosis. We assessed the association between BDNF and cannabis in a cohort of FEP antipsychotic-naïve patients and HV, whilst controlling for other potential confounding factors. 70 FEP drug-naive patients and 57 HV were recruited. A sociodemographic variable collection, structured clinical interview, weight and height measurement, substance use determination, and blood collection to determine BDNF levels by ELISA analysis were done. In FEP patients, cannabis use was associated with BDNF levels (high cannabis use was associated with lower BDNF levels). Moreover, cannabis use was statistically significantly associated with age (high use of cannabis was associated with younger age). In HV, no relationship between cannabis use and BDNF levels was observed. Otherwise, cannabis use was significantly associated with tobacco use, so that high cannabis users were also high tobacco users. This study showed a different association between cannabis use and BDNF levels in FEP patients compared with HV, particularly, with high doses of cannabis. These findings may help understand the deleterious effects of cannabis in some vulnerable individuals, as well as discrepancies in the literature.

Trends in AIDS Mortality, Retention in Opioid Agonist Therapy, and HIV RNA Suppression in HIV-Infected People Who Injected Drugs from 2000 to 2015.

AIDS is a major cause of preventable mortality in HIV-infected people who inject drugs (HIV-PWID). An observational study was conducted to examine trends in AIDS mortality and related factors among HIV-infected individuals who died between 2000 and 2015 at an urban hospital. Overall HIV-mortality was 6.5% (413/6307) with no changes over time (p 0.76). AIDS mortality dropped in HIV-PWID (p 0.02) although it represented 26.4% at the end of study period. Age (per one-year increase) [odds ratio (OR) 0.95], third study period (2010-2015) (OR 0.54), HIV-PWID on opioid agonist therapy (OAT) (OR 0.39), and HIV RNA suppression (OR 0.15) were associated with AIDS mortality. OAT was reported in 58.3% (161/276) and RNA suppression in 30.9% (85/276) of HIV-PWID. OAT non-retention was due to drop-outs [85.2% (98/115)] and rejection [14.8% (17/115)] in HIV-PWID. Therefore, additional strategies are required to improve OAT retention and HIV RNA suppression to continue reducing AIDS mortality.

Adipose tissue and serum CCDC80 in obesity and its association with related metabolic disease.

Coiled-coil domain-containing 80 (CCDC80) is an adipocyte-secreted protein that modulates glucose homeostasis in response to diet-induced obesity in mice. The objective of this study is to analyze the link between human CCDC80 and obesity. CCDC80 protein expression was assessed in paired visceral (VAT) and subcutaneous (SAT) adipose tissue from 10 subjects (BMI range 22.4-38.8 kg/m2). Circulating CCDC80 levels were quantified in serum samples from two independent cross-sectional cohorts comprising 33 lean and 15 obese (cohort 1) and 32 morbid obese (cohort 2) male subjects. Insulin sensitivity, insulin secretion and blood neutrophil count were quantified in serum samples from both cohorts. Additionally, circulating free IGF-1 levels and oral glucose tolerance tests (OGTT) were assessed in cohort 1 whereas C-reactive protein levels and degree of atherosclerosis and hepatic steatosis were studied in cohort 2. In lean subjects, total CCDC80 protein content assessed by immunoblotting was lower in VAT than in SAT. In obese patients, CCDC80 was increased in VAT (P<0.05), but equivalent in SAT compared with lean counterparts. In cohort 1, serum CCDC80 correlated negatively with the acute insulin response to glucose and IGF1 levels, and positively with blood neutrophil count, independently of BMI, but not with insulin sensitivity. In cohort 2, serum CCDC80 was positively linked to the inflammatory biomarker C-reactive protein (r=0.46; P=0.009), atherosclerosis (carotid intima-media thickness, r=0.62; P<0.001) and hepatic steatosis (ANOVA P=0.025). Overall, these results suggest for the first time that CCDC80 may be a component of the obesity-altered secretome in VAT and could act as an adipokine whose circulant levels are linked to glucose tolerance derangements and related to inflammation-associated chronic complications.

