Abstract
PURPOSE The early regression index (ERI) predicts treatment response in rectal cancer patients. Aim of current study was to prospectively assess tumor response to neoadjuvant chemo-radiotherapy (nCRT) of locally advanced esophageal cancer using ERI, based on MRI. MATERIAL AND METHODS From January 2020 to May 2023, 30 patients with esophageal cancer were enrolled in a prospective study (ESCAPE). PET-MRI was performed: i) before nCRT (tpre); ii) at mid-radiotherapy, tmid; iii) after nCRT, 2-6 weeks before surgery (tpost); nCRT delivered 41.4 Gy/23fr with concurrent carboplatin and paclitaxel. For patients that skipped surgery, complete clinical response (cCR) was assessed if patients showed no local relapse after 18 months; patients with pathological complete response (pCR) or with cCR were considered as complete responders (pCR + cCR). GTV volumes were delineated by two observers (Vpre, Vmid, Vpost) on T2w MRI: ERI and other volume regression parameters at tmid and tpost were tested as predictors of pCR + cCR. RESULTS Complete data of 25 patients were available at the time of the analysis: 3/25 with complete response at imaging refused surgery and 2/3 were cCR; in total, 10/25 patients showed pCR + cCR (pCR = 8/22). Both ERImid and ERIpost classified pCR + cCR patients, with ERImid showing better performance (AUC:0.78, p = 0.014): A two-variable logistic model combining ERImid and Vpre improved performances (AUC:0.93, p < 0.0001). Inter-observer variability in contouring GTV did not affect the results. CONCLUSIONS Despite the limited numbers, interim analysis of ESCAPE study suggests ERI as a potential predictor of complete response after nCRT for esophageal cancer. Further validation on larger populations is warranted.

Abstract
AIMS This study aims to describe our refined technique of submental intubation to avoid the recorded intraoperative complications related to tube passage and pilot balloon rupture. CASE SERIES This is a retrospective case series of 21 patients with complex maxillofacial trauma who underwent submental intubation from January 2019 to January 2023. All the patients underwent to the same procedure with a new technique of pilot balloon protection: the pilot balloon was not deflated because, once the connector was removed, only the tube was curved and passed through the incision extraorally while the cuff remained inflated. The wire of the pilot balloon was passed behind the last tooth so as not to interfere with the maxillary-mandibular fixation, remaining extraorally under the anesthetist's view. DISCUSSION Only 2 patients (9.5%) reported complications related to submental intubation: in particular a patient (4.8%) reported oral floor infection, and in another patient (4.8%) an unesthetic skin scar was observed. No patients reported intraoperative complications related to the procedure. CONCLUSION The technique of pilot balloon protection that we have proposed seems to be effective in reducing the intraoperative complications related to the passage of the pilot balloon, such as rupture, damage or early extubation.

Abstract
Introduction Cognitive deficits are considered a key feature of schizophrenia due to their substantial influence on the psychosocial outcome of subjects affected by this disorder. Several studies showed that moderate to severe cognitive impairments, including dysfunctions of social cognition, are already present during the early phases of the illness, in subjects with first-episode psychosis (FEPs). Psychosocial interventions, such as social skill training (SST), could therefore be implemented already upon occurrence of the first episode of psychosis to improve the overall functional outcome of schizophrenia, which represents to date an unmet need in the care of these patients. Objectives The study aims to evaluate the use of SST to enhance social skills and real-life functioning in FEPs. Methods The sample included 7 FEPs (age between 15 and 40). The SST intervention included 30 sessions lasting 2 hours and delivered twice a week. Psychopathology, neurocognition, real life functioning, functional capacity and social cognition were assessed at baseline ad after training. Paired samples t-tests were performed to evaluate the effects of the intervention. All subjects were treated with second generation antipsychotics. Results Significant improvements were observed in negative symptoms, social cognition, problem solving skills, as well as in global functioning (all p<0.05). Within real-life functioning, the improvement was greater for the domain of interpersonal relationships. Conclusions These preliminary findings suggest that SST might complement pharmacological treatment in FEPs to improve functional outcome in these subjects. Further studies with a higher sample size and a longer follow-up are required in order to confirm the present results.

Abstract
Introduction Social cognition and skill deficits have been largely documented in subjects with schizophrenia (SCZs), and have a strong influence on the functional outcome of these subjects. Different behavioural interventions have been developed to target and improve social skills in SCZs. For instance, the Social Skills Training (SST) focuses on improving communication skills and assertiveness to facilitate disease management, independent living and real-life functioning of SCZs. SST seems also to have an impact on negative symptoms and social cognition. Objectives The study aims to evaluate the effectiveness of SST in improving social cognition and negative symptoms in SCZs. Methods The sample included 8 chronic SCZs (age between 18 and 60), who completed 6 months of SST. The intervention consisted of two weekly group sessions of 2 hours each. We assessed psychopathology, neurocognition, real-life functioning, functional capacity and social cognition at baseline and after training. Paired samples t-tests were performed to evaluate the differences of the variables considered after completing the treatment. Results Significant improvements in negative symptoms (p<.05), social cognition (p<.05), functional capacity (p<.001), activities of daily living (p<.001) and interpersonal relationships (p<.011) were found. Conclusions The present findings suggest that SST might ameliorate social cognition and negative symptoms which are generally not influenced by antipsychotic treatment. The integration of pharmacological and SST interventions might have an impact on major determinants of poor real-life functioning in SCZs.

