Abstract
Objective The purpose of this study was to determine whether the use of a humanoid robot (Estrabot) could reduce preoperative anxiety levels in children. Methods An experimental study was conducted at Azienda Ospedaliero Universitaria delle Marche Hospital, involving the Pediatric Surgery ward and the Operating Room (OR). Patients aged between 2 and 14 years who underwent minor surgery were included. The Instruments used were the Children's Emotional Manifestation Scale to evaluate anxiety levels, and Estrabot, a humanoid robot that interacts with people. Medical records between April and May 2023 were analyzed and the data was anonymous. The level of anxiety is extrapolated in Pediatric Surgery during the administration of oral pre-medication, and in the Operating Room, during the induction of anesthesia. Patients were divided into an intervention group treated with Estrabot, and a control group without a robot. Results The population consists of 60 patients (86.7% male) with a median (IQR) age of 6 (4-8) years. The median (IQR) anxiety score during premedication was 7 (5-11), while the median (IQR) anxiety score during anesthesia was 6 (5-10). A significantly lower level of anxiety was reported in the Estrabot group. Patients in the Estrabot group had significantly lower anxiety levels in different age groups. Conclusion A humanoid robot can reduce preoperative anxiety levels in children during premedication and the induction of anesthesia.

Abstract
BACKGROUND Pediatric patients affected by oncologic disease have a significant risk of clinical deterioration that requires admission to the intensive care unit. This study reported the results of a national survey describing the characteristics of Italian onco-hematological units (OHUs) and pediatric intensive care units (PICUs) that admit pediatric patients, focusing on the high-complexity treatments available before PICU admission, and evaluating the approach to the end-of-life (EOL) when cared in a PICU setting. METHODS A web-based electronic survey has been performed in April 2021, involving all Italian PICUs admitting pediatric patients with cancer participating in the study. RESULTS Eighteen PICUs participated, with a median number of admissions per year of 350 (IQR 248-495). Availability of Extracorporeal Membrane Oxygenation therapy and the presence of intermediate care unit are the only statistically different characteristics between large or small PICUs. Different high-level treatments and protocols are performed in OHUs, non depending on the volume of PICU. Palliative sedation is mainly performed in the OHUs (78%), however, in 72% it is also performed in the PICU. In most centers protocols that address EOL comfort care and treatment algorithms are missing, non depending on PICU or OHU volume. CONCLUSIONS A non-homogeneous availability of high-level treatments and in OHUs is described. Moreover, protocols addressing EOL comfort care and treatment algorithms in palliative care are lacking in many centers.

Abstract
BACKGROUND Emergence Delirium (ED) is a combination of disturbance of perception and psychomotor agitation that is common in pediatric patients after general anesthesia, especially at preschool age. Since the effect of ED on the length of stay has been studied in adults but infrequently in children, the aim of this study was to investigate the relationship between ED and length of stay in this population. METHODS A single center, retrospective, observational study was carried out in children who underwent tonsillectomy or adenotonsillectomy. The Pediatric Anesthesia Emergence Delirium (PAED) scale was used to assess ED. In addition to the time to hospital discharge (time frame 24 hours), drugs used, comorbidities, early postoperative complications, and pain were investigated if potentially associated with the complication. RESULTS Four hundred sixteen children aged from 1.5 to 10 years (183 female, 233 male) were included. ED occurred in 25.5% of patients (n = 106). Patients were divided into the ED group and the No-ED group. The discharge time was similar in both groups. No significant differences were observed in the frequency of postoperative complications. The use of fentanyl or dexmedetomidine did not affect ED occurrence. The frequency of pain was greater in the ED group, both in the recovery room and in the ward (p = 0.01). CONCLUSIONS The occurrence of ED in children after tonsillectomy/adenotonsillectomy did not extend the length of stay.

Abstract
Background The appropriate timing of surgery and perioperative management of patients with previous SARS-CoV-2 infection are open issues. The purpose of this document is to support the clinical decision-making process regarding the patient with previous Sars-CoV-2 infection to undergo elective surgery. The recipients of this document are physicians, nurses, healthcare personnel, and other professionals involved in the patient’s surgical process. Methods The Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care (SIAARTI) selected 11 experts to reach a consensus on key aspects of this theme in adult and pediatric population. The methods of this process document were in accordance to the principles of rapid review of the scientific literature and modified Delphi method. The experts produced statements and supporting reasons in the form of an informative text. The overall list of statements was subjected to a vote in order to express the degree of consent. Results Patients should not undergo elective surgery within 7 weeks of infection unless there is the risk of a negative evolution of the disease. To mitigate the risk of postsurgical mortality, a multidisciplinary approach seemed useful in addition to the use of validated algorithms to estimate the risk of perioperative morbidity and mortality; the risk related to SARS-CoV-2 infection should be added. The risk of potential nosocomial contagion from a positive patients should also be considered when deciding to proceed with surgery. Most of the evidence came from previous SARS-CoV-2 variants, so the evidence should be considered indirect. Conclusion A balanced preoperative multidisciplinary risk–benefit evaluation is needed in patients with previous infection by SARS-CoV-2 for elective surgery.