Systemic strengths and needs in palliative home care: exploring complexity.

OBJECTIVE: We aimed to investigate the relationship between systemic strengths and complexity in home care of end-of-life patients. METHODS: Quantitative descriptive longitudinal study of patients cared for at home by a palliative care team. Place of death was analyzed in relation to complexity, as determined by the HexCom complexity model after the initial home assessment. We used Pearson's chi-square test to analyze the comparison of proportions. RESULTS: Forty-six hundred patients (74.4% oncologic) with a mean age of 76.2 years (SD 13.2) participated. Fifty-three percent had complete or severe functional dependence, 30.8% were already bedridden in the first assessment, and 59.7% died at home. Strengths influenced place of death, specifically exosystem (team) strength (OR: 4.07 [1.92-8.63]), microsystem (both patient 0.51 [0.28-0.94]) and caregiver (OR: 3.90 [1.48-10.25]), and chronosystem, related to prediction of progressive course (OR: 2.22 [1.37-3.60]). CONCLUSIONS: To improve care for end-of-life patients and their families, a systemic view of dying and death that includes both needs and strengths is necessary. In this sense, the systemic framework proposed by Bonfrenbrenner can be useful for clinical practice.

Quantitative assessments of late radiation-induced skin and soft tissue toxicity and correlation with RTOG scales and biological equivalent dose in breast cancer.

PURPOSE: Radiation-induced toxicity (RIT) is usually assessed by inspection and palpation. Due to their subjective and unquantitative nature, objective methods are required. This study aimed to determine whether a quantitative tool is able to assess RIT and establish an underlying BED-response relationship in breast cancer. METHODS: Patients following seven different breast radiation protocols were recruited to this study for RIT assessment with qualitative and quantitative examination. The biologically equivalent dose (BED) was used to directly compare different radiation regimens. RIT was subjectively evaluated by physicians using the Radiation Therapy Oncology Group (RTOG) late toxicity scores. Simultaneously an objective multiprobe device was also used to quantitatively assess late RIT in terms of erythema, hyperpigmentation, elasticity and skin hydration. RESULTS: In 194 patients, in terms of the objective measurements, treated breasts showed higher erythema and hyperpigmentation and lower elasticity and hydration than untreated breasts (p < 0.001, p < 0.001, p < 0.001, p = 0.019, respectively). As the BED increased, Δerythema and Δpigmentation gradually increased as well (p = 0.006 and p = 0.002, respectively). Regarding the clinical assessment, the increase in BED resulted in a higher RTOG toxicity grade (p < 0.001). Quantitative assessments were consistent with RTOG scores. As the RTOG toxicity grade increased, the erythema and pigmentation values increased, and the elasticity index decreased (p < 0.001, p = 0.016, p = 0.005, respectively). CONCLUSIONS: The multiprobe device can be a sensitive and simple tool for research purpose and quantitatively assessing RIT in patients undergoing radiotherapy for breast cancer. Physician-assessed toxicity scores and objective measurements revealed that the BED was positively associated with the severity of RIT.

Drug-related problems in patients admitted for SARS-CoV-2 infection during the COVID-19 pandemic.