Abstract
BACKGROUND Preoperative evaluation of the number of lymph node metastasis (LNM) is the basis of individual treatment of locally advanced gastric cancer (LAGC). However, the routinely used preoperative determination method is not accurate enough. PATIENTS AND METHODS We enrolled 730 LAGC patients from five centers in China and one center in Italy, and divided them into one primary cohort, three external validation cohorts, and one international validation cohort. A deep learning radiomic nomogram (DLRN) was built based on the images from multiphase computed tomography (CT) for preoperatively determining the number of LNM in LAGC. We comprehensively tested the DLRN and compared it with three state-of-the-art methods. Moreover, we investigated the value of the DLRN in survival analysis. RESULTS The DLRN showed good discrimination of the number of LNM on all cohorts [overall C-indexes (95% confidence interval): 0.821 (0.785-0.858) in the primary cohort, 0.797 (0.771-0.823) in the external validation cohorts, and 0.822 (0.756-0.887) in the international validation cohort]. The nomogram performed significantly better than the routinely used clinical N stages, tumor size, and clinical model (P < 0.05). Besides, DLRN was significantly associated with the overall survival of LAGC patients (n = 271). CONCLUSION A deep learning-based radiomic nomogram had good predictive value for LNM in LAGC. In staging-oriented treatment of gastric cancer, this preoperative nomogram could provide baseline information for individual treatment of LAGC.

Abstract
BACKGROUND The increased use of the MATRICS Consensus Cognitive Battery (MCCB) to investigate cognitive dysfunctions in schizophrenia fostered interest in its sensitivity in the context of family studies. As various measures of the same cognitive domains may have different power to distinguish between unaffected relatives of patients and controls, the relative sensitivity of MCCB tests for relative-control differences has to be established. We compared MCCB scores of 852 outpatients with schizophrenia (SCZ) with those of 342 unaffected relatives (REL) and a normative Italian sample of 774 healthy subjects (HCS). We examined familial aggregation of cognitive impairment by investigating within-family prediction of MCCB scores based on probands' scores. METHODS Multivariate analysis of variance was used to analyze group differences in adjusted MCCB scores. Weighted least-squares analysis was used to investigate whether probands' MCCB scores predicted REL neurocognitive performance. RESULTS SCZ were significantly impaired on all MCCB domains. REL had intermediate scores between SCZ and HCS, showing a similar pattern of impairment, except for social cognition. Proband's scores significantly predicted REL MCCB scores on all domains except for visual learning. CONCLUSIONS In a large sample of stable patients with schizophrenia, living in the community, and in their unaffected relatives, MCCB demonstrated sensitivity to cognitive deficits in both groups. Our findings of significant within-family prediction of MCCB scores might reflect disease-related genetic or environmental factors.

Abstract
IntroductionCognitive deficits are considered central and persistent features of schizophrenia and have a significant impact on outcome and quality of life. The computerized interactive remediation of cognition (CIRCuiTS) is a new computerized cognitive remediation program aimed at improving different cognitive domains in patients with schizophrenia. In particular, the program was designed to mainly rehabilitate executive functions, attention and memory by training each cognitive function through several exercises and by improving metacognition.ObjectivesIn the present study, CIRCuiTS was translated and adapted into Italian. The applicability and feasibility of the Italian version was evaluated. Moreover, preliminary data on the effectiveness of the program were investigated.MethodsFour patients with a diagnosis of schizophrenia were recruited for the study. We investigated the changes in neurocognition, psychopathology, self-esteem and functional outcome at the end of the remediation program. The level of satisfaction of operators and participants was evaluated by means of the client satisfaction questionnaire (CSQ).For each patient, the entire program took place through 2 weekly sessions of 50 minutes for a total duration of 40 sessions.ResultsCIRCuiTS produced an improvement in all domains of neurocognition, disorganization, self-esteem and real-life functioning in the areas “self-care” and “interpersonal relationships”. Moreover, high levels of satisfaction were shown by CSQ for both, operators and participants.ConclusionThe Italian version of CIRCuiTS demonstrates high levels of acceptability and feasibility for both, patients and clinicians. Additionally, preliminary data suggest that the use of CIRCuiTS provides an improvement on several aspects of the disease.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionThe abnormal bodily phenomena questionnaire (ABPq) originates from the analysis of clinical files of more than 350 patients with schizophrenia. It consists in a semi-structured interview created to evaluate the subjective anomalies in feelings, sensations, perceptions and cognition in the domain of the lived body.ObjectivesThe present study is aimed at providing preliminary data for the validation of the Italian version of the ABPq.MethodsThe ABPq was translated and adapted into Italian. ABPq scores were correlated to those obtained by the schizophrenia proneness instrument, Adult version–body perception disturbances (SPI-A E, body) that evaluates the same kind of phenomena, in order to examine its convergent validity. Moreover, ABPq was correlated to psychopathological domains assessed by the Positive and Negative Syndrome Scale (PANSS) and by the Brief Negative Symptom Scale (BNSS).ResultsThe experimental sample included 40 clinically stable patients. Our findings showed a strong correlation between ABPq and SPI-A E, body. An association of ABPq total score with the positive and disorganized dimensions was also observed.ConclusionsOur preliminary data suggest that the Italian version of ABPq has a good convergent validity. The presence of abnormal bodily phenomena resulted to be associated to a greater severity of the disease and therefore it could be hypothesized that they represent an indicator of clinical severity.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionThe delay between psychosis onset and initiation of treatment (duration of untreated psychosis, DUP) is associated with a poorer treatment response and overall functional outcome. In Europe several early detection and intervention programs have been developed to reduce the DUP and promote Phase-specific Treatments (PsTs).AimsTo review the evidence of a) the effectiveness of European Early Interventions (EEIs) in reducing DUP; b) an impact of PsTs on clinical and social outcomes; and c) EEIs cost-effectiveness.MethodsA literature search in PubMed, PsychInfo, Cochrane and individual journals through cross-referencing was performed. All European Randomized Controlled Trials (RCTs) designed to reduce DUP and/or to implement PsTs for people with first-episode psychosis were included in the review.ResultsStudies examining early detection programs compared with Standard Care (SC) reported discrepant findings as to their impact on the DUP. PsTs generally reduce hospitalizations and improve service engagement when compared with SC; their impact on other clinical variables, e.g. symptomatology and social functioning, is unclear. Studies assessing EEIs cost-effectiveness in comparison with SC consistently report an advantage for EEIs in the long run.ConclusionsEEIs, as compared to SC, show several advantages that seem to result in an overall reduction in the cost of care. Therefore, the development of EEI is recommended.On the other hand, some inconsistencies in the reported results suggest that EEIs should include psychosocial interventions targeting unmet needs of schizophrenia patients, such as cognitive dysfunction and negative symptoms.Disclosure of interestSG received honoraria or Advisory board/consulting fees from the following companies: Lundbeck, Janssen Pharmaceuticals, Hoffman-La Roche, Angelini-Acraf, Otsuka, Pierre Fabre and Gedeon-Richter.