Abstract
BACKGROUND Pediatric robotic-assisted surgeries have increased in recent years; however, guidance documents are still lacking. This study aimed to develop evidence-based recommendations, or best practice statements when evidence is lacking or inadequate, to assist surgical teams internationally. METHODS A joint consensus taskforce of anesthesiologists and surgeons from the Italian Society of Pediatric and Neonatal Anesthesia and Intensive Care (SARNePI) and the Italian Society of Pediatric Surgery (SICP) have identified critical areas and reviewed the available evidence. The taskforce comprised 21 experts representing the fields of anesthesia (n = 11) and surgery (n = 10) from clinical centers performing pediatric robotic surgery in the Italian cities of Ancona, Bologna, Milan, Naples, Padua, Pavia, Perugia, Rome, Siena, and Verona. Between December 2020 and September 2021, three meetings, two Delphi rounds, and a final consensus conference took place. RESULTS During the first planning meeting, the panel agreed on the specific objectives, the definitions to apply, and precise methodology. The project was structured into three subtopics: (i) preoperative patient assessment and preparation; (ii) intraoperative management (surgical and anesthesiologic); and (iii) postoperative procedures. Within these phases, the panel agreed to address a total of 18 relevant areas, which spanned preoperative patient assessment and patient selection, anesthesiology, critical care medicine, respiratory care, prevention of postoperative nausea and vomiting, and pain management. CONCLUSION Collaboration among surgeons and anesthesiologists will be increasingly important for achieving safe and effective RAS procedures. These recommendations will provide a review for those who already have relevant experience and should be particularly useful for those starting a new program.

Abstract
Background. It was previously reported that health care professionals working in the fields of anesthesiology and emergency are at higher risk of burnout. However, the correlations between burnout, alexithymia, and other psychological symptoms are poorly investigated. Furthermore, there is a lack of evidence on which risk factors, specific to the work of anesthetists and intensivists, can increase the risk of burnout, and which are useful for developing remedial health policies. Methods. This cross-sectional study was conducted in 2020 on a sample of 300 professionals recruited from AAROI-EMAC subscribers in Italy. Data collection instruments were a questionnaire on demographic, education, job characteristics and well-being, the Maslach Burnout Inventory Tool, the Toronto Alexithymia Scale, the Symptom Checklist-90-R, and the Rosenberg Self-Esteem Scale administered during refresher courses in anesthesiology. Correlations between burnout and physical and psychological symptoms were searched. Results. With respect to burnout, 29% of individuals scored at high risk on emotional exhaustion, followed by 36% at moderate–high risk. Depersonalization high and moderate–high risk were scored by 18.7% and 34.3% of individuals, respectively. Burnout personal accomplishment was scored by 34.7% of respondents. The highest mean scores of burnout dimensions were related to dissatisfaction with one’s career, conflicting relationships with surgeons, and, finally, difficulty in explaining one’s work to patients. Conclusions. Burnout rates in Italian anesthesiologists and intensivists have been worrying since before the COVID-19 pandemic. Anesthesiologists with higher levels of alexithymia are more at risk for burnout. It is therefore necessary to take urgent health policy measures.

Abstract
Although ketamine is primarily used for induction and maintenance of general anesthesia, it also presents sedative, amnestic, anesthetics, analgesic, antihyperalgesia, neuroprotective, anti-inflammatory, immunomodulant, and antidepressant effects. Its unique pharmacodynamics and pharmacokinetic properties allow the use of ketamine in various clinical settings including sedation, ambulatory anesthesia, and intensive care practices. It has also adopted to manage acute and chronic pain management. Clinically, ketamine produces dissociative sedation, analgesia, and amnesia while maintaining laryngeal reflexes, with respiratory and cardiovascular stability. Notably, it does not cause respiratory depression, maintaining both the hypercapnic reflex and the residual functional capacity with a moderate bronchodilation effect. In the pediatric population, ketamine can be administered through practically all routes, making it an advantageous drug for the sedation required setting such as placement of difficult vascular access and in uncooperative and oppositional children. Consequently, ketamine is indicated in prehospital induction of anesthesia, induction of anesthesia in potentially hemodynamic unstable patients, and in patients at risk of bronchospasm. Even more, ketamine does not increase intracranial pressure, and it can be safely used also in patients with traumatic brain injuries. This article is aimed to provide a brief and practical summary of the role of ketamine in the pediatric field.