Introduction: Drug-related problems (DRP) are events or circumstances in which drug therapy does or could interfere with desired health outcomes. In December 2019, a new coronavirus, SARS-CoV-2, appeared. Little knowledge about this type of infection resulted in the administration of various drugs with limited use in other pathologies. Evidence about DRP in patients with COVID-19 is lacking. Objective: The aim of the present study is to describe identified cases of DRP and those drugs involved in the first wave of patients with COVID-19, and evaluate associated risk factors. Material and methods: Observational, retrospective study performed in a tertiary university hospital between 14th March 2020 and 31 May 2020 (corresponding to the first COVID-19 wave). We recruited patients admitted during the study period. Exclusion criteria included age < 18 years; admission to critically ill units; and care received either in the emergency room, at-home hospitalization or a healthcare center. Results: A total of 817 patients were included. The mean age was 62.5 years (SD 16.4) (range 18-97), and 453 (55.4%) were male. A total of 516 DRP were detected. Among the patients, 271 (33.2%) presented at least one DRP. The mean DRP per patient with an identified case was 1.9. The prevailing DRPs among those observed were: incorrect dosage (over or underdosage) in 145 patients (28.2%); wrong drug combination in 131 (25.5%); prescriptions not in adherence to the then COVID-19 treatment protocol in 73 (14.1%); prescription errors due to the wrong use of the computerized physician order entry in 47 (9.2%); and incorrect dosage due to renal function in 36 (7%). The logistic regression analysis showed that patients who received only prescriptions of antibacterials for systemic use (J01 ATC group) faced a higher likelihood of experiencing a DRP (OR 2.408 (1.071-5.411), p = 0.033). Conclusion: We identified several factors associated with an increased risk of DRPs, similar to those reported in other pre-pandemic studies, including a prolonged length of stay, higher number of prescribed drugs and antimicrobial administration. The relevance of pharmacists and tools like pharmacy warning systems can help prevent, identify and resolve DRP efficiently.

Active humidification in mechanical ventilation is not associated to an increase in respiratory infectious complications in a quasi-experimental pre-post intervention study.

OBJECTIVE: There is controversy regarding the influence of humidification systems upon the incidence of respiratory infections associated to invasive mechanical ventilation (IMV). An evaluation was made of the differences in the incidence of pneumonia and tracheobronchitis associated to mechanical ventilation (VAP and VAT, respectively) with passive and active humidification. DESIGN: A retrospective pre-post quasi-experimental study was carried out. SETTING: A polyvalent ICU with 14 beds. PATIENTS: All patients connected to IMV for >48h during 2014 and 2016 were included. INTERVENTIONS: During 2014, passive humidification with an hygroscopic heat and moisture exchanger (HME) was used, while during 2016 active humidification with a heated humidifier (HH) and an inspiratory heated wire was used. Identical measures for the prevention of VAP were established (Zero Pneumonia Project). MAIN OUTCOME MEASURES: The incidence of VAP and VAT was estimated for 1000 days of IMV in both groups, and statistically significant differences were assessed using Poisson regression analysis. RESULTS: A total of 287 patients were included (116 with HME and 171 with HH). The incidence density of VAP per 1000 days of IMV was 5.68 in the HME group and 5.80 in the HH group (p=ns). The incidence density of VAT was 3.41 and 3.26 cases per 1000 days of VMI with HME and HH respectively (p=ns). The duration of IMV was identified as a risk factor for VAP. CONCLUSIONS: In our population, active humidification in patients ventilated for >48h was not associated to an increase in respiratory infectious complications.

Response to intravenous lidocaine in a patient with SUNCT syndrome.

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) syndrome represents a serious therapeutic and diagnostic challenge, since it is usually refractory to most drugs and lacks biological markers. Response to intravenous lidocaine administration has been reported in some patients while it has failed in others. We report a patient with SUNCT syndrome who showed a clear-cut and consistent response to intravenous lidocaine therapy, which proved superior to placebo in a single-blinded fashion. Intravenous lidocaine should be considered in all patients with SUNCT syndrome. Response to this therapy could represent a diagnostic tool.

Evaluation of the learning curve for laparoscopic pancreatoduodenectomy by CUSUM analyses. Cohort study.