Abstract
IntroductionCurrent research suggested that avolition in patients with schizophrenia (SCZ) is not due to a deficit of hedonic experience, but to a poor ability to translate pleasurable experiences into motivational states. In line with this hypothesis, several evidences showed a preserved hedonic experience, even in the presence of severe trait anhedonia and avolition in SCZ.ObjectivesTo test the hypothesis that memory dysfunction, generally found in SCZ, could lead to inaccurate representations of emotional experiences and interfere with translation of pleasurable experience in motivation.AimsThe present study was aimed to investigate the relationships between state and trait anhedonia, avolition and cognitive functioning in 35 SCZ.MethodsIn SCZ and matched healthy controls (HC) the Temporal experience of Pleasure (TEPS) and Chapman's scales were used to assess trait anhedonia. The MID task was used to assess in-the-moment hedonic experience. Avolition was measured by the Schedule for the Deficit Syndrome. MATRICS Consensus Cognitive Battery was used to assess cognition.ResultsSCZ did not differ from HC on TEPS or on MID task performance but reported higher scores for trait social anhedonia. Trait social anhedonia was associated with memory dysfunction and showed a correlation with avolition.ConclusionsOur results confirm the disjunction between state and trait anhedonia and demonstrate a relationship of the latter with memory impairment and avolition, suggesting that inaccurate representations of emotional experiences might impede their translation in motivation to act.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionPeople with schizophrenia exhibit deficits in neurocognitive and social cognitive (SC) processes which limit their social reintegration. SC was found to mediate in part the impact of neurocognitive dysfunctions on real-life functioning.ObjectiveThe purpose of this study was to implement a new intervention for patients with schizophrenia, the Social Cognition Individualized Activities Lab (So.C.I.A.L.) which trains both social cognition and neurocognitive functions.AimsTo determine the efficacy of the So.C.I.A.L in improving SC by a comparison with a validated cognitive remediation (CR) intervention: the Social Skills And Neurocognitive Individualized Training (SSANIT).MethodsNine stabilized patients accepted to participate in this pilot study. Five were randomized to So.C.I.A.L. and 4 to SSANIT. The two programs were matched for the overall treatment duration (20 weeks), as well as frequency and duration of the sessions. Both interventions included individual sessions of neurocognitive individualized training; So.C.I.A.L included group sessions on Emotion Recognition and Theory of Mind, while SSANIT group sessions of Social Skills Individualized Training.ResultsNo group difference was found for changes in neurocognition, while a significant group effect was observed for changes in SC, due to improvement only in the So.C.I.A.L. group.ConclusionsThe study results showed a specific effect of the So.C.I.A.L. on SC, beyond the effect on neurocognition. Further studies are needed to assess the impact of So.C.I.A.L. on real-life functioning in a larger group of subjects.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Puroindoline A and puroindoline B from plant seeds, bovine lactoferrin and chicken eggs lysozyme are antimicrobial proteins of innate immune system that lyse invading organisms. We investigate their potential antibacterial activity against Listeria monocytogenes in a mouse model. Bacteria were isolated from various organs for 7 days after challenge. Livers displayed consistently higher bacterial count (up to 10(7)cfu/g) than spleens, kidneys and brains. The efficacy of the AMPs was therefore established by measuring the infection level (cfu number) of these organs. Puroindoline A and puroindoline B (5mg/mouse), lactoferrin and lysozyme (1.25mg/mouse), intravenously injected individually, inhibited bacterial growth completely. Puroindoline A, puroindoline B and lactoferrin were effective when administered 24h before infection; lysozyme was effective at the time of infection or 5 days after. Their combined use resulted in the enhancement of individual antibacterial activities. Complete inhibition of bacterial growth was observed using concurrently 0.059mg/mouse of puroindoline A and 0.019mg/mouse of puroindoline B, lactoferrin and lysozyme. Individual antimicrobial proteins reduced significantly the expression level of pro-inflammatory cytokines (IL-6, IL-8, INF-gamma and TNF-alpha), acute phase proteins (C-reactive protein and fibrinogen) and the T lymphocyte antigens CD4, CD8a, CD8b and CD25. These results suggest their potential use for the control of L. monocytogenes infections.