Abstract
A surgical site infection (SSI) is an infection that occurs in the incision created by an invasive surgical procedure. Although most infections are treatable with antibiotics, SSIs remain a significant cause of morbidity and mortality after surgery and have a significant economic impact on health systems. Preventive measures are essential to decrease the incidence of SSIs and antibiotic abuse, but data in the literature regarding risk factors for SSIs in the pediatric age group are scarce, and current guidelines for the prevention of the risk of developing SSIs are mainly focused on the adult population. This document describes the current knowledge on risk factors for SSIs in neonates and children undergoing surgery and has the purpose of providing guidance to health care professionals for the prevention of SSIs in this population. Our aim is to consider the possible non-pharmacological measures that can be adopted to prevent SSIs. To our knowledge, this is the first study to provide recommendations based on a careful review of the available scientific evidence for the non-pharmacological prevention of SSIs in neonates and children. The specific scenarios developed are intended to guide the healthcare professional in practice to ensure standardized management of the neonatal and pediatric patients, decrease the incidence of SSIs and reduce antibiotic abuse.

Abstract
PURPOSE To analyze the mechanisms involved in the fetal heart rate (FHR) abnormalities after the epidural analgesia in labor. METHODS A prospective unblinded single-center observational study on 55 term singleton pregnant women with spontaneous labor. All women recruited underwent serial bedside measurements of the main hemodynamic parameters using a non-invasive ultrasound system (USCOM-1A). Total vascular resistances (TVR), heart rate (HR), stroke volume (SV), cardiac output (CO) and arterial blood pressure were measured before epidural administration (T0), after 5 min 5 (T1) from epidural bolus and at the end of the first stage of labor (T2). FHR was continuously recorded through computerized cardiotocography before and after the procedure. RESULTS The starting CO was significantly higher in a subgroup of women with low TVR than in women with high-TVR group. After the bolus of epidural analgesia in the low-TVR group there was a significant reduction in CO and then increased again at the end of the first stage, in the high-TVR group the CO increased insignificantly after the anesthesia bolus, while it increased significantly in the remaining part of the first stage of labor. On the other hand, CO was inversely correlated with the number of decelerations detected on cCTG in the 1 hour after the epidural bolus while the short-term variation was significantly lower in the group with high-TVR. CONCLUSION Maternal hemodynamic status at the onset of labor can make a difference in fetal response to the administration of epidural analgesia.

Abstract
For many years, it was clearly shown that surgical procedures might be associated with surgical site infection (SSI). Many scientific institutions prepared guidelines to use in surgery to reduce abuse and misuse of antibiotics. However, in the general guidelines for surgical antibiotic prophylaxis, plastic surgical procedures are not addressed or are only marginally discussed, and children were almost systematically excluded. The main aim of this Consensus document is to provide clinicians with recommendations on antimicrobial prophylaxis for pediatric patients undergoing plastic surgery. The following scenarios were considered: clean plastic surgery in elective procedures with an exclusive skin and subcutis involvement; clean-contaminated/contaminated plastic surgery in elective procedures with an exclusive skin and subcutis involvement; elective plastic surgery with use of local flaps; elective plastic surgery with the use of grafts; prolonged elective plastic surgery; acute burns; clean contused lacerated wounds without bone exposure; high-risk contused lacerated wounds or with bone exposure; contused lacerated wound involving the oral mucosa; plastic surgery following human bite; plastic surgery following animal bite; plastic surgery with tissue expander insertion. Our Consensus document shows that antimicrobial perioperative prophylaxis in pediatric patients undergoing plastic surgery is recommended in selected cases. While waiting the results of further pediatric studies, the application of uniform and shared protocols in these procedures will improve surgical practice, with a reduction in SSIs and consequent rationalization of resources and costs, as well as limiting the phenomenon of antimicrobial resistance.