INTRODUCTION: Laparoscopic pancreatoduodenectomy (LPD) remains an extremely demanding surgery. The purpose of this study was to describe the learning curve required for its safe implementation. METHODS: Fifty consecutive patients undergoing LPD were retrospectively reviewed. The learning curve was clustered into 4 groups: A, B and C (initial phase, n = 10 each) and D (consolidation phase, n = 20). Cumulative Sum (CUSUM) analysis was applied to operative time, conversion rate and severe postoperative complications. RESULTS: No significant differences were observed among groups and phases concerning specific and general postoperative complications, oncological outcomes or mortality. The conversion rate significantly reduced from 90% (9) in Group A to 40% (4) in Group C (p < 0.01). Operative time was longer in the consolidation phase (median of 506 vs 437 min, p < 0.01). Conversely, hospital stays were shorter during the consolidation phase (8 vs 15 days, p < 0.01). CUSUM analysis identified 20-25cases as being enough to complete the learning curve if operative time and severe complications are analysed, while 40 cases would be needed for considering the conversion rate. CONCLUSIONS: The learning curve in LPD can be completed after 20-25 procedures. This information will help to design programmes for introducing new surgeons to this technique.

Relation between Epidural Analgesia and severe perineal laceration in childbearing women in Catalonia.

OBJECTIVE: Our objectives were to study the association between epidural analgesia and risk of severe perineal laceration (SPL), and identify additional risk factors for SPL. This multicentre study consisted of an analysis of data from the MidconBirth Phase I Database, on the use of EA and perineal results during childbirth. (World Health Organization, International Clinical Trials Registry Platform, 2016: http://apps.who.int/trialsearch/Trial2.aspx?TrialID=ISRCTN17833269). METHODS: We conducted a prospective study of pregnant women at term between July 2016 and July 2017 in 30 public maternity hospitals in Catalonia, Spain. Inclusion criteria were an uncomplicated singleton pregnancy, in cephalic presentation and vaginal birth. Data was analysed separately for instrumental births and spontaneous vaginal births, as the former is more frequently associated with episiotomy and more perineal lacerations. Risk factors as well as protective factors in each cohort of women (instrumental and spontaneous vaginal birth), were identified. Multivariate logistic regression model was performed to study the association between epidural analgesia and SPL to identify potential confounders. Odds ratios (OR), using 95% confidence intervals (CI) were constructed. FINDINGS: During the study period, 5497 eligible women gave birth, 77.46% of them received epidural analgesia. SPL occurred in 1.63% of births. The univariate analysis showed births with epidural analgesia had significantly higher rates of inductions, augmentation of labour, lithotomy position for birth and episiotomy. However, this association disappeared when the variable "type of vaginal birth" was introduced. In multivariate logistic regression, nulliparity was the major predictor for SPL (OR: 0.17; CI 95%: 0.08-0.34, p: 0.000). KEY CONCLUSIONS: Epidural analgesia was not associated with SPL once confounding factors were included. Other interesting factors associated with SPL were identified. IMPLICATIONS FOR PRACTICE: This paper identifies important practice areas which contribute to SPL and which have the potential to be rectified. It offers evidence on the role that EA plays on pelvic floor injuries and it adds to existing evidence about the disadvantages of using the lithotomy position for birth, especially in relation to SPL. It highlights the need for practice change in Catalonia from what can be considered a medical model of care to one more aligned with the midwifery philosophy of care through the development of clinical guidelines. It also signals the need to provide women with evidence base upon which to make informed choices on the use of EA, specifically in relation to SPL.

Translation and Validation of the Spanish Version of the SARC-F Questionnaire to Assess Sarcopenia in Older People.