Abstract
Patients (305 patients with pulmonary tuberculosis) and controls (290 household genetically unrelated contacts) were tested by polymerase chain reaction (PCR) for polymorphisms in the intron 15 and the 5' untranslated region of the gene coding for the a3 isoform of the human ATPase gene. Diagnosis of pulmonary tuberculosis was based on chest radiography and sputum smear examination and confirmed by PCR and bacteriological tests. Alleles (two at each site) segregated in the form of four haplotype pairs: 13, 14 (very rare), 23, and 24. The 13/24 (double heterozygous) patients were protected against tuberculosis (OR: 0.15; P: 10(-8); CI: 0.08-0.3). The 13/13 vs 13/24 and 23/23 vs 23/24 (double homozygous) patients were susceptible to the disease (OR. 5.8; P: 6 x 10(-7); CI: 2.8-11.9; OR: 4.5; P: 5 x 10(-7); CI: 2.5-8.4, respectively).

Abstract
BACKGROUND Mannose-binding lectin (MBL) activates the complement system in an antibody-independent manner, enhances complement-mediated phagocytosis, and plays a major role in the regulation of inflammatory cytokine release by monocytes. METHODS Case patients (277 patients with pulmonary tuberculosis) and control subjects (288 household contacts) were tested by polymerase chain reaction (PCR) for polymorphisms at the promoter and the exon 1 regions of the MBL gene. Diagnosis of pulmonary tuberculosis, based on findings from chest radiography and sputum smear examination, was confirmed by PCR and bacteriological tests. RESULTS HYA/HYA subjects were protected against tuberculosis (odds ratio [OR], 0.09 [95% confidence interval {CI}], 0.023-0.408; P < 1 X 10 (-6)). LYB/LYD subjects were susceptible to disease (OR, 49 [95% CI, 2.9-812.5]; P < 1 X 10(-6)). CONCLUSIONS This study supports the conclusion that MBL can protect or predispose the host to tuberculosis, depending on the host's haplotype pair.

Abstract
Scientific evidences support the preventive role of physical activity in relation to different multifactorial pathologies. Health's promotion through the spreading of lifestyles that encourage movement, does not represent just an action in contrast with "sedentary life" risk-factor, but also a priority for "quality" of life, with relevant economical and social benefits. WHO indicates physical activity as one of the priorities for an effective prevention. Besides, the EU supports the realization and the diffusion of some prevention-programs. Main pilot experiences developed in Italy and other countries are summarized. Attention is focused on the role of the competences and structures involved in an integrated approach based on availability of medical support, social services and local structures, considering recent developments in health prevention and promotion. In Italy and Europe, new opportunities to implement health promotion through physical activity are offered by the development of higher education in movement and sport sciences.

Abstract
Several studies focused on the macroscopic architecture of increased cardiac wall induced by exercise training. Our goal was to evaluate myocardiocyte, interstitial and vascular component, and connexin-43 expression in endurance-trained mouse hearts. Sixty-three 10-week-old male Swiss mice were divided into four sedentary groups (C0, C15, C30 and C45) and three groups exercised respectively for 15 (T15-D; running intensity [RI]: 3.18 m/min; running duration [RD]: 75 min/first week and 150 min/second week), 30 (T30-D; RI: 3.96 m/min; RD: 150 min/third week and 225 min/fourth week) and 45 days (T45-D; RI: 3.96 m/min and 4.8 m/min, respectively for the fifth and sixth week; RD: 300 min) on a treadmill. Morphometric analyses were performed to quantify myocardiocyte size and number, and the capillary and interstitial connective tissue (ICT) area. We assessed the expression of ventricle myosin light chain-II, vimentin and connexin-43 by western blot analyses. Our results showed a hypertrophy of the interventricular septum and left ventricle in T30-D and T45-D mice that was not due to variations in myofibrillar content, myocardiocyte size and number, or ICT quantity but to a significant increase in the capillary area. The microvascular remodeling was associated with vimentin increased expression in ICT cells and connexin-43 upregulation. The first phenomenon might be related to an enhanced request of remodeling and growth factors; the second suggests a new role of connexin-43 in cardiac angiogenesis.

Abstract
Titin, a sarcomeric giant protein, plays crucial roles in muscle assembly, elasticity and stability. Little is known about titin adaptation to endurance exercise. We studied the effects of endurance training on titin expression in mouse gastrocnemius muscles (MGM). Sixty-three ten-week-old male Swiss mice were divided into seven groups. Four groups were composed of untrained control animals (C0, C15, C30, C45) instead the other three included mice trained for 15 (T15), 30 (T30) and 45 (T45) days by treadmill. The training protocol was mainly aerobic, characterized by moderate-intensity, rhythmic and continuous exercises. Titin expression was determined by immunohistochemistry on MGM sections. Results revealed a significant reduction in body weight of the T45 mice and a significant increase in titin expression (% titin immunoreactivity median [range] = 41.11 [20-60] vs. 30.00 [10-50]). It is postulated that the up-regulation of titin expression is an adaptative mechanism to increase muscle elasticity and stability in response to the high number of stretch-shorten cycles during endurance training. Such a mechanism may be important for minimizing muscle energy consumption and improving performance during running.