Abstract
Surgical site infections (SSIs) represent a potential complication in any type of surgery and can occur up to one year after the procedure in the case of implant placement. In the field of orthopedic and hand surgery, the rate of SSIs is a relevant issue, considering the need for the placement of synthesis devices and the type of some interventions (e.g., exposed fractures). This work aims to provide guidance on the management of peri-operative antibiotic prophylaxis for the pediatric and neonatal population undergoing orthopedic and hand surgery in order to standardize the management of patients and to reduce, on the one hand, the risk of SSI and, on the other, the development of antimicrobial resistance. The following scenarios were considered: (1) bloodless fracture reduction; (2) reduction of unexposed fracture and grade I and II exposed fracture; (3) reduction of grade III exposed fracture or traumatic amputation; (4) cruel fracture reduction with percutaneous synthesis; (5) non-traumatic amputation; (6) emergency intact skin trauma surgery and elective surgery without synthetic media placement; (7) elective orthopedic surgery with prosthetic and/or synthetic media placement and spinal surgery; (8) clean elective hand surgery with and without bone involvement, without use of synthetic means; (9) surgery of the hand on an elective basis with bone involvement and/or with use of synthetic means. This manuscript has been made possible by the multidisciplinary contribution of experts belonging to the most important Italian scientific societies and represents, in our opinion, the most complete and up-to-date collection of recommendations regarding the behavior to be adopted in the peri-operative setting in neonatal and pediatric orthopedic and hand surgery. The specific scenarios developed are aimed at guiding the healthcare professional in practice to ensure the better and standardized management of neonatal and pediatric patients, together with an easy consultation.

Abstract
OBJECTIVES Fire in the operating theater is a potential source of important morbidity for the patient. Laser surgery of the head and neck district presents a particularly high risk of fire due to the presence of all three elements of the 'fire triad,' necessary to cause combustive or explosive events: an oxidiser, a fuel, and a heat source. The aim of the present study is to emphasise the need of new prevention tools and greater adherence to the recommendations available in the literature. METHODS The sudden occurrence of combustion within the airway of an infant undergoing laryngeal laser surgery was presented along with his management. RESULTS An infant underwent CO2 laser surgery for the treatment of the laryngeal stenosis. Unfortunately, the endoscopic procedure was complicated by a fire of the tracheal tube. The tube was immediately removed, the saline was flushed down the trachea and the ventilation was maintained through a face mask. Subsequently, a fiberoscopy was performed and showed a vocal cord burn. CONCLUSIONS Since operating room fires are still an underreported occurrence, we believe that this present work might raise awareness about this potential complication and give useful suggestions for the management of airway fires in paediatric anaesthesia.

Abstract
BACKGROUND Intraoperative dexmedetomidine can be useful for its sedative and analgesic sparing effects, and for the prevention of emergence delirium. Conversely, it can cause hypotension and bradycardia. The aim of this study was to assess the safety and efficacy of dexmedetomidine in pediatric anesthesia. METHODS This is a retrospective cohort study in children who received intravenous dexmedetomidine (Dex group) or opioids (No-Dex group) during general anesthesia for tonsillectomy, between November 2014 and November 2016. From the medical records, data on the intraoperative phase (hemodynamic adverse events, respiratory failure at the emergence, awakening and extubation times, emergence delirium), recovery room (pain, hemodynamic parameters, and desaturation), and ward stay (pain, and nausea and vomiting) were investigated. Time of hospital discharge was calculated. RESULTS Three hundred twenty-eight (Dex group 183; No-Dex group 145) children ranging from 1.5 to 10 years were included. The percentage of intraoperative hypotension was significantly higher in the Dex group (p=0.01). The extubation times were significantly higher in No-Dex group (p=0.0001), although the awakening times were significantly longer with dexmedetomidine (p= 0.0001). Desaturation episodes were higher in the Dex group (p=0.0001). The incidence of emergence delirium was similar in the two groups, but of greater intensity in the No-Dex group. While in the immediate postoperative period there was no difference in pain, after 24 hours, the incidence of pain and vomiting was significantly higher (p=0.003; p=0.0001) in the No-Dex group. CONCLUSIONS Although several outcome parameters showed important advantages of dexmedetomidine over opioid-based regimens in terms of safety and efficacy, issues such as the increased intraoperative hypotension, indicated that it is not possible to draw any definitive conclusions.

Abstract
INTRODUCTION Ibuprofen is a drug widely used in children who underwent elective tonsillectomy or adenotonsillectomy because compared to the other Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) it is considered a safe drug with a low risk of postoperative bleeding. AREAS COVERED We conducted a systematic review with meta-analysis of randomized clinical trials (RCTs) comparing ibuprofen vs. placebo or not-NSAIDs drugs in children aged up to 17 years of age, who underwent elective tonsillectomy or adenotonsillectomy. We searched in MEDLINE, EMBASE and Cochrane from 1990 through 30 April 2019. We searched www.clinicaltrials.gov for relevant ongoing studies. Our primary outcome was postoperative bleeding requiring surgical intervention. Secondary outcomes were postoperative bleeding not requiring further surgical intervention, the need for blood transfusion, nausea, vomiting, prolonged hospital stay, postoperative pain, and adverse events related to ibuprofen administration. The database search yielded 1227 patients from 7 studies. EXPERT OPINION Given the imprecision of our estimates, the quality of evidence very low/moderate and the few RCTs identified, the results of this analysis were consistent with either a benefit or a detrimental effect of the administration of ibuprofen and do not provide a definitive answer to the review question. Further studies are needed on this important topic.