OBJECTIVES: The revised European consensus on sarcopenia definition and diagnosis (EWGSOP2) includes the SARC-F questionnaire, the most valid and consistent sarcopenia screening tool, as the mandatory first step. Our aim was the translation, cross-cultural adaptation, and validation of the SARC-F questionnaire as a culturally-responsive Spanish-language version for the European population. STUDY DESIGN: Cross-sectional descriptive study, applying the two-step WHO methodology for translation and cross-cultural adaptation of health questionnaires, and harmonization with the Mexican-Spanish version. European Union Geriatric Medicine Society recommendations for SARC-F validation in European languages were considered. PARTICIPANTS: Outpatient clinics of a university hospital. INCLUSION CRITERIA: stable, ambulatory (including aids), community-dwelling population ≥65 years old. MAIN OUTCOME MEASURES: The self-reported 5-item SARC-F questionnaire was administered; scores ≥4 indicated sarcopenia. Sensitivity, specificity, accuracy-likelihood ratios, predictive values, and kappa statistics were calculated and consecutively compared with European Working Group on Sarcopenia in Older People (EWGSOP) and EWGSOP2 criteria. RESULTS: This Spanish version, administered in an average 70s, has adequate internal consistency (Cronbach alpha=0.779). For the validation study, 90 (43.3%) of 208 potentially eligible subjects (81.4 ± 5.9 years old, 75.6% women) were included. SARC-F identified 51 (56.7%) subjects with sarcopenia and 39 (43.3%) without the disease. Prevalence was 17.8% per EWGSOP and 25.6% per EWGSOP2 (58% accuracy and fair agreement: sensitivity, 78.3%; specificity, 50.8%). CONCLUSIONS: SARC-F is a feasible tool, suitable for bedside assessment in community-dwelling older patients. Wide diffusion of this culturally-responsible SARC-F Spanish version is expected as EWGSOP2 is adopted and sarcopenia assessment is broadly implemented in Spain.

Impact of an antimicrobial stewardship program on urinary tract infections caused by extended-spectrum ß-lactamase-producing Escherichia coli.

OBJECTIVE: To analyze the clinical and economic impact of an antimicrobial stewardship program (ASP) targeting urinary tract infections (UTI) caused by extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli. METHODS: An observational retrospective study that included adults with a diagnosis of UTI caused by ESBL-producing E. coli admitted to a tertiary care hospital in Barcelona, Spain, between January 2014 and December 2015. The impact of the ASP was analyzed in terms of clinical and economic outcomes. RESULTS: A total of 222 patients met the inclusion criteria and an intervention was made by the ASP team in 104 cases (47%). ASP intervention was an independent variable related to clinical cure (p = 0.008). Other variables influencing clinical outcomes were the McCabe Jackson score (p = 0.005) and outpatient status (p < 0.001). The ASP interventions in this study had no economic impact. CONCLUSIONS: Antimicrobial stewardship has a positive clinical impact on UTIs caused by ESBL-producing E. coli. Further prospective studies are needed to assess the economic impact of ASPs on UTI caused by ESBL-producing E. coli.

[Effectiveness of an assessment of computerised medical records in a university hospital]. / Efectividad de la evaluación de historias clínicas informatizadas en un hospital universitario.

OBJECTIVE: The objective of this study was to evaluate a sample of electronic medical records (EMR) that was sufficiently representative of the different areas of care in a university hospital, as well as to verify the effectiveness of an initial intervention through a second evaluation. METHODS: Medical records audits were performed in 2012 and 2013 by a blind peer review of random samples of care episodes, proportional to the activity of each clinical department, and with the same evaluation method being applied to all of them. RESULTS: More than 1,000 episodes of care were reviewed in the 2audits. A significant improvement was found in hospital admissions (P=.000) in all the sections of the EMR analysed (P=.002), and was especially significant for the reason for consultation, for which its completion increased by 8.5% (p<.05), and also in the sections of the current process record (7.1%), physical examination (4.7%), allergies (3.9%), and clinical course (3.6%). The assessment of the discharge report, as a whole, showed an improvement (P=.001). In outpatient follow-up visits, a significant positive improvement was observed in the 4sections evaluated (P<.05), and also overall (P=.000). CONCLUSIONS: According to study conditions, the dissemination of the results was effective in improving the quality of the EMR. The results have made it possible to implement actions to review the work processes in certain departments, and also the partial redesign of the interface on being a reproducible methodology accepted by the organisation.