Abstract
Puroindolines are antimicrobial peptides that occur in wheat seed, and are characterized by broad antimicrobial activity. We describe the heterologous expression of puroindoline A and B in the Origami strain of Escherichia coli. The recombinant puroindolines showed the same antimicrobial activity on Staphylococcus epidermidis as compared to the native peptides (MIC(90)=30microgml(-1)). The bactericidal activity was 125microgml(-1) for recombinant puroindoline A and 42microgml(-1) for recombinant puroindoline B. Neither protein shows in vitro haemolytic activity or toxicity towards the murine macrophage cell line J774, but they are able to kill intracellular staphylococci. Our preliminary results suggest that recombinant puroindolines deserve further attention as alternatives to the conventional antibiotics in the control of S. epidermidis skin infections.

Abstract
The old Annurca apple cultivar (Malus domestica), particularly appreciated for its peculiar flavor and crispy flesh, was studied in order to preserve its ancient germplasm. Twelve clones of Annurca were analyzed using random amplified polymorphic DNA (RAPD) and simple-sequence repeat (SSR) markers. Two out of 30 RAPD primers and nine out of ten SSR primers were able to discriminate all the clones analyzed. Data were confirmed by measuring DNA content using flow cytometry. The results provide a good procedure to improve germplasm field management, in order to removing redundant material in the Annurca collection. This represents an efficient way to create a data bank in order to preserve the genetic variability of the Annurca cultivar.

Abstract
AIM In the treatment of the critically ill patients an adequate fluid therapy appears to be essential to optimize hemodynamics and to get a suitable tissue perfusion. In this study we have evaluated the effects of volume replacement, carried out with 2 different solutions: hydroxyethyl starch 6% (HAES) and albumin 20% (HA). METHODS Twenty patients suffering from sepsis were recruited and randomized into 2 groups. The first group was treated with hydroxyethyl starch 6% ( HAES treated group), and the second with albumin 20% (HA treated group). The volume of colloids was given to maintain pulmonary capillary wedge pressure (PCWP) between 15 and 18 mmHg. Daily, both hemodynamic parameters and blood gas analyses were monitored. RESULTS Groups were homogeneous for age, sex and pathology. During the treatment we observed that cardiac index (CI), right ventricular ejection fraction (RVEF), oxygen consumption index (VO(2)I), oxygen delivery index (DO(2)I), and rate between arterial oxygen pressure and fraction of inspired oxygen (PaO(2)/FiO(2)) were increased significantly only in HAES treated group (P<0.05). APACHE II score decreased significantly only in HAES treated group (P<0.05), contrarily to the HA treated group, in which we observed a non significant increase. CONCLUSIONS Since hydroxyethyl starch induced a hemodynamic and clinical improvement, these effects translated into an improvement of sensorium and a reduction of APACHE II score, without causing pulmonary edema, we can conclude that hydroxyethyl starch 6% ws 130,000 dalton ms 0.4 (Voluven) is an effective fluid for resuscitation of hypovolemic patients and represent an attractive alternative to albumin.

Abstract
Antimicrobial peptides and proteins are being studied with increasing interest because of their broad range antimicrobial activity. Among plant antimicrobial proteins, the wheat seed polypeptides, puroindoline a and puroindoline b, are particularly interesting because of their established antibacterial activity. In this paper we describe different strategies used to clone His tagged and GST tagged puroindolines obtaining 1.5 mg recombinant protein from 1 l culture. The antimicrobial activity of recombinant and native puroindolines was comparable.

Abstract
AIM Radiofrequency ablation (RFA) is a minimally invasive therapy for pulmonary malignant cancers in patients with medical co-morbidities or refusal of surgery. The aim of this study was to evaluate a conscious analgosedation protocol for RFA of lung neoplasm. METHODS Ten RFAs were performed. Following analgesic premedication patients underwent local anesthesia (lidocaine 2%) and propofol infusion. RESULTS The procedures were always uneventful. Postoperative severe pain was not reported; a deep sedation was required to allow the quick and safe management of RFA. CONCLUSIONS Spontaneous breathing sedation is safe in monitored and well-oxygenated patients and may limit the incidence of tension pneumothorax. Postoperative period needs a proper pain control for the first 24 h. Data on the long-term efficacy of lung tumor RFA are not yet available.

Abstract
BACKGROUND Posterior Reversible Encephalopathy (PRES) is characterized by acute-onset headache, altered mental status, cortical blindness and seizures, with parietal-occipital involvement. We report all cases of PRES diagnosed in our intensive care unit during the last 4 years, and evaluate their outcome in terms of the different medical treatments used. Even if usually reversible, PRES can sometimes result in death or irreversible neurological deficit, such as chronic epilepsy. MATERIAL/METHODS From January 2001 to January 2005, we identified 8 female patients with PRES. All patients underwent basal and follow-up brain MRI. Patients referred to Epilepsy Center (about 3000 patients) were reviewed in order to identify subjects with a clinical history of PRES. These latter were clinically re-evaluated and underwent video-EEG, MRI study and neuropsychological testing. RESULTS Of the 8 patients, 5 had hypertensive encephalopathy during pregnancy; 2 had eclampsia during the postpartum period; 1 patient with chronic renal failure developed symptoms after immunosuppressive treatment. In all patients but 1, neurological and radiological abnormalities resolved after appropriate treatment. In addition, we found 2 patients with temporal lobe epilepsy subsequent to a previous PRES. MRI revealed cortical-subcortical malacia in the parietal-occipital regions. CONCLUSIONS The widespread use of MRI technology has made PRES familiar to many clinicians. Although PRES is reversible when treatment is instituted, delayed diagnosis and therapy can result in chronic neurological sequelae. The relationship between hypertensive encephalopathy and chronic epilepsy needs to be confirmed by longitudinal studies. Normalization of blood pressure and treatment of seizures deserves particular attention.