Abstract
The health emergency linked to the Sars-Cov-2 infection represented an absolutely new problem for all health professionals. In particular, the information regarding the spread of the virus in the pediatric field and its manifestations are still incomplete. In this paper we present a case of neonatal infection which, as far as we know, represents one of the few published cases and which occurred in a patient who came to our attention for acute abdomen from intestinal perforation. The perforation was caused by Meckel's diverticulum, an event considered infrequent in the first year of life and almost exceptional in the neonatal period. This case required particular management, putting pediatric surgeons in front of new and difficult to solve problems. New onset clinical events, such as this one described, represent an opportunity for sharing useful data for the creation of universal protocols for the management of patients with problems that are becoming common and of which little is known.

Global cardiovascular risk scores frequently underestimate risk in persons with underlying asymptomatic cardiac lesions who eventually experience cardiovascular events. The Get-With-The-Guidelines Initiative analysis revealed that over 70% of patients with a first cardiac event were well within guideline targets for lipid values. Most artery flow-disrupting events occur at locations with less than 50% lumen narrowing. From clinical studies published in the late 1990s using IVUS (in-the-artery-ultrasound) to visualize disease status, the typical heart attack occurs at locations with about 20% stenosis (narrowing), prior to sudden lumen closure and resulting ACS. This sudden lumen closure is caused by rupture of an unstable cardiac lesion causing a blood clot and occlusion in up to 75% of heart attacks. The role of multi-biomarker algorithms to identify vulnerable patients with these lesions at risk of short-term ACS events is of great interest.
Methods
We studied 725 adults (≥18 yrs) from Cardiology practices who received a 5-year modified Framingham Risk Score (mFRS), and a coronary artery disease predictive algorithm (CADPA) multi-biomarker score. CADPA incorporates 9 biomarkers (CTACK, Eotaxin, Fas Ligand, HGF, IL-16, MCP-3, sFas, HDL, and HbA1c) with age, sex, diabetes, and family history of myocardial infarction, previously shown to more accurately reclassify risk of cardiovascular events (cNRI=43%). Patients were classified into low (<3.5%), intermediate (3.5% - <7.5%), and high (≥7.5%) 5-year risk categories with both mFRS and CADPA. Patients low or intermediate risk by mFRS, but reclassified high by CADPA are reported and compared.
Results
Persons at low, intermediate, and high global risk categories were successively more likely to demonstrate high-risk scores with CADPA (Figure). However, 349 (65%) in the low mFRS risk group were reclassified into higher CADPA risk groups and 104 (70%) intermediate risk patients were reclassified into the high-risk group (p<0.0001 for CADPA vs. mFRS). Analysis demonstrated that 89% (309) of the low or intermediate mFRS [125 females (99%); 184 males (83%); p<0.0001] and, 86 below 65 years (93%) and 223 above 65 years (88%); p=0.26)] were classified as high-risk by CADPA, indicating that many persons who may be at high risk are not identified as such by global risk assessment.
CADPA Risk Reclassification
Conclusions
We conclude that this novel multi-biomarker panel (CADPA) identifies many persons at increased risk of cardiac events due to asymptomatic cardiac lesions missed by traditional global risk methods. Further investigation of the value of such a test for prediction of near-term CVD events is required.

Abstract
Objectives: The aim of our study is to report a case of a child with subglottic thymus that was suspected during diagnostic work-up for severe airway obstruction, excised surgically and confirmed with final histopathological examination. Moreover, we performed a narrative literature review to outline clinical and diagnostic features of this rare condition and to report suggestions for the management of subglottic masses. Methods: We report the case of a 7-month-old boy who was admitted to our Pediatric Airway Team Unit due to a history of worsening biphasic stridor and recurrent episodes of upper airway obstruction. The successful diagnostic work-up and a narrative literature of analogous cases of subglottic thymus were reported. Results: Ectopic thymus is a very rare condition in which thymic tissue is found outside the normal pathway of its embryonic migration. It usually presents as a cystic or, more rarely, solid mass, showing an indolent course toward spontaneous involution. In some cases, however, it becomes symptomatic exerting compression on surrounding vital structures. Due to its rarity, the initial diagnosis is normally mistaken with inflammatory diseases or malignancies and the definitive diagnosis is only achieved after histological examination of the excised specimen. To our knowledge, only four other cases of subglottic ectopic thymic tissue have been reported in the English literature so far and the diagnosis has never been suspected preoperatively. Conclusion: It is mandatory to consider ectopic thymic tissue in the differential diagnosis in children presenting with airways obstruction in order to prevent unnecessary, extensive, and exploratory surgery.