As the RTOG toxicity grade increased, the erythema and pigmentation values increased, and the elasticity index decreased (p < 0.001, p = 0.016, p = 0.005, respectively).ConclusionsThe multiprobe device can be a sensitive and simple tool for research purpose and quantitatively assessing RIT in patients undergoing radiotherapy for breast cancer. Physician-assessed toxicity scores and objective measurements revealed that the BED was positively associated with the severity of RIT.

La humidificación activa en ventilación mecánica no se asocia con un aumento de complicaciones infecciosas respiratorias en un estudio cuasi-experimental pre-postintervención / Active humidification in mechanical ventilation is not associated to an increase in respiratory infectious complications in a quasi-experimental pre-post intervention study

Objetivo Existen controversias sobre la influencia del sistema de humidificación en la incidencia de infecciones respiratorias asociadas a la ventilación mecánica invasiva (VMI). Nuestro objetivo fue evaluar las diferencias en la incidencia de neumonía y traqueobronquitis asociadas a la ventilación mecánica (NAV y TAV respectivamente) con humidificación pasiva y activa. Diseño Estudio retrospectivo cuasi-experimental de tipo pre-postintervención. Ámbito UCI polivalente de 14 camas. Pacientes Se incluyeron todos los pacientes conectados a la VMI durante>48horas durante los años 2014 y 2016. Intervenciones Durante el año 2014 se empleaba humidificación pasiva con un intercambiador calor-humedad (HME) y, durante 2016, humidificación activa (HH) con calentamiento de la tubuladura inspiratoria. Se establecieron medidas idénticas para la prevención de NAV (proyecto Neumonía Zero). Variables de interés principales Se estimaron tasas de incidencia NAV y TAV por 1.000 días de VMI en ambos grupos y se valoraron diferencias estadísticamente significativas mediante regresión Poisson. Resultados Se incluyeron 287 pacientes (116 con HME y 171 con HH). La densidad de incidencia de NAV por 1.000 días de VMI fue de 5,68 en el grupo de HME y 5,80 en el grupo de HH (p=ns). La densidad de incidencia de TAV fue 3,41 y 3,26 casos por 1.000 días de VMI con HME y HH respectivamente (p=ns). Se identificó como factor de riesgo de NAV la duración de la VMI. Conclusiones En nuestro estudio la humidificación activa en pacientes ventilados durante>48horas no se asoció con un aumento de las complicaciones infecciosas respiratorias. (AU)

Conclusions In our population, active humidification in patients ventilated for>48hours was not associated to an increase in respiratory infectious complications. (AU)

Calidad de vida en niños con trastorno por déficit de atención con o sin hiperactividad (TDAH) / Quality of life in children with attention deficit hyperactivity disorder

Introducción: el trastorno por déficit de atención e hiperactividad (TDAH) es el problema del neurodesarrollo más frecuente en la infancia. La definición de trastorno hace alusión a aquellos problemas que con sus efectos generan malestar en las personas y en su entorno. De origen multifactorial, con base neurobiológica, fuerte predisposición genética e interacción con factores ambientales. Un 75% de niños con TDAH seran adolescentes con TDAH, y de estos, un 50% serán adultos con TDAH. Provoca un gran impacto a nivel cognitivo, emocional y social. El objetivo del estudio consiste en valorar la repercusión del TDAH en el ámbito familiar, escolar y social, desde la óptica de la Atención Primaria, mediante el concepto de calidad de vida relacionada con la salud (CVRS), definida como la autopercepción subjetiva e individual de los pacientes respecto a su salud, así como el grado de bienestar físico, social y psicológico respecto a la enfermedad y al tratamiento. Material y métodos: para valorar la CVRS prospectivamente se aplicó el cuestionario KINDL® a dos grupos de niños de 6 a 16 años, uno recientemente diagnosticado de TDAH, sin haber iniciado tipo alguno de tratamiento, y otro de niños sin TDAH. Resultados: el resultado, tanto de la valoración global de la CVRS, como de sus seis dimensiones, muestra diferencias significativas con una percepción de calidad menor en el grupo de niños con TDAH respecto al grupo control. Conclusión: por tanto, el TDAH compromete seriamente la calidad de vida de los niños que lo padecen (AU)