Abstract
OBJECTIVE To evaluate whether baseline levels of plasma and CSF HIV RNA, tumor necrosis factor alpha (TNFalpha), monocyte chemoattractant protein-1 (MCP-1), matrix metalloproteinase-2 (MMP-2), or macrophage colony stimulating factor (M-CSF) are predictors of incident HIV-associated dementia (HIVD) in a cohort with advanced HIV infection. METHODS A total of 203 nondemented subjects with CD4 lymphocyte counts less than 200/muL, or <300/microL but with cognitive impairment, underwent semiannual neurologic, cognitive, functional, and laboratory assessments. HIVD and minor cognitive motor disorder (MCMD) were defined using American Academy of Neurology criteria. The cumulative incidence of HIVD was estimated using Kaplan-Meier curves. Cox proportional hazards regression models were used to examine the associations between biologic variables and time to HIVD, adjusting for age, sex, years of education, duration of HIV infection, type of antiretroviral use, premorbid IQ score, and presence of MCMD. RESULTS After a median follow-up time of 20.7 months, 74 (36%) subjects reached the HIVD endpoint. The dementia was mild in 70% of cases. The cumulative incidence of HIVD was 20% at 1 year and 33% at 2 years. Highly active antiretroviral therapy (HAART) was used by 73% of subjects at baseline. A plasma HIV RNA level was undetectable in 23% of subjects and a CSF HIV RNA level was undetectable in 48% of subjects. In adjusted analyses, neither plasma nor CSF HIV RNA levels (log10) were associated with time to HIVD; log10 levels of plasma TNFalpha (HR 3.07, p = 0.03) and CSF MCP-1 (HR = 3.36, p = 0.06) tended to be associated with time to HIVD. CONCLUSION The lack of association between baseline plasma and CSF HIV RNA levels and incident dementia suggests highly active antiretroviral therapy may be affecting CNS viral dynamics, leading to lower HIV RNA levels, and therefore weakening the utility of baseline HIV RNA levels as predictors of HIV-associated dementia.

Abstract
Puroindolines, for years largely investigated for their involvement in wheat kernel hardness, have recently attracted attention thanks to their possible role as antimicrobial proteins. With the aim to enhance our knowledge of these proteins we studied their localization in the kernel, and their antimicrobial activity in vitro against six different bacterial strains. Immunolocalization showed that both the PINs are strongly concentrated in the aleurone layer, but also highly present in the endosperm. Interestingly we observed that puroindolines not only have the same spatial distribution in the kernel, they are also always found co-localized. Their co-localization suggests that they could cooperate in defending the plant against pathogens. We therefore tested antimicrobial activity of PINA and PINB, and a putative synergism between these proteins. The results showed that the two polypeptides can in vitro inhibit growth of all the bacteria tested; furthermore when combined together they are able to enhance each other's toxicity. In view of their antimicrobial activity and of their natural presence in Triticum aestivum wheat flour, puroindolines look promising antibacterial agents and thus deserve further studies aimed at establishing their possible future applications in fields of food and health care. Since PINs were still detectable in bakery products, these proteins may be promising tools in investigating natural ways of food preservation.

Abstract
Extraterrestrial exploration has gone on for decades before reversible testicular failure was shown to be a consequence of space flight in humans and animals at the end of the XXth century. This phenomenon was initially thought to depend on the psycho-physical stress expected to derive from a decidedly unusual environment, but the lack of consistent data concerning cortisol increase and/or gonadotrophin suppression pointed to the possibility of a primary defect. This was indirectly confirmed by the observation that a continuum of testicular androgen secretion potential exists from microgravity to centrifuge-derived hypergravity. Further experiments using tissue slices and suspended cells confirmed a direct inhibitory effect of microgravity upon testicular androgen production. A parallel deterioration of major physiological parameters, such as bone density, muscle mass/force, red blood cell mass, hydration and cardiopulmonary performance, has been repeatedly described during space missions, which, luckily enough, fully recover within days to weeks after landing, the time lag depending on single organ/system adaptation rates. According to the Authors of the present review, when taking together all reported changes occurring in space, a picture emerges closely resembling the so-called aging male syndrome, which is currently the object of daily screening and clinical care in their endocrine unit, so that microgravity may become a tool for better understanding subtle mechanisms of testicular senescence.