Abstract
OBJECTIVES/HYPOTHESIS Incidence of surgical site infection (SSI) after laryngotracheal (LT) surgery is relatively high, especially in children. STUDY DESIGN Retrospective and prospective cohort study. METHODS Clinical records of children who underwent open LT surgery at the Istituto Giannina Gaslini Children's Hospital from January 2008 to August 2017 were reviewed for development of SSI. Standard antibiotic prophylaxis was administered until February 2015. In March 2015, an antibiotic treatment tailored on pathogens isolated from surveillance cultures and prolonged until extubation was introduced. Incidence and risk factors for SSI before and after the new protocol implementation were analyzed by means of univariate and multivariable analyses. RESULTS A total of 57 procedures were analyzed. SSI incidence was 36% in patients receiving standard prophylaxis and 4% in those treated with the new strategy (P = .004), with an absolute benefit increase of 32% (95% confidence interval: 11%-52%), in absence of any difference in clinical conditions between the two groups. CONCLUSIONS The new management protocol had a highly favorable impact on the development of an SSI. LEVEL OF EVIDENCE 2b Laryngoscope, 129:2634-2639, 2019.

Abstract
During general anesthesia, while muscle relaxants, latex and antibiotics are normally considered as very common causes of anaphylactic reactions, there are no documented cases of anaphylaxis due to inhalational agents. We report the case of a 6-year-old child scheduled for adenotonsillectomy who had an anaphylactic shock reaction due to Sevoflurane. Several allergic tests were performed to detect the trigger. Drugs used during operation were tested on both patient and three matched controls. While controls were negative, the patient displayed a positive reaction to Sevoflurane. To our knowledge, this is the first published report describing an allergic reaction caused by a volatile anesthetic.

Abstract
BACKGROUND Interleukin-8 (IL-8), a CXC chemokine that induces the migration and proliferation of endothelial cells and smooth muscle cells, is a potent angiogenic factor that may play a role in atherosclerosis. Previously, IL-8 has been reported in atherosclerotic lesions and circulating macrophages from patients with atherosclerosis. Therefore, we sought to determine whether IL-8 plays a role in mediating angiogenic activity in atherosclerosis. METHODS AND RESULTS Homogenates from 16 patients undergoing directional coronary atherectomy (DCA) and control samples from the internal mammary artery (IMA) of 7 patients undergoing bypass graft surgery were assessed for IL-8 content by specific ELISA, immunohistochemistry, and in situ hybridization for IL-8 mRNA. The contribution of IL-8 to net angiogenic activity was assessed using the rat cornea micropocket assay and cultured cells. IL-8 expression was significantly elevated in DCA samples compared with IMA samples (1.71+/-0.6 versus 0.05+/-0.03 ng/mg of total protein; P<0.01). Positive immunolocalization of IL-8 was found exclusively in DCA tissue sections, and it correlated with the presence of factor VIII-related antigen. In situ reverse transcriptase polymerase chain reaction revealed the expression of IL-8 mRNA in DCA tissue. Corneal neovascular response, defined by ingrowth of capillary sprouts toward the implant, was markedly positive with DCA pellets, but no constitutive vessel ingrowth was seen with IMA specimens. Neutralizing IL-8 attenuated both the in vivo corneal neovascular response and the in vitro proliferation of cultured cells. CONCLUSIONS The results suggest that, in human coronary atherosclerosis, IL-8 is an important mediator of angiogenesis and may contribute to plaque formation via its angiogenic properties.

Abstract
According to CD28 molecule expression, CD8+ T cells can be classed as CD28bright, CD28dim, and CD28-. The CD28dim T cells were found to derive from mitogenic stimulated CD28-T cells but also from CD28bright T cells through a mechanism of CD28 down-modulation. Moreover, after prolonged in vitro interleukin-2 stimulation, clonal CD28bright, cells showed a CD28dim expression before further evolution to a stable CD28-phenotype. This loss was concomitant with the disappearance of CD28 mRNA. A study of the cytokine production pattern revealed that CD28dim and CD28- T cell clones produced similar levels of type 1 and type 2 cytokines, which differed from those produced by the CD28bright T cell clones. A high percentage of CD28dim and CD28- cells, with similarities in their cytokine production pattern, were found in the blood samples of HIV-infected patients, as compared to healthy donors. The CD28 down-modulation may account for the increased number of CD8+CD28- T cells in HIV-infected patients.