Introduction: the Attention Deficit Hyperactivity Disorder (ADHD) is the most common neurodevelopmental disorder in childhood. It’s definition points toward those problems which originate discomfort in persons and their environment. ADHD has a multifactorial origin, with a neurobiological basis, strong genetic component and interaction with environmental factors. Nearly 75% of children with ADHD will be adolescents with ADHD, and 50% of them will be adults with ADHD. This disorder causes a great impact at cognitive, emotional and social levels. The objective of this study is to evaluate the impact of ADHD over the family, school and social relationships of affected children under the view of primary care, using the concept of Health Related Quality of Life (HRQoL), defined as the individual and subjective patient’s self-perception related to their own health, as well as the degree of physical, psychological and social welfare in respect to the disease and the treatment. Material and methods: KINDL® was used in the evaluation of HRQoL. It was applied to two groups children aged from 6 to 16 years old. One group included children with a recent diagnosis of ADHD and still not treated with any therapy. The other group consisted in children without ADHD. Results: results showed that the global score of HRQoL as well as the six dimensions which compose this measure have significant differences. The HRQoL is significantly lower in the group of ADHD children when compared with the control group. Conclusion: as a main conclusion, ADHD impairs seriously the quality of life of children who suffer such disorder (AU)

Short-term myocardial ischemia induces cardiac modified C-reactive protein expression and proinflammatory gene (cyclo-oxygenase-2, monocyte chemoattractant protein-1, and tissue factor) upregulation in peripheral blood mononuclear cells.

BACKGROUND: Prompt coronary thrombus resolution, reducing time of ischemia, improves cardiac recovery. The factors triggered by ischemia that contribute to the clinical outcome are not fully known. We hypothesize that unabated inflammation due to cardiac ischemia may be a contributing factor. AIMS: As a proof-of-concept, we evaluated the effect of short-term myocardial ischemia on the local and systemic inflammatory response. METHODS: Pigs underwent either 90-min mid-left anterior descending (LAD) coronary artery balloon occlusion (infarct size 25% +/- 1% left ventricle; 29% heart function deterioration) or a sham-operation procedure. Peri-infarcted and non-ischemic cardiac tissue was obtained for histopathologic, molecular and immunohistochemical analysis of inflammatory markers [interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), modified C-reactive protein (mCRP), and human alveolar macrophage-56 (HAM-56)]. Blood (femoral vein) was withdrawn prior to myocardial infarction (MI) induction (t = 0) and at 30 and 90 min to evaluate: (i) systemic cytokine levels (IL-6, TNF-alpha, CRP); (ii) proinflammatory gene and protein expression in peripheral blood mononuclear cells (PBMCs) of tissue factor (TF), cyclo-oxygenase-2 (Cox-2), monocyte chemoattractant protein-1 (MCP-1), and CRP; and (iii) platelet activation (assessed by perfusion studies and RhoA activation). RESULTS: Short-term ischemia triggered cardiac IL-6 and TNF-alpha expression, recruitment of inflammatory cells, and mCRP expression in infiltrated macrophages (P < 0.05 vs. t = 0 and sham). PBMC mRNA and protein expression of MCP-1, Cox-2 and TF was significantly increased by ischemia, whereas no differences were detected in CRP. Ischemia increased cardiac troponin-I, IL-6 and TNF-alpha systemic levels, and was associated with higher platelet deposition and RhoA activation (P < 0.001 vs. t = 0 and sham). CONCLUSION: Short-term myocardial ischemia, even without atherosclerosis, induces an inflammatory phenotype by inducing local recruitment of macrophages and systemic activation of mononuclear cells, and renders platelets more susceptible to activation.