Abstract
OBJECTIVE To determine the inter-rater reliability of a modification of the Memorial Sloan-Kettering (MSK) Staging for HIV-associated cognitive impairment. METHODS Data were abstracted on neurologic, neuropsychological, and functional status on 100 individuals participating at four sites in the Northeast AIDS Dementia (NEAD) Consortium cohort study, a longitudinal study of predictors of cognitive impairment in HIV-infected individuals. Neuropsychological performance was defined 1) based on the neuropsychologist's global impression and 2) solely based on neuropsychological test scores. Raters at each site used the abstracted data to assign an MSK stage to each subject blind to any identifying information. Inter-rater reliability was assessed using kappa statistics. Agreement between computer-generated ratings and site-generated ratings was also assessed. RESULTS Kappa statistics for pair-wise agreement among the sites regarding MSK stage ranged from 0.70-0.91, representing good to excellent agreement between sites. Agreement between computer-generated ratings and site-generated ratings was in the good to excellent range (0.62-0.79). CONCLUSIONS The authors have modified the MSK rating scale and developed a reliable instrument that can be used in multicenter studies. This instrument will be useful in staging HIV-dementia in future longitudinal studies and will be valuable in increasing accuracy of clinicopathologic studies.

Abstract
BACKGROUND Tourette syndrome (TS) and related tic disorders are commonly associated with obsessive-compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD). It has been argued, however, that any observed association between TS and these and other psychopathologies may be due to ascertainment bias in that individuals with multiple problems are more likely to be referred for medical evaluation. METHODS In order to overcome the potential confounding by ascertainment bias, the authors conducted a community-based study of school children using direct interviews to determine the prevalence of tic disorders and any comorbid psychopathology. A standard psychiatric interview and standardized rating scales were utilized to diagnose childhood behavioral disorders. RESULTS Of the 1,596 children interviewed, 339 were identified as having tics. The following psychopathologies were found more commonly (p < 0.05) in the children with tics: OCD, ADHD, separation anxiety, overanxious disorder, simple phobia, social phobia, agoraphobia, mania, major depression, and oppositional defiant behavior. CONCLUSION The behavioral spectrum of tic disorders includes OCD, other anxiety disorders, a mood disorder, and attention-deficit and disruptive behavior disorders.

Abstract
OBJECTIVE A new once-a-day methylphenidate (MPH) formulation, Concerta (methylphenidate HCl) extended-release tablets (OROS MPH), has been developed. This study was conducted to determine the safety and efficacy of OROS MPH in a multicenter, randomized, clinical trial. METHODS Children with attention-deficit/hyperactivity disorder (ADHD; n = 282), all subtypes, ages 6 to 12 years, were randomized to placebo (n = 90), immediate-release methylphenidate (IR MPH) 3 times a day (tid; dosed every 4 hours; n = 97), or OROS MPH once a day (qd; n = 95) in a double-blind, 28-day trial. Outcomes in multiple domains were assessed, and data were analyzed using analysis of variance and Kaplan Meier product limit estimates for time to study cessation. The primary time point for analysis was the last available patient visit using last observation carried forward. RESULTS Children in the OROS and IR MPH groups showed significantly greater reductions in core ADHD symptoms than did children on placebo. This was true both at the end of week 1 and at the end of treatment on the basis of mean teacher and parent IOWA Conners ratings. IR MPH tid and OROS MPH qd did not differ significantly on any direct comparisons. Forty-eight percent of the placebo group discontinued early compared with 14% and 16% in the IR MPH and OROS MPH groups, respectively. CONCLUSIONS For the treatment of core ADHD symptoms, OROS MPH dosed qd and IR MPH dosed tid were superior to placebo and were not significantly different from each other.attention-deficit/hyperactivity disorder, methylphenidate, OROS, Concerta.

Abstract
BACKGROUND Antecedents to human immunodeficiency virus-dementia (HIV-D) are poorly understood. OBJECTIVE To identify risk factors for HIV-D. METHODS Subjects who are positive for HIV who have CD4+ counts either below 200/microL or below 300/microL with evidence of cognitive impairment were enrolled in this study. Neurologic, cognitive, functional, and laboratory assessments were done semiannually for up to 30 months. Human immunodeficiency virus-dementia was diagnosed using American Academy of Neurology criteria for probable HIV-1-associated dementia complex. RESULTS One hundred forty-six nondemented patients were enrolled, 45 of whom subsequently met criteria for incident HIV-D. In univariate analyses using the Cox proportional hazards regression model, the following variables were significantly associated with time to develop dementia: cognitive: abnormal scores on Timed Gait, Verbal Fluency, Grooved Pegboard, and Digit Symbol tests; attention-memory, psychomotor, and executive function domain scores; and the diagnosis of minor cognitive/motor disorder; neurologic and medical: increased abnormalities on the neurologic examination, extrapyramidal signs, history of HIV-related medical symptoms; functional: higher reported role or physical function difficulties. Depression was also a strong risk factor, along with sex, hematocrit, hemoglobin, and beta2-microglobulin levels. In a multivariate model that used cognitive domain scores, covariates with significant hazard ratios included depression, executive dysfunction, and the presence of minor cognitive/motor disorder. CONCLUSION Cognitive deficits, minor cognitive/motor disorder, and depression may be early manifestations of HIV-D.

Abstract
Cognitive and functional outcomes are of primary interest in the design of efficacy trials in HIV-associated cognitive impairment. In a longitudinal cohort study, weak associations were found between measures of cognitive performance and commonly used measures of daily functioning (mostly self-report measures) in HIV-infected individuals. Modifications of current functional scales or new functional instruments are needed to assess the clinical relevance of cognitive changes in clinical trials of HIV-associated cognitive impairment.