Abstract
This report presents our research on the conditions necessary to substain optimal in vitro prosthetic endothelialization using human endothelium cultures. Human vein endothelial cells were seeded at a concentration of 3 x 10(5)/cm2 in a gelatinized Dacron patch graft coated with a commercial collagen film, using a solution of fibrin glue. Endothelium adhesion, proliferation, and survival were measured by [3H]thymidine incorporation, after 7 days of incubation. Finally, the morphology of prosthetic endothelialization was analyzed by scanning electron microscopy. We observed that the Dacron patch grafts coated with collagen film were able to promote endothelialization better than the prostheses coated with highly concentrated collagen solution or gelatin. We therefore concluded that the collagen film that supports endothelial cell adhesion and proliferation uniformly covers the entire synthetic endoluminal surface of the Dacron graft, thus preventing endothelial cell alterations induced by direct contact with the synthetic prosthetic surface.

Abstract
OBJECTIVE To determine whether heart failure in rats is associated with altered expression of the skeletal muscle sarcoplasmic reticulum Ca2+-ATPase (SERCA). METHODS SERCA protein and mRNA were examined in the soleus muscles of eight female rats with heart failure induced by coronary artery ligation, six weeks after the procedure (mean (SEM) left ventricular end diastolic pressure 20.4 (2.2) mm Hg) and in six sham operated controls by western and northern analyses, respectively. RESULTS SERCA-2a isoform protein was reduced by 16% (112 000 (4000) v 134 000 (2000) arbitrary units, p < 0.001), and SERCA-2a messenger RNA was reduced by 59% (0.24 (0. 06) v 0.58 (0.02) arbitrary units, p < 0.001). Although rats with heart failure had smaller muscles (0.54 mg/g v 0.66 mg/g body weight), no difference in locomotor activity was observed. CONCLUSIONS These results may explain the previously documented abnormalities in calcium handling in skeletal muscle from animals with the same model of congestive heart failure, and could be responsible for the accelerated muscle fatigue characteristic of patients with heart failure.

Abstract
Congestive heart failure is often associated with skeletal muscle abnormalities that contribute to early fatigue and acidosis. Up to the present time, however, the mechanisms responsible for these changes are unclear. Myocardial infarctions were produced by coronary ligation in adult Sprague-Dawley rats. At 20 weeks, 10 control rats, and 15 animals with heart failure [defined by elevated LVEDP (26.1 +/- 3.1 v 2.5 +/- 0.5 mmHg) and RV hypertrophy (300 +/- 21 g v 158 +/- 9 mg)] underwent in vivo measurements of total body, and soleus total protein and myosin heavy chain (MHC) synthesis by [3H]leucine constant infusion. Soleus muscle was also analysed for protein content, and MHC isoenzyme content by SDS-PAGE. Northern blotting also was used to determine levels of the mRNA's encoding type I, IIa, IIb, and IIx MHC, alpha-skeletal actin, COX III, SDH and GAPDH. Soleus muscles in heart failure rats were smaller than controls (112 +/- 6 v 126 +/- 5 mg) and the degree of atrophy was significant when corrected for body mass (0.38 +/- 0.02 v 0.46 +/- 0.02 mg/g. P = 0.007). Although there was no significant difference in plasma leucine flux (an index of whole-body protein synthesis), soleus muscle total and MHC synthesis was reduced in heart failure animals. Whereas the Type I MHC isoenzyme (beta MHC) was the only MHC detected in the soleus of control animals, type II MHC isoenzyme comprised 11.8 +/- 3.1% of the MHC in the heart failure group. Furthermore, steady-state mRNA levels encoding beta MHC were significantly depressed in the heart failure rats, where those encoding Types IIb and IIx MHC were increased. Steady-state mRNA levels of alpha-skeletal actin, cytochrome C oxidase (COX III) and succinate dehydrogenase (SDH) were also significantly depressed. This animal model of chronic heart failure is associated with quantitative and qualitative alterations in skeletal muscle gene expression that are similar to those reported in skeletal muscle of patients with chronic heart failure. The altered phenotype and impaired metabolic capacity may contribute to exercise intolerance in CHF.