Abstract
A battery of tests has been designed to explore functional disabilities in children 10-12 years of age arising from adverse conditions during early development. At these ages, it becomes possible to use more complex and challenging tests than those typically used at earlier ages. Although the battery was prompted originally by questions arising from methylmercury exposure, it was also designed for applicability to neurotoxicant exposures arising from pesticides, solvents, persistent organic pollutants such as PCBs and dioxins, other metals, and nutrient excesses and deficiencies as well. The test battery includes the following categories: (1) neuropsychological tests with established psychometric properties not widely exploited in studies of developmental neurotoxicity; (2) electrophysiological and behavioral tests of sensory functioning spanning a broader range of indices than those used generally in studies of neuropsychological development; and (3) adaptations of performance tasks used previously only in animals. The battery was developed in Rochester, New York, and then field-tested on a group of 61 children in the Republic of the Seychelles, where the Ministry of Health had established the Child Development Center. Our findings suggest a number of tests and procedures with the potential for inclusion in test batteries aimed at the exploration of adverse neurodevelopmental effects.

Abstract
Human exposure to methylmercury (MeHg), a known neurotoxin, is primarily from fish consumption. As part of a large study examining the association between MeHg exposure and child development in a population with high fish consumption we examined school-age behavior using the Achenbach Child Behavior Checklist (CBCL). The CBCL Total T score was a primary endpoint and was reported earlier to show no adverse association with prenatal or postnatal MeHg exposure. In this study we analyzed the T scores of the CBCL subscales to determine if more discrete aspects of measured behavior were associated with exposure. The Seychelles Child Development Study (SCDS) is a prospective, double blind, longitudinal evaluation of over 700 children. The index of prenatal exposure was maternal hair total mercury (T-Hg) in a segment growing during gestation. Postnatal exposure was T-Hg in the child's hair taken at 66 months of age. The child's primary caregiver completed the CBCL during the 66-month evaluation. No association between prenatal or postnatal MeHg exposure and the CBCL subscales was found. In Seychellois children exposed to MeHg from consumption of ocean fish we found no association between either prenatal or postnatal MeHg exposure and behavior as measured by the CBCL subscales.

Abstract
The Seychelles Child Development Study has been unable to confirm any relationship between maternal exposure to MeHg during pregnancy and adverse developmental outcomes. In this report, 87 children from a pilot cohort were evaluated at 9 years of age. Each child was given a battery testing specific cognitive, visual motor, and motor skills using standardized psychometric and neuro-psychological tests. The results indicated no adverse association between maternal MeHg exposure and any developmental outcome measure. For three endpoints (Boston Naming Test and two tests of visual motor coordination), enhanced performance in males was associated with increasing prenatal MeHg exposure. A secondary analysis including both prenatal MeHg and postnatal MeHg exposure was done even though we lacked postnatal hair for about 35% of the cohort. The results of the secondary analysis mirrored the outcomes of the primary analysis regarding prenatal exposure but were less robust. The results of this study are consistent with earlier findings from the 66-month evaluations of the SCDS Main cohort. Since MeHg is neurotoxic, this effect is likely due to other factors associated with consumption of fish.

Abstract
OBJECTIVE Analysis of health, neurodevelopmental, and school performance outcomes in a pilot study of term and near-term infants with respiratory failure due to pneumonia or meconium aspiration treated with surfactant. STUDY DESIGN Retrospective review of medical records, neurodevelopmental and psychosocial evaluations, and parent and teacher surveys. RESULTS Of the 14 patients enrolled, only one was rehospitalized, for pneumonia. Three were reported to have episodes of wheezing, two of whom required bronchodilators. One patient had unilateral hearing loss, one had a full-scale intelligence quotient that was below normal, and all but one patient for whom complete results were obtained were performing at or above grade level. CONCLUSION Term and near-term newborns with moderately severe respiratory failure treated with surfactant can, in general, be expected to recover completely and have normal general health, neurodevelopmental outcome, and school performance.

Abstract
UNLABELLED The Seychelles Child Development Study (SCDS) is testing the hypothesis that prenatal exposure to low doses of MeHg from maternal consumption of fish is associated with the child's developmental outcomes. No deleterious relationships between exposure to MeHg and cognitive functions have been identified in the primary analysis of the main cohort through 66 months of age. We performed secondary analyses to determine if effect modification (EM) from social and environmental factors was affecting associations between MeHg and outcomes. METHODS MeHg exposure was determined by analysis of maternal hair growing during pregnancy. Children in our Main Study cohort were evaluated at 6.5 months (N = 740) for visual recognition memory and visual attention using the Fagan Infantest, at 19 months (N = 738) and 29 months (N = 736) with the Bayley Scales of Infant Development (BSID). Interactions between MeHg and Caregiver Intelligence, Family Income and Home Environment were examined by multiple regression analysis. RESULTS The median prenatal MeHg exposure was 5.9 ppm (Range 0.5-26.7 ppm). No EM occurred for preferential looking or visual attention at 6.5 months, for the BSID Psychomotor Scale at either 19 or 29 months, or for activity level at 29 months as measured by the BSID Infant Behavior Record. Interactions between MeHg level and both caregiver intelligence and family income were statistically significant for the BSID Mental Scale at 19 months but not at 29 months. These showed enhancement of MDI scores with increasing maternal MeHg in higher caregiver IQ groups at several levels of family income. CONCLUSIONS In Seychellois children, consistent major EM by social or environmental factors were not identified. The small EM by caregiver intelligence and social factors at 19 months is consistent with the enhanced performance we reported when this cohort was examined at 66 months.