Abstract
In patients with congestive heart failure, skeletal muscle is characterized by a smaller proportion of slow-twitch oxidative fibers and reduced oxidative enzyme activity. However, whether these changes result from disuse or occur as a direct consequence of heart failure is unresolved. To address this issue, 18 rats with heart failure 8 weeks after left coronary artery ligation and 13 sham-operated control rats underwent quantification of locomotor activity by a photocell activation technique, measurements of hemodynamics and infarct size, histochemical and morphological analyses of the soleus and plantaris muscles, and Northern analyses of muscle contractile protein and oxidative enzyme mRNA expression. Although the rats with heart failure had elevated left ventricular end-diastolic pressures (24.1 +/- 2.6 mm Hg) and a mean infarct size of 35.1 +/- 4.1%, activity levels were similar to those found in the sham-operated rats (3849 +/- 304 versus 3526 +/- 130 counts per hour). With heart failure, there was a significant reduction of type I fibers in the soleus muscle and type IIa fibers in the plantaris muscle, with corresponding increases in intermediate staining of type IIab fibers in both muscles. This was associated with a 17% decrease in citrate synthase activity in both the soleus and plantaris muscles (26.2 +/- 1.6 versus 30.7 +/- 3.4 and 29.1 +/- 2.4 versus 35.7 +/- 3.4 mumol/L per minute per gram, respectively [P < .05]). In the soleus muscle, mRNA for both beta-myosin heavy chains and cytochrome C oxidase III (normalized to 18S RNA) was reduced (0.27 +/- 0.02 versus 0.65 +/- 0.02 and 0.23 +/- 0.04 versus 0.64 +/- 0.02 U), whereas the messages for IIx and IIb myosin heavy chains were increased. A similar decrease in messages for cytochrome oxidase and the primary myosin isoform was observed in the plantaris muscle. Both soleus beta-myosin heavy chain and cytochrome C oxidase expression show significant inverse relationships to left ventricular end-diastolic pressure and infarct size. In contrast, there was no relationship between either beta-myosin heavy chain or cytochrome C oxidase expression and locomotor activity. These results indicate that in rats heart failure produces changes in skeletal muscle gene expression at the pretranslational level that cannot be explained by inactivity.

Abstract
OBJECTIVES The present study was undertaken to further characterize changes in skeletal muscle morphology and histochemistry in congestive heart failure and to determine the relation of these changes to abnormalities of systemic and local muscle exercise capacity. BACKGROUND Abnormalities of skeletal muscle appear to play a role in the limitation of exercise capacity in congestive heart failure, but information on the changes in muscle morphology and biochemistry and their relation to alterations in muscle function is limited. METHODS Eighteen men with predominantly mild to moderate congestive heart failure (mean +/- SEM New York Heart Association functional class 2.6 +/- 0.2, ejection fraction 24 +/- 2%) and eight age- and gender-matched sedentary control subjects underwent measurements of peak systemic oxygen consumption (VO2) during cycle ergometry, resistance to fatigue of the quadriceps femoris muscle group and biopsy of the vastus lateralis muscle. RESULTS Peak VO2 and resistance to fatigue were lower in the patients with heart failure than in control subjects (15.7 +/- 1.2 vs. 25.1 +/- 1.5 ml/min-kg and 63 +/- 2% vs. 85 +/- 3%, respectively, both p < 0.001). Patients had a lower proportion of slow twitch, type I fibers than did control subjects (36 +/- 3% vs. 46 +/- 5%, p = 0.048) and a higher proportion of fast twitch, type IIab fibers (18 +/- 3% vs. 7 +/- 2%, p = 0.004). Fiber cross-sectional area was smaller, and single-fiber succinate dehydrogenase activity, a mitochondrial oxidative marker, was lower in patients (both p < or = 0.034). Likewise, the ratio of average fast twitch to slow twitch fiber cross-sectional area was lower in patients (0.780 +/- 0.06 vs. 1.05 +/- 0.08, p = 0.019). Peak VO2 was strongly related to integrated succinate dehydrogenase activity in patients (r = 0.896, p = 0.001). Peak VO2, resistance to fatigue and strength also correlated significantly with several measures of fiber size, especially of fast twitch fibers, in patients. None of the skeletal muscle characteristics examined correlated with exercise capacity in control subjects. CONCLUSIONS These results indicate that congestive heart failure is associated with changes in the characteristics of skeletal muscle and local as well as systemic exercise performance. There are fewer slow twitch fibers, smaller fast twitch fibers and lower succinate dehydrogenase activity. The latter finding suggests that mitochondrial content of muscle is reduced in heart failure and that impaired aerobic-oxidative capacity may play a role in the limitation of systemic exercise capacity.
